Individual partially circumferentially passage；With
Battery, this battery is with having the projection of corresponding electric terminal, and this correspondence electric terminal is configured to contact battery and connects
Receive the electric terminal in part, in order to and rotate in one direction in the projection of battery inserts the battery receiving portion of housing
Provide power to the cascaded structure of integral pump during to "ON" position, and corresponding electric terminal is also configured in order to not revolve when battery
The electric terminal of battery receiving portion is not contacted when forwarding "ON" position to,
Described projection has outer wall, and this outer wall has the projection that at least one is other, this at least one other convex
Go out part to be configured to engage at least one axial passage, in order to guide when battery inserts battery receiving portion and orient electricity
Pond is to the first position of rotation, and at least one other projection is configured to bonding part circumferential passageway so that at battery
Projection insert housing battery receiving portion in time by battery from the first position of rotation rotate to the second position of rotation or
3rd position of rotation, the second position of rotation includes "ON" position, wherein the cascaded structure "ON" of integral pump, the 3rd position of rotation bag
Include off-position, wherein the cascaded structure "Off" of integral pump；
At least one partially circumferentially passage there is flexible locking device, this flexible locking device has first and second, should
Flexible locking device constructs on flexible hinge portion；
First along an angle structure, in order to responds with at least one other projection described, and is filled by flexible locking
Put and bend downward in an opening or slit and be positioned under the surface of axial passage, thus when battery is in battery receiving portion
At least one other projection is allowed to slip over or pass through when rotating in one direction；
Flexible locking device is configured to slip over once at least one other projection or be bent upwards by first
Return on channel surface；With
Second surface construction is for extending to partially circumferentially in passage on channel surface, thus when battery is in battery receiving portion
Prevent at least one other projection from passing through or slipping over when rotating in mutually opposite directions, thus battery lock is received at battery
In part, battery is made not to be removed.
14. practical pumps according to claim 13, wherein, housing has a switch, and this switch structure becomes responding to switch
Activate and flexible locking device be moved down in opening or slit and be positioned under channel surface, in order to when battery is at electricity
Allow at least one other projection to pass through when pond receiving portion rotates along described rightabout, thus battery can move
Move the first position of rotation, and remove from battery receiving portion.
