Provided is a steam physiotherapy device, containing: a water tank (10), a boiler body (20) having a steam outlet (20B), a liquid inlet channel (30) which communicates the water tank (10) with the boiler body (20), a water valve mechanism (40) for controlling the liquid inlet channel (30) to be opened and closed, and a heating mechanism (50) arranged on the boiler body (20). The heating mechanism (50) is used for heating water flowing into the boiler body (20) to generate steam. The liquid inlet channel (30) contains: a first flow channel (30A), a water inlet section thereof being in communication with the water tank (10)； a second flow channel (30B), a water outlet section thereof being in communication with the boiler body (20)； and a third flow channel (30C), which communicates a water outlet section of the first flow channel (30A) with a water inlet section of the second flow channel (30B). The first flow channel (30A) extends in a transverse direction, and the second flow channel (30B) extends in the transverse direction； the height of the second flow channel (30B) in the steam physiotherapy device is greater than the height of the first flow channel (30A) in the steam physiotherapy device； and the third flow channel (30C) communicates the first flow channel (30A) with the second flow channel (30B). The device facilitates the alleviation of the problem of water back-flow.L'invention concerne un dispositif de physiothérapie à vapeur, contenant : un réservoir d'eau (10), un corps de chaudière (20) ayant une sortie de vapeur (20B), un canal d'entrée de liquide (30) qui fait communiquer le réservoir d'eau (10) avec le corps de chaudière (20), un mécanisme de vanne d'eau (40) pour contrôler le canal d'entrée de liquide (30) devant être ouvert et fermé, et un mécanisme de chauffage (50) disposé sur le corps de chaudière (20). Le mécanisme de chauffage (50) est utilisé pour chauffer l'eau s'écoulant dans le corps de chaudière (20) pour générer de la vapeur. Le canal d
