[0002] In some factories, air outlet pipes and air inlet pipes are provided for indoor ventilation. An axial flow air guide hood is provided at the end of the air inlet pipe. Since the air guide hood is located on the indoor ceiling, sound-absorbing cotton is provided in the air guide hood. However, most of the sound-absorbing cotton is installed on the inner side wall of the air guide hood, and a large area of the axial direction of the air guide hood is still in a gap state, resulting in the noise generated by the air entering the room not being mostly reduced. For this reason, we propose a flow guiding and noise reducing air guide hood. Utility Model Content

[0003] Aiming at the deficiencies of the prior art, the purpose of this patent is to provide a flow guiding and noise reducing air guide hood. In this patent, a sound-absorbing cotton cylinder is provided on the inner side wall of the air guide hood body. The bottom of the air guide hood body is connected with a sound-absorbing cotton layer through a pressing ring. The sound-absorbing cotton layer is provided with small holes. Since the sound-absorbing cotton layer is located at the cross-section position of the air guide hood body, it avoids a large area of the axial direction of the air guide hood body being in a gap state and ensures the noise reduction effect.

[0004] The technical solution adopted by this patent to solve its technical problems is: a flow guiding and noise reducing air guide hood, including an air guide hood body. A sound-absorbing cotton cylinder is sleeved on the inner side wall of the air guide hood body.

Specific Embodiments

[0017] The following combines specific embodiments to further elaborate on this patent. It should be understood that these embodiments are only used to illustrate this patent and not to limit the scope of this patent. In addition, it should be understood that after reading the content taught in this patent, those skilled in the art can make various changes or modifications to this patent, and these equivalent forms also fall within the scope defined by the appended claims of the application.

[0018] See Figure 1 、 Figure 2and Figure 3 Figure 0 is a schematic structural diagram of this patent. A flow guiding, noise reducing and air guiding cover includes an air guiding cover body 1. A sound absorbing cotton cylinder 2 is sleeved on the inner side wall of the air guiding cover body 1. The outer diameter of the sound absorbing cotton cylinder 2 matches the inner diameter of the air guiding cover body 1. A sound absorbing cotton layer 3 is provided at the bottom of the air guiding cover body 1. The bottom of the sound absorbing cotton cylinder 2 is attached to the top of the sound absorbing cotton layer 3;

[0019] Small holes 4 are provided on the sound absorbing cotton layer 3. The sound absorbing cotton layer 3 is circular. An annular part 5 is integrally formed on the outer side wall of the sound absorbing cotton layer 3. A pressing ring 6 is attached to the bottom of the annular part 5. Connecting plates 7 are fixedly installed at both the left and right ends of the outer side wall of the pressing ring 6. Elastic members 8 are provided at both the left and right ends of the outer side wall of the air guiding cover body 1. The bottom end of the elastic member 8 is connected to the top of the connecting plate 7. The top of the annular part 5 is closely attached to the bottom of the air guiding cover body 1.

[0020] Specifically, the small holes 4 are curved.

[0021] By setting the small holes 4 to be curved, the frequent contact between the air flow to enter the room and the inside of the sound absorbing cotton layer 3 can be increased, improving the noise reduction effect.

[0022] Specifically, the inner diameter of the pressing ring 6 is larger than the outer diameter of the sound absorbing cotton cylinder 2.

[0023] By the inner diameter of the pressing ring 6 being larger than the outer diameter of the sound absorbing cotton cylinder 2, it is convenient to take out the sound absorbing cotton cylinder 2 downward from inside the pressing ring 6.

[0024] Specifically, the elastic member 8 includes a column 9. The outer side wall of the column 9 is fixedly installed on the outer side wall of the air guiding cover body 1. A columnar cavity 10 is provided inside the column 9. A round hole 11 is provided in the middle of the bottom wall of the columnar cavity 10. An upper ring body 12 is integrally formed on the top wall of the columnar cavity 10. A sliding plate 13 is slidably installed on the inner side wall of the columnar cavity 10. A lower ring body 14 is integrally formed on the top of the sliding plate 13. An elastic cord 15 is connected between the upper ring body 12 and the lower ring body 14. A vertical rod 16 is fixedly installed at the bottom of the sliding plate 13. The bottom end of the vertical rod 16 passes through the round hole 11 and is fixedly installed on the top of the connecting plate 7.

[0025] Figure 2 As shown, the elastic cord 15 is in a stretched state. Through the rebounding effect of the elastic cord 15, an upward pressure exists on the connecting plate 7 and the pressing ring 6, fixing the sound absorbing cotton layer 3 at the bottom of the air guiding cover body 1.

[0026] Specifically, the column 9 includes a vertical pipe 17, a round plate 18 and a ring 19. The bottom of the round plate 18 is fixedly installed at the top end of the vertical pipe 17. The top of the ring 19 is fixedly installed at the bottom end of the vertical pipe 17.

[0027] Such as Figure 3As shown, by dividing the upright column 9 into a vertical pipe 17, a circular plate 18, and a circular ring 19, it is convenient to open the cylindrical cavity 10 in the early stage and also facilitate the early installation of the internal structure of the upright column 9.

[0028] Specifically, a hinge seat 20 is fixedly installed at the bottom of the circular ring 19, and a support rod 21 is connected in the hinge seat 20 through a rotating shaft.

[0029] When disassembling or installing the sound-absorbing cotton layer 3, the pressing ring 6 and the connecting plate 7 can be moved downward. After a certain distance, the support rod 21 can be rotated to the vertical state, so that the bottom end of the support rod 21 supports on the top of the connecting plate 7. At this time, the position of the pressing ring 6 can be fixed, which is convenient for taking out and placing the sound-absorbing cotton layer 3.

[0030] Working principle: The top end of the air guide hood body 1 can be fixed at the end of the indoor air inlet pipe. The outdoor air flow enters the air guide hood body 1 through the drainage system. The air flow is subjected to noise reduction treatment through the sound-absorbing cotton cylinder 2 and the sound-absorbing cotton layer 3. The sound-absorbing cotton layer 3 is located at the cross-sectional position of the air guide hood body 1, so it avoids a large area of the axial direction of the air guide hood body 1 being in a gap state, ensuring the noise reduction effect.

[0031] When the dust in the sound-absorbing cotton cylinder 2 and the sound-absorbing cotton layer 3 is seriously blocked, the pressing ring 6 can be moved downward. After a certain distance, the support rod 21 can be rotated to the vertical state, so that the bottom end of the support rod 21 supports on the top of the connecting plate 7. Then, the sound-absorbing cotton layer 3 is taken out from the gap between the pressing ring 6 and the air guide hood body 1, and the sound-absorbing cotton cylinder 2 is taken out downward from the pressing ring 6 for replacement.

[0032] It should be noted that the device structure and drawings of this patent mainly describe the principle of this patent. On the basis of this design principle, the settings of the power mechanism, power supply system, and control system of the device are not fully described clearly. However, on the premise that those skilled in the art understand the principle of the above patent, the specific details of its power mechanism, power supply system, and control system can be clearly known.

[0033] In this patent, the inner side wall of the air guide hood body is provided with a sound-absorbing cotton cylinder. The bottom of the air guide hood body is connected with a sound-absorbing cotton layer through a pressing ring. The sound-absorbing cotton layer is provided with small holes. Since the sound-absorbing cotton layer is located at the cross-sectional position of the air guide hood body, it avoids a large area of the axial direction of the air guide hood body being in a gap state, ensuring the noise reduction effect.
