[0018] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] Figure 1 and Figure 2An adjustable air diversion and purification device for use in a clean operating room is shown, comprising a T-shaped top diversion pipe 1 installed at the connecting end of the top ventilation pipe of the clean operating room, a spherical adjustment chamber is arranged in the middle position of the internal chamber of the top diversion pipe 1, an electrically-controlled spherical internal adjustment seat 2 is installed inside the spherical adjustment chamber, a detachable air filter element 3 is installed inside the electrically-controlled spherical internal adjustment seat 2, and a bottom inlet 5 with a centrifugal diversion fan 4 installed inside is opened at the lower end of the electrically-controlled spherical internal adjustment seat 2.

[0021] In order to cooperate with the adjustment, the electrically controlled spherical internal adjustment seat 2 includes a spherical assembly seat 21 movably assembled inside the spherical adjustment chamber, an adjustment motor 22 fixed on the outer surface of the top guide tube 1, and an internal adjustment gear 23 for transmission connection between the spherical assembly seat 21 and the adjustment motor 22.

[0022] The adjusting motor 22 is a prior art, and is used to drive the internal adjusting gear 23 to rotate, thereby driving the spherical assembly seat 21 to rotate and adjust.

[0023] In order to facilitate loading and unloading and air guiding, an annular loading and unloading groove 6 for installing the detachable air filter element 3 is provided at the upper end of the spherical assembly seat 21 , and lateral connecting ports 7 are provided on the inner walls on both sides of the annular loading and unloading groove 6 .

[0024] In order to cooperate with the transmission adjustment, an arc-shaped driving tooth groove 24 meshing with the internal adjustment gear 23 is provided on the outer arc surface of the spherical assembly seat 21.

[0025] The internal adjustment gear 23 is driven to rotate by the adjustment motor 22, thereby driving the spherical assembly seat 21 to adjust the angle inside the spherical adjustment chamber. When the bottom inlet 5 is set horizontally, air is drawn into the bottom inlet 5 through the bottom inlet 5, and then flows outward, passes through the detachable air filter 3, and is discharged into the room from the bottom of the top guide pipe 1, forming a positive pressure; and when the bottom inlet 5 opening is downwardly aligned with the bottom opening of the top guide pipe 1, air is drawn into the bottom inlet 5 through the bottom inlet 5, and then flows to both sides or one side of the top guide pipe 1, and is drawn to the outside, thereby forming a negative pressure; when the bottom inlet 5 opening is upwardly busy, people can open the sealing cover plate on the annular loading and unloading groove 6, so as to replace the detachable air filter 3 from the bottom.

[0026] In order to cooperate with the internal drive, the centrifugal guide fan 4 includes an embedded drive motor 41 fixed on the inner plane of the bottom inlet 5, a centrifugal drive barrel frame 42 axially installed on the outer drive shaft of the embedded drive motor 41, and a centrifugal guide blade 43 fixed inside the centrifugal drive barrel frame 42.

[0027] A blind hole for fixing the embedded drive motor 41 is provided on the inner plane of the bottom inlet 5, which can make full use of the internal space of the spherical assembly seat 21 and increase the area of ​​the centrifugal guide blades 43, thereby increasing the internal flux.

[0028] In order to monitor the air quality at the air inlet, a laser sensor module 8 for detecting air quality is fixedly mounted on the inner side of the bottom inlet 5 .

[0029] The laser sensor module 8 is a prior art, and has the same principle as the air quality module on the air purifier on the market. It monitors the air quality at the air inlet position and adjusts the speed of the embedded drive motor 41 according to the air quality.
