A tool handle and cleaning brush

Abstract

This invention provides a tool handle and a cleaning brush. The tool handle includes a housing and a clamping structure. The clamping structure is used to clamp a brush head that extends into the housing through a first opening. The clamping structure includes a pushing component, an elastic element, a first clamping element, and a second clamping element. The middle portions of the first clamping element and the second clamping element are hinged together. The pushing component abuts against the first clamping element and the second clamping element respectively. The pushing component is driven to move along the centerline of the housing in a direction closer to or away from the first opening, thereby causing the first clamping element and the second clamping element to open or close, thereby releasing the first clamping element and the second clamping element from clamping or clamping the brush head. The elastic element is used to apply an elastic force to the pushing component to move away from the first opening. The elastic element in this application ensures that the clamping component can reliably clamp the brush head during cleaning, preventing the brush head from falling off the tool handle.

Description

Technical Field

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

[0002] Existing cleaning tools with replaceable brush heads consist of a detachable tool handle and a brush head. When the brush head is damaged, it can be directly replaced with a new brush head, or different sizes of brush heads can be replaced according to different usage scenarios.

[0003] However, the existing tool handles cannot reliably hold the brush head in place, making it easy for the brush head to detach from the tool handle when cleaning. This forces users to stop cleaning and reattach the detached brush head to the tool handle, causing great inconvenience to users. Summary of the Invention

[0004] Therefore, the main objective of this invention is to provide a tool handle and cleaning brush that can reliably hold the brush head.

[0005] To achieve the above objectives, the present invention provides a tool handle, comprising:

[0006] A housing, wherein a first opening communicating with the interior of the housing is provided on the housing; and

[0007] A clamping structure is disposed within the housing, the clamping structure being used to clamp a brush head that extends into the housing through the first opening portion;

[0008] The clamping structure includes a propulsion assembly, an elastic element, a first clamping element, and a second clamping element. The middle portions of the first clamping element and the second clamping element are hinged together. The propulsion assembly abuts against the first clamping element and the second clamping element respectively, driving the propulsion assembly to move along the centerline of the housing towards or away from the first opening, thereby causing the first clamping element and the second clamping element to open or close, thereby releasing the first clamping element and the second clamping element from clamping or clamping the brush head. One end of the elastic element abuts against the inner wall of the housing, and the other end of the elastic element abuts against the propulsion assembly. The elastic element is used to apply an elastic force to the propulsion assembly to move away from the first opening.

[0009] Preferably, the end of the first clamping member near the first opening is the first clamping end, and the other end of the first clamping member is the first abutting end. The end of the second clamping member near the first opening is the second clamping end, and the other end of the second clamping member is the second abutting end. The pushing component abuts against the first abutting end and the pushing component abuts against the second abutting end, driving the pushing component to move along the center line of the housing towards or away from the first opening, so as to drive the first abutting end and the second abutting end to move closer or further away from each other, thereby causing the first clamping end and the second clamping end to move further away or closer to each other, so as to release the clamping end from or release the clamping end from the brush head.

[0010] Preferably, the propulsion assembly has a first guide groove and a second guide groove, and the distance between the first guide groove and the second guide groove gradually decreases along the direction from the end of the propulsion assembly near the first opening to the end of the propulsion assembly away from the first opening. The first abutting end of the first clamping member is accommodated in the first guide groove, and the second abutting end of the second clamping member is accommodated in the second guide groove. The propulsion assembly is driven to move along the center line of the housing towards or away from the first opening, so as to drive the first abutting end to move along the first guide groove, and at the same time drive the second abutting end to move along the second guide groove, thereby making the first abutting end and the second abutting end move closer or further away from each other, and thus making the first clamping end and the second clamping end move further away or closer to each other, so as to release the clamping end from or release the clamping end from the brush head.

[0011] Preferably, the first guide groove includes a first sub-groove, a second sub-groove, and a third sub-groove connected in sequence, and the second guide groove includes a fourth sub-groove, a fifth sub-groove, and a sixth sub-groove connected in sequence. Along the direction from the end of the propulsion assembly near the first opening to the end of the propulsion assembly away from the first opening, the distance between the first sub-groove and the fourth sub-groove remains constant, the distance between the second sub-groove and the fifth sub-groove gradually decreases, and the distance between the third sub-groove and the sixth sub-groove remains constant. This drives the propulsion assembly to move along the centerline of the housing towards or away from the first opening, thereby causing the first abutting end to move sequentially along the first sub-groove, the second sub-groove, the third sub-groove, the fourth sub-groove, the fifth sub-groove, and the sixth sub-groove. The second and third slots move or sequentially move along the third, second, and first slots, simultaneously causing the second abutment end to move sequentially along the fourth, fifth, and sixth slots or sequentially along the sixth, fifth, and fourth slots, so that the first and second clamping ends sequentially pass through states of maintaining clamping the brush head, releasing clamping the brush head, and maintaining the release of clamping the brush head; or the first and second clamping ends sequentially pass through states of releasing the clamping of the brush head, releasing the clamping of the brush head, and maintaining the clamping of the brush head; or

[0012] The first guide groove includes a first sub-groove and a second sub-groove connected in sequence. The second guide groove includes a fourth sub-groove and a fifth sub-groove connected in sequence. Along the direction from the end of the propulsion assembly near the first opening to the end of the propulsion assembly away from the first opening, the distance between the first sub-groove and the fourth sub-groove remains constant, while the distance between the second sub-groove and the fifth sub-groove gradually decreases. This drives the propulsion assembly to move along the centerline of the housing towards or away from the first opening, thereby causing the first abutting end to move sequentially along the first sub-groove and the second sub-groove, and simultaneously causing the second abutting end to move sequentially along the fourth sub-groove and the fifth sub-groove. This allows the first clamping end and the second clamping end to sequentially maintain and release the clamping state of the brush head, or to sequentially maintain contact with and release the clamping state of the brush head.

[0013] Preferably, the propulsion assembly includes a first propulsion rod, a second propulsion rod, and a sliding button. The first propulsion rod and the second propulsion rod are detachably connected. The first guide groove and the second guide groove are located on the first propulsion rod. The sliding button extends into the housing and is connected to the end of the second propulsion rod away from the first propulsion rod. Driving the sliding button to move relative to the housing causes the second propulsion rod and the first propulsion rod to move synchronously along the centerline of the housing in a direction closer to or away from the first opening.

[0014] Preferably, the end of the propulsion assembly facing the first opening is provided with a stop, the stop being used to abut the brush head when the first clamping member and the second clamping member release their grip on the brush head, so that the brush head exits the housing through the first opening.

[0015] Preferably, the propulsion assembly has a receiving groove, a positioning post is provided on the inner wall of the receiving groove, a limiting member is provided on the inner wall of the housing, the limiting member extends into the receiving groove, the elastic member is located in the receiving groove, one end of the elastic member abuts against the limiting member, and the other end of the elastic member is sleeved on the positioning post and abuts against the inner wall of the receiving groove.

[0016] Preferably, the housing includes a detachably connected gripping assembly and a clamping assembly. The first opening is located at the end of the clamping assembly away from the gripping assembly. The clamping assembly has a second opening at the end away from the first opening. The gripping assembly can extend into the clamping assembly through the second opening. The first clamping member and the second clamping member are disposed within the clamping assembly. The pushing assembly and the elastic member are disposed within the gripping assembly and / or the clamping assembly.

[0017] Preferably, the clamping assembly includes a first sub-shell and a second sub-shell connected to each other. The first sub-shell is detachably connected to the gripping assembly. The first opening is located at the end of the first sub-shell away from the gripping assembly, and the second opening is located at the end of the first sub-shell away from the first opening. The second sub-shell does not have the first opening and the second opening. The gripping assembly can extend into the first sub-shell through the second opening.

[0018] And / or the gripping assembly includes a third sub-shell and a fourth sub-shell connected to each other, the third sub-shell and the fourth sub-shell being able to simultaneously extend into the clamping assembly through the second opening.

[0019] To achieve the above objectives, the present invention provides a cleaning brush, including a brush head and the aforementioned tool handle.

[0020] Advantages of the technical solution of this invention: The driving propulsion assembly moves along the center line of the housing towards the direction of the first opening, thereby opening the first clamping member and the second clamping member. Then, the brush head is inserted into the housing through the first opening. The driving propulsion assembly is then moved along the center line of the housing away from the first opening, thereby closing the first clamping member and the second clamping member. This allows the first clamping member and the second clamping member to clamp the brush head. Since the elastic member of this application can apply an elastic force to the propulsion assembly to move away from the first opening, when the first clamping member and the second clamping member clamp the brush head for cleaning, without applying external force, the elastic member of this application applies an elastic force to the propulsion assembly, causing the propulsion assembly to tend to move away from the first opening. This keeps the first clamping member and the second clamping member in a closed state, ensuring that the first clamping member and the second clamping member can reliably clamp the brush head and prevent the brush head from falling off the tool handle.

[0034] like Figure 1-3 As shown, a tool handle includes a housing 200 and a clamping structure 100. A first opening 2111 communicating with the interior of the housing 200 is formed on the housing 200. The clamping structure 100 is disposed within the housing 200 and is used to clamp a brush head 300 that partially extends into the housing 200 through the first opening 2111. The clamping structure 100 includes a pushing assembly 130, an elastic member 140, a first clamping member 110, and a second clamping member 120. The middle portion of the first clamping member 110 and the middle portion of the second clamping member 120 are hinged together. The pushing assembly 130 is connected to both the first clamping member 110 and the second clamping member 120. The clamping member 120 abuts against and drives the propulsion assembly 130 to move along the center line of the housing 200 toward or away from the first opening 2111, thereby causing the first clamping member 110 and the second clamping member 120 to open or close, thereby causing the first clamping member 110 and the second clamping member 120 to release or clamp the brush head 300. One end of the elastic member 140 abuts against the inner wall of the housing 200, and the other end of the elastic member 140 abuts against the propulsion assembly 130. The elastic member 140 is used to apply an elastic force to the propulsion assembly 130 to move away from the first opening 2111.

[0035] The drive propulsion assembly 130 moves along the centerline of the housing 200 toward the first opening 2111, thereby opening the first clamping member 110 and the second clamping member 120. The brush head 300 then partially extends into the housing 200 through the first opening 2111. The drive propulsion assembly 130 then moves along the centerline of the housing 200 away from the first opening 2111, thereby closing the first clamping member 110 and the second clamping member 120, thus clamping the brush head 300. Because the elastic member 140 of this application can apply force to the propulsion assembly 130 in a direction away from the first opening 2111... The elastic force that moves in the direction of the first opening 2111 causes the first clamping member 110 and the second clamping member 120 to clamp the brush head 300 for cleaning work. Without the application of external force, the elastic member 140 of this application applies an elastic force to the pushing assembly 130. The pushing assembly 130 tends to move away from the first opening 2111, so that the first clamping member 110 and the second clamping member 120 are always kept in a closed state. Thus, the first clamping member 110 and the second clamping member 120 can reliably clamp the brush head 300, so that the brush head 300 will not fall off the tool handle.

[0036] Furthermore, such as Figure 4 As shown, the first clamping member 110 has a first clamping end 111 near the first opening 2111 and a first abutting end 112 near the other end. The second clamping member 120 has a second clamping end 121 near the first opening 2111 and a second abutting end 122 near the other end. The pushing component 130 abuts against the first abutting end 112 and the second abutting end 122, driving the pushing component 130 to move along the center line of the housing 200 towards or away from the first opening 2111, thereby causing the first abutting end 112 and the second abutting end 122 to move closer to or further away from each other, thus causing the first clamping end 111 and the second clamping end 122 to move closer to or further away from each other. 21. The first clamping end 111 and the second clamping end 121 move away from or close to each other so that the first clamping end 111 and the second clamping end 121 release or clamp the brush head 300. Specifically, when the first clamping member 110 and the second clamping member 120 clamp the brush head 300, under the elastic force of the elastic member 140, the pushing component 130 tends to move away from the first opening 2111, so that the first abutting end 112 and the second abutting end 122 are kept far apart, thereby keeping the first clamping end 111 and the second clamping end 121 close together, so that the first clamping member 110 and the second clamping member 120 can reliably clamp the brush head 300 through the first clamping end 111 and the second clamping end 121.

[0037] In this embodiment, the elastic element 140 is always in a compressed state, so that the elastic element 140 can continuously apply an elastic force to the propulsion assembly 130 in a direction away from the first opening 2111. Specifically, the elastic element 140 may be, but is not limited to, a spring.

[0038] In this embodiment, as Figure 4 As shown, the tool handle also includes a hinge shaft 215, which is disposed on the inner wall of the housing 200. The middle part of the first clamping member 110 and the middle part of the second clamping member 120 are rotatably sleeved on the hinge shaft 215, thereby realizing the hinge connection between the middle part of the first clamping member 110 and the middle part of the second clamping member 120.

[0039] Furthermore, such as Figure 4 As shown, the propulsion assembly 130 has a first guide groove 1311 and a second guide groove 1312. The distance between the first guide groove 1311 and the second guide groove 1312 gradually decreases along the direction from the end of the propulsion assembly 130 near the first opening 2111 to the end of the propulsion assembly 130 away from the first opening 2111. The first abutting end 112 of the first clamping member 110 is accommodated in the first guide groove 1311, and the second abutting end 122 of the second clamping member 120 is accommodated in the second guide groove 1312. Within 12, the drive propulsion assembly 130 moves along the centerline of the housing 200 toward the direction of approaching or moving away from the first opening 2111, thereby driving the first abutment end 112 to move along the first guide groove 1311, and simultaneously driving the second abutment end 122 to move along the second guide groove 1312, thereby causing the first abutment end 112 and the second abutment end 122 to move closer or further away from each other, and further causing the first clamping end 111 and the second clamping end 121 to move further away or closer to each other, so that the first clamping end 111 and the second clamping end 121 release from clamping the brush head 300 or clamp the brush head 300.

[0040] Specifically, when the first clamping member 110 and the second clamping member 120 clamp the brush head 300, under the elastic force of the elastic member 140, the pushing component 130 tends to move away from the first opening 2111, making it impossible for the pushing component 130 to move towards the first opening 2111. This ensures that the first clamping member 110 and the second clamping member 120 are reliably held in the state of clamping the brush head 300 through the first clamping end 111 and the second clamping end 121.

[0041] Furthermore, such as Figure 5As shown, the first guide groove 1311 includes a first sub-groove 13111, a second sub-groove 13112, and a third sub-groove 13113 connected in sequence. The second guide groove 1312 includes a fourth sub-groove 13121, a fifth sub-groove 13122, and a sixth sub-groove 13123 connected in sequence. Along the direction from the end of the propulsion assembly 130 near the first opening 2111 to the end of the propulsion assembly 130 away from the first opening 2111, the distance between the first sub-groove 13111 and the fourth sub-groove 13121 remains constant. The distance between the second sub-groove 13112 and the fifth sub-groove 13122 gradually decreases, while the distance between the third sub-groove 13113 and the sixth sub-groove 13123 remains constant. This drives the propulsion assembly 130 to move along the centerline of the housing 200 towards or away from the first opening 2111, thereby driving the first abutment end 11. 2 moves sequentially along the first groove 13111, the second groove 13112, and the third groove 13113, or sequentially along the third groove 13113, the second groove 13112, and the first groove 13111, simultaneously driving the second abutment end 122 to move sequentially along the fourth groove 13121, the fifth groove 13122, and the sixth groove 13123, or sequentially along the sixth groove 13123, the fifth groove 13122, and the fourth groove 13111. 21 is moved such that the first clamping end 111 and the second clamping end 121 are sequentially in a state of holding the brush head 300, releasing the clamping of the brush head 300, and holding the brush head 300 in a state of releasing the clamping, or the first clamping end 111 and the second clamping end 121 are sequentially in a state of holding the brush head 300 in a state of releasing the clamping, releasing the clamping of the brush head 300, and holding the brush head 300 in a state of releasing the clamping.

[0042] Specifically, when it is necessary to release the gripping of the brush head 300, the drive propulsion assembly 130 moves along the centerline of the housing 200 toward the direction closer to the first opening 2111, thereby causing the first abutment end 112 to move sequentially along the first slot 13111, the second slot 13112, and the third slot 13113, while simultaneously causing the second abutment end 122 to move sequentially along the fourth slot 13121, the fifth slot 13122, and the sixth slot 13123. When the first abutment end 112 moves along the first slot 13111 and the second abutment end 122 moves along the fourth slot 13121, the distance between the first abutment end 112 and the second abutment end 122 remains unchanged, so that the first clamping end 111 and the second clamping end 121 maintain the gripping of the brush head 300. When the first abutment end 112 moves along the second slot 13112 and the second abutment end 122 moves along the fifth slot 13122, the first... The distance between the abutment end 112 and the second abutment end 122 gradually decreases, so that the first clamping end 111 and the second clamping end 121 gradually release the clamping of the brush head 300. When the first abutment end 112 moves along the third groove 13113 and the second abutment end 122 moves along the sixth groove 13123, the distance between the first abutment end 112 and the second abutment end 122 remains unchanged, so that the first clamping end 111 and the second clamping end 121 remain in the state of releasing the clamping of the brush head 300. When it is necessary to clamp the brush head 300, the drive propulsion assembly 130 moves along the center line of the housing 200 in a direction away from the first opening 2111. The switching process between the first clamping member 110 and the second clamping member 120 in different states is the opposite of the switching process between the first clamping member 110 and the second clamping member 120 in different states when it is necessary to release the clamping of the brush head 300. The first slot 13111 and the fourth slot 13121 of this application enable the first clamping member 110 and the second clamping member 120 to be reliably held in the state of clamping the brush head 300; the third slot 13113 and the sixth slot 13123 of this application enable the first clamping member 110 and the second clamping member 120 to be reliably held in the state of unclamping the brush head 300.

[0043] In other embodiments, such as Figure 5As shown, the first guide groove 1311 includes a first sub-groove 13111 and a second sub-groove 13112 connected in sequence. The second guide groove 1312 includes a fourth sub-groove 13121 and a fifth sub-groove 13122 connected in sequence. Along the direction from the end of the propulsion assembly 130 near the first opening 2111 to the end of the propulsion assembly 130 away from the first opening 2111, the distance between the first sub-groove 13111 and the fourth sub-groove 13121 remains constant, while the distance between the second sub-groove 13112 and the fifth sub-groove 13122 gradually decreases. This drives the propulsion assembly 130 to move along the centerline of the housing 200 towards or away from the first opening 2111, thereby causing the first abutment end 112 to move sequentially along the first... The second groove 13111 and the second groove 13112 move or move sequentially along the second groove 13112 and the first groove 13111, while simultaneously driving the second abutment end 122 to move sequentially along the fourth groove 13121 and the fifth groove 13122 or sequentially along the fifth groove 13122 and the fourth groove 13121, so that the first clamping end 111 and the second clamping end 121 sequentially maintain the clamping state of the brush head 300 and release the clamping state of the brush head 300, or sequentially release the clamping state of the brush head 300 and maintain the clamping state of the brush head 300. Specifically, in this embodiment, only the third groove 13113 and the sixth groove 13123 are reduced.

[0044] Furthermore, such as Figure 1-2 As shown, the propulsion assembly 130 includes a first propulsion rod 131, a second propulsion rod 132, and a sliding button 133. The first propulsion rod 131 and the second propulsion rod 132 are detachably connected. The first guide groove 1311 and the second guide groove 1312 are located on the first propulsion rod 131. The sliding button 133 extends into the housing 200 and is connected to the end of the second propulsion rod 132 away from the first propulsion rod 131. Driving the sliding button 133 to move relative to the housing 200 causes the second propulsion rod 132 and the first propulsion rod 131 to move synchronously along the centerline of the housing 200. The slider moves synchronously towards or away from the first opening 2111. Specifically, the slider 133 allows the user to directly control the first push rod 131 and the second push rod 132 by hand, thereby controlling the first clamping member 110 and the second clamping member 120. In addition, since the first push rod 131 and the second push rod 132 are detachably connected, they can be disassembled when the tool handle is not in use or when the tool handle needs to be transported, thereby reducing the space occupied by the first push rod 131 and the second push rod 132.

[0045] Furthermore, such as Figure 5 As shown, the first clamping member 110 has a first clearance hole 113 at one end near the first abutting end 112, so that when the first abutting end 112 moves along the first guide groove 1311, the side wall of the first clamping member 110 is prevented from interfering with the first push rod 131, thus preventing the first clamping member 110 from being stuck and unable to move; the second clamping member 120 has a second clearance hole 123 at one end near the second abutting end 122, so that when the second abutting end 122 moves along the second guide groove 1312, the side wall of the second clamping member 120 is prevented from interfering with the first push rod 131, thus preventing the second clamping member 120 from being stuck and unable to move.

[0046] Furthermore, the centerline of the first clamping member 110 is parallel to the axis of the first slot 13111, so as to prevent the first abutting end 112 from directly hitting the second slot 13112 and getting stuck when it moves along the first guide slot 1311, and further to prevent the side wall of the first clamping member 110 from interfering with the first push rod 131; the centerline of the second clamping member 120 is parallel to the axis of the fourth slot 13121, so as to prevent the second abutting end 122 from directly hitting the fifth slot 13122 and getting stuck when it moves along the second guide slot 1312, and further to prevent the side wall of the second clamping member 120 from interfering with the first push rod 131.

[0047] Furthermore, the first abutment end 112 is cylindrical, and the diameter of the first abutment end 112 is adapted to the groove width of the first guide groove 1311, thereby facilitating the movement of the first abutment end 112 along the first guide groove 1311; the second abutment end 122 is cylindrical, and the diameter of the second abutment end 122 is adapted to the groove width of the second guide groove 1312, thereby facilitating the movement of the second abutment end 122 along the second guide groove 1312.

[0048] Furthermore, such as Figure 3 and Figure 4As shown, the push assembly 130 has a stop 134 at one end facing the first opening 2111. The stop 134 is used to abut the brush head 300 when the first clamping member 110 and the second clamping member 120 release their grip on the brush head 300, so that the brush head 300 exits the housing 200 through the first opening 2111. Specifically, when it is necessary to remove the brush head 300 from the tool handle, the push assembly 130 is driven to move along the center line of the housing 200 toward the direction closer to the first opening 2111, so that the first clamping member 110 and the second clamping member 120 release their grip on the brush head 300. At the same time, the push assembly 130 will drive the stop 134 to move toward the direction closer to the first opening 2111, so that the stop 134... Part 134 can gradually approach and abut against the brush head 300 until the brush head 300 is abutted against the outside of the housing 200 through the first opening 2111. The clamping structure 100 of this application can release the clamping of the brush head 300 and abut against the outside of the housing 200 through the abutting part 134, so that the user does not need to manually remove the brush head 300 from the tool handle. In this embodiment, the abutting part 134 is provided on the end of the first push rod 131 away from the second push rod 132. The abutting part 134 can pass between the first clamping member 110 and the second clamping member 120 to abut against the brush head 300, thereby abutting the brush head 300 against the outside of the housing 200 through the first opening 2111.

[0049] Furthermore, such as Figure 3 and Figure 4 As shown, the propulsion assembly 130 has a receiving groove 135, and a positioning post 136 is provided on the inner wall of the receiving groove. A limiting member 213 is provided on the inner wall of the housing 200, and part of the limiting member 213 extends into the receiving groove 135. An elastic member 140 is located in the receiving groove 135, and one end of the elastic member 140 abuts against the limiting member 213. The other end of the elastic member 140 is sleeved on the positioning post and abuts against the inner wall of the receiving groove 135. Specifically, when the propulsion assembly 130 is driven to move along the center line of the housing 200 toward the direction close to the first opening 2111, the elastic member 140 and the receiving groove 135... The end of the inner wall that abuts will move towards the first opening 2111 along with the push assembly 130. The end of the elastic member 140 that abuts with the limiting member 213 will be blocked and unable to move, so that the elastic member 140 is compressed. When the drive of the push assembly 130 is canceled, the elastic member 140 can apply an elastic force to the push assembly 130 to move away from the first opening 2111, so that the push assembly 130 moves away from the first opening 2111 until it drives the first clamping member 110 and the second clamping member 120 to close. In this embodiment, the receiving groove 135 is opened on the first push rod 131.

[0050] Furthermore, such as Figure 6As shown, a limiting rib 216 is provided on the inner wall of the housing 200. The limiting rib 216 is located on the side of the receiving groove 135 with an opening. The limiting rib 216 is used to block the elastic member 140 in the receiving groove 135 to prevent the elastic member 140 from detaching from the receiving groove 135. Furthermore, the receiving groove 135 has a structure with openings on both sides. There are multiple limiting ribs 216. Multiple limiting ribs 216 are spaced apart on opposite sides of the receiving groove 135 with openings to reliably block the elastic member 140 in the receiving groove 135.

[0051] Furthermore, such as Figure 1 As shown, the housing 200 is arc-shaped. Specifically, the arc shape of the housing 200 makes the part of the user holding the housing 200 form a certain angle with the brush head 300. This allows the user to more easily clean their corners when holding the housing 200 and cleaning with the brush head 300. In addition, the arc shape of the housing 200 is more aesthetically pleasing.

[0052] Furthermore, such as Figure 7 As shown, a guide groove 230 extending along the center line of the housing 200 is provided on the inner wall of the housing 200. The propulsion component 130 is partially housed in the guide groove 230. The propulsion component 130 can move along the guide groove 230 in a direction closer to or further away from the first opening 2111. Specifically, the guide groove 230 serves to guide the propulsion component 130 and also serves to position the propulsion component 130 to prevent it from shaking inside the housing 200.

[0053] Furthermore, such as Figure 1 and Figure 3 As shown, the housing 200 includes a detachably connected gripping assembly 220 and a clamping assembly 210. A first opening 2111 is located at the end of the clamping assembly 210 away from the gripping assembly 220. A second opening 2212 is provided at the end of the clamping assembly 210 away from the first opening 2111. The gripping assembly 220 can partially extend into the clamping assembly 210 through the second opening 2212. A first clamping member 110 and a second clamping member 120 are disposed within the clamping assembly 210. A pushing assembly 130 and an elastic member 140 are disposed within the gripping assembly 220 and / or the clamping assembly 210. Specifically, when the tool handle is not in use or is needed, the gripping assembly 220 and the clamping assembly 210 can be detached, thereby reducing the space occupied by the tool handle and making it easier to transport. In this embodiment, the elastic member 140 is located within the clamping assembly 210, and the limiting member 213 is disposed on the inner wall of the clamping assembly 210.

[0054] In this embodiment, as Figure 1-2As shown, the first push rod 131 is located inside the clamping assembly 210, the second push rod 132 is located inside the gripping assembly 220, and the sliding button 133 extends into the gripping assembly 220 and is connected to the end of the second push rod 132 away from the first push rod 131. Pushing the sliding button 133 can drive the second push rod 132 and the first push rod 131 to move towards or away from the first opening 2111, so that the first push rod 131 drives the first clamping member 110 and the second clamping member 120 to open or close through the first guide groove 1311 and the second guide groove 1312.

[0055] Furthermore, such as Figure 7-8 As shown, the gripping component 220 is provided with a resilient button 223, and the clamping component 210 is provided with a retaining groove 214. The resilient button 223 can be engaged in the retaining groove 214 to achieve the engagement between the gripping component 220 and the clamping component 210. Pressing the resilient button 223 will disengage it from the retaining groove 214, thereby releasing the engagement between the gripping component 220 and the clamping component 210. Specifically, when it is necessary to engage the gripping component 220 and the clamping component 210, the end of the gripping component 220 with the resilient button 223 is... The elastic button 223 extends into the clamping component 210 through the second opening 2212. When the elastic button 223 is aligned with the retaining groove 214, it will automatically pop up to accommodate the retaining groove 214, thereby realizing the engagement between the gripping component 220 and the clamping component 210. When it is necessary to separate the gripping component 220 and the clamping component 210, press the elastic button 223, and the elastic button 223 will exit the retaining groove 214 to release the engagement between the gripping component 220 and the clamping component 210. Then, the gripping component 220 can be removed from the clamping component 210 through the second opening 2212.

[0056] Furthermore, such as Figure 1 and Figure 3As shown, the clamping assembly 210 includes a first sub-shell 211 and a second sub-shell 212 connected to each other. The first sub-shell 211 is detachably connected to the gripping assembly 220. A first opening 2111 is located at the end of the first sub-shell 211 away from the gripping assembly 220, and a second opening 2212 is located at the end of the first sub-shell 211 away from the first opening 2111. The second sub-shell 212 does not have the first opening 2111 and the second opening 2212. Specifically, since the first opening 2111 and the second opening 2212 of this application are located on the first sub-shell 211, the first opening 2111 and the second opening 2212 are not formed by the first sub-shell 211 and the second sub-shell 212 enclosing each other (if the first opening 2111 and the second opening 2212 were the first sub-shell 211 and the second sub-shell 212). If the first sub-shell 211 and the second sub-shell 212 are enclosed by 12, then over time the first sub-shell 211 and the second sub-shell 212 may not be able to maintain a tight enclosure, resulting in the separation of the first sub-shell 211 and the second sub-shell 212 and the appearance of an opening. That is, the first opening 2111 and the second opening 2212 are split into two halves, which in turn causes the brush head 300 to be biased towards the first sub-shell 211 or the second sub-shell 212. Therefore, the first opening 2111 and the second opening 2212 will not be split into two halves, thus avoiding the first sub-shell 211 from failing to surround the brush head 300 and causing the brush head 300 to shift in position, and avoiding the first sub-shell 211 from failing to surround the grip component 220 and causing the grip component 220 to shift in position, due to the first opening 2111 being split into two halves.

[0057] Furthermore, such as Figure 1 As shown, the gripping assembly 220 includes a third sub-shell 221 and a fourth sub-shell 222 connected to each other. The third sub-shell 221 and the fourth sub-shell 222 can simultaneously extend into the clamping assembly 210 through the second opening 2212. Furthermore, as shown... Figure 5 As shown, the third sub-shell 221 and the fourth sub-shell 222 are both detachably connected to the first sub-shell 211.

[0058] Furthermore, such as Figure 7 As shown, the housing 200 is provided with reinforcing ribs 240 to enhance the strength of the housing 200. Furthermore, the reinforcing ribs 240 are provided on the inner wall of the housing 200, so as to enhance the strength of the housing 200 without affecting its aesthetics.

[0059] Furthermore, reinforcing ribs 240 are disposed on the inner walls of the gripping component 220 and / or the clamping component 210. In this embodiment, reinforcing ribs 240 are disposed on the inner walls of both the gripping component 220 and the clamping component 210 to simultaneously enhance the strength of the gripping component 220 and the clamping component 210.

[0060] Furthermore, reinforcing ribs 240 are provided on the first sub-shell 211 and / or the second sub-shell 212. In this embodiment, reinforcing ribs 240 are provided on both the first sub-shell 211 and the second sub-shell 212 to simultaneously enhance the strength of the first sub-shell 211 and the second sub-shell 212.

[0061] Furthermore, reinforcing ribs 240 are provided on the third sub-shell 221 and / or the fourth sub-shell 222. In this embodiment, reinforcing ribs 240 are provided on both the third sub-shell 221 and the fourth sub-shell 222 to simultaneously enhance the strength of the third sub-shell 221 and the fourth sub-shell 222.

[0062] like Figure 1 As shown, a cleaning brush includes a brush head 300 and the aforementioned tool handle. The brush head 300 extends into the housing 200 of the tool handle through a first opening 2111. The clamping structure 100 is used to clamp the brush head 300.

[0063] Furthermore, such as Figure 1 and Figure 8 As shown, the brush head 300 includes a fixing member 310 and bristles 320. The fixing member 310 extends into the housing 200 of the tool handle through the first opening 2111. The clamping structure 100 is used to clamp the fixing member 310. The bristles 320 are disposed at one end of the fixing member 310 exposed outside the housing 200. Specifically, the first clamping member 110 and the second clamping member 120 can clamp the fixing member 310 through the first clamping end 111 and the second clamping end 121.

[0064] Furthermore, such as Figure 4 and Figure 8 As shown, the end of the fixing member 310 that extends into the housing 200 has an annular groove 311. Specifically, the first clamping end 111 and the second clamping end 121 abut against the opposite sides of the annular groove 311 so that the first clamping member 110 and the second clamping member 120 can clamp the fixing member 310.

[0065] Furthermore, the bristles 320 can be cylindrical, polyhedral, or irregular in shape. Specifically, the shape of the bristles 320 can be arbitrarily selected according to actual needs, as long as the cleaning work can be achieved through the bristles 320.

[0066] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent device transformations made based on the inventive concept of the present invention and the contents of the specification and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
