Description

Technical Field

[0001] This application relates to the field of hair clippers, and more particularly to a hair clipper that is easy to clean. Background Technology

[0002] Easy-to-clean pomade clippers, also known as pomade clippers, consist of a blade holder and a movable blade, both of which are equipped with serrations. When in use, pushing the clippers moves the blade, which, along with the serrations on the blade holder, cuts the hair to achieve a trimming effect.

[0003] In related technologies, the blade holder includes a housing and a fixed blade, with a movable blade head movably mounted on the blade holder. The housing has an inner cavity in which a motor is installed. The movable blade head includes a movable blade and a transmission structure. The motor drives the movable blade to move through the transmission structure. Therefore, the end of the housing near the fixed blade has an opening for the movable blade to pass through. Because the movable blade head is movable, during use, the cut hair clippings easily fall into the inner cavity of the housing through the opening, making cleaning inconvenient.

[0004] To address these issues, related technologies typically employ methods such as minimizing the gap between the moving blade and the housing, or adding a sealing structure between the housing and the moving blade. However, it is still impossible to completely prevent a small amount of hair from falling into the inner cavity of the housing. Utility Model Content

[0005] To improve the ease of initial feeding of the woven fabric and inner membrane, this application provides an easy-to-clean oil-tipped scissors.

[0006] This application provides a convenient and easy-to-clean hair clipper, which adopts the following technical solution:

[0007] A convenient-to-clean hair clipper includes a housing, the housing including a mounting shell, a fixed blade fixedly mounted on the mounting shell, the housing having an opening near the end of the fixed blade and an inner cavity, a movable blade head movably mounted in the inner cavity of the housing, the movable blade head including a movable blade extending out of the inner cavity of the housing, the housing also including a detachable shell detachably connected to the mounting shell, the detachable shell being located on the side of the mounting shell near the movable blade.

[0008] Considering the inability to completely prevent hair fragments from entering the inner cavity of the housing, the applicant designed this application from the perspective of easy cleaning. The housing is designed as a detachable mounting shell and a disassembly shell (with the disassembly shell located near the working end of the blade), allowing users to easily disassemble the disassembly shell to directly expose the inner cavity of the housing and move the blade head for cleaning the inner cavity of the mounting shell (which can be cleaned by water flushing). This fundamentally solves the problem mentioned in the background art of the difficulty in cleaning hair fragments that enter the inner cavity through the end opening of the housing. Users can quickly and thoroughly remove accumulated hair fragments from the inner cavity without complicated tools or disassembling the entire device, greatly improving the maintainability and hygiene of the equipment.

[0009] Optionally, the disassembly shell has a through-hole for mounting, and a transparent observation window can be detachably connected to the mounting hole.

[0010] By adopting the above technical solution, a detachable transparent observation window is set on the disassembly shell, allowing users to directly observe the hair accumulation inside the shell (especially the inner cavity and the vicinity of the moving blade head) in real time without disassembling the entire disassembly shell. This makes it easier for users to determine when cleaning operations are needed, improving the product's ease of use and the timeliness of maintenance.

[0011] Optionally, the disassembly shell has a locking block, and the inner wall of the mounting shell has a slot for the locking block to be inserted. The disassembly shell and the mounting shell are connected by the locking block and the slot.

[0012] By adopting the above technical solution, the disassembly shell and the mounting shell are detachably connected through the snap-fit ​​connection of the card block and the card slot. This provides a simple and quick disassembly and installation method (usually only requiring pressing or prying) without the need for additional fasteners (such as screws), which significantly improves the efficiency of user disassembly, cleaning and reassembly. At the same time, this connection method itself also has a certain degree of connection reliability.

[0013] Optionally, a positioning block is formed on the surface of the disassembly shell near the mounting shell, and a positioning groove is provided on the surface of the mounting shell near the disassembly shell for the positioning block to be inserted and rotated.

[0014] By adopting the above technical solution, a more stable positioning and connection mechanism that works in conjunction with the snap-fit ​​connection is provided. After the positioning block is inserted into the positioning slot, it is locked by rotation (e.g., 90 degrees), which can withstand greater separation or shearing forces, effectively preventing the disassembly shell from accidentally detaching when subjected to external forces in a specific direction. This significantly improves the connection strength and reliability of the disassembly shell in the installed state, and is especially suitable for occasions requiring a more secure connection.

[0015] Optionally, a hand-held block is formed on the surface of the disassembly shell, and the hand-held block extends along the extension direction of the locking block.

[0016] By adopting the above technical solution, a dedicated and easy-to-apply gripping point is provided for users when disassembling or installing the case. This raised or thickened grip increases the contact area and friction of the user's fingers. When disassembling the case, the user can squeeze the grip to push the locking block out of the slot. When installing the case, the user can push against the grip, making the operation (especially when a certain amount of force is required to press and unlock) more convenient, stable, and effortless, significantly improving the convenience of human-computer interaction and the comfort of operation.

[0017] Optionally, an inclined guide surface is formed on the inner wall surface of the mounting shell near the disassembly shell and / or on the end of the card block, the guide surface being used to guide the card block to deform and squeeze into the card slot.

[0018] By adopting the above technical solution, when the user installs or removes the shell, the guide surface can effectively guide the locking block to undergo elastic deformation (such as bending of plastic parts) when it contacts the edge of the shell or the edge of the slot, thus making it easier to slide into the slot. This significantly reduces the difficulty of alignment and force application when installing or removing the shell, making the buckle connection process smoother and less strenuous.

[0019] Optionally, an unlocking arc surface is formed on the card block, and a guiding arc surface is formed on the groove wall of the card slot. The unlocking arc surface is bent toward the direction close to the guiding arc surface, and the guiding arc surface is bent toward the direction away from the unlocking arc surface. The unlocking arc surface is used to abut against the guiding arc surface.

[0020] By adopting the above technical solution, when the user needs to disassemble the shell, after applying a force in a specific direction, the interaction between the unlocking arc surface and the guiding arc surface can more effectively guide the card block to deform, making it easier to detach from the slot, greatly reducing the difficulty of disassembly and the required force, and improving the user experience; at the same time, when installed, this arc surface cooperation can also provide a certain degree of contact stability.

[0021] Optionally, a transition plane is formed between the guide surface and the guide arc surface, and the transition plane is used to abut against the disassembly shell.

[0022] By adopting the above technical solution, the transition plane can form a surface contact support with the disassembly shell (or its corresponding structure) after the disassembly shell is installed in place, which plays a positioning and limiting role, effectively preventing the disassembly shell from shaking or accidentally loosening due to vibration or slight external force during normal use, and enhancing the structural stability and reliability of the snap-fit ​​connection in the closed state.

[0023] Optionally, a plurality of limiting blocks are formed on the surface of the disassembly shell near the mounting shell, and a plurality of limiting grooves are provided on the surface of the mounting shell near the disassembly shell for different limiting blocks to be inserted.

[0024] By adopting the above technical solution, the structure of inserting multiple limiting blocks into the limiting groove can accurately guide the installation position of the disassembly shell relative to the mounting shell, ensuring that the two are quickly and accurately positioned and aligned, effectively preventing misalignment or displacement during installation; at the same time, this multi-point limiting structure can also enhance the disassembly shell's ability to resist lateral or torsional external forces after installation, preventing it from shifting or loosening due to force during use, further improving the convenience of assembly and the overall stability of the connection.

[0025] Optionally, the inner cavity of the mounting housing is provided with a drive source for driving the moving cutter head to move. The mounting housing includes two detachably connected flap housings. The detachable housing is detachably connected to one of the flap housings. A sealing element is provided on the surface of the flap housing near the other flap housing. The sealing element is used to press against the drive source.

[0026] By adopting the above technical solution, the seal between the valve shells effectively prevents liquids (such as cleaning fluids and sweat) or small hairs from entering the core area inside the equipment (such as the motor compartment) through the valve shell joints, significantly improving the overall protection level and service life of the equipment.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The housing is designed as a detachable mounting shell and a disassembly shell, allowing users to easily disassemble the disassembly shell to clean the inner cavity of the mounting shell, thus improving the maintainability and hygiene of the equipment.

[0029] 2. Allows users to view the accumulation of hair inside the casing in real time through the observation window, making it easier for users to determine when cleaning is needed, thus improving the product's ease of use and the timeliness of maintenance;

[0030] 3. The handheld block provides users with a dedicated and easy-to-grip point when disassembling or installing the shell, making the operation more convenient, stable and effortless, and significantly improving the convenience of human-computer interaction and the comfort of operation.

[0038] The following combination Figures 1-6 This application will be described in further detail.

[0039] This application discloses a convenient and easy-to-clean hair clipper. (See also...) Figure 1 The easy-to-clean hair clipper includes a housing 1, which includes a mounting shell 11 on which a fixed blade 2 is fixedly mounted. The housing 1 has an opening at its end near the fixed blade 2 and an inner cavity. A movable blade head 3 is movably mounted within the inner cavity of the housing 1, and the movable blade head 3 includes a movable blade 31 extending through the inner cavity of the housing 1. The housing 1 also includes a detachable shell 12 detachably connected to the mounting shell 11, located on the side of the mounting shell 11 near the movable blade 31.

[0040] Reference Figure 1 The mounting housing 11 includes two petal housings 117, which are detachably connected by a snap-fit ​​and bolt assembly. The length direction of the housing 1 is defined as vertical, and the two petal housings 117 are arranged in a front-to-back direction. The petal housing 117 located at the front is the front petal housing 118, and the disassembly housing 12 is detachably connected to the front petal housing 118. There is a gap between the disassembly housing 12 and the moving blade 31. The disassembly housing 12 and the two petal housings 117 together enclose the inner cavity of the housing 1.

[0041] Reference Figure 2 A positioning block 123 is integrally formed on the lower surface of the disassembly shell 12, and a positioning groove 112 for the positioning block 123 to be inserted is formed on the surface of the front flap shell 118 near the disassembly shell 12. The size of the positioning groove 112 is larger than the size of the positioning block 123, and the positioning block 123 can rotate within the positioning groove 112 after being inserted into it.

[0042] Reference Figure 2 and Figure 3Two locking blocks 122 are integrally formed on the rear surface of the disassembly shell 12, arranged in a left-right direction on the rear surface of the disassembly shell 12 near the left and right sides. The locking blocks 122 extend in a front-rear direction, and barbs are formed on their rear ends. A slot 111 for inserting the locking blocks 122 is formed on the inner wall of the front lobe shell 118. When the disassembly shell 12 is installed, the barbs of the locking blocks 122 press against the inner wall of the front lobe shell 118, forcing the locking blocks 122 to deform, allowing them to slide along the inner wall of the front lobe shell 118, and finally, the barbs of the locking blocks 122 engage in the slot 111. In other embodiments, the disassembly shell 12 and the front lobe shell 118 can be detachably connected by a bolt assembly.

[0043] Reference Figure 4 and Figure 5 An inclined guide surface 113 is formed on the inner wall surface of the front lobe housing 118 near the disassembly housing 12 and on the rear surface of the barb of the locking block 122. The distance between the guide surfaces 113 on the two locking blocks 122 decreases in the direction in which the disassembly housing 12 is inserted into the front lobe housing 118. When the disassembly housing 12 is installed, the guide surfaces 113 on the front lobe housing 118 slide against the guide surfaces 113 on the locking blocks 122, thereby guiding the deformation of the locking blocks 122. In other embodiments, the guide surfaces 113 may be provided only on the front lobe housing 118 or only on the locking blocks 122.

[0044] Reference Figure 5 The front surface of the barb of the locking block 122 has an unlocking arc surface 125, and the groove wall of the locking slot 111 has a guiding arc surface 114. The unlocking arc surface 125 and the guiding arc surface 114 have the same bending direction, both bending backward, so that the structure of the unlocking arc surface 125 and the guiding arc surface 114 are compatible and can fit together.

[0045] Reference Figure 5 A transition plane 115 is formed between the guide surface 113 and the guide arc surface 114, and the transition plane 115 abuts against the overhang section in front of the barb of the locking block 122.

[0046] Reference Figure 2 and Figure 3 Multiple limiting blocks 126 are integrally formed on the rear surface of the disassembly shell 12. Multiple limiting grooves 116 are opened on the surface of the front lobe shell 118 near the disassembly shell 12 for different limiting blocks 126 to be inserted. The limiting blocks 126 abut against the groove wall of the limiting groove 116, thereby limiting the disassembly shell 12.

[0047] Reference Figure 2 and Figure 3Hand-held blocks 124 are integrally formed on both the left and right surfaces of the rear end of the disassembly shell 12. The hand-held blocks 124 extend along the extension direction of the barbs of the locking block 122, that is, in the left and right direction. The hand-held blocks 124 are for human hand squeezing or pushing.

[0048] Reference Figure 3 A mounting hole 121 is provided through the front surface of the disassembled shell 12. A transparent observation window 4 is snapped into the mounting hole 121, allowing the user to observe the inner cavity of the shell 1 through the observation window 4.

[0049] Reference Figure 1 and Figure 6 A drive source 5, which is a drive motor, is installed inside the cavity of the mounting shell 11. The output shaft of the drive source 5 is connected to the moving cutter head 3, enabling the moving cutter head 3 to move. A seal 6 is press-fitted between the front shell 118 and the other shell 117. The seal 6 is made of rubber and presses against the body of the drive source 5 to achieve a sealing effect, preventing liquid or hair from entering the cavity of the shell 1 below the drive source 5 through the gap between the two shells 117.

[0050] The implementation principle of the easy-to-clean hair clipper according to this application embodiment is as follows: When installing or removing the housing 12, first insert the positioning block 123 into the positioning groove 112, rotate the housing 12 so that the locking block 122 is engaged in the locking groove 111, and at the same time, the limiting block 126 is inserted into the limiting groove 116. During use, the user can observe the accumulation of hair clippings in the inner cavity of the housing 1 through the observation window 4. When too much hair clippings have accumulated, the user squeezes the hand block 124 to push the locking block 122 out of the locking groove 111, rotates the housing 12, and removes the positioning block 123 from the positioning groove 112, thus completing the removal of the housing 12.

[0051] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
