Description
Technical Field
The invention relates to an air purifier applied to an automobile.
Background
The high concentration negative ion air purifying function and the negative ion health care and treatment function have been proved by medical science. Chinese patent document CN 106379141A proposes to embed anion generating device in car sun visor, thus in this patent document, can provide high concentration anion for driver and passenger, not only can excite spirit, not easy to fatigue and sleepy, thus reduce the probability of occurrence of traffic accident; meanwhile, in the patent document, high-concentration anions emitted by an anion emitter integrated with the automobile sun visor directly act on the face of a driver and a passenger to form an anion protection barrier on the face of the driver and the passenger, and the principle of anion air purification is applied to improve the air quality near the face of the driver and the passenger; in addition, scientific medical practice proves that the high-concentration negative ions are inhaled, so that the diseases of seven systems such as human breath, circulation and the like can be improved.
At present, various vehicle-mounted air purifiers are known, and a fan is used for purifying by adding a filter screen or simultaneously adding an anion purification mode, and generally have the functions of anion purification and aromatherapy deodorization, and mainly have three installation modes of being placed on an instrument desk, an air outlet of an air conditioner or a cup holder.
With the increasing emphasis on air pollution nowadays, the demands of drivers and passengers on air purification in vehicles are also becoming urgent. The installation space of the cab is relatively narrow, and with the development of automobile electronic technology, the space value of the cab is also higher and higher. It is therefore a trend to integrate in-vehicle electronic devices.
Traffic jam is now a commonplace phenomenon throughout the day of urban traffic conditions, and under traffic jam and waiting for a red light, drivers and passengers mostly start in-car entertainment systems to carry out entertainment, and electronic devices generate a large amount of charged particles, usually positive ionic particles, during operation, and the in-car has to be equipped with a negative ion generator to resist attack of these positive ions.
However, in the environment full of positive ions, the characteristics of short deactivation period and short acting distance of negative ions determine that most of the existing vehicle-mounted negative ion products on the market at present become conceptual products. Because the automobile instrument desk is far away from a driver, anions generated by the low-power anion generators of the vehicle type are difficult to be absorbed by the respiratory system of a driver due to short emission distance, and the action distance is short, the action range of the general vehicle-mounted anion air purifier is limited, and air inhaled by the driver cannot be cleaned.
Chinese patent document CN105756749a proposes a vehicle-mounted negative ion plate anode plate employing an array of negative ion anode pins, and a high-voltage insert sheet, the array-based negative ion anode pins being essentially used to generate positive ions in a wash train by increasing the emission concentration of negative ions. However, the overall module has a large emission power, resulting in a low emission power of the single emission head, in other words, if the emission power of the overall module is reduced, the emission power of the single emission head is reduced more, thereby reducing the dispersion capability and shortening the working distance.

Detailed Description
Referring to fig. 5 of the specification, an electrical schematic diagram of an electrical part of an automotive sunshade plate type air purifier in an embodiment of the present invention is shown, in which a conventional part is an oscillating circuit part for generating an ac signal, a transformer T for boosting (a primary coil of the transformer T forms a coil of the oscillating circuit, or an inductive element, a secondary coil of the transformer is an output coil), and then a rectifying circuit part formed by diodes D2 and D3 rectifies an output of the secondary coil, and further a filter circuit formed by capacitors C3 and C4 filters the rectified electrical signal to finally form a dc negative pulse high voltage (5 kilovolts to 1 kilovolt), and is connected to a transmitting head F through a protection resistor R3, and discharge on the transmitting head F is directed to air discharge to generate negative ions.
The oscillating circuit is a core of the anion generator, the core of the oscillating circuit is a primary coil of a capacitor C1 and a transformer T connected in series with the capacitor C1, and other components, such as a current limiting resistor R2, are added.
The anion generator can be powered by a USB switching power supply supplied by mains supply, and can also be powered by a battery which is a rechargeable battery. In the embodiment of the invention, since the main structure of the automobile sunshade plate type air purifier is assembled on the automobile sunshade plate, the used components should be as small as possible, as to the power supply part, the automobile power supply is used as much as possible, only the power supply wire is needed to be introduced, and in the main flow automobile type, the sunshade plate is commonly provided with a direct current 12V wiring, especially for some high-grade automobile types, the configured sunshade plate is an electric sunshade plate, and the direct current 12V automobile power supply can be directly introduced.
The automobile sun shield is generally arranged above a driver and a copilot head of an automobile cab and is mainly used for shielding direct sunlight from the front upper part, and the integral structure is a plate structure.
The automobile sun shield is generally installed through the pin shaft 1, so that the automobile sun shield can rotate by taking the pin shaft as an axis, some automobile sun shields can be turned up and down, some automobile sun shields can be turned left and right, but no matter which turning mode is adopted, the main effect is to shield sunlight, so that a certain area of the upper part of a front windshield can be shielded after the automobile sun shield is turned down, and the automobile sun shield has definite upper and lower states after being put down, as shown in fig. 1, the side where the pin shaft 1 is located is upper, and the side opposite to the side is lower.
In addition, although the automobile sun visor is mostly of a plastic structure, as the number of integrated functions of the automobile increases, the internal space of the automobile sun visor is also utilized, so that some electric devices are integrated in some automobile sun visors, and therefore, the negative ion generator 6 in the embodiment of the invention can directly reuse the power lines of the electric devices.
In some car sun visors, in order to improve the overall strength, there is often an internal skeleton structure, such as the grid structure shown in fig. 1, typically a metal mesh board, which has conductivity, and even if other electric devices are not integrated, the connection between the metal internal skeleton 3 and the metal pin shaft 1 can be utilized for external connection.
Fig. 1 shows a general structure of a car sun visor having a relatively simple structure, wherein the surface of the car sun visor is provided with a decorative outer skin layer 2, an inner lining layer 8 is generally arranged in the outer skin layer 2, and the inner lining layer 8 is generally a sponge layer, so that the touch feeling of the car sun visor is relatively soft. Inside the accommodating structure formed by the inner liner layer 8 and the outer skin layer 2 is an inner framework 3, and the inner framework 3 mainly enables the automobile sun visor to have given strength.
In some applications, the endoskeleton 3 is configured with a rim 5.
Fig. 5 shows the electrical principle of the negative ion generator, for the oscillating circuit of the negative ion generator, a gain circuit is connected in series for the oscillating circuit, the triode Q1 in fig. 5 is the basic element of the amplifying circuit, the amplifying circuit constructed by a single triode Q1 is the most basic amplifying circuit in the analog circuit, and the most basic amplifying circuit can achieve the purpose, and based on other types of amplifying circuits, the corresponding purpose can be better achieved, therefore, the following description is made with the most basic amplifying circuit, and the person skilled in the art adopts other types of amplifying circuits for the most basic amplifying circuit, thereby achieving the better purpose and having predictability.
In fig. 5, the emitter and collector of the transistor Q1 are connected in series to the oscillating circuit of the negative ion generator, and the base of the transistor Q1 is greatly changed by a slight change in the base voltage, as is known from the general knowledge in the field of electronics.
The transistor Q1 is also a switching transistor, and its base electrode corresponds to a switch, and also corresponds to a valve for controlling the opening of the valve, and the transistor Q1 is used as a switch for controlling the on/off between the emitter electrode and the collector electrode, and is used for controlling the gain of the current between the emitter electrode and the collector electrode when it is used as a control terminal for controlling the opening of the valve.
Accordingly, in the field of electronics, gain is amplification.
The control terminal of transistor Q1, i.e., its base, is led from the sun visor of the vehicle through an isolation capacitor C2 and a protection resistor R4 to steering wheel 12, as shown in fig. 5.
For the automotive technical field, it is understood that the steering wheel itself integrates a plurality of control terminals, such as various control keys of a speaker button, and thus has a mature wiring structure inside.
The base lead of the triode Q1 shown in fig. 5 is electrically connected to the metal inner container of the steering wheel, a coupling capacitance is generated between the metal inner container and the palm of the driver, and when the driver holds the steering wheel, the steering wheel is pressed to enlarge the coupling capacitance, and accordingly, the base voltage is increased, so that the emission power of the anion emission head 7 is increased.
In an embodiment of the present invention, the vehicle body may be utilized directly, independent of the wiring harness, and the vehicle frame is a metal material although the vehicle body is not entirely a metal body, with the control end of the booster circuit being connected from the metal housing portion of the vehicle body to the steering wheel 12.
The negative ions are coupled to the palm of the driver, so that the human body becomes a positive electrode body, and the negative ions move to the positive electrode body based on the electric field effect, so that dispersion of the negative ions is more directional. It is also possible to have a longer dispersion distance under the same power.
In addition to the changes in transmit power produced by human activity, control of the air quality in the cab may also be based on closed loop control. An air quality detection module is arranged in the cab, mainly a negative ion concentration detection sensor or other types of sensors, such as a carbon dioxide sensor, and then the control of the air quality in the cab is realized based on closed-loop control.
Regarding human activity and closed loop control, the two control circuits can be mutually exclusive, i.e. the two control circuits can be mutually exclusive, and a change-over switch can be adopted to realize the mutually exclusive use of the two circuits, such as a single-pole double-throw switch.
Human activity and closed loop control may also coexist to compensate for each other.
Meanwhile, it is understood that the negative ion generator 6 may be configured with a separate switch. The switch may be provided on the steering wheel or on the sun visor.
Furthermore, the control portion of the negative ion generator 6 may be integrated onto the in-vehicle touch panel according to actual needs.
Accordingly, for power adjustment, a control panel may be provided for the negative ion generator 6, and the control panel may be integrated into a vehicle-mounted touch screen or a control panel, or a separate control panel may be provided for the negative ion generator 6.
In some embodiments, a relatively simple power adjustment method of adjustment may also be configured, such as a rotary capacitor-based knob.
In the structure shown in fig. 1, there are 4 anion emitting heads 7, and are arranged along the lower edge of the car sun visor, the anion emitting heads 7 can be arranged in an inclined manner, and the inclined direction is the direction of the anion emitting heads 7 towards the head of the driver when the car sun visor is put down.
In some embodiments, the anion emitter 7 may be provided with two groups, one group is shown in fig. 1, and the other group is the edge nearest to the driver after the car sun visor is retracted, so that the car sun visor does not need to be put down.
The two groups of negative ion emission heads 7 are mutually exclusive. Mutual exclusion is typically implemented using a transfer switch, but other mutual exclusion circuits may be implemented.
For this purpose, in a preferred embodiment, a signal transmitting module connected with an ECO system of the automobile is provided, the ECO system can detect the working state of the engine, the transmitting module transmits the state signal of the engine detected by the ECO system to the controller through the signal receiving module, and when the engine is in a stop state, the controller sends a signal to control the negative ion generator to stop working, so that potential safety hazards caused by the fact that the negative ion generator works in flammable and explosive places such as a gas station are avoided.
