This application claims priority to China Patent Application No. 2023109122412, filed on Jul. 22, 2023, the content of which is hereby incorporated by reference in its entirety.
The present disclosure belongs to the technical field of electronic cigarettes, and in particular, relates to a cartridge and an electronic cigarette having the cartridge.
Reloadable electronic cigarettes include a cigarette rod and a cartridge that is detachably connected to the cigarette rod. When the e-liquid in the cartridge is used up, the user can continue to use the cigarette rod by replacing the cartridge, which is more in line with the concept of environmental protection and saves resource. The cartridge is provided with an e-liquid storage cavity and an atomization chamber. The e-liquid storage cavity is used to store the e-liquid. The e-liquid in the e-liquid storage cavity can enter the atomization chamber through an e-liquid inlet hole, and then be heated and evaporated in the atomization chamber to form atomized aerosol. An air inlet hole is provided at the bottom of the cartridge. When the user uses the cartridge to inhale, the outside air is introduced through the air inlet hole, mixes with the atomized aerosol, and then passes through an aerosol outlet channel of the cartridge to reach a nozzle for the user to inhale.
However, such cartridge also has the following shortcomings. On the one hand, during the user's inhaling process, because the e-liquid in the e-liquid storage cavity enters the atomization chamber, the reduction in the amount of e-liquid in the e-liquid storage cavity will generate a negative pressure in the e-liquid storage cavity. Therefore, the e-liquid in the e-liquid storage cavity is difficult to enter the atomization chamber smoothly due to the negative pressure, causing the cartridge to dry-burn. On the other hand, after the user finishes inhaling, the outside air can pass through the nozzle, the aerosol outlet channel, the atomization chamber, and an e-liquid inlet channel, and eventually enter the e-liquid storage cavity. When the ambient pressure changes, the pressure inside the e-liquid storage cavity may increase, and then the e-liquid is forced into the e-liquid inlet channel and the atomization chamber, causing the e-liquid leakage; or the cartridge is stored in a high-temperature environment, the thermal expansion of the air in the e-liquid storage cavity will increase the pressure inside the e-liquid storage cavity, and then the e-liquid will be forced into the e-liquid inlet channel and atomization chamber, causing e-liquid leakage.

Referring to
It should be noted that the aerosol channel includes an atomizing tube 400 that generates atomized aerosol inside the cartridge 1 and an aerosol outlet tube 120 that allows the atomized aerosol to flow to the outside.
It should be noted that the self-deforming partition 300 being sealingly connected to at least one of the inner wall of the housing assembly and the outer wall of the aerosol channel, means that the self-deforming partition 300 may be sealingly connected only to the inner wall of the housing assembly such that the self-deforming partition 300, the inner wall of the housing assembly, and the outer wall of the aerosol channel enclose the e-liquid storage cavity 900; or, the self-deforming partition 300 may be sealingly connected only to the outer wall of the aerosol channel, such that the self-deforming partition 300 and the outer wall of the aerosol channel enclose the e-liquid storage cavity 900; or, a first end of the self-deforming partition 300 may be sealingly connected to the inner wall of the housing assembly, and a second end of the self-deforming partition 300 is sealingly connected to the outer wall of the aerosol channel, such that the self-deforming partition 300, the inner wall of the housing assembly, and the outer wall of the aerosol channel enclose the e-liquid storage cavity 900. The self-deforming partition 300 can collapse and deform toward the aerosol channel means that the self-deforming partition 300 can collapse toward the aerosol channel as the amount of the e-liquid decreases. During this process, the e-liquid storage cavity 900 shrinks and self-deforms, and at least a part of the self-deforming partition 300 becomes adjacent to the aerosol channel. In other words, the self-deforming partition 300 can collapse and deform toward the aerosol channel means that the self-deforming partition 300 can automatically reduce the volume of the e-liquid storage cavity 900 by the same amount according to the consumption amount of the e-liquid.
It should be noted that the e-liquid storage cavity 900 may be filled with e-liquid, and little or no gas is filled in the e-liquid storage cavity 900. As the e-liquid in the e-liquid storage cavity 900 is consumed, the self-deforming partition 300 collapses and deforms toward the aerosol channel, and thus the e-liquid storage cavity 900 shrinks and reduced its volume. During this process, no negative pressure will be generated in the e-liquid storage cavity 900, and the outside air will not enter the e-liquid storage cavity 900.
In the cartridge 1 according to the embodiment of the present disclosure, since the e-liquid storage cavity 900 is defined between the self-deforming partition 300 and the outer wall of the aerosol channel, and the self-deforming partition 300 can collapse and deform toward the aerosol channel as the amount of the e-liquid in the e-liquid storage cavity 900 decreases, when the amount of e-liquid in the e-liquid storage cavity 900 decreases, no negative pressure will be generated in the e-liquid storage cavity 900, such that the e-liquid in the e-liquid storage cavity 900 can smoothly enter the aerosol channel, and dry burning of the cartridge 1 can be avoided without providing a ventilation structure. In addition, since the self-deforming partition 300 collapses and deforms toward the aerosol channel as the amount of e-liquid decreases, the e-liquid storage cavity 900 is always filled with e-liquid, no negative pressure will be generated in the e-liquid storage cavity 900, and the outside air cannot enter the e-liquid storage cavity 900 through the aerosol channel and the e-liquid inlet channel 410. Therefore, even if the cartridge 1 is stored in a high-temperature environment or the ambient pressure outside the cartridge 1 changes, the pressure inside the e-liquid chamber 900 will not increase, thereby avoiding possible leakage of the e-liquid caused by the fact that the e-liquid is forced into the e-liquid inlet channel 410 and the aerosol channel. In addition, since outside air will not enter the e-liquid storage cavity 900, no bubble area will be generated in the e-liquid storage cavity 900, thereby preventing the bubble area from interfering with the e-liquid entering the aerosol channel through the e-liquid inlet channel 410.
In one embodiment, the e-liquid inlet channel 410 is configured to only allow the e-liquid to flow unidirectionally to the aerosol channel, and prevent the e-liquid in the aerosol channel from flowing reversely to the e-liquid storage cavity 900, such that the residual e-liquid and the atomized condensed liquid in the aerosol channel can be prevented from flowing back reversely to the e-liquid storage cavity through the e-liquid inlet channel 410, and it is also possible to prevent the air outside the cartridge 1 from entering the e-liquid storage cavity 900 through the nozzle portion 110, the aerosol channel, and the e-liquid inlet channel 410. In this way, the negative pressure can be prevented from being generated in the e-liquid storage cavity 900 after the air enters the e-liquid storage cavity 900 and when the amount of e-liquid in the e-liquid storage cavity 900 decreases.
As an example, by arranging a one-way valve or an elastic valve in the e-liquid inlet channel 410, the function of preventing the e-liquid in the aerosol channel from flowing reversely to the e-liquid storage cavity 900 is achieved. The arrangement and working principle of the one-way valve and elastic valve are common knowledge in the art, and which will not be described herein.
Moreover, since fluids such as residual e-liquid, liquor condensate, and air will not enter the e-liquid storage cavity, the self-deforming partition 300 can automatically collapse and deform toward the aerosol channel when the amount of e-liquid in the e-liquid storage cavity 900 decreases. In other words, the e-liquid inlet channel 410 of this embodiment provides a specific implementation for realizing the self-deforming partition 300 to have the automatic collapse and deformation function. Therefore, the cartridge 1 of this embodiment is not necessary to be provided with a ventilation hole 130 as described below on the housing assembly thereof, which reduces the processing steps of the housing assembly of the cartridge 1 and can also avoid dust and other pollutants in the external environment from contaminating and damage the self-deforming partition 300 through the ventilation hole 130.
Referring to
It should be understood that by providing the ventilation hole 130 on the housing assembly, the external atmospheric pressure can compress the outer wall of the self-deforming partition 300 through the ventilation hole 130. Therefore, when the amount of e-liquid in the e-liquid storage cavity 900 decreases, the self-deforming partition 300 can collapse toward the aerosol channel under the action of external atmospheric pressure, so that the pressure inside the e-liquid storage cavity 900 always maintains a balance with the external atmospheric pressure.
It should be noted that the number and shape of the ventilation holes 130 are not limited. Referring to
In an embodiment, a filter is provided in the ventilation hole 130. The filter only allows the air to pass through.
It should be understood that the filter can play a dustproof and protective role, preventing external dust, large particles or other pollutants from entering the housing assembly, thereby preventing dust, large particles and other pollutants from damaging or contaminating the self-deforming partition 300.
For example, the filter may be made from a semipermeable film, which is easily configured to allow only the air molecules to pass through, and prevent other particulate matter in the air from passing through.
Referring to
It should be noted that the air inlet gap 800 is configured to be able to be in communication with the outside of the housing assembly through the ventilation hole 130 even when the e-liquid storage cavity 900 is filled with e-liquid.
By providing the air inlet gap 800, the air outside the housing assembly can continuously enter the air inlet gap 800, so that the self-deforming partition 300 can always be subjected to the atmospheric pressure, and collapse and deform toward the aerosol channel during the consumption of e-liquid. As such, the internal pressure of the e-liquid storage cavity is kept in balance with the external atmospheric pressure. In addition, the provision of the air inlet gap 800 also avoids the situation where the self-deforming partition 300 may directly attach to the inner wall of the housing assembly and prevent the entry of outside air when the e-liquid storage cavity 900 is filled with e-liquid.
In an embodiment, the self-deforming partition 300 is made of elastic material.
It should be understood that when the amount of e-liquid in the e-liquid storage cavity 900 decreases, the self-deforming partition 300 made of elastic material can undergo elastic deformation to shrink toward the aerosol channel under the action of the external atmospheric pressure, that is, the self-deforming partition 300 can collapse towards the aerosol channel. On the contrary, during the process of filling e-liquid into the e-liquid storage cavity 900, as the amount of e-liquid in the e-liquid storage cavity 900 increases, the self-deforming partition 300 made of elastic material will be expanded until the e-liquid filling process is completed. During such e-liquid filling process, the e-liquid storage cavity 900 can always maintain in balance with the external atmospheric pressure.
In another embodiment, the self-deforming partition 300 is made of a flexible film. When the self-deforming partition 300 made of flexible film and the inner wall of the housing assembly or the outer wall of the aerosol channel jointly enclose the e-liquid storage cavity 900, as the amount of e-liquid in the e-liquid storage cavity 900 decreases, the flexible film can automatically shrink, that is, the self-deforming partition 300 can automatically collapse and deform toward the aerosol channel.
Specifically, the flexible film may be a rubber film or a plastic film. The plastic film can be one or more resin materials selected from the group consisting of polyethylene film (LDPE, HDPE, LLDPE, VLDPE, MPE), polypropylene film (CPP, BOPP), polyvinyl chloride film (PVC), etc., and which is not limited thereto.
In an embodiment, the self-deforming partition 300 is made of a plastic shell.
It should be noted that the plastic shell here is a soft plastic shell that can collapse and deform toward the aerosol channel as the amount of e-liquid in the e-liquid storage cavity 900 decreases, and does not include a rigid plastic shell that does not collapse and deform toward the aerosol channel.
Referring to
It should be noted that the sealing base 200 is a part of the housing assembly and is inserted into an opening of the housing 100. An outer wall of the sealing base 200 exposed inside the housing 100 is actually a part of the inner wall of the housing assembly.
The self-deforming partition 300, the outer wall of the sealing base 200, and the outer wall of the aerosol channel cooperatively enclose the e-liquid storage cavity 900, and the two ends of the self-deforming partition 300 are sealingly connected to the aerosol channel and the sealing base 200 respectively, thereby ensuring the e-liquid in the e-liquid storage cavity 900 can only flow to the aerosol channel through the e-liquid inlet channel 410 without leaking from connection portions of the self-deforming partition 300.
In an embodiment, the self-deforming partition 300 is made of silicone material, the housing 100 is made of rigid rubber, and the air inlet gap 800 is provided between the inner wall of the housing 100 and the self-deforming partition 300.
The silicone material is commercially available, and the self-deforming partition 300 made of silicone material has low production cost, and the manufacturing process of the self-deforming partition 300 is easy to implement. Moreover, the silicone material has good elastic deformation ability, so that the self-deforming partition 300 can collapse and deform toward the aerosol channel as the amount of e-liquid in the e-liquid storage cavity 900 decreases. In addition, the housing 100 made of rigid rubber is not easily deformed, so that the normal appearance shape of the cartridge 1 can be maintained and the use requirements of the cartridge 1 can be met. On the other hand, when the cartridge 1 is placed in a high-temperature environment, the housing 100 will deform due to the high temperature, causing the inner cavity of the housing 100 to shrink and deform. However, there is little shrinkage deformation of the housing 100 made of rigid rubber. The air inlet gap 800 can be provided to ensure that the housing 100 will not compress the self-deforming partition 300 during the deformation process of the housing 100, so as to prevent the self-deforming partition 300 from compressing the e-liquid in the e-liquid storage cavity 900, and prevent possible leakage of e-liquid. It should be noted that the “high temperature” here refers to the relatively high ambient temperature in which the cartridge 1 is used in some areas and in high-temperature weather conditions.
In an embodiment, a wall thickness of the self-deforming partition 300 is in a range from about 0.1 mm to about 0.4 mm. Setting the wall thickness below 0.4 mm can make the self-deforming partition 300 more prone to elastic deformation, so that it can ensure that the self-deforming partition 300 is more capable of collapsing and deforming toward the aerosol channel as the amount of e-liquid in the e-liquid storage cavity 900 decreases. Setting the wall thickness to greater than 0.1 mm can prevent the self-deforming partition 300 from easily breaking, and self-deforming partitions with the wall thickness greater than 0.1 mm are also easy to process and manufacture.
In an embodiment, the air inlet gap between the inner wall of the housing 100 and the self-deforming partition 300 is not less than 0.2 mm. For the housing 100 made of rigid rubber and the self-deforming partition 300 made of silicone material, the air inlet gap of not less than 0.2 mm can ensure that the housing 100 will not compress the self-deforming partition 300 during the deformation process of the housing 100 in a high temperature environment.
In this embodiment, the wall thickness of the self-deforming partition 300 is 0.3 mm, the air inlet gap between the inner wall of the housing 100 and the self-deforming partition 300 is 0.3 mm, and the housing 100 is made of polycarbonate (PC) and poly(1,4-cyclohexylene dimethylene terephthalate Glycol) (PCTG).
Referring to
It should be understood that both the first sealing ring 310 and the second sealing ring 320 are provided on the self-deforming partition 300, and are connected to the aerosol outlet tube 120 and the atomizing tube 400 respectively that form the aerosol channel, so that the self-deforming partition 300 can be sealed at the connection portion between the self-deforming partition 300 and the aerosol outlet tube 120, and the connection portion between the self-deforming partition 300 and the atomizing tube 400, thereby achieving double sealing between the self-deforming partition 300 and the aerosol channel, which can prevent the e-liquid in the e-liquid storage cavity 900 from leaking from the connection portion between the self-deforming partition 300 and the atomizing tube 120 or from the connection portion between the self-deforming partition 300 and the atomizing tube 400.
In an embodiment, an annular protrusion 330 is provided on one of the first end of the self-deforming partition 300 surrounding the sealing base 200 and the outer wall of the sealing base 200, and an annular groove is provided on the other of the first end of the self-deforming partition 300 surrounding the sealing base 200 and the outer wall of the sealing base 200. The annular protrusion 330 is assembled in the annular groove with an interference fit.
It should be understood that by assembling the annular protrusion 330 in the annular groove with an interference fit, the connection portion between the self-deforming partition 300 and the sealing base 200 can be ensured to remain sealed, thereby preventing the e-liquid in the e-liquid storage cavity 900 from leaking from the connection portion between the self-deforming partition 300 and the sealing base 200.
Referring to
In other embodiments, a third sealing ring is provided on the first end of the self-deforming partition 300 surrounding the sealing base 200. The third sealing ring abuts against the outer wall of the sealing base 200. It should be understood that the third sealing ring is configured to seal a gap between the self-deforming partition 300 and the outer wall of the sealing base 200.
Referring to
The main body, the first sealing ring 310, the second sealing ring 320, and the annular protrusion 330 are processed through the double injection molding process, so that the main body, the first sealing ring 310, the second sealing ring 320, and the annular protrusion 330 can be made from different types of plastic materials separately. By reasonably selecting the types of plastic material, the main body can have the ability to collapse and deform toward the aerosol channel as the amount of e-liquid in the e-liquid 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.
Referring to
It should be understood that by arranging the plug-in terminal 360 and the avoidance groove 370, the space inside the housing 100 can be fully utilized to maximize the volume of the e-liquid storage cavity 900, and the self-deforming partition 300 can be easily sleeved on the aerosol outlet tube 120. The first sealing ring 310 and the second sealing ring 320 can prevent the gaps from forming among the aerosol outlet tube 120, the atomizing tube 400, and the self-deforming partition 300. The inner diameter of the atomizing tube 400 is greater than that of the aerosol outlet tube 120, and the aerosol outlet tube 120 extends into the atomizing tube 400 and is in communication with the atomizing tube 400, so that the atomized gas in the atomizing tube 400 can only flow outward to the nozzle portion 110 through the aerosol outlet tube 120, but not easy to leak to other portions.
Referring to
In an embodiment, an end surface of the atomizing tube 400 adjacent to the aerosol outlet tube 120 abuts against the first sealing ring 310.
It should be understood that by arranging the end of the atomizing tube 400 adjacent to the aerosol outlet tube 120 to abut against the first sealing ring 310, the gap between the atomizing tube 400 and the aerosol outlet tube 120 can be sealed by the first sealing ring 310, thereby preventing the e-liquid storage cavity 900 from being in communication with the aerosol channel through the gap between the second sealing ring 320 and the outer wall of the atomizing tube 400.
In an embodiment, the housing 100 and the self-deforming partition 300 are made of transparent material. The e-liquid stored in the e-liquid storage cavity 900 is generally a colored liquid. By configuring the housing 100 and the self-deforming partition 300 to both be transparent, it is convenient for the user to observe the consumption of e-liquid in the e-liquid storage cavity 900 and the deformation process of the self-deforming partition 300.

In some other embodiments, the atomizing assembly 500 can also be provided directly below an opening at one end of the atomizing tube 400, as long as it is ensured that the e-liquid stored in the e-liquid storage cavity 900 can reach the atomizing assembly 500 through the e-liquid inlet channel 410, and the atomized gas generated by converting the e-liquid by the atomizing assembly 500 can enter the atomizing tube 400.
Referring to
In this embodiment, the atomizing assembly 500 includes an atomizing bracket 510 mounted in the atomizing tube 400, an atomizing core 520, and a heating wire connected to the atomizing core 520. The e-liquid in the e-liquid storage cavity 900 enters the atomizing tube 400 through the e-liquid inlet channel 410, and then passes through the atomizing bracket 510 to reach the atomizing core 520, where the e-liquid is heated and atomized into aerosol by the heating wire.
Referring to
Referring to
It should be understood that by arranging the fifth sealing ring 700, the sealing effect at the connection portion between the housing 100 and the sealing base 200 is ensured, thereby preventing outside air from entering the air inlet gap 800 through the ventilation hole 130 and leaking from the connection portion between the housing 100 and the sealing base 200, thereby avoiding the possible situation where the self-deforming partition 300 cannot collapse toward the aerosol channel.
In addition, an embodiment of the present disclosure further provides an electronic cigarette. The electronic cigarette includes the cartridge 1 of the above embodiments and a cigarette rod. The cartridge 1 is electrically connected to the cigarette rod. The cartridge 1 and the cigarette rod is an integral member. Alternatively, the cartridge 1 is detachably mounted on the cigarette rod.
The electronic cigarette according to the embodiment of the present disclosure includes the above-mentioned cartridge 1, and thus can also prevent the cartridge 1 from dry burning and prevent the leakage of e-liquid.
In the foregoing cartridge for the electronic cigarette, since the e-liquid storage cavity is defined between the self-deforming partition and the outer wall of the aerosol channel, and the self-deforming partition can collapse and deform toward the aerosol channel as the amount of the e-liquid in the e-liquid storage cavity decreases. When the amount of e-liquid in the e-liquid storage cavity decreases, no negative pressure will be generated in the e-liquid storage cavity, such that the e-liquid in the e-liquid storage cavity can smoothly enter the aerosol channel, and dry burning of the cartridge can be avoided without providing a ventilation structure. In addition, since the self-deforming partition collapses and deforms toward the aerosol channel as the amount of e-liquid decreases, the e-liquid storage cavity is always filled with e-liquid, no negative pressure will be generated in the e-liquid storage cavity, and the outside air cannot enter the e-liquid storage cavity through the aerosol channel and the e-liquid inlet channel. Therefore, even if the cartridge is stored in a high-temperature environment or the ambient pressure outside the cartridge changes, the pressure inside the e-liquid chamber will not increase, thereby avoiding possible leakage of the e-liquid caused by the fact that the e-liquid is forced into the e-liquid inlet channel and the aerosol channel. In addition, since outside air will not enter the e-liquid storage cavity, no bubble area will be generated in the e-liquid storage cavity, thereby preventing the bubble area from interfering with the e-liquid entering the aerosol channel through the e-liquid inlet channel.
The electronic cigarette includes the cartridge according to any one of embodiments of the present disclosure, and thus can also prevent the cartridge from dry burning and prevent the leakage of e-liquid.
The cartridge and the electronic cigarette having the same can address the technical problems that cartridges of existing electronic cigarettes are prone to dry burning and e-liquid leakage.

The foregoing descriptions are merely specific embodiments of the present disclosure, but are not intended to limit the protection scope of the present disclosure.
