Description

Technical Field

[0001] This application relates to the field of atomization device technology, specifically to an aerosol matrix heating component and an aerosol generation device. Background Technology

[0002] Aerosol generating devices are used to generate aerosols for users to inhale. One current type of aerosol generating device generates aerosols by heating an aerosol generating rod. Specifically, the aerosol generating rod is inserted into the device, and an electric heating element within the device heats the rod to generate aerosols. The electric heating element typically needs to control the temperature while heating the aerosol generating rod to ensure that the materials used to generate the aerosol are produced in a non-combustible state.

[0003] Currently, in the use of aerosol generating devices, the electric heating element typically heats the outer periphery of the aerosol generating rod, resulting in uneven heating. This uneven heating problem can be improved by supplying a hot gas flow to the bottom of the aerosol generating rod.

[0004] Heating the outer periphery of the heat exchanger with an electric heating element allows the airflow to be heated as it passes through the heat exchanger. However, the airflow temperature is higher at the edge of the heat exchanger and lower at the center, resulting in a large temperature difference between the hot airflow in different areas. Consequently, the heat uniformity of the aerosol generating rod is poor after it enters the aerosol generating rod. Utility Model Content

[0005] This application provides an aerosol matrix heating assembly to improve the problem of poor heating uniformity of the current hot airflow to the aerosol generating rod.

[0006] In addition, the purpose of this application is to provide an aerosol generating apparatus that uses the above-mentioned aerosol matrix heating component.

[0007] In a first aspect, one embodiment provides an aerosol matrix heating assembly, the aerosol matrix heating assembly having a receiving cavity for inserting an aerosol generating rod; the aerosol matrix heating assembly includes:

[0008] A heat exchanger having multiple heat exchange channels communicating with the receiving cavity; the heat exchange channels are used to heat the airflow flowing toward the aerosol generating rod;

[0009] A heating element, wherein the heating element is at least used for heating the heat exchanger;

[0010] And a flow divider, which is located in the gas passage between the receiving cavity and the heat exchanger; the flow divider has at least two gas equalization spaces and a barrier structure separating adjacent gas equalization spaces on the side facing the heat exchanger;

[0011] The heat exchange channel includes a central heat exchange channel and an edge heat exchange channel. The central heat exchange channel is located in the middle of the heat exchanger, and the edge heat exchange channel is located at the edge of the heat exchanger. The same gas distribution space is simultaneously connected to the central heat exchange channel and the edge heat exchange channel. The distributor has an outlet that is connected to the gas distribution space and is used to supply gas to the aerosol generating rod.

[0012] In a further embodiment, the barrier structure includes partition strips extending from the center of the distributor to the edge, with each partition strip being radially distributed; adjacent air distribution spaces along the circumference of the distributor are separated by the partition strips.

[0013] In another embodiment, the vent is located near the edge of the splitter and away from the center of the splitter.

[0014] Furthermore, in one embodiment, the flow area of ​​the air outlet is smaller than the flow area of ​​the uniform air space.

[0015] Furthermore, in one embodiment, each of the gas equalization spaces is arranged circumferentially along the distributor.

[0016] Furthermore, in one embodiment, the distributor has a confluence space on the side facing the receiving cavity, and each of the air outlets is connected to the confluence space.

[0017] In a further embodiment, the diverter includes a diverter base and a protrusion on the side of the diverter base facing the receiving cavity. The protrusion is used to block the end face of the aerosol generating rod that is inserted into the receiving cavity, so as to prevent the aerosol generating rod from entering the confluence space.

[0018] Furthermore, in one embodiment, the air outlet corresponds one-to-one with the air distribution space.

[0019] In a further embodiment, the heating element is a heating tube, which includes a heat exchanger heating section and a generating rod heating section. The heat exchanger heating section and the generating rod heating section are arranged axially on the heating tube. At least a portion of the heat exchanger is located in the heat exchanger heating section and is in thermally conductive contact with the heat exchanger heating section, so that the heat exchanger heating section heats the heat exchanger. The generating rod heating section forms at least a portion of the receiving cavity.

[0020] In a second aspect, one embodiment provides an aerosol generating apparatus, including a housing and an aerosol matrix heating assembly as described in any embodiment of the first aspect, wherein the aerosol matrix heating assembly is mounted on the housing.

[0021] According to the aerosol matrix heating assembly of the above embodiment, the distributor of the aerosol matrix heating assembly is located in the gas passage between the receiving cavity and the heat exchanger. The airflow heated by the heat exchanger is split by the distributor before entering the aerosol generating rod. Since the same gas equalization space in the distributor is connected to both the central heat exchange channel and the edge heat exchange channel, the temperature difference of the airflow in different areas can be reduced through the gas equalization space. The separation of multiple gas equalization spaces can reduce the airflow crosstalk between different gas equalization spaces, making the low temperature airflow and the high temperature airflow mix more evenly, thereby making the temperature difference of the airflow entering the aerosol generating rod smaller, and improving the current problem of poor heating uniformity of the hot airflow to the aerosol generating rod.

For example, different implementation methods can be formed by combining different embodiments. In order to avoid unnecessary repetition, the various possible combinations of the embodiments will not be described separately.

[0036] To address the problem of poor heating uniformity in current aerosol generating rods, the aerosol matrix heating assembly of this application uses a distributor to divert the airflow from the heat exchanger. This allows the airflow heated in the central heat exchange channel and the airflow heated in the edge heat exchange channels to enter the same uniform gas space. Within this uniform gas space, the temperature difference of the airflow is reduced, resulting in more uniform airflow temperature. This more uniformly heated airflow exits from the outlet and enters the aerosol generating rod, thus ensuring more even heating of the aerosol generating rod. The aerosol matrix heating assembly of this application will be described in detail below with reference to the accompanying drawings.

[0037] First, the object being heated by the aerosol matrix heating component, namely the aerosol generating rod 1, will be explained. Please refer to [link / reference needed]. Figures 1 to 3The aerosol generating rod 1 has a suction end 11 for drawing in aerosols at one end and an air inlet end 12 at the other end, which supplies gas into the aerosol generating rod 1 during suction. The suction end 11 has a filter (not shown in the figure). The filter (not shown in the figure) can be made of various existing or future feasible materials, such as sponge, cigarette holder paper, etc. The aerosol generating rod 1 contains an aerosol matrix, and the suction end 11 of the aerosol generating rod 1 has filter cotton. The aerosol matrix is ​​an aerosol filament or aerosol sheet used to generate aerosols. In some embodiments, the aerosol matrix is ​​a heat-non-combustible matrix, meaning that it can generate aerosols in a non-combustible state after heating.

[0038] In one embodiment, please refer to Figures 3 to 5 The aerosol matrix heating assembly has a receiving cavity 2 into which the aerosol generating rod 1 is inserted. The aerosol matrix heating assembly includes a heat exchanger 3, a heating element 4, and a flow divider 5. The heating element 4 is used to heat at least the heat exchanger 3. The heat exchanger 3 has multiple heat exchange channels 31, which communicate with the receiving cavity 2 and are used to heat the gas flow entering the aerosol generating rod 1. The heat exchange channels 31 include a central heat exchange channel 311 and an edge heat exchange channel 312, wherein the central heat exchange channel 311 is located in the middle of the heat exchanger 3, and the edge heat exchange channel 312 is located at the edge of the heat exchanger 3.

[0039] The distributor 5 is located in the gas passage between the housing cavity 2 and the heat exchanger 3. The distributor 5 has at least two gas equalization spaces 51 and a barrier structure 52 separating adjacent gas equalization spaces 51 on the side facing the heat exchanger 3. In this way, the airflow crosstalk between different gas equalization spaces 51 can be reduced by the barrier structure 52.

[0040] The same uniform gas space 51 is simultaneously connected to the central heat exchange channel 311 and the edge heat exchange channel 312. This allows the airflow heated by the central heat exchange channel 311 and the airflow heated by the edge heat exchange channel 312 to mix in the uniform gas space 51, resulting in a more uniform temperature of the mixed hot airflow. The distributor 5 has an outlet 53 connected to the uniform gas space 51. The airflow entering the uniform gas space 51 flows out through the outlet 53 and supplies gas to the aerosol generating rod 1.

[0041] After being heated by heat exchanger 3, the airflow is split by splitter 5 before entering aerosol generating rod 1. Since the same uniform gas space 51 in splitter 5 is connected to both the central heat exchange channel 311 and the edge heat exchange channel 312, the temperature difference of the airflow in different areas can be reduced through uniform gas space 51, thereby making the temperature difference of the airflow entering aerosol generating rod 1 smaller and improving the problem of poor heating uniformity of the current hot airflow to aerosol generating rod 1.

[0042] It should be noted that the separation of adjacent gas-uniforming spaces 51 in this application includes not only cases where adjacent gas-uniforming spaces 51 are completely separated and not connected, but also cases where the gas-uniforming spaces 51 are connected. For example, if a gas-uniforming space 51 is located in a groove, and two adjacent gas-uniforming spaces 51 are located in two separate grooves, with the openings of the two adjacent grooves facing the same direction and communicating with each other, the groove walls between the two grooves can prevent the gas flow between adjacent gas-uniforming spaces 51. In other words, when adjacent gas-uniforming spaces 51 are separated by the blocking structure 52, the blocking structure 52 can block the gas flow between the gas-uniforming spaces 51. This blocking effect can either prevent the gas from flowing between adjacent gas-uniforming spaces 51, or it can only block part of the gas flow.

[0043] In one embodiment, the heating element 4 can not only heat the heat exchanger 3, but also simultaneously contact the aerosol generating rod 1 to heat the aerosol generating rod 1. Of course, in some other embodiments, the heating element 4 may only heat the heat exchanger 3.

[0044] Furthermore, in one embodiment, please refer to Figures 3 to 5 The vent 53 is located near the edge of the distributor 5 and away from the center of the distributor 5. This way, the vent 53 faces the edge of the aerosol generating rod 1 and is less likely to be blocked. In some other embodiments, the vent 53 may also be located away from the edge of the distributor 5 and near the center of the distributor 5.

[0045] In one embodiment, please refer to Figure 4 Each air distribution space 51 is arranged circumferentially along the distributor 5. Specifically, in one embodiment, the distributor 5 includes dividing strips 54 extending from the center of the distributor 5 to the edge, with each dividing strip 54 radially distributed, separating adjacent air distribution spaces 51. The radial distribution of the dividing strips 54 enables a more uniform airflow distribution. In some other embodiments, the dividing strips 54 can also adopt other arrangements, such as the air distribution spaces 51 being elongated strips, with each air distribution space 51 arranged linearly.

[0046] Specifically, in one embodiment, please refer to Figures 3 to 5 The distributor 5 includes a distributor base 55, and a partition strip 54 is integrally formed with the distributor base 55. The partition strip 54 is located on the side of the distributor base 55 facing the heat exchanger 3. In some other embodiments, the partition strip 54 may also be fixed to the distributor base 55 by welding, snap-fitting, or fasteners.

[0047] In one embodiment, please refer to Figure 3 and Figure 4In order to make the low-temperature airflow and the high-temperature airflow mix more evenly, the flow area of ​​the air outlet 53 is smaller than that of the uniform air space 51. This way, the airflows of different temperatures in the uniform air space 51 can mix more fully when passing through the air outlet 53.

[0048] In one embodiment, please refer to Figure 3 and Figure 5 The distributor 5 has a confluence space 56 on the side facing the receiving cavity 2, and each air outlet 53 is connected to the confluence space 56. The confluence space 56 allows the gases flowing out of each air outlet 53 to mix again, further improving the problem of uneven gas temperature entering the aerosol generating rod 1. In some other embodiments, the openings of the air outlets 53 can also be directly attached to the end face of the aerosol generating rod 1, and the airflow directly enters the aerosol generating rod 1 after flowing out of the air outlets 53.

[0049] In one embodiment, please refer to Figures 3 to 5 The air outlet 53 corresponds one-to-one with the air distribution space 51, which allows the airflow in the air distribution space 51 to flow out from the same air outlet 53, further improving the uniformity of the airflow temperature. In some other embodiments, one air distribution space 51 may also correspond to two air outlets 53.

[0050] In one embodiment, please refer to Figures 3 to 5 The diverter 5 includes a protrusion 57 on the diverter base 55 facing the receiving cavity 2. The protrusion 57 blocks the end face of the aerosol generating rod 1 inserted into the receiving cavity 2, preventing the aerosol generating rod 1 from entering the confluence space 56. The protrusion 57 limits the insertion depth of the aerosol generating rod 1, allowing the aerosols from the outlets 53 to mix again in the confluence space 56. Specifically, in one embodiment, the protrusion 57 is located at the edge of the diverter base 55, extending in an arc shape along the edge of the diverter base 55. In some other embodiments, the protrusion 57 may also be located in the middle of the diverter base 55.

[0051] In one embodiment, please refer to Figure 3The heating element 4 is a heating tube 40, which includes a heat exchanger heating section 41 and a generating rod heating section 42. The heat exchanger heating section 41 and the generating rod heating section 42 are arranged axially in the heating tube 40. At least a portion of the heat exchanger 3 is located in the heat exchanger heating section 41 and is in thermal contact with the heat exchanger heating section 41, so that the heat exchanger heating section 41 heats the heat exchanger 3. The generating rod heating section 42 forms at least a portion of the receiving cavity 2. The generating rod heating section 42 can directly heat the aerosol generating rod 1, improving heating efficiency. In addition, the outer periphery of the aerosol generating rod 1 dissipates heat quickly, and heating the outer periphery of the aerosol generating rod 1 can reduce the temperature difference between the outer periphery and the center of the aerosol generating rod 1. In one embodiment, the heat exchanger 3 is interference-fitted into the heating tube 40. Of course, the heat exchanger 3 can also be fixed by welding, snap-fitting, or other methods. The heat exchanger 3 and the distributor 5 can also be fixed together by welding, interference fit, snap-fitting, or magnetic attraction.

[0052] Regarding the form of the heating element 40, please refer to one embodiment. Figure 3 The heating element 40 generates heat when energized. The heating element 40 includes a heat-conducting tube body 43 and an electric heating element 44. The electric heating element 44 is disposed on the heat-conducting tube body 43 and in thermal contact with it to transfer the generated heat to the heat-conducting tube body 43 to heat the aerosol generating rod 1. The electric heating element 44 can be of various types, such as a resistive coating or a resistance wire coil; or, for example, a heating film printed on the outer circumferential surface of the heat-conducting tube body 43, in which case the electric heating element 44 and the heat-conducting tube body 43 together form a thick film tube with an insulating layer outside the heating film. In this case, the heat-conducting tube body 43 can be a metal tube with good thermal conductivity; or, for example, the electric heating element 44 can be embedded within the wall of the heat-conducting tube body 43. The electric heating element 44 can be a resistance wire, in which case the heat pipe body 43 is suitable to be made of an insulating and heat-conducting material. Alternatively, an insulating layer can be coated on the outer periphery of the resistance wire, in which case the heat pipe body 43 can also be made of a conductive material. For example, the electric heating element 44 can also be a resistance wire wound on the outer wall of the heat pipe body 43. For example, the electric heating element 44 can be laid on the inner surface of the heat pipe body 43.

[0053] It should be noted that the thermally conductive contact in this application includes both direct contact and indirect contact that can transfer heat. There are various ways of indirect contact, such as applying thermal grease between the electric heating element 44 and the heat-conducting pipe body 43, or adding an insulating layer between the heat-conducting pipe body 43 and the electric heating element 44 to ensure safety.

[0054] To facilitate the installation of the heating element 40, in one embodiment, please refer to... Figure 3The aerosol generating matrix heating assembly includes a first heating tube seat 6 and a second heating tube seat 7. A heating tube 40 is sandwiched between the first heating tube seat 6 and the second heating tube seat 7. The first heating tube seat 6 has a first seat hole through which the aerosol generating rod 1 passes into the insertion receiving cavity 2. The second heating tube seat 7 has a second seat hole through which the airflow entering the aerosol generating rod 1 passes. In one embodiment, the first end of the heating tube 40 is inserted into the first seat hole and is press-fitted with the first seat hole, and the second end is inserted into the second seat hole and is press-fitted with the second seat hole. The first heating tube seat 6 includes a first base 61 and a sheath 62, which are integrally formed. One end of the sheath 62 is connected to the first base 61, and the other end is press-fitted with the second heating tube seat 7. An annular gap 63 is formed between the sheath 62 and the heating tube 40. The annular gap 63 can block heat transfer to the sheath 62, thereby reducing heat leakage.

[0055] In some other embodiments, the heating tube 40 can also be directly fixed to the housing of the aerosol generating device; the first end of the heating tube 40 can also be fixed to the housing of the aerosol generating device, and the second end can be fixed to the second heating tube seat 7, in which case the first heating tube seat 6 is not required.

[0056] In one embodiment of an aerosol generation device, a housing and an aerosol matrix heating assembly as described in any of the above embodiments are included, the aerosol matrix heating assembly being mounted on the housing. In one embodiment, the aerosol generation device further includes a power source for supplying power to the aerosol matrix heating assembly.

[0057] 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.
