Description

Technical Field

[0001] This utility model relates to the field of air purification technology, and in particular to an air purification system for operating rooms. Background Technology

[0002] The operating room is a place for providing surgical and emergency care to patients and is an important technical department of the hospital. The operating room should be connected to other surgical departments and also be adjacent to the blood bank, intensive care unit, and anesthesia recovery room. It is crucial to manage the four routes of surgical site infection effectively: the air in the operating room; surgical supplies; the fingers of doctors and nurses; and the patient's skin, to prevent infection and ensure surgical success.

[0003] Announcement No. CN219346700U proposes a multi-stage air purification system for clean operating rooms. The filter plate can slide from the top or side wall of the mounting block into the embedded placement groove. After the mounting block is removed from the mounting groove, the filter plate is not easy to fall off the mounting block from either of these directions, that is, the filter plate is not easy to fall off the wall. Through the cooperation of the sliding gears at both ends of the linkage rod and the sliding racks at both ends of the sliding frame, the sliding distance of both ends of the sliding frame in the sliding groove is the same, which improves the stability of the sliding frame in the sliding groove, thereby improving the reliability of the filter plate sliding driven by the sliding frame.

[0004] However, during the implementation of this device, the flip plate is rotated out of the fitting slot via the retrieval slot, and the control button is pressed towards the control slot. When the control button slides, it drives the sliding gear to rotate. Under the action of gear transmission, the sliding frame slides out of the mounting slot, allowing the filter plate to be slid out from the side of the mounting block. During removal, the device does not obstruct the ventilation duct, and the filter plate vibrates when being pulled out. This causes the dust filtered on the filter plate to vibrate, resulting in dust falling off the filter plate and drifting into the ventilation duct. Consequently, the dust enters the operating room through the ventilation duct, contaminating the interior of the operating room and affecting subsequent surgeries. It can also cause infection of the patient's wounds. Therefore, an air purification system for the operating room is proposed to solve the above problems. Utility Model Content

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Please see Figure 1-6 This utility model provides a technical solution: an air purification system for an operating room, including a ventilation duct 1, an installation groove 5 inside the ventilation duct 1, an installation frame 2 slidably connected to the inner wall of the installation groove 5, a placement groove 14 inside the installation frame 2, a filter screen 4 slidably connected to the inner wall of the placement groove 14, the filter screen 4 filters the incoming air, a fixing shell 8 is fixedly connected inside the ventilation duct 1, a receiving cavity 16 is opened inside the fixing shell 8, a baffle 9 is slidably connected to the inner wall of the receiving cavity 16, a driving groove 10 is opened on the side of the baffle 9 near the installation frame 2, the bottom surface of the inner wall of the driving groove 10 is inclined, and the baffle 9 is slidably connected to the inner wall of the ventilation duct 1, a driving rod 12 is fixedly connected to the side of the installation frame 2 near the inside of the ventilation duct 1, the driving rod 12 is parallel to the position of the driving groove 10, and a ball is embedded in the end of the driving rod 12 away from the installation frame 2, the ball is used to reduce the friction of the driving rod 12.

[0026] A second spring 17 is fixedly connected to the inner wall of the storage cavity 16. The end of the second spring 17 away from the fixed shell 8 is fixedly connected to the baffle 9. Thus, the sliding reset of the baffle 9 is controlled by the setting of the second spring 17.

[0027] The mounting frame 2 is internally connected to a bolt 3. The inner wall of the mounting groove 5 is provided with a fixing groove 7 and a threaded groove. When the mounting frame 2 is inserted into the mounting groove 5, the fixing groove 7 corresponds to the bolt 3, and the bolt 3 is rotated so that it is inserted into the fixing groove 7, thereby fixing the ventilation duct 1 and the mounting frame 2.

[0028] The inner wall of the mounting groove 5 is provided with a support groove 6. A support rod 11 is fixedly connected to the side of the mounting frame 2 near the ventilation duct 1. The support rod 11 corresponds to the position of the support groove 6. When the mounting frame 2 is inserted into the mounting groove 5, the support rod 11 is inserted into the support groove 6. Thus, the sliding of the mounting frame 2 is supported and guided by the support rod 11.

[0029] A limiting rod 13 is slidably connected to the side of the mounting frame 2 near the inside of the ventilation duct 1. A limiting hole 18 is opened on the surface of the filter screen 4, which corresponds to the limiting rod 13. A first spring 15 is movably sleeved on the surface of the limiting rod 13. The two ends of the first spring 15 are fixedly connected to the mounting frame 2 and the limiting rod 13 respectively. The sliding reset of the limiting rod 13 is controlled by the setting of the first spring 15.

[0030] Working principle: When installing the filter screen 4, insert the filter screen 4 into the placement groove 14, then align the support rod 11 with the support groove 6, and press the mounting frame 2 so that the mounting frame 2 is inserted into the mounting groove 5. As the mounting frame 2 is inserted, the surface of the drive rod 12 inserts into the drive groove 10, and the surface of the drive rod 12 presses against the inner wall of the drive groove 10. Under the setting of the inclined surface of the drive groove 10 and the ball bearings, the baffle 9 is pushed into the receiving cavity 16. The movement of the baffle 9 causes the second spring 17 to deform. At this time, the baffle 9 no longer seals the ventilation duct 1. Then, the bolt 3 is rotated, causing the bolt 3 to... The mounting frame 2 is locked inside the fixing groove 7. When the filter screen 4 needs to be removed, the bolt 3 is rotated, and the bolt 3 separates from the fixing groove 7. Then the mounting frame 2 is pulled, and the mounting frame 2 slides out from inside the ventilation duct 1. The mounting frame 2 drives the support rod 11 and the drive rod 12 to slide. The support rod 11 slides to support it, and the drive rod 12 slides to separate from the baffle 9. Then the drive rod 12 no longer blocks the sliding of the baffle 9. Then, under the elastic force of the second spring 17, the baffle 9 slides out to close the ventilation duct 1, thereby preventing the dust from shaking and drifting into the interior of the ventilation duct 1 when the filter screen 4 is removed.

[0031] When the mounting frame 2 is inserted into the mounting groove 5, the limiting rod 13 comes into contact with the inner wall of the mounting groove 5, and then the limiting rod 13 moves into the mounting frame 2. The movement of the limiting rod 13 causes the first spring 15 to deform, and then the limiting rod 13 moves into the limiting hole 18 to lock the filter screen 4, further fixing the filter screen 4. When the filter screen 4 is removed, the mounting frame 2 separates from the mounting groove 5, and then the mounting groove 5 no longer contacts the limiting rod 13. Then, under the elastic force of the first spring 15, the limiting rod 13 slides out from the limiting hole 18, and no longer obstructs the removal of the filter screen 4.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
