Description
제 1 도는 본 고안의 사용상태 사시도,1 is a perspective view of the state of use of the present invention,
제 2 도는 본 고안의 재치대 종단면도,2 is a longitudinal section of the mounting table of the present invention,
제 3 도는 본 고안의 지우개 사시도,3 is a perspective view of an eraser of the present invention,
제 4 도는 본 고안의 지우개 일부 절개 단면도.4 is a partial cross-sectional view of the eraser of the present invention.
본 고안은 흑판을 지울때 발생하는 분진을 흡수시켜 분진통에 모으게 하는 흑판 지우개를 재치대에서 들어내면 흡입날개를 착설한 모우터가 자동으로 가동되게 한 흑판 지우개의 재치대에 관한 것이다.The present invention relates to a mounting table of a blackboard eraser that automatically moves a motor equipped with a suction wing when a blackboard eraser, which absorbs dust generated when the blackboard is erased and collects in a dust container, is lifted from the mounting table.
종래의 분진자동 흡인식 지우개는 흑판을 닦은 다음 스위치를 일일히 작동시켜 흡입날개를 착설한 모우터의 가동을 정지시켜야 했기 때문에 사용자의 부주의로 스위치를 끄지 않으면 계속해서 모우터가 가동되어 불필요한 전력소모를 가져오는 결점이 있었다.The conventional dust-automatic suction-type eraser had to stop the operation of the motor equipped with the suction blades by wiping the board and then operating the switch daily. There was a flaw bringing it.
본 고안은 이와같은 결점을 적게하기 위하여 일정 장소에 지우개 재치대를 장설하여 이에 지우개를 재치하였을 경우에는 전원공급이 차단되게 하고 재치대에서 지우개를 들어내게 되면 스위치가 접점되어 전원이 공급되어 모우터를 가동시키므로서 흑판을 닦을 때 발생하는 분진을 흡입할 수 있게 구성한 것으로, 첨부 도면에 의하여 상세히 설명하면 다음과 같다.In order to reduce such drawbacks, the present invention installs an eraser stand in a certain place so that when the eraser is placed, the power supply is cut off, and when the eraser is lifted from the stand, the switch is contacted to supply power. It is configured to suck the dust generated when wiping the blackboard while operating the, described in detail by the accompanying drawings as follows.
동체(1)를 전화기의 송수화기와 같이 형성하여 양단 내부에 장설한 모우터(2)의 회전축에 흡인익편(3)을 착설하고 그 단부에 회전부러쉬(4)(4')를 착설한 공지의 것에 있어서, 재치대(6)의 중앙에 부러쉬 삽지요구(7)(7')를 삽설하면 접점단자(8')가 단락되도록 하여서 된 것이다.The well-known body which formed the trunk | drum 1 like the handset of a telephone, installed the suction blade piece 3 in the rotating shaft of the motor 2 installed inside both ends, and installed the rotary brush 4 and 4 'at the end. In this case, when the brush inserting grooves 7 and 7 'are inserted in the center of the mounting table 6, the contact terminals 8' are shorted.
미설명 부호 5는 집진통, 9는 건전지이다.5 is a dust collector and 9 is a battery.
이상과 같이 된 본 고안의 작용 효과를 설명하면 다음과 같다.Referring to the effects of the present invention made as described above are as follows.
재치대(6)에 형성된 부러쉬 삽지요구(7)(7')에서 동체(1)의 선단에 착설된 부러쉬(4)(4')를 빼내면 접점단자가 탄발스프링에 의하여 올라붙어 모우터(2)가 가동되어 흡인익편(3)과 부러쉬(4)(4')가 회전되어 흑판에 잘 닦아지는 동시에 이때 발생하는 분진이 흡인익편(3)에 의하여 흡인되어 집진통(5)에 집진되며 사용치 않을 경우에는 재치대(6)의 부러쉬 삽지요구(7)(7')에 동체(1)의 양단에 착설된 부러쉬(4)(4')를 삽설하게 되면 상부 요구(7)에 돌설된 출몰단자(8)가 밀려 들어가면서 접점단자(8')가 단락되어 전원을 차단시켜 주므로서 모우터(2)의 회전을 정지케한 것인바, 분진이 날지않고 동체(1)내로 집진되므로 위생적이며 항상 지우개를 일정곳 즉, 재치대(6)의 삽지요구(7)(7')에 삽지시켜 놓아야하기 때문에 항상 질서 정연하게 지우개를 놓을 수 있는 동시에 이와같이 하므로서 불필요한 전력소모를 줄일 수 있는 이점이 있는 것이다.When the brush (4) (4 ') installed at the tip of the fuselage (1) is pulled out from the brush insert (7) (7') formed on the mounting table (6), the contact terminal is lifted up by the bullet spring and the motor ( 2) is activated to suck the suction blade (3) and the brush (4) (4 ') is rotated and wiped well on the blackboard at the same time the dust generated at this time is sucked by the suction blade (3) is collected in the dust collector (5) When not in use, inserting the brushes (4) and (4 ') installed at both ends of the fuselage (1) to the brush insert (7) (7') of the mounting table (6) will protrude on the upper request (7). As the input and output terminal 8 is pushed in, the contact terminal 8 'is short-circuited to cut off the power supply, thereby stopping the rotation of the motor 2. As dust is not collected, the dust is collected into the fuselage 1 without being sanitary. Since the eraser must always be inserted in a certain place, that is, the insertion slot (7) (7 ') of the mounting table 6, the eraser can be placed in an orderly manner at the same time. By doing this, there is an advantage that can reduce unnecessary power consumption.
