INVENTION CONTENT
[0003] The utility model aims at overcoming the deficiencies of the above background technical, provide electric shaver three-ring multifunctional cutter head, the cutter head should have hairdressing function and shaving function simultaneously, to save time, improve efficiency, while facilitating people's life.
[0004] The technical scheme provided by the utility model is:
[0005] A kind of electric shaver three-ring multifunctional cutter head;Including the transmission universal joint of bottom end detachable connection razor motor shaft and the cutter blade assembly connected in transmission universal joint top;The cutter blade assembly includes the first metal piece and the second metal piece connected as a whole, first metal piece is distributed with a plurality of first ring knives in annular form so as to form the shearing outer circle of cutter head, and the second metal piece is distributed with a plurality of second ring knives in annular form so as to form the shearing inner circle of cutter head;Characterized in that: a plurality of third ring knives distributed in annular form are further provided on the second metal piece;The flange of a plurality of notches formed on the second metal piece one side, forms the plurality of third ring knives.
[0006] The flange protrudes and is inclined to the plane of the second metal piece, and also forms an acute angle with the plane of the second metal piece.
[0007] The inclination direction of the flange is consistent with the tangent direction when the flange rotates.
[0008] The first metal piece and the second metal piece are coaxially connected to the transmission universal joint, and the shearing circle formed by the rotation of the plurality of second ring knives is smaller than the shearing circle formed by the rotation of the plurality of first ring knives.
[0009] The plurality of first ring knives are all formed by punching on the outer circumferential edge of the first metal piece;The plurality of second ring knives are all formed by punching on the outer circumferential edge of the second metal piece.
[0010] The utility model discloses beneficial effect is: originally only a few first ring knives and a few second ring knives form two shearing circles for shaving, after the shearing that a few third ring knives are additionally formed, have the hairdressing function, and thus accelerate the shearing speed of the beard hair, reduce the shaving time, and can also effectively cut the hair, even for shaving.

[0017] DETAILED DESCRIPTION
[0018] The following further illustrates in conjunction with the embodiment shown in the drawings.
[0019] The three-ring multifunctional cutter head of the electric shaver shown in the drawings includes a blade assembly and a transmission universal joint detachably connected between the blade assembly and the shaver motor shaft (the top end of the transmission universal joint is connected with the blade assembly, and the bottom end is connected with the shaver motor shaft; the shaver motor shaft is omitted in the drawing), and the blade assembly includes a first metal piece provided with a plurality of first ring knives to form a shearing outer ring and a second metal piece provided with a plurality of second ring knives to form a shearing inner ring; the first metal piece and the second metal piece are both disc-shaped planes. The plurality of first ring knives are annularly distributed on the outer circumferential edge of the first metal piece and formed by the flanging after stamping and folding upward; the plurality of second ring knives are annularly distributed on the outer circumferential edge of the second metal piece and formed by the flanging after stamping and folding upward; the above structure is similar to the existing shaver cutter head.
[0020] The improvement of the utility model lies in: a third shearing ring is additionally arranged, the third shearing ring is formed by a plurality of third ring knives 3 arranged in a ring shape; as shown in the figure: the shearing ring formed by the plurality of third ring knives 3 is coaxially arranged with the shearing inner ring formed by the plurality of second ring knives, and the diameter of the shearing ring formed by the rotation of the plurality of third ring knives is smaller than the diameter of the shearing inner ring formed by the rotation of the plurality of second ring knives.
[0021] As shown in the figure: the second metal piece has a plurality of notches 2-2 formed by punching on the plane, the metal material punched out of the notch is still connected to one side of the notch (the other three sides are disconnected) and forms a tab, and a blade is formed at the top end of the tab, thereby forming the plurality of third ring knives 3.
[0022] The tab is inclined to the plane (i.e. the disc-shaped plane) of the second metal piece and forms an acute angle, preferably 60 degrees; the inclination direction of the tab is also consistent with the tangential direction of the rotation of the tab; in this way, the third ring knife has sufficient rigidity during shearing operation.
[0023] In addition, the number of the plurality of third ring knives is obviously less than the number of the plurality of second ring knives, but the distance between two adjacent third ring knives is obviously smaller than the distance between two adjacent second ring knives. Obviously, longer hair is more likely to enter the shearing ring formed by the plurality of third ring knives for shearing, thereby ensuring the hair shearing effect.
[0024] After the punching of the two metal pieces is completed, heat treatment, blade grinding processing and injection molding are performed, and then the blade assembly is formed by combining the two metal pieces, and then the blade assembly is assembled with the transmission universal joint to form the blade head.
[0025] As shown in the figure: the transmission universal joint is formed by a seat body 4, a connecting piece 5 and a spring 6; the bottom end of the connecting piece 5 is used for connecting the razor motor shaft, and three hooks arranged in the circumferential direction at the bottom end are respectively inserted into three fan-shaped grooves 4-1 in the inner wall of the seat body and hook the steps of the fan-shaped grooves; the spring is arranged between the connecting piece and the seat body and applies a top pressure to the two, for adjusting the distance between the seat body and the blade net during work.
[0026] As shown in the figure: Figure 6 It can be seen that when the blade assembly and the transmission universal joint are assembled, the plurality of grooves (the first metal piece groove 1-1 on the inner circumferential edge of the first metal piece and the second metal piece groove 2-1 on the inner circumferential edge of the second metal piece) of the two metal pieces can be combined and fixed by injection molding with the plurality of blocking strips 4-2 (the blocking strips are formed by a plurality of long grooves 4-3 arranged at intervals and discontinuously extending in the circumferential direction) opened on the outer circumferential surface of the seat body, thereby realizing the assembly of the blade assembly and the transmission universal joint. This structure is the same as the existing razor head structure.
[0027] The utility model discloses an improved cutting net, which is characterized in that the cutting net is provided with a plurality of cutting blades arranged in a staggered manner and a plurality of cutting blades arranged in a parallel manner.
