Humidifying device with water level monitoring function and water level monitoring method and equipment

Abstract

The invention discloses a humidifying device with a water level monitoring function and a water level monitoring method and equipment. A U-shaped communicating pipeline is arranged in a water box of the humidifying device, the U-shaped communicating pipeline is inversely arranged in the water box of the humidifying device and comprises a first pipeline, a connecting part and a second pipeline, a port of the first pipeline is communicated with the interior of the water box of the humidifying device, a port of the second pipeline is a pressure collecting port, and the pressure collecting port is in a sealed state when not used for pressure collection. According to the invention, the water box of the humidifying device and the first pipeline form an U-shaped connecting pipe U1, the first pipeline and the second pipeline form an U-shaped connecting pipe U2, the water level height in the water box is calculated according to the water level height relation, accurate water level alarm can be achieved by monitoring the water level in the water box of the humidifying device, and dry burning and overflow due to the too high water level are prevented; and the use time after water adding can be accurately calculated, so that the user can add water according to the use time, and the work of accompanying personnel is relieved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a humidification device with a water level monitoring function, a water level monitoring method and equipment. Background technique [0002] Existing humidification devices do not have accurate water level monitoring functions, but only have anti-dry function and high and low water level monitoring functions. Among them, the anti-dry function is to detect the temperature of the heating plate through the temperature sensor at the bottom of the heating plate to achieve the anti-dry function. According to the principle of heat transfer, when there is water, the temperature of the heating plate is transferred to the humidified water in the water box, and the water temperature will not exceed 100 ℃, so the maximum temperature of the heating plate of the humidification device is about 100 ℃. When the water in the humidification water box is used up, the continuous h...
