[0039] The present application discloses a low-temperature resistant power supply component, a low-temperature resistant power supply device, and a low-temperature resistant aerosol generating device, which include some or all of the technical features of the following embodiments; that is, the low-temperature resistant power supply component, the low-temperature resistant power supply device, and the low-temperature resistant aerosol generating device include some or all of the following structures. In one embodiment of the present application, a low-temperature resistant power supply component includes a housing, a heating element, and a switch assembly; the housing is provided with a battery cavity for accommodating a battery, the heating element is arranged in the battery cavity, and the heating element is used to be thermally conductively arranged with the battery; the switch assembly is arranged on the housing, and the heating element is also used to conductively connect the battery through the switch assembly, so that when the switch assembly is in the on state, the heating element is conductively connected to the battery, and when the switch assembly is in the off state, the heating element is disconnected from the battery. The above-mentioned low-temperature resistant power supply assembly, by setting a heating element in the battery cavity, uses the battery's own energy to provide a suitable warm environment for the battery when the ambient temperature is too low, so that the battery working environment is within the normal temperature range. Since it stimulates the battery's own energy, it does not violate the principle of energy conservation, but effectively stimulates the battery's own energy that cannot be used in a low-temperature environment, avoiding the performance degradation and discharge capacity reduction of the battery caused by low temperature, and ensuring the normal use time of products using the battery, such as an aerosol generating device, in a low-temperature environment. The low-temperature resistant power supply assembly, the low-temperature resistant power supply device, and the low-temperature resistant aerosol generating device are described in detail below in conjunction with Figures 1 to 17.

[0040] In one embodiment, a low temperature resistant power supply assembly 100 is shown in FIG1, which includes a housing 110, a heating element 120 and a switch assembly 150; in conjunction with FIG2, the housing 110 is provided with a battery cavity 111 for accommodating a battery 200, the heating element 120 is arranged in the battery cavity 111, and the heating element 120 is used for heat conduction with the battery 200, that is, the heating element 120 is used for generating heat and transferring heat energy to the battery 200; exemplarily, the heat conduction arrangement includes conduction and convection of heat energy, the conduction of heat energy includes transferring heat energy to the battery 200 in a direct or indirect contact manner, and the convection of heat energy includes transferring heat energy to the battery 200 through air. Exemplarily, the housing 110 is also provided with other chambers such as a liquid storage chamber 112 for storing liquid. It can be understood that when the liquid storage chamber 112 is used for storing objects, it can be called a storage chamber, and the embodiments of the present application do not impose special restrictions on this. For products applied to the aerosol generating assembly 800, the low temperature resistant power supply assembly 100 may also be referred to as the low temperature resistant power supply assembly 100 for aerosol generation.

[0041] Illustratively, in one embodiment, a low-temperature-resistant power supply device 700 is shown in FIG. 2, which includes a battery 200 and the low-temperature-resistant power supply component 100 described in any embodiment, wherein the battery 200 is disposed in the battery cavity 111 of the low-temperature-resistant power supply component 100, and is conductively connected to the heating element 120 of the low-temperature-resistant power supply component 100 through the switch component 150 of the low-temperature-resistant power supply component 100. The low-temperature-resistant power supply device 700 also has the advantages of the low-temperature-resistant power supply component 100, which will not be elaborated here. Similarly, for products used in an aerosol generating component 800, the low-temperature-resistant power supply device 700 can also be referred to as a low-temperature-resistant power supply device 700 for aerosol generation.

[0042] In order to facilitate the transfer of heat energy to the battery 200, in one embodiment, the heating element 120 is used to be close to the battery 200 to heat the battery 200 by conduction; such a structural design is conducive to quickly transferring heat energy to the battery 200, quickly increasing the ambient temperature inside the battery cavity 111, so that the working environment of the battery 200 is within a normal temperature range.

[0043] Considering the safety issue, in one embodiment, as shown in FIG. 2 or FIG. 3, the heating element 120 is used to be arranged around the battery 200, and a spacer 116 is left between the heating element 120 and the battery 200 to heat the battery 200 by air convection. Such a structural design, on the one hand, is conducive to quickly raising the ambient temperature inside the battery cavity 111, transferring heat energy to the battery 200, so that the working environment of the battery 200 is within the normal temperature range; on the other hand, it avoids the battery 200 from being damaged in case of leakage of the heating element 120.

[0044] In order to prevent a large amount of heat energy from being lost to the outside of the shell 110, in one embodiment, the battery cavity 111 is sealed. In one embodiment, the shell 110 is provided with a heat preservation layer on the wall of the battery cavity 111, that is, the inner wall of the shell 110 is provided with a heat preservation layer or a heat insulating layer for heat preservation. This is because the shell 110 is usually made of metal parts, and the heat preservation layer can be made of rubber parts or adhesive layers or coatings, etc., and the battery cavity 111 with a sealed setting has a better heat preservation effect, which prevents the heat energy inside the battery cavity 111 from being lost to the outside of the shell 110 in an extremely cold environment.

[0045] In each embodiment, the switch assembly 150 is disposed on the housing 110, and the heating element 120 is also used to be conductively connected to the battery 200 through the switch assembly 150, so that when the switch assembly 150 is in the on state, the heating element 120 is conductively connected to the battery 200, and when the switch assembly 150 is in the off state, the heating element 120 is conductively disconnected from the battery 200. That is, the switch assembly 150 controls the on and off of the heating element 120 and the battery 200, thereby controlling whether the heating element 120 can work. When the ambient temperature is too low, the battery 200 itself has energy but cannot release it, and can only release a part of it. The present application transfers part of the energy of the battery 200 to the heating element 120 to increase the temperature in the battery cavity 111, thereby stimulating the energy of the battery 200 itself. It can also be understood as increasing the ambient temperature in the battery cavity 111 under the external low temperature environment, thereby increasing the releasable energy of the battery 200 itself. Since the energy of the battery 200 itself is stimulated, it does not violate the principle of conservation of energy, but effectively stimulates the energy of the battery 200 itself that cannot be used in the low temperature environment, thereby avoiding the performance degradation and discharge capacity reduction of the battery 200 caused by low temperature, and ensuring the normal use time of products that use the battery 200 and are affected by low temperature, such as vehicles, ships, aircraft or aerosol generating devices, in a low temperature environment.

[0046] In order to facilitate the setting and connection of components, further, in one embodiment, as shown in Figure 3, the low-temperature resistant power supply component 100 also includes a control circuit board 140, and the switch component 150 is conductively connected to the heating element 120 through the control circuit board 140, and the control circuit board 140 is used to drive the heating element 120 to work; such a structural design is conducive to the setting and connection of components, and is convenient for modular production and assembly.

[0047] In order to facilitate rapid heating, in one embodiment, the low temperature resistant power supply component 100 is shown in FIG4. Different from the embodiment shown in FIG3, the heating element 120 has a larger heating area to achieve rapid heating of the battery cavity 111, thereby quickly stimulating the energy of the battery 200 itself that cannot be used in a low temperature environment. In this embodiment, the low temperature resistant power supply component 100 also includes a power adjustment module 190 arranged in the battery cavity 111 or on the housing 110, and the power adjustment module 190 is connected to the heating element 120, and is used to make the heating element 120 in a first output power state in the initial state, and adjust the heating element 120 in the adjustment state so that the heating element 120 is in a second output power state. Further, in one embodiment, the power adjustment module 190 is integrated with the switch component 150. Further, in one embodiment, the switch component 150 is connected to the heating element 120 through the power adjustment module 190. For the embodiment with the control circuit board 140, in one embodiment, the power regulating module 190 is disposed on the control circuit board 140. With such a structural design, when the external environment is very cold and affects the performance of the battery 200, the heating element 120 is first in the first output power state, so that the battery cavity 111 is heated up quickly; when the temperature of the battery cavity 111 rises to a certain level and the performance of the battery 200 is restored, the heating element 120 is in the second output power state, so that the battery cavity 111 is in a heat preservation or constant temperature state, avoiding wasting the energy of the battery 200, thereby achieving a balance between energy saving and stimulating the battery 200.

[0048] In order to facilitate the rapid transfer of heat energy to the battery 200, in one embodiment, as shown in FIG5 , the low temperature resistant power supply assembly 100 further includes a heat conductor 130, and the heating element 120 is used to abut the battery 200 through the heat conductor 130 to heat the battery 200 by conduction. In this embodiment, the low temperature resistant power supply assembly 100 further includes a control circuit board 140 and a temperature measuring assembly 160, and the temperature measuring assembly 160 can also be called a temperature sensing assembly. The switch assembly 150 is conductively connected to the heating element 120 through the control circuit board 140, and the control circuit board 140 is used to drive the heating element 120 to work; the temperature measuring assembly 160 is conductively connected to the control circuit board 140, and the temperature measuring assembly 160 is arranged in the battery cavity 111, and is used to detect the current temperature in the battery cavity 111 or on the surface of the battery 200 when the switch assembly 150 is in the on state, and when the current temperature is not higher than the first preset value, the heating element 120 is conductively connected to the battery 200, and the power regulating module 190 is in the initial state; when the current temperature is not lower than the second preset value, the power regulating module 190 is in the regulating state, or the switch assembly 150 is in the cut-off state. Further, in one embodiment, the temperature measuring assembly 160 is integrated with the power regulating module 190, or the temperature measuring assembly 160 is a temperature sensor or the temperature measuring assembly 160 includes a temperature sensor. Such a structural design is conducive to temperature control according to the temperature condition of the battery cavity 111 , thereby further achieving a balance between energy saving and stimulating the battery 200 .

[0049] The heating element 120 and the heat-conducting member 130 may have various connection relationships and positional relationships. Furthermore, in one embodiment, the heating element 120 is partially covered outside the heat-conducting member 130 as shown in FIG6. In this embodiment, the heating element 120 is a heating sheet. Alternatively, in one embodiment, as shown in FIG7, a groove is provided on the outer surface of the heat-conducting member 130 away from the battery 200, and the heating element 120 is embedded in the groove; or, the heating element 120 is a heating circuit, which is arranged on the outer surface 122 of the heat-conducting member 130 by thick film printing, etching, and resistance heating sheet embedding. Alternatively, in one embodiment, as shown in FIG8, the heating element 120 is wound around the outside of the heat-conducting member 130. In this embodiment, the heating element 120 is a mesh, such as a metal heating mesh. Such a structural design is conducive to the effective conduction of heat from the heating element 120 to different areas of the heat conductor 130 after it is working, thereby quickly heating up the battery cavity 111, thereby utilizing the energy of the battery 200 itself to provide a suitable warm environment for the battery 200, so that the working environment of the battery 200 is within a normal temperature range. Since the energy of the battery 200 itself is stimulated, it does not violate the principle of conservation of energy, but effectively stimulates the energy of the battery 200 itself that cannot be used in a low temperature environment, thereby avoiding the performance degradation and discharge capacity reduction of the battery 200 due to low temperature, and ensuring the normal use time of products using the battery 200, such as an aerosol generating device, in a low temperature environment.

[0050] The following is an example of the positional relationship between the heating element 120 and the battery 200 from another perspective. Further, in one embodiment, the heating element 120 is located on one side of the battery 200 as shown in FIG9. In this embodiment, a spacer 116 is left between the heating element 120 and the battery 200 to heat the battery 200 by air convection. Alternatively, in one embodiment, as shown in FIG10 or FIG12, the heating element 120 is arranged around the battery 200 in a semi-enclosed structure; in this embodiment, the heating element 120 is an incomplete rectangle with an opening 123; in other embodiments, the heating element 120 may also be an incomplete circle with an opening 123 or an incomplete ellipse with an opening 123. In the embodiment shown in FIG9 or FIG10, the heating element 120 is in a sheet shape; in other embodiments, the heating element 120 may also be in a wire shape, a mesh shape or other shapes, as long as it can use the energy of the battery 200 itself to generate heat to increase the temperature inside the battery cavity 111.

[0051] In the embodiment shown in FIG. 9 or FIG. 10, the outer shell 110 has a rectangular cross-section. In other embodiments, the outer shell 110 may also be in other shapes. In one embodiment, as shown in FIG. 11, the outer shell 110 has a circular cross-section. In this embodiment, the heating element 120 is located on one side of the battery 200, and there is a gap between the inner surface 121 of the heating element 120 and the battery 200, and there is also a gap between the outer surface 122 of the heating element 120 and the outer shell 110. Such a structural design is conducive to ensuring the safe use of the low-temperature resistant power supply component 100, avoiding the possibility of leakage that affects the safety of use, and also avoiding the loss of heat energy to the external environment due to the heating element 120 contacting the outer shell 110.

[0052] In one embodiment, the low temperature resistant power supply assembly 100 is shown in FIG. 12 . Different from the embodiment shown in FIG. 11 , the heating element 120 has a larger heating area. In this embodiment, the heating element 120 is in a non-complete circle with an opening 123 .

[0053] In one embodiment, the low temperature resistant power supply component 100 is shown in FIG. 13 . Different from the embodiment shown in FIG. 12 , the low temperature resistant power supply component 100 further includes a heat conductor 130 , and the heating element 120 is used to abut the battery 200 through the heat conductor 130 to heat the battery 200 by conduction.

[0054] In one embodiment, the low temperature resistant power supply assembly 100 further includes a heat conductor 130, the heat conductor 130 abuts against the heating element 120, and the heat conductor 130 is disposed between the heating element 120 and the battery 200. In this embodiment, the low temperature resistant power supply assembly 100 is shown in FIG14. Different from the embodiment shown in FIG13, a spacer 116 is left between the heat conductor 130 and the battery 200 to heat the battery 200 by air convection. Alternatively, in other embodiments, the spacer 116 may also be replaced by an insulating layer.

[0055] In one embodiment, as shown in FIG. 15 , the low temperature resistant power supply assembly 100 further includes an insulating layer 170 or the heat conductive member 130 has an insulating layer 170. In this embodiment, the heating element 120 abuts against the heat conductive member 130 through the insulating layer 170; in other embodiments, the heat conductive member 130 may abut against the battery 200 through the insulating layer 170. In this state, the heating element 120 abuts against the heat conductive member 130 or a spacer 116 is left between the heating element 120 and the heat conductive member 130. Such a structural design is conducive to improving the safety of the low temperature resistant power supply assembly 100 and preventing the heating element 120 from leaking electricity and affecting the safety of use.

[0056] In one embodiment, the low temperature resistant power supply assembly 100 is shown in FIG16 , and the heat conductive member 130 surrounds the heating element 120; in other embodiments, the heat conductive member 130 may also be located on both sides of the heating element 120. Such a structural design is conducive to improving the uniform heating effect of the heating element 120 on the battery cavity 111.

[0057] In one embodiment, a low-temperature-resistant aerosol generating device 900 is shown in FIG. 17 , which includes an aerosol generating component 800 and a low-temperature-resistant power supply device 700 described in any embodiment, and the low-temperature-resistant power supply device 700 is conductively connected to the aerosol generating component 800 for power supply. Such a structural design, by setting a heating element 120 in the battery cavity 111, uses the energy of the battery 200 itself to provide a suitable warm environment for the battery 200 when the ambient temperature is too low, so that the working environment of the battery 200 is within the normal temperature range. Since the energy of the battery 200 itself is stimulated, it does not violate the principle of energy conservation, but effectively stimulates the energy of the battery 200 itself that cannot be used in a low-temperature environment, avoids the performance reduction and discharge capacity reduction of the battery 200 caused by low temperature, and ensures the normal use time of products using the battery 200, such as aerosol generating devices, in a low-temperature environment.

[0058] Illustratively, in one of the embodiments, the low-temperature-resistant power supply component 100 of the low-temperature-resistant power supply device 700 is provided with a liquid storage chamber 112 and an air outlet channel 114 in its outer shell 110, and an air inlet 113 and an air outlet 115 connected to the air outlet channel 114 are also provided in the outer shell 110; the aerosol generating component 800 is in contact with the liquid storage chamber 112 to obtain the aerosol generating medium in the liquid storage chamber 112, and the aerosol generating medium is usually in liquid state and is used to form an aerosol when heated. The aerosol generating component 800 is conductively connected to the battery 200 of the low-temperature-resistant power supply device 700, and is used to generate aerosol, which is output to the air outlet 115 through the air outlet channel 114. With such a structural design, the outer shell 110 is an integral shell, and the aerosol generating component 800 is an integral component thereof.

[0059] Alternatively, in one embodiment, the aerosol generating assembly 800 is provided with an atomizing element, a liquid storage chamber 112, an air inlet 113, an air outlet channel 114 and an air outlet 115; the air inlet 113, the air outlet channel 114 and the air outlet 115 are sequentially connected, and the air inlet 113 and the air outlet 115 are connected to the external environment respectively; the atomizing element is in contact with the liquid storage chamber 112 or is arranged in the liquid storage chamber 112 to obtain the aerosol generating medium in the liquid storage chamber 112, and the atomizing element is conductively connected to the battery 200 of the low temperature resistant power supply device 700 to generate aerosol, which is output to the air outlet 115 through the air outlet channel 114. With such a structural design, the aerosol generating assembly 800 and the low temperature resistant power supply device 700 are respectively used as two independent components, which only need to be simply assembled, such as plug-in or screw-connected, when in use, and are easy to replace and use separately.

[0060] In one embodiment, the aerosol generating assembly 800 or its atomizing element includes a heating element 810 and a conductor 820, wherein the conductor 820 contacts the liquid storage chamber 112 to obtain the aerosol generating medium in the liquid storage chamber 112 and transmits it to the heating element 810; the heating element 810 is conductively connected to the battery 200 of the low temperature resistant power supply device 700 to generate aerosol, which is output to the outlet 115 through the outlet channel 114. Exemplarily, the low temperature resistant aerosol generating device 900 also includes an air flow sensor to control the working state of the heating element 810. In one embodiment, as shown in FIG. 17, an electrode 180 is provided on the control circuit board 140, the battery 200 is conductively connected to the electrode 180 through a first conductive line 191, the heating element 120 is conductively connected to the control circuit board 140 through a second conductive line 192, and the heating element 810 is conductively connected to the control circuit board 140 or the electrode 180 through a third conductive line 193. With such a structural design, the present application proposes a low-temperature resistant aerosol generating device 900 that can heat the battery 200. When the ambient temperature is too low, a separate heating element 120 is added to heat the battery cavity 111 to increase the temperature inside the battery cavity 111, so that the working environment of the battery 200 is within the normal temperature range, thereby avoiding performance degradation and discharge capacity reduction caused by low temperature.

[0061] Continuing with Figures 1 to 17, the low-temperature resistant power supply component 100, the low-temperature resistant power supply device 700 and the low-temperature resistant aerosol generating device 900 are illustrated. It can be understood that in each embodiment, the low-temperature resistant power supply component 100 can also be called a power supply component, the low-temperature resistant power supply device 700 can also be called a power supply device, and the low-temperature resistant aerosol generating device 900 can also be called an aerosol generating device. The remaining embodiments are similar and will not be elaborated on.

[0062] In one embodiment, a low temperature resistant power supply assembly 100 capable of heating a battery 200 includes a housing 110 and a heating element 120. The housing 110 is provided with a battery cavity 111 for placing the battery 200. The heating element 120 is electrically connected to the battery 200 to provide heat at a first output power. The heating element 120 is disposed in the battery cavity 111 and at the periphery of the battery 200, so that the heat generated by the heating element 120 when working can be conducted to the surrounding air of the battery 200 in the battery cavity 111.

[0063] In one embodiment, the heating element 120 is disposed in the battery cavity 111, and the temperature in the battery cavity 111 is increased by directly heating the air in the battery cavity 111. The heating element 120 can be disposed around the battery 200, and has an opening 123 at one end of the C-shaped shape to avoid short circuit; the inner surface 121 of the heating element 120 is spaced apart from the battery 200, and the outer surface 122 of the heating element 120 is spaced apart from the housing 110 to avoid contact with the housing 110 or the battery 200, causing damage to the components and safety risks. As shown in FIG11, the heating element 120 is disposed around the outer surface 122 of the battery 200 at a relatively small angle; in contrast, as shown in FIG12, the heating element 120 is disposed around the outer surface 122 of the battery 200 at a relatively large angle, and different angles can be selected according to cost and actual needs.

[0064] In one embodiment, the low temperature resistant power supply assembly 100 further includes a heat conductor 130, which is disposed between the heating element 120 and the battery 200 and in contact with the inner surface 121 of the heating element 120, or the heating element 120 is embedded in the outer surface 122 of the heat conductor 130; or the heating element 120 is disposed inside the heat conductor 130. The purpose of providing the heat conductor 130 is to allow the heat conductor 130 to surround the battery 200 at a larger angle, such as directly surrounding it in a 360° columnar shape, and also to ensure a longer heating interval in the length direction 300, such as the longitudinal length. The heating element 120, i.e., the heating element, can be a heating wire, a heating net, or a heating sheet. Considering the cost and energy loss of the battery 200, using an overly large heating element 120 for heating will result in excessive battery energy loss. Therefore, the heating effect of the internal environment of the battery cavity 111 can be enhanced by providing the heat conductor 130.

[0065] As shown in FIG13 , the inner surface 121 of the heat conductive member 130 is in contact with the outer surface 122 of the battery 200; in contrast, as shown in FIG14 , the inner surface 121 of the heat conductive member 130 is spaced from the outer surface 122 of the battery 200. The embodiment shown in FIG13 has a relatively better heat conduction effect, while the embodiment shown in FIG14 has a relatively poor heat conduction effect but is beneficial for protecting the battery 200. This is because the battery 200 itself is not suitable for high temperatures. Therefore, whether to contact or not can be selected according to actual conditions, for example, according to the material of the heat conductive member 130, the size of the battery cavity 111, the amount of heat generated by the heating element 120, etc., the embodiment shown in FIG13 or FIG14 can be selected.

[0066] In one embodiment, the heat conductive member 130 is an insulating heat conductive material and is located in the battery cavity 111 so that the heat generated by the heating element 120 can be transferred to the battery cavity 111 through the heat conductive member 130 to increase the ambient temperature of the battery 200 .

[0067] In one of the embodiments, the heat conductor 130 is a heat-conducting material, and an insulating layer 170 is also provided between the heat conductor 130 and the heating element, so that the heat conductor 130 and the heating element are not electrically connected but heat transfer can be achieved. The purpose of avoiding electrical connection is to prevent the heat conductor 130 from electrically contacting the battery 200, causing damage to the battery 200, or to avoid corrosion or oxidation caused by long-term power supply of the conductive element. As shown in Figure 15, an embodiment of adding an insulating layer 170 between the heating element 120 and the heat conductor 130 avoids the risk of short circuit in the battery 200. The insulating layer 170 can be provided independently, or it can be formed integrally with the heating element 120 or the heat conductor 130, or it can be directly a coated insulating material layer.

[0068] In one embodiment, the heat conductor 130 can also be arranged around the battery 200. Since the heat conductor 130 is made of insulating material or an insulating layer 170 is arranged between the heat conductor 130, the heat conductor 130 can be separated from the battery 200 to heat the air in the cavity, or it can be in contact with the battery 200 to achieve direct heat conduction. The heat conductor 130 can also surround the heating element 120. As shown in Figure 16, the heating element 120 is directly arranged inside the heat conductor 130; in one embodiment, the heat conductor 130 is an insulating heat-conducting material, and inorganic non-metallic materials such as glass, rubber, plastic or ceramic can be selected. High thermal conductivity insulating organic materials such as thermal conductive silicone grease can also be selected. The heat-resistant, heat-conductive and insulating properties of the heat conductor 130 are mainly used to effectively realize the heat conduction from the heating element 120 to the battery cavity 111 or the battery 200 through the heat conductor 130, avoiding the problem that the temperature of the battery 200 is too low in a low temperature environment, affecting its performance and capacity.

[0069] In one embodiment, the low temperature resistant power supply assembly 100 is provided with a control circuit board 140 , and the control circuit board 140 is connected to the heating element 120 , and the control circuit board 140 drives the heating element 120 to work.

[0070] In one embodiment, the low temperature resistant power supply component 100 is further provided with a switch component 150, and the switch component 150 is electrically connected to the control circuit board 140 and the heating element 120 respectively to realize the control of the operation and stop of the heating element 120.

[0071] In one embodiment, a temperature measuring component 160 may be further provided in the battery cavity 111 to detect the real-time temperature in the battery cavity 111, and the temperature measuring component 160 is connected to the control circuit board 140. When the switch component 150 is in an open state, that is, the heating element 120 is in a working state, the temperature measuring component 160 detects the temperature in the battery cavity 111, and sends a low temperature signal when it is lower than a first preset value. When the control circuit board 140 receives the low temperature signal, it drives the heating element 120 to work at a first output power. Further, when it is detected that the temperature in the battery cavity 111 reaches a higher second preset value, the heating element 120 is controlled to stop working or work at a lower second output power.

[0072] As shown in FIG5 , the heat conductor 130 is disposed between the heating element 120 and the battery 200, and the heating element 120 covers part of the surface of the heat conductor 130. This embodiment is provided with a temperature measuring component 160 to detect the temperature in the battery cavity 111 or the temperature of the battery 200 itself, and to drive the heating element 120 to work and increase the temperature when the temperature is too low. A switch component 150 is also provided, and the switch component 150 can be a button, and the output operation of the heating element 120 can be controlled by pressing; the switch component 150 can also be a slidable switch to control the output operation of the heating element 120 when it is moved to a specific position. In the embodiment shown in FIG5 , the heating element 120 is disposed on both sides of the battery 200; in contrast, in the embodiment shown in FIG3 , the heating element 120 is disposed on one side of the battery 200.

[0073] In one embodiment, a low-temperature resistant aerosol generating device 900 includes a low-temperature resistant power supply device 700 and an aerosol generating component 800, wherein the aerosol generating component 800 is provided with a liquid storage chamber 112 for storing an aerosol generating medium, and an aerosol generating component 800 connected to the liquid storage chamber 112, wherein the aerosol generating component 800 is electrically connected to the battery 200 and operates to heat and atomize the absorbed aerosol generating medium to generate an aerosol. Exemplarily, the aerosol generating medium may be referred to as an atomizing medium. Exemplarily, relative to the first output power and the second output power, the aerosol generating component 800 operates at a third output power, and the third output power is greater than the first output power, that is, the atomization temperature of the aerosol generating component 800 is greater than the temperature in the battery chamber 111.

[0074] Such a design, by setting a heating element 120 in the power supply device, increases the temperature in the battery cavity 111 through heat conduction, thereby preventing the performance degradation of the battery 200 in a low temperature environment from affecting the normal product experience and the shortening of the usage time due to the reduction of the battery 200 capacity.

[0075] The sol generating component 800 and the low temperature resistant power supply device 700 are assembled as shown in FIG17 . The two may also be an integrated structure. The battery 200 is electrically connected to the aerosol generating component 800, the heating element 120, etc. through conductive circuits such as the first conductive circuit 191, the second conductive circuit 192 and the third conductive circuit 193 to provide electrical energy. The low temperature resistant power supply device 700 is provided with a control circuit board 140 to realize output control of the aerosol generating component 800 and the heating element 120.

[0076] It should be noted that other embodiments of the present application also include low-temperature resistant power supply components, low-temperature resistant power supply devices and low-temperature resistant aerosol generating devices that can be implemented by combining the technical features in the above-mentioned embodiments.
