[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] like Figures 1-9 As shown, the utility model discloses an air compressor, including a compression host 1, an air extraction module located in the compression host 1, and an air storage tank assembly 2. The air storage tank assembly 2 includes an air storage tank 21 and an adapter 23 located on the air storage tank 21. The axial direction of the air storage tank assembly 2 extends up and down. The air extraction module includes a cam 13, a connecting rod 12, a piston that moves up and down in linkage with the connecting rod 12, and a driving member 11 (usually a motor). External gas can enter the compression host 1 and then rotate the driving member 11, so that the output shaft 111 on the driving member 11 drives the cam 13 to rotate and drives the connecting rod 12 to swing. The cam 13 is eccentrically connected to the output shaft 111 and the connecting rod 12 is sleeved with the cam 13. As each connecting rod 12 swings, it can drive each piston (not shown in the figure) to reciprocate up and down, thereby realizing suction and making the compressed gas flow to the air storage tank assembly 2. By connecting the pipe of the object to be inflated to the adapter 23, In order to achieve the output of compressed air (this is the prior art and will not be described in detail here), the compressor main unit 1 also includes a gripping portion 3 located above the compressor main unit 1, and the compressor main unit 1 includes two mating covers 18, each mating cover 18 is located above the corresponding side piston, and each mating cover 18 is installed with a connecting cover 14 by bolts, and a connecting pipe (not shown in the figure) is installed between each connecting cover 14, and each connecting cover 14 is detachably connected to the gripping portion 3 by bolts, snaps, etc. The design of the gripping portion 3 can reduce the need for maintenance due to accidental damage during transportation, thereby reducing the maintenance cost of the equipment, and moving the compressor main unit 1 by the gripping portion 3 can reduce potential damage to the equipment due to improper transportation. When repairing and maintaining the air compressor, maintenance personnel may need to frequently move the compressor main unit 1 to better access internal components. The gripping portion 3 allows maintenance personnel to more easily adjust the position of the compressor main unit 1.

[0031] Among them, the gripping part 3 includes a front shell 31 and a rear shell 32, and the front shell 31 and the rear shell 32 are detachably connected by bolts, snaps, etc. A front gripping groove 311 is provided in the middle of the front shell 31, and a rear gripping groove 321 is provided in the middle of the rear shell 32. The front gripping groove 311 and the rear gripping groove 321 have the same shape, and the front gripping groove 311 includes a plurality of gripping blocks 312, and each gripping block 312 is arranged in an arc shape with the opening facing upward. Since the front shell 31 and the rear shell 32 are detachably connected, the gripping part 3 can be divided into two parts as a component before it is installed in the air compressor, further reducing the space occupied when stored, and since there are gripping grooves and gripping blocks 312 on both the front gripping part 3 and the rear gripping part 3, it is more in line with human ergonomics when holding, providing better holding comfort and operating experience.

[0032] Among them, the front shell 31 is provided with a positioning plug 314 protruding circumferentially toward the rear, and the rear shell 32 is provided with a positioning slot 322 corresponding to the positioning plug 314. When the front shell 31 and the rear shell 32 are connected together to realize the assembly of the gripping part 3, the positioning plug 314 of the front shell 31 will enter the positioning slot 322 of the rear shell 32, thereby determining the relative positions of the two.

[0033] Among them, the front shell 31 is provided with a plurality of positioning posts 313 protruding toward the rear, and the rear shell 32 is provided with a positioning seat 323 corresponding to each positioning post 313, and each positioning seat 323 is provided with a positioning groove 3231 for inserting the positioning post 313. During the installation process of the front shell 31 and the rear shell 32, since each positioning post 313 will be inserted into the positioning groove 3231 of the corresponding positioning seat 323, as the positioning post 313 completes the cooperation with the corresponding positioning groove 3231, the front shell 31 and the rear shell 32 will not be displaced during use, thereby providing convenience for the subsequent fixation of the two.

[0034] Preferably, each of the connecting covers 14 includes a mounting groove 141 on the rear side and a pressure plate 142 located above the mounting groove 141, and the rear shell 32 includes a mounting section 324 made of rubber or other easily deformable materials inserted into the mounting groove 141, and the mounting section 324 is located below the pressure plate 142. When the entire gripping portion 3 is installed above the connecting cover 14, the mounting section 324 on the rear shell 32 needs to be deformed by applying force and enters the mounting groove 141. At this time, after the mounting section 324 is abutted against the pressure plate 142, the relative relationship between the connecting cover 14 and the gripping section can be determined without the action of external force, so that the gripping section cannot move up and down compared to the connecting cover 14, thereby providing convenience for the fixation of the two.

[0035] In addition, the fan blades 1111 are fixedly installed on the output shaft 111 of the driving member 11 by means of key connection or the like, and the compression host 1 is provided with a baffle 15 on the outside of the fan blades 1111, and each of the baffles 15 is provided with a number of through slots 151. As the driving member 11 is started and the output shaft 111 rotates, in addition to the swinging of the connecting rod 12 to drive the piston to reciprocate up and down, the fan blades 1111 will rotate at the same time to dissipate heat for the driving member 11 and the compression host 1 in the process of achieving air flow and air intake. Since the driving member 11 will generate heat during operation and if the heat cannot be dissipated in time, the internal temperature of the driving member 11 will increase, and the high temperature will increase the thermal stress of the internal material of the driving member 11. This will accelerate the fatigue and aging of the material in the long run and shorten the service life of the driving member 11. Therefore, heat dissipation can extend the service life of the driving member 11.

[0036] Among them, the compression host 1 is provided with a plurality of heat dissipation fins 16 around the driving part 11. The design of the heat dissipation fins 16 significantly improves the heat dissipation capacity of the compression host 1, which helps to maintain the stability and performance of the machine during long-term operation.

[0037] In addition, the gas tank assembly 2 includes a left limit portion 24 and a right limit portion 25 located on the left and right sides of the gas tank 21, and the compressor main unit 1 includes a loading section 17 at the bottom. The length of the top of the loading section 17 is less than the length of the bottom and is arranged in a step-like manner. The right connecting portion is provided with a loading groove 241 corresponding to the loading section 17. Through the design of the left limit portion 24 and the right limit portion 25, the stability of the gas tank 21 located below the compressor main unit 1 is improved so that it will not move at will. At the same time, since the length of the bottom of the loading section 17 is greater than the top length, and the loading groove 241 is adapted to the shape of the loading section 17, the bottom of the loading section 17 will first enter the top of the loading groove 241 and force the two to cooperate downward. At this time, without the action of external force, the bottom of the loading section 17 is difficult to cross the top of the loading groove 241, thereby facilitating the fixation of the left limit portion 24, the right limit portion 25 and the compressor main unit 1, making it easy to move the air compressor.

[0038] In addition, a display screen 22 is provided on the front side of the gas storage tank 21. The display screen 22 is provided with a processor (this is a prior art and will not be described in detail here). The display screen 22 can be used to adjust the relevant data to be compressed, such as Figure 1The pressure setting, operating speed, etc. shown in the figure are as follows. The compressed air may bring in moisture during the compression process. If the moisture is not discharged in time, it will affect the quality of the compressed air, causing rust on pneumatic tools and pipeline components. It may also cause corrosion to equipment and pipelines, reduce the working efficiency of the air compressor, and affect product quality. A pressure sensor 212 and a pressure relief valve 211 are provided on one side of the gas storage tank 21. The pressure relief valve 211 is used to remove moisture in time to ensure gas quality, prevent rust, and extend the service life of the equipment. The pressure sensor is linked to the display screen (this is a prior art and will not be elaborated on here). In the air compressor system, the gas storage tank 21 plays a role. The function of storing compressed air is to ensure the stability and continuity of the air supply system. In order to ensure that the pressure in the air tank 21 is maintained within the set safe and effective working range, the pressure sensor 212 will monitor the pressure level in the air tank 21 in real time. According to the pressure value detected by the pressure sensor 212, the control system can perform corresponding operations, such as starting or stopping the air compressor to maintain the required pressure range. When the pressure in the air tank 21 drops below the preset lower limit, the control system will start the air compressor to inflate the air tank 21; on the contrary, if the pressure in the air tank 21 reaches the preset upper limit, the control system will command the air compressor to stop running to avoid overpressure.

[0039] In addition, the driving element 11 is a permanent magnet synchronous motor, which is driven by hardware of the FOC algorithm (this is existing technology and will not be described in detail here). Compared with the AC asynchronous motor, the permanent magnet synchronous motor can achieve higher efficiency due to its structural characteristics and the current required for starting is smaller than that of the AC asynchronous motor. This makes the air compressor more energy-efficient during operation and reduces long-term operating costs. Compared with AC asynchronous motors with the same output power, the permanent magnet synchronous motor is smaller in size and lighter in weight, which means that a more compact air compressor system can be designed, saving space and improving flexibility. In addition, the permanent magnet synchronous motor does not have wear parts such as brushes and commutators inside, so their maintenance requirements are low and their service life is long, reducing downtime and costs caused by maintenance.

[0040] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
