Description

Technical Field

[0001] The invention relates to the technical field of air purification devices, in particular to an air sterilization device for preventing the spread of infectious diseases in hospitals. Background Art

[0002] The air sterilization device used by hospitals to prevent the spread of infectious diseases is mainly a medical air disinfector. A medical air disinfector is a device specifically used to disinfect and purify the air in a medical environment. When in use, the indoor air enters the air disinfector through the air inlet. The air disinfector filters and disinfects the incoming air with ultraviolet light to remove or kill microorganisms such as bacteria, viruses, and fungal spores in the air. The treated air is then discharged back into the room through the air outlet to provide a clean and safe medical environment.

[0003] When the medical air disinfector is working, air humidity is the key factor affecting the penetration of ultraviolet rays. Water molecules in the air can absorb ultraviolet rays. Therefore, in an environment with high air humidity, the penetration of ultraviolet rays will be weakened, thereby reducing the disinfection effect. Different areas in the hospital have different requirements for air humidity. The appropriate humidity range is helpful for the recovery of patients and the work of medical staff. For example, the humidity in the pediatric ward is recommended to be maintained at 55%-65%, and the humidity in other wards can be between 40%-60%. Medical staff need to adjust the disinfection power of the medical air disinfector according to the air humidity, which increases the complexity of operation. In an environment with high air humidity, the water film formed on the surface of dust particles in a high humidity environment changes its charge state and adhesion, and at the same time enhances the physical attraction between the dust particles and the surface of the lamp tube, making it easier for dust in the air to adhere to the surface of the lamp tube. In order to maintain the stability and reliability of the equipment, medical staff need to maintain and service the disinfector more frequently, which increases the maintenance cost. To this end, we propose an air sterilization device for preventing the spread of infectious diseases in hospitals. Summary of the invention

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1

[0032] See also Figures 1 to 9 The present invention provides a technical solution: an air sterilization device for preventing the spread of infectious diseases in hospitals, comprising a disinfection machine body 1, an air inlet 2 and an exhaust port 3; further comprising a purification chamber 4, the purification chamber 4 is located inside the disinfection machine body 1, and the air inlet 2 and the exhaust port 3 are respectively connected to the purification chamber 4; an ultraviolet lamp 5, the ultraviolet lamp 5 is fixed on the inner wall of the purification chamber 4; an airflow detection mechanism 6, the airflow detection mechanism 6 is installed on the inner wall of the purification chamber 4, the airflow detection mechanism 6 is located outside the air inlet 2, and the airflow detection mechanism 6 detects the airflow humidity at the air inlet 2; a guide mechanism 7, the guide mechanism 7 is installed on the inner wall of the purification chamber 4, the guide mechanism 7 is connected to the exhaust port 3, when the airflow detection mechanism 6 detects that the airflow humidity discharged from the air inlet 2 increases, the guide mechanism 7 processes part of the discharged air and guides the processed air to the surface of the ultraviolet lamp 5.

[0033] When in use, after the disinfection machine body 1 works, the external airflow is sucked into the purification chamber 4 through the air inlet 2, and the gas in the purification chamber 4 is purified and sterilized by the ultraviolet lamp 5, and the purified gas is re-discharged into the outside through the exhaust port 3. When the gas is sent into the purification chamber 4 through the exhaust port 3, the humidity of the airflow sucked into the air inlet 2 is monitored by the airflow detection mechanism 6. If the airflow humidity increases, the power of the ultraviolet lamp 5 is controlled to increase, and part of the airflow after disinfection by the ultraviolet lamp 5 is redirected into the purification chamber 4 through the guide mechanism 7, and the re-entering airflow is heated by the resistance wire 75. As the humidity detected by the airflow detection mechanism 6 increases, the current passed through the resistance wire 75 increases, thereby improving the drying efficiency. The guide mechanism 7 sprays dry hot air onto the surface of the ultraviolet lamp 5 to cooperate with the cleaning of dust and water mist attached to the surface of the ultraviolet lamp 5, so as to avoid the attachment of dust and water mist to affect the sterilization and purification effect of the ultraviolet lamp 5, reduce the maintenance frequency of the ultraviolet lamp 5 by medical staff, and reduce maintenance costs.

[0034] The airflow detection mechanism 6 includes a mounting base 60 fixedly connected to the inner wall of the purification chamber 4, a limiting groove 61 is provided on the inner wall of the mounting base 60, a pressure sensor 62 is fixedly connected to the inner wall of the limiting groove 61, a connecting base 63 is fixedly connected to the bottom of the pressure sensor 62, the connecting base 63 is located on the inner wall of the limiting groove 61, and a collecting part 64 is provided on the side of the connecting base 63 close to the air inlet 2.

[0035] When the airflow enters the purification chamber 4 through the air inlet 2, since the collecting piece 64 is blocked on the outside of the air inlet 2, when the airflow passes through the collecting piece 64, the collecting piece 64 will absorb the moisture in the passing airflow. After the collecting piece 64 absorbs the moisture, the overall weight of the collecting piece 64 and the connecting seat 63 increases, so that the pressure on the pressure sensor 62 increases. If the humidity of the airflow is stable, as the air inlet 2 continuously blows the airflow to the collecting piece 64, the pressure change amplitude on the pressure sensor 62 changes linearly. If the humidity of the airflow increases, the moisture absorbed by the collecting piece 64 will also increase. At this time, the pressure change on the pressure sensor 62 increases significantly. The disinfection machine body 1 controls the power of the ultraviolet lamp 5 to increase according to the pressure change of the pressure sensor 62, so as to automatically adjust the power of the ultraviolet lamp 5 when the humidity increases, thereby improving the purification and sterilization effect of the ultraviolet lamp 5 in a high humidity environment. Similarly, if the pressure change on the pressure sensor 62 is greatly reduced, the disinfection machine body 1 reduces the power of the ultraviolet lamp 5 to reduce energy consumption.

[0036] The collecting member 64 includes two rotating rods 65 rotatably connected to the inner wall of the connecting seat 63, and the two rotating rods 65 are respectively located at the upper and lower ends of the connecting seat 63. A plurality of guide rods 66 are fixedly connected to the inner wall of the connecting seat 63. A hygroscopic belt 67 is slidably connected to the outer side of the guide rod 66. The hygroscopic belt 67 is composed of cloth 69 and silica gel 610. The silica gel 610 is close to the air inlet 2. The two ends of the hygroscopic belt 67 are respectively wrapped around the surface of the rotating rod 65 and fixed to the rotating rod 65. A winding member 68 is provided on the outer side of one of the rotating rods 65 for driving the rotating rod 65 to wind up the hygroscopic belt 67.

[0037] Silica gel 610 is an excellent adsorbent with a porous structure and a surface area of ​​500-600m² / g, which enables it to absorb a large amount of moisture in the gas. Therefore, when the air inlet 2 discharges the airflow into the purification chamber 4, the hygroscopic belt 67 blocking the outside of the air inlet 2 will absorb the moisture in the airflow through the silica gel 610. After the silica gel 610 absorbs the moisture, the weight of the hygroscopic belt 67 increases, so that the pressure detected by the pressure sensor changes continuously. When the moisture content in the airflow remains unchanged, the pressure change on the pressure sensor 62 will always change linearly. If the moisture content in the air increases or decreases, the amplitude of the pressure change on the pressure sensor 62 will change. Each time the disinfection machine body 1 is started, the winding member 68 will drive one of the rotating rods 65 to rotate, so that the rotating rod 65 will wind up the used hygroscopic belt 67 on its surface and pull the unused hygroscopic belt 67 to the outside of the air inlet 2.

[0038] The winding member 68 includes a rotating motor 611 installed on the inner wall of the connecting seat 63, the output end of the rotating motor 611 is connected to the rotating rod 65, and a mobile power supply 612 is installed on the inner wall of the connecting seat 63. The mobile power supply 612 is connected to the rotating motor 611. When the disinfection machine body 1 is started, the mobile power supply 612 supplies power to the rotating motor 611, and the rotating motor 611 drives the rotating rod 65 to rotate through the output shaft to cooperate with the used hygroscopic belt 67 to be wound on the surface of the rotating rod 65, and the unused hygroscopic belt 67 is moved to the outside of the air inlet 2.

[0039] The guide mechanism 7 includes a guide tube 70 connected to the exhaust port 3. An air treatment component 71 is provided at one end of the guide tube 70 away from the exhaust port 3. The air treatment component 71 is connected to the pressure sensor 62. An air storage box 72 is fixedly connected to the outside of the ultraviolet lamp 5. A cleaning component 73 for cleaning the ultraviolet lamp 5 is provided on the inner wall of the air storage box 72.

[0040] When in use, the disinfection machine body 1 works to discharge the gas in the purification chamber 4 through the exhaust port 3, and guides part of the discharged gas to the air treatment component 71 through the guide tube 70. The air treatment component 71 processes the incoming airflow, and when the pressure change amplitude of the pressure sensor 62 increases, the power of the air treatment component 71 increases to cooperate with the rapid drying treatment of the incoming gas. The treated gas enters the gas storage box 72, and the cleaning component 73 uses the gas in the gas storage box 72 to clean the surface of the ultraviolet lamp 5 to avoid dust and water mist from affecting the sterilization and purification effect of the ultraviolet lamp 5, thereby reducing the maintenance frequency of the ultraviolet lamp 5 by medical staff and reducing maintenance costs.

[0041] The air treatment component 71 includes an air treatment box 74 connected to the guide tube 70. A resistance wire 75 is installed on the inner wall of the air treatment box 74. A controller 76 is provided at one end of the resistance wire 75. The controller 76 is installed on the inner wall of the air treatment box 74. The controller 76 is connected to the pressure sensor 62. An exhaust pipe 77 is connected to the bottom of the air treatment box 74, and the exhaust pipe 77 is connected to the air storage box 72.

[0042] After the guide tube 70 guides the airflow into the air treatment box 74, the resistance wire 75 is energized to generate heat to cooperate with the drying of the air in the air treatment box 74. As the pressure sensor 62 transmits the received pressure signal to the controller 76, the controller 76 processes the information transmitted by the pressure sensor 62. If the pressure change amplitude increases, the controller 76 controls the current intensity entering the resistance wire 75 to increase, so that the resistance wire 75 generates more heat, accelerates the evaporation of moisture in the air, and improves the drying efficiency. The dried gas enters the air storage box 72 through the exhaust pipe 77.

[0043] The cleaning component 73 includes a distribution box 78 located on the inner wall of the air storage box 72, a sealing ring 79 is fixedly connected to the outer side of the distribution box 78, a sealing groove 710 slidably connected to the sealing ring 79 is provided on the inner wall of the air storage box 72, the sealing ring 79 is sealedly connected to the inner wall of the sealing groove 710, a nozzle 711 is connected to the bottom of the distribution box 78, and a transmission component 712 is provided on the inner wall of the distribution box 78 to drive the distribution box 78 to rotate.

[0044] After the exhaust pipe 77 delivers the dried gas into the gas storage box 72, the gas entering the gas storage box 72 drives the transmission member 712 to work, and the transmission member 712 drives the distribution box 78 to rotate, and the distribution box 78 drives the sealing ring 79 to rotate on the inner wall of the sealing groove 710. After the gas in the gas storage box 72 enters the distribution box 78, it is sprayed out through the nozzle 711, and the nozzle 711 blows the dry hot air flow to the surface of the ultraviolet lamp 5. The rotation of the distribution box 78 drives the nozzle 711 to rotate, so that the nozzle 711 can spray the air flow to the whole body of the ultraviolet lamp 5 to cooperate with the cleaning of the surface of the ultraviolet lamp 5, avoid the adhesion of dust and water mist to affect the sterilization and purification effect of the ultraviolet lamp 5, reduce the maintenance frequency of the ultraviolet lamp 5 by medical staff, and reduce the maintenance cost.

[0045] The transmission member 712 includes a transmission ring 713 fixedly connected to the inner wall of the distribution box 78, and a plurality of blades 714 are fixedly connected to the outer side of the transmission ring 713. One side of the blade 714 is in a concave arc shape. After the airflow enters the air storage box 72, it impacts the concave arc position of the blade 714. After the blade 714 is blown, it drives the transmission ring 713 to rotate. The rotation of the transmission ring 713 drives the distribution box 78 to rotate, so that the nozzle 711 rotates around the lamp tube surface of the ultraviolet lamp 5.

[0046] Embodiment 2

[0047] like Fig.10 In the second embodiment, other structures remain unchanged. The difference from the first embodiment is that the flow area of ​​the exhaust pipe 77 is gradually reduced to increase the flow rate of the airflow entering the air storage box 72, so as to drive the distribution box 78 to rotate.
