[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Therefore, they should not be construed as limitations on this utility model.
[0034] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0036] Reference Figures 1 to 4 This utility model embodiment provides a cleaning brush, including: a first brush head 5, which includes a first brush head body 51, a first clamping member 52, and a connecting member 53 connecting the first brush head body 51 and the first clamping member 52. The first brush head 5 can be a sponge brush head, a cotton brush head, a bristle-embedded brush head, a silicone brush head, a bristle-embedded and silicone two-in-one brush head, etc., and this embodiment does not limit this; a brush handle 1, which is provided with multiple clamping members B. The multiple clamping members B can be brought together to clamp the first clamping member 52. 2. The first brush head 5 and the brush handle 1 are connected by being clamped in the clamping cavity C. The multiple clamping members B can be spread out to release the first clamped member 52 from the clamping cavity C, so that the first brush head 5 and the brush handle 1 are separated. An embedding groove 6 is provided between adjacent clamping members B and / or on the clamping members B. The embedding groove 6 is used to allow the connecting member 53 to be embedded when the first clamped member 52 is clamped in the clamping cavity C and the first brush head body 51 and the connecting member 53 are deflected, so that the first brush head body 51 is deflected to the side of the embedding groove 6 away from the clamping cavity C.
[0037] The cleaning brush provided in this embodiment includes a first brush head 5 and a brush handle 1. The first brush head 5 includes a first brush head body 51, a first clamping member 52, and a connecting member 53 connecting the first brush head body 51 and the first clamping member 52. The brush handle 1 is provided with a plurality of clamping members B. The plurality of clamping members B can be brought together to clamp the first clamping member 52 in the clamping cavity C, so that the first brush head 5 and the brush handle 1 are connected. The plurality of clamping members B can be released from the clamping cavity C, so that the first brush head 5 and the brush handle 1 are separated. Since there are embedding grooves 6 between adjacent clamping members B and / or on the clamping members B, the embedding grooves 6 are used for the first clamping member 52. When the first brush head body 51 and the connector 53 are deflected in the clamping cavity C, the connector 53 is inserted so that the first brush head body 51 deflects to the side of the insertion groove 6 away from the clamping cavity C. That is, the setting of the insertion groove 6 allows the connector 53 to be inserted when the first brush head body 51 and the connector 53 are deflected. Compared with the solution in the prior art where the connector 53 cannot be inserted, the present invention has less restriction on the connector 53, thereby making the deflection range of the connector 53 wider, and thus allowing the first brush head 5 to deflect to the side of the insertion groove 6 away from the clamping cavity C. The deflection range of the first brush head 5 is increased, which expands the cleaning range of the first brush head 5.
[0038] Multiple clamping members B have a minimum clamping position for clamping the first clamped member 52. When multiple clamping members B are in the minimum clamping position, they can no longer converge. In some embodiments of this utility model, when multiple clamping members B are in the minimum clamping position, the width of the embedding groove 6 is less than the width of the connector 53. At this time, when the first brush head body 51 and the connector 53 deflect, the connector 53 needs to forcefully enter the embedding groove 6. When the embedding groove 6 is on the clamping member B, the connector 53 is not easy to enter, and after entering, it is not easy to move out of the embedding groove 6, making it difficult for the first brush head 5 to reset. When the embedding groove 6 is between adjacent clamping members B, it will spread the multiple clamping members B apart, thereby reducing the clamping effect of the multiple clamping members B. In other embodiments of this utility model, when multiple clamping members B are in the minimum clamping position, the width of the embedding groove 6 is greater than or equal to the width of the connector 53. At this time, when the first brush head body 51 and the connector 53 deflect, the connector 53 can easily enter the embedding groove 6, thereby avoiding the above-mentioned problems.
[0039] Reference Figure 3 and Figure 4 Preferably, there are multiple embedding slots 6, which are evenly distributed around the clamping cavity C. Compared with the embodiment with only one embedding slot 6, this embodiment can increase the deflection amplitude of the first brush head 5 in multiple directions, thereby making the cleaning range of the first brush head 5 wider.
[0040] Multiple clamping members B have clamping positions for clamping the first clamped member 52. The multiple clamping members B located in the clamping positions are simultaneously located inside the brush handle 1, thereby preventing the multiple clamping members B from extending out of the brush handle 1 in the clamping state, thus making the structure of the cleaning brush more regular and simple.
[0041] Based on the above embodiment, a notch 7 is provided on the brush handle 1 at the position corresponding to the embedding groove 6. The connector 53 can be embedded in the embedding groove 6 and the corresponding notch 7 at the same time, so that the first brush head body 51 is deflected to the side of the brush handle 1.
[0042] The width of the notch 7 can be greater than, less than, or equal to the width of the embedding groove 6. Compared to the cases where it is greater than or less than the cases, the case where the width of the notch 7 is equal to the width of the embedding groove 6 can also make the structure of the cleaning brush more regular and the processing more convenient.
[0043] In some embodiments of this utility model, a recessed portion 8 is provided on the brush handle 1 at the position corresponding to the notch 7. The recessed portion 8 is connected to the notch 7. The recessed portion 8 can avoid the deflection of the first brush head body 51, ensuring that the first brush head body 51 can be deflected to the side of the embedding groove 6 away from the clamping cavity C.
[0044] Reference Figures 4 to 8The cleaning brush in this embodiment also includes a second brush head 2 and a limiting structure 3. The second brush head 2 includes a second clamping member 21. Multiple clamping members B can converge to clamp the second clamping member 21 in the clamping cavity C, so that the second brush head 2 and the brush handle 1 are connected. Multiple clamping members B can disperse to release the second clamping member 21 from the clamping cavity C, so that the second brush head 2 and the brush handle 1 are separated. The limiting structure 3 is used to restrict the second brush head 2 from rotating around the brush handle 1. It can be seen that the cleaning brush in this embodiment connects the first brush head 5 or the second brush head 2. The first brush head 5 has a larger deflection range and a wider cleaning range. The second brush head 2 cannot rotate relative to the brush handle 1 around the circumference, which can avoid the phenomenon of the second brush head 2 slipping relative to the brush handle 1 when subjected to a force around the brush handle 1. This makes the cleaning effect of the cleaning brush around the brush handle 1 better. The selection and use of the first brush head 5 and the second brush head 2 can make the cleaning brush more comprehensive and more competitive in the market.
[0045] In some embodiments of this utility model, the brush handle 1 includes an outer surface A with at least a portion of its cross-section being non-circular. The limiting structure 3 is disposed on the second brush head 2 and abuts against the non-circular outer surface A to restrict the second brush head 2 from rotating circumferentially along the brush handle 1.
[0046] In some other embodiments of this utility model, 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 (not shown in the figure) and the end face of the brush handle 1 near the second brush head 2 (see reference). Figure 4 The gap D between adjacent clamping members B and the end face of the second brush head 2 and adjacent to the clamping cavity C (refer to) Figure 4 The second limiting part 32 is provided on at least one of the clamping member B near the end face (not shown in the figure) of the second brush head 2, and on the end face (not shown in the figure) of the clamping member B near the second brush head 2. Figure 8 The first limiting part 31 and the second limiting part 32 cooperate to restrict the second brush head 2 from rotating circumferentially along the brush handle 1. The first limiting part 31 is provided on the outer side of the brush handle 1, on the end face of the brush handle 1 near the second brush head 2, in the gap D between the end faces of the adjacent clamping member B near the second brush head 2 and adjacent to the clamping cavity C, and on the end face of the clamping member B near the second brush head. All of these are provided on the outer surface of the brush handle 1, and not 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 the user to operate.
[0047] In some embodiments of this utility model, reference is made to Figure 4 and Figure 7There are multiple limiting structures 3. When the non-circular outer side A abuts against the multiple limiting structures 3 respectively, the angle of the brush handle 1 relative to the second brush head 2 along its own circumference is different. In this way, the other angles of the brush handle 1 relative to the second brush head 2 along its own circumference can also enable the brush handle 1 to cooperate with the limiting structure 3 on the second brush head 6, with less restriction on the angle of the brush handle 1, which can facilitate the connection between the brush handle 1 and the second brush head 6.
[0048] Reference Figure 7 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 second 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 second brush head 6.
[0049] Too many limiting grooves will increase the difficulty of production, so 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. It also facilitates the connection between the brush handle 1 and the second brush head 6.
[0050] 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 second 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 7 and Figure 8 The second 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.
[0051] To facilitate the brush handle 1 entering the two limiting slots, refer to... Figure 8 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 second brush head 6.
[0052] Reference Figure 6 and Figure 7The second brush head 2 is provided with a socket 22. When the second brush head 2 and the brush handle 1 are connected, 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 second brush head 2 will not swing, thus avoiding the problem of poor brushing effect caused by the swinging of the second brush head 2.
[0053] 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 7 and Figure 8 In 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.
[0054] The second brush head 2 can be a disposable cotton / sponge brush head, or it can include a bristle 25 carrier 24 and bristles 25 disposed on the bristle 25 carrier 24. The bristles 25 here 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 second clamping member 21 is disposed on the bristle carrier 24. Compared with the disposable cotton / sponge brush head, the brush head of this embodiment has a better cleaning effect.
[0055] In some embodiments of this utility model, reference is made to Figure 9 The cleaning brush also includes a brush base 4, which has a storage cavity 41 for storing the first brush head 5 and the second brush head 2. This facilitates the storage of the first brush head 5 and the second brush head 2, and also makes it easier to arrange the entire cleaning brush.
[0056] 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.
