DETAILED DESCRIPTION

[0021] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] The utility model embodiment discloses a modular vacuum generator, according to the attached Figure 1-4 As shown, it includes a generating unit 1, an installation unit 2 is arranged outside the generating unit 1, the generating unit 1 includes a shell 11, an air inlet 12 and a negative pressure air inlet 13, the air inlet 12 and the negative pressure air inlet 13 are respectively arranged on the side and bottom of the shell 11, and the top, bottom and both sides of the shell 11 are provided with installation holes 111;

[0023] The mounting unit 2 includes a mounting base 21, a threaded column 23, an adjusting sleeve 24 and a connecting head 25. The mounting base 21 is connected to the mounting hole 111 on one side of the shell 11, the end of the threaded column 23 is connected to the mounting base 21, and the adjusting sleeve 24 is threadedly connected to the outside of the other end of the threaded column 23, and the connecting head 25 is rotatably set on the end of the adjusting sleeve 24.

[0024] During use, the mounting base 21 can be fixed arbitrarily on the top, bottom and both sides of the shell 11 by utilizing the mounting holes 111 opened on the top, bottom and both sides of the shell 11. After the mounting base 21 is installed on the outside of the shell 11, the adjusting sleeve 24 can be rotated so that the adjusting sleeve 24 can move relative to the threaded column 23, thereby adjusting the distance between the connecting head 25 and the shell 11. At the same time, the connecting head 25 can be rotated relative to the adjusting sleeve 24, which makes it more convenient to connect the connecting head 25 with external equipment.

[0025] Furthermore, a cavity 15 is defined inside the housing 11 , a nozzle 121 is installed inside the cavity 15 , and an air inlet passage 122 is defined between the nozzle 121 and the air inlet 12 .

[0026] Furthermore, an air suction channel 131 is provided between the negative pressure air suction port 13 and the cavity 15 .

[0027] Furthermore, a silencer 14 is installed on the side of the shell 11 and an air outlet channel 141 is opened between the cavity 15 .

[0028] During use, an external nozzle is used to spray compressed air at high speed toward the air inlet 12. After the compressed air is ejected from the nozzle 121, a jet is formed in the cavity 15, generating a suction flow. Under the suction effect, the air around the nozzle outlet is continuously sucked away, so that the pressure in the cavity 15 drops below the atmospheric pressure, thereby forming a certain vacuum degree. The air in the negative pressure air intake port 13 and the air intake channel 131 is sucked into the cavity 15, and finally the air enters the air outlet channel 141 and is silenced by the silencer 14.

[0029] Furthermore, a fixing block 22 is installed between the end of the threaded column 23 and the mounting base 21 , and the mounting base 21 is connected to the mounting hole 111 through a plurality of bolts.

[0030] Furthermore, an annular groove 241 is formed at the end of the adjusting sleeve 24 , and a limiting ring 251 is formed inside the connecting head 25 , and the limiting ring 251 is in contact with the inner wall of the annular groove 241 .

[0031] By means of the limiting ring 251 and the annular groove 241 , the connector 25 can rotate relative to the adjusting sleeve 24 without being separated from the adjusting sleeve 24 .

[0032] During use, the mounting base 21 can be arbitrarily fixed on the top, bottom and both sides of the housing 11 by using the mounting holes 111 opened on the top, bottom and both sides of the housing 11, and after the mounting base 21 is installed on the outside of the housing 11, the adjusting sleeve 24 can be rotated so that the adjusting sleeve 24 moves relative to the threaded column 23, thereby adjusting the distance between the connector 25 and the housing 11, and the connector 25 can be rotated relative to the adjusting sleeve 24, which makes it more convenient to connect the connector 25 with external equipment;

[0033] At this time, the external nozzle is connected to the air inlet 12, and the external nozzle is used to spray compressed air at high speed toward the air inlet 12. After the compressed air is sprayed out from the nozzle 121, a jet is formed in the cavity 15, generating a suction flow. Under the suction effect, the air around the nozzle outlet is continuously sucked away, so that the pressure in the cavity 15 drops below the atmospheric pressure, thereby forming a certain vacuum degree. The air in the negative pressure suction port 13 and the suction channel 131 is sucked into the cavity 15. After the negative pressure suction port 13 is connected to the vacuum suction cup and other equipment, it can play its negative pressure suction role. Finally, the air enters the air outlet channel 141 and is silenced by the silencer 14.

[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
