The present disclosure provides a cleaning apparatus including a machine body, a cleaning device, and a locking device, the machine body and the cleaning device being configured to be detachably connected and lockable together by the locking device. The cleaning equipment can be handheld equipment such as a dust collector and a hand-push type floor washing machine, and can also be self-moving cleaning robots such as a sweeping robot, a driving type floor washing machine and a floor washing robot. The cleaning device can be rag, brush disc, rolling brush, etc. and is used for cleaning the working surfaces of ground, wall, glass, etc. When the cleaning device needs to be replaced or cleaned, the cleaning device can be detached from the machine body.

The locking device comprises a first buckle component and a second buckle component which can lock the machine body and the cleaning device together when being matched. One of the first buckle component and the second buckle component is arranged on the machine body, and the other one is arranged on the cleaning device. Convenient disassembly and assembly between the machine body and the cleaning device can be realized through the locking device.

The second buckle assembly includes a fixed buckle and a movable buckle configured to be movable in a first direction to a first position or a second position. The movable buckle has a certain distance with the first buckle when moving to the first position, and is attached to the fixed buckle when moving to the second position.

When the first buckle assembly is located between the movable buckle and the fixed buckle, the fixed buckle and the first buckle assembly can be clamped together through the locking surface, so that the first buckle assembly is prevented from crossing the fixed buckle, and the cleaning device can be prevented from being separated from the machine body along the first direction.

In an embodiment of the disclosure, the first direction is an insertion direction or an installation direction of the cleaning device and the machine body, for example, the cleaning device is moved toward the machine body or away from the machine body along the first direction. The first buckle assembly and the second buckle assembly can be displaced in the second direction through extrusion deformation or self movement, so that the first buckle assembly can pass over the second buckle assembly. The second direction is different from the first direction, and the second direction and the first direction may be perpendicular to each other, or may be at other angles, as long as the directions are not the same.

In an embodiment of the disclosure, at least one of the first buckle assembly and the second buckle assembly can elastically deform along the second direction, so that the first buckle assembly can get over the fixed buckle and the movable buckle of the second buckle assembly after being extruded and elastically deformed along the second direction in the process of moving along the first direction, and the cleaning device and the machine body can be disassembled and assembled.

The locking surface and the guide surface of the present disclosure are defined from whether relative displacement in the second direction between the first snap assembly and the second snap assembly is facilitated or prevented, and the locking surface of the present disclosure refers to that relative displacement in the second direction between the first snap assembly and the second snap assembly is not facilitated or prevented when the first snap assembly and the second snap assembly are matched together through the locking surface. The guide surface is used for facilitating relative displacement between the first buckle assembly and the second buckle assembly in the second direction when the first buckle assembly and the second buckle assembly are matched together through the guide surface, so that the first buckle assembly passes over the second buckle assembly.

The technical solution of the cleaning device in the present disclosure will be described in detail with reference to specific structures.

Example one

Fig. 1 and 2 show schematic diagrams of a cleaning apparatus in which a body 1 and a cleaning device 2 are locked together, a first direction is a plugging direction of the cleaning device 2 and the body 1, and the first direction is a vertical direction with reference to the view directions of fig. 1 and 2, and the cleaning device 2 is disposed at a bottom position of the body 1. First buckle subassembly 3 sets up on organism 1, and second buckle subassembly 4 sets up on cleaning device 2, and second buckle subassembly 4 includes activity buckle 42 and fixed buckle 41, and activity buckle 42, fixed buckle 41 set up on cleaning device 2 along the first direction, and on cleaning device 2 and organism 1's grafting direction, activity buckle 42 sets up the position of keeping away from organism 1 on cleaning device 2 for fixed buckle 41, and fixed buckle 41 sets up the top at activity buckle 42 promptly. When the body 1 and the cleaning device 2 are locked, the movable buckle 42 is located at a first position far away from the fixed buckle 41, the first buckle assembly 3 is located at a position between the movable buckle 42 and the fixed buckle 41, and the first buckle assembly 3, the fixed buckle 41 and the movable buckle 42 interfere with each other in a first direction. At this time, the first engaging member 3 forms a locking surface 5 when being attached to the upper fixing engaging member 41, and is locked by the locking surface 5, so that the cleaning device 2 cannot move downward and be detached from the machine body 1.

The locking surface 5 mainly functions to lock the fixing buckle 41 and the first buckle assembly 3 together, when the cleaning device 2 leaves the machine body 1 along the first direction, the first buckle assembly 3 and the fixing buckle 41 are mutually blocked by the locking surface 5 and cannot be mutually staggered in the second direction, so that the machine body 1 and the cleaning device 2 are locked together, and the cleaning device 2 is prevented from being separated from the machine body 1. The locking surface 5 may be a plane parallel to the second direction, or an inclined plane capable of hooking the first buckle assembly 3 and the fixed buckle 41, and when the first buckle assembly 3 and the fixed buckle 41 are pressed by the locking surface 5, the acting force away from each other in the second direction is not generated.

In one embodiment of the present disclosure, as shown in fig. 2, the locking surface 5 includes a plane disposed on one side of the fixed catch 41 adjacent to the movable catch 42 and a plane disposed at a corresponding position of the first catch assembly 3, and both planes of the locking surface 5 are parallel to the second direction, so that the first catch assembly 3 and the fixed catch 41 cannot be displaced from each other in the second direction when being pressed by the locking surface 5.

The movable catch 42 is movable on the cleaning device 2 in a first direction between a first position and a second position. The movable buckle 42 can be kept at the first position by an elastic device or self gravity, and can move from the first position to the second position when being subjected to the external force action towards the fixed buckle 41, and the external force action can return to the first position under the action of the elastic device or the self gravity after being removed.

As shown in fig. 3 and 4, in the locked position, when the cleaning device 2 moves in the first direction to approach the machine body 1, the first catch assembly 3 is configured to move to the pre-unlocked position (shown in fig. 4) beyond the movable catch 42. When the first buckle component 3 presses the movable buckle 42, the two can move relatively along the second direction, so that the first buckle component 3 passes over the movable buckle 42.

In one embodiment of the present disclosure, as shown in fig. 3, in the locking position, the fixed catch 41 is located above the first catch assembly 3, and the movable catch 42 is located below the first catch assembly 3. The movable catch 42 has a third guide surface 8 between a side adjacent to the fixed catch 41 and a position corresponding to the first catch assembly 3. The third guide surface 8 is provided as an inclined surface and forms an acute angle with both the first direction and the second direction. The third guiding surface 8 comprises a slope arranged on the side of the movable catch 42 adjacent to the fixed catch 41 and a corresponding slope arranged on the first catch assembly 3, the slopes of the two slopes being in the same direction and cooperating with each other.

When the movable catch 42 is moved in the first direction relative to the first catch assembly 3, it can be moved from the locked position over the third guide surface 8 into the pre-unlocked position. When the movable catch 42 and the first catch assembly 3 are pressed against each other by the third guide surface 8, they are displaced and staggered relative to each other in the second direction, and the first catch assembly 3 can thus pass over the movable catch 42 and move to the pre-unlocking position as shown in fig. 4.

As shown in fig. 4, 5, 6, in the pre-unlocked position, when the cleaning device 2 is moved away from the machine body 1 in the first direction, the first catch assembly 3 is configured to: the movable catch 42 in the first position is pushed from the pre-unlocking position to move to the second position (shown in fig. 5) abutting against the fixed catch 41, and then is pressed and moved to the unlocking position (shown in fig. 6) across the movable catch 42 and the fixed catch 41, and the cleaning device 2 is detached from the machine body 1. It should be noted that the stroke of the movable catch 42 between the first position and the second position is smaller than or equal to the stroke of the cleaning device 2 in the first direction, so that the first catch assembly 3 can continue to move to the unlocking position after pushing the movable catch 42 to move from the first position to the second position.

In one embodiment of the present disclosure, as shown in fig. 5, in the pre-unlocking position, the first buckle assembly 3 is located below the movable buckle 42, and a first guide surface 6 is provided between a side of the movable buckle 42 away from the fixed buckle 41 and a position corresponding to the first buckle assembly 3. The first guide surface 6 is provided as an inclined surface and forms an acute angle with both the first direction and the second direction. The first guiding surface 6 comprises an inclined surface arranged on the side of the movable buckle 42 away from the fixed buckle 41 and an inclined surface correspondingly arranged on the first movable buckle 3, and the two inclined surfaces have the same inclined direction and can be matched with each other.

In the process of separating the cleaning device 2 from the machine body 1, as shown in fig. 4 and 5, the first buckle assembly 3 pushes the movable buckle 42 through the first guide surface 6, so that the movable buckle 42 moves from the first position to the second position; then, as shown in fig. 5 and 6, the movable catch 42 and the first catch component 3 are pressed against each other by the first guide surface 6, and the first catch component 3 and the fixed catch 41 are driven to be displaced from each other in the second direction, so that the first catch component 3 moves to the unlocking position over the movable catch 42 and the fixed catch 41.

In one embodiment of the present disclosure, in order to allow the first snap assembly 3 to pass over the movable snap 42 and the fixed snap 41, the first guiding surface 6 includes an inclined surface disposed on the movable snap 42, and the end of the movable snap 42 is flush with the end of the fixed snap 41 or exceeds the end of the fixed snap 41. This enables the first catch assembly 3 to smoothly pass over the movable catch 42 and the fixed catch 41 in sequence along the first guide surface 6 when the movable catch 42 is in the second position.

When the cleaning device 2 is disassembled, firstly, the body 1 and the cleaning device 2 which are locked together are close to each other along the first direction, the first buckle component 3 moves along the first direction from the locking position, is matched and extruded with the movable buckle 42 through the third guide surface 8, and moves to the pre-unlocking position under the guide effect of the third guide surface 8, and the first buckle component 3 moves in the second direction and passes over the movable buckle 42. Then, the cleaning device 2 is separated from the machine body 1 along the first direction, so that the first buckle assembly 3 pushes the movable buckle 42 to move from the first position to the second position, and the movable buckle 42 is pressed by the first guide surface 6, under the guiding action of the first guide surface 6, the first buckle assembly 3 passes through the movable buckle 42 and the fixed buckle 41, moves from the pre-unlocking position to the unlocking position, and the cleaning device 2 is separated from the machine body 1.

In some embodiments of the present disclosure, the movable catch 42 may be held in the first position by the force of its own weight, or the movable catch 42 may be held in the first position by the action of an elastic force.

In one embodiment, the movable catch 42 may be arranged on the cleaning device 2 by elastic means, held in the first position by the elastic action of the elastic means. In the process of moving from the locking position to the pre-unlocking position, the movable buckle 42 can overcome the elastic force of the elastic device to move from the first position to the second position under the pushing action of the first buckle component 3, and after the external force action is removed, the elastic device can drive the movable buckle 42 to reset to the first position. The elastic means includes, but is not limited to, a compression spring, an extension spring leaf, etc., which the present disclosure does not limit.

In some embodiments of the present disclosure, the movable catch 42 is provided on the machine body 1 or the cleaning device 2 through a guide structure extending in the first direction. The guiding structure may be a sliding block sliding groove structure, a sliding sleeve sliding rod structure, etc., and other conventional guiding structures capable of moving the movable buckle 42 between the first position and the second position are also within the scope of the present disclosure.

In another embodiment, as shown in fig. 1 and 2, the cleaning device 2 is installed at the bottom of the machine body 1, the movable buckle 42 is arranged below the fixed buckle 41, and the movable buckle 42 is kept at the first position by self gravity. During the movement from the locking position to the pre-unlocking position, the movable catch 42 is able to move from the first position to the second position against the force of gravity, pushed by the first catch assembly 3. After the external force is removed, the movable buckle 42 can fall back to the first position under the action of its own weight.

In the unlocked position, the first catch assembly 3 is located on the side of the fixed catch 41 remote from the movable catch 42. When the cleaning device 2 is installed, the cleaning device 2 is inserted into the machine body 1 along a first direction. The first catch assembly 3 presses against and passes over the fixing catch 41 and moves from the unlocked position to the locked position.

In one embodiment of the present disclosure, as shown in fig. 7, in the unlocked position, the first latch assembly 3 is located above the fixed latch 41, and the movable latch 42 is located at a first position away from the fixed latch 41. The side of the fixed catch 41 remote from the movable catch 42, which corresponds to the first catch assembly 3, has a second guide surface 7. When the fixed catch 41 moves upward relative to the first catch assembly 3 along the first direction, the second guide surface 7 presses the first catch assembly 3, and the first catch assembly 3 and the fixed catch 41 are displaced and staggered relative to each other in the second direction under the guiding action of the second guide surface 7, and then move to the locking position beyond the fixed catch 41. The second guide surface 7 may be an inclined surface forming an acute angle with both the first direction and the second direction. The second guiding surface 7 comprises an inclined surface arranged on the side of the fixed buckle 41 far away from the movable buckle 42 and an inclined surface correspondingly arranged on the first buckle component 3, and the two inclined surfaces have the same inclined direction and can be matched with each other.

The cleaning apparatus 2 is attached and detached as follows. When the cleaning device 2 is installed, the cleaning device 2 is inserted into the machine body 1 along the first direction, the first buckle assembly 3 moves to the locking position over the fixing buckle 41 under the action of the second guide surface 7, and the machine body 1 and the cleaning device 2 are locked together. When the cleaning device is disassembled, the cleaning device 2 is further inserted into the machine body 1 along the first direction, and the first buckle component 3 crosses the movable buckle 42 to move to a pre-unlocking position under the action of the third guide surface 8; the cleaning device 2 is then detached from the body 1 along the first direction, the first catch assembly 3 pushes the movable catch 42 from the first position to the second position and then moves over the movable catch 42 and the fixed catch 41 to the unlocked position under the action of the first guide surface 6.

In some embodiments of the present disclosure, the first buckle assembly 3 and the fixed buckle 41 and the movable buckle 42 respectively have relative displacement in the second direction through deformation and/or movement.

In a specific embodiment, the first buckle assembly 3 is configured as a first elastic sheet, one end of the first elastic sheet is fixedly connected with the machine body 1, and the end of the other end is configured as a hook portion capable of being matched with the second buckle assembly 4. A gap is reserved around the first elastic sheet for the first elastic sheet to move in the second direction. When the hook body part of the first elastic sheet is extruded with the movable buckle 42 through the first guide surface 6 or the third guide surface 8 and is extruded with the fixed buckle 41 through the second guide surface 7, the first elastic sheet is driven to generate elastic deformation in the second direction, so that the first buckle component 3 crosses the movable buckle 42 and the fixed buckle 41.

In one embodiment, the second latch assembly 4 comprises a second resilient piece, one end of the second resilient piece is fixedly connected to the cleaning device 2, and the fixed latch 41 and the movable latch 42 are disposed on the second resilient piece. When second buckle subassembly 4 extrudees through first spigot surface 6, second spigot surface 7 or third spigot surface 8 with first buckle subassembly 3, the drive second shell fragment takes place elastic deformation in the second direction to make first buckle subassembly 3 pass through the activity buckle 42, the fixed buckle 41 of second buckle subassembly 4.

In the embodiment of the present disclosure, both the first buckle assembly 3 and the second buckle assembly 4 may have a spring structure, and the displacement between the two in the second direction is realized through the deformation of the first buckle assembly and the second buckle assembly.

In addition to the above-described relative movement of the two catch assemblies in the second direction by means of elastic deformation, the above-described function can also be achieved by a total or partial movement of the first catch assembly 3 and/or the second catch assembly 4 itself. In one embodiment, as shown in fig. 8, the first latch assembly 3 is configured as a spring pin, one end of which is connected to the body 1 through a spring, and the other end of which is engaged with the second latch assembly 4 and can elastically move in the second direction. When the spring pin is matched with the second buckle assembly 4 through the first guide surface 6, the second guide surface 7 or the third guide surface 8, the spring pin is driven to extrude the spring to move in the second direction, so that the spring pin passes through the movable buckle 42 and the fixed buckle 41 of the second buckle assembly 4. When the external force is removed, the spring pin is reset under the acting force of the spring.

Based on the above disclosure, the first and second latch assemblies 3 and 4 can be displaced in the second direction by means of a spring, a slide pin, a torsion spring, a swing arm, and the like, which will not be described in detail herein. In the cleaning equipment disclosed by the invention, the cleaning device and the machine body can be assembled and disassembled in a reciprocating mode in the first direction, so that the structure is simple, and the operation is convenient and fast.
