Description

Technical Field

[0001] The invention belongs to the field of medical technology, and in particular relates to medical air purification equipment. Background Art

[0002] Air purification refers to the removal of pollutants from the air through various technologies and methods to improve air quality and ensure that the air people breathe is cleaner and healthier. Air purification is very important in environments such as homes, offices, hospitals, industrial sites, etc., especially when the air quality is poor or there are special health needs.

[0003] Existing air purifiers usually use static solid-state activated carbon rings to adsorb pollutants in the air. Although this method can purify the air to a certain extent, it also has several significant problems. First, static solid-state activated carbon rings are prone to adsorb moisture and volatiles of disinfectant liquid in the air, causing clogging and solidification of activated carbon pores, resulting in a rapid decrease in its adsorption capacity, which in turn affects the long-term stability and efficiency of the equipment; secondly, these devices cannot effectively recover disinfectants such as alcohol in the air. After disinfection in the hospital, the disinfectant will evaporate into the air, causing adverse reactions such as respiratory irritation and allergic reactions in patients. In addition, the surface of activated carbon can easily become a breeding ground for bacteria, especially in a high humidity environment. This not only reduces the adsorption performance of activated carbon, but may also release pathogens back into the air, causing cross-infection. Summary of the invention

[0008] Preferably, the condensing mechanism includes a ring, which is fixedly sleeved on the top of the inner curved surface of the main shaft, and a sleeve shaft is fixedly sleeved on the inner curved surface of the ring, and the sleeve shaft is made of heat insulating material, and a plurality of connecting blocks are fixedly installed at equal intervals on the circumference of the inner curved surface of the sleeve shaft, and a cold rod is fixedly sleeved in the middle of the plurality of connecting blocks, and a collecting shell is fixedly sleeved on the bottom of the inner curved surface of the main shaft, and the cold rod is in direct contact with the collecting shell, and the collecting shell is made of heat conductive material.

[0012] The beneficial effects of the present invention are as follows:

[0013] The present invention starts the air suction mechanism to make the external air flow through the activated carbon between the outer breathable cover and the inner breathable cover. At this time, the activated carbon adsorbs pathogens, moisture, disinfectant and the like in the air. Then, by positively starting the telescopic rod, the compression mechanism pushes the activated carbon at the bottom between the inner curved surface of the outer shell and the outer curved surface of the inner shell below it to move upward from the bottom between the inner curved surface of the mounting sleeve and the outer curved surface of the main shaft to the grinding mechanism. The grinding mechanism grinds the activated carbon to break the activated carbon solidified by the adsorption of moisture, disinfectant and other liquids in the air, thereby overcoming the problem that the activated carbon absorbs liquid substances such as moisture in the air, resulting in a poor adsorption effect of the activated carbon, and at the same time improving the subsequent sterilization efficiency of the activated carbon by the hot plate.

[0014] In addition, the rotating turbine blows the ground activated carbon upward. When the activated carbon passes through the hot plate, the hot plate heats the activated carbon to kill the bacteria attached to the surface of the activated carbon. At the same time, the moisture, disinfectant and other liquids on the surface of the activated carbon evaporate to prevent bacteria from growing on the surface of the activated carbon. At the same time, the problem of activated carbon absorbing water and agglomerating is overcome, so that the activated carbon always maintains an effective adsorption effect. When the activated carbon moves upward and contacts the rotating centrifugal blades, the activated carbon flows through the connecting hole in the middle of the top cover to the inner cavity of the outer shell and the upper part of the outer curved pressure plate of the inner shell under the centrifugal collision of the centrifugal blades, and then the telescopic rod is started in the reverse direction. The treated activated carbon moves from the upper part of the compression mechanism to the lower part of the compression mechanism, and the activated carbon is squeezed, thereby realizing the circulation treatment of bacteria, moisture, disinfectant and other liquids attached to the active surface.

[0015] 3. In the present invention, when the hot plate heats and sterilizes the activated carbon, the moisture, alcohol and other disinfectants adsorbed by the activated carbon evaporate under the heating of the hot plate, and the evaporated gas flows through the isolation cloth to the bottom of the inner curved surface of the isolation cloth and the inner curved surface of the sleeve shaft, and then flows upward through the inner curved surface of the isolation cloth and the bottom of the inner curved surface of the sleeve shaft to the inner curved surface of the sleeve shaft and the outer curved surface of the cold rod. The upward-flowing gas condenses into liquid upon contact with the cold rod, and drips along the curved surface of the cold rod into the inner cavity of the collection shell, thereby recovering the alcohol and disinfectant in the air, thus solving the problem that after medical staff disinfect the ward, disinfectants such as alcohol evaporate into the air, causing adverse reactions such as respiratory irritation and allergic reactions in patients.

The outer curved surfaces of the plurality of connecting rings 603 are fixedly sleeved with outer rings 604, and the outer curved surfaces of the outer rings 604 are slidably sleeved with the inner curved surface of the outer shell 1. The inner curved surfaces of the plurality of connecting rings 603 are fixedly sleeved with inner rings 605, and the inner curved surfaces of the inner rings 605 are slidably sleeved with the outer curved surface of the inner shell 3. A limiting sleeve 606 is fixedly mounted on the bottom surface of the connecting ring 603, and the limiting sleeve 60 6 is slidably sleeved with a limit rod 607 in the middle part, and a pressure plate 608 is fixedly installed at the bottom end of multiple limit rods 607, and gaps are left between the pressure plate 608 and the inner curved surface of the outer shell 1 and the outer curved surface of the inner shell 3, so that when the telescopic end of the telescopic rod 602 drives the outer ring 604 and the inner ring 605 to move upward through the connecting ring 603, the pressure plate 608 is driven by gravity to move the limit rod 607 downward. At this time, the activated carbon on the upper part of the pressure plate 608 between the inner curved surface of the outer shell 1 and the outer curved surface of the inner shell 3 flows downward through the middle part of the outer ring 604 and the inner ring 605 along the gap between the pressure plate 608 and the outer shell 1 and the inner shell 3, thereby realizing the reflow of the activated carbon.

The sleeve shaft 1302 is made of heat-insulating material. The sleeve shaft 1302 is made of heat-insulating ceramics to prevent the heat generated by the hot plate 11 from being transferred to the inner cavity of the sleeve shaft 1302 through the main shaft 8 and the sleeve shaft 1302, causing the temperature of the cold rod 1304 to rise, resulting in the cold rod 1304 The condensation effect of the water, alcohol and other disinfectants in the air becomes worse, causing the recovery effect of the disinfectant such as alcohol to become worse, and the sleeve shaft 1302 is made of heat-insulating ceramics to prevent the heat generated by the hot plate 11 from being transferred to the inner cavity of the sleeve shaft 1302 through the main shaft 8 and the sleeve shaft 1302.

[0029] Working principle:

[0030] When the present invention is used, the air suction mechanism 7 is started, and the air suction mechanism 7 sucks air, and the air flows to the inner curved surface of the inner shell 3 and the outer curved surface of the mounting sleeve 4 through the outer air permeable cover 101, the activated carbon between the outer air permeable cover 101 and the inner air permeable cover 301, and the inner air permeable cover 301 in sequence, at which time the activated carbon adsorbs the pathogens, moisture, and disinfectant in the air, and the purified air flows to the outside air through the air outlet holes opened on the upper surface of the air suction mechanism 7 and the top cover 5, and then the driving member 801 is started, and the output end of the driving member 801 drives the main shaft 8 to rotate, and the main shaft 8 drives the fixing ring 901, the grinding disc 903, the turbine 10 and the centrifugal blade 12 fixedly sleeved therewith to rotate, and at the same time, the hot plate 11 and the cold rod 1304 are energized, at which time the hot plate 11 generates heat to increase the temperature, and the cold rod 1304 absorbs heat to cool down, and then the telescopic rod 602 is started forward, and the telescopic rod 602 is started forward. 02 telescopic end moves downward, and the telescopic end of the telescopic rod 602 pushes the pressure plate 608 to move downward through the connecting ring 603, the outer ring 604 and the inner ring 605. The pressure plate 608 pushes the activated carbon at the bottom between the inner curved surface of the outer shell 1 and the outer curved surface of the inner shell 3 below it to move upward from the bottom between the inner curved surface of the mounting sleeve 4 and the outer curved surface of the main shaft 8, and flows to the upper surface of the grinding seat 904 through the gap between the inner curved surface of the grinding seat 904 and the outer curved surface of the main shaft 8, pushing the grinding disc 903 to compress the elastic member 902 to move upward. At this time, the rotating grinding seat 904 grinds the activated carbon on the surface of the grinding seat 904, so that the solidified activated carbon due to the adsorption of moisture in the air, disinfectant and other liquids is broken, thereby overcoming the problem that the activated carbon absorbs liquid substances such as moisture in the air, resulting in a poor adsorption effect of the activated carbon, and at the same time improving the subsequent hot plate 11 The efficiency of sterilizing the activated carbon;

[0031] In addition, the rotating turbine 10 blows the ground activated carbon upward. When the activated carbon passes through the hot plate 11, the hot plate 11 heats the activated carbon to kill the bacteria attached to the surface of the activated carbon and evaporate the moisture, disinfectant and other liquids on the surface of the activated carbon to prevent bacteria from growing on the surface of the activated carbon. At the same time, the problem of activated carbon absorbing water and agglomerating is overcome, so that the activated carbon always maintains an effective adsorption effect. When the activated carbon moves upward and contacts the rotating centrifugal blades 12, the activated carbon flows through the connecting hole in the middle of the top cover 5 to the inner cavity of the outer shell 1 and the upper part of the outer curved pressure plate 608 of the inner shell 3 under the centrifugal collision of the centrifugal blades 12, and then the telescopic rod 602 is started in the reverse direction, and the telescopic end of the telescopic rod 602 passes through the connecting hole in the middle of the top cover 5 to the inner cavity of the outer shell 1 and the upper part of the outer curved pressure plate 608 of the inner shell 3. The outer ring 604 and the inner ring 605 are driven to move upward by the connecting ring 603. At this time, the pressing plate 608 moves under the action of gravity, and the pressing plate 608 pulls the limiting rod 607 to move downward along the limiting sleeve 606 until the upper part of the limiting rod 607 collides with the bottom of the limiting sleeve 606. At this time, the pressing plate 608 is separated from the outer ring 604 and the inner ring 605. At this time, the activated carbon treated on the upper part of the compression mechanism 6 flows to the bottom of the pressing plate 608 through the middle part of the outer ring 604 and the inner ring 605. Finally, the telescopic rod 602 is started forward to squeeze the activated carbon under the pressing plate 608, so as to realize the circulation treatment of liquids such as bacteria, moisture, disinfectant and the like attached to the surface of the activated carbon;

[0032] In addition, in the present invention, when the hot plate 11 heats and sterilizes the activated carbon, the moisture, alcohol and other disinfectants adsorbed by the activated carbon evaporate under the heating of the hot plate 11, and the evaporated gas flows through the isolation cloth 802 to the bottom of the inner curved surface of the isolation cloth 802 and the inner curved surface of the sleeve shaft 1302, and then flows upward through the inner curved surface of the isolation cloth 802 and the bottom of the inner curved surface of the sleeve shaft 1302 to the inner curved surface of the sleeve shaft 1302 and the outer curved surface of the cold rod 1304. The upward-flowing gas contacts the cold rod 1304 and condenses into liquid, and drips along the curved surface of the cold rod 1304 to the inner cavity of the collection shell 1305, thereby recovering the alcohol and disinfectant in the air.
