[0037] Below, in conjunction with specific drawings, a disinfection device provided in an embodiment of the present application is described in detail.
[0038] The present application provides a disinfection device that can be used in the field of disinfection technology. Specifically, the disinfection device can be used to disinfect the air in the refrigerator. Figure 1 , a disinfection device provided in the embodiment of the present application mainly includes:
[0039] Power module, communication module, air detection module, plasma disinfection module, fan and microprocessor module;
[0040] Wherein, the communication module, the air detection module, the plasma disinfection module, and the fan are connected to the microprocessor module, and the power supply module is used to power the communication module, the air detection module, the plasma disinfection module, the fan, and the microprocessor module;
[0041] The communication module is used for remote communication connection with an external terminal device, the air detection module is used to detect the air quality data in the refrigerator, the plasma disinfection module is used to perform disinfection operations, the plasma disinfection module includes an air outlet, and the fan is arranged at the air outlet.
[0042] In an embodiment of the present application, a disinfection device is provided, which may include a power module, a communication module, an air detection module, a plasma disinfection module, a blower, and a microprocessor module. The power module can be used to power the other modules and devices. A power switch can be provided on the power module to start and shut down the disinfection device. In an embodiment of the present application, the output voltage level of the power module can be set according to actual needs, for example, it can output a voltage of 5V, 12V, or 24V, etc., and this application does not limit this.
[0043] In an embodiment of the present application, the communication module in the disinfection device can be used for remote communication connection with an external terminal device, that is, when the disinfection device is placed in a refrigerator for use, it can be connected to the disinfection device through other terminal devices (such as the user's mobile phone), thereby transmitting relevant instructions to the disinfection device and reading and monitoring the working condition of the disinfection device. Specifically, in an embodiment of the present application, the type of communication module can be set according to actual needs. For example, it can be set to a cellular network module, such as using 3G / 4G / 5G technology; in some embodiments, it can also be set to a wifi module, a Zigbee module or a Bluetooth module. These modules have many applications in the prior art. This application can directly use mature components to build a communication module, and specifically can adopt one or more of the communication technologies.
[0044] In an embodiment of the present application, the air detection module is used to detect the air quality data in the refrigerator. It may include a variety of gas sensors, such as a carbon dioxide sensor, an ozone concentration sensor, a volatile organic compound sensor, an oxygen sensor, an ammonia sensor, etc. The concentration data of various gases obtained by detection can facilitate the microprocessor module to determine whether disinfection operations are currently required in the refrigerator. For example, in some scenarios, a comparator can be provided in the microprocessor module, and the concentration data of volatile organic compounds detected can be transmitted to the microprocessor module. By comparing it with a set threshold value, it can be determined whether a disinfection operation is currently being performed. In addition, in an embodiment of the present application, the detected air quality data can also be transmitted to the terminal device through the communication module for display, so that the user can understand the situation in the refrigerator in a timely manner.
[0045] The plasma disinfection module can be used to perform disinfection operations. In the embodiment of the present application, the plasma disinfection module utilizes dielectric barrier discharge (DBD) technology, which is a plasma technology that is generally used to generate non-thermal plasma. This technology generates a local discharge phenomenon in the dielectric layer between the electrodes by applying a high voltage between two electrodes. These discharges can produce a large amount of active substances, including positive and negative ions. These positive and negative ions have strong chemical activity and can inactivate microorganisms through various mechanisms, thereby achieving disinfection operations. In the embodiment of the present application, a relatively low temperature plasma can be used. Compared with chemical disinfectants, the plasma disinfection method is safer for the human body and does not produce harmful residues. Moreover, the energy consumption of the module is relatively low, and it is suitable for long-term continuous operation.
[0046] Specifically, in some embodiments, the plasma disinfection module may include a plasma generating unit and a control unit. The plasma generating unit includes a plurality of positive electrode sheets and negative electrode sheets, and the positive electrode sheets and the negative electrode sheets are alternately arranged. For example, in some embodiments, 5 positive electrode sheets and 4 negative electrode sheets may be provided, and the present application does not limit their specific number. The control unit may be used to realize the drive of the plasma generating unit. Specifically, it may include a power tube gate drive circuit and a step-up transformer. The input end of the power tube gate drive circuit may be connected to a microprocessor module. When a disinfection operation is required, the microprocessor module may output a signal of a certain frequency. The output end of the power tube gate drive circuit is connected to a step-up transformer. The step-up transformer has a step-up capability and can increase the output voltage. After being stepped up by the step-up transformer, a higher voltage square wave is produced. The first secondary port of the step-up transformer is the positive output, which can be connected to the positive electrode sheet. The second secondary port is the negative output, which can be connected to the negative electrode sheet, thereby generating a voltage difference between them, which can achieve uniform discharge of the air between the media under atmospheric pressure. The discharge process produces a large number of positive and negative ions, thereby achieving air disinfection.
[0047] In the embodiment of the present application, the plasma disinfection module includes an air outlet, and a fan can be installed at the air outlet. When the disinfection equipment is activated, if the plasma disinfection module performs a disinfection operation, the microprocessor module can synchronously control the fan to discharge the purified air. The fan speed of the fan can also be adjusted to a certain extent to adjust the disinfection intensity. In the embodiment of the present application, an air volume detection module can be provided to facilitate the microprocessor module to adjust the fan speed of the fan.
[0048] For the microprocessor module, it may include a single-chip microcomputer chip, a reset circuit, a crystal oscillator source circuit and a power-down detection circuit, wherein the single-chip microcomputer chip can be set to an STC12 series single-chip microcomputer chip or an STM32 series single-chip microcomputer chip. Of course, the specific chip selection can be flexibly adjusted as needed, and this is not limited in the embodiment of the present application. Specific related circuits can be realized with reference to prior art, and the application will not go into details about this.
[0049] In some embodiments, the disinfection device of the present application may also include a wireless charging module, which can be connected to the power module. The disinfection device can be charged through a wireless magnetic charging mode without the need for a related wiring harness, making it convenient for use in a refrigerator. In addition, in the embodiments of the present application, a battery management module can also be provided to manage the battery charging process, monitor the transition from constant current charging to constant voltage charging, and fully charge the battery. The module has a protection circuit to ensure battery overvoltage protection, overcurrent protection, reverse connection protection, over-discharge protection, overcharge protection, etc. This application does not limit this.
[0050] In some embodiments, the disinfection equipment of the present application may also include a temperature detection module, a status display module and a protection detection circuit. Among them, the temperature detection module can detect the operating temperature of the disinfection equipment in the refrigerator and during charging, and feed it back to the terminal device, thereby monitoring the operation of the disinfection equipment. The status display module can be used to display the real-time status of the on and off status, disinfection operation status, sleep status, battery power, disinfection intensity level, and fault status display to achieve human-computer interactive display. The protection detection circuit can suspend the operation of the disinfection equipment after detecting a fault state in which the plasma disinfection module does not work, is disconnected, the electrode current is too large, the voltage is too high, or there is a foreign object discharge, thereby reducing possible losses.
[0051] A disinfection device provided in the embodiments of the present application has at least the following advantages:
[0052] 1. This application mainly solves the problem of different disinfection capabilities: with traditional refrigerator-type ozone disinfection and ultraviolet disinfection, users may smell the ozone or be harmed by ultraviolet radiation. Moreover, ordinary refrigerator-type disinfection equipment only inhibits the growth of bacteria and may not be able to effectively treat different types of pollutants, such as bacteria, viruses, odors, etc. This may lead to inadequate local cleaning and inadequate air disinfection effect in the refrigerator. Using plasma disinfection, the disinfection range is between the electrode plates, and the fan is used to circulate the air, continuously flowing the air through the electrode plate area, which can achieve full coverage of the refrigerator.
[0053] 2. This application significantly reduces consumables: Disinfection products on the market often use large amounts of consumables and are rarely used in many applications. The disinfection effect is limited in larger refrigerators, and batteries, filters, and cleaning equipment consumables often require replacement, significantly reducing disinfection efficiency. This application, however, produces no consumables or hazardous substances.
[0054] 3. Repair and replacement costs: Refrigerator-type disinfection products on the market have relatively low stability and functionality, and are extremely prone to failure. If they break, the cost of repair is almost the same as replacing a new one. This not only increases costs but also creates a burden on the environment. This application has undergone aging testing, stability testing, and charge-discharge testing before leaving the factory.
[0055] 4. Low-temperature effect and battery life quality: Traditional ozone disinfection, ultraviolet and other air disinfection devices may have greatly reduced battery life and efficacy in low-temperature environments. They do not consider the hardware and usage environment of the equipment. Some devices in low-temperature environments have not undergone strict certification and there is a risk of substandard performance, making it difficult for consumers to distinguish the authenticity.
[0056] 5. Insufficient stability in low-temperature environments: Refrigerator-type disinfection equipment on the market is set to operate in a suitable temperature environment, and does not take into account the temperature environment changes and refrigerator equipment failure sensitivity of the refrigerator. As long as the temperature setting of the refrigerator equipment is adjusted incorrectly, the temperature will drop to a low level and the equipment will freeze and malfunction. The application of this application can withstand a wider temperature range and improve operational stability.
[0057] In an embodiment of the present application, a refrigerator is provided, comprising the aforementioned disinfection device. The refrigerator can be used in the following scenarios:
[0058] 1. Medical and health field: It can be used in hospitals, clinics, laboratories, pharmacies and other places as a medicine fresh-keeping cabinet. It has a very good disinfection and sterilization effect for some spaces that need to be sealed and absolutely fresh.
[0059] 2. Home environment: It can be used in homes, offices, schools and other places as a food preservation cabinet. It has a good preservation function for some foods that are quickly oxidized and easily corroded, and can eliminate the breeding of pathogens to a large extent. It has a good preservation and anti-corrosion effect on bananas, strawberries, cut apples, etc.
[0060] Of course, the actual application scenarios are not limited to the examples given above, and this application does not impose any restrictions on this.
[0061] Throughout this specification, references to terms such as "one embodiment," "another embodiment," or "certain embodiments" indicate that a specific feature, structure, material, or characteristic described in conjunction with an embodiment or example is included in at least one embodiment or example of the present invention. In this specification, schematic representations of these terms do not necessarily refer to the same embodiment or example.
