[0028] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various embodiments. Meanwhile, the steps or actions in the method description can also be sequentially replaced or adjusted in a manner that is obvious to the person skilled in the art. Therefore, the various sequences in the specification and drawings are only for the purpose of clearly describing a certain embodiment, and do not mean that the sequence is necessary, unless otherwise stated that a certain sequence must be followed.

[0029] The serial numbers of components in this paper, such as "first", "second", etc., are only used to distinguish the described objects, and have no sequence or technical meaning. The "connection" and "coupling" in the present application include direct and indirect connection (coupling) unless otherwise specified.

[0030] Please refer to Figure 1 In some embodiments, an atomization device is provided, which includes an atomizer 1 and a power supply unit 2. The atomizer 1 and the power supply unit 2 can be detachably electrically connected. Specifically, the power supply unit 2 has an accommodation cavity 20 with an opening facing upward, the shape of the accommodation cavity 20 is matched with the shape of the atomizer 1, and the atomizer 1 can be inserted into the accommodation cavity 20 or pulled out of the accommodation cavity 20. In some embodiments, the power supply unit 2 can include a battery (not shown) and a control unit (not shown), etc. When the atomizer 1 is inserted into the accommodation cavity 20, an electrical connection is formed between the atomizer 1 and the battery, and the battery can supply power to the atomizer 1. The control unit can include a circuit board and other components, and the control unit and the battery are mechanically and / or electrically connected together, which can control the atomization switch, atomization power, etc. of the atomizer 1.

[0031] Please refer to Figure 2In some embodiments, a cartomizer 1 is provided, which is used in combination with a power supply unit 2, and the two are detachably electrically connected. The cartomizer 1 comprises a housing 10, a liquid storage 12 and a first seal 11. The housing 10 defines a cavity. The liquid storage 12 is arranged in the cavity. The liquid storage 12 can be a liquid storage cotton or other porous material, which is mainly used for storing liquid e-liquid. When the e-liquid is consumed, the liquid storage 12 can be replaced with a new one.

[0032] The first seal 11 is arranged in the cavity and located on one side of the liquid storage 12 (on the upper side of the liquid storage 12). Figure 2 The first seal 11 is at least partially in sealing contact with the housing 10. Referring to Figure 2 , the circumferential surface of the first seal 11 is in contact with the housing 10, and the two are in sealing contact along the circumferential surface of the first seal 11. For example, the first seal 11 is made of plastic or sealing silicone, and the two can be in sealing contact through tight fit, interference fit, etc.

[0033] When the cartomizer 1 is in operation, the user is inhaling, or the temperature changes, the pressure in the cavity will change accordingly. When the pressure in the cavity changes, the air and the liquid e-liquid in the cavity will expand, and the expansion speed of the air is greater than that of the liquid e-liquid, so that the liquid e-liquid is extruded, resulting in the phenomenon that the e-liquid leaks from the bottom of the cavity or from the atomizer 16. In some embodiments, the cartomizer 1 is a large-capacity cartomizer 1, the volume of the cavity is 15ml, and the maximum filling amount of the liquid storage 12 is 5-15ml. The large-capacity liquid storage 12 can store more e-liquid in advance, thereby reducing the frequency of replacing the liquid storage 12. However, the large-capacity liquid storage 12 is also more likely to cause the above-mentioned leakage phenomenon due to pressure changes. In order to reduce the risk of leakage of the cartomizer 1, there is a first gap 13 between the surfaces of at least part of the first seal 11 and the liquid storage 12 facing each other. The first gap provides a buffer space for gas expansion, reduces the extrusion effect of gas pressure change on liquid, thereby preventing the cartomizer 1 from leaking.

[0034] In order to reduce the risk of leakage, the recommended filling amount is not more than 12ml under the condition that the volume of the cavity is 15ml, for example, it can be implemented as 9ml or 10ml.

[0035] In one embodiment, referring to Figure 3 , the height of the first gap 13 can be 2mm, that is, the distance between the top surface of the liquid storage 12 and the bottom surface of the first seal 11 can be 2mm; the height of the first gap 13 can also be set to any value within the range of 1-3mm, and the purpose of the first gap 13 is to reserve a gas expansion space.

[0036] In some embodiments, the surfaces of the first seal 11 and the reservoir 12 facing each other (opposing surfaces) may be completely spaced apart, that is, the first seal 11 and the reservoir 12 are not in contact at all (not shown), thereby defining the first gap 13.

[0037] Alternatively, in other embodiments, a portion of the first seal 11 and the liquid reservoir 12 may be spaced apart from each other to define a first gap 13, while another portion of the first seal 11 contacts the liquid reservoir 12; that is, Figure 3 The protrusion 111 shown is in contact with the liquid reservoir 12.

[0038] Or, such as Figure 9 As shown, in another embodiment, another part of the first seal 11 may not be in contact with the liquid reservoir 12. There is also a second gap 132 between the other part of the first seal 11 and the surface of the liquid reservoir 12 facing each other. The height (longitudinal dimension) of the second gap 132 is smaller than the height (longitudinal dimension) of the first gap 13.

[0039] In related technologies, when the atomizer 1 is designed with a capacity of 2-3ml, the risk of leakage is relatively low. However, since this type of atomizer 1 is not reusable, it means that consumers need to replace the atomizer 1 every time they use 2-3ml of atomizing matrix. Experimental verification shows that the atomizer 1 in the above embodiment can meet the liquid injection volume of 5-13ml, significantly improving the service life of a single atomizer 1 and reducing the user cost.

[0040] like Figures 2 to 5 As shown, in some embodiments, the atomizer 1 further includes an atomizing tube 14, which is also disposed within the cavity, and the liquid reservoir 12 and the atomizing tube 14 are disposed on the same side of the first seal 11. Figure 2 The lower side of the first seal 11). The liquid reservoir 12 surrounds the outer periphery of the atomizing tube 14. The end of the atomizing tube 14 near the first seal 11 ( Figure 2 The upper end of the atomizing tube 14 extends into the first gap 13. Furthermore, a third gap 15 is formed between the end of the atomizing tube 14 near the first seal 11 and the sealing body 110. The end of the atomizing tube 14 away from the first seal 11 is connected to the atmosphere outside the atomizer 1. Thus, the first gap 13, the third gap 15, the atomizing tube 14, and the atmosphere are sequentially connected. The air within the first gap 13 is connected to the external atmospheric environment of the atomizer 1 through the third gap 15 and the atomizing tube 14, which can balance the pressure changes within the cavity, promote gas-liquid balance, and thereby reduce the risk of atomization matrix leakage.

[0041] Please refer to the following: Figure 2 and Figure 3In some embodiments, the first seal 11 includes a seal body 110 and a protrusion 111. The seal body 110 is sealed with the housing 10. The protrusion 111 is disposed on a surface of the seal body 110 facing the liquid reservoir 12 (see the lower surface of the seal body 110 in the figures). The cross-sectional area of the protrusion 111 is smaller than that of the seal body 110. The cross-sectional area refers to the lateral direction as indicated in the orientation in Figure 2 In the longitudinal direction, a first gap 13 is formed between the surfaces of the seal body 110 and the liquid reservoir 12 facing each other. The protrusion 111 is in contact with the surface of the liquid reservoir 12 facing it. Alternatively, as shown in Figure 9 In other embodiments, a second gap 132 is formed between the protrusion 111 and the surface of the liquid reservoir 12 facing it, and the height (longitudinal dimension) of the second gap 132 is smaller than that of the first gap 13.

[0042] In the embodiments shown in Figure 2 , the surface of the liquid reservoir 12 facing the seal body 110 (see the upper surface of the liquid reservoir 12 in the figures) is in contact with the protrusion 111. Thus, the protrusion 111 can also support the liquid reservoir 12 and limit the position of the liquid reservoir 12 in the cavity. Of course, in other embodiments, the surface of the liquid reservoir 12 facing the seal body 110 can not be in contact with the protrusion 111, but a gap is formed between the surface of the liquid reservoir 12 and the protrusion 111.

[0043] As shown in Figures 6 to 8 , in some embodiments, the protrusion 111 includes at least two bosses 1110, and each boss 1110 is spaced apart from each other. In the embodiments shown in Figure 8 , there are four bosses 1110, and the lateral dimension and the longitudinal dimension of each boss 1110 are equal. Each boss 1110 can be in contact with the upper surface of the liquid reservoir 12 or not. Further, the spacing between each adjacent boss 1110 can be equal, so that the bosses 1110 are evenly distributed on the lower surface of the seal body 110.

[0044] Further, as shown in Figures 2 to 5As shown, in some embodiments, the atomizer 1 further comprises an atomizing core 16. The atomizing core 16 is arranged inside the tube cavity enclosed by the atomizing tube 14, and the atomizing tube 14 is provided with a liquid inlet hole (not shown) through which the atomizing core 16 is in liquid communication with the liquid storage member 12 wrapped around the periphery of the atomizing tube 14. The atomizing substrate stored in the liquid storage member 12 can be in contact with the atomizing core 16 via the liquid inlet hole. When the atomizer 1 is inserted into the accommodation cavity 20, the atomizing core 16 is mechanically and / or electrically connected with the battery, and the battery can supply power to the atomizing core 16. The atomizing core 16 can generate heat in the powered state to heat and atomize the atomizing substrate. The aerosol generated by the heat and atomization flows upward (towards the first sealing member 11) through the atomizing tube 14, and finally overflows out of the atomizer 1 for the user to smoke.

[0045] Further, as Figures 2 to 5 shown, in some embodiments, the housing 10 comprises a shell 101 and a mouthpiece airway 102 connected together to define a cavity. The end of the mouthpiece airway 102 away from the shell 101 extends longitudinally downward towards the inside of the cavity. The end of the shell 101 and the mouthpiece airway 102 connected together extends longitudinally upward away from the cavity to form a mouthpiece 19, which is a tubular structure with a hole in the middle. The end of the mouthpiece 19 away from the mouthpiece airway 102 (i.e. the upper end of the mouthpiece 19) is in communication with the atmosphere outside the atomizer 1. Figure 2 The mouthpiece airway 102 is also a tubular structure with a hole in the middle. The sealing body 110 is sealingly connected to the shell 101 and the mouthpiece airway 102, respectively. Moreover, the sealing body 110 is provided with a central through hole 1101 in communication with the mouthpiece airway 102. Thus, in the longitudinal direction from top to bottom, the mouthpiece 19, the mouthpiece airway 102, the central through hole 1101 on the sealing body 110 and the atomizing tube 14 are sequentially in communication with each other, and the aerosol generated by the atomizing core 16 heating and atomizing the atomizing substrate inside the atomizing tube 14 flows sequentially from bottom to top through the central through hole 1101 on the sealing body 110, the mouthpiece airway 102 and the mouthpiece 19, and then overflows out of the atomizer 1 for the user to smoke.

[0046] As Figure 2 and Figure 3As shown, in some embodiments, the housing 101 comprises a first portion 1011 and a second portion 1012. The first portion 1011 is connected with the mouthpiece airway 102 and forms the mouthpiece 19. The second portion 1012 surrounds the outer periphery of the liquid storage piece 12, and the outer periphery of the liquid storage piece 12 is in contact with the second portion 1012. The cross-sectional width of the first portion 1011 is smaller than the cross-sectional width of the second portion 1012. The cross-sectional width refers to the lateral width of the cross-section. The sealing body 110 is in sealing contact with the first portion 1011, and the sealing body 110 is not in contact with the second portion 1012. The protrusion 111 is also not in contact with the second portion 1012, and the protrusion 111 is spaced apart from the second portion 1012. That is, a lateral space is formed between the protrusion 111 and the second portion 1012. In this way, on the one hand, the fourth gap 17 is formed between the first portion 1011 and the surface of the liquid storage piece 12 facing the first seal 11 (referring to the upper surface in the figure), and the fourth gap 17 and the first gap 13 together reserve a part of the space for the expansion of air, thereby further reducing the risk of leakage of the atomized substrate; on the other hand, the second portion 1012 serves as one of the boundaries of the cavity, and has a relatively large cross-sectional width, which expands the lateral width of the cavity, and the outer periphery of the liquid storage piece 12 is in contact with the second portion 1012, which also expands the lateral design width of the liquid storage piece 12. The volume of the liquid storage piece 12 is increased, which can provide more flow space for the liquid atomized substrate stored therein, and delay the speed of leakage of the liquid atomized substrate.

[0047] Further, in order to reduce the risk of leakage of the liquid atomized substrate, the oil filling rate of the liquid storage piece 12 in the cavity can also be set to 60% to 70%. It should be noted that the oil filling rate p is equal to the ratio of the actual liquid storage amount p1 of the liquid storage piece 12 in the cavity to the maximum liquid storage amount p2 before the atomizer 1 is first used (that is, before the atomized substrate stored in the liquid storage piece 12 starts to be consumed). That is, p = p1 / p2. For example, when the maximum liquid storage amount (or the limit liquid storage amount) p2 of the liquid storage piece 12 is designed to be 10 ml, only 6 to 7 ml of liquid atomized substrate is filled into the liquid storage piece 12. In this way, the liquid storage amount of the liquid storage piece 12 in the cavity is less than the designed maximum liquid storage amount, which can further reduce the risk of leakage of the liquid atomized substrate.

[0048] For example, Figure 2 , Figure 4 and Figure 5As shown, in some embodiments, the atomizer 1 further includes a second seal 18. The second seal 18 is disposed at the opening and is sealed to the second portion 1012, with the liquid reservoir 12 located between the first seal 11 and the second seal 18. The surfaces of the first seal 11 and the second seal 18 facing each other, together with the outer circumference of the atomizing tube 14, define an annular liquid reservoir in which the liquid reservoir 12 is disposed. Specifically, the opening is formed at the end of the second portion 1012 of the housing 101 away from the first portion 1011. The second seal 18 is sealed to the second portion 1012 of the housing 101. The housing 101 also includes a bottom shell 1013, which is disposed on the side of the second seal 18 away from the liquid reservoir 12 (refer to the lower side of the second seal 18 in the figures) and connected to the second portion 1012, thereby covering the side of the second seal 18 away from the liquid reservoir 12. The bottom shell 1013, the second part 1012 and the first part 1011 of the shell 101, and the mouthpiece air passage 102 together define a cavity. The first seal 11, the liquid storage component 12, the atomizing tube 14, and the second seal 18 are all disposed within this cavity.

[0049] like Figure 2 , Figures 6 to 8 As shown, in some embodiments, the first seal 11 further includes a liquid-absorbing member 112. A mounting groove 1102 is recessed on the surface of the sealing body 110 facing the nozzle air passage 102 (refer to the upper surface of the sealing body 110 in each figure). This mounting groove 1102 does not penetrate the surface of the sealing body 110 facing the liquid reservoir 12 (refer to the lower surface of the sealing body 110 in each figure). The mounting groove 1102 is located around the central through hole 1101. The liquid-absorbing member 112 is disposed within the mounting groove 1102 and also has a central through hole that communicates with the central through hole 1101 of the sealing body 110. The liquid-absorbing member 112 is in direct contact with the nozzle air passage 102, while the sealing body 110 is indirectly sealed to the nozzle air passage 102 through the liquid-absorbing member 112. The liquid-absorbing member 112 can be used to absorb liquid atomizing matrix overflowing from the sealing body 110 and to absorb condensate, thereby further reducing the risk of liquid atomizing matrix leakage.

[0050] like Figure 2 , Figure 4 and Figure 5As shown, in some embodiments, the first part 1011, the second part 1012 and the mouthpiece airway 102 of the shell 101 are integrally formed, and the bottom cover is detachably connected with the second part 1012. When the atomizer 1 is installed, first, a first combination of the first part 1011, the second part 1012 and the mouthpiece airway 102 is prepared, then the first seal 11 is installed in the space enclosed by the first combination, and the liquid suction member 112 on the upper side of the seal main body 110 is abutted against the mouthpiece airway 102, and the outer periphery of the seal main body 110 is tightly fitted with the first part 1011 of the shell 101. Then, the liquid storage member 12 is surrounded by the outer periphery of the atomization tube 14, the second combination of the liquid storage member 12 and the atomization tube 14 is installed in the space enclosed by the first combination, the protruding part 111 of the first seal 11 is abutted against the upper surface of the liquid storage member 12, the first gap 13 is formed between the lower surface of the seal main body 110 and the upper surface of the liquid storage member 12, and the third gap 15 is formed between the upper end of the atomization tube 14 and the lower surface of the seal main body 110. Then, the second seal 18 is continuously installed in the space enclosed by the first combination, the second seal 18 is abutted against the lower surface of the liquid storage member 12, and the outer periphery of the second seal 18 is tightly fitted with the second part 1012 of the shell 101. Finally, the bottom shell 1013 is covered on the lower side of the second seal 18, and the bottom shell 1013 is connected with the second part 1012 of the shell 101, and the atomizer 1 is assembled.

[0051] The above application of specific examples to the utility model is described, just to help understand the utility model, and not to limit the utility model. For the skilled in the art to which the utility model belongs, according to the idea of the utility model, a number of simple deductions, deformation or replacement can be made.
