The economizer 1 includes a main body 10, an elastic member 20, a valve 30, a valve chute 40, and a vacuum generator 50.
In an embodiment of the present invention, the main body 10 includes a main body air inlet 11, a main body air outlet 12, a first cavity 13 and a second cavity 14. The main body inlet end 11 is connected to the vacuum pump outlet end 110 to receive the gas exhausted from the vacuum pump outlet end 110. The main body gas outlet end 12 is connected to the exhaust pipe 200 to exhaust gas to the exhaust pipe 200, and then the exhaust pipe 200 discharges the gas to the outside. The first cavity 13 communicates with the body inlet end 11. The second cavity 14 is communicated with the main body air outlet end 12 and the first cavity 13.
In an embodiment of the present invention, the valve 30 is located in the second cavity 14, and can move up and down in the second cavity 14 to the communication position blocking or keeping away from the first cavity 13 and the second cavity 14, so that the communication relationship between the first cavity 13 and the second cavity 14 is closed or opened.
In an embodiment of the present invention, the valve chute 40 is disposed in the second chamber 14. The valve gate chute 40 includes a chute portion 41 and two air ports 42. The valve 30 moves up and down within the chute portion 41 to block or move away from the communication between the first and second chambers 13 and 14. The vent 42 is for allowing gas to pass therethrough to flow toward the exhaust pipe 200 to be discharged to the outside; however, the number of the vents 42 is not limited to two, and may be changed to one according to design requirements.
In one embodiment of the present invention, the vacuum generator 50 includes a vacuum generator inlet 51, a vacuum generator outlet 52 and a flow adjusting member 53. The vacuum generator inlet 51 is connected to the first chamber 13, and the vacuum generator inlet 51 is used for allowing the gas in the first chamber 13 to flow in. The vacuum generator outlet 52 is connected to the second chamber 14, and the vacuum generator outlet 52 is used for allowing gas to flow into the second chamber 14. The gas flow adjusting member 53 is connected to the first chamber 13 and the second chamber 14, the gas flow adjusting member 53 is used for providing an active gas flow towards the vacuum generator outlet 52, the active gas flow pulls a gas flow in the vacuum generator inlet 51 towards the vacuum generator outlet 52, and pulls and extracts a gas flowing from the vacuum pump outlet 110 into the first chamber 13, so that the gas pressure in the vacuum pump 100 maintains a negative pressure. The active flow of the flow adjuster 53 pushes the gas to the vacuum generator outlet 52, and flows into the second chamber 14, through the two vents 42, and to the outside through the main body outlet 12.
In an embodiment of the present invention, the elastic member 20 is, for example, a spring, and connects the slide groove portion 41 and the valve 30. The elastic member 20 provides an elastic force to the valve 30, so that the valve 30 moves downward to block the communication between the first chamber 13 and the second chamber 14, so as to close the communication between the first chamber 13 and the second chamber 14.
As shown in fig. 1 and 2, in an embodiment of the present invention, when a user needs to use the energy saving device 1 on the vacuum pump 100 to save energy of the vacuum pump 100, first, the user needs to combine the vacuum pump outlet 110 of the vacuum pump 100 with the main body inlet 11, and selectively combine the exhaust pipe 200 with the main body outlet 12.
Then, when the vacuum pump 100 is in standby, an air-extracting motor (not shown) in the vacuum pump 100 still waits to rotate at a low speed to exhaust a small amount of residual gas; at this time, the elastic force applied to the valve 30 by the elastic member 20 may move the valve 30 downward to block the communication between the first cavity 13 and the second cavity 14, so as to close the communication between the first cavity 13 and the second cavity 14. The gas flow adjusting member 53 provides an active gas flow toward the vacuum generator outlet 52, and the active gas flow pulls a gas flow in the vacuum generator inlet 51 toward the vacuum generator outlet 52 to pull and extract a gas flowing from the vacuum generator outlet 110 into the first chamber 13; after the gas flow adjusting member 53 pulls and extracts the gas flowing from the vacuum pump outlet 110 into the first chamber 13, the active gas flow of the gas flow adjusting member 53 pushes the gas along the gas flow guiding direction B to the vacuum generator outlet 52 and flows into the second chamber 14, and then flows to the outside through the vent 42 and the main body outlet 12. Therefore, the valve 30 and the vacuum generator 50 can block the external atmospheric pressure from directly affecting the vacuum pump 100, so that the gas pressure in the vacuum pump 100 is not pulled by the external atmosphere, the gas pressure in the vacuum pump 100 can maintain a stable negative pressure, and the pumping motor in the vacuum pump 100 does not need to consume more power to maintain the negative pressure, thereby achieving the effects of energy saving and power saving.
In addition, as shown in fig. 3, when the vacuum pump 100 operates, the vacuum pump 100 may draw gas toward a specific object (not shown) and input a large amount of the drawn exhaust gas into the first chamber 13, and the large amount of the exhaust gas may push the valve 30 to move upward, so that the communication relationship between the first chamber 13 and the second chamber 14 is opened; thereby, the exhaust gas can directly flow from the first chamber 13 to the second chamber 14 along the outlet direction C of the vacuum pump, collide with the valve 30, turn along the exhaust direction D, pass through the two vents 42 along the exhaust direction E, and finally flow to the outside along the exhaust direction F and through the outlet end 12 of the main body. After the vacuum pump 100 stops inputting the extracted exhaust gas into the first chamber 13, the elastic member 20 provides an elastic force to the valve 30, so that the valve 30 moves to block the communication between the first chamber 13 and the second chamber 14, thereby cutting off the communication between the first chamber 13 and the second chamber 14.
Through the utility model discloses a structural design of vacuum pump can the outside atmospheric pressure of separation, can let the gas pressure in the vacuum pump can not receive outside atmosphere and pull, and gas pressure in the vacuum pump can maintain stable negative pressure, and the air exhaust motor in the vacuum pump need not consume more electric power and maintains the negative pressure, so can reach the efficiency of energy saving.
