The wormwood smoke purifier 5 of the present embodiment is equivalent to a negative pressure machine to extract wormwood smoke and purify wormwood smoke; the present embodiment realizes the upward and downward transportation of wormwood smoke and wormwood heat, and reduces the influence of wormwood smoke on the smoke exhaust device.
[0034] As a further improved embodiment, the third smoke exhaust pipe 24 is tilted downward, with an inclination angle of no more than 30°, and the downward-facing end is installed on the fourth smoke exhaust pipe 25. In this embodiment, by tilting the air outlet end of the third smoke exhaust pipe 24 downward, it is convenient to introduce the moxa smoke in the third smoke exhaust pipe 24 into the fourth smoke exhaust pipe 25, and also reduce the adhesion of the moxa smoke to the third smoke exhaust pipe 24, wherein the lowest point of the third smoke exhaust pipe 24 should be higher than the height of three-quarters of the moxibustion box 2. The height to prevent the moxibustion material inside the moxibustion box 2 from moving upward is greater than the lowest point of the third smoke exhaust pipe 24, thereby preventing large particles of moxa smoke from entering the third smoke exhaust pipe 24, thereby increasing the service life of the third smoke exhaust pipe 24.
[0035] As a further improved embodiment, the fourth smoke exhaust pipe 25 is a rectangular box structure, and the two third smoke exhaust pipes 24 are respectively close to the top corners of the fourth smoke exhaust pipe 25; wherein the fourth smoke exhaust pipe 25 is fixed to the end of the long side direction of the moxibustion box 2, and the heat in the moxibustion box 2 is isolated to prevent the tail end of the bed shell 1 from being too high in temperature; The first smoke exhaust pipe 21 is used to output the moxa smoke and moxa heat from the fourth smoke exhaust pipe 25, and the first smoke exhaust pipe 21 is close to the bottom end of the fourth smoke exhaust pipe 25, wherein the lower end of the fourth smoke exhaust pipe 25 is close to the middle of the moxibustion box 2; The fourth smoke exhaust pipe 25 and the first smoke exhaust pipe 21 are fixed to each other, wherein the fourth smoke exhaust pipe 25 is provided with a second cavity 250, and the second cavity 250 is used to transport moxa smoke and moxa heat; The fifth smoke exhaust pipe 4 is a corrugated pipe, which extends downward by bending and is connected to the moxa smoke purifier 5; The moxa smoke purifier 5 includes a negative pressure smoke extractor and a three-way catalytic converter. The moxa smoke purifier 5 is used to extract the moxa smoke and moxa heat in the first smoke exhaust pipe 21 and perform smoke destruction on the extracted moxa smoke; The moxa smoke purifier 5 is arranged along one end of the long side of the moxibustion box 2 and is located outside the moxibustion box 2, wherein the lower end of the moxa smoke purifier 5 is fixed on the support plate 14, and the support plate 14 and the bed shell 1 are fixed to each other; The height of the moxa smoke purifier 5 is lower than that of the fourth smoke exhaust pipe 25, so the fifth smoke exhaust pipe 4 is extended downward from a high place and connected to the moxa smoke purifier 5, thereby reducing the moxa smoke adhering to the fourth smoke exhaust pipe 25, thereby preventing the extraction pressure of the third smoke exhaust pipe 24 from being affected. In this embodiment, the entire smoke exhaust pipeline flows from high to low, reducing the degree of settlement of moxa smoke in the first smoke exhaust pipe 21, the third smoke exhaust pipe 24, the fourth smoke exhaust pipe 25 and the fifth smoke exhaust pipe 4, and also reducing the impact on the heat exhaust and smoke exhaust efficiency of the third smoke exhaust pipe 24.
