Description

Dust Mask {ANTI DUST MASK}

The present invention relates to a dust mask, and more particularly, it can be quickly exhausted by inhaling the external air to be forcibly discharged by the discharge means, and also the discharge means is driven by a solar cell to minimize the maintenance cost It is about a dust mask that can be made.

In general, dust masks come into the respiratory tract with a large amount of harmful dust generated during work by workers in various industrial sites such as paper mills, textile mills, quarries, or metal processing plants such as chemical plants and welding plating. Used to prevent losing.

As shown in FIG. 1, the dust mask A 'includes a mask body 1' having a hemispherical curved structure to cover a mouth and a nose portion of the worker, and the mask body 1 'with the mask body 1'. It is largely composed of a band 2 'which is a means for fixing to the face.

That is, when the worker inhales the air while wearing the dust mask A ', the outside air is introduced through the intake port 3' formed at the front of the mask body 1 ', and the introduced air passes through the filter to the foreign matter. After entering the filtered state into the interior space, it is transmitted to the worker's respiratory tract.

However, the dust mask has a problem in that the smell of the person's mouth enters his nose when the breath is discharged, and the temperature inside the mask increases due to the temperature of the body and the person when the body is discharged. .

In addition, as the temperature of the mask increases, people wearing glasses have a problem that the moisture rises through the gap of the nose and the glasses get wet.

The present invention has been made to solve the above problems of the prior art, equipped with a discharge means to quickly discharge the air discharged after breathing to the outside to prevent odor and temperature rise to provide a comfort dust mask The purpose is to provide.

In addition, there is another object to provide a dust mask that is semi-permanent and low maintenance cost by providing the power of the discharge means through a solar cell.

The above object of the present invention has a hemispherical shape and is fixed in close contact with the operator's face with a band connected to both sides, the mounting hole is formed in the front, the body made of breathable material; A case attached to the outside of the main body; A mounting hole inserted into the case and coupled to a mounting hole of the main body and having an air passage formed therein, and an opening and closing membrane formed in the air passage; It can be achieved by a dust mask comprising an exhaust fan and a motor mounted to the mounting port and a solar cell mounted to the case, the exhaust means for forcibly exhausting.

The case is characterized in that the switch for controlling the on / off of the exhaust fan.

Inside the case is characterized in that the storage battery is further installed to store the electricity produced by the solar cell.

The main body and the case is detachably coupled, characterized in that to replace the main body.

According to the present invention, by sucking the outside air to be forced to discharge by the discharge means can be quickly exhausted, and also the discharge means is driven by a solar cell has the effect of minimizing the maintenance cost.

1 is a cross-sectional view showing a prior art,
2 is a cross-sectional view showing a dust mask according to the present invention;
Figure 3 is a cross-sectional view showing another embodiment of a dust mask according to the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a cross-sectional view showing a dust mask according to the present invention, Figure 3 is a cross-sectional view showing another embodiment of the dust mask according to the present invention.

As shown in FIG. 1, the dust mask A according to the present invention has a hemispherical shape and is fixed to the operator's face with bands connected to both sides thereof, and a mounting hole 13 is formed at the front, and a breathable material. Main body 1; A case (2) attached to the outside of the main body (1); The mounting hole 3 is inserted into the case 2 and coupled to the mounting hole 13 of the main body 1, and an air passage 10 is formed, and the opening and closing membrane 12 is formed in the air passage 10. ; The exhaust fan 43 mounted on the mounting hole 3 and the motor 44 and the solar cell 6 mounted on the case 2 are configured to include a discharge means 4 for forced exhaust.

The case 2 is equipped with a switch 5 for controlling the on / off of the exhaust fan 43.

The main body 1 is mounted to correspond to the user's face and mouth, and is generally hemispherical in shape, as is known, and its material is particularly inhaled through the entire area of the main body during inhalation by using a breathable nonwoven fabric.

Therefore, the conventional main body is a non-breathable material, so the amount of suction is somewhat insufficient, but the present invention can be intake through the entire area of the main body 1 so that a sufficient amount of suction can be provided.

The case 2 has a plurality of through-holes 20 are formed on the front and the bottom to enable the movement of the discharged air is attached to the front of the main body 1, so as to be detachable if possible to contaminate the main body 1 later However, if a performance decrease occurs, only the body 1 can be replaced.

As an example, in the detachment method of the case 2, it is preferable to apply a Velcro fastener.

The mounting hole 3 is attached to correspond to the mounting hole 13 of the main body 1, the air passage 10 is formed therein, the elastic opening and closing membrane 12 is coupled to the air passage 10 In the case of intake, the opening / closing membrane 12 is closed backward to close the air passage 10 while closing the air passage 10, while the exhaust passage is opened forward while opening the air passage 10.

Discharge means (4) is composed of a housing (42) mounted to the mounting opening (3), the exhaust fan 43 and the motor 44 coupled to the housing 42, mounted on the case (2) It comprises a solar cell 6 for supplying to the motor 44.

On the other hand, as shown in Figure 3, the inside of the case 2 is further installed a storage battery 7 for storing the electricity produced in the solar cell (6).

Thus, by the addition of the battery 7 it is possible to drive the discharge means 4 by being supplied with electricity for a predetermined time even in a day or a bad daylight.

Referring to the operation of the present invention configured as described above are as follows.

The mounting hole 3 is coupled to the front surface of the main body 1, and the housing 42 having the exhaust fan 43 and the motor 44 coupled to the front of the mounting hole 3 is attached.

After the case 2 is coupled to the front of the main body 1, the solar cell 6 is mounted on the outer upper portion thereof, and then the wires are connected to the motor 44 to allow electricity to flow.

And a switch 5 for controlling the on / off of the motor 44 is mounted on one side, preferably the lower side of the case (2).

Thereafter, when the switch 5 is turned on, the motor 44 is driven by electricity supplied from the solar cell 6, and the exhaust fan 43 is rotated in association with the switch.

The rotation direction of the exhaust fan 43 should be a direction for discharging air in the main body 1 to the outside.

Therefore, when the wearer breathes, the air is inhaled through the entire area of the breathable body 1, and the breathing discharged is quickly discharged to the outside by passing through the through hole 20 of the case 2 by the exhaust fan 43. .

As this exhaustion is accelerated, it is possible to exclude the odor and high temperature discharged, thereby obtaining comfort, and preventing the bleeding on the glasses.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, It is obvious that the claims fall within the scope of the claims.
