[0046] See also Figure 1 , Figure 2The utility model provides an air compressor waste heat recovery device, which is connected to the air compressor 100 and includes: a shell 200, a recovery component 300, and at least two connecting components 400. The shell 200 is provided with a cavity for accommodating the air compressor 100. The recovery component 300 includes an air inlet pipe 310, an air outlet pipe 320 and a circulating heat exchanger 330. The air inlet pipe 310 and the air outlet pipe 320 are respectively connected to the interior of the shell 200 and the interior of the circulating heat exchanger 330 for heat exchange. The connecting component 400 includes a sliding member 410 and a buffer member 420. At least two sliding members 410 are arranged at intervals from each other and are connected to the air compressor 100.

The buffer member 420 is connected to the sliding member 410 and the inner wall of the shell 200 to provide a restoring force for the sliding member 410 to automatically reset after sliding.

[0047] In the present device, a cavity for accommodating the air compressor 100 is opened in the shell 200, which is used to collect the heat generated by the air compressor 100 inside the shell 200. The circulating heat exchange component 330 is connected to the interior of the shell 200 through the air inlet pipe 310 and the air outlet pipe 320 to realize heat exchange.

The buffer member 420 is connected to the sliding member 410 and the inner wall of the shell 200, and is used to provide a restoring force for the sliding member 410 to automatically reset after sliding relative to the shell 200.

[0048] Compared with the prior art, by providing a sliding member 410 and a buffer member 420, the vibration generated by the air compressor 100 during operation is converted into a thrust for pushing the sliding member 410 to slide, and the restoring force generated by the buffer member 420 is used to offset this thrust, thereby achieving the purpose of reducing resonance and noise. It not only has a simple structure but also has a stable connection, and can solve the technical problem in the prior art that the vibration generated by the air compressor 100 during operation is transmitted to the shell 200 of the waste heat recovery chamber, thereby causing the shell 200 of the recovery chamber to generate resonance and noise.

[0049] Furthermore, the shell 200 in the present device is a sealed metal shell 200, wherein the circulating heat exchange component 330 is a heat exchanger that is common and easy to purchase on the market, which can circulate heat exchange, exchange and collect the heat in the shell 200 into the heat exchanger, and cool down the temperature inside the shell 200. This is a conventional setting known to those skilled in the art and will not be elaborated here.

[0050] like Figure 1 , Figure 2 As shown, the sliding member 410 includes a supporting rod 411 and a connecting bar 412 .

[0051] As an implementation method, Figure 4 As shown, at least two slide grooves are formed on the bottom inner wall of the housing 200 , one end of the support rod 411 is connected to the air compressor 100 , and the other end is slidably inserted into the slide groove.

[0052] The sliding connection between the air compressor 100 and the housing 200 is achieved through the sliding cooperation between the sliding groove and the support rod 411.

[0053] As another implementation method, Figure 1 , Figure 2 As shown, the connecting strip 412 is disposed in close contact with the circumferential outer wall of the air compressor 100 and is connected to the air compressor 100 , and one ends of the plurality of support rods 411 are all connected to the connecting strip 412 .

[0054] Specifically, the number of support rods 411 in this device is four, two support rods 411 form a group, and the two groups of support rods 411 are respectively arranged at intervals on both sides of the air compressor 100, and the two support rods 411 on the same side are connected by two connecting strips 412 to form a whole, which is used to improve the stability of the device.

[0055] like Figures 1 to 4 As shown, the buffer member 420 includes a rack 421 , a buffer gear 422 and at least one first elastic portion 423 , a rotating shaft 424 , at least one second elastic portion 425 , a pressing plate 426 , and a plurality of guide rods 427 .

[0056] Among them, the inner wall of the slide groove is also provided with a groove, the rack 421 is arranged along the guide of the support rod 411 and is connected to the support rod 411, the buffer gear 422 is rotated and built into the groove and meshes with the rack 421, one end of the first elastic part 423 is connected to the buffer gear 422, and the other end is connected to the inner wall of the groove, which is used to provide a restoring force for the buffer gear 422 to automatically reset after rotation.

[0057] The relative sliding of the support rod 411 relative to the slide slot is converted into rotation by the meshing between the rack 421 and the buffer gear 422, and the elastic restoring force generated by the first elastic part 423 is used to limit the rotation, so as to achieve the effect of buffering and offsetting.

[0058] Furthermore, the rack 421 and the buffer gear 422 are common and easily purchased gear and rack 421 meshing structures on the market, which are conventional settings well known to those skilled in the art and will not be described in detail.

[0059] As an implementation method, Figure 3As shown, the two ends of the rotating shaft 424 are respectively rotatably connected to the inner walls of the two opposite sides of the groove, the buffer gear 422 is fixedly sleeved on the rotating shaft 424 and meshed with the rack 421, the first elastic part 423 is a torsion spring, the torsion spring is sleeved on the rotating shaft 424, and one end of the torsion spring is fixedly connected to the rotating shaft 424, and the other end is connected to the inner wall of the groove.

[0060] The rotating shaft 424 serves as a connection for the rotation of the buffer gear 422 .

[0061] As a preferred embodiment, the first elastic part 423 is a torsion spring, which can generate a restoring force for the rotating shaft 424 to automatically return to its original position after rotation. The torsion spring is a common and easy-to-purchase device on the market, and will not be described in detail here.

[0062] As another implementation method, Figure 3 As shown, one end of the second elastic portion 425 is connected to the bottom inner wall of the slide groove, and the other end is arranged relative to the other end of the support rod 411, so as to provide a restoring force for the support rod 411 to automatically return to its original position after sliding.

[0063] The second elastic portion 425 is used to assist the buffer structure composed of the rack 421, the buffer gear 422 and the torsion spring, so as to improve the stability of the device.

[0064] As a preferred implementation method, Figure 4 As shown, there are multiple second elastic parts 425 in the buffer member 420 , and the multiple second elastic parts 425 are spaced apart from each other and evenly disposed on the inner wall of the slide groove.

[0065] The plurality of second elastic portions 425 are spaced apart from each other to provide stable buffering and offsetting performance.

[0066] Furthermore, the second elastic portion 425 here is a spring, a spring sheet, an elastic block, etc. that are common and easy to purchase on the market. This is a conventional setting known to those skilled in the art and will not be described in detail.

[0067] As an implementation method, Figure 4 As shown, the slide groove has a large diameter section and a small diameter section. The small diameter section of the slide groove is arranged close to the air compressor 100 relative to the large diameter section. The pressure plate 426 is slidably built into the large diameter section of the slide groove, and the pressure plate 426 is arranged relative to the other end of the support rod 411, and is connected to the other ends of multiple second elastic parts 425. The pressure plate 426 can abut against the other end of the support rod 411.

[0068] The contact area between the support rod 411 and the multiple springs can be increased by the pressure plate 426, so that the pressure on the support rod 411 is evenly transmitted and distributed to the multiple second elastic parts 425, which can improve the stability of the device.

[0069] As another implementation method, Figure 4 As shown, a plurality of guide holes are formed on the bottom inner wall of the large diameter section of the slide groove, and the guide rods 427 are arranged one by one corresponding to the guide holes. One end of the guide rod 427 is connected to the pressure plate 426, and the other end is slidably inserted into the guide hole.

[0070] The cooperation between the guide rod 427 and the guide hole plays a connecting and guiding role in the sliding of the pressing plate 426 relative to the sliding groove.

[0071] like Figure 1 As shown, the connecting assembly 400 also includes a placement plate 430 and at least two third elastic parts 440. The placement plate 430 is arranged between the connecting strip 412 and the bottom inner wall of the shell 200 and is connected to the connecting strip 412. At least two third elastic parts 440 are arranged on both sides of the placement plate 430, and one end of the third elastic part 440 is connected to the inner wall of the shell 200 and the other end is connected to the placement plate 430.

[0072] The connecting strip 412 and the air compressor 100 are connected to the shell 200 via the placement plate 430. At the same time, at least two third elastic parts 440 are arranged on the side of the placement plate 430 to reduce the shaking of the placement plate 430 and the air compressor 100 in the left and right directions, so as to improve the stability of the device.

[0073] Furthermore, the third elastic part 440 here is a spring, a spring sheet, an elastic block, etc. that are common and easy to purchase on the market. This is a conventional setting known to those skilled in the art and will not be described in detail.

[0074] The specific working process of the utility model is that a cavity for accommodating the air compressor 100 is provided in the shell 200, and the heat generated by the air compressor 100 is collected inside the shell 200. The circulating heat exchanger 330 is connected to the inside of the shell 200 through the air inlet pipe 310 and the air outlet pipe 320, and is used to achieve heat exchange. At least two sliding members 410 are arranged at intervals from each other and are both connected to the air compressor 100, and the sliding member 410 can slide relative to the shell 200. The buffer member 420 is connected to the sliding member 410 and the inner wall of the shell 200, and is used to provide a restoring force for the sliding member 410 to automatically reset after sliding relative to the shell 200. Compared with the prior art, by setting the sliding member 410 and the buffer member 420, the vibration generated by the air compressor 100 during operation is converted into a thrust for pushing the sliding member 410 to slide, and the restoring force generated by the buffer member 420 is used to offset this thrust, thereby achieving the purpose of reducing resonance and noise. Not only is the structure simple, but the connection is stable.

[0075] When in use, the user first connects the air compressor 100 to the placement plate 430. Then, when the air compressor 100 is working, the circulating heat exchange component 330 continuously exchanges heat with the interior of the shell 200 to recycle the heat. Then, the vibration generated by the air compressor 100 causes the support rod 411 to slide relative to the slide groove. During the sliding process, the rack 421 continuously engages with the buffer gear 422 and is offset by the elastic restoring force generated by the first elastic part 423. Finally, the elastic restoring forces generated by the second elastic part 425 and the third elastic part 440 can also buffer and offset the relative sliding of the placement plate 430, thereby reducing resonance and noise.

[0076] The device, through the above structure, can solve the technical problem in the prior art that the vibration generated when the air compressor 100 is working is transmitted to the shell 200 of the waste heat recovery chamber, thereby causing the shell 200 of the recovery chamber to generate resonance and noise.

[0077] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
