Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating the present invention
Technical solution, and not intended to limit the protection scope of the present invention.
As shown in Figure 1 to Figure 3: present embodiment discloses a kind of electric toothbrushes with pressure monitoring: including inner support 5, line
Road plate 6, support frame 3, inner support 5 are connected to the outside of motor 2, and wiring board 6 is equipped with pressure sensing contact 71, and inner support 5 is equipped with
Conductive material 7, conductive material 7 are connected to pressure sensing contact 71, and motor output shaft 21 is connected to shell 4 by support frame 3.
Specifically, in conjunction with shown in Fig. 3 and Fig. 4: 4 inner wall of shell is set there are two groove 42, and 5 side of inner support is equipped with for connecting
The protrusion 51 of groove 42 is connect, protrusion 51 is connected to groove 42, and the line (chain-dotted line in Fig. 4) of two grooves 42 is perpendicular to brush head
1 direction, in this way protrusion 51 are matched with groove 42, can play the role of fulcrum and axis of rotation.When brush head 1 is connected to horse
When up to output shaft 21, the direction of brush head 1 and pressure sensing contact 71 towards identical or opposite.The direction of the present embodiment brush head 1
Preferably identical with the direction of pressure sensing contact 71, in this way when the pressure of brush head 1 becomes larger, conductive material 7 and pressure are passed
Thoughts and feelings point the distance between 71 is also increased.
In practical set, when inner support 5 is mounted on 4 inside of shell, protrusion 51 can be inserted into along groove 42
The inside of shell 4, groove 42 also acts as the effect of installation guiding at this time.
The support frame 3 of the present embodiment is flexible material, has certain elasticity, when motor output shaft 21 is by radial pressure
When (active force of the tooth for brush head 1 when brushing teeth), support frame 3 can be made to deform, inner support 5 can be made with two in this way
The offset to rotate by a certain angle centered on protrusion 51, and the active force of brush head 1 is bigger, and the offset of generated angle is bigger.
In design, there should be certain gap between inner support 5 and shell 4, which can allow for inner support 5 in shell 4
Do the rotation of certain angle.
The preferred silica gel of the material of this implementation support frame 3, while can also play between sealing shell 4 and motor output shaft 21
The effect in gap avoids intaking in use process.
The quantity of the pressure sensing contact 71 of the present embodiment is no less than two, and all pressure sensing contacts 71 connect
It is connected to conductive material 7.
The present embodiment also discloses a kind of working method with pressure monitoring electric toothbrush, specifically: when user brushes teeth
When, brush head 1 will receive the active force from tooth, and when brush head 1 is under pressure, which acts on support frame 3, make support frame
3 deform, the angle certain as axis rotation using the line of two protrusions 51 of inner support 5, pressure sensing contact 71 and conducting
The distance between material 7 D changes, and when pressure reaches a certain level, the value of D will be more than the preset value L of system, conducting
Material 7 is separated with pressure sensing contact 71 completely, and the pressure sensor circuit in wiring board 6, which receives signal intensity, (generally to be become
High level), then it is judged as that the pressure of brush head 1 is excessive.At this time tooth, gum can be caused to damage if continuing to brush teeth,
System will issue standby signal, and user is prompted to adjust toothbrushing force.
Standby signal includes indicator light flashing, indicator light colors change, vibration motor vibration mode changes (such as vibration frequency
Change, intermittent vibration) or stopping, the acoustical device sending sound or the change sound.
But in some embodiments, the direction of brush head 1 can also be with the direction of pressure sensing contact 71 on the contrary, working as brush head in this way
When 1 pressure becomes larger, the distance between conductive material 7 and pressure sensing contact 71 reduce, and need to only change control system
Internal control logic can be realized, and detailed process no longer illustrates one by one.
The range of preset value L between the present embodiment pressure sensing contact 71 and conductive material 7 is 0.05mm ~ 10mm.
Key 41 due to opening toothbrush is set near pressure sensing contact 71, when operation button 41, is contemplated that
41 pressure of key of influence to to(for) distance between pressure sensing contact 71 and conductive material 7, reasonably adjusts corresponding parameter, example
Such as the triggering pressure of the range of preset value L, the elastic size of support frame 3 and key 41.
The present invention can realize the detection for toothbrushing force size by simple structure, when toothbrushing force is excessive,
User can be reminded, avoids damaging tooth, gum because pressure is excessive.There are many prompting modes of the invention, including
Indicator light flashing, indicator light colors variation, vibration motor vibration mode changes or stops, acoustical device issues the sound or change
The sound.Components for realizing function of the present invention are the mature device of less expensive, lower production costs.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
