PURPOSE: A dust suction head is provided to prevent outflow of collected dust because outside air is smoothly flowed inside by using an air inlet hole and a blocking member while in vacuum suction. CONSTITUTION: A dust suction head(1) comprises a head body(10) and a suction pipe connection unit(20). The head body is formed into a shape of a transparent bowl of which a lower side is opened. A nozzle of an air spraying device is inserted in a nozzle insertion hole(14) of the head body. Dust scattered by the air which is sprayed through the nozzle is collected inside the head body. One end of the suction pipe connection unit is connected to a suction pipe of a dust suction device and the other end of the suction pipe connection unit is connected to a suction pipe connecting hole on the peripheral surface. |
