Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to an air compressor with a noise reduction function structure. Background Art

[0002] An air compressor is a machine that compresses air into high-pressure gas. It compresses a large amount of air into a closed space to increase the pressure and density of the air, so that the air can be stored and used more efficiently. The working principle of an air compressor is to compress the air to a high-pressure state through a compressor, and then store the high-pressure gas in a gas tank. When compressed air is needed, the compressor will release the gas in the gas tank and transport it to the place where it is needed through a pipeline. It is widely used in various industrial fields, such as manufacturing, construction, food processing, etc.

[0003] When the existing air compressor is working, it filters the external air through the filter and then sucks it into the device, compresses it, and then stores it in the air storage tank. Since the air compressor needs the filter to quickly suck in a large amount of air for compression, a large suction noise will be generated when the filter sucks in air, which will cause noise pollution to the outside world and reduce the practicality of the device.

[0004] Therefore, the utility model provides an air compressor with a noise reduction function structure to meet the demand. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an air compressor with a silencer function structure, by arranging an air intake component and a silencer component, so that the device can collect air in advance through the air intake component, and increase the area of ​​the air intake through the air intake hopper with a gradually larger diameter at the front end, thereby accelerating the air intake efficiency, and dividing the internal space of the air supply pipe into multiple spaces through multiple silencer components, and through the design of gradually reducing the diameter of the inner plate, the air will go through a process of entering a large space from a small space when passing through each silencer component, so that the flow rate of the air inside the air supply pipe is slowed down, and the kinetic energy of the air impact is absorbed through the design of multiple spaces, thereby isolating the noise generated when the air quickly hits the object and a large amount of air gathers and circulates when the air is inhaled. The above arrangement can solve the problem that the prior art needs the filter to quickly inhale a large amount of air in actual work for compression. Therefore, when the filter inhales air, a large inhalation noise will be generated, which will cause noise pollution to the outside world and reduce the practicality of the device.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] An air compressor with a silencer function structure comprises an air storage tank, wherein the top of the air storage tank is fixedly connected with a compression device, a control panel and a motor in sequence from left to right, both sides of the top of the compression device are fixedly connected with a graded compression mechanism, and the tops of the two graded compression mechanisms are fixedly connected with a same compressed air pipe; a filter assembly, wherein the filter assembly is used to filter air and is connected to the compressed air pipe; an air intake assembly, wherein the air intake assembly is used to pre-collect air and is connected to the filter assembly; and a silencer assembly, wherein the silencer assembly is used to eliminate noise generated when inhaling air and is connected to the air intake assembly.

[0008] Optionally, the filter assembly includes a mounting tube threadedly connected to the inner side of the compressed air pipe, a filter tube is fixedly connected to the other side of the mounting tube, a tube cover is threadedly connected to the other side of the filter tube, and a filter plate is fixedly connected to the inner side of the tube cover.

[0009] Optionally, the air intake assembly includes an air delivery pipe screwed to the pipe cover and the outer side of the filter tube, and the other side of the air delivery pipe is fixedly connected to an air intake hopper.

[0010] Optionally, threads are provided on the outer sides of the mounting tube and the tube cover, and on the outer side of the filter tube near one end of the tube cover, anti-slip sleeves are fixedly connected to the outer sides of the filter tube and the gas pipe, and a filter element is placed inside the filter tube.

[0011] Optionally, the silencer assembly includes an outer ring fixedly connected to the inner side of the air pipe, an inner plate fixedly connected to the inner side of the outer ring, and a vent hole is provided on the inner side of the inner plate.

[0012] Optionally, the number of the silencer components is seven, which are evenly distributed on the inner side of the air pipe, the connection between the outer ring and the inner plate is an arc shape that is concave inward, and the diameter of the inner plate gradually decreases toward the side close to the air intake scoop.

[0013] Optionally, one side of the compressed air pipe away from the filter assembly is fixedly connected to a transport pipe, and the other side of the transport pipe is fixedly connected to the top of the air storage tank.

[0014] Optionally, a guardrail is fixedly connected to one side of the gas storage tank, a fan is rotatably connected to a side of the compression device close to the guardrail, a leather ring is sleeved on the outer side of the fan, and the fan and the motor are transmission-connected via the leather ring.

[0015] Compared with the prior art, the utility model has at least the following beneficial effects:

[0016] In the above scheme, by arranging an air intake component and a silencer component, the device can collect air in advance through the air intake component, and increase the area of ​​air intake through the air intake hopper with a gradually increasing diameter at the front end, thereby accelerating the air intake efficiency. The internal space of the air pipe is divided into multiple spaces through multiple silencer components, and the design of gradually reducing the diameter of the inner plate makes the air go through a process from a small space to a large space when passing through each silencer component, so that the flow rate of the air inside the air pipe is slowed down, and the kinetic energy of the air impact is absorbed through the design of multiple spaces, thereby isolating the noise generated when the air quickly hits the object when the air is inhaled and when a large amount of air gathers and circulates.

[0017] By arranging an outer ring and an inner plate inside the silencer assembly, part of the air that does not pass through the vent hole at the first time will flow back along the curvature of the outer ring and the inner plate, and the air will be divided into multiple branches in different directions, thereby avoiding the air directly impacting the inner plate and generating additional kinetic energy noise. In addition, through the cavity formed between multiple outer rings and inner plates, when the air circulates inside the cavity, a resonance effect will be generated, and the same resonance frequency will be maintained as the air, so as to further reduce the kinetic energy and noise generated by the air when it circulates, further enhance the silencing effect of the silencer assembly, and increase the practicality of the device.

[0033] like Figures 1 to 6 As shown, an embodiment of the utility model provides an air compressor with a silencer function structure, including an air storage tank 1, the top of the air storage tank 1 is fixedly connected with a compression device 2, a control panel 3 and a motor 4 from left to right in sequence, both sides of the top of the compression device 2 are fixedly connected with a graded compression mechanism 5, and the tops of the two graded compression mechanisms 5 are fixedly connected with a same compressed air pipe 6; a filter assembly 8, the filter assembly 8 is used to filter the air, and the filter assembly 8 is connected to the compressed air pipe 6; an air intake assembly 9, the air intake assembly 9 is used to pre-collect the air, and the air intake assembly 9 is connected to the filter assembly 8 The filter assembly 8 includes a mounting tube 804 threadedly connected to the inner side of the compressed air pipe 6, a filter tube 801 is fixedly connected to the other side of the mounting tube 804, a tube cover 802 is threadedly connected to the other side of the filter tube 801, a filter plate 803 is fixedly connected to the inner side of the tube cover 802, and an air intake assembly 9 includes an air supply pipe 901 threadedly connected to the tube cover 802 and the outer side of the filter tube 801, an air intake hopper 902 is fixedly connected to the other side of the air supply pipe 901; the device is started by the control panel 3, the compression device 2 and the graded compression mechanism 5 start to work, air is sucked in from the air intake hopper 902, and the air is transported to the inside of the air supply pipe 901.

[0034] like Figures 2 to 6As shown, the silencer assembly 12 is used to eliminate the noise generated when the air is inhaled. The silencer assembly 12 is connected to the air intake assembly 9. The silencer assembly 12 includes an outer ring 1201 fixedly connected to the inner side of the air supply pipe 901, and the inner side of the outer ring 1201 is fixedly connected to an inner plate 1202. The inner side of the inner plate 1202 is provided with air vents 1203. There are seven silencer assemblies 12, which are evenly distributed on the inner side of the air supply pipe 901. The connection between the outer ring 1201 and the inner plate 1202 is an arc shape concave inward, and the diameter of the inner plate 1202 gradually decreases toward the side close to the air intake scoop 902.

[0035] After the air enters the air pipe 901, it contacts the inner plate 1202. Part of the air flows directly through the vent 1203, and the other part is blocked by the inner plate 1202. Part of the blocked air flows along the outer ring 1201, and the other part flows along the inner plate 1202, and then flows through the vent 1203. The air flowing through the vent 1203 needs to fill the large space after entering the large space from the small space, so that the air flow rate is reduced, reducing the noise generation, and then flows through multiple silencer components 12 in turn, and through the cavity formed between the silencer components 12, the air flow rate and impact kinetic energy are buffered, the gathered air is dispersed, and through the resonance effect between the multiple cavities, the noise and kinetic energy are further reduced. Through the cooperation between the silencer component 12 and the air pipe 901, the noise generation is greatly reduced.

[0036] like Figures 1 to 5 As shown, the filter assembly 8 includes a mounting tube 804 threadedly connected to the inner side of the compressed air pipe 6, a filter tube 801 is fixedly connected to the other side of the mounting tube 804, a tube cover 802 is threadedly connected to the other side of the filter tube 801, a filter plate 803 is fixedly connected to the inner side of the tube cover 802, threads are provided on the outer sides of the mounting tube 804 and the tube cover 802, and on the outer side of the filter tube 801 near the tube cover 802, anti-slip sleeves are fixedly connected to the outer sides of the filter tube 801 and the air supply pipe 901, a filter element is placed inside the filter tube 801, a transport pipe 7 is fixedly connected to the side of the compressed air pipe 6 away from the filter assembly 8, the other side of the transport pipe 7 is fixedly connected to the top of the air storage tank 1, a guardrail 11 is fixedly connected to one side of the air storage tank 1, a fan 10 is rotatably connected to the side of the compression device 2 near the guardrail 11, a leather ring is provided on the outer side of the fan 10, and the fan 10 and the motor 4 are transmission-connected via the leather ring.

[0037] The air passing through the silencer assembly 12 and the air intake assembly 9 enters the filter assembly 8, is first filtered by the filter plate 803, and then enters the filter tube 801, and is filtered by the filter element for the second step to filter out dust and other debris in the air. The air then passes through the compressed air pipe 6 to enter the graded compression mechanism 5 and the compression device 2 for compression processing, and then the compressed air passes through the transport pipe 7 to enter the air storage tank 1. While compressing the air, the motor 4 drives the fan 10 to rotate through the leather ring to dissipate heat from the compression device 2 and the graded compression mechanism 5, thereby completing the work.

[0038] The working principle provided by the utility model is as follows: the device is started by the control panel 3, the compression device 2 and the graded compression mechanism 5 start to work, air is sucked in from the air inlet 902, and the air is transported to the inside of the air delivery pipe 901. After the air enters the inside of the air delivery pipe 901, it contacts the inner plate 1202, part of the air flows directly through the vent 1203, and the other part is blocked by the inner plate 1202. Part of the blocked air flows along the outer ring 1201, and the other part flows along the inner plate 1202, and then flows through the vent 1203. After the air flowing through the vent 1203 enters the large space from the small space, it needs to fill the large space, so that the air flow rate is reduced, the noise generation is reduced, and then it flows through the multiple silencer components 12 in sequence, and passes through the silencer. The cavity formed between the sound components 12 buffers the flow rate and impact kinetic energy of the air, disperses the gathered air, and further reduces the noise and kinetic energy through the resonance effect between multiple cavities. The air passing through the silencer component 12 and the air intake component 9 enters the filter component 8, is first initially filtered by the filter plate 803, and then enters the filter tube 801. The second step of filtering by the filter element filters out dust and other debris in the air, and then the air enters the graded compression mechanism 5 and the compression device 2 through the compressed air pipe 6 for compression processing, and then the compressed air enters the air storage tank 1 through the transport pipe 7. While compressing the air, the motor 4 drives the fan 10 to rotate through the leather ring to dissipate heat from the compression device 2 and the graded compression mechanism 5, thereby completing the work.

[0039] The above compression device 2 and the graded compression mechanism 5 in the present utility model are both disclosed in the prior art and will not be described in detail here.

In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0041] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
