[0038] The atomizing device host device provided by the present application is provided with an integrated air duct assembly in the assembly groove of the air duct structure to be assembled and connected with the air duct structure, wherein the air duct structure has an air inlet hole, a first exhaust hole and a second exhaust hole connected to the assembly groove, and a first air duct and a second air duct are provided in the air duct assembly, and the first air duct can be connected to the first exhaust hole for sensing airflow; the two ends of the second air duct are respectively connected to the air inlet hole and the second exhaust hole; the first air duct and the second air duct are combined to form two independent air flow channels. When applied to the atomizing device, the air flow channel formed by the first air duct serves as the sensing air channel of the atomizing device, and the air flow channel formed by the second air duct serves as the main air channel of the atomizing device. Through the above scheme of the present application, compared with the traditional atomizing device, the number and type of parts can be greatly reduced, and there is no need to set up other connecting structures. The overall structure can be effectively simplified, the equipment cost can be reduced, and the space occupied is relatively small, which can make full use of the limited installation space and is suitable for application in miniaturized atomizing devices.

[0039] Some embodiments of the atomizing device host device, atomizing device, and airway assembly provided by the present application are described below with reference to the accompanying drawings.

[0040] In the embodiment of the first aspect of the present application, a host device 100 of an atomizing device is provided. Figure 1 、 Figure 2 and Figure 3 As shown, it includes an airway structural member 11 and an airway assembly member 12. The airway structural member 11 has an assembly end 110, which is located at one end of the airway structural member 11 in the first direction. Figure 1 and Figure 2 In the example, the first direction is the height direction of the atomizing device host device 100; when used in the atomizing device, the assembly end 110 of the airway structure 11 is used to assemble and connect with the atomizer. The airway structure 11 has an assembly groove 113 and an air inlet 115, and the assembly end 110 of the airway structure 11 has a first exhaust hole 111 and a second exhaust hole 112. The air inlet 115, the first exhaust hole 111 and the second exhaust hole 112 are all connected to the assembly groove 113. Figure 3 、 Figure 4 and Figure 5As shown, the air duct assembly 12 is at least partially arranged in the assembly groove 113 of the air duct structural member 11, so that the air duct assembly 12 is connected and assembled with the air duct structural member 11; the air duct assembly 12 has a first air duct 121 and a second air duct 122 which are independent of each other, and the first air duct 121 is used to install the airflow sensor 14, and the first air duct 121 is connected to the first exhaust hole 111, so that the airflow can be sensed by the airflow sensor 14 connected to the first air duct 121 when in use; one end of the second air duct 122 is connected to the air inlet hole 115, and the other end of the second air duct 122 is connected to the second exhaust hole 112. Through the cooperation of the first air channel 121 and the second air channel 122 with the assembly groove 113, two independent airflow channels are connected to form, which serve as the sensing air channel and the main air channel of the atomization device respectively, wherein the airflow channel formed by the first air channel 121 is the sensing air channel, and the airflow channel formed by the second air channel 122 is the main air channel; the airflow sensor 14 can be installed in the sensing air channel, and the suction action is sensed by the airflow sensor 14 in the sensing air channel; the main air channel is connected to the atomization core of the atomizer to transmit the aerosol generated by the atomization core through the airflow movement in the main air channel.

[0041] It should be noted that the air inlet 115 can be positioned appropriately based on the overall design and assembly requirements, for example, on the side of the air duct structure 11. The assembly groove 113 can be positioned appropriately based on the relative positions of the air inlet 115, the first exhaust hole 111, and the second exhaust hole 112 to facilitate assembly of the air duct assembly 12 and connection of the first air duct 121 and the second air duct 122.

[0042] It is understandable that other atomization devices usually require the provision of multiple different plastic parts and multiple silicone parts, which are assembled together to form the sensing airway and the main airway. Due to the large number and variety of parts, and their different shapes and structures, the overall structure is relatively complex, the overall cost is high, and a large space is required after assembly, which is not conducive to the miniaturization design of the atomization equipment.

[0043] The atomizer device host device 100 in this embodiment, by arranging an integrated airway assembly part 12 in the assembly groove 113 of the airway structural part 11, and arranging a first airway 121 and a second airway 122 independent of each other in the airway assembly part 12, can serve as the sensing airway and the main airway respectively after being assembled with the atomizer, and the airway assembly part 12 can directly form an assembly connection with the airway structural part 11 without the need for other auxiliary structures, thereby reducing the number of parts and the space occupied, which is conducive to simplifying the equipment structure, reducing costs, and is conducive to application in miniaturized atomizer equipment.

[0044] Among them, in actual application, in order to improve air tightness, a sealing protrusion structure (such as a raised sealing ring structure or a rib structure) can be provided at the position corresponding to the surface of the air duct assembly 12 and the first air duct 121 and the second air duct 122, so that when the air duct assembly 12 is assembled in the assembly groove 113 of the air duct structural component 11, the sealing protrusion structure and the inner wall surface of the assembly groove 113 are used to form an interference fit, thereby sealing the first air duct 121 and the second air duct 122.

[0045] In a further embodiment of the present application, Figures 1 to 3 As shown, the assembly groove 113 is arranged along the second direction relative to the airway structural member 11, and the second direction is perpendicular to the first direction, for example Figure 1 In the example in FIG. 1 , the second direction may be the thickness direction of the atomizing device main unit 100. The assembly groove 113 has an open end and a groove bottom end. In the second direction, the open end passes through one side of the airway structural member 11, and the airway assembly member 12 can be installed into the assembly groove 113 from the open end. The groove bottom end of the assembly groove 113 is provided with a first assembly hole 114. Accordingly, as Figure 4 and Figure 5 In the example, on the air duct assembly 12 , one end of the first air duct 121 extends toward the assembly end 110 of the air duct structure 11 and communicates with the first exhaust hole 111 , and the other end of the first air duct 121 extends toward the bottom end of the assembly groove 113 . Among them, the air duct assembly 12 has a first protrusion 123 on the side facing the bottom end of the groove, the first protrusion 123 is inserted into the first assembly hole 114, and the first protrusion 123 has a first groove structure 1231 on the end face in the second direction, the first air duct 121 passes through the first protrusion 123 and extends into the first groove structure 1231, that is, the internal space of the first groove structure 1231 is also part of the first air duct 121; the first groove structure 1231 is used to accommodate the air flow sensor 14, so that when the air flow sensor 14 is installed in the first groove structure 1231, when gas flow is generated in the first air duct 121, the air flow sensor 14 can sense the air flow movement under the action of negative pressure and generate a sensing signal, thereby sensing the suction action.

[0046] The shape of the first groove structure 1231 can be designed according to the airflow sensor 14 to facilitate assembly and fixation of the airflow sensor 14. In addition, the first protrusion 123 is a part of the airway assembly 12 and is integrally formed with the main body of the airway assembly 12.

[0047] Furthermore, in one implementation, Figure 4 and Figure 5In the example shown in FIG1 , at least a portion of the first slot structure 1231 extends out of the first assembly hole 114 in the second direction to facilitate assembly of the airflow sensor 14. A first sealing protrusion 1232 is provided on the end surface of the first slot structure 1231 in the second direction. The first sealing protrusion 1232 extends around the opening of the first slot structure 1231. The first sealing protrusion 1232 is a specific implementation of the sealing protrusion structure described above. After the airflow sensor 14 is installed in the first slot structure 1231, a matching mating member 142 can be provided. The mating member 142 is positioned corresponding to the end surface of the first slot structure 1231, and the first sealing protrusion 1232 abuts against the surface of the mating member 142 to provide sealed protection for the airflow sensor 14. The mating member 142 can be a circuit board that is compatible with the airflow sensor 14. Alternatively, the mating member 142 can be a structural member used to facilitate assembly of the airflow sensor 14. It will be appreciated that, typically, the airflow sensor 14 needs to be connected to a circuit board or other electronically controlled components. If the first slot structure 1231 is completely located within the first assembly hole 114, the connection and assembly of the airflow sensor 14 will be more difficult. By extending at least a portion of the first slot structure 1231 outside the first assembly hole 114, the assembly and connection of the airflow sensor 14 is facilitated, and the first sealing protrusion 1232 and the mating member 142 can be used to provide sealed protection for the airflow sensor 14.

[0048] Furthermore, in another specific implementation, as Figure 4 、 Figure 5 and Figure 6 In the example, the third direction is perpendicular to the first direction and the second direction, and can be specifically the width direction of the atomizing device host device 100. Accordingly, the first exhaust hole 111 and the second exhaust hole 112 are also spaced apart in the third direction. In the third direction, the airway assembly 12 has a second protrusion 124 on the side close to the second airway 122; inside the airway assembly 12, as shown in FIG. Figure 7 and Figure 8 In the example, the second air duct 122 extends from one end away from the second exhaust hole 112 to the second protrusion 124 and penetrates the wall surface of the second protrusion 124 toward the bottom end of the groove in the second direction. Correspondingly, on the air duct structure 11, the air inlet 115 is located on the side near the second protrusion 124. Within the air duct structure 11, the air inlet 115 extends to a position at the bottom end of the assembly groove 113 opposite the second protrusion 124. The air inlet 115 is connected to the opening of the second air duct 122 on the second protrusion 124, so that the airflow entering the air inlet 115 can flow through the second air duct 122 of the air duct assembly 12 to the second exhaust hole 112. The first air duct 121 and the second air duct 122 are spaced apart in the third direction, which helps improve space utilization and optimize the air duct layout.

[0049] It is understandable that, generally speaking, the thickness of common atomization equipment is smaller, while the width is larger than the thickness, such as Figure 1 As shown in . In this embodiment, by arranging the connection surface between the second air channel 122 and the air inlet 115 in the second direction, that is, in the direction opposite to the bottom end of the assembly groove 113, more space is provided, and the opening can be designed to be larger. In addition, the assembly groove 113 has a structure that is compatible with the second protrusion 124. After the air channel assembly 12 is assembled in the assembly groove 113, the second protrusion 124 can also play a certain limiting role, preventing the air channel assembly 12 from shaking or rotating in the assembly groove 113, so as not to affect the connection between the first air channel 121 and the second air channel 122.

[0050] Furthermore, if Figure 8 In the example shown in FIG, within the airway assembly 12, the inner diameter of the second airway 122 is larger than the inner diameter of the first airway 121. When used in an atomizer device, the second airway 122 forms the main airway, which can increase the gas flow rate of the main airway to meet atomization needs. Since the first airway 121 is part of the sensing airway and is primarily used to sense gas flow via the airflow sensor 14, providing the first airway 121 with a smaller inner diameter can increase the airflow velocity within the first airway 121 when the user inhales, allowing the airflow sensor 14 to sense gas flow more quickly, thereby improving the sensitivity and efficiency of atomization control.

[0051] In a further embodiment of the present application, Figure 4 、 Figure 7 and Figure 8 As shown, the air duct assembly 12 also has a third protrusion 125, which faces the assembly end 110 of the air duct structure 11 and extends along the first direction; the first air duct 121 and the second air duct 122 both extend to the end surface of the third protrusion 125 in the first direction, and each forms an independent port. The third protrusion 125 also has a sealing protrusion structure on the end surface in the first direction, and the sealing protrusion structure is interference-fitted with the side wall of the assembly groove 113 to seal the first air duct 121 and the second air duct 122. Specifically, as shown in FIG. Figure 4 In the example, the sealing protrusion structure includes a second sealing protrusion 1251 and a third sealing protrusion 1252. The second sealing protrusion 1251 is located at the peripheral position of the port of the first air channel 121 and is arranged around the circumference of the first air channel 121; the third sealing protrusion 1252 is located at the peripheral position of the port of the second air channel 122 and is arranged around the circumference of the second air channel 122. Figure 8In the example shown in FIG1 , both the second sealing protrusion 1251 and the third sealing protrusion 1252 abut against the inner sidewall of the assembly groove 113, so that the second sealing protrusion 1251 seals the connection between the first air channel 121 and the first exhaust hole 111, and the third sealing protrusion 1252 seals the connection between the second air channel 122 and the second exhaust hole 112. The second sealing protrusion 1251 and the third sealing protrusion 1252 are both specific implementations of the sealing protrusion described above; of course, the sealing protrusion structure here can also be an integrated structure, simultaneously sealing the first air channel 121 and the second air channel 122.

[0052] In a further embodiment of the present application, Figure 7 and Figure 8 In the example, in the third direction, at least one side of the third protrusion 125 has an assembly protrusion structure 1253, and the side wall of the assembly groove 113 has an assembly card groove structure 1131 adapted to the assembly protrusion structure 1253, so that after the airway assembly 12 is assembled, the assembly protrusion structure 1253 can be snap-fitted with the assembly card groove structure 1131 of the assembly groove 113 to further improve the connection stability between the airway assembly 12 and the assembly groove 113.

[0053] Furthermore, if Figures 5 to 8 As shown, the hardness of the airway assembly 12 is less than that of the airway structural member 11, so that during the assembly process, the airway assembly 12 can produce a certain amount of deformation and be installed in the assembly groove 113 of the airway structural member 11, so that the airway assembly 12 and the airway structural member 11 are connected. For example, the airway assembly 12 can be made of a flexible material such as silicone or rubber, so that when installed in the assembly groove 113, it can form an interference fit to achieve the connection and assembly between the two without the need for additional corresponding connecting structures. In particular, since materials such as silicone and rubber have a certain degree of elasticity, the airway assembly 12 can be tightly fitted with the inner wall surface of the assembly groove after installation, which is conducive to further improving the sealing performance. In particular, the first protrusion 123, the second protrusion 124, the third protrusion 125, the first sealing protrusion 1232, the second sealing protrusion 1251, the third sealing protrusion 1252, and the assembly protrusion structure 1253 are all integrally formed with the airway assembly 12.

[0054] In a further embodiment of the present application, Figure 9 and Figure 10As shown, the main unit 100 of the atomizing device also includes a shell 13, an airflow sensor 14 and a power supply assembly 15. The airway structural part 11, the airway assembly part 12, the airflow sensor 14 and the power supply assembly 15 are all arranged in the shell 13; in the first direction, an assembly port 131 is provided at one end of the shell 13, and the assembly end 110 of the airway structural part 11 is located at the end facing the assembly port 131. When used in the atomizing device, it can be connected and assembled with the atomizer through the assembly port 131. The airflow sensor 14 is arranged in the first air duct 121, and the power supply assembly 15 is electrically connected to the airflow sensor 14; when used in the atomizing device, the power supply assembly 15 can also be electrically connected to the atomizer core of the atomizer to supply power to the atomizer core; when the airflow sensor 14 generates a sensing signal, the power supply assembly 15 can obtain the sensing signal and control the power supply state of the atomizer core to realize the control operation of the atomization heating. Specifically, as Figure 5 and Figure 10 In the example, when the air duct assembly 12 has a first protrusion 123 on the side facing the bottom end of the groove, and the first protrusion 123 has a first groove structure 1231 on the end face in the second direction, the first air duct 121 passes through the first protrusion 123 and extends into the first groove structure 1231, and the airflow sensor 14 is installed in the first groove structure 1231.

[0055] Furthermore, if Figure 10 In the example, the power supply assembly 15 may include a battery unit 151 and an electronic control element 152 electrically connected thereto. The electronic control element 152 performs corresponding calculations based on the sensing signal from the airflow sensor 14 and generates corresponding control instructions to control the power supply status of the battery unit 151 to the atomizer. For example, when the airflow sensor 14 triggers a sensing signal, indicating that the user is taking a puff, the electronic control element 152 receives the sensing signal and controls the battery unit 151 to supply power to the atomizer, thereby performing atomization and heating operations to generate aerosol. The electronic control element 152 includes, but is not limited to, a device having a control circuit.

[0056] The embodiment of the second aspect of the present application provides an atomization device 200, such as Figures 9 to 11 As shown, the atomizing device 200 includes the atomizing device host device 100 and the atomizer 21 in any embodiment of the first aspect. The atomizer 21 is detachably electrically connected to the atomizing device host device 100 (for example, Figure 9 The assembly end 110 shown in the figure is detachably connected) to assemble into the atomizing device 200. The atomizer 21 can generate aerosol by heating and atomizing the aerosol matrix. The atomizer 21 has an airway inside that connects the first exhaust hole 111 and the second exhaust hole 112, so that the generated aerosol moves to the suction end together with the airflow.

[0057] The atomizing device 200 in this embodiment adopts the atomizing device host device 100 having the above-mentioned airway structural parts 11 and airway assembly parts 12, which simplifies the internal structure, reduces equipment costs, reduces space occupation, facilitates assembly and installation, and is conducive to achieving miniaturized design.

[0058] In addition, the atomization device 200 in this embodiment also has all the beneficial effects of the atomization device host device 100 in any of the above embodiments, which will not be repeated here.

[0059] Furthermore, in actual applications, the atomizer 21 can be provided with corresponding structures such as an atomizing core, an airway, a nozzle, and a liquid storage tank according to usage requirements.

[0060] In the embodiment of the third aspect of the present application, an airway assembly 12 is provided, such as Figures 3 to 5 As shown, the air duct assembly 12 is used to be assembled with the air duct structure 11 in any of the above embodiments to form the main unit 100 of the atomizing device, and the air duct assembly 12 can directly form a sealed assembly with the assembly groove 113 of the air duct structure 11. In the first direction, one end of the air duct assembly 12 has a first end face 1261, and in the second direction, one side of the air duct assembly 12 has a first side face 1262, and the second direction is perpendicular to the first direction. The air duct assembly 12 has a first air duct 121 and a second air duct 122 that are independent of each other; as shown in FIG. Figure 4 and Figure 8 In the example, one end of the first air duct 121 extends to the first end surface 1261 of the air duct assembly 12, and the other end of the first air duct 121 extends to the first side surface 1262 of the air duct assembly 12. Similarly, one end of the second air duct 122 extends to the first end surface 1261 of the air duct assembly 12, and the other end of the second air duct 122 extends to the first side surface 1262 of the air duct assembly 12. When assembled with the air duct structure 11 in any of the above embodiments, the airflow sensor 14 can be installed in the first air duct 121, and the first air duct is connected to the first exhaust hole 111 of the air duct structure for sensing airflow. The two ends of the second air duct 122 are respectively connected to the air inlet hole 115 and the second exhaust hole 112 of the air duct structure 11.

[0061] The air duct assembly 12 in this embodiment, when assembled on the air duct structural member 11, can directly form an assembly connection with the assembly groove 113 without the need for additional auxiliary structures. Moreover, the air duct assembly 12 has two independent air ducts, which can serve as the sensing air duct and the main air duct of the atomization equipment respectively to meet the use requirements of the atomization control operation, which is conducive to simplifying the structure, reducing space occupancy, and reducing equipment costs.

[0062] It should be noted that, in actual applications, the air duct assembly 12 can be made of a flexible structure such as silicone or rubber, which can facilitate assembly and further reduce costs. The directions of the first air duct 121 and the second air duct 122 can be set accordingly according to the positions of the air inlet and exhaust holes of the air duct structural component 11 to meet assembly requirements. In order to improve the airtightness after assembly, corresponding sealing protrusion structures (such as raised sealing ring structures or rib structures) can be set on the surface of the air duct assembly 12 at positions corresponding to the first air duct 121 and the second air duct 122. The first air duct 121 and the second air duct 122 are sealed by the interference fit between the sealing protrusion structure and the corresponding assembly structure (such as the assembly groove of the air duct structural component).

[0063] In a further embodiment of the present application, Figure 4 、 Figure 5 In the example, the first side of the air duct assembly 12 has a first protrusion 123, which extends along the second direction. A first groove structure 1231 is formed on the end surface of the first protrusion 123. The end of the first air duct 121, away from the first end surface 1261, passes through the first protrusion 123 and extends into the first groove structure 1231. That is, a portion of the first air duct 121 extends along the first direction, while another portion extends along the second direction, forming an L-shaped structure that bends along the second direction. When assembled with the air duct structural member 11 in any of the above embodiments, the first groove structure 1231 is used to mount the airflow sensor 14. When gas flow occurs within the first air duct 121, the airflow sensor 14 can sense the airflow movement and generate a sensing signal.

[0064] Furthermore, if Figure 4 and Figure 5 In the example, the first slot structure 1231 has a first sealing protrusion 1232 on the end face in the second direction, and the first sealing protrusion 1232 is arranged around the circumference of the first slot structure 1231, so that after the airflow sensor 14 is assembled with the corresponding matching part 142, the first sealing protrusion 1232 can be used to abut against the surface of the matching part 142 to achieve sealing protection of the airflow sensor 14.

[0065] In a further embodiment of the present application, Figure 4 、 Figure 5 and Figure 6 In the example, in the third direction perpendicular to the first direction and the second direction, the first air channel 121 and the second air channel 122 are spaced apart in the third direction. In the third direction, the air channel assembly 12 has a second protrusion 124 on one side close to the second air channel 122; inside the air channel assembly 12, as shown in FIG. Figure 7 and Figure 8In the example, the second air duct 122 extends from one end of the first end surface 1261 to the second protrusion 124 and passes through the second protrusion 124 in the second direction, so that the second air duct 122 forms an L-shaped structure bent along the third direction. When the air duct assembly is assembled with the air duct structural member 11 in any of the above embodiments, as shown in FIG. Figure 3 In the example, the bending structure of the second air duct 122 can be adapted to the air inlet hole 115 on the side of the air duct structural component 11.

[0066] Through the above arrangement, the first air duct 121 and the second air duct 122 can form two different directions, so as to form two different air flow channels after being assembled and connected with the air duct structure 11, so as to respectively meet the functional requirements of inducing air flow and main air duct intake.

[0067] It should be noted that the cross-sectional shapes of the first air channel 121 and the second air channel 122 can be set according to specific air intake needs and design requirements, for example Figure 4 In the example shown in FIG, the first air channel 121 adopts a circular hole structure, and the second air channel 122 adopts a rectangular hole structure.

[0068] In a further embodiment of the present application, Figures 3 to 5 As shown, the air duct assembly 12 has a third protrusion 125 extending in the first direction. The end surface of the third protrusion 125 in the first direction is the first end surface 1261 of the air duct assembly 12. The first air duct 121 and the second air duct 122 both extend to the first end surface 1261 and form independent ports. The first end surface 1261 also has a sealing protrusion structure, such as Figure 4 and Figure 5 The second sealing protrusion 1251 and the third sealing protrusion 1252 shown in the figure are used to seal the first air channel 121 and the second air channel 122. Specifically, the second sealing protrusion 1251 is located at the peripheral position of the port of the first air channel 121 and is arranged around the circumference of the first air channel 121; the third sealing protrusion 1252 is located at the peripheral position of the port of the second air channel 122 and is arranged around the circumference of the second air channel 122. Figure 8 In the example, when the air duct assembly 12 is assembled in the air duct structural member 11 in any of the above embodiments, the second sealing protrusion 1251 and the third sealing protrusion 1252 are both in contact with the inner wall of the assembly groove 113, so that the second sealing protrusion 1251 forms a seal on the connection between the first air duct 121 and the first exhaust hole 111, and the third sealing protrusion 1252 forms a seal on the connection between the second air duct 122 and the second exhaust hole 112.

[0069] In a further embodiment of the present application, Figure 7 and Figure 8In the example, in the third direction, at least one side of the third protrusion 125 has an assembly protrusion structure 1253, so that after the airway assembly 12 is assembled, the assembly protrusion structure 1253 can be snap-fitted with the assembly groove 113. For example, a matching assembly slot structure 1131 is provided on the side wall of the assembly groove 113 to utilize the snap-fitting cooperation between the assembly protrusion structure 1253 and the assembly slot structure 1131 to further improve the connection stability between the airway assembly 12 and the assembly groove 113.

[0070] Furthermore, if Figure 8 In the example shown in FIG, the inner diameter of the second air channel 122 is greater than the inner diameter of the first air channel 121. The first protrusion 123, the second protrusion 124, the third protrusion 125, the first sealing protrusion 1232, the second sealing protrusion 1251, the third sealing protrusion 1252, and the assembly protrusion structure 1253 are all integrally formed with the air channel assembly 12.

A first mounting hole 114 is formed in the bottom end, extending in the second direction. An air inlet hole 115 is formed on a sidewall adjacent to the bottom end, with the other end of the air inlet hole 115 extending from the bottom end and facing the open end. The mounting end 110 of the airway structural member 11 has a first exhaust hole 111 and a second exhaust hole 112, both spaced apart in the third direction.

Figure 8 In the example, inside the air duct assembly 12, the inner diameter of the second air duct 122 is larger than the inner diameter of the first air duct 121. The first side surface 1262 of the air duct assembly 12 has a first protrusion 123, and the first protrusion 123 has a first groove structure 1231 on the end surface in the second direction. The end of the first air duct 121 away from the first end surface 1261 passes through the first protrusion 123 and extends into the first groove structure 1231, that is, the internal space of the first groove structure 1231 is also part of the first air duct 121; the first protrusion 123 is arranged in the first assembly hole 114, and the airflow sensor 14 is installed in the first groove structure 1231.

A first sealing protrusion 1232 is provided on the end surface of the first slot structure 1231 in the second direction, and the first sealing protrusion 1232 is arranged circumferentially around the first slot structure 1231. A mating component 142 is provided corresponding to the first slot structure 1231. The mating component 142 is specifically a circuit board structure and abuts against the first sealing protrusion 1232 to form a seal with the airflow sensor 14.

[0075] In the third direction, the airway assembly 12 has a second protrusion 124 on one side close to the second airway 122; inside the airway assembly 12, as shown in FIG. Figure 7 and Figure 8 In the example shown in FIG, the second air channel 122 extends from one end away from the second exhaust hole 112 to the second protrusion 124 and penetrates the wall surface of the second protrusion 124 toward the bottom end of the groove in the second direction. Accordingly, the air inlet hole 115 of the air channel structure 11 is located on the side near the second protrusion 124. Within the air channel structure 11, the air inlet hole 115 extends to a position at the bottom end of the assembly groove 113 opposite the second protrusion 124, and the air inlet hole 115 communicates with the opening of the second air channel 122 on the second protrusion 124.

The third protrusion 125 has assembly protrusion structures 1253 on both sides in the third direction, and the assembly groove 113 has an assembly slot structure 1131 that matches the assembly protrusion structures 1253.
