Abstract

The utility model provides a spiral-bristle double-column electric toothbrush for brushing teeth, which is characterized in that brush bristles on two brush columns on a brush head are in spiral arrangement, one accords to right-handed arrangement, and the other one accords to left-handed arrangement. When teeth are brushed, the brush bristles in spiral arrangement continuously brush teeth in fistfuls under the transmission of a gear; single fistful of brush bristles is easier to brush the depth of tooth gaps, and corresponding fistfuls of brush bristles on the two brush columns are arranged in 90 DEG. When each fistful of brush bristles brushes teeth, the brush bristles on the two brush columns do not influence each other so that each tooth gap of teeth can be brushed.

Description

The electric toothbrush of spiral bristle twin columns

The present invention relates to a kind of improved electric toothbrush, particularly a kind of spiral bristle twin columns electric toothbrush that bristle is independent of each other.Be suitable for scrubbing tooth.

Toothbrush or electric toothbrush that the existing apparatus of brushing teeth is general, bristle all is several rows of arrangement on the brush, the apparatus of selling on the market of brushing teeth is exactly that this form is arranged.Because tooth structure makes teeth space and facing not in one plane and toothbrush bristle is arranged and to be formed a plane, when scrubbing tooth, when touching tooth, one row brush hair will be blocked by high position, want to brush the teeth space depths, just must push a row brush hair with certain power, make the bristles bend that touches the high position of tooth, the part bristle is brushed in the teeth space.Bristle arrangements is many more, is difficult for scrubbing the teeth space depths more.The power on the crooked bristle of being pressed will produce gingiva and stimulate the injury gingiva.So often tooth can not be scrubbed clean, damage gingiva again.

Task of the present invention is that the electric toothbrush of a kind of improved spiral bristle twin columns will be provided, and it can scrub the teeth space depths easily, and bristle is independent of each other again.

Task of the present invention is finished as follows; Being used to scrub on the brush of tooth has one of two bristle above the brush post to adopt dextrorotation to arrange, and one is adopted left-handed arrangement, and their are with being contained in the semicircle sheath.Under the transmission of gear, face toward rotation with same speed.When scrubbing tooth, be that the pugil pugil is scrubbed tooth when bristle touches tooth like this, if when scrubbing tooth, bristle touches facing, just the high position of tooth.Single pinch of bristle is easy to bending, scrubs along gingiva because of bristle again, and the power that gingiva is produced is very little.Descend the pugil bristle just can directly scrub the teeth space depths like this.Because corresponding every pinch of bristle becomes 90 ° of placements on two brush posts, when pugil contact tooth was scrubbed, corresponding pugil bristle did not reach tooth.Along with two brush posts synchronously rotate, scrub the bristle roll brush mistake of tooth, the bristle that does not brush tooth turns over scrubs tooth.During roll brush toothwash tooth, the bristle on not only single brush post is independent of each other such two brush posts under gear drive, and bristle also is independent of each other between the two brush posts.More become in each position of scrubbing tooth, reach the purpose of cleaning teeth.

Below in conjunction with accompanying drawing invention is described in further detail.

Fig. 1 is the longitudinal sectional drawing of a kind of concrete structure of the present invention.

Fig. 2 is the partial side view of Fig. 1.

Fig. 3 is the gear rotation cutaway view of Fig. 2 along the A-A line.

Be arranged in dextrorotation, left-handed respectively with reference to the bristle on Fig. 1, Fig. 2, Fig. 3 spiral brush sifter post (1) and the spiral brush sifter post (2).Gear (4), gear (5) and spiral brush sifter post (1), (2) cast one, in the sheath 29 of packing into, every pinch of corresponding bristle becomes 90 °, tumbler gear (6) and gear (5) interlock, tumbler gear (7) respectively and gear (6), gear (4) interlock and are contained in axillare (28).Transmitting gear (8) is fixed on the power transmission shaft on (10), and and tumbler gear (7) interlock.Power transmission shaft (10) is fixed together by cavity in the brush (11) and reduction gearing (13), and two is separately fixed on fixed cover (27) and the location-plate (14), reduction gearing (13) and be fixed on motor (15) and go up motor gear (12) interlock.Sealing ring (9) is contained in the ante-chamber of brush (11), is used to seal water.Motor (15) is contained in the forward cavity of brush handle (16), and the positive pole (17) of positive electricity level (18) and motor (15) is connected, and the negative pole (24) of negative electrode (23) and motor (15) is connected.Switch (26) is contained in outside brush handle (16) front opening, and electrode slice (25) is bonding or be connected in the brush handle (16).Battery (19) is contained in brush handle (16) back cavity, and the sharp bonnet in brush handle (16) rear end (20) is with being threaded, and electrode slice (22) is fixed on the bonnet (20) with screw (21).

When pull switch (26), electrode (25) and negative electrode (23) are connected, motor (15) rotates, motor gear (12) transmission reduction gearing (13), give travelling gear (8) by power transmission shaft (10) transmission, travelling gear (8) transmission tumbler gear (7), tumbler gear (7) is distinguished transmission again and is given travelling gear (6) and gear (4), tumbler gear (6) travelling gear (5), spiral brush sifter post (1) and spiral brush sifter post (2) are in gear (4), in the generation of gear (5), is down moving, faces toward rotation with different directions respectively, and spiral brush sifter post (1) (2) is though facing to rotation, rotate at the same space again, because adopt the structure of spiral bristle, bristle can not twine all the time, brush (11), brush handle (16), bonnet (20).Switch (26) can be made of plastic.Gear can be made with nylon or metal material.
