[0002] Existing electronic cigarette devices basically have an oil-absorbing cotton inside the mouthpiece to filter the atomized matrix. However, the oil-absorbing cotton inside the mouthpiece cannot be replaced. As the use time increases, the oil-absorbing cotton is filled with the atomized matrix, thereby reducing its oil absorption efficiency. Alternatively, when the oil-absorbing cotton is filled with the atomized matrix, the atomized matrix in the oil-absorbing cotton flows out when the user inhales, and is sucked into the mouth, affecting the taste.
