Description
Technical field
The utility model belongs to motor manufacturing technology field, relates to a kind of electric water pump rotor magnet.
Background technique
Rotor magnet in electric water pump is connected with impeller, and some employing axle sleeves connects, and has to adopt directly to connect, and rotor magnet and impeller is formed to be connected reliably be to make impeller wheel portion and rotor portion rotate simultaneously, avoids when rotation delayed to some extent.And in currently used Placement, some Placement is unreliable, thus unreliable for wheel rotation, can phenomenons such as coming off be caused; The Placement separately having the impeller of some electric water pumps and rotor magnet to adopt, is not easy to the continuous seepage of the automatic assembly line of electric water pump impeller.In addition, its epitrochanterian blade of existing water pump is generally straight line shape, the flow of the water that the waterleaf of this kind of linear structure produces can not meet higher requirement, in order to enough flows can be reached, general is all adopt high-power rotor to realize, the increasing of electric energy loss can be caused like this, thus add cost.
Chinese utility model patent (application number is 201120062654.9) discloses a kind of ferrite magnet rotor for water pump, comprise rotor body, axis hole is provided with at described rotor body center, described rotor body overlaps and has permanent magnet, described rotor body one end is provided with a junction, described joint is connected with an impeller base, described impeller base is evenly equipped with multiple arc shaped blade.This ferrite magnet rotor for water pump solves part energy consumption problem, but the connection of ferrite magnet rotor and impeller is still reliable not.
Therefore, need to develop a kind of electric water pump rotor magnet, make this Magnmet rotor and impeller form reliable connection.
Model utility content
The technical problems to be solved in the utility model is, provides that a kind of structure is simple, reasonable in design, the safe and reliable electric water pump rotor magnet that can not come off that is connected with impeller of rotor magnet when using.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: this electric water pump rotor magnet comprises rotor magnet and impeller, described rotor magnet is provided with at least one first groove, and described in the upper end edge of described first groove, the sidewall of rotor magnet is provided with bump; Described impeller comprises impeller base, the lower end of described impeller base runs vertically down and is provided with impeller handle, described impeller handle is provided with the second groove in the relevant position at bump place, and described impeller handle is matched by the second groove and the first groove and lug boss and forms compact siro spinning technology with rotor magnet.
In technique scheme, by being arranged on rotor magnet, the first groove and lug boss are set, second groove is set in the corresponding position of impeller handle simultaneously, being matched by the second groove and the first groove and lug boss makes impeller handle and rotor magnet form compact siro spinning technology again, can prevent impeller from moving radially, avoiding coming off, realize the run-in synchronism of impeller and rotor magnet, avoiding occurring retardation phenomenon when rotating.
Further improvement is, the upper end of described impeller base upwards extends the impeller blade of the fan arc being provided with several maximum areas.The impeller blade of fan arc effectively can increase pump capacity, reduces the energy consumption of water pump.
Further improvement is, the top of described impeller blade upwards extends and is provided with raised ribs.Raised ribs is set and can reduces turbulent flow, thus increase pump capacity.
Further improvement is, the cross section that described raised ribs is is triangle.
As preferred version of the present utility model, the quantity of described impeller blade 4.
As preferred version of the present utility model, the quantity of described first groove is 4; Accordingly, the quantity of described lug boss is 4, and the quantity of described second groove is 4.4 the first grooves and lug boss and the second groove can prevent impeller from moving radially best.
As preferred version of the present utility model, the center of described impeller base is provided with a motor shaft through hole.
Further improvement is, described impeller be integrated arrange shaping, described rotor magnet be integrated arrange shaping.
The utility model beneficial effect is compared with prior art: the utility model is reasonable in design, structure is simple, good manufacturability, what during use, rotor magnet was connected with impeller safe and reliablely can not come off, effectively can increase pump capacity, reduce energy consumption, be particularly suitable for the continuous seepage of the automatic assembly line of electric water pump impeller assembly.
