Description

Technical Field

[0001] This utility model relates to the field of nose hair trimmers, and more specifically to a nose hair trimmer. Background Technology

[0002] In existing nose hair trimmer designs, the battery is typically located below the motor. While this layout simplifies the internal structure and makes the overall design more compact, it introduces several problems in practical use.

[0033] Furthermore, in the description of this application, the terms "first," "second," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance. It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.

[0034] refer to Figures 1 to 3 This utility model provides a nose hair trimmer, including a fixed bracket 1, a blade assembly 2, a drive assembly 3, a control assembly 4, and a battery assembly 5. The fixed bracket 1 has a receiving cavity and has a length direction 101 and a width direction 102. The drive assembly 3 and the battery assembly 5 are spaced apart in the receiving cavity along the length direction 101. The drive assembly 3 is adapted to connect to the blade assembly 2. The control assembly 4 is disposed on one side of the fixed bracket 1 in the width direction 102.

[0035] In this embodiment, the fixed bracket 1 is provided with the drive component 3 and the battery component 5 at intervals along its length direction 101. By increasing the bottom area of ​​the fixed bracket 1, the center of gravity distribution of the drive component 3 and the battery component 5 is balanced, thereby improving the stability of the nose hair trimmer. The control component 4 is provided on one side of the fixed bracket 1 in the width direction 102, which facilitates operation, improves the grip experience, and prevents slippage.

[0036] Specifically, the fixed bracket 1 is the main structure of the trimmer, with an internal cavity for accommodating the drive assembly 3 and the battery assembly 5. The fixed bracket 1 has a length direction 101 and a width direction 102. The drive assembly 3 and the battery assembly 5 are spaced apart along the length direction 101 within the cavity. This layout optimizes the use of internal space. Furthermore, the spaced arrangement of the drive assembly 3 and battery assembly 5 along the length direction 101 increases the bottom area of ​​the fixed bracket 1, balancing the center of gravity distribution of the drive assembly 3 and battery assembly 5. This not only lowers the overall center of gravity of the nose hair trimmer, bringing it closer to the bottom, thus significantly improving the stability of the nose hair trimmer, but also effectively reduces wobbling or tipping during use due to instability. In addition, the wider bottom design provides a larger support surface for the nose hair trimmer, further enhancing its stability in various placement environments. Whether placed on a table or other flat surface, it remains stable and is less prone to slipping. More specifically, this application cleverly balances the center of gravity distribution of the drive assembly 3 and battery assembly 5, making the center of gravity of the nose hair trimmer lower and closer to the bottom of the trimmer. This optimized center of gravity not only effectively reduces the risk of the trimmer tipping over during placement or use, but also provides users with a more stable grip, enhancing the overall reliability of the nose hair trimmer.

[0037] refer to Figure 1 and Figure 6 The control component 4 is located on one side of the fixed bracket 1 in the width direction 102, facilitating user operation during use. Users can easily control the trimmer's on / off function, speed adjustment, and other functions without frequently adjusting their grip. The control component 4 typically includes a button, switch, or touch-sensitive area, offering simple operation and rapid response. In practical use, users can easily touch the control component 4 with their fingers to perform functions such as power on / off and speed adjustment without adjusting their grip or overextending their fingers, thus improving ease of use and comfort. Furthermore, this design, through reasonable weight distribution and optimized hand contact surface, further enhances the nose hair trimmer's anti-slip performance, allowing users to hold the trimmer more firmly during use, reducing accidents caused by hand slippage, and improving overall safety and reliability.

[0038] Further, refer to Figure 4 and Figure 5 The fixing bracket 1 includes a first bracket 11, which includes a first fixing part 111 and a second fixing part 112 spaced apart along the length direction 101. The top of the first fixing part 111 is provided with a drive channel 1111. The drive assembly 3 is disposed in the first fixing part 111, and the top of the drive assembly 3 is adapted to pass through the drive channel 1111 and coaxially connect to the cutter head assembly 2. The battery assembly 5 is disposed in the second fixing part 112. The fixing bracket 1 also includes a second bracket 12 adapted to connect the first bracket 11. The second bracket 12 includes a third fixing part 121 and a fourth fixing part 122. The third fixing part 121 and the first fixing part 111 are adapted to fix the drive assembly 3, and the fourth fixing part 122 and the second fixing part 112 are adapted to fix the battery assembly 5.

[0039] In this embodiment, the first bracket 11 and the second bracket 12 are connected vertically and the drive assembly 3 is fixed between the first fixing part 111 and the third fixing part 121. The battery assembly 5 is fixed between the second fixing part 112 and the fourth fixing part 122. The structure achieves a balance between compactness and stability, which not only improves the overall performance of the product, but also provides users with a safer and more reliable user experience.

[0040] Specifically, the drive assembly 3 is fixed between the first fixing part 111 of the first bracket 11 and the third fixing part 121 of the second bracket 12, ensuring the stability of the drive assembly 3 during operation, reducing the impact of vibration on the trimming effect, and also helping to extend the service life of the drive assembly 3. Meanwhile, the battery assembly 5 is fixed between the second fixing part 112 of the first bracket 11 and the fourth fixing part 122 of the second bracket 12. The relatively low position of the battery assembly 5 helps to lower the overall center of gravity of the product, thereby improving the stability of the nose hair trimmer. Furthermore, this layout also facilitates heat dissipation and charging of the battery assembly 5. Heat dissipation vents are provided on both sides of the width direction 102 of both the second fixing part 112 and the fourth fixing part 122.

[0041] Furthermore, the bottom of the third fixing part 121 is higher than the bottom of the fourth fixing part 122. The second bracket 12 also includes a fifth fixing part 123. The fifth fixing part 123 is disposed below the third fixing part 121 and the bottom of the fifth fixing part 123 is flush with the bottom of the fourth fixing part 122. A charging component 1231 is provided inside the fifth fixing part 123. The charging component 1231 is located below the drive component 3.

[0042] In this embodiment, the bottom of the third fixing part 121 is higher than the bottom of the fourth fixing part 122, so that the position of the driving component 3 is relatively high and the position of the battery component 5 is relatively low. Through this height difference, the center of gravity of the nose hair trimmer is effectively lowered, thereby improving the overall stability.

[0043] Specifically, the fixing bracket 1 consists of a first bracket 11 and a second bracket 12. The second bracket 12 has a third fixing part 121, a fourth fixing part 122, and a fifth fixing part 123. The third fixing part 121 cooperates with the first fixing part 111 to fix the drive assembly 3; the fourth fixing part 122 cooperates with the second fixing part 112 to fix the battery assembly 5. The bottom of the third fixing part 121 is higher than the fourth fixing part 122 to optimize the center of gravity distribution. The fifth fixing part 123 is located below the third fixing part 121, and its bottom is flush with the fourth fixing part 122. The fifth fixing part 123 houses the charging assembly 1231, placing the charging assembly 1231 below the drive assembly 3. This design, through the rational layout of the components, lowers the center of gravity of the nose hair trimmer, improves overall stability, and optimizes the utilization of internal space.

[0044] It is worth noting that the drive component 3 is fixed at a relatively high position, while the battery component 5 is fixed at a relatively low position. Since the battery component 5 is typically heavier than the drive component 3, placing it at a lower position significantly lowers the overall center of gravity of the product. This design not only makes the nose hair trimmer more stable when placed, reducing the risk of tipping over, but also provides better balance during use, enhancing the user's grip experience. This high-low layout not only cleverly balances the weight distribution of the components but also optimizes the utilization of internal space, allowing the nose hair trimmer to maintain a compact size while possessing greater stability and better performance. Furthermore, by placing the drive component 3 at a higher position, more space is provided for the heat dissipation and charging of the battery component 5. The second bracket 12 also includes a fifth fixing part 123, which is located below the third fixing part 121. The bottom of the fifth fixing part 123 is flush with the bottom of the fourth fixing part 122. This design further balances the product's center of gravity distribution, making the overall structure more stable and further improving the product's performance and lifespan.

[0045] Further, refer to Figure 1 , Figure 4 and Figure 5 The control component 4 includes a circuit board 41. A first snap-fit ​​member 13 is provided on the outer side of the top of the fixed bracket 1, and a second snap-fit ​​member 14 is provided on the outer side of the bottom of the fixed bracket 1. The circuit board 41 is snap-fitted between the first snap-fit ​​member 13 and the second snap-fit ​​member 14 and is located on one side of the battery component 5 in the width direction 102.

[0046] In this embodiment, the circuit board 41 is snapped between the first snap-fit ​​member 13 and the second snap-fit ​​member 14, which enables the circuit board 41 to be securely installed and easily disassembled. The circuit board 41 is located on one side of the battery assembly 5 in the width direction 102. This layout not only provides sufficient space for the circuit board 41 to avoid interference with the battery assembly 5, but also facilitates the electrical connection between the circuit board 41, the battery assembly 5, and the drive assembly 3.

[0047] Specifically, the mounting bracket 1 has a first snap-fit ​​member 13 on its top outer side and a second snap-fit ​​member 14 on its bottom outer side. The circuit board 41 is installed between the first snap-fit ​​member 13 and the second snap-fit ​​member 14 via a snap-fit ​​method, forming a stable fixing structure, realizing the secure installation and convenient disassembly of the circuit board 41. In addition, the position design of the circuit board 41 has also been carefully planned, and it is located on one side of the battery assembly 5 in the width direction 102. This layout not only provides sufficient space for the circuit board 41 to avoid interference with the battery assembly 5, but also facilitates the electrical connection between the circuit board 41 and the battery assembly 5 and other control components. Through this snap-fit ​​installation method, the replacement and maintenance of the circuit board 41 becomes more convenient, and at the same time, it improves the overall reliability and maintainability of the product.

[0048] Preferably, refer to Figure 6 The control component 4 also includes a control switch 42, which is mounted on the circuit board 41 and positioned relative to the center of the fixed bracket 1 along its length 101. In this embodiment, placing the control switch 42 at the center of the fixed bracket 1 along its length 101 allows the user to easily reach the control switch 42 with their thumb or forefinger while holding the nose hair trimmer, enabling operation without adjusting the grip posture, thus improving ease of use and comfort. The central position design of the control switch 42 not only optimizes the operating experience but also makes the overall structure of the product more balanced. This layout avoids instability caused by switch position offset, further enhancing the stability of the product.

[0049] Further, refer to Figure 3 and Figure 7 It also includes a housing 6, which includes a first housing 61 and a second housing 62. The first housing 61 is adapted to cover the top opening of the second housing 62. The fixing bracket 1 is adapted to be disposed inside the housing 6. The first housing 61 is provided with a first channel 611, the bottom of the second housing 62 is provided with a second channel 621, and the side wall of the second housing 62 is provided with a third channel 622. The first channel 611 is adapted to allow the drive component 3 to pass through, the second channel 621 is adapted to allow the charging component 1231 to pass through, and the third channel 622 is adapted to allow the control switch 42 to pass through.

[0050] Specifically, the first channel 611 is located on the first housing 61 and is used to ensure that the drive assembly 3 can be connected to the external cutter head assembly 2 and work normally through the connection part of the drive assembly 3 (such as a motor shaft or transmission shaft). The second channel 621 is located at the bottom of the second housing 62 and is used to facilitate the user to charge the battery assembly 5 through the connection part of the charging assembly 1231 (such as a charging interface or charging cable). The third channel 622 is located on the side wall of the second housing 62 and is used to allow the user to operate the control assembly 4 from the outside through the control switch 42 to realize functions such as power on / off and speed adjustment. The first housing 61 is also provided with a mounting hole, which is suitable for installing the extraction part 612, and the extraction part 612 is suitable for lifting the outer shell 6. Through the extraction part 612, the user can easily lift the entire outer shell 6, thereby facilitating the carrying and use of the product. This design not only improves the user experience, but also makes the movement and operation of the outer shell 6 more convenient. It also includes a sealing ring 15, and a placement position is provided on the top side wall of the fixing bracket 1. The sealing ring 15 is placed in the placement position and abuts against the inner side wall of the second housing 62. This sealing design effectively prevents external contaminants from entering the housing 6, affecting the normal operation of internal components, protecting them from damage, and also contributing to improved overall product durability. Furthermore, it includes a cover sleeve 21, which is magnetically attached to the outside of the cutter head assembly 2. The cover sleeve 21 uses a magnetic design, allowing it to firmly adhere to the outside of the cutter head assembly 2. This magnetic attachment not only ensures the stable fixation of the cover sleeve 21 but also facilitates quick installation and removal by the user, improving ease of use. Of course, there are various ways to remove the cover sleeve 21, which will not be elaborated further here.

[0051] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
