Abstract

The utility model relates to a multifunction electric toothbrush, which is provided with a bidirectional rotary brush head of a tooth percussing head and a tooth head of a message head. Besides, the toothbrush also overcomes a defect that the rotary direction of the brush bristles of a previous electric toothbrush is inconsistent with the sanitary requirement of tooth brushing. The utility model not only has multifunction of tooth brushing, tooth percussing, massage, health, etc., but also has the advantages of easy fabrication and safe and convenient use.

Description

Multifunction electric toothbrush

At present, had electric toothbrush on the market, still, some deficiency of this electric toothbrush.The one, function singleness, function only cleans the teeth; The 2nd, the direction of rotation of bristle is inconsistent with the hygienic requirements of brushing teeth.This electric toothbrush brush then is a direction brush along tooth for rotation (square with the axis) hygienic requirements of brushing teeth radially.Xuan Zhuan bristle radially exerts oneself to be difficult for cleaning the teeth when light, when firmly heavy, and easy damaged gums often.

The purpose of this utility model is that the above-mentioned weakness to existing electric toothbrush makes improvements: 1. the brush of a bi-directional axial rotation of design (direction of rotating with axle is consistent).Make the rotation direction of bristle consistent with the hygienic requirements of brushing teeth.2. design a clicking the teeth head, to increase the function of teeth consolidating, strong tooth.3. design a gum-massaging head, to strengthen the function of prevention Gum disease.

The purpose of this utility model is achieved in that 1. on the basis that keeps existing electric toothbrush motor and critical piece (handle), changes a two-way switch, makes motor can do forward and reverse moving; 2. design the brush of a two-way rotation bristle, bristle is fixed on the brush head axis by pulvinus, and brush docks in the socket mode with main frame (handle); 3. design a clicking the teeth head, this brush is hammered into shape by tooth, tooth hammer cover, bent axle, bent axle cover, and axle holder and bristle bar are formed.The tooth hammer is hollow structure, and the sweep of bent axle is enclosed within the hollow of tooth hammer, and when connecting switch, the tooth hammer moves both vertically under the effect of bent axle, kowtows and hits the tooth occlusal surface; 4. design a gum-massaging brush, this brush is made up of massage cushion, spring, sheath, flat axle, axle holder and brush holder support.Massage cushion is a solid construction, and in sheath, the flat of axle partly is pressed on the massage cushion by latch bracket, and when the energized switch, massage cushion trembles under the effect of flat axle, plays stimulation, massage effect.

This utility model is compared with existing electric toothbrush, has the following advantages: increased clicking the teeth, the health care massage function; Changed the direction of rotation of former electric toothbrush bristle, made the rotation direction of bristle conform to the tooth hygiene requirement, make simply, safe in utilization, convenient.

Figure 14 is each brush head axis of this utility model and boss rod johning knot composition.

Referring to Fig. 1,2,3, as seen from the figure, sheath of the brush of the bristle of two-way transfer bristle (1) and axle sleeve (3) are one-piece type, bristle sheath (1) front is one fan-shaped, protects 1/2 of bristle (2).The axle (5) of bristle (2) is through the axocoel of sheath (3), and the cone oblique crank Z holder (6) on nose circle cone tank and the sheath (1) offsets, and axle (5) fixes with bristle pad (4), and bristle (2) fasciculation is planted in the pore (9) of bristle pad (4).

Referring to Fig. 4,5, as seen from the figure, this head is by tooth hammer (12), tooth hammer cover (10), axle sleeve (11) and bent axle (13) composition.Tooth hammer cover (10) is hollow (a 16) cylindrical shape, and is integral with axle sleeve (11), and tooth hammer (12) is positioned at the hollow (16) of hammer cover (10); And become closely to cooperate; Bent axle (13) is positioned at the axocoel (14) of axle sleeve (11).

Referring to Fig. 6,7, tooth hammer (12) is a hollow cylindrical, and the diameter of tooth hammer (12) is slightly less than the internal diameter of hammer cover (10), and the height of tooth hammer (12) is greater than the thickness of hammer cover (10).Tooth hammer (12) hollow is made up of two parts, the minor face that axle asks (15) face to open rectangular opening (17) is slightly larger than the diameter of axle (13), the rectangle projection (21) that long limit, hole (17) is slightly larger than bent axle (13) adds axle sleeve (11) face bent axle (13) diameter and hammer (12) into shape at tooth, open oblate hole (18), the degree of depth in hole (18) equals 3/4 of tooth hammer (12) diameter, hole (18), about (horizontal stroke) footpath equal tooth hammer (12) diameter and projection (21) highly, the vertical footpath in flat hole (18) equals the long limit of rectangular opening (17), the vertical footpath in flat hole (18) equals the long limit of rectangular opening (17), and the last lower wall (19) of flat hole (18) is more flat.

Referring to Fig. 8, crankshaft front end is a cone-shaped groove (20), and there is a rectangle projection (21) front portion of axle (13), and cone-shaped groove (20) offsets with axle holder (15), and rectangle projection (21) is positioned at the flat hole (18) of tooth hammer (12).
