This embodiment of the present invention can solve the above problems. The specific implementation method is as follows. When purifying harmful smoke, the collection bin 131 is driven to rotate by the motor 7. Since the bottom of the filter element 8 is sleeved on the surface of the collection bin 131, and the filter element 8 is rotatably connected to the surface of the collection bin 131, when the electric telescopic rod 124 rotates, the scraper B129 cleans the inner wall of the filter element 8. At this time, the protruding end of the electric telescopic rod 124 will extend upward, so that the insertion table 127 moves upward, and then the insertion block 128 is squeezed, and the insertion block 128 When squeezed, the alcohol inside the liquid storage tank 11 will be transported to the water pipe 10, and then the alcohol will be sprayed onto the inner wall surface of the air intake pipe 3 through the spray head 121, and the inner wall of the air intake pipe 3 will be cleaned by the scraper A122, and the harmful substances after the inner wall of the filter element 8 is cleaned by the scraper B129 will fall into the collecting table 132 through the surface gap of the collecting bin 131, and then the electric telescopic rod 124 will be driven to rotate by the motor 7 again. Since the base 134 is continuously limited by the limiting ring 135, the collecting table 132 will rotate inside the collecting bin 131, and after the motor 7 drives the electric telescopic rod 124 to rotate an appropriate angle, the groove of the collecting table 132 can be closed.

The establishment of three groups of scrapers A122 can improve the cleaning effect of the inner wall of the intake pipe 3, and the arc-shaped design of the scrapers A122 can better allow harmful impurities to fall after cleaning.

[0023] As an embodiment of the present invention, the number of scrapers B129 is three groups, and they are distributed in a circular shape on the surface of the inserting platform 127. The extension of the protruding end of the electric telescopic rod 124 can drive the insert block 128 to squeeze the piston rod 123, thereby disinfecting the inner wall of the air intake pipe 3.

[0024] As an embodiment of the present invention, the internal grooves of the plug block 128 and the plug platform 127 are both hexagonal prisms, and the bottom end of the plug block 128 and the top end of the plug platform 127 are both chamfered. The establishment of the hexagonal prism can enable the plug platform 127 to drive the plug block 128 to rotate, and the chamfers at the bottom of the plug block 128 and the top end of the plug platform 127 can make it more convenient to install.

[0025] As an embodiment of the present invention, the impurity collection mechanism 13 includes a collecting bin 131 sleeved on the surface of the electric telescopic rod 124, a collecting platform 132 is sleeved inside the collecting bin 131, a slider 133 is installed on the top of the collecting bin 131, a base 134 is installed on the bottom of the collecting platform 132, a limiting ring 135 is installed on the side wall of the bottom cavity of the filter chamber 5, an electromagnet 136 is installed on the surface of the rotating plate, the electromagnet 136 is magnetically connected to the bottom of the electric telescopic rod 124, the filter element 8 is sleeved on the surface of the collecting bin 131, and the establishment of the collecting platform 132 can separate and collect harmful impurities. After the cleaning is completed, the collecting bin 131 can close the collecting platform 132, effectively preventing the leakage and spread of harmful substances and reducing the risk of secondary pollution.

[0026] As an embodiment of the present invention, the notch on the surface of the collecting bin 131 is consistent with the shape of the internal groove of the collecting platform 132; the surface of the slider 133 is inclined; a groove is provided at the bottom of the base 134, and a limiting rod is installed inside the limiting ring 135, and rounded corners are provided inside the groove and on the surface of the limiting rod. The top of the filter element 8 is sleeved on the bottom of the intake pipe 3, and a notch is provided at the bottom of the intake pipe 3, and it is matched with the protrusion of the inner wall of the filter element 8. The bottom of the filter element 8 is sleeved on the surface of the collecting bin 131, and the filter element 8 is rotatably connected to the surface of the collecting bin 131. The inclined surface of the slider 133 can make the harmful impurities that fall into the groove of the collecting platform 132, and the rounded corners of the groove and the surface of the limiting rod can make it more convenient to install.

[0027] like Figure 1 A control system of a smoke removal and purification device for an operating table is shown, and the control system includes the following parts: The control system includes a main control module, the main control module is connected to an air intake module, the air intake module is connected to a filter module, the filter module is connected to an exhaust module, the filter module is internally connected to a cleaning module, and the cleaning module is connected to the main control module by telecommunication; The air intake module is used to introduce the smoke generated by the operating room or surgical equipment, the filter module is used to filter and purify the harmful components in the smoke, the exhaust module is used to discharge the filtered air out of the equipment, and the cleaning module is used to remove the harmful substances remaining on the inner wall of the air intake pipe 3 and the filter element 8. The air intake module will pass the gas through the filter module and then through the exhaust module to discharge the purified gas. At this time, the main control module will drive the cleaning module to clean the inside of the filter module. The cleaning module regularly cleans the filter module to remove particulate matter, dust and other pollutants attached to the filter element 8, thereby reducing the loss of the filter element 8.

[0028] Working principle: When purifying harmful smoke, the motor 7 drives the collection bin 131 to rotate. Since the bottom of the filter element 8 is sleeved on the surface of the collection bin 131, and the filter element 8 is rotatably connected to the surface of the collection bin 131, when the electric telescopic rod 124 rotates, the scraper B129 cleans the inner wall of the filter element 8. At this time, the extended end of the electric telescopic rod 124 will extend upward, so that the insertion platform 127 moves upward, and then squeezes the plug block 128. When the plug block 128 is squeezed, the alcohol in the liquid storage bin 11 is transported to the water pipe 10, and then passes through the spray head 1 21 Spray alcohol onto the inner wall surface of the air inlet pipe 3, and clean the inner wall of the air inlet pipe 3 through the scraper A122. The scraper B129 cleans the inner wall of the filter element 8. The harmful substances will fall into the collecting table 132 through the surface gap of the collecting bin 131. Then, the motor 7 drives the electric telescopic rod 124 to rotate again. Since the bottom platform 134 is continuously limited by the limiting ring 135, the collecting table 132 will rotate inside the collecting bin 131. After the motor 7 drives the electric telescopic rod 124 to rotate at an appropriate angle, the groove of the collecting table 132 can be closed. When replacing the filter element 8, first disassemble the cover plate 2, and the cover plate 2 will leave the filter chamber 5 together with the rotating frame 9. At this time, the plug block 128 will leave the plug-in platform 127, and the alcohol inside can be replenished through the interface on the surface of the liquid storage bin 11. Then remove the filter element 8 from the surface of the collection bin 131. At this time, the electromagnet 136 disconnects the base 134 and the electric telescopic rod 124 and removes it, so that the impurities inside the collection platform 132 can be cleaned. When it is cleaned and needs to be installed, first connect the bottom of the electric telescopic rod 124 with the electromagnet 136. At this time, the bottom groove of the base 134 will be connected to the limit ring 135, and then the filter element 8 is sleeved on the surface of the collection platform 132. Finally, install the cover plate 2 on the upper end of the box body 1, and then insert the plug block 128 into the plug-in platform 127.
