Abstract
A flow meter includes a lower shell flow meter includes: a lower shell; an upper shell disposed on the lower shell; a running water cavity disposed between the lower shell and the upper shell; and an impeller disposed in the running water cavity. The impeller includes: an installation positioning hole disposed at a bottom portion of the impeller; and a rotating positioning hole disposed at a top portion of the impeller. The flow meter includes an installation positioning shaft extending upward from the lower shell and configured to be inserted into the installation positioning hole; and a rotating positioning shaft extending downward from the upper shell and configured to be inserted into the rotating positioning hole.
Claims20
A flow meter, comprising:
- a lower shell;
- an upper shell disposed on the lower shell;
- a running water cavity disposed between the lower shell and the upper shell;
- an impeller disposed in the running water cavity, the impeller comprising:
- an installation positioning hole disposed at a bottom portion of the impeller;
- and
- a rotating positioning hole disposed at a top portion of the impeller;
- an installation positioning shaft extending upward from the lower shell and configured to be inserted into the installation positioning hole;
- and
- a rotating positioning shaft extending downward from the upper shell and configured to be inserted into the rotating positioning hole.
A flow meter, comprising:
- a lower shell;
- an upper shell comprising:
- a shell body disposed on the lower shell, the shell body comprising a top opening;
- and
- a shell top lid detachably disposed on the top opening;
- a running water cavity disposed between the shell body and the lower shell;
- an impeller disposed in the running water cavity, the impeller comprising:
- an installation positioning hole disposed at a bottom portion of the impeller;
- and
- a rotating positioning hole disposed at a top portion of the impeller and coaxially arranged with the installation positioning hole;
- an installation positioning shaft extending upward from the lower shell and configured to be inserted into the installation positioning hole;
- and
- a rotating positioning shaft extending downward from the shell top lid and configured to be inserted into the rotating positioning hole.
A method for assembling a flow meter, the method comprising:
- forming a running water cavity by connecting a lower shell and an upper shell;
- installing an impeller in the running water cavity by inserting an installation positioning shaft extending upward from the lower shell into an installation positioning hole disposed at a bottom portion of the impeller;
- and
- in response to a non-floating state of the impeller, suspending a rotating positioning shaft extending downward from the upper shell above a rotating positioning hole disposed at a top portion of the impeller,
- wherein a radius of the rotating positioning hole is smaller than a radius of the installation positioning hole, and
- wherein a radius of the rotating positioning shaft is smaller than a radius of the installation positioning shaft.
