Description

Technical Field

[0001] The present invention relates to the technical field of electronic cigarettes, and in particular to an oil storage atomization component and an electronic cigarette that controls oil intake. Background Art

[0002] Electronic cigarettes are tobacco substitutes that form steam aerosol smoke particles for users to inhale by electrically heating the smoke oil. Its core components include but are not limited to a shell, an oil storage tank, an atomizer core, a battery and a control panel. Among them, an atomizer core is axially arranged in the oil storage tank, and the upper end of the oil storage tank is connected to the suction nozzle and the hollow channel of the atomizer core. The lower end of the oil storage tank is an oil seal element that seals the lower inner wall of the oil storage tank and the outer wall of the atomizer core. This is a bright oil type electronic cigarette oil storage atomizer assembly, and its atomizer core is always immersed in the smoke oil. The smoke oil is introduced into the oil guide cotton in the atomizer core through the oil inlet hole on the side wall of the atomizer core assembly. The oil guide cotton is wrapped with an electric heating wire. This bright oil type electronic cigarette oil storage atomizer assembly is easy to overflow from the hollow channel of the atomizer core when the pressure difference between the internal and external oil pressure is large. The outer wall of the atomizer core assembly transfers heat and directly contacts the smoke oil, which is easy to cause oxidation reaction, discoloration, and taste change of the smoke oil.

[0003] The existing cotton-immersed oil storage atomization component that uses polymer oil storage integrated cotton as a way to absorb and lock the smoke oil has an oil storage integrated cotton in the oil cup. The oil storage integrated cotton is provided with a hollow space that runs through it from top to bottom, and an atomization core is provided in the hollow space. The smoke oil is injected into the oil storage integrated cotton for absorption. When in use, the suction nozzle generates a negative pressure in the atomization core, thereby sucking the smoke oil of the oil storage integrated cotton to the electric heating wire of the atomization core to achieve atomization. The oil storage integrated cotton has a certain oil locking property. Compared with the open oil type electronic cigarette, it is less likely to overflow oil, but it is not completely free of oil overflow, such as when the amount of oil absorbed by the oil storage integrated cotton is large. Similarly, the oil storage integrated cotton type electronic cigarette oil storage atomization component, the smoke oil is immersed in the oil storage integrated cotton for a long time. The smoke oil contains PG, VG and various flavors and additives. These organic substances will undergo slow chemical reactions, including alcoholization reactions and oxidation reactions. If the e-liquid is soaked in the oil storage cotton for a long time, especially if the fibers of the oil storage cotton are arranged loosely, the oil conductivity and oil storage are good, the e-liquid is more likely to come into contact with the air and undergo oxidation reaction, causing the e-liquid to deteriorate. For the design of the above-mentioned electronic cigarette oil storage atomization component, further research and development is needed to overcome the above-mentioned technical problems. Summary of the invention

[0004] In view of this, the present invention proposes an oil storage atomization component and an electronic cigarette for controlling the oil intake, so as to solve the problems of oil seepage and leakage in the hollow atomization channel of the electronic cigarette atomization core in the prior art, and the long-term deterioration and staleness of the cigarette oil.

[0012] Furthermore, the first through hole port is a hollow tube portion extending from the upper end of the first shell toward the first opening, the hollow tube portion is sleeved with a silicone seal, and the second through hole port of the second shell is inserted into the silicone seal to achieve a sealed connection between the outer wall of the hollow tube portion and the inner wall of the second through hole port, so as to prevent smoke oil from entering from the second through hole port.

[0013] In one embodiment, a suction nozzle portion formed integrally with the first shell is provided at the upper end of the hollow tube portion.

[0014] In one of the solutions, an independent suction nozzle component which is a separate component is inserted into the upper end of the hollow tube.

[0021] The oil storage atomization assembly and electronic cigarette designed by this technical solution have the following beneficial effects: the oil storage atomization assembly disclosed in this solution is also called an oil cup or a smoke cartridge in electronic cigarette products, and its core innovation lies in that the smoke oil in the oil storage chamber of the oil cup or the smoke cartridge is not directly adsorbed by the oil storage integrated cotton, nor is the atomization core directly immersed in the smoke oil. It forms an oil storage integrated cotton disposed outside the atomization core, and a second shell is disposed outside the oil storage integrated cotton. The core is designed with multiple hollow chambers around the second shell near the lower end, and a floating part is arranged in the hollow chamber, which enters the hollow chamber through the oil storage chamber, and then enters the oil storage integrated cotton from the hollow chamber. When the oil storage integrated cotton no longer absorbs smoke oil, the smoke oil enters the hollow chamber and causes the floating part to float up, and the floating floating part just blocks the first oil inlet hole of the hollow chamber. Therefore, the smoke oil in the oil storage chamber will not enter the hollow chamber. When the smoke oil absorbed by the oil storage integrated cotton is consumed to a certain amount, the oil storage integrated cotton absorbs the smoke oil in the hollow chamber again, and the amount of smoke oil in the hollow chamber decreases, causing the floating part to drop. At this time, the floating part no longer blocks the first oil inlet hole, and the smoke oil in the oil storage chamber enters the hollow chamber again. When the oil storage integrated cotton no longer absorbs the smoke oil, the smoke oil enters the hollow chamber again, causing the floating part to float up, and the floating floating part blocks the first oil inlet hole of the hollow chamber again, and so on. First, the electronic cigarette smoke oil is isolated and stored in the oil storage chamber, which is not easily affected by the temperature generated by the operation of the atomizer core. Second, a certain amount of smoke oil is controlled to enter the oil storage integrated cotton for absorption, and the oil storage integrated cotton has a small amount of smoke oil, and the atomizer core is not easy to overflow. Third, after the electronic cigarette consumes part of the smoke oil of the oil storage integrated cotton, it will absorb the smoke oil in the hollow chamber for replenishment, which is conducive to maintaining the freshness of the electronic cigarette smoke oil and improving the consistency of the taste of the electronic cigarette.
