[0001] The present disclosure is based on and claims priority to Chinese Patent Application No. 202422162373.0, filed on September 3, 2024, entitled "A cleaning disc and a cleaning device", the entire contents of which are incorporated herein by reference. TECHNICAL FIELD

[0002] The present application relates to the technical field of cleaning devices, and in particular to a cleaning disc and a cleaning device. BACKGROUND

[0003] With the continuous progress of living conditions and technological level, cleaning devices represented by floor cleaning robots have gradually replaced manual cleaning and are widely used in life and work.

[0031] It should be noted that the embodiments in the present application and the technical features in the embodiments can be combined with each other without conflict, and the detailed description in the specific embodiments should be understood as the explanation and illustration of the purpose of the present application, and should not be regarded as improper limitation on the present application.

[0032] In the description of the embodiments of the present application, as shown in FIGS. 1 and 2, the direction in which the arrow X is located is the "circumferential direction of the disc body"; as shown in FIGS. 1 and 7, the direction in which the arrow Y is located is the "axial direction of the disc body" and the "vertical direction", and as shown in FIGS. 3 to 5, the direction in which the arrow Z is located is the "relative direction of the contact part and the mounting part". It should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0033] The embodiments of the present application provide a cleaning disc 10 for a cleaning device, a cleaning piece 20 can be mounted on the cleaning disc 10, and the cleaning piece 20 is used to contact the surface of a cleaning object such as a floor or a table top to achieve cleaning, mopping and other functions.

[0034] Referring to FIGS. 1 and 2, the cleaning disc 10 includes a disc body 11 and a buffer piece 12.

[0035] The disc body 11 is used to connect with the cleaning piece 20, and can be connected with a device body 30 of the cleaning device, so that the cleaning piece 20 and the cleaning disc 10 move with the device body 30.

[0036] The buffer piece 12 includes a mounting part 121, a buffer part 122 and a contact part 123, the mounting part 121 is arranged at the circumferential edge of the disc body 11, the contact part 123 is arranged at the side of the mounting part 121 away from the disc body 11, the contact part 123 is spaced apart from the mounting part 121 to form a buffer space 12a, the buffer part 122 is located in the buffer space 12a and connects the mounting part 121 and the contact part 123, the buffer space 12a includes a first buffer sub-space 122a and a second buffer sub-space 12c, the buffer part 122 surrounds to form the first buffer sub-space 122a, the second buffer sub-space 12c is located at one side of the circumferential direction of the disc body 11 and communicates with the first buffer sub-space 122a, and the buffer part 122 can be elastically deformed in the relative direction of the mounting part 121 and the contact part 123.

[0037] The circumferential edge of the disc body 11 refers to the side of the disc body 11 perpendicular to the relative direction of the disc body 11 and the cleaning piece 20 in the state of being connected with the cleaning piece 20, as shown in FIG. 2.

[0038] The mounting part 121 connects the buffer piece 12 with the disc body 11.

[0039] The contact portion 123 and the mounting portion 121 are spaced apart to form a buffer space 12a. In a process in which the contact portion 123 collides with an external object, such as a table leg, a wall, or the like, in a direction opposite to the mounting portion 121, at least a portion of the contact portion 123 can be deformed to compress the buffer space 12a. In this way, the deformation of the contact portion 123 can absorb the collision energy.

[0040] Referring to FIGS. 3 to 5, the boundary surface 12b shown by the auxiliary line is a division boundary, and the internal space surrounded by the buffer portion 122 is shown as a first buffer sub-space 122a and a second buffer sub-space 12c in communication with the first buffer sub-space 122a.

[0041] It can be understood that, in a state in which the contact portion 123 is subjected to a collision force in a direction opposite to the mounting portion 121, a force transmission path is formed between the mounting portion 121 and the contact portion 123 through the buffer portion 122, so that the collision force is transmitted to the mounting portion 121 through the buffer portion 122, and then to the disc body 11.

[0042] The first buffer sub-space 122a is in communication with the second buffer sub-space 12c on one side in the circumferential direction of the disc body 11, so that the edge of the buffer portion 122 forming an opening of the first buffer sub-space 122a lacks support on both sides in the direction opposite to the mounting portion 121 and the contact portion 123, so that the structural rigidity of the region of the buffer portion 122 in which the first buffer sub-space 122a is provided is lower than that of other regions, so that the region is more likely to deform under the action of the collision force, and the buffer portion 122 can elastically deform in the direction opposite to the mounting portion 121 and the contact portion 123.

[0043] It can be understood that, under the action of the collision force, a portion of the collision energy is converted into elastic potential energy generated by the deformation of the buffer portion 122 itself; after the collision force is removed, the elastic potential energy of the buffer portion 122 is released, and the shape of the buffer portion 122 is restored, so that the buffer portion 122 can continue to play a role in the next collision.

[0044] The cleaning disc 10 in the embodiment of the present application is provided with the first buffer sub-space 122a in the buffer portion 122, so that the contact portion 123 can absorb a portion of the collision energy by deforming itself in the process of being subjected to a collision or extrusion, thereby reducing the collision energy transmitted to the mounting portion 121 and the disc body 11, which is conducive to reducing the probability of damage to the disc body 11 caused by a collision, reducing the risk of abnormality at the connection position of the disc body 11 and the device body 30 of the cleaning device caused by a collision, prolonging the service life of the cleaning disc 10, and reducing the probability of foreign matter entering the first buffer sub-space 122a during the operation of the cleaning device.

[0045] It can be understood that the buffer portion 122 is made of an elastic material, so that the buffer portion 122 can be elastically deformed in the state that the contact portion 123 is subjected to the impact.

[0046] The type of the elastic material used by the buffer portion 122 can be rubber, silica gel, etc.

[0047] In some embodiments, the buffer member 12 is made of an elastic material, that is, the mounting portion 121, the buffer portion 122, and the contact portion 123 are all made of an elastic material, so that the mounting portion 121, the buffer portion 122, and the contact portion 123 can all be elastically deformed in the process that the contact portion 123 is subjected to the impact, thereby facilitating the absorption of more impact energy.

[0048] The specific number of the first buffer sub-space 122a provided by one buffer portion 122 can be one, referring to FIGS. 3 and 4, and can also be multiple, referring to FIG. 5.

[0049] In some embodiments, referring to FIGS. 1 and 2, the first buffer sub-space 122a is open on at least one side of the axial direction of the disk body 11.

[0050] The axial direction of the disk body 11 is perpendicular to the relative direction of the mounting portion 121 and the contact portion 123.

[0051] In this way, it is beneficial to reduce the structural rigidity of the buffer portion 122 in the relative direction of the mounting portion 121 and the contact portion 123, and it is more beneficial to facilitate the elastic deformation of the buffer portion 122 in the relative direction of the mounting portion 121 and the contact portion 123 in the process of the impact.

[0052] In some embodiments, referring to FIGS. 1 and 2, the first buffer sub-space 122a is open on both sides of the axial direction of the disk body 11, that is, the first buffer sub-space 122a penetrates the buffer portion 122 along the axial direction of the disk body 11.

[0053] In this way, it is more beneficial to reduce the structural rigidity of the buffer portion 122 in the relative direction of the mounting portion 121 and the contact portion 123; at the same time, it is also convenient to clean the foreign matter entering the first buffer sub-space 122a after the cleaning disk 10 is used for a long time, thereby reducing the inhibitory effect of the foreign matter on the elastic deformation of the buffer portion 122.

[0054] In some embodiments, referring to FIG. 3, in the projection perpendicular to the relative direction of the mounting portion 121 and the contact portion 123, the projection of the connection region of the buffer portion 122 and the mounting portion 121 is located within the projection range of the first buffer sub-space 122a.

[0055] Thus, no region of the buffer portion 122 extends along a straight line in the relative direction of the mounting portion 121 and the contact portion 123 to connect the mounting portion 121 and the contact portion 123, which further facilitates deformation of the buffer portion 122 in the relative direction of the mounting portion 121 and the contact portion 123.

[0056] In some embodiments, referring to FIG. 3, in a projection perpendicular to the relative direction of the mounting portion 121 and the contact portion 123, the projection of the connecting region of the buffer portion 122 and the contact portion 123 is located within the projection range of the first buffer sub-space 122a.

[0057] Thus, no region of the buffer portion 122 extends along a straight line in the relative direction of the mounting portion 121 and the contact portion 123 to connect the mounting portion 121 and the contact portion 123, which further facilitates deformation of the buffer portion 122 in the relative direction of the mounting portion 121 and the contact portion 123.

[0058] In some embodiments, referring to FIG. 4, in a projection perpendicular to the relative direction of the mounting portion 121 and the contact portion 123, the projection of the connecting region of the buffer portion 122 and the mounting portion 121 and the projection of the connecting region of the buffer portion 122 and the contact portion 123 partially overlap, and a portion of the projection of the overlapping portion is located outside the projection range of the first buffer sub-space 122a.

[0059] Thus, a portion of the buffer portion 122 extends along a straight line in the relative direction of the mounting portion 121 and the contact portion 123 to connect the mounting portion 121 and the contact portion 123, which facilitates reduction of the structural rigidity of the buffer portion 122 and reduces the probability that the contact portion 123 directly contacts the mounting portion 121 during deformation in a collision.

[0060] The specific structural form of the first buffer sub-space 122a is not limited.

[0061] For example, referring to FIG. 3, the buffer portion 122 includes a first connecting sub-portion 1221 and a second connecting sub-portion 1222, the first connecting sub-portion 1221 and the second connecting sub-portion 1222 are connected to each other in the relative direction of the mounting portion 121 and the contact portion 123, and the extension directions of both are inclined to the relative direction of the mounting portion 121 and the contact portion 123, and the first connecting sub-portion 1221 and the second connecting sub-portion 1222 are spaced apart from each other in the relative direction of the mounting portion 121 and the contact portion 123 to form the first buffer sub-space 122a.

[0062] That is, the first connecting sub-portion 1221 and the second connecting sub-portion 1222 form an included angle to jointly form a curved structure, and the concave side of the curved structure forms the first buffer sub-space 122a.

[0063] During the collision, the inclination of the relative direction of the mounting portion 121 and the contact portion 123 of the first connecting sub portion 1221 and the second connecting sub portion 1222 increases, the first connecting sub portion 1221 and the second connecting sub portion 1222 are close to each other along the relative direction of the mounting portion 121 and the contact portion 123, so that the buffer portion 122 is deformed along the relative direction of the mounting portion 121 and the contact portion 123.

[0064] In the projection plane perpendicular to the axial direction of the disc body 11, the projection of the curved structure formed by the first connecting sub portion 1221 and the second connecting sub portion 1222 can be V-shaped or circular arc-shaped.

[0065] In some embodiments, referring to FIGS. 1-3, the extension direction of the first connecting sub portion 1221 and the extension direction of the second connecting sub portion 1222 are both perpendicular to the axial direction of the disc body 11, so that the first buffer sub space 122a is open on both sides of the axial direction of the disc body 11 and on one side of the circumferential direction of the disc body 11.

[0066] In some embodiments, referring to FIG. 3, in the projection perpendicular to the relative direction of the mounting portion 121 and the contact portion 123, the projection of the end of the first connecting sub portion 1221 away from the second connecting sub portion 1222 is located outside the projection range of the connection region of the first connecting sub portion 1221 and the second connecting sub portion 1222.

[0067] In this way, there is no straight line structure between the end of the first connecting sub portion 1221 away from the second connecting sub portion 1222 and the connection region of the first connecting sub portion 1221 and the second connecting sub portion 1222 along the relative direction of the mounting portion 121 and the contact portion 123, thereby facilitating the change of the inclination of the extension direction of the first connecting sub portion 1221 relative to the relative direction of the mounting portion 121 and the contact portion 123 during the collision, so as to realize the elastic deformation of the buffer portion 122.

[0068] In some embodiments, referring to FIG. 3, in the projection perpendicular to the relative direction of the mounting portion 121 and the contact portion 123, the projection of the end of the second connecting sub portion 1222 away from the first connecting sub portion 1221 is located outside the projection range of the connection region of the first connecting sub portion 1221 and the second connecting sub portion 1222.

[0069] In this way, there is no straight line structure between the end of the second connecting sub portion 1222 away from the first connecting sub portion 1221 and the connection region of the first connecting sub portion 1221 and the second connecting sub portion 1222 along the relative direction of the mounting portion 121 and the contact portion 123, thereby facilitating the change of the inclination of the extension direction of the second connecting sub portion 1222 relative to the relative direction of the mounting portion 121 and the contact portion 123 during the collision, so as to realize the elastic deformation of the buffer portion 122.

[0070] In some embodiments, referring to FIG. 3, in a projection perpendicular to the relative direction of the mounting portion 121 and the contact portion 123, the projection of the first connecting sub-portion 1221 away from one end of the second connecting sub-portion 1222 at least partially overlaps the projection of the second connecting sub-portion 1222 away from one end of the first connecting sub-portion 1221.

[0071] In this way, the overall profile formed by the first connecting sub-portion 1221 and the second connecting sub-portion 1222 is smaller along the circumferential dimension of the disc body 11, making the structure of the buffer portion 122 more compact.

[0072] The specific number of the first connecting sub-portion 1221 and the second connecting sub-portion 1222 is not limited.

[0073] In some embodiments, referring to FIG. 5, the number of at least one of the first connecting sub-portion 1221 and the second connecting sub-portion 1222 is multiple, and the first connecting sub-portion 1221 and the second connecting sub-portion 1222 are arranged alternately along the relative direction of the mounting portion 121 and the contact portion 123.

[0074] That is, the buffer portion 122 extends reciprocally and is bent to connect the mounting portion 121 and the contact portion 123, and the buffer portion 122 is provided with multiple first buffer sub-spaces 122a, and the opening directions of two first buffer sub-spaces 122a adjacent along the relative direction of the mounting portion 121 and the contact portion 123 are different.

[0075] In this way, the buffer portion 122 can swing, and under impact in different directions, the buffer portion 122 can produce a larger amplitude of elastic deformation to absorb part of the collision energy.

[0076] It can be understood that the total number of the first connecting sub-portion 1221 and the second connecting sub-portion 1222 can be odd; or even, and the first connecting sub-portion 1221 and the second connecting sub-portion 1222 are arranged in pairs along the relative direction of the mounting portion 121 and the contact portion 123, one of the first connecting sub-portion 1221 and the second connecting sub-portion 1222 is connected to the mounting portion 121, and the other is connected to the contact portion 123.

[0077] In some embodiments, referring to FIG. 3, the number of the first connecting sub-portion 1221 and the second connecting sub-portion 1222 is one, the first connecting sub-portion 1221 is connected to the mounting portion 121, and the first connecting sub-portion 1221 is connected to the contact portion 123.

[0078] In this way, the structure of the buffer portion 122 is simplified, and the manufacturing of the buffer portion 122 is facilitated.

[0079] In the state that the cleaning disc 10 is installed on the cleaning device, the cleaning device can drive the cleaning disc 10 to rotate, and then the cleaning member 20 can rub against the surface of the object to be cleaned, so as to better play the cleaning effect. Therefore, the peripheral side of the cleaning disc 10 can collide with the object.

[0080] The mounting portion 121 can be only wrapped on a part of the peripheral edge of the disc body 11, or can be wrapped on the entire peripheral edge of the disc body 11.

[0081] In some embodiments, referring to FIGS. 1 and 2, the mounting portion 121 and the contact portion 123 are annular structures, and the number of the buffer portions 122 is multiple, and the multiple buffer portions 122 are uniformly arranged along the circumferential direction of the disc body 11.

[0082] Along the circumferential direction of the disc body 11, the distance between any two adjacent buffer portions 122 is the same.

[0083] In this way, the mounting portion 121 can cover any position of the peripheral edge of the disc body 11, so that any position of the circumferential edge of the disc body 11 can be protected by the buffer member 12, and the multiple buffer portions 122 are arranged along the circumferential direction, which is beneficial to the elastic deformation of the buffer portions 122 when the contact portion 123 collides at any position along the circumferential direction.

[0084] In some embodiments, the first buffer sub-space 122a of each buffer portion 122 is open on one side along the circumferential direction of the disc body 11, and the open direction of the first buffer sub-space 122a of any two adjacent buffer portions 122 is opposite to the open direction of the other buffer portion 122.

[0085] That is to say, from the axis of the disc body 11, the open direction of each first buffer sub-space 122a along the circumferential direction is uniformly in the clockwise direction or in the counterclockwise direction.

[0086] In this way, the arrangement of each buffer portion 122 is uniform, which is beneficial to simplify the design and manufacturing process of the buffer member 12, and reduce the production cost.

[0087] In some embodiments, referring to FIG. 1, the buffer portion 122 is completely located inside the buffer space 12a, that is, along the axial direction of the disc body 11, the buffer portion 122 does not protrude from any one of the mounting portion 121 and the contact portion 123, so as to reduce the adverse effects of the elastic deformation of the buffer portion 122 on the absorption of the collision energy when the cleaning disc 10 is installed on the cleaning device and interferes with other components in the cleaning device.

[0088] The embodiment of the present application also provides a cleaning device, referring to FIG. 6 and FIG. 7, the cleaning device comprises a device body 30, a cleaning element 20 and the cleaning disc 10 in any of the foregoing embodiments, the device body 30 is drivingly connected with the disc body 11 to drive the disc body 11 to rotate, the connection position of the device body 30 and the disc body 11 is located at one side of the disc body 11 along the axial direction, and the cleaning element 20 is located at the other side.

[0089] The axial direction of the disc body 11 is the straight line direction where the rotation axis of the disc body 11 is located.
