[0032] See Figures 1 to 4 , Figures 1 to 4 This is a schematic diagram of the structure of the first embodiment of the liquid storage device in this application. The structure of the first embodiment of the liquid storage device will be described in detail below.

[0033] See Figures 1 to 4 The liquid storage device 100 includes a shell body 1, a first cover 2, a second cover 3, and a first partition 4. The first cover 2 is connected to one side of the shell body 1, and the second cover 3 is connected to the other side of the shell body 1. Specifically, in this embodiment, the first cover 2 covers one opening of the shell body 1 and is fixedly connected to one side of the shell body 1 by welding, and the second cover 3 covers the other opening of the shell body 1 and is fixedly connected to the other side of the shell body 1 by welding. The connection between the first cover 2 and the shell body 1 is sealed. The connection between the second cover portion 3 and the shell body portion 1 is sealed. This sealing can be achieved by welding or by setting a sealing ring or sealant between the two. In this embodiment, the shell body portion 1, the first cover portion 2, and the second cover portion 3 are processed separately and then assembled. Of course, the first cover portion 2 and the shell body portion 1 can also be integrally formed and then assembled with the second cover portion 3, or the second cover portion 3 and the shell body portion 1 can be integrally formed and then assembled with the first cover portion 2.

[0034] See Figures 1 to 3 The liquid storage device 100 has a first orifice 101 and a second orifice 102. The first orifice 101 serves as an inlet of the liquid storage device, and the second orifice 102 serves as an outlet of the liquid storage device. When the liquid storage device is independently installed in the air conditioning system, the connecting pipe in the system can be connected to the inlet and / or outlet of the liquid storage device. When the liquid storage device is integrated with other components, the interface connection on the assembled components can be connected to the inlet and / or outlet of the liquid storage device. See also... Figures 1 to 3In this embodiment, the first opening 101 is formed on the first cover portion 2, and the second opening 102 is formed on the second cover portion 3. Of course, the first opening 101 and the second opening 102 can also be formed on the outer wall of the shell body portion 1. In addition, in this embodiment, the central axis of the first opening 101 and the central axis of the second opening 102 are arranged parallel to each other.

[0035] See Figure 3 and Figure 9 The first opening 101 is located on one side of the first partition 4, and the second opening 102 is located on the other side of the first partition 4; one side of the first partition 4 is connected to the inner wall of the shell body 1, and the other side of the first partition 4 is connected to the inner wall of the shell body 1. This connection can be direct or indirect, including indirect connection via an adapter or via an arc transition connection; see [link to other documentation]. Figure 3 The liquid storage device 100 includes a first receiving portion 10 and a second receiving portion 20. The first receiving portion 10 has a first cavity 103, and the second receiving portion 20 has a second cavity 203. The first cavity 103 is located on one side of the first partition 4, and the second cavity 203 is located on the other side of the first partition 4. The first cavity 103 and the second cavity 203 are arranged side by side and communicate with each other. A first orifice 101 communicates with the first cavity 103, and a second orifice 102 communicates with the second cavity 203. In this way, on the one hand, the arrangement of the first partition helps to improve the mechanical strength of the shell body, thereby improving the pressure resistance of the shell body and reducing the deformation of the shell. On the other hand, in this embodiment, the first cavity 103 and the second cavity 203 are arranged separately, which helps to reduce the height of the liquid storage device. Therefore, when the installation space of the liquid storage device in the height direction is limited, it is beneficial to enable the liquid storage device to be installed in the air conditioning system in the height direction.

[0036] See Figure 3 In this embodiment, the first cavity 103 includes a first sub-cavity 1031, a second sub-cavity 1032, and a third sub-cavity 1033, and the second cavity 203 includes a fourth sub-cavity 2031, a fifth sub-cavity 2032, and a sixth sub-cavity 2033. Specifically, the first sub-cavity 1031 and the fourth sub-cavity 2031 are formed in the first cover portion 2, the second sub-cavity 1032 and the fifth sub-cavity 2032 are formed in the shell body portion 1, and the third sub-cavity 1033 and the sixth sub-cavity 2033 are formed in the second cover portion 3. In this way, it is beneficial to relatively increase the volume of the first cavity 103 and the second cavity 203, thereby improving the liquid storage capacity of the liquid storage device. Of course, the first cavity 103 may only include the second sub-cavity 1032, and / or the second cavity 203 may only include the fifth sub-cavity 2032.

[0037] The following section will provide a detailed description of the structure of the main shell, the first cover, and the second cover mentioned above.

[0038] See Figure 5 In this embodiment, a portion of the outer surface of the shell body 1 is planar. Specifically, the shell body 1 includes a first planar portion 11 and a second planar portion 12, which are arranged in parallel. This makes the shape of the shell body 1 relatively regular, thus improving the utilization rate of the system installation space when the liquid storage device is installed in the system. In this embodiment, one end of the first planar portion 11 and one end of the second planar portion 12 are connected by a first connecting portion 13, and the other end of the first planar portion 11 and the other end of the second planar portion 12 are connected by a second connecting portion 14. A portion of the outer surface of the first connecting portion 13 is arc-shaped, and a portion of its outer surface is planar. A portion of the outer surface of the second connecting portion 14 is arc-shaped, and a portion of its outer surface is planar. See also: Figure 5 In this embodiment, one side of the first partition 4 is connected to the inner surface of the first flat portion 11, and the other side of the first partition 4 is connected to the inner surface of the second flat portion 12. Specifically, in this embodiment, one side of the first partition 4 is smoothly connected to the inner surface of the first flat portion 11 by an arc, and the other side of the first partition 4 is smoothly connected to the inner surface of the second flat portion 12 by an arc. This helps to avoid stress concentration. See also Figure 3 and Figure 9 The first partition 4 is perpendicular to the first flat part 11, the second cavity 1032 is located on one side of the first partition 4, and the fifth cavity 2032 is located on the other side of the first partition 4. In addition, in this embodiment, the first partition 4 can be integrally formed with the shell body 1, so that the first partition 4 and the shell body 1 can be directly formed on the profile, which is convenient for processing. Of course, the first partition 4 and the shell body 1 can also be set separately and then fixedly connected. Here, "set separately" means that the first partition 4 and the shell body 1 are formed separately and then assembled.

[0039] See Figure 6 and Figure 7 The first cover portion 2 includes a first body portion 21, a first protrusion 22, and a second protrusion 23. The outer surfaces of the first protrusion 22 and the second protrusion 23 protrude from the lower surface 211 of the first body portion 21. The outer surfaces of the first protrusion 22 and the second protrusion 23 are located inside the outer surface of the first body portion 21. (See also...) Figure 3 The first protrusion 22 is located in the first cavity 103, and the second protrusion 23 is located in the second cavity 203; see also Figure 3 and Figure 6 In this embodiment, the first cavity 1031 includes the area enclosed by the first protrusion 22, and the fourth cavity 2031 includes the area enclosed by the second protrusion 23; see also Figure 3 and Figure 6In this embodiment, the first cover portion 2 is projected orthogonally in a direction parallel to the lower surface 211 of the first cover portion 2, and the projection of the first opening 101 is located in the first cavity 1031.

[0040] See Figure 6 and Figure 7 In this embodiment, the root 221 of the inner surface of the first protrusion 22 and the root 231 of the inner surface of the second protrusion 23 are located on the same plane. The root 221 of the inner surface of the first protrusion 22 and the root 231 of the inner surface of the second protrusion 23 are closer to the upper surface 212 of the first body part 21 than the lower surface 211 of the first body part 21. This is beneficial to increase the volume of the first cavity 1031 and the fourth cavity 2031. Of course, the root 221 of the inner surface of the first protrusion 22 and the root 231 of the inner surface of the second protrusion 23 can also be flush with the lower surface 211 of the first body part 21, or the lower surface 211 of the first body part 21 can also be closer to the upper surface 212 of the first body part 21 than the root 221 of the inner surface of the first protrusion 22 and / or the root 231 of the inner surface of the second protrusion 23. In this embodiment, both the first protrusion 22 and the second protrusion 23 are annular. The first protrusion 22, the second protrusion 23 and the first body part 21 are integrally formed. Of course, the first protrusion 22 can also be integrally formed with the first body part 21 to form a cover part, and the second protrusion 23 can be integrally formed with the first body part 21 to form a cover part, and then each can be assembled with the shell body part.

[0041] See Figure 8 and Figure 9 The second cover portion 3 includes a second body portion 31, a third protrusion 32, and a fourth protrusion 33. The outer surfaces of the third protrusion 32 and the fourth protrusion 33 protrude from the lower surface 311 of the second body portion 31. The outer surfaces of the third protrusion 32 and the fourth protrusion 33 are located inside the outer surface of the second body portion 31. In this embodiment, the third protrusion 32 is located inside the lower surface 311 of the second body portion 31. Figure 3 The first cavity 103 and the fourth protrusion 33 are located in the middle. Figure 3 The second cavity 203; see also Figure 8 and Figure 9 The third cavity 1033 includes the area enclosed by the third protrusion 32, and the sixth cavity 2033 includes the area enclosed by the fourth protrusion 33; see also Figure 3 and Figure 8 In this embodiment, the second cover portion 3 is projected orthogonally in a direction parallel to the upper surface 311 of the second cover portion 3, and the projection of the second opening 102 is located in the sixth cavity 2033.

[0042] See Figure 9In this embodiment, the root 321 of the inner surface of the third protrusion 32 and the root 331 of the inner surface of the fourth protrusion 33 are located on the same plane. The root 321 of the inner surface of the third protrusion 32 and the root 331 of the inner surface of the fourth protrusion 33 are closer to the lower surface 312 of the second body part 31 than the upper surface 311 of the second body part 31. That is, the root 321 of the inner surface of the third protrusion 32 and the root 331 of the inner surface of the fourth protrusion 33 are lower than the upper surface 311 of the second body part 31. The upper surface 311 of the body portion 31 facilitates an increase in the volume of the third cavity 1033 and the sixth cavity 2033. Alternatively, the root 321 of the inner surface of the third protrusion 32 and the root 331 of the inner surface of the fourth protrusion 33 can be flush with the upper surface 311 of the second body portion 31, or the root 321 of the inner surface of the third protrusion 32 and the root 331 of the inner surface of the fourth protrusion 33 can be higher than the upper surface 311 of the second body portion 31. In this embodiment, the third protrusion 32, the fourth protrusion 33, and the second body portion 31 are integrally formed. Alternatively, the third protrusion 32 can be integrally formed with the second body portion 31 to form a cover portion, and the fourth protrusion 33 can be integrally formed with the second body portion 31 to form a cover portion, and then each can be assembled with the shell body portion.

[0043] See also Figure 3 , Figure 5 , Figure 7 and Figure 9 The upper end of the shell body 1 abuts against the lower surface 211 of the first body 21 of the first cover 2. The upper end face of the first partition 4 is located between the first protrusion 22 and the second protrusion 23. The upper end face of the first partition 4 is higher than the end faces of the first protrusion 22 and the second protrusion 23. In this embodiment, the first cover 2 is fixedly connected to the shell body 1 and sealed by welding the connection between the lower surface of the first body 21 and the upper end face of the shell body 1. (See also...) Figure 3 , Figure 5 , Figure 7 and Figure 9 The lower end of the shell body 1 abuts against the upper surface 311 of the second body 31 of the second cover 3. The lower end face of the first partition 4 is located between the third protrusion 32 and the fourth protrusion 33. The lower end face of the first partition 4 is lower than the end face of the third protrusion 32 and the end face of the fourth protrusion 33. In this embodiment, the second cover 3 is fixedly connected to the shell body 1 and sealed by welding the connection between the upper surface 311 of the second body 31 and the lower end face of the shell body 1.

[0044] See Figures 3 to 5In this embodiment, the liquid storage device 100 further includes a first connecting portion 41, which is formed in the first partition 4. The first connecting portion 41 extends through the first partition 4 along its thickness direction. It extends from the lower end face of the first partition 4 towards the upper end face of the first partition 4, and its opening is located on the lower end face of the first partition 4. The first connecting portion 41 connects the first cavity 103 and the second cavity 203. (See also...) Figure 4 and Figure 9 In this embodiment, the liquid storage device 100 further includes a second connecting portion 34, which is connected to the first connecting portion 41. The second connecting portion 34 is formed on the second cover portion 3. The first opening of the second connecting portion 34 is located on the inner surface of the third protrusion 32, and the second opening of the second connecting portion 34 is located on the inner surface of the fourth protrusion 33. The second connecting portion 34 connects the third sub-cavity 1033 and the sixth sub-cavity 2033. In this embodiment, the arrangement of the first connecting portion 41 and the second connecting portion 34 enables the first cavity 103 and the second cavity 203 to communicate, and also increases the communication area when the first cavity 103 and the second cavity 203 are connected. Of course, only the first connecting portion 41 or the second connecting portion 34 can be provided. When only the first connecting portion 41 is provided, the opening of the first connecting portion 41 can be left blank on the lower end face of the first partition 4, that is, the first connecting portion 41 can be provided through the thickness direction of the first partition 4. Of course, in this case, the first connecting portion 41 can also be formed with an opening on the lower end face of the first partition 4. When only the second connecting portion 34 is provided, the lower end face of the first partition 4 abuts against the plane where the end face of the third protrusion 32 and / or the end face of the fourth protrusion 33 are located.

[0045] See Figure 3 The liquid storage device 100 also includes a first filter device 5, a first baffle 6, and a second baffle 7. The first baffle 6, the second baffle 7, and the first filter device 5 are located in the first cavity 103. Specifically, the first baffle 6, the second baffle 7, and the first filter device 5 are located in the second compartment 1032. The first filter device 5 can filter moisture and impurities in the medium. The first filter device 5 is located between the first baffle 6 and the second baffle 7. One side of the first baffle 6 and one side of the second baffle 7 are fixedly connected to the side wall of the first receiving part 10. The other side of the first baffle 6 and the other side of the second baffle 7 are fixedly connected to the first partition 4. The first baffle 6 and the second baffle 7 are vertically distributed. The first baffle 6 is closer to the first opening 101 than the second baffle 7. The lower end of the first filter device 5 is located above the first connecting part 41. This ensures that the medium entering the first cavity passes through the first filter device 5 before flowing into the first connecting part 41. In this embodiment, the first filter device 5 is placed inside the first cavity 103. Of course, the first filter device 5 can also be placed outside the liquid storage device, in which case the liquid storage device only has the function of storing liquid medium.

[0046] The principle of the liquid storage device in the first embodiment will be described in detail below.

[0047] See Figure 3 Liquid or gas-liquid mixture refrigerant enters the first chamber 103 through the first orifice 101, and then flows through the first filter device 5. The water and impurities in the liquid or gas-liquid mixture refrigerant are filtered out by the first filter device 5. The filtered liquid or gas-liquid mixture refrigerant flows into the second chamber 203 through the first flow section 41, then flows into the second orifice 102 from the second chamber 203, and finally flows out from the second orifice 102.

[0048] See Figure 10 , Figure 10 This is a cross-sectional structural diagram of a second embodiment of the liquid storage device in this application. The structure of the second embodiment of the liquid storage device will be described in detail below.

[0049] See Figure 10 Compared to the first embodiment of the liquid storage device, in this embodiment, the liquid storage device 100a further includes a second filter device 8, which is located in the second cavity 203. The first filter device 5 is capable of filtering water, and the second filter device 8 is capable of filtering impurities. (See also...) Figure 10 In this embodiment, the second filter device 8 is fixedly connected to the second cover part 3. The medium in the second cavity 203 flows into the second orifice 102 after being filtered by the second filter device 8, and then flows out from the second orifice 102. Other structural features in this embodiment can be referred to the first embodiment of the liquid storage device, and will not be described in detail here.

[0050] See Figures 11 to 13 , Figures 11 to 13 This is a cross-sectional structural diagram of the third embodiment of the liquid storage device in this application. The structure of the third embodiment of the liquid storage device will be described in detail below.

[0051] See Figures 11 to 13 Compared to the second embodiment of the liquid storage device, in this embodiment, both the first orifice 101 and the second orifice 102 are formed on the first cover portion 2, and the central axis of the first orifice 101 and the central axis of the second orifice 102 are arranged parallel to each other; the first orifice 101 is located on one side of the first partition 4, and the second orifice 102 is located on the other side of the first partition 4; see also Figure 13 In this embodiment, the liquid storage device 100b also includes a liquid suction tube 9, at least a portion of which is located in the second cavity 203. The liquid suction tube 9 is fixedly connected to the first cover portion 2. The liquid suction tube 9 includes a liquid suction channel 91, which connects the second opening 102 and the second cavity 203.

[0052] See Figure 13In this embodiment, the liquid storage device 100b further includes a first filter device 5 and a second filter device 8. The first filter device 5 is located in the first chamber 103, and the second filter device 8 is located in the second chamber. The first filter device 5 can filter water, and the second filter device 8 can filter impurities. The second filter device 8 is connected to one end of the suction tube 9. The medium in the second chamber 203 flows into the suction channel 91 after being filtered by the second filter device 8, and then flows into the second orifice 102 from the suction channel 91. Additionally, see... Figure 13 In this embodiment, the lower end face of the second filter device 8 is lower than the top of the first connecting part 41, so that the medium located below the top of the first connecting part 41 can be filtered by the second filter device 8, and thus the medium located below the top of the first connecting part 41 can also flow out through the suction channel 91 of the suction tube 9.

[0053] See Figures 14 to 16 See Figures 14 to 16 This is a cross-sectional structural diagram of the fourth embodiment of the liquid storage device in this application. The structure of the fourth embodiment of the liquid storage device will be described in detail below.

[0054] See Figures 14 to 16 In this embodiment, compared with the first embodiment of the liquid storage device, the liquid storage device 100c includes a first partition 4 and a second partition 40. The second partition 40 is arranged parallel to the first partition 4. The liquid storage device 100c has a first cavity 103, a second cavity 203 and a third cavity 303. The third cavity 303 is located on one side of the second partition 40, and the first cavity 103 is located on the other side of the second partition 40. The third cavity 303 communicates with the first cavity 103. The liquid storage device 100c also includes a third orifice 104 and a third filter device 50. The third orifice 104 is formed in the first cover portion 2 and communicates with the third cavity 303. The third orifice 104 can serve as another inlet of the liquid storage device. The third filter device 50 is located in the third cavity 303 and can filter water and impurities. Of course, the third filter device 50 may not be included, but may be placed outside the liquid storage device. The above-mentioned two-inlet and one-outlet method is beneficial to meet the multi-flow path requirements of the system.

[0055] See Figure 16 and Figure 17 In this embodiment, the first cover portion 2 includes a mounting portion 24, the opening of which communicates with the third cavity 303; the liquid storage device 100c also includes a first one-way valve assembly 60, which is located within the cavity formed by the mounting portion 24. At least a portion of the first one-way valve assembly 60 allows the working medium to flow into the third cavity 303 from the third orifice 104, but the working medium in the third cavity 303 cannot flow out from the third orifice 104; specifically, see Figure 17The first one-way valve assembly 60 includes a valve seat 601, a valve core assembly 602, a spring 603, a gasket 604, and a limiting member 605. The valve seat 601 is sealed to the side wall of the mounting portion 24. The limiting member 605 is closer to the third orifice 104 than the gasket 604. One end of the spring 603 abuts against the valve seat 601, and the other end of the spring 603 abuts against the gasket 604. The limiting member 605 can restrict the spring 603 from moving along the first one-way valve assembly. Axial disengagement of 60; specifically, the valve core assembly 602 includes a valve stem 6021 and a valve core 6022. The lower end of the valve stem 6021 is limitedly connected to or fixedly disposed with the valve core 6022. The valve stem 6021 passes through a through hole on the valve seat 601. A spring 603, a gasket 604, and a limiting member 605 are sleeved on the outer periphery of the valve stem 6021. In this embodiment, the limiting member 605 is a snap ring. Of course, the limiting member 605 can also be other structures; see Figure 17 The valve seat 601 includes a valve port portion 6010 and a communicating cavity 6011. The communicating cavity 6011 can communicate with the cavity of the valve port portion 6010. At least a portion of the valve core 6022 is located in the cavity formed by the valve port portion 6010. The valve core 6022 and the side wall of the valve port portion 6010 can be sealed together. The opening of the valve port portion 6010 faces the third cavity 303.

[0056] See Figure 16 and Figure 17 When the working medium flows in from the third orifice 104, it flows into the connecting cavity 6011. The working medium in the connecting cavity 6011 applies positive pressure to the upper surface of the valve core 6022. Under the action of positive pressure, the valve core 6022 can move away from the valve port 6010, thereby driving the valve stem 6021, spring 603 and gasket 604 to move axially downward. At this time, the spring 603 will be compressed. When the valve core 6022 moves away from the valve port 6010 to a set distance, the valve port 6010 opens, thereby connecting the cavity of the valve port 6010 with the third cavity 303, so that the working medium can flow into the third cavity 303. In this embodiment, a first one-way valve assembly 60 is provided at the connection between the third orifice 104 and the third cavity 303. This integrates the first one-way valve assembly 60 into the liquid storage device, making the system structure more compact. Alternatively, a second one-way valve assembly can be provided only at the connection between the first orifice 101 and the first cavity 103. The structure of the second one-way valve assembly can be the same as that of the first one-way valve assembly. The second one-way valve assembly allows the working medium to flow from the first orifice 101 into the first cavity 103, but the working medium in the first cavity 103 cannot flow out from the first orifice 101. Alternatively, the first one-way valve assembly can be provided at the connection between the third orifice 104 and the third cavity 303, and the second one-way valve assembly can be provided at the connection between the first orifice 101 and the first cavity 103.

Figure 22 The liquid storage device 100f also includes a baffle 95, which covers the first pipe opening 912. At least part of the baffle 95 is located between the first pipe opening 912 and the first orifice 101. In this embodiment, the baffle 95 is fixedly connected to the first partition 4, and the first orifice 101 and the second orifice 102 are both formed in the first cover part 2. In addition, the liquid storage device 100f in this embodiment may also include a second partition, the structure of which can refer to the liquid storage device in the third embodiment described above.

[0063] See Figure 22 In this embodiment, the liquid storage device 100f further includes a first filter device 5, which can filter moisture in the working medium. Of course, the first filter device 5 can also be used to filter impurities; see [link to previous section]. Figure 23 The first filter device 5 is located between the first connecting part 91 and the first partition 4. The first filter device 5 is located in the first cavity 103. Of course, the first filter device 103 can also be located at the bottom of the first receiving part 10 or other positions.

[0064] See Figure 23 and Figure 24 In this embodiment, the liquid storage device 100f also includes an oil return device 70, which is fixedly connected to the third connecting part 93. The oil return device 70 is disposed relatively close to the lower end face of the first partition 4. The oil return device 70 includes a second filter device 72 and an oil return channel 71.

[0066] The working principle of the liquid storage device in the seventh embodiment will be described in detail below.

[0067] See Figure 22 and Figure 23 When the gas-liquid mixture of refrigerant enters the first chamber 103 from the first orifice 101, the baffle 90 covers the first pipe opening 912, preventing the liquid refrigerant from entering. Simultaneously, due to the difference in specific gravity between the gaseous and liquid media, the liquid refrigerant settles downwards, while the gaseous working medium floats above it. It then enters the first pipe opening 912, flows through the channel within the conduit 90 into the second orifice 102, and finally flows out from the second orifice 102. Regarding the oil return device 70, when the gas-liquid mixture contains oil, because the oil's specific gravity is greater than that of the liquid refrigerant, the oil settles to the bottom of the first receiving portion 10. The oil then passes through the second filter device 72 and flows into the oil return channel 71, then through the oil return channel 71 into the channel within the conduit 90, and finally flows out from the second orifice 102.
