Description

Humidification chamber with suspended float

The invention relates to a humidification chamber, in particular a humidification chamber with a water level control valve. The water level control valve is provided with a float. During the humidification process, the humidification chamber will consume The liquid in the humidification chamber; when the humidification chamber is replenished with liquid, the float rises as the water level increases, and the water level control valve can block the water inlet of the humidification chamber to control the humidification Water level in the room.

Conventional technology, such as U.S. Publication No. US7722016, mainly discloses a humidifying chamber having a float, which has seals that can move into and out of the valve seat, so that when the The water inlet of the wet chamber is sealed when the water level exceeds the first level, and the water inlet is opened when the water level of the humidification chamber is lower than the first level. The float has spacer ribs to prevent the lower end of the float from contacting a heat conduction plate. When the water level in the humidification chamber is too low, the spacer ribs of the float may still contact the heat conduction plate. When the water inlet no longer replenishes water into the humidification chamber (for example, a water storage container connected to the water inlet is no longer water), the spacer ribs of the float may still contact the heat conduction plate. Therefore, there is still a need for improvement in this conventional technology.

An object of the present invention is to provide a humidification chamber with a suspended float including a cover, a water level control valve, and a heated plate. The cover has a water inlet, an air inlet, and an outlet. Air port; the water level control valve has a limiting element, a float and a sealing piece; wherein the sealing piece is arranged at the top of the float, the heating plate seals the cover to form a cavity space; when the liquid passes through the water inlet When the water inlet of the chamber enters the chamber space, the float rises with the increase of the water level; when the sealing sheet contacts the water inlet of the water inlet, the sealing sheet can block the water inlet of the water inlet; when the When the water level in the chamber space drops, the limiting element can prevent the bottom of the float from contacting the heated plate.

The effect (1) of the gain of the present invention is that when the cavity space is insufficient to replenish liquid, the float can be suspended from the limiting element, so that the bottom of the float forms a distance from the heated plate; when the cavity space is completely In the absence of liquid, the bottom of the float will still not contact the heated plate.

The effect (2) of the gain of the present invention is that the top of the float has at least one pressure relief hole, and the sealing sheet is attached to the top of the float and closes the pressure relief hole to prevent the liquid from penetrating into the float; when the heat receiving plate When the liquid is heated, the expansion pressure of the float is released from the pressure relief hole.
