The invention provides an oil pumping unit which is switched to a third air port to be communicated with a second air port when oil in a second tank body needs to be discharged, an external air source is used for filling the second tank body, and the oil in the second tank body is pressed out of a system through an oil discharge port to finish oil discharge.
The first tank can be called a pumping unit measuring cup. The utility model with the publication number of CN205679290U discloses a measuring cup of an oil pumping unit, which comprises a measuring cup body with openings at two ends, an upper end cover, a lower end cover and a central tube, wherein the upper end cover is covered on one end of the measuring cup body, the lower end cover is covered on the other end of the measuring cup body, the central tube is arranged on the upper end cover, the measuring cup body and the lower end cover in a penetrating way, and the axis of the central tube and the axis of the measuring cup body are positioned on the same straight line; an oil hole is formed in the pipe wall of the central pipe, which is close to the lower end cover, and the oil hole is positioned in the measuring cup body; one end of the central tube is provided with a vacuum generator and an oil pumping connecting tube. The oil discharge port of the existing oil pumping connecting pipe is arranged adjacent to the air suction port of the vacuum generator, so that the oil is easily sprayed under the influence of air flow entering the cup body of the measuring cup and being influenced by the air suction port of the vacuum generator.
Disclosure of Invention
For overcoming the not enough among the above-mentioned prior art, the utility model aims to provide a pneumatic oil spout structure of preventing that connects the waste oil machine of taking out.
In order to achieve the above objects and other related objects, the present invention provides a technical solution: an oil injection prevention structure of a pneumatic pumping and connecting waste oil machine is characterized in that an oil pumping connecting pipe of the pneumatic pumping and connecting waste oil machine is communicated with an oil injection prevention pipe, the oil injection prevention pipe comprises a straight pipe section and a curved pipe section which are connected with each other, the straight pipe section is horizontally arranged, an outlet of the straight pipe section is not arranged towards an air suction port of a vacuum generator, an avoidance hole is formed in a central pipe of the pneumatic pumping and connecting waste oil machine, and the straight pipe section penetrates through the avoidance hole; the curved pipe section is communicated with the oil pumping connecting pipe.
Because of the application of the technical scheme, compared with the prior art, the utility model the advantage that has is:
the utility model discloses an add on the oil pumping connecting pipe and establish a fuel spray prevention pipe, and fuel spray prevention pipe's export does not set up towards vacuum generator's extraction opening for vacuum generator's the air current of extraction opening does not exert an influence to the oil feed of the oil pumping connecting pipe in the graduated flask cup, thereby can not produce the oil spout phenomenon.

Fig. 2 is a schematic cross-sectional view of the present invention.
In the above drawings, 1, an oil spray prevention pipe; 2. an oil pumping connecting pipe; 3. a straight pipe section; 4. a curved pipe section; 5. balancing the air pipe; 6. avoiding holes; 7. a central tube.
Detailed Description
The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.
Please refer to fig. 1-2. It should be understood that the structure, ratio, size and the like shown in the drawings attached to the present specification are only used for matching with the content disclosed in the specification, so as to be known and read by those skilled in the art, and are not used for limiting the limit conditions that the present invention can be implemented, so that the present invention has no technical essential meaning, and any structure modification, ratio relationship change or size adjustment should still fall within the scope that the technical content disclosed in the present invention can cover without affecting the function that the present invention can produce and the purpose that the present invention can achieve. Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for convenience of description, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof may be made without substantial technical changes, and the present invention is also regarded as the scope of the present invention.
Referring to the attached drawings 1-2, an oil injection prevention structure of a pneumatic oil pumping and connecting waste oil machine is disclosed, wherein an oil pumping connecting pipe 2 of the pneumatic oil pumping and connecting waste oil machine is communicated with an oil injection prevention pipe 1, the oil injection prevention pipe comprises a straight pipe section 3 and a curved pipe section 4 which are connected with each other, the straight pipe section is horizontally arranged, an outlet of the straight pipe section is not arranged towards an air extraction opening which does not face a vacuum generator, a central pipe 7 of the pneumatic oil pumping and connecting waste oil machine is provided with an avoidance hole 6, and the straight pipe section passes through the avoidance hole; the curved pipe section is communicated with the oil pumping connecting pipe.
