[0002] Spray guns are widely used in all walks of life, especially in home life for cleaning kitchen utensils, washing cars at home, watering flowers, etc. However, many spray guns on the market cannot control the flow pressure, and there is no adjustable device for product functions, so there is only a fixed output mode, which cannot meet different requirements. If the operation is not appropriate, it is easy to damage the flowers.

[0030] The handheld handle module 200 includes a (hollow) connecting tube 210, a handle 220 and a handle fixing screw 230, wherein the connecting tube 210 is plugged into the connecting fixing end 1131 and the handle 220 is sleeved on the connecting tube 210, and the handle 220 is fixedly mounted on the base 113 by the handle fixing screw 230;

[0031] The push switch module 300 includes an integrally formed pressing end 310 , a driving protrusion 320 and a shell connecting end 330 , wherein the driving protrusion 320 contacts an end of the valve stem sliding block 1121 away from the switch reset spring 123 and the shell connecting end 330 is connected to the switch mounting end 1122 via a switch fixing bolt 340 .

[0032] Specifically, the housing unit 110 further includes a switch protection frame 115 , one end of the switch protection frame 115 is mounted on the first pipe section 111 and the other end of the switch protection frame 115 is mounted on the handle 220 .

[0033] More specifically, one end of the connecting pipe 210 away from the base is connected to a water supply device, and an internal pipeline is provided in the base 113 , and the connecting pipe 210 is in communication with the internal pipeline.

[0034] Furthermore, the cleaning nozzle 114 is provided with a cleaning outlet 1141 .

[0035] Furthermore, an adjustment return spring 126 is provided between the adjustment fixing seat 122 and the adjustment rotary cover 125 .

[0036] For this utility model:

[0037] A valve stem fixing nut is installed on the left side of the middle opening on the shell unit of the spray gun module (i.e., the side of the first pipe section close to the second pipe section), and a valve stem sliding block is installed on the right side of the middle opening (i.e., the side of the second pipe section close to the first pipe section). The valve stem is inserted from the left side of the shell, passes through the valve stem fixing nut and the valve stem sliding block respectively, and is connected to the valve stem sliding block with an elastic pipe pin. An EPDM sealing column is installed at the front end of the valve stem and connected with a pin. A cleaning nozzle is installed on the left side of the shell unit as a cleaning outlet during operation.

[0038] Install the tail adjustment fixing seat on the right side of the housing unit. Before installing the adjustment fixing seat, install the switch reset spring, then screw in the adjustment screw, install the adjustment reset spring, cover the adjustment screw cap, and screw in the screw cap fixing nut;

[0039] For the handheld handle module, the connecting (copper) tube is screwed into the bottom of the housing unit, and the plastic handle is put on and fixed with the handle fixing screw.

[0040] Insert the opening of the push switch module from bottom to top into the middle opening of the housing unit, pass through the valve stem and the valve stem sliding block, align with the hole on the switch mounting end and drive the convex end to be tangent to the end face of the valve stem sliding block at the same time, install the switch fixing bolts and adjust the screw cap fixing nuts, and finally install the switch protection frame.

[0041] During normal use, according to the use requirements of different scenarios, the flow pressure is adjusted first. When the adjustment cover is rotated, the flow rate can be increased or decreased. When the adjustment cover is rotated, the adjustment screw drives the adjustment fixing seat to rotate, thereby adjusting the depth of the part of the adjustment fixing seat built into the second pipe section, thereby changing the distance between the adjustment fixing seat and the valve stem sliding block. Finally, when the driving convex end drives the valve stem sliding block through the pressing end, the distance the valve stem moves is changed, thereby changing the size of the gap opened by the sealing column, thereby changing the amount of liquid flowing out of the cleaning outlet;

[0042] When the screw cap is adjusted clockwise, the flow rate and pressure will decrease. Conversely, when the screw cap is adjusted counterclockwise, the flow rate and pressure will increase. The flow rate can be adjusted from 0 to the maximum range.

[0043] After the flow rate is adjusted, it is only necessary to adjust the push switch module to the set position, that is, to press it until it cannot be pressed anymore. The working medium (water, gas) enters from the inlet, passes through the gap opened by the EPDM sealing column (5), and is discharged from the cleaning port to realize the operation of the spray gun.

[0044] The beneficial effects of the utility model are:

[0045] The improved adjustable cleaning spray gun can adjust the pressure and flow rate at any time and anywhere;

[0046] This product can be used in various pressure situations (including high, medium and low pressure situations), and all accessories are made of aluminum alloy and copper alloy, ensuring that the spray gun has sufficient strength and durability.

[0047] Coupled with the setting of the switch protection frame, the possibility of human damage is greatly reduced.

[0048] The adjustable cleaning spray gun has a simple structure, most of which are machined parts, are easy to manufacture, more convenient to use, and has the characteristics of being beautiful and practical. It is widely used in various occasions where cleaning and watering are required.

[0049] It is worth mentioning that the technical features such as water supply equipment involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected by conventional methods in the field, and should not be regarded as the invention point of this utility model patent. This utility model patent will not be further elaborated.

[0050] For those skilled in the art, it is still possible to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
