[0028] The present invention will be described in detail below with reference to specific embodiments.
[0029] Example 1: Figure 1 、 Figure 3 , Figures 4 and 5As shown, an environmentally adaptive deodorizing and disinfecting air purification device includes a housing 1 having an air inlet 2 and an air outlet 3. A fan 4, an ion charging module 5, and an ion generating module 6 are disposed within the housing. A dust collection filter 7 and a gaseous filter 8 are disposed between the ion charging module 5 and the ion generating module 6. The control circuit includes a microcontroller, a power supply circuit, a fan control circuit, a high-voltage package circuit 1, a high-voltage package circuit 2, and a current detection circuit 1 and a current detection circuit 2; the input and output ends of the microcontroller are electrically connected to the power supply circuit; the power supply circuit is electrically connected to the ion charging module through the high-voltage package circuit 1, the current detection circuit 1 is electrically connected to the microcontroller, and the current detection circuit 1 is electrically connected to the high-voltage package circuit 1; the power supply circuit is electrically connected to the ion generating module through the high-voltage package circuit 2, the current detection circuit 2 is electrically connected to the microcontroller, and the current detection circuit 2 is electrically connected to the high-voltage package circuit 2; the power supply circuit is electrically connected to the fan; the current detection circuit 1 detects the input current value of the high-voltage package circuit 1 and transmits the current value to the microcontroller. After processing, the microcontroller controls the power supply circuit to output a corresponding voltage to the ion charging module through the high-voltage package circuit 1 according to a preset voltage value corresponding to the current value; the current detection circuit 2 detects the input current value of the high-voltage package circuit 2 and transmits the current value to the microcontroller. After processing, the microcontroller controls the power supply circuit to output a corresponding voltage to the ion generating module through the high-voltage package circuit 2 according to a preset voltage value corresponding to the current value.
[0030] The ion charging module uses a DC high-voltage power supply to ionize the gas in the air, thereby charging the aerosol particles suspended in the air. Under the action of the electric field force, they are separated and intercepted from the air by the dust collection filter at the rear end.
[0031] The dust collection filter element can adopt a traditional melt-blown electret filter element or an ESP washable electronic dust collection filter element. The single interception and blocking efficiency can be set by adjusting the filter material grade or the electric field strength between the ESP filter elements, combined with the strength of the front-end ion charging filter element.
[0032] The gas filter element can be used to remove various gaseous pollutants in a targeted manner, such as formaldehyde decomposition agents for long-term decomposition of formaldehyde, long-life TVOC adsorption filter elements, etc. The filter element can be installed or not according to the usage scenario.
[0033] The ion generation module refers to a device that uses a DC high-voltage power supply to simultaneously generate positive and negative ions and release them into the air, further compensating for areas with poor airflow in the corners of the space and supplementing the treatment of dirt on the ground, walls, etc., effectively enhancing the user experience of using the equipment.
[0034] The fan generally uses a low-voltage DC motor and an adaptive wind wheel to ensure uniform airflow, low power consumption, and low noise through each module of the equipment and can be transported a certain distance, fully circulating the indoor airflow to keep the adapted space fresh and clean.
[0035] During operation, the control method is as follows: Current detection circuit 1 detects the input current value of high-voltage transformer circuit 1 and transmits this current value to the microcontroller. After processing, the microcontroller controls the power supply circuit to output a corresponding voltage to the ion charging module through high-voltage transformer circuit 1 according to the voltage preset value corresponding to the current value range. Current detection circuit 2 detects the input current value of high-voltage transformer circuit 2 and transmits this current value to the microcontroller. After processing, the microcontroller controls the power supply circuit to output a corresponding voltage to the ion generating module through high-voltage transformer circuit 2 according to the voltage preset value corresponding to the current value range. The above two voltage preset values were obtained based on extensive experimental results and can keep the ozone generated by the purification device within a safe range and avoid exceeding the standard.
[0036] like Figure 4 、 Figure 5 shown. Figure 4 This is a comparison table of test data of ozone release before and after using this technical solution. The test data before using this technical solution is "before adjustment". When the humidity is 70% or more, the ozone release exceeds 50ppb, which exceeds the standard. The test data after using this technical solution is after the "self-adjustment function". The test is to change the humidity value in the test environment every 30 minutes, from a humidity value of 40% to a humidity value of more than 90%. It can be seen that after using the technical solution of the utility model, automatic control of ozone generation is achieved, and even if the humidity changes, the ozone release can still be stabilized below 20ppb. The ozone release exceeds the standard.
[0037] The above experimental controls only apply to humidity fluctuations. Furthermore, if dust accumulates on the module surface or if the module's dimensions change due to transportation or cleaning, the purification device will automatically prevent excessive ozone emissions during operation. This ensures that the ambient ozone level in the environment is less than 50 ppb during operation, a relatively safe value.
[0038] This utility model controls the amount of ozone released within a certain range and can automatically avoid the risk of excessive ozone by-products.
[0039] In this example, the ion charging module is arranged at the air inlet end, and the ion generating module is arranged at the air outlet end.
[0040] In this example, from the air inlet end to the air outlet end, the ion charging module, the dust collection filter element, the gas filter element, and the ion generation module are arranged in sequence.
[0041] The utility model has a simple structure and is easy and convenient to implement.
[0042] In this example, the power circuit is electrically connected to the fan through the fan control circuit.
[0043] Example 2: This example features an ion charging module located at the air outlet, and an ion generating module located at the air outlet; the ion charging module is closer to the air inlet than the ion generating module. The structure is simple and compact. Other features are the same as in Example 1.
[0044] Example 3: This example is characterized in that, from the air inlet end to the air outlet end, the ion charging module, the dust collection filter element, the gas filter element, and the ion generating module are arranged in sequence. The rest is the same as Example 1.
[0045] Example 4: Figure 2 As shown, the characteristic of this embodiment is that the fan 4 is arranged near the air inlet end. Of course, the fan 4 can also be arranged near the air outlet end. The rest is the same as in embodiment 1.
[0046] Example 5: This example features a fan installed between the gas filter element and the ion generator module. The structure is simple and compact. Other features are the same as in Example 1.

[0049] The above solution can be completed using one or more fans. Depending on the specific air volume and product structure, one or more modules can also be used in combination.
[0050] The utility model has a simple structure and is easy and convenient to implement.
[0051] Example 8: A control method for an environmentally adaptive deodorizing and disinfecting air purification device, wherein a microcontroller stores a plurality of high-voltage package 1 current values to be compared, each of which has a preset voltage value. The microcontroller stores a plurality of high-voltage package 2 current values to be compared, each of which has a preset voltage value. A current detection circuit 1 detects an input current value of the high-voltage package 1 circuit and transmits the current value to the microcontroller. The microcontroller compares the current value with the plurality of high-voltage package 1 current values to be compared stored in the microcontroller, and determines which high-voltage package 1 current value to be compared the current value falls into. Then, the microcontroller controls the power supply circuit to output a corresponding voltage to the ion charging module through the high-voltage package 1 circuit according to the preset voltage value corresponding to the high-voltage package 1 current value to be compared.
[0052] The current detection circuit detects the input current value of the high-voltage transformer circuit 2 and transmits this current value to the microcontroller. The microcontroller compares this current value with multiple high-voltage transformer circuit 2 comparison current values stored in the microcontroller and determines which high-voltage transformer circuit 2 comparison current value the current value falls into. The microcontroller then controls the power supply circuit to output a corresponding voltage to the ion generation module through the high-voltage transformer circuit 2 according to the preset voltage value corresponding to the range of the high-voltage transformer circuit 2 current value. The above preset voltage values are derived from extensive experimental results and can keep the ozone generated by the purification device within a safe range and avoid exceeding the standard.
[0053] The current values to be compared can be determined according to the design. The number of current values to be compared can be determined according to the design requirements. In theory, the greater the number, the more accurate the control.
[0054] like Figure 4 、 Figure 5 shown. Figure 4 This is a comparison table of test data of ozone release before and after using this technical solution. The test data before using this technical solution is "before adjustment". When the humidity is 70% or more, the ozone release exceeds 50ppb, which exceeds the standard. The test data after using this technical solution is after the "self-adjustment function". The test is to change the humidity value in the test environment every 30 minutes, from a humidity value of 40% to a humidity value of more than 90%. It can be seen that after using the technical solution of the utility model, automatic control of ozone generation is achieved, and even if the humidity changes, the ozone release can still be stabilized below 20ppb. The ozone release exceeds the standard.
[0055] The above experimental controls only apply to humidity fluctuations. Furthermore, if dust accumulates on the module surface or if the module's dimensions change due to transportation or cleaning, the purification device will automatically prevent excessive ozone emissions during operation. This ensures that the ambient ozone level in the environment is less than 50 ppb during operation, a relatively safe value.
[0056] The utility model can avoid the problem of excessive ozone concentration caused by dust accumulation on the module surface, changes in air humidity, or changes in the size of the modules due to transportation or cleaning.
[0057] This utility model controls the amount of ozone released within a certain range and can automatically avoid the risk of excessive ozone by-products.
[0058] The utility model adopts independent automatic control on the input voltages of the ion charging module and the ion generating module, so that the input voltage can be used more accurately, which is beneficial to controlling the excessive ozone.
[0059] The utility model can be applied to various air purification equipment.
