Description

Technical Field

[0001] This utility model relates to the technical field of toilet brushes, and more particularly to a disposable toilet brush. Background Technology

[0002] In home bathrooms, daily cleaning of toilets relies heavily on toilet brushes. However, traditional, reusable toilet brushes are prone to leaving residue and harboring bacteria, posing hygiene and safety risks. Therefore, disposable toilet brushes with replaceable brush heads are becoming increasingly popular.

[0003] Chinese utility model patent No. 201720329527.8 discloses a novel toilet brush, including a brush head, a brush handle, and a clamping assembly. The brush handle consists of a straight rod and an arc-shaped part, with a U-shaped opening at the front end of the arc-shaped part. The clamping assembly includes an upper elastic clamp, a lower elastic clamp, a guide plate, and a push button. The push button is slidably installed on the straight rod of the brush handle, and the guide plate is installed inside the arc-shaped part. The upper and lower elastic clamps are located at the U-shaped opening. The push button is manually driven to slide, and the push button pushes the upper and lower elastic clamps to extend or retract from the U-shaped opening through the guide plate, thereby releasing or clamping the brush head accordingly. The brush head can be quickly released or clamped through the cooperation of the brush handle and the clamping assembly. After cleaning the toilet, the brush head can be directly discarded.

[0004] The novel toilet brush disclosed in this patent requires sliding a knob to open the U-shaped opening during operation. After placing the brush head in the U-shaped opening, the knob is then slid in the opposite direction to clamp the brush head in the U-shaped opening, making the operation process cumbersome. Utility Model Content

[0005] Therefore, there is a need to provide a disposable toilet brush to solve the problem of complicated brush head clamping operation of existing disposable toilet brushes.

[0006] To achieve the above objectives, the inventor provides a disposable toilet brush, comprising:

[0007] The casing has an opening at its lower end;

[0008] A pushing assembly is sleeved inside the housing. The pushing assembly includes a pushing rod and a first elastic member sleeved on the pushing rod. The first elastic member abuts against the pushing rod and the housing.

[0009] A clamping assembly is disposed below the pushing assembly. The clamping assembly includes a first clamp, a second clamp, and a second elastic member. The middle portion of the first clamp and the middle portion of the second clamp are hinged together by a hinge shaft, and both ends of the hinge shaft are connected to the housing. The lower ends of the first clamp and the second clamp are provided with outwardly folded support structures. The lower ends of the first clamp and the second clamp protrude from the opening. The second elastic member is connected to the first clamp and the second clamp to keep their lower ends separate and to clamp the brush head through the support structure. The lower end of the pushing rod is located between the first clamp and the second clamp. The pushing rod pushes downward to drive the lower ends of the first clamp and the lower ends of the second clamp to come together to disengage the brush head.

[0010] Furthermore, the second elastic element is located below the hinge shaft, and its two ends abut against the first clamp and the second clamp.

[0011] Furthermore, the length extension direction of the second elastic element is perpendicular to the length extension direction of the hinge shaft.

[0012] Furthermore, the first clamp has a first mounting hole on the side facing the second clamp, the second clamp has a second mounting hole on the side facing the first clamp, and the two ends of the second elastic member are respectively sleeved in the first mounting hole and the second mounting hole.

[0013] Furthermore, the lower end of the first clamp is provided with a first support portion that folds away from the second clamp, and the lower end of the second clamp is provided with a second support portion that folds away from the first clamp. The first support portion and the second support portion are symmetrically arranged.

[0014] Furthermore, both the first support portion and the second support portion extend in a horizontal direction.

[0015] Furthermore, the lower end of the push rod is symmetrically provided with a first guide portion and a second guide portion, with the first guide portion facing the first clamp and the second guide portion facing the second clamp.

[0016] Furthermore, the first guide portion includes a continuous first guide surface and a second guide surface, the second guide portion includes a continuous third guide surface and a fourth guide surface, both the second guide surface and the fourth guide surface extend in a vertical direction, and the first guide surface and the third guide surface are inclined.

[0017] Furthermore, the push rod includes a push rod body and a push rod sleeve. The push rod body has a guide groove extending along its length direction. The push rod sleeve includes an upper limit ring, a lower limit ring, and a connecting rod. The two ends of the connecting rod are respectively connected to the upper limit ring and the lower limit ring.

[0018] Both the upper limit ring and the lower limit ring are sleeved on the push rod body. The upper limit ring is provided with an upper guide piece adapted to the guide groove, and the lower limit ring is provided with a lower guide piece adapted to the guide groove.

[0019] The two ends of the first elastic element abut against the lower limiting ring and the housing.

[0020] Furthermore, the number of connecting rods is two or more, and the connecting rods are arranged in a circumferential array outside the push rod body;

[0021] The inner wall of the housing is adapted to guide the connecting rod, and a gap is provided between the inner wall of the housing and the push rod body.

[0022] Furthermore, the brush head includes a support portion and a cleaning portion, wherein the support portion is connected to the upper surface of the cleaning portion;

[0023] The support part has a support part through hole in the middle, and the cleaning part has a cleaning part through hole or a cleaning part groove corresponding to the position of the support part through hole;

[0024] The through hole in the support portion allows the first and second clamps to pass through when they are brought together, and also prevents the first and second clamps from detaching when they are separated.

[0025] Unlike existing technologies, the above-mentioned technical solution has the following advantages: When using this disposable toilet brush, the user holds the shell and presses the push rod, changing the relative position between the push rod and the shell. The push rod moves downward, and the upper ends of the first and second clamps gradually open, causing their lower ends to come together. After coming together, the first and second clamps can detach from or insert into the brush head. When the user removes the force applied to the push rod, the push rod returns to its initial position under the elastic force of the first elastic element. The first and second clamps also return to their separated state under the elastic force of the second elastic element. The lower ends of the first and second clamps separate to form a larger support surface, which supports and holds the brush head through the support structure. This disposable toilet brush has a simple structure, is easy to use, and is simple to operate. Attached Figure Description

[0082] Please see Figures 1-5 This embodiment provides a disposable toilet brush, comprising:

[0083] The housing 1 has an opening 11 at its lower end;

[0084] A pushing component 2 is sleeved inside the housing 1. The pushing component 2 includes a pushing rod 21 and a first elastic member 22 sleeved on the pushing rod 21. The first elastic member 22 abuts between the pushing rod 21 and the housing 1 to limit the position of the pushing rod 21 inside the housing 1.

[0085] A clamping assembly 3 is disposed below the pushing assembly. The clamping assembly 3 includes a first clamp 31, a second clamp 32, and a second elastic member 33. The middle part of the first clamp 31 and the middle part of the second clamp 32 are hinged by a hinge shaft 34, and both ends of the hinge shaft 34 are connected to the housing 1. The lower ends of the first clamp 31 and the second clamp 32 are provided with outwardly folded support structures. The lower ends of the first clamp 31 and the second clamp 32 protrude from the opening 11. The second elastic member 33 is connected to the first clamp 31 and the second clamp 32 to keep their lower ends separate and to clamp the brush head 4 through the support structure. The lower end of the pushing rod 21 is located between the first clamp 31 and the second clamp 32. The pushing rod 21 pushes downward to drive the lower ends of the first clamp 31 and the lower ends of the second clamp 32 to move closer together to disengage the brush head 4.

[0086] For ease of understanding, the upper end of the first chuck 31, the upper end of the second chuck 32, the lower end of the first chuck 31, and the lower end of the second chuck 32 are explained as follows: The upper end of the first chuck 31 and the upper end of the second chuck 32 refer to the parts of the first chuck 31 and the second chuck 32 located above the hinge shaft 34, and this part is completely set inside the housing 1; The lower end of the first chuck 31 and the lower end of the second chuck 32 refer to the parts of the first chuck 31 and the second chuck 32 located below the hinge shaft 34, and this part can be distributed inside or outside the housing 1.

[0087] like Figure 1 As shown, to facilitate the packaging and transportation of this disposable toilet brush, the housing 1 can be designed as a two-section structure, or even a multi-section structure. Taking a two-section housing as an example, housing 1 includes a first housing 12 and a second housing 13. The first housing 12 and the second housing 13 are pluggable and connected by a snap-fit ​​structure or a threaded structure at the pluggable point. The push rod 21 can pass through the first housing 12 and the second housing 13. Therefore, the push rod 21 is also designed as a two-section structure. The two push rod sections are pluggable while being connected to the first housing 12 and the second housing 13. Similarly, the connection structure between the two push rod sections can be a threaded connection or a snap-fit ​​connection. Of course, in some embodiments, the two-section housing and the two-section push rod 21 can also use an interference fit. In some embodiments, the push rod 21 can also be only set in the second housing 13 near the brush head 4 end, and the first housing 12 only provides length compensation.

[0088] like Figure 1As shown, in some embodiments, the cross-sectional area of ​​the upper end of the housing 1 is designed to be larger than that of the lower end of the housing 1. When the user uses the disposable toilet brush, he / she grips the upper end of the housing 1. The larger cross-sectional structure can correspondingly increase the contact area between the palm and the housing 1, which is beneficial for the user to hold the disposable toilet brush for toilet cleaning and improves the grip experience. In the specific implementation process, the housing 1 can be made into a stepped circular shaft structure, or it can be designed into a conical structure with the cross-sectional area gradually decreasing from top to bottom.

[0089] The first elastic element 22 is a compression spring, which is sleeved on the push rod 21. A stop 14 is provided on the inner wall of the housing 1, and a limiting structure is provided on the outer wall of the push rod 21. The compression spring is sleeved on the push rod 21 and located below the limiting structure. After the push rod 21 is sleeved on the housing 1, the other end of the compression spring abuts against the stop 14. The installation position of the push rod 21 inside the housing 1 is relatively fixed. When the user presses the push rod 21 and moves it downward, the first elastic element 22 is compressed. After the user releases the push rod 21, the first elastic element 22 returns to its initial state.

[0090] The compression spring mentioned in the instruction manual is mainly used to resist pressure. When subjected to external force, it will be compressed to store energy and return to its original shape when the external force is released.

[0091] In some embodiments, a push button 211 is provided on the side wall of the push rod 21, and the push button 211 extends through the outer surface of the housing 1. A waist-shaped hole is provided on the housing 1, the length of which is adapted to the travel distance of the push rod 21. One end of the push button 211 passes through the waist-shaped hole and connects to the push rod body 214, while the other end of the push button 211 protrudes from the surface of the housing 1. The user can operate the push button 211 by holding the disposable toilet brush. In some embodiments, the push rod 21 may extend to the upper end of the housing 1 and protrude from the housing 1, allowing the user to apply downward pressure on the push rod 21 from the upper end of the housing 1.

[0092] The hinge shaft 34 is centrally located inside the housing 1. Similarly, the clamping assembly 3 is also centrally located inside the housing 1, so that the first clamp 31 and the second clamp 32 rotate with the same arc after being squeezed by the push rod 21. During the rotation of the first clamp 31 and the second clamp 32, the position of the hinge shaft 34 remains unchanged. The first clamp 31 and the second clamp 32 rotate around the hinge shaft 34 to separate or close. The length of the protruding opening 11 of the first clamp 31 and the second clamp 32 also remains unchanged. The two switch between the separated and closed states to achieve the clamping and release of the brush head 4.

[0093] like Figure 2 , Figure 3As shown, in the initial state, the lower ends of the first clamp 31 and the second clamp 32 are separated, and there is a certain gap between the upper ends of the first clamp 31 and the second clamp 32, which facilitates guiding the lower end of the push rod 21 downward into the gap between the first clamp 31 and the second clamp 32. As the push rod 21 moves downward, the lower ends of the first clamp 31 and the second clamp 32 gradually move closer together from the separated state until the lower ends of the first clamp 31 and the second clamp 32 are completely close together, aligned, and abut against each other, restricting the push rod 21 from moving further downward. This state can be called the closing state, i.e. Figure 4 and Figure 5 As shown. The gap between the upper ends of the first clamp 31 and the second clamp 32 is sufficient to guide the lower end of the push rod 21 into insertion.

[0094] The lower end of the push rod 21 is located between the first clamp 31 and the second clamp 32. In the direction perpendicular to its length, the push rod 21 is positioned between the first clamp 31 and the second clamp 32. There are two scenarios along the length of the push rod 21: First, in the initial state, the push rod 21 is already positioned between the first clamp 31 and the second clamp 32. During the transition from the initial state to the closing state, the depth of the push rod 21 between the first clamp 31 and the second clamp 32 gradually increases. Second, in the initial state, the push rod 21 is positioned above the first clamp 31 and the second clamp 32. During the transition from the initial state to the closing state, the push rod 21 first moves downwards from above the first clamp 31 and the second clamp 32 into the gap between them, and then, as the push rod 21 moves, its depth between the first clamp 31 and the second clamp 32 gradually increases.

[0095] The support structure of the first clamp 31 and the second clamp 32 can prevent the brush head 4 from detaching from the clamping component 3, and at the same time prevent the brush head 4 from wobbling on the clamping component 3, making it easier for the user to apply force to clean the toilet.

[0096] like Figures 6-8As shown, when using this disposable toilet brush, the user holds the housing 1 and presses the push rod 21, changing the relative position between the push rod 21 and the housing 1. The push rod 21 moves downward, and the upper ends of the first clamp 31 and the second clamp 32 gradually open, causing the lower ends of the first clamp 31 and the second clamp 32 to come together. After coming together, the first clamp 31 and the second clamp 32 can detach from or insert into the brush head 4. When the user removes the force applied to the push rod 21, the push rod 21 returns to its initial position under the elastic force of the first elastic element 22. The first clamp 31 and the second clamp 32 also return to their separated state under the elastic force of the second elastic element 33. The lower ends of the first clamp 31 and the second clamp 32 separate to form a larger support surface, which supports and clamps the brush head 4 through the support structure. This disposable toilet brush has a simple structure, is easy to use, and is simple to operate.

[0097] like Figure 2 , Figure 3 As shown, in some embodiments, the second elastic element 33 is located below the hinge shaft 34, with its two ends abutting between the first clamp 31 and the second clamp 32. The second elastic element 33 is also a compression spring. Positioned below the hinge shaft 34, in the initial state, the second elastic element 33 supports and separates the lower ends of the first clamp 31 and the second clamp 32, keeping them in an open state. When the push rod 21 pushes downwards, the lower ends of the first clamp 31 and the second clamp 32 move closer together, compressing the second elastic element 33 until the push rod 21 returns to its original position, maintaining the separation of the lower ends of the first clamp 31 and the second clamp 32. By placing the second elastic element 33 below the hinge shaft 34, a lever-type torque transmission is formed, making the clamp opening angle linearly related to the elastic deformation, significantly improving the accuracy of the opening and closing force control. In some embodiments, the second elastic member 33 may also be an annular elastic member sleeved on the first clamp 31 and the second clamp 32 and connecting the first clamp 31 and the second clamp 32 to the edge of the opening 11, or a plurality of elastic members arranged in an array along the circumference of the opening 11. These elastic members are stretched when the first clamp 31 and the second clamp 32 are closed, and after the push rod 21 is reset, these elastic members help the first clamp 31 and the second clamp 32 return to the separated state.

[0098] like Figure 2 , Figure 3As shown, in some more preferred embodiments, the length extension direction of the second elastic element 33 is perpendicular to the length extension direction of the hinge shaft 34. In this embodiment, assuming the second elastic element 33 is a compression spring, the length extension direction of the second elastic element 33 is the direction of its geometric central axis, and the length direction of the hinge shaft 34 is the direction of its central axis. The perpendicular arrangement of the second elastic element 33 and the hinge shaft 34 forms an orthogonal mechanical system, eliminating the wear of the hinge shaft 34 by lateral forces, and further reducing the stress on the hinge shaft 34 at the connection between the first clamp 31 and the second clamp 32, thus extending the service life of the clamping assembly 3.

[0099] In some embodiments, the first clamp 31 has a first mounting hole on the side facing the second clamp 32, and the second clamp 32 has a second mounting hole on the side facing the first clamp 31. The two ends of the second elastic member 33 are respectively fitted into the first mounting hole and the second mounting hole. The two parts of the second elastic member 33 can be respectively engaged in the first mounting hole and the second mounting hole, further preventing the second elastic member 33 from falling off. The nested hole installation achieves multi-dimensional positioning of the elastic member, maintaining its stable position even under severe vibration or drop scenarios, improving the product's impact resistance, and especially preventing the second elastic member 33 from falling off after a disposable toilet brush is dropped to the ground.

[0100] like Figures 2-5 As shown, in some embodiments, the lower end of the first clamp 31 is provided with a first support portion 311 folded away from the second clamp 32, and the lower end of the second clamp 32 is provided with a second support portion 321 folded away from the first clamp 31. The first support portion 311 and the second support portion 321 are symmetrically arranged. The outward side of the first support portion 311 and the second support portion 321 is an arc-shaped structure, so that the lower ends of the first clamp 31 and the second clamp 32 form a rounded shape after closing, which can be inserted into the brush head 4 from multiple directions without calibration, making operation convenient. At the same time, the first support portion 311 and the second support portion 321 can form two planar contact platforms, dispersing clamping stress, preventing damage to the thin-walled brush head 4, and also extending the service life of the clamping assembly 3.

[0101] like Figures 2-5 As shown, in some preferred embodiments, both the first support portion 311 and the second support portion 321 extend horizontally. That is, the lower ends of both the first clamp 31 and the second clamp 32 form an L-shaped structure, and the upper surfaces of the first support portion 311 and the second support portion 321 are located on the same horizontal plane to form a planar support, thereby improving the connection strength between the disposable toilet brush and the brush head 4.

[0102] like Figures 2-5As shown, in some embodiments, a first guide portion 212 and a second guide portion 213 are symmetrically arranged at the lower end of the push rod 21. The first guide portion 212 faces the first clamp 31, and the second guide portion 213 faces the second clamp 32. The first guide portion 212 and the second guide portion 213 facilitate the insertion of the push rod 21 between the first clamp 31 and the second clamp 32. When the push rod 21 is inserted between the first clamp 31 and the second clamp 32, it needs to resist the second elastic member 33, causing the second elastic member 33 to be compressed. By providing the first guide portion 212 and the second guide portion 213 at the lower end of the push rod 21, the push rod 21 can be smoothly inserted between the first clamp 31 and the second clamp 32, avoiding the push rod 21 from jamming with the first clamp 31 and the second clamp 32, or the force of the push rod 21 from deviating and concentrating on a certain clamp, effectively extending the service life of the clamping assembly 3 and the push rod 21.

[0103] In some more preferred embodiments, the first guide portion 212 includes a continuous first guide surface 2121 and a second guide surface 2122, and the second guide portion 213 includes a continuous third guide surface 2131 and a fourth guide surface 2132. Both the second guide surface 2122 and the fourth guide surface 2132 extend vertically, and the first guide surface 2121 and the third guide surface 2131 are inclined. The second guide surface 2122 and the fourth guide surface 2132 are sectional structures provided on the push rod 21. Taking a cylindrical push rod 21 as an example, the distance between the second guide surface 2122 and the fourth guide surface 2132 is smaller than the diameter of the push rod 21. The first guide surface 2121 faces the first chuck 31, and the third guide surface 2131 faces the second chuck 32. During the downward movement of the push rod 21, the first guide surface 2121 presses against the first chuck 31, causing it to rotate around the hinge axis 34, and the third guide surface 2131 presses against the second chuck 32, causing it to rotate around the hinge axis 34. As the push rod 21 continues to move, the first guide surface 2121 and the third guide surface 2131 continue to push the first chuck 31 and the second chuck 32 downwards. The second guide surface 2122 and the fourth guide surface 2132 do not contact each other. By setting the first guide surface 2121, the second guide surface 2122, the third guide surface 2131, and the fourth guide surface 2132, it is possible to ensure that the push rod 21 closes the lower ends of the first chuck 31 and the second chuck 32 only after a certain stroke.

[0104] like Figure 9As shown, in some embodiments, the push rod 21 includes a push rod body 214 and a push rod sleeve 215. The push rod body 214 has a guide groove 2141 extending along its length direction. The push rod sleeve 215 includes an upper limit ring 2151, a lower limit ring 2152 and a connecting rod 2153. The two ends of the connecting rod 2153 are respectively connected to the upper limit ring 2151 and the lower limit ring 2152.

[0105] The upper limit ring 2151 and the lower limit ring 2152 are both sleeved on the outside of the push rod body 214. The upper limit ring 2151 is provided with an upper guide piece 21511 adapted to the guide groove 2141, and the lower limit ring 2152 is provided with a lower guide piece 21521 adapted to the guide groove 2141.

[0106] The two ends of the first elastic member 22 abut against the lower limiting ring 2152 and the housing 1.

[0107] like Figure 2 , Figure 4 As shown, multiple stops 14 are arranged in an array along the length of the inner wall of the housing 1. At least two stops 14 are located above the upper limit ring 2151 and below the lower limit ring 2152. When the push rod 21 moves up and down inside the housing 1, the final position of the upper limit ring 2151 moving upward will not exceed the upper limit ring 2151, and the final position of the lower limit ring 2152 moving downward will not exceed the lower limit ring 2152. Through the cooperative action between the stops 14 and the upper limit ring 2151 and the lower limit ring 2152, the range of motion of the push rod 21 inside the housing 1 is further limited. The guide groove 2141 reduces the weight of the push rod body 214, and the upper limit ring 2151 sleeved on the push rod body 214 can be inserted into the guide groove 2141 through the upper guide piece 21511, and the lower limit ring 2152 can be inserted into the guide groove 2141 through the lower guide piece 21521. This prevents the push rod sleeve 215 from rotating relative to the push rod body 214 when the toilet brush is in use or dropped on the ground, further restricting the relative position of the lower end of the push rod 21 and the clamping assembly 3, achieving a perfect unity of axial movement and circumferential locking of the push assembly 2, and eliminating the risk of jamming.

[0108] like Figure 9 As shown, in some more preferred embodiments, there are two or more connecting rods 2153, which are arranged in a circumferential array outside the push rod body 214;

[0109] The inner wall of the housing 1 is adapted to guide the connecting rod 2153, and a gap is provided between the inner wall of the housing 1 and the push rod body 214.

[0110] When there are two connecting rods 2153, they are symmetrically arranged outside the push rod body 214. The connecting rods 2153 are staggered from the guide groove 2141 to prevent them from bending and being damaged when subjected to external impact. An inner wall groove adapted to the connecting rod 2153 is provided on the inner wall of the housing 1. The connecting rod 2153 fits into this groove, and during the axial movement of the push assembly 2, the inner wall groove guides the connecting rod 2153, ensuring smooth and unobstructed axial movement. The groove also prevents the push rod 21 from rotating circumferentially. A gap is provided between the inner wall of the housing 1 and the push rod body 214, which is generated in the inner wall groove during the axial movement of the push rod 21. This reduces the contact area between the push assembly 2 and the inner wall of the housing 1, thereby reducing friction and allowing for easy operation by the user.

[0111] like Figures 10-11 As shown, in some embodiments, the brush head 4 includes a support portion 41 and a cleaning portion 42, wherein the support portion 41 is connected to the upper surface of the cleaning portion 42;

[0112] The support part 41 has a support part through hole 411 in the middle, and the cleaning part 42 has a cleaning part through hole 421 or a cleaning part 42 groove corresponding to the position of the support part through hole 411.

[0113] The through hole 411 of the support portion allows the first clamp 31 and the second clamp 32 to pass through after they come together, and can prevent the first clamp 31 and the second clamp 32 from disengaging after they separate.

[0114] In this embodiment, the upper surface of the brush head 4 is relatively flat, and the clamping component 3 extends into the brush head 4 to clamp and fix it.

[0115] The support part 41 can be made of a relatively hard material to provide strong support and clamping strength, such as plastic. The support part 41 can be circular, square, elliptical, triangular, quadrilateral, or other unconventional structures. Similarly, the cleaning part 42 can also be circular, square, elliptical, triangular, quadrilateral, or other unconventional structures. Taking both the support part 41 and the cleaning part 42 as circular structures as an example, the diameter of the support part 41 is smaller than the diameter of the cleaning part 42. The support part 41 is centrally mounted on the cleaning part 42, so that the edge of the support part 41 and the edge of the cleaning part 42 maintain a certain distance, preventing the edge of the support part 41 from damaging the toilet glaze when the brush head 4 is cleaning the toilet. The thickness of the support portion 41 is less than the thickness of the cleaning portion 42, and its thickness generally does not exceed 5mm. The support portion 41 can be directly set on the upper surface of the cylindrical cleaning portion 42, or a mounting groove for the support portion 41 can be set on the upper surface of the cleaning portion 42 to fix the support portion 41 in the mounting groove, so that the upper surface of the support portion 41 does not exceed the upper surface of the cleaning portion 42, making it easy to push out or pull out a certain brush head 4 from the bottom or middle of a stack of brush heads 4. The shape of the through hole 411 of the support portion can be set as circular, or it can be designed as other shapes, as long as it can ensure that the clamping component 3 is not easily dislodged after being inserted into the through hole 411 of the support portion. The through hole 421 of the cleaning portion refers to the through hole structure set through the middle of the cleaning portion 42, and the groove of the cleaning portion 42 refers to the structure that is recessed downward from the upper surface of the cleaning portion 42 but does not penetrate to the bottom surface of the cleaning portion 42. The through hole 421 of the cleaning part or the groove of the cleaning part 42 should be larger than the through hole 411 of the support part, so that the first clamp 31 and the second clamp 32, after being brought together, can open in the through hole 421 of the cleaning part or the groove of the cleaning part 42 after passing through the through hole 411 of the support part, and restrict the first clamp 31 and the second clamp 32 from detaching upward from the through hole 411 of the support part after opening.

[0116] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
