Embodiment 1

[0028] Such as Figure 1-3 As shown, a kind of ceramic razor tool of the present embodiment comprises a ring piece 3, an inner ring blade set 2, an outer ring blade set 4, a blade base 1, the inner ring blade set 2, the outer ring blade set 4 Consists of at least one blade 5 respectively, the bottom inside of the blade 5 of the outer ring blade set 4 is connected with the outer ring wall of the ring piece 3, the bottom outside of the blade 5 of the inner ring blade set 2 is connected with the ring piece 3, the inner ring wall of the inner ring blade set 2 is connected to the bottom inner side of the blade 5 of the inner ring blade set 2 and the blade base 1, and the top of the blade 5 is provided with a blade edge, and the blade 5 is made of ceramic material.

[0029] In this embodiment, the reliable connection between the blade 5 and the blade base 1 is realized through the reinforcement structure of the inner ring blade group 2-annular piece 3-outer ring blade group 4, which...

Embodiment 2

[0040] The structure of a ceramic shaver cutter in this embodiment is the same as that in Embodiment 1, so it is not redundant here.

[0041] The differences in this example are:

[0042]The ceramic material in this embodiment is a zirconia ceramic material, comprising the following raw materials in mass fractions: 80 parts of nano-zirconia, 14 parts of alumina, 9 parts of aluminum borate whiskers, 6 parts of yttrium oxide, 3 parts of kaolin, 15 parts Titanium carbide.

[0043] It can be prepared by the following steps: (1) ball milling: ball milling and mixing nano zirconia, alumina, yttrium oxide, kaolin, and titanium carbide; (2) mixing: adding 550 parts by weight of water, 1.8 parts by weight of coupling agent, 1.5 parts by weight of 1 part of binder, 4 parts of dispersant and aluminum borate whiskers, stirred and mixed for 28 minutes, spray-dried to obtain granules; (3) hot pressing: extruding the granules, sending them into the calciner for two sinterings, and one sinte...

Embodiment 3

[0045] The structure of a ceramic shaver cutter in this embodiment is the same as that in Embodiment 1, so it is not redundant here.

[0046] The differences in this example are:

[0047] The ceramic material in this embodiment is a zirconia ceramic material, comprising the following raw materials in mass fractions: 86 parts of nano-zirconia, 16 parts of alumina, 10 parts of aluminum borate whiskers, 8 parts of yttrium oxide, 4 parts of kaolin, 20 parts Titanium carbide.

[0048] It can be prepared through the following steps: (1) ball milling: ball milling and mixing nano-zirconia, alumina, yttrium oxide, kaolin, and titanium carbide; (2) mixing: adding 500 parts by weight of water, 0.1 parts by weight of coupling agent, and 0.2 parts by weight of 1 part of binder, 3 parts of dispersant and aluminum borate whiskers, stirred and mixed for 20 minutes, spray-dried to obtain granules; (3) hot pressing: extrude the granules, send them into the calciner for two sintering, and once...

Abstract

The invention relates to the technical field of shaver cutters and in particular to a ceramic shaver cutter. The ceramic shaver cutter comprises a circular ring piece, an inner ring blade set, an outer ring blade set and a blade base. The inner ring blade set and the outer ring blade set are each composed of at least one blade. The inner side of the bottom of each blade of the outer ring blade set is connected with the outer ring wall of the circular ring piece. The outer side of the bottom of the each blade of the inner ring blade set is connected with the inner ring wall of the circular ring piece. The inner side of the bottom of each blade of the inner ring blade set is connected with the blade base. The top end of each blade is provided with a blade point and each blade is made of a ceramic material. According to the shaver cutter, the structure is improved, the double-ring blades are reinforced through the circular ring piece, the problem that a shaver is not resistant to impact when a ceramic blade serves as a cutter is solved, meanwhile the traditional double-ring blades are maintained, and industrial production is further facilitated; and by the adoption of a shaver adopting the ceramic cutter, it is tested that the a cutter bit is still free of fragments or cracks when the shaver freely falls off 100 times at the height of 1.5 m.

Description

technical field [0001] The invention relates to the technical field of shaver cutters, in particular to a ceramic shaver cutter. Background technique [0002] In the prior art, the razors of rotary shavers are mostly made of metal materials, and the cutter head is in a Y-shaped structure. However, metal materials are used as blades. After a period of use, metal materials are easily worn out, causing users to shave. Sometimes there are bad phenomena such as endless shaving, beard pulling, and poor sharpness. The metal steel cutter head is easy to rust. After rusting, the friction between the cutter nets is increased, the sharpness of cutting is reduced, the load power is increased, and the service life of the product is affected. [0003] Ceramic materials are used as knives, ceramic knives have extremely high hardness, their wear resistance is 60 times that of metal knives, they are almost never worn, and their sharpness is more than ten times that of metal knives. , Fragm...
