The humidifier humidifies oxygen by passing it into water to increase the humidity of the oxygen, making it smoother and more comfortable for users to breathe oxygen. However, when oxygen is passed into water, bubbles will be generated, which will produce bubbling sounds, increase the noise of the entire machine, and affect the user experience.

[0048] Embodiment 1

[0049] like Figure 1 , Figure 2 As shown, the humidification device includes a shell component 10 and a wet curtain component 20; the shell component 10 includes an isolated water adding area 110 and a humidification area 120, and the water adding area 110 surrounds the humidification area 120; the wet curtain component 20 is arranged in the humidification area 120, and the wet curtain component 20 is connected with the water adding area 110, and the wet curtain component 20 can absorb water in the water adding area 110; wherein, the shell component 10 is provided with an air inlet 160 and an air outlet 170 connected with the humidification area, so that the wet curtain component 20 can humidify the gas to be humidified flowing into the humidification area 120.

[0050] By setting up the isolated water adding area 110 and the humidifying area 120, a structural basis is provided for humidifying the gas to be humidified. The water adding area 110 is used to store water for moistening the wet curtain assembly 20, and the humidifying area 120 is used for humidifying the gas to be humidified, thereby realizing functional zoning and avoiding the generation of bubbling sound when the gas passes through the water adding area 110; the wet curtain assembly 20 absorbs the water in the water adding area 110 to make the wet curtain assembly 20 rich in moisture. When the humidified gas passes through the wet curtain assembly, the moisture in the wet curtain assembly can be taken out to complete the humidification of the gas to be humidified, thereby increasing the humidity of the gas to be humidified and fully eliminating the bubbling sound, thereby effectively reducing noise and improving user experience.

[0051] It should be noted that the gas to be humidified includes but is not limited to oxygen.

[0052] It should also be noted that the wet curtain assembly 20 has water absorption and emission capabilities. The water absorption enables the wet curtain assembly 20 to absorb moisture and enrich itself with moisture, and the emission capability enables the wet curtain assembly 20 to emit moisture, thereby providing a basis for humidifying the gas to be humidified.

[0053] Embodiment 2

[0054] like Figure 1 , Figure 2 As shown, the humidification device includes a shell component 10 and a wet curtain component 20; the shell component 10 includes an isolated water adding area 110 and a humidification area 120, and the water adding area 110 surrounds the humidification area 120; the wet curtain component 20 is arranged in the humidification area 120, and the wet curtain component 20 is connected with the water adding area 110, and the wet curtain component 20 can absorb water in the water adding area 110; wherein, the shell component 10 is provided with an air inlet 160 and an air outlet 170 connected with the humidification area, so that the wet curtain component 20 can humidify the gas to be humidified flowing into the humidification area 120.

[0055] By setting up the isolated water adding area 110 and the humidifying area 120, a structural basis is provided for humidifying the gas to be humidified. The water adding area 110 is used to store water for moistening the wet curtain assembly 20, and the humidifying area 120 is used for humidifying the gas to be humidified, thereby realizing functional zoning and avoiding the generation of bubbling sound when the gas passes through the water adding area 110; the wet curtain assembly 20 absorbs the water in the water adding area 110 to make the wet curtain assembly 20 rich in moisture. When the humidified gas passes through the wet curtain assembly, the moisture in the wet curtain assembly can be taken out to complete the humidification of the gas to be humidified, thereby increasing the humidity of the gas to be humidified and fully eliminating the bubbling sound, thereby effectively reducing noise and improving user experience.

[0056] It should be noted that the gas to be humidified includes but is not limited to oxygen.

[0057] It should also be noted that the wet curtain assembly 20 has water absorption and emission capabilities. The water absorption enables the wet curtain assembly 20 to absorb moisture and enrich itself with moisture, and the emission capability enables the wet curtain assembly 20 to emit moisture, thereby providing a basis for humidifying the gas to be humidified.

[0058] like Figure 3 , Figure 4 As shown, in some embodiments, the wet curtain assembly 20 includes a first support portion 210, a second support portion 220 and a wet curtain portion 230; the second support portion 220 is arranged opposite to the first support portion 210; both ends of the wet curtain portion 230 are arranged on the first support portion 210 and the second support portion 220; wherein, the second support portion 220 is provided with a water inlet channel connected to the water adding area 110, and one end of the wet curtain portion 230 is located in the water inlet channel.

[0059] The first support part 210 and the second support part 220 are provided to support the wet curtain part 230, so as to ensure that the wet curtain part 230 is in an expanded state, and the wet curtain part 230 is prevented from collapsing, resulting in a reduction in the surface area of ​​the wet curtain part 230, so that the gas to be humidified can be fully in contact with the wet curtain part 230, and the humidification effect of the gas to be humidified can be ensured. By providing a water inlet channel and locating one end of the wet curtain part 230 in the water inlet channel, the wet curtain part 230 can be in contact with the water flowing into the water inlet channel, providing moisture for the wet curtain part 230, so that the wet curtain part 230 can absorb moisture and maintain a wet state. In addition, the wet curtain assembly 20 will not absorb moisture after the moisture is completely absorbed, so there is no need to frequently add water or replace the wet curtain assembly 20, which improves the user experience.

[0060] It should be noted that the first support portion 210 and the second support portion 220 are not water-absorbent, while the wet curtain portion 230 has water-absorbent and water-dispersing capabilities, and is corrosion-resistant and has a filtering effect on impurities such as dust in the humidified gas. For example, the wet curtain portion 230 is glass fiber or coated corrugated paper.

[0061] It should also be noted that one end of the water inlet channel is connected to the water inlet 2203, and the other end is blocked to prevent water from the water adding area 110 from flowing into the humidification area 120 through the water inlet channel.

[0062] It should also be noted that the length and depth of the water inlet channel are set as needed, for example, according to the water absorption strength of the wet curtain portion 230; the length and depth of the water inlet channel cannot be too large, otherwise it will lead to too much water in the water inlet channel, and there is a risk of water overflowing into the humidification area 120, resulting in bubbling sound when the humidified gas flows in; of course, the length and depth of the water inlet channel cannot be too small, otherwise it will lead to less water in the water inlet channel, affecting the wetting speed of the wet curtain portion 230.

[0063] It should also be noted that the two ends of the wet curtain portion 230 are respectively fixed to the first support portion 210 and the second support portion 220. For example, the two ends of the wet curtain portion 230 can be respectively fixed to the first support portion 210 and the second support portion 220 by bonding.

[0064] like Figure 3 , Figure 4 As shown, in some embodiments, the second support portion 220 includes an annular support segment 2201 and a plurality of wetting segments 2202; a plurality of water inlet holes are provided on the outer wall of the annular support segment 2201, and the plurality of water inlet holes are arranged circumferentially around the annular support segment 2201; a plurality of wetting segments 2202 are provided on the inner wall of the annular support segment 2201, and the plurality of wetting segments 2202 are arranged circumferentially around the annular support segment 2201 and correspond one-to-one to the plurality of water inlet holes respectively; wherein a water inlet channel is provided on the wetting segment 2202, and the water inlet channel is connected to the water inlet hole.

[0065] By setting a plurality of wetting sections 2202, the structure of the second support portion 220 is matched with the structure of the wet curtain portion 230, which can not only provide sufficient support for the wet curtain portion 230, but also increase the wetting speed of the wet curtain portion 230; by setting a water inlet hole connected to the water adding area 110, the water in the water adding area 110 can flow into the water inlet hole and fill the water inlet hole, thereby continuously supplying water to the water inlet channel and making the wet curtain portion 230 rich in moisture.

[0066] It should be noted that the wetting section 2202 and the annular supporting section 2201 are connected by means including but not limited to integral molding.

[0067] It should also be noted that the annular support segment 2201 and the first support portion 210 are both in contact with the inner wall of the partition 1503, reducing the gap between the annular support segment 2201 and the partition 1503, and the gap between the first support portion 210 and the partition 1503, thereby preventing the humidified gas from directly flowing out without being humidified, affecting the user's experience.

[0068] They are all in the shape of a circular ring, and the circular support segment 2201 and the first support portion 210 include but are not limited to a circular ring.

[0069] It should also be noted that the number of the infiltration sections 2202 is set as required, for example, Figure 3 As shown, the second support portion 220 includes six wetting sections 2202, which are arranged at equal intervals around the annular support section 2201. The annular support section 2201 is provided with six water inlets 2203, and the six wetting sections 2202 correspond to the six water inlets 2203 one by one.

[0070] like Figure 3 , Figure 4As shown, in some embodiments, the wet curtain portion 230 includes an annular curtain 2301 and a plurality of partition curtains 2302; one end of the annular curtain 2301 is located in the water inlet channel; a plurality of partition curtains 2302 are arranged circumferentially around the annular curtain 2301, and the plurality of partition curtains 2302 extend along the radial direction of the first wet curtain and intersect in the annular curtain 2301, and a portion of the partition curtains 2302 is located outside the annular curtain 2301; wherein the plurality of partition curtains 2302 correspond one-to-one to the plurality of wetting sections 2202, respectively, one end of the partition curtain 2302 is arranged on the first support portion, and the other end is arranged on the corresponding wetting section 2202 and is located in the water inlet channel.

[0071] By providing an annular curtain 2301 and a plurality of partition curtains 2302 arranged at circumferential intervals, the surface area of ​​the wet curtain portion 230 is increased, so that the contact area between the wet curtain portion 230 and the gas to be humidified is increased, thereby ensuring the humidification effect on the gas to be humidified; at the same time, the annular curtain 2301 and the partition curtain 2302 form a plurality of isolated humidification channels, which divert the inflowing gas to be humidified to reduce the flow rate of the gas to be humidified and extend the humidification time of the gas to be humidified in the wet curtain portion 230, thereby ensuring sufficient contact between the gas to be humidified and the wet curtain portion 230, thereby further improving the humidification effect of the gas to be humidified.

[0072] It should be noted that the infiltration section 2202 is respectively provided with a groove body for inserting the annular curtain 2301 and the separating curtain 2302, and the groove body is connected with the water inlet channel, so that one end of the annular curtain 2301 and the separating curtain 2302 is located in the water inlet channel, and the annular curtain 2301 and the separating curtain 2302 can continuously absorb moisture.

[0073] like Figure 1 , Figure 2 As shown, in some embodiments, the shell assembly 10 includes a shell 130, a cover plate 140 and a partition 150; the cover plate 140 is detachably disposed on the shell 130; the partition 150 is disposed in the shell 130 to separate the shell 130 into a water adding area 110 and a humidification area 120; wherein the air inlet 160 is disposed on one end of the shell 130 away from the cover plate 140, and the air outlet 170 is disposed on one end of the cover plate 140 away from the shell 130.

[0074] The cover plate 140 and the shell 130 are detachably connected, so that the cover plate 140 and the shell 130 are a split structure, which is convenient for adding water and replacing the wet curtain part 230; by arranging the air inlet 160 on the shell 130 and the air outlet 170 on the cover plate 140, the gas to be humidified is wetted from bottom to top by the wet curtain, and the wet curtain part 230 absorbs moisture from bottom to top, which can effectively promote the absorption and release of water by the wet curtain part 230, and improve the humidity of the gas to be humidified when the whole machine just starts to work.

[0075] It should be noted that the cover plate 140 includes but is not limited to being detachably connected to the housing 130 by means of threaded connection.

[0076] like Figure 5 , Figure 6 As shown, in some embodiments, the partition 150 includes a bottom plate 1501 and a partition 1503; the bottom plate 1501 is arranged in the shell 130, and an air inlet hole 1502 is arranged on the bottom plate 1501, and the air inlet hole 1502 is respectively connected with the air inlet 160 and the wet curtain part 230; the partition 1503 is arranged on the bottom plate 1501, and the partition 1503, the bottom plate 1501 and the shell 130 together form a water adding area 110, and the partition 1503 and the bottom plate 1501 together form a humidification area 120; wherein, a plurality of water outlet holes 1505 are arranged on the partition 1503, and the plurality of water outlet holes 1505 correspond to the plurality of water inlet holes one by one, respectively, and the water outlet holes 1505 are connected with the corresponding water inlet holes.

[0077] By setting a bottom plate 1501 and an air inlet 1502 on the bottom plate 1501, the gas to be humidified is buffered before humidification to obtain a relatively smooth airflow, thereby avoiding the impact on the wet curtain part 230 when the humidified gas enters the humidification area 120, reducing noise, and extending the service life of the wet curtain assembly 20.

[0078] It should be noted that there are multiple air inlet holes 1502 , and the multiple air inlet holes 1502 can be arranged in a circular array around the bottom plate 1501 .

[0079] It should also be noted that the bottom plate 1501 and the shell 130 are connected by, but not limited to, integral molding, and the partition 1503 and the bottom plate 1501 are connected by, but not limited to, integral molding.

[0080] It should also be noted that the water inlet hole is arranged on one end of the partition 1503 close to the bottom plate 1501.

[0081] It should also be noted that a sealing member is provided at one end of the water outlet 1505 close to the water inlet, thereby improving the sealing performance and preventing water from leaking into the humidification area 120 .

[0084] By setting up the isolated water adding area 110 and the humidifying area 120, a structural basis is provided for humidifying the gas to be humidified. The water adding area 110 is used to store water for moistening the wet curtain assembly 20, and the humidifying area 120 is used for humidifying the gas to be humidified, thereby realizing functional zoning and avoiding the generation of bubbling sound when the gas passes through the water adding area 110; the wet curtain assembly 20 absorbs the water in the water adding area 110 to make the wet curtain assembly 20 rich in moisture. When the humidified gas passes through the wet curtain assembly, the moisture in the wet curtain assembly can be taken out to complete the humidification of the gas to be humidified, thereby increasing the humidity of the gas to be humidified and fully eliminating the bubbling sound, thereby effectively reducing noise and improving user experience.

[0096] It should also be noted that the annular support segment 2201 and the first support portion 210 are both in contact with the inner wall of the partition 1503, reducing the gap between the annular support segment 2201 and the partition 1503, and the gap between the first support portion 210 and the partition 1503, thereby preventing the humidified gas from directly flowing out without being humidified, affecting the user's experience.

[0097] They are all in the shape of a circular ring, and the circular support segment 2201 and the first support portion 210 include but are not limited to a circular ring.

[0176] By setting the card slot 1504 and the buckle 2101 in cooperation, the detachable connection between the wet curtain assembly 20 and the partition 1503 is realized, which is simple and convenient; at the same time, the card slot 1504 and the buckle 2101 structure can play a guiding and limiting role, so that the water inlet hole and the water outlet hole 1505 are aligned, avoiding water from flowing into the humidification area 120, causing bubbling sound when the humidified gas flows into the humidification area 120.

[0177] It should be noted that the card slot 1504 is located on one end of the partition 1503 close to the cover plate 140, and the specific number of the card slots 1504 is set as needed. For example, the partition 1503 is provided with a plurality of card slots 1504, and the plurality of card slots 1504 are arranged around the partition 1503 in a circumferential direction.
