Abstract
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 fixed together, and the user can operate the brush head for effective cleaning by holding the handle.
[0004] However, the handles and brush heads of these technologies are usually fixed and non-removable, making it difficult for users to effectively adjust the orientation of the brush head or replace it with different brush heads to suit different types of cleaning, resulting in a poor user experience. Utility Model Content
[0005] This utility model provides a cleaning brush to solve the problem that the handle and brush head of related technologies are usually fixed and non-removable, making it difficult for users to effectively adjust the orientation of the brush head or replace it with different brush heads to suit different types of cleaning, resulting in a poor user experience.
[0006] This utility model provides a cleaning brush, comprising:
[0007] brush handle;
[0008] Brush head carrier;
[0009] Brush head;
[0010] Head-unloading structure;
[0011] The brush head is mounted on the brush head carrier, which is rotatably connected to the brush handle. The brush head carrier can rotate relative to the brush handle to switch the brush head between multiple orientations. When the brush head is in a preset orientation or any one of the multiple orientations, the brush head detachment structure can detach the brush head from the brush head carrier.
[0012] In the cleaning brush provided by this utility model, the brush head is mounted on a brush head carrier, which is rotatably connected to the brush handle. When using the brush, the user can hold the brush handle and rotate the brush head carrier relative to it, thereby switching the brush head between multiple orientations to adjust the angle between the brush head and the brush handle. This facilitates effective cleaning of objects at different positions and angles. Furthermore, by incorporating a detachable head structure, the user can detach the brush head from the brush head carrier when it is in a preset orientation or any other orientation. This allows for effective disassembly of the brush head even when it is rotatable between the brush head and the handle, making it easy for the user to adjust the brush head's orientation or replace it with different brush heads for different cleaning needs, effectively improving cleaning performance and user experience.
[0013] According to the present invention, a cleaning brush is provided with a first connecting part on the brush head and a second connecting part on the brush head carrier. The first connecting part is connected to the second connecting part. The detachment structure includes a pushing member movably disposed on the brush handle or the brush head carrier. When the brush head is located in a preset orientation or any one of the plurality of orientations, the pushing member is opposite to the first connecting part or the second connecting part to push the first connecting part or the second connecting part and thereby cause the brush head to detach from the brush head carrier.
[0014] This embodiment provides a specific connection structure between the brush head and the brush head carrier, and a specific implementation method for disassembling the brush head using a disassembly structure. Specifically, the brush head and the brush head carrier are connected by a first connecting part on the brush head and a second connecting part on the brush head carrier. The disassembly structure includes a pusher movably disposed on the brush handle or the brush head carrier. In actual use, when the brush head is in a preset orientation or any orientation among multiple orientations, the pusher will be opposite to the first or second connecting part. At this time, the user can drive the pusher to push the first or second connecting part, so that the brush head can be detached from the brush head carrier, thus achieving disassembly of the brush head. The disassembly principle is simple and easy to operate, making it convenient for users.
[0015] According to the present invention, a cleaning brush is provided, wherein the pushing member is disposed on the brush handle, and when the brush handle rotates relative to the brush head carrier, the pushing member rotates relative to the brush head carrier. When the brush head is located in a preset orientation or any one of the plurality of orientations, the pushing member is opposite to the first connecting part or the second connecting part to push the first connecting part or the second connecting part and thereby cause the brush head to detach from the brush head carrier.
[0016] This embodiment provides a specific implementation of the positioning of the pusher in the cleaning brush. Specifically, the pusher is located on the brush handle. When the brush handle rotates relative to the brush head carrier, the pusher rotates with the brush handle relative to the brush head carrier. However, when the brush head is in a preset orientation or any orientation among multiple orientations, the pusher will be opposite to the first connecting part or the second connecting part. At this time, the user can drive the pusher on the brush handle to push the first connecting part or the second connecting part, thereby detaching the brush head from the brush head carrier and achieving brush head disassembly. Since the pusher is located on the brush handle, it is closer to the user's hand, making it convenient for the user to use.
[0017] According to the present invention, a cleaning brush is provided, wherein the pushing member is a push rod, which is inserted into the brush handle. When the brush head is located in a preset orientation or any one of the plurality of orientations, one end of the push rod is opposite to the first connecting part or the second connecting part. The push rod can move toward the first connecting part or the second connecting part to push the first connecting part or the second connecting part, thereby causing the brush head to detach from the brush head carrier.
[0018] This embodiment provides a specific implementation of the pushing component. Specifically, the pushing component is a push rod inserted into the brush handle. When the brush head is in a preset orientation or any orientation among multiple orientations, one end of the push rod will be opposite to the first connecting part or the second connecting part. The user can drive the push rod to move it towards the first connecting part or the second connecting part until it pushes the first connecting part or the second connecting part, causing the brush head to detach from the brush head carrier. By setting a push rod to achieve detachable brush head, and by inserting the push rod into the original cleaning brush handle, it avoids the need to occupy a large space inside the cleaning brush due to the requirement of an additional pushing component, or even to increase the size of the cleaning brush to accommodate the pushing component. This effectively saves space inside the cleaning brush and facilitates flexible adjustment of the cleaning brush size to adapt to different cleaning types.
[0019] According to the present invention, a cleaning brush includes at least two preset orientations among the plurality of orientations. When the brush head is located in any orientation that allows the unloading structure to detach the brush head from the brush head carrier, the distance between the pushing end of the pushing member and the first connecting part is equal, so as to push the first connecting part and thereby detach the brush head from the brush head carrier.
[0020] This embodiment provides a specific implementation method for setting the relative positional relationship between the pusher and the first connecting part. Specifically, this application sets that when the brush head is in any preset orientation that allows the unloading structure to detach the brush head from the brush head carrier, the distance between the pusher end of the pusher and the first connecting part is equal. In this way, after the user drives the pusher to move the same distance, no matter which preset orientation the brush head rotates to, the pusher can push the brush head to detach from the brush head carrier, ensuring that the brush head can be effectively disassembled when it is in any preset orientation.
[0021] According to the present invention, a cleaning brush is provided on the first connecting part, and the rotation axis of the brush head carrier and the brush handle passes through the center of the partial spherical surface, so that when the brush head is in any orientation that allows the unloading structure to detach the brush head from the brush head carrier, the distance between the pushing end of the pushing member and the partial spherical surface is equal.
[0022] This embodiment provides a specific implementation of the first connecting part. Specifically, the first connecting part is provided with a partial spherical surface. The rotation axis of the brush head carrier and the brush handle passes through the center of the partial spherical surface. This ensures that when the brush head is in any orientation that allows the unloading structure to detach the brush head from the brush head carrier, the direction of the unloading structure on the brush handle is always directed towards the partial spherical surface. Furthermore, the distance between the pushing end of the pushing member and the partial spherical surface is always equal, guaranteeing that the brush head can be effectively disassembled when it is in any orientation that allows the unloading structure to detach the brush head from the brush head carrier. In addition, the partial spherical surface on the first connecting part allows the pushing member to be stably pushed towards the partial spherical surface and abut against it after being driven to do so, until the brush head detaches from the brush head carrier, preventing slippage and further ensuring the effective disassembly of the brush head.
[0023] According to the present invention, a cleaning brush is provided, wherein the second connecting part is a mounting hole, the first connecting part extends into the brush head carrier body through the mounting hole, the radial dimension of the first connecting part is greater than the radial dimension of the mounting hole, and when the pushing member pushes the first connecting part, the periphery of the first connecting part and / or the mounting hole may deform, so that the radial dimension of the first connecting part is smaller than the radial dimension of the mounting hole, so that the first connecting part can be dislodged from the mounting hole.
[0024] This embodiment provides a specific implementation method for connecting and disassembling the brush head and the brush head carrier. Specifically, the second connecting part is configured as a mounting hole, through which the first connecting part can extend into the brush head carrier. Since the radial dimension of the first connecting part is larger than the radial dimension of the mounting hole, the brush head cannot detach from the brush head carrier without external force after the first connecting part extends into the brush head carrier. When the user needs to disassemble the brush head, the pusher of the disassembly structure can be driven to push the first connecting part, causing deformation of the periphery of the first connecting part and / or the mounting hole, thereby making the radial dimension of the first connecting part smaller than the radial dimension of the mounting hole. This allows the first connecting part to be smoothly disassembled from the mounting hole, achieving the detachability of the brush head. The connection structure provided in this embodiment can effectively fix the brush head to the brush head carrier when not disassembled, and the disassembly method of the brush head is simple and easy to operate, facilitating user operation.
[0025] According to the present invention, a cleaning brush is provided in which the first connecting part is made of an elastic material. When the pusher pushes the first connecting part, the first connecting part is squeezed by the periphery of the mounting hole, causing its radial dimension to shrink until it is smaller than the radial dimension of the mounting hole, so that the first connecting part can be dislodged from the mounting hole.
[0026] And / or,
[0027] The periphery of the mounting hole is made of an elastic material. When the pusher pushes the first connecting part, the periphery of the mounting hole is expanded by the first connecting part until the radial dimension of the mounting hole is greater than the radial dimension of the first connecting part, so that the first connecting part can be dislodged from the mounting hole.
[0028] This embodiment provides a specific implementation method for deformation during disassembly of the first connecting part and the mounting hole. Specifically, the first connecting part can be made of an elastic material. When the pushing member pushes the first connecting part, the first connecting part is compressed by the periphery of the mounting hole, causing its radial dimension to shrink until it is smaller than the radial dimension of the mounting hole, at which point the first connecting part can be dislodged from the mounting hole. Alternatively, the periphery of the mounting hole can also be made of an elastic material. When the pushing member pushes the first connecting part, the periphery of the mounting hole is expanded by the first connecting part until the mounting hole is expanded to a radial dimension greater than the radial dimension of the first connecting part, at which point the first connecting part can be dislodged from the mounting hole. This application, by setting the first connecting part and / or the mounting hole to be made of an elastic material and using a pushing rod to push the first connecting part, causes deformation of the first connecting part and / or the mounting hole, thereby making the radial dimension of the first connecting part smaller than the radial dimension of the mounting hole, allowing the brush head to be disassembled. The connection and disassembly methods are simple and easy to operate, facilitating user operation.
[0029] According to the present invention, a cleaning brush is provided in which the second connecting part includes a plurality of clamping members, the plurality of clamping members can be brought together to clamp the first connecting part, and when the pushing member pushes the first connecting part, the first connecting part can be disengaged from the plurality of clamping members.
[0030] This embodiment provides another specific implementation method for connecting and disassembling the brush head and the brush head carrier. Specifically, the second connecting part includes multiple clamping members. When the first connecting part extends into the multiple clamping members, the multiple clamping members converge to clamp the first connecting part, realizing the connection between the brush head and the brush head carrier. When it is necessary to disassemble the brush head, the user can drive the pushing member to push the first connecting part, thereby causing the first connecting part to disengage from the multiple clamping members, so as to disassemble the brush head. The connection and disassembly method provided by this embodiment is simple and easy to operate, and convenient for users.
[0031] According to the present invention, a cleaning brush is provided with an annular groove along its circumference on the first connecting part. A plurality of clamping members are embedded in the annular groove to clamp the first connecting part. When the pushing member pushes the first connecting part, the first connecting part can drive the plurality of clamping members to disperse, so as to disengage from the plurality of clamping members.
[0032] This embodiment provides a specific implementation of the connection structure between the first connecting part and the clamping members. Specifically, the first connecting part has an annular groove along its circumference. After the first connecting part is inserted into multiple clamping members, the multiple clamping members will embed into the annular groove and clamp the first connecting part to firmly connect the brush head and the brush head carrier together. When it is necessary to disassemble the brush head, the user drives the pusher to push the first connecting part. At this time, the first connecting part is driven and can cause the multiple clamping members to disperse, so that the multiple clamping members can be disengaged from the annular groove of the first connecting part, thereby allowing the first connecting part to be disassembled from the multiple clamping members, realizing the detachable brush head. This connection and disassembly method is simple and easy to operate, and the connecting part is not easily damaged, which extends the service life of the cleaning brush to a certain extent.
[0033] According to the present invention, a cleaning brush is provided, wherein the clamping member is connected to a first elastic member. When the first connecting part causes the plurality of clamping members to disperse, the clamping member causes the first elastic member to undergo elastic deformation. After the first connecting part disengages from the plurality of clamping members, the elastic deformation of the first elastic member recovers and causes the plurality of clamping members to converge.
[0034] This embodiment provides a specific implementation of clamping the first connecting part with a clamping member. Specifically, each of the aforementioned clamping members is connected to a first elastic member. When the first connecting part drives the multiple clamping members to move in a dispersive direction, the clamping member causes the first elastic member to undergo elastic deformation. After the first connecting part disengages from the multiple clamping members, the elastic deformation of the first elastic member recovers, causing the multiple clamping members to converge, facilitating the next clamping of the brush head. By setting this first elastic member, this application allows the first connecting part to extend into and out of the clamping members. Furthermore, after the first connecting part extends into the multiple clamping members, the elastic force of the first elastic member compresses the clamping members to converge, making it less likely for the brush head to fall out of the clamping members when the user uses the cleaning brush. This improves the stability of the cleaning brush operation. Additionally, during the process of the first connecting part being pushed out by the pusher, the compression of the first elastic member reduces friction between the first connecting part and the multiple clamping members, making them less prone to damage and extending the service life of the cleaning brush to a certain extent.
[0035] According to the present invention, a cleaning brush is provided, wherein the head removal structure further includes an operating component, which is connected to the pushing component. The operating component can drive the pushing component to move, thereby pushing the first connecting part or the second connecting part and causing the brush head to detach from the brush head carrier.
[0036] And / or,
[0037] The unloading structure also includes a second elastic element, which is connected to the pusher. When the pusher pushes the first connecting part or the second connecting part to detach the brush head from the brush head carrier, it can cause the second elastic element to undergo elastic deformation. After the brush head is detached from the brush head carrier, the elastic deformation of the second elastic element recovers, which can cause the pusher to reset.
[0038] This embodiment provides a specific implementation of the brush head detachment structure. The detachment structure may further include an operating component connected to a pushing component. The operating component can be positioned for easy user operation, allowing the user to directly drive the pushing component to move, thereby pushing the first or second connecting part and detaching the brush head from the brush head carrier, achieving brush head detachability and effectively improving the user experience. Furthermore, the detachment structure may also include a second elastic component connected to the pushing component. When the user drives the pushing component to detach the brush head from the brush head carrier, the second elastic component undergoes elastic deformation. After the brush head detaches, the user can stop driving the pushing component, and the elastic deformation of the second elastic component will restore the pushing component to its original position, facilitating the user's next brush head detachment.
[0039] According to the present invention, a cleaning brush is provided on the brush handle at a position rotatably connected to the brush head carrier. The first mating surface is inclined relative to the extension direction of the brush handle. The brush head carrier is provided with a second mating surface, which is in contact with the first mating surface.
[0040] This embodiment provides a specific implementation of a rotatable connection between the brush handle and the brush head carrier. Specifically, the brush handle has a first mating surface, and the brush head carrier has a second mating surface. The brush handle and the brush head carrier are mated through the first and second mating surfaces. When the brush handle and the brush head carrier 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 carrier 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 a preset angle or other angle that allows for brush head removal, thus facilitating user operation.

[0056] 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.
[0057] 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.

[0058] 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.
[0059] 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.
[0060] The cleaning brush of this utility model is described below with reference to the accompanying drawings.
[0061] 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 2 As shown, the cleaning brush includes:
[0062] 10 brush handles;
[0063] Brush head carrier 20;
[0064] Brush head 30;
[0065] Unloading structure 40;
[0066] The brush head 30 is mounted on the brush head carrier 20, which is rotatably connected to the brush handle 10. The brush head carrier 20 can rotate relative to the brush handle 10 to switch the brush head 30 between multiple orientations. When the brush head 30 is in a preset orientation or any orientation among the multiple orientations, the brush head removal structure 40 can detach the brush head 30 from the brush head carrier 20.
[0067] It should be noted that the cleaning brushes in this embodiment include, but are not limited to, cleaning brushes for various purposes such as pot brushes and bathroom brushes, and this application does not impose any limitations on them.
[0068] Specifically, users can hold the brush handle 10 to clean different objects using the brush head 30. The brush head 30 is equipped with bristles, which are mainly used to clean objects. The brush head carrier 20 supports the brush head 30 and is connected to the brush handle 10. The brush head carrier 20 and the brush handle 10 can rotate. When the brush head carrier 20 rotates relative to the brush handle 10, the brush head 30 also rotates with the brush head carrier 20 relative to the brush handle 10, allowing the brush head 30 to switch between multiple orientations.
[0069] When the brush head 30 is in a preset orientation among multiple orientations, or when the brush head 30 is in any one of multiple orientations, the detachment structure 40 can detach the brush head 30 from the brush head carrier 20, making it convenient for the user to disassemble the brush head 30 through the detachment structure 40.
[0070] Optionally, the preset orientation can be one or at least two of a plurality of orientations.
[0071] For example, for cleaning brushes, multiple types of brush heads 30 can be provided, with different types of brush heads 30 having different types of bristle parts, such as nylon bristles, metal wire bristles, mixed bristles, etc., to suit different types of cleaning scenarios.
[0072] In the cleaning brush provided by this utility model, the brush head 30 is disposed on the brush head carrier 20, and the brush head carrier 20 is rotatably connected to the brush handle 10. When using the brush, the user can hold the brush handle 10 and rotate the brush head carrier 20 relative to it, thereby driving the brush head 30 to switch between multiple orientations to adjust the angle A between the brush head 30 and the brush handle 10. This makes it convenient for the user to use the cleaning brush to effectively clean objects at different positions and angles. In addition, by setting a head removal structure 40 in the cleaning brush, the user can use the head removal structure 40 to detach the brush head 30 from the brush head carrier 20 when the brush head 30 is in a preset orientation or any orientation among multiple orientations. This allows the brush head 30 to be effectively disassembled even when it can rotate between the brush head 30 and the brush handle 10. This makes it convenient for the user to adjust the orientation of the brush head 30 or replace it with a different brush head 30 to suit different types of cleaning, effectively improving the cleaning effect and user experience.
[0073] In some embodiments, a specific connection structure between the brush head 30 and the brush head carrier 20 is provided, and a specific implementation of how to disassemble the brush head 30 using the disassembly structure 40 is provided. Figure 3 This is a schematic diagram of the brush head structure in the cleaning brush provided by this utility model. Figure 4 This is one of the structural schematic diagrams of the brush head carrier in the cleaning brush provided by this utility model. Figure 5 This is the third structural schematic diagram of the cleaning brush provided by this utility model, as shown below. Figures 1 to 5 As shown, the brush head 30 is provided with a first connecting part 301, and the brush head carrier 20 is provided with a second connecting part 201. The first connecting part 301 is connected to the second connecting part 201. The unloading structure 40 includes a pusher 401 movably disposed on the brush handle 10 or the brush head carrier 20. When the brush head 30 is in a preset orientation or any orientation among multiple orientations, the pusher 401 is opposite to the first connecting part 301 or the second connecting part 201 to push the first connecting part 301 or the second connecting part 201 and thereby cause the brush head 30 to detach from the brush head carrier 20.
[0074] Specifically, the brush head 30 and the brush head carrier 20 are connected by a first connecting part 301 on the brush head 30 and a second connecting part 201 on the brush head carrier 20. The detachment structure 40 includes a pusher 401 movably disposed on the brush handle 10 or the brush head carrier 20. In actual use, when the brush head 30 is in a preset orientation or any orientation among multiple orientations, the pusher 401 will be opposite to the first connecting part 301 or the second connecting part 201. At this time, the user can drive the pusher 401 to push the first connecting part 301 or the second connecting part 201 so that the brush head 30 is detached from the brush head carrier 20, thereby realizing the disassembly of the brush head 30. The disassembly principle is simple and easy to operate, making it convenient for users.
[0075] In some embodiments, a specific implementation is provided for the specific positioning of the pusher 401 within the cleaning brush. For example... Figures 1 to 5 As shown, the pusher 401 is provided on the brush handle 10. When the brush handle 10 rotates relative to the brush head carrier 20, the pusher 401 rotates relative to the brush head carrier 20. When the brush head 30 is in a preset orientation or any orientation among multiple orientations, the pusher 401 is opposite to the first connecting part 301 or the second connecting part 201 to push the first connecting part 301 or the second connecting part 201 and thus cause the brush head 30 to detach from the brush head carrier 20.
[0076] Specifically, the pusher 401 is located on the brush handle 10. When the brush handle 10 rotates relative to the brush head carrier 20, the pusher 401 will rotate with the brush handle 10 relative to the brush head carrier 20. However, when the brush head 30 is in a preset orientation or any orientation among multiple orientations, the pusher 401 will be opposite to the first connecting part 301 or the second connecting part 201. At this time, the user can drive the pusher 401 on the brush handle 10 to push the first connecting part 301 or the second connecting part 201 so that the brush head 30 is detached from the brush head carrier 20, thereby disassembling the brush head 30. Since the pusher 401 is located on the brush handle 10, it is closer to the user's hand, thus making it convenient for the user to use.
[0077] Optionally, compared to placing the pusher 401 on the brush handle 10, where the user is more likely to accidentally touch the pusher 401 while holding the brush handle 10 for cleaning, this embodiment can place the pusher 401 on the brush head carrier 20. The brush head carrier 20 is relatively far from the user's hand, making it less likely to be accidentally touched. When the user needs to disassemble the brush head 30, they can drive the pusher 401 on the brush head carrier 20 to move towards the first connecting part 301 or the second connecting part 201, thereby pushing the first connecting part 301 or the second connecting part 201 to disassemble the brush head 30 from the brush head carrier 20.
[0078] Optionally, when the brush head 30 is in a preset orientation or any orientation among multiple orientations, the user can also pull the first connecting part 301 or the second connecting part 201 through the head removal structure 40 to move the first connecting part 301 or the second connecting part 201 in a direction away from each other until the brush head 30 is detached from the brush head carrier 20, or to twist the first connecting part 301 and the second connecting part 201 relative to each other until they are detached from each other.
[0079] In some embodiments, a specific implementation of the actuator 401 is provided. For example... Figures 1 to 5 As shown, the pusher 401 is a push rod that passes through the brush handle 10. When the brush head 30 is in a preset orientation or any orientation among multiple orientations, one end of the push rod is opposite to the first connecting part 301 or the second connecting part 201. The push rod can move toward the first connecting part 301 or the second connecting part 201 to push the first connecting part 301 or the second connecting part 201, thereby causing the brush head 30 to detach from the brush head carrier 20.
[0080] For example, the push rod passes through the brush handle 10 and is arranged along the extension direction of the brush handle 10. One end of the push rod also extends into the brush head carrier 20 to be opposite to the first connecting part 301 or the second connecting part 201.
[0081] Specifically, the pusher 401 is a push rod that passes through the brush handle 10. When the brush head 30 is in a preset orientation or any orientation among multiple orientations, one end of the push rod will be opposite to the first connecting part 301 or the second connecting part 201. The user can drive the push rod to move it toward the first connecting part 301 or the second connecting part 201 until the first connecting part 301 or the second connecting part 201 is pushed to detach the brush head 30 from the brush head carrier 20. Based on the fact that the push rod is set to make the brush head 30 detachable, the push rod passes through the original brush handle 10 of the cleaning brush. This can avoid the situation where a large space inside the cleaning brush is occupied due to the need to set an additional pusher 401, or even the need to increase the size of the cleaning brush to accommodate the pusher 401. This effectively saves space inside the cleaning brush and makes it easier to flexibly adjust the size of the cleaning brush to adapt to different cleaning types.
[0082] Optionally, the aforementioned pusher 401 can also be configured as other non-rod-shaped objects, or as a combination of rod-shaped objects and other shaped objects, as long as it can push the first connecting part 301 or the second connecting part 201 to detach the brush head 30 from the brush head carrier 20. This application does not impose any restrictions.
[0083] In some embodiments, a specific implementation method is provided for setting the relative positional relationship between the pusher 401 and the first connecting portion 301. For example... Figures 1 to 5As shown, the multiple orientations include at least two preset orientations. When the brush head 30 is in any orientation that allows the unloading structure 40 to detach the brush head 30 from the brush head carrier 20, the distance between the pushing end B of the pushing member 401 and the first connecting part 301 is equal, so as to push the first connecting part 301 and thereby detach the brush head 30 from the brush head carrier 20.
[0084] Specifically, this application sets that when the brush head 30 is in any preset orientation that allows the unloading structure 40 to detach the brush head 30 from the brush head carrier 20, the distance between the pushing end B of the pushing member 401 and the first connecting part 301 is equal. In this way, after the user drives the pushing member 401 to move the same distance, no matter which preset orientation the brush head 30 rotates to, the pushing member 401 can push the brush head 30 to detach from the brush head carrier 20, ensuring that the brush head 30 can be effectively disassembled when it is in any preset orientation.
[0085] In some embodiments, a specific implementation of the first connecting part 301 is provided. For example... Figures 1 to 5 As shown, the first connecting part 301 is provided with a partial spherical surface C. The rotation axis of the brush head carrier 20 and the brush handle 10 passes through the center of the partial spherical surface C, so that when the brush head 30 is in any orientation that allows the unloading structure 40 to drive the brush head 30 to detach from the brush head carrier 20, the distance between the pushing end B of the pushing member 401 and the partial spherical surface C is equal.
[0086] It should be noted that since the pusher 401 is inserted into the brush handle 10, the pusher 401 can be arranged to extend along the rotation axis of the brush head carrier 20 and the brush handle 10 toward the first connecting part 301. Since the rotation axis of the brush head carrier 20 and the brush handle 10 passes through the center of the local spherical surface C, one end of the pusher 401 will point toward the local spherical surface C and move toward the local spherical surface C when driven, until it abuts against the local spherical surface C and pushes the first connecting part 301, ultimately causing the brush head 30 to detach from the brush head carrier 20.
[0087] Specifically, the first connecting part 301 is provided with a partial spherical surface C. The rotation axis of the brush head carrier 20 and the brush handle 10 passes through the center of the partial spherical surface C. This ensures that when the brush head 30 is in any orientation that allows the unloading structure to detach the brush head from the brush head carrier, the direction of the unloading structure 40 on the brush handle 10 can always be directed towards the partial spherical surface C. Furthermore, the distance between the pushing end B of the pushing member 401 and the partial spherical surface C is always equal, ensuring that the brush head 30 can be effectively disassembled when it is in any orientation that allows the unloading structure to detach the brush head from the brush head carrier. In addition, the partial spherical surface C on the first connecting part 301 allows the pushing member 401 to be driven towards the partial spherical surface C and abut against it. This ensures that the first connecting part 301 can be stably pushed until the brush head 30 is detached from the brush head carrier 20, preventing slippage and further ensuring the disassembly effect of the brush head 30.
[0088] Optionally, the first connecting part 301 can also be configured as an aspherical surface. For example, the side of the first connecting part 301 opposite to the pusher 401 can be configured as a plane. After the pusher 401 is driven to move toward the plane and abuts against the plane, it can also stably push the first connecting part 301 until the brush head 30 is detached from the brush head carrier 20. It is not easy to slip and ensures the disassembly effect of the brush head 30.
[0089] It should be noted that the specific shape of the first connecting part 301 is not limited in the embodiments of this application, as long as it can be connected to the second connecting part 201 and can be disengaged from the second connecting part 201 under the push of the pusher 401.
[0090] Optionally, the pusher 401 can be directed at one end of the local spherical surface C, or it can be set as a plane or curved surface, so that when the pusher 401 is driven, it moves toward the local spherical surface C, and the set plane or curved surface can abut against the local spherical surface C and push the first connecting part 301, so that the brush head 30 is finally detached from the brush head carrier 20. The two surfaces abut against each other and transmit force, which can stably push the first connecting part 301 until the brush head 30 is detached from the brush head carrier 20, making it less prone to slippage and ensuring the disassembly effect of the brush head 30.
[0091] In some embodiments, a specific implementation method is provided for connecting and disassembling the brush head 30 and the brush head carrier 20. For example... Figures 1 to 5 As shown, the second connecting part 201 is a mounting hole D. The first connecting part 301 extends into the brush head carrier 20 through the mounting hole D. The radial dimension of the first connecting part 301 is larger than the radial dimension of the mounting hole D. When the pusher 401 pushes the first connecting part 301, the periphery of the first connecting part 301 and / or the mounting hole D can be deformed, so that the radial dimension of the first connecting part 301 is smaller than the radial dimension of the mounting hole D, so that the first connecting part 3001 can be dislodged from the mounting hole D.
[0092] For example, the first connecting part 301 and the mounting hole D can also be configured with other shapes, as long as the first connecting part 301 needs to be extended into or out of the mounting hole D with additional force, which is not limited in this application.
[0093] Specifically, the second connecting part 201 is configured as a mounting hole D. The first connecting part 301 can extend into the brush head carrier 20 through the mounting hole D. Since the radial dimension of the first connecting part 301 is larger than the radial dimension of the mounting hole D, the brush head 30 cannot detach from the brush head carrier 20 without external force after the first connecting part 301 extends into the brush head carrier 20. When the user needs to disassemble the brush head 30, the pusher 401 of the disassembly structure 40 can be driven to push the first connecting part 301, causing the periphery of the first connecting part 301 and / or the mounting hole D to deform, thereby making the radial dimension of the first connecting part 301 smaller than the radial dimension of the mounting hole D. This allows the first connecting part 301 to be smoothly disassembled from the mounting hole D, realizing the detachability of the brush head 30. The connecting structure provided in this embodiment can effectively fix the brush head 30 on the brush head carrier 20 when not disassembled, and the disassembly method of the brush head 30 is simple and easy to operate, making it convenient for users.
[0094] In some embodiments, a specific implementation is provided where the first connecting portion 301 deforms during disassembly from the mounting hole D. For example... Figures 1 to 5 As shown, the first connecting part 301 is made of elastic material. When the pusher 401 pushes the first connecting part 301, the first connecting part 301 is squeezed by the periphery of the mounting hole D, causing its radial dimension to shrink until it is smaller than the radial dimension of the mounting hole D, so that the first connecting part 301 can be dislodged from the mounting hole D.
[0095] And / or,
[0096] The periphery of the mounting hole D is made of an elastic material. When the pusher 401 pushes the first connecting part 301, the periphery of the mounting hole D is expanded by the first connecting part 301 until the radial dimension of the mounting hole D is greater than the radial dimension of the first connecting part 301, so that the first connecting part 301 can be dislodged from the mounting hole D.
[0097] Specifically, the first connecting part 301 can be made of an elastic material. When the pusher 401 pushes the first connecting part 301, the first connecting part 301 will be squeezed by the periphery of the mounting hole D, causing its radial dimension to shrink until it is smaller than the radial dimension of the mounting hole D, after which the first connecting part 301 can be dislodged from the mounting hole D. In addition, the periphery of the mounting hole D can also be made of an elastic material. When the pusher 401 pushes the first connecting part 301, the periphery of the mounting hole D will be expanded by the first connecting part 301 until the mounting hole D is expanded to a radial dimension greater than the radial dimension of the first connecting part 301, after which the first connecting part 301 can be dislodged from the mounting hole D. This application provides a first connecting part 301 and / or mounting hole D made of elastic material. By pushing the first connecting part 301 with a push rod 401, the first connecting part 301 and / or mounting hole D are deformed, so that the radial dimension of the first connecting part 301 is smaller than the radial dimension of the mounting hole D, the brush head 30 can be disassembled. The connection and disassembly method is simple and easy to operate, making it convenient for users.
[0098] For example, the periphery of the first connecting portion 301 and the mounting hole D can both be made of elastic material, as long as the first connecting portion 301 cannot extend into or out of the mounting hole D without additional force, and the first connecting portion 301 can be dislodged from the mounting hole D when additional force is applied by the pusher 401 to push the first connecting portion 301.
[0099] In some embodiments, another specific implementation method is provided for the connection and disassembly between the brush head 30 and the brush head carrier 20. Figure 6 This is the second structural schematic diagram of the brush head carrier in the cleaning brush provided by this utility model, as shown below. Figures 1 to 6 As shown, the second connecting part 201 includes a plurality of clamping members 2011. The plurality of clamping members 2011 can be gathered together to clamp the first connecting part 301. When the pushing member 401 pushes the first connecting part 301, the first connecting part 301 can be disengaged from the plurality of clamping members 2011.
[0100] Specifically, the second connecting portion 201 includes multiple clamping members 2011. When the first connecting portion 301 extends into the multiple clamping members 2011, the multiple clamping members 2011 converge to clamp the first connecting portion 301, thus connecting the brush head 30 to the brush head carrier 20. When it is necessary to disassemble the brush head 30, the user can drive the pushing member 401 to push the first connecting portion 301, thereby disengaging the first connecting portion 301 from the multiple clamping members 2011 to disassemble the brush head 30. This embodiment provides a simple and easy-to-operate connection and disassembly method for the connecting structure, making it convenient for users.
[0101] In other embodiments, such as Figure 6As shown, to ensure the firm connection between the brush head 30 and the brush head carrier 20, a mounting hole D and multiple clamping members 2011 can be provided on the brush head carrier 20. The multiple clamping members 2011 can be arranged around the mounting hole D. When installing the brush head 30, the first connecting part 301 can be forcefully inserted into the mounting hole D. After insertion, the radial dimension of the first connecting part 301 is larger than the radial dimension of the mounting hole D. At the same time, the multiple clamping members 2011 can clamp the first connecting part 301 inserted into the brush head carrier 20, so that the brush head 30 and the brush head carrier 20 are firmly connected. When disassembling the brush head 30, the pushing member 401 is driven to push the first connecting part 301 out of the mounting hole D and the multiple clamping members 2011 respectively, so that the brush head 30 is detached from the brush head carrier 20.
[0102] In some embodiments, a specific implementation of the connection structure between the first connecting portion 301 and the clamping member 2011 is provided. For example... Figures 1 to 6 As shown, the first connecting part 301 has an annular groove E along its circumference. Multiple clamping members 2011 are embedded in the annular groove E to clamp the first connecting part 301. When the pushing member 401 pushes the first connecting part 301, the first connecting part 301 can drive the multiple clamping members 2011 to disperse, so as to disengage from the multiple clamping members 2011.
[0103] Specifically, the first connecting part 301 has an annular groove E along its circumference. After the first connecting part 301 is inserted into the multiple clamping members 2011, the multiple clamping members 2011 will be embedded in the annular groove E around the circumference and clamp the first connecting part 301 to firmly connect the brush head 30 to the brush head carrier 20. When it is necessary to disassemble the brush head 30, the user drives the pusher 401 to push the first connecting part 301. At this time, the first connecting part 301 is driven and can cause the multiple clamping members 2011 to disperse, so that the multiple clamping members 2011 can be disengaged from the annular groove E of the first connecting part 301, thereby allowing the first connecting part 301 to be disengaged from the multiple clamping members 2011, realizing the disassembly of the brush head 30. This connection and disassembly method is simple and easy to operate, and the connecting part is not easily damaged, which extends the service life of the cleaning brush to a certain extent.
[0104] In some embodiments, a specific implementation of the clamping member clamping the first connecting portion is provided. For example... Figures 1 to 6 As shown, the clamping member 2011 is connected to the first elastic member. When the first connecting part 301 causes the multiple clamping members 2011 to disperse, the clamping member 2011 causes the first elastic member to undergo elastic deformation. After the first connecting part 301 disengages from the multiple clamping members 2011, the elastic deformation of the first elastic member recovers and causes the multiple clamping members 2011 to gather together.
[0105] For example, the first elastic element is, for example, a spring, such as Figure 6As shown, the first elastic element can be disposed on a fixing element disposed in the radial direction along the mounting hole D. The clamping element 2011 can move from the track on the fixing element toward or away from the mounting hole D. When multiple clamping elements 2011 move toward the mounting hole D, it is considered that the multiple clamping elements 2011 are gathered together; when multiple clamping elements 2011 move away from the mounting hole D, it is considered that the multiple clamping elements 2011 are dispersed. When the multiple clamping elements 2011 are dispersed, the first elastic element will be compressed and deformed.
[0106] Specifically, each of the aforementioned multiple clamping members 2011 is connected to a first elastic member. When the first connecting part 301 drives the multiple clamping members 2011 to move in a dispersing direction, the clamping member 2011 will cause the first elastic member to undergo elastic deformation. After the first connecting part 301 disengages from the multiple clamping members 2011, the elastic deformation of the first elastic member will restore and cause the multiple clamping members 2011 to gather together, making it easier to clamp the brush head 30 next time. By incorporating the first elastic element, this application enables the first connecting portion 301 to extend into and retract from the clamping member 2011. Simultaneously, after the first connecting portion 301 extends into multiple clamping members 2011, the elastic force of the first elastic element compresses the clamping members 2011, bringing them together. This prevents the brush head 30 from easily detaching from the clamping members 2011 during use, improving the stability of the cleaning brush. Furthermore, during the process of the first connecting portion 301 being pushed out by the pusher 401, the compression of the first elastic element reduces friction between the first connecting portion 301 and the multiple clamping members 2011, making them less prone to damage and extending the service life of the cleaning brush to a certain extent.
[0107] In some embodiments, a specific implementation of the head removal structure is provided. Figure 7 This is a schematic diagram of the head removal structure in the cleaning brush provided by this utility model, as shown below. Figures 1 to 7 As shown, the unloading structure 40 also includes an operating member 402, which is connected to the pushing member 401. The operating member 402 can drive the pushing member 401 to move, thereby pushing the first connecting part 301 or the second connecting part 201 to detach the brush head 30 from the brush head carrier 20.
[0108] And / or,
[0109] The unloading structure 40 also includes a second elastic element, which is connected to the pusher 401. When the pusher 401 pushes the first connecting part 301 or the second connecting part 201 to detach the brush head 30 from the brush head carrier 20, it can cause the second elastic element to undergo elastic deformation. After the brush head 30 is detached from the brush head carrier 20, the elastic deformation of the second elastic element recovers, which can cause the pusher 401 to reset.
[0110] For example, such as Figure 7 As shown, the operating element 402 is, for example, a button provided on the side wall of the brush handle 10. When the user needs to disassemble the brush head 30, he can press the button. The button is driven to move the pushing element 401 toward the first connecting part 301 or the second connecting part 201, and push the first connecting part 301 or the second connecting part 201 to make the brush head 30 detach from the brush head carrier 20.
[0111] Optionally, the button can also be located at the top of the brush handle 10, so that the direction of movement of the button is the same as the extension direction of the brush handle 10. This allows the user to drive the pusher 401 by pressing the button, thereby pushing the first connecting part 301 or the second connecting part 201 to detach the brush head 30 from the brush head carrier 20. This embodiment is only an example and does not limit the specific location of the button.
[0112] For example, such as Figure 7 As shown, the second elastic element is, for example, a spring F. The second elastic element can be sleeved on the outside of the pusher 401. The end of the second elastic element away from the brush head carrier 20 is connected to the non-pushing end of the pusher 401, and the end of the second elastic element near the brush head carrier 20 is connected to a mounting bracket provided inside the brush handle 10. This mounting bracket is used to mount the pusher 401 inside the brush handle 10. When the pusher 401 pushes the first connecting part 301 or the second connecting part 201 to disengage the brush head 30 from the brush head carrier 20, the second elastic element is compressed and undergoes elastic deformation. After the brush head 30 disengages from the brush head carrier 20, the user stops the driven pusher 401. At this time, the elastic deformation of the second elastic element recovers, which can drive the pusher 401 to reset.
[0113] Specifically, the brush head removal structure 40 may further include an operating member 402, which is connected to the pushing member 401. The operating member 402 can be positioned in a convenient location for user operation. The user can directly use the convenient operating member 402 to drive the pushing member 401 to push the first connecting part 301 or the second connecting part 201, thereby detaching the brush head 30 from the brush head carrier 20, making the brush head 30 detachable and effectively improving the user experience. In addition, the brush head removal structure 40 may further include a second elastic member, which is connected to the pushing member 401. When the user drives the pushing member 401 to push the first connecting part 301 or the second connecting part 201 to detach the brush head 30 from the brush head carrier 20, the second elastic member will undergo elastic deformation. After the brush head 30 is detached from the brush head carrier 20, the user can stop driving the pushing member 401. At this time, the elastic deformation of the second elastic member will restore the pushing member 401 to its original position, making it convenient for the user to remove the brush head 30 next time.
[0114] In some embodiments, a specific implementation is provided whereby the brush handle 10 and the brush head carrier 20 are rotatably connected. For example... Figures 1 to 7As shown, the brush handle 10 is provided with a first mating surface at the position where it is rotatably connected to the brush head carrier 20. The first mating surface is inclined relative to the extension direction of the brush handle 10. The brush head carrier 20 is provided with a second mating surface, which is in contact with the first mating surface.
[0115] Specifically, the brush handle 10 is provided with a first mating surface, and the brush head carrier 20 is provided with a second mating surface. The brush handle 10 and the brush head carrier 20 are mated together through the first and second mating surfaces. When the brush handle 10 and the brush head carrier 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 carrier 20 rotate relative to each other, the user can adjust the specific orientation of the brush head 30. For example, the orientation of the brush head 30 can be adjusted to the angle that needs to be cleaned to improve the cleaning effect, or the orientation of the brush head 30 can be adjusted to a preset angle or other angle that can be detached to achieve the disassembly of the brush head 30, which is convenient for the user.
[0116] For example, a connecting part can be provided on the second mating surface and the first mating surface, and the second mating surface and the first mating surface are connected through the connecting part. It should be noted that the connecting part needs to enable relative rotation between the second mating surface and the first mating surface to realize the rotational connection between the brush handle 10 and the brush head carrier 20.
[0117] 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.
