Description

Technical Field

[0001] This invention relates to the field of cleaning areas, and more particularly to a pulsator rod assembly for decontamination and its cleaning device. Background Technology

[0002] Most existing vacuum cleaners only have dry suction function. They cannot be used for sewage on the ground, otherwise the vacuum motor will be damaged.

[0003] Some manufacturers have developed cleaning devices with wet mopping functions, but these rely on a suction pump to draw wastewater and debris into a tank. This suction typically requires a very high power output, resulting in high power consumption and frequent charging, causing inconvenience and high operating costs for users. Furthermore, the suction nozzles or channels are prone to clogging, causing significant inconvenience. Additionally, wet mopping doesn't always remove all wastewater from the roller brush. To remove wastewater from the cleaned areas, the roller brush must be cleaned promptly; otherwise, wastewater will re-contact other areas during the brush's rotation, causing them to become dirty again. Adding clean water to the roller brush is also necessary to keep it clean and ensure more effective cleaning.

[0004] Therefore, this patent needs to provide a new technical solution to address the technical problem of how to remove sewage, replenish clean water, and prevent the clean water from being polluted by sewage. Summary of the Invention

In the present patent, the gap between the first thread group and the second thread group of the screw 41 and the inner wall of the screw shell 42 is less than 5mm, preferably less than 1mm, and more preferably 0.2-0.5mm. If the gap between the thread edge and the inner wall of the screw shell is too large, it will cause poor transmission effect of the screw rotation. If the gap between the thread edge and the inner wall of the screw shell is too small, for example, the thread edge is tangent to or in contact with the inner wall of the screw shell, the friction will be increased, and the transmission will also be affected.

The screw rotates in the screw shell and transports the sewage in the screw shell to the sewage outlet along the thread direction, and then transports the sewage to the sewage tank through the sewage channel. In the example, the screw shell 42 is a semi-enclosed structure, and the included angle of the screw shell 42 from one side of the inlet to the other side of the inlet is greater than 180 degrees. The sewage transmission mechanism formed by the semi-enclosed screw shell and the screw has a significant difference in transmission principle and transmission effect compared with the prior art, and the cost is relatively low, and the water pumping module is omitted.

[0100] Under the high-speed rotation of the screw and the screw blade, the sewage is centrifugally rotated to the sewage port of the screw shell, and is thrown into the sewage port by the water throwing blades.

Preferably, the disassembling component 23 is further provided with a second roller brush cover 235, which is arranged on the cover plate 2314, or arranged on the pressing member 233, or arranged on the button 234.

In the example, the transmission motor and the first roller brush cover are fixedly connected with the second end cover, and the transmission motor and the first roller brush cover are not taken out of the device body with the roller brush body, and the disassembling component and the flexible cleaning layer are taken out of the device body with the roller brush body.

[0125] The disassembling component is arranged to facilitate the roller brush assembly to be disassembled, cleaned or replaced at any time. As known, the surface of the roller brush assembly is particularly easy to be dirty during use of the cleaning device, and often needs to be cleaned or even replaced, so the disassembling roller brush assembly is arranged, and the transmission motor does not need to be disassembled, so that the roller brush assembly can be cleaned or replaced at any time.

[0126] In a preferred example, the rolling brush assembly is provided with a rolling brush detection structure, which can detect whether the flexible cleaning layer on the rolling brush assembly has water. In a further preferred example, the flexible cleaning layer is rubber cotton, and the rolling brush detection structure is in contact with the rubber cotton. As is known, rubber cotton will become hard after long-term dry storage, and will only become soft after being added with water. Therefore, the rolling brush detection structure is provided to detect whether the rubber cotton rolling brush has water before the cleaning device starts cleaning. If there is no water, the rubber cotton rolling brush is pre-watered before starting to clean the ground or surface, so as to avoid the hard rubber cotton rolling brush being unable to clean. In one example, the rolling brush detection structure is a conductive contact. The device body is provided with at least one group of conductive contacts. Each group of conductive contacts includes two spaced-apart conductive contact heads. The two conductive contacts are respectively connected to the power module through wires. Whether the two conductive contacts are conductive can be used to detect whether the rubber cotton has water. The two conductive contact heads of each group of conductive contacts are in contact with the rubber cotton. When the rubber cotton rolling brush has no water, the two conductive contact heads cannot form a closed circuit, and the detected resistance is very large. When the rubber cotton rolling brush has water, the two conductive contact heads form a closed circuit, and the detected resistance becomes small.

[0127] Working principle: The control module sets an upper limit value. When the cleaning device is in use, the control module controls the rolling brush detection structure to detect the resistance value. If the resistance value is greater than the upper limit value, it means that the rubber cotton rolling brush has no water, and the rubber cotton cannot clean the ground at this time. The control module controls the clean water tank to supply water to the rubber cotton. When the rolling brush detection structure detects that the resistance value is less than the lower limit value, it means that the rubber cotton has been watered or the rubber cotton rolling brush has water, i.e. the rubber cotton is soft and can be used to clean the ground. At this time, the control module controls the clean water tank to stop supplying water to the rubber cotton rolling brush or the cleaning device starts the cleaning mode.

[0128] Of course, the rolling brush detection structure can also be a sensor. The sensor is in contact with the rubber cotton rolling brush of the rolling brush assembly. The sensor can detect whether the rubber cotton rolling brush has water or not. The sensor includes a water immersion sensor or other detection sensors, etc.

[0129] The rolling brush detection structure provided in the present application can detect whether the rolling brush assembly has water, prevent the hard flexible cleaning layer, especially the hard rubber cotton, from being unable to clean the ground, and make the cleaning device more intelligent. After the cleaning device is started, the rolling brush detection structure first detects whether the rolling brush has water. If there is water, it means that the rubber cotton is in a soft state and can directly clean the ground. If the rubber cotton has no water, it means that the rubber cotton rolling brush is in a dry state. The control module controls the water supply motor to supply water to the rubber cotton. If the rolling brush detection structure detects that the rubber cotton has water, the water supply motor stops supplying water to the rubber cotton, and the cleaning device starts the cleaning operation.

[0130] It should be noted that all the technical features of the above cleaning device can be freely combined without conflict, and the free combination or simple modification, change and modification thereof are within the protection scope of the present patent.
