Problems solved by technology

However, as the water flow in the water outlet channel increases, the pressure of the water flow on the switching element is also increasing, and the force required to keep the switching element at the second position is also increasing, which is very inconvenient for the user to operate.

Abstract

The invention provides an energy-saving spray gun which comprises a body, a starting piece and a switching piece. The starting piece is in linkage connection with the switching piece, and the starting piece is operated to control the switching piece to be switched between the first position and the second position; when the switching piece is located at the first position, a water outgoing channel and a water incoming channel in the body are separated; when the switching piece is located at the second position, the water outgoing channel and the water incoming channel in the body are communicated; a cavity communicated with the water outgoing channel and the water incoming channel respectively is arranged in the body, and the switching piece is mounted in the cavity; the cavity is provided with an avoiding space, so that the switching piece can be switched between the first position and the second position; the switching piece is provided with a through hole, and when the switching piece is located at the second position, the through hole partially leads water in the cavity to the avoiding space.

Description

technical field [0001] The invention relates to a labor-saving spray gun. Background technique [0002] Spray guns are widely used in many fields. There is a switch in the spray gun. When the switch is in the first position, the water outlet channel of the spray gun is blocked, and the spray gun cannot discharge water; when the switch is in the second position, the water outlet channel of the spray gun is opened. , the spray gun normally discharges water. When the water outlet channel is blocked, the water flow forms a pressure on the switching member, and the pressure increases continuously with the increase of the water flow velocity. Therefore, the user needs to overcome this pressure to switch the position of the switching member from the first position to the second position, which is very laborious. In extreme cases, excessive water pressure can even rupture the switch. Moreover, when the switching member is switched to the second position, in order to maintain the ...
