Description

Technical Field

[0001] The utility model specifically relates to a nose hair trimmer with a replaceable blade head. Background Art

[0002] With the progress of the times, people are paying more and more attention to their own image. Nose hair trimmers have become a personal care appliance favored by men and women. Nose hair trimmers are used to trim overlong nose hairs. People can use them to trim their nose hairs and keep the nasal cavity clean. One of the commonly used structural designs is to insert a blade into the nostril and complete the trimming process through the rotation of the blade. Its general principle is similar to that of an electric shaver.

[0003] For users, there are different choices for the cutter head to achieve different trimming effects. At present, the overall cutter head replacement mode is generally adopted for the replacement of the cutter head. For example, the multifunctional trimmer disclosed in Chinese patent CN217072459U sets the connection mode between the entire cutter head and the body as a snap-fit ​​fixation mode, thereby realizing the replaceable design of the entire cutter head. This replacement mode has high requirements for the connection structure of the cutter head, but long-term use will also cause wear to it, thereby resulting in a loose connection structure. At the same time, the snap-fit ​​connection mode requires the replacement of the entire cutter head, and its replacement cost is relatively high. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0024] As shown in the figure, the utility model provides a nose hair trimmer with a replaceable blade, which comprises: a nose hair trimmer body and a blade assembly detachably matched therewith, wherein the blade assembly comprises a blade head and a blade net.

[0025] The nose hair clipper body 2 has an opening at one end for the blade to pass through and to be linked with a driving mechanism placed in the nose hair clipper body. A magnetic part is provided at the opening. The nose hair clipper body has built-in related components for driving the blade to rotate, such as a driving mechanism 4, a control mechanism, a battery, etc., that is, it is a complete nose hair clipper without the blade assembly.

[0026] The bottom of the cutter head 3 can enter the interior of the nose hair trimmer body through the opening, and cooperate with the driving mechanism, and can be driven by the driving mechanism to rotate relatively, and the bottom is limited by the driving mechanism, and the upper end is limited by the knife net, thereby supporting and fixing the cutter head, so that it can rotate circumferentially under the drive of the driving mechanism to achieve cutting action.

[0027] The knife net 1 covers the knife head and forms a cutting cooperation with the rotating knife head. The bottom of the knife net forms a magnetic attraction cooperation with the magnetic part. The top of the knife net is provided with a cutting opening for the nose hair and other hair to enter.

[0028] The magnetic part 5 is a ring-shaped magnet, which is fixed at the opening. The use of a ring-shaped magnet can avoid interference with the cutter head. At the same time, a design of multiple magnets can also be adopted, which are circumferentially distributed at the opening to achieve magnetic fixation of the knife net. At the same time, the magnetic force is large enough to firmly adsorb the knife net, and it is best to use a large force to achieve disassembly of the knife net to avoid separation during use.

[0029] A mounting step 21 is provided at the opening, and the magnetic part is fixed on the mounting step. The annular magnet can be directly embedded in the mounting step by interference fit and limited by its inner wall. For multiple magnets, the magnets can be placed by setting a number of slots arranged in a circumferential array to fix the magnets and then adsorb the knife net. At the same time, no matter whether an annular magnet or multiple magnets are used, the surface of the knife net in contact with it is a plane, thereby ensuring the reliability of the connection between the two.

[0030] The cutter head 3 includes a cutter head seat 31 and a movable knife 32 arranged on the cutter head seat. The cutter head seat includes a connecting section 311 extending toward the top along the extension direction of the cutter head seat. The connecting section is partially placed in the knife net. The movable knife is arranged on the connecting section. The blade of the movable knife is attached to the inner wall of the knife net. The movable knife on the connecting section is placed on the inner wall of the knife net, and cutting is achieved by circumferential rotation.

[0031] There are at least two movable knives symmetrically arranged on both sides of the connecting section, and a support block 313 is located on the connecting section and extends outward between adjacent movable knives to fit the inner wall of the knife net. The design of the support block ensures that the movable knife seat is always in the axial direction to avoid its shaking and affect the cutting effect.

[0032] The bottom of the blade seat extends downward to form a linkage seat 312 that is linked to the driving mechanism. The connection between the linkage seat and the connecting section extends outward in the circumferential direction to form a baffle 314 that cooperates with the inner wall of the opening or the inner wall of the magnetic part. The baffle is designed to isolate the upper end space from the internal space of the nose hair trimmer body at the lower end to prevent the cut hair from entering the internal space. At the same time, it can also maintain the same axis at all times, or the upper end surface of the baffle is used to cooperate with the mounting portion of the blade net to achieve a sealing effect between the two.

[0033] The bottom of the knife net is bent outward to form a mounting portion that can cooperate with the magnetic part, and the knife net is directly magnetically set to the opening through the mounting portion and completely covers the knife head. The bent mounting portion can better utilize the material of the knife net itself to form a magnetic fit with the magnetic part, and the cost is lower.

[0034] The embodiments should not be regarded as limiting the present invention, but any improvements based on the spirit of the present invention should be within the protection scope of the present invention.
