[0029] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0030] refer to Figure 1 , Figure 2 as well as Figure 3As shown, a chicken house for breeding according to an embodiment of the utility model includes a closed chicken house (not shown in the figure) and a fresh air system connected to the closed chicken house, the fresh air system includes an air intake room 10 and an air intake fan (not shown in the figure) arranged in the air intake room 10, the air intake room 10 is connected to the closed chicken house through an air intake duct 20; the air intake room 10 is provided with a plurality of air flow channels 30 connecting the inside and outside of the air intake room 10, and a noise reduction structure is arranged on the circumference of the air flow channel 30, the noise reduction structure includes a plurality of chambers, and the chambers are all provided with openings 33 connected to the air flow channel 30.

[0031] In actual production and use, the air intake room 10 is provided to reduce the diffusion of the noise generated by the air intake fan. At the same time, the existence of the noise reduction structure can ensure that the air intake room 10 can take in air while also reducing the noise of the air intake fan.

[0032] Specifically, Figure 4 as well as Figure 5 The direction of the middle arrow is the flow direction of the gas in the gas flow channel 30 .

[0033] refer to Figure 2 , Figure 3 as well as Figure 4 Specifically, multiple chambers are arranged in sequence along the length direction of the airflow channel 30. Preferably, there are multiple noise reduction structures and they are arranged around the airflow channel 30. More preferably, the openings 33 of different noise reduction structures in the same sequence are staggered. For example, if there are two noise reduction mechanisms, and the chambers of each noise reduction mechanism are arranged at equal intervals and are three in number, then the first chamber of one of the noise reduction mechanisms is farther from the end of the airflow channel 30 close to the outside world than the first chamber of the other noise reduction mechanism, thereby forming a staggered position.

[0034] refer to Figure 4 In some embodiments, the chamber includes a first chamber 31 and a second chamber 32 which are spaced apart, and the second chamber 32 is filled with a sound absorbing material 34. The sound absorbing material 34 is a sound absorbing cotton commonly used in the prior art. Through the above arrangement, after the sound waves flow into the second chamber 32, the sound energy is absorbed by the sound absorbing material 34, thereby achieving a higher noise reduction effect.

[0035] The above noise reduction structure forms an acoustic bandgap between the airflow channel 30 and the air intake fan by adopting the Bragg scattering principle of the acoustic superstructure. Based on the acoustic bandgap effect, the noise of the air intake fan is suppressed. Moreover, after the sound wave enters the airflow channel 30, it achieves the purpose of noise reduction through multi-path diffraction and multi-stage Helmholtz resonance. At the same time, the above airflow channel 30 does not affect the flow of air and can meet the smooth passage of airflow.

[0036] In some preferred embodiments, the fresh air system further includes an exhaust room (not shown in the figure) and an exhaust fan (not shown in the figure) disposed in the exhaust room, and the exhaust room is connected to the closed chicken house through an exhaust pipe (not shown in the figure). By matching the exhaust fan with the intake fan, the airflow in the closed chicken house can be better adjusted, and the working intensity of the exhaust fan and the intake fan can be reduced, thereby extending the service life.

[0037] Specifically, the structure of the exhaust room is the same as that of the air intake room 10. Through the above design, the spread of the noise generated by the exhaust fan can be reduced, and the existence of the noise reduction structure can ensure that the exhaust room can exhaust while also reducing the noise of the exhaust fan.

[0038] refer to Figure 5 In some preferred embodiments, the second chamber 32 of the exhaust room is also filled with activated carbon 35. The sound absorbing material 34 is closer to the opening 33 than the activated carbon 35. Through the above design, the gas in the closed chicken house extracted by the exhaust fan in the exhaust room can contact with the activated carbon 35 when passing through the air flow channel 30 on the exhaust room, thereby absorbing the odor contained in the gas and then discharging it to the outside, thereby effectively reducing the impact of the chicken house on the outside.

[0039] In some specific embodiments, the outer periphery of the air intake pipe and the exhaust pipe are coated with a heat-insulating and sound-absorbing layer (not shown in the figure). Specifically, the heat-insulating and sound-absorbing layer is pearl cotton. Preferably, by coating the air intake pipe and the exhaust pipe with pearl cotton, the sound generated by the air flow in the pipe hitting the pipe wall can be effectively reduced, and the influence of the environment on the temperature in the pipe can be reduced. More preferably, the inner walls of the air intake pipe and the exhaust pipe are filled with pearl cotton.

[0040] Preferably, the chamber near the air intake room 10 is the first chamber 31, and the chamber near the air intake room 10 is the second chamber 32. For the exhaust room, the chamber near the exhaust room is the second chamber 32, and the chamber near the exhaust room is the first chamber 31.

[0041] In some specific embodiments, both ends of the airflow channel 30 are in a bell-mouth structure. With this design, the airflow throughput through the airflow channel 30 can be increased.

[0042] In summary, the air intake room 10 is provided to form a cover to cover the air intake fan, thereby reducing the diffusion of the noise generated by the air intake fan. At the same time, the existence of the air flow channel 30 with the noise reduction structure can ensure that the air intake room 10 can take in air while also reducing the noise of the air intake fan. At the same time, the exhaust room and the exhaust fan are also provided with the same design to reduce noise. At the same time, the exhaust fan can reduce the working intensity of the air intake fan, thereby extending its service life.

[0043] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
