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 divided into several types: first, naturally volatile balm products; second, aroma diffusers that use perfume to diffuse fragrance; and third, blow-out type aroma diffusers that are used by clamping them to an air outlet. As shown in previously published Patent Document 1, a sealed aluminum foil is provided on the outside of a perfume bag, and the aluminum foil is provided with a pull tab with one end extending from the case. When in use, the aluminum foil is peeled off by pulling the pull tab outward to diffuse the fragrance. However, in this structure, the pull tab is made of one-piece molded aluminum foil, which is soft and easily bent and deformed. During the assembly and packaging process, the pull tab does not protrude from the case due to deformation or other reasons, which affects the user experience in the future, and the case must be opened before pulling the pull tab.

[0004] Next, many aroma diffuser products use an aroma-diffusing cotton pad and an absorbent stick to absorb perfume and then diffuse the scent, but this method of absorbing perfume with an aroma-diffusing cotton pad is prone to problems such as leakage due to spillage of 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.Furthermore, if the aroma-diffusing cotton pad and the absorbent stick are of a separate structure, poor contact between the two is likely to occur due to processing or assembly errors, which will affect the aroma diffusion.

[0017] The present invention has the following advantageous effects:

[0018] In the present invention, by adding a rotatable operating lever, the outer end of the operating lever is rotated outside the decorative cap, and the inner end of the operating lever peels off the peelable sealant that is attached to it during the rotation process. There is no need to remove the decorative cap before peeling off the peelable sealant. The entire operating process is simple and reliable, and the operating lever has a rigid structure and will not deform. That is, this avoids the problem that one end of the operating lever inevitably protrudes from the decorative cap during initial assembly, and the handle does not protrude from the case due to deformation, which results in a poor experience. This improves the user experience and makes operation more enjoyable.

[0019] Next, at least two volatile films are hot-pressed and fixed to form an aroma diffusing member, and a lead member is provided between the two volatile films during the hot-pressing process. When in use, the operating lever is first pressed to peel off the removable sealant, and then the elastic force applied downward by the elastic member is used to move the liquid-absorbing and aroma diffusing assembly downward, so that the lower end of the lead member is inserted into the mouth of the bottle and contacts the liquid-absorbing stick, and the perfume on the liquid-absorbing stick is guided upward to the lead member, and then guided to the aroma diffusing member and absorbed by the aroma diffusing member. After the aroma diffusing member absorbs the perfume, it slowly evaporates and diffuses the aroma, and after the volatile film absorbs the liquid, it only wets the membrane paper, and no liquid flows out. The mechanism of aroma diffusion by the volatile film does not cause the problem of perfume spilling, so the problems of leakage due to perfume spilling and contamination of the case are avoided, and the product has the characteristics of good aroma diffusing effect and good leakage prevention effect. The reed member and the volatile film are fixed by hot pressing to form an integrated assembly structure, which has a simple overall structure and good liquid guiding effect. Furthermore, by tightly adhering the reed member and the liquid-absorbing stick via an elastic member, the conventional structure in which the liquid-absorbing stick and the cotton pad for diffusing fragrance are made into a separate structure can be avoided, which is prone to poor contact due to processing or assembly errors and affects fragrance diffusion.

[0020] In addition, in the method of hot pressing and fixing the outer periphery of the volatile film, i.e., most of the area of ​​the volatile film is not hot pressed, firstly, the absorbed perfume can be tightly trapped within the hot pressed edge, thereby avoiding the problem of liquid spillage; secondly, the effect of directing the liquid inside the volatile film and the effect of diffusing fragrance can be avoided; at least one hot pressed point is arranged at a distance from the lead member of the two volatile films along the extension direction of the lead member at a position close to the lead member, so that the lead member can be well sandwiched and fixed between the two volatile films through the hot pressed point, and the non-hot pressed area other than the hot pressed point can better direct the perfume on the lead member into the volatile film.

[0021] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.
