Abstract: The present disclosure provides a fan, a holder and a support leg of a holder. The support leg includes a rotational seat; a reinforcing piece where one end of the reinforcing piece inserted into the rotational seat and the reinforcing piece is bendable; and a soft leg sleeve sleeved on the reinforcing piece. The reinforcing piece and the rotational seat of the support leg are integrally formed to ensure more stable connection; the assembly of the support leg can be completed simply by sleeving the leg sleeve on the reinforcing piece. In addition to normal supporting effect, the support leg can also be held by hand or wound on another support piece based on different scenarios, bringing flexible and rich functions.

Abstract: The present disclosure provides a dual-purpose mosquito repeller for a mosquito-repellent incense tablet and a mosquito-repellent incense liquid, including: a mosquito repeller body. The mosquito repeller body includes: a mosquito-repellent incense tablet heating unit, configured to heat the mosquito-repellent incense tablet to produce a mosquito-repellent smoke; a mosquito-repellent incense liquid heating unit, configured to heat the mosquito-repellent incense liquid to produce a mosquito-repellent smoke. A level switch for switching the mosquito repeller to a different working state is disposed between the mosquito-repellent incense tablet heating unit and the mosquito-repellent incense liquid heating unit. Each level of the level switch corresponds to one working state.

Abstract: The embodiments of the present disclosure provide a rotational electric fan including a fan head and a fan holder, wherein the fan head and the fan holder are connected through a rotational structure. The rotational structure includes: a fitting structure, including a circular cover fitting groove disposed on the fan head and a circular fitting head disposed on the fan holder and cooperating with the circular cover fitting groove, so as to fit the fan head and the fan holder together; a circular spacer, fixed on a surface of the circular fitting head facing toward the fan head and being in interference contact with a surface of the circular cover fitting groove facing toward the circular fitting head, so as to support rotational movement of the fan head relative to the fan holder.
