What is the correct way to inhale and exhale an e-cigarette?

After the smoke is inhaled into the mouth, it pauses briefly in the mouth for 2 to 4 seconds, then slowly exhales through the nasal cavity without swallowing through the throat.

The first correct way to smoke is to replenish sufficient water before smoking. Water is tar's natural enemy. Water can excrete most of the harmful substances produced by smoking from the body through the urethra. Therefore, healthy smoking requires smokers to smoke while maintaining the body's water balance and form the habit of drinking water first and then smoking.

When you start smoking, it is recommended to inhale through your nose. You are less likely to choke. Just use a little more force than pretending to smoke. Take a drag of a cigarette, open your mouth. and let the smoke waft up to your nose. After inhaling, use your throat to breathe in a little, first through your nose then through your mouth. AprAfter taking a drag of a cigarette, inhale first through your nose, then through your mouth. inhale lightly through your mouth for the remaining cigarette.

Detailed information

When using electronic cigarettes, you will continue to smoke until the cartridge runs out or the battery is recharged. In fact, it is not good to smoke like this for a long time. This not only affects the lifespan of the e-cigarette, but also the liquid contained in the cartridge cannot evaporate optimally. The correct way to use electronic cigarettes is to take a slight break from smoking for a while. This will not only protect the electronic cigarette well, but also relieve the feeling of smoking. After all, most consumers buy e-cigarettes to quit smoking.

The atomizer of electronic cigarettes must be cleaned frequently, because after a long time itperiod of use, the non-volatile liquid will condense and adhere to it. If excessive buildup occurs, it will affect the heating of the atomizer and. render the cartridge unusable. We can use a damp cloth dipped in a little alcohol or water to slowly wipe it. It is generally recommended to clean it once a week.

Comment IT168 Last week, Lenovo Group spent $2.91 billion to officially complete the acquisition of former industry giant Motorola Mobility. At this point, Motorola Mobility is officially part of Lenovo and Lenovo has become the third largest smartphone manufacturer in the world. Lenovo's S90 is the first machine after the merger. The appearance of this machine is somewhat similar to Apple's iPhone 6, which has also attracted the attention of many users. Lenovo's S90 is priced at 1,999 yuan and comes in Gemstone Silver, Pinkdiamond, platinum gold and titanium gray. "Click to see details

We know that it takes at least 12 months from design, development and production of a product. In the past, Lenovo was more about carrier products, with more low-end products, but this time it is when designing and developing mid-to-high-end products that the needs of Internet users are more considered. Everyone can choose the same. technical treatment for the "Bamboo Shooting Tip", but Lenovo offers different design points, including how the antenna is handled, and the camera does not have a protrusion, front fill light Even in terms of price. , Lenovo only costs less than 2,000 yuan, while Apple costs 6,000 yuan Lenovo S90 main parameters >

As usual We also want to briefly review the main hardware configuration of Lenovo S90 Lenovo S90 is a mid-to-high-end smartphone priced at 2000 yuan. It combines 5 inches 1280 x 720 pixels and 13 million. of pixels + 8 million pixels Of course, this is not its strong point. The most remarkable thing is.that the Lenovo S90 has a 1.2 GHz Qualcomm Snapdragon 410 (MSM8916) quad-core processor and a front flash. yuan. For mobile phones, this is still relatively rare.

To be honest, when I first saw the Lenovo S90 on the Internet, I really had the impression that it was the same as the Apple iPhone 6. I bought the Lenovo Bamboo S90, I didn't have such a strong feeling. Maybe the comparison of details was too serious. If we look closely, we can still see many differences, such as the four-leaf clover petal on the front, the. volume button on the right, etc. It was conceived. It even surpasses the Apple iPhone 6 in some aspects, such as antenna processing, camera protrusion and more reasonable body size.

The Lenovo S90 has one. 5-inch screen with 1280 x 720 pixels. The pixel density of the screen reaches 294 ppi. Since the Super AMLED screen adopts the layoutPentile ition, the color performance is very good. Additionally, the overall feel of the Lenovo S90's 5-inch screen is slightly better than that. of Apple iPhone 6, because for Android users, I have become accustomed to large screen mobile phones, so 5 inches can be considered a better size at the moment. Of course, for Apple fans, the 4.7-inch iPhone 6. has the essence of Apple.

The top of the Lenovo S90 The S90 is also very interesting. In addition to the conventional earpiece, camera and light/distance sensor, it also adds a flash as a veteran mobile. phone manufacturer, Lenovo also knows how to do this. User needs. Nowadays, men and women, young and old, like to take photos with their mobile phones and upload them to social media, and most female users need a powerful camera to satisfy their love ofthe beauty. Therefore, the 8 megapixel front camera + front flash of Lenovo Sunjian S90, which focuses on taking photos, will definitely meet the needs of all beauties.

If you say it looks like an apple, you must not have looked closely. The Lenovo Bamboo S90 also has a strong Lenovo style. The four-leaf clover-shaped home button has been used since the telephone era, but the paint on the button now looks more premium. However, what I also have to complain about here is that the Home button does not support the return to home page function. We always have to go back step by step before we can access the main interface. I don't know if it's because of the engineering machines we have. I hope the official foreign version can be improved.

Of course, we can't say that Lenovo's S90 is not similar to the iPhone6 from Apple. The body of the two is still somewhat similar. For example, the wire processing just mentioned, the absence of camera protrusions and other designs are all more user-friendly than the design of the Apple iPhone 6.

First of all , the back of the Lenovo S90 is very neat, elevating Lenovo's design concept to a higher level, which is Lenovo's trump card this time. Lenovo S90 S90 uses aluminum alloy as the whole machine material, and the zoom is smooth. First of all, this kind of metal material will give us a good feeling, and secondly, the body weight of 129g is also relatively moderate. Looking at the whole body, we can find that the antenna processing of Lenovo S90 is also very good, and there is no antenna line phenomenon that the public complains about.

The antenna on top looks more like the 4G version of Apple's iPad antenna, but Lenovo icleverly designed on top of the fuselage, so it doesn't seem obtrusive. Here we also discovered an unavoidable reason, namely the dyeing of jeans. After a few days of use, I noticed some stains on the top of my jeans, but I could just wipe it off with a damp cloth.

The Lenovo S90 uses an injection-molded antenna design at the bottom of the fuselage. We can see that Lenovo uses injection molding to open the integrated metal fuselage to ensure the reception and overflow of antenna signals. We can carefully see that in terms of antenna injection molding process, the workmanship of Lenovo S90 is still good. The overall surface and metal body maintain a good level and are smooth.

Of course, online complaints don't come out of nowhere. If we simply look at the bottom of the fuselage, we can see the silhouette of the Apple iPhone. But the high-Symmetrically designed speakers and microphone amplifier look more high-end and sleeker. What should be noted here is that the speaker is on the left and the microphone is on the right. In addition, it is a pity that the inferior interface of Lenovo S90 is not worth the built-in OTG data transmission function.

The Lenovo S90 also has a non-removable battery, and the two Micro SIM card slots can be removed via the card pin on the right side of the fuselage. It also supports China Mobile 4G LTE, but Micro SIM2 only supports GSM network. If you own a 4G mobile phone, you need to put it in the wrong card slot, otherwise you will not be able to use the 4G network.

Lenovo S90 adopts the latest VIBE 2.0 UI, which is an optimized custom operating system based on Android OS 4.4. This time, VIBE UI has changed the silly and brutal feel ofe interface and added many new features. Let's take a look below.

The unlock interface of VIBE UI2.0 of Lenovo S90 is quite beautiful. At present, VIBE UI2.0 also provides three hotkeys, namely call, information and photos. We have more different icons in which you can quickly access the corresponding interface by swiping up from the bottom. Unfortunately, these three shortcut icons cannot be customized and changed. It would be great if they could be modified to call, WeChat and take photos.

The main interface of VIBE UI2.0 still has a strong Lenovo style, but the system icons have been carefully optimized. The new design uses flat icons to keep VIBE UI2.0 up to date, but its flatness is slightly different from Apple iOS8. Take a closer look at the game center, the camra, system settings and other icons. There are shadows in the graphic structure. This can make flat icons less rigid and more acceptable to most users.

Many friends know this function of Eggplant Express. Simply click on “I want to send” or “I want to receive” to carry out different operations. Eggplant Express can not only transfer photos, music and videos, but also apps and contacts. This feature does not require an external network and is much faster than Bluetooth. It can be said to be an essential software for data transfer when changing devices.

Lenovo VIBE UI2.0 also adds side buttons to illuminate the screen and an ethereal touch. As the name suggests, the side button to turn on the screen can wake up the screen using the power button, increase or decrease the volumeme. Of course, double-clicking the screen can also light up the screen in a black screen state, so that. the screen can be charged quickly at night or when it is inconvenient to touch the power button.

Lingkong Touch is actually a shortcut button. Friends who have used iPhone must know that there is a virtual button in the phone settings. We can use this virtual button to implement some on a daily basis. operations. VIBE ROM also has virtual buttons, but they are not designed for disabled people, but to give large screen mobile phones a better operating experience. We can use virtual keys to quickly call up shortcut apps, frequently used switches, return, etc.

The Lenovo S90 is equipped with a 13-megapixel main camera. The most important thing is that it solves the problem of protrusion de the camera. This way we can avoid wear and tear on the camera during daily practical use. Additionally, the front flash can also be greatly improved in low light.

In the photo interface we can choose normal, panoramic, scanned photos and various special effects. This time we also found composition auxiliary lines on Lenovo S90

Here we can choose four-frame, nine-frame and equiangular spiral auxiliary lines. Thanks to these auxiliary lines, we can correct the angle of the photo and take more interesting photos. Okay, without further ado, let me look at the evidence.

Through testing, we can see that Lenovo S90 can basically meet most environments. needs, but in outdoor night scenes there will be a distinct lack of detail, which is also considered terrible. After a few days of experience, we also said that it is recommended to take photos with sufficient light. In addition, although the front flash can compensate for the shortcomings of insufficient light in low light conditions, we almost never take selfies in low light conditions, and there are not many users of all front flashes. Furthermore, I personally find this age test to be very flattering, but can we optimize the age first? Brother is obviously only in his twenties.

This year can be considered a year for 64-bit processors. Qualcomm also launched the 64-bit Qualcomm Snapdra processorsgon 410 and 610. This time, the Lenovo S90 is also the first to be equipped with a 64-bit 1.2GHz Qualcomm Snapdragon 410 (MSM8916) quad-core processor. The main feature is that it supports 64-bit and is equipped with Adreno 306 graphics chip, can support 1080P Full HD video playback and 13 megapixel camera, and fully supports various network standards LTE 4G and 3G, and has dual SIM and triple SIM card functions.

Since this 64-bit processor also integrates the Qualcomm Qualcomm RF360 front-end solution, in addition to powerful comprehensive network compatibility performance, it also supports NFC near-field communication, Wi-Fi connection , FM and Bluetooth technology, and fully supports current major navigation systems, including GPS, GLONASS, Chinese Beidou Star, etc.

We can see in the AnTuT test softwareu 5.0 that the 1.2GHz quad-core processor of the Qualcomm Snapdragon 410 (MSM8916) is a mid-level processor, and the Lenovo Sunjian S90 The current score is 19,187 points. Generally speaking, this remains within the normal range. For large-scale game users, it is recommended to use an iPad with a larger screen to play.

Lenovo S90

It adopts a removable battery design and is equipped with a 2300 mAh lithium battery. Although it is not removable, it can still meet the daily needs of users. In order to better simulate actual usage, the author tracked and recorded the battery usage of Lenovo X2 mobile phone during moderate usage. inIncluding calls, WIFI video viewing, local video playback, local MP3 audio playback, games and photography and charging effects testing. PS: this battery life test is also the standard testd battery life of the IT168 mobile channel. You can refer to other models for comparison.

After passing the author's real simulation test, the remaining battery charge is 11%. This test session does not include the 8-hour standby battery life test. Lenovo S90

There are almost no problems in a normal day. If, like me, you are an obsessive-compulsive person when it comes to cell phone power, it is also recommended to carry a mobile power supply with you for charging.

After a few days of simple and practical use, the performance of the Lenovo S90 is quite good, since I do not use it as my main machine, and I am quite satisfied with it in terms of taking photos , battery life, etc. In fact, what I'm most happy with is its one-piece metal body. Rounded corner design makes it niceand in hand! But the downside is also the appearance, which is too similar to Apple's. I hope Lenovo will design more excellent products on the S series in the future. The Lenovo S90 is currently on sale on JD.com, priced at 1,999 yuan.

It is available in Gem Silver, Diamond Rose, Platinum Gold, and Titanium Gray. "Click to see details
