Description

Technical Field

[0001] This utility model relates to the field of disinfection equipment technology, and in particular to a disinfection device. Background Technology

[0002] Currently, disinfection devices mainly include methods such as ultraviolet irradiation, filter filtration, and electrostatic adsorption. Ultraviolet irradiation technology uses specific wavelengths of ultraviolet light to directly act on the DNA structure of microorganisms, disrupting their replication ability and thus achieving sterilization. However, ultraviolet light poses certain risks to human health and must be used when no one is present, limiting its application scenarios. Furthermore, ultraviolet disinfection requires a certain irradiation time to achieve effective sterilization, and its efficiency is relatively low in rapidly flowing air or large spaces.

[0003] Filter technology utilizes the principle of physical interception, using filters of different materials and pore sizes to capture pollutants such as particulate matter and microorganisms in the air. Although this method is highly effective in removing larger particles, filters are prone to saturation and need to be replaced regularly, increasing maintenance costs and inconvenience. More importantly, a saturated filter may become a new source of pollution; if it is not replaced in time, the captured pollutants may be released back into the air, causing secondary pollution.

[0004] Electrostatic adsorption technology uses a high-voltage electric field to charge airborne particles, which are then collected by a dust collection plate. This technology is effective at removing certain particle sizes (especially larger particles), but it is less efficient at handling fine particles (such as PM2.5 and viral aerosols). Furthermore, over long-term operation, dust accumulation on the dust collection plate can affect its adsorption efficiency, requiring regular cleaning and maintenance.

[0005] Existing air disinfection and purification devices cannot simultaneously meet the requirements of high efficiency, safety, low maintenance costs, and wide applicability. Utility Model Content

[0028] The following is combined Figures 1-2 This invention describes the disinfection device.

[0029] The disinfection device provided in this embodiment of the utility model includes: a housing 1, a xenon lamp module 2, and a pulse drive module. The housing 1 contains a disinfection chamber 11; the xenon lamp module 2 is disposed within the disinfection chamber 11; the xenon lamp module 2 includes a transparent lamp tube and electrodes, with the electrodes disposed within the transparent lamp tube; the transparent lamp tube is at least sealed and filled with xenon gas; the transparent lamp tube includes an alumina lamp tube and a quartz tube coated with an alumina coating; the pulse drive module is connected to the xenon lamp module 2 and is used to apply a high-voltage pulse to the disinfection chamber 11 to generate a high-energy ionization effect and a photon effect.

[0030] The xenon lamp module 2 provided in this embodiment is a pulsed xenon lamp module 2. The transparent lamp tube is an alumina lamp tube and a quartz tube coated with an alumina coating, which can withstand the thermal shock generated during high-voltage xenon gas discharge. Compared with traditional quartz glass lamp tubes, alumina material has a higher melting point, stronger mechanical strength, and broad-spectrum optical transmittance. It is commonly used in harsh industrial environments, optical testing, and high-efficiency disinfection applications. Alumina (Al2O3) is a ceramic material with excellent thermal, mechanical, and optical properties. Its performance in high-temperature and corrosive environments is far superior to quartz or other glass materials. Transparent alumina is an alumina material with high optical transparency formed under a special preparation process. Transparent alumina has a high melting point (2072°C), higher than most other glass materials (such as quartz, whose melting point is about 1650°C). Transparent alumina has broad-spectrum transmittance, and can transmit the ultraviolet to mid-infrared (about 200 nm to 5000 nm) spectrum. Transparent alumina possesses high mechanical strength, with a compressive strength exceeding 500 MPa and a hardness reaching 15 GPa, which is 2-3 times that of ordinary quartz. It exhibits excellent corrosion resistance and chemical stability, resisting most acids, alkalis, and high-temperature corrosive gases (such as hydrofluoric acid and chlorine). Transparent alumina also demonstrates high absorption capacity for deep ultraviolet light at 185 nm and below, thus preventing ozone formation when used in ultraviolet light sources.

[0031] The electrodes are located inside the transparent lamp tube. In one embodiment, electrodes are provided at both ends of the transparent lamp tube, and the electrodes are connected to the two ends of the transparent lamp tube by laser welding or vacuum brazing. The electrodes can be made of tungsten (W), molybdenum (Mo), or tungsten alloy to form a high electric field strength and ensure the stability of pulse discharge. The electrodes can be designed in a needle shape or a cone shape to increase the local electric field strength and form a stable pulse discharge region.

[0032] The transparent lamp tube is also sealed and filled with xenon gas. In one embodiment, the transparent lamp tube is filled with xenon gas and a certain proportion of nitrogen gas, wherein the nitrogen gas concentration can reach 99.99%, which has excellent discharge characteristics and high luminous efficiency.

[0033] It should be noted that the xenon gas is sealed inside the transparent lamp tube. In the actual manufacturing process, after filling with xenon gas, a matching low-expansion coefficient ceramic or metal foil is used to seal the transparent alumina tube using laser welding or a high-temperature oxyhydrogen flame to ensure the airtightness and thermal stability of the transparent lamp tube.

[0034] The xenon lamp module 2 provided in this embodiment of the present invention uses xenon gas as a discharge light source and an alumina lamp tube made of alumina material or a quartz tube coated with alumina as the lamp tube, which has strong durability, mechanical stability and corrosion resistance; by applying a high-speed, short-time pulse voltage to it through a pulse drive module, a high-energy ionization effect and a photon effect are generated, which can quickly and efficiently disinfect and purify the air to meet practical needs.

[0035] like Figure 1 and Figure 2 As shown, a disinfection chamber 11 is constructed inside the housing 1, and a xenon lamp module 2 is disposed inside the disinfection chamber 11 for disinfecting the air inside the disinfection chamber 11. In this embodiment of the present invention, the xenon lamp module 2 can be one or more, such as... Figure 2 As shown, there are three xenon lamp modules 2, which are distributed at intervals along the circumference of the disinfection chamber 11. In one embodiment, the three xenon lamp modules 2 are evenly distributed within the disinfection chamber 11, resulting in a more comprehensive disinfection effect.

[0036] The pulse drive module is connected to the xenon lamp module 2. After startup, it generates a high-energy ionization effect and photon effect by applying a high-speed, short-duration pulse voltage to the gas flow path, causing microorganisms in the air to be broken by the strong electric field impact, thereby eliminating bacteria, viruses and organic pollutants suspended in the air in the disinfection chamber 11.

[0037] The disinfection device provided in this embodiment of the utility model, by placing the xenon lamp module 2 inside the disinfection chamber 11 and connecting the pulse drive module to the xenon lamp module 2, after the pulse module is activated, acts on the air in the gas flow path through the pulse electric field to generate a highly efficient ionization, decomposition and purification effect, thereby achieving comprehensive disinfection and purification of suspended microorganisms, organic pollutants and odor molecules in the air; the device has a simple structure, can process a large volume of air in a short time, is highly safe, low in cost, and can adapt to different scenarios.

[0038] The pulse drive module includes an energy storage unit, a pulse transformer, and a controller. The energy storage unit is used for power connection, forming a stable DC voltage after rectification and filtering. The energy storage unit stores energy for use when the pulse is emitted, ensuring sufficient current is provided during discharge. The energy storage unit includes a capacitor bank and a supercapacitor. The pulse transformer is used to increase the voltage to meet the requirements of high-voltage applications. In actual operation, the pulse transformer is controlled to open, triggering a high-voltage switch to form a short-duration high-voltage pulse. The switching is very fast, typically on the nanosecond to microsecond scale. The energy storage unit is connected to the input of the pulse transformer, and the output of the pulse transformer is connected to the xenon lamp module 2. The pulse transformer converts the energy in the energy storage unit into high voltage before inputting it to the xenon lamp module 2. Furthermore, the pulse transformer, energy storage unit, and xenon lamp module 2 are all connected to the controller, which can acquire relevant parameters (such as voltage and current) in real time and make adjustments based on the real-time data.

[0039] In one embodiment, the housing 1 further comprises an airflow control chamber 14. The housing 1 has an inlet 12 and an outlet 13. The inlet 12 communicates with the disinfection chamber 11, allowing air to enter and be disinfected. The disinfection chamber 11 communicates with the airflow control chamber 14, and the outlet 13 communicates with the airflow control chamber 14. Disinfected air in the disinfection chamber 11 is discharged through the airflow control chamber 14 and the outlet 13. In one embodiment, the inlet 12 is located on the side wall of the housing 1, corresponding to the disinfection chamber 11. Multiple inlets 12 may be used. Similarly, multiple outlets 13 may also be located on the side wall of the housing 1, corresponding to the airflow control chamber 14.

[0040] In one embodiment, the disinfection device further includes a fan 3, which is disposed in the airflow control chamber 14. The airflow in the airflow control chamber 14 is adjusted by adjusting the speed of the fan 3, thereby achieving the adjustment of the airflow in the disinfection chamber 11.

[0041] To better regulate airflow changes, the disinfection device provided in this embodiment of the invention further includes multiple flow guides. These flow guides are adjustablely disposed within the airflow control chamber 14, located between the outlet 13 and the fan 3. By adjusting the position of the flow guides, the airflow rate and direction at the outlet 13 are adjusted, preventing local gas stagnation or excessively rapid flow. The airflow control chamber 14 is provided with a sliding groove, which can be disposed on the bottom or top surface of the airflow control chamber 14. The multiple flow guides are slidably connected to the sliding groove. In one embodiment, each flow guide is connected to a driving component, which drives the movement of the flow guide.

[0042] In one embodiment, the outlet 13 is located on the side wall of the housing 1, corresponding to the airflow control cavity 14. Multiple guide elements are adjustablely located on the outer periphery of the fan 3. By increasing or decreasing the distance between two adjacent guide elements, the flow rate and direction of the airflow at the outlet 13 can be adjusted to avoid local gas stagnation or excessively fast flow.

[0043] The disinfection device in this embodiment of the present invention also includes a control module 4. The xenon lamp module 2, the pulse drive module and the fan 3 are all electrically connected to the control module 4. The control module 4 can adjust the operating parameters of the xenon lamp module 2, the pulse drive module and the fan 3 according to the actual situation.

[0044] In one embodiment, an airflow sensor is provided at outlet 13 to acquire airflow parameters at outlet 13, including flow rate and direction. The airflow sensor is electrically connected to control module 4, which receives real-time data from the airflow sensor and controls the operation of fan 3; and / or, the drive unit is electrically connected to control module 4, which, based on the real-time data from the airflow sensor, controls the operation of the drive unit and adjusts the position of the guide component, thereby adjusting the airflow flow rate and direction at outlet 13.

[0045] In one embodiment, the disinfection device further includes an environmental monitoring module, which is used to acquire current environmental parameters and is electrically connected to the control module 4.

[0046] The environmental monitoring module includes a laser particle sensor for real-time detection of particulate matter concentration in the air, as well as harmful gases (VOCs, formaldehyde, etc.). The module may also include a semiconductor gas sensor for detecting formaldehyde, volatile organic compounds, and other harmful gases. This semiconductor gas sensor can also be an electrochemical sensor. Furthermore, the module may include an ozone sensor (such as a gas-selective electrochemical probe) to detect the ozone concentration generated by pulsed discharge, ensuring it does not exceed a safe threshold (typically set at 0.1 ppm).

[0047] It should be noted that the sampling frequency is typically set to 1-5 times / second to ensure real-time monitoring of air quality. Data filtering and processing: Kalman filtering or adaptive filtering algorithms are used to remove noise and interference signals during the sampling process. Multi-sensor data fusion technology is used to identify and classify different types of pollutants (such as smoke, dust, and chemical pollutants).

[0048] The environmental monitoring module monitors both the external and internal environmental conditions of the disinfection chamber 11 to ensure optimal disinfection performance under various conditions. The module may also include a temperature sensor located within the disinfection chamber 11 to monitor the temperature of electrodes, transparent lamps, or other high-temperature components. Additionally, it may include a humidity sensor located within the chamber to detect ambient humidity and prevent pulse discharges in excessively high humidity conditions, thus avoiding insulation failure or arcing. Finally, the module may include two airflow sensors, one at the inlet 12 and the other at the outlet 13, to monitor airflow and velocity in real time, ensuring uniform and compliant airflow.

[0049] In one embodiment, the disinfection device further includes an alarm module, which is electrically connected to the control module 4. The control module 4 receives real-time data transmitted by the environmental monitoring module. When the control module 4 detects abnormal data, such as excessively high temperature, excessively high humidity, or abnormal airflow, the control module 4 controls the alarm module to issue alarm information, such as an alarm sound or voice message.

[0050] The disinfection device in this embodiment of the invention also includes a communication module, which is electrically connected to the control module 4. The communication module is used to communicate with external devices, including mobile phones, tablets, and computers. Users can view the current operating parameters of the disinfection device through these external devices and adjust its operation accordingly. The communication module includes Wi-Fi and Bluetooth modules, connecting to home or office networks and supporting remote monitoring, parameter adjustment, and fault diagnosis. Internet of Things (IoT) platform access: Data is uploaded to a cloud platform via MQTT or HTTP protocols, allowing users to view the device's operating status in real time and perform remote control via a mobile app.

[0051] It should be noted that the disinfection device has a standard disinfection mode, a strong disinfection mode, and an energy-saving mode. The standard disinfection mode is suitable for routine air disinfection, maintaining a medium airflow and pulse power. When air pollution is severe, the strong disinfection mode is activated to increase airflow and pulse intensity, shortening the disinfection time. When air quality is good, the energy-saving mode is used to reduce pulse frequency and airflow, extending the equipment's lifespan. Users can select the disinfection mode directly through control module 4 or through external devices.

[0052] In one embodiment, the disinfection device further includes a display screen, which is located on the housing 1 and can be positioned on the top of the housing 1 for easy user operation. The display screen is electrically connected to the control module 4, allowing users to interact with the device. The display screen can show the operating parameters of each module, including the current operating mode, air quality parameters, operating time, etc., and can also display historical data. The display screen can be a touch screen or an OLED display.

[0053] It should be noted that the control module 4 in this embodiment manages and coordinates the operation of various modules, and commonly used chips include STM32, ESP32, or processors based on the ARM Cortex-M series. The internal algorithm integrates multiple control algorithms and optimization strategies to improve disinfection effectiveness, reduce energy consumption, and extend equipment lifespan.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
