Description

Technical Field

[0001] This application belongs to the field of electronic cigarette technology, and particularly relates to a cartridge for electronic cigarettes and an electronic cigarette. Background Technology

[0002] Refillable e-cigarettes consist of a device and detachable cartridges attached to it. Once the e-liquid in the cartridge is used up, users can replace the cartridge to continue using the device, thus aligning with environmental principles and conserving resources. The cartridge has an e-liquid storage chamber and an atomizing chamber. The storage chamber holds the e-liquid, which enters the atomizing chamber through an inlet, where it is heated and evaporated into vapor. An air intake is located at the bottom of the cartridge. When the user inhales, outside air enters through this air intake, mixes with the vapor, and then flows through the cartridge's outlet to the mouthpiece for inhalation.

[0003] However, this type of e-liquid cartridge also has the following drawbacks: On the one hand, during the user's vaping process, as the e-liquid in the reservoir chamber enters the atomizing chamber, the reduced amount of e-liquid in the reservoir chamber creates negative pressure. This negative pressure makes it difficult for the e-liquid in the reservoir chamber to smoothly enter the atomizing chamber, causing the cartridge to dry-burn. On the other hand, after the user finishes vaping, outside air can enter the reservoir chamber through the mouthpiece, mist outlet, atomizing chamber, and e-liquid inlet channel. Changes in outside air pressure may cause an increase in pressure inside the reservoir chamber, which in turn forces e-liquid into the e-liquid inlet channel and atomizing chamber, resulting in e-liquid leakage. Alternatively, if the cartridge is stored in a high-temperature environment, the air inside the reservoir chamber will expand due to heat, increasing the pressure inside the reservoir chamber and forcing e-liquid into the e-liquid inlet channel and atomizing chamber, resulting in e-liquid leakage. Summary of the Invention

[0004] The purpose of this application is to provide a cartridge and an electronic cigarette for use in electronic cigarettes, aiming to solve the technical problems of existing electronic cigarette cartridges being prone to dry burning and e-liquid leakage.

[0005] To achieve the above objectives, firstly, the technical solution adopted in this application is to provide a cartridge for an electronic cigarette, the cartridge comprising:

[0012] Optionally, the housing assembly has a vent hole on the part located outside the self-deformable separator, and the vent hole communicates with the external space of the housing assembly.

[0013] Optionally, an air intake gap is provided between the inner wall of the housing assembly and the self-deformable partition, and the air intake gap communicates with the external space of the housing assembly through the vent hole.

[0014] Optionally, a filter is provided inside the vent, and the filter only allows air to pass through.

[0015] Optionally, the self-deformable separator is made of an elastic material.

[0016] Optionally, the self-deformable separator is made of a flexible membrane; or, the self-deformable separator is made of a plastic shell.

[0017] Optionally, the housing assembly includes a housing and a sealing seat, the nozzle is disposed at one end of the housing, the other end of the housing has an opening, the sealing seat is inserted into the opening, the housing is made of hard rubber material, the self-deformable separator is made of silicone material, and the air inlet gap is disposed between the inner wall of the housing and the self-deformable separator.

[0018] Optionally, one end of the self-deformable separator is sealed to the outer wall of the aerosol channel, and the other end of the self-deformable separator is sealed to the outer wall of the sealing seat.

[0019] Optionally, the aerosol channel includes an atomizing tube and a mist outlet tube. The mist outlet tube is a pipe provided inside the housing that communicates with the mouthpiece. The atomizing tube is inserted into the sealing seat, and the end of the atomizing tube away from the sealing seat is connected to the mist outlet tube.

[0020] The self-deformable separator is provided with a first sealing ring and a second sealing ring around one end of the aerosol channel. The first sealing ring abuts against the outer wall of the mist outlet tube, and the second sealing ring abuts against the outer wall of the atomizing tube.

[0021] Optionally, the self-deformable separator has an annular protrusion around one end of the sealing seat and one of the outer wall of the sealing seat, and an annular groove around the other end of the sealing seat and one of the outer wall of the sealing seat, and the annular protrusion is interference-fitted into the annular groove.

[0022] Alternatively, a third sealing ring may be provided on one end of the self-deformable separator surrounding the sealing seat, and the third sealing ring abuts against the outer wall of the sealing seat.

[0023] Optionally, the self-deformable separator includes a main body, a first sealing ring, a second sealing ring, and an annular protrusion, wherein the first sealing ring, the second sealing ring, and the annular protrusion are all manufactured together with the main body through a double-shot molding process.

[0024] Optionally, the main body includes a cylindrical body and two plug-in terminals disposed at the same end of the cylindrical body. An avoidance groove is formed between the two plug-in terminals. The mist outlet tube extends into the avoidance groove and abuts against the first sealing ring.

[0026] Optionally, at least a portion of the housing assembly is made of a transparent material, and the self-deformable separator is made of a transparent material.

[0027] According to the first aspect of the embodiments of this application, a cartridge for an electronic cigarette is defined by a self-deformable separator and the outer wall of the aerosol channel to form an oil storage cavity. The self-deformable separator can collapse and deform towards the aerosol channel as the amount of e-liquid in the oil storage cavity decreases. Therefore, when the amount of e-liquid in the oil storage cavity decreases, a negative pressure will not be formed in the oil storage cavity. Thus, the e-liquid in the oil storage cavity can smoothly enter the aerosol channel, thereby preventing the cartridge from dry burning even without a ventilation structure. Furthermore, because the self-deformable separator collapses and deforms towards the aerosol channel as the amount of e-liquid decreases, the oil storage cavity is always full of e-liquid. A negative pressure will not be formed in the oil storage cavity, and outside air cannot enter the oil storage cavity through the aerosol channel and the oil inlet channel. Therefore, even if the cartridge is stored in a high-temperature environment or the external air pressure of the cartridge changes, the pressure inside the oil storage cavity will not increase, thereby preventing e-liquid leakage that may be caused by the e-liquid being forced into the oil inlet channel and the aerosol channel. In addition, since outside air does not enter the oil storage chamber, no bubble zone will be generated inside the oil storage chamber, thus avoiding the bubble zone from interfering with the e-liquid entering the aerosol channel through the oil inlet channel.

[0028] Secondly, this application also provides an electronic cigarette, including a cartridge and a device for electronic cigarettes according to the first aspect of the embodiments of this application, wherein the cartridge and the device are electrically connected, the cartridge and the device are an integral structural component, or the cartridge is detachably mounted on the device.

[0029] The electronic cigarette according to the second aspect of the present application includes the cartridge for electronic cigarettes according to the first aspect of the present application, so it can also avoid dry burning of the cartridge and avoid leakage of e-liquid.

[0048] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0049] Please see Figure 1-4This application provides a cartridge 1 for an electronic cigarette. The cartridge 1 includes a shell assembly, an atomizing assembly 500, an aerosol channel, and a self-deforming separator 300. One end of the shell assembly is provided with a mouthpiece 110. The atomizing assembly 500 is disposed inside the shell assembly and is used to convert the e-liquid stored in the cartridge 1 into atomized gas. The aerosol channel is disposed inside the shell assembly and communicates with the mouthpiece 110. The aerosol channel is used to allow the atomized gas to be carried to the mouthpiece 110 by the airflow. The self-deformable separator 300 is sealed to the inner wall of the housing assembly and / or the outer wall of the aerosol channel. The self-deformable separator 300 and the outer wall of the aerosol channel define an oil storage cavity 900 for storing e-liquid. The housing assembly has an oil inlet channel 410 that connects the oil storage cavity 900 and the aerosol channel. The e-liquid in the oil storage cavity 900 enters the aerosol channel through the oil inlet channel 410. The self-deformable separator 300 can collapse and deform towards the aerosol channel as the e-liquid in the oil storage cavity 900 decreases.

[0050] It should be noted that the aerosol channel includes the channel inside the cartridge 1 that generates atomized gas and the channel that allows the atomized gas to communicate with the outside world. In other words, the aerosol channel is equivalent to the combination of the atomization channel and the mist output channel of existing electronic cigarette cartridges.

[0051] It should be noted that the self-deformable separator 300 being sealed to the inner wall of the housing assembly and / or the outer wall of the aerosol channel means that the self-deformable separator 300 can be sealed only to the inner wall of the housing assembly, thereby forming an oil storage cavity 900 with the self-deformable separator 300, the inner wall of the housing assembly, and the outer wall of the aerosol channel; or the self-deformable separator 300 can be sealed only to the outer wall of the aerosol channel, thereby forming an oil storage cavity 900 with the self-deformable separator 300 and the outer wall of the aerosol channel; or one end of the self-deformable separator 300 can be sealed to the inner wall of the housing assembly, and the other end of the self-deformable separator 300 can be sealed to the outer wall of the aerosol channel, thereby forming an oil storage cavity 900 with the self-deformable separator 300, the inner wall of the housing assembly, and the outer wall of the aerosol channel. The ability of the self-deformable separator 300 to collapse and deform towards the aerosol channel means that the self-deformable separator 300 can deform inward towards the aerosol channel as the e-liquid decreases. During this process, the oil reservoir 900 contracts, and at least a portion of the self-deformable separator 300 moves closer to the aerosol channel. In other words, the ability of the self-deformable separator 300 to collapse and deform towards the aerosol channel means that the self-deformable separator 300 can automatically reduce the volume of the oil reservoir 900 by an equivalent amount according to the amount of e-liquid consumed.

[0052] It should be noted that the e-liquid reservoir 900 can be filled with e-liquid, with little or no gas present. As the e-liquid in the reservoir 900 is consumed, the self-deformable separator 300 collapses and deforms towards the aerosol channel, causing the reservoir 900 to shrink. During this process, no negative pressure is created within the reservoir 900, thus preventing outside air from entering.

[0053] The e-liquid cartridge 1 provided in this application embodiment defines an oil storage cavity 900 between the self-deformable separator 300 and the outer wall of the aerosol channel. The self-deformable separator 300 can collapse and deform towards the aerosol channel as the amount of e-liquid in the oil storage cavity 900 decreases. Therefore, no negative pressure is formed in the oil storage cavity 900 when the amount of e-liquid decreases, allowing the e-liquid in the oil storage cavity 900 to smoothly enter the aerosol channel. This prevents the e-liquid cartridge 1 from dry burning even without a ventilation structure. Furthermore, because... The self-deformable separator 300 collapses and deforms towards the aerosol channel as the e-liquid decreases, ensuring that the e-liquid reservoir 900 remains full. This prevents negative pressure from forming in the reservoir, thus preventing outside air from entering through the aerosol channel and the e-liquid inlet channel 410. Consequently, even if the cartridge 1 is stored in a high-temperature environment or the external air pressure changes, the pressure inside the reservoir 900 will not increase, preventing e-liquid leakage that could result from being forced into the e-liquid inlet channel 410 and the aerosol channel. Furthermore, because outside air does not enter the reservoir 900, no air bubbles are generated within it, preventing these bubbles from interfering with the e-liquid entering the aerosol channel through the e-liquid inlet channel 410.

[0054] In one embodiment, the oil inlet channel 410 is configured to allow only unidirectional flow of e-liquid in the oil storage chamber 900 to the aerosol channel, while disallowing reverse flow of fluid in the aerosol channel to the oil storage chamber 900.

[0055] For example, a one-way valve or elastic diaphragm is provided in the oil inlet channel 410 to prevent the fluid in the aerosol channel from flowing back into the oil reservoir 900. The configuration and working principle of the one-way valve and elastic diaphragm are common knowledge in the art and will not be described in detail here.

[0056] It is easy to understand that the oil inlet channel 410 is set to allow e-liquid to flow unidirectionally to the atomization channel, while not allowing the fluid in the atomization channel to flow back to the oil storage chamber 900. This can prevent residual e-liquid and condensed liquid after atomization in the atomization channel from flowing back to the oil storage chamber through the oil inlet channel 410. At the same time, it can also prevent air from outside the cartridge 1 from entering the oil storage chamber 900 through the mouthpiece 110, the atomization channel, and the oil inlet channel 410. This avoids the formation of negative pressure in the oil storage chamber 900 when air enters the oil storage chamber 900 and the amount of e-liquid in the oil storage chamber 900 decreases.

[0057] Furthermore, since residual e-liquid, condensate, and air do not enter the e-liquid storage chamber, the self-deformable separator 300 can automatically deform towards the aerosol channel when the e-liquid in the e-liquid storage chamber 900 decreases. In other words, the e-liquid inlet channel 410 of this embodiment provides a specific implementation method for the self-deformable separator 300 to have an automatic collapse deformation function. Therefore, the cartridge 1 of this embodiment does not need to have the vent 130 as described below on the shell assembly, reducing the processing steps of the cartridge 1 shell assembly, and also preventing dust and other pollutants from the external environment from contaminating or puncturing the self-deformable separator 300 through the vent 130.

[0058] Please see Figure 1 In one embodiment, the housing assembly has a vent 130 on the part located outside the self-deformable separator 300, and the vent 130 communicates with the external space of the housing assembly.

[0059] It is easy to understand that by providing a vent 130 on the housing assembly, the external atmospheric pressure can compress the outer wall of the self-deformable separator 300 through the vent 130. Therefore, when the amount of e-liquid in the oil storage chamber 900 decreases, the self-deformable separator 300 can collapse towards the aerosol pipe under the action of the external atmospheric pressure, so that the pressure inside the oil storage chamber 900 always remains in balance with the external atmospheric pressure.

[0060] It should be noted that the number and shape of the vents 130 are not limited. Please refer to [link / reference]. Figure 1 In this embodiment, only one vent 130 is provided, and the vent 130 is a circular through hole. In some other embodiments, the vent can be set as a through hole of other shapes, and there can also be multiple vents 130, which can be evenly distributed on the housing assembly.

[0061] In one embodiment, a filter is provided inside the vent 130, which allows only air to pass through.

[0062] Intuitively, the filter acts as a dustproof and protective element, preventing external dust, large particles, or other contaminants from entering the housing assembly, thereby avoiding dust, large particles, and other contaminants from puncturing or contaminating the self-deforming separator 300.

[0063] For example, the filter can be made of a semi-permeable membrane, which can be easily configured to allow only air molecules to pass through, while not allowing other particulate matter in the air to pass through.

[0064] Please see Figure 2-3 In one embodiment, an air inlet gap 800 is provided between the inner wall of the housing assembly and the self-deformable separator 300, and the air inlet gap 800 communicates with the external space of the housing assembly through the vent hole 130.

[0065] It should be noted that the air intake gap 800 is configured to allow communication with the external space of the housing assembly via the vent 130 even when the oil storage chamber 900 is filled with e-liquid.

[0066] By setting the air intake gap 800, air from outside the housing assembly can continuously enter the air intake gap 800. This ensures that the self-deformable separator 300 remains under atmospheric pressure during e-liquid consumption, causing it to collapse and deform towards the aerosol channel, thus maintaining pressure balance between the e-liquid reservoir and the external atmospheric pressure. Furthermore, the air intake gap 800 prevents the self-deformable separator 300 from directly adhering to the inner wall of the housing assembly and obstructing the entry of outside air when the e-liquid reservoir 900 is full.

[0067] In one embodiment, the self-deformable separator 300 is made of an elastic material.

[0068] In an easy-to-understand way, when the amount of e-liquid in the reservoir 900 decreases, the self-deformable separator 300, made of elastic material, can undergo elastic deformation towards the atomization channel under the influence of external atmospheric pressure; that is, the self-deformable separator 300 can collapse towards the atomization channel. Conversely, during the process of filling the reservoir 900 with e-liquid, as the amount of e-liquid in the reservoir 900 increases, the self-deformable separator 300 will expand accordingly until the filling process is completed. During this filling process, the reservoir 900 can always maintain a balance with the external atmospheric pressure.

[0069] In one embodiment, the self-deformable separator 300 is made of a flexible membrane. When the flexible membrane self-deformable separator 300, together with the inner wall of the housing assembly or the outer wall of the aerosol channel, forms an oil storage cavity 900, the flexible membrane can automatically shrink as the amount of e-liquid in the oil storage cavity 900 decreases, that is, the self-deformable separator 300 can automatically collapse and deform towards the aerosol channel.

[0070] Specifically, the flexible membrane can be a rubber membrane or a plastic membrane. The plastic membrane can be made from one or more resin materials such as polyethylene film (LDPE, HDPE, LLDPE, VLDPE, MPE), polypropylene film (CPP, BOPP), and polyvinyl chloride film (PVC), without limitation.

[0071] In one embodiment, the self-deformable separator 300 is made of a plastic housing.

[0072] It should be noted that the plastic shell here is limited to a soft plastic shell that can collapse and deform toward the aerosol channel as the amount of e-liquid in the oil storage chamber 900 decreases, and does not include a rigid plastic shell that does not collapse and deform toward the aerosol channel.

[0073] Please see Figure 1-3 In one embodiment, the housing assembly includes a housing 100 and a sealing seat 200. The nozzle portion 110 is disposed at one end of the housing 100, and the other end of the housing 100 is provided with an opening. The sealing seat 200 is inserted and installed in the opening. One end of the self-deformable separator 300 is sealed and connected to the outer wall of the aerosol channel around the aerosol channel, and the other end of the self-deformable separator 300 is sealed and connected to the outer wall of the sealing seat 200 around the sealing seat 200.

[0074] It should be noted that the sealing seat 200, as part of the housing assembly, is inserted into the opening of the housing 100. The outer wall of the sealing seat 200 exposed inside the housing 100 is actually part of the inner wall of the housing assembly.

[0075] The self-deformable separator 300, together with the outer wall of the sealing seat 200 and the outer wall of the aerosol channel, forms an oil storage cavity 900. The two ends of the self-deformable separator 300 are respectively sealed and connected to the aerosol channel and the sealing seat 200, thereby ensuring that the e-liquid in the oil storage cavity 900 can only flow to the aerosol channel through the oil inlet channel 410, and will not leak from the connection position of the self-deformable separator 300.

[0076] In one embodiment, the self-deformable separator 300 is made of silicone material, the housing 100 is made of hard plastic material, and the air inlet gap 800 is disposed between the inner wall of the housing 100 and the self-deformable separator 300.

[0077] Silicone material is readily available, resulting in a low-cost and easy-to-manufacture self-deformable separator 300. Furthermore, silicone's excellent elastic deformation capability allows the self-deformable separator 300 to collapse and deform towards the aerosol channel when the e-liquid level in the oil reservoir 900 decreases. In contrast, the hard plastic shell 100 is less prone to deformation, maintaining the normal shape of the cartridge 1 and meeting its usage requirements. On the other hand, when the cartridge 1 is exposed to high temperatures, the shell 100 deforms due to the heat, causing its internal cavity to shrink. The hard plastic shell 100 experiences less shrinkage, and the air inlet gap 800 ensures that the deformation of the shell 100 does not compress the self-deformable separator 300, thus preventing e-liquid leakage. It should be noted that "high temperature" here refers to the higher ambient temperature in certain regions and weather conditions when the cartridge 1 is used.

[0078] Preferably, the wall thickness of the self-deformable separator 300 is set to 0.1-0.4 mm. Setting the wall thickness to less than 0.4 mm makes it easier for the self-deformable separator 300 to undergo elastic deformation, thus ensuring that the self-deformable separator 300 can collapse and deform towards the aerosol channel as the amount of soy oil in the oil storage cavity 900 decreases; while setting the wall thickness to greater than 0.1 mm can prevent the self-deformable separator 300 from easily breaking, and a self-deformable separator with a thickness greater than 0.1 mm is also easier to process and manufacture.

[0079] Preferably, the air intake gap between the inner wall of the housing 100 and the self-deformable partition 300 is not less than 0.2 mm. For the housing 100 made of hard rubber material and the self-deformable partition 300 made of silicone material, an air intake gap of not less than 0.2 mm can ensure that the deformation process of the housing 100 under high temperature environment will not compress the self-deformable partition 300.

[0080] In this embodiment, the wall thickness of the self-deformable separator 300 is 0.3 mm, the air intake gap between the inner wall of the housing 100 and the self-deformable separator 300 is 0.3 mm, and the housing 100 is made of PC and PCTG.

[0081] Please see Figure 1-3 In one embodiment, the aerosol channel includes an atomizing tube 400 and an outlet tube 120. The outlet tube 120 is a pipe disposed inside the housing 100 and communicating with the mouthpiece 110. The atomizing tube 400 is inserted into the sealing seat 200, and the end of the atomizing tube 400 away from the sealing seat 200 is connected to the outlet tube 120. A self-deformable separator 300 is provided with a first sealing ring 310 and a second sealing ring 320 around one end of the aerosol channel. The first sealing ring 310 abuts against the outer wall of the outlet tube 120, and the second sealing ring 320 abuts against the outer wall of the atomizing tube 400.

[0082] It is easy to understand that by simultaneously providing a first sealing ring 310 and a second sealing ring 320 on the self-deformable separator 300, which are respectively sealed to the mist outlet pipe 120 and the atomizing pipe 400 that form the aerosol channel, the connection positions between the self-deformable separator 300 and the mist outlet pipe 120 and between the self-deformable separator 300 and the atomizing pipe 400 are kept sealed, thus achieving a double seal between the self-deformable separator 300 and the aerosol channel. This prevents the e-liquid in the oil storage chamber 900 from leaking from the connection positions between the self-deformable separator 300 and the mist outlet pipe 120 or between the self-deformable separator 300 and the atomizing pipe 400.

[0083] In one embodiment, the self-deformable separator 300 has an annular protrusion 330 around one end of the sealing seat 200 and one of the outer wall of the sealing seat 200, and an annular groove around the other end of the self-deformable separator 300 and one of the outer wall of the sealing seat 200, and the annular protrusion 330 is interference-fitted into the annular groove.

[0084] It is easy to understand that by interfering with the annular protrusion 330 in the annular groove, the connection between the self-deformable separator 300 and the sealing seat 200 can be kept sealed, thereby preventing the e-liquid in the oil storage chamber 900 from leaking from the connection between the self-deformable separator 300 and the sealing seat 200.

[0085] Please see Figure 2-3 In this embodiment, an annular protrusion 330 is disposed on one end of the self-deformable separator 300 surrounding the sealing seat 200, and an annular groove is disposed on the outer wall of the sealing seat 200.

[0086] In other embodiments, a third sealing ring is provided on one end of the self-deformable spacer 300 surrounding the sealing seat 200, and the third sealing ring abuts against the outer wall of the sealing seat 200. It is readily understood that the third sealing ring is used to seal the gap between the self-deformable spacer 300 and the outer wall of the sealing seat 200.

[0087] Please see Figure 2-4 In one embodiment, the self-deformable separator 300 includes a main body and a first sealing ring 310, a second sealing ring 320, and an annular protrusion 330. The first sealing ring 310, the second sealing ring 320, and the annular protrusion 330 are all formed with the main body through a double-shot molding process.

[0088] By using a double-shot molding process to process the main body and the first sealing ring 310, the second sealing ring 320, and the annular protrusion 330, it is possible to use different types of plastic materials for the main body and the first sealing ring 310, the second sealing ring 320, and the annular protrusion 330. By rationally selecting the type of plastic material, the main body can simultaneously have the ability to collapse and deform towards the aerosol channel as the amount of e-liquid in the oil storage cavity 900 decreases, and the first sealing ring 310, the second sealing ring 320, and the annular protrusion 330 can have good sealing performance.

[0089] Please see Figure 2-4In one embodiment, the main body includes a cylindrical main body 350 and two plug-in terminals 360 disposed at the same end of the cylindrical main body 350. A clearance groove 370 is formed between the two plug-in terminals 360. The mist outlet tube 120 extends into the clearance groove 370 and abuts against the first sealing ring 310. The atomizing tube 400 extends into the clearance groove 370 and abuts against the second sealing ring 320. The inner diameter of the atomizing tube 400 is larger than the inner diameter of the mist outlet tube 120. The mist outlet tube 120 extends into the atomizing tube 400 and communicates with the atomizing tube 400.

[0090] It is easy to understand that by setting the plug-in terminal 360 and the clearance groove 370, the internal space of the housing 100 assembly can be maximized to increase the oil storage chamber 900, while the self-deformable separator 300 can be easily fitted onto the mist outlet tube 120. The first sealing ring 310 and the second sealing ring 320 prevent gaps from forming between the mist outlet tube 120, the atomizing tube 400 and the self-deformable separator 300. The inner diameter of the atomizing tube 400 is larger than that of the mist outlet tube 120, and the mist outlet tube 120 extends into the atomizing tube 400 and communicates with it. This ensures that the atomized gas in the atomizing tube 400 can only flow outward through the mist outlet tube 120 to the mouthpiece 110, and is not easily leaked to other locations.

[0091] Please see Figure 2-4 Because the plug-in terminal 360 is inserted into the cavity formed by the mist outlet pipe 120 and the inner wall of the housing 100, it is difficult for outside air to enter this cavity. Therefore, when the self-deformable separator 300 collapses towards the mist channel, the deformation process of the plug-in terminal 360 may not be successfully achieved. To solve this problem, in this embodiment, a gap for air passage is reserved between the plug-in terminal 360 and the inner wall of the housing 100. In other embodiments, the wall thickness of the plug-in terminal 360 is set to be less than the thickness of the cylindrical body 350, which can also make the deformation process of the plug-in terminal 360 easier to achieve to some extent.

[0092] In one embodiment, the end face of the atomizing tube 400 near the mist outlet tube 120 abuts against the first sealing ring 310.

[0093] In an easy-to-understand way, by setting one end of the atomizing tube 400 close to the mist outlet tube 120 to abut against the first sealing ring 310, the gap between the atomizing tube 400 and the mist outlet tube 120 can be sealed by the first sealing ring 310, thereby preventing the oil storage chamber 900 from communicating with the aerosol channel through the gap between the second sealing ring 320 and the outer wall of the atomizing tube 400.

[0094] In one embodiment, both the housing 100 and the self-deformable partition 300 are made of transparent material. The e-liquid stored in the oil reservoir 900 is generally a colored liquid. By making both the housing 100 and the self-deformable partition 300 transparent, it is convenient for the user to observe the consumption of e-liquid in the oil reservoir 900 and the deformation process of the self-deformable partition 300.

[0095] Please see Figure 1 In one embodiment, the nozzle portion 110 is a horn-shaped channel provided on the housing 100, and the nozzle portion 110 is configured to gradually increase in inner diameter along the direction away from the mist outlet pipe 120.

[0096] Please see Figure 1 In one embodiment, the oil inlet channel 410 is an oil inlet through hole provided on the atomizing tube 400 that connects the oil storage chamber 900 and the inner cavity of the atomizing tube 400.

[0097] Please see Figure 1 In one embodiment, the atomizing component 500 is disposed inside the atomizing tube 400, so that the atomized gas generated by the atomizing component 500 converting e-liquid can flow directly from inside the atomizing tube 400 to the mist outlet tube 120, and further flow from the mouthpiece 110 to the outside space, so as to be inhaled by the user.

[0098] In some other embodiments, the atomizing component 500 may also be located directly below the opening at one end of the atomizing tube 400, as long as the e-liquid stored in the oil storage chamber 900 can reach the atomizing component 500 through the oil inlet channel 410, and the atomized gas generated by the atomizing component 500 from the e-liquid can enter the atomizing tube 400.

[0099] Please see Figure 1 In one embodiment, the cartridge 1 further includes an oil-guiding cotton 600, which is sandwiched between the atomizing tube 400 and the atomizing component 500 and is connected to the oil inlet channel 410. The oil-guiding cotton 600 is used to guide the e-liquid delivered from the oil inlet channel 410 to the atomizing component 500.

[0100] In this embodiment, the atomizing assembly 500 includes an atomizing bracket 510, an atomizing core 520, and a heating wire connected to the atomizing core 520, all installed inside the atomizing tube 400. The e-liquid in the oil storage chamber 900 enters the atomizing tube 400 through the oil inlet channel 410, passes through the atomizing bracket 510, and reaches the atomizing core 520, whereby the heating wire heats and evaporates the e-liquid into atomized gas.

[0101] Please see Figure 1In one embodiment, a fourth sealing ring 340 is further provided on one end of the self-deformable separator 300 surrounding the sealing seat 200, and the fourth sealing ring 340 abuts against the inner wall of the housing 100. It is readily understood that the fourth sealing ring 340 is used to seal the gap between the self-deformable separator 300 and the inner wall of the housing 100.

[0102] Please see Figure 1 In one embodiment, the cartridge 1 further includes a fifth sealing ring 700, which is press-fitted between the outer wall of the sealing seat 200 and the inner wall of the housing 100, and the fifth sealing ring 700 is located inside the housing assembly at one end closer to the sealing seat 200 than the self-deformable separator 300.

[0103] It is easy to understand that by setting the fifth sealing ring 700, the sealing effect at the connection between the housing 100 and the sealing seat 200 is ensured, thereby preventing outside air from entering the air intake gap 800 through the vent 130 and leaking through the connection between the housing 100 and the sealing seat 200. This also prevents the self-deformable separator 300 from collapsing towards the aerosol channel, which may have been caused by this.

[0104] In addition, this application embodiment also provides an electronic cigarette, which includes a cartridge 1 and a cigarette rod as described in the above embodiment. The cartridge 1 is electrically connected to the cigarette rod, and the cartridge 1 and the cigarette rod are an integral structural component, or the cartridge 1 is detachably installed on the cigarette rod.

[0105] The electronic cigarette provided in this application embodiment includes the aforementioned cartridge 1, thus also preventing the cartridge 1 from burning dry and preventing e-liquid leakage.

[0106] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
