[0025] This application provides an aerosol generating device that uses color display to allow users to obtain temperature information of the aerosol generating device, so as to avoid the aerosol generating device from burning their hands or the generated aerosol from burning their mouths.
[0026] Please refer to the aerosol generating apparatus of this application embodiment. Figures 1 to 3 The device includes a main body 1 and a temperature display 2. The main body 1 includes a housing 11, a battery cell 12, an aerosol generating component 13, and a support assembly 14. The battery cell 12, the aerosol generating component 13, and the support assembly 14 are all located inside the housing 11. The support assembly 14 is fixedly connected to the housing 11, and the battery cell 12 and the aerosol generating component 13 are both mounted on the support assembly 14. The aerosol generating component 13 has a receiving cavity (not shown in the figure) and a heating element (not shown in the figure). The housing 11 has an aerosol outlet 112 communicating with the receiving cavity. The aerosol product 3 can be inserted into the receiving cavity from the aerosol outlet 112. The heating element can heat the aerosol product 3 in the receiving cavity to generate aerosol.
[0027] The housing 11 has a light-transmitting portion 114, and the support assembly 14 has a mounting position 147 facing the light-transmitting portion 114 in a first direction. In some embodiments, the first direction may be aligned with the aerosol outlet 112, or, for ease of assembly of the housing 11, in some embodiments, the first direction may also be perpendicular to the aerosol outlet 112. A temperature display 2 is located inside the housing 11 and is fixed to the mounting position 147. At least a portion of the temperature display 2 is made of a thermochromic material. In one embodiment, the temperature display 2 is entirely made of a thermochromic material, or in another embodiment, the temperature display 2 includes a main body and a temperature display layer coated or adhered to the outer surface of the main body. This temperature display layer may be made of a thermochromic material. The thermochromic material allows the temperature display 2 to be configured to display different colors according to its temperature changes. The color information displayed by the temperature display 2 is obtained by the user through the light-transmitting portion 114 on the housing 11, facilitating the user to obtain the current operating temperature of the aerosol generating device.
[0028] The special compounds in thermochromic materials change color when heated. Thermochromic materials can be inorganic, liquid crystal, or organic. By changing the ratio of the mixture in the thermochromic material, the thermochromic material can display different colors in different temperature ranges.
[0029] In some embodiments, the thermochromic material can be set to display blue (i.e., the temperature display 2 is blue) when the temperature is between -20°C and 10°C, indicating that the temperature of the aerosol generating device is too low and continued operation of the aerosol generating device will damage the battery cell 12; when the temperature is between 10°C and 37°C, the thermochromic material displays green (i.e., the temperature display 2 is green), indicating that the current temperature is most suitable for the aerosol generating device; when the temperature is between 37°C and 55°C, the thermochromic material displays yellow (i.e., the temperature display 2 is yellow), indicating that the aerosol generating device can be used at the current temperature; when the temperature is between 55°C and 70°C, the thermochromic material displays red, indicating that the current temperature is too high and continued operation of the aerosol generating device may cause burns to the hands or the generated aerosols may burn the mouth. The temperature display 2 in the aerosol generating device can serve as a reminder to the user. By observing the color of the temperature display 2, the user can determine whether the aerosol generating device is suitable for continued use under the current temperature conditions. The display can also remind the user when the temperature of the aerosol generating device is too high, so as to avoid the aerosol generating device burning the user's hands or the aerosol burning the user's mouth.
[0030] In some embodiments, please refer to Figure 2 and Figure 3 The mounting position 147 on the bracket assembly 14 has a mounting groove 148. The opening of the mounting groove 148 faces the light-transmitting part 114 in the first direction. The temperature display 2 can be a cuboid block structure. The outer contour shape of the mounting groove 148 matches the outer contour shape of the temperature display 2. The temperature display 2 can be located in the mounting groove 148. The temperature display 2 can be fixed in the mounting groove 148 by adhesive, or the temperature display 2 can also be installed in the mounting groove 148 by interference fit to determine the specific position of the temperature display 2 in the housing 11 and prevent the temperature display 2 from falling out of the mounting groove 148.
[0031] In some embodiments, please continue to refer to Figure 2 and Figure 3 The main body 1 of the device includes a fixing member 15 located within the outer casing 11. The fixing member 15 is located on the side of the bracket assembly 14 facing the light-transmitting portion 114 in a first direction. The fixing member 15 is mounted on the bracket assembly 14, and the temperature display 2 can be clamped and fixed in the mounting groove 148 by the relative fixation between the fixing member 15 and the bracket assembly 14, so as to prevent the temperature display 2 from falling out of the mounting groove 148. In other embodiments, the fixing member 15 may not be provided in the main body 1 of the device, and the temperature display 2 may be fixed in the mounting groove 148 or mounting position 147 of the bracket assembly 14 by means of snap-fit connection or adhesive.
[0032] In an embodiment where the main body 1 of the device includes a fastener 15, the fastener 15 has a light-transmitting area located between the temperature display 2 and the light-transmitting part 114 in a first direction. The light-transmitting area can be formed by a hollow structure, or the fastener 15 in the light-transmitting area can be made of a light-transmitting material. In this way, the color information displayed by the temperature display 2 can be obtained by the user through the light-transmitting area and the light-transmitting part 114 in sequence.
[0033] In some embodiments, the depth of the mounting groove 148 is greater than or equal to the dimension of the temperature display 2 in the first direction. The fixing member 15 is a light-transmitting plate structure. The fixing member 15 may be made of glass or light-transmitting plastic. The mounting position 147 on the bracket assembly 14 has a mounting plane facing the first direction. The fixing member 15 can be fixed to the mounting plane by adhesive or snap-fit connection to encapsulate and fix the temperature display 2 in the mounting groove 148.
[0034] In some embodiments, the bracket assembly 14 has a positioning groove 149, the opening of the positioning groove 149 facing the light-transmitting portion 114 in a first direction, the mounting position 147 and the mounting plane are both located on the bottom wall of the positioning groove 149, the outer contour shape of the fixing member 15 matches the outer contour shape of the positioning groove 149, the fixing member 15 is located in the positioning groove 149 to achieve the pre-positioning of the fixing member 15, which facilitates the fixed connection between the fixing member 15 and the bracket assembly 14, and helps to achieve the consistency of the internal structure of the device body 1.
[0035] In other embodiments, the bracket assembly 14 does not have a mounting groove 148 and / or a positioning groove 149. The bracket assembly 14 has a plane facing the light-transmitting portion 114 in a first direction. The temperature display 2 and the fixing member 15 are both fixedly mounted on the plane of the bracket assembly 14, as long as the temperature display 2 is relatively fixed to the bracket assembly 14 and the color information of the temperature display 2 can be seen by the user through the light-transmitting portion 114.
[0036] In some embodiments, please continue to refer to Figure 2 and Figure 3The aerosol generating device also includes a display screen assembly 16, which is located inside the housing 11.

The temperature display 2 is arranged close to the display screen 161. In the plane perpendicular to the first direction, the orthographic projections of the temperature display 2 and the display screen 161 are located within the orthographic projection coverage of the light-transmitting part 114, so that the user can obtain the color information displayed by the temperature display 2 and the working parameter information displayed on the display screen 161 in the aerosol generating device through the light-transmitting part 114. This eliminates the need to set up a separate light-transmitting area on the housing 11 specifically for obtaining the color information on the temperature display 2 or the working parameter information on the display screen 161, which helps to simplify the structure of the entire aerosol generating device.
[0037] In some embodiments, the display assembly 16 further includes a circuit board 162, on which the display screen 161 is fixedly mounted and electrically connected. The display screen 161 can be mounted and fixed on the bracket assembly 14 via the circuit board 162. The bracket assembly 14 may be made of metal or plastic material and includes a first bracket 141 and a second bracket 142 arranged in a first direction. The first bracket 141 is fixed relative to the housing 11, and the second bracket 142 is fixedly connected to the first bracket 141. The circuit board 162 is clamped and fixed between the first bracket 141 and the second bracket 142 in the first direction to realize the mounting and fixing of the display assembly 16 on the bracket assembly 14. The second bracket 142 is located between the first bracket 141 and the light-transmitting part 114 in the first direction. The second bracket 142 is a frame structure and surrounds the display area of the display screen 161 in a plane perpendicular to the first direction. The mounting position 147 for mounting and fixing the temperature display 2 is located on the second bracket 142. In this way, the temperature display 2 is close to the display assembly 16. The temperature display 2 can detect the temperature at the location of the display assembly 16, which helps to prevent the display assembly 16 from being damaged due to overheating and can ensure the normal operation of the display assembly 16.
[0038] In other embodiments, the second bracket 142 may not be provided in the bracket assembly 14. The circuit board 162 is mounted on the first bracket 141 by screws. The mounting position 147 for mounting and fixing the temperature display 2 is located on the first bracket 141, and the temperature display 2 is set close to the display screen 161.
[0039] In other embodiments, the aerosol generating device may not include a display screen assembly 16, and the temperature of the device body 1 may be detected only by a temperature display 2.
[0040] In some embodiments, the second support 142 includes a first pressing part 143 and a second pressing part 145 arranged in a first direction. The second pressing part 145 is located on the side of the first pressing part 143 facing away from the first support 141 in the first direction. The first pressing part 143 has a first hook 144, which can be connected to the first support 141. The second pressing part 145 has a second hook 146, which can be connected to the first pressing part 143. In the circumferential direction perpendicular to the first direction and surrounding the display screen 161, the first hook 144 and the second hook 146 are staggered, and the second hook 146 is located between two adjacent first hooks 144. Of course, in other embodiments, the second support 142 can also be an integral structure, that is, the first pressing part 143 and the second pressing part 145 are integrally formed, which helps to simplify the structure of the support assembly 14 and facilitates the assembly of the aerosol generating device.
[0041] In some embodiments, please refer to Figure 3 For the outer shell 11, the outer shell 11 includes a first shell 111 and a second shell 113 arranged in a first direction. The first shell 111 and the second shell 113 can be connected by hooks or by interference fit. The light-transmitting part 114 is located on the second shell 113. The first shell 111 is integrally made of opaque material. In one embodiment, the second shell 113 can be made of light-transmitting glass or transparent plastic material. The second shell 113 as a whole can form the light-transmitting part 114.
[0042] In one embodiment, the second housing 113 is provided separately. The second housing 113 includes a housing body and a light-transmitting window. The housing body can be made of opaque material and has perforations. A light-transmitting plate can be installed and fixed in the perforations by hooks. The light-transmitting plate can be made of light-transmitting plastic or glass. The light-transmitting plate forms the light-transmitting part 114 on the second housing 113. The user can obtain the color information of the temperature display 2 and the working parameters of the aerosol generating device in the display screen 161 through the light-transmitting plate at the light-transmitting window.
