Description

[Technical field]

[0001] The present invention relates to the technical field of aroma diffusers for home or car use, and in particular to an aroma diffuser. [Background technology]

[0002] Aroma diffusers are products used to improve the smell of air in indoor and car environments, and as living standards improve, more and more people are accepting and using aroma diffuser products. To improve the air environment in personal cars and indoors, people usually place solid air fresheners, spray perfume, or place aromatic essential oils in the car or indoors, which spread the scent throughout the space, relieving the user's fatigue and creating a fun atmosphere in the space. Combined with soft music, the fresh, floral, sweet scent penetrates the nose and bones, creating a subtle fragrance and enhancing enjoyment.

[0003] However, conventional aroma diffuser products are mainly classified into several types, the first being a naturally volatile balm product, the second being an aroma diffuser that uses perfume to diffuse the scent, and the third being a blow-out type aroma diffuser that is used by clamping it to the air outlet. Most aroma diffuser products diffuse the scent after absorbing the perfume using an aroma-diffusing cotton pad and a liquid-absorbing stick, but the method of absorbing the perfume and diffusing the scent with an aroma-diffusing cotton pad is prone to problems such as leakage due to spillage of the liquid from the aroma-diffusing cotton pad and contamination of the inside of the case when the aroma diffuser falls over or the vehicle is vibrated, and when the aroma-diffusing cotton pad and the liquid-absorbing stick are of a separate structure, there is a problem that poor contact between the two is likely to occur due to processing or assembly errors, which affects the aroma diffusion.

[0006] In addition, the aroma diffusion member is formed by hot pressing two laminated volatile films, the lead member is provided at the center of the aroma diffusion member, the outer periphery of the two volatile films is fixed by hot pressing, and at least one hot press point is provided at a distance from the other at a position close to both sides of the lead member on the two volatile films along the extension direction of the lead member.

[0007] In addition, the aroma diffusion member is formed by stacking four volatile films in a cross shape and hot pressing, the lead member is located at the center of the cross of the aroma diffusion member, each of the volatile films is right-angled, the right-angled vertices of the four volatile films overlap at the center of the cross, and the right-angled sides of the four volatile films are stacked two at a time and fixed by hot pressing, the outer peripheries of two adjacently stacked volatile films are fixed by hot pressing, and at least one hot pressing point is provided at a distance along the extension direction of the lead member at a position close to both sides of the lead member of the two adjacently stacked volatile films.

[0008] Furthermore, four guide grooves arranged in a cross shape are formed on the inner wall of the decorative cap, and the outer ends of the fragrance diffusing members are slidably fitted into the guide grooves.

[0009] In addition, the upper end of the bottle is provided with a fitting portion that shrinks inward and fits with the decorative cap, and at least one pair of engagement grooves are recessed on the outside of the fitting portion and spaced apart vertically.

[0010] In addition, at least two sets of locking grooves are provided symmetrically arranged on the outside of the fitting portion, each set of locking grooves having two locking grooves spaced apart vertically, and at least two locking devices are protruded onto the inside of the decorative cap, one for engaging with each set of locking grooves.
