Abstract
Description
Technical Field
[0001] This utility model relates to personal care or medical shavers, and in particular to a reciprocating shaver. Background Technology
[0002] With the continuous development of society and the improvement of people's living standards, individuals are paying more and more attention to their appearance. As a result, various types of shavers have emerged, among which reciprocating shavers are particularly popular. Existing reciprocating shaver heads mainly consist of a stationary blade and a moving blade. The stationary blade has a hair inlet for guiding hair, while the moving blade is fixed to a blade holder that is synchronously linked with the drive mechanism. The high-speed rotation of the drive mechanism causes the blade holder to oscillate back and forth, which in turn causes the moving blade to move horizontally back and forth along the stationary blade to achieve shaving. Current designs typically include a base and a blade holder that supports the stationary and moving blades. The base and blade holder are connected by a spring to form a floating connection. An additional component is needed to limit the movement of the blade holder relative to the base. The overall design is not simple enough and still needs improvement. Summary of the Invention
[0003] In view of this, the present invention provides a reciprocating razor.
[0004] A reciprocating razor includes a razor holder and a blade assembly. The blade assembly is connected to the razor holder. The blade assembly includes a stationary blade and a moving blade. The stationary blade is hollow, forming a cavity. The razor holder includes a moving blade holder and a fixing frame assembly. The moving blade holder is connected to the moving blade and receives power to drive the moving blade to reciprocate. The fixing frame assembly includes an upper seat, a base, and a connecting seat located between the upper seat and the base. The upper seat is connected to the connecting seat. One of the base or the connecting seat is provided with multiple flexible members. A limiting groove is formed around the center of each flexible member. The opening diameter of the limiting groove is smaller than the aperture of the groove body. The other of the connecting seat or the base is provided with a limiting body connected to the flexible member. One end of the limiting body forms a protrusion. The outer diameter of the protrusion is larger than the opening diameter of the groove, allowing the protrusion of the limiting body to extend into the groove body and form a limiting connection with the flexible member. The base is provided with an elastic member that elastically supports the flexible member or the limiting body, allowing elastic floating between the flexible member or the limiting body.
[0005] Preferably, the upper seat extends along the length direction of the moving blade, the connecting seat further includes a connecting seat body, the limiting body is disposed on the connecting seat body, the upper seat forms a ring arm, and the ring arm overlaps the connecting seat body.
[0006] Preferably, the upper seat includes an upper seat frame, and the ring arms are disposed at both ends of the upper seat frame and are formed by extending from the upper seat frame. The cross-section of the ring arms is arch-shaped.
[0007] Preferably, the stationary blade is located inside the two ring arms, and the two ends of the connecting seat extend through the ring arms into the cavities on both sides of the stationary blade.
[0008] Preferably, the upper frame has side walls, and the side walls of the upper frame are provided with slots / holes or protrusions that engage with the connecting seat body, and the connecting seat body is provided with corresponding protrusions or slots / holes to cooperate with them.
[0009] Preferably, at least one of the moving blade or the stationary blade is provided with a guide groove, and a rolling element is provided in the guide groove to reduce the frictional force of the moving blade swinging relative to the stationary blade. The connecting seat is provided with a limiting structure, which limits the rolling of the rolling element to prevent it from detaching from the guide groove.
[0010] Preferably, the limiting structure extends into the guide groove to form a guiding fit.
[0011] Preferably, the connector includes a connector body and a connector arm, wherein the connector arm extends from the connector body and the limiting structure is disposed on the connector arm.
[0012] Preferably, the upper seat and the connecting seat are integrally injection molded.
[0013] Preferably, the upper seat is made of metal or alloy, and the connecting seat is made of plastic.
[0014] Preferably, the cross-section of the upper part of the slot of the flexible member and the cross-section of the protrusion are both tapered, with the upper part being larger than the lower part.
[0015] The beneficial effects of this utility model are as follows: when the protrusion extends into the flexible groove, it is difficult to detach due to the restriction of the groove opening. This structure can quickly complete the installation of the blade assembly and the fixing frame assembly, making the upper seat and the base form a floating connection that is easy to disassemble. Moreover, this structure does not require the setting of other components to limit the floating between the upper seat and the base, making the structural design simpler. The rolling element is used to transform the sliding friction between the moving blade and the stationary blade into rolling friction. Under the frictional resistance, the frictional contact area is small, the temperature rise caused by friction is low, and the frictional current is small, which helps to dissipate heat from the blade assembly and improves the service life of the shaver.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] The present invention will now be further described with reference to the accompanying drawings.
[0032] This utility model provides the following technical solution:
[0033] As attached Figures 1-11 As shown, this application discloses a reciprocating razor, including a razor holder 1 and a blade assembly 2, wherein the razor holder 1 is connected to the blade assembly 2 of the reciprocating razor. The blade assembly 2 is fixed by the razor holder 1. The blade assembly 2 includes a stationary blade 3 and a moving blade 4, both of which are hollow to form a cavity 5, with the moving blade 4 located inside the cavity 5 of the stationary blade 3.
[0034] like Figure 2 As shown, the razor holder 1 includes a movable blade holder 6 and a fixing frame assembly 7. The movable blade holder 6 is connected to the movable blade 4 and receives power to drive the movable blade 4 to reciprocate. This is not an improvement of this application and will not be described in detail here. The fixing frame assembly 7 includes an upper seat 8, a base 9, and two connecting seats 10 located between the upper seat 8 and the base 9. The upper seat 8 is connected to the connecting seats 9. Specifically, both the upper seat 8 and the base 9 extend along the length direction of the movable blade 4. The two connecting seats 10 are installed at both ends of the upper seat 8. One of the base 9 or the connecting seat 10 is provided with a plurality of flexible members 11, and a limiting groove 12 is formed around the middle of the flexible member 11. The diameter of the groove opening 13 of the limiting groove 12 is smaller than the diameter of the groove body 14. The other of the connecting seat 10 or the base 9 is provided with a limiting body 15 connected to the flexible member 11. One end of the limiting body 15 forms a protrusion 16. The outer diameter of the protrusion 16 is larger than the diameter of the groove opening 13, so that the protrusion 16 of the limiting body 15 extends into the groove body 14 and forms a limiting connection with the flexible member 11. The base 9 is provided with an elastic member 17, which elastically supports the flexible member 11 or the limiting body 15, so that the flexible member 11 or the limiting body 15 forms an elastic floating relationship.
[0035] like Figure 2As shown, a flexible member 11 is provided on the base 9, and a limiting body 15 connected to the flexible member 11 is provided on the connecting seat 10. Specifically, multiple flexible members 11 are provided on the base 9 at positions corresponding to the connecting seat 10, forming two groups of flexible members 11. A limiting groove 12 is formed around the middle of each group of flexible members 11. In this embodiment, the upper end of the flexible member 11 protrudes radially to form a claw-like shape, so that the diameter of the groove opening 13 of the limiting groove 12 is smaller than the aperture of the groove body 14. Of course, in specific implementations, this is not a limitation; any implementation that can form a groove opening 13 smaller than the aperture of the groove body 14 is acceptable. Each connecting seat 10 is provided with a limiting body 15, and one end of the limiting body 15 forms a protrusion 16. Specifically, in this embodiment, the protrusion 16 is formed in a state where the size gradually tapers from the limiting body 15 to the end of the protrusion 16. This arrangement facilitates the protrusion 16 to extend into the groove body 14 and connect with the flexible member 11. The outer diameter of the protrusion 16 is larger than the diameter of the groove 13, allowing the protrusion 16 of the limiting body 15 to extend into the groove 14 and form a limiting connection with the flexible member 11. An elastic member 17 is provided within the limiting groove 12, and the elastic member 17 is elastically supported between the limiting groove 12 and the protrusion 16. Specifically, as shown... Figure 3 As shown, in this embodiment, the flexible member 11 is positioned to protrude radially from the slot 13, making the diameter of the slot 13 smaller than the aperture of the groove 14. Therefore, when the protrusion 16 extends into the flexible groove 14, it is restricted by the slot 13 and difficult to detach. This structure allows for quick installation of the blade assembly 2 and the fixing frame assembly 7, enabling the upper seat 8 and the base 9 to form a detachable floating connection.
[0036] In a practical implementation, if the flexible element 11 is located on the connecting seat 10, then the limiting body 15 can be located on the base 9. It is easy to understand that the limiting body 15 can be integrally formed with the base 9 or it can be detached. In order to limit the movement distance between the limiting body 15 and the flexible element 11, the limiting body 15 can also be provided with upper and lower bosses, such as a dumbbell-shaped structure, but this is not a limitation.
[0037] like Figure 1-3 As shown, the connecting seat 10 also includes a connecting seat body 18, with the limiting body 15 disposed on the connecting seat body 18. The upper seat 8 forms a ring arm 19, which overlaps the connecting seat body 18. Specifically, the limiting body 15 is a shaft formed below the connecting seat body 18, and the protrusion 16 is formed at the end of the shaft and protrudes radially. This arrangement improves the smoothness of the assembly of the connecting seat 10 with the limiting groove 12 via the limiting body 15.
[0038] See attached document Figure 5 , 11To facilitate the insertion of the flexible member 11 into the groove 14 for connection between the base 9 and the connecting seat 10, the upper cross-section of the groove 13 of the flexible member 11 and the cross-section of the protrusion 16 are both tapered, with a larger upper section and a smaller lower section. This design facilitates installation and ensures structural stability, as the flexible member is difficult to remove without external force after installation.
[0039] See attached document Figure 3 The upper seat 8 includes an upper seat frame 20, and the ring arms 19 are disposed at both ends of the upper seat frame 20 and extend from the upper seat frame 20. The cross-section of the ring arms 19 is arched. Specifically, the upper seat frame 20 has two parallel sidewalls 21 extending along the length direction of the moving blade 4. The sidewalls 21 of the upper seat frame 20 are provided with slots / holes 22 or protrusions 23 that engage with the connecting seat body 18. The connecting seat body 18 is correspondingly provided with protrusions 23 or slots / holes 22 to cooperate with them. In the embodiments disclosed in this application, the ring arms 19 are arched and connected at both ends of the two sidewalls 21. The ring arms 19 overlap the connecting seat body 18 to form support, and are limited by the slots 22 at both ends of the sidewalls 21 and the protrusions 23 on the connecting seat body 18, so as to realize the detachable connection between the two.
[0040] Specifically, the stationary blade 3 is located inside the two ring arms 19, and the two ends of the connecting seat 10 pass through the ring arms 19 and extend into the cavities 5 on both sides of the stationary blade 3 to support the stationary blade 3.
[0041] As attached Figure 4 Appendix Figure 6-9 As shown, at least one of the moving blade 4 or the stationary blade 3 is provided with a guide groove 24. A rolling element 25 is provided in the guide groove 24 to reduce the frictional force when the moving blade 4 reciprocates at high speed relative to the stationary blade 3. The rolling element 25 is preferably a ball bearing. By using the rolling element 25, the sliding friction between the moving blade 4 and the stationary blade 3 is converted into rolling friction. Under the frictional resistance, the frictional contact area is small, so the temperature rise caused by friction is low, the frictional current is small, and the bottom of the moving blade 4 does not contact the bottom of the stationary blade 3, that is, a certain gap is formed, which helps the heat dissipation of the blade assembly and improves the service life of the shaver.
[0042] like Figure 5As shown, the connecting seat 10 is provided with a limiting structure 26, which limits the rolling of the rolling element 25 to prevent it from disengaging from the guide groove 24. Specifically, the connecting seat 10 also includes a connecting arm 27, which extends from the connecting seat body 18, and the limiting structure 26 is disposed on the connecting arm 27. The limiting structure 26 consists of two protruding structures formed on the connecting arm 27, and the positions of the two protruding structures correspond to the two sides of the guide groove 24, forming at least partial obstruction of the two sides of the guide groove 24, thereby limiting the rolling element. In summary, the main purpose of this design is to prevent the rolling element 25 from disengaging from the guide groove 24, so any design that can achieve this function conforms to the "limiting structure" defined in this application.
[0043] As attached Figure 3 As shown, in a specific implementation, the limiting structure 26 can be inserted into the guide groove 24 to form a guiding fit. Typically, in the prior art, such as... Figure 3 As shown, the guide structure on the moving blade holder 6 is used to guide the moving blade 4. In this application, the guide and limiting structures at both ends of the moving blade 4 can be further implemented. When the protrusion height of the limiting structure 26 is sufficient to extend into the guide groove 24, the limiting structure 26 can both limit the movement of the rolling element and further guide and limit the movement of the moving blade 4. This reduces the vibration of the moving blade 4 during movement, thereby reducing temperature rise and noise, and improving the service life of the shaver.
[0044] In practical implementation, the upper seat 8 and the connecting seat 10 can be integrally injection molded, resulting in a more stable structure. The upper seat 8 is made of metal or alloy, while the connecting seat 10 is made of plastic. This structural design offers higher overall shape precision and a more aesthetically pleasing appearance. The upper seat 8 and the connecting seat 10 can be a fixed unit or, as in this application, separate units; neither affects the use of the razor.
[0045] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
