[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] The following disclosure provides many different embodiments or examples for implementing different solutions of the present invention.

[0036] Reference Figures 1 to 5 As shown, an air supply device includes an air intake component 1, an air storage tank 2 and a controller 3. The air intake component 1 includes an air compressor 11. The air compressor 11 supplies air to the air storage tank 2. The air storage tank 2 is provided with an air outlet, and air is supplied to the stage equipment through the air outlet;

[0037] The air storage tank 2 is connected with a pressure sensor 4 and a first pressure relief valve 5. The pressure sensor 4 is used to monitor the pressure of the air storage tank 2. The air compressor 11, the pressure sensor 4 and the first pressure relief valve 5 are respectively connected with the controller 3. The first preset value is greater than the second preset value, and the second preset value is greater than the third preset value.

[0038] When the pressure of the gas storage tank 2 is higher than the first preset value, it is determined that the gas storage tank 2 has reached the maximum bearing pressure, and the first pressure relief valve 5 releases the pressure to prevent the gas storage tank 2 from being damaged;

[0039] When the pressure of the gas storage tank 2 is higher than the second preset value, it is judged that the gas storage tank 2 has reached a sufficient gas supply level, and the air compressor 11 stops working to prevent the pressure in the gas storage tank 2 from being too high;

[0040] When the pressure of the gas storage tank 2 is lower than the third preset value, it is determined that the gas storage capacity of the gas storage tank 2 is insufficient, and the air compressor 11 works to supply gas to the gas storage tank 2;

[0041] This achieves intelligent gas supply, reduces manual operation, and can continuously supply gas to stage equipment.

[0042] In this embodiment, the air intake assembly 1 is provided with two;

[0043] When the pressure of the gas storage tank 2 is lower than the fourth preset value, it is determined that the gas storage tank 2 is seriously short of gas, and both air compressors 11 work to increase the gas supply speed;

[0044] When the pressure of the gas storage tank 2 is greater than the fourth preset value and less than the third preset value, it is determined that the gas shortage is moderate at this time, and only one of the air compressors 11 can be operated, thereby reducing energy consumption and saving resources while ensuring gas supply.

[0045] In another embodiment, it can also be configured that when the pressure of the air storage tank 2 is less than the third preset value, both air compressors 11 work, and the two air compressors 11 work synchronously, which is relatively simple to control.

[0046] In this embodiment, a machine base 6 is also included, in which the air intake assembly 1, the air storage tank 2 and the controller 3 are all arranged. The machine base 6 is provided with an air inlet 61 and a pneumatic quick connector 7, and the air outlet is connected to the pneumatic quick connector 7. The pneumatic quick connector 7 is used to connect with the stage equipment, which is convenient and fast; and the machine base 6 is movable, and a universal wheel is provided at the bottom of the machine base 6, so that the air supply machine can be moved at will to supply air to the stage equipment.

[0047] The pneumatic quick connector 7 is preferably a three-way quick connector, which can be connected to multiple air pipes and can supply air to multiple stage equipment at the same time.

[0048] In this embodiment, the air intake assembly 1 includes a filter 12 and a boost valve 13, the filter 12 is connected to the input end of the air compressor 11, the output end of the air compressor 11 is connected to the air storage tank 2 through a first pipeline, and the boost valve 13 is connected to the first pipeline;

[0049] The filter 12 can filter the air. The air filtered by the filter 12 enters the air compressor 11 , is compressed by the air compressor 11 , and then is pressurized by the boost valve 13 and enters the air storage tank 2 .

[0050] In this embodiment, a second pressure relief valve 8 is connected to the first pipeline, and the second pressure relief valve 8 is connected to the controller 3. When the pressure provided by the boost valve 13 is too large, or the gas storage tank 2 reaches a first preset value, the second pressure relief valve 8 can be opened to release the gas.

[0051] In this embodiment, a soundproof chamber 9 is provided in the base 6, and the boost valve 13 is arranged in the soundproof chamber 9. When the boost valve 13 is in operation, the noise is relatively large, and the soundproof chamber 9 is used to reduce the noise of the boost valve 13.

[0052] In this embodiment, the sound insulation chamber 9 is provided with an air vent 91, and a first cooling fan 92 is provided outside the sound insulation chamber 9. The first cooling fan 92 allows the air in the sound insulation chamber 9 to circulate with the air in the base 6, thereby dissipating the heat of the sound insulation chamber 9 and dissipating the heat generated by the boost valve 13 in time.

[0053] Moreover, sound insulation cotton is provided on one side of the air vent 91 located inside the sound insulation chamber 9 . The sound insulation cotton will not affect the circulation of gas, but can further reduce the noise generated by the boost valve 13 .

[0054] In this embodiment, an exhaust port 62 is provided on the base 6, and a second cooling fan 63 is provided in the base 6. The second cooling fan 63 allows the air in the base 6 to circulate with the outside to dissipate the heat of the base 6 and discharge the heat generated by the air compressor 11 in time to avoid overheating of the air compressor 11. Of course, the exhaust port 62 and the air inlet 61 can be provided with sound insulation cotton to reduce the noise generated by the base 6.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
