Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an electric shaver that requires a battery.

[Conventional technology]

Conventionally, in battery-powered electric shavers, the switch between the battery and the motor was turned on and off by sliding or pushing the switch opening/closing knob mounted on the outer surface of the main body case. There is. In addition, the battery was replaced by attaching and detaching a battery cover that was removably attached to the battery inlet/outlet at the bottom of the main body case.

[Problem that the invention attempts to solve]

The problem here is that, for example, if you are trying to get a low-cost electric shaver, the above-mentioned conventional ones require you to separately assemble the switch opening/closing knob and the battery slot opening/closing cover. This increases the number of parts and the number of assembly steps, which becomes an obstacle to reducing costs.

Focusing on this point, this invention aims to simplify assembly and structure, reduce costs, and improve usability by incorporating a battery box that has both a lid for opening and closing the battery slot and a knob for opening and closing the switch. The purpose is to

[Means for solving problems]

In order to achieve the above purpose, the present invention
As shown in the figure, a battery box 10 is rotatably incorporated into a main body case 1 having a battery inlet/outlet 11. The battery box 10 includes a terminal plate 20 or 26 that connects the terminals of the battery 8 and the motor 7, an opening 14 that opens the battery slot 11, and a blind wall 15 that closes the battery slot 11. The battery box 10 is located inside the blind wall section 15.
the switch on position, in which the battery inlet/outlet port 11 is closed and the terminal plate 20 or 26 contacts the terminal of the motor 7; The switch is rotatable between the switch-off position and the switch-off position.

[Effect of idea]

According to the present invention as described above, by rotating the battery box 10 at a predetermined angle, the battery is switched off as soon as the battery slot 11 is opened, and the switch is turned on as soon as the battery slot 11 is closed. Since the box 10 is structured to serve both as an opening/closing lid for the battery slot 11 and as a knob for opening/closing the switch, the number of parts and assembly man-hours can be reduced due to its dual functionality, simplifying the structure and assembly, and reducing costs. You can try to bring it down. Moreover, since the switch on/off operation can be performed simultaneously by opening/closing the battery inlet/outlet port 11, it is very easy to use, and is advantageous in meeting the requirements for simple and quick use, especially when traveling.

〔Example〕

Hereinafter, one embodiment of the electric shaver according to the present invention will be described based on the drawings. In the drawings, the main body case 1 is formed into a cylindrical shape, and the upper part of the inside thereof is closed with a hair receiving tray 2, and the bottom part thereof is formed in an open shape. A holder 4 of a mesh-like outer blade 3 is removably screwed into the opening edge of the hair receiving tray 2 of the main body case 1, and a holder 6 having an inner blade 5 inscribed in the outer blade 3 inside the hair receiving tray 2 is rotated. Can be accommodated freely. A motor 7 and a battery box 10 containing AA batteries 8 are housed vertically below the hair receiving tray 2 in the main body case 1. The motor 7 is coupled and fixed to the bottom side of the hair tray 2, and the rotating shaft 9 is connected to the bottom side of the hair tray 2.
The inner cutter holder 6 is supported on the rotating shaft 9, which protrudes upward from the central opening of the inner cutter holder.

In a part of the circumferential surface of the lower half of the main body case 1 that corresponds approximately to the part that accommodates the battery box 10, there is a battery slot 11 having a rectangular shape on the front and having length and width slightly larger than the height and diameter of the battery 8. is opened.

The battery box 10 is formed in a cylindrical shape, and its upper part is closed by a top wall 12 and its lower part is closed by a bottom wall 13, and has an opening 14 corresponding to the battery inlet/outlet 11 and an opening 14 corresponding to the battery inlet/outlet 11 on its circumferential surface. It is formed by arranging blind wall portions 15 that close in the circumferential direction. Further, an outer circumferential wall 16 is provided on the outer periphery of the bottom of the battery box 10 so as to form an upwardly open groove 17 between it and the blind wall portion 15. Furthermore, the battery box 10 is integrally equipped with a cathode terminal plate 20 which connects the cathode terminal 18 which is juxtaposed to the anode terminal 21 and protrudes from the lower end surface of the motor 7 and the cathode terminal 19 of the battery 8.

This battery box 10 is inserted into the main body case 1 from its open bottom, and the bottom open end 1a of the main body case 1 is received in the groove 17. The claws 22 are engaged with engagement holes 23 opened in the circumferential direction of the bottom opening end 1a through elastic deformation of the claws 22 to prevent them from coming off from the main case 1. The anode terminal 21 of the motor 7 and the anode of the battery 8 are located between the anode terminal introduction groove 24 formed in the upper wall 12 of the battery box 10 in the radial direction and the lower end surface of the motor 7 disposed oppositely above the anode terminal introduction groove 24. An anode terminal plate 26 is interposed to connect with the terminal 25.

As shown in FIGS. 3 and 5, the battery box 10 aligns the opening 14 with the battery inlet/outlet 11 to fully open the battery inlet/outlet 11, and connects the movable contact 20a at the upper end of the cathode terminal plate 20 to the motor. 7 and the switch-off position away from the cathode terminal 18 of the motor 7, and as shown in FIGS. 18, and is rotatably assembled between the switch-on position and the switch-on position. At an intermediate position between the fully open position and the fully closed position of the battery inlet/outlet 11, the blind wall 15 allows the battery inlet/outlet 11 to be left in a half-open state and to remain in the switch-off state, as shown in FIG. .

The battery box 10 regulates the fully open and fully closed positions of the battery inlet/outlet 11 by using a position regulating protrusion 27 protruding from the inner circumference of the outer peripheral wall 16 at the bottom of the main body case 1, as shown in FIGS. 8 and 9. This is done by bringing it into contact with a position regulating piece 28 provided at the opening end 1a. FIG. 9 shows the positional relationship between the position regulating protrusion 27 and the position regulating piece 28 when the battery loading/unloading port 11 is half-opened by the battery box 10.
Note that moderation at each position is performed by appropriate means. For example, as shown in FIGS. 5 to 7, a protrusion 29 is provided on a part of the inner circumferential surface of the main body case 1, and a protrusion 29 is provided at an angular position corresponding to the fully open, half-open, and fully closed positions of the outer circumferential surface of the battery box 10. Recesses 30 are provided, and one of the recesses 30 is connected to the battery box 1.
What is necessary is to engage and disengage from the protrusion 29 as the rotation of 0 occurs.

In such a case, the battery 8 can be inserted or removed with the battery box 10 in a state where the battery insertion/extraction port 11 is fully opened. When the battery slot 11 is half-open, the switch is off, and the presence or absence of the battery 8 can be checked and the battery 8 can be prevented from falling out, so it is sufficient to carry the battery in this state. When the battery inlet/outlet port 11 is fully closed, the switch is turned on, and there is no problem such as the hand grasping the main body case 1 touching the battery 8 and accidentally turning off the switch, making it suitable for this use.

In the above embodiment, the anode terminal of the motor 7 and the battery 8 is normally closed, and the cathode terminal is openable and closed.
On the contrary, the cathode terminals may be normally closed, and the anode terminals may be opened and closed depending on the rotation angle of the battery box 10.
