[0041] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0042] like Figure 1-6 As shown, the following embodiment discloses a nose hair trimmer that is easy to install.

[0043] include,

[0044] The housing 100 has an inner cavity, and the head is provided with an avoidance hole 101 capable of accommodating the extension of the cutter head assembly 200;

[0045] The cutter head assembly 200 at least comprises a relatively movable moving cutter 220 and a fixed cutter 210, wherein the fixed cutter 210 can extend out of the avoidance hole 101;

[0046] The driving assembly includes at least one driving component 500 located inside the housing 100 and connected to the cutter head assembly 200 for driving the movable cutter 220 to move;

[0047] The driving assembly and the cutter head assembly 200 are driven by a transmission assembly 400, and the transmission assembly 400 includes a transmission wheel 410 and a transmission sleeve 420 in sequence along the transmission direction. The first end of the transmission wheel 410 is connected to the rotating end 510 of the driving component 500, and the second end is limitedly connected to the transmission sleeve 420 to drive the transmission sleeve 420;

[0048] A supporting member 300 is provided between the transmission sleeve 420 and the cutter head assembly 200 . The supporting member 300 supports the transmission sleeve 420 toward one side of the transmission wheel 410 , so that the transmission sleeve 420 is automatically inserted into the transmission wheel 410 .

[0049] The above is the basic solution of this embodiment.

[0050] Reference Figure 1 and Figure 2As shown, the cutter head assembly 200 is arranged at the head of the shell 100, the fixed knife 210 is a cover body, and a trimming groove 211 is provided on the end face. At the same time, the end of the fixed knife 210 extends to the outside of the shell 100 through the avoidance hole 101; the head of the movable knife 220 is located inside the cover body of the fixed knife 210. When in use, the movable knife 220 rotates under the action of the driving assembly, and a trimming part is formed between the movable knife 220 and the trimming groove 211 of the movable knife 220. The user extends the head of the cutter head assembly 200 into the nostril, and the nose hair is inserted into the fixed knife 210 from the trimming groove 211. When the movable knife 220 rotates, an angle is formed between the blade and the groove wall of the trimming groove 211, which is the trimming part. When the angle is reduced, the nose hair is trimmed.

[0051] During assembly, the transmission wheel 410 is fixed to the rotating end 510 of the driving component 500, the driving component 500 and the transmission wheel 410 are installed in the housing 100, and the transmission sleeve 420 is inserted, with the open side of the transmission sleeve 420 facing the transmission wheel 410, and the top holding member 300 is installed on the cutter head assembly 200. When the cutter head assembly 200 is installed, due to the action of the top holding member 300, the transmission sleeve 420 has pressure toward the side of the transmission wheel 410, and the transmission sleeve 420 is pressed toward the side of the transmission wheel 410, so that the transmission sleeve 420 is automatically inserted into the transmission wheel 410 and connected to the transmission wheel 410.

[0052] When assembling the trimmer, the positions of the driving component 500 and the cutter head are limited on the shell 100, that is, the distance between the driving component 500 and the cutter head is certain. Therefore, when the cutter head is installed to the head of the shell 100, due to the action of the top holding member 300, in a natural state, the distance between the cutter head assembly 200 and the transmission driving component 500 is greater than the set limit distance. Therefore, when the assembler presses the cutter head assembly 200 toward one side of the driving component 500, the unfixed component, namely the transmission sleeve 420, will be pressed toward one side of the driving component 500 under the action of the top holding member 300, thereby achieving connection and fixation with the transmission sleeve 420.

[0053] Preferably, the driving component 500 in this embodiment is generally a driving motor.

[0054] In order to prevent the supporting member 300 from shifting or falling off the cutter head assembly 200 during the installation process, in this embodiment, an accommodation portion is provided between the transmission sleeve 420 and the cutter head assembly 200 to limit the position of the supporting member 300;

[0055] The accommodating structure at least includes an accommodating groove a and a limiting shaft 421 that cooperates with the accommodating groove a. The supporting member 300 is located in the accommodating groove a and supports the end surface of the limiting shaft 421 .

[0056] The accommodating groove a and the limiting shaft 421 are respectively arranged on the cutter head assembly 200 and the transmission sleeve 420. In this embodiment, for the convenience of understanding, one of the arrangement modes is selected for description.

[0057] Reference Figure 3 As shown, in this embodiment, the accommodating groove a is arranged on the cutter head assembly 200, preferably on the movable knife 220, and an extended portion with an end opening is formed at the lower end of the movable knife 220 to form the accommodating groove a; at the same time, the limiting shaft 421 is arranged on the transmission sleeve 420, the lower end of the transmission sleeve 420 is a sleeve portion, and a rod portion extends from the upper end as the limiting shaft 421.

[0058] During assembly, the supporting member 300 is placed into the receiving groove a, and then the receiving groove a is inverted and inserted into the limiting shaft 421, so that the lower end of the supporting member 300 abuts against the end of the limiting shaft 421;

[0059] When the cutter head assembly 200 is pressed down, the two ends of the supporting member 300 are respectively in contact with the bottom of the accommodating groove a and the end surface of the limiting shaft 421 .

[0060] Preferably, in this embodiment, the limiting shaft 421 needs to drive the cutter head assembly 200 to rotate when the transmission sleeve 420 rotates. Therefore, a limiting structure is set between the limiting shaft 421 and the accommodating groove a to fix it in the rotation direction. The specific implementation method is to set the accommodating groove a as a polygonal groove, and the limiting shaft 421 is also set as a polygonal column consistent with the polygonal groove.

[0061] Preferably, in this embodiment, the supporting member 300 is a spring, and a limiting column 221 is provided at the bottom of the accommodating groove a.

[0062] The purpose of setting the limit column 221 is that the spring can be mounted on the limit column 221, thereby avoiding the problem of poor holding force of the spring due to tilting during assembly. At the same time, the spring is easily deformed when used in a tilted state, shortening its service life.

[0063] The specific implementation of the transmission assembly 400 in this embodiment is as follows: the first end of the transmission sleeve 420 is set to be open, and can accommodate the transmission wheel 410 extending into the interior; a transmission structure is provided between the interior of the transmission sleeve 420 and the transmission wheel 410.

[0064] When the transmission sleeve 420 moves toward the transmission wheel 410 under the action of the supporting member 300, the upper portion of the transmission wheel 410 is inserted into the transmission sleeve 420, and a transmission structure is formed between the transmission sleeve 420 and the transmission wheel 410;

[0065] When the transmission sleeve 420 and the transmission wheel 410 are separated or not assembled in place, the transmission structure cannot be formed, so even if the driving mechanism is started, the transmission assembly 400 cannot be driven, and the trimmer cannot be turned on;

[0066] Based on the above description, the transmission structure can also be used as a protective structure, and the transmission sleeve 420 must be assembled in place before the trimmer can be used.

[0067] In this embodiment, the specific implementation of the transmission structure is as follows: the transmission structure includes a driving portion 411 disposed on the transmission wheel 410 , and the transmission sleeve 420 is provided with a push wall 422 that can be driven by the driving portion 411 .

[0068] The driving part 411 is convexly arranged on the transmission wheel 410. When the transmission wheel 410 extends into the transmission sleeve 420, the driving part 411 contacts the push wall 422 inside the transmission sleeve 420. When the transmission wheel 410 rotates under the action of the driving motor, the driving part 411 also rotates, pushing the push wall 422 together, so that the transmission sleeve 420 rotates accordingly.

[0069] In this embodiment, the transmission wheel 410 rotates around the axis. In order to realize the driving part 411 driving the push wall 422, the driving part 411 can be set at any position except the axis, so that it also rotates around the axis when rotating.

[0070] Preferably, refer to Figure 4 and Figure 5 As shown, in this embodiment, the driving part 411 is an eccentric shaft arranged on the end surface of the transmission wheel 410; the pushing wall 422 is protruding on the inner wall of the transmission sleeve 420.

[0071] When the transmission wheel 410 rotates, the eccentric shaft rotates around the axis of the transmission wheel 410, thereby pushing the push wall 422 to rotate around the axis of the transmission wheel 410. The transmission sleeve 420 and the transmission wheel 410 are coaxially arranged, so the transmission sleeve 420 can rotate.

[0072] When the transmission structure is in the transmission process, the transmission wheel 410 rotates around its axis, and the transmission sleeve 420 also rotates around the same axis under the action of the driving component 500. However, since the connection between the transmission wheel 410 and the transmission sleeve 420 is not stable, once the transmission wheel 410 escapes from the transmission sleeve 420, the transmission cannot continue. The specific implementation method for solving this problem in this embodiment is as follows: a plurality of claws 423 are provided on the opening edge of the transmission sleeve 420 extending toward one side of the transmission wheel 410; the holding space surrounded by the plurality of claws 423 is consistent with the shape of the transmission wheel 410.

[0073] Reference Figure 4 and Figure 5As shown, the claw 423 is a protrusion arranged on the opening edge of the transmission sleeve 420, and its inner end face is a holding end face. Multiple claws 423 are arranged along the edge of the transmission sleeve 420, and the holding space surrounded by multiple end faces is consistent with the shape of the transmission wheel 410.

[0074] Preferably, in this embodiment, the outer shape of the transmission wheel 410 is set to be cylindrical, so the cross-section of the holding space is a circle.

[0075] At the same time, in order to ensure the clamping effect, in this embodiment, the inner diameter of the cross section of the clamping space is not greater than the diameter of the transmission wheel 410.

[0076] When the cutter head assembly 200 is not installed, the transmission sleeve 420 is placed in the shell 100. Due to the action of the claws 423, usually only a very small part of the head of the transmission wheel 410 extends into the transmission sleeve 420, or the end face of the transmission wheel 410 contacts the claws 423. When the cutter head assembly 200 is installed, due to the action of the supporting member 300, the transmission sleeve 420 is pressed toward one side of the transmission wheel 410, so that the claws 423 move downward along the outer end face of the transmission wheel 410 to clamp the transmission wheel 410. At the same time, the transmission wheel 410 further extends into the transmission sleeve 420, and the transmission structure is assembled in place.

[0077] In order to ensure that the claw 423 can smoothly hold the transmission wheel 410, in this embodiment, an inclined guide surface 423.1 is arranged between the inner end surface of the claw 423 and the end surface facing the driving component 500.

[0078] Reference Figure 4-Figure 6 As shown, preferably, the outermost end of the guide surface 423.1 is located outside the transmission wheel 410. Therefore, when the cutter head assembly 200 is not installed, the outer edge on the end surface of the transmission wheel 410 is in line contact with the guide surface 423.1; during the downward pressing process, the outer edge of the end of the transmission wheel 410 slides along the guide surface 423.1, so that the entire transmission wheel 410 slides into the holding space of the claw 423, thereby ensuring that it can enter the guide sleeve along the claw 423.

[0079] If the guide surface 423.1 is not provided, when the cutter head assembly 200 is not installed, the end face of the transmission wheel 410 contacts the end of the claw 423. During the pressing process, extrusion occurs between the end face of the transmission wheel 410 and the claw 423, making it impossible for the claw 423 to enter the transmission sleeve 420, and it is more likely that the claw 423 will be squeezed and broken.

[0080] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
