Abstract

The present disclosure discloses a humidification device, and a humidifier and a ventilator to overcome deficiencies in the prior art such as the heating efficiency of a ventilator being relatively low when the amount of water in a humidification device is adequate. The humidification device comprises a heating area and a liquid conveying device conveying a liquid to the heating area, the liquid conveying device comprising a liquid inlet pipeline, the liquid inlet pipeline extending into the heating area and extending to a bottom of the heating area, and a reserved interval being provided between an outlet of the liquid inlet pipeline and the bottom of the heating area. According to the embodiments of the present disclosure it is ensured that the heating efficiency may be increased and the heating time may be reduced in the case of continuous use.

wherein the reserved interval is greater than 5 mm and smaller than 30 mm,
a seal element located in the bottom of the heating area blocks off the outlet of the liquid inlet pipeline under a buoyancy action of the liquid in the heating area,
the seal element has a base part and a seal part arranged on the base part,
a sum of a height of the base part and a height of the seal part, is greater than a distance from the outlet of the liquid inlet pipeline to a bottom surface of the heating area, and
the seal part is always positioned in the outlet of the liquid inlet pipeline.

2. The humidification device according to claim 1 , wherein the liquid conveying device further comprises an air outlet pipeline, an inlet of the liquid inlet pipeline is lower than an outlet of the air outlet pipeline, an outlet of the liquid inlet pipeline is lower than an inlet of the air outlet pipeline, and both the outlet of the liquid inlet pipeline and the inlet of the air outlet pipeline extend into the heating area.

3. The humidification device according to claim 2 , wherein the outlet of the air outlet pipeline is disposed in a liquid storage area, when the liquid level of the liquid storage area is not lower than the outlet of the air outlet pipeline n the liquid storage area, the liquid in the liquid storage area enters the heating area via the liquid inlet pipeline and the air outlet pipeline, the air in the heating area enters the liquid storage area via the air outlet pipeline; when the liquid level of the heating area rises above the inlet of the air outlet pipeline in the heating area, the liquid in the liquid storage area stops flowing into the heating area via the liquid inlet pipeline.

4. The humidification device according to claim 1 , further comprising a liquid storage area connected to the liquid conveying device, wherein the outlet of the liquid inlet pipeline is connected to the liquid storage area.

5. A humidifier, comprising a heating element and a humidification device, wherein the humidification device comprises a heating area and a liquid conveying device conveying liquid to the heating area, the liquid conveying device comprising a liquid inlet pipeline, the liquid inlet pipeline extending into the heating area and extending to a bottom of the heating area, and a reserved interval being provided between an outlet of the liquid inlet pipeline and the bottom of the heating area; and wherein the heating element heats the liquid in the heating area of the humidification device;
wherein the reserved interval is greater than 5 mm and smaller than 30 mm,
a seal element located in the bottom of the heating area blocks off the outlet of the liquid inlet pipeline under a buoyancy action of the liquid in the heating area,
the seal element has a base part and a seal part arranged on the base part,
a sum of a height of the base part and a height of the seal part, is greater than a distance from the outlet of the liquid inlet pipeline to a bottom surface of the heating area, and
the seal part is always positioned in the outlet of the liquid inlet pipeline.

6. The humidifier according to claim 5 , wherein the liquid conveying device further comprises an air outlet pipeline, an inlet of the liquid inlet pipeline is lower than an outlet of the air outlet pipeline, an outlet of the liquid inlet pipeline is lower than an inlet of the air outlet pipeline, and both the outlet of the liquid inlet pipeline and the inlet of the air outlet pipeline extend into the heating area.

7. The humidifier according to claim 5 , further comprising a liquid storage area connected to the liquid conveying device, wherein the outlet of the liquid inlet pipeline is connected to the liquid storage area.

8. A ventilator, comprising a main machine and a humidifier, wherein the humidifier comprises a heating element and a humidification device, the humidification device comprises a heating area and a liquid conveying device conveying liquid to the heating area, the liquid conveying device comprising a liquid inlet pipeline, the liquid inlet pipeline extending into the heating area and extending to a bottom of the heating area, a reserved interval being provided between an outlet of the liquid inlet pipeline and the bottom of the heating area, and the heating element heats the liquid in the heating area of the humidification device; and wherein the main machine being connected to an air inlet of the heating area, and a pipeline that is capable of being connected to a human body being connected to an air outlet of the heating area;
wherein the reserved interval is greater than 5 mm and smaller than 30 mm,
a seal element located in the bottom of the heating area blocks off the outlet of the liquid inlet pipeline under a buoyancy action of the liquid in the heating area,
the seal element has a base part and a seal part arranged on the base part,
a sum of a height of the base part and a height of the seal part, is greater than a distance from the outlet of the liquid inlet pipeline to a bottom surface of the heating area, and
the seal part is always positioned in the outlet of the liquid inlet pipeline.
