Description

Technical Field

[0001] The present invention relates to the technical field of electronic cigarette auxiliary tools, and in particular to a tobacco paste cutting device and a control circuit and a control method thereof. Background Art

[0002] The e-cigarette paste is a solid paste. Compared with e-liquid, it is easy to carry and will not overflow or inhale when used, so it is widely used. The common e-cigarette paste cutting and picking tools on the market generally use ear spoons, picking needles, knives, etc. without heating functions. When cutting and picking up e-cigarette paste, the e-cigarette paste will adhere to these tools due to its stickiness, resulting in many inconveniences when using it: 1. Because the e-cigarette paste is hard, it requires a lot of force when cutting; 2. Because the e-cigarette paste and the tool are attached, it is impossible to achieve effective and accurate cutting. After picking up, the e-cigarette paste must be separated from the tool by scraping. The scraped e-cigarette paste often adheres to the side wall of the atomizer core and cannot accurately fall into the bottom of the heating core. This causes a waste of resources on the one hand, and on the other hand, it is easy to cause the heating surface of the atomizer to have no e-cigarette paste, resulting in empty burning and damage to the equipment.
