Humidifier and humidifying box capable of achieving automatic water adding for same

Abstract

The invention discloses a humidifying box capable of achieving automatic water adding. The upper portion of an inner cavity of a box body is partitioned into a water storage cavity through a first partition plate. The space below the first partition plate is partitioned into a humidifying cavity and a transition cavity through a second partition plate in a left-right mode. An assembling hole is formed in the first partition plate. A water level hole is formed in the second partition plate. An ejector rod penetrates through the assembling hole. A sealing gasket is arranged below the ejector rod. An elastic device compressing the sealing gasket into the assembling hole is arranged on the sealing gasket. The ejector rod is pressed downwards so that the sealing gasket and the assembling hole can be separated, and humidifying fluid in the water storage cavity flows into the transition cavity; an upper cover and the box body are in sealed connection, the portion, above the humidifying fluid, in the water storage cavity is a closed space, under the atmospheric effect, only a part of the humidifying fluid in the transition cavity flows out, the liquid level in the humidifying cavity can only reach the upper edge of the water level hole, when the liquid level descends, the humidifying fluid is supplemented to the humidifying cavity through the water level hole, and automatic water supplementing is achieved. The invention further provides a humidifier comprising the humidifying box. The humidifier can achieve the same technical effects.

Description

Technical field [0001] The present invention relates to the technical field of medical devices, and further relates to a humidification box capable of automatically adding water. In addition, this application also relates to a humidifier with the above humidification box. Background technique [0002] The output of the ventilator is dry gas. Patients who breathe in for a long time are prone to side effects, such as dry nasal cavity, tongue headache, and even nose bleeding. Therefore, the ventilator is usually equipped with a heater to increase the humidity of the inhaled lung gas to prevent the above problems. , So that patients feel more comfortable and relaxed breathing. [0003] The humidifier contains a humidification box for placing the humidification liquid, heating the humidification box to evaporate the humidification liquid, and the dry gas can increase the humidity after passing through the humidification box. As the ventilator continues to supply oxygen, the humidifica...

AI Technical Summary

Problems solved by technology

The traditional humidification box structure cannot realize automatic addition of humidification fluid, and can only be added manually. To achieve automatic addition, liquid level detection devices and switch controls need to be installed. The overall structure is complex, which is not conducive to large-scale promotion and use.
