Description

Technical Field

[0001] The utility model relates to the technical field of electric heating aromatherapy, in particular to an electric heating aromatherapy smoker. Background Art

[0002] Currently, most aromatherapy diffusers use electric heating to achieve aromatherapy atomization. Some achieve aromatherapy atomization by contacting an electric heating tube with a cotton wick containing essential oils; others achieve aromatherapy atomization by contacting a cotton wick with an electrothermal ceramic. For example, Chinese patent application number 202210467049.2 discloses an aromatherapy diffuser using a ceramic heating element atomizer. In this solution, the lower end of a microporous ceramic atomization core is offset against the upper extension of an essential oil cotton wick, electrically heating the microporous ceramic atomization core to achieve atomization of the essential oil cotton wick.

[0003] In the above scheme, the upper end of the essential oil cotton core is directly in contact with the microporous ceramic atomization core. Long-term high-temperature heating of the essential oil cotton core (cotton core) may cause the structure of the cotton core to become loose, and may even cause burning or carbonization, resulting in blackening of the color, affecting the cotton core's ability to adsorb and volatilize essential oils, resulting in less aromatherapy smoke generated by the entire aromatherapy device, affecting the use of the aromatherapy device. Summary of the Invention

[0004] In order to solve the deficiencies in the prior art, an electric aromatherapy smoker is provided which can prevent the cotton core from being scorched or carbonized.

[0005] The utility model is implemented by the following technical scheme: an electric aromatherapy smoker, comprising an aromatherapy smoker body, an aromatherapy atomization component provided in the aromatherapy smoker body, the aromatherapy atomization component comprising an essential oil storage tank for storing aromatherapy essential oil, the upper end of the essential oil storage tank being connected to an upwardly opening atomization hole, a cotton wick and an electrothermal ceramic part for atomizing the aromatherapy essential oil being provided in the atomization hole, the lower end of the cotton wick extending into the interior of the essential oil storage tank, a felt being provided between the cotton wick and the electrothermal ceramic part, the upper and lower ends of the felt respectively abutting against the cotton wick and the electrothermal ceramic part, so that the aromatherapy essential oil on the cotton wick is transferred to the side of the electrothermal ceramic part through the felt to be atomized.

[0006] During actual use, the cotton core will transfer the aromatherapy essential oil in the essential oil storage tank to the upper end of the cotton core through capillary reaction, and the essential oil on the upper end of the cotton core will be transferred to the felt through capillary reaction. The felt will transfer the aromatherapy essential oil to the side close to the electric heating ceramic part through capillary reaction. The heating of the electric heating ceramic part will realize the atomization of the aromatherapy essential oil on the felt, so that the electric aromatherapy smoker will produce aromatherapy smoke.

[0007] The electrothermal ceramic component may be any existing component consisting of a ceramic block and an electric heating wire.

[0008] This solution achieves the atomization of aromatherapy essential oils by placing felt between the electrothermal ceramic component and the cotton core through the contact between the felt and the electrothermal ceramic component. Since the felt has good high-temperature resistance, it is not easily burned or carbonized, thus avoiding the problem of the existing cotton core being burned due to direct contact with the electrothermal ceramic component, ensuring normal atomization of the aromatherapy atomization component.

[0009] Preferably, the cross-sectional area of ​​the electrothermal ceramic piece is smaller than that of the felt, the circumferential outer wall of the felt contacts the circumferential inner wall of the atomization hole, and there is a gap between the circumferential outer wall of the electrothermal ceramic piece and the circumferential inner wall of the atomization hole.
