Embodiment 1

[0011] A water-saving and flow-limiting spray gun described in Embodiment 1, such as figure 1 As shown, the gun body 3 and the gun head 10 are included, the gun head is provided with a nozzle 14, the gun body is provided with a spray gun switch 13 for controlling the water discharge, and the nozzle is provided with a flow-limiting water-saving device. Such as figure 2 Said, the flow-limiting water-saving device includes a water-saving seat 1, the water-saving seat is provided with a water-saving piston 2, the water-saving piston is provided with a water inlet 11 and a water outlet 12, and the water-saving piston is covered with a spring 4; A spiral baffle 8 is provided in the water inlet. Further, the width of the baffle is one-third of the diameter of the water inlet. The design of the baffle reduces the caliber of the water inlet by two-thirds. When the caliber is reduced, the water pressure and flow rate increase naturally, and the special spiral structure is adopted to ...

Abstract

The invention discloses a water-saving and flow-limiting spray gun. The water-saving and flow-limiting spray gun comprises a gun body and a gun head. The inside of the gun head is provided with a spray nozzle, and the gun body is provided with a spray gun switch for controlling water output; the spray nozzle is provided with a flow-limiting water economizer which comprises an economizing seat, the inside of the economizing seat is provided with an economizing piston, a water inlet channel and a water outlet channel are formed inside the economizing piston, and a spring sleeves the economizing piston; the inside of the water inlet channel is provided with spiral retaining pieces. Further, the width of the retaining pieces is one third as much as the diameter of the water inlet channel. By means of the retaining pieces, the diameter of the water inlet channel can be reduced by two thirds, accordingly, the water pressure and the velocity can be increased; through the special spiral structure, the direction of the water can be divided continually and the flow velocity of the water can be increased.

Description

technical field [0001] The invention relates to the field of sanitary equipment, in particular to a spray gun with the function of saving water and limiting flow. Background technique [0002] Under normal water pressure, the large spray guns in the prior art are generally equipped with a pressurized structure to increase the strength and flow rate of the spray gun water, and all adopt the method of reducing the water outlet diameter. However, due to the structural limitations of the prior art spray guns, the spray gun A lot of water ejected during water spraying is wasted, and when the water pressure is low, the spray gun just fails to achieve the effect of the original high-speed jet flow, and its water pressure is often not high and the flow rate is low, which causes a lot of Moreover, no matter when the water pressure is normal or low, the spray gun of the prior art is due to structural limitations, and its ineffective water use and water waste are very serious, resultin...
