[0021] Compared with the prior art, the beneficial effects of the present invention are: this multifunctional electric hair clipper;

[0022] 1. This multifunctional electric hair clipper is provided with a rotating blade. By using the rotation of the rotating blade, external air flow enters the upper shell and the lower shell through the air inlet slot holes and is discharged from the air outlet slot holes. The flowing air flow is used to take out the heat inside the electric hair clipper, avoiding the situation of a large amount of heat accumulation inside it.

The upper housing 2 is arranged on the top of the lower housing 1, and a limiting comb 3 is arranged on the side of the upper housing 2; further including:

[0040] An air intake slot hole 4 is opened on the side of the upper housing 2, and an air outlet slot hole 5 is arranged on one side of the air intake slot hole 4;

[0041] The drive motor 6 is installed inside the lower housing 1, and a rotating shaft rod 7 is provided at the output end of the drive motor 6. A rotating blade 8 is provided on the outer wall of the rotating shaft rod 7, and a worm wheel disc 9 is provided on the side of the rotating blade 8. A connecting through hole 10 is opened inside the worm wheel disc 9, and a pressing column 11 is provided on the outer wall of the worm wheel disc 9. A docking mechanism 12 is provided on the side of the pressing column 11. The docking mechanism 12 includes a docking seat 1201 and a first airbag 1202. The first airbag 1202 is provided inside the docking seat 1201, and an air guide pipe 14 is communicated with the side of the first airbag 1202;

[0042] The eccentric wheel 17 is provided at the end of the rotating shaft rod 7. An eccentric shaft 18 is provided on the outer wall of the eccentric wheel 17, and a connecting seat 19 is connected to the side of the eccentric shaft 18. A limiting piece 23 is provided inside the connecting seat 19, and a fixing seat 24 is provided at the end of the limiting piece 23;

[0043] The docking piece 25 is provided at the bottom of the fixing seat 24. A cutting blade 38 is provided on the side of the docking piece 25, and a positioning tooth piece 37 is provided on the side of the cutting blade 38. At the same time, a blade housing 36 is provided outside the positioning tooth piece 37;

[0044] The connecting through holes 10 are arranged at equal angles with respect to the worm wheel disc 9. A limiting column 13 is fixedly connected to the left outer wall of the worm wheel disc 9, and a docking worm 15 is provided at the bottom of the worm wheel disc 9. The docking mechanism 12 further includes a movable block 1203 and a movable rod 1204. The movable block 1203 is provided on the side of the first airbag 1202, and the outer surface of the movable block 1203 is mutually attached to the outer surface of the first airbag 1202. A movable rod 1204 is provided at the end of the movable block 1203, and the outer surface of the movable rod 1204 is mutually attached to the outer surface of the pressing column 11. The pressing column 11 is embedded inside the docking seat 1201, and the outer shape of the docking seat 1201 is arranged in an arc-shaped structure. At the same time, there is a gap between the docking seat 1201 and the worm wheel disc 9, and the docking seat 1201 is fixedly connected to the lower housing 1. An adjusting disc 16 is provided at the end of the docking worm 15, and the docking worm 15 is movably connected to the lower housing 1, and one side of the adjusting disc 16 is exposed;

[0045] First, by controlling the rotation of the drive motor 6 inside the lower housing 1, the drive motor 6 drives the rotation of the rotating shaft rod 7. The rotating blade 8 provided on the outer wall of the rotating shaft rod 7 uses the rotation of the rotating blade 8 to accelerate the flow of air inside the lower housing 1. Grooves (as shown in Figure 11 shown) for gas flow are provided on both sides of the drive motor 6, which facilitates the entry of external gas through the intake slot holes 4, flows through the grooves on both sides of the drive motor 6, and flows out through the outlet slot holes 5. Using the flowing air, the heat generated by the operation of the drive motor 6 is taken out to achieve the effect of cooling the internal components;

[0046] And when it is necessary to let the gas inside the lower housing 1 enter the inside of the blade housing 36, by rotating the adjustment disk 16, the adjustment disk 16 drives the docking worm 15 to rotate inside the lower housing 1, and when the docking worm 15 rotates, it drives the worm wheel disk 9 to rotate. A plurality of connecting through holes 10 are formed on the worm wheel disk 9, and the aperture on the connecting through hole 10 is communicated with the preset aperture on the lower housing 1 (as Figure 11 shown), so that part of the air flow enters the inside of the blade housing 36 through the connecting through hole 10, and the flowing air flow is used to automatically blow the broken hair at the blade housing 36 and the cutting blade 38, achieving the effect of automatically cleaning the broken hair. When only dissipating heat from the drive motor 6, the connecting through hole 10 on the worm wheel disk 9 is staggered with the preset slot on the lower housing 1, so as to block the channel through which the connecting through hole 10 flows to the blade housing 36, achieving the effect of a single heat dissipation mode.

[0047] Embodiment 2

[0048] This embodiment aims to promote the solution of the problem of how to achieve the short-term lifting of the cutting blade 38 and the positioning tooth piece 37. This embodiment is an improvement based on Embodiment 1. Specifically, please refer to Figures 3 to 8 , a second airbag 20 is arranged inside the connecting seat 19, and the second airbag 20 is communicated with the first airbag 1202 through an air guide pipe 14. A sliding block 21 is attached to the side of the second airbag 20. At the same time, a first spring 22 is arranged on the side of the sliding block 21, and the sliding block 21 is fixedly connected to the limiting piece 23. The bottom of the positioning seat 33 is fixedly connected to the blade housing 36, and there is a gap between the blade housing 36 and the cutting blade 38. The cutting blade 38 is sleeved outside the docking piece 25. A docking block 39 is arranged on the outer wall of the docking piece 25, and the docking block 39 is embedded inside the positioning tooth piece 37;

[0049] When the worm wheel disc 9 rotates, the worm wheel disc 9 drives the pressing column 11 to slide inside the docking seat 1201, enabling the pressing column 11 to extrude the movable rod 1204 and the movable block 1203 arranged inside the docking seat 1201. When the movable block 1203 moves downward, it compresses the first airbag 1202, causing the gas inside the first airbag 1202 to enter the interior of the second airbag 20 through the air guide pipe 14, and making the second airbag 20 expand. When the second airbag 20 expands, it drives the sliding block 21 and the limiting piece 23 to slide inside the connecting seat 19, and compresses the first spring 22, enabling the limiting piece 23 to be embedded inside the fixed seat 24. When the driving motor 6 drives the rotating shaft rod 7 to rotate, the rotating shaft rod 7 drives the eccentric shaft 18 on the eccentric wheel 17 to rotate. When the eccentric shaft 18 rotates, the eccentric shaft 18 contacts the limiting piece 23 and presses against it, causing the limiting piece 23, the connecting seat 19, and the fixed seat 24 to move upward. When the fixed seat 24 moves upward, it drives the docking piece 25 and the cutting blade 38 to move upward, realizing a brief separation between the cutting blade 38 and the positioning tooth piece 37, facilitating the gas flowing into the blade housing 36 to blow between the cutting blade 38 and the positioning tooth piece 37, and facilitating the cleaning of the broken hair clamped between the cutting blade 38 and the positioning tooth piece 37, improving the cleaning effect;

[0050] When the worm wheel disc 9 moves in the reset motion, the extrusion of the first airbag 1202 is released. At this time, the first spring 22 drives the sliding block 21 and the limiting piece 23 to reset, enabling the limiting piece 23 to be embedded inside the connecting seat 19. As the worm wheel disc 9 rotates in the reset, when the limiting column 13 on the worm wheel disc 9 contacts one side of the docking seat 1201, it reaches the reset position. At this time, the connecting through hole 10 on the worm wheel disc 9 intersects with the preset through hole on the lower housing 1, blocking the channel for the gas flowing into the blade housing 36. When the rotating shaft rod 7 drives the eccentric shaft 18 on the eccentric wheel 17 to rotate, when the eccentric shaft 18 rotates, it drives the docking piece 25 and the cutting blade 38 to slide left and right on the positioning tooth piece 37. And a docking block 39 is arranged on the cutting blade 38. When the cutting blade 38 slides, it drives the docking block 39 to slide left and right inside the positioning tooth piece 37. And a preset lifting distance is provided at the connection between the docking block 39 and the positioning tooth piece 37, facilitating its brief lifting to achieve the shearing effect on the hair without affecting its normal use.

[0051] Embodiment 3

[0052] The intention of this embodiment is to promote the solution to the problem of how to reduce the separation force between the cutting blade 38 and the positioning tooth piece 37. This embodiment is an improvement based on Embodiment 1. Specifically, please refer to Figures 7 to 10, an electric push rod 26 is arranged on the inner side of the docking piece 25, and a push plate 27 is arranged at the output end of the electric push rod 26. A conical block 28 is connected to the end of the push plate 27. At the same time, a docking column 29 is arranged on the outer wall of the conical block 28. A second spring 30 is arranged on the outside of the docking column 29, and the second spring 30 is welded to the conical block 28. A torsion spring 31 is arranged on the side of the conical block 28. The torsion spring 31 includes a spring connecting rod 3101, a spring coil 3102 and a spring positioning rod 3103. The spring connecting rod 3101 is welded to the conical block 28. The end of the spring connecting rod 3101 is connected to the spring coil 3102. A spring positioning rod 3103 is arranged at the end of the spring coil 3102. At the same time, a positioning piece 32 is arranged on the outside of the spring positioning rod 3103. A positioning seat 33 is arranged on the outer wall of the positioning piece 32. Limiting rods 34 are arranged on both sides of the positioning seat 33. A connecting disc 35 is arranged at the end of the limiting rod 34. At the same time, the limiting rod 34 penetrates through the inside of the spring coil 3102;

[0053] Torsion springs 31 are arranged on both side surfaces of the docking piece 25. The spring positioning rod 3103 of the torsion spring 31 is connected to the positioning piece 32. The spring coil 3102 of the torsion spring 31 is embedded outside the limiting rod 34 on the positioning seat 33 to realize the positioning of the position of the torsion spring 31. By using the setting of the torsion spring 31, a downward pressure is applied to one side of the docking piece 25, so that the cutting blade 38 is attached to the positioning tooth piece 37. When the docking piece 25 on the cutting blade 38 slides left and right, the spring coil 3102 can be driven to slide on the limiting rod 34 at the same time. A sliding distance is reserved on the limiting rod 34. When it is necessary to adjust the downward pressure of the torsion spring 31 on the docking piece 25, the electric push rod 26 on the docking piece 25 is controlled to move. The electric push rod 26 drives the push plate 27 to slide inside the docking piece 25. The end of the push plate 27 is inclined and connected to the conical block 28. When the push plate 27 moves, the push plate 27 will squeeze the conical block 28. At this time, the conical block 28 and the docking column 29 will be driven to move, and the second spring 30 will be compressed, and the spring connecting rod 3101 will move inward, realizing the reduction of the extrusion force of the torsion spring 31 on the docking piece 25, and making the force required for the cutting blade 38 to separate from the positioning tooth piece 37 smaller. By changing the position of the spring connecting rod 3101 relative to the docking piece 25, the effect of multi-functional adjustment of the downward pressure is achieved.
