The oil outlet pipe connector 3 is pre-connected to the conduit of the lubricating oil spray gun and the output is controlled by the spray gun. In the pressurization mechanism, the output of the air pump 7 is monitored by the air pressure monitoring pipeline 8.

[0033] In a further preferred embodiment, the bottom of the air pump 7 is fixed with a socket 6, the socket 6 is inserted into the outer wall of the frame 1 and is threadedly connected to the frame 1 with a bolt, and the air outlet of the air pump 7 is detachably connected to the air pressure monitoring pipeline 8 with a first conduit 9.

[0034] The air pump 7 is installed on the frame 1 via the socket 6, and the socket 6 is fixed to the frame 1 with bolts, which can be disassembled and installed to assist in the inspection and maintenance of the air pump 7. The air pump 7 and the air pressure monitoring pipeline 8 are mainly connected through the first conduit 9 and work together.

[0035] In a further preferred embodiment, the oil drum 2 is tilted and fixed to the outer wall of the frame 1, one end of the oil inlet pipe head 4 is threaded with a cap 5, and a second conduit 10 is detachably connected between the oil inlet pipe head 4 and the air pressure monitoring pipeline 8.

[0036] The tilted installation of the oil drum 2 allows the lubricating oil stored inside to move better toward the oil outlet connector 3 due to gravity. The oil inlet connector 4 is normally sealed by the cap 5, which is turned open when lubricating oil needs to be stored.

[0037] More preferably, one end of the air intake chamber 11 has an air inlet, and the other end away from the air inlet is provided with a pipe joint. A third conduit 12 is detachably connected between the pipe joint of the air intake chamber 11 and the air inlet end of the air pump 7.

[0038] The air intake chamber 11 ensures the entry of gas through the air inlet at one end, and the pipe connector at the other end is connected to the third conduit 12 to deliver gas to the air pump 7.

[0039] A further preferred embodiment has a threaded connector 18 fixed at the bottom of the air intake chamber 11, with one end of the threaded connector 18 penetrating the frame 1 and secured with a nut;

[0040] The air intake chamber 11 is fixed to the frame 1 by the engagement of the threaded connector 18 and the nut. The air intake chamber 11 can be separated from the base frame by rotating and removing the nut.

[0041] More preferably, a handle 16 and a control box 17 are fixed to the outer wall of the frame 1 respectively. The outer wall of the control box 17 is provided with an external terminal, which is used to connect the control air pump 7 and the external power supply respectively.

[0042] The frame 1 is pushed by the staff with the help of the handle 16. The air pump 7 is operated by the control box 17. The control box 17 has a built-in air pump 7 controller and is connected to the air pump 7 and the power supply through the external terminal to ensure the operation of the air pump 7.

[0043] More preferably, a magnetic ring 15 is fixed to the top of the air intake chamber 11 corresponding to the chamber cover 13, and the magnetic ring 15 is magnetically connected to the bottom of the chamber cover 13;

[0044] The cover 13 is made of iron and can be magnetically held in place by the magnetic ring 15. Personnel can also directly pull open the cover 13 to operate inside the air intake chamber 11.

[0045] One specific application of this embodiment is as follows: Lubricating oil is first put into oil tank 2 through oil inlet head 4 for pre-storage. Oil tank 2 is pre-connected to the spray gun's conduit by oil outlet head 3. Personnel can push frame 1 through handle 16 and use the wheels at the bottom of frame 1 to transfer the corresponding mechanical equipment that needs lubrication. After being transferred to the work site, the lubricating oil in oil tank 2 is released through the spray gun connected by oil outlet head 3. At the same time, air pump 7 draws air from air inlet chamber 11 through third conduit 12, and then enters air pressure monitoring pipeline 8 through first conduit 9 for monitoring. After that, the second conduit 10, together with oil inlet head 4, enters oil tank 2 to assist in pushing and make the lubricating oil output more smoothly from oil outlet head 3.

[0046] When the air pump 7 draws air through the air intake chamber 11, external air enters the air intake chamber 11 through the air inlet. This air entering the air intake chamber 11 is filtered by the air filter element 14 to reduce moisture and impurities before entering the air pump 7 through the third conduit 12 connected by the pipe connector, making the air entering the air pump 7 cleaner. When the air intake chamber 11 needs cleaning and maintenance, the nut of the threaded connector 18 and the third conduit 12 connected by the pipe connector can be disconnected, and the air intake chamber 11 can be removed. The chamber cover 13 can be pulled out directly to clean the inside of the air intake chamber 11 and the air filter element 14.
