[0029] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0030] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0031] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0032] Heated non-combustible devices can heat an aerosol matrix to generate an aerosol. The aerosol matrix is ​​a solid structure containing only matrix components. When the heated non-combustible matrix is ​​heated, its volume shrinks. When the heated non-combustible matrix is ​​opened and the used one is taken out, it is easy to fall and cause burns to the user.

[0033] To address the aforementioned issues, this application provides a heat-not-burning device that senses temperature changes to alert the user to the current temperature, preventing the user from opening the device at high temperatures to remove the used heat-not-burning substrate and reducing the risk of burns.

[0034] See Figures 1-5 As shown, the heated non-combustible device provided in this application includes a main unit 10, a suction nozzle mechanism 20, and a reminder component 30.

[0035] The main unit 10 includes a housing 11 and a heating assembly 12, the heating assembly 12 being installed inside the housing 11, such as... Figures 3-5 As shown, the heating assembly 12 is provided with a heating chamber 121, which has an opening 122 facing the side of the housing 11. The heating chamber 121 is used to contain the heat-non-combustible matrix, and the heating assembly 12 is used to heat the heat-non-combustible matrix. The heat-non-combustible matrix can generate aerosol after being heated.

[0036] In use, the heat-not-burning substrate is placed in the heating chamber 121 through the opening 122, and the heating component 12 can heat the heat-not-burning substrate to generate an aerosol.

[0037] The suction mechanism 20 includes a cover 21 and a suction nozzle 22. The suction nozzle 22 is disposed on the cover 21. In a specific embodiment, the suction nozzle 22 passes through the cover 21 and defines an aerosol outflow channel 221. The cover 21 is movably connected to the housing 11 to open or close the opening 122 of the heating chamber 121. When the cover 21 closes the opening 122, the aerosol outflow channel 221 remains in communication with the heating chamber 121.

[0038] In this embodiment, the cover 21 and the shell 11 can be connected by sliding fit, hinge or other means, so that the opening 122 of the heating chamber 121 can be opened or closed. Only when the cover 21 closes the opening 122 can the aerosol outflow channel 221 and the heating chamber 121 be kept in communication.

[0039] When the aerosol outlet channel 221 is connected to the heating chamber 121, the aerosol generated by the heating component 12 heating the non-combustible matrix is ​​output through the aerosol outlet channel 221 for user use.

[0040] In this application, the cover 21 is hinged to the shell 11 so as to open or close the opening 122 of the heating chamber 121 by flipping the cover 21.

[0041] The reminder component 30 is disposed on the housing 11 and / or the cover 21, and the reminder component 30 is in thermal contact or electrically connected to the heating component 12. The reminder component 30 is used to issue a visual reminder signal when the temperature of the heating component 12 is higher than a preset threshold.

[0042] The visual reminder signal emitted by the reminder component 30 can be information such as light, color change, temperature value display, etc., and can be restored to the initial state when the temperature of the heating component 12 is lower than a preset threshold, thereby generating a reversible visual reminder signal.

[0043] The preset threshold temperature of the heating component 12 can burn the user. When the heating component 12 heats the heat-not-burning substrate in the heating chamber 121, it needs to generate a temperature that allows the heat-not-burning substrate to generate aerosol. This temperature is usually high and is the preset threshold. When it is necessary to replace the used heat-not-burning substrate, after opening the cover 21, the user needs to take the heated heat-not-burning substrate out of the heating chamber 121 through the opening 122. During this process, there is a risk of burning the user.

[0044] In this application, the high temperature generated by the heating component 12 during heating is conducted to the housing 11 and / or the cover 21. An alert component 30 is provided on the housing 11 and / or the cover 21. After the high temperature generated by the heating component 12 is conducted to the housing 11 and / or the cover 21, the alert component 30 can issue a visual alert signal when the temperature exceeds a preset threshold. This allows the user to observe the temperature of the heated non-combustible substrate that has been heated. Under the premise of the visual alert signal issued at the preset threshold, the user can choose not to touch the housing 11 and / or the cover 21, thereby reducing the risk of burns. When the temperature falls below the preset threshold, the alert component 30 can return to its initial state. At this temperature, the user will not be burned by the temperature below the preset threshold, and the user can open the cover 21 to remove the heated non-combustible substrate from the heating chamber 121 through the opening 122.

[0045] See Figure 4 As shown, the heating assembly 12 includes a heating element 13 and a heating cup 14. The heating element 13 is disposed inside the heating cup 14 and defines a heating chamber 121 above the heating element 13 with the inner cavity of the heating cup 14. The heating element 13 has multiple heat exchange air passages 131. The cup body of the heating cup 14 is provided with a first air passage 141, which is connected to the multiple heat exchange air passages 131. The suction nozzle 22 is provided with a second air passage 222 and an air inlet 223 connected to the second air passage 222. When the cover 21 is closed on the shell 11, the first air passage 141 and the second air passage 222 are connected. The user draws air through the suction nozzle 22, so that the outside air enters the first air passage 141 through the second air passage 222 via the air inlet 223, and then enters the heat exchange air passage 131 through the first air passage 141. The heating element 13 heats the airflow flowing through the heat exchange air passage 131, so that the airflow heats up rapidly to heat the heat-non-combustible matrix in the heating chamber 121 to generate an aerosol.

[0046] See also Figure 4 As shown, a one-way valve 23 is also provided between the shell 11 and the cover 21. One end of the one-way valve 23 is connected to the first air passage 141 and / or the second air passage 222, and the other end is connected to the heating chamber 121. The one-way valve 23 can guide part of the airflow flowing through the first air passage 141 and the second air passage 22 to the heating chamber 121 in one direction, so as to achieve the purpose of mixing and cooling with the generated aerosol.

[0047] In this embodiment, the nozzle 22 is provided with a collection chamber 2211, an acceleration air passage 2212, and a buffer chamber 2213 connected in sequence inside. The collection chamber 2211, the acceleration air passage 2212, and the buffer chamber 2213 connected in sequence constitute an aerosol outflow channel 221. The collection chamber 2211 and the heating chamber 121 are interconnected after the cover 11 is connected to the shell 21. The generated aerosol first enters the collection chamber 2211 and mixes fully with the outside gas. The acceleration air passage 2212 can accelerate the flow of the aerosol after it is fully mixed with the outside gas to the buffer chamber 2213 to reduce suction resistance and improve user experience. The aerosol in the buffer chamber 2213 is output through the aerosol outflow channel 221 and used by the user.

[0048] See Figure 1 as well as Figure 5 As shown, in one embodiment of this application, the reminder component 30 includes a temperature sensing element 31 and an electroluminescent indicator unit 32. The temperature sensing element 31 is in thermal contact with the heating component 12 and can sense the temperature of the heating component 12 in real time. The electroluminescent indicator unit 32 is disposed on the housing 11 and / or the cover 21, and is electrically connected to the temperature sensing element 31. The electroluminescent indicator unit 32 is used to issue a visual reminder signal when the temperature of the heating component 12 sensed by the temperature sensing element 31 is higher than a preset threshold.

[0049] In this embodiment, the heating component 12 is disposed inside the housing 11. In order to enable the temperature sensing element 31 to accurately sense the temperature value of the heating component 12, the temperature sensing element 31 can be disposed inside the housing 11 to achieve a thermal contact connection between the temperature sensing element 31 and the heating component 12. This can avoid heat loss caused by heat conduction through the housing 11, thereby improving the accuracy of temperature sensing.

[0050] See Figure 6 As shown, the electroluminescent indicator unit 32 includes a light source 321, which is electrically connected to the temperature sensing element 31. The light source 321 can emit light signals, such as red light, blue light, yellow light, etc. The visual reminder signal is the light signal emitted by the light source 321 when the temperature of the heating component 12 sensed by the temperature sensing element 31 is higher than a preset threshold.

[0051] To further ensure that users can accurately distinguish the light signal emitted by the light source 321 from the outer surface of the housing 11 and / or the outer surface of the cover 21, the color of the light signal emitted by the light source 321 is set to be a different color from the color of the outer surface of the housing 11 and / or the outer surface of the cover 21. For example, the color of the light signal emitted by the light source 321 is red, while the outer surface of the housing 11 and the outer surface of the cover 21 can both be white to distinguish them.

[0052] See also Figure 6As shown, the electroluminescent indicator unit 32 includes a display module 322, which is disposed on the outer surface of the housing 11 or the cover 21. The display module 322 is electrically connected to the temperature sensing element 31. The display module 322 can display the current temperature value of the heating component 12 sensed by the temperature sensing element 31, or it can display a light signal when the temperature sensing element 31 senses that the current temperature of the heating component 12 is higher than a preset threshold. The display module 322 is a display screen. By comparing the current temperature value of the heating component 12 sensed by the temperature sensing element 31 with the preset threshold, the difference between the current temperature and the preset threshold can be determined. When the current temperature is greater than the preset threshold, the display module 322 displays a light signal of the same color in full screen to warn the user. When the current temperature is less than the preset threshold, the display module 322 is in a non-working state, that is, there is no display information. Alternatively, by processing the current temperature value of the heating component 12 sensed by the temperature sensing element 31, the display module 322 can display the current temperature value.

[0053] Therefore, the visual alert signal is a light signal and / or text information of the temperature value displayed by the display module 322 when the temperature of the heating component 12 sensed by the temperature sensing element 31 is higher than a preset threshold. In other words, the display module 322 can display the temperature value and the light signal at the same time. For example, the display module 322 can display the temperature value and the light signal at intervals. Alternatively, in the same display interface, the display module 322 can display the temperature value in the middle and the light signal around the middle to achieve the function of dual warning.

[0054] In this application, the electroluminescent indicator unit 32 may employ both a light source 321 and a display module 322, or it may employ only a light source 321 or a display module 322, depending on actual needs.

[0055] See Figure 7 As shown, the reminder component 30 includes a thermochromic unit 33, which is disposed on the housing 11 and / or the cover 21. The thermochromic unit 33 can change color when the temperature of the heating component 12 is higher than a preset threshold, and revert to its initial color when the temperature of the heating component 12 is lower than the preset threshold. Furthermore, to facilitate differentiation between the thermochromic unit 33 and the outer surface color of the housing 11 and / or the cover 21 after the color change, the color of the thermochromic unit 33 when the temperature of the heating component 12 is higher than the preset threshold should be different from the outer surface color of the housing 11 and / or the cover 21.

[0056] Therefore, the visual alert signal is the first color generated by the thermochromic unit 33 when the temperature of the heating component 12 is higher than a preset threshold. This first color is different from the outer surface color of the housing 11 and / or the cover 21. For example, the first color generated by the thermochromic unit 33 when the temperature of the heating component 12 is higher than the preset threshold is red, while the outer surface color of the housing 11 and the cover 21 is white.

[0057] In this embodiment, the color of the thermochromic unit 33 when it is not thermochromic or when the temperature of the heating component 12 is below a preset threshold is a second color. This second color is the initial color restored by the thermochromic unit 33 when it is not thermochromic or when the temperature of the heating component 12 is below the preset threshold. Since the second color is different from the first color, it helps the user determine whether the temperature of the heating component 12 has decreased below the preset threshold. For example, the first color is red, and the second color is yellow.

[0058] In some embodiments of this application, the second color may be the same as or different from the color of the outer surface of the housing 11 and / or the cover 21. Under the same conditions, the second color is either white or yellow, which ensures color consistency of the housing 11 and the cover 21 when the thermochromic unit 33 does not change color or the temperature of the heating component 12 is below a preset threshold. However, in different cases, the second color may be yellow, while the outer surface color of the housing 11 and the cover 21 may be white.

[0059] In this application, the outer surface color of the housing 11 may be the same as or different from the outer surface color of the cover 21. For example, under the same circumstances, the first color is red, and the second color may be white or yellow, which are the same as the outer surface color of the housing 11 and the outer surface color of the cover 21. Alternatively, the second color may be green, and the outer surface color of the housing 11 and the outer surface color of the cover 21 may be white or yellow. Under different circumstances, the first color is red, the second color is green, the outer surface color of the housing 11 is white, and the outer surface color of the cover 21 is yellow.

[0060] To enable the thermochromic unit 33 to quickly and accurately produce different color changes according to the temperature changes of the heating component 12, the thermochromic unit 33 is disposed on the outer surface of the housing 11 and / or the cover 21 and is in thermal contact with the heating component 12. For example, the thermochromic unit 33 is in direct contact with the heating component 12, or the thermochromic unit 33 is in indirect contact with the heating component 12 through a heat-conducting element, thereby smoothly transferring the temperature of the heating component 12 to the thermochromic unit 33.

[0061] In this embodiment, the thermochromic unit 33 can be a thermochromic coating applied to the outer surface of the housing 11 and / or the cover 21. The thermochromic coating can produce different color changes when the ambient temperature changes, and the color change is reversible. In this application, when the ambient temperature changes (the temperature of the heating component 12 is greater than a preset threshold), the color change of the thermochromic unit 33 is the first color, and when the ambient temperature returns to the initial temperature (the temperature of the heating component 12 is less than the preset threshold), the reversible color of the thermochromic unit 33 is the second color.

[0062] In summary, in the heat-not-burning device provided by this utility model, the high temperature generated by the heating component during heating is conducted to the shell or cover. An alerting component is provided on the shell and / or cover. The alerting component can issue a visual alert signal when the temperature of the heating component is higher than a preset threshold, so that the user can observe the temperature of the heat-not-burning substrate that has been heated. Under the premise of the visual alert signal issued at the preset threshold, the user can choose not to touch the shell and cover, thereby reducing the risk of burns.

[0063] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
