Description

TECHNICAL FIELD

[0001] The present application relates to a hair trimming tool, more particularly to a magnetic hair clipper, and belongs to the field of beauty and hairdressing tools. BACKGROUND

[0002] After use, the existing hair clippers will have more or less broken hair adhering or accumulating on the inner and outer sides of the cutter assembly. In order to prevent the broken hair from affecting the subsequent use of the cutter assembly and reducing the trimming efficiency and trimming effect of the cutter assembly, the hair clippers will generally use a brush to clean the cutter assembly after use to remove the broken hair on the cutter assembly of the hair clippers.

[0003] There are mainly two ways to fix the existing trimming cutter and the shell:

[0004] One is fixed, that is, the cutter assembly is fixedly connected with the shell. Although this installation method can avoid displacement of the cutter assembly during use, it ensures the hair trimming performance of the cutter assembly and reduces vibration and working noise. However, it is not easy to clean the broken hair adhering to the inner side of the cutter assembly after use, which not only affects the subsequent use performance of the cutter assembly, but also easily causes bacteria to breed in the inner side of the cutter assembly in the shell.

[0005] The second is the buckle type, that is, the cutter assembly and the shell are connected by a hook structure. Although this structure can disassemble the cutter assembly for cleaning after use, the cutter assembly is prone to misalignment or displacement due to the machining precision and fitting precision of the hook, which not only affects the trimming performance of the cutter assembly, but also increases the vibration and working noise of the hair clipper during use.

[0031] The embodiments of the present invention will be further described below with reference to the accompanying drawings:

[0032] like Figures 1-9 As shown, the present invention is a magnetic-type hair clipper comprising a housing 1 and a blade assembly 2. The blade assembly 2 is mounted at a port of the housing 1 and synchronized with a drive mechanism 3 fixed within the housing 1. The end of the blade assembly 2, away from the cutting teeth, is retained by the housing 1, while the other end is magnetically connected to the housing 1, capable of being separated from the housing 1 by an external force. Connecting one end of the blade assembly 2 to the housing 1 and forming a retaining mechanism effectively prevents movement or displacement of the blade assembly 2 during use, thereby ensuring operational stability. Furthermore, the end of the blade assembly 2, provided with the cutting teeth, is magnetically connected to the housing 1, utilizing the magnetic properties of the magnetic material to secure the blade assembly 2 and the housing 1. Compared to complex hook-and-hook or snap-fit ​​connections, this effectively simplifies the connection structure between the blade assembly 2 and the housing 1, reduces mold manufacturing difficulty, improves component yield, and reduces production costs. Furthermore, it ensures a secure connection between the blade assembly 2 and the housing 1 during use (this secure connection can be achieved by controlling the magnetic flux of the magnetic object) and ensures the hair cutting performance of the hair clippers. Secondly, after the use of the hair clippers, a certain thrust can be applied to one end of the magnetic connection between the cutter head assembly 2 and the shell 1 to separate the cutter head assembly 2 from the shell 1, so that the inside of the cutter head assembly 2 or the shell 1 can be easily cleaned and maintained, avoiding the accumulation of broken hair that affects the hair trimming performance of the cutter head assembly 2 and preventing the accumulation of broken hair in the shell 1 from breeding bacteria, thereby improving the hygiene and safety of the hair clippers.

[0033] Prevent the knife head assembly 2 from moving or displacement during use, affect the hair trimming performance of the knife head assembly 2 and improve the vibration feeling or working noise of the hair clipper, etc. In the actual production process, the end of the knife head assembly 2 away from the cutting teeth is hinged to the shell 1, the lower end of the knife head assembly 2 (i.e. relative to the end provided with the cutting teeth) is hinged to the shell 1, and the lower end of the knife head assembly 2 is limited with the shell 1 by using the hinge structure, so that the up and down movement or displacement of the knife head assembly 2 can be effectively prevented, not only the hair trimming performance of the knife head assembly 2 is ensured, but also the vibration feeling and working noise of the hair clipper during use can be effectively reduced, and the use comfort of the hair clipper is improved. Of course, in order to limit the connection between the lower end of the knife head assembly 2 and the shell 1, the hinge method can not be used. For example, a pin hole is provided at the corresponding position of the lower end of the knife head assembly 2 and the shell 1 respectively, and the knife head assembly 2 is connected and fixed with the shell 1 by inserting a pin shaft into the pin hole, which also has a limiting effect, but the pin shaft is not easy to take out, and it is not convenient to clean the inside of the knife head assembly 2 and the shell 1, so the embodiment of the present embodiment is the preferred embodiment. In order to facilitate the cleaning of the inside of the knife head assembly 2 and the shell 1, at least one side of the end of the knife head assembly 2 provided with the cutting teeth is fixedly provided with a connecting block 215 with magnetic property or magnetically attracted, and is magnetically connected with the shell 1. At least one side of the end of the knife head assembly 2 provided with the cutting teeth (of course, it can be selected according to the vibration intensity of the hair clipper, for example, when the vibration intensity of the hair clipper is large, the connecting block 215 with magnetic property or magnetically attracted can be installed on both sides of the end of the knife head assembly 2 provided with the cutting teeth) is provided with a magnetic body or a connecting block 215 which can be magnetically attracted by a magnetic body and is magnetically connected with the shell 1, the knife head assembly 2 and the shell 1 are connected by using magnetism, so that the structure of the knife head assembly 2 and the shell 1 is greatly optimized, not only the structure of the knife head assembly 2 and the shell 1 is simple, but also the product yield can be greatly improved during production, the production cost and the mold manufacturing difficulty of the knife head assembly 2 and the shell 1 are reduced; at the same time, the connection firmness of the knife head assembly 2 and the shell 1 is effectively ensured, and the hair trimming performance of the knife head assembly 2 is improved. Secondly, when necessary, the knife head assembly 2 and the shell 1 can be separated conveniently, the inside of the knife head assembly 2 and the shell 1 can be cleaned conveniently, the hair trimming performance of the knife head assembly 2 is not reduced due to the accumulation of hair fragments, and the health safety of the hair clipper is improved. In the actual production and assembly process, a magnetic object (such as a magnet or the like) can be provided on one side or both sides of the upper end (i.e. the end provided with the cutting teeth) of the knife head assembly 2 and in the shell 1 to magnetically connect the knife head assembly 2 and the shell 1. A magnetic object (such as a magnet or the like) can also be provided on one of the knife head assembly 2 and the shell 1, and a magnetically attracted object (such as an iron block or the like) can be provided on the corresponding position of the other, so that the knife head assembly 2 and the shell 1 can be magnetically connected. The specific setting can be determined according to user requirements or the actual connection strength of the knife head assembly 2 and the shell 1, and the present embodiment is not limited further.

[0034] Due to the secretion of human body oil and the need for lubrication of the cutter head assembly 2, the human body hair after trimming will more or less stick some human body oil or lubricating oil. After the hair clipper is used, the hair will stick to the inner and outer sides of the cutter head assembly 2. If the cutter head assembly 2 is directly pushed away from the shell 1 by hand, the broken hair will directly stick to or stick into the skin of the hand or body, which is easy to cause local inflammation of the skin and has a hidden danger of health and safety. Therefore, the shell 1 is provided with a button 4, which can be displaced along the shell 1 under the action of external force to drive the end of the cutter head assembly 2 magnetically connected with the shell 1 to be separated from the shell 1. By adding the button 4 in the shell 1, the button 4 can be pushed by the finger when needed to drive the end of the cutter head assembly 2 magnetically connected with the shell 1 to be separated from the shell 1, so that the inside of the cutter head assembly 2 or the inside of the shell 1 can be conveniently cleaned, the broken hair is effectively prevented from directly sticking to or sticking into the skin of the hand or body, and the health and safety performance of the hair clipper is improved.

[0035] In order to facilitate the production and assembly of the hair clipper, the shell 1 includes an upper shell 11 and a lower shell 12, the end of the cutter head assembly 2 away from the cutting teeth is provided with a hinge seat 211 and is hingedly connected with the lower shell 12, and at least one side of the end of the cutter head assembly 2 provided with the cutting teeth is magnetically connected with the upper shell 11; the button 4 is fixed in the upper shell 11 and can drive the cutter head assembly 2 to be separated from the upper shell 11 and be flipped open along the lower shell 12 under the action of external force. The shell 1 is provided as a split structure, which not only facilitates the injection molding of the upper shell 11 and the lower shell 12, improves the production efficiency, but also facilitates the installation of components with magnetism or being magnetically attracted, and effectively improves the assembly efficiency of the hair clipper.

[0036] To prevent the knife head assembly 2 from moving or shifting during work and affecting the hair trimming performance of the knife head assembly 2, the knife head assembly 2 comprises a static knife seat 21, a static knife blade 22 mounted on the static knife seat 21, a dynamic knife 23 connected with a dynamic knife seat 24 and abutting against the static knife blade 22, and the dynamic knife seat 24 is connected with the driving mechanism 3; a hinged seat 211 is arranged at the lower end of the static knife seat 21, the hinged seat 211 comprises a hinged bottom plate 2111, a guard plate 2112 is arranged on each side of the hinged bottom plate 2111, and a hinged shaft 2113 is arranged on each guard plate 2112; a missing groove 121 is arranged at the corresponding position of the lower shell 12, a positioning plate 122 with an inclined outer end surface is arranged on each side of the missing groove 121, and a hinged hole 123 is arranged on the positioning plate 122; the hinged shaft 2113 is arranged in each hinged hole 123, and the inclined surface of each positioning plate 122 abuts against the end surface of the static knife seat 21, so that the lower end of the static knife seat 21 is hingedly fixed with the lower shell 12. By arranging the hinged bottom plate 2111 at the lower end of the static knife seat 21 into the missing groove 121 of the lower shell 12, and by cooperating the hinged shaft 2113 of each guard plate 2112 with the hinged hole 123 of the positioning plate 122, the static knife seat 21 of the knife head assembly 2 can be turned and opened along the missing groove 121 of the lower shell 12, which not only facilitates cleaning the inside of the knife head assembly 2 and the inside of the upper shell 11 and the lower shell 12, avoids breeding of bacteria due to accumulation of hair fragments inside the knife head assembly 2 and inside the upper shell 11 and the lower shell 12, and improves the health and safety of the hair clipper, but also effectively limits the knife head assembly 2, prevents the knife head assembly 2 from moving or shifting during work, and ensures the hair trimming performance of the knife head assembly 2.

[0037] To prevent the static knife seat 21 from moving or shifting during work of the knife head assembly 2, a limiting table 124 is arranged on one side of each positioning plate 122 in the lower shell 12; a limiting block 212 is arranged at the corresponding position of the lower end of the static knife seat 21, and the lower end surface of the limiting block 212 abuts against the upper end surface of the limiting table 124 when the knife head assembly 2 is magnetically connected with the upper shell 11. By arranging the limiting table 124 on the lower shell 12 and by arranging the limiting block 212 on the static knife seat 21 to abut against the end surface of the limiting table 124 when the knife head assembly 2 is magnetically connected with the shell 1, a limiting effect is achieved, the working stability of the knife head assembly 2 is further improved, and the static knife seat 21 is prevented from moving or shifting during work of the knife head assembly 2. In actual production, the limiting table 124 is integrated with the positioning plate 122, which can significantly improve the working strength of the positioning plate 122 and the limiting table 124 and prevent deformation of the positioning plate 122 and the limiting table 124 from causing the static knife seat 21 to move or shift.

[0038] In the hair cutting process, especially in the trimming of short hair or bald hairstyle, the static blade 22 needs to be trimmed along the skin of the head, so the static blade 22 is installed in the groove on the outer side of the static blade seat 21 so that the outer side of the static blade 22 protrudes or is flush with the outer side of the static blade seat 21. Since the hair trimming process of the cutter head assembly 2 is completed by the reciprocating swing of the dynamic blade 23 along the inner side of the static blade 22 driven by the driving mechanism 3, in order to prevent interference with the reciprocating swing of the dynamic blade 23 and the dynamic blade seat 24 and affect the hair trimming efficiency of the cutter head assembly 2, a U-shaped opening 213 is provided at the upper end of the static blade seat 21; by providing the U-shaped opening 213, the dynamic blade 23 and the dynamic blade seat 24 are placed in the U-shaped opening 213 and reciprocate in the U-shaped opening 213 under the drive of the driving mechanism 3. In order to facilitate the magnetic connection of the cutter head assembly 2 and the shell 1, a clamping seat 214 is provided on both sides of the U-shaped opening 213, and a connecting block 215 is fixed in each clamping seat 214; a fixed seat 111 is provided on the inner side wall of the upper shell 11, and a magnetic block 112 with magnetism or magnetically attracted is installed in each fixed seat 111, and the magnetic block 112 and the connecting block 215 are magnetically connected to make the upper end of the static blade seat 21 and the upper shell 11 separable. By providing a clamping seat 214 on both sides of the U-shaped opening 213 of the static blade seat 21, and installing a connecting block 215 in each clamping seat 214. At the same time, the magnetic block 112 is provided at the corresponding position of the inner side wall of the upper shell 11, and the magnetic force of the magnetic block 112 is used to magnetically connect the magnetically attracted connecting block 215, so that the upper end of the cutter head assembly 2 and the upper shell 11 are separably magnetically fixed. In the actual production and assembly process, the connecting block 215 and the magnetic block 112 can both have magnetism, or one of them has magnetism, and the specific setting can be determined according to user requirements. The clamping seat 214 and the fixed seat 111 are conventional structures, as long as they facilitate the demolding of the integral injection molding of the static blade seat 21 and the upper shell 11.

[0039] Taking into account the demoulding and magnetic connection firmness of the upper shell 11 after integral injection molding, the opening of the fixed seat 111 is set on the side, and the fixed seat 111 is used to limit the contact surface of the magnetic block 112 and the connecting block 215, ensuring that the cutter head assembly 2 will not pull the magnetic block 112 out of the fixed seat 111 after being subjected to force. In order to prevent the magnetic block 112 from sliding out of the fixed seat 111 due to the vibration generated by the high-speed rotation of the driving mechanism 3, a baffle 125 is provided in the lower shell 12 to cover the openings of each fixed seat 111 of the upper shell 11. The front end surface of each baffle 125 is an inclined surface, and when the cutter head assembly 2 is magnetically connected to the upper shell 11, the inclined surface of the baffle 125 forms a limiting fit with the end surface of the static knife seat 21. By providing a baffle 125 on the inner side wall of the lower shell 12, when the lower shell 12 and the upper shell 11 are combined to form a whole, the baffle 125 can cover the side openings of each fixing seat 111 in the inner side wall of the upper shell 11, thereby effectively preventing the magnetic block 112 installed in the fixing seat 111 from sliding out when the driving mechanism 3 rotates at high speed and generates vibration, thereby improving the magnetic connection strength between the cutter head assembly 2 and the shell 1. The front end surface of each baffle 125 is set to be inclined. When the cutter head assembly 2 is magnetically connected to the shell 1, the inclined surface of the front end of the baffle 125 can press against the inner side surface of the static blade seat 21 of the cutter head assembly 2, forming a limit for the cutter head assembly 2, thereby preventing the cutter head assembly 2 from moving or displacing during operation to the greatest extent, and ensuring the working stability of the cutter head assembly 2.

[0040] When the hair clippers need to be cleaned after use, in order to avoid direct contact between the hands and the cutter head assembly 2 and to prevent broken hair from piercing the skin of the hands or body and causing local infection of the skin, the button 4 includes a button body 41 and a slider 42. A positioning pin 411 is provided at the bottom of the button body 41, and hooks 412 are provided on both sides of the positioning pin 411; a positioning countersunk hole 421 is provided on the upper end surface of the slider 42, and through holes 422 are provided on both sides of the positioning countersunk hole 421; the positioning pin 411 is inserted into the positioning countersunk hole 421, and the two hooks 412 respectively pass through the through holes 422 and hook with the end surface of the slider 42 to fix the button body 41 and the slider 42; in order to strengthen To enhance the strength of the button 4, a positioning pin 411 is provided at the bottom of the button body 41. The positioning pin 411 is inserted into the positioning countersunk hole 421 of the slider 42. When the cutter head assembly 2 and the housing 1 need to be separated, the button body 41 can be pushed with a finger. The button body 41 drives the positioning pin 411, causing the slider 42 to move along the upper housing 11 and push against the side of the movable blade seat 24 of the cutter head assembly 2, overcoming the magnetic force between the connecting block 215 and the magnetic block 112. This causes the stationary blade seat 21 of the cutter head assembly 2 to separate from the upper housing 11 and flip open along the hinge seat 211, making it easier to clean the inside of the cutter head assembly 2 and the interiors of the upper and lower housings 11 and 12. To ensure the secure connection between the button body 41 and the slider 42, hooks 412 are provided on either side of the positioning pin 411. The hooks 412 engage in the through-hole 422 of the slider 42 and hook onto the sidewall of the through-hole 422, thereby enhancing the secure connection between the button body 41 and the slider 42. In actual production, to prevent the hook 412 from protruding from the end face of the slider 42, a groove 424 is provided on one side of the through hole 422. The hook 412 is placed in the through hole 422, and its hook teeth cooperate with the groove 424, so that the hook 412 is completely placed in the slider 42 and does not protrude from the end face of the slider 42, thereby preventing the hook 412 from interfering with the displacement of the slider 42. A sliding groove 113 is provided in the upper shell 11, and both sides of the sliding groove 113 are connected, so that the slider 42 is driven by the button body 41 to move along the sliding groove 113 and drive the end of the blade assembly 2 that is magnetically connected to the upper shell 11 to separate from the shell 1. By providing the sliding groove 113 in the upper shell 11 and making both ends of the sliding groove 113 connected, when the button body 41 is installed in the sliding groove 113, the two ends of the slider 42 respectively pass through the sliding groove 113 and are placed in the upper shell 11. When the cutter head assembly 2 and the housing 1 need to be cleaned, the button body 41 can drive the slider 42 to move along the sliding groove 113 under the push of the finger to separate the cutter head assembly 2, thereby facilitating cleaning of the cutter head assembly 2 and the inside of the housing 1.

[0041] In order to facilitate the hair clip to adapt to water cleaning, the partition plate 114 is arranged at the corresponding position of the upper shell 11 and the lower shell 12 respectively, so that the shell 1 is divided into two independent cavities, the output shaft of the driving mechanism 3 passes through the partition plate 114 and is connected with the movable cutter holder 24 of the cutter head assembly 2 in linkage. The baffle 125 in the lower shell 12 is connected with the partition plate 114 in the lower shell 12 integrally. By arranging the partition plate 114 at the corresponding position of the upper shell 11 and the lower shell 12 respectively, when the upper shell 11 and the lower shell 12 are combined, two independent cavities can be formed in the shell 1 due to the blocking of the partition plate 114, wherein the front end cavity is used for accommodating the cutter head assembly 2 and the eccentric wheel of the driving mechanism 3, and the other cavity can be used for installing the circuit board, the motor of the driving mechanism 3 and other electronic components. When the hair clip needs to be cleaned, the button 4 is driven to separate the cutter 23 head assembly 2 from the shell 1 under the pushing of the finger, and after the cutter head assembly 2 is turned open along the hinge seat 211, the inside of the cutter head assembly 2 and the front end inside of the upper shell 11 and the lower shell 12 can be directly washed with water, which can effectively save the cleaning time and improve the cleaning benefit while ensuring the cleaning effect.

[0042] In the actual production process, in order to prevent the button body 41 and the sliding block 42 from shaking under the high-speed rotation of the driving mechanism 3 and improving the working noise of the hair clip, the clamping groove 5 composed of two limiting arms 423 is arranged at the end of the sliding block 42, the clamping tongue 4231 is arranged at the end of each limiting arm 423, the opening width of the clamping groove 5 is smaller than the end width, and the arc-shaped notch 4232 is arranged behind each clamping tongue 4231; the limiting column 115 is arranged on the inner wall of the upper shell 11, and the cross section is preferably oval. When the button 4 is not needed, the button body 41 is displaced to the rear end of the shell 1 along the sliding groove 113, under the influence of the pushing force of the button body 41 and the resistance of the limiting column 115, the clamping tongue 4231 at the end of the limiting arm 423 will automatically expand outward and pass over the limiting column 115, so that the arc-shaped notch 4232 of each limiting arm 423 is clamped into the two sides of the limiting column 115 respectively, thereby forming the fixed connection between the sliding block 42, the button body 41 and the upper shell 11. In this way, the shaking or displacement of the button body 41 and the sliding block 42 under non-human operation during the working process of the hair clip can be effectively avoided, and the working noise of the hair clip is reduced.

[0043] The above embodiments should not be regarded as a limitation of the present application, but any improvement based on the spirit of the present application should be within the protection scope of the present application.
