[0023] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1 to 6 As shown, this utility model discloses a water tank integrating a submersible pump, comprising: a water tank 1 and a water pump assembly 2. The water pump assembly 2 includes: an impeller 21, a pump housing 22, a motor winding 23, a winding positioning housing 24, and a drive circuit board 25. The water tank 1 has an impeller mounting portion 11 protruding outward from the water tank 1. A rotating cavity 101 for mounting the impeller 21 is provided within the impeller mounting portion 11 and located inside the water tank 1. The impeller 21 includes: an impeller body 211 rotatably connected to the rotating cavity 101 and blades 212 disposed at one end of the impeller body 211. The pump housing 22 is connected inside the water tank 1. The pump casing 22 is provided with a working chamber 201 for the blades 212 to rotate within it. The pump casing 22 is provided with an inlet 202 and an outlet 203 communicating with the working chamber 201. The impeller body 211 is provided with a magnet 213. The winding positioning shell 24 is connected to the outside of the water tank 1. The motor winding 23 is connected to the winding positioning shell 24, and the impeller mounting part 11 can extend into the motor winding 23 so that the motor winding 23 can interact with the magnet 213 in the rotating chamber 101 to drive the impeller 21 to rotate. The drive circuit board 25 is electrically connected to the motor winding 23. This utility model's water tank features an impeller mounting portion protruding outwards from the tank. The impeller is mounted in a rotating chamber within the mounting portion, and the pump casing is located inside the tank. A motor winding located outside the tank drives the impeller to rotate, allowing water to enter the working chamber through the inlet and exit through the outlet. This design ensures that only the impeller and pump casing are located inside the tank, while the motor windings, winding positioning housing, and drive circuit board are located outside. Therefore, the power cord connected to the drive circuit board does not need to be submerged in water, avoiding the risk of leakage due to damaged insulation. Furthermore, having only the impeller and pump casing inside the tank reduces the space occupied and facilitates cleaning.

[0025] In this embodiment, the impeller mounting part 11 is located at the bottom of the water tank 1. To prevent the water pump assembly from touching the bottom, a support member 3 is provided at the bottom of the water tank 1, and the winding positioning shell 24 is located between the bottom of the water tank 1 and the support member 3. Similarly, the impeller mounting part 11 can also be located on the side of the water tank 1. This is a modification that can be adapted by those skilled in the art according to the actual situation, and will not be described in detail in this application.

[0026] In this embodiment, the support member 3 includes: a support plate 31 and a support edge 32 connected to the outer ring of the support plate 31. The support plate 31 is provided with a positioning hole 301 for positioning the winding positioning shell 24. For the integrity of the whole, a base plate 33 is connected to the lower end of the support edge 32.

[0027] In this embodiment, a rotating shaft 214 is provided inside the rotating cavity 101, and the impeller body 211 is rotatably connected to the rotating shaft 214. The rotating shaft 214 can be made of ceramic material, which is difficult to use.

[0028] The pump casing is detachably connected to the inside of the water tank. To facilitate the installation of the pump casing into the inside of the water tank, the pump casing 22 is provided with a downwardly extending connecting edge 221. The bottom of the water tank 1 is provided with a boss 12 that is sealed and connected to the connecting edge 221.

The inner wall of the connecting edge 221 has a groove 122 that mates with the connecting protrusion 121. The impeller mounting part 11 is connected to the connecting protrusion 121. During assembly, the casing is simply snapped into the boss, and the engagement between the groove 122 and the connecting protrusion 121 prevents the pump casing from falling off.

[0030] In this embodiment, the winding positioning shell 24 is provided with a docking shell 241 in which the impeller mounting part 11 can be embedded. The docking shell 241 is provided with a mounting groove 2410 in which the impeller mounting part 11 can be embedded. The docking shell 241 can extend into the motor winding 23.

[0031] To facilitate knowing the working status of the water pump assembly, an indicator light 251 connected to the drive circuit board 25 is provided on the winding positioning shell 24, and a light-transmitting part 100 corresponding to the indicator light 251 is provided at the bottom of the water tank 1.
