Description

Technical Field

[0001] The invention relates to the technical field of medicament spraying and disinfection, in particular to a safety door type medicament spraying device for achieving disease control and prevention. Background Art

[0002] Portal disinfection tunnels are a facility designed to fully disinfect personnel. In places with frequent traffic, such as hospitals and disease control centers, these tunnels can disinfect incoming personnel, preventing pathogens from entering the facility and protecting the health and safety of those inside.

[0003] Traditional disinfection channels generally consist of a frame structure, a spray system, an induction system, etc. A search revealed a disinfection channel disclosed in patent application number CN202020202698.6, whose main structure includes a main body, a base frame, support legs, a filter, a drain, an ozone water generator, an atomizer, an induced draft fan, pipes, a mist outlet, a door curtain, and other components.

[0004] It can be seen from its patent records that the above-mentioned disinfection channel is made of a profile frame combined with plastic cloth and curtain cloth, and an ozone water machine is used to use tap water as raw material to make ozone water with disinfection properties for spraying and disinfection. Its spray port is located at the top. This structural setting has the following problems in the actual disinfection process: the disinfection channel releases mist-like ozone water through the mist outlet of the top pipe of the main body for disinfection. The layout and angle of the mist outlet are fixed, and it is difficult to ensure the overall disinfection effect. The door curtain is composed of several vertically arranged curtain cloths, which are tightly fitted by mutual adsorption of magnetic strips. However, the magnetic strip adsorption method is prone to collision and pulling during the frequent entry and exit of people, causing the curtain cloth to separate, affecting the sealing of the door curtain; at the same time, different people will constantly touch the door curtain during entry, which is easy to cause cross infection.

[0005] It can be seen that the existing disinfection channel still has some problems in the process of spraying and disinfecting with chemicals.

DETAILED DESCRIPTION

[0043] The embodiments of the technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

[0044] The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are therefore only used as examples and are not intended to limit the scope of protection of the present invention.

[0045] The specific structure of the present invention is as follows Figures 1-15 As shown in .

[0046] Example 1: A safety door-type drug spraying device for achieving disease control and prevention, comprising a fixed ground-connected seat 1, with ground-connected rails 2 integrally formed on the tops of the left and right sides of the ground-connected seat 1, and two spraying and disinfecting units spaced apart along the length direction above the ground-connected seat 1, the bottoms of the two spraying and disinfecting units are slidably mounted on the two ground-connected rails 2 through the translational slides 18 at the bottoms thereof, the two spraying and disinfecting units are connected by a door-type telescopic passage 3, the two spraying and disinfecting units and the door-type telescopic passage 3 together constitute a disinfection passage for people to pass through, and a first disinfection area 4 and a second disinfection area 5 are respectively provided inside the front spraying and disinfecting unit and inside the rear spraying and disinfecting unit.

[0047] The entire safety door-type drug spraying device is fixedly installed with a ground seat 1. Before installation, the door-type telescopic channel 3 is first docked and fixedly connected to the spraying and disinfection units on both sides. At this time, a long strip of disinfection channel is formed inside the three. The door-type telescopic channel 3 can be controlled to be extended to an appropriate length as needed, so as to control the interval distance between the two spraying and disinfection units, and finally achieve the purpose of controlling the interval prevention and control distance between the first disinfection area 4 and the second disinfection area 5 according to the current prevention and control needs; when the passing personnel are tested, the first disinfection area 4 and the second disinfection area 5 have people to be disinfected standing at the same time, so that disinfection inspections of two people are carried out at the same time, and the same person to be tested completes the first disinfection in the first disinfection area 4, and performs the second disinfection in the second disinfection area 5 after the first disinfection is completed. When the previous person is in the second disinfection area 5 for the second disinfection, the next person to be tested can stand in the first disinfection area 4 and start the first disinfection, which ensures the continuity of the disinfection test. At the same time, each person can be disinfected twice, which greatly improves the disinfection effect.

[0048] When it is necessary to control the distance between two people in the front and back during the disinfection process, the spacing between the translation slides 18 at the bottom of the two current spray disinfection units can be flexibly adjusted during installation, thereby driving the middle door-shaped telescopic channel 3 to extend and retract. After extension and retraction, the relative stability of the newly formed channel is guaranteed by the fixation of the two translation slides 18.

[0049] During the process of disinfecting personnel in the first disinfection area 4 and the second disinfection area 5, the spraying and disinfection units at the corresponding positions can quickly complete the disinfection of the personnel. At the same time, the air wall protection mode can be turned on during disinfection to ensure the relative air wall isolation of the first disinfection area 4 and the second disinfection area 5. At the same time, the relative isolation of the first disinfection area 4 and the second disinfection area 5 from the external area can also be ensured, so as to achieve effective isolation of internal personnel and external inspection personnel, and ensure the relative independence of the first disinfection area 4 and the second disinfection area 5. At the same time, during the disinfection process, the external ventilation equipment is promptly cooperated to discharge the spray mist, airflow, etc. inside the first disinfection area 4 and the second disinfection area 5 to the outside, so as to ensure the relative cleanliness of the first disinfection area 4 and the second disinfection area 5 and reduce the probability of cross infection.

[0050] In any of the above schemes, it is preferred that the spraying and disinfection unit includes a door-type frame 6, and a vertical through-channel 7 is provided in the middle of the vertical sections on both sides of the door-type frame 6, and a spraying control mechanism is installed in each of the vertical through-channels 7. The lower end of the spraying control mechanism is movably inserted into the bottom mounting hole of the vertical through-channel 7, and the top of the spraying control mechanism is movably passed through the top of the door-type frame 6 and is connected to the corresponding drive transmission mechanism. Multidirectional spray units are installed on the inner side walls of the two lifting and sliding seats 8 of the spraying control mechanism, and each of the multidirectional spray units is composed of A three-way bellows 9 with a valve installed in the vertical through channel 7 outside the spray control mechanism is connected to an external medicine supply device, and a ventilation pipe 10 is installed in the top middle section of the door frame 6. The bottom of the ventilation pipe 10 is connected to the disinfection channel inside the door frame 6, and the top of the ventilation pipe 10 is connected to the external ventilation equipment through a pipeline. The bottoms of the two vertical sections of the door frame 6 are both installed on the top of the corresponding translation slide 18 below them, and the first disinfection area 4 or the second disinfection area 5 for personnel to stand is provided on the top of the translation slide 18.

[0051] Multi-directional spray units are installed on the inner walls of the two lifting and sliding seats 8 of the spray control mechanism. They can spray the disinfectant from multiple directions at people passing by, ensuring that all parts of the body are exposed to the disinfectant, improving the comprehensiveness and effectiveness of disinfection. When the first disinfection zone 4 and the second disinfection zone 5 are operating simultaneously, the multi-directional spray units can quickly and comprehensively disinfect the entire body of the person standing in them, achieving efficient sterilization.

[0052] Each multi-directional spray unit is connected to an external drug supply device via a three-way bellows 9 installed in a vertical through-channel 7, ensuring a continuous and stable supply of drugs to meet the disinfection needs when a large number of people pass through, and the three-way bellows 9 can adapt to the movement of the spray control mechanism to a certain extent without affecting the delivery of drugs. Whether the disinfection operation is carried out in the first disinfection area 4 or the second disinfection area 5, an adequate supply of drugs can be ensured to maintain a stable disinfection effect. Inside the spray disinfection unit on the front and rear sides, a first disinfection area 4 and a second disinfection area 5 are provided respectively. Personnel first undergo preliminary disinfection in the first disinfection area 4, and then undergo further disinfection in the second disinfection area 5. This double disinfection mode enhances the disinfection effect and reduces the possibility of residual pathogens.

[0053] In actual work, the two disinfection areas can accommodate different personnel to perform disinfection operations at the same time. When the previous person completes the first disinfection in the first disinfection area 4 and enters the second disinfection area 5 for the second disinfection, the subsequent personnel to be tested can immediately enter the first disinfection area 4 to start the first disinfection, ensuring the continuity of the disinfection test, and everyone can receive two disinfections, which greatly improves the disinfection effect. The bottom of the spray disinfection unit is installed on the ground track 2 through a sliding seat 18, so that the two spray disinfection units can move along the length of the ground seat 1. Such a design can flexibly adjust the width of the disinfection channel according to actual use needs to adapt to different places and personnel flow conditions.

[0054] For example, the disinfection channel can be widened at the entrance of a passage with a large flow of people to facilitate the rapid passage of people; it can be appropriately narrowed in places with limited space.

[0055] When it is necessary to control the distance between two people in front and behind during the disinfection process, the spacing between the translation slides 18 at the bottom of the two spray disinfection units can be flexibly adjusted during the installation phase, thereby driving the door-shaped telescopic channel 3 in the middle to extend and retract. After the adjustment is completed, the translation slide 18 is fixed to ensure that the newly formed disinfection channel remains relatively stable. The two spray disinfection units are connected by the door-shaped telescopic channel 3. When the spray disinfection units move, the door-shaped telescopic channel 3 can also be extended and retracted, always maintaining the integrity of the disinfection channel, which does not affect the passage of people, but also ensures the continuity of the disinfection area and prevents the occurrence of disinfection blind spots.

[0056] Before installation, the door-shaped telescopic channel 3 is docked and fixedly connected to the spray disinfection units on both sides, forming a long strip of disinfection channel inside the three. According to prevention and control needs, the door-shaped telescopic channel 3 can be controlled to extend and retract to an appropriate length, thereby flexibly adjusting the distance between the two spray disinfection units and achieving precise control of the distance between the first disinfection area 4 and the second disinfection area 5. A ventilation pipe 10 is installed in the middle of the top of the door frame 6. Its bottom is connected to the disinfection channel inside the door frame 6, and its top is connected to the external ventilation equipment through a pipeline.

[0057] The ventilation equipment continuously extracts the air in the disinfection channel through the ventilation pipe 10 and replenishes fresh air. On the one hand, it can promptly discharge the drug mist and odor generated during the disinfection process, improving the breathing environment when people pass through; on the other hand, it avoids excessive accumulation of disinfectants in the channel, ensuring the continuity and stability of the disinfection effect.

[0058] When personnel disinfection operations are being performed simultaneously in the first and second disinfection areas 4, the ventilation equipment can promptly discharge the mist and airflow generated by the internal spraying, maintaining the relative cleanliness of the air in both disinfection areas and reducing the risk of cross-infection. The two spray disinfection units and the door-shaped telescopic channel 3 together form a disinfection passage for personnel to pass through. The height and width of the passage should be designed in accordance with ergonomics to ensure normal and comfortable passage for personnel.

[0059] The first disinfection area 4 and the second disinfection area 5 set in the passage provide space for personnel to undergo comprehensive disinfection during the passage, ensuring that personnel are effectively disinfected before entering a specific place. When the flow of personnel is large, the passage design can ensure that personnel pass through in an orderly manner and complete the disinfection process, thereby improving the passage efficiency. The first disinfection area 4 or the second disinfection area 5 for personnel to stand is set on the top of the translation slide 18. When entering the disinfection passage, personnel stand in the designated area, which can better cooperate with the spraying of the multi-directional spray unit, ensure the consistency of the disinfection effect, and also facilitate the standardization of the passage process of personnel.

[0060] In actual operation, the first disinfection area 4 and the second disinfection area 5 carry people for disinfection at the same time, and the standardized standing area setting helps to maintain the efficiency and stability of the disinfection process.

[0061] When the person to be tested enters the disinfection passage inside the door-type model, the sensor configured on the top of the door-type model can sense that someone has entered. At this time, the control system controls the external agent supply equipment to supply agents to each multi-directional spray unit. After passing through the external pipeline and the three-way bellows 9, the agent enters the corresponding multi-directional spray unit. At this time, the agent is sprayed in a spray form onto the body surface of the person standing in the disinfection area for atomized spray disinfection.

[0062] During the disinfection process, the operation of the driving transmission mechanism can be controlled to simultaneously control the operation of the spraying position control mechanisms on both sides. During the operation of the spraying position control mechanism, the lifting sliding seat 8 can be driven to move relatively close or relatively far away. In this process, the corresponding three-way bellows 9 can be driven to extend and retract. At the same time, the multi-directional spray units can be controlled to lift relative to or back to back. During the lifting process, the mist agent can be sprayed towards the personnel at the same time, thereby ensuring the comprehensiveness of the disinfection position of the personnel and improving the spray disinfection effect.

[0063] After the personnel have completed disinfection in the first disinfection area 4, they can proceed to the second disinfection area 5 and quickly complete disinfection in the second disinfection area 5. The disinfection of the second disinfection area 5 does not affect the normal disinfection of the first disinfection area 4, thus ensuring the efficiency and effectiveness of the disinfection. Different disinfectant sprays can be used in the first disinfection area 4 and the second disinfection area 5 to achieve the purpose of improving the killing effect of viruses and bacteria.

[0064] In addition, when disinfecting in the first disinfection area 4, two multidirectional spray units can be used in a manner of relatively far away disinfection from the middle to the upper and lower parts, so that the human trunk is disinfected first and then the upper and lower limbs, head and feet are disinfected; when disinfecting in the second disinfection area 5, two multidirectional spray units can be used in a manner of relatively close disinfection from the upper and lower parts to the middle, so that the upper and lower limbs, head and feet are disinfected first and then the trunk is disinfected. The combination of the two disinfection methods improves the comprehensiveness and efficiency of the disinfection.

[0065] In any of the above schemes, it is preferred that the spray control mechanism includes a bidirectional screw 11 vertically installed in the vertical through channel 7, the screw rotation directions of the upper and lower parts of the bidirectional screw 11 are opposite, the lower end of the bidirectional screw 11 is movably inserted in the mounting hole at the bottom of the straight through channel, the upper end of the bidirectional screw 11 is movably inserted into the mounting hole at the bottom of the straight through channel, and the upper end of the bidirectional screw 11 is movably passed through the top of the door frame 6 and connected to the drive transmission mechanism at its corresponding position, and the lifting sliding seat 8 is respectively screwed on the outer side walls of the upper and lower parts of the bidirectional screw 11, and the side walls of each lifting sliding seat 8 abut against the inner wall of the corresponding vertical through channel 7.

[0066] The design of the bidirectional screw 11 in the spray control mechanism has a screw structure with opposite rotation directions at the upper and lower parts. When the bidirectional screw 11 rotates, the upper and lower lifting and sliding seats 8 that are screwed together with it will move in opposite directions. This feature enables the multidirectional spray unit installed on the inner wall of the lifting and sliding seat 8 to achieve precise position adjustment. For example, for people of different heights, the position of the lifting and sliding seat 8 can be adjusted to make the multidirectional spray unit aimed at various key parts of the person's body, ensuring that the disinfectant evenly and comprehensively covers the entire body of the person, further improving the accuracy and effectiveness of disinfection. The side walls of the lifting and sliding seat 8 abut against the inner wall of the vertical through channel 7. This design plays a guiding and stabilizing role. During the lifting process, the lifting and sliding seat 8 will not shake or deflect, ensuring the stability of the multidirectional spray unit during movement, thereby making the spraying process smoother and more accurate, and avoiding uneven spraying of the agent due to shaking.

[0067] In any of the above schemes, it is preferred that the drive transmission mechanism includes a transmission pulley 12 fixedly mounted on the top of the corresponding two bidirectional screws 11, the two transmission pulleys 12 are connected by a toothed belt 13, and a drive motor 14 is installed above one of the transmission pulleys 12, and the top of the drive motor 14 is relatively fixedly connected to the door frame 6 through a motor frame 15.

[0068] The working process of the spraying position control mechanism is as follows: start the drive motor 14 of the drive transmission mechanism, the drive motor 14 can drive the two drive pulleys 12 and the toothed belt 13 to operate, and during the operation of the two drive pulleys 12, the corresponding bidirectional screw 11 can be driven to rotate. When the two bidirectional screws 11 rotate, the lifting and sliding seats 8 thereon are coordinated to achieve lifting and lowering, thereby achieving the purpose of controlling the two upper and lower relative lifting and sliding seats 8 to approach and move away from each other, and then controlling the relative positions of the two upper and lower relative multi-directional spraying units.

[0069] When the two multi-directional spray units are moved closer or further away from each other, they can effectively spray and disinfect the surrounding area of ​​the human body. The drive motor 14 in the drive transmission mechanism drives the two drive pulleys 12 and the toothed belt 13 to rotate, thereby achieving the synchronous rotation of the two bidirectional screws 11.

[0070] This synchronous transmission method ensures the consistency of the movement of the spray control mechanisms on both sides, allowing the multi-directional spray units located in different disinfection areas to adjust their positions simultaneously and to the same extent.

[0071] For example, when personnel are disinfected in the first disinfection area 4 and the second disinfection area 5 at the same time, the multi-directional spray units in the two areas can maintain the same working rhythm and position changes, ensuring the consistency and efficiency of the disinfection operations for different personnel.

[0072] The motor frame 15 relatively connects the drive motor 14 to the door frame 6, providing a stable installation foundation, reducing the vibration transmission during the operation of the motor, ensuring the stable operation of the entire drive transmission system, and thus providing a guarantee for the precise movement of the spray control mechanism, indirectly improving the stability and reliability of the disinfection operation.

[0073] With the cooperation of the first disinfection area 4 and the second disinfection area 5 with the rotation function, the following effects can be achieved: multi-directional spraying ensures full coverage: the multi-directional spraying unit is installed on the inner wall of the lifting sliding seat 8, and can spray agents on personnel from multiple directions.

[0074] All parts of the human body, such as the front, side, back, and even some easily overlooked corners, such as the armpits and the back of the legs, can be reached by disinfectants, greatly improving the comprehensiveness of disinfection and minimizing dead corners where germs remain.

[0075] Double disinfection areas enhance disinfection effect: personnel pass through the first disinfection area 4 and the second disinfection area 5 in sequence and undergo disinfection twice.

[0076] The first disinfection initially reduces the number of pathogens, and the second disinfection further kills the residual pathogens. This double disinfection mode greatly enhances the disinfection effect, reduces the possibility of residual pathogens, and can more effectively block the transmission path of the disease.

[0077] Precise positioning improves disinfection accuracy: the bidirectional screw 11 of the spray control mechanism can adjust the position of the lifting and sliding seat 8, so that the multi-directional spray unit can accurately target key parts of the body for people of different heights.

[0078] Regardless of whether the person is tall or short, the drug can be evenly and comprehensively covered, improving the accuracy of disinfection and ensuring that every person passing through can receive appropriate and effective disinfection treatment.

[0079] In any of the above schemes, it is preferred that the multi-directional spray unit includes a multi-way solenoid valve 16 fixedly mounted on the inner wall of the corresponding lifting and sliding seat 8, and a drug atomizing nozzle 17 is installed at each outlet of the multi-way solenoid valve 16, and each of the drug atomizing nozzles 17 is used to spray toward the person to be disinfected.

[0080] The multi-directional spray unit moves with the lifting sliding seat 8, which can significantly improve the disinfection effect: Adapt to different heights: the lifting sliding seat 8 can move up and down along the bidirectional screw 11, driving the multi-directional spray unit to change height.

[0081] When people of different heights enter the disinfection channel, the multi-directional spray unit can be accurately adjusted to the appropriate position, so that the agent atomization nozzle 17 can be aimed at the head, shoulders, chest, legs and other body parts of different heights, ensuring that all parts can be evenly covered by the agent, avoiding blind spots in disinfection due to height differences, and improving the targeted and comprehensive nature of disinfection.

[0082] Comprehensive disinfection coverage: The multi-way solenoid valve 16 connects to multiple atomizing nozzles 17, which can be set to different directions. During the movement of the lifting and sliding base 8, each nozzle sprays atomized agent simultaneously from multiple angles, such as the front, side, upper, and lower angles, at the person being disinfected.

[0083] The person's entire body is surrounded by the agent 360 degrees, significantly increasing the disinfection coverage area and effectively killing any pathogens that may be present in all directions, thereby enhancing the disinfection effect. Dynamic disinfection eliminates any missing areas: As the lifting and sliding base 8 moves, the multi-directional spray unit operates continuously. During the brief period a person stands in the disinfection area, the agent is continuously sprayed from different heights and angles, creating a dynamic disinfection process. Compared to fixed-position spraying, this more effectively accounts for subtle changes in the person's movements at different times, ensuring that no part of the body is missed due to posture adjustments, further improving disinfection reliability.

[0084] During the disinfection process, the person to be disinfected can lift their feet one by one to achieve spray disinfection of the soles of their feet according to the requirements specified by the staff or the machine. A foot-sensing device is installed in the standing area of ​​the first disinfection zone 4 and the second disinfection zone 5. When the disinfection person enters the disinfection zone and stands in the designated position, the sensing device detects the person's position and triggers the foot disinfection program through linkage with the multi-directional spray unit. At this time, the agent atomizing nozzle 17 located below the standing area or at a specific position is activated, and the soles of the feet of the person to be disinfected are precisely sprayed and disinfected as they are lifted one by one according to the staff's requirements.

[0085] For example, staff can set each foot to be sprayed 3-5 times according to the risk level of pathogen transmission to ensure that every part of the sole of the foot is fully exposed to the disinfectant.

[0086] Improved disinfection effect: The soles of the feet are the part that frequently contacts the outside world when people walk and are easily contaminated with various pathogens.

[0087] This method of spraying and disinfecting the soles of the feet by lifting the feet one by one can effectively compensate for the areas on the soles of the feet that may be overlooked in conventional standing disinfection, greatly improving the comprehensiveness of disinfection.

[0088] Whether it is the forefoot, heel, or side of the sole, it can be effectively disinfected under the precise spraying of medicine, further reducing the risk of pathogens spreading through the soles of the feet and enhancing the effectiveness of the entire disinfection device in disease prevention and control.

[0089] In any of the above schemes, it is preferred that the slide unit includes a translation slide 18 that is slidably engaged with the top of the ground rail 2, and the central top of the translation slide 18 is set as the first disinfection area 4 or the second disinfection area 5. A slewing bearing 19 is installed in the central concave cavity of the central top, and the rotating part of the slewing bearing 19 serves as a disinfection area for the person to be tested to stand and is equipped with an in-place sensor and an anti-slip structure installed on the top.

[0090] When the in-place sensor senses that someone is present, it can control the slewing support 19 to rotate and drive the person to be tested standing on it to rotate slowly. During the rotation process, the multi-directional spraying unit is used to complete the all-round spraying and disinfection.

[0091] When the in-position sensor senses that a person is standing on the rotating portion of the slewing support 19, the slewing support 19 drives the person to rotate slowly. During the rotation process, the multi-directional spraying unit continuously sprays the person with the agent from different directions.

[0092] This not only ensures that the front, sides, back and other conventional parts of the human body are fully disinfected, but also allows the parts of the human body that may have been blocked due to static posture, such as the inside of the arms and the back of the legs, to be fully exposed to the spraying range of the agent when the human body turns, achieving 360-degree all-round three-dimensional disinfection, further improving the comprehensiveness and thoroughness of disinfection, effectively killing germs in every corner of the human body, and reducing the risk of disease transmission.

[0093] Personnel entering the disinfection area stand on slewing bearing 19, eliminating the need for manual operation. The in-position sensor automatically detects the personnel's presence and triggers the rotation of slewing bearing 19, reducing the operator's operational burden and improving passage efficiency. Furthermore, the slow rotation speed design ensures that personnel have sufficient time to undergo comprehensive disinfection without causing discomfort such as dizziness, thus optimizing the experience of personnel passing through the disinfection passage.

[0094] The rotating portion of the slewing bearing 19 serves as a disinfection zone for personnel to stand, and is equipped with position sensors to further standardize the personnel access and disinfection process. Personnel must stand on the designated rotating portion of the slewing bearing 19 to trigger the disinfection process, ensuring that everyone entering the disinfection channel receives comprehensive disinfection according to the standard process, ensuring the consistency and stability of the disinfection effect.

[0095] In any of the above solutions, preferably, a tempered glass observation window 20 is fixedly mounted on the outer side wall of the door-type frame 6 on the outer side of each of the vertical through channels 7 .

[0096] A tempered glass observation window 20 is fixedly installed on the outer side wall of the door frame 6 outside the vertical through-channel 7. The staff can view the situation in the disinfection channel in real time through the tempered glass observation window 20; they can clearly see the disinfection process of the personnel in the first disinfection area 4 and the second disinfection area 5, including whether the multi-directional spray unit is working normally, whether the spraying of the agent covers the whole body of the personnel, and whether the personnel cooperate with the disinfection according to the prescribed procedures.

[0097] For example, during the prevention and control of infectious diseases, staff can observe the disinfection effect at any time to ensure that every person passing through is fully and effectively disinfected, and promptly discover and resolve possible problems such as equipment failure and irregular behavior of personnel, to ensure the smooth progress of disinfection work.

[0098] The tempered glass observation window 20 also makes it convenient for the staff to observe the operation of the spraying position control mechanism in the vertical through channel 7.

[0099] The user can check whether the bidirectional screw 11 rotates smoothly, whether the lifting and sliding seat 8 moves smoothly, and whether the linkage with the multi-directional spray unit is normal. This helps to promptly detect potential equipment failures and carry out maintenance and care in advance, avoiding equipment failures that affect the continuity of disinfection work and improving the reliability and stability of the entire device.

[0100] Example 2: Compared with Example 1, this example is different in that it further includes the following technical features: In any of the above schemes, preferably, an inverted U-shaped gas storage and injection chamber 21 is provided on the front and rear sides of each of the door-type frames 6, and a sealing end cover 22 is installed on the surface of each of the gas storage and injection chambers 21. The sealing end cover 22 is used to seal the interior of the gas storage and injection chamber 21 into a closed space for high-pressure gas to enter, and airflow injection gaps for injecting high-pressure and high-speed airflow into the interior of the disinfection channel are respectively opened on the inner side wall of the gas storage and injection chamber 21 along the upper part and both sides of the disinfection channel. 23. When the airflow injection slit 23 is ejected, high-speed airflow is ejected on both sides of its upper part, which can form an invisible air wall at the position of the current vertical cross-section. A connecting air pipe 24 with a valve for connecting to an external high-pressure pump device is installed on each of the sealing end covers 22. The inner ends of the connecting air pipes 24 extend to the interior of the air storage injection chamber 21 respectively; the airflow injection slits 23 are located on both sides of the first disinfection area 4 or the second disinfection area 5 and realize the isolation of the first disinfection area 4 and the second disinfection area 5, the isolation of the first disinfection area 4 from the outside, and the isolation of the second disinfection area 5 from the outside.

[0101] The air storage spray chamber 21 is provided at the front and rear sides of the door frame 6, and sprays high-pressure and high-speed air into the disinfection channel through the air flow injection slit 23. When the multi-directional spray unit sprays the agent, the air flow generated by the air wall can drive the disinfectant to spread more evenly in the disinfection area.

[0102] For example, after the agent is atomized, some of the agent may sink or gather locally due to factors such as gravity. The airflow of the air wall can blow the agent away, allowing it to more comprehensively cover all parts of the human body, further improving the comprehensiveness and effectiveness of disinfection, and ensuring that the disinfectant can fully exert its bactericidal effect.

[0103] In addition, the air wall not only helps to diffuse the agent; the high-speed airflow accelerates the air flow, so that the agent residue in the disinfection area can be discharged more quickly, avoiding excessive accumulation of agents in the disinfection area, ensuring the relative cleanliness of the disinfection area environment, preparing for subsequent personnel to enter the disinfection area, and maintaining the continuity of the disinfection effect.

[0104] Airflow injection slits 23 are located on both sides of the first disinfection zone 4 and the second disinfection zone 5. When high-pressure, high-speed air is ejected from the slits, an invisible air wall is formed in the vertical cross-section. This air wall effectively isolates the first disinfection zone 4 from the second disinfection zone 5, preventing air from mixing between the two areas and preventing bacterial aerosols and residual drug residues generated during the disinfection process in the first disinfection zone 4 from entering the second disinfection zone 5. This ensures the relative independence of each disinfection zone and reduces the risk of cross-infection.

[0105] At the same time, the air wall isolates the first disinfection area 4 from the outside, and the second disinfection area 5 from the outside, preventing the non-sterilized air from the outside from entering the disinfection area, and also preventing the drug mist, pathogens, etc. in the disinfection area from spreading to the external environment, thereby ensuring the safety of external inspectors and the surrounding environment.

[0106] By connecting to an external high-pressure pump device through a connecting air pipe 24 with a valve, the high-pressure gas pressure in the gas storage injection chamber 21 can be flexibly adjusted according to actual needs, thereby controlling the speed and intensity of the airflow ejected from the airflow injection gap 23.

[0107] During periods of high incidence of infectious diseases or in places with high requirements for disinfection and isolation, the gas pressure can be increased to enhance the isolation effect of the gas wall; in daily use or when the flow of personnel is small, the pressure can be appropriately reduced to save energy and achieve precise control of the isolation and protection intensity.

[0108] In any of the above solutions, it is preferred that the door-shaped telescopic channel 3 is formed by bending an aluminum alloy material, and the bottoms of both sides of the door-shaped telescopic channel 3 are in contact with the top surface of the ground connecting base 1.

[0109] The door-shaped telescopic channel 3 is formed by bending aluminum alloy, which is light in weight. This makes it easier for the door-shaped telescopic channel 3 to expand and contract as the two spraying and disinfecting units move along the ground track 2.

[0110] Compared with other heavier materials, it reduces the burden on the entire device during movement, reduces the requirements for the drive device, and also improves the flexibility and convenience of movement.

[0111] For example, in places where the width of the disinfection channel needs to be frequently adjusted to accommodate different personnel flows, the door-type telescopic channel 3 made of aluminum alloy can respond quickly and achieve fast and efficient channel adjustment.

[0112] The bottoms of both sides of the door-shaped telescopic channel 3 are in contact with the top surface of the ground-connecting base 1 . This installation method provides stable support for the door-shaped telescopic channel 3 during the telescopic process.

[0113] When the spraying and disinfecting unit moves, the door-shaped telescopic channel 3 will not affect the integrity of the disinfection channel due to shaking or deviation.

[0114] The design of abutting against the ground seat 1 can effectively disperse the force that the door-shaped telescopic channel 3 bears during extension and contraction, ensuring that it can remain stable in different extension and contraction states, thereby ensuring the continuity of the disinfection area and preventing the occurrence of disinfection dead corners due to the instability of the door-shaped telescopic channel 3.

[0115] In any of the above solutions, preferably, a protective frame 25 is installed on the periphery of the disinfection channel, and the bottoms of both sides of the protective frame 25 are fixed on the ground base 1.

[0116] A plurality of heat dissipation holes 26 are provided on the top and both sides of the protection frame 25 .

[0117] A protective frame 25 is installed on the periphery of the disinfection channel, and the bottoms of both sides thereof are fixed on the ground base 1, providing a physical protective barrier for the entire disinfection device.

[0118] The protective frame 25 can effectively prevent external objects from accidentally colliding with equipment in the disinfection channel, such as the spray control mechanism, the gas storage injection chamber 21, etc., to avoid damage to the equipment due to collision and affect the normal operation of the disinfection function.

[0119] For example, in places with large personnel flow and complex environment, there may be situations where the disinfection device is accidentally hit when transporting goods. The protective frame 25 can play a buffering and blocking role to ensure the stability and safety of the device.

[0120] For people passing through the disinfection channel, the protective frame 25 can prevent people from directly colliding with sharp parts or internal equipment of the disinfection device due to accidental falls or other reasons during the passage, reducing the risk of personal injury, providing people with a safer passage environment, and improving people's experience in using the disinfection device.

[0121] In addition, the plurality of heat dissipation holes 26 provided on the top and both sides of the protection frame 25 can effectively improve the heat dissipation conditions inside the disinfection device.

[0122] During the operation of the device, the drive motor 14, the high-pressure pump equipment, etc. will generate heat. If the heat cannot be dissipated in time, the performance and service life of the device may be affected.

[0123] The heat dissipation holes 26 allow external cold air to enter and form convection with the internal hot air, bringing out the heat generated by the equipment, maintaining the equipment operating within an appropriate temperature range, ensuring the stable operation of key components such as the drive transmission mechanism and the air wall injection system, and indirectly ensuring the normal realization of functions such as disinfection and isolation.

[0124] In any of the above solutions, it is preferred that a plurality of water filtering holes 27 are provided on the surface of the ground connecting base 1; and a steel structure drainage box for support and drainage is installed at the bottom of the ground connecting base 1 before use.

[0125] The coordinated use of the water filter hole 27 and the steel structure drainage box can quickly remove the accumulated water and drug residues generated during the disinfection process, reducing the contact time of these liquids with device components, such as the slide unit and the ground track 2.

[0126] This is of great significance in preventing components from rusting and corroding, reducing the probability of equipment failure due to corrosion, reducing the frequency of repair and replacement of components, reducing maintenance costs, ensuring the long-term stable operation of the disinfection device, and continuously providing reliable support for disease control and prevention work.

[0127] Specific working principle: During installation, first connect the door-shaped telescopic channel 3 with the spraying and disinfection units on both sides to form a long strip disinfection channel.

[0128] According to actual prevention and control needs, adjust the distance between the bottom slide units of the two spraying and disinfection units on the ground track 2 to drive the door-type telescopic channel 3 to extend and retract. After determining the interval prevention and control distance between the first disinfection area 4 and the second disinfection area 5, fix the slide unit.

[0129] At the same time, the protective frame 25 is installed on the periphery of the disinfection channel, and the bottoms of both sides are fixed on the ground base 1 to complete the installation and construction of the entire device.

[0130] Personnel enter the disinfection passage and stand on the rotating parts of the slewing bearing 19 of the first disinfection area 4 and the second disinfection area 5 respectively.

[0131] After the in-place sensor senses that the personnel are in place, it controls the slewing bearing 19 to drive the personnel to rotate slowly.

[0132] At this time, the drive transmission mechanism is started, and the drive motor 14 drives the transmission pulley 12 and the toothed belt 13 to operate, thereby driving the bidirectional screw 11 to rotate, causing the lifting and sliding seat 8 to move up and down, driving the multi-directional spray unit to adjust its position.

[0133] The multi-way solenoid valve 16 controls the agent atomizing nozzle 17 to spray the agent around the personnel from multiple directions to achieve preliminary disinfection.

[0134] At the same time, the external agent supply device continuously provides agents to the multi-directional spraying unit through the three-way bellows 9.

[0135] During the disinfection process, the high-pressure gas in the gas storage injection chamber 21 is ejected into the disinfection channel through the airflow injection gap 23, forming an air wall between the first disinfection area 4 and the second disinfection area 5 and at the junction of the disinfection area and the external area, which plays an isolation and protection role, preventing air mixing and the spread of pathogens between different areas.

[0136] The ventilation pipe 10 on the top of the door frame 6 works in conjunction with the external ventilation equipment to promptly discharge the medicine mist, odor and waste gas in the disinfection channel, replenish fresh air, and keep the air in the disinfection area fresh.

[0137] After the first person completes the first disinfection in the first disinfection area 4, he / she enters the second disinfection area 5 for the second disinfection. The subsequent person to be tested enters the first disinfection area 4 to start the first disinfection, ensuring the continuity of the disinfection test.

[0138] After completing the disinfection, personnel leave the disinfection channel.

[0139] During this period, the water filter holes 27 on the surface of the ground seat 1 filter the spilled medicine and accumulated water into the steel structure drainage box at the bottom, which is convenient for centralized treatment and maintains the cleanliness and safety of the disinfection channel.

[0140] The staff can monitor the disinfection process and equipment operation status in real time through the tempered glass observation window 20 to ensure that the entire disinfection operation is carried out efficiently and stably.

[0141] The entire device is powered by an external power supply, providing continuous and stable energy guarantee for the normal operation of each component.

[0142] The driving motor 14, the external medicine supply device, the ventilation device and the high-pressure pump device etc. all rely on an external power source for power.

[0143] A stable power supply ensures that the multi-directional spray unit can continuously and evenly spray disinfectants, the drive transmission mechanism accurately controls the operation of the spray position control mechanism, the ventilation equipment effectively maintains air circulation in the disinfection channel, and the air wall injection system stably forms an isolated airflow, ensuring the smooth progress of the entire disinfection and protection process, and will not affect the performance of the device due to power shortage or fluctuations.
