And, starting from this low-frequency operating state, the brush head vibrates or rotates every time t33Is suspended once after the time of (1), and the time of suspension is t34Repeat m cycles. Gradually throwing out the water to achieve the aim of drying.
It is further preferred that the frequency of the brushhead is increased once per oscillation or rotation of the brushhead, beginning with the low frequency operating condition. The magnitude of the enhancement is preferably 10% -20%. The drying effect is better, and can not bring too big load to toothbrush itself.
Specifically, in this embodiment, the frequency of the high-frequency vibration (33000 times/min) reduced from step a31 to the low-frequency operating state is 19800 times/min, lasting 0.8 seconds (i.e., t)330.8 second) and then pause for 0.2 second (i.e., t)340.2 seconds). Entering the next cycle, wherein the second cycle has constant time and vibration frequency23100 times/min; entering the next cycle, wherein in the third cycle, the time is unchanged, and the vibration frequency is 26400 times/minute; entering the next cycle, wherein in the fourth cycle, the time is unchanged, and the vibration frequency is 29700 times/min; the next cycle was entered, and in the fifth cycle, the vibration frequency was 33000 times/min for 1 second. The optimum spin-drying is achieved at the fastest speed.
Of course, the actions, frequency and time of step a31 and step 32 are disclosed as being the most preferable, but are not limited thereto in other embodiments. Or the vibration of the brush head in the air can realize the throwing of the foam, and the foam can be directly dried in the air without being immersed in water.
