Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, and specifically relates to a cartridge structure. Background Art

[0002] An electronic cigarette usually consists of a cartridge and a cigarette rod that provides electrical energy to the cartridge. An air flow channel and a negative pressure channel communicating with the inhalation channel of the cartridge are formed in the cigarette rod. The other end of the air flow channel communicates with the outside, and the other end of the negative pressure channel communicates with a receiving cavity where a microphone is installed. When the user inhales through the inhalation channel of the cartridge, the air in the negative pressure channel and the receiving cavity communicating with the negative pressure channel is sucked away, and the inside of the receiving cavity is in a negative pressure state, which will trigger the microphone. When the microphone is triggered, it conducts the cigarette rod and the cartridge to convert the e-liquid contained in the cartridge into aerosol for the user to inhale.

[0003] In the related art, some cartridges are disposable consumables with a small capacity, so they can only provide a short usage time for users. Moreover, this cartridge structure does not support users to refill the e-liquid repeatedly. Therefore, when the e-liquid in the cartridge is exhausted, a new cartridge needs to be replaced to continue using. This leads to the need for users to carry multiple cartridges when going out for a long time, thus reducing the portability of the electronic cigarette. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a cartridge structure to solve the problems that the cartridges in the related art do not support users to refill the e-liquid repeatedly and have poor portability.

Specific implementation manners

[0025] Next, the solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0026] It should be noted that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. In addition, the descriptions involving "first", "second", etc. in the embodiments of the present utility model are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features.

[0027] In view of the technical defects in the related art, this embodiment provides a cartridge structure. As Figure 1 shown, the cartridge structure of this embodiment includes a main body part 1 and an expansion part 2 that can be spliced and used with the main body part 1.

[0028] Combined Figure 2 shown, a mouthpiece 3 is convexly provided on the outer side of the main body part 1 of this embodiment, and a first oil chamber 7 for containing e-liquid is provided inside the main body part 1. An atomizing component 5 is also provided in the first oil chamber 7. The atomizing component 5 can receive the e-liquid in the first oil chamber 7 and convert the e-liquid into absorbable aerosol. The atomizing component 5 is also communicated with the mouthpiece 3, so that the user can inhale the aerosol generated by the atomizing component 5 through the mouthpiece 3.

[0029] Continue to refer toFigure 2 As shown, a plug hole communicating with the first oil chamber 7 is also provided on the main body portion 1, and a seal member 42 for sealing the plug hole is embedded in the plug hole. That is to say, when the seal member 42 is embedded in the plug hole, fluids such as gas or liquid cannot pass through the plug hole.

[0030] Among them, a reset member 41 is provided between the seal member 42 and the inner wall of the first oil chamber 7 opposite to the seal member 42. Both ends of the reset member 41 are respectively connected to the seal member 42 and the inner wall of the first oil chamber 7. A oil guiding through groove 91 and an oil guiding convex member 9 are provided on the side of the seal member 42 facing away from the reset member 41.

[0031] It should be noted that the relative positions between the oil guiding through groove 91 and the oil guiding convex member 9 can have various arrangement forms according to actual needs. For example: the oil guiding convex member 9 can be located outside the oil guiding through groove 91, or the oil guiding convex member 9 can also be located on the bottom of the oil guiding through groove 91. It should be noted that when the oil guiding convex member 9 is located on the bottom of the oil guiding through groove 91, the oil guiding convex member 9 cannot block the passage of the oil guiding through groove 91. In some alternative examples, the number of the oil guiding convex members 9 and the oil guiding through grooves 91 can be multiple. For example: multiple oil guiding convex members 9 and oil guiding through grooves 91 are arranged alternately, or an arrangement method can also be adopted where a part of the interval of the oil guiding through groove 91 is located between two oil guiding convex members 9.

[0032] Optionally, in this embodiment, at least a part of the oil guiding through groove 91 is formed along the radial direction of the seal member 42. For example: the entire interval of the oil guiding through groove 91 is formed along the radial direction of the seal member 42. That is to say, when observing the oil guiding through groove 91 in the axial direction of the seal member 42, the oil guiding through groove 91 presents a "one" character shape; another example: when observing the oil guiding through groove 91 in the axial direction of the seal member 42, the oil guiding through groove 91 can also present a "cross" character shape, or a "rice" character shape, but not limited thereto.

[0033] Continue to refer to Figure 2 As shown, a second oil chamber 23 for accommodating the extended e-liquid is provided in the extended portion 2 of this embodiment. An insertion pipe 21 communicating with the second oil chamber 23 is provided outside the extended portion 2, and the pipe orifice of the insertion pipe 21 is sealed by a sealing film 24 to prevent the extended e-liquid from leaking outwards.

[0034] It has been described above that the main body portion 1 and the extended portion 2 of this embodiment can be spliced and used. Specifically, in combination with Figure 3 and Figure 4 As shown, the main body portion 1 and the extended portion 2 of this embodiment can be spliced with each other under an external force.

[0035] Under the action of external force, the plug-in tube 21 is plugged into the plug-in hole to splice the main body 1 and the expansion part 2. As the plug-in tube 21 is plugged in, the sealing film 24 sealing the tube opening of the plug-in tube 21 first contacts the oil guide protrusion 9 and is punctured by the oil guide protrusion 9. Then, under the action of external force, the plug-in tube 21 pushes the sealing member 42 out of the plug-in hole.

[0036] Since a reset member 41 is provided between the sealing member 42 and the inner wall of the first oil chamber 7 opposite to the sealing member 42, the sealing member 42 pushed out of the plug hole abuts against the plug tube 21 under the reset action of the reset member 41. In addition, an oil guide groove 91 is provided on the side of the sealing member 42 facing away from the reset member 41. Therefore, when the sealing film 24 is punctured by the oil guide protrusion 9, the first oil chamber 7 and the second oil chamber 23 are connected to each other through the oil guide groove 91, so that the expanded smoke oil in the second oil chamber 23 can flow into the first oil chamber 7.

[0037] In summary, after adopting the cartridge structure of this embodiment, when the electronic cigarette needs to be used for a long time, the expansion part 2 and the main body 1 can be spliced ​​to form a large-capacity cartridge, thereby meeting the user's long-term use needs. Moreover, after the expansion part 2 and the main body 1 are spliced, the overall capacity of the cartridge becomes larger, so it is helpful to reduce the number of cartridges that the user carries when going out, thereby improving the portability of the electronic cigarette. In addition, in addition to the oil, the second oil chamber 23 can also be filled with additives such as flavors, thereby improving the taste of the oil.

[0038] In some embodiments, Figure 2 and Figure 4 As shown, the main body 1 includes a first shell and a first sealing seat 6 detachably connected to the first shell, and the first shell and the first sealing seat 6 enclose a first oil chamber 7, thereby facilitating the assembly of the main body 1. According to actual needs, a first oil filling hole for injecting smoke oil can also be provided on the first sealing seat 6, and a first sealing plug is embedded in the first oil filling hole. Among them, the first sealing seat 6 is provided with a first mounting groove 4 on the side facing the first shell, and the plug-in hole is provided in the first shell and arranged opposite to the notch of the first mounting groove 4. The reset member 41 is located in the first mounting groove 4, one end of the reset member 41 is connected to the sealing member 42, and the other end of the reset member 41 is connected to the bottom of the first mounting groove 4, thereby facilitating the assembly operation of the reset member 41.

[0039] In an optional example, a positioning column is protruding from the bottom of the first installation groove 4, and the reset member 41 is a compression spring. One end of the reset member 41 is sleeved on the positioning column to further stabilize the assembly state of the reset member 41.

[0040] In some embodiments, Figure 5As shown, the expansion part 2 includes a second housing and a second seal seat 22 detachably connected to the second housing. The second housing and the second seal seat 22 enclose a second oil chamber 23. The insertion pipe 21 is provided on the side of the second seal seat 22 facing away from the second housing. According to actual needs, a second oil injection hole for injecting expansion e-liquid may also be provided on the second seal seat 22, and a second seal plug is embedded in the second oil injection hole.

[0041] In some embodiments, in order to improve the flatness of the entire cartridge structure after splicing the main body part 1 and the expansion part 2, the main body part 1 forms a step, and the expansion part 2 has a profiling surface corresponding to the step. A second installation groove 8 is formed on one surface of the step. The insertion hole is opened at the bottom of the second installation groove 8. The insertion pipe 21 is arranged on the side of the profiling surface facing the second installation groove 8 when the main body part 1 and the expansion part 2 are spliced.

[0042] Among them, when the main body part 1 and the expansion part 2 are spliced with each other, a part of the expansion part 2 is accommodated in the second installation groove 8. A detachable connection is provided between the outer wall of the part of the expansion part 2 accommodated in the second installation groove 8 and the groove wall of the second installation groove 8 to facilitate the user to easily splice or separate the main body part 1 and the expansion part 2.

[0043] In some embodiments, as Figure 6 shown, the atomization component 5 includes an atomization tube 52 disposed in the first oil chamber 7 and an atomization core 51 disposed in the atomization tube 52. Exemplarily, as Figure 4 shown, when arranging the atomization tube 52, the axial direction of the atomization tube 52 is parallel to the axial direction of the insertion hole. However, according to actual needs, the arrangement direction of the atomization tube 52 can be other directions, and no further examples are given here.

[0044] As Figure 6 shown, an oil inlet hole 53 is opened on the atomization tube 52. The e-liquid in the first oil chamber 7 flows into the lumen of the atomization tube 52 through the oil inlet hole 53 and is converted into aerosol by the atomization core 51.

[0045] The above are only partial or preferred embodiments of the present invention. Whether in terms of text or drawings, the scope of protection of the present invention cannot be limited thereby. All equivalent structural transformations made under the overall concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields are included in the scope of protection of the present invention.
