As shown in the figure, the low wind resistance chimney rainproof muffler of the present invention comprises: a body 10; a water collecting tray 20; and a bottom tube 30 combined.

The body 10 is, for example but not limited to, made of metal or plastic, and has a hollow chamber 11 having a first opening 12 at one end and a second opening 13 at the other end. The two side walls of the body 10 are hollow, and are filled with the sound absorbing material 14, and the inner sides of the two side walls respectively have a first sound absorbing surface 15. The sound absorbing material 14 is, for example but not limited to, sound absorbing cotton. In addition, the shape of the body 10 is, for example but not limited to, in the shape of a barrel, and the cross-sectional area near the center is the largest. The cross-sectional area of the first opening 12 is equal to the second opening 13.

In addition, the first sound absorbing surface 15 further has a plurality of micro holes 16 for guiding the airflow discharged by the chimney into the sound absorbing material 14 to achieve the effect of silencing.

The water collecting tray 20 is tapered and disposed in the hollow chamber 11 and has a flashing plate 21 thereon. The flashing plate 21 has a third opening 23, and a drain pipe is connected below the third opening 23. The end portion of the drain pipe 24 is exposed to the body 10 through the second opening 13. The cross-sectional area of the flashing plate 21 is larger than the first opening 12, and the cross-sectional area of the flashing plate 21 is, for example, It is not limited to about 1.2 times of the first opening, so that most of the rainwater entering through the first opening 12 can be collected by the flashing plate 21, and the two sides of the water collecting tray 20 and the body 10 respectively have A first channel 25 and a second channel 26. The flashing 21 has a tapered shape and is inclined toward the center to collect rainwater.

The space of the water collecting tray 20 except the drain pipe 24 is also filled with the sound absorbing material 27, and each of the two sides of the water collecting tray 20 has a second sound absorbing surface 28. The sound absorbing material 27 is, for example but not limited to, sound absorbing cotton.

In addition, the second sound absorbing surface 28 further has a plurality of micro holes 29, The micro holes 29 guide the airflow discharged from the chimney into the sound absorbing material 27 to achieve the effect of silencing.

The bottom tube 30 is disposed below the body 10 and is connectable to the body 10 via the second opening 13. The other end of the bottom tube 30 is connectable to a chimney 60. The bottom tube 30 is, for example but not limited to, a metal tube. In addition, the bottom tube 30 and the chimney 60 are connected by a connection method blue 40.

In addition, the low wind resistance chimney rainproof muffler of the present invention further has a fixed stand 50 disposed between the body 10 and the bottom tube 30, such as but not limited to being made of metal, and The hollow water flowing downward through the first passage 25 and the second passage 26 can be discharged through the fixed base 50; the airflow discharged from the chimney 60 can pass through the first sound absorbing surface 15 and The second sound absorbing surface 28 absorbs sound to achieve a sound absorbing effect.

Therefore, after the combination, the low wind resistance chimney rainproof muffler of the present case, most of the rainwater entering through the first opening 12 can be collected by the flashing plate 21, and then discharged out of the body 10 via the drain pipe 24, and less Part of the rainwater passes through the first passage 25 and the second passage 26, and is discharged out of the body 10 via the drain pipe 24, so that the waterproof effect can be achieved. The airflow discharged by the chimney 60 can be sound absorbing through the first sound absorbing surface 15 and the second sound absorbing surface 28 to achieve a sound absorbing effect. Therefore, the low wind resistance chimney rain-proof silencer in this case is indeed more advanced than the conventional rain-proof chimney.

Please refer to FIG. 5 , which is a schematic diagram showing the flow direction of rainwater of a low wind resistance chimney rainproof muffler according to a preferred embodiment of the present invention. As indicated by the arrow in the figure, most of the falling rainwater enters the body 10 via the first opening 12, and is collected by the flashing plate 21, and then discharged out of the body 10 via the drain pipe 24, and a small portion is Wind-blown oblique rain After the first sound absorbing surface 15 and the second sound absorbing surface 28 are hit, the first channel 25 and the second channel 26 are further down through the second opening 13 and discharged out of the body 10, so that it is indeed Reach the waterproof effect.

Please refer to FIG. 6 , which is a flow chart showing the flow direction of the low wind resistance chimney rainproof muffler according to a preferred embodiment of the present invention. As shown by the arrow in the figure, the airflow discharged from the chimney 60 enters the body 10 via the second opening 13, because the cross-sectional area near the center of the body 10 is the largest, and therefore the airflow entering the body 10 is very high. Small, the airflow is guided to the sound absorbing materials 14, 27 via the first channel 25 and the second channel 26, respectively, by the plurality of micro holes 16, 29 on the first sound absorbing surface 15 and the second sound absorbing surface 28, via the sound absorbing material. After the sound is silenced 14, the body 10 is discharged through the first opening 12. Therefore, the low-resistance chimney rain-proof silencer in this case will not block the path of airflow operation, nor will it cause pressure loss, and does not have a waterproof cover. Therefore, it will not reflect the noise toward the ground and increase the total noise amount. Therefore, It can really achieve the effect of silence.

In summary, with the implementation of the low wind resistance chimney rainproof muffler of the present case, the body is filled with a sound absorbing material to achieve a sound absorbing effect.

One of the objects of the present invention is to provide a low-resistance chimney rain-proof muffler having a water collecting tray in the body, the drain pan having a drain pipe through which rainwater collected by the water collecting tray can be discharged outside the chimney. To achieve a waterproof effect; the cross-sectional area of the first opening of the body is smaller than the cross-sectional area of the water collecting tray to ensure that most of the rainwater is collected by the water collecting tray and then discharged outside the chimney to achieve a waterproof effect; and the water collecting tray is also filled There are sound-absorbing materials to further achieve the advantages of noise reduction, so this case is indeed more advanced than the conventional rain-proof chimney.

The present invention is the preferred embodiment, and the source is changed or modified locally. Those who are acquainted with the technical idea of the case and who are familiar with the skill can not deduct the patent right of the case.

In summary, the case, regardless of its purpose, means and efficacy, is showing its technical characteristics that are different from the conventional ones, and its first creation is practical, and it is also in line with the new patent requirements. I will be granted a patent at an early date.
