Description
Technical Field
The utility model relates to a shaver, in particular to an electric shaver head.
Background
The electric shaver is a small household appliance widely used by people, and has the characteristics of comfortable, safe, convenient and quick use. The working principle of an electric shaver is essentially the shearing principle; the blade (also called movable blade) on the cutter head is closely matched with the inner surface of the cutter net (also called static blade), beard and hair extend into the cutter net hole groove from the outside of the cutter net, and the blade rotates at a high speed or reciprocates to form relative motion with the cutter net, so that the extending beard and hair are cut off.
Most of the existing electric shavers are two cutting rings, namely, a plurality of blades on a cutter head are arranged into two annular inner and outer rings which are respectively matched with two net rings on a cutter net to cut beards and hairs. The use experience of consumers shows that the shaving efficiency needs to be improved, and the shaving time needs to be reduced; improvements by those skilled in the art are needed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provide a three-ring cutter head of an electric shaver, which can effectively improve the shaving efficiency under the matching of corresponding cutter nets so as to meet the requirements of people.
The technical scheme provided by the utility model is as follows:
a three-ring cutter head of an electric shaver; the shaver comprises a blade assembly and a transmission universal joint, wherein the top end of the transmission universal joint is connected with the blade assembly, and the bottom end of the transmission universal joint is detachably connected with a shaver motor shaft; the method is characterized in that: a plurality of third annular cutting edges are annularly distributed between the first annular cutting edges and the second annular cutting edges; a plurality of third ring cutting edges are all in punching press forms on the second hardware to a plurality of third ring cutting edges rotate the shearing circle that forms and be less than the inner circle.
A plurality of third ring cutting edges and a plurality of second ring cutting edges are all distributed on the outer circumference edge of the second hardware.
And in the plurality of third ring cutting edges, every two adjacent third ring cutting edges are arranged at equal intervals.
The utility model has the beneficial effects that: because the third cutting ring is additionally arranged in the original two cutting rings (the outer ring and the inner ring), the cutting contact surface with beard hair is obviously increased, the shaving speed is accelerated, and the shaving time is shortened; the third cutting ring is also effective in cutting short hair, even for shaving heads.

Detailed Description
The following further description is made with reference to the embodiments shown in the drawings.
Three-ring cutter heads of the electric shaver shown in the attached drawings; the transmission universal joint comprises a cutting edge assembly and a transmission universal joint, wherein the top end of the transmission universal joint is connected with the cutting edge assembly, and the bottom end of the transmission universal joint is detachably connected with a shaver motor shaft, and the cutting edge assembly comprises a first hardware part and a second hardware part, wherein a plurality of first annular cutting edges 1 are manufactured on the first hardware part, and a plurality of second annular cutting edges 2 are manufactured on the second hardware part; a plurality of first ring cutting edges 1 are used as outer rings and are annularly distributed on a first hardware; a plurality of second ring cutting edge 2 is as the inner circle, and the annular distributes on the second hardware.
The structure is similar to the existing shaver head.
The improvement of the utility model lies in that: a plurality of third annular cutting edges 3 are annularly distributed between the first annular cutting edges and the second annular cutting edges; the third ring cutting edges are formed on the second hardware in a stamping mode, and the third ring cutting edges and the second ring cutting edges are integrally formed in a stamping mode; and the shearing rings formed by the rotation of the plurality of third ring blades are smaller than the shearing rings formed by the rotation of the plurality of second ring blades, so that the area with the shearing function is increased. As can be seen from the figure: the third ring cutting edges are the same as the second ring cutting edges and are distributed on the outer circumferential edge of the second hardware; and during processing, the second ring blade and the second ring blade are punched and formed together, and then thermal treatment quenching and tempering and grinding processing are carried out.
In the plurality of third ring cutting edges, every two adjacent third ring cutting edges are arranged at equal intervals; and the number of third ring blades is significantly less than the number of second ring blades. Therefore, the distance between the adjacent third ring cutting edges is larger than that between the adjacent second ring cutting edges; obviously, longer hairs can easily enter the third cutting rings formed by the third ring blades for cutting, and the cutting effect is improved.
After the two hardware parts are punched, the two hardware parts are subjected to heat treatment and cutting edge grinding treatment, are connected into a whole through an injection molding and rubber coating process (the existing mature process), and are assembled into a cutter bit together with a transmission universal joint.
As can be seen from the figure: the transmission universal joint is formed by an upper cover 4, a spring 5 and a connecting piece 6; three hooks of the connecting piece 6 are hooked on the steps on the inner wall of the upper cover, and the spring 5 is arranged between the connecting piece and the upper cover and used for adjusting the height of the upper cover in use.
As can be seen from fig. 3, when the blade assembly is assembled with the transmission universal joint, the edge protrusions (the edge protrusion 1-1 of the first hardware and the edge protrusion 2-1 of the second hardware) of the inner circumferences of the two hardware are fixed by encapsulating through an injection molding process, and can be embedded into the embedding opening 4-1 flash-opened on the outer circumference of the upper cover, so that the blade assembly is assembled with the transmission universal joint. The structure is the same as that of the prior shaver head.
After the utility model is improved, the matched knife net is also correspondingly changed; since the improvement of the knife net does not belong to the knife head, it is not described here.
