Description

[Detailed description of the invention] 〔Technical field〕 The present invention relates to an electric shaver.

[Background technology]

Conventionally, there have been electric shavers that have rotatable blades attached to a razor body that has a built-in motor, so that when in use the blades are tilted relative to the razor body, and when not in use they are in an upright position. (For example, Japanese Patent Application Laid-open No. 48-8907
Q).

This electric shaver has the advantage of being easy to use because the blade can be placed in an inclined position when in use, and easy to store since the blade can be placed in an upright position when not in use.

However, with this electric razor, it was necessary to change the posture of the blade by rotating the blade by hand, so each time it was used, the blade had to be rotated to the tilted position and then returned to the royal position. However, the disadvantage is that the operation is cumbersome.

Also, when rotating the blade, it is easy for the fingers to touch the blade of the blade,
There was also the risk that the blade could be deformed by fingers.

[Purpose of the invention]

An object of the present invention is to provide an electric shaver that eliminates the trouble of rotating the blade, improves usability, and prevents the blade from being erroneously deformed.

[Disclosure of the invention]

The electric shaver of the present invention includes a razor body having a built-in motor, and a razor body provided with the razor body so as to be rotatable between a tilted position and an upright position with respect to the razor body. A blade section is operated by the operation of a motor, and the razor body is provided with a blade section that is provided on the razor body and rotates the blade section to the tilted position in conjunction with an ON operation in which the motor is put into an operating state and the motor is brought into a stopped state. and a switch having a switch handle that rotates the blade portion to the royal position in conjunction with the off operation.

According to the configuration of the present invention, the blade part is rotated in conjunction with the on and off operations by operating the switch handle, so the blade part is rotated each time the electric shaver is used and stored, unlike the conventional method. This eliminates the trouble of manually deforming the blade, which improves usability and prevents the blade from being accidentally deformed by fingers.

Embodiment An embodiment of the present invention will be described with reference to FIGS. 1 to 4. That is, the electric shaver of which this reciprocating electric shaver is an example has a razor main body 1 with a built-in motor (not shown), a state shown in FIG. Figure 4(a)

The blade part 2 is rotated to the tilted position in conjunction with an ON operation in which the motor provided in the razor body 1 is in an operating state, and in conjunction with an OFF operation in which the motor is in a stopped state. and a switch (not shown) having a switch handle 3 for rotating the blade portion 2 to the upright position.

The razor main body 1 is formed into a rectangular box shape by fitting two housings 16 and 17, and has an opening 15 on the side where the blade portion 2 is attached. A storage battery, a motor, and a reciprocating drive converter (not shown) are sequentially built in from the side opposite to the opening 15 inside the razor main body l toward the opening 15, and the output section 5 of the reciprocating drive converter is exposed to the opening 15. , and a direction Y perpendicular to the reciprocating direction X of the output section 5
A drive bushing 4 is pivotally supported on the output part 5 by a pin 6 so as to be rotatable, and protrudes from the razor body 1, and the drive bushing 4 has a built-in spring (not shown).

The blade portion 2 has a blade mounting base 7. It consists of an inner blade body 8 and an outer blade body 9.

The blade mount 7 has an insertion hole 10 formed in the center, a spring-supported lock pin 1) protruding from both end faces, and support pieces 12 hanging down from both ends in the same direction as the insertion hole 10. This support piece 12 has a dogleg-shaped groove 13 having an opening at its lower edge, and a shaft bearing hole 14 at the root side of the support piece 12 . The support piece 12 of the blade mount 7 is inserted through the opening 15 of the razor body 1, and the set screw 18 for connecting and fixing the housing 16.17 is screwed into a nut (not shown) embedded in the housing 16.17. A shaft 19 protruding from the tip of the screw 18 passes through the shaft bearing hole 14 of the support piece 12, whereby the blade mount 7 is rotatably mounted in the same direction as the Y direction.

The inner cutter body 8 includes an inner cutter frame 21 having a drive element 20 on the lower surface of the central part, and a large number of inner cutter frames arranged in rows in the same direction as the reciprocating direction X on the upper surface of the inner cutter frame 21. The drive element 20 is passed through the insertion hole 10 of the blade mount 7, fitted into the drive bush 4, and supported by a spring inside the drive bush 4.

The outer cutter body 9 has an outer cutter 24 stretched over an outer cutter frame 23, and can be freely attached to and detached from the blade mount 7 by engaging lock bins 9 inside the inner sides of both ends of the outer cutter frame 23 (not shown). mounted on. When the outer cutter frame 23 is attached to the blade mount 7, the inner cutter 22 comes into contact with the back surface of the outer cutter 24.

Here, the state in which the blade part 2 is tilted with respect to the razor body 1 is such that the direction perpendicular to the blade surface of the outer cutter 24 of the blade part 2 is relative to the longitudinal direction of the razor body 1 (see FIG. 4). so that the angle θ
It is in a state of tilted posture, and the blade part 2 is in the state of the razor body 1.
When the blade is in an upright position, the direction perpendicular to the blade surface of the outer cutter 24 of the blade section 2 is the fourth direction with respect to the longitudinal direction of the razor body 1.
As shown in figure tal, they are in the same orientation. 1 The switch (not shown) is attached to the housing 1 of the razor body 1.
A switch handle 3 for operating a switch is provided on the inside of the front side of the razor body 1 and is slidably provided on the razor body 1.

The switch handle 3 consists of a handle knob 25 and a switch lever 26 inside the razor body 1, as shown in FIG. The handle knob 25 is arranged so as to be slidable toward and away from the opening 15 on the surface of the housing 16, and has an engaging protrusion 28 inserted into the interior through a hole 27 formed in the housing 16. The switch lever 26 has a substantially U-shape as shown in FIG. 3, and is slidably supported in a groove (not shown) formed on the inner surface of the razor body 1. This switch lever 26 has fitting notches 30 formed on the side edges of both side pieces 29 to engage with the engagement protrusions 28, and outward protrusions 31 on both side pieces 29 that are slidably engaged with the dogleg-shaped grooves 13. is forming.

Note that 32 is a trimmer.

FIG. 4 shows the operating state of this electric shaver.

That is, in figure ta), the switch handle 3 is in the off state, the handle knob 25 of the switch handle 3 is at the lowest position A away from the blade part 2, and the switch lever 2 is in the OFF state.
Since the outward protrusion 31 of No. 6 is located at the lowest position of the dogleg groove 13, the blade portion 2 is in an upright position. Further, the motor does not operate because the switch handle 3 is in the OFF state, and the inner cutter 8 of the blade portion 2 also does not operate. Therefore, the blade part 2 is stored, transported, stored, etc. in an upright, unused state.

4th opening) is in the state of using the razor, and the handle knob 25 of the switch handle 3 is moved to the position 1ffiB on the blade part 2 side.
When the switch handle 3 is slid to the on position, the switch handle 3 is turned on and moved to the on state. At this time, the outward protrusion 31 of the switch lever 26 slides inside the dogleg-shaped groove 13 and is located at the center of the constriction of the dogleg-shaped groove 13, so that the blade mount 7 is moved to the shaft 19.
The blade part 2 rotates in the same direction as the direction Y and tilts, and the blade part 2 is in a tilted position. Further, since the motor is operated by the operation of the switch, the inner cutter frame 21 of the blade section 2 is reciprocated via the drive bush 4, and the outer cutter 2'4 and the inner cutter 22 cooperate to bring the razor into use. Furthermore, when the handle knob 25 of the switch handle 3 is slid from this on state to the side opposite to the blade part 2, the off action is performed, the blade part 2 rotates back to the upright position, and the motor stops operating. .

According to this embodiment, the blade part 2 is rotated in conjunction with the on and off operations by operating the switch handle 3, so the blade part 2 is rotated each time the electric shaver is used and stored, as in the conventional case. The effort of rotating is saved, which improves usability and prevents the blade portion 2 from being erroneously deformed by fingers.

Although the doglegged groove 13 in this embodiment is formed on the blade mount 7, it may also be formed on the switch lever 26 side and the outward protrusion 31 formed on the support piece 12.

Further, although the switch handle 3 is slidably provided on the razor body 1, it may be provided rotatably.

〔Effect of the invention〕

According to the electric shaver of the present invention, the blade portion is rotated in conjunction with the on and off operations performed by operating the switch handle, so the blade portion is rotated each time the electric shaver is used and stored, unlike the conventional electric shaver. This saves the effort of moving the blade, which improves usability, and prevents the blade from being accidentally deformed by fingers.
