Electronic atomizer

An electronic atomizer, comprising:

• a housing, provided with a first accommodating cavity, a second accommodating cavity, and an assembly cavity, wherein the first accommodating cavity extends facing an end part of the housing to form a first opening, the second accommodating cavity extends facing the end part of the housing to form a second opening, and the assembly cavity extends facing the end part of the housing to form a third opening;
• a cigarette paste cup and a paste cutting knife, wherein the cigarette paste cup is disposed in the first accommodating cavity through the first opening, and the paste cutting knife is disposed in the second accommodating cavity through the second opening;
• an atomization device, disposed in the assembly cavity through the third opening, wherein a first air passage being disposed in the assembly cavity, one end of the first air passage is communicated with the atomization device, and the other end of the first air passage extends to a second end of the housing to form an air inlet hole;
• a mouthpiece, detachably disposed on the housing, and communicated with a flue of the atomization device;
• a main board and a first battery, wherein the main board and the first battery are respectively disposed in the assembly cavity, the first battery is electrically connected to the main board;
• and
• wherein a side wall of the paste cutting knife is provided with a first elastic contact point;
• a side wall of the first accommodating cavity is provided with a second elastic contact point;
• the second elastic contact point is electrically connected to the main board;
• and when the paste cutting knife is placed in the second accommodating cavity, the first elastic contact point is in contact with the second elastic contact point to charge the paste cutting knife.
