Description

Technical Field

[0001] This invention relates to preservation equipment, and more particularly to a liquid storage device with filtration and recovery functions, and a refrigerator having the same. Background Technology

[0002] For some reaction devices, such as those used to reduce oxygen levels inside a refrigerator through electrochemical reactions, the electrochemical reaction process requires the participation of an electrolyte, and the reaction process produces gas, which needs to be released into the external environment.

[0003] During the reaction, a large amount of heat is generated, causing the electrolyte to evaporate. This may result in trace amounts of electrolyte vapor being carried in the gas emitted from the reaction vessel. Most electrolytes are acidic or alkaline solutions and are corrosive. If the gas produced by the reaction device is directly released into the air without treatment, it may cause air pollution and endanger human health.

[0004] Furthermore, when the gas produced by the reaction device carries electrolyte vapor, the electrolyte will slowly leak out, which will lead to resource waste and increase production costs. Summary of the Invention

[0013] Optionally, the gas guide tube is a straight tube; or the gas guide tube is a vertically bent hook-shaped tube, and it has a straight tube section extending to the bottom section of the second liquid storage space and a bent tube section extending upward from the end of the straight tube section; the end of the bent tube section is slightly higher than the end of the straight tube section, and is used to guide the gas flowing through it upward.

[0014] Optionally, the housing is also provided with an air outlet located at the top of the housing, for discharging gas that has flowed through the air guide pipe and the second liquid storage space and has been separated into specific substances.

[0015] Optionally, the housing includes a first compartment having a top opening and a first compartment cover that closes the top opening of the first compartment, with an air inlet and an air outlet located on the first compartment cover at intervals.

[0017] Optionally, the second compartment cover is also provided with a liquid filling port, the wall of which extends downward to form a liquid filling groove; a portion of the groove wall extends downward at an angle, so that the bottom of the liquid filling groove forms a gradually narrowing opening.

[0018] Optionally, the bottom section of the liquid storage container is provided with a liquid supply port for discharging liquid to the external environment.

[0019] According to another aspect of the present invention, a refrigerator is also provided, which has a reaction device and includes: a liquid storage device as described in any of the above; wherein a filter is used to dissolve a specific substance component in the gas generated by the reaction device of the refrigerator in a second liquid storage space, and a first liquid storage space is used to supply liquid to the reaction device of the refrigerator.

[0020] The present invention provides a liquid storage device with filtration and recovery function and a refrigerator having the same. Since the liquid storage device has a filtration mechanism, a second liquid storage space communicating with a first liquid storage space of the liquid storage container is formed within the housing of the filtration mechanism. The filtration section of the filtration mechanism is used to dissolve specific substances in the gas from the external environment into the second liquid storage space so that they can enter the first storage space for recycling.

[0036] Figure 1This is a schematic structural diagram of a liquid storage device 20 with a filtration and recovery function according to an embodiment of the present invention. The liquid storage device 20 of this embodiment has a filtration and recovery function, which can separate and recover specific substances in the gas for use.

[0037] Figure 2 yes Figure 1 A schematic perspective view of the liquid storage device 20 shown. Figure 3 yes Figure 1 The diagram shows an exploded schematic view of the liquid storage device 20. The liquid storage device 20 generally includes a liquid storage container 200 and a filtration mechanism 400.

[0038] The liquid storage container 200 has a first liquid storage space 210 inside. The first liquid storage space 210 is used to store liquids, such as electrolytes containing specific components or water, but is not limited to these.

[0039] The filtration mechanism 400 has a housing 420 and a filter section 440. A second liquid storage space 421, communicating with the first liquid storage space 210, is formed within the housing 420. The filter section 440 is disposed in the second liquid storage space 421 and is used to dissolve specific components from gases originating from the external environment into the second liquid storage space 421, so that these components can enter the first liquid storage space 210 for recycling. The second liquid storage space 421 can also be used to store liquids, such as electrolytes containing specific components or water. The dissolution of specific components from gases originating from the external environment into the second liquid storage space 421 means dissolving them in the liquid stored within the second liquid storage space 421.

[0040] In this embodiment, the specific substance is a water-soluble substance. In some optional embodiments, the liquid composition stored in the first liquid storage space 210 and the second liquid storage space 421 can be adjusted according to the physicochemical properties of the specific substance to be separated.

[0041] Since the second liquid storage space 421 is connected to the first liquid storage space 210, specific substances dissolved in the gas from the external environment in the second liquid storage space 421 can enter the first liquid storage space 210 for recycling.

[0042] The liquid storage device 20 of this embodiment has a filter mechanism 400. The housing 420 of the filter mechanism 400 has a second liquid storage space 421 that communicates with the first liquid storage space 210 of the liquid storage container 200. The filter part 440 of the filter mechanism 400 is used to dissolve specific substances in the gas of the external environment into the second liquid storage space 421 so that they can enter the first storage space for recycling. Therefore, the present invention provides a liquid storage device 20 with a filtration and recycling function, which separates and recycles specific substances in the gas, thereby reducing or avoiding pollution caused by gas emissions and improving resource utilization efficiency.

[0043] In some alternative embodiments, the housing 420 is inserted into the first liquid storage space 210. For example, the liquid storage container 200 may be generally cuboid in shape, and the housing 420 may be inserted into the first liquid storage space 210 as an inner sleeve. The examples of the shapes of the liquid storage container 200 and the housing 420 are merely illustrative, and those skilled in the art should be able to easily expand upon them; they will not be listed here in detail.

[0044] Figure 4 yes Figure 1 A schematic structural diagram of the filtration mechanism 400 of the liquid storage device 20 shown. Figure 5 yes Figure 4 A schematic exploded view of the filtration mechanism 400 of the liquid storage device 20 shown.

[0045] The bottom of the housing 420 has a liquid outlet 422 for connecting to the first liquid storage space 210, allowing liquid in the second liquid storage space 421 to flow back to the first liquid storage space 210. This liquid outlet 422 serves as a "window" for material exchange between the two liquid storage spaces. The liquid outlet 422 ensures that the liquid level in the first liquid storage space 210 is consistent with the liquid level in the second liquid storage space 421, and facilitates the diffusion of liquid from the second liquid storage space 421 to the first liquid storage space 210.

[0046] Since the housing 420 is located inside the first liquid storage space 210 and is connected to the first liquid storage space 210 through the liquid outlet 422 located at the bottom of the housing 420, the liquid in the second liquid storage space 421 can flow downward through the liquid outlet 422 and back to the first liquid storage space 210 by its own gravity, which makes the recovery process of the liquid storage device 20 simple and effective.

[0047] In some optional embodiments, the housing 420 is also provided with an air inlet 423 for introducing gas from the external environment. This air inlet 423 can be located at the top of the housing 420, for example, on the cover of the housing 420, which can prevent leakage of the liquid stored in the second liquid storage space 421. In some optional embodiments, the air inlet 423 can also be located on the side wall of the housing 420, and above the normal liquid level of the second liquid storage space 421.

[0048] The filter section 440 is a gas guide tube that is inserted into the second liquid storage space 421 through the air inlet 423 and extends to the bottom section of the second liquid storage space 421 to guide external gas to the bottom section of the second liquid storage space 421. This allows specific components in the gas from the external environment to dissolve in the second liquid storage space 421 during the gas's ascent. Extending the gas guide tube to the bottom section of the second liquid storage space 421 allows the gas from the external environment to be transported to the depth of the liquid stored in the second liquid storage space 421, thereby extending the gas flow path within the second liquid storage space 421.

[0049] Since the filter section 440 is a gas guide tube, and it is inserted into the second liquid storage space 421 from the air inlet 423 of the housing 420 and extends to the bottom section of the second liquid storage space 421, the gas from the external environment is guided to the bottom section of the second liquid storage space 421. The gas flowing out of the gas guide tube can fully contact the liquid in the second liquid storage space 421 during the rising process, so that specific substances in the gas dissolve in the second liquid storage space 421. This allows the liquid storage device 20 to achieve a better filtration and purification effect with a compact and simple structure.

[0050] In this embodiment, the gas guide tube can be a straight tube with openings at both ends to facilitate the entry or exit of gas. It has a simple structure and excellent gas guiding effect.

[0051] In some alternative embodiments, the shape of the gas conduit can be changed to a vertically bent hook-shaped tube, having a straight section extending to the bottom section of the second liquid storage space 421 and a curved section extending upward from the end of the straight section. The end of the curved section is slightly higher than the end of the straight section, for guiding the gas flowing through it upward.

[0052] In other words, the gas guide tube in this embodiment can be shaped like a vertical hook, with the straight section resembling an umbrella shaft and the curved section resembling an umbrella handle connected to the end of the shaft. By bending the curved end upwards from the end of the straight section, the gas flowing out of the gas guide tube is guided upwards, thus making the direction of gas movement more definite. The fact that the end of the curved section is slightly higher than the end of the straight section means that the end of the curved section is still located in the bottom section of the second liquid storage space 421, which does not significantly shorten the gas flow path during the dissolution process.

[0053] In some optional embodiments, the housing 420 is further provided with a vent 424 for discharging gas that has flowed through the gas guide tube and the second liquid storage space 421 and has been separated into specific substances. The vent 424 is located at the top of the housing 420, for example, on the cover of the housing 420. The vent 424 is used to discharge the filtered gas to the external environment, for example, to the air in the external environment. In some embodiments, the inlet 423 and the vent 424 can both be circular openings. In this embodiment, the inlet 423 and the vent 424 can both be tubular through holes. The wall of the inlet 423 extends downwards continuously into the second liquid storage space 421, serving as a gas guide tube. In some embodiments, a gas outlet conduit can be connected to the vent 424 for guiding the gas.

[0054] In some alternative embodiments, the housing 420 may be integrally formed. In other alternative embodiments, the housing 420 may be composed of multiple different components connected together. For example, the housing 420 may include a first compartment 426 having a top opening and a first compartment cover 428 that closes the top opening of the first compartment 426. An air inlet 423 and an air outlet 424 are spaced apart from each other on the first compartment cover 428. The first compartment 426 may be a straight tube with a diameter larger than that of the air guide tube. The top end of the first compartment 426 is open and sealed to the first compartment cover 428. The bottom end of the first compartment 426 is closed and has the aforementioned liquid outlet 422. There may be at least one liquid outlet 422.

[0055] The air inlet 423, together with the air guide pipe and the air outlet 424, is covered by the first chamber 426 to form a sleeve structure. The bottom end of the air guide pipe is higher than the bottom end of the first chamber 426 to prevent the gas flowing out of the air guide pipe from escaping from the first chamber 426.

[0056] Setting an air inlet 423 and an air outlet 424 on the cover of the housing 420 can reduce the difficulty of opening holes, simplify the manufacturing process, and improve the gas emission efficiency.

[0057] In some optional embodiments, the liquid storage container 200 may be integrally molded, which helps to improve the sealing effect of the liquid storage container 200 and prevent leakage. In other optional embodiments, the liquid storage container 200 may be composed of multiple different components connected together. For example, the liquid storage container 200 may include a second compartment 260 with a top opening and a second cover 280 that closes the top opening of the second compartment 260. The second compartment 260 may be an open-top cuboid trough-shaped container with a volume larger than that of the first compartment 426.

[0058] Figure 6 yes Figure 3 The schematic structural diagram of the second compartment cover 280 of the liquid storage container 200 of the liquid storage device 20 shown is provided. Figure 6 (a) is a 3D diagram. Figure 6 (b) Main view Figure 6 (c) is a top view.

[0059] The second compartment cover 280 has an installation port 282. A hollow cylindrical external threaded interface 288 extends upward from the wall of the installation port 282. Because this external threaded interface 288 extends upward from the wall of the installation port 282, its upper edge is higher than the upper surface of the second compartment cover 280 and also higher than the upper edge of the filling tank 286 described below. This allows the highest liquid level during the filling process to be controlled below the upper edge of the external threaded interface 288.

[0060] The first compartment cover 428 has a closing cover plate 428a located above the first compartment body 426 and an annular internal threaded interface 428b extending downward from the outer periphery of the closing cover plate 428a. The closing cover plate 428a is used to cover the top opening of the first compartment body 426. The annular internal threaded interface 428b is screwed onto an external threaded interface 288, allowing the first compartment cover 428 to be detachably connected to the second compartment cover 280. That is, the annular internal threaded interface 428b is used to connect the first compartment cover 428 to the second compartment cover 280.

[0061] The first compartment 426 extends downward from the lower surface of the self-sealing cover plate 428a, passes through the external threaded interface 288, and is inserted into the first liquid storage space 210.

[0062] By screwing the first compartment cover 428 and the second compartment cover 280 together to seal the installation port 282, the installation and fixing process of the filter mechanism 400 can be simplified, and the filter mechanism can be installed in one step. At the same time, the first compartment body 426 can also function as an "air barrier".

[0063] Figure 7 yes Figure 1 The diagram illustrates the filtration and recovery process of the liquid storage device 20. The arrows in the diagram indicate the direction of gas flow or liquid flow. Due to the restriction of the "air barrier," the gas flowing out of the air guide pipe can only rise inside the first chamber 426 in the form of bubbles until it reaches the air outlet 424 of the first chamber cover 428 located above the first chamber 426 and is discharged, thus completing the filtration process. In some optional embodiments, the above-mentioned screw-on fastening installation method can also be changed to an interference fit or a sealing ring for sealing connection, as long as the seal ensures that it is watertight and airtight.

[0064] When the gas from the external environment contains soluble acidic or alkaline substances, these specific components are filtered and retained in the first chamber 426, and gradually diffuse into the liquid in the second chamber 260 through the liquid outlet 422 at the bottom of the first chamber 426. The first chamber 426 can serve as a replenishment chamber, and the liquid inside can be replenished and then transported back to the reaction site for reuse.

[0065] In some optional embodiments, the second compartment cover 280 may have a liquid filling port 284, the wall of which extends downward to form a liquid filling groove 286. Since the liquid filling groove 286 extends downward from the upper surface of the second compartment cover 280, and the external threaded interface 288 extends upward from the upper surface of the second compartment cover 280, when liquid is added to the second compartment 260 through the liquid filling port 284, even if the liquid filling process causes the second compartment 260 to overflow, the liquid level at the time of overflow will not exceed the external threaded interface 288.

[0066] A portion of the wall of the filling tank 286 extends downwards at an angle, creating a tapering opening at the bottom. In other words, the filling tank is a sloping through-hole of a certain depth, facilitating user observation of the liquid level during filling. A liquid level indicator is located on the downward-sloping wall to indicate the liquid level during the filling process. For example, this indicator could be designed as a "maximum liquid level mark" to indicate to the user that the tank is full.

[0067] The bottom section of the liquid storage container 200 is provided with a liquid supply port 262 for discharging liquid to the external environment. The liquid supply port 262 can be located in the bottom section of the second compartment 260. That is, while storing liquid, the liquid storage container 200 can also supply liquid to the external environment via the liquid supply port 262 for use, which is beneficial for optimizing the production process and improving production efficiency. For example, the liquid supply port 262 can be connected via pipeline to an electrochemical deoxygenation device that performs an electrochemical reaction, and can replenish the electrochemical deoxygenation device with liquid, such as electrolyte or water.

[0068] A liquid supply port 262 is provided at the bottom section of the second chamber 260, which allows the liquid in the second chamber 260 to flow out automatically by gravity, which helps to improve the automation of the liquid supply process.

[0069] In some alternative embodiments, the edge of the second compartment cover 280 has outwardly protruding protrusions 287 for applying force. The user can apply force to the second compartment cover 280 by grasping or other actions, thereby realizing the assembly and disassembly process between the second compartment cover 280 and the second compartment body 260.

[0070] An elastic sealing ring may be provided around the periphery of the closure between the second compartment cover 280 and the second compartment body 260, so as to facilitate sealing by pressing the second compartment cover 280 and the second compartment body 260 together, and prevent the second compartment body 260 from leaking water.

[0071] Figure 8 This is a schematic block diagram of a refrigerator 1 according to an embodiment of the present invention. The refrigerator 1 has a reaction device 10. The refrigerator 1 generally includes a liquid storage device 20 as described in any of the above embodiments. The reaction device 10 can be an electrochemical deoxygenation device, used to consume oxygen inside the refrigerator 1 through an electrochemical reaction, thereby reducing oxygen levels. In some optional embodiments, the reaction device 10 can be replaced with other devices as needed, such as a deodorizing reaction device 10.

[0072] An electrochemical deoxygenation device may include a reaction vessel 500, the interior of which forms the site for the electrochemical reaction. The reaction vessel 500 may contain electrochemical reaction elements (anode plates, cathode plates, etc.) and also stores an electrolyte, such as a sodium hydroxide solution. The anode plates and cathode plates are immersed in the electrolyte.

[0073] The cathode plate is connected to the airflow within the storage compartment of refrigerator 1. When energized, the cathode plate consumes oxygen within the storage compartment through an electrochemical reaction. For example, oxygen in the air can undergo a reduction reaction at the cathode plate: O₂ + 2H₂O + 4e⁻. - →4OH - .

[0074] An anode plate and a cathode plate are disposed alternately within a reaction vessel 500. When energized, the anode plate provides reactants (e.g., electrons) to the cathode via an electrochemical reaction, generating oxygen. The OH- produced by the cathode plate... - An oxidation reaction can occur at the anode plate to generate oxygen, i.e., 4OH⁻. - →O2 + 2H2O + 4e - Oxygen can be discharged through the vent 510 on the reaction vessel 500.

[0075] The filter section 440 is used to dissolve specific components of the gas from the electrochemical deoxygenation device of the refrigerator 1 into the second liquid storage space 421. For example, the exhaust port 510 of the reaction vessel 500 is connected to the air inlet 423 of the shell 420, so that the oxygen generated in the reaction vessel 500 enters the gas guide pipe and is filtered, so that the electrolyte carried in the oxygen is retained in the second liquid storage space 421.

[0076] The first liquid storage space 210 is used to supply liquid to the electrochemical deoxygenation device of the refrigerator 1. For example, a liquid replenishment port 520 may be provided on the reaction vessel 500, and the liquid supply port 262 of the second compartment 260 is connected to the liquid replenishment port 520 of the reaction vessel 500, so that the liquid in the first liquid storage space 210 flows sequentially through the liquid supply port 262 and the liquid replenishment port 520 and then enters the reaction vessel 500. A liquid level switch 100 may be provided inside the reaction vessel 500 to automatically open and close the liquid replenishment port 520 according to the liquid level in the reaction vessel 500.

[0077] In this embodiment, since the electrochemical reaction of the electrochemical deoxygenation device consumes water, the liquid in the first storage space 210 can be water directly, or it can be converted into an electrolyte. Since the electrolyte in the electrolyte carried by oxygen is soluble in water, the liquid in the second storage space 421 can also be water directly, or it can be converted into an electrolyte.

[0078] By combining the liquid storage device 20 with the electrochemical deoxygenation device, water can be automatically replenished to the electrochemical deoxygenation device. At the same time, acidic or alkaline components in the waste gas generated by the electrochemical deoxygenation device can be removed, and the electrolyte that was originally lost can be recovered and reused. The whole process does not require professional personnel to operate, nor does it require the use of electronic components. The whole system has the advantages of integration, modularity and low cost.

[0079] Since the liquid storage device 20 has a filtration and recovery function and can output liquid to the external environment through the liquid supply port 262, when the liquid storage device 20 is combined with the electrochemical deoxygenation device of the refrigerator 1, the gas discharged by the electrochemical deoxygenation device can be guided to the second liquid storage space 421, and specific substances in the gas can be separated and recycled. When the electrolyte in the electrochemical deoxygenation device is insufficient, the liquid in the first liquid storage space 210 can be used for replenishment. Therefore, the refrigerator 1 of this embodiment can solve the problems of difficult replenishment and electrolyte loss in the deoxygenation process.

[0080] In some alternative embodiments, the liquid storage device 20 may also be used in conjunction with other reaction devices 10, and is not limited to the electrochemical deoxygenation device of the above embodiments.

[0081] The liquid storage device 20 is independent of the reaction device 10, which avoids the risks associated with directly adding liquid to the reaction device 10.

[0082] By using a gas guide tube and a housing 420 in conjunction, water can be used for gas filtration, which avoids the use of consumable filter media and eliminates the need to replace the filter media, thus saving costs.

[0083] The design capacity of the liquid storage container 200 can meet the liquid replenishment needs of the reaction device 10 within a set time period.

[0084] Figure 9 This is a schematic structural diagram of a reaction system according to an embodiment of the present invention. The reaction system generally includes a reaction apparatus 10 and a liquid storage device 20 as described in any of the above embodiments. The reaction system of this embodiment can achieve the filtration and recycling of waste gas from the chemical reaction process.

[0085] like Figure 9 As shown, the liquid supply port 262 of the liquid storage container 200 and the liquid replenishment port 520 of the reaction container 500 are connected by a liquid guide pipe, so that the first liquid storage space 210, the liquid supply port 262, the liquid replenishment port 520 and the internal space of the reaction container 500 form a liquid delivery channel.

[0086] The replenishment port 520 is lower than the supply port 262 of the storage container 200, which allows the liquid in the first storage space 210 to flow downwards to the replenishment port 520 by its own gravity. The replenishment port 520 is located at the top of the reaction vessel 500, which can prevent leakage from the reaction vessel 500.

[0087] The top of the reaction vessel 500 is also provided with an exhaust port 510, which is connected to the second liquid storage space 421 through an air pipe. One end of the air pipe is connected to the exhaust port 510, and the other end is connected to the air inlet 423 of the shell 420.

[0088] Figure 10 This is a schematic structural diagram of a liquid level switch 100 for a reaction system according to an embodiment of the present invention.

[0089] In some optional embodiments, the reaction system may further include a level switch 100, which has a switch body 120 disposed within the reaction vessel 500 and is used to open or close the replenishment port 520 according to the movement of the liquid level within the reaction vessel 500, thereby allowing or preventing liquid from the first storage space 210 from entering the reaction vessel 500 through the replenishment port 520. In other words, the level switch 100 is used to control the opening and closing of the replenishment port 520. That is, the level switch 100 acts as a gate for the aforementioned liquid delivery channel, serving to open or close the liquid delivery channel. The switch body 120 of the level switch 100 moves according to the liquid level in the reaction vessel 500, thereby closing or opening the replenishment port 520. The opening and closing process of the replenishment port 520 does not require electrical control.

[0090] Since the liquid level switch 100 can move automatically according to the liquid level of the reaction vessel 500 to open and close the liquid replenishment port 520, thereby opening and closing the liquid delivery channel, the reaction system of this embodiment has an automatic liquid replenishment function, and there is no need to add liquid to the reaction vessel 500 from the external environment.

[0091] The switch body 120 is movably disposed below the liquid inlet 520, and when the liquid level in the reaction vessel 500 rises, it rises to press against the lower periphery of the liquid inlet 520 to close the liquid inlet 520, and when the liquid level in the reaction vessel 500 drops, it falls away from the lower periphery of the liquid inlet 520 to open the liquid inlet 520.

[0092] In other words, the switch body 120 can rise and abut against the lower periphery of the liquid inlet 520 when the liquid level in the reaction container 500 rises, thereby sealing the liquid inlet 520 and preventing the liquid in the first liquid storage space 210 from passing through the liquid inlet 520. It can also fall down when the liquid level in the reaction container 500 drops, thereby deviating from and opening the liquid inlet 520, so that the liquid in the first liquid storage space 210 can flow downward into the reaction container 500 by gravity.

[0093] The level switch 100 also includes a float 110, which is fixedly connected to or integral with the switch body 120, and is used to move the switch body 120 within the reaction vessel 500 by floating or sinking. In other words, the switch body 120 is "driven" by the float 110, and the power required for the float 110 to move is determined by the buoyancy it experiences within the reaction vessel 500.

[0094] For example, a portion of float 110 is immersed in the liquid, thus experiencing buoyancy from the liquid. When the liquid level inside the container changes, the buoyancy on float 110 also changes, causing a change in the resultant force of the buoyancy and gravity on float 110. For instance, when the liquid level in reaction vessel 500 decreases, the buoyancy on float 110 decreases. If the resultant force of the buoyancy and gravity on float 110 is downward, it will cause float 110 to move downward. Conversely, it will cause float 110 to move upward. Float 110 can rise or fall vertically, or it can rise or fall along a curve.

[0095] In some alternative embodiments, the float 110 is rotatably arranged about an axis. That is, the float 110 in this embodiment does not move up and down along a straight line, but rises or falls by rotating about an axis. With this design, it is only necessary to pivotally connect the float 110 to a fixed axis, without the need to install guide components with high dimensional accuracy. It has the advantages of compact structure, simple assembly process and good device reliability.

[0096] Since the float 110 is rotatable around an axis and has a clear and defined movement trajectory, the float 110 and the switch body 120 in this embodiment can easily move along a clear and defined movement trajectory, thereby improving the reliability of the liquid level switch 100 and reducing or avoiding problems such as poor sealing caused by the free movement of the float 110.

[0097] The level switch 100 may further include a rotating shaft 130 and a connector 140.

[0098] The rotating shaft 130 is fixed to the reaction vessel 500. For example, the rotating shaft 130 can be fixed to the internal space of the reaction vessel 500 and fixedly connected to the inner wall of the reaction vessel 500.

[0099] In some alternative embodiments, the rotating shaft 130 can also be detachably fixed to the reaction vessel 500, which can adjust the height of the rotating shaft 130 as needed, thereby adjusting the liquid level in the vessel at the start of liquid replenishment.

[0100] The connector 140 is fixedly connected to the float 110 or is an integral part of the float 110. It has a shaft hole for the rotating shaft 130 to be inserted into and rotatably engaged to achieve a rotatable connection. In other words, the connector 140 assembles the rotating shaft 130 and the float 110 into an organic whole, so that the float 110 can rotate around the rotating shaft 130.

[0101] By opening a shaft hole in the connector 140 and rotatably engaging the rotating shaft 130 with the shaft hole, the float 110 can be rotatably assembled onto the rotating shaft 130. The structure is ingenious and the process is simple.

[0102] The switch body 120 is rod-shaped. The connector 140 also has a mounting opening for a portion of the switch body 120 to be inserted into for a fixed assembly. In other words, a portion of the switch body 120 is indirectly and fixedly connected to the float 110 by being fixedly assembled with the connector 140. For example, the portion of the switch body 120 can be assembled with the mounting opening of the connector 140 by an interference fit.

[0103] The rotating shaft 130 and the switch body 120 are respectively assembled to the connector 140 which is fixedly connected to the float 110 or is an integral part of the float 110, thereby forming the liquid level switch 100, which has a strong overall structure.

[0104] The present invention provides a liquid storage device 20 with filtration and recycling function and a refrigerator 1 having the same. Since the liquid storage device 20 has a filtration mechanism 400, a second liquid storage space 421 is formed in the housing 420 of the filtration mechanism 400, which communicates with the first liquid storage space 210 of the liquid storage container 200. The filtration part 440 of the filtration mechanism 400 is used to dissolve specific substances in the gas of the external environment into the second liquid storage space 421 so that they can enter the first storage space for recycling. Therefore, the present invention provides a liquid storage device 20 with filtration and recycling function, which can separate and recycle specific substances in the gas, thereby reducing or avoiding pollution caused by gas emissions and improving resource utilization efficiency.

[0105] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.
