DETAILED DESCRIPTION

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0026] In the description of the present invention, it should be understood that the terms "upper" and "lower" and the like indicate positions or location relationships that are based on the positions or location relationships when the product is in normal use.

[0027] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0028] The following is combined with Figure 1-6 This application is described in further detail.

[0029] The utility model embodiment provides a multifunctional automatic hair dryer, referring to Figure 1 and Figure 2The multifunctional self-service hair trimmer comprises a housing 1, a trimming head assembly 2 and a bald haircut assembly 3 movably mounted on the housing 1, and an adjusting wheel 4. The trimming head assembly 2 can trim long hair or trim long hair into short hair; the bald haircut assembly 3 can trim short hair into a bald hairstyle. The adjusting wheel 4 is rotatably connected to the bald haircut assembly 3 and the housing 1. When the adjusting wheel 4 rotates, the adjusting wheel 4 rotates relative to the housing 1 and drives the bald haircut assembly 3 to move. When trimming long hair or short hair, the adjusting wheel 4 is rotated to make the bald haircut assembly 3 move relative to the housing 1 and retract into the housing 1, and at this time, the bald haircut assembly 3 stops operating. When trimming short hair into a bald head, the adjusting wheel 4 is rotated to make the bald haircut assembly 3 move relative to the housing 1 and extend out of the housing 1, and at this time, the trimming head assembly 2 stops operating, so that the other set of blades will not form a secondary modification to the modified hairstyle, and at the same time, the other set of blades is not easy to scratch the scalp or skin of the user.

[0030] The overall shape of the shell 1 is similar to a flying saucer-shaped rotating body, which makes the appearance of the hair clipper more attractive. In addition, such a design also makes the trimming head assembly 2 and the bald hair cutting assembly 3 more compact inside the shell 1, thereby making the entire hair clipper smaller in size and easier to carry.

[0031] Reference Figure 1 and Figure 2 The housing 1 includes a first housing 11 and a second housing 12. An upper chamber is provided on a side of the first housing 11 close to the second housing 12, and a lower chamber connected to the upper chamber is provided on a side of the second housing 12 close to the first housing 11. When the housing 1 and the first housing 11 are buckled together, a complete installation cavity is formed, and the bald haircut assembly 3 is located in the installation cavity.

[0032] A cutter head opening 111 is provided on one side of the first shell 11 away from the second shell 12, and the cutter head opening 111 is communicated with the upper chamber. The bald hair cutting assembly 3 extends out from the installation cavity through the cutter head opening 111, and the trimming head assembly 2 is arranged at the cutter head opening 111, so that no matter what hairstyle is trimmed, there is no need to rotate the shell 1 to adjust the position of the cutter head. At the same time, the structure between the trimming head assembly 2 and the bald hair cutting assembly 3 is relatively compact.

[0033] Reference Figure 3 and Figure 4, a power supply 13 and a circuit board 14 are installed at the bottom of the lower chamber in the second housing 12. The power supply 13 and the circuit board 14 are electrically connected to each other. The power supply 13 is located on one side of the circuit board 14. The trimming cutter head assembly 2 and the hair clipper assembly 3 for bald heads are both electrically connected to the power supply 13 and the circuit board 14. The power supply 13 can provide electrical energy for the operation of the trimming cutter head assembly 2 and the hair clipper assembly 3 for bald heads. The circuit board 14 is used to control the distribution of electrical energy from the power supply 13 to the trimming cutter head assembly 2 or the hair clipper assembly 3 for bald heads, and thus control the independent operation of the trimming cutter head assembly 2 or the hair clipper assembly 3 for bald heads.

[0034] Refer to Figure 2 And Figure 3 , a circular arc-shaped groove 121 is provided on the outer wall of the second housing 12 on the side away from the first housing 11. When the user uses the hair clipper, the user can place the side of the housing 1 away from the cutter head opening 111 in the palm, and then the five fingers can be inserted into the circular arc-shaped groove 121 to achieve the holding and limiting of the hair clipper, thereby improving the comfort and stability when holding the hair clipper. In addition, the outer diameter of the second housing 12 on the side away from the first housing 11 is smaller than the outer diameter of the second housing 12 on the side close to the first housing 11. With such a design, people with smaller palms can also hold the hair clipper more easily.

[0035] Refer to Figure 3 And Figure 5 , the trimming cutter head assembly 2 includes a fixed cutter 21, a moving cutter 22, a moving cutter holder 23 and a trimming motor 24. The fixed cutter 21 is fixedly installed at the cutter head opening 111. The moving cutter 22 is also located at the cutter head opening 111 and abuts against the fixed cutter 21. The moving cutter 22 is installed on the moving cutter holder 23, and the moving cutter 22 and the moving cutter holder 23 can move synchronously. The trimming motor 24 is installed on the wall of the lower chamber and is electrically connected to the circuit board 14. An eccentric shaft is installed on the motor shaft of the trimming motor 24. A toggle lever 25 is also rotatably installed on the wall of the lower chamber. A driving groove for inserting the eccentric shaft is provided on the toggle lever 25, and a toggle hole 231 for inserting one end of the toggle lever 25 is provided on the cutter holder. When the trimming motor 24 operates, it will drive the eccentric shaft to rotate eccentrically. After the eccentric shaft rotates, it will drive the toggle lever 25 to swing under the action of the driving groove. Also, since one end of the toggle lever 25 is inserted into the toggle hole 231, the toggle lever 25 can drive the moving cutter holder 23 to drive the moving cutter 22 to swing reciprocally relative to the fixed cutter 21, thereby achieving the effect of trimming hair.

[0036] In another embodiment, both the trimming motor 24 and the toggle lever 25 can be installed in the upper chamber; in addition, the trimming motor 24 can be installed in the lower chamber and the toggle lever 25 can be installed in the upper chamber, and the specific situation depends on the spatial position in the installation chamber. In another way, the eccentric shaft can be directly inserted into the toggle hole 231 on the moving cutter holder 23 to drive the moving cutter holder 23 to move reciprocally.

[0037] Among them, in this embodiment, it is preferably determined that both the fixed blade 21 and the moving blade 22 are annular blades. On the one hand, the bald head hair trimming assembly 3 can pass through the fixed blade 21 and the moving blade 22, making the structure more compact; on the other hand, the trimming range is increased, thereby improving the efficiency of hair trimming.

[0038] Refer to Figure 5 , specifically, the cutter head opening 111 is also a circular opening. The outer peripheral wall of the fixed blade 21 abuts against the inner peripheral wall of the cutter head opening 111, and the fixed blade 21 is fixedly installed on the first housing 11. The inner peripheral wall of the fixed blade 21 gradually extends and bends along the axial direction of the fixed blade 21 itself towards the inside of the installation chamber. A plurality of fixed cutter teeth 211 are integrally formed at circumferential intervals on the inner peripheral wall of the fixed blade 21. Since the inner peripheral wall of the fixed blade 21 gradually extends and bends along its own axial direction towards the inside of the installation chamber, a certain distance is provided between the fixed cutter teeth 211 and the outer wall of the first housing 11 on the side where the cutter head opening 111 is opened. Therefore, when trimming short hair, the side of the first housing 11 where the cutter head opening 111 is opened can be directly attached to the scalp, and there is no need to worry about the risk of the fixed blade 21 and the moving blade 22 scratching the scalp during the entire trimming process.

[0039] A plurality of moving cutter teeth 221 are integrally formed at circumferential intervals on the inner peripheral wall of the moving blade 22 near one end close to the fixed blade 21. The plurality of fixed cutter teeth 211 are in abutting contact with each other, and the plurality of moving cutter teeth 221 and the plurality of fixed cutter teeth 211 are arranged in an interlaced manner, that is, there is a moving cutter tooth 221 between every two adjacent fixed cutter teeth 211. A trimming channel for hair to enter is formed between the fixed cutter teeth 211 and the moving cutter teeth 221. During trimming, the hair enters the trimming channel, and then is trimmed as the moving blade 22 swings to complete the trimming of the hair located in the trimming channel.

[0040] Refer to Figure 5 , one end of the moving blade 22 away from the fixed blade 21 is bent outward to form a flange 222. A plurality of docking posts 232 are integrally formed on one side of the moving blade holder 23 close to the flange 222, and the plurality of docking posts 232 are arranged at circumferential intervals on the moving blade holder 23. Docking grooves 223 with the same number as the docking posts 232 are formed on the flange 222. The plurality of docking posts 232 correspond to and are inserted into the corresponding docking grooves 223 one by one, so that the moving blade holder 23 can drive the moving blade 22 to move synchronously. In addition, when it is necessary to remove the moving blade 22 from the moving blade holder 23, since the moving blade 22 and the moving blade holder 23 are in a plug-in connection relationship, the outer shell 1 can be disassembled and then the moving blade 22 can be directly removed from the moving blade holder 23, making the disassembly of the moving blade 22 more convenient.

[0041] Refer to Figure 4 And Figure 5, on the cavity wall of the second housing 12, there is an integrally formed abutting post 122, and the abutting post 122 extends towards the first housing 11 but does not protrude from the second housing 12. The abutting post 122 is located below the moving tool holder 23 and is arranged at intervals with the moving tool holder 23. A driving spring 15 is placed between the abutting post 122 and the moving tool holder 23, and both ends of the driving spring 15 respectively abut against the moving tool holder 23 and the abutting post 122. The driving spring 15 always urges the moving tool holder 23 to have a tendency to approach the fixed blade 21, so that the fixed cutter teeth 211 and the moving cutter teeth 221 can be closely attached, thereby improving the trimming effect. Among them, on one side of the moving tool holder 23 close to the abutting post 122 and on one side of the abutting post 122 abutting against the moving tool holder 23, there are integrally formed sleeve posts respectively, and both ends of the driving spring 15 are respectively sleeved on the sleeve posts on the moving tool holder 23 and the abutting post 122, so that the driving spring 15 is not easily dropped during the shaking process of the moving tool holder 23. In another embodiment, the driving spring 15 can also be replaced with an elastic sheet or other elastic members having a certain elastic deformation ability.

[0042] In this embodiment, it is preferably that there are three abutting posts 122, and the three abutting posts 122 are circumferentially and evenly spaced within the second housing 12; similarly, there are also three driving springs 15, and the three driving springs 15 correspond to the three abutting posts 122 one by one, so that the moving tool holder 23 receives the elastic force of the driving spring 15 more evenly, and the elastic force received by the moving blade 22 and the fixed blade 21 after abutting is more even, further improving the trimming effect on hair.

[0043] Refer to Figure 3 And Figure 6 , the bald head haircut assembly 3 includes a tool holder sleeve 31, a bald head trimming cutter head 32, a cutter net cover 33 and a driving motor 34. One side of the tool holder sleeve 31 close to the cutter head opening 111 is open, the driving motor 34 is installed in the tool holder sleeve 31, the bald head trimming cutter head 32 is connected to the motor shaft of the driving motor 34, and the bald head trimming cutter head 32 rotates under the drive of the driving motor 34. The cutter net cover 33 is installed at the opening on one side of the tool holder sleeve 31 close to the cutter head opening 111, and the cutter net cover 33 covers the trimming cutter head, so that the trimming cutter head is not easily directly exposed to the air to scratch the user. In addition, hair can enter the inside of the cutter net cover 33 through the holes in the cutter net cover 33, and then the bald head trimming cutter head 32 and the cutter net cover 33 cooperate with each other to realize the trimming of hair. The tool holder sleeve 31 is in threaded cooperation with the adjusting wheel 4, and after rotating the adjusting wheel 4, it can drive the tool holder sleeve 31 to expand and contract, and the bald head trimming cutter head 32, the cutter net cover 33 and the driving motor 34 move and expand and contract synchronously with the tool holder sleeve 31.

[0044] Refer to Figure 5 And Figure 6A clamping plate 16 is integrally formed on one side of the first housing 11 close to the second housing 12. Two groups of clamping plates 16 are arranged circumferentially on the first housing 11. Both groups of clamping plates 16 can be inserted into the lower chamber and clamped on the wall of the lower chamber. The first housing 11 and the second housing 12 are spaced a certain distance apart by the clamping plates 16. The adjusting wheel 4 is located between the first housing 11 and the second housing 12 to fill the gap between the first housing 11 and the second housing 12.

[0045] Reference Figure 3 and Figure 6 The adjusting wheel 4 includes an adjusting outer ring 41, an adjusting inner ring 42 and a connecting plate 43. The adjusting outer ring 41 is sleeved on the adjusting inner ring 42. The adjusting outer ring 41 and the adjusting inner ring 42 are concentrically arranged, and there is a gap between the adjusting outer ring 41 and the adjusting inner ring 42 for the installation of the connecting plate 43. The connecting plate 43 extends along the radial direction of the adjusting appearance. The two ends of the connecting plate 43 respectively abut the inner wall of the adjusting outer ring 41 and the outer wall of the adjusting inner ring 42. The adjusting outer ring 41, the adjusting inner ring 42 and the connecting plate 43 are integrally formed. The adjusting outer ring 41 is sleeved on the two groups of clamping plates 16, and the connecting plate 43 can rotate between the two groups of clamping plates 16, and the rotation angle of the connecting plate 43 does not collide with the two groups of clamping plates 16 to form interference. Similarly, the connecting plate 43 does not interfere with the driving spring 15. The adjusting inner ring 42 is located in the installation cavity, and the adjusting inner ring 42 is sleeved on the tool holder sleeve 31 and is threadedly connected with the tool holder sleeve 31. When the tool holder sleeve 31 needs to be adjusted to be telescopic, the adjusting outer ring 41 is rotated, and the adjusting outer ring 41 rotates to drive the adjusting inner ring 42 to rotate, thereby driving the tool holder sleeve 31 to move axially to achieve telescopic movement.

[0046] Reference Figure 3 and Figure 4 The lower chamber of the second housing 12 is integrally formed with a plug sleeve 17, and one side of the tool holder sleeve 31 in the axial direction is inserted into the plug sleeve 17. A directional limit strip 311 is integrally formed on the outer peripheral wall of the tool holder sleeve 31, and an axial guide groove 171 is provided on the inner wall of the plug sleeve 17 for the directional limit strip 311 to be inserted and slided. When the inner ring 42 is adjusted to rotate, the tool holder sleeve 31 can move along its own axial direction to achieve expansion and contraction, rather than rotating synchronously with the adjustment inner ring 42.

[0047] It is worth noting that the movable knife holder 23 is sleeved on the adjusting inner ring 42, and a circle of abutting edges is integrally formed on the outer wall of the adjusting inner ring 42, and the movable knife holder 23 abuts on the abutting edges, so it is not easy to slide off the adjusting inner ring 42. In addition, the movable knife holder 23 and the adjusting inner ring 42 rotate relatively, so when the adjusting inner ring 42 is driven to rotate to make the knife seat sleeve 31 extend and retract, the movable knife holder 23 can remain relatively still under the action of the toggle rod 25.

[0048] The implementation principle of a multifunctional self-help hair clipper in an embodiment of the present application is as follows: when trimming long hair into short hair, rotate the adjustment outer ring 41. After the adjustment outer ring 41 rotates, it will drive the adjustment inner ring 42 to rotate. Since the cutter base sleeve 31 is threadedly connected to the adjustment inner ring 42, and at the same time, the directional limiting strip 311 is inserted into the axial guide groove 171, the bald head hair cutting assembly 3 will move along its own axial direction and contract in the installation cavity. Then, the circuit board 14 will control the trimming motor 24 to operate and drive the toggle lever 25 to drive the moving blade 22 to swing reciprocally, so that the moving blade 22 and the fixed blade 21 cooperate to complete the trimming of the hair.

[0049] Similarly, when trimming short hair into a bald head, rotate the adjustment outer ring 41 in the reverse direction to drive the bald head hair cutting assembly 3 to extend out of the installation cavity. The circuit board 14 controls the driving motor 34 to operate, so that the bald head trimming cutter head 32 and the cutter net cover 33 cooperate with each other to realize the trimming of the hair.

[0050] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will all fall within the protection scope of the present utility model.
