The positional relationship is such that when one terminal and the other terminal are in contact and the power to the drive motor is turned on, and when the head is not bent, one terminal and the other terminal are in a non-contact state. , covering the connecting portion between the razor body and the head with a cylindrical and bellows-shaped expandable waterproof member;
It is characterized in that both ends of the waterproof member are connected to the razor body and head, respectively, to form a waterproof structure.

(effect) Next, we will discuss the effect.

By bending the head of the electric razor,
When one terminal and the other terminal come into contact, power to the drive motor is turned on, allowing shaving. Also, since it has a waterproof structure, it can be used in bathrooms, etc.

(Embodiments) Hereinafter, preferred embodiments of this invention will be described in detail based on the accompanying drawings.

The general reference numeral 10 indicates an electric shaver. Figure 1,
As shown in FIG. 2, this electric shaver 10 is
Main body 14 housing battery 30 and inner blade unit 2
4, a bendable head 12 consisting of an outer cutter 26 and a drive motor 22.

In the head 12, a horizontal partition 18a is formed on a cylinder 18 constituting the head 12, and this partition 18a
A drive motor 22 is clamped and fixed by a support plate 20 screwed to the partition wall 18a. Further, a drive shaft 22a protrudes from a through hole in the center of the partition wall 18a and is connected to the inner cutter unit 24. An outer cutter 26 is detachably provided on the upper part of the cylinder 18.

The main body 14 is also formed in a cylindrical shape, and the battery storage section 2
6 is constituted by a partition wall 28 and a cap 15 provided at the lower end of the main body 14.

Next, the state of engagement between the head 12 and the main body 14 will be explained.

Two first and second guide plates 28a and 28b protrude in parallel from approximately the center of the partition wall 28 of the main body 14. (A state in which the first guide plate 28a is removed from FIG. 1 is shown in FIG. 2). First guide plate 28
A V-shaped through hole 29 is bored in a. In the gap between the first guide plate 28a and the second guide plate 28b, there are two
It is sandwiched between two arc-shaped guide pieces 32a, 32b and the guide pieces 32a, 32b, and has gaps 36a, 36.
A piece 35 having a shape b is located in a protruding manner. The two guide pieces 32a, 32b are provided in a substantially V-shape, and arcuate guide holes 33a, 33b are bored in the center portions of the guide pieces 32a, 32b. When the head 12 of the electric shaver 10 is not bent (see FIG. 2 in the normal state), pins 34a and 34b are attached to the upper ends of the guide holes 33a and 33b.
the first and second guide plates 28 so that
Pins 34a and 34b are fixed to a and 28b. Further, a plurality of recesses 33c are formed in each of the guide holes 33a and 33b. Further, the guide holes 32a, 32b are formed such that the center lines of the guide holes 33a, 33b are arcuate about the centers O, O of the pins 34a, 34b.

A protrusion 35a protrudes from the tip of the piece 35 and engages with the through hole 29 of the first guide plate 28a.

Therefore, when the head 12 is bent in the direction A, the head 12 tilts around the pin 34a,
The guide hole 33b of the guide piece 32b is guided by the pin 34b and is inclined, while the through hole 2 of the first guide plate 28a
The protrusion 34a is also guided by the left side portion of the through hole 9b (29a is the left side portion of the through hole and 29b is the right side portion of the through hole). Further, since the gap 36b is formed between the guide piece 32b and the piece 34, the guide piece 32b causes a slight elastic change in the left and right direction, and the pin 34b is moved into the guide hole 34.
It can be supported by the appropriate recess 33c of 3b (the same applies when the head 12 is bent in the direction B). Note that the first guide plate 28 between the piece 35 and the protrusion 35a
The engagement of a with the through hole 29 is not necessarily necessary.

Next, the switch structure will be explained.

A through hole 28c is provided in the center of the partition wall 28 of the battery storage portion 26 of the main body 14, and an L
A conductive plate 38 is provided as a terminal for the letter-shaped switch (see FIG. 3). And conductive plate 3
A through hole 38a is formed in the center of the upright portion 38a of the electric shaver 10, and a switch pin 40 as a terminal for a switch connected to the drive motor 22 is inserted through the through hole 38a of the conductive plate 38 when the electric shaver 10 is in a normal state. It is located in the hole 38b and maintains the off state. In addition,
The upright portion 38a of the conductive plate 38 is connected to the second guide plate 2.
It is attached to 8b. Therefore, when the switch pin 40 is located at the position of the through hole 38b of the conductive plate 38, the switch pin 40
8b, and is in a non-contact state with the conductive plate 38. The through hole 38b of the conductive plate 38 is made a non-current-carrying part (see FIG. 4). On the other hand, the negative terminal of the battery 30 is connected to the spring 4 on the top surface of the cap 15.
2. It is connected to the drive motor 22 via conductive plates 43, 44 and a cord 45.

Therefore, when the head 12 is bent in the A direction as described above, the switch pin 40 comes off from the light-transmitting part 38b of the conductive plate 38, and the upright part 3 of the conductive plate 38
8a and turns on.

On the other hand, a connecting portion between the head 12 and the main body 14 is covered with a waterproof member 46. This waterproof member 46 is
It is made of rubber and has a cylindrical and bellows shape.
Then, the upper edge of the waterproof member 46 is connected to the drive motor 2.
2 and the support plate 20, and the other end is held between the main body 14 and the support plate 20.
The grip part 48 is connected to a grip part 48 that wraps around the outer circumference of the main body 14, and has an uneven surface and a lower end fixed to the lower end of the main body 14.
Furthermore, since the drive shaft 22a of the drive motor 22 has a waterproof structure, such as having a transparent hole sealed with a sealing member 50, it can be used in a bath or the like. In addition, the space 5 at the lower end of the inner cutter unit 24
A hole 18c may be formed in a part of the space 52 to remove water from the space 52.

In addition, in the above embodiment, the guide pieces 32a, 3
Although two guide pieces 2b are provided, for example, one guide piece 32a
Alternatively, the pin 34a may be rotatably fixed to the head 12 so that the head 12 can be bent only in the A direction. Further, the guide pieces 32a and 32b may be provided in a V-shape instead of a V-shape. Furthermore, the same effect can be obtained even if the engagement relationship between the head 12 and the main body 14 is reversed.

(Effects of the invention) As explained above, by bending the head relative to the razor body, the terminal for one switch comes into contact with the terminal for the other switch, and the power to the drive motor is turned on. This makes it possible to shave. In this way, by linking the switch structure and the bending of the head, a razor body that is easy to hold can be realized without providing a separate switch.

In addition, it has a waterproof structure in which the connecting part between the head and the main body is covered with a waterproof material, so it can be used in baths and other places with great effect.
