[0049] Example 1

[0050] like Figure 1 - Figure 8 The utility model provides a cleaning device, comprising: a cover body 1, a cleaning structure 2, a moving body 5 and a limiting structure.

[0051] The cover body 1 includes a cap cover 101 and a cap brim 102 . A cap cavity 103 is provided in the cap cover 101 . The cap brim 102 is arranged around the cap cover 101 , and the cap brim 102 is spaced apart from the surface to be cleaned.

[0052] The cleaning structure 2 is connected and arranged on the lower side of the brim 102, and can be but is not limited to a brush and a mop, etc. Specifically, the cleaning structure 2 is distributed in a ring shape and is connected to the lower side of the brim 102, and can contact and clean the surface to be cleaned. Preferably, ribs or grooves are arranged on the lower side of the brim 102 to increase the tightness of the connection with the cleaning structure 2. The ribs or grooves can be arranged in a mesh shape, radial shape or arc shape.

[0053] The moving body 5 is arranged in the cap cavity 103 and is suitable for moving along the surface to be cleaned. In this embodiment, a power source is arranged inside the moving body 5. As a convertible implementation method, the moving body 5 may not have a built-in power source and can move by external force, such as hand pushing.

[0054] The limiting structure limits the connection between the cover body 1 and the traveling body 5, and is suitable for being separated from the limiting connection with both or one of the cover body 1 and the traveling body 5 under the action of external force, so that the cover body 1 and the traveling body 5 are detachable.

[0055] By setting a limiting structure, the cover body 1 and the moving body 5 are respectively limitedly connected, and the connection with at least one of the two can be detached under external force to achieve detachability. This setting makes the limiting effect of the limiting structure adjustable. When it is necessary to take the cover body 1 and the moving body 5 at the same time, the limiting effect of the limiting structure can be maintained to achieve the overall taking and placing of the cleaning device. When it is necessary to take the cover body 1 and the moving body 5 separately, the limiting effect of the limiting structure can be cancelled by applying external force, so that both the cover body 1 and the moving body 5 can be detached to achieve separate taking and placing.

[0056] The limiting structure includes a limiting member 6 and a trigger member 7. In this embodiment, the limiting member 6 is connected to both the cover body 1 and the traveling body 5, and the trigger member 7 drives the limiting member 6 to break away from the limiting connection with the traveling body 5 under the triggering of an external force. That is, the limiting member 6 is detachably connected to the traveling body 5 and maintains a limiting connection with the cover body 1.

[0057] Specifically, the trigger member 7 includes a touch cover 701 and an abutting portion 703 .

[0058] The touch cover 701 is movably connected to the cover body 1 and exposed outside the cover body 1, suitable for bearing external force. Preferably, the touch cover 701 is arranged on the top side of the cover body 1, and further, arranged on the central axis of the cover body 1. This is convenient for users to identify and apply force, and avoids accidental touch when taking and placing the cleaning device as a whole. The abutment portion 703 is arranged on the touch cover 701, and is used to abut against the limiter 6 and drive the limiter 6 to break away from the limit connection with the traveling body 5.

[0059] In this embodiment, the position-limiting member 6 includes two position-limiting blocks 601, and the position-limiting blocks 601 are connected to the traveling body 5 and the cover body 1. Specifically, the position-limiting blocks 601 are detachably connected to the traveling body 5 and maintain a position-limiting connection with the cover body 1. The number of the abutting portions 703 corresponds to that of the position-limiting member 6, and is also two. Each position-limiting block 601 is suitable for being disengaged from the position-limiting connection with the traveling body 5 under the drive of the corresponding abutting portion 703. As a convertible embodiment, the position-limiting member 6 includes one or more position-limiting blocks 601, and one or more abutting portions 703 are correspondingly provided.

[0060] In this embodiment, the two limit blocks 601 are evenly distributed around the central axis of the traveling body 5. Driven by the two abutting parts 703, the two limit blocks 601 gather toward the central axis to break away from the limit connection with the traveling body 5 or the cover body 1. The two limit blocks 601 are provided to balance the force and avoid stress concentration while keeping the cost low. The movement stroke driven by the abutting parts 703 is relatively uniform. As a convertible embodiment, the number of the limit blocks 601 can be one or more.

[0061] In this embodiment, the abutment portion 703 is provided with an inclined surface, and the position-limiting block 601 is disengaged from the position-limiting connection with the traveling body 5 under the drive of the inclined surface; as a convertible implementation, an inclined surface may also be provided on the position-limiting block 601. When the position-limiting block 601 is provided with an inclined surface, the inclined surface causes the position-limiting block 601 to be disengaged from the position-limiting connection with the traveling body 5 under the drive of the abutment portion 703. As another convertible implementation, both the abutment portion 703 and the position-limiting block 601 are provided with inclined surfaces, and they cooperate with each other. The setting of the inclined surface can adjust the direction of the driving force to achieve the effect of guiding movement.

[0062] The limiting member 6 includes not only the limiting block 601 but also an elastic member 603, which is connected to the limiting block 601 and is suitable for applying an elastic force to the limiting block 601 and driving the limiting block 601 to reset. The setting of the elastic member 603 can provide a driving force for resetting the limiting block 601. As a convertible embodiment, the elastic member 603 can also be omitted and replaced by a magnetic member or the like.

[0063] In this embodiment, the limiting structure is disposed on the cover body 1 and is detachably connected to the traveling body 5 by snap-fitting.

[0064] Specifically, the cover body 1 includes a first matching portion 104 and a limiting inner cavity 105 .

[0065] The first matching portion 104 is arranged on the central axis of the partially spherical cover body 1, with one end protruding toward the cap cavity 103, and the outer wall of the first matching portion 104 is provided with a first through hole 109 and a second through hole 110. The limiting inner cavity 105 is arranged in the first matching portion 104, and the limiting inner cavity 105 has a built-in limiting structure. The limiting block 601 passes through the limiting inner cavity 105 from the first through hole 109 and is detachably connected to the traveling body 5. The abutment portion 703 passes through the second through hole 110 and is engaged with the first matching portion 104 for limiting. Specifically, a barb portion is provided on the abutment portion 703, which can pass through the second through hole 110 and be limited by the second through hole 110.

[0066] The limiting inner cavity 105 provides a space for the limiting structure and the abutting portion 703 to be placed and moved, and the first matching portion 104 arranged on the central axis is convenient for matching with the output end 302 of the driving member 3 arranged in the traveling body 5. As a convertible embodiment, the first matching portion 104 can also be arranged at a non-central axis position of the cover body 1.

[0067] The traveling body 5 includes: a housing 501 and a second matching portion 502 .

[0068] Among them, the top side of the shell 501 is adjacent to the inner wall of the cap cavity 103 and is arranged at an interval; the second matching part 502 is groove-shaped, arranged on the shell 501, opening toward the first matching part 104, and has part of the first matching part 104 built in, and can also accommodate the entire first matching part 104, and a limiting inner protrusion 504 is provided on the inner wall of the opening of the second matching part 502, and the limiting inner protrusion 504 is connected to the limiting block 601 for limiting.

[0069] The limiting inner protrusion 504 can be connected to the limiting block 601 that passes through the limiting inner cavity 105 from the first through hole 109, so that the limiting block 601 can limit the moving body 5 and the cover body 1 at the same time, and when the limiting block 601 returns from the first through hole 109, it will be disengaged from the limit, thereby realizing the detachable connection of the limiting member 6 and the moving body 5, and the structure is simple and easy to implement.

[0070] The cleaning device further comprises an axial hole 503 and a shaft connecting portion.

[0071] The through-axis hole 503 is arranged on the second matching portion 502, and the central axis of the cover body 1 passes through the through-axis hole 503. The connecting shaft portion is cylindrically protruding and arranged on the first matching portion 104, and is also coaxial with the central axis of the cover body 1. The driving member 3 is specifically a motor, including a driving body 301 and an output end 302. The driving body 301 is arranged in the housing 501, and the output end 302 is the motor output shaft. The output end 302 passes through the through-axis hole 503 and is limitedly connected with the connecting shaft portion, which is suitable for driving the cover body 1 to rotate relative to the traveling body 5.

[0072] Preferably, the radial cross-section of the through-axis hole 503 and the radial cross-section of the output end 302 are non-circular, and the through-axis hole 503 and the output end 302 are suitable for limiting each other in the circumferential direction and being movably connected in the axial direction. The through-axis hole 503 and the output end 302 arranged in this way can ensure that the driving member 3 and the cover body 1 form a circumferential limit, and the driving member 3 can drive the cover body 1 to rotate in the circumferential direction. It can also realize plug-in installation and removal, and improve the efficiency of assembly and removal.

[0073] Example 2

[0074] like Fig. 9 - Fig.19 As shown, this embodiment is modified on the basis of the embodiment 1, and also provides a cleaning device, including: a cover body 1, a cleaning structure 2, a moving body 5 and a limiting structure.

[0075] In this embodiment, the limiting structure includes a limiting member 6 and a trigger member 7. The limiting member 6 is connected to both the cover body 1 and the traveling body 5, and the trigger member 7 drives the limiting member 6 to break away from the limiting connection with the cover body 1 under the triggering of an external force. That is, the limiting member 6 is detachably connected to the cover body 1 and maintains a limiting connection with the traveling body 5.

[0076] The trigger member 7 includes: a touch cover 701 and an abutting portion 703. The abutting portion 703 is disposed on the touch cover 701, and is used to abut against the limiting member 6 and drive the limiting member 6 to break away from the limiting connection with the cover body 1.

[0077] In this embodiment, the limiting member 6 includes at least one limiting block 601, which is connected to the moving body 5 and the cover body 1 in a limiting manner. The number of abutment portions 703 corresponds to the limiting member 6, and each limiting block 601 is suitable for being disengaged from the limiting connection with the cover body 1 under the drive of the corresponding abutment portion 703.

[0078] In this embodiment, a slope is provided on the abutment portion 703, and the limit block 601 is disengaged from the limit connection with the cover body 1 under the drive of the slope; as a convertible implementation method, a slope can also be provided on the limit block 601. When the limit block 601 is provided with a slope, the slope causes the limit block 601 to be disengaged from the limit connection with the cover body 1 under the drive of the abutment portion 703.

[0079] In this embodiment, the limiting structure is disposed on the traveling body 5 and is detachably engaged with the cover body 1 .

[0080] Specifically, the limiting structure further includes a third limiting sub-portion 607 and a second limiting sub-portion 606 .

[0081] Among them, the third limiting sub-portion 607 is tray-shaped and is preferably arranged on the central axis of the moving body 5.

[0082] The second limiting sub-section 606 is buckled on the third limiting sub-section 607, and is sandwiched with the third limiting sub-section 607 to form an accommodation space, and the accommodation space accommodates the limiting block 601. One end of the limiting block 601 passes through the lateral opening of the accommodation space and is engaged with the cover body 1. The trigger member 7 passes through the opening on the second limiting sub-section 606 and into the accommodation space, and is engaged with the limiting block 601. In this embodiment, the portion of the limiting block 601 disposed in the accommodation space is stepped, and is engaged with the trigger member 7, and is limited to the lateral opening, so that the limiting block 601 can be prevented from slipping out of the accommodation space.

[0083] The cover body 1 includes a first matching portion 104. The first matching portion 104 is a protruding structure of the cover body 1 toward the traveling body 5, and is arranged on the central axis of the cover body 1, specifically, the first matching portion 104 is coaxially arranged with the central axis of the cover body 1, and the first matching portion 104 includes a second ring portion 107, and the second ring portion 107 protrudes toward the cap cavity 103, and a limiting structure is arranged inside the second ring portion 107, and an arc hole 108 is arranged along the circumference of the second ring portion 107, and the arc hole 108 is suitable for engaging with the limiting block 601 for limiting.

[0084] A first matching portion 104 including a second ring portion 107 is provided, and the second ring portion 107 is circumferentially provided with an arc hole 108 which is engaged and limited with the limiting block 601. The first matching portion 104 provided in this way can be covered on the outer sides of the third limiting section 607 and the second limiting section 606, so that the limiting block 601 that can be telescopically moved can be connected with the first matching portion 104, the third limiting section 607 and the second limiting section, thereby enabling the limiting member 6 to be limited with the cover body 1 and the moving body 5.

[0085] In addition, the first matching portion 104 also includes a first ring portion 106, which is arranged on the inner side of the second ring portion 107, and is surrounded by the outer side of the trigger member 7, and is protruded toward the cap cavity 103. In addition, the protrusion degree of the first ring portion 106 is smaller than that of the second ring portion 107. A through hole exposing the trigger member 7 is provided on the inner side of the first ring portion 106, and the first ring portion 106 is suitable for guiding the trigger member 7 along its own protruding direction; preferably, the first ring portion 106 is provided with a guide hole, and the trigger member 7 is provided with a matching guide column.

[0086] The limiting structure further includes a first limiting sub-portion 605 , which is disposed between the second limiting sub-portion 606 and the first ring portion 106 and is limitingly connected to the first ring portion 106 . The first limiting sub-portion 605 is provided with a through hole for the trigger member 7 to pass through.

[0087] The setting of the first ring portion 106 can guide the movement of the trigger member 7 and avoid the movement deviation of the trigger member 7. At the same time, the first ring portion 106 and the first limiting structure are detachably limited and connected. In this way, on the basis of achieving the installation positioning of the first ring portion 106, it avoids affecting the detachable connection relationship between the limiting structure and the cover body 1, thereby ensuring the detachability of the cover body 1 and the moving body 5.

[0088] The traveling body 5 includes: a housing 501 and a second matching portion 502 .
