PUMP AND PUMP ASSEMBLY
Provided is a fluid pump assembly. The pump has a pair of housings magnetically coupled to each other. The first housing contains a drive motor and a magnetic assembly. The second housing contains a magnetic assembly and a blade for imparting movement to a fluid. As the first magnetic assembly is rotated by the drive motor, the magnetic connection to the assembly in the second housing causes the second magnet to rotate, driving the blade.
1 . A pump comprising:
a housing;
a casing disposed in the housing;
a drive motor disposed in the casing;
a magnet disposed in the first housing and operatively associated with the drive motor to rotate when the drive motor is in operation; and
a fan operably associated with the magnet to rotate with the magnet.
2 . The pump of claim 1 , wherein the housing comprises at least one air inlet vent and at least one air outlet vent.
3 . The pump of claim 2 , wherein the air inlet vent and the air outlet vent are in communication with one another along a path extending within the housing and along an exterior surface of the casing.
4 . The pump of claim 1 , further comprising a plate connected between the magnet and the fan.
5 . The pump of claim 1 , wherein the casing comprises an exterior surface having at least one fin that dissipates heat.
6 . The pump of claim 5 , wherein the casing is cylindrical and a plurality of fins are arrayed longitudinally along the exterior surface of the casing.
7 . The pump of claim 1 , wherein the drive motor comprises a rotating shaft and the magnet is connected to the rotating shaft via a threaded fastener.
8 . The pump of claim 1 , wherein the housing comprises a releasably connected bottom cover.
9 . A pump comprising:
a housing comprising at least one air inlet vent and at least one air outlet vent for facilitating airflow through the housing;
a drive motor disposed in the housing;
a magnet disposed in the housing and operatively associated with the drive motor; and
a fan operably connected with the magnet to rotate therewith and draw air through the housing.
10 . The pump of claim 9 , further comprising a plate connected between the fan and the magnet, the plate limiting the affects of the magnetic field created by the rotation of the magnet on the drive motor.
11 . The pump of claim 9 , wherein the drive motor comprises a rotating shaft operably connected to the magnet and the fan.
12 . The pump of claim 11 , wherein the magnet is connected to the rotating shaft through a threaded connection.
13 . The pump of claim 9 , wherein the housing further comprises a bottom cover and a pad attached to the bottom cover.
14 . The pump of claim 9 , wherein the air inlet comprises a rounded outer edge.
15 . The pump of claim 9 , wherein the housing is molded from a polymeric material.
16 . The pump of claim 9 , further comprising a casing surrounding the motor, the casing comprising a fin extending from a surface of the casing towards the housing.
17 . The pump of claim 16 , wherein the fan draws air in through the inlet vents and along the fins and casing.
18 . A pump assembly comprising:
a first housing comprising a top portion and a bottom cover;
a casing disposed in the first housing;
a drive motor disposed in the casing;
a first magnet disposed in the first housing and operatively associated with the drive motor;
a fan connected to the first magnet; and
a second housing containing a second magnet and a blade operatively connected to the second magnet for imparting movement to a fluid,
wherein the first housing and the second housing are capable of being magnetically coupled to one another thought the first and second magnets.
19 . The pump assembly of claim 18 , wherein the first housing comprises at least one air inlet vent and at least one air outlet vent.
20 . The pump assembly of claim 18 , further comprising a plate connected between the first magnet and the fan.
