DETAILED DESCRIPTION

[0034] In order to facilitate the understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0035] Unless otherwise specified or defined, the "first, second..." used in this article is merely used to distinguish names and does not represent a specific quantity or order.

[0036] Unless specifically stated or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] It should be noted that when a component is considered to be "fixed to" another component, it can be directly fixed to the other component or there can be a central component; when an component is considered to be "connected to" another component, it can be directly connected to the other component or there can be a central component at the same time; when an component is considered to be "installed on" another component, it can be directly installed on the other component or there can be a central component at the same time. When an component is considered to be "set on" another component, it can be directly set on the other component or there can be a central component at the same time.

[0038] like Figures 1 to 6As shown, a cutter head mechanism 100 includes: a shell 10 and a cutter head assembly 20, wherein the shell 10 is provided with a mounting groove 11, and at least a portion of the cutter head assembly 20 is mounted in the mounting groove 11; the first end of the cutter head assembly 20 has a contact surface 40, and the contact surface 40 contacts the shell 10, and the second end of the cutter head assembly 20 has a shaving surface 30, and the shaving surface 30 is located on the opening of the mounting groove 11; wherein the shaving surface 30 and the contact surface 40 are arranged opposite to each other. By opening the mounting groove 11 on the housing 10, after the cutter head assembly 20 and the housing 10 are installed, the abutting surface 40 of the cutter head assembly 20 abuts against the housing 10, and the shaving surface 30 is located on the opening of the mounting groove 11, and the shaving surface 30 and the abutting surface 40 are arranged opposite to each other; during processing, it is only necessary to determine the depth of the mounting groove 11; after the cutter head assembly 20 is installed, the height of the shaving surface 30 on the housing 10 is determined according to the depth of the mounting groove 11; this slotting method does not need to consider the processing size of the limit block, Only the depth of the mounting groove 11 needs to be considered. The depth deviation of the mounting groove 11 is equal to the height deviation of the shaving surface 30. Therefore, this grooving method reduces the factors affecting the height deviation of the shaving surface 30. In actual processing, the uncertain factors are reduced, so that the height of the shaving surface 30 is within a controllable range. When in use, the cutter head assembly 20 is squeezed and pressed against the housing 10, and the shaving surface 30 of the cutter head assembly 20 is limited to a fixed height, thereby improving the problem of large deviation of the shaving surface 30 after the existing cutter head is installed.

[0039] like Figure 5 and Figure 6 The cutter head assembly 20 has a cutter holder 21 and at least two blades 22. The two blades 22 are mounted on the first end of the cutter holder 21. The second end of the cutter holder 21 is located in the mounting groove 11 and abuts against the housing 10. The two blades 22 are spaced apart. The blades 22 have blade edges 221. The ends of the two blade edges 221 form the shaving surface 30. When in use, the blade edges 221 of the blades 22 are in contact with the fitting surface, and the blade edges 221 are squeezed by the fitting surface. Since the blades 22 are mounted on the cutter holder 21 and the cutter holder 21 abuts against the housing 10, there is no space for the blades 22 to move, so the shaving surface is prevented from moving. The shaving surface is limited to a fixed height, which further improves the problem of large deviation of the shaving surface 30 after the existing cutter head is installed. In this embodiment, if the distance between the blade 221 and the fitting surface is too close, the skin may be easily cut, and if it is too far, the root of the beard cannot be shaved. Therefore, the height deviation of the shaving surface 30 is directly related to the distance between the blade 221 and the fitting surface.

[0040] like Figure 3 , Figure 4 as well as Figure 7As shown, the blade assembly 20 further comprises a first fastener 23 and a second fastener 24, the blade holder 21 comprises a slot 212, at least part of the blade 22 is located in the slot 212, the first fastener 23 is sleeved on the first end of the blade holder 21, the second fastener 24 is sleeved on the second end of the blade holder 21, and the first fastener 23 or the second fastener 24 is arranged close to the slot 212, and the first fastener 23 or the second fastener 24 is used to abut against the blade 22. By arranging the blade 22 in the slot 212, the first fastener 23 and the second fastener 24 are sleeved on the two ends of the blade holder 21 respectively, the first fastener 23 and the second fastener 24 are arranged close to the slot 212 and are located above the slot 212, so that the two ends of the blade 22 are restricted in the two slots 212 and abutted by the first fastener 23 and the second fastener 24 respectively, so that the blade 22 is prevented from coming out of the slot 212, and the stability of the blade 22 on the blade holder 21 is improved.

[0041] like Figure 7 and Figure 8 As shown, the blade holder 21 has a support block 211, and the blade 22 includes a main body 222 and a blade 221. The blade 221 and the main body 222 are an integrated structure, and an L-shaped groove 223 is formed between the blade 221 and the main body 222. The blade 22 is installed on the support block 211 through the L-shaped groove 223, and at least partially abuts against the support block 211. The blade 22 is installed on the support block 211 through the L-shaped groove 223. The support block 211 is used to support the blade 221, so as to provide a relatively stable supporting force for the blade 221 when the blade 221 abuts against the fitting surface; moreover, the blade 221 is supported by the support block 211, and the main body 222 is located in the avoidance groove 213 on the blade holder 21. The main body 222 is clamped on the blade holder 21 by the clamping groove 212, which further limits the movement of the blade 22 and improves the stability of the blade 22 on the blade holder 21.

[0042] like Figure 7 As shown, the cutter head assembly 20 has a buckle 26, and the housing 10 has a limiting groove 13, and the limiting groove 13 is connected to the mounting groove 11, so the buckle 26 cooperates with the limiting groove 13. During installation, the buckle 26 abuts against the inner wall of the mounting groove 11, and the buckle 26 is in a compressed state. When the barb of the buckle 26 enters the limiting groove 13, the buckle 26 returns to its original state, and the buckle 26 is limited in the mounting groove 11 by the limiting groove 13, thereby improving the stability of the cutter head assembly 20 in the mounting groove 11; moreover, the buckle 26 of the cutter head assembly 20 cooperates with the limiting groove 13, and the installation operation is also more convenient.

[0043] like Figure 1As shown, the cutter head assembly 20 also has a skin care fin 25 and a beard guide 27, both of which are extended along the width direction of the shaving surface 30, and the beard guide 27 is located between the shaving surface 30 and the skin care fin 25. The skin care fin 25 is generally made of elastic rubber material, which is multi-layered and soft. When the skin care fin 25 slides on the skin, the skin care fin 25 moves the beard on the skin and stands up the beard on the skin, making it easier for the outer wall of the beard to contact with the blade 221; the beard is first stood up by the skin care fin 25, and the beard guide 27 is used to further guide the beard and further stand up the beard. When the blade 221 of the shaving surface 30 contacts the standing beard, it is easier to cut off the beard, thereby completing the shaving operation.

[0044] like Fig. 9 As shown, the beard guide member 27 has a plurality of blocks 271, which are arranged in a width direction of the shaving surface 30, and a beard guide groove 272 is formed between two adjacent blocks 271. The beard guide groove 272 is formed between the adjacent blocks 271. When a plurality of beards pass through the beard guide groove 272, the plurality of blocks 271 are equivalent to combing the beards, so that the beards are arranged neatly, and are used to further make the beards stand upright. Most of the beards passing through the beard guide groove 272 can be cut off by the blade 221, thereby improving the shaving efficiency.

[0045] like Figure 2 As shown, the cutter head mechanism 100 further has a lubricating edge 12, which is wrapped on the outer wall of the housing 10 and extends along the circumference of the housing 10, and the lubricating edge 12 has a fitting surface, which is arranged toward the shaving surface 30. The lubricating edge 12 is used to cover the housing 10, and the fitting surface of the lubricating edge 12 is used to contact the skin. The friction force of the fitting surface is small, which reduces the friction force between the skin and the housing 10, thereby preventing the skin from being rubbed by the housing 10 during shaving, and improving the comfort of shaving.

[0046] like Figure 5 and Figure 6As shown, the cutter head mechanism 100 also has a mounting rod 14, which is mounted on the housing 10 and is arranged away from the shaving surface 30; this mounting rod 14 is used to connect to the mounting cavity on the handle 201 or the rotating mechanism 202, and the mounting rod 14 includes a first rod portion 141 and a second rod portion 142, the first end of the first rod portion 141 is mounted on the first end of the second rod portion 142, and an extrusion gap 143 is provided between the second end of the first rod portion 141 and the second end of the second rod portion 142. During installation, in order to make the installation rod 14 and the installation cavity have an interference fit, the width of the installation rod 14 is generally greater than the width of the installation cavity. In order to facilitate the installation rod 14 to be inserted into the installation cavity, an extrusion gap 143 is set between the first rod portion 141 and the second rod portion 142 of the installation rod 14. When the installation rod 14 is pushed into the installation cavity, the first rod portion 141 and the second rod portion 142 are close to each other, and the extrusion space becomes smaller. At the same time, the first rod portion 141 and the second rod portion 142 will apply a reverse force to the inner wall of the installation cavity, further improving the connection stability of the installation rod 14 after being inserted into the installation cavity. This extrusion gap 143 enables the installation rod 14 to have a telescopic function. When the installation rod 14 is separated from the installation cavity, the extrusion gap 143 returns to its original state.

[0047] like Fig.10 As shown, the utility model further provides a shaver 200, comprising a handle 201 and the cutter head mechanism 100 as described above, wherein the cutter head mechanism 100 is installed on a rotating mechanism 202 on the handle 201. The cutter head mechanism 100 is applied to the shaver 200 to reduce the height error of the shaving surface 30 after installation, and the shaving surface 30 of the shaver 200 cooperates with the fitting surface, so that the shaver 200 shaves the facial beard more cleanly, thereby improving the shaving efficiency of the shaver 200.

[0048] When quoting drawing descriptions, new features that appear are described; in order to avoid repeated quotations of drawings resulting in less concise descriptions, features that have been described clearly will not be quoted in the drawings one by one.
