1. A pump comprising:
- a housing having a battery receiving portion configured with a flat wall having electrical terminals arranged thereon for receiving power to the pump; and
a battery having a protruding portion configured with a corresponding flat wall having corresponding electrical terminals arranged thereon, the corresponding electrical terminals being configured to contact respectively both of the electrical terminals on the flat wall of the battery receiving portion to provide power from the battery to the pump when the protruding portion of the battery is inserted into the battery receiving portion of the housing and rotated to an “
ON”
position, and the corresponding electrical terminals also being configured not to contact respectively both of the electrical terminals when the battery is rotated from the “
ON”
position to an “
OFF”
position;
wherein the battery receiving portion has an internal wall configured with at least one axial channel therein; and
the protruding portion has an external wall having at least one protruding portion configured to engage the at least one axial channel for guiding and orienting the battery when inserted into the battery receiving portion into a first rotational position; and
wherein the internal wall of the battery receiving portion is configured with at least one partial circumferential channel; and
the at least one protruding portion is configured to engage the at least one partial circumferential channel for rotating the battery from the first position when the protruding portion of the battery is inserted into the battery receiving portion of the housing into either a second rotational position, including the “
ON”
position where the pump is turned “
ON”
, or to a third rotational position, including the “
OFF”
position where the pump is turned “
OFF”
.

position;wherein the battery receiving portion has an internal wall configured with at least one axial channel therein; and
the protruding portion has an external wall having at least one protruding portion configured to engage the at least one axial channel for guiding and orienting the battery when inserted into the battery receiving portion into a first rotational position; andwherein the internal wall of the battery receiving portion is configured with at least one partial circumferential channel, the at least one partial circumferential channel has a flexible locking device having a first face and a second face that is configured on a flexible hinge portion;
the first face is configured on an angle so as to respond to the at least one protruding portion and flex the flexible locking device downwardly into an opening or slot and below a surface of the at least one partial circumferential channel so as to allow the at least one protruding portion to slide or pass by when the battery is rotated in one direction in the battery receiving portion;
the flexible locking device is configured to flex back upwardly above the surface of the at least one partial circumferential channel once the at least one protruding portion slides or passes by the first face; and
the second face is configured to extend into the partial circumferential channel above the channel surface so as to prevent the at least one protruding portion from passing or sliding by when the battery is rotated in an opposite direction in the battery receiving portion so as to lock the battery in the battery receiving portion so it cannot be removed. - View Dependent Claims (9)
