The following description will be given by taking a cleaning base as an example for convenience of explanation.

Referring to fig. 1-2, a schematic structural diagram of a cleaning base 100 according to an embodiment of the present application is shown. The cleaning base 100 includes a base body 1, an upper cover 2 which is positioned at an upper side of the base body 1 and detachably connected with the base body 1, and a cleaning roller 3 rotatably installed at a front portion of the base body 1. The detachable connection mode of the seat body and the upper cover is not limited, and the seat body and the upper cover can be connected through a buckle structure, a turnbuckle structure and the like. The construction of the snap-fit and turnbuckle arrangements is well known to those skilled in the art.

Bottom cover 201 is constructed to have a structure having a cavity therein that accommodates wiper 202, elastic member 205, and cam 2031. It should be noted that, in alternative other embodiments, the top cover and the bottom cover may be connected by other connection methods such as a turnbuckle connection, and the specific connection method does not limit the scope of the application.

Referring to fig. 4, a liquid delivery pipe 2012 for cleaning liquid and a liquid spray nozzle 2011 in fluid communication with the liquid delivery pipe 2012 are mounted on the bottom cover 201, and the liquid spray nozzle 2011 is used for dispensing cleaning liquid to the cleaning roller 3. In terms of the rotation direction of the cleaning roller 3, a liquid blocking plate 2014 having an upper end fixedly connected to the bottom cover 201 and a lower end abutting against the cleaning roller 3 is provided downstream of the liquid spraying nozzle 2011, the liquid blocking plate 2014 serving to prevent the cleaning liquid from flowing out from a gap between the bottom cover 201 and the cleaning roller 3 and uniformly adhere the cleaning liquid to the surface of the cleaning roller 3, thereby improving the use efficiency of the cleaning liquid. Meanwhile, the liquid baffle 2014 is designed to be a flexible structure close to the cleaning roller 3 in length so as to adapt to cleaning rollers with different working conditions or different radiuses.

The powerful liquid removing device 203 is integrally formed and comprises a pedal 2032 and a cam 2031, and a force applying base 2013 for rotationally connecting the powerful liquid removing device 203 with the bottom cover 201 is arranged on the bottom cover 201. Wherein the foothold 2032 includes a front leaf 20321 and a rear leaf 20322.

The top cover 204 is provided with a buckle 2042 for connecting with the bottom cover 201 and an opening 2041 for exposing the top cover 202 by the pedal 2032 for manual operation by a user, wherein the maximum rotation angle of the pedal 2032 is defined by the top cover 204 and the bottom cover 201.

Referring to fig. 7, the wiper strip 202 is provided as a rigid member having the same length as the cleaning roller 3. In this example, the cam 2031 is located above the scraper 202, the upper end surface of the scraper 202 abuts against the outer contour surface of the cam 2031, and at the same time, the first end D1 of the scraper 202 abuts against the outer surface of the cleaning roller 3 and the second end D2 is rotatably connected to the bottom cover 201. The rotation axis of the cleaning roller 3 is parallel to the rotation axis of the second end D2. A wiper seat 2014 for connecting the wiper 202 to the bottom cover 201 is provided on the bottom cover 201, a first rotation stopping rib 20151 for preventing the wiper 202 from crossing the first position T1 and a rotation stopping rib 20152 for preventing the wiper 202 from crossing the second position T2 are provided on the wiper seat 2015, an elastic member 205 is provided between the wiper 202 and the upper cover 2, and the elastic member 205 is configured to generate a force for continuously abutting the wiper 202 against the cleaning roller 3 in a deformed state.

The seat body 1 is provided with a roller seat 101 positioned at the front end part of the seat body 1 for rotationally connecting the cleaning roller 3 with the seat body 1, a liquid collecting cavity 102 positioned at the rear side of the roller seat 101 and being open, and a suction channel 103 positioned at the rear side of the liquid collecting cavity 102 and in fluid communication with the liquid collecting cavity 102. When the upper cover 2 is connected with the base 1, the upper cover 2 and the roller base 101 together define a front cavity 104 with an opening at the lower part, and the front cavity 104 is in fluid communication with the liquid collecting cavity 102. Under the action of surface tension, the scraping bar 202 scrapes off the sewage and the attached impurities from the cleaning roller 3, enters the liquid collecting chamber 102 from the front chamber 104 along the scraping bar 202, and finally is concentrated inside the liquid collecting chamber 102. Under the action of the negative pressure of the external air suction, the liquid collection cavity 102 collects sewage and impurities, and the sewage and impurities are led to the outside through the suction channel 103.

Referring to fig. 5, fig. 5 illustrates the positional relationship of the various components of the cleaning base 100 when the wiper strip 202 is in the first position. After the user steps on the front leaf 20321 of the pedal 2032, under the transmission effect of the pedal 2032, the cam 2031 rotates to a first angle A1, and the cam 2031 abuts against the scraper 202 at the rear part of the upper end face of the scraper 202. At this time, the cleaning roller 3 provides a friction force for the scraper bar 202 to rotate in a direction opposite to the second position T2, the elastic member 205 provides a force for the scraper bar 202 to rotate toward the second position T2 so that the scraper bar 202 continuously abuts against the cleaning roller 3, and the first rotation stopping rib 20151 prevents the scraper bar 202 from crossing the first position T1. The wiper strip 202 is in the first position T1 by the combined action of the cam 2031, the first stop rib 20151, the resilient member 205, and the cleaning roller 3.

Fig. 6 illustrates the wiper strip 202 in the second position. After the user steps on the rear leaf 20322 of the pedal 2032, under the transmission action of the pedal 2032, the cam 2031 rotates to a second angle A2, and the cam 2031 abuts against the front part of the upper end surface of the scraper 202 and restricts the scraper 202 from rotating towards the first position T1. At this time, the cleaning roller 3 provides a frictional force for the scraper bar 202 to rotate toward the first position T1, the elastic member 205 provides a force for the scraper bar 202 to rotate in a direction opposite to the first position T1 so that the scraper bar 202 continuously abuts against the cleaning roller 3, and the second rotation stop rib 20152 prevents the scraper bar 202 from passing over the second position T2. The wiper strip 202 is in the second position by the cooperation of the cam 2031, the second stop rib 20152, the resilient member 205, and the cleaning roller 3.

As can be seen by comparing fig. 5 and 6, the second frictional force F2 generated between the scraper bar 202 and the cleaning roller 3 in the second position T2 is greater than the first frictional force F1 between the scraper bar 202 and the cleaning roller 3 in the first position. The first position is used for separating easily separable liquid and accessory impurities carried on the surface of the cleaning roller 3, and the second position is used for separating difficult-to-separate liquid and accessory impurities absorbed by the cleaning roller 3. In the normal cleaning process, a user can place the scraping strip 202 at a first position through the powerful liquid removing device 203, and when the cleaning efficiency is reduced due to the fact that the liquid content of the cleaning roller is increased, the user can place the scraping strip 202 at a second position through the powerful liquid removing device 203, so that liquid absorbed in the cleaning roller 3 is quickly removed, and the cleaning efficiency is improved.

Referring to fig. 8-9, an embodiment of the present application provides a cleaning base 200 with another structure, and the cleaning base 200 is different from the cleaning base 100 in that a powerful liquid removing device with another structure is configured. The powerful liquid removing device comprises a commutator 2101 positioned on the upper side of the scraping strip 202 and abutted against the scraping strip 202, a sliding block 2102 positioned on the upper side of the commutator 2101 and abutted against the commutator, and a switch housing 2103 positioned on the upper side of the sliding block 2102 and abutted against the switch housing. The switch housing 2103 exposes the top cover through the opening 2041, facilitating the user to operate the sliding block 2102. The slider 2102 is provided to be movable left and right, and the commutator 2101 is provided to be movable up and down.

Referring to fig. 10-12, the principle of operation of the powerful liquid removal device is illustrated. As shown in fig. 9, when the user moves the switch housing 2103 to the left to contact the top cover, the first inclined surface M1 contacts the second inclined surface M2, and the commutator 2101 is at the first height H1. At this time, the cleaning roller 3 provides a first friction force for the scraper bar 202 to rotate in the opposite direction to the second position T2, the elastic member provides a force for the scraper bar 202 to rotate to the second position T2 so that the scraper bar 202 continuously abuts against the outer surface of the cleaning roller 3, and the first rotation stopping rib prevents the scraper bar 202 from crossing the first position T1. Under the combined action of the resilient member, the first anti-rotation rib and the cleaning roller, the wiper strip 202 is in a first position and the support diverter 2101 is at a first height H1.

As shown in fig. 10, when the user moves the switch cover 2103 to the right to abut against the top cover, the first inclined plane M1 and the second inclined plane M2 are separated, the left-right displacement of the sliding block 2102 is converted into the up-down displacement of the commutator 2101, the commutator 2101 moves downward, the commutator moves to the second height H2, and the scraper 202 is pressed against the second position T2. At this time, the cleaning roller provides a friction force for the scraper 202 to rotate toward the first position T1, the elastic member provides a force for the scraper 202 to rotate toward the first position T1, and the second rotation stop rib prevents the scraper 202 from passing over the second position T2. The wiper strip 202 is in the second position T2 under the combined action of the commutator 2101, the second anti-rotation rib, the elastic member and the cleaning roller.

The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the foregoing embodiments, which have been described in the foregoing embodiments and description merely illustrates the principles of the invention, and various changes and modifications may be made therein without departing from the spirit and scope of the invention, the scope of which is defined in the appended claims, specification and their equivalents.
