DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figure 1-3 The illustrated structure is a conveniently adjustable pressure difference air blowing cooling structure, comprising an air outlet pipe 1 and a pressure difference controller 3 installed at the left end of the air outlet pipe 1;

[0023] A solenoid valve 2 is provided inside the air outlet pipe 1 to control the wind force of the gas discharged from the air outlet pipe 1;

[0024] A compressor 9 is provided on the lower side of the pressure difference controller 3 to inhale air;

[0025] The right circular outer wall of the compressor 9 is fixedly connected with an air inlet pipe 10 to guide the air flow direction. When the gas is discharged outwards by the pressure difference method for cooling operation, the air is sucked in by the compressor 9 and guided to the pressure difference controller 3 to control the pressure difference. According to the demand, the solenoid valve 2 is controlled to make the gas outlet range inside the outlet pipe 1. The pressure of the exhaust gas is controlled by the pressure difference controller 3, and the exhaust gas is sprayed outwards through the outlet pipe 1 to the surface of the object to be cooled, and the cooling operation is performed;

[0026] A filter bin 11 is fixedly connected to the outer wall of the right end of the air intake pipe 10, and a filter plate b17 is fixedly connected between the inner walls of the upper and lower ends of the filter bin 11 near the right side to filter impurities in the air. A filter plate a13 is arranged on the left side of the filter plate b17 to block impurities that cannot be filtered by the filter plate b17. An air inlet 12 is fixedly connected to the outer wall of the right end of the filter bin 11 to guide the gas into the interior of the filter bin 11, and an air outlet 14 that runs through the left and right sides is provided inside the outer wall of the left end of the filter bin 11 to transport the filtered gas to the air intake pipe 10. When the compressor 9 inhales air, the air enters the filter bin 11 through the air inlet 12, and after impurities of different sizes are filtered and blocked by the filter plates b17 and filter plates a13 inside the filter bin 11, the air enters the air intake pipe 10 through the air outlet 14, and then the air is guided by the compressor 9.

[0027] like Figure 2 As shown, a pressure reducing net 16 is fixedly connected between the inner walls of the upper and lower ends of the filter bin 11 near the left side to reduce the flow velocity of the air, a guide block 15 is fixedly connected to the inner wall of the left end of the filter bin 11 to guide the air flow direction, and a slag discharge port 18 is opened on the right end outer wall of the filter bin 11 near the lower side, and the internal thread of the slag discharge port 18 is connected with a fixing bolt 19.

[0028] When air circulates through the filter bin 11, the air will pass through the pressure reducing net 16 to reduce the air circulation speed, so as to prevent the air from circulating too fast and causing the internal air pressure of the filter bin 11 to increase, resulting in the air being unable to circulate. The slag discharge port 18 can be leaked out by rotating the fixing bolt 19 counterclockwise, and the impurities blocked by the filter plates a13 and b17 in the filter bin 11 can be removed from the slag discharge port 18, so that the inside of the filter bin 11 can be kept clean. After cleaning, the fixing bolt 19 can be screwed back into the slag discharge port 18 in a clockwise manner.

[0029] like Figure 2 As shown, the filter chamber 11 and the air intake pipe 10 are fixedly connected by welding, and the mesh density of the filter plate a13 is smaller than the mesh density of the filter plate b17.

[0030] By welding, the air filtered by the filter chamber 11 can be directly transported into the air intake pipe 10 to avoid air leakage. The smaller mesh density of the filter plate a13 can block impurities that the filter plate b17 cannot block.

[0031] like Figure 1 As shown, the outer wall of the lower end of the pressure difference controller 3 is fixedly connected to an exhaust pipe a4, the other end of the exhaust pipe a4 is fixedly connected to a condenser 5 to reduce the temperature of the air, the other end of the condenser 5 is fixedly connected to an exhaust pipe b6, and the other end of the exhaust pipe b6 is fixedly connected to a muffler 7 to reduce the noise during air circulation.

[0032] After the compressor 9 sucks in air, it will transport the air to the muffler 7 through the connecting pipe 8 to reduce the sound of air circulation, and then transport it to the condenser 5 through the exhaust pipe b6 to cool the temperature of the air, thereby achieving the effect of cooling the temperature of other objects, and then transport it to the inside of the pressure difference controller 3 through the exhaust pipe a4 to wait for the air to be pressurized and discharged.

[0033] like Figure 1 As shown, a connecting pipe 8 is fixedly connected between the right end outer wall of the muffler 7 and the compressor 9 for gas circulation, and a porous sponge is arranged inside the muffler 7.

[0034] The connecting pipe 8 allows the air sucked in by the compressor 9 to stably enter the muffler 7 , and the porous structure of the porous sponge inside the muffler 7 can reduce the louder sound.

[0035] The implementation principle of this embodiment is: when the gas is discharged outwardly through the pressure difference method for cooling operation, the air is sucked in by the compressor 9 and guided to the pressure difference controller 3 to control the pressure difference, and according to the demand, the solenoid valve 2 is controlled to make the gas outlet range inside the outlet pipe 1, and the pressure of the exhaust gas is controlled by the pressure difference controller 3, and the gas is sprayed outward through the outlet pipe 1 onto the surface of the object to be cooled to perform a cooling operation. When the compressor 9 sucks in the air, the air will enter the filter bin 11 through the air inlet 12, and after the impurities of different sizes are filtered and blocked by the filter plates b17 and a13 inside the filter bin 11, the air will enter the intake pipe 10 through the air outlet 14, and then the air will be guided by the compressor 9.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
