Description

{WET TYPE ERASWR FOR BLACKBOARD}

The present invention relates to a wet eraser for a blackboard, and more particularly, to a wet eraser for a blackboard that can supply a predetermined amount of water to a pad member provided on the eraser when the boardboard of the blackboard is erased.

Generally, the chalk is generated by friction between the chalkboard and the chalk powder is adsorbed on the chalkboard. Therefore, not only the chalk powder is generated at the time of writing, but also the chalk powder buried in the chalkboard is decomposed Contamination.

These chalk dusts are sucked into the human body through the respiratory tract and cause mild cough. In severe cases, diseases such as pulmonary disease occur. When the chalk comes into contact with the skin, the chalk absorbs the moisture of the skin or by the chalk powder which is harmful to the human body There is a drawback that the skin becomes very dry and a skin trouble occurs.

In order to solve the above problems, there has been developed a pen-type liquid chalk, a water-erasable chalk, and a wet eraser for erasing such chalk.

However, the conventional wet eraser has an inconvenience that it needs to be cleaned separately at the water level, and the material of the eraser is a sponge that absorbs most of the water, so it is inconvenient to squeeze the water.

An object of the present invention is to provide a wet eraser for a blackboard, which can be conveniently provided when a predetermined amount of water is supplied to a pad member provided in an eraser in a jetting manner to erase a boarder of the board.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are not intended to limit the invention to the precise form disclosed. There will be.

According to an aspect of the present invention, there is provided an eraser comprising: an eraser main body formed to be catchable by a user and having a pad member for erasing a board of a blackboard; A water storage portion formed at one side of the inner side of the eraser main body and configured to store water; A water supply unit connected to the water reservoir through a supply hose and configured to be pressed on the other side of the eraser main body; And a nozzle unit connected to the water supply unit through a discharge hose and configured to spray a predetermined amount of water to the pad member in accordance with a pressing operation of the water supply unit.

The eraser main body is provided with a charging port through which water can be charged into the water reservoir, and the charging port is opened and closed by a cap.

The pad member may have a water guide groove formed on an upper surface thereof to contact the nozzle unit so as to supply water sprayed from the nozzle unit to the entire surface.

According to the present invention, it is possible to provide a wet eraser for a chalkboard capable of spraying water stored in a water storage part to a filter member by a water supply part and a nozzle part, thereby preventing the chalk dust from being generated when the chalkboard is erased The convenience of use can be improved.

1 is a view showing a wet eraser for a blackboard according to the present invention.
FIG. 2 is a view showing the inside of the wet eraser for blackboard shown in FIG. 1. FIG.
FIG. 3 is a view showing a use state of a wet eraser for a blackboard according to the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, the well-known functions or constructions will not be described in order to simplify the gist of the present invention.

FIG. 1 is a view showing a wet eraser for a blackboard according to the present invention, FIG. 2 is a view showing the inside of a wet eraser for a blackboard shown in FIG. 1, and FIG. 3 is a view showing the use state of the wet eraser for a blackboard according to the present invention Fig.

1 and 2, the wet eraser for a blackboard according to the present invention includes an eraser main body 10 formed to be able to be held by a user and provided with a pad member 12 for erasing a boarder of a blackboard, A water storage unit 20 formed at one side of the inner side of the eraser main body 10 and capable of storing water and a water storage unit 20 connected to the eraser main body 10 via a supply hose 32, And a water supply unit 30 connected to the other side through a water supply unit 30 and a discharge hose 42 so as to be pressed by a predetermined amount of water And a nozzle unit 40 that is provided to spray the ink.

The eraser main body 10 is provided to form a main frame of a wet eraser for a blackboard according to the present invention. That is, the eraser main body 10 has a structure in which a user can easily hold the eraserboard when erasing the boarder of the blackboard.

In addition, the eraser main body 10 has a pad member 12 for erasing the boarder of the blackboard at the bottom. The pad member 12 is coupled to the lower portion of the eraser body 10 so as to be in contact with the nozzle unit 40 and includes a water guide groove 13 formed on the upper surface thereof to supply water sprayed from the nozzle unit 40 to the entire surface do. The water jetted from the nozzle unit 40 is guided by the water guide groove 13 so that the entire area of the pad member 12 can be uniformly wetted.

The water storage portion 20 is provided inside the eraser main body 10. That is, the water storage part 20 is formed so as to always store a predetermined amount of water in the eraser main body 10.

The eraser main body 10 is provided with an inlet 14 communicating with the water storage portion 20 on the upper surface so as to store water in the water storage portion 20 and the inlet 14 is opened / .

The water supply part 30 is provided to supply the water in the water storage part 20 to the pad member 12. To this end, the water supply unit 30 is coupled to the other side of the eraser main body 10 so as to be depressed and connected to the water storage unit 20 through the supply hose 32.

The water supply unit 30 serves to supply the water in the water storage unit 20 to the nozzle unit 40 in response to the user's pressing operation.

The nozzle unit 40 is provided at a lower portion of the eraser main body 10 so as to be connected to the water supply unit 30 through a discharge hose 42. The nozzle unit 40 has a structure in which a predetermined amount of water is sprayed to the pad member 12 according to the operation of the water supply unit 30. [

3, when the user presses the water supply unit 30, the water in the water storage unit 20 is supplied to the supply hose 32 and the discharge hose 32, The nozzle member 40 is sprayed onto the pad member 12 after the cap member 42 is exposed.

That is, the nozzle unit 40 supplies water supplied from the water storage unit 20 to the pad member 12 in a spraying manner by a constant pumping pressure generated when the water supply unit 30 is pressed.

Accordingly, the pad member 12 absorbs the water supplied from the water storage unit 20, so that the boardboard of the board can be easily erased.

A water guide groove 13 is formed on the upper surface of the pad member 12 so as to guide the water supplied from the nozzle unit 40 so that the water jetted from the nozzle unit 40 is guided by the pad member 12, So that it can be uniformly supplied to and absorbed by the entire area of the substrate.
