Abstract

The utility model relates to a toothbrush with music, which is provided with a sound set circuit in a toothbrush handle. The sound set circuit is composed of a switch, a music integrated chip, a loud-speaker and an electrical power supply. When people begin to brush teeth, the switch is connected and the toothbrush begins to play music. When the teeth brushing ends, the music stops. The toothbrush with music is particularly suitable for children to use and can raise interests of the children to brush teeth, and help the children to form a habit of liking brushing teeth. Adults use the toothbrush with music can also get pleasure.

Description

Toothbrush with music

The utility model relates to electronic toy or toilet article field.

Domestic once had a toothbrush foundation that can send musical sound, and toothbrush one is taken away, and switch is just connected, and is played music by miniature radio cassette player.Do not see the musical toothbrush that has sound system and toothbrush to make one.

The purpose of this utility model provides a kind of sound system and toothbrush all-in-one-piece musical toothbrush.

Accompanying drawing 1(a) being the essential structure schematic diagram of the utility model musical toothbrush, (b) is its acoustics circuit figure.

This musical toothbrush is made up of head toothbrushes 1 and toothbrush handles 2, make hollow container 10 in the toothbrush handles 2, the built-in acoustics circuit of forming by switch 3, music integrated chip 4, loudspeaker 5 and power supply 6 at least (b), one utmost point of described power supply 6 links to each other with the external power supply end of music integrated chip 4 corresponding polarity by switch 3, another utmost point of power supply 6 links to each other with another external power supply end of music integrated chip 4, one end of loudspeaker 5 links to each other with the output of music integrated chip 4, and the other end links to each other with the positive pole of power supply 6; Have the vocal hole 8 that seals with waterproof membrane 9 stickups with surface, loudspeaker 4 corresponding position on the toothbrush handles 2, hollow container 10 adopts waterproof sealings.

The switch 3 of above-mentioned acoustics circuit (b) can adopt hand switch, often opens push switch as be provided with one corresponding to the position of holding on toothbrush handles 2, and the Shi Shouyi that brushes teeth holds toothbrush handles 2, just switch 3 is connected.Switch 3 also can adopt the on-off circuit that is made of sensing element 14 and at least one transistor 11.Sensing element 14 places the toothbrush surface and brushes teeth the closely-related position of behavior.The information that sensing element 14 is experienced when brushing teeth is converted into switching signal, amplifies, connects acoustics circuit through triode 11 and make it to play music.Described sensing element 14 can be dew cell, temperature-sensitive element or pressure cell, and they are respectively can change adhesional wetting, variations in temperature or pressure to provide change in electric, thus the element of gauge tap circuit.

For ease of changing battery, hollow container 10 can be provided with waterproof sealing lid 7, and combination can be clamping, be threaded or the screw-nut connection.Can adopt packing ring or paste waterproof membrane and prevent the water-soaked circuit; For guaranteeing that acoustics circuit does not make moist, porose or position, the slit outer surface of toothbrush handles 2 also can add cover one integral waterproofing film in addition.

Head toothbrushes 1 can be done monoblock type or split type with toothbrush handles 2.Adopt split type benefit to be, can more renew head toothbrushes at any time, and the toothbrush handles 2 that acoustics circuit is housed can be used repeatedly when the 1 usefulness old times of head toothbrushes.

The utility model musical toothbrush is simple in structure, compact.When beginning to brush teeth, switch 3 is connected, and acoustics circuit is played music; The end of brushing teeth, switch 3 cuts out, and music stops.The utility model musical toothbrush especially is fit to children to be used, and attracts their interest to brushing teeth, and is convenient to the parent education children from cultivating good health habits for a short time.The adult uses, and also can increase delight of life.

Fig. 2 (a ') is the structural representation of a kind of specific embodiment of this musical toothbrush, and Fig. 2 (b ') is that it implements circuit diagram, and Fig. 2 (c ') is head toothbrushes 1 and toothbrush handles 2 bond sites cross-sectional views.

In the present embodiment, head toothbrushes 1 adopts buckle to link with toothbrush handles 2.Switch 3 adopts the switching signal circuit of being made up of dew cell 14 and triode 11.Dew cell 14 be two groups of fine copper wires parallel to each other or copper sheet, every group have one at least, each other at a distance of 2mm, inlay and be fixed in that for example available electric iron hot pressure of position outer surface near head toothbrushes 1 is embedded on the surface mutually on the toothbrush handles 2.Loudspeaker 5 adopts piezoelectric ceramic piece.Power supply 6 adopts two button cells of series connection mutually.The base stage of described triode 11 links to each other with the positive pole of power supply 6 by dew cell 14, and emitter stage links to each other with the negative pole of power supply 6, and colelctor electrode links to each other with the external power supply negative pole of music integrated chip 4; The external power supply positive pole of music integrated chip 4 links to each other with the positive pole of power supply 6; The two ends of piezoelectric ceramic piece 5 link to each other with the positive pole of power supply 6 and the output of musical film 4 respectively.But filling foamed plastics also can be installed in relevant electronic component on one substrate and be fixed in the hollow container to fix each element relative position in the toothbrush handles 2.Lid 7 is tightly connected with toothbrush handles 2 by screw 12 and pad 13.Have the aperture 8 of several φ 2mm on the toothbrush handles 2 corresponding to the sounding position of piezoelectric ceramic piece 5, liner waterproof membrane 9 is in order to avoid infiltration.Toothbrush total length 16cm, hollow container 10 inside dimensions are 4.5cm * 0.8cm * 0.6cm(length * wide * height), the toothbrush handles profile can be made cross section for circular, oblate or rectangular rectangular.

In this enforcement, triode is selected 3DG6 for use, and musical film is selected KD152 for use; During installation, musical film is convenient to install to reduce volume keeping cutting under the prerequisite of its function as far as possible for a short time; Piezoelectric ceramic piece is selected φ 20mm for use, also is cut into the rectangular of wide 8mm.The music of musical film can be selected as required.During batch process, musical film and piezoelectric ceramic piece can customize.

When beginning to brush teeth, the conducting because dew cell 14 gets wet, triode 11 conductings, music integrated chip 4 obtains the power supply supply and sends music signal, sends music by piezoelectric ceramic piece 5.Brushing teeth finishes, and wipes water stain on the dried dew cell 14 or with its drying, musical sound stops.
