Abstract

The invention discloses a humidifying tank. The humidifying tank comprises a humidifying tank main body, and an air inlet pipe and an air outlet which are arranged on the humidifying tank main body, the air inlet pipe comprises an air inlet end and an air outlet end, the lower portion of the air inlet end of the air inlet pipe is higher than the lower portion of the air outlet end in the horizontal direction, the length of the air inlet pipe is greater than or equal to half of the length of the humidifying tank main body in the air inlet pipe direction or is greater than the shortest length from the air outlet to the wall of the air inlet pipe, a liquid in the humidifying tank evaporates and is condensed in the air inlet pipe and can flow back into the humidifying tank through the inclinedarrangement of the air inlet pipe, when the liquid in the humidifying tank tilts, the liquid cannot enter the air inlet pipe, when the humidifying tank is turned over, the length from the air outletto the wall where the air inlet pipe is located is larger than that of the air inlet pipe, the humidifying tank is turned over to a certain angle, water flow can flow out of the air outlet and cannotenter the air inlet pipe, it is also guaranteed that the liquid cannot flow into a respiratory therapy equipment host, so that 360-degree overflow prevention is achieved. The through cavity is adopted, so that airflow impedance can be greatly reduced, and airflow output efficiency is improved.

Description

technical field [0001] The invention relates to a humidification tank used for inhalable gas supply equipment, in particular to a humidification tank with anti-reflux function, which belongs to the field of medical equipment. Background technique [0002] The equipment used for continuous positive airway pressure therapy usually includes a blower, and the air outlet of the blower is connected to a mask through a breathing tube to interact with the patient's air. Usually, the warmed and humidified air is more comfortable and acceptable to the patient. Therefore, currently existing ventilation therapy equipment is provided with a humidifier device. [0003] Typically, the blower and humidifier units are separate components connected by a hose. The humidifier device is generally installed between the air outlet of the blower and the patient interface, and usually includes a humidification tank and a heating device, and the humidification tank is provided with an air inlet con...
