CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a national stage filing under 35 U.S.C. § 371 of international application number PCT/CN2020/106675, filed Aug. 4, 2020, which claims priority to Chinese patent application No. 202010060769.8 filed Jan. 19, 2020. The contents of these applications are incorporated herein by reference in their entirety.

TECHNICAL FIELD

The disclosure relates to the field of electronic technologies, and more particularly, to an atomizer having an air pressure surge bin and an application thereof.

BACKGROUND

In 1963, Gilbert, an American engineer, applied for and obtained a patent of “smoke-free and non-tobacco cigarette”, which provided a technical solution of smoking without burning tobacco leaves and cigarette paper, and through a safe and harmless smoking device, moist and fragrant smoke heated could be directly inhaled into lungs of a user. In 2003, Li Han, a Chinese pharmacist and former deputy director of Liaoning Institute of Traditional Chinese Medicine, applied for and obtained an invention patent of “non-combustible electronic atomization cigarette”. In 2004, Ruyan Company founded by Li Han sold the world's first electronic cigarette.

The electronic cigarette is mainly composed of a cigarette rod with a battery and a chip, an atomizer, and a cartridge/e-liquid. Operating principle of the electronic cigarette is described below. Operating state of the electronic cigarette is controlled by an air switch controller (an airflow sensor) inside the battery. When smoking, a switch is turned on, the battery supplies power to an electric heating wire in the atomizer, the electric heating wire heats up to atomize the e-liquid attached around the electric heating wire, and generated smoke enters a mouth of a user along with an airflow, thus completing the simulation of a real smoking process. The atomizer, as the most important component of the electronic cigarette, includes an inner core heating wire, a tobacco juice bin (also called an e-liquid bin), and an air inlet hole, so as to ensure the successful completion of an atomization process.

According to the electronic cigarette, the e-liquid is usually heated and atomized by the atomizer to give out smoke for a smoker to use, and according to the electronic cigarette, the smoke is generally stored in the atomizer. Due to the high power of the electric heating wire and the large amount of heat emitted, the existing electronic cigarette with a large amount of smoke is prone to burning loss due to overhigh temperature of an atomization seat, generate scorching smell in the smoke, and lead to a hot outer shell of the electronic cigarette due to heat conduction, thus giving bad use experience to a user, and causing e-liquid leakage.

Chinese patent publication No. 201710631499.X, entitled “electronic cigarette atomizer and electronic cigarette”, filed Jul. 28, 2017, has an operating principle as follows. A spiral electric heating wire 28 is vertically arranged on an atomization seat 25 and a liquid guiding core 27 is wrapped outside the electric heating wire 28, so that air flows through a spiral through hole of the electric heating wire 28, the spiral through hole forms an atomization chamber for atomizing the e-liquid. Since a cross section of the spiral through hole and an inner wall of the spiral through hole have a larger area, an air flux and an atomization area can be increased, so that air may be fully contacted with the e-liquid on the liquid guiding core 27, and a large amount of smoke can be generated when the power of the electric heating wire 28 is large enough.

When the power of the electric heating wire 28 is large, a lot of heat will be inevitably generated, and excess heat that has not been absorbed by the e-liquid will be transferred to the atomization seat 25 and an outer shell of the atomizer, resulting in high temperature. In a case of smoking for a long time, the liquid guiding core may be scorched and related parts of the atomizer may be burned and damaged, and it is easy to result in bad smoking experience to the smoker, such as scorching smell in the smoke and hot feeling on the electronic cigarette held.

Therefore, an air inlet groove 251 and a liquid inlet groove 255 are arranged on an outer wall of the atomization seat 25, which enables low-temperature air entering the atomizer to flow through the outer wall of the atomization seat 25 first to take away excess heat on the atomization seat 25 for cooling. Meanwhile, the low-temperature e-liquid before entering the liquid guiding core 27 flows through the outer wall of the atomization seat 25 first to take away excess heat from the atomization seat 25 to reduce the temperature, and the e-liquid is also preheated to make the e-liquid easier to flow and be atomized.

However, it is obvious that the structure of the air inlet groove and liquid inlet groove set by the above patented technology cannot solve the problems of heat dissipation and e-liquid leakage of the atomizer at the same time. Therefore, it is necessary to further improve the prior art.

By arranging the air pressure surge bin 202 on the atomizer, excessive smoke can converge in the air pressure surge bin 202, thus preventing the outer shell of the electronic cigarette from being hot and bringing bad use experience to the user. The atomization seat 20 is provided with the first sealing rubber ring 801, the second sealing rubber ring 802 and the e-liquid return opening 210, the e-liquid leaking from the first sealing rubber ring 801 can return to the air pressure surge bin 202 from the e-liquid return opening 210, and the second sealing rubber ring 802 can also prevent the e-liquid that leaks from the first sealing rubber ring 801 from leaking out of the atomization seat 20, so that the atomizer can prevent the e-liquid from leaking out, thus improving operating effect and service life of the atomizer.
