The tobacco pot is divided into a first pot body and a second pot body. The second pot body is communicated with the preheating passage. The heating element is arranged in the preheating passage. The filter assembly is removably installed in the second pot body and can be pushed into the second pot body again through the first pot body after being removed. During smoking, external air flow enters the preheating passage, and then the preheating passage discharges hot air to the second pot body, such that heat is uniformly sent into the first pot body to evaporate substance to be evaporated after passing through the filter assembly. Such design can improve air preheating efficiency while ensuring convenient cleaning.
