Description

Technical Field

[0001] The present application relates to the field of air disinfection, and in particular, to an air disinfection and sterilization device for a medicine collection area. Background Art

[0002] The hospital will set up a separate area for picking up medicines, which is a larger room. After the patient has finished the consultation in the hospital, the doctor will write the corresponding medicine collection order, and then the patient will take the medicine collection order to buy the medicine. There are many people who need to pick up medicines in the medicine collection area, which can easily cause mutual infection between people. Especially when patients are buying medicines with limited purchase quantities, such as emtinovir tablets. When patients pick up medicines, doctors need to check the patient's purchase records. Generally speaking, it will take some time after the last purchase of a limited number of medicines before they can continue to buy. However, some patients will buy limited numbers of medicines during the period when they cannot buy them. Doctors cannot provide patients with medicines. Patients often confirm the time they can buy with the doctor or ask the doctor to allow them to buy this time. This will cause the doctor to take longer to provide the medicine, resulting in more people in the medicine collection area and a greater risk of mutual infection between people.

[0003] Generally, the medicine collection area will be equipped with corresponding air filters. The air filters use activated carbon filters to filter the air, filter and adsorb dust and impurities in the air, so that the bacteria in the air are adsorbed by the activated carbon filter, which plays a role in disinfection and sterilization.

[0004] However, as patients continue to enter and leave the medication area, dust will be brought into the medication area, resulting in a large amount of dust in the medication area for a long time. It is difficult to completely filter the dust, resulting in a reduction in the effect of preventing mutual infection between people. Summary of the invention

[0053] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0054] Reference Figure 1-18 ,

[0055] An air disinfection and sterilization device for a medicine taking area comprises: an equipment body, a liquid guiding filter element 3, an activated carbon filter element 4 and a rotating fan 5.

[0056] The device body is formed with a liquid storage chamber 12 for storing disinfectant, a connecting chamber 22, and an inlet 23 and an outlet 24 communicated with the connecting chamber 22. The liquid storage chamber 12 is communicated with the connecting chamber 22. The connecting chamber 22 is located above the liquid storage chamber 12. The inlet 23 can be located at the lower part or the lower side wall of the device body, and the corresponding outlet 24 is located at the upper part or the upper side wall of the device body; the inlet 23 is located at the upper part or the upper side wall of the device body, and the corresponding outlet 24 is located at the lower part or the lower side wall of the device body.

[0057] The liquid-conducting filter element 3 is partially immersed below the liquid level of the disinfectant in the liquid storage chamber 12, forming a moist annular humidification and filtration area where the disinfectant is evenly distributed. The annular humidification and filtration area is located at the periphery of the liquid storage chamber 12. The liquid-conducting filter element 3 can be made of a towel cloth 32 or other cloth body with capillaries inside. By utilizing the capillaries in the towel cloth 32, when the towel cloth 32 is partially immersed in the liquid, the part of the towel cloth 32 that is not immersed in the liquid will also be wetted. Therefore, the entire towel cloth 32 can be in a moist state, so that the disinfectant will wet the entire towel cloth 32, so that the towel cloth 32 forms an annular humidification and filtration area. The external air will pass through the towel cloth 32, so as to fully contact with the disinfectant, and at the same time, the disinfectant will evaporate, so that the disinfectant evaporates in the form of gas and is distributed in the air, thereby disinfecting the bacteria in the air. The disinfectant uses a disinfectant that can evaporate and is harmless to the human body after evaporation. Alternatively, the disinfectant is a non-volatile disinfectant, and a mixture of the disinfectant and water is placed in the liquid storage chamber, wherein the water is used for evaporation and the disinfectant is used for disinfecting the air. Therefore, the air is sterilized and humidified. Specifically, the liquid-conducting filter element 3 also includes a support frame 31, and a towel cloth 32 is wrapped on the support frame 31 to form an annular humidification filter area. The support frame 31 is located above the liquid storage chamber, and a portion of the towel cloth 32 extends downward to below the liquid level of the liquid storage chamber.

[0058] The activated carbon filter 4 forms an annular disinfection and sterilization filtration area, and the disinfection and sterilization filtration area is located at the periphery of the annular humidification filtration area. The activated carbon filter 4 is an activated carbon filter element 41 used in an air filter, which uses the adsorption of activated carbon to adsorb dust impurities in the air, and viruses and bacteria generally exist on dust impurities, thereby achieving the effect of sterilization. The disinfection and sterilization filtration area and the annular humidification filtration area are both located in the connecting chamber 22. The rotating fan 5, the rotating fan 5 adopts an axial flow fan or a vortex fan, and the axial flow fan is preferably adopted in this scheme. The rotating fan 5 is arranged at the outlet 24, so that the external air is discharged at the outlet 24 after passing through the inlet 23, the disinfection and sterilization filtration area, the annular humidification filtration area and the connecting chamber 22, that is, the rotating fan 5 is used to make the external air pass through the inlet 23, the activated carbon filter 4, the liquid guide filter 3, the connecting chamber 22 and the annular filter 6 in sequence and then be discharged outward at the outlet 24. The external air will pass through the activated carbon filter element 4 and the liquid filter element 3 in sequence, thereby filtering, sterilizing, disinfecting and humidifying the external air and then discharging it outside, making the medicine collection area safer and preventing the presence of too many viruses in the medicine collection area and causing infection due to the entry and exit of various patients.

[0059] In some other solutions, a water pump may be provided in the liquid storage chamber 12 , and the water pump uses corresponding pipelines to slowly pour the liquid in the liquid storage chamber 12 downward from above the terry cloth 32 , thereby increasing the speed at which the terry cloth 32 is soaked.

[0060] In one or some specific solutions, the main body of the device includes: a base 1 and a vertical cylinder 2. The base 1 has a protruding block 11 for the vertical cylinder 2 to be placed in, so that the vertical cylinder 2 and the base 1 form a plug-in detachable connection. A liquid storage chamber 12 is formed on the protruding block 11. A mounting groove 13 is formed on the protruding block 11, and the liquid guide filter 3 and the activated carbon filter 4 are inserted into the mounting groove 13, so that the liquid guide filter 3 and the activated carbon filter 4 can be disassembled relative to the base 1 for easy replacement. Among them, the support frame 31 is an annular frame body, the support frame 31 is placed in the mounting groove 13, and the towel cloth 32 is wrapped on the support frame 31. In other solutions, the towel cloth 32 is replaced by a fiber filter element, which is an annular structure. The fiber filter element is inserted into the support frame 31. The fiber filter element is similar to the towel cloth 32 in material, both have capillaries, and the fiber filter element has better air permeability.

[0061] In addition, the protruding block 11 is a circular protrusion, and a flat groove is formed on the protruding block 11. The flat groove is formed by cutting off an area on the protruding block 11, and the flat groove has a first limiting surface. A flat block protrusion is formed on the inner wall surface of the vertical cylinder 2, and a second limiting surface 21 is formed on the protrusion of the flat block. When the vertical cylinder 2 is inserted into the protruding block 11, the first limiting surface abuts against the second limiting surface 21, which is convenient for positioning the insertion of the vertical cylinder 2. Among them, the vertical cylinder 2 forms an inlet 23, an outlet 24 and a connecting chamber 22. A first electrical connecting rod is arranged on the base 1, and a second electrical connecting rod is arranged on the vertical cylinder 2. The abutment of the first limiting surface and the second limiting surface 21 is to make the first electrical connecting rod abut against the second electrical connecting rod. A power supply wire is arranged on the base 1, so that the first electrical connecting rod and the second electrical connecting rod are used to supply the electric energy on the base 1 to the rotating fan 5 on the vertical cylinder 2. The protruding block 11 includes a base frame 112 and an inserting frame 113, the inserting frame 113 is inserted into the base frame 112, and the inserting frame 113 forms a mounting groove 13. In other schemes, the activated carbon filter element 4 includes an activated carbon filter element 41 and a filter element bracket 42, the filter element bracket 42 is used to install the activated carbon filter element 41, and the filter element bracket 42 is placed on the mounting groove 13 and tightly pressed against the support frame 31.

[0062] In some embodiments, the device body forms an output pipe having the outlet 24. The output pipe is formed on the vertical cylinder 2, and the output pipe can be arranged vertically, horizontally, or obliquely. The rotary fan 5 is a vortex fan, or a combination of a vortex fan and an axial flow fan, and a fixing frame for mounting the rotary fan 5 is provided in the output pipe. The fixing frame, the rotary fan 5 and the vertical cylinder 2 are fixed together, and therefore are taken out from the base 1 together with the vertical cylinder 2. An annular filter element 6 is provided in the output pipe, and the axis of the annular filter element 6 matches the axis of the output pipe, and the rotary fan 5 is provided in the middle of the annular filter element 6. The outlet 24 is provided on the side wall of the output pipe. The rotating fan 5 is used to make the external air pass through the inlet 23, the activated carbon filter 4, the liquid guide filter 3, the connecting chamber 22 and the annular filter 6 in sequence and then be discharged outward at the outlet 24, or the rotating fan 5 is used to make the external air pass through the outlet 24, the annular filter 6, the connecting chamber 22, the liquid guide filter 3 and the activated carbon filter 4 in sequence and then be discharged outward at the inlet 23. When the rotating fan 5 is an axial flow fan, the direction of air inlet and air outlet is changed by rotating the rotating fan 5 forward or reversely.

[0063] Through the above scheme, the normal use process is that the air is filtered through the activated carbon filter 4, filtered through the liquid guide filter 3, and then filtered through the annular filter 6 for secondary filtration before being discharged. After a long time of use, too much dust and impurities adhere to the activated carbon filter 4, resulting in poor air permeability and reduced sterilization effect. In order to improve this phenomenon, the air enters from the annular filter 6, passes through the liquid guide filter 3, and then blows out in the opposite direction at the position of the activated carbon filter 4, and the activated carbon filter 4 is back-blown and cleaned. It is convenient to maintain the sterilization and filtration effect of the activated carbon filter 4 for a long time. At the same time, the normal rotation of the rotating fan 5 will back-blow and clean the annular filter 6. The purpose of the annular filter 6 is to make the air back-blown and cleaned for the activated carbon be sterile and dust-free air, so as to avoid bacteria and dust impurities from gathering in the connecting chamber 22, affecting the sterilization and filtration effect. The activated carbon filter 4 can also make the sterile and dust-free air back-blown and clean the annular filter 6.

[0064] In some other embodiments, a support leg 14 is provided at the bottom of the device body so that a gap is formed between the bottom of the device body and the ground. A first stopper 7 is provided at the inlet 23, and the first stopper 7 switches between blocking the inlet 23 and opening the inlet 23. A first row of ports 15 communicating with the gap is formed at the bottom of the device body; the first row of ports 15 is located at the periphery of the disinfection and sterilization area. The first stopper 7 is an airtight cloth body or an annular plate body, which is manually wrapped around the vertical cylinder 2 to block the row of ports, or is manually removed. The first stopper 7 may also include a tightening roller 71 and a stopper cloth 72, the stopper cloth 72 is an airtight cloth body, the stopper cloth 72 is wound around the tightening roller 71, the tightening roller 71 tightens and rolls up the stopper cloth 72, a limit rod 73 is provided at the end of the stopper cloth 72, a mounting plate is provided on the vertical cylinder 2, the tightening roller 71 is provided on the mounting plate, and the tightening roller 71 is provided with a torsion spring or a retaining spring on the roller body so that the tightening roller 71 can be rotated and rolled, such as the structure of a tape measure. The limit rod 73 is against the mounting plate to complete the winding. The cloth 72 on the limit rod 73 is manually pulled outward, and then wrapped around the vertical tube 2, so that the cloth 72 blocks the inlet 23. A slot 74 is set on the mounting plate. After the cloth 72 blocks the inlet 23, the limit rod 73 is placed in the slot 74, and the cloth 72 is tightened on the vertical tube 2 by the tightening roller 71 to achieve the state switching of blocking and opening the inlet 23. After the inlet 23 is blocked, the air will only be discharged downward into the gap at the position of the first row of ports 15. A basin of disinfectant can be manually placed in the gap, so that the air with bacteria and dust impurities discharged outward is first discharged into the air after contacting the disinfectant. When the activated carbon filter 4 is back-blown and cleaned, it also plays a role in filtering and sterilizing, and prevents the filtered bacteria and dust impurities from being directly back-blown into the air.

[0065] In some other embodiments, the end of the output pipe forms a second row of ports 251; a second stopper 75 is provided at the outlet 24; the second stopper 75 switches between blocking the outlet 24 and opening the outlet 24. The second stopper 75 is similar in structure to the first stopper 7, except that the first stopper 7 is provided at the inlet 23 of the vertical cylinder 2, and the second stopper 75 is provided at the outlet 24 of the output pipe.

[0066] Among them, in a specific solution, a first connecting pipeline 8 is provided at the first outlet 15, and a second connecting pipeline 81 is provided at the second outlet 251. One end of the first connecting pipeline 8 is connected to the first outlet 15, and the other end is directly or indirectly inserted below the liquid level of the liquid storage chamber 12, so that the air discharged from the first outlet 15 is added to the liquid storage chamber 12. One end of the second connecting pipeline 81 is connected to the second outlet 251, and the other end is directly or indirectly inserted below the liquid level of the liquid storage chamber 12, so that the air discharged from the second outlet 251 is added to the liquid storage chamber 12. Therefore, the air with bacteria and dust impurities cleaned by backblowing can be more conveniently introduced into the disinfectant for disinfection.

[0067] In a more specific solution, a cover plate 25 is provided on the delivery pipe, and the cover plate 25 is detachably embedded in the port of the delivery pipe. The cover plate 25 is detachably connected to the delivery pipe, so it is convenient to remove the cover plate 25 to replace the annular filter 6. Among them, the second row of ports 251 is formed on the cover plate 25, and after one end of the second connecting pipeline 81 is fixedly connected to the second row of ports 251, the other end extends along the outer wall of the delivery pipe into the connecting chamber 22 in the vertical cylinder 2. The second connecting pipeline 81 is fixed to the outer wall of the delivery pipe by a binding band, so that when the cover plate 25 is removed from the delivery pipe, the second connecting pipeline 81 plays the role of connecting the cover plate 25, so that the cover plate 25 does not need to be handled, and only needs to be released, and the cover plate 25 will not automatically fall to the ground, so that it is convenient to place the cover plate 25 after the cover plate 25 is removed, and it also prevents the cover plate 25 from being lost.

[0068] Alternatively, when the delivery tube is placed vertically, the air is discharged outward at the outlet 24, but the outlet 24 is arranged on the outer wall surface of the delivery tube, and when the height of the entire device body is limited, it is difficult to output the air to a higher position, and the air can only be transported to a single height position in the horizontal direction, resulting in the inability to use the filtered air to replace the air at a high position, so that the range of air filtration is small. For this reason, the outlet 24 can include a plurality of horizontally opened holes and a plurality of obliquely opened holes. Or the cover plate 25 is opened so that the end of the delivery tube is opened, so that the air can be discharged horizontally and vertically upward, so that the filtered air can be better dispersed into the entire medicine taking area, which can help to speed up the speed and effect of disinfection of the entire medicine taking area.

[0069] Alternatively, when the delivery pipe is placed horizontally or obliquely, the opening of the cover plate 25 can also play the above role, and will not cause the loss of the cover plate 25. When the annular filter element 6 is only needed to be cleaned, the cover plate 25 covers the end of the delivery pipe, and the second stopper 75 blocks the outlet 24. The use process is also convenient to provide more use modes, and the use experience is better.

[0070] Since the vertical tube 2 and the base 1 are plug-in and detachable, and the second connecting pipeline 81 needs to be inserted into the liquid storage chamber 12 on the base 1, the second connecting pipeline 81 will affect the disassembly of the vertical tube 2. For this reason, the present solution sets a plug 82 in the connecting chamber 22, the plug 82 is fixed to the inner wall of the connecting chamber 22, and an air groove 28 is formed on the outer wall of the vertical tube 2. The end of the second connecting pipeline 81 is inserted into the air groove 28, and the plug 82 is connected with the air groove 28, so that the second connecting pipeline 81 is connected with the plug 82. When the vertical tube 2 is installed on the base 1, the plug 82 is inserted below the liquid level of the liquid storage chamber.

[0071] A liquid injection port 27 is provided at the top of the vertical cylinder 2 for adding disinfectant and water.

[0072] In this solution, the delivery pipe is preferably placed vertically, and the delivery pipe is a part above the vertical cylinder 2 and is fixed to the vertical cylinder 2. A baffle 26 is provided in the delivery pipe, and the baffle is fixed to the inner wall surface of the connecting chamber 22 through a rod body, and a vortex fan is provided below the baffle 26. There is a gap between the baffle and the connecting chamber 22, and the gap is a liquid injection port 27. The upper part of the delivery pipe is a cover plate 25. When water is injected, the cover plate 25 is opened, and water and disinfectant are poured on the baffle plate 26. The upper surface of the baffle plate 26 forms an arc-shaped guide surface extending downward, so that water and disinfectant can more easily converge to the edge of the baffle plate 26, so that water and disinfectant can more easily be added to the connecting chamber 22. In addition, the fixing frame is used to install the vortex fan, and the lower part of the fixing frame forms a plane. When the vertical cylinder 2 is installed with the base 1, the lower part of the fixing frame contacts the upper end of the support frame 31, so that a chamber is formed above the liquid storage chamber 12 to prevent water from splashing when added, and the splashing of water is mainly achieved by the disinfection and sterilization filter. An inwardly protruding structure is formed on the inner wall at the end position of the delivery pipe, the baffle 26 is a circular plate body, and the injection port 27 is an annular opening. The inwardly protruding structure formed on the inner wall at the end position of the delivery pipe is set to make the projection of the injection port 27 on the ground inside the projection of the disinfection and sterilization filter on the ground, so that when adding water and disinfectant, it will be blocked by the disinfection and sterilization filter, so that more water and disinfectant are added to the liquid storage chamber 12. Among them, the baffle 26 is located below the end face of the delivery pipe, so that the water and disinfectant added to the baffle 26 are prevented from splashing outward due to excessive acceleration, but are more blocked by the delivery pipe. A baffle plate 26 is installed above the fixing frame, and a rotating fan 5 is installed below the fixing frame.

[0073] More specifically, after the second connecting pipeline 81 extends downward along the outer wall of the delivery pipe for a distance, the second connecting pipeline 81 enters the connecting chamber 22 inside the vertical tube 2. The position where the cannula 82 is connected to the air groove 28 is located below the vortex fan and above the disinfection and sterilization filter, and the cannula 82 is inserted into the interior of the disinfection and sterilization filter. Therefore, when the vertical tube 2 is disassembled, the second connecting pipeline 81 does not affect the normal disassembly convenience. The lowest position of the cannula 82 is higher than the lowest position of the vertical tube 2. Therefore, after the vertical tube 2 is disassembled, the vertical tube 2 can be directly placed vertically on the ground without causing damage to the cannula 82.

[0074] More specifically, in order to enable the annular filter 6 to be removed at the top of the vertical cylinder 2, i.e., the end of the delivery pipe, the vertical cylinder 2 of this solution includes a cylinder 16 and an insert 17. The insert 17 is an annular shell. The liquid injection port 27, the baffle plate 26, and the fixing frame are all fixed to the insert 17. The insert 17 is detachably connected to the cylinder 16, thereby realizing the annular filter 6 to be removed at the end of the delivery pipe. In addition, a disassembly port is provided on the side of the vertical cylinder 2, and a sealing door is provided at the disassembly port. The sealing door is detachably connected to the disassembly port, so that the annular filter 6 can be removed at the disassembly port.

[0075] In some more specific embodiments, a sealing shell 9 is provided in the liquid storage chamber 12, and the sealing shell 9 forms a processing chamber 91 with a through hole in the liquid storage chamber 12. The through hole is located above the liquid level of the liquid storage chamber 12; the first connecting pipeline 8 and the second connecting pipeline 81 are both inserted into the processing chamber 91, so that the first pipeline and the second pipeline are both located below the liquid level of the liquid storage chamber 12. Thus, the air with dust, impurities and bacteria in the first connecting pipeline 8 and the second connecting pipeline 81 will be added to the inside of the disinfectant, and then discharged outwardly through the through hole after passing through the disinfectant, and then discharged outwardly through the inlet 23 or the outlet 24 according to the rotation direction of the rotating fan 5. The overall structure is made more compact and occupies less space.

[0076] In addition, the sealing shell 9 is a shell, and the sealing shell 9 is directly placed on the bottom surface of the liquid storage chamber 12 or fixed to the bottom surface of the liquid storage chamber 12. A sponge pad 92 is provided at the lower part of the sealing shell 9, and the sponge pad 92 creates a gap between the sealing shell 9 and the liquid storage chamber 12. The sealing shell 9 and the sponge pad 92 form the above-mentioned processing chamber 91, so after dust impurities enter the processing chamber 91, the dust impurities will be blocked by the sponge pad 92 and cannot enter the rest of the disinfectant, thereby avoiding the presence of a large amount of dust impurities in the liquid storage chamber 12. In addition, two sealing shells 9 are provided, one of which is directly or indirectly connected to the first connecting pipeline 8, and the other sealing shell 9 is directly or indirectly connected to the second connecting pipeline 81.

[0077] In some other schemes, a temperature control element can be set between the disinfection and sterilization filter area and the annular humidification filter area; the temperature control element is used to form an annular temperature control area, and the temperature control area heats or cools the liquid guide filter element 3 and the activated carbon filter element 4. The temperature control element adopts a small heater and a refrigerator, wherein the heater is such as a heating tube and the refrigerator is such as an evaporator. The heater and the refrigerator are evenly distributed. When heating is required, the heating tube is started, and the heating tube is used to heat the air to achieve the effect of heating. At the same time, the high temperature after heating can also be used for sterilization. The refrigerator is used to cool the air.
