Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to an electronic cigarette. Background Technology

[0002] High-capacity e-cigarettes typically include a supply tank, which can store a large amount of e-liquid, allowing for a continuous supply to the reservoir. The atomizing component absorbs the e-liquid from the reservoir and, powered by the electronic control components, atomizes it. The atomized vapor flows out through the mouthpiece connected to the atomizing chamber for the user to inhale. Under normal conditions, the air pressure in the supply tank and reservoir is equal, and roughly equal to the atmospheric pressure of the external environment. However, the reservoir can only store a small amount of e-liquid. As the e-cigarette is used, e-liquid from the supply tank needs to be continuously replenished into the reservoir. The gradual decrease in e-liquid in the supply tank leads to a gradual increase in negative pressure within it, while the gradual increase in e-liquid in the reservoir leads to a gradual increase in air pressure within it. This creates an air pressure imbalance between the supply and reservoir, and due to the surface tension of the e-liquid, the filling of the reservoir from the supply tank becomes slow or even stops. Utility Model Content

[0003] The main purpose of this application is to provide an electronic cigarette that solves the technical problem of slow or even stopped oil filling from the oil supply tank to the oil storage tank.

[0004] To achieve the above objectives, this application proposes an electronic cigarette, the electronic cigarette comprising:

[0005] Oil storage tanks;

[0006] The atomizing component is located inside the oil storage tank;

[0007] A fuel supply tank, located below the fuel storage tank, contains fuel oil; and

[0008] A conduit connects the oil storage chamber and the oil supply chamber at both ends. The conduit guides the e-liquid in the supply chamber into the oil storage chamber, and also guides the gas in the oil storage chamber into the supply chamber. Multiple notches are provided at both ends of the conduit to break the e-liquid tension. These notches are arranged circumferentially along the conduit. The cross-sectional area of ​​the conduit is greater than or equal to 10 mm². 2 and less than or equal to 55mm 2 .

[0009] Optionally, the cross-sectional area of ​​the conductive tube is greater than or equal to 25 mm². 2 and less than or equal to 40mm 2 .

[0010] Optionally, there may be multiple notches, and the multiple notches are arranged circumferentially along the conductive tube.

[0011] Optionally, in the circumferential direction of the conductive tube, the length of the notch is greater than or equal to 0.2 mm and less than or equal to 0.8 mm.

[0012] Optionally, in the axial direction of the conductive tube, the length of the notch is greater than or equal to 2 mm and less than or equal to 5 mm.

[0013] Optionally, in the axial direction of the conductive tube, the length of the notch is greater than or equal to 3 mm and less than or equal to 4 mm.

[0014] Optionally, the top of the guide pipe is higher than the bottom wall of the oil storage tank.

[0015] Optionally, the bottom end of the guide pipe is located at the top of the oil supply tank.

[0016] Optionally, the oil supply tank and the oil storage tank are detachably connected, and a sealing element is provided on the upper part of the oil supply tank.

[0017] Optionally, the electronic cigarette further includes an electronic control chamber and an electronic control component. The electronic control chamber is located between the oil storage chamber and the oil supply chamber, and the conduit passes through the electronic control chamber. The electronic control component is located in the electronic control chamber and is electrically connected to the atomizing component.

[0018] In the electronic cigarette of this application, the cross-sectional area of ​​the conductive tube is 10 mm. 2 ~55mm 2 Therefore, when the e-cigarette is inverted, the e-liquid in the supply tank is subject to gravity and flows into the storage tank through the conduit. Due to its liquid tension, the e-liquid only adheres to the wall of the conduit and flows, creating a cavity in the middle of the conduit. At the same time, the multiple notches at both ends of the conduit break the tension of the e-liquid at the end face, allowing the gas in the storage tank to flow into the supply tank through the cavity inside the conduit. Thus, the air pressure in the storage tank and the supply tank can be kept balanced during the filling process, resulting in a relatively rapid filling of the storage tank with e-liquid.

[0029] This application discloses an electronic cigarette, comprising an e-liquid reservoir, an atomizing component, an e-liquid supply chamber, a conduit, and an airflow tube. The atomizing component is disposed within the e-liquid reservoir. The e-liquid supply chamber is located below the e-liquid reservoir and stores e-liquid within it. The two ends of the conduit are connected to the e-liquid reservoir and the e-liquid supply chamber, respectively. The conduit guides the e-liquid from the supply chamber into the e-liquid reservoir and also guides the airflow from the e-liquid reservoir into the supply chamber. Multiple notches for breaking the e-liquid tension are provided at both ends of the conduit, arranged circumferentially along the conduit. The cross-sectional area of ​​the conduit is 10 mm². 2 ~55mm 2 .

[0030] In the electronic cigarette of this application, the cross-sectional area of ​​the conductive tube is 10 mm. 2 ~55mm 2 Therefore, when the e-liquid in the supply tank flows into the storage tank through the conduit, the e-liquid only adheres to the wall of the conduit and flows, creating a cavity in the middle of the conduit. At the same time, the multiple notches at both ends of the conduit break the tension of the e-liquid, allowing the gas in the storage tank to flow into the supply tank through the cavity inside the conduit. Thus, the air pressure in the storage tank and the supply tank can be kept balanced during the filling process, allowing the supply tank to fill the storage tank relatively quickly.

[0031] The following will mainly describe the specific structure of electronic cigarettes.

[0032] Please see Figure 1 and Figure 2 The electronic cigarette 100 of this application includes an oil storage tank 110, which is used to store e-liquid. The shape of the oil storage tank 110 can be generally cylindrical, and specifically, the cross-section of the oil storage tank 110 can be circular, elliptical, racetrack-shaped, polygonal, or irregular.

[0033] Please see Figure 1 and Figure 2 The electronic cigarette 100 of this application includes an atomizing component 120. The atomizing component 120 is disposed in the oil storage tank 110, and the atomizing component 120 can draw e-liquid from the oil storage tank 110 and atomize the e-liquid into a vapor.

[0034] Please see Figure 1 and Figure 2 The electronic cigarette 100 of this application includes a mouthpiece (not labeled in the figure), which is located above the oil reservoir 110 and is connected to the atomizing component 120. The atomized vapor generated by the atomizing component 120 is discharged to the outside through the mouthpiece.

[0035] Please see Figure 1 and Figure 2The electronic cigarette 100 of this application includes a supply tank 130. The supply tank 130 stores a large amount of e-liquid and is used to supply e-liquid to the storage tank 110. The shape of the supply tank 130 can be generally cylindrical, and its cross-section can be circular, elliptical, racetrack-shaped, polygonal, or irregular. The supply tank 130 can be made of opaque, translucent, or transparent materials, without limitation.

[0036] Please see Figure 1 and Figure 2 The oil supply chamber 130 can be located below the oil storage chamber 110. Thus, by inverting the electronic cigarette 100, oil can be supplied from the oil supply chamber 130 to the oil storage chamber 110, and the oil filling process can be controlled by changing the position of the electronic cigarette.

[0037] Please see Figures 1 to 3 The electronic cigarette 100 of this application includes a conduit 140. The two ends of the conduit 140 are connected to an oil storage chamber 110 and an oil supply chamber 130, respectively. The conduit 140 guides the e-liquid in the oil supply chamber 130 into the oil storage chamber 110, and also guides the gas in the oil storage chamber 110 into the oil supply chamber 130. The conduit 140 and the oil storage chamber 110, and the conduit 140 and the oil supply chamber 130, can be bonded, snap-fitted, or screwed together, respectively.

[0038] Please see Figures 1 to 3 The guide tube 140 has multiple notches 141 at both ends to break the tension of the e-liquid, and these notches 141 are arranged circumferentially along the guide tube 140. The cross-sectional area of ​​the guide tube 140 is greater than or equal to 10 mm². 2 and less than or equal to 55mm 2 Therefore, please refer to Figure 2 When the electronic cigarette 100 is inverted, the e-liquid in the supply tank 130 flows into the storage tank 110 through the conduit 140. Due to its liquid tension, the e-liquid only adheres to the wall of the conduit 140 and flows, forming a cavity in the middle of the conduit 140. At the same time, the notches 141 at both ends of the conduit 140 break the tension of the e-liquid at the end face, and the gas in the storage tank 110 can flow into the supply tank 130 through the cavity inside the conduit 140. Thus, the air pressure in the storage tank 110 and the supply tank 130 can be kept balanced during the filling process, and the filling of e-liquid from the supply tank 130 to the storage tank 110 is relatively rapid.

[0039] Furthermore, the cross-sectional area of ​​the conductive tube 140 can be 25 mm². 2 ~40mm 2 15mm 2 ~35mm 2 30mm 2 ~40mm 2 40mm 2~50mm 2 35mm 2 ~40mm 2 Or 30mm 2 ~55mm 2 Furthermore, the cross-sectional area of ​​the conductive tube 140 can be 10 mm². 2 15mm 2 20mm 2 25mm 2 30mm 2 35mm 2 40mm 2 45mm 2 50mm 2 Or 55mm 2 The cross-section of the conduit 140 can be circular, elliptical, racetrack-shaped, polygonal, or irregular in shape.

[0040] In the circumferential direction of the conduit 140, the length of the notch 141 is greater than or equal to 0.2 mm and less than or equal to 0.8 mm. Therefore, the multiple notches 141 effectively break the e-liquid tension. Further, the aforementioned length can be 0.3–0.7 mm, 0.2–0.6 mm, 0.4–0.6 mm, 0.45–0.55 mm, 0.35–0.8 mm, 0.5–0.6 mm, or 0.3–0.5 mm, etc. Even further, the aforementioned length can be 0.2 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, 0.55 mm, 0.6 mm, 0.65 mm, 0.7 mm, 0.75 mm, or 0.8 mm, etc.

[0041] Along the axial direction of the conduit 140, the length of the notch 141 is greater than or equal to 2 mm and less than or equal to 5 mm. Therefore, multiple notches 141 effectively break the e-liquid tension. Further, the aforementioned length can be 2.5–5 mm, 3–4 mm, 2–4 mm, 3.5–4 mm, 4–5 mm, 3.5–4.5 mm, or 2.5–3 mm, etc. Even further, the aforementioned length can include, but is not limited to, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, or 5 mm, etc.

[0042] The shape of notch 141 can be semicircular, semi-elliptical, triangular, or quadrilateral (e.g., Figures 1 to 3 (As shown) or irregular shapes, as long as they can break the tension of the e-liquid, there are no specific limitations.

[0043] Please see Figure 1 and Figure 2The top of the conduit 140 is higher than the bottom wall of the oil storage tank 110. Therefore, when the e-cigarette 100 is filled with oil (at which time the e-cigarette 100 is upright), the e-liquid flowing into the oil storage tank 110 will not completely flow back to the oil supply tank 130. That is, some e-liquid will remain in the oil storage tank 110. This part of the remaining e-liquid will flow into the atomizing component 120, so that frequent refilling is not required, and the probability of the atomizing component 120 being dry-burned can also be reduced.

[0044] Please see Figure 1 and Figure 2 The top of the conduit 140 is located on the top of the oil storage tank 110. As a result, a relatively large amount of e-liquid remains in the oil storage tank 110, which can further reduce the probability of the atomizing component 120 burning dry.

[0045] Please see Figure 1 and Figure 2 The bottom end of the guide pipe 140 is located at the top of the oil supply tank 130. Please refer to [link / reference needed]. Figure 2 When the e-cigarette 100 is inverted (relative to when the e-cigarette 100 is upright, i.e. when the mouthpiece is facing down), the e-liquid in the supply tank 130 can flow almost all of it into the storage tank 110, without any unwanted residue.

[0046] In one embodiment, the oil supply tank 130 and the oil storage tank 110 are detachably connected, and a sealing element is provided on the upper part of the oil supply tank. The sealing element can seal the oil supply tank 130 to prevent oil leakage. The sealing element can be a sealing membrane or a sealing plug. The separate arrangement of the oil supply tank 130 and the oil storage tank 110 can effectively avoid oil leakage problems during transportation. The bottom end of the guide pipe 140 can be used to puncture the sealing element or push the sealing element away from the sealing position, thereby making the assembly of the oil supply tank 130 and the oil storage tank 110 relatively convenient.

[0047] Please see Figure 1 and Figure 2 The electronic cigarette 100 of this application also includes an electronic control chamber 150. The electronic control chamber 150 is located between the oil storage chamber 110 and the oil supply chamber 130, and the guide tube 140 passes through the electronic control chamber 150. Thus, with the relatively compact structural layout of the electronic cigarette 100, the guide tube 140 has a suitable length of guide path, resulting in better oil guiding and exhaust effects.

[0048] Please see Figure 1 and Figure 2 The electronic cigarette 100 of this application also includes an electronic control component 160, which is disposed within the electronic control chamber 150 and is electrically connected to the atomizing component 120. Thus, the atomizing component 120 can atomize the e-liquid in the oil storage chamber 110 under the control of the electronic control component 160.

[0049] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
