Description

Technical Field

[0001] This utility model relates to the field of cleaning tools, specifically to a hair removal brush with a replaceable wiping pad, which is particularly suitable for pet hair removal scenarios. Background Technology

[0002] In the cleaning tool industry, lint removers with wiping pads are widely used for cleaning pet hair. Users frequently replace the wiping pads based on wear and tear and usage scenarios. Furthermore, the wiping pad needs to be securely fixed in place to prevent it from loosening when the user applies significant force during hair removal. Therefore, a structure that is both easy to install and remove, and robust and stable, is needed to secure the wiping pad. However, existing technologies either fail to provide a stable hold or are inconvenient to install and remove, thus failing to meet the needs of pet hair removal.

[0003] Existing technology ZL201320156420.X designs a glass scraper that uses the elastic force of a spring to hold the upper and lower clamping arms, which are hinged together, so that the scraper head can clamp the rubber strip; manually compressing the spring opens the upper and lower clamping arms, allowing for quick assembly and disassembly of the rubber strip. However, it has the following drawbacks:

[0004] 1) Poor clamping stability: The clamping force depends on the spring force. If the downward pressure exceeds the spring force during use, the rubber strip will shift or fall off.

[0005] 2) High assembly difficulty: The spring is sleeved on the shaft pin and set between the upper clamping arm and the lower clamping arm. During assembly, the four components of the upper clamping arm, lower clamping arm, shaft pin and spring need to be fixed to each other at the same time. Usually, it is necessary to use tooling to fix 2-3 of the components before installing the remaining components to complete the assembly.

[0006] 3) Poor durability: The spring is prone to rust, which leads to a decrease in elasticity.

[0007] Existing technology ZL201220724595.1 designs a replaceable scouring pad cleaning brush. The scouring pad is secured by a hook on the lower brush plate engaging with a slot on the upper brush plate; pressing the hook disengages it from the slot, opening the upper and lower brush plates to allow for scouring pad replacement. However, it has the following drawbacks:

[0008] 1) High difficulty in replacement: The size of the hook is limited by the size of the snap-fit ​​slot. When pressing the hook, the finger pressure area is small, making it difficult to press and disassemble. Utility Model Content

[0009] 1. Technical problem to be solved by the utility model

[0010] To address the problems of insufficient clamping force, easy loosening of wiping pads, high assembly difficulty, poor durability, or high replacement difficulty in existing quick-release structures, this utility model provides a lint removal brush that can be easily disassembled and assembled without tools and operated with one hand, while also firmly fixing the wiping pad.

[0011] 2. Technical Solution

[0012] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0013] Firstly, a lint-removing brush with a replaceable wiping pad includes a handle and a brush head.

[0014] The brush head includes an upper clamping plate and a lower clamping plate that are hinged together by a clamping plate pivot or connected by a spring sheet, and a U-shaped fixing groove is formed between the two.

[0015] The lower clamping plate is provided with several connecting plates along the thickness direction of the brush head. The connecting plates are hinged with L-shaped lever structure pressure buckles along the length direction of the brush head. The short arm end of the lever structure forms a limiting rib, which controls the opening and closing of the upper clamping plate.

[0016] The detachable clamp in the U-shaped fixing groove holds the wiping pad, with its fixing part inserted into the fixing groove and the wiping part extending to the outside to perform cleaning operations;

[0017] The pressure buckle has a locked position and an open position: in the locked position, the limiting rib presses against the upper clamping plate to form a clamping state; in the open position, the limiting rib releases the constraint on the upper clamping plate, allowing the wiping pad to be removed along the width direction of the brush head.

[0018] Furthermore, when the wiping pad fixing part is inserted into the U-shaped fixing groove and the pressure buckle is in the locked position, the pressure buckle, the upper clamping plate, the lower clamping plate, and the wiping pad are in an interference fit state.

[0019] Furthermore, the maximum interference position of the interference fit is located between the locking position and the opening position of the pressure buckle.

[0020] Furthermore, the contact surfaces of the fixing part and / or the U-shaped fixing groove are provided with anti-slip texture.

[0021] Optionally, the upper side of the upper clamping plate and / or the lower side of the lower clamping plate are provided with auxiliary cleaning parts, the material of which is selected from at least one of sponge, polyester velvet cloth, tufted brush, soft rubber bristles, metal scraper, and tear-paper lint roller.

[0022] As an optional technical solution of the first aspect, the wiping parts of the wiping pad are symmetrically arranged on both sides of the fixing part to form a double-sided wiping structure that can be flipped 180° and reused.

[0023] Furthermore, clamping planes parallel to the length direction are provided on both sides of the opening of the U-shaped fixing groove, and the clamping plate pivot of the upper clamping plate, the connecting plate of the lower clamping plate, and the buckle pivot of the pressure buckle are all located at the bottom of the U-shaped fixing groove.

[0024] Optionally, the protrusion height n of the limiting rib satisfies the following conditions: when the wiping part is made of silicone, TPE, TPR, TPU or PVC, n≥1mm; when the wiping part is made of sponge, n≥3mm.

[0025] Optionally, the wiping part is provided with at least one type of scraping tooth selected from serrated scraping teeth, columnar scraping teeth, or conical scraping teeth.

[0026] As another alternative technical solution of the first aspect, the gripping part is provided with a hollow dust suction channel, one end of which forms a dust suction port located on the lower side of the lower clamping plate, and the other end is provided with a vacuum cleaner interface.

[0027] 3. Beneficial effects

[0028] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0029] Improved disassembly and assembly efficiency: The wiping pad can be replaced with a single-handed rotating pressure buckle without the need for tools, taking ≤10 seconds;

[0030] Enhanced structural reliability: 1) The anti-rotation design of the pressure buckle improves clamping stability along the thickness direction of the brush head; 2) The anti-slip texture matches the clamping plane, improving clamping stability along the width and length directions of the brush head.

[0031] Excellent functional expandability: Through modular design, it is compatible with vacuuming and reusable functions. Attached Figure Description

They are not intended to limit the scope of the invention and therefore have no substantial technical significance.

Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention's implementation.

[0048] Implementation Method 1 (Basic Structure)

[0049] like Figure 1-3 As shown, this embodiment provides a lint remover brush with a replaceable wiping pad. The lint remover brush is T-shaped and consists of a handle 100 and a brush head 200. The handle 100 has a comfortable, rounded grip and is integrally injection molded with a component of the brush head 200. The brush head 200 has a rectangular plate-like structure, with its short side defined as the width direction (X-direction) and its long side as the length direction (Y-direction).

[0050] As an improvement, one end of the grip 100 is detachably assembled with the brush head 200 via a threaded connection or snap-fit ​​connection to reduce packaging size and save warehousing and logistics costs.

[0051] like Figure 1 , Figure 2 As shown, the brush head 200 includes an upper clamping plate 210 and a lower clamping plate 220, which are hinged together by a clamping plate pivot 211 to form an opening and closing structure. The axis of the clamping plate pivot 211 is parallel to the Y direction. A U-shaped fixing groove 230 is formed between the upper clamping plate 210 and the lower clamping plate 220. The opening of the U-shaped fixing groove 230 is provided with clamping planes 231 with a width of 15mm on the upper and lower sides. The distance a between the upper and lower clamping planes 231 is 5mm. One or both sides of the upper and lower clamping planes 231 are raised with a number of parallel anti-slip textures 311. The upper anti-slip texture is b1 high, the lower anti-slip texture is b2 high, and the total height b = b1 + b2, where b ∈ [0.8mm, 1.2mm].

[0052] As an alternative, the upper clamping plate 210 and the lower clamping plate 220 are connected by a U-shaped spring sheet 212. The spring sheet 212 can be made of stainless steel with a thickness of 0.3-0.6mm or plastic with a thickness of 1-1.5mm. The spring sheet 212 is integrally injection molded with the upper clamping plate 210 and the lower clamping plate 220, or fixed by riveting.

[0053] Two sets of connecting plates 221 are spaced apart along the Y direction on the upper surface of the lower clamping plate 220. Each set of connecting plates 221 has a 2mm diameter shaft hole at its top. The corresponding upper clamping plate 210 has an elongated through hole corresponding to the position of the connecting plate 221, allowing the connecting plate 221 to extend upward through the through hole. The pressure buckle 240 is hinged to the connecting plate 221 via a 2mm diameter buckle pivot 242, the axis of which is parallel to the Y direction.

[0054] The main body of the pressure buckle 240 is an L-shaped lever structure. The axis of the buckle shaft 242 is the fulcrum of the L-shaped lever structure, and the short arm end of the L-shaped lever structure forms a limiting rib 241. The end of the limiting rib 241 protrudes 1.2mm from the other circumferential surfaces of the buckle shaft 242. When the pressure buckle 240 is rotated to the open position (e.g.) Figure 3When the limiting rib 241 moves away from the upper clamping plate 210, the constraint on the upper clamping plate 210 is released, and the lower clamping plate 220 opens under its own weight, increasing the distance 'a' between the upper and lower clamping planes 231 at the opening of the U-shaped fixing groove from 5mm to 6.7mm. When the pressure buckle 240 rotates 135° to the locking position (e.g. Figure 2 The limiting rib 241 presses down against the upper clamping plate 210, while the buckling shaft 242 pulls the lower clamping plate upward through the connecting plate 221, so that the distance a between the upper and lower clamping planes 231 returns to the initial 5mm.

[0055] The wiping pad 300 is injection molded from TPR soft rubber material and is in the form of a flat sheet or a gently curved sheet. The thickness c of the fixing part 310 is 4.5mm, and the thickness of the bottom surface of the wiping part 320 gradually decreases from the side near the fixing part to the side away from the fixing part. The upper surface of the wiping part 320 is provided with several rows of sawtooth scraping teeth 321 (tooth height 2-5mm, tooth spacing 1.2mm, tooth row center distance 4mm), and the lower surface of the wiping part 320 is provided with staggered conical scraping teeth 322 (tooth height 1.5-2.5mm, tooth spacing 2.5mm-3.5mm).

[0056] When replacing or installing the wiping pad 300, firstly, rotate the pressure buckle 240 to the open position. The lower clamping plate 220 opens under its own weight, and the distance a between the upper and lower clamping planes 231 at the opening of the U-shaped fixing groove increases from 5mm to 6.7mm. At this time, the distance a between the upper and lower clamping planes 231, the total height b of the upper and lower anti-slip textures, and the thickness c of the fixing part satisfy the relationship ab>c, allowing the wiping pad 300 to move in the X direction. Secondly, pull out the old wiping pad in the X direction, insert the new wiping pad, and rotate the pressure buckle 240 to the locked position to complete the replacement. When locked, under the pressure of the limiting rib 241, the upper clamping plate 210 and the lower clamping plate 220 clamp the fixing part 310. The pressure buckle 240, the upper clamping plate 210, the lower clamping plate 220, and the wiping pad 300 are in an interference fit state. At this time, the distance a between the upper and lower clamping planes 231, the total height b of the upper anti-slip texture + the lower anti-slip texture, and the thickness c of the fixing part satisfy the relationship ab < c. The anti-slip texture 311 and the fixing part 310 are in an interference fit state, so that the wiping pad 300 is firmly fixed in the X and Y directions.

[0057] As an improvement, the pressure buckle incorporates an anti-rotation design. Specifically, on one hand, the upper clamping plate 210 has a buckle support plane, and the pressure buckle 240 has another plane, which serves as the locking contact surface. When the pressure buckle 240 is in the locked position, the locking contact surface and the buckle support surface are in contact, allowing the pressure buckle to remain stably in the locked position. On the other hand, there is a maximum interference position (e.g., between the locked position and the open position) between the two positions. Figure 4When in the maximum interference position, the short arm end of the L-shaped lever structure of the pressure buckle 240 presses down the buckle support plane to its maximum distance. At this time, the distance a between the upper and lower clamping planes 231 is minimized, and the interference engagement between the anti-slip texture 311 of the upper and lower clamping plates and the fixing part 310 of the wiping pad 300 is maximized. The interference between the pressure buckle 240, the upper clamping plate 210, the lower clamping plate 220, and the wiping pad 300 is maximized. Since the interference at the maximum interference position is greater than that at the locking position, when the pressure buckle 240 is between the locking position and the maximum interference position, the pressure buckle will automatically return to the locking position. Thus, the pressure buckle 240 can be stably maintained in the locking position, ensuring that the upper and lower clamping plates remain stably clamped even when the lint remover is bumped, shaken, or the wiping pad 300 is subjected to a force in the thickness direction. As an additional benefit, this anti-rotation design improves the user experience of the pressure buckle 240. When the user inserts the wiping pad 300 and rotates the pressure buckle 240 from the open position to the maximum interference position, the pressure buckle 240 automatically rotates to the locked position, clearly giving the user the feeling that it has been rotated into place.

[0058] As an extended implementation, the protrusion height n of the limiting rib 241 can be set to different values ​​according to the material deformation properties of the wiping pad 300. The more easily the material deforms, the greater the required height n. Specifically, when the material of the wiping pad 300 is silicone / TPE / TPR / TPU with a Shore hardness greater than 60, n∈[1mm, 1.5mm); when the material of the wiping pad 300 is silicone or TPR with a Shore hardness less than 60, n∈[1.5mm, 3mm); when the wiping pad 300 is made of sponge material, n≥3mm. The sponge material includes, but is not limited to, sandblasted sponge, polyester sponge, wood pulp sponge, and melamine resin sponge. Correspondingly, when the pressure buckle is in the locked position, the interference engagement depth between the anti-slip texture 311 of the upper and lower clamping plates and the fixing part 310 of the wiping plate 300 is about 0.5mm, about 1.75mm, and more than 3mm, respectively. This ensures the reliability of clamping while preventing the material from being excessively compressed beyond the strength of the upper and lower clamping plates, which could lead to plastic or rigid deformation of the upper and lower clamping plates.

[0059] As another extended implementation, an auxiliary cleaning section 250 is provided on the upper side of the upper clamping plate 210 and / or the lower side of the lower clamping plate 220. The material of this section is selected from at least one of the following: sponge, polyester flannel, flocked brush, soft rubber bristles, metal scraper, and tear-paper lint roller. For example, a metal scraper is provided on the upper side of the upper clamping plate 210, and polyester flannel is provided on the lower side of the lower clamping plate 220. Another example is that soft rubber bristles are provided at the front of the lower side of the lower clamping plate 220, and a tear-paper lint roller is provided at the rear. This structure can handle various cleaning scenarios, and actual tests show that it improves pet hair removal efficiency by 40% in complex scenarios such as cat trees and cat enclosures.

[0060] Implementation Method Two (Integrated Vacuuming Function)

[0061] Combination Figure 5-7 As shown, in this embodiment, a suction channel 110 is integrated below the grip 100 and the lower clamping plate. The suction channel 110 is divided into a straight pipe section and a slit section. The straight pipe section has an inner diameter of 25mm and its end opening forms a vacuum cleaner interface 112. The slit section is located on the lower surface of the lower clamping plate 220, and its end opening forms a suction port 111, approximately 1mm from the working end face of the wiping section 320. The vacuum cleaner interface 112 can be installed by a straight insertion method to fit tightly with the dust collection chamber interface of a small handheld vacuum cleaner, or it can use a standard 35mm quick-release connector to adapt to mainstream vacuum cleaner hoses.

[0062] During operation, the suction airflow passes through the suction port 111 at a speed of 8-12 m / s, creating a negative pressure zone in front of the wiping section 320. Testing has shown that this structure can simultaneously remove over 85% of dust and debris, while effectively solving the problem of static electricity and lint caused by friction between plastic and fur, thus improving the user experience and cleaning efficiency.

[0063] like Figure 6-7 As shown, the upper clamping plate 210 and the lower clamping plate 220 are connected by an arc-shaped spring piece 212, which is integrally injection molded with the upper clamping plate 210 and the lower clamping plate 220. When the pressure buckle 240 is rotated to the locking position (as shown), Figure 7 When the pressure buckle 240 is in the open position, the limiting rib 241 of the pressure buckle 240 presses against the upper clamping plate 210, causing the upper clamping plate 210 to move downward under force and increasing the bending deformation of the arc-shaped spring piece 212. The distance between the upper clamping plate 210 and the lower clamping plate 220 decreases to less than the thickness of the wiping pad fixing part 310, forming a state of firmly holding the wiping pad 300. When the pressure buckle 240 is rotated to the open position, the limiting rib 241 releases the restriction on the upper clamping plate 210, and the upper clamping plate 210 springs upward under the elastic force of the arc-shaped spring piece 212, opening the U-shaped fixing groove and allowing the wiping pad 300 to move in the X direction. The arc-shaped spring piece can be a metal spring piece or a plastic spring piece made of PC or ABS material with high strength and good elasticity.

[0064] Implementation Method 3 (Double-sided Reusable Structure)

[0065] Combination Figure 8-10 As shown, this embodiment employs a dual-wiping section design. The wiping sections 320 of the wiping pad 300 are symmetrically arranged on both sides of the fixing section 310. The upper and lower wiping surfaces of the wiping section 320 are respectively molded with scraping teeth of different functions: the first wiping surface has 4 rows of sawtooth scraping teeth 321 (tooth height 2-3mm, tooth spacing 1.2mm, tooth row center distance 4mm), and the second wiping surface has 4 rows of conical scraping teeth 322 (tooth height 2-3mm, tooth spacing 2-3mm, row spacing 4mm). The surface of the fixing section 310 has several parallel anti-slip textures 311 raised on it.

[0066] The opening of the U-shaped fixing groove 230 is tapered, and it has a clamping plane 321 with a width of 5mm. The depth of the U-shaped fixing groove 230 is increased to 31mm, with space reserved inside for accommodating the wiping part 320 and the scraping teeth. The hinge-related structures such as the clamping plate pivot 211, the snap-fit ​​pivot 242, and the connecting plate 221 are concentrated at the bottom of the U-shaped fixing groove 230. Several positioning ribs are provided on the upper and lower side walls of the U-shaped fixing groove 230 to ensure accurate positioning of the wiping part 320 after flipping.

[0067] When the wiping part on one side is worn, first rotate the pressure buckle 240 to the open position (e.g. Figure 10 Release the constraint of the limiting rib 241 of the pressure buckle 240 on the upper clamping plate 210, manually lift the upper clamping plate 210 to open the opening of the U-shaped fixing groove 230, pull out the wiping pad along the X direction, rotate it 180° and reinsert it. Then fasten the upper clamping plate 210, and rotate the pressure buckle 240 to the locked position (e.g., Figure 9 This causes the limiting rib 241 to press against the upper clamping plate 210. At this point, the original inner wiping section becomes active, enabling double-sided reuse. Laboratory tests have shown that this design can extend the service life of the wiping pad by 100% while increasing the total weight by approximately 40-60%.

[0068] The above implementation methods can be implemented independently, and different implementation methods for different components can also be combined with each other without specific limitations.

[0069] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
