[0015] In some embodiments of this utility model, the end face of the outer shell near the brush head and the end face of the first mating part near the brush head are both provided with the first limiting part.

[0026] In some embodiments of this utility model, the brush handle is provided with a connecting part for detachable connection with the brush head, and the cleaning brush also includes another brush head detachably connected to the connecting part, the other brush head being rotatable in any direction relative to the brush handle.
[0027] In some embodiments of this utility model, a brush holder is also included, wherein the brush holder is provided with a storage cavity for storing the brush head and a storage cavity for storing the other brush head.
[0028] The cleaning brush provided in this embodiment of the utility model includes a handle and a brush head connected to one end of the handle, and further includes a limiting structure; the handle includes at least a portion of an outer surface with a non-circular cross-section, and the limiting structure is disposed on the brush head and abuts against the non-circular outer surface to restrict the brush head from rotating circumferentially along the handle; or, the limiting structure includes a first limiting part and a second limiting part, the first limiting part being disposed on the end face of the handle near the brush head, and the second limiting part being disposed on the brush head, the first limiting part and the second limiting part cooperating to restrict the brush head from rotating circumferentially along the handle; or, The brush head is clamped / hooked to one end of the brush handle. The limiting structure includes a first limiting part and a second limiting part. The first limiting part is disposed on the outer surface of the brush handle, and the second limiting part is disposed on the brush head. The first limiting part and the second limiting part cooperate to restrict the brush head from rotating circumferentially along the brush handle. It can be seen that the cleaning brush provided by this utility model embodiment can restrict the brush head from rotating circumferentially along the brush handle because the limiting structure can restrict the brush head from slipping relative to the brush handle when the brush head is subjected to a force along the circumferential direction of the brush handle, thereby avoiding the problem of poor cleaning effect of the cleaning brush along the circumferential direction of the brush handle.

[0040] Reference Figures 1 to 6This utility model provides a cleaning brush, including a handle 1 and a brush head 2 connected to one end of the handle 1, and also includes a limiting structure 3; the handle 1 includes an outer surface A with at least a portion of its cross-section being non-circular, such as a rectangle, square, triangle, ellipse, oblong, other unlisted polygons, or other unlisted non-circular shapes, etc.; the limiting structure 3 is disposed on the brush head 2 and abuts against the non-circular outer surface A to restrict the brush head 2 from rotating circumferentially along the handle 1; or, the limiting structure 3 includes a first limiting part 31 and a second limiting part 32. The first limiting part 31 is provided on the end face of the brush handle 1 near the brush head 2, and the second limiting part 32 is provided on the brush head 2. The first limiting part 31 and the second limiting part 32 cooperate to restrict the brush head 2 from rotating circumferentially along the brush handle 1; or, the brush head 2 is clamped / hooked to one end of the brush handle 1. The limiting structure 3 includes the first limiting part 31 and the second limiting part 32. The first limiting part 31 is provided on the outer side of the brush handle 1, and the second limiting part 32 is provided on the brush head 2. The first limiting part 31 and the second limiting part 32 cooperate to restrict the brush head 2 from rotating circumferentially along the brush handle 1.
[0041] The cleaning brush provided in this embodiment of the utility model includes a handle 1 and a brush head 2 connected to one end of the handle 1, and also includes a limiting structure 3; the handle 1 includes an outer surface A with at least a portion of its cross-section being non-circular, and the limiting structure 3 is disposed on the brush head 2 and abuts against the non-circular outer surface A to restrict the brush head 2 from rotating circumferentially along the handle 1; or, the limiting structure 3 includes a first limiting part 31 and a second limiting part 32, the first limiting part 31 being disposed on the end face of the handle 1 near the brush head 2, and the second limiting part 32 being disposed on the brush head 2, the first limiting part 31 and the second limiting part 32 cooperating to restrict the brush head 2 from rotating circumferentially along the handle 1; or, the brush head 2 The clamping / hooking connection is attached to one end of the brush handle 1. The limiting structure 3 includes a first limiting part 31 and a second limiting part 32. The first limiting part 31 is disposed on the outer side of the brush handle 1, and the second limiting part 32 is disposed on the brush head 2. The first limiting part 31 and the second limiting part 32 cooperate to restrict the brush head 2 from rotating circumferentially along the brush handle 1. It can be seen that the cleaning brush provided in this embodiment of the utility model can restrict the brush head 2 from rotating circumferentially along the brush handle 1 because the limiting structure 3 can restrict the brush head 2 from slipping relative to the brush handle 1 when subjected to a force along the circumferential direction of the brush handle 1, thereby avoiding the problem of poor cleaning effect of the cleaning brush along the circumferential direction of the brush handle 1.
[0042] In addition, the first limiting part 31 is provided on the end face of the brush handle 1 near the brush head 2 or on the outer surface of the brush handle 1. Both are provided on the outer surface of the brush handle 1 and are not provided inside the brush handle 1. This not only reduces the processing difficulty of the first limiting part 31, but also facilitates the docking of the first limiting part 31 and the second limiting part 32, making it convenient for users to operate.
[0043] Furthermore, refer to Figures 3 to 6The brush handle 1 includes a housing 11 and a first mating part 12 disposed within the housing 11. The brush head 2 is provided with a second mating part 21. The first mating part 12 and the second mating part 21 cooperate to connect the brush head 2 to one end of the brush handle 1. When the limiting structure 3 includes a first limiting part 31 and a second limiting part 32, the first limiting part 31 may be disposed on the outer side of the housing 11 (not shown in the figure) or on the end face of the housing 11 near the brush head 2 (e.g., ...). Figure 3 (as shown) and the end face of the first mating part 12 near the brush head 2 (as shown) Figure 3 At least one of the following (shown); when the limiting structure 3 is provided on the brush head 2, the outer shell 11 includes at least a portion of an outer surface A with a non-circular cross section, and the limiting structure 3 provided on the brush head 2 abuts against the non-circular outer surface A provided on the outer shell 11, which can restrict the brush head 2 from rotating circumferentially along the brush handle 1.
[0044] The first mating part 12 and the second mating part 21 can be mated to allow the brush head 2 to be clamped / hooked to one end of the brush handle 1, thus facilitating the connection and separation of the brush head 2 and the brush handle 1.
[0045] In some embodiments of this utility model, the first mating part 12 includes a plurality of clamping members B, and the second mating part 21 is the clamped member. The plurality of clamping members B can be gathered together to clamp the clamped member in the clamping cavity C, so that the brush head 2 is clamped and connected to one end of the brush handle 1. The plurality of clamping members B can be dispersed to release the clamped member from the clamping cavity C, so that the brush head 2 and the brush handle 1 are separated. The first limiting part 31 is provided on the outer side of the outer shell 11 (not shown in the figure) and on the end face of the outer shell 11 near the brush head 2 (e.g., Figure 3 (As shown), the gap D between adjacent clamping members B near the end face of brush head 2 and adjacent to clamping cavity C (as shown) Figure 3 As shown), and at least one of the following: the end face of the clamping member B near the brush head 2 (not shown in the figure);
[0046] In some other embodiments of this utility model, the first mating part 12 includes a bowl-shaped clamping member (not shown in the figure), and the second mating part 21 is the clamped member. The clamped member is forcefully inserted into the bowl-shaped clamping member B from the opening of the bowl-shaped clamping member B, or forcefully pulled out from the opening of the bowl-shaped clamping member B, which can also realize the connection and separation of the brush head 2 and the brush handle 1.
[0047] In the third embodiment of this utility model, the second mating part 21 includes a bowl-shaped clamping member B, and the first mating part 12 is the clamped member. The clamped member is forcefully inserted into the bowl-shaped clamping member B from the opening of the bowl-shaped clamping member B, or forcefully pulled out from the opening of the bowl-shaped clamping member B, which can also realize the connection and separation of the brush head 2 and the brush handle 1.
[0048] In the fourth embodiment of this utility model, the second mating part 21 includes a plurality of clamping members B, the first mating part 12 is the clamped member, the plurality of clamping members B can be gathered together to clamp the clamped member in the clamping cavity C so that the brush head 2 is clamped and connected to one end of the brush handle 1, the plurality of clamping members B can be dispersed to release the clamped member from the clamping cavity C so that the brush head 2 and the brush handle 1 are separated.
[0049] The hook connection described above can be achieved by one of the first mating part 12 and the second mating part 21 including a hook (not shown in the figure) and the other including a hanging hole (not shown in the figure), with the hook hanging in the hanging hole, thereby realizing the hook connection.
[0050] In order to improve the effect of restricting the brush head 2 from rotating around the brush handle 1, there are multiple first limiting parts 31 in this embodiment. The multiple first limiting parts 31 are evenly distributed around the brush handle 1. By cooperating with the second limiting parts 32 on the brush head 2, the effect of restricting the brush head 2 from rotating around the brush handle 1 can be improved.
[0051] Similarly, to better restrict the brush head 2 from rotating circumferentially along the brush handle 1, refer to... Figure 3 In this embodiment, the end face of the outer shell 11 near the brush head 2 and the end face of the first mating part 12 near the brush head 2 are both provided with a first limiting part 31. The second limiting part 32 cooperates with the first limiting part 31 on the outer shell 11 and the first limiting part 31 on the first mating part 12 to restrict the brush head 2 from rotating circumferentially along the brush handle 1. In this embodiment, the second limiting part 32 cooperates with two first limiting parts 31. Compared with the embodiment that only cooperates with one first limiting part 31, the limiting effect of this embodiment is better.
[0052] Specifically, the first limiting part 31 is one of the groove and the protrusion, and the second limiting part 32 is the other of the groove and the protrusion. The protrusion is fitted into the groove to restrict the brush head 2 from rotating circumferentially along the brush handle 1.
[0053] The first limiting part 31 and the second limiting part 32 can also be other structures that can cooperate with each other to limit the brush handle and the brush head, such as a magnetic structure. When it is a magnetic structure, the first limiting part 31 is one of the adsorbing member and the adsorbed member, and the second limiting part 32 is the other of the adsorbing member and the adsorbed member.
[0054] In some embodiments of this utility model, reference is made to Figure 3 and Figure 5 There are multiple limiting structures 3. When the non-circular outer surface A abuts against the multiple limiting structures 3 respectively, the angle of the brush handle 1 relative to the brush head 2 along its own circumference is different. In this way, the other angles of the brush handle 1 relative to the brush head 2 along its own circumference can also enable the brush handle 1 to cooperate with the limiting structure 3 on the brush head 2, with less restriction on the angle of the brush handle 1, which can facilitate the connection between the brush handle 1 and the brush head 2.
[0055] Reference Figure 5 The limiting structure 3 is a limiting groove. The centers of multiple limiting grooves coincide and the multiple limiting grooves are staggered. The non-circular outer surface A can be inserted into multiple limiting grooves and abut against the inner surface of the limiting grooves to restrict the brush head 2 from rotating around the brush handle 1. Thus, compared with the embodiment where the centers of multiple limiting grooves do not coincide, in this embodiment, the non-circular outer surface A on the brush handle 1 can be inserted into any limiting groove by rotating it in the same position. Since there is no need to move the position of the brush handle 1, only rotation is required, which also facilitates the connection between the brush handle 1 and the brush head 2.
[0056] Too many limiting grooves will increase the difficulty of production. Therefore, the number of limiting grooves should not be too many. In this embodiment, it is preferable to have two limiting grooves, and the length directions of the two limiting grooves are perpendicular to each other. In this way, not only can the problem of increased production difficulty be avoided, but also the user can successfully align the brush handle 1 with the limiting groove by rotating it less than 90 degrees. This also facilitates the connection between the brush handle 1 and the brush head 2.
[0057] To form the two limiting grooves that coincide in center and are perpendicular in length direction, in some embodiments of this utility model, a cross-shaped groove can be directly provided on the brush head 2. The horizontal and vertical grooves of the cross-shaped groove are the two limiting grooves. In other embodiments of this utility model, refer to... Figure 5 The brush head 2 is provided with four limiting blocks 33, which are arranged in two rows and two columns. A limiting groove is formed between the surfaces of the two rows of limiting blocks 33 that are close to each other, and another limiting groove is formed between the surfaces of the two columns of limiting blocks 33 that are close to each other.
[0058] To facilitate the brush handle 1 entering the two limiting slots, refer to... Figure 6 In this embodiment, each limiting block 33 is also provided with a guide surface E for guiding the brush handle 1 into the two limiting grooves respectively. Since the guide surface E is provided, even if the non-circular outer surface A on the brush handle 1 is not aligned with the limiting groove, it can still be guided into the limiting groove by the guide surface E, thereby facilitating the connection between the brush handle 1 and the brush head 2.
[0059] Reference Figure 4 and Figure 5 The brush head 2 is provided with a socket 22. When the brush head 2 is connected to one end of the brush handle 1, one end of the brush handle 1 is inserted into the socket 22. Due to the insertion and engagement of the brush handle 1 and the socket 22, the brush head 2 will not swing, thus avoiding the problem of poor brushing effect caused by the swinging of the brush head 2.
[0060] In the above embodiments, water may inevitably enter the socket 22. To avoid the problem of water causing odor inside the socket 22, refer to... Figure 5 and Figure 6In this embodiment, a drain hole 23 is provided in the socket 22, so that water can be drained through the drain hole 23 to avoid the problem of water odor in the socket 22.
[0061] When the brush head 2 is connected to one end of the brush handle 1, the limiting structure 3 is located inside the insertion hole 22. Thus, compared with the implementation where the limiting structure 3 is located outside the insertion hole 22, this embodiment can avoid the limiting structure 3 occupying space outside the insertion hole 22, and at the same time, it can avoid the problem of the limiting structure 3 causing the cleaning brush to have an unsightly appearance.
[0062] The brush head 2 can be a disposable cotton / sponge brush head, or it can include a bristle carrier 24 and bristles 25 disposed on the bristle carrier 24. The bristles 25 can be bristles made by a bristle implantation process, or silicone bristles, or both implanted bristles and silicone bristles, i.e., a two-in-one brush head. The bristle carrier 24 is connected to one end of the brush handle 1. Compared with the disposable cotton / sponge brush head, the brush head 2 in this embodiment has a better cleaning effect.
[0063] The brush handle 1 is provided with a connecting part 13 for detachable connection with the brush head 2. The cleaning brush also includes another brush head (not shown in the figure) detachably connected to the connecting part 13. The other brush head can rotate in any direction relative to the brush handle 1. That is, in this embodiment, the brush handle 1 can not only connect to the brush head 2 which cannot rotate in its circumference, but also connect to the brush head which can rotate in any direction. This allows the user to choose according to their needs. If a better cleaning effect is required in the circumference of the brush handle 1, the brush head 2 which cannot rotate in the circumference of the brush handle 1 can be selected. If it is for daily cleaning and the cleaning effect in the circumference of the brush handle 1 is not required, the brush head which can rotate in any direction can be selected.
[0064] In some embodiments of this utility model, reference is made to Figure 7 The cleaning brush also includes a brush holder 4, which has a storage cavity 41 for storing the brush head 2 and a storage cavity 41 for storing another brush head. This facilitates the storage of the two brush heads and the placement of the entire cleaning brush.
[0065] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
