Description

Technical Field

[0001] The utility model belongs to the technical field of household or vehicle-mounted aromatherapy, and particularly relates to an aromatherapy host and an aromatherapy machine. Background Art

[0002] Aromatherapy is a product used in indoor and car environments to improve the smell of the air. With the improvement of living standards, more and more people accept and use aromatherapy products. In order to improve the air environment in private cars and indoors, people usually place solid air fresheners, spray perfumes or place aromatherapy essential oils in the car or indoors to make the space fragrant, eliminate the user's fatigue, and liven up the atmosphere in the space. Accompanied by soft music, the nose can smell the fresh and sweet floral fragrance, which penetrates into the bone marrow and floats, enhancing the pleasure.

[0003] The existing aromatherapy machine generally adopts an independently installed aromatherapy tank as a refill, that is, when the fragrance substance in the aromatherapy tank is consumed, the aromatherapy tank is replaced and continued to be used. First of all, the overall structure of the existing aromatherapy tank is complicated, a cavity for accommodating the fragrance substance is provided inside it, and then air inlet and air outlet holes connected to the cavity are provided at the upper and lower ends, so that the air flowing through it contacts the fragrance substance to form a fragrance. However, in order to avoid the fragrance substance from clogging the air inlet and air outlet holes, the internal structure of the cavity is complicated, the fragrance substance needs to be suspended, and a gap needs to be ensured between the fragrance substance and the air outlet, which makes it inconvenient to refill the aromatherapy tank. Secondly, the air flows directly through the interior of the aromatherapy jar. Although it can achieve a good fragrance diffusion effect, it is easy to cause choking due to excessive fragrance diffusion. In addition, the internal fragrance substances are consumed too quickly, with a short service life and the need for frequent replacement. In addition, the aromatherapy machine is generally divided into two detachable upper and lower layers. After removing the upper layer, the aromatherapy jar is loaded from top to bottom into the lower layer for use. This operation method undoubtedly increases the trouble of replacement and replenishment, is not simple enough, and leads to a poor user experience. In addition, it can basically only be used for aromatherapy jars of one size and matching shape, and has poor applicability.

[0004] Secondly, when existing aromatherapy machines use liquid perfume or fragrance as the fragrance material, they generally use absorbent cotton cores and / or fragrance-dispersing cotton sheets to absorb the perfume and then directly expose it to the naked air for volatilization and fragrance dispersion. During the use of the fragrance dispersion, it is easy to cause spillage and leakage due to tipping. Utility Model Content
