0003

However, when characters or the like are erased using the above-mentioned conventional eraser, there is a problem in that the erased debris becomes fine powder and adheres to the surface of the felt or nonwoven fabric, causing clogging. If felt or non-woven fabric becomes clogged, it will no longer absorb eraser debris, and if letters are erased in that state, the eraser powder will scatter into the air, causing harm to the human body, or causing damage to the board. It remains on the writing surface, and even after wiping the writing surface, the writing surface becomes dirty. Further, there is also the problem that the erasing dust adhering to felt or nonwoven fabric cannot be easily removed even by washing, and once the erasing ability is reduced, it cannot be easily recovered.

[0004] Furthermore, when a brush is used to remove dust, the dust scatters and cleaning is difficult. The present invention has been made to solve the above-mentioned problems, and its purpose is to always perform good erasing and cleaning without the risk of dust or dust scattering around or clogging the area.

The suction device 7 is disposed within the housing 1 and includes a motor 8 and an axial fan 9 attached to the motor shaft of the motor 8 within the suction air passage 5 . As the axial fan 9 is rotated by the motor 8, a suction air flow of eraser particles generated during erasing, which will be described later, is generated from the suction port 6 into the suction air passage 5.

The axial fan 9 includes a substrate 10, a plurality of blades 11 provided on the substrate 10 at predetermined intervals,
It consists of a ring-shaped cover plate 12 provided on the blade 11. When the axial fan 9 rotates, a suction air flow is formed passing between the cover plate 12 and the substrate 10 from the center opening of the cover plate 12, and by providing the cover plate 12, this cover plate This prevents a weak air flow from being generated near the outer surface of the suction air passage 5, and prevents dust from adhering to the inner surface of the suction air passage 5.

The recess 13 is formed at the upper part of the front end of the upper case body 2, and a recess 14 is formed approximately in the center thereof, and an exhaust port 15 is transparently provided at the rear of the recess 14. As shown in FIG. 4, a pair of attachment pieces 16 and a lower attachment groove 17 are formed on both sides of the front end of the recess 13. As shown in FIG.

As shown in FIGS. 1 and 3, the accommodating case 18 made of a transparent material is removably attached to the recess 13, and the entire lower surface except the front end is open, and the front end is provided with a flock protruding hole. 19 is formed. The partition wall 20 is integrally formed inside the accommodating part case 18 so as to be located at the front end of the recessed part 14, and the front side of this partition wall 20 serves as the flocked body accommodating part 21, and the rear side serves as the flocked body accommodating part 21. A dust collecting section 22 is located corresponding to the recessed section 14 and the exhaust port 15. A mesh-like filter port 23 consisting of a large number of small holes is formed in the upper part of the storage case 18 so as to correspond to the recess 14, and a filter plate 24 made of a non-woven fabric is removably disposed on the inner surface thereof. There is. Then, the filter port 23 and the filter plate 24
The filtration section 43 is constituted by the above. As shown in Figure 4,
A pair of mounting pieces 25 and an upper mounting groove 26 are formed on both sides of the front end of the housing case 18, and are fitted into the mounting groove 17 and the mounting piece 16, respectively, when the housing case 18 is attached to the housing 1. , position the housing case 18 in the attached state.

The battery accommodating portion 27 is attached to the rear part of the housing 1, and a lid 28 is detachably attached to an opening on the lower surface of the battery accommodating portion 27. The terminal plates 29 are arranged facing each other in the battery accommodating portion 27, and a pair of batteries 30 are placed between the terminal plates 29.
is attached removably. A switch 31 is provided on the outer surface of the housing 1, and when the switch 31 is closed, the motor 8 is rotated.

The flocked body 32 is inserted into the flocked body housing section 2 of the housing section case 18 in a state of protruding forward from the flocked body projection hole 19.
1 so that it can move back and forth. A detailed explanation of the flocked body 32 is as shown in FIGS. 1 to 3.
2 is provided with a square columnar mounting portion 33, and the mounting portion 3
3 is housed in the hair transplant body housing section 21 so as to be movable back and forth. An arcuate cover 34 is integrally formed at the front end of the mounting portion, and support plates 35 are integrally formed on both sides thereof. A cylindrical erasing drum 36 is rotatably supported between both supporting plates 35 while being covered by a cover 34, and an erasing section 37 is formed on the peripheral surface of the drum by flocking using electrostatic flocking. . The erasing section 37 is formed by applying adhesive to the circumferential surface of the erasing drum 36 and pasting a large number of short hairs so as to stand upright in the radial direction. Further, the support plate 35 has an arc-shaped groove 3.
8 is formed, and a protrusion 39 formed on one side of the erasing drum 36 protrudes to the outside through the groove 38.
By operating 9, the erasing drum 36 is rotated. A plurality of through holes 35a are formed in the support plate 35 on one side so as to be located on the circumference around the rotation center of the erasing drum 36, and one or more through holes 35a formed on the side surface of the erasing drum 36 are formed in the support plate 35 on one side. As the erasing drum 36 rotates, projections (not shown) sequentially engage with the through holes 35a, thereby imparting a click state to the erasing drum 36 at a plurality of positions.

As shown in FIGS. 3 and 4, a slope 40 is formed on one side of the front portion of the flocked body accommodating portion 21 of the accommodating portion case 18. As shown in FIGS. The flocked body 3 is arranged so as to correspond to the slope 40.
A wedge member 41 is disposed on one side of the mounting portion 33 of No. 2 so as to be movable back and forth, and a knob 41a formed on one side of the wedge member 41 projects outward through the long hole 42 of the housing case 18. When the wedge member 41 is moved forward by operating the knob 41a, the mounting portion 33 is pinched between the wedge member 41 and the wall portion on the opposite side due to cooperation between the wedge member 41 and the slope 40. When the flocked body 32 is fixed and the wedge member 41 is moved backward, the fixation is released.

Next, the operation of the suction tool constructed as described above will be explained. Now, if you want to use this suction tool to erase characters written on the whiteboard with a special water-based pen, close the switch 31 by pressing while holding the housing 1, and the suction device 7 will open. motor 8
is activated, the axial fan 9 is rotated, and a suction air flow is generated from the suction port 6 into the suction air passage 5. In this state, when the erasing portion 37 formed on the circumferential surface of the erasing drum 36 of the flocked body 32 is erased by sliding it along the whiteboard, the erasing debris that becomes fine powder generated at this time will be erased. It adheres to a large number of hairs in the portion 37. The eraser dust attached to the hair and the eraser dust not attached to the hair are sucked into the suction air passage 5 from the suction port 6 by the above-mentioned suction air flow, and are introduced into the housing case 18 through the exhaust port 15. be done. Then, only the air passes through the filter plate 24 and enters the filter port 23.
Since the eraser is discharged to the outside and falls into the recess 14, the suction force of the suction device 7 does not decrease.
Eraser dust can be sequentially and efficiently stored in the dust collecting section 22.

Therefore, the fine powdered erasure dust generated when the flocked body 32 is used will either adhere to the large number of hairs in the erasing section 37 or be reliably contained within the dust collection section 22.
There is no risk of it being scattered around. By providing the filter plate 24 made of non-woven fabric in the filter section 43, even minute eraser debris can be reliably stored in the dust collection section 22 without escaping into the atmosphere, and there is no risk of harm to the human body. .

Furthermore, if the bristles in the erasing section 37 fall down due to the use of the flocked body 32, the erasing section 37 can be removed by rotating the erasing drum 36 by operating the protrusion 39 of the erasing drum 36. The hair can be removed in another part of the hair, during which time the hair in the fallen part will stand up again and become usable. In other words, by sequentially repositioning the portion of the erasing unit 37 used for erasing, erasing can be performed reliably without reducing the erasing ability.

Furthermore, since the erasing section 37 is formed by flocking, the erasing debris simply adheres to each hair and does not cause clogging, and since the erasing section 37 is flocked, moisture is easily retained at the root part, and the erasing section 37 is formed by flocking. Static electricity will not be generated on the 37 or the board, making it difficult to remove the eraser, or causing excess dust to adhere. Therefore, the erasing debris attached to the erasing section 37 can be easily removed, and the erasing ability is not degraded. Furthermore, flocked hair is resistant to abrasion and can prolong the life of the erasing section 37, is easy to manufacture, can be freely formed into any shape, and can be manufactured at low cost. Also, if the ability of the erasing unit 37 deteriorates,
All that is required is to remove the flocked body 32 and replace it with a new one.

Furthermore, since the housing case 18 is transparent, the extent to which the eraser dust has accumulated can be seen at a glance. and,
When discarding the eraser in the housing case 18, the mounting piece 25 and the mounting groove 26 of the housing case 18 and the housing 1
The accommodating part case 18 may be pulled out forward so that it is disengaged from the mounting groove 17 and the mounting piece 16. Also, inlet 6
Since the suction port 6 can freely appear and retract due to its own weight, even when the whiteboard is horizontal and it is difficult to suck in eraser waste, the suction port 6 lowers due to its own weight and comes into contact with or close to the board. Therefore, even in such a case, suction can be performed reliably without leaving any eraser debris.

[0023]Next, in this suction tool, several flocked bodies are used in exchange for the above-mentioned flocked body 32, so these will be explained. First, the flocked body 44 shown in FIGS. 5 and 6 is used for cleaning dust, etc., and like the flocked body 32, the attachment part 45 is housed in the flocked body housing part 21 of the housing part case 18. It has become so. The passage section 46 is connected to the mounting section 45
An opening 47 is formed at the tip. As shown in FIG. 6, when the flocked body 44 is attached to the housing case 18, the rear end of the passage 46 is connected to the suction port 6, and comes into contact with the housing 1 with the suction port 6 inserted. At the same time, the opening 47 at the tip of the passage portion 46 largely protrudes forward. The dust sucked in through the opening 47 is sent into the suction air passage 5 through the suction port 6.

A stepped portion 48 is provided approximately in the middle of the passage portion 46, and the outer circumferential surface of the passage portion 46 from the front portion of the stepped portion 48 to the opening 47, except for the upper surface, is flocked with flocked portions 49. is formed. The flocked portion 49 is formed by applying adhesive to the surface of the passage portion 46 and pasting a large number of short hairs in an upright state, as in the case of the flocked body 32 described above.

[0025] Then, while holding the housing 1,
When cleaning is performed using the flocked part 49 of the flocked body 44, dust adheres to a large number of bristles of the flocked part 49, and the dust not attached to the bristles is removed from the opening 47 to the suction air passage 5 by the suction air flow. The dust is sucked into the dust collector 22 of the housing case 18 through the exhaust port 15. Therefore, since the dust adheres to the large number of hairs in the flocked part 49 or is reliably contained within the dust collection part 22, there is no risk of it being scattered around. Further, the functions such as restoration of fallen flocking, moisture retention, and abrasion resistance are the same as those of the flocked body 32 described above.

Next, another flocked body 50 will be explained based on FIGS. 7 and 8. As shown in FIGS. 7 and 8, this hair transplant body 5
0 is attached to the tip of the flocked body 44. That is, the attachment part 51 of the flocked body 50 is formed into a square tube shape, and the attachment part 5
1 is fitted into the flocked portion 49 of the flocked body 44. Then, a state in which the attachment portion 51 and the step portion 48 are in contact with each other becomes an attached state, and the flocked body 50 is reliably attached without coming off due to the friction of the flocked hair of the flocked portion 49. A large number of small cylindrical holes 52 are formed at the front opening edge of the mounting portion 51, and each cylindrical hole 5
2 is a brush 53 in which long hairs are implanted in bundles.
is formed. An opening 54 at the tip of the attachment portion 51 is surrounded by the bristles of the brush 53, and the opening 54 communicates with the suction air passage 5 via the passage 46 of the flocked body 44 and the suction port 6.

The flocked body 50 is used for cleaning dust, etc., and is particularly suitable for cleaning keyboards of office automation equipment. That is, when cleaning is performed using the brush 53 of the flocked body 50, dust is sucked into the suction air passage 5 from the opening 54 by the suction air flow, passes through the exhaust port 15, and enters the housing case 18.
The dust is introduced into the dust collection section 22 of. Therefore, the dust is removed from the dust collection section 2.
2, so there is no risk of it scattering around. Furthermore, since the bristles of the brush 53 are relatively long, it is possible to clean small areas.

Furthermore, since the brush 53 is made of flocked bristles, dust only adheres to the bristles and does not cause clogging. Therefore, as in the case of the flocked bodies 32 and 44, dust attached to each bristles of the brush 53 can be easily removed, and the cleaning ability is not degraded.

[0029]

[Second Embodiment] Next, a second embodiment in which the suction tool of the present invention is implemented as an eraser will be described with reference to FIG.

In this eraser, an elastic body such as a sponge, which also has a substantially rectangular parallelepiped shape, is attached to the lower surface of the handle portion 1 having a substantially rectangular parallelepiped shape while being covered with a sheet-like base member 55. The entire outer surface of the base member 55 is flocked to form an erased portion 56.

When using this eraser to erase characters written on the whiteboard with a special pen, hold the handle part 1 in the same manner as a conventional normal board eraser and press the eraser part 56. All you have to do is slide it along the board. When characters, etc. are erased in this manner, the fine powder eraser particles generated at this time adhere to the many bristles of the erasing section 56, as in the first embodiment, and there is no risk of them being scattered around. Further, the functions such as restoration of fallen flocking, moisture retention, and abrasion resistance are the same as in the first embodiment.

As mentioned above, this second embodiment is effective in terms of erasing ability, restorability of fallen flocking, etc. Not only that, but especially compared to traditional board erasers, the eraser debris is only retained between the flocks, so the eraser 5
When washing 6 with water, the eraser waste can be washed away very easily and the water drains easily.
