Description

Technical Field

[0001] The present invention belongs to the technical field of cleaning machines, and particularly relates to a cleaning machine with a combination of a hard structure and a soft structure. Background Art

[0002] When cleaning equipment such as air conditioners, cleaning machines are often used. The cleaning machine generates water flow through a power device (water pump) and a nozzle to wash an object.

[0003] Existing cleaning machines for air conditioners mostly adopt small cleaning machines due to the low requirement for water pressure. Considering portability and ease of use, some are equipped with double shoulder straps or single shoulder straps. Such cleaning machines have the following problems: 1. The vast majority adopt an overall plastic structure. The plastic is relatively hard, resulting in poor portability and usage experience, and it is also inconvenient to add water; 2. A very small number adopt an overall soft package structure. It is not easy to fix components such as water pumps, batteries, and controllers, and they are easily damaged. Moreover, the water circuit and the electrical circuit are mixed (not completely isolated), posing a safety hazard. Summary of the Invention

[0004] Aiming at the deficiencies of existing cleaning machines that either adopt an overall plastic structure or an overall soft package structure, the present invention provides a cleaning machine with a combination of a hard structure and a soft structure, incorporating the advantages of both plastic and soft package structures. Further, the layout and related structures are optimized.

[0005] To achieve the above object, the present invention adopts the following technical solutions: A cleaning machine with a combination of a hard structure and a soft structure, including:

[0006] A main body of the combined hard and soft package, which includes a hard pump box base and a soft package. The lower end of the soft package is fixedly connected to the pump box base;

[0007] A pumping assembly, including a water pump, a battery, and a controller disposed in the pump box base;

[0008] A water bag, placed above the pump box base and located in the soft package;

[0009] A spray gun assembly, connected to the water pump;

[0010] Among them, the pump box base forms an isolation chamber, and the pumping assembly is located in the isolation chamber.

[0011] The cleaning machine with a combination of a hard structure and a soft structure of the present invention has a hard pump box base and a soft package. The pump box base forms an isolation chamber, and components such as the water pump, battery, and controller can be conveniently and reliably fixed in the isolation chamber, and the water circuit and the electrical circuit are isolated from each other, ensuring safe use; the soft package is more comfortable than the hard package, improving the portability experience.

[0012] As an improvement, the pump box base includes an upper cover and a bottom plate that are detachably connected. The space enclosed by the upper cover and the bottom plate forms an isolation chamber, and the lower end of the soft package is fixedly connected to the upper cover. With this structure, the water pump in the pump box base can be maintained by separating the upper cover and the bottom plate. In other solutions, the soft package can also be fixedly connected to the bottom plate.

[0114] See Figure 13 , in this embodiment, the upper cover 11 and the bottom plate 12 of the pump box base 1 are different from those in the first embodiment in that the height of the annular side wall of the bottom plate 12 is greater, and the height of the upper cover 11 is smaller. The bottom surface of the bottom plate 12 and the side surface facing the human body are smoothly transitioned, that is, the bottom of the pump box base 1 in contact with the human body is smooth, improving the comfort. The upper cover 11 and the bottom plate 12 jointly form a partition 13.

[0115] See Figure 14 , in this embodiment, the second group of spray gun assemblies includes an extension pipe 53. One end of the extension pipe 53 is a third quick-connect fitting 25, and the other end is a fourth quick-connect fitting 52. The fourth quick-connect fitting 52 is provided on the spray gun. The extension pipe 53 is connected to the third quick-connect fitting 25 connecting the water pump 21 through the fourth quick-connect fitting 52 thereon, and is connected to the fourth quick-connect fitting 52 on the spray gun through the third quick-connect fitting 25 thereon.

[0116] In this embodiment, the second group of spray gun assemblies 5 includes a flexible nozzle 56. The flexible nozzle 56 includes a flexible pipe that can be bent.

[0117] In this embodiment, the second group of spray gun assemblies 5 includes a spray gun extension rod 54.

[0118] In other embodiments, the flexible bag 3 includes a first part and a second part that are detachably connected, and the first part is fixedly connected to the pump box base 1. The detachable connection between the first part and the second part can be achieved by means of a high-strength zipper, a buckle, etc. The height dimension of the first part is relatively small. Dividing the flexible bag 3 into the upper and lower detachable first part and second part facilitates disassembling and cleaning the flexible bag 3.

[0119] In other embodiments, the lower end of the flexible bag 3 is located between the upper cover 11 and the bottom plate 12, and the screws fix the flexible bag 3 to the upper cover 11 and the bottom plate 12 while connecting the upper cover 11 and the bottom plate 12.

[0120] As described above, the above are only the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the content described in the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
