When the second water outlet pipe is opened, the first driving part drives the sliding plate to slide downwards to plug the first water outlet pipe, and the second driving part drives the sliding plate to slide upwards to open the second water outlet pipe. When the first water outlet pipe and the second water outlet pipe are simultaneously opened, the first driving part drives the first sliding plate to slide upwards, and the second driving part drives the second sliding plate to slide upwards so as to simultaneously close the first water outlet pipe and the second water outlet pipe, thereby being convenient for controlling the first water outlet pipe and the second water outlet pipe to be independently opened or simultaneously opened.

Referring to fig. 4 and 5, a first spool 381 and a second spool 382 are fixedly connected to one end of the slide bar 38, which is close to the first hinge plate 43 and the second hinge plate 45, and a spring 39 acts on the slide bar 38 to drive the slide bar 38 to slide the first spool 381 and the second spool 382 into the driving cavity 35 after sliding, and the end of the first spool 381 and the end of the second spool 382, which are far away from the slide bar 38, are arc-shaped.
Referring to FIG. 3, a first spool 381 is located below the first hinge plate 43, a second spool 382 is located below the second hinge plate 45, and both the first spool 381 and the second spool 382 are located above the hinge shafts of the first hinge plate 43 and the second hinge plate 45. The length of spool one 381 extending into drive chamber 35 is less than the length of spool two 382 extending into drive chamber 35.
Referring to fig. 3 and 5, the side walls of the hinge plates one 43 and two 45 facing the slide bar 38 are provided with a clamping groove 47 for clamping the slide post one 381 and the slide post two 382, so that the hinge plates one 43 and two 45 are driven to rotate by the rotation of the screw posts one 44 and two 46, the slide post one 381 and two 382 slide into the end cover 3 to drive the slide bar 38 to slide, and the spring 39 pushes the slide bar 38 to clamp the slide post one 381 and the slide post two 382 into the clamping groove 47. When the first slide post 381 and the second slide post 382 are clamped in the clamping groove 47, the first hinge plate 43 drives the first slide plate 41 to rotate away from the first water outlet pipe 31, and the second hinge plate 45 drives the second slide plate 42 to rotate away from the second water outlet pipe 32.
Referring to fig. 5 and 6, an oil storage cavity 5 located above the slide rod 38 is formed in the end cover 3, the oil storage cavity 5 is used for storing lubricating oil, a lubricating oil duct 51 communicated with the outer ring of the bearing 34 in the vertical direction is formed in the end cover 3, a sliding path of the slide rod 38 passes through the lubricating oil duct 51, and a through hole 383 communicated with the lubricating oil duct 51 is formed in the slide rod 38. When the first spool 381 is abutted by the first hinge plate 43 and the second spool 382 is abutted by the second hinge plate 45, the sliding rod 38 is driven to slide in a direction away from the first hinge plate 43 and the second hinge plate 45, so that the through hole 383 on the sliding rod 38 is briefly communicated with the lubricating oil duct 51, and the lubricating oil in the oil storage cavity 5 flows into the outer ring of the bearing 34 after passing through the lubricating oil duct 51 and the through hole 383, so as to lubricate the bearing 34. After the first slide post 381 and the second slide post 382 are clamped in the clamping groove 47, the spring 39 pushes the slide rod 38 to reset, so that the through holes 383 and the lubricating oil duct 51 are staggered, and the lubricating oil is prevented from continuing to flow downwards.
The implementation principle of the high-efficiency low-noise self-priming pump provided by the embodiment of the application is as follows: when the self-priming pump is used, the screw thread post I44 or the screw thread post II 46 is screwed to drive the hinge plate I43 or the hinge plate II 45 to rotate, so that the slide post I381 or the slide post II 382 is extruded to push the slide rod 38 to slide in a direction away from the hinge plate I43, and the through hole 383 is communicated with the lubricating oil duct 51 to guide lubricating oil into the bearing 34. After the first slide post 381 or the second slide post 382 is clamped in the clamping groove 47, the first hinge plate 43 drives the first slide plate 41 to slide away from the first water outlet pipe 31 or the second hinge plate 45 drives the second slide plate 42 to slide away from the second water outlet pipe 32, so that the first water outlet pipe 31 or the first water outlet pipe 31 can be independently or completely opened. So that the motor 2 can conveniently drive the impeller 22 to rotate, a small part of water in the pump body 1 is thrown out from the first water outlet pipe 31 or the second water outlet pipe 32, and negative pressure is generated on the first water inlet pipe 11 to suck the water to form self-suction. The water flowing out flows along the horizontal direction, so that the compression on the water pipes connected to the first water outlet pipe 31 and the second water outlet pipe 32 is reduced, and the water outlet efficiency of the self-priming pump is further improved in a water outlet mode of being divided into two parts.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
