Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, specifically to a cigarette cartridge and an electronic atomization device. Background Technology

[0002] Electronic atomizing devices, also known as e-cigarettes, are electronic products that generate an aerosol by heating and atomizing e-liquid for inhalation. Electronic atomizing devices mainly consist of a cartridge (also called an atomizer) and a power supply system. The atomizer includes an e-liquid tank and a coil. Multi-tank (such as dual-tank or triple-tank) atomizers can store and atomize various e-liquids, thus satisfying the smoking experience of different flavors.

[0003] However, current multi-tank atomizers have separate vapor exit channels for each tank, resulting in a complex structure and increased manufacturing costs. Furthermore, the aerosols produced by each tank are inhaled through their respective exit channels. When users inhale two different flavors of e-liquid, the two aerosols need to blend in the mouth, leading to poor flavor fusion and negatively impacting the vaping experience of mixed flavors.

Detailed Implementation

[0047] The embodiments of this application will be described below. It should be noted that, in order to provide a concise description of these embodiments, this specification cannot provide a detailed description of all features of the actual embodiments. It should be understood that, in the actual implementation of any embodiment, changes may occur from one embodiment to another to achieve specific objectives. Furthermore, it is also understood that, although the efforts made in this development process may be complex and lengthy, for those skilled in the art related to the content of this application, some design, manufacturing, or production modifications based on the technical content disclosed in this application are merely conventional technical means and should not be construed as insufficient content of this application.

[0048] like Figures 1-6 As shown, the e-cigarette cartridge provided in this embodiment has at least two oil tanks 11 and a smoke outlet channel 31. Each oil tank 11 is connected to an atomization channel 23, and an atomization core 5 is provided in the atomization channel 23. All atomization channels 23 are connected to the smoke outlet channel 31.

[0049] When the cartridge is working, the e-liquid in each of the at least two oil tanks 11 flows into the atomization channel 23, and the aerosol generated after being atomized by the atomizing core 5 is inhaled into the mouth through the same smoke outlet channel 31.

[0050] All e-liquid tanks 11 share a single smoke outlet channel 31, reducing the number of smoke outlet channels 31, thus simplifying the structure and lowering manufacturing costs. Furthermore, when a user inhales two flavored e-liquids, the two aerosols begin to blend after entering the same smoke outlet channel 31, extending the blending path and improving the flavor fusion effect, thereby enhancing the vaping experience of mixed flavors.

[0051] The aforementioned at least two oil tanks 11 can be two oil tanks 11, three oil tanks 11, or two or more other numbers of oil tanks 11, thereby satisfying the vaping experience of at least two e-liquid flavors.

[0052] In some embodiments, the e-cigarette cartridge includes an oil cup 1, which has an internal oil storage chamber, a partition 12, and an exhaust pipe 3. The central hole of the exhaust pipe 3 forms an exhaust channel 31. The partition 12 seals and divides the oil storage chamber into at least two oil compartments 11. One end of the oil cup 1 has an opening. A sealing assembly 2 is used to close the opening, and an atomization channel 23 is disposed on the sealing assembly 2. The e-cigarette cartridge consists of an oil cup 1 and a sealing assembly 2, as shown below. Figures 3-6 As shown; the oil storage chamber of oil cup 1 is divided into at least two oil compartments 11 by partition 12, and the central hole of the smoke outlet 3 forms a smoke outlet channel 31, as shown. Figures 7-10 As shown. During processing, the partition 12 and the smoke outlet 3 can be integrally formed with the oil cup 1, which facilitates processing and can further reduce manufacturing costs; moreover, no assembly is required, saving assembly costs. The partition 12 and the smoke outlet 3 can also be subsequently fixed inside the oil cup 1 by means of heat fusion or bonding.

[0053] Optionally, the partition 12 can divide the oil storage chamber of the oil cup 1 into two oil compartments 11, three oil compartments 11, or two or more other numbers of oil compartments 11, thereby satisfying the vaping experience of various e-liquid flavors.

[0054] The sealing component 2 is detachably fixed to the opening of the oil cup 1 for easy installation and removal. For example, as shown... Figure 5As shown, the sealing component 2 and the oil cup 1 are fixedly connected by a snap-fit ​​structure. The snap-fit ​​structure includes two sets: one set includes a first snap-fit ​​protrusion on the outer circumferential surface of the sealing component 2's internal portion within the opening, and a snap-fit ​​groove on the inner wall of the oil cup 1, with the first snap-fit ​​protrusion snapping into the groove; the other set includes a snap-fit ​​hole on the circumferential wall of the outer cover portion of the sealing component 2 covering the oil cup 1, and a second snap-fit ​​protrusion on the outer wall of the oil cup 1, with the second snap-fit ​​protrusion snapping into the snap-fit ​​hole. This double snap-fit ​​design improves the connection strength between the sealing component 2 and the oil cup 1, thereby enhancing connection reliability.

[0055] Optionally, the oil cup 1 can be made of plastic, which is lightweight, easy to carry, and inexpensive. The oil cup 1 can also be made of other rigid and non-deformable materials, such as stainless steel or high-temperature resistant glass, as long as it does not chemically react with e-liquid, is non-toxic and harmless to the human body, and can store e-liquid and support the sealing component 2.

[0056] The outer cover of the sealing component 2 over the oil cup 1 can be made of iron, which provides good rigidity and structural reliability. Alternatively, the outer cover can be made of plastic, stainless steel, or other materials.

[0057] In some embodiments, the smoke outlet 3 is positioned along the axis of the oil cup 1; and / or the smoke outlet 3 is positioned on the partition 12. In this way, the smoke outlet 3 can be positioned along the axis of the oil cup 1, with the smoke outlet channel 31 located at the center of the oil cup 1, facilitating communication between all atomizing channels 23 and the smoke outlet channel 31. Alternatively, the smoke outlet 3 can be positioned on the partition 12, which can be integrally formed with the smoke outlet 3, simplifying the structure and reducing manufacturing costs.

[0058] Preferred, such as Figures 8-9 As shown, the smoke outlet 3 is located at the axial position of the oil cup 1 and is mounted on the partition 12. The partition 12 passes through the axial position of the oil cup 1, making it easier to separate different oil chambers 11 of the same size. For example, the partition 12 is located at the center of the length direction of the oil cup 1 and extends along the width direction of the oil cup 1, sealing and dividing the oil storage chamber of the oil cup 1 into two oil chambers 11, left and right.

[0059] In some embodiments, the sealing member is provided with at least two transition oil chambers 21, each corresponding to an oil reservoir 11, and the transition oil chambers 21 connect the oil reservoir 11 and the atomizing channel 23. Figure 4As shown. During operation, the e-liquid in each oil tank 11 first flows into the transition oil chamber 21 for buffering, and then flows into the atomization channel 23. After being atomized by the atomizing coil 5, it produces an aerosol. This separates the oil filling and atomization of the oil tank 11, simplifying the layout and saving manufacturing costs. In addition, the transition oil chamber 21 serves as an intermediate channel connecting the oil tank 11 and the atomization channel 23. The atomization channel 23 can be positioned close to the smoke outlet channel 31, facilitating the entry of the aerosol generated by the atomization in the atomization channel 23 into the smoke outlet channel 31, thus improving the vaping experience.

[0060] In some embodiments, a blocking structure is provided between the transition oil chamber 21 and the oil tank 11. The blocking structure includes an oil passage 43a for the e-liquid in the oil tank 11 to flow into the transition oil chamber 21 and a blocking part to prevent the e-liquid in the transition oil chamber 21 from flowing back into the oil tank 11. During operation, the e-liquid in each oil tank 11 flows into the transition oil chamber 21 through the oil passage 43a of the blocking structure for buffering, and then flows into the atomization channel 23. In addition, when the user places the electronic atomizing device upside down, tilted, or flat, the blocking part of the blocking structure can prevent the e-liquid in the transition oil chamber 21 from flowing back into the oil tank 11; this avoids the atomizing coil 5 from burning due to the lack of e-liquid in the transition oil chamber 21, thus optimizing the user experience. Optionally, the blocking structure is an oil-sealing baffle with a hollow structure, through which the oil passage 43a is formed.

[0061] In some embodiments, the sealing assembly 2 includes at least two first sealing portions 22, which are inserted into the oil tank 11 in a one-to-one correspondence; a second sealing portion for sealing contact with the partition 12, the second sealing portion being connected between adjacent first sealing portions 22 and cooperating with the first sealing portions 22 to form a slot 24 for the partition 12 to be inserted; and an insertion hole 25 for the chimney 3 to be inserted. Figure 3 , Figure 4 , Figure 6 As shown, at least two first sealing parts 22 of the sealing assembly 2 are inserted into the oil tank 11 in a one-to-one correspondence; at the same time, the partition plate 12 is inserted into the slot 24 formed by the second sealing part and the first sealing part 22; the chimney is inserted into the insertion hole 25; thereby realizing the insertion of the sealing assembly 2 and the oil tank 11, improving the connection strength between the sealing assembly 2 and the oil cup 1, and facilitating the sealing and isolation between the oil tanks 11.

[0062] In the above embodiments, the cartridge further includes a sealing element 4 that seals the sealing assembly 2 and the oil cup 1. The sealing element 4 includes an inner sealing sleeve 42, which is sealed between the outer peripheral surface of the smoke outlet 3 and the inner wall of the insertion hole 25; an outer sealing sleeve 41, which is sealed between the outer peripheral surface of the sealing assembly 2 and the inner wall of the oil cup 1; at least two sealing covers 43, which are correspondingly covered on the first sealing part 22, and the sealing covers 43 are provided with a blocking structure; and a sealing connection part 44, which is connected between adjacent sealing covers 43 and cooperates with the sealing covers 43 to form a U-shaped sealing part. The U-shaped sealing part is sealed between the partition 12 and the inner wall of the slot 24. At least two sealing covers 43 and the sealing connection part 44 are connected between the inner sealing sleeve 42 and the outer sealing sleeve 41.

[0063] like Figures 11-13 As shown, the sealing element 4 consists of an inner sealing sleeve 42, an outer sealing sleeve 41, a sealing connection part 44, and at least two sealing covers 43. The inner sealing sleeve 42 seals the outer peripheral surface of the smoke pipe 3 and the inner wall of the insertion hole 25; the outer sealing sleeve 41 seals the outer peripheral surface of the sealing assembly 2 and the inner wall of the oil cup 1; the sealing connection part 44 and the sealing cover 43 cooperate to form a U-shaped sealing part to seal the partition 12 and the inner wall of the slot 24, thereby achieving a sealed separation between at least two oil tanks 11 and between the oil tank 11 and the smoke outlet channel 31. The sealing cover 43 blocks the flow of e-liquid from the oil tank 11 into the transition oil chamber 21, and the sealing cover 43 is provided with an oil passage hole 43a for the e-liquid in the oil tank 11 to flow into the transition oil chamber 21.

[0064] The seal 4 can be integrally formed into an inner sealing sleeve 42, an outer sealing sleeve 41, a sealing connection part 44, and at least two sealing covers 43. During assembly, the seal 4 can be placed over the end of the sealing assembly 2 facing the oil tank 11, which is convenient for assembly and reduces assembly costs.

[0065] The seal 4 can be made of silicone, and each sealing surface has annular protrusions to improve the sealing effect; it also facilitates manufacturing and reduces costs. The seal 4 can be made of other elastic materials such as elastic rubber, polymer elastomers, etc., as long as elastic sealing is guaranteed. The seal 4 may also include an inner skeleton and an outer elastic layer.

[0066] In some embodiments, the portion of the sealing cover 43 that forms the end of the U-shaped sealing portion protrudes beyond other portions. For example... Figures 11-12 As shown, the depth of the U-shaped sealing part extending into the oil tank 11 is greater than the depth of other parts of the sealing cover 43 extending into the oil tank 11, which can ensure the sealing connection area between the U-shaped sealing part and the partition 12 and improve the sealing isolation effect between the oil tank 11; moreover, the partition 12, the U-shaped sealing part and the slot 24 of the sealing assembly 2 are all straight, which ensures the circumferential fixing strength between the sealing assembly 2 and the oil cup 1.

[0067] In some embodiments, each e-liquid reservoir 11 is equipped with a corresponding atomizing core 5. This allows the atomizing core 5 of the corresponding flavor reservoir 11 to be controlled according to the user's vaping preferences. When vaping one flavor of e-liquid, the atomizing core 5 of the corresponding single e-liquid reservoir 11 is activated. The aerosol generated after atomization by the atomizing core 5 is inhaled into the mouth through the smoke outlet 31. The e-liquid in the transition e-liquid chamber 21 corresponding to that reservoir 11 continuously supplies e-liquid to the atomizing core 5 as it atomizes. When vaping two flavors of e-liquid, the two atomizing cores 5 of the corresponding two e-liquid reservoirs 11 are activated. Both aerosols generated after atomization by the atomizing core 5 are inhaled into the mouth through the same smoke outlet 31, which can improve the flavor blending effect and thus enhance the vaping experience of mixed flavors. The e-liquid in the two transition e-liquid chambers 21 corresponding to the two e-liquid reservoirs 11 continuously supplies e-liquid to the two atomizing cores 5 as they atomize. The same principle applies when vaping more than two flavors of e-liquid; further details are omitted.

[0068] Optional, please refer to Figure 4 All atomizing cores 5 are housed within a single atomization channel 23; the atomization channel 23 and the smoke outlet channel 31 are coaxially aligned, further simplifying the structure and reducing costs. For the two atomizing cores 5 corresponding to the two oil tanks 11, they are positioned opposite each other within the same atomization channel 23 along the arrangement direction of the oil tanks 11. This atomization channel 23 is vertically aligned with the smoke outlet channel 31, facilitating the entry of the aerosol generated after atomization into the smoke outlet channel 31. It is understood that for multiple atomizing cores 5 corresponding to two or more oil tanks 11, they can be arranged circumferentially within the same atomization channel 23.

[0069] Please continue to refer to this. Figure 4 The inner diameter of the atomizing channel 23 is smaller than the inner diameter of the smoke outlet channel 31; thus, the smoke outlet channel 31 can surround the entire atomizing channel 23, further facilitating the entry of the aerosol generated after atomization into the smoke outlet channel 31. In this embodiment, the atomizing channel 23 and the smoke outlet channel 31 can also be set with the same diameter.

[0070] Optional, such as Figure 6 As shown, the atomizing core 5 includes a ceramic block, a heating wire disposed on the ceramic block, wicking cotton covering the heating wire, and electrodes electrically connected to the heating wire. The electrodes are used to connect to the power supply system and energize the heating wire. During operation, the e-liquid in the e-liquid tank 11 first flows into the transition e-liquid chamber 21, and is then absorbed by the wicking cotton into the atomization channel 23, where it is heated and atomized by the heating wire. The ceramic block provides support and has through holes for the aerosol generated by atomization to enter the smoke outlet channel 31.

[0071] In some embodiments, the smoke outlet channel 31 gradually widens from one end near the atomizing channel 23 to the smoke outlet of the cartridge. For example, as shown... Figure 3As shown, the smoke outlet channel 31 is a gradually expanding conical channel, which allows the aerosol generated after atomization to flow and diffuse radially outward, promoting fusion and improving the flavor blending effect, thereby enhancing the smoking experience of mixed flavors. Other embodiments may also include protrusions on the inner wall of the smoke outlet channel 31 to block the smoke and promote the fusion of the two types of smoke, thus improving the smoke blending effect.

[0072] The assembly process of the e-cigarette cartridge provided in this application involves first inverting the oil cup 1 to fill it with oil; then assembling the sealing component 2; next, assembling the sealing element 4 onto the sealing component 2; and finally, inserting the sealing component 2, along with the sealing element 4, into the inverted oil cup 1 that has been filled with oil. The assembly operation is simple and reduces assembly costs.

[0073] This application also provides an electronic atomizing device, including the e-liquid cartridge provided in any of the above embodiments; all e-liquid tanks 11 share a single smoke outlet channel 31, reducing the number of smoke outlet channels 31, thereby simplifying the structure and reducing manufacturing costs. Furthermore, when a user inhales two flavored e-liquids, the two aerosols begin to fuse after entering the same smoke outlet channel 31, extending the fusion path and improving the flavor fusion effect, thus enhancing the vaping experience of mixed flavors. These advantages are derived from the e-liquid cartridge; please refer to the relevant parts in the above embodiments for details, which will not be repeated here.
