Powered Air Purifying Respirator {

[0001] The present invention relates to a breathing-linked electric type respiratory protection device, and more particularly, to a breathing-linked electric breathing apparatus having a breathing interlocking type electric breathing apparatus, It can be lightweight and compact to maximize wearer's comfort and limit the range of activity. It can also be worn by adjusting the ratchet knob with one hand through the neckband. The present invention relates to a respiratory protection type respiratory protection type breathable interlocking type respiratory protection type respiratory protection type respiratory protection type respiratory protection type respiratory protection type.

Welding is a metal process that joins two or more solid metals together. High energy sources such as high-pressure electricity, oxygen, acetylene, argon, etc. are used for welding. The hazards and hazards caused by welding are caused by welding fumes (metal components contained in fumes), harmful rays, noise, and high temperature environment that arise in welding work.

Especially, in case of arc welding in a narrow and closed workshop, welding workers suffer health damage due to welding fumes and nitrogen oxides generated in the welding process. In recent years, as well as pneumoconiosis caused by welding fumes Manganese poisoning accidents have occurred due to the use of welding electrodes, and measures for the health problems of welding workers have been demanded.

Welding fume is a fine particle generated by cooling of material evaporated by heat during welding. It is generated by diffusing molten metal vapor around by arc heat generated by high temperature. The amount of fume generated and arc current The relationship shows that the larger the current, the voltage, and the diameter of the electrode, the greater the amount of generated gas.

On the other hand, harmful gas generated by welding has not been attracted attention as much as welding fume, and the perception of harmfulness is lower than welding fume. However, there are various kinds of harmful gas such as ozone, nitrogen oxides, carbon monoxide, carbon dioxide, hydrogen fluoride, phosgene, phosphine, and products produced by pyrolysis of paint and film components.

Conventionally, it protects eyes from harmful rays generated during welding and cutting work of arc and gas, and automatically protects workers from the risk of burns due to heat generated by heat during the welding, such as heat on the face and neck, In recent years, there has been a growing awareness of the importance of respiratory protection in hazardous workplaces as well as the use of light-shielding means. Recently, there has been no systematic restriction on the importance of respiratory protective equipment .

In the case of conventional automatic shading welding surfaces, it is clear that welding fumes, harmful dusts, harmful odors and odors generated during the work can not be blocked. Therefore, in order to prevent users from drinking harmful fumes generated during welding work, A respirator (welding surface air feeder) has been developed and supplied. However, the conventional electric-type respirators have a very high unit price and a very high market negative factor in terms of wear and activity.

A typical electric breathing apparatus consists of an automatic welding face, a motor, a battery, a hose, a blower fan, and a filter, and is usually sold at a price of about 100 to 1.5 million won. This is because the existing electric-type respirator is connected to the automatic welding surface through the hose and continuously supplies a certain amount of purified air to the automatic welding surface, so that the motor, battery, filter and the like must be used to be.

The electric respirator uses a method of sucking in outside air contaminated with self-power in a place where welding fumes, harmful dust, harmful smell, odorous workplace and respiratory infectious diseases occur, and filtering the filtered air to the operator. However, in the conventional electric type respirator, the filter body is worn on the back of the waist and the long hose is connected to the automatic welding face, so that it is inconvenient to wear because of its large volume and weight, .

In addition, since the conventional electric type respirator has a structure in which a constant flow rate of air is continuously supplied to the inside, it is very inconvenient for a long period of time of use, which causes inconvenience to the wearer and inconvenience of wearing And the need for a lightweight device is very high.

1 to 5, a respiratory-linked electric breathing apparatus 10 according to an embodiment of the present invention includes a mask unit 100, a generator unit 200, a neck support unit 300, a connect unit 400 And a back support part 500.

The mask part 100 is a part worn on the face part so as to surround the user's mouth or nostril. The portion directly covering the face portion is preferably formed of a soft material such as silicone rubber. Basically, it is a means for protecting the user's respiratory apparatus against welding fumes, harmful dust, harmful odors and odors generated during the operation. To this end, an exhaust hole 110 is formed on one side so that the exhaust air discharged by the user is discharged to the outside by pressure, so that the inflow of the outside air can be blocked and only the user can breathe out.

The generator unit 200 filters external air and filters the air to the mask unit 100. Accordingly, the generator unit 200 includes a HEPA filter 210, a motor, a fan, a pressure sensor, a power switch 230, and the like. It is possible to filter the air introduced from the outside by providing a HEPA filter (210) which is formed in the outward direction and can be replaced according to the necessary dust collecting efficiency.

In addition, the generator unit 200 in the breathing-linked type electrosurgical breathing apparatus 10 according to the embodiment of the present invention senses the intake air of the user through the pressure sensor, thereby newly introducing external air through the fan, It is the most important feature to operate in conjunction with. When the user drinks fresh air inside the device, the internal pressure drops. When the pressure sensor senses this, fresh air is introduced into the device.

The pressure sensor can be either electronic or mechanical, and the most suitable method for the actual circuit configuration can be used. It is also possible to vary the speed of the internal fan according to the change in the user's respiratory amount detected by the pressure sensor.

In the conventional electric type respiratory protection device, since a constant flow rate of air is continuously supplied to the respiratory side of the user, the eyes may be scooped when used for a long period of time, which can give a great inconvenience and pain to the user. (10) according to the present invention can solve this problem because it operates in a non-continuous manner in conjunction with the user's breathing.

In general, when using a filter that has a dust collecting efficiency of 94% or more in an environment requiring a mask, the user usually feels a little inconvenient to breathe. In particular, at least 99.5% of the filter must be used in the welding work environment. In this case, the adoption of the breathing interlocking type transmission system as in the embodiment of the present invention enables the inflow of external air, filtering and natural circulation of intake air.

The operation of the generator unit 200 is preferably such that a battery 220 such as a lithium polymer that can be charged at one side of the generator 220 is installed to receive power. In order to use in various working environments such as actual welding work, it is important to apply a power capacity corresponding to at least 4 hours of actual use time. In order to easily recognize the remaining amount of the battery 220, It is preferable that the battery 220 remaining amount display means is formed on one side.

A power switch 230 is separately provided on one side of the generator unit 200 so that the user can forcibly terminate the electrical operation of the entire apparatus irrespective of the respiration state when the user presses the power switch 230. Also, the control of the airflow can be performed through the power switch 230, and the power switch 230 may be set to perform various functions.

The connecting unit 400 functions to connect the mask unit 100 and the generator unit 200 to each other to provide a passage through which the filtered air flows toward the mask unit 100. Here, the term " both sides " means that the user is provided so as to pass both sides of the face when the mask part 100 is worn on the mouth or nostril side.

The connecting unit 400 includes a first connecting pipe 410 having a predetermined strength and coupled to the mask unit 100 and extending to the other side of the connecting unit 400. The connecting unit 410 includes a first connecting pipe 410 having one side coupled to the generator unit 200, A bracket 430 fixed to the other side of the first and second connection pipes 410 and 420 and detachably coupled to the first and second connection pipes 410 and 420, .

The first connection pipe 410 and the second connection pipe 420 are detachably coupled through the bracket 430 so that the mask unit 100 can be separated from the generator unit 200, The first and second connection pipes 410 and 420 are connected to each other through the bracket 430 after the generator unit 200 is mounted on the neck of the user after the user 100 is worn. (100) are separately separated to facilitate cleaning of the foreign matters attached to the inside by the user's breathing.

A corrugated tube 440 made of a rubber elastic material is formed to have a predetermined length at one end of the second connection pipe 420, that is, at the end of the second connection pipe 420 coupled to the generator 200, When the head 100 is moved up and down with the head 100 being worn, only the corrugated tube 440 made of an elastic material is moved independently of the generator portion 200 to move.

It is also possible to further provide a band ring 431 on one side of the upper portion of the bracket 430 so that the band ring 431 on both sides is combined with an additional binding means such as a string to induce more firm fixation to the back of the neck.

The neck support part 300 is attached to both sides of the connecting part 400 and is formed to surround and support the user's neck. The neck support portion 300 includes a neck band 310, a connection body 320, and a support wing 330.

The neckband 310 is extended from both sides of the connecting part 400 and is engaged at the back of the user's neck when the user wears the breathing-linked electric breathing apparatus 10 of the present invention. This neckband 310 engages behind the user ' s neck to allow the device to be securely fastened to the head.

The neckband 310 is hinged around the rotation axis 311 so that the neckband 310 can be rotated from a portion where the neckband 310 is connected to the connecting portion 400, Even if the user rotates the head, the fluidity can be given correspondingly.

The coupling body 320 is formed with a coupling groove 321 through which the neckband 310 is inserted from both sides and coupled with a neckband 310 inserted into the coupling groove 321 in a ratchet structure And a control knob 322 that can adjust the fastening state of the neckband 310. [

As described above, when the user wears the respiratory-protection type respiratory protection device 10 of the present invention, the neckband 310 is bound at the back of the user's neck. And is inserted into the groove 321. Shaped ratchet groove may be formed at the end of the neckband 310. The ratchet groove is engaged with the neckband 310 inserted into the coupling groove 321 and the inner side of the adjustment knob 322 .

Therefore, after the user inserts the neckband 310 into the binding groove 321 of the connecting body 320, the user freely loosens the neckband 310 by rotating the adjusting knob 322 with one hand It becomes possible to tighten. However, in the present invention, it is most easy to adjust the fastening state of the neckband 310 by only one hand adjustment. However, in the present invention, It is very convenient to adjust.

On the other hand, a support wing 330 is formed on one side of the connection body 320 to support the back of the user's neck. The support wing 330 is preferably provided with two wings so as to naturally wrap the two sides of the neck, And may be connected to the connection body 320 in a hinge structure so as to be able to flow naturally.

The back support unit 500 is formed with a fixing surface 510 fixed to one side of the generator unit 200, that is, the inside (user side) of the generator unit 200 so as to be supported below the user's neck, A cushion 511 made of an elastic material is provided on the fixing surface 510 and is brought into close contact with the lower part of the user's neck. In addition, a shoulder-gripping wing 520 having a curved shape is extended from both sides of the fixing surface 510 so as to be seated on the shoulder portion of the user.

A long hole 530 is formed in the horizontal direction on the fixing surface 510 and the coupling protrusion 540 is coupled to one side of the generator unit 200 through the long hole 530, (530).

This is because when the user turns the face to the left or right while wearing the mask unit 100 on the face, the back support unit 500 seated on the shoulder does not flow in a state fixed to the user's shoulder, The mask unit 100, the generator unit 200, the neck support unit 300, the connecting unit 400 and the neckband 310 are turned integrally with the user's head in the left and right directions, The fluidity is given in response to the movement.

In addition, the conventional electric type breathing apparatus has a problem that the filter body is worn on the back of the waist and the long hose is connected to the automatic welding face, so that it is inconvenient to wear because of its large volume and weight, The generator unit 200 may be positioned behind the user's neck so that the distance from the mask unit 100 is minimized while being supported by the neck of the user through the back support unit 500, So that it can be worn.

As described above, according to the present invention, even if the user moves the face vertically or horizontally through the structure of the corrugated pipe 440 and the back support part 500 of the connect part 400, fluidity can be imparted and coped with, . More detailed wear modes of the user will be described in the following drawings.
