Wherein the gas is usually air or oxygen, and the humidifying liquid 4 is usually purified water.
Through the technical scheme, the humidifying tank is provided with the air flow channel used for communicating the air inlet 2 and the air outlet 3 in the tank body 1, air can be guided to enter from the air inlet 2 through the air flow channel and flow out from the air outlet 3 after flowing through the chamber in a mode of being close to the humidifying liquid 4, and because the humidifying liquid 4 is heated to generate damp and hot air in the humidifying process, the introduced air can be fully mixed and contacted with the damp and hot air when flowing close to the humidifying liquid 4, meanwhile, the circulating line of the air in the tank body 1 is prolonged, the residence time of the air in the tank body 1 is prolonged, the humidifying efficiency of the air is improved, and the comfort of patients when the patients are in is effectively improved.
In order to facilitate the gas entering the tank 1, the gas inlet 2 is provided with a one-way valve 14, and as an alternative embodiment, the one-way valve 14 adopts a sloping plate structure and is rotatably arranged on the tank 1. When the gas is introduced, the inclined plate structure is pushed to be opened under the action of the air flow so as to facilitate the gas to enter the tank body 1, and after the gas is introduced, the inclined plate structure freely falls under the action of gravity so as to close the air inlet 2, so that the gas in the tank body 1 can be prevented from flowing out.
Wherein, for the convenience of setting and simultaneously bringing convenience of gas and hot humid gas into contact, preferably, the cavity is arranged at the lower part of the tank body 1.
The air flow channel can be arranged in the tank body 1 in any suitable way, so long as the introduced gas is ensured to flow through the cavity in a manner of being close to the humidifying liquid 4, and the introduced gas and the hot humid gas are fully mixed and contacted, so that the humidifying efficiency of the gas is improved. As an embodiment of the invention, the gas inlet 2 is arranged at the side of the tank 1 above the chamber, the gas flow channel comprises a first channel 7 from the gas inlet 2 to the chamber, and the first channel 7 comprises a first baffle 5 arranged at the gas inlet 2 for guiding the gas to flow downwards.
Here, when the first baffle 5 is set, a space needs to be reserved between the bottom of the first baffle 5 and the liquid level of the humidifying liquid 4 in the chamber, so that gas can enter the chamber from the first channel 7 at a certain flow rate, and the gas required by a human body is ensured.
Further, since the wet and hot gas content of the liquid surface area of the wetting liquid 4 is higher as the wetting liquid 4 is evaporated, that is, the wetting efficiency is higher as the air flow is closer to the liquid surface. To ensure that the incoming gas is in sufficient contact with the hot humid gas to increase the humidifying efficiency of the gas, the gas flow channel comprises a second channel 8 guiding the gas entering the chamber to flow over and close to the humidifying liquid 4, the second channel 8 comprising a second baffle 6 arranged over the bottom wall of the chamber.
As shown in fig. 2, the first baffle 5 is disposed at one side of the chamber, one end of the second baffle 6 is in contact with the first baffle 5, and the other end of the second baffle 6 is disposed at the other side of the chamber with a space between the end and the inner wall of the tank 1 to guide the gas to flow upward out of the chamber. Of course, the present invention may also define the flow channels with any flow direction by changing the positions of the baffles or adding the number of baffles, so long as it is ensured that the gas, after being introduced from the gas inlet 2, can flow through the chamber in a manner of being close to the humidifying liquid 4, and finally flows out from the gas outlet 3.
The gas outlet 3 is provided at the top of the tank 1 in consideration of the flow characteristics of the gas while extending the flow path of the gas in the tank 1.
After the inlet gas is fully contacted with the hot and humid gas in the cavity, the inlet gas flows out of the cavity upwards from the space and enters the position above the second baffle plate 6, so that the tank body 1 is provided with an airflow cavity above the second baffle plate 6. In order to ensure that the introduced gas and the hot and humid gas are fully mixed again in the airflow cavity, preferably, the gas outlet 3 and the interval are respectively positioned at two sides of the airflow cavity, and a blocking piece 15 is arranged in the tank 1 corresponding to the gas outlet 3 so that the gas can fully flow in the airflow cavity. Preferably, the blocking member 15 is inclined so as to better guide the gas, specifically, the inclined surface of the blocking member 15 faces the space and is far away from the gas outlet 3, when the gas reaches the gas outlet 3, the gas collides with the blocking member 15 and is rebounded so as to obtain sufficient flow in the gas flow cavity, and finally, the humidified gas with high humidification rate is fully mixed and finally flows out from the gas outlet 3.
After the gas is introduced from the gas inlet 2, the gas sequentially enters the gas flow cavity through the first channel 7, the second channel 8 and the interval, and finally flows out from the gas outlet 3. The setting of above-mentioned air current passageway can make full use of the inner space of jar body 1, the length of setting of extension air current passageway in jar body 1 for the time of stay is longer in jar body 1 of letting in gas, thereby let letting in gas and damp and hot gas obtain intensive mixing, effectively improved whole humidifying efficiency. It will be appreciated that other adaptation of the present invention to the airflow path in order to extend the airflow path within the tank 1 is within the scope of the present invention.
As one embodiment of the present invention, the first baffle 5 is vertically disposed inside the tank 1, the second baffle 6 is horizontally disposed inside the tank 1, and one end of the second baffle 6 contacts the first baffle 5, so that the inlet gas can completely flow into the second channel 8 from the first channel 7 to contact the hot and humid gas. Of course, the first baffle 5 and the second baffle 6 may also be disposed obliquely, which is not limited herein. In order to guide the gas entering from the gas inlet 2 so that the gas smoothly enters the first passage 7, the tip of the first baffle 5 is provided with an arc portion 16, and the arc portion 16 is convexly provided in a direction away from the gas inlet 2.
In order to facilitate the positioning and fixing of the second baffle 6, the second baffle 6 is provided with a supporting member 9 for supporting the second baffle 6. In this embodiment, the supporting member 9 is disposed at the bottom of the second baffle 6, and the distance between the second baffle 6 and the bottom wall of the chamber may be adjusted by adjusting the setting height of the second baffle 6, that is, the height or the diameter of the second channel 8 may further achieve flow control of the gas, so in use, the setting height of the second baffle 6 may be adjusted or the supporting member 9 may be set to be telescopic according to the requirement of the gas flow. Of course, the supporting member 9 may be disposed at any suitable position according to actual needs, so long as it functions to support and fix the second baffle 6, for example, may be disposed on an inner wall of the tank 1, and fix the second baffle 6 by clamping or the like.
In the use process, the humidifying liquid 4 in the cavity needs to be continuously heated and evaporated to generate damp and hot gas to humidify the introduced gas, so that the humidifying liquid 4 in the cavity needs to be always maintained at a certain liquid level to ensure the humidifying effect, the humidifying liquid 4 in the cavity is prevented from being completely evaporated and cannot continuously generate the damp and hot gas, and the aim of gas humidification cannot be achieved.
Based on the consideration of the above problem, in order to facilitate the entering of the humidification liquid 4 and maintain the constant volume of the humidification liquid 4 in the chamber, the tank 1 is provided with a liquid inlet 10 for introducing the humidification liquid, the humidification tank comprises a float 12 and a float limiting piece 11 for limiting the floating range of the float 12, a water inlet hole communicated with the liquid inlet 10 is penetrated and arranged in the float limiting piece 11, the float 12 is positioned on the liquid surface of the humidification liquid and floats up and down along with the liquid level to open or block the water inlet hole, and in order to avoid the obstruction of the second baffle 6 to the floating of the float 12, the second baffle 6 is provided with a through hole for penetrating the float 12, and the float limiting piece 11 can also penetrate through the through hole to be arranged so as to guide the floating of the float 12.

Before use, the liquid level of the humidifying liquid 4 in the chamber is set to be maintained, and at the height, the floater 12 contacts with the floater limiting piece 11 so as to seal the water inlet, namely, the humidifying liquid 4 does not need to be introduced into the chamber.
When the liquid level of the humidifying liquid 4 is lower than the set height due to evaporation of the humidifying liquid 4, the float 12 descends along with the liquid level, the water inlet of the float limiting piece 11 is opened, therefore, the humidifying liquid 4 flows into the cavity along the liquid inlet 10 and the water inlet in sequence, the float 12 gradually ascends along with the liquid level during continuous feeding of the humidifying liquid 4 until the liquid level reaches the set height, and the float 12 contacts with the float limiting piece 11 again to seal the water inlet, so that liquid feeding is stopped. Through this design, can guarantee in the cavity humidifying liquid 4 remains in fixed height all the time to guarantee going on smoothly of gas humidifying process.
Further, since the float 12 may pass through the second passage 8 during its floating, the bottom of the second baffle 6 is provided with an arcuate partition 13 partially surrounding the float 12 in order to prevent the float movement from being affected by the flow of gas in the second passage 8. Thereby, the gas in the second passage 8 will pass along both sides and the bottom of the arc-shaped partition 13, without impeding the flow of gas and without affecting the float 12.
In order to further improve the humidifying effect, under the premise of not changing the size of the equipment, the tank body 1 is preferably of a square structure, so that the heated area of the humidifying liquid 4 at the bottom of the tank body 1 can be increased, the uniform heating of gas is ensured, and meanwhile, the length of a gas path is increased, so that the gas humidifying effect is better.
The invention also provides a ventilation treatment device which comprises a gas generating device and the humidification tank. The ventilation treatment device adopts the humidification tank, so that all advantages of the humidification tank are achieved. The gas generated by the gas generating device enters the humidifying tank through the gas inlet 2 to finally complete the humidification. The ventilation treatment device can increase the residence time of the gas in the tank body 1, improve the humidification efficiency of the gas, and further effectively improve the comfort of patients when the patients are in.
