At the same time, no reset device is provided, and the cutter head cannot automatically reset after swinging. As a result, it is difficult to control the force with which the cutter head fits various positions of the face during shaving, and the cutter head is prone to cutting the skin. Summary of the invention

[0005] Purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a shaver with a floating cutter head, so that the entire cutter head can float on the body, solving the problem that it is difficult to control the force of the cutter head to be close to the face.

[0006] The technical solution of the utility model is: a razor with a floating cutter head, comprising a body part and a cutter head part, wherein the cutter head part comprises a cutter head seat and a cutter head assembly arranged on the cutter head seat, a support member is arranged in the body part, an elastic part for supporting the cutter head seat is bent upwardly on the support member, and springs are arranged between the left and right sides of the cutter head seat and the support member respectively.

[0007] By adopting the above scheme, the cutter head portion and the body portion are connected by a support member, and the elastic portion is used to support the cutter head seat on the cutter head portion, so that the entire cutter head portion is supported by the elastic portion and can move with the deformation of the elastic portion. A spring is provided to assist the deformation of the elastic portion and provide subsequent resetting power, so that the entire cutter head portion can float and reset relative to the body portion.

[0008] Further configuration of the utility model: the support member is provided with the elastic part on both the front and rear sides of the cutter head seat, the elastic part is suspended, the elastic part is provided with a mounting part for connecting the cutter head seat, and the mounting part and the cutter head seat are provided with a limiting structure for limiting the relative rotation of the cutter head seat and the mounting part.

[0009] With the above-mentioned further arrangement, the elastic part is suspended, and can realize up and down movement when the middle part is pulled or squeezed, and can automatically reset when the force is lost, and the elastic part is arranged on the front and rear sides of the cutter head seat, so that the cutter head part is supported on both the front and rear sides, and the force is more balanced, which effectively prevents the cutter head part from tipping to the front or rear side, and the relative rotation of the mounting part and the cutter head seat is limited by a limiting structure, which supports the cutter head seat while preventing the cutter head seat from rotating relative to the elastic part, so that when the cutter head seat is subjected to force on the left and right sides, it can drive the elastic part to tilt and deform, thereby realizing the tilting movement of the cutter head seat, that is, realizing the tilting movement of the cutter head as a whole in the left and right directions.

[0010] Further configuration of the utility model: the limiting structure includes a mounting hole arranged on the mounting part and mounting columns arranged on the front and rear sides of the cutter head seat, the mounting columns are clamped in the corresponding mounting holes, and the mounting columns and the mounting holes are respectively provided with a first plane and a second plane for clamping and fitting together.

[0011] With the above further arrangement, the limiting structure is a clamping structure of the mounting hole and the mounting column, and a first plane and a second plane are respectively arranged on the mounting hole and the mounting column. When clamped, the first plane and the second plane are in contact and fit with each other, so as to avoid rotation between the cutter head seat and the mounting part.

[0012] The utility model is further configured as follows: positioning columns for positioning the spring are respectively provided on the cutter head seat and the support member; one end of the spring abuts against the cutter head seat, and the other end of the spring abuts against the support member.

[0013] With the above-mentioned further arrangement, the springs arranged on the left and right sides of the elastic part play the role of supporting the cutter head seat, and can assist the cutter head seat in the up and down movement and tilting movement, as well as the subsequent resetting movement, so as to realize that the cutter head part as a whole can float relative to the body part, and by arranging positioning columns on the support member and the cutter head seat, the position of each spring can be determined and limited to prevent the spring from popping out sideways during deformation and resetting.

[0015] By adopting the above-mentioned further arrangement, the limit groove can limit the upward and downward movement distance and the left and right movement distance of the part of the elastic part extending into the limit groove, so as to prevent the elastic part from being deformed too much and becoming unable to recover or even break. Furthermore, the limit groove does not limit the rotation of the elastic part in the limit groove, and the elastic part and the cutter head seat are clamped and cannot rotate. When the cutter head seat is tilted and rotated to one side, it is ensured that the part of the elastic part extending into the limit groove can be driven to rotate in the limit groove, so as to promote the deformation of the elastic part in the left and right directions, realize the movement of the cutter head seat in the up and down directions and the tilting rotation, so as to realize the floating of the cutter head part on the body.

[0016] A further configuration of the present invention is as follows: the mounting portion, the elastic portion and the support member are integrally configured.

DETAILED DESCRIPTION

[0029] The technical scheme in this embodiment will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in 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.

[0030] It should be noted that in the description of the present invention, all directional indications (such as up, down, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0031] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that technical personnel in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0032] like Figure 1-Figure 6 As shown, the X-axis direction in the figure is the left-right direction described in the text, the Y-axis direction is the front-back direction described in the text, and the Z-axis direction is the up-down direction described in the text. A shaver with a floating cutter head includes a body 1 and a cutter head 2. The cutter head 2 includes a cutter head seat 21 and a cutter head assembly arranged on the cutter head seat 21. The cutter head assembly can be a reciprocating shaver head, including a reciprocating cutter holder arranged above the cutter head seat 21, and a matching inner blade and outer cutter net 6 are arranged above the reciprocating cutter holder. The reciprocating cutter holder and the inner blade structure are not shown in the figure. A control unit and a power supply unit are provided in the body 1. The cutter head 2 also includes a power source for controlling the movement of the cutter head 2. The power source can be a motor. The power source is electrically connected to the control unit and the power supply unit respectively. The power source drives the reciprocating cutter holder to reciprocate left and right through a power shaft, so that the inner blade cooperates with the outer cutter net 6 to cut hair.

[0033] The cutter head seat 21 is connected to the body 1 by a support member 3, which is fixed in the body 1 by screws. Two elastic parts 31 are bent on the support member 3. The elastic parts 31 can be made of elastic plastic, such as polypropylene, or can be made of elastic metal material. The two elastic parts 31 are respectively located between the front and rear end surfaces of the cutter head seat 21 and the inner wall of the adjacent body 1.

[0034] The middle parts of the two elastic parts 31 are respectively provided with mounting parts 32 for clamping with the front and rear end faces of the cutter head seat 21, so that the cutter head seat 21 is supported on both the front and rear sides. The force transmitted from the cutter head seat 21 to the support member 3 is evenly distributed on the two elastic parts 31, which effectively prevents the cutter head seat 21 and even the entire cutter head part 2 from tipping forward or backward, making the cutter head part 2 more stable. The mounting part 32, the elastic part 31 and the support member 3 can be made in one piece, so that there is no connection between them, which avoids the loosening of the connection after vibration, making the support member 3 more stable.

[0035] The elastic part 31 is suspended, and when the middle part is pulled or squeezed, the elastic part 31 can be deformed up and down, and can automatically reset when the force is lost. The mounting part 32 arranged here is snap-connected with the cutter head seat 21, so that the cutter head seat 21 can drive the entire cutter head 2 to bounce up and down with the elastic part 31.

[0036] Furthermore, the elastic portion 31 as a whole is a wavy structure extending in the left and right directions, and a mounting portion 32 is provided on the middle trough of the elastic portion 31. A limiting structure for limiting the relative rotation of the cutter head seat 21 and the mounting portion 32 is provided on the mounting portion 32 and the cutter head seat 21. The limiting structure includes a mounting hole 33 provided on the mounting portion 32 and a mounting column 22 provided on the front and rear sides of the cutter head seat 21. The mounting column 22 is snapped into the corresponding mounting hole 33, and a first plane 221 and a second plane 331 are respectively provided on the mounting column 22 and the mounting hole 33. When snapped, the first plane 221 and the second plane 331 are in contact and fit with each other, so as to avoid relative rotation of the cutter head seat 21 and the mounting portion 32. As a result, when the left and right sides of the cutter head seat 21 are subjected to force alone, after the force is transmitted to the elastic portion 31, the elastic portion 31 produces a certain degree of deformation in the left and right lateral directions and the up and down directions, so that the cutter head seat 21 can tilt along with the elastic portion 31.

[0037] The elastic part 31 has a wave crest on both sides of the mounting part 32 . The wave-shaped design makes it easier for the elastic part 31 to deform in the left and right directions in the middle, making the deformation of the elastic part 31 in the left and right directions easier and more labor-saving.

[0038] The support member 3 is arranged on one side of the direction deep into the interior of the fuselage portion 1 below the cutter head seat 21. Four positioning holes 34 are arranged on the circumference of the support member 3. A corresponding number of pins 12 for inserting into the positioning holes 34 are arranged on the inner wall of the fuselage portion 1. The positioning holes 34 can assist in positioning the support member 3 on the fuselage portion 1, facilitate the installation of the support member 3 in the fuselage portion 1, and provide a certain supporting effect to reduce the possibility of shaking of the support member 3.

[0039] The inner walls of the front and rear sides of the fuselage 1 are provided with limit grooves 11, and each mounting portion 32 extends outwardly into the limit groove 11, limiting the range of the upper and lower deformation of the elastic portion 31, and preventing the elastic portion 31 from being too deformed and unable to recover or even break. The limit groove 11 is a straight groove structure, and the outer circle part fits with the outer circle surface of the mounting portion 32 extending into the limit groove 11, so that the mounting portion 32 extending into the limit groove 11 can rotate in the limit groove 11, and the connection between the mounting portion 32 and the elastic portion 31 is realized. The elastic portion 31 is rotated and squeezed around the center of the mounting portion 32, so that the elastic portion 31 is squeezed laterally to deform when the mounting portion 32 is tilted and rotated, and elastic force is provided to restore the tilted state, while limiting the lateral displacement of the mounting portion 32 in the left and right directions, thereby preventing the cutter head seat 21 from shaking left and right, and preventing the left and right lateral displacement from affecting the tilting and rotation of the cutter head seat 21, so that the cutter head seat 21 does not shake left and right each time it is tilted, thereby enhancing the stability of the cutter head seat 21, thereby enhancing the stability of the entire cutter head 2 when floating.

[0040] Positioning columns 5 for positioning springs 4 are respectively provided on the cutter head seat 21 and the support member 3. Each spring 4 is wound around the positioning column 5. One end of the spring 4 abuts against the cutter head seat 21 and the other end abuts against the support member 3. The positioning column 5 can determine and limit the horizontal position of each spring 4 on the cutter head seat 21, thereby preventing the spring 4 from popping out laterally during the pressure-resetting process and providing further support for the cutter head 2.

[0041] The two springs 4 are respectively located on the left and right sides of the bottom surface of the cutter head seat 21. When the cutter head seat 21 is tilted or moves up and down, the two springs 4 are respectively compressed or stretched, and together with the elastic part 31, provide buffering elastic force and restoring elastic force during tilting, and together with the elastic part 31, realize the tilting rotation, up and down movement and restoring action of the cutter head seat 21, thereby realizing the floating of the entire cutter head part 2 relative to the body part 1.

[0042] Specifically, the cutter head seat 21 drives the cutter head portion 2 as a whole to move in the up and down directions and to tilt and rotate left and right, and the cutter head seat 21 is limited to move in the left and right directions by the mounting portion 32 and the limit groove 11, which can avoid shaking of the cutter head seat 21 when tilted and rotated, and the reciprocating tool holder in the cutter head portion 2 reciprocates left and right relative to the cutter head seat 21, so that the inner blade in the cutter head portion 2 can float relative to the body portion 1, thereby achieving a better fit to the user's face.
