Description

Technical Field

[0001] This utility model relates to the field of aromatherapy equipment technology, and in particular to a ceramic disc coupled constant temperature aromatherapy machine. Background Technology

[0002] Most aroma diffusers on the market currently use metal or glass trays to hold essential oils. However, due to the limited thermal conductivity, corrosion resistance, and molding stability of these materials, problems such as uneven heating, overheating and decomposition of essential oils, and tray corrosion or deformation are prone to occur. Furthermore, the heating control of some aroma diffusers is not precise enough, resulting in unsatisfactory aromatherapy effects and even affecting product lifespan and user experience. Therefore, there is an urgent need to develop an aroma diffuser with a reasonable structure, high thermal conductivity, corrosion resistance, and precise temperature control. Utility Model Content

[0003] The purpose of this invention is to provide a ceramic disc coupled constant temperature aroma diffuser. Through the coupling structure between the ceramic disc and the aluminum alloy substrate, efficient heat conduction and corrosion resistance of essential oils are achieved. Combined with a temperature sensor and a flexible electric heating film, precise constant temperature control is achieved. Technical solution

[0004] A ceramic disc coupled constant temperature aroma diffuser includes a shell, a ceramic disc, an aluminum alloy substrate, a flexible electric heating film, a temperature sensor, a heat insulation pad, a control circuit, and a power module. The ceramic disc has a groove at the bottom and the aluminum alloy substrate has a raised disc at the top that matches the groove. The inner diameter of the groove is larger than the diameter of the disc and the height of the disc is equal to the depth of the groove, so that the ceramic disc and the substrate are in planar coupling contact, which facilitates replacement and efficient heat conduction. The flexible electrothermal film and temperature sensor are sequentially attached to the underside of the substrate, and the heat insulation pad covers the underside of the substrate. The control circuit is connected to the temperature sensor and the electrothermal film to achieve constant temperature control.

[0005] Furthermore, the power module supplies power to the system, and the control circuit enables real-time adjustment of the heating temperature to ensure a constant essential oil evaporation temperature.

[0006] The advantages of this invention are: simple structure, easy-to-replace and corrosion-resistant ceramic disc, high thermal conductivity of the substrate, precise temperature control, effective prevention of essential oil overheating and decomposition, and improved aromatherapy experience and product lifespan.
