Description

Technical Field

[0001] The utility model relates to an air compressor. Background Art

[0002] With the rapid development of the industrial control industry, air compressors have become essential equipment across various industries. Variable frequency air compressors, due to their effectiveness in energy conservation and emission reduction, are gradually gaining acceptance among manufacturers. This is accompanied by a continuous improvement in people's quality of life. Simultaneously, with the deepening implementation of environmental policies, environmental monitoring indicators are becoming increasingly refined. The air compressor industry has long considered compressor noise a key indicator, but this is limited to factory monitoring, with users often overlooking online noise monitoring during operation. Summary of the Invention

[0003] In order to overcome the above-mentioned deficiencies in the prior art, the utility model provides an air compressor whose noise can be detected by the user during use.

[0004] The utility model is realized by the following technical solutions:

[0005] A noise-detectable air compressor includes a frequency converter, a motor connected to the frequency converter and controlled by the frequency converter, an air compressor main unit connected to the motor, the air compressor main unit connected to an intake valve, an air volume adjustment flap is provided in the intake valve, a cylinder is provided on one side of the intake valve, an axial end of the air volume adjustment flap passes through the intake valve and is connected to a cylinder rod of the cylinder, the air volume adjustment flap is driven to rotate back and forth by the cylinder rod, and is characterized in that: the cylinder rod is also transmission-connected to a support frame and drives the support frame to rotate back and forth, the outer end of the support frame extends outward away from the air compressor main unit, and a noise detection unit is provided at the outer end of the support frame.

[0006] Preferably, the cylinder rod is rotatably connected to one end of a connecting rod block through a connecting rod, and an axial end of the air volume regulating flap is fixed on the connecting hole of the connecting rod block. The reciprocating motion of the cylinder rod drives the connecting rod block to rotate reciprocatingly, and the reciprocating rotation of the connecting rod block drives the air volume regulating flap to rotate reciprocatingly to adjust the opening size of the intake valve.

[0007] Preferably, the other end of the connecting rod block is laterally opened, and the lateral opening is connected to the connecting hole, and screw holes are provided on the connecting rod blocks on both sides of the lateral opening. The inner end of the support frame is configured to be a screw shape, and the inner end of the support frame is penetrated by a screw hole and locked with a nut.

[0008] Preferably, one axial end of the air volume regulating flap is fixed to the connecting hole via a pin.

[0009] Preferably, the noise detection unit is connected to the controller, and the controller is connected to the warning unit.

[0010] Because existing technologies lack noise detection capabilities, this application utilizes existing structures to add noise detection capabilities. By extending a noise detection unit from the support frame to the exterior of the air compressor, the noise detection unit can detect noise within a specific space. To maximize the detectable space, the support frame is rotatable through a certain angle. This angular rotation of the support frame is achieved by utilizing certain rotating structures on existing intake valves. The intake valve primarily regulates air volume through its cylinder. The reciprocating motion of the cylinder rod, through the connecting rod block rotatably connected to it, causes the air volume adjustment flap, fixed to the connecting rod block, to rotate through a certain angle. The rotation angle is typically 90 degrees, enabling adjustment of the intake valve opening. When the connecting rod block is fixedly connected to the air volume adjustment flap, a screw is inserted through the lateral opening of the connecting rod block to further secure it. By configuring the inner end of the support frame with a screw to lock the lateral opening, the support frame can rotate synchronously with the connecting rod block. A 90-degree rotation angle fully meets the requirements for spatial noise detection.

[0011] The beneficial effects of this utility model are as follows: the utility model realizes spatial noise detection by using a noise detection unit remote from the air compressor main unit, and utilizes the existing rotation mechanism in the air compressor to rotate the noise detection unit within a certain angle, thereby achieving a wider range of spatial detection, eliminating the need for a dedicated rotating structure. The utility model realizes the noise detection function, is easy to manufacture, and is safer and more reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The utility model is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0016] like Figure 1 、 2 As shown in Figure 3, a noise-detectable air compressor includes a frequency converter, a motor connected to the frequency converter and controlled by the frequency converter, an air compressor main unit connected to the motor, the air compressor main unit is connected to an air intake valve 8, an air volume regulating flap 9 is provided in the air intake valve, a cylinder 1 is provided on one side of the air intake valve, an axial end 3 of the air volume regulating flap passes through the air intake valve 8 and is connected to a cylinder rod 2 of the cylinder, the air volume regulating flap 9 is driven to reciprocate through the cylinder rod, the cylinder rod is also connected to a support frame 4 and drives the support frame to reciprocate, the outer end of the support frame extends outward away from the air compressor main unit, and a noise detection unit 5 is provided at the outer end of the support frame.

[0017] The cylinder rod 2 is rotatably connected to one end of a connecting rod block 7 via a connecting rod. The axial end 3 of the air volume regulating flap is fixed to the connecting hole of the connecting rod block 7, and the axial end of the air volume regulating flap is fixed to the connecting hole via a pin. The other end of the connecting rod block has a lateral opening 6, and the lateral opening 6 is connected to the connecting hole. The connecting rod block has screw holes on both sides of the lateral opening. The inner end 10 of the support frame is configured as a screw, and the inner end of the support frame is penetrated by screw holes and locked with a nut 11. The reciprocating motion of the cylinder rod drives the connecting rod block 7 to rotate back and forth. The reciprocating rotation of the connecting rod block drives the reciprocating rotation of the air volume regulating flap 9, and at the same time drives the reciprocating motion of the support frame. The air volume regulating flap 9 adjusts the opening size of the intake valve. The support frame enables the noise detection unit 5 at its outer end to detect noise at different angles.

[0018] The noise detection unit is connected to the controller, and the controller is connected to the warning unit. When the noise reaches a certain level, a warning is issued.

[0019] The noise detection in this application is mainly to detect the spatial noise within a certain angle. Since the fan is the main noise source, the noise detection unit 5 is mainly oriented towards the fan. The outer end of the support frame is away from the air compressor body and is set towards the fan.

[0020] Because existing technologies lack a noise detection function during user use, this application adds a noise detection function without adding an additional rotating structure, but instead utilizes the existing rotating structure. In this application, a noise detection unit 5 is provided by extending the support frame 4 toward the exterior of the air compressor. This unit can detect noise within a specific space. To maximize the detectable space, the support frame is rotatable to a certain angle, allowing detection of noise at different angles. This angular rotation of the support frame is achieved by utilizing the rotating structure of the existing intake valve 8.

[0021] The air volume adjustment of the intake valve is mainly achieved through its cylinder. The cylinder rod 2 reciprocates, and through the connecting rod block rotatably connected thereto, the air volume adjustment flap 9 fixedly connected to the connecting rod block rotates at a certain angle. Generally, the rotation angle is 90 degrees, which can adjust the opening of the intake valve. When the connecting rod block is fixedly connected to the air volume adjustment flap, a screw is generally passed through the lateral opening 6 on the connecting rod block 7 to further lock it. The inner end of the support frame 4 is set as a screw to lock the lateral opening, so that the support frame can rotate synchronously with the rotation of the connecting rod block 7. The support frame 4 not only further locks the fixed connection between the air volume adjustment flap and the connecting rod block, but also allows the support frame 4 itself to rotate at a certain angle along with the connecting rod block 7. The rotation angle of 90 degrees can fully meet its spatial noise detection requirements.

[0022] This utility model achieves spatial noise detection by using a noise detection unit located away from the air compressor main unit. The noise detection unit is then rotated within a certain angle using the existing rotation mechanism in the air compressor, enabling noise detection at different angles and a wider range of spatial detection. This utility model eliminates the need for a dedicated rotation mechanism and achieves noise detection with fewer parts using the existing structure, making it easier to manufacture and more secure and reliable.
