Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, specifically to a silent air compressor. Background Technology

[0002] An air compressor, also known as an air compressor, is a device that converts the mechanical energy of a prime mover into the pressure energy of a gas. Its core function is to compress air to a higher pressure to provide power or transport gas in various industrial applications.

[0003] For example, the announcement number is CN213743885U (named "A Silent Air Compressor"), which includes a main body. A first mounting port and a second mounting port are respectively opened on both sides of the main body. A first connecting groove is opened on the inner wall of the first mounting port. A first pressure spring is fixedly connected to the inner wall of the first connecting groove. A first snap-fit ​​block is fixedly connected to one free end of the first pressure spring. One side surface of the first snap-fit ​​block is arc-shaped. One outer surface of the first snap-fit ​​block is movably inserted into the inner surface of the first connecting groove. A first noise reduction device is provided on the inner wall of the first mounting port. A first connecting port and a second connecting port are respectively opened on the inner top walls of the first and second mounting ports. A second pressure spring is fixedly connected to the inner top wall of the connection port via a first connecting block. A second connecting block is fixedly connected to the lower surface of the first connecting block, and a first connecting rod is fixedly connected to the lower surface of the first connecting block. A sound-absorbing layer is fixedly connected to the inner surface of the noise reduction port, and slag wool is placed inside the sound-absorbing layer. This achieves the effect of noise reduction when air enters the first installation port. In use, when air enters the first installation port, the air enters the noise reduction port inside the noise reduction ball. Because the surface of the noise reduction port is irregularly shaped, the sound-absorbing layer inside the noise reduction port absorbs the noise when the air passes through the noise reduction port, thereby achieving the effect of noise reduction and solving the problem of large noise generated when air enters the first installation port.

[0004] The aforementioned air compressor uses a sound-absorbing structure to reduce noise during use, but it lacks an effective dust suppression and protection mechanism, which makes the motor structure of the air compressor prone to dust accumulation, resulting in a loud noise problem during use. Therefore, we provide a silent air compressor. Utility Model Content

[0005] The purpose of this utility model is to provide a silent air compressor to solve the problem mentioned in the background art that the existing air compressors reduce noise and quiet down during use through sound absorption structures, but the air compressors lack effective dust suppression and protection mechanisms, which makes the motor structure of the air compressor easy to accumulate dust and cause loud noise during use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a silent air compressor, including an air tank, an integrally formed top platform at the upper end of the air tank, a copper wire motor at the upper end of the top platform, a solenoid valve on one side of the copper wire motor, and the solenoid valve communicating with the interior of the air tank.

[0007] Also includes:

[0008] An air outlet is located at the air outlet end of the solenoid valve, and a silencing mechanism is installed on the air outlet. The silencing mechanism has an air guiding channel inside, a microporous inner liner tube is installed on the inner wall of the air guiding channel, and sound-absorbing cotton is installed on the outer wall of the microporous inner liner tube.

[0009] A dust suppression cover is installed on the outside of the copper wire motor, and end caps are installed at both ends of the dust suppression cover. A connecting block is integrally formed on the top of the end cap.

[0010] Preferably, anti-detachment sliding grooves are provided on both outer walls of the top platform, and magnetic sliders are slidably installed inside the two anti-detachment sliding grooves. The magnetic sliders are connected to one end of the anti-detachment sliding groove by magnets embedded at one end. The two magnetic sliders and the dust suppression cover are an integral structure.

[0011] Preferably, an inner roller is provided in the internal slot of the magnetic slider. The inner roller is rotatably connected to the magnetic slider through a bearing and a rotating shaft. The dust suppression cover is movably connected to the anti-detachment slide groove through the inner roller.

[0012] Preferably, the top of the dust suppression cover is provided with two top connection holes, and connecting screws are provided at the connection positions of the two connecting blocks and the two top connection holes. The end cover is assembled and connected to the dust suppression cover by connecting screws.

[0013] Preferably, one end of the silencing mechanism is provided with a threaded interface, which is connected to the interior of the air guide channel. The silencing mechanism is screwed and sealed to the air outlet through the threaded interface.

[0014] Preferably, the bottom support of the gas storage tank is provided with two casters, and a balance support rod is provided on one side of the two casters. The balance support rod and the gas storage tank are an integral structure, and the balance support rod and the two casters are located on the same horizontal line.

[0015] Preferably, one end of the top platform is provided with a pull handle, and the pull handle and the top platform are an integral structure.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model, by removing the dust suppression cover and two end caps (or simply removing the end caps from the top base), allows for noise reduction of the air compressor through the dust suppression cover in conjunction with the sound insulation cover on the copper wire motor body. After air compression, the dust suppression cover is reinstalled on the top base via the guiding movement of the magnetic slider and the anti-detachment slide groove, thus protecting the copper wire motor. Finally, the connecting block and dust suppression cover are fixed with connecting screws, and the end caps are installed at both ends of the dust suppression cover, further enhancing the coverage of the dust suppression cover and preventing dust accumulation inside the air compressor when not in use. This overcomes the problem that existing air compressors rely on sound-absorbing structures for noise reduction during use, but lack effective dust suppression and protection mechanisms, leading to dust accumulation on the motor structure and excessive noise during operation.

[0018] 2. The compressed gas is discharged through the air outlet. After passing through the silencer, the gas is absorbed by the internal microporous liner tube and sound-absorbing cotton, thus reducing the noise of the gas discharged through the air guide channel.

[0019] 3. By pulling the pull handle, the air compressor is moved to ground position. During the air compression process, it is supported by the balance support rod and the moving wheels, which improves the stability of the air compressor during use and avoids noise problems caused by uneven placement.

[0030] During use, compressed gas is discharged through the outlet 17. After passing through the silencer 9, the discharged gas is absorbed by the internal microporous liner 20 and sound-absorbing cotton 19, thereby reducing noise in the gas discharged through the air guide channel 21. When compressing air, the dust suppression cover 11 and the two end covers 15 are removed, or only the end covers 15 are removed from the top base 4. The dust suppression cover 11, in conjunction with the soundproof cover on the copper wire motor 10, can be used to reduce noise in the air compressor. After the air is compressed, the dust suppression cover 11 is reinstalled on the top base by the guiding movement of the magnetic slider 7 and the anti-detachment slide groove 5. The upper end of the base 4 allows the dust suppression cover 11 to shield and protect the copper wire motor 10. Finally, the connecting block 13 and the dust suppression cover 11 are fixed by the connecting screw 14, and the end cover 15 is installed on both ends of the dust suppression cover 11 to further enhance the outer coverage of the dust suppression cover 11 and prevent dust from accumulating inside the air compressor when it is not in use. By pulling the pull handle 6, the air compressor is moved to ground. During the air compression process, it is grounded and supported by the balance support rod 3 and the moving wheel 2, which improves the stability of the air compressor during use and avoids noise problems caused by uneven placement of the air compressor during use.
