Description

Technical Field

[0001] This application relates to the field of electronic cigarettes, in particular to an electronic cigarette with an open oil tank. Background Art

[0002] In the prior art, open oil tank electronic cigarettes have been widely used in the market. This type of electronic cigarette allows users to refuel themselves, providing high convenience and flexibility. However, this design has some obvious deficiencies during actual use. Specifically, when the user opens the oil tank to refuel, the enclosed environment inside the oil tank is destroyed, and the internal pressure tends to be the same as the external pressure. This pressure change causes the e-liquid to flow out through the atomization core, resulting in a significant decline in the user experience.

[0003] In the prior art, the destruction of the enclosed environment of the oil tank not only affects the use effect of the electronic cigarette, but also may cause e-liquid waste and environmental pollution. During the refueling process, users will inevitably encounter the problem of e-liquid leakage, which not only increases the difficulty of cleaning work, but also affects the hygiene and safety of the electronic cigarette. Especially for some high-viscosity e-liquids, the leakage problem is more prominent, not only causing loss of e-liquid, but also may lead to oil accumulation inside the device, affecting the normal operation of the electronic cigarette.

[0004] The main reasons for these deficiencies are that the prior art fails to effectively solve the pressure balance problem during the refueling process of the oil tank. The current designs usually lack an effective pressure regulation mechanism, so that once the oil tank is opened, the internal and external pressures quickly balance, causing the e-liquid to flow out under the pressure change. In addition, the limitations of the atomization core design are also an important factor leading to e-liquid outflow. The atomization core is usually located at the bottom or side of the oil tank. When the oil tank is opened, the e-liquid is likely to flow out through the atomization core under the action of gravity, thus causing leakage problems. Summary of the Utility Model

[0005] The purpose of this application is to at least overcome one deficiency existing in the prior art, and provide an electronic cigarette with an open oil tank, which uses a linkage oil tank switch structure to ensure the stability of the pressure inside the oil tank during the refueling process and avoid the outflow of e-liquid caused by pressure changes.

[0006] To achieve the above purpose, this application discloses an electronic cigarette with an open oil tank, including an electronic cigarette body with an oil tank and a linkage switch member for controlling the opening and closing of the oil tank. Among them, a working channel is provided inside the oil tank of the electronic cigarette body; an annular isolation oil tank that partially surrounds the working channel is provided inside the oil tank; at least one oil supply hole position is provided between the isolation oil tank and the working channel to connect the inner tank and the working channel; an inner hole communicating with the oil tank is opened on the isolation oil tank, and an outer hole for refueling is opened on the oil tank; the linkage switch member cooperates with the inner hole and the outer hole at the same time, and pushing / pulling the linkage switch member can selectively open and close the inner hole and the outer hole.

[0007] Furthermore, the isolation oil tank is located at the bottom of the oil tank.

[0008] Furthermore, the outer hole is located in the upper region of the oil tank.

[0009] Furthermore, the inner hole is arranged near the bottom of the oil tank.

[0010] Furthermore, the linkage switch member includes an outer hole plug located outside the oil tank and cooperating with the outer hole, an inner hole plug located inside the isolation oil tank and cooperating with the inner hole, and a linkage rod connecting the outer hole plug and the inner hole plug.

[0011] Furthermore, the working channel is provided with an atomization assembly that is aligned and cooperates with the fuel supply hole position.

[0012] Furthermore, the atomization assembly includes an atomization core and an oil storage cotton core that surrounds the atomization core and is connected and cooperates with the atomization core.

[0013] Furthermore, a battery for supplying power to the atomization assembly and a control circuit for controlling the operation of the atomization assembly are provided inside the electronic cigarette body.

[0014] Furthermore, a control button for operating the control circuit is provided inside the electronic cigarette body.

[0015] Furthermore, the upper end of the working channel is connected to the mouthpiece located on the electronic cigarette body, and the lower section is directly / indirectly communicated with the external space.

[0016] Optionally, the oil tank has at least one transparent or semi-transparent observation window.

[0017] Optionally, the entire oil tank is transparent.

[0018] Compared with the prior art, in this application, by partially surrounding the working channel and providing a fuel supply hole position to connect the inner cavity and the working channel, and selectively opening and closing the inner hole and the outer hole through the linkage switch member during refueling, the problem of e-liquid leakage during the refueling process is effectively prevented, improving the user experience.

[0027] Such as Figure 1 And 2As shown in the figure, this embodiment discloses an exemplary structure of an electronic cigarette with an open oil tank. In terms of specific structural components, it includes an electronic cigarette body having an oil tank 1 and a linkage switch member 4 for controlling the opening and closing of the oil tank. Inside the oil tank 1 of the electronic cigarette body, there is a working channel 2, and an annular isolation oil tank 3 that partially surrounds the working channel 2 is provided inside the oil tank 1. At least one oil supply hole position is provided between the isolation oil tank 3 and the working channel 2 to connect the inner tank with the working channel 2. An inner hole 6 communicating with the oil tank 1 is opened on the isolation oil tank 3, and an outer hole 7 for refueling is provided in the upper region of the oil tank 1. The linkage switch member 4 cooperates with the inner hole 6 and the outer hole 7 at the same time. Pushing / pulling the linkage switch member 4 can selectively open and close the inner hole 6 and the outer hole 7.

[0028] In this embodiment, the electronic cigarette body further includes a lithium-ion battery for supplying power to the atomization component 5. This battery can be a rechargeable battery and is charged through a USB interface or a dedicated charger. The control circuit is connected to the battery and is used to control the start / stop and working state of the atomization component 5. The control circuit adopts a common circuit design, which is well-known to those skilled in the art and will not be described in detail. The user can operate the control circuit through the control button provided on the electronic cigarette body to realize the control of the atomization component 5.

[0029] The upper end of the working channel 2 is connected to the mouthpiece on the electronic cigarette body, and the lower end is directly or indirectly communicated with the external space. The oil tank 1 has at least one transparent or semi-transparent observation window, or the oil tank 1 is designed to be entirely transparent, enabling the user to directly observe the amount of e-liquid in the oil tank 1 and prevent dry burning.

[0030] The refueling process is specifically described as follows: When the user needs to refill the oil tank 1, first push and pull the linkage switch member 4 to close the inner hole 6, ensuring that the inner hole 6 is sealed and isolated from the isolation oil tank 3 and the working channel 2. At this time, the outer hole 7 is opened, and the user can perform the refueling operation through the outer hole 7. Since the e-liquid stored in the isolation oil tank 3 is sealed and isolated from the working channel 2, the air pressure change inside the oil tank 1 will not affect the flow of the e-liquid in the isolation oil tank 3, ensuring that the e-liquid will not flow into the working channel 2 through the oil supply hole position during refueling and avoiding e-liquid leakage.

[0031] Specifically, the user picks up the electronic cigarette, turns the outer hole 7 upward, closes the inner hole 6 and opens the outer hole 7 by pushing and pulling the linkage switch member 4, inserts the oil bottle nozzle and slowly injects the e-liquid into the outer hole 7 until the oil tank 1 is full. After refueling, the user pushes and pulls the linkage switch member 4 again to close the outer hole 7 and open the inner hole 6, so that the e-liquid stored in the isolation oil tank 3 enters the working channel 2 through the oil supply hole position for use by the atomization core 501. This process ensures the sealed isolation between the oil tank 1 and the working channel 2, preventing the e-liquid in the oil tank 1 from leaking to the outside or flowing into the working channel 2 during refueling.

[0032] During normal use, the atomization component 5 sucks e-liquid from the working channel 2 through the wicking core 502, and the atomization core 501 atomizes the absorbed e-liquid into vapor for the user to inhale. Based on capillary action, the wicking core 502 can effectively absorb and store e-liquid, ensuring the stability and continuity of the atomization process. When the e-liquid in the working channel 2 is gradually consumed, the e-liquid in the isolation oil reservoir 3 is replenished into the working channel 2 through the oil supply hole positions, ensuring that the atomization component 5 continuously obtains e-liquid.

[0033] It should be understood that during daily use, since a negative pressure is formed in the oil reservoir 1 after the e-liquid flows out, which prevents the e-liquid from flowing out continuously. Therefore, in actual use, the user needs to manually operate the linkage switch 4 at regular intervals to open the outer hole 7 once or multiple times to compensate for the negative pressure in the oil reservoir 1 and ensure that the e-cigarette can continue to replenish oil smoothly. At least the inner hole plug 8 and the outer hole plug 9 in the push-pull linkage switch 4 are made of silica gel, which can well seal the holes and ensure the sealing and safety of the oil reservoir 1 during use.

[0034] This embodiment not only improves the user experience, reduces the waste of e-liquid and environmental pollution, but also enhances the sealing and reliability of the e-cigarette. The transparent or semi-transparent observation window design enables the user to monitor the oil level at any time, preventing dry burning and further enhancing the safety and reliability of the e-cigarette. In addition, through the optimized structural design, the e-cigarette can atomize e-liquid more efficiently, improving the atomization effect and service life. Considering the specific use scenario, for example, when e-liquid needs to be replenished after long-term use, this design ensures a simple and leak-free oil replenishment process, providing a better user experience and device protection.

[0035] Although the exemplary embodiments of the present disclosure have been described, those skilled in the art should understand 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 protection scope of the present disclosure defined by the claims. The present disclosure is defined by the appended claims, and equivalents of these claims are also included.
