Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the following detailed description of the embodiments of the present application will be given with reference to the accompanying drawings.

When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the accompanying claims.

Referring to fig. 1, a cleaning apparatus 1 is provided in the embodiment of the present application, and the cleaning apparatus 1 may be a dust collector, a floor scrubber, a steam mop, etc., which is not limited thereto.

The cleaning device 1 comprises a floor brush structure 10 and a main body 20 connected to the floor brush structure 10. The floor brush structure 10 is used for walking on dust accumulation areas such as the ground to clean garbage on the dust accumulation areas; the main body 20 is provided with a dust collecting cavity (not shown in the figure), and the main body 20 is used for collecting the garbage cleaned by the floor brush structure 10 in the dust collecting cavity so as to perform centralized treatment on the garbage.

Specifically, referring to fig. 1 and 2, the floor brush structure 10 includes a floor brush 11 and a joint assembly 12, wherein the floor brush 11 is configured to walk over a dust area to clean debris on the dust area; the joint assembly 12 is used to connect the floor brush 11 with the main body 20. Wherein, joint assembly 12 has the freedom of movement in a plurality of directions to make brush 11 have the freedom of movement in a plurality of directions for main part 20, so, the user can change the relative position of brush 11 and main part 20 when using cleaning device 1 according to the demand, realizes diversified, multi-angle cleanness, reduces the frequency of bending over, changing the gesture when the user uses, promotes cleaning device 1's use convenience. The dust accumulation area to be cleaned by the cleaning device 1 may be a plane area, a slope area, a cambered area, or the like, which is not limited.

Further, referring to fig. 2 to 5, the joint assembly 12 includes a first connecting member 121, a second connecting member 122 and a third connecting member 123.

Referring to fig. 2, the first link 121 is connected to the ground brush 11, and the second link 122 is connected to the first link 121 and rotatable about the first axis x with respect to the first link 121. Referring to fig. 3, a third link 123 is connected to the second link 122 and is rotatable about the second axis y relative to the second link 122, the third link 123 being for connection with the main body 20 of the cleaning device 1. In this way, the third connecting piece 123 can rotate around the first axis x and around the second axis y relative to the first connecting piece 121, so that the main body 20 can rotate around the first axis x and around the second axis y relative to the floor brush 11, the diversity of relative position conversion between the main body 20 and the floor brush 11 when the user uses the cleaning device 1 is realized, the cleaning of dust accumulation areas such as corners, gaps and the like by the cleaning device 1 is realized, and the cleaning effect is improved.

The first axis x is disposed at an angle with the walking surface p of the ground brush 11, and the distance from the first axis x to the walking surface p is gradually increased from the joint assembly 12 to the direction away from the ground brush 11. Since the user generally holds the hand-held lever 22 on the main body 20 and the holding part is located above the floor brush 11 and the joint assembly 12 when using the cleaning device 1, the first axis x is designed to gradually rise in a direction from one end of the joint assembly 12 connected with the floor brush 11 to the other end, which is beneficial for the user to easily control the hand-held lever 22 so that the main body 20 rotates around the first axis x relative to the floor brush 11, thereby improving the flexibility of position switching of the floor brush 11 relative to the main body 20 and improving the operation convenience of the user using the cleaning device 1.

The running surface p of the floor brush 11 is a surface of the floor brush 11 that contacts the dust accumulation area when the cleaning apparatus 1 is in use. For example, the floor brush 11 includes a plurality of rollers 117, and a surface of the plurality of rollers 117 for contacting the dust accumulation area when the cleaning apparatus 1 is in use constitutes a running surface p of the floor brush 11.

Optionally, the acute angle between the first axis x and the walking surface p is a first acute angle θ1, where the first acute angle θ1 is greater than or equal to 3 ° and less than or equal to 20 °, so as to optimize the use effect of the cleaning device 1. For example, the first acute angle θ1 may be 3 °, 8 °, 12 °, 16 °, 20 °, and so on. If the first acute angle θ1 is smaller than 3 °, the user may operate the hand-held lever 22 to make the rotation of the main body 20 about the first axis x relative to the floor brush 11 less convenient, and a jerk is easily generated, and if the first acute angle θ1 is larger than 20 °, a problem of tilting easily occurs at an end of the main body 20 connected to the floor brush 11 during the rotation of the main body 20 about the first axis x relative to the floor brush 11.

Wherein the second axis y is perpendicular to the first axis x, so that a user can conveniently operate the hand lever 22 to rotate the main body 20 around the second axis y relative to the floor brush 11 when using the cleaning apparatus 1, and change the pitch angle of the main body 20 relative to the floor brush 11. Meanwhile, the handle 22 can be controlled so that the rotation of the main body 20 around the first axis x relative to the ground brush 11 and the rotation of the main body 20 around the second axis y relative to the ground brush 11 are not mutually interfered, and the rotation smoothness in two degrees of freedom directions is improved. The extending direction of the hand-held lever 22 may be perpendicular to the second axis y.

It should be noted that, due to factors such as manufacturing errors and assembly errors, it is generally difficult to achieve that the second axis y is exactly perpendicular to the first axis x, in this embodiment of the present application, as long as the second axis y is considered to be perpendicular to the first axis x within an error allowable range, where the error allowable range can be adjusted in combination with actual requirements, and this is not limited; for example, the error allowable range may be ±2°, or the like.

When the second axis y is not perpendicular to the first axis x, the end of the brush 11 is tilted in the direction of the second axis y easily during the process of manipulating the handle 22 to rotate the main body 20 around the second axis y relative to the brush 11.

The second connecting piece 122 is connected to the first connecting piece 121 and is rotatable about the first axis x relative to the first connecting piece 121, and at this time, the connection mode between the second connecting piece 122 and the first connecting piece 121 may be a socket connection, or may be a connection through a rotating shaft, which is not limited specifically. In the following, the second connecting member 122 is sleeved with the first connecting member 121 by way of example, where the second connecting member 122 is sleeved with the first connecting member 121, and the second connecting member 122 may be sleeved on the periphery of the first connecting member 121 around the first axis x, or, in combination with fig. 4 and fig. 5, the first connecting member 121 is sleeved on the periphery of the second connecting member 122 around the first axis x, or, a sleeve is sleeved on the periphery of the first connecting member 121 around the first axis x and sleeved on the periphery of the second connecting member 122.

Specifically, the first connecting member 121 may include a first connecting portion 1211 disposed about the first axis x, and the second connecting member 122 may include a second connecting portion 1221 disposed about the first axis x, and the first connecting portion 1211 is sleeved with the second connecting portion 1221 to thereby enable the sleeving of the first connecting member 121 and the second connecting member 122.

To achieve the first connection member 121 mounted on the floor brush 11, the first connection portion 1211 of the first connection member 121 is disposed about the first axis x, and the orientation of the first connection member 121 with respect to the floor brush 11 may be adjusted to achieve the first connection portion 1211 disposed about the first axis x when the first connection member 121 is assembled with the floor brush 11; of course, the first positioning portion (not shown in the drawings) may be directly disposed on the ground brush 11, so that when the first connecting piece 121 is mounted on the first positioning portion on the ground brush 11, the first connecting portion 1211 is disposed around the first axis x, so as to reduce the alignment difficulty during assembly and improve the assembly efficiency.

Optionally, referring to fig. 4 and 5, the first connecting piece 121 may also include a third connecting portion 1212, where the third connecting portion 1212 is used to connect the first connecting portion 1211 to the ground brush 11, and the first connecting piece 121 is designed to include the first connecting portion 1211 and the third connecting portion 1212, so that the assembly alignment requirement when the first connecting portion 1211 is connected to the ground brush 11 can be transferred to the design requirement on the relative positions of the first connecting portion 1211 and the second connecting portion 1221 when the first connecting piece 121 is manufactured, and the manufacturing process is relatively mature due to the relatively simple structure of the first connecting piece 121, so that the design difficulty is low.

Specifically, the third connecting portion 1212 may be provided with a pair of abutting surfaces 1213, and an acute angle between the abutting surfaces 1213 and the first axis x may be complementary to an acute angle between the first axis x and the walking surface p. Thus, when the first connecting piece 121 is assembled with the ground brush 11, the abutting surface 1213 of the third connecting portion 1212 is perpendicular to the walking surface p, so that the first connecting portion 1211 is ensured to be arranged around the first axis x, and the assembling alignment difficulty when the first connecting piece 121 is connected with the ground brush 11 can be reduced.

Further, referring to fig. 2, the ground brush 11 may be provided with a second positioning portion 112, so that the abutting surface 1213 of the third connecting portion 1212 can be perpendicular to the walking surface p when the third connecting portion 1212 is connected to the second positioning portion 112. Referring to fig. 6, the second positioning portion 112 may be annular, the abutting surface 1213 of the third connecting portion 1212 may abut against the second positioning portion 112 and the third connecting portion 1212 may be provided with an extension portion extending toward the inside of the second positioning portion 112, so as to enhance the connection reliability between the third connecting portion 1212 and the second positioning portion 112.

It should be noted that, the rotatable angle of the second connecting member 122 about the first axis x relative to the first connecting member 121 may be any angle, for example, the rotatable angle is greater than or equal to 30 ° and less than or equal to 180 °; specifically, the rotatable angle may be 30 °, 60 °, 90 °, 120 °, 180 °, or the like, which is not limited thereto.

Optionally, the rotatable angle of the second connecting member 122 with respect to the first connecting member 121 about the first axis x is 90 °, so that the rotatable angle of the ground brush 11 with respect to the main body 20 about the first axis x is sufficiently large and the rotation operation is convenient.

It should be noted that the rotatable angle of the second connecting member 122 about the first axis x with respect to the first connecting member 121 may be substantially symmetrical about a first plane, wherein the first plane is substantially perpendicular to the walking plane p and the first axis x is located in the first plane, so that the rotatable angle of the second connecting member 122 about the first axis x with respect to the first connecting member 121 is symmetrically distributed on opposite sides of the first plane, so as to promote smoothness of the cleaning of the plurality of areas of the floor brush 11 by the user manipulating the hand lever 22 at the edge rotation angle. For example, when the rotatable angle of the second link 122 with respect to the first link 121 about the first axis x is 90 °, the rotatable angle of the second link 122 with respect to the first link 121 about the first axis x is 45 °, and the rotatable angle of the second link 122 with respect to the first link 121 about the first axis x is 45 ° on the other side of the first plane.

Optionally, in connection with fig. 7, one of the first and second connection members 121, 122 is provided with a guide slot 1222, the other of the first and second connection members 121, 122 is provided with a guide block 1214, the guide slot 1222 extends about the first axis x, and the guide block 1214 is located within the guide slot 1222 and is slidable within the guide slot 1222. The guide slots 1222 and the guide blocks 1214 are configured to guide the relative rotation of the first and second links 121, 122 such that the first link 121 is rotatable about the first axis x relative to the second link 122.

Further, the central angle corresponding to the guide groove 1222 may be matched to the rotatable angle of the second connector 122 about the first axis x relative to the first connector 121. For example, the guide slot 1222 may correspond to a central angle of 90 °, such that the guide block 1214 may be rotatable within the guide slot 1222 about the first axis x by approximately 90 °, and such that the second connector 122 may be rotatable relative to the first connector 121 about the first axis x by approximately 90 °. Thus, by adjusting the central angle corresponding to the guiding slot 1222, the rotatable angle of the second connecting piece 122 around the first axis x relative to the first connecting piece 121 can be changed, which is convenient for design.

The number of the guide grooves 1222 may be one or more. When the number of the guide slots 1222 may be plural, the plural guide slots 1222 are sequentially disposed around the first axis x, the number of the guide blocks 1214 is equal to the number of the guide slots 1222, and a guide block 1214 is correspondingly disposed in each guide slot 1222 to promote rotation stability of the second connecting member 122 relative to the first connecting member 121 around the first axis x.
