[0062] In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application is described in detail below with reference to the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present application.

[0063] The present disclosure provides an atomizer and an electronic atomization device. A nebulizer is a device that atomizes an aerosol-generating substrate into an aerosol. The nebulizer can be used in various atomization scenarios, such as medical cosmetics and daily life. The aerosol-generating substrate to be atomized can be, for example, a cigarette liquid, a medicinal solution, a perfume, or an aerosol substrate that produces a distinctive odor. Those skilled in the art will appreciate that a nebulizer can have a variety of application scenarios, and the present disclosure does not limit such application scenarios.

[0064] 1 and 2 , the electronic atomization device provided in the embodiment of the present disclosure includes an atomizer 100 and a power supply (not shown). The power supply is connected to one end of the atomizer 100 and is electrically connected to the heating element 30 in the atomizer 100. The atomizer 100 has a liquid storage chamber 20 and an atomization chamber 10 connected to the liquid storage chamber 20. The liquid storage chamber 20 is used to store a liquid aerosol-generating matrix. The atomization chamber 10 is provided with a heating element 30 for heating the aerosol-generating matrix. The aerosol-generating matrix stored in the liquid storage chamber 20 flows into the atomization chamber 10 and enters the heating element 30. Under the action of the electrical energy of the power supply, the heating element 30 can heat and atomize the aerosol-generating matrix to generate an aerosol for the user to take.

[0065] However, as described in the background technology, changes in the air pressure inside and outside the liquid storage chamber 20 can cause the electronic atomizer to leak, affecting the user experience. Specifically, during storage, transportation, and use, the electronic atomizer relies on the negative pressure formed in the liquid storage chamber 20 to lock the aerosol-generating matrix, preventing it from leaking. On the other hand, relying on the liquid-locking ability of the heating element 30 itself, even when the negative pressure in the liquid storage chamber 20 is low or even positive, the liquid in the liquid storage chamber 20 will be absorbed by the heating element 30 and will not easily leak out of the liquid storage chamber 20.

[0066] However, as user demand increases, the liquid storage capacity of the liquid storage chamber 20 becomes larger and larger, and as the aerosol generating matrix is ​​continuously consumed, the cavity in the liquid storage chamber 20 becomes larger and larger. When the cavity volume in the liquid storage chamber 20 is too large, the consumption of the aerosol generating matrix is ​​not enough to quickly reduce the pressure in the liquid storage chamber 20 to achieve the liquid storage effect, and it is necessary to rely on the liquid locking ability of the heating element 30 to prevent leakage. However, the heating element 30 can be cylindrical, square, flat, and other shapes, and the materials forming the heating element 30 include organic cotton, ceramics, foam metal, etc. Based on different shapes and materials, the liquid locking ability of different heating elements 30 is also different. Therefore, when the cavity volume in the liquid storage chamber 20 is too large, the heating element 30 with weaker liquid locking ability cannot effectively lock the aerosol generating matrix, resulting in leakage.

[0067] In addition, when the electronic atomization device moves from a low-temperature area to a high-temperature area, such as from a cold night to a warm day, from the outside environment to a car exposed to the sun, from a cool indoor environment to a hot outdoor environment, or from a cold outdoor environment to a warm indoor environment, the pressure in the liquid storage chamber 20 fluctuates with the change in temperature and even rises to a positive pressure, which is also prone to leakage. In particular, when the oil locking ability of the heating element 30 is weak, even a small temperature change can cause oil leakage.

[0068] Based on the above problems, as shown in Figures 1 to 3, an embodiment of the present disclosure provides a nebulizer 100, in which a connected atomizing chamber 10 and a liquid storage chamber 20 are formed inside the nebulizer 100, and the aerosol generating matrix is ​​stored in the liquid storage chamber 20 and converted into an aerosol at the position where the atomizing chamber 10 is located. The nebulizer 100 includes a heating element 30 arranged in the atomizing chamber 10, and the heating element 30 includes a liquid guide 304 and a heating element 305. Among them, the liquid guide 304 itself has the function of guiding and locking liquid. The liquid guide 304 can generally be porous ceramic or oil storage cotton, which can be used to adsorb and store the aerosol generating matrix; the liquid guide 304 can be a hollow component, or it can be a solid component that itself has the function of adsorbing and guiding liquid. The heating element 305 is arranged on the outside of the liquid guiding element 304. The heating element 305 can be a heating wire or a heating film. The heating element 305 can generate heat, and the heat will be transferred to the liquid guiding element 304, causing the liquid guiding element 304 to heat up, thereby causing the aerosol generating matrix at the liquid guiding element 304 to be atomized into an aerosol.

[0069] As shown in FIG3 , the heating element 305 is arranged on the outer surface of the liquid guide 304 to generate heat, that is, the atomizer 100 provided in the embodiment of the present disclosure adopts a heating element 30 with outer membrane heating, which enriches the heating form of the heating element 30. After the heating element 305 is arranged on the outer surface of the liquid guide 304, the volume space of the liquid guide 304 itself is increased, which is conducive to increasing the volume of the aerosol generating matrix stored in the liquid guide 304, increasing the liquid locking ability of the heating element 30, and helping to reduce the possibility of leakage of the atomizer 100. In addition, based on the gas state equation, under the same conditions, temperature and pressure are positively correlated. The atomizer 100 provided in the present disclosure arranges the heating element 305 on the outer surface of the liquid guide member 304, and the heating element 305 is separated from the liquid storage chamber 20. The heating element 305 does not directly contact the aerosol generating matrix in the liquid storage chamber 20, nor does it directly contact the aerosol generating matrix in liquid form in the liquid guide member 304. The liquid guide member 304 can be simply regarded as a heat insulating component between the heating element 305 and the liquid storage chamber 20. The high temperature of the heating element 30 has little effect on the liquid storage chamber 20, which is beneficial to reducing the pressure of the liquid storage chamber 20 in a high temperature environment, thereby reducing the possibility of leakage of the liquid storage chamber 20.

[0070] Example 1 (Figures 1-7):

[0071] As shown in Figures 1 and 2, the first embodiment of the present disclosure provides an atomizer 100. The atomizer 100 is slender and can achieve a miniaturization similar to that of a cigarette. As shown in Figures 3 and 4, the atomizer 100 includes a heating element 30, a base 11, and a top body 12. Figure 4 illustrates the three-dimensional structure of the heating element 30, base 11, and top body 12 after being cut apart. As shown in Figure 5, the heating element 30 includes a liquid guide 304 and a heating element 305.

[0072] As shown in Figures 3 and 4, the base 11 has an air outlet channel 111, and the base 11 is electrically connected to the first electrode 302 set on the outer surface of the liquid guide 304; the top body 12 has an air inlet channel 121, and the top body 12 is electrically connected to the second electrode 303 set on the outer surface of the liquid guide 304; wherein, the heating element 30 is arranged between the air inlet channel 121 and the air outlet channel 111, and the air inlet channel 121 and / or the air outlet channel 111 both extend in the vertical direction, and the extension direction of the liquid guide 304 is perpendicular to the extension direction of the air inlet channel 121 and / or the air outlet channel 111, that is, the heating element is placed horizontally relative to the vertically extended air inlet channel and / or air outlet channel, and the vertical extension direction is also the height direction of the atomizer 100. When the user uses the atomizer 100, the air flow is inhaled from the air inlet channel 121, and drives the aerosol generated by heating and atomization at the heating element 30 to be discharged along the air outlet channel 111 and absorbed by the user. The flow directions of the airflow and the aerosol generating substrate are as shown by the arrows in FIG3 .

[0073] The extension direction of the liquid guide member 304 in the first embodiment of the present disclosure is perpendicular to the extension direction of the air inlet channel 121 and / or the air outlet channel 111, that is, the heating element 30 is placed horizontally relative to the air inlet channel 121 and / or the air outlet channel 111, and the heating element 305 is arranged on the outer surface of the liquid guide member 304 to generate heat. Therefore, the first embodiment of the present disclosure provides a heating element with outer membrane heating used in the atomizer and the heating element is arranged horizontally, which enriches the heating form of the heating element and the horizontal arrangement of the heating element is conducive to the circulation of the aerosol generating matrix to the inside of the heating element.

[0074] In some embodiments, as shown in Figure 5, the liquid guide 304 has a hollow channel 301 for the circulation of the aerosol-generating substrate. The hollow channel 301 penetrates the liquid guide 304, allowing the aerosol-generating substrate to flow into the hollow channel 301, fully contact the inner surface of the liquid guide 304, and be absorbed. The first electrode 302 and the second electrode 303 are respectively disposed at both ends of the heating element 305 and are electrically connected to the heating element 305. When current passes through the heating element 305, the heating element 305 generates heat, which is based on the principle of the electric effect. The heat is transferred to the liquid guide 304, causing it to heat up, which is based on the principle of the thermal effect. In the first embodiment of the present disclosure, the liquid guide 304 has a hollow channel 301 for the circulation of the aerosol-generating substrate. The aerosol-generating substrate enters the hollow channel 301 and fully contacts the liquid guide 304, allowing the liquid guide 304 to fully absorb and store the aerosol-generating substrate, ensuring timely liquid supply.

[0075] In some embodiments, as shown in Figures 4 and 6, the cavity inside the base 11 forms an atomization chamber 10. The base 11 is provided with a first groove 112 on both sides of the air outlet channel 111 for placing the heating element 30. The air outlet channel 111 extends vertically and passes through the base 11. The first groove 112 passes through the base 11 laterally, so that when the heating element 30 is placed in the first groove 112 and is limited, the aerosol generation matrix can also be input through the liquid guide 304; a first boss 113 electrically connected to the first electrode 302 of the heating element 30 is provided in the first groove 112 on one side of the air outlet channel 111, and the first boss 113 protrudes from the surface of the first groove 112. The base in the first embodiment of the present disclosure is provided with a first groove on both sides of the air outlet channel for placing the heating element, so that the heating element can be placed in the first groove and be limited; a first boss electrically connected to the first electrode of the heating element is provided in the first groove on one side of the air outlet channel, so that the first electrode of the heating element is electrically connected to the base.

[0076] In some embodiments, as shown in FIG7 , the top body 12 includes a main body 122 and a second boss 123. The main body 122 is provided with an air inlet channel 121 passing through the main body 122; the second boss 123 protrudes from the top surface of the main body 122 and is located at one end close to the heating element 30; the second boss 123 is electrically connected to the second electrode 303 of the heating element 30. The top body in the first embodiment of the present disclosure includes a main body and a second boss, and the main body is provided with an air inlet channel passing through the main body, so that the air flow can enter the heating element 305 from the outside of the main body along the air inlet channel, and drive the aerosol generated by heating and atomization at the heating element 305 to be discharged along the air outlet channel; the second boss is electrically connected to the second electrode of the heating element, so that the second electrode of the heating element is electrically connected to the top body. The top body 12 and the base 11 are both conductive components, and the materials used in their manufacture are all materials that are easy to conduct electricity.

[0077] In some embodiments, as shown in Figures 3 and 4, the first boss 113 and the second boss 123 are both in contact with the outer surface of the heating element 30, and the heating element 30 is cylindrical in shape. The surfaces of the first boss 113 and the second boss 123 are both inwardly concave arc surfaces, so that the heating element 30 can be just pressed; and the heating part of the heating element 30 is located between the first boss 113 and the second boss 123, that is, the heating element 305 of the heating element 30 is located between the first boss 113 and the second boss 123, and the heating part of the heating element 30 is roughly in the extension direction of the air inlet channel 121 and the air outlet channel 111, so that the airflow can easily drive the aerosol generated at the heating element 30 to flow out. The first boss and the second boss in the first embodiment of the present disclosure are both in contact with the outer surface of the heating element, so that the first boss and the second boss are respectively electrically connected to the first electrode and the second electrode set on the outer surface of the heating element, and at the same time, the first boss and the second boss play a certain limiting role on the heating element.

[0078] In some embodiments, as shown in Figures 3 and 4, the atomizer 100 further includes a first insulating member 13. For example, the material of the first insulating member 13 can be plastic or other insulating materials. The first insulating member 13 extends into the base 11 from the side of the base 11 opposite to the air outlet channel 111. The first insulating member 13 is sleeved outside the top body 12 to separate the base 11 from the top body 12. The atomizer provided in the first embodiment of the present disclosure further includes a first insulating member. The first insulating member is sleeved outside the top body to separate the base and the top body, thereby separating the base and the top body. Instead of being directly electrically connected, they are respectively connected to the positive and negative ends of the power supply to form a closed loop. After being powered on and used, it is not easy to cause a short circuit, thereby reducing safety risks.

[0079] In some embodiments, as shown in FIG3 , the outer surface of the first insulating member 13 is provided with threads, so that the first insulating member 13 can be detachably connected to the power supply, so that the user can remove it to replace the power supply; the power supply is electrically connected to the base 11 and the top body 12, and the positive and negative poles of the power supply are respectively connected to the base 11 and the top body 12, thereby electrically connected to the first boss 113 and the second boss 123 to form a closed loop. When the power is turned on and the current passes through the heating element 305, the heating element 305 will generate heat. This is based on the principle of the electrical effect. When the power is turned off, the heating element 30 is not powered and the atomizer 100 does not work. Heat will be transferred to the liquid guide member 304, causing it to heat up. This is based on the principle of the thermal effect. The first insulating member in the first embodiment of the present disclosure is connected to the power supply. After the connection, the power supply is electrically connected to the base and the top body, so that the power supply is electrically connected to the first electrode and the second electrode, so that the heating element can be electrically conductive to generate aerosol by atomizing the aerosol to generate a matrix as an aerosol.

[0080] In some embodiments, as shown in Figures 2 and 3, the atomizer 100 provided in the first embodiment of the present disclosure further includes a housing 14, which is sleeved on the outside of the base 11, and the interior of the housing 14 has a liquid storage chamber 20 for accommodating an aerosol-generating matrix; wherein, both ends of the heating element 30 are connected to the liquid storage chamber 20 to input the aerosol-generating matrix. The atomizer provided in the first embodiment of the present disclosure further includes a housing 14, which has a liquid storage chamber 20 for accommodating an aerosol-generating matrix, and both ends of the heating element 30 are connected to the liquid storage chamber 20 to input the aerosol-generating matrix, so that the liquid guide 304 can adsorb and store the aerosol-generating matrix entering the hollow flow channel 301, and the heating element 305 generates heat, which is transferred to the liquid guide 304 to heat it up, thereby heating it to atomize the aerosol-generating matrix and generate an aerosol.

[0081] In some embodiments, as shown in FIG3 , the atomizer 100 further includes a first sealing member 15 . For example, the first sealing member 15 can be made of materials such as silicone. The first sealing member 15 is sleeved on both ends of the extension direction of the heating element 30 . The first sealing member 15 is respectively arranged adjacent to the first boss 113 and the second boss 123 . After the first sealing member 15 is tightened, the heating element 30 can be stably centered in the base 11 and is not easy to move laterally. The heating portion (heating element 305) of the heating element 30 is stably located between the first boss 113 and the second boss 123 , that is, roughly in the extension direction of the air inlet channel 121 and the air outlet channel 111 . Thus, the airflow can easily drive the aerosol generated at the heating element 30 to flow out; the first sealing member 15 is located on the lateral outside of the first electrode 302 and the second electrode 303 to seal the liquid storage chamber 20. Part of the surface of the first sealing member 15 abuts against the heating element 30 and the base 11 for sealing, and part of the surface abuts against the heating element 30 and the first insulating member 13 for sealing, so that the aerosol generating matrix is ​​not easy to leak from the gap between the heating element 30 and other structures into the air inlet channel 121 and / or the air outlet channel 111, and mix with the aerosol generated by heating and atomization of the heating element 30, affecting the quality and taste of the aerosol absorbed by the user.

[0082] The atomizer provided in the first embodiment of the present disclosure further includes a first seal 15, which is located on the transverse outer side of the first electrode 302 and the second electrode 303 to seal the liquid storage chamber 20, so that the aerosol-generating matrix is ​​not easily leaked from the gap between the heating element 30 and other structures into the air inlet channel 121 and / or the air outlet channel 111, and mixed with the aerosol generated by heating and atomization of the heating element 30, thereby affecting the quality and taste of the aerosol absorbed by the user.

[0083] In some embodiments, as shown in FIG3 , the first sealing member 15 can be made of a material such as cotton to absorb the aerosol-generating substrate and direct it to the liquid-conducting member 304 , thereby heating and atomizing the aerosol-generating substrate to generate an aerosol. The first sealing member in the first embodiment of the present disclosure can absorb the aerosol-generating substrate and direct it to the liquid-conducting member 304 , thereby heating and atomizing the aerosol-generating substrate to generate an aerosol.

[0084] Example 2 (Figures 8-16):

[0085] As shown in Figures 8 and 11 , the second embodiment of the present disclosure provides an atomizer 100 . The atomizer 100 is slender and can be miniaturized to resemble a cigarette. The atomizer 100 includes a heating element 30 and a ventilation tube 21 . 9, 10, 12 and 13, the heating element 30 extends along a first direction, the first direction being the Z direction shown in FIG10 and 13, and the heating element 30 includes a liquid guide 304 and a heating element 305, the heating element 305 being located outside the liquid guide 304, so that the outer surface of the heating element 30 generates heat to atomize the aerosol and atomize the aerosol matrix into an aerosol; the heating element 30 is disposed in the vent tube 21, and the air flow channel 22 for air flow passes through the vent tube 21, so it can be understood that the internal cavity of the vent tube 21 forms the atomization chamber 10; wherein, at least a portion of the air flow channel 22 extends along the first direction, and it can be understood that even if the air flow channel 22 has a portion that does not extend along the first direction, it extends along the first direction as a whole, and the air flow channel 22 is located outside the outer surface of the liquid guide 304, and the aerosol generated by the heat atomization diffuses to the outside of the outer surface of the heating element 30, and when the user inhales, the air flow drives the aerosol from the air flow channel 22 to the user's mouth to be absorbed by the user.

[0086] The liquid guide member 304 in the second embodiment of the present disclosure extends along the extension direction of the air flow channel 22, that is, the heating element 30 is placed longitudinally relative to the air flow channel 22, and the outer surface of the heating element 30 generates heat. Therefore, the second embodiment of the present disclosure provides a heating element with outer membrane heating used in the atomizer and the heating element is arranged longitudinally, which enriches the heating form of the heating element and the longitudinal arrangement of the heating element is conducive to the miniaturization of the overall width of the atomizer.

[0087] In some embodiments, as shown in Figures 10, 13 and 14, Figures 10 and 14 illustrate the images obtained after the atomizer is cut along the same direction, but the angles shown are different; Figures 10 and 13 illustrate cross-sectional views obtained after the atomizer 100 is cut from two mutually perpendicular directions. The atomizer 100 also includes a second seal 23. The specific structure of the second seal 23 is shown in Figure 15. The second seal 23 is located in the vent tube 21. The second seal 23 extends along the first direction and is sleeved on the outside of the liquid guide member 304 of the heating element 30, so that the second seal 23 can seal the gap between the vent tube 21 and the liquid guide member 304, reducing the possibility that the aerosol atomized matrix penetrates into the air flow channel 22 through the gap and mixes with the aerosol generated by heating and atomization by the heating element 305, affecting the quality and taste of the aerosol absorbed by the user. For example, the second seal 23 can be made of materials such as silicone. The second sealing member 23 is provided with a liquid through hole 231 extending along a second direction to transmit the aerosolized matrix to the liquid guide member 304. The second direction is a direction composed of the X direction and the Y direction as shown in Figures 10 and 13. The second direction is perpendicular to the first direction, and the second direction can be simply understood as a horizontal direction; wherein, the air flow channel 22 passes through the outside of the second sealing member 23. It can be understood that the air flow channel 22 is located between the outside of the second sealing member 23 and the inside of the ventilation tube 21.

[0088] The atomizer provided in the second embodiment of the present disclosure also includes a second sealing member 23, which is located in the ventilation tube 21. The second sealing member 23 extends along the first direction and is sleeved on the outside of the heating element 30, so that the second sealing member 23 can seal the gap between the ventilation tube 21 and the heating element 30, thereby reducing the possibility that the aerosol atomized matrix can penetrate into the air flow channel 22 through the gap and mix with the aerosol generated by heating and atomization by the heating element 305, thereby affecting the quality and taste of the aerosol absorbed by the user.

[0089] In some embodiments, as shown in Figures 13 and 15, the outer surface of the second sealing member 23 is provided with a second groove 232 extending along the first direction, and the air flow channel 22 passes through the second groove 232. The second groove 232 is separated from the liquid through hole 231. It can be understood that the second groove 232 and the liquid through hole 231 are not connected in a columnar manner. The aerosol atomization matrix at the liquid through hole 231 can be adsorbed and heated and atomized by the heating element 30, and the generated aerosol is discharged into the air flow channel 22 adjacent to the heating part (heating element 305) of the heating element 30, and then further discharged through the second groove 232. That is, the aerosol atomization matrix at the liquid through hole 231 is not directly connected to the aerosol flowing through the second groove 232.

[0090] The outer surface of the second seal of the second embodiment of the present disclosure is provided with a second groove extending along the first direction, and the air flow channel passes through the second groove. The second groove is separated from the liquid through hole, that is, the second groove is not connected to the liquid through hole. The aerosol atomization matrix at the liquid through hole can be adsorbed and heated and atomized by the heating element, and the generated aerosol is discharged into the air flow channel adjacent to the heating part of the heating element (heating element 305), and then further discharged through the second groove, thereby realizing the separation of the aerosol and the aerosol atomization matrix, and largely avoiding the leakage of the aerosol atomization matrix into the air flow channel, affecting the quality and taste of the aerosol absorbed by the user.

[0091] In some embodiments, as shown in FIG16 , the heating element 30 includes a liquid guide 304, a heating element 305, and two electrode elements. The two electrode elements are respectively disposed on the outer surface of the liquid guide 304 and connected to the ends of the heating element 305 to be electrically connected to the heating element 305. When current passes through the heating element 305, the heating element 305 generates heat, which is based on the principle of the electric effect. The heat is transferred to the liquid guide 304, causing it to heat up, which is based on the principle of the thermal effect.

[0092] In some embodiments, as shown in Figures 10, 13 and 14, the liquid guide member 304 has a cavity 306 extending along the first direction and open at one end, and the open end of the cavity 306 is closed by other components, so that when the aerosol atomized matrix is ​​adsorbed by the side wall of the liquid guide member 304, it can be absorbed into the cavity 306 and stored in the cavity 306, so as to ensure the timeliness of the supply of the aerosol atomized matrix during atomization, and the aerosol atomized matrix stored in the cavity 306 is not easy to leak from both ends of the cavity 306; the two electrode members include a first electrode 302 and a second electrode 303, the first electrode 302 is arranged at one end of the closed cavity 306 of the liquid guide member 304, and the closed end is located away from the air flow channel 22 One end of the outlet; the second electrode 303 is arranged at the open end of the cavity 306; wherein the heating element 305 is arranged near the closed end of the cavity 306, and the closed end is located at the end away from the outlet of the air flow channel 22. Therefore, when the user uses the atomizer 100 in a normal state, the normal state refers to that the outlet end of the atomizer 100 is above the inlet end, so that the open end of the cavity 306 is above the closed end of the cavity 306, so that the aerosol atomization matrix in the cavity 306 will flow to the position of the liquid guide 304 near the closed end of the cavity 306 under the action of gravity, that is, close to the heating element 305, so that the aerosol atomization matrix in the cavity 306 can easily absorb the heat generated by the heating element 305 and atomize.

[0093] The liquid guiding member 304 provided in the second embodiment of the present disclosure has a cavity 306 extending along the first direction therein, so that when the aerosol atomization matrix is ​​adsorbed by the liquid guiding member 304, it can be stored in the cavity 306, so as to ensure the timeliness of the supply of the aerosol atomization matrix during atomization; the heating member 305 is arranged near the end of the liquid guiding member 304 away from the outlet of the air flow channel 22. Therefore, when the user uses the atomizer in a normal state, the aerosol atomization matrix will flow to the position of the closed end of the liquid guiding member 304 near the cavity 306 under the action of gravity, that is, near the heating member 305, so that the aerosol generating matrix in the cavity 306 can easily absorb the heat generated by the heating member 305 and atomize.

[0094] In some embodiments, as shown in Figures 10, 13, and 14, the atomizer 100 further includes a conductive ejector pin 24 and a conductive sheet 25. The conductive ejector pin 24 is partially inserted into the vent tube 21 and abuts against the closed end of the heating element 30, that is, the end away from the outlet of the air flow channel 22. The conductive ejector pin 24 is electrically connected to the first electrode 302. The conductive sheet 25 is located in the vent tube 21 and abuts against the open end of the heating element 30, and is electrically connected to the second electrode 303. The air flow channel 22 passes through the conductive sheet 25, so that the air flow can pass through the conductive sheet 25 and flow out. A gasket is abutted between the conductive sheet 25 and the open end of the heating element 30, so that the gap between the conductive sheet 25 and the heating element 30 can be better sealed, reducing the possibility of the aerosol atomized matrix leaking out of the cavity 306 and leaking into the outside of the atomizer 100 or the internal gap of the atomizer 100. The atomizer provided in the second embodiment of the present disclosure also includes a conductive pin and a conductive sheet. The conductive pin abuts against the closed end of the heating element and is electrically connected to the first electrode. The conductive sheet abuts against the open end of the heating element and is electrically connected to the second electrode. The conductive pin and the conductive sheet are both conductive components, and the materials used in their manufacture are all materials that are easy to conduct electricity. The provision of the conductive pin and the conductive sheet facilitates the electrical connection between the first electrode and the second electrode, and also facilitates a certain limiting effect on the heating element.

[0095] In some embodiments, as shown in Figures 10, 13 and 14, the conductive ejector pin 24 has a hollow channel 241 extending along the first direction. The hollow channel 241 is open at one end away from the heating element 30 in the first direction so that the intake air flow enters the hollow channel 241 from the opening; the conductive ejector pin 24 has a through hole 242 connected to the hollow channel 241, and the through hole 242 is located in the vent pipe 21 to connect to the air flow channel 22. It can be understood that the conductive sheet 25 is located in the vent pipe 21, and the through hole 242 is opened on the side wall of the vent pipe 21, so that the through hole 242 is located in the vent pipe 21. After the air flow enters the hollow channel 241 from the opening, it can enter the air flow channel 22 from the through hole 242. The conductive ejector pin in the second embodiment of the present disclosure has a hollow channel extending along the first direction. One end of the hollow channel is open, and the air flow enters the hollow channel from the opening. The conductive ejector pin is provided with a through hole connected to the hollow channel. The through hole is located in the ventilation tube to connect the air flow channel. After the air flow enters the hollow channel from the opening, it can enter the air flow channel from the through hole and drive the aerosol in the air flow channel to flow out for absorption by the user.

[0096] In some embodiments, as shown in Figures 10, 13 and 14, the atomizer 100 further includes a conductive connector 26, which surrounds the outside of the conductive ejector pin 24 and is sleeved on the vent tube 21. The conductive connector 26 is electrically connected to the conductive sheet 25. It can be understood that the conductive connector 26 is indirectly electrically connected to the conductive sheet 25. The conductive connector 26 is sleeved on the vent tube 21 and is electrically connected. The conductive sheet 25 is located in the vent tube 21 and contacts and is electrically connected to the vent tube 21. The vent tube 21, the conductive connector 26 and the conductive sheet 25 are all conductive components, and the materials used in their manufacturing are all materials that are easy to conduct electricity. Among them, the conductive connector 26 and the conductive ejector pin 24 are electrically connected to the positive and negative poles of the power supply respectively. For example, the positive pole of the power supply is connected to the conductive connector 26, the vent tube 21, the conductive sheet 25, and the second electrode 303, and the negative pole of the power supply is connected to the conductive ejector pin 24 and the first electrode 302, thereby electrically connecting to the first electrode 302 and the second electrode 303 to form a closed loop. When the power is turned on and the current passes through the heating element 305, the heating element 305 will generate heat. This is based on the principle of electrical effect. When the power is turned off, the heating element 30 is not powered and the atomizer 100 does not work. Heat will be transferred to the liquid guide member 304 to heat it up. This is based on the principle of thermal effect. The atomizer provided in the second embodiment of the present disclosure also includes a conductive connector. The conductive connector and the conductive ejector pin are electrically connected to the positive and negative poles of the power supply respectively, thereby electrically connecting to the first electrode and the second electrode to form a closed loop, so that the heating element can be powered and heat-conducted to atomize the aerosol and atomize the matrix as an aerosol.

[0097] In some embodiments, as shown in Figures 10, 13, and 14, the atomizer 100 further includes a second insulating member 27. For example, the material of the second insulating member 27 can be plastic or other insulating materials. The second insulating member 27 is disposed between the conductive ejector pin 24 and the conductive connector 26 to separate the conductive ejector pin 24 from the conductive connector 26. The atomizer provided in the second embodiment of the present disclosure further includes a second insulating member, which is disposed between the conductive ejector pin and the conductive connector to separate the conductive ejector pin and the conductive connector. This separates the conductive ejector pin and the conductive connector, and prevents direct electrical connection. Instead, the conductive ejector pin and the conductive connector are respectively connected to the positive and negative terminals of the power supply to form a closed circuit. This makes it less likely to cause a short circuit after power is applied, thereby reducing safety risks.

[0098] In some embodiments, as shown in Figure 10, the nebulizer 100 also includes a shell 14, which is mounted on the outside of the ventilation tube 21, and a liquid storage chamber 20 for accommodating an aerosol atomized matrix is ​​formed between the shell 14 and the ventilation tube 21; wherein the ventilation tube 21 has a first lower liquid hole 211 connecting the liquid storage chamber 20 and the liquid through hole 231 of the second sealing member 23, so that the aerosol atomized matrix passes from the liquid storage chamber 20 through the first lower liquid hole 211 to the liquid through hole 231, and is then adsorbed and stored by the liquid guide member 304 of the heating element 30. The atomizer of the disclosed embodiment also includes a shell, a liquid storage chamber for accommodating an aerosol atomization matrix is ​​formed between the shell and the ventilation tube, and the ventilation tube has a first lower liquid hole connected to the liquid storage chamber and the liquid through hole of the second sealing member, so that the aerosol atomization matrix passes through the first lower liquid hole from the liquid storage chamber to the liquid through hole, and is then adsorbed and stored by the liquid guide member of the heating element. The heating element generates heat, and the heat is transferred to the liquid guide member to heat it up, thereby heating it to atomize the aerosol atomization matrix and generate an aerosol.

[0099] Example 3 (Figures 17 to 25):

[0100] As shown in FIG. 17 to FIG. 25 , the atomizer 100 provided in the third embodiment has a structure that is the same as or similar to that of the first embodiment.

[0101] Specifically, referring to Figure 18 , the liquid-guiding member 304 provided in the third embodiment extends perpendicularly to the direction of extension of the airway (central airway 341), and / or the liquid-guiding member 304 includes a hollow channel 301 therein, through which the aerosol-generating substrate circulates. Specifically, the liquid-guiding member 304 is positioned transversely relative to the airway (central airway 341), and / or the aerosol-generating substrate can flow into the inner surface of the liquid-guiding member 304 at both ends of the hollow channel 301. This arrangement facilitates the flow of the aerosol-generating substrate into the liquid-guiding member 304, allowing it to fully contact and be absorbed by the inner surface of the liquid-guiding member 304. This facilitates enhancing the liquid-locking capacity of the liquid-guiding member 304 and rapidly absorbing any leaked liquid expelled from the liquid storage chamber 20.

[0102] Of course, this only illustrates one possible way to implement it. In some possible implementation schemes, Example 3 may also have a structure that is the same or similar to Example 2. Specifically, the extension direction of the liquid guide 304 provided in Example 3 may be the same as the extension direction of the airway (central airway 341), and / or, the interior of the liquid guide 304 has a cavity 306 extending in a first direction and open at one end, and the open end of the cavity 306 is closed by other components. That is, the liquid guide 304 is placed longitudinally relative to the airway (central airway 341), and / or, the aerosol generating matrix is ​​absorbed from the side wall of the liquid guide 304 into the cavity 306. This arrangement is conducive to the miniaturization of the overall width of the atomizer, and can make full use of the height space of the atomizer 100 to set the longitudinally extending heating element 30, so as to increase the volume and liquid locking capacity of the liquid guide 304, and expand the space in which the liquid guide 304 can absorb the aerosol generating matrix squeezed out of the liquid storage chamber 20.

[0103] 18 , the atomizer 100 provided in the third embodiment includes a main housing 31 , an atomization module 32 , an upper cover module 33 and a central tube 34 .

[0104] Referring to Figure 17 , the main housing 31 is a hollow, cubical structure with two open ends, including a first open end and a second open end positioned opposite each other. A lower liquid portion 311 is integrally formed within the main housing 31. This lower liquid portion 311 is positioned between the first and second open ends and defines a second lower liquid hole 312 that connects the first and second open ends. It should be understood that the shape of the main housing 31 is not limited to this and can be customized to meet different requirements.

[0105] In the following embodiments, the height direction of the main shell 31 is defined as the first direction (i.e., the Z direction in Figure 18), the length direction of the main shell 31 is defined as the second direction (i.e., the X direction in Figure 18), the width direction of the main shell 31 is defined as the third direction (i.e., the Y direction in Figure 18), the first opening end and the second opening end are arranged opposite to each other in the first direction, and the second lower liquid hole 312 opened on the lower liquid part 311 extends along the first direction to penetrate the lower liquid part 311.

[0106] The atomizer module 32 is mounted on the first open end of the main housing 31 and is located on one side of the lower liquid portion 311. It includes a mounting base 321 and a heating element 30. The mounting base 321 includes a base top wall and a base side wall extending from the edge of the base top wall in a first direction away from the lower liquid portion 311. The base top wall, the lower liquid portion 311, and the side wall of the main housing 31 collectively define the atomizer chamber 10.

[0107] A limiting portion 3211 for limiting the position of the heating element 30 is protruding from the top wall of the base. The heating element 30 has a hollow cylindrical structure. The heating element 30 is clamped in the limiting portion 3211 and installed on the top of the side of the mounting seat 321 facing the lower liquid portion 311, and the central axis of the heating element 30 extends along the second direction, that is, the heating element 30 is placed horizontally.

[0108] The upper cover module 33 is mounted on the second open end of the main housing 31 to close the second open end. The upper cover module 33 , the lower liquid portion 311 and the main housing 31 together form the liquid storage chamber 20 .

[0109] One end of the central tube 34 is inserted into the upper cover module 33 and communicates with the external atmosphere. The other end of the central tube 34 extends along the first direction until it is inserted into the lower liquid portion 311. The liquid storage chamber 20 circumferentially surrounds the outside of the central tube 34. A central airway 341 is formed in the central tube 34 to connect the atomization chamber 10 and the external atmosphere. The aerosol generated in the atomization chamber 10 can flow out of the atomization device through the central airway 341.

[0110] 19 , 22 and 23 , the atomizer 100 provided in the third embodiment of the present disclosure is further provided with at least one ventilation groove connected to the atomizing chamber 10 , and the aerosol-generating matrix in the liquid storage chamber 20 can enter the ventilation groove through the atomizing chamber 10 under the action of the air pressure in the liquid storage chamber 20 .

[0111] In this way, when the air pressure in the liquid storage chamber 20 increases, the aerosol-generating matrix squeezed out of the liquid storage chamber 20 can be stored in the ventilation groove, thereby reducing the pressure in the liquid storage chamber 20 and achieving internal and external balance. When the air pressure in the liquid storage chamber 20 decreases with the temperature or the consumption of the aerosol-generating matrix decreases, the external atmospheric pressure will push the aerosol-generating matrix in the ventilation groove back into the liquid storage chamber 20 until it is absorbed by the liquid guide 304 of the heating element 30. It can be seen that the provision of the ventilation groove can eliminate or reduce the leakage of the atomization device, reduce the requirements for the liquid locking ability of the heating element 30, and facilitate the further expansion of the volume of the liquid storage chamber 20, thereby improving the user experience of the electronic atomization device.

[0112] In some embodiments, the cross-sectional area of ​​the ventilation groove is 0.1 mm²-2 mm², which provides less flow resistance than the heating element 30. Therefore, when the air pressure in the liquid storage chamber 20 increases, most of the aerosol-generating substrate extruded from the liquid storage chamber 20 enters the ventilation groove for storage, significantly reducing the liquid storage requirements of the heating element 30. The cross-sectional area refers to the cross-sectional area perpendicular to the flow direction of the aerosol-generating substrate when it flows through the ventilation groove.

[0113] As shown in Figures 19 to 21, in some embodiments, the mounting seat 321 is provided with a first ventilation groove 322, and the first ventilation groove 322 is connected to the bottom wall of the atomization chamber 10 (i.e., the top wall of the base of the mounting seat 321), so that the aerosol generating matrix in the atomization chamber 10 can flow smoothly into the first ventilation groove 322 under the action of gravity.

[0114] Because the longer the ventilation groove is, the more space it can store for aerosol-generating substrate, the greater the liquid storage capacity, and the greater its ability to withstand greater pressure changes, in a preferred embodiment, one end of the first ventilation groove 322 is located on one side of the mounting seat 321 in the third direction and extends from the base top wall to the base side wall, while the other end of the first ventilation groove 322 extends circumferentially around the mounting seat 321 to the other side of the mounting seat 321 in the third direction and extends to the base top wall. It will be understood that the shape of the first ventilation groove 322 is not limited to that shown in the schematic diagrams of Figures 19-21 and can be configured as needed to meet different liquid storage requirements.

[0115] As shown in conjunction with Figures 18 and 22 , in some embodiments, a second ventilation groove 342 is defined in the outer wall of the central tube 34 near the axial end of the atomization chamber 10. Because a longer ventilation groove provides more space for storing aerosol-forming substrate, greater liquid storage capacity, and greater resistance to greater pressure changes, as a preferred embodiment, the second ventilation groove 342 extends spirally around the central axis of the central tube 34. It will be appreciated that the shape of the second ventilation groove 342 is not limited to that illustrated in Figure 22 and can be configured as needed to meet different liquid storage requirements.

[0116] As shown in conjunction with Figures 18 and 23 , in some embodiments, the lower liquid portion 311 of the main housing 31 forms a pressing surface 313 on one side of the main housing 31 that contacts and presses the heating element 30. The pressing surface 313 defines a zigzag extending third ventilation groove 3131. It will be appreciated that the shape of the third ventilation groove 3131 is not limited to that shown in Figure 23 and can be configured as needed to meet different liquid storage requirements.

[0117] In some embodiments, the atomizer 100 is provided with a first ventilation groove 322, a second ventilation groove 342 and a third ventilation groove 3131. In other embodiments, the atomizer 100 may only be provided with one or two of the first ventilation groove 322, the second ventilation groove 342 and the third ventilation groove 3131.

[0118] It should be noted that the location of the ventilation groove is not limited to the arrangement illustrated in Figures 18-23. In particular, for high-viscosity aerosol-generating substrates, the ventilation groove should be located in an area where the temperature rises more rapidly during use. Higher temperatures can reduce the viscosity of the aerosol-generating substrate, thereby facilitating the reciprocating flow of the aerosol-generating substrate within the ventilation groove. In the above embodiment, the central tube 34, the side of the mounting seat 321 near the heating element 30, and the pressing surface 313 of the lower liquid portion 311 are all located in relatively high-temperature areas, thereby achieving a good liquid storage effect. The pressing surface 313 of the lower liquid portion 311 is in direct contact with the heating element 30 and thus has a relatively high temperature. Simultaneously, the aerosol-generating substrate within the third ventilation groove 3131 located on the pressing surface 313 can directly contact the heating element 30. Therefore, the aerosol-generating substrate within the third ventilation groove 3131 can be directly absorbed and consumed by the heating element 30, thereby achieving a better leakage prevention effect.

[0119] During the research process, the applicant further discovered that when the high-temperature aerosol generated by the atomization of the aerosol-generating matrix flushes the central tube 34, the temperature of the central tube 34 rises and transfers heat to the air in the liquid storage chamber 20. According to the thermal expansion and contraction effect, the pressure in the liquid storage chamber 20 is easily affected by the temperature of the central tube 34 and increases, thereby posing the possibility of leakage.

[0120] To address the above issues, as shown in Figure 24 , in some embodiments, the outer wall of the central tube 34 is covered with a thermal insulation layer 35. Specifically, in one embodiment, the atomizer 100 includes an insulating tube formed from an insulating material such as silicone, which is sleeved over the outer surface of the central tube 34 to form the thermal insulation layer 35. In other embodiments, the outer wall of the central tube 34 can be surface-treated to form a coating to serve as the thermal insulation layer 35.

[0121] In this way, the thermal insulation layer 35 can prevent the heat of the central tube 34 from being transferred to the liquid storage chamber 20 to a certain extent, thereby reducing the possibility of the air pressure in the liquid storage chamber 20 increasing due to excessive temperature, and further reducing the leakage phenomenon.

[0122] In some embodiments, at least a portion of the wall of the liquid storage chamber 20 can undergo recoverable deformation under the action of air pressure to change the volume of the liquid storage chamber 20. Thus, when the air pressure within the liquid storage chamber 20 increases due to a temperature rise, a portion of the wall of the liquid storage chamber 20 expands, increasing the volume of the liquid storage chamber 20 and suppressing further increases in air pressure, thereby preventing or reducing leakage.

[0123] As shown in FIG25 , in one embodiment, the atomizer 100 includes an elastic membrane 36 , which is a thin film formed of an elastic material such as silicone. The elastic membrane 36 is mounted on the second open end of the main housing 31 and is located on the side of the upper cover assembly facing the atomization module 32 . The main housing 31 and the elastic membrane 36 together define the liquid storage chamber 20 . The elastic membrane 36 can undergo recoverable deformation under the action of air pressure to change the volume of the liquid storage chamber 20 . It will be understood that the parameters such as the material, installation position, and area of ​​the elastic membrane 36 are not limited and can be set as needed. The greater the deformation of the wall of the liquid storage chamber 20, the greater the temperature difference it can withstand.

[0124] The atomizer 100 and electronic atomization device of the third embodiment, by providing a ventilation groove to accommodate the aerosol-generating substrate, eliminates or reduces leakage from the atomization device when air pressure changes, thereby lowering the requirements for the liquid-locking capacity of the heating element 30. Furthermore, the provision of the thermal insulation layer 35 effectively reduces the possibility of pressure increases within the liquid storage chamber 20 due to excessive temperature in the central tube 34. Furthermore, the provision of the elastic membrane 36 regulates the volume of the liquid storage chamber 20, further reducing leakage.

[0125] Example 4 (Figures 17, 18, 26-29):

[0126] It should be noted that the atomizer 100 provided in the fourth embodiment has a structure identical or similar to that of the third embodiment. The identical or similar aspects between the fourth embodiment and the third embodiment can be referred to each other and will not be described in detail here for the sake of brevity.

[0127] Compared with the third embodiment, the fourth embodiment is different in that:

[0128] The liquid storage chamber 20 of the atomizer 100 provided in the fourth embodiment includes at least two sub-chambers 41 , each sub-chamber 41 is connected to another sub-chamber 41 or the atomizing chamber 10 , and there is at least one sub-chamber 41 connected to the atomizing chamber 10 .

[0129] In this way, by dividing a larger liquid storage chamber 20 into multiple smaller sub-chambers 41, the formation of an excessively large cavity due to the consumption of the aerosol-generating matrix during the suction process can be avoided, thereby preventing the establishment of negative pressure in the liquid storage chamber 20, and effectively locking the aerosol-generating matrix in the liquid storage chamber 20, eliminating or reducing the leakage phenomenon of the electronic atomization device.

[0130] 26 and 27 , the atomizer 100 provided in the fourth embodiment of the present disclosure further includes at least one first partition 42, all of which are located in the liquid storage chamber 20, and each first partition 42 forms a sub-chamber 41 on opposite sides in the first direction, and each first partition 42 opens a third lower liquid hole 422 that connects two adjacent sub-chambers 41. It can be understood that the number of first partitions 42 is not limited, as long as the first partition 42 can divide the liquid storage chamber 20 into at least two sub-chambers 41. Along the first direction from the end away from the heating element 30 to the end close to the heating element 30, that is, along the direction from top to bottom, all sub-chambers 41 are arranged in sequence and connected in sequence, and the sub-chamber 41 closest to the heating element 30 (which can be the second sub-chamber 412 in FIG. 26 ) is connected to the atomization chamber 10. As a preferred embodiment, the volume of the sub-cavity 41 decreases successively from the end away from the heating element 30 to the end close to the heating element 30 along the first direction, that is, the volume of the sub-cavity 41 decreases along the direction from top to bottom.

[0131] In this way, the aerosol-generating substrate in the sub-cavity 41 farther from the heating element 30 flows through the third lower liquid hole 422 into the adjacent sub-cavity 41 closer to the heating element 30. Because the third lower liquid hole 422 creates a certain resistance to the flow of the aerosol-generating substrate, the consumption of the aerosol-generating substrate in the sub-cavity closer to the heating element 30 (such as the second sub-cavity 412) does not quickly affect the sub-cavity farther from the heating element 30 (such as the first sub-cavity 411), thereby avoiding the formation of a large cavity and effectively preventing leakage in the atomizer 100. The aerosol-generating substrate consumed with each puff can quickly reduce the pressure in the sub-cavity closer to the heating element 30 (such as the second sub-cavity 412). As the aerosol generating matrix is ​​consumed more and more, the two adjacent sub-cavities (such as the first sub-cavity 411 and the second sub-cavity 412) will balance the pressure, and the sub-cavity close to the heating element 30 (such as the second sub-cavity 412) will be ventilated to the sub-cavity away from the heating element 30 (such as the first sub-cavity 411), and the sub-cavity away from the heating element 30 (such as the first sub-cavity 411) will slowly replenish the aerosol generating matrix to the sub-cavity close to the heating element 30 (such as the second sub-cavity).

[0132] Specifically, in some embodiments, referring to Figure 26, the nebulizer 100 includes a first partition 42, thereby dividing the liquid storage chamber 20 into a first sub-chamber 411 and a second sub-chamber 412. The second sub-chamber 412 is located between the first sub-chamber 411 and the atomization chamber 10. The aerosol-generating matrix in the first sub-chamber 411 first flows into the second sub-chamber 412 and then enters the atomization chamber 10, and the volume of the first sub-chamber 411 is greater than the volume of the second sub-chamber 412.

[0133] More specifically, the first partition 42 has a generally rectangular block-shaped structure and defines a connecting hole 421 and two third lower liquid holes 422. The connecting hole 421 is located in the middle of the first partition 42, allowing one end of the central tube 34 to extend into the heating element 30 through the connecting hole 421. The two third lower liquid holes 422 are located on opposite sides of the connecting hole 421 in the second direction, thereby respectively connecting the first sub-cavity 411 and the second sub-cavity 412. It will be appreciated that the number and size of the third lower liquid holes 422 can be adjusted as needed.

[0134] In this way, the aerosol generating matrix in the second sub-chamber 412 enters the atomizing chamber 10 preferentially, and since the two third lower liquid holes 422 form a certain resistance to the flow of the aerosol generating matrix, the consumption of the aerosol generating matrix in the second sub-chamber 412 will not quickly affect the first sub-chamber 411, thereby avoiding the formation of a large cavity in the liquid storage chamber 20 and effectively preventing the atomizer 100 from leaking.

[0135] As shown in Figure 18, the liquid storage chamber 20 provided in the fourth embodiment of the present disclosure may also include a first-level sub-chamber 413 and at least two second-level sub-chambers 414. All second-level sub-chambers 414 are located between the first-level sub-chamber 413 and the heating element 30. Each second-level sub-chamber 414 is respectively connected to the first-level sub-chamber 413 and the atomization chamber 10, and the volume of each second-level sub-chamber 414 is smaller than the volume of the first-level sub-chamber 413.

[0136] In this way, the aerosol-generating matrix in the primary sub-cavity 413 flows into the heating element 30 through the multiple secondary sub-cavities 414 respectively. The consumption of the aerosol-generating matrix in the secondary sub-cavity 414 will not quickly affect the primary sub-cavity 413, thereby avoiding the formation of a larger cavity and effectively preventing the atomizer 100 from leaking.

[0137] Specifically, in some embodiments, as shown in FIG18 , the lower liquid portion 311 formed on the main shell 31 is provided with two second lower liquid holes 312, and each second lower liquid hole 312 encloses a secondary sub-cavity 414. That is, the atomization chamber 10 includes two secondary sub-cavities 414, and the two secondary sub-cavities 414 are spaced apart on both sides of the central tube 34 along the second direction, and each secondary sub-cavity 414 extends longitudinally along the spacing direction (i.e., the first direction) between the first-level sub-cavity 413 and the heating element 30. In this way, the aerosol generating matrix in the first-level sub-cavity 413 flows to the heating element 30 through the two secondary sub-cavities 414, and the longitudinally extended secondary sub-cavity 414 will form a certain flow space and along-the-way resistance for the aerosol generating matrix, so as to slow down the flow rate of the aerosol generating matrix, thereby reducing the possibility of the aerosol generating matrix generating a large inertial acceleration and overflowing.

[0138] Of course, in some possible implementation schemes, the first partition 42 that is separately processed and formed can also form a longitudinally extending secondary sub-cavity 414, that is, the lower end wall of the first partition 42 can extend to the upper end wall of the mounting seat 321, so as to utilize the third lower liquid hole 422 to enclose the secondary sub-cavity 414.

[0139] As shown in Figures 28 and 29, the atomizer 100 provided in the fourth embodiment of the present disclosure may further include a second partition 43. The second partition 43 is located in the liquid storage chamber 20 and divides the liquid storage chamber 20 into multiple sub-cavities 41. All sub-cavities 41 are arranged in sequence around the central axis of the liquid storage chamber 20, and each sub-cavity 41 is respectively connected to the heating element 30.

[0140] Thus, the second partition 43 divides the liquid storage chamber 20 into a plurality of sub-chambers 41, and the aerosol generating substrate in each sub-chamber 41 flows to the heating element 30. Since the volume of each sub-chamber 41 is relatively small, an excessively large cavity is not formed.

[0141] Specifically in one embodiment, as shown in Figures 28 and 29, the second partition 43 is integrally formed with the central tube 34, and the second partition 43 includes four partitions 431, which are spaced apart around the central tube 34. Each partition 431 extends from the top cover assembly to the atomization chamber 10 along a first direction, and the angle formed between adjacent partitions 431 is 90°. Each partition 431 is connected to the side wall of the central tube 34 on one side in the width direction, and each partition 431 extends to the main shell 31 along the radial direction of the central tube 34 on the other side in the width direction, thereby dividing the liquid storage chamber 20 into four sub-chambers 41, and each sub-chamber 41 is respectively connected to the atomization chamber 10.

[0142] It is understandable that the number, location and volume of each sub-cavity 41 can be set according to factors such as the viscosity of the aerosol generating substrate to meet different liquid requirements.

[0143] The above-mentioned atomizer 100 and electronic atomization device, by dividing the larger liquid storage chamber 20 into multiple smaller sub-chambers 41, can avoid the rapid decrease in the pressure of the liquid storage chamber 20 due to the consumption of the aerosol generating matrix, thereby avoiding the generation of a larger cavity and reducing the possibility of leakage of the atomizer 100.

[0144] It can be understood that Example 1, Example 2, Example 3 and Example 4 focus on the differences between the various embodiments. In some possible implementation schemes, a nebulizer 100 can also be provided, and the nebulizer 100 can have the structure described in at least two of Example 1, Example 2, Example 3 and Example 4. For example, a nebulizer 100 can be provided, which includes at least one ventilation groove, and the liquid storage chamber 20 is divided into a plurality of sub-cavities 41. Specifically, referring to Figure 18, the liquid storage chamber 20 is divided into a first-level sub-cavity 413 and two second-level sub-cavities 414, and the air pressure of each sub-cavity 41 balances each other to reduce the possibility of leakage of the nebulizer 100; and the outer wall of the central tube 34 is provided with a second ventilation groove 342 to increase the space that can store the aerosol matrix overflowing from the liquid storage chamber 20, so as to further reduce the possibility of leakage of the nebulizer 100.
