Detailed Description

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.

Referring to fig. 1-4, the utility model provides a novel pump assembly, including terminal box 1, rear end cap 2 and motor element 4, terminal box 1 is located on motor element 4's motor casing 5, rear end cap 2 is fixed in motor casing 5's tip, motor casing 5 is equipped with arch 6 and the protruding 7 of L type with terminal box 1 matched with region, terminal box 1's bottom surface with protruding 6 and the protruding 7 fixed connection of L type, terminal box 1's bottom surface is the arc structure, the inside fretwork region that forms of the protruding 7 of L type, stator core's in the motor element 4 coil passes behind this fretwork region and is connected with the drive circuit board in the terminal box 1 to realize the drive to pump assembly.

As an optimized mode of the present invention, the surface of the motor casing 5 is provided with cooling fins which are uniformly distributed in the axial direction.

As a preferred mode of the present invention, the mutually fitting surface of the terminal box 1, the protrusion 6 and the L-shaped protrusion 7 is provided with a gasket (not shown), so that the terminal box 1 and the motor casing 5 can perform a sealing function after being connected.

As a preferred mode of the utility model, motor element 4 keep away from rotor shaft 10 of the pump body on fixed mounting have fan blade 9, the outside of fan blade 9 is equipped with fan casing 8, the fixed mode of fan blade 9 is: a boss is arranged in the fixing hole of the fan blade 9, a groove is arranged on the outer side of the end part of the rotor shaft 10, and when the fixing hole of the fan blade 9 penetrates through the rotor shaft 10, the boss is matched with the groove to achieve the limiting effect of the fan blade 9.
