Description

[Detailed description of the invention] 【Technical field】

The present invention relates to a rechargeable electric shaver using a storage battery as a power source. r − + p e] The conventionally available rechargeable electric razors are as follows:
It is roughly divided into species. In other words, there are two types: those that are charged by connecting directly to a commercial AC power source or via a power cord, and those that are charged by being connected to a nine-car battery connected to a commercial AC power source via a charging adapter. be. By the way, from the user's point of view, it is preferable that the power supply has high versatility so that it can be charged both at home and in the car, and from this point of view, the latter type of the above two types is preferable. The one is good. This is because it can be configured to be directly connected to a car battery for charging, and connected to a commercial AC power source via a charging adapter for charging. However, in this case, when charging from a commercial AC power source, a dedicated charging adapter must be prepared, and when used on the go, the photoelectric adapter must also be carried.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned α, and its purpose is to be able to perform charging from both a commercial AC power source and a DC power source, and to eliminate the need for a separate charging device. There is no need to offer a rechargeable electric razor.

[Disclosure of the invention]

However, the present invention has two types of power supply, one for commercial AC power supply and one for DC power supply.
It is characterized by being equipped with two charging terminals, a storage battery that is charged by input from both charging terminals, and a blade drive motor that operates as the main battery power source. The battery is equipped with dedicated charging terminals for both a commercial AC power source and a DC source, and these charging terminals are connected to each power source so that charging can be performed from either power source. It is. The present invention will be described in detail below based on the illustrated embodiments.
The figures to FIG. 6 show one embodiment, and the main body 1 has a built-in motor 2 for driving a blade and an M battery 3, and a plug 40 that protrudes from the side and is inserted into a cigarette lighter socket of a car. is provided as a charging terminal 4 for a DC power source, and furthermore, a shiny 5o is provided on the back side as a charging terminal 5 for a commercial AC power source to which a power cord plug 51 as shown in FIG. As shown in Figure t56, the charging circuit 6 includes a DC charging circuit 61 that performs voltage step-down and an AC charging circuit 62 that performs rectification and voltage step-down. This device can be charged by inserting the plug 40 into a car's cigarette lighter socket, and can also be charged from a commercial AC power source via the power cord plug 51. To ensure that you can always charge from both types of power sources,
The power cord plug 51 must also be carried and stored, but compared to a charging adapter, it is not a problem to carry, and even if you lose it, you can easily replace it. products can be obtained. Of course, instead of the jack 50, a plug blade that can be inserted into a commercial power outlet may be provided, and in this case, the power cord plug 51 becomes unnecessary. Other embodiments are shown in FIGS. 7 to 14. This is main body 1
A charging terminal 4 for a DC power supply and a charging terminal 5 for a commercial AC power supply are both arranged on the back of the power supply, and a power supply hood plug 42 having a plug 40 at one end to be inserted into a cigarette lighter socket is connected. jack 45
is the charging terminal 4, and the mower blades 55, 55, which can be raised and lowered, are the charging terminal 5.
The plug cover 13 is configured to be divided into two parts, and a plug cover 13 is attached to the back side. As shown in Figure Pt512, this plug cover 13 can be slid freely by engaging claws 14 on both side edges with grooves 15 provided in the housing 12, and has a protrusion 16 on the inner surface. We are prepared. The plug blades 55, 55 are integrally connected by a molded product 56 and are rotatable about the molded product 56 as an axis. .17 and slide the plug cover 13 upward in the figure.
Due to the engagement between the protrusion 16 and the engaging portion 57 of the molded product 56, the plug blades 55, 55 rotate and close the plug cover 13.
It protrudes backward through the contact metal JAc 58 and is connected to the charging circuit 6 by contacting the contact metal JAc 58 . The jack 45 consists of a pin 46 and a contact spring 47, both of which protrude from the board of the charging circuit 6! As shown in FIG. 1314, the plug portion 41 of the power supply hood plug 42 has an anode terminal portion 43 on the inner surface and a cathode terminal portion 44 on the outer surface.
When inserted, the bottle 46 contacts the anode terminal 43 and the contact spring 47 contacts the cathode terminal 44, as shown in FIG. 21 in the figure is a switch handle, 22 in FIG. cathode metal fitting that contacts the cathode terminal of
24 is driven by the switch handle 21 and the cathode metal fitting 23
A switch terminal 25 in contact with the switch terminal 25 is a connecting fitting that is connected to the switch terminal 24 and to the cathode of the storage battery 3 via the charging circuit 6. Other embodiments are shown in FIG. 115 and FIG. 16. The basic configuration is the same as the above embodiment, but the charging terminal 4 for DC power supply
The arrangement of the gloss 45 is different. That is,
In the above embodiment, the plug blades 55, 55 which are the charging terminals 5
The charging terminal 4 was placed below the plug, but here a shuck 45 is placed between the two plug blades 55°55. In the embodiment shown above, the charging terminal 4 for DC power supply and the charging terminal 5 for commercial AC power supply are arranged together on the back of main body 1, making it small and easy to grip (and when viewed from the front) The shape of the blade was designed to be compact, but by arranging the glossy blade 45 on the side of the double blade 55, it was possible to save space and make it even more compact. [Effect] As described above, since the present invention includes a charging terminal for a commercial AC power source and a charging terminal for a DC power source, charging from both types of power sources is possible without the need for a separate charging adapter. It is highly versatile with respect to power sources, so it can be charged anywhere, making it easy to use.
