[0041] In one embodiment, please refer to Figures 4 to 6 The intelligent oil injector also includes a coupling 120, which is used to drive the output shaft of the drive module 110 and the screw 230. The coupling 120 is equipped with a code disk 122, which has a number of code teeth 1221 distributed circumferentially. A photoelectric sensor 160 is used to sense the rotational stroke of the code teeth 1221 and convert the rotational stroke into an electrical signal of the oil output.

[0047] The oil injection amount of the oil injector can be controlled through the main control board 170. Since the main control board 170 is provided with the communication module, the main control board 170 can also communicate the electric signal of the oil output to an external network system through the communication module, and control the rotary motion parameters of the driving module 110 according to the instruction of the external network system, so as to realize flexible adjustment of the oil injection amount. Specifically, the communication module can be selected as a Bluetooth module or a wifi module.

[0048] In the embodiment, the code teeth 1221 are circumferentially distributed on the code disc 122 at 8 to 16, further, the code teeth 1221 are circumferentially distributed on the code disc 122 at 8, 10, 12, 14 or 16. Of course, in other embodiments, according to the accuracy requirement of the oil injection amount of the oil injector, the code teeth 1221 can also be circumferentially distributed on the code disc 122 at 20 or more other numbers.

[0049] In an embodiment, referring to Figure 4 and Figure 6The oil cup 200 comprises a sealing ring 240, a circumferential outer wall of the pressing oil disc 220 is provided with a sealing groove 221, the sealing ring 240 is arranged in the sealing groove 221 and elastically abuts between a groove wall of the sealing groove 221 and a wall of the oil cavity 211 of the cup body 210.

Through the threadedly connected mode, the oil cup 200 is convenient to disassemble and replace. Of course, in other embodiments, other buckle structures or screw connection and other installation modes can be adopted to realize the disassembly and replacement of the oil cup 200.

[0052] In an embodiment, referring to Figure 7 and Figure 8 、 Figure 10 and Figure 11 An axial end surface of the cup body 210 is further provided with a first positioning tooth 215, a second positioning tooth 1331 is formed on an outer wall of the host shell 130, and the first positioning tooth 215 is positioned and matched with the second positioning tooth 1331 to limit the rotation of the cup body 210 relative to the host shell 130, so that the rotation movement output by the driving module 110 can be stably transmitted to the screw rod 230 and the pressing oil disc 220, and the working of the oil injector is stable and reliable.

[0053] In an embodiment, referring to Figure 1 A ventilation hole 142 is formed on a wall surface of the protective cover 140 and is used for communicating the inner and outer spaces of the protective cover 140. Through the arrangement of the ventilation hole 142, the linear movement of the pressing oil disc 220 in the oil cavity 211 is more stable and reliable, and the large pressure change of the space close to the host 100 side of the pressing oil disc 220 caused by the linear movement of the pressing oil disc 220 is avoided, so that the smooth movement of the pressing oil disc 220 is not affected.

[0054] In an embodiment, referring to Figure 7 The host 100 further comprises a battery 150, the host shell 130 comprises a shell body 131, a battery cover 132 and a mounting seat 133, the shell body 131 is provided with a receiving groove, a receiving opening axially provided on the shell body 131 and communicated with the receiving groove, a battery groove 1311 and a battery 150 opening radially provided on the outer wall of the shell body 131, the drive module 110 is installed in the receiving groove through the receiving opening, the mounting seat 133 is axially assembled at the receiving opening, and the battery cover 132 is covered on the battery 150 opening.

[0055] By such an arrangement, the battery 150 can be replaced after the battery power is consumed. Specifically, the battery 150 can be a battery combination composed of a plurality of battery 150 blocks, thereby improving the endurance of the oiler.

[0056] In an embodiment, referring to 1 and Figure 7 The outer wall of the protective cover 140 is provided in a prismatic shape, which facilitates the rotation of the protective cover 140 by the operator, thereby achieving the disassembly and replacement of the oil cup 200 or the battery 150.

[0057] In an embodiment, referring to Figure 4 and Figure 6 The intelligent oiler further comprises an adapter 300, the adapter 300 is provided with an oil outlet channel 310 communicated with the oil outlet 213, the adapter 300 is detachably connected to the oil cup 200 and is used for external installation. By providing the adapter 300, the corresponding adapter 300 can be matched and installed according to different installation scenes of the mechanical equipment, thereby increasing the application adaptability of the oiler.

[0058] Further, the adapter 300 is a flange adapter, the cup body 210 is a structural member made of plastic material, the flange adapter is a structural member made of metal, the adapter 300 is threadedly connected to the flange adapter and is used for supporting the oil cup 200. It can be understood that the plastic cup body 210 has poor reliability and low structural strength and is easy to be damaged. By increasing the supporting effect of the flange adapter, the oiler can be better supported, thereby increasing the working stability and reliability thereof.

[0059] In an embodiment, the rotation movement output by the drive module 110 is not greater than 100 revolutions per minute. The screw rod 230 is driven to rotate at a relatively small speed, thereby controlling the oiling measurement.

[0061] In an embodiment, the driving module 110 comprises a driving motor and a speed reducer, and the driving motor and the speed reducer are integrated as an integrated module; by so arranging, the integrated assembly and maintenance of the driving module 110 are facilitated.

[0062] It can be understood that the rotating speed of the driving motor can be selected to be greater than 10000 rpm, and the rotating speed of the rotating motion is reduced through the speed reducer, so that the rotating speed output by the driving module 110 is not greater than 100 rpm, so as to reach the injection standard of the oil into the mechanical equipment. Of course, according to the different oil injection requirements of the mechanical equipment, the output rotating speed of the driving module 110 can be changed by adjusting the speed reduction ratio of the speed reducer, for example, the output rotating speed of the driving module 110 can be specifically 5 rpm, 10 rpm, 20 rpm, 35 rpm, 50 rpm or 100 rpm, etc. Specifically, the speed reducer can be selected to be a gear box. Of course, in other embodiments, the working rotating speed of the driving motor can also be adjusted synchronously, for example, a driving motor with a rotating speed of 8000 rpm is used.

[0063] In yet another embodiment, the driving module 110 is a direct drive motor, and the difference from the last embodiment is that, in the present embodiment, the driving module 110 does not need to be provided with a speed reducer, and a low rotating speed direct drive motor is directly used to make the driving module 110 output a low rotating speed.

[0064] The above only discloses the preferred embodiments of the utility model, and of course cannot limit the scope of the utility model, so equivalent changes made according to the utility model claims still belong to the scope covered by the utility model.
