[0029] Embodiment 1

[0030] Referring to the attached Figure 1-2 , an air compressor lubrication device of this embodiment includes an oil tank 100, an oil pump 200 and an oil pipe 300. The oil tank 100 is connected to the compressor body through the oil pipe 300 and forms a loop. The oil pump 200 is located on the oil pipe 300 and is used to extract the lubricating oil in the oil tank 100 and transport it into the compressor body. The oil tank 100 includes a fixing frame 110, a bottom tank 120, a cooling shell 130 and a cooling fan 140. The bottom tank 120, the cooling shell 130 and the cooling fan 140 are all installed on the fixing frame 110, and the cooling shell 130 is communicated with the bottom tank 120.

[0031] The cooling shell 130 of this embodiment includes a plurality of square shells connected end to end and internally communicated. The adjacent square shells form an angle of 30°. The cooling shell 130 is located above the bottom tank 120, and the cooling fan 140 is located on one side of the cooling shell 130.

[0032] A connecting plate is also provided between the adjacent square shells of this embodiment for connection, and protective plates 150 are provided at both ends of the square shell.

[0033] In the square shell at the uppermost position among the multiple square shells of this embodiment, a filter screen is provided, and the square shell provided with the filter screen is connected to the oil pipe 300 through a flange.

[0034] On the fixing frame 110 of this embodiment, connecting ears are provided, and waist-shaped holes are provided on the connecting ears.

[0035] Working principle: lubrication is carried out through circulating lubricating oil, in which the lubricating oil is conveyed by the oil pump 200. The lubricating oil that has been lubricated and absorbed heat first enters the cooling shell 130 for cooling, and finally flows into the bottom tank 120 for circulation. Since the cooling shell 130 is of a flat structure, the contact area between the lubricating oil and the cooling shell 130 is increased. The cooling shell 130 absorbs heat and is dissipated by the cooling fan 140. Therefore, cooling can be continuously and stably carried out. In addition, the cooling shell 130 is designed into a Z-shaped structure, which can increase the contact area between the lubricating oil and the cooling shell and achieve better cooling.

[0036] The above-described embodiments only represent certain implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present utility model; it should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model; therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
