Description

Technical Field

[0001] The utility model relates to the field of pivot connection structure design, in particular to a pivot control structure and a cleaning device having the same. Background Art

[0002] In daily production and life, pivot structures are widely used in various equipment. The two parts connected by them can rotate relative to each other, thereby realizing some specific functions.

[0003] The pivot connection structure in the related art can lock or unlock the pivot by adding a locking function. However, this structural design may cause many inconveniences during actual use. When it is necessary to perform some operations on the product to which the pivot structure belongs (such as cleaning, repair, storage, maintenance, etc.), it is often necessary to unlock the pivot connection structure. In some cases, the unlocking operation can be difficult, resulting in inconvenience in use.

[0004] For example, in cleaning equipment such as floor scrubbers and vacuum cleaners, the cleaning head is often connected to the body via a pivot structure. To facilitate placement, the body and the cleaning head can be fixed by locking the pivot structure, so that the body can be placed upright on the ground. However, when the main body of the cleaning equipment is placed on the base station to clean the cleaning head, since the cleaning head is fixed to the body, the cleaning head may not fit well with the relevant structures in the cleaning tank (for example, the cleaning head cannot adapt to the inclined bottom surface of the cleaning tank). In this case, the pivot structure needs to be manually unlocked, making the operation cumbersome. For another example, when storing or assembling certain products connected by a pivot structure, they need to be placed in a storage space or matching structure of a specific shape. At this time, the pivot structure also needs to be unlocked so that the components can rotate relative to each other for easy storage or assembly.

[0005] It can be seen that the pivoting structure in the related art needs to be manually unlocked according to usage requirements during use, which makes the operation cumbersome. Therefore, it has a technical problem of inflexible use. There is currently no effective solution to this technical problem. Utility Model Content

[0006] The main purpose of the utility model is to provide a pivot control structure and a cleaning device having the same, so as to solve the technical problem of inflexible use of the pivot structure in the related art.

[0007] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, a pivot control structure is provided, including a pivot part, which can be adapted to an accessory, and the pivot part includes: a first pivot part; a second pivot part, the second pivot part is pivotally connected to the first pivot part; a locking structure, the locking structure has a locked state and an unlocked state; when the locking structure is in the locked state, the locking structure restricts the relative rotation between the first pivot part and the second pivot part; when the locking structure is in the unlocked state, the locking structure does not restrict the relative rotation between the first pivot part and the second pivot part, or the restricting effect between the first pivot part and the second pivot part is less than that in the unlocked state; wherein, when the pivot part cooperates with the accessory, the accessory can trigger the locking structure to switch the locking structure from the locked state to the unlocked state.

[0008] Furthermore, when the pivoting portion is placed on the accessory, the pivoting portion cooperates with the accessory to cause the accessory to trigger the locking structure.

[0009] Furthermore, the second pivot portion pivots with the first pivot portion about a preset axis, and the locking structure includes: a rotating member, which is mounted on the first pivot portion; a locking member, which is movably arranged relative to the rotating member, and has a locking position and an unlocking position; when the locking member is in the locking position, the locking member can contact the rotating member to prevent the rotating member from rotating relative to the first pivot portion; when the locking member is in the unlocking position, the rotating member is rotatable relative to the first pivot portion about the preset axis; wherein, when the locking member is in the locking position, the rotating member can contact the second pivot portion to limit the relative rotation between the first pivot portion and the second pivot portion, and when the pivot portion cooperates with the accessory, the accessory can drive the locking member to move to the unlocking position.

[0010] Furthermore, the locking structure further comprises: a first elastic member, the first elastic member cooperates with the locking member, and when the pivoting portion is separated from the accessory, the locking member moves to the locking position under the action of the first elastic member.

[0011] Furthermore, the rotating member has a first protrusion; the locking member has a stop portion and an avoidance portion. When the locking member is in a locked position, the position of the first protrusion corresponds to the position of the stop portion; when the locking member is in an unlocked position, the position of the first protrusion corresponds to the position of the avoidance portion.

[0012] Furthermore, the first pivot portion has an initial position relative to the rotating member. When the first pivot portion is in the initial position relative to the rotating member and the locking member is in the locked position, the stop portion contacts the first protrusion, and the stop portion prevents the first pivot portion from rotating in a first direction relative to the rotating member; wherein the first pivot portion also has a first limiting portion, and the rotating member has a second limiting portion. When the first pivot portion is in the initial position relative to the rotating member, the first limiting portion contacts the second limiting portion to prevent the first pivot portion from rotating in a second direction relative to the rotating member, and the first direction and the second direction are opposite directions.

[0013] Furthermore, a groove is provided on the first pivot portion, which is a part of the annular groove, the first limiting portion is an end wall of the groove, and the second limiting portion is a protruding structure provided on the rotating member, and the protruding structure is movably provided in the groove along the extension direction of the groove; when the first pivot portion rotates relative to the rotating member in the first direction by a preset angle, the second limiting portion contacts the other end wall of the groove to prevent the first pivot portion from continuing to rotate relative to the rotating member in the first direction.

[0014] Furthermore, the locking structure includes a second elastic member. When the locking member is in the unlocked position and there is no external force between the first pivot part and the second pivot part driving the two to rotate relative to each other, the second elastic member drives the rotating member to rotate so that the first pivot part remains in an initial position relative to the rotating member.

[0015] Furthermore, the second elastic member is a spring arranged in the groove, one end of the spring abuts against one end wall of the groove, and the other end of the spring abuts against the rotating member.

[0016] Furthermore, a first stop block with a protruding arrangement is provided on the outer peripheral surface of the rotating member, and a second stop block is provided on the second pivot portion; when the locking member is in the locking position, the first stop block can contact the second stop block to limit the relative rotation between the first pivot portion and the second pivot portion.

[0017] Furthermore, the first stopper and / or the second stopper is a deformable or retractable structure. When the extrusion force between the first stopper and the second stopper reaches a threshold value, the first stopper and the second stopper disengage from contact under the action of deformation or retraction, so that the first pivot part and the second pivot part can rotate relative to each other.

[0018] According to another aspect of the present invention, a cleaning device is provided, which includes a body, a cleaning part, a base and the above-mentioned pivot control structure. The body and the cleaning part are pivotally connected by making the pivot part of the pivot control structure pivotable. The accessories of the pivot control structure are arranged on the base. The base includes a cleaning slot. When the body, the cleaning part and the pivot control structure are placed on the base, the locking structure of the pivot control structure is triggered by the accessories to an unlocked state, so that the cleaning part can rotate relative to the body in the cleaning slot.

[0019] Furthermore, when the main body, the cleaning portion and the pivot control structure are placed on the base, at least a portion of the bottom surface of the cleaning tank is inclined relative to the horizontal plane.

[0020] The pivot control structure applying the technical solution of the present invention includes a pivot part, which can be adapted to the accessory, and the pivot part includes: a first pivot part; a second pivot part, the second pivot part and the first pivot part are pivotally connected; a locking structure, the locking structure has a locked state and an unlocked state; when the locking structure is in the locked state, the locking structure restricts the relative rotation between the first pivot part and the second pivot part; when the locking structure is in the unlocked state, the locking structure does not restrict the relative rotation between the first pivot part and the second pivot part, or the restrictive effect between the first pivot part and the second pivot part is less than that in the unlocked state; wherein, when the pivot part cooperates with the accessory, the accessory can trigger the locking structure to switch the locking structure from the locked state to the unlocked state. With the pivot control structure of this structural design, the accessory can trigger the locking structure. When the pivot part cooperates with the accessory and the locking structure is in a locked state, the accessory can trigger the locking structure to an unlocked state, thereby enabling the first pivot part and the second pivot part to rotate more flexibly, thereby facilitating related operations on the two pivot parts or the structures connected thereto. For example, when the accessory triggers the locking structure to the unlocked state, the two-part structure connected to the first pivot part and the second pivot part can rotate relatively flexibly, thereby facilitating operations such as cleaning, repair, storage, and maintenance. This effectively improves the flexibility of use of the pivot control structure and solves the technical problem of inflexible use of the pivot structure in the related art.

[0040] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0041] Please refer to Figures 1 to 15 , an embodiment of the utility model provides a pivot control structure, which includes a pivot part, which can be adapted to the accessory 10, and the pivot part includes: a first pivot part 1; a second pivot part 2, which is pivotally connected to the first pivot part 1; a locking structure 3, which has a locked state and an unlocked state; when the locking structure 3 is in the locked state, the locking structure 3 restricts the relative rotation between the first pivot part 1 and the second pivot part 2; when the locking structure 3 is in the unlocked state, the locking structure 3 does not restrict the relative rotation between the first pivot part 1 and the second pivot part 2, or the restricting effect between the first pivot part 1 and the second pivot part 2 is less than that in the unlocked state; wherein, when the pivot part cooperates with the accessory 10, the accessory 10 can trigger the locking structure 3 to switch the locking structure 3 from the locked state to the unlocked state.

[0042] As described above, the locking structure 3 functions to restrict the relative rotation between the first pivot portion 1 and the second pivot portion 2. Restriction here can be understood as any form of obstruction to the mutual rotation between the two. For example, when the locking structure 3 is in the locked state, it locks the first pivot portion 1 and the second pivot portion 2 relative to each other, preventing them from rotating relative to each other. For another example, when the locking structure 3 is in the locked state, it restricts the range of relative rotation between the first pivot portion 1 and the second pivot portion 2. For another example, when the locking structure 3 is in the locked state, it applies a certain resistance to the pivoting between the first pivot portion 1 and the second pivot portion 2. It should be noted that the unlocked state is a state with a smaller restriction on pivoting than the locked state. Specifically, it can impose no restriction on the rotation between the first pivot portion 1 and the second pivot portion 2, allowing them to rotate freely. It can also restrict the range of relative rotation between the first pivot portion 1 and the second pivot portion 2, but the range of rotation is larger than that in the locked state. It can also apply a certain resistance to the pivoting between the first pivot portion 1 and the second pivot portion 2, but the resistance is smaller than that in the locked state, etc. According to different usage scenario requirements, similar locking structures can be flexibly selected.

[0043] With the pivot control structure of this structural design, the accessory 10 can trigger the locking structure 3. When the pivot part cooperates with the accessory 10 and the locking structure 3 is in a locked state, the accessory 10 can trigger the locking structure 3 to an unlocked state, thereby enabling the first pivot part 1 and the second pivot part 2 to rotate more flexibly, thereby facilitating related operations on the two pivot parts or the structures connected thereto. For example, when the accessory 10 triggers the locking structure 3 to an unlocked state, the two-part structure connected to the first pivot part 1 and the second pivot part 2 can rotate relatively flexibly, thereby facilitating operations such as cleaning, repair, storage, and maintenance. This effectively improves the flexibility of use of the pivot control structure and solves the technical problem of inflexible use of the pivot structure in the related art.

[0044] In a preferred embodiment, when the pivoting portion is placed on the accessory 10, the pivoting portion cooperates with the accessory 10, causing the accessory 10 to trigger the locking mechanism 3. The pivoting control structure of this embodiment only requires the pivoting portion to be placed toward the accessory 10 to unlock the locking mechanism 3, without requiring the operator to perform any special unlocking operations. This further simplifies the unlocking process of the pivoting control structure and makes the use of the pivoting structure more flexible and convenient.

[0045] As described above, when the pivoting portion of the accessory 10 is placed on the accessory 10, the accessory 10 can trigger the locking mechanism 3 to switch from the locked state to the unlocked state. This limitation only applies to the ability of the accessory 10 to trigger the locking mechanism 3 from the locked state to the unlocked state, and no other limitations apply. In other words, as long as the locking mechanism 3 is placed on the accessory 10 while in the locked state, it can be triggered to the unlocked state. There are no specific limitations on how the locking mechanism 3 can be assembled on the accessory 10 while in the unlocked state.

[0046] Specifically, the accessory 10 is a structure for placing or accommodating the pivoting part or the product to which it belongs. For example, the accessory 10 can be a base for supporting the pivoting part or the product to which it belongs. For another example, the accessory 10 can be a suspension structure for hanging the pivoting part or the product to which it belongs. For another example, the accessory 10 can be a packaging box for storing the pivoting part or the product to which it belongs, etc. In a specific embodiment, the pivoting part of the pivoting control structure is applied to cleaning equipment such as a floor scrubber, a vacuum cleaner, an electric mop, etc. The cleaning equipment has a body and a cleaning part for cleaning objects. The body and the cleaning part are pivotally connected by a pivoting part, and the accessory 10 is a base station for placing and supporting the cleaning equipment. Specifically, in addition to the supporting function, the base station can also have a series of additional functions, such as cleaning and charging the cleaning equipment.

[0047] In this embodiment, the second pivot part 2 pivots with the first pivot part 1 around a preset axis, and the locking structure 3 includes: a rotating member 31, which is installed on the first pivot part 1; a locking member 32, which is movably arranged relative to the rotating member 31, and the locking member 32 has a locking position and an unlocking position; when the locking member 32 is in the locking position, the locking member 32 can contact the rotating member 31 to prevent the rotating member 31 from rotating relative to the first pivot part 1; when the locking member 32 is in the unlocking position, the rotating member 31 is rotatable relative to the first pivot part 1 around the preset axis; wherein, when the locking member 32 is in the locking position, the rotating member 31 can contact the second pivot part 2 to limit the relative rotation between the first pivot part 1 and the second pivot part 2, and when the pivot part cooperates with the accessory 10, the accessory 10 can drive the locking member 32 to move to the unlocking position.

[0048] By designing a rotating member 31 rotatable relative to the first pivot portion 1 and a movable locking member 32, the locking member 32 switches between a locked position and an unlocked position to lock or unlock the rotating member 31 and the first pivot portion 1. When the locking member 32 is in the locked position, the rotating member 31 is locked to the first pivot portion 1, and the rotation between the first pivot portion 1 and the second pivot portion 2 is restricted by the interaction between the rotating member 31 and the second pivot portion 2. In other words, in this embodiment, the locking member 32 does not directly lock the first pivot portion 1 and the second pivot portion 2, but rather adds an intermediate rotating member 31. This allows the locking structure 3 to change the way the pivoting process is restricted by selecting the mode of engagement between the rotating member 31 and the second pivot portion 2, such as locking, limiting maximum torque, limiting rotation range, etc. Of course, in other optional embodiments, the locking member 32 can also be used to directly lock or unlock the first pivot portion 1 and the second pivot portion 2, which can be flexibly selected according to the specific functions and requirements of the applied product.

[0049] As mentioned above, when the locking member 32 is in the locked position, the locking member 32 can contact the rotating member 31 to limit the relative rotation of the rotating member 31 and the first pivot part 1. The rotation restricted here can be rotation in any direction in actual implementation, which can be limiting the mutual rotation of the two in both directions or any unidirectional mutual rotation.

[0050] Preferably, the locking structure 3 further includes: a first elastic member 33 , which cooperates with the locking member 32 , and when the pivoting portion is separated from the accessory 10 , the locking member 32 moves to the locking position under the action of the first elastic member 33 .

[0051] In this embodiment, a first elastic member 33 is also designed for the locking structure 3. The first elastic member 33 can apply a preload force to the locking member 32, thereby tending to maintain it in the locked position. Only when the pivoting portion is placed on the accessory 10 will the locking member 32 be triggered by the accessory 10 to the unlocked position. When the pivoting portion leaves the accessory 10 and the locking requirements are met, such as no interference with the locking action, the locking member 32 will return to the locked position under the action of the first elastic member 33, thereby tending to maintain the pivot control structure in the locked state and facilitating the use of the product to which it belongs. In actual implementation, the first elastic member 33 can be any elastic member capable of providing a preload force, such as a spring, a tension spring, an elastic band, etc.

[0052] In a specific embodiment, the rotating member 31 has a first protrusion 311; the locking member 32 has a stop portion 321 and an avoidance portion 322. When the locking member 32 is in the locked position, the position of the first protrusion 311 corresponds to the position of the stop portion 321; when the locking member 32 is in the unlocked position, the position of the first protrusion 311 corresponds to the position of the avoidance portion 322.

[0053] Here, when the locking member 32 is in the locked position, the first protrusion 311 corresponds to the position of the stop portion 321. That is, if the first protrusion 311 moves toward the stop portion 321, the stop portion 321 can stop the first protrusion 311. This does not mean that the stop portion 321 must contact the first protrusion 311 when the locking member 32 is in the locked position. Similarly, when the locking member 32 is in the unlocked position, the first protrusion 311 corresponds to the position of the avoidance portion 322. That is, if the first protrusion 311 moves toward the avoidance portion 322, the avoidance portion 322 can avoid the movement of the first protrusion 311, thereby ensuring that the first pivoting member 1 can rotate normally relative to the rotating member 31. This does not mean that the first protrusion 311 must be located within the avoidance portion 322 when the locking member 32 is in the unlocked position.

[0054] Specifically, the first pivot part 1 has an initial position relative to the rotating member 31. When the first pivot part 1 is in the initial position relative to the rotating member 31 and the locking member 32 is in the locked position, the stop part 321 contacts the first protrusion 311, and the stop part 321 prevents the first pivot part 1 from rotating in the first direction relative to the rotating member 31; wherein, the first pivot part 1 also has a first limiting part, and the rotating member 31 has a second limiting part 312. When the first pivot part 1 is in the initial position relative to the rotating member 31, the first limiting part contacts the second limiting part 312 to prevent the first pivot part 1 from rotating in the second direction relative to the rotating member 31, and the first direction and the second direction are opposite directions.

[0055] It should be noted that the naming of the initial position has no special restriction and is only used to distinguish it from other positions.

[0056] like Figure 13 As shown, in this embodiment, when the first pivoting portion 1 is in the initial position relative to the rotating member 31 and the locking member 32 is in the locked position, it can stop the relative rotation between the first pivoting portion 1 and the rotating member 31. Specifically, it prevents the first pivoting portion 1 from rotating in the first direction relative to the rotating member 31. On this basis, the first limiting portion on the first pivoting portion 1 and the second limiting portion 312 on the rotating member 31 can prevent the first pivoting portion 1 from rotating in the second direction relative to the rotating member 31. In this way, bidirectional rotation locking of the first pivoting portion 1 and the rotating member 31 is achieved, thereby improving the locking effect of the rotating portion.

[0057] In this embodiment, a groove 11 is provided on the first pivot portion 1, and the groove 11 is a part of the annular groove. The first limiting portion is an end wall of the groove 11, and the second limiting portion 312 is a protruding structure provided on the rotating member 31, and the protruding structure is movably provided in the groove 11 along the extension direction of the groove 11; when the first pivot portion 1 rotates by a preset angle in the first direction relative to the rotating member 31, the second limiting portion 312 contacts the other end wall of the groove 11 to prevent the first pivot portion 1 from continuing to rotate in the first direction relative to the rotating member 31.

[0058] like Figure 13 As shown, a groove 11 is provided on the first pivoting portion 1, which is a part of the annular groove, namely an arc-shaped groove. The second limiting portion 312 is a protruding structure provided on the rotating member 31, and the protruding structure is slidably provided in the arc-shaped groove. The above-mentioned first limiting portion is an end wall of the groove 11 in this embodiment. Therefore, when the second limiting portion 312 slides to the end of the groove 11 and contacts the end wall, the above-mentioned first limiting portion and the second limiting portion 312 are in contact.

[0059] Preferably, the locking structure 3 includes a second elastic member 34. When the locking member 32 is in the unlocked position and there is no external force between the first pivot part 1 and the second pivot part 2 driving the two to rotate relative to each other, the second elastic member 34 drives the rotating member 31 to rotate relative to the first pivot part 1, so that the first pivot part 1 remains in the initial position relative to the rotating member 31.

[0060] That is to say, in this embodiment, a second elastic member 34 is designed to apply elastic force between the first pivot part 1 and the rotating member 31. Under the action of the second elastic member 34, the first pivot part 1 tends to remain in the initial position relative to the rotating member 31. Therefore, when the locking member 32 is in the unlocked position and the first pivot part 1 rotates relative to the rotating member 31, the second elastic member 34 will deform and accumulate elastic potential energy. After the external force driving the first pivot part 1 to rotate relative to the rotating member 31 is removed, under the elastic action of the second elastic member 34, the first pivot part 1 will return to the initial position relative to the rotating member 31, thereby facilitating the locking operation of the locking member 32 and avoiding interference with the locking action of the locking member 32, which may lead to locking failure.

[0061] In actual implementation, the second elastic member 34 can be any elastic member that can provide a pre-tightening force, such as a spring, a tension spring, an elastic band, etc.

[0062] Specifically, if Figure 9As shown, in this embodiment, the second elastic member 34 is a spring disposed in the groove 11, with one end of the spring abutting against one end wall of the groove 11, and the other end of the spring abutting against the rotating member 31. In this way, the structure of the groove 11 is rationally utilized for the arrangement of the spring, so that the limiting function and the reset function are highly integrated, which is conducive to achieving the above-mentioned limiting and reset functions while making the relevant structural layout more compact.

[0063] In a specific embodiment, one end of the spring abuts against the first protrusion 311 on the rotating member 31, thereby fully utilizing the existing structure. A second protrusion 313 is also provided on the rotating member 31. The second protrusion 313 is spaced apart from the first protrusion 311, and the other end of the spring abuts against the second protrusion 313.

[0064] In actual implementation, the rotational cooperation structure between the first pivot portion 1 and the rotating member 31 can be varied, as long as the rotating member 31 is installed on the first pivot portion 1 and can ensure relative rotation between the two. For example, in a preferred embodiment, the first pivot portion 1 is provided with an annular groove, and the main structure of the rotating member 31 is a cylindrical structure, which is embedded in the annular groove, thereby achieving assembly between the two and ensuring mutual rotation. To prevent the rotating member 31 from escaping from the annular groove, the locking structure 3 in this embodiment also includes a limiter 35, which is installed on the first pivot portion 1 to prevent the rotating member 31 from escaping from the annular groove. Specifically, in this embodiment, the above-mentioned groove 11 is a groove segment provided on the annular groove, the width of which is greater than the width of the remaining groove segments of the annular groove, and the second limiter 312 is a protrusion provided on the inner wall and / or outer wall of the cylindrical structure. The first protrusion 311 and the second protrusion 313 are protrusions provided at the end of the cylindrical structure.

[0065] Specifically, a first stop block 314 is provided on the outer peripheral surface of the rotating member 31, and a second stop block 21 is provided on the second pivot part 2; when the locking member 32 is in the locked position, the first stop block 314 can contact the second stop block 21 to limit the relative rotation between the first pivot part 1 and the second pivot part 2.

[0066] As described above, the embodiments of the present invention, by adding an additional intermediate rotating member 31, can change the manner in which the locking structure 3 restricts the pivoting process by selecting the form of cooperation between the rotating member 31 and the second pivoting portion 2, such as locking, limiting the maximum torque, limiting the rotation range, etc. In a specific embodiment, the outer peripheral surface of the rotating member 31 is provided with a raised first stop 314, and the second pivoting portion 2 is provided with a second stop 21. When the locking member 32 is in the locked position, the first stop 314 can contact the second stop 21, thereby significantly reducing the relative rotation between the two. In specific implementation, according to specific usage requirements, the setting position of the first stop 314 and / or the second stop 21 can be flexibly adjusted, thereby adjusting the relative rotation range between the first pivoting portion 1 and the second pivoting portion 2 in the locked state or locking both so that they cannot rotate, thereby achieving flexible and effective restriction of the rotation process through a relatively simple structure.

[0067] Specifically, the first stop block 314 and / or the second stop block 21 are deformable or retractable structures. When the extrusion force between the first stop block 314 and the second stop block 21 reaches a threshold value, under the action of deformation or retraction, the first stop block 314 disengages from the second stop block 21, so that the first pivot part 1 and the second pivot part 2 can rotate relative to each other.

[0068] In this embodiment, by designing the first stopper 314 and / or the second stopper 21 as a deformable or retractable structure, when the applied force exceeds a threshold, the two stops will disengage due to deformation or retraction, thereby enabling relative rotation between the first pivot portion 1 and the second pivot portion 2. Depending on actual needs, this structure can be used to achieve different functions, such as locking and conveniently unlocking a product at a specific rotation angle, or protecting the pivot control structure by disengaging the two stops under the action of a limit force, allowing the first pivot portion 1 and the second pivot portion 2 to rotate relative to each other, thereby preventing damage due to excessive force when the pivot control structure is locked.

[0069] In addition, an embodiment of the present invention also provides a cleaning device, which includes a main body 100, a cleaning part 200, a base 300 and the above-mentioned pivot control structure. The main body 100 and the cleaning part 200 are pivotally connected by making the pivot part of the pivot control structure pivotable. The accessory 10 of the pivot control structure is arranged on the base 300. The base 300 includes a cleaning slot. When the main body 100, the cleaning part 200 and the pivot control structure are placed on the base 300, the locking structure 3 of the pivot control structure is triggered by the accessory 10 to an unlocked state, so that the cleaning part 200 can rotate relative to the main body 100 in the cleaning slot.

[0070] like Figure 16As shown, the cleaning device of the embodiment of the present invention connects the main body 100 and the cleaning part 200 through the above-mentioned pivot control structure, and the base 300 is further provided with an accessory 10. When the main body 100 and the cleaning part 200 are placed on the base 300, the accessory 10 on the base 300 triggers the locking structure 3 of the pivot control structure, thereby unlocking the locking structure 3 and allowing the cleaning part 200 to rotate relative to the main body 100. The cleaning part 200 is in the cleaning tank, so when cleaning it, since it is rotatable, cleaning will become easier, thereby solving the technical problem in the related art that when the cleaning device is placed on the base, the cleaning part cannot rotate relative to the main body or needs to be permanently bent to achieve rotation, which makes cleaning the cleaning part inconvenient. The reason for this technical problem is that its pivot control structure is not flexible to use. The embodiment of the present invention adopts the above-mentioned pivot control structure that can flexibly control locking and unlocking. The main body 100 and the cleaning part 200 only need to be placed on the base 300 to achieve the rotation unlocking of the cleaning part 200, thereby facilitating cleaning.

[0071] In actual implementation, the base 300 can be designed with corresponding additional functions according to needs, such as charging the body 100, cleaning, disinfecting, drying, etc. of the cleaning part 200.

[0072] In this embodiment, when the cleaning device is in working state, that is, when the body 100, the cleaning portion 200 and the pivot control structure are placed on the base 300, at least a portion of the bottom surface of the cleaning tank is inclined to the horizontal plane.

[0073] By designing at least part of the bottom surface of the cleaning tank to be inclined to the horizontal plane, and combining it with the unlockable and rotatable cleaning part 200, it is beneficial to better soak and clean some structures on the cleaning part 200, such as the roller brush, thereby improving the cleaning effect of the cleaning part 200.

[0074] The following describes the pivot control structure and cleaning device of the present invention in conjunction with a specific embodiment. Figures 1 to 16 As shown, the pivot control structure is applied to a cleaning device, specifically, a floor scrubber, wherein the body 100 and the cleaning part 200 of the floor scrubber are connected by the pivot control structure. According to the relative angle between the two, the two can be divided into an upright state, for example, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 7 、 Figure 8 、 Figure 12 In the state shown in the figure, when the floor scrubber is placed on the ground, the cleaning part 200 is in contact with the ground, and the body 100 is upright on the ground and in a non-upright state, for example Figure 6 and Figure 10According to the state of the locking structure 3, it can be divided into a locking state such as Figure 3 、 Figure 4 、 Figure 6 、 Figure 10 The state shown in FIG, at this time the locking member 32 is in the locked position and the unlocked state, for example Figure 7 、 Figure 8 、 Figure 10 The status displayed in .

[0075] Specifically, if Figure 3 、 Figure 4 and Figure 5 As shown, the floor scrubber is in an upright locked state. When it is placed on the ground, the cleaning portion 200 is in contact with the ground and the body 100 is upright on the ground, thereby facilitating the placement of the floor scrubber.

[0076] like Figure 6 As shown, when the floor scrubber is used, external force is applied to the body 100. When the extrusion force between the first stop block 314 and the second stop block 21 reaches a threshold value, the first stop block 314 passes over the second stop block 21 under the action of deformation or expansion, thereby losing the limiting effect between the two. At this time, the body 100 can be rotated relative to the cleaning part 200, thereby facilitating the use of the floor scrubber.

[0077] like Figure 7 、 Figure 8 、 Figure 9 and Figure 16 As shown, when the cleaning part 200 of the floor scrubber needs to be cleaned or the floor scrubber needs to be charged, the main body structure of the floor scrubber can be placed on the base 300. At this time, the accessory 10 on the base 300 can trigger the locking member 32 of the locking structure 3, thereby unlocking the locking structure 3. At this time, there is no need to apply external force to overcome the resistance between the first stopper 314 and the second stopper 21. The body 100 and the cleaning part 200 can rotate relative to each other, for example, to Figure 10 、 Figure 11 In this embodiment, the bottom surface of the cleaning tank on the base 300 is an inclined surface, so when the cleaning part 200 is placed therein, it will tilt accordingly, thereby better increasing the immersion depth and facilitating the immersion and washing of the roller brush on the cleaning part 200.

[0078] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0079] The pivot control structure of the embodiment of the present invention includes a pivot part, which can be adapted to the accessory 10, and the pivot part includes: a first pivot part 1; a second pivot part 2, which is pivotally connected to the first pivot part 1; a locking structure 3, which has a locked state and an unlocked state; when the locking structure 3 is in the locked state, the locking structure 3 restricts the relative rotation between the first pivot part 1 and the second pivot part 2; when the locking structure 3 is in the unlocked state, the locking structure 3 does not restrict the relative rotation between the first pivot part 1 and the second pivot part 2, or the restricting effect between the first pivot part 1 and the second pivot part 2 is less than that in the unlocked state; wherein, when the pivot part cooperates with the accessory 10, the accessory 10 can trigger the locking structure 3 to switch the locking structure 3 from the locked state to the unlocked state. With the pivot control structure of this structural design, the accessory 10 can trigger the locking structure 3. When the pivot part cooperates with the accessory 10 and the locking structure 3 is in a locked state, the accessory 10 can trigger the locking structure 3 to an unlocked state, thereby enabling the first pivot part 1 and the second pivot part 2 to rotate more flexibly, thereby facilitating related operations on the two pivot parts or the structures connected thereto. For example, when the accessory 10 triggers the locking structure 3 to an unlocked state, the two-part structure connected to the first pivot part 1 and the second pivot part 2 can rotate relatively flexibly, thereby facilitating operations such as cleaning, repair, storage, and maintenance. This effectively improves the flexibility of use of the pivot control structure and solves the technical problem of inflexible use of the pivot structure in the related art.
