TECHNICAL FIELD

[0001] The present application relates to the technical field of cosmetic instruments, in particular to a multi-electrode cosmetic instrument and a dynamic method thereof. BACKGROUND

[0002] In recent years, cosmetic instruments have appeared on the market, which are in close contact with the skin of the user and flow weak current to the skin to exert massage effect and other cosmetic effects. These cosmetic instruments flow current of different frequencies and amplitudes to the skin of the user by applying electricity to the electrodes, stimulate the human skin, and thus produce different effects. Moreover, the experience of the user is different due to different activation methods of the electrodes on the cosmetic instrument.

[0003] However, some cosmetic instruments on the market that use weak current to produce a sense of use on the skin of the user only have a single electrode, and usually can only apply a specific voltage to produce effective stimulation by the frequency of the voltage, only lasting constant body feeling, thus lacking massage effect, and lacking a sense of use on the skin of the user. Some cosmetic instruments are provided with multiple electrodes, but only two effective electrodes in these electrodes, which are only dispersed to each electrode point, which may result in a monotonous sense of use, and the experience of the user is still very limited.

[0004] Some cosmetic instruments with multiple electrodes and electrodes activated in a specific way have a certain direction, such as rotation. The invention with publication number CN105263460B provides a cosmetic instrument to improve the close contact with the skin of the user and enable the user to feel a more rhythmic massage effect. However, this method cannot flexibly adjust the activation order of the electrodes according to the use habits of the user. Therefore, in the past cosmetic instruments, the product has limitations in improving the skin feeling of the user during use.

[0005] Therefore, we propose a multi-electrode cosmetic instrument and a dynamic method thereof. SUMMARY

[0006] In view of the above deficiencies in the prior art, the present application provides a multi-electrode cosmetic instrument and a dynamic method thereof, which can flexibly set the activation method of each electrode according to the use mode of the user, improve the close contact with the skin of the user, and enable the user to feel a rich experience effect.

[0007] The present application provides the following technical solution: a multi-electrode cosmetic instrument, comprising at least four electrode heads for stimulating the skin, and each electrode head has a voltage-adjustable drive circuit for outputting current of different frequencies and amplitudes. The cosmetic instrument contains an acceleration sensor for obtaining the direction of gravity and the moving direction of the cosmetic instrument.

[0008] A dynamic method of a multi-electrode cosmetic instrument, comprising the following contents:

[0009] S1, when the beauty instrument is picked up, the acceleration sensor in the body acquires the value of the instantaneous acceleration, and judges the gravity direction of the beauty instrument;

[0010] S2, when the beauty instrument is close to the user's skin, the resistance changes, the load condition of each electrode is detected, and it is judged that the electrode has effectively contacted the skin;

[0011] S3, when the beauty instrument is close to the user's skin and moves, the change of acceleration is acquired through the acceleration sensor in the host, the moving direction of the instrument is acquired, and the moving direction of the user is combined with the electrode direction to set the energizing order and amplitude of the electrode;

[0012] S4, when a certain direction is obtained from the acceleration, multiple electrodes correspond to the direction, and the energizing order presents an arrow shape, and the amplitude gradually increases, so that the user obtains a stimulation feeling consistent with the moving direction of the beauty head.

[0013] Preferably, the acceleration refers to three mutually perpendicular components, i.e. three axes, which are counted as and the acceleration value is acquired from the three axes, and the included angle is calculated through the formula:

[0014] Preferably, the state of the electrode and the skin is judged through the formula calculation: If the above conditions are met, the angle at this time can be counted into the use angle set, and the actual use angle set is obtained and the preset angle set is operated. Generally, most of the angles intersect, that is, whether these angles are within the preset angle range is judged. If part of the angle is within a certain preset range, it can be judged that the user uses the device in what scene. After the scene in which the user uses the device is determined, the parameters corresponding to the scene can be used.

[0015] Preferably, when the user holds the beauty instrument close to the skin and moves, the positive and negative electrodes of the electrode head located in the straight line of the moving direction are energized, and the amplitude gradually increases.

[0016] Compared with the prior art, the present application has the following beneficial effects:

[0017] The multi-electrode beauty instrument and the dynamic method thereof maintain the use behavior of the user through the acceleration sensor in the beauty instrument, and set the energizing mode of the electrode head. When the beauty instrument moves on the skin surface, the energizing direction of the electrode head is consistent with the moving direction. The present application enables the beauty instrument to produce a multi-electrode stimulation experience consistent with the user's behavior, and improves the diversity of the experience.
