Abstract

The utility model relates to a pneumatic toothbrush. The utility model adopts the technical proposal of a pneumatic toothbrush comprising a brush head, a brush body and a motor unit, the motor unit is positioned in the brush body and comprises a motor, a battery and a switch. The utility model is characterized in that a guiding gear, a guiding bar and a gas piston are positioned in the brush body, wherein the guiding gear is connected with the motor and the both ends of the guiding bar are connected with the guiding gear and gas piston respectively. A gasbag and a gas transmission tube are arranged in the brush head, and the gasbag is connected with the gas transmission tube as a whole, bristle is positioned on one end of the brush head, the bristle is connected with the gasbag closely, so is the gasbag and the brush head, the transmission tube and the gas piston, the brush head and the brush body action. The pneumatic toothbrush has a compact size and has no harm to the gum, which fits the right way to brush and makes the teeth much cleaner.

Description

Pneumatic toothbrush

Technical field:

This utility model relates to a kind of toothbrush, particularly a kind of electronic air operated pneumatic toothbrush that is converted to.

Background technology:

At present, toothbrush on the market mainly contains two kinds of plain edition and power types.Though the power type toothbrush is easy to use, also have many shortcomings: brush is thicker, uses and has sense of discomfort; Brush is formed by a lot of unit constructions, and can there be the slit in this compound mode, uses just to have many toothpaste after a period of time and dirt remains in the slit, and easily breed bacteria is extremely unhygienic; Electric toothbrush not only movement velocity is fast, and its bristle is that its motion mode has been violated our correct method for brushing teeth, not only very easily hurts gingiva, but also can take dirt in the teeth crevice in rotation.

Summary of the invention:

In order to address the above problem, this utility model provides that a kind of volume is little, Anti-dental injury gum, the pneumatic more completely toothbrush of cleaning.The technical solution adopted in the utility model is: a kind of pneumatic toothbrush, comprise brush, brush body, motor drive mechanism, motor drive mechanism is installed in the brush body, motor drive mechanism is made up of motor, battery and switch, it is characterized in that guide gear, guide post and gas piston are arranged in the brush body, guide gear is connected with motor, and the two ends of guide post connect guide gear and gas piston respectively; Air bag and gas delivery tube are arranged in the brush, and air bag and gas control delivery are integral, and an end of brush has bristle, and bristle is connected with air bag is airtight, and air bag is connected with brush is airtight, and gas delivery tube is connected with gas piston, and brush and brush body flexibly connect.

Described bristle is software rubber bristles or software rubber bristles and conventional bristles mixed type two kinds.

Brush and brush body are detachable, as required replaceable brush head.Brush and brush body socket connection.

Operation principle is: the motion of driven by motor guide gear, and by guide post gas piston is seesawed, thereby make air expansion and the contraction in the air bag in the brush, drive outside, the inwardly motion of bristle.

The beneficial effects of the utility model are: because air bag and gas delivery tube adopt software rubber to make one, volume is little, is installed in the brush, and head thickness is reduced, and is the same with the brush of ordinary toothbrush, and brush can not feel well in use like this.Bristle and air bag are combined closely, and air bag is connected with the brush housing is airtight, can not form the slit on brush, prevent that toothpaste and dirt from remaining in the slit, guaranteed the hygienic requirements of toothbrush.This utility model has adopted the air operated principle of electronic conversion, because a hollow gasbag is arranged in brush, driven by motor guide gear motion in the brush body, guide post drives the gas piston generation and seesaws, thereby make in the brush air expansion in the hollow gasbag drive bristle and do inside and outside motion with shrinking, act on the tooth, move up and down exactly, this motion mode meets our correct method for brushing teeth, and because employing is pneumatic, movement velocity is moderate, can not hurt gingiva, more can make bristle go deep into teeth crevice, clean more thoroughly, use hommization more and rationalization.

The specific embodiment:

Embodiment 1

Shown in Fig. 1～4, a kind of pneumatic toothbrush, comprise brush 1, brush body 2, motor drive mechanism, motor drive mechanism is installed in the brush body 2, motor drive mechanism is made up of motor 3, battery 4 and switch 5, and motor 3 is connected with battery 4, and the circuit of switch 5 is arranged between motor 3 and the battery 4, being connected of motor, battery and switch adopted conventional the connection, and switch 5 is installed on the hull outside of brush body 2.

Guide gear 6, guide post 7 and gas piston 8 are arranged in the brush body 2, and guide gear 6 is connected with motor 3, and the two ends of guide post 7 connect guide gear 6 and gas piston 8 respectively; Air bag 10 and gas delivery tube 9 are arranged in the brush 1, and air bag 10 and gas delivery tube 9 are made one, and an end of brush 1 has bristle, bristle and 10 airtight connections of air bag, and

air bag

10 and 1 airtight connection of brush, gas delivery tube 9 is connected with gas piston 8.

Bristle adopts software rubber bristles 11.

As Fig. 3 and shown in Figure 6, when driving guide gear 6, motor 3 moves, and guide post 7 drives gas piston 8 forward and travels forward, Compressed Gas, air expansion in the air bag 10, bristle outwards moves.As Fig. 5 and shown in Figure 7, guide post 7 drives gas piston 8 backward and moves backward, air shrinkage in the air bag 10, and bristle inwardly moves.

Embodiment 2

Shown in Fig. 8～9, a kind of pneumatic toothbrush, it is that software rubber bristles 11 and inside are conventional bristles 12 mixed types that bristle in the brush 1 adopts the outside, other structure is with embodiment 1, because the outside is a software rubber bristles 11, in use, can not hurt gingiva, and the inner conventional bristles 12 of using, because conventional bristles has certain rigidity, the dirt in more can the cleaning teeth slit.
