本发明的有益效果：The beneficial effects of the present invention:
1、本发明人员密集区对有害细菌及病毒的防护方法及装置，其通过设置供单人独处的封闭间，且进入封闭间的空气和排出封闭间的空气都经过了除菌装置处理，使得进入封闭间的空气和排出封闭间的空气都是安全的空气。1. The method and device for protecting harmful bacteria and viruses in densely populated areas of the present invention is achieved by setting up a closed room for a single person to live alone, and the air entering the closed room and the air discharged from the closed room are processed by the sterilization device, so that The air entering the enclosure and the air exiting the enclosure are safe air.
2、本发明人员密集区对有害细菌及病毒防护方法及装置，其通过把人员放置在仅容纳1人的狭小的封闭隔离空间内，既解决了人员众多与场所面积有限的矛盾问题，又解决了人们隔离防护的可靠性问题。2. The method and device for preventing harmful bacteria and viruses in the densely populated area of the present invention not only solves the contradiction between the large number of people and the limited area of the place, but also by placing the personnel in a narrow and isolated space that only accommodates one person. This solves the reliability problem of people's isolation protection.
3、本发明人员密集区对有害细菌及病毒的防护方法及装置，其设置的负压吸附腔位于封闭间内人员的口鼻附近，封闭间内的人可以直接在负压吸附腔内咳嗽、打喷嚏，这种情况下封闭间内人员产生的气溶胶及飞沫是处在负压吸附腔内，飞沫和气溶胶能快速的被负压气流吸走，从而能避免咳嗽、打喷嚏等喷溅的飞沫及气溶胶向周围扩散。并且在人员正常呼吸、说话等情况下产生的飞沫及气溶胶，这时的产生的飞沫和气溶胶的速度不像咳嗽、打喷嚏时那样快，人员的口鼻可以处在负压吸附腔外离负压吸附腔的吸气口较近的位置，这时负压气流同样能将人口鼻产生的飞沫及气溶胶快速的吸入负压吸 附腔。因此，不管在咳嗽、打喷嚏产生的呼气强气流或正常说话、呼吸产生的呼气弱气流情况下，本发明都能使得人员产出的气溶胶及飞沫能被快速的吸走排出封闭间，避免了气溶胶及飞沫在封闭间内停留，使得当一个人使用完封闭间离开后，封闭间内不会残留该人员产生的气溶胶和飞沫，使下一个人可以继续安全的使用该封闭间。3. The method and device for the protection against harmful bacteria and viruses in the densely populated area of the present invention is provided with a negative pressure adsorption cavity located near the mouth and nose of the person in the enclosed room, and the person in the enclosed room can directly cough in the negative pressure adsorption cavity. Sneezing, in this case, the aerosols and droplets produced by the people in the enclosed room are in the negative pressure adsorption cavity, and the droplets and aerosols can be quickly sucked away by the negative pressure airflow, so as to avoid coughing, sneezing, etc. The splashed droplets and aerosols spread to the surroundings. In addition, the droplets and aerosols that are produced when the person breathes and speaks normally, the droplets and aerosols produced at this time are not as fast as when coughing or sneezing, and the mouth and nose of the person can be in the negative pressure adsorption cavity Outside the position closer to the suction port of the negative pressure adsorption cavity, the negative pressure airflow can also quickly suck the droplets and aerosols generated by the human nose into the negative pressure adsorption cavity. Therefore, regardless of the strong exhalation airflow generated by coughing and sneezing or the weak exhalation airflow generated by normal speech and breathing, the present invention can enable the aerosol and droplets produced by personnel to be quickly sucked away and closed. It prevents aerosols and droplets from staying in the closed room, so that when a person leaves the closed room after using the closed room, the aerosol and droplets produced by the person will not remain in the closed room, so that the next person can continue to be safe. Use the enclosed room.
4、本发明人员密集区对有害细菌及病毒的防护方法及装置，在单人独处的封闭间内，人员不必戴口罩，且封闭间内气流通畅，呼吸舒适性好，解决了长时间佩戴口罩容易造成不舒适的技术问题。4. The protection method and device of the present invention against harmful bacteria and viruses in the densely populated area of the present invention. In the enclosed room where one person is alone, the person does not need to wear a mask, and the airflow in the enclosed room is smooth, and the breathing comfort is good, which solves the problem of wearing masks for a long time. It is easy to cause uncomfortable technical problems.
5、传统技术中提高抽风换气效果的方法是增加风机的功率，提高负压气流的流量、流速。但是对于本发明中供单人独处的封闭间，由于封闭间体积狭小，若在狭小封闭间内采用大流量高流速的强气流抽吸空气，强气流本身会给人产生不适感，并且强气流还会产生风噪其它使人不舒适的感觉。本发明通过在封闭间内再设置负压吸附腔，因负压吸附腔离人的口鼻近，或者头部还可直接处在负压吸附腔内，使得不需要强气流即能吸走人员产生的飞沫及气溶胶，解决了弱气流不能在人员咳嗽、打喷嚏情况下快速吸走其产生的飞沫及气溶胶的问题，因此本发明能让封闭间内的人员处在自然的微风状态下并快速地吸走人员产生的气溶胶及飞沫，能给人舒适的感觉。5. In the traditional technology, the method to improve the ventilation effect is to increase the power of the fan and increase the flow and velocity of the negative pressure airflow. However, for the enclosed room for a single person in the present invention, due to the small size of the enclosed room, if a strong airflow with a large flow rate and a high velocity is used to suck air in a narrow enclosed room, the strong airflow itself will cause discomfort to people, and the strong airflow It also produces wind noise and other uncomfortable feelings. In the present invention, a negative pressure adsorption cavity is arranged in the closed room. Because the negative pressure adsorption cavity is close to the mouth and nose of the person, or the head can be directly located in the negative pressure adsorption cavity, the person can be sucked away without strong air flow. The droplets and aerosols produced solve the problem that the weak airflow cannot quickly absorb the droplets and aerosols generated by the person in the case of coughing or sneezing. Therefore, the present invention allows the persons in the enclosed room to be in a natural breeze It can quickly absorb the aerosols and droplets produced by the personnel under the state, which can give people a comfortable feeling.
6、本发明人员密集区对有害细菌及病毒的防护方法及装置，设置进气口和排气管使封闭间内的空气与封闭间外的空气进行交换、流动。相对于采用“内、内空气循环”的空调、空气净化器等而言，本发明中的封闭间内时刻有外部新风进入，能给提高封闭间内人员使用体验的舒适感。6. The method and device for protecting harmful bacteria and viruses in the densely populated area of the present invention are provided with air inlets and exhaust pipes so that the air in the enclosed room can be exchanged and flowed with the air outside the enclosed room. Compared with air conditioners and air purifiers that adopt "internal and internal air circulation", the enclosed room in the present invention always has external fresh air entering, which can improve the comfort of the people in the enclosed room.
7、本发明人员密集区对有害细菌及病毒的防护方法及装置，其利用封闭间将外界空气隔离，避免了外界气流造成封闭间内的气流紊乱，解决了外界气流影响负压吸附腔收集人员产生的飞沫及气溶胶的问题。7. The protection method and device of the present invention against harmful bacteria and viruses in the densely populated area of the present invention uses a closed room to isolate the outside air, avoiding the turbulence of the air flow in the closed room caused by the outside air flow, and solving the problem of the outside air flow affecting the negative pressure adsorption chamber to collect personnel The problem of droplets and aerosols.
8、本发明人员密集区对有害细菌及病毒的防护方法及装置，既能让人们获得可靠的防交叉感染的防护效果，又获得很舒适的使用体验感，适用于在办公室、会议室及餐厅等人员密集地推广使用，能很好的解决人员密集区的交 叉感染问题，应用前景好。8. The protection method and device for harmful bacteria and viruses in densely populated areas of the present invention can not only allow people to obtain reliable protection against cross-infection, but also obtain a very comfortable use experience, which is suitable for use in offices, conference rooms and restaurants.

The closed room is provided with a door 2, an air inlet 3 and an exhaust pipe 4, and the enclosed room The negative pressure adsorption cavity 5 connected with the exhaust pipe is located near the mouth and nose of a person. Connect the exhaust pipe 4 to the fan when in use. In this embodiment, the negative pressure adsorption cavity is located in front of the mouth and nose of a person. The specific negative pressure adsorption cavity may be a rectangular parallelepiped cavity with an air inlet on the side facing the human face, and its structure is shown in FIG. 2. The negative pressure adsorption cavity is arranged in front of the mouth and nose of the person, and the airflow in the negative pressure adsorption cavity is not affected by the airflow outside the enclosed room, and can suck away the droplets and aerosols generated by the person more quickly and thoroughly.
当然在不同实施例中，负压吸附腔的吸气口还可包围在人的口鼻外，这种情况下负压吸附腔5可以由位于头部前侧、头部上侧、头部左侧和头部右侧的侧板连接组成，人员的头部及手部可以在负压吸附腔中活动，其结构如图3所示，人头部位于负压吸附腔内，负压吸附腔内的气流不受封闭间外的气流影响，也能实现快速、彻底的将人员产生的飞沫、气溶胶吸走。当然本 实施情况中的头部前侧、头部左侧和头部右侧的侧板还可由封闭间的侧壁替换。Of course, in different embodiments, the suction port of the negative pressure adsorption cavity can also be enclosed outside the human mouth and nose. In this case, the negative pressure adsorption cavity 5 can be located on the front side of the head, the upper side of the head, and the left side of the head. The side and the side plate on the right side of the head are connected. The head and hands of the person can move in the negative pressure adsorption chamber. The structure is shown in Figure 3. The human head is located in the negative pressure adsorption chamber. The air flow inside is not affected by the air flow outside the enclosed room, and it can also quickly and completely suck away the droplets and aerosols generated by the personnel. Of course, the side panels on the front, left and right sides of the head in this embodiment can also be replaced by side walls of the enclosed room.
所述人员密集区对有害细菌及病毒的防护装置还包括用于消除进气口吸入的空气中含有的病毒及有害病菌的第一除菌装置6和用于消除排气管排出空气中含有的病毒及有害病菌的第二除菌装置7。The protective device for harmful bacteria and viruses in the densely populated area also includes a first sterilization device 6 for eliminating viruses and harmful bacteria contained in the air inhaled by the air inlet and a first sterilization device 6 for eliminating harmful bacteria and harmful bacteria in the air discharged from the exhaust pipe. The second sterilization device for viruses and harmful bacteria7.
本实施例中人员密集区对有害细菌及病毒的防护方法及装置，其通过设置供单人独处的封闭间，且进入封闭间的空气和排出封闭间的空气都经过了除菌装置处理，使得进入封闭间的空气和排出封闭间的空气都是安全的空气。In this embodiment, the method and device for protecting harmful bacteria and viruses in densely populated areas is achieved by setting up a closed room for a single person to live alone, and the air entering the closed room and the air discharged from the closed room are processed by the sterilization device, so that The air entering the enclosure and the air exiting the enclosure are safe air.
不仅如此，本实施例中设置的负压吸附腔位于封闭间内人员的口鼻附近，封闭间内的人可以直接在负压吸附腔内咳嗽、打喷嚏，这种情况下封闭间内人员产生的气溶胶及飞沫是处在负压吸附腔内，飞沫和气溶胶能快速的被负压气流吸走，从而能避免咳嗽、打喷嚏等喷溅的飞沫及气溶胶向周围扩散。并且在人员正常呼吸、说话等情况下产生的飞沫及气溶胶，这时的产生的飞沫和气溶胶的速度不像咳嗽、打喷嚏时那样快，人员的口鼻可以处在负压吸附腔外离负压吸附腔的吸气口较近的位置，这时负压气流同样能将人口鼻产生的飞沫及气溶胶快速的吸入负压吸附腔。因此，不管在咳嗽、打喷嚏产生的强气流或正常说话、呼吸产生的弱气流情况下，本发明都能使得人员产出的气溶胶及飞沫能被快速的吸走排出封闭间，避免了气溶胶及飞沫在封闭间内停留，使得当一个人使用完封闭间离开后，封闭间内不会残留该人员产生的气溶胶和飞沫，使下一个人可以继续安全的使用该封闭间。Not only that, the negative pressure adsorption cavity set in this embodiment is located near the mouth and nose of the person in the enclosed room, and the person in the enclosed room can directly cough or sneeze in the negative pressure adsorption cavity. In this case, the person in the enclosed room produces The aerosols and droplets are in the negative pressure adsorption cavity, and the droplets and aerosols can be quickly sucked away by the negative pressure airflow, so as to prevent coughing, sneezing and other splashing droplets and aerosols from spreading to the surrounding. In addition, the droplets and aerosols that are produced when the person breathes and speaks normally, the droplets and aerosols produced at this time are not as fast as when coughing or sneezing, and the mouth and nose of the person can be in the negative pressure adsorption cavity Outside the position closer to the suction port of the negative pressure adsorption cavity, the negative pressure airflow can also quickly suck the droplets and aerosols generated by the human nose into the negative pressure adsorption cavity. Therefore, regardless of the strong airflow generated by coughing and sneezing or the weak airflow generated by normal speech and breathing, the present invention can enable the aerosol and droplets produced by personnel to be quickly sucked out of the enclosed room, avoiding Aerosols and droplets stay in the closed room, so that when a person leaves the closed room after using the closed room, the aerosol and droplets produced by the person will not remain in the closed room, so that the next person can continue to use the closed room safely .
而且通过在封闭间内再设置负压吸附腔，因负压吸附腔离人的口鼻近，且口鼻还可直接处在负压吸附腔内，使得不需要强气流即能吸走人员产生的飞沫及气溶胶，解决了弱气流不能在人员咳嗽、打喷嚏情况下快速吸走其产生的飞沫及气溶胶的问题，因此能让封闭间内的人员处在自然的微风状态下并快速地吸走人员产生的气溶胶及飞沫，能给人舒适的感觉。Moreover, by setting up a negative pressure adsorption cavity in the closed room, the negative pressure adsorption cavity is close to the mouth and nose of a person, and the mouth and nose can also be directly in the negative pressure adsorption cavity, so that the person can be sucked away without strong air flow. The droplets and aerosols solve the problem that the weak airflow cannot quickly absorb the droplets and aerosols generated by the people in the case of coughing or sneezing, so that the people in the enclosed room can be in a natural breeze state and It can quickly absorb the aerosol and droplets generated by the personnel, which can give people a comfortable feeling.
本实施例中，所述第一除菌装置和第二除菌装置为采用过滤的方式消除有害细菌及病毒的过滤装置。当然在不同实施例中，所述第一除菌装置和第二 除菌装置还可以为通过高温杀灭有害细菌及病毒的高温除菌装置，或者所述第一除菌装置和第二除菌装置还可以为通过等离子杀灭有害细菌及病毒的等离子除菌装置。In this embodiment, the first sterilization device and the second sterilization device are filtering devices that eliminate harmful bacteria and viruses by filtering. Of course, in different embodiments, the first sterilization device and the second sterilization device may also be high temperature sterilization devices that kill harmful bacteria and viruses through high temperature, or the first sterilization device and the second sterilization device The device can also be a plasma sterilization device that kills harmful bacteria and viruses through plasma.
且本实施例中人员密集区对有害细菌及病毒的防护装置，使得在单人独处的封闭间内，人员不必戴口罩，且封闭间内气流通畅，呼吸舒适性好，解决了长时间佩戴口罩容易造成不舒适的技术问题。In addition, the protective device for harmful bacteria and viruses in the crowded area in this embodiment eliminates the need for people to wear masks in a closed room where one person is alone, and the airflow in the closed room is smooth, and the breathing comfort is good, which solves the problem of wearing masks for a long time. It is easy to cause uncomfortable technical problems.
