Description

Technical Field

[0001] This utility model belongs to the field of hair clipper technology, specifically relating to a guide installation structure for a magnetic cleaning cover for a hair clipper. Background Technology

[0002] As a frequently used hair trimming tool, a hair clipper typically consists of a housing, a blade unit, and a drive unit. Its working principle is that the drive unit drives the blade unit to oscillate at high speed, thereby cutting the hair. However, during continuous operation, the cut hair clippings are easily carried by airflow or gravity from around the blade unit into the housing and accumulate in the drive unit or at the linkage between the blade unit and the drive unit. Because the hair clippings are small, tough, and often contain sebum and dust, long-term accumulation can easily cause problems such as the drive unit jamming, stopping, reduced cutting accuracy leading to hair-clamping pain, and obstructed heat dissipation. Therefore, it is necessary to clean the hair clippings inside the housing regularly. However, to ensure structural strength and aesthetic integrity, existing hair clippers often use screws or hidden clips for connection. Users need to use special tools to remove the face cover and blade unit, making the disassembly and cleaning process quite complicated and tedious, which seriously affects the user experience.

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] like Figure 1-5 As shown, this utility model provides a guide installation structure for a magnetic cleaning cover for a hair clipper, including a body 1. The body 1 is provided with a blade unit 8 located at the working end and a drive unit 9 for driving the blade unit 8 to cut hair. A cleaning position 2 is provided on the outer surface of the body 1. The cleaning position 2 is connected to the connection between the blade unit 8 and the drive unit 9, so that the user can directly clean the broken hairs of the blade unit 8, the drive unit 9 and the connection between them through the cleaning position 2. To improve the ease of disassembly and cleaning for users, a cleaning cover 3 can be detachably and magnetically connected to the cleaning position 2. The cleaning position 2 has a centrally located first magnetic suction member 21, and the cleaning cover 3 has a second magnetic suction member 31 that magnetically engages with the first magnetic suction member 21. The cleaning position 2 also has two first guide members 22 symmetrically arranged around the first magnetic suction member 21, and the cleaning cover 3 has a second guide member 32 that plugs into and engages with the first guide members 22. The first magnetic suction member 21 and the two first guide members 22 are arranged as vertices of a triangle to form a triangular layout, thereby achieving three-point fixed positioning of the cleaning cover 3. During installation, the cleaning cover 3 is installed from the outside towards the cleaning position 2. First, the first guide 22 and the second guide 32 are aligned and fitted together. Then, under the guidance of the first guide 22 and the second guide 32, the cleaning cover 3 moves precisely towards the cleaning position 2 in the extension direction of the first guide 22 (i.e., the insertion and removal direction of the cleaning cover 3). At the same time, the first magnetic suction member 21 and the second magnetic suction member 31 are synchronously and precisely paired. When the first magnetic suction member 21 and the second magnetic suction member 31 are attracted and attached to each other, the assembly of the cleaning cover 3 and the body 1 is completed, thereby covering and sealing the cleaning position 2 and preventing hair fragments from directly entering the body 1 from the cleaning position 2 during use. When it is necessary to clean up hair clippings, simply remove the cleaning cover 3 outwards along the insertion / removal direction, and then use a brush to clean the hair clippings inside the cleaning position 2. Through the insertion / removal guidance of the first guide member 22 and the second guide member 32, the cleaning cover 3 can only be removed from the body 1 along the insertion / removal direction, effectively preventing the cleaning cover 3 from shaking or even falling off in the horizontal direction (perpendicular or nearly perpendicular to the insertion / removal direction) after installation, which would affect the user experience. At the same time, since the magnetic attraction direction of the first magnetic member 21 and the second magnetic member 31 is consistent with the insertion / removal direction of the cleaning cover 3, the cleaning cover 3 is effectively attracted and fixed in the insertion / removal direction. Under the action of magnetic attraction, it is more convenient and effortless for users to install and remove the cleaning cover 3.

[0027] Specifically, such as Figure 4-6 As shown, the body 1 is provided with a cantilever platform 23 extending into the cleaning position 2. The cantilever platform 23 is provided with a mounting groove 231 for accommodating the first magnetic suction member 21, so that the first magnetic suction member 21 is located in the center of the cleaning position 2. At this time, the top surface of the first magnetic suction member 21 is flush with the top surface of the cantilever platform 23. Furthermore, such as Figure 5As shown, the bottom of the cleaning cover 3 is provided with a fixing post 33 extending along the insertion and removal direction, and the second magnetic suction member 31 is disposed on the top of the fixing post 33, so that the mounting groove 231, the first magnetic suction member 21, the second magnetic suction member 31 and the fixing post 33 are all on the same axis. At the same time, in the assembled state, the first magnetic suction member 21 and the second magnetic suction member 31 can be effectively magnetically attracted and attached, further enhancing the magnetic attraction between the two, thereby improving the adsorption stability of the cleaning cover 3. In this embodiment, the first magnetic suction component 21 is preferably a magnet 4, and the second magnetic suction component 31 is preferably an iron screw 5. The effective magnetic attraction of the magnet 4 and the screw 5 improves the adsorption stability of the cleaning cover 3 and the ease of disassembly and cleaning. At the same time, in order to adapt to actual production needs, the installation positions of the magnet 4 and the screw 5 can be interchanged, or the second magnetic suction component 31 can also be a magnet 4, without affecting the actual use effect. In this embodiment, the effective magnetic fixation of the cleaning cover 3 can be achieved by using only one magnet 4, which not only effectively saves the production cost of the hair clipper, but also optimizes the user experience, making it more convenient to disassemble and assemble the cleaning cover 3.

[0028] Specifically, such as Figure 4 and Figure 5 As shown, in this embodiment, the first guide member 22 is preferably a guide post 6, while the second guide member 32 is preferably a guide groove 7 surrounded by a second reinforcing rib 35 with a "C" shape. The extension direction of the second reinforcing rib 35 is consistent with the insertion and extraction direction. The second reinforcing rib 35 adopts a non-closed-loop "C" shape structure, which makes it have elastic deformation performance, which is conducive to draft forming and insertion and engagement with the first guide member 22.

[0029] By setting the second reinforcing rib 35, not only can the structural strength of the cleaning cover 3 be effectively improved, but also the installation guidance of the cleaning cover 3 and the connection stability between the cleaning cover 3 and the body 1 can be realized through the insertion and removal guidance of the guide groove 7 and the guide post 6. At the same time, in order to adapt to actual production needs, the installation positions of the guide post 6 and the guide groove 7 can be interchanged without affecting the actual use effect. like Figure 7 As shown, in order to further improve the accuracy of the alignment of the first guide member 22 and the second guide member 32, the outer wall of the top end of the guide post 6 is provided with a tapered surface 61 that extends inward in an annular shape, so that the top end of the guide post 6 has a tapered structure; similarly, the inner wall of the opening end of the guide groove 7 is also provided with a transition surface 71 that extends outward in an annular shape (inverted trumpet shape). Therefore, by increasing the inner wall diameter of the opening end of the guide groove 7 and decreasing the outer wall diameter of the top end of the guide post 6, the purpose of quickly matching and docking the two can be effectively improved.

[0030] Specifically, such as Figure 1 As shown, during cleaning, the user only needs to pull the cleaning cover 3 outward in the insertion and removal direction, and then use the brush to clean the hair inside the cleaning position 2. It is simple and convenient, which helps to improve the user's ease of use. Furthermore, to allow for a clearer and more detailed observation of the internal workings of the machine body 1, a viewing window 11 adjacent to the cleaning station 2 is provided on the outer surface of the machine body 1. A transparent cover 12 is detachably connected to the viewing window 11, allowing the user to directly observe the operating status of the drive unit 9 and the blade unit 8 inside the machine body 1 during use. A button 13 is also provided on the outer surface of the machine body 1. The button 13, the transparent cover 12, and the viewing window 11 are all hexagonal in shape, creating a uniform and aesthetically pleasing appearance. An indicator light 14 is also provided on the outer surface of the machine body 1. The indicator light 14, the button 13, and the transparent cover 12 are linearly spaced along the extension direction of the outer surface of the machine body 1, making the machine body 1 more harmonious and aesthetically pleasing in appearance.

[0031] Specifically, such as Figure 5-6 As shown, the outer surface of the cleaning cover 3 also adopts an arc-shaped structure, which effectively improves the overall structural strength of the cleaning cover 3, and can also be aligned and smoothly transitioned with the surface of the body 1, making the appearance of the hair clipper more consistent and beautiful. Furthermore, the cleaning cover 3 is provided with first reinforcing ribs 34 that are spaced apart and extend laterally on the end face facing the cleaning position 2, and the second reinforcing ribs 35 and the fixing post 33 are all provided between the two first reinforcing ribs 34, thereby further enhancing the overall structural strength of the cleaning cover 3. Furthermore, to facilitate the user's disassembly and assembly of the cleaning cover 3, symmetrically arranged gripping protrusions 36 are provided on the two end side walls of the cleaning cover 3. The user can use two fingers to simultaneously grip and contact the gripping protrusions 36 to disassemble, assemble, move, and grasp the cleaning cover 3. Preferably, such as Figure 3 As shown, the edge of the cleaning position 2 is also provided with a "C"-shaped interface 24 that corresponds to the hexagonal element, and the cleaning cover 3 is provided with a matching "C"-shaped alignment edge 37, which makes the overall appearance of the hair clipper more consistent and thus effectively improves the overall aesthetics. The matching "C"-shaped alignment structure makes it convenient for users to directly align and match the cleaning cover 3 for disassembly and assembly.

[0032] Specifically, such as Figure 8-9As shown, the drive unit 9 includes a motor 91 and an eccentric shaft 92. The eccentric shaft 92 is mounted on the output shaft of the motor 91, and their axes are not on the same straight line to form an eccentric arrangement. This allows the eccentric shaft 92 to rotate eccentrically around the output shaft of the motor 91 when the motor 91 drives it to rotate. The tool unit 8 includes a fixed tool 81, a moving tool 82, and a tool holder 83. The bottom surface of the moving tool 82 is laterally and reciprocally slidably connected to the top surface of the fixed tool 81. The top surface of the moving tool 82 is fixedly connected to the bottom of the tool holder 83. The tool holder 83 is provided with a transmission groove 831, and the eccentric shaft 92 extends into the transmission groove 831 to drive the movement of the tool holder 83 and the moving tool 82. Wherein, the width D of the transmission groove 831 (e.g. Figure 8 ) and the diameter R of the eccentric shaft 92 (e.g. Figure 9 To ensure compatibility, the height H of the transmission groove 831 is greater than the diameter R of the eccentric shaft 92 (e.g., ...). Figure 9 Therefore, when the eccentric shaft 92 performs eccentric circular motion, the eccentric shaft 92 can drive the tool holder 83 and the moving tool 82 to reciprocate synchronously in the lateral direction relative to the motor 91 and the fixed tool 81; while in the height direction, since the height H of the transmission groove 831 is greater than the diameter R of the eccentric shaft 92, the up and down movement of the eccentric shaft 92 can be released within the transmission groove 831, and therefore will not drive the tool holder 83 to reciprocate in the height direction. Furthermore, such as Figure 8 As shown, in order to limit the swing amplitude of the eccentric shaft 92 in the height direction and prevent the eccentric shaft 92 from disengaging from the upper opening 832 of the transmission groove 831, a horizontally arranged limiting rod 833 is also provided at the upper opening 832 of the transmission groove 831. The setting of the limiting rod 833 can not only limit the up and down swing amplitude of the eccentric shaft 92, but also effectively improve the structural strength of the tool holder 83. Meanwhile, in order to effectively reduce the friction area between the eccentric shaft 92 and the limiting rod 833, and thus reduce their friction noise, the limiting rod 833 should not be too wide or too thick; therefore, in this embodiment, the width of the limiting rod 833 is adapted to the width D of the transmission groove 831 (e.g., Figure 8 While increasing the overall rigidity of the tool holder 83, it can also effectively limit the eccentric shaft 92; and the cross-sectional area S1 of the limiting rod 833 (e.g. Figure 9 This is much smaller than the cross-sectional area S2 of the eccentric shaft 92 (e.g. Figure 8This reduces the friction area between the limiting rod 833 and the eccentric shaft 92, further reducing friction noise. In this embodiment, the ratio of the cross-sectional area S1 of the limiting rod 833 to the cross-sectional area S2 of the eccentric shaft 92 can be between 0.2 and 0.5, thereby ensuring that the friction area between the two is small enough while also having an effective limiting effect. Preferably, such as Figure 6 As shown in Figure 9, the front end of the blade holder 83 is also provided with a baffle 834 extending laterally. The baffle 834 is located inside the connecting seam 835 between the top surface of the moving blade 82 and the bottom end of the cleaning cover 3. By setting the baffle 834, the connecting seam 835 is effectively prevented from being directly connected to the transmission groove 831 and the drive unit 9 in a straight line, preventing hair fragments from directly entering the transmission groove 831 and the drive unit 9 through the connecting seam 835, causing a large amount of hair fragments to accumulate and block the machine body 1.

[0033] The following is a detailed explanation of the working principle of this utility model; When cleaning up stray hairs, the user can use their fingers to hold and press against the gripping protrusions 36 and pull the cleaning cover 3 outward in the insertion and removal direction. At this time, the user can use a brush to clean the stray hairs inside the body 1 through the cleaning position 2. After cleaning, the user only needs to align and bring the matching "C"-shaped alignment structures close together. The second guide 32 in the cleaning cover 3 and the first guide 22 in the cleaning position 2 will naturally align synchronously. The user then inserts the cleaning cover 3 into the cleaning position 2 along the insertion / removal direction. When the first magnetic suction member 21 in the cleaning position 2 and the second magnetic suction member 31 in the cleaning cover 3 are close enough, the cleaning cover 3 will automatically adhere to the cleaning position 2 under the magnetic attraction of the two, thus completing the installation of the cleaning cover 3.

[0034] The innovation of this utility model lies in the fact that by using only one magnet and making full use of the guide post and guide groove with the function of upper and lower alignment, the cleaning cover can be quickly disassembled and assembled, which is conducive to the user's efficient and rapid cleaning of hair inside the machine, thereby improving the user experience; at the same time, by using the triangular layout of the magnet and guide post, the connection stability between the cleaning cover and the machine body is further improved while effectively reducing the production cost of the hair clipper.
