Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features.

[0026] In this application, the term "exemplary" is used to mean "serving as an example, illustration, or illustration." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The term "and / or" includes any and all combinations of one or more of the associated listed items.

[0027] This application provides an air conditioning pressure protection device, such as... Figures 1-4 As shown, the air conditioner includes a pressure relief mechanism, a three-way connector 120, and an alignment and mounting mechanism. The pressure relief mechanism includes a housing 110 with an air inlet 112. The three-way connector 120 has a first interface 121, a second interface, and a third interface 122. The first interface 121 is used to connect to the air inlet 112, and the second interface is used to connect to the exhaust pipe 210 of the compressor 200. The housing 110 is connected to the alignment and mounting mechanism, which can drive the pressure relief mechanism to move along a first direction A so that the air inlet 112 can be inserted into or separated from the first interface 121.

[0028] The air conditioning pressure protection device provided in this application embodiment can drive the pressure relief mechanism to move along the first direction A, so that the air inlet 112 can be inserted into or separated from the first interface 121. Therefore, when the pressure relief mechanism needs to be installed, the pressure relief mechanism can be driven to move along the first direction A by controlling the alignment and installation mechanism, so that the air inlet 112 of the housing 110 of the pressure relief mechanism can be aligned and inserted into the first interface 121 of the three-way connector 120, which facilitates the installation of the pressure relief mechanism and the three-way connector 120. When the pressure relief mechanism needs to be disassembled, the pressure relief mechanism can be driven to move along the first direction A by controlling the alignment and installation mechanism, so that the air inlet 112 of the housing 110 of the pressure relief mechanism can be separated from the first interface 121 of the three-way connector 120, which facilitates the disassembly of the pressure relief mechanism.

[0029] In some embodiments of this application, the alignment and mounting mechanism includes a first mounting plate 181 and a second mounting plate 182. The second mounting plate 182 is connected to the first mounting plate 181 and can drive the first mounting plate 181 to move along a first direction A. The housing 110 is disposed on the first mounting plate 181. This arrangement enables the connection between the housing 110 and the alignment and mounting mechanism, while the alignment and mounting mechanism can drive the pressure relief mechanism to move along the first direction A.

[0030] Optionally, the first mounting plate 181 is provided with a groove that matches the housing 110, and the housing 110 is embedded in the groove, thereby enabling the housing 110 of the pressure relief mechanism to be mounted on the first mounting plate 181.

[0031] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the alignment and mounting mechanism also includes a threaded rod 190, which is rotatably mounted on the air conditioner housing 300 about an axis in the first direction A. A threaded hole 183 is provided on the second mounting plate 182, and the threaded rod 190 passes through and is threaded into the threaded hole 183. By providing the threaded rod 190 and the threaded hole 183, the second mounting plate 182 can be rotated to move the first mounting plate 181 and the housing 110 along the first direction A, facilitating the alignment and insertion or separation of the air inlet 112 of the housing 110 with the tee connector 120.

[0032] Optional, combined Figure 1 , Figure 2 and Figure 4 As shown, the air conditioner housing 300 is provided with a positioning block 310 having a positioning hole, and one end of the threaded rod 190 is provided with a positioning part 191, which is rotatably inserted into the positioning hole around the axis of the first direction A. By providing the positioning block 310 and the positioning part 191, the threaded rod 190 can be rotatably mounted on the air conditioner housing 300 around the axis of the first direction A.

[0033] Optional, such as Figure 2 As shown, the alignment and mounting mechanism also includes a limiting block 184, which is fixed to one end of the first mounting plate 181. The second mounting plate 182 is provided with a sliding groove 185 extending along the second direction B, and the limiting block 184 is slidably engaged in the sliding groove 185. By setting the limiting block 184 and the sliding groove 185, it is convenient to quickly assemble and disassemble the first mounting plate 181 and the second mounting plate 182, which helps to improve the efficiency of assembly and disassembly.

[0034] In some embodiments of this application, a chamber 111 is formed inside the housing 110, and the housing 110 is provided with a pressure relief port 113. The pressure relief port 113 and the air inlet 112 are both connected to the chamber 111. The pressure relief mechanism also includes a piston 130, which is slidably disposed in the chamber 111 along a first direction A to open and close the pressure relief port 113.

[0035] Specifically, during the sliding process, the piston 130 has a closed position with the pressure relief port 113 closed and an open position with the pressure relief port 113 open. When the pressure in the chamber 111 does not exceed the preset pressure value, the piston 130 is in the closed position, and the pressure relief port 113 is closed. When the pressure in the chamber 111 exceeds the preset pressure value, the piston 130 is in the open position, and the pressure relief port 113 is open.

[0036] The air conditioning pressure protection device provided in this application embodiment is configured with a piston 130 that can be slidably disposed in the chamber 111 along the first direction A to open and close the pressure relief port 113. When the discharge pressure of the compressor 200 is too high (i.e. the discharge pressure exceeds the preset pressure value), the high-pressure gas discharged by the compressor 200 will enter the chamber 111 of the housing 110 through the air inlet 112 when passing through the three-way connector 120, causing the air pressure in the chamber 111 to increase. The increased air pressure pushes the piston 130 to slide along the first direction A to the position where the pressure relief port 113 is opened (i.e., the open position), so that the high-pressure gas is discharged from the pressure relief port 113 to the outside. This achieves automatic pressure relief when the discharge pressure of the compressor 200 is too high, so as to ensure the stability of the air conditioning operation.

[0037] Optional, combined Figure 2 and Figure 4 As shown, the pressure relief mechanism also includes a pneumatic pipe 140 and a push rod 150. One end of the pneumatic pipe 140 is closed and the other end is connected to the chamber 111. One end of the push rod 150 is connected to the piston 130 and the other end extends into the pneumatic pipe 140. The end of the push rod 150 away from the piston 130 is provided with an elastic part 151 that can extend and retract along the first direction A. Specifically, under normal circumstances, piston 130 is in the closed position with the pressure relief port 113 closed, and elastic part 151 is in a free state. When the discharge pressure of compressor 200 is too high, the high-pressure gas discharged by compressor 200 will enter the chamber 111 of housing 110 through the air inlet 112 when passing through the three-way connector 120, causing the air pressure in chamber 111 to increase. The increased air pressure will push piston 130 to move along the first direction A to the open position and compress elastic part 151 to open pressure relief port 113, so that high-pressure gas is discharged from pressure relief port 113 to the outside, realizing automatic pressure relief. After the pressure relief is completed, piston 130 slides along the first direction A to the closed position under the elastic force of elastic part 151 to close pressure relief port 113.

[0038] In some embodiments of this application, such asFigure 1 and Figure 2 As shown, the air conditioning pressure protection device also includes a pressure tank 160 and an air exchange pipe 161. One end of the air exchange pipe 161 is connected to the pressure relief port 113, and the other end of the air exchange pipe 161 is connected to the pressure tank 160. By setting up the pressure tank 160 and the air exchange pipe 161, the air pressure discharged from the pressure relief port 113 can be collected in the pressure tank 160 for reuse, preventing the waste of air pressure and reducing the cost of air pressure.

[0039] Optionally, the air conditioning pressure protection device also includes a pressure-replenishing pipe 170. The side wall of the housing 110 is also provided with a pressure-replenishing port 114 communicating with the chamber 111. One end of the pressure-replenishing pipe 170 is connected to the pressure-replenishing port 114, and the other end of the pressure-replenishing pipe 170 is used to connect to the exhaust pipe 210 of the compressor 200. A one-way valve is provided on the pressure-replenishing pipe 170. By setting up the pressure-replenishing pipe 170 and the pressure-replenishing port, pressure can be replenished within the chamber 111 to maintain pressure balance within the chamber 111.

[0040] This application also provides an air conditioner, such as... Figure 3 and Figure 4 As shown, the air conditioner includes a compressor 200 and an air conditioning pressure protection device. The specific structure of the air conditioning pressure protection device is as described in the above embodiment. The compressor 200 is provided with an exhaust pipe 210, which is connected to the second interface of the three-way connector 120 in the air conditioning pressure protection device. Since this air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0041] Optionally, the air conditioner also includes a housing 300 and a heat dissipation mechanism, such as... Figure 3 As shown, the heat dissipation mechanism includes a fan 410 and a heat insulation plate 420. The heat insulation plate 420 divides the interior of the casing 300 into a first space 301 and a second space 302. The fan 410 is located in the first space 301, while the compressor 200 and the air conditioning pressure protection device are both located in the second space 302. This arrangement separates the compressor 200 and the air conditioning pressure protection device from the heat in the first space 301, preventing heat from being transferred to the compressor 200 and the air conditioning pressure protection device, thus reducing the adverse effects of heat on them.

[0042] In some embodiments, the heat dissipation mechanism further includes a plurality of heat-conducting elements 430, which are spaced apart on the inner sidewall of the housing 300. By providing the heat-conducting elements 430, heat inside the housing 300 can be absorbed, thereby improving heat dissipation efficiency.

[0043] Optionally, the heat-conducting element 430 can be an L-shaped heat-conducting sheet, with multiple L-shaped heat-conducting sheets spaced apart along the first direction A. Alternatively, the heat-conducting element 430 can also be other shapes, as long as it can achieve heat absorption; the specific design can be determined according to actual needs.

[0044] Optional, such as Figure 3 As shown, the heat dissipation mechanism also includes a positioning plate 440, one end of which is connected to the housing of the fan 410, and the other end of which is connected to the housing 300. By setting the positioning plate 440 to connect the housing 300 and the housing of the fan 410, the fan 410 can be more stably installed inside the housing 300.
