Abstract

The utility model discloses an Electric rotating toothbrush which adopts an electric machine as dynamic force. Electricity is supplied for the electric machine by a battery, and the on-off of the electric machine is controlled by a switch. The transmission of dynamic force of the gear wheel of the electric machine, an inner gear wheel, a connecting rod, an angle gear wheel, a duplex gear wheel and the gear wheel of brush bristle leads the brush bristle to be vertical to a brush handle (a tooth surface) to rotate. The rotating directions of the adjacent brush bristle are opposite. The brush bristle can be thoroughly spread, which can thoroughly remove residual food at the depth of a tooth slot. A tooth root can not be damaged. A tooth bed can be massaged. The blood circulation of the periodontium can be promoted. The utility model can keep teeth healthy. The plug-in structures for the brush head and the brush handle lead the brush head and the brush handle to be conveniently disassembled, assembled, cleaned and replaced. One brush handle can be used by a plurality of people. The toothbrush is a late-model high-grade health care toothbrush.

Description

Electric rotating toothbrush

This utility model relates to daily life tools, particularly rotary electric toothbrush.

The toothbrush that uses in the daily life is made up of bristle and brush holder, and bristle is fixed on an end of brush holder, and this toothbrush people with low cost, easy to use always get used to horizontal brush.Along with the raising of human society for the understanding of importance of dental care, science proves that horizontal brush can't remove the residue in the teeth space, goes down just to cause the formation of various odontopathies for a long time, and it is understandable that China has 80% people to suffer from various odontopathies.In order to address this problem, the someone proposes a kind of rotary electric toothbrush that rotates along teeth space, be that bristle changes around brush holder, this toothbrush thoroughly changes the bad habit of horizontal brush, can remove the residue in the teeth space, but when the bristle of toothbrush turns to the root of the tooth position, to damage root of the tooth unavoidably, simultaneously must install guard shield additional in the one side of colliding with epipharynx, otherwise injure epipharynx, the residue of putting off until some time later the teeth space depths still can't thoroughly clean.Say that more all-in-one-piece brush brush holder structure can't be utilized brush holder again and caused waste.

The purpose of this utility model be to overcome the deficiencies in the prior art and provide a kind of bristle can vertical brush holder be that the vertical flank of tooth rotates, can thoroughly remove the rotary electric toothbrush that teeth space depths residue and brush interchangeable are pegged graft.

The purpose of this utility model is achieved by the following scheme: the motor of aneroid battery, switch keying is housed in the chamber of being made up of brush holder, brush and back shroud, is fixing the drive mechanism of motor gear and transferring power on the motor output shaft; Cover plate and many bristle is housed on the brush, and drive mechanism makes bristle obtain the power of rotation, and brush and brush holder are dismountable socket connections.Drive mechanism comprises the internal gear with the motor gear engagement, it is fixed with one with the connecting rod that is bearing on the brush, the other end of connecting rod is being fixed bevel gear, it and duplicate gear mesh, duplicate gear is while and bristle gears engaged again, and adjacent bristle gear intermeshes again and carries out transmission of power, on each bristle gear bristle is housed all, the vertical brush holder rotation of bristle, just vertical teeth space (being the vertical flank of tooth) rotation.

This rotary electric toothbrush is compared with known technology, fundamentally changed the bad habit of the long-term horizontal brushes of people, because simultaneously vertical teeth space (flank of tooth) rotation of plurality of bristles and adjacent bristle switched in opposite, so bristle can fully be unfolded, thoroughly remove the residue at each position, teeth space depths, not only the Anti-dental injury root also is simultaneously the massage stimulation to dental bed, promote the blood circulation of periodontal tissue effectively, reach the function of dental care.The brush of plug-in type, brush holder structure, dismantled and assembled cleaning, replacing only can be used for many people with a brush holder, change the outfit and go up difform brush member, can be for different people in difference

The following use.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

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

Describe in further detail by above-mentioned accompanying drawing embodiment.

The socket connection mutually of the brush holder (12) of rotary electric toothbrush (referring to Fig. 1-2) and brush (4), brush holder (12) tail end is pressed into back shroud (13), 1 joint 1.5V aneroid battery (11) and motor (9) is housed in their chamber, switch (14) is equipped with in the outside, the three is electrically connected with the metallic conduction sheet, motor (9) is fixed on brush holder (12) inner chamber by interior cover (8) and inner casing cover (10), interior cover (8) and inner casing cover (10) and brush holder (12) inner chamber close-fitting have played the water proof and dust proof effect to motor (9), battery (11).

Fixing motor gear (15) on motor (9) output shaft, internal gear (7) engagement in it and the brush (4), this internal gear (7) is bearing on the projecting shaft of interior cover (8), two pins are arranged, can peg graft with connector (6), connector (6) and metal connecting rod (3) pressure injection one, connecting rod (3) is bearing in the brush (4) by fixed block (5) again simultaneously, a bevel gear (2) is fixed in its upper end, bevel gear (2) and duplicate gear (16) engaged transmission, make Rotation With Changing to, duplicate gear (16) is parallel with two row centrages simultaneously again, adjacent two engagements in 10 bristle gears (1) that centre-to-centre spacing equates, power just is delivered to each bristle gear (1), the switched in opposite of adjacent two bristle gears one by one.Bristle (17) is bonded in bristle gear (1) center, and is pressed into brush (4) by cover plate (18) and makes the interior root of Dahurian angelica of bristle gear (1) in chamber and bristle (17) exposes.

During use, the position that switch (14) is placed out, motor (9) starts, drive drive mechanism by motor gear (15), through bevel-gear sett (2), (16) commutation, drive bristle gear (1) and rotate, make bristle (17) do rotatablely moving of vertical brush holder (12), finish the function of cleaning teeth.
