[0023] like Figure 1-5As shown, a novel double-inlet and double-outlet water pump comprises an upper cover 1, a second umbrella 2, a first umbrella 3, a third umbrella 21, a fourth umbrella 22, a valve plate 4, a first leather cup 5, a second leather cup 6, a cylinder body 7, a bottom cover 8 and a driving assembly 9. The upper cover 1, the valve plate 4, the cylinder body 7 and the bottom cover 8 are arranged in sequence from top to bottom. The first leather cup 5 and the second leather cup 6 are both installed in the bottom cover 8, and their movable cylinders 10 are connected to each other. The driving assembly 9 is installed on the bottom cover 8 and is in driving connection with the first leather cup 5 and the second leather cup 6. The top of the upper cover 1 is extended upwardly to be provided with a first liquid inlet pipe 11 and a second liquid outlet pipe 12, and one side thereof is extended laterally outwardly to be provided with a second liquid inlet pipe 13 and a first liquid outlet pipe 14. The valve plate 4 is provided with a first liquid outlet 41, a second liquid outlet 42, a first liquid inlet 43 and a second liquid inlet 44. The first liquid inlet pipe 11, the first liquid inlet port 43 and the movable cylinder 10 of the second leather cup 6 are interconnected, and the movable cylinder 10 of the second leather cup 6, the first liquid outlet port 41 and the first liquid outlet pipe 14 are interconnected. The second liquid inlet pipe 13, the second liquid inlet port 44 and the movable cylinder 10 of the first leather cup 5 are interconnected, and the movable cylinder 10 of the first leather cup 5, the second liquid outlet port 42 and the second liquid outlet pipe 12 are interconnected. The first umbrella 3, the second umbrella 2, the third umbrella 21 and the fourth umbrella 22 are respectively movably installed in the valve plate 4 and movably covered on the corresponding first liquid outlet port 41, the second liquid outlet port 42, the first liquid inlet port 43 and the second liquid inlet port 44.

[0024] In this embodiment, Figure 3 As shown, it also includes a sealing gasket 15, which is installed in the top surface of the valve plate 4 to ensure the sealing performance of the water pump as a whole.

[0025] Specifically, Figure 3 As shown, the valve plate 4 is provided with a first plug hole 45, a second plug hole 46, a third plug hole 47 and a fourth plug hole 48, and the first plug hole 45, the second plug hole 46, the third plug hole 47 and the fourth plug hole 48 are respectively arranged on one side of the corresponding first liquid outlet 41, the second liquid outlet 42, the first liquid inlet 43 and the second liquid inlet 44. The roots of the first umbrella 3, the second umbrella 2, the third umbrella 21 and the fourth umbrella 22 are respectively movably inserted in the corresponding first plug hole 45, the second plug hole 46, the third plug hole 47 and the fourth plug hole 48, and the umbrella surfaces of the first umbrella 3 and the second umbrella 2 are arranged toward the inside of the upper cover 1; the umbrella surfaces of the third umbrella 21 and the fourth umbrella 22 are arranged toward the inside of the movable cylinder 10.

[0026] In this embodiment, Figures 1 to 4As shown, it also includes a rubber plug 16, which is sleeved on the outer side of the first liquid inlet pipe 11 and the second liquid outlet pipe 12 of the upper cover 1, and is provided with a third liquid inlet 17 and a third liquid outlet 18 connected to the first liquid inlet pipe 11 and the second liquid outlet pipe 12, so as to ensure the stability of liquid inlet and liquid outlet at the top of the upper cover 1 and improve the stability of the water pump.

[0027] In this embodiment, Figure 3 and Figure 4 As shown, the driving assembly 9 includes a motor 91, an eccentric wheel 92, a swing frame 93, a steel needle 94 and a steel ball 95. The motor 91 is mounted on the bottom end of the bottom cover 8, and its output shaft extends into the bottom cover 8. The eccentric wheel 92 is mounted on the output shaft of the motor 91. The steel ball 95 is mounted in the eccentric wheel 92. One end of the steel needle 94 is tiltedly mounted in the eccentric wheel 92 and contacts the steel ball 95, and the other end extends upward from the eccentric wheel 92. The swing frame 93 is mounted on the end of the steel needle 94 that extends upward. The bottom ends of the first leather cup 5 and the second leather cup 6 are mounted in the swing frame 93. Among them, a placement groove 96 is tiltedly opened in the eccentric wheel 92, and the steel ball 95 is mounted in the placement groove 96. One end of the steel needle 94 is tiltedly mounted in the placement groove 96, so that the installation of the steel needle 94 and the steel ball 95 is more stable and reliable. The two ends of the swing frame 93 are respectively provided with connection holes 97, and the bottom ends of the first leather cup 5 and the second leather cup 6 are respectively installed in the corresponding connection holes 97. The swing frame 93 is tilted, and when it rotates, it drives the first leather cup 5 and the second leather cup 6 to move up and down. When the first leather cup 5 moves upward, the second leather cup 6 moves downward, and when the first leather cup 5 moves downward, the second leather cup 6 moves upward, so that the movement of the first leather cup 5 and the second leather cup 6 is more stable.

[0028] In this embodiment, Figure 3 As shown, it also includes a first fixing screw 19, which passes through the bottom surface of the bottom cover 8 and is locked with the motor 91, so that the motor 91 is locked and fixed on the bottom cover 8, making the assembly of the motor 91 and the bottom cover 8 more stable and reliable. Specifically, it also includes a second fixing screw 20, which passes through the upper cover 1, the valve plate 4, and the cylinder body 7 in sequence and is locked with the bottom cover 8, so that the upper cover 1, the valve plate 4, the cylinder body 7 and the bottom cover 8 are locked and fixed, making the assembly of the upper cover 1, the valve plate 4, the cylinder body 7 and the bottom cover 8 more stable and reliable.

[0029] When the water pump is powered on, the motor 91 rotates to drive the eccentric wheel 92 to rotate, and the eccentric wheel 92 then drives the first leather cup 5 and the second leather cup 6 to move through the swing frame 93. When the first leather cup 5 moves downward, the liquid pushes the fourth umbrella 22 away, and the second umbrella 2 and the valve plate 4 are in a close sealing state. The movable cylinder 10 of the first leather cup 5 generates suction to draw the liquid into the movable cylinder 10 of the first leather cup 5 through the second liquid inlet pipe 13. When the first leather cup 5 moves upward, the liquid pushes the second umbrella 2 away, and the fourth umbrella 22 and the valve plate 4 are in a close sealing state, squeezing the liquid in the movable cylinder 10 of the first leather cup 5 out and flowing out from the second liquid outlet pipe 12. When the second leather cup 6 moves downward, the liquid pushes the third umbrella 21 away. At this time, the first umbrella 3 and the valve plate 4 are in a fitted and sealed state. The movable cylinder 10 of the second leather cup 6 generates suction to draw the liquid into the movable cylinder 10 of the second leather cup 6 through the first liquid inlet pipe 11. When the second leather cup 6 moves upward, the liquid pushes the first umbrella 3 away. At this time, the third umbrella 21 and the valve plate 4 are in a fitted and sealed state, squeezing the liquid in the movable cylinder 10 of the second leather cup 6 out and flowing out from the first liquid outlet pipe 14.

[0030] The present invention has a simple structure and strong practicality, realizes double inlet and double outlet of liquid in a water pump, improves working efficiency to meet use requirements, reduces the overall volume of the water pump, and is economical and practical.

[0031] The above does not limit the technical scope of the present invention in any way. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
