Example one

A shaver is a common daily product.

A shaver is generally composed of two parts, a shaver head and a handle. Wherein, the razor tool bit belongs to the core part of razor, and it has very big influence to shaving effect and user's use experience.

Referring to fig. 1, in the present embodiment, a razor head for a hand razor is provided, which includes a base 1 having a blade 10. The blade 10 is not shown in fig. 1.

The base 1 includes a mounting portion 2 for mounting a blade 10 and a connecting portion 3 for connecting a handle.

A flexible piece is arranged between the mounting part 2 and the connecting part 3, wherein the mounting part 2 and the connecting part 3 are rotatably connected through the flexible piece.

Before shaving beards, the handle is mounted to the connecting portion 3. Wherein, the handle can be fixed on the connecting part 3 by screw connection or clamping connection and the like.

During shaving, the handle is held by hand while the blades 10 of the mounting portion 2 are engaged with the skin.

During shaving, the hand is forced on the handle to ensure that the blade 10 is engaged with the skin, on the one hand, and to move the razor, on the other hand. The blade 10 is in contact with the skin and the blade 10 cuts a hair as the shaver moves, thereby achieving the purpose of shaving.

Because installation department 2 and connecting portion 3 can take place relative rotation under the effect of flexible piece, so, when shaving chin or the great position of facial radian, the user can be along with the change of facial profile, the size of adjusting the handle power, changes the contained angle of installation department 2 and connecting portion 3 from this for under the prerequisite of small amplitude rotation handle, blade 10 just can keep laminating with facial skin, thereby the operation of conveniently shaving.

When shaving, the user does not need to frequently and greatly rotate the wrist or the arm to drive the shaver, thereby reducing the fatigue of the hand of the user.

The force for shaving can vary for different parts of the face.

When the force suddenly becomes small, the blade 10 may be detached from the skin due to the action of the hand; when the blade 10 is then applied to the skin again, scratching of the skin may occur due to uneven application of force.

In this embodiment, the flexible member has elasticity, and when the handle is applied with force, a part of energy can be absorbed and converted into elastic potential energy.

The flexible member may be deformed to some extent by applying force to the handle during shaving. The deformed flexible member has elastic potential energy, and at this time, even if the force applied by the hand changes to a certain extent, the blade 10 can keep a state of being attached to the skin under the action of the flexible member, so that the risk of scratching can be reduced, and the shaving effect can be improved.

In this embodiment, the base 1 may be a one-piece structure, in which the mounting portion 2, the connecting portion 3 and the flexible member are integrally formed.

The base 1 may be made of silicone. The mounting part 2, the connecting part 3 and the flexible part can be integrally formed by injection molding and other processes.

Further, the base 1 may be made of other non-toxic, harmless and materials.

The mounting portion 2 and the connecting portion 3 are larger with respect to the thickness of the flexure in consideration of the mechanical properties of the base 1. Wherein the mounting portion 2 and the connecting portion 3 have a lower stiffness than the flexible member, and the mounting portion 2 and the connecting portion 3 are less likely to deform during shaving.

As shown in fig. 2, the flexible member comprises a first connecting arm 4 and a second connecting arm 5, wherein both the first connecting arm 4 and the second connecting arm 5 are symmetrically arranged.

In the present embodiment, the mounting portion 2 and the connecting portion 3 are both symmetrical structures, and the symmetrical planes of the two coincide with each other.

The first and second connecting arms 4 and 5 may be symmetrically disposed about a symmetrical plane of the mounting portion 2 or the connecting portion 3 in consideration of structural symmetry and aesthetic appearance.

Referring to fig. 2 and 3, the front portions of the first and second connecting arms 4 and 5 are connected to both ends of the bottom side of the mounting portion 2, respectively, and the rear portions of the first and second connecting arms 4 and 5 are connected to the left and right sides of the connecting portion 3, respectively.

Due to the flexible member, relative rotation between the mounting portion 2 and the connecting portion 3 can occur when external force is applied. However, unlike the rigid member or the rigid connection, the flexible member cannot effectively transmit all the force applied to the handle by the hand to the blade 10, and when the resistance applied to the blade 10 is large, the cutting force of the blade 10 may be insufficient, which may affect the smoothness and effect of shaving.

For this reason, in the present embodiment, the base 1 is provided with a rotation limiting structure for limiting a rotation angle between the mounting portion 2 and the connecting portion 3.

In the shaving process, when the mounting portion 2 and the connecting portion 3 cannot rotate relatively, the force applied by the hand to the handle can be better transmitted to the blade 10 of the mounting portion 2, so that the cutting force of the blade 10 is ensured, and the shaving work can be smoothly carried out.

As shown in fig. 4, the rotation restricting structure includes a boss 6 provided on the mounting portion 2 and a cantilever 7 provided on the connecting portion 3. When the mounting portion 2 rotates a certain angle relative to the connecting portion 3, the cantilever 7 contacts and abuts against the protrusion 6, so that the mounting portion 2 cannot rotate continuously. Wherein hatching is not shown in fig. 4.

Referring to fig. 4, the connecting portion 3 is kept still, and after the mounting portion 2 is rotated counterclockwise to a certain angle, the fulcrum on the left side of the protrusion 6 is contacted with the cantilever 7. Under the action of the cantilever 7, the boss 6 cannot rotate, and therefore the connecting part 3 cannot rotate anticlockwise, and at the moment, the force of the hand on the handle is transmitted to the mounting part 2 through the cantilever 7 and the boss 6, so that the blade 10 has enough cutting force.

As shown in fig. 2 and 3, in the present embodiment, in order to mount the blades 10, the mounting portion 2 may be provided with accommodating compartments 8, wherein the accommodating compartments 8 are provided with mounting grooves 9 for mounting the blades 10, and the number of the mounting grooves 9 corresponds to the number of the blades 10.

In the accommodating bin 8, two mounting grooves 9 symmetrically arranged left and right can be regarded as a group for mounting the same blade 10, and correspondingly, the two sides of the blade 10 are provided with inserting parts 11 for inserting into the mounting grooves 9.

As shown in fig. 5, in the present embodiment, the number of the blades 10 may be set to five.

For installing the blade 10, five installation grooves 9 are respectively arranged on the left side and the right side in the accommodating bin 8. Wherein, the mounting grooves 9 on the same side can be arranged at equal intervals.

In order to place the blade 10 into the accommodating chamber 8, the accommodating chamber 8 includes an opening for placing the blade 10 and a hollow hole opposite to the opening, wherein the mounting portion 2 is detachably provided with a fixing cover 12 for sealing the opening and fixing the blade 10.

In this embodiment, the fixing cover 12 can be connected to the mounting portion 2 by clipping.

For example, each edge of the fixed cover 12 is provided with a plurality of buckles, correspondingly, the mounting part 2 is provided with clamping grooves corresponding to the buckles one by one, and the fixed cover 12 and the mounting part 2 can be fixed through the matching of the buckles and the clamping grooves.

In other embodiments, the fixing cover 12 may be fixed to the mounting portion 2 by screws.

Referring to fig. 4, before the blade 10 is mounted, the fixing cover 12 located at the upper side of the mounting portion 2 is detached, thereby opening the opening; thereafter, the blades 10 are inserted into the corresponding mounting grooves 9 from the openings; finally, the fixing cover 12 is covered to complete the fixing work of the blade 10.

After the blade 10 is mounted and fixed, the cutting edge of the lower side of the blade 10 is located outside the lower side of the mounting portion 2 through the hollow hole, so that the blade 10 can shave.

As shown in fig. 6, three pressing bars 13 may be provided on the fixing cover 12. After the fixing cover 12 is covered, the three pressing strips 13 respectively press the left side, the middle part and the right side of the blade 10, thereby limiting the moving space of the blade 10 and realizing the fixation of the blade 10.

In order to facilitate the discharge of shaving cream and cut hairs during shaving, the stationary cover 12 may be provided with a plurality of through-holes 14.

Meanwhile, due to the existence of the through hole 14, the blade 10 is convenient to clean and dry, and the blade 10 is prevented from rusting due to accumulated water in the accommodating bin 8.
