[0032] In order to make the objectives, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure.

[0033] The terms used in the embodiments of the present disclosure are only for the purpose of describing specific embodiments, and are not intended to limit the present disclosure. The singular forms "a", "the" and "said" used in the embodiments of the present disclosure and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. "Plural" generally includes at least two, and other quantifiers are similar thereto.

[0034] It should be understood that although the terms first, second, third, etc. may be used in the embodiments of the present disclosure for description, these descriptions should not be limited to these terms. These terms are only used to distinguish the described objects. For example, without departing from the scope of the embodiments of the present disclosure, the first may also be referred to as the second, and similarly, the second may also be referred to as the first. In addition, the terms "first", "second", "third", etc. are only for descriptive purposes, and cannot be understood as indicating or implying relative importance.

[0035] In the description of the present disclosure, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0036] It should also be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a commodity or device including a series of elements not only includes those elements but also includes other elements not explicitly listed, or further includes elements inherent to such commodity or device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of additional identical elements in the commodity or device including the said element.

[0037] In the related art, the first component and the second component in the rotating assembly can rotate freely. For example, both the first component and the second component are in a free state when opening or closing, and cannot freely hover at the desired position during the rotation process, which often leads to problems such as pinching hands and inconvenience for users. For example, when the rotating assembly is provided on the flip cover of a dust collection device, etc., since the flip cover cannot hover, it is easy to pinch hands or slap the dust collection device body under the action of gravity, causing abnormal noises and affecting the user experience.

[0038] Therefore, the embodiments of the present disclosure provide a rotating assembly, including: a first component including at least one support frame; a second component including at least one rotating part, the rotating part being capable of rotating relative to the support frame; wherein, the rotating part includes at least one limiting groove configured to enable the second component to hover in the air relative to the first component.

[0039] Each rotating part in the second component of the rotating assembly provided by the present disclosure includes at least one limiting groove, and the limiting groove can enable the second component to hover in the air relative to the first component, thereby facilitating the user to use the cleaning device and the dust collection device at the hovering position, improving the convenience of user use, and also preventing accidents such as pinching hands, thus enhancing the user experience.

[0040] The optional embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0041] The embodiments of the present disclosure provide a rotating assembly. The rotating assembly can be a device, equipment, component or structure with independent functions, or a partial structure of a device, equipment, component or structure with independent functions. This partial structure can often be replaced by means of disassembly, and no limitation is made thereto.

[0042] As an example, the rotating component can be the dust box of the cleaning device. The dust box has a dust box body and a dust box cover, and the two can form a rotating component; the water tank of the cleaning device, the water tank has a water tank body and a water tank cover, and the two can also form a rotating component. It can also be the main body and the cover plate of the dust collection device, and the two can form a rotating component. The clean water tank, sewage tank, dust box, etc. in the dust collection device can all include a main body and a cover body, and the main body and the cover body form a rotating component. Therefore, the rotating component described in this disclosure is not limited to any specific implementation manner, and any combination with a rotating structure is included in the scope covered by this disclosure.

[0043] Specifically, in some embodiments, as Figure 1 shown, the rotating component 100 includes: a first component 10 and a second component 20. The first component 10 and the second component 20 can rotate relative to each other. For example, in the use state, the first component 10 is stationary, and the second component 20 can rotate relative to the first component 10, and vice versa; the first component 10 can be a device with independent functions or a partial structure of a device with independent functions, such as a dust box body; the second component 20 can be a device with independent functions or a partial structure of a device with independent functions, such as a dust box cover. The first component 10 includes at least one support frame 11. For example, the first component 10 includes 2-4 support frames 11; the support frame 11 can be a detachable or non-detachable partial structure of the first component 10. For example, the support frame 11 is detachably fixed to the edge position of the first component 10 by screws to form a support frame with a hollow bottom that can play a supporting role; the support frame 11 can include a plurality of reinforcing ribs to enhance its rigidity. The second component 20 includes at least one rotating part 21, and the number of rotating parts 21 corresponds to the number of support frames 11, for example, it is also 2-4; the support frame 11 or a part thereof can rotate relative to the outer peripheral surface of the rotating part 21, for example, rotate within a range of 0-180 degrees; wherein, the rotating part 21 includes at least one limiting groove 211, and the limiting groove 211 is configured to make the second component 20 hover in the air relative to the first component 10. Optionally, the rotating part includes at least two limiting grooves, and the limiting grooves are configured to make the second component hover at different positions relative to the first component. Optionally, the different positions include a first position where the first component 10 and the second component 20 are in a closed state, and a second position where the first component 10 and the second component 20 are in an open state. In this embodiment, by providing one, two or more limiting grooves 211, the second component 20 can hover at a certain position or different positions relative to the first component 10, so as to facilitate the user to operate at the hovering position, improve the convenience of user use, and also prevent accidents such as pinching hands, thus improving the user experience.

[0044] In some embodiments, asFigure 1 As shown, the support frame 11 has a limit protrusion 111. In response to the limit protrusion 111 sliding into the limit groove 211, the second component 20 hovers relative to the first component 10. The limit protrusion 111 is in a relatively fixed state along with the first component 10. During the rotation of the second component 20, the limit protrusion 111 slides along the outer peripheral surface of the rotating part 21. After the limit protrusion 111 slides into the limit groove 211, the limit protrusion 111 and the limit groove 211 are locked within a certain force range, so that the second component 20 can hover relative to the first component 10 until an external force exceeds the certain force range and causes the limit protrusion 111 to slide out of the limit groove 211, enabling the limit protrusion 111 to continue sliding along the outer peripheral surface of the rotating part 21 until it slides into the next limit groove 211 and hovers again. The limit protrusion 111 can be a single or multiple discrete spherical local protrusions, or a cylindrical local protrusion, or an arc protrusion with an irregular curvature; the bending structure of the limit protrusion 111 corresponds to and fits with the limit groove 211. For example, the curvature of the limit protrusion 111 is approximately the same as that of the limit groove 211 to achieve stable rotational positioning.

[0045] In some embodiments, as Figure 1 and Figure 2 shown, the limit groove 211 is an arc structure. The arc structure extends axially to form an arc groove; the limit groove 211 can be a continuous arc groove, or one or more discrete arc or spherical grooves; optionally, the depth of the arc structure is 1 / 2 - 1 / 3 of the radius of the circle where the arc structure is located. The curvature of the arc structure cannot be too large to avoid jamming with the limit protrusion 111 and affecting the relative movement of the first component 10 and the second component 20; at the same time, the curvature of the arc structure cannot be too small to avoid too small a clamping force with the limit protrusion 111 and being unable to achieve effective hovering. Further, a plurality of rough structures, such as rough stripes or rough particles, can be provided on the surface of the arc structure to increase the friction between the limit protrusion 111 and the limit groove 211 and improve the stability of the second component 20 hovering relative to the first component 10. Optionally, a chamfer can be provided on the upper edge part of the limit groove 211 to facilitate the sliding of the limit protrusion 111 into or out of the limit groove 211.

[0046] ​In some embodiments, the number of the limiting grooves 211 is 1 - 5, for example, it can be 2, 3, or 4. The 2 - 5 limiting grooves 211 are evenly distributed on the outer periphery of the rotating part 21. Among them, when the number of the limiting grooves 211 is 1, when the second component 20 rotates relative to the first component 10 until the limiting protrusion 111 and the limiting groove 211 are engaged, it hovers in the air. When the number of the limiting grooves 211 is 2, the interval range can be, for example, approximately 90 degrees, so that the second component 20 hovers near 0 degrees and 90 degrees relative to the first component 10. Among them, 0 degrees can be set as the buckling position of the second component 20 relative to the first component 10, and 90 degrees can be set as the opening position of the second component 20 relative to the first component 10. The normal use of the user can be guaranteed at these two positions. When the number of the limiting grooves 211 is more than 2, such as 3 or 4, the redundant limiting grooves 211 can be evenly distributed between 0 degrees and 90 degrees so that it hovers at the positions between 0 degrees and 90 degrees. When the limiting protrusion 111 slides through the limiting grooves 211 in sequence, there is an opportunity to hover in any one of the limiting grooves 211. When the user does not need to hover at the corresponding position, an external force is applied again to make it hover at the position where hovering is required.

[0047] In some embodiments, as Figure 1 and Figure 2 shown, the second component 20 is connected to the rotating part 21 through a rotating arm 23. The rotating arm 23 is an arc-shaped or U-shaped structure for easy rotation. Optionally, the rotating arm 23 is a hollow structure to reduce the weight and increase the rotational flexibility. The rotating part 21 is generally located at the end of the rotating arm 23.

[0048] In some embodiments, as Figure 1 and Figure 2 shown, the second component 20 further includes at least one rotating shaft 22. The number of the rotating shafts 22 corresponds to the number of the rotating parts 21. The rotating shafts 22 can be fixed on the first component 10, and then the rotating shafts 22 are inserted into the rotating parts 21 so that the rotating parts 21 can rotate around the rotating shafts 22.

[0049] In some embodiments, the first component 10 includes at least one notch part 12 configured to accommodate structural parts such as the support frame 11, the rotating part 21, and the rotating shaft 22, so that the rotating part 21 can freely rotate in the notch part 12.

[0050] In some embodiments, as Figure 3 and Figure 4As shown, the rotating assembly 100 further includes an elastic member 30. The elastic member 30 is disposed between the first assembly 10 and the second assembly 20. For example, the elastic member 30 can be sleeved outside the rotating shaft 22. The elastic member 30 can be a torsion spring, a shrapnel, etc. Taking the torsion spring as an example, one end of it is clamped to the first assembly 10, such as in the groove on the inner sidewall of the notch portion 12, and the other end is clamped to the second assembly 20, such as in the groove at the end of the rotating arm 23, as Figure 4 shown. Among them, the elastic member 30 can be in a tensioned state at the first position and in a relaxed state at the second position. For example, it is in a tensioned state at the first position, so that the second assembly 20 is tightly engaged with the first assembly 10 under the action of the elastic member 30. When the second assembly 20 rotates to the second position, the elastic member 30 is in a relaxed state at the second position to facilitate the opening of the second assembly 20. Vice versa, which will not be elaborated here.

[0051] In some other specific embodiments, the rotating assembly 100 is applied as a flip assembly of a cleaning device or a dust collecting device. Among them, the first assembly 10 can be the main body structure of the cleaning device or the dust collecting device, which is fixed relative to the flip cover during use, and the second assembly 20 can be the flip cover on the cleaning device or the dust collecting device body, and the free hovering of the flip cover is realized through the structure of the flip assembly. Specifically, as Figures 5 - 6As shown in the figure, the dust collection device includes a main body structure, which is the first component 10 described in the above embodiment. The main body structure includes the structures or components for the dust collection device to realize functions such as dust collection and charging, which will not be elaborated here. Among them, the main body structure includes two support frames, and the two support frames are respectively rotatably connected to the rotating parts 21 on the cover plate (i.e., the second component 20 described in the above embodiment). When the user opens the cover plate, the cover plate can be hovered at an open position close to 90 degrees (such as 85 degrees - 92 degrees) according to needs. At this time, the limit protrusion 111 cooperates with the limit groove 211 to realize the limit and maintain the open state of the cover plate, so that the cover plate will not freely fall back onto the main body of the dust collection device due to the user releasing the hand, thus causing abnormal noises when the cover plate impacts the main body of the dust collection device, nor will it pinch the hand and affect the user experience. When the cover plate is closed, the cover plate is hovered at a closed position close to 0 degrees (such as 0 degrees - 5 degrees). At this time, the limit protrusion 111 cooperates with another limit groove 211 to realize the limit and maintain the closed state of the cover plate. In addition, when more limit grooves 211 are provided, the cover plate can be hovered at any position between close to 0 degrees and 90 degrees, so that the cover plate can be in a semi-open state without freely falling back onto the main body of the dust collection device, enhancing the flexibility of user use. Optionally, as described in the above embodiment, an elastic member can be added so that when the cover plate is hovered at a closed position close to 0 degrees, a damping effect is further generated by the tension force of the elastic member to avoid impact noise caused by the rapid buckling of the cover plate. And when the cover plate is hovered at an open position close to 90 degrees, the elastic member is in a relaxed state and will not apply a force in the direction of falling back onto the main body of the dust collection device, facilitating the use of the user.

[0052] The rotating assembly provided by the embodiment of the present disclosure can be applied to a cleaning device and a dust collection device. One of the components of the rotating assembly includes at least one rotating part, and each of the rotating parts includes at least one limit groove. The limit groove can enable the component to hover in the air relative to another component, so as to facilitate the user to use the cleaning device and the dust collection device at the hovering position. It avoids the occurrence of accidents such as pinching hands or abnormal noises caused by freely falling back onto the main body of the cleaning device and the dust collection device when the cover plate is opened. In addition, through the damping effect of the elastic member, when the cover plate is buckled on the main body of the cleaning device and the dust collection device, no impact noise will be generated. Since the elastic member is arranged in the rotating shaft of the rotating part, it does not occupy extra space and can cooperate with the limit groove to realize the limit function, improving the user experience.

[0053] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts among the various embodiments can be referred to each other. For the system or device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the description of the method part.

[0054] The above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them; although the present disclosure has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present disclosure.
