Description

Technical Field

[0001] This utility model relates to an indoor air sterilizer and belongs to the field of disinfection technology. Background Technology

[0002] Currently, air sterilizers can be used for indoor air disinfection. For example, Chinese patent document CN112843278B discloses a handheld medical cold-sealed air plasma jet spray gun, including a device shell and a discharge electrode, Tesla coil, touch screen, cooling fan, internal circuit, control switch, and power lithium battery installed inside the device shell. The power lithium battery is connected to the touch screen, control switch, and Tesla coil through the internal circuit. Stable, continuous, and high-density cold plasma is generated by the discharge of the Tesla coil, which has high sterilization efficiency, universality, and flexibility, and can meet the sterilization needs of the medical field. At the same time, it has a smaller device size, is easy to carry, and is easy to operate. Chinese patent document CN112972744A discloses an ozone air disinfection and purifier, including a main shell with a top cover. An exhaust fan is installed inside the main shell, and a control module is installed on the exhaust fan. An ozone generating module is installed inside the main shell and located at the output part of the exhaust fan. Power supply modules are symmetrically arranged on both sides of the exhaust fan inside the main shell. A storage groove is provided at the bottom of the outer side of the main shell, and a bottom cover is provided at the bottom of the outer side of the main shell. This air purifier has a simple structure, small size, is easy to install, and is highly practical. Using this ozone air disinfection purifier, viruses and bacteria in the air and on objects in contact with the air can be effectively killed, and toxic gases such as formaldehyde and benzene can be removed, effectively improving air quality and reducing the impact of poor-quality air on human health. The ozone generating module used in this invention produces ozone with extremely high purity and very little peroxide, achieving safe use and enabling coexistence between humans and the machine. Chinese patent document CN115875791A discloses a device for disinfection and purification of the novel coronavirus, mainly comprising a cylindrical shell with an air inlet and an air outlet. From the air inlet to the air outlet, a primary filter module, a virus disinfection module, a high-efficiency interception module, an integrated gaseous pollutant filter module, and a fan module are arranged sequentially. The primary filter module uses fiber fabric as its filter material; the virus disinfection module has a built-in U-shaped ultraviolet lamp, with both its air inlet and outlet surfaces covered by filter screens; the high-efficiency interception module uses a HEPA filter element of H13 or higher, with non-woven fabric as the filter material; the integrated gaseous pollution filter module uses one or a mixture of high-quality coconut shell activated carbon, wood activated carbon, and fruit shell activated carbon. This equipment integrates honeycomb activated carbon module materials, various air purifiers, and ultraviolet sterilization technologies, featuring good removal of viruses carried by aerosols in the air, high disinfection and purification efficiency, safe use, and no secondary pollution. However, these disinfection methods rely on a single virus-killing approach and cannot leverage the synergistic effect of multiple disinfection methods, thus hindering the improvement of disinfection effectiveness. Utility Model Content

[0003] To overcome the aforementioned deficiencies of the prior art, this utility model provides an indoor air sterilizer that integrates multiple virus disinfection methods into one unit, achieving thorough virus disinfection, high efficiency, low operating costs, and no pollution.

[0004] The technical solution of this utility model to achieve the above-mentioned objective is: an indoor air sterilizer, including a housing, an air inlet and an air outlet on the housing, an air delivery pipe between the air inlet and the air outlet, a Tesla coil inside the housing, the discharge end of the Tesla coil located inside the air delivery pipe, a fan provided at the air inlet or the air outlet, and a cover plate provided at both the air inlet and the air outlet, the cover plate being a grid plate or a perforated plate.

[0005] Preferably, the housing contains a liquid container with an air inlet and an air outlet. The air inlet is connected to the air inlet, and the air outlet is connected to the air inlet of the air delivery pipe.

[0006] Preferably, the liquid containers are a plurality of containers connected in series. The air inlet of the liquid container located at the front along the air delivery direction is connected to the air inlet, and the air outlet of the liquid container located at the rear is connected to the air delivery pipe inlet.

[0007] Furthermore, there are three liquid containers, which are, from front to back, a hot water container, an alkaline solution container, and an ethanol container. The hot water container is used to hold water, the alkaline solution container is used to hold alkaline solution, and the ethanol container is used to hold 75% ethanol.

[0008] Preferably, the hot water container is equipped with an electric heater.

[0009] Preferably, the hot water container is equipped with a temperature sensor, and the signal output of the temperature sensor is connected to the control terminal of the electric heater.

[0010] Preferably, the temperature of the hot water in the hot water container is not lower than 65°C.

[0011] Furthermore, the temperature of the hot water in the hot water container is not lower than 90°C.

[0012] Preferably, each of the liquid containers is equipped with a one-way valve on its front end pipe (for air delivery).

[0013] Preferably, the housing is provided with a liquid replenishment port for each of the liquid containers.

[0014] Furthermore, each of the aforementioned fluid inlets is equipped with a fluid inlet cap.

[0015] Preferably, the air delivery pipe is divided into an electric shock sterilization section and a deep ultraviolet sterilization section from front to back along the air delivery direction. The discharge end of the Tesla coil is located in the electric shock sterilization section. The deep ultraviolet sterilization section is a glass tube with a deep ultraviolet light source on one side or around it.

[0016] Preferably, the deep ultraviolet disinfection section is spiral-shaped.

[0017] The air delivery pipe may or may not have a weak X-ray disinfection section behind the deep ultraviolet disinfection section. When a weak X-ray disinfection section is provided, a weak X-ray source is provided on one side or around the weak X-ray disinfection section.

[0018] The beneficial effects of this utility model are:

[0019] (1) Tesla coils can provide tens of thousands of volts of DC discharge. By utilizing the arc effect generated by high voltage discharge, the lipid layer on the surface of the virus can be destroyed instantly, and the virus can be quickly killed. The virus disinfecting effect is good and efficient. At the same time, the high voltage discharge of Tesla coils can also ionize the air, generate ozone and a variety of active oxygen and hydroxyl radicals, destroy the survival biofield of the virus, and cause it to lose its survival conditions, further improving the virus disinfecting effect. Tesla coil discharge has the characteristics of high voltage and low current, and is highly safe to use and will not cause danger.

[0020] (2) Because of the liquid container, the air can be humidified before the airborne virus is electrocuted, increasing the water molecule content in the air. In particular, the humidity in the air can be basically saturated, which improves the conductivity (discharge conduction capacity) of the air. This is beneficial to increase the arc length and coverage of the electric arc during the high-voltage discharge of the Tesla coil, thereby improving the disinfection effect and efficiency of the virus.

[0021] (3) Using hot water to humidify the air can achieve the effect of humidifying the air. After the heat dissipation of the subsequent process, the relative humidity will be further increased, which is conducive to reaching or maintaining a saturated state. At the same time, the high temperature can be used to initially disinfect the viruses in the air. Combined with the disinfection methods of alkaline solution and ethanol, most of the viruses in the air can be killed before the virus electric shock disinfection, reducing the pressure of virus electric shock disinfection. After the virus electric shock disinfection, the air is further irradiated with deep ultraviolet light and / or weak X-ray to kill the residual viruses in the air, thus achieving comprehensive disinfection of the viruses in the air and finally obtaining fresh, clean and non-toxic air.

[0022] (4) This utility model integrates high-temperature disinfection, alkaline / ethanol disinfection, electric shock disinfection, deep ultraviolet disinfection and weak X-ray disinfection of viruses. By carrying out multi-level disinfection of viruses in the air, the disinfection effect of viruses in the air is guaranteed and the disinfection efficiency is improved. The disinfection of viruses only uses water, alkaline / ethanol and electricity as raw materials and resources, which reduces the cost of use. Attached Figure Description

[0023] Figure 1 This is a structural schematic diagram of one embodiment of the present invention. Detailed Implementation

[0024] See Figure 1 This utility model discloses an indoor air sterilizer, including a housing 1, an air inlet 2 and an air outlet 3, and an air delivery pipe between the air inlet and the air outlet. A Tesla coil is housed inside the housing, and the discharge end (discharge electrode) 4 of the Tesla coil is located within the air delivery pipe. When air flows through the air delivery pipe, the Tesla coil discharges at high voltage, utilizing the arc effect generated by the high-voltage discharge to electrocute bacteria, viruses, and other pathogens in the air, instantly destroying the lipid layer on the surface of the virus and achieving virus elimination. The high-voltage discharge of the Tesla coil can also ionize the air, generating ozone and various reactive oxygen species and hydroxyl radicals, disrupting the virus's biofield and depriving it of its survival conditions, further improving the virus elimination effect. Furthermore, the Tesla coil discharge has the characteristics of high voltage and low current, ensuring high safety and posing no danger. Based on the discharge characteristics, the discharge electrodes can be rationally arranged to ensure that all (as much as possible under actual conditions) of the air flows through the discharge area and that the "residence" time (time spent in the discharge area) is maximized. The air inlet or the air outlet is equipped with a fan 5 to provide power for air circulation. Both the air inlet and the air outlet are equipped with a cover plate, which is a grille plate or a perforated plate, to intercept dust, floating objects, or flying insects in the air. The air inlet can be located on the side wall of the housing, and the air outlet can be located on the top wall of the housing.

[0025] Preferably, a liquid container is provided inside the housing. The liquid container has an air inlet and an air outlet. The air inlet is connected to the air inlet (sealed connection via a pipe), and the air outlet is connected to the air inlet of the air delivery pipe (sealed connection or sealed connection via a pipe). Preferably, there are several liquid containers arranged in series. That is, among adjacent liquid containers, the air outlet of the container in front is sealed to the air inlet of the container behind it via a pipe. The air inlet of the liquid container furthest along the air delivery direction is sealed to the air inlet, and the air outlet of the container furthest back is sealed to the air inlet of the air delivery pipe. Typically, there are three liquid containers: a hot water container (6), an alkaline solution container (7), and an ethanol container (8), from front to back. The hot water container holds hot water, which humidifies the air, increasing the water molecule content and bringing the humidity to near saturation. This improves the air's conductivity (discharge conductivity), which is beneficial for increasing the arc length and coverage during the high-voltage discharge of the Tesla coil, thus enhancing the virus disinfection effect and efficiency. It also utilizes high temperature to disinfect viruses in the air. The alkaline solution container holds alkaline solution, and the ethanol container holds 75% ethanol. The alkaline solution and ethanol destroy the lipid layer on the surface of the virus, achieving alkaline and ethanol disinfection. When the indoor air sterilizer is in use, air enters the housing through the air inlet under the action of the fan, flowing sequentially through the hot water container, alkaline solution container, and ethanol container. After high-temperature, alkaline, and ethanol disinfection, the air enters the air delivery pipe. This reduces the pressure of the electric shock disinfection process, ensuring that the air after electric shock disinfection is virtually free of surviving viruses. The number of liquid containers can also be set to two, namely a hot water container and an alkaline / ethanol container, using only one of the alkaline or ethanol solutions to disinfect the air.

[0026] The hot water container is preferably equipped with an electric heater 9 for heating the water in the hot water container. The hot water container is preferably equipped with a temperature sensor, and the signal output of the temperature sensor is connected to the control terminal of the electric heater to facilitate the control of the heating temperature of the water in the hot water container.

[0027] The temperature of the hot water in the hot water container is usually not lower than 65°C, preferably not lower than 90°C, in order to ensure the high-temperature disinfection effect on the virus.

[0028] The alkaline solution contained in the alkaline solution container is preferably a sodium carbonate solution, a sodium bicarbonate solution, or a sodium hypochlorite solution.

[0029] Each of the liquid containers is preferably equipped with a one-way valve on its front end pipe (for air delivery) to prevent backflow of liquid within the container.

[0030] All liquid containers are preferably made of glass, with the air inlet located at the bottom and the air outlet at the top. In use, each liquid container is filled with an appropriate amount of liquid, typically between 2 / 3 and 3 / 4 of the container's height.

[0031] The housing is preferably provided with a replenishment port for each of the liquid containers for replenishing the liquid containers. Each replenishment port is preferably provided with a replenishment port cap.

[0032] The air delivery pipe is preferably divided into an electric shock disinfection section 10 and a deep ultraviolet disinfection section 11 from front to back along the air delivery direction. The discharge end of the Tesla coil is located in the electric shock disinfection section. The deep ultraviolet disinfection section is a glass tube with a deep ultraviolet (wavelength 200-350nm) light source 12 on one side or around it. The deep ultraviolet light source can be a deep ultraviolet LED lamp, which is used to irradiate the air after the virus electric shock disinfection (deep ultraviolet disinfection) with deep ultraviolet light, destroying the DNA molecules, cell structure and function of the virus (microorganism), so that it loses its vitality and kills the virus remaining in the air.

[0033] The deep ultraviolet disinfection section is preferably spiral-shaped to extend the air transport path and the time of deep ultraviolet irradiation, thereby improving the virus disinfection effect.

[0034] A weak X-ray disinfection section 13 may or may not be provided behind the deep ultraviolet disinfection section of the air delivery pipe. When a weak X-ray disinfection section is provided, it is a glass tube with a weak X-ray source 14 on one side or around it. The weak X-ray source can be a weak X-ray machine, used to irradiate the air after deep ultraviolet disinfection (weak X-ray irradiation disinfection) with weak X-rays, destroying the protein activity of the virus and causing it to die, further ensuring the disinfection effect of the virus in the air. Alternatively, a weak X-ray disinfection section can be provided behind the deep ultraviolet disinfection section of the air delivery pipe. A mounting slot or port for a weak X-ray source is reserved near the weak X-ray disinfection section in the housing for use when the air quality is severely poor (when the virus content in the air is high), to install a weak X-ray source for weak X-ray irradiation disinfection of the air after deep ultraviolet disinfection.

[0035] The layout of the various reaction components in this sterilizer (e.g., containers for each reaction, air delivery pipes for the reaction, etc.) can be flexibly configured according to actual needs, and can be vertical or horizontal. In a horizontal configuration, the components are arranged sequentially along a horizontal axis, or in a three-dimensional distribution, such as arranged in two (or more) layers, with axial (longitudinal) or transverse (perpendicular to the longitudinal direction) arrangements within the same layer. In a vertical configuration, a multi-layered three-dimensional distribution with multiple components arranged within the same layer is also possible. The piping and supporting facilities for the input and output of liquids within the containers should also be configured according to actual needs.

[0036] The described indoor air sterilizer integrates multiple virus disinfection methods, offering excellent and efficient virus disinfection in the air. It also features a simple structure, small footprint, and uses only water, alkaline solution / ethanol, and electricity for virus disinfection, resulting in low operating costs. A single 160W device can meet the needs of at least 200m². 2 Disinfection and purification of viruses in the air within the space.

[0037] Unless otherwise specified or further limited to one preferred or optional technical means being another, the preferred and optional technical means disclosed in this utility model can be arbitrarily combined to form several different technical solutions.
