Problems solved by technology

[0003] However, in the above conventional example, the two sides P3 and P4 of the lower end of the vibrating plate 40 are supported by the front and rear support portions 41 at two points. There is a limit when the amplitude vibrates
Therefore, the inner blade of the existing reciprocating electric razor cannot fully satisfy the desire to increase the comfortable shaving sound.

[0023] For example, if figure 2 As shown, the head of the reciprocating electric shaver according to this embodiment is detachably mounted with four independent and freely floating blade heads 21 to 24 . Among them, two auxiliary cutting heads 23, 24 are arranged in the center, and two arch-shaped main cutting heads 21, 22 for fine shaving are respectively arranged on the two outer sides thereof.

[0024] exist figure 2 Among them, two main cutting heads 21, 22 for fine shaving are the same as the prior art, including outer blade 25A, outer blade frame 26A, inner blade 27A, inner blade joint 28A, and outer blade cover 29A, etc.

[0025] In addition, one of the two auxiliary cutting heads 23, 24 includes the arc-shaped fine shaving blade assembly 6, and the other includes a rough shaving blade assembly including the slit blade 1A, the inner blade 3A, and the inner blade joint 4A. 18.

[0026] Next, the fine shaving blade unit 6 constituting the auxiliary blade head 23 will...

no. 2 approach

[0041] In the above-mentioned first embodiment, the central point support structure of the vibrating plate 40 was described, but in this embodiment, as Figure 9 As shown, the support portion 41 of the vibration plate 40 is arranged close to either one of the front and rear sides of the vibration plate 40 to support the lower end side P2 of the vibration plate 40 at one point. In addition, other structures are the same as those of the above-mentioned first embodiment. In this way, even if the support portion 41 is arranged toward one side, the lower opening of the vibrating plate 40 is widened similarly to the first embodiment, and it is possible to obtain an effect that beard scum is less likely to accumulate. Furthermore, by forming the vibrating plate 40 supported at one point on one side, the distance from the point P2 on one side to the protruding piece 42 becomes longer. Therefore, the moment of vibration of the vibrating plate 40 becomes larger, thereby obtaining an eff...

Abstract

An inner blade for a reciprocating electric shaver includes an inner blade body (3) having reverse U-shaped blade sections (30) for sliding along the inner surface of an outer blade (1) to cut hairs,and also has an inner blade joint (4) for supporting the inner blade body (3). The inner blade joint (4) is provided with vibration plates (40) connected to any of the blade sections (30) and producing a shaving sound when hairs are cut, and with a support section (41) for supporting the vibration plates (40). The support section (41) supports one point of each vibration plate (40).

Description

technical field [0001] The invention relates to an inner blade of a reciprocating electric razor, in particular to a structure in which a plurality of vibrating plates are arranged at the joint of the inner blade. Background technique [0002] At present, as the inner edge of the reciprocating electric razor, such as figure 1 As shown, the following structure is known: a vibrating plate 40 is installed on the supporting portion 41 of the inner blade joint 4, and the top of the vibrating plate 40 is connected with any one blade 30 of the inner blade body 3. When shaving beard, the The vibrating plate 40 vibrates, thereby generating a comfortable vibrating sound (shaving sound). [0003] However, in the above conventional example, the two sides P3 and P4 of the lower end of the vibrating plate 40 are supported by the front and rear support portions 41 at two points. There is a limit when it comes to amplitude vibrations. Therefore, the inner blade of the conventional recipr...
