Abstract: A drive motor includes a housing and a stator iron core arranged inside the housing. A rotor iron core is placed through the inside of the stator iron core. The rotor iron core includes a cylindrical iron core body, and two openings are symmetrically formed on a periphery of the iron core body in a radial direction of the iron core body. The iron core body is provided with a plurality of mounting slots for receiving magnets, and each of both sides of the mounting slot is provided with a magnetic-leakproof air slot. The central part of the iron core body is provided with a through hole into which a rotating shaft is inserted. Moreover, the magnets are mounted in the mounting slots by means of insertion.

Abstract: A control method and control system for a smart toothbrush. An App terminal reads the tooth brushing scheme of the cloud. The App terminal recommends a matched tooth brushing scheme according to personal information of a user. Finally, based on the user's selection, the recommended tooth brushing scheme is pushed to the smart toothbrush for parameter adjustment. Alternatively, a customized or re-selected tooth brushing scheme is pushed to the smart toothbrush for parameter adjustment. The control method and control system for the smart toothbrush meet many tooth brushing needs for different people, improving the applicability of the smart toothbrushes.

Abstract: The invention discloses a water toothpick, which includes a high-pressure gas generator, a water tank, a valve, a nozzle assembly and a water supply, wherein the high-pressure gas generator is communicated with the nozzle assembly, the valve is arranged between the high-pressure gas generator and the nozzle assembly, and the water supply is respectively communicated with the water tank and the nozzle assembly, so as to convey water in the water tank to the nozzle assembly. When the water toothpick is used, the high-pressure gas generator transmits generated high-pressure gas to the valve, and after a certain amount of water is stored in the nozzle assembly, the valve is opened, and the high-pressure gas at the valve is instantaneously discharged into the nozzle assembly, mixed with the water in the nozzle assembly to form compressed vapor, and then sprayed out from the nozzle assembly to complete one cleaning action.
