Description

Technical Field

[0001] The present invention relates to the technical field of community disinfection devices. More specifically, the present invention is a disinfection device for community care to prevent cross-infection. Background Art

[0002] Community care can also be called community health care or community health nursing. According to the definition of the American Nurses Association, community care is an integrated discipline that combines public health science and nursing theory to promote and maintain the health of community populations. Community care focuses on health, targets community populations, and aims to promote and maintain the health of community populations. Public health science is a science and art of preventing diseases, prolonging life, promoting physical and mental health, and improving work efficiency. In particular, it involves a disinfection device for preventing cross-infection in the community during the influenza period or the high-incidence period of infectious diseases. The disinfection device generally uses a fixed-point spraying method to disinfect a specific area in real time, such as the position of the gate machine at the entrance and exit of the community and the entrance and exit positions of public areas, so as to achieve fixed-point disinfection and prevent cross-infection among various populations in public areas.

[0003] However, in actual use, there are still some drawbacks. For example, in the current disinfection device, when atomizing and spraying drugs externally, after the drug output passes through the outlet position of the device, due to the shape limitation of the outlet, a conical area of drug delivery operation is usually formed. (After the drug is atomized and output through the outlet, it will be affected by the diffusion of air and generally form a conical diffusion area). This action area has disinfection dead corners when dealing with a large number of people at the public entrance and exit positions and cannot achieve a greater range of disinfection effects for a large number of people. Therefore, in terms of the disinfection measures for community public areas, further optimization is needed. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a disinfection device for community care to prevent cross-infection. By setting the sliding piece I, the sliding piece II, the sliding storage cavity and the diversion groove opening, and using the different volume distributions of the sliding piece I and the sliding piece II in the initial state, when the conveying pipeline is working, the strong side and the weak side are naturally distinguished, and during their movement, the strong and weak sides are alternated, so that the spraying head at the front end of the conveying hose maintains a fan-shaped trajectory of disinfection spraying range formed by a back-and-forth swing, thereby expanding the drug diffusion range, meeting the disinfection needs of a large number of people at the public entrance and exit positions, and avoiding the generation of disinfection dead corners, so as to solve the problems raised in the above background art.

[0005] To achieve the above object, the present invention provides the following technical solution: A disinfection device for community care to prevent cross-infection, including a fixed back plate, a disinfector is detachably installed on the side of the fixed back plate, an installation plate is arranged on the side of the disinfector, and at the front end of the disinfector; a delivery hose is connected, and the other end of the delivery hose is fixedly sleeved with a spray head. The spray head is integrally in the shape of a duckbill, and a rectangular outlet structure is gradually formed at its outlet end. On both sides of the inner wall of the delivery hose, a pair of sliding storage cavities are symmetrically opened. A sliding piece I and a sliding piece II are respectively slidably sleeved in the two sliding storage cavities. A fixed cross bar is jointly inlaid and installed on the inner sides of the sliding piece I and the sliding piece II. A plurality of diversion slots are equally spaced on the inner wall surfaces of the sliding piece I and the sliding piece II;

[0006] The sliding piece I is integrally in the shape of an arc-shaped sheet that bends inward, and its bending degree is consistent with the inner wall curvature of the delivery hose. The thickness of the sliding piece I gradually decreases from the end close to the spray head to the other end. The inner side curvature of the sliding piece I is smaller than its outer side curvature. The vertical cross-section of the sliding piece I is integrally in the shape of an acute triangle. The diversion slots are integrally in the shape of strips and are parallel to the sliding piece I as a whole. One end of the diversion slot extends out of the surface of the sliding piece I and forms a notch shape, and the other end forms a semicircle at the inner wall surface of the sliding piece I to form a head and tail. The diversion slots are gradually arranged in a narrowing trend from one side to the other side of the semicircular tail end. The tails of the plurality of diversion slots to the other end are gradually concentrated in an inclined shape with the center of the inner side arc of the sliding piece I as the base point.

[0007] In a preferred embodiment, the overall shapes of the sliding piece I and the sliding piece II are the same, and the volumes of the sliding piece I and the sliding piece II in the initial state are set to be one large and one small.

[0008] In a preferred embodiment, on the side of the fixed cross bar close to the fixed back plate, there are two symmetrically arranged wedge-shaped surfaces up and down. The two wedge-shaped surfaces jointly form a triangular structure, and the fixed cross bar is vertically distributed with the inner wall of the delivery hose. The number of the fixed cross bars is two, and the two fixed cross bars are respectively located on the upper and lower sides inside the sliding piece I and the sliding piece II.

[0009] In a preferred embodiment, the surfaces of the sliding piece I and the sliding piece II are both smooth, and the overall of the sliding piece I and the sliding piece II and the sliding storage cavity are in clearance fit.

[0010] In a preferred embodiment, the sliding piece I and the sliding piece II are integrally made of alloy or polyester material.

[0011] In a preferred embodiment, the cross-section of the diversion trough opening is semi-circular, and the inclination attitude of the diversion trough opening is consistent with the bending radian of the inner wall of the sliding piece I.

[0012] Technical effects and advantages of the present invention:

[0013] By setting the sliding piece I, the sliding piece II, the sliding storage cavity and the diversion trough opening, and using the mutual cooperation of them, due to the different volume distributions of the sliding piece I and the sliding piece II in the initial state, when the conveying pipeline is working, the strong side and the weak side are naturally distinguished. During their movement, when the moving volumes of the sliding piece I and the sliding piece II reach the balance value, the original balance state of the conveying hose will be broken, so that the strong and weak sides are alternated, and the spraying head at the front end of the conveying hose maintains a disinfection spraying range in a fan-shaped trajectory formed by a back-and-forth swing, thereby further expanding the diffusion range after the drug is atomized, and then meeting the disinfection needs of a large number of people at the public entrance and exit positions. At the same time, when disinfecting multiple people synchronously, the generation of disinfection dead corners can be avoided, thereby improving its practicability and the working effect of preventing infection, and improving the working quality of the equipment.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] As shown in the attached Figure 1 to the attached Figure 13 A disinfection device for community care to prevent cross-infection, including a fixed back plate 1. A sterilizer 3 is detachably installed on the side of the fixed back plate 1. An installation plate 2 is arranged on the side of the sterilizer 3. At the front end of the sterilizer 3; a delivery hose 4 is connected in a communicating manner. The other end of the delivery hose 4 is fixedly sleeved with a spray head 5. The spray head 5 is in an overall duckbill shape and gradually forms a rectangular outlet structure at its outlet end. A pair of sliding receiving cavities 6 are symmetrically opened on both sides of the inner wall of the delivery hose 4. A sliding piece I 7 and a sliding piece II 8 are respectively slidably sleeved inside the two sliding receiving cavities 6. A fixed cross bar 9 is jointly embedded and installed inside the sliding piece I 7 and the sliding piece II 8. A plurality of diversion groove openings 10 are equidistantly opened on the inner wall surfaces of the sliding piece I 7 and the sliding piece II 8. Through the above settings, the fixed cross bar 9 can form a whole with the sliding piece I 7 and the sliding piece II 8. When the two of them are replaced and moved, it can ensure that their moving speeds and moving distances are synchronized, further improving the matching accuracy of its structure. At the same time, through the special shape setting of the spray head 5, the atomized medicine can be sprayed out in a strip-shaped diffusion posture, thereby increasing the three-dimensional space range covered during spraying. At the same time, the duckbill-shaped spray head 5 can cooperate with the fan-shaped range during its swinging, further improving the effect and range of action of the atomized medicine dispersed into the air;

[0030] The sliding piece I 7 is integrally in the shape of an arc-shaped sheet that bends inward, and its curvature is consistent with the inner wall curvature of the conveying hose 4. The thickness of the sliding piece I 7 gradually decreases from the end close to the spray head 5 to the other end. The inner surface curvature of the sliding piece I 7 is smaller than its outer surface curvature. The vertical cross-section of the sliding piece I 7 is integrally in the shape of an acute triangle. The diversion groove opening 10 is integrally in a strip shape and is parallel to the sliding piece I 7 as a whole. One end of the diversion groove opening 10 extends out of the surface of the sliding piece I 7 and forms a notch shape, and the other end forms a semicircle at the inner wall surface of the sliding piece I 7 to form a closed loop. The diversion groove opening 10 is arranged to gradually narrow from one side to the other side of the semicircular end. The ends of multiple diversion groove openings 10 are gradually distributed in an inclined shape and concentrated with the center of the arc of the inner side surface of the sliding piece I 7 as the base point. With the above settings, through the design of multiple diversion groove openings 10, it can be ensured that the atomized drug airflow can effectively adhere to and output outward along the surface of the sliding piece I 7 or the sliding piece II 8 under the guiding action of the diversion groove opening 10, thereby effectively improving the output efficiency of the airflow. At the same time, it is ensured that the flow velocity of the atomized airflow at the outlet ends of the sliding piece I 7 and the sliding piece II 8 reaches the maximum, so as to increase the inertial force during the swing of the conveying hose 4 and the spray head 5, effectively assisting in enhancing the amplitude during its swing, thereby expanding its swing range and enhancing the practicality of the equipment operation.

[0031] Among them, a liquid storage cavity, an atomizer and a micro pump body are provided inside the disinfector 3. The atomizer and the micro pump body can both adopt common equipment models. The liquid storage cavity can be used to conveniently store the liquid medicine, and at the same time, the atomizer and the micro pump body can effectively pump out and atomize the liquid medicine, and then achieve the effect of quickly diffusing into the air in a specific area, further improving the use effect of the equipment.

[0032] The overall shapes of the sliding piece Ⅰ7 and the sliding piece Ⅱ8 are the same. The volumes of the sliding piece Ⅰ7 and the sliding piece Ⅱ8 in the initial state are set to be one large and one small. On the side of the fixed cross bar 9 close to the fixed back plate 1, there are two wedge-shaped surfaces symmetrically arranged up and down. The two wedge-shaped surfaces together form a triangular structure, and the fixed cross bar 9 is vertically distributed with the inner wall of the conveying hose 4. The number of the fixed cross bars 9 is two, and the two fixed cross bars 9 are respectively located on the upper and lower sides inside the sliding piece Ⅰ7 and the sliding piece Ⅱ8. The surfaces of the sliding piece Ⅰ7 and the sliding piece Ⅱ8 are both smooth, and the whole of the sliding piece Ⅰ7 and the sliding piece Ⅱ8 has a clearance fit with the sliding storage cavity 6. The whole of the sliding piece Ⅰ7 and the sliding piece Ⅱ8 is made of alloy or polyester material. By using the above settings of the sliding piece Ⅰ7 and the sliding piece Ⅱ8, through the asymmetric setting of the sliding piece Ⅰ7 and the sliding piece Ⅱ8 in the initial state, when working initially, the conveying hose 4 automatically divides into a strong side and a weak side, and swings and sprays drugs along a fan-shaped trajectory, so as to achieve the purpose of large-range and dead-angle-free disinfection, and further improve the working quality of the equipment.

[0033] Specifically refer to the attached instructions Figure 6 , the cross section of the diversion groove opening 10 is semi-circular, and the inclined posture of the diversion groove opening 10 is consistent with the bending radian of the inner wall of the sliding piece Ⅰ7.

[0034] The specific implementation mode is as follows: By using the shape and the overall inclined posture of the diversion groove opening 10, when the conveying hose 4 sprays and outputs drugs, the atomized drug airflow can effectively adhere to and output outward along the surface of the sliding piece Ⅰ7 or the sliding piece Ⅱ8 under the guiding action of the diversion groove opening 10, so as to effectively improve the output efficiency of the airflow and ensure that its output direction will not be interfered, and ensure its smooth discharge.

[0035] The working principle of the present invention:

[0036] The first step: First, the operator normally assembles each component of the device, and then normally uses the device.

[0037] Step 2: First, the operator normally fills the disinfector with disinfectant solution, and turns on the atomizing device inside to atomize the liquid medicine, which is then sprayed for disinfection through the delivery hose 4 and the spray head 5. At this time, the states of the sliding piece I 7 and the sliding piece II 8 extending outside the sliding storage cavity 6 have inconsistent volumes. Using their asymmetrical settings, when the atomized liquid medicine airflow passes through the surfaces of the sliding piece I 7 and the sliding piece II 8, on the side with the larger extended volume, the resistance to the liquid medicine airflow on one side inside the delivery hose 4 will be greater. At this time, one side of the airflow passes quickly, and the other side passes slowly, thus forming a pressure difference on both sides of the internal space of the delivery hose 4, causing the delivery hose 4 to naturally twist towards the weaker side (the side with fast flow rate is the strong area, and the side with slow flow rate is the weak area), thereby driving the delivery hose 4 and the spray head 5 at its front end to twist synchronously. Here, taking the sliding piece I 7 as the weaker side in the initial state as an example, the delivery hose 4 twists towards the side of the sliding piece I 7. And during the process of the delivery hose 4 swinging towards its side, affected by the swinging force when the delivery hose 4 twists, the sliding piece I 7 will gradually slide into the inside of the sliding storage cavity 6, while the sliding piece II 8 will gradually slide out of the other sliding storage cavity 6, thereby starting to exchange the volume sizes of the sliding piece I 7 and the sliding piece II 8 extending outside the sliding storage cavity 6. And during their movement, when the moving volumes of the sliding piece I 7 and the sliding piece II 8 reach the balance value, the original balance state of the delivery hose 4 will be broken, causing the strong and weak sides to alternate. At this time, the delivery hose 4 twists towards the side of the sliding piece II 8. When the delivery hose 4 moves to the maximum distance towards its side, the sliding piece I 7 is affected by the swinging force when the delivery hose 4 twists and gradually slides out of the inside of the sliding storage cavity 6, while the sliding piece II 8 gradually slides into the other sliding storage cavity 6. By repeating the above process in a cycle, the spray head 5 at the front end of the delivery hose 4 maintains a fan-shaped trajectory of disinfection spraying range formed by a back-and-forth swing, thereby expanding the drug diffusion range, meeting the disinfection needs of a large number of people at public entrances and exits, avoiding the generation of disinfection dead corners, and thus enhancing its practicality. Finally, the device completes the work process of disinfecting the public area and preventing infections, and that's it.

[0038] Step 3: First, the operator normally shuts down the device. Then, the operator checks whether the fixity between the various components of the device is normal. Then, the aging and severely worn parts inside the device are replaced and repaired.

[0039] The following points should be noted: First, in the description of this application, it should be noted that unless otherwise specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense, which can be a mechanical connection or an electrical connection, or can be the internal communication of two components, and can be directly connected.
