The electronic atomization technology is a technology that applies electricity to heat a liquid to a boiling point for evaporation to generate atomized vapor and is currently mostly applied to the field of electronic atomizers. With the innovation and progress of the atomization technology, the electronic atomization technology is being applied to various other fields, such as fields of beauty care and medical care. In the field of atomization technology, the most commonly known concern is liquid leaking.

In brief, liquid leaking is a fatal issue for atomizers, and as such, it is desired to develop a reliable and perfect atomizer structure to avoid the occurrence of such an issue. At present, the known techniques mostly adopt immersing a liquid-conducting member of an atomizer in an atomizable liquid or arranging a liquid feeding opening to control a liquid feeding amount, or the atomizable liquid is kept from contacting the liquid-conducting member when not in use, and during the course of use, the liquid-conducting member is held in a state of being persistently contacting with the liquid stored in a liquid storage compartment.

The sealing memberis formed with a gas conducting holethrough which an atomized gas is conducted out, at least one liquid ingress one-way valveand at least one gas ingress one-way valve. The liquid ingress one-way valvecontrols the liquid of the liquid storage compartment I to move, in a one-way manner, into the atomization unitfor atomization. The gas ingress one-way valveis connected to the gas supply unitto supply gas, in a one-way manner, into an interior of the liquid storage compartment.

The liquid storage compartmentmainly functions to store and hold the atomizable liquid. The sealing memberhermetically closes the liquid storage compartment, so that in a condition of being not used, the atomizable liquid in the liquid storage unitis not in direct contact engagement with and the atomization unit. The atomization unitmainly functions as essential hardware for atomization of the atomizable liquid. The atomization unitcomprises a liquid-conducting body, and a heat-generating bodywrapping around an outside wall of the liquid-conducting body. The liquid-conducting bodyis arranged to correspond to a bottom of a liquid egress end of the liquid ingress one-way valve, and mainly functions to heat the atomizable liquid to a boiling point to form atomized vapor.

In the course of use of the electronic atomizer, when in operation, the control unitcontrols the gas supply unitto open up and the gas supply unitgenerates gas to supply the gas to the site of the gas ingress one-way valveof the liquid storage unit, so that a gas pressure at the site of the gas ingress one-way valveof the liquid storage unitis increased, and the increased gas pressure pushes open the gas ingress one-way valveof the sealing memberto allow the gas to get into the interior of the liquid storage compartment, thereby increasing a gas pressure in the interior of the liquid storage compartment, and the gas pressure, when increased to a predetermined level, becomes compressing the atomizable liquid to thereby push open the liquid ingress one-way valveto allow the atomizable liquid in the interior of the liquid storage compartmentto pass through the liquid ingress one-way valveand be conducted to the atomization unit, and the control unitcontrols the operation of the atomization unitto have heat generated in the atomization unitatomizing the atomizable liquid to form atomized vapor, and the atomized vapor is mixed with air that gets into the atomization unitto form an aerosol (atomized gas), and the atomized gas flows out by way of the gas conducting holeof the sealing member; when not in operation, the gas ingress one-way valveis in a closed state, and the liquid ingress one-way valveis also in a closed state, and the gas pressure of the atomization unitand the gas pressure in the interior of the liquid storage unitare generally in a balanced state, and the atomizable liquid in the liquid storage compartmentdoes not flow to the atomization unit.

The atomization unitis arranged to correspond to a liquid egress end of the liquid ingress slitof the liquid ingress valve core. It is appreciated that the liquid ingress portionis in communication with the atomizable liquid of the liquid storage compartment. The liquid ingress valve corecontrols opening and closing of the liquid ingress one-way valve.

Further, preferably, in the sealing member, at least the liquid ingress valve coreis a component made of an elastic material. The liquid ingress valve coreis exposed at the side associated with the atomization unit. When the electronic atomizer is not in operation, the liquid ingress valve coreis acted upon by a reverse pressure, and the liquid ingress valve coreis flatter than the liquid ingress portion, and side walls of the liquid ingress valve coreare compressed by the air pressure at the side associated with the atomization unit, and the pressure acting at the site of the liquid ingress slitis almost negligible, so that the liquid ingress slitof the liquid ingress valve coreis caused to close more tightly; and when the electronic atomizer is in operation, the gas supply unitfeeds gas into the interior of the liquid storage compartment, and the internal pressure of the liquid storage compartmentis increased, and the pressure compresses the atomizable liquid in the interior of the liquid storage compartmentto thereby lead to a trend for the atomizable liquid to flow out of the liquid storage compartment, and when the gas pressure in the interior of the liquid storage compartmentbecomes excessively large, the pressure at the site of the liquid ingress portioncompresses the atomizable liquid to thereby open up the liquid ingress slitof the liquid ingress valve core, so that the atomizable liquid can be conducted into the atomization unitto be atomized by the atomization unit.

Further, preferably, in the sealing member, at least the gas ingress valve coreis a component made of an elastic material. The gas ingress valve coreis exposed at the side associated with the liquid storage unit, and the gas ingress valve coreis flatter than the gas ingress portion. When the electronic atomizer r is not in operation, the gas ingress valve coreis acted upon by a reverse pressure, and side walls of the gas ingress valve coreare compressed by the liquid pressure at the side associated with the liquid storage unit, and the pressure acting at the site of the gas ingress slitis almost negligible, so that the gas ingress slitof the gas ingress valve coreis caused to close more tightly, and when the electronic atomizer is in operation, the gas supply unitoperates and the gas supply unitgenerates gas, and the pressure at the site of the gas ingress portionand the gas ingress valve coreis gradually increased, and the pressure compresses the liquid ingress valve coreto thereby lead to a trend for the gas generated by the gas supply unitto flow into the liquid storage compartment, and when the gas pressure at the site of the gas ingress portionand the gas ingress valve coreis increased to a predetermined level, the pressure pushes open the gas ingress slitof the gas ingress valve core, so that the gas generated by the gas supply unitmay get into the interior of the liquid storage unitto thereby increase the gas pressure in the interior of the liquid storage compartment, and the gas pressure, when increased to a predetermined level, compresses the atomizable liquid to push open the liquid ingress slitof the liquid ingress valve core, thereby allowing the atomizable liquid to be conducted into the atomization unitto be atomized by the atomization unit.
