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 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.
The interior of the tank 100 defines a liquid storage space 110, which is open to air and closed to liquid, and a gas collection space 160. The reservoir 110 is used to allow gas from outside the tank 100 to flow therethrough for filtration. The reservoir 110 is for holding a liquid, such as water, or other solution. The kind of the liquid may be set according to the dissolution characteristics of the gas to be filtered and the dissolution characteristics of the impurities contained in the gas to be filtered, as long as the impurities contained in the gas to be filtered are made to be able to dissolve 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 110 may be water. The following description will be made in detail for various embodiments of the present invention by taking this as an example. 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 collecting space 160 communicates with the external environment of the case 100 to discharge the filtered air from the liquid storage space 110 out of the case 100. The liquid storage space 110 is in gas-path communication with the gas collecting space 160 and the liquid path is blocked, which means that an airflow path is provided between the liquid storage space 110 and the gas collecting space 160 and gas exchange is possible, but the liquid path between the liquid storage space 110 and the gas collecting space 160 is blocked, and liquid in the liquid storage space 110 cannot enter the gas collecting space 160. The air collecting space 160 is not used for containing liquid, but is used for collecting and discharging air filtered by the liquid storage space 110.
With the above structure, the present embodiment provides a liquid storage device 10 capable of purifying gas, a liquid storage space 110 and a gas collecting space 160 with communicated gas paths and blocked liquid paths are defined in a box 100 of the liquid storage device 10, the liquid storage space 110 is used for filtering gas, and the gas collecting space 160 is used for discharging gas, because the liquid in the liquid storage space 110 does not overflow to the gas path channel of the gas collecting space 160, the solution of the present embodiment can prevent the liquid storage device 10 from failing to discharge purified gas due to exhaust failure.
In some alternative embodiments, the case 100 is provided with a gas-liquid regulating portion, which defines the gas collecting space 160 above the liquid storage space 110 without physical obstruction, so that the gas flowing through the liquid storage space 110 diffuses upward to the gas collecting space 160. The term "without physical barrier" means that no barrier or partition is provided between the liquid storage space 110 and the gas collection space 160.
The gas-liquid regulating portion limits the highest point of the liquid storage space 110 below the lowest point of the gas collecting space 160, so that the liquid level in the liquid storage space 110 is always lower than the gas collecting space 160.
When the gas-liquid regulating part is used to define the gas collecting space 160 above the liquid storage space 110 without physical separation, and the highest point of the liquid storage space 110 is defined below the lowest point of the gas collecting space 160, it can be ensured that the liquid in the liquid storage space 110 does not enter the gas collecting space 160 all the time, which is beneficial to reducing or avoiding the air exhaust fault of the gas collecting space 160 caused by the liquid injection process of the liquid storage device 10, thereby reducing the risk of liquid injection.
As liquid is continually injected into the reservoir space 110, the liquid level within the reservoir space 110 gradually increases. Even if the liquid level in the liquid storage space 110 reaches the highest level, the highest point of the liquid storage space 110 is lower than the lowest point of the air collecting space 160, so that the liquid in the liquid storage space 110 can be ensured not to enter the air collecting space 160 all the time.
By adopting the structure, the liquid path between the liquid storage space 110 and the gas collecting space 160 can be cut off without arranging any shielding object or partition object between the liquid storage space 110 and the gas collecting space 160, and the structure has the advantages of exquisite structure, good liquid path partition effect, smooth gas path and the like.
In some alternative embodiments, the gas-liquid regulator includes a liquid level control region 170 communicating with the liquid storage space 110 and defining a highest point of the liquid storage space 110, and a raised region 180 raised above the liquid level control region 170. Wherein the level control region 170 is in communication with the environment outside the tank 100 to allow liquid outside the tank 100 to be injected therethrough into the reservoir 110. The interior of the elevated region 180 defines the plenum 160.
The bulging region 180 bulges above the level control region 170, meaning that the highest point of the level control region 170 is below the lowest point of the bulging region 180. Since the level control region 170 defines the highest point of the reservoir 110, the liquid level within the tank 100 is always below the lowest point of the bump region 180 when liquid is injected into the reservoir 110. For example, the raised area 180 may be defined by a portion of the top wall 120 of the enclosure 100 being raised upwardly. The level control zone 170 may be defined by another portion of the top wall 120 of the tank 100 being perforated.
In some examples, the liquid level control region 170 and the raised region 180 are disposed in a laterally offset manner along the tank 100 and respectively extend upward from the top wall 120 of the tank 100. For example, the liquid level control section 170 may be a hollow cylindrical liquid filling port formed to extend upward from the top wall 120 of the tank 100. The elevated region 180 may be an upwardly convex wall extending upwardly from the top wall 120 of the tank 100 above the top wall 120 of the non-elevated region 180 of the tank 100.
Because the hollow column-shaped liquid injection port has a certain height, when liquid is injected into the liquid storage space 110 and the liquid level of the liquid storage space 110 is lower than the lowest point of the hollow column-shaped liquid injection port, a certain distance is formed between the liquid level of the liquid storage space 110 and the lowest point of the gas collection space 160, and the distance is greater than or equal to the height of the hollow column-shaped liquid injection port, so that the risk of liquid overflowing from the liquid storage space 110 to the gas collection space 160 is further reduced.
In some alternative embodiments, the top wall 120 of the raised area 180 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 to the outside. The reservoir 10 may further include a filter 300 and an outlet 400.
The air filter 300 is inserted into the air collecting space 160 from the air inlet 122 and extends into the liquid storage space 110 to guide the air to the liquid storage space 110, so that the soluble substances in the air are dissolved in the liquid storage space 110.
The outlet pipe 400 is inserted into the gas collecting space 160 from the outlet hole 124 and extends above the lowest point of the gas collecting space 160 to guide the filtered gas out of the case 100 therethrough.
By adopting the above scheme, the gas to be filtered can reach the liquid storage space 110 under the guidance of the gas filtering pipe 300, and firstly move downwards in the liquid storage space 110 and then move upwards in the liquid storage space 110, so that the soluble substances in the gas are dissolved in the liquid storage space 110, and the purification of the gas is completed. The purified gas can be concentrated to the gas collecting space 160 and guided by the gas outlet pipe 400 to flow into a designated space, thereby playing a role in adjusting the oxygen content of the space.
Because the outlet tube 400 extends only above the lowest point of the gas collecting space 160 and no liquid exists in the gas collecting space 160, the risk of liquid blockage at the outlet tube 400 is reduced or avoided. For example, the outlet pipe 400 may extend to a height indicated by a dotted line in fig. 1 or a height indicated by a dotted line L1 in fig. 2 to 3.
In some further examples, the reservoir 110 includes a sunken partition 101 in which gas from outside the tank 100 moves downwardly, and a raised partition 102 in which gas flowing through the sunken partition 101 moves upwardly. The sunken sub-section 101 and the ascending sub-section 102 together form a bubble active area for gas from outside the tank 100 to move while flowing through the liquid storage space 110. The bubble motive area is a subspace within the reservoir 110. The bubble mobility area can be determined based on the location of the gas as it enters the reservoir 110 and the displacement of the gas as it moves down the reservoir 110.
Of course, the liquid storage space 110 of the present embodiment is also preset with a non-bubble active region outside the bubble active region, so as to form a liquid path channel between the non-bubble active region and the non-filtered region 114. The non-bubble active region refers to a region where gas from the outside of the case 100 does not reach when passing through the liquid storage space 110.
By presetting the sinking subarea 101 and the rising subarea 102 of the bubble moving area, when the gas flow rate in the gas filtering area 112 needs to be adjusted, the position of the gas in the gas filtering area 112 can be adjusted according to the position of the sinking subarea 101, so that the gas cannot overflow the sinking subarea 101 during the downward movement.
In one example, gas filter tube 300 extends above sink zone 101. The sinking section 101 has a predetermined longitudinal length to provide sufficient space for the gas to move downward. When the air filter 300 can guide the air to be filtered to the upper part of the sinking section 101, it can be ensured that the air to be filtered will not overflow the sinking section 101 after flowing out of the air filter 300 and moving downward in the liquid storage space 110.
In some optional embodiments, the liquid storage device 10 may further include an air blocking mechanism 200 disposed in the liquid storage space 110 to separate the liquid storage space 110 into an air-filtered region 112 and an air-unfiltered region 114. 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 the liquid storage space 110 outside the filtered air region 112.
In this embodiment, the air-filtering region 112 is a sub-space within the liquid storage space 110, and the air-non-filtering region 114 can be another sub-space within the liquid storage space 110.
The air-filtering area 112 and the non-air-filtering area 114, which are formed by the air-blocking mechanism 200 separating the liquid storage space 110 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 filtered air region 112 may be opened with an air inlet 122 and an air outlet 124 communicated with the environment outside the box 100, so that the air in the environment outside the box 100 may be introduced into the filtered air region 112 through the air inlet 122, and the air filtered by the filtered air region 112 may flow out of the box 100 through the air outlet 124.
With the above structure, the air resistance mechanism 200 is disposed in the case 100 of the liquid storage device 10, and the air resistance mechanism 200 is used to separate the liquid storage space 110 into the air filtering area 112 and the air non-filtering area 114 with blocked air paths, so that the function of purging gas 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 110 and is blocked from the air path in other areas of the liquid storage space 110, 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 this embodiment, a liquid level control section 170 is formed on the unfiltered gas section 114. That is, the liquid injection port is directly connected to the non-filtered gas area 114, for example, the non-filtered gas area 114 and the filtered gas area 112 may be arranged side by side along the transverse direction of the box 100, and a liquid level control area 170 is formed on the top of the non-filtered gas area 114 as the liquid injection port. The gas-unfiltered region 114 can also be provided with a liquid outlet to allow an internal liquid 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 resistance 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 liquid discharge process performed in the air non-filtering area 114 can be performed simultaneously, and mutual interference does not occur.
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 section 112 can be maintained in a flowing state to some extent without periodic replacement. Also, the dissolved species in the filtered gas region 112 can enter the unfiltered gas region 114 and be recycled back into the environment, such as the oxygen treatment device 20 described below.
The air lock mechanism 200 blocks all fluid paths between the bubble active region and the non-filtered region 114 and places the filtered region 112 outside the bubble active region (i.e., the non-bubble active region) in fluid communication with the non-filtered region 114. For example, the air lock mechanism 200 may employ a diaphragm-like structure to separate the bubble active region from the non-filtered region 114. When the non-air-filtering region 114 and the air-filtering region 112 are arranged in parallel along the horizontal direction and the air bubble activity region is located in the upper space of the air-filtering region 112, the plate surface of the air resistance mechanism 200 of the partition-plate structure may be a vertical surface.
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 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.
In some optional embodiments, the reservoir 10 further includes a liquid level management portion disposed in the reservoir 110 for monitoring the liquid level in the reservoir 110 such that the liquid level in the reservoir 110 is always higher than the outlet end of the air filter 300.
The outlet end of the air filter 300 is the end of the air filter 300 extending into the liquid storage space 110 for discharging air. For example, the fluid level management portion may be a fluid level sensor 900, which may send a prompt signal to instruct the user to replenish the fluid reservoir 10 or instruct the automatic fluid replenishing device to replenish the fluid reservoir 10 when the fluid level in the fluid reservoir 110 is detected to be lower than the outlet end of the air filter 300.
In some further embodiments, the level sensor 900 may signal when the liquid level in the reservoir 110 drops to a level indicated by the dashed line L3 or to the lowest point of the filter tube 300 to indicate fluid replacement such that the liquid level in the reservoir 110 is always higher than the lowest point of the filter tube 300. The liquid level sensor 900 can also send a prompt signal when the liquid level in the liquid storage space 110 rises to the liquid level marked by the dotted line L2 or rises to the lowest point of the air outlet pipe 400 to prompt the end of liquid replenishing, so that the liquid level in the liquid storage space 110 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 sensors 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 out 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 out 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.
