All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The invention provides an ion generating device.
The ion generating device is a device for generating positive and negative plasmas or negative ions of air. For example, in the anion generating device, the device processes the input direct current or alternating current through an EMI processing circuit and a lightning stroke protection circuit, and then the device is subjected to overvoltage current limiting through a pulse circuit; the high-low voltage isolation and other circuits are raised to alternating current high voltage, then pure direct current negative high voltage is obtained after rectification and filtration by special-grade electronic materials, the direct current negative high voltage is connected to a release tip made of metal or carbon element, high corona is generated by using the tip direct current high voltage, a large amount of electrons (e-) are released at high speed, the electrons cannot exist in the air for a long time (the service life of the existing electrons is only nS level), and the electrons can be immediately captured by oxygen molecules (O2) in the air, so that air anions are generated. The high-voltage power generated by the current high-voltage generating device is usually constant DC negative high-voltage power between-6 kV and-8 kV, the input voltage is lower than-6 kV, the concentration of released anions is too low, the concentration of released anions is low, and the negative ion effect is not obvious; when the continuous input voltage is higher than-8 kV, ozone is easy to generate ionization, static electricity accumulation is generated after a large amount of negative ions are continuously released, and the risk of static breakdown of structural members is serious.
In order to solve the above problems, referring to fig. 1 to 5, in an embodiment of the present invention, the ion generating apparatus includes:
a direct current power supply 10;
a high voltage generator 20 connected to the dc power supply 10, the high voltage generator 20 being configured to convert a voltage of the dc power supply 10 and generate a first output voltage and a second output voltage, so as to alternately output at least between the first output voltage and the second output voltage in a first preset period when the ion generating device is operated; wherein the first output voltage is less than the second output voltage; and
an ion release module 30 connected to the high voltage generator 20, the ion release module 30 being configured to operate according to a first output voltage and a second output voltage to generate and release ions.
In this embodiment, the dc power supply 10 is connected to an ac power supply, and converts ac power into dc power; the high voltage generator 20 is connected with the direct current power supply 10 and the ion release module 30, and the high voltage generator 20 is used for converting the connected direct current into high voltage power and outputting the high voltage power to the ion release module 30 so as to provide the ion release module 30 with the high voltage power. The high voltage generator 20 may specifically be a high voltage generating circuit formed by components such as a step-up transformer, a 555 timer, a power switch tube, an inductor, a diode, a capacitor, a resistor, etc., and specifically may be an oscillating circuit formed by the 555 timer, the resistor, the capacitor, and the diode, and the 555 timer outputs a pulse signal to drive the power switch tube to be turned on/off, thereby controlling the electric energy output of the step-up transformer. The high voltage generator 20 may be alternatively implemented as a negative high voltage generator 20 or a positive and negative high voltage generator 20, or a combination of the negative high voltage generator 20 and the positive and negative high voltage generator 20, which is not limited herein. In the negative high voltage generator 20, the negative high voltage generator 20 is connected with the negative ion release module 30, and the negative high voltage generator 20 has a negative high voltage output terminal electrically connected with a negative high voltage input terminal of the negative ion release module 30. In the positive and negative high voltage generator 20, the positive and negative high voltage generator 20 has a positive voltage output terminal and a negative high voltage output terminal, the positive high voltage output terminal is electrically connected with the positive high voltage input terminal of the positive and negative ion release module 30, and the negative high voltage output terminal is electrically connected with the negative high voltage input terminal of the positive and negative ion release module 30. The direct current connected to the high voltage generator 20 may be 32v,25v or 36v, and the values of the first output voltage and the second output voltage are different according to the difference of the ion release modules 30 connected to the high voltage generator 20, that is, the high voltage generated by the high voltage generator 20 may be positive and negative high voltage, or may be negative high voltage, and in the negative high voltage, the negative high voltage may be-2 to-14 Kv. Among the positive high pressures, the positive high pressure may be 0Kv to 15Kv.
When the high voltage generator 20 supplies power to the negative ion discharging module 30, the first output voltage may be set to-2 to-6 Kv and the second output voltage may be set to-8 to-10 Kv. When the high voltage generator 20 supplies power to the positive and negative ion releasing module 30, the first output voltage may be set to 0 to 5Kv and the second output voltage may be set to 10 to 15Kv. In this way, the high voltage generator 20 is caused to alternately output between the first output voltage and the second output voltage when the high voltage generator 20 is operated. In some specific embodiments, the high voltage generator 20 may directly boost the first output voltage to the second output voltage after outputting the first output voltage for a preset time, directly drop the first output voltage after outputting the second output voltage for a preset time, take the first output voltage as a trough, take the second output voltage as a peak, change the first output voltage and the second output voltage in a half sine waveform or a sine-like waveform, or change the first output voltage and the second output voltage in a tooth waveform (triangle wave, sawtooth wave, trapezoid, etc.).
In this embodiment, the number of ion release modules 30 may be one or two, and when one ion release module 30 is provided, the ion release module 30 may be a plasma release module 30 or a negative ion release module 30. When two ion release modules are provided, there may be two plasma release modules 30 or two negative ion release modules 30, or as shown in fig. 5, two ion release modules are respectively a plasma release module 30A and a negative ion release module 30A. The ion generator can be a negative ion release module 30 or a positive and negative ion release module 30, namely a plasma release module 30A, wherein the positive and negative ion release module 30 ionizes air (mainly oxygen) according to high voltage power output by the high voltage generator 20 so as to generate a large amount of positive ions and negative ions, and the positive ions and the negative ions instantaneously release huge energy for neutralizing positive and negative charges in the air so as to enable water molecules to generate positive ions, negative ions, high-energy electrons, active free radicals and the like, and active oxides and charged ions can lead cell membranes or cell walls to be broken, thereby dying or losing reproductive capacity and realizing the aim of sterilization; meanwhile, redundant negative ions float in the air, so that the aims of eliminating smoke, removing dust, eliminating peculiar smell and purifying the air can be achieved. The negative ion generator ionizes the nearby air after receiving the electric energy output by the high voltage generator 20, and generates free ions, so that particle pollutants such as dust in the air obtain charges, namely, the air is ionized to generate negative ions, the negative ions can generate chemical reactions in the air to generate active substances, and bacteria, fungi and other microorganisms in the air are decomposed to realize the sterilization effect, and the generated negative ions can generate strong oxidative active substances, so that the peculiar smell substances in the air can be oxidized and decomposed to play a role in removing peculiar smell; when the concentration of the negative ions reaches a certain value, the negative ions can charge dust in the air, so that the dust is settled. The ion release module 30 generates corresponding ions (equal amounts of positive ions and negative ions, or pure negative ions) according to the first output voltage and the second output voltage that are alternately output. It will be appreciated that the first output voltage is less than the second output voltage, and therefore the ions generated by the ion release module 30 when operating at the first output voltage are less than the ions generated when operating at the second output voltage. The ion release module 30 alternately operates between a first output voltage and a second output voltage so that a higher ion concentration is also produced at lower voltages without producing a significant amount of ozone.
It will be appreciated that, in the ion generating device, a detecting circuit or a sensor for detecting air quality may be further provided, or when the ion generating device is operated based on the requirement of a user, for example, when an on concentration threshold preset by the concentration of the current air particulate matter is detected, it indicates that the current air pollution is serious, at this time, the high voltage generator 20 starts to output from a first output voltage and continuously increases to a second output voltage in a first preset period, and then continuously decreases to the first output voltage in the second output voltage, and is supplied to the ion releasing module 30, so that the ion releasing module 30 operates at the first output voltage and generates ions; the ion release module 30 works with the second output voltage and generates ions to improve the pollution degree of the current air, and the ions sequentially go forward until the concentration of detected particles is smaller than a preset closing concentration threshold or the working time set by a user is reached, so that the voltage output of the ion release module 30 is stopped, and the ion generation device can effectively control the generation amount of ozone and achieve the beneficial effect of ultralow energy consumption under the condition of lower air pollution degree under the condition of higher air purification efficiency.
The ion generating device of the invention is provided with the direct current power supply 10 and the high voltage generator 20, and the voltage of the direct current power supply 10 is converted through the high voltage generator 20 to generate a first output voltage and a second output voltage, so that when the ion generating device works, the first output voltage and the second output voltage are alternately changed and output to the ion releasing module 30 at least in a first preset period, and the ion releasing module 30 works according to the first output voltage and the second output voltage, thereby generating ion bodies and releasing the ion bodies. The ion generating device provided by the invention starts to output from the first output voltage and continuously rises to the second output voltage at least in a first preset period, and then continuously drops to the first output voltage by using the second output voltage to generate ions, so that the ion generating device can effectively control the generation amount of ozone under the condition of higher air purification efficiency, and simultaneously has the beneficial effect of ultralow energy consumption under the condition of lower air pollution level. The invention solves the problems that the ion concentration is low when the voltage output by the high voltage generator 20 is too low, the sterilization and deodorization effects are poor, or a large amount of ozone is generated by easily puncturing air when the voltage is too high.
Referring to fig. 1 and 2, in an embodiment, the high voltage generator 20 is further configured to convert the voltage of the dc power supply 10 and generate a third output voltage, so as to alternately output the first output voltage, the second output voltage, and the third output voltage with the first preset period when the ion generating device is operated; wherein the third output voltage is greater than the second output voltage.
In this embodiment, the relationship among the first output voltage, the second output voltage and the third output voltage increases gradually, that is, the first output voltage < the second output voltage < the third output voltage. Wherein the first output voltage value may be-2 Kv, the second output voltage may be-8 Kv, and the third output voltage may be-14 Kv. The rate at which the first output voltage rises to the second output voltage, the second output voltage rises to the third output voltage, and the rate at which the third output voltage falls to the first output voltage may be set to be the same or may be set to be different, that is, the rate at which the first output voltage rises to the second output voltage is greater than the rate at which the second output voltage rises to the third output voltage, and the rate at which the third output voltage falls to the first output voltage is greater than the rate at which the first output voltage rises to the second output voltage. The first output voltage may be the minimum threshold voltage at which the ion release module 30 can generate ions, the third output voltage may be the maximum threshold voltage at which the ion release module 30 can generate ions most and ozone is likely to occur, and the second output voltage may be the voltage at which the efficiency is relatively high, i.e. the voltage at which ions are generated more and the power consumption is relatively low. By the arrangement, the ion release amount can be effectively improved, the ion propagation distance is increased, the purification amount of particulate matters is improved, meanwhile, the phenomenon of ion accumulation caused by long-time high-concentration ion release can be avoided, the periodic change of voltage is facilitated, and the oxidation risk caused by long-time working at high pressure of the ion release module 30 is reduced.
Further, in the above-described embodiment, the high voltage generator 20 increases from the first output voltage to the second output voltage at a rate at which the unit time t increases by the first voltage value while alternately outputting between the first output voltage, the second output voltage, and the third output voltage at a first preset period;
rising from the second output voltage to the third output voltage at a rate that increases the second voltage value per unit time t;
dropping from the third output voltage to the first output voltage at a rate that drops by a third voltage value per unit time t; wherein the first voltage value is greater than the second voltage value and less than the third voltage value.
In this embodiment, the first voltage value may be-2 Kv, the second voltage value may be-1 Kv, the third voltage value may be-3 Kv, in practical application, the voltage output by the high voltage generator 20 is rapidly increased from-2 Kv to-8 Kv at-2 Kv/t, and then is slowly increased from-8 Kv to-14 Kv at-1 Kv/t, and then is rapidly decreased to-2 Kv at-3 Kv/t after reaching-14 Kv, and as measured by experiments, the average voltage of the ion release module 30 can be increased to-10K, the negative ion release amount is increased by more than 20%, the negative ion propagation distance is increased by more than 30%, and the particulate matter purification amount is increased by more than 10% when the high voltage generator 20 works at the above-change rule periodicity. And the whole high voltage changes in real time, and when the first output voltage, the second output voltage and the third output voltage rise or fall, different speeds are adopted, for example, when the first output voltage, the second output voltage and the third output voltage rise or fall, the speed is higher when the second output voltage is from low voltage to high voltage, the speed is gentler when the third output voltage is from high voltage, the speed is faster when the third output voltage falls, the duration of the low voltage which generates less ions is shorter, the duration of the high voltage which generates more ions is longer, the rising and falling time of the low voltage and the high voltage are reasonably distributed, the ion release amount can be improved, the working efficiency of the ion generating device is high, the energy consumption is reduced, and the energy efficiency ratio of the ion generating device is improved. The invention can effectively solve the problem that the negative ion release amount is insufficient due to long-time trough voltage or the phenomenon of ionization of ozone due to long-time peak voltage, and even breaks down structural members in the ion generating device because the device works at high voltage for a long time.

In the present embodiment, the positive electrode plate 311 and the negative electrode plate 321 have the same shape and size, and are substantially elongated plate-like, although the electrodes may have other shapes. The positive electrode plate 311 and the negative electrode plate 321 can be made of stainless steel materials or aluminum materials, or nonmetallic materials such as aluminum nitride ceramic plates, epoxy resins and the like. The negative electrode 322 may be made of carbon fiber, metal, or other ion-releasing material, and ionizes the air in the vicinity after receiving the electric energy from the high voltage generator 20, and generates free ions, so that the particulate pollutants such as dust in the air obtain electric charges. The positive electrode plate 311 and the negative electrode plate 321 are respectively provided with a voltage interface, which is for convenience in connecting the high voltage, and in particular, the voltage interface may be implemented by using an elastic contact, so that the plug of the high voltage generator 20 may be electrically connected to the positive and negative electrode plates when being connected thereto. When the voltage interface of the positive electrode plate 311 is connected with a positive voltage, positive ions can be ionized from the positive electrode 312, and correspondingly, negative ions can be ionized from the negative electrode 322 when the positive electrode plate 311 is connected with a negative voltage.
The shape of the positive and negative electrodes may be needle-like, saw-tooth-like or conical, and the positive electrode 312 is optionally tooth-like in this embodiment, and the negative electrode 322 is needle-like. The arrangement of the tips of the tooth-shaped positive electrodes 312 can realize concentrated discharge, so that the corona electric field is formed by more easily puncturing air, high-concentration ions can be instantaneously generated, the positive electrodes 312 are opposite to the tips with higher arrangement density on the negative electrodes, a plurality of tip discharge electrodes are realized to one positive electrode 312, and the high-concentration ions formed by the tip discharge electrodes collide with each other for neutralization, so that high-concentration high-energy plasmas are generated. The positive electrode 312 can be arranged into an equilateral triangle or isosceles triangle structure, and the two sides of the triangle structure are equal in length, so that the contact area of the electrode and the air is the same, the left and right discharge is more uniform, the ion concentration difference in the plasma region is small, and the air is more uniform and thorough in sterilization when passing through.

And, the plurality of positive electrodes 312 are arranged in an arrangement of at least 1 per 5 cm on the positive electrode plate 311. A plurality of the negative electrodes 322 having a diameter of 1mm to 1cm;
the plurality of negative electrodes 322 are arranged on the negative electrode plate 321 in an arrangement of at least 4 negative electrodes 322 arranged every 5 cm.
The positive electrode 312, the discharge needle tip and the negative electrode 322 are oppositely arranged, the vertical distance between the positive electrode 312 and the discharge needle tip can be set to be 2 cm-8 cm, and positive ions and negative ions ionized by the two electrodes can be effectively blocked by the arrangement of the positive electrode and the negative electrode at the position of 2 cm-8 cm, so that the neutralization of the two ions is avoided, and the deodorizing and sterilizing effects are improved. Meanwhile, the larger the vertical distance between the two electrodes is, the larger the creepage distance between the two electrodes is, the better the isolation effect is, the distance between the two electrodes cannot be too large, the blocking effect caused by the too large distance is not large, the structure of the ion generating device and the internal structure of the air conditioner indoor unit can interfere, and the air outlet of the air conditioner can be affected. Therefore, the distance between the two is 2 cm-8 cm, so that not only can a better ionization effect be realized, but also stable installation of the structure can be satisfied.
Referring to fig. 3 and 4, in an embodiment, the high voltage generator 20 is specifically configured to convert the dc power supply 10 and generate the first output voltage, and superimpose the dc power supply 10 after converting the dc power supply 10 and generating the pulse power supply to generate the second output voltage.
In this embodiment, the high voltage generator 20 generates the first output voltage by using the basic dc power supply 10, and superimposes the basic dc power supply 10 and the pulse power supply to form the second output voltage, where the first output voltage and the second output voltage are in a toothed waveform output (triangle wave and sawtooth wave), so that an extremely high voltage can be instantaneously formed, the positive and negative electrodes can be instantaneously discharged to release a large amount of plasmas, the high voltage generator 20 can be prevented from maintaining the high voltage output, and atoms in a large amount of oxygen molecules are easily ionized, and the single oxygen atoms and air oxygen molecules are combined to form ozone, so that the ozone concentration is too high, and injury to human body is caused.
Further, in the above-described embodiment, the high voltage generator 20 outputs at a rise and fall rate of 0.1Kv to 5 Kv/ms while alternately outputting the first output voltage and the second output voltage at a first preset period.
In this embodiment, the high voltage generator 20 is configured such that the high voltage generator 20 forms a peak voltage only at the second output voltage and forms a high voltage at the peak section, while most of the high voltage is still at a low voltage, so that ionization breakdown air can be avoided, ozone concentration is low, and the high voltage is more reliable, since the high voltage generator 20 is raised from the first output voltage of 0Kv to 5Kv to the second output voltage of 10 to 15Kv at a rising speed of 0.1Kv to 5 Kv/ms, and then lowered from the second output voltage of 10 to 15Kv to the first output voltage of 0Kv to 5Kv at a falling speed of 0.1Kv to 5 Kv/ms. The experiment shows that the first output voltage of 0-5 Kv is taken as a trough, the second output voltage of 10-15 Kv is taken as a peak, the first output voltage and the second output voltage are in a half sine waveform or a sine-like waveform, or the first output voltage and the second output voltage are in a tooth-like waveform (triangular wave, sawtooth wave, trapezoid and the like) for changing, the concentration of accumulated generated ozone is less than 10ppb in 1 hour, and the space sterilization rate is more than 99 percent in 1 hour. The high-voltage generator changes in a toothed waveform (triangular wave, sawtooth wave, trapezoid and the like) between the first output voltage and the second output voltage, so that the problems that the ion concentration is low when the received voltage of the plasma release module is too low, the sterilization and deodorization effects are poor, or a large amount of ozone is easily generated by puncturing air when the received voltage is too high can be solved.
