The control module 16 is electrically connected with the fluid driving element 15. The control module 16 may be, for example, a PCB control board integrated with electric components such as a single-chip microcomputer. The visual interface module is installed on the gun body and exposed on a surface of the gun body. The visual interface module may be, for example, a display screen 12 or an atmosphere light 13 that can represent different information in different lighting states or different colors.
The visual interface module is electrically connected with the control module 16. The switch assembly is electrically connected with the control module 16. The switch assembly at least includes an on-off switch 17 and a speed regulation switch 18. The battery pack is electrically connected with the control module 16. The control module 16 is configured to obtain power information of the battery pack and/or working state information of the fluid driving element 15, and display the power information of the battery pack and/or the working state information of the fluid driving element 15 through the visual interface module.
It may be understood that the visual interface module can display remaining power of the battery pack and a working state of the fluid driving element 15 in real time visual interface module. A user can reasonably set working power of the spray gun according to the remaining power and turn on a high-power mode when necessary, for example, to clean stubborn stains. This can reasonably distribute power of the battery pack, improve an endurance of the spray gun, and avoid battery replacement or charging in a middle of a process, and thus improving work efficiency.

In this embodiment, the control module 16 may, for example, use a following method to prompt power of the battery pack and a related working state of the spray gun: when the battery is inserted into the battery compartment, the display screen 12 lights up, and the atmosphere lights 13 on two sides flash; when a consumer needs a higher pressure for cleaning, a TURBO button on the display screen 12 (which means the speed regulation switch 18) may be pressed. At this time, a cleaning machine is in a strong working state, and the display screen 12 and the atmosphere lights 13 on the two sides display a green flashing state, which may last for 6-30 seconds. If the TURBO button is not pressed, the cleaning machine is in a standard working state, and the display screen 12 and the atmosphere lights 13 on the two sides display a green steady state. When battery power is lower than a set value, the display screen 12 and the atmosphere lights 13 on the two sides display a red steady state. When the cleaning machine fails, the display screen 12 and the atmosphere lights 13 on the two sides display a red flashing state.

The auxiliary agent container 24 is used to store cleaning auxiliary agent. According to Bernoulli's principle, when water flows at high speed in the gun barrel 21, a negative pressure will be generated in the right-angle tube 25. Therefore, when the auxiliary agent container 24 is communicated with the right-angle tube 25, the cleaning auxiliary agent in the auxiliary agent container 24 can be sucked into the first flow passage 2311, and the cleaning auxiliary agent is mixed with the water and then sprayed out from the spraying head 23.

In summary, the disclosure can display remaining power of the battery pack and a working state of the fluid driving element 15 in real time through the visual interface module. A user can reasonably set working power of the spray gun according to the remaining power and turn on a high-power mode when necessary, for example, to clean stubborn stains. This can reasonably distribute power of the battery pack, improve an endurance of the spray gun, and avoid battery replacement or charging in a middle of a process, and thus improving work efficiency.
The floating ring 101 can compensate for the assembly gap, improve a stability between the gun body assembly 10 and the gun head assembly 20, and enhance an appearance quality of the spray gun.
The disclosure places the auxiliary agent container 24 horizontally below the assembly of the gun barrel 21. The assembly direction of the auxiliary agent container 24 is toward the user. The user only needs to hold the gun handle with one hand and complete assembly operation of the auxiliary agent container with the other hand, which enables the operation to be simpler and more labor-saving.
Considering that during the assembly process of the cleaning tool, due to the influence of appearance factors, the gun body assemblies of the body are mostly connected by a buckle, and the display screen is generally fixed inside the gun body assembly. When rework is required, only the entire gun body assembly should be disassembled, which may easily cause the gun body assembly to be scrapped or the display screen to be damaged.

In summary, the disclosure adds the clamping ring 102 on the outside of the gun body assembly 10 and connects the clamping ring 102 with the body of the gun body assembly 10 through a buckle, so that the display screen 12 is pressed and installed onto the gun body assembly 10, thereby reducing the scrap rate of the gun body assembly 10 caused by the screen problems, shortening the rework time, and improving the assembly efficiency.
As one of the various accessories of the high-pressure cleaning machine, the multi-in-one spray nozzle (spraying rod) integrates the multiple spray nozzles and realizes the integration of multiple water shapes in one, allowing the customers to flexibly switch the cleaning modes according to the needs of different cleaning conditions. Considering that a water inlet position of the conventional multi-in-one spray nozzle on the market is located on one side of the central axis of the spraying head, the overall shape is asymmetrical. When adjusting the spraying head, a force on the spraying rod is uneven. And conventional multi-in-one spray rods on the market are limited by functional requirements, and a rod body material is usually nylon fiberglass. Its manufacturing process cannot meet higher appearance design requirements, such as mirror highlights, colored parts, etc. One or more embodiments of the disclosure provide the gun head assembly and a spraying rod assembly, both of the gun head assembly and the spraying rod assembly are with symmetrical overall appearances and convenient for spray nozzle adjustment.

In a specific embodiment, the first flow passage 2311 is the blind hole formed along the center of the fixing component 231, and the second flow passage 2312 is another blind hole eccentrically arranged relative to the first flow passage 2311. The two blind holes may be communicated with each other through the radial hole, for example. For ease of manufacturing, the radial hole may, for example, penetrate a side wall of the fixing component 231, and then a plug 2334 is arranged at an opening of the radial hole.
In a specific embodiment, the fixing component 231 may be integrally formed with the gun barrel 21, or it may be separately processed and assembled into one, for example, the fixing component 231 is connected with the gun barrel 21 by the threaded connection.

In summary, the axis of the gun head assembly 20 in the disclosure is arranged colinearly with the axis of the gun barrel 21, and the water flow is guided to the position corresponding to the spray nozzle 234 through the eccentrically arranged second flow passage, thereby realizing the symmetrical design of the gun head assembly 20 relative to the gun barrel 21, and meeting the different industrial styling requirements, and when switching the spray nozzle 234, the adjustment device can be rotated along the axis of the gun barrel 21, which enables the adjustment to be more convenient.
Considering that the cleaning machine needs to replace different cleaning accessories according to different cleaning conditions, cleaning accessories are generally installed at a front end of the high-pressure water gun of the cleaning machine. In the conventional art, when the cleaning accessory is connected with the high-pressure water gun of the cleaning machine, an assembly gap is often generated. An existence of the assembly gap will cause the cleaning accessory and the high-pressure water gun to be loosely connected with each other, which is prone to shaking. In addition, there is usually an obvious discontinuity or gap at the appearance connection between the cleaning accessory and the high-pressure water gun, which affects the appearance of the machine. The disclosure further provides a connecting device and the spray gun that can reduce the assembly gap.

In summary, the elastic element 1011 of the disclosure causes the first connecting part and the second connecting part to have the tendency to be separated from each other, while the first limiting part and the second limiting part can prevent the separation of the first connecting part and the second connecting part. Therefore, there will always be the certain internal stress between the first connecting part and the second connecting part, and this internal stress may enable the two components fit as closely as possible, reduce the error caused by assembly, and prevent looseness between the gun head assembly 20 and the gun body assembly 10. The floating ring 101 can eliminate cracks on the surface of the connecting part between the gun body assembly 10 and the gun head assembly 20. As the floating part, the floating ring 101 can always maintain the fit with the first connecting part and the second connecting part, which is equivalent to filling the gap between the first connecting part and the second connecting part, ensuring that the connecting part has the complete and continuous appearance shape, thereby improving an appearance quality of the product.
Considering that when the spray gun sprays water, some cleaning auxiliary agent is often necessary to be added at the same time, such as soap solution, the cleaning auxiliary agent is stored in a container and communicated with the water outlet tube of the water gun through a pipeline. When the water flows at a high speed, the cleaning auxiliary agent can be sucked from the container into the water outlet tube through negative pressure and mixed with the water. At present, the soap dispensers on the market are all vertically installed on the gun barrel, which results in a relatively simple overall style of the product, restricts the shape design of the product, and the assembly process of the conventional soap dispensers is cumbersome and inconvenient to replace. One or more embodiments of the disclosure further provide an auxiliary agent container mounting structure for the spray gun which can be installed horizontally and has a simple and efficient assembly process.

In summary, the disclosure places the auxiliary agent container 24 horizontally under the gun head assembly 20, and connects the auxiliary agent container 24 with an outer housing 22 of the gun head assembly 20 through the first connecting part and the second connecting part. The assembly direction of the auxiliary agent container is toward the user. The user only needs to hold the gun handle with one hand and complete assembly operation of the auxiliary agent container 24 with the other hand, which enables the operation to be simpler and more labor-saving. The disclosure arranges a series of limiting structures and sealing structures to ensure that the auxiliary agent container 24 is tightly connected with the gun head assembly 20 to avoid a leakage of cleaning auxiliary agent.
Considering that during an operation of the lithium battery cleaning machine, since the operating power is relatively large while ensuring the pressure and flow, the battery capacity is limited, and the use time is relatively short. However, in actual use, high power is not required all the time, and higher pressure is only required when cleaning stubborn stains. However, the spray guns in the conventional art lack information interaction functions, and users cannot obtain information such as the power information, operation state and faults of the spray guns, resulting in an inability to reasonably configure the operating power of the spray guns according to actual usage conditions, resulting in a decrease in the battery life of the spray guns, which affects cleaning efficiency. One or more embodiments of the disclosure provide a control method of the spray gun and the spray gun that can display a working state of the spray gun in real time to reasonably configure operating power.

Considering that conventional battery pack compartments are widely arranged in portable tools, the battery pack compartment is mainly used to fix and protect the battery pack. The battery pack is detachably installed in the battery pack compartment to facilitate the replacement of the battery pack, so the battery pack compartment is generally equipped with a detachable compartment cover. Most battery pack compartments and compartment covers are assembled by a buckle. However, the buckle assembly is limited by space and the buckle can be easily broken, causing the entire structure to fail. In addition, the locking force of the buckle is difficult to control. If the buckle is too tight, the disassembly and installation process will be more laborious. If the buckle is too loose, the compartment cover will become loose or even fall off. One or more embodiments of the disclosure provide the battery pack compartment and a cleaning tool that facilitates a disassembly and assembly of the battery pack.
