Description

Technical Field

[0001] The present invention relates to the technical field of vehicle-mounted purifiers, and in particular to a vehicle-mounted purification system, a vehicle-mounted air purifier and an automatic control method thereof. Background Art

[0002] With the popularity of cars, the problem of air pollution in cars has received more and more attention. Plastic structure interiors and fuel systems will release various pollutants. Since the car space is relatively small and the car environment is relatively closed, and in most cases the windows and doors are closed, the air in the car is not circulated and it is easy to produce bacteria and odors, which greatly reduces the quality of the air in the car and is not good for human health. If you open the windows or use external circulation while driving, polluted air and floating dust outside the car will enter the car, which is harmful to the human body.

[0003] Existing vehicle-mounted air purifiers, due to their size limitations, are usually only able to filter with simple filters and filters, and it is difficult to remove particulate dust and organic pollution in the air through adsorption. In addition, since the size of air purifiers is generally small, their air intake and air outlet efficiency are low, making it difficult to quickly purify the air in the car, resulting in pollutants in the car still being harmful to the human body. If the air purifier's suction power is simply increased, energy consumption will increase and battery life will be affected. In addition, a large amount of dust and other harmful substances will accumulate in the air purifier after long-term use. If not cleaned in time, it will affect the purification effect and even cause secondary pollution.

[0054] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0055] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a vehicle-mounted purification system and a vehicle-mounted air purifier.

[0056] Embodiment 1:

[0057] A vehicle-mounted air purification system, comprising:

[0058] an air flow path, on which polluted air is purified to obtain fresh air;

[0059] An air quality detection module, comprising an external sensor group and an internal sensor group, wherein the external sensor group is used to detect the air quality index when air enters the system, and the internal sensor group is used to detect the air quality index when air is discharged from the system;

[0060] A flow control module, used to control the air flow per unit time on the air flow path according to the input current power;

[0061] An air purification module, arranged on the air flow path, for gradually purifying polluted air into fresh air;

[0062] A power supply module, used to supply power to the control module;

[0063] The control module is used to control the current power input to the flow control module, and control the current power input to the air purification module according to the air flow rate per unit time on the air flow path, so as to adapt the power of the air purification module to the air flow rate per unit time on the air flow path.

[0064] Embodiment 2:

[0065] See also Figure 1-2 A vehicle-mounted air purifier comprises a shell 1, wherein two purification chambers and a control chamber are arranged inside the shell 1, and air purification modules are arranged inside the purification chambers, and the air purification modules comprise an electromagnetic dust collecting mechanism 3, an air filtering mechanism 4, and a negative ion generator 5 which are arranged in sequence; an air inlet 11 and a symmetrically arranged air outlet 12 are arranged on the surface of the shell 1, and the air inlet 11 is shared by the two purification chambers, and each purification chamber has an air outlet 12; the shell 1 is also connected to a solar panel 2, and an air inlet gap is provided between the solar panel 2 and the air inlet 11; inside any purification chamber, an air flow path is formed between the air inlet 11, the electromagnetic dust collecting mechanism 3, the air filtering mechanism 4, the negative ion generator 5, and the air outlet 12; after the air enters from the air inlet 11, it passes through the electromagnetic dust collecting mechanism 3 in sequence to remove particulate matter, and then passes through the air filtering mechanism 4 to remove small molecular harmful components, and then passes through the negative ion generator 5 to carry negative ions and is discharged from the air outlet 12.

[0066] Therefore, when the solar vehicle purifier is in use, the air in the vehicle passes through the air intake gap between the solar panel 2 and the air intake 11, and enters the interior of the housing 1 from the air intake 11. Inside the housing 1, the air enters two purification chambers evenly from the air intake 11. Inside the purification chamber, the air first passes through the electromagnetic dust collection mechanism 3 to remove large particle pollutants (PM2.5, PM10 and other pollutants) in the air by electromagnetic dust removal. The air after dust removal then passes through the air filter mechanism 4 to remove organic pollutants such as formaldehyde. The air finally passes through the negative ion generator 5, carrying the negative ions generated by the negative ion generator 5, and is finally discharged from the exhaust port 12, so as to circulate and purify the air in the vehicle continuously, maintain the air in the vehicle within a suitable pollutant value, effectively purify the environment in the vehicle, and ensure high-quality breathing of the driver and passengers in the vehicle.

[0067] For further information, see Figure 5 In any purification chamber, a speed measuring fan 13 and a plurality of guide fans 14 are sequentially arranged on the air flow path; the speed measuring fan 13 and the plurality of guide fans 14 both belong to a flow control module, and the speed measuring fan 13 and the plurality of guide fans 14 are used to jointly provide power for air to pass through the air flow path; wherein, as the power of the speed measuring fan 13 and the plurality of guide fans 14 increases, the air flow rate of the air flow path gradually increases.

[0068] Therefore, through the rotation of the speed measuring fan 13 and the plurality of guide fans 14, the air outside the solar vehicle purifier is continuously drawn into the shell 1 through the speed measuring fan 13, and the purified air is discharged from the shell 1 through the continuous exhaust action of the guide fan 14. Through the action of the speed measuring fan 13 and the plurality of guide fans 14, an air flow path is formed inside any purification chamber inside the shell 1, and the air is continuously purified along the air flow path to ensure that the air passes through the entire purification process and effectively ensure the air purification effect. In addition, by controlling the power increase of the speed measuring fan 13 and the plurality of guide fans 14, the air flow rate of the air flow path can be gradually increased, thereby being able to control the purification rate of the solar vehicle purifier within a single time, and then control the efficiency of purifying the air of the entire vehicle to meet the needs of purifying the vehicle's internal air environment under different environments.

[0069] For further information, see Figure 6-8 The electromagnetic dust collecting mechanism 3 includes two electrode nets 31, a vibration component 32, a dust collecting box 33 and a power adjusting component; the electrode polarities of the two electrode nets 31 are always opposite, and the power of the two electrode nets 31 is adjusted by the power adjusting component. The vibration component 32 is used to regularly vibrate the two electrode nets 31 to shake off the dust adsorbed on the two electrode nets 31 respectively, and the dust is enriched by gravity and collected in the dust collecting box 33; the power of the two electrode nets 31 is adjusted by the power adjusting component as the airflow flow rate in the airflow flow path changes.

[0070] The power adjustment member may be an electric control component associated with the speed measuring fan 13, which detects the power of the speed measuring fan and controls the current of the electrode network 31 according to the power of the speed measuring fan, so that the current passing through the electrode network 31 increases or decreases to match the air flow processed in a single moment;

[0071] The power adjustment member may also be a centrifugal force test assembly associated with the speed measuring fan 13 (it may be a slide bar and a small ball sleeved outside the slide bar, and there are completely identical springs on both sides of the small ball, and the change in the magnitude of the centrifugal force is measured by the position offset of the small ball). By testing the centrifugal force, the power of the speed measuring fan 13 is relatively obtained, and the current magnitude to the electrode network 31 is controlled by the movement of the centrifugal force test assembly (reducing the resistance value of the resistor connected in series);

[0072] Then, the increase or decrease of the current of the electrode network 31 is controlled by the power adjustment component to match the air flow processed in a single moment, thereby matching the power of the electrode network 31 with the air flow processed in a single moment, so as to maximize energy saving through power changes to adapt to the different purification rates of the solar vehicle purifier.

[0073] See also Figure 6-8The vibration assembly 32 includes a limit column 321, an electromagnet 322 and two vibration hammers 323; there is magnetic attraction between the two vibration hammers 323, and the magnetic attraction force of the two vibration hammers 323 is smaller than the magnetic repulsion force generated on the vibration hammer 323 when the electromagnet 322 is energized; when the electromagnet 322 is energized, the electromagnet 322 repels the vibration hammers 323 at both ends respectively, and the vibration hammers 323 move along the axial direction of the limit column 321 under the restriction of the limit column 321.

[0074] As a result, when the electromagnet 322 is not energized, the two vibrating hammers 322 attract each other, so that the two vibrating hammers 322 are respectively fitted with the two ends of the electromagnet 322. When the electromagnet 322 is energized, the electromagnet 322 repels the vibrating hammers 323 at the two ends respectively. The vibrating hammers 323 move along the axial direction of the limiting column 321 under the restriction of the limiting column 321, and collide with the electrode mesh 31, causing the electrode mesh 31 to move.

[0075] Among them, preferably, the dust box 33 is provided with an electromagnetic door (using the common electromagnetic opening and closing door in the prior art). When the vehicle-mounted purifier is started, the control module 6 sends an electric pulse to the electromagnet 322 at set intervals. During the time when the control module 6 sends the electric pulse to the electromagnet 322, the flow control module does not work. When the electromagnet 322 continuously receives the electric pulse (continuously performs a cycle of power-off-power-on, and the cycle time interval is within 0.1S), the electromagnetic door opens, and the electromagnet 322 receives the electric pulse and continuously switches between the two states of having magnetism and not having magnetism, thereby driving the vibration hammer 323 to continuously collide with the electrode net 31, so that the electrode net 31 moves, and the dust on the electrode net 31 is shaken off into the dust box 33. After the electromagnet 322 no longer receives the electric pulse, the electromagnetic door of the dust box 33 is closed to prevent the collected dust from entering the air circulation path again and affecting the subsequent purification process.

[0076] Preferably, see Fig.10 The fan blades of the speed measuring fan 13 are provided with connecting contacts 131, and the side panels of the speed measuring fan 13 are provided with contact areas 132. When the connecting contacts 131 are in contact with the contact areas 132, the circuit of the electromagnet 322 is connected, and the electromagnet 322 is energized. When the electromagnet 322 is energized, the movement of the vibration hammer 323 along the limiting column 321 enables the vibration hammer 323 to contact the corresponding electrode net 31. When the electromagnet 322 is intermittently energized, the vibration hammer 323 continuously reciprocates, and intermittent contact is generated between the vibration hammer 323 and the corresponding electrode net 31, so that the corresponding electrode net 31 vibrates.

[0077] Thus, the dust on the electrode net 31 is shaken off by the continuous vibration of the vibration hammer 323 on the electrode net 31, and the dust is collected in the dust collecting box 33 through the action of gravity, so as to achieve the effect of collecting dust. Moreover, since the vibration frequency of the vibration hammer 323 is positively correlated with the rotation speed of the speed measuring fan 13 (the vibration frequency is equal to the number of rotations of the speed measuring fan 13 within 1 second, and the faster the rotation speed, the more rotations of the speed measuring fan 13 within 1 second), the vibration frequency of the vibration hammer 323 is also adjusted with the power of the speed measuring fan 13, so that it can better adapt to the power of the speed measuring fan 13, that is, match it with the processed air flow within a single moment, and adapt to the different purification rates of the solar vehicle purifier.

[0078] Furthermore, a control module 6 is arranged inside the control cavity, and the control module 6 is signal-connected with an external sensor group and a built-in sensor group, and the control module 6 is signal-connected with the air quality detection module; the external sensor group is used to detect the air quality index when air enters the system (i.e., detects the air quality index outside the vehicle-mounted air purifier, i.e., the air quality index inside the vehicle), and the built-in sensor group is used to detect the air quality index when air is discharged from the system (i.e., the air quality index after rigidification); the control module 6 is electrically connected to the speed measuring fan 13, several duct fans 14 and the negative ion generator 5, respectively, and supplies power to the speed measuring fan 13, several duct fans 14 and the negative ion generator 5; the control module 6 controls the power of the speed measuring fan 13, several duct fans 14 and the negative ion generator 5 according to the difference between the air quality index inside the vehicle and the air quality index after purification.

[0079] Among them, the sensors included in the external sensor group and the built-in sensor group include formaldehyde, PM2.5, PM10, VOC, benzene sensors, etc. The external sensor group and the built-in sensor group calculate the air quality index according to the measured pollutant values ​​(the measurement of the air quality index is a common technical means in the prior art and will not be repeated here). The control module 6 controls the power of the speed measuring fan 13, several duct fans 14 and the negative ion generator 5 according to the difference between the in-vehicle air quality index and the purified air quality index to match the air quality inside the vehicle, so as to quickly adjust the in-vehicle air quality to an appropriate value.

[0080] For further information, see Figure 4 , Fig. 9The solar panel 2 includes a light-facing plate 21 and a telescopic connecting column 22. The telescopic connecting column 22 is connected to the light-facing plate 21 by a rotating connecting piece 23. The light-facing plate 21 can rotate around the rotating connecting piece 23 and stay at any angle; the light-facing plate 21 is used to receive sunlight and generate electrical energy, and the light-facing plate 21 is electrically connected to the control module 6; a power-on interface 15 is also provided on one side of the shell 1, and the power-on interface 15 is electrically connected to the control module 6 through a power adapter; the solar panel 2 and the power adapter are both power supply modules, the control module 6 can receive the electrical energy generated by the light-facing plate 21, and the control module 6 can also receive electrical energy by connecting to the power supply in the vehicle through the power-on interface 15.

[0081] Therefore, the light-facing plate 21 can be lifted to a certain height by telescopic connecting column 22, and then the angle of the light-facing plate 21 can be adjusted by rotating connecting member 23 to adapt to different light irradiation positions, so as to obtain greater solar radiation and more solar energy.

[0082] For further information, see Figure 3 The air filtering mechanism 4 includes a plurality of filter elements 41, and the filter elements 41 include one or more combinations of formaldehyde filter elements, benzene filter elements, and VOC filter elements.

[0083] For further information, see Figure 3 The negative ion generator 5 includes a plurality of negative ion nozzles 51 , and the negative ion generator 5 ionizes the air to generate negative ions which are uniformly ejected from the plurality of negative ion nozzles 51 .

[0084] Working principle: When in use, first lift the light-facing plate 21 to a certain height by telescopic connecting column 22, and then adjust the angle of the light-facing plate 21 by rotating connecting piece 23 to adapt to different light exposure positions, so as to obtain greater solar radiation and more solar energy. At the same time, the control module 6 can also connect to the power supply in the vehicle through the power interface 15 to receive electrical energy for power supply.

[0085] The air in the car passes through the air intake gap between the solar panel 2 and the air intake 11, and enters the interior of the housing 1 from the air intake 11. Inside the housing 1, the air enters two purification chambers evenly from the air intake 11. Inside the purification chamber, the air first passes through the electromagnetic dust collection mechanism 3 to remove large particle pollutants (PM2.5, PM10 and other pollutants) in the air by electromagnetic dust removal. The air after dust removal then passes through a number of filter elements 41 of the air filter mechanism 4 to remove organic pollutants such as formaldehyde. The air finally passes through the negative ion nozzle 51 of the negative ion generator 5, carrying the negative ions generated by the negative ion generator 5, and is finally discharged from the exhaust port 12, so as to circulate and purify the air in the car continuously, maintain the air in the car within a suitable pollutant value, effectively purify the environment in the car, and ensure high-quality breathing of the driver and passengers in the car.

[0086] The air quality index is calculated based on the measured pollutant values ​​by the external sensor group and the internal sensor group. The control module 6 controls the power of the speed measuring fan 13, the plurality of duct fans 14 and the negative ion generator 5 according to the difference between the in-vehicle air quality index and the purified air quality index to match the air quality inside the vehicle, so as to quickly adjust the in-vehicle air quality to an appropriate value.

[0087] Through the rotation of the speed measuring fan 13 and the plurality of guide fans 14, the air outside the solar vehicle purifier is continuously drawn into the shell 1 through the speed measuring fan 13, and the purified air is discharged from the shell 1 through the continuous exhaust action of the guide fan 14. Through the action of the speed measuring fan 13 and the plurality of guide fans 14, an air flow path is formed inside any purification chamber inside the shell 1, and the air is continuously purified along the air flow path to ensure that the air passes through the entire purification process and effectively ensure the air purification effect. In addition, by controlling the power increase of the speed measuring fan 13 and the plurality of guide fans 14, the air flow rate of the air flow path can be gradually increased, thereby being able to control the purification rate of the solar vehicle purifier within a single time, and then control the efficiency of purifying the air of the entire vehicle to meet the needs of purifying the vehicle's internal air environment under different environments.

[0088] Among them, the increase and decrease of the current of the electrode network 31 is controlled by the power adjustment member to match the air flow processed in a single moment, so as to match the power of the electrode network 31 with the air flow processed in a single moment, so as to maximize energy saving through power changes to adapt to the different purification rates of the solar vehicle purifier; when the vehicle purifier is started, the control module 6 sends an electric pulse to the electromagnet 322 at set intervals. During the time when the control module 6 sends the electric pulse to the electromagnet 322, the flow control module does not work. When the electromagnet 322 continuously receives the electric pulse, the electromagnetic door is opened. The electromagnet 322 receives the electric pulse and continuously switches between the two states of having magnetism and not having magnetism, thereby driving the vibration hammer 323 to continuously collide with the electrode network 31, so that the electrode network 31 moves, and the dust on the electrode network 31 is shaken off into the dust box 33. After the electromagnet 322 no longer receives the electric pulse, the electromagnetic door of the dust box 33 is closed to prevent the collected dust from entering the air circulation path again and affecting the subsequent purification process.

[0092] Among them, A i is the in-car air quality index detected at time i, A i+kt is the in-car air quality index detected at time kt after the car purifier is turned on at time i, where i and k are both positive integers;

[0093] The air quality index in the car is detected once every t time interval by the external sensor group. At any time i, when the control module measures the air quality index A in the car according to the air quality index in the car i When ≥100, the vehicle air purifier is activated when the air quality level in the vehicle is at or above the level of light pollution;

[0094] Among them, the air quality level can be based on the pollutant concentration limit values ​​of Level I, Level II, Level III, Level IV, Level V and Level VI of the daily average standards of the national air quality standards, namely, Level I: Air Pollution Index ≤50, excellent level; Level II: Air Pollution Index ≤100, good level; Level III: Air Pollution Index ≤150, light pollution; Level IV: Air Pollution Index ≤200, moderate pollution; Level V: Air Pollution Index ≤300, heavy pollution; Level VI: Air Pollution Index>300, severe pollution.

[0095] After the vehicle air purifier is started, the air quality index A in the vehicle is detected by the external sensor group. i+kt When the temperature is ≤45, the control module determines that the vehicle environment is suitable for the driver to breathe, and thus turns off the vehicle air purifier;

[0096] The vehicle air purifier can be turned on and off in real time according to the real-time air quality index in the vehicle, so as to continuously circulate the air in the vehicle to maintain the air quality range suitable for the driver, saving energy while reducing the trouble of personnel operation.

[0097] S2. When the vehicle purifier is started, the built-in sensor group detects the air quality index B of the vehicle purifier every t seconds. j The control module is based on A sampled at the same time i -B j The value of the flow control module is adjusted to adjust the input power P j ;

[0098] Among them, B j is the air quality index of the vehicle purifier at time j, P jis the input power of the flow control module at time j. When i=j, A i and B j The sampling time is the same, where j is a positive integer;

[0099] Among them, the input power P of the flow control module j According to the actual input size, it is divided into three gears: low, medium and high (for example, 50W, 100W, and 200W). The input power P of the flow control module j Control the air flow rate per unit time on the air flow path;

[0100] Thus, according to the same sampling time, that is, when i=j, by measuring the air quality index A before the air enters the vehicle air purifier i And the air quality index B after the air passes through the car air purifier j The numerical difference is used to calculate the amount of air pollutants that need to be processed by the vehicle purifier, so as to match the input power of the flow control module with the amount of air pollutants that need to be purified, so as to quickly optimize the air quality inside the vehicle through power regulation, quickly adjust the air quality inside the vehicle to a range suitable for the driver, speed up the air purification speed inside the vehicle as much as possible, and reduce the discomfort time of the driver;

[0101] Among them, the input power of the flow control module is within the three gears of 50W, 100W, and 200W, which does not exceed the maximum purification capacity of the air purification module;

[0102] Among them, A i -B j The numerical difference of , on the one hand, characterizes the purification efficiency of the air purification module, and on the other hand, characterizes the amount of air pollutants that the air purification module needs to process at that moment.

[0103] S2.1, when (A i -B j )≥150, it is judged that the pollution condition in the vehicle is serious, and the control module provides input power P to the flow control module. j It is high position (200W);

[0104] S2.2, when (A i -B j )≥75, it is judged that the pollution condition in the vehicle is normal, and the input power provided by the control module to the flow control module is in the middle gear (100W);

[0105] S2.3, when 75>(A i -B j ), it is judged that the pollution condition in the vehicle is relatively light, and the control module provides the input power P to the flow control module. j It is low gear (50W);

[0106] S3, when the vehicle purifier is started, the control module j The value of B is used to judge the air purification efficiency of the air purification module. j When the value is greater than 35, it is judged that the air purification module has a large loss in purification efficiency;

[0107] At this time, the control module stops providing input power P to the flow control module j , at this time P j =0; the control module continuously inputs pulses to the electromagnet 322, and the electromagnet 322 drives the vibration hammer 323 to continuously collide with the electrode mesh 31, so that the electrode mesh 31 moves, and the dust on the electrode mesh 31 is shaken off into the dust box 33;

[0108] Among them, when the maximum purification amount of the air purification module is not exceeded, the dust accumulation of the electrode mesh 31 and the failure of the filter element 41 have an impact on the air quality value B after purification by the vehicle air purifier. j The dust accumulation of the electrode mesh 31 and the failure of the filter element 41 will cause B j Reduced; and the air quality value after purification by the vehicle air purifier is below 35;

[0109] At any time (j), B j When the value is greater than 35, it is determined that the air purification module has a large loss in purification efficiency. First, the dust accumulation on the electrode net 31 is cleaned, and the input power to the flow control module is suspended while cleaning to eliminate the influence of the dust accumulation on the electrode net 31 on the purification of the vehicle air purifier.

After completing step S3, the control module provides input power P to the flow control module again. j After time nt, the control module detects the air quality index B of the vehicle purifier at time j+nt. j+nt , determine whether the filter element 41 needs to be replaced, where n is a positive integer;

[0111] When B j+nt When ≥35, the control module determines that the filter element 41 is invalid, and the control module stops providing input power to the flow control module;

[0112] When B j+nt When <35, the control module continues to provide input power P to the flow control module at time j+nt. j .

After nt time, if Bj+nt When <35, it means that removing the dust accumulation of the electrode net 31 is beneficial to the air purification effect, that is, it is judged that the dust accumulation of the electrode net 31 has an impact on the purification efficiency of the vehicle air purifier, and removing the dust accumulation of the electrode net 31 restores the purification efficiency of the vehicle air purifier, so the input power P can continue to be provided to the flow control module. j Continue the air purification process;

[0114] When B j+nt When ≥35, it is determined that the dust accumulation of the electrode mesh 31 is not the reason for the reduced purification efficiency of the vehicle air purifier at this time, and the control module determines that the filter element 41 has failed. The control module stops providing input power to the flow control module, and in actual application, the control module outputs an alarm signal to the outside to prompt the driver to replace the filter element 41 in time to maintain the use of the vehicle air purifier.
