A spring latch 29 is provided on the side of the turntable 25; a filter pressure regulating valve 31 is provided inside the control box 3, and a compressed air solenoid valve 32 is provided at the output end of the filter pressure regulating valve 31. A wireless remote control receiver 33 is provided inside the control box 3. By providing a discharge hard pipe 24, the nozzle part of the handheld sprayer is convenient. The turntable 25 is rotatably connected to the nozzle base 26. A plurality of threaded connectors 27 are provided on the nozzle base 26 to facilitate the connection of a variety of different discharge nozzles 28. By deflecting the nozzle base 26, the discharge nozzle 28 to be used can be switched and selected, so that the sprayer can be adjusted according to the needs of use, thereby achieving the purpose of improving the convenience of using the sprayer.

[0022] Specifically, the output end of the air pump 1 is connected to the input end of the filter pressure regulating valve 31 in the control box 3 through an air guide pipe 11, and the output end of the air solenoid valve 32 is connected to the air delivery port 21 on the pneumatic diaphragm pump 2 through another air guide pipe 11.

[0023] In this embodiment, the air pump 1 delivers gas to the control box 3 through the air pipe 11, and the gas enters the pneumatic diaphragm pump 2 after passing through the filter pressure regulating valve 31 and the air solenoid valve 32, thereby driving the pneumatic diaphragm pump 2 to pump the pickling solution.

[0024] Specifically, the filter pressure regulating valve 31 and the air solenoid valve 32 are both electrically connected to the wireless remote control receiver 33 .

[0025] In this embodiment, by providing a wireless remote control receiver 33 , the control box 3 can receive wireless signals for remote control, thereby controlling the switch states of the filter pressure regulating valve 31 and the air solenoid valve 32 .

[0026] Specifically, two hand guards are provided at the front end of the discharge hard tube 24, and anti-slip grooves are provided on the surface of the discharge hard tube 24 between the two hand guards.

[0027] In this embodiment, during use, the staff mainly holds the discharge hard tube 24, and hand guards and anti-slip patterns are provided on the discharge hard tube 24 to prevent the discharge hard tube 24 from slipping out of the hands when wearing protective gloves.

[0028] Specifically, the turntable 25 is coaxially arranged with the nozzle base 26 , a mechanical seal is arranged between the nozzle base 26 and the turntable 25 , and the number of the discharge nozzles 28 is not less than two, and the discharge nozzles 28 are symmetrically arranged on the nozzle base 26 with the center of the nozzle base 26 as the center.

[0029] In this embodiment, during the rotation of the turntable 25, each discharge nozzle 28 is connected to the liquid outlet channel of the discharge hard tube 24 on the turntable 25 one by one, so that the discharge nozzle 28 on the output side of the discharge hard tube 24 is selected to facilitate the switching of the nozzle.

[0030] Specifically, the spring latch 29 is disposed away from the axis of the turntable 25 , one end of the spring latch 29 is plugged into the nozzle base 26 , and the other end of the spring latch 29 extends to the rear of the turntable 25 .

[0031] In this embodiment, the spring latch 29 is retracted inward under the action of the spring, thereby plugging into the nozzle base 26, fixing the relative angle between the nozzle base 26 and the turntable 25. When the nozzle base 26 needs to be deflected, the above-mentioned fixation is released by pulling the spring latch 29 outward.

[0032] When in use, the discharge nozzles 28 required in the cleaning process are threadedly connected to each threaded connector 27. When the air pump 1 is turned on, the gas enters the control box 3 through the air guide pipe 11. When it is necessary to work, an opening signal is sent to the wireless remote control receiver 33, and the filter pressure regulating valve 31 and the compressed air solenoid valve 32 are opened. The gas passes through the filter pressure regulating valve 31 and the compressed air solenoid valve 32 in turn to the gas delivery port 21, thereby driving the pneumatic diaphragm pump 2 to start working. The pickling liquid is input through the feed hose 22, and after being guided by the discharge hose 23 to the discharge hard pipe 24, it is sprayed out through the discharge nozzle 28 opposite to the discharge hard pipe 24. When it is necessary to switch the discharge nozzle 28, the spring latch 29 is pulled outward and the nozzle base 26 is deflected so that the required discharge nozzle 28 is facing the discharge hard pipe 24.

[0033] In summary, the pickling liquid sprayer is convenient for holding the nozzle part of the sprayer by setting the discharge hard pipe 24, setting the turntable 25 and the nozzle base 26 for rotation connection, and setting a plurality of threaded connectors 27 on the nozzle base 26 for convenient connection of a variety of different discharge nozzles 28. By deflecting the nozzle base 26, the discharge nozzle 28 to be used can be switched and selected, so that the sprayer can be adjusted according to the needs of use, thereby achieving the purpose of improving the convenience of using the sprayer.
