Abstract: A mosquito repeller includes a casing, a mosquito repellent liquid bottle, and a first heating element installed in the casing. The first heating element includes a first heat-generating body and a cotton swab. The first heat-generating body is inserted into the cotton swab, and an end of the cotton swab away from the first heat-generating body extends into the mosquito repellent liquid bottle. Since the first heat-generating body is inserted into the cotton swab, heat is concentrated at the center of the cotton swab, and the cotton swab is heated uniformly, and the vaporization of the mosquito repellent liquid is stable to improve the mosquito repelling effect of the mosquito repeller, while reducing the power consumption of the mosquito repeller, saving energy, avoiding a temperature rise of components near the heat-generating components, retarding the ageing of components, and extending the service life of the mosquito repeller.

Abstract: A beverage aeration apparatus is used to generate air bubbles within a contained beverage, preferably wine, to enhance the overall visual appeal of the wine. The apparatus is also configured to improve the overall scent of the wine by providing contact with air, which stimulates the release of various fragrant tones contained within the wine. A pump connected to a hose provides a constant flow of air into the bottom of a wine glass, thus allowing that air to flow up through the wine and gather smells and scents contained within. The bubbles may be controlled to flow at different rhythms or rates to provide an interesting visual pattern for the user to observe. Furthermore, the apparatus may be configured to provide spray nozzles or tools to cause the wine to eject at various angles and pressures, thus providing a dazzling wine show within the wine glass.
