First, the non-pressure type, which is the type installed on the roof. This water heater is inexpensive.

How to use the fan hat.
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 qWhat we saw when I was a child used a combined innovation method to combine the principles of solar power generation, fans and hats, allowing me to enjoy the breeze brought by the mini fan while protecting myself of 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 uss keep warm.
Nowadays, people not only look for high-end, but also convenience and comfort. the problem of winter and summer. Question, why not?
It runs on solar energy and the small fan will turn 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, makingt operate the fan and achieves a cooling effect.
However, the hat fan with fan in the above-mentioned prior art can only be attached to a certain hat, so the same hat can only be worn every day, it therefore needs to be improved. .
