Description

Technical Field

[0001] This utility model relates to a reciprocating razor head, and more particularly to a height adjustment mechanism for a reciprocating razor head. Background Technology

[0002] Personal care products, such as shaving devices, including the shaving head, currently have a relatively fixed height for the entire shaving head or multi-blade unit within the housing in reciprocating shavers. At most, elastic elements are used to allow the shaving head to float, but this does not change the actual height of the shaving head exposed. Furthermore, the operating switch, which operates in the same direction as the shaving head's extension, significantly impacts the aesthetic design of portable shavers, requires reversing locking, and is cumbersome to operate, resulting in poor stability. Summary of the Invention

[0003] This utility model provides a simple, easy-to-process and assemble, and aesthetically pleasing reciprocating razor head height adjustment structure.

[0004] To solve the above technical problems, this utility model adopts the following technical solution: a blade height adjustment structure for a reciprocating razor, wherein the blade assembly is installed inside a housing, and the blade height adjustment structure includes an operating frame installed on the housing, a plurality of driving columns distributed on the back of the operating frame on both sides of the drive shaft along the reciprocating direction, and a plurality of guide grooves on the outer shell of the blade assembly that are inserted and fitted into the driving columns. The plurality of guide grooves are arranged side by side along the reciprocating direction, and the guide groove includes a slanted sliding groove section extending obliquely along the shell surface in the middle, an "L"-shaped locking section that connects to the slanted sliding groove section at its highest position to form an "L"-shaped locking position for lowering the blade assembly, and a "7"-shaped locking position that connects to the slanted sliding groove section at its lowest position to form an "L"-shaped locking position for raising the blade assembly. The operating frame is exposed on the outer surface of the housing through a through hole to form an operating part. The through hole extends parallel in the reciprocating direction. By moving the operating frame laterally along the through hole, the column pushes the cutter head assembly through the inclined slide section to adjust the height, and locks at the side end of the guide groove, i.e., the "L"-shaped locking section or the "7"-shaped locking section, thereby realizing the lateral control of the cutter head assembly height adjustment.

[0005] As an improvement, several isolation protrusions are provided on the back of the operating frame away from the drive column. The isolation protrusions abut against the shell surface of the cutter head assembly with guide groove, limiting the distance between the operating frame and the cutter head assembly shell.

[0006] As an improvement, the outer surface of the isolation protrusion is curved.

[0007] As an improvement: two drive columns are symmetrically arranged on the back of the operating frame with the drive shaft as the center, and the distance between the corresponding two guide slots is the same as the distance between the two drive columns.

[0008] The beneficial effects of this invention are as follows: The lateral control of the blade head assembly height adjustment is achieved through the cooperation of the guide groove and the operating component. Simultaneously, the operating component locks in place when pushed to its limit, requiring no further operation – a single step completes the adjustment. After locking, the blade head height remains constant during use, and its lateral position within the housing remains unchanged during height adjustment, ensuring centering and strong stability. Furthermore, the entire height adjustment structure does not affect the internal structure of the blade head, making it compatible with various blade heads. It can adjust the height of the entire blade head or adjust the height of a single blade head unit, especially the side blade unit, within a multi-unit blade head. The entire structure is simple, reasonable, easy to implement, and easy to assemble, perfectly matching the design concept of portable razors, resulting in an aesthetically pleasing overall appearance.

[0009] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description

In the description of this utility model, it should be understood that the terms "connected," "joined," and "fixed," etc., used in this utility model should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can refer to a mechanical connection or a welded connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two components or the interaction relationship of two components, unless otherwise explicitly defined. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0014] like Figure 1 , Figure 2 , Figure 3As shown, in one embodiment of the reciprocating razor head height adjustment structure of this utility model, the head assembly 2 is installed inside the housing 5. The head height adjustment structure includes an operating frame 1 installed on the housing, a plurality of drive columns 11 distributed on the back of the operating frame on both sides of the drive shaft along the reciprocating direction, and a plurality of guide grooves 3 opened on the outer shell of the head assembly to be inserted and cooperate with the drive columns. In this embodiment, two drive columns 11 are symmetrically arranged on the back of the operating frame with the drive shaft as the center. The distance between the two corresponding guide grooves 3 arranged side by side along the reciprocating direction is the same as the distance between the two drive columns. The guide groove 3 includes an inclined sliding groove section 31 extending obliquely along the shell surface in the middle, an "L"-shaped locking section 32 connected to the inclined sliding groove section 31 at its highest position to form a lowering threshold locking position for the cutter head assembly, and a "7"-shaped locking section 33 connected to the inclined sliding groove section 31 at its lowest position to form a higher threshold locking position for the cutter head assembly. The operating frame is partially exposed on the outer surface of the shell 5 through the through hole 51 to form the operating part 12. For ease of assembly, in this embodiment, the operating part 12 and the operating frame 1 are separate and are fixedly mounted on the operating frame 1 through a snap-fit ​​connection. Of course, the operating part 12 can also be integrally formed on the operating frame. The through hole 51 extends parallel in the reciprocating direction. By moving the operating frame 1 laterally along the through hole, the column 11 pushes the cutter head assembly to adjust its height through the slope of the inclined sliding groove section 31, and locks it at the side end of the guide groove 3, i.e., the "L"-shaped locking section or the "7"-shaped locking section, thereby realizing the lateral control of the cutter head assembly height adjustment.

[0015] In this embodiment, several arc-shaped isolation protrusions 14 are provided on the back of the operating frame, away from the driving column 11. These isolation protrusions abut against the shell surface of the cutter head assembly with guide grooves, limiting the distance between the operating frame 1 and the cutter head assembly shell, thereby ensuring the structural stability of the cutter head assembly and the shell, minimizing frictional damping, and reducing noise. In this embodiment, two second isolation protrusions 13 are also provided on the front of the operating frame body to space the operating frame from the inner wall of the shell, allowing the operating part 12 to move smoothly and ensuring the structural stability of the cutter head height adjustment structure.

[0016] Although the present invention has been disclosed above with specific embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope of the appended claims.
