In addition, the current method for atomizing the tobacco tar on the market basically heats the oil guide rope soaked with the tobacco tar directly by a heating wire. The oil guide rope is always in a smoke oil soaking state. Along with calorific capacity increase, the oil guide rate of leading the wick does not follow up, and the temperature of heating wire subassembly will rise, and when the temperature was high to a certain degree, the wick can high temperature deteriorate, and tobacco tar can high temperature burning, can send the flavor of scorching. The risk that the oil guide rope is carbonized in the later stage of pumping can influence the oil supply of the oil guide rope and the pumping experience. In addition, the tobacco tar is soaked in the oil guiding rope all the time, the atomization amount of the tobacco tar cannot be controlled, and the smoking experience of consumers is influenced.
