Description

A water-circulating fabric cleaning machine Technical Field

[0001] This invention relates to the technical field of fabric cleaning machines, and in particular to a water-circulating fabric cleaning machine. Background Technology

[0002] Homes often have many large fabric products, which are not practical to wash directly with water. However, not cleaning them can easily lead to dirt and grime buildup. Therefore, fabric cleaning machines have become popular in recent years. However, most fabric cleaning machines require changing the water after one tank of water is used up, which often has to be done several times. This is both troublesome and wasteful of water. Moreover, considering the area of ​​the fabric products to be cleaned, the cleaning machine needs to be large, which makes it inconvenient to use and place.

[0003] A multifunctional fabric cleaning machine, disclosed in Chinese Patent Publication No. CN117694804A with an authorization announcement date of March 15, 2024, includes a main body, a base, a wastewater tank, a clean water tank, cleaning components, and a connecting pipe. The wastewater tank contains an air inlet pipe, an air outlet pipe, a water level float, and a filter assembly. Openings are provided at the top of the air inlet and outlet pipes. The connecting pipe is mounted on the base and connects the cleaning handle to the air inlet pipe. The water level float and filter assembly are located at the top of the air outlet pipe. The water level float limits the maximum water level in the wastewater tank, and the filter assembly prevents hair or dust from entering the air outlet pipe. The water level float and filter assembly are interchangeable. The cleaning components include a first cleaning brush head, a second cleaning brush head, a first flexible hose, and a connector. The connector engages with the connecting pipe, and the first and second cleaning brush heads are interchangeable via the connector. This invention solves the problem of not being able to directly suck up hair and dust from fabrics through filter cotton and replaceable cleaning brush heads. The drawback of this invention is that it requires frequent water changes, and its size makes it inconvenient to use and place. Summary of the Invention

The sealing ring 31 is also integrally formed with the one-way outlet valve 17 and surrounds the outer surface of the one-way outlet valve 17, and is engaged with the one-way outlet valve 17 by the retaining ring 32. The sealing ring 31 is wider in the middle and gradually narrows towards both ends. The spring 30 is also integrally formed with the sealing ring 31 and the other end of the spring 30.

[0033] As shown in Figures 1 and 2, both the clean water tank 2 and the wastewater tank 1 are equipped with handles 33, which are rotatably connected to the clean water tank 2 and the wastewater tank 1, respectively.

[0034] As shown in Figure 1, a handle 34 is provided on the upper cover 4 of the machine body. The handle 34 is fixedly connected to the upper cover 4 of the machine body. The clean water tank 2 and the wastewater tank 1 are respectively placed on the left and right sides of the handle 34.

[0035] For initial preparation, fill the clean water tank 2 with water and then install it onto the machine body cover 4 using handle 33. Simultaneously, install the wastewater tank 1 onto the machine body cover 4 using handle 33 as well. Connect the wastewater pump 5 through the end of the connecting water pipe 9 with the water connector 13, passing it through the wastewater tank cover 14 and connecting it to the recycling bucket water connection valve 12 on the slot 26 in the inner cover 11 of the wastewater tank. Then, insert the end of the connecting water pipe 9 with the water connector 16 into the slot 27, where it contacts the one-way outlet valve 17, thus connecting to the clean water tank 2. Then, using handle 234, fix the upper cover 4 of the machine body, which has a wastewater tank 1 and a clean water tank 2, to the base 3 of the machine body. In use, first use the water pump 15 to spray the clean water in the clean water tank 2 through the clean water tank outlet 18 onto the fabric product that needs cleaning. The one-way water valve 17 at the clean water tank outlet 18 ensures unidirectional water flow. Then, turn on the main switch 8, allowing the suction motor 6 to draw the cleaned wastewater through the suction pipe 7 into the wastewater tank 1 via the suction generated by the air outlet 35. Next, turn on the water pump switch 10 to start the wastewater pump 5, allowing the wastewater to flow smoothly. The water first passes through filter cotton 23 to remove foam, filter 22 to remove large particles and fine impurities such as dust, and the sealing gasket 21 facilitates the installation and fixation of filter 22. The resulting clean water flows from the wastewater inlet pipe 19 of the recycling bin, through the water rod 24, the second connecting water pipe 25, and the water connection valve 12 of the recycling bin to the wastewater tank 1. It then passes through a first connecting water pipe 9, the wastewater pump 5, and another first connecting water pipe 9 to reach the clean water tank 2. When the filtered water passes through the one-way outlet valve 17, the retainer 29 on the one-way outlet valve 17 receives the water. The water moves within the through hole 28 due to the force of the action of the spring 30, while the retaining end 29 ensures that the one-way water outlet valve 17 does not disengage from the retaining groove 27. The spring 30 allows the sealing ring 31 to move. At this time, the spring 30 is compressed, and water enters the clean water tank 2 from the through hole 28. When the sewage pump 5 stops working, the spring 30 is released, thereby driving the one-way water outlet valve 17 to reset. The retaining ring 32 on the one-way water outlet valve 17 drives the sealing ring 31 to move towards the through hole 28 until the through hole 28 is sealed. In this way, the sealing ring 31 can block the through hole 28 to prevent water flow from crossing when the water flow is reversed. In this way, the water in the cleaning machine can be reused and circulated multiple times. Moreover, the clean water tank 2 and the sewage tank 1 are installed on the machine body cover 4 as a whole and can be taken out and used as a whole with the handle 2 34. It is convenient to use, the water is recycled, and the area of ​​the water tank can be reduced, which can save space and facilitate placement. It achieves the purpose of water recycling and is more convenient to use and place.
