Laser level meter
A laser level meter, comprising a housing, wherein a laser assembly is mounted on the housing, the lower end portion of the housing is further provided with an end cover, the end cover is recessed towards the interior of the housing to form a cavity, and an air suction port is provided in the cavity. The laser level meter further comprises a suction device arranged in the housing, wherein the suction device comprises a fan, and the fan rotates so as to suck air between the cavity and a mounting surface of the laser level meter from the air suction port.
1. A laser level, comprising:
a housing, a partition plate dividing the housing into an upper part and a lower part, a laser assembly mounted on the partition plate in the upper part of the housing, a lower end of the lower part of the housing being further provided with an end cover, the end cover being sunk toward the inside of the housing to form a cavity, the cavity being provided with a gas suction port;
a protective cover for protecting the laser assembly is further mounted on the housing, the protective cover being provided with a standard hole for emission of a laser beam of the laser assembly;
the laser level further comprising: a suction attachment apparatus arranged in the housing, the suction attachment apparatus comprising a fan in the lower part of the housing, the fan rotating to suck air from between the cavity and a mounting surface of the laser level through the gas suction port, the air sucked by the fan being discharged from the lower part of the housing to the upper part of the housing through a gas discharge port, and from the upper part of the housing to an environment outside the laser level through the standard hole.
2. The laser level as claimed in claim 1 , wherein:
the fan is a centrifugal fan.
3. The laser level as claimed in claim 1 , wherein:
a bottom of the cavity is provided with one or more said gas suction port, the gas suction port being provided in the bottom in such a way as to correspond to a distribution position of a blade of the fan.
4. The laser level as claimed in claim 1 , wherein:
the suction attachment apparatus further comprises a motor, the motor driving the fan to rotate.
5. The laser level as claimed in claim 4 , wherein:
the suction attachment apparatus is mounted on the partition plate by means of a motor seat, and an output shaft of the motor is connected to the fan through a central hole in a hub of the fan;
the cavity is sunk toward the inside of the housing directly opposite the fan.
6. The laser level as claimed in claim 1 , wherein:
the laser level further comprises a spirit level assembly mounted on the housing.
7. The laser level as claimed in claim 6 , wherein:
the spirit level assembly comprises a spirit level for X-axis orientation, a spirit level for Y-axis orientation, and a carrying member for carrying the spirit levels, the two spirit levels being integrally mounted in a mutually perpendicular state on the carrying member, and the carrying member being mounted on the housing.
8. The laser level as claimed in claim 7 , wherein:
a mounting position for mounting the laser assembly is further provided on the carrying member, the laser assembly being integrally mounted at the mounting position.
9. The laser level as claimed in claim 6 , wherein:
a top cover is further mounted at an upper end of the housing, the top cover being provided with an observation hole for observing the spirit level assembly at a position corresponding to the spirit level assembly.
