V. Description of the invention (i) The present invention is a push-button spray gun, which is provided with a button on one side of the spray gun body, and the user can press the button to control the spraying of water or not, to achieve the effect of convenient manipulation. The application range of water spray private is quite wide. The most common is in gardening or car washing. It can provide water supply and water stop control functions. At the same time, various water supply can be changed by adjusting the spray head. Type, it is indeed convenient to use. · In the existing water spray design, most of the body is designed as a grip type, and the end of the grip is connected to a water pipe, and the other end of the grip is equipped with a water spray. The water head is also provided with a pressing handle on one side of the handle. When the user uses the holding handle, the pressing handle is controlled by four fingers. When the pressing handle is pressed against the handle, it is set in the body. The valve is opened, and the water flow in the water inlet is sprayed from the nozzle of the sprinkler head. When the pressure handle is released, the valve in the body is closed and the water flow is stopped. The design of some water spray grabs did not take into account the long-term use of the user. When the user needs long-term use, four fingers must be continuously applied to the pressure handle, which is not only easy for the fingers to feel. Fatigue, or even discomfort such as cramps or pain, in order to solve this problem, in some water jet design, a buckle or similar clamping structure is added on the side of the pressure handle, and it can be When pressing the handle to supply water, the pressure handle is locked to maintain a constant supply of water, so that the user does not have to apply force to the pressure handle all the time, so that the user will not feel tired during a long period of water supply. In the current design of the water spray structure of Keshu, it has already met the basic functional requirements of users, but in terms of the operating habits of ordinary users, it still cannot meet the operation requirements of ergonomics because the water spray is in the design Time 3 ^ The paper size applies the Chinese National Standard (CNS) A4 specification (21〇χ 297 mm) -------- A7 B7 V. Description of the invention (of) Two knowledge is used as the basis, which is the The design of the grip and the opening angle and radian of the pressure handle, etc., are based on the average size of the palm of the average person. It is matched, but in general use, it is found that the general water jet grab cannot be applied to the mother's personal patriarch | If the distance is too large or too small, the total distance between the main body and the pressure handle is too large. When the distance is equal to the day, the method is appropriate to apply force to the handle. This kind of situation is helping children: grip ^ is Common 'At this time, most children must use a hand to hold a water jet to grab the book: two t: use another hand to press the handle' It is not only difficult to operate, at the same time to the finger 'and when the distance is too small, the finger is not easy to exert force, In view of the distribution of joints and muscles, it is easiest to apply force Position that Tiger / second - between the finger sections, specification grab if water is small and pressure plate so that only the body: the web space between the user's palm and fall on the third knuckles, respectively, certainly not easy to force the user operation. … 'In the notion of generality, most Europeans and Americans have larger palms, while Dong Er: the palms are smaller, which has caused a considerable brother to the design of the water jet grab,' Life-producing manufacturers can rely on Locks are sold to different regions to adjust the specifications of the water spray rush products. But in fact, the palm size of each person is quite different. The difference between adults and children is greater. However, the design benefit of the water spray rush body is just like clothes or shoes. Produced various models for users to choose. 'Users ca n’t buy and use ^ different sizes of water spray guns to replace them according to the different palm size of each member of the family. Therefore, the existing water spray gun design is mysterious. ㈣ 水 ㈣ 结构,.
