[0002] As people's living standards continue to improve, the requirements for air quality are becoming more stringent. In daily life, the popularity of electric air purification equipment with environmental detection, sterilization and disinfection functions is getting higher and higher, and it is widely used in public transportation such as buses, high-speed railways, subways, airplanes and other places.

[0003] When detecting environmental quality, existing air purifiers mainly detect pollutants through built-in sensors. However, on the one hand, the detection of pollutants by existing air purifiers is relatively simple.

[0013] The air purification device also includes: a controller, which is communicatively connected with the driving unit, the sensor array, the substrate humidity detection unit, the first water delivery unit, the second water delivery unit and the display unit respectively.

[0014] The present invention provides an air purification device control method, comprising: detecting multiple pollutants in the air through multiple detection units; judging whether each pollutant exists; if so, keeping the detection unit corresponding to the pollutant open; if not, closing the detection unit corresponding to the pollutant.

[0015] The step "if it exists, keep the detection unit corresponding to the pollutant turned on" also includes: obtaining the existing concentration data of each pollutant through each detection unit; judging whether the concentration data of each pollutant exceeds the first preset value corresponding to each pollutant; if it exceeds, adjusting the power of the drive unit to high gear, if it does not exceed, adjusting the power of the drive unit to low gear.

[0016] After the step of "obtaining existing pollutant concentration data through each detection unit", it includes: judging whether the fluctuation range of the concentration of at least one pollutant exceeds a second preset value; if exceeded, returning to the step of "detecting multiple pollutants in the air through multiple detection units".

[0017] After the step of "obtaining the existing concentration data of each pollutant through each detection unit", it also includes: feeding back the type and concentration data of each pollutant to the display unit.

[0018] After the step of "feeding back the category and concentration data of each pollutant to the display unit", the method also includes: disassembling and placing the detection unit on the array body according to the category and concentration data of each pollutant on the display unit.

[0021] By setting up a sensor array including multiple detection units to perform corresponding detection of different pollutants in the air, the detection range of pollutants in the air purification device is improved. At the same time, the setting of multiple detection units can switch different detection units on and off as needed to save energy while ensuring effective monitoring of air quality. This setting can overcome the problem that the air purifier in the prior art has a relatively single detection of pollutants, and the sensors thereon need to be turned on for a long time, resulting in high energy consumption.

[0022] 2. In the air purification device provided by the present invention, the sensor array further comprises: an array body, on which a plurality of port structures are arranged, and a plurality of the detection units are detachably arranged correspondingly on each of the port structures.

[0026] 4. The air purification device control method provided by the present invention includes, after the step of "obtaining existing pollutant concentration data through each detection unit", determining whether the fluctuation range of the concentration of at least one pollutant exceeds a second preset value; if exceeded, returning to the step of "detecting multiple pollutants in the air through multiple detection units".

[0027] By monitoring the fluctuation range of pollutant concentrations and returning to the air quality category judgment step when it exceeds the preset value, since air quality has multiple representations, if one of the indicators increases significantly, other indicators will usually fluctuate, and then it is necessary to judge the remaining indicators to see whether the detector is normal.

[0034] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0038] like Figure 1 - Figure 3 This embodiment provides an air purification device, including: a purification body and a sensor array, specifically an air purifier, and may also be a humidifier, etc.

[0039] The purification body includes an air inlet 1 and an air outlet 2, and is equipped with a drive unit and a filter unit 3. The drive unit can drive the gas to flow from the air inlet 1 to the air outlet 2. In this embodiment, it is a drive motor with a wind wheel. The filter unit 3 is arranged between the air inlet 1 and the air outlet 2, and can filter pollutants in the flowing gas. Specifically, the filter unit 3 can be selected as needed, such as a PTFE filter, a glass fiber filter, an electrostatic filter, an activated carbon fiber filter, etc. In this embodiment, the filter unit 3 is a metal filter.

[0040] The sensor array is arranged outside the purification body and is connected to the driving unit in communication, specifically electrically or wirelessly, and includes a plurality of detection units 5 that can respectively detect the concentration data of different pollutants in the gas entering the purification body.

[0041] By setting up a sensor array including multiple detection units 5 to perform corresponding detection of different pollutants in the air, the detection range of pollutants in the air purification device is improved. At the same time, the setting of multiple detection units 5 can switch different detection units 5 on and off as needed on the basis of ensuring effective monitoring of air quality, thereby saving energy. This setting can overcome the problem that the air purifier in the prior art has a relatively single detection of pollutants, and the sensors thereon need to be turned on for a long time, resulting in high energy consumption.

[0042] The sensor array also includes an array body 4, which is arranged in a frame shape, and has a plurality of port structures 6 arranged thereon, and a plurality of detection units 5 are detachably arranged on each port structure 6. The number and distribution of the port structures 6 can be adaptively adjusted as needed. This arrangement makes it easy for users to disassemble and assemble the detection units 5 at the corresponding ports as needed, realizes the modular setting of the detection units 5, and enables the detection units 5 to be connected to the array body 4 in the form of plug-ins, so as to realize the addition or replacement of the detection units 5. The array body 4 can also reserve expandable port structures 6 to expand the detection range and detection accuracy of the air purifier for pollutants as needed, and can also effectively remove unnecessary detection units 5 to reduce energy loss.

[0043] As a convertible implementation, the detection units 5 may be provided integrally with the array body 4, with switches of the detection units 5 being provided correspondingly only on the array body 4 or at other locations.

[0044] The detection units include: formaldehyde detection unit, temperature and humidity detection unit, VOC detection unit, PM2.5 detection unit and PM10 detection unit. As a convertible embodiment, the detection unit 5 may include one, two or more detection units 5, or other types of detection units 5 may be provided.

[0045] A green plant cultivation portion 7 is also provided on the top side of the purification body. The green plant cultivation portion 7 is arranged in a groove shape with an opening facing upward, suitable for carrying a cultivation matrix. In this embodiment, the cultivation matrix is ​​soil, and may also be other matrices, such as stones, culture solution, etc.

[0046] The green plant cultivation part 7 is built with a substrate humidity detection unit, which is electrically connected to the driving unit and is suitable for detecting the humidity in the cultivation substrate. In this embodiment, each detection unit 5 is a sensor.

[0047] The purification body is also built with a detachable water holding unit 8, which is specifically a built-in water tank, which is connected to the green plant cultivation part 7 and the air outlet 2 respectively, and is correspondingly provided with a first water delivery unit and a second water delivery unit, the first water delivery unit is connected to the matrix humidity detection unit for communication, and the second water delivery unit is connected to the temperature and humidity detection unit for communication, specifically an electrical connection or a wireless connection, and the first water delivery unit and the second water delivery unit are specifically micro water pumps. This arrangement makes it easy for the purification body to determine whether to supply water to the green plant cultivation part 7 according to the humidity and water content in the cultivation matrix, so as to achieve the effect of beautifying the indoor environment and absorbing carbon dioxide to increase oxygen, and it can also determine whether to supply water to the air outlet 2 according to the humidity and temperature of the external environment, so that the air outlet 2 sprays water mist to achieve the effect of humidification and cooling.

[0048] In this embodiment, the air outlet 2 is arranged on the top side of the purification body, adjacent to the green plant cultivation part 7, and the air inlet 1 is arranged on the side of the purification body.

[0049] In this embodiment, the purification body is arranged in a shell form, and a lateral panel 9 is arranged on the outer side thereof. Preferably, the lateral panel 9 is detachably arranged. Specifically, the lateral panel 9 is arranged on the side of the purification body and corresponds to the upper side of the air inlet 1. A sensor array and a display unit 10 are arranged on the lateral panel 9. The sensor array is arranged along the side of the display unit 10 away from the air inlet 1, that is, on the upper side of the display unit 10. This arrangement makes the sensor array away from the air inlet 1 and arranged in a different direction from the air outlet 2, thereby improving the detection accuracy of each detection unit 5 in the sensor array.

[0050] The air purification device also includes a controller, which is specifically a single chip microcomputer or a PLC, and can be connected to the drive unit, the sensor array, the substrate humidity detection unit 5, the first water delivery unit, the second water delivery unit and the display unit 10 in a communication manner, specifically electrically or wirelessly. As a convertible embodiment, the controller can select only one, two or more structures for communication connection.

[0051] This embodiment also provides an air purification device control method, including: S1. Detecting multiple pollutants in the air through multiple detection units 5; S2. Determining whether each pollutant exists; S3. If it exists, keeping the detection unit 5 corresponding to the pollutant open; if it does not exist, closing the detection unit 5 corresponding to the pollutant. This setting can effectively determine whether different pollutants exist in the environment, and close the detection unit 5 corresponding to the non-existent pollutant, which can achieve energy saving effect.

[0052] Specifically, various pollutants in the air around the purification body are detected through detection units such as the formaldehyde detection unit, temperature and humidity detection unit, VOC detection unit, PM2.5 detection unit and PM10 detection unit in the sensor array of the air purification device. After obtaining the detection results, they are transmitted to the controller, and the controller determines whether various pollutants exist, and returns to control the opening and closing of various detection units based on whether they exist or not.

[0053] Among them, after the step of "if it exists, keep the detection unit 5 corresponding to the pollutant turned on", it also includes: obtaining the existing concentration data of each pollutant through each detection unit 5; judging whether the concentration data of each pollutant exceeds the first preset value corresponding to each pollutant; if it exceeds, adjusting the power of the drive unit to a high gear, if it does not exceed, adjusting the power of the drive unit to a low gear. This setting can adjust the power of the drive unit according to the concentration of the pollutant, and can effectively ensure the filtration and air outlet efficiency under the premise of energy saving.

[0054] In this embodiment, the first preset value may be set in a range of 5% to 30%; preferably, the first preset value is 5%.

[0055] Furthermore, the detection unit detects various pollutants in the air in the environment around the purification body, and obtains the detection results, which are the concentrations of various pollutants. The controller determines whether various pollutants exist, that is, whether the concentrations of various pollutants in the detection results are zero.

[0056] Specifically, in this embodiment, the detection unit detects various pollutants in the air in the environment around the purification body, obtains the concentration of each pollutant and transmits it to the controller. After the controller turns off the pollutant detection unit corresponding to the concentration of zero, it determines whether the concentration of the pollutant corresponding to the non-zero concentration data exceeds the first preset value corresponding to the pollutant, and controls the gear change of the drive unit based on whether it exceeds or not.

[0057] In addition, after the step of "obtaining existing concentration data of various pollutants through various detection units 5", it includes: judging whether the fluctuation range of the concentration of at least one pollutant exceeds the second preset value; if it exceeds, returning to the step of "detecting multiple pollutants in the air through multiple detection units 5". The size of the second preset value can be adaptively determined according to the national standard and other data for the concentration safety value of different pollutants.

[0058] Specifically, the concentration data acquired by the detection unit 5 corresponding to the non-zero concentration pollutant is continuously fed back to the controller. The controller records and monitors the data within the preset time range, determines whether the fluctuation amplitude exceeds the second preset value, and chooses whether to reopen other closed detection units 5 and perform re-detection based on whether it exceeds the second preset value. Furthermore, the preset time can be adaptively adjusted according to the actual situation.

[0059] By monitoring the fluctuation range of pollutant concentrations and returning to the air quality category judgment step when it exceeds the preset value, since air quality has multiple representations, if one of the indicators has a large increase, other indicators will usually fluctuate, and then it is necessary to judge the remaining indicators to see whether the detector is normal, thereby improving detection accuracy.

[0060] After the step of "obtaining the existing concentration data of each pollutant through each detection unit 5", it also includes: feeding back the category and concentration data of each pollutant to the display unit 10 for the user to observe and determine. Specifically, the controller is electrically connected to the display unit 10, and after the controller obtains the concentration data of each pollutant, the controller obtains the category and concentration data of each pollutant, and after data analysis and processing, displays it on the display unit 10 in the form of an image to achieve visual presentation, and continuously provides it within a preset time.

[0061] After the step of "feeding back the categories and concentration data of each pollutant to the display unit 10", the step further includes: removing and placing the detection unit 5 on the array body 4 according to the categories and concentration data of each pollutant on the display unit 10. Specifically, the user can optimize the array body 4 according to the air quality feedback including the categories and concentration data of each pollutant on the display unit 10, and regularly replace the detection unit 5 corresponding to the pollutant that has not appeared for a long time to reduce energy consumption, or add a new detection unit 5 to increase the detection range.

[0062] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention.
