Further, considering that under the effects of high temperature, vibration and other factors, the pressure is increased due to the expansion of the gas in the bottle body 200, the aromatherapy liquid may overflow from the aromatherapy bottle 10 under the effect of the pressure, and the liquid leakage phenomenon may occur, so that the high temperature and high pressure gas needs to be discharged in time to ensure the balance between the inside of the aromatherapy bottle 10 and the external gas. The body 110 is further provided with a pressure release channel 112, the pressure release channel 112 is utilized to balance the air pressure inside the aromatherapy bottle 10 with the air pressure outside, the high-temperature and high-pressure air generated inside the aromatherapy bottle 10 flows into the pressure release channel 112, and then is discharged to the outside through the pressure release channel 112 when the air pressure of the pressure release channel exceeds the preset air pressure, and it is required to be noted here that the pressure release channel 112 can realize pressure balance, one end of the pressure release channel 112 is directly communicated with the bottle 200, the other end is communicated with the outside, or one end of the pressure release channel 112 is directly communicated with the air guide channel 111 so as to be communicated with the bottle 200 through the air guide channel 111, and the other end is communicated with the outside.
