Description

Technical Field

[0001] This utility model relates to the field of airtightness testing technology, and in particular to an airtightness testing device for an air conditioner muffler. Background Technology

[0002] The main function of an air conditioner silencer is to reduce noise. Its working principle mainly relies on the interference and absorption of sound waves. When an air conditioner is running, components such as the compressor and fan will generate vibrations and sound waves. These sound waves propagate in the air and form noise. By setting specific structures and materials, silencers can effectively absorb and attenuate these sound waves, thereby achieving the purpose of reducing noise. Common silencer materials include sound-absorbing cotton, foam plastics, and metal mesh. These materials have good sound wave absorption performance and can significantly reduce noise. The design of the silencer also takes into account the smooth flow of air to ensure that the normal operation of the air conditioner is not affected.

[0003] Existing air-conditioning muffler air tightness testing devices, such as the automatic water testing device for air-conditioning mufflers disclosed in application number CN202020196136.5, include a chassis, a turntable, a fixture, and a water tank. The fixture specifically includes a fixture bracket, an inlet pipe plug, an outlet pipe connector seat, an outlet pipe connector, and an inlet pipe end positioning seat. The inlet pipe end of the air-conditioning muffler is positioned and installed on the inlet pipe end positioning seat, and the outlet pipe end of the air-conditioning muffler is connected to the outlet pipe connector. Several air-conditioning mufflers are positioned and fixed in the same fixture in the above manner. The rotation of the turntable drives the fixture containing the air-conditioning mufflers to move to... At the water tank, the air inlet pipe plug descends to seal the air inlet pipe end of the air conditioner muffler. The air source fills each air conditioner muffler with air through the air passage on the air outlet pipe connector seat. The tooling bracket descends to immerse the air conditioner muffler in the water tank for air tightness testing. This method can perform air tightness testing on multiple air conditioner mufflers at once, and continuous air tightness testing is achieved through the rotation of the turntable, resulting in high efficiency of water testing. However, the above technology requires users to observe the product themselves to make a judgment, which is inefficient and burdensome. Therefore, we propose an air conditioner muffler air tightness testing device to solve the above problems. Summary of the Invention

After the test is passed, the voice speaker 3013 and the flash lamp 3014 are used for photoacoustic processing, which, together with the camera 1025, makes it easier for the user to quickly obtain the problematic muffler body 4.

[0048] The working principle of this utility model is as follows: In use, the silencer body 4 to be tested is sealed and fitted through the sealing sleeve 3012. Then, the glass frame 107 is attached to both ends of the water tank shell 103 using adhesive, so that the glass frame 107 fits with the tempered glass 108 for easy observation by the user. The water tank inner base 105 is welded to the inner sides of the water tank shell 103 through the inclined support frame 104, and the lighting 106 is turned on. Then, the control panel 1014 at one end of the upper frame 1013 is used to operate and output commands, and the upper drain valve block 1012 is closed. Then, the water inlet valve block 1011 is opened, so that the water fills the area between the water tank shell 103 and the water tank inner base 105. Then, the water is used... The air-cooled fan 1016 on the outer side of the bolted bracket 1015 generates airflow to dissipate heat from the external connecting pipe 1021 and finned plate 1022. This air-cooling of the external connecting pipe 1021 and finned plate 1022, in conjunction with the pipe base 1017, inner node compartment 1018, inner connecting pipe 1019, and outer node compartment 1020, provides continuous cooling to the water inside the equipment. The testing process, displayed on the tempered glass 108, is observed in real-time by a camera 1025 located inside the empty tank shell 1024. Then, the drive motor 205 located at one end of the speed transmission housing 204 below the assembly plate 203 outputs power to drive the output end. The drive motor 205 outputs power to drive the meshing gear set 206 for meshing transmission. When the meshing gear set 206 is meshing, the rotating column 207 rotates, causing the turntable 208, the annular mounting frame 209, and the ball bearings 2010 to rotate effectively, so that the top sleeve plate 2011 moves to the appropriate target orientation. Then, the gear motor 2013 on the side of the node compartment 2012 outputs power to drive the output end, so that when the helical gear set 2014 is meshing, the threaded compartment 2015 and the bolt strip 2016 spiral, causing the crossbeam 2017 to move to the appropriate position. Finally, the drive cylinder 302 above the cylinder base 301 outputs power... The power source drives the output end to operate, causing the telescopic frame 303 to extend and retract, thereby adjusting the lifting beam 304, bolt connecting strip 305, and assembly frame 306 to a suitable height position so that the silencer body 4 to be tested can touch the water. When testing is required, the valve pipe 3010 is opened, and the air compressor 3011 is started to output power to drive the output end to output gas through the pipeline to the air distribution base 308 and the air connecting pipe 309 to the sealing sleeve 3012 to press the silencer body 4 in and out to achieve the testing effect. After the test is passed, the voice speaker 3013 and the flashlight 3014 perform light and sound processing, which, together with the camera 1025, allows the user to quickly obtain the problematic silencer body 4.
