Description

Technical Field

[0001] The present invention relates to the technical field of inorganic material processing, and particularly to a preparation method of an odor volatilization medium ceramic and a diffuser using the preparation method. Background Art

[0002] With the continuous improvement of people's environmental requirements, in some enclosed spaces, the air quality is very poor, such as in a car or a closed room. Therefore, for the purpose of improving the air environment, accessories such as aromatherapy and diffusers are becoming more and more popular among people. At present, most of the existing aromatherapy sticks use materials with a vent hole structure, such as activated carbon rods. These materials are easy to bend and have a high risk of catching fire at higher temperatures. Based on this, there are also some diffusers made of ceramics existing, but the ceramics fired at high temperatures have poor water absorption, which is not conducive to diffusion, and are mostly used as bases for loading, and still need to be used in combination with the above-mentioned aromatherapy sticks and other accessories. Summary of the Invention

[0003] In order to overcome the above technical defects, the purpose of the present invention is to provide a preparation method of an odor volatilization medium ceramic and a diffuser using the preparation method, which are used to overcome the problems that the existing diffusion structure is easy to bend and has a high fire risk.

[0012] Preferably, the obtained odor volatilization medium ceramic has plasticity.

[0013] Preferably, the content of the dolomite soil in the form of lumps and dense state rock lumps is 99%.

[0014] The present invention also provides a fragrance diffusing device, which uses the odor volatilization medium ceramic with a certain shape obtained by the preparation method described in any one of the above to have a high water absorption rate for fragrance diffusion.

[0015] Preferably, the molds for preparing the inner core and the outer shell are respectively in the shape of a heart-shaped cylinder for preparing the aromatherapy stick.

[0016] Preferably, the molds for preparing the inner core and the outer shell are used in combination to prepare diffusers with different shapes.

[0017] After adopting the above technical solutions, compared with the prior art, the following beneficial effects are achieved:

[0018] The present invention uses dolomite soil to be ground into powder and then mixed with water to form slurry.

[0025] Embodiment 1: The present invention discloses a preparation method of an odor volatilization medium ceramic. In this embodiment, mainly in order to address the problem that in existing diffusion devices (including but not limited to aroma sticks, diffusers, etc.), most of the structures for achieving the diffusion purpose use materials with a through-hole structure such as activated carbon rods and sponge rods. These materials are prone to bending and have a relatively high fire risk when the temperature is high, while existing ceramics have poor water absorption and cannot achieve the diffusion purpose. Therefore, to solve the above problems, a preparation method of a ceramic material is provided, so that the ceramic obtained based on this preparation method has high water absorption and can be used for diffusion or for preparing a diffusion device. Specifically, refer to Figure 1 , the preparation method includes the following steps:

[0026] S100: Obtain dolomite soil, crush it into powder by a ball mill, and mix it into a slurry at a ratio of 1:3 of soil to water;

[0027] In this embodiment, dolomite soil is used as the raw material for preparing the ceramic. Its mineral composition mainly consists of minerals such as kaolinite (Al4[Si4O10](OH)8), halloysite (Al4[Si4O10](OH)8·4H2O), hydromica, illite, montmorillonite (NaX(H2O)4{(Al2[Alx Si4-xO10](OH)2}), quartz, and feldspar; the content of the main mineral components reaches more than 90%. Preferably, the content of the dolomite soil in the form of soil lumps and dense rock lumps is 99%. That is, its appearance can be in the form of loose soil lumps and dense rock lumps depending on the origin. The dolomite soil used in this embodiment has the above appearance. After being rolled into powder, it is mixed into a slurry. Its density is 2.54 - 2.60 g / Cm3. The melting point is about 1785 degrees, white, delicate, and in a soft soil state. Thus, the ceramic obtained by subsequent firing has a relatively high melting point and is safer to use.

[0028] In this embodiment, a slurry is mixed in a ratio of 1:3 of water to soil. On the one hand, the subsequent prepared ceramic has better water absorption with this mixture. On the other hand, it has better plasticity. Plasticity is the property that wet soil can be molded into various shapes without breaking and can remain unchanged for a long time. Therefore, in order to facilitate subsequent shaping and firing, a slurry is formed with this mixture.

[0029] S200: Inject the slurry into the mold for preparing the core, stir and solidify it to obtain the medium core.

[0030] In the above steps, the ceramic fired in this embodiment includes two parts, the core and the shell, and two molds are used for preparation. Specifically, the two parts are prepared separately. On the one hand, it is convenient to prepare ceramics of different shapes to prepare diffuser devices of different shapes. On the other hand, it is convenient to operate and effectively improves the preparation efficiency. The above solidification can be achieved by static solidification or with the assistance of equipment. Specifically, as a supplement, the above injection of slurry, stirring and solidification can be completed manually or by machine automation.

[0031] S300: After obtaining part of the slurry and rolling it into a mud strip, use the mold for preparing the shell to process and shape it to obtain the medium shell.

[0032] In this embodiment, based on the above, the ceramic prepared by this solution is divided into two parts, molded by molds and then assembled and fired. Therefore, this step is the step of shaping the shell. Specifically, the mold for preparing the shell can be the same as or different from the aforementioned mold for preparing the core. For example, it can be made into a concentric cylindrical shape similar to the core, or a shape that radiates circumferentially to further increase the diffusing area and enhance the diffusing effect. Similar to the above, the above shaping process can be completed manually or by machine automation, and this step can be carried out synchronously or successively with the above S200.

[0033] S400: Place the medium core inside the medium shell, and inject mud into the gap to obtain a formed mold body.

[0034] Based on the above two steps, the core and the shell can be prepared separately. After preparing these two, mud needs to be injected into the gap to make the finally prepared ceramic (diffuser) solid, so as to utilize the prepared highly water-absorbent ceramic to achieve the effect of diffusing fragrance. Specifically, the above-mentioned formed mold body can have various shapes and can be adjusted according to the cooperation of the core mold and the shell mold.

[0035] S500: Cut and process the formed mold body and then load it into a kiln, and fire it at a low temperature of 1000 - 1150 °C to obtain a ceramic for odor volatilization medium.

[0036] In the above steps, cutting is convenient for mass production. It should also be noted that different from most existing porcelain that needs to be fired at a temperature of 1300 degrees, the ceramic fired at a high temperature has poor water absorption. In this embodiment, it is fired at a low temperature of 1000 - 1150 degrees with dolomite. Specifically, it is fired for about 7.5 hours. Specifically, the water absorption rate of the obtained ceramic for odor volatilization medium is not less than 12%, which is much higher than the water absorption rate of 0.2% for high-temperature firing, and the density is thinner, making it easier to emit the smell of aromatherapy. In addition, the obtained ceramic for odor volatilization medium has plasticity, that is, it can be molded into various shapes and can be maintained unchanged for a long time, with a strong plasticity of >153.6.

[0037] In this embodiment, dolomite is rolled into powder and mixed with water to form mud, and then the mud is injected into the core mold and the shell mold respectively to obtain the medium core and the medium shell respectively. Then, after assembling / cutting, it is fired at a low temperature of 1000 - 1150 °C for 7.5 hours to obtain a ceramic for odor volatilization medium with a water absorption rate of at least 12%, which is thus used to prepare a diffuser. The fired ceramic can solve the problems that the diffuser structure is easy to bend and has a relatively high fire risk. At the same time, this ceramic also has a high water absorption rate, which can achieve the effect of assisting odor volatilization.

[0038] Embodiment 2: This embodiment provides a diffuser. By using the preparation method of the above Embodiment 1, a ceramic for odor volatilization medium with a certain shape is obtained, which has a high water absorption rate for diffusing fragrance. As described in the above Embodiment 1, by using this preparation method, a ceramic for odor volatilization medium with a water absorption rate of not less than 12%, a density of 2.54 - 2.60 g / Cm3, and a melting point of about 1785 degrees can be prepared. By using different molds (the core mold and the shell mold), different-shaped ceramics for odor volatilization can be prepared as diffusers.

[0039] In an optionally implemented manner, the molds for preparing the inner core and the outer shell can be respectively in the shape of a heart-shaped cylinder for preparing the aroma diffuser stick, that is, a shape similar to the existing columnar aroma diffuser stick can be prepared, which can be combined with different aromas for diffusion in different scenarios. The aroma diffuser stick prepared in this embodiment is made of a ceramic material with high water absorption. While achieving the purpose of diffusion, it has a certain strength and a relatively high melting point, which can solve the problems that the diffusion structure is prone to bending and has a relatively high fire risk.

[0040] In another optionally implemented manner, the molds for preparing the inner core and the outer shell are used in cooperation to prepare diffusers of different shapes. As an example, it diffuses outward in the circumferential direction to enable the aroma liquid to drip in to achieve the diffusion effect. Not limited to this, as described above, the ceramics provided in this embodiment have high water absorption and good diffusion effect, and different shapes can meet the usage requirements in different scenarios.

[0041] It should be noted that the embodiments of the present invention have good implementability and do not impose any form of limitation on the present invention. Any person skilled in the art may use the technical content disclosed above to modify or transform it into equivalent effective embodiments. However, as long as it does not depart from the technical content of the technical solution of the present invention, any modification, equivalent change or modification made to the above embodiments based on the technical essence of the present invention still falls within the scope of the technical solution of the present invention.
