Detailed Description
The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1 to 3: the embodiment discloses an electric toothbrush with pressure monitoring: the motor output shaft connecting structure comprises an inner support 5, a circuit board 6 and a support frame 3, wherein the inner support 5 is connected to the outer side of a motor 2, the circuit board 6 is provided with a pressure sensing contact 71, the inner support 5 is provided with a conducting material 7, the conducting material 7 is connected to the pressure sensing contact 71, and a motor output shaft 21 is connected to a shell 4 through the support frame 3.
Specifically, with reference to fig. 3 and 4: the inner wall of the shell 4 is provided with two grooves 42, the side part of the inner support 5 is provided with a bulge 51 used for connecting the grooves 42, the bulge 51 is connected with the grooves 42, the connecting line (the chain line in figure 4) of the two grooves 42 is vertical to the orientation of the brush head 1, so that the bulge 51 is matched with the grooves 42 and can play the roles of a fulcrum and a rotating shaft center. When the brushhead 1 is connected to the motor output shaft 21, the brushhead 1 is oriented in the same or opposite direction as the pressure sensing contacts 71. The orientation of the brush head 1 and the pressure sensing contact 71 of this embodiment are preferably the same so that as the pressure of the brush head 1 increases, the distance between the conductive material 7 and the pressure sensing contact 71 also increases.
In actual assembly, when the inner bracket 5 is installed inside the outer shell 4, the protrusion 51 can be inserted into the inner shell 4 along the groove 42, and the groove 42 also serves as an installation guide.
The supporting frame 3 of this embodiment is made of a soft material and has a certain elasticity, so that when the motor output shaft 21 is radially pressed (by the force of the teeth on the brush head 1 during brushing), the supporting frame 3 can be deformed, so that the inner frame 5 can be rotated by a certain angle around the two protrusions 51, and the larger the force of the brush head 1 is, the larger the angular deviation is. In design, the inner support 5 and the outer shell 4 should have a certain clearance, which allows a certain angular rotation of the inner support 5 within the outer shell 4.
Silica gel is preferably selected to this implementation support frame 3's material, can also play the effect in clearance between seal housing 4 and the motor output shaft 21 simultaneously, avoids taking place into water in the use.
The number of the pressure sensing contacts 71 of the present embodiment is not less than two, and all the pressure sensing contacts 71 are connected to the conductive material 7.
The embodiment also discloses a working method of the electric toothbrush with the pressure monitoring function, which specifically comprises the following steps: when a user brushes teeth, the brush head 1 can be acted by the acting force from teeth, when the brush head 1 is stressed, the pressure acts on the support frame 3 to deform the support frame 3, the inner support frame 5 rotates for a certain angle by taking a connecting line of the two bulges 51 as an axis, the distance D between the pressure sensing contact 71 and the conducting material 7 changes, when the pressure reaches a certain degree, the value of D exceeds the preset value L of the system, the conducting material 7 is completely separated from the pressure sensing contact 71, and a pressure sensing circuit in the circuit board 6 receives the signal change (generally becomes high level), so that the pressure of the brush head 1 is judged to be overlarge. At this time, if the tooth brushing is continued, the teeth and the gum are damaged,
the system will send out prompt signal to prompt the user to adjust the brushing pressure.
The prompting signal comprises flashing of an indicator light, color change of the indicator light, change or stop of vibration mode of a vibration motor (such as vibration frequency change and intermittent vibration), sounding of an acoustic device or change of sound.
However, in some embodiments, the orientation of the brush head 1 may be opposite to the orientation of the pressure sensing contact 71, so that when the pressure of the brush head 1 becomes higher, the distance between the conducting material 7 and the pressure sensing contact 71 is reduced, and the process can be implemented only by changing the control logic inside the control system, and the specific process is not described one by one.
The range of the preset value L between the pressure sensing contact 71 and the conducting material 7 is 0.05 mm-10 mm.
Since the button 41 for turning on the toothbrush is disposed near the pressure sensing contact 71, when the button 41 is operated, the influence of the pressure of the button 41 on the distance between the pressure sensing contact 71 and the conductive material 7 should be considered, and corresponding parameters, such as the range of the preset value L, the elastic magnitude of the supporting frame 3, and the trigger pressure of the button 41, should be adjusted reasonably.
The invention can realize the detection of the tooth brushing pressure by a simple structure, can remind a user when the tooth brushing pressure is overlarge, and avoids the damage to teeth and gum caused by the overlarge pressure. The prompting modes of the invention are various, including indicator light flashing, indicator light color changing, vibration mode of the vibration motor changing or stopping, acoustic device sounding or changing sound. The parts for realizing the functions of the invention are mature devices with lower price and lower production cost.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
