Air blowing noise suppresser for airline hood

The present invention relates to an air spray silencer for an airline hood, and more particularly, a safety tool that performs a safety protection cussion function while significantly reducing noise when supplying fresh air to an upper portion of a hard hat, a welding surface, and a protective surface. It relates to an air spray silencer which is applied to.

Generally, an external air supply device (compressor, etc.) and a portable air supply device possessed by an individual are configured with a blower fan and a filter to blow air to the worker, and the supply amount is adjusted step by step as necessary.

Air line hood is installed to supply fresh air from the outside to the inside of the hood.It is installed on safety equipment in the industrial field and is a protective hood that is worn for the safety of workers in the work of sending, shortening, painting and welding. , Safety and so on. In the case of wearing such a hard hat, protective hood, etc., the user continuously supplies fresh air through the air line for smooth breathing of the worker.

When working in an enclosed space of an industrial site, an air line is formed to supply fresh air to the worker, and it is used as a method of forcibly injecting air so that it can be supplied to the worker by using a compressor. There was a problem that the operation efficiency is lowered and can not be easily exchanged.

The problem to be solved by the present invention is to provide an air-jet silencer for the air line hood that is inserted and mounted on the inner surface of the hard hat used in the industrial field while supplying fresh air and minimize the noise to increase the operator's environment. There is a purpose.

Another object of the present invention is to provide a safety equipment used for the operator is to provide an airborne silencer for the airline hood minimized the weight.

Still another object of the present invention is to provide an air hood silencer for an airline hood, which functions as an air cushion in the event of an external impact.

The problem solving means of the present invention constitutes a sound absorbing material inside the disk-shaped tube, fixed with a pressing portion to reduce the swelling when high-pressure air is injected into the disk-shaped tube, the supply hose between the sound absorbing material of the disk-shaped tube It is characterized in that the air is discharged to the outlet of the lower edge of the frame when injecting air.

The disk-shaped tube of the air injection silencer of the present invention was achieved by bonding two elastic pads at high frequency.

The disk-shaped tube of the air-injection silencer of the present invention was achieved by configuring a plurality of wings on the rim surface for convenient contact.

The air injection silencer of the present invention was achieved by forming a disc-shaped tube between the shock absorbers configured inside the helmet and forming a through hole that can be seated on the shock absorber.

When the air injection silencer of the present invention is used in the safety equipment to supply the fresh air to the worker can reduce the noise, the weight is light, there is an effect that the operator can perform the work conveniently.

In addition, it is a useful invention that has a very excellent effect that can act as a shock absorber that can minimize the impact of the outside when acting on the helmet.

Detailed description of the preferred embodiments of the present invention will be described with reference to the drawings.

1 to 6 of the air injection silencer of the present invention is mounted on the upper surface of the safety equipment worn on the head to configure the air supplied from the external air supply device to discharge the air from the upper head cooling effect and air The air injection silencer mounted in the safety tool to provide the best working conditions to the operator to provide a sound absorbing material 150 inside the disc-shaped tube 200, the high-pressure air into the disc-shaped tube Is fixed to the compression unit 110 to reduce swelling during injection, and the supply hose 130 is configured between the sound absorbing material 150 of the disc-shaped tube to the outlet 100 of the lower surface of the border when injecting air There is a feature configured to discharge air.

Airline silencer air spray silencer is equipped with a disc-shaped tube 200, the sound absorbing material 150 and the supply hose 130 so as to minimize the weight while convenient installation of a stabilizer (hat, protective hood, etc.).

The disc-shaped tube 200 is inserted into the sound-absorbing material 150 in a one-piece pocket by pressing with a crimping rivet or combined two elastic pads (110-1) and the sound absorbing material 150 in a preferred embodiment of the present invention Furnace rim 140 and the air passage was bonded by high frequency to constitute an air passage.

The sound absorbing material 150 is a sponge, a high-foam PVC, etc., preferably used as a material of the air flow path is well.

The sound absorbing material has a large cushion and gives a bulk, and fixed with a plurality of compression rivets in the center to prevent the high-pressure air from expanding rapidly when supplied to the disc-shaped tube.

When the disc-shaped tube 200 is prevented from being greatly inflated by the crimping unit 110, the original shape is almost maintained.

The pressing portion shown in Figure 4 to attach the two elastic materials, such as high-pressure bonding to heat and press the compression rivets consisting of upper and lower rivets (120-1,120-2) and rubber rings (120-3) to heat and press Configured.

When the rubber ring is inserted between the crimping rivets, the crimping strength is increased to prevent leakage or seizure of the joint.

The discharge port 100 of the air is formed in the disc-shaped tube to discharge the air, the discharge angle (θ) of the air should be formed within 90 degrees rather than the vertical direction, but the present invention is the discharge angle as the disc-shaped tube is inflated Is formed within 90 degrees, it is preferable to allow the air to be discharged around 45 degrees in the correct embodiment.

Therefore, the present invention is configured to discharge the disc in the outward direction as the disc-shaped tube swells when the outlet is formed on the bottom surface of the rim surface.

The disc-shaped tube of another embodiment of the present invention is a high-frequency adhesive to the air frame by constructing an air flow path by adhering the edge 140 and the air flow path in a state where two elastic pads 100-1 and the sound absorbing material 150 are placed. There are features arranged and arranged.

 The disc-shaped tube of the present invention is configured to be in close contact with the hard hat by configuring a plurality of wings 120 on the rim.

When mounted to the helmet 300 shown in Figures 5 and 6, the disc-shaped tube 200 is configured between the shock absorber 230 configured in the interior of the hard hat, and the through hole that can be seated in the shock buffer ( 210 and a wing seating groove 220 capable of seating the wing has a feature.

As described above, when the protective gear is prevented from being pushed, there is an effect of reducing an external impact.

Another embodiment shown in Figure 7 of the present invention is configured to supply air in a wide range by configuring the air supply passage 260 and the outlet 100 in the blade 120 of the disc-shaped tube.

The fixing band 190 is seated to fix the supply hose 130 connected to the disc-shaped tube 200 to the hard hat 300 when the air injector silencer of the present invention shown in FIGS. 5 and 6 is worn on the hard hat. Consists of the groove 160 and the fitting protrusion 170 and the fixing bracket 180 was coupled to the fitting groove 280 of the hard hat 300.

The air injection silencer of the present invention is so important that the supply of fresh air from outside in an industrial site working in a difficult environment is so important that the fresh air is sprayed evenly in the safety tool to feel cool and discharge the internal heat to the outside, The operator was able to reduce the noise dramatically by putting the weight on the operator.

As described above, the present invention has been described with reference to the embodiment illustrated in the drawings, but this is only an example, and those skilled in the art may make various forms of deformation and other equivalent embodiments therefrom. Will understand. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
