Description

Technical Field

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

[0002] A portal-type personnel disinfection passage is a facility for comprehensively disinfecting passing personnel. In places such as hospitals and disease control centers where personnel enter and exit frequently, the portal-type personnel disinfection passage can disinfect the entering personnel to prevent pathogens from being brought into the place and protect the health and safety of internal personnel.

[0003] Traditional disinfection passages generally consist of a frame structure, a spraying system, an induction system, etc. After retrieval, a disinfection passage is disclosed in the patent with the patent application number CN202020202698.6, and its main structure includes components such as a body, a chassis, support feet, a filter screen, a drain port, an ozone water machine, an atomizer, an induced draft fan, a pipeline, a mist discharge port, and a curtain.

[0004] It can be seen from its patent description that the above-mentioned disinfection passage is made of a profile frame combined with plastic cloth and curtain cloth, and uses an ozone water machine to make ozone water with disinfection performance by using tap water as a raw material for spraying and disinfection. Its spray port is located at the top. Such a structural setting has the following problems in the actual disinfection process: The disinfection passage releases misty ozone water through the mist discharge port of the pipeline at the top of the body for disinfection. The layout and angle of the mist discharge port are fixed, and it is difficult to ensure the overall disinfection effect. The curtain is composed of several vertically arranged curtain cloths and is tightly attached through magnetic strips. However, in the process of frequent personnel entry and exit, the magnetic strip adsorption method is easily collided and pulled, resulting in the separation of the curtain cloth, affecting the sealing performance of the curtain; at the same time, different people will constantly touch the curtain during the entry process, which is prone to cross-infection.

[0005] It can be seen that there are still some problems in the existing disinfection passage during the medicine spraying and disinfection process.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The multi-directional spray unit in the present invention sprays the agent on the personnel from multiple directions. With the dual disinfection zone design, the personnel are first disinfected in the first disinfection zone, and then disinfected in the second disinfection zone, which can comprehensively and efficiently reduce the residual bacteria. The air wall is set in the disinfection zone and at the junction with the outside, which can effectively isolate different areas and prevent the spread of bacteria and drug mist. The sliding seat cooperates with the door-type telescopic channel to flexibly adjust the width of the disinfection channel. In addition, the ventilation pipe ensures that the air in the channel is fresh, the standardized standing area and the ergonomic disinfection channel ensure that the personnel pass comfortably and the disinfection process is orderly, providing reliable protection for disease control and prevention.

[0018] 2. Efficient and comprehensive disinfection effect: The multi-directional spray unit sprays disinfectants on personnel from multiple directions. With the dual disinfection area setting, personnel are initially disinfected in the first disinfection area and then disinfected again in the second disinfection area, which greatly improves the comprehensiveness and thoroughness of disinfection, effectively reduces the residual bacteria, and significantly enhances the ability to prevent and control diseases.

[0019] 3. The spray disinfection unit can be moved on the ground track through the slide unit. Combined with the telescopic function of the door-type telescopic channel, the width of the disinfection channel and the interval control distance between the two disinfection areas can be flexibly adjusted according to the space size and personnel flow of different places, meeting diverse usage needs and having a wide range of applications.

[0020] 4. The ventilation pipe on the top of the door frame works in coordination with the external ventilation equipment to promptly discharge the drug mist, odor and exhaust gas in the disinfection channel and replenish fresh air, which not only improves the breathing environment when people pass through, but also avoids excessive accumulation of disinfectants, maintains the stability of the disinfection effect, and provides a healthy and comfortable disinfection environment for people.

[0021] 5. The first and second disinfection areas are clearly defined, as well as the standing area on the top of the slide unit. The design of using the slewing bearing to drive personnel to rotate for all-round disinfection standardizes the personnel's passage and disinfection process, ensures the consistency of the disinfection effect, and improves the efficiency and quality of the overall disinfection work.

[0022] 6. The water filter holes on the surface of the ground seat cooperate with the steel structure drainage box at the bottom to timely remove the accumulated water and drug residues generated during the disinfection process, reduce the corrosion risk of equipment components, and extend the service life of the equipment; the protective frame provides physical protection for the device to prevent external collisions from damaging the equipment, ensure the long-term stable operation of the device, and reduce maintenance costs.

Specific implementation method

[0042] The following will describe the embodiments of the technical solution of the present invention in detail with reference to the accompanying drawings.

[0043] The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0044] The specific structure of the present invention is as follows Figure 1-Figure 15 As shown in .

[0045] Example 1: A safe door-type medicine spraying device for disease control and prevention, comprising a fixedly installed ground-connecting seat 1, with ground-connecting tracks 2 integrally formed on the tops of the left and right sides of the ground-connecting seat 1, and two spraying and disinfecting units spaced apart along the length direction of the ground-connecting seat 1, the bottoms of the two spraying and disinfecting units are slidably mounted on the two ground-connecting tracks 2 through the translational slides 18 at the bottoms thereof, the two spraying and disinfecting units are connected through 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 personnel to pass through, and a first disinfection area 4 and a second disinfection area 5 are respectively arranged inside the front spraying and disinfecting unit and inside the rear spraying and disinfecting unit.

[0046] The entire safety door-type agent spraying device is fixedly installed with a ground seat 1. Before installation, the door-type telescopic channel 3 is first connected and fixedly connected with the spraying and disinfection units on both sides. At this time, a long strip of disinfection channel is formed inside the three. The telescopic door-type telescopic channel 3 can be controlled to a suitable length as needed, so as to control the distance between the two spraying and disinfection units, and finally achieve the purpose of controlling the 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 the disinfection inspection of two people is carried out at the same time, and the same person to be tested completes the first disinfection in the first disinfection area 4, and the second disinfection is carried out 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 to 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.

[0047] 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 expand and contract. After expansion and contraction, the fixation of the two translation slides 18 ensures the relative stability of the newly formed channel.

[0048] During the process of personnel disinfection in the first disinfection area 4 and the second disinfection area 5, the spray disinfection unit at the corresponding position 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 effectively isolate the internal personnel from the external inspection personnel, ensure the relative independence of the first disinfection area 4 and the second disinfection area 5, and at the same time, in the process of disinfection, timely cooperate with the external ventilation equipment to discharge the spray mist and airflow 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.

[0049] 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 position control mechanism is installed in each of the vertical through channels 7, and the lower end of the spraying position control mechanism is movably inserted in the bottom mounting hole of the vertical through channel 7, and the top of the spraying position control mechanism is movably extended to the top of the door-type frame 6 and connected to the corresponding driving transmission mechanism, and multi-directional spray units are installed on the inner side walls of the two lifting and sliding seats 8 of the spraying position control mechanism, and each of the multi-directional spray units is composed of The three-way bellows 9 with a valve installed in the vertical through-channel 7 outside the spray control mechanism is connected to the external medicine supply equipment. 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. 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 installed on the top of the corresponding translation slide 18 below them. 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.

[0050] A multi-directional spray unit is installed on the inner wall of the two lifting and sliding seats 8 of the spray control mechanism, which can spray the agent on the passing personnel from multiple directions to ensure that all parts of the body can be exposed to the disinfectant, thereby improving the comprehensiveness and effectiveness of the disinfection. When the first disinfection area 4 and the second disinfection area 5 are working at the same time, the multi-directional spray unit can quickly disinfect the whole body of the person standing therein to achieve efficient sterilization.

[0051] Each multi-directional spray unit is connected to the external agent supply equipment through a three-way bellows 9 installed in the vertical through-channel 7, ensuring a continuous and stable supply of agents 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 agents. Whether the disinfection operation is carried out in the first disinfection area 4 or the second disinfection area 5, it can ensure sufficient supply of agents and maintain a stable disinfection effect. The first disinfection area 4 and the second disinfection area 5 are respectively provided inside the spray disinfection unit on the front and rear sides. 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.

[0052] 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 direction of the ground seat 1. This design can flexibly adjust the width of the disinfection channel according to actual use needs to adapt to different places and personnel flow conditions.

[0053] 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.

[0054] When it is necessary to control the distance between the 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 stage, thereby driving the door-shaped telescopic channel 3 in the middle to expand and contract. 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 through the door-shaped telescopic channel 3. When the spray disinfection unit moves, the door-shaped telescopic channel 3 can be expanded and contracted accordingly, always maintaining the integrity of the disinfection channel, which does not affect the passage of personnel, and can ensure the continuity of the disinfection area and prevent the occurrence of disinfection dead corners.

[0055] Before installation, the door-type telescopic channel 3 is connected to the spraying and disinfection units on both sides, and a long strip disinfection channel is formed inside the three. According to the prevention and control needs, the door-type telescopic channel 3 can be controlled to be extended to a suitable length, so as to flexibly adjust the distance between the two spraying and disinfection units, and realize the precise control of the distance between the first disinfection area 4 and the second disinfection area 5. The ventilation pipe 10 is installed in the middle of the top of the door frame 6, and its bottom is connected to the disinfection channel inside the door frame 6, and the top is connected to the external ventilation equipment through a pipeline.

[0056] 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 timely discharge the drug mist and odor generated during the disinfection process and improve the breathing environment when people pass through; on the other hand, it can avoid excessive accumulation of disinfectants in the channel and ensure the continuity and stability of the disinfection effect.

[0057] When the first disinfection area 4 and the second disinfection area 5 are simultaneously carrying out personnel disinfection operations, the ventilation equipment can promptly discharge the mist and airflow generated by the internal spraying to the outside, maintain the relative cleanliness of the air in the two disinfection areas, and reduce the risk of cross infection. The two spray disinfection units and the door-type telescopic channel 3 together form a disinfection channel for personnel to pass through. The height and width of the channel should be designed in accordance with ergonomics to ensure that personnel can pass through normally and comfortably.

[0058] The first disinfection area 4 and the second disinfection area 5 set in the passage provide space for personnel to receive comprehensive disinfection during the passage, ensuring that personnel are effectively disinfected before entering a specific place. When the flow of personnel is large, the channel 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 channel, 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.

[0059] 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.

[0060] When the person to be tested enters the disinfection passage inside the door-type, the sensor configured on the top of the door-type 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.

[0061] During the disinfection process, the operation of the spraying position control mechanism on both sides can be controlled by controlling the operation of the driving transmission mechanism. During the operation of the spraying position control mechanism, the lifting and sliding seat 8 can be driven to move relatively close or relatively far away. In this process, the corresponding three-way corrugated pipe 9 can be driven to expand and contract. At the same time, the multi-directional spraying units can be controlled to rise and fall relative to or opposite to each other. During the lifting process, the spraying of aerosol medicine to the personnel can be maintained. Therefore, the comprehensiveness of the disinfection position of the personnel can be guaranteed, and the spraying disinfection effect can be improved.

[0062] After the personnel have finished disinfecting the first disinfection area 4, they can continue to move forward to the second disinfection area 5, and then quickly complete the disinfection in the second disinfection area 5. The disinfection of the first disinfection area 4 is not affected during the disinfection of the second disinfection area 5, thus ensuring the efficiency and effect 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.

[0063] In addition, when disinfecting in the first disinfection area 4, two multi-directional spray units can be used to disinfect from the middle to the upper and lower parts relatively far away from each other, so as to first disinfect the human body's trunk and then disinfect the upper and lower limbs, head and feet; when disinfecting in the second disinfection area 5, two multi-directional spray units can be used to disinfect from the upper and lower parts relatively close to the middle, so as to first disinfect the upper and lower limbs, head and feet and then disinfect the trunk. The combination of the two disinfection methods improves the comprehensiveness and efficiency of disinfection.

[0064] In any of the above schemes, it is preferred that the spraying control mechanism includes a bidirectional lead screw 11 vertically installed in the vertical through channel 7, the upper and lower lead screws of the bidirectional lead screw 11 rotate in opposite directions, the lower end of the bidirectional lead screw 11 is movably inserted into the mounting hole at the bottom of the straight through channel, the upper end of the bidirectional lead screw 11 movably passes through the top of the door frame 6 and is connected to the drive transmission mechanism at its corresponding position, the lifting and sliding seats 8 are respectively screwed on the outer side walls of the upper and lower parts of the bidirectional lead screw 11, and the side walls of each lifting and sliding seat 8 abut against the inner wall of the corresponding vertical through channel 7.

[0065] The design of the bidirectional lead screw 11 in the spray control mechanism has a lead screw structure with opposite rotation directions at the upper and lower parts. When the bidirectional lead screw 11 rotates, the upper and lower lifting and sliding seats 8 that are screwed therewith will move in opposite directions. This feature enables the multi-directional 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 aim the multi-directional spray unit at various key parts of the person's body, ensuring that the disinfectant evenly and comprehensively covers the person's body, further improving the accuracy and effect of disinfection. The side wall of the lifting and sliding seat 8 abuts 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 deviate, ensuring the stability of the multi-directional spray unit during movement, thereby making the spraying process smoother and more accurate, and avoiding uneven spraying of the agent due to shaking.

[0066] In any of the above schemes, it is preferred that the drive transmission mechanism includes a drive pulley 12 fixedly mounted on the top of the two corresponding bidirectional screws 11, the two drive pulleys 12 are connected by a toothed belt 13, a drive motor 14 is mounted above one of the drive pulleys 12, and the top of the drive motor 14 is relatively fixedly connected to the door frame 6 through a motor frame 15.

[0067] The working process of the spraying 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 lead screws 11 can be driven to rotate, and when the two bidirectional lead 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 lifting and sliding seats 8 relative to each other to move closer and farther from each other, and then controlling the relative positions of the two multi-directional spray units relative to each other.

[0068] When the two multi-directional spray units are close to or far away from each other, they can effectively complete the spray disinfection around the human body. The drive motor 14 in the drive transmission mechanism drives the two drive pulleys 12 and the toothed belt 13 to operate, thereby realizing the synchronous rotation of the two bidirectional screws 11.

[0069] This synchronous transmission method ensures the consistency of the movement of the spray control mechanisms on both sides, so that the multi-directional spray units located in different disinfection areas can be adjusted in position at the same time and with the same amplitude.

[0070] For example, when the first disinfection area 4 and the second disinfection area 5 are disinfecting personnel at the same time, the multi-directional spraying 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.

[0071] The motor frame 15 relatively connects the drive motor 14 and 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 further providing guarantee for the precise movement of the spraying control mechanism, indirectly improving the stability and reliability of the disinfection operation.

[0072] 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 and sliding seat 8, and can spray agents on personnel from multiple directions.

[0073] 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 the dead corners where germs remain.

[0074] Double disinfection area to enhance disinfection effect: personnel pass through the first disinfection area 4 and the second disinfection area 5 in turn, and undergo two disinfection.

[0075] The first disinfection initially reduces the number of germs, and the second disinfection further kills the remaining germs. This double disinfection mode greatly enhances the disinfection effect, reduces the possibility of residual germs, and can more effectively block the path of disease transmission.

[0076] Precise positioning improves disinfection accuracy: The two-way lead 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.

[0077] Whether the person is tall or short, the agent 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.

[0078] 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 medicine atomizing nozzle 17 is installed at each outlet of the multi-way solenoid valve 16, and each of the medicine atomizing nozzles 17 is used to spray toward the person to be disinfected.

[0079] The multi-directional spray unit moves with the lifting and sliding seat 8, which can significantly improve the disinfection effect: Adapt to different heights: the lifting and sliding seat 8 can move up and down along the bidirectional screw 11, driving the multi-directional spray unit to change height.

[0080] 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 body parts of different heights such as the head, shoulders, chest, legs, etc., to ensure that all parts can be evenly covered by the agent, avoiding blind spots in disinfection due to height differences, and improving the pertinence and comprehensiveness of disinfection.

[0081] All-round disinfection coverage: The multi-way solenoid valve 16 is connected to multiple drug atomizing nozzles 17, and these nozzles can be set to different directions. During the movement of the lifting and sliding seat 8, each nozzle sprays atomized drugs to the person to be disinfected from multiple angles, such as the front, side, obliquely above, obliquely below, etc.

[0082] The personnel are surrounded by the agent within a 360-degree range, which greatly increases the coverage of disinfection, effectively kills possible germs in all directions, and enhances the disinfection effect. Dynamic disinfection without omissions: As the lifting and sliding seat 8 moves, the multi-directional spray unit continues to work. During the short time when the personnel stand in the disinfection area, the agent is continuously sprayed from different heights and angles to form a dynamic disinfection process. Compared with spraying in a fixed position, this can more effectively handle the subtle changes in the movements of various parts of the personnel's body at different times, ensuring that no part is missed due to the adjustment of the personnel's posture, and further improving the reliability of disinfection.

[0083] During the disinfection process, the person to be disinfected can lift his feet one by one to spray and disinfect the soles of his feet according to the requirements specified by the staff or the machine. A sole sensing device is configured in the standing area of ​​the first disinfection area 4 and the second disinfection area 5. When the disinfection personnel enter the disinfection area and stand in the designated position, the sensing device detects that the personnel are in place and triggers the sole 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 started, and according to the requirements of the staff, the soles of the feet of the person to be disinfected are lifted one by one for precise spraying and disinfection.

[0084] For example, staff can set each foot to be sprayed 3-5 times according to the risk of germ transmission to ensure that all parts of the sole of the foot can be fully exposed to the disinfectant.

[0085] 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 germs.

[0086] This method of spraying and disinfecting the soles of the feet by lifting the feet one by one can effectively make up for the soles of the feet that may be ignored in conventional standing disinfection, greatly improving the comprehensiveness of disinfection.

[0087] Whether it is the forefoot, heel, or side of the sole, it can be effectively disinfected under the precise spraying of the agent, further reducing the risk of germs spreading through the soles of the feet and enhancing the effectiveness of the entire disinfection device in disease prevention and control.

[0088] In any of the above schemes, it is preferred that the slide unit includes a translation slide 18 slidably engaged with the top of the ground track 2, the center top of the translation slide 18 is set as the first disinfection area 4 or the second disinfection area 5, and a slewing bearing 19 is installed in the center concave cavity of the center top, 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.

[0089] When the in-place sensor senses someone, it can control the slewing bearing 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.

[0090] When the in-position sensor senses that a person is standing on the rotating part of the slewing bearing 19, the slewing bearing 19 drives the person to rotate slowly. During the rotation process, the multi-directional spraying unit continues to spray the person with medicine from different directions.

[0091] This not only ensures that the front, side, back and other conventional parts of the body are fully disinfected, but also allows the parts of the 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 within the spraying range when the body is turning, achieving 360-degree all-round three-dimensional disinfection, further improving the comprehensiveness and thoroughness of disinfection, effectively killing germs in every corner of the body, and reducing the risk of disease transmission.

[0092] People enter the disinfection area and stand on the slewing bearing 19. No manual operation is required. The in-place sensor automatically recognizes the position of the person and triggers the rotation of the slewing bearing 19, which reduces the operating burden of the personnel and improves the passage efficiency. At the same time, the slow rotation speed design can ensure that the personnel have enough time to receive comprehensive disinfection without causing discomfort such as dizziness, thus optimizing the experience of personnel passing through the disinfection channel.

[0093] The rotating part of the slewing bearing 19 is used as a disinfection area for the personnel to be tested to stand, and a position sensor is configured to further standardize the personnel's passage and disinfection process. The personnel must stand on the designated rotating part of the slewing bearing 19 to trigger the disinfection procedure, ensuring that everyone entering the disinfection channel can receive comprehensive disinfection according to the standard process, ensuring the consistency and stability of the disinfection effect.

[0094] In any of the above solutions, preferably, a tempered glass observation window 20 is fixedly installed on the outer side wall of the door-type frame 6 outside each of the vertical through passages 7.

[0095] A tempered glass observation window 20 is fixedly installed on the outer side wall of the door frame 6 outside the vertical through passage 7. The staff can view the situation in the disinfection passage 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 spray covers the whole body of the personnel, and whether the personnel cooperate with the disinfection according to the prescribed process.

[0096] 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 solve possible problems such as equipment failure and irregular behavior of personnel, so as to ensure the smooth progress of disinfection work.

[0097] The tempered glass observation window 20 also facilitates the staff to observe the operation of the spraying control mechanism in the vertical through channel 7.

[0098] You can check whether the two-way 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 timely discover potential equipment failures, perform maintenance and care in advance, avoid affecting the continuity of disinfection work due to equipment failure, and improve the reliability and stability of the entire device.

[0099] Example 2: Compared with Example 1, this embodiment is different in that it also includes the following technical features: In any of the above schemes, preferably, an inverted U-shaped gas storage spray 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 spray chambers 21. The sealing end cover 22 is used to seal the interior of the gas storage spray chamber 21 into a closed space for high-pressure gas to enter, and air flow spray holes for spraying high-pressure and high-speed airflow into the interior of the disinfection channel are respectively provided on the inner side wall of the gas storage spray chamber 21 along the upper part and both sides of the disinfection channel. The air jet gap 23 is formed. When the air jet gap 23 is ejected, high-speed air jets are 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 ejection chamber 21 respectively; the air jet gaps 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.

[0100] The air storage spray chamber 21 is arranged at the front and rear sides of the door frame 6, and sprays high-pressure and high-speed airflow into the disinfection channel through the airflow spray gap 23. When the multi-directional spray unit sprays the agent, the airflow generated by the air wall can drive the disinfectant to spread more evenly in the disinfection area.

[0101] 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 fully 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.

[0102] In addition, the air wall not only helps the diffusion of the agent; the high-speed airflow accelerates the air flow, so that the agent residue in the disinfection area can be discharged faster, avoiding excessive accumulation of agents in the disinfection area, ensuring the relative cleanliness of the disinfection area, preparing for subsequent personnel to enter the disinfection area, and maintaining the continuity of the disinfection effect.

[0103] The air jet gap 23 is located on both sides of the first disinfection area 4 and the second disinfection area 5. When the high-pressure and high-speed airflow is ejected from the gap, an invisible air wall is formed in the vertical section. This air wall effectively isolates the first disinfection area 4 from the second disinfection area 5, prevents the mixing of air between the two areas, and prevents the bacterial aerosol and drug residues generated during the disinfection process of the first disinfection area 4 from entering the second disinfection area 5, ensuring the relative independence of each disinfection area and reducing the risk of cross infection.

[0104] 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, germs, etc. in the disinfection area from spreading to the external environment, ensuring the safety of external inspectors and the surrounding environment.

[0105] The connecting air pipe 24 with a valve is connected to an external high-pressure pump device, and 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.

[0106] During the 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 people is small, the pressure can be appropriately reduced to save energy and achieve precise control of the isolation and protection intensity.

[0107] In any of the above solutions, preferably, the door-shaped telescopic passage 3 is formed by bending an aluminum alloy material, and the bottoms of both sides of the door-shaped telescopic passage 3 are in contact with the top surface of the ground-connecting seat 1.

[0108] The door-shaped telescopic channel 3 is made of 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 disinfection units move along the ground track 2.

[0109] Compared to other heavier materials, it reduces the burden on the overall device when moving, reduces the requirements for the drive device, and also improves the flexibility and convenience of movement.

[0110] 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.

[0111] 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.

[0112] When the spraying and disinfection unit moves, the door-type telescopic channel 3 will not affect the integrity of the disinfection channel due to shaking or deviation.

[0113] The design of abutting against the ground connection base 1 can effectively disperse the force borne by the door-type telescopic channel 3 during telescopic movement, ensuring that it can remain stable in different telescopic states, thereby ensuring the continuity of the disinfection area and preventing the occurrence of disinfection dead corners due to the instability of the door-type telescopic channel 3.

[0114] 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 connection seat 1.

[0115] Several heat dissipation holes 26 are provided on the top and both sides of the protection frame 25.

[0116] A protective frame 25 is installed on the periphery of the disinfection channel, and the bottoms of both sides are fixed on the ground seat 1, providing a physical protective barrier for the entire disinfection device.

[0117] The protective frame 25 can effectively prevent external objects from accidentally colliding with the equipment in the disinfection channel, such as the spray control mechanism, the gas storage spray chamber 21, etc., to avoid damage to the equipment due to collision and affect the normal operation of the disinfection function.

[0118] For example, in places with large flow of people and complex environment, there may be a situation where the disinfection device is accidentally hit when carrying goods. The protective frame 25 can play a buffering and blocking role to ensure the stability and safety of the device.

[0119] For personnel passing through the disinfection channel, the protective frame 25 can prevent personnel from directly colliding with sharp parts or internal equipment of the disinfection device due to accidental falls during the passage, thereby reducing the risk of injury to personnel, providing a safer passage environment for personnel, and improving the experience of personnel using the disinfection device.

[0120] 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.

[0121] During the operation of the device, the drive motor 14, high-pressure pump equipment, etc. will generate heat. If the heat cannot be dissipated in time, the performance and service life of the equipment may be affected.

[0122] The heat dissipation holes 26 allow the outside cold air to enter and form convection with the internal hot air, taking out the heat generated by the equipment, maintaining the equipment running within a suitable 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.

[0123] In any of the above schemes, it is preferred that a plurality of water filtering holes 27 are provided on the surface of the ground connection seat 1; and a steel structure drainage box for support and drainage is installed at the bottom of the ground connection seat 1 before use.

[0124] The use of the water filter hole 27 and the steel structure drainage box can quickly remove the accumulated water and drug residues produced during the disinfection process, and reduce the contact time between these liquids and device components, such as the slide unit and the ground track 2.

[0125] This is of great significance for preventing parts from rusting and corrosion, reducing the probability of equipment failure due to corrosion, reducing the frequency of repair and replacement of parts, reducing maintenance costs, ensuring the long-term stable operation of the disinfection device, and continuously providing reliable support for disease control and prevention work.

[0126] 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.

[0127] According to the actual prevention and control needs, adjust the distance between the bottom slide units of the two spray 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.

[0128] 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 seat 1 to complete the installation of the entire device.

[0129] People enter the disinfection channel and stand on the rotating parts of the slewing bearing 19 of the first disinfection area 4 and the second disinfection area 5 respectively.

[0130] After the in-place sensor senses that the person is in place, it controls the slewing bearing 19 to drive the person to rotate slowly.

[0131] At this time, the drive transmission mechanism is started, and the drive motor 14 drives the drive pulley 12 and the toothed belt 13 to operate, thereby driving the bidirectional lead screw 11 to rotate, so that the lifting and sliding seat 8 moves up and down, driving the multi-directional spray unit to adjust its position.

[0132] 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.

[0133] At the same time, the external agent supply device continues to provide agents to the multi-directional spray unit through the three-way bellows 9.

[0134] During the disinfection process, the high-pressure gas in the gas storage spray chamber 21 is sprayed into the disinfection channel through the airflow spray 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 to prevent air mixing and germ transmission between different areas.

[0135] The ventilation pipe 10 on the top of the door frame 6 works in conjunction with the external ventilation equipment to promptly discharge the drug mist, odor and waste gas in the disinfection channel, replenish fresh air, and keep the air in the disinfection area fresh.

[0136] 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 personnel to be tested enter the first disinfection area 4 to start the first disinfection, ensuring the continuity of the disinfection test.

[0137] After completing the disinfection, the personnel left the disinfection channel.

[0138] 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.

[0139] 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.

[0140] The entire device is powered by an external power supply, providing continuous and stable energy guarantee for the normal operation of each component.

[0141] 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.

[0142] Stable power supply ensures that the multi-directional spray unit can spray disinfectants continuously and evenly, the drive transmission mechanism accurately controls the operation of the spray control mechanism, the ventilation equipment effectively maintains the air circulation in the disinfection channel, and the air wall injection system stably forms an isolated airflow to ensure the smooth progress of the entire disinfection and protection process, and the performance of the device will not be affected by power shortage or fluctuations.
