Note that the arrows in fig. 5 represent the direction of the urging force.

As for the housing structure of the cleaning device, when the rolling brush cover 200 is assembled to the base 100, the second lock catch 320 is slid in a direction close to the base 100 until the second lock catch 320 is locked with the first lock catch 310, so as to assemble the rolling brush 600; when the roller brush 600 needs to be detached from the base 100, an external force is applied to the driving member 330, and the driving member 330 is driven by the external force to rotate and drives the second latch 320 to slide in a direction away from the base 100 in the rotating process until the second latch 320 and the first latch 310 are unlocked, so that the rolling brush cover 200 and the base 100 are unlocked. And because the direction of the external force is the same as the direction that the rolling brush cover 200 breaks away from the base 100, the external force can drive the rolling brush cover 200 to rotate towards the direction far away from the base 100 in the process of driving the driving part 330 to rotate, so that the rolling brush cover 200 breaks away from the base 100, and the process of breaking away from the rolling brush 600 and the process of unlocking can be synchronously performed, so that the design of ergonomics is met, the operation is simple and rapid, time and labor are saved, the operation of a user is facilitated, and the user experience is improved.

In some embodiments of the present invention, as shown in fig. 4 to 7, the housing structure further comprises: and an elastic member 340 disposed between the secondary latch 320 and the roller brush cover 200, the elastic member 340 being used to provide a force for sliding the secondary latch 320 in a direction approaching the base 100. As an example, the elastic member 340 is disposed between an end of the second locker 320 remote from the base 100 and the roll brush cover 200. When the second latch 320 is driven by the driving member 330 to slide in a direction away from the base 100, the elastic member 340 is in a compressed state. After the rolling brush cover 200 is detached from the base 100, the driving member 330 stops driving the second latch 320 to slide in the direction away from the base 100 without being affected by external force, and the compressed elastic member 340 resets to push the second latch 320 to slide in the direction close to the base 100, so as to facilitate the rolling brush cover 200 to be assembled on the base 100 again.

For example, the guide slope 320a may be disposed at the bottom of the secondary locker 320, and the distance between the guide slope 320a and the base 100 is gradually increased in the top-down direction as shown in fig. 4. As another example, the guide slope 320a may be disposed on the top of the secondary locker 320, and the distance between the guide slope 320a and the base 100 is gradually decreased in the top-down direction as shown in fig. 3.

In some embodiments of the present invention, as shown in fig. 4 and 9, the first lock catch 310 has a groove-shaped structure; the secondary latch 320 includes: the locking part 322 is used for being clamped in the first lock catch 310, and the first abutting part 323 is used for abutting against the driving part 330 in the rotating process of the driving part 330. During the rotation of the driving member 330, the driving member abuts against the first abutting portion 323 of the second latch 320, so as to push the second latch 320 to slide in a direction away from the base 100 until the locking portion 322 is disengaged from the first latch 310.

As an example, the locking part 322 may be locked in the first locker 310 through a guide passage 350a of the guide 350, the guide slope 320a is provided at an end of the locking part 322 close to the first locker 310, and the second mounting part 321 is provided at the locking part 322, a wall of the first abutting part 323 far from the second locker 320.

The snap assembly 400 may improve the mounting strength of the roll brush cover 200 on the base 100. As an example, the latch assembly 300 vertically restrains the brush cover 200, and the catch assembly 400 horizontally restrains the brush cover 200.

Further, as shown in fig. 2, a first sidewall of the roll brush cover 200 is connected with a first sidewall of the base 100 by a latch assembly 300; the number of the buckle assemblies 400 is two, the second sidewall of the rolling brush cover 200 is connected with the second sidewall of the base 100 through one of the buckle assemblies 400, the third sidewall of the rolling brush cover 200 is connected with the third sidewall of the base 100 through another one of the buckle assemblies 400, the second sidewall and the third sidewall of the base 100 are distributed on two sides of the first sidewall, and the second sidewall and the third sidewall of the rolling brush cover 200 are distributed on two sides of the first sidewall. The locking assembly 300 can form a three-point locking structure with the two locking assemblies 400, so that the roller brush cover 200 can be more firmly connected to the base 100.

Alternatively, as shown in fig. 10, the second and third locking assemblies 410 and 430 include: a catch 400a provided on the roller brush cover 200 and a catch 400b provided on the base 100, the catch 400a being caught in the corresponding catch 400 b. It can be understood that the extending direction of the catch 400a is the same as the direction of the external force.

The following describes the process of attaching and detaching the brush cover 200:

when the rolling brush cover 200 is installed, the fasteners 400a on the two sides of the bottom of the rolling brush cover 200 are simultaneously fastened to the fastening grooves 400b on the two sides of the bottom of the base 100, so as to lock the second fastener 320 and the second fastener 320. Then, the pulling end of the pulling portion 331 is pressed downward and the elastic member 340 is reset, so that the fastening portion 322 of the second latch 320 is fastened in the first latch 310, and the second latch 320 and the first latch 310 are locked, thereby mounting the roll brush cover 200.

When the rolling brush cover 200 is disassembled, a user can dial the dial end of the dial portion 331 outwards, and the dial end rotates in a direction away from the dial slot 100a under the action of external force to drive the second abutting portion 333 to rotate. The second abutting portion 333 pushes the first abutting portion 323 of the second latch 320 in the rotating process, so that the first abutting portion 323 moves in the direction away from the base 100, so that the clamping portion 322 of the second latch 320 is separated from the first latch 310, thereby releasing the locking between the second latch 320 and the first latch 310, and then separating the fasteners 400a on the two sides of the bottom of the roller brush cover 200 from the slots 400b on the two sides of the bottom of the base 100, thereby releasing the locking of the second latch assembly 410 and the third latch assembly 420, thereby realizing the detachment of the roller brush cover 200.

Another embodiment of the present invention provides a housing structure for a cleaning apparatus, as shown in fig. 6, which includes a base 100, a brush cover 200, and a latch assembly 300 for mounting the brush cover 200 on the base 100; an anti-collision buffer 230 is arranged on the outer wall of the front end of the rolling brush cover 200, and a sealing element 240 is arranged at the periphery of the inner wall of the rear end of the rolling brush cover 200; the locking assembly 300 includes a first locking latch 310 disposed on the base 100 and a second locking latch 320 slidably disposed on the rolling brush cover 200, wherein the second locking latch 320 can slide in a direction close to the base 100 until it is locked with the first locking latch 310 or in a direction away from the base 100 until it is unlocked with the first locking latch 310.
