Description

A handheld cleaning machine Technical Field

[0001] This utility model relates to a cleaning machine for cleaning dirt from the surface of items, namely a handheld cleaning machine. Background Technology

[0002] Currently, dirt adhering to the surface of fabric sofas and other items can be removed using a handheld washer. The specific process is as follows: first, wet the dirt with water and use a cleaning brush to brush away the dirt from the surface of the item, creating wastewater. Then, start the handheld electric washer and aim the suction port at the wastewater, which will be sucked into the wastewater tank of the handheld electric washer for temporary storage. Traditional handheld washer brushes are directly mounted on the bottom of the wastewater tank and cannot be driven, meaning the brushes have a fixed installation structure. Therefore, the user needs to move the handheld washer back and forth quickly to help the brushes remove dirt from the surface of the item. Since handheld washers have a certain weight, continuous brushing during this process can cause wrist fatigue, affecting user comfort. Especially for some stubborn dirt, it is difficult to effectively remove the dirt by relying solely on the frequency of manual brushing, which also greatly affects the cleaning effect of the handheld washer. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a handheld cleaning machine that is easy and labor-saving to operate, comfortable to use, and has a good cleaning effect.

[0004] The technical problem of this utility model is solved by the following technical solution:

[0005] A handheld cleaning machine includes a body and a wastewater tank mounted on the body. The body contains a vacuum motor that is sealed to the wastewater tank via a suction channel and provides vacuum negative pressure. The body also contains a drive motor. The wastewater tank has an independently arranged mounting cavity and a reduction gear set enclosed within the mounting cavity. The bottom surface of the wastewater tank is provided with a cleaning brush. The drive motor drives the reduction gear set, which in turn drives the cleaning brush to rotate and clean.

[0024] A handheld cleaning machine, as shown in Figures 1 to 5, mainly relates to a small cleaning appliance used to clean and remove dirt adhering to the surface of items such as fabric sofas. Its structure includes a body 1 and a wastewater tank 2 that is detachably snapped onto the bottom of the body. That is, the entire cleaning machine adopts an upper and lower separated structure design, which ensures that there is sufficient installation space inside the body 1 and allows the wastewater tank 2 to be designed with a larger storage volume. The wastewater tank 2 is also equipped with a press-type disassembly button 23 to facilitate the disassembly and assembly of the wastewater tank 2 from the bottom of the body 1.

[0025] The body 1 is equipped with a battery pack 6, a vacuum motor 5 and a drive motor 4. The battery pack is a rechargeable battery pack to power the vacuum motor 5 and the drive motor 4. A switch 7 is provided on the front side of the body 1, that is, the left side of the body shown in Figure 1, which can be used to control the opening and closing of the vacuum motor 5 and the drive motor 4.

[0026] The machine body 1 has multiple exhaust holes 12 on both sides for exhausting the vacuum motor 5 when it is working. The vacuum motor 5 can be sealed and connected to the sewage tank 2 through a U-shaped suction channel 11 inside the machine body 1, thereby providing a vacuum negative pressure inside the sewage tank.

[0027] The sewage tank 2 consists of a tank body 21 and a detachable sealing cover 22 that is attached to the top of the tank body. The detachable fastening installation of the sewage tank 2 at the bottom of the machine body 1 is actually achieved by the tank body 21 being detachably fastened to the bottom of the machine body, and the cover 22 is hidden inside. Therefore, the cover 22 can only be opened and the sewage in the tank body 21 can be poured out by removing the sewage tank 2 from the bottom of the machine body.

[0028] The housing 21 has an independently arranged mounting cavity 213 and a reduction gear set 9 enclosed in the mounting cavity. The input axis of the reduction gear set extends upward through the top surface of the sewage tank 2 to install ratchet 91, specifically by exposing the ratchet in the top hole 221 of the tank cover 22. The output axis of the reduction gear set 9 extends downward through the bottom surface of the sewage tank 2 to install a cleaning brush 8. Specifically, the bottom surface of the housing 21 has a mounting groove 215, and the cleaning brush 8 is rotatably fitted into the mounting groove 215.

[0029] Meanwhile, the motor shaft of the drive motor 4 extends downward through the bottom surface of the body 1 to install the drive gear 41. In this way, when the sewage tank 2 is fastened and installed at the bottom of the body 1, the drive gear 41 will mesh with the ratchet 91 to form a power transmission. The power of the drive motor 4 will then drive the cleaning brush 8 to rotate in the mounting groove 215 after passing through the drive gear 41, the ratchet 91, and the reduction gear set 9. The cleaning brush 8 and the mounting groove 215 are usually designed to be circular for easy rotation. When the sewage tank 2 is detached from the bottom of the body 1, it can also drive the ratchet 91 to disengage from the drive gear 41, thereby avoiding affecting the disassembly of the sewage tank 2 and the body 1.

[0030] Obviously, by separating the drive motor 4 and the cleaning brush 8, and designing the reduction gear set 9, which serves as the power transmission, inside the wastewater tank 2, and installing ratchet 91 on the top surface of the wastewater tank, the wastewater tank 2 can be removed from the bottom of the body 1 along with the reduction gear set 9, ratchet 91, and cleaning brush 8 for wastewater cleaning. Alternatively, the wastewater tank 2 can be snapped onto the bottom of the body 1, and the ratchet 91 can engage with the drive teeth 41 of the drive motor 4 to form a power transmission, thereby ensuring that the drive motor 4 can reliably drive the cleaning brush 8 to rotate and clean.

[0031] The mounting cavity 213 is located in the middle of the housing 21. The housing also has a front partition cavity 211 and a rear partition cavity 212 located at both ends of the mounting cavity. The mounting cavity has a connecting channel 214 on both sides, and the connecting channel on each side connects to the front partition cavity 211 and the rear partition cavity 212 respectively.

[0032] The front side of the box 21 is provided with a suction pipe 3, which is a flat pipe. The lower end of the suction pipe 3 extends obliquely downward and is provided with a suction port 31. The position of the suction port is preferably lower than the bottom surface of the box 21, so that the suction port 31 can easily fit the dirt on the surface of the item for better suction. The upper end of the suction pipe 3 is directly connected to the front partition chamber 211 and is provided with a one-way valve. The vacuum motor 5 is sealed and connected to the rear partition chamber 212 through the air intake channel 11. The purpose of this structure is to prevent sewage from being accidentally sucked into the vacuum motor 5 and to allow sewage to be stored stably in the sewage tank 2. The box 21 can be made of transparent material so that users can observe the sewage storage status inside in real time.

[0033] The cover 22 is provided with positioning posts 223 and positioning grooves 222, which can be used to assist in the positioning and fastening installation of the sewage tank 2 at the bottom of the body 1. The cover 22 and the top of the body 21 together form a fastening groove 24, which is intended to enable the sewage tank 2 to be fastened to the bottom of the body 1 more quickly and accurately through the fastening groove 24 on the top of the body 1 when it is installed.

[0034] The working process of this utility model is as follows: First, wet the dirt on the surface of the item with clean water, then place the cleaning brush 8 on the bottom of the box 21 on the dirt, and drive the cleaning brush 8 to rotate at high speed by starting the drive motor 4, thereby brushing away the dirt and forming sewage. Then, after aligning the suction port 31 with the sewage, the sewage can be sucked into the sewage tank 2 for temporary storage by the vacuum negative pressure provided by the vacuum motor 5. Therefore, the whole operation process is easy and labor-saving, which not only ensures the comfort of the user, but also achieves a good cleaning effect.

[0035] The embodiments described above are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
