[0028] Example

[0029] Please see Figures 1-5 This utility model provides a technical solution: a commercial air conditioning water pipe expansion tank, including a first tank body 1, a second tank body 2 welded to one side of the first tank body 1, a cover plate 4 connected to the bottom side of the second tank body 2, and a plurality of bolts 8 connecting the cover plate 4 and the second tank body 2; an air bladder 6 for water pipe buffer expansion is bonded to the top side of the first tank body 1, the air bladder 6 being made of EPDM environmentally friendly rubber; two mounting plates 5 are installed on one side of the second tank body 2, the mounting plates 5 being used to connect to the inner wall of the commercial air conditioner, and a warning component 3 is provided on one side of the mounting plates 5; a water inlet pipe 7 is welded to the bottom of the cover plate 4;

[0030] The water inlet pipe 7 is connected to the inner side of the first tank 1 and the second tank 2. The outer side of the water inlet pipe 7 is threaded. The thickness of the first tank 1, the second tank 2, the cover plate 4 and the mounting plate 5 is 2 mm. The first tank 1, the second tank 2, the cover plate 4, the mounting plate 5 and the water inlet pipe 7 are made of stainless steel. The expansion tank composed of the first tank 1, the second tank 2, the cover plate 4, the mounting plate 5 and the air bladder 6 has a volume of 1.8 liters. The maximum working pressure of the expansion tank is 6 bar and the maximum working temperature is -35℃~150℃.

[0031] The prompt component 3 includes a connecting plate 33. Two fixing brackets 32 are fixed to one side of the connecting plate 33. A first sliding groove 39 is formed inside each fixing bracket 32. A sliding plate 35 is slidably connected to the inner side of the first sliding groove 39. Two second sliding grooves 310 are formed on one side of the connecting plate 33. A sliding rod 34 pushes the sliding plate 35 to slide inside the first sliding groove 39, and the sliding plate 35 stretches the tension spring 38. A sliding rod 34 is slidably connected to the inner side of the second sliding groove 310. One side of the sliding rod 34 is fixed to one side of the sliding plate 35. A switch 36 located on one side of the sliding plate 35 is installed on the inner wall of the first sliding groove 39. After the mounting plate 5 becomes loose from the inner wall of the commercial air conditioner, the connection... The gap between plate 33 and the inner wall of the commercial air conditioner is increased. Under the tension of spring 38, the slide rod 34 moves to the side of connecting plate 33. The inner wall of the first slide groove 39 is fixed with a limiting block 37 located on one side of switch 36. A buzzer 31 is installed on one side of mounting plate 5. The output terminal of switch 36 is electrically connected to the input terminal of buzzer 31. Switch 36 and buzzer 31 are respectively connected to the power supply of air conditioner. The slide plate 35 just touches the contact of switch 36, triggering switch 36. After switch 36 is triggered, buzzer 31 produces an audible prompt. After the user or maintenance personnel hear the sound of buzzer 31, they can know that the expansion tank is loose at this time.

[0032] A tension spring 38 is sleeved on the outside of the slide rod 34. The two ends of the tension spring 38 are respectively connected to one side of the slide plate 35 and the first slide groove 39. A maintenance cover (not shown in the figure) is bolted to one side of the fixing bracket 32. The tension spring 38 can be replaced by removing the maintenance cover. Both sides of the connecting plate 33 are fixed between the two mounting plates 5. When the gap between the mounting plate 5 and the inner wall of the commercial air conditioner is greater than the contact stroke of the switch 36, the buzzer 31 will make a sound. When the gap is small, it will not affect the normal operation of the expansion tank, so the buzzer 31 will not make a sound.

[0033] Working principle: When an expansion tank is needed inside a commercial air conditioner, the mounting plate 5 is connected to the outer shell of the commercial air conditioner. At this time, the tank can be installed vertically or horizontally under the action of the mounting plate 5. The installation is simple and convenient. The materials of the first tank 1, the second tank 2, the cover plate 4, the mounting plate 5 and the first tank 1 are stainless steel, which will not rust in the air conditioning water system and has a long service life.

[0034] After the mounting plate 5 is installed close to the inner wall of the commercial air conditioner, the inner wall will push the slide rod 34 to slide in the second slide groove 310. At the same time, the slide rod 34 pushes the slide plate 35 to slide inside the first slide groove 39, and the slide plate 35 stretches the tension spring 38. When the mounting plate 5 becomes loose from the inner wall of the commercial air conditioner, the gap between the connecting plate 33 and the inner wall of the commercial air conditioner increases. Under the tension of the tension spring 38, the slide rod 34 moves to the side of the connecting plate 33, just enough to make the slide plate 35 abut against the contact point of the switch 36, triggering the switch 36. After the switch 36 is triggered, the buzzer 31 will produce an audible prompt. After the user or maintenance personnel hear the sound of the buzzer 31, they will know that the expansion tank is loose at this time.

[0035] In summary, by using stainless steel for key components such as the first tank 1, the second tank 2, the cover plate 4, and the mounting plate 5, the expansion tank can be installed vertically or horizontally, adapting to different installation environments and space constraints. This simplifies the installation process and improves installation efficiency.

[0036] When the connection between the mounting plate 5 and the inner wall of the commercial air conditioner becomes loose, the prompting component 3 can detect this change immediately. Through the linkage mechanism of the slide bar 34, the sliding plate 35 and the tension spring 38, as well as the cooperation of the switch 36 and the buzzer 31, the buzzer 31 will sound an alarm once the installation becomes loose. The immediate feedback mechanism helps users or maintenance personnel to quickly find the problem and avoid potential safety hazards.
