[0010] an elastic gasket, disposed between the sealing plate and the fixing plate; and

[0011] A reset member, one end of which is connected to the sealing plate, and the other end of which is connected to the fixing plate and can drive the sealing plate to move closer to or away from the fixing plate;

[0012] At least two of the through holes sequentially penetrate the sealing plate, the elastic gasket, and the fixing plate.

[0013] In one embodiment of the present application, the reversing assembly further includes an adsorption component which can drive the elastic component to reset or contract so as to make the sealing plate approach or move away from the tube body.

[0014] In one embodiment of the present application, the adsorption member is an electromagnet.

[0015] In one embodiment of the present application, a sealing gasket is provided between the tube body and the sealing plate.

[0016] The present application also discloses a heat exchange system, comprising at least one reversing device as described in any one of the above items, wherein the reversing component has two through holes, namely a first through hole and a second through hole, wherein the end of the first through hole away from the hose is connected to the air outlet of the heat exchanger, and the end of the second through hole away from the hose is connected to the return air outlet of the heat exchanger.

[0020] Figure 2 This is a schematic diagram of the explosion structure of the first embodiment of the present invention. DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention is described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain the present invention and do not constitute a limitation to the present invention.

[0022] like Figure 1 to Figure 2 As shown, in order to achieve the above-mentioned purpose, the present invention proposes a reversing device, including a reversing component 10 with at least two through holes and the same side of the two through holes can be connected to different hoses; and a driving member 20 for driving the reversing component 10, the positions of the two through holes are interchanged so that the end of the through hole away from the hose corresponds to a different tube body 30.

[0023] Specifically, a reversing device includes a reversing assembly 10 and a driving member 20 .

[0024] The driving member 20 adopts a stepping motor or a servo motor commonly used in the prior art, etc. Since they are prior art, they will not be described in detail here.

[0025] At least two through holes are provided on the reversing assembly 10 .

[0026] When the number of through holes is two, the two through holes are respectively a first through hole and a second through hole, the first through hole and the second through hole are arranged in parallel, and different hoses are connected to the same side of the first through hole and the second through hole, the first through hole is connected to the first hose 40, and the second through hole is connected to the second hose 50. The first through hole and the first hose 40 are connected in a detachable manner, such as screw connection, bolt connection, etc. The first through hole and the first hose 40 are connected in a detachable manner, which can facilitate the installation and disassembly between the first through hole and the first hose 40, and facilitate later maintenance. Of course, according to the design requirements, the first through hole and the first hose 40 can also be connected in a fixed connection manner. For example, welding, etc. The fixed connection can improve the connection strength between the first through hole and the first hose 40 and ensure the stability of the first hose 40 when working.

[0027] The connection mode between the second hose 50 and the second through hole is the same as the connection mode between the first hose 40 and the first through hole, and has the same advantages, which will not be described in detail here.

[0028] It is conceivable that the first through hole can be connected to a plurality of different hoses, and the second through hole can also be connected to a plurality of different hoses, so as to realize the supply and return of air to different areas.

[0029] When the number of through holes is three, they are the third through hole, the fourth through hole, and the fifth through hole. The third through hole, the fourth through hole, and the fifth through hole are evenly distributed, and different hoses are connected to the same side of the third through hole, the fourth through hole, and the fifth through hole. The hose connected to the third through hole is the third hose, the hose connected to the fourth through hole is the fourth hose, and the hose connected to the fifth through hole is the fifth hose.

[0030] The third through hole, the fourth through hole, and the fifth through hole are connected to the third hose, the fourth hose, and the fifth hose in the same manner and have the same advantages. They can be connected in a fixed manner or in a detachable manner, and the effects are the same as above, which will not be described in detail here.

[0031] The driving member 20 is connected to the reversing assembly 10, and can drive at least two through holes on the reversing assembly 10 to exchange positions with each other, so that the end of the through hole away from the hose can correspond to a different tube body 30. The tube body 30 can be a hose, or a hard metal tube or a plastic tube.

[0032] By adopting the above technical solution, the reversing assembly 10 with two through holes is driven by a motor, so that the end of the through hole away from the hose corresponds to a different tube body 30, and the two tube bodies 30 can be switched to be connected to different hoses respectively. Without removing the pipeline, the switching between pipelines is automatically realized. The structure is simple and easy to implement.

[0033] In one embodiment of the present application, the reversing assembly 10 includes:

[0034] The sealing plate 11 can be in contact with the tube body 30;

[0035] A fixing plate 13, disposed on a side of the sealing plate 11 away from the tube body 30 and used for connecting the hose;

[0036] An elastic gasket 12 is provided between the sealing plate 11 and the fixing plate 13; and

[0037] A reset member 14, one end of which is connected to the sealing plate 11, and the other end of which is connected to the fixing plate 13, and can drive the sealing plate 11 to move closer to or away from the fixing plate 13;

[0038] At least two of the through holes sequentially penetrate the sealing plate 11 , the elastic gasket 12 , and the fixing plate 13 .

[0039] Specifically, the sealing plate 11 is made of metal material, such as aluminum alloy material, alloy steel material, etc. The sealing plate 11 made of metal material has the advantages of strong support ability and wear resistance. Of course, according to the design requirements, the sealing plate 11 can also be made of plastic material. The sealing plate 11 made of plastic material has the advantages of light weight, low cost, easy production, etc.

[0040] The sealing plate 11 is circular in shape, which saves materials and facilitates the installation and fixing of the sealing plate 11. The square plate can abut against the tube body 30.

[0041] The fixing plate 13 is made of metal material, such as aluminum alloy material, alloy steel material, etc. The fixing plate 13 made of metal material has the advantages of strong supporting ability and wear resistance. Of course, according to the design requirements, the fixing plate 13 can also be made of plastic material. The fixing plate 13 made of plastic material has the advantages of light weight, low cost, easy production, etc. The fixing plate 13 is used to connect the hose.

[0042] The sealing plate 11 and the fixing plate 13 are arranged opposite to each other and correspond to each other.

[0043] The elastic gasket 12 is arranged between the sealing plate 11 and the fixing plate 13. The elastic gasket 12 can be deformed under the action of pressure. The elastic gasket 12 is made of latex material.

[0044] The reset member 14 may be a reset spring, one end of which is connected to the sealing plate 11 , and the other end of which is connected to the fixing plate 13 . The reset member 14 may drive the sealing plate 11 to move closer to or away from the fixing plate 13 .

[0045] The two through holes sequentially penetrate the sealing plate 11, the elastic gasket 12, and the fixing plate 13. By providing the elastic gasket 12, when the sealing plate 11 approaches or moves away from the fixing plate 13, the wind field between the two through holes will not be interlaced, thus ensuring the independence of the two through holes.

[0046] By adopting the above technical solution, by setting the sealing plate 11, the fixing plate 13, the elastic gasket 12, and the reset member 14, the sealing plate 11 can be moved close to or away from the fixing plate 13. With this design, before the driving member 20 drives the reversing assembly 10 to rotate, the reset member 14 first disengages the contact between the sealing plate 11 and the tube body 30, and then rotates to avoid friction between the sealing plate 11 and the tube body 30. It is ensured that the reversing assembly 10 can stably switch the positions of the two through holes on the reversing assembly 10.

[0047] In an embodiment of the present application, the reversing assembly 10 further includes an adsorption member capable of driving the elastic member to reset or contract so as to make the sealing plate 11 approach or move away from the tube body 30 .

[0048] Specifically, the reversing assembly 10 further includes an adsorption member, which can drive the elastic member to reset or contract. The elastic member is a compression spring, and its contracted state indicates that the spring is in a compressed state, and at this time, the sealing plate 11 is close to the fixed plate 13. When the elastic member is in a reset state, the compression spring is in a fully open state, and at this time, the sealing plate 11 is away from the fixed plate 13. In the reset state of the compression spring, the compression spring will press the sealing plate 11 against the tube body 30, thereby realizing the connection between the through hole and the tube body 30.

[0049] The adsorption member can be an electromagnet, a permanent magnet, etc.

[0050] When the adsorption member is a permanent magnet, a driving device needs to be provided to drive the permanent magnet to approach or move away from the fixing plate 13, thereby driving the compression spring to contract or reset.

[0051] The above technical solution has a simple structure and is easy to implement.

[0052] In one embodiment of the present application, the adsorption member is an electromagnet.

[0053] Specifically, the adsorption member is set as an electromagnet, and the magnetic force is generated by supplying power to the electromagnet to drive the compression spring. No other components are required, and the control and installation are convenient.

[0054] In one embodiment of the present application, a sealing gasket is provided between the tube body 30 and the sealing plate 11 .

[0055] Specifically, a sealing gasket is provided between the tube body 30 and the sealing plate 11. The sealing gasket is made of plastic material. The sealing member made of plastic material has a certain deformation amount, which can achieve sealing between the tube body 30 and the sealing plate 11. It can avoid air leakage between the tube body 30 and the through hole.

[0056] The present application also discloses a heat exchange system, comprising at least one reversing device as described in any one of the above items, wherein the reversing component 10 has two through holes, namely a first through hole and a second through hole, wherein the end of the first through hole away from the hose is connected to the air outlet of the heat exchanger, and the end of the second through hole away from the hose is connected to the return air outlet of the heat exchanger.

[0057] Specifically, the heat exchange system may be an air conditioning refrigeration system, when a reversing device is installed on the heat exchange system.

[0058] The heat exchange component has two through holes, namely the first through hole and the second through hole. The end of the first through hole away from the hose is connected to the air outlet of the heat exchanger, and the end of the second through hole away from the hose is connected to the return air outlet of the heat exchanger, thereby realizing a complete closed-circuit cycle, with a simple structure and easy implementation. The heat exchanger in this application can be an indoor unit of an air conditioner, or of course, an outdoor unit of an air conditioner.

[0059] When two reversing devices are installed on the heat exchange system. The two reversing devices are respectively the first reversing device and the second reversing device. The number of through holes connected to the first reversing device is two, namely the first through hole and the second through hole. The end of the first through hole away from the hose is connected to the air outlet of the heat exchanger, and the end of the second through hole away from the hose is connected to the return air outlet of the heat exchanger; the number of through holes connected to the second reversing device is two, namely the first through hole and the second through hole. The end of the first through hole away from the hose is connected to the air outlet of the heat exchanger, and the end of the second through hole away from the hose is connected to the return air outlet of the heat exchanger. Thus, one heat exchange system corresponds to multiple different supply and return air ducts, and switching between different supply and return air ducts is realized. The structure is simple and easy to implement.

[0060] In the process of realizing pipeline switching, the adsorption component first generates adsorption force, so that the sealing plate 11 is close to the fixed plate 13. At this time, the sealing plate 11 is out of contact with the pipeline. After the driving component drives the sealing plate 11 to rotate, the adsorption component loses the adsorption force. The sealing plate 11 is driven away from the fixed plate 13 by the resetting component 14, so that the sealing plate 11 abuts against the pipe body, thereby realizing the resetting of the sealing plate 11.

[0061] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
