This condensate can easily flow out of the aerosol generating device from the containment chamber along the air intake channel, causing oil leakage and resulting in a poor user experience.

[0006] In one embodiment, the mounting assembly is further provided with a flow guiding cavity, which is located at the end of the receiving cavity away from the insertion port. The air intake channel is connected to the end of the flow guiding cavity near the receiving cavity, and the liquid collection cavity is connected to the end of the flow guiding cavity away from the receiving cavity.

[0007] In one embodiment, the inner wall surface of the flow guiding cavity away from the receiving cavity is a first inclined surface, the shortest distance between the side of the first inclined surface near the liquid collecting cavity and the receiving cavity is a first distance, and the shortest distance between the side of the first inclined surface away from the liquid collecting cavity and the receiving cavity is a second distance, and the first distance is greater than the second distance.

[0008] In one embodiment, the cavity wall on the side of the flow guide cavity away from the receiving cavity is configured as an elastic film. The elastic film has a first inclined surface. The side of the elastic film away from the receiving cavity is provided with a receiving cavity. The aerosol generating device also includes an airflow sensor. The airflow sensor is disposed in the receiving cavity. The deformation of the elastic film can change the volume of the receiving cavity. The airflow sensor is used to sense the air pressure change in the receiving cavity.

[0009] In one embodiment, the liquid collection chamber surrounds the outer periphery of the receiving chamber and is spaced apart from the receiving chamber. A liquid discharge hole is provided on the side of the first inclined surface away from the axis of the guiding chamber, and the liquid discharge hole is used to connect the guiding chamber and the liquid collection chamber.

[0010] In one embodiment, the mounting assembly includes a bracket assembly and a sealing assembly. The bracket assembly has a receiving cavity and an air inlet channel, and the sealing assembly has a liquid collection cavity. The sealing assembly is sealed to the end of the bracket assembly away from the socket.

[0011] In one embodiment, the sealing assembly includes an elastic element with a mounting groove on the side near the bracket assembly. An annular sealing portion is provided on the sidewall of the mounting groove. One end of the bracket assembly is fitted into the mounting groove and connected to the elastic element through the sealing portion via an interference fit.

[0012] In one embodiment, the bracket assembly includes a bracket and a base. The bracket has a mounting cavity, the base and a heating element are disposed in the mounting cavity, and the base supports the heating element. The heating element and the base cooperate to define a receiving cavity. The cavity wall of the mounting cavity cooperates with the heating element and the base to define an air intake channel. The base is provided with an air intake hole that connects the receiving cavity and the air intake channel.

[0013] In one embodiment, the base has a second slope on the side away from the socket, the second slope being inclined from one side of the air inlet toward one side of the receiving cavity to guide the airflow in the air inlet to the receiving cavity.

[0014] In one embodiment, the support assembly further includes a clamping member mounted on the support. The clamping member has a through hole that is disposed opposite to the receiving cavity.

The air inlet channel is located on the side of the liquid collection cavity near the socket and communicates with the receiving cavity. This application provides a liquid collection chamber connected to the receiving cavity at the end of the receiving cavity away from the insertion port. During suction, the condensate generated in the receiving cavity can flow into the liquid collection chamber. When the aerosol generating device is inverted, the condensate in the liquid collection chamber can be discharged from the aerosol generating device along the receiving cavity. In addition, since the air inlet channel is located on the side of the liquid collection chamber near the insertion port, during suction, the condensate will be collected at the bottom of the liquid collection chamber under the action of gravity, and is not likely to enter the air inlet channel at the top of the liquid collection chamber. Therefore, it avoids the problem of condensate flowing out of the aerosol generating device along the air inlet channel and causing oil leakage, thus improving the user experience.

Therefore, they should not be construed as limitations on the embodiments of this application.

[0026] Please refer to Figure 1-3 This application provides an aerosol generating apparatus, which includes an installation assembly 10 and a heating element 20.

[0027] The mounting assembly 10 includes a receiving cavity 11, an air inlet channel 12, and a liquid collection cavity 13. One end of the receiving cavity 11 has a socket 111 for inserting the aerosol matrix 30 into it. Specifically, when the aerosol generating device is in use, the socket 111 is positioned above the receiving cavity 11 to facilitate insertion of the aerosol matrix 30 into it. A heating element 20 is mounted on the mounting assembly 10 and is used to heat the aerosol matrix 30. In some embodiments, the heating element 20 may form the receiving cavity 11 independently, or the mounting assembly 10 may form the receiving cavity 11 independently, or the heating element 20 may cooperate with the mounting assembly 10 to form the receiving cavity 11. The heating method of the heating element 20 is not limited; for example, it may be resistance heating, electromagnetic induction heating, infrared heating, microwave heating, ultrasonic heating, etc.

[0028] The aerosol matrix 30 includes at least a matrix segment, which is used to generate aerosols upon heating. Therefore, after the aerosol matrix 30 is inserted into the aerosol generating device, at least the matrix segment is located within the receiving cavity 11 to facilitate heating of the matrix segment by the heating element 20. In one embodiment, the aerosol matrix 30 further includes a coating layer that surrounds the matrix segment. The matrix segment is primarily composed of tobacco, herbal or plant leaves, or medicinal materials. It is understood that the materials forming the matrix segment are not limited; the matrix segment can be formed from a single material or from a mixture of multiple materials in different proportions.

[0029] The coating layer can be formed of a coating material such as paper, thereby maintaining the shape of the matrix segment. The material forming the coating layer is not limited to this; in other embodiments, the coating layer can also be formed of other materials such as aluminum foil to meet different requirements. In one embodiment, the aerosol matrix 30 further includes a nozzle segment, a cooling segment, and a sealing segment, which are arranged sequentially along the axis of the matrix segment. The nozzle segment mainly has a filtering function, through which the user inhales the aerosol. The nozzle segment may contain a filter medium that can filter tar, suspended particles, etc., in the aerosol, thereby reducing unwanted substances in the aerosol inhaled by the user. The filter medium can be, for example, a polylactic acid filament tow or a cellulose acetate filament tow. The main function of the cooling segment is to lower the temperature of the aerosol to prevent burns to the mouth. The cooling segment has a cooling channel, and the inner wall of the cooling channel has cooling holes communicating with the outside of the cooling segment. After being generated in the matrix section, the aerosol flows through the cooling channel and finally exits from the nozzle section for the user to inhale. As the aerosol passes through the cooling channel, cold air can enter the cooling channel through the cooling holes under negative pressure to mix with the aerosol and lower its temperature.

[0030] The cooling section can be made of one of the following materials: polylactic acid / aluminum foil composite film, paper filter rod, polylactic acid nonwoven fabric, polylactic acid granules, polylactic acid filament braided tube, serrated polylactic acid folded film, cellulose acetate, or cooling activated carbon composite material. The sealing section is located at the end of the aerosol matrix 30 and provides a physical support base to prevent the particles or materials of the aerosol matrix 30 from loosening or falling off during heating, maintaining the integrity of the aerosol matrix 30. This avoids leakage due to thermal expansion or movement of the matrix section, which would affect the user experience. The sealing section generally allows gas to pass through, facilitating airflow from the bottom of the aerosol matrix 30 into the matrix section. Furthermore, if condensate is generated in the cooling section or matrix section, the fiber structure of the sealing section can prevent the liquid from flowing out of the aerosol matrix 30. Additionally, the sealing section can control airflow resistance through fiber density to ensure smooth suction. Materials for the sealing section include, for example, polypropylene fiber, polyester fiber, cotton, and cellulose acetate. In other embodiments, the aerosol matrix 30 may not have at least one of the cooling section, sealing section, and nozzle section, or the aerosol matrix 30 may have other functional sections, which will not be described in detail here.

[0031] Please refer to Figure 2 , Figure 2 The arrows inside indicate the direction of liquid flow. The collection chamber 13 is located at the end of the receiving chamber 11 away from the inlet 111 and is connected to the receiving chamber 11. It is used to collect condensate. During suction, the inlet 111 is oriented above the receiving chamber 11. Since the collection chamber 13 is located below the receiving chamber 11, the condensate easily flows from the receiving chamber 11 to the collection chamber 13 below the receiving chamber 11 under the action of gravity. After suction is completed, the aerosol matrix 30 is removed from the receiving chamber 11. Since the inlet 111 is connected to the outside of the aerosol generating device, after the aerosol generating device is inverted, the condensate will flow from the collection chamber 13 to the receiving chamber 11 under the action of gravity. Finally, the aerosol generating device is poured out from the inlet 111 of the receiving chamber 11. This method of handling condensate is relatively fast and convenient.

[0032] Please refer to Figure 3 , Figure 3 The arrows inside indicate the direction of gas flow. The air intake channel 12 is located on the side of the liquid collection chamber 13 near the inlet 111 and communicates with the receiving chamber 11. In some embodiments, the air intake channel 12 is arranged around the outer periphery of the receiving chamber 11. During suction, the air intake channel 12 is located above the liquid collection chamber 13. Under gravity, the condensate will collect at the bottom of the liquid collection chamber 13, making it less likely to enter the air intake channel 12 at the top of the liquid collection chamber 13. This avoids the problem of condensate flowing out of the aerosol generating device along the air intake channel, causing oil leakage and improving the user experience.

[0033] In one embodiment, please refer to Figure 2 and Figure 3The mounting assembly 10 also includes a flow guiding cavity 14, located at the end of the receiving cavity 11 away from the insertion port 111. Both the air intake channel 12 and the liquid collection cavity 13 are connected to the receiving cavity 11 via the flow guiding cavity 14. Specifically, the air intake channel 12 is connected to the end of the flow guiding cavity 14 closest to the receiving cavity 11, and the liquid collection cavity 13 is connected to the end of the flow guiding cavity 14 away from the receiving cavity 11. Thus, condensate can flow from the receiving cavity 11 through the bottom wall of the flow guiding cavity 14 to the liquid collection cavity 13, and airflow can flow from the air intake channel 12 through the upper side of the flow guiding cavity 14 to the receiving cavity 11. The flow guiding cavity 14 can guide both liquid and gas, and the airflow path and liquid path are different, preventing mutual interference between the liquid and gas.

[0034] In one embodiment, such as Figure 2 As shown, the inner wall surface of the flow guiding cavity 14 away from the receiving cavity 11 is a first inclined surface 141. The first inclined surface 141 is used to guide the liquid in the flow guiding cavity 14 to the liquid collecting cavity 13. Specifically, the first inclined surface 141 can be a plane, a curved surface, or a folded surface. The shortest distance between the side of the first inclined surface 141 near the liquid collecting cavity 13 and the receiving cavity 11 is the first distance, and the shortest distance between the side of the first inclined surface 141 away from the liquid collecting cavity 13 and the receiving cavity 11 is the second distance. The first distance is greater than the second distance, that is, the side of the first inclined surface 141 away from the liquid collecting cavity 13 is higher, and the side of the first inclined surface 141 near the liquid collecting cavity 13 is lower. Thus, under the action of gravity and the first inclined surface 141, the condensate can flow from the higher part of the first inclined surface 141 to the lower part, and then flow into the liquid collecting cavity 13.

[0035] In one embodiment, the cavity wall of the guide cavity 14 away from the receiving cavity 11 is configured as an elastic film 142. The elastic film 142 has a first inclined surface 141. A receiving cavity 15 is provided on the side of the elastic film 142 away from the receiving cavity 11. The aerosol generating device also includes an airflow sensor (not shown), which may be, for example, a microphone or silicone microphone. The airflow sensor is located in the receiving cavity 15 and is used to sense changes in air pressure within the receiving cavity 15. During suction, since the gas in the air intake channel 12 needs to flow through the guide cavity 14 to the receiving cavity 11, the air pressure in the guide cavity 14 will change during suction. Under the action of air pressure, the elastic film 142 is prone to deformation. The deformation of the elastic film 142 can change the volume of the receiving cavity 15. The airflow sensor is used to sense the changes in air pressure within the receiving cavity 15 and send a corresponding signal to the controller. Thus, the controller can know the user's suction action and perform subsequent control. Since the airflow sensor is located in a relatively enclosed cavity 15, while the airflow sensor can perform the suction action, the elastic diaphragm 142 can separate the condensate from the airflow sensor, thus preventing the condensate from flowing into the airflow sensor and causing damage to the airflow sensor.

[0036] Preferably, the liquid collecting chamber 13 is arranged around the outer periphery of the receiving cavity 15 and spaced apart from the receiving cavity 15. A drain hole 143 is provided on the side of the first inclined surface 141 away from the axis of the guiding cavity 14, which connects the guiding cavity 14 and the liquid collecting chamber 13. The shortest distance between the side of the first inclined surface 141 near the axis of the guiding cavity 14 and the receiving cavity 11 is less than the shortest distance between the side of the first inclined surface 141 away from the axis of the guiding cavity 14 and the receiving cavity 11. The liquid collecting chamber 13 is connected to the side of the guiding cavity 14 away from the axis of the guiding cavity 14, meaning the middle part of the first inclined surface 141 is high and the outer periphery of the first inclined surface 141 is low, so that the first inclined surface 141 can guide the condensate to the liquid collecting chamber 13 on the outer periphery of the receiving cavity 15. The drain hole 143 can be annular, or there can be multiple drain holes 143 arranged along the circumferential direction of the guiding cavity 14. Of course, in other embodiments, the liquid collection chamber 13 may be located directly below the flow guiding chamber 14, and the receiving chamber 15 may be located to the side of the flow guiding chamber 14.

[0037] In one embodiment, please refer to Figure 2 and Figure 3 The mounting assembly 10 includes a bracket assembly 16 and a sealing assembly 17. The bracket assembly 16 has a receiving cavity 11 and an air inlet channel 12. The sealing assembly 17 has a liquid collection cavity 13. The sealing assembly 17 is sealed to the end of the bracket assembly 16 away from the inlet 111. The sealing connection can be achieved by a sealing ring, or the connection between the sealing assembly 17 and the bracket assembly 16 can be an elastic structure with a sealing part 1712, which seals the sealing assembly 17 and the bracket assembly 16. The sealing assembly 17 and the bracket assembly 16 cooperate to form a flow guiding cavity 14. By using the sealing assembly 17 to seal the end of the bracket assembly 16 away from the inlet 111, leakage of liquid and gas can be prevented on the side of the bracket assembly 16 away from the inlet 111, and condensate can be prevented from flowing onto other components of the aerosol generating device.

[0038] In one embodiment, such as Figure 2 and Figure 4As shown, the sealing assembly 17 includes an elastic element 171 and a mounting element 172. The elastic element 171 can be made of silicone material, for example. The elastic element 171 has a mounting groove 1711 on the side near the support assembly 16. An annular sealing portion 1712 is provided on the side wall of the mounting groove 1711. One end of the support assembly 16 is fitted into the mounting groove 1711 and connected to the elastic element 171 via the sealing portion 1712 through an interference fit. A slot 1713 is formed on the bottom wall of the mounting groove 1711. When the support assembly 16 is fitted onto the mounting groove 1711, the support assembly 16 and the slot 1713 cooperate to form a flow guiding cavity 14, and the bottom wall of the slot 1713 is configured as an elastic membrane 142. The mounting element 172 is connected to the side of the elastic element 171 away from the support assembly 16, and the mounting element 172 and the elastic element 171 cooperate to form a liquid collecting cavity 13 and a receiving cavity 15. By providing the elastic element 171 and the mounting element 172, on the one hand, the elastic element 171 can be used to seal the bracket assembly 16, and the elastic element 171 facilitates the production of the elastic film 142 by means of a mold. On the other hand, it facilitates the installation of the airflow sensor in the accommodating cavity 15.

[0039] In one embodiment, such as Figure 3 and Figure 5 As shown, the bracket assembly 16 includes a bracket 161 and a base 162. The bracket 161 has a mounting cavity 1611. The base 162 and the heating element 20 are disposed within the mounting cavity 1611, and the base 162 supports the heating element 20. The end of the bracket 161 away from the sealing assembly 17 abuts against the heating element 20, thereby fixing the heating element 20. The heating element 20 and the base 162 cooperate to define a receiving cavity 11. The cavity wall of the mounting cavity 1611 cooperates with the heating element 20 and the base 162 to define an air intake channel 12. The base 162 is provided with an air intake hole 1621 communicating with the receiving cavity 11 and the air intake channel 12. Specifically, one end of the air intake hole 1621 communicates with the air intake channel 12, and the other end of the air intake hole 1621 communicates with a guide cavity 14, which communicates with the receiving cavity 11. In this embodiment, the support assembly 16 receives air from the top and flows through the gap between the support 161 and the heating element 20 to the bottom of the support assembly 16, ultimately entering the aerosol matrix 30 within the receiving cavity 11. In other embodiments, the air intake channel 12 may also be located in the gap between the heating element 20 and the aerosol matrix 30, i.e., air enters from the inside of the heating element 20 and the outside of the aerosol matrix 30. The top-intake method of the support assembly 16 effectively prevents condensate from flowing out from the air intake channel 12, and the gas can also be preheated by the heating element 20, making the airflow entering the aerosol matrix 30 a hot airflow. This hot airflow can also heat the aerosol matrix 30, improving energy utilization.

[0040] In one embodiment, please refer to Figure 3The base 162 has a second inclined surface 144 on the side away from the socket 111. The second inclined surface 144 slopes from one side of the air inlet 1621 toward the side of the receiving cavity 11 to guide the airflow in the air inlet 1621 to the receiving cavity 11. The guide cavity 14 also has the second inclined surface 144. When the airflow in the air inlet 1621 flows to the guide cavity 14, it can be guided along the second inclined surface 144 to the receiving cavity 11, facilitating the rapid entry of the airflow into the receiving cavity 11.

[0041] In one embodiment, such as Figure 3 and Figure 5 As shown, the support assembly 16 also includes a clamping member 163, which is mounted on the support 161. The clamping member 163 has a through hole 1631, which is opposite to the receiving cavity 11. The through hole 1631 is used for the aerosol matrix 30 to pass through. A clamping part 1632 is provided on the wall of the through hole 1631 for clamping the aerosol matrix 30. By providing the clamping part 1632 to clamp the aerosol matrix 30, it can be ensured that the aerosol matrix 30 is not easily shaken during the suction process.

[0042] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
