Description

Humidification chamber with float

The present invention relates to a humidification chamber, in particular to a humidification chamber having a water level control valve, the water level control valve is provided with a float (Float); during humidification, the humidification chamber consumes a liquid in the humidification chamber; when the humidification chamber replenishes the liquid, the float rises as the water level increases, and the water level control valve blocks the water inlet of the humidification chamber to control the humidification The water level in the room.

A commonly disclosed technique is a humidifying chamber having a float having a seal movable into and out of the valve seat, such that the plus The water level of the wet chamber is sealed to a water inlet when the water level exceeds the first level, and the water inlet is opened when the water level of the humid chamber is lower than the first level, the float having spaced ribs to prevent the lower end of the float from contacting a heat conducting plate. When the water level of the humidification chamber is too low, the spacer ribs of the float may still contact the heat transfer plate. When the water inlet no longer replenishes water into the humidification chamber (for example, a water storage container connected to the water inlet has no water), the spacer ribs of the float may still contact the heat transfer plate. Therefore, there is still an improved need for this prior art.

The purpose of the present invention is to provide a humidification chamber having a float including a cover, a limiting member, a float and a heated plate; the cover has a water inlet, an air inlet and a water outlet a gas port, the inner side of the water inlet has an extension tube, the inner wall surface of the extension tube has a plurality of guiding ribs; the limiting element has a perforation and an inner flange, the inner flange has at least one notch; the extension of the float The portion has at least one hook, the top end of the extending portion is provided with a sealing sheet; the heat receiving plate seals the cover body to form a chamber space; wherein the extending portion can pass through the through hole, and the hook can pass through the notch The float can be rotated at an angle such that the hook is located inside the inner flange; the limiting member can be fixed to the extension tube such that the plurality of guiding ribs of the extension tube can separate the hook from the notch.

The effect of the creation gain (1) is that when the chamber space is insufficient to replenish the liquid, the float can be suspended from the limiting member such that the bottom of the float forms a distance from the heated plate; when the chamber is completely spaced When there is no liquid, the bottom of the float still does not touch the heated plate.

The effect of the creation gain (2) is that the top end of the float has at least one pressure relief hole, the sealing sheet is attached to the top end 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 by the pressure relief hole.

The effect of the creation gain (3) is that the inner flange of the limiting element has at least one notch; the notch helps the liquid to enter the chamber space when the water inlet of the water inlet receives liquid.

Referring to FIG. 1 to FIG. 10, in a preferred embodiment, the humidifying chamber of the present invention comprises a cover 10, a limiting member 20, a float 30, a sealing sheet 40 and a heated plate 50; The cover body 10 has a water inlet port 11, an air inlet port 12 and an air outlet port 13. The inner side of the water inlet port 11 has an extension tube 111. The inner wall surface of the extension tube 111 has a plurality of guiding ribs 113. 20 has a through hole 21 and an inner flange 23, the inner flange 23 has at least one notch 26; the float 30 has an extension 31, the side surface 311 of the extending portion 31 has at least one hook 33; the sealing sheet 40 can be disposed at the top end 312 of the extending portion 31; the heat receiving plate 50 is located below the cover body 10, and the heat receiving plate 50 seals the The cover body 10 is formed to form a chamber space 51; wherein the extension portion 31 can pass through the through hole 21, the hook 33 can pass through the notch 26 (as shown in FIGS. 3 and 9), and the float 30 can be rotated. The angle is such that the hook 33 is located inside the inner flange 23 (as shown in FIGS. 9 and 10); the limiting member 20 can be fixed to the extension tube 111 such that the plurality of guiding ribs 113 of the extension tube 111 The hook 33 and the notch 26 can be separated (as shown in FIG. 4); when the chamber space 51 is free of any liquid, the hook 33 stops at the inner flange 23, and the float 30 can be suspended from the The limiting member 20 is such that the bottom portion 35 of the float 30 forms a distance D with the heat receiving plate 50. When the water inlet hole 110 of the water inlet 11 receives a liquid, the water level of the chamber space 51 rises, so that the float 30 As the water level increases, when the sealing sheet 40 contacts the water inlet hole 110 of the water inlet 11, the sealing sheet 40 can block the water inlet 11 a water hole 110 (shown in FIGS. 7 to 8); the heat receiving plate 50 can heat the liquid in the chamber space 51 to provide moisture; when the air inlet 12 inputs a gas to the chamber space 51, the The gas is mixed with the moisture into a breathing airflow having an appropriate humidity, and the breathing airflow can be output from the air outlet 13.

The safety of the preferred embodiment of the present invention is as follows: the water inlet 12 can be connected to a water storage container (not shown) to supplement the liquid in the chamber space 51; when the liquid of the water storage container is insufficient, The water level of the chamber space 51 will be greatly reduced, however, the hook 33 can be stopped at the inner flange 23, so that the float 30 can be suspended from the limiting member 20 (as shown in Figures 5 to 6); The chamber space 51 is completely free of liquid, and the bottom 35 of the float 30 still does not contact the heated plate 50.

The combination of the float 30 and the sealing sheet 40 is as follows: the float 30 has an upper cover 301 and a container 302. The extending portion 31 is located on the upper cover 301. A fixing post 42 of the sealing sheet 40 can be fixed to the fixing member 42. A fixing hole 32 of the extending portion 31 is disposed such that the sealing piece 40 can be disposed at the top end 312 of the extending portion 31.

The pressure relief hole 314 is closed to prevent the liquid from penetrating into the float 30; when the heat receiving plate 50 heats the liquid, the expansion pressure of the float 30 is released by the pressure release hole 314. Therefore, the sealing sheet 40 can prevent the liquid from penetrating into the float 30, and the sealing sheet 40 can also release the expansion pressure of the float 30.

The water inlet mode of the chamber space 51 is as follows: the side surface 311 of the extension portion 31 has a pair of hooks 33, and the inner flange 23 forms a gap g with the extension portion 31; when the water inlet port 11 enters When the water hole 110 inputs the liquid, the liquid enters the chamber space 51 from the gap g and the notch 26.

The guiding manner of the float 30 is as follows: the limiting member 20 is fixed to the extension tube 111 (for example, a tight fit), and the plurality of guiding ribs 113 can assist the center line C1 of the extending portion 31 to be aligned with the water inlet. The water inlet hole 110 of the 11 and guides the movement of the float 30.

The manner in which the heat receiving plate 50 and the cover 10 are sealed is as follows: the cover 10 has an annular edge 15 , and the edge 55 of the heated plate 50 is sealed to the annular edge 15 , and the edge 55 of the heated plate 50 A seal ring 60 is disposed intermediate the annular rim 15; wherein the seal ring 60 can enclose the annular rim 15.
