Abstract

A kind of rotary electric toothbrush includes a brush head, the brush hair on the brush head, a brush rod connected with the brush head; the brush rod is connected with the rotary axis; the rotary axis is driven by the motor and the slowdown element; the motor is provided with a direct-current power supply (the battery or a direct-current transformer of 3V); the direct-current power supply, motor and slowdown element are installed in the shell. The features of the device are: the slowdown element is the small gear driven by the motor; the small gear drives the three-planet gear; the outside of each planet gear is meshed with the tooth ring; the three-planet gear is installed on one end surface of the rotating disc, while the other end surface of the rotating disc is provided with the rotary axis. The electric toothbrush of this technical program is slowed down by the planet gear; the slowdown ratio is large; the rotary axis on the rotating disc is connected with the brush head to rotate continuously after the slowdown; the brush hair cleans the tooth surface and the tooth spacing; the teeth are all cleaned; the effect is good; and the brush head can be replaced.

Description

Rotary electric toothbrush

Technical field

This utility model relates to toothbrush, particularly relates to rotary electric toothbrush, belongs to oral hygiene appliance.

Background technology

The something that must do after people get up every day is to brush teeth to wash one's face, so toothbrush and daily life are very close.The general cleanliness standard of tooth is: the pure white light of dental surface, do not have food waste in the teeth space.The toothbrush that people use now is mostly still with artificial power, cleans that tooth is time-consuming, effort and effect be bad.Usefulness is exactly electric toothbrush in addition, is power by direct current generator generally, moves up and down in the space, can effectively reject the food debris in the teeth space, cleaning teeth.And direct current generator is because rotating speed is very fast, so need to slow down.But to produce up-down vibration, the spacing of vibration is generally 2mm～3mm when work in existing electric toothbrush, and bristle has 8mm long, and the toothbrush after slowing down just can not make the toothbrush vibration as long as compress gently, can not reach the purpose of cleaning teeth.

Summary of the invention

The purpose of this utility model is in order to overcome the shortcoming of prior art, and providing a kind of can scrub continuously to tooth, effectively rejects the rotary electric toothbrush of food debris in the teeth space.

The technical scheme of this utility model rotary electric toothbrush is: a brush is arranged, bristle is arranged on the brush, brush connects brush holder support, brush holder support is connected with turning cylinder, turning cylinder is driven by the motor and speed reducer structure, motor has dc source, dc source, motor and speed reducer structure are installed in the enclosure, it is characterized in that described reducing gear is the pinion that is driven by motor shaft, pinion drives three planetary gears, each planetary gear is outer to be meshed with gear ring, and three planetary gears are installed on the end face of rotation disc, and turning cylinder is installed in the other end of rotation disc.The electric toothbrush of the technical program is to be slowed down by planetary gear, and speed reducing ratio is big, and the turning cylinder on the rotation disc after the deceleration connects head toothbrushes and rotates continuously, and bristle is cleaned with water dental surface and teeth space, and tooth is brushed totally, and is effective, and brush can be changed at any time.Motor can connect two-direction switch control, and it is more reasonable that the upper and lower jaw of tooth is brushed teeth.

Rotary electric toothbrush of the present utility model, its described bristle are to be distributed on the circumference of brush, uniform can brushing teeth continuously around the bristle.Its bristle that is distributed on the brush circumference is four row or six rows.The dc source of its motor is aneroid battery or 3V commutator transformer (on sale on aneroid battery or the 3V commutator transformer market).Its planetary reduction gear is one group or two groups of series connection decelerations, and two groups of series connection are slowed down and can further be reduced rotating speed, alleviate the wearing and tearing of tooth.

Fig. 2 is this utility model rotary electric toothbrush planetary gear speed reducing mechanism sketch map;

Fig. 3 is that this utility model rotary electric toothbrush bristle is installed in sketch map on the brush circumference.

The specific embodiment

The utility model discloses a kind of rotary electric toothbrush, as shown in Figure 1, a brush 1 is arranged, bristle 2 is arranged on the brush, brush connects brush holder support 3, brush 1 can be made into one with brush holder support 3, brush holder support is connected with turning cylinder 5, can there be shaft joint or plug-in connection 4 etc. in the centre, turning cylinder 5 is driven by motor 9 and reducing gear, motor 9 has dc source to link to each other, so be direct current generator, motor has on and off switch 6, two-direction switch 7 can also be arranged, dc source, the motor and speed reducer structure is installed in the shell 11, and shell 11 can be used as the brush holder of shaking hands, and shell arrives head, but the shell of head is half slit bamboo or chopped wood only, one side of something exposes bristle in addition, and its major technology is characterised in that described reducing gear (as shown in Figure 2) is the pinion 16 that is driven by motor shaft, and pinion can be installed on the motor shaft, pinion 16 drives three

planetary gears

13,14,15, each planetary gear is outer to be meshed with gear ring 12, and therefore, reducing gear is a planetary gear speed reducing mechanism 8, three

planetary gears

13,14,15 are installed on the end face of a rotation disc 17, turning cylinder 5 is installed in the other end of rotation disc 17, and from turning cylinder 5 outputs, turning cylinder drives brush 1 to motor 9 behind planetary gear speed reducing mechanism 8 during work.Its described bristle 2 is to be distributed on the circumference of brush, as shown in Figure 3, and uniform bristle around the brush.Its bristle 2 that is distributed on the brush circumference is four rows' (as shown in Figure 3) or six rows.The dc source of its motor 9 is aneroid battery 10 or 3V commutator transformer.On sale on aneroid battery and the 3V commutator transformer market, it is more laborsaving to use aneroid battery, but power consumption is fast, and expense is big; Using the 3V commutator transformer can charge on the 220V alternating current power supply.Its planetary reduction gear is one group or two groups of series connection decelerations, and one group as shown in Figure 2, and two groups of decelerations add one group again, and it is the same that each organizes structure.
