[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] It should be noted that if the embodiments of this utility model involve directional indication, the directional indication is only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0030] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0031] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] refer to Figure 1 and 2 The figure discloses a wet cleaning device 100, which includes a main unit 1 and a cleaning head 2 movably connected to the main unit 1. The main unit 1 generally defines a receiving space, within which components such as a wastewater tank, a suction motor, and a clean water tank can be placed. The cleaning head 2 includes an upper housing 28 and a lower housing 29. The upper housing 28 and lower housing 29 define an installation space. A motor, etc., can be installed within the installation space. Since the wet cleaning device 100 is a device well known to those skilled in the art, its working principle will not be described in detail here. (Reference) Figure 1-9The structure of the cleaning head 2 is described in detail below. The cleaning head 2 defines a suction chamber, within which a roller brush 22 is installed. A first scraper 23 is positioned at the edge of the suction chamber, and the first scraper 23 is press-fitted against the surface to be cleaned to scrape away at least part of the dirt. The cleaning head 2 also includes a second scraper 24 positioned behind the first scraper 23. The second scraper 24 is harder than the first scraper 23. The first scraper 23 can be made of a relatively soft rubber material, which can deform upon contact with a hard surface to better conform to the surface and scrape away dirt and water stains. The second scraper 24 can also be made of rubber, but it is harder and does not deform significantly upon contact with a hard surface, thus providing scraping force against stubborn stains. Due to the higher hardness of the second scraper 24, prolonged use may damage the surface to be cleaned, as the second scraper 24 can move between a first position and a second position. In the first position (refer to...) Figure 5 The second scraper 24 contacts the surface to be cleaned to scrape away at least part of the dirt on the surface as the cleaning head 2 moves. In the second position (refer to...) Figure 3 The second scraper 24 is moved away from the surface to be cleaned. A driver 25 is used to move the second scraper 24 between a first position and a second position. When there is stubborn dirt on the floor that the roller brush 22 cannot remove, the second scraper 24 can be moved to the first position. In this position, because the hardness of the second scraper 24 is much greater than that of the first scraper 23, the second scraper 24 scrapes the surface to be cleaned to remove stubborn stains.

[0033] Drive 25 can be a manual drive 25 or an automatic drive 25. (See reference) Figure 5-9 When the driver 25 is a manual driver 25, the driver 25 includes a driver 26 and a transmission member 27 that drives the driver 26 and the second scraper 24. The cleaning head 2 includes an upper housing 28 and a lower housing 29. The driver 26 is disposed on the cleaning head 2 and protrudes from the upper housing 28 so that it can be operated by the user. As shown in the figure, when the user pulls the driver 26 backward, the second scraper 24 can be retracted. When the user pushes the driver 26 forward, the driver 26 can drive the second scraper 24 to move downward relative to the lower housing 29 through the transmission member 27 to contact the surface to be cleaned.

[0034] In another embodiment, the drive member 26 is disposed on the handle 11 of the main unit 1, and the transmission member 27 is connected to the drive member 26 and the second scraper 24. The user controls the movement of the second scraper 24 between a first position and a second position by means of the drive member 26 located on the handle 11.

[0035] When the driver 25 is an automatic driver 25, the driver 25 includes a drive motor and a controller for controlling the drive motor. The controller is configured to drive the drive motor according to a signal to control the movement of the second scraper 24 between a first position and a second position. The handle 11 may be provided with a control button for issuing a control signal through the control button, and the controller controls the movement of the second scraper 24 between the first position and the second position according to the signal issued by the control button.

[0036] refer to Figure 3 and 5 The cleaning head 2 includes an upper housing 28 and a lower housing 29. When the second scraper 24 is in the second position, it moves into the receiving cavity defined by the lower housing 29. That is, when the second scraper 24 is in the second position, the bottom of the second scraper 24 can be completely retracted into the lower housing 29. Retracting the second scraper 24 completely into the receiving cavity can prevent damage to the ground due to unevenness.

[0037] refer to Figure 3 , 5 6. The cleaning head 2 also includes a first roller assembly 30 disposed behind the first scraper 23 and a second roller assembly 31 disposed at the rear end of the cleaning head 2. The first roller assembly 30 and the second roller assembly 31 jointly support the cleaning head 2. The second scraper 24 is disposed between the first roller assembly 30 and the second roller assembly 31. When the second scraper 24 is in the first position, the lowermost end of the second scraper 24 is lower than the plane defined by the first roller assembly 30 and the second roller assembly 31.

[0038] To improve the cleaning effectiveness of the second scraper 24, the first roller assembly 30 separates from the hard surface after the second scraper 24 contacts it. At this time, the first roller assembly 30 does not contact the ground, and the second scraper 24 and the second roller assembly 31 jointly support the cleaning head 2. The second scraper 24 experiences greater force, resulting in a better cleaning effect.

[0039] Along the length of the roller brush 22, the length of the second scraper 24 is less than half the length of the roller brush 22. If the second scraper 24 is too long, the cleaning effect may be reduced, and it may not be able to perform targeted cleaning.

[0040] This application also provides a cleaning system, which includes the wet cleaning device 100 in any of the above embodiments and a base station for docking the wet cleaning device 100.

[0041] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
