Description

Technical Field

[0001] This application relates to the field of air disinfection, and more particularly, to an air disinfection and sterilization device for a medicine collection area. Background Art

[0002] Hospitals usually set up a separate medicine collection area, which is a relatively large room. After a patient finishes seeing a doctor in the hospital, the doctor issues a corresponding prescription, and then the patient takes the prescription to buy medicine. There are a relatively large number of people who need to collect medicine in the medicine collection area, which is likely to cause cross-infection between people. Especially when patients buy drugs with purchase quantity restrictions, such as Emticitabine Tablets. When patients collect medicine, doctors need to check the patients' purchase records. Generally, after buying drugs with restricted quantities last time, it takes some time before they can buy again. However, some patients may come to buy drugs with restricted quantities during the period when they are not allowed to buy. Doctors are unable to provide drugs to these patients, and patients often need to confirm with doctors the time when they can buy again or ask doctors to allow them to buy this time. This will lead to a longer time for doctors to provide drugs, resulting in more people in the medicine collection area and a greater risk of cross-infection between people.

[0003] Generally, a corresponding air filter is installed in the medicine collection area. The air filter uses an activated carbon filter element to filter the air, filtering and adsorbing dust and impurities in the air so that bacteria in the air are adsorbed by the activated carbon filter element, playing a role in disinfection and sterilization.

[0004] However, as patients continuously enter and leave the medicine collection area, dust will be brought into the medicine collection area, resulting in a large amount of dust in the medicine collection area for a long time. It is difficult to completely filter the dust, reducing the role of preventing cross-infection between people. Summary of the Invention

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

[0054] Refer to Figure 1-18 ,

[0055] An air disinfection and sterilization device for a medicine dispensing area, comprising: a device main body, a liquid guiding and filtering member 3, an activated carbon filtering member 4, and a rotating fan 5.

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

[0057] The liquid guiding filter element 3 is partially immersed below the liquid level of the disinfection liquid in the liquid storage chamber 12, forming a wet annular humidifying and filtering area with uniform distribution of the disinfection liquid. The annular humidifying and filtering area is located at the periphery of the liquid storage chamber 12. Among them, the liquid guiding filter element 3 can adopt a terry cloth 32 or other cloth bodies with capillary tubes inside. When the terry cloth 32 is partially immersed in the liquid, the part of the terry cloth 32 that is not immersed in the liquid will also be wetted accordingly by using the capillary tubes existing in the terry cloth 32. Therefore, the entire terry cloth 32 can be in a wet state, so that the disinfection liquid will wet the entire terry cloth 32, making the terry cloth 32 form an annular humidifying and filtering area. The external air will pass through the terry cloth 32, thus fully contacting the disinfection liquid. At the same time, it will also cause the disinfection liquid to evaporate, so that the disinfection liquid evaporates in the form of gas and is distributed in the air to disinfect the bacteria in the air. Among them, the disinfection liquid adopts a disinfection liquid that can evaporate and is harmless to the human body after evaporation. Or, the disinfection liquid adopts a disinfection liquid that is difficult to volatilize, and a mixture of the disinfection liquid and water is placed in the liquid storage chamber, where the water is used for evaporation and the disinfection liquid is used for air disinfection. Therefore, it plays a role in sterilizing and disinfecting the air and humidifying the air. Specifically, the liquid guiding filter element 3 further includes a support frame 31, and the terry cloth 32 is wrapped around the support frame 31 to form an annular humidifying and filtering area. The support frame 31 is located above the liquid storage chamber, and a part of the terry cloth 32 extends downward to below the liquid level of the liquid storage chamber.

[0058] The activated carbon filter element 4 forms an annular disinfection and sterilization filtering area, and the annular disinfection and sterilization filtering area is located at the periphery of the annular humidifying and filtering area. The activated carbon filter element 4 is an activated carbon filter element 41 used in an air filter, and the adsorbability of the activated carbon is used to adsorb dust impurities in the air, and viruses and bacteria generally exist on the dust impurities, so the function of disinfection and sterilization is realized. The annular disinfection and sterilization filtering area and the annular humidifying and filtering area are both located in the connection chamber 22. The rotary fan 5, the rotary fan 5 adopts an axial flow fan or a vortex fan, and in this solution, the axial flow fan is preferably adopted. The rotary fan 5 is arranged at the outlet 24 so that the external air passes through the inlet 23, the annular disinfection and sterilization filtering area, the annular humidifying and filtering area and the connection chamber 22 and is discharged at the outlet 24. That is, the rotary fan 5 is used to make the external air sequentially pass through the inlet 23, the activated carbon filter element 4, the liquid guiding filter element 3, the connection chamber 22 and the annular filter element 6 and then be discharged outward at the outlet 24. The external air will sequentially pass through the activated carbon filter element 4 and the liquid guiding filter element 3, so as to filter, sterilize, disinfect and humidify the external air and then discharge it outward, making the medicine-taking area safer and preventing the situation of excessive viruses in the medicine-taking area due to the entry and exit of various patients and causing infection.

[0059] In some other solutions, a water pump can also be arranged in the liquid storage chamber 12. The water pump uses corresponding pipelines to slowly pour the liquid in the liquid storage chamber 12 downward above the terry cloth 32, so as to increase the wetting speed of the terry cloth 32.

[0060] In one or some specific solutions, the device main body includes: a base 1 and a vertical cylinder 2. The base 1 is provided with a protruding block 11 for the vertical cylinder 2 to be inserted into, so that the vertical cylinder 2 and the base 1 form a detachable connection of plug-in fit. A liquid storage chamber 12 is formed on the protruding block 11. An installation groove 13 is formed on the protruding block 11, and the liquid guiding filter element 3 and the activated carbon filter element 4 are inserted into the installation groove 13, so that both the liquid guiding filter element 3 and the activated carbon filter element 4 can be detached relative to the base 1, which is convenient for replacement. Among them, the support frame 31 is a circular frame body, the support frame 31 is placed in the installation groove 13, and the terry cloth 32 is wrapped on the support frame 31. In some other solutions, the terry cloth 32 is replaced with a fiber filter element. The fiber filter element is a circular structure, and the fiber filter element is sleeved on the support frame 31. The fiber filter element is similar to the terry cloth 32 in material and both have capillary tubes, and the air permeability of the fiber filter element is better.

[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 a region on the protruding block 11, and the flat groove has a first limiting surface. A flat protrusion is formed on the inner wall surface of the vertical cylinder 2, and a second limiting surface 21 is formed on the flat protrusion. When the vertical cylinder 2 is inserted onto 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 connection chamber 22. A first electric connecting rod is arranged on the base 1, and a second electric 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 electric connecting rod and the second electric connecting rod abut against each other. A power supply wire is arranged on the base 1, so as to supply the electric energy on the base 1 to the rotary fan 5 on the vertical cylinder 2 by using the first electric connecting rod and the second electric connecting rod. Among them, the protruding block 11 includes a bottom frame 112 and an inserting frame 113, and the inserting frame 113 is inserted into the bottom frame 112, and the inserting frame 113 forms the installation groove 13. In some other solutions, the activated carbon filter element 4 includes an activated carbon filter element 41 and a filter element support 42. The filter element support 42 is used to install the activated carbon filter element 41, and the filter element support 42 is placed on the installation groove 13 and abuts against the support frame 31.

[0062] In some embodiments, the device body forms a conveying pipe with the outlet 24. The conveying pipe is formed on the vertical cylinder 2 and 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. A fixing frame for installing the rotary fan 5 is provided in the conveying pipe. The fixing frame, the rotary fan 5 and the vertical cylinder 2 are fixed together and thus are taken out on the base 1 together with the vertical cylinder 2. An annular filter element 6 is provided in the conveying pipe. The axis of the annular filter element 6 matches the axis of the conveying pipe. The rotary fan 5 is arranged in the middle of the annular filter element 6. The outlet 24 is opened on the side wall of the conveying pipe. The rotary fan 5 is used to make the external air pass through the inlet 23, the activated carbon filter element 4, the liquid guide filter element 3, the connection chamber 22 and the annular filter element 6 in sequence and then be discharged outward at the outlet 24, or the rotary fan 5 is used to make the external air pass through the outlet 24, the annular filter element 6, the connection chamber 22, the liquid guide filter element 3 and the activated carbon filter element 4 in sequence and then be discharged outward at the inlet 23. When the rotary fan 5 is an axial flow fan, the direction change of air inlet and outlet is realized by the forward rotation or reverse rotation of the rotary fan 5.

[0063] Through the above solution, in the normal use process, air is filtered by the activated carbon filter element 4, then filtered by the liquid guide filter element 3, and then filtered twice by the annular filter element 6 and then discharged outward. After a long time of use, too much dust and impurities adhere to the activated carbon filter element 4, resulting in poor air permeability and reduced disinfection effect. In order to improve this phenomenon, air is made to enter from the annular filter element 6, pass through the liquid guide filter element 3 and then be blown out reversely at the position of the activated carbon filter element 4 to blow and clean the activated carbon filter element 4. This is convenient for maintaining the disinfection and filtration effect of the activated carbon filter element 4 for a long time. At the same time, the normal rotation of the rotary fan 5 will also blow and clean the annular filter element 6. The purpose of setting the annular filter element 6 is to make the air for blowing and cleaning the activated carbon be sterile and dust-free air, so as to avoid bacteria and dust impurities gathering in the connection chamber 22 and affecting the disinfection and filtration effect. And the activated carbon filter element 4 can also make the sterile and dust-free air blow and clean the annular filter element 6.

[0064] In some other embodiments, legs 14 are provided at the bottom of the device main body to form a gap between the bottom of the device main body and the ground. A first stopper 7 is provided at the inlet 23, and the first stopper 7 switches between a state of blocking the inlet 23 and a state of opening the inlet 23. A first drain port 15 communicating with the gap is formed at the bottom of the device main body; the first drain port 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, and it is manually operated to wrap the vertical cylinder 2 to block the drain port, or it is manually removed. The first stopper 7 may further include a tightening roller 71 and a blocking cloth 72. The blocking cloth 72 is an airtight cloth body. The blocking cloth 72 is wound around the tightening roller 71, and the tightening roller 71 tightens and winds the blocking cloth 72. A limiting rod 73 is provided at the end of the blocking cloth 72, an installation plate is provided on the vertical cylinder 2, and the tightening roller 71 is provided on the installation plate. The tightening roller 71 can rotate and be wound by arranging a torsion spring or a snap spring on the roller body, such as the structure of a tape measure. The limiting rod 73 abuts against the installation plate to complete the winding. Manually pull out the blocking cloth 72 on the limiting rod 73 and then surround the vertical cylinder 2 so that the blocking cloth 72 blocks the inlet 23. A card slot 74 is provided on the installation plate. After the blocking cloth 72 blocks the inlet 23, the limiting rod 73 is placed in the card slot 74, and the tightening roller 71 is used to tighten the blocking cloth 72 on the vertical cylinder 2 to realize the state switching between blocking and opening the inlet 23. After the inlet 23 is blocked, air will only be discharged downward into the gap at the position of the first drain port 15. A container filled with disinfectant can be placed in the gap manually, so that the air discharged outward with bacteria and dust impurities will first come into contact with the disinfectant and then be discharged into the air outward. When the activated carbon filter element 4 is back blown and cleaned, it also plays a role in filtering and sterilizing, and prevents the bacteria and dust impurities filtered out from being directly back blown into the air.

[0065] In some other embodiments, a second drain port 251 is formed at the end of the delivery pipe; a second stopper 75 is provided at the outlet 24; the second stopper 75 switches between a state of blocking the outlet 24 and a state of opening the outlet 24. The second stopper 75 is similar in structure to the first stopper 7, the difference being that the first stopper 7 is provided at the inlet 23 on the vertical cylinder 2, and the second stopper 75 is provided at the outlet 24 of the delivery pipe.

[0066] Among them, in a specific solution, a first connecting pipeline 8 is provided at the first discharge port 15, and a second connecting pipeline 81 is provided at the second discharge port 251. One end of the first connecting pipeline 8 communicates with the first discharge port 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 discharge port 15 is added to the liquid storage chamber 12. One end of the second connecting pipeline 81 communicates with the second discharge port 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 discharge port 251 is added to the liquid storage chamber 12. Therefore, the air with bacteria and dust impurities cleaned by back blowing can be more conveniently introduced into the disinfectant for disinfection treatment.

[0067] In a more specific solution, a cover plate 25 is provided on the conveying pipe, and the cover plate 25 is detachably embedded at the port of the conveying pipe. The detachable connection between the cover plate 25 and the conveying pipe is realized, so it is convenient to remove the cover plate 25 to replace the annular filter element 6. Among them, the second discharge port 251 is formed on the cover plate 25. After one end of the second connecting pipeline 81 is fixedly connected to the second discharge port 251, the other end extends along the outer wall of the conveying pipe and enters the connection chamber 22 in the vertical cylinder 2. The second connecting pipeline 81 is fixed to the outer wall of the conveying pipe by a strap. Thus, when the cover plate 25 is removed from the conveying pipe, the second connecting pipeline 81 plays a role in connecting the cover plate 25. Therefore, the cover plate 25 does not need to be handled. Just let go of the hand, and the cover plate 25 will not automatically fall to the ground. Thus, it is convenient to place the cover plate 25 after it is removed and also prevents the cover plate 25 from being lost.

[0068] Or, when the conveying pipe is vertically arranged, air is discharged outward from the outlet 24. However, the outlet 24 is arranged on the outer wall surface of the conveying pipe. In the case where the overall height of the equipment main body is limited, it is difficult to output the air to a higher position, and the air can only be conveyed horizontally to a single height position range, resulting in the inability to use the filtered air to replace the air at a high position. Therefore, 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 open the cover plate 25 to open the end of the conveying pipe. Therefore, 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 is conducive to accelerating the speed and effect of overall disinfection of the medicine-taking area.

[0069] Or, when the conveying pipe is horizontally or obliquely arranged, the opening of the cover plate 25 can also play the above role, and at the same time, it will not cause the loss of the cover plate 25. When only the annular filter element 6 needs to be cleaned, just cover the end of the conveying pipe with the cover plate 25 and block the outlet 24 with the second baffle 75. The use process is also convenient to provide more usage modes and the user experience is better.

[0070] Since the vertical cylinder 2 is detachably inserted into the base 1, and the second connecting pipe 81 needs to be inserted into the liquid storage chamber 12 on the base 1, the second connecting pipe 81 will affect the disassembly of the vertical cylinder 2. For this reason, in this solution, an insertion pipe 82 is provided in the connection chamber 22. The insertion pipe 82 is fixed to the inner wall of the connection chamber 22. An air groove 28 is formed on the outer wall of the vertical cylinder 2. The end of the second connecting pipe 81 is inserted into the air groove 28, and the insertion pipe 82 communicates with the air groove 28, so that the second connecting pipe 81 communicates with the insertion pipe 82. When the vertical cylinder 2 is installed on the base 1, the insertion pipe 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, which is convenient for adding disinfectant and water.

[0072] Preferably, in this solution, the conveying pipe is vertically arranged. The conveying pipe is a part above the vertical cylinder 2 and is fixed to the vertical cylinder 2. A baffle 26 is arranged in the conveying pipe. The baffle 26 is fixed to the inner wall surface of the connection chamber 22 through a rod body. The eddy current fan is arranged below the baffle 26. There is a gap between the baffle 26 and the connection chamber 22, and this gap is the liquid injection port 27. The upper part of the conveying pipe is a cover plate 25. When injecting water, the cover plate 25 is opened, and water and disinfectant are poured on the baffle 26. The upper surface of the baffle 26 forms an arc-shaped downward-extending guiding surface, so that the water and disinfectant can more easily converge to the edge of the baffle 26, and the water and disinfectant can more easily be added to the connection chamber 22. In addition, the fixing frame is used to install the eddy current fan. The lower part of the fixing frame forms a plane. When the vertical cylinder 2 is installed on the base 1, the lower part of the fixing frame contacts the upper end of the support frame 31. Therefore, a chamber for preventing water from splashing when adding water will be formed above the liquid storage chamber 12. Preventing water from splashing is mainly achieved through the disinfection, sterilization and filtration element. An inwardly protruding structure is formed on the inner wall at the end position of the conveying pipe. The baffle 26 is a circular plate body, and the liquid injection port 27 is an annular opening. The setting of the inwardly protruding structure formed on the inner wall at the end position of the conveying pipe is to make the projection of the liquid injection port 27 on the ground located inside the projection of the disinfection, sterilization and filtration element on the ground. Thus, when adding water and disinfectant, it will be blocked by the disinfection, sterilization and filtration element, so that more water and disinfectant can be added to the liquid storage chamber 12. Among them, the baffle 26 is located below the end face of the conveying pipe, so that the water and disinfectant added to the baffle 26 are prevented from splashing out too fast due to excessive acceleration, but are more blocked by the conveying pipe. Among them, the baffle 26 is installed above the fixing frame, and the rotary 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 conveying pipe for a certain distance, the second connecting pipeline 81 enters the connecting chamber 22 inside the vertical cylinder 2. The position where the insertion pipe 82 communicates with the air groove 28 is below the eddy current fan and above the disinfection and sterilization filter element. The insertion pipe 82 is inserted into the inside of the disinfection and sterilization filter element. Therefore, when the vertical cylinder 2 is disassembled, the second connecting pipeline 81 does not affect the normal disassembly convenience. The lowermost position of the insertion pipe 82 is higher than the lowermost position of the vertical cylinder 2. Therefore, after the vertical cylinder 2 is disassembled, the vertical cylinder 2 can be directly placed upright on the ground without damaging the insertion pipe 82.

[0074] More specifically, in order to enable the annular filter element 6 to be removed at the top of the vertical cylinder 2, that is, at the end of the conveying pipe, in this solution, the vertical cylinder 2 includes a cylinder body 16 and an insertion body 17. The insertion body 17 is an annular shell. The liquid injection port 27, the baffle plate 26, and the fixing frame are all fixed to the insertion body 17. The insertion body 17 is detachably connected to the cylinder body 16, so as to realize the disassembly of the annular filter element 6 at the end of the conveying pipe. In addition, a disassembly port is opened on the side surface of the vertical cylinder 2, and a sealing door is arranged at the disassembly port. The sealing door is detachably connected to the disassembly port, so that the annular filter element 6 can be disassembled at the disassembly port.

[0075] In some more specific embodiments, a sealing shell 9 is arranged in the liquid storage chamber 12. The sealing shell 9 forms a treatment chamber 91 with through holes in the liquid storage chamber 12. The through holes are located above the liquid level in the liquid storage chamber 12; the first connecting pipeline 8 and the second connecting pipeline 81 are both inserted into the treatment chamber 91, so that the first connecting pipeline and the second connecting pipeline are both located below the liquid level in 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 into the disinfectant liquid, and then discharged outward through the through holes after passing through the disinfectant liquid. Subsequently, according to the rotation direction of the rotary fan 5, it is discharged outward through the inlet 23 or the outlet 24. This makes the overall structure 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 arranged at the lower part of the sealing shell 9. The sponge pad 92 makes there be 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 treatment chamber 91. Therefore, after the dust impurities enter the treatment chamber 91, the dust impurities will be blocked by the sponge pad 92 and cannot enter the remaining disinfectant liquid, thereby avoiding more dust impurities in the liquid storage chamber 12. In addition, two sealing shells 9 are arranged. One of the sealing shells 9 is directly or indirectly communicated with the first connecting pipeline 8, and the other sealing shell 9 is directly or indirectly communicated with the second connecting pipeline 81.

[0077] In some other solutions, a temperature control component can be arranged between the disinfection and sterilization filtration area and the annular humidification filtration area; the temperature control component is used to form an annular temperature control area, and the temperature control area heats or cools the liquid guide filtration member 3 and the activated carbon filtration member 4. The temperature control component adopts a small heater and a cooler, where the heater is, for example, a heating pipe, and the cooler is, for example, an evaporator. Moreover, the heater and the cooler are evenly distributed. When heating is required, the heating pipe is started, and the heating pipe is used to heat the air, achieving a heating effect, and at the same time, sterilization can also be carried out using the high temperature after heating. The cooler is used to cool the air.
