[0029] Please see Figures 1-3 The impeller pump 100 of this application includes a first housing 10, a second housing 20 disposed opposite to the first housing 10, a stator 30, a rotor 40 and an impeller 50. The second housing 20 has an inlet 21 and a drain outlet 22 communicating with the inlet 21. The stator 30 is disposed in the first housing 10. The first end of the rotor 40 is inserted into the stator 30 and the rotor 40 is coaxially disposed with the stator 30. The impeller 50 is disposed in the second housing 20 and is connected to the second end of the rotor 40.

[0030] In the impeller pump 100 of this application embodiment, the first housing 10 and the second housing 20 are arranged opposite to each other, which facilitates the disassembly and assembly of the first housing 10 and the second housing 20, and thus facilitates the cleaning of the components inside the second housing 20. In addition, the first end of the rotor 40 is inserted into the stator 30, which can reduce the length dimension of the impeller 50, making the impeller pump 100 compact and small in size.

[0031] Specifically, the first housing 10 and the second housing 20 are arranged opposite to each other, meaning that the second housing 20 is partially inserted into the first housing 10, and the second housing 20 and the first housing 10 are not in direct contact.

[0032] The first housing 10 and the second housing 20 can be made of materials such as metal and plastic, combined Figure 4 and Figure 5 The first housing 10 has a receiving cavity 11, and the stator 30 is disposed in the receiving cavity 11. The second housing 20 has a receiving cavity 23, and the rotor 40 and impeller 50 are disposed in the receiving cavity 23. The receiving cavity 23 is connected to the water inlet 21 and the water outlet 22.

[0033] The inlet 21 and outlet 22 can be in regular shapes such as circles and squares, or they can be irregular shapes. The outlet 22 can be connected to a pipe to transport liquid to the desired location through the pipe. In order to facilitate the connection between the outlet 22 and the pipe, the shape of the outlet 22 can be the same as the shape of the pipe. In the embodiments of this application, in order to facilitate the formation, manufacturing and / or connection with common pipes, the outlet 22 is circular.

[0034] The rotor 40 and stator 30 are coaxial, meaning that the central axis of the rotor 40 and the central axis of the stator 30 are on the same straight line.

[0035] Please see Figure 5 In some embodiments, the stator 30 includes a plurality of coil windings 31 arranged at circumferential intervals along the first housing 10.

[0036] In this way, multiple coil windings 31 can form a magnetic field in the circumference of the first housing 10, driving the rotor 40 to rotate through magnetic attraction.

[0037] Specifically, the stator 30 includes multiple stator teeth, which are arranged at intervals along the circumference of the first housing 10. Coils are wound around the stator teeth to form coil windings 31. The number of coil windings 31 can be 2, 3, 4, 5 or more. When the first housing 10 is circular, the multiple coil windings 31 can be arranged in a circular arrangement. When the first housing 10 is square, the multiple coil windings 31 can be arranged in a square arrangement. The distance between each coil winding 31 and the two adjacent coil windings 31 is the same.

[0038] Please see Figure 2 In some embodiments, the rotor 40 includes a shaft 41 and a permanent magnet 42 disposed on the shaft 41. The permanent magnet 42 is inserted into the coil winding 31, and the impeller 50 is disposed at the end of the shaft 41 away from the permanent magnet 42.

[0039] Thus, the permanent magnet 42 and the magnetic poles of the coil winding 31 drive the permanent magnet 42 to rotate through the repulsion of like poles and the attraction of unlike poles, which in turn drives the rotating shaft 41 and the impeller 50 to rotate.

[0040] Specifically, the permanent magnet 42 can be disposed on the surface of the first end of the rotor 40, so that the permanent magnet 42 can be inserted into the coil winding 31 of the stator 30, and the impeller 50 can be disposed at the second end of the rotor 40, so that the rotating shaft 41 can be connected to the impeller 50, thereby driving the impeller 50 to move through the rotating shaft 41.

[0041] When in use, the coil winding 31 is energized. When the coil winding 31 is energized, a magnetic field is generated. This magnetic field interacts with the magnetic field of the permanent magnet 42. When the coil winding 31 is energized and becomes an electromagnet, it will have N and S poles. The N and S poles of the permanent magnet 42 are fixed. According to the principle of like poles repelling and unlike poles attracting, the S pole of the permanent magnet 42 will be attracted by the N pole of the coil winding 31, and the N pole of the permanent magnet 42 will be repelled by the N pole of the coil winding 31. This forms a tangential force component, which drives the permanent magnet 42 to rotate and drives the shaft 41 to rotate. During the rotation of the shaft 41, the impeller 50 will rotate. The centrifugal force generated by the high-speed rotating impeller 50 will throw the liquid out, thereby realizing the liquid transportation.

[0042] The magnetic field strength can be adjusted by regulating the current in the coil winding 31, thereby regulating the rotational speed of the impeller 50. The permanent magnet 42 can be equidistant from each coil winding 31 so that the magnetic attraction between each coil winding 31 and the permanent magnet 42 is equal.

[0043] Please see Figure 2 In some embodiments, the rotating shaft 41 and the impeller 50 are an integral structure.

[0044] Thus, by rotating the permanent magnet 42, the rotating shaft 41 can be driven to rotate, thereby driving the impeller 50 to rotate and realizing the transport of liquid.

[0045] Specifically, the axial direction of the impeller 50 can be the same as that of the shaft 41. The shaft 41 and the impeller 50 can be integrally formed or mechanically connected to form an integral structure. For example, the shaft 41 and the impeller 50 can be integrally formed by injection molding or by stamping; or, for example, the shaft 41 and the impeller 50 can be integrally formed by welding, bonding or other methods.

[0046] Please see Figure 4 and Figure 5 In some embodiments, the second housing 20 includes a first mounting portion 24 and a second mounting portion 25 detachably connected to the first mounting portion 24. The first mounting portion 24 has an inlet 21 and a drain 22. The impeller 50 is disposed in the first mounting portion 24, and the first end of the rotor 40 is disposed in the second mounting portion 25. The second mounting portion 25 is inserted into the first housing 10.

[0047] Thus, the first mounting part 24 and the second mounting part 25 are detachably connected, which facilitates the disassembly and assembly of the components inside the second housing 20 and improves the convenience of maintaining the impeller pump 100.

[0048] Specifically, the first mounting portion 24 and the second mounting portion 25 can be connected by a snap-fit ​​connection or by fasteners such as screws and bolts. In one embodiment, a sealing ring is provided at the connection point between the first mounting portion 24 and the second mounting portion 25. The sealing ring enables a sealed connection between the first mounting portion 24 and the second mounting portion 25, allowing liquid to drain from the drain port 22 and reducing the risk of liquid leakage from the connection point. The sealing ring can be provided on either the first mounting portion 24 or the second mounting portion 25.

[0049] Please see Figure 2 In some embodiments, the impeller pump 100 includes a connecting shaft 60, which passes through the rotor 40 and the impeller 50, with both ends of the connecting shaft 60 mounted on the first mounting portion 24 and the second mounting portion 25, respectively.

[0050] Thus, the connecting shaft 60 can provide support for the rotor 40 and the impeller 50, allowing the rotor 40 and the impeller 50 to be rotatably mounted on the second housing 20.

[0051] Specifically, the axial direction of the connecting shaft 60 can be the same as that of the rotor 40 and the impeller 50. The connecting shaft 60 passes through the rotor 40 and the impeller 50 along the axial direction. The end of the connecting shaft 60 near the first housing 10 can be fixed on the side wall of the second mounting part 25 near the first housing 10. A support member 26 is formed on the side of the first mounting part 24 away from the first housing 10. The support member 26 can be integrally formed with the first mounting part 24. The support member 26 has a mounting hole. The end of the connecting shaft 60 away from the first housing 10 can be inserted into the mounting hole. The rotor 40 and the impeller 50 can rotate relative to the connecting shaft 60.

[0052] Please see Figure 1 In some embodiments, the axial direction of the inlet 21 is perpendicular to the axial direction of the outlet 22.

[0053] In this way, the direction of liquid flow can be changed, thereby enabling the liquid to be transported in different directions.

[0054] For example, the axial direction of the inlet 21 is horizontal, and the axial direction of the outlet 22 is vertical, perpendicular to the axial direction of the inlet 21; or, for another example, the axial direction of the inlet 21 is horizontal, and the axial direction of the outlet 22 is horizontal, perpendicular to the axial direction of the inlet 21.

[0055] In one embodiment, the inlet 21 is axially horizontal, the outlet 22 is axially vertical and extends vertically upward from the horizontal plane where the inlet 21 is located, thus enabling the liquid to be transported from a low place to a high place.

[0056] Please see Figure 1 and Figure 2In some embodiments, the impeller 50 is arranged radially along the axial direction of the drain outlet 22.

[0057] In this way, the liquid can be discharged from the drain outlet 22 along the axial direction of the drain outlet 22 under the action of the centrifugal force of the impeller 50.

[0058] Specifically, the inlet 21 and outlet 22 can be arranged at intervals along the axial direction of the rotor 40. The impeller 50 can be located at the connection between the inlet 21 and the outlet 22, that is, the impeller 50 can be located on the side of the inlet 21 closer to the outlet 22, or the impeller 50 can be located on the side of the outlet 22 closer to the inlet 21. The axial direction of the impeller 50 can be the same as the axial direction of the inlet 21 and perpendicular to the axial direction of the outlet 22.

[0059] Please see Figure 6 The ice maker 1000 of this application includes a water tank 200 and an impeller pump 100. The impeller pump 100 is disposed on the water tank 200 and is used to draw water from the water tank 200.

[0060] In this way, by drawing water from the water tank 200 through the impeller pump 100, the ice maker 100 can be provided with the water source required for ice making.

[0061] Specifically, the ice maker 1000 can be a refrigerator or other device with ice-making function. Taking a refrigerator as an example, in one embodiment, the refrigerator is provided with a refrigerator compartment, a vegetable compartment and a freezer compartment from top to bottom. The refrigerator compartment and the vegetable compartment are separated by a partition, and the vegetable compartment and the freezer compartment are separated by a heat-insulating partition. The water tank 200 is located in the refrigerator compartment, and an ice-making tray is provided in the freezer compartment. The impeller pump 100 is connected to a water supply pipe, and the impeller pump 100 delivers water from the water tank 200 to the ice-making tray through the water supply pipe.

[0062] Please see Figure 2 and Figure 6 In some embodiments, the impeller 50 is disposed inside the water tank 200, the second housing 20 passes through the water tank 200 and is fixed to the water tank 200, and the first housing 10 is disposed outside the water tank 200.

[0063] This makes it easy to disassemble and assemble the second housing 20 and the water tank 200 together, so as to clean the components in the water tank 200 and the second housing 20.

[0064] Specifically, the first mounting part 24 can be disposed inside the water tank 200, and the second mounting part 25 can pass through the water tank 200 and be inserted into the first housing 10. The second mounting part 25 can be installed on the side wall of the water tank 200 by welding or other methods. During installation, the water tank 200 and the first housing 10 are mounted on the base, and the engagement of the first housing 10 and the second housing 20 can be achieved by limiting the relative positions of the water tank 200 and the first housing 10 on the base. During disassembly, the first housing 10 and the second housing 20 can be separated by removing the water tank 200 from the base.
