Description

Technical Field

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

[0002] The atomizing device may include an atomizing core and an airflow sensor. The airflow sensor generates a control signal based on the user's inhalation action. The control signal is used to control the atomizing core to heat the atomizing matrix to generate an aerosol or to stop heating. In related technologies, the airflow in the main airflow channel can easily interfere with the airflow in the airflow sensing channel, resulting in low sensitivity of the airflow sensor and affecting the user experience. Utility Model Content

[0003] This application provides an atomizer and atomizing device that can solve the technical problem of low sensitivity of airflow sensors.

[0004] To address the aforementioned technical problems, this application provides an atomizer comprising an atomizing component, a top cover, and a base. The base is connected to one end of the top cover along a first direction, and the atomizing component is disposed between the top cover and the base. The atomizing component has an atomizing chamber and includes an atomizing core disposed within the atomizing chamber. The atomizing core is used to heat the atomizing matrix to generate an aerosol. The atomizer has an airflow sensing channel for the airflow sensor of the atomizer to sense changes in airflow within the atomizer. The end of the atomizing component near the base in the first direction cooperates with the base to form an airflow sensing chamber communicating with the atomizing chamber. The base has a first air inlet and an airflow sensing port. The first air inlet connects the airflow sensing chamber to the outside of the atomizer, and the airflow sensing port connects the airflow sensing chamber to the airflow sensing channel. The first air inlet, the airflow sensing chamber, and the atomizing chamber are connected along the first direction to form a main airflow channel, and the airflow sensing port is disposed on the side of the base perpendicular to the first direction.

[0005] In one embodiment, the atomizing assembly includes a first sealing element and an atomizing bracket. The atomizing chamber is disposed on the first sealing element, and the atomizing bracket has an installation hole. The atomizing core is installed in the installation hole. One end of the atomizing bracket in a first direction is positioned in the atomizing chamber, and the other end of the atomizing bracket is connected to the base to form an airflow sensing chamber.

[0006] In one embodiment, the atomizing bracket includes an interconnected mounting portion and an annular connecting portion, with a mounting hole disposed on the mounting portion; the base includes a fixing portion, with a first groove formed in the fixing portion, a first air inlet and an airflow sensing port disposed on the fixing portion and respectively communicating with the first groove; the annular connecting portion is sleeved on the outer periphery of the fixing portion, and the mounting portion is covered on one end of the fixing portion, the mounting portion and the annular connecting portion surrounding the first groove to form an airflow sensing cavity.

[0007] In one embodiment, the annular connecting portion is provided with a first airflow sensing hole, which connects the airflow sensing channel and the airflow sensing port.

[0008] In one embodiment, the atomizing bracket includes a positioning protrusion that protrudes from the inner wall of the annular connecting portion; in a first direction, the airflow sensing port extends toward the end of the fixing portion toward the mounting portion and passes through the end of the fixing portion, and the positioning protrusion engages with the airflow sensing port.

[0009] In one embodiment, the base has a receiving space, the fixing part is disposed in the receiving space, and the projection of the first sealing member along the first direction at least partially falls into the receiving space.

[0010] In one embodiment, the base includes a fixing part and a first partition, the fixing part being connected to one side of the first partition along a first direction; the first partition and the top cover form at least a portion of the sidewall of the airflow sensing channel, so as to form at least a portion of the airflow sensing channel between the base and the top cover.

[0011] In one embodiment, the base further includes a first sidewall, which surrounds the outer periphery of the first partition along a vertical direction of the first direction. The first sidewall and the first partition enclose a receiving space, and a fixing part is disposed in the receiving space. The atomizer includes a liquid suction element, which is disposed in the receiving space. The liquid suction element is provided with a first gap, and the first partition and the top cover enclose the first gap and form at least a portion of the airflow sensing channel.

[0012] In one embodiment, the atomizer includes at least two electrode components. The atomizing assembly has two mounting positions for mounting atomizing cores. The mounting positions are disposed within the atomizing chamber and are spaced apart along a second direction. An atomizing core is mounted on at least one mounting position. The atomizing core has a liquid guiding surface and an atomizing surface, and the atomizing surface has an electrode portion. At least two electrode components extend along a first direction and are spaced apart along a third direction. One end of each of the at least two electrode components is positioned between the two mounting positions so that the electrode component can contact the electrode portion of at least one atomizing core and form an electrical connection. At least one electrode component can contact the electrode portions of at least two atomizing cores.

[0013] In one embodiment, the fixing part has two electrode holes for inserting electrode components, and the two electrode holes are located on opposite sides of the first groove in the third direction.

[0014] Another aspect of this application provides an atomizing device, which includes an atomizer as described above and a liquid replenishment component. The liquid replenishment component is connected to the atomizer and is used to replenish the atomizing matrix to the atomizer.

[0015] In one embodiment, the atomizing device further includes an atomizing host, which is electrically connected to the atomizer; the atomizing host includes an airflow sensor, which senses changes in airflow in the atomizer through the airflow sensing channel of the atomizer.

[0016] The atomizer provided in this application has an atomizing component that, at one end near the base in a first direction, cooperates with the base to form an airflow sensing chamber that communicates with the atomizing chamber. The base has a first air inlet and an airflow sensing port. The first air inlet connects the airflow sensing chamber to the outside of the atomizer, and the airflow sensing port connects the airflow sensing chamber to the airflow sensing channel. The first air inlet, the airflow sensing chamber, and the atomizing chamber are connected along the first direction to form a main airway. The airflow sensing port is located on the side of the base perpendicular to the first direction, so that the main airway and the airflow sensing channel are relatively independent and extend in different directions. This can reduce the interference of the airflow in the main airway on the airflow in the airflow sensing channel, and the airflow sensor can more accurately sense the changes in the airflow in the atomizer, thereby improving the sensitivity of the airflow sensor.

[0034] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0035] In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified. The terms "first," "second," and "third" in the embodiments of this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of that feature. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movements between components in a specific orientation (as shown in the figures). If the specific orientation changes, the directional indication will also change accordingly. The terms "comprising" and "having," and any variations thereof, in the embodiments of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or components inherent to these processes, methods, products, or devices.

[0036] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0037] This application provides an atomizing device. Please refer to [link / reference]. Figures 1-5 The atomizing device 500 may include an atomizer 100 and a replenishment assembly 80. The replenishment assembly 80 is connected to the atomizer 100 and is used to replenish the atomizing matrix to the atomizer 100. When the atomizer 100 needs replenishment of the atomizing matrix, by adjusting the orientation of the atomizer 100, such as placing the atomizer 100 horizontally or with the mouthpiece 22 facing downwards, the atomizing matrix in the replenishment assembly 80 can flow to the atomizer 100 under the action of gravity. The atomizer 100 may have a pre-stored atomizing matrix, which is replenished by the replenishment assembly 80 after it is consumed; or, if the atomizer 100 does not have a pre-stored atomizing matrix, the replenishment assembly 80 injects the atomizing matrix into the atomizer 100 after the atomizer 100 is connected to the replenishment assembly 80. The atomizer 100 and the replenishment component 80 are set to be relatively independent. The replenishment component 80 can be placed outside the atomizer 100, thereby reducing the limitation of the atomizer 100 on the volume of the replenishment component 80. This allows the replenishment component 80 to have a relatively large capacity, which can store more atomizing matrix, thereby extending the service life of the atomizing device 500.

[0038] Please see Figure 1 , Figure 2 The atomizing device 500 may further include an atomizing host 90, with the atomizer 100 electrically connected to the atomizing host 90. The atomizing host 90 controls the operation of the atomizer 100. Exemplarily, the atomizer 100 and the atomizing host 90 may be electrically connected via electrodes. The atomizing host 90 may include a battery 91, a circuit board 92, and an airflow sensor 93. Both the circuit board 92 and the airflow sensor 93 are electrically connected to the battery 91. The airflow sensor 93 can generate a control signal based on the user's inhalation action, and the circuit board 92 can control the conduction state between the atomizer 100 and the battery 91 according to the control signal, thereby controlling the atomizer 100 to heat the atomizing matrix to generate an aerosol or to stop heating. The atomizer 100 and the atomizing host 90 may be fixedly connected, or they may be detachable connections such as snap-fit, screw-fit, adhesive, or magnetic connection. When the atomizer 100 and the atomizing host 90 are detachably connected, the atomizing host 90 can be used multiple times after replacing the atomizer 100, which helps reduce the user's operating costs.

[0039] The atomizer 100 has a first direction, a second direction, and a third direction that are different from each other. For example, the first direction may be... Figure 4 The positive or negative direction of the Z-axis, and the second direction can be Figure 4 The positive or negative direction of the X-axis, and the third direction can be Figure 5 The positive or negative direction of the Y-axis. Due to limitations in the manufacturing process, the parallelism or perpendicularity in this application may have a certain deviation, for example, ±5°. Please refer to... Figures 3-7 The atomizer 100 includes an atomizing component 10, a top cover 30, and a base 40. The base 40 is connected to one end of the top cover 30 along a first direction, and the atomizing component 10 is disposed between the top cover 30 and the base 40. The base 40 and the top cover 30 can be snap-fitted together, thereby facilitating the assembly and fixation of the atomizing component 10 between the top cover 30 and the base 40. The atomizing component 10 has an atomizing chamber 121. The atomizing component 10 includes an atomizing core 11, which is disposed in the atomizing chamber 121 and is used to heat the atomizing matrix to generate an aerosol. The atomizer 100 has an airflow sensing channel 46, which is used by the airflow sensor 93 of the atomizing host 90 to sense changes in airflow in the atomizer 100. When the atomizer 100 is connected to the atomizing host 90, the airflow sensor 93 senses the airflow changes in the atomizer 100 through the airflow sensing channel 46, so that the airflow sensor 93 can generate a control signal based on the user's inhalation action. The circuit board 92 can control the conduction state between the atomizing core 11 and the battery 91 according to the control signal, thereby controlling the atomizing core 11 to heat the atomizing matrix to generate aerosol or stop heating.

[0040] Please see Figures 3-7The atomizing component 10, at its end near the base 40 in the first direction, forms an airflow sensing chamber 45 that connects to the atomizing chamber 121. The base 40 has a first air inlet 432 and an airflow sensing port 433. The first air inlet 432 connects the airflow sensing chamber 45 to the outside of the atomizer 100, allowing external air to enter the airflow sensing chamber 45 through the first air inlet 432. The airflow sensing port 433 connects the airflow sensing chamber 45 to the airflow sensing channel 46, allowing the airflow sensor 93 to sense changes in airflow within the atomizer 100 through the airflow sensing port 433 and the airflow sensing channel 46. The first air inlet 432, the airflow sensing chamber 45, and the atomizing chamber 121 are connected along the first direction to form a main airflow channel 44. The airflow in the main airflow channel 44 can carry aerosol output. The airflow sensing port 433 is located on the side of the base 40 perpendicular to the first direction. The airflow sensing channel 46 can penetrate the atomizer 100 on the side perpendicular to the first direction. This configuration makes the main airway 44 and the airflow sensing channel 46 relatively independent and extend in different directions. This reduces the interference of the airflow in the main airway 44 on the airflow in the airflow sensing channel 46, allowing the airflow sensor 93 to more accurately sense changes in the airflow in the atomizer 100, thereby improving the sensitivity of the airflow sensor 93.

[0041] In one embodiment, such as Figures 8-10 As shown, the atomizing assembly 10 includes a first sealing element 12 and an atomizing bracket 13. An atomizing chamber 121 is disposed within the first sealing element 12. The first sealing element 12 can be made of a material with a certain elastic deformation capability, such as silicone or rubber. When the first sealing element 12 is interference-fitted into the atomizer 100, it undergoes elastic deformation, allowing it to seal the gap between the atomizing assembly 10 and other components, thereby enhancing the airtightness of the atomizer 100 and preventing leakage of the atomizing matrix. The atomizing bracket 13 has a mounting hole 134, and the atomizing core 11 is installed in the mounting hole 134. By mounting the atomizing core 11 to the first sealing element 12 via the atomizing bracket 13, the atomizing core 11 can be pre-assembled into the atomizing bracket 13. The atomizing bracket 13, acting as an intermediate carrier, can pre-fix the atomizing core 11 and form an assembly module, preventing displacement of the atomizing core 11 during assembly and improving assembly accuracy.

[0042] The first seal 12 can extend to the base 40 and connect with the base 40 to form an airflow sensing cavity 45, so that the first seal 12 can further seal the base 40, thereby preventing leakage of the atomized matrix.

[0043] Please see Figure 6In one embodiment, one end of the atomizing bracket 13 is positioned in the atomizing chamber 121 in the first direction, and the other end of the atomizing bracket 13 is connected to the base 40 to form an airflow sensing chamber 45. By connecting the atomizing bracket 13 to the base 40 to form the airflow sensing chamber 45, the assembly difficulty of forming the airflow sensing chamber 45 can be reduced due to the greater rigidity of the atomizing bracket 13 relative to the first sealing member 12, which is beneficial to improving assembly efficiency.

[0044] In one embodiment, such as Figures 6-15 As shown, the atomizing bracket 13 includes an interconnected mounting portion 131 and an annular connecting portion 132, with a mounting hole 134 disposed in the mounting portion 131. The base 40 includes a fixing portion 43. The fixing portion 43 has a first groove 431, a first air inlet 432 and an airflow sensing port 433 disposed in the fixing portion 43 and respectively communicating with the first groove 431. The annular connecting portion 132 can be inserted into the first groove 431, with the outer wall of the annular connecting portion 132 abutting against the inner wall of the first groove 431. The mounting portion 131 and the annular connecting portion 132 surround the first groove 431 to form an airflow sensing cavity 45, which can enhance the airtightness of the airflow sensing cavity 45 and help to further improve the sensitivity of the airflow sensor 93. Or, as Figure 7 As shown, the annular connecting portion 132 is sleeved on the outer periphery of the fixing portion 43, and the mounting portion 131 covers one end of the fixing portion 43. The inner wall of the annular connecting portion 132 abuts against the outer wall of the fixing portion 43. The mounting portion 131 and the annular connecting portion 132 surround the first groove 431 to form an airflow sensing cavity 45, which can enhance the airtightness of the airflow sensing cavity 45 and further improve the sensitivity of the airflow sensor 93. In addition, under the condition that the internal space of the first groove 431 is fixed, compared with the annular connecting portion 132 being inserted into the first groove 431, setting the annular connecting portion 132 on the outer periphery of the fixing portion 43 does not occupy the internal space of the first groove 431, which is conducive to increasing the volume of the airflow sensing cavity 45, thereby reducing the resistance of the airflow sensing cavity 45 to the gas and improving the taste of the aerosol.

[0045] In one embodiment, such as Figures 6-15 As shown, the base 40 has a receiving space 411, and the fixing part 43 is disposed in the receiving space 411. The projection of the first sealing member 12 along the first direction at least partially falls into the receiving space 411. With this arrangement, the atomizing matrix that seeps out from the gap between the atomizing bracket 13 and the first sealing member 12 can be stored in the receiving space 411, thereby reducing the possibility of atomizing matrix leakage.

[0046] The overlap between the annular connecting part 132 and the fixing part 43 in the first direction can be relatively small, which can save the amount of material used in the annular connecting part 132 and ensure that the annular connecting part 132 does not affect the connection between the airflow sensing port 433 and the airflow sensing channel 46.

[0047] Please see Figure 7 , Figure 13 , Figure 14 In one embodiment, the annular connecting portion 132 is provided with a first airflow sensing hole 137, which connects the airflow sensing channel 46 and the airflow sensing port 433. This arrangement results in a relatively large overlap between the annular connecting portion 132 and the fixing portion 43 in the first direction. The sidewall of the annular connecting portion 132 at the first airflow sensing hole 137 seals the outer periphery of the airflow sensing port 433, enhancing the airtightness of the airflow sensing cavity 45 and further improving the sensitivity of the airflow sensor 93.

[0048] The airflow sensing port 433 can be a through hole, and the first airflow sensing hole 137 communicates with the airflow sensing cavity 45 through the through hole. Alternatively, in one embodiment, such as Figure 14 , Figure 15 As shown, the airflow sensing port 433 is a slot with one end open in the first direction. The atomizing bracket 13 includes a positioning protrusion 133, which protrudes from the inner wall of the annular connecting portion 132. In the first direction, the airflow sensing port 433 extends toward the end of the fixing portion 43 toward the mounting portion 131 and passes through the end of the fixing portion 43, with the positioning protrusion 133 engaging with the airflow sensing port 433. This arrangement allows the positioning protrusion 133 to be inserted into the airflow sensing port 433 along its open end, facilitating the identification of the assembly direction and positioning of the atomizing bracket 13, thus improving assembly efficiency.

[0049] The base 40 or the top cover 30 may have a through hole in the vertical direction of the first direction to form at least a partial airflow sensing channel 46, so that the airflow sensor 93 can sense changes in airflow in the atomizer 100 through the airflow sensing channel 46. (See also...) Figure 6 , Figure 15 In one embodiment, the base 40 includes a first partition 42, and a fixing part 43 is connected along a first direction to the side of the first partition 42 facing the mounting part 131. The first partition 42 and the upper cover 30 form at least a portion of the sidewall of the airflow sensing channel 46, thereby forming at least a portion of the airflow sensing channel 46 between the base 40 and the upper cover 30. By providing the first partition 42 and the upper cover 30 to form at least a portion of the sidewall of the airflow sensing channel 46, at least a portion of the airflow sensing channel 46 can be formed between the base 40 and the upper cover 30 when they are assembled and connected. This eliminates the need to process through holes in the base 40 or the upper cover 30 to form at least a portion of the airflow sensing channel 46, simplifying the processing of the base 40 or the upper cover 30 and reducing costs.

[0050] The base 40 or the top cover 30 may have a ventilation slot open on one side. When the base 40 and the top cover 30 are assembled and connected, the base 40 or the top cover 30 surrounds the open side of the ventilation slot to form at least a partial airflow sensing channel 46. Compared with machining through holes in the base 40 or the top cover 30 to form at least a partial airflow sensing channel 46, machining the open slot is more convenient, which can simplify the machining of the base 40 or the top cover 30 and help reduce costs.

[0051] In one embodiment, such as Figure 6 , Figure 7 , Figure 15 , Figure 16 As shown, the base 40 includes a first sidewall 41. The first sidewall 41 surrounds the outer periphery of the first partition 42 along a first direction perpendicular to it. The first sidewall 41 and the first partition 42 enclose a receiving space 411, and a fixing part 43 is disposed in the receiving space 411. The atomizer 100 includes a liquid suction member 70, which is housed in the receiving space 411. The liquid suction member 70 can be made of porous fiber, such as natural fiber-based, synthetic fiber-based, carbon-based fiber, inorganic fiber, or composite fiber. The liquid suction member 70 is used to absorb the atomizing matrix seeping from the atomizing core 11 to prevent leakage of the atomizing matrix. The liquid suction member 70 is provided with a first gap 71, which is enclosed by the first partition 42 and the upper cover 30 to form at least a partial airflow sensing channel 46. The sidewall of the first gap 71 of the liquid suction component 70 forms at least part of the sidewall of the airflow sensing channel 46. The base 40 or the top cover 30 may not have an open slot, which further simplifies the processing of the base 40 or the top cover 30 and helps to reduce costs.

[0052] In one embodiment, such as Figure 9 As shown, the atomizing assembly 10 has two mounting positions 14 for mounting atomizing coils 11. The two mounting positions 14 are spaced apart along a second direction. Each mounting position 14 can mount one atomizing coil 11. The atomizing assembly 10 has two mounting positions 14, so that the two atomizing coils 11 can form a relatively independent module. The two atomizing coils 11 can be assembled into the body of the atomizer 100 with only one operation, realizing the modular assembly of the atomizing assembly 10 and improving the assembly efficiency of the atomizer 100.

[0053] Please see Figures 3-10In one embodiment, at least one mounting position 14 is equipped with an atomizing core 11. The number of atomizing cores 11 can be one or two. When the number of atomizing cores 11 is one, the mounting position 14 without an atomizing core 11 can be blocked. The atomizing core 11 has a liquid guiding surface 113 and an atomizing surface 114. The liquid guiding surface 113 is used to transfer the atomizing matrix to the atomizing surface 114, where the atomizing matrix can generate an aerosol. The atomizing surface 114 can be a plane or a curved surface, such as a cylindrical curved surface. The atomizing surface 114 is provided with an electrode portion 117. At least two electrode members 60 extend along a first direction and are spaced apart along a third direction. The electrode members 60 are arranged to extend along the first direction such that the extension direction of the electrode members 60 can be parallel to the flow direction of the airflow at the atomizing core 11, and the electrode members 60 will not obstruct the airflow and affect the taste of the aerosol. At least two electrode elements 60 are positioned at one end between two mounting positions 14 so that the electrode element 60 can contact and form an electrical connection with the electrode portion 117 of at least one atomizing core 11. At least one electrode element 60 can contact the electrode portions 117 of at least two atomizing cores 11. This arrangement allows at least two electrode portions 117 to share one electrode element 60, reducing the number of electrode elements 60 and thus reducing the structural complexity of the atomizer 100.

[0054] The atomizing core 11 can be prepared by metal doping in a medium (such as porous ceramic or silicon wafer), so that it can both transfer the atomizing matrix and generate heat to heat the atomizing matrix.

[0055] Please see Figures 6-11 In one embodiment, the atomizing core 11 includes a liquid guiding element 111 and a heating element 112. The liquid guiding element 111 is used to transfer the atomizing matrix to the heating element 112, and the heating element 112 is used to generate heat when energized, thereby atomizing the atomizing matrix. The liquid guiding element 111 is a porous medium, such as porous ceramic, porous metal, or porous glass. The liquid guiding element 111 is mounted at the mounting position 14. A liquid guiding surface 113 and an atomizing surface 114 are disposed on the liquid guiding element 111. The heating element 112 is disposed on the atomizing surface 114. The heating element 112 may be formed on the atomizing surface 114 of the liquid guiding element 111 by electroplating, or the heating element 112 may be made by co-firing a heating wire / mesh with ceramic, so that the heating element 112 is partially exposed on the atomizing surface 114 of the liquid guiding element 111. The atomizing matrix can be transferred from the liquid guiding surface 113 to the atomizing surface 114, and the heating element 112 can heat the atomizing matrix to generate an aerosol.

[0056] Please see Figures 5-8In one embodiment, the fixing part 43 has two electrode holes 434 for inserting the electrode component 60. The two electrode holes 434 are located on opposite sides of the first groove 431 in the third direction. By setting the electrode holes 434 on the groove wall of the first groove 431, the groove wall of the first groove 431 can both enclose and form the airflow sensing cavity 45 and fix the electrode component 60. The fixing part 43 achieves functional reuse, eliminating the need for additional fixing components for the electrode component 60, reducing the number of components, and further reducing the structural complexity of the atomizer 100.

[0057] Please see Figures 5-9 In one embodiment, the first sealing member 12 is provided with a liquid inlet 122, a first output hole 123, and a second air inlet 124 communicating with the atomizing chamber 121. The first output hole 123 and the second air inlet 124 are respectively disposed at opposite ends of the first sealing member 12 along a first direction. The projection of the first output hole 123 along the first direction at least partially falls into the second air inlet 124. External air can enter the atomizing chamber 121 through the second air inlet 124 to drive the flow of aerosol generated in the atomizing chamber 121. The projection of the first output hole 123 along the first direction at least partially falls into the second air inlet 124, so that the first output hole 123 and the second air inlet 124 can form a straight airflow channel in the first direction, which helps to reduce the flow resistance of aerosol and prevents the aerosol from forming eddies in the atomizing chamber 121, affecting the taste. The liquid inlet 122 is disposed on the side wall of the first sealing member 12 perpendicular to the first direction. The liquid inlet 122 is used to supply the atomizing matrix.

[0058] In one embodiment, such as Figures 5-9 As shown, a liquid guiding component 111 is disposed in the atomizing chamber 121. The liquid guiding component 111 has a liquid guiding surface 113 and an atomizing surface 114. The liquid guiding surface 113 is exposed to the liquid inlet 122, and the atomizing surface 114 faces the interior of the atomizing chamber 121. The atomizing matrix can be transferred from the liquid guiding surface 113 to the atomizing surface 114, and the aerosol generated by the heating element 112 is output through the first output port 123. The atomizing surfaces 114 of both liquid guiding components 111 are planar and perpendicular to the second direction. By setting the atomizing surface 114 perpendicular to the second direction, the atomizing surface 114 is parallel to the first direction. The liquid guiding component 111 will not block the atomized aerosol produced by the atomizing surface 114, and the aerosol can be output more smoothly through the first output port 123, further preventing the aerosol from forming eddies in the atomizing chamber 121 and affecting the taste.

[0059] Please see Figures 5-14In one embodiment, the atomizing bracket 13 has a mounting hole 134, a second output hole 136, and a third air inlet 135 that are interconnected. The second output hole 136 and the third air inlet 135 are respectively disposed at opposite ends of the atomizing bracket 13 along a first direction. The second output hole 136 is connected to the first output hole 123, allowing aerosol to be output through the second output hole 136 and the first output hole 123. The mounting hole 134 is disposed on the side wall of the atomizing bracket 13 perpendicular to the first direction and is connected to the liquid inlet hole 122. The liquid guide 111 is installed in the mounting hole 134. The liquid guide 111 is installed on the first sealing member 12 through the atomizing bracket 13. The two liquid guides 111 can be first assembled to the atomizing bracket 13 and then installed to the first sealing member 12 through the atomizing bracket 13, so that the two liquid guides 111 form an assembly module, which is beneficial to improving assembly efficiency.

[0060] In one embodiment, such as Figure 4 , Figure 5 As shown, the upper cover 30 has an installation space 31, the first sealing member 12 is installed in the installation space 31, and the fixing part 43 presses and fixes the atomizing core 11 in the installation space 31. With this configuration, the upper cover 30 and the base 40 can cooperate to prevent the atomizing core 11 from shifting, thereby enhancing the stability of the atomizing core 11 during operation.

[0061] Please see Figure 4 , Figure 5 In one embodiment, the upper cover 30 is provided with a third output hole 32, and each output hole and the air inlet are interconnected. The projection of the third output hole 32 along the first direction falls at least partially into the first groove 431, so that each output hole and each air inlet can form a straight airflow channel in the first direction, which is beneficial to reduce the flow resistance of aerosol and can prevent the aerosol from forming eddies in the atomization chamber 121 and affecting the taste.

[0062] In one embodiment, such as Figures 1-5As shown, the atomizer 100 also includes a housing assembly 20 and a second seal 50. The housing assembly 20 includes a liquid reservoir 21, a mouthpiece 22, and an airway tube 23. The mouthpiece 22 is connected to one end of the liquid reservoir 21, and the top cover 30 is installed inside the liquid reservoir 21. One end of the airway tube 23 is connected to the mouthpiece 22, and the other end of the airway tube 23 is connected to the third output hole 32 on the top cover 30, so that the aerosol can be output through the airway tube 23 and the mouthpiece 22. The airway tube 23 extends in a first direction, so that the first output hole 123 and the airway tube 23 can form a straight airflow channel in the first direction, which helps to reduce the flow resistance of the aerosol and prevents the aerosol from forming eddies in the atomization chamber 121, affecting the taste. The top cover 30, the liquid storage shell 21, the nozzle 22, and the air passage 23 enclose a liquid storage chamber 211. The liquid storage chamber 211 can communicate with the liquid replenishment component 80 through the connecting holes on the top cover 30 and the base 40, so that the liquid replenishment component 80 can replenish the atomizing matrix to the liquid storage chamber 211. The liquid storage shell 21, the nozzle 22, and the air passage 23 can be connected as a single unit or can be multiple relatively independent separate units. A second sealing element 50 is disposed between the top cover 30 and the liquid storage shell 21 and the air passage 23 to enhance the airtightness of the liquid storage chamber 211.

[0063] Please see Figure 6 , Figure 7 In one embodiment, a second airflow sensing hole 412 and a third airflow sensing hole 212 are respectively provided on the first sidewall 41 and the liquid storage shell 21. The second airflow sensing hole 412 is connected to the first gap 71. The second airflow sensing hole 412 and the third airflow sensing hole 212 form a partial airflow sensing channel 46. The airflow sensing channel 46 passes through the atomizer 100 at the third airflow sensing hole 212, so that the airflow sensor 93 can sense the airflow changes in the atomizer 100 through the airflow sensing channel 46.
