Description

Ultraviolet air disinfection assembly and air disinfection device
Technical Field
The invention relates to an ultraviolet air disinfection component and an air disinfection device comprising the same.
Background
With the increasing severity of air pollution, especially in the seasons with high incidence of infectious diseases such as influenza and pneumonia, air becomes a carrier of various pollutants, bacteria and viruses, which causes great hidden troubles to human health. Therefore, air purification becomes a very important link of daily life.
The current common air purification means is to adopt an air purifier to purify the indoor air. The air purifier usually consists of a motor, a fan and a filter device, wherein the motor and the fan circulate indoor air, and the air removes or adsorbs various pollutants after passing through the filter device in the air purifier. For antibacterial purposes, various antibacterial devices, such as an electrostatic electret screen design, an anion and plasma design, an ultraviolet sterilization device, etc., are generally provided in the air purifier.
However, the antibacterial devices such as the ultraviolet sterilization device and the negative ion device usually generate ozone in the working process, and generate secondary pollution to air. In order to remove ozone, the most direct method at present is to heat to accelerate the decomposition of ozone, but if sufficient air quantity does not pass through, accidents such as fire hazard may occur under the condition that the heat is continuously heated but the heat cannot be timely dissipated, so that the air disinfection device needs to be further improved.
In addition, in addition to indoor space, people can spend a lot of time in various vehicles, especially in various vehicles, and the space in a car is usually narrow, which is not suitable for using an air disinfection device to disinfect and sterilize air in the car, therefore, further improvement on the existing air disinfection device is needed, and a disinfection component which can be conveniently applied to various occasions is designed.
Disclosure of Invention
According to the ultraviolet air disinfection assembly, ultraviolet disinfection, heating and heat dissipation functions are integrated in the ultraviolet radiation resistant shielding cylinder, bacteria and viruses in the air are sterilized through the ultraviolet disinfection system, then the air is heated to at least over 56 ℃, preferably over 60 ℃ through the heating device, on one hand, secondary inactivation treatment is carried out on the viruses through high temperature, on the other hand, ozone generated in the ultraviolet disinfection process can be rapidly decomposed at over 60 ℃, so that secondary pollution of the ozone to the air is eliminated, the air disinfection and purification effects are well guaranteed, the heat dissipation device can rapidly dissipate heat of the heating device, and accidents are prevented. In order to ensure that enough air quantity passes through the ultraviolet air disinfection component of the invention to dissipate heat in time, the ultraviolet air disinfection component of the invention is also provided with an air speed switch control system to control the working state of the heating device. The ultraviolet air disinfection component has compact structure through function and structure integration, and can be conveniently installed on various parts such as an air disinfector, an air conditioning unit ventilation pipeline and the like.
The ultraviolet air disinfection component of the invention is characterized in that: the ultraviolet air disinfection component 10 comprises an ultraviolet disinfection system 1, a heating system 2, a circuit and control system 3 and an ultraviolet shielding system 4;
A. the circuit and control system 3 comprises a circuit system 31 and a control system 32; the control system 32 comprises a wind speed switch control system 32-1; the wind speed switch control system 32-1 is installed at the front end of the heating system 2, when air passes through the wind speed switch control system 32-1, the wind speed switch control system 32-1 is switched on, and the heating system 2 works;
B. the ultraviolet disinfection system 1 is arranged in the ultraviolet shielding system 4 and is arranged at the front end of the heating system 2;
C. the ultraviolet disinfection system 1 and the heating system 2 are connected with a power supply through the circuit and control system 3.
The ultraviolet air disinfection component of the invention comprises the ultraviolet disinfection system 1 and the heating system 2. After air enters the ultraviolet air disinfection component 10, the air is subjected to ultraviolet sterilization and disinfection by the ultraviolet disinfection system 1, and then is heated by the heating system 2, so that on one hand, the decomposition of ozone generated in the sterilization process of the ultraviolet disinfection system 1 is accelerated, and on the other hand, bacteria and viruses possibly remaining in the air are further killed. The ultraviolet air disinfection component 10 integrates the ultraviolet disinfection system 1 and the heating system into the ultraviolet shielding system 4, has compact structure, and can be conveniently installed in an air disinfection device or arranged in each ventilation pipeline to sterilize and disinfect air.
The wind speed switch control system 32-1 comprises a wind collecting port 32-11, a switch plate 32-12, a photoelectric switch 32-13 and a switch mounting base 32-14; when air passes through the air collecting opening 32-11, the switch plate 32-12 is driven to move, light rays emitted by the photoelectric switch 32-13 are shielded, the photoelectric switch 32-13 is switched on, and the heating system 2 is switched on to start working and generate heat.
When air flows through, the switch plate 32-12 rotates under the action of wind force, the control end 32-12-2 of the switch plate 32-12 shields light emitted by the photoelectric switch 32-13, the photoelectric switch 32-13 is switched on, and the heating system 2 is switched on to start working and heating. When no air flows through or the air quantity is too small, the switch plate 32-12 cannot be driven to rotate by wind power, the switch plate 32-12 falls back under the action of gravity, light rays emitted by the photoelectric switch 32-13 are not shielded, the photoelectric switch 32-13 is switched off, the heating system 2 is powered off, and the work is stopped.
To ensure that the air can drive the switch board 32-12 through the air collecting opening 32-11, the air collecting opening 32-11 of the air speed switch control system 32-1 is generally installed between the air inlet 41 of the ultraviolet air sterilizing assembly 10 and the heating system 2, so as to ensure that the circulated air can be effectively received and the heating system 2 can be effectively protected.
The switch plate 32-12 comprises a wind power adjusting mechanism 32-12-1. The wind power adjusting mechanism 32-12-1 can adjust the size of the critical value of the movement of the switch board 32-12, namely the starting critical value of the wind power adjusting mechanism 32-12-1, so as to achieve the optimal balance among the temperature of the air outlet, the concentration of ozone and the disinfection and sterilization effects. In practical application, the most suitable motion threshold of the switch board 32-12 can be adjusted according to the required wind speed, so as to ensure that the air volume flowing through the ultraviolet air disinfection component 10 meets the use requirement. The wind power adjusting mechanism 32-12-1 can be a mechanical adjusting mechanism or an electronic adjusting mechanism, and when the wind power adjusting mechanism 32-12-1 is an electronic adjusting mechanism, the motion threshold of the switch board 32-12 can be directly set in the interface of a control system.
The heating system 2 can rapidly decompose ozone generated in the sterilization and disinfection process of the ultraviolet disinfection system 1, and reduce the ozone content in the air discharged into the room after sterilization and disinfection.
The heating system 2 is a heating rod 21, and/or a heating plate 22, and/or a heating coil 23. The heating system 2 may be one of the above heating manners, or may be a combination of multiple heating manners, and in practical applications, a person skilled in the art may also design different heating manners according to needs, and the applicant does not exemplify this, but does not depart from the scope of the present application.
The heating coil 23 is formed by winding a heating wire 23-1 along the air flowing direction and is longitudinally distributed. The winding mode longitudinally distributed along the air flowing direction can widen the air heating distance to the maximum extent, and has better effects of killing virus and decomposing ozone.
The temperature of the heating system 2 is not less than 56 ℃. For most viruses, the capsid protein of the virus is denatured at 55-60 ℃, usually within several minutes, so that the virus loses its infection ability, and therefore, when the temperature of the heating system 2 is controlled to be above 56 ℃, or above 60 ℃, the inactivation effect of the virus can be better ensured. Meanwhile, the ozone generated in the sterilization and disinfection process of the ultraviolet disinfection system 1 can be rapidly decomposed at the temperature of more than 50 ℃, so that the secondary pollution of the ozone generated in the sterilization and disinfection process to air is avoided.
The heating system 2 can heat the air subjected to ultraviolet sterilization by the ultraviolet sterilization system 1 and maintain the set temperature. The heating system 2 is provided with a temperature setting device, so that the heating temperature of the heating system 2 is kept constant, and the optimal heating temperature can be set for different infection sources according to needs, thereby better ensuring the virus inactivation effect.
The ultraviolet air disinfection module 10 also contains a heat dissipation system 5. The heat dissipation system 5 can reduce the temperature of the heated air, and prevent the air heated by the heating system 2 from being too high in temperature to damage peripheral components or prevent accidental injury caused by too high air outlet temperature. Meanwhile, the heat dissipation system 5 can also better ensure the safe operation of the heating system 2, and prevent the heating system 2 from causing accidents such as smoke, fire and the like under the continuous high-temperature state.
The heat dissipation system 5 is a heat dissipation plate 51, and/or a heat dissipation coil 52, and/or a heat dissipation post 53. The heat dissipation system 5 may be one or a combination of several heat dissipation manners, and those skilled in the art may also design different heat dissipation structures according to needs, which are not illustrated herein by the applicant, without departing from the scope of the present application.
The ultraviolet shielding system 4 is made of ultraviolet radiation resistant materials, ultraviolet leakage can be prevented, ultraviolet intensity in the ultraviolet shielding system 4 can be enhanced through reflection of ultraviolet rays, and the sterilization effect is enhanced. Because ultraviolet sterilization and disinfection are achieved by destroying the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in the cells of the microorganism body by ultraviolet with proper wavelength to cause death of growing cells and/or death of regenerative cells. Therefore, if the ultraviolet disinfection system is not protected while sterilizing, a certain amount of accidental injury may be caused to the human body, and therefore, the ultraviolet disinfection system 1 needs to be installed in the ultraviolet shielding system 4 to form a closed isolation so as to avoid the accidental injury to the human body. The UV screening system 4 is typically made of specular stainless steel, or specular glass, or a specular polymer material that is UV resistant and reflects UV light.
The ultraviolet shielding system 4 is a stainless steel tubular structure. The stainless steel tubular structure can minimize the structure volume, is convenient to install in various pipelines, and is particularly suitable for sterilization and disinfection of an air-conditioning pipeline system.

The ultraviolet light monitoring system 6 can monitor the ultraviolet light emitted by the ultraviolet lamp 11 of the ultraviolet disinfection system 1 to judge whether the ultraviolet lamp 11 works normally.

Generally, the air inlet 30-1 is disposed at a lower portion of the housing 30, and the air outlet 30-2 is disposed at an upper portion of the housing 30.

Detailed Description
Example 1: the ultraviolet air disinfection component of the present invention
Referring to fig. 1-7, the ultraviolet air sanitizer assembly 10 includes an ultraviolet sanitizer system 1, a heating system 2, a circuitry and control system 3, and an ultraviolet shield system 4.
The circuit and control system 3 described with reference to fig. 1-2 through 1-7 includes circuitry 31 and a control system 32; the control system 32 comprises a wind speed switch control system 32-1; the wind speed switch control system 32-1 is installed at the front end of the heating system 2, when air passes through the wind speed switch control system 32-1, the wind speed switch control system 32-1 is switched on, and the heating system 2 works.
The ultraviolet disinfection system 1 is arranged in the ultraviolet shielding system 4 and is arranged at the front end of the heating system 2.
The ultraviolet disinfection system 1 and the heating system 2 are connected with a power supply through the circuit and control system 3.
Referring to fig. 1-2 to fig. 1-7, in the present embodiment, the wind speed switch control system 32-1 includes a wind collecting opening 32-11, a switch board 32-12, a photoelectric switch 32-13 and a switch mounting seat 32-14; when air passes through the air collecting opening 32-11, the switch plate 32-12 is driven to move, light rays emitted by the photoelectric switch 32-13 are shielded, the photoelectric switch 32-13 is switched on, and the heating system 2 is switched on to work and generate heat.
Referring to fig. 1-6 and fig. 1-7, when air flows through, the switch board 32-12 rotates under the action of wind force, the control end 32-12-2 of the switch board 32-12 blocks the light emitted by the photoelectric switch 32-13, the photoelectric switch 32-13 is turned on, and the heating system 2 is turned on to start working and heating. When no air flows through or the air quantity is too small, the switch plate 32-12 cannot be driven to rotate by wind power, the switch plate 32-12 falls back under the action of gravity, light rays emitted by the photoelectric switch 32-13 are not shielded, the photoelectric switch 32-13 is switched off, the heating system 2 is powered off, and the work is stopped.
To ensure that the air can drive the switch board 32-12 through the air collecting opening 32-11, the air collecting opening 32-11 of the air speed switch control system 32-1 is generally installed between the air inlet 41 of the ultraviolet air sterilizing assembly 10 and the heating system 2, so as to ensure that the circulated air can be effectively received and the heating system 2 can be effectively protected.
The heating system 2 can rapidly decompose ozone generated in the sterilization and disinfection process of the ultraviolet disinfection system 1, and reduce the ozone content in the air discharged into the room after sterilization and disinfection.
Referring to fig. 6, in the present embodiment, the heating system 2 is a heating coil 23.
The heating coil 23 is formed by winding a heating wire 23-1 along the air flowing direction and is longitudinally distributed. The winding mode longitudinally distributed along the air flowing direction can widen the air heating distance to the maximum extent, and has better effects of killing virus and decomposing ozone.
The heating system 2 may also be a heating bar, and/or a heating plate. In practical applications, a person skilled in the art may also design different heating manners according to needs, and the applicant does not exemplify these heating manners, but does not depart from the scope of the present application.
The temperature of the heating system 2 is not less than 56 ℃. For most viruses, the capsid protein of the virus is denatured at 55-60 ℃, usually within several minutes, so that the virus loses its infection ability, and therefore, when the temperature of the heating system 2 is controlled to be above 56 ℃, or above 60 ℃, the inactivation effect of the virus can be better ensured. Meanwhile, the ozone generated in the sterilization and disinfection process of the ultraviolet disinfection system 1 can be rapidly decomposed at the temperature of more than 50 ℃, so that the secondary pollution of the ozone generated in the sterilization and disinfection process to air is avoided.
Referring to fig. 7, the heating system 2 can heat and maintain a set temperature of the air uv-sterilized by the uv sterilizing system 1. The heating system 2 is provided with a temperature setting device, so that the heating temperature of the heating system 2 is kept constant, and the optimal heating temperature can be set for different infection sources according to needs, thereby better ensuring the virus inactivation effect.
The ultraviolet shielding system 4 is made of ultraviolet radiation resistant materials, ultraviolet leakage can be prevented, ultraviolet intensity in the ultraviolet shielding system 4 can be enhanced through reflection of ultraviolet rays, and the sterilization effect is enhanced. Because ultraviolet sterilization and disinfection are achieved by destroying the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in the cells of the microorganism body by ultraviolet with proper wavelength to cause death of growing cells and/or death of regenerative cells. Therefore, if the ultraviolet disinfection system is not protected while sterilizing, a certain amount of accidental injury may be caused to the human body, and therefore, the ultraviolet disinfection system 1 needs to be installed in the ultraviolet shielding system 4 to form a closed isolation so as to avoid the accidental injury to the human body. The UV screening system 4 is typically made of specular stainless steel, or specular glass, or a specular polymer material that is UV resistant and reflects UV light. In order to prevent the damage of peripheral components caused by the leakage of ultraviolet rays, a light shielding plate 43 is arranged between the ultraviolet disinfection system 1 and the heating system 2.
In this embodiment, the ultraviolet shielding system 4 is a stainless steel tubular structure. The stainless steel tubular structure can minimize the structure volume, is convenient to install in various pipelines, and is particularly suitable for sterilization and disinfection of an air-conditioning pipeline system.
The ultraviolet air sanitizer assembly 10 also includes an ultraviolet light monitoring system 6. The ultraviolet light monitoring system 6 can monitor the ultraviolet light emitted by the ultraviolet lamp 11 of the ultraviolet disinfection system 1 to judge whether the ultraviolet lamp 11 works normally.
The UV air sterilizer assembly of this embodiment comprises the UV sterilization system 1 and the heating system 2. After air enters the ultraviolet air disinfection component 10, the air is subjected to ultraviolet sterilization and disinfection by the ultraviolet disinfection system 1, and then is heated by the heating system 2, so that on one hand, the decomposition of ozone generated in the sterilization process of the ultraviolet disinfection system 1 is accelerated, and on the other hand, bacteria and viruses possibly remaining in the air are further killed. The ultraviolet air disinfection component 10 integrates the ultraviolet disinfection system 1 and the heating system into the ultraviolet shielding system 4, has compact structure, and can be conveniently installed in an air disinfection device or arranged in each ventilation pipeline to sterilize and disinfect air.
Example 2: ultraviolet air disinfection assembly of the present invention including a heat dissipation system
Referring to fig. 2 to 3, the present embodiment is different from embodiment 1 in that the uv disinfection air assembly 10 further includes a heat dissipation system 5.
The heat dissipation system 5 can reduce the temperature of the heated air, and prevent the air heated by the heating system 2 from being too high in temperature to damage peripheral components or prevent accidental injury caused by too high air outlet temperature. Meanwhile, the heat dissipation system 5 can also better ensure the safe operation of the heating system 2, and prevent the heating system 2 from causing accidents such as smoke, fire and the like under the continuous high-temperature state.
In this embodiment, the heat dissipation system 5 is the flower-shaped heat dissipation column 53. The flower-shaped structure can well increase the heat dissipation area and has better heat dissipation effect.
Referring to fig. 4-1, the heat dissipation system 5 may also be other structures such as a heat dissipation plate 51, and/or a heat dissipation coil 52, and may also be a combination of one or more of the above heat dissipation manners, and a person skilled in the art may also design different heat dissipation structures according to needs, which is not illustrated herein by the applicant, without departing from the scope of the present application.
Referring to fig. 2-4 and 2-5, in this embodiment, the switch plate 32-12 includes a wind adjustment mechanism 32-12-1. The wind power adjusting mechanism 32-12-1 can adjust the size of the critical value of the movement of the switch board 32-12, namely the starting critical value of the wind power adjusting mechanism 32-12-1, so as to achieve the optimal balance among the temperature of the air outlet, the concentration of ozone and the disinfection and sterilization effects. In practical application, the most suitable motion threshold of the switch board 32-12 can be adjusted according to the required wind speed, so as to ensure that the air volume flowing through the ultraviolet air disinfection component 10 meets the use requirement. The wind power adjusting mechanism 32-12-1 can be a mechanical adjusting mechanism or an electronic adjusting mechanism, and when the wind power adjusting mechanism 32-12-1 is an electronic adjusting mechanism, the motion threshold of the switch board 32-12 can be directly set in the interface of a control system.
Compared with embodiment 1, the present embodiment is safer in use due to the design of the heat dissipation system 5.
