Description

Structure improvement of automatic water injection and humidification chamber

This creation relates to a humidification chamber, especially an automatic water injection humidification chamber structure improvement, a float (Float) is provided in the humidification chamber, and the float is suspended from the humidification chamber cover, so that the float The bottom will not touch the heated plate of the humidification chamber; during the humidification process, the humidification chamber can be replenished with liquid, and the float can rise and fall with the water level. When the float blocks the water inlet of the humidification chamber (Water inlet) ), the humidification chamber can stop replenishing liquid to control the water level of the humidification chamber.

The first known technology is US Patent No. US20160199614, which mainly discloses a float holding device for a humidification chamber. A primary float 116 is connected to a coupling arm 118. The main The float (116) moves a push rod 124 via the coupling arm (118) to actuate a primary valve 112; the push rod (124) includes a pivotally connected to the connecting arm (118) ) The lower end portion (128) and the upper end portion (126), the upper end portion (126) includes a valve body (130), the valve body (130) can directly or indirectly engage a first valve seat (132), to Close the main valve (112) and prevent water from entering the humidification chamber (100) through the main valve (112); the valve body (130) can also be detached from the first valve seat (132) to open the main valve (112) and allow water to enter the humidification chamber (100); one end of a supply pipe (150) is connected to a water inlet (108), and the other end of the supply pipe (150) is connected to an adapter for The supply pipe (150) is connected to a water source, and the adapter may be in the form of a spunlace (152), which may serve as a holding device for the main float (116). The assembly of the first known technology is not easy and the cost is high, so there is still a need for improvement of the first known technology.

The second known technology, such as the US Patent No. US7722016, mainly discloses a humidification chamber with a float having a seal that can move into and out of the valve seat, so that when the humidification A water inlet is sealed when the water level of the chamber 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 stand-off ribs 94 to prevent the lower end of the float from contacting A heat conduction plate. When the water level of the humidification chamber is too low, the spacer rib (94) of the float may still contact the heat conduction plate. When the water inlet no longer replenished water into the humidification chamber (for example: a water storage container connected to the water inlet is no longer water), the spacer rib (94) of the float may still contact the heat conduction plate. Therefore, there is still a need for improvement in the second conventional technology.

The purpose of this creation is to provide an improved structure of an automatic water injection and humidification chamber. The automatic water injection and humidification chamber has a float. The float is a hollow container including an extension, a plurality of hooks, a plurality of recesses, and a seal; the The extension part is provided at the center of the float, the plurality of hooks are provided at the top end of the extension part, the plurality of concave parts surround the extension part, and the seal can be fixed to the top end of the extension part; wherein the float can The hook is suspended in a chamber space of the humidification chamber, the concave At least two complex air passages are formed in the chamber space, and the outer side of the float forms at least two annular air passages in the chamber space.

The effect of this creation gain (1) is that the extension of the float is directly coupled to the extension tube of the cover, and the extension is directly suspended from the extension tube, that is, the extension tube of the cover can be used as the The holding device of the float makes the bottom of the float form a distance from the heated plate; therefore, the assembly of the original creation is easy and the cost can be reduced.

The effect of this creative gain (2) is that when a gas enters the chamber space, the complex air passage can increase the residence time of the gas, and the annular air passage can guide the moisture in the chamber space, so that the gas and The moisture is thoroughly mixed.

The effect (3) of this creative gain lies in that the plurality of concave portions are symmetrically arranged on the float, and the plurality of airway partitions are symmetrically arranged inside the cover; thereby, the assembly of the float and the cover is protected against Foolproof; because the assembly of the float and the cover has a foolproof effect, the air inlet of the cover and the air outlet of the cover also have a foolproof effect, that is, the air inlet and The air outlet can be used interchangeably, and the user does not need to distinguish the air inlet from the air outlet.
