Description

DETAILED DESCRIPTION OF THE INVENTION This invention installs a battery in the toothbrush, and in addition to the normal brushing effect, the structure of the energized toothbrush is improved to the greatest extent possible to more effectively prevent tooth decay and alveolar no-row due to the potential gradient. This was done to simplify, reduce costs, and facilitate widespread use.

Many applications have been filed regarding electronic toothbrushes, but all of them have complex structures and high costs, making it difficult to popularize them. -This invention is patented No. 597157956
．． The present invention relates to improvements in the ionic toothbrushes of Applications No. 59-157940 and No. 59-8-14, which eliminate the above-mentioned conventional drawbacks.

That is, since toothbrushes are used while wet with water, the stored battery is required to have a water-resistant structure.

This invention incorporates a battery in the handle, and an O-ring is installed in a crimped state between the inner surface of the cap, which is fitted onto the handle and serves as a (+) electrode terminal, and the recess in the handle. It is designed to be sealed watertight.

Next, an example of a preferred embodiment of the present invention will be described. The general explanation is omitted since it was given in the original patent application filed on 59-8-14, and the main parts of the present invention will be mainly explained. ■ is a handle, 2 is a support shaft connected to the (-) pole surface of the battery 15 via a spring 16, 3 is a brush head, and a concave end 4 is formed at one end by a groove 6 and an arm 19.19. and is elastically clamped to the convex end 5 of the handle 1. At the tip of the spindle 2, there is a water reservoir 10 in the brush head 3.
and small grooves 8, 8, 8, . . . are formed, and electrical passages are formed between adjacent brush bristles 7, 7, 7, . . . using saliva water or the like as a medium. Reference numeral 13 designates a plurality of mizukiri tsuba whose height gradually increases from the brush side so as not to interfere with the mouth. This is to prevent short circuits due to saliva water, etc. in the grooves 6, 6, etc., which are the exposed parts of 2.

A small hole 17 is formed in the vertical direction of the support shaft 2, and a medium hole 27, a large hole 29, and a shallow groove 28 are formed above the small hole 17. A spring 16 is installed in the small hole 17. In order to double the voltage, batteries 15 and 15 are installed in series in the hollow hole 27. A ring-shaped insulating sheet 31 is placed between the batteries 15. A spiral spring 30 is placed in the center, and the (+) of each battery 15.15
The and (-) pole faces are reliably connected without shorting.

An O-ring 24 is installed in the large hole 29 on the outer periphery of the battery 15, and the O-ring 24 is crimped and fixed by the inner surface of the cap 14, which is elastically clamped and fixed to the handle l, and the bottom surface of the large hole 29. be done. The (+) pole surface of the upper surface of the battery 15 is crimped and bonded to the inner surface of the cap 14 via the spiral spring 30. Therefore, the cap 14 becomes a (+) terminal.

As described above, the minimum space occupied, the minimum number of parts, a very simple structure, ease and efficiency of assembly, reliable water resistance,
The rectangular cross section provides the same ease of use as a regular toothbrush.

4. Additional Relationships This invention is based on the patent application filed on August 14, 1980 (Japanese Patent Application No. 169551/1982), in which the support shaft and the brush portion are connected by a waterway. However, in carrying out the invention of ``Ion Toothbrush'', it is directly necessary to ``invent the handle part and brush part with a built-in battery for use'', which is covered by Patent Law No. 3.
This satisfies the requirements for an additional patent as stipulated in Article 1, Item 1.

Claims (1)

[Claims] 1. A battery is placed inside the handle, and an O-ring is placed in a crimped state between the inner surface of the cap that fits into the handle and the recess in the handle, thereby sealing the battery. An electrified toothbrush. 2. Place an O-ring around the outside of the battery, and make sure that the inside of the cap is O-ring.
The cap fits onto the handle so as to contact the ring and crush the O-ring, sealing the battery, and the (+) pole surface of the battery is in contact with the inner surface of the cap via the spring. Electric toothbrush.
