Stator, rotor and end cap, the stator setting in the housing, are formed with pump chamber, the pump chamber between the end cap and shell
In be fixedly installed shaft, the rotor rotation is socketed in shaft, impeller has been wholely set on the rotor, on the end cap
Be extended have with pump chamber perforation water inlet pipe and outlet pipe, rotor from can with stator with driving permanent magnet and packet
The rotor case composition on the outside of permanent magnet is wrapped up in, the permanent magnet is cylinder-shaped and has circular hole, and the rotor case, which has, to be worn
Axis hole at center of circular hole, the rotor case are usually formed by Shooting Technique, and the injection moulding process is general are as follows: passes through first
Penetrating fixing piece in permanent magnet circular hole is plugged and fixed it, and by shell on the outside of injection molding formation on the outside of permanent magnet, later
It is fixed by outside shell of the grafting to rotor, then the mold of corresponding shaft size is plugged at the axle center of circular hole,
And be molded between mold and circular-hole internal-wall and form interior side body, so that interior side body and outer shell body be made to be capable of forming to forever
Shell that magnet is packaged simultaneously makes shell have the axis hole for shaft socket rotation.
But due in injection step twice in order to make that grafting can be stablized between each component, the component being mutually inserted
Between there are certain gap, each injection step can all make between component position generate certain deviation, and then lead to final finished
There is the case where relatively large deviation in the axle center of rotor, and there is the gap for its rotation between rotor and shaft, when rotor rotates
Inevitably generate shake and abrasion.Cause the structure of brushless water pump to become complicated, be unfavorable for producing and processing, when operation is easy to produce
Shake and noise, long-time service be easy to cause parts wear to damage, and service life is shorter.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of simple structure and convenient processing, slow-roll stabilization, makes an uproar
Sound and small, the mute brushless water pump that the service life is longer of abrasion.
To achieve the above object, the utility model provides a kind of mute brushless water pump, includes shell, stator, rotor
And end cap, the stator setting in the housing, are formed with pump chamber, the rotor is rotatably arranged between the end cap and shell
The water inlet pipe and outlet pipe being connected to pump chamber are provided in pump chamber, on end cap, the rotor includes to be molded by Ferrite Material
Made of rotor case and be fixed on ceramic shaft at rotor case axle center by being molded, the rotor case is made by magnetizing
It has magnetism, and rotor one end is arranged in pump chamber integrally formed with impeller, the impeller, is provided on the shell and joins with pump chamber
The other end of logical accommodation groove, the rotor is plugged in accommodation groove, the ceramic shaft both ends be respectively sleeved on the first axle sleeve with
Second axle sleeve, the first axle are set in accommodation groove, and second axis is set on end cap.
By adopting the above technical scheme the advantages of, is: due to the mute brushless water pump of the utility model its rotor case of rotor by
Ferrite Material one-time injection molding, and magnetism is made it have by magnetizing, and simultaneously by ceramic shaft in injection moulding process
It is fixed at the axle center of rotor case, more simple compared with structure for the rotor of the brushless water pump of the prior art, components are less.By
In the number for reducing injection molding in process, keep rotor axis position more accurate, it is not easy to eccentric feelings occur
Condition, and since ceramic shaft injection molding is fixed at the axle center of rotor case, thus rotor case and ceramic shaft can rotate synchronously, two
There is no rotation gap between person, the first axle sleeve and the second axle sleeve being socketed by ceramic shaft both ends reduce ceramic shaft and end
Abrasion between lid and shell, to make to rotate more stable and extend service life.Mute nothing using the above structure
Brush water pump, simple structure and convenient processing, slow-roll stabilization, noise and abrasion are small, and the service life is longer.
The utility model can be further arranged to: the groove that insertion installation is covered for first axle is provided in the accommodation groove,
It is provided with conflict block at the axle center of the water inlet pipe, is circumferentially evenly equipped between the internal perisporium and conflict block of the water inlet pipe several convex
Muscle, the conflict block are cone towards one end of water inlet pipe Way in, and several convex ribs are towards water inlet pipe axis direction
One end and the conflict block other end between formed for the second axle sleeve insertion installation locating slot.
By being further arranged, conflict block stabilization can be supported and fixed at the axle center of water inlet pipe by several convex ribs,
It is formed by locating slot towards between one end and the conflict block other end of water inlet pipe axis direction by several convex ribs, for second
Axle sleeve insertion installation, so that the axle center of rotor and the axle center of water inlet pipe be made to be consistent, improves the emptying effectiveness of brushless water pump,
Convenient for the rotation connection of the ceramic shaft other end.Since conflict block is cone towards one end of water inlet pipe Way in, reduce
The resistance of water flow, water flow can be flowed into pump chamber along the gap between several convex ribs, improve water effect.
The utility model can be further arranged to: the rotor other end is rotatably arranged in accommodation groove, and rotor and appearance
It sets and is formed with rotation gap between slot inner wall, direction has extended to form ring to the rotor outer periphery wall around in accommodation groove opening
Shape protrusion, annular protrusion block between water inlet pipe and the rotation gap.
By being further arranged, annular protrusion can play the role of blocking when water flow enters pump chamber along water inlet pipe straight, to the greatest extent
It is likely to reduced in the rotation gap that water flow pours between rotor and accommodation groove inner wall, avoids rotor because the interference of water flow causes
Unstable problem is rotated, thus more stable when rotating rotor.
The utility model can be further arranged to: it is supported between the impeller and the second axle sleeve and is equipped with the wooden nylon spacer, it is described
The wooden nylon spacer is socketed in ceramic shaft.
By being further arranged, by between rotor and the second axle sleeve support set the wooden nylon spacer, can to avoid rotor with
Abrasion between second axle sleeve, and the rotor other end can be supported and be located on the inner wall of accommodation groove, avoid rotor rotation process
In axial shake, make more reasonable structure, rotate more stable.
The utility model can be further arranged to: the accommodating cavity is by shell towards the end face of end cap side towards the other side
Direction is recessed to be formed, and the depressed section of the shell towards another side direction is formed with pillar, and the stator is socketed on pillar.
By being further arranged, since the depressed section of the shell towards another side direction is formed with pillar and stator socket
On pillar, so that generated magnetic field forms the magnetic field for the part that rotor is located at accommodating cavity when mute brushless water pump operation
Even package, so it is more stable when mute brushless water pump operation.
