Description

Humidification tank Technical Field The invention relates to a humidifying tank for inhalable gas supply equipment, in particular to a humidifying tank with an anti-backflow function, and belongs to the field of medical appliances. Background Devices for continuous positive airway pressure therapy typically include a blower with its outlet connected to a mask via a breathing circuit for air exchange with the patient. Typically, the heated humidified air is more comfortable and acceptable to the patient. Thus, currently existing ventilation therapy devices are provided with humidifier devices. Typically, the blower and humidifier device are separate components connected by a hose. The humidifier device is generally arranged between the air outlet of the blower and the patient interface, and generally comprises a humidifying tank and a heating device, wherein the humidifying tank is provided with an air inlet and is connected with the air outlet of the blower, the air outlet is connected with the user interface, a certain amount of water is added in the humidifying tank, and air entering the humidifying tank from the blower enters the patient interface after being subjected to humidity through the heating system of the heating device and the contact of the air with the water. Some ventilation therapy devices are configured to couple a blower to a humidifier device for portability. Air flows out of the blower air outlet, enters the humidifying tank inlet of the humidifier device, flows out of the humidifier device outlet after being humidified in the humidifying tank, enters the breathing pipeline and finally reaches the patient interface (e.g. mask end). This design presents a potential problem in terms of how the humidifier apparatus can be tilted relative to its normal orientation so that water within the apparatus does not flow into the blower, cause damage to the blower, and even cause damage to the apparatus, which is a further problem to be addressed. In the prior art, two methods for solving the problem that water in a humidification tank overflows to flow back to a blower in structural design are generally adopted, one method is to add an independent chamber to isolate direct paths between water and an air outlet of the blower as shown in fig. 1, and the other method is to add a baffle and lower a water level line to enable the water level to be far lower than the air outlet of the blower as shown in fig. 2. From the heating and humidifying system, a passive enhanced humidifying system is added, namely, the heating and humidifying system comprises a heat-moisture exchange material, a heating plate, an insulating plate and the like.
