Description

Technical Field

[0001] The invention relates to a tool for trimming hair, in particular to a washable hair clipper, belonging to the field of hairdressing equipment. Background Art

[0002] After using existing hair clippers, broken hair will more or less adhere to or accumulate on the inside or outside of the cutter head assembly. To prevent the broken hair from affecting the subsequent use of the cutter head assembly and reducing the trimming efficiency and effect of the cutter head assembly, the cutter head assembly is generally cleaned with a brush after use to remove the broken hair on the cutter head assembly. Because the trimming head is fixed or detachably fixed to one end of the cutter housing, the brush can only be used to clean the broken hair adhered or accumulated on the outside of the cutter head assembly, and the interior of the cutter head assembly can only be cleaned after the cutter head assembly is disassembled. For fixed-mounted cutter head assemblies, the interior of the cutter head assembly cannot be cleaned, seriously affecting the cleaning and performance of the cutter head assembly. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides a water-washable hair clipper that can be directly cleaned by rinsing with water. The hair clipper can clean the inside and outside of the cutter head assembly without disassembling the cutter head assembly. The hair clipper has a simple structure and is easy to operate, effectively ensuring the cleanliness of the hair clipper during use and improving the trimming efficiency of the hair clipper.

[0019] The embodiments of the present invention will be further described below with reference to the accompanying drawings:

[0020] like Figures 1 to 5As shown, the present invention is a washable hair clipper comprising a housing 1 and a cutting head assembly 2 mounted at one end of the housing 1. During actual production and assembly, the cutting head assembly 2 can be connected to the housing 1 using a removable snap-fit ​​mechanism or a fixed mechanism. Regardless of whether a removable or fixed connection is used, cleaning the interior of the cutting head assembly 2 presents a certain degree of difficulty. To facilitate cleaning of the hair clippers after use, a water-washing hole 3 is provided in the housing 1. A sliding sleeve 4 is disposed within the housing 1, which is horizontally movable along the inner wall of the housing 1. The sliding sleeve 4 is fixedly connected to a sliding button 5, which, when driven by an external force, causes the sliding sleeve 4 to close or open the water-washing hole 3. By providing a water washing hole 3 and a sliding sleeve 4 in the housing 1, when the hair clippers need to be cleaned, the sliding button 5 can be used to drive the sliding sleeve 4 to move horizontally along the inner wall of the housing 1 to open the water washing hole 3. At this time, the cleaning water pipe can be aligned with the water washing hole 3 or the water washing hole 3 can be placed under the faucet, and the pressure of the tap water can be used to clean the inside of the cutter head assembly 2 in the housing 1, removing the accumulated broken hair inside the cutter head assembly 2 or in the housing 1, ensuring the cleanliness of the interior of the hair clippers and effectively preventing the growth of bacteria or the accumulation of broken hair inside the hair clippers, which would affect the hair trimming effect and trimming efficiency of the cutter head assembly 2. After cleaning is completed, the sliding button 5 can be used again to drive the sliding sleeve 4 to move horizontally along the housing 1 to block the water washing hole 3, preventing debris from entering the interior of the housing 1 and affecting the hair trimming efficiency of the cutter head assembly 2.

[0021] To facilitate the sliding button 5 driving the sliding sleeve 4 to move horizontally along the housing 1 to open or close the water wash hole 3, a connection hole 41 is provided on the upper end surface of the sliding sleeve 4. The sliding button 5 includes a drive disk 51 and multiple claws 52 with barbs 53. The multiple claws 52 are inserted into the connection hole 41 and, using the barbs 53, securely connect the drive disk 51 to the sliding sleeve 4. Of course, a threaded connection can also be used to secure the sliding button 5 to the sliding sleeve 4. However, due to the relatively thin thickness of the sliding sleeve 4, such a threaded connection would easily cause the connection between the sliding button 5 and the sliding sleeve 4 to break. Therefore, the claw 52 structure is the preferred embodiment.

[0022] To improve the cleaning efficiency of the hair clippers, a water wash hole 3 is provided on the housing 1 near one end of the cutter head assembly 2. Since the movable blade of the cutter head assembly 2 needs to swing back and forth along the stationary blade, to prevent the movable blade from cutting along the stationary blade, conventional hair clippers are typically installed with a gap between the movable blade and the housing 1 after installation. Thus, when the water wash hole 3 is provided on the housing 1 near one end of the cutter head assembly 2, it functions as a water inlet, while the gap between the movable blade and the housing 1 functions as a drain. During cleaning, water enters the housing 1 through the water wash hole 3 and then exits through the gap between the movable blade and the housing 1, ensuring the cleanliness of the housing 1 and the inside of the cutter head assembly 2. This prevents excessive accumulation of broken hair inside the housing 1 or the inside of the cutter head assembly 2, which could lead to bacterial growth. Furthermore, this prevents the accumulation of broken hair inside the housing 1 or the inside of the cutter head assembly 2, which could affect the hair cutting efficiency of the cutter head assembly 2, thereby improving the cutting efficiency of the cutter head assembly 2. Of course, in actual use, the water washing hole 3 can be located anywhere on the housing 1, as long as the waterproof performance of the movement is guaranteed. For example, if a waterproof movement 7 is used, the water washing hole 3 can be located at the end of the housing 1 or in the middle of the housing 1, so that the entire interior of the hair clipper housing 1 can be cleaned. If the movement of the hair clipper is not waterproof, waterproof rings can be provided on one or both sides of the sliding sleeve 4 near the water washing hole 3 to achieve the same purpose. The specific structure to be used will depend on the waterproof performance of the hair clipper movement.

[0023] To facilitate cleaning of the hair clipper head assembly 2 and prevent broken hair from becoming lodged in the moving and stationary blades, two sets of water wash holes 3 are provided, located on opposing sides of the housing 1 near one end of the head assembly 2. With the water wash holes 3 positioned on opposing sides of the housing 1, during cleaning, clean water can enter the housing 1 through the gap between the head assembly 2 and the housing 1, or through one of the two sets of water wash holes 3. Broken hair flushed out by the water can be discharged through the other set of water wash holes 3. This prevents water carrying broken hair from being discharged from the head assembly 2 and minimizes the possibility of broken hair becoming lodged in the moving and stationary blades, effectively ensuring the trimming efficiency and effect of the head assembly 2 during use. The two sets of water wash holes 3 are positioned in the same direction as the mounting orientation of the head assembly 2, located on the front and back of the housing 1, respectively.

[0024] In order to enhance the overall aesthetics of the hair clippers and facilitate the horizontal displacement of the sleeve 4 along the housing 1 to open and close the water washing hole 3, a sliding groove 6 is provided on the housing 1, and a sliding button 5 is placed in the sliding groove 6 and fixedly connected to the sleeve 4. By providing the sliding groove 6 on the housing 1, one end of the sliding button 5 is snap-connected to the sleeve 4, and the other end is placed in the sliding groove 6. When the hair clippers need to be cleaned, the sliding button 5 is driven by the finger to slide along the sliding groove 6. At this time, the sleeve 4 can synchronously move horizontally along the inner wall of the housing 1 with the sliding button 5, thereby opening the water washing hole 3, which is conducive to cleaning the interior of the hair clippers housing 1 and the inner side of the blade assembly 2 with clean water. When cleaning is completed, the sliding button 5 is driven to slide in the opposite direction along the sliding groove 6, and the sliding sleeve 4 is synchronously displaced horizontally along the inner wall of the housing 1 to close the water washing hole 3, thereby preventing debris from entering the housing 1 through the water washing hole 3 during use and affecting the trimming performance of the blade assembly 2. During the actual production process, the height of the sliding button 5 is greater than the wall thickness of the shell 1, so that after the sliding button 5 is assembled into the sliding groove 6, the top of the sliding button 5 is slightly higher than the outer surface of the shell 1, which ensures the overall beauty of the hair clippers while facilitating the sliding operation of the sliding button 5 and improving the operating convenience of the sliding sleeve 4.

[0025] To improve the operating stability of the sliding sleeve 4 and prevent it from being displaced or deviated due to vibration during operation of the hair clippers, a waterproof mechanism 7 is provided within the housing 1. The sliding sleeve 4 is positioned outside the waterproof mechanism 7. The inner surface of the sliding sleeve 4 at least partially conforms to the outer surface of the waterproof mechanism 7, while the outer surface of the sliding sleeve 4 at least partially conforms to the inner surface of the housing 1. The sliding sleeve 4 can close and open the water washing hole 3 under the actuation of a sliding button 5. The entire or at least a portion of the inner surface of the sliding sleeve 4 conforms to the outer surface of the waterproof mechanism 7, which supports the sliding sleeve 4. Simultaneously, the entire or at least a portion of the outer surface of the sliding sleeve 4 conforms to the inner surface of the housing 1. The inner surface of the housing 1 and the outer surface of the waterproof mechanism 7 act as a restraint on the sliding sleeve 4, effectively preventing the sliding sleeve 4 from being displaced or deviated due to vibration during operation of the hair clippers. This ensures that the sliding sleeve 4 can quickly and smoothly open or close the water washing hole 3 under the actuation of the sliding button 5, thereby improving the operating stability of the sliding sleeve 4. In actual production, the inner cross-section of the sliding sleeve 4 matches the outer cross-section of the waterproof movement 7 , and the outer cross-section of the sliding sleeve 4 matches the inner cross-section of the housing 1 .

[0026] To prevent the sliding sleeve 4 from radially rolling or dislocating during the operation of the hair clippers, the outer side wall of the waterproof movement 7 is provided with a plurality of guide rails 8, and a corresponding guide groove 9 is provided on the side wall at one end of the sliding sleeve 4. The sliding sleeve 4 is placed outside the waterproof movement 7, and each guide groove 9 is limitedly matched with the guide rail 8. A plurality of guide rails 8 are provided on the opposite side walls of the waterproof movement 7, and a corresponding guide groove 9 is provided at the end of the sliding sleeve 4 near the cutter head assembly 2. During assembly, the guide grooves 9 of the sliding sleeve 4 can be matched with the guide rails 8 of the waterproof movement 7. When the sliding button 5 drives the sliding sleeve 4 to move horizontally, the matching of the guide rails 8 and the guide grooves 9 can effectively prevent the sliding sleeve 4 from radially rolling, ensure the working stability of the sliding sleeve 4, avoid the sliding button 5 from contacting the sliding groove 6 on the housing 1, and increase the resistance of the sliding sleeve 4 to horizontal sliding, and ensure the ease of operation of the sliding button 5 and the sliding sleeve 4. In actual production, the guide rails 8 and guide grooves 9 can be determined based on the shape of the waterproof movement 7. For example, if the waterproof movement 7 is square, two guide rails 8 can be provided on either side of the waterproof movement 7 to limit the horizontal displacement of the sliding sleeve 4. If the waterproof movement 7 is cylindrical, a single guide rail 8 can be provided on each of the opposing side walls of the waterproof movement 7 to effectively prevent radial rolling of the sliding sleeve 4 and ensure its operational stability.

[0027] To prevent the sliding sleeve 4 from excessively displacing along the inner surface of the housing 1, the waterproof movement 7 includes a drive seat 71 and a battery seat 72. The drive motor 73 is mounted within the drive seat 71, and the rechargeable battery 74 is mounted within the battery seat 72. The sliding sleeve 4 is positioned outside the drive seat 71, with its outer surface in contact with the inner wall of the housing 1. At least two edges 721 of the battery seat 72 are larger than the edges of the drive seat 71, so that when the sliding sleeve 4 is horizontally displaced along the drive seat 71 under the drive of the sliding button, the end face of the sliding sleeve 4 and the edge 721 of the battery seat 72 are limited and in contact. The edges 721 of at least two sides of the battery seat 72 are larger than the outer edges of the drive seat. When the sliding sleeve 4 is positioned outside the drive seat 71 and the sliding button 5 drives the sliding sleeve 4 to move horizontally along the inner surface of the housing 1 to open the water washing hole 3, the outer edge 721 of the battery seat 72 can restrain the end face of the sliding sleeve 4, effectively preventing excessive displacement of the sliding sleeve 4, avoiding breakage at the connection between the sliding button 5 and the sliding sleeve 4, and ensuring the safety of the sliding sleeve 4. In actual production, the two opposite side edges 721 of the battery seat 72 are larger than the outer edge of the driving seat 71 to limit the displacement of the sliding sleeve 4.

[0028] Since the housing and the sleeve 4 may have some processing errors during the production process, to prevent the sleeve 4 from automatically blocking the water washing hole 3 when cleaning the interior of the housing 1 or the inner side of the cutter head assembly 2, a limit plate 42 is provided at one end of the sleeve 4. The limit plate 42 is thinner than the thickness of the sleeve 4, and an open slot 43 is provided at the end of the limit plate 42. When the sliding button is driven, the open slot 43 of the sleeve 4 can engage with the limit block 45, thereby self-locking the sleeve 4 within the housing 1. By adding the limit plate 42 to the end of the sleeve 4 relative to the cutter head assembly 2 and providing the open slot 43 on the limit plate 42, when the sliding button 5 drives the sleeve 4 to move horizontally along the inner surface of the housing 1, the open slot 43 on the limit plate 42 can engage with the limit block 45, thereby achieving self-locking of the sleeve 4, effectively preventing the sleeve 4 from automatically blocking the water washing hole 3 due to processing errors or fitting clearance. When cleaning is complete, the sliding button 5 drives the sliding sleeve 4 to disengage the limiting plate 42 from the limiting block 45, thereby facilitating the sliding sleeve 4 to seal the water washing hole 3. To reduce frictional resistance between the sliding sleeve 4 and the housing 1, the limiting plate 42 is thinner than the thickness of the sliding sleeve 4, creating a gap between the limiting plate 42 and the inner surface of the housing 1. This prevents the limiting plate 42 from directly contacting the inner surface of the housing 1 when the sliding button drives the sliding sleeve 4 to move horizontally along the inner surface of the housing 1. This minimizes frictional resistance between the sliding sleeve 4 and the housing 1, reduces the operating torque of the sliding button 5, and facilitates the sliding sleeve 4 to open or seal the water washing hole 3. During the actual production process, a hook 44 is provided at the opening of the opening slot 43 of the limit plate 42, and the cross-section of the limit block 45 is olive-shaped with pointed ends and a large middle. When the sliding sleeve 4 moves with the sliding button 5 to open the water washing hole 3, the hook 44 at the opening of the opening slot 43 on the limit plate 42 can be directly hooked on the outer side surface of the limit block 45 to make the limit plate 42 and the limit block 45 snap-connected. In this way, the sliding sleeve 4 can form a self-locking function, effectively preventing the sliding sleeve 4 from automatically moving and blocking the water washing hole 3 due to processing errors or gaps, thereby affecting the cleaning operation.

[0029] To ensure the stability of the self-locking mechanism of the sliding sleeve 4 after it opens the water washing hole 3, a stopper 45 is provided on the inner sidewall of the housing 1. By placing the stopper 45 on the inner sidewall of the housing 1, when the sliding sleeve 4 opens the water washing hole 3 under the action of the sliding button 5, the stopper plate 42 at one end of the sliding sleeve 4 can be displaced accordingly, causing the opening groove 43 to engage with the stopper, thereby achieving the self-locking mechanism of the sliding sleeve 4. In actual production, the stopper 45 can be integrally connected to the housing 1 through a split structure, or the housing 1 can be a split structure, with the stopper 45 integrally injection-molded with the upper housing 1, thereby achieving the same production and assembly of the stopper 45.

[0030] To ensure the stability of the self-locking of the sliding sleeve 4 after opening the water-washing hole 3, a limit block 45 is provided on the waterproof mechanism 7. The limit block 45 is provided on the battery holder 72 of the waterproof mechanism 7 and can be integrally injection-molded with the battery holder 72 during processing. In this way, the housing 1 can be integrally injection-molded, enabling the internal and external water washing of the entire hair clipper, thereby improving the waterproof performance of the entire hair clipper.

[0031] The above embodiments should not be regarded as limiting the present invention, but any improvements based on the spirit of the present invention should be within the scope of protection of the present invention.
