[0024] By adopting the above technical solution, when the drain chassis body 4 needs to be dismantled for inspection and maintenance, the pressing rod 53 is pressed, and the pressing rod 53 drives the clamping slider 54 to move the compressed clamping spring 55, so that the clamping block 52 is disengaged from the clamping hole, and then the limit fixing plate 51 can be removed, and then the drain chassis body 4 can be taken out of the positioning seat for inspection and maintenance, so that when the device is in use, it is convenient to remove the drain chassis body 4 from the air source heat pump body 1 when the components inside the drain chassis body 4 are damaged, thereby improving the practicality of use.

[0025] Specifically, a stabilizing slide bar 56 is slidably provided at one end of the pressing rod 53, and a guide sliding opening is provided at one end of the clamping block 52.

[0026] By adopting the above technical solution, the stabilizing slide bar 56 facilitates the stable movement of the pressing rod 53, and the guide slide mouth facilitates the downward movement of the clamping block 52 when the limiting fixing plate 51 is installed.

[0027] When this embodiment is in use: when the drainage chassis body 4 needs to be dismantled for inspection and maintenance, the pressing rod 53 is pressed, and the pressing rod 53 drives the clamping slider 54 to move the compressed clamping spring 55, so that the clamping block 52 is disengaged from the clamping hole, and then the limiting fixing plate 51 can be removed, and then the drainage chassis body 4 can be taken out of the positioning seat for inspection and maintenance, so that when the device is in use, it is convenient to remove the drainage chassis body 4 from the air source heat pump body 1 when the components inside the drainage chassis body 4 are damaged, thereby improving the practicality of use.

[0028] Example 2

[0029] The difference between this embodiment and embodiment 1 is that: specifically, the clamping assembly 7 includes a clamping seat 71, an insert block 72, a bidirectional threaded screw 73, a turning handle 74, a moving block 75 and a clamping plate 76, wherein a clamping seat 71 is provided at one end above the filter device 6, an insert block 72 is inserted at one side of the clamping seat 71, a bidirectional threaded screw 73 is provided inside the clamping seat 71, a turning handle 74 is provided at one end of the bidirectional threaded screw 73, the surface of the bidirectional threaded screw 73 is symmetrical and is threadedly connected to a moving block 75, and a clamping plate 76 is provided at one end of the moving block 75.

[0030] By adopting the above technical solution, when the detection device 8 needs to be dismantled for maintenance, the screw 78 is rotated to make the rubber fastening plate 77 move away from the turning handle 74, and then the turning handle 74 is rotated. The turning handle 74 drives the bidirectional threaded screw 73 to rotate, and the rotation of the bidirectional threaded screw 73 drives the moving block 75 to move, thereby driving the clamping plate 76 to move away from the plug-in block 72, so that the detection device 8 can be dismantled, so that when the device is in use, it is convenient to remove the detection device 8, maintain or replace it, thereby improving the practicality of use.

[0031] Specifically, a rubber fastening plate 77 is provided at the turning rod of the turning handle 74 , and a screw rod 78 is provided at one end of the rubber fastening plate 77 .

[0032] By adopting the above technical solution, the screw rod 78 and the rubber fastening plate 77 facilitate fastening the turning handle 74 .

[0035] When the present embodiment is in use, when the detection device 8 needs to be removed for maintenance, the screw rod 78 is rotated to move the rubber fastening plate 77 away from the turning handle 74, and then the turning handle 74 is rotated. The turning handle 74 drives the bidirectional threaded screw 73 to rotate, and the rotation of the bidirectional threaded screw 73 drives the moving block 75 to move, thereby driving the clamping plate 76 to move away from the plug-in block 72, so that the detection device 8 can be removed, making it convenient to remove the detection device 8 for maintenance or replacement when the device is in use, thereby improving the practicality of use.

[0036] The structure and use principle of the air source heat pump body 1, evaporator 3, drainage chassis body 4, filter device 6 and detection device 8 in the utility model have been disclosed in an air source heat pump drainage chassis disclosed in Chinese patent application No. 202320185355.7. Its working principle is that an evaporator 3 is arranged inside the heat source pump main unit, and a drainage chassis body 4 is arranged below the evaporator 3, wherein the drainage chassis body 4 is used to collect defrost water generated by the evaporator 3, and a filter device 6 is detachably installed inside the heat source pump main unit, and the filter device 6 is located above the drainage chassis body 4. Before the defrost water falls into the drainage chassis body 4, impurities will be filtered through the filter device 6, effectively avoiding the situation where impurities block the drain outlet, and a detection device 8 is fixedly installed inside the heat source pump main unit, and the detection device 8 is located above the filter device 6. The liquid level height on the filter device 6 is detected by an infrared sensor, which effectively avoids the phenomenon that when the filter device 6 is blocked by impurities, the defrost water continues to accumulate and affects the operation of the evaporator 3.

[0037] Working principle and use process of the utility model: when the utility model is in use, a drainage pan body 4 is arranged below the evaporator 3, wherein the drainage pan body 4 is used to collect defrost water generated by the evaporator 3, and a filter device 6 is detachably installed inside the heat source pump main unit, and the filter device 6 is located above the drainage pan body 4. Before the defrost water falls into the drainage pan body 4, impurities will be filtered through the filter device 6, which effectively avoids the situation where the impurities block the drain port. The liquid level on the filter device 6 can be detected by the detection device 8. When the drainage pan body 4 needs to be dismantled for inspection and maintenance, the inspection door 2 is opened, and then the disassembly assembly 5 is removed, and then the drain pipe is unscrewed, so that the drainage pan body 4 can be taken out. When the detection device 8 needs to be removed, it can be removed by the clamping assembly 7. When the disassembly assembly 5 is in use, when the drainage pan body 4 needs to be dismantled for inspection and maintenance, the pressing rod 53 is pressed, and the pressing rod 5 3 drives the clamping slider 54 to move and compress the clamping spring 55, so that the clamping block 52 disengages from the clamping hole, and then the limiting fixing plate 51 can be removed, and then the drainage chassis body 4 can be taken out from the positioning seat for inspection and maintenance, so that when the device is in use, it is convenient to remove the drainage chassis body 4 from the air source heat pump body 1 when the components inside the drainage chassis body 4 are damaged, thereby improving the practicality of use. When the clamping assembly 7 is in use, when it is necessary to remove the detection device 8 for maintenance, the screw 78 is rotated to make the rubber fastening plate 77 away from the turning handle 74, and then the turning handle 74 is rotated. The turning handle 74 drives the two-way threaded screw rod 73 to rotate, and the rotation of the two-way threaded screw rod 73 drives the moving block 75 to move, thereby driving the clamping plate 76 to move, making it away from the plug-in block 72, so that the detection device 8 can be removed, so that when the device is in use, the detection device 8 is convenient to remove, maintain or replace it, thereby improving the practicality of use.
