[0023] The following further describes the utility model with reference to the drawings.

[0024] As Figures 1 to 4As shown in the figure, the quantitative control oil injection controller includes a base 1. Above the base 1, there is a grease tank 5 for containing grease. Inside the base 1, there is a control board 7 and a power module controlled by the control board 7. On the surface of the base 1, there is a control terminal 3 connected to the control board 7. It is characterized in that the power module includes a base 6. Above the base 6, it is connected to the grease tank 5 through a connecting piece 17. On the upper surface of the base 6, there is an oil inlet 12 corresponding to the connecting piece 17. On the lower surface of the base 6, there is an oil outlet 15 corresponding to the oil inlet 12. One-way valves are provided on both the oil inlet 12 and the oil outlet 15.

[0025] Connected to the oil outlet 15 is an extension pipe 4 that extends vertically downward from the bottom of the base 1.

[0026] Inside the base 6, there is an oil cavity 11 vertically provided that communicates with the oil inlet 12 and the oil outlet 15.

[0027] On the base 6, there is still a reciprocating power mechanism for pumping and delivering grease that communicates with the oil cavity 11.

[0028] Through the control terminal 3, settings can be made. Through the control board 7, the power module is controlled. Using the reciprocating power mechanism, it extracts from the oil inlet 12 and then discharges from the oil outlet 15 to achieve stable and precise control of the oil output, thereby achieving the effect of controlling the oil injection volume.

[0029] In order to achieve stable extraction and pushing of oil, further, the reciprocating power mechanism includes an electric push rod 10 connected to the control board 7. The power output end of the electric push rod 10 is connected to a piston rod 9. Inside the base 6, there is a connecting cavity. At one end of the connecting cavity away from the piston rod 9, there is a pumping hole 13 communicating with the oil cavity 11. Inside the connecting cavity, a copper sleeve 14 is fixedly provided. The copper sleeve 14 sleeved on the end of the piston rod 9. At one end of the piston rod 9 located inside the copper sleeve 14, there is a rubber sealing ring 16.

[0030] When the electric push rod 10 drives the piston rod 9 to move towards the end away from the oil cavity 11, a negative pressure is formed inside the copper sleeve 14, thereby opening the one-way valve at the oil inlet 12 to extract grease through the oil cavity 11 and enter the copper sleeve 14 through the pumping hole 13. As the electric push rod 10 retracts and drives the piston rod 9 to move towards the oil cavity 11, the grease inside the copper sleeve 14 is compressed and enters the oil outlet 15 through the pumping hole 13, thereby forming a quantitative oil output effect.

[0031] In order to reduce the space occupation inside the base 1, further, the piston rod 9 is parallel to the electric push rod 10. The power output end of the electric push rod 10 is connected to the end of the piston rod 9 away from the copper sleeve 14 through a connecting piece 8.

[0032] For the convenience of operating and controlling the quantitative control oil injection controller, a quantitative design is carried out according to the usage requirements. Further, the control terminal 3 includes an acrylic observation window 3.1, a liquid crystal screen 3.2 is installed at the rear side of the observation window 3.1, and a membrane key 3.3 is arranged at the lower side of the observation window 3.1. The liquid crystal screen 3.2 and the membrane key 3.3 are connected to the control board 7.

[0033] Further, the top opening 5.1 of the grease tank 5 is provided, and a dust-proof cover 2 which is hermetically connected to the machine base 1 is sleeved outside. Equipping the dust-proof cover 2 can provide a good dust-proof effect.

[0034] When the present utility model is in use: the reciprocating frequency and displacement of the piston rod 9 can be preset through the control terminal 3, so as to extract the grease in the grease tank 5 regularly and quantitatively and convey it outwards. The control terminal 3 can be operated by networking, which is convenient for unified management; during specific work, the electric push rod 10 drives the piston rod 9 away from the oil cavity 11, so that a negative pressure is formed in the copper sleeve 14, thereby opening the one-way valve at the oil inlet 12 to extract the grease through the oil cavity 11 and enter the copper sleeve 14 through the pumping hole 13. As the electric push rod 10 retracts to drive the piston rod 9 to move towards the oil cavity 11, the grease in the compression channel enters the oil cavity 11, so that the one-way valve at the oil outlet 15 is opened to convey the grease outwards, thus forming an oil injection action.
