DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings:

[0022] Embodiment 1:

[0023] See attached Figure 1-6: In this embodiment, a high-efficiency air supply ceiling with a flow-equalizing membrane dedicated to an operating room includes an air supply ceiling body 1 and an air inlet pipe 2. Two air inlet pipes 2 are fixedly connected to the outer wall of the air supply ceiling body 1. A filtering mechanism 3 is arranged inside the air inlet pipe 2. The filtering mechanism 3 filters dust and impurities. A positioning mechanism 4 is arranged below the air supply ceiling body 1. The positioning mechanism 4 realizes the positioning of the flow-equalizing membrane body 7. A groove 5 is fixedly connected inside the air supply ceiling body 1.

[0024] The internal gap of the groove 5 is matched with a bracket 6, the bracket 6 and the groove 5 can be separated, the interior of the bracket 6 is fixedly connected to a flow equalizing membrane body 7, the interior of the air supply ceiling body 1 is provided with a hollow groove 8, the hollow groove 8 is connected to the groove 5, the interior of the air supply ceiling body 1 is provided with two air supply pipes 9, the two air supply pipes 9 are connected to the hollow groove 8, the air supply pipe 9 is connected to the air inlet pipe 2, and a frame 10 is fixedly connected below the air inlet pipe 2, the frame 10 is connected to the air inlet pipe 2 through a pipe 11, and the pipe 11 is arranged on the left side of the lower end of the filter 305.

[0025] The filtering mechanism 3 includes a support rod 301, a rotating rod 302, an impeller 303, a brush 304 and a filter screen 305. The support rod 301 is fixedly connected to the inner wall of the air inlet pipe 2. The support rod 301 is rotatably connected to the outer wall of the rotating rod 302 through a bearing. The support rod 301 supports the rotating rod 302. The width of the support rod 301 is small and does not affect the passage of wind. One end of the rotating rod 302 is fixedly connected to the impeller 303, which drives the rotating rod 302 to rotate. The other end of the rotating rod 302 is fixedly connected to the brush plate 304, which drives the brush plate 304 to rotate. The brush plate 304 fits the outer wall of the filter screen 305. The brush plate 304 cleans the dust and impurities on the surface of the filter screen 305 when rotating. The filter screen 305 is fixedly connected to the inner wall of the air inlet pipe 2 to prevent dust and impurities from passing through the filter screen 305.

[0026] The wind entering the air inlet duct 2 contacts the filter 305, and the filter 305 filters the dust and impurities in the incoming wind. When the wind enters the air inlet duct 2, it drives the impeller 303 to rotate, and the impeller 303 drives the rotating rod 302 to rotate, and the rotating rod 302 drives the brush plate 304 to rotate, and the brush plate 304 cleans the impurities and dust attached to the surface of the filter 305.

[0027] The positioning mechanism 4 includes a sleeve 401, a slide bar 402, a spring 403, a pressure plate 404 and a handle 405. The sleeve 401 is fixed to the lower surface of the air supply ceiling body 1. Four sleeves 401 are provided. The interior of the sleeve 401 is slidably connected to the slide bar 402. The slide bar 402 slides inside the sleeve 401. The interior of the sleeve 401 is provided with a spring 403. The model of the spring 403 is selected according to the use requirements to meet the work needs.

[0028] The two ends of the spring 403 are respectively fixedly connected to the sleeve 401 and the slide bar 402. The spring 403 can drive the pressure plate 404 to move under the action of elasticity. The ends of the front and rear slide bars 402 are fixedly connected to the pressure plate 404. The front and rear slide bars 402 move together with the pressure plate 404. The outer wall of the pressure plate 404 is fixedly connected with a handle 405. The handle 405 drives the pressure plate 404 to move. The pressure plate 404 fits the outer wall of the bracket 6. The pressure plates 404 on both sides clamp and fix the bracket 6 inside the groove 5.

[0029] When the flow equalizing membrane body 7 needs to be replaced, the handles 405 on both sides are pulled down, and the handles 405 drive the pressure plate 404 to move, and the pressure plate 404 drives the sliding rod 402 to move. The sliding rod 402 slides inside the sleeve 401 and compresses the spring 403. At this time, the two pressure plates 404 are separated from the bracket 6, and the bracket 6 is taken out from the groove 5, and then the flow equalizing membrane body 7 is taken out, and the flow equalizing membrane body 7 and the bracket 6 are replaced, and the new bracket 6 is placed inside the groove 5, and the handle 405 is released. The spring 403 drives the sliding rod 402 to slide in the opposite direction under the elastic action, and the sliding rod 402 drives the pressure plate 404 to move. The pressure plates 404 on both sides are fitted with the outer wall of the bracket 6, and the bracket 6 is clamped and fixed inside the groove 5, completing the replacement of the flow equalizing membrane body 7. The operation is relatively simple, and it is easy to realize the replacement of the flow equalizing membrane body 7.

[0030] Working principle:

[0031] When the special flow-equalizing membrane high-efficiency air supply ceiling for operating rooms is used in the operating room, first, the air supply ceiling body 1 is placed on the corresponding bracket of the operating room, and other equipment let the external air enter through the two air inlet pipes 2, along the air supply pipe 9 into the inside of the hollow groove 8, and finally reach the flow-equalizing membrane body 7 and pass through the flow-equalizing membrane body 7. The flow-equalizing membrane body 7 evenly distributes the air to the inside of the operating room. The working principles of the air supply ceiling body 1 and the flow-equalizing membrane body 7 are existing technologies and will not be described in detail.

[0032] Filtering stage:

[0033] The wind entering the air inlet pipe 2 contacts the filter 305, and the filter 305 filters the dust and impurities in the incoming wind. When the wind enters the air inlet pipe 2, the impeller 303 is blown to rotate, and the impeller 303 drives the rotating rod 302 to rotate, and the rotating rod 302 drives the brush plate 304 to rotate, and the brush plate 304 cleans the impurities and dust attached to the surface of the filter 305. When the wind entering the air inlet pipe 2 weakens or stops, the cleaned dust and impurities fall through the pipe 11 into the interior of the frame 10 under the action of gravity, and the brush plate 304 cleans the filter 305, and the filter 305 prevents dust and impurities from passing through, so that the dust and impurities will not stick to the flow equalizing membrane body 7 and affect the air supply effect of the air supply ceiling body, thereby achieving efficient air supply.

[0034] Phase of replacing the flow equalizing membrane body:

[0035] When the flow equalizing membrane body 7 needs to be replaced, the handles 405 on both sides are pulled down, and the handles 405 drive the pressure plate 404 to move, and the pressure plate 404 drives the sliding rod 402 to move. The sliding rod 402 slides inside the sleeve 401 and compresses the spring 403. At this time, the two pressure plates 404 are separated from the bracket 6, and the bracket 6 is taken out from the groove 5, and then the flow equalizing membrane body 7 is taken out, and the flow equalizing membrane body 7 and the bracket 6 are replaced, and the new bracket 6 is placed inside the groove 5, and the handle 405 is released. The spring 403 drives the sliding rod 402 to slide in the opposite direction under the elastic action, and the sliding rod 402 drives the pressure plate 404 to move. The pressure plates 404 on both sides are fitted with the outer wall of the bracket 6, and the bracket 6 is clamped and fixed inside the groove 5, completing the replacement of the flow equalizing membrane body 7. The operation is relatively simple, and it is easy to realize the replacement of the flow equalizing membrane body 7.
