Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of bathroom products, and particularly relates to a push button type spray gun. BACKGROUND

[0002] Spray guns have a very wide range of uses in life and can be used in kitchens, bathrooms, gardens, balconies, car wash lines and other places. The water outlet control of traditional spray guns is controlled by an angle valve or a faucet connected thereto to turn on and off, and in this mode, the user cannot control the water outlet of the spray gun in time. Therefore, most existing spray guns have a water outlet switch arranged on the spray gun body, specifically by arranging a switch valve on the spray gun body, pressing a switch handle configured in linkage with the switch valve to open and close the switch valve, so as to correspondingly control the on-off of the water outlet of the spray gun. For example, a spray gun disclosed in Chinese patent CN215235096U realizes the on-off control of water flow by pressing or releasing the switch handle to move the valve body. In this case, since the movement of the valve body needs to rely on the lever force formed by the switch handle, the size of the switch handle extending outward needs to be large enough to drive the valve body to move, which also affects the appearance of the spray gun and makes the overall appearance less attractive. At the same time, when the hand releases the switch handle, the valve body will automatically reset under the action of the elastic member, so that the user needs to continuously press the switch handle during use to maintain the required water outlet state, which is not convenient for the user to use. SUMMARY
