Description

Technical Field

[0001] The utility model belongs to the technical field of shavers, and in particular relates to a shaving head assembly of an open rotary electric shaver and a rotary shaver. Background Art

[0002] The outer wall of the existing rotary single-ring shaving head is high, and a core shaft for rotation and positioning is set in the center of the blade net. The core shaft is small in size, and the stamping is complicated and the dimensional accuracy is difficult to ensure. The mesh teeth of the blade net need to be processed in a special process after stamping. The processing procedures are numerous, the production cost is high, and the efficiency is low. At the same time, the existing blade net components have an outer wall, which makes it slow for the beard to enter the mesh seam. Because the outer wall is high, more raw materials are required and the material utilization rate is low. Therefore, the existing razor sets the blade net into an open structure. The lubricating oil of the shaving head assembly with an open structure is not easy to store during use, and the desired lubrication effect cannot be achieved, and the number of oiling times is increased. Summary of the invention

[0003] In view of the problems existing in the above background technology, the purpose of the utility model is to provide an open rotary electric shaver shaving head assembly and a rotary shaver, which can maintain lubrication well and reduce the number of oiling times.

[0004] The technical solution adopted by the utility model is:

[0005] A shaving head assembly of an open rotary electric shaver comprises a blade net and a rotary blade, wherein the periphery of the rotary blade is located within the projection of the periphery of the blade net, the periphery of the blade net is provided with open mesh teeth, and the lower surface of the blade net is provided with an oil storage tank located at the inner end of the mesh teeth and facing inward. The oil storage tank of the utility model can store a certain amount of oil, which can provide oil for the use of the product and maintain lubrication on the one hand, and the stored oil can be used for a longer time and reduce the number of times of oiling.

[0006] Furthermore, the outer end of the oil storage tank is a tooth-shaped structure.

[0007] Furthermore, the number of teeth of the toothed structure is consistent with the number of teeth of the mesh teeth, and the tooth shapes are arranged in a one-to-one correspondence.

[0008] Furthermore, a safety distance is provided between the outer end of the rotating blade and the outer end of the knife net. The outermost end of the cutting edge of the rotating blade of the utility model maintains a certain safety distance from the outermost end of the knife net, which prevents the blade from shaving the skin during the rotation process, and on the other hand, within this safety distance, the clustering openings between the mesh teeth of the knife net can gather a certain amount of hair, which is convenient for the blade to cut quickly.

[0009] Furthermore, the safety distance ranges from 0.2 to 1 mm.

[0010] Furthermore, a sinking structure is provided at the center of the cutter net, and a central fixing member is installed in the sinking structure. The lower part of the central fixing member has a round shaft for positioning with the driving connecting member.

[0011] Furthermore, the rotary blade is connected to the driving connecting member through a connecting plate.

[0012] Furthermore, both the driving connecting member and the central fixing member are made of plastic.

[0013] The present utility model also discloses a rotary shaver, which includes the shaving head assembly of the open-type rotary electric shaver described in any one of the above technical solutions.

[0014] Compared with the prior art, the remarkable advantages of the present utility model include: the oil storage tank can store a certain amount of oil, on the one hand, providing oil for the use of the product to maintain lubrication, and on the other hand, the stored oil can be used for a longer time, reducing the frequency of oiling.

[0028] Embodiment 1

[0029] Refer to Figures 1-8, this embodiment provides a shaving head assembly for an open rotary electric shaver, including a knife net 1 and a rotary blade 3. The periphery of the rotary blade 3 is located within the projection of the periphery of the knife net 1. An open net tooth 6 is provided on the periphery of the knife net 1. An oil storage tank 9 is provided on the inner side of the inner end of the net tooth 6 on the lower surface of the knife net 1. The oil storage tank 9 of the present utility model can store a certain amount of oil. On the one hand, it provides oil for the use of the product to maintain lubrication. On the other hand, the stored oil can be used for a longer time, reducing the number of times of oiling.

[0030] The outer end of the oil storage tank 9 in this embodiment is a toothed structure 10. The number of teeth of the toothed structure 10 is the same as that of the net tooth 6, and the tooth shapes are arranged in one-to-one correspondence. Of course, the number of teeth of the toothed structure 10 can also be less than that of the net tooth 6.

[0031] A safety distance 8 is provided between the outer end of the rotary blade 3 and the outer end of the knife net 1 in this embodiment. The outermost end of the cutting edge of the rotary blade 3 of the present utility model and the outermost end of the knife net 1 maintain a certain safety distance. On the one hand, it prevents the blade from scratching the skin during rotation. On the other hand, within this safety distance, the gathering port between the net teeth 6 of the knife net 1 can gather a certain amount of hair, facilitating the blade to cut quickly. The range of the safety distance 8 is 0.2 - 1 mm.

[0032] A sinking structure 7 is provided at the center of the knife net 1 in this embodiment. A center fixing member 2 is installed in the sinking structure 7. The lower part of the center fixing member 2 has a round shaft 11 for positioning with the driving connecting member 5. The sinking structure 7 also plays a role in strengthening the knife net 1. The connection between the round shaft 11 and the driving connecting member 5 is equivalent to the cooperation of a shaft and a shaft sleeve.

[0033] The rotary blade 3 in this embodiment is connected to the driving connecting member 5 through a connecting plate 4. Both the driving connecting member 5 and the center fixing member 2 are made of plastic. Specifically, the driving connecting member 5 can be connected to the connecting plate 4 by injection molding, and the connecting plate 4 and the rotary blade 2 can be combined by riveting.

[0034] The oil storage tank of the present utility model can store a certain amount of oil. On the one hand, it provides oil for the use of the product to maintain lubrication. On the other hand, the stored oil can be used for a longer time, reducing the number of times of oiling.
