[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The electronic atomization device is a new type of object that is different from traditional cigarettes. The electronic atomization device is a device that uses electric current to make related components heat up to evaporate the smoke liquid and atomize it into smoke. The related component in the electronic atomization device that heats and atomizes the smoke liquid is the atomization assembly (or atomizer).

[0037] After long-term research, the inventor of this application found that when the existing electronic atomization device is in use, the atomization component is constantly atomizing during operation. As the smoke liquid is continuously consumed, the negative pressure in the cavity storing the smoke liquid in the atomization component continues to increase. The existence of negative pressure causes the smoke liquid to flow poorly, and because the smoke liquid on the heating element is not replenished in time, a burnt smell is generated, which not only damages the product, but also brings a bad user experience. In order to solve the above problems, this application provides the following embodiments based on the many efforts and hard work made by the inventor.

[0038] See also Figure 1 , Figure 1 1 is a schematic diagram of the three-dimensional structure of a cigarette cartridge tube in an embodiment of the present invention. On one hand, the present invention provides a cigarette cartridge tube 10 for an atomization assembly, the cigarette cartridge tube 10 forms a liquid storage chamber 11 for storing cigarette liquid, and the cavity wall surrounding the liquid storage chamber 11 includes at least an elastic wall portion, which can be deformed under the action of air differential pressure and can be restored to an undeformed position when the air differential pressure is eliminated.

[0039] In this embodiment, the cavity wall surrounding the liquid storage cavity 11 includes at least an elastic wall portion. When the smoke liquid in the liquid storage cavity 11 is consumed, the negative pressure of the cavity of the liquid storage cavity 11 increases. Under the action of the air differential pressure, the elastic wall portion is deformed, thereby balancing the pressure in the liquid storage cavity 11, so that the smoke liquid in the liquid storage cavity 11 can flow out smoothly, avoiding the generation of burnt smell, thereby improving the user experience. At the same time, after the elastic wall portion is deformed, the outside air enters the liquid storage cavity 11 through the heating component, so that the elastic wall portion gradually returns to the undeformed position.

[0040] Specifically, in the present embodiment, the air differential pressure refers to the differential pressure between the pressure inside the liquid storage chamber 11 and the atmospheric pressure outside the liquid storage chamber. When the e-liquid in the liquid storage chamber 11 is consumed, the pressure inside the liquid storage chamber 11 decreases, and the differential pressure between the pressure inside the liquid storage chamber 11 and the atmospheric pressure increases, that is, the negative pressure of the liquid storage chamber 11 increases, and the pressure of the air acting on the side wall of the liquid storage chamber 11 increases.

[0041] Among them, see Figure 2 and Figure 3 , Figure 2 yes Figure 1 The cross-sectional structure diagram of the cigarette bomb tube in FIG. Figure 3 yes Figure 1 In this embodiment, the cigarette cartridge tube 10 includes a first tube wall 12 for surrounding a liquid storage chamber 11, and a mounting groove 122 communicating with the liquid storage chamber 11 is formed on the first tube wall 12. The cigarette cartridge tube 10 also includes an elastic membrane 13 constituting an elastic wall portion, and the elastic membrane 13 is connected to the first tube wall 12 and covers the mounting groove 122.

[0042] Specifically, in the present embodiment, the first tube wall 12 is annularly arranged to enclose the cigarette bomb tube 10, and a mounting groove 122 penetrating the first tube wall 12 is provided on the first tube wall 12. The elastic membrane 13 is arranged on the side of the first tube wall 12 away from the liquid storage chamber 11, connected to the first tube wall 12, and covers the mounting groove 122. Therefore, when the smoke liquid in the liquid storage chamber 11 is consumed, the elastic membrane 13 shrinks to the side close to the liquid storage chamber 11 under the action of the external atmospheric pressure, thereby reducing the volume of the liquid storage chamber 11 to balance the pressure difference between the pressure inside the liquid storage chamber 11 and the atmospheric pressure, so as to facilitate the liquid discharge. At the same time, the outside air enters the liquid storage chamber 11 through the heating component, so that the elastic membrane 13 gradually expands to the side away from the liquid storage chamber 11, and then returns to the undeformed position.

[0043] Among them, the number of the mounting grooves 122 can be one, two or more, and the shape of the mounting grooves 122 can also be rectangular, circular, elliptical, etc., which can be specifically set according to the surface shape of the first tube wall 12 and the concentration of the smoke liquid in the liquid storage chamber 11, and the present invention does not make specific limitations.

[0044] In this embodiment, if Figure 3 As shown, there is one mounting groove 122 and the shape of the mounting groove 122 is rectangular. The mounting groove 122 is arranged on a surface with a larger area of ​​the first tube wall 12 to increase the size of the mounting groove 122 and further increase the size of the elastic membrane 13 to facilitate deformation of the elastic membrane 13.

[0045] like Figure 4 As shown, Figure 4: is a schematic diagram of the exploded structure of the cigarette cartridge tube in another embodiment of the present invention. In another embodiment, the number of mounting grooves 122 is two, and the two mounting grooves 122 are provided on opposite sides of the first tube wall 12. The number of elastic membranes 13 is two, and each elastic membrane 13 is provided corresponding to one mounting groove 122. In this embodiment, by providing mounting grooves 122 on opposite sides of the first tube wall 12, the opposite sides of the cigarette cartridge tube 10 can be subjected to uniform force, and compared with only one elastic membrane 13, providing more elastic membranes 13 can also reduce the force of the differential pressure on one elastic membrane 13, thereby protecting the elastic membrane 13.

[0046] Among them, Figure 4 In the illustrated embodiment, the mounting grooves 122 disposed on opposite sides of the first tube wall 12 are rectangular grooves of the same shape and size. In other embodiments, mounting grooves 122 of the same or different shapes or the same or different sizes may be disposed on opposite sides of the first tube wall 12 as required, which is not specifically limited in this embodiment.

[0047] Furthermore, if Figure 3 As shown, the mounting groove 122 includes a first groove body 121 and a second groove body 123 which are nested. The first groove body 121 is arranged on a side away from the liquid storage chamber 11, and the second groove body 123 is opened on the bottom surface of the first groove body 121. The elastic membrane 13 is located in the first groove body 121 and is connected to the bottom surface of the first groove body 121.

[0048] Specifically, in this embodiment, the cross-sectional area of ​​the first groove body 121 is greater than the cross-sectional area of ​​the second groove body 123, and the outer contour of the first groove body 121 surrounds the outer contour of the second groove body 123, so that the second groove body 123 can be opened on the bottom surface of the first groove body 121 to form a nested first groove body 121 and a second groove body 123.

[0049] In this embodiment, by setting the cross-sectional area of ​​the second groove body 123 to be smaller than the cross-sectional area of ​​the first groove body 121, a recessed groove for accommodating the elastic membrane 13 can be formed on the first groove body 121, so that the elastic membrane 13 can be accommodated in the first groove body 121. On the one hand, the elastic membrane 13 can be protected, and on the other hand, the shell that is sleeved on the outside of the cigarette bomb tube 10 can be avoided.

[0050] Optionally, in one embodiment, the elastic membrane 13 and the bottom surface of the first groove body 121 can be fixed by bonding, that is, a sealant is applied to the bottom surface of the first groove body 121, and then the elastic membrane 13 is attached to the bottom surface of the first groove body 121 to achieve sealing of the liquid storage chamber 11.

[0051] In another embodiment, the melting point of the elastic membrane 13 is lower than the melting point of the first tube wall 12, and the elastic membrane 13 is connected to the first tube wall 12 by integral injection molding. Specifically, the first tube wall 12 is firstly processed by injection molding, and the installation groove 122 is opened on the first tube wall 12, and then the first tube wall 12 with the installation groove 122 is put into the injection molding machine again, and the elastic membrane 13 is formed by injection molding in the first groove body 121 using a material with a lower melting point. Since the melting point of the first tube wall 12 is relatively high, the first tube wall 12 will not be affected during the process of injection molding the elastic membrane 13. The first tube wall 12 formed by injection molding in this way and the elastic membrane 13 connected to the first tube wall 12 have a relatively high connection strength.

[0052] In this embodiment, the first tube wall 12 can be formed by injection molding of a hard material, and the elastic membrane 13 can be formed by injection molding of a soft material. For example, the first tube wall 12 can be made of PVC (Polyvinyl chloride) material, and the elastic membrane 13 can be made of silicone material.

[0053] In another embodiment, the first tube wall 12 may be formed by thermosetting plastics. Thermosetting plastics generally refer to plastics that are processed by hot pressing and cannot be processed again after forming. For example, phenolic plastics, polyurethane plastics, epoxy plastics, unsaturated polyester plastics, furan plastics, silicone resins, acrylic resins, etc. and their modified resins may be used as related plastics for the body. In this embodiment, by using thermosetting plastics to form the first tube wall 12, deformation or melting of the first tube wall 12 can be avoided during the process of injection molding the elastic film 13, so as to facilitate processing.

[0054] Furthermore, in this embodiment, the thickness of the elastic membrane 13 corresponds to the depth of the first groove 121, so that the surface of the first tube wall 12 where the first groove 121 is opened is flush with the surface of the elastic membrane 13 away from the liquid storage cavity 11. By setting the surface of the first tube wall 12 where the first groove 121 is opened to be flush with the surface of the elastic membrane 13 away from the liquid storage cavity 11, the elastic membrane 13 can be protected, and the surface of the cigarette bomb tube 10 can be made smoother, making its appearance more beautiful.

[0055] Another aspect of the present invention further provides an atomization assembly 100, see Figure 5 and Figure 6 , Figure 5 is a schematic diagram of the exploded structure of an atomization assembly in another embodiment of the present invention, Figure 6 yes Figure 5The cross-sectional structural diagram of the atomizer assembly in FIG. The atomizer assembly 100 includes a heating assembly 20 and a cartridge tube 10. The cartridge tube 10 includes a first tube wall 12 for surrounding a liquid storage chamber 11. The heating assembly 20 is connected to the liquid storage chamber 11 to receive the smoke liquid supplied by the liquid storage chamber 11 and heat the received smoke liquid to atomize and form smoke.

[0056] Specifically, in this embodiment, the heating component 20 may be at least partially located in the liquid storage chamber 11, for example, embedded into the first tube wall 12 from one end of the liquid storage chamber 11 to seal one end of the liquid storage chamber 11. The smoke liquid in the liquid storage chamber 11 is in contact with the heating component 20, and when the heating component 20 generates heat, the smoke liquid in contact therewith may be heated to be atomized to form smoke.

[0057] In another embodiment, the heating component 20 may be completely located below the first tube wall 12 , and sealing members of different shapes may be used to connect the liquid storage chamber 11 and the heating component 20 , so that the heating component 20 can receive the e-liquid supplied by the liquid storage chamber 11 .

[0058] Among them, in this embodiment, the structure of the cigarette cartridge tube 10 is the same as the structure of the cigarette cartridge tube 10 described in the above embodiment. Please refer to the description in the above embodiment and will not be repeated here.

[0059] Furthermore, if Figure 5 As shown, the heating component 20 includes a porous ceramic liquid conductor 22 and a heating element (not shown). In this embodiment, the porous ceramic liquid conductor 22 is made of a porous ceramic material, etc. The porous ceramic material is, for example, a ceramic material sintered at high temperature by components such as aggregates, binders and pore-forming agents, and has a large number of porous structures connected to each other and to the surface of the material. The porous ceramic material has excellent properties such as high porosity, stable chemical properties, large specific surface area, low volume density, low thermal conductivity, and high temperature resistance and corrosion resistance.

[0060] This embodiment, by setting an elastic membrane 13 on the cigarette bomb tube 10, can avoid the problem that the tortuous porous structure of the porous ceramic liquid-conducting liquid 22 cannot be effectively ventilated when the liquid storage chamber 11 generates a negative pressure due to the user inhaling smoke, thereby avoiding the problem that the porous ceramic liquid-conducting liquid 22 cannot flow smoothly due to the inability of the porous structure to ventilate, causing a burnt smell, etc., thereby improving the atomization efficiency of the atomization component 100 and improving the user experience. At the same time, the outside air enters the liquid storage chamber 11 through the porous structure inside the porous ceramic liquid-conducting liquid 22, which can make the elastic membrane 13 gradually expand to the side away from the liquid storage chamber 11, which is used to balance the differential pressure inside and outside the liquid storage chamber 11, and then restore the elastic membrane 13 to the undeformed position.

[0061] Among them, in this embodiment, if Figure 5 and Figure 6As shown, the porous ceramic liquid-conducting body 22 is at least partially located in the liquid storage chamber 11, and a liquid-conducting groove 221 is formed on the side of the porous ceramic liquid-conducting body 22 facing the liquid storage chamber 11, and the liquid-conducting groove 221 is used to hold the smoke liquid. The heating element is arranged on the side of the porous ceramic liquid-conducting body 22 away from the liquid-conducting groove 221, and is used to heat the smoke liquid.

[0062] Specifically, the liquid conducting groove 221 is formed by a side surface (which can be called the top surface 223) of the porous ceramic liquid conducting liquid 22 facing the liquid storage chamber 11, which is recessed into the interior of the porous ceramic liquid conducting liquid 22. On a cross section parallel to the top surface 223 of the porous ceramic liquid conducting liquid 22, the cross-sectional area of ​​the liquid conducting groove 221 gradually decreases along the depth direction of the liquid conducting groove 221. The liquid conducting groove 221 is used to receive the smoke liquid from the liquid storage chamber 11 and flow to the heating element through the porous structure. By forming the liquid conducting groove 221, this embodiment can facilitate the holding of the smoke liquid, while increasing the contact area between the smoke liquid and the porous ceramic liquid conducting liquid 22, thereby improving the flow efficiency and speed of the smoke liquid.

[0063] Among them, the heating element is located on the bottom surface 225 of the porous ceramic liquid-conducting body 22 opposite to the liquid-conducting groove 221. The smoke liquid flows through the porous structure in the liquid-conducting groove 221 to the heating element. The heating element is used to connect to the power supply, and then generate heat under the action of the current, and atomize the smoke liquid into smoke. In this embodiment, the heating element can be at least one of a heating coating, a heating circuit, a heating sheet or a heating net. For example, the heating element is a heating resistor wire. After the power is turned on, the current flows through the heating element to generate heat, thereby atomizing the smoke liquid that flows through the porous structure to the bottom surface 225 of the porous ceramic liquid-conducting body 22 to produce smoke. In this embodiment, the heating element can be arranged in a zigzag shape.

[0064] Furthermore, if Figure 6 As shown, the heating component 20 further includes an electrode needle 26, which is inserted or fixed on the bottom surface 225 of the porous ceramic liquid conductor 22 and extends in a direction away from the bottom surface 225. The electrode needle 26 is electrically connected to the heating element. The electrode needle 26 is used to connect a power source to conduct current to the heating element. The number of electrode needles 26 can be 2 to connect the positive and negative poles of the power source. The power source is, for example, a battery.

[0065] Alternatively, if Figure 6 As shown, the heating component 20 further includes a first seal 28 , which abuts between the porous ceramic liquid conductor 22 and the first tube wall 12 to achieve sealing, and is used to prevent the smoke liquid flowing from the liquid storage chamber 11 to the porous ceramic liquid conductor 22 from leaking.

[0066] In this embodiment, the outer side surface of the porous ceramic liquid-conducting body 22 is provided with steps on two opposite sides, forming a step surface 227 away from the top surface 223. When the first sealing member 28 is sleeved on the porous ceramic liquid-conducting body 22, it covers the edge portion of the top surface 223 and part of the outer side surface 229 and the step surface 227, so that when the porous ceramic liquid-conducting body 22 is embedded in the first tube wall 12, the first sealing member 28 can play a good sealing role.

[0067] Continue reading Figure 5 and Figure 6 The first sealing member 28 is, for example, provided in a sleeve shape, and includes a top wall 282, and the top wall 282 surrounds the liquid-conducting groove 221 and is provided on the top surface 223 of the porous ceramic liquid-conducting body 22, and the liquid-conducting groove 221 is exposed. Further, the first sealing member 28 may also include a side wall 284 connected to the outer edge of the top wall 282, and the side wall 284 is located on the outer periphery of the outer side surface 229 of the porous ceramic liquid-conducting body 22, and is sandwiched between the outer side surface 229 and the inner surface of the first tube wall 12 for sealing.

[0068] Specifically, when the first sealing member 28 is sleeved on the porous ceramic liquid-conducting body 22, the top wall 282 contacts the top surface 223 of the porous ceramic liquid-conducting body 22, and the side wall 284 contacts the outer periphery of the outer side surface 229 of the porous ceramic liquid-conducting body 22 to perform sealing. By providing the top wall 282 and the side wall 284 of the first sealing member 28, the sealing effect of the first sealing member 28 can be effectively guaranteed, and the porous ceramic liquid-conducting body 22 can be protected at the same time.

[0069] Furthermore, the first seal 28 further includes a bottom wall 286, which is disposed on two opposite sides of the first seal 28 and connected to an end of the side wall 284 of the first seal 28 away from the top wall 282, and the bottom wall 286 is spaced apart from and disposed opposite to the top wall 282. When the first seal 28 is sleeved on the porous ceramic liquid-conducting body 22, the bottom wall 286 covers the step surface 227. In this embodiment, the first seal 28 surrounds a portion of the porous ceramic liquid-conducting body 22 through the top wall 282, the side wall 284 and the bottom wall 286, so that the first seal 28 and the porous ceramic liquid-conducting body 22 can be more firmly matched.

[0070] Furthermore, if Figure 6 As shown, a flange 124 is provided on the inner surface of the first tube wall 12, and one end of the heating component 20 abuts against the flange 124. The atomizer assembly 100 also includes a base 30, which is connected to one end of the cigarette cartridge tube 10 adjacent to the heating component 20, and the other end of the heating component 20 is supported on the base 30.

[0071] In one embodiment, the flange 124 may include a plurality of flanges 124 , and the plurality of flanges 124 are arranged at intervals along the circumference of the inner surface of the first tube wall 12 to stop the heating component 20 .

[0072] In this embodiment, an annular flange 124 is provided on the circumference of the inner surface of the first tube wall 12 to stop the heating component 20 and facilitate the sealing between the flange 124 and the heating component 20. The first sealing member 28 is clamped between the flange 124 and the porous ceramic liquid-conducting body 22 to simultaneously contact the flange 124 and the porous ceramic liquid-conducting body 22 for sealing, further preventing the smoke liquid in the liquid storage chamber 11 from leaking when flowing onto the porous ceramic liquid-conducting body 22.

[0073] In this embodiment, the flange 124 is integrally formed on the inner surface of the first tube wall 12. Of course, in other embodiments, the flange 124 and the cigarette cartridge tube 10 may not be integrally formed, and the flange 124 is, for example, detachably disposed on the inner surface of the first tube wall 12. The outer edge of the flange 124 is surrounded by a hole, that is, the middle part of the flange 124 is a hollow hole, so that the smoke liquid in the liquid storage chamber 11 flows through the hole to the porous ceramic liquid guide 22.

[0074] Optionally, the protruding direction of the flange 124 may be perpendicular to the inner surface of the first tube wall 12 adjacent to the heating component 20 or perpendicular to the axial direction of the cigarette bomb tube 10 .

[0075] The base 30 is fixedly connected to one end of the cartridge tube 10 adjacent to the heating component 20. In this embodiment, the base 30 supports the porous ceramic liquid conductor 22 so that the porous ceramic liquid conductor 22 and the first sealing member 28 can be embedded in the liquid storage chamber 11 and abut against the flange 124 for sealing.

[0076] Specifically, see Figure 5 and Figure 6 The cigarette bomb tube 10 includes a second tube wall 14 located on both sides of the first tube wall 12, and the second tube wall 14 is respectively connected to the outer surface of the first tube wall 12. In this embodiment, on the side adjacent to the heating component 20, the extension length of the second tube wall 14 can be greater than the extension length of the first tube wall 12. The base 30 is fixedly connected to the second tube wall 14, and the heating component 20 is partially embedded in the space of the first tube wall 12 and is located between the base 30 and the flange 124. Among them, in this embodiment, the cigarette bomb tube 10 is integrally formed, that is, the first tube wall 12 and the second tube wall 14 are integrally formed.

[0077] In this embodiment, the base 30 and the second tube wall 14 can be connected by snapping, the base 30 is provided with a snapping portion 32, and a snapping groove 142 is provided at a corresponding position on the inner surface of the second tube wall 14. When connecting, the snapping portion 32 is inserted into the snapping groove 142, and the fixed connection is achieved by the snapping fit between the snapping portion 32 and the snapping groove 142.

[0078] Optionally, the base 30 is provided with a support column 34 protruding from one side toward the porous ceramic liquid-conducting body 22. The number of the support columns 34 is, for example, two, and the two support columns 34 are arranged opposite to each other. When the base 30 and the second tube wall 14 are fixed, the support columns 34 can be used to support the porous ceramic liquid-conducting body 22. The support columns 34 can support the steps on both sides of the porous ceramic liquid-conducting body 22 and abut against the step surface 227.

[0079] Furthermore, if Figure 5 As shown, the atomizer assembly 100 further includes a rear cover 80, and the rear cover 80 has a receiving space. When the rear cover 80 is covered on the base 30, the base 30 is received in the receiving space, and the base 30 can be effectively protected.

[0080] Furthermore, if Figure 5 and Figure 6 As shown, the atomizer assembly 100 also includes a second seal 40, which is disposed between the base 30 and the cigarette bomb tube 10 for sealing, thereby avoiding problems such as smoke leakage. In this embodiment, the buckle portion 32 of the base 30 passes through the second seal 40 and is fixedly connected to the buckle groove 142 of the second tube wall 14, and the through structure of the base 30 and the second seal 40 can make the sealing effect of the second seal 40 better. In this embodiment, a gap or space is formed between the second seal 40 and the bottom surface 225 of the porous ceramic liquid conductor 22, and the smoke generated by the heating element after heating is generally located in the space.

[0081] Alternatively, if Figure 6 As shown, the base 30 is provided with a mounting hole 36, and in this embodiment, the mounting hole 36 can pass through the base 30 in the axial direction. The second sealing member 40 is partially accommodated in the mounting hole 36 and also serves as a seal. An electrode seat 50 is provided on the side of the second sealing member 40 that is located in the mounting hole 36 and is away from the heating component 20. For example, the electrode seat 50 is partially inserted into the second sealing member 40 for fixing. One end of the electrode needle 26 of the heating component 20 is fixedly connected to the heating element, and the other end of the electrode needle 26 passes through the second sealing member 40 to connect to the electrode seat 50, and the electrode seat 50 is used to connect to a power source.

[0082] In this embodiment, the end of the electrode holder 50 away from the heating component 20 exposes a side of the base 30 away from the heating component 20 to form a contact point, which can be connected to a power source to conduct current. Further, the atomizer assembly 100 may include an electrode fixing member 60, which is sleeved on the end of the electrode holder 50 away from the heating component 20, and is used to fix and position the two electrode holders 50. The end of the electrode holder 50 away from the heating component 20 further exposes the electrode fixing member 60 to form a contact point. In this embodiment, the electrode fixing member 60 can be arranged in a sheet shape.

[0083] In this embodiment, the second tube wall 14 is connected to the outer surface of the first tube wall 12 in a bent shape, so as to respectively form an air inlet channel 144 with the first tube wall 12. In this embodiment, there are two second tube walls 14, and each second tube wall 14 and the first tube wall 12 form an air inlet channel 144, that is, the air inlet channel 144 is located on opposite sides of the liquid storage chamber 11, and is used to guide the air outside the atomization component 100 to the position of the heating component 20.

[0084] Furthermore, if Figure 5 As shown, an air outlet channel 146 is opened on the second tube wall 14 , and the air outlet channel 146 is connected to the air inlet channel 144 for discharging the smoke atomized by the heating component 20 .

[0085] Specifically, the air outlet channel 146 is arranged in parallel with the air inlet channel 144 and is connected to the air inlet channel 144. The air inlet channel 144 is used to guide the air outside the atomization component 100 to the position of the heating component 20. The airflow formed by the air brings the smoke formed by the heating component 20 into the air outlet channel 146, and then is guided by the air outlet channel 146 to the inhalation position, such as the mouthpiece.

[0086] See also Figure 5 and Figure 6 The atomizer assembly 100 further includes an upper cover assembly 70, which is disposed at one end of the cigarette bomb tube 10 away from the heating assembly 20. The upper cover assembly 70 is at least used to further guide the smoke in the air outlet channel 146 to the suction position for use by the user.

[0087] In this embodiment, the upper cover assembly 70 includes an exhaust pipe 72, a flue upper cover 74 and a third sealing member 76. The third sealing member 76 is disposed between the flue upper cover 74 and one end of the smoke bomb tube 10 away from the heating component 20 to seal the liquid storage chamber 11. The flue upper cover 74 has a condensation space 742. The condensation space 742 connects the air outlet channel 146 and the exhaust pipe 72 for accumulating condensate of smoke. The exhaust pipe 72 is embedded in the flue upper cover 74 and connected to the condensation space 742.

[0088] In this embodiment, the condensation space 742 has a certain height and width. Specifically, when the smoke in the air outlet channel 146 flows toward the exhaust pipe 72 along with the air flow, part of the smoke will condense in the condensation space 742 and accumulate in the condensation space 742 to prevent it from being directly inhaled and entering the user's mouth through the exhaust pipe 72. The condensation space 742 can be realized by making the flue cover 74 have a certain height; that is, when the flue cover 74 has a certain height, the top wall of the flue cover 74 can form a gap with the third sealing member 76, and this gap can serve as the condensation space 742.

[0089] Furthermore, an air guide channel can be formed between the first seal and the cigarette bomb tube, and air can be guided into the liquid storage chamber while the first seal achieves sealing, so as to balance the differential pressure inside and outside the liquid storage chamber, improve the problem of poor liquid discharge caused by the negative pressure generated by the continuous consumption of the liquid in the liquid storage chamber, enhance the user experience, and facilitate the elastic membrane to recover its deformation.

[0090] An air guide channel may be formed between the first seal and the inner surface of the first tube wall. For example, a protrusion structure or a groove structure may be provided on the inner surface of the first tube wall facing the heating component, and when the first seal abuts against the inner surface of the first tube wall, the protrusion structure or the groove structure may allow a gap to exist between the first seal and the first tube wall, thereby forming an air guide channel.

[0091] In another embodiment, a first gas guiding groove may be formed on the inner side of the first sealing member facing the porous ceramic liquid-conducting body, and the first gas guiding groove and the top surface of the porous ceramic liquid-conducting body form a gas guiding channel.

[0092] See also Figure 7 , Figure 7 The present invention also provides an electronic atomization device 300, which includes a power supply component 200 and an atomization component 100, wherein the power supply component 200 is used to supply power to the atomization component 100 so that the atomization component 100 can atomize the smoke liquid into smoke.

[0093] In this embodiment, the structure of the atomizer assembly 100 is the same as the structure of the atomizer assembly 100 in the above embodiment. Please refer to the description in the above embodiment and will not be repeated here.

[0094] In summary, those skilled in the art can easily understand that in the embodiment of the present invention, the cavity wall surrounding the liquid storage cavity 11 includes at least an elastic wall portion. When the smoke liquid in the liquid storage cavity 11 is consumed, the negative pressure of the cavity of the liquid storage cavity 11 increases. Under the action of the air differential pressure, the elastic wall portion is deformed, thereby balancing the pressure in the liquid storage cavity 11, so that the smoke liquid in the liquid storage cavity 11 can flow out smoothly, avoiding the generation of burnt smell, thereby improving the user experience. At the same time, after the elastic wall portion is deformed, the outside air enters the liquid storage cavity 11 through the heating component, so that the elastic wall portion gradually returns to the undeformed position.

[0095] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
