Description

[Detailed Description of the Invention] The present invention relates to an electric shaver, and its first object is to provide a 4-inch electric shaver that is convenient to carry. The purpose of this invention is to provide an electric shaver that is easy to use.The third objective is to provide an electric shaver that prevents the lid from being lost.

Conventional electric razors are held in a main body case that houses a blade body consisting of an outer blade body and an inner blade body, a drive unit that drives the inner blade body of the blade body, and a heat source that supplies electricity to the drive unit. The blade is protected by a removable lid, and if the grip is small, it will be difficult to use, so it is possible to make the electric shaver more compact by making the main body case extremely small. This caused the problem that electric razors became large.

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 invention. In FIGS. 1 to 4, a main body case 1 is made of a synthetic resin molded product, and is composed of an upper case 2 and a lower case 3, and houses a motor 4, which is a driving section. 5
are ball support arms with arcuate tips, which are formed by extending both side walls of the main case 1 to face each other, and form a U-shape with the end surface 6 of the main case 1.

It consists of a push-up spring (not shown) that pushes up the
It is connected to the output terminal 10 of the motor 4.

Reference numeral 11 denotes a dome-shaped outer cutter body, which is composed of an outer cutter 12 in which a large number of whisker introduction holes (not shown) are drilled, and an outer cutter base 13 for attaching the outer cutter 12 to the main body case 1. The inner blade 7 is slidably in contact with the inner surface of the blade.

Reference numeral 14 denotes a blade body, which is composed of an outer blade body 11 and an inner blade body 7.

Reference numeral 15 denotes a lid body formed to have substantially the same outline and thickness as the main body case 1, and the lid body 15 has a blade housing recess 16 at a position corresponding to the blade body 14, and a step on a side wall 17 for hooking a finger. Part 18
A pivot arm 20 having an arcuate tip is formed extending from both sides of the end face 19, and a mirror body 21 is adhered to the bottom face of the storage recess 16.

22 is a parts box in which a battery 23 as a power source is stored;
It is closed from the lid 241.

Reference numeral 25 denotes a shaft portion formed on opposing surfaces of each bag support arm 5, and a concave support portion 2 formed on both side walls of the parts box 22.
6. It is supported by a wisteria support that can be rotated freely.

Reference numeral 27 denotes a click member that allows the main body case 1 and the parts box 22 to click, and includes a projection 28 provided on the opposing surface of each pivot arm 5 and a terminal board 29 provided on both side walls of the parts box 22. The holes 30 with which the protrusions 28 engage are formed in eight 45 locations on the terminal plate 29.

Reference numeral 31 denotes a base portion formed on the opposing surface of each key support arm 20, and a position on both side walls of the parts box 22 where the distance 1 between the locks and the core support portion 26 is equal to the thickness of the main case 1 or the lid body 15. The sardine is rotatably supported on a concave shaft support 32 formed in the .

The parts box 22 is formed to have a dimension parallel to the line connecting the shaft supports 26 and 32 (longitudinal dimension) twice as thick as the main body case 1, and a dimension perpendicular to the line connecting the shaft supports 26 and 32 (longitudinal dimension). ) is formed to have the same thickness as the main body case 1. 33
is a click member that clicks between the lid 15 and the parts box 22, and includes projections 3 formed on the opposing surfaces of the respective koji support arms 28, and 8 projections distributed 45o on both side walls of the parts box 22. It is composed of holes 35 formed in places,
The nuclear protrusion 34 is engaged with the hole 35 . 36 is a contact spring, which protrudes from the main body case 1 and is disposed within the support arm 5 along the support arm 5, and is in contact with the terminal plate 29;
It is connected to the motor 4.

Reference numeral 37 denotes a battery contact fitting A arranged in the parts box 22, and is provided with a coil spring 38 and a protrusion 39 so that both the positive terminal and the negative terminal of the battery 23 can be energized.

40' is a battery contact metal fitting B disposed inside the parts box 22, and has a protrusion 41 so that it can conduct electricity with the positive terminal of the battery 23.
is formed and is electrically connected to one terminal board 29.

Reference numeral 42 designates an electrical contact metal fitting C disposed within the parts box 22, which is provided with a coil spring 43 so as to be able to conduct electricity with the negative terminal of the battery 23, and is electrically connected to the other terminal board 29.

44 is a switch pin of the main switch, which protrudes from the side wall of the power supply box 22 via a spring (not shown).

The switch pin 44 is pressed by the support arm 201 of the lid 15 when the lid 15 is closed against the main body case, and turns off, and when the lid 15 is opened against the main body case 1, the switch pin 44 is turned off. Turns on. 45 is a brush body for cleaning the blade body, which is stored in the parts box 22.

Next, the state of use will be explained with reference to FIGS. 5 to 9.

FIG. 5 is a perspective view showing the state of the main body case and the lid body when the blade body 14 of the main body case 1 is not used for shaving. The main body case 1 and the lid body 15 are attached to the end portion 6 of 1.
The parts box 22 is installed without protruding from the top. 6th
The figure shows main case 1 when used as a shaver.
2 is a perspective view showing the state of the lid body 15, and when the lid body 15 is opened with respect to the main body case 1 by hooking a finger on the step portion 18 for finger hooking, the main switch is turned on and the motor 4 rotates. This causes the inner blade body 7 to rotate and become ready for use. The main body case 1 is angled with respect to the parts box 22 and the lid 15, so that the lid 15 and the main body case 1 can be grasped by hand during use. FIG. 7 is a perspective view showing the state of the main body case 1 and the lid 15 in another usage method. The entire device can be held in the hand and used. FIG. 8 and FIG. 9 are diagrams showing the state of display. In the example, the case where the main body case and the lid body were supported on the parts box at different locations was explained, but the main body case and the lid body were supported on the parts box at the same location. However, the lid can be used as a grip.

In this way, when the main body case 1 and the lid body 15 have substantially the same outline, the side wall of the main body case 1 and the side wall of the lid body 15 are approximately flush with each other, so that the lid body 15 and the main body case 1 can be easily separated by hand. When held in the hand, it does not feel uncomfortable in the hand and has the effect of being easy to grip.
The longitudinal dimension of the parts box 22, which separately supports the ends of the main body case 1 and the lid body 15, which are formed to have the same thickness, is formed to be twice the thickness of the main body case 1, and the width direction dimension is The one having the same dimensions and thickness as the main body case 1 has the effect that there is no gap between the main body case 1 and the lid 15, resulting in an excellent appearance. The click part 33 is provided between the main body case 1 and the parts box 22, and between the parts box 22 and the lid body 15. This has the effect that the main body case wing and the lid body turtle 5 can be positioned, making it easy to use.

The electric shaver according to the present invention includes a main body case provided with a blade body, a bottomed lid body with one end closed corresponding to the blade body, and disposed between the main body case and the lid body. The main body case and the lid body are rotatably supported on the parts box, so that it is easy to use an electric shaver. If not used, the lid that protects the blade can be overlapped with the main case, and the overall length is halved, resulting in a smaller size.When using an electric razor, the lid can be used as a grip. This has the effect that it is easy to use even if the main body case is small, and there is also the effect that the lid body cannot be lost.
