The air intake conduit 230 has an air intake 232 for sucking air in the lower rear portion of the LED module receiving groove 231 , and an air intake for introducing the sucked air into the center of the air intake 232 . A ball 233 is formed. The air intake pipe 230 is formed to extend from the air suction hole 233, the air intake pipe (235).

In one embodiment, the air intake 232 is formed along the front surface of the cleaning pad part 220 and decreases in depth and width toward both ends based on the long air intake hole 233 disposed in the center. It is possible to increase the suction efficiency by allowing the formed and sucked air to converge into the air suction hole 233 . The air intake 232 may be spaced apart from the cleaning floor by the protruding height of the drum wheel assembly 225 of the cleaning pad 220 to suck foreign substances and dust into the floor surface. Air sucked along the air intake port 232 is introduced into the air intake pipe part 230 through the air intake hole 233 , and the air intake is disposed at the lower end of the upper housing 211 of the nozzle body part 210 .

Here, the air intake pipe 230 may be exposed to the outside through the “open” of the open cover 213 . Accordingly, dust or foreign substances accumulated on the air intake pipe 235 can be easily removed, thereby preventing clogging of the pipe and maintaining the suction power even when the cleaner is used for a long time.

In the case of a wet mop cleaner, dust or foreign substances do not pass properly along the air passing through the air suction conduit 230 due to the moisture of the mop detached from the cleaning pad 220, and the inner wall of the air suction conduit 230 As they accumulate, the air intake may be reduced. In this case, in the case of the cleaner head device 100 according to an embodiment, the inner wall of the air intake pipe 230 is opened to the outside by separating the opening cover 213 of the nozzle body 210 to easily clean and increase the air suction power. can be restored

In the cleaning pad 220 , the drum wheel assembly 225 is disposed in the center of the front lower part, so that the air suction port 232 is spaced apart from the cleaning floor by a predetermined height to perform air suction, thereby increasing suction efficiency. The drum wheel assembly 225 accommodates the drum wheel 320 in the drum wheel accommodating hole 311 of the front lower protrusion 310 protruding from the front lower portion to assist the movement of the cleaner through the rotation of the drum wheel 320 . can Here, the drum wheel assembly 225 may be formed to protrude to a predetermined height in consideration of the suction efficiency of the air intake port 232 . The drum wheel assembly 225 allows the front of the nozzle body 210 to maintain a constant height from the floor even if the mops are reduced in height due to long-term use. Accordingly, when the cleaner is used, the lower end of the nozzle body 210 is inclined downward toward the rear with respect to the front, so that even if the height of the mops is reduced, at least the rear of the mops are always in close contact with the floor to increase cleaning efficiency and mop use efficiency. can

The cleaner head device
a nozzle body including an upper housing;
Circular mop attachment members disposed at the lower end of the nozzle body, a driver disposed on the upper portion to drive the circular mop attachment members, and a worm mechanism connected to both sides of the actuator to rotate the circular mop attachment members A cleaning pad comprising a; and
LED (Light Emitting Diode) module accommodating groove formed along the front surface of the circular mop attachment members, which is disposed on the lower end of the nozzle body and the upper end of the cleaning pad part, is formed in the lower rear of the LED module accommodating groove to suck air An air intake pipe comprising an air suction port, an air suction hole formed in the center of the air intake port, and an air intake pipe formed to suck the sucked air from the air suction hole along the lower end of the upper housing, integrally injection-molded; including,
The air intake pipe
Extending the air intake hole and arranging the air intake pipe in a streamline shape along the upper part of the actuator, forming a bent pipe in which the end of the air intake pipe is bent in a U shape to drop the sucked air, Form an air discharge nozzle hole in the bent pipe and connect it to the nozzle pipe,
The LED module receiving groove is
It is designed to cover the air intake hole in the rear inner center, and is composed of protrusions that are formed to protrude forward by a predetermined length from both sides of the rear inner side and include a shaking preventing member that prevents the front and rear shaking of the inserted LED module. Features a vacuum cleaner.
