Description

TECHNICAL FIELD

[0001] The utility model relates to a sterilization device technical field especially, it relates to a kind of based on deep ultraviolet LED of remote wireless monitoring's sterilization device. BACKGROUND

[0002] In recent years, with the continuous expansion of investment in research and development of nitride deep ultraviolet LED, the external quantum efficiency (WPE) of nitride deep ultraviolet LED is also gradually improved, and the life is also rising, which has exceeded the life of traditional mercury lamp, which makes the deep ultraviolet LED, called green, environmentally friendly and healthy light source, replace mercury lamp further, and currently high-power object surface sterilization module, air sterilization module, flowing water sterilization module have been successively put into research and use, which can realize the rapid "killing" of bacteria and viruses on the carrier irradiated by light source such as object surface, air and water. Moreover, deep ultraviolet LED belongs to semiconductor material, which can realize instant-on and repeated switching operation without affecting its life, and can reduce the energy consumption of module. At the same time, deep ultraviolet LED has small size, which can be placed arbitrarily according to structural requirements, and customized design, so that the ultraviolet light source irradiation is more sufficient and has no dead angle, the utilization efficiency of ultraviolet light source is improved, and the sterilization efficiency is improved.

[0003] However, for such ultraviolet light source for sterilization and disinfection, its irradiation intensity must be detected in real time to avoid affecting its sterilization effect. The traditional monitoring method is to measure periodically by artificial on-site, which cannot monitor ultraviolet irradiation intensity in real time and cannot judge whether the module works normally. At the same time, ultraviolet light source is generally installed in a closed space, which makes artificial measurement extremely inconvenient or impossible. Even in the space that is easy to measure, there is a security risk of being injured under the condition that a large dose of ultraviolet light source is turned on. At the same time, in some use scenarios, sterilization and disinfection are performed at regular intervals or periodically, and do not need to work for a long time. Because traditional ultraviolet light source (mercury lamp) needs to be preheated and repeated switching affects its life, it is usually not recommended to be turned off, which makes the intensity of ultraviolet light source decay faster and cannot meet the sterilization requirement, and the replacement and maintenance cost increases. In addition, the existing ultraviolet light source (UVC-LED) needs to be set up a special post to control, which increases the operation cost. UTILITY MODEL CONTENT

[0041] As shown in Figures 1 to 4 The deep ultraviolet LED germicidal module comprises a shell 1, a quartz glass 2 is internally mounted on one side of the shell 1, a copper substrate 7 is internally mounted in the shell 1, a plurality of deep ultraviolet LED lamp beads 8 are arranged in a circular array form on the copper substrate 7, the light emitting side of the deep ultraviolet LED lamp beads 8 faces the quartz glass 2, a heat dissipation fin 3 is connected to the side of the shell 1 away from the quartz glass 2, a fan shell 14 is connected to the side of the heat dissipation fin 3 away from the shell 1, and an axial flow fan is internally mounted in the fan shell 14.

[0042] The sensing module at least comprises a plurality of ultraviolet intensity sensors 5, and the plurality of ultraviolet intensity sensors 5 are mounted on the copper substrate 7.

[0043] The remote wireless monitoring assembly comprises a microcontroller module 21, the microcontroller module 21 comprising a power supply unit, a data acquisition unit, a wireless remote data transceiver unit, a control unit, an alarm unit and a relay control unit, the power output end of the power supply unit being electrically connected with the power input ends of the data acquisition unit, the wireless remote data transceiver unit, the control unit, the alarm unit and the relay control unit, the signal input end of the data acquisition unit being electrically connected with the signal output end of the sensing module, the signal output end of the data acquisition unit being electrically connected with the signal input end of the control unit, the signal output end of the control unit being electrically connected with the signal input ends of the relay control unit and the alarm unit, the signal output end of the relay control unit being electrically connected with the signal input end of the adjustable current constant current power supply, the adjustable current constant current power supply being electrically connected with the deep ultraviolet LED lamp bead 8, the wireless remote data transceiver unit being bidirectionally connected with the control unit, the wireless remote data transceiver unit being bidirectionally connected with the monitoring terminal remotely, and the control unit being further electrically connected with the adjustable current constant current power supply.

[0044] Specifically, the deep ultraviolet LED lamp bead 8 emits ultraviolet rays with a wavelength of 265-280 nm and a light power of more than 30 mW, and the light emitting angle of the deep ultraviolet LED lamp bead 8 is 60° or 120°. The deep ultraviolet LED lamp bead 8 can break the DNA or RNA gene chain of bacteria or viruses, so that the bacteria or viruses cannot be replicated or lose activity, thereby achieving the purpose of sterilization.

[0045] In order to make the heat dissipation effect of the deep ultraviolet LED sterilization module better, the copper with the best heat conductivity coefficient is selected as the substrate in the embodiment of the utility model, the connecting line is laid in the copper substrate 7, and the deep ultraviolet LED lamp beads 8 are arranged in an array on the copper substrate 7.

[0046] The axial flow fan is used for secondary fan heat dissipation for the deep ultraviolet LED lamp bead 8, so as to further ensure the heat dissipation effect. The fan shell 14 is used for forming the containing space of the axial flow fan. The axial flow fan is fixed on the heat dissipation fin 3 through the fan mounting hole 12 and the screw. The axial flow fan comprises the fan blade 10 and the fan shaft 13, and the fan blade 10 is connected to the fan shaft 13.

[0048] The heat dissipation fin 3 is integrally formed with the shell 1 and is distributed at the tail end of the shell 1.

[0049] The adjustable current constant current power supply is used to provide constant input current for the deep ultraviolet LED sterilization module, and can also adjust the current of the deep ultraviolet LED sterilization module through the control unit in the microcontroller module 21 as needed. The adjustable current constant current power supply is installed near the deep ultraviolet LED sterilization module and is electrically connected with the deep ultraviolet LED lamp beads 8 through a cable.

[0050] The ultraviolet intensity sensor 5 is the main sensor of the sterilization device. Whether the deep ultraviolet LED sterilization module works normally and whether the intensity of the deep ultraviolet LED lamp beads 8 decreases after a long time of lighting will directly affect the sterilization effect of the sterilization device. The ultraviolet intensity sensor 5 can monitor the ultraviolet intensity of the deep ultraviolet LED sterilization module in real time. When it is found that the ultraviolet intensity is lower than a certain threshold, the control unit sends an alarm signal to the alarm unit to prompt that the deep ultraviolet LED sterilization module is working abnormally. The ultraviolet intensity sensor 5 is internally composed of an ultraviolet intensity receiving probe, a signal amplifier, a reference power supply, an A / D conversion unit, etc. The ultraviolet intensity receiving probe is used to receive the ultraviolet intensity signal output by the deep ultraviolet LED lamp beads 8; the signal amplifier is used to amplify the ultraviolet intensity signal and convert it into a voltage signal, and the amplification multiple is determined by an external sampling resistor; the reference power supply is a stable reference voltage output by a voltage stabilizing chip for supplying the signal amplifier to work; and the A / D conversion unit is used to convert the collected analog voltage signal into a digital voltage signal and transmit it to the signal input end of the control unit.

[0051] The power supply unit in the microcontroller module 21 is used to supply power to the entire microcontroller module 21. The data acquisition unit is used to acquire the data collected by the sensing module and transmit the data to the control unit. The control unit determines whether the data collected by the sensing module needs to be alarmed, and if so, sends an alarm signal to the alarm unit for sound and light alarm. The control unit also remotely sends the data collected by the sensing module to the monitoring terminal through the wireless remote data transceiver unit. The control unit also controls whether the adjustable current constant current power supply drives the deep ultraviolet LED lamp beads 8 to emit light through the relay control unit. When the control unit determines that the deep ultraviolet LED lamp beads 8 need to be controlled to emit light, the control unit controls the relay in the relay control unit to be conductive, so that the adjustable current constant current power supply drives the deep ultraviolet LED lamp beads 8 to emit light; otherwise, the control unit controls the relay in the relay control unit to be non-conductive, so that the adjustable current constant current power supply cannot drive the deep ultraviolet LED lamp beads 8 to emit light. The control unit can also control the luminance of the deep ultraviolet LED lamp beads 8 through the adjustable current constant current power supply. In specific implementation, the control unit controls the output current of the adjustable current constant current power supply to achieve this.

[0052] The monitoring terminal has a digital interface.

[0054] Specifically, the temperature sensor 6 can be a patch type temperature sensor, which is distributed on the copper substrate 7 and the shell 1, and is used to test the surface temperature of each region. When the temperature of a certain region of the copper substrate 7 or the shell 1 exceeds a certain temperature value, the control unit controls the alarm unit to start working, and at the same time transmits the temperature data to the monitoring terminal through the wireless remote data transceiver unit for alarm, and the monitoring terminal controls the deep ultraviolet LED sterilization module to stop working immediately to prevent the deep ultraviolet LED sterilization module from being damaged.

[0055] The current sensor can be a Hall current transformer, which can measure alternating current and direct current, and the range can reach 50A. It is installed on the current output end of the adjustable current constant current power supply, and is used to detect the output current of the adjustable current constant current power supply in real time, so as to provide current data for the monitoring terminal to remotely control the deep ultraviolet LED sterilization module.

[0056] Further, the sensing module further comprises a flow sensor, which includes a water flow sensor or an air flow sensor, and is installed in a pipeline or an air duct for real-time detection of the flow of the pipeline or the air duct. According to theoretical knowledge, the greater the flow, the stronger the required irradiation intensity, and the irradiation intensity is related to the input current. The greater the current, the stronger the irradiation intensity. Therefore, when the control unit obtains that the flow in the pipeline or the air duct becomes larger or smaller, the output current of the adjustable current constant current power supply can be adjusted accordingly, and then the irradiation intensity of the deep ultraviolet LED lamp bead 8 is adjusted, so as to achieve better sterilization effect.

[0057] In a specific embodiment, the number of ultraviolet intensity sensors 5 is four, and the connection lines of the four ultraviolet intensity sensors 5 form a square, so as to realize uniform measurement of the ultraviolet irradiation intensity of the deep ultraviolet LED lamp bead 8 in each region.
