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 refill tank, which can store a large amount of e-liquid, allowing for a continuous supply of e-liquid to the main tank. The atomizing component absorbs the e-liquid from the tank and, powered by the electrical component, atomizes it. The atomized vapor then flows out through the mouthpiece connected to the atomizing tank for the user to inhale.

[0003] However, the existing design of large-capacity e-cigarettes is not ideal, requiring users to manually fill the e-liquid tank from the supply tank into the storage tank. Manual filling makes it difficult to precisely control the amount of e-liquid added, leading to inconsistent e-liquid levels in the storage tank. Too much e-liquid in the tank can cause leakage from the atomizer and insufficient atomization, while too little e-liquid can cause the atomizer to burn out. Utility Model Content

[0004] The main purpose of this application is to provide an electronic cigarette that solves the technical problem of unstable e-liquid content in the e-liquid storage tank.

[0005] To achieve the above objectives, this application proposes an electronic cigarette, the electronic cigarette comprising:

[0006] The shell contains an oil supply tank and an oil storage tank.

[0007] The oil conduit has two ends connected to the oil supply tank and the oil storage tank, respectively; and

[0008] A float plug is provided inside the oil passage cylinder;

[0009] The float is movable within the oil-passing cylinder. The float has a first position and a second position. In the first position, the e-liquid in the oil-passing cylinder has a first liquid level, and the float closes the connection between the oil-passing cylinder and the oil supply chamber. In the second position, the e-liquid in the oil-passing cylinder has a second liquid level, and the float opens the connection between the oil-passing cylinder and the oil supply chamber. The first liquid level is higher than the second liquid level.

[0010] Optionally, the float is slidably connected to the oil passage cylinder.

[0011] Optionally, the oil supply tank includes a connecting sidewall that connects to the oil passage cylinder, the connecting sidewall having an oil injection hole that communicates with the oil passage cylinder, the diameter of the oil injection hole being smaller than the inner diameter of the oil passage cylinder; in the first position, the float plug blocks the oil injection hole, and in the second position, the float plug opens the oil injection hole.

[0012] Optionally, the electronic cigarette further includes a connecting tube, which is sleeved inside the oil-filling tube. One end of the connecting tube is connected to the connecting sidewall, and the connecting tube communicates with the oil filling hole. The projection of the connecting tube on the connecting sidewall surrounds the oil filling hole or coincides with the oil filling hole. In the first position, the float plug blocks the connecting tube, and in the second position, the float plug leaves the connecting tube.

[0013] Optionally, the inner diameter of the end of the connecting cylinder connected to the connecting sidewall is greater than or equal to the diameter of the oil injection hole and less than the inner diameter of the end of the connecting cylinder away from the connecting sidewall, and the longitudinal cross-section of the connecting cylinder is semi-racetrack-shaped, semi-olive-shaped, semi-circular, or semi-elliptical.

[0014] Optionally, the longitudinal section of the float is in the shape of an inverted T or an L.

[0015] Optionally, one end of the oil passage cylinder is inserted into the oil storage tank and an oil passage hole is formed on its periphery. The oil passage hole is strip-shaped and its length direction is parallel to the axial direction of the oil passage cylinder.

[0016] Optionally, the oil storage compartment includes a first sub-compartment and a second sub-compartment that are interconnected. The first sub-compartment is connected to the oil outlet. The electronic cigarette also includes an atomizing component, an oil-collecting cotton, and a partition. The atomizing component is disposed in the second sub-compartment and has an oil inlet. The oil-collecting cotton is disposed in the second sub-compartment and is sleeved over the atomizing component. The partition is located between the first sub-compartment and the second sub-compartment and has an oil passage connecting the first sub-compartment and the second sub-compartment.

[0017] Optionally, the top of the oil passage hole is lower than the bottom of the oil inlet hole.

[0018] Optionally, the bottom surface of the float is parallel to the horizontal plane.

[0019] Optionally, the float includes a sealing cap and a bottom cover, the sealing cap being hollow inside, and the bottom cover being attached to the bottom end of the sealing cap.

[0020] In this electronic cigarette application, the e-liquid cartridge connects the e-liquid supply chamber and the e-liquid storage chamber, thus the e-liquid content within the cartridge varies. A float is located within the cartridge and floats on the surface of the e-liquid. Therefore, when the e-liquid content in the cartridge changes, the position of the float changes with the liquid level. The movement of the float can close or open the connection between the cartridge and the supply chamber. This allows for automatic replenishment of e-liquid in the cartridge, maintaining a dynamic balance in the storage chamber. This reduces the risk of leakage and insufficient atomization due to excessive e-liquid content, or dry burning of the atomizing component due to insufficient e-liquid content.

[0030] This application discloses an electronic cigarette, which includes a shell, an e-liquid cartridge, and a float plug. The shell has an e-liquid supply chamber and an e-liquid storage chamber inside. The two ends of the e-liquid cartridge are respectively connected to the e-liquid supply chamber and the e-liquid storage chamber. The float plug is disposed inside the e-liquid cartridge. The float plug is movable inside the e-liquid cartridge and has a first position and a second position. In the first position, the e-liquid in the e-liquid cartridge has a first liquid level, and the float plug closes the connection between the e-liquid cartridge and the e-liquid supply chamber. In the second position, the e-liquid in the e-liquid cartridge has a second liquid level, and the float plug opens the connection between the e-liquid cartridge and the e-liquid supply chamber. The first liquid level is higher than the second liquid level.

[0031] In this electronic cigarette application, the e-liquid cartridge connects the supply tank and the storage tank, thus the e-liquid content within the cartridge changes. A float plug is located inside the cartridge and floats on the surface of the e-liquid. Therefore, when the e-liquid content in the cartridge changes, the position of the float plug changes with the liquid level. The movement of the float plug can close or open the connection between the cartridge and the supply tank. When the e-liquid in the cartridge is at the first liquid level, the float plug, floating above the e-liquid, is in the first position, closing the connection between the cartridge and the supply tank. As the e-liquid content in the storage tank decreases due to atomization, the e-liquid in the cartridge flows into the storage tank, and the e-liquid level in the cartridge drops to the second liquid level. The float plug moves down to the second position with the decreasing liquid level, opening the connection between the cartridge and the supply tank, allowing e-liquid from the supply tank to flow into the cartridge. As the e-liquid content in the cartridge increases, the e-liquid returns to the first liquid level, and the float plug moves back up to the first position, closing the connection between the cartridge and the supply tank. As a result, the e-liquid in the oil can be automatically replenished, so that the e-liquid content in the oil tank can be dynamically balanced. This reduces the occurrence of oil leakage and insufficient atomization caused by excessive e-liquid content, or dry burning of the atomizing component caused by insufficient e-liquid content.

[0032] The following will mainly describe the specific structure of electronic cigarettes.

[0033] Please see Figure 1 and Figure 2The electronic cigarette 100 of this application includes a housing 110. The housing 110 is cylindrical, and its cross-section can be circular, elliptical, racetrack-shaped, polygonal, or irregular. The housing 110 can be made of a non-transparent material, or it can be made of a transparent or translucent material.

[0034] Please see Figure 1 and Figure 2 The shell 110 has an oil supply chamber 111 and an oil storage chamber 113 inside. The oil supply chamber 111 can store a large amount of e-liquid and inject the e-liquid into the oil storage chamber 113.

[0035] Please see Figure 1 and Figure 2 The electronic cigarette 100 of this application also includes an atomizing component 160. The atomizing component 160 is disposed in the oil reservoir 113 and has an oil inlet 161. The e-liquid in the oil reservoir 113 can flow into the atomizing component 160 through the oil inlet 161, and the atomizing component 160 then atomizes the e-liquid into an aerosol for the user to inhale.

[0036] Please see Figure 1 and Figure 2 The electronic cigarette 100 of this application includes an e-liquid feed tube 140, with its two ends connected to an e-liquid supply chamber 111 and an e-liquid storage chamber 113, respectively. The e-liquid supply chamber 111, the feed tube 140, and the storage chamber 113 can be arranged in various ways; the e-liquid supply chamber 111 can be located above or to one side of the feed tube 140, and the feed tube 140 can be located above or to one side of the storage chamber 113. E-liquid flows from the supply chamber 111 through the feed tube 140 into the storage chamber 113 under the influence of gravity.

[0037] Please see Figure 1 and Figure 2 The electronic cigarette 100 of this application includes a float 120, which is disposed inside the e-liquid reservoir 140. The float 120 is able to float on the surface of the e-liquid.

[0038] The float 120 is movable within the oil passage 140, and the float 120 has a first position and a second position. (See also...) Figure 1 In the first position, the e-liquid in the oil conduit 140 has a first liquid level, and the float plug 120 seals the connection between the oil conduit 140 and the oil supply chamber 111. (See also...) Figure 2 In the second position, the e-liquid in the oil conduit 140 has a second liquid level. The float plug 120 opens the connection between the oil conduit 140 and the oil supply chamber 111, and the first liquid level is higher than the second liquid level. As a result, the e-liquid in the oil conduit 140 can be automatically replenished, so that the e-liquid content in the oil storage chamber 113 can be dynamically balanced. This reduces the occurrence of oil leakage and insufficient atomization of the atomizing component 160 due to excessive e-liquid content, or dry burning of the atomizing component 160 due to insufficient e-liquid content.

[0039] Please see Figure 1 and Figure 2 The float 120 is slidably connected to the oil passage 140. Thus, the oil passage 140 can guide and limit the movement of the float 120, resulting in a better movement effect of the float 120.

[0040] Please see Figure 1 and Figure 2 The axial direction of the oil passage 140 is parallel to the vertical direction, thus the float 120 is better guided and limited by the oil passage 140.

[0041] Please see Figure 1 and Figure 2 The oil supply tank 111 includes a connecting side wall 130, which is connected to an oil cylinder 140. The connecting side wall 130 has an oil injection hole 131 that connects to the oil cylinder 140, so that the oil supply tank 111 and the oil cylinder 140 can be connected.

[0042] Please see Figure 1 and Figure 2 The diameter of the oil filling hole 131 is smaller than the inner diameter of the oil passage 140. In the first position, the float plug 120 blocks the oil filling hole 131, and in the second position, the float plug 120 opens the oil filling hole 131. Therefore, the float plug 120 will not detach from the oil passage 140 via the oil filling hole 131, thus enabling the float plug 120 to either block or open the oil filling hole 131.

[0043] Please see Figure 1 and Figure 2 When the diameter of the oil filling hole 131 is smaller than the inner diameter of the oil passage sleeve 140, the longitudinal section shape of the float plug 120 can be inverted T-shape or L-shape. Therefore, the shape of the float plug 120 is well-suited to the shapes of the oil passage sleeve 140 and the oil filling hole 131. Specifically, when the float plug 120 blocks the oil filling hole 131, the top of the float plug 120 can be inserted into the oil filling hole 131, thus the float plug 120 has a good sealing effect on the connection between the oil filling hole 131 and the oil passage sleeve 140.

[0044] Please see Figure 1 and Figure 2 The electronic cigarette 100 of this application also includes a connecting tube 150. The connecting tube 150 is sleeved inside the oil passage tube 140, one end of the connecting tube 150 is connected to the connecting side wall 130, the connecting tube 150 is connected to the oil filling hole 131, and the projection of the connecting tube 150 on the connecting side wall 130 surrounds the oil filling hole 131 or coincides with the oil filling hole 131.

[0045] Please see Figure 1 In the first position, the float 120 seals the connecting cylinder 150. (See also...) Figure 2In the second position, the float 120 moves away from the connecting cylinder 150. Thus, by blocking or moving away from the connecting cylinder 150, the float 120 can achieve the effect of closing or opening the connection between the oil pipe 140 and the oil supply chamber 111. The connecting cylinder 150 enhances the stability of the connection between the float 120 and the oil supply chamber 111, reducing the adverse effects of vortices generated by e-liquid flow on the float 120; furthermore, by moving a certain distance, the float 120 opens the oil supply chamber 111 to inject e-liquid, slowing down the oil flow process and resulting in a better dynamic balance of e-liquid content in the oil storage chamber 113.

[0046] Please see Figure 1 and Figure 2 In one embodiment, the inner diameter of the end of the connecting cylinder 150 connected to the connecting sidewall 130 is greater than or equal to the diameter of the oil injection hole 131, and less than the inner diameter of the end of the connecting cylinder 150 away from the connecting sidewall 130. The longitudinal cross-section of the connecting cylinder 150 is semi-racetrack-shaped, semi-olive-shaped, semi-circular, or semi-elliptical. Therefore, the contact area between the float plug 120 and the connecting cylinder 150 is relatively large, resulting in a better connection and facilitating the insertion of the float plug 120 into the connecting cylinder 150.

[0047] Please see Figure 1 and Figure 2 In the above embodiments, the longitudinal cross-section of the float plug 120 can also be inverted T-shape or L-shape. Therefore, the shape of the float plug 120 is well-suited to the shapes of the oil passage cylinder 140 and the connecting cylinder 150. Specifically, when the float plug 120 blocks the connecting cylinder 150, the top end of the float plug 120 can be inserted into the connecting cylinder 150, thus the float plug 120 has a good sealing effect on the connection between the connecting cylinder 150 and the oil passage cylinder 140.

[0048] Please see Figure 1 and Figure 2 One end of the e-liquid feed cylinder 140 is inserted into the e-liquid storage tank 113, and an e-liquid flow hole 141 communicating with the e-liquid storage tank 113 is opened on its periphery. The e-liquid flow hole 141 is strip-shaped, and its length direction is parallel to the axial direction of the e-liquid feed cylinder 140. As a result, the e-liquid in the e-liquid feed cylinder 140 can flow into the e-liquid storage tank 113 relatively quickly, so that the e-liquid in the e-liquid storage tank 113 can be replenished in a timely manner, and the dynamic balance of e-liquid content in the e-liquid storage tank 113 is better.

[0049] Please see Figure 1 and Figure 2 In one embodiment, the electronic cigarette 100 of this application further includes an oil-retaining cotton 180. The oil-retaining cotton 180 is disposed inside the oil storage chamber 113 and is sleeved on the outside of the atomizing component 160. The oil-retaining cotton 180 can absorb the e-liquid in the oil storage chamber 113 and transfer the e-liquid to the atomizing component 160 through the oil inlet 161.

[0050] Please see Figure 1 and Figure 2 In the above embodiment, the oil storage chamber 113 includes a first sub-chamber 114 and a second sub-chamber 115 that are interconnected. The first sub-chamber 114 is connected to the oil cylinder 140, and the atomizing component 160 and the oil storage cotton 180 are disposed in the second sub-chamber 115. Thus, the liquid level of the e-liquid in the first sub-chamber 114 is equal to the liquid level of the e-liquid in the oil cylinder 140 (the e-liquid in the second sub-chamber 115 is absorbed by the oil storage cotton 180). The e-liquid in the first sub-chamber 114 and the e-liquid in the oil cylinder 140 can generate sufficient buoyancy for the float 120, so that the float 120 floats on the surface of the e-liquid, realizing its function of closing or opening the connection between the oil cylinder 140 and the oil supply chamber 111.

[0051] Please see Figure 1 and Figure 2 The electronic cigarette 100 of this application also includes a partition 170. The partition 170 is located between the first sub-compartment 114 and the second sub-compartment 115, and the partition has an oil passage hole 171 that connects the first sub-compartment 114 and the second sub-compartment 115. The oil passage hole 171 can regulate the speed at which the e-liquid in the first sub-compartment 114 flows into the second sub-compartment 115.

[0052] Please see Figure 1 and Figure 2 The top of the oil passage 171 is lower than the bottom of the oil inlet 161. As a result, the e-liquid is transferred against gravity within the oil storage cotton 180, which can prevent the oil film on the atomizing core of the atomizing component 160 from becoming too thick, thus achieving a better atomization effect and reducing the probability of oil leakage from the atomizing component 160.

[0053] Please see Figure 1 and Figure 2 The bottom surface of the float plug 120 is parallel to the horizontal plane. As a result, the float plug 120 has a better floating effect on the e-liquid, thus enabling it to better perform its function of sealing or opening the connection between the e-liquid cylinder 140 and the e-liquid supply chamber 111.

[0054] Please see Figure 1 and Figure 2 The float plug 120 includes a sealing cap 121 and a bottom cover 122. The sealing cap 121 is hollow inside, and the bottom cover 122 is attached to the bottom end of the sealing cap 121. As a result, the float plug 120 has a relatively large bottom area, which allows it to float on the surface of the e-liquid more ideally. Thus, the float plug 120 can effectively perform its function of sealing or opening the connection between the e-liquid cartridge 140 and the e-liquid supply chamber 111.

[0055] 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.
