In order to solve the above problems, the present invention provides an improved in-vehicle air quality optimization device, which includes an air quality detection unit, a determination unit and a communication unit, wherein the air quality detection unit is adapted to detect the air quality and includes a detection unit adapted to detect CO in the in-vehicle air2A first detecting subunit of concentration, a judging unit adapted to judge the CO detected by the first detecting subunit2Whether the concentration is higher than a set first threshold value or not, the communication unit is suitable for judging the CO in the judging unit2And sending an air conditioner external circulation ventilation instruction when the concentration is higher than the first threshold value so as to start the air conditioner external circulation ventilation function. After the external circulation ventilation function of the air conditioner is started, fresh air outside the automobile can enter the automobile, so that the CO of the air inside the automobile is reduced2Concentration, alleviating the symptoms of fatigue of the vehicle user.
Correspondingly, the invention also provides an in-vehicle air quality optimization method, which comprises the following steps: detecting CO in air in a vehicle2Concentration; judging the CO2Whether the concentration is higher than a set first threshold value; after judging the CO2And when the concentration is higher than the first threshold value, starting the external circulation ventilation function of the air conditioner. After the external circulation ventilation function of the air conditioner is started, fresh air outside the automobile can enter the automobile, so that the CO of the air inside the automobile is reduced2Concentration, alleviating the symptoms of fatigue of the vehicle user.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
As shown in fig. 1, the in-vehicle air quality optimizing apparatus of the present embodiment includes an air quality detecting unit 5, a judging unit 70, and a communication unit 71. Wherein:
the air quality detection unit 5 is adapted to detect air quality and comprises a first detection subunit 50, the first detection subunit 50 being adapted to detect CO in air in the vehicle2And (4) concentration.
The determination unit 70 is adapted to determine the CO detected by the first detection subunit 502Whether the concentration is higher than a set first threshold.
The communication unit 71 is adapted to determine said CO at the determination unit 702Concentration higher than the first threshold (i.e. the CO in the air in the vehicle)2Concentration exceeds standard), sending an air conditioner external circulation ventilation instruction, and starting an air conditioner external circulation ventilation function according to the air conditioner external circulation ventilation instruction. In the technical scheme of the invention, the air conditioner external circulation ventilation means that the air conditioner is started to make fresh air outside the vehicle enter the vehicle. After the air conditioner external circulation ventilation function is started, fresh air outside the automobile can enter the automobile, so that CO of the air inside the automobile is reduced2Concentration, alleviating the symptoms of fatigue of the vehicle user.
In this embodiment, the first threshold is 1000 PPM. It should be noted that, in the technical solution of the present invention, the size of the first threshold is not limited to this embodiment, and the first threshold may be set according to different requirements of a vehicle user on the quality of air in the vehicle.
In the technical solution of the present invention, when the in-vehicle air quality optimization apparatus is applied to a vehicle, the first detection subunit 50 may be disposed at any position in the vehicle.
In the present embodiment, the first detecting subunit 50 is disposed at a position where the roof of the vehicle faces the seat or is disposed on the seat, that is, the first detecting subunit 50 is located close to the user of the vehicle, so that the first detecting subunit 50 can timely detect CO in the air near the user of the vehicle2Concentration, once CO in the air in the vicinity of the vehicle user is detected2When the concentration exceeds the standard, the communication unit 71 can send the air conditioner external circulation ventilation instruction to allow fresh air outside the vehicle to enter the vehicle, so that the quality optimization device for the air inside the vehicle can optimize CO in the air near the vehicle user2The situation of the concentration exceeding the standard can respond quickly to reduce the CO in the air in the vehicle2Concentration, thereby alleviating fatigue symptoms of the vehicle user.
In this embodiment, the first detecting subunit 50 is CO2A sensor. Optionally, the CO2The detection range of the sensor is 100PPM to 5000 PPM. In other embodiments, the first detection subunit 50 can be other units capable of detecting CO2And a concentration detection device.
As shown in fig. 1 to 2, in the present embodiment, the in-vehicle air quality optimization apparatus further includes a receiving unit 72, a gas flow actuator 2, a first control unit 73, a filter 4, an ionizer 6, and a second control unit 74. Wherein:
the receiving unit 72 is adapted to receive an open air purge command and a terminate air purge command.
The gas flow device 2 is suitable for driving the air in the vehicle to circularly flow, so that the air in the vehicle can be repeatedly purified.
The first control unit 73 is adapted to control the gas flow actuator 2 to operate when the receiving unit 72 receives the command to start air purification, and to control the gas flow actuator 2 to stop operating when the receiving unit 72 receives the command to stop air purification.
The filter 4 is suitable for filtering pollutants in air in the vehicle which circularly flows so as to realize the air purification function of the air quality optimization device in the vehicle. In the technical scheme of the invention, the air purification function refers to filtering out pollutants in the air.
The ionizer 6 is adapted to discharge negative ions to the air inside the vehicle.
The second control unit 74 is adapted to control the ionizer 6 to operate when the receiving unit 72 receives the command to turn on the air purification, and to control the ionizer 6 to stop operating when the receiving unit 72 receives the command to terminate the air purification.
When the air purification function of the in-vehicle air quality optimization device is to be started, the start air purification instruction is sent to the receiving unit 72. When the receiving unit 72 receives the command to turn on the air purification, the first control unit 73 controls the operation of the gas flow actuator 2, and the second control unit 74 controls the operation of the ionizer 6. The air flow device 2 in operation circulates the air in the vehicle and passes through the filter 4, and pollutants in the air passing through the filter 4 are filtered by the filter 4, so that the air in the vehicle is purified. While filtering contaminants in the air, the ionizer 6 releases negative ions into the air to optimize the air quality.
When the air purification function of the in-vehicle air quality optimization device is to be terminated, the termination air purification instruction is sent to the receiving unit 72. When the receiving unit 72 receives the instruction to terminate air purification, the first control unit 73 controls the gas flow actuator 2 to stop operating, and the second control unit 74 controls the ion generator 6 to stop operating, so that pollutants in the air in the vehicle cannot be filtered by the filter 4, and negative ions cannot be released to the air in the vehicle.
In the technical solution of the present invention, the modes of sending the command of opening air purification and the command of terminating opening air purification to the receiving unit 72 are divided into two types: manual mode, automatic mode.
In the manual mode, a switch (not shown) may be disposed in the in-vehicle air quality optimization apparatus, and the start air purification command and the stop air purification command may be sent to the receiving unit 72 after the switch is manually triggered. The switch can be a touch switch (namely, a human hand is required to be in contact with the switch when the switch is controlled to be switched on and off), or can be an induction switch (namely, the human hand is not required to be in contact with the switch when the switch is controlled to be switched on and switched off).
Alternatively, when the manual mode is used, a handheld terminal (e.g., a mobile phone, Ipad) may be used to send the start air purification command and the stop air purification command to the receiving unit 72.
When the automatic mode is adopted, the in-vehicle air quality optimizing device can be set to be in a normally open state, namely, when the vehicle enters the whole vehicle power-on state, the in-vehicle air quality optimizing device starts to work. For example, in the case of a manual shift vehicle, the in-vehicle air quality optimization device starts to operate once a vehicle key is detected to be in a vehicle-powered-on gear.
In this embodiment, the in-vehicle air quality optimization device further comprises a housing 1 having an inner cavity (not identified) that serves as a carrier for the in-vehicle air quality optimization device to carry and protect other components of the in-vehicle air quality optimization device. The housing 1 has an air inlet 12 and an air outlet 11. The gas flow 2, filter 4 and ionizer 6 are all disposed within the interior chamber. The gas flow device 2 is a blower and is fixedly supported in the inner cavity of the housing 1 by a volute 3. When the air purification function of the in-vehicle air quality optimization device is started, as shown by a dotted arrow in fig. 2, the in-vehicle air flows from the air inlet 12 to the inner cavity, then flows into the volute 3 through the filter 4, and finally flows out from the air outlet 11.
In a modification of the present embodiment, the gas flow actuator 2 is a fan. It should be noted that the type of the gas flow device 2 in the present invention should not be limited to the given embodiment.
In the solution of the invention, the housing 1 can be at any position of the vehicle. In the present embodiment, the housing 1 is intended to be fixed to a console box in a vehicle. Specifically, the outer surface of the outer shell 1 is provided with a hinge structure 13, and the outer shell 1 is fixed on the armrest box through the hinge structure 13. Of course, in other embodiments, the housing 1 may be fixed to the console box in other ways.
In a modification of the present embodiment, the housing 1 may also double as the console box, so that the in-vehicle air quality optimizing apparatus is integrated with the console box. It should be noted that in other embodiments, the housing 1 may be disposed at other positions of the vehicle.
In the present embodiment, the pollutants filtered by the filter 4 include PM and NxOyAnd volatile gas, correspondingly, the filter 4 comprises a dust filter layer, an odor adsorption layer, a volatile gas adsorption layer and a sterilization layer to filter out the pollutants.
The PM is particles and comprises PM10, PM2.5 and the like, and the volatile gas comprises formaldehyde, benzene, acetone and other harmful gases generated by interior decorations. It should be noted that, in the technical solution of the present invention, the types of the pollutants and the structure of the filter 4 are not limited to the given embodiment, and the structure of the filter 4 may be correspondingly set according to the requirement of the air purification function of the in-vehicle air quality optimization device.
As shown in fig. 1, in the present embodiment, the air quality detecting unit 5 further includes a second detecting subunit 51 and a third detecting subunit 52. The second detection subunit 51 is adapted to detect the PM concentration in the air, and the third detection subunit 52 is adapted to detect the N in the airxOyAnd (4) concentration.
The judging unit 70 is further adapted to judge whether the PM concentration detected by the second detecting subunit 51 is higher than a set second threshold, the N detected by the third detecting subunit 52xOyWhether the concentration is higher than a set third threshold value or not so as to judge the PM and N in the airxOyWhether the concentration exceeds the standard or not.
The communication unit 71 is further adapted to: the CO is judged by a judging unit 702The concentration is lower than the first threshold value (namely CO in the air in the vehicle)2Concentration does not exceed the standard), and when the PM concentration is higher than the second threshold value, sending an air conditioner internal circulation ventilation instruction.
Alternatively, the communication unit 71 is further adapted to: the CO is judged by a judging unit 702Concentration is lower than the first threshold, and the NxOyAnd sending an air conditioner internal circulation ventilation instruction when the air conditioner internal circulation ventilation instruction is higher than the third threshold value. And according to the air conditioner internal circulation ventilation instruction, the air conditioner internal circulation ventilation function can be started.
In the technical scheme of the invention, the air conditioner internal circulation ventilation means that the air conditioner is started to enable air in the vehicle to circularly flow and air outside the vehicle cannot enter the vehicle.
The PM concentration is higher than the second threshold value, NxOyWhen at least one condition higher than the third threshold value is met, the air pollution degree is relatively heavy, and at the moment, the air with relatively heavy pollution outside the vehicle can be prevented from entering the vehicle by starting the internal circulation ventilation function of the air conditioner, namely, pollutants outside the vehicle are isolated.
Preferably, when the communication unit 71 sends the air conditioner internal circulation ventilation instruction, the window is controlled to be in a closed state, so that air with heavy pollution outside the vehicle is prevented from entering the vehicle from the window, and pollutants outside the vehicle are isolated. The window may be controlled to be in the closed condition manually. Alternatively, when a window controller for controlling the electrical opening and closing of the window is provided on the vehicle, the window may be controlled to be in the closed state by sending a window closing command to the window controller at the same time as the communication unit 71 sends the air-conditioning internal circulation ventilation command.
