Description

A kind of rotary electric shaver cutting blade

Technical field

The utility model relates to electric shaver technical field more particularly to a kind of rotary electric shaver cutting blades.

Background technique

Rotary electric shaver in the running moving knife blade need to provide certain shearing force guarantee smoothly will Beard is cut, while when knife foot needs stronger rigidity to guarantee shearing, and knife foot, which will not generate shake, to be caused to shave effect reduction, and Existing shaver knife foot mostly uses greatly a bending and molding, and knife foot and cutting edge face shape are in an angle, it is difficult to take into account existing conjunction The shearing anterior angle of reason, and can guarantee enough knife foot intensity, this cutting blade knife foot head that we design devises a folding Curved, can allowing knife heel portion and cutting edge face shape in this way, knife foot head and cutting edge face form another angle in an angle, can Guarantee that knife foot intensity can be formed again and relatively reasonably shears anterior angle.

Summary of the invention

(1) technical problems to be solved

The purpose of this utility model seeks to overcome disadvantages mentioned above, it is desirable to provide a kind of rotary electric shaver moving knife Piece.

(2) technical solution

In order to achieve the above objectives, the rotary electric shaver cutting blade of the utility model, including matrix, it is arranged in matrix Raise upward outer ring knife foot and the inner ring knife foot on matrix of extension；The outer ring knife foot includes the first blade part and first Support portion, the inner ring knife foot include the second blade part and the second support portion；Wherein, the first blade part and the second blade part with Horizontal direction is in 30 ° ~ 40 ° of angle, the first support portion and the second support portion and horizontal direction is in 50 ° ~ 60 ° of angle.

Further, knife foot reinforcing rib is equipped between second support portion and matrix.

Further, first blade part and the second blade part are all provided with fluted.

Further, every 3 outer rings knife foot is axially evenly arranged at least 3 groups of knife groups in matrix extension as a knife group.

Further, the outer ring knife foot quantity and inner ring knife group quantity ratio are (1.5-2): 1.

Further, outer ring knife foot quantity and inner ring knife group quantity ratio are 9:5.

A kind of cutter head of rotary electric shaver, including knife net and plastic fastening, knife net and plastic fastening it Between be equipped with blade by adopting the above technical scheme.

(3) beneficial effect

Compared with prior art, the technical solution of the utility model, which has the advantage that, has better shear effect, together When enhance the support strength of whole knife foot, while reducing calorific value；Pass through the reasonable Arrangement to Internal and external cycle knife foot, Ji Nengti High shear efficiency, and the positioning and plate armour of energy reserved space technical process easy to produce.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the rotary electric shaver cutting blade of the utility model；

Fig. 2 is the angle schematic diagram of the knife foot of the utility model rotary electric shaver cutting blade；

Fig. 3 is the structural schematic diagram of cutter head made of the utility model rotary electric shaver cutting blade.

Wherein, 1- matrix, 2- inner ring knife foot, the outer ring 3- knife foot, the second blade part of 21-, the second support portion of 22-, 31- first Blade part, the first support portion of 32-, 4- knife net, 5 knife foot reinforcing ribs, 6- groove, 7- plastic fastening.

Specific embodiment

With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.

As shown in Figure 1 to Figure 3, the rotary electric shaver cutting blade of the utility model, Internal and external cycle knife foot 3 are all from base It is obtained on body 1 by repeatedly molding, is an entirety with matrix 1, has the advantage that in this way: saving material, integrated molding is kept away Exempt from repetitive positioning accuracy forfeiture.

The outer ring knife foot 3 of the application includes the first blade part 31 and the first support portion 32, and the inner ring knife foot 2 includes second Blade part 21 and the second support portion 22；Wherein, the first blade part 31 and the second blade part 21 and horizontal direction are in 30 ° ~ 40 ° Angle, with reference to mechanical analysis and through repeatedly research test, moving knife shearing anterior angle can obtain very well at 30 °~40 ° when shaving Shear effect, the first support portion 32 and the second support portion 22 are in 50 ° ~ 60 ° of angle with horizontal direction, can be obtained relatively strong Support force, effectively ensure that knife foot intensity, specific configuration can be found in described in Fig. 2, blade shear when provided by base shaft Power decomposition at: the pressure F1 downward to moving knife and to butt to shearing force F2；

F1 is bigger, and frictional force is bigger, and energy consumption is got higher, and calorific value is big；

F2 is bigger, and shearing force is bigger, sharper.

By physical equation f2=Fcos α so can obtain that angle [alpha] is smaller, then f2 is bigger.

Show that 2 quantity of inner ring knife foot is fewer than outer ring knife foot 3 by actual test, in conjunction with wire side Internal and external cycle working portion Area and inside and outside cutting ring foot real work partial width, outer ring number with the ratio of inner ring number be compared with 1.5-2:1 is it is reasonable Value, it is preferred that the present embodiment setting ratio is that 9:5(is equivalent to 1.8:1).

In the present embodiment, the every 3 knife feet of outer ring knife foot 3 are 1 group, and at least 3 groups of setting can improve totally in this way 9 blade Shear efficiency, and the positioning and plate armour of energy reserved space technical process easy to produce.

In the present embodiment, it is equipped with knife foot reinforcing rib 5 between the second support portion 22 and matrix 1, effectively enhances knife foot bending part The intensity divided.

First blade part 31 and the second blade part 21 are equipped with head recess 6, the groove 6 ensure cutting edge strength and effectively Under the premise of shear effect, reduce the contact area of moving knife and stationary knife, reduce frictional force, have the advantage that: electric current increases Value reduces, frictional heating quantitative change is low, and temperature increase reduces.

Naturally, knife has been made in the blade being equipped between knife net 4 and plastic fastening 7 by adopting the above technical scheme Head has above-mentioned all advantages, and cutter head structure is referring to Fig. 3.

To sum up, the rotary electric shaver cutting blade of the application, has better shear effect, while enhancing entirety The support strength of knife foot, while reducing calorific value；By the reasonable Arrangement to Internal and external cycle knife foot, shear efficiency can be improved, The positioning and plate armour of energy reserved space technical process easy to produce again.

In conclusion above embodiment is not the restricted embodiment for being the utility model, the technology of all this fields The modification or equivalent deformation that personnel are carried out on the basis of the substantive content of the utility model, in the skill of the utility model Art scope.
