Description

Technical Field

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

[0002] An electronic cigarette generally 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 liquid storage cavity equipped with a microphone head. When the user inhales through the inhalation channel of the cartridge, the air in the negative pressure channel and the liquid storage cavity communicating with the negative pressure channel is drawn away, and the inside of the liquid storage cavity is in a negative pressure state, thereby triggering the microphone head. When the microphone head 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, in order to prevent the problem of dry burning caused by insufficient e-liquid wetting of the atomization core when a new cartridge is used for the first time, e-liquid is pre-injected into the wicking cotton of the atomization core. However, if the airtightness of the cartridge packaging is insufficient, the pre-injected e-liquid will contact with air and deteriorate, thus affecting the product quality. Summary of the Utility Model

[0004] The main purpose of the utility model is to propose a cartridge structure to improve the reliability of the cartridge.

[0005] To achieve the above object, the utility model proposes a cartridge structure, which includes a main body part and a dispensing box that can be plugged into the main body part for use;

[0006] The dispensing box includes a first housing for accommodating a first matrix, and a sealing film for sealing the open end of the first housing;

[0007] A liquid storage cavity for accommodating a second matrix is provided in the main body part. A plugging hole for plugging the dispensing box is formed in the main body part. The plugging hole communicates with the liquid storage cavity. A sealing plug for sealing the plugging hole is embedded in the plugging hole. A convex part is provided on one side of the sealing plug facing the insertion side of the dispensing box;

[0008] Wherein, under the action of an external force, the dispensing box can be plugged into the plugging hole; during the process of plugging the dispensing box into the plugging hole, the sealing film is punctured by the convex part, and then the first housing pushes the sealing plug out of the plugging hole, so that the inner cavity of the first housing and the liquid storage cavity communicate with each other.

[0009] In some embodiments, the main body part includes a second housing and a sealing seat detachably connected to the second housing. The second housing and the sealing seat enclose to form the liquid storage cavity. The plugging hole is formed in the second housing and is arranged opposite to the sealing seat.

[0010] In some embodiments, a slot is formed on one side of the sealing seat facing the sealing plug. A plugging rod is provided on one side of the sealing plug facing the sealing seat. A guiding portion is provided at the free end of the plugging rod, and the guiding portion is plugged into the slot. When the sealing plug is pushed out of the plugging hole by the first housing, the plugging rod is plugged into the slot under the guiding action of the guiding portion.

[0011] In some embodiments, the plugging rod is detachably connected to the sealing plug.

[0012] In some embodiments, the protruding member is detachably connected to the sealing plug.

[0013] In some embodiments, a suction nozzle is provided on the outer side of the main body portion. An atomization tube communicating with the suction nozzle is arranged in the liquid storage cavity. An atomization core is arranged in the atomization tube. An oil inlet hole communicating with the liquid storage cavity is formed on the atomization tube. The oil inlet hole is used to supply the second matrix or a mixed matrix of the second matrix and the first matrix to the atomization core.

[0014] Compared with the related art, the beneficial effects of the present utility model are as follows:

[0015] Through the insertion and matching between the dispensing box and the main body portion, the sealing plug is pushed into the liquid storage cavity by the dispensing box. Since the sealing plug occupies a part of the space in the liquid storage cavity, the internal pressure in the liquid storage cavity increases. Therefore, when the atomization cavity of the atomization component and the liquid storage cavity are communicated with each other through the oil inlet hole, under the action of the internal pressure in the liquid storage cavity, the matrix in the liquid storage cavity automatically flows into the atomization cavity through the oil inlet hole to infiltrate the oil guiding cotton of the atomization core.

[0016] In summary, when the cartridge structure of the present utility model is shipped, it is not necessary to pre-inject e-liquid into the oil guiding cotton of the atomization core, which is beneficial to maintaining the product quality of the cartridge. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation

[0022] The following will clearly and completely describe the solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] 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 invention 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.

[0024] In addition, a "matrix" refers to a mixture or auxiliary substance that can be atomized into an aerosol in whole or in part by an electronic device or a similar device. The matrix can be an e-cigarette liquid in liquid form, a medical drug, a skin care lotion, etc. By atomizing these matrices, an aerosol that can be inhaled or absorbed can be provided for users.

[0025] To address the deficiencies in the related art, this embodiment provides a cartridge structure, as Figure 1 shown, the cartridge structure of this embodiment includes a main body 100 and a dispensing box 200 that can be inserted and used with the main body 100. Among them, as Figure 3 shown, the dispensing box 200 includes a first housing 210 for accommodating a first matrix, and a sealing film 220 for sealing the open end of the first housing 210. Exemplarily, the first housing 210 can be in a cylindrical shape, and the sealing film 220 can be made of materials such as tin foil or aluminum-plastic film.

[0026] As Figure 3 shown, a liquid storage cavity 140 for accommodating a second matrix is provided in the main body 100, and an insertion hole 130 for inserting the dispensing box 200 is formed on the main body 100, and the insertion hole 130 is communicated with the liquid storage cavity 140. Among them, a sealing plug 300 for sealing the insertion hole 130 is embedded in the insertion hole 130, that is, when the sealing plug 300 is embedded in the insertion hole 130, fluids such as gas or liquid cannot pass through the insertion hole 130.

[0027] On one side of the sealing plug 300 facing the insertion side of the dispensing box 200, there is a protruding member 310. In addition, a suction nozzle 400 is provided on the outer side of the main body 100, and an atomizing member is also arranged in the liquid storage cavity 140. The atomizing member includes an atomizing tube 510 communicating with the suction nozzle 400 and an atomizing core 520 arranged in the atomizing tube 510. The lumen of the atomizing tube 510 is an atomizing cavity, and the atomizing core 520 is used to atomize the matrix flowing into the atomizing cavity. In order to enable the matrix to flow into the atomizing cavity, an oil inlet hole (not shown in the figure) communicating with the liquid storage cavity 140 is provided on the atomizing tube 510. When arranging the atomizing tube 510, the axis of the atomizing tube 510 is parallel to the axis of the insertion hole 130. However, according to actual needs, the arrangement direction of the atomizing tube 510 can be other directions, and no examples will be given one by one here.

[0028] Continuing to combine Figures 2 to 4b As shown, the main body 100 and the dispensing box 200 of this embodiment can be connected to each other under an external force. As Figure 4a shown, under an external force, the dispensing box 200 can be inserted into the insertion hole 130. During the process of the dispensing box 200 being inserted into the insertion hole 130, the sealing film 220 first contacts the protruding member 310 and is punctured by the protruding member 310. After that, as Figure 4b shown, the dispensing box 200 further extends into the insertion hole 130 under an external force, so that the first housing 210 abuts against the sealing plug 300 and pushes the sealing plug 300 out of the insertion hole 130, thereby enabling the inner cavity of the first housing 210 and the liquid storage cavity 140 to communicate with each other.

[0029] When the dispensing box 200 is connected to the main body 100, since the inner cavity of the first housing 210 and the liquid storage cavity 140 communicate with each other, the first matrix in the dispensing box 200 and the second matrix in the liquid storage cavity 140 are mixed with each other. The mixed matrix of the first matrix and the second matrix flows into the atomizing core 520 through the oil inlet hole, so that the user can inhale the aerosol transformed from the mixed matrix. In order to improve the taste of the aerosol, the first matrix can be an additive such as essence, but not limited thereto.

[0030] In the cartridge structure of this embodiment, through the insertion and matching between the dispensing box 200 and the main body 100, the sealing plug 300 is pushed into the liquid storage cavity 140 by the dispensing box 200.

[0031] When the sealing plug 300 is pushed into the liquid storage cavity 140 by the dispensing box 200, the sealing plug 300 occupies a part of the space in the liquid storage cavity 140, so the internal pressure of the liquid storage cavity 140 increases. Therefore, when the atomizing cavity of the atomizing member and the liquid storage cavity 140 communicate with each other through the oil inlet hole, under the action of the internal pressure of the liquid storage cavity 140, the mixed matrix of the first matrix and the second matrix in the liquid storage cavity 140 automatically flows into the atomizing cavity through the oil inlet hole to soak the oil guiding cotton of the atomizing core 520.

[0032] In summary, when the cartridge structure of the present utility model is shipped, it is not necessary to pre-inject e-liquid into the wicking cotton of the atomization core 520. After the user receives the cartridge structure of this embodiment, connecting the main body portion 100 and the dispensing box 200 can wet part of the matrix in the main body portion 100 to the atomization core 520, so that the matrix can be normally heated, reducing the possibility of dry burning of the atomization core 520.

[0033] In some embodiments, as Figure 3 shown, the main body portion 100 includes a second housing 110 and a sealing seat 120 detachably connected to the second housing 110. The second housing 110 and the sealing seat 120 enclose a liquid storage cavity 140, facilitating the assembly of the main body portion 100. According to actual needs, an oil injection hole for injecting the second matrix may be provided on the sealing seat 120, and a sealing cover is embedded in the oil injection hole. Among them, the insertion hole 130 is opened in the second housing 110 and is arranged opposite to the sealing seat 120.

[0034] In some embodiments, as Figure 3 shown, a slot 121 is provided on one side of the sealing seat 120 facing the sealing plug 300. A plugging rod 320 is provided on one side of the sealing plug 300 facing the sealing seat 120, and a guiding portion 321 is provided at the free end of the plugging rod 320. The guiding portion 321 is plugged into the slot 121. Among them, as Figure 4a and Figure 4b shown, when the sealing plug 300 is pushed out of the insertion hole 130 by the first housing 210, the plugging rod 320 is plugged into the slot 121 under the guiding action of the guiding portion 321 to prevent the sealing plug 300 that has disengaged from the insertion hole 130 from moving randomly in the liquid storage cavity 140.

[0035] In some alternative examples, according to actual needs, the plugging rod 320 is detachably connected to the sealing plug 300, for example: snap connection or threaded connection. Of course, the protruding member 310 and the sealing plug 300 can also be detachably connected, facilitating assembly.

[0036] The above are only partial or preferred embodiments of the present utility model. Neither the text nor the drawings can limit the scope of protection of the present utility model. Any equivalent structural transformation made using the content of the specification and drawings of the present utility model under the overall concept of the present utility model, or any direct / indirect application in other related technical fields is included in the scope of protection of the present utility model.
