[0032] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0033] See also Figure 1 and Figure 2, a hydraulic module 100 provided in an embodiment of the present application, the hydraulic module 100 can include a box body 10 and an expansion tank 20, an installation cavity 101 is formed inside the box body 10, and an inspection port 102 communicating with the installation cavity 101 is provided on the outer side of the box body 10, the expansion tank 20 can be arranged in the installation cavity 101, and the expansion tank 20 has an inflation port 201, and the inflation port 201 can be arranged corresponding to the inspection port 102.

[0034] Optionally, the shape of the box body 10 can be cylindrical, cubic, etc. The specific shape of the box body 10 is not limited and can be set according to the actual space for installing the hydraulic module 100. In the embodiment of the present application, the box body 10 is in a cubic shape as an example for explanation. The expansion tank 20 is set in the installation cavity 101, and the inflation port 201 of the expansion tank 20 can be set corresponding to the inspection port 102 on the box body 10, so that the staff can observe the inflation port 201 through the inspection port 102.

[0035] Optionally, the shape of the inspection port 102 can be circular, square, polygonal, etc., and the specific shape of the inspection port 102 is not limited. Preferably, the inspection port 102 is circular so that the inspection port 102 can adapt to the pipe on the detection equipment and facilitate the insertion of the pipe into the inspection port 102.

[0036] When it is necessary to detect the pressure of the expansion tank 20 or to inflate the expansion tank 20, the detection equipment can be directly connected to the inflation port 201 on the expansion tank 20 through the inspection port 102 to detect the pressure of the expansion tank 20, and the external gas source can also be connected to the inflation port 201 on the expansion tank 20 through the inspection port 102 to restore the pressure of the expansion tank 20 to the default value set at the factory. Therefore, the staff can directly perform detection operations or inflation operations on the expansion tank 20 through the inspection port 102 without removing the panel on the hydraulic module 100, and can conveniently detect or adjust the pressure of the expansion tank 20.

[0037] See also Figure 1 and Figure 2 In some embodiments, the box body 10 may have a top plate 11 , the top plate 11 may be provided with an inspection port 102 , and one end of the expansion tank 20 provided with the inflation port 201 may be disposed close to the top plate 11 .

[0038] Optionally, the box body 10 is in a cubic shape, and the box body 10 includes a bottom plate, four side plates and a top plate 11. The bottom plate, the side plates and the top plate are all square plates. The four side plates can be connected to the four sides of the bottom plate respectively, and the four side plates are also connected in sequence. The top plate 11 is arranged opposite to the bottom plate, and the top plate 11 is connected to multiple side plates, so that the bottom plate, the four side plates and the top plate 11 can form an installation cavity 101.

[0039] The expansion tank 20 can be fixed in the installation cavity 101, and the expansion tank 20 is located at the upper part of the installation cavity 101. The expansion tank 20 has an inflation port 201 at one end thereof arranged toward the top plate 11, so that the inflation port 201 can be arranged adjacent to the inspection port 102 on the top plate 11. After the staff passes the pipeline through the inspection port 102, the pipeline can be conveniently connected to the inflation port 201, which further facilitates the detection or adjustment of the pressure of the expansion tank 20.

[0040] See also Figure 1 and Figure 2 In some embodiments, the hydraulic module 100 can further include a cover plate 30 , which can be movably disposed on the outer side of the box body 10 , and the cover plate 30 can be used to open or close the inspection port 102 .

[0041] Optionally, the cover plate 30 can be slidably mounted on the outer side of the box body 10 , so that the cover plate 30 can slide along the outer side of the box body 10 to open the inspection opening 102 , or slide along the outer side of the box body 10 to close the inspection opening 102 .

[0042] When it is necessary to detect the pressure of the expansion tank 20 or to inflate the expansion tank 20 , the cover plate 30 can be slid to open the inspection port 102 so that the inflation port 201 is exposed from the inspection port 102 , and the staff can connect the pipeline to the inflation port 201 through the inspection port 102 .

[0043] When the pressure test of the expansion tank 20 is completed, or the inflation of the expansion tank 20 is completed, the cover plate 30 can be slid to close the inspection port 102 so that the cover plate 30 can prevent dust, sewage and other debris from entering the box body 10 through the inspection port 102.

[0044] In some other embodiments, the cover 30 can be rotatably installed on the outer surface of the box body 10, so that the cover 30 can be rotated to open the inspection port 102, or rotated to close the inspection port 102. The role of the cover 30 is the same as described above and will not be repeated here.

[0045] See also Figures 1 to 3 In some embodiments, the hydraulic module 100 can include a mounting base 40, which can be fixed to the outer surface of the box body 10, and the mounting base 40 can be arranged adjacent to the inspection port 102, and the cover plate 30 can be rotatably mounted on the mounting base 40, so that the cover plate 30 can be switched between an open position and a closed position.

[0046] When the cover 30 is rotated to the open position, the cover 30 can be set at an angle with the outer side surface of the box body 10, thereby opening the inspection port 102. When the cover 30 is rotated to the closed position, the cover 30 can be set in contact with the outer side surface of the box body 10, thereby closing the inspection port 102.

[0047] Optionally, the mounting base 40 can be fixed to the top plate 11 by a threaded connection, and the mounting base 40 has a rotating shaft, and the cover plate 30 can be rotatably mounted on the rotating shaft, so that the cover plate 30 can be rotated relative to the mounting base 40, and the cover plate 30 can be rotated in a direction close to the inspection port 102 until the cover plate 30 is in contact with the outer side surface of the box body 10 and covers the inspection port 102, so that the cover plate 30 can close the inspection port 102, and the cover plate 30 can also be rotated in a direction away from the inspection port 102 until the cover plate 30 is set at an angle to the outer side surface of the box body 10, so that the cover plate 30 opens the inspection port 102, and the inflation port 201 can be exposed from the inspection port 102. Therefore, the inspection port 102 can be easily opened or closed by rotating the cover plate 30.

[0048] Optionally, the shape of the cover 30 can be a hood-like structure. When the cover 30 is in the closed position, the cover 30 can cover the inspection port 102, which can increase the sealing performance when the cover 30 closes the inspection port 102 and prevent dust from entering the inspection port 102.

[0049] Optionally, the edge of the cover 30 can have a flange. When the cover 30 is in the closed position, the flange on the cover 30 can fit together with the top plate 11, which can further increase the sealing performance of the cover 30 when closing the inspection port 102. The flange can also increase the structural strength of the cover 30.

[0050] See also Figure 1 and Figure 2 In some embodiments, the hydraulic module 100 can further include a limiter 50, which can be disposed between the mounting seat 40 and the cover plate 30, and the limiter 50 can be used to limit the rotation angle of the cover plate 30 so that the cover plate 30 can rotate between an open position and a closed position.

[0051] Optionally, the limit member 50 can be connected to the mounting seat 40, and the limit member 50 partially protrudes between the mounting seat 40 and the cover plate 30. When the cover plate 30 rotates toward the mounting seat 40, the cover plate 30 will gradually approach the protruding portion of the limit member 50. When the cover plate 30 is rotated to the open position, the cover plate 30 will contact the limit member 50, so that the cover plate 30 can no longer continue to rotate toward the mounting seat 40, so that the limit member 50 will restrict the cover plate 30 to the open position, and at this time the limit member 50 can also be connected to the cover plate 30, so that the cover plate 30 is fixed in the open position, which can facilitate the rotation of the cover plate 30 between the open position and the closed position.

[0052] Optionally, the limiting member 50 may be elastic. When the cover 30 is rotated to the open position, the contact between the cover 30 and the limiting member 50 is soft contact, which can reduce damage to the cover 30 .

[0053] See also Figures 4 to 6In some embodiments, the hydraulic module 100 can further include an inflation tube 60, which can be inserted into the inspection port 102, and the first end of the inflation tube 60 can extend to communicate with the inflation port 201, and the second end of the inflation tube 60 can be located outside the box body 10, and the first end and the second end of the inflation tube 60 are opposite ends.

[0054] Optionally, the inflation tube 60 can be a round tube, and the diameter of the inflation tube 60 is smaller than the diameter of the inspection port 102, so that the inflation tube 60 can be easily inserted into the inspection port 102, and the end of the inflation tube 60 located inside the box body 10 is the first end, the first end of the inflation tube 60 can be connected to the inflation port 201 of the expansion tank 20, and the end of the inflation tube 60 located outside the box body 10 is the second end.

[0055] The second end of the inflation tube 60 can be connected to a detection device, thereby connecting the detection device to the expansion tank 20 through the inflation tube 60, which can further facilitate the detection of the pressure in the expansion tank 20. The second end of the inflation tube 60 can also be connected to an external air source, thereby connecting the external air source to the expansion tank 20 through the inflation tube 60, which can further facilitate the inflation of the expansion tank 20 and thus adjust the pressure in the expansion tank 20.

[0056] See also Figure 4 and Figure 5 In some embodiments, the hydraulic module 100 can further include an interface portion 70 , which can be connected to the second end of the inflation tube 60 , and the interface portion 70 can be used to communicate with an external air source.

[0057] Optionally, the interface part 70 can be directly connected to one end of the inflation tube 60 located outside the box body 10, so that the inflation tube 60 can be connected to an external gas source through the interface part 70. The inflation tube 60 is a hose and the interface part 70 is a metal joint. The inflation tube 60 can be conveniently connected to an external gas source through the interface part 70.

[0058] See also Figures 4 to 6 In some embodiments, the inflation tube 60 can be movably inserted into the inspection port 102 , and the second end of the inflation tube 60 can be selectively retracted into the interior of the box body 10 , or extended to the outside of the box body 10 .

[0059] Optionally, the inflation tube 60 can be a hose with adjustable length, for example, the inflation tube 60 is a telescopic tube, a bellows, etc., and the length of the inflation tube 60 can be adjusted according to actual usage.

[0060] To be more clear, when it is necessary to detect the pressure of the expansion tank 20 or to inflate the expansion tank 20, the second end of the inflation tube 60 can be extended to the outside of the box body 10, and the length of the inflation tube 60 can be extended to facilitate the connection of the inflation tube 60 with external equipment. After adjusting the pressure in the expansion tank 20, the length of the inflation tube 60 can be shortened, and the second end of the inflation tube 60 can be retracted into the inside of the box body 10, that is, the inflation tube 60 is retracted into the box body 10, and the cover plate 30 is closed to close the inspection port 102, which can facilitate the retraction of the inflation tube 60.

[0061] Therefore, when the inflation tube 60 is needed, the inflation tube 60 can be directly drawn out from the interior of the box body 10 . After using the inflation tube 60 , it only needs to be retracted into the box body 10 , which is very convenient to use.

[0062] See also Figure 4 and Figure 5 In some embodiments, the hydraulic module 100 can further include a protective cover 80 , which can be disposed at the inspection port 102 , and the protective cover 80 is provided with a plurality of soft bars 801 , which extend to the inspection port 102 .

[0063] Optionally, the protective cover 80 can be arranged in the inspection port 102, and the protective cover 80 can be arranged along the inner wall of the inspection port 102, so that the multiple soft strips 801 on the protective cover 80 can extend into the inspection port 102, and the multiple soft strips 801 can block the inspection port 102, thereby preventing dust, sewage, insects and other debris from entering the interior of the box body 10, and when the expansion tank 20 needs to be operated, the staff can easily push aside the soft strips 801, and the soft strips 801 will not hinder the staff.

[0064] See also Figure 2 In some embodiments, the axis of the inspection port 102 can be arranged to intersect with the plane where the inflation port 201 is located.

[0065] Optionally, the axis of the inspection port 102 can be arranged to intersect with the plane where the inflation port 201 is located, so that the plane where the inspection port 102 is located is arranged opposite to the plane where the inflation port 201 is located. When the inflation tube 60 passes through the inspection port 102, the inflation tube 60 can extend into the box body 10 along the axial direction of the inspection port 102 and can be smoothly connected to the inflation port 201.

[0066] Preferably, the central axis of the inspection port 102 is collinear with the center line of the inflation port 201 , so that the inspection port 102 and the inflation port 201 are arranged opposite each other, which can further facilitate the connection between the inflation tube 60 and the inflation port 201 .

[0067] An embodiment of the present application further provides a heat pump system, comprising an outdoor unit, a pipeline, and a hydraulic module 100 as described above, wherein the outdoor unit is connected to the hydraulic module 100 via the pipeline.

[0068] The beneficial effects of the heat pump system in this application are the same as those of the hydraulic module 100 in this application, and will not be repeated here.
