Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
The embodiment of the utility model provides an at first provides a stock solution device 10. In addition to the conventional liquid storage function, the liquid storage device 10 of the present embodiment further has a filtering function, and can separate soluble substances in the gas to play a role of purifying the gas.
Fig. 1 is a schematic block diagram of a liquid storage device 10 according to an embodiment of the present invention. The reservoir 10 may generally include a tank 100 and an air resistance mechanism 200.
Wherein the interior of the tank 100 defines a liquid storage space. The reservoir space is used to hold a liquid, such as water, or other solution. The kind of the liquid may be set according to the dissolution property of the gas to be filtered and the dissolution property of the impurities contained in the gas to be filtered, as long as the impurities contained in the gas to be filtered can be dissolved in the liquid and the gas to be filtered itself is hardly dissolved in the liquid.
For example, when the impurity contained in the gas to be filtered is an acidic aqueous solution or an alkaline aqueous solution, and the gas to be filtered is oxygen, the liquid contained in the liquid storage space may be water. The following will take this as an example and describe in detail various embodiments of the present invention. Those skilled in the art should fully appreciate that the present invention can be extended and changed for other application scenarios without departing from the scope of the present invention.
The air-blocking mechanism 200 is disposed in the liquid storage space and separates the liquid storage space into an air-filtering area 112 and an air-non-filtering area 114 with blocked air passages. Wherein the air filtering area 112 is used for allowing air from the outside of the box 100 to flow therethrough to realize filtering. The non-filtered air region 114 is a liquid storage space outside the filtered air region 112. In this embodiment, the air-filtering region 112 is a sub-space in the liquid storage space, and the air-non-filtering region 114 can be another sub-space in the liquid storage space.
The air-filtering area 112 and the non-air-filtering area 114, in which the air-blocking mechanism 200 separates the liquid storage space into air paths, means that the air-blocking mechanism 200 blocks the air flow path between the air-filtering area 112 and the non-air-filtering area 114, so that the air flowing through the air-filtering area 112 cannot enter the non-air-filtering area 114. For example, the gas filtering area 112 may be opened with a gas inlet 122 and a gas outlet 124 communicating with the external environment of the box 100, so that the gas in the external environment of the box 100 can be introduced into the gas filtering area 112 through the gas inlet 122, and the gas filtered by the gas filtering area 112 can flow out of the box 100 through the gas outlet 124.
With the above structure, the air blocking mechanism 200 is disposed in the box 100 of the liquid storage device 10, and the air blocking mechanism 200 is used to separate the liquid storage space into the air filtering area 112 and the non-air filtering area 114, which are blocked by air paths, so that the function of cleaning air only in the air filtering area 112 can be realized. Since the air-filtering area 112 is only a sub-space of the liquid storage space and is blocked from the air path between other areas of the liquid storage space, the air from the outside of the tank 100 can only flow in the air-filtering area 112, and cannot freely diffuse to the non-air-filtering area 114, which results in the inability to discharge quickly, so the liquid storage device 10 of the embodiment has a high purge gas release rate.
In some alternative embodiments, the unfiltered gas section 114 is configured to receive liquid from outside the enclosure 100. For example, the non-filtered gas region 114 may be provided with a liquid inlet 126 to allow external liquid to flow into the non-filtered gas region 114 through the liquid inlet 126. In this embodiment, the gas-unfiltered region 114 can further include a liquid outlet to allow the liquid therein to flow out of the gas-unfiltered region 114 through the liquid outlet and into an environment of use, such as the oxygen treatment device 20 described below.
When the air-blocking mechanism 200 blocks the air path between the air-filtering area 112 and the air-non-filtering area 114, the air filtering process performed in the air-filtering area 112 and the liquid injection process or the liquid discharge process performed in the air-non-filtering area 114 can be performed simultaneously, and do not interfere with each other.
The air lock mechanism 200 blocks a portion of the fluid path between the filtered air region 112 and the unfiltered air region 114 such that the filtered air region 112 and the unfiltered air region 114 remain in fluid path communication in the event of a fluid path blockage. That is, the air lock mechanism 200 only blocks the air path between the filtered air region 112 and the unfiltered air region 114, but does not block the fluid path between the filtered air region 112 and the unfiltered air region 114.
When the non-filtered air region 114 is used for receiving liquid from the outside of the tank 100, and the air blocking mechanism 200 blocks a part of the liquid path between the filtered air region 112 and the non-filtered air region 114, so that the filtered air region 112 and the non-filtered air region 114 are communicated with each other under the condition of blocked air path, the liquid level difference between the filtered air region 112 and the non-filtered air region 114 of the liquid storage device 10 can be reduced or avoided, and the liquid level of the filtered air region 112 can be conveniently regulated.
Based on the above structure, the filtered air region 112 and the unfiltered air region 114 can always maintain the same liquid level, and the liquid exchange between the two can be carried out smoothly. In this way, the liquid in the filtered gas region 112 can be maintained in a flowing state to some extent without periodic replacement. Also, material dissolved in filtered gas region 112 can enter unfiltered gas region 114 and be recycled back into the environment, such as oxygen treatment device 20 described below.
In some further examples, the gas filtering area 112 is pre-populated with a bubble activation area 112a for activating gas from outside the enclosure 100 as it flows therethrough. The bubble active region 112a is only a subspace within the filtered air region 112. The bubble mobility area 112a can be determined based on the location of the gas as it enters the gas filtration zone 112 and the displacement of the gas as it moves downward in the gas filtration zone 112.
Of course, the air filtering area 112 of the present embodiment is also preset with a non-bubble active area 112a outside the bubble active area 112a, so as to form a liquid path channel between the non-bubble active area 112a and the non-air filtering area 114. The non-bubble active region 112a refers to a region that gas from outside the housing 100 does not reach when flowing through the gas filtering region 112.
Based on the structure, the air passage between the air filtering area 112 and the non-air filtering area 114 can be blocked skillfully, the liquid passage between the air filtering area 112 and the non-air filtering area 114 is kept smooth, and the structure has the advantages of exquisite structure, low manufacturing cost and the like.
In some alternative embodiments, the bubble active region 112a includes a sinking section 101 in which gas from outside the enclosure 100 moves down and a rising section 102 in which gas from outside the enclosure 100 moves up.
By presetting the sinking sub-area 101 and the rising sub-area 102 of the bubble moving area 112a, when the gas flow rate into the gas filtering area 112 needs to be adjusted, the position of the gas introduced into the gas filtering area 112 can be adjusted according to the position of the sinking sub-area 101, so that the gas does not overflow the sinking sub-area 101 during the downward movement.
In some further embodiments, the filtered air region 112 is horizontally juxtaposed with the unfiltered air region 114. And the air lock mechanism 200 is a partition-like structure located between the filtered area 112 and the non-filtered area 114 and extending downward from the lower surface of the top wall 120 of the box 100 to form a gap 116 with the upper surface of the bottom wall 130 of the box 100. Fig. 2 is a schematic structural view of a liquid storage device 10 according to another embodiment of the present invention. Fig. 3 is a schematic structural view of a liquid storage device 10 according to still another embodiment of the present invention. As shown in fig. 2 and 3, the dashed line L4 defines the gap 116 with the upper surface of the bottom wall 130 of the housing 100.
In some alternative embodiments, a bubble separation region 112b is pre-positioned within the bubble active region 112a, and the bubble separation region 112b is positioned above the non-filtered gas region 114 for filtered gas to flow out of the filtered gas region 112 therethrough.
Since the filtered gas section 112 communicates with the non-filtered gas section 114 in a liquid path, when the bubble separating section 112b is higher than the non-filtered gas section 114, no liquid exists in the bubble separating section 112b, and thus the bubble separating section 112b can serve as a gas collecting section in the cabinet 100 for collecting and discharging filtered gas.
The bubble active region 112a is in gas-path communication with other regions in the tank 100 (e.g., a liquid storage region in the tank 100) and is blocked from the liquid path, and the bubble active region 112a is in communication with the external environment of the tank 100, so as to discharge the gas filtered by the liquid storage space out of the tank 100. The bubble active region 112a is in gas-path communication with other regions in the case 100 and the liquid path is blocked, which means that the bubble active region 112a has a gas flow path with other regions in the case 100 and can exchange gas, but the liquid path between the bubble active region 112a and other regions in the case 100 is blocked and liquid in the case 100 cannot enter the bubble active region 112a. The bubble active region 112a is not used to contain liquid, but is used only to collect and discharge gas filtered by the liquid storage space.
With the above structure, the present embodiment provides a liquid storage device 10 capable of purifying gas, by defining the bubble separation area 112b in the tank 100 of the liquid storage device 10 and discharging gas by using the bubble separation area 112b, since the liquid in the liquid storage space does not overflow into the air channel of the bubble separation area 112b, the solution of the present embodiment can prevent the liquid storage device 10 from failing to discharge purified gas due to exhaust failure.
The top wall 120 of the non-filtered air region 114 of the box 100 extends upward to form a hollow cylindrical liquid inlet, so as to allow external liquid to flow into the liquid storage space through the liquid inlet. The top wall 120 of the gas-filtering area 112 of the case 100 is formed by rising upward to have an upper convex wall which defines the gas bubble separating area 112b higher than the top wall 120 of the gas-non-filtering area 114. And the highest point of the hollow cylindrical liquid inlet is located below the lowest point of the bubble separating region 112b.
By adopting the above scheme, the bubble separation area 112b can be defined above the liquid contained in the liquid storage space without physical separation, and the highest point of the liquid storage space is defined below the lowest point of the bubble separation area 112b, so that the liquid in the liquid storage space can be ensured not to enter the bubble separation area 112b all the time, which is beneficial to reducing or avoiding the air collection space from generating exhaust faults in the liquid injection process of the liquid storage device 10, thereby reducing the liquid injection risk.
As liquid is continuously injected into the reservoir space, the level of liquid in the reservoir space gradually increases. Even if the liquid level in the liquid storage space reaches the highest level, the highest point of the hollow columnar liquid inlet is lower than the lowest point of the bubble separation area 112b, so that the liquid in the liquid storage space can be ensured not to enter the bubble separation area 112b all the time.
By adopting the structure, the liquid path between the bubble separation area 112b and other areas can be cut off without arranging any shielding object or partition object between the bubble separation area 112b and other areas, and the structure has the advantages of exquisite structure, good liquid path partition effect, smooth gas path and the like.
Because the hollow columnar liquid inlet has a certain height, when liquid is injected into the liquid storage space, and the liquid level of the liquid storage space is lower than the lowest point of the hollow columnar liquid inlet, a certain distance is formed between the liquid level of the liquid storage space and the lowest point of the bubble separation area 112b, and the distance is greater than or equal to the height of the hollow columnar liquid inlet, so that the risk of liquid overflowing from the liquid contained in the liquid storage space to the bubble separation area 112b is further reduced.
In some optional embodiments, the top wall 120 of the air filtering region 112 is opened with an air inlet hole 122 for introducing air from the outside of the box 100 and an air outlet hole 124 for discharging filtered air. And the liquid storage device 10 may further include a filter 300 and an outlet 400.
The gas filtering pipe 300 is inserted into the gas filtering area 112 from the gas inlet hole 122 and extends to the upper part of the sinking sub-area 101 of the bubble activity area 112a to guide the gas to the sinking sub-area 101 of the gas filtering area 112, so that the soluble substances in the gas are dissolved in the bubble activity area 112a.
By adopting the above scheme, the gas to be filtered can reach the upper part of the sinking sub-zone 101 under the guidance of the gas filtering pipe 300, and move downwards in the sinking sub-zone 101, and then move upwards in the ascending sub-zone 102, so that the soluble substances in the gas are dissolved in the bubble moving area 112a, and the purification of the gas is completed. The purified gas may be intensively flowed to the bubble separating region 112b and flowed into a designated space under the guidance of the outlet pipe 400, thereby serving to adjust the oxygen content of the space.
Because outlet tube 400 extends only into bubble separation region 112b, and no liquid is present in bubble separation region 112b, the risk of liquid blockage at outlet tube 400 is reduced or avoided. For example, the outlet pipe 400 may extend to a height indicated by a dotted line L1.
In some further examples, the top wall 120 of the unfiltered gas region 114 is opened with a liquid inlet 126 communicating with the inner space and used for introducing external liquid. And the top end of the liquid inlet 126 is located below the bottom end of the gas outlet 400.
As liquid is continually injected into the inlet port 126, the liquid level within the tank 100 gradually increases. Even if the liquid level in the tank 100 reaches the highest level, since the top end of the liquid inlet 126 is lower than the bottom end of the gas outlet pipe 400, it is ensured that the liquid in the tank 100 does not enter the gas outlet pipe 400 at all times.
In some further embodiments, the liquid storage device 10 may further be provided with a liquid level sensor 900 for detecting the liquid level in the liquid storage space and sending a prompt signal when the liquid level in the liquid storage space falls to the liquid level indicated by the dotted line L3 or falls to the lowest point of the air filter tube 300 to prompt the liquid replenishment, so that the liquid level in the liquid storage space is always higher than the lowest point of the air filter tube 300. The liquid level sensor 900 may also send a prompt signal when the liquid level in the liquid storage space rises to the liquid level indicated by the dotted line L2 or rises to the lowest point of the air outlet pipe 400 to prompt the end of liquid replenishment, so that the liquid level in the liquid storage space is always lower than the highest point of the air outlet pipe 400. A buffer space may be defined between the dotted line L2 and the dotted line L1.
The liquid level sensor 900 may be provided in a plurality of numbers, for example, two, as shown in fig. 3, wherein the liquid level sensor 900 located above is used for sending a prompt signal when the liquid level in the liquid storage space rises to the liquid level indicated by the dashed line L2 to prompt the end of the liquid replenishment, and the liquid level sensor 900 located below is used for sending a prompt signal when the liquid level in the liquid storage space falls to the liquid level indicated by the dashed line L3. Of course, in other embodiments, the level sensors 900 may be provided as one, as shown in FIG. 2.

Wherein the cathode plate 700 serves to consume oxygen through an electrochemical reaction under the action of an electrolysis voltage.

In this embodiment, the electrochemical reaction of the oxygen treatment device 20 consumes water, and therefore, only water needs to be added to the oxygen treatment device 20, and the liquid in the liquid storage device 10 may be water.
The above examples of electrochemical reactions of the anode plate 600 and the cathode plate 700 are merely illustrative, and based on the understanding of the above embodiments, those skilled in the art should easily change the type of electrochemical reactions or develop the structure of the oxygen treatment device 20 suitable for other types of electrochemical reactions, and such changes and developments shall fall within the scope of the present invention.
