The pressure regulating assembly 30 may be composed of a piston and an elastic member, or may be an elastic body, an elastic membrane or a hollow elastic body, and the structure, the arrangement manner and the pressure relief principle are the same as those of the above embodiments, and are not described herein again.

Please refer to fig. 9, which is a schematic structural diagram of an electronic atomizer according to the present invention.

In the present embodiment, the electronic atomization device includes a cartridge 1 and a power supply unit 2 for supplying power to the cartridge 1. The cartridge 1 may implement any of the embodiments described above and will not be described in detail herein. The power supply assembly 2 comprises a battery and a control circuit for controlling the working state of the cartridge 1. The battery can be lead accumulator, lead crystal battery or dry battery, only need satisfy the electron atomizing device can normally work, this application does not limit to this.

The utility model discloses a set up trompil 111 on atomizing seat 11, set up pressure regulating assembly 30 in the contact department of stock solution storehouse 20 and trompil 111, make under the high temperature high pressure condition, the gas in the stock solution storehouse 20 takes place to expand, pressure regulating assembly 30 is through sliding, elastic contraction or inflation in order to increase the volume of stock solution storehouse 20, realize to the stock solution storehouse 20 pressure release, the pressure release can reduce or avoid the impact of the internal pressure of stock solution storehouse 20 to the direct contact seal area, thus realize the leak protection liquid; when the temperature and pressure in the liquid storage bin 20 are recovered to normal, the pressure regulating assembly 30 is recovered to the original state. Meanwhile, liquid in the liquid storage bin 20 is consumed, the internal pressure of the liquid storage bin 20 is reduced when the liquid cannot be supplemented, and the pressure regulating assembly 30 is elastically contracted or expanded to reduce the volume of the liquid storage bin 20, so that the dry burning phenomenon of the atomizing core 12 can be avoided.

The above only is the partial embodiment of the present invention, not therefore the limitation of the protection scope of the present invention, all the uses of the equivalent device or equivalent flow transformation made by the contents of the specification and the drawings, or the direct or indirect application in other related technical fields, all the same principles are included in the patent protection scope of the present invention.
