It relates to a desk vacuum cleaner combined with an iron plate eraser to be sucked and collected smoothly.

A conventional vacuum cleaner for a blackboard eraser has a structure in which a blower motor and a filter bag are built into the main body, and a battery for driving the blower motor is inserted, and a blackboard wiping hole is attached to the bottom of the main body.

Such a conventional vacuum cleaner for blackboard eraser holding the main body by hand and wiping the blackboard with a blackboard wiping hole, the chalk powder generated while the chalk letters are wiped is sucked into the main body by the back pressure of the blower motor is collected in the filter bag.

However, such a desk cleaner vacuum cleaner combines only the writing of the blackboard, but did not have a function of cleaning furniture such as a desk and a bookshelf.

An object of the present invention is to provide a blackboard vacuum cleaner combined desk vacuum cleaner that can be attached to the bottom of the vacuum cleaner main body with a suction inlet to be detachably used as a blackboard eraser to clean the desk.

Another object of the present invention is to form a plurality of inclined protrusions and suction grooves on the lower surface of the wiping hole coupled to the bottom of the main body so that the blackboard can be cleaned more cleanly, but the chalk powder can be sucked smoothly into the main body without falling to the outside. A chalkboard eraser combined with a desk vacuum cleaner.

Hereinafter will be described in detail according to an embodiment shown in the accompanying drawings vacuum cleaner desk cleaner vacuum cleaner according to the present invention.

In the drawing, 1 is the main body, and the blower motor 4 in which the impeller 2 is fixed to the shaft 3 is fixedly installed in the middle of the inside thereof, and the battery 5 is built in one side thereof, and the bottom plate 1 ' The suction hole 1a is formed, and the discharge hole 1b is formed in the lower part of the front wall.

The filter bag 6 is fixed to one side of the blower motor 4 so that the air sucked into the suction hole 1a by the suction force of the blower motor 4 passes through the filter bag 6 and then discharges the hole 1b. In the upper front part of the main body 1, the switch control button 7 for turning a blower motor 4 on and off is provided.

As shown in FIG. 2, the blower motor 4 is fixed to the support 1c formed integrally with the main body 1, and the battery 5 is fixed between the support 1c and one side support piece 1d. Although the filter bag 6 is fixed between the support 1c and the other support piece 1d, air sucked into the suction hole 1a by the back pressure of the blower motor 4 passes through the filter bag 6. After the structure is discharged to the discharge hole (1b) can be used any fixed structure.

An elliptical wiping hole 8 is coupled to the bottom of the main body 1.

In the wiping hole 8, the wiping cloth 10 is adhered to the surface of the elastic body 9 having a predetermined width, and a plurality of protrusions 8b are directed toward the front side except for the rear part of the wiping surface 8a. The projections are formed obliquely at an angle of 60 ° to 60 ° and a plurality of projections 8c are formed at the rear portion at an inclined angle at the same inclination angle toward the rear, and these projections 8b and 8c are formed on the outer wall at the inner wall 8 '. It is formed to decrease gradually toward (8 ″).

The inclined protrusions 8b and 8c and the suction grooves 8d therebetween are formed by thermal compression.

In addition, the wiping hole (8) is formed separately for the blackboard using chalk, and the white board using a planetary pen (aka white board: white board), according to the purpose of the wipe cloth 10 is a conventional blackboard eraser and Wiping cloth 10 of the same material as the white plate eraser is used, the wiping cloth 10 can be used in addition to the felt (Felt).

The wiping holes 8 are inserted into and fixed in the wiping hole insertion grooves 1f formed on the bottom surface of the main body 1, and when the wiping white plate is to be used, the wiping holes 8 are used instead of the wiping holes 8 for the blackboard. will be.

In this way, a synthetic resin cover 12 having a suction port 11 is detachably coupled to the bottom of the main body 1 to which the wiping holes 8 are coupled.

The cover 12 is formed such that the intermediate surface 12 'protrudes upwards and recesses downwards, and the projections 12a are elliptical to be inserted into the inner side portions 8' of the wiping holes 8. The engaging jaw 12b in which the outer edge portion 8 ″ of the wiping hole 8 is tightly bent is formed on the outer edge portion of the lid 12 upwardly.

In addition, an elliptical through hole 12c and a coupling piece 12d protrude from the intermediate surface 12 ′ of the cover 12 so as to correspond to one side of the suction hole 1a of the main body 1 ( 1g), the inlet portion 12e of the cover 12 has an inclined opening 11a at one end and a tubular suction inlet of a rectangular section with a through hole 11c formed at the other arc top end 11b. (11) is rotatably condensed in the virtual line state from the solid line state of FIG.

In FIG. 6, 11d and 11f show the fastening protrusions and the fastening grooves formed in the inlet 11 and the cover 12, respectively, and 11e shows the shaft.

Effects of the present invention configured as described above are as follows.

First, in the case of erasing the blackboard, the cover 12 having the suction port 11 is removed in the state of engagement as shown in FIG. 2, and then the wiping port 8 is brought into close contact with the writing plate and the switch operation button 7 is pressed. If you move up, down, left, and right while driving the blower motor 4, the letters on the board are erased by the friction of the wiping surface 8a, and the chalk powder generated at this time together with the air by the back pressure of the blower motor 4 of the battery. It is sucked into the suction hole (1a) through the suction groove (8d), flows into the main body 1 from the suction hole (1a), after which the chalk powder is caught in the filter bag (6) and filtered air is the main body (1) ) It is discharged to the outside through the front discharge hole 1b.

This operation is the same as in the conventional vacuum cleaner for blackboard eraser, but in the case of cleaning the blackboard as described above, a plurality of inclined projections 8b and 8c in the wiping holes 8 are 30 ° to 60 to the front and rear. Because it is formed to be inclined at an angle, when the wiping surface 8a is rubbed with the board up, down, left, and right, it is wiped clean without a portion that is not wiped by the suction groove 8d.

In addition, since the inclined protrusions 8b and 8c are formed to protrude from the inner side to the outer side, the height gradually decreases, so that the inclined protrusions 8b and 8c have good elasticity in close contact with the blackboard. Since it is slightly floated with the blackboard, the polished chalk powder is gathered in each suction groove 8d between the inclined protrusions 8b and 8c without falling naturally to the outside, and is smoothly sucked into the main body 1.

That is, since the outer edge portion 8 ″ of the wiping surface 8a is in close contact with the blackboard, some of the chalk powder will fall freely outside the milia on the outer edge portion 8 ″ of the wiping surface 8a. It can be excluded.

After cleaning the board as described above, by keeping the cover 12 with the suction port 11 attached as shown by the solid line in FIG. 2, the chalk powder buried in the wiping hole 8 does not come out. Will not.

When the present invention is to be used for cleaning a furniture such as a desk or a bookshelf, as shown in the virtual line in FIG. 2, the inlet 11 is opened to face the tip of the inlet 11 to the cleaning part and a switch operation button ( 7) When the blower motor 4 is operated by pressing the dust, first, dirt or the like is sucked into the inlet 11 through the inclined opening 11a, and the through hole 11c of the inlet 11 and the through hole 12c of the lid 12 are pressed. Through the inside of the main body (1) through the same process as when used as a blackboard eraser dust and dirt is caught in the filter bag (6) and then filtered air is discharged to the outside through the discharge hole (11b) .

Thus, the present invention can combine the cover 12 having the suction port 11 to the bottom of the main body 1 to clean furniture such as a desk, and the suction port 11 is tubular, so that the suction area is reduced and concentrated. Eraser furniture on the desk and dust and dirt in the gap of the furniture can be cleaned cleanly, and after cleaning the inlet port 11, the opening of the cover 12 by the circular arc upper end 11b of the suction port 11 ( 12c) is blocked, so chalk powder does not come out, and there is no fear of fouling the surroundings.

The present invention as described above can be detachably coupled to the cover having a suction hole in the main body to clean the furniture such as desks and bookshelves, as well as forming a plurality of inclined protrusions and suction grooves on the wiping holes and wiping surface chalk chalk to the outside Since it can be sucked and removed smoothly without being scattered, the board can be cleaned more cleanly and the surroundings can be kept clean.

As a result, the present invention combines two functions of a blackboard eraser and a desk cleaner and is miniaturized. Therefore, there is no need to purchase two products separately, thereby reducing the cost of purchase and very convenient storage and handling.
