[0026] To explain in detail the technical content, structural features, achieved objectives and effects of the utility model, the technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0027] Please refer to Figure 1 This application provides a surface cleaning device 100. The cleaning device 100 includes a vertical body 1 and a cleaning brush device 2. The cleaning brush device 2 is rotatably connected to the lower part of the vertical body 1. The vertical body 1 is equipped with functional components such as a supply tank 11, a waste liquid tank 12 for receiving waste liquid, and a suction motor (not shown in the figure). When the surface cleaning device 100 is working, the supply tank 11 provides cleaning fluid for cleaning, and the cleaning brush device 2, under the action of the suction motor, continuously sucks the dirt and waste liquid on the surface to be cleaned into the vertical body 1 and stores it in the waste liquid tank 12.

[0028] See Figure 2 , Figure 3 The cleaning brush device 2 is movable along the surface to be cleaned and includes a base 21, a roller brush 23 supported at the front of the base 21 and rotatable about its own axis, and a roller brush cover assembly 24 covering the upper side of the roller brush 23 and connected to the base 21. The roller brush cover assembly 24 is detachably mounted at the front of the base 21. During operation, the roller brush 23 contacts the target surface and continuously rubs the target surface by rotating continuously, thereby cleaning the target surface.

[0029] The base 21 is also provided with a suction channel (not shown in the figure) that connects to the waste tank 12, a roller brush motor that drives the roller brush 23 to rotate around its own axis, and a fluid distributor for distributing cleaning liquid from the supply tank 11 onto the roller brush 23.

[0030] See Figure 4 and Figure 5 The roller brush cover assembly 24 includes an upper housing 241, a lower cover plate 242 fixedly installed on the lower part of the upper housing 241, and a pair of positioning components 243 installed on the lower cover plate 242. A limiting block 2421 is also provided at the rear of the lower cover plate 242. The pair of positioning components 243 are distributed on the left and right sides, and each positioning component 243 includes a fixing seat 2431, a protrusion 2432, and a spring 2433. The protrusion 2432 is elastically supported on the fixing seat 2431 by the spring 2433.

[0031] See Figure 6 As shown, the protrusion 2432 has a hollow structure inside, the spring 2433 is housed inside the protrusion 2432, and the protrusion 2432 is connected to one end of the spring 2433.

[0032] Combination Figure 3 The base 21 has a pair of left-right locating grooves 211. Each locating groove 211 is configured to allow a corresponding protrusion 2432 to be inserted in a first direction (in this example, the first direction is from right to left) and to be withdrawn in a second direction opposite to the first direction (i.e., from left to right). When each protrusion 2432 is inserted into the corresponding locating groove 211, the brush cover assembly 24 is limited in the vertical direction and cannot move upward or downward relative to the base 21. A locking mechanism 25 is also provided at the front of the base 21.

[0033] See Figure 7 , Figure 8 and Figure 9 As shown, the locking mechanism 25 includes a latch 251 movable between a locked position and an unlocked position in a front-back direction, a spring 252 with one end abutting against the latch 251, a button 253 movable in a vertical direction, and a spring 254 disposed between the button 253 and the latch 251. The latch 251 has a ramp 2511 adapted for the button 253 to slide along it; when the button 253 is pressed downwards, the button 253 slides along the ramp 2511 and pushes the latch 251 backwards, thus moving the latch 251 from the locked position toward the unlocked position. The spring 254 allows the button 253 to return to its original position upwards after the pressing force applied to it is removed. The spring 252 is used to drive the latch 251 toward the locked position or hold it in the locked position after the pressing force applied to it is removed. In this example, the button 253 is disposed on the top of the base 21.

[0034] The latch 251 is also provided with a guide profile 2512. When the roller brush cover assembly 24 is mounted on the base 21 in the first direction, the limiting block 2421 will abut against the guide profile 2512, thereby pushing the latch 251 to move toward the unlock position so that the latch 251 can avoid the limiting block 2421.

[0035] like Figure 10 As shown, the latch 251 can engage with the stop block 2421 on the brush cover assembly 24. When the latch 251 is in the locked position, it holds the brush cover assembly 24 on the seat 21; when the latch 251 is in the unlocked position, it releases the brush cover assembly 24, allowing it to move in a second direction. In this example, when the latch 251 is in the locked position, the latch 251 and the stop block 2421 are arranged side-by-side in the first direction and are in contact with each other to prevent the brush cover assembly 24 from moving in the second direction.

[0036] Continue as Figure 6 As shown, spring 2433 is compressed when the brush cover assembly 24 is held on the seat 21. When the latch 251 is switched to the unlocked position to release the brush cover assembly 24 from the seat 21, spring 2433 will provide a force for the brush cover assembly 24 to move in the second direction.

[0037] In this embodiment, the spring 2433 can drive the brush cover assembly 24 to spring outward when the brush cover assembly 24 is released, thereby facilitating the user to remove the brush cover 24 from the base 21.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope. The scope of protection of this utility model is defined by the appended claims, specification, and their equivalents.
