[0031] Combine the following Figure 1-Figure 5 The technical solution provided by the utility model is described in more detail.
[0032] Embodiment 1:
[0033] The utility model provides an air guide structure, including a shell 1, an air inlet 101 and an air outlet 102 located on the shell 1, wherein a driving mechanism and an air guide plate 5 are arranged in the shell 1, wherein: the driving mechanism is located above the air guide plate 5, and is used to allow external air to enter the shell 1 through the air inlet 101; a flow guide structure 51 is arranged on the air guide plate 5, and an air guide port 52 is arranged on the side wall of the flow guide structure 51, and the air guide port 52 is arranged toward the air outlet 102, and the air outlet 102 is an annular port, and the airflow passing through the air guide port 52 can carry mist and be blown out from the air outlet 102 at 360 degrees.
[0034] The driving mechanism includes a fan 4, which is fixed in the housing 1. When the fan 4 rotates, it drives the external airflow to enter the housing 1 from the air inlet 101. The air inlet 101 is arranged in a fan-shaped interval to ensure the air intake.
[0035] See also Figure 1 and Figure 2 As shown, a mounting plate 8 is fixed on the top of the shell 1. After the entire ultrasonic dust reduction device is fixed by the mounting plate 8, the airflow passing through the air guide port 52 can carry the mist and blow it out 360° from the air outlet 102. The mist can be discharged in a 30° direction, and dust reduction can be performed in multiple directions.
[0036] The utility model provides an air guide structure and a driving mechanism to drive the external air flow into the shell 1 through the air inlet 101, and the air flow is blown out from the air guide port 52 through the guide structure 51 on the air guide plate 5. The guide structure 51 can guide the direction of the air flow, reduce wind loss, and prevent the air flow from being turbulent in the shell 1. The air flow passing through the air guide port 52 can carry the mist and be blown out from the air outlet 102 at 360°, and the mist can be discharged in a 30° direction, and dust can be reduced in multiple directions, thereby improving the dust reduction efficiency and effect.
[0037] As an alternative embodiment, see Figure 2 and Figure 3 As shown, the air outlet 102 is arranged around the air guide plate 5 .
[0038] The airflow is blown out from the air guide port 52 through the air guide structure 51 on the air guide plate 5, and is blown out 360 degrees from the air outlet 102 at the periphery of the air guide plate 5, which can reduce airflow loss.
[0039] As an alternative embodiment, see Figure 3 and Figure 4 As shown, the air guide structure 51 of this embodiment includes a groove, the opening side of the groove is arranged toward the driving mechanism, and the air guide port 52 is located on the side wall of the groove.
[0040] Under the action of the fan 4, the airflow enters the housing 1 through the air inlet 101, enters the groove from the opening side, and then blows from the air guide 52 on the side wall of the groove to the air outlet 102. The flow guide structure 51 can guide the flow direction of the airflow, so that the airflow in the housing 1 flows to the air outlet 102, reducing the generation of vortices and reducing airflow noise.
[0041] As an alternative embodiment, see Figure 4 As shown, the grooves are evenly spaced on the air guide plate 5, and the grooves include a central groove 512 and side grooves 511. The side grooves 511 are arranged around the central groove 512, and at least one air guide port 52 is arranged on each side wall of the central groove 512. At least one air guide port 52 is arranged on the side wall of the side groove 511 facing the air outlet 102.
[0042] Air guide ports 52 are arranged on all side walls of the central groove 512 located in the middle, and air flow can be blown out to the surroundings from the central position of the air guide plate 5. In the side groove 511 which is offset from the center, an air outlet 102 is arranged on one side toward the adjacent air outlet 102. In this way, the air flow can flow to the air outlets 102 at different positions according to the set direction, thereby reducing the impact of multiple air flows, reducing the generation of vortices, and reducing air flow noise.
[0043] As an alternative embodiment, see Figure 2 , Figure 3 and Figure 5 As shown, a backflow prevention plate 3 is also provided in the shell 1, and the backflow prevention plate 3 is located above the driving mechanism. The backflow prevention plate 3 and the shell 1 enclose a cavity 7 for accommodating electrical components. The backflow prevention plate 3 is provided with an anti-backflow hole. The backflow prevention plate 3 is provided with an anti-backflow hole that allows airflow to pass through, and the side wall of the anti-backflow hole is used to prevent the mist droplets from rising.
[0044] See also Figure 2As shown, the cavity 7 enclosed by the anti-backflow plate 3 and the inner wall of the housing 1 is used to accommodate electrical equipment, such as a single-chip microcomputer, etc., and can prevent airflow from flowing back and causing a short circuit in the electrical equipment.
[0045] As an alternative embodiment, see Figure 5 As shown, the backflow prevention plate 3 includes a plate body and an inclined plate fixed on the plate body. The inclined plate is inclined relative to the horizontal plane. All inclined plates are fixedly connected by partitions. The backflow prevention holes are formed between adjacent inclined plates. The backflow prevention holes are fan-shaped holes, and all the backflow prevention holes are arranged with a common center.
[0046] The rising backflow mist will hit the inclined plate, condense on the inclined plate, and be blocked by the inclined plate, and the condensed water droplets fall into the water tank 2. The airflow from the air inlet 101 to the anti-backflow plate 3 can flow downward through the anti-backflow hole. The anti-backflow plate 3 does not affect the air entering the drainage structure 51 under the premise of preventing the backflow of water vapor.
[0047] Embodiment 2:
[0048] This embodiment provides an ultrasonic dust suppressor, including a shell 1, a water tank 2 and the above-mentioned air guide structure, an ultrasonic oscillator 6 for generating water mist is fixed in the water tank 2, and an air outlet 102 is formed between the shell 1 and the water tank 2.
[0049] The ultrasonic oscillator 6 is an existing mature device, which uses the high-frequency vibration of ultrasonic waves to act on the liquid to generate cavitation effect and surface tension waves, thereby forming tiny droplets.
[0050] As an optional implementation, a light strip is fixed on the inner wall of the housing 1 .
[0051] For details, see Figure 2 As shown, the light strip can be fixed between the air guide plate 5 and the inner wall of the housing 1, which is not shown in the figure. The light strip can form a lighting effect when the fog is discharged, which is more beautiful.
[0052] As an alternative embodiment, see Figure 2 As shown, a lip 21 is provided on the outer circumference of the water tank 2, and the lip 21 extends in a direction away from the axis of the water tank 2. When the mist carries the liquid droplets out of the air outlet 102, it will be blocked by the lip 21 and flow back to the water tank 2. In this way, the mist is ensured to flow out of the air outlet 102 with the air flow as much as possible, and the escape of the liquid droplets is reduced.
