Description

Technical Field

[0001] The invention relates to the technical field of air treatment equipment, in particular to a silent self-circulating clean operating room. Background Art

[0002] The operating room is a key place for surgical operations, and a sterile, clean and safe working environment must be maintained. Traditional operating rooms usually use laminar flow ventilation and other designs to reduce the number of pollutants and microorganisms in the air, but the design and maintenance of laminar flow ventilation systems are relatively complex, involving multiple devices and monitoring systems, and require regular inspection and maintenance by professionals, which increases operating costs.

[0003] The document entitled “A Silent Self-Circulating Clean Operating Room” (document number CN210399305U) discloses a technical solution for a clean operating room, which coordinates the ratio of fresh air and circulating air in the air intake main pipe and makes the air intake in the operating room uniform by arranging an air supply device, an air filter, a first fan, a second fan, a third fan, a filtering device and a fourth fan, thereby avoiding excessive local air flow rate, and utilizing the recycled gas to pass through the filtering device to become circulating gas, which still meets the cleanliness standard after mixing with the fresh gas, and is discharged to the operating room again for utilization; however, the above document does not introduce in detail how to filter the gas, and the existing air filtering equipment is prone to filter blockage when filtering the air for a long time, resulting in reduced gas filtration efficiency, resulting in the inability to timely input fresh air into the operating room, and the air circulation speed in the operating room is reduced. Therefore, the blocked filter also needs to be shut down and replaced in time, thereby causing the air circulation system of the operating room to stop operating. Summary of the invention

[0006] As a further improvement of the present invention: an air intake blade is arranged at one end of the rotating shaft close to the filter frame, and the rod is fixed on the surface of the air intake blade.

[0007] As a further improvement of the present invention: a guide rod is fixed to the rear side of the second impact plate, and the free end of the guide rod is located on the circular motion trajectory of the rod.

[0008] As a further improvement of the present invention: the filter frame is composed of a circular ring-shaped frame body and a disc-shaped filter screen, the circular core of the frame body coincides with the axial core of the rotating shaft; the right side frame surface of the frame body includes a friction surface that forms a sliding fit with the rod, and the friction surface occupies half of the right side frame surface of the frame body.

[0009] As a further improvement of the present invention: the frame and the filter are both made of plastic material, and a fur section is provided at the end of the rod away from the air intake blades; an alumina ceramic plate is fixed on the inner wall of the opening side of the air inlet box, and an installation groove for installing the filter frame is provided on the surface of the alumina ceramic plate.

[0010] As a further improvement of the present invention: an ash receiving box with an open top is installed at the bottom of the open side of the air inlet box, and the ash receiving box is located directly below the filter frame.

[0011] As a further improvement of the present invention: an activated carbon filter layer is arranged at intervals inside the buffer box, a transparent buffer block is arranged at intervals above the activated carbon filter layer, a cavity is arranged inside the transparent buffer block, and a sterilization lamp is installed in the cavity; the transparent buffer blocks are arranged at an angle at intervals.

[0012] As a further improvement of the present invention: a sound-absorbing layer is arranged on the inner wall of the air outlet disc, and air outlet nozzles are evenly arranged on the bottom of the air outlet disc; and a sound-insulating layer is arranged on the surface of the outer wall.

[0013] As a further improvement of the present invention: a second fan is installed outside the outer wall, an air inlet end of the second fan is connected to the interior of the operating room, and an exhaust end of the second fan is connected to the buffer box.

[0014] The present invention is beneficial in that: 1. In the present invention, the gas outside the operating room enters the air inlet box from the open side of the air inlet box.

[0015] 2. In the present invention, the air intake fan blades are driven to rotate by the rotating shaft. On the one hand, the speed of gas flowing from the filter frame into the air inlet box is accelerated to ensure that the gas quickly enters the air inlet box to filter the dust. On the other hand, the rotating air intake fan blades drive the rod to rotate together, so that the rod can intermittently squeeze the second impact plate, thereby achieving impact on the filter frame, causing dust to fall from the filter frame, ensuring normal filtering of dust by the filter frame.

[0016] 3. In the present invention, when the rotating shaft drives the air intake fan blades and the rod to rotate, the fur section at the end of the rod rubs against the friction surface on the right side of the frame, so that the frame generates negative charge. Due to the tip effect, charge accumulation will appear on the edge of the frame, so that the dust with positive charge in the surrounding air is adsorbed to the edge of the frame, thereby reducing the amount of dust on the surface of the filter screen and reducing the probability of clogging of the filter screen, thereby improving the filtering effect of the gas; when the rod is displaced to the guide rod and the second impact plate is pressed downward to contact the bottom of the air inlet box, the negative charge on the filter frame will be transmitted to the air inlet box through the I-shaped plate and finally enter the ground, so that the adsorption force of the frame on the dust disappears, and at this time the first impact plate just hits the frame, causing the filter frame to vibrate, which is beneficial to shake off the dust on the frame and allow it to enter the dust receiving box.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 6As shown, a silent self-circulating clean operating room includes an outer wall 10 constituting the operating room and an air supply mechanism 20 arranged on the outer wall 10, the air supply mechanism 20 includes an air inlet box 21 and a buffer box 22 arranged on one side of the outer wall 10, the buffer box 22 is fixed on the top of the air inlet box 21, and the air inlet box 21 is connected to the inside of the buffer box 22, a first fan 23 is installed on the outer wall 10 at the top of the operating room, one end of the first fan 23 is connected to the buffer box 22, and the other end is connected to the air outlet disk 24 inside the operating room; the side of the air inlet box 21 away from the outer wall 10 is in an open state, and the inner wall of the open side of the air inlet box 21 is fixed with a filter frame 25 for filtering air, and an I-shaped plate 26 is vertically penetrated and slidably arranged on the bottom frame of the filter frame 25, and the I-shaped plate 26 includes a through A guide rod 261 is slidably arranged on the bottom frame of the filter frame 25, the top end of the guide rod 261 is fixedly connected to a first impact plate 262, the bottom end of the guide rod 261 is fixedly connected to a second impact plate 263, the right side of the second impact plate 263 extends out of the right side frame surface of the filter frame 25, the bottom of the first impact plate 262 is fixedly provided with a first spring 264, and the bottom end of the first spring 264 is fixed to the bottom frame of the filter frame 25; a rotating shaft 271 is rotatably arranged inside the air inlet box 21, and a rod 273 is arranged on the rotating shaft 271, the other end of the rod 273 abuts against the right side of the frame of the filter frame 25 and forms a sliding fit with the frame of the filter frame 25 in the circumferential direction, and the rod 273 rotates with the rotating shaft 271 and intermittently squeezes the second impact plate 263; wherein the first impact plate 262 is in a downwardly curved arc shape as a whole; When the above scheme is implemented, the first fan 23 is started, and the air outside the operating room enters the air inlet box 21 from the open side of the air inlet box 21. In this process, the dust in the air is filtered by the filter frame 25, and then the dust-free gas enters the buffer box 22 to reduce the flow speed, and then flows into the interior of the operating room from the air outlet plate 24; when the filter frame 25 is clogged with dust, the drive mechanism drives the shaft 271 to rotate, and the shaft 271 drives the rod 273 to rotate together, so that the rod 273 can intermittently squeeze the second impact plate 263, and the second impact plate 263 moves downward, so that the first spring 264 is compressed, and at the same time the first impact plate 262 hits the bottom inner frame surface of the filter frame 25, so that the The filter frame 25 vibrates to shake off the dust from the filter frame 25. When the rod 273 leaves the second impact plate 263, due to the elastic force of the first spring 264, the second impact plate 263 moves upward and hits the bottom outer frame surface of the filter frame 25, so that the filter frame 25 vibrates again to shake off the dust from the filter frame 25. In the above, before the rod 273 squeezes the second impact plate 263, the top plate surface of the second impact plate 263 is in contact with the bottom outer frame surface of the filter frame 25, wherein the right side surface of the second impact plate 263 extends out of the right side frame surface of the filter frame 25, which can ensure that the driving mechanism can squeeze the second impact plate 263 through the plate surface above the right side of the second impact plate 263.

[0022] like Figure 3 , 4 As shown, further, an air intake fan blade 272 is provided at one end of the rotating shaft 271 close to the filter frame 25, and the rod 273 is fixed on the surface of the air intake fan blade 272; the rotating shaft 271 drives the air intake fan blade 272 to rotate, on the one hand, the speed at which the gas flows from the filter frame 25 into the air inlet box 21 is accelerated to ensure that the gas quickly enters the air inlet box 21 to filter the dust; on the other hand, the rotating air intake fan blade 272 drives the rod 273 to rotate together, so that the rod 273 can intermittently squeeze the second impact plate 263, thereby achieving an impact on the filter frame 25, causing the dust to fall from the filter frame 25, and ensuring the normal filtering of the dust by the filter frame 25.

[0023] In order to make the collision between the second impact plate 263 and the filter frame 25 stronger, the length of the second impact plate 263 should be reduced, that is, the extrusion trajectory of the rod 273 and the second impact plate 263 should be shortened. The best solution is that the rod 273 leaves the surface of the second impact plate 263 when the rod 273 squeezes the second impact plate 263 to the lowest position.

[0024] like Figure 5As shown, a guide rod 265 is fixed to the rear side of the second impact plate 263, and the free end 2651 on the guide rod 265 is located on the circular motion trajectory of the rod 273; when the rod 273 rotates and reaches the free end 2651 on the guide rod 265, the rod 273 will drive the second impact plate 263 to move downward, so that the first impact plate 262 impacts the filter frame 25.

[0025] like Figure 4 , 5 As shown, further, the filter frame 25 is composed of a ring-shaped frame body 251 and a disc-shaped filter screen 252, and the circular core of the frame body 251 coincides with the axial core of the rotating shaft 271; the right side frame surface of the frame body 251 includes a friction surface 2511 that forms a sliding fit with the rod 273, and the friction surface 2511 occupies half of the right side frame surface of the frame body 251; the frame body 251 and the filter screen 252 are both made of plastic material, and a fur segment 2731 is provided at one end of the rod 273 away from the air intake fan blade 272; An alumina ceramic plate 28 is fixed on the inner wall of the opening side of the air inlet box 21, and a mounting groove for mounting the filter frame 25 is provided on the surface of the alumina ceramic plate 28; a ash receiving box 29 with a top opening is installed at the bottom of the opening side of the air inlet box 21, and the ash receiving box 29 is located directly below the filter frame 25; when the rotating shaft 271 drives the air inlet blades 272 and the rod 273 to rotate, the fur section 2731 at the end of the rod 273 rubs against the friction surface 2511 on the right side of the frame 251, so that the surface of the frame 251 Negative charges are generated. Due to the tip effect, charges will accumulate on the edge of the frame 251, so that the dust with positive charges in the surrounding air is adsorbed to the edge of the frame 251, thereby reducing the amount of dust on the surface of the filter 252 and reducing the probability of clogging of the filter 252, thereby improving the filtering effect of the gas; and the alumina ceramic plate 28 has a very high resistance, which can inhibit the negative charges generated by friction from being transferred to the alumina ceramic plate 28, so that the negative charges on the frame 251 will not be transferred; when the rod When 273 moves to the guide rod 265 and squeezes the second impact plate 263 downward to contact the bottom of the air inlet box 21, the negative charge on the filter frame 25 will be transferred to the air inlet box 21 through the I-shaped plate 26 and finally enter the ground, so that the adsorption force of the frame 251 on the dust disappears, which facilitates the falling of the dust. At this time, the first impact plate 262 just hits the frame 251, causing the filter frame 25 to vibrate, which is beneficial to shake off the dust on the frame 251 and make it enter the dust box 29 to realize the collection of dust.

[0026] In the above, when the air intake blades 272 rotate, the air flow around the filter frame 25 is accelerated, making the filter frame 25 and the air around it drier, thereby further ensuring that negative charges are not transferred from the alumina ceramic plate 28 to the air intake box 21.

[0027] like Figure 3 , 6 As shown, as a preferred embodiment of the present invention, the buffer box 22 is provided with an activated carbon filter layer 221 at intervals inside, and a transparent buffer block 222 is arranged at intervals above the activated carbon filter layer 221, and a cavity is provided inside the transparent buffer block 222, and a sterilization lamp 223 is installed in the cavity; the transparent buffer blocks 222 are arranged at an angle and intervals; the activated carbon filter layer 221 is used to filter odors in the air, and preferably, at least three layers of the activated carbon filter layer 221 are provided; two adjacent transparent buffer blocks 222 are respectively arranged on the inner walls on both sides of the buffer box 22 opposite to each other, so that the gas flow path entering the buffer box 22 is in a zigzag shape to reduce the flow speed of the gas. On the one hand, it reduces the noise caused by the gas flow, and on the other hand, the gas with a low flow speed can be fully irradiated by the light of the sterilization lamp 223, thereby improving the sterilization effect on the gas.

[0028] like Figure 2 As shown, in order to reduce the sound in the operating room, the inner wall of the air outlet plate 24 is provided with a sound-absorbing layer, and the bottom of the air outlet plate 24 is evenly provided with air outlet nozzles 241; the surface of the outer wall 10 is provided with a sound insulation layer; by making the gas flow into the operating room evenly, excessive local flow velocity is avoided; the sound insulation layer can isolate the sound outside the operating room, especially the noise generated when the first fan 23 and the second fan 30 are working; it should be noted that the first fan 23 and the second fan 30 can adopt low-noise fans.

[0029] like Figure 1 , 2 As shown, as a preferred embodiment of the present invention, a second fan 30 is installed on the outside of the outer wall 10, and the air inlet end of the second fan 30 is connected to the interior of the operating room, and the exhaust end of the second fan 30 is connected to the buffer box 22; when the air pressure inside the operating room is too high, the second fan 30 can be started to extract the gas inside the operating room and send it into the buffer box 22, and then mix it with the gas entering the air inlet box 21, and then input it into the operating room again, so as to realize the recycling of the gas inside the operating room.
