The detailed features and advantages of the present invention are set forth in the detailed description of the embodiments of the present invention. The objects and advantages associated with the present invention can be readily understood by those skilled in the art. The following examples further illustrate the aspects of the invention, but not any The views limit the scope of the invention.

Hereinafter, the first type heat generating element 10 of the present invention will be described. Please refer to Fig. 1. Fig. 1 is a schematic view showing a first type of heat generating member of the present invention.

The first type heat generating element 10 of the present invention comprises a heat generating composition 11, a heat insulating composition 12, a fragrance 13 and a gas permeable receiving bag 14.

The component of the heat generating composition 11 contains an oxidizing metal powder 111, a water-soluble salt 112, and water 113.

The oxidized metal powder 111 is a metal powder which can release heat when an oxidation reaction occurs. The composition of the oxidic metal powder 111 may be a group of iron, zinc, aluminum, magnesium, copper, and other metals which are oxidizable and exothermic. In order to make the oxidizable metal powder have better reactivity when an oxidation reaction occurs, the oxidized metal powder 111 may have an average particle diameter of 0.5 to 350 μm. The weight percentage of the oxidizing metal powder 111 in the contents of the gas permeable container 14 is 47 to 51%.

The water-soluble salt 112 can promote the oxidation reaction of the oxidized metal powder 111. The component of the water-soluble salt 112 may be a group consisting of sodium chloride (salt), potassium chloride, calcium chloride, and other salts which promote metal oxidation. The water-soluble salt 112 accounts for 4 to 6% by weight of the contents of the gas permeable containment bag 14.

The water 113 can be oxidized by the oxidizing metal powder 111 by the water-soluble salt 112. The water 113 accounts for 6 to 10% by weight of the contents of the gas permeable container 14.

The thermal insulation composition 12 comprises at least one porous material. The heat insulating composition 12 absorbs the heat released by the oxidizing metal powder 111 during the oxidation process, The heat is then slowly released, so that the first type heat generating element 10 can be maintained at a temperature higher than the ambient temperature for a long time. The weight percentage of the heat insulating composition 12 in the contents of the gas permeable container 14 is 30 to 38%.

The porous material in the heat insulating composition 12 has a large number of pores. These holes can hold a large amount of air to achieve the effect of blocking heat conduction. As a result, the speed at which heat is dissipated to the outside by the first type heat generating member 10 is slowed down. In order to achieve a better thermal insulation effect, the pore diameter of the porous material is preferably from 0.6 to 50 nanometers (nm), and the proportion of the mesopores in the pores is preferably from 40 to 60%. The composition of the porous material may be a group of activated carbon, vermiculite, and other porous materials that can accommodate a large amount of air. The activated carbon has a better absorption effect on the short-wavelength infrared rays emitted when the oxidized metal powder 111 is oxidized. The vermiculite has a better absorption effect on the long-wavelength infrared rays emitted when the oxidized metal powder 111 is oxidized. When the activated carbon and the vermiculite each account for 50% by weight of the porous material contained in the heat insulating material 12, the porous material has a preferable heat insulating effect. The average particle size of the activated carbon that can achieve the thermal insulation effect is 37 to 200 micrometers (μm). In order to obtain a better thermal insulation effect, the activated carbon may have an average particle diameter of 50 to 70 micrometers (μm). The average particle size of the vermiculite which can achieve the heat preservation effect is 300 to 1000 micrometers (μm). In order to obtain a better thermal insulation effect, the average particle diameter of the vermiculite may be 400 to 500 micrometers (μm).

The fragrance 13 provides a pleasant or relaxing odor of the first type heat generating member 10 to alleviate the discomfort caused by the odor of the oxidizing metal powder 111. The type of fragrance may be a group of natural flavors and synthetic flavors. The form of the fragrance 13 can be solid or liquid. For example, the form of the fragrance 13 can be a chemical combination Into flavor powder, spice plant powder, natural plant essential oil, Chinese herbal medicine essential oil or chemical synthetic essential oil. The volatilization temperature of the fragrance 13 falls within the heating temperature range of the heat generating member (40 to 70 ° C), and has a better aroma diffusing effect. The percentage by weight of the fragrance 13 in the contents of the gas permeable containment bag 14 is from 1 to 5%.

The gas permeable storage bag 14 covers a mixture of the heat generating composition 11, the heat insulating composition 12, and the fragrance 13 to constitute the first heat generating element 10. The heat generated by the heat generating composition 11 and the aroma generated by the volatilization of the fragrance 13 are radiated to the outside of the first type heat generating member 10 through the fine perforations of the surface of the gas permeable receiving bag. The material of the gas permeable bag can be a group of natural fibers and rayon.

It is to be noted that in the mixture of the heat generating composition 11, the heat insulating composition 12 and the perfume 13, the perfume 13 is present in a mixture in such a manner as to adhere to the surface of the carrier, combine with the matrix to form particles or coat the carrier. For example, the fragrance 13 is adsorbed in the pores of the porous material, mixed with the substrate, and then kneaded into a perfume ball, or is present in the mixture in the form of being coated in a dropping pill or a capsule. When the fragrance 13 is present in the mixture in the form of a perfume ball or a dropping pill, the particle size of the perfume ball or the dropping pill is preferably 3 to 8 nm, and more preferably the particle size is 4 to 5 nm.

Next, the second type heat generating element 20 of the present invention will be described. Please refer to Fig. 2. Fig. 2 is a schematic view showing a second type of heat generating member of the present invention. The second type heat generating element 20 has a similar structure to the first type heat generating element 10, and only the differences will be described herein, and the rest will not be described again.

The second type heat generating element 20 includes a heat generating composition 21, a heat insulating composition 22, a fragrance 23, and a gas permeable receiving bag 24. In addition to this, the second type The heat member 20 further includes a water absorbing composition 25. Before the second type heat generating element 20 is not used, the water absorbing composition 25 can adsorb excess moisture around the second type heat generating element 20 to prevent the oxidized metal powder 211 in the second type heat generating element 20 from coming into contact with moisture. The oxidation reaction begins early. In this way, when the second type heat generating element 20 is used, it is possible to avoid that the oxidizing metal powder 211 has completed the oxidation reaction and cannot continue the oxidation reaction to release heat, so that the heat generation temperature of the second type heat generating element 20 cannot reach the predetermined temperature. temperature. Further, during use of the second type heat generating element 20, the heat released by the oxidation of the oxidizing metal powder 211 heats the water absorbing composition 25, and the moisture adsorbed in the water absorbing composition 25 adsorbing the moisture state is slowly volatilized and desorbed. The water-absorptive composition 25 further returns the water-absorptive composition 25 to a dry state in which no moisture is adsorbed. Simultaneously, the moisture adsorbed in the water-absorptive composition 25 is slowly released and brought into contact with the oxidizing metal powder 211 to assist in controlling the oxidative metal powder 211 to slowly oxidize and release heat. In this way, the second type heat generating member in use does not rapidly rise due to the oxidative exothermic reaction, so that the second type heat generating member has a stable heat releasing effect. When the second type heat generating element 20 is used, the water absorbing composition 25 in the second type heat generating element 20 is in a dry state. As a result, the second type heat generating element 20 after use is converted into a dehumidifying article that can absorb moisture in the air and has a second use.

In addition, when the water-soluble salts 112 and 212 having better adsorptivity to water gas are used in the first type heat generating element 10 and the second type heat generating element 20, the water-soluble salt having a better adsorption property to moisture is provided. 212 can also achieve the effect similar to that produced by the water-absorbing composition 25. For example, the water-soluble salts 112, 212 which have better adsorptivity to moisture are calcium chloride.

The manufacturing method of the first type heat generating element 10 of the present invention will be described below. Referring to FIGS. 3 to 5, FIG. 3 is a flow chart showing the fabrication of the first type heat generating element according to the first embodiment of the present invention. Fig. 4 is a flow chart showing the fabrication of the first type heat generating element of the second embodiment of the present invention. Fig. 5 is a flow chart showing the manufacture of the first type heat generating element according to the third embodiment of the present invention.

The manufacturing process of the first type heat generating element according to the first embodiment of the present invention is as shown in Fig. 3.

First, an oxidizing metal powder, a water-soluble salt, and water are mixed to form a heat generating composition (S101).

Specifically, an oxidizing metal powder, 4 to 6% of a water-soluble salt, and 6 to 10% of water, which are 47 to 51% by weight of the contents of the gas permeable container, are uniformly mixed to form a heat generating composition. It is important to note that the mixing speed and force must be paid attention to during mixing to avoid oxidation of the oxidized metal powder and start to exotherm. In other words, the oxidizing metal powder and the water-soluble salt are uniformly mixed with water without oxidizing the oxidized metal powder. In the following production process, attention should also be paid to the mixing-related steps to avoid oxidation of the oxidized metal powder.

Next, the heat generating composition, the heat insulating composition, and the fragrance are mixed (S102).

Specifically, the heat-generating composition and the heat-insulating composition of 30 to 38% by weight of the contents of the gas-permeable container are uniformly mixed with 1 to 5% of the flavor. The fragrance is mixed with the heat generating composition and the heat insulating composition in a form of being combined with a matrix to form particles or coated in a carrier.

Finally, the mixed heat generating composition, the heat insulating composition, and the flavor are accommodated in the gas permeable storage bag (S103).

Specifically, the mixed heat-generating composition, the heat-insulating composition, and the fragrance are placed in a gas permeable storage bag. The opening of the gas permeable receiving bag is heat-sealed by means of hot pressing to complete the fabrication of the first type of heat generating member.

The manufacturing process of the first type heat generating element according to the second embodiment of the present invention is as shown in Fig. 4.

First, an oxidizing metal powder, a water-soluble salt, and water are mixed to form a heat generating composition (S201). Since this step (S201) is similar to the step (S101) of the first type heat generating element manufacturing flow of the first embodiment, the same points will not be described herein.

Next, the composition and the fragrance are premixed, and the heat retaining composition adsorbs the fragrance (S202).

In detail, a liquid fragrance is sprayed on the surface of the heat-insulating composition so that the liquid fragrance is adsorbed by the heat-insulating composition. Further, when the liquid fragrance is sprayed on the porous material contained in the heat insulating composition, the liquid fragrance is adsorbed by the pores of the porous material to be filled in the pores of the porous material.

Since the fragrance is present in the form of being filled in the pores of the heat-insulating composition (porous material), the area of the fragrance in contact with the outside air is reduced, and the speed at which the fragrance is volatilized into the air is lowered. Therefore, when the heat generating member is not used, the fragrance is less likely to be volatilized, and the heat generating member gradually loses the fragrance in an unused state. When the heat generating member is used, the heat generated by the heat generating member accelerates the volatilization of the fragrance to release the aroma. At this time, the pores of the porous material are restricted to the area where the fragrance is in contact with the outside air, and the fragrance is not The method is disposable by a large amount of volatilization in the pores of the porous material. In this way, the volatilized fragrance slowly leaves the pores and enters the air, so that the heat generating member can slowly release the aroma during the heat generation.

Next, the heat insulating composition to which the fragrance is adsorbed and the heat generating composition are mixed (S203).

Specifically, the heat-insulating composition and the heat-generating composition in which the fragrance is adsorbed are mixed while avoiding an oxidation reaction of the oxidized metal powder contained in the heat-generating composition.

Finally, the mixed heat generating composition, the heat insulating composition, and the flavor are accommodated in the gas permeable storage bag (S204). Since this step (S204) is similar to the step (S104) of the first type heat generating part manufacturing flow of the first embodiment, the same points will not be described herein.

The manufacturing process of the first type heat generating element according to the third embodiment of the present invention is as shown in Fig. 5.

First, an oxidizing metal powder, a water-soluble salt, and water are mixed to form a heat generating composition (S301). Since this step (S301) is similar to the step (S101) of the first type heat generating element manufacturing flow of the first embodiment, the same points will not be described herein.

Next, the heat insulating composition is subjected to microwave heat treatment (S302).

Specifically, after the heat insulating composition is placed in water, the heat insulating composition and water are heated by microwave, and the heat insulating composition is heated in water of 80 to 100 ° C for 20 to 40 minutes. Next, the insulation composition was taken out of the water and completely dried.

The porous material contained in the heat insulating composition is subjected to a microwave hot water bath During the process, impurities packed in the pores or attached to the pore walls are dissolved by the hot water or taken out of the pores. As a result, the total surface area and total pore volume of the porous material contained in the heat insulating composition are improved. Since the total amount of air having a low heat transfer coefficient coated in the pores is increased, the rate of heat loss is lowered, and the heat insulating effect of the heat insulating composition is improved.

Next, the composition and the fragrance are premixed, and the heat retaining composition adsorbs the fragrance (S303). Since this step (S303) is similar to the step (S202) of the first type heat generating element manufacturing flow of the second embodiment, the same points will not be described herein.

Next, the heat-insulating composition to which the fragrance is adsorbed and the heat-generating composition are mixed (S304). Since this step (S304) is similar to the step (S203) of the first type heat generating element manufacturing flow of the second embodiment, the same points will not be described herein.

Finally, the mixed heat generating composition, the heat insulating composition, and the flavor are accommodated in the gas permeable storage bag (S305). Since this step (S305) is similar to the step (S103) of the first type heat generating element manufacturing flow of the first embodiment, the same points will not be described herein.

Next, a flow of manufacturing a second type heat generating member according to a fourth embodiment of the present invention will be described. Fig. 6 is a flow chart showing the fabrication of a second type heat generating member according to a fourth embodiment of the present invention.

First, an oxidizing metal powder, a water-soluble salt, and water are mixed to form a heat generating composition (S401). Since this step (S401) is similar to the step (S101) of the first type heat generating part manufacturing flow of the first embodiment, the same points will not be described herein.

Next, the heat generating composition, the heat insulating composition and the fragrance are mixed (S402). Due to the steps of this step (S402) and the first type heat generating part manufacturing process of the first embodiment (S102) is similar, and the same points will not be described here.

Next, the water-absorptive polymer material and the mixed heat-generating composition and the heat-insulating composition are mixed with the fragrance (S403).

In detail, the water-absorbing polymer material is a hydrogel which is a functional polymer material capable of absorbing and retaining a liquid much larger than its own mass. In the process of mixing, the water-absorbing polymer can adsorb the water vapor in the mixture, and the oxidizing metal powder can be prevented from starting the oxidation reaction early due to contact with the water gas.

Finally, the water-absorbent polymer material, the heat-generating composition, the heat-insulating composition, and the flavor after mixing are accommodated in the gas permeable storage bag (S404).

Specifically, the water-absorbent polymer material, the heat-generating composition, the heat-insulating composition, and the fragrance after mixing are placed in a gas permeable storage bag. The opening of the gas permeable receiving bag is heat-sealed by means of hot pressing to complete the production of the second type heat generating member.

Hereinafter, the first type heat generating element and the second type heat generating element disclosed in the present invention are described by several embodiments and comparative examples of the present invention, and experimental tests are performed to compare the difference in properties.

Finally, the mixed heat-generating composition, 8 g of activated carbon, 8 g of vermiculite, and 2 g of essential oil dropping pills were placed in a gas permeable receiving bag made of non-woven fabric. The opening sealing of the gas permeable receiving bag is performed by hot pressing to complete the preparation of the first type heat generating member.

Next, 2 grams of essential oil was sprayed onto the surface of the finely microwaved activated carbon.

Finally, the opening seal of the gas permeable receiving bag is performed by hot pressing to complete the preparation of the first type heat generating member.

Comparative example one

The first comparative example is a general heating element (warm pack) sold on the market. Generally, the heating element is not added with a fragrance and a water-absorbing polymer, and the heat-insulating composition in the general heating element is also not subjected to microwave treatment.

Next, the first type heat generating members of the first to third embodiments and the heat generating members of the first example were subjected to temperature measurement every hour and the measurement results were compared.

Referring to Fig. 7, Fig. 7 is a temperature versus time chart of the heat generating element of the first embodiment of the present invention and the heat generating element of the first comparative example. As can be seen from Fig. 7, the heat-generating member to which the essential oil dropping pellet was added in the first embodiment had a heat insulating effect superior to that of the heating member of Comparative Example 1. The heat generating element of the first embodiment and the heat generating element of the first comparative example have substantially the same temperature at the first hour to the tenth hour from the start of heat generation. However, after the 10th hour, the temperature of the heat generating element of the first embodiment can be maintained at about 5 ° C higher than the temperature of the heat generating element of Comparative Example 1, especially at the 12th hour to the 16th hour, the temperature difference between the two Can reach a gap of more than 5 °C.

Referring to Fig. 8, Fig. 8 is a temperature versus time chart of the heat generating element of the second embodiment of the present invention and the heat generating element of the first comparative example. As can be seen from Fig. 8, the second embodiment The heat-generating member adsorbing the activated carbon of the essential oil has a heat insulating effect superior to that of the heat-generating member of Comparative Example 1. The temperature of the heat generating element of the second embodiment and the heat generating element of the first comparative example were substantially the same at the first hour to the tenth hour from the start of the heat generation. However, after the 10th hour, the temperature of the heat generating element of the first embodiment can be maintained at about 3 ° C higher than the temperature of the heat generating element of Comparative Example 1.

Referring to FIG. 9, FIG. 9 is a temperature versus time diagram of the heat generating element according to the second embodiment and the second embodiment of the present invention and the heat generating element of the first comparative example. As can be seen from Fig. 9, the heat-generating member using the active carbon and the calcium chloride sprayed with the essential oil in one of the second embodiment and the second embodiment has the heat insulating effect superior to that of the heat-generating member of the first comparative example. After the third hour from the start of the heat generation, the temperature of the heat generating element of one of the second embodiment and the second embodiment can be maintained at about 5 ° C higher than the temperature of the heat generating element of the first comparative example.

Referring to Fig. 10, Fig. 10 is a temperature versus time diagram of the heat generating element of the third embodiment of the present invention and the heat generating element of the first comparative example. As can be seen from Fig. 10, the heat-generating member using the microwave-treated activated carbon of Example 3 has a heat insulating effect superior to that of the heat-generating member of Comparative Example 1. Since the microwave-treated activated carbon has a high total pore volume, it can accommodate a large amount of air having a low heat transfer coefficient, so that the heat energy is dissipated outward from the heat generating member at a slower speed and has a better heat insulating effect. The heat-generating member of the third embodiment can be maintained at a temperature of 5 ° C to 10 ° C higher than the temperature of the heat-generating member of Comparative Example 1 from the start of the heat generation to the start of the heat generation.

In Example 3, the conclusion that the microwave treated activated carbon has a higher total surface area and total pore volume can be confirmed by Figure 11. Figure 11 is a plot of pore volume and pore size distribution of activated carbon before and after microwave treatment. Will be micro Before the wave treatment, the activated carbon after microwave treatment was physically adsorbed at -196 ° C, and then measured and calculated. The surface area of the activated carbon treated by microwave was increased by 16%, the pore volume was increased by 18%, and the mesopore ratio was increased by 6%.

Next, the temperature measurement of the second type heat generating element of the fourth embodiment and the heat generating element of the first example was performed every hour and the measurement results were compared.

Referring to Fig. 12, Fig. 12 is a temperature versus time chart of the heat generating element of the fourth embodiment of the present invention and the heat generating element of the first comparative example. As can be seen from Fig. 12, the heat-generating member to which the water-absorbent polymer of the fourth embodiment is added has a heat insulating effect superior to that of the heat-generating member of the first comparative example. The temperature of the heat generating element of the fourth embodiment can be maintained at about 10 ° C higher than the temperature of the heat generating element of Comparative Example 1 from the 8th hour to the 16th hour after the start of the heat generation.

Finally, the first type of heat-generating member of the second embodiment was subjected to an aroma durability test.

The test method is to take out the activated carbon in the first type heat generating element of the second embodiment in the first hour and the 16th hour after the start of the fever. Next, the activated carbon is separately placed in hot water to dissolve the essential oil adsorbed in the pores of the activated carbon. Finally, the dissolved essential oil was subjected to ultraviolet-visible spectroscopy. Since the essential oil contains an aromatic compound having an absorption wavelength of 220 to 260 nm, the amount of the fragrance remaining in the heat-generating member can be obtained based on the residual aromatic compound content, thereby judging whether or not the heat-generating member can continue to release the aroma.

Referring to FIG. 13, FIG. 13 is a UV-visible spectrum of the essential oil adsorbed by the activated carbon in the heat generating element according to the second embodiment of the present invention. After the heating element starts to heat for 16 hours, the amount of essential oil in the heating element still remains. The original 87% or so, so the heat-generating parts can continue to emit aroma. The peak of the absorption peak at a wavelength of 240 to 250 nm decreased by about 13% from the height of the absorption peak at the 16th hour after the start of fever. It is indicated that during the process of heating of the heating element, the essential oil is slowly volatilized and released into the outside air, so that the amount of essential oil in the heating element is decreased.

According to the above-described scented heat generating member and the method of manufacturing the same, a specific heat generating component is used and a heat generating member is manufactured by a specific manufacturing method. In this way, the essential oil contained in the heat generating member is volatilized by heat to release the aroma, so that the user's discomfort to the smell of the heat generating member is alleviated. Adding the water-absorbing composition to the heat-generating component or using the microwave-treated heat insulating material increases the heat-insulating effect of the heat-generating component, thereby slowing down the temperature with time. The heat-generating member is made of a water-soluble salt having water absorbability or an additional water-absorbent composition, so that the heat-generating member after use has a second use which can be reused as a dehumidification pack.

Although the embodiments of the present invention are disclosed above, it is not intended to limit the present invention, and those skilled in the art, regardless of the spirit and scope of the present invention, the shapes, structures, and features described in the scope of the present application. And the spirit of the invention is subject to change. Therefore, the scope of patent protection of the present invention is subject to the scope of the patent application attached to the specification.
