Referring to fig. 1 and 2, the purifier provided by an embodiment of the application comprises an air inlet, an air outlet and a sterilizing port, wherein the purifier sucks air through the air inlet and performs evolutionary treatment on pollutants in the sucked air, and the air after the treatment is discharged out of the evolutionary device through the air outlet so as to achieve the effect of evolutionary treatment on indoor air. Meanwhile, the purifier further comprises a disinfection opening, and the purifier can spray water mist with charges through the disinfection opening so as to disinfect the surface of an object through anions or positive ions in the water mist. Therefore, the purifier can continuously suck in polluted air and discharge clean air when spraying water mist to disinfect the surface of an object, so that the purifier can be applicable to disinfection of the surface of the object while purifying the air.

In order to achieve the above effect, the purifier includes a purifying device including a dust collecting unit 10 and an ion emitting source 20, the dust collecting unit 10 being used to adsorb dust and moisture in the air. The air inlet and the air outlet of the purifier are communicated through the purification channel, the dust collecting unit 10 is arranged in the purification channel, the purifier is filled with air sucked through the air inlet, dust and moisture are adsorbed by the dust collecting unit 10, and finally the evolved air is discharged from the air outlet, so that the effect of purifying the air through the dust collecting unit is achieved.

It should be noted that, the dust collecting unit 10 may collect dust and moisture in air in a conventional dust collecting manner, such as electrostatic dust collection or centrifugal dust collection, for example, when centrifugal dust collection is used, the air rotates in the purifier to form a rotating air flow, and the air flow brings the dust and moisture in the air to the side wall of the purifying channel and is deposited on the dust collecting unit 10 under the action of gravity, so that the dust collecting unit 10 completes the adsorption of the dust and dust in the air. When the dust collecting unit 10 adopts electrostatic dust collection, reference may be made to the following parallel plates and ion emission sources, and details thereof will not be described herein.

The dust collecting unit 10 includes a dust collecting member 16 and a discharge tip member 13, dust and moisture collected by the dust collecting unit 10 are adsorbed on the dust collecting member 16, and a tip portion of the discharge tip member 13 is disposed toward the sterilizing opening so as to emit ions toward the sterilizing opening in a state of being energized, and the ions can generate ion wind in a process of moving toward the sterilizing opening, and the ion wind carries the ions to be sprayed out from the sterilizing opening and finally sprayed on the surface of the object so as to form ion sterilization on the surface of the object.

In actual use, the discharge tip 13 may be connected to the positive or negative electrode of the power supply, and the dust collecting member 16 is connected to the negative or positive electrode of the power supply, so that a potential difference is generated between the tip of the discharge tip 13 and the dust collecting member 16, thereby forming corona discharge, and further electrolyzing air to generate a large amount of cations and anions.

In other embodiments, the dust collecting member 16 and the discharge tip member 13 may be integrally formed by using metal conductors, and a discharge body having a potential difference from the discharge tip member 13, such as a second discharge body 15 described below, is provided at a periphery of the discharge tip member 10, and corona discharge is generated at the tip portion of the discharge tip member 13 with the discharge body, which also electrolyzes air and generates a large amount of cations and anions, thereby generating ion wind.

In particular, the discharge tip 13 emits a large amount of ions, which may be cations, anions or both, which can generate a great energy release at the moment of neutralization of positive and negative charges with air on the surface of the object, thereby causing a change in the structure or energy conversion of bacteria around it, causing the bacteria to die, thus achieving their bactericidal effect. Because the number of negative ions is larger than that of positive ions, redundant negative ions still float in the air, so that the effects of eliminating smoke, removing dust, eliminating peculiar smell and improving the quality of the air can be achieved, and the health care effect of human health is promoted.

In order to further improve the sterilization effect on the surface of the object, referring to fig. 2 and 3, the dust collecting unit 10 further includes a water accumulating hole 14, the water accumulating hole 14 is communicated with the surface of the dust collecting member 16 and the area where the tip of the discharge tip 13 is located, and as the dust collecting member 16 absorbs moisture and dust in the air, more moisture is accumulated on the surface of the dust collecting member 16, and the accumulated moisture can flow into the tip of the discharge tip 13 through the water accumulating hole 14.

The area of the tip of the discharge tip 13 is also the area where the discharge tip 13 generates ions and generates ion wind, so that the ions generated by the discharge tip 13 are wrapped by the water droplets flowing out of the water accumulation holes 14 to form a water film ion wrapping state, the ions are combined with particles in the water droplets, and strong oxidizing substances such as hydroxyl groups are formed in the water droplets. Finally, the water drops carry strong oxidizing substances and charged ions under the action of the ion wind generated by the discharge tip piece 13, and are sprayed on the surface of the object from the sterilizing opening of the purifier, so that the sterilization and disinfection of the surface of the object are completed.

The above purification device, the dust collecting unit 10 is used to adsorb dust and moisture in the air, thereby completing the purification of the air. Meanwhile, the moisture adsorbed on the dust collecting unit 10 flows into the tip of the discharge tip 13 through the water accumulation hole 14, and the area of the tip of the discharge tip 13 is also the area where the discharge tip 13 generates ions and generates ion wind, so that the ions generated by the discharge tip 13 are wrapped by the water droplets flowing out of the water accumulation hole to form a water film wrapping ion state, the ions are combined with particles in the water droplets, and strong oxidizing substances containing hydroxyl groups and the like are formed in the water droplets. Finally, the water drops carry strong oxidizing substances and charged ions under the action of ion wind, and are sprayed on the surface of an object from a sterilizing opening of the purifier to finish sterilization and disinfection of the surface of the object. Compared with the traditional air purifier or object surface sterilizer, the purifying device can be used for purifying air and sterilizing the object surface at the same time, and is convenient for users to perform air purification and object sterilization operation at the same time.

In some embodiments of the present application, referring to fig. 3, the water accumulation hole 14 penetrates through the tip of the discharge tip 13, so that the water accumulated on the surface of the dust collecting member 16 can directly flow into the tip of the discharge tip 13 through the water accumulation hole 14, and form water droplets on the tip of the discharge tip 13, so that the ions generated by the discharge tip 13 are wrapped by the water droplets, and form a "water film wrapping ion" state. Thus, the water accumulation hole 14 is formed at the tip of the discharge tip 13 to improve the combination effect of water drops and ions, so that the content of strong oxidizing substances such as hydroxyl groups in the water drops is improved, and the sterilization effect on the surface of an object is further improved. It should be noted that, in other embodiments, the purifying device may also include a flow guiding tube, where the water collecting hole 14 is disposed at one end of the flow guiding tube, and the other end of the flow guiding tube is connected to the surface of the dust collecting member 16, so that the water collecting on the surface of the dust collecting member 16 is introduced to the tip of the discharge tip through the flow guiding tube.

In some embodiments, in order to prevent the discharge tip 13 from emitting ions and the dust collection member 16 from adsorbing moisture and dust of the air, excessive interference is generated therebetween, the discharge tip 13 is disposed on one side surface of the dust collection member 16, and the other side surface of the dust collection member 16 is used to adsorb moisture and dust of the air, while the water accumulation hole 14 communicates with the other side surface of the dust collection member 16. In this way, the discharge tips 13 emit ions, and dust and moisture of the air are adsorbed in the spaces on the opposite sides of the dust collection member 16, respectively, so that interference is not easily generated therebetween.

In other embodiments, the integrated member 16 may be L-shaped, the discharge tip 13 is disposed on one side of the L-shaped integrated member 16, and the other side of the L-shaped integrated member 16 may be used to adsorb moisture and dust of air, and the shape of the integrated member 16 may be selected according to actual use conditions, which is not limited herein.

In particular, in some embodiments, the dust collecting unit 10 achieves the effect of purifying air by electrostatically adsorbing dust in air, the evolutionary device further includes a pole plate 40, an electric field region 41 is formed between the pole plate 40 and the other side surface of the dust collecting member 16, and in actual use, the electric field region 41 is located in a purifying channel between the air inlet and the air outlet, and when the air entering from the air inlet passes through the electric field region 41, dust and moisture in the air can be adsorbed by electrostatic force generated by the electric field region 41, so that both the moisture and the dust are adsorbed onto the dust collecting member 16.

It should be noted that, when the electrostatic force generated in the electric field area 41 is required to absorb the dust and moisture in the air, the dust and moisture in the air needs to have charges with polarity opposite to that of the dust collecting member 16, so that the dust and moisture can be absorbed to the dust collecting member 16.

For this, the purifying apparatus further includes an ion emission source 20 for emitting ions of opposite polarity to the dust collecting member 16 toward the electric field region 41 to collide with moisture and dust of air by the ions of opposite polarity to the dust collecting member 16 and to charge the moisture and dust with charges of opposite polarity to the dust collecting member 16, thereby being adsorbed by the dust collecting member 16.

Specifically, the dust collecting member 16 includes a first side 11 and a second side 12 opposite to each other, the dust collecting member 16 has a potential of a first polarity, and the ion emitting source 20 is configured to emit ions of a second polarity toward the first side 11, wherein the second polarity is opposite to the first polarity, i.e., the second polarity is cathodic if the first polarity is anodic, and the second polarity is anodic if the first polarity is cathodic.

The plate 40 is spaced from the first side 11 of the dust collection member 16 and has a potential of a second polarity, i.e., a potential difference between the plate 40 and the dust collection member 16, thereby creating an electric field region 41 that is attracted to the second side 12 of the dust collection unit 10 by the coulomb force of the electric field region 41 as moisture and dust charged at the second polarity passes between the plate 40 and the dust collection member 16.

Alternatively, the plate 40 and the first side 11 of the dust collecting unit 10 are disposed parallel to each other so that an electrostatic field formed between the plate 40 and the dust collecting member 16 is more uniform, so that dust and moisture can be uniformly adsorbed on the dust collecting member 16.

In this way, the air sucked by the air inlet of the purifier passes through the electric field region 41 before being discharged from the air outlet, and ions emitted by the ion emission source 20 collide with moisture and dust in the air in the electric field region 41, so that the moisture and dust in the air are charged with the second polarity, and meanwhile, the moisture and dust charged with the second polarity move toward the dust collecting member 16 due to coulomb force of the electric field region 41 and are finally adsorbed on the first side 11 of the dust collecting member 16. Therefore, the air sucked by the purifier can be filtered in the purifying device, and finally the filtered air is discharged from the air outlet to purify the air.

Further, the dust collecting member 16 is provided with a discharge tip member 13 at the second side 12, the discharge tip member 13 is used for emitting ions with a first polarity towards a direction away from the first side 11, the ions with the first polarity can form ion wind at the second side 12 of the dust collecting member 16 during movement, a sterilizing port of the purifier is communicated with the second side 12 of the dust collecting member 16, and the ion wind can carry the ions with the first polarity to be ejected from the sterilizing port.

In practical use, negative anions are more reactive than positive cations, and anions are more prone to charge transfer and oxidation reactions with other substances, particularly disproportionation reactions with water molecules, so as to generate hydrogen peroxide and oxygen, which are common disinfectants due to their strong oxidizing ability, and can destroy cell membranes and normal metabolic processes in cells, thereby causing cell death.

Based on this, in some embodiments of the present application, the first polarity is cathodic, i.e. there is a negative potential from the dust collection member 16, and the discharge tip member 13 of the discharge tip member 13 emits anions with negative charges, so that the anions are more likely to generate hydrogen peroxide and oxygen with the water droplets after the water adsorbed on the dust collection member 16 flows into the discharge tip member 13 through the water accumulation holes 14 to form water droplets, thereby improving the disinfection effect on the surface of the object.

While when the first polarity is cathodic, the second polarity is anodic, i.e., the positive charged cations are emitted from the ion-emitting source 20 and pass through the first side 11 of the dust collecting member 16, the cations collide with the moisture and dust in the air, so that the moisture and dust are positively charged, and meanwhile, since the dust collecting member 16 has a negative potential, the positively charged moisture and dust are attracted by the dust collecting member 16 and move toward the dust collecting member 16 and are finally adsorbed on the first side 11 of the dust collecting member 16.

In some embodiments, in order to enable the ions emitted from the ion emission source 20 to collide with the air in the electric field region 41 between the plate 40 and the dust collection member 16, the ion emission source 20 includes the discharge needles 21 and the first discharge bodies 22, the tips of the discharge needles 21 face the gap between the plate 40, and have the potential of the second polarity, and the first discharge bodies 22 are spaced apart from the tips of the discharge needles 21 and have the potential of the first polarity, i.e., the potential difference between the first discharge bodies 22 and the discharge needles 21.

Because of the difference in potential between the discharge needle 21 and the first discharge body 22, ionization and excitation of air between the discharge needle 21 and the first discharge body 22 occur, corona discharge occurs between the first discharge body 22 and the discharge needle 21, and the air is decomposed to form a large number of positive-charged cations and a large number of negative-charged anions. Since the discharge needle 21 has the second potential, that is, the positive potential, the tip of the discharge needle 21 attracts anions in the air and discharges cations in the air, and the cations diffuse in a direction away from the discharge needle 21 after being repelled by the discharge needle 21, that is, the cations move toward the gap between the plate 40 and the integrated plate and collide with moisture and dust of the air in the gap, so that the dust and moisture are positively charged to be adsorbed by the dust collecting member 16.

In particular, in some embodiments, the first discharge body 22 is disposed around the tip of the discharge needle 21, so that when corona discharge occurs between the first discharge body 22 and the discharge needle 21, air between the first discharge body 22 and the discharge needle 21 is decomposed to form a large amount of cations and anions around the discharge needle 21, and since the discharge needle 21 repels the cations, the large amount of cations around the discharge needle 21 move away from the discharge needle 21 and form a tapered movement track, so that the moving cations can cover more space between the polar plate 40 and the integrated plate, and more moisture and dust in the air in the gap can collide with the cations, thereby improving the evolutionary effect on the air.

It should be noted that, in other embodiments, as shown in fig. 4, the first discharge body 22 may also have a needle structure, and the tips of the second discharge body 22 and the tips of the discharge needles 21 are arranged at intervals in the direction of the discharge needles 21 toward the electric field regions 41, when both the first discharge body 22 and the discharge needles 21 are energized, corona discharge is generated between the tips of the first discharge body 22 and the tips of the discharge needles 21, so that air between the first discharge body 22 and the discharge needles 21 is decomposed to form a plurality of positive-charged cations and a plurality of negative-charged anions.

In particular, in some embodiments, to supply power to the ion emission source 20 and the electrode plate 40, the purification apparatus further includes a first power source 31, a second electrode of the first power source 31 is electrically connected to the electrode plate 40 and the discharge needle 21, and a first electrode of the first power source 31 is electrically connected to the first discharge body 22. When the discharge needle 21 and the electrode plate 40 have a positive potential and the first discharge body 22 has a negative potential, the first electrode of the first power source 31 is a positive electrode, and the second electrode is a negative electrode, and when the first power source 31 is energized, electrons of the first power source 31 flow from the negative electrode of the first power source 31 to the positive electrode, so that the first discharge body 22 is brought to the negative potential and the electrode plate 40 and the discharge needle 21 are brought to the positive potential. In this way, the polar plate 40 and the ion emission source 20 are powered by a first power source 31, so as to save the volume of the purifying device and facilitate the portability of the purifier.

In some embodiments of the application, in order to enable the discharge tip 13 to emit ions, the evolution device further comprises a second discharge body 15, the second discharge body 14 being arranged spaced apart from the tip of the discharge tip 13 and configured to enable a potential difference with the discharge tip 13.

Due to the potential difference between the second discharge body 14 and the discharge tip 13, the air is ionized and excited between the second discharge body 15 and the discharge tip 13, a corona discharge occurs between the second discharge body 15 and the discharge tip 13, and the air breaks down to form a number of positively charged cations and a number of negatively charged anions. By taking the dust collection piece 16 as an example with a negative potential, the second discharge body 15 and the discharge tip piece 13 generate corona discharge, so that the discharge tip piece 13 carries a large amount of electrons, and therefore, the discharge tip piece 13 attracts cations in the air and repels anions in the air, after the anions are repelled by the discharge tip piece 13, the anions are diffused in a direction away from the dust collection piece 16, namely, the discharge tip piece 13 emits anions in a direction away from the first side 11, and in the process of diffusing the anions, ion wind is formed on the first side 11 of the discharge tip piece 13, the ion wind can carry water drops on the discharge tip piece 13 to move together, and the anions in the ion wind can generate hydrogen peroxide and oxygen with the water drops, so that the disinfection effect on the surface of an object is improved.

In particular, in some embodiments, in order to increase the coverage area of the ion wind, the second discharge body 15 is disposed around the tip of the discharge tip 13, so that when corona discharge occurs between the second discharge body 15 and the discharge tip 13, air between the second discharge body 15 and the discharge tip 13 is decomposed to form a large amount of cations and anions around the discharge tip 13, and since the discharge tip 13 repels anions, a large amount of anions around the discharge tip 13 move in a direction away from the discharge tip 13 and form a tapered movement trace so that the ion wind formed by the anions is also tapered, and the ion wind thus tapered can carry a larger area of the surface of the water droplet covering the object surface, thereby further improving the disinfection effect on the object surface.

In other embodiments, as shown in fig. 4, the second discharge body 15 may also be in a needle structure, and the tips of the second discharge body 15 and the tips of the discharge tips 13 are arranged at intervals in a direction of the discharge tips 13 away from the dust collecting member 16, when both the second discharge body 15 and the discharge tips 13 are energized, corona discharge is generated between the tips of the second discharge body 15 and the tips of the discharge tips 13, so that air between the second discharge body 15 and the discharge tips 13 is decomposed to form a plurality of positive charged cations and a plurality of negative charged anions.

It should be noted that, in still another embodiment, referring to fig. 5, the second discharge body 15 may be disposed around the tip of the discharge tip 13, and the first discharge body 22 is in a needle structure, and the structures of the second discharge body 15 and the first discharge body 22 may be selected according to actual use requirements, which is not limited herein.

In particular, in some embodiments, the discharge tips 13 comprise a plurality of discharge tips 13 that are spaced apart from each other on the same side of the dust collection member 16, i.e. the plurality of discharge tips 13 are disposed on the second side 12 of the dust collection member 16. The second discharge body 15 includes a plurality of discharge tips 13 in one-to-one correspondence, so that each discharge body can form corona discharge with the corresponding discharge tip 13, and each discharge tip 13 can form ion wind, and the plurality of discharge tips 13 are mutually matched, so that the coverage area of the ion wind is increased, thereby enabling the purifier to cover a larger area of the surface of the object, and further improving the disinfection effect on the surface of the object.

Alternatively, all the discharge tips 13 are arranged in a matrix on the second side 12 of the dust collecting unit 10, and in other embodiments, the arrangement of the discharge tips 13 can be controlled according to the shape of the purge port of the purifier, so that the ion wind formed by all the discharge tips 13 can be ejected from the purge port of the purifier normally.

In some embodiments, the purifying apparatus further includes a second power source 30, the first electrode of the second power source 30 is electrically connected to one of the second discharge bodies 15, and the plurality of second discharge bodies 15 are connected in series with each other such that each second discharge body 15 has the same polarity as the first electrode of the second power source 30. The second electrode of the second power supply 30 is electrically connected to the dust collection unit 10.

Taking the case that the dust collecting member 16 has a negative potential and the discharge portion is allowed to emit anions having negative charges as an example, the first electrode of the second power source 30 is positive, the second electrode of the second power source 30 is negative, and the direction of the current is the movement direction of the positive charges, so that the positive charges of the second power source 30 flow from the first electrode to the second electrode, while the electrons of the second power source 30 flow from the second electrode to the first electrode, and the dust collecting member 16 is connected to the first electrode of the second power source 30, so that the electrons of the second power source 30 flow from the first electrode to the dust collecting member 16 to make the dust collecting member 16 negatively charged, i.e., to make the dust collecting member 16 have a negative potential, so that the dust collecting member 16 can attract moisture and dust having positive charges.

The operation of the purification device of the present application will be described with reference to fig. 1:

the positive electrode of the first power supply 32 is electrically connected with the discharge needle 21, and the negative electrode of the first power supply 32 is electrically connected with the electrode plate 40 and the first discharge body 22, so that the air between the discharge needle 21 and the first discharge body 22 is ionized, a large amount of cations are generated, and the cations are pushed to move between the electrode plate 40 and the dust collecting member 16.

The positive electrode of the second power supply 30 is electrically connected with the second discharging body 15, the negative electrode of the second power supply 30 is connected with the dust collecting member 16, an electric field region 41 is generated between the dust collecting member 16 and the polar plate 40, ions emitted by the discharging needle 21 collide with moisture and dust in the air, so that the moisture and dust in the air carry positive charges, and the moisture and dust carrying positive charges can move towards the dust collecting member 16 with negative charges and are adsorbed on the first side 11 of the dust collecting unit 10, thereby completing the purification of the air.

Meanwhile, the water adsorbed on the dust collecting piece 16 can flow into the discharge tip piece 13 through the water accumulation hole 14 to form water drops under the siphon action of the discharge tip piece 13 and the ion pushing action, corona discharge is generated between the discharge tip piece 13 and the second discharge body 15, a large amount of negative ion wind is formed, the water drops carry strong oxidation substances and negative ions under the action of the ion wind, and the water drops are sprayed on the surface of an object from a sterilizing opening of the purifier to sterilize and disinfect the surface of the object. Therefore, compared with the traditional air purifier or object surface sterilizer, the purifying device can be used for purifying air and sterilizing the object surface at the same time, and is convenient for users to perform air purification and object sterilization operation at the same time.
