In a first aspect, an embodiment of the present invention provides a tank structure, fig. 1 shows an exploded structure schematic view of a tank structure provided in an embodiment of the present application, fig. 2 shows an external structure schematic view of a tank structure provided in an embodiment of the present application, and fig. 3 shows a cross-sectional structure schematic view of a tank structure provided in an embodiment of the present application along A-A direction in fig. 2, as shown in fig. 1 to 3, the tank structure includes:

the box 1, the box 1 includes the cavity, and the cavity is constructed to hold humidification liquid for the humidification of the gas that gets into in the cavity, is equipped with inlet channel 12 and outlet channel 11 on the box 1.

Gas humidifying member 2, the gas humidifying member 2 is provided in the chamber, the gas humidifying member 2 includes a humidifying passage 21, and gas that has entered the chamber from the gas inlet passage 12 enters the humidifying passage 21 via the gas humidifying member 2, and the humidifying passage 21 communicates with the gas outlet passage 11.

As can be seen from the above embodiments, in the embodiment of the present invention, since the case 1 includes the chamber configured to hold the humidifying liquid for humidifying the gas entering the chamber, the case 1 is provided with the gas inlet passage 12 and the gas outlet passage 11, the gas humidifying member 2 is provided in the chamber, the gas humidifying member 2 includes the humidifying passage 21, the gas entering the chamber from the gas inlet passage 12 enters the humidifying passage 21 via the gas humidifying member 2, and the humidifying passage 21 and the gas outlet passage 11 communicate, so that the gas entering the chamber from the gas inlet passage 12 is brought into contact with not only the humidifying liquid in the chamber but also the gas humidifying member 2, so that the gas can enter the humidifying passage 21 after being further humidified by the gas humidifying member 2, and finally enter the gas outlet passage 11 via the humidifying passage 21. Like this, the gas that gets into the cavity from inlet channel 12 can get into the gas outlet channel after further humidification through gaseous humidification spare 2 further humidification for the gas that flows out from the gas outlet channel 11 gets into further humidification, can strengthen the humidification ability of water tank structure, and then promotes user's use experience.

In the above embodiment, the case 1 may be a square case structure, a cylindrical case structure, or other case structures, which is not limited in the embodiment of the present invention. The inlet channel 12 and the outlet channel 11 may be tubular structures provided on the casing 1.

In some embodiments, the gas flow direction in the gas inlet channel 12 and the gas flow direction in the gas outlet channel 11 intersect, that is, the axis of the gas inlet channel 12 and the axis of the gas outlet channel 11 intersect, so that the heating element may not be provided at the bottom of the case 1.

The gas humidifying member 2 may be a hydrophilic material such as a water-absorbent resin, a water-absorbent fiber, or a sponge, which is not limited in the embodiment of the present invention, and the gas humidifying member 2 may be fixed in the chamber by a connection manner such as a clamping connection, a plugging connection, or an adhesive connection. In this way, the heated gas entering the chamber can be humidified by the gas humidifying member 2. The middle part of the gas humidifying member 2 may be provided with a humidifying channel 21, and the humidifying channel 21 is communicated with the gas outlet channel 11, so that the gas humidified by the gas humidifying member 2 may enter the gas outlet channel 11 through the humidifying channel 21, and the gas flowing out of the gas outlet channel 11 may be further humidified.

In some embodiments, the gas delivered into the chamber through the inlet passage 12 is a heated gas at a preset temperature threshold.

It should be noted that, the preset temperature threshold in the above embodiment is a threshold at which the maximum temperature value and the minimum temperature value of the temperature range of the gas required for the user to breathe are located, for example, 30 ℃ to 34 ℃. In this way, since the gas transferred into the chamber through the gas inlet passage 12 is the heated gas at the preset temperature threshold, when the heated gas entering the chamber from the gas inlet passage 12 contacts the humidifying liquid in the chamber (including the humidifying liquid stored at the bottom of the chamber absorbed on the gas humidifying member 2 and the humidifying liquid remaining after the bottom of the chamber is absorbed by the gas humidifying member 2), the humidifying effect of the gas can be improved when the gas having a temperature contacts the liquid, and therefore the heated gas is the humidified gas having a certain temperature outputted from the chamber into the gas outlet passage 11. Since the heating gas humidifying process consumes a part of heat of the heating gas, the temperature of the heated gas after being humidified is reduced compared with the temperature input through the air inlet channel 12. In addition, the gas humidifying piece 2 is arranged in the chamber, so that the gas entering the chamber contacts with the humidifying liquid absorbed by the gas humidifying piece 2 in the process of entering the humidifying channel 21 besides contacting with the liquid stored at the bottom of the chamber, the total contact area of the heated gas in the chamber and the humidifying liquid is increased, and the humidifying effect of the heated gas is improved.

The following details of the structure of the water tank and the related assembly modes provided in the embodiments of the present invention are specifically described below:

in some possible embodiments, the chamber comprises a first inner cavity 13 and a second inner cavity 14 which are separated, the air inlet channel 12 is communicated with the first inner cavity 13, an air inlet 15 which is communicated with the first inner cavity 13 and the second inner cavity 14 is formed between the first inner cavity 13 and the second inner cavity 14, the humidifying liquid is stored in the second inner cavity 14, and the gas humidifying piece 2 is arranged in the second inner cavity 14.

It should be noted that, the case 1 may be an integral structure, in which the first inner cavity 13 and the second inner cavity 14 are separated by an internal baffle, or the case 1 may be a split structure, in which the first inner cavity 13 and the second inner cavity 14 are separated by other structures. The first inner chamber 13 and the second inner chamber 14 being blocked off may be understood as not communicating with each other between the first inner chamber 13 and the second inner chamber 14 except for the communicating structure (the air inlet 15 in the embodiment of the present invention). In this way, the heated gas introduced into the second inner chamber 14 is humidified by the gas humidifying member 2 and then introduced into the humidifying passage 21, and then introduced into the gas outlet passage 11 through the humidifying passage 21. Because the air outlet channel 11 is communicated with the humidifying channel 21 in the second inner cavity 14 and is not communicated with the first inner cavity 13, the air entering the first inner cavity 13 from the air inlet channel 12 cannot directly flow out from the air outlet channel 11, but firstly enters the second inner cavity 14 through the air inlet 15, fully contacts with humidifying liquid in the second inner cavity 14 and then flows out from the air outlet channel 11, and therefore, the humidifying effect of the water tank structure is improved through the arrangement of the two separated chambers. Meanwhile, through the partition between the first inner cavity 13 and the second inner cavity 14, the gas is humidified in the second inner cavity 14 only, so that the space for gas flow humidification is reduced, and a certain heat preservation effect is achieved on the gas entering the water tank cavity, particularly the heated gas.

In some embodiments, as shown in fig. 3 and 6, the tank structure further comprises a baffle 3; the baffle 3 divides the chamber into a first inner cavity 13 and a second inner cavity 14, and an air inlet 15 is formed in the baffle 3.

It should be noted that, the baffle 3 may be a square plate, a circular plate, or a plate structure with other shapes, and the specific shape of the baffle 3 is determined according to the inner cavity of the water tank structure, which is not limited in the embodiment of the present invention. The baffle 3 can be fixed in the inner cavity of the box body 1 in a connection mode such as clamping, welding or bonding, and further can partition the box body 1 into a first inner cavity 13 and a second inner cavity 14. If the case 1 is of a split structure, the baffle 3 may also serve as a transition connection member between the two split structures of the case 1. In this way, the gas inlet 15 may be provided on the baffle 3, so that the heated gas entering the first interior chamber 13 may pass from the gas inlet 15 into the second interior chamber 14. It should be further noted that, the air inlet 15 is a through hole or a through slot structure formed on the baffle 3, the air inlet 15 may be a round hole structure, a square slot structure, or another through slot structure, and the air inlet area of the air inlet 15 is determined according to the air flow resistance in the box 1, which is not limited in the embodiment of the present invention.

In the above embodiment, the chamber is partitioned into the first inner cavity 13 and the second inner cavity 14 by the baffle 3, on one hand, the gas humidifying piece 2 arranged at the bottom of the baffle 3 can be limited and fixed, the gas humidifying piece 2 is prevented from moving along the extending direction of the central axis of the chamber, and on the other hand, the space of gas flow humidification is reduced by the baffle 3, so that the cooling and humidifying effects are further improved.

For the structure of the case 1, the case 1 may be an integral structure or a split structure, which is not limited in the embodiment of the present invention.

In the case where the case 1 is of a split structure, the case 1 includes an upper cover 16 and a base 17; the upper cover 16 is connected to the base 17, the baffle 3 is connected between the upper cover 16 and the base 17, the cavity between the upper cover 16 and the baffle 3 constitutes the first inner cavity 13, and the cavity between the base 17 and the baffle 3 constitutes the second inner cavity 14.

It should be noted that, the upper cover 16 may be a bottom-open housing structure, and the base 17 may be a top-open housing structure. Under the influence of the baffle 3, the cavity between the upper cover 16 and the baffle 3 constitutes a first cavity 13, and the cavity between the base 17 and the baffle 3 constitutes a second cavity 14. In this way, the upper cover 16 and the base 17 are two independent parts, so that the gas humidifying piece 2 is convenient to install in the second inner cavity 14 between the base 17 and the baffle 3, and meanwhile, the upper cover 16 and the base 17 are two independent parts, so that the subsequent maintenance and replacement of the box body 1 can be convenient.

Further, for the split structure of the case 1, in some embodiments, the air outlet channel 11 is formed at the top of the upper cover 16, the air inlet channel 12 is formed at the side of the upper cover 16, the baffle 3 is provided with a switching channel 31, and the humidifying channel 21 is communicated with the air outlet channel 11 through the switching channel 31.

In addition, the baffle 3 is provided with at least one structure of a switching cylinder, a switching pipeline or other communication pipelines, so that the humidifying gas flowing out of the humidifying channel 21 can be directly introduced into the air outlet channel 11 through the switching channel 31, and the heat loss of the humidifying gas in the path flowing into the air outlet channel 11 is reduced.

With respect to the configuration of the inlet channels, in some embodiments, the inlet channel 12 includes a first channel 121 and a second channel 122, the second channel 122 communicates with the outlet channel 11, and the first channel 121 communicates with the first interior cavity 13.

It should be noted that, regarding the structures of the first channel 121 and the second channel 122, the first channel 121 and the second channel 122 may be two channels independent of each other, that is, the first channel 121 and the second channel 122 are two parallel pipeline structures. Alternatively, the second passage 122 may be provided in the first passage 121, that is, the first passage 121 is wrapped around the periphery of the second passage 122, in other words, in the second passage 122, in the gap between the first passage 121 and the second passage 122, the heating gas may be passed through, that is, the heating gas may be made to enter the case 1 with two passages. In this way, since the second channel 122 is communicated with the air outlet channel 11, the heated air entering the second channel 122 can directly flow into the air outlet channel 11, so that temperature compensation is performed on the slightly cooled humidified air flowing out of the humidifying channel in the air outlet channel 11, so that the humidified air conveyed to the user side by the air outlet channel 11 is at a comfortable temperature, and the use effect of the user is improved. In this way, the heated gas entering from the first channel 121 may be humidified by the gas humidifying member 2, cooled and humidified, and then mixed with the heated gas entering from the second channel 122, so that the gas exiting from the gas outlet channel 11 is at a suitable therapeutic temperature. Since the first channel 121 is used for inputting the pre-humidified gas into the box body, which is a key to realize the box body humidifying function, and the second channel 122 is used for performing temperature compensation on the gas in the gas outlet channel 11, which is a secondary function, and the amount of the high-temperature gas for temperature compensation is not required to be more, the cross-sectional area of the first channel 121 is generally larger than that of the second channel 122.

Further, in some embodiments, the second channel 122 communicates on one side of the through channel 31 such that the second channel 122 communicates with the outlet channel 11 through the through channel 31. In this way, the heated gas flowing in from the second channel 122 can be introduced into the gas outlet channel 11 through the switching channel 31, and the heated gas in the gas outlet channel 11 is "neutralized" with the gas cooled and humidified by the gas humidifying member 2, so that the temperature and humidity of the gas in the gas outlet channel 11 can be easily controlled, and the condition that the temperature of the gas directly passing through the heated gas in the gas outlet channel 11 is low and is not suitable for human body is avoided. In some embodiments, an opening may be provided in the transit passage 31 corresponding to the end of the second passage 122, such that the end of the second passage 122 is aligned with the opening in the transit passage 31, such that heated gas within the second passage 122 that meets a preset temperature threshold enters the transit passage 31 through the opening.

Optionally, a pipeline connector 32 is disposed on one side of the switching channel 31, and the second channel 122 is communicated with the air outlet channel 11 through the pipeline connector 32.

In the above embodiment, the second channel 122 is communicated with the air outlet channel 11 through the pipeline interface 32, so that the heated air flowing from the second channel 122 can be directly introduced into the air outlet channel 11 through the switching channel 31 in a butt joint mode, so that the communication between the second channel 122 and the switching channel 31 is relatively simple. Illustratively, taking the transfer channel 31 as a transfer cylinder, the transfer cylinder and the pipeline interface 32 together form a "three-way structure", and the specific three channels are two ends of the transfer cylinder and an end of the pipeline interface 32 far from the transfer cylinder. In this way, the heating gas in the second channel 122 can be introduced into the switching cylinder through the pipeline interface 32, and then flows into the air outlet channel 11 through the switching cylinder, and the heating gas in the first channel 121 can be blocked through the switching cylinder, so that the heating gas in the first channel 121 can only circulate through the air inlet 15 between the first inner cavity 13 and the second inner cavity 14. The switching cylinder body can be of a square cylinder body structure, a round cylinder body structure or other cylinder body structures. The pipeline interface 32 and the second channel 122 are preferably communicated in a port butt joint mode, and a tiny gap is reserved between the end part of the pipeline interface 32 of the department and the end part of the second channel 122, so that interference of installation positions generated between the air inlet channel 12 arranged on the upper cover and the switching channel 31 arranged on the baffle 3 when the water tank structure is installed is avoided. In addition, the included angle between the axis of the air inlet channel 12 and the plane of the baffle 3 is an acute angle, that is, the air inlet channel 12 is obliquely arranged, so that the liquid solidified by cooling can be prevented from flowing into the transfer channel 31 from the air inlet channel 12.

Further, in the case that the end of the second channel 122 or the end of the pipe joint 32 is provided with a semi-enclosed shielding structure 1221 protruding from the end, and the end of the second channel 122 is aligned with the end of the pipe joint 32 when the second channel 122 is connected to the pipe joint 32, the shielding structure 1221 partially shields the periphery of the aligned position. As shown in fig. 5, the shielding structure 1221 extends beyond the end of the second channel 122 and partially shields the gap in the aligned position around the top of the aligned position when the end of the second channel 122 and the end of the line interface 32 are aligned to reduce gas leakage from the gap in the aligned position when the second channel 122 and the line interface 32 are aligned.

To ensure tightness of the gas flow, in some embodiments, the bottom end of the gas outlet channel 11 and the top end of the transfer channel 31 are in sealing communication by a sealing ring 4.

In this embodiment, the seal ring 4 may include a first seal portion and a second seal portion, the first seal portion and the second seal portion being connected. Taking the transfer channel 31 as a cylindrical barrel for example, the first sealing part and the second sealing part are both in circular ring structures, and the diameter of the first sealing part is smaller than that of the second sealing part. In this way, during connection, the first sealing part can be embedded in the cavity of the transit passage 31, so that the first sealing part is in interference fit with the transit passage 31, so that the second sealing part is embedded with the air outlet passage 11, and so that the second sealing part is in interference fit with the air outlet passage 11. In this way, the sealing ring 4 can enable the air outlet channel 11 and the switching channel 31 to be in a sealing state, so that air leakage between the air outlet channel 11 and the switching channel 31 is avoided. The material of the sealing ring 4 may be a material with a certain sealing effect, such as nitrile rubber, polyurethane rubber, polypropylene rubber, silicone rubber, fluororubber, butyl rubber, ethylene propylene rubber, neoprene rubber, etc., which is not limited in the embodiment of the present invention.

Further, the air inlet 15 and the first channel 121 are located on two sides of the central axis of the first inner cavity 13, respectively.

By arranging the gas inlet 15 and the first passage 121 on both sides of the central axis of the first inner chamber 13, that is, by arranging the gas inlet 15 and the first passage 121 on both sides of the central axis of the first inner chamber 13 in opposite directions, the heated gas entering the first inner chamber 13 through the first passage 121 is prevented from flowing backward, that is, the heated gas entering the first inner chamber 13 enters the second inner chamber 14 through the gas inlet 15 after a certain distance of travel.

Optionally, the cross-sectional area of the air inlet 15 in the first plane is greater than or equal to the cross-sectional area of the first channel 121 in the second plane, wherein the first plane and the second plane are planes perpendicular to each other, and the first plane is a plane perpendicular to the central axis of the first inner cavity 13. Therefore, when the cross-sectional area of the first plane of the air inlet 15 is greater than or equal to the cross-sectional area of the first channel 121 in the second plane, the air resistance of the first channel 121 entering the first inner cavity 13 is ensured to be consistent with the air resistance of the first channel entering the second inner cavity 14 through the air inlet 15, and the normal circulation of the heating gas is ensured.

For the connection between the upper cover 16 and the baffle 3, in some embodiments, the baffle 3 is further connected with a positioning ring 5, and the positioning ring 5 is wound around the periphery of the baffle 3; at least part of the positioning ring is made of flexible materials, such as silica gel materials, so that the baffle 3 is positioned and fixed in the box body 1 through the positioning ring 5.
