DETAILED DESCRIPTION

[0021] The utility model will be further described below in conjunction with the accompanying drawings.

[0022] like Figures 1 to 3 As shown, the automatic oiler comprises a base 1, and a grease tank 12 for containing grease is connected above the base 1;

[0023] The base 1 is provided with a control panel 6 and a power module connected and controlled by the control panel 6;

[0024] The power module includes a base 11, which is provided with an oil outlet 15 and an oil inlet 13 connected to a grease tank 12, and the oil inlet 13 and the oil outlet 15 are both provided with a one-way valve (not shown in the figure), the oil outlet 15 is connected with an extension pipe 4 extending out of the machine base 1, and the base 11 is provided with an oil cavity 14 connecting the oil inlet 13 and the oil outlet 15, and the base 11 is also provided with a reciprocating power mechanism for extracting oil from the oil inlet 13 and sending it out from the oil outlet 15;

[0025] A control terminal 5 connected to a control panel 6 is disposed on the surface of the base 1 .

[0026] The setting can be performed through the control terminal 5, and the power module can be controlled through the control panel 6. The reciprocating power mechanism is used to extract oil from the oil inlet 13 and discharge it from the oil outlet 15, so as to achieve stable and accurate control of the oil output, thereby achieving the effect of controlling the oil injection amount.

[0027] In order to achieve stable extraction and pushing of oil, further, the reciprocating power mechanism includes an electric push rod 19 connected to the control panel 6, the power output end of the electric push rod 19 is connected to the piston rod 10, one end of the piston rod 10 is movably connected to the front end sleeve 7, and a first cavity 17 for fixing the front end sleeve 7 is provided in the base 11, and the end of the first cavity 17 is connected to the oil chamber 14. The electric push rod 19 provides driving force to control the movement of the piston rod 10, thereby forming a negative pressure in the front end sleeve 7. The one-way valve at the oil outlet 15 can prevent the oil in the extension tube 4 from being drawn back, and the oil can only be drawn into the oil chamber 14 through the oil inlet 13. As the piston rod 10 returns to its original position, the setting of the one-way valve at the oil inlet 13 can prevent the reverse pressure of the piston rod 10 from pushing the oil to the grease tank 12, and the oil can only be discharged from the oil outlet 15. As the piston rod 10 reciprocates, a quantitative amount of oil is pushed.

[0028] In order to reduce the space occupied in the machine base 1 , further, the electric push rod 19 is arranged in parallel with the piston rod 10 , and the power output end of the electric push rod 19 is connected to the middle part of the piston rod 10 through a connecting rod 18 .

[0029] In order to enhance the operational stability of the piston rod 10, further, one end of the piston rod 10 away from the oil chamber 14 is movably connected with a rear end sleeve 8, a second cavity 9 for fixing the rear end sleeve 8 is provided in the base 11, and the end of the second cavity 9 is opened on the side of the base 11, the second cavity 9 is connected with the outside, and the piston rod 10 can also avoid forming a pressure space in the second cavity 9, thereby facilitating the movement of the piston rod 10.

[0030] During actual use, the oil outlet 15 may sometimes be clogged. If it is not discovered in time, it will affect the normal oil filling. Furthermore, a pressure sensor 16 connected to the control board 6 is provided in the oil chamber 14. Once the oil outlet 15 is clogged, it will affect the outward push of oil. The pressure sensor 16 will have unstable pressure changes, which will be fed back to the control terminal 5 so that maintenance can be carried out in time.

[0031] Furthermore, the top of the grease tank 12 is open, and a dust cover 3 is provided on the outside. The bottom of the dust cover 3 is connected to the machine base 1 through a fixing nut 2. The top opening of the grease tank 12 can facilitate the downward flow of oil, and the dust cover 3 can provide a good dustproof effect.

[0032] When the utility model is in use: the reciprocating frequency and displacement of the piston rod 10 can be pre-set through the control terminal 5, so as to perform timed and quantitative oil injection. The control terminal 5 can be operated through a network, which is convenient for unified management. During specific operation, the electric push rod 19 drives the piston rod 10 to move toward the second cavity 9, so that negative pressure is formed in the first cavity 17, and oil is drawn from the oil inlet 13 into the oil cavity 14. As the piston rod 10 moves from the second cavity 9 to the first cavity 17 driven by the electric push rod 19, the oil in the oil cavity 14 is pushed to be discharged outward from the oil outlet 15, thereby forming an oil injection action.
