[0001] This utility model belongs to the field of medical air purification equipment technology, specifically referring to a high-efficiency filter for clean operating rooms. Background Technology

[0002] As a core area for hospital infection control, the air cleanliness of clean operating rooms directly affects surgical success rates and postoperative recovery outcomes for patients. Clean operating rooms require high-efficiency particulate filters to effectively filter airborne particles and retain bacteria, viruses, and other microorganisms.

[0003] Existing HEPA filters for clean operating rooms mostly use bolt-fixed or clip-on connections, which has several drawbacks. First, installation and disassembly require tools such as wrenches and screwdrivers for point-by-point operation, making it difficult for a single person to operate and time-consuming, affecting the continuous use of the operating room and increasing the pressure on surgical scheduling. Second, the installation positioning accuracy relies too heavily on manual operation, which can easily lead to misalignment and deviations, causing gaps between the filter and the mounting frame, resulting in air leakage, and consequently affecting the airflow balance and purification effect of the clean room. Utility Model Content

[0004] To address the aforementioned problems of inconvenient installation and disassembly, and poor positioning accuracy of existing high-efficiency filters for clean operating rooms, this invention provides a high-efficiency filter for clean operating rooms.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a high-efficiency filter for a clean operating room, including a support plate and a filter body, wherein an installation groove is provided in the middle of the support plate, the filter body is installed in the installation groove, and a first support is symmetrically fixed on one side bottom of the support plate, and a driving component is provided between the first supports;

[0006] A support box is fixed at the middle position of the bottom on the same side of the support plate. The driving assembly includes a vertically arranged connecting rod and two sets of horizontally arranged screws. The top end of the connecting rod extends into the support box and is fixed with a first straight bevel gear. The ends of the screws are rotatably mounted on the inner side wall of the corresponding first support through bearings. The opposite ends of the two sets of screws are respectively fixed with a second straight bevel gear. The second straight bevel gear meshes with the first straight bevel gear for transmission. Two sets of driving blocks are threadedly fitted on the two sets of screws. The bottom of the two sets of driving blocks is vertically fixed with an L-shaped clamping plate. The filter body is clamped and fixed between the L-shaped clamping plates.

[0007] As a preferred technical solution of this utility model, the support box is provided with vertical grooves symmetrically on both sides, and the two sets of screws are respectively arranged to pass through the vertical grooves on the corresponding sides.

[0008] As a preferred technical solution of this utility model, two sets of second supports are symmetrically fixed at the bottom of the other side of the support plate, and a guide slide rod parallel to the screw is fixed between the two sets of second supports. The far ends of the two sets of driving blocks are slidably sleeved on both ends of the guide slide rod.

[0009] As a preferred embodiment of this utility model, the filter body has horizontal support grooves symmetrically opened on both sides, and the end of the L-shaped clamp is inserted into the support groove.

[0010] As a preferred technical solution of this utility model, the two inner sidewalls of the mounting groove are symmetrically provided with insertion grooves, and the two sides of the filter body are symmetrically provided with insertion blocks. The insertion blocks are located on the upper side of the support groove and form an insertion fit with the insertion groove.

[0011] As a preferred embodiment of this utility model, the bottom end of the connecting rod extends to the outside of the support box and is fixed with a handle; multiple connecting blocks are evenly distributed circumferentially on the outer side of the support plate.

[0012] Compared with the prior art, the present invention achieves the following beneficial effects by adopting the above structure:

[0013] By using a combination of handle, first bevel gear, second bevel gear, drive assembly, L-shaped clamp, insertion slot, and insertion block, the filter body can be quickly disassembled and precisely positioned. Manually turning the handle drives the connecting rod to rotate, which in turn moves the drive block along the screw axis, allowing the L-shaped clamp to simultaneously clamp or release the filter body. Without the need for additional tools, a single person can quickly complete the filter replacement operation, significantly improving the maintenance efficiency of filters in clean operating rooms.

The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-4As shown, the high-efficiency filter for a clean operating room provided by this utility model includes a support plate 1 and a filter body 2. A mounting groove 3 is provided in the middle of the support plate 1, and the filter body 2 is installed in the mounting groove 3. First supports 4 are symmetrically fixed to the bottom of one side of the support plate 1, and a driving assembly 5 is arranged between the first supports 4. A support box 6 is fixed to the middle position of the bottom of the same side of the support plate 1. The driving assembly 5 includes a vertically arranged connecting rod 7 and two sets of horizontally arranged screws 8. The top end of the connecting rod 7 extends into the support box 6 and is fixed with a first straight bevel gear 9. The ends of the screws 8 are rotatably mounted on the inner sidewalls of the corresponding first supports 4 via bearings. Second straight bevel gears 10 are fixedly installed at the opposite ends of the two sets of screws 8. The second straight bevel gears 10 and the first... The filter body 2 is clamped and fixed between the L-shaped clamps 12 by the meshing transmission of the straight bevel gear 9. The two sets of screws 8 are respectively threaded and fitted with two sets of drive blocks 11. The bottom of the two sets of drive blocks 11 is vertically fixed with L-shaped clamps 12. The connecting rod 7 rotates and drives the first straight bevel gear 9 to rotate, meshing with the second straight bevel gear 10 to realize the conversion of vertical motion to horizontal motion, driving the two sets of screws 8 to rotate synchronously. The drive blocks 11 on the screws 8 convert the rotational motion into linear motion through the threaded engagement, realizing the synchronous movement of the L-shaped clamps 12 in opposite directions, thereby clamping or releasing the filter body 2. The support box 6 has vertical slots 13 symmetrically opened on both sides. The two sets of screws 8 are respectively set through the vertical slots 13 on the corresponding sides, and the vertical slots 13 provide space for the movement of the screws 8.

[0023] like Figure 2 and 3 As shown, two sets of second supports 14 are symmetrically fixed at the bottom of the other side of the support plate 1. A guide slide rod 15 parallel to the screw 8 is fixed between the two sets of second supports 14. The distal ends of the two sets of driving blocks 11 are slidably sleeved on both ends of the guide slide rod 15. The guide slide rod 15 can provide guidance and limit for the driving blocks 11, and prevent the driving blocks 11 from rotating with the screw 8.

[0024] like Figure 2-4 As shown, the filter body 2 has horizontal support grooves 16 symmetrically opened on both sides. The end of the L-shaped clamp 12 is inserted into the support groove 16, forming a mechanical interlock structure, so as to realize the precise positioning of the filter body 2 in the horizontal direction.

[0025] like Figure 3 and 4 As shown, the two inner sidewalls of the mounting groove 3 are symmetrically provided with insertion grooves 17, and the two sides of the filter body 2 are symmetrically provided with insertion blocks 18. The insertion blocks 18 are located on the upper side of the support groove 16 and form an insertion fit with the insertion grooves 17. During the installation process, the fit between the insertion blocks 18 and the insertion grooves 17 provides an insertion guide for the filter, ensuring that the L-shaped clamp 12 can be accurately aligned with the support groove 16.

[0026] like Figure 1-3 As shown, the bottom end of the connecting rod 7 extends to the outside of the support box 6 and is fixed with a rotating handle 19. Manually rotating the handle 19 can drive the first bevel gear 9 to rotate through the connecting rod 7, converting the vertical rotational force into the horizontal driving force. Multiple connecting blocks 20 are evenly distributed on the outer circumference of the support plate 1 for fixed connection with the ceiling structure of the operating room.

[0027] In practical use, first insert the filter body 2 into the mounting groove 3 in the middle of the support plate 1 through the adapter of the plug block 18 and the mounting groove 3. Then, manually turn the handle 19 to drive the connecting rod 7 and the first straight bevel gear 9 at the top to rotate. Through the meshing transmission of the first straight bevel gear 9 and the second straight bevel gear 10, the two sets of screws 8 rotate synchronously in opposite directions. Under the action of the thread, the drive block 11 on the screw 8 moves linearly along the screw 8 and the guide slide rod 15, driving the L-shaped clamp 12 to move inward until the end of the L-shaped clamp 12 is inserted into the support groove 16, thus completing the stable clamping and fixing of the filter body 2. When it is necessary to disassemble and replace the filter body 2, turn the handle 19 in the opposite direction to loosen the L-shaped clamp 12, and the filter body 2 can be easily removed.

[0028] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
