The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0033] The razor heads of rotary shavers currently on the market mostly adopt a movable design with a massage effect. However, these products have many structural parts and are complicated to install, which increases the production cost.

[0034] In view of this, the utility model provides a circular knife assembly with self-elasticity and a razor. Figure 1-5 For an embodiment of the self-elastic circular knife 4 assembly provided by the utility model, please refer to Figure 1-5 The circular knife assembly 100 with self-elasticity includes a bracket 1, a mesh cover 2, a fixing frame 3 and a circular knife 4.

[0035] Specifically, the bracket 1 has a circular opening 1a, and a first connecting portion 11 and a second connecting portion 12 are provided along the opening 1a; the circular mesh cover 2 is installed in the opening 1a and exposed from the opening 1a, and the mesh cover 2 is provided with a first matching portion 2a corresponding to the first connecting portion 11, so that the mesh cover 2 is connected to the bracket 1; the fixing frame 3 is provided with a second matching portion 3a corresponding to the second connecting portion 12, so that the fixing frame 3 is connected to the bracket 1; the circular knife 4 is rotatably arranged between the mesh cover 2 and the fixing frame 3, that is, it can rotate relative to the mesh cover 2 and the fixing frame 3; wherein, the fixing frame 3 is provided with an elastic member 31 abutting against the mesh cover 2, and when the mesh cover 2 is floating, the mesh cover 2 is elastically reset by virtue of the elastic potential energy of the elastic member 31.

[0036] In the technical solution of the utility model, an elastic member 31 is designed on the fixing member, and the elastic member 31 is in contact with the mesh cover 2, so that when the user is shaving, the user puts the face against the shaving surface of the mesh cover 2, and drives the mesh cover 2 to move forward and backward on the shaving surface, so that the elastic member 31 undergoes elastic deformation; when the face is away from the shaving surface of the mesh cover 2, the mesh cover 2 is reset by virtue of the elasticity of the elastic member 31, thereby achieving a floating effect. The circular knife assembly 100 in this solution has a simple structure and is easy to install, which can greatly reduce the manufacturing cost of the product.

[0037] To install the grille 2 in the opening 1a of the bracket 1, refer to Figure 1 In one embodiment of the utility model, the first connection part 11 is a block provided on the wall of the opening 1a, the opening end of the mesh cover 2 is provided with a convex edge extending outward along its circumferential direction, and the first matching part 2a is an open groove provided on the outer peripheral edge of the mesh cover 2, that is, an open groove formed on the convex edge. It should be noted that the block and the open groove are matched and connected, and only the circumferential and radial movements of the mesh cover 2 are restricted, but the axial movement of the mesh cover 2 is not restricted.

[0038] In order to enable the mesh cover 2 to move axially relative to the bracket 1, please refer to the figure. In one embodiment of the utility model, two first connecting parts 11 and two first matching parts 2a are provided, and they are symmetrically arranged. This design allows the connection between the mesh cover 2 and the bracket 1 to form a support point, and the mesh cover 2 can float relative to the support point. Especially when the shaving surface of the mesh cover 2 contacts the human skin, due to the squeezing of the force point, part of the shaving surface and the skin are in closer contact.

[0039] To mount the fixing bracket 3 on the bracket 1, refer to Figure 1 , Figure 4 and Figure 5 In one embodiment of the utility model, the second connection portion 12 is a buckle provided on the wall of the opening, and the second matching portion 3a is a bayonet provided on the outer periphery of the fixing frame 3. The buckle has a certain elasticity, and when the fixing frame 3 is installed, the bayonet presses the buckle outward, thereby limiting the fixing frame 3 radially on the bracket 1. Similarly, two second connection portions 12 and two second matching portions 3a are provided.

[0040] See also Figure 1 and Figure 2 It should be understood that in order to further limit the axial movement of the mesh cover 2, the first connecting portion 11 and the second connecting portion 12 are two parts on the same component. When the buckle serving as the second connecting portion 12 is connected to the fixing frame 3, there is a gap between the mesh cover 2 and the fixing frame 3, so that the axial movement of the mesh cover 2 on the block serving as the first connecting portion 11 is restricted.

[0041] Further, to prevent the fixing frame 3 from axially moving relative to the bracket 1, please refer to Figure 1 In one embodiment of the utility model, the bracket 1 is provided with a plurality of protrusions 13 along the opening 1a, and each protrusion 13 abuts against the end surface of the fixing frame 3 to limit the fixing frame 3 and prevent it from moving in the axial direction. Correspondingly, the fixing frame 3 is also provided with a protrusion abutting against the bracket 1 (not shown in the figure).

[0042] To make the mesh cover 2 and the fixing frame 3 elastically connected, please refer to Figure 1 and Figure 3 In one embodiment of the utility model, the elastic member 31 is a convex rib extending in the circumferential direction, and a contact point 311 abutting against the mesh cover 2 is provided on the convex rib. When the mesh cover 2 moves axially under force, the contact point is squeezed and the convex rib undergoes elastic deformation; when the force on the mesh cover 2 disappears, the elastic potential energy of the convex rib resets the mesh cover 2.

[0043] For further information, see Figure 3 In this embodiment, two convex ribs are provided and are spaced apart relative to the first matching portion 2a (ie, the supporting point of the mesh cover 2), and at least one contact point 311 is provided on each convex rib so that the mesh cover 2 can be smoothly reset.

[0044] To facilitate installation of the circular knife assembly 100, refer to Figure 1In one embodiment of the utility model, a round sink 3b is provided on the end surface of the fixing frame 3 facing away from the mesh cover 2, and an iron sheet 5 is provided inside the round sink 3b. Since the fixing frame 3 is usually made of plastic, it is not possible to avoid plastic deformation and thus causing the connection failure between the fixing frame 3 and the bracket 1. The iron sheet 5 can enhance the strength of the fixing member 3, prevent it from deforming, and strengthen the connection strength between the fixing frame 3 and the bracket 1. Further, in order to facilitate the installation of the iron sheet 5, please refer to the circular knife assembly 100. Figure 3 , Figure 4 and Figure 5 In one embodiment of the utility model, the outer periphery of the circular sink 3b is provided with a plurality of clamping parts, each clamping part includes a plurality of first clamping parts 32 and a plurality of second clamping parts 33 (preferably a semicircular notch 5a), and the iron sheet 5 is provided with a plurality of notches 5a, wherein some of the notches 5a correspond one-to-one with each first clamping part 32, so that the iron sheet 5 enters the circular sink 3b; after the iron sheet 5 is rotated to a certain angle, another part of the notches 5a (preferably a semicircular notch 5a) corresponds one-to-one with each second clamping part 33, and restricts the iron sheet 5 from continuing to rotate, and each first clamping part 32 restricts the axial movement of the iron sheet 5, and when the iron sheet 5 needs to be disassembled, the iron sheet 5 is rotated out in the opposite direction when it was rotated in. Since there will be residual beards inside the circular knife assembly 100, you can use a little force to open the bayonet of the fixing member 3 and the buckle of the bracket 1, so as to further remove the circular knife 4 for cleaning.

[0045] The utility model also provides a razor, which comprises the above-mentioned circular blade assembly 100 with self-elasticity.

[0046] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
