Description

Technical Field

[0001] The present application relates to the field of electronic cigarettes, and in particular to an electronic cigarette with automatic oil refilling. Background Art

[0002] In the e-cigarette industry, the basic working principle of e-cigarettes is to use batteries to provide energy to the heating element, which then heats the e-liquid to atomize it. Users inhale the atomized e-liquid vapor through the suction end to simulate the smoking experience. In the prior art, the delivery and atomization process of the e-liquid is the core of the e-cigarette experience. The e-liquid is usually stored in the oil tank of the e-cigarette and is transferred to the atomizer core through various mechanisms. The atomizer core is heated to atomize the e-liquid. In this process, the flow control of the e-liquid is crucial to ensure the consistency of the user's smoking experience.

[0003] In the prior art, it is often difficult to accurately control the amount of oil produced by the direct combination of e-liquid and atomizer core. There are variables in the fluidity of the e-liquid and the oil absorption capacity of the atomizer core, including but not limited to the viscosity of the e-liquid, the physical structure of the atomizer core, the temperature of the use environment, etc. Therefore, users may encounter inconsistent taste problems every time they smoke, such as too much or too little smoke, which affects the smoking experience.

[0004] In order to solve the above-mentioned oil output control problem, some products in the industry have adopted complex oil control mechanisms, such as solenoid valve control systems. These systems can more accurately control the amount of oil flowing to the atomizer core, thereby improving the consistency of taste when smoking. However, this solution brings new problems: increasing the structural complexity and production cost of electronic cigarettes. The introduction of precision components such as solenoid valves not only increases the difficulty of manufacturing, but also increases the overall cost of electronic cigarettes, which may affect the competitiveness of products in a highly competitive market.

[0005] While pursuing a better user experience, the e-cigarette industry is also facing the pressure of cost control. Although complex oil control mechanisms can improve the experience, the high cost and production difficulty limit the popularization and promotion of these technologies. For consumers, excessive costs will affect their willingness to buy; for manufacturers, high costs may compress profit margins and affect their market competitiveness.

[0006] In view of the above problems, the e-cigarette industry urgently needs a new e-cigarette structure design. Utility Model Content

[0007] The purpose of the present application is to overcome at least one of the shortcomings of the prior art and to provide an electronic cigarette with automatic oil replenishment, which has a simple structure, is easy to produce and has low cost, and can achieve precise oil control.

[0008] To achieve the above-mentioned purpose, the present application discloses an automatic oil-replenishing electronic cigarette, comprising a sealed oil tank, a smoke pipe passing through the oil tank, and an atomizer core located in the smoke pipe, wherein a smoke duct is provided in the hollow smoke pipe, the tube wall of the smoke pipe is at least partially hollow, and an oil storage cotton layer is sandwiched in the hollow; the smoke pipe is provided with at least one air inlet hole connected to the oil tank at the upper part, the air inlet hole is higher than the liquid level in the oil tank and is covered by the oil storage cotton layer, the smoke pipe is provided with an oil inlet hole connected to the oil tank at a bottom position close to the oil tank, the oil inlet hole is covered by the oil storage cotton layer, and when the oil storage cotton layer is full of oil, the air inlet hole is sealed; the atomizer core fixed in the smoke pipe is in direct contact and cooperation with the oil storage cotton layer, and oil is delivered to the atomizer core via the oil storage cotton layer.

[0009] Furthermore, the automatic oil-refilling electronic cigarette also includes a mouthpiece connected to the flue in the smoke pipe.

[0010] Furthermore, the automatic oil-refilling electronic cigarette also includes a control mainboard for supplying power to the atomizer core and controlling the operation of the atomizer core. The control mainboard is connected to a battery and is powered by the battery.

[0011] In some embodiments, the oil tank is composed of a sealed shell, the smoke pipe passes through the sealed shell and is connected to the sealed shell as a whole, and the smoke pipe is provided with a matching notch at a matching position of the atomizer core.

[0012] In some embodiments, the oil tank is composed of a sealed shell with a hole reserved on the shell to match the smoke pipe; the smoke pipe is inserted into the shell through the hole, and sealing silicone is used at the matching position to achieve connection sealing.

[0013] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0014] 1. Simplified structure and cost reduction: By integrating the oil storage cotton layer into the smoke tube, this technology simplifies the path of oil delivery to the atomizer core and reduces the need for additional components to control oil delivery (such as solenoid valves, etc.), thereby simplifying the structure of the entire electronic cigarette and reducing production and maintenance costs.

[0015] 2. Automatically control the oil output to improve the consistency of experience: The design of the smoke pipe realizes the automatic replenishment and precise control of the oil. The oil storage cotton layer can automatically close the air inlet after being full of oil, so that negative pressure is formed in the oil tank, preventing excessive oil from flowing into the atomization core, ensuring the consistency of the quantity and quality of smoke every time you smoke, and significantly improving the user's smoking experience.

[0016] 3. Easy to produce and maintain: The design of this electronic cigarette is convenient for mass production. The structural design of the oil storage cotton layer and the smoke pipe makes the assembly process easier, and it is also convenient for users to maintain and replace the atomizer core or oil storage cotton layer during long-term use.

[0017] In summary, the present invention reduces the waste of smoke oil by precisely controlling the delivery of smoke oil. The smoke oil is evenly delivered to the atomizer core through the oil storage cotton layer, avoiding insufficient atomization or smoke oil overflow caused by uneven smoke oil delivery, and improving the use efficiency of the smoke oil.

[0026] Figure 1An exemplary structure for achieving the purpose of the present application is shown, specifically an electronic cigarette with automatic oil replenishment, which aims to solve the problem of oil replenishment and control in the electronic cigarette through a unique structural design to enhance the user's smoking experience. The electronic cigarette is mainly composed of the following parts: a sealed oil tank 1, a smoke pipe 3 that passes through the oil tank 1 and forms a flue 2 using a hollow structure, an atomizer core 4 located inside the smoke pipe 3, a cigarette holder 5 connected to the flue 2, and a control mainboard (not shown in the figure) for supplying power to the atomizer core 4 and controlling its operation, and a battery (not shown in the figure) for supplying power to the control mainboard. In the above structure, the oil tank 1 is sealed and used to store the oil, and the oil tank 1 and the smoke pipe 3 are used to achieve stable oil supply to the atomizer core 4, and after reaching the oil supply threshold, the oil output of the oil tank 1 is closed.

[0027] As a further description of this embodiment, in this embodiment, the smoke pipe 3 has a flue 2 for gas to pass through. The pipe wall of the smoke pipe 3 is at least partially hollow, and the hollow part is sandwiched with an oil storage cotton layer 6. The oil storage cotton layer 6 serves as an intermediate oil storage body and is used to control the oil supply opening and closing of the oil bin 1. In order to achieve the above-mentioned purpose of oil supply opening and closing and intermediate oil storage, the smoke pipe 3 has an air inlet 7 and an oil inlet 8 outside the structure. Specifically, at least one air inlet 7 connected to the oil bin 1 is designed at the upper part of the smoke pipe 3. The air inlet is located above the liquid level of the smoke oil 9 in the oil bin 1 and is covered by the oil storage cotton layer 6. When the oil storage cotton layer 6 is full of oil, the oil storage cotton layer 6 mixed with the smoke oil 9 expands to seal the air inlet 7, thereby preventing air from entering, so that a slightly negative pressure state is formed inside the oil bin 1, maintaining the sealing of the oil bin 1 and controlling the flow of the smoke oil 9. At a position of the smoke pipe 3 close to the bottom of the oil tank 1, an oil inlet hole 8 connected to the oil tank 1 is designed, and the hole is also covered by the oil storage cotton layer 6 to ensure that the smoke oil 9 can be absorbed by the oil storage cotton layer 6 and transported to the atomization core 4 as needed.

[0028] As a more detailed description of this embodiment, more specifically, the oil tank 1 is composed of a sealed shell, and a hole is reserved on the shell to match the smoke pipe 3. The smoke pipe 3 is inserted into the shell through the hole, and the sealing silicone 10 is used at the matching position to achieve the connection and sealing with the shell. This design not only ensures the sealed storage of the smoke oil, but also facilitates the installation and maintenance of the smoke pipe 3.

[0029] In addition, in order to ensure that the atomizer core 4 can effectively contact the oil storage cotton layer 6, the smoke tube 3 is provided with a matching notch at the matching position of the atomizer core 4. This notch ensures that the atomizer core 4 can fully contact the oil storage cotton layer 6, thereby efficiently absorbing the smoke oil for atomization.

[0030] As a necessary component for realizing the function of the electronic cigarette, in this embodiment, the atomizer core 4 is fixedly arranged in the smoke tube 3 and is in direct contact with the oil storage cotton layer 6. This design enables the smoke oil 9 absorbed from the oil storage cotton layer 6 to be directly delivered to the atomizer core 4. The main function of the atomizer core 4 is to heat the absorbed smoke oil 9 and atomize it so that it can be delivered to the user's mouth through the smoke duct 2.

[0031] It should be understood that the automatic oil-refilling electronic cigarette in this embodiment also includes a control mainboard (not shown in the figure), which is responsible for supplying power to the atomizer core 4 and controlling its working state. The control mainboard is connected to a battery, which provides the required power for the entire electronic cigarette, especially the atomizer core 4. By precisely controlling the power output, the atomizer core 4 can work at the optimal temperature to produce the ideal amount and quality of smoke.

[0032] It is understandable that the automatic refilling electronic cigarette of this embodiment realizes the automatic and effective refilling and control of the e-liquid, which significantly improves the smoking experience of the user. At the same time, the design achieves the purpose of reducing costs, facilitating production and maintenance by simplifying the structure and components, and provides a new solution for the electronic cigarette market.

[0033] Although the exemplary embodiments of the present disclosure have been described, it should be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the scope of protection of the present disclosure as defined by the claims. The present disclosure is defined by the appended claims, and the equivalents of these claims are also included.
