DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0021] Reference Figure 1-3 An engine with good lubrication effect includes an engine body 3, an oil discharge pipe 9 is arranged at the bottom of the engine body 3 shell, and a quick connector 5 is fixedly arranged on the top of the side of the engine body 3 shell. The quick connector 5 is the most common air pipe type quick connector 5 in the prior art. When in use, it can be quickly connected with the air pipe of the air pump.

[0022] A accommodating cylinder 4 is fixedly arranged on the top of the quick connector 5, and a releasing assembly for quickly replacing old oil in the engine body 3 is arranged inside the accommodating cylinder 4. A top cover 41 is fixedly arranged on the top of the accommodating cylinder 4, and a protective box 2 is fixedly arranged on the side of the quick connector 5 of the engine body 3. The quick connector 5 and the end of the oil discharge pipe 9 away from the engine body 3 both extend from the inner cavity of the protective box 2.

[0023] A top plate 1 is fixedly provided on the top of the protection box 2, and the release assembly includes a switching screw 10 and a vertical column 12. The head of the switching screw 10 is rotatably connected to the top cover 41, and a corrugated head is fixedly provided on the head of the switching screw 10. The bottom of the switching screw 10 is threaded with the vertical column 12, and a threaded cavity is provided inside the vertical column 12.

[0024] A top connection hole 11 is provided at the top of the side of the vertical column 12, and a bottom connection hole 13 is provided at the bottom of the side of the vertical column 12. A connecting block 6 is fixedly provided on the outer wall of the vertical column 12, and a guide column 7 is fixedly provided at the bottom of the connecting block 6. The bottom of the guide column 7 is movably inserted into the extension block 8, and the other end of the extension block 8 is fixedly connected to the side of the engine body 3. The apertures of the top connection hole 11 and the bottom connection hole 13 are equal to the inner cavity diameters of the quick connector 5 and the oil unloading pipe 9, and the diameter of the vertical column 12 is larger than the inner cavity diameters of the quick connector 5 and the oil unloading pipe 9.
