[0031] The present application is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0032] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various implementations, and the operational steps involved in each embodiment may be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a particular embodiment and do not imply a required composition and / or sequence.

[0033] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0034] The atomizer provided in this application is used to heat and atomize a matrix liquid to produce an aerosol for inhalation by the user. The atomizer includes a housing, a first seal, and an atomizer core. The first seal and the atomizer core are both disposed within the housing, with the first seal dividing the interior space of the housing into a liquid storage chamber and an air inlet chamber. The liquid storage chamber is used to store the matrix liquid, and the atomizer core is disposed within the liquid storage chamber and is used to heat and atomize the matrix liquid flowing from the liquid storage chamber into the atomizer core. One end of the atomizer core is connected to a mouthpiece on the housing for inhalation by the user, and the other end is connected to the air inlet chamber. The aerosol produced by the atomization of the matrix liquid flows to the mouthpiece along with the airflow for inhalation by the user. A liquid blocking structure is provided on the first sealing member at a position corresponding to the liquid inlet of the atomizer core. The liquid blocking structure partially blocks the liquid inlet in the lateral direction. When the matrix liquid in the liquid storage chamber flows into the atomizer core through the liquid inlet, the liquid blocking structure changes the flow rate and / or pressure of the matrix liquid in front of the liquid inlet, so that the flow of the matrix liquid is adapted to the heating and atomization process of the atomizer core, thereby preventing part of the matrix liquid from leaking from the atomizer core toward the nozzle without being atomized due to excessive flow rate and / or pressure.

[0035] The following describes some embodiments of the atomizer and atomization device provided by the present application in conjunction with the accompanying drawings.

[0036] In an embodiment of the first aspect of the present application, Figure 1 、 Figure 2 and Figure 3As shown, the atomizer 100 includes a housing 11 , a first sealing member 12 and an atomizing core 13 . The housing 11 has a suction nozzle 1111 at one end thereof along the first direction, the suction nozzle 1111 being in communication with the outside, and an exhaust pipe 1112 in communication with the suction nozzle 1111 being provided inside the housing 11; the housing 11 has an interior space therein, the first sealing member 12 being located inside the housing 11 and dividing the interior space therein into a liquid storage chamber 1113 and an air inlet chamber, the liquid storage chamber 1113 being used to store matrix liquid, and the air inlet chamber being used to allow air to flow in; the first sealing member 12 is provided with a first mounting hole 121 which passes through in the first direction, and the atomizer core 13 is disposed in the liquid storage chamber 1113 along the first direction, one end of the atomizer core 13 being in communication with the exhaust pipe 1112, and the other end extending into the first mounting hole 121 of the first sealing member 12, and the atomizer core 13 being sealedly connected to the first mounting hole 121, so as to isolate the liquid storage chamber 1113 from the air inlet chamber, thereby preventing the matrix liquid in the liquid storage chamber 1113 from leaking into the air inlet chamber. Among them, at least one liquid inlet 1311 is opened on the side wall of the atomizer core 13, and the matrix liquid in the liquid storage chamber 1113 can flow into the atomizer core 13 through the liquid inlet 1311 and be heated and atomized; the end of the first sealing member 12 facing the suction nozzle 1111 has a liquid blocking structure 122, that is, the liquid blocking structure 122 is located in the liquid storage chamber 1113, and at least one liquid inlet 1311 is correspondingly arranged with the liquid blocking structure 122, and on the side of the atomizer core 13, the liquid inlet 1311 is partially blocked by the liquid blocking structure 122, so that the liquid blocking structure 122 blocks part of the liquid from entering the liquid inlet 131. The matrix liquid flowing into the atomizer core 13 from the front changes the flow rate and / or pressure in front of the liquid inlet 1311, so that the flow rate and / or pressure of the matrix liquid flowing into the liquid inlet 1311 are adapted to the heating process of the atomizer core 13, thereby fully heating and atomizing the matrix liquid flowing into the atomizer core 13, and preventing part of the matrix liquid from being completely atomized from leaking from the atomizer core 13 and leaking out from the suction nozzle 1111 due to excessive flow rate and / or pressure at the liquid inlet 1311, thereby preventing the leakage of matrix liquid from affecting the user experience and also reducing the waste of matrix liquid.

[0037] It is understandable that in existing atomizers, in order to improve the atomization efficiency, the opening of the liquid inlet on the atomizer core is relatively large so that the matrix liquid can fully contact the heating area inside the atomizer core. However, since the matrix liquid in the liquid storage chamber has a certain pressure, when the pressure in front of the liquid inlet is too large, the flow rate of the matrix liquid will be further accelerated. Once it exceeds the atomization capacity of the atomizer core, part of the matrix liquid will not be atomized in time and will leak from the inside of the atomizer core to the nozzle under the action of pressure, and then leak outward, affecting the user's normal inhalation.

[0038] In this embodiment, the internal structure of the atomizer is improved and optimized. By providing a liquid blocking structure 122 on the first sealing member 12 connected to the atomizer core 13, the liquid inlet 1311 of the atomizer core 13 is partially blocked laterally by the liquid blocking structure 122, thereby reducing the liquid flow rate and pressure of the atomizer core 13 in front of the liquid inlet 1311, thereby reducing the possibility of the matrix liquid at the liquid inlet 1311 leaking through the atomizer core 13 without being atomized, thereby improving the problem of matrix liquid leaking through the suction nozzle 1111, which is beneficial to improving the user experience, while also improving the atomization efficiency and reducing the waste of matrix liquid.

[0039] It should be noted that in this embodiment, the shape and size of the liquid retaining structure 122 can be reasonably set according to the shape and size of the liquid inlet 1311, the power of the atomizer core 13, the properties and storage capacity of the matrix liquid, etc., so that the flow rate and pressure in front of the liquid inlet 1311 are compatible with the atomization process of the atomizer core 13. The first sealing member 12 can be a flexible member to facilitate sealing.

[0040] In addition, the number of the liquid inlet 1311 and the liquid blocking structure 122 can be one or more, and can be set according to specific assembly requirements and usage needs.

[0041] In a further embodiment of the present application, Figure 3 and Figure 4 As shown, in the lateral direction of the atomizer core 13, a first spacing L exists between the liquid blocking structure 122 and the outer wall of the atomizer core 13, that is, the liquid blocking structure 122 does not contact the outer wall of the atomizer core 13. A liquid inlet channel can be formed between the liquid blocking structure 122 and the corresponding liquid inlet 1311. The matrix liquid can flow directly into the atomizer core 13 from the area of the liquid inlet 1311 not blocked by the liquid blocking structure 122, or it can bypass the liquid blocking structure 122 and flow into the atomizer core 13 through the liquid inlet channel. This ensures that the flow rate of the matrix liquid flowing into the atomizer core 13 through the liquid inlet 1311 remains substantially consistent, thereby avoiding affecting the normal atomization operation of the atomizer core 13. In the area of the liquid inlet 1311 blocked by the liquid blocking structure 122, the matrix liquid needs to change its flow direction to bypass the liquid blocking structure 122, thereby reducing the frontal impact and pressure, allowing the matrix liquid to flow more smoothly into the atomizer core 13.

[0042] Furthermore, if Figures 3 to 5 As shown, the liquid inlet 1311 includes a shielding area 1312 and an exposed area 1313 . The shielding area 1312 is the area directly facing the liquid blocking structure 122 and shielded, and the area not shielded by the liquid blocking structure 122 is the exposed area 1313 .

[0043] Among them, in a specific implementation, in the first direction, the size of the liquid inlet 1311 is larger than the size of the liquid blocking structure 122, and the exposed area 1313 is located at the end of the shielding area 1312 close to the mouthpiece 1111, that is, the shielding area 1312 is further away from the mouthpiece 1111 relative to the exposed area 1313. It can be understood that, under normal circumstances, the first direction is the height direction of the atomizer 100. Under the influence of gravity, the closer to the bottom of the liquid storage chamber 1113, the greater the pressure of the matrix liquid, that is, the pressure of the matrix liquid in the shielding area 1312 is greater than the pressure in the exposed area 1313. The position of the liquid inlet 1311 away from the mouthpiece 1111 is blocked by the liquid blocking structure 122 to reduce the liquid pressure on the front of the position, so that the matrix liquid can flow into the atomization core 13 more smoothly.

[0044] In another specific implementation, Figure 4 and Figure 5 In the example, in the circumferential direction of the atomizer core 13, the size of the liquid inlet 1311 is smaller than the size of the liquid blocking structure 122, so that the areas at the same height in the liquid inlet 1311 are blocked in the same manner, that is, the areas at the same height are all blocked or exposed, so as to prevent local pressure imbalance in the areas at the same height in the liquid inlet 1311 from accelerating the leakage of the matrix liquid.

[0045] Furthermore, if Figure 4 and Figure 5 In the example, the area of the shielding region 1312 of the liquid inlet 1311 accounts for 2 / 3 to 3 / 4 of the total area of the liquid inlet 1311, so as to effectively alleviate the impact and pressure on the front of the liquid inlet 1311, and at the same time, the influence of the liquid blocking joint on the flow of the liquid inlet 1311 can be minimized. In conjunction with the liquid inlet channel between the liquid blocking structure 122 and the atomizer core 13, the flow of the liquid inlet 1311 is basically the same as the flow when the liquid blocking structure 122 is not provided, so as to meet normal atomization operation and the user's inhalation needs.

[0046] In a further embodiment of the present application, Figures 4 to 6As shown, the atomizer core 13 adopts a cylindrical structure. Correspondingly, the side of the liquid-blocking structure 122 facing the atomizer core 13 has a curved surface structure 1221 that is compatible with the atomizer core 13, and the curved surface structure 1221 is arranged coaxially with the atomizer core 13. That is, from the perspective along the first direction, the circle where the curved surface structure 1221 is located is concentric with the cylindrical atomizer core 13. At this time, the distance between any position on the curved surface structure 1221 and the corresponding position of the liquid inlet 1311 of the atomizer core 13 is equal, so as to prevent excessive changes in local flow rate or pressure due to changes in the spacing. At the same time, the curved surface structure 1221 can also guide the matrix liquid, which is conducive to alleviating liquid flow impact and turbulence, so that the matrix liquid that bypasses the liquid-blocking structure 122 and flows into the liquid inlet 1311 from the liquid inlet channel can flow more smoothly, which is conducive to preventing matrix liquid leakage.

[0047] In a further embodiment of the present application, Figure 4 and Figure 5 As shown, in the first direction, the end of the liquid inlet 1311 close to the suction nozzle 1111 has a first arcuate edge 1314, and correspondingly, the end of the liquid blocking structure 122 close to the suction nozzle 1111 has a second arcuate edge 1222; the center of the first arcuate edge 1314 and the center of the second arcuate edge 1222 are located on the same side, that is, the first arcuate edge 1314 and the second arcuate edge 1222 are concave in the same direction, for example Figure 5 In the example shown in FIG, in the first direction, the first arcuate edge 1314 and the second arcuate edge 1222 are both recessed toward the nozzle 1111, with their centers located on the side away from the nozzle 1111. This allows the exposed area 1313 of the liquid inlet 1311 to have a relatively smooth shape, which facilitates a smooth flow of the matrix liquid as it flows into the liquid inlet 1311. The radius of the second arcuate edge 1222 is greater than or equal to the radius of the first arcuate edge 1314, so that the contour of the boundary between the exposed area 1313 of the liquid inlet 1311 and the obstructed area 1312 is relatively smooth. It is understood that when the radius of the second arcuate edge 1222 is smaller than the radius of the first arcuate edge 1314, an unobstructed area will appear on one or both sides of the liquid inlet 1311 in the circumferential direction. This area is in the form of an elongated strip or spike, which can easily cause an abnormal increase in local pressure and an increase in liquid flow rate, thereby causing some matrix liquid in the corresponding area to leak from the inside of the atomizer core 13 to the nozzle 1111 without being atomized. The configuration in this embodiment can effectively alleviate the above-mentioned problems and achieve a better anti-leakage effect.

[0048] The first arc edge 1314 and the second arc edge 1222 can both be configured as a semicircle, a major arc, or a minor arc.

[0049] In a further embodiment of the present application, Figure 3 and Figure 4As shown, the atomizer core 13 includes an atomizer core sleeve 131, an atomizer core body 132 and a liquid absorption structure 133. The atomizer core sleeve 131 extends along the first direction, one end is connected to the exhaust pipe 1112, and the other end is sealed with the first mounting hole 121, so as to connect the suction nozzle 1111 with the air inlet cavity through the atomizer core sleeve 131 and the exhaust pipe 1112. The atomizer core body 132 and the liquid absorption structure 133 are arranged in the atomizer core sleeve 131, and the atomizer core body 132 has an air passage running through it in the first direction; the liquid absorption structure 133 covers the outer surface of the atomizer core body 132. A liquid inlet 1311 is provided on the sidewall of the atomizer core sleeve 131, corresponding to the atomizer core body 132. The matrix liquid in the liquid storage chamber 1113 enters the atomizer core sleeve 131 through the liquid inlet 1311, is adsorbed on the liquid absorbing structure 133, and then penetrates through the liquid absorbing structure 133 to different areas on the outer surface of the atomizer core body 132, thereby ensuring more uniform heating of the atomizer core body 132 and improving atomization efficiency. The matrix liquid is heated and atomized to produce an aerosol, which is carried by the airflow in the air passage toward the mouthpiece 1111 for inhalation by the user.

[0050] Among them, Figure 3 In the example, the end of the atomizer core sleeve 131 away from the inhaler nozzle 1111 extends into the first mounting hole 121 of the first sealing member 12. The inner sidewall of the first mounting hole 121 has a plurality of raised structures for sealing. The raised structures squeeze and form an interference fit with the outer sidewall of the portion of the atomizer core sleeve 131 extending into the first mounting hole 121, thereby achieving a sealed connection. In addition, the atomizer core body 132 has a conductive portion 1321 (e.g., a pin structure). The conductive portion 1321 extends outside the atomizer core sleeve 131 to connect to the electrode. When in use, the electrode can be used to form an electrical connection with the power supply device, thereby supplying power to the atomizer core body 132.

[0051] In a further embodiment of the present application, Figure 3 、 Figure 7 and Figure 8As shown, the housing 11 has an air intake duct 1115, one end of which is connected to the air intake chamber and the other end is connected to the outside atmosphere. The atomizer 100 also includes a support 14. The support 14 is arranged in the air intake chamber of the housing 11, and an air guide cavity 141 is formed in the support 14. A first connecting port 142 and a second connecting port 143 are provided on the support 14; the two ends of the first connecting port 142 are respectively connected to the air guide cavity 141 and the end of the atomizer core 13 away from the inhaler nozzle 1111, and the two ends of the second connecting port 143 are respectively connected to the air guide cavity 141 and the air intake chamber, so as to realize the connection between the air intake duct 1115 and the atomizer core 13 through the air intake cavity and the air guide cavity 141 in the support 14. After being guided by the air guide cavity 141, the intake air flow enters the interior of the atomizer core 13 from the end of the atomizer core 13 away from the inhaler nozzle 1111, and then carries the aerosol generated inside the atomizer core 13 to flow toward the inhaler nozzle 1111. In addition, the support 14 is located at the end of the atomizer core 13 away from the suction nozzle 1111 in the first direction, that is, the support 14 is located below the atomizer core 13 when in use. The support 14 can support the atomizer core 13 and facilitate fixing the atomizer core 13.

[0052] The first communication port 142 of the support 14 is connected to the first mounting hole 121 of the first sealing member 12 to connect with the atomizing core 13. Specifically, Figure 3 In the example, a cylindrical structure can be provided at one end of the support 14 facing the nozzle 1111, and the first communication port 142 is located at the end of the cylindrical structure. The cylindrical structure extends into the first mounting hole 121 of the first sealing member 12 to form a nested connection assembly with the atomizer core 13. The number of the second communication port 143 can be one or more, specifically as follows Figure 7 In the example, a second communication port 143 is provided on opposite sides of the side wall of the support 14. In order to further expand the flow area, the second communication port 143 can be designed as an open hollow structure.

[0053] In addition, in another specific implementation, the air intake pipe 1115 can also be directly connected to the second communication port 143 of the support 14, which can also achieve the air intake effect. The specific design can be based on actual assembly needs.

[0054] Furthermore, if Figure 3 、 Figure 8 and Figure 9As shown, the end of the housing 11 away from the suction nozzle 1111 has a second mounting hole 1121 extending along the first direction. The end of the support 14 away from the suction nozzle 1111 is assembled in the second mounting hole 1121 of the housing 11, and the end of the support 14 away from the suction nozzle 1111 is an assembly end 144, so that the assembly end 144 of the support 14 is exposed through the second mounting hole 1121. The assembly end 144 has an electrode mounting groove 1441 and a process assembly groove 1442, and a through hole 145 is formed inside the support 14, connecting the air guide cavity 141 and the electrode mounting groove 1441. The electrode 15 is mounted in the electrode mounting groove 1441. The conductive portion 1321 of the atomizer core 13 passes through the first connecting port 142 and the air guide cavity 141, and extends from the through hole 145 into the electrode mounting groove 1441, forming an electrical connection with the electrode 15. During use, the electrode 15 can be electrically connected to an external power supply device so as to supply power to the atomizing core 13 through the power supply device to achieve a heating operation.

[0055] The process assembly slot 1442 is used for connection and assembly with an external processing device. During the assembly process of the atomizer 100, the assembly end 144 of the support 14 can be connected to the external processing device and form a positioning match with the external processing device through the process assembly slot 1442. When the conductive portion 1321 of the atomizer core 13 extends from the through hole 145 into the electrode mounting slot 1441, it can contact the corresponding structure on the external processing device and bend under the action of pressure to form an electrical connection with the electrode 15. By providing the process assembly slot 1442, it can cooperate with the external processing device and realize automated bending processing, which is conducive to improving assembly efficiency and operational accuracy.

[0056] It should be noted that the number of electrode mounting slots 1441 can be as follows: Figure 8 The two shown in the figure are used to set two electrodes 15, which correspond to the positive and negative electrodes of the power supply device respectively. Among them, the electrode 15 can be an electrode sheet structure, which can reduce space occupation and increase contact area. In addition, the number of process assembly slots 1442 can be as follows: Figure 8 The two shown in FIG. 1 may also be provided with other numbers of process assembly slots 1442 according to different structures of the external processing device.

[0057] In the embodiment of the second aspect of the present application, an atomization device 200 is provided, such as Figure 1 、 Figure 9 and Figure 10As shown, the atomization device 200 includes a power supply device 21 and the atomizer 100 of any embodiment of the first aspect described above. The atomizer core 13 of the atomizer 100 is electrically connected to the power supply device 21, so that power is supplied to the atomizer core 13 via the power supply device 21, causing the atomizer core 13 to heat, thereby heating and atomizing the matrix liquid and generating an aerosol. The aerosol flows along with the airflow to the mouthpiece 1111 of the atomizer 100 for inhalation by the user.

[0058] Furthermore, the power supply device 21 has a detachable connection structure (such as a snap-fit structure) to be connected and assembled with the atomizer 100 to form an integrated structure for easy operation by the user.

[0059] Of course, in actual applications, the power supply device 21 can also be separated from the atomizer 100 and only electrically connected to the atomizer core 13 through a cable, etc., which can also achieve the effect of supplying power to the atomizer core 13.

[0060] In addition, the atomization device 200 in this embodiment also has all the beneficial effects of the atomizer 100 in any of the above embodiments, which will not be described in detail here.

[0061] A specific embodiment of the atomizer 100 of the present application is described below with reference to the accompanying drawings.

[0062] Please refer to Figures 1 to 9 The atomizer 100 includes a housing 11, a first sealing member 12, and an atomizing core 13. The housing 11 specifically includes a detachably connected outer shell 111 and a base 112. The height direction of the housing 11 is a first direction. In the first direction, one end of the housing 111 has a nozzle 1111, and the other end of the housing 111 is an open structure; the base 112 is connected to the end of the housing 111 away from the nozzle 1111 and is detachably connected to the housing 111 through a snap-fit structure. The portion of the housing 111 near the nozzle 1111 can adopt a double-layer structure to facilitate the molding, processing, and assembly of the nozzle 1111.

[0063] The first sealing member 12 is constructed of a flexible silicone rubber structure and is positioned within the housing 11 near the base 112. The periphery of the first sealing member 12 seals against the inner wall of the housing 11, dividing the interior of the housing 11 into a liquid storage chamber 1113 and an air intake chamber in a first direction. The liquid storage chamber 1113 is located near the mouthpiece 1111, while the air intake chamber is located near the base 112. A first mounting hole 121 is defined in the first sealing member 12, opposite the mouthpiece 1111. The first mounting hole 121 extends through the first direction. One end of the atomizer core 13 extends into the first mounting hole 121 and forms a sealed connection with the first sealing member 12 via a protrusion on the inner wall of the first mounting hole 121. An integrated exhaust duct 1112 is located within the housing 111. One end of the exhaust duct 1112 communicates with the mouthpiece 1111, and the other end communicates with the atomizer core 13.

[0064] A support 14 is provided within the air inlet chamber, with an air guide chamber 141 formed within the support 14. The end of the support 14 facing the nozzle 1111 has a first cylindrical communication port 142 extending into the first mounting hole 121 and connected to the atomizer core 13. A second hollow communication port 143 is provided on the sidewall of the support 14 to connect the air guide chamber 141 with the air inlet chamber. The first sealing member 12 also has an air inlet opening 123 extending in a first direction. The housing 111 also has an independent air inlet duct 1115 formed within it. One end of the air inlet duct 1115 is connected to the air inlet port 1118 on the housing 111, and the other end of the air inlet duct 1115 is sealedly connected to the air inlet opening 123, connecting the air inlet duct 1115 with the air inlet chamber. Among them, an air inlet valve 1119 is provided at the air inlet 1118 of the shell 111, and the air inlet 1118 can be opened or closed by sliding the air inlet valve 1119, so that the air inlet 1118 can be closed when the atomizer 100 is not in use to achieve dust prevention, and at the same time, it can also prevent external airflow from entering and affecting the atomization core 13 and the matrix liquid.

[0065] like Figure 3In the example, the shell 111 also has an independent sensing air channel 161, which is arranged in the air inlet pipe 1115, and one end of the sensing air channel 161 passes through the air inlet opening 123 and extends to the end of the base 112 away from the suction nozzle 1111 to communicate with the outside world, and the other end of the sensing air channel 161 extends to the suction nozzle 1111 of the shell 111 and communicates with the suction nozzle 1111; wherein, an airflow sensor 162 is provided at a position near the suction nozzle 1111 in the sensing air channel 161, and the airflow sensor 162 can be electrically connected to the power supply device or the atomizer core 13, so that when the user performs an inhalation action through the suction nozzle 1111, airflow movement is generated in the sensing air channel 161 under the action of negative pressure, and when the airflow sensor 162 can sense the airflow movement and trigger a corresponding sensing signal, so that the power supply device energizes the atomizer core 13 to perform heating and atomization operation.

[0066] The liquid storage chamber 1113 is used to store the matrix liquid, and the atomizer core 13 is located in the liquid storage chamber 1113. The atomizer core 13 is specifically a cylindrical structure, including an atomizer core sleeve 131, an atomizer core body 132 located in the atomizer core sleeve 131, and a liquid absorption structure 133. A plurality of liquid inlets 1311 are provided on the outer wall of the atomizer core sleeve 131, specifically four liquid inlets 1311 arranged at equal intervals along the circumferential direction, one of the liquid inlet 1311 is opposite to the air inlet pipe 1115, and a liquid blocking structure 122 is provided at the end of the first sealing member 12 facing the suction nozzle 1111 and the positions corresponding to the other three liquid inlets 1311. On the lateral side of the atomizer core sleeve 131, there is a first spacing L between each liquid blocking structure 122 and the corresponding liquid inlet 1311, and each liquid blocking structure 122 blocks the portion of the corresponding liquid inlet 1311 close to the first sealing member 12, so that the liquid inlet 1311 is divided into a blocked area 1312 and an exposed area 1313, wherein the area of the blocked area 1312 accounts for 2 / 3 to 3 / 4 of the total area of the liquid inlet 1311. The side of the liquid retaining structure 122 facing the atomizer core 13 has a curved surface structure 1221, and the curved surface structure 1221 is arranged coaxially with the atomizer core 13. The end of the liquid inlet 1311 near the suction nozzle 1111 has a first curved edge 1314, and correspondingly, the end of the liquid retaining structure 122 facing the suction nozzle 1111 has a second curved edge 1222, and the radius of the second curved edge 1222 is greater than or equal to the radius of the first curved edge 1314. The liquid retaining structure 122 can reduce the liquid flow rate and pressure of the atomizer core 13 in front of the liquid inlet 1311, thereby reducing the possibility of the matrix liquid at the liquid inlet 1311 leaking through the atomizer core 13 without being atomized, thereby improving the problem of matrix liquid leaking through the suction nozzle 1111, which is conducive to improving the user experience, while also improving the atomization efficiency and reducing the waste of matrix liquid.

[0067] A liquid injection port 1116 is provided on the side of the shell 111 opposite to the air inlet 1118 for injecting and withdrawing matrix liquid into and out of the liquid storage chamber 1113; a liquid injection plug 1117 is provided at the liquid injection port 1116 for closing the liquid injection port 1116. When in use, the liquid injection plug 1117 can be pulled out to open the liquid injection port 1116.

[0068] The base 112 defines a second mounting hole 1121, opposite the first mounting hole 121, extending in a first direction. The support 14 is mounted in the second mounting hole 1121 of the base 112 and is sealed therewith. The end of the support 14, distal from the nozzle 1111, is an assembly end 144, exposed through the second mounting hole 1121. The assembly end 144 has two electrode mounting slots 1441 and two process assembly slots 1442. Each electrode mounting slot 1441 houses an electrode sheet. The two conductive portions 1321 of the atomizer core 13 extend through the first connecting port 142, the air guide cavity 141, and the through-hole 145 in the support 14, extending into their corresponding first electrode mounting slots 1441. These portions are bent and electrically connected to the corresponding electrode sheets. The process assembly slots 1442 are designed to connect to an external processing device during assembly to automatically bend the conductive portions 1321, improving assembly efficiency.

[0069] During use, the atomizer 100 can be assembled and connected to a power supply device, so that the electrode sheet of the atomizer 100 is electrically connected to the power supply device, and power is supplied to the atomizer core 13 through the power supply device. When the user takes a puff through the mouthpiece 1111, the airflow sensor 162 senses the airflow movement and generates a corresponding sensing signal. The power supply device is turned on and energized, causing the atomizer core body 132 to heat up, heating the matrix liquid flowing into the atomizer core, atomizing it and generating an aerosol. The intake airflow entering the atomizer core through the intake pipe 1115 carries the aerosol to the mouthpiece 1111 for inhalation by the user.

Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
