It runs on solar energy and the small fan starts to spin in the sun.
The hat is an item often worn in daily life. It can provide sun protection and a beautiful appearance. However, because summer is too hot, even though ordinary hats can provide sun protection, they are still uncomfortable. very hot. The Chinese patent (200720028463.4) describes a hat with a fan. There is a solar panel on the top of the hat, a fan on the bottom of the tongue, a switch on the fan, and the solar panel and the fan. are electrically connected. When it's hot, turn on the switch to allow the solar panel to power the fan, which makes the fan work and achieves a cooling effect.
However, the fan of the hat with fan in the prior art mentioned above can only be fixed on a certain hat, ofso the same hat can only be worn every day, so it needs to be improved. .
Is the solar fan cap easy to use? I heard that if you blow it for a long time, you will get a headache? Can elderly people use it?
On hat innovation
? As we all know, hats can make us look more beautiful and have a different sense of personality. Many people like to wear hats to show their charm. . , peaked caps, baseball caps, wool hats, cowboy hats, etc., the flow is endless. Nowadays, with the development of science and technology, people use their innovative thinking to create new products. For example, the small solar fan hat we saw when I was a child used a combined innovation method to combine the principles of power generationsolar, fans and hats, allowing me to enjoy the breeze brought by the mini fan while protecting me from the sun. In summer, the brighter the sun, the more refreshing the wind is for us.
? This also reminds me of another innovative way since hats can be designed to keep us cool in the summer, they can also be transformed to keep us warm in the winter. I think we should use the combined method of innovation and systems thinking. The solar device remains unchanged and can be used to store energy. Adding a device capable of installing batteries (in case of no sun) can release stored energy at any time. and converts it into energy in the form of thermal energy, it releases “hot air” to keep us warm.
Nowadays, people not only look for high-end, but also comodity and comfort. the problem of winter and summer. Question, why not?
Hello, the fan cannot blow directly on the head. Here are the specific points: Misunderstanding 1: Take a long breath. Many people like to blow on the electric fan for a long time. However, if they blow against the electric fan for a long time, the body temperature will drop due to sweat evaporation, which can easily cause colds, colds, abdominal pain. diarrhea and other illnesses. Use an electric fan, usually blowing for 0.5 to 1 hour at a time. Misunderstanding 2: Blowing at high speed. In order to cool down as quickly as possible, some people turn on the electric fan at the highest speed, thinking that the wind is strong and pleasant. This is an inappropriate practice. When the temperature exceeds 30°C, the air temperature is close to thatof human.At normal body temperature, the wind blown by the electric fan is actually high temperature wind. At this time, the heat of the human body should be mainly dissipated by the evaporation of sweat. If the fan blows too hard, the skin surface temperature. will fall, the pores will be blocked, and the sweat inside the body will not be emitted, and the body will not be able to evaporate. You will feel hot and you will also experience symptoms such as fatigue, back pain, etc. is called “holding in sweat”. When using an electric fan, it is not advisable to blow air at high speed. The correct way is to adjust it to medium to low speed to blow a gentle breeze. Misunderstanding 3: The wind is blowing near you. The electric fan should not be used very close to the body. If a strong wind blows nearby and blows only on one side of the body, sweat from the side of the skin thatreceives the wind will evaporate quickly and the temperature will drop considerably, while the sweat on the side not exposed to the wind will evaporate slowly. As a result, the gap between blood circulation and sweat excretion on both sides of the body is too large, and the nerve center will lose balance. Once time has passed, various organs. will be exhausted, leading to general discomfort. Use an electric fan, preferably 2 meters away, so that the wind blows evenly and gently. Misunderstanding 4: Directional wind blows. Today's electric fans are mostly oscillating fans. When blowing, the fans constantly change direction, forming a large and small wind, which will not make people feel too cold and the temperature will be uniform. Therefore, it is better to use an oscillating fan rather than blowing directional wind. Misunderstanding 5: Blowing while sleeping. Whenhen a person sleeps, the functions of various organs of the body will be reduced to the lowest level, reflexes will disappear, immunity will decrease, and diseases will easily occur. Therefore, you should not blow the fan for a long time while you sleep. Usage: Try using a medium or slow speed. Normally, turn on the fast speed first, then use the slow speed after cooling to reduce the power consumption of the electric fan. When using the electric fan, it is best to place it next to the door or window to facilitate air circulation, improve the cooling effect and reduce energy consumption. Make sure things go well. Pay attention to the daily maintenance of the fan. Maintain its good performance and avoid blade deformation, vibration, etc., which promotes to a certain extentenergy savings.
