However, the air source module of the existing lubricator is basically configured to be integrated at one end of the oil filling tank, so that the lubricator is configured as a disposable product. After the grease in the lubricator is used up, it is directly discarded, making the lubricator non-reusable. In this regard, it is necessary to propose an improved technical solution to solve the above problems. Utility Model Content

[0009] Preferably, a sealing ring is provided on the gas source body along the periphery of the boss, and the gas source body and the oil filling tank are sealed and matched via the sealing ring.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] After the grease in the lubricator is used up, the user can disassemble the air source body and the piston and then add new grease into the oil filling tank. After adding the new grease, first install the piston into the oil filling tank, and then connect the air source module. The air source module generates a push to make the piston move forward, squeeze out the grease to lubricate the machine, so as to achieve the purpose of adding new grease.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-6 In the embodiment of the present utility model, please refer to Figures 1-2 In the embodiment of the utility model, an oil injector which is easy to disassemble and fully use is proposed, including an oil injection tank 10, the oil injection tank 10 is provided with an oil injection port 11, a piston 20 is slidably assembled inside the oil injection tank 10, and also includes an air source module docked with the oil injection tank 10, the air source module includes an air source body 30 detachably connected to the oil injection tank 10, a pump body 31 installed inside the air source body 30, a pressure injection port 32 arranged on the air source body 30 and docked inside the oil injection tank 10, an air suction port (not shown) arranged on the air source body 30 and located outside, and a circuit module 34 arranged inside the air source body 30, the pump body 31 is electrically connected to the circuit module 34, and the pump body 31 is respectively connected to the pressure injection port 32 and the air suction port, so as to suck the external gas into the oil injection tank 10 in a one-way manner;

[0033] During the production process, grease is injected into the oil filling tank 10. When in use, the oiler is installed at the position of the equipment for oiling, and then the oiler is started. The oiler controls the amount of oil injected into the pump body 31 through its internal circuit module 34. The circuit module 34 is generally configured to have a timer, which can drive the pump body 31 within a certain time period according to the timer, thereby periodically injecting gas into the oiler. After the gas is injected, air pressure is generated in the oil filling tank 10, thereby pushing the piston 20 to squeeze the grease out from the position of the oil filling port 11, thereby supplying it to the corresponding equipment. The operation will be completed automatically throughout the process without manual operation, so that the equipment does not need to be oiled during long-term use; the lubrication of the equipment can be better maintained.

[0034] The utility model is based on the above technical solution, and improves the structure of the oiler. Specifically, the oil filling tank 10 is provided with a connecting port 12, and the piston 20 can be detachably assembled in the oil filling tank 10 along the connecting port 12. The air source main body 30 is detachably connected to the connecting port 12, so that the oil filling tank 10 and the air source module are connected to form a accommodating chamber with an oil filling port 11, and the accommodating chamber is divided into an oil storage chamber 13 with the oil filling port 11 and a pressure chamber 14 corresponding to the air source module by the piston 20, and the pressure injection port 32 acts on the pressure chamber 14.

[0035] Through this arrangement, after the grease in the lubricator is used up, the user can disassemble the gas source body 30 and the piston 20 and then add new grease into the oil filling tank 10. After adding the new grease, the piston 20 is first installed into the oil filling tank 10, and then the gas source module is connected, so as to achieve the purpose of adding new grease. In this way, the lubricator can be circulated to add grease, thereby increasing the service life of the lubricator.

[0036] The piston 20 and the gas source body 30 are disassembled by the connection port 12, so that the oil filling tank 10, the piston 20 and the gas source module can form three independent parts. During the maintenance of the oiler itself, the oiler can be used normally by repairing and replacing only a certain part, without directly replacing the entire oiler, so that its maintenance cost is greatly reduced;

[0037] Furthermore, by configuring the oil filling tank 10 and the gas source module as two independent entities, in actual production applications, oil filling tanks 10 with different storage capacities can be configured based on different usage requirements, thereby improving the flexibility of the size design of the oil filling tank 10.

[0038] See also Figure 1-5 In the embodiment of the utility model, the oil filling port 11 is arranged at the upper end of the oil filling tank 10, and the connecting port 12 is arranged at the lower end of the oil filling tank 10. The diameter of the connecting port 12 is consistent with the inner diameter of the oil filling tank 10. Through this arrangement, the structural design is simple, thereby giving the oiler a complete appearance line curvature. A boss structure 35 is protruding from the gas source body 30, and an external thread 36 is provided on the outer wall of the boss structure 35. An internal thread 15 matching the external thread 36 is provided at the inner wall of the oil filling tank 10 corresponding to the connecting port 12. The gas source body 30 and the oil filling tank 10 are detachably connected through the threaded connection of the external thread 36 and the internal thread 15. The structural design is simple and can make the radial dimensions of the outer side of the gas source body 30 and the outer side of the oil filling tank 10 consistent, thereby ensuring the integrity of their appearance; a sealing ring 37 is provided along the periphery of the boss on the gas source body 30, and the gas source body 30 and the oil filling tank 10 are sealed and matched by the sealing ring 37, so that the oil filling tank 10 and the gas source body 30 maintain a sealed connection to prevent the gas injected into the air pressure chamber 14 from overflowing.

[0039] See also Figure 5 In the embodiment of the utility model, the injection port 32 is a sleeve-shaped structure extending into the air pressure chamber 14, and a one-way valve 38 is arranged inside the injection port 32. The one-way valve 38 is connected to the pump body 31, thereby effectively preventing gas reflux caused by excessive air pressure.

[0040] See also Figure 2-6In the embodiment of the utility model, the circuit module 34 includes a circuit main board 341 and a battery 342 electrically connected to the circuit main board 341. The pump body 31 is electrically connected to the circuit main board 341, so that the oiler can be connected to the device for a long time without an external power supply line; and the circuit main board 341 is also electrically connected to a distance sensor 343, and the distance sensor 343 is used to detect the active stroke of the piston 20. The distance sensor 343 can identify the active stroke of the piston 20 to determine the current grease content inside the oiler. When the grease is insufficient, control alarms and other operations can be performed to prompt the user to add grease; its alarm and other operations are set based on demand. , it can be a conventional alarm system such as a light alarm and a voice alarm. In addition, the distance sensor 343 can adopt a capacitive liquid level sensor, an ultrasonic liquid level sensor, a photoelectric liquid level sensor, etc.; the capacitive liquid level sensor can use the different dielectric constants of liquid and air. When the liquid level changes, the capacitance value changes, thereby detecting the amount of oil; the ultrasonic liquid level sensor transmits ultrasonic waves to the surface of the piston 20 and receives the reflected ultrasonic waves, and calculates the liquid level height according to the propagation time; the photoelectric liquid level sensor uses the principle of refraction and reflection of light. When the stroke of the piston 20 changes, the optical path changes, thereby detecting the amount of grease.

[0041] See also Figure 1 In the embodiment of the utility model, the oil filling port 11 is formed with a connecting sleeve 16 extending from the oil filling tank 10, and the oiler is fixedly installed by the connecting sleeve 16. The connecting sleeve 16 can be connected to some oil supply ports on the equipment by threaded connection, so that it can supply lubricating oil to this part of the equipment for a long time.

[0042] See also Figure 2-3 In the embodiment of the utility model, the piston 20 is a disc-shaped structure, the side wall of the piston 20 is sealed and slidably connected to the inner wall of the oil filling tank 10, and a protrusion 21 that can extend into the connecting sleeve 16 is provided on the piston 20, so that the grease in the oil filling tank 10 can be injected into the device as much as possible;

[0043] See also Figure 2-3In the embodiment of the utility model, the circuit main board 341 is also connected to a time adjustment knob 33, which is exposed outside the gas source body 30 to facilitate intuitive and convenient operation by the operator; when the operator rotates and adjusts the time adjustment knob 33, a series of electronic signal transmission and processing processes can be triggered. Specifically, through this operation, an oil injection amount control signal corresponding to the adjustment action can be generated, and the signal can be accurately transmitted to the circuit main board 341. After receiving this control signal, the circuit main board 341 will immediately accurately control the relevant components and mechanisms inside the oiler. Under this precise control, grease can be squeezed out of the oiler in a controllable amount in an orderly manner. The extruded grease will be accurately applied to the corresponding equipment along the preset channels and paths. Because different equipment has significant differences in the amount of grease required for lubrication, maintenance, etc. during operation. Some equipment may require more grease to ensure adequate lubrication due to high work intensity and high speed; while some equipment only needs a small amount of grease to maintain normal operation due to compact structure and small workload. By setting the time adjustment knob to control the oil output of the oiler, it is possible to flexibly adapt to the diverse and personalized needs of these different equipment for the amount of grease, providing a solid guarantee for the stable operation and efficient work of the equipment; for example, on an automated production line, large-scale mechanical equipment running at high speed may need to adjust the time adjustment knob 33 to a longer oiling time to ensure that a larger amount of grease can be injected each time to ensure adequate lubrication and reduce wear; and for some small auxiliary equipment, it is only necessary to adjust the time adjustment knob 33 to a shorter oiling time and inject a small amount of grease to meet its lubrication needs.

[0044] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
