Description

Technical Field

[0001] The present application belongs to the technical field of electronic cigarettes, and specifically relates to an electronic cigarette cartridge and an electronic cigarette. Background Art

[0002] At present, the oil channel and air channel of the cotton core atomizer structure in electronic cigarettes are designed to be separated, but the oil channel and the air channel must be well sealed so that the e-liquid is not easy to leak into the air channel and consumers are not easy to inhale the e-liquid during the smoking process.

[0003] In the prior art, since the oil channel and the air channel need to be sealed at the joint, the ventilation of the entire cigarette cartridge depends entirely on the ventilation of the cotton core itself. When the ventilation channel of the cotton core is blocked, it is difficult for external air to enter the outer shell liquid storage tank after atomization. At this time, the outer shell liquid storage tank is in a negative pressure state, and the smoke oil is difficult to completely wet the atomization surface under the action of negative pressure. When the ventilation channel of the cotton core is too unobstructed, it is very easy for external air to enter the outer shell liquid storage tank after atomization. At this time, the outer shell liquid storage tank is in a small pressure difference with the outside world, and the smoke oil penetrates too quickly. Too much smoke oil accumulates on the cotton core, and the cotton core atomizer is not atomized in time.

[0004] However, the difficulty of the e-liquid in wetting the atomizing surface will result in low smoke volume, poor taste, and a burnt smell when inhaling. Or the cotton core will burn dry, causing the plastic to melt and produce odor and other problems. The rapid penetration of the e-liquid will cause too much e-liquid to accumulate on the cotton core, causing oil frying and e-liquid entering the mouth. The above problems will bring a bad smoking experience to users. Utility Model Content

[0005] The purpose of the embodiments of the present application is to provide an electronic cigarette cartridge and an electronic cigarette, which can solve the problem in the prior art that the electronic cigarette cartridge is difficult to control the speed of smoke oil penetration due to ventilation problems, thereby affecting the user's smoking experience.

[0006] In order to solve the above technical problems, this application is implemented as follows:

[0007] In a first aspect, an embodiment of the present application provides an electronic cigarette cartridge, comprising: a shell, the shell being provided with an airway wall; a bracket, the bracket comprising a connecting end, the connecting end being fixedly connected to the airway wall, the airway wall and the bracket dividing the inner cavity of the shell into a smoke channel and a liquid storage chamber; the airway wall or the connecting end being provided with an air vent, the air vent connecting the smoke channel and the liquid storage chamber; an adjusting member, an openable and closable adjusting member being provided at the position of the air vent, the adjusting member being provided at one end of the air vent facing the liquid storage chamber.

[0008] In an embodiment of the present application, the shell can be enclosed to form an inner cavity, and the inner cavity can be used to hold a fluid. The shell is provided with an airway wall, and the airway wall is arranged in the inner cavity. The bracket is also arranged in the inner cavity, and the connecting end of the bracket is connected to the airway wall. The arrangement of the airway wall and the bracket separates the inner cavity of the shell into a smoke channel and a liquid storage cavity, so that the smoke channel and the liquid storage cavity are independent of each other. In the electronic cigarette cartridge, the liquid storage cavity can be used to hold the smoke oil, and the smoke oil can form smoke after atomization. The smoke and the outside air are mixed to form an aerosol. The setting of the smoke channel can be used to realize the circulation of smoke, and can also be used to realize the circulation of outside air, and can also be used to realize the circulation of aerosol. Further, the smoke channel can include an air inlet and an air outlet. During the actual use of the user, the outside air enters the smoke channel through the air inlet, and the outside gas and the smoke are mixed to form an aerosol. The aerosol then flows through the smoke channel to the air outlet and finally flows to the user and is inhaled by the user. The airway wall or the connecting end is provided with a vent hole, and the vent hole connects the smoke channel and the liquid storage chamber, that is, the setting of the vent hole connects the outside atmosphere and the liquid storage chamber, so that the airflow in the liquid storage chamber and the outside atmosphere can be connected, thereby achieving the pressure balance between the liquid storage chamber and the outside atmosphere. The adjusting member is arranged at one end of the vent hole facing the liquid storage chamber, and the adjusting member can be opened and closed. It can be understood that the air intake rate of the gas entering the liquid storage chamber from the vent hole can be adjusted by the cooperation of the vent hole and the adjusting member, thereby balancing the pressure between the liquid storage chamber and the smoke channel. Specifically, when the pressure in the smoke channel is greater than the pressure in the liquid storage chamber, since the adjusting member is arranged at one end of the vent hole facing the liquid storage chamber, the adjusting member opens the vent hole under the pressure difference between the two, and the aerosol in the smoke channel enters the liquid storage chamber; when the pressure in the smoke channel is less than the pressure in the liquid storage chamber, the adjusting member covers the vent hole under the pressure difference between the two. In the embodiment of the present application, the above-mentioned setting achieves a balanced pressure difference between the liquid storage chamber and the smoke channel by controlling the aerosol entering the liquid storage chamber from the smoke channel, so that the smoke oil in the liquid storage chamber penetrates into the atomization component at a uniform speed to achieve atomization, which has the beneficial effect of avoiding excessive atomized smoke oil causing oil explosion and too little smoke oil inlet or smoke oil causing insufficient smoke volume, thereby affecting the user experience.

By providing mutually cooperating vents and adjusting parts on the electronic cigarette cartridge, the air intake rate of the gas entering the liquid storage chamber from the vents can be adjusted, thereby balancing the pressure between the liquid storage chamber and the smoke channel.

In the embodiment of the present application, the above-mentioned setting achieves a balanced pressure difference between the liquid storage chamber and the smoke channel by controlling the aerosol entering the liquid storage chamber from the smoke channel, so that the smoke oil in the liquid storage chamber penetrates into the atomization component at a uniform speed to achieve atomization, thereby avoiding the problem of excessive atomized smoke oil causing oil explosion and insufficient smoke volume due to the inlet of smoke oil or too little smoke oil, which leads to poor user experience, and has the beneficial effect of improving user experience.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0030] The electronic cigarette cartridge and the electronic cigarette provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0031] Previous electronic cigarette cartridges did not have a separate ventilation structure. The design that simply relied on the ventilation of the cotton core in the atomizer assembly was very difficult to control the speed of smoke oil penetration and difficult to find a suitable balance point. It was easy to cause dry burning of the core or oil explosion. Based on the previous electronic cigarette cartridges without independent ventilation structure, this application provides an independent structure that can realize ventilation, which can better control the pressure difference between the liquid storage tank and the outside world and improve the user experience.

[0032] See also Figures 1 to 6The embodiment of the present application provides an electronic cigarette cartridge, including: a shell 10, the shell 10 is provided with an airway wall 11; a bracket 20, the bracket 20 includes a connecting end 21, the connecting end 21 is fixedly connected to the airway wall 11, the airway wall 11 and the bracket 20 separate the inner cavity of the shell 10 into a smoke channel 12 and a liquid storage chamber 13; the airway wall 11 or the connecting end 21 is provided with a vent 30, the vent 30 connects the smoke channel 12 and the liquid storage chamber 13; an adjusting member 40, an openable and closable adjusting member 40 is provided at the position of the vent 30, and the adjusting member 40 is arranged at one end of the vent 30 facing the liquid storage chamber 13.

[0033] In the embodiment of the present application, the shell 10 can be enclosed to form an inner cavity, which can be used to hold a fluid. The shell 10 is provided with an airway wall 11, which is arranged in the inner cavity. The bracket 20 is also arranged in the inner cavity, and the connecting end 21 of the bracket 20 is connected to the airway wall 11. The arrangement of the airway wall 11 and the bracket 20 separates the inner cavity of the shell 10 into a smoke channel 12 and a liquid storage chamber 13, so that the smoke channel 12 and the liquid storage chamber 13 are independent of each other. In the electronic cigarette cartridge, the liquid storage chamber 13 can be used to hold smoke oil, which can form smoke after atomization, and the smoke and the outside air are mixed to form an aerosol. The arrangement of the smoke channel 12 can be used to realize smoke circulation, can also be used to realize outside air circulation, and can also be used to realize aerosol circulation. Further, the smoke channel 12 may include an air inlet and an air outlet. During actual use by the user, the outside air enters the smoke channel 12 through the air inlet, and the outside gas and smoke are mixed to form an aerosol. The aerosol then flows through the smoke channel 12 to the air outlet and finally flows to the user and is inhaled by the user. The airway wall 11 or the connecting end 21 is provided with a vent 30, and the vent 30 connects the smoke channel 12 and the liquid storage chamber 13. In other words, the setting of the vent 30 connects the outside atmosphere and the liquid storage chamber 13, so that the air flow in the liquid storage chamber 13 and the outside atmosphere can be connected to achieve the balance of air pressure between the liquid storage chamber 13 and the outside atmosphere. The adjusting member 40 is arranged at one end of the vent 30 facing the liquid storage chamber 13, and the adjusting member 40 can be opened and closed. It can be understood that the air intake rate of the gas entering the liquid storage chamber 13 from the vent 30 can be adjusted by the cooperation of the vent 30 and the adjusting member 40, so as to balance the pressure between the liquid storage chamber 13 and the smoke channel 12. Specifically, when the pressure in the smoke channel 12 is greater than the pressure in the liquid storage chamber 13, since the regulating member 40 is disposed at one end of the vent hole 30 facing the liquid storage chamber 13, the regulating member 40 opens the vent hole 30 under the pressure difference between the two, and the aerosol in the smoke channel 12 enters the liquid storage chamber 13; when the pressure in the smoke channel 12 is less than the pressure in the liquid storage chamber 13, the regulating member 40 covers the vent hole 30 under the pressure difference between the two. In the embodiment of the present application, the above arrangement achieves a balance between the pressure difference between the liquid storage chamber 13 and the smoke channel 12 by controlling the aerosol entering the liquid storage chamber 13 from the smoke channel 12, so that the smoke oil in the liquid storage chamber 13 penetrates into the atomization assembly 50 at a uniform speed to achieve atomization, which has the beneficial effect of avoiding the occurrence of excessive atomized smoke oil causing oil explosion and the smoke oil inlet or too little smoke oil causing insufficient smoke volume, which affects the user experience.

[0034] It should be noted that the material of the bracket 20 can be plastic. The bracket 20 made of plastic can form a seal with the housing 10 to prevent the leakage of the e-liquid. In practical applications, the atomized e-liquid needs to be heated, and the plastic material also has high temperature resistance and is not easily affected by high temperature. In other words, even if the bracket 20 made of plastic is close to or in contact with a component with a higher temperature, it will not deform or melt due to the high temperature and produce odor.

[0035] It should also be noted that if Figure 4 As shown, the aperture of the vent hole 30 is L, where 0.5 mm ≤ L ≤ 1.5 mm. Specifically, the vent hole 30 can be set to one or more, and the cross-sectional shape of the vent hole 30 can be variable, and can be circular, square, elliptical or irregular, etc. The side length of the cross section of the square hole can be greater than or equal to 0.5 mm and less than or equal to 1.5 mm. At this time, the flow rate of the aerosol flowing from the smoke channel 12 into the vent hole 30 can prevent the liquid storage chamber 13 from being in a negative pressure state, and can also prevent the oil accumulation on the oil guide 51 due to excessive flow rate.

[0036] Optionally, in an embodiment of the present application, the bracket 20 also includes a bracket 20 body, the bracket 20 body includes an atomization chamber wall 221, the atomization chamber wall 221 is connected to the side of the connecting end 21 away from the airway wall 11; the smoke channel 12 includes an atomization section 121 and an exhaust section 122 that are interconnected, the atomization chamber wall 221 encloses the atomization section 121, and the airway wall 11 encloses the exhaust section 122.

[0037] In the embodiment of the present application, the smoke channel 12 includes an atomization section 121 and an air extraction section 122 that are interconnected. In actual application, the smoke oil is atomized into smoke in the atomization section 121, and the atomization cavity wall 221 is provided to enclose the atomization section 121. The smoke flows from the atomization section 121 to the air extraction section 122 as the user inhales, and then flows along the air extraction section 122 to the air outlet, and is finally inhaled by the user. The airway wall 11 is provided to enclose the air extraction section 122. Specifically, the atomization cavity wall 221 is connected to the side of the connection end 21 away from the airway wall 11. It can be understood that the atomization section 121 formed by the atomization cavity wall 221 and the air extraction section 122 formed by the airway wall 11 are interconnected, which has the function of enabling the user to inhale the smoke formed in the atomization section 121.

[0038] Optionally, in the embodiment of the present application, the main body of the bracket 20 also includes a transition portion 222, which is clamped between the connecting end 21 and the atomizing chamber wall 221 along the length direction of the electronic cigarette cartridge, and the transition portion 222 is provided with a first hole 2221 along the length direction of the electronic cigarette cartridge; the connecting end 21 is fixed to the opening of the first hole 2221, and the atomizing section 121 and the exhaust section 122 are connected through the first hole 2221.

[0039] In the embodiment of the present application, the setting of the transition part 222 is used to realize the connection between the connecting end 21 and the atomizing chamber wall 221, and the first hole 2221 provided on the transition part 222 is used to realize the connection between the atomizing section 121 and the air extraction section 122. Specifically, the connecting end 21 and the atomizing chamber wall 221 are relatively arranged on both sides of the transition part 222, and the connecting end 21 and the atomizing chamber wall 221 are indirectly connected to each other through the transition part 222. Since the atomizing chamber wall 221 encloses the atomizing section 121 and the airway wall 11 encloses the air extraction section 122, it can be understood that the process of atomizing the e-liquid to form smoke occurs in the area enclosed by the transition part 222 and the atomizing chamber wall 221. When the smoke flows through the first hole 2221 with the user's inhalation, it enters the area enclosed by the transition part 222 and the connecting end 21, and then mixes with the outside air to form an aerosol and flows to the air outlet.

[0040] Optionally, in the embodiment of the present application, the main body of the bracket 20 also includes an enclosure portion 223, which is connected to the side of the transition portion 222 away from the connection end 21, and the enclosure portion 223 is arranged on the periphery of the atomization chamber wall 221. The enclosure portion 223 and the atomization chamber wall 221 enclose a liquid flow chamber 224, and the enclosure portion 223 is away from the outer wall of the liquid flow chamber 224 and contacts the inner wall of the shell 10.

[0041] In the embodiment of the present application, the enclosure 223 is arranged on the periphery of the atomizing chamber wall 221, and the enclosure 223 is arranged to enclose with the atomizing chamber wall 221 to form a liquid flow chamber 224, and the liquid flow chamber 224 is arranged to provide a flow passage for the smoke oil in the liquid storage chamber 13, so as to realize the drainage of the smoke oil in the liquid storage chamber 13 to the position of atomizing the smoke oil. The enclosure 223 is arranged in the shell 10, and the enclosure 223 is away from the outer wall of the flow chamber and contacts the inner wall of the shell 10, and the smoke oil stored in the liquid storage chamber 13 surrounded by the shell 10 can flow into the liquid flow chamber 224.

[0042] It should be noted that a first sealing ring 70 may be sleeved around the periphery of the enclosure 223, and the first sealing ring 70 is sandwiched between the outer wall of the enclosure 223 away from the liquid flow cavity 224 and the inner wall of the housing 10. The first sealing ring 70 may be deformed, and when the outer wall of the enclosure 223 away from the liquid flow cavity 224 and the inner wall of the housing 10 are pressed against each other at the same time, the first sealing ring 70 deforms to achieve sealing between the outer wall of the enclosure 223 away from the liquid flow cavity 224 and the inner wall of the housing 10, which has the beneficial effect of preventing the smoke oil from seeping out of the gap between the outer wall of the enclosure 223 away from the liquid flow cavity 224 and the inner wall of the housing 10.

[0043] Optionally, in the embodiment of the present application, the transition portion 222 is further provided with a second hole 2222 along the length direction of the electronic cigarette cartridge; the liquid storage chamber 13 and the liquid flow chamber 224 are connected through the second hole 2222 .

[0044] In the embodiment of the present application, the second hole 2222 is provided to achieve the connection between the liquid storage chamber 13 and the liquid flow chamber 224, and the liquid flow chamber 224 is provided to provide a flow passage for the smoke oil in the liquid storage chamber 13. In practical applications, the smoke oil is usually atomized by an atomization assembly 50, and the atomization assembly 50 generally includes an oil guide member 51 for adsorbing the smoke oil. In the embodiment of the present application, part of the oil guide member 51 extends into the liquid flow chamber 224 to achieve adsorption of the smoke oil. Specifically, the smoke oil in the liquid storage chamber 13 enters the liquid flow chamber 224 through the second hole 2222 and is then adsorbed by the oil guide member 51. The atomization assembly 50 also includes a heating wire 52 wound around the oil guide member 51, and the heating wire 52 generates heat to atomize the smoke oil adsorbed on the oil guide member 51.

[0045] Specifically, one second hole 2222 may be provided on the transition portion 222, or two oppositely arranged second holes 2222 may be provided, or a plurality of evenly distributed second holes 2222 may be provided. The number and specific opening positions of the second holes 2222 may be determined according to actual conditions, and this embodiment does not impose any limitation on this.

[0046] Optionally, in the embodiment of the present application, the adjusting member 40 is a cylindrical structure, which includes a first cylinder 41 , and the first cylinder 41 is provided with a movable portion 411 ; the first cylinder 41 is sleeved on the connecting end 21 , and the movable portion 411 covers the location of the vent hole 30 .

[0047] In the embodiment of the present application, the adjusting member 40 of the cylindrical structure can be sleeved on the connecting end 21 to facilitate the connection between the adjusting member 40 and the connecting end 21. The first cylinder 41 is provided to close or open the vent 30. Specifically, the first cylinder 41 is sleeved on the connecting end 21. The first cylinder 41 is provided with a movable portion 411. When the pressure in the smoke channel 12 is lower than the pressure in the liquid storage chamber 13, the movable portion 411 covers the part of the vent 30. It can be understood that in the above case, the smoke in the smoke channel 12 cannot enter the liquid storage chamber 13 from the vent 30.

[0048] Optionally, in the embodiment of the present application, along the axial direction of the first cylinder 41 , the first cylinder 41 is provided with two slits 4111 , the length of the slit 4111 is smaller than the height of the first cylinder 41 ; and a movable portion 411 is formed between the two slits 4111 .

[0049] In the embodiment of the present application, the slit 4111 is provided to release the partial constraint of the movable part 411 by other parts of the first cylinder 41. Further, the movable part 411 is formed between the two slits 4111 opened on the first cylinder 41, and the movable part 411 covers the part where the vent 30 is located. When there is a pressure difference between the two sides of the movable part 411, that is, between the smoke channel 12 and the liquid storage chamber 13, the movable part 411, which is no longer constrained by other parts of the first cylinder 41, can move. For example, when the pressure in the smoke channel 12 is greater than the pressure in the liquid storage chamber 13, the movable part 411 moves in a direction away from the vent 30 under the action of air pressure, and the aerosol in the smoke channel 12 can enter the liquid storage chamber 13 from the vent 30 to achieve pressure balance between the smoke channel 12 and the liquid storage chamber 13. When the pressure in the smoke channel 12 is lower than the pressure in the liquid storage chamber 13, the movable part 411 is covered by the air pressure on the vent 30 to prevent the aerosol in the smoke channel 12 from entering the liquid storage chamber 13 from the vent 30. Under the action of the pressure difference, the movable part 411 can be set to open or close the vent 30, specifically to adjust the pressure balance in the smoke channel 12 and the liquid storage chamber 13, so that the smoke oil in the liquid storage chamber 13 can penetrate into the atomization assembly 50 at a uniform speed to achieve atomization, which has the beneficial effect of avoiding the occurrence of excessive atomized smoke oil causing oil explosion and insufficient smoke oil inlet or too little smoke oil, thereby improving user experience.

[0050] It should be noted that the setting of the length of the slit 4111 being smaller than the height of the first cylinder 41 can enable part of the movable part 411 to be connected to other parts of the first cylinder 41, that is, the other parts of the first cylinder 41 also have partial constraints on the movable part 411, and can achieve connection with the movable part 411 while the movable part 411 can move with the pressure difference between the smoke channel 12 and the liquid storage chamber 13, which has the beneficial effect of preventing the movable part 411 from falling off and leaving the location of the vent hole 30, resulting in the inability to achieve the pressure regulation between the smoke channel 12 and the liquid storage chamber 13 by the movable part 411.

[0051] It should also be noted that the movable portion 411 has a certain deformation capability.

[0052] Furthermore, there is an overlap width H between the movable portion 411 and the edge of the vent 30, and the overlap width H is greater than or equal to 0.3 mm and less than or equal to 1.0 mm. Specifically, there is an overlap width H between the movable portion 411 and the vent 30 along the length direction of the electronic cigarette cartridge. It should be noted that when H is less than 0.3 mm, the width of the overlapping portion is relatively small, which may easily lead to a gap between the movable portion 411 and the edge of the vent 30 being too large when the movable portion 411 closes the vent 30, and the aerosol in the smoke channel 12 may easily enter the liquid storage chamber 13, resulting in excessive smoke oil being accumulated on the oil guide 51, which may cause the heating wire 52 to fail to atomize in time, causing oil explosion and affecting the experience of smoke entering the mouth. When H>1.0mm, the width of the overlapped part is large, which may easily lead to the gap between the movable part 411 and the edge of the vent 30 being too small when the movable part 411 opens the vent 30, and the aerosol in the smoke channel 12 is difficult to enter the liquid storage chamber 13, and it will be difficult to balance the pressure difference between the liquid storage chamber 13 and the smoke channel 12 in time through the vent 30, resulting in poor ventilation of the liquid storage chamber 13, and the smoke oil in the liquid storage chamber 13 is difficult to completely infiltrate the oil guide 51 under the negative pressure, resulting in a low amount of smoke atomized by the heating wire 52, and a poor smoke taste. At this time, the heating of the heating wire 52 may cause the cotton core to burn dry, resulting in a burnt smell when inhaling. The limitation of the overlap width has the beneficial effect of improving the accuracy of controlling the pressure difference between the inside and outside of the electronic cigarette cartridge, thereby improving the user experience.

[0053] Furthermore, if Figure 4 As shown, the thickness of the movable part 411 is R, wherein 0.4mm≤R≤0.8mm. The movable part 411 within the above thickness range can open the vent 30 to allow the aerosol in the smoke channel 12 to enter the liquid storage chamber 13 to achieve timely ventilation without oil leakage. If the thickness of the movable part 411 is less than 0.4mm, the processing of the movable part 411 is more difficult. If the thickness of the movable part 411 is greater than 0.8mm, the force required for the movable part 411 to open the vent 30 is greater. The embodiments of the present application have the beneficial effect of improving the accuracy of controlling the pressure difference between the inside and outside of the electronic cigarette cartridge, thereby improving the user experience.

[0054] Furthermore, the thickness R of the movable portion 411 may be greater than or equal to 0.4 mm and less than or equal to 0.5 mm. For example, the thickness R of the movable portion 411 may be 0.4 mm, 0.45 mm, 0.55 mm, 0.6 mm, 0.7 mm, etc., to further improve the effect of ventilation and oil leakage prevention.

[0055] Optionally, in an embodiment of the present application, the cylindrical structure also includes a second cylinder 42; the second cylinder 42 is connected to the first cylinder 41 and is located inside the first cylinder 41, a connecting groove 43 is formed between the inner wall of the first cylinder 41 and the outer wall of the second cylinder 42, and the connecting end 21 is inserted into the connecting groove 43; the second cylinder 42 is clamped between the airway wall 11 and the connecting end 21.

[0056] In the embodiment of the present application, the second barrel 42 is provided to facilitate the connection between the cylindrical structure and the connecting end 21. At the same time, the second barrel 42 also improves the sealing between the airway wall 11 and the connecting end 21, and prevents the smoke oil in the liquid storage chamber 13 from leaking from between the airway wall 11 and the connecting end 21. The second barrel 42 is connected to the first barrel 41 and is located inside the first barrel 41. It can be understood that since the first barrel 41 is sleeved on the connecting end 21, and the second barrel 42 is located inside the first barrel 41, the second barrel 42 and the connecting end 21 are closer than the first barrel 41. A connecting groove 43 is formed between the inner wall of the first barrel 41 and the outer wall of the second barrel 42, and the connecting groove 43 is provided for connecting with the connecting end 21. Specifically, the connecting end 21 is inserted into the connecting groove 43 to achieve the connection between the cylindrical structure and the connecting end 21. In the case of the above-mentioned connection method, the second cylinder 42 is clamped between the airway wall 11 and the connecting end 21. When the connecting end 21 and the airway wall 11 are relatively squeezed at the same time, the second cylinder 42 can achieve sealing between the connecting end 21 and the airway wall 11, which has the beneficial effect of preventing the smoke oil from seeping out of the gap between the connecting end 21 and the airway wall 11.

[0057] It should be noted that, except for the movable portion 411, other parts of the cylindrical structure also have certain deformation capabilities. When the connecting end 21 and the airway wall 11 are pressed against each other, the second cylinder 42 can be deformed to achieve sealing between the connecting end 21 and the airway wall 11.

[0058] Optionally, in the embodiment of the present application, the adjusting member 40 is a diaphragm structure; a portion of the edge of the diaphragm structure is fixedly connected to the location of the vent hole 30 .

[0059] In the embodiment of the present application, the diaphragm structure is used to move under the pressure difference between the smoke channel 12 and the liquid storage chamber 13 to open or close the vent 30. Part of the edge of the diaphragm structure is fixedly connected to the part where the vent 30 is located, that is, the diaphragm structure can be arranged on the airway wall 11 or the connection end 21 where the vent 30 is opened. The diaphragm structure can move under the pressure difference between the smoke channel 12 and the liquid storage chamber 13. Specifically, when the pressure in the smoke channel 12 is greater than the pressure in the liquid storage chamber 13, the diaphragm structure moves in the direction away from the vent 30 under the action of the air pressure, and the smoke aerosol in the smoke channel 12 can enter the liquid storage chamber 13 from the vent 30 to achieve pressure balance between the smoke channel 12 and the liquid storage chamber 13. When the pressure in the smoke channel 12 is lower than the pressure in the liquid storage chamber 13, the diaphragm structure is covered by the air pressure on the vent 30, preventing the smoke aerosol in the smoke channel 12 from entering the liquid storage chamber 13 from the vent 30. Under the action of the pressure difference, the diaphragm structure can be set to open or close the vent 30, specifically to adjust the pressure balance in the smoke channel 12 and the liquid storage chamber 13, so that the smoke oil in the liquid storage chamber 13 can penetrate into the atomization assembly 50 at a uniform speed to achieve atomization, which has the beneficial effect of avoiding the occurrence of excessive atomized smoke oil causing oil explosion and insufficient smoke oil inlet or too little smoke oil, thereby improving user experience.

[0060] It should be noted that the edge of the diaphragm structure may be bonded to the airway wall 11 or the connection end 21 , or may be connected via a connector, and this embodiment does not impose any limitation on this.

[0061] It should also be noted that the diaphragm structure is relatively light and can move under the action of pressure difference. This embodiment does not impose any restrictions on the specific material and specific weight of the diaphragm structure, and can open and close the vent hole 30 under the action of pressure difference.

[0062] Optionally, in an embodiment of the present application, the electronic cigarette cartridge also includes an atomizer assembly 50 and a cover body 60, the cover body 60 and the shell 10 are fixedly connected, the bracket 20 and the cover body 60 are fixedly connected, the atomizer assembly 50 is clamped between the bracket 20 and the cover body 60, and the atomizer assembly 50 is arranged in the smoke channel 12.

[0063] In the embodiment of the present application, the cover body 60 and the housing 10 are fixedly connected, and further, the interference fit between the cover body 60 and the housing 10 has the function of preventing the leakage of smoke oil. The bracket 20 presses the atomizer assembly 50 to the cover body 60, and the cover body 60 and the bracket 20 cooperate to fix the atomizer assembly 50. Specifically, the cover body 60 may include a first bracket 7120, a second bracket 7220 and a lower cover assembly 73 that are sequentially snapped together, and the lower cover assembly 73 is arranged at the opening of the housing 10, the bracket 20 presses the atomizer assembly 50 to the first bracket 7120, and the bracket 20 and the first bracket 7120 cooperate to fix the atomizer assembly 50. Specifically, a mounting groove is provided on the end face of the first bracket 7120 facing the atomizer assembly 50, and the atomizer assembly 50 is fixed by using the mounting groove, and its fixing structure is simple and has high stability.

[0064] Further, the lower cover assembly 73 may include a main body 74, a second sealing ring 75, a liquid absorbing member 76, a receiving member 77 and a conductive nail 78. The main body 74 is provided with a connection hole, and the conductive nail 78 is connected with the connection hole. The second sealing ring 75 is sleeved on the periphery of the main body 74 and clamped between the main body 74 and the shell 10. The second sealing ring 75 is provided to achieve a seal between the main body 74 and the shell 10 to prevent the smoke oil in the liquid storage chamber 13 from leaking from the connection between the main body 74 and the shell 10. In addition, the main body 74 is also provided with an air inlet that is connected to the outside atmosphere. The air inlet is connected to the smoke channel 12. A receiving member 77 is provided at one end of the air inlet facing the atomization chamber. A liquid absorbing member 76 may be provided at the bottom of the atomization section 121. The liquid absorbing member 76 is provided on the side of the receiving member 77 facing the atomization section 121. The liquid absorbing member 76 can be used to collect condensed liquid in the atomization section 121.

[0065] Further, the atomization assembly 50 may include an oil guide 51 and a heating wire 52, at least a portion of the heating wire 52 is wound around the oil guide 51 in a spiral form, for example, the oil guide 51 may be a cylindrical member extending in the horizontal direction, and the heating wire 52 is wound around the oil guide 51 in the circumferential direction and extends approximately in the axial direction of the oil guide 51. By arranging the heating wire 52 on the oil guide 51, when the user is smoking the electronic cigarette cartridge, the heating wire 52 can heat the oil guide 51 adsorbed with tobacco oil, so that the tobacco oil on the heating wire 52 is atomized and smoke is generated, and the generated smoke can be mixed with the airflow flowing into the atomization chamber from the outside atmosphere, and then introduced into the user's mouth through the air outlet. By winding the heating wire 52 around the outer surface of the oil guide 51, on the one hand, the contact area between the heating wire 52 and the outer surface of the oil guide 51 can be increased, which is conducive to the tobacco oil on the oil guide 51 being fully atomized, increasing the amount of smoke generated by atomization, and improving the taste, and on the other hand, the stability of the connection between the heating wire 52 and the oil guide 51 can also be improved.

[0066] It should be noted that the oil guide member 51 can be a cotton core, part of which extends into the liquid flow cavity 224, and part of which is arranged in the atomization section 121. By utilizing the cotton core's ability to adsorb smoke oil, the smoke oil in the liquid storage cavity 13 can be transported to the atomization section 121 for atomization.

[0067] Furthermore, the cotton core can be a long strip of liquid-absorbing cotton, which can extend in the left and right directions. The two ends of the cotton core can respectively extend into the liquid flow cavity 224, and the middle part of the cotton core can be located in the atomization section 121. The smoke oil in the liquid flow cavity 224 can gradually penetrate the entire cotton core through the end of the cotton core. The cotton core can absorb the smoke oil until it reaches a saturated state, thereby realizing the transport of the smoke oil from the liquid flow cavity 224 to the atomization section 121 to facilitate liquid atomization.

[0068] Optionally, in an embodiment of the present application, an electronic cigarette is also provided, comprising the electronic cigarette cartridge as described above.

[0069] In the embodiment of the present application, the electronic cigarette includes the electronic cigarette cartridge described in any of the above embodiments. By providing the vent hole 30 and the adjusting member 40 that cooperate with each other on the electronic cigarette cartridge, the air intake rate of the gas entering the liquid storage chamber 13 from the vent hole 30 can be adjusted, thereby balancing the pressure between the liquid storage chamber 13 and the smoke passage 12. Specifically, when the pressure in the smoke passage 12 is greater than the pressure in the liquid storage chamber 13, since the adjusting member 40 is provided at one end of the vent hole 30 facing the liquid storage chamber 13, the adjusting member 40 opens the vent hole 30 under the pressure difference between the two, and the aerosol in the smoke passage 12 enters the liquid storage chamber 13; when the pressure in the smoke passage 12 is less than the pressure in the liquid storage chamber 13, the adjusting member 40 covers the vent hole 30 under the pressure difference between the two. In the embodiment of the present application, the above-mentioned setting achieves a balanced pressure difference between the liquid storage chamber 13 and the smoke channel 12 by controlling the aerosol entering the liquid storage chamber 13 from the smoke channel 12, so that the smoke oil in the liquid storage chamber 13 penetrates into the atomization component 50 at a uniform speed to achieve atomization, thereby avoiding the problem of excessive atomized smoke oil causing oil explosion and insufficient smoke volume due to the inlet of smoke oil or too little smoke oil, which leads to poor user experience, and has the beneficial effect of improving user experience.
