Description
Technical Field
The invention belongs to the field of electronic cigarettes, and particularly relates to an electronic cigarette cartridge sealing structure with a fluid one-way valve, an electronic cigarette and application.
Background
Along with the concern of people on self health and environmental pollution caused by smoking. Electronic cigarettes are gaining increasing popularity as a harm-reducing alternative to cigarettes. However, the electronic cigarette products in the market still have the problem of electronic cigarette oil leakage, which brings bad experience to consumers. The tobacco tar leakage is an industrial pain point especially under the condition of high altitude negative pressure. Aiming at the industry pain point, most designers strengthen the sealing design on the oil bin structure when designing the smoke cartridge structure, and adjust the porosity of the atomizing core, but the oil leakage problem still exists. The invention adopts the fluid one-way valve sealing structure to solve the problem of oil leakage and oil supply of the electronic cigarette bomb.
The electronic cigarette cartridge is basically composed of an airflow channel, an atomizing core, an oil bin, a shell and a base. The airflow channel and the sealed oil bin are connected by the atomizing core. One side of the atomization core is electronic cigarette liquid, and the other side of the atomization core is communicated with the atmosphere through an airflow channel, so that the oil locking capacity of the atomization core is improved, and the problem of oil leakage of the electronic cigarette in a normal state can be improved to a certain extent. However, when the outside atmospheric pressure is reduced, the pressure difference between the oil bin and the outside atmospheric pressure is increased, and the electronic cigarette oil can leak outwards through the atomizing core, which is also a common reason for the oil leakage of the electronic cigarette carried by high altitude negative pressure (taking an airplane).
Simultaneously, in order to solve the oil leak problem, most electron cigarette designers all consider to strengthen sealed oil bin and solve the oil leak problem, and this will cause in the use, along with the reduction of tobacco tar, if do not have the outside gas to supply into, the oil bin can form the negative pressure, and the electron tobacco tar slows down or does not flow to atomizing core fuel feeding speed, can't aspirate. Therefore, the invention solves the oil leakage and supply problem of the electronic cigarette bomb by using the fluid one-way valve structure.

The technical solution of the present invention is further illustrated by the following specific embodiments in conjunction with the accompanying drawings. It should be noted that the following specific examples are given by way of illustration only and the scope of the present invention is not limited thereto.
Referring to fig. 1-2, the present invention discloses an electronic cigarette cartridge sealing structure with a fluid check valve. The electronic cigarette bullet sealing structure is a structure with a one-way valve, and a fluid one-way valve groove is formed in the one-way valve. In this embodiment, the fluid check valve is a tesla valve structure 1, and the tesla valve 1 is a fixed valve that can make fluid flow in one direction without mechanical movement by using a fixed space structure. The Tesla valve has the principle that when fluid flows forwards, the fluid flows forwards unimpededly, and the total pressure loss is small; however, when the fluid flows in the reverse direction, the fluid is repeatedly blocked, shunted and refluxed, the fluid is blocked from flowing forwards, the total pressure loss is extremely large, the outlet pressure of the fluid is reduced to be close to the atmospheric pressure, the driving pressure is almost disappeared, and the fluid hardly flows.
The Tesla valve 1 is arranged on a sealing component (namely an electronic cigarette cartridge sealing structure body) for obstructing the oil bin and the atomizing cavity; an oil bin end 2 of the Tesla valve 1 is communicated with an oil bin, and an atomizing cavity end 3 is connected with an atomizing cavity. The direction from the atomizing cavity to the oil bin is set to be a forward structure of a Tesla valve. By utilizing the characteristic of the Tesla valve, the balance between the oil bin and the external atmospheric pressure is adjusted, the smoothness of oil supply is ensured, and the electronic cigarette liquid is prevented from leaking. Specifically, when the electronic cigarette liquid in the oil bin is consumed, the air pressure in the oil bin is reduced, the air can be quickly led into the oil bin through the Tesla valve, the air pressure of the oil bin is kept consistent with the air pressure outside, and smooth oil supply is guaranteed. The direction from the oil bin to the atomizing cavity is reverse, the air pressure of the oil bin becomes lower than the external air pressure, the electronic cigarette liquid can be squeezed into the Tesla valve due to the pressure difference, the electronic cigarette liquid can not flow to the atomizing cavity through the valve body after being dispersed through multiple times of backflow, and oil leakage is prevented.
Meanwhile, the lower section of the electronic cigarette bullet sealing structure body is provided with a tobacco tar collecting groove 4, and the tobacco tar collecting groove 4 has the functions of guiding, collecting and storing tobacco tar. When under high altitude negative pressure limit condition, oil bin atmospheric pressure is higher than ambient pressure, and the capillary force of atomizing core is not enough to pin the tobacco tar, and some tobacco tar can permeate the atomizing chamber through the atomizing core, and the tobacco tar collection groove can collect this part of tobacco tar and store, further prevents that the tobacco tar from passing through the air flow channel weeping.
The number of the repeating units of the Tesla valve arranged on the electronic cigarette cartridge sealing structure body is at least 3, the embodiment is three repeating units, and as shown in figure 2, the depth of a groove is 0.1-1 mm, and the width of the groove is 0.1-1 mm.
The electronic cigarette cartridge sealing structure body can be made of plastic parts, silica gel, metal and other materials, but is not limited to the materials. The Tesla valve is arranged on the component, and then the Tesla valve is used alone or matched with other components to form a Tesla valve tube body structure, so that the oil bin is sealed, and the oil bin and the atomizing cavity are blocked. Therefore, the oil bin in the electronic cigarette bomb supplies the electronic cigarette liquid to the atomizing core for atomization through the oil guide channel, the air pressure balance between the oil bin and the atomizing cavity is adjusted through the one-way valve, the smooth oil supply is ensured, and the oil leakage caused by pressure difference is also prevented. The sealing structure of the electronic cigarette cartridge of the present invention may be cylindrical, flat cylindrical or rectangular, but is not limited thereto.
It should be noted that, although the invention has been shown and described with reference to the specific exemplary embodiments thereof, it should be understood by those skilled in the art that the present invention is not limited to the above-mentioned embodiments, and various changes and modifications may be made therein without departing from the spirit and scope of the invention, and it is intended that the invention encompass such changes and modifications as fall within the scope of the claims and the equivalent technical scope of the invention.
In particular, various combinations and/or combinations of features recited in the various embodiments and/or claims of the present invention can be made without departing from the spirit and teachings of the invention, even if such combinations or combinations are not explicitly recited in the present invention.
