Referring to fig. 1 to 6, in an embodiment of the present invention, the air purification apparatus includes a purification module 10, an ionizer 20, and a high voltage pack assembly 30, where the high voltage pack assembly 30 includes:
the input end of the high-voltage generator 31 is connected to a direct-current power supply VCC, and the output end of the high-voltage generator 31 is electrically connected with the purification module 10 and the ion generator 20 respectively;
a microswitch 32, wherein the microswitch 32 is arranged between the input end of the high voltage generator 31 and the direct current power supply VCC in series; wherein the content of the first and second substances,
the microswitch 32 is configured to be turned off when the purification module 10 is taken out from the air purification apparatus and triggered by the purification module 10, so that the high voltage generator 31 stops supplying power to the purification module 10 and the ionizer 20.
In this embodiment, the high voltage generator 31 is configured to convert the accessed direct current into high voltage and output the high voltage to the purification module 10 and the ionizer 20, so as to provide a high voltage power supply for the purification module 10 and the ionizer 20. The high voltage generator 31 may specifically adopt a high voltage generating circuit formed by components such as a step-up transformer, a 555 timer, a power switching tube, an inductor, a diode, a capacitor, a resistor and the like, and specifically may form an oscillating circuit by the 555 timer, the resistor, the capacitor and the diode, and the 555 timer outputs a pulse signal to drive the power switching tube to be turned on/off, thereby controlling the electric energy output of the step-up transformer. The high voltage generator 31 may be implemented by a negative high voltage generator 31 or a positive and negative high voltage generator 31, which is not limited herein. In this embodiment, the negative high voltage generator 31 is taken as an example, the negative high voltage generator 31 has a negative high voltage output terminal and a zero voltage output terminal, the negative high voltage output terminal is electrically connected to the negative high voltage input terminal of the purification module 10 and the negative high voltage input terminal of the ion generator 20, respectively, and the zero voltage output terminal is connected to the zero voltage input terminal of the purification module 10. The direct current connected to the high voltage generator 31 may be 32V, 25V or 36V, and the high voltage generated by the high voltage generator 31 may be about-8K. The dc power VCC may be a dc power output from a main control board in the air conditioner, or may be an independent dc power VCC for supplying power to the high voltage generator 31. In this embodiment, the high voltage generator 31 may provide a high voltage power to the purification module 10 and the ionizer 20 upon receiving a control signal from the main controller and when the micro switch 32 is in a closed state, based on the control of the main controller inside the air conditioner.
In this embodiment, the ionizer 20 may be made of a material capable of releasing ions, such as carbon fiber and metal, and ionizes nearby air and generates free ions after receiving the electric energy output by the high voltage generator 31, so that particulate pollutants, such as dust, in the air can obtain electric charges. The ionizer 20 may be generally configured as an anion generator 20 to generate anions that can be automatically adsorbed on particulate pollutants such as dust in the air, thereby completing the charging process of the particulate pollutants, so that the particulate pollutants in the air passing through the anion generator 20 are negatively charged. Of course, in other embodiments, the ionizer 20 may be a positive ionizer 20 that generates positive ions, or a hybrid ionizer 20 that generates positive ions and negative ions, without limitation.
In this embodiment, the purification module 10 may be implemented by an electrical purification module composed of two electrode plates with different electrodes, i.e., an adsorption plate and a repulsion plate, specifically, the adsorption substrate may have an electrical property opposite to the ion charge generated by the ionizer 20, the repulsion plate may have an electrical property the same as the ion charge generated by the ionizer 20, and the purification module 10 maintains an electric field sufficient for ionizing the gas after receiving the high-voltage direct current generated by the high-voltage generator. The dust is ionized by the ionizer 20 and then charged, and the dust with different charged polarities moves to the electrode plates with different polarities respectively under the action of the electric field force and is deposited on the electrode plates of the purification module 10, so that the purpose of separating the dust from the gas is achieved. Of course, the purification module 10 can also be a common filter screen, which can filter out large particles in the air. In addition, the purification module 10 can also be a combination module of an electrical purification body and a filter screen, that is, the purification module 10 includes the electrical purification body and the filter screen which are stacked along the air inlet direction, optionally, the filter screen is arranged on the air inlet side of the electrical purification body to filter large particles in the air first.
It should be noted that the purification module 10 and the ionizer 20 operate after receiving the high voltage direct current output by the high voltage generator 31, and adsorb dust in the air to purify the air entering the air evolution device. Since dust in the air is adsorbed on the purification module 10, the purification module 10 needs to be detached and cleaned after a certain time of use. If the high voltage generator 31 is in an operating state and outputs high voltage dc power during the process of assembling and disassembling the purification module 10, a user may get an electric shock and there is a safety risk. In addition, during the process of assembling and disassembling the purification module 10, if the ion generator 20 is also in the working state, ions that can be automatically adsorbed on the particulate pollutants in the air are generated. Although the ion generator 20 operates at a low current, which is typically milliampere, the generated ions may still cause the user to feel an electric shock when contacting the human body, which also has a safety hazard.
In order to solve the above problems, the air purification apparatus of the present invention includes a micro switch 32 in the high voltage pack assembly 30, wherein the micro switch 32 is serially connected between the input terminal of the high voltage generator 31 and the dc power VCC. When the purification module 10 is assembled into the air purification device and triggered by the purification module 10, the purification module is closed, so that the high-voltage generator 31 supplies power to the purification module 10 and the ionizer 20 to drive the ionizer 20 to generate free ions which can be automatically adsorbed on particulate pollutants in the air, so that the particulate pollutants are charged; and driving the purification module 10 to generate an electric field sufficient to ionize the gas. After being ionized by the ionizer 20, the particulate pollutants are charged and then move to the electrode plates with different polarities respectively under the action of the electric field force, and are deposited on the electrode plates of the purification module 10, so that the air entering the purification module 10 is purified. The purification module 10 is detached (taken out) from the air purification device and is switched off when being triggered by the purification module 10, so that the high-voltage generator 31 stops supplying power to the purification module 10 and the ion generator 20, and the problem that in the process of detaching the purification module 10, the high-voltage generator 31 is in a working state and outputs high-voltage direct current, so that a user is in electric shock and potential safety hazard exists is solved. The invention is beneficial to improving the safety performance of the air purification device.
It can be understood that, in the above embodiment, the purification module 10 and the ionizer 20 both use the same high voltage generator 31 for power supply, and compared with the case that two independent high voltage generators 31 are used for independent power supply of the purification module 10 and the ionizer 20, the control difficulty of the high voltage pack assembly 30 can be reduced.
