Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the following embodiments and accompanying drawings.

As shown in figure 1, the utility model provides a reduce device of pipeline air current noise, including elasticity gasbag 1 and suction nozzle 2. As shown in FIG. 2, a cavity 15 is formed inside the elastic airbag 1, an air inlet 11 is arranged at one end of the elastic airbag 1, an air outlet 12 is arranged at the other end of the elastic airbag 1, the air inlet 11 and the air outlet 12 are communicated with the cavity 15, and the air inlet nozzle 2 is installed on the air inlet 11. As shown in fig. 3, the intake nozzle 2 has an intake portion 21 and an outlet portion 23, an intake hole 22 is provided on the intake portion 21, an outlet hole 24 is provided on the outlet portion 23, an intake channel is provided in the intake nozzle 2, and the outlet hole 24 is communicated with the intake hole 22 through the intake channel. The device for reducing the noise of the pipeline airflow is arranged in the inflation pipeline, when in work, the airflow of the foreline flows into the air inlet nozzle 2 from the air inlet hole 22, flows through the air inlet channel, flows out of the air inlet nozzle 2 from the air outlet hole 24, enters the cavity 15 of the elastic air bag 1, finally flows out of the air outlet 12 of the elastic air bag 1 and enters the rear-stage pipeline. The fore pipeline and the rear pipeline do not belong to the structure of the device, and the device, the fore pipeline and the rear pipeline together form an inflation pipeline. An air outlet nozzle 3 can be arranged on the air outlet 12 to lead out air flow. It should be noted that the air outlet nozzle 3 is not part of the structure of the device, and is part of the subsequent pipeline. The main innovation of the device for reducing the noise of the pipeline airflow is that the air outlet part 23 is rod-shaped and extends into the cavity 15, so that the air outlet hole 24 is positioned in the cavity 15 and communicated with the cavity 15, and the airflow is sprayed out from the air outlet hole 24 and enters the open cavity 15, and the airflow impact is reduced. Meanwhile, the end part 25 of the air outlet part 23 extending towards the cavity 15 is closed, and the side wall of the air outlet part 23 is provided with a plurality of air outlet holes 24 at intervals, so that the air flow is not directly sprayed into the cavity 15 from the end part 25 of the air outlet part 23, but is sprayed into the cavity 15 from the side direction of the plurality of air outlet holes 24 on the side wall of the air outlet part 23 in a dispersed manner, and the air flow impact is further reduced. Meanwhile, the size of the air inlet end of the air outlet hole 24 is smaller than that of the air outlet end, so that a horn-shaped air outlet hole structure is formed, air flow enters from the smaller air inlet end of the horn-shaped air outlet hole 24 and flows out from the larger air outlet end, the air flow spraying speed is reduced, and air flow impact is further reduced. As shown in fig. 4, the air inlet end and the air outlet end can be designed to be circular to form a conical horn structure, and at this time, the diameter d1 of the air inlet end is smaller than the diameter d2 of the air outlet end.

The device reduces the air flow impact in the inflation pipeline from multiple aspects through a specially designed structure, and is combined with the absorption and buffering effect of the elastic air bag 1 on the air flow impact, so that the pipeline air flow noise in the inflation process of the inflatable pillow is obviously reduced, and the inflation process of the inflatable pillow by the controller 4 is quieter.

In this embodiment, the air outlet 23 may be designed to be cylindrical, and all the air outlet holes 24 are uniformly distributed on the annular sidewall of the air outlet 23. Therefore, the airflow is uniformly sprayed out from the periphery of the annular side wall of the air outlet part 23, the impact of the airflow sprayed out from the air outlet part 23 to all directions is balanced, and the generation of airflow noise is controlled more effectively. The elastic air bag 1 is made of rubber, and the rubber has excellent elasticity, can resist and absorb airflow impact more effectively, and is favorable for reducing noise. Meanwhile, as shown in fig. 5, the inner wall 13 of the elastic airbag 1 may be designed to be filled with the sharp-edged wrinkles 14, and noise may be more effectively absorbed by the sharp-edged wrinkles 14. The elastic air bag 1 is in an ellipsoidal structure, and the air inlet 11 and the air outlet 12 are positioned on the long axis of the elastic air bag 1 and are more in line with the flowing characteristic of the air flow of the inflation pipeline. The air inlet nozzle 2 is further provided with a sealing portion 26, and when the air inlet nozzle 2 is mounted on the air inlet 11, the sealing portion 26 is tightly pressed on the inner wall of the air inlet 11, so that the air inlet 11 is sealed to ensure the air tightness of the inflation pipeline.
