[0024] A handheld cleaning machine, as shown in Figures 1-5 , mainly relates to a small cleaning appliance for cleaning and removing dirt adhered to the surface of cloth sofas and other objects, which comprises a machine body 1 and a sewage tank 2 detachably and buckleably mounted at the bottom of the machine body, that is, the whole cleaning machine adopts an upper-lower separation structure design, which not only ensures that the machine body 1 has sufficient installation space, but also enables the sewage tank 2 to be designed with a larger storage volume, and the sewage tank 2 is further provided with a press-type dismounting button 23 to facilitate the dismounting of the sewage tank 2 from the bottom of the machine body 1.

[0025] The machine body 1 is provided with a battery pack 6, a vacuum motor 5 and a driving motor 4, the battery pack can be a rechargeable battery pack to supply power to the vacuum motor 5 and the driving motor 4, and the left side of the machine body 1, that is, the left side of the machine body as shown in Figure 1 , is provided with a switch 7 for controlling the opening and closing of the vacuum motor 5 and the driving motor 4.

[0026] The machine body 1 is provided with a plurality of exhaust holes 12 on both sides for exhaust when the vacuum motor 5 is working, and the vacuum motor 5 is in sealed communication with the sewage tank 2 through a U-shaped air inlet channel 11 in the machine body 1, thereby providing a vacuum negative pressure in the sewage tank.

[0027] The sewage tank 2 is composed of a tank body 21 and a detachable tank cover 22 which is combined with the tank body on the top of the tank body 21. The detachable fastening installation of the sewage tank 2 on the bottom of the machine body 1 is actually realized by the detachable fastening installation of the tank body 21 on the bottom of the machine body and the hiding of the tank cover 22 inside. Therefore, only when the sewage tank 2 is detached from the bottom of the machine body 1, the tank cover 22 can be opened and the sewage in the tank body 21 can be poured out.

[0028] The tank body 21 is provided with an installation cavity 213 and a speed reduction gear set 9 which is arranged in the installation cavity. The input shaft of the speed reduction gear set 9 is installed with a ratchet 91 which penetrates the top surface of the sewage tank 2 and is exposed on the top hole 221 of the tank cover 22. The output shaft of the speed reduction gear set 9 is installed with a cleaning brush 8 which penetrates the bottom surface of the sewage tank 2 and is arranged in the installation groove 215 on the bottom surface of the tank body 21.

[0029] Meanwhile, the motor shaft of the driving motor 4 penetrates the bottom surface of the machine body 1 and is installed with a driving tooth 41. When the sewage tank 2 is fastened and installed on the bottom of the machine body 1, the driving tooth 41 is engaged with the ratchet 91 to form power transmission. The power of the driving motor 4 is transmitted to the cleaning brush 8 through the driving tooth 41, the ratchet 91 and the speed reduction gear set 9, and the cleaning brush 8 is rotated in the installation groove 215. The cleaning brush 8 and the installation groove 215 are usually circular to facilitate rotation. When the sewage tank 2 is separated from the bottom of the machine body 1, the ratchet 91 is also separated from the driving tooth 41, so as to avoid affecting the disassembly of the sewage tank 2 and the machine body 1.

[0030] Obviously, since the driving motor 4 and the cleaning brush 8 are designed separately, the speed reduction gear set 9 which is used for power transmission is designed in the sewage tank 2, and the ratchet 91 is installed on the top surface of the sewage tank. Therefore, the sewage tank 2 can be removed from the bottom of the machine body 1 together with the speed reduction gear set 9, the ratchet 91 and the cleaning brush 8 to clean the sewage. The sewage tank 2 can also be fastened and installed on the bottom of the machine body 1, and the ratchet 91 is engaged with the driving tooth 41 of the driving motor 4 to form power transmission, so as to ensure that the driving motor 4 can reliably drive the cleaning brush 8 to rotate and clean.

[0031] The installation cavity 213 is arranged in the middle of the tank body 21. The front partition cavity 211 and the rear partition cavity 212 are arranged in the tank body respectively at two ends of the installation cavity. The connection channels are arranged on both sides of the installation cavity respectively, and each connection channel respectively connects the front partition cavity 211 and the rear partition cavity 212.

[0032] The front side of the box 21 is provided with a dirt suction pipe 3, which is a flat pipe, and the lower end of the dirt suction pipe 3 extends obliquely downward and is provided with a dirt suction opening 31, and the position of the dirt suction opening is preferably lower than the bottom surface of the box 21, so that the dirt suction opening 31 can be conveniently attached to the dirt on the surface of the object to better perform dirt suction, and the upper end of the dirt suction pipe 3 is directly communicated with the front partition chamber 211 and is provided with a one-way valve, and the vacuum motor 5 is sealedly communicated with the rear partition chamber 212 through the air suction channel 11, and the design purpose of this structure is that the sewage cannot be accidentally sucked into the vacuum motor 5, and the sewage level can be stably stored in the sewage tank 2, and the box 21 can be made of transparent material, so that the user can observe the internal sewage storage condition in real time.

[0033] The box cover 22 is provided with a positioning column 223 and a positioning groove 222, which can be used for auxiliary positioning and buckling installation of the sewage tank 2 at the bottom of the machine body 1, and the box cover 22 and the top of the box 21 are further jointly surrounded to form a buckling groove 24, and the purpose is to enable the sewage tank 2 and the machine body 1 to be installed through the buckling groove 24 at the top of the box and the bottom of the machine body 1 to form more rapid and accurate buckling.

[0034] The working process of the utility model is as follows: the dirt on the surface of the object is first moistened with clean water, then the cleaning brush 8 at the bottom of the box 21 is placed on the dirt, and the cleaning brush 8 is driven to rotate at high speed by starting the driving motor 4, so that the dirt is brushed off to form sewage, then the dirt suction opening 31 is aligned with the sewage, and the sewage in the sewage tank 2 is sucked into the sewage tank 2 for temporary storage by providing vacuum negative pressure in the sewage tank 2 by the vacuum motor 5, so that the whole operation process is easy and labor-saving, which not only guarantees the comfort of the user, but also achieves good cleaning effect.

[0035] The above-described embodiments are only used to illustrate the utility model and not to limit the scope of the utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the appended claims of the present application.
