본고안은 분필가루가 일정간격으로 형성된 브랏쉬 사이를 통하여 흡입되고 집적실에 집적되도록한 진도흡입식 흑판지우개에 관한 것이다.This study relates to an inhalation-type blackboard eraser that allows chalk powder to be sucked through and formed in a chamber at regular intervals.

종래에도 모터에 의하여 분필가루가 흡입되도록한 여러가지의 흡입식 흑판지우개가 있었다.Conventionally, there have been various suction-type blackboard erasers that allow chalk powder to be sucked by a motor.

예를 들어 실용공고81-1443호와 같이 흡입공이 다수 형성된 직포에 걸름포지를 삽착하고 진동판을 연결편에 유착한 탄설편을 끼워설치하고 다수의 격판을 경사방향으로 형성한 원통중앙에 흡입팬을 설치하여 흡입공으로 흡입된 분필가루가 걸름포지에 집적되도록 한것도 있었으나 이러한 지우개는 분필가루가 흡입공을 쉽게 막히게 하므로 흡입력이 저하되고 걸름포지도 분필가루가 쌓일수록 흡입력이 저하되더 흡입이 잘안되면 흡입공 이외의 부분에서 닦이는 분필가루는 흡입공으로 흡수 되지 않고 상당량이 밖으로 떨어져 나가는 문제가 있었고 걸름포지에 쌓인 분필가루를 털기 위하여는 흑판지우개를 모두 분해하여야 할뿐 아니라 걸름포지에 붙어있는 분필가루가 쉽게 떨어지지 않아 분필가루 털기가 어려우며 탄설편을 작동시켜 털때는 분필가루가 많이 날리는 등의 결점이 있는 것이었다.For example, insert a filter cloth into a woven fabric with a large number of suction holes as shown in Practical Publication 81-1443, install a coal tongue piece with the diaphragm attached to the connecting piece, and install a suction fan in the center of the cylinder where a number of diaphragms are formed in an oblique direction There was a case that the chalk powder sucked into the suction hole was accumulated in the filter cloth, but this eraser makes the chalk powder easily block the suction hole. The chalk powder wiped on the part of the paper was not absorbed by the suction hole, and there was a problem of falling off a lot.To remove the chalk powder accumulated on the cloth forge, all the black paper erasers had to be disassembled, and the chalk powder on the cloth was not easily dropped. It's hard to whip chalk, and it's hard Luke was in a lot of shortcomings, such as flying.

본고안은 이러한 제반결점을 시정하기 위하여 브랏쉬틀에 브랏쉬를 일정간격으로 형성하고 브랏쉬틀의 테두리에 밀폐고무가 돌출되도록하여 구멍이 막혀 흡입력이 저하되는 일이 없으면서 분필가루가 흡입되지 않고 밖으로 떨어지는 일이 없도록 하고 집적실에 집적된 분필가루는 개폐판을 열고 간단히 털어낼수 있도록 한것으로서 이를 첨부도면에 따라 상세히 설명하면 다음과 같다.In order to rectify these defects, this paper forms a bracket at a certain interval on the brass frame and seal rubber protrudes at the edge of the brass frame so that the chalk powder is not sucked and falls out without inhaling the hole. Chalk powder accumulated in the accumulation chamber to prevent work and simply to open and close the opening and closing the brush as described in detail according to the accompanying drawings as follows.

지우개(1)의 케이스(2)에 손으로 잡기좋도록 양측이 잘룩하게 들어간 요입부(3)를 형성하고 요입부(3)에 일체로 돌설된 결착봉(4)에 모터식 흡입기(5)의 결착편(6)을 일치시켜 나사못(7)으로 고정하고 흡입기(5)의 배출구(8)에 가루받이(9)의 일측개구부(10)을 끼우고, 가루받이(9)내에 격벽(14)을 형성하여 측부(11)가 막혀있는 집적실(12)과 개구부(20)에 의하여 일측이 개방된 흡입실(13)로 구분하고 격벽(14)의 상부는 집적된 가루가 되돌아나오는 것을 방지하기 위한 절곡단부(15)를 형성하였으며 집적실(12)일측에 배기용 필터부(16)를 형성 가루받이(9)의 타측 개구부(17)는 케이스(2)의 일측에 개폐판(18)에 밀착되게 하되, 개폐판(18)은 좌, 우측에 일체로 형성된 탄성편(20)에 의해 케이스(2)에 탄삽 되게 하였으며 개폐판(18)아래에 형성된 통기망(19)은 요입부(3)를 통하여 필터부(16)와 서로 통하게 하였다.The motor-type inhaler 5 is formed on the binding rod 4 which is formed integrally with the recessed part 3 by forming the recessed part 3 which both sides are cut well so that the case 2 of the eraser 1 may be handled by hand. Coincide with the binding piece 6, and fix it with the screw 7, and insert the one side opening 10 of the dust collector 9 into the outlet 8 of the inhaler 5, and the partition wall 14 in the dust collector 9 ) Is divided into an integrated chamber 12 in which the side 11 is blocked and a suction chamber 13 open at one side by the opening 20, and the upper part of the partition 14 prevents the accumulated powder from coming back. And a bent end 15 for forming the exhaust filter part 16 on one side of the integrated chamber 12. The other opening 17 of the dust collecting plate 9 has an opening and closing plate 18 on one side of the case 2. To be in close contact with, the opening and closing plate 18 is inserted into the case 2 by the elastic piece 20 formed integrally on the left and right, and the ventilation net 19 formed under the opening and closing plate 18 is the recessed portion ( Via 3) And the filter unit 16 were communicated with each other.

흡입공(21)을 향하여 경사면(22)이 형성된 안내판(23)을 흡입기(5)와 가루받이(9)위에 얹어놓고 사각의 브랏쉬틀 (26)에 격판(24)을 일정간격으로 다수 형성하고 격판(24)사이에 부드러운 천으로된 브랏쉬(25)를 끼워 고정하고 브랏쉬틀(26)을 케이스(2)에 삽입하여 고정되게하되 브랏쉬틀(26)과 케이스(2)사이를 고무패킹(27)으로 밀폐시키고 고무패킹(27)은 그 단부가 브랏쉬틀(26)의 테두리에 돌출되게 하여서 된것이다.The guide plate 23 having the inclined surface 22 formed on the suction hole 21 is placed on the inhaler 5 and the dust collecting plate 9, and a plurality of diaphragms 24 are formed on the square bracket 26 at regular intervals. Insert and fix the brush 25 made of a soft cloth between the diaphragm 24 and insert the bracket 26 into the case 2 to be fixed, but the rubber packing between the bracket 26 and the case 2 ( 27) and the rubber packing 27 is made so that the end thereof protrudes to the rim of the bracket 26.

미 설명부호 (28)은 흡입기, (5) 모터, (29)는 흡입기, (5)의 회전팬, (30)은 충전용 플러그, (31)은 모터작동 스위치이다.Reference numeral 28 denotes an inhaler, 5 a motor, 29 an inhaler, a rotating fan of 5, 30 a charging plug, and 31 a motor operated switch.

이와 같이 구성된 본고안은 모터 작동스위치(31)에 의하여 흡입기(5)를 작동시키면 모터(28)가 회전팬(29)을 회전시켜 공기를 흡입하고 배출구(8)로 배출하므로 브랏쉬(25)에 의하여 닦여진 분필가루가 격판(24)사이로 흡수되고 안내판(23)의 흡입공(21)과 흡입기(5)를 통하여 가루받이(9)의 흡입실(13)로 진입하며 흡입실(13)에 진입한 분필가루는 격벽(14)의 절곡단부(15)를 지나 집적실(12)로 들어가고 집적실(12)에서는 공기만 필터부(16)를 빠져나가 요입부(3)와 통기망(19)을 거쳐 지우개(1)외부로 배출되고 분필가루는 집적실(12)로 들어가고 집적실(12)에서는 공기만 필터부(16)를 빠져나가 요입부(3)와 통기망(19)을 거쳐 지우개(1)외부로 배출되고 분필가루는 집적실(12)에 남아 쌓이게되며 집적실(12)의 분필가루는 탄성편(20)을 눌러 개폐탄(18)을 열고 가루받이(9)를 배내어 수시로 제거가 가능한 것이며 고무패킹(27)은 브랏쉬틀(26)의 테두리에 돌출되어 있어 테두리부분에서 브랏쉬(25)에 닦여진 분필가루도 모두 흡입되고 외부로 떨어져 나가지 않는다.In this configuration configured as described above, when the inhaler 5 is operated by the motor operation switch 31, the motor 28 rotates the rotary fan 29 to suck air and discharge it to the discharge port 8, so that the brush 25 Chalk dust wiped by the absorber is absorbed between the diaphragm 24 and enters the suction chamber 13 of the powder collecting plate 9 through the suction hole 21 and the inhaler 5 of the guide plate 23 and enters the suction chamber 13. The entered chalk powder passes through the bent end 15 of the partition 14 and enters the accumulation chamber 12, and in the accumulation chamber 12, only the air exits the filter portion 16 and the indentation portion 3 and the ventilation network 19. The outside of the eraser 1 is discharged through the eraser 1, and the chalk powder enters the accumulation chamber 12, and in the accumulation chamber 12, only the air passes through the filter unit 16 and passes through the indentation unit 3 and the ventilation network 19. The dust is discharged out of the eraser 1 and the chalk powder is accumulated in the accumulation chamber 12. The chalk powder of the accumulation chamber 12 presses the elastic piece 20 to open the open / close coal 18 and discharge the dust collecting container 9. Will often have a removable air rubber packing 27 are projected on the border of Ephrathites switeul 26. There is also wiped all chalk ratswi the probe 25 in the rims of the intake does not go away to the outside.

사용으로 인하여 브랏쉬(25)가 마모되면 브랏쉬틀(26) 전체를 교체시켜 사용할수 있으며 필터부(16)로 여과 되어나온 공기는 통기망(19)으로 배출되기전에 내부에서 회류하면서 모터(28)를 냉각시켜 주므로 모터(28)의 수명을 길게하여 반영구적으로 사용할수 있다.When the brush 25 is worn due to use, the entire brush body 26 may be replaced and the air filtered out by the filter unit 16 may flow back inside the outlet before being discharged to the ventilation network 19. ) Can be used semi-permanently by extending the life of the motor (28).

따라서 본고안은 흡입구멍이 막히는 등의 이유로 흡입력이 저하되는 일이 없고 테두리 부분에서 닦이는 분필가루도 모두 흡입되며 개폐판(18)을 통하여 간단히 가루받이(19)를 끄내 분필가루를 털수 있으므로 분필가루털기가 매우 용이하고 가루받이(9)에는 분필가루가 달라붙지 않으므로 털때 가루가 비산되지 않는등의 효과가 있는 것이다.Therefore, in this paper, the suction power does not deteriorate because the suction hole is clogged, and all the chalk dust wiped off the edge part is sucked. Chalk powder can be removed by simply pulling out the powder tray 19 through the opening and closing plate 18. Whisk is very easy and the powder tray (9) because the chalk powder does not stick to the effect that the powder is not scattered when the hair.
