Description

Technical Field

[0001] The present invention relates to the technical field of aerosol supply, and in particular, to an aerosol supply system and method. Background Art

[0002] In electronic aerosol supply systems such as heat-not-burn (THP or HNB), a large amount of heat is generated during use, resulting in an excessively high surface temperature of the system. Generally, the safe temperature of the system surface is considered to be within 45°C, and the product quality limit requires that the high temperature should not exceed 48°C. However, for such aerosol supply systems of heat-not-burn (THP or HNB), the tobacco consumable must be heated to a certain temperature, such as 350°C, to obtain the best flavor. Therefore, it is necessary to remind the user when to smoke so that the user can experience the best flavor.

[0003] In order to remind the customer of the appropriate timing of puffing, or not to over-smoke, or to prevent high-temperature scalding, etc., some UI elements are usually designed on the aerosol supply system. Common UI designs include integrating a vibration motor or an indicator light on the aerosol supply system, but their operations all rely on temperature calculation or temperature sensors, and a microcontroller (MCU) circuit is required to determine whether the temperature is too high. Thus, the following defects exist:

[0004] 1) Both the vibration motor and the indicator light consume a certain amount of electrical energy, increasing the energy consumption burden of the battery component of the aerosol supply system;

[0005] 2) For the temperature indication of the system surface, the temperature sensor cannot accurately reflect the exact value of the system surface temperature. Because it is not installed on the surface of the system, in fact, the temperature of the outer surface is estimated by collecting the temperature inside the system.

[0006] Therefore, there is an urgent need to propose a new aerosol supply system to solve one or more of the above problems. Summary of the Invention

[0007] The present invention aims to solve at least one of the technical problems existing in the prior art. For this purpose, the present invention proposes an aerosol supply system and method to solve the technical problem of how to achieve the temperature indication of the aerosol supply system without consuming additional electrical energy.

[0009] A thermochromic module, at least including a thermochromic material, the thermochromic module is disposed on the housing of the system and has a surface visible to the user, and is configured to change color when sensing that the system reaches the color-changing temperature.

[0010] Since the thermochromic module is made of thermochromic material, no additional electrical energy of the battery assembly of the aerosol supply system is consumed during the process of indicating the surface temperature or the heating area temperature of the aerosol supply system.

[0012] By setting the thermochromic module to change color or display a preset pattern when it senses that the aerosol supply system reaches the color-changing temperature, the purpose of temperature reminder or indication can be achieved, and at the same time, an interesting coating effect can be achieved, increasing the aesthetic degree of the system and improving the fun of users using the product.

[0013] In one technical solution of the above aerosol supply system, the thermochromic module includes a substrate and a preset pattern or a second preset color provided on the substrate, the thermochromic material covers the preset pattern or the second preset color, and the thermochromic module shows a transparent color when the system reaches the color-changing temperature to display the preset pattern or the second preset color, otherwise it shows a non-transparent color to block the preset pattern or the second preset color.

[0014] In one technical solution of the above aerosol supply system, the substrate is integrally formed with the housing of the system or the substrate is provided on the housing of the system.

[0027] It can be understood that the costs of different temperature-sensitive color-changing materials may be different, and using diversified temperature-sensitive color-changing materials to indicate the temperature level may increase the production cost. Based on this, by setting the heat insulation member, the temperatures sensed by the temperature-sensitive color-changing units prepared with the same material are different, so as to achieve the purpose of indicating different temperatures.

[0079] An aerosol-generating material is a material that is capable of generating an aerosol when heated, irradiated, or energized in any other way, for example. The aerosol-generating material can be, for example, in solid, liquid, or gel form, and it can contain or can not contain active substances and / or flavorings.

[0084] A consumable is an article that includes or consists of an aerosol - forming material, with part or all of the aerosol - forming material intended to be consumed by a user during use. The consumable can include one or more other components, such as an aerosol - forming material storage area, an aerosol - forming material delivery component, an aerosol - forming area, a housing, a wrapper, a mouthpiece, a filter, and / or an aerosol modifier. The consumable can also include an aerosol generator, such as a heater, which releases heat during use to cause the aerosol - forming material to form an aerosol. The heater can, for example, include a combustible material, a material that can be heated by electrical conduction, or a susceptor.

[0085] A susceptor is a material that can be heated by penetration with a varying magnetic field (such as an alternating magnetic field). The susceptor can be a conductive material such that penetration by the varying magnetic field causes inductive heating of the material. The heating material can be a magnetic material such that penetration by the varying magnetic field causes hysteresis heating of the material. The susceptor can be both conductive and magnetic such that the susceptor can be heated by both heating mechanisms. In this document, a device configured to generate a varying magnetic field is referred to as a magnetic - field generator.

[0086] An aerosol modifier is a substance that is typically located downstream of the aerosol - forming area and is configured to modify the generated aerosol, for example, by changing the taste, flavor, acidity, or another characteristic of the aerosol. The aerosol modifier can be provided in an aerosol - modifier release component that is operable to selectively release the aerosol modifier. For example, the aerosol modifier can be an additive or an adsorbent. For example, the aerosol modifier can include one or more of a flavoring, a coloring agent, water, and a carbon adsorbent. For example, the aerosol modifier can be a solid, a liquid, or a gel. The aerosol modifier can be in the form of a powder, a wire, or a granule. The aerosol modifier can be free of filter material.

[0087] An aerosol generator is a device configured to cause an aerosol to be formed from an aerosol - forming material. In some embodiments, the aerosol generator is a heater that is configured to subject the aerosol - forming material to thermal energy in order to release one or more volatiles from the aerosol - forming material to form an aerosol. In some embodiments, the aerosol generator is configured to cause an aerosol to be formed from the aerosol - forming material without heating. For example, the aerosol generator can be configured to subject the aerosol - forming material to one or more of vibration, increased pressure, or electrostatic energy.

[0088] The present disclosure relates to aerosol delivery systems (which may also be referred to as vapor delivery systems), such as atomizers or electronic cigarettes. In the following description, the term "electronic cigarette" or "e-cigarette" may sometimes be used, but it will be understood that this term may be used interchangeably with aerosol delivery systems / devices and electronic aerosol delivery systems / devices. Additionally, as is common in the art, the terms "aerosol" and "vapor" and related terms such as "evaporation", "atomization", and "aerosolization" are generally used interchangeably.

[0089] Aerosol delivery systems (e-cigarettes) typically (although not always) include modular components, which include a reusable device portion and a replaceable (disposable / consumable) cartridge component. Generally, the replaceable cartridge component will include aerosol-generating material and an evaporator (which may be collectively referred to as an "atomizer"), and the reusable device portion will include a power source (e.g., a rechargeable power source) and control circuitry. It will be understood that these different portions may include additional elements depending on the function. For example, the reusable device portion will typically include a user interface for receiving user input and displaying operational status characteristics, and the replaceable cartridge device portion includes a temperature sensor for assisting in controlling temperature in some cases. The cartridge is electrically and mechanically coupled to the control unit for use, for example, using threads, bayonet, or magnetic coupling with appropriately arranged electrical contacts. When the aerosol-generating material in the cartridge is depleted, or the user wishes to switch to a different cartridge with a different aerosol-generating material, the cartridge can be removed from the reusable component, and a replacement cartridge can be attached in its place. Systems and devices that conform to this type of two-piece modular configuration are generally referred to as two-piece systems / devices.

[0090] Electronic cigarettes generally have a generally elongated shape. To provide a specific example, some embodiments of the present disclosure will be considered to include such a generally elongated two-piece system with a disposable cartridge. However, it will be understood that the basic principles described herein can equally apply to different configurations, such as single-piece systems or modular systems including more than two components, refillable devices and single-use disposables, and other overall shapes, such as so-called pod-mode high-performance devices that are generally box-shaped. More generally, it will be understood that certain embodiments of the present disclosure are based on aerosol delivery systems that are operationally configured to provide functions in accordance with the principles described herein, and the construction aspects of systems configured to provide the functions of certain embodiments of the present disclosure are not of primary importance.

[0091] As described in the background art, in order to remind customers of the appropriate timing of puffing, or not to over-smoke, or to prevent high-temperature burns, etc., the conventional method is to integrate a vibration motor or an indicator light, etc. on the aerosol supply system. However, their operations all rely on temperature calculation or temperature sensors, and a microcontroller circuit is required to determine whether the temperature is too high. On the one hand, both of the above two methods consume a certain amount of electrical energy, increasing the energy consumption burden on the battery component of the aerosol supply system; on the other hand, since the temperature sensor is not installed on the surface of the system, the temperature of the outer surface is actually estimated through the temperature acquisition inside the system, so it cannot accurately reflect the surface temperature of the system. Based on this, the present invention proposes an aerosol supply system that realizes temperature indication without consuming additional electrical energy.

[0092] It can be understood that the specific type of the aerosol supply system is not limited in the embodiments of the present application, and it includes atomizing e-cigarettes, heat-not-burn systems, etc. The following will take the heat-not-burn system as an example to illustrate the solution of the present application. As described above, such an aerosol supply system of the heat-not-burn system can generate aerosol from the aerosol-forming material by applying heat to the aerosol-forming material rather than burning the aerosol-forming material. The aerosol-forming material can exist as a component of the aerosol-forming article, where the aerosol-forming article is physically separated from the aerosol supply system. Such an aerosol-forming article can be received in the heating chamber of the aerosol supply system. In use, the aerosol supply system can provide power so that heat can be transferred from the heat source to the aerosol-forming material. During the use of such an aerosol supply system, volatile compounds are released from the aerosol-forming material through heat transfer from the heat source and entrained in the air drawn through the aerosol supply system. When the released compounds cool, they condense to form the aerosol inhaled by the consumer.

[0093] Figure 1 is a schematic structural diagram of an aerosol supply system according to an embodiment of the present application. Referring to Figure 1 as shown, the aerosol supply system generally includes: a housing 100, a thermochromic module 200, and a protection module (not shown in the figure). Among them, the thermochromic module 200 is disposed on the housing 100 and has a thermochromic module 200 with a surface visible to the user, and the protection module covers the display surface of the thermochromic module 200.

[0094] It should be noted that Figure 1It is a schematic diagram of an example of an aerosol supply system, and other components or structures of the aerosol supply system arranged in the shell 100 are omitted, such as a heating chamber (not shown in the figure) formed in the shell 100, which is configured to receive an aerosol generating product; a heater (not shown in the figure) arranged in the shell, which is configured to heat the aerosol generating product to supply an aerosol; a control module (not shown in the figure) arranged in the shell, which is configured to be associated with the heater so as to control the heater to heat the aerosol generating product to generate an aerosol; a battery assembly (not shown in the figure), which is configured to provide electrical energy to the heater, and they are not described one by one here.

[0095] In the embodiment of the present application, the thermochromic module 200 is configured to be disposed on the housing 100 and has a surface visible to the user. The thermochromic module 200 contains a thermochromic material, and changes color when the thermochromic module 200 senses that the aerosol supply system reaches the color change temperature. It should be noted here that in the embodiment of the present application, the thermochromic module 200 actually senses the temperature of the surface of the aerosol supply system. On the one hand, the surface temperature of the system can be reminded by changing color to prevent high temperature burns. On the other hand. The color change temperature value or the specific components of the thermochromic material can also be adjusted according to the relationship between the temperature actually sensed by the thermochromic module 200 and the actual temperature of the heating area, so that the temperature actually sensed by the thermochromic module 200 (i.e., the color change temperature) can represent the actual temperature of the heating area, thereby realizing the right time to remind the customer to inhale, so that the user can experience the best flavor.

[0096] Due to the safety of the human body, in order to prevent users from being burned by high temperatures, the safe temperature of the shell surface of the aerosol supply system is usually set within 45°C. For aerosol supply systems such as heat-not-burn (THP or HNB), tobacco consumables must be heated to a certain temperature, such as 350°C, to obtain the best flavor. Therefore, as a preferred embodiment, in the embodiment of the present application, the color change temperature range of the thermochromic material is 45-350°C. In addition, for safety reasons, to avoid high temperature burns to users, when the thermochromic module 200 is used to indicate the temperature of the heating area, the color change temperature can be determined based on the relationship between the temperature of the shell surface and the actual temperature of the heating area. The specific process will not be repeated here.

[0097] In the embodiment of the present application, there is no specific limitation on the position of the thermochromic module 200 on the housing 100, and it only needs to have a surface visible to the user. In one implementation of the present application, the thermochromic module 200 can be attached to any position on the surface of the housing 100, preferably to a position on the surface of the housing 100 corresponding to the heating area of ​​the aerosol supply system.

[0098] In another embodiment of the present application, the thermochromic module 200 is integrally formed with the housing 100. For example, the thermochromic module 200 forms a part of the housing 100, or the thermochromic module 200 forms the entire housing 100.

[0099] In another embodiment of the present application, the thermochromic module 200 is embedded in the housing 100, that is, the thermochromic module 200 and the housing 100 form two parts, and the thermochromic module 200 is embedded in the housing 100.

[0100] It can be understood that in some aerosol supply systems, there is also a warning light provided on the housing 100. The warning light can be provided on the housing in the form of a button. The warning light is usually configured to give a reminder about the battery level, etc. In one embodiment of the present application, the thermochromic module 200 is attached to the surface of the button of the warning light on the housing 100. In another embodiment of the present application, the thermochromic module 200 is embedded in the button of the warning light on the housing of the system.

[0101] Since the thermochromic module 200 can cover the whole or part of the housing of the aerosol supply system, it can also be used to create an interesting coating effect, so that the aerosol supply system can have two or more skin-like appearances.

[0102] Since the thermochromic pigment can achieve color changes from "colored to colorless" or from "colored to colored" or from "colorless to colored" states. Based on this, in a specific embodiment, in the embodiment of the present application, the thermochromic module 200 can give a temperature reminder by changing its color. As a preferred embodiment, the thermochromic material of the thermochromic module 200 can be configured to change to a first preset color when it senses that the aerosol supply system reaches the color-changing temperature, where the first preset color is any non-transparent color or a transparent color. The non-transparent color can be any one of red, yellow, blue, etc., and will not be enumerated one by one here. It can be understood that when the first preset color is a non-transparent color, the initial color of the thermochromic material of the thermochromic module 200 should be a non-transparent color different from the first preset color or a transparent color. When it senses that the aerosol supply system reaches the color-changing temperature, the thermochromic material changes from the initial color to the first preset color to achieve the purpose of temperature reminder. When the first preset color is a transparent color, the initial color of the thermochromic material of the thermochromic module 200 can be any non-transparent color. When it senses that the aerosol supply system reaches the color-changing temperature, the thermochromic material changes from any non-transparent color to a transparent color to achieve the purpose of temperature reminder.

[0103] In another specific embodiment, the temperature-sensitive color-changing module 200 can provide temperature prompts by displaying a pattern. As a preferred implementation, the temperature-sensitive color-changing module 200 can be configured to display a preset pattern when it senses that the aerosol supply system reaches the color-changing temperature. The preset pattern can be any pattern, and no specific limitation is made here. Exemplarily, the initial state of the temperature-sensitive color-changing material of the temperature-sensitive color-changing module 200 can be any non-transparent color. A preset pattern is covered under the temperature-sensitive color-changing material. When it senses that the aerosol supply system reaches the color-changing temperature, the temperature-sensitive color-changing material changes from the color in the initial state to a transparent color to display the preset pattern for the purpose of temperature prompting; or, the preset pattern is drawn by the temperature-sensitive color-changing material, and its initial state is transparent. When it senses that the aerosol supply system reaches the color-changing temperature, the temperature-sensitive color-changing material changes from the transparent color in the initial state to any non-transparent color to display the preset pattern for the purpose of temperature prompting. In addition to the above display methods, the temperature-sensitive color-changing module 200 in the embodiments of the present application can also be configured such that the initial color of the temperature-sensitive color-changing material is transparent, and a preset pattern is covered under the temperature-sensitive color-changing material, that is, the preset pattern can be displayed in the initial state. When it senses that the aerosol supply system reaches the color-changing temperature, the temperature-sensitive color-changing material changes from the transparent color in the initial state to any non-transparent color to cover the preset pattern for the purpose of temperature prompting.

[0104] As a preferred implementation, in the embodiments of the present application, the temperature-sensitive color-changing module 200 can be composed of a substrate and a preset pattern or a second preset color provided on the substrate. During specific implementation, the temperature-sensitive color-changing material covers the preset pattern or the second preset color. The initial state of the temperature-sensitive color-changing material can be any non-transparent color (such as black, etc.) to block the preset pattern or the second preset color. When it senses that the aerosol supply system reaches the color-changing temperature, the temperature-sensitive color-changing material changes from the non-transparent color in the initial state to a transparent color to display the preset pattern or the second preset color, thereby achieving the purpose of temperature prompting. Herein, the second preset color is any other non-transparent color except the color in the initial state of the temperature-sensitive color-changing material. It can be understood that the second preset color can be coated on the substrate or the color inherent in the substrate itself, and no specific limitation is made here.

[0105] Preferably, the preset pattern can be set as a temperature value to intuitively remind the user of the temperature reached on the surface of the housing or the heating area of the current aerosol supply system.

[0106] In a specific embodiment, the substrate is integrally formed with the housing 100 of the aerosol supply system, that is, the substrate forms part or the whole of the housing 100. In another specific embodiment, the substrate is a separate component, which is disposed on the housing 100 of the aerosol supply system. It should be noted that the embodiments of the present application do not specifically limit the connection manner between the substrate and the housing 100, and the user can select according to actual needs.

[0107] Referring to Figure 2 As shown, as a preferred embodiment, in the embodiments of the present application, the thermochromic module 200 may be composed of a plurality of thermochromic units 210, and the color-changing temperatures corresponding to each thermochromic unit 210 are different.

[0108] In a specific embodiment, different thermochromic units 210 display different colors when they sense that the aerosol supply system reaches their respective color-changing temperatures. With such a setting, the temperature can be indicated by different thermochromic units 210 displaying different colors.

[0109] In another specific embodiment, some of the thermochromic units 210 have the same color-changing temperature, and some of the thermochromic units 210 have different color-changing temperatures, but all the thermochromic units 210 display the same color when they sense that the aerosol supply system reaches their respective color-changing temperatures. With such a setting, different numbers of thermochromic units 210 can display the same color when the system reaches different color-changing temperatures, so that the thermochromic units 210 display different numbers of color blocks at different temperatures, thereby realizing the purpose of prompting the user of the temperature by the number of the displayed color blocks. Preferably, the mapping relationship between the number of the thermochromic units 210 with the same color-changing temperature and the specific temperature value can also be preset in advance, so that the temperature reached by the housing or the heating area of the current aerosol supply system can be inferred according to the mapping relationship and the number of the displayed color blocks.

[0110] In a specific embodiment, it can also be set that the color-changing temperatures corresponding to each thermochromic unit 210 are the same, but the distances of each thermochromic unit 210 from the heating area are different. Those skilled in the art know that the closer to the heating area, the higher the corresponding temperature, and vice versa, the farther from the heating area, the lower the corresponding temperature. Therefore, the thermochromic units 210 at different distances from the heating area will sense the aerosol supply system reaching the color-changing temperature at different times, so as to achieve the purpose of using the same thermochromic unit 210 to indicate that different positions of the aerosol supply system reach the color-changing temperature.

[0111] As a preferred embodiment, in the embodiments of the present application, a plurality of thermochromic units 210 are arranged on the housing 100 according to a preset arrangement manner. Thereby, the aesthetic appearance and the interestingness of the product can be improved.

[0112] In a specific embodiment, the temperature-sensitive color-changing unit 210 can be set in a strip shape, such as a rectangle. Further referring to Figure 2 As shown, a plurality of rectangular temperature-sensitive color-changing units 210 are sequentially attached to the surface of the housing 100 along the direction close to or away from the heating area of the aerosol system. Further, the initial colors of the temperature-sensitive color-changing materials of different temperature-sensitive color-changing units 210 are the same in the initial state, but their respective corresponding color-changing temperatures are different, and the colors displayed when reaching their respective color-changing temperatures are also different. Exemplarily, the temperature-sensitive color-changing unit 210 can be set to include four. The initial colors of the temperature-sensitive color-changing materials of the four temperature-sensitive color-changing units 210 can be the same as the color of the housing, such as black, and their respective corresponding color-changing temperatures are 45°C, 130°C, 260°C, and 350°C respectively. When reaching their respective color-changing temperatures, they can respectively display other colors that gradually deepen and are different from the initial color, such as gradually deepening red, etc.

[0113] In another specific embodiment, referring to FIG. 3, the temperature-sensitive color-changing unit 210 can be set in a fan shape, and a plurality of temperature-sensitive color-changing units 210 are spliced into at least a partial circle and attached to the surface of the housing 100. Taking the splicing into a circle as an example, the temperature-sensitive color-changing unit 210 can also be set to include four. The four temperature-sensitive color-changing units 210 are spliced into a circle and attached or embedded on the surface of the housing 100, or attached or embedded on the indicator light button provided on the housing. The initial colors of the temperature-sensitive color-changing materials of the four temperature-sensitive color-changing units 210 are the same in the initial state, but their respective corresponding color-changing temperatures are different, and the colors displayed when reaching their respective color-changing temperatures are also different. The specific setting method can be selected according to actual needs and will not be elaborated here.

[0114] As a preferred implementation manner, in the embodiment of the present application, a plurality of temperature-sensitive color-changing units 210 can also be set to be stacked along the direction towards or away from one side surface of the housing, that is, a plurality of temperature-sensitive color-changing units are stacked and then attached or embedded on the housing 100. In a specific embodiment, the initial colors of the temperature-sensitive color-changing materials of a plurality of temperature-sensitive color-changing units 210 are all transparent in the initial state, their respective corresponding color-changing temperatures are different, and the colors displayed when reaching their respective color-changing temperatures are also different. In another specific embodiment, the initial colors of the temperature-sensitive color-changing materials of a plurality of temperature-sensitive color-changing units 210 are different non-transparent colors (such as black, etc.) in the initial state, their respective corresponding color-changing temperatures are different, and they all become transparent when reaching their respective color-changing temperatures. Along the direction towards one side surface of the housing, the color-changing temperatures of the temperature-sensitive color-changing units 210 are getting higher and higher.

[0115] It can be understood that the costs of different thermochromic materials may vary. Using a variety of thermochromic materials to indicate the temperature may increase the production cost. Based on the design requirements of some products, it is necessary to make the temperatures sensed by the thermochromic units in different regions different. To solve the above problems, in the embodiments of the present application, a heat insulation member (not shown in the figure) can be selectively disposed between the thermochromic unit and the housing. Further, according to actual needs, the number of heat insulation members disposed between the thermochromic unit and the housing can be set to further make the temperatures sensed by different thermochromic units at the same moment different.

[0116] In a preferred embodiment, the heat insulation member in the embodiments of the present application can be made of ceramic fiber cotton or any one of aerogel heat insulation materials, and the present application does not make specific limitations in this regard.

[0117] When thermochromic materials of different temperatures are mixed together, they will display the mixed color, which follows the color matching principle of the three primary colors. For example: a thermochromic material that shows red at 10 degrees and a thermochromic material that shows yellow at 30 degrees are mixed together. In an environment below 10 degrees, it will show the effect of red + yellow = orange. When the temperature is higher than 10 degrees, the thermochromic material that shows red will be in a colorless state and has changed to a transparent color and does not show color, and the mixed material will show yellow. When the temperature is higher than 30 degrees, the thermochromic material that shows yellow at 30 degrees will also gradually change color. Eventually, the mixed powder will show transparent or white. Based on this, in a preferred embodiment, in the embodiments of the present application, the thermochromic materials included in the thermochromic module 200 can be made of a variety of mixtures, and the color-changing temperatures corresponding to different thermochromic materials are different. The colors shown by different thermochromic materials when the system reaches their respective corresponding color-changing temperatures are also different. When the thermochromic module senses that the aerosol supply system reaches different color-changing temperatures, the thermochromic material corresponding to the color-changing temperature shows the corresponding color to indicate the temperature level.

[0118] In a preferred embodiment, in the embodiments of the present application, the thermochromic material includes but is not limited to reversible thermosensitive ink. The reversible thermosensitive ink includes at least one of organic reversible thermosensitive ink and inorganic reversible thermosensitive ink.

[0119] Specifically, the organic reversible thermosensitive ink includes a color developer and a chromogenic agent. The chromogenic agent emits electrons to the color developer, thereby causing color development. Commonly used chromogenic agents include crystal violet lactone, malachite green lactone, methyl red, etc. Commonly used color developers include: phenolic hydroxyl compounds and their derivatives, such as bisphenol A, lauryl alcoholate, 8-hydroxyquinoline, benzyl p-hydroxybenzoate, 4-hydroxycoumarin, α-naphthol, β-naphthol, etc.; carboxyl compounds and their derivatives, etc.

[0120] Specifically, the inorganic reversible thermosensitive ink includes crystal transformation discoloration materials, materials that gain or lose crystal water and change color, or materials that change color due to changes in the geometric configuration of ligands. Among them, the crystal transformation discoloration materials include, but are not limited to, CuHgI4. When the temperature reaches 344K, the red tetragonal crystal system of CuHgI4 changes to the black cubic crystal system of Cu2HgI4, that is, the color changes due to the change in crystal form; the materials that gain or lose crystal water and change color include, but are not limited to, CoCl2·6H2O. When the temperature reaches 314K, the red CoCl2·6H2O loses water and becomes sky-blue CoCl2, that is, the color change is caused by the loss of water; the materials that change color due to changes in the geometric configuration of ligands include, but are not limited to, [(C2H5)2NH2]2CuCl4. When the temperature reaches 316K, the color of [(C2H5)2NH2]2CuCl4 reversibly changes between green and yellow, which is mainly caused by changes in structure or coordination number.

[0121] It can be understood that in the embodiments of the present application, a protection module is provided on the display surface of the temperature-sensitive color-changing module 100, which is mainly used to protect the temperature-sensitive color-changing module from being worn or contaminated and improve its service life.
