SAFETY WARNING SYSTEM FOR AIR BREATING APPARATUS}

The present invention relates to a safety alarm system for an air breathing apparatus, and more particularly, to a safety breathing system for an air breathing apparatus that warns the remaining amount of air by the air pressure of the air breathing apparatus for supplying the air of the reservoir to the mask.

In general, workers who work in places where air is scarce, such as fire sites or harmful gas sites, are equipped with a reservoir that supplies air to the mask, and the air is breathed by an air breathing device consisting of a backpack (Bcakpack) worn on the back. Get supplied. That is, the worker is supplied with the air of the air reservoir constituting the air breathing apparatus as a mask. Such an operator recognizes the amount of air available (alarm remaining) for about 5 minutes by an alarm operated by the air pressure in the reservoir. Thus, the operator can quickly evacuate to a safe place rich in air for about 5 minutes.

The air breathing apparatus described above is most representative of the registration No. 10-951394 (name: air safety alarm system) registered in the Korean Patent Office by the applicant of the present invention. This conventional air breathing apparatus is a high-pressure primary air having a pressure of about 300kgf / cm ² by the regulator 2, the air in the reservoir (not shown) mounted on the backpack 53 as shown in FIG. After being converted into a low pressure secondary air having a pressure of about 8 kgf / cm ² , it is supplied to the distributor 60 through the first tube 2a and the second tube 2b. The primary air and the secondary air are respectively supplied to the remaining gauge 55 and the mask 57 provided with the lamp 72b on the handle 80 through the gauge tube 55a and the air supply tube 57a. Therefore, the worker can breathe through the air flowing into the mask 57, and can check the remaining amount of the reservoir through the remaining gauge (55).

Here, when the air in the reservoir reaches the warning remaining amount and the air pressure of the second tube 2b is weakened, the distributor 60 may whistle a part of the secondary air through the whistle tube 59a as shown. 59) to emit a beep.

In addition, the backpack 53 described above is provided with a warning light 72a at the lower end as shown. This warning light 72a is operated by a battery (not shown) embedded in the side battery box.

On the other hand, the mask 57 has a built-in microphone (not shown) connected to the speaker not shown. Therefore, the operator can transmit the voice to the outside while wearing the mask 57.

On the other hand, the dispenser 60 is fixed to the fixing hole 53a of the backpack 53 by the screw SC with the switching member 74 installed at the rear as shown in FIG. As shown in the dispenser 60, the first tube 2a and the second tube 2b are connected to the lower portion of the block 62 constituting the main body, and the gauge hole 62a formed on the upper portion of the block 62. The gauge tube 55a and the air supply tube 57a and the whistle tube 59a are connected to each other through the respiratory pores 62b and the whistle holes 62c.

As shown in FIG. 3, the switching member 74 includes a case 74c having a pair of tact switches 74a and a pair of diaphragms DP corresponding to the tact switch 74a. It is mounted on the back. At this time, the diaphragm DP communicates with the respiratory pores 57a and the whistle holes 59a of the distributor 60 and is installed in the communication holes 62d through which the above-described secondary air is communicated.

As shown in FIG. 4, the distributor 60 has a hollow sharing path HP horizontally formed at the center in a direction orthogonal to the gauge hole 62a, the respiratory hole 62b, and the whistle ball 62c. The hollow sharing path HP does not communicate directly with the gauge hole 62a, the respiratory hole 62b, and the whistle hole 62c, but communicates through the through holes 62a 'and 62b'.

Dispenser 60 is after the primary air of the first tube (2a) flows into the gauge hole (62a), a part is supplied to the gauge tube (55a) through the gauge hole (62a), the other part of the through hole ( 62a ') to feed the heavy share (HP). Then, the distributor 60 is the secondary air of the second tube (2b) is introduced through the respiratory pores (62b), a part of which is supplied to the air supply pipe (57a) through the respiratory pores (62b), the other part is It is supplied to the heavy shared path HP through another through hole 62b '. Therefore, the remaining amount gauge 55 described above displays the remaining amount of the reservoir by the primary air supplied to the gauge tube 55a. Then, the mask 57 receives the secondary air through the air supply pipe (57a).

On the other hand, some of the primary air (high pressure air) introduced into the through-hole (62a ') is a cap that shields one end of the heavy sharing passage (HP) through the heavy sharing passage (HP), as shown in the enlarged view "b" ( It flows into the bypass flow path 64a of 64 and pressurizes the plunger 66b. At this time, the plunger 66b moves while compressing the spring 66a that elastically supports the flange 66b ', and then shields the whistle hole 62c in communication with the hollow sharing path HP. Therefore, the whistle hole 62c is shielded by the plunger 66b when the pressure of the primary air is strong.

However, the plunger 66b returns to its original position as shown in the enlarged view "a" by the elastic force of the spring 66a when the air in the reservoir is exhausted and the pressure of the primary air is weakened. At this time, the whistle ball (62c) is opened while supplying the primary air of the heavy sharing path (HP) to the whistle pipe (59a) to operate the above-described whistle (59). Therefore, the operator can confirm that the air in the reservoir has reached the remaining amount of warning through the warning sound of the whistle 59.

Here, the above-described plunger 66b shields the bypass flow path 64a of the cap 64 as shown in the enlarged view "A" so that the primary air is another through hole 62b 'and the communication hole 62d. To prevent communication) That is, the primary air cannot communicate with another through hole 62b 'and the communication hole 62d.

On the other hand, the secondary air is partially introduced into the heavy sharing path HP through another through hole 62b 'and then exhausted to the communication hole 62d. At this time, the secondary air convexly expands any one diaphragm DP maintaining a flat state as shown in the enlarged view "C", as shown in the enlarged view "D". That is, the secondary air is discharged to the communication hole 62d from the heavy sharing path HP to expand the diaphragm DP. At this time, the diaphragm DP presses the tact switch 74a as shown enlarged. Therefore, the switch module 74b activates and flashes the above-mentioned warning light 72a. That is, the warning light 72a operates at the same time as the secondary air is supplied to the heavy sharing path HP to indicate the location of the worker.

On the other hand, when the whistle ball 62c is opened by the movement of the plunger 66b as shown in the enlarged view “a”, the secondary air of the hollow sharing path HP flows in. At this time, the secondary air introduced into the whistle ball (62c) flows into another communication hole (62d) formed in the whistle ball (62c), as shown in the unexpanded view, and then another diaphragm (DP) Magnification is also convexly expanded as shown in " D ". Therefore, another diaphragm DP presses another tact switch 74a to light the lamp 72b of the remaining amount gauge 55 described above. That is, another diaphragm DP operates the lamp 72b together when the whistle 59 is operated.

However, in the conventional air breathing apparatus, since the warning lamp 72a is automatically operated by the switch module 74b only when the air in the reservoir reaches the warning remaining amount, the warning lamp 72a is manually turned on in a dangerous situation by the operator. There is a problem that cannot be done. Therefore, the worker cannot confirm his position to other workers in a dangerous situation.

In addition, since the warning lamp 72a or the lamp 72b is turned on by the diaphragm DP, a large number of parts must be provided.

In addition, since the remaining amount of the battery for operating the warning light 72a cannot be confirmed, the warning light 72a which is turned on at the rear of the backpack 53 may not operate due to the exhaustion of the battery.

In addition, the remaining amount of air in the reservoir can not be confirmed inside the mask 57, there is also a hassle to check the remaining gauge 55 from time to time.

In addition, the weight of the mask 57 is increased because a battery for operating the microphone must be separately installed inside or outside the mask 57 to operate the aforementioned microphone inside the mask 57. In particular, the weight of the mask 57 is greatly increased because the battery is configured in size AA or more for stable operation of the microphone.

In addition, since the air supply pipe 57a is not separated from the distributor 60 or the mask 57, the mask 57 cannot be separately stored and stored, which causes inconvenience in storage.

Meanwhile, reference numeral 81 in the enlarged view of FIG. 1 is a case, 82 is a protective wall for protecting the lamp 72b, and reference numeral 66 in FIG. 2 is a valve member including a plunger 66b.

In addition, reference numeral SV of FIG. 2 is a screw valve shielding one end of the whistle hole 62c, and 62e is a fastening hole to which the screw valve SV is fastened.

Rotating ring 270 has a shield wing (CW) extending from one end as shown. The shielding wing CW is the remaining component of the above-described winding space providing means having the winding sheet 263 and shields the winding sheet 263 formed on the hollow shaft 260 as shown. Of course, the winding sheet 263 is the additional wire (S2) is wound as shown. Therefore, the winding space providing means provides the concealed winding space to the additional wire (S2).

On the other hand, the additional wire (S2) is introduced into the rotary ring 270 in a concealed state through the wire hole (WH) of the wire guider (GD) formed in the rotary ring 270, as shown in the projection ring 290 It is guided to the ring holder 240 through the above-described cut-out groove 292 is connected to the terminal (T) of the ring holder 240. And, the additional wire (S2) is a ring holder when the positive pressure regulator 200 is coupled to the clamp 320 of the exhaust port 300 described above so that the clamp connector 321 of the clamp 320 is coupled to the ring holder 240. Power is applied to the clamp connector 321 through the terminal T of 240.

The operation of the components installed in the mask 130 as described above will be described with reference to the accompanying drawings.

Referring to FIG. 15, an electronic device such as the lamp unit 190 or the microphone 340, which is incorporated in the mask 130, is applied to an additional wire applied through the terminal T of the connector ring holder 240. It is operated by the power supply or the control signal of S2. In this case, the power or control signal is applied through the clamp connector 321, the socket connector 323, the port connector 316, and the terminal connector 342. That is, the electronic device operates as power or a control signal is applied through a carrier formed of the connectors 321, 323, 316, and 342. Therefore, since the wiring of the port frame 310 or the clamp 320 of the exhaust port 300 is minimized by the connector, the electronic device can be stably supplied with the power supply failure caused by disconnection or wire aging. have. Of course, the exhaust port 300 may be easily assembled and manufactured because wiring is minimized.

Referring to FIG. 16, as shown in the ring holder 240, the coupling protrusion 241 of one side is fitted into the coupling hole 219 of the positive pressure regulator 200, and the other side of the ring holder 240 is connected to the positive pressure regulator by the fastening screw 250. Since it is fixed to the 200 is easily assembled to the positive pressure regulator (200). In addition, since the additional connection pipe 132b is pivoted about the hollow shaft 260 by the rotating ring 270 that is inserted into the hollow shaft 260, the additional connector tube 132b can flexibly cope with the flow of the mask 130 described above. . That is, the additional connecting pipe 132b rotates when the mask 130 flows so that the additional connection pipe 132b does not interfere with the work activity of the wearer.

Referring to FIG. 18, the hollow shaft 260 has one side inserted into the positive pressure regulator 200 as shown, and then the fitting protrusion 291 of the protruding ring 290 has the fitting groove 245 of the ring holder 240. As it is coupled to the positive pressure controller 200 is detachably fixed. The hollow shaft 260 is more firmly fixed as one side inserted into the positive pressure regulator 200 is caught by the clip 230. The hollow shaft 260 is rotated with the knob 280 when the knob 280 is rotated to rotate the flow control valve (FV) built in the positive pressure regulator 200 to adjust the flow rate.

The rotary ring 270 is a hollow shaft 260 through the air through hole 260a of the hollow shaft 260 and the communication groove (H) of the inner circumferential surface communicated with each other through the air of the additional connecting pipe 132b introduced through the nipple 271 Guide to the inside of the supply is supplied into the positive pressure regulator 200.

The additional wire S2 is guided into the rotation ring 270 through the wire guider GD formed in the rotation ring 270 as shown, and then wound on the winding sheet 263 of the hollow shaft 260. At this time, the wound additional wire (S2) is concealed by the shielding wings (CW) extending to the rotary ring 270. Therefore, the additional wire (S2) is supplied to the positive pressure regulator 200 in a concealed state. In particular, the additional wire (S2) is supplied to the positive pressure regulator 200 in a more completely concealed state when inserted into the additional connecting pipe (132b) as shown.

Here, the additional connecting pipe 132b and the additional wire (S2) is reduced in weight by the insert processing. That is, the total weight of the additional connecting pipe 132b and the additional wire S2 is reduced. This is because the covering of the additional wire S2 can be omitted. Therefore, since the overall weight can be reduced, it is possible to reduce the fatigue of the operator's neck caused by the feeling of weight during a long time as well as to provide a smooth working condition.

On the other hand, the ring holder 240 when the clamp connector 321 of the clamp 320 is coupled to supply the power of the additional wire (S2) to the clamp 320 through the terminal (T). Therefore, the clamp 320 smoothly supplies a control signal or power to an electronic device such as the microphone 340 or the lamp unit 190 as described above.

Referring to FIG. 19, the rotation ring 270 rotates with the rotation protrusion 273 formed at one side. At this time, the rotary projection 273 is rotated along the other side stopper 224 of the boss shape formed in the positive pressure regulator 200. When the rotary protrusion 273 is rotated to the top of the other stopper 224, the rotation is suppressed while being in close contact with the outer circumferential surface of the other stopper 224 formed to gradually open toward the top. That is, the rotation protrusion 273 may not be excessively rotated upward by the interference of the other stopper 224.

Referring to FIG. 20, when the rotation protrusion 273 is rotated downward, the rotation protrusion 273 is caught by one stopper 222 protruding from the positive pressure controller 200, thereby preventing rotation. That is, the rotation protrusion 273 is not excessively rotated by one side stopper 222. Accordingly, the rotation angle of the rotation protrusion 273 is controlled by one stopper 222 and the other stopper 224 described above. Of course, the rotation angle of the additional connecting pipe (132b) is also controlled accordingly.

As such, the reason for controlling the rotation angle of the additional connection pipe 132b is to prevent disconnection of the additional wire S2 wound inside the rotary ring 270 as shown. This additional wire (S2) is wound about 1.5 times in the interior of the rotary ring 270 as shown to prevent disconnection as much as possible. Therefore, since the additional wire (S2) is extended in length by the number of windings is not tensioned during the rotation of the air supply pipe 132.
