[0045] Please refer to Figures 1 to 10 The air compressor 1 and compressed gas providing device of the present application are shown, and the compressed gas providing device includes an air storage tank 10 for storing compressed gas, an air outlet pipeline device 2 for conveying compressed gas, and a pressure regulating valve 3. The pressure regulating valve 3 is used to adjust the air pressure of the compressed gas output by the air outlet pipeline device 2. The air outlet pipeline device 2 includes a foreign matter blocking component 20 for blocking foreign matter. The pressure regulating valve 3 is located downstream of the foreign matter blocking component 20. The air outlet pipeline device 2 is connected to the air storage tank 10. The compressed gas in the air storage tank 10 can be output to the outside through the air outlet pipeline device 2. During the process of the compressed gas in the air storage tank 10 being output through the air outlet pipeline device 2, it flows through the foreign matter blocking component 20 and the pressure regulating valve 3 in sequence. Based on the present technical solution, even if there may be foreign matter such as debris and residues in the gas tank 10 (for example, residues from the manufacturing process of the gas tank 10 or accumulated during subsequent use), the presence of the foreign matter blocking component 20 can play a certain degree of isolation and barrier effect on the foreign matter, thereby increasing the difficulty of foreign matter (especially larger foreign matter) being carried to the downstream of the foreign matter blocking component 20 along with the external output of the compressed gas in the gas tank 10, thereby invading the components downstream of the foreign matter blocking component 20 (for example, the pressure regulating valve 3), inhibiting the pressure regulating valve 3 from being invaded by foreign matter, thereby reducing the probability of the pressure regulating valve 3 malfunctioning, which is conducive to preventing the pressure regulating valve 3 from malfunctioning due to foreign matter over a longer period of use, promoting the normal use of the compressed gas providing device (especially the pressure regulating valve 3) over a longer period of use, and reducing customer complaints.

[0046] The foreign matter blocking component 20 is provided with a plurality of through holes 200 for the compressed gas to pass through, and the compressed gas in the gas storage tank 10 flows through the plurality of through holes 200 during the process of being output through the gas outlet pipe device 2. Furthermore, when the compressed gas outputted from the gas storage tank 10 flows through the foreign matter blocking component 20, it flows into the foreign matter blocking component 20 from the plurality of through holes 200. With such a design, foreign matter such as debris and residue needs to pass through the through holes 200 before entering the foreign matter blocking component 20, and it is relatively difficult for foreign matter such as debris and residue in the gas storage tank 10 to enter the foreign matter blocking component 20.

[0047] The foreign object blocking component 20 is also provided with a first air vent 201 through which compressed gas can pass. The compressed gas in the gas tank 10 flows through the first air vent 201 during the process of being output through the gas outlet pipeline device 2; further, the multiple through holes 200 are located upstream of the first air vent 201, so that the compressed gas in the gas tank 10 flows through the multiple through holes 200 and the first air vent 201 in sequence during the process of being output through the gas outlet pipeline device 2; when the compressed gas output by the gas tank 10 flows through the foreign object blocking component 20, it flows into the foreign object blocking component 20 through the multiple through holes 200 and flows out of the foreign object blocking component 20 through the first air vent 201. With such a design, foreign matter such as debris and residues need to pass through the upstream through holes 200 before entering the foreign matter blocking component 20, thereby increasing the difficulty for foreign matter such as debris and residues in the gas tank 10 to enter the foreign matter blocking component 20, and helping to reduce the probability of foreign matter such as debris and residues in the gas tank 10 being carried to the pressure regulating valve 3 by the compressed gas, causing the pressure regulating valve 3 to malfunction.

[0048] The foreign matter blocking component 20 is provided with a non-open end 202 and an open end 203 through which compressed gas can pass. The open end 203 and the non-open end 202 constitute the opposite ends of the foreign matter blocking component 20. The foreign matter blocking component 20 is in a tubular shape with one end open and the other end non-open. The plurality of through holes 200 are at least partially opened on the tube wall of the foreign matter blocking component 20, and the open end 203 forms a first vent 201. Such a design increases the difficulty of foreign matter such as debris and residue in the gas storage tank 10 passing through the foreign matter blocking component 20 to a certain extent. The open end 203 is relatively close to the pressure regulating valve 3 and the non-open end 202 is relatively far away from the pressure regulating valve 3; further, the plurality of through holes 200 are at least partially opened on the tube wall connecting the non-open end 202 and the open end 203 of the foreign matter blocking component 20.

[0049] In this embodiment, the non-open end 202 can be completely closed, and the non-open end 202 is located inside the gas tank 10, and the plurality of through holes 200 are all opened on the tube wall connecting the non-open end 202 and the open end 203 of the foreign matter blocking component 20. Such a design is conducive to increasing the difficulty of foreign matter such as debris and residues in the gas tank 10 entering the foreign matter blocking component 20 through the plurality of through holes 200, so that the foreign matter blocking component 20 is conducive to blocking foreign matter such as debris and residues in the gas tank 10 inside the gas tank 10.

[0050] The foreign object blocking component 20 is in the shape of a straight tube with one end open and the other end non-open; the non-open end 202 constitutes one end in the length direction of the foreign object blocking component 20; at least a portion of the multiple through holes 200 are exposed inside the gas tank 10, which is beneficial for the compressed gas in the gas tank 10 to pass through the through holes 200 more smoothly when the compressed gas is output to the outside; the non-open end 202 constitutes one end in the length direction of the foreign object blocking component 20; the non-open end 202 is located inside the gas tank 10, and the non-open end 202 is not convenient for foreign objects to pass through; such a design is beneficial to taking into account both the air permeability of the foreign object blocking component 20 to the compressed gas and the blocking ability to foreign objects in the gas tank 10.

[0051] In this embodiment, the multiple through holes 200 are evenly distributed in 4 rows on the tube wall of the foreign object blocking component 20, and each row of through holes 200 has 6 through holes 200; the total ventilation area of ​​the multiple through holes 200 is larger than the ventilation area of ​​the first air vent 201, and the ventilation area of ​​a single through hole 200 is between 1.7 square millimeters and 5.0 square millimeters, which is much smaller than the ventilation area of ​​the first air vent 201.

[0052] The air outlet pipeline device 2 also includes a connecting joint 21 arranged on the gas storage tank 10, the connecting joint 21 is fixed on the tank wall of the gas storage tank 10, and the foreign matter blocking component 20 is arranged on the connecting joint 21. Such a design makes it convenient to set the foreign matter blocking component 20 close to the gas storage tank 10.

[0053] The foreign matter blocking component 20 partially extends out of the connection joint 21, the plurality of through holes 200 are located upstream of the connection joint 21, and at least a portion of the plurality of through holes 200 are located outside the connection joint 21 and exposed inside the gas storage tank 10. Since the compressed gas outputted from the gas storage tank 10 flows into the foreign matter blocking component 20 through the plurality of through holes 200 when passing through the foreign matter blocking component 20, such a design based on this is conducive to taking into account both the air permeability of the foreign matter blocking component 20 to the compressed gas and the blocking ability of the foreign matter blocking component 20 to block the foreign matter in the gas storage tank 10 from entering the foreign matter blocking component 20, and is conducive to the foreign matter blocking component 20 to block the foreign matter in the gas storage tank 10 close to the gas storage tank.

[0054] The foreign object blocking component 20 is used to block foreign objects in the gas tank 10 from coming out of the gas tank 10. Furthermore, the foreign object blocking component 20 is used to block foreign objects in the gas tank 10 from coming out of the gas tank 10 along with the external output of compressed gas in the gas tank 10. A portion of the foreign object blocking component 20 is completely located outside the connecting joint 21, and the portion of the foreign object blocking component 20 is completely located inside the gas tank 10. The multiple through holes 200 are all opened on the portion of the foreign object blocking component 20, and the portion of the foreign object blocking component 20 is in a suspended state inside the gas tank 10. Since the compressed gas output by the gas tank 10 flows into the foreign object blocking component 20 through the multiple through holes 200 when passing through the foreign object blocking component 20, it is designed on this basis that the compressed gas is relatively easy to flow into the foreign object blocking component 20 through the multiple through holes 200 on the suspended part of the foreign object blocking component 20, but foreign objects usually move along the inner wall of the gas tank 10, and are relatively difficult to enter the foreign object blocking component 20 through the multiple through holes 200 on the suspended part of the foreign object blocking component 20, thereby promoting the foreign object blocking component 20 to more effectively block foreign objects in the gas tank 10.

[0055] The compressed gas in the gas tank 10 flows through the open end 203 during the process of being output through the gas outlet pipeline device 2. Furthermore, the compressed gas output by the gas tank 10 flows out of the foreign object blocking component 20 from the open end 203 when flowing through the foreign object blocking component 20. The non-open end 202 is located outside the connecting joint 21 and inside the gas tank 10, and the open end 203 is located inside the connecting joint 21.

[0056] The foreign matter blocking component 20 is fixed to the connecting joint 21 . Optionally, the foreign matter blocking component 20 is fixed to the connecting joint 21 by interference fit with the connecting joint 21 . Furthermore, the open end 203 is interference fit with the connecting joint 21 .

[0057] The non-open end 202 constitutes one end of the foreign body blocking component 20 in the length direction. The foreign body blocking component 20 is in the shape of a straight tube with one end open and the other end non-open. An outer flange portion 2030 is provided on the outer periphery of the open end 203. An inner flange portion 210 is provided on the inner periphery of the connecting joint 21. The inner flange portion 210 is located at one end of the connecting joint 21. The inner flange portion 210 is used to block the outer flange portion 2030 to prevent the foreign body blocking component 20 from escaping from the air inlet joint toward the inside of the gas storage tank 10. The foreign body blocking component 20 is provided with a plurality of Through holes 200, when the compressed gas output by the gas storage tank 10 flows through the foreign object blocking component 20, it flows into the foreign object blocking component 20 through the multiple through holes 200 and flows out of the foreign object blocking component 20 from the open end 203, at least a part of the multiple through holes 200 are opened on the tube wall connecting the non-open end 202 and the outer flange part 2030 of the foreign object blocking component 20, further, all of the multiple through holes 200 are opened on the tube wall connecting the non-open end 202 and the outer flange part 2030 of the foreign object blocking component 20.

[0058] The foreign object blocking component 20 can be made of metal or plastic. In the present embodiment, the gas tank 10 is a metal tank (such as a common steel tank), and welding slag remains in the gas tank 10. Based on the existence of the foreign object blocking component 20 of the present design, it is more difficult for foreign objects such as welding slag in the gas tank 10 to pass through the foreign object blocking component 20 along with the output of compressed gas, which is beneficial to inhibit foreign objects such as welding slag from invading components downstream of the foreign object blocking component 20.

[0059] The pressure regulating valve 3 includes a sealing core 30, which is located downstream of the foreign body blocking component 20. When the sealing core 30 is in the sealing position (see Figure 6 , at this time, the sealing core 30 closes the second vent 310), and under the blocking of the sealing core 30, the part of the outlet pipeline device 2 located upstream of the pressure regulating valve 3 is not connected with the part of the outlet pipeline device 2 located downstream of the pressure regulating valve 3; the sealing core 30 can leave the sealing position so that the part of the outlet pipeline device 2 located upstream of the pressure regulating valve 3 is connected with the part of the outlet pipeline device 2 located downstream of the pressure regulating valve 3, and then the compressed gas can flow from the part of the outlet pipeline device 2 located upstream of the pressure regulating valve 3 to the part of the outlet pipeline device 2 located downstream of the pressure regulating valve 3, so as to supply gas to the outside. The foreign matter blocking component 20 suppresses the probability of foreign matter such as debris and residue in the gas storage tank 10 moving to the sealing core 30 along with the compressed gas to a certain extent, which is conducive to suppressing the sealing core 30 from malfunctioning (such as weakened sealing) due to foreign matter such as debris and residue in the gas storage tank 10. The sealing core 30 can be made of a flexible material (such as rubber). For the present patent application, upstream and downstream refer to the output flow direction of the compressed gas in the gas storage tank 10 .

[0060] The pressure regulating valve 3 also includes a second vent 310 corresponding to the sealing core 30, and the foreign matter blocking component 20 is located upstream of the second vent 310. The second vent 310 is used to connect the part of the outlet pipeline device 2 located upstream of the pressure regulating valve 3 with the part of the outlet pipeline device 2 located downstream of the pressure regulating valve 3; when the sealing core 30 is in the sealing position, the sealing core 30 closes the second vent 310, so that the part of the outlet pipeline device 2 located upstream of the pressure regulating valve 3 is not connected with the part of the outlet pipeline device 2 located downstream of the pressure regulating valve 3. Under such circumstances, the outlet pipe device 2 cannot deliver compressed gas; the sealing core 30 can leave the sealing position without closing the second vent 310; during the process of the compressed gas in the gas storage tank 10 being output through the outlet pipe device 2, it flows through the part of the outlet pipe device 2 upstream of the second vent 310 (equivalent to the part of the air pipe device 2 upstream of the pressure regulating valve 3), the second vent 310, and the part of the outlet pipe device 2 downstream of the second vent 310 (equivalent to the part of the air pipe device 2 upstream of the pressure regulating valve 3). The foreign matter blocking component 20 upstream of the second vent 310 inhibits or delays foreign matter such as debris and residue in the gas storage tank 10 to a certain extent from being brought to the vicinity of the second vent 310 and the sealing core 30 by the compressed gas, thereby inhibiting foreign matter from damaging the sealing performance between the second vent 310 and the sealing core 30.

[0061] The gas outlet pipeline device 2 includes a manifold 22, which is located downstream of the foreign matter blocking component 20. The pressure regulating valve 3 is assembled on the manifold 22. When the sealing core 30 is in the sealing position, the part of the manifold 22 located upstream of the pressure regulating valve 3 is not connected with the part of the manifold 22 located downstream of the pressure regulating valve 3 under the blocking of the sealing core 30; the sealing core 30 can leave the sealing position so that the part of the manifold 22 located upstream of the pressure regulating valve 3 is connected with the part of the manifold 22 located downstream of the pressure regulating valve 3. The foreign matter blocking component 20 inhibits foreign matter such as debris and residue in the gas storage tank 10 from moving to the sealing core 30 along with the compressed gas to a certain extent, which is conducive to inhibiting the sealing core 30 from causing malfunction (such as weakened sealing) due to foreign matter such as debris and residue in the gas storage tank 10.

Furthermore, the reset spring 32 is used to reset the sealing core 30 to the closed position; based on the action of the reset spring 32, under normal circumstances (the air outlet pipeline device 2 does not deliver compressed gas to the outside), the sealing core 30 remains in the sealed position.

[0063] The compressed gas providing device also includes a first pressure gauge 11, and the air outlet pipeline device 2 also includes an air supply connector 23, which is fixedly connected to the manifold 22.

In the process of the compressed gas in the air storage tank 10 being output through the air outlet pipeline device 2, it flows through the foreign matter blocking component 20, the part of the manifold 22 upstream of the pressure regulating valve 3, the part of the manifold 22 downstream of the pressure regulating valve 3, and the air supply connector 23 in sequence.

The piston 413 can move in the first component 37 (the outer periphery of the piston 413 is sealed and fitted with the inner periphery of the first component 37). The threaded rod 330 of the pressure regulating knob 33 is threadedly connected to the first component 37. The threaded rod 330 can be adjusted by screwing the pressure regulating knob 33 to different angles. 30 is relative to the depth of the first component 37, so that the compression degree of the strong spring 36 can be adjusted, and then the output air pressure of the air outlet pipeline device 2 can be adjusted; the pressing cap 34 is pressed between the threaded rod 330 and the strong spring 36, and the convex column 350 of the piston 413 abuts the sealing core 30; when the air supply connector 23 does not release air to the outside, the sealing core 30 remains in the sealing position, and the pressing force of the strong spring 36 on the piston 413 is roughly equivalent to the pressure of the compressed gas on the piston 413; when the air supply connector 23 releases air to the outside, the outlet The internal air pressure of the portion of the air pipe device 2 downstream of the pressure regulating valve 3 is weakened, so that the pressure of the compressed gas on the piston 413 is weakened, and the pressure of the strong spring 36 on the piston 413 will cause the piston 413 (the boss 350) to push the sealing core 30 away from the sealing position, and then the compressed gas output from the gas storage tank 10 flows through the portion of the air outlet pipe device 2 upstream of the pressure regulating valve 3, the second vent 310, the portion of the air outlet pipe device 2 downstream of the pressure regulating valve 3, and the air supply connector 23. The pressure regulating knob 33 is also provided with a stop ring 331 clamped or fixed on the threaded rod 330, and the stop ring 331 is used to prevent the pressure regulating knob 33 from being directly screwed off from the second component 31.

The connection joint 21 is fixed to the tank wall of the gas tank 10, and the foreign matter blocking component 20 is fixed to the connection joint 21, so that the foreign matter blocking component 20 can be conveniently and effectively arranged near the gas tank 10, and it is also convenient for the foreign matter blocking component 20 to block foreign matter in the gas tank 10 near the gas tank 10; during the process of the compressed gas in the gas tank 10 being output through the gas outlet pipeline device 2, it flows through the connection joint 21, the part of the manifold 22 located upstream of the pressure regulating valve 3, the part of the manifold 22 located downstream of the pressure regulating valve 3, and the gas supply joint 23 in sequence.

[0066] The foreign object blocking component 20 is at least partially accommodated in the gas storage tank 10, and the air outlet pipeline device 2 also includes a hose component 24 with joints at opposite ends. The hose component 24 is located upstream of the manifold component 22, and the joint 240 at one end of the hose component 24 is fixedly connected to the manifold component 22.

The compressed gas providing device also includes a second pressure gauge 14, which is arranged on the manifold 22. The second pressure gauge 14 monitors the internal air pressure of the part of the manifold 22 upstream of the pressure regulating valve 3. The part of the manifold 22 upstream of the pressure regulating valve 3 is maintained in communication with the interior of the gas storage tank 10. The internal air pressure of the part of the manifold 22 upstream of the pressure regulating valve 3 is equal to the air pressure in the gas storage tank 10. The second pressure gauge 14 indirectly monitors the air pressure in the gas storage tank 10 by monitoring the internal air pressure of the part of the manifold 22 upstream of the pressure regulating valve 3.

[0068] The air outlet pipeline device 2 also includes an adapter component 25, a connecting joint 21 is fixed on the tank wall of the gas storage tank 10, the adapter component 25 is fixedly connected to the connecting joint 21, a pressure switch 40 (to be described in detail later) is installed and fixed on the adapter component 25, and the pressure switch 40 can be operated based on the internal air pressure of the adapter component 25 (that is, turn on or off the air pump 41, which will be described in detail later), the first pressure gauge 11 is threadedly connected and fixed to the third interface part 223 of the manifold component 22, the second pressure gauge 14 is threadedly connected and fixed to the fourth interface part 224 of the manifold component 22, and the air supply connector 23 is threadedly connected and fixed to the fifth interface part 225 of the manifold component 22. The air supply connector 23 can adopt a quick connector, which is a mature and common component (the specific structure and working principle are not repeated here), and can be quickly connected to the outside. For example, the air outlet pipeline device 2 can be quickly connected to the connector of the air pipeline of a pneumatic tool (such as a pneumatic drill, a pneumatic nailer, etc.) through a quick connector to output compressed gas to the pneumatic tool, and the operation of the pneumatic tool is driven by the compressed gas.

[0069] The air supply connector 23 is located downstream of the manifold 22, and the hose component 24 is located upstream of the manifold 22. The hose component 24 is indirectly connected to the connecting connector 21 through the adapter component 25. The connector 240 at one end of the hose component 24 is fixedly connected to the manifold 22, and the connector 241 at the opposite end of the hose component 24 is fixedly connected to the adapter component 25.

The tenth interface portion 253, the ninth interface portion 252, the eighth interface portion 251, and the seventh interface portion 250 are all connected. A plurality of first vents 17 are provided inside the adapter component 25. These vents are used for communication between the tenth interface portion 253, the ninth interface portion 252, the eighth interface portion 251, and the seventh interface portion 250. These first vents 17 are also helpful in preventing foreign matter from passing through. The air outlet pipe device 2 can also eliminate the hose component 24 and the adapter component 25 between the manifold component 22 and the connecting joint 21, and directly fix the manifold component 22 to the connecting joint 21.

[0070] In addition to the aforementioned compressed gas providing device, the air compressor 1 also includes an air pump 41 and an air intake pipeline device 42. The air pump 41 is used to compress air to produce compressed gas. The air intake pipeline device 42 is connected between the air pump 41 and the gas storage tank 10 to transport the compressed gas produced by the air pump 41 to the gas storage tank 10 for storage.

[0071] The adapter component 25 is also provided with a second vent hole 18 corresponding to the pressure switch 40. The compressed gas inside the adapter component 25 passes through the second vent hole 18 and acts on the pressure switch 40, so that the pressure switch 40 can be operated based on the internal air pressure of the adapter component 25. The pressure switch 40 is a part of the air compressor 1. The pressure switch 40 is used to turn on and off the air pump 41. Further, the pressure switch 40 can turn on and off the air pump 41 by turning on and off the power supply of the air pump 41. The pressure switch 40 is arranged on the air outlet pipeline device 2. The specific situation in which the pressure switch 40 can be actuated based on the size of the internal air pressure of the adapter component 25 can be: the pressure switch 40 automatically opens or closes the air pump 41 based on the internal air pressure of the portion of the air outlet pipeline device 2 upstream of the pressure regulating valve 3 (equal to the internal air pressure of the adapter component 25), with the goal of keeping the air pressure in the air storage tank 10 (the air pressure in the air storage tank 10 is equal to the internal air pressure of the portion of the air outlet pipeline device 2 upstream of the pressure regulating valve 3) within a predetermined air pressure range; the air pump 41 works to produce compressed gas, and as the compressed gas produced by the air pump 41 is continuously transported to the air storage tank 10 for storage via the air inlet pipeline device 42, the air pressure in the air storage tank 10 continues to rise. When the internal air pressure of the portion of the outlet pipe device 2 upstream of the pressure regulating valve 3 (equal to the air pressure in the air storage tank 10) rises to the upper limit of the predetermined air pressure range, the pressure switch 40 cuts off the power supply of the air pump 41 and turns off the air pump 41; when the internal air pressure of the portion of the outlet pipe device 2 upstream of the pressure regulating valve 3 drops to the lower limit of the predetermined air pressure range, the pressure switch 40 connects the power supply of the air pump 41 and turns on the air pump 41, until the internal air pressure of the portion of the outlet pipe device 2 upstream of the pressure regulating valve 3 rises to the upper limit of the predetermined air pressure range again, the pressure switch 40 cuts off the power supply of the air pump 41 again and turns off the air pump 41, and repeats the above process, so that the air pressure in the air storage tank 10 is dynamically maintained within the predetermined air pressure range. The air pressure in the air storage tank 10 is the air pressure of the compressed gas in the air storage tank 10.

[0072] The air pump 41 includes a motor 410, a cylinder 411, a cylinder head 412, a piston 413, a connecting rod, and an exhaust chamber 414. The intake pipe device 42 is connected between the exhaust chamber 414 of the air pump 41 and the air storage tank 10. The cylinder head 412 defines at least a portion of the exhaust chamber 414. When the motor 410 is running, the piston 413 can be driven to reciprocate in the cylinder 411 through the connecting rod, so that the piston 413 compresses the air flowing into the cylinder 411 to produce compressed gas. The compressed gas is pressed into the exhaust chamber 414 by the piston 413 and is further transported to the air storage tank 10 for storage via the intake pipe device 42. The air pump 41 and the pressure switch 40 are both mature and common components, and the specific structure and working principle will not be further described here.

[0073] The air compressor 1 also includes a foreign object blocking component 43 corresponding to the air intake pipeline device 42. The foreign object blocking component 43 is in the shape of a straight tube with one end open and the other end closed. A plurality of through holes for ventilation and blocking foreign objects are provided on the tube wall between the opposite ends of the foreign object blocking component 43. The foreign object blocking component 43 and the foreign object blocking component 20 are components with basically the same structure. The main difference is that the foreign object blocking component 20 is arranged on the air outlet pipeline device 2, while the foreign object blocking component 43 is arranged on the air intake pipeline device 42; the air intake pipeline device 42 also includes a one-way valve 420, which is used for the one-way gas supply of the air supply pipeline device to the air storage tank 10. The compressed gas transported by the air intake pipeline device 42 passes through the one-way valve 420 and the foreign object blocking component 43 in turn and enters the air storage tank 10 for storage. The foreign matter blocking component 43 is used to prevent foreign matter in the gas tank 10 from splashing onto the one-way valve 420 of the intake pipe device 42 along with the disturbance of the compressed gas in the gas tank 10, so as to delay or inhibit the one-way valve 420 from being invaded by foreign matter and causing the sealing performance of the one-way valve 420 to be weakened or even fail.

[0074] The air compressor 1 further includes a fixing bracket 44 and a panel member 45 fixed on the fixing bracket 44 . The manifold member 22 is fixed on the panel member 45 by screws 46 . The panel member 45 is fixed on the fixing bracket 44 . The fixing bracket 44 is fixed to the gas storage tank 10 by welding.

[0075] The air compressor 1 also includes a pressure relief pipeline device 47 corresponding to the air intake pipeline device 42. The pressure relief pipeline device 47 is connected between the air intake pipeline device 42 and the pressure switch 40. The pressure switch 40 also has a pressure relief function. When the internal air pressure of the part of the air outlet pipeline device 2 upstream of the pressure regulating valve 3 (equal to the air pressure in the air storage tank 10) rises to the upper limit of the predetermined air pressure range so that the pressure switch 40 closes the air pump 41, the pressure switch 40 also connects the pressure relief pipeline device 47 with the external environment, thereby unloading the compressed gas in the pressure relief pipeline device 47, the air intake pipeline device 42, and the exhaust chamber 414, so that the air pump 41 can be started without load the next time it is started, making it easier to start the air pump 41.
