Description

Technical Field

[0001] This utility model relates to the field of household cleaning equipment technology, and more specifically to a cleaning machine. Background Technology

[0002] Carpets are a common household item in many homes and offices. While they are comfortable and aesthetically pleasing, neglecting to clean them regularly can lead to bacterial growth, which is detrimental to health. The traditional method involves sending carpets to specialized cleaning services for washing and drying. However, this is time-consuming and labor-intensive, and the cleaning equipment used is quite large, requiring the entire carpet to be placed inside the agitator, which is inconvenient. Furthermore, it is ineffective for cleaning and drying only a small portion of the carpet, resulting in poor overall performance.

[0003] A carpet cleaning machine effectively solves the aforementioned problems. It sprays clean water to clean soiled areas and uses negative pressure suction to draw in dirty water and small dust particles, achieving spot cleaning and gaining widespread popularity. A carpet cleaning machine includes a cleaning solution storage tank, a water pump, a suction assembly, a wastewater tank, and a floor brush assembly. During use, the water pump draws the cleaning solution from the storage tank and delivers it through pipes to the nozzles. The nozzles evenly spray the cleaning solution onto the carpet surface. The surfactants and other components in the cleaning solution reduce the surface tension between dirt and carpet fibers, making it easier for dirt to detach from the fibers. After the cleaning solution is sprayed onto the carpet, the machine's vacuum suction system immediately activates, sucking away the cleaning solution and water containing dirt. The vacuum suction force is usually quite strong, reaching deep into the carpet fibers to thoroughly remove deeply hidden dirt and moisture.

[0004] Existing cleaning machines still have some shortcomings that need improvement during use: During wastewater recovery, the suction component draws the wastewater into a wastewater tank, where it remains. Gas exits the tank and is then discharged through the suction component before being expelled from the machine. This process involves the motor. However, because the wastewater in the tank contains dust and fine particles, some of these particles can be sucked into the motor's channels. Accumulation of these particles can damage the motor, consequently damaging the cleaning machine and reducing its lifespan. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a cleaning machine that can effectively prevent dust and particulate matter from being carried into the motor by the gas passing through the sewage tank, thereby extending the service life of the motor and, consequently, the service life of the cleaning machine.

[0006] The technical solution of this utility model is to provide a cleaning machine, including a main unit and a wastewater tank. The wastewater tank is installed on the main unit and includes a tank body and a lid. The lid covers the open end of the tank body, forming a wastewater cavity between the tank body and the lid. The lid has a cavity inside, and the cavity wall has an air inlet connected to the wastewater cavity. The bottom wall of the cavity has an installation groove connected to the cavity. The installation groove has a filter, and the bottom of the installation groove has an air outlet. When the cleaning machine is working, the gas in the wastewater cavity enters the cavity through the air inlet, is filtered by the filter, and is discharged through the air outlet.

[0007] With the above structure, the cleaning machine of this utility model has the following advantages compared with the prior art:

[0008] Because the bottom wall of the cavity of the cleaning machine of this utility model is provided with an installation groove and a filter is provided in the installation groove, when the cleaning machine is working, the gas in the sewage cavity enters the cavity through the air inlet, is filtered by the filter and discharged from the air outlet. The filter will filter out the dust and particles in the gas, making the gas discharged from the air outlet cleaner. This can effectively prevent dust and particles from being brought into the motor, thereby extending the service life of the motor and thus extending the service life of the cleaning machine.

[0009] As an improvement, the filter includes a filter element and a support. The filter element is detachably mounted on the support, and the shape of the support matches the shape of the mounting groove. The support is detachably mounted within the mounting groove.

The floor brush assembly 4 is installed at the lower end of the main unit 1 and is used to scrub carpets, floors, and other surfaces requiring cleaning. The cleaning fluid storage tank 2 is detachably installed on the main unit 1 and mainly houses the water pump and cleaning fluid spray pipes. The water pump sprays the cleaning fluid from the storage tank 2 onto the surfaces requiring cleaning, such as carpets or floors. The wastewater tank 3 is detachably installed on the main unit 1, and the suction assembly is installed inside the main unit 1. The suction assembly is used to draw the wastewater from the floor brush assembly 4 into the wastewater tank 3.

[0027] When the cleaning machine is in use, the water pump draws the cleaning solution from the storage tank and delivers it to the nozzles through pipes. The nozzles then spray the cleaning solution evenly onto the carpet surface. The surfactants and other components in the cleaning solution reduce the surface tension between dirt and carpet fibers, making it easier for dirt to detach from the fibers. After the cleaning solution is sprayed onto the carpet, the suction unit immediately activates, sucking away the cleaning solution and water containing dirt. The vacuum suction force is usually strong, reaching deep into the roots of the carpet fibers to thoroughly remove deeply hidden dirt and moisture.
