[0038] Referring to Figure 1 and Figure 2The purifier provided by an embodiment of the present application comprises an air inlet, an air outlet and a sterilization port. The purifier sucks in air through the air inlet and purifies the pollutants in the sucked-in air. The purified air is discharged from the purifier through the air outlet, so as to purify the indoor air. Meanwhile, the purifier comprises the sterilization port. The purifier can spray water mist with electric charges through the sterilization port, so as to sterilize the surface of an object through anions or cations in the water mist. Thus, the purifier can continuously suck in polluted air and discharge clean air while spraying water mist to sterilize the surface of an object, so that the purifier can be applied to sterilize the surface of an object while purifying air.

[0039] In order to achieve the above effect, the purifier comprises a purification device. The purification device comprises a dust collecting unit 10 and an ion emitting source 20. The dust collecting unit 10 is used to adsorb dust and moisture in air. The air inlet and the air outlet of the purifier are connected through a purification channel. The dust collecting unit 10 is arranged in the purification channel. The air sucked in by the air inlet of the purifier enters the purification channel and is adsorbed by the dust collecting unit 10. Finally, the purified air is discharged from the air outlet, so as to purify the air through the dust collecting unit.

[0040] It should be noted that the dust collecting unit 10 can adopt a conventional dust collecting mode such as electrostatic dust collecting or centrifugal dust collecting to collect dust and moisture in air. For example, when the centrifugal dust collecting is adopted, the air rotates in the purifier to form a rotating air flow. The air flow carries the dust and moisture in the air to the side wall of the purification channel and deposits the dust and moisture on the dust collecting unit 10 under the action of gravity, so that the dust collecting unit 10 adsorbs the dust and moisture in the air. When the electrostatic dust collecting is adopted, the parallel plate and ion emitting source can be referred to. Details are not described herein.

[0041] The dust collecting unit 10 comprises a dust collecting piece 16 and a discharge tip piece 13. The dust and moisture collected by the dust collecting unit 10 are adsorbed on the dust collecting piece 16. The tip of the discharge tip piece 13 is arranged towards the sterilization port, so that the ion can be emitted towards the sterilization port under the electrification. The ion wind is generated in the movement of the ion towards the sterilization port. The ion wind carrying the ion is sprayed from the sterilization port and finally sprayed on the surface of an object, so as to form ion sterilization on the surface of the object.

[0042] In actual use, the discharge tip piece 13 can be connected to the positive pole or the negative pole of a power supply. The dust collecting piece 16 is connected to the negative pole or the positive pole of the power supply. Thus, a potential difference is generated between the tip of the discharge tip piece 13 and the dust collecting piece 16, so that the corona discharge is formed and the air is electrolyzed to generate a large amount of positive ions and negative ions.

[0043] In other embodiments, the dust collecting member 16 and the discharge tip member 13 can be integrally formed with a metal conductor, and a discharge body, such as the second discharge body 15, having a potential difference with the discharge tip member 13 can be arranged at intervals around the periphery of the discharge tip member 10. The tip of the discharge tip member 13 will generate corona discharge with the discharge body, which can also electrolyze air and generate a large number of positive and negative ions, thereby generating an ion wind.

[0044] Specifically, among the large number of ions emitted by the discharge tip member 13, the ions can be positive ions, negative ions, or both. Regardless of whether they are positive ions or negative ions, they can produce a huge energy release in an instant when they neutralize the positive and negative charges of the air on the surface of the object, thereby causing changes in the structure of bacteria or energy conversion in the surrounding bacteria, resulting in the death of the bacteria and achieving the sterilization effect. Because the number of negative ions is greater than the number of positive ions, the excess negative ions still float in the air, which can achieve the effects of smoke removal, dust removal, odor elimination, and air quality improvement to promote the health care of the human body.

[0045] Referring to Figure 2 and Figure 3 To further improve the sterilization effect on the surface of the object, the dust collecting unit 10 further includes a water accumulation hole 14 that communicates the surface of the dust collecting member 16 and the area where the tip of the discharge tip member 13 is located. As known above, due to the adsorption of water and dust in the air by the dust collecting member 16, a large amount of water will be accumulated on the surface of the dust collecting member 16, and the accumulated water can flow into the tip of the discharge tip member 13 through the water accumulation hole 14.

[0046] The area where the tip of the discharge tip member 13 is located is also the area where the discharge tip member 13 generates ions and generates an ion wind. Therefore, the ions generated by the discharge tip member 13 will be wrapped by the water droplets flowing out of the water accumulation hole 14, forming a state of "water film wrapping ions". The ions combine with the particles in the water droplets to form strong oxidizing substances such as hydroxyl groups in the water droplets. Finally, the water droplets carry strong oxidizing substances and charged ions under the action of the ion wind generated by the discharge tip member 13, and are sprayed on the surface of the object from the sterilization port of the purifier, completing the sterilization and disinfection of the surface of the object.

[0047] The dust collecting unit 10 is used to adsorb dust and moisture in the air, so as to complete the purification of the air. At the same time, the moisture adsorbed on the dust collecting unit 10 will flow into the tip of the discharge tip piece 13 through the water accumulation hole 14. The area where the tip of the discharge tip piece 13 is located is also the area where the discharge tip piece 13 generates ions and generates ion wind. Therefore, the ions generated by the discharge tip piece 13 will be wrapped by the water droplets flowing out of the water accumulation hole, forming a state of "water film wrapping ions". The ions combine with the particles in the water droplets to form strong oxidizing substances such as hydroxyl groups in the water droplets. Finally, under the action of the ion wind, the water droplets carry strong oxidizing substances and charged ions, and are sprayed from the sterilization port of the purifier to the surface of the object, completing the sterilization and disinfection of the surface of the object. Compared with traditional air purifiers or object surface disinfectors, the above-mentioned purification device can be used for air purification and object surface disinfection at the same time, which facilitates the user to simultaneously perform air purification and object disinfection operations.

[0048] In some embodiments of the present application, referring to Figure 3 The water accumulation hole 14 penetrates the tip of the discharge tip 13, so that the water accumulated on the surface of the dust collecting piece 16 can flow directly into the tip of the discharge tip piece 13 through the water accumulation hole 14, and form water droplets on the tip of the discharge tip piece 13, so that the ions generated by the discharge tip piece 13 will be wrapped by the water droplets, forming a state of "water film wrapping ions". In this way, opening the water accumulation hole 14 at the tip of the discharge tip piece 13 can improve the combination effect of water droplets and ions, thereby increasing the content of strong oxidizing substances such as hydroxyl groups formed in the water droplets, and further improving the sterilization and disinfection effect on the surface of the object. It should be noted that in other embodiments, the purification device can also include a flow guide pipe, and the water accumulation hole 14 is arranged on one end of the flow guide pipe, and the other end of the flow guide pipe is communicated with the surface of the dust collecting piece 16, so as to guide the water accumulated on the surface of the dust collecting piece 16 into the tip of the discharge tip.

[0049] In some embodiments, in order to avoid the discharge tip piece 13 emitting ions and the dust collecting piece 16 adsorbing moisture and dust in the air, and to avoid excessive interference between the two, the discharge tip piece 13 is arranged on one side surface of the dust collecting piece 16, and the other side surface of the dust collecting piece 16 is used to adsorb moisture and dust in the air, and the water accumulation hole 14 is communicated with the other side surface of the dust collecting piece 16. In this way, the discharge tip piece 13 emits ions, and the dust and moisture in the air are adsorbed, respectively in the space on the opposite sides of the dust collecting piece 16, and the two are not easy to interfere with each other.

[0050] In other embodiments, the dust collecting piece 16 can also be L-shaped, and the discharge tip piece 13 is arranged on one side of the L-shaped dust collecting piece 16, and the other side of the L-shaped dust collecting piece 16 can be used to adsorb moisture and dust in the air. The shape of the dust collecting piece 16 can be selected according to the actual use, which is not limited here.

[0051] In some embodiments, the dust collecting unit 10 achieves the effect of purifying air by electrostatically adsorbing dust in the air, and the purification device further comprises an electrode plate 40, which is spaced apart from the other side surface of the dust collecting member 16 to form an electric field area 41. In actual use, the electric field area 41 is located in the purification channel between the air inlet and the air outlet. When the air entering the air inlet passes through the electric field area 41, the dust and moisture in the air can be adsorbed by the electrostatic force generated by the electric field area 41, so that the dust and moisture are adsorbed on the dust collecting member 16.

[0052] It should be noted that when the electrostatic force generated by the electric field area 41 adsorbs the dust and moisture in the air, the dust and moisture in the air also need to carry charges of opposite polarity to the dust collecting member 16, so that the dust and moisture can be adsorbed on the dust collecting member 16.

[0053] Therefore, the purification device further comprises an ion emission source 20, which is used to emit ions of opposite polarity to the dust collecting member 16 towards the electric field area 41, so as to collide with the moisture and dust in the air through the ions of opposite polarity to the dust collecting member 16, and make the moisture and dust carry charges of opposite polarity to the dust collecting member 16, thereby being adsorbed by the dust collecting member 16.

[0054] Specifically, the dust collecting member 16 comprises opposite first and second sides 11 and 12, and has a potential of a first polarity. The ion emission source 20 is used to emit ions of a second polarity towards the first side 11, and the second polarity is opposite to the first polarity, i.e. if the first polarity is positive, the second polarity is negative, and if the first polarity is negative, the second polarity is positive.

[0055] The electrode plate 40 is spaced apart from the first side 11 of the dust collecting member 16 and has a potential of the second polarity, i.e. there is a potential difference between the electrode plate 40 and the dust collecting member 16, thereby generating the electric field area 41. When the moisture and dust carrying the second polarity charges pass between the electrode plate 40 and the dust collecting member 16, they will be adsorbed onto the second side 12 of the dust collecting unit 10 under the action of the Coulomb force of the electric field area 41.

[0056] Optionally, the electrode plate 40 and the first side 11 of the dust collecting unit 10 are arranged parallel to each other, so that the electrostatic field formed between the electrode plate 40 and the dust collecting member 16 is more uniform, so that the dust and moisture can be uniformly adsorbed on the dust collecting member 16.

[0057] Thus, the air sucked into the purifier through the air inlet will pass through the electric field region 41 before being discharged from the purifier through the air outlet, and the ions emitted by the ion emission source 20 will collide with the moisture and dust in the air in the electric field region 41, so that the moisture and dust in the air carry a second-polarity electric charge, and the moisture and dust carrying the second-polarity electric charge will move toward the dust collecting member 16 due to the Coulomb force of the electric field region 41, and finally be adsorbed on the first side 11 of the dust collecting member 16. Thus, the air sucked into the purifier will complete the filtration of the moisture and dust in the purifying device, and finally discharge the filtered air from the air outlet, thereby completing the purification of the air.

[0058] Further, the dust collecting member 16 is provided with a discharge tip member 13 on the second side 12, which is used to emit ions with a first polarity toward a direction away from the first side 11, and the ions with the first polarity can form an ion wind on the second side 12 of the dust collecting member 16 in the process of movement, and the disinfection port of the purifier is in communication with the second side 12 of the dust collecting member 16, so that the ions with the first polarity can be carried out from the disinfection port.

[0059] In actual use, compared with the positive cations, the negative anions are more active, and the anions are more prone to charge transfer and oxidation reaction with other substances, especially the disproportionation reaction with water molecules, thereby generating hydrogen peroxide and oxygen. Hydrogen peroxide is a commonly used disinfectant, which can destroy the cell membrane and the normal metabolic process in the cell due to its strong oxidation ability, thereby causing cell death.

[0060] Based on this, in some embodiments of the present application, the first polarity is cathodic, that is, the dust collecting member 16 has a negative potential, and the discharge tip member 13 emits negative anions with negative charges. After the water absorbed on the dust collecting member 16 flows into the discharge tip member 13 to form water droplets through the water accumulation hole 14, the anions are more likely to generate hydrogen peroxide and oxygen with the water droplets, thereby improving the disinfection effect on the surface of the object.

[0061] When the first polarity is cathodic, the second polarity is anodic, that is, the ion emission source 20 emits positive cations with positive charges. When the positive cations pass through the first side 11 of the dust collecting member 16, the positive cations will collide with the moisture and dust in the air, so that the moisture and dust carry positive charges. At the same time, due to the negative potential of the dust collecting member 16, the moisture and dust carrying positive charges will be attracted by the dust collecting member 16 and move toward the dust collecting member 16, and finally be adsorbed on the first side 11 of the dust collecting member 16.

[0062] In some embodiments, in order to enable the ions emitted by the ion emission source 20 to collide with the air in the electric field region 41 between the electrode plate 40 and the dust collecting member 16, the ion emission source 20 comprises a discharge needle 21 and a first discharge body 22, the tip of the discharge needle 21 is directed towards the gap between the electrode plate 40 and has a potential of the second polarity, and the first discharge body 22 is spaced apart from the tip of the discharge needle 21 and has a potential of the first polarity, i.e. there is a potential difference between the first discharge body 22 and the discharge needle 21.

[0063] Due to the difference in potential between the discharge needle 21 and the first discharge body 22, the air between the discharge needle 21 and the first discharge body 22 is ionized and excited, the first discharge body 22 and the discharge needle 21 appear corona discharge, the air is decomposed to form a large number of positive ions with positive charges and a large number of negative ions with negative charges. Since the discharge needle 21 has a second potential, i.e. a positive potential, the tip of the discharge needle 21 attracts the negative ions in the air and expels the positive ions in the air, and after the positive ions are repelled by the discharge needle 21, they diffuse away from the discharge needle 21, i.e. the positive ions move towards the gap between the electrode plate 40 and the integrated plate and collide with the moisture and dust in the air in the gap, so that the dust and moisture are charged positively and are adsorbed by the dust collecting member 16.

[0064] In some embodiments, the first discharge body 22 is arranged around the tip of the discharge needle 21, so that when the first discharge body 22 and the discharge needle 21 appear corona discharge, the air between the first discharge body 22 and the discharge needle 21 is decomposed to form a large number of positive ions and negative ions around the discharge needle 21, and since the discharge needle 21 repels the positive ions, the large number of positive ions around the discharge needle 21 move away from the discharge needle 21 and form a conical trajectory, so that the moving positive ions can cover more space between the electrode plate 40 and the integrated plate, and more moisture and dust in the air in the gap can collide with the positive ions, thereby improving the purification effect of the air.

[0065] It should be noted that in other embodiments, as shown in Figure 4 the first discharge body 22 can also be a needle structure, and the tip of the second discharge body 22 is spaced apart from the tip of the discharge needle 21 in the direction of the discharge needle 21 towards the electric field region 41, when the first discharge body 22 and the discharge needle 21 are both electrified, the tip of the first discharge body 22 and the tip of the discharge needle 21 will also produce corona discharge, so that the air between the first discharge body 22 and the discharge needle 21 is decomposed to form a large number of positive ions with positive charges and a large number of negative ions with negative charges.

[0066] In some embodiments, in order to supply power to the ion emission source 20 and the electrode plate 40, the purification device further comprises a first power supply 31, the second electrode of the first power supply 31 is electrically connected with the electrode plate 40 and the discharge needle 21, and the first electrode of the first power supply 31 is electrically connected with the first discharge body 22. When the discharge needle 21 and the electrode plate 40 have positive potential and the first discharge body 22 has negative potential, the first electrode of the first power supply 31 is the positive electrode and the second electrode is the negative electrode. When the first power supply 31 is powered on, the electrons of the first power supply 31 flow from the negative electrode to the positive electrode, so that the first discharge body 22 is charged with negative potential and the electrode plate 40 and the discharge needle 21 are charged with positive potential. In this way, the electrode plate 40 and the ion emission source 20 are powered by one first power supply 31, so as to save the volume of the purification device and facilitate the portability of the purifier.

[0067] In some embodiments of the present application, in order to enable the discharge tip 13 to emit ions, the purification device further comprises a second discharge body 15, which is arranged in the vicinity of the tip of the discharge tip 13 and is configured to have a potential difference with the discharge tip 13.

[0068] Because of the potential difference between the second discharge body 15 and the discharge tip 13, the air between the second discharge body 15 and the discharge tip 13 is ionized and excited, and the second discharge body 15 and the discharge tip 13 appear corona discharge, and the air is decomposed to form a large number of positive ions with positive charge and a large number of negative ions with negative charge. Taking the example that the dust collecting member 16 has a negative potential, the corona discharge between the second discharge body 15 and the discharge tip 13 causes the discharge tip 13 to have a large number of electrons, so that the discharge tip 13 attracts positive ions in the air and repels negative ions in the air. After the negative ions are repelled by the discharge tip 13, they will diffuse away from the dust collecting member 16, i.e. the discharge tip 13 emits negative ions away from the first side 11, and in the process of diffusion of the negative ions, an ion wind is formed on the first side 11 of the discharge tip 13, which carries the water droplets on the discharge tip 13 and moves together with the negative ions in the ion wind, and the negative ions in the ion wind generate hydrogen peroxide and oxygen with the water droplets, thereby improving the disinfection effect on the surface of the object.

[0069] To improve the coverage area of the ion wind, in some embodiments, the second discharge body 15 is arranged around the tip of the discharge tip piece 13, so that when the second discharge body 15 and the discharge tip piece 13 generate corona discharge, the air between the second discharge body 15 and the discharge tip piece 13 is decomposed to form a large number of positive ions and negative ions around the discharge tip piece 13, and since the discharge tip piece 13 repels negative ions, a large number of negative ions around the discharge tip piece 13 will move away from the discharge tip piece 13 and form a conical trajectory, so that the ion wind formed by the negative ions is also conical. The conical ion wind can carry water droplets to cover a larger area of the object surface, thereby further improving the disinfection effect on the object surface.

[0070] In other embodiments, as shown in Figure 4 The second discharge body 15 can also be a needle structure, and the tip of the second discharge body 15 is arranged away from the tip of the discharge tip piece 13 in the direction away from the dust collecting piece 16. When the second discharge body 15 and the discharge tip piece 13 are both electrified, corona discharge occurs between the tip of the second discharge body 15 and the tip of the discharge tip piece 13, so that the air between the second discharge body 15 and the discharge tip piece 13 is decomposed to form a large number of positive ions with positive charges and a large number of negative ions with negative charges.

[0071] It should be noted that in still another embodiment, referring to Figure 5 The second discharge body 15 can also be arranged around the tip of the discharge tip piece 13, and the first discharge body 22 can be a needle structure. The structures of the second discharge body 15 and the first discharge body 22 can be selected according to actual use requirements, which are not limited herein.

[0072] In some embodiments, the discharge tip piece 13 includes a plurality of discharge tip pieces 13 arranged on the same side of the dust collecting piece 16, i.e., the plurality of discharge tip pieces 13 are arranged on the second side 12 of the dust collecting piece 16. The second discharge body 15 includes a plurality of second discharge bodies 15 corresponding to the plurality of discharge tip pieces 13, so that each discharge body can form corona discharge with the corresponding discharge tip piece 13, and each discharge tip piece 13 can form an ion wind. The plurality of discharge tip pieces 13 cooperate to increase the coverage area of the ion wind, so that the purifier can cover a larger area of the object surface, thereby further improving the disinfection effect on the object surface.

[0073] Alternatively, all the discharge tip pieces 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 tip pieces 13 can be controlled according to the shape of the purification port of the purifier, so that the ion winds formed by all the discharge tip pieces 13 can be normally sprayed from the purification port of the purifier.

[0074] In some embodiments, the purification device further comprises a second power supply 30, a first electrode of the second power supply 30 is electrically connected with one of the second discharge bodies 15, and the plurality of second discharge bodies 15 are connected in series with each other, so that each of the second discharge bodies 15 has the same polarity as the first electrode of the second power supply 30. A second electrode of the second power supply 30 is electrically connected with the dust collecting unit 10.

[0075] Taking the example that the dust collecting member 16 has a negative electric potential and the discharge part is capable of emitting anions with negative charges, the first electrode of the second power supply 30 is positive, the second electrode of the second power supply 30 is negative, and the direction of the current is the movement direction of the positive charges. Therefore, the positive charges of the second power supply 30 flow from the first electrode to the second electrode, and the electrons of the second power supply 30 flow from the second electrode to the first electrode. Since the dust collecting member 16 is connected with the first electrode of the second power supply 30, the electrons of the second power supply 30 flow from the first electrode to the dust collecting member 16, so that the dust collecting member 16 is charged with negative charges, i.e. the dust collecting member 16 has a negative electric potential, thereby enabling the dust collecting member 16 to attract water and dust with positive charges.

[0076] The working process of the purification device of the present application will be described below in combination with the accompanying drawings. Figure 1

[0077] 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 to generate a large number of positive ions, and the positive ions are pushed to move towards the electrode plate 40 and the dust collecting member 16.

[0078] The positive electrode of the second power supply 30 is electrically connected with the second discharge body 15, and the negative electrode of the second power supply 30 is connected with the dust collecting member 16. The dust collecting member 16 and the electrode plate 40 generate an electric field area 41 therebetween. The ions emitted by the discharge needle 21 collide with the water and dust in the air, so that the water and dust in the air are charged with positive charges. The water and dust charged with positive charges 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.

[0079] ​Meanwhile, the water adsorbed on the dust collecting member 16 will flow into the discharge tip member 13 through the water collecting hole 14 under the siphon effect of the discharge tip member 13 and the ion pushing effect, and form water droplets. The discharge tip member 13 and the second discharge body 15 generate corona discharge and form a large amount of ion wind with negative charge. The water droplets will carry strong oxidizing substances and negative ions under the effect of the ion wind, and spray on the surface of the object from the sterilization port of the purifier, thus completing the sterilization and disinfection of the surface of the object. In this way, compared with the traditional air purifier or object surface sterilizer, the above-mentioned purifying device can be used for air purification and object surface disinfection at the same time, which is convenient for the user to simultaneously perform air purification and object disinfection operations.

[0080] The technical features of the above-described embodiments can be combined in any manner. For the sake of brevity, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combinations of the technical features do not contradict each other, they should be considered within the scope of the present disclosure.

[0081] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
