Description

Technical Field

[0001] This application relates to the field of atomization technology, and more specifically, to an atomizer and an aerosol generating device. Background Technology

[0002] In the field of atomization technology, aerosol generating devices utilize microwave energy to act on an aerosol generating product loaded within a loading cavity, causing the product to generate aerosols. Specifically, such aerosol generating devices typically include a substrate and an RF power chip, a circulator, and an RF resistor, all mounted on the substrate. The RF power chip generates high-frequency energy, which the circulator unidirectionally transmits to the loading cavity, acting on the aerosol generating product to generate aerosols. When the atomizer is in a state of impedance mismatch, i.e., the impedance of the second terminal is not perfectly matched with the heating element, the circulator directs the high-frequency energy generated by the RF power chip to the RF resistor, thus preventing the RF power chip from continuously generating high-frequency energy that cannot be conducted to the loading component and could damage the RF power chip. However, because the high-frequency energy generated by the RF power chip is applied to the RF resistor, the temperature of the RF resistor rises. The heat from the RF resistor acts on the RF power chip through the substrate, affecting the operating efficiency of the RF power chip and, in severe cases, causing malfunctions in the aerosol generating device. Utility Model Content

The loading member has a loading cavity configured to load an aerosol-generating article. The RF element includes a substrate, an RF power chip, a circulator, and an RF resistor. Both the RF power chip and the circulator are disposed on the substrate. The RF power chip is configured to generate an RF signal. The circulator includes a first end, a second end, and a third end. The first end of the circulator is electrically connected to the RF power chip, the second end of the circulator is electrically connected to the loading member, and the RF resistor is disposed outside the substrate and electrically connected to the third end of the circulator. The circulator is configured to: when the atomizer is in a first state, transmit the RF signal generated by the RF power chip to the loading member through the first and second ends to heat the aerosol-generating article; and when the atomizer is in a second state, transmit the RF signal generated by the RF power chip to the RF resistor through the third end.

[0005] In some embodiments, the radio frequency resistor is disposed on the loading element.

[0006] In some embodiments, the radio frequency (RF) assembly further includes an RF housing connected to the loading member, wherein the substrate, the RF power chip, and the circulator are all disposed within the RF housing. The loading member includes a first side connected to the RF housing, and the RF resistor is disposed on the first side of the loading member and located outside the loading cavity.

[0007] In some embodiments, a groove is provided on the first side of the loading member, and the radio frequency resistor is at least partially housed within the groove.

[0008] In some embodiments, the radio frequency (RF) assembly further includes a first electrical connector. The RF housing includes a first side connected to the loading member and a second side connected to the first side of the RF housing. The first side of the RF housing has an opening, and the second side of the RF housing has a through-hole. The first electrical connector passes sequentially through the through-hole and the opening, and is electrically connected to the third terminal of the circulator and the RF resistor.

[0009] In some embodiments, the radio frequency assembly further includes a second electrical connector. The radio frequency housing includes a first side connected to the loading member and a second side connected to the first side of the radio frequency housing. The first side of the radio frequency housing has an opening, and the second side of the radio frequency housing has a through hole. The second electrical connector passes sequentially through the through hole and the opening, and electrically connects the second end of the circulator to the loading member.

[0010] In some embodiments, the RF housing includes a first housing and a second housing. The second housing is connected to the first housing and forms a receiving cavity. The substrate, the RF power chip, and the circulator are all housed within the receiving cavity.

[0011] In some implementations, the RF power chip is located further away from the RF resistor than the circulator.

[0012] In some embodiments, the radio frequency component further includes a matching circuit. The radio frequency power chip is electrically connected to a first terminal of the circulator via the matching circuit. The matching circuit is configured to match the output impedance of the radio frequency power chip with the input impedance of the circulator.

[0013] Secondly, this application provides an aerosol generating device. The aerosol generating device includes a battery assembly and an atomizer as described in any of the above embodiments, wherein the atomizer is electrically connected to the battery assembly.

[0014] In the atomizer and aerosol generating device of this application, an RF power chip and a circulator are disposed on a substrate, and the RF power chip generates a high-frequency RF signal. An RF resistor is disposed outside the substrate and is not disposed together with the RF power chip. The circulator includes a first terminal, a second terminal, and a third terminal. The signal within the circulator is configured to different transmission paths depending on the atomizer's state. When the atomizer is operating normally, the RF signal generated by the RF power chip is transmitted to the loading component through the first and second terminals to heat the aerosol-generated product. When the atomizer is in a state of imperfect impedance matching, i.e., the second terminal is not perfectly matched to the impedance of the heating element, at least a portion of the RF signal generated by the RF power chip is transmitted to the RF resistor through the third terminal. Because the RF resistor is disposed outside the substrate, the heat generated by the RF resistor is prevented from acting on the RF power chip through the substrate, thus ensuring the RF power chip's operating efficiency and guaranteeing the normal operation of the atomizer and aerosol generating device.

[0029] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0034] In the field of atomization technology, aerosol generating devices can use microwave energy to act on an aerosol generating product loaded in a loading cavity, thereby causing the aerosol generating product to generate aerosol. Specifically, such aerosol generating devices typically include a substrate and an RF power chip, a circulator, and an RF resistor, all mounted on the substrate. The RF power chip generates high-frequency energy, and the circulator unidirectionally transmits the high-frequency energy generated by the RF power chip to the loading cavity, acting on the aerosol generating product within the loading cavity to generate aerosol. When the atomizer is in a state of imperfect impedance matching, i.e., the impedance of the second terminal is not perfectly matched with that of the heating component, the circulator will direct the high-frequency energy generated by the RF power chip to the RF resistor, thereby preventing the RF power chip from continuously generating high-frequency energy that cannot be conducted to the loading component and thus damaging the RF power chip. However, since the high-frequency energy generated by the RF power chip is applied to the RF resistor, it will cause the temperature of the RF resistor to rise. The heat on the RF resistor will act on the RF power chip through the substrate, affecting the working efficiency of the RF power chip, and in severe cases, causing the aerosol generating device to malfunction. To solve this problem, this application provides an atomizer ( Figure 2 (as shown) and aerosol generating device ( Figure 1 (As shown).

[0035] Please refer to Figure 1 The aerosol generating device 100 of this application includes a battery assembly 30 and an atomizer 10, with the atomizer 10 electrically connected to the battery assembly 30.

[0036] The aerosol generating device 100 is a small device capable of heating an aerosol generating article to produce an aerosol. The aerosol generating article is a product that, after processing and heating, can generate an aerosol. The aerosol generating article can be, but is not limited to, liquid, semi-solid, and fully solid. Liquid aerosol generating articles include e-liquid; semi-solid aerosol generating articles include gel-like e-liquid; and fully solid aerosol generating articles include cigarettes. Different forms of aerosol generating articles require the use of a suitable aerosol generating device 100. The aerosol generating article in this application can be liquid, fully solid, or semi-solid, without limitation. Aerosols can be visible or invisible, and can include, but are not limited to, one or more combinations of gaseous substances, liquid droplets, and solid particles. The atomizer 10 is a device in the aerosol generating device 100 used to heat the aerosol generating article and cause the aerosol generating article to generate an aerosol. The heating method for the atomizer 10 to heat the aerosol-generating article can be, but is not limited to, resistance heating, microwave heating, and laser irradiation heating. The atomizer 10 in this application uses microwave heating. The aerosol-generating article needs to be inserted into the atomizer 10 to be heated or vibrated to generate an aerosol, which is then inhaled by the user. The battery assembly 30 can be used to power the atomizer 10, enabling it to operate normally and generate an aerosol.

[0037] Please refer to Figure 2 and Figure 3 The atomizer 10 of this application includes a heating element 11 and an radio frequency (RF) element 13. The heating element 11 includes a loading member 111, which has a loading cavity 1111 configured to load an aerosol-generating article. The RF element 13 includes a substrate 131, an RF power chip 132, a circulator 133, and an RF resistor 134. Both the RF power chip 132 and the circulator 133 are disposed on the substrate 131. The RF power chip 132 is configured to generate a high-frequency RF signal. The circulator 133 includes a first terminal A, a second terminal B, and a third terminal C. The first terminal A of the circulator 133 is electrically connected to the RF power chip 132, the second terminal B of the circulator 133 is electrically connected to the loading member 111, and the RF resistor 134 is disposed outside the substrate 131 and electrically connected to the third terminal C of the circulator 133. The circulator 133 is configured to: transmit the radio frequency signal generated by the radio frequency power chip 132 to the loading member 111 through the first terminal A and the second terminal B when the atomizer 10 is in the first state, thereby heating the aerosol to generate an article; and transmit the radio frequency signal generated by the radio frequency power chip 132 to the radio frequency resistor 134 through the third terminal C when the atomizer 10 is in the second state.

[0038] For details, please refer to Figure 2The atomizer 10 of this application is a structure used to heat an aerosol generating article to produce an aerosol for a user to inhale. The atomizer 10 includes a heating element 11 and an radio frequency component 13. The heating element 11 is a component used to heat the aerosol generating article. The heating element 11 includes a loading member 111, which is provided with a loading cavity 1111, which is a cavity structure for loading the aerosol generating article. The loading member 111 loads the aerosol generating article through the loading cavity 1111. The loaded aerosol generating article can be transferred to the heating element 11 for microwave heating to generate an aerosol. The loading cavity 1111 is in communication with the outside of the aerosol generating device 100 so that the aerosol generating article can be loaded therein. The aerosol generating article can also be removed from the loading cavity 1111 after inhalation, and the user can further replace it with a new aerosol generating article in the loading cavity 1111. Furthermore, the aerosol generating device 100 may also include a dust cover (not shown), which can be closed or opened to switch between communication and non-communication between the loading cavity 1111 and the outside world.

[0039] The radio frequency (RF) component 13 is a component that generates high-frequency RF signals and transmits them to the loading component 111. The RF component 13 includes a substrate 131, an RF power chip 132, a circulator 133, and an RF resistor 134. The substrate 131 is a plate-shaped device in the RF component 13 used to mount other functional devices. The substrate 131 can be made of, but is not limited to, ceramic, PTFE composite material, and metal. When the substrate 131 is made of ceramic, it can be used in high-power and high-temperature applications. When the substrate 131 is made of PTFE composite material, it offers advantages such as low loss and lightweight design. When the substrate 131 is made of metal, it has good heat dissipation performance, making it suitable for applications requiring high-frequency optimized design.

[0040] A radio frequency (RF) power chip 132 and a circulator 133 are disposed on the substrate 131. The RF power chip 132 is a device used to generate RF signals. The RF power chip 132 can be, but is not limited to, a silicon-based RF power device, a gallium nitride (GaN) RF power device, or a silicon carbide (SiC) RF power device. When the RF power chip 132 is a silicon-based RF power device, it has the advantages of low cost and easy mass production. When the RF power chip 132 is a GaN RF power device, it has the advantages of high power density and high operating frequency. When the RF power chip 132 is a SiC RF power device, it has the advantages of high temperature resistance and suitability for pulse heating modes. The high-frequency RF signal generated by the RF power chip 132 is transmitted to the heating component 11 and can act on the aerosol generation product in the loading cavity 1111 to heat and atomize the aerosol generation product to generate aerosol.

[0041] Circulator 133 is a device that protects RF power chip 132. Signals inside circulator 133 are configured to flow in only one direction. Please refer to further details. Figure 5 The circulator 133 includes a first end A, a second end B, and a third end C, sequentially distributed in a preset signal flow direction. That is, within the circulator 133, the signal can only flow from the first end A to the second end B, from the second end B to the third end C, and first from the first end A to the second end B and then to the third end C. The first end A of the circulator 133 is electrically connected to the RF power chip 132, and the second end B of the circulator 133 is electrically connected to the loading component 111. The third end C of the circulator 133 is electrically connected to the RF resistor 134. The RF resistor 134 generates heat during operation. The RF resistor 134 is used to protect the RF power chip 132 when an atomizer 10 malfunctions, causing a short circuit or open circuit in the energy transmission path.

[0042] The radio frequency resistor 134 is disposed outside the substrate 131, meaning that the radio frequency resistor 134 does not directly contact the substrate 131; there is at least a certain distance, or even a complete separation, between them. Depending on the operating state of the atomizer 10, the circulator 133 is configured to have two states. The first state is when the atomizer 10 achieves perfect impedance matching. In the first state, the high-frequency radio frequency signal generated by the radio frequency power chip 132 is transmitted to the loading component 111 through the first terminal A and the second terminal B. The loading component 111 heats the aerosol via the radio frequency signal to form the article. The atomizer 10 is in a state of imperfect impedance matching, specifically when the impedance of the second terminal B is not perfectly matched with that of the heating element 11. In this second state, at least a portion of the radio frequency (RF) signal generated by the RF power chip 132 is transmitted to the third terminal C. Energy is then transferred to the RF resistor 134 via the connection between the third terminal C and the RF resistor 134, and finally to ground (the RF resistor 134 is grounded through the housing of the atomizer 10). Thus, the high-frequency RF signal is transmitted, and current flows through the RF resistor 134, generating heat. Since the RF resistor 134 is located outside the substrate 131, the heat generated by the RF resistor 134 does not act on the RF power chip 132 through the substrate 131. This design protects the RF power chip 132, ensuring its efficiency and guaranteeing the normal operation of both the atomizer 10 and the aerosol generator 100.

[0043] Please refer to this as well. Figures 3 to 5 In some embodiments, the radio frequency resistor 134 is disposed on the loading member 111.

[0044] Specifically, the RF resistor 134 being mounted on the loading component 111 means that the RF resistor 134 is configured to be directly mounted on and connected to the loading component 111. The connection between the RF resistor 134 and the loading component 111 can be detachable or non-detachable. Detachable connections include, but are not limited to, one or more combinations of screw connections and snap-fit ​​connections. Non-detachable connections include, but are not limited to, one or more combinations of gluing, welding, and sintering. When the atomizer 10 is in the second state, at least a portion of the RF signal generated by the RF power chip 132 is transmitted to the third terminal C, and energy is then transferred to the RF resistor 134 through the connection between the third terminal C and the RF resistor 134. Since the RF resistor 134 is directly mounted on the loading component 111, the heat generated by the RF resistor 134 is transferred to the loading component 111, and the heat generated by the RF resistor 134 compensates for the heat required by the atomizer 10 to heat the aerosol-generating product. At this time, the RF resistor 134 not only protects the RF power chip 132, but also allows the heat generated by the RF resistor 134 to be reused in the atomizer 10, thus saving energy and reducing power consumption.

[0045] Please refer to this as well. Figures 2 to 4 In some embodiments, the RF assembly 13 further includes an RF housing 135, which is connected to the loading member 111. The substrate 131, the RF power chip 132, and the circulator 133 are all disposed in the RF housing 135. The loading member 111 includes a first side 11101 connected to the RF housing 135. An RF resistor 134 is disposed on the first side 11101 of the loading member and is located outside the loading cavity 1111.

[0046] The RF housing 135 is a component in the RF assembly 13 that provides mounting positions for functional devices such as the substrate 131, the RF power chip 132, and the circulator 133. Simultaneously, the RF housing 135 is a component that connects the RF assembly 13 to the mounting component 111. The connection between the RF housing 135 and the mounting component 111 can be detachable or non-detachable. Detachable connections include, but are not limited to, one or more combinations of screw connections and snap-fit ​​connections. Non-detachable connections include, but are not limited to, one or more combinations of gluing, welding, and sintering methods. Please refer to further details. Figure 4 This application takes the connection between the RF housing 135 and the loading member 111 via a snap-fit ​​connection as an example. The RF housing 135 is provided with a connecting member 1351, and the loading member 111 is provided with a connecting member 1351. The connecting member 1351 and the mating member 1113 cooperate and connect with each other to connect the RF housing 135 and the loading member 111.

[0047] The side of the loading member 111 that connects to the RF housing 135 is the first side 11101 of the loading member, and the mating member 1113 is disposed on the first side 11101 of the loading member. The side of the RF housing 135 that connects to the loading member 111 is the first side 13501 of the RF housing, and the connecting member 1351 is disposed on the first side 13501 of the RF housing. Some embodiments of this application (please refer to them as well) Figure 3 and Figure 4 In this embodiment, the connector 1351 includes two first through holes and one second through hole, and the mating member 1113 includes two first protrusions and one second protrusion. Each first through hole is configured to mate with a corresponding first protrusion, and the second through hole is configured to mate with a second protrusion. In other embodiments (not shown), the connector 1351 includes two first protrusions and one second protrusion, and the mating member 1113 includes two first through holes and one second through hole. Each first protrusion is configured to mate with a corresponding first through hole, and the second protrusion is configured to mate with a second through hole. An RF resistor 134 is disposed on the first side 11101 of the loading member. In this case, the connection path between the RF resistor 134 and the circulator 133 is the shortest. This arrangement improves the transmission efficiency of the RF signal. Simultaneously, since the RF resistor 134 is located outside the loading cavity 1111, the heat generated by the RF resistor 134 can radiate into the loading cavity 1111, allowing this heat to be utilized in the aerosol generating device 100.

[0048] Please refer to this as well. Figure 3 and Figure 4 In some embodiments, the first side 11101 of the loading member is provided with a groove 1115, and the radio frequency resistor 134 is at least partially housed in the groove 1115.

[0049] Specifically, the groove 1115 is a spatial structure for accommodating the RF resistor 134. The groove 1115 can be, but is not limited to, a stepped groove formed by one or more of the following: a rectangular groove, a U-shaped groove, a V-shaped groove, and an irregular groove. The size and shape of the groove 1115 correspond to the size and shape of the RF resistor 134. The groove 1115 is disposed on the first side 11101 of the loading member, and its position corresponds to the first side 13501 of the RF housing. The RF resistor 134 is at least partially accommodated within the groove 1115; that is, the RF resistor 134 is completely accommodated within the groove 1115 and does not protrude from the first side 11101 of the loading member; or, a portion of the RF resistor 134 is accommodated within the groove 1115, and another portion of the RF resistor 134 protrudes from the first side 11101 of the loading member. The fact that the RF resistor 134 is at least partially accommodated within the groove 1115 saves space in the first direction L (defined as the length direction of the atomizer 10). Furthermore, the groove 1115 guides the installation position of the RF resistor 134, and the groove 1115 provides a mating surface for the installation of the RF resistor 134 through its inner wall. Therefore, the setting of the groove 1115 can also simplify the installation process of the RF resistor 134, thereby simplifying the assembly process of the atomizer 10.

[0050] Please refer to this as well. Figure 4 and Figure 5 In some embodiments, the RF assembly 13 further includes a first electrical connector 137. The RF housing 135 includes a first side 13501 connected to the loading member 111 and a second side 13502 connected to the first side 13501. The first side 13501 of the RF housing has an opening 1353, and the second side 13502 of the RF housing has a through hole 1354. The first electrical connector 137 passes through the through hole 1354 and the opening 1353 in sequence, and is electrically connected to the third terminal C of the circulator 133 and the RF resistor 134.

[0051] Specifically, the first electrical connector 137 is a device used to connect the third terminal C of the circulator 133 to the RF resistor 134. The first electrical connector 137 can be, but is not limited to, an RF coaxial cable, a glass bead connector, or an RF connector. When the first electrical connector 137 is an RF coaxial cable, it has advantages such as good shielding, strong electromagnetic interference resistance, and flexible layout. When the first electrical connector 137 is a glass bead connector, it has advantages such as high temperature resistance and compact structure. When the first electrical connector 137 is an RF connector, it has advantages such as pluggability and ease of maintenance. This application takes an RF coaxial cable (not shown) as an example. The first side 13501 of the RF housing has an opening 1353, and the second side 13502 of the RF housing has a through hole 1354. Both the opening 1353 and the through hole 1354 are used to provide a path for the installation of the first electrical connector 137. The first electrical connector 137 passes through the through hole 1354 and the opening 1353 in sequence, and is electrically connected to the third terminal C of the circulator 133 and the radio frequency resistor 134.

[0052] Please refer to this as well. Figure 4 and Figure 5 In some embodiments, the RF assembly 13 further includes a second electrical connector 139. The RF housing 135 includes a first side connected to the loading member 111 and a second side 13502 connected to the first side 13501 of the RF housing. The first side 13501 of the RF housing has an opening 1353, and the second side 13502 of the RF housing has a through hole 1354. The second electrical connector 139 passes through the through hole 1354 and the opening 1353 in sequence, and is electrically connected to the second end B of the circulator 133 and the loading member 111.

[0053] Specifically, the second electrical connector 139 is a device used to connect the second end B of the circulator 133 to the loading member 111. The second electrical connector 139 can be, but is not limited to, an RF coaxial cable, a glass bead connector, and an RF connector. When the second electrical connector 139 is an RF coaxial cable, it has advantages such as good shielding, strong electromagnetic interference resistance, and flexible layout. When the second electrical connector 139 is a glass bead connector, it has advantages such as high temperature resistance and compact structure. When the second electrical connector 139 is an RF connector, it has advantages such as pluggability and ease of maintenance. This application takes an RF coaxial cable (not shown) as an example where the second electrical connector 139 is the RF coaxial cable. The first side 13501 of the RF housing has an opening 1353, and the second side 13502 of the RF housing has a through hole 1354. Both the opening 1353 and the through hole 1354 are used to provide a path for the installation of the second electrical connector 139. The second electrical connector 139 passes through the through hole 1354 and the opening 1353 in sequence, and is electrically connected to the second end B of the circulator 133 and the loading member 111.

[0054] Please refer to this as well. Figure 2 and Figure 4 In some embodiments, the RF housing 135 includes a first housing 1356 and a second housing 1357. The second housing 1357 is connected to the first housing 1356 and forms a receiving cavity 1358. The substrate 131, the RF power chip 132, and the circulator 133 are all housed in the receiving cavity 1358.

[0055] Specifically, the first shell 1356 is the shell portion containing the second side 13502 of the RF shell, and the second shell 1357 is the shell portion of the RF shell 135 excluding the first shell 1356. The second shell 1357 is connected to the first shell 1356, and the connection between the second shell 1357 and the first shell 1356 can be detachable or non-detachable. Detachable connections include, but are not limited to, one or more combinations of screw connections and snap-fit ​​connections. Non-detachable connections include, but are not limited to, one or more combinations of gluing, welding, and sintering methods. Please refer to further details. Figure 4 The first housing 1356 and the second housing 1357 form a receiving cavity 1358. The receiving cavity 1358 is configured to house the substrate 131, the RF power chip 132, and the circulator 133. The receiving cavity 1358 may also be configured to house other functional devices (not shown). The size and shape of the receiving cavity 1358 must be compatible with the individual sizes and shapes of the substrate 131, the RF power chip 132, the circulator 133, and other functional devices (not shown), as well as the overall size and shape of the combination of the above devices.

[0056] Please refer to Figure 4 In some implementations, the RF power chip 132 is further away from the RF resistor 134 than the circulator 133.

[0057] Specifically, the circulator 133 and the RF power chip 132 are both distributed on the substrate 131 and located within the accommodating cavity 1358, and both the circulator 133 and the RF power chip 132 are at a certain distance from the RF resistor 134. Compared to the circulator 133, the RF power chip 132 is further away from the RF resistor 134, that is, in the first direction, the RF resistor 134, the circulator 133, and the RF power chip 132 are distributed sequentially. The RF resistor 134 is further away from the RF power chip 132 than the circulator 133, which not only ensures the signal transmission efficiency between the RF resistor 134 and the circulator 133, but also effectively reduces the energy directly transmitted from the RF resistor 134 to the RF power chip 132 through means other than electrical connection, further improving the safety of the atomizer 10.

[0058] Please refer to Figure 4 and Figure 5In some embodiments, the radio frequency component 13 further includes a matching circuit 136. The radio frequency power chip 132 is electrically connected to a first terminal A of the circulator 133 via the matching circuit 136. The matching circuit 136 is configured to match the output impedance of the radio frequency power chip 132 with the input impedance of the circulator 133.

[0059] For details, please refer to Figure 4 Matching circuit 136 is a circuit designed to optimize energy transmission efficiency and protect the RF power chip 132 and circulator 133. Matching circuit 136 is configured to connect the first terminal A of the RF power chip 132 and the circulator 133. Matching circuit 136 adjusts the impedance to match the output impedance of the RF power chip 132 with the input impedance of the circulator 133. Matching circuit 136 enables the high-frequency RF signal generated by the RF power chip 132 to be transmitted to the circulator 133 at maximum power, and further to the loading component 111. Therefore, matching circuit 136 can reduce energy loss during high-frequency RF signal transmission and further avoid the risk of overheating and damage to the RF power chip 132 due to abnormal RF signal transmission under imperfect impedance matching. Thus, matching circuit 136 effectively protects the RF power chip 132 and the circulator 133.

[0060] In summary, in the atomizer 10 and aerosol generating apparatus 100 of this application, the radio frequency power chip 132 and the circulator 133 are disposed on the substrate 131, and the radio frequency power chip 132 generates a high-frequency radio frequency signal. The radio frequency resistor 134 is disposed outside the substrate 131 and is not disposed together with the radio frequency power chip 132. The circulator 133 includes a first terminal A, a second terminal B, and a third terminal C. When the atomizer 10 is in different states, the signal in the circulator 133 is configured to different transmission paths. When the atomizer 10 is working normally, the radio frequency signal generated by the radio frequency power chip 132 is transmitted to the loading member 111 through the first terminal A and the second terminal B to heat the aerosol generating product. When the impedance of the atomizer 10 is not perfectly matched, that is, when the impedance of the second terminal B is not perfectly matched with that of the heating component 11, at least a portion of the radio frequency signal generated by the radio frequency power chip 132 is transmitted to the radio frequency resistor 134 through the third terminal C. Since the RF resistor 134 is located outside the substrate 131, the heat on the RF resistor 134 can be prevented from acting on the RF power chip 132 through the substrate 131. The working efficiency of the RF power chip 132 will not be affected, thus ensuring the normal operation of the atomizer 10 and the aerosol generating device 100.
