Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an electric toothbrush machine equipped with an electric toothbrush body that drives a toothbrush by a motor.

[Background technology]

This type of electric toothbrush machine is used by detachably attaching a toothbrush to an electric toothbrush body that incorporates a motor, drive shaft, storage battery, coil, etc., and driving the toothbrush using the electric drive of the electric toothbrush body. ing. By the way, when charging an electric toothbrush, it is charged using a charger installed inside a storage case that stores toothbrushes, etc., but conventional chargers are not integrated into the storage case. It is common for the storage case to be closed and difficult to remove from the storage case, making it unhygienic as the storage case cannot be washed with water.

Furthermore, Japanese Utility Model Publication No. 46-13790 discloses a device in which a charger delivered inside a storage case can be removed from the storage case to charge the charging part inside the electric toothbrush body even outside the storage case. However, in this conventional example, only the charger can be taken out of the storage case, and the relay cord and both ends of the relay cord for electrically connecting the charger and the power cord housed in the charger housing are removed. The plug and socket were integrally formed with the storage case and could not be separated from the storage case. Therefore, this conventional storage case could not be washed with water because there was a risk that water would get into the socket and cause the case to shoot when electricity was applied.

However, with conventional electric toothbrushes, the storage case cannot be washed with water, but toothpaste and dirt attached to the toothbrush tend to stick to the storage case, which poses a hygiene problem. Ta.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned technical background, and its purpose is to make a storage case housing a charger washable with water.

[Disclosure of the invention]

The electric toothbrush machine of the present invention includes an electric toothbrush storage section 8 for storing an electric toothbrush main body 2 in a storage case 5 that is not provided with electrical parts, and a charger 4.
The electric toothbrush housing 8 and the charger housing 6 are communicated through an insertion opening 14 through which the electric toothbrush body 2 is inserted. A charger 4 for charging the charger 3 formed at the bottom is provided with a power supply cord 15, and the charger 4 and the cord 15 are connected to each other.

By taking out the container 4 and the cord 15 from the storage case 5 and making the storage case 5 free of electrical parts, the storage case 5 can be washed with water and the storage case 5 can be kept sanitary.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. As shown in FIG. 1, on the front side of the storage case 5, there is a toothbrush storage section 7 that stores the toothbrush 1 on one side.
On the other side, there is an electric toothbrush storage section 8 that stores the electric toothbrush main body 2 across the front wall 9.
has been formed. The toothbrush storage part 7 is formed with a hook part 12 for hanging and storing the head 11 of the toothbrush 1. In the figure, reference numeral 13 denotes a brush cover that can be opened and closed to cover the toothbrush storage section 7, and is made of transparent acrylic resin or the like. The electric toothbrush storage section 8 is formed slightly above the storage case 5, and an insertion opening 14 into which the electric toothbrush main body 2 is inserted is bored in the lower surface thereof. On the back side of the storage case 5, a charger storage section 6 for storing the charger 4 is formed below the electric toothbrush storage section 8, as shown in FIG. The charger storage section 6 and the electric toothbrush storage section 8 are vertically communicated through an insertion port 14. A cord storage part 16 is formed on the back side of the toothbrush storage part 7 of the storage case 5 to store a power supply cord 15 connected to the charger 4. The cord storage section 16 and the charger storage section 6 are separated by a rear wall 17. The front wall 9 formed between the charger storage section 6 and the toothbrush storage section 7 is formed hollow, and the toothbrush storage section 7 is provided with hot air vents 18. 6 and the toothbrush storage section 7 are communicated through a communication port 10 in the front wall 9. A plurality of hot air vents 18 are formed in the corners of the toothbrush storage part 7 at positions that are located in the head 11 of the toothbrush 1 when the toothbrush 1 is stored in the toothbrush storage part 7. Charger 4
As shown in FIGS. 3 and 6, it is formed into a substantially cylindrical shape, and a primary coil 19 is wound inside it. In the figure, 20 is a yoke, and 21 is an insulator. Inside the electric toothbrush body 2, there is a secondary coil 22,
A storage battery 23, a motor 24, etc. are incorporated, and a drive shaft 25 connected to the motor 24 is made to protrude outward from the head of the electric toothbrush body 2. The toothbrush 1 has its base 26 connected to the drive shaft 25 of the electric toothbrush body 2.
It is designed to be removably attached to and driven. A charging part 3 formed at the lower part of the electric toothbrush main body 2 is housed in the cylinder of the charger 4 so that it can be inserted and taken out. When the electric toothbrush main body 2 is inserted into the cylinder of the charger 4, the current led from the cord 15 flows through the primary coil 19 of the charger 4, and the secondary coil 22 inside the electric toothbrush main body 2 is
A voltage is induced in the storage battery 2 by rectifying this voltage.
3 and charges the storage battery 23.
Reference numeral 27 in FIG. 6 is a back cover, and positioning pins 28, 28 are protruded from the lower part of the back cover 27. , 28 and fit the hook part 30 formed on the upper part of the back cover 27 into the hook stopper part 31 formed on the upper side of the back side of the storage case 5 as shown in FIG. 5 to store the back cover 27. It is designed so that it can be attached to the back of case 5. The hook part 30 is formed of a slightly elastic curved piece, and is configured to form a locking piece 33 on the locked piece 34 of the hook stopper part 31 by pushing down the operating piece 32 that protrudes toward the back cover 27 side. . At the bottom of the back cover 27, a charger holding part 35 is made to protrude toward the storage case 5 side, and can hold and fix the charger 4 stored in the charger storage part 6 in a predetermined position.
