Abstract

The utility model relates to a frequency-convertible electric toothbrush. The frequency-convertible electric toothbrush comprises a toothbrush handle, a toothbrush head, a battery, a driving motor and a controller. A pressure sensor for sensing a pressure of the toothbrush head is arranged on the bottom of a bristle base plate of the toothbrush head; the pressure sensor is used for outputting a corresponding changable current according to a contact pressure of the toothbrush head and teeth; the controller is used for controlling the rotating speed of the driving motor according to the change of the output current so as to adjust the change frequency of the toothbrush head; the bristle base plate of the toothbrush head is movably connected with the toothbrush head so that a toothbrush base plate can be replaced.

Description

A kind of frequency conversion electric toothbrush

Technical field

This utility model belongs to the toothbrush application field, relates in particular to a kind of frequency conversion electric toothbrush.

Background technology

Existing electric toothbrush frequency and dynamics are unified, but for the different users, not necessarily applicable, especially for the child, can't grasp suitable method for the moment during due to use, easily damage tender gingiva, make gingiva the symptoms such as red and swollen occur, also can make simultaneously tooth meet with violent wearing and tearing, severe patient also can cause periodontitis, causes loss of tooth; In addition for the electric toothbrush that increases frequency modulation function, be by the switch switch and manually transfer gear, very inconvenience when the child is used.Therefore how to make electric toothbrush can adapt to the demand of different crowd, being one is worth the problem solved.

Summary of the invention

This utility model can change the dynamics of toothbrush vibrations in time in order to solve electric toothbrush, so that the actual demand of cleaning oral cavity when adapting to user and brushing teeth provides a kind of frequency conversion electric toothbrush, comprises handle, head toothbrushes, battery, drive motors, controller.The bristle base plate bottom of head toothbrushes has the pressure transducer of sensing head toothbrushes pressure, pressure transducer is according to the electric current of head toothbrushes with the corresponding variation of contact pressure output of tooth, controller is controlled the rotating speed of drive motors according to the variation of output current, regulate the head toothbrushes frequency of vibration.

Further technological improvement of the present utility model is, the bristle substrate of frequency conversion electric toothbrush is movable the connection with head toothbrushes, the replacing toothbrush substrate.The healthy use in the toothbrush situation, needed three months to change a toothbrush, but the cost compare of electric toothbrush is high, and every three months is changed a toothbrush, and cost is too expensive, by the bristle substrate design of electric toothbrush, is therefore removable, saves use cost.

Further technological improvement of the present utility model is, the handle of frequency conversion electric toothbrush has skid resistant course, and skid resistant course is the textured rubber sleeve of tool.Because electric toothbrush is different from ordinary toothbrush, in use obvious vibrations can occur, in order to prevent unexpected toothbrush, come off, on handle, be provided with skid resistant course.

This utility model is obtained following technique effect:

This utility model is by the technological improvement that the common electric toothbrush is carried out, and cost increases not obvious, can, so that user can change electric toothbrush vibrations dynamics by tooth and toothbrush contact pressure according to own oral hygiene situation, clean; Also make the child use, avoid, because common electric toothbrush frequency dynamics can't change, causing the red swelling of gingiva phenomenon.

The accompanying drawing explanation

Fig. 1 is the schematic diagram of this utility model frequency conversion electric toothbrush.

The specific embodiment

For the ease of those of ordinary skills, understand and implement this utility model, below in conjunction with the drawings and the specific embodiments, this utility model being described in further detail.

Embodiment:

This utility model has been announced a kind of schematic diagram of frequency conversion electric toothbrush, and Fig. 1 is frequency conversion electric toothbrush schematic diagram, comprises handle 1, head toothbrushes 2, battery 3, drive motors 4, controller 5.The whole material of handle is plastics, and the outer wrap rubber layer, have striped on rubber layer, play anti-skidding effect.Bristle substrate 6 bottoms of head toothbrushes 2 have the pressure transducer 7 of sensing head toothbrushes pressure, pressure transducer 7 is according to the electric current of head toothbrushes with the corresponding variation of contact pressure output of tooth, controller 5 is controlled the rotating speed of drive motors 4 according to the variation of output current, regulate head toothbrushes 2 frequency of vibration.Bristle substrate 6 is movable connection the, replacing toothbrush substrate 6 with head toothbrushes 1.Handle has skid resistant course, and skid resistant course is the textured rubber sleeve of tool.Toothbrush total length 140 millimeter, 22 millimeters of head length, 9 millimeters of brush width, bristle adopts the flexible plastic fiber, while brushing teeth, the suitableeest power is 3N, pressure transducer 7 is selected silicon piezoresistance type pressure sensor, this transducer range is 0-80Mpa, between its input voltage and output voltage, exist good linear relationship, drive motors is that DC micromotor just can be satisfied the demand, during use, from hands, just picked up toothbrush a moment, because the head toothbrushes 2 of frequency conversion electric toothbrush does not touch tooth, do not produce pressure, the silicon piezoresistance type pressure sensor output voltage is zero, DC micromotor is not moved, head toothbrushes 2 frequency of vibration are zero, when the head toothbrushes 2 of frequency conversion electric toothbrush tentatively touches tooth, head toothbrushes 2 produces pressure with tooth, by silicon piezoresistance type pressure sensor, sense pressure signal, be converted into voltage signal and be transferred to controller 5, controller 5 is controlled the rotating speed of DC micromotor according to the linear change of output voltage, control head toothbrushes 2 frequency of vibration, as long as just can control the frequency of DC micromotor to the contact pressure between control head toothbrushes 2 and tooth, reach the purpose of thorough cleaning teeth, toothbrush is head toothbrushes 2 and the disappearance of tooth contact pressure after using, the automatic stop motion of DC micromotor, at this moment will thoroughly wash down toothbrush with clear water, dries the water liquid on bristle, then toothbrush upwards is placed on the cradle of toilet and charges, in ventilation, dry up simultaneously.

Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For this utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
