Description

Technical Field

[0001] The present invention relates to the technical field of porous ceramic materials and fragrance environments, and more specifically, to a fragrance ceramic element. Background Art

[0002] At present, people like to create a comfortable environment with a fresh and slight fragrance in cars, homes, hotels, beauty salons, offices, clubs and other occasions to improve the air quality, please the body and mind, regulate emotions, soothe the mood, invigorate the spirit, and enjoy a romantic life and happy work.

[0003] The fragrance ceramic element is a core element of a product that releases a fresh and subtle fragrance. Its basic principle is to absorb the fragrance liquid from the bottle into the element body through the uniform internal pores, and then the element body will gradually evaporate evenly to spread the fragrance. The fragrance evaporates through the fragrance ceramic element, and the fragrance is full but not overwhelming. Its main function is to store fragrance oil (water) and help the fragrance oil to spread. The fragrance ceramic element plays the role of "absorption and volatilization" to keep the fragrance evenly.

[0004] People usually use traditional rattan, fiber rods, gypsum, common silicate porous ceramics and other materials to prepare aroma ceramic components. Although the aroma ceramic components prepared by these materials can basically meet the use requirements, there are still some shortcomings, such as being easily dissolved by fragrant oil, which will affect the smell of fragrant oil, absorbing a large amount of fragrant oil (water), but the effective fragrance retention time is short. Therefore, it is urgent to design an aroma ceramic component with strong oil (water) locking ability and stable volatilization to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a fragrance ceramic element, by which the stored fragrance oil (water) can be slowly volatilized, and has the characteristics of strong oil (water) locking ability, long-lasting fragrance, uniform and stable volatilization, and slow loss.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A fragrance ceramic element comprises an element body, wherein the element body is provided with a surface layer and an inner layer from the outside to the inside, the surface layer and the inner layer are provided with pores, the pore diameters of the pores of the surface layer and the pore diameters of the pores of the inner layer are both 30 to 1000 nanometers, and the through-porosity of the surface layer and the inner layer is both 20 to 60%.

[0008] Furthermore, the pores of the surface layer and the pores of the inner layer both have a pore diameter of 30 to 300 nanometers.

[0009] Furthermore, the pore size of the surface layer is smaller than the pore size of the inner layer.

[0010] Furthermore, the cross-section of the element body is any one of a solid square, a circle, a ring, and a hollow square.

[0011] Furthermore, a cavity is provided at the center of the element body along its extension direction.

[0012] Furthermore, sealing plates are provided at both ends of the cavity.

[0013] Furthermore, a fiber cotton swab is provided in the cavity.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model provides a fragrance ceramic element, which is provided with an element body, and the element body is provided with a surface layer and an inner layer from the outside to the inside, and pores are provided in the surface layer and the inner layer, and the pore diameters of the pores in the surface layer and the pore diameters of the pores in the inner layer are both 30 to 1000 nanometers, and the through-porosity of the surface layer and the inner layer is both 20 to 60%. The element has a strong oil (water) locking ability by providing mutually conductive nano-scale pores inside the surface layer, inside the inner layer, and between the surface layer and the inner layer, so that the stored fragrance oil (water) evaporates slowly, locks the fragrance, and keeps the fragrance for a long time, the fragrance is pure, the volatilization is uniform and stable, the effective time is long, and the fragrance is slowly lost.

[0025] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods, but does not constitute any limitation to the present invention.

[0026] Reference Figure 1 and 2 As shown, a fragrance ceramic element of the utility model comprises an element body 1, wherein the element body 1 is provided with a surface layer 2 and an inner layer 3 from the outside to the inside, and pores 4 are provided in the surface layer 2 and the inner layer 3, and the aperture of the pores 4 of the surface layer 2 and the aperture of the pores 4 of the inner layer 3 are both 30 to 1000 nanometers, and the through-porosity of the surface layer 2 and the inner layer 3 are both 20 to 60%. The fragrance ceramic of the utility model is provided with mutually conductive nano-scale pores 4 inside the surface layer 2, inside the inner layer 3, and between the surface layer 2 and the inner layer 3, and the through-porosity of the pores 4 of the surface layer 2 and the pores 4 of the inner layer 3 are also the same, so that the fragrance oil (water) is strongly locked, the fragrance oil (water) stored is slowly volatilized, the fragrance is locked, the fragrance is long-lasting, the fragrance is pure, the volatilization is uniform and stable, the effective time is long, and the fragrance is slowly lost.

[0027] Furthermore, the pores 4 of the surface layer 2 and the pores 4 of the inner layer 3 have pore diameters of 30 to 300 nanometers. When the pore diameter of the porous ceramic is below 300 nanometers, the fragrance retention effect is better.

[0028] Furthermore, the pores 4 of the surface layer 2 have a smaller aperture than the pores 4 of the inner layer 3 , which can further slow down the volatilization speed of the fragrance oil (water) and prolong the fragrance retention time.

[0029] Furthermore, the cross section of the element body 1 is any one of a solid square, a circle, a ring, and a hollow square, so that elements of various shapes can be manufactured.

[0030] Further, see Figure 3-4 As shown, a cavity 5 is provided at the center of the component body 1 along its extension direction. The cavity 5 can be used to make the bottom of the component body 1 contact with more fragrance oil (water) to enhance its adsorption effect.

[0031] Furthermore, sealing plates 6 are provided at both ends of the cavity 5. The sealing plates 6 at both ends can prevent the fragrance oil (water) injected into the cavity 5 from volatilizing from both ends thereof, so as to ensure the volatilization effect.

[0032] Furthermore, a fiber cotton swab 7 is provided in the cavity 5, and the fiber cotton swab 7 can further retain the fragrance oil (water) and prolong the fragrance retention time.

[0033] Experimental example

[0034] Four porous ceramic elements with different pore sizes were selected as fragrance ceramic elements numbered 1 to 4. Their weights were measured and then they were soaked in the same fragrance oil. After soaking, the weight of each fragrance ceramic element was measured. Each fragrance ceramic element was placed in a room with the same environment. The fragrance retention was observed every day. Finally, the fragrance retention time of each fragrance ceramic element was counted, the oil absorption of each fragrance ceramic element and the ratio of fragrance retention time to oil absorption were calculated, and the comparative experimental situation table of each fragrance ceramic element was obtained as shown in Table 1:

[0035] Table 1 Comparative experimental results of various fragrance ceramic components

[0036]

[0037] According to Table 1, when the through-hole diameter in the porous ceramic is below 300 nanometers, the ratio of the fragrance retention time and the amount of absorbed fragrance oil (water) per unit volume of the fragrance ceramic element is larger than that of the fragrance ceramic element with a large pore diameter of more than 300 nanometers, which indicates that the fragrance function of the fragrance ceramic element is stronger. It can be said that the smaller the through-hole diameter, the less the amount of fragrance oil (water) absorbed by the ceramic element, but the fragrance retention time per unit oil weight is relatively longer. In addition, we use special ceramic materials with good chemical stability such as alumina to prepare fragrance ceramic elements, which will not affect the smell of fragrance oil (water) and make the fragrance pure.
