[0035] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0036] This utility model discloses a nose hair trimmer; please refer to [link / reference]. Figures 1 to 9 ,include:

[0037] The handle housing 1 has an open top structure;

[0038] Mounting plate 2 is detachably connected to handle housing 1 and blocks the upper opening of handle housing 1. Mounting plate 2 has a first mounting position 211, a second mounting position 221 and a third mounting position 231. The first mounting position 211 and the third mounting position 231 are both opened on the inner side of mounting plate 2, and the second mounting position 221 is opened on the outer side of mounting plate 2 and communicates with the first mounting position 211.

[0039] Motor 3, which is detachably mounted at the first mounting position 211;

[0040] The cutter head 4 is rotatably mounted in the second mounting position 221 and is connected to the drive end of the motor 3.

[0041] Battery 5 is detachably mounted in the third mounting position 231 and electrically connected to motor 3.

[0042] During installation, first install the motor 3 onto the first mounting position 211 of the mounting plate 2, rotate and install the blade 4 onto the second mounting position 221 of the mounting plate 2, and install the battery 5 onto the third mounting position 231 of the mounting plate 2. Then, install the mounting plate 2 onto the handle housing 1, thus achieving quick installation of the entire nose hair remover. That is, by setting up a single mounting plate 2, the motor 3, blade 4, and battery 5 are all mounted on the same mounting plate 2, which can easily accommodate handle housings 1 of different shapes. It is only necessary to ensure that the mounting plate 2 is installed on the handle housing 1. This improves upon the problem in existing nose hair removers where the motor 3, blade 4, and battery 5 are installed independently, making it impossible to adapt to different shapes of handle housings 1 and meet the usage needs of different types of users.

[0043] Based on the above embodiment, the outer edge of the mounting plate 2 is an upward and inward inclined slope structure, and is covered with a protective cover 26 to protect the blade head 4, achieving the effect of dust prevention and hygiene. When using the device, the user only needs to remove the protective cover 26.

[0044] The blade 4 is a conventional technique in this field and is not the inventive point of this utility model, so its specific structure will not be described in detail here.

[0045] Please see Figures 3 to 9 The nose hair remover of this utility model has a central column 21 fixedly connected to the inner side of the mounting plate 2. One end of the central column 21 is away from the opening of the mounting plate 2 to form a first mounting position 211, and the motor 3 is mounted on the central column 21.

[0046] In this invention, one end of the central column 21 opens downwards away from the mounting plate 2 to form a first mounting position 211. When installing the motor 3, inserting the motor 3 into the lower opening end of the central column 21 allows the motor 3 to be installed in the first mounting position 211, thus completing the installation. (See also: [link to invention description]). Figure 7 and Figure 8 The lower opening end of the central column 21 is laterally open to form a lateral opening structure. When the motor 3 is inserted into the first mounting position 211, the lower opening end of the central column 21 can undergo adaptive deformation to clamp the motor 3, thereby ensuring the stable installation of the motor 3. The central column 21 can be made of plastic.

[0047] One end of the central column 21 is shown as Figure 3 The lower end of the central column 21.

[0048] The nose hair remover of this utility model has a support plate 11 fixedly connected inside the handle housing 1, which is opposite to the central column 21, and the support plate 11 is supported by the motor 3.

[0049] When the mounting plate 2 with the motor 3 installed is installed on the handle housing 1, the motor 3 enters the opening of the handle housing 1. When the mounting plate 2 seals the opening of the handle housing 1, the tail end of the motor 3 abuts against the support plate 11, so as to support the motor 3 through the support plate 11 and ensure that the motor 3 is stably installed in the first mounting position 211 of the center column 21.

[0050] Furthermore, multiple side limiting plates are fixedly connected inside the handle housing 1. These side limiting plates are distributed in a circular pattern. When the central column 21 enters the opening of the handle housing 1, one side of the central column 21 abuts against the inner side of the multiple side limiting plates, thereby limiting the central column 21 through the side limiting plates and ensuring that the central column 21 can only move vertically.

[0051] Please see Figure 3 and Figure 5 In this utility model, a support ring 22 is fixedly connected to the outer side of the mounting plate 2. The other end of the central column 21 is open and connected to the support ring 22 to form a second mounting position 221. The support ring 22 is overlapped with a first sealing ring 222 and is detachably connected with a cover ring 223. The cover ring 223 is pressed against the first sealing ring 222. The blade head 4 is rotatably connected to the first sealing ring 222.

[0052] Specifically, the support ring 22 is a ring-shaped structure with a vertical through opening. Its lower end is coaxially fixed to the upper side of the mounting plate 2 and communicates with the upper opening end of the support ring 22. The bottom of the upper opening of the support ring 22 is through to form a middle hole and communicates with its lower opening so that the motor 3 can be installed in the first mounting position 211 of the central column 21. The output end of the motor 3 is connected to the cutter head 4 through the middle hole using the transmission component installed in the upper opening of the support ring 22. The cutter head 4 is inserted into the support ring 22 and then inserted downward into the upper opening of the support ring 22 to connect with the output end of the motor 3.

[0053] The first sealing ring 222 is coaxially disposed with the support ring 22, and its upper end is folded outward to form an overlapping part, which overlaps the upper side of the support ring 22. The lower end of the first sealing ring 222 is folded inward to form an inwardly folded part. After the cutter head 4 is inserted into the support ring 22 and connected to the output end of the motor 3, the blade of the cutter head 4 is inserted into the support ring 22 and abuts against the inwardly folded part of the first sealing ring 222. At the same time, the blade of the cutter head 4 is rotatably connected to the support ring 22, and the blade of the cutter head 4 is coaxially and fixedly connected to the rotating frame of the cutter head 4.

[0054] The lower end of the cover ring 223 is detachably connected to the outside of the support ring 22, and its upper end is folded inward to form a pressing part. After the cutter head 4 is installed, the cover ring 223 is inserted from the cutting part of the cutter head 4 and placed on the outside of the support ring 22. At the same time, the cover ring 223 is detachably connected to the support ring 22. After the cover ring 223 is installed in place, the pressing part of the cover ring 223 presses down on the overlapping part of the first sealing ring 222 to ensure stable installation.

[0055] During use, the blade of the cutter head 4 abuts against the inner part of the first sealing ring 222 and against the inner side of the first sealing ring 222 to form a sealing effect, thereby reducing the entry of impurities such as nose hair and dust.

[0056] The other end of the central column 21 is shown as Figure 3 The upper end of the central column 21. The cover ring 223 can be connected and installed with the support ring 22 by means of threaded connection, or by means of snap-fit.

[0057] Please see Figure 7 and Figure 8 In this utility model of nose hair remover, multiple first elastic clamps 23 are fixedly connected to the inner side of the mounting plate 2. Each first elastic clamp 23 forms a third mounting position 231 with the central column 21. The battery 5 is simultaneously pressed and pressed against the central column 21 by each first elastic clamp 23.

[0058] In this invention, each of the first elastic clamping plates 23 forms an opening structure with its opening facing downward away from the mounting plate 2 between itself and the central post 21, thus forming a third mounting position 231. When installing the battery 5 in the third mounting position 231 of the mounting plate 2, the battery 5 is directly inserted into the third mounting position 231, and the first elastic clamping plates 23 apply pressure to the battery 5, so that the battery 5 is pressed tightly against the outside of the central post 21, thus completing the stable installation of the battery 5.

[0059] The first elastic clamp 23 can be made of plastic and is integrally formed with the mounting plate 2. Specifically, two first elastic clamps 23 are provided, spaced apart, with their opposite ends bent towards the central post 21 to form an arc shape. This allows the two first elastic clamps 23 to simultaneously cover the battery 5 when pressing it down, ensuring stable installation of the battery 5.

[0060] Please see Figure 3 and Figure 4 The nose hair remover of this utility model has multiple support columns 12 fixedly connected inside the handle housing 1, and multiple fastening holes 24 are opened through the mounting plate 2. Each fastening hole 24 is inserted with a fastening screw 6, and each fastening screw 6 is threaded to each support column 12.

[0061] Each support post 12 has an upward opening structure and is provided with internal threads. Each fastening hole 24 is a countersunk hole, corresponding one-to-one with the upward opening of each support post 12. When installing the mounting plate 2 onto the handle housing 1, each fastening screw 6 is inserted into each fastening hole 24 and threadedly connected to the corresponding support post 12, thereby achieving a stable installation between the mounting plate 2 and the handle housing 1.

[0062] Please see Figures 3 to 9 In this utility model of nose hair remover, a pressure ring 25 is fixedly connected to the inner edge of the mounting plate 2, and a second sealing ring 7 is pressed between the pressure ring 25 and the inner wall of the handle housing 1.

[0063] Before installing the mounting plate 2 onto the handle housing 1, the second sealing ring 7 is first fixed to the outside of the pressure ring 25 of the mounting plate 2, or fixed to the inner wall of the corresponding position of the handle housing 1. Then, the mounting plate 2 is installed onto the handle housing 1. The second sealing ring 7 is squeezed and deformed by the handle housing 1 and the pressure ring 25 to fill the handle housing 1 and the mounting plate 2, thereby achieving a sealed installation.

[0064] The second sealing ring 7 can be made of rubber. Based on the above embodiment, a first protruding ring is fixedly connected to the outer side of the second sealing ring 7, and a first groove is provided at the corresponding position on the handle housing 1. The second sealing ring 7 can be installed on the inner wall of the handle housing 1 by inserting the first protruding ring into the first groove, and then the mounting plate 2 can be installed on the handle housing 1. Simultaneously, the insertion of the first protruding ring into the first groove also improves the sealing effect of the second sealing ring 7. As a parallel solution, the second sealing ring 7 can also be fixed to the outer side of the pressure ring 25 by adhesive bonding, and then the mounting plate 2 can be installed on the handle housing 1.

[0065] Please see Figure 3 , Figure 4 , Figure 8 as well as Figure 9 In this utility model of nose hair clipper, each fastening hole 24 is provided with at least two second elastic clamping plates 241 at intervals. Each second elastic clamping plate 241 is fixedly connected to the inner side of the mounting plate 2. The second sealing ring 7 is fixedly connected with multiple support parts 71. Each support part 71 corresponds to each fastening hole 24 and is clamped between the corresponding second elastic clamping plates 241. Each support part 71 is clamped between the corresponding support column 12 and the mounting plate 2.

[0066] Each support part 71 has a through hole for the corresponding fastening screw 6 to pass through.

[0067] When the second sealing ring 7 is installed on the inner wall of the handle housing 1, each support post 12 is supported on the lower side of the corresponding support part 71 to ensure the stability of the second sealing ring 7 under the support of each support post 12. Each second elastic clamping plate 241 corresponding to each fastening hole 24 has a downward opening structure, so that the upper end of the support post 12 fits into and extends into the lower opening of the corresponding second elastic clamping plate 241 and abuts against the inner side of the corresponding second elastic clamping plate 241 to further ensure the installation stability of the second sealing ring 7.

[0068] When the support 71 is clamped between the corresponding second elastic clamps 241, the clamping of the second elastic clamps 241 can be used to improve the connection structure strength between the support 71 and the second sealing ring 7 and the mounting plate 2, and prevent the second sealing ring 7 from detaching from the mounting plate 2.

[0069] When the mounting plate 2 is installed on the handle housing 1, each support part 71 is clamped between the corresponding support post 12 and the mounting plate 2. The support part 71 forms a sealing structure between the support post 12 and the mounting plate 2 to reduce the probability of external water entering the nose hair trimmer through the fastening hole 24, thereby improving the waterproof effect.

[0070] In this invention, the fastening holes 24, the support columns 12, and the support parts 71 can each be two, three, four, or five, etc. The figures show two of each.

[0071] Please see Figures 5 to 9 The nose hair remover of this utility model also includes a switch 8 and a main board 81 electrically connected to the switch 8. The main board 81 is detachably connected to the handle housing 1 and electrically connected to the motor 3. A pressing hole 13 is provided through the side wall of the handle housing 1. The switch 8 is detachably connected to the pressing hole 13. A sealing plate 72 is fixedly connected to the second sealing ring 7. The sealing plate 72 abuts against the inner side of the handle housing 1 and seals the pressing hole 13. The switch 8 and the main board 81 abut against the two sides of the sealing plate 72 respectively.

[0072] When in use, press switch 8, and the main board 81 will start motor 3, causing the blade head 4 to rotate and trim nose hairs. Switch 8 is secured to the handle housing 1 by a single-sided latch.

[0073] In this invention, two opposing open third elastic clamping plates 27 are fixed on the inner side of the mounting plate 2, and the two ends of the main board 81 are respectively inserted into the openings of the two third elastic clamping plates 27 to achieve installation.

[0074] After the mounting plate 2 is installed on the handle housing 1, one side of the sealing plate 72 of the second sealing ring 7 seals the inner opening of the press hole 13, while the main board 81 abuts against the other side of the sealing plate 72. Then, the switch 8 is installed in the press hole 13, and the switch 8 is pressed against one side of the sealing plate 72. When the switch 8 is pressed, the switch 8 controls the main board 81 via an electrical signal, and the main board 81 sends a command to start the motor 3. During this process, the sealing plate 72 remains pressed against the inner side of the handle housing 1, forming a seal against the inner opening of the press hole 13, thus reducing the entry of external water and impurities.

[0075] Based on the above embodiments, the sealing plate 72 is fixedly connected with a second protruding ring, which abuts against the inner side of the handle housing 1 to improve the sealing effect.

[0076] Please see Figure 3 , Figure 4 ,as well as Figures 7 to 9 The nose hair remover of this utility model also includes a charging port 9 and a charging circuit board 91 electrically connected to the charging port 9. The charging circuit board 91 is detachably connected to the handle housing 1 and electrically connected to the main board 81 and the battery 5. A charging port 14 is provided through the side wall of the handle housing 1. One end of the charging port 9 is connected to the charging port 14 and abuts against the inner side of the handle housing 1, and the other end is fixedly connected to the charging circuit board 91.

[0077] When charging, connect the charging port 9 to the power source, and the charging circuit board 91 stores electrical energy in the battery 5. Pressing the switch 8 controls the main board 81 via an electrical signal. The main board 81 then sends a command to start the motor 3, which drives the blade head 4 to rotate and trim nose hairs.

[0078] The charging port 9 can be fixed to the inner wall of the handle housing 1 with sealant. The charging port 9 is preferably a Type-C interface. The Type-C interface is a symmetrical interface, eliminating the need to consider alignment during insertion, solving the problem of inaccurate insertion with USB interfaces, and enabling blind insertion, which is especially convenient for use at night or in low-light environments. Of course, depending on cost or the needs of specific application groups, the charging port 9 can also be a standard USB interface.

[0079] In this invention, two opposing fourth elastic clamping plates 28 are fixed on the inner side of the mounting plate 2, and the two ends of the charging circuit board 91 are respectively inserted into the openings of the two fourth elastic clamping plates 28 to achieve installation.

[0080] Based on the above embodiment, a third sealing ring 92 is provided on the outside of the charging port 9, with its two ends abutting against the inner side of the handle housing 1 and the charging circuit board 91, respectively. In use, the third sealing ring 92 covers the charging port 9 to prevent water from seeping into the gap at the charging port 9.

[0081] Furthermore, a second groove is provided on the inner side of the handle housing 1, and a third convex ring that fits and is inserted into the second groove is fixedly connected to one end of the third sealing ring 92, so as to further improve the sealing effect by inserting the third convex ring into the second groove.

[0082] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
