[Specific implementation method]

[0034] The technical features of the present invention are further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can understand. The directions such as up, down, left and right described in the text are consistent with the directions shown in the drawings of the specification.

[0035] A nose hair shaving head that is easy to clean, such as Figures 1 to 11As shown, it comprises an outer shell 1, a static knife 3 is provided at the top of the outer shell 1, a movable knife 5 is rotatably provided in the static knife 3, the outer wall of the movable knife 5 is in contact with the inner wall of the static knife 3, a blade 7 is provided at the top of the static knife 3, a plug 8 is provided in the movable knife 5 for preventing broken hair debris from falling into the deep inside of the knife head, a storage cavity 9 for centrally accommodating broken hair debris is formed between the blade 7 and the plug 8, a transmission assembly 11 for driving the movable knife 5 to rotate is provided in the outer shell 1 and below the movable knife 5, and a transmission assembly 11 for driving the movable knife 5 to rotate is provided in the transmission assembly 11. A bottom cover 2 fixedly connected to the outer shell 1 is provided at the bottom of the component 11. The above structure can collect broken hair debris in the storage cavity 9 when the nose hair shaving head is used to shave nose hair. The plug 8 can effectively prevent the broken hair debris from falling into the deep of the cutter head. When cleaning, it is only necessary to rinse the static cutter part of the nose hair shaving head. The broken hair debris can be cleaned without disassembling the cutter head. The cleaning process is simple and convenient. At the same time, since the outer wall of the movable cutter 5 is in contact with the inner wall of the static cutter 3, hair can be prevented from being clamped, thereby improving the user experience. The first embodiment of the nose hair shaving head is as follows: Figure 1 to Figure 7 As shown, the second embodiment Figure 8 to Figure 11 shown.

[0036] Specifically, the static knife 3 includes a plurality of static knife teeth 4 arranged at equal intervals, and a protective head 25 is provided at one end of the static knife 3 located at the blade 7. The protective head 25 is a structure bent inwardly toward the blade 7, which can eliminate the edges of the static knife 3 in contact with the nasal cavity and prevent the static knife 3 from stinging or scratching the nasal cavity, so as to improve the user experience. A plurality of dynamic knife teeth 6 with inclined edges are provided at the top of the dynamic knife 5, and the static knife teeth 4 form a shearing angle with the edges of the dynamic knife teeth 6. The inclined static knife teeth 4 can effectively guide the nose hair from the blade 7 into between the static knife teeth 4 for shearing, and the scissor-like shearing angle can quickly cut the nose hair, thereby effectively improving the shearing efficiency.

Figure 3 to Figure 7As shown, in the first embodiment of the nose hair shaving head, a concave ring 26 is provided in the middle section of the outer wall of the movable blade 5, and the concave ring 26 can reduce the contact area between the outer wall of the movable blade 5 and the inner wall of the stationary blade 3, so as to reduce the rotational friction between the movable blade 5 and the stationary blade 3, so that the movable blade 5 can rotate more smoothly, and the gap between the upper end of the outer wall of the movable blade 5 and the inner wall of the stationary blade 3 is smaller than the diameter of the nose hair, and the gap range is 0.01mm~0.1mm, which can effectively prevent nose hair debris from falling into the deep of the blade head and prevent hair from being clamped. Moreover, the movable blade 5 and the stationary blade 3 are highly concentric, so that the transmission assembly 11 can be fine-tuned through the constraint of the force between the movable blade 5 and the stationary blade 3, reducing the eccentricity error between the motor shaft in the nose hair shaving device main unit and the central axis of the movable blade 5, which can effectively reduce the vibration of the nose hair shaving head during operation and reduce noise.

[0038] Specifically, a receiving groove 10 for expanding the volume of the storage chamber 9 is provided at one end of the plug 8 close to the blade 7. The receiving groove 10 can collect the broken hair debris to the bottom of the storage chamber 9, and the broken hair debris can be poured out from the blade 7 during cleaning.

The movable blade 5 is clamped and assembled by the plug 8 and the clamping block 20 to ensure synchronous rotation between the three. At the same time, the plug 8 is tightly plugged into the transmission shaft 14 through the socket 18 to ensure that the movable blade 5 rotates synchronously with the transmission assembly 11. A limit mounting piece 23 for preventing the movable knife 5 from falling off is provided inside the outer shell 1 and below the clamping block 20, the transmission assembly 11 is located inside the limit mounting piece 23, the top end of the top block 13 abuts against the inner wall of the top end of the limit mounting piece 23, and a second through hole 24 for passing the transmission shaft 14 is provided at the center of the top end of the limit mounting piece 23, the outer shell 1 and the bottom cover 2 are assembled and fixed by buckling, the limit mounting piece 23 is buckled and installed inside the outer shell 1 and the top end of the bottom cover 2 abuts against the limit mounting piece 23.

[0040] Specifically, the transmission assembly 11 includes a base 12, on which is provided a top block 13 which rotates synchronously with the base 12, a spring 15 is provided between the base 12 and the top block 13, the top block 13 is movably buckled and installed on the base 12, a transmission shaft 14 which extends upward to be inserted into the socket 18 is provided at the upper end of the top block 13, and the top block 13 and the base 12 can be movably fine-tuned to reduce the eccentricity error between the motor shaft in the nose hair shaver main unit, the transmission shaft 14 and the central axis of the movable knife 5, thereby reducing the vibration and reducing the noise, and a slot 16 for connecting the nose hair shaver main unit is provided at the bottom end of the base 12.

[0041] Specifically, Figure 1 to Figure 7 As shown, in the first embodiment of the nose hair shaving head, a clamping plate 27 is provided at the bottom end of the stationary blade 3, and a fixing groove 28 for clamping the clamping plate 27 is provided at the top end of the inner wall of the outer shell 1. During assembly, the stationary blade 3 only needs to be clamped into the fixing groove 28 through the clamping plate 27.

[0042] In addition, if Figure 8 to Figure 11 As shown, in the second embodiment of the nose hair shaving head, the stationary blade 3 and the outer shell 1 are integrated and are made of metal, and can be processed and produced by a stamping process, thereby enhancing production efficiency and making the appearance of the nose hair shaving head more exquisite.
