Description

[Technical field]

[0001] The present invention relates to the technical field of aroma diffusers, and in particular to a blow-out type aroma diffuser. [Background technology]

[0002] As people's living standards improve, the number of households owning private passenger cars continues to increase. In order to improve the air environment inside private passenger cars, people usually place solid air fresheners, spray perfume, or place aromatic essential oils inside the car, which fills the inside of the car with fragrance, relieving the fatigue of the driver and passengers, creating a pleasant atmosphere in the space, and improving the enjoyment of driving.

[0003] However, conventional blow-type aroma diffusers that use fragrance-dispersing pieces to diffuse fragrance have a complex structure. After the internal fragrance-dispersing pieces lose their fragrance, it is necessary to frequently replace the fragrance-dispersing pieces or add perfume to them. Furthermore, when replacing the fragrance-dispersing pieces or adding perfume, the entire blow-type aroma diffuser must first be disassembled, making the entire process complicated. In addition, the method of using an absorbing wick to absorb perfume and diffuse the fragrance is prone to problems such as leakage and overflow.

[0004] Regarding the above problem, there is a conventional structure that combines a fragrance sachet and a breathable film inside to achieve fragrance diffusion. As shown in Patent Document 1, which was previously published, a sealed aluminum foil is integrated inside the fragrance sachet, and a breakthrough element is provided between the breathable film and the aluminum foil to break through the aluminum foil, thereby allowing the perfume to flow out and diffusing the fragrance. In this method, the aluminum foil, the breakthrough element, and the breathable film are integrated inside the fragrance sachet, making the overall structure complicated and difficult to manufacture and process, and the breakthrough element comes into direct contact with the aluminum foil, which creates a risk of accidentally breaking through the aluminum foil during the manufacturing and assembly process. In addition, this structure does not have an air flow rate adjustment member, and the intake hole is always open, which means that the amount of air intake and the amount of fragrance diffusion cannot be adjusted, and the fragrance diffusion effect is always at its maximum, which causes a large waste of power when it is not needed, which has a significant impact on the lifespan. [Prior art documents] [Patent documents]

[0023] In order to more fully understand the technical contents of the present invention, the present invention will be further introduced and described with reference to the drawings and specific embodiments. In this specification, the terms "first", "second", etc. are only intended to distinguish different elements, and do not imply order, and do not limit that "first" and "second" are different types.

[0024] The technical means in the embodiments of the present invention will be described in detail below with reference to the accompanying drawings in the embodiments of the present invention, but it goes without saying that the described embodiments are only some of the embodiments of the present invention and do not include all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without any creative activity are all within the scope of protection of the present invention.

[0025] 1 to 12, the blow-out type aroma diffuser according to this embodiment comprises a case 1 having a hollow portion 10, a perfume container 2 for storing fragrance that is provided inside the case 1, and a clip 3 that is removably provided on the outside of the rear end of the case 1, so that the blow-out type aroma diffuser can be clamped to the exhaust hole of the car's air conditioner by the clip 3, and the aroma diffusion effect can be improved by the wind blown out from the exhaust hole of the car's air conditioner. A plurality of air intake holes 11 that communicate with the hollow portion 10 are provided at the rear end of the case 1, and the air intake holes 11 can be used for both intake and exhaust at the same time. The rear end of the perfume container 2 is an opening, and a breakable seal 21 made of a liquid-impermeable material is provided at the opening, and a volatile film located outside the breakable seal 21 is also provided at the rear end of the perfume container 2, and the breakable seal 21 and the volatile film 22 are provided in close contact with each other, and since the thickness of the breakable seal 21 is thinner than that of the volatile film 22, the breakable seal 21 is configured to break with less elongation than the volatile film 22 when an external force is applied to the volatile film 22 from the outside in the thickness direction. An elastic break-through structure that bends and moves inward after receiving an external force and presses the volatile film 22 and the breakable seal 21 is integrally provided at the rear end of the case 1, and the breakable seal 21 is deformed during the compression process and then broken, so that the perfume in the perfume container 2 flows out from the broken part to the volatile film 22 and volatilizes, diffusing the fragrance.

[0026] In the above structure, the perfume container containing the fragrance is used as the fragrance-dispersing body, and when the fragrance-dispersing piece is used to absorb the perfume and diffuse the fragrance, the problems of continuously adding perfume or replacing the fragrance-dispersing piece are avoided, i.e., the case disassembly process is omitted, and the overall structure is simple. In addition, a breakable seal is provided at the opening side of the perfume container, and the perfume container is sealed with the breakable seal before it is opened, thereby avoiding the problem of perfume being wasted due to evaporation of perfume in the perfume container; when in use, the elastic break-through structure is pressed backward and then compressed, and the volatile film and the breakable seal are compressed; during the compression and deformation process, the compressed part of the breakable seal is broken, but the volatile film is not broken, so that the perfume in the perfume container flows out from the broken part of the breakable seal and is absorbed by the volatile film, and then evaporates slowly to diffuse the fragrance, so that the fragrance of the in-car blow-out type aroma diffuser lasts for a long time, and perfume is not wasted, and it has the characteristics of good fragrance diffusion effect, long fragrance duration and good leakage prevention effect; the elastic break-through structure is integrated with the case, the overall structure is simple and easy to process and assemble, and there is no risk of the breakable seal being accidentally broken during assembly.
