DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. The described embodiments are only some of the embodiments of the present application, not all the embodiments. EMBODIMENT

[0025] Please refer to Figures 1-5 The utility model discloses a return air duct leakage detection device of an air conditioner, including air pump 1, the output of air pump 1 is communicated with inflation pipe 2, and the one end of inflation pipe 2 is provided with connecting head 3;Connecting head 3 one side is provided with leakage detection subassembly, and leakage detection subassembly includes detection sleeve 4, and detection sleeve 4 sets up in connecting head 3 one side, and detection sleeve 4 both sides are fixedly connected with connecting block 5, and the inner chamber both sides of connecting head 3 are movably connected with rotating rod 6, and rotating rod 6 surface is fixedly connected with right-angled swing block 7, and right-angled swing block 7 one side is fixedly connected with first spring 13 one end, and right-angled swing block 7 one side is fixedly connected with arc-shaped clamp 8;Connecting head 3 inner chamber is provided with sealing assembly, and sealing assembly includes threaded groove 9, and threaded groove 9 is set up in connecting head 3 inner chamber one side, and the inner chamber other side of connecting head 3 is fixedly connected with limiting ring 10, and limiting ring 10 one side is fixedly connected with sealing ring 11.

[0026] Specifically: the air pump 1 can inflate the air tube 2. A pressure detector is set at the connection between the output end of the air pump 1 and the air tube 2 to observe the pressure change during the test. The air tube 2 is a flexible tube to facilitate connection with the supply and return air ducts. The arc-shaped clamp 8 does not affect the insertion of the connecting block 5 in the default state. When the abutment block 19 presses against one side of the right-angle swing block 7, it drives the arc-shaped clamp 8 to clamp the surface of the connecting block 5. The limiting ring 10 can make the connected air duct and the sealing ring 11 fit tightly. The connector 3 limits the detection sleeve 4, which can not only perform sealing test at the connection during the test, but also ensure that the detection sleeve 4 is supported. Example

[0027] Please see Figures 1-5 Based on Embodiment 1, the leak detection assembly further includes a limiting rod 12, which is slidably connected to both sides of the surface of the connector 3. A first spring 13 is sleeved on the surface of the limiting rod 12, and one end of the first spring 13 is fixedly connected to one side of the surface of the connector 3. Insertion holes 14 are opened on both sides of the inner cavity of the connector 3, and a second spring 15 is fixedly connected to both sides of the inner cavity of the insertion hole 14. One end of the second spring 15 is fixedly connected to one side of the right-angle swing block 7. An infrared imaging camera 16 is fixedly connected to the inner cavity of the detection sleeve 4, and an alarm 17 is fixedly connected to the surface of the detection sleeve 4. One end of the inflation tube 2 is connected to a rotary joint 18, and one end of the rotary joint 18 is movably connected to one end of the connector 3. A slot is opened on one side of the inner cavity of the connecting block 5, and one end of the limiting rod 12 is slidably connected to the inner cavity of the slot. A stop block 19 is fixedly connected to one side of the connecting block 5, and one end of the stop block 19 contacts one side of the right-angle swing block 7.

[0028] Specifically: When the connecting block 5 is inserted into the socket 14, it can squeeze the limiting rod 12. When one end of the limiting rod 12 coincides with the slot of the connecting block 5, the first spring 13 is used to lock one end of the limiting rod 12 into the slot, thereby limiting the connecting block 5. After the connecting block 5 is released from the limiting position by the second spring 15, the right-angle swing block 7 will automatically reset. The infrared imaging camera 16 can scan the surface of the pipe in real time, accurately capture the image information of the leaking part of the pipe, and after finding the leaking part, the alarm 17 will sound an alarm to remind the inspector.

[0029] The working principle of this utility model is as follows: When it is necessary to detect leaks in the air supply and return air ducts of an air conditioner, firstly, the air pump 1 is moved to the required position, and then the connector 3 at one end of the air inflator 2 is connected to one end of the air supply and return air duct to be tested. By rotating the connector 3, the internal thread groove 9 can cooperate with the port of the air supply and return air duct to achieve a stable connection. At the connection, the synergistic effect of the limiting ring 10 and the sealing ring 11 ensures the sealing of the connection, prevents air leakage, and ensures the efficient operation of the system. Then, the air pump 1 is started by the external controller to inflate the air supply and return air duct. At this time, the detection sleeve 4 can perform a sealing test on the connection to prevent air leakage at the connection from affecting the leak detection.

[0030] If there are no issues at the connection, the air pump 1 inflates the supply and return air ducts. When the air pressure detector of the air pump 1 detects a leak in the supply and return air ducts, the limit rod 12 can be pulled to release the limit of the connection block 5 on the detection sleeve 4. Then, the detection sleeve 4 can slide freely on the duct. The infrared imaging camera 16 inside the connector 3 accurately captures the image information of the leaking part of the duct by scanning the duct surface in real time. If a leak is found, the system will automatically sound an alarm and clearly mark the leak location for subsequent maintenance or handling. After the leak is detected, the detection sleeve 4 can be moved to one side of the connector 3, and the connection block 5 can be inserted into the socket 14. The abutment 19 will press against the right-angle swing block 7, so that the arc clamp 8 limits the surface of the connection block 5. At the same time, the limit rod 12 will extend into the slot to reset the detection sleeve 4. This completes the leak detection work of the air conditioning supply and return air ducts.
