[0045] Figure 3 yes Figure 2 The enlarged view of the structure marked as A in the figure is shown in Figure 1. Figure 3, and more specifically, in this embodiment, in order to facilitate the assembly of the connecting pipe section 100 and the injection pipe section 200, the injection pipe provided in this embodiment also includes an annular connector 300. The annular connector 300 is coaxially and detachably connected to the outer side of the second rotating connecting part 120 by means of threaded connection, and the upper end surface of the annular connector 300 is higher than the upper end surface of the second rotating connecting part 120.

That is to say, first, the first rotating connecting part 220 is inserted into the second rotating connecting part 120, and after the docking is completed, the annular connecting member 300 is screwed to the outside of the second rotating connecting part 120, and the position of the annular boss 230 is adjusted during this installation process so that it can be embedded in the annular avoidance groove 310. Through the above arrangement, it is easy to realize the connection and assembly of the first rotating connecting part 220 and the second rotating connecting part 120, and the smoothness of the relative rotation of the first rotating connecting part 220 and the second rotating connecting part 120 can be ensured.

[0046] Specifically, continue to refer to Figure 3 The first rotating connecting part 220 is rotatably inserted in the second rotating connecting part 120. The outer periphery of the first rotating connecting part 220 is provided with an annular installation groove 221. A sealing member 222 is embedded in the annular installation groove 221. The sealing member 222 abuts against the inner wall of the second rotating connecting part 120. In this embodiment, the sealing member 222 is specifically a rubber sealing ring in the prior art. In other embodiments, the sealing member 222 may also adopt other structural forms to ensure the sealing performance of the connection between the first rotating connecting part 220 and the second rotating connecting part 120. The specific structure is not limited in this embodiment.

[0047] Figure 4 yes Figure 2 A partial enlarged view of the structure marked as B. Figure 1 , Figure 2 and Figure 4 The injection tube also includes an end cover 400, which can be detachably sealed on the injection port to prevent impurities or sewage from entering the injection port when the injection tube is not in use.

[0048] Specifically, the end cap 400 includes a cover body 410 and a connecting section 420 which are coaxially connected to each other or integrally formed. The connecting section 420 is screwed to the inner wall of the liquid injection port, and the cover body 410 can cover the liquid injection port. The size of the cover body 410 is based on the ability to completely block the liquid injection port.

[0049] More specifically, refer to Figure 4 The cover body 410 is provided with an embedded annular groove 411 on one side facing the liquid injection port, and the top of the liquid injection pipe section 200 can be embedded in the embedded annular groove 411. In other words, the diameter of the cover body 410 is larger than the diameter of the liquid injection port, and by embedding the top of the liquid injection pipe section 200 in the embedded annular groove 411, the tightness of the connection between the connecting section 420 and the liquid injection port can be ensured, and the protection effect of the end cover 400 can be effectively improved.

[0050] Continue to refer to Figure 1 and Figure 2 The injection pipe also includes a base 500. The base 500 is vertically fixed or integrally formed at the bottom end of the connecting portion 110, and the base 500 is detachably connected to the engine body. The base 500 is a rectangular plate-shaped structure, and a plurality of mounting holes 510 are opened on it. The connecting bolts correspond to and penetrate the above-mentioned mounting holes 510 one by one, and are connected to the preset openings of the engine body to realize the detachable connection between the connecting pipe section 100 and the engine body.

[0051] As an option, in this embodiment, there are four mounting holes 510, which are arranged in a square array with the connecting portion 110 as the center. The engine body is provided with four preset openings, which correspond to the four mounting holes 510 one by one. The base 500 and the engine body are connected by four connecting bolts, which can improve the installation stability of the injection pipe on the engine body.

[0052] Furthermore, since the second rotating connecting portion 120 is arranged at an angle to the connecting portion 110, the opening of the second rotating connecting portion 120 is not arranged parallel to the base 500, but is arranged obliquely, and its opening direction is inclined toward a direction away from the base 500. By adjusting the correspondence between the four mounting holes 510 on the base 500 and the four preset openings on the engine body, the base 500 can be switched between four mounting states.

[0053] Specifically, in the first installation state, the opening of the second rotating connection part 120 is tilted away from the base 500 in the first direction; in the second installation state, the opening of the second rotating connection part 120 is tilted away from the base 500 in the second direction; in the third installation state, the opening of the second rotating connection part 120 is tilted away from the base 500 in the third direction; in the fourth installation state, the opening of the second rotating connection part 120 is tilted away from the base 500 in the fourth direction. The first direction is parallel to and opposite to the second direction, the third direction is perpendicular to the first direction, and the fourth direction is parallel to and opposite to the third direction. Through the above arrangement, the flexibility of the injection tube can be further improved.

[0054] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
