Description

Electronic cigarette cartridge sealing structure with fluid check valve, electronic cigarette and application technical field

The disclosure belongs to the field of electronic cigarettes, and in particular relates to an electronic cigarette cartridge sealing structure with a fluid one-way valve, an electronic cigarette and applications.

Background technique

As people are concerned about their own health and environmental pollution caused by smoking. Electronic cigarettes are favored by more and more consumers as a harm reduction alternative to cigarettes. However, e-cigarette products on the market still have the problem of e-liquid leakage, which brings bad experience to consumers. Especially under the condition of high-altitude negative pressure, the leakage of e-liquid is a pain point in the industry. In view of the pain points of the industry, most designers strengthen the sealing design on the oil tank structure when designing the pod structure, and adjust the porosity of the atomizing core, but the problem of oil leakage still exists. The present disclosure adopts a fluid one-way valve sealing structure to solve the problem of oil leakage and oil supply of electronic cigarettes.

The structure of the electronic pod is basically composed of an airflow channel, an atomizing core, an oil tank, a shell and a base. The air channel and the sealed oil tank are connected by an atomizing core. One side of the atomizing core is electronic cigarette liquid, and the other side is connected to the atmosphere through the airflow channel. Improving the oil-locking ability of the atomizing core can improve the oil leakage problem of electronic cigarettes under normal conditions to a certain extent. However, when the outside atmospheric pressure decreases, the pressure difference between the fuel tank and the outside atmospheric pressure increases, and the electronic cigarette oil will leak outward through the atomizing core.

At the same time, in order to solve the problem of oil leakage, most electronic cigarette designers consider strengthening the sealed oil tank to solve the problem of oil leakage. The oil tank will form a negative pressure, and the e-liquid supply speed to the atomizing core will slow down or not flow, and it cannot be pumped. Therefore, the present disclosure uses the fluid one-way valve structure to solve the problem of oil leakage and oil supply of the electronic cigarette.

The technical solutions of the present disclosure will be further described below through specific embodiments and accompanying drawings. It should be noted that the following specific embodiments are only for illustration, and the protection scope of the present disclosure is not limited thereto.

Referring to Figures 1-2, the present disclosure discloses a sealing structure of an electronic cigarette cartridge with a fluid one-way valve. The electronic cigarette cartridge sealing structure is a structure with a one-way valve, and the one-way valve is provided with a fluid one-way valve groove. In this embodiment, the fluid one-way valve is a Tesla valve structure 1, and the Tesla valve 1 is a fixed valve that utilizes a fixed space structure and can allow the fluid to flow in one direction without mechanical activity. The principle of the Tesla valve is that when the fluid flows in the forward direction, the forward flow of the fluid is unimpeded and the total pressure loss is small; but when the fluid flows in the reverse direction, the fluid is repeatedly blocked and shunted and backflowed, hindering the forward flow of the fluid, and the total pressure The losses are extremely large, the fluid outlet pressure drops to near atmospheric pressure, the driving pressure almost disappears, and there is almost no flow.

The Tesla valve 1 is arranged on a sealing part (ie, the electronic cigarette sealing structure body) that blocks the oil tank and the atomization chamber; the oil tank end 2 of the Tesla valve 1 leads to the oil tank, and the atomization chamber end 3 Connected to the atomizing chamber. The direction from the atomization chamber to the oil tank is set as the Tesla valve forward structure. Use the characteristics of the Tesla valve to adjust the balance between the oil tank and the outside atmospheric pressure to ensure smooth oil supply and prevent e-liquid leakage. Specifically, when the e-liquid in the oil tank is consumed, the air pressure in the cabin decreases, and the gas will be quickly introduced into the oil tank through the Tesla valve, so that the air pressure in the oil tank is consistent with the external air pressure, and the oil supply is smooth. The direction from the oil tank to the atomizing chamber is reversed. As the external air pressure becomes lower, the oil tank air pressure is greater than the external air pressure, and the electronic cigarette liquid will be squeezed into the Tesla valve due to the pressure difference. After being consumed, the e-liquid will not flow to the atomizing chamber through the valve body, preventing oil leakage.

At the same time, an e-liquid collecting tank 4 is arranged in the lower section of the sealing structure body of the electronic cigarette, and the e-liquid collecting tank 4 has the function of guiding, collecting and storing the e-liquid. Under the extreme conditions of high-altitude negative pressure, the air pressure of the oil tank is higher than the external pressure, the capillary force of the atomizing core is not enough to lock the e-liquid, and some e-liquid will penetrate into the atomizing cavity through the atomizing core, and the e-liquid collecting tank This part of the e-liquid can be collected and stored to further prevent the e-liquid from leaking through the airflow channel.

In the present disclosure, there are at least three repeating units of the Tesla valve set on the sealing structure body of the electronic cigarette. In this embodiment, there are three repeating units. As shown in FIG. 2 , the groove depth is 0.1 mm to 1 mm, and the groove width is 0.1 mm to 1 mm. 0.1～1mm.

The material used for the sealing structure body of the electronic cigarette cartridge of the present disclosure may be plastic parts, silica gel, metal and other materials, but is not limited thereto. The Tesla valve is set on this part, and then alone or with other parts to form the Tesla valve tube structure, sealing the oil tank and blocking the oil tank and the atomization cavity. In this way, the oil tank in the electronic pod supplies the electronic cigarette liquid to the atomizing core for atomization through the oil guide channel, and the air pressure balance is adjusted between the oil tank and the atomizing chamber through a one-way valve to ensure smooth oil supply and prevent oil leakage due to pressure difference. . The sealing structure of the electronic cigarette cartridge of the present disclosure may be in the shape of a cylinder, a flat cylinder or a rectangular parallelepiped, and is not limited thereto.

To sum up, the sealing structure of the electronic cigarette cartridge with the fluid check valve, the electronic cigarette and the application of the present disclosure have at least one of the following advantages over the prior art:

1. In the present disclosure, by setting the Tesla valve structure on the components that block the oil tank and the atomization cavity, the fluid flow in the positive and negative directions of the Tesla valve is subject to different resistance, and the size of the Tesla valve body is reasonably designed. It can achieve air guiding without oil guiding, and the air pressure of the oil tank can be adjusted in real time along with the positive direction of the suction, and the air pressure of the oil storage chamber can be balanced through the fluid one-way valve to ensure smooth oil supply and prevent oil leakage;

2. The reverse resistance can also be used to consume the pressure difference and solve the problem of improving the high-altitude negative pressure oil leakage of the electronic cigarette;

3. The electronic cigarette cartridge sealing structure body of the present disclosure is also provided with an e-liquid collecting groove, which has the function of guiding, collecting and storing the e-liquid that has penetrated into the atomization cavity, which can further prevent oil leakage.
