Description

Technical Field

[0001] The present invention relates to the field of atomization, and more specifically, to a composite liquid guide cotton, a heating component, an atomizer, and an electronic atomization device. Background Art

[0002] An electronic atomization device mainly consists of an atomizer and a power supply device. The power supply device is used to supply power to the atomizer, and the atomizer can heat and atomize the atomization liquid stored therein after being powered on. Generally, the atomizer includes a liquid guide cotton and a heating element in contact with the liquid guide cotton. The atomization liquid stored in the atomizer is adsorbed by the liquid guide cotton, and the heating element heats and atomizes the atomization liquid adsorbed by the liquid guide cotton after being powered on. If the temperature resistance value of the liquid guide cotton is not enough, the problem of scorching is likely to occur. And since the absorption and conduction of the atomization liquid in the liquid guide cotton both require a certain amount of time, if the liquid absorption speed and liquid conduction speed of the liquid guide cotton are too slow, it will lead to the atomized gas being too dry and light after atomization, the fragrance release being insufficient, and even dry burning occurring and generating a burnt smell in severe cases.

[0048] Figures 1-3 An electronic atomization device 1 in the first embodiment of the present invention is shown. The electronic atomization device 1 may be generally cylindrical in some embodiments, and may include a power supply device 200 and an atomizer 100 longitudinally disposed above the power supply device 200. The atomizer 100 is used to contain atomization liquid and heat and atomize the atomization liquid to generate aerosol, and the power supply device 200 is used to supply power to the atomizer 100. It can be understood that in other embodiments, the electronic atomization device 1 is not limited to being cylindrical, and it may also be in other shapes such as oval columnar, square columnar, flat columnar, etc.

[0049] The power supply device 200 may include a housing 80 and a battery 90 received in the housing 80. The battery 90 is electrically connected to the heating component 30 of the atomizer 100 and is used to supply power to the heating component 30. The housing 80 may be generally cylindrical, the battery 90 may be received in the lower part of the housing 80, and a receiving space 81 for receiving the atomizer 100 is formed in the upper part of the housing 80.

[0050] As Figures 3-4 shown, the atomizer 100 may include a liquid reservoir 10, a base 20, a heating component 30, a ventilation pipe 40, an end cap 50, a liquid absorbing member 60, and a mouthpiece assembly 70 in some embodiments.

[0051] The liquid reservoir 10 is used to store the atomizing liquid, and it may include a liquid storage shell 11. In this embodiment, the liquid storage shell 11 is in the shape of a cylindrical tube with openings at both ends. The air vent pipe 40 is longitudinally disposed through the liquid storage shell 11 and can be coaxially arranged with the liquid storage shell 11. An annular liquid storage space 110 is formed between the outer wall surface of the air vent pipe 40 and the inner wall surface of the liquid storage shell 11, and the inner wall surface of the air vent pipe 40 defines an air flow channel 41. In some embodiments, the air vent pipe 40 can be a fiberglass tube to reduce costs. In other embodiments, the air vent pipe 40 can also be made of other materials such as plastic or metal.

[0052] In some embodiments, the liquid reservoir 10 may further include a liquid storage member 12 disposed in the liquid storage space 110 for absorbing and storing a certain amount of atomizing liquid. The liquid storage member 12 is in the shape of a circular column, and a through hole 120 for the air vent pipe 40 to pass through is longitudinally formed thereon. The liquid storage member 12 is usually a liquid storage cotton so as to be able to absorb and store more atomizing liquid. In some embodiments, a bayonet 121 is formed on the side wall of the liquid storage member 12, so that the liquid storage member 12 is in the shape of a C-shaped cylinder, which is convenient for clamping the liquid storage member 12 around the air vent pipe 40.

[0053] The heating component 30 is disposed in the liquid storage shell 11 and contacts the liquid storage member 12, and is used for heating and atomizing the atomizing liquid stored in the liquid storage member 12 after being powered on. An atomizing cavity 330 may be longitudinally formed on the heating component 30, and the atomizing cavity 330 can be communicated with the lower end of the air flow channel 41. The heating component 30 may include a composite liquid guiding cotton 31 that contacts the liquid storage member 12 for absorbing the atomizing liquid from the liquid storage member 12, a heating element 33 disposed on the composite liquid guiding cotton 31 for heating and atomizing the atomizing liquid after being powered on, and a heating base 32 for supporting the composite liquid guiding cotton 31.

[0054] As Figures 5-6 shown, in some embodiments, the composite liquid guiding cotton 31 may include at least one heat-resistant layer 311, at least one first isolation layer 312, at least one rapid liquid guiding layer 313, and at least one second isolation layer 314 that are sequentially laminated.

[0055] The heat-resistant layer 311 can respectively contact the liquid storage member 12 and the heating element 33, and it can be made of a material with fast liquid absorption and high temperature resistance to prevent the generation of burnt smell during heating. In this embodiment, there is one layer of the heat-resistant layer 311 and it is made of linen cotton, which has the advantages of fast liquid absorption, fast absorption and drying, high temperature resistance, not easy to generate burnt smell, and antibacterial. The weight of the linen cotton per square meter before being immersed in liquid can be 45 grams ± 10%. The temperature resistance value of the linen cotton when soaked with atomizing liquid is above 200 °C, preferably above 300 °C.

[0056] The fast liquid guiding layer 313 has a high liquid guiding rate, and its liquid guiding rate is better than that of the heat-resistant layer 311, the first isolation layer 312, and the second isolation layer 314. In this embodiment, the fast liquid guiding layer 313 has two layers and can be made of wood pulp cotton, and the weight per square meter of the wood pulp cotton before being immersed in liquid can be 50 grams ± 10%. By stacking two layers of wood pulp cotton, the liquid guiding speed can be made faster. In other embodiments, the fast liquid guiding layer 313 can also be provided with one layer or multiple layers.

[0057] The first isolation layer 312 and the second isolation layer 314 can be made of materials that can isolate odors, have a fast liquid guiding rate, and have a high liquid storage capacity. The materials of the first isolation layer 312 and the second isolation layer 314 can be the same or different. The first isolation layer 312 and the second isolation layer 314 are respectively arranged on two opposite sides of the fast liquid guiding layer 313, and can isolate the odors that may be generated by the material of the fast liquid guiding layer 313 itself, so that the fast liquid guiding layer 313 can have a wider range of material selection. Therefore, when selecting the material of the fast liquid guiding layer 313, only its liquid guiding rate needs to be considered without worrying about whether it will generate odors. In addition, the liquid storage capacity of the first isolation layer 312 and the second isolation layer 314 is higher than that of the fast liquid guiding layer 313, that is, the saturated liquid absorption amount per unit volume of the first isolation layer 312 and the second isolation layer 314 is greater than that of the fast liquid guiding layer 313 per unit volume. In some embodiments, the liquid storage capacity of the first isolation layer 312 and the second isolation layer 314 is higher than that of the heat-resistant layer 311, and the liquid storage capacity of the heat-resistant layer 311 is higher than that of the fast liquid guiding layer 313. The first isolation layer 312 and the second isolation layer 314 can store a relatively large amount of atomized liquid, further avoiding the occurrence of dry burning. In this embodiment, the first isolation layer 312 and the second isolation layer 314 each have one layer and are both made of non-woven fabric. The weight per square meter of the non-woven fabric before being immersed in liquid can be 75 grams ± 10%, and the thickness before being immersed in liquid can be 0.3 - 0.4 mm. Using 75-gram non-woven fabric can increase the liquid storage capacity of the composite liquid guiding cotton 31. In other embodiments, the first isolation layer 312 and the second isolation layer 314 can also be made of other materials such as mixed cotton (a mixture of linen cotton and non-woven fabric), non-woven fabric with black dots (cotton seeds), and tea fiber.

[0058] The composite liquid guiding cotton 31 can include a first liquid guiding part 315, a second liquid guiding part 316, a first extension part 317, and a second extension part 318.

[0059] The cross-section of the first liquid guiding part 315 is in the shape of an annular ring with an opening, and it has a first end 3151 and a second end 3152 that is circumferentially opposite to the first end 3151. The first liquid guiding part 315 includes, from the inner layer to the outer layer, a heat-resistant layer 311, a first isolation layer 312, a fast liquid guiding layer 313, and a second isolation layer 314 in sequence. The inner wall surface of the first liquid guiding part 315 defines a first cavity 3150, and this first cavity 3150 forms an atomization cavity 330. The heating element 33 can be arranged on the inner wall surface of the first liquid guiding part 315, that is, the heating element 33 is arranged on the heat-resistant layer 311 of the first liquid guiding part 315. In this embodiment, the heating element 33 can be a cylindrical heating sheet, and in other embodiments, the heating element 33 can also be other structures such as a spiral heating wire or a heating film.

[0060] The second liquid guiding part 316 is in the shape of an annular ring and is arranged on the periphery of the first liquid guiding part 315, and it can be coaxially arranged with the first liquid guiding part 315. The second liquid guiding part 316 includes, from the outer layer to the inner layer, a heat-resistant layer 311, a first isolation layer 312, a fast liquid guiding layer 313, and a second isolation layer 314 in sequence. The inner diameter of the second liquid guiding part 316 is larger than the outer diameter of the first liquid guiding part 315, and an annular second cavity 3160 is formed between the inner wall surface of the second liquid guiding part 316 and the outer wall surface of the first liquid guiding part 315, and this second cavity 3160 can be used for the heating base 32 to pass through it. That is, the inner wall surface of the heating base 32 contacts the second isolation layer 314 on the outermost layer of the first liquid guiding part 315, and the outer wall surface of the heating base 32 contacts the second isolation layer 314 on the innermost layer of the second liquid guiding part 316.

[0061] The heating base 32 can be in the shape of a circular tube, and it can include a base body 321 and an extension part 322 that extends upward from the upper end of the base body 321. The inner diameters of the base body 321 and the extension part 322 are equal, and the outer diameter of the base body 321 can be larger than the outer diameter of the extension part 322, so that a stepped surface 323 is formed at the junction of the base body 321 and the extension part 322. The lower end of the ventilation pipe 40 can be sleeved outside the extension part 322, the lower end face of the ventilation pipe 40 can abut against the stepped surface 323, and the outer diameter of the ventilation pipe 40 can be equal to the outer diameter of the base body 321.

[0062] The first liquid guiding part 315 can be received in the base body 321, and at least one liquid inlet hole 3210 is further formed on the side wall of the base body 321, so that the atomization liquid in the liquid storage member 12 can enter the base body 321 through the at least one liquid inlet hole 3210 and be absorbed by the first liquid guiding part 315. In this embodiment, there are two liquid inlet holes 3210, and the two liquid inlet holes 3210 can be symmetrically arranged along the circumference of the base body 321.

[0063] At least one slot 3211 may be provided on the side wall of the heating base 32. The slot 3211 may extend axially downward from the upper end face of the extension portion 322. The first end 3151 and the second end 3152 of the first liquid guiding portion 315 may pass through the slot 3211. In addition, the slot 3211 also has the function of connecting the liquid storage member 12 and the first liquid guiding portion 315. In this embodiment, there are two slots 3211, and the two slots 3211 may be symmetrically arranged along the circumferential direction of the heating base 32, and the slot 3211 and the liquid inlet hole 3210 may be arranged at a 90-degree angle along the circumferential direction of the heating base 32.

[0064] The first end 3151 of the first liquid guiding portion 315 passes through the slot 3211 and is connected to the circumferential end of the second liquid guiding portion 316. The second end 3152 of the first liquid guiding portion 315 extends radially outward along the slot 3211 to form a first extension portion 317. The circumferential other end of the second liquid guiding portion 316 is connected to the second extension portion 318, and the extending direction of the second extension portion 318 may be the same as the extending direction of the first extension portion 317. The second extension portion 318 and the first extension portion 317 may be joined together and then snapped into the bayonet 121 of the liquid storage member 12.

[0065] When assembling the heating assembly 30, the sheet-shaped composite liquid guiding cotton raw material may be first wrapped around the heating element 33 to form the first liquid guiding portion 315. Then, the first liquid guiding portion 315 wrapped with the heating element 33 is inserted downward into the heating base 32 through the upper end opening of the heating base 32. The second end 3152 of the first liquid guiding portion 315 extends radially outward from the slot 3211 to form a first extension portion 317. The first end 3151 of the first liquid guiding portion 315 passes through the slot 3211 and is wound around the outside of the heating base 32 to form the second liquid guiding portion 316. Then, the other end of the second liquid guiding portion 316 is attached to the first extension portion 317 to form a second extension portion 318. Finally, the liquid storage member 12 is wrapped around the heating assembly 30, and the joined first extension portion 317 and second extension portion 318 are snapped into the bayonet 121 of the liquid storage member 12.

[0066] In this embodiment, the second liquid guiding portion 316, the first extension portion 317, and the second extension portion 318 of the composite liquid guiding cotton 31 are all in contact with the liquid storage member 12, thereby greatly increasing the contact area between the composite liquid guiding cotton 31 and the liquid storage member 12, and significantly improving the liquid absorption speed of the composite liquid guiding cotton 31.

[0067] Another example is Figures 3-4As shown, the base 20 and the end cap 50 respectively cover both ends of the liquid storage space 110, and they can be made of elastic materials such as silica gel respectively, so as to facilitate sealing both ends of the liquid storage space 110 and reducing liquid leakage. Specifically, the base 20 can be embedded in the lower opening of the liquid storage shell 11, that is, the opening of the liquid storage shell 11 at one end close to the battery 90. The base 20 can be used to support the liquid storage member 12 and the heating component 30. An air guide hole 21 communicating with the atomization chamber 330 can be formed longitudinally on the base 20. The end cap 50 can be embedded in the upper opening of the liquid storage shell 11, that is, the opening of the liquid storage shell 11 at one end close to the nozzle assembly 70. An air vent hole 51 communicating with the upper end of the air flow channel 41 can be formed longitudinally on the end cap 50.

[0068] In some embodiments, the end cap 50 may include an end cap body 52 and a nested portion 53 extending downward from the lower end surface of the end cap body 52. The end cap body 52 and the nested portion 53 can be coaxially arranged. The end cap body 52 is embedded in the upper opening of the liquid storage shell 11, and the outer wall surface of the end cap body 52 can be sealingly fitted with the inner wall surface of the liquid storage shell 11 to avoid liquid leakage. The upper end surface of the end cap body 52 forms a support surface 520 for supporting the liquid absorption member 60. An annular cavity 122 can be formed between the lower end surface of the end cap body 52 and the upper end surface of the liquid storage member 12, which can prevent the end cap body 52 from squeezing the liquid storage member 12 to cause liquid leakage. In other embodiments, the lower end surface of the end cap body 52 may also be in contact with the upper end surface of the liquid storage member 12.

[0069] The nested portion 53 is inserted downward into the air flow channel 41 for assembly. In this embodiment, the outer wall surface of the nested portion 53 is sealingly fitted with the inner wall surface of the ventilation pipe 40, and the lower end surface of the end cap body 52 is sealingly fitted with the upper end surface of the ventilation pipe 40. The outer diameter of the lower end of the nested portion 53 can gradually increase from bottom to top to form a guiding inclined surface that is conducive to inserting into the air flow channel 41. By reducing the length of the nested portion 53 extending into the air flow channel 41, the length of the hole wall of the air vent hole 51 adsorbing the atomized gas can be reduced, the loss of the aroma and sweetness of the atomized gas can be reduced, and the accumulation of condensate in the air vent hole 51 can be reduced. In some embodiments, the length of the nested portion 53 extending into the air flow channel 41 is less than or equal to 6.5 mm.

[0070] The liquid absorption member 60 is supported on the support surface 520 of the end cap 50 and is in contact with the support surface 520, and is used to absorb the condensate accumulated in the air vent hole 51, so as to prevent the condensate accumulated in the air vent hole 51 from being sucked into the user's mouth. An air outlet hole 61 communicating with the air vent hole 51 can be formed longitudinally on the liquid absorption member 60. The liquid absorption member 60 is usually a liquid absorption cotton, so as to be able to absorb and store more condensate.

[0071] Such as Figure 7As shown, at least one first diversion groove 521 may be provided on the support surface 520. The first diversion groove 521 has a first end 5211 and a second end 5212 opposite to the first end 5211. The first end 5211 of the first diversion groove 521 is communicated with the ventilation hole 51, and the second end 5212 of the first diversion groove 521 extends in a direction away from the ventilation hole 51. The condensate at the ventilation hole 51 can be drained through the first diversion groove 521 and then absorbed by the liquid absorbent member 60 in contact with the first diversion groove 521, thereby accelerating the liquid absorption speed of the liquid absorbent member 60. Preferably, the number of the first diversion grooves 521 is more than two, and the second ends 5212 of the first diversion grooves 521 at least extend to be communicated with the outer edge of the bottom surface of the liquid absorbent member 60, so as to drain the condensate at the ventilation hole 51 to the entire bottom surface of the liquid absorbent member 60.

[0072] The shape of the first diversion groove 521 is not limited. For example, it can be a straight groove or a curved groove. In this embodiment, the first diversion groove 521 is a straight groove, and the first diversion groove 521 can extend along the radial direction of the support surface 520. The longest length of the first diversion groove 521 is greater than or equal to the radius of the liquid absorbent member 60. Preferably, the number of the first diversion grooves 521 is proportional to the cross-sectional area of the ventilation hole 51, that is, the larger the cross-sectional area of the ventilation hole 51 is, the more the first diversion grooves 521 are needed, and the better the drainage effect is. The two or more first diversion grooves 521 can be evenly distributed along the circumferential direction of the support surface 520, which is convenient for evenly and quickly draining the condensate at the ventilation hole 51 to the entire bottom surface of the liquid absorbent member 60.

[0073] Furthermore, at least one second diversion groove 522 communicated with the at least one first diversion groove 521 may be provided on the support surface 520. The condensate at the ventilation hole 51 is drained to the first diversion groove 521 and the second diversion groove 522 communicated with the first diversion groove 521, and then absorbed by the liquid absorbent member 60 in contact with the first diversion groove 521 and the second diversion groove 522. In this embodiment, the second diversion groove 522 is in a circular ring shape, and each circular ring-shaped second diversion groove 522 is communicated with the two or more first diversion grooves 521. Preferably, the number of the second diversion grooves 522 can be two or more. When the number of the second diversion grooves 522 is multiple, the distance between every two adjacent second diversion grooves 522 among the multiple second diversion grooves 522 gradually decreases in a direction away from the ventilation hole 51, which is beneficial to making the condensate at the ventilation hole 51 spread faster to the periphery and be absorbed by the liquid absorbent member 60. In this embodiment, the maximum radius of the at least two second diversion grooves 522 is equal to the longest length of the first diversion groove 521. It can be understood that in other embodiments, only the first diversion groove 521 may be provided on the support surface 520, and the second diversion groove 522 may not be provided.

[0074] Again, such as Figure 3As shown, the nozzle assembly 70 includes a nozzle 71. The nozzle 71 is disposed at the upper end of the liquid storage housing 11, and an air suction channel 710 communicating with the air outlet hole 61 is formed longitudinally thereon. The upper part of the liquid storage housing 11, the end cap 50, and the liquid suction member 60 can all be received in the lower part of the nozzle 71.

[0075] Herein, the air guide hole 21, the atomization chamber 330, the air flow channel 41, the ventilation hole 51, the air outlet hole 61, and the air suction channel 710 are sequentially communicated from bottom to top to form a mist delivery channel 130. Among them, the air guide hole 21 forms an intake channel for introducing external air of the mist delivery channel 130, and the air flow channel 41, the ventilation hole 51, the air outlet hole 61, and the air suction channel 710 together form an outlet channel for outputting the atomized gas of the mist delivery channel 130. External air enters from the intake channel, flows upward to the atomization chamber 330 and mixes with the aerosol generated after the heating assembly 30 heats the atomized liquid. The generated atomized gas is then output via the outlet channel and inhaled by the user.

[0076] In some embodiments, the nozzle assembly 70 may further include a sealing plug 72. The sealing plug 72 can be made of an elastic material such as silica gel. The sealing plug 72 is detachably plugged at the upper end of the air suction channel 710 and can be used to seal the air suction channel 710 when the atomizer 100 is not in use, so as to prevent dust and the like from entering the air suction channel 710.

[0077] Figures 8-9 The atomizer 100 in the second embodiment of the present invention is shown. The main difference from the first embodiment is that the liquid storage member 12 in this embodiment is communicated with the outside through a pressure balance channel 54. When the ambient temperature rises, the air heated and expanded inside the atomizer 100 can be discharged to the outside of the atomizer 100 through the pressure balance channel 54, avoiding excessive extrusion of the atomized liquid, thereby solving the problem of liquid leakage at high temperatures.

[0078] As described above, in this embodiment, the air guide hole 21, the atomization chamber 330, the air flow channel 41, the ventilation hole 51, the air outlet hole 61, and the air suction channel 710 are sequentially communicated from bottom to top to form a mist delivery channel 130. The pressure balance channel 54 can be communicated with the mist delivery channel 130 and then with the outside. Preferably, the pressure balance channel 54 can be formed by adopting an interference fit between the end cap 50 and the ventilation pipe 40, so that the liquid storage member 12 is communicated with the air flow channel 41 and the ventilation hole 51 through the pressure balance channel 54, and further the liquid storage member 12 is communicated with the outside. By adopting the method of reserving an interference fit gap between the end cap 50 and the ventilation pipe 40 to form the pressure balance channel 54, the design is simple and operations such as opening holes and slots on the components can be avoided. In some embodiments, the interference fit gap between the end cap 50 and the ventilation pipe 40 can be 0 - 0.1 mm.

[0079] Specifically, in this embodiment, the end cap 50 may include an end cap body 52 and a nested portion 53 that extends downward from the end cap body 52 and extends into the air flow channel 41. The ventilation hole 51 penetrates through the end cap body 52 and the nested portion 53 longitudinally, and may be coaxially arranged with the end cap body 52 and the nested portion 53. An annular cavity 122 may be formed between the lower end surface of the end cap body 52 and the upper end surface of the liquid storage member 12. A groove 523 is recessed on the bottom surface of the end cap body 52, and the groove 523 may be coaxially arranged with the end cap body 52. The nested portion 53 may extend downward from the bottom surface of the groove 523.

[0080] The upper end of the ventilation pipe 40 may be received in the groove 523. There is a first fitting gap between the inner wall surface of the groove 523 and the outer wall surface of the ventilation pipe 40, and this first fitting gap forms a first channel 541 that communicates with the cavity 122. There is a second fitting gap between the bottom surface of the groove 523 and the upper end surface of the ventilation pipe 40, and this second fitting gap forms a second channel 542 that communicates with the first channel 541. There is a third fitting gap between the outer wall surface of the nested portion 53 and the inner wall surface of the ventilation pipe 40, and this third fitting gap forms a third channel 543 that communicates with the second channel 542. The first channel 541, the second channel 542, and the third channel 543 are sequentially communicated to form a pressure balance channel 54 that connects the cavity 122 and the air flow channel 41. When the ambient temperature rises, the air heated and expanded in the cavity 122 and the air heated and expanded in the liquid storage member 12 are sequentially discharged into the air flow channel 41 through the first channel 541, the second channel 542, and the third channel 543, and then discharged to the outside of the atomizer 100 through the mist delivery channel 130.

[0081] Figure 10 The atomizer 100 in the third embodiment of the present invention is shown. The main difference from the second embodiment is that in this embodiment, the end cap 50 only includes the end cap body 52. Specifically, the ventilation hole 51 penetrates through the end cap body 52 longitudinally, and the upper end of the ventilation pipe 40 extends into the ventilation hole 51 and communicates with the ventilation hole 51. There is a fitting gap between the outer wall surface of the ventilation pipe 40 and the hole wall of the ventilation hole 51, and this fitting gap forms a pressure balance channel 54 that connects the cavity 122 and the ventilation hole 51.

[0082] Figure 11The atomizer 100 in the fourth embodiment of the present invention is shown. The main difference from the second embodiment is that in this embodiment, the end cap 50 only includes an end cap body 52. Specifically, the ventilation hole 51 extends downward from the upper end surface of the end cap body 52. A groove 523 communicating with the ventilation hole 51 is recessed on the bottom surface of the end cap body 52, and the outer diameter of the groove 523 is larger than that of the ventilation hole 51. The upper end of the ventilation pipe 40 can be received in the groove 523. There is a first fitting gap between the inner wall surface 5231 of the groove 523 and the outer wall surface of the ventilation pipe 40, and this first fitting gap forms a first channel 541 communicating with the cavity 122. There is a second fitting gap between the bottom surface 5232 of the groove 523 and the upper end surface of the ventilation pipe 40, and this second fitting gap forms a second channel 542 communicating with the first channel 541. The first channel 541 and the second channel 542 are sequentially communicated to form a pressure balance channel 54 that communicates the cavity 122 with the air flow channel 41 and the ventilation hole 51.

[0083] Figure 12 The atomizer 100 in the fifth embodiment of the present invention is shown. The main difference from the second embodiment is that in this embodiment, the lower end surface of the end cap body 52 contacts the upper end surface of the liquid storage member 12, that is, no cavity 122 is formed between the lower end surface of the end cap body 52 and the upper end surface of the liquid storage member 12. Correspondingly, the first channel 541 of the pressure balance channel 54 in this embodiment communicates with the liquid storage member 12. When the ambient temperature rises, the air heated and expanded in the liquid storage member 12 is discharged into the air flow channel 41 through the first channel 541, the second channel 542, and the third channel 543 in sequence, and then is discharged to the outside of the atomizer 100 through the mist delivery channel 130.
