[0023] The motor 18 is used to pull the winding roller 15 to rotate, so that the winding roller 15 winds up the filter 17, forcing the original filter 17 above the first fixed ring 10 to move its position, and the new filter 17 is re-attached above the first fixed ring 10 to complete the position change of the filter 17. In this way, the vacuum cleaner can better isolate impurities inside the dust collecting bucket 1 while keeping the exhaust unobstructed.

[0024] The tensioning assembly includes two springs 11 arranged vertically, and both ends of the springs 11 are fixed with fixing blocks 12, and an adjusting tube 9 is fixed between the upper two fixing blocks 12, and the adjusting tube 9 is slidably plugged into the top of the first gas pipeline 7, and a first fixing ring 10 is fixed to the top of the adjusting tube 9, and the filter screen 17 is tightly fitted with the first fixing ring 10, and the lower fixing block 12 is fixedly installed on the first gas pipeline 7;

[0025] The exhaust assembly includes a barrel cover 23, on which a plurality of lock buckles 24 are provided, and the plurality of lock buckles 24 are used to lock the dust collecting barrel 1 and the barrel cover 23. A fan is provided inside the barrel cover 23, and an exhaust hole is provided on the barrel cover 23.

[0026] The second fixing ring 27 in the exhaust assembly is used to press down the first fixing ring 10, so that the spring 11 is in a contracted state. In this way, the filter screen 17 located between the first fixing ring 10 and the second fixing ring 27 can be clamped to a certain extent to ensure its stability during use. The application of the two springs 11 can enhance the tightness of the connection between the first fixing ring 10, the filter screen 17 and the second fixing ring 27, so that when the exhaust assembly draws air out of the dust bucket 1, the filter screen 17 can better filter the exhausted air.

[0027] A limit block 19 is fixed inside the bottom of the first gas pipe 7, and a float 20 is arranged inside the first gas pipe 7. The float 20 is located above the limit block 19, and the outer diameter of the float 20 is smaller than the inner diameter of the first gas pipe 7 and larger than the inner diameter of the regulating pipe 9;

[0028] The continuous accumulation of accumulated water will cause the float 20 to float up. After the float 20 floats up a certain distance, it will block the regulating pipe 9, making it impossible for the exhaust component to exhaust. At this time, the worker can stop the fan and switch to the sewage pump 21 to drain the water and then perform cleaning operations.

[0029] The sewage discharge assembly includes a sewage pump 21, which is fixedly installed inside the dust collecting bucket 1, and the sewage discharge port of the sewage pump 21 is fixedly connected to a sewage discharge pipe 22, and the other end of the sewage discharge pipe 22 extends to the outside of the dust collecting bucket 1;

[0031] Working principle of this utility model:

[0032] The filter bag 5 is then removed from the dust collection container 1 and the dust collection container 1 is then removed from the dust collection container 1. The filter bag 5 is removed from the dust collection container 1 and the dust collection container 1 is then removed from the dust collection container 1. The dust collection container 1 is then removed from the dust collection container 1 and the dust collection container 1 is then removed from the dust collection container 1.

[0033] When the vacuum cleaner is only sucking dust, the impurities are intercepted by the filter 17, so that the impurities are trapped inside the dust collecting bucket 1, and the clean air is discharged by the fan. The filter holes of the filter 17 are easily blocked due to the long-term interception of impurities, resulting in a decrease in the exhaust efficiency of the fan, affecting the suction force of the sewage inlet pipe 3. At this time, the motor 18 can be controlled to pull the winding roller 15 to rotate, so that the winding roller 15 winds up the filter 17, forcing the original filter 17 above the first fixing ring 10 to move its position, and the new filter 17 is re-attached above the first fixing ring 10. In this way, the vacuum cleaner can maintain good suction and better complete the cleaning operation.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
