Abstract
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;

At least one end of the oil guide tube has a first notch for breaking the tension of the e-liquid; and
[0009] The air guide tube is connected to the oil storage tank and the oil supply tank at both ends, respectively. The air guide tube is used to guide the gas in the oil storage tank into the oil supply tank. At least one end of the air guide tube is provided with a second notch for breaking the tension of the e-liquid.
[0010] Optionally, in the axial direction of the oil guide tube, the length of the first notch is greater than or equal to 0.1 mm and less than or equal to 0.8 mm; in the circumferential direction of the oil guide tube, the length of the first notch is greater than or equal to 0.1 mm and less than or equal to 0.8 mm; in the axial direction of the air guide tube, the length of the second notch is greater than or equal to 0.1 mm and less than or equal to 0.8 mm; in the circumferential direction of the air guide tube, the length of the second notch is greater than or equal to 0.1 mm and less than or equal to 0.8 mm.
[0011] Optionally, there are multiple first notches, and the multiple first notches are arranged circumferentially along the oil guide pipe; there are multiple second notches, and the multiple second notches are arranged circumferentially along the gas guide pipe.
[0012] Optionally, the top end of the oil guide tube has the first notch, and the bottom end of the oil guide tube is a pointed tip.

[0014] Optionally, the top end of the oil guide pipe is higher than the bottom wall of the oil storage tank, and the top end of the air guide pipe is flush with the top end of the oil guide cylinder.
[0015] Optionally, the bottom end of the oil guide pipe is located at the top of the oil supply tank, and the bottom end of the air guide pipe is located at the bottom of the oil supply tank.

The electronic control chamber is located between the oil storage chamber and the oil supply chamber, and the air guide tube and the oil guide tube pass through the electronic control chamber. The electronic control component is located in the electronic control chamber and is electrically connected to the atomizing component.
[0019] In the electronic cigarette of this application, when the electronic cigarette is inverted, the e-liquid in the supply chamber is subject to gravity and can be guided by the oil guide tube to flow into the storage chamber. At the same time, the gas in the storage chamber spontaneously flows from high pressure to low pressure and can be guided by the air guide tube to flow into the supply chamber, thereby balancing the air pressure in the storage chamber and the supply chamber. The first and second notches can break the tension of the e-liquid, allowing the e-liquid to flow smoothly into and / or out of the oil guide tube, and the gas to flow smoothly into and / or out of the air guide tube. As a result, the filling of the supply chamber into the storage chamber is relatively rapid. Attached Figure Description

[0030] This application discloses an electronic cigarette, which includes an oil storage tank, an atomizing component, an oil supply tank, an oil guide tube, and an air guide tube. The atomizing component is disposed in the oil storage tank. The oil supply tank is disposed below the oil storage tank and stores e-liquid. The two ends of the oil guide tube are respectively connected to the oil storage tank and the oil supply tank, and the oil guide tube is used to guide the e-liquid in the oil supply tank into the oil storage tank. At least one end of the oil guide tube has a first notch for breaking the tension of the e-liquid. The two ends of the air guide tube are respectively connected to the oil storage tank and the oil supply tank, and the air guide tube is used to guide the gas in the oil storage tank into the oil supply tank. At least one end of the air guide tube has a second notch for breaking the tension of the e-liquid.
[0031] In the electronic cigarette of this application, when the e-liquid in the supply chamber is guided by the oil guide tube into the storage chamber, the gas in the storage chamber is guided by the air guide tube into the supply chamber, thereby balancing the air pressure between the supply chamber and the storage chamber; the first and second notches can break the tension of the e-liquid, so that the e-liquid can flow smoothly into and / or out of the oil guide tube, and the gas can flow smoothly into and / or out of the air guide tube; thus, the supply chamber can fill the storage chamber with e-liquid relatively quickly.
[0032] The following will mainly describe the specific structure of electronic cigarettes.
[0033] 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.
[0034] 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.
[0035] 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.
[0036] Please see Figure 1 and Figure 2 The 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.
[0037] 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.
[0038] Please see Figures 1 to 3 The electronic cigarette 100 of this application includes an oil guide tube 140. The two ends of the oil guide tube 140 are respectively connected to an oil storage chamber 110 and an oil supply chamber 130. The oil guide tube 140 is used to guide the e-liquid in the oil supply chamber 130 into the oil storage chamber 110. Thus, the e-liquid in the oil supply chamber 130 can be guided by the oil guide tube 140, thereby flowing more effectively into the oil storage chamber 110.
[0039] Please see Figures 1 to 3 At least one end of the wicking tube 140 has a first notch 141, which is used to break the tension of the e-liquid. This allows the e-liquid to flow smoothly into and / or out of the wicking tube 140, reducing the difficulty of wicking and speeding up the filling process. The shape of the first notch 141 can be semi-circular, semi-elliptical, triangular, quadrilateral, or irregular, as long as it can break the tension of the e-liquid; no specific limitation is imposed.
[0040] Please see Figures 1 to 3 Specifically, the top of the oil guide tube 140 has a first notch 141. Thus, when the electronic cigarette 100 is upright, some e-liquid can quickly flow back into the oil guide tube 140 and flow downward along the oil guide tube 140 into the oil supply chamber 130. This can prevent the atomizing component 120 from being soaked in e-liquid for too long, thereby reducing the risk of e-liquid leakage.
[0041] Along the axial direction of the oil guide tube 140, the length of the first notch 141 is greater than or equal to 0.1 mm and less than or equal to 0.8 mm. Therefore, the first notch 141 effectively breaks the tension of the e-liquid. 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.
[0042] In the circumferential direction of the oil guide tube 140, the length of the first notch 141 is greater than or equal to 0.1 mm and less than or equal to 0.8 mm. Therefore, the first notch 141 effectively breaks the tension of the e-liquid. 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.
[0043] Please see Figures 1 to 3 There are multiple first notches 141, which are arranged circumferentially along the oil guide tube 140. Therefore, the first notches 141 are effective in breaking the tension of the e-liquid.
[0044] Please see Figures 1 to 3 The bottom end of the oil guide tube 140 is a pointed tip 142. The pointed tip 142 of the oil guide tube 140 can break the tension of the e-liquid to a certain extent, while guiding the e-liquid to flow into the oil guide tube 140.
[0045] Please see Figure 1 and Figure 2 The top of the oil guide tube 140 is higher than the bottom wall of the oil storage chamber 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 chamber 110 will not completely flow back to the oil supply chamber 130. That is, some e-liquid will remain in the oil storage chamber 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.
[0046] Please see Figure 1 and Figure 2The bottom end of the oil 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., the mouthpiece is facing down), the e-liquid in the oil supply chamber 130 can flow almost all of it into the oil storage chamber 110, without any unwanted residue.
[0047] Please see Figures 1 to 3 The electronic cigarette 100 of this application includes an air guide tube 150. The two ends of the air guide tube 150 are connected to an oil storage chamber 110 and an oil supply chamber 130, respectively. The air guide tube 150 guides the gas in the oil storage chamber 110 into the oil supply chamber 130. Thus, when the electronic cigarette is inverted, and the e-liquid in the oil supply chamber 130 is guided by the air guide tube 140 into the oil storage chamber 110, the gas in the oil storage chamber 110 is also guided by the air guide tube 150 into the oil supply chamber 130. This balances the air pressure between the oil storage chamber 110 and the oil supply chamber 130, allowing the e-liquid in the oil supply chamber 130 to flow into the oil storage chamber 110 at a relatively fast speed. The cross-section of the air guide tube 150 can also be circular, elliptical, racetrack-shaped, polygonal, or irregularly shaped.
[0048] Please see Figures 1 to 3 At least one end of the air duct 150 has a second notch 151, which is also used to break the e-liquid tension. This reduces the obstruction of e-liquid to gas flow, allowing gas to flow smoothly into and / or out of the air duct 150, resulting in better e-liquid filling. The shape of the second notch 151 can also be semi-circular, semi-elliptical, triangular, quadrilateral, or irregular.
[0049] Please see Figures 1 to 3 Specifically, a second notch 151 is provided at both ends of the vent pipe 150. As a result, gas can flow in and out of the vent pipe 150 quickly, thus achieving a better oil injection effect.
[0050] Along the axial direction of the air duct 150, the length of the second notch 151 is greater than or equal to 0.1 mm and less than or equal to 0.8 mm. Therefore, the second notch 151 effectively breaks 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.
[0051] In the circumferential direction of the air duct 150, the length of the second notch 151 is greater than or equal to 0.1 mm and less than or equal to 0.8 mm. Therefore, the second notch 151 effectively breaks 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.
[0052] Please see Figures 1 to 3 There are multiple second notches 151, which are arranged circumferentially along the air duct 150. Therefore, the second notches 151 are effective in breaking the tension of the e-liquid.
[0053] Please see Figure 1 and Figure 2 The top of the air duct 150 is flush with the top of the oil duct 140, meaning the top of the air duct 150 is also higher than the bottom wall of the oil reservoir 110. Therefore, after the e-cigarette 100 is filled with oil (at which point the e-cigarette 100 is upright), a relatively large amount of e-liquid remains in the oil reservoir 110, which can further reduce the probability of the atomizing component 120 burning dry.
[0054] Please see Figure 1 and Figure 2 The bottom end of the vent pipe 150 is located at the bottom of the fuel supply tank 130. Please refer to [link / reference needed]. Figure 2 When the electronic cigarette 100 is inverted, the air duct 150 is located at one end of the oil supply chamber 130 (at this time, the top) and is connected to the cavity above the e-liquid in the oil supply chamber 130. Thus, the gas will not be sealed by the e-liquid and can be quickly discharged from the air duct 150 to the oil supply chamber 130.
[0055] Please see Figures 1 to 3 The oil guide pipe 140 connects to the air guide pipe 150. One side of the oil guide pipe 140 can be connected to one side of the air guide pipe 150 (e.g., Figures 1 to 3 (as shown); or, the diameter of the oil guide tube 140 is larger than the diameter of the air guide tube 150, and the oil guide tube 140 is sleeved on the outside of the air guide tube 150. The oil guide tube 140 and the air guide tube 150 can be integrally formed (e.g., Figures 1 to 3 As shown), it can also be detachably connected (by snap-fit, adhesive or screw connection, etc.).
[0056] 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 130. 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 during transportation. The bottom end of the vent pipe 150 can be used to puncture the oil supply tank 130 or push the sealing element away from the sealing position, thus, the assembly of the oil supply tank 130 and the oil storage tank 110 is relatively convenient. Specifically, in one embodiment, the vent pipe 150 and the oil pipe 140 are connected to the oil storage tank 110. When the oil supply tank 130 is assembled with the oil storage tank 110, one end of the vent pipe 150 extending out of the oil storage tank 110 punctures the seal. As the oil supply tank 130 and the oil storage tank 110 continue to approach each other, one end of the oil pipe 140 extending out of the oil storage tank 110 is also inserted into the oil supply tank 130. The oil supply tank 130 and the oil storage tank 110 continue to approach each other until the assembly is completed. The oil supply tank 130 and the oil storage tank 110 can be connected by snap-fit, adhesive, screw, or magnetic attraction.
[0057] Please see Figure 1 and Figure 2 The electronic cigarette 100 of this application also includes an electronic control chamber 160. The electronic control chamber 160 is located between the oil storage chamber 110 and the oil supply chamber 130, and the air guide tube 150 and the oil guide tube 140 pass through the electronic control chamber 160. Thus, with a relatively compact structural layout, the oil guide tube 140 and the air guide tube 150 have a suitable length of conduction path, resulting in better oil and air conduction effects.
[0058] Please see Figure 1 and Figure 2 The electronic cigarette 100 of this application also includes an electronic control component 170, which is disposed within the electronic control chamber 160 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 170.
[0059] 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.
