[0002] Impeller pumps are commonly used fluid conveying equipment in modern life because of their good head. Impeller pumps are used in environments where their water inlet is lower than the source water level. Impeller pumps generally have a water inlet and a water outlet, a water pumping chamber inside, and an impeller inside the water pumping chamber. The output shaft of the drive motor drives the impeller to rotate, pumping the liquid from the water pumping chamber to the water outlet, and then transporting it to other equipment or pipelines.

[0003] If the source water level is lower than the water inlet end of the impeller pump, the liquid cannot enter the pumping chamber of the impeller pump, and the impeller pump cannot work well.

[0025] Example

[0026] An impeller pump with a water suction function comprises a pump head body 01, wherein an inlet waterway, an outlet waterway and a pumping chamber 40 are arranged in the pump head body 01, and a water pumping assembly located in the pumping chamber 40 is arranged in the waterway where the inlet waterway and the outlet waterway are connected, and further comprises a bidirectional driving motor 08 and a water suction mechanism, wherein one end of the output shaft 07 of the double-head driving motor provides power for the water pumping assembly to pump water to the outlet waterway, and the other end provides power for the water suction mechanism to absorb water and transport it to the inlet waterway.

[0027] In this embodiment, Figure 1 As shown, on the basis of the impeller pump, a bidirectional driving motor 08 and a water suction mechanism are provided, and the two ends of the output shaft 07 of the double-headed driving motor provide power for the water pumping assembly and the water suction mechanism respectively. When the liquid level is low and the liquid cannot enter the water pumping chamber 40, the bidirectional driving motor 08 works, and the water suction mechanism sucks the water and transports it to the water inlet waterway, and then enters the water pumping chamber 40 from the water inlet waterway, and finally the water pumping assembly pumps the water in the water pumping chamber 40 to the water outlet waterway. In this solution, when the liquid level is low and cannot enter the water pumping chamber 40, the water suction mechanism can suck the water and transport it to the water pumping chamber 40, thereby ensuring that the impeller pump can perform normal water pumping operations.

[0028] Furthermore, the water inlet waterway includes a first water inlet channel 04 and a second water inlet channel 02 which are connected to each other, a second sealing plate 03 is provided at the intersection of the second water inlet channel 02 and the first water inlet channel 04, the water outlet waterway includes a first water outlet waterway and a second water outlet waterway which are connected to the pump water chamber 40, the pump water chamber 40 is connected to the second water inlet channel 02, and also includes a water control component for switching the first water outlet waterway and the second water outlet waterway to opposite on and off states under the action of the outlet water pressure.

[0029] Furthermore, the first water outlet waterway includes a first water outlet channel 43 and a first water outlet 44, and the second water outlet waterway includes a second water outlet channel 48 and a second water outlet 51. Under the action of the internal water pressure of the first water outlet channel 43 and the second water outlet channel 48, the water control component switches the waterway between the first water outlet channel 43 and the first water outlet 44 and the waterway between the second water outlet channel 48 and the second water outlet 51 to opposite on and off states.

[0030] Furthermore, a connecting plate 52 protruding outward is provided on one side of the pump head body 01, and a cover plate 38 is sealed to one side of the connecting plate 52. A first sealing ring 36 is pressed between the connecting plate 52 and the cover plate 38. A water flow cavity 37 connected to the first water outlet waterway and the second water outlet waterway is formed between the cover plate 38 and the connecting plate 52. The water control component is located in the water flow cavity 37 and is movably connected to the connecting plate 52. Under the action of the internal water pressure of the first water outlet channel 43 and the second water outlet channel 48, the water control component rotates and switches the water path between the first water outlet channel 43 and the first water outlet 44 and the water path between the second water outlet channel 48 and the second water outlet 51 to be in opposite on and off states.

[0031] Furthermore, the water control component includes a water sealing plate 39, and a rotating shaft 35 is provided on both sides of the middle part of the water sealing plate 39. The water sealing plate 39 is provided with a first sealing gasket 47, a second sealing gasket 45, a third sealing gasket 50, and a fourth sealing gasket 49 corresponding to the first water outlet 44, the first water outlet channel 43, the second water outlet channel 48, and the second water outlet 51. The water sealing plate 39 is in an obtuse V shape, and the rotating shaft 35 is located in the rotating cavity 46 between the connecting plate 52 and the cover plate 38, and the rotating shaft 35 and the cover plate 38 and the connecting plate 52 can rotate relative to each other.

[0032] Specifically, a U-shaped connecting plate 52 is integrally formed on the right side of the pump head, and the connecting opening faces right. The cover plate 38 is adaptably connected to the connecting plate 52. The cover plate 38 is a door-shaped structure. The left end of the cover plate 38 is inserted into the U-shaped cavity of the connecting plate 52. A rotating cavity 46 adapted to the rotating shaft 35 can be formed between the left end of the cover plate 38 and the connecting plate 52. The rotating shaft 35 is rotatably arranged in the rotating cavity 46. Since the water sealing plate 39 is in an obtuse V-shape, under the action of the internal water pressure of the first water outlet channel 43 and the second water outlet channel 48, the water sealing plate 39 can rotate clockwise or counterclockwise with the rotating shaft 35 as the axis, thereby switching the first water outlet waterway and the second water outlet waterway to opposite water flow and water cut-off states.

[0033] Furthermore, when the water pressure in the first water outlet channel 43 is greater than the water pressure in the second water outlet channel 48, the water sealing plate 39 rotates clockwise, the water path between the first water outlet channel 43 and the first water outlet 44 is connected, and the water path between the second water outlet channel 48 and the second water outlet 51 is blocked by the third sealing gasket 50 and the fourth sealing gasket 49; when the water pressure in the first water outlet channel 43 is less than the water pressure in the second water outlet channel 48, the water sealing plate 39 rotates counterclockwise, the water path between the first water outlet 44 and the first water outlet channel 43 is blocked by the first sealing gasket 47 and the second sealing gasket 45, and the water path between the second water outlet channel 48 and the second water outlet 51 is connected.

[0034] Furthermore, a base 34 is provided on the pump head body 01, and a water pumping chamber 40 is formed between the base 34 and the inner wall of the pump head body 01. A bidirectional driving device is connected to the top surface of the base 34. The output shaft 07 of the bidirectional driving motor 08 passes downward through the base 34 and is connected to the water pumping assembly. The output shaft 07 rotates clockwise or counterclockwise to drive the water pumping assembly to rotate accordingly. The water pumping assembly rotates clockwise or counterclockwise to pump water toward the first water outlet 44 or the second outlet.

[0035] Furthermore, the water pump assembly includes a rotating seat 41 and blades. The rotating seat 41 is connected to the lower end of the output shaft 07. The impeller is evenly distributed in a ring shape around the rotating seat 41. The bottom surface of the base 34 is embedded with a second sealing ring 33 located on the outside of the output shaft 07. The output shaft 07 is sleeved with a third sealing ring located below the rotating seat 41. The bottom surface of the base 34 is provided with a groove, and a fourth sealing ring 05 is embedded in the groove. The fourth sealing ring 05 is pressed between the base 34 and the pump head body 01.

[0036] Based on the existing impeller pump, improvements have been made to the impeller pump itself. When it is necessary to transport fluid to different waterways or equipment, it is necessary to add multiple waterway switching valves to the outlet waterway of the impeller pump to achieve the delivery of fluid to different waterways or equipment. This requires the addition of additional valves, making the pipeline more complicated and the cost of use higher.

[0037] Specifically, if Figure 1 and Figure 2 As shown, water is sucked in by the water absorption mechanism and then transported to the first water inlet channel 04, and then enters the water pump chamber 40 through the second water inlet channel 02. The first water outlet 44 and the second water outlet 51 are connected to different devices or waterways. When the bidirectional drive motor 08 is working, when the output shaft 07 of the motor rotates clockwise, the rotating seat 41 drives the blades to rotate clockwise, and the water in the water pump chamber 40 is transported to the first water outlet channel 43. The amount of water in the first water outlet channel 43 is much greater than the amount of water in the second water outlet channel 48. At this time, the water pressure in the first water outlet channel 43 is greater than the water pressure in the second water outlet channel 48. The water pressure in the first water outlet channel 43 pushes the water sealing plate 39 to the right, sealing the water. The plate 39 rotates clockwise with the rotating shaft 35 as the axis, and the first sealing gasket 47 and the second sealing gasket 45 release the seal on the water outlet end of the first water outlet channel 43 and the water inlet end of the first water outlet 44. At this time, the water passage chamber 37 connects the water path between the first water outlet channel 43 and the first water outlet 44, and water is pumped from the first water outlet 44 to the designated equipment or water path. After the water sealing plate 39 rotates clockwise by a certain angle, the third sealing gasket 50 and the fourth sealing gasket 49 seal the water outlet end of the second water outlet channel 48 and the water inlet end of the second water outlet 51. In this way, the water sealing plate 39 switches the first water outlet water path to be connected and the second water outlet water path to be blocked under the action of the internal water pressure of the first water outlet channel 43.

[0038] On the contrary, when the output shaft 07 of the motor rotates counterclockwise, the water in the pump water chamber 40 is transported to the second water outlet channel 48. The amount of water in the first water outlet channel 43 is much smaller than the amount of water in the second water outlet channel 48. At this time, the water pressure in the first water outlet channel 43 is smaller than the water pressure in the second water outlet channel 48. The water pressure in the second water outlet channel 48 pushes the water sealing plate 39 to the right. The water sealing plate 39 rotates counterclockwise with the rotating shaft 35 as the axis. The third sealing gasket 50 and the fourth sealing gasket 49 release the seal on the water outlet end of the second water outlet channel 48 and the water inlet end of the second water outlet 51. At this time, the water chamber 37 is connected to the water inlet end of the second water outlet channel 48. The waterway between the second water outlet channel 48 and the second water outlet 51, the first sealing gasket 47 and the second sealing gasket 45 seal the water inlet end of the first water outlet 44 and the water outlet end of the first water outlet channel 43, and the water is pumped from the second water outlet 51 to the designated equipment or waterway. After the water sealing plate 39 rotates counterclockwise by a certain angle, the second sealing gasket 45 and the first sealing gasket 47 seal the water outlet end of the first water outlet channel 43 and the water inlet end of the first water outlet 44, so that the water sealing plate 39 switches the first water outlet waterway to be blocked and the second water outlet waterway to be connected under the action of the internal water pressure of the second water outlet channel 48. When it is necessary to pump water to different equipment or waterways, it is only necessary to change the water pressure in the first water outlet channel 43 and the second water outlet channel 48 by the forward and reverse rotation of the motor, and then the water outlet waterway can be switched by rotating the water sealing plate 39, without adding an additional waterway switching valve on the water outlet waterway, thereby optimizing the waterway connection structure and reducing the use cost.

[0039] Furthermore, the water absorption mechanism includes a shell 18, an eccentric assembly, a partition 32, and a support plate 15. The support plate 15 is connected to the housing 06 of the bidirectional drive motor 08. The partition 32 is arranged between the shell 18 and the support plate 15. The shell 18 is provided with a water inlet 28, a water inlet cavity 31, a water outlet cavity 27, a third water outlet channel 26, and a fourth water outlet channel 19. The fourth water outlet channel 19 is connected to the first water inlet channel 04 through a connector 11. The water inlet 28 is connected with the water inlet chamber 31, the water outlet chamber 27 is connected with the third water outlet channel 26, and a backflow prevention member is provided on the water path connecting the third water outlet channel 26 with the fourth water outlet. A boosting diaphragm 14 is provided between the partition 32 and the support plate 15, and a boosting chamber 16 is formed between the boosting diaphragm 14 and the partition 32. The lower end of the boosting diaphragm 14 is connected with the eccentric assembly, and a one-way water flow structure is provided on the water path connecting the boosting chamber 16 with the water outlet chamber 27.

[0040] Furthermore, a first sealing plate 21 is provided at the intersection of the third water outlet channel 26 and the fourth water outlet channel 19, the eccentric assembly includes a spring 22 and a sealing plug 23, and a water sealing port 24 connected to the third water outlet channel 26 is formed in the shell 18. One end of the spring 22 acts on the sealing plate, and the other end acts on the sealing plug 23. The sealing plug 23 seals or connects the water path at the water sealing port 24 under the combined action of the water pressure in the fourth water outlet channel 19 and the water pressure in the third water outlet channel 26.

[0041] Specifically, Figure 1 As shown, the water suction mechanism is actually a diaphragm pump, which provides things for the impeller pump and the diaphragm pump at the same time through the two-way drive motor 08, and the diaphragm pump can have the effect of absorbing water. The fourth water outlet channel 19 is connected to the first water inlet channel 04 through the connector 11, and a fifth sealing ring 10 is provided at the connection. A fifth sealing gasket 25 is pressed between the partition 32 and the inner wall of the shell 18. The partition 32 is provided with a water inlet hole 20 and a water outlet hole 29 connected to the boost chamber 16, and a water inlet check valve flap 17 is fixed on one side of the water inlet hole 20, and a water outlet check valve flap 30 is fixed on one side of the water outlet hole 29. The upper end of the output shaft 07 of the two-way drive motor 08 is connected to the eccentric assembly, and the eccentric assembly includes an eccentric seat 09, a connecting rod 12 and a push frame 13. The eccentric assembly is a conventional setting in existing diaphragm pumps. The eccentric seat 09 is connected to the output shaft 07 is connected at the upper end, the lower end of the connecting rod 12 is eccentrically connected to the eccentric seat 09, the upper end is connected to the push frame 13, one end of the push frame 13 is connected to the lower end of the boosting diaphragm 14, the output shaft 07 rotates through the eccentric assembly to drive the boosting diaphragm 14 to reciprocate and squeeze the boosting chamber 16, thereby producing water absorption and pumping effects, water is sucked into the water inlet chamber 31 from the water inlet 28, and then pushes open the water inlet one-way valve flap 17 to enter the boosting chamber 16 through the water inlet hole 20, when the volume of the boosting chamber 16 is reduced, the water in the boosting chamber 16 is pressed out from the water outlet hole 29 and pushes open the water outlet one-way valve flap 30 to enter the water outlet chamber 27, and enters the third water outlet channel 26, the water pressure pushes open the seal 23, the water path at the water sealing port 24 is connected, the water enters the fourth water outlet channel 19 and is transported to the first water inlet channel 04, and finally the water pumping assembly completes the water pumping operation. If the water pressure in the fourth water outlet channel 19 is greater than the water pressure in the third water outlet channel 26 , the sealing plug 23 seals the water sealing port 24 under the action of the spring 22 and the water pressure in the fourth water outlet channel 19 to prevent the water in the fourth water outlet channel 19 from flowing back.
