The air inlet 2 and the air outlet diffuser plate 5 are respectively located on the front and back sides of the wall body on which the high efficiency air inlet is installed. Its function is that, through the setting of the wind passage 17 on the wind plate 6 and the adjusting body 8 on the wind volume adjusting plate 7 and the design of the shape of the adjusting body 8, in the state that the adjusting body 8 is located in the wind passage 17, as the distance between the wind plate 6 and the wind volume adjusting plate 7 decreases, the gap between the adjusting body 8 and the wind passage 17 gradually decreases, so that the air volume passing through the gap between the adjusting body 8 and the wind passage 17 changes.

[0029] Specifically, as shown in Figure 2 The maximum cross-sectional area of the adjusting body 8 is smaller than the cross-sectional area of the wind passage 17. Its function is that, through the design of the maximum cross-sectional area size of the adjusting body 8, it can avoid that the adjusting body 8 completely blocks the wind passage 17.

[0030] Specifically, as shown in Figure 1 The wind passage 17 is in a circular shape, and the adjusting body 8 is in a conical or circular truncated shape.

[0031] Specifically, as shown in Figure 1 The wind volume adjusting plate 7 is uniformly distributed with a ventilation hole 9 for air flow.

[0032] Specifically, as shown in Figure 1 The driving structure comprises a threaded hole 10 provided on the wind volume adjusting plate 7 and a screw rod 11 threadedly connected with the threaded hole 10. Its function is that, through the design of the threaded hole 10 and the screw rod 11, in the process of rotating the screw rod 11, the wind volume adjusting plate 7 can be raised or lowered.

[0033] Specifically, as shown in Figure 1 The screw rod 11 penetrates through the box 1 and is connected with a knob 13 coaxially arranged with the screw rod 11 on the section outside the box 1. Its function is that, through the setting of the knob 13, it is convenient to manually adjust the air volume.

[0034] Specifically, as shown in Figure 1As shown in the figure, the flow equalizing plate 3 is in the form of a groove with openings on the front and back sides, and flow equalizing holes 16 are uniformly distributed on the bottom surface of the flow equalizing plate 3. The air passing plate 6 is arranged between the air inlet 2 and the bottom surface of the flow equalizing plate 3, and the air volume adjusting plate 7 is arranged between the air passing plate 6 and the bottom surface of the flow equalizing plate 3. The opposite two side walls of the air volume adjusting plate 7 are in contact with the opposite two side walls of the flow equalizing plate 3, respectively. The top of the flow equalizing plate 3 is fixedly connected in the box body 1. Its function is that, through the size relationship and spatial relationship between the air volume adjusting plate 7 and the flow equalizing plate 3, the rotation of the screw rod 11 can be avoided to cause the rotation of the air volume adjusting plate 7.

[0035] Specifically, as shown in the figure, Figure 1 The opposite two sides of the air passing plate 6 are connected with two side plates, and the side plates are connected in a closed whole with the side walls of the flow equalizing plate 3, which surrounds the air inlet 2 and is connected to the wall surface of the air inlet 2 in the box body 1.

[0037] The working principle of the embodiment is as follows: when the air volume needs to be adjusted, the knob 13 is twisted to drive the screw rod 11 to rotate. Due to the limiting effect of the flow equalizing plate 3 on the air volume adjusting plate 7, the air volume adjusting plate 7 can only move axially along the screw rod 11, so as to adjust the position of the adjusting body 8 in the air passing hole 17 and change the gap size between the adjusting body 8 and the air passing hole 17, thereby achieving the effect of adjusting the air volume.

[0038] Embodiment 2

[0039] Specifically, as shown in the figure, Figure 4 The screw rod 11 is connected with a motor 12. The control system connected with the motor 12 adopts any existing technology that can control the start of the motor 12, and will not be described here. A connecting plate is arranged outside the box body 1 to fixedly connect the motor 12 to the box body 1. Its function is that, through the arrangement of the motor 12, the rotation of the screw rod 11 can be remotely controlled.

[0040] The working principle of the embodiment is as follows: when the air volume needs to be adjusted, the motor 12 is started to drive the screw rod 11 to rotate. Due to the limiting effect of the flow equalizing plate 3 on the air volume adjusting plate 7, the air volume adjusting plate 7 can only move axially along the screw rod 11, so as to adjust the position of the adjusting body 8 in the air passing hole 17 and change the gap size between the adjusting body 8 and the air passing hole 17, thereby achieving the effect of adjusting the air volume.

[0041] The remaining structure and working principle are the same as those of embodiment 1, and will not be described here.

[0042] The above is only a preferred embodiment of the present application, and does not limit the present application in any form.
