Description

AIR SUPPLY TYPE MASK [0002]

The present invention relates to an air supply type mask, and more particularly, to an air supply type mask which is used in a form to be worn on a face portion to prevent dust, germs and the like from penetrating through a respiratory apparatus of a human body.

Generally, a filter is a device for separating one substance from another, and means a device used for solid-gas separation, solid-liquid separation, liquid-liquid separation, solid-solid separation and the like.

An air filter means an apparatus for removing impurities from air, and is usually manufactured in the form of a fiber aggregate. In the past, the material of the filter was mainly composed of polymer and fiber, and the filter made of such material was generally capable of collecting and filtering relatively large particles.

In recent years, not only solid dust but also harmful substances such as carbon monoxide, ultrafine dust, and virus have been polluted or harmful to the human body, and harmful substances to be removed tend to be nanoized .

However, the mask having a filter in the form of a fiber aggregate generally used has a problem in that it is not effective due to the space between the face part and the filter, the number of times of use is limited, and nanoized harmful substances can not be properly removed.

In addition, the top product that can remove noxious harmful substances is a dust mask, which is equipped with a purifier filter. However, these respirators are difficult to use for people with weak breathing or breathing difficulties, In addition, there is an inconvenience that a large size canister is required.

BACKGROUND ART [0002] The background art of the present invention is disclosed in Korean Registered Patent No. 10-1201469 (Registered on Aug. 8, 2012, entitled "Mask and Method for Manufacturing the Same").

In this embodiment, it is exemplified that the wearing band 124 is formed in the form of a stretchable fiber material band. The wear band 124 is fixed to the arm of the user by fixing the housing 121 to the arm of the user so that the air supply module 120 can be easily carried by the wearer's arm do.

The battery 125 is installed in the housing space inside the housing 121 and is connected to the operation of the suction pump 122 and the control unit 126, the operation unit 127, the sensor 128 and the display unit 129 Supply the necessary power.

The battery 125 may be replaceably installed in the housing 121 or may be charged using an external power source.

The battery 125 is provided in a compact size that can be installed inside the housing 121 and supplies power necessary for driving the air supply module 120 so that the air supply module 120 can be used for portable use do.

The control unit 126 controls the operation of the suction pump 122 so that the flow rate of the air supplied to the face 110 side is adjusted by the suction pump 122, And transmits the input signal to the controller 126 for controlling the operation of the suction pump 122. [

According to the present embodiment, the operating unit 127 may be provided in the form of a power button, an air supply amount adjusting button, or the like provided outside the housing 121. The user may use the operating unit 127, It is possible to perform operations related to on / off of the module 120 and air supply adjustment.

The sensor 128 is provided to measure the concentration of dust in the air and may include a dust sensor installed outside the housing 121.

The display unit 129 is installed so as to be exposed to the outside of the housing 121 and detects the operating state of the suction pump 122 and the amount of air supplied by the operating unit 127, The information on the concentration of the dust can be outputted through the screen.

Through the display unit 129 thus provided, the user can easily determine whether the suction pump 122 operates normally, the amount of air supplied to the face 110 through the air supply module 120, the concentration of dust in the surrounding air, Can be conveniently checked.

Hereinafter, the action and effect of the air supply type mask according to the present embodiment having the above-described configuration will be described.

1 to 4, the air supply type mask 100 according to the present embodiment can be worn on the user's body by wearing the face portion 110 on the face and the air supply module 120 on the arm . The purified air supplied through the air supply module 120 is supplied to the face portion 110 through the nozzle portion 130. The air is supplied to the face portion 110 through the nozzle portion 130, .

7 and 8, a user who wears the air supply module 120 operates the operating part 127 provided in the air supply module 120 to turn on / off the air supply module 120, An adjustment operation can be performed.

The user can also acquire information on the dust concentration in the air measured through the sensor 128 through the screen of the display unit 129 provided on the front surface of the air supply module 120. Based on the obtained information, (See FIG. 1) and whether the air supply module 120 is operated.

When the user operates the operation unit 127 to operate the air supply module 120, the operation of the suction pump 122 generates a flow of the outside air into the housing 121, And flows into the interior of the housing 121 through the opening 121a.

The air introduced through the inflow port 121a is filtered and deodorized by various kinds of harmful substances including noxious substances by the air filter 123 while passing through the air filter 123, To the suction pump 122 side. The air thus introduced may be supplied to the face portion 110 side through the nozzle portion 130, as shown in FIGS.
