Abstract

The utility model relates to a toothbrush which can automatically feed water for flushing when a user brushes teeth. The toothbrush of the utility model is composed of a toothbrush body, a pump and a water tank. The toothbrush body comprises a brush handle, a direct current motor, a gear wheel on the shaft rod of the motor, a brush bristle seat and a bearing. The brush bristle seat is a rotor, the front end surface is provided with brush bristle, and the back end surface is provided with a rotating shaft is pivoted with the bearing. The outer periphery of the back end surface is provided with a tooth array which drives with the gear wheel in an engaging mode. The rotating shaft is provided with through holes which penetrate through the brush bristle seat. A water channel is arranged in the brush handle. One end of the water channel is positioned at the center of an inner step trough at the front of the brush handle, and the other end of the water channel is electrically connected with the pump. The motor rotates, which drives the brush bristle seat to rotate. After the pump is started, water liquid is ejected from the water channel, and water can be automatically fed when a user brushes teeth.

Description

Tooth-brush with automatic water supply

This utility model relates to a kind of toothbrush, but relates to a kind of toothbrush of self water feeding flushing when brushing teeth or rather.

The gear of eccentric shaft is established in existing electric toothbrush mostly with a direct current driven by motor one top, the rotation of dependence eccentric shaft drives puts reciprocally oscillating motion about the sleeve work, again by this socket joint toothbrush body, make toothbrush according to the left and right sides, axle center reciprocally swinging, the electric toothbrush of this kind structure has the shortcoming of following three aspects:

1, the eccentric shaft by gear and top thereof drives toothbrush body indirectly and makes left and right sides reciprocally swinging, complex structure not only, and its relative moment will reduce by pressurized when brushing teeth exponentially, promptly can influence driving force under the state of normally brushing teeth, and suitable transmission effect can not be arranged.

Pressurized was fragile when 2, drive mechanism was than complexity and because of use.

3, there are not waterworks.

Tooth-brush with automatic water supply of the present utility model comprises brush holder, is arranged on the direct current generator in the brush holder and is fixed on the gear on the motor axostylus axostyle and be positioned at the hair brush base of brush holder one end, it is characterized in that:

Comprise that also a water tank and is linked in the pump between water tank and tooth-brush handle;

Be provided with the two rank groove that is made of interior rank and outer rank in the described tooth-brush handle top, be installed with a bearing in the interior rank, described gear is positioned at outer rank; Described hair brush base is a rotor, described bristle plants on the rotor front end face, described hair brush base rear end periphery is provided with the denture with meshed transmission gear, and described hair brush base rear end face is provided with the rotating shaft that is coupling with bearing, and rotating shaft central authorities are provided with the through hole that runs through hair brush base; Also be provided with water channel in the described tooth-brush handle, water channel one end is positioned at described rank central authorities, and the water channel other end and pump connect.

Also be provided with the control valve of regulating discharge between described water tank and pump.

Direct current generator drives the hair brush base rotor rotation, and behind the power supply of primer pump, water sprays from water channel, provides flushing water when brushing teeth.

Further specify technology of the present utility model below in conjunction with the embodiment accompanying drawing

Fig. 1, Tooth-brush with automatic water supply structural representation

Fig. 2, Fig. 1 toothbrush main body structure sketch map

Referring to Fig. 1, Tooth-brush with automatic water supply is made of toothbrush body 1, pump 2 and water tank 3, and water tank 3 is used to store water liquid, connects with pump 2, establishes control valve 31 therebetween and is used to regulate discharge.Pump 2 is used for the output of pressurized water liquid, and an end and water tank 3 connect and be water inlet end, and the water channel 15 of the other end and toothbrush body 1 connects, and is the water side.

Referring to Fig. 2 and in conjunction with referring to Fig. 1, the handle portion top of toothbrush body 1 offers two rank groove 11 forward, two rank groove is divided into outer rank 111 and interior rank 112 in regular turn, be respectively applied for a ccontaining hair brush base rotor 13 and bearing 12, be provided with motor in the body 1, the top of motor axostylus axostyle 14 sets firmly an external gear 141, its working gear face is positioned at outer rank 111, make the rotor revolution with 13 engagements of hair brush base rotor, these rotor 13 front ends are stretched and are provided with rotating shaft 133, rotating shaft 133 central authorities then establish through hole 134, and rotor 13 is coupling with bearing 12 and places in the outer rank 111.Be provided with water channel (or water pipe) 15 in the body 1, this water channel 15-end is positioned at the central position on rank 112, and the other end then connects with pump 2.

Starter makes axostylus axostyle 14 vertical external gear 141 rotations, meshes the denture 132 of hair brush base rotor 13 simultaneously, and rotor 13 is rotated according to bearing 12 centers.Whether establish change-over switch on the brush holder of toothbrush body 1 of the present utility model, whether the startup of control pump (be) is used for selecting feeding water.When switching to synchronous feedwater towards Xian, the pump action makes water liquid by two rank groove 11 central authorities and rotor ejection relatively, is flowed out by through hole 134, can be in the feedwater flushing simultaneously of brushing teeth.

The characteristics of this utility model Tooth-brush with automatic water supply are:

1, with motor external gear integral drive hair brush base rotor rotation, the integral drive effect is arranged, relative moment can not fall sharply exponentially in the pressurized action when brushing teeth.

2, drive mechanism is simple, can increase service life, reduce manufacturing cost.

3, waterworks are set, more meet the actual requirement of brushing teeth.

This utility model is by improving the toothbrush body structure and pump being set and water tank is realized goal of the invention.Establish conduit and be communicated with pump in body, the external gear engagement hair brush base rotor denture by the motor axostylus axostyle makes the rotor revolution, can select flushing water in electric tooth brushing.

Claims

1, a kind of Tooth-brush with automatic water supply comprises brush holder, is arranged on the direct current generator in the brush holder and is fixed on the gear on the motor axostylus axostyle and be positioned at the hair brush base of brush holder one end, it is characterized in that:

2, Tooth-brush with automatic water supply according to claim 1 is characterized in that: also be provided with the control valve of regulating discharge between described water tank and pump.
