Description

Technical Field

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

[0002] In related technologies, an atomizer generally includes a housing with a liquid storage space, an air vent tube disposed within the housing, and an atomizing core disposed within the air vent tube. The air vent tube is connected to the liquid storage space containing the atomizing liquid, so that the atomizing core heats and atomizes the atomizing liquid to generate an aerosol.

[0003] However, in order to accommodate the atomizer core, the part of the air tube where the atomizer core is assembled usually has a large outer contour dimension, which is not conducive to achieving an ultra-thin atomizer. Utility Model Content

[0004] In view of this, the embodiments of this application aim to provide an atomizer and aerosol generating device that can meet the requirements of ultra-thin design.

[0005] To achieve the above objectives, one embodiment of this application provides an atomizer, comprising:

[0007] A vent pipe includes a first pipe section and a second pipe section located at one end of the first pipe section and having a liquid guide port. The outer contour dimension of the second pipe section is larger than that of the first pipe section, so that the first pipe section and the second pipe section enter the receiving cavity sequentially through the installation port, and at least a portion of the structure of the second pipe section is constrained within the installation space. The liquid guide port is in communication with the liquid storage space.

[0008] The atomizing core is disposed in the second tube section and is in fluid communication with the liquid storage space through the liquid guide port.

[0009] In some embodiments, the inner wall of the receiving cavity includes a first inner wall and a second inner wall located on opposite sides of the receiving cavity along a second direction, at least one of the first inner wall and the second inner wall being recessed to form the mounting space, wherein the second direction intersects the first direction.

[0010] In some embodiments, the installation space is open on at least one side of opposite sides along a third direction to form an opening communicating with the liquid storage space, and the liquid guide port is exposed at the opening, wherein the third direction intersects the second direction and the first direction, respectively; and / or,

[0011] The portion of the second pipe section located within the installation space forms a gap region on the periphery of the installation space between it and the inner wall of the receiving cavity. The housing also includes a rib protruding from the inner wall of the receiving cavity, the rib being located at the gap region.

[0012] In some embodiments, the second pipe segment includes an extension segment and a connecting segment connected to the first pipe segment, the connecting segment gradually tapering from one end away from the first pipe segment to one end closer to the first pipe segment, and at least a portion of the structure of the extension segment and at least a portion of the structure of the connecting segment are constrained within the installation space.

[0013] In some embodiments, the recessed portion of the inner wall includes a first wall surface and a second wall surface located on the side of the first wall surface facing away from the mounting opening along the first direction, wherein the shape of the first wall surface matches the shape of the extension segment and the shape of the second wall surface matches the shape of the connecting segment.

[0014] In some embodiments, a portion of the structure of the second pipe segment is located within the mounting port and abuts against the inner wall of the mounting port.

[0015] In some embodiments, the housing has an air outlet and a first liquid storage tank, the air outlet and the first liquid storage tank being located on opposite sides of the receiving cavity along the first direction, and both being in fluid communication with the vent pipe.

[0016] In some embodiments, the housing has a communicating channel and a first communicating port and a second communicating port respectively communicating with the communicating channel. The communicating channel is located on the side of the mounting port away from the receiving cavity along the first direction and is in fluid communication with the vent pipe through the first communicating port.

[0017] The atomizer also includes a sensor mounting component disposed within the housing and having an airflow detection port, the airflow detection port being in fluid communication with the communication channel through the second communication port.

[0018] In some embodiments, the second connection port is located on the side of the sensor mounting member close to the mounting port along the first direction, the sensor mounting member also has a second liquid reservoir facing the second connection port, and the airflow detection port is offset from the second connection port.

[0019] In some embodiments, the second liquid storage tank is located on one side of the airflow detection port along a second direction, the second direction intersecting the first direction, and the sensor mounting component further has a sensor mounting cavity located on the side of the second liquid storage tank and the airflow detection port away from the second communication port along the first direction;

[0022] This application provides an atomizer and an aerosol generating device. The atomizer in this application uses a recessed section of the inner wall of the receiving cavity to create an installation space communicating with the liquid storage space. Even with a narrower housing, the interior of the housing still has a relatively large installation space to accommodate the second segment of the vent tube. Simultaneously, the housing has an installation port located on one side of the receiving cavity along a first direction and communicating with the installation space. During assembly, the first and second segments sequentially enter the receiving cavity through the installation port. That is, the first segment with the smaller outer contour dimension enters the receiving cavity first, followed by the second segment with the larger outer contour dimension. At least a portion of the structure of the second segment is constrained within the installation space. Compared to related technologies where the vent tube enters from the first side of the receiving cavity, in this application embodiment, the vent tube actually enters from the second side of the receiving cavity. Therefore, even with a narrower housing size, at least a portion of the second segment can extend into and be constrained within the installation space. Thus, the atomizer of this application embodiment can meet the requirements for ultra-thin design. Attached Figure Description

[0032] In the description of the embodiments in this application, it should be noted that the terms "first direction" and "second direction" are based on the appended... Figure 1 The orientation or positional relationship shown, "third direction" is based on the attached Figure 2 The orientation or positional relationship shown is merely for the convenience of describing the embodiments of this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the embodiments of this application.

[0033] This application provides an atomizer 10, please refer to... Figures 1 to 7 The atomizer 10 includes a housing 11, an air tube 12, and an atomizing core 13.

[0034] The housing 11 has a receiving cavity 11a and a mounting port 11b. The mounting port 11b is located on one side of the receiving cavity 11a along a first direction. The receiving cavity 11a includes a liquid storage space 11a1 and a mounting space 11a2 communicating with the mounting port 11b, wherein a portion of the inner wall of the receiving cavity 11a is recessed to form the mounting space 11a2 communicating with the liquid storage space 11a1. That is, there is a partial recessed area on the inner wall of the receiving cavity 11a, which together with an adjacent portion of the receiving cavity 11a forms the mounting space 11a2.

[0035] The vent pipe 12 includes a first pipe section 121 and a second pipe section 122 located at one end of the first pipe section 121 and having a liquid guide port 122a. The outer contour dimension of the second pipe section 122 is larger than that of the first pipe section 121, so that the first pipe section 121 and the second pipe section 122 enter the receiving cavity sequentially through the installation port 11b, and at least a part of the structure of the second pipe section 122 is constrained within the installation space 11a2. The liquid guide port 122a is connected to the liquid storage space 11a1.

[0036] In other words, during the assembly process, the vent pipe 12 is inserted into the receiving cavity 11a from the mounting port 11b. The first pipe segment 121, with a smaller outer contour dimension, extends into the receiving cavity 11a first from the mounting port 11b, followed by the second pipe segment 122, with a larger outer contour dimension. The outer contour dimension refers to the maximum outer boundary dimension of the cross-section. For example, if the first pipe segment 121 and the second pipe segment 122 are circular pipes, the outer contour dimension refers to the outer diameter; if the first pipe segment 121 and the second pipe segment 122 are polygonal pipes, elliptical pipes, etc., the outer contour dimension refers to the distance between the two points with the greatest distance on the cross-section.

[0037] For ease of description, the receiving cavity 11a is defined to have a first side X1 and a second side X2 along a first direction, and the mounting port 11b is located on the second side X2.

[0038] The constraint of at least a portion of the structure of the second pipe segment 122 within the installation space 11a2 means that when part or all of the structure of the second pipe segment 122 is located within the installation space 11a2, a portion of the structure of the second pipe segment 122 is located within a recessed area of ​​the inner wall of the receiving cavity 11a, and this recessed area can limit the second pipe segment 122 so that the second pipe segment 122 cannot slide out from the installation space 11a2 toward the first side X1.

[0039] Please see Figure 1 , Figure 5 and Figure 6 The vent pipe 12 has an airflow channel 12a. The cross-sectional dimension of the airflow channel 12a located in the second pipe section 122 is larger than that of the airflow channel 12a located in the first pipe section 121, so as to accommodate the atomizing core 13.

[0040] Please see Figures 1 to 3 , Figure 5 The atomizing core 13 is disposed within the second pipe section 122 and is in fluid communication with the liquid storage space 11a1 through the liquid guide port 122a. That is to say, the second pipe section 122 of the vent pipe 12 is used to accommodate the atomizing core 13. The atomizing core 13 is located in the airflow channel 12a of the second pipe section 122. The atomizing core 13 heats and atomizes the atomizing liquid, generating an aerosol that is directly released into the airflow channel 12a.

[0041] The structure of the atomizing core 13 is not limited; for example, please refer to [link to relevant documentation]. Figure 2 and Figure 5 The atomizing core 13 includes a cylindrical atomizing body 131 and a liquid guiding component 133 sleeved on the outer periphery of the atomizing body 131. The liquid guiding component 133 is in fluid communication with the liquid guiding port 122a to guide the atomizing liquid into the atomizing body 131.

[0042] For example, please refer to Figures 1 to 6 When at least a portion of the structure of the second pipe segment 122 is constrained within the installation space 11a2, and a portion of the structure of the first pipe segment 121 is located within the liquid storage space 11a1 while another portion is located outside the liquid storage space 11a1, by making the outer contour dimension of the second pipe segment 122 larger than that of the first pipe segment 121, the size of the liquid storage space 11a1 occupied by the first pipe segment 121 can be reduced while ensuring that the second pipe segment 122 can accommodate the atomizing core 13, thereby increasing the liquid storage capacity of the liquid storage space 11a1.

[0043] In other embodiments, the first pipe segment 121 may be entirely located within the liquid storage space 11a1, or entirely located outside the liquid storage space 11a1.

[0044] For example, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 Part of the structure of the second pipe section 122 is located in the installation space 11a2, while another part of the structure is located in the installation port 11b and abuts against the inner wall of the installation port 11b. In other words, part of the structure of the second pipe section 122 is interference-fitted with the installation port 11b to prevent the second pipe section 122 from shaking in the housing 11, thereby causing the atomizing liquid to leak out.

[0045] In another embodiment, the entire structure of the second pipe segment 122 may be located within the installation space 11a2, and the second pipe segment 122 is interference-fitted to the inner wall of the installation space 11a2.

[0046] Please see Figures 1 to 3 , Figure 5The housing 11 has an air outlet 11c that communicates with the air passage of the vent pipe 12. The air outlet 11c is located on the side of the receiving cavity 11a opposite to the mounting port 11b along the first direction.

[0047] The air outlet 11c refers to the outlet through which the aerosol flows from the airway into the user's mouth. The aerosol generated by the heating and atomizing of the atomizing liquid by the atomizing core 13 can be directly inhaled by the user through the air outlet 11c.

[0048] The air outlet 11c is located on the first side X1 of the receiving cavity 11a, and the mounting port 11b is located on the second side X2 of the receiving cavity 11a. That is to say, the air pipe 12 is installed into the receiving cavity 11a from the side away from the air outlet 11c along the first direction.

[0049] This application also provides an aerosol generating device, which further includes a power supply component 20 and an atomizer 10 provided in any embodiment of this application, wherein the power supply component 20 is electrically connected to the atomizer 10.

[0050] The aerosol generating device is used to produce aerosols for users to inhale or for medical, cosmetic, and other applications. The power supply assembly 20 typically includes a battery for powering the atomizer 10 and a control assembly for controlling the heating of the atomizer 10. The power supply assembly 20 works in conjunction with the atomizer 10 to power the atomizer 10 and control its operating state.

[0051] For example, please refer to Figure 5 The aerosol generating device also includes a first electrical connector 40 and a second electrical connector 50, which are used to electrically connect the atomizing core 13 to the power supply assembly 20 so that the power supply assembly 20 can supply power to the atomizing core 13.

[0052] Please see Figures 1 to 4 The aerosol generating device also includes an airflow sensor 30, which is in fluid communication with the air passage of the atomizer 10 and is signal-connected to the control component of the power supply component 20.

[0053] The airflow sensor 30 is used to detect the negative pressure in the airflow path within the aerosol generating device.

[0054] Furthermore, the control component within the aerosol generating device can control the atomizing core 13 based on the detection results of the airflow sensor 30. For example, when a user inhales the aerosol generating device, a negative pressure is generated in the airflow path within the aerosol generating device. The airflow sensor 30 detects the negative pressure generated in the airflow path and transmits the detection result to the control component. The control component determines that there is a negative pressure in the airflow path based on the detection result of the airflow sensor 30, and can then control the atomizing core 13 to be electrically connected to the power supply component 20, thereby starting heating. Under the heating of the atomizing core 13, the aerosol generated by the atomized liquid enters the user's oral cavity through the air passage and the air outlet 11c.

[0055] In related technologies, the air tube is typically inserted into the receiving cavity from the first side. That is, the second and first tube segments enter the receiving cavity sequentially from the first side. This requires the outer contour dimension of the second segment of the air tube to be smaller than the width of the receiving cavity; otherwise, the air tube cannot enter the receiving cavity. However, for some ultra-thin atomizers, the narrower width of the shell makes it impossible to insert the air tube from the first side. Additionally, for some air tubes with a larger outer contour dimension of the second tube segment to accommodate a larger atomizing coil, it is also impossible to insert them from the first side of the receiving cavity.

[0056] The technical solution of the atomizer 10 in this application embodiment is to construct an installation space 11a2 that communicates with the liquid storage space 11a1 by recessing part of the inner wall of the receiving cavity 11a. Even if the housing 11 is narrowed, the housing 11 still has a large installation space 11a2 to accommodate the second section 122 of the vent pipe 12. Meanwhile, the housing 11 has a mounting port 11b located on one side of the receiving cavity 11a along the first direction and communicating with the mounting space 11a2. During assembly, the first tube segment 121 and the second tube segment 122 enter the receiving cavity sequentially through the mounting port 11b. That is, the first tube segment 121, with a smaller outer contour size, enters the receiving cavity 11a first, followed by the second tube segment 122, with a larger outer contour size. At least a portion of the structure of the second tube segment 122 is constrained within the mounting space 11a2. Compared to the vent tube in related technologies, which enters from the first side of the receiving cavity, the vent tube 12 in this embodiment actually enters from the second side X2 of the receiving cavity 11a. This allows at least a portion of the structure of the second tube segment 122 to extend into and be constrained within the mounting space 11a2, even with a narrower housing 11. Therefore, the atomizer 10 of this embodiment can meet the requirements for ultra-thin design.

[0057] In some embodiments, please refer to Figure 1 and Figure 7The inner wall of the receiving cavity 11a includes a first inner wall 11a3 and a second inner wall 11a4 located on opposite sides of the receiving cavity 11a along the second direction. The first inner wall 11a3 and the second inner wall 11a4 can be recessed to form an installation space 11a2, wherein the second direction intersects the first direction.

[0058] In other words, the first inner wall 11a3 and the second inner wall 11a4 are recessed in a direction away from each other. When at least a part of the structure of the second tube segment 122 extends into the installation space 11a2, the part of the structure of the second tube segment 122 is located in the part of the structure of the first inner wall 11a3 and the second inner wall 11a4 respectively. As a result, the size of the shell 11 along the second direction can be further reduced, which is beneficial to achieving the ultra-thin design of the atomizer 10.

[0059] It is understood that the recessed portions of the first inner wall 11a3 and the second inner wall 11a4 form the installation space 11a2, while the non-recessed portions of the first inner wall 11a3 and the second inner wall 11a4 can form the liquid storage space 11a1. A portion of the liquid storage space 11a1 is located on the side of the installation space 11a2 away from the installation port 11b along the first direction. The liquid storage space 11a1 in this region is defined as the liquid storage sub-cavity. The liquid storage sub-cavity has a first dimension H1 (i.e., width dimension) along the first direction. The installation space 11a2 has a second dimension (not shown in the figure) along the first direction. The second dimension is larger than the first dimension, and the first dimension is smaller than the maximum outer contour dimension H2 of the second pipe segment 122. This causes at least a portion of the structure of the second pipe segment 122 to be constrained within the installation space 11a2, preventing the second pipe segment 122 from sliding from the installation space 11a2 into the liquid storage sub-cavity.

[0060] In other embodiments, only one of the first inner wall 11a3 and the second inner wall 11a4 may be recessed, while the other is not recessed.

[0061] For example, please refer to Figure 2 , Figure 3 , Figures 5 to 7 At least one side of the installation space 11a2 along the third direction can be opened to form an opening (not shown) communicating with the liquid storage space 11a1, and the liquid outlet 122a is exposed at the opening, wherein the third direction intersects with the second direction and the first direction respectively.

[0062] In other words, a portion of the liquid storage space 11a1 is located on at least one side of the installation space 11a2 along a third direction. When the second pipe section 122 is installed into the installation space 11a2, the liquid guide port 122a is located on one side of the second pipe section 122 along a third direction and faces the liquid storage space 11a1, so that the atomizing liquid can flow smoothly from the liquid guide port 122a to the atomizing core 13, ensuring atomization efficiency.

[0063] Please see Figure 2 and Figure 5 There can be two liquid guide ports 122a, located on opposite sides of the second pipe section 122. The installation space 11a2 is open on both opposite sides along the third direction, corresponding one-to-one with the two liquid guide ports 122a. That is, a portion of the liquid storage space 11a1 is located on opposite sides of the installation space 11a2 along the third direction, thereby further ensuring sufficient liquid supply to the atomizing core 13 and preventing the atomizing core 13 from burning dry. In other embodiments, there can be only one liquid guide port 122a, with one side of the installation space 11a2 open along the third direction.

[0064] For example, please refer to Figure 2 , Figures 5 to 7 The portion of the second pipe section 122 located within the installation space 11a2 forms a gap region on the periphery of the installation space 11a2 between the portion of the second pipe section 122 located within the installation space 11a2 and the inner wall of the receiving cavity 11a. The housing 11 also includes a rib 111 protruding from the inner wall of the receiving cavity 11a, and the rib 111 is located in the gap region.

[0065] When at least a portion of the structure of the second pipe section 122 is constrained within the installation space 11a2, part of the structure of the second pipe section 122 is located within the recessed area, while part of the structure is located outside the recessed area. The structure located outside the recessed area forms a certain angle space with the inner wall of the receiving cavity 11a. This angle space is the interval area. By setting the rib 111 in the interval area, the atomizing liquid can be prevented from forming a capillary effect in the interval area, which would prevent the atomizing liquid from flowing and thus reduce the utilization rate of the atomizing liquid.

[0066] Figure 5 In the atomizer 10 shown, ribs 111 are provided on both sides of the recessed area along the third direction.

[0067] In some embodiments, please refer to Figure 1 , Figure 5 and Figure 6 The second pipe segment 122 may include an extension segment 1221 and a connecting segment 1222 connected to the first pipe segment 121. The connecting segment 1222 gradually tapers from one end away from the first pipe segment 121 to one end close to the first pipe segment 121. At least a portion of the structure of the extension segment 1221 and at least a portion of the structure of the connecting segment 1222 are constrained within the installation space 11a2.

[0068] In other words, from the end away from the first pipe segment 121 to the end close to the first pipe segment 121, the outer contour size of the connecting sub-segment 1222 gradually decreases, and the connecting sub-segment 1222 is roughly in the shape of a frustum with internal penetration.

[0069] By gradually contracting the connecting segment 1222, a smooth transition can be achieved between the extension segment 1221 of the second pipe segment 122 and the first pipe segment 121, reducing turbulence and resistance. The aerosol flows more smoothly within the vent pipe 12, which helps to stably discharge the aerosol, thereby reducing the generation of condensate and improving the user's suction experience.

[0070] Please see Figure 1 , Figure 5 and Figure 6 In some embodiments, a portion of the structure of the extension segment 1221 and a portion of the structure of the connecting segment 1222 are located within the mounting space 11a2. Alternatively, the entire structure of the extension segment 1221 and the entire structure of the connecting segment 1222 may be located within the mounting space 11a2. Or, a portion of the structure of the extension segment 1221 and the entire structure of the connecting segment 1222 may be located within the mounting space 11a2. It is also possible that the entire structure of the extension segment 1221 and a portion of the structure of the connecting segment 1222 are located within the mounting space 11a2.

[0071] Please see Figure 5 and Figure 6 The extension section 1221 has a liquid guide port 122a. The atomizing core 13 is located inside the extension section 1221. The atomizing core 13 heats the atomizing liquid to generate an aerosol, which is released into the extension section 1221 and flows from the connecting section 1222 to the first pipe section 121.

[0072] For example, please refer to Figure 5 and Figure 7 The recessed portion of the inner wall may include a first wall surface 11a21 and a second wall surface 11a22 located on the side of the first wall surface 11a21 facing away from the mounting opening 11b along the first direction. The shape of the first wall surface 11a21 matches the shape of the extension segment 1221, and the shape of the second wall surface 11a22 matches the shape of the connecting segment 1222.

[0073] In other words, the outline shape and curvature change of the first wall 11a21 are complementary to the outer outline of the extended sub-segment 1221, and the outline shape and curvature change of the second wall 11a22 are complementary to the outer outline of the connecting sub-segment 1222.

[0074] For example, Figure 5 and Figure 7 Since the outer contour of the extended segment 1221 is cylindrical, the first wall surface 11a21 is a curved surface that matches it. And since the outer contour of the connecting segment 1222 is frustum-shaped, the second wall surface 11a22 is an inclined curved surface that matches it.

[0075] By matching the shape of the first wall 11a21 with the shape of the extension segment 1221 and the shape of the second wall 11a22 with the shape of the connecting segment 1222, the displacement of the air tube 12 within the receiving cavity 11a can be limited, ensuring the stability of its working position. At the same time, redundant space caused by shape mismatch can be avoided, making the overall structure of the atomizer 10 more compact, so as to further realize the thinning of the atomizer 10.

[0076] In some embodiments, please refer to Figure 2 and Figure 4 The housing 11 has an air outlet 11c and a first liquid storage tank 11d. The air outlet 11c and the first liquid storage tank 11d can be located on opposite sides of the receiving cavity 11a along the first direction, and both are in fluid communication with the vent pipe 12.

[0077] In other words, when the user inhales the atomizer 10, the first liquid storage tank 11d is located below the air pipe 12 along the direction of gravity. The condensate generated in the airflow channel can flow to the first liquid storage tank 11d under the action of gravity, so as to achieve a better anti-leakage effect.

[0078] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 4 The housing 11 may have a connecting channel 11e and a first connecting port 11f and a second connecting port 11g respectively connected to the connecting channel 11e. The connecting channel 11e is located on the side of the mounting port 11b away from the receiving cavity 11a along a first direction, and is in fluid communication with the air pipe 12 through the first connecting port 11f. The atomizer 10 may also include a sensor mounting member 14 disposed in the housing 11 and having an airflow detection port 14a. The airflow detection port 14a is in fluid communication with the connecting channel 11e through the second connecting port 11g.

[0079] Sensor mounting 14 is used to mount airflow sensor 30.

[0080] Specifically, in the aerosol generating device, the air outlet 11c, the airflow channel of the vent pipe 12, the first connecting port 11f, the connecting channel 11e, and the second connecting port 11g form an airflow path. During the user's suction process, a negative pressure will be generated on the airflow path in the aerosol generating device. After the airflow detection port 14a is fluidly connected to the connecting channel 11e through the second connecting port 11g, a negative pressure will also be generated in the sensor mounting component 14. Therefore, the airflow sensor 30 can achieve the purpose of detecting the negative pressure on the airflow path.

[0081] For example, please refer to Figure 1 and Figure 4The second connection port 11g can be located on the side of the sensor mounting member 14 close to the mounting port 11b along the first direction. The sensor mounting member 14 also has a second liquid storage tank 14b, which faces the second connection port 11g. That is, the second connection port 11g is located between the second liquid storage tank 14b and the connecting channel 11e, and on the projection plane perpendicular to the first direction, the projection of the second connection port 11g coincides with the projection of the second liquid storage tank 14b.

[0082] The second liquid storage tank 14b is used to store condensate. When the aerosol flows in the airflow channel of the vent pipe 12, condensate is generated. After the condensate enters the connecting channel 11e through the first connecting port 11f, it can drip into the second liquid storage tank 14b from the second connecting port 11g to achieve a better leak-proof effect.

[0083] Please continue reading. Figure 1 and Figure 4 The airflow detection port 14a is offset from the second connecting port 11g. In other words, the airflow detection port 14a avoids the second connecting port 11g, thereby preventing condensate from dripping directly from the second connecting port 11g into the airflow detection port 14a and affecting the operation of the airflow sensor 30.

[0084] For example, please refer to Figure 1 and Figure 4 The second liquid storage tank 14b can be located on one side of the airflow detection port 14a along the second direction, which intersects with the first direction. The sensor mounting component 14 also has a sensor mounting cavity (not shown in the figure) for mounting the airflow sensor 30. The sensor mounting cavity is located on the side of the second liquid storage tank 14b and the airflow detection port 14a along the first direction away from the second communication port 11g, which can prevent condensate from directly entering the sensor mounting cavity.

[0085] In an embodiment where the housing 11 has an air outlet 11c and a first liquid storage tank 11d, please refer to... Figure 1 , Figure 2 and Figure 4 The housing 11 may also include a protrusion located within the first liquid storage tank 11d and facing the mounting port 11b. The connecting channel 11e, the first connecting port 11f, and the second connecting port 11g are disposed on the protrusion, and the first connecting port 11f is located at the end of the protrusion facing the mounting port 11b.

[0086] In other words, the connecting channel 11e passes through the protruding post to form a first connecting port 11f and a second connecting port 11g at opposite ends of the protruding post.

[0087] Since the protrusion extends out of the first liquid storage tank 11d, when the user is pumping, the height of the first connecting port 11f is higher than the bottom wall of the first liquid storage tank 11d, thereby preventing the condensate stored in the first liquid storage tank 11d from entering the connecting port through the first connecting port 11f.

[0088] In some embodiments, please refer to Figures 3 to 7 The housing 11 includes an oil tank 112 with a receiving cavity 11a and an installation port 11b, and a bracket 113 with a first liquid storage tank 11d, a first connecting port 11f, a connecting channel 11e, and a second connecting port 11g. The bracket 113 is located on one side of the oil tank 112 along a first direction. It is understood that during the assembly process, the vent pipe 12 is first installed into the receiving cavity 11a of the oil tank 112, and then the oil tank 112 and the bracket 113 are connected.

[0089] For example, please refer to Figure 1 , Figures 3 to 5 The housing 11 also includes a nozzle 114 with an air outlet 11c. The nozzle 114 is located on the side of the oil tank 112 away from the support 113. The first section 121 of the vent pipe 12 is in fluid communication with the nozzle 114 to guide the aerosol to the air outlet 11c.
