[0016] Please see Figure 1-5 This utility model provides a technical solution: a detachable and replaceable nose hair trimmer, including a nose hair trimmer body 1, an anti-slip sleeve 2 on the surface of the nose hair trimmer body 1, a trimmer head 3 on the top of the nose hair trimmer body 1, a connecting plate 4 fixedly connected to the bottom of the trimmer head 3, and an easy-to-disassemble device 5 on the top of the nose hair trimmer body 1.
[0017] The following section will explain the specific design and function of its easily detachable device 5.
[0018] In this embodiment: the easily detachable device 5 includes a limiting groove 51, which is opened at the top of the nose hair trimming body 1. A fixing block 59 is fixedly connected to the bottom of the connecting plate 4. Positioning blocks 52 are fixedly connected to both sides of the fixing block 59. Movable blocks 53 are movably connected to both sides inside the limiting groove 51. A positioning groove 54 is opened on one side of the movable block 53. The positioning block 52 is engaged inside the positioning groove 54.
[0019] Specifically, movable grooves 55 are provided on both sides of the top of the nose hair trimmer body 1 near the limiting groove 51, and a limiting spring 56 is fixedly connected to the side of the movable block 53 away from the positioning groove 54.
[0020] Specifically, the limiting spring 56 is fixedly connected to both sides of the inside of the limiting groove 51, and the sliding block 57 is movably connected inside the movable groove 55.
[0021] Specifically, the bottom of the sliding block 57 is fixedly connected to the top of the movable block 53, and a threaded rod 58 is provided inside the movable groove 55.
[0022] Specifically, the sliding block 57 is threadedly connected to the surface of the threaded rod 58, and a rotating rod 510 is fixedly connected to one side of the threaded rod 58.
[0023] Specifically, a rotating block 511 is fixedly connected to the side of the rotating rod 510 away from the threaded rod 58, and a retaining ring 512 is fixedly connected to the surface of the rotating rod 510.
[0024] Specifically, the retaining ring 512 is disposed on the outside of the nose hair trimming body 1, and the surface of the retaining ring 512 is provided with a fixing hole 513.
[0025] Specifically, the fixing hole 513 has several equally spaced holes on the surface of the retaining ring 512, and the fixing rod 514 is movably connected inside the fixing hole 513.
[0026] The effects achieved by the above components are as follows: By setting up the easy-to-disassemble device 5, the fixing rod 514 inside the fixing hole 513 can be rotated out, thus removing the restriction on the retaining ring 512. Then, the rotating block 511 drives the rotating rod 510 to rotate. During the rotation, the threaded rod 58 will rotate, thereby driving the sliding block 57 to move on the surface of the threaded rod 58, which will drive the movable block 53 to move at the same time. During the movement, the movable block 53 can be driven to move on both sides of the limiting groove 51 by the action of the limiting spring 56, thereby causing the positioning block 52 to move out inside the positioning groove 54. The fixing block 59 can then be disassembled inside the limiting groove 51, allowing for quick replacement of the trimmer head 3. The disassembly device can avoid disassembly difficulties caused by slippage. It can be operated by hand without the aid of tools, improving the adaptability of the scene. The nose hair trimmer needs to be cleaned regularly to avoid bacterial growth, which improves the cleanliness of the device. This improves the convenience of the device during use and increases the efficiency of the device.
[0027] Working principle: By incorporating the easy-to-disassemble device 5, when the trimmer head 3 needs to be replaced after a period of use, the fixing rod 514 inside the fixing hole 513 can be rotated out to release the restriction on the retaining ring 512. Then, the rotating block 511 drives the rotating rod 510 to rotate, which in turn drives the threaded rod 58 to rotate, thereby causing the sliding block 57 to move on the surface of the threaded rod 58, which in turn drives the movable block 53 to move simultaneously. During this movement, the movable block 53 is driven to move on both sides of the limiting groove 51 by the limiting spring 56, thereby causing the positioning block 52 to move out of the positioning groove 54. Finally, the fixing block 59 is moved out of the limiting groove 54. The internal parts of the slot 51 can be disassembled to allow for quick replacement of the trimmer head 3. The easy-to-disassemble device 5 reduces operational complexity, eliminating the need for users to deliberately align or exert force. Even people with weak hand strength can easily complete the disassembly, lowering the barrier to entry. In humid environments or when hands are wet or have skincare products on them, the easy-to-disassemble device 5 prevents disassembly difficulties caused by slippage. It can be operated by hand without tools, improving adaptability to different scenarios. Nasal hair trimmers require regular cleaning of the blade head to prevent bacterial growth. The easy-to-disassemble device 5 makes blade head disassembly more efficient, allowing users to quickly remove the blade head for washing and disinfection at any time, reducing the chance of neglecting cleaning due to the inconvenience of disassembly and lowering the risk of nasal infection.
