[0048] like Figure 1-6 As shown, the embodiment of the utility model provides an atomizer, the atomizer comprising:

[0049] A liquid storage component 1, wherein a liquid storage cavity is constructed therein;

[0050] An atomizing bracket 2 is disposed in the liquid storage chamber, wherein an atomizing chamber connected to the liquid storage chamber is constructed in the atomizing bracket 2, and an air inlet and an air outlet of the atomizing chamber are both connected to the outside of the liquid storage assembly 1;

[0051] The liquid storage core tube 3 is arranged in the atomization chamber;

[0052] An atomizing core tube 4 is arranged in the liquid storage core tube 3;

[0053] A heating element 5 is disposed in the atomizing core tube 4;

[0054] The atomizing bracket 2 is provided with a liquid separation chamber 21 which is in communication with the liquid storage core tube 3 .

[0055] In this embodiment, the atomizer includes a liquid storage component 1, an atomizing bracket 2, a liquid storage core tube 3, an atomizing core tube 4 and a heating element 5; specifically, a liquid storage cavity is constructed in the liquid storage component 1; the atomizing bracket 2 is arranged in the liquid storage cavity, and an atomizing cavity connected to the liquid storage cavity is constructed in the atomizing bracket 2, and an air inlet and an air outlet of the atomizing cavity are both connected to the outside of the liquid storage component 1; the liquid storage core tube 3 is arranged in the atomizing cavity; the atomizing core tube 4 is arranged in the liquid storage core tube 3; and the heating element 5 is provided. The heating element 5 is arranged in the atomizing core tube 4; the atomizing bracket 2 is provided with a liquid separation cavity 21 which is in communication with the liquid storage core tube 3. The liquid storage cavity is in communication with the atomizing cavity, and the atomized liquid in the liquid storage cavity can be transported to the liquid storage core tube 3 in the atomizing cavity, and then transported to the atomizing core tube 4 through the liquid storage core tube 3. The atomized liquid on the atomizing core tube 4 is heated by the heating element 5 to generate an aerosol, and the aerosol flows out of the air outlet along with the air flow flowing into the air inlet of the atomizing cavity, and is finally inhaled by the user. When the external environment changes or the atomized liquid in the liquid storage chamber of the liquid storage component 1 exerts a greater pressure on the liquid storage core tube 3 and the atomization core tube 4, the pressure in the liquid storage chamber of the liquid storage component 1 is higher than the external pressure. At this time, the pressure in the liquid storage component 1 is greater than the liquid locking ability of the liquid storage core tube 3 and the atomization core tube 4, and the atomized liquid will be pressed out and leak out from the air inlet or air outlet of the atomization chamber, resulting in liquid leakage.

When the external environment changes or the atomized liquid in the liquid storage chamber of the liquid storage component 1 exerts a greater pressure on the liquid storage core tube 3 and the atomization core tube 4, the atomized liquid can be temporarily stored in the liquid separation chamber 21 to prevent leakage. After the heating element 5 fully atomizes the atomized liquid on the atomization core tube 4, the atomization core tube 4 will absorb the liquid in the liquid separation chamber 21, and then atomize it again through the heating element 5, thereby achieving the purpose of preventing liquid leakage.

If the atomizer leaks, the leaked liquid passes through the liquid storage core tube 3 to the liquid separation chamber 21 arranged at the upper end and / or lower end of the atomizing chamber. During suction, the atomized liquid in the liquid separation chamber 21 is absorbed by the liquid storage core tube 3 and heated and atomized again by the heating element 5 to reduce or completely absorb the atomized liquid in the liquid separation chamber 21, thereby achieving the purpose of preventing liquid leakage.
