Description

Technical Field

[0001] The utility model relates to the technical field related to a clean water tank for a handheld fabric cleaning machine, in particular to a clean water tank assembly for a handheld fabric cleaning machine. Background Art

[0002] Handheld cleaning machines can clean carpets, fabric sofas, curtains and other fabric products. The cleaning process usually involves spraying cleaning fluid or clean water containing detergent onto the surface of the fabric product. After the surface of the fabric product is moistened, the user activates the negative pressure component. The suction port of the fabric cleaning machine absorbs water stains and dirt on the surface of the fabric product into the sewage tank. The gas-liquid separator in the sewage tank separates the sewage and gas, so that the sewage is retained in the sewage tank and the gas is discharged, thereby realizing the cleaning and sewage collection process.

[0003] The Chinese patent number is CN116135108A, and the publication date is May 19, 2023. It discloses a handheld suction cleaner, a unit body, the unit body includes a carrying handle, a first lateral side and a second lateral side; a fluid delivery system, the fluid delivery system includes a supply tank and at least one fluid dispenser carried by the unit body; and a recovery system, the recovery system includes: a working air path, passing through the unit body; a suction nozzle, defining an inlet leading to the working air path; a suction source, fluidly connected to the suction nozzle, and a recovery tank, carried by the unit body, the recovery tank includes: a collection chamber; an inlet opening leading to the collection chamber; and a tank body, defining the collection chamber, the tank body having a first side and a second side, wherein the first side of the recovery tank is laterally arranged outward relative to the first lateral side of the unit body, and the second side of the recovery tank is laterally arranged outward relative to the second lateral side of the unit body.

[0004] The supply tank comprises a blow molded tank body defining a supply chamber and an openable filling cap covering a filling opening of the tank body, wherein the filling cap is openable to refill the supply chamber when the tank body is located on the unit body. The tank body cannot be removed from the unit body.

[0005] It can be seen from the above patent that the tank body of the supply tank (i.e., the clean water tank) is fixedly connected to the unit body (equivalent to the cleaning machine body) and cannot be removed. When the cleaning liquid needs to be injected into the supply tank, the operator can only transfer the supply tank together with the unit body to the corresponding position for processing, which is time-consuming, labor-intensive, and inconvenient to operate. During the injection process, the risk of water entering the unit body is easily increased, which is not conducive to extending the service life of the equipment. In addition, it is not convenient to clean and maintain the supply tank. Utility Model Content
