detailed description

In order to explain the technical content and structural features of the present application in detail, the following description will be further described in conjunction with the accompanying drawings.

Referring to FIGS. 1 through 3, the swingable interconnecting member 10 of the present application includes a lower end assembly 10a for engaging with the handle 20 in the razor 100 and for use with the cutter head 30 in the razor 100. The upper end assembly 10b is assembled such that the cutter head 30 is assembled with the handle 20 by the swingable interconnecting member 10.

As shown in FIG. 1 and FIG. 2, the swingable interconnecting member 10 of the present application further includes a shaftless swinging structure 10c between the upper end assembly portion 10b and the lower end assembly portion 10a, and the shaftless swinging structure 10c includes a swingable type. The interconnecting member 10 is arranged at least two layers of the partitioning groove 11 in the up and down direction (ie, the direction indicated by the arrow A and the opposite direction) and the deformation ring 12 located between the adjacent two layers of the partitioning groove 11. The dividing groove 11 is slidable The circumferential direction of the piece is opened, and the deformation ring 12, the upper end assembly portion 10b and the lower end assembly portion 10c are integrally connected; therefore, during the shaving process, the upper end assembly portion 10b passes through the deformation ring 12 relative to the lower end assembly portion 10a. Swinging, the purpose of swinging the cutter head 30 relative to the handle 20 during the shaving process is achieved, and the swinging direction of the cutter head 30 relative to the handle 20 during the shaving process is the left-right swing direction as indicated by the arrow B in FIG. 3, and FIG. The up and down direction of the arrow indicated by the middle arrow C, but not limited to this. Specifically, in the present embodiment, the deformation ring 12, the upper end assembly portion 10b, and the lower end assembly portion 10c are formed by an integral injection molding method to ensure the connection strength of the three, but not limited thereto. It can be understood that since the deformation ring 12 needs to be elastically deformed during the shaving process to meet the requirement that the cutter head 30 swings relative to the handle 20, the deformation ring 12 is made of a material capable of elastic deformation, such as an elastic material. However, the material of the deformation ring 12 is well known to those skilled in the art and will not be described in detail herein.

As shown in FIG. 1, in the present embodiment, the partitioning groove 11 includes a first dividing groove 111 and a second dividing groove 112. The first dividing groove 111 penetrates the left side wall, the front side wall and the rear side wall of the swingable interconnecting member 10. The second dividing groove 112 penetrates the right side wall, the front side wall and the rear side wall of the swingable interconnecting member 10, and the state is as shown in FIG. 1. The purpose of the design is to strengthen the deformation ring 12, the upper end assembly portion 10b, and Under the premise of the connection strength of the lower end assembly portion 10a, the elastic deformation ability of the deformation ring 12 when the cutter head 30 is swung relative to the handle 20 is also facilitated. Specifically, in the present embodiment, the first separation groove 111 and the second separation groove 112 are respectively arranged in a layer shape along the up and down direction of the swingable interconnection member 10 to form more deformation rings 12 to facilitate the cutter head 30. Swinging relative to the handle 20; more specifically, the first dividing groove 111 is offset from the second dividing groove 112 in the up and down direction of the swingable interconnecting member 10 to form more deformation rings 12 in an effective size, which is more advantageous The swinging of the cutter head 30 relative to the handle 20 is required. For example, in the present embodiment, the first dividing grooves 111 are alternately arranged with the second dividing grooves 112 in the up and down direction of the swingable interconnecting member 10 such that the first dividing grooves 111 and the second dividing grooves 112 are perpendicular to each other. Projections on the plane of the centerline of the oscillating interconnecting member 10 are in a partially overlapping arrangement, i.e., the plane is perpendicular to the centerline of the oscillating interconnecting member 10, on the one hand such that the oscillating interconnecting member 10 is obtained within a specified size range. More deformation rings 12, on the other hand, the deformation ring 12 surrounded by the adjacent two first separation grooves 111 and the deformation ring 12 surrounded by the adjacent two second separation grooves 112 by the first separation groove 111 and the The projection portions of the two separation grooves 112 are overlapped to have better elastic deformation ability, thereby facilitating the swing of the cutter head 30 relative to the handle 20, but not Limited. Preferably, as shown in FIG. 1 , in the embodiment, the upper slot wall of the first partition slot 111 is a sloped structure 114 , and the lower slot wall of the first partition slot 111 is a planar structure 113 , and the first partition slot The inclined structure 114 in the 111 is inclined upwardly with respect to the planar structure 113 in the first dividing groove 111; the lower groove wall of the second dividing groove 112 is a bevel structure 116, and the upper groove wall of the second dividing groove 112 is a planar structure. 115, the bevel structure 116 in the second separation groove 112 is inclined downwardly with respect to the planar structure 115 in the second separation groove 112, so that the deformation ring 12 provides more elastic deformation space when the cutter head 30 swings relative to the handle 20. Further, the reliability of the cutter head 30 to swing relative to the handle 20 is ensured, and the degree of fit of the cutter head 30 to the skin is maximized, thereby improving shaving comfort and effects, but not limited thereto.

Compared with the prior art, since the swingable interconnecting member 10 of the present application further includes a shaftless swinging structure 10c between the upper end joint portion 10b and the lower end joint portion 10a, the shaftless swinging structure 10c includes a swingable interconnecting member. 10, at least two layers of the partitioning groove 11 and the deformation ring 12 between the adjacent two layers of the partitioning groove 11 are arranged in the vertical direction, and the partitioning groove 11 is opened along the circumferential direction of the swingable interconnecting member 10, and the deformation ring 12 and the upper end assembly portion are opened. 10b and the lower end assembly portion 10a are integrated into one body. Therefore, during the shaving process, the upper end assembly portion 10b is swung by the deformation ring 12 relative to the lower end assembly portion 10a to satisfy the shaft 30 swinging relative to the handle 20 without the shaft. The purpose is to replace the existing cutter head 30 by adding a pivot structure with respect to the handle 20, and the assembly complexity and assembly difficulty caused by the increase of the pivot structure; at the same time, the existing pivot is also overcome. The shaft structure is fixed by the pivoting center and is in close contact with the skin, which is a defect that the shaving effect is not good.

It should be noted that since the upper end assembly portion 10b and the lower end assembly portion 10a are relatively oscillated by the deformation portion 12, the swingable interconnection member 10 of the present application is oscillated by itself during the shaving process, thereby realizing the cutter head 30 relative to the cutter head 30. The purpose of the handle 20 swinging.

The above is only the preferred embodiment of the present application, and the scope of the application is not limited thereto, and thus equivalent changes made in the claims of the present application are still within the scope of the present application.
