[0031] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0032] The terms “left,” “right,” “front,” “back,” “up,” and “down” mentioned in the following description are oriented in the viewing direction of the front view.

[0033] Example 1: In some embodiments, please refer to the accompanying drawings of the specification. Figure 1-Figure 7 , an electric plunger pump cleaning sprayer, comprising a housing 1,

[0034] The housing 1 is provided with a water storage device 2 for storing water and a cleaning device 3 for spraying water mist, and the water storage device 2 is connected to the cleaning device 3;

[0035] The cleaning device 3 includes a driving component 31 for driving the equipment, a spray component 32 for spraying water mist, and a fixing component 33 for placing the spray component 32. The driving component 31 and the spray component 32 are installed between the outer shell 1 and the water storage device 2. The driving component 31 is connected to the outer shell 1 and the spray component 32, the spray component 32 is connected to the outer shell 1 and the water storage device 2, and the fixing component 33 is connected to the outside of the water storage device 2.

[0036] When the electric plunger pump cleaning sprayer is in normal use, the driving component 31 drives the spray component 32 to extract water from the water storage device 2 and spray it out for cleaning. After the cleaning is completed, the components of the spray component 32 are fixed by the fixing component 33 to avoid damage. By arranging the heavier components of the spray component 32 inside the outer shell 1 and the water storage device 2, the weight of the handheld part of the staff is reduced, thereby reducing the difficulty of work.

[0037] The outer shell 1 includes a wheel component 11, a shell 12 and a handle 13. The wheel component 11 consists of two wheels and a connecting shaft. The wheels are fixedly mounted at both ends of the connecting shaft. The connecting shaft of the wheel component 11 is mounted at the rear end of the water storage device 2. The shell 12 is connected to the rear end of the water storage device 2. The handle 13 is connected to the upper end of the water storage device 2. The shell 12 is connected to the drive assembly 31 and the spray assembly 32.

[0038] The water storage device 2 includes a water tank 21 and a water tank cover 22. The connecting shaft of the wheel component 11 is rotatably connected to the rear end of the water tank 21. The shell 12 is fixedly installed at the rear end of the water tank 21. The two ends of the handle 13 are fixedly installed on both sides of the upper end of the water tank 21. The water tank cover 22 is fixedly installed on the upper end of the water tank 21 by threads. The rear end of the water tank 21 is connected to the spray assembly 32, and the outer side of the water tank 21 is connected to the fixed assembly 33. A water outlet is opened at the lower end of the water tank 21.

[0039] When the electric plunger pump cleaning sprayer is in normal use, the water tank cover 22 is opened to transport water into the water tank 21 for subsequent cleaning work. When the cleaning work is completed, the remaining water in the water tank 21 is released through the water outlet to reduce the overall weight. The water tank 21 is moved by pulling the handle 13, and the water tank 21 drives the wheel component 11 to rotate, so that the equipment can be moved conveniently.

[0040] The driving assembly 31 includes a battery 311, a battery bracket 312 and a battery cover 313. The battery 311 is fixedly installed on the inside of the battery bracket 312, the battery bracket 312 is fixedly installed on the inside of the shell 12, and the battery cover 313 is located at the rear end of the battery bracket 312. One end of the battery cover 313 is rotatably connected to the shell 12, and the other side of the battery cover 313 is clamped to the shell 12. The battery 311 is connected to the spray assembly 32.

[0041] The battery bracket 312 is fixedly connected to the housing 12 by bolts for easy disassembly.

[0042] The spray assembly 32 includes a plunger pump 321, a water outlet connector 322, a water pipe 323, a spray gun 324 and a nozzle 325. The plunger pump 321 is fixedly installed at the rear end of the water tank 21. The plunger pump 321 is electrically connected to the battery 311. The water inlet end of the plunger pump 321 is connected to the water tank 21 through a pipeline. The water outlet of the plunger pump 321 is fixedly connected to the water outlet connector 322. The water outlet connector 322 passes through the shell 12 and is connected and fixedly connected to one end of the water pipe 323. The other end of the water pipe 323 is connected and fixedly connected to the water inlet of the spray gun 324. The water outlet of the spray gun 324 is fixedly connected to the nozzle 325.

[0043] A micro switch is provided on the pump head of the plunger pump 321 , and the water outlet of the plunger pump 321 is threadedly connected to the water outlet connector 322 , and one end of the water outlet connector 322 is configured to be rotatable and retractable to adapt to water pumps of various sizes.

[0044] The fixing assembly 33 includes a fixing frame 331 and a placement tube 332. The fixing frame 331 is fixedly installed at the upper end of the outer side of the water tank 21. A through hole is provided on the fixing frame 331 to engage with the nozzle 325. The placement tube 332 is fixedly installed at the lower end of the outer side of the water tank 21. A through hole is provided at the bottom of the placement tube 332 for water leakage.

[0045] When the electric plunger pump cleaning sprayer is in normal use and the battery 311 needs to be replaced, the battery cover 313 can be opened, the fixing bolts of the battery holder 312 can be loosened to disassemble the battery holder 312, and the battery 311 can be replaced. When the equipment is running, the plunger pump 321 is turned on, and the plunger pump 321 transports the water in the water tank 21 to the water pipe 323 through the water outlet connector 322. The switch of the spray gun 324 is pressed, and the water forms a water mist through the nozzle 325 and is sprayed out for cleaning. After cleaning is completed, the switch of the spray gun 324 is turned off, and the plunger pump 321 is turned off by the microswitch on the plunger pump 321. The nozzle 325 is placed in the placement tube 332 away from the end of the spray gun 324, and the nozzle 325 is placed close to the nozzle 325. One end of the spray gun 324 is snap-connected to the fixing bracket 331, and the remaining water in the nozzle 325 flows into the placement tube 332 and flows in through the bottom through hole in the placement tube 332 to avoid water accumulation. By fixing the plunger pump 321 on the water tank 21, the weight of the spray gun 324 is reduced and the difficulty of work is reduced. The outlet connector 322 is rotatable and retractable, so that the outlet connector 322 can be adapted to water pumps of various sizes. It is fixed by the bolts of the battery bracket 312, which is convenient for overall disassembly when replacing the battery 311. Through the setting of the micro switch, the plunger pump 321 is automatically turned off when the spray gun 324 is turned off, which reduces the workload and avoids the plunger pump 321 being in working state for a long time due to negligence of the staff.
