Detailed Implementation

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0033] Example 1:

[0034] See Figures 1-6 This embodiment provides a nose hair trimmer head, including a trimmer head body 101. The outer side of the trimmer head body has several slots 102. The trimmer head body 101 forms an internal cavity 103. A blade 104 is disposed in the internal cavity 103, its position matching the slots 102. A cleaning groove 106 communicating with the internal cavity 103 is also provided on the outer side of the trimmer head body. In this structure, the trimmer head body 101 forms a cavity structure, and the cleaning groove 106 is also provided, forming a hollow structure. This allows the trimmed nose hairs to be rinsed out in the cleaning groove 106 without disassembling the trimmer head body, making operation convenient, ensuring cleanliness, and preventing the accumulation of organic matter and grease that could lead to bacterial growth.

[0035] In this embodiment, an arc-shaped surface is specifically provided at the slot 102, and a plurality of arc-shaped grooves 107 are longitudinally spaced on the arc-shaped surface. The slot 102 is provided on the arc-shaped grooves 107. During the shaving process, the blade 104 forms a margin gap with the root of the nasal hair, so as not to damage the hair root and avoid skin scratches.

[0036] In this embodiment, a mounting groove is specifically provided within the internal cavity 103, and the blade 104 is adapted to fit within the mounting groove. Specifically, the mounting groove is composed of multiple sets of limiting parts, including:

[0037] The first limiting part is provided by the partition rib of the adjacent arc-shaped groove 107 that limits the internal cavity 103; 108

[0038] The second limit 109 and the third limit part 110 limit the upper and lower sides of the internal cavity 103;

[0039] And the fourth limiting part 111 that limits the rear side of the internal cavity 103.

[0040] The first limiting part and the second limiting part 109 are provided with a guide plane 112 for adapting to the cutting direction of the blade 104.

[0041] The cutter head body is composed of a first housing 113 and a second housing 114 assembled by a fixing structure 115.

[0042] Through the aforementioned limiting mechanism, the blade 104 can be stably positioned in the internal cavity 103, and the guide plane 112 causes the blade 104 to be inclined, making it more suitable for the cutting direction.

[0043] Specifically, in terms of the connection method, the fixing structure 115 adopts a snap-fit ​​structure, which consists of two sets of fasteners 116. The two sets of fasteners 116 are fastened together by the interacting inclined snap-fit ​​blocks 117.

[0044] The fastener 116 is provided with an elastic pressure block 118, which presses against the blade surface of the blade 104, so that the blade 104 can be more securely mounted on the mounting groove.

[0045] Two sets of fasteners 116 are perpendicular to the end face of the cleaning groove 106, and the cleaning groove 106 is isolated from the cleaning groove 106 by the vertical end face of the fasteners 116. Based on this structure, since the fasteners 116 are perpendicular to the cleaning groove 106, as shown in the figure, during the cutting process, the hair can be blocked and retained by the end face of the fasteners 116, and will not easily flow directly through the cleaning groove 106. This ingenious structural design allows the hair to be retained in the internal cavity 103 during use, so that the blade can be rinsed after operation, and the water flow can be used to clean it. Hair is flushed out of the cleaning tank 106 through the internal cavity. In this embodiment, the elastic pressure block 118 presses against the blade surface of the blade 104. The end face of the end piece of the elastic pressure block 118 is provided with a slot 119, so that during the rinsing process, the hair on the side of the cavity can be discharged more efficiently and quickly from the slot 119 through the rinsing tank. As shown in the figure, in order to allow for the connection between the upper and lower parts and the rinsing tank, the fastener 116 leaves a gap between the upper and lower ends and the upper and lower ends of the cavity. Therefore, the gap at the upper and lower ends also helps the hair to be flushed out quickly and efficiently during the rinsing process.

[0046] In this embodiment, the side of the cleaning tank 106 is also provided with a through-type secondary groove 120. The pressure space between the blade 104 and the limiting cavity is connected to the secondary groove 120. The blade 104 is provided with a guide hole. During use or rinsing, hair may accumulate in the gap between the blade 104 and the inner cavity wall (the pressure space between the blade 104 and the limiting cavity). It is not easy to flush out during rinsing. Therefore, in this structure, the side of the cleaning tank 106 is provided with a secondary groove 120 that is connected to the pressure space between the blade 104 and the limiting cavity. At the same time, the guide hole is provided based on the blade 104 so that the hair in the gap can be easily flushed out and will not accumulate.

[0047] In this embodiment, the blade body 101 is provided with a blade head 121 and a blade shank 122. The internal cavities 103 of the corresponding parts of the blade head 121 and the blade shank 122 are adapted to be provided with a snap-fit ​​structure, and a cleaning groove 106 is provided at the adapted position.

[0048] The first housing 113 and the second housing 114 are connected at their ends by a corrugated splicing structure 123, making the connection structure more stable during use. Specifically, in this embodiment, the first and second ends of the internal cavity 103 of the blade shank 122 are provided with positioning components. The positioning components include two sets of positioning modules. The positioning modules include a U-shaped groove block 124 and a plug-in block 125. The plug-in block 125 is adapted to be inserted into the U-shaped groove block 124. The two sets of positioning modules are plugged and adapted, so that the corresponding parts of the internal cavity 103 are relatively isolated. The hair in the upper cavity is not easy to fall into the internal cavity 103 of the blade shank 122. On the other hand, the blade shank 122 is also adapted to be provided with a cleaning groove 106 to prevent hair from entering the lower cavity through gaps, so that rinsing can still be performed. The blade head 121 is trapezoidal and tapered from the bottom to the top, which is used to better fit into the nasal cavity.

[0049] In this embodiment, the blades 104 of the cutter head body 101 are arranged in the same direction, which has a better cutting effect when the cutter head is in a fixed rotation direction. Therefore, the rotation direction can be marked on the cutter head body 101.

[0050] Example 2:

[0051] See Figures 1-7In this embodiment, due to the complex growth angle and interlacing of hair, rotation in one direction may result in some nasal hairs following the cutting direction of the blade, potentially causing incomplete cutting and missed areas. Therefore, in this embodiment, a set of blades 104 are symmetrically arranged at adjacent positions of the internal cavity 103, with the blades 104 tilted in opposite directions. Thus, in actual operation, by rotating the blade body 101 forward and backward, it can adapt to the complex growth trend of nasal hairs, allowing for a more thorough and clean cut. Furthermore, since the blades 104 are symmetrically arranged as shown in the figure, in the cutting state, the nasal hairs follow the cutting direction. As shown, the blades 104 can be mounted on either the first housing 113 or the second housing 114, with mounting grooves on both sides. To accommodate the installation of the improved first housing 113 and second housing 114, the fixing structure 115 includes a first fixing member and a second fixing member. Taking the blade 104 mounted on the first housing 113 as an example, both the first fixing member and the second fixing member have mounting grooves on their lower sides. The first fastener 116 is connected to both sides of the cleaning tank 106 in a U-shape. Elastic pressure blocks 118 are provided on both sides of the first fastener 116. A matching slot 119 is provided on the end face of the first fixing member behind the elastic pressure block 118. The top of the first fixing member and the top of the second fixing member are fixed by a connection structure such as an insertion (as shown in the figure of this embodiment, it is a concave-convex insertion structure; the specific fixing uses a snap-fit ​​structure at the rear end, as in the above embodiment, for further assembly and fixing), snap-fit, etc. In this structure, on one hand, the first housing 113... After the first and second fixing parts of the U-shaped housing 114 are assembled, they isolate the cleaning groove 106, making it difficult for the cut hair to be directly rotated out of the cleaning groove 106. Since the upper and lower sides of the first and second fixing parts need to reserve a certain space for more efficient rinsing out of the hair, the blades 104 are symmetrically arranged. After the hair is cut in the direction of rotation, the hair at the upper and lower ends can be blocked by the opposing blades 104, which to a certain extent prevents the hair from rotating out of the slot hole 102 of the arc groove 107.

[0052] Example 3:

[0053] Based on the above method, in this embodiment, a set of blades is symmetrically arranged at adjacent positions of the internal cavity to form a blade, as shown in the figure. It can also be set such that the blades are perpendicular to the slot opening plane and are set at the central axis position of the slot. The fixing structure for the splicing of the first shell and the second shell can also adopt the above-mentioned snap-fit ​​or plug-in method or other conventional connection method. This embodiment will not elaborate on it. In this case, both slots are open to the internal cavity, so that the hair has a better shaving effect and efficiency during forward and reverse rotation.

[0054] The above description is merely illustrative of the invention. Those skilled in the art can make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined by the claims, all of which should fall within the protection scope of this invention.
