Description

Technical Field

[0001] The utility model relates to the technical field of shavers, in particular to a rotary shaver with a self-cleaning function. Background Art

[0002] Rotary shavers need to be cleaned before or after use to remove dandruff, dirt and hair residues on the blade head. The traditional cleaning method is to disassemble and then clean manually, which is inconvenient to use. Therefore, some rotary shavers with automatic cleaning functions have emerged. These shavers either use water flow to flush or rely on the moving blade of the blade head to rotate the water flow for cleaning, but both methods cannot provide efficient cleaning effects and still cannot completely remove hair residues and difficult-to-clean dirt. Utility Model Content

[0003] In order to improve the automatic cleaning performance of a rotary shaver, the utility model provides a rotary shaver movable blade with a self-cleaning function.

[0004] The technical solution adopted by the utility model is as follows: a rotary shaver with a self-cleaning function, comprising: a cutter disc having a central hole; at least one circle of blades, integrally arranged on the front of the cutter disc and surrounding the outer circumference of the central hole; a driving member, fixed in the central hole, having a coupling hole for transmission connection with a power shaft of the shaver; at least two rotary arms, located on the back of the cutter disc, extending radially outward from the outer edge of the driving member, and forming a stirring blade structure within the diameter range of the cutter disc.

[0005] Preferably, the rotary arm is in contact with the back side of the cutter disc.

[0006] Preferably, the height of the spiral arm is greater than its thickness.

[0007] Preferably, the outer end of the rotary arm is inclined toward the rotary cutting direction of the blade.

[0008] Preferably, the spiral arm forms a concave liquid-facing surface on one side of the inclined direction.

[0009] Preferably, it also includes: flushing holes, which correspond to the rotary arms one by one and are opened on the cutter disc.

[0010] Preferably, the cutter disc is punched and sheared at the middle diameter to form the blade, and the vacant area left by the punching and shearing forms the flushing hole.

[0011] Preferably, the driving member and the rotary arm are integrally formed by injection molding with the cutter disc as an inlay.

[0012] Preferably, it also includes: an inlay hole, which corresponds one-to-one to the spiral arm and is arranged on the cutter disc near the outer end of the spiral arm.

[0013] On the other hand, the technical solution is as follows: a rotary shaver, comprising: a movable blade as described above; and a blade net corresponding one-to-one to the movable blade.

[0014] Preferably, the movable knife has two circles of blades, and the knife net is correspondingly a double-ring structure having an inner ring surface and an outer ring surface; a T-shaped beard feeding groove is provided on the inner ring surface.

[0015] The utility model has the following beneficial effects: the utility model arranges a rotary arm on the back of the blade disc and connects it to a driving member. When the shaver turns on the cleaning mode, the driving member drives the rotary arm to rotate, thereby generating a stirring effect in the blade head area. This stirring effect can enhance the flow of water, effectively clean the hair residues and dirt on the movable blade and the blade net, and improve the cleaning effect.

[0020] The utility model is further described below in conjunction with the embodiments and drawings.

[0021] In the embodiment, Figure 1~2 The figure shows a rotary shaver with a self-cleaning function, comprising: a blade disc 1 having a central hole 2; at least one circle of blades 3, integrally arranged on the front of the blade disc 1, surrounding the periphery of the central hole 2; a driving member 4, fixed in the central hole 2, having a coupling hole 5 for transmission connection with the power shaft of the shaver; at least two rotary arms 6, located on the back of the blade disc 1, extending radially outward from the outer edge of the driving member 4, forming a stirring blade structure within the diameter of the blade disc 1. In this embodiment, a rotary arm 6 is arranged on the back of the blade disc and connected to the driving member 4. When the shaver is turned on the cleaning mode, the driving member 4 drives the rotary arm 6 to rotate, thereby generating a stirring effect in the blade head area. This stirring effect can enhance the flow of water, effectively clean the hair residues and dirt on the movable blade and the blade net, and improve the cleaning effect.

[0022] In the embodiment, Figure 1~2As shown, the rotary arm 6 is fitted with the back of the blade disc 1. With this structure, the rotary arm 6 can not only play a stirring role, but also play a role in strengthening the support of the blade disc 1, thereby improving the overall rigidity of the moving blade and helping to increase the service life.

[0023] In the embodiment, Figure 1~2 As shown, the height h of the rotary arm 6 is greater than its thickness d, and the outer end of the rotary arm 6 is inclined toward the rotation direction of the driving member 4, that is, the rotary cutting direction of the blade. This design allows the size and angle of the rotary arm 6 to better adapt to the structure of the cutter disc 1, play a better stirring role, thereby enhancing the cleaning force and ensuring thorough cleaning of the moving knife and the knife net.

[0024] In the embodiment, Figure 1~2 As shown, the rotary arm 6 forms a concave liquid-facing surface 7 on one side of the inclined direction. The design of the liquid-facing surface 7 allows the water flow to gather on the moving blade, thereby improving the utilization rate of the water flow; at the same time, a stronger flushing force is formed during the stirring process, which can more thoroughly rinse the blade head.

[0025] In the embodiment, Figure 1~2 As shown, it also includes: a flushing hole 8, which corresponds to the swing arm 6 one by one and is opened in the cutter disc 1. The flushing hole 8 allows the cleaning water flow to smoothly pass through the flushing hole 8 into the movable knife and knife net area, and the flushing hole 8 can also be used to discharge sewage during the cleaning process. Such a design facilitates the cleaning operation and improves the convenience and efficiency of cleaning. In fact, the cutter disc 1 is punched and sheared at the middle diameter to form the blade 3, and the vacant area after punching and shearing simultaneously forms the flushing hole 8. Therefore, there is no need to open a special flushing hole 8, and the function of the flushing hole 8 can be realized by utilizing the original punching and shearing vacancy.

[0026] In the embodiment, Figure 1~2 As shown, the driving member 4 and the rotary arm 6 are an integral injection molded part with the cutter head 1 as an insert. This structure can provide better stability and durability, while simplifying the assembly process and reducing costs.

[0027] In the embodiment, Figure 1~2 As shown, it also includes: an inlay hole 9, which corresponds to the swing arm 6 one by one and is arranged on the cutter disc 1 near the outer end of the swing arm 6. The inlay hole 9 is used to strengthen the fixation of the swing arm 6 during the injection molding process, further strengthen the connection stability of the swing arm 6 and the cutter disc 1, and ensure the firmness and reliability of the overall moving knife.

[0028] In the embodiment, Figure 3As shown, it is a knife net matching the above-mentioned movable knife. Specifically, the movable knife has two circles of blades 3, and the knife net is a double-ring structure with an inner ring surface 10 and an outer ring surface 11; a T-shaped beard inlet groove 12 is provided on the inner ring surface 10. The T-shaped beard inlet groove 12 can make the knife net obtain a larger flow area, which can increase the flushing flow rate, and at the same time can change the flow state of the flushing water, increase the fluidity of the flushing water on the knife net, and also make the flushing water more fully cover and flush the surface of the knife net, which is helpful to flush the residual hair and the dirt that is difficult to clean, thereby improving the effect and efficiency of automatic flushing, and ensuring that the cleaning effect can achieve a more thorough effect.

[0029] Obviously, the above embodiments of the present invention are only examples for explaining the present invention, and are not intended to limit the implementation methods of the present invention. Other obvious changes or modifications derived from the essence of the present invention still fall within the protection scope of the present invention.
