Abstract

The utility model relates to a daily service dental apparatus, a brush head is composed of brush hairs, a roll centre, a brush shaft, a waterproof seal, a support bracket and a joint. A body is composed of a contact head, a reversing switch, a brake switch, a body case, a speed limiter, a commutator, a speeding up gearset, a spring group, etc. The brush head is connected with the body into a whole through a screw (a joint to fit the contact head). The brush hairs have no gingiva injury when brushes downward along tooth gaps. Compared with an ordinary dental apparatus, the utility model is sanitary and comfortable, and the utility model which uses no electricity is cheaper and safer than an electric toothbrush. The utility model which is portable can be used at any where, one machine has a plurality of heads, and the utility model can be used by all family members.

Description

Toothbrush with spiral power spring

This utility model belongs to daily toilet article:

Existing ordinary toothbrush, not as the electric toothbrush health, and electric toothbrush is dangerous.Be subjected to the electricity restriction, price and expense height.

The purpose of this utility model is: along interdental brush, and tissues such as Anti-dental injury gum, health, not electricity consumption, safety, every household are available everywhere.

The scheme that this utility model is taked is: press the lower tail switch, the clockwork spring group is housed in the shell, afterbody is equipped with the clockwork spring lid, by clockwork spring power transmission shaft and winder, to the clockwork spring group energetically, accelerator and diverter that the clockwork spring group is formed by clockwork spring power transmission shaft driven gear, select to turn to by reversing switch, pass to brush, make the brush rotary work by limiter of speed, axle, contact head, by reversing switch and brake switch, transposing turns to and stops arbitrarily.

This utility model has 5 width of cloth figure:

Fig. 1 and Fig. 2 form the longitudinal sectional drawing of this utility model concrete structure

Fig. 3 is the profile of this utility model along the A-A line

Fig. 4 is the profile of this utility model along B-B

Fig. 5 is the profile of this utility model along C-C

Below engaging accompanying drawing is further described this utility model:

Accompanying drawing 1 explanation: bristle (1) is fixed on (2) one weeks of roll centre, and roll centre (2) is fixed on the axle (4), and axle (4) is by water proof ring (3), and support (6) and joint join.

Accompanying drawing 2 explanations: casing is equipped with the clockwork spring group in (8), and casing (8) afterbody is equipped with clockwork spring lid (7), and (see figure 4) is pressed brake switch (31) and rotated the clockwork spring lid.Give clockwork spring (10) and clockwork spring (11) energetically by clockwork spring turning cylinder (9).When clockwork spring (11) is full, parallel card (12) just pushed down gear (13), because of gear (13) and clockwork spring (10) are fixed on the same winder (14), so clockwork spring clockwork springs (11) such as (10) has been had an effect, be pressed onto parallel card (12) lower end, when stretching the little tooth in clockwork spring (11), just can have an effect, (see figure 4) is opened brake switch (31), clockwork spring power transmission shaft (9) driven gear (15); Gear (16) is enclosed within on the axle (17), separate with lubricating pad between gear, form accelerator, accelerator drives diverter (see figure 3) and limiter of speed, pouring weight (18) is gone up at minor axis (19) and is slided, and hauled by spring (20), when speed is high, pouring weight (18) just with the dead turn friction, thereby limit the brush rotating speed by contact (22) and joint (5).Annotate: parallel card (12) one ends two between cog have certain distance.

Accompanying drawing 3 explanations: this figure is a diverter, carrier wheel (23), intersect respectively gear (24) and (25), but move wheel all the time not from gear (16), pressing reversing switch (26) moves wheel (23) and leaves gear (25) and coincide along the tooth of gear (16) and the tooth of gear (24), at this moment the brush direction is just changed commentaries on classics, returns original position when letting go, external rubber (28) envelope waterproof.

Accompanying drawing 4 explanations: press brake switch (31) when going up bar, spring leaf (29) is pressed on the bundle tooth (30) all the time, the casing (8) in the time of can making energetically is nonreversible.May command clockwork spring power transmission shaft (9) in the work, thus the whole brush of control rotates, and brake switch (31) external rubber (28) is shut.

Accompanying drawing 5 explanation: this figure is the basic block diagram of clockwork spring (10) and clockwork spring (11), and two winders are character for this reason all, and clockwork spring is buckled in casing (8) outward, in be buckled on the winder.Winder (14) internal tooth and clockwork spring power transmission shaft (9), unidirectional the interlocking of external tooth (32) allows a clockwork spring static like this.

Claims

1, this utility model verticlly-brushing type clockwork spring toothbrush, this brush is by reversing switch and brake switch, brush (Fig. 1) and body (Fig. 2) are formed, and it is characterized in that: bristle (1), the anti-water seal (3) of roll centre (2), axle (4), joint (5), support (6) etc. constitute brush, are made up of casing (8), contact (22), reversing switch (27), brake switch (31), limiter of speed, accelerator, accelerating gear group (16), clockwork spring group etc.Brush (Fig. 1) is dressed up an integral body by screw [joint (5) and contact (22) are coincide] and body (Fig. 2).

2, by the described bundle tooth of claim 1 brake switch, its feature: form by carrier wheel (23), gear (24), gear (25), spring (26), switch (27), rubber envelope (28).

3, by the described bundle tooth of claim 1 brake switch, its feature: rubber envelope (28), switch (31), shell fragment (29), bundle tooth (30) are formed.
