Description

Technical Field

[0001] This utility model relates to the field of razor technology, specifically to a razor head for body hair. Background Technology

[0002] Body hair is a general term for hair on the human body, composed of layers of keratin scales. Some organisms experience seasonal changes in their body hair. Human body hair includes scalp hair, eyebrows, eyelashes, beard, chest hair, etc. Different organisms have different body hair types, and even within the same species, body hair color and growth rate vary. Some organisms' body hair serves different functions, such as insulation, detection, indirectly triggering tactile receptors, and camouflage. Razors are a common tool for shaving body hair. Razors generally come in three types: safety razors, electric razors, and manual razors. Razors are convenient to use, provide good shaving results, and are easy to carry, making them important for adult men's daily lives. The razor head is one of the most important components of a razor. A razor head generally includes razor blades and a blade housing for mounting the blades. The razor head is rotatably mounted on the razor handle, allowing it to rotate relative to the handle between a neutral position and a rotating position during use.

[0003] The common structure used to fix the blades in existing shaver heads is that the two ends of the blade are first inserted into through holes in the head frame, and then the two ends of the clamp are pushed outward with the help of a spreading tool, so that the clamp presses the shaver head assembled on the head frame. However, this structure is inconvenient for disassembling and maintaining the blade assembly inside the shaver head, and replacing the shaver head is time-consuming and laborious, making it inconvenient to use.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Please refer to Figures 1-5 This utility model provides a shaving head specifically for body hair, and the technical solution is as follows:

[0023] A shaver head for body hair includes a shaver head frame 1, a blade assembly 2 on the inner side of the shaver head frame 1, a rectangular through hole 3 in the middle of the blade assembly 2, a support plate 4 on the inner side of the rectangular through hole 3, a plurality of locking blocks 5 fixedly mounted on the upper end of the support plate 4, the locking blocks 5 being locked onto a connector 6 of the shaver body, the connector 6 having a locking groove 7, fixing sleeves 8 on both the left and right ends of the shaver head frame 1 via a connecting mechanism, and a top cover 23 fixedly mounted on the upper end of the shaver head frame 1.

[0024] In a preferred embodiment, a U-shaped component 9 is fixedly provided at the upper end of the blade assembly 2, and a guide limiting post 10 is fixedly provided at the middle position of the U-shaped component 9. The guide limiting post 10 is provided through the connector 6. The U-shaped component 9 is fixed on the blade assembly 2, which can improve the stability of the blade assembly 2.

[0025] In a preferred embodiment, pressure members 11 are fixedly provided at the four corners of the support plate 4. The pressure members 11 press on the blade assembly 2. Several guide grooves 12 are provided at both the front and rear ends of the blade frame 1. The blades on the blade assembly 2 match the guide grooves 12. The guide grooves 12 facilitate the removal of body hair using the blade assembly 2.

[0026] In a preferred embodiment, the connecting mechanism includes a support rod 13 slidably disposed on the side wall of the fixed sleeve 8. A limiting plate 14 is fixedly disposed on the side wall of the support rod 13. A spring 15 is disposed at the upper end of the limiting plate 14. Limiting protrusions 16 are fixedly disposed on both sides of the lower end of the support rod 13. An installation groove 17 is opened on the inner side wall of the bottom end of the fixed sleeve 8. An arc-shaped limiting groove 18 is provided at the bottom end of the installation groove 17. An installation hole 19 is opened at the end of the cutter head frame 1. A through hole 20 is opened on the side wall of the installation hole 19, and the through hole 20 matches the limiting protrusion 16. The top end of the support rod 13 penetrates the side wall of the upper cover 23 and is hinged to a limiting pull ring 21. A limiting column 22 is fixed at the top end of the upper cover 23.

[0027] In practical use, when the cutter head frame 1 is placed inside the fixed sleeve 8, the support rod 13 is lifted upward using the limiting pull ring 21. The support rod 13 can move downward under the action of the spring 15, so that the support rod 13 passes through the mounting hole 19 on the cutter head frame 1 and enters the mounting groove 17. Then, the support rod 13 is rotated so that the limiting protrusion 16 at the bottom of the support rod 13 enters the arc-shaped limiting groove 18, so that the support rod 13 cannot be pulled upward. Then, the limiting pull ring 21 is folded over and placed in the slot on the side wall of the limiting column 22, so that the limiting pull ring 21 cannot rotate, thereby limiting the support rod 13 in the horizontal direction.

[0028] The working principle of this utility model:

[0029] When installing the shaver head to the shaver body, the locking block 5 above the support plate 4 is inserted into the slot 7 on the connector 6 to install the shaver head. Disassembly is simple; just press the locking block 5 inwards and pull out the connector 6. The structure is simple and easy to operate. When installing the shaver head frame 1, use the limiting pull ring 21 to lift the support rod upwards, placing the shaver head frame 1 in the fixing sleeve 8. When the mounting hole 19 on the shaver head frame 1 aligns with the support rod 13, release the limiting pull ring 21. The support rod 13 moves downwards under the action of the spring 15, allowing the support rod 13 to pass through the mounting hole 19 on the shaver head frame 1, and the limiting protrusion 16 to pass through. The hole 20 enters the mounting groove 17. When the support rod 13 enters the bottom of the mounting groove 17, the support rod 13 is rotated, so that the limiting protrusion 16 enters the arc-shaped limiting groove 18. At this time, the spring 15 generates a certain torque, which folds the limiting pull ring 21 outward. One end of the limiting pull ring 21 is placed in the slot on the side wall of the limiting column 22. Due to the torque generated by the spring 15, the limiting pull ring 21 can be tightly attached to the limiting column 22, and the support rod 13 cannot rotate. When the support rod 13 cannot rotate, the limiting protrusion 16 cannot slide out of the arc-shaped limiting groove 18, and the support rod 13 cannot move upward, thus fixing the cutter head frame 1.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
