DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0029] Referring to FIGS. 1-6, a diffuser product in accordance with the present invention comprises an absorbent paper structure component 3, at least one aromatic substance, and at least one breathable film 5. The absorbent paper structure component 3 comprises an absorbent paper 30. The absorbent paper 30 has pores 31, and micro air channels (not shown) formed between the pores 31 for creating capillary effects.

[0030] The at least one aromatic substance is releasably filled in the pores 31 of the absorbent paper structure component 3.

[0031] The at least one breathable film 5 has a plurality of micropores that are waterproof and breathable. The breathable film 5 is bonded to the outer side of the absorbent paper 30 or the absorbent paper structure component 3.

[0032] In this way, the breathable film 5 can shield the absorbent paper structure component 3 in a waterproof and breathable manner, and is used to adjust the aromatic substance to contact with the outside air, thereby controlling the release rate of the aromatic molecules evaporated by the aromatic substance through the breathable film 5 and also controlling the outside moisture from penetrating into the inside of the absorbent paper structure component 3.

[0033] The breathable film 5 is a microporous film that is used to restrict the release of some of the aromatic substance to the outside while the micropores of the breathable film 5 allow some of the aromatic substance to gradually diffuse into the environmental space at a stable rate.

[0034] By adjusting the release rate of the appropriate amount of the volatile aromatic substance, it can delay the aroma diffusion time of the diffuser product, provide a stable and effective aroma to the space, and overcome the problem that the diffuser product consumes the aromatic substance too quickly in the early stage of use and the problem of insufficient concentration in the later stage.

[0035] The breathable film 5 is a waterproof and moisture-permeable microporous film. Therefore, the breathable film 5 not only can shield the absorbent paper structure component 3 in a waterproof and breathable manner and adjust the aromatic substance to contact with the outside air to further control the release rate of the aromatic molecules evaporated by the aromatic substance through the breathable film 5 but also can control the outside moisture from penetrating into the inside of the absorbent paper structure component 3 to maintain the quality of the absorbent paper structure component 3.

[0036] The matrix material of the absorbent paper 30 of the absorbent paper structure component 3 includes, but is not limited to, for example, pulp, pulp compounds, pulp compositions, fibers, and etc. Pulp may include fibers and raw materials but is not limited to wood fibers, and other plant fibers such as roots, stems or leaves of various herbs, manuscript rods, hemp, cotton, bagasse or peel fibers. This matrix material can form the absorbent paper 30 of the absorbent paper structure component 3.

[0037] The aromatic substance includes an aromatic odor composition, a volatile substance, or a liquid aromatic substance, such as a fragrance or fragrance composition, an aromatherapy compound, a water-based fragrance, or a natural oil, etc. These include volatile substances that can be transmitted to the olfactory system and can include one or more aromatic characteristics, such as fragrance ingredients such as top notes, middle notes or base notes. These fragrance ingredients or their compositions are often used, such as various raw materials or compositions including but not limited to essential oils, aromatic essential oils, various flavors, flower essences, gels or sesame oils or fragrances, or their liquid aromatic substances. Those skilled in the art can know the use.

In addition to the breathable and waterproof properties, in some embodiments, the film properties themselves can be attached or adsorbed or coated and bonded to the outer side of the absorbent paper structure component 3 or absorbent paper 30. By bonding the breathable film 5 to the outer side of the absorbent paper 30 or absorbent paper structure component 3, the ductility or elasticity of the breathable film 5 can allow the diffuser product to strengthen the solidity and increase the mechanical properties such as toughness, thereby improving the quality of use.

[0039] Referring to FIGS. 4-7, according to some embodiments of the present invention, the breathable film 5 is bonded to at least a part or all or the end of the outer side of the absorbent paper 30 or absorbent paper structure component 3, or it is bonded with the outer side of the absorbent paper structure component 3 at intervals.

[0040] Referring to FIGS. 1-6, according to some embodiments of the present invention, the absorbent paper structure component 3 can be, but is not limited to, a paper roll, a paper stick, a paper piece, a paper block, a two-dimensional paper product, a three-dimensional paper product or a geometrically shaped absorbent paper structure component. The absorbent paper structure component 3 can be, but is not limited to, a paper stick, and the paper stick can be a paper roll or a single structural paper stick made by casting. In some embodiments, the absorbent paper 30 has a first surface 33 and a second surface 35. The first surface 33 and the second surface 35 have the same porosity, the same number of pores, or the same pore size. An absorption gradient is formed between the layers, so that the absorbency of the absorbent paper structure component 3 increases from the inner layer to the outer layer, or the absorbency decreases from the inner layer to the outer layer. This absorbent paper structure component 3 absorbs aromatic substances, such as liquid aromatic substance essences or essential oils or sesame oil. The outer layer absorbs more than the inner layer and can smoothly fill the fragrance to the inner layer or release the aromatics without hindrance. The product manufacturing process can be efficient and rapid.

[0041] Referring to FIGS. 1-3 and FIGS. 6 and 7, in some embodiments of the present invention, the absorbent paper structure component 3 is a rolled paper stick 300.

The planar paper has a first surface 33 and a second surface 35. The first surface 33 and the second surface 35 have the same porosity, the same number of pores, or the same pore size. There is the same or close absorption between the layers of the rolled paper stick 300. The absorption gradient between the layers of the rolled paper stick 300 can increase from the inner layer to the outer layer or decrease from the inner layer to the outer layer. This rolled paper stick 300 absorbs aromatic substances, such as liquid aromatic substance essences or essential oils or sesame oil. The outer layer absorbs more than the inner layer and can smoothly fill the fragrance to the inner layer or release the aromatics without hindrance. The product manufacturing process can be efficient and rapid.

[0042] Referring to FIGS. 5-7, in one embodiment of the present invention, the breathable film 5 is a peelable, breathable film, whereby, at a later stage of the use of the diffuser product, the evaporation rate of the aromatic substance is weakened, and at least a part of the breathable film 5 is peeled off from the outer side of the absorbent paper structure component 3 to enhance the release rate of the aromatic substance.

[0043] In some embodiments of the present invention, the absorbent paper structure component 3 can be, but not limited to, a paper stick that can be a rolled paper stick 300 or a single structure paper stick made by casting. The single structure paper stick can be made of pulp or a pulp composition by casting.

[0044] In some embodiments of the present invention, the breathable film 5 is a multilayer film. In some embodiments, the breathable film 5 is, for example, a film of two, three or more layers bonded to the outer side of the absorbent paper structure component 3 which absorbs the aromatic substance, so that the breathable film 5 adjusts the release of the aromatic substance, such as volatile top notes, meddle notes, or base notes. Among them, the natural essential oils of the top notes have a strong diffusive force and volatilize quickly. The multiple layers of the breathable film 5 can be used to shield the volatile composition of this diffuser product in a waterproof and breathable manner to formulate and optimize the mixed release rate of various volatile compositions including top notes, middle notes and base notes. Through the multi-layer structure, the volatile top note is blocked to release slowly, and at the same time, other volatile combinations such as middle and base notes are released simultaneously in the space formed between the layers of the breathable film 5, or the volatile combinations are released over time in a staggered manner.

[0045] Referring to FIGS. 1-7, in some embodiments of the present invention, a diffuser product manufacturing method includes the steps as follows:
