Description

Technical Field

[0001] This utility model relates to the field of cleaning tools, and in particular to a cleaning brush. Background Technology

[0002] Cleaning brushes are widely used in homes, industries, and other fields as everyday cleaning tools.

[0003] In related technologies, the structure of a cleaning brush mainly includes a handle and a brush head. The handle and the brush head are usually fixedly connected, and the user can control the brush head to effectively clean the appliance by holding the handle.

[0004] However, cleaning brushes with a fixed connection between the handle and the brush head are difficult to adapt flexibly to cleaning at different angles and positions, affecting cleaning efficiency and resulting in a poor user experience. Utility Model Content

[0005] This utility model provides a cleaning brush to solve the problem in related technologies where the handle and brush head are fixedly connected, making it difficult to flexibly adapt to cleaning at different angles and positions, thus affecting cleaning efficiency and resulting in a poor user experience.

[0006] This utility model provides a cleaning brush, including a brush handle and a brush head. The brush handle and the brush head are rotatably connected by a rotating connection structure. The rotating connection structure includes a connecting hole, a snap-fit ​​part, and a plurality of connecting claws. The connecting hole and the snap-fit ​​part are located on the same part of the brush head and the brush handle, and the plurality of connecting claws are located on the other part of the brush head and the brush handle. The plurality of connecting claws can be brought together and inserted into the connecting hole, and after being inserted into the connecting hole, the plurality of connecting claws can be dispersed and locked around the periphery of the connecting hole.

[0007] The connecting claws are provided with gaps at both ends of the connecting hole and the adjacent connecting claws. The relative rotation of the brush handle and the brush head can drive the locking part to switch between at least two of the gaps. The locking part can be locked into any one of the at least two gaps to restrict the relative rotation of the brush head and the brush handle.

[0008] In the cleaning brush provided by this utility model, the brush handle and brush head are rotatably connected through a rotating connection structure. Specifically, one of the brush head and brush handle is provided with a connecting hole and a locking part, while the other is provided with multiple connecting claws. After the multiple connecting claws come together, they can extend into the connecting hole. After extending into the hole, the multiple connecting claws disperse and lock around the periphery of the connecting hole to achieve the connection between the brush handle and the brush head. In addition, there are gaps between the two ends of the connecting claws along the circumference of the connecting hole and the adjacent connecting claws. The relative rotation between the brush handle and the brush head can drive the locking part to switch between at least two gaps. When the locking part is locked into any gap, the relative rotation between the brush head and the brush handle can be restricted. At this time, the brush handle and the brush head are locked at a certain angle. Users can use it to clean at specific angles and positions, which improves cleaning efficiency and effect and enhances user experience.

[0009] According to the present invention, a cleaning brush is provided in which the engaging portion engages with the gap from the periphery of the plurality of connecting claws toward the area enclosed by the plurality of connecting claws; and / or, the engaging portion engages with the gap from the free end of the connecting claw toward the root of the connecting claw.

[0010] This embodiment provides a specific implementation method for the locking part to engage with the gap. Specifically, the locking part can engage with the gap between multiple connecting claws from the outer periphery of the connecting claws toward the area enclosed by the connecting claws, and / or the locking part can also engage with the gap between multiple connecting claws from the free end of the connecting claws toward the root of the connecting claws. Both of these methods of engaging the locking part with the gap are convenient for user operation, so as to lock the angle between the brush handle and the brush head for cleaning.

[0011] According to the present invention, a cleaning brush is provided with a snap-fit ​​part disposed on the inner wall of the connecting hole, and snaps into the gap from the periphery of the plurality of connecting claws toward the area enclosed by the plurality of connecting claws.

[0012] This embodiment provides a specific implementation of the locking part's location. Specifically, the locking part is located on the inner wall of the connecting hole. After multiple connecting claws converge and extend into the connecting hole, the claws disperse and lock onto the locking part around the periphery of the connecting hole. By relatively rotating the brush handle and brush head, the user can cause the locking part to engage in the gap from the periphery of the connecting claws towards the area enclosed by the claws, thereby locking the angle between the brush handle and brush head for cleaning.

[0013] According to the present invention, the bearing portion of the snap-fit ​​part is elastic, and the bearing portion can deform when the brush handle and the brush head rotate relative to each other, so that the snap-fit ​​part can disengage from the gap in which it is located, and the deformation can be restored when the snap-fit ​​part is opposite to another gap, so that the snap-fit ​​part can be engaged in the other gap.

[0014] This embodiment provides a specific implementation of the locking part. Specifically, the bearing portion of the locking part is elastic. When the user needs to adjust the relative angle between the brush handle and the brush head, they can rotate the brush handle and brush head relative to each other. At this time, the bearing portion of the locking part deforms and disengages from the gap until the locking part aligns with another gap, at which point the deformation returns to its original position, locking into that gap and locking the brush handle and brush head at other angles. By making the bearing portion of the locking part elastic, the user can easily unlock the brush handle and brush head at a certain angle by rotating them relative to each other, and then lock the brush handle and brush head in place by engaging the locking part into the gap.

[0015] According to the present invention, when the snap-fit ​​part is provided on the inner wall of the connecting hole, the bearing part is provided with a deformation space on the side away from the center of the connecting hole, so that the bearing part can deform away from the center of the connecting hole when the brush handle and the brush head rotate relative to each other, thereby facilitating the snap-fit ​​part to disengage from the gap.

[0016] This embodiment provides another specific implementation of the snap-fit ​​part. Specifically, when the snap-fit ​​part is located on the inner wall of the connecting hole, a deformation space is provided on the side of the bearing part away from the center of the connecting hole. When the user rotates the brush handle and brush head relative to each other, the bearing part can be squeezed and deformed within the deformation space, allowing the snap-fit ​​part to disengage from the gap. This avoids the connection between the brush handle and brush head being affected by the deformation of the bearing part, improving the stability of the connection between the brush handle and brush head during angle adjustment. Furthermore, it prevents the deformation of the bearing part from squeezing the connecting hole, which could cause deformation or even damage to the brush head, thus extending the service life of the brush head to a certain extent.

[0017] According to the present invention, a cleaning brush is provided, wherein the deformation space is an arc-shaped groove, and the center of the arc-shaped groove coincides with the center of the connecting hole.

[0018] This embodiment provides a specific implementation of the deformation space. The deformation space is designed as an arc-shaped groove, with the center of the groove coinciding with the center of the connecting hole. This allows the deformation space to effectively buffer the deformation of the bearing portion of the locking part during relative rotation of the brush handle and brush head, thus mitigating the squeezing effect on the connecting hole. This improves the stability of the connection between the brush handle and brush head during brush head angle adjustment and, to some extent, extends the service life of the brush head.

[0019] According to the present invention, a cleaning brush is provided, wherein the brush head includes a brush head body and a brushing part connected to the brush head body, the brush head body and the brush handle are rotatably connected by the rotating connection structure, and the brush handle or the brush head body is further provided with a head removal structure, the head removal structure being used to drive the brushing part to detach from the brush head body.

[0020] This embodiment provides a specific implementation of the brush head. The brush head includes a brush head body and a cleaning section connected to the brush head body. The brush head body is rotatably connected to the brush handle via a rotating connection structure, and the cleaning section is used for cleaning. Furthermore, the brush handle or brush head body is equipped with a detachable mechanism, allowing the user to use this mechanism to detach the cleaning section from the brush head body, thus facilitating the replacement or adjustment of the cleaning section to other cleaning types without requiring manual disassembly, thereby improving the user experience.

[0021] According to the present invention, a cleaning brush is provided, wherein the head removal structure includes a sliding rod that passes through the brush handle, and one end of the sliding rod passes through the area surrounded by a plurality of connecting claws, thereby driving the brushing part to detach from the brush head body.

[0022] This embodiment provides a specific implementation of the head removal structure. The specific head removal structure includes a sliding rod inserted into the brush handle. The user can drive the sliding rod so that one end of the sliding rod passes through the area surrounded by multiple connecting claws and moves towards the brushing section, thereby causing the brushing section to detach from the brush head body. Because the sliding rod is located on the brush handle, it is closer to the user's hand, making it convenient for the user to use.

[0023] According to the present invention, a cleaning brush is provided on the brush handle, which is provided with a support plate for supporting a plurality of connecting claws. The support plate is provided with a through hole in the area surrounded by the plurality of connecting claws. One end of the sliding rod passes through the through hole and the area surrounded by the plurality of connecting claws, thereby driving the brushing part to detach from the brush head body.

[0024] This embodiment provides a specific implementation of the brush handle. The brush handle is provided with a support plate for supporting multiple connecting claws, facilitating the stable mounting of the connecting claws on the brush handle. The support plate has a through-hole in the area enclosed by the multiple connecting claws, allowing one end of a sliding rod to pass through this through-hole and the area enclosed by the multiple connecting claws and move towards the brushing section. This causes the brushing section to detach from the brush head body. Without affecting the rotational connection between the brush handle and the brush head, the sliding rod can assist in disassembling the brushing section, improving the user experience.

[0025] According to the present invention, a cleaning brush is provided on the brush handle at a position where it is rotatably connected to the brush head. The first mating surface is inclined relative to the extension direction of the brush handle. The brush head is provided with a second mating surface, which is in contact with the first mating surface.

[0026] This embodiment provides a specific implementation of the connection position between the brush handle and the brush head. Specifically, the brush handle has a first mating surface, and the brush head has a second mating surface. The brush handle and the brush head are connected via the first and second mating surfaces. When the brush handle and the brush head rotate relative to each other, the first and second mating surfaces also rotate relative to each other. Furthermore, the first mating surface is inclined relative to the extension direction of the brush handle, allowing the user to adjust the specific orientation of the brush head when rotating the brush handle and the brush head relative to each other. For example, the brush head can be adjusted to the desired cleaning angle to improve cleaning effect, or the brush head can be adjusted to an angle that allows for removal, thus facilitating user operation.

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0042] In the description of this utility model, it should be clarified that the terms "vertical", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "horizontal", etc., which indicate orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model. They do not mean that the device or element referred to must have a specific orientation or position, and therefore should not be construed as a limitation on this utility model.

[0043] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" 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 mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components; they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0045] The cleaning brush of this utility model is described below with reference to the accompanying drawings.

[0046] According to one aspect, this utility model provides a cleaning brush. Figure 1 This is one of the structural schematic diagrams of the cleaning brush provided by this utility model. Figure 2 This is the second structural schematic diagram of the cleaning brush provided by this utility model. Figure 2 This is an explosion diagram of a cleaning brush, such as... Figure 1 and Figure 2As shown, the cleaning brush includes a handle 10 and a brush head 20. The handle 10 and the brush head 20 are rotatably connected by a rotating connection structure 30. The rotating connection structure 30 includes a connection hole 301, a snap-fit ​​part 302, and a plurality of connecting claws 303. The connection hole 301 and the snap-fit ​​part 302 are located on the same part of the brush head 20 and the handle 10, and the plurality of connecting claws 303 are located on the other part of the brush head 20 and the handle 10. The plurality of connecting claws 303 can be brought together and inserted into the connection hole 301. After the plurality of connecting claws 303 are inserted into the connection hole 301, they can be dispersed and snapped around the periphery of the connection hole 301.

[0047] The connecting claw 303 has gaps A at both ends of the connecting hole 301 and the adjacent connecting claw 301. The relative rotation of the brush handle 10 and the brush head 20 can drive the locking part 302 to switch between at least two gaps A. The locking part 302 can lock into any one of the at least two gaps A to restrict the relative rotation of the brush head 20 and the brush handle 10.

[0048] It should be noted that the above Figure 1 and Figure 2 The example shown is only exemplified by having a connecting hole 301 and a snap-fit ​​part 302 on the brush head 20 and multiple connecting claws 303 on the brush handle 10. This application does not limit the scope of the example.

[0049] Specifically, users can hold the brush handle 10 and use the brush head 20 to clean objects. In related technologies, the brush handle and brush head are usually fixed together and cannot rotate relative to each other. That is, the orientation of the brush head relative to the brush handle is fixed. When users use such a cleaning brush, it is difficult to clean certain angles or dead corners, resulting in low cleaning efficiency and poor cleaning effect, and poor user experience.

[0050] To address the aforementioned issues, the cleaning brush provided in this application allows for a rotatable connection between the brush handle 10 and the brush head 20 via a rotatable connection structure 30. In this rotatable connection structure 30, a connecting hole 301 and a locking portion 302 are configured as a set on one of the brush head 20 and the brush handle 10, while the other is provided with multiple connecting claws 303. These connecting claws 303 can undergo elastic deformation. When the multiple connecting claws 303 converge, they can extend into the connecting hole 301. After the multiple connecting claws 303 are inserted into the connecting hole 301, their elastic deformation is restored, and the multiple connecting claws 303 disperse and lock onto the periphery of the connecting hole 301. At this time, the multiple connecting claws 303 and the periphery of the connecting hole 301 can rotate relative to each other.

[0051] In addition, each connecting claw 303 has a gap A between its two ends along the circumference of the connecting hole 301 and the adjacent connecting claw 303. Therefore, there are multiple gaps A along the circumference of the connecting hole 301, and each gap A can accommodate and engage with the locking part 302.

[0052] It should be noted that the angle between the brush handle 10 and the brush head 20 can be different when the engaging part 302 engages with different gaps A. Therefore, the user can rotate the brush handle 10 and the brush head 20 relative to each other to engage the engaging part 302 with one of the gaps A, thereby locking the brush handle 10 and the brush head 20 at a certain angle, which facilitates effective cleaning at different angles and positions.

[0053] Optionally, one or more locking parts 302 can be provided. When multiple locking parts are provided, it should be noted that the number of gaps A formed between multiple connecting claws 303 needs to be greater than the number of locking parts 302. When the brush handle 10 and the brush head 20 are locked to any angle, multiple locking parts 302 need to be locked into multiple gaps A at the same time to ensure the stability of the connection between the brush handle 10 and the brush head 20.

[0054] In the cleaning brush provided by this utility model, the brush handle 10 and the brush head 20 are rotatably connected by a rotatable connection structure 30. Specifically, one of the brush head 20 and the brush handle 10 is provided with a connecting hole 301 and a locking part 302, while the other is provided with multiple connecting claws 303. The multiple connecting claws 303 can be gathered together and inserted into the connecting hole 301. After being inserted, the multiple connecting claws 303 disperse and lock around the periphery of the connecting hole 301 to achieve the connection between the brush handle 10 and the brush head 20. In addition, the connecting claws 303... 03. Gap A is provided between both ends of the connecting hole 301 and the adjacent connecting claw 303. The relative rotation between the brush handle 10 and the brush head 20 can drive the locking part 302 to switch between at least two gaps A. When the locking part 302 is locked into any gap A, the relative rotation between the brush head 20 and the brush handle 10 can be restricted. At this time, the brush handle 10 and the brush head 20 are locked at a certain angle. Users can use it to clean at a specific angle and position, which improves cleaning efficiency and effect and enhances user experience.

[0055] In some embodiments, a specific implementation of the snap-fit ​​portion 302 snapping into the gap A is provided. Figure 3 This is the third structural schematic diagram of the cleaning brush provided by this utility model, as shown below. Figures 1 to 3 As shown, the locking part 302 is engaged in the gap A from the periphery of the plurality of connecting claws 303 toward the area enclosed by the plurality of connecting claws 303; and / or, the locking part 302 is engaged in the gap A from the free end of the connecting claw 303 toward the root of the connecting claw 303.

[0056] It should be noted that, as Figure 3 As indicated by the middle arrow, the direction in which the snap-fit ​​part 302 engages with the gap A can include at least:

[0057] 1) First direction B: The engaging part 302 engages with the gap A from the periphery of the multiple connecting claws 303 toward the area enclosed by the multiple connecting claws 303. This can be understood as the engaging part 302 wrapping around the periphery of the multiple connecting claws 303 and aligning with the gap A in the radial direction. Then, the engaging part 302 gradually penetrates into the gap A formed by the multiple connecting claws 303 from the side and engages with the gap A.

[0058] 2) Second direction C: The snap-fit ​​part 302 snaps into the gap A from the free end of the connecting claw 303 toward the root of the connecting claw 303. It can be understood that after the snap-fit ​​part 302 and the gap A formed by the multiple connecting claws 303 are aligned with each other axially upward, the snap-fit ​​part 302 gradually penetrates into the gap A formed by the multiple connecting claws 303 and snaps into the gap A.

[0059] Specifically, the locking part 302 can be engaged from the periphery of the connecting claw 303 toward the area enclosed by the connecting claw 303 into the gap A between the multiple connecting claws 303, and / or the locking part 302 can also be engaged from the free end of the connecting claw 303 toward the root of the connecting claw 303 into the gap A between the multiple connecting claws 303. Both of these ways of engaging the locking part 302 into the gap A are convenient for user operation, so as to lock the angle between the brush handle 10 and the brush head 20 for cleaning.

[0060] In some embodiments, a specific implementation of the positioning of the latching portion 302 is provided. For example... Figures 1 to 3 As shown, the snap-fit ​​part 302 is provided on the inner wall of the connection hole 301, and is snapped into the gap A from the periphery of the multiple connecting claws 303 toward the area enclosed by the multiple connecting claws 303.

[0061] Specifically, the locking part 302 is provided on the inner wall of the connecting hole 301. After the multiple connecting claws 303 converge and extend into the connecting hole 301, the multiple connecting claws 303 disperse and can be locked on the locking part 302 around the connecting hole 301. By rotating the brush handle 10 and the brush head 20 relative to each other, the user can make the locking part 302 lock into the gap A from the periphery of the multiple connecting claws 303 towards the area surrounded by the multiple connecting claws 303, that is, lock into the gap A in the first direction B mentioned above, so as to lock the angle between the brush handle 10 and the brush head 30 for cleaning.

[0062] For example, taking a snap-fit ​​part 302 as an example, when installing the brush handle 10 and the brush head 20, the user can first align the snap-fit ​​part 302 with a certain gap A, and then snap the snap-fit ​​part 302 directly into the gap A in the second direction C mentioned above, so as to lock the angle between the brush handle 10 and the brush head 30 for cleaning.

[0063] In some embodiments, a specific implementation of the latching part 302 is provided. Figure 4This is one of the structural schematic diagrams of the brush head in the cleaning brush provided by this utility model, such as... Figures 1 to 4 As shown, the bearing portion D of the snap-fit ​​portion 302 is elastic. The bearing portion D can deform when the brush handle 10 and the brush head 20 rotate relative to each other, so that the snap-fit ​​portion 302 can be disengaged from the gap A where it is located, and the deformation can be restored when the snap-fit ​​portion 302 is opposite to another gap A, so that the snap-fit ​​portion 302 can be snapped into another gap A.

[0064] It should be noted that the bearing portion D of the aforementioned snap-fit ​​portion 302 can be understood as the portion that snaps into the gap A and directly receives force from the edge of the gap A.

[0065] Specifically, the bearing portion D of the locking part 302 is elastic. When the user needs to adjust the relative angle between the brush handle 10 and the brush head 20, they can rotate the brush handle 10 and the brush head 20 relative to each other. At this time, the bearing portion D of the locking part 302 will deform and disengage from the gap A until the locking part 302 is aligned with another gap A. The deformation will then return to its original state, locking into the other gap A and locking the brush handle 10 and the brush head 20 at other angles. By making the bearing portion D of the locking part 302 elastic, the user can easily unlock the brush handle 10 and the brush head 20 at a certain angle by rotating them relative to each other, and then lock the brush handle 10 and the brush head 20 into the gap A by locking the locking part 302 into the gap A.

[0066] In some embodiments, another specific implementation of the latching portion 302 is provided. For example... Figures 1 to 4 As shown, when the snap-fit ​​part 302 is provided on the inner wall of the connecting hole 301, the bearing part D is provided with a deformation space E on the side away from the center of the connecting hole 301, so that the bearing part D can deform in the direction away from the center of the connecting hole 301 when the brush handle 10 and the brush head 20 rotate relative to each other, thereby facilitating the snap-fit ​​part 302 to disengage from the gap A.

[0067] Specifically, when the snap-fit ​​part 302 is located on the inner wall of the connecting hole 301, the bearing part D is also provided with a deformation space E on the side away from the center of the connecting hole 301. When the user rotates the brush handle 10 and the brush head 20 relative to each other, the bearing part D can be squeezed and deformed by the deformation space E, so that the snap-fit ​​part 302 can be dislodged from the gap A. At the same time, it avoids the connection between the brush handle 10 and the brush head 20 being affected by the deformation of the bearing part D, thereby improving the stability of the connection between the brush handle 10 and the brush head 20 during the angle adjustment process. It also avoids the deformation of the bearing part D from squeezing the connecting hole 301, which would cause the brush head 20 to deform or even be damaged, thus extending the service life of the brush head 20 to a certain extent.

[0068] In some embodiments, a specific implementation of the deformation space E is provided. For example... Figures 1 to 4As shown, the deformation space E is an arc-shaped groove, and the center of the arc-shaped groove coincides with the center of the connecting hole 301.

[0069] Specifically, the deformation space E is set as an arc-shaped groove, and the center of the arc-shaped groove coincides with the center of the connecting hole 301. This allows the deformation space E to effectively buffer the deformation of the bearing part D of the locking part 302 during relative rotation of the brush handle 10 and the brush head 20, thereby reducing the squeezing effect on the connecting hole 301. This improves the stability of the connection between the brush handle 10 and the brush head 20 during the brush head angle adjustment process and extends the service life of the brush head 20 to a certain extent.

[0070] Optionally, the aforementioned deformation space E can also be set as a groove of other shapes, and there is no limitation on the number and specific location of the deformation spaces E, as long as the deformation space E can buffer the squeezing effect of the deformation of the bearing part D on the connecting hole 301. This application does not impose any restrictions on this.

[0071] In some embodiments, a specific implementation of the brush head 20 is provided. Figure 5 This is the second schematic diagram of the structure of the brush head in the cleaning brush provided by this utility model. Figure 6 This is the fourth structural schematic diagram of the cleaning brush provided by this utility model, as shown below. Figures 1 to 6 As shown, the brush head 20 includes a brush head body 201 and a brushing part 202 connected to the brush head body 201. The brush head body 201 and the brush handle 10 are rotatably connected by a rotating connection structure 30. The brush handle 10 or the brush head body 201 is also provided with a head removal structure 40, which is used to drive the brushing part 202 to detach from the brush head body 201.

[0072] For example, a cleaning brush can be provided with various types of brushing parts 202, and different types of brushing parts 202 have different types of bristle portions, such as nylon bristles, metal wire bristles, mixed bristles, etc., to suit different types of cleaning scenarios.

[0073] Optionally, when the brush head 20 is in a preset orientation among multiple rotatable orientations, or when the brush head 20 is in any one of the multiple rotatable orientations, the head removal structure 40 can drive the brush washing part 202 to detach from the brush head body 201, making it convenient for the user to disassemble the brush washing part 202 through the head removal structure 40, so that the user can replace different brush washing parts 202 to suit different types of cleaning, effectively improving the cleaning effect and user experience.

[0074] Specifically, the brush head 20 includes a brush head body 201 and a brushing section 202 connected to the brush head body 201. The brush head body 201 is rotatably connected to the brush handle 10 via a rotating connection structure 30, and the brushing section 202 is used for cleaning. In addition, the brush handle 10 or the brush head body 201 is also provided with a head removal structure 40. Users can use the head removal structure 40 to detach the brushing section 202 from the brush head body 201 to assist in disassembling the brushing section 202. This makes it convenient for users to replace or adjust the brushing section 202 to other cleaning types without having to manually disassemble the brushing section 202 used for cleaning, thus improving the user experience.

[0075] For example, the head removal structure 40 can be provided on the brush handle 10. When the brush handle 10 and the brush head body 201 rotate relative to each other, the head removal structure 40 will rotate with the brush handle 10 relative to the brush head body 201, and drive the brush washing part 202 to detach from the brush head body 201, thereby realizing the disassembly of the brush washing part 202. Since the head removal structure 40 is provided on the brush handle 10, it is closer to the user's hand, thus making it convenient for the user to use.

[0076] For example, compared to placing the detachable head structure 40 on the brush handle 10, where the user is more likely to accidentally touch the detachable head structure 40 when holding the brush handle 10 for cleaning, this embodiment can place the detachable head structure 40 on the brush head body 201, which is relatively far from the user's hand and less likely to be accidentally touched.

[0077] In some embodiments, a specific implementation of the unloading structure 40 is provided. For example... Figures 1 to 6 As shown, the head removal structure 40 includes a sliding rod that passes through the brush handle 10. One end of the sliding rod passes through the area surrounded by multiple connecting claws 303, thereby causing the brushing part 202 to detach from the brush head body 201.

[0078] Specifically, the head removal structure 40 includes a sliding rod that passes through the brush handle 10. The user can drive the sliding rod so that one end of the sliding rod passes through the area surrounded by multiple connecting claws 303 and moves toward the brush washing part 202, thereby causing the brush washing part 202 to detach from the brush head body 201. Since the sliding rod is located on the brush handle 10, it is closer to the user's hand, thus making it convenient for the user to use.

[0079] Optionally, the aforementioned sliding rod can also be replaced with other non-rod-shaped objects, or configured as a rod-shaped object combined with other shaped objects to assist in unloading the head; this application does not impose any restrictions.

[0080] Optionally, the aforementioned head removal structure 40 may further include an operating unit, such as a button. The operating unit can be connected to a sliding rod for transmission. When the user drives the operating unit, it can move the sliding rod, thereby causing the brushing part 202 to detach from the brush head body 201. The operating unit can be positioned in a location convenient for the user to operate. The user can directly move the sliding rod through this convenient operating unit to disassemble the brushing part 202, thus improving the user experience.

[0081] In some embodiments, a specific implementation of the brush handle 10 is provided. Figure 7 This is a schematic diagram of the brush handle in the cleaning brush provided by this utility model, as shown below. Figures 1 to 7 As shown, the brush handle 10 is provided with a support plate 101 for supporting multiple connecting claws 303. The support plate 101 is provided with a through hole F in the area surrounded by the multiple connecting claws 303. One end of the sliding rod passes through the through hole F and the area surrounded by the multiple connecting claws 303, thereby driving the brushing part 202 to detach from the brush head body 201.

[0082] Specifically, the brush handle 10 is provided with a support plate 101 for supporting multiple connecting claws 303, which facilitates the stable placement of multiple connecting claws 303 on the brush handle 10. The support plate 101 has a through-hole F in the area surrounded by multiple connecting claws 303, which allows one end of the sliding rod to pass through the through-hole F and the area surrounded by multiple connecting claws 303 and move towards the brush washing part 202, thereby driving the brush washing part 202 to detach from the brush head body 201. Without affecting the rotational connection between the brush handle 10 and the brush head 20, the sliding rod can assist in the disassembly of the brush washing part 202, improving the user experience.

[0083] In some embodiments, a specific implementation of the connection position between the brush handle 10 and the brush head 20 is provided. For example... Figures 1 to 7 As shown, the brush handle 10 is provided with a first mating surface at the position where it is rotatably connected to the brush head 20. The first mating surface is inclined relative to the extension direction of the brush handle 10. The brush head 20 is provided with a second mating surface, which is in contact with the first mating surface.

[0084] Specifically, the brush handle 10 has a first mating surface, and the brush head 20 has a second mating surface. The brush handle 10 and the brush head 20 are mated together through the first and second mating surfaces. When the brush handle 10 and the brush head 20 rotate relative to each other, the first and second mating surfaces also rotate relative to each other. In addition, the first mating surface is inclined relative to the extension direction of the brush handle 10, so that when the brush handle 10 and the brush head 20 rotate relative to each other, the user can adjust the specific orientation of the brush head 20. For example, the orientation of the brush head 20 can be adjusted to the angle required for cleaning to improve the cleaning effect, or the orientation of the brush head 20 can be adjusted to the angle that allows for removal of the brush head 20, so as to facilitate the user's use.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
