Description

Technical Field

[0001] The invention relates to the technical field of fragrances, and in particular to a fragrance monomer. Background Art

[0002] With the development of the automobile industry, not only are higher requirements placed on technologies related to driving performance and environmental friendliness, but also from the perspective of drivers and passengers (users), there are also requirements for personalized needs during driving: for example, one of the personalized needs is to introduce a fragrance system in the cabin, so that users can enjoy the pleasure of driving in a space surrounded by fragrance.

[0003] The function realization process of the fragrance system is roughly as follows: the fragrance bottle containing the fragrance substance is matched and installed (such as plugged in) into the vehicle's fragrance system. In this way, when the fragrance system is started, the corresponding fragrance can be diffused in the vehicle's cabin.

[0004] However, the existing fragrance bottle structure is a bottle body (fragrance holder) + fragrance carrier (fragrance material is adsorbed in the fragrance carrier). The fragrance is usually diffused by opening a number of large holes in the bottle body structure to achieve internal and external convection of air to achieve the purpose of fragrance diffusion of the fragrance carrier in the bottle. Therefore, the fragrance bottles in the current car fragrance system basically use solid fragrance carriers to absorb fragrance as fragrance bodies, such as fragrance sticks, perfume creams, etc. The structure of the fragrance bottle cannot achieve the effect of sustained release of fragrance, which will greatly affect its service life and user experience. Secondly, the existing car fragrance system's fragrance diffusion methods include wind blowing and heating volatilization. Methods, etc., and different states of fragrance substances need to be configured for different fragrance diffusion methods. For example, the wind blowing method is preferably combined with a solid fragrance carrier, of course, it is also possible to combine it with a liquid or semi-gel state. However, the existing fragrance bottles with liquid fragrance substances inside are prone to leakage when used, and the heating method is generally used with liquid fragrance substances. Therefore, when the fragrance bottle is used as a refill for the car fragrance system, it cannot be well adapted to the car fragrance systems with different fragrance diffusion methods in different models, and has poor applicability. This also limits the development of the diversification of fragrance function types and the diversification of scenarios to a certain extent. Summary of the invention

[0005] In order to overcome the existing technical defects, the present invention provides a fragrance monomer: the structural features are more optimized, while ensuring that the fragrance molecules (fragrance raw materials or functional raw material molecules) can pass through and emit outward, the penetration rate can be limited, so that it can achieve the effect of uniform release for a longer time, thereby improving the service life; the fragrance types are richer, and it can be adapted to the car fragrance systems with different fragrance diffusion methods in different car models, with good applicability, and can also meet the diversified needs of different users for fragrance scenes.

[0036] like Figure 1 to Figure 2 As shown, the fragrance monomer provided by this embodiment includes a container 1 with a cavity inside and a columnar shape, and a fragrance material 2 arranged in the cavity and used for dispersing fragrance. The container 1 includes a tube body 10 and a cover body 11 connected by a threaded seal, a cavity is formed between the tube body 10 and the cover body 11, and a plurality of micropores with a pore size of 1 nanometer to 100 micrometers are densely distributed on the tube body 10 and / or the cover body 11, so as to slowly release the fragrance emitted by the internal fragrance material to the outside, and achieve the effect of fragrance penetration but no liquid leakage.

[0037] It is understandable that the container 1 can also be designed to be in the shape of a pill (such as Figure 3 shown).

[0038] It is understandable that the tube body 10 and the cover body 11 can also be connected by a tight fitting manner (such as Figure 4 shown).

[0039] In the above, a plurality of micropores with a pore size of 1 nanometer to 100 micrometers are provided on the tube body and / or the cover body, so that the container containing the fragrance substance can meet the requirements of sealing and fragrance permeability at the same time, so that the container can slowly release the fragrance emitted by the internal essence to the outside, and while ensuring that the molecules of the fragrance or functional raw material can pass through, it can also limit its permeation rate, so that it can achieve the effect of uniform release for a longer time, thereby improving the service life; secondly, by utilizing the characteristics of the container, liquid, semi-fluid or solid fragrance substances can be accommodated inside it without leakage problems, so that the fragrance monomer can be adapted to the use of vehicle-mounted fragrance systems with different fragrance diffusion methods in different models according to the state of the contents, and the state of the fragrance substance in the fragrance monomer can also be selected according to different usage scenarios and user needs, and the applicability is good.
