In the description of the embodiments of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0040] The technical solutions of the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0041] Refer to Figure 1 and Figure 2, an integrated external rotor water pump disclosed in an embodiment of the present application, includes: a first housing 10, a rotor 20, a second housing 30, a driving member 40, and a control board 50.

[0042] Among them, the first housing 10 is provided with a first water inlet 11 and a water outlet 12, and is relatively covered with the second housing 30, and fixing holes 101 are provided on the first housing 10 and the second housing 30 for covering and fixing with screw members.

[0043] It is worth mentioning here that the first housing 10 and the second housing 30 are provided as plastic housings. Because plastic housings have the advantages of light weight, corrosion resistance, easy processing, etc., they not only reduce the production cost and maintenance cost of the water pump, but also improve its safety performance.

[0044] See Figure 2 and Figure 3 , the accommodation space formed by the first housing 10 and the second housing 30 is used to accommodate the rotor 20. One end of the rotor 20 is provided with a fan blade member 21, and the other end is provided as a magnetic induction member 22. Among them, a first accommodation groove 31 (located in the accommodation space) is provided on one side of the second housing 30 opposite to the first housing 10 for accommodating the magnetic induction member 22, and a second accommodation groove 32 is provided on the side away from the first housing 10 for accommodating the driving member 40.

[0045] The fan blade member 21 is located inside the first housing 10 (located in the accommodation space), and the fan blade member 21 includes a water inlet end face 211 and a water outlet side face 212. The water inlet end face 211 is docked with the first water inlet 11, which can facilitate the entry of fluid. The water outlet side face 212 is on the same horizontal plane as the water outlet 12, and the water outlet 12 is located in the rotation direction of the water outlet side face 212, which can facilitate the smoother outflow of fluid.

[0046] Among them, in order to be able to adjust the water inlet and outlet directions of the water pump according to actual needs to improve the applicability and flexibility of the water pump, extension pipes 60 are respectively provided at the first water inlet 11 and the water outlet 12. In this way, the extension pipes 60 can also play a role in buffering and stabilizing the water flow, and help reduce vibration and noise during the operation of the water pump.

[0047] In addition, a plurality of convex edges 601 are provided on the circumferential side of the extension pipe 60, which not only enhances the compressive capacity of the extension pipe 60, but also improves the connection stability between the extension pipe 60 and the external pipeline to avoid the slippage of the external pipeline.

[0048] See Figure 2, the control board 50 is connected to one end face of the driving member 40 away from the rotor 20, and the side surface is attached to the second housing 30. In this way, when the control board 50 receives a start signal, it can control the driving member 40 to generate a magnetic field, and the magnetic field interacts with the magnetic sensing member 22, thereby driving the rotor 20 to rotate. The rotor 20 drives the fan blade member 21 to rotate, sucks the fluid from the first water inlet 11, and after being accelerated by the fan blade member 21, discharges it from the water outlet 12 to realize the pumping function of the water pump.

[0049] In addition, in terms of structure, it can be realized that the pump body and the driving part are integrated, that is, an integrated structure design is adopted to improve the use convenience of the water pump, facilitate assembly and maintenance, and at the same time enhance the stability of the overall structure, ensuring the efficient and stable operation of the water pump.

[0050] Specifically, refer to Figure 3 and Figure 4 , a first insertion hole 13 is provided in the first housing 10, and a second insertion hole 33 is provided in the second housing 30. Among them, a limiting member 23 is inserted through the fan blade member 21, which is equivalent to the central axis of the fan blade member 21. One end is inserted into the first insertion hole 13, and the other end is inserted into the second insertion hole 33. In this way, during the operation of the rotor 20, the stability of the fan blade member 21 can be enhanced, and the fan blade member 21 can be prevented from shifting or vibrating during operation.

[0051] Refer to Figure 5 , the fan blade member 21 includes a cover plate 213 and a fan blade bottom plate 214. A plurality of third insertion holes 2132 are provided on the cover plate 213. Around the second insertion hole 33, a plurality of convex members 2141 are provided on the fan blade bottom plate 214. In this way, by inserting the plurality of convex members 2141 into the plurality of third insertion holes 2132, the assembly of the cover plate 213 and the fan blade bottom plate 214 can be realized, and they can rotate together under the driving action of the driving member 40 to drive the fluid to flow.

[0052] It should be noted here that the cover plate 213 is the water inlet end face 211 of the fan blade member 21, which abuts against the first housing 10, and can ensure that the fluid can smoothly enter the fan blade member 21. And a second water inlet 2131 opposite to the first water inlet 11 is provided on the cover plate 213, so that the fluid can enter the inside of the fan blade member 21 from the first water inlet 11.

[0053] Refer to Figure 3 , a plug post 34 is provided at one end of the second housing 30 away from the first housing 10 for the driving member 40 to be sleeved.

[0054] Among them, the second insertion hole 33 is located at one end of the insertion post 34 close to the first housing 10. This design makes the installation of the driving member 40 more stable, and at the same time facilitates the alignment between the driving member 40 and the magnetic sensing member 22, thereby improving the driving efficiency of the magnetic sensing member 22.

[0055] See Figure 2 and Figure 3 , a plurality of coil members 41 are provided on the driving member 40, for example, 12 coil members 41, corresponding to 12 levels, which can increase the power for driving the magnetic sensing member 22, and further increase the water pumping efficiency of the water pump.

[0056] In summary, an integrated outer rotor water pump disclosed in an embodiment of the present application can achieve that when the control board 50 receives a start signal, it controls the driving member 40 to generate a magnetic field, and the magnetic field interacts with the magnetic sensing member 22, thereby driving the rotor 20 to rotate. The rotor 20 drives the fan blade member 21 to rotate, sucks the fluid from the first water inlet 11, and after being accelerated by the fan blade member 21, discharges it from the water outlet 12 to realize the water pumping function of the water pump. Structurally, it realizes the integration of the pump body and the driving part, that is, adopts an integrated structure design, improves the convenience of use of the water pump, is convenient for assembly and maintenance, and at the same time enhances the stability of the overall structure, ensuring the efficient and stable operation of the water pump.
