Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reciprocating blade for an electric shaver, and an object thereof is to provide a reciprocating blade for an electric shaver that can reliably remove beard debris accumulated between the inner blades by washing with water. It is about providing.

In the case of reciprocating electric razor blades in which multiple inner blades fixed to a base come into contact with the outer blade, the spacing between the inner blades is narrow, so the hair that has been shaved off during shaving is and part of the skin fat is the base and inner blade plate.
This builds up and cannot be removed sufficiently even after washing with water.
There has been a problem in that it adheres to the cutting blade, impairs its cutting quality, and also causes bacteria to grow in the beard layer and skin fat, giving off a bad odor and causing discomfort when shaving. Furthermore, when shaving with soap applied to the skin, the soap also adheres to the inner blade and base, aggravating the above problem. The present invention has been made in view of the above problems, and will be described below with reference to the drawings showing embodiments of the present invention. 1 to 5, an electric shaver main body 1 includes a main body case 2 formed of a synthetic resin molded material, a drive section (not shown) housed in the main body case 2, and a reciprocating body driven by the drive section. It is composed of a driving saw 3 to be driven, an inner cutter 4 attached to the driving saw 3, and an outer cutter 5 whose inner surface is in sliding contact with the inner cutter 4. The inner blade 4 is a semicircular inner blade 6 made of stainless steel.
and a base 7 made of a synthetic resin material that supports a plurality of inner blades 6 integrally molded and embedded at a predetermined pitch, and is connected to the drive frame 3 via a joint 8. Wide connecting portions 9 are integrally formed at both ends and the center of the inner cutter blade 6, and the wide connecting portions 9 are connected by ribs 10 that are part of the base 7. The ribs 10 are firmly connected at both ends and in the middle by six connecting ribs 11 that are part of the base 7. An opening 12 is formed in the wide connecting portion 9, and a portion of the closing portion 12 is embedded within one rib. The opening 12 may be a round hole as shown in Figure 5A, a round hole with a part cut out as shown in the opening of Figure 5, or a slit-shaped opening as shown in Figure 5C. The two-dot chain line in the figure indicates the buried position. A communication portion 13 is formed between the inner blade 6 and the base 7,
A blade portion 14, which is a wide connection portion 9 that is not supported by the ribs 10, is disposed within the lotus passage portion 13. The outer cutter 5 is composed of an outer cutter plate 16 in which a large number of hair introduction holes 15 are bored, and an outer cutter base 17 that supports the outer cutter plate 16 in a U-shaped curved state. The hair storage chamber 18 is composed of a main body case 2, an outer cutter plate 16, and an outer cutter base 17.
The power switch 19 is slidably provided on the main body case 2. Next, the operating state will be explained.

When the power switch 19 is operated, the inner blade 4 is reciprocated and the hair introduced from the hair introduction hole 15 is cut. The cut beard and skin fat fall into the beard storage chamber 18 or adhere to the inner cutter blade 6. When water is introduced into the outer cutter 5 and the inner cutter 4 and the water is passed into the beard storage chamber 18, the beard is collected. room 18
The beard shoulders and fatty layer of the skin are washed away. At the same time, when the inner cutter 4 is reciprocated, the water is guided by the base 7 and flows through the opening part 12 of the inner cutter 4, and the water also flows through the lotus passage part 13, so that the inner cutter plate This effectively removes beard debris and skin fat adhering to the base 6 and the base 10. As described above, the reciprocating blade of the electric shaver according to the present invention is an electric shaver in which the reciprocating blade of the electric shaver is shaped and supported so that the weaving parts of the plurality of inner blades that come into sliding contact with the outer blade provided with the hair introduction holes are buried in the base. This reciprocating blade is characterized in that the - part of the opening □ formed at the end of the inner cutter blade is buried in the base, so that the inner cutter blade and the inner cutter base can be removed by washing with water. It has the effect of reliably removing beard debris and fat deposits on the skin, maintaining the outer and inner blades in good cutting condition, and allowing a comfortable shave without bad odor. Furthermore, since a part of the entrance of the inner blade is buried in the base, the inner blade can be firmly fixed to the base without rattling, and the inner blade is in close contact with the outer blade, resulting in sharper cutting. It has the effect of being good.

The simple test drawings in the drawings show an embodiment of the reciprocating blade of the electric shaver of the present invention, and FIG. 1 is an exploded perspective view of the electric shaver main body and the reciprocating blade of the electric shaver, and FIG. Figure 3 is a perspective view of the external appearance of the outer blade and inner blade, Figure 4 is a cross-sectional view of the inner blade with a portion cut away, Figure 5 FIG. 2 is a partially cutaway plan view of the inner blade.
