[0045] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments 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 protection scope of this utility model.

[0046] To address the issue of limited rotation angle of brush heads mounted on brush head mounts in related technologies, resulting in insufficient flexibility and applicability in complex cleaning scenarios, the following section combines... Figures 1 to 5 The following describes embodiments of the present invention.

[0047] According to an embodiment of the present invention, in one aspect, a cleaning brush is provided, such as... Figure 1 As shown, the cleaning brush includes a handle 1 and a brush head mounting base 2. The brush head mounting base 2 is used to detachably mount the brush head. The brush head mounting base 2 is movably connected to the end of the handle 1 through a ball joint structure, and the brush head mounting base 2 can swing relative to the handle 1.

[0048] It is understood that the cleaning brush described in this embodiment is used in conjunction with the brush head, which can be a scouring pad or a sponge or other cleaning material.

[0049] Optionally, the ends of the brush head mounting base 2 and the brush handle 1 can also be connected by other structures such as hinge structure or universal rotation structure, which is not limited here.

[0050] In this embodiment, the brush head mounting base 2 is detachably mounted with the brush head. The end of the brush head mounting base 2 is movably connected to the end of the brush handle 1 through a ball joint structure, allowing the brush head mounting base 2 to swing more flexibly relative to the brush handle 1, thus improving the flexibility and applicability of the cleaning brush during use. For example, when cleaning the interior surface of a toilet, since the interior surface of a toilet is mostly a concave arc shape, with the brush head mounting base 1 able to swing flexibly relative to the brush handle 3, the user can more easily clean various angles.

[0051] In one embodiment, such as Figures 2-5As shown, the ball head structure includes a spherical inner cavity 11 at the end of the brush handle 1 and an end head 21 at the end of the brush head mounting seat 2. The end head 21 is disposed in the spherical inner cavity 11, and the outer wall of the end head 21 is clearance-fitted with the inner wall of the spherical inner cavity 11 so that when the brush head mounting seat 2 can swing relative to the brush handle 1, the outer wall of the end head 21 slides relative to the inner wall of the spherical inner cavity 11.

[0052] Optionally, the positions of the spherical inner cavity 11 and the end 21 can be interchanged, that is, the end of the brush handle 1 is provided with the end 21, and the end of the brush head mounting base 2 is provided with the spherical inner cavity 11, with the end 21 extending into the spherical inner cavity 11. The specific construction of the ball head structure is not limited here.

[0053] In this embodiment, the outer wall of the end 21 is fitted with the inner wall of the spherical inner cavity 11 with a clearance, so that when the brush head mounting seat 2 can swing relative to the brush handle 1, the outer wall of the end 21 and the inner wall of the spherical inner cavity 11 slide relative to each other, thereby realizing the movable connection between the brush handle 1 and the brush head mounting seat 2. It has the characteristics of simple structure, low cost and high reliability.

[0054] Optionally, the end 21 can be a spherical structure or a hemispherical structure. Preferably, the end 21 is a hemispherical structure to save material costs. In addition, the top surface of the hemispherical structure can also be provided with a bowl-shaped groove to further save material costs.

[0055] In one embodiment, such as Figures 2-5 As shown, the brush handle 1 is composed of at least a first handle body 12 with a first arc-shaped port and a second handle body 13 with a second arc-shaped port, which are detachably connected together. The first arc-shaped port and the second arc-shaped port are engaged to form a spherical inner cavity 11. The first handle body 12 and the second handle body 13 are detachably connected, which facilitates the assembly and disassembly of the ball head structure.

[0056] Specifically, such as Figure 2 As shown, the brush handle 1 can also be composed of a first handle body 12 with a first arc-shaped port, a second handle body 13 with a second arc-shaped port, and a third handle body 14 with a sliding groove 15. The first handle body 12 and the second handle body 13 are detachably connected and detachably linked to the third handle body 14.

[0057] Optionally, the spherical inner cavity 11 may also be integrally formed inside the brush handle 1.

[0058] In this embodiment, the brush handle 1 is divided into multiple detachable sections, which facilitates the assembly and disassembly of the ball head structure and other structures, and also makes it easier to store and transport the cleaning brush.

[0059] In one embodiment, such as Figures 2-5As shown, the cleaning brush also includes a handle sleeve 3, which is fitted and fixed to the outer wall of the handle formed after the first handle body 12 and the second handle body 13 are connected, thereby further strengthening the connection strength between the first handle body 12 and the second handle body 13. The handle sleeve 3 can be snapped or threaded to the outer wall of the handle, and the specific connection method is not limited.

[0060] In one embodiment, such as Figures 2-5 As shown, the outer wall of the handle has a rotating threaded protrusion, and the handle sleeve 3 has a rotating threaded groove that matches the rotating threaded protrusion. The handle sleeve 3 is threadedly connected to the outer wall of the handle, thereby further strengthening the connection between the first handle body 12 and the second handle body 13. Optionally, the handle sleeve 3 can also be fixedly connected to the outer wall of the handle by means of fasteners or other connecting parts.

[0061] In this embodiment, the handle sleeve 3 is threaded to the outer wall of the handle, which is simple, reliable and durable.

[0062] In one embodiment, such as Figures 2-5 As shown, the brush head mounting base 2 is provided with a needle-like structure, which is used to fix the brush head to the brush head mounting base 2 by inserting the needle-like structure into the brush head.

[0063] The needle-like structure can be fixedly connected to the bottom of the brush head mounting base 2, or it can be movably connected to the bottom of the brush head mounting base 2.

[0064] For example, such as Figure 4 , Figure 5 As shown, the needle-like structure is movably connected to the bottom of the brush head mounting base 2. Specifically, the cleaning brush also includes a drive component that can be driven to move, which is disposed on the brush handle 1. The brush head mounting base 2 also includes a connecting structure 23 and a rotating structure 24. The connecting structure 23 is disposed inside the brush head mounting base 2 and is connected to the drive component for transmission. The rotating structure 24 has a rotating shaft 241, and its overall structure is similar to a seesaw. The needle-like structure 22 is fixedly connected to one end of the rotating structure 24. When the drive component is driven to move along the brush handle 1, it drives the connecting structure 23 to move, so that the side of the connecting structure 23 away from the brush handle 1 is driven to move, driving the other end of the rotating structure 24 to rotate, which in turn drives the needle-like structure 22 to rotate in the same direction, so that the needle-like structure 22 can insert into the brush head or clamp and fix the brush head after inserting into the brush head.

[0065] In this embodiment, a needle-like structure is inserted to fix the brush head, avoiding direct contact between the user and the brush head. The operation is simple and the brush head replacement is also convenient.

[0066] According to an embodiment of the present invention, another aspect, a cleaning brush is also provided, such as... Figures 2-5As shown, the cleaning brush includes a handle 1, a drive component that can be driven to move, and a brush head mounting base 2. The drive component is disposed on the handle 1, and the brush head mounting base 2 is used to mount the brush head. The brush head mounting base 2 is movably connected to the end of the handle 1, and the brush head mounting base 2 can swing relative to the handle 1. When the drive component is driven to move along the handle 1, it causes the brush head mounting base 2 to swing to a fixed position and lock.

[0067] Optionally, when the driving member is driven to move axially along the brush handle 1, it causes the brush head mounting seat 2 to swing to a fixed position and lock. Alternatively, when the driving member is driven to move radially or circumferentially along the brush handle 1, it causes the brush head mounting seat 2 to swing to a fixed position and lock. The direction of movement of the driving member is not limited here.

[0068] Understandably, the brush head mounting base 2 can swing flexibly relative to the brush handle 1 in its natural state, or it can swing to a fixed position and lock under the drive of the driving component. Users can choose the usage method according to their actual needs. The cleaning brush in this embodiment can not only flexibly adapt to cleaning in various scenarios and from various angles, but also better clean stubborn stains when the brush head mounting base 2 is locked in the position, while improving the flexibility, applicability, and cleaning effect on stubborn stains. For example, when cleaning the inner surface of the toilet, since the inner surface of the toilet is mostly concave and curved, the user can more easily clean from various angles when the brush head mounting base 2 can swing flexibly relative to the brush handle 1. If it is necessary to clean stubborn stains on the toilet surface, the user can drive the driving component to swing the brush head to a fixed position and lock it. This allows the user to apply more force and more easily increase the friction during cleaning, thereby better cleaning stubborn stains.

[0069] In one embodiment, such as Figures 2-5 As shown, the driving component includes a push rod 4 disposed inside the brush handle 1, the push rod 4 having a driving end 41. The push rod 4 is driven to move axially along the brush handle 1 until the driving end 41 extends out from the end of the brush handle 1 near the brush head mounting seat 2 and extends into the brush head mounting seat 2, thereby causing the brush head mounting seat 2 to swing to a fixed position and lock.

[0070] Optionally, the drive end 41 can also be movably connected to the brush head mounting 2. When the push rod 4 is driven to move away from the brush head mounting 2 along the axial direction of the brush handle 1, the drive end 41 pulls the brush head mounting 2 to swing to a fixed position and locks it.

[0071] In this embodiment, the brush head mounting base 2 is driven to swing to a fixed position and locked by the push rod 4. No other complex driving structure is required, which has the characteristics of simple structure, low cost and high reliability.

[0072] In one embodiment, such as Figures 2-5As shown, the driving component also includes a push button 5 connected to the push rod 4. The brush handle 1 is provided with a sliding groove 15, and the push button 5 is slidably disposed in the sliding groove 15, with the end of the push button 5 located outside the brush handle 1. When the end of the push button 5 is driven to slide along the sliding groove 15, the push button 5 drives the push rod 4 to move axially along the brush handle 1.

[0073] Optionally, the push button 5 can also be rotatably connected to the brush handle 1, similar to a "trigger" structure. When the end of the push button 5 is driven to rotate, the push button 5 can drive the push rod 4 to move along the axial direction of the brush handle 1.

[0074] In this embodiment, the user only needs to use one hand to control the movement of the push rod 4 by pushing the button 5, which is convenient and quick to use.

[0075] In one embodiment, such as Figure 4 , Figure 5 As shown, the brush head mounting base 2 has a guide surface 231. When the driving member moves along the brush handle 1 until the driving end 41 abuts against the guide surface 231, and continues to move so that the driving end 41 slides along the guide surface 231, the brush head mounting base 2 swings relative to the brush handle 1 under the force exerted by the driving end 41 on the guide surface 231. When the driving end 41 slides along the guide surface 231 to a reference position on the guide surface 231, the brush head mounting base 2 swings to a fixed position and locks.

[0076] Optionally, the brush head mounting base 2 has a guide structure, which can replace the function of a guide surface 231. The driving component moves along the axial direction of the brush handle 1, causing the guide structure to move, thereby causing the brush head mounting base 2 to swing relative to the brush handle 1 until it reaches a fixed position and locks in place. Compared with other complex guide structures, the guide surface 231 in this embodiment has the characteristics of simple structure, low cost, and high reliability.

[0077] In one embodiment, such as Figure 4 , Figure 5 As shown, the guide surface 231 is the bottom wall of the arc-shaped groove formed by the recess of the brush head mounting seat 2, and the reference position is the lowest point of the bottom wall surface.

[0078] Optionally, the bottom wall of the groove can be V-shaped, U-shaped, or other shapes. In this embodiment, the drive end 41 abuts against the bottom wall of the arc-shaped groove, making it slide more smoothly along the guide surface 231, thus improving the user's feel during operation and enhancing the user experience.

[0079] In one embodiment, such as Figure 4 , Figure 5As shown, the drive end 41 has an arc-shaped contact 411. When the arc-shaped contact 411 abuts against the guide surface 231 and slides along the guide surface 231, the brush head mounting seat 2 swings relative to the brush handle 1. When the arc-shaped contact 411 slides along the guide surface 231 to the reference position of the guide surface 231, the brush head mounting seat 2 swings to a fixed position and locks.

[0080] Alternatively, the contact can also be in other shapes besides arcuate ones, such as conical.

[0081] In this embodiment, after the arc-shaped contact 411 comes into contact with the guide surface 231, it slides more smoothly along the guide surface 231, which makes the user feel better during operation and improves the user experience.

[0082] In one embodiment, such as Figure 4 , Figure 5 As shown, the brush head mounting base 2 also includes a connecting structure 23, which is disposed inside the brush head mounting base 2 and is connected to the driving component. When the driving component is driven to move along the brush handle 1, it drives the connecting structure 23 to move, causing the side of the connecting structure 23 away from the brush handle 1 to move, and thus connecting the brush head. At least a portion of the connecting structure 23 on the side closest to the brush handle 1 protrudes from the brush head mounting base 2, and a guide surface 231 is disposed at the end of the protruding portion of the connecting structure 23.

[0083] This embodiment cleverly integrates structures with different functions. The guide surface 231 is set at the end of the extended part of the connecting structure 23, so that the driving component can control the brush head swing while also controlling the brush head mounting seat 2 to connect the brush head. This achieves two goals at once, not only reducing the cost of the structure, but also simplifying the user's operation of the cleaning brush and greatly facilitating the user's use.

[0084] In one embodiment, such as Figure 4 , Figure 5 As shown, the brush head mounting base 2 and the brush handle 1 are movably connected by a ball-head structure. The ball-head structure includes a spherical inner cavity 11 at the end of the brush handle 1 and an end 21 provided on the brush head mounting base 2. The end 21 is disposed in the spherical inner cavity 11 and has a bowl-shaped groove. The end 21 has a hollow cavity, and at least a portion of the connecting structure 23 on the side near the brush handle 1 protrudes from the brush head mounting base 2 through the hollow cavity, such that the protruding portion of the connecting structure 23 is located in the bowl-shaped groove.

[0085] This embodiment cleverly integrates structures with different functions, enabling the drive component to control the brush head swing while simultaneously controlling the brush head mounting base 2 to connect the brush head. This achieves two goals at once, reducing structural costs and simplifying user operation of the cleaning brush, greatly facilitating user use.

[0086] In one embodiment, such as Figures 2-5 As shown, the cleaning brush also includes a reset structure 6, which is connected to the drive component and is used to drive the drive component to reset after it moves along the brush handle 1.

[0087] Among them, the reset structure 6 can be an elastic element such as a spring or torsion spring, or other driving mechanism.

[0088] For example, such as Figure 4 , Figure 5 As shown, the reset structure 6 may include an elastic element, one end of which abuts against the brush handle 1, and the other end of which abuts against the driving element. When the driving element is driven to move axially along the brush handle 1, the elastic element can be compressed to store force. When the elastic element extends to release the force, it can drive the driving element to reset.

[0089] In this embodiment, the reset structure 6 or the elastic element can automatically drive the drive component to reset after being driven, eliminating the need for manual reset by the user and simplifying the process. The elastic element provides the reset force through its own elasticity, offering simplicity, reliability, and a long lifespan.

[0090] For ease of understanding, the following is combined with Figures 1-5 The operating principle of the embodiments of this application is explained in detail.

[0091] Specifically, the cleaning brush in this application includes a brush handle 1, a brush head mounting base 2, a push rod 4, a push button 5, and a reset structure 6.

[0092] The brush handle 1 is provided with a sliding groove 15, the push button 5 is slidably disposed in the sliding groove 15, and the end of the push button 5 is located outside the brush handle 1. The push rod 4 is disposed inside the brush handle 1 and abuts against the push button 5. The reset structure 6 is in transmission cooperation with the push rod 4.

[0093] The brush head mounting base 2 and the end of the brush handle 1 are movably connected via a ball-head structure. The ball-head structure includes a spherical inner cavity 11 at the end of the brush handle 1 and an end head 21 at the end of the brush head mounting base 2. The end head 21 is disposed in the spherical inner cavity 11, and the outer wall of the end head 21 is clearance-fitted with the inner wall of the spherical inner cavity 11. The end head 21 has a bowl-shaped groove. The brush head mounting base 2 also includes a needle-like structure 22, a connecting structure 23, and a rotating structure 24. The connecting structure 23 is disposed inside the brush head mounting base 2 and is drively connected to the push rod 4. The rotating structure 24 has a rotating shaft 241, and its overall shape is similar to a seesaw. The needle-like structure 22 is fixedly connected to one end of the rotating structure 24. The end head 21 has a hollow cavity. At least a portion of the connecting structure 23 on the side near the brush handle protrudes from the brush head mounting base through the hollow cavity, such that the protruding portion of the connecting structure 23 is located in the bowl-shaped groove. A guide surface 231 is disposed at the end of the protruding portion of the connecting structure 23.

[0094] When using the cleaning brush of this application, the user can push the push button 5 along the sliding groove 15 on the brush handle 1 towards the brush head mounting seat 2, causing the push rod 4 to move towards the brush head mounting seat 2, thus storing force in the second reset structure. Simultaneously, the push rod 4 abuts against the guide surface 231 and slides along the guide surface 231 to the reference point. On one hand, this causes the connecting structure 23 to move, driving the side of the connecting structure 23 away from the brush handle 1 to rotate, which in turn drives the needle-like structure 22 to rotate in the same direction, allowing the needle-like structure 22 to insert into the brush head or clamp and fix the brush head after insertion. On the other hand, it causes the brush head mounting seat 2 to swing relative to the brush handle 1 until it reaches a fixed position and locks in place. This application solves the problem in related technologies where the rotation angle of the brush head mounted on the brush head mounting seat is limited, resulting in insufficient flexibility and applicability in complex cleaning scenarios, thus improving the flexibility and applicability of the cleaning brush during use.

[0095] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
