[0046] For example, in use, the pumping assembly 300 is pressed to generate negative pressure in the pumping assembly 300, so that the tobacco juice in the oil storage compartment 501 can be sucked into the pumping assembly 300 and then delivered to the atomization assembly 200 through the pumping assembly 300, so that the atomization assembly 200 can atomize the tobacco juice in the atomization assembly 200. When not in use, the pumping assembly 300 can be restricted to prevent the tobacco juice in the oil storage compartment 501 from flowing into the atomization assembly 200 or leaking, so that the tobacco juice in the atomization assembly 200 can be fully utilized each time, reducing the use cost, and the structure is simple and convenient to use.

[0047] Therefore, the present application can introduce the oil storage compartment 501 into the atomization assembly 200 through the pumping assembly 300, and can supply oil to the atomization assembly 200 through the pumping assembly 300 only when the consumer smokes, thereby solving the problem that the tobacco juice is easily volatile due to long-term storage in the atomization compartment of the atomization assembly 200, and improving the corrosion or flavor change of the atomization core 201 in the atomization assembly 200 due to long-term soaking in the tobacco juice, thereby ensuring the freshness and purity of the tobacco juice before use.
