Description

Technical Field

[0001] This utility model relates to the field of electronic cigarettes, and in particular to a structure and electronic cigarette that facilitates the replenishment of e-liquid. Background Technology

[0002] Because e-cigarettes can produce the same smoke as cigarettes and are convenient, they have gradually become popular among smokers. Moreover, the e-liquid in e-cigarettes does not contain harmful substances such as nicotine.

[0003] Currently, the volume of the atomizing chamber in e-cigarettes is regulated in some countries. Therefore, e-cigarettes usually have a tank for storing e-liquid. When the e-liquid in the atomizing chamber is depleted, the tank replenishes it, reducing user anxiety. However, e-liquid can freely flow between the atomizing chamber and the tank. When the tank is not full, there is a risk that the e-liquid in the atomizing chamber may flow back into the tank. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a structure and electronic cigarette that facilitates the replenishment of e-liquid.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A structure for easy refilling of e-liquid includes:

[0007] A cigarette shell, wherein an atomizing chamber, a valve chamber, and an oil tank are disposed within the cigarette shell; the atomizing chamber is connected to the oil tank via the valve chamber; the height of the atomizing chamber within the cigarette shell is higher than the height of the oil tank; and a protruding ring extends from the bottom of the valve chamber of the cigarette shell.

[0008] A gravity ball is disposed in the valve chamber. The gravity ball is held above the convex ring by its own weight, thereby isolating the oil chamber from the atomizing chamber.

[0009] In one embodiment, the smoke shell extends into the valve chamber as a limiting member, which is positioned above the gravity ball.

[0010] In one embodiment, the bottom surface of the convex ring is inclined, and the height of the inclined surface gradually increases from its bottom edge toward the center.

[0011] In one embodiment, the valve chamber includes a movable chamber and a limiting chamber, the movable chamber being in communication with the limiting chamber, the diameter of the movable chamber being larger than the diameter of the limiting chamber, and the convex ring being disposed at the bottom of the limiting chamber.

[0012] In one embodiment, the diameter of the gravity ball is slightly smaller than the diameter of the limiting chamber.

[0013] In one embodiment, the height of the atomizing chamber within the smoke shell is higher than the height of the oil tank.

[0014] In one embodiment, the structure for facilitating e-liquid replenishment further includes an oil bottle with an oil reservoir inside. The bottle has an external thread on the outside of its opening and an internal thread on the inside of the e-liquid shell. The external thread of the oil bottle is screwed into the internal thread of the e-liquid shell.

[0015] An electronic cigarette includes an atomizer, an air tube, and the aforementioned structure for easy refilling of e-liquid. The atomizer is disposed within the atomizing chamber, and a mouthpiece extends from the top of the cigarette shell, the mouthpiece being connected to the air outlet of the atomizer.

[0016] In one embodiment, the electronic cigarette further includes a silicone sleeve, which is hollow inside and is fitted onto the air outlet of the atomizer. The lower end of the mouthpiece is fitted onto the air outlet of the atomizer and the silicone sleeve.

[0017] Compared with the prior art, the present invention has at least the following advantages:

[0018] 1. The structure of this utility model for easy e-liquid replenishment is achieved by incorporating a vapor shell and a gravity ball. The vapor shell contains an atomizing chamber, a valve chamber, and an e-liquid tank. The atomizing chamber is connected to the e-liquid tank via the valve chamber. The height of the atomizing chamber within the vapor shell is higher than the height of the e-liquid tank. A raised ring extends from the bottom of the valve chamber. The gravity ball is positioned within the valve chamber. Due to its own weight, the gravity ball holds the atomizing chamber above the raised ring, preventing e-liquid from flowing into the e-liquid tank during normal use, thus maintaining e-liquid in the atomizing chamber and preventing the atomizer from burning.

[0019] 2. The oil reservoir of this invention is located inside the oil bottle, which is detachably mounted on the vapor chamber. When replacing the oil bottle, a gravity ball presses against the convex ring in the valve chamber. Due to the strong molecular attraction between e-liquid molecules, which has a sticky film effect, the e-liquid seals the gap between the gravity ball and the convex ring, thus isolating the atomizing chamber and the oil reservoir. This prevents the e-liquid in the atomizing chamber from leaking out, allowing for easy replacement of the oil bottle and satisfying users' desire to switch to different flavored e-liquids.

[0024] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0025] This application proposes a structure that facilitates the replenishment of e-liquid; please refer to [link / reference]. Figure 1 The device includes a casing 10 and a gravity ball 30. The casing 10 contains an atomizing chamber 11, a valve chamber 12, and an e-liquid reservoir 21, which hold e-liquid. The atomizing chamber 11 has a smaller volume than the e-liquid reservoir 21, allowing the reservoir to hold more e-liquid. The e-liquid in the atomizing chamber 11 is used to atomize the vaporizer 40. The atomizing chamber 11 is connected to the e-liquid reservoir 21 via the valve chamber 12, allowing e-liquid from the reservoir 21 to flow into the atomizing chamber 11.

[0026] The atomizing chamber 11 is positioned higher than the e-liquid tank 21 within the outer shell 10. A raised ring 15 extends from the bottom of the valve chamber 12 within the outer shell 10. A spherical gravity ball 30 is positioned within the valve chamber 12. When the outer shell 10 is placed upright, the gravity ball 30 is held above the raised ring 15 by its own weight. Due to the strong molecular attraction between e-liquid molecules and the viscous nature of the e-liquid, the e-liquid adheres to the gap between the gravity ball 30 and the raised ring 15, thus isolating the e-liquid tank 21 from the atomizing chamber 11 and preventing communication between them, effectively functioning as a switch. Simultaneously, when the e-liquid in the tank 21 is insufficient, it prevents all the e-liquid in the atomizer 40 from flowing into the tank 21, thus preventing dry burning and damage to the atomizer 40.

[0027] During normal use, the e-liquid shell 10 is placed upright, and the gravity ball 30 is held above the convex ring 15 by its own weight, thus isolating the e-liquid tank 21 from the atomizing chamber 11. When the e-liquid in the atomizing chamber 11 is insufficient, the user only needs to invert the e-liquid shell 10 180 degrees, so that the gravity ball 30 moves away from the convex ring 15 by its own weight, and the e-liquid tank 21 and the atomizing chamber 11 become connected. Since the height of the atomizing chamber 11 inside the e-liquid shell 10 is higher than the height of the e-liquid tank 21 inside the e-liquid shell 10, the e-liquid in the e-liquid tank 21 flows into the atomizing chamber 11 through the valve chamber 12 under the influence of gravity. At the same time, the gas in the atomizing chamber 11 enters the e-liquid tank 21 through the valve chamber 12, maintaining the air pressure balance between the atomizing chamber 11 and the e-liquid tank 21, thereby replenishing the e-liquid in the atomizing chamber 11. After the e-liquid in the atomizing chamber 11 is replenished, the user only needs to point the mouthpiece 42 upwards to achieve a normal inhalation angle. The gravity ball 30 will then reset, blocking the hole in the middle of the convex ring 15 and isolating the e-liquid tank 21 from the atomizing chamber 11. The e-liquid in the atomizing chamber 11 will not flow into the e-liquid tank 21, and the replenished e-liquid can be used by the atomizer 40 for atomization.

[0028] Please refer to it again. Figure 1 The cigarette shell 10 extends into the valve chamber 12 with a limiting member 31. The limiting member 31 is positioned above the gravity ball 30. During use, it prevents the gravity ball 30 from shifting into the atomizing chamber 11 or even getting stuck there. The limiting member 31 prevents the gravity ball 30 from entering the atomizing chamber 11, thus confining it within the valve chamber 12 and improving its reliability. Preferably, the limiting member 31 is elongated.

[0029] Furthermore, the bottom surface of the convex ring 15 is inclined, and the height of the inclined surface gradually increases from its bottom edge towards the center. When the e-liquid in the atomizing chamber 11 is insufficient, the user inverts the shell 10 180 degrees, causing the gravity ball 30 to move away from the convex ring 15 due to its own weight. This connects the e-liquid tank 21 with the atomizing chamber 11, allowing the e-liquid in the tank 21 to flow sequentially along the inclined surface of the convex ring 15 to the valve chamber 12, and finally to the atomizing chamber 11, thus improving the e-liquid replenishment efficiency.

[0030] Furthermore, the structure for easy refilling of e-liquid also includes an oil bottle 20, with an oil reservoir 21 disposed inside the oil bottle 20. Compared to existing technologies, the oil bottle 20 is detachably disposed within the e-liquid housing 10, allowing users to easily replace it with a full bottle or one containing different flavors, thus increasing user choice. Specifically, the inner wall of the e-liquid housing 10 extends with internal threads, while the outer side of the oil bottle 20's opening has external threads, which are compatible with each other. The external threads of the oil bottle 20 are screwed into the internal threads of the e-liquid housing 10, thereby securing the oil bottle 20 within the housing 10. This screw-in fixing method facilitates easy replacement, reduces fixing difficulty and cost, and minimizes the use of fixing materials. When replacing the oil bottle 20, a gravity ball 30 presses against the protruding ring 15 in the valve chamber 12. Due to the strong molecular attraction between e-liquid molecules, which makes them sticky, the e-liquid seals the gap between the gravity ball 30 and the convex ring 15, thus isolating the atomizing chamber 11 and the e-liquid tank 21. This ensures that the e-liquid in the atomizing chamber 11 will not leak out, allowing for the replacement of the e-liquid bottle 20 to meet the user's needs for changing to different flavors of e-liquid.

[0031] Please refer to it again. Figure 1 The valve chamber 12 includes a movable chamber 13 and a limiting chamber 14, with the movable chamber 13 and the limiting chamber 14 connected. The diameter of the movable chamber 13 is larger than the diameter of the limiting chamber 14, and a convex ring 15 is located at the bottom of the limiting chamber 14. When the e-liquid is replenished while the shell 10 is upside down, the gravity ball 30 falls into the movable chamber 13 due to gravity, causing the e-liquid in the oil tank 21 to pass through the limiting chamber 14 and the movable chamber 13 in sequence. This prevents the gravity ball 30 from obstructing the flow rate of the e-liquid in the movable chamber 13, thereby further improving the replenishment efficiency of the e-liquid.

[0032] Furthermore, the diameter of the gravity ball 30 is slightly smaller than the diameter of the limiting chamber 14, so that the gravity ball 30 is precisely pressed on the convex ring 15, thereby improving the accuracy of the gravity ball 30 pressing and thus improving the isolation between the atomizing chamber 11 and the oil chamber 21.

[0033] Please refer to it again. Figure 1 This application also proposes an electronic cigarette, including an atomizer 40, an air duct 41, and a structure for easy refilling of e-liquid. The atomizer 40 is disposed inside an atomizing chamber 11, and a mouthpiece 42 extends from the top of the cigarette shell 10, communicating with the air outlet of the atomizer 40. An air inlet is provided on the cigarette shell 10, communicating with the lower end of the atomizer 40. A power supply is electrically connected to the atomizer 40, and e-liquid in the oil tank 21 enters the atomizing coil of the atomizer 40 from the oil inlet. When the user inhales through the mouthpiece 42, a negative pressure is created inside the cigarette shell 10, forcing outside air to enter the inside of the cigarette shell 10 through the air inlet. Simultaneously, the power supply provides power to the atomizer 40, activating the atomizer 40, and the atomizing coil begins to atomize the e-liquid inside. Air enters the atomizer 40, mixes with the atomized smoke, forming a mixed smoke, which is finally expelled from the mouthpiece 42 due to the negative pressure.

[0034] In addition, the electronic cigarette also includes a silicone sleeve 43, which is hollow inside and fits onto the air outlet of the atomizer 40. The lower end of the mouthpiece 42 fits onto the air outlet of the atomizer 40 and the silicone sleeve 43. Due to its elasticity, the silicone sleeve 43 has a mounting groove at the connection between the atomizer 40 and the mouthpiece 42. The silicone sleeve 43 is interference-fitted into the mounting groove, causing the inner wall of the connection between the atomizer 40 and the mouthpiece 42 to compress the silicone sleeve 43, improving the seal at the connection and preventing air from being drawn into the cigarette shell 10 from the connection, thus reducing the negative pressure effect of the vapor. Furthermore, the silicone sleeve 43 extends along the length of the atomizer 40, increasing its thickness and further improving the seal at the connection between the atomizer 40 and the mouthpiece 42.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
