AI Technical Summary
When existing electric clippers are in operation, there is wear between the eccentric needle on the motor output shaft and the guide groove on the moving blade, resulting in loud noise. Furthermore, the increased wear leads to a decrease in cutting efficiency, which limits the product's lifespan and performance.
The magnetic silent electric clipper design utilizes the principle of like poles repulsion of magnets. The magnet pushes the guide groove on the moving blade, avoiding contact between the magnet and the side wall of the guide groove. This allows the moving blade to swing left and right on the fixed blade, and the magnetic attraction makes the moving blade and the fixed blade fit together, reducing friction and noise.
It effectively reduces the noise when the motor drives the moving blades, improves cutting efficiency and stability, and extends the service life of the electric clipper.

Description
TECHNICAL FIELD
[0001] The present application relates to the field of electric clippers, in particular to a magnetic silent electric clipper. BACKGROUND
[0002] Electric clippers are commonly used hairdressing and hair styling tools, mainly used for trimming human hair or animal fur, usually adopting a reciprocating structure, and a power source drives a blade to reciprocate through a mechanical structure to cut hair.
[0003] The output shaft of the existing electric clipper is provided with an eccentric needle, which is inserted between the blade pad guide grooves to drive the fixed blade to move left and right to achieve shearing. However, the eccentric needle of the existing structure is in contact with the blade pad guide groove, which will inevitably cause friction and generate heat. The heat will also cause the plastic guide groove to wear out faster. The wear of the two wear surfaces of the blade pad guide groove is uncontrollable, so the noise generated during movement is chaotic. As the wear intensifies, the shearing effect of the blade will also decrease sharply, and eventually lose the shearing function.
[0004] The rotating speed of the electric clippers on the market is basically below 8000 rpm / min, and rarely reaches 10000 rpm / min. The wear of the blade pad guide groove has a great relationship with the rotating speed. If the rotating speed of the electric clipper is increased, the wear of the blade pad guide groove will increase geometrically, and the service life of the electric clipper will be shortened, which seriously restricts the performance and iteration of electric clipper products.

[0061] As Figures 1 to 3As shown in the figure, a magnetic silent electric clipper includes a fixed blade 1 and a movable blade 2, the movable blade 2 swings left and right relative to the fixed blade 1 under the drive of a motor 4, the movable blade 2 is provided with a blade pad 21, a guide groove 211 on the blade pad 21 forms a transmission part for transmitting the power of the motor to the movable blade 2, the opposite two side walls 212 of the guide groove 211 are each provided with a first magnet 6, the output shaft 41 of the motor 4 is provided with a second magnet 7 deviating from the axis of the output shaft 41, the second magnet 7 is placed between the two side walls 212 of the guide groove 211, and the magnetism of the second magnet 7 is the same as that of the first magnet 6, when the output shaft 41 of the motor 4 rotates, the second magnet 7 moves in a circle around the output shaft 41 while moving back and forth between the two side walls 212, due to the principle of repulsion between the same magnets, the second magnet 7 pushes the adjacent side wall 212 with repulsive force, so that the second magnet 7 pushes the opposite two side walls 212 of the guide groove 211 in turn, so that the movable blade 2 swings left and right on the fixed blade 1.
[0062] As shown in the figure, Figure 4 In this embodiment, the second magnet 7 is a ring magnet 72, the ring magnet 72 is connected with an eccentric wheel 71, the center of one end surface of the eccentric wheel 71 is provided with a connecting shaft 711, the connecting shaft 711 is connected with the center of the ring magnet 72; the other end surface of the eccentric wheel 71 is provided with a plug-in hole 712 deviating from the center, the output shaft 41 is plugged into the plug-in hole 712. The output shaft 41 of the motor 4 is connected to the plug-in hole 712 deviating from the center of the eccentric wheel 71, and the ring magnet 72 is connected to the center of the eccentric wheel 71, so that the ring magnet 72 deviates from the axis of the output shaft 41 of the motor 4, and when the motor 4 rotates, the ring magnet 72 moves in a circle around the output shaft 41 as the axis.
[0063] As shown in the figure, Figure 10 and Figure 11 In a preferred embodiment, the ring magnet 72 includes a plurality of fan ring magnets 721 and a fixed ring 722, the plurality of fan ring magnets 721 are placed in the magnet placing positions 713 of the connecting shaft of the eccentric wheel 71 and are fixed by the fixed ring 722, and the plurality of fan ring magnets 721 enclose the ring magnet 72. For example, two fan ring magnets 721 are placed in the two magnet placing positions 713 of the connecting shaft of the eccentric wheel 71, and then the fixed ring 722 made of plastic is used to fix them. In other embodiments, four or other number of fan ring magnets can also be used.
[0064] As shown in the figure, Figure 6As shown in the figure, in the embodiment, the top of the moving blade 2 is provided with a cutter pad 21, the top of the cutter pad 21 is provided with a guide groove 211, and the guide groove 211 is formed by two opposite side walls 212, and has a slot for placing the first magnet 6. The side wall 212 of the guide groove 211 is hollow inside, forming a cavity for placing the first magnet 6, and the bottom of the cavity is provided with a insertion hole communicating with the inside of the side wall 212, facilitating the installation of the first magnet 6 into the side wall 212 through the insertion hole. Therefore, the installation of the first magnet 6 in the side wall 212 of the guide groove 211 from the insertion hole can realize that the guide groove has a slot with magnetism for placing the second magnet 7 with the same magnetism.
[0065] As can be seen, the second magnet 7 pushes the guide groove on the moving blade 2 by magnetic force according to the principle that magnets with the same magnetism repel each other, so the second magnet 7 will not collide with the cutter pad guide groove, greatly reducing the noise generated when the motor 4 drives the moving blade 2, so that the electric clipper has a mute effect when it is running; and because there is no contact friction, the friction loss in the kinetic energy transmission process can be reduced, and the efficiency can be improved.
[0066] In order to ensure the magnetic repulsion effect between the first magnet 6 and the second magnet 7, the opposite surfaces of the side walls 212 on both sides of the cutter pad 21 are provided with openings 2121 to expose the first magnet 6, reducing the shielding effect of the first magnet 6 in the side wall 212, and the second magnet 7 in the guide groove 211 has better repulsion (magnetic repulsion) with the adjacent first magnet 6.
[0067] As shown in the figure, Figure 5 and Figure 6 As shown in the figure, the bottom of the cutter pad 21 is also provided with a supporting pad 214, the supporting pad 214 is provided with a supporting portion 2141 corresponding to the insertion hole, the supporting portion 2141 is inserted into the insertion hole and abuts against the bottom of the first magnet 6. Preferably, the first magnet 6 is rectangular, and the supporting portion 2141 is provided with an inclined surface parallel to the side surface of the first magnet 6. When assembling the cutter pad 21, the first magnet 6 is first inserted into the side wall 212 of the guide groove 211 along the insertion hole in the bottom, and then the supporting portion 2141 of the supporting pad 214 is inserted into the insertion hole, so that the inclined surface of the supporting portion 2141 abuts against the first magnet 6, thereby pushing the first magnet 6 into the inside of the side wall 212 and firmly fixing it, effectively preventing the first magnet 6 from shaking in the inside of the side wall 212. Moreover, because the first magnet 6 is pushed into the inside of the side wall 212, the side wall 212 of the transmission portion near the second magnet 7 has sufficient magnetic force, and a better magnetic repulsion is generated between the side wall 212 and the annular magnet 72.
[0068] As can be seen from the figure, the rectangular magnet block (first magnet 6) in the side wall 212 is inclinedly placed in the cutter pad 21, which can make the transmission portion on the cutter pad 21 form a deeper slot, better place the annular magnet 72, and the first magnet 6 on both sides of the annular magnet 72 has a better force, so the stability of power transmission is higher.
[0069] In other optional embodiments, the first magnet is integrally formed with the cutter pad by using a plastic injection molding process. The first magnet is placed in a corresponding assembly position in a plastic mold of the cutter pad, and then the plastic mold is injection molded to form the first magnet and the cutter pad into one body. This way, the production efficiency is improved, and the assembly structure of the first magnet and the cutter pad is more stable.
[0070] As shown in Figure 3 In this embodiment, the magnetic silent electric clipper further includes a fixed base 5, the fixed blade 1 is fixedly connected with the fixed base 5, and the movable blade 2 is located between the fixed blade 1 and the fixed base 5. Specifically, the bottom of the fixed base 5 and the bottom end of the fixed blade 1 are provided with corresponding screw holes, and the second bolt 32 is installed and connected with the fixed base 5 and the fixed blade 1 through the screw holes. When assembling, the second bolt 32 connects the fixed blade 1 and the fixed base 5 from bottom to top, penetrates from one side of the fixed base 5, and then penetrates through the fixed blade 1 and is threadedly connected with the screw hole of the fixed blade 1.
[0071] As shown in Figure 7 The fixed base 5 is provided with a circular support plate 52, the circular support plate 52 is attached to the end face of the motor 4, and the circular support plate 52 and the end face of the motor 4 can be fixed by screwing to better provide stable support for the motor 4. The output shaft 41 of the motor 4 penetrates through the center hole 521 of the circular support plate 52 and is drivingly connected with the transmission part of the cutter pad 21 through the second magnet 7. The plate surface of the circular support plate 52 is provided with radial structural ribs to enhance the structural strength of the circular support plate 52.
[0072] The fixed base 5 is also provided with a hollow opening 51, and the guide groove 211 penetrates through the hollow opening 51 of the fixed base 5 and is linked with the motor 4 to obtain power. Therefore, the circular support plate 52 realizes stable power transmission between the motor 4 and the cutter assembly (the movable blade 2 and the fixed blade 1).
[0073] As shown in Figure 3 In this embodiment, the bottom of the movable blade 2 is provided with a guide block 22, and the fixed blade 1 is provided with a sliding groove 11 matched with the guide block 22; the guide block 22 slides in the sliding groove 11; and the guide block 22 and the sliding groove 11 enable the movable blade 2 to move back and forth on the fixed blade 1 along a defined trajectory.

The nuts are rectangular nuts, which are embedded into the nut grooves 221 of the guide block 22, and are fixed in the nut grooves 221. The first bolts 31 are fastened and connected with the nuts by screwing. The knife pad 21, the moving blade 2 and the guide block 22 are installed together by the nuts and the first bolts 31 to form an integral whole, thereby ensuring the structural stability of the moving blade 2. The bolt-nut detachable installation mode facilitates the disassembly and replacement of the moving blade 2.
[0075] Embodiment Two
[0076] The existing patent CN114633288A discloses an electric clipper head assembly. The fitting structure between the moving blade 2 and the fixed blade 1 is achieved by the elastic force of a torsion spring, which presses the moving blade 2 against the fixed blade 1. The contact part between the knife pad 21 of the moving blade 2 and the torsion spring is a very small contact surface, and the force receiving part is small. The pressure between the two contact rods of the torsion spring and the knife pad 21 is inconsistent due to the left-right dimensional tolerance of the torsion spring and the tolerance of the contact surface of the knife pad 21, which causes unstable stress of the blade during shearing movement and generates noise. Moreover, the contact part between the torsion spring and the knife pad 21 is prone to wear, which affects the service life.
[0077] As shown in Figure 5 and Figure 6 The magnetic silent electric clipper of the present embodiment can reduce the noise generated when the motor 4 drives the moving blade 2. The difference lies in that the fitting of the fixed blade 1 and the moving blade 2 is achieved by magnetic attraction instead of a torsion spring. The magnetic force makes the relative movement of the fixed blade 1 and the moving blade 2 stable and uniform, and further reduces the noise. Specifically, the magnetic silent electric clipper includes a fixed blade 1 and a moving blade 2. The moving blade 2 is provided with a third magnet 8, and the fixed blade 1 or its sliding groove 11 is made of metal. The third magnet 8 and the fixed blade 1 can be attracted to each other, so that the moving blade 2 is fitted to the fixed blade 1, thereby making the teeth of the moving blade 2 and the teeth of the fixed blade 1 fit together. The stress is stable during shearing movement, effectively reducing the noise generated during movement. Moreover, after long-term use, the fixed blade 1 and the moving blade 2 still maintain good fitting effect, which guarantees the shearing effect of the electric clipper.
[0078] In the embodiment, the guide block 22 is provided with a first accommodating groove 223, the groove bottom of the first accommodating groove 223 is hollow, the third magnet 8 is placed in the first accommodating groove 223, the first accommodating groove 223 supports the third magnet 8 above the sliding groove 11, the third magnet 8 is in a suspended state, a gap (about 0.2 mm) is left between the third magnet 8 and the sliding groove 11, and the third magnet 8 does not contact, so that only a small part of the guide block 22 is in contact with the sliding groove 11 during the sliding of the guide block 22 in the sliding groove 11, which helps to reduce the friction force of the moving blade 2 sliding on the fixed blade 1.
[0079] Embodiment three

This embodiment can also realize the upper and lower attachment of the teeth of the moving blade 2 and the teeth of the fixed blade 1, and the force on the moving blade 2 is more stable during the acquisition of kinetic energy, avoiding the noise caused by the wear between the contact surface of the torsional spring and the cutter pad 21, and further improving the mute effect.
[0081] The cutter pad 21 is provided with a second accommodating groove 213, and the fourth magnet 9 is placed in the second accommodating groove 213; the fixed base 5 is provided with a third magnet groove 54, and the fifth magnet 53 is placed in the third magnet groove 54.
