[0029] Furthermore, the oil collection assembly also includes a second collection tank 14 , and the top side end of the first collection and detection tank 5 is connected to the top side end of the second collection tank 14 through a flow pipe 15 .

[0030] Furthermore, the flow pipe 15 is installed on the L plate 12 in a limited manner.

[0031] Further, the oil sensor 10 is installed at the bottom side of the first collecting and detecting tank 5, a sensing rod 16 is provided on the oil sensor 10, an oil inlet hole 17 is provided on the sensing rod 16, and the sensing rod 16 extends into the first collecting and detecting tank 5. Of course, the oil sensor 10 is not limited to the horizontal installation shown in the figure, but can also be installed vertically.

[0038] Taking the multifunctional screw air compressor case in Example 1 as an example, the filter plate 6 first filters the oil, and the oil enters the first collection detection tank 5 through the flow channel 7. However, when the oil flows to the top of the floating plate 8, the oil will first flow to the bottom of the floating plate 8 through the hole 11 on the floating plate 8. When the oil collection volume reaches the top of the low point limiter 91, the oil will lift the floating plate 8 until the floating plate 8 contacts the high point limiter 92.

[0039] Example 2

[0040] This embodiment provides a multifunctional screw air compressor case. The difference between this embodiment and embodiment 1 is that: the top surface of the bottom plate 2 is optimized so that the fluid dripping on the bottom plate 2 can flow to the flow channel 7 instead of flowing around the outside of the bottom plate 2.

[0041] The structure of the air compressor mainly includes an air storage barrel 100, an oil and gas barrel 110 installed through a mounting frame, a motor 105, a main unit 106, etc. Usually, the bottom is the air storage barrel 100 (or called an air tank), a mounting frame is set up above the air storage barrel 100, and the motor 105 is further installed on the mounting frame. The motor 105 is connected to the main unit 106 through a transmission connection, and the oil and gas barrel 110 is connected to the main unit 106 through an oil circuit, and an oil filter 104 is arranged on the oil circuit; an axial flow fan 109 and a cooler 107 are installed above the motor 105, and the motor 105 is connected to the frequency converter 108.
