Abstract

The present invention relates to a waterproof electronic sound and a light emitting toothbrush, and more particularly, to a toothbrush that can produce a sound and light effect while brushing.

Description

Water-proof electronic sound and light tooth brush

To encourage children to brush, you can use toothbrushes, for example, with cartoon pictures.

However, these toothbrushes with cartoon pictures only have a static appeal. If the toothbrush can have a sound and light effect while brushing, children will love it and like to brush.

2 is a cross-sectional view of the specific embodiment described above;

3 is a cross-sectional view taken along line 3-3 of FIG. 2;

4 is an enlarged view of portion 'A' of FIG. 2;

5 is a circuit block diagram of the sound and light control device of this particular embodiment.

It is a main object of the present invention to provide a waterproof, electronic sound and a luminescent toothbrush that emits sound and light by the user's brushing action.

1 to 4, the present invention includes a handle 1 and a toothbrush head 2.

Handle 1 is a hollow body formed of a light transmissive material and is suitable for accommodating sound and light control device 3. The tail end of the handle is provided with an internal thread 11 which engages the threaded part 42 protruding from the resonance box 4 with a washer 41 for waterproofing.

Resonance box 4 is substantially hollow and includes an outer periphery provided with a through hole 43 for inducing sound and releasing water. Resonance box 4 includes an elastic, waterproof, acoustically permeable membrane 44 secured inward near thread 42.

The sound and light control device 3 includes a contact switch 33 for operating a battery 3 to provide power and a micro CPU 32. The contact switch 33 comprises a metal sleeve 331 with an opening for receiving the opening and the movable metal ball 332, wherein the above-described opening of the metal sleeve 331 faces the metal piece 333 which is not contacted away from the metal sleeve 331. The metal sleeve 331 and the metal piece 333 are respectively connected to the positive electrode terminal and the negative electrode terminal. In addition, the microprocessor 32 is connected to a music IC 34 and a speaker 35. The speaker 35 is installed near the elastic waterproofing acoustically permeable membrane 44. The micro central processing unit 32 is connected to an array of large sized light emitting diodes (LEDs) 36 and small sized light emitting diodes (LEDs) 37. The large sized LEDs 36 are hollowed out between the handle 1 and the toothbrush head 2. It is arranged in the connection 21.

The toothbrush head 2 comprises the above-described connection part 21, the inner circumference of which is formed of a light-transparent curved double rim 211.

5 is a circuit block diagram showing the operation of the present invention. In use, the brushing movement intermittently connects the metal balls 332 of the contact switch 33 to the positive and negative electrode terminals respectively connected to the metal sleeve 331 and the metal piece 333. Therefore, the act of operation follows the brushing action. In addition, the microprocessor 32 is configured to form a closed circuit to maintain an electrical connection for each operation signal for six seconds. On the other hand, the electrical connection can be maintained for longer time intervals to make the operation continuous, or after the operation the electrical connection can be automatically interrupted and stopped. Therefore, the connection switch 33 is operated by brushing operation, and the micro central processing unit 32 is illuminated by the large size LED 36 and the small size LED 37 and the music recorded in the music IC 34 is played through the speaker 35. Is electrically connected to control what is being done. When the brushing operation continuously activates the access switch 33, the LEDs illuminate continuously, the music flows continuously, and consequently can produce special sound and light effects. This effect attracts the attention of the children and makes them more interested in brushing, which eventually maintains the oral hygiene of the children.

Furthermore, referring to FIG. 4, the sound from speaker 35 is resonated in resonance box 4 before exiting through through hole 43. An elastic, waterproof, acoustically permeable membrane 44 is provided between the speaker 35 and the resonance box 4 to emit sound and prevent the ingress of water. A waterproof washer 41 is provided between the resonant box 4 and the tail end of the handle 1 to ensure a more waterproof effect. 2 and 3, the light emitted from the large size LED 36 is conducted and dispersed toward the toothbrush head end by the light transmissive bent double rim 211 formed at the inner circumference of the hollow connection 21 of the toothbrush head. The light emitted from the small size LED 37 shines directly through the handle 1.

As described above, the present invention is interesting for the user to brush by providing a waterproof electronic sound and a light emitting toothbrush that emits sound and light by the user's brushing action, and consequently their oral hygiene. To maintain.
