Description

Technical Field

[0001] The invention relates to the technical field of air sterilization, and in particular to an intelligent and environmentally friendly air sterilization spray device. Background Art

[0002] The air sterilization spray device converts disinfectant or sterilizing agent into tiny droplets through spray technology, and sprays it evenly into the air through the built-in spray system of the equipment. These tiny droplets can fully contact with bacteria, viruses and other microorganisms in the air, thereby achieving the purpose of sterilization; the method of disinfection by spraying belongs to static disinfection and sterilization technology. When performing work disinfection, static sterilization technology has a direct or indirect impact on people active in the room. It is often used when there are no people active in the room, and the usage scenarios are greatly restricted. Therefore, a disinfection method combining dynamic disinfection technology and static disinfection technology has emerged in the prior art. When there are people active in the room, the indoor air is disinfected and sterilized through a dynamic disinfection device; when there are no people active in the room, a static disinfection device is used to disinfect the indoor air; static disinfection technology and dynamic disinfection technology are combined with each other to achieve human-machine coexistence, and can disinfect and sterilize indoor air around the clock.

[0003] However, in the prior art, the static disinfection technology and the dynamic disinfection technology are combined in the disinfection device, and the dynamic disinfection is usually carried out by a single method. When the dynamic sterilization device with good disinfection and sterilization effect is used, although the disinfection and sterilization effect is good, the energy consumption is high, the maintenance is troublesome, and the cost is high. When the dynamic sterilization and disinfection device with general sterilization effect is used, although the energy consumption is low, it is difficult to sterilize and disinfect the indoor air quickly and efficiently when the indoor air quality is poor. Therefore, it is urgent to develop an intelligent and environmentally friendly air sterilization spray device that can combine dynamic and static disinfection technologies and has a variety of dynamic disinfection devices that cooperate with each other, so as to ensure the indoor air quality while reducing the required energy consumption.

[0030] A main controller 10 electrically connected to the first reversing valve 9, the second reversing valve 45, the dynamic sterilization component 4 and the static sterilization component 5 is also provided on the outside of the box 1; a collection module electrically connected to the main controller 10 is also provided on the box 1; the collection module includes a humidity sensor 11 fixedly installed on one side of the outside of the box 1 for collecting indoor air humidity; an air quality sensor 12 fixedly installed on one side of the outside of the box 1 for collecting indoor air quality; a human body sensor 13 fixedly installed on the bottom of the box 1 for sensing whether there is a human body in the room; and a liquid level sensor 14 fixedly installed in the liquid storage tank 51 for sensing the remaining amount of disinfectant in the liquid storage tank 51.

[0031] Working principle:

[0032] The air sterilizing spray device of the present invention is provided with a dynamic sterilizing component 4 and a static sterilizing component 5 in a box body 1; the dynamic sterilizing component 4 includes an ultraviolet disinfection device 41 and a plasma disinfection device 42. When the dynamic sterilizing component 4 is working, it has no harm or influence on the human body. When the air is disinfected, the personnel do not need to leave the disinfection place, and there is no side effect; the static sterilizing component 5 includes a liquid storage tank 51 and an atomizing device 52, etc., and when working, spray is generated, which has direct or indirect influence, but the spray generated by it can fully disinfect the air in every corner of the room, and the disinfection effect is good without dead angles; the dynamic sterilizing component 4 and the static sterilizing component 5 are electrically connected to the main controller 10, and by presetting the working time range in the main controller 10, the dynamic sterilizing component 4 works when there are people active in the room during the day, and the static sterilizing component 5 works when there are no people active in the room at night; the static and dynamic are combined with each other to achieve the coexistence of man and machine, and can disinfect and sterilize the indoor air around the clock.

[0033] When the present invention is working, the indoor air is introduced into the first ventilation duct 6 of the box body 1 through the fan arranged at the air inlet 2, and the air entering the first ventilation duct 6 first passes through the filter component 16, and the filter component 16 filters the dust and small particles floating in the air; the filtered air is transported to the first reversing valve 9 arranged at the connection between the first ventilation duct 6 and the third ventilation duct 8; when there is no human activity in the room at night, the main controller 10 controls the first reversing valve 9 to open and the third ventilation duct 8 to close, and the air enters the static sterilization component 5 through the third ventilation duct 8, and the main controller 10 controls the atomization device 52 in the static sterilization component 5 to work, and the liquid storage tank 51 is controlled by The infusion tube 53 transports the disinfectant to the atomizing device 52, the atomizing device 52 atomizes the disinfectant, and the atomized disinfectant is transported to the third ventilation duct 8. The air in the third ventilation duct 8 drives the atomized disinfectant to be sprayed from the spray pipe 55 into the room. The sprayed atomized disinfectant can be suspended in the air, and can more effectively contact and kill microorganisms in the air; at the same time, a human body sensor 13 is provided at the lower end of the outer side of the box body 1. When the static sterilization component 5 is in working time, the human body sensor 13 senses whether there is anyone active in the room. When there is someone active in the room, the main controller 10 interrupts the operation of the static sterilization component 5 to prevent affecting the normal activities of the people in the room.

[0034] When there are people active in the room during the day, the main controller 10 controls the first reversing valve 9 to open the first ventilation duct 6 and close the third ventilation duct 8. The air entering the box body 1 enters the dynamic sterilization component 4 through the first ventilation duct 6. The dynamic sterilization component 4 includes an ultraviolet disinfection device 41, a plasma disinfection device 42, a fourth ventilation duct 43, a fifth ventilation duct 44 and a second reversing valve 45. An air quality sensor 12 electrically connected to the main controller 10 is arranged outside the box body 1; the air quality sensor 12 collects indoor air quality data at intervals and transmits it to the main controller 10. When the air quality sensor 12 collects indoor air quality data, the air quality sensor 12 collects indoor air quality data at intervals and transmits it to the main controller 10. When the collected air quality data exceeds the preset range value in the main controller 10, the main controller 10 controls the second reversing valve 45 in the dynamic sterilization component 4 to open the fifth ventilation duct 44 and close the fourth ventilation duct 43; the air entering the dynamic sterilization component 4 enters the plasma disinfection device 42 through the fifth ventilation duct 44 for disinfection and sterilization; the plasma disinfection device 42 has high disinfection efficiency, can kill microorganisms in the air in a short time, is harmless to the human body and the environment, can remove odors and harmful gases in the air at the same time, and has higher energy consumption than the ultraviolet disinfection device 41; the air disinfected by the plasma disinfection device 42 passes through the The second ventilation duct 7 is discharged to the exhaust port 3, and finally discharged from the exhaust port 3 to the room; when the air quality data collected by the air quality sensor 12 is within the range value preset in the main controller 10, the main controller 10 controls the second reversing valve 45 in the dynamic sterilization component 4 to open the fourth ventilation duct 43 and close the fifth ventilation duct 44, and the air entering the dynamic sterilization component 4 enters the ultraviolet disinfection device 41 through the fourth ventilation duct 43 for disinfection and sterilization; the ultraviolet disinfection device 41 has good sterilization ability and can effectively kill bacteria and viruses in the air; and it is simple to operate and has lower energy consumption than the plasma disinfection device 42. The maintenance cost is low, and the air can be disinfected and sterilized for a long time; the air disinfected by the ultraviolet disinfection device 41 is discharged to the exhaust port 3 through the second ventilation duct 7, and finally discharged into the room from the exhaust port 3; by combining the ultraviolet disinfection device 41 and the plasma disinfection device 42, when the air quality is poor and rapid disinfection and sterilization is required, the indoor air is quickly disinfected and sterilized by the energy-intensive ion disinfection device; when the air quality is within a reasonable range, the air is continuously disinfected and sterilized by the ultraviolet disinfection device 41 with low energy consumption; while ensuring the indoor air quality, the energy consumption required is reasonably reduced.

[0035] At the same time, a dehumidification component 46 is fixedly arranged in the fourth ventilation duct 43 on the side of the ultraviolet disinfection device 41 close to the second reversing valve 45; a humidity sensor 11 is arranged on the outer side of the box body 1. When the ultraviolet disinfection device 41 is working, the humidity data of the indoor air is collected by the humidity sensor 11. When the indoor air humidity exceeds the preset range value in the main controller 10, the main controller 10 controls the dehumidification component 46 to work, and the dehumidification component 46 dehumidifies the air entering the fourth ventilation duct 43 to prevent the air from being too humid. The water molecules in the air absorb ultraviolet rays, resulting in reduced penetration of ultraviolet rays, thereby affecting the disinfection effect.

[0036] At the same time, a liquid level sensor 14 electrically connected to the main controller 10 is fixedly installed in the liquid storage tank 51 in the static sterilization component 5, and is used to collect the remaining data of the disinfectant in the liquid storage tank 51. When the remaining amount of disinfectant in the liquid storage tank 51 collected by the liquid level sensor 14 is lower than the preset value in the main controller 10, the main controller 10 generates an electrical signal to the alarm light 15 set outside the box 1, and the alarm light 15 lights up to remind the staff to add disinfectant in time.

[0037] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0038] Although the present disclosure has been described in detail with reference to the exemplary embodiments, the present disclosure is not limited thereto, and it will be apparent to those skilled in the art that various modifications and changes may be made thereto without departing from the scope of the present disclosure.
