Humidifying tank

Abstract

The invention relates to the technical field of medical instruments, in particular to a humidifying tank. The humidifying tank comprises a humidifying tank main body and a cover body, and the cover body can cover the humidifying tank main body and define a tank cavity. The humidifying tank is characterized by further comprising a partition plate arranged in the tank cavity, the partition plate divides the tank cavity into an air inlet cavity and a humidifying cavity, the cover body is provided with an air inlet and an air outlet, the air inlet communicates with the air inlet cavity, the air outlet communicates with the humidifying cavity, the partition plate is provided with a water storage tank in the air inlet cavity, a drainage face is arranged in the water storage tank, the partition plate is further provided with a communicating hole for communicating between the air inlet cavity and the humidifying cavity, the drainage face is used for guiding liquid in the water storage tank to flow into the communicating hole, and the air inlet is higher than the drainage face. According to the humidifying tank, liquid in the humidifying tank can be effectively prevented from flowing back outwards through the air inlet, and when the humidifying tank is turned over, even if the liquid enters the air inlet cavity through the communicating hole, the liquid can flow back to the humidifying cavity in time under the guidance of the water storage tank, so that the liquid is prevented from entering the air inlet.

Description

technical field [0001] The invention relates to the technical field of humidification devices, in particular to a humidification tank. Background technique [0002] In order to increase lung ventilation, improve respiratory function, and reduce respiratory consumption, a continuous positive airway pressure ventilation therapy device is usually used, which can continuously deliver pressurized gas to the user end through a fan to complete the communication with the user. Breath interaction. However, it is usually difficult for users to accept the pressurized cold air, and the drier air will cause certain damage to the mucous membranes of the human body. Heating and humidifying make the user more comfortable and acceptable. [0003] The humidifier device usually includes a humidification tank and a heating device. The humidification tank usually has an air inlet and an air outlet. The wind directly enters the humidification tank through the air inlet, and after being humidif...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the inlet of the humidification tank may be directly connected to the fan and other electronic devices in the ventilation treatment equipment due to the consideration of the volume of the ventilation treatment equipment. If the ventilation treatment equipment is tilted carelessly, it will easily lead to humidification. The liquid in the tank flows into the main body of the equipment where the fan and other electronic components are located through the air inlet, which will cause damage to the electronic components and equipment

[0005] Therefore, how to better prevent the liquid in the humidification tank from flowing back through the air inlet to cause equipment damage is a technical problem urgently needed to be solved by those skilled in the art.
