Description

[Technical Field]

[0001] This invention relates to an electric eyebrow trimmer head, and also to an electric eyebrow trimmer. [Background Technology]

[0002] Existing electric eyebrow trimmers, such as the one with announcement number CN306699538S, typically use front and rear plastic parts as supports to enclose and fix the moving and fixed blades from both sides, exposing only the cutting teeth of the moving and fixed blades. To improve cutting performance, the thickness of the cutting sections of the moving and fixed blades is usually made as thin as possible. However, because the cutting sections of the moving and fixed blades are relatively long, they must be sufficiently thick to ensure that the plastic has a certain structural strength and installation space, thus limiting further thinning. Currently, the thickness of products on the market is usually above 6mm.

[0003] This invention was made for this purpose. [Summary of the Invention]

[0004] The technical problem to be solved by the present invention is to provide an electric eyebrow trimmer head that has a simple structure, thin thickness, and good cutting performance.

[0005] An electric eyebrow trimmer head includes a support member, a fixed blade, and a moving blade. The support member and the fixed blade are fixed together front and back to form a rigid bracket. A sandwich space is formed between the support member and the fixed blade to allow the moving blade to reciprocate up and down. Corresponding cutting teeth are provided on the left and / or right sides of the fixed blade and the moving blade. The lower part of the bracket is provided with a mounting structure for connecting and fixing to a handle. The lower part of the moving blade is provided with a drive connection structure for connecting to a drive device.

[0006] As described above, in an electric eyebrow trimmer head, the support and the fixed blade are both made of rigid metal sheets.

[0007] As described above, in an electric eyebrow trimmer head, the support member and the fixed blade are welded and fixed; or the fixed blade and the support member are provided with support feet that abut together on the left and right sides, the fixed blade and the support member are provided with a through hole in the middle, and the fixed blade and the support member are provided with front and rear clamping plates that pass through the through hole and are fixed together on the outer side, and the front and rear clamping plates clamp and fix the fixed blade and the support member from the front and rear sides.

[0008] As described above, in an electric eyebrow trimmer head, when the support member and the fixed blade are welded and fixed, the support member and / or the fixed blade have a welding part recessed into the interlayer space in the middle, and the welding part has a welding hole that penetrates itself. The support member and the fixed blade are welded and fixed at the welding hole, and a decorative piece is fixed to the outside of the welding part to cover the welding hole; or the support member and the fixed blade abut against each other on the left and right sides of the interlayer space, and the support member and the fixed blade are welded and fixed at multiple abutment positions.

[0009] In the electric eyebrow trimmer head described above, when the fixed blade and the support are provided with front and rear clamping plates that pass through the through hole and are fixed together, the front and rear clamping plates are fixed by ultrasonic welding or by adhesive bonding.

[0010] As described above, in an electric eyebrow trimmer head, the clamping plate is provided with a guide portion that is inserted into the interlayer space, and the middle part of the moving blade is provided with a guide hole that is sleeved on the outside of the guide portion and slides up and down with the guide portion.

[0011] As described above, in an electric eyebrow trimmer head, the fixed blade and the support member have a recessed groove in the middle, and the front and rear clamping plates are respectively installed in the corresponding grooves.

[0012] As described above, in an electric eyebrow trimmer head, the fixed blade and the support member are respectively provided with outwardly arched portions located between the left and right support legs, and the groove, through hole and clamping piece are provided on the arched portions.

[0013] The electric eyebrow trimmer head described above has a thickness 'a' of less than 4 mm.

[0014] As described above, in an electric eyebrow trimmer head, the interlayer space is provided with a pressing member for pressing the moving blade against the inner side of the fixed blade.

[0015] Another technical problem to be solved by the present invention is to provide an electric eyebrow trimmer with a simple structure, thin blade, and good cutting performance.

[0016] An electric eyebrow trimmer using the above-mentioned blade includes a handle. The lower end of the bracket is connected and fixed to the upper part of the handle through a mounting structure. The handle is provided with a drive device, which is connected to the moving blade through a drive connection structure and is used to drive the moving blade to reciprocate up and down.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. The blade of the present invention forms an external support by combining the fixed blade and the support member at the front and back. By reserving a space between the blades, the moving blade can reciprocate inside. This avoids the structure of using front and rear plastic parts as supports to enclose the moving blade and the fixed blade inside, thus making the blade thinner and better for eyebrow shaping.

[0019] 2. The support and the fixed blade are made of rigid metal sheets, which have good structural strength and are more conducive to reducing the thickness of the blade.

[0020] 3. The fixed blade and support member have support feet on their left and right sides that abut together. A through hole is provided in the middle of the fixed blade and support member. Front and rear clamping plates pass through the through hole and are fixed together on the outer sides of the fixed blade and support member. The front and rear clamping plates clamp and fix the fixed blade and support member from the front and rear sides. The structure is simple and helps reduce the thickness of the bracket. Furthermore, the front and rear clamping plates are fixed by ultrasonic welding or by adhesive bonding, which helps reduce the installation space required between the front and rear clamping plates and effectively reduces the thickness of the bracket. In particular, the fixed blade and support member have concave grooves in their middle. The front and rear clamping plates are respectively installed in the corresponding grooves, reducing the height of the clamping plates protruding from the fixed blade and support member, reducing the impact of the clamping plates on the overall blade volume, and avoiding affecting cutting performance.

[0021] 4. The support member and / or the fixed blade are provided with a welded part that is recessed into the interlayer space in the middle. The welded part is provided with a welded hole that penetrates itself. The support member and the fixed blade are fixed by welding at the welded hole. Welding through the welded hole avoids the weld point from protruding significantly from the welded part. A decorative piece is fixed to the outside of the welded part to cover the welded hole. The decorative piece is fixed to the recessed welded part by pasting to avoid the weld point being exposed and easily corroded or coming into contact with the skin, thus avoiding affecting the user experience.

Detailed Implementation Methods

[0032] The present invention will now be further described with reference to the accompanying drawings:

[0033] like Figures 1 to 6 The illustrated electric eyebrow trimmer head includes a support member 1, a fixed blade 2, and a moving blade 3. The support member 1 and the fixed blade 2 are fixed together front to back to form a rigid bracket 10. A cavity 101 is formed between the support member 1 and the fixed blade 2 to allow the moving blade 3 to reciprocate up and down within it. The lower part of the bracket 10 has a mounting structure 102 for connecting and fixing to a handle, and the lower end of the moving blade 3 has a drive connection structure 31 for connecting to a drive device. This trimmer head, with the fixed blade 2 and support member 1 combined front to back to form an external bracket 10, and with the reserved cavity 101 allowing the moving blade 3 to reciprocate inside, avoids the need for a structure using front and rear plastic parts as a bracket to enclose the moving and fixed blades inside, thus allowing for a thinner trimmer head for better eyebrow shaping. Figure 7 and Figure 8 As shown, the bracket 10 is mounted on the handle 6 via the lower mounting structure 102, and the upper middle part of the blade stands above the handle 6 and is used for trimming hair.

[0034] The fixed blade 2 and the moving blade 3 are provided with corresponding cutting teeth 2a on their left and right sides. Since the support 10 can be made very thin, the cutting teeth 2a on both sides have good cutting performance. Of course, the corresponding cutting teeth 2a can also be provided only on the left or right side of the fixed blade 2 and the moving blade 3. When the fixed blade 2 and the moving blade 3 are provided with cutting teeth 2a on their left and right sides respectively, the structure of the cutting teeth 2a on both sides is one large and one small. The larger side has higher trimming efficiency and is conducive to quick trimming for rough trimming, while the smaller side is conducive to fine trimming.

[0035] The thickness 'a' of the cutter head is less than 4 mm. Preferably, the support 1 and the fixed blade 2 are made of rigid metal sheets, which helps to reduce the thickness of the cutter head, and the thickness of its bracket 10 is less than 3 mm.

[0036] like Figures 2 to 5 In the illustrated embodiment, to ensure the moving blade 3 adheres more stably to its inner side and improves trimming sharpness, the interlayer space 101 is provided with a pressing member 5 for pressing the moving blade 3 against the inner side of the fixed blade 2. Preferably, the pressing member 5 is made of metal sheet and has a pressing structure that arches towards the moving blade 3 and elastically presses against it. Of course, the pressing member 5 can also be a ribbed structure made of plastic.

[0037] like Figures 1 to 9 The embodiment shown is one implementation of the installation structure. The installation structure 102 includes locking feet 109 and locking grooves 110 disposed on the left and right sides of the support member 1 and the fixed blade 2, and buckle holes 111 disposed on the support member 1 and the fixed blade 2.

[0038] like Figures 1 to 3 The embodiments shown in 6 and 7 are one implementation of the drive connection structure. The drive connection structure 31 includes a connection hole provided on the moving blade 3 and a reinforcement member 8 fixed on the moving blade 3 to reinforce the connection hole. The reinforcement member 8 increases the thickness and strength at the connection hole of the moving blade 3, and also helps the moving blade 3 to have a thinner thickness.

[0039] As a way of fixing support 1 and fixed tool 2, such as Figure 1 and 2 In the illustrated embodiment, the fixed blade 2 and the support member 1 have support feet 105 abutting together on their left and right sides. A through hole 106 is provided in the middle of the fixed blade 2 and the support member 1. Front and rear clamping plates 4 are provided on the outer sides of the fixed blade 2 and the support member 1, passing through the through hole 106 and fixed together. The front and rear clamping plates 4 clamp and fix the fixed blade 2 and the support member 1 from the front and rear sides. The structure is simple and helps to reduce the thickness t of the bracket 10. Only a very small thickness, such as less than 2mm, is needed to meet the structural requirements of the front and rear clamping plates 4 and the space required for installation. The height h of the clamping plates 4 protruding from the outer side of the fixed blade 2 or the support member 1 is less than 0.5mm to avoid affecting the cutting angle of the blade when the clamping plates 4 press against the skin during cutting.

[0040] Preferably, the front and rear clamping pieces 4 are fixed together by ultrasonic welding or by adhesive bonding. This simple structure helps to reduce the installation space required between the front and rear clamping pieces 4 and effectively reduces the thickness of the bracket 10.

[0041] Preferably, the fixed blade 2 and the support member 1 are provided with a concave groove 107 in the middle, and the front and rear clamping pieces 4 are respectively installed in the corresponding grooves 107, thereby reducing the height of the clamping pieces 4 protruding from the fixed blade 2 and the support member 1, reducing the impact of the clamping pieces 4 on the overall blade volume, and avoiding its impact on cutting performance.

[0042] Furthermore, the fixed blade 2 and the support member 1 are respectively provided with arched portions 108 that arch outward on the inner side of the left and right support feet 105. The arched portions 108 form a sandwich space 101. The groove 107, through hole 106 and clamping piece 4 are provided on the arched portions 108, which not only ensures that the front and rear clamping pieces 4 have sufficient installation space, but also facilitates the installation of the top pressing member 5 in the sandwich space 101, and also helps the bracket 10 to have a smaller thickness.

[0043] The clamping piece 4 is provided with a guide part 41 that is inserted into the interlayer space 101, and the middle part of the moving knife 3 is provided with a guide hole 32 that is sleeved on the outside of the guide part 41 and slides up and down to guide the guide part 41.

[0044] As a second method of fixing the support 1 and the fixed tool 2, such as Figure 5 In the illustrated embodiment, the support member 1 and the fixed blade 2 have a recessed welding portion 103 in the middle of the interlayer space 101. The welding portion 103 has a through welding hole 104. The support member 1 and the fixed blade 2 are fixed by welding at the welding hole 104. Welding through the welding hole 104 avoids the weld point from protruding significantly from the welding portion 103. A decorative piece 9 is fixed to the outside of the welding portion 103 to cover the welding hole 104. The decorative piece is glued to the recessed welding portion 103 to prevent the weld point from being exposed, easily corroded, or coming into contact with the skin, thus avoiding affecting the user experience. Of course, the welding portion 103 can also be provided only on the support member 1 or the fixed blade 2. The thickness t of the bracket 10 formed by the support member 1 and the fixed blade 2 is less than 2mm, and the height h of the decorative piece protruding from the outside of the fixed blade 2 or the support member 1 is less than 0.5mm.

[0045] As a third way of fixing support 1 and fixed tool 2, such as Figure 6 In the embodiment shown, the support member 1 and the fixed blade 2 abut against each other on the left and right sides of the interlayer space 101, and the support member 1 and the fixed blade 2 are spot welded and fixed at multiple abutment positions.

[0046] like Figures 7 to 9 An electric eyebrow trimmer is shown, including a handle 6. The lower end of the bracket 10 is connected and fixed to the upper part of the handle 6 through the mounting structure 102. Specifically, the handle 6 has front and rear shells. The front and rear shells are provided with locking positions and bone positions that cooperate with the locking feet 109 and the locking grooves 110, as well as locking posts in the locking holes 111 on the support member 1 and the fixed blade 2. The structure is simple and the installation stability is good.

[0047] The handle 6 is equipped with a drive device 7, which is connected to the moving blade 3 through a drive connection structure 31 and is used to drive the moving blade 3 to reciprocate up and down.

[0048] like Figure 7The driving device 7 includes a swing member 71 hinged to the inside of the handle 6. A connecting rod 72 is provided between the swing member 71 and the moving blade 3, which can drive the moving blade 3 to move up and down reciprocally when the swing member 71 swings. One end of the connecting rod 72 is rotatably connected to the swing member 71, and the other end is rotatably connected to the moving blade 3. A drive motor 73 is provided inside the handle 6. An eccentric shaft 74 is connected to the output shaft of the drive motor 73. The swing member 71 is provided with a mating groove 711 that cooperates with the eccentric shaft 74 and swings with the eccentric rotation of the eccentric shaft 74. The structure is simple.
