Description

Technical Field

[0001] The present invention relates to the technical field of filters, and particularly to an air purification device, an air treatment core body, and a positive and negative ion generating device thereof. Background Art

[0002] The electrostatic dust removal process mainly adsorbs charged particles in the air through a parallel electric field to achieve the effect of dust removal. However, this technology is only effective for charged particles. Since there are few charged particles in the air, the purification efficiency of the single parallel electric field is not high. Therefore, in the existing electrostatic dust removal process, a charging device is also arranged upstream of the parallel electric field to charge the particles in the air, thereby improving the efficiency of electrostatic dust removal.

[0003] However, the existing charging devices often have relatively single functions and are prone to generating a high concentration of ozone, making it difficult to meet the increasing functional requirements. Summary of the Invention

[0004] The purpose of the present invention is to provide an air purification device, an air treatment core body, and a positive and negative ion generating device. Among them, in addition to charging the particulate matter in the air, the positive and negative ion generating device can also have functions such as sterilization and disinfection, decomposition of volatile organic compounds, and reduction of ozone concentration, with more diverse functions.

[0005] To solve the above technical problems, the present invention provides a positive and negative ion generating device, which includes a first member and a second member arranged opposite to each other. The first member is provided with a positive electrode emitter, and the positive electrode emitter is used for electrically connecting to the positive electrode of a power supply. The second member is provided with a negative electrode emitter, and the negative electrode emitter is used for electrically connecting to the negative electrode of the power supply.

[0006] Different from the background art, the positive and negative ion generating device provided by the present invention is simultaneously configured with a positive electrode emitter and a negative electrode emitter. When in use, the positive electrode emitter can emit positive ions, and the negative electrode emitter can emit negative ions. When the particulate matter or microorganisms in the air pass through or approach one of the positive ion emission area and the negative ion emission area, they can carry the corresponding charge, and then when passing through or approaching the other of the positive ion emission area and the negative ion emission area, they can neutralize the positive and negative charges. The process of neutralizing the positive and negative charges can release a huge amount of energy, thereby killing surrounding bacteria and viruses, and being able to efficiently decompose TVOCs such as formaldehyde, benzene series, and ammonia. While charging the particulate matter in the air, the functions of sterilization and disinfection and decomposition of total volatile organic compounds are realized, thus achieving the technical purpose of diversifying the functions of the charging device.

[0007] In addition, for a general charging device that only provides a single type of charged ion (positive ion or negative ion), ozone is likely to be generated near the emitter. Especially when the external voltage is too high, the ozone concentration will seriously exceed the standard. After adopting the above-mentioned positive and negative ion generating device, since a large amount of energy is released during the neutralization process of positive and negative charges, this part of the energy can drive the decomposition of ozone to form oxygen, thereby greatly reducing the ozone concentration and ensuring the safety of use.

[0008] Optionally, the first member is provided with a first pore associated with the negative emitter; and / or, the second member is provided with a second pore associated with the positive emitter.

[0009] Optionally, the first pore and / or the second pore is a circular hole or a special-shaped hole.

[0010] Optionally, the negative emitter corresponds to the first pore one by one, and the negative emitter is located at the center of the corresponding first pore; and / or, the positive emitter corresponds to the second pore one by one, and the positive emitter is located at the center of the corresponding second pore.

[0011] Optionally, the first member and / or the second member is provided with a substrate, and the positive emitter and the first pore are both arranged on the substrate of the first member, and the negative emitter and the second pore are both arranged on the substrate of the second member.

[0012] Optionally, the first member and / or the second member includes a plurality of spaced-apart base strips, the positive emitter is arranged on the base strip of the first member, the first pore is formed between two adjacent base strips of the first member, the negative emitter is arranged on the base strip of the second member, and the second pore is formed between two adjacent base strips of the second member.

[0013] Optionally, the materials of the first member and the second member are conductive materials; or, a conductive material-made edging is provided at the pore walls of the first pore and the second pore.

[0014] Optionally, it further includes an outer frame, and the first member and the second member are both installed in the outer frame.

[0015] Optionally, the outer frame includes a split upper beam, a lower beam and side beams.

[0016] Optionally, a high-voltage power supply installation cavity is integrated in the outer frame for installing a high-voltage power supply.

[0017] The present invention also provides an air treatment core body, which includes a charging device and a filter. The charging device is the above-mentioned positive and negative ion generating device, and the positive and negative ion generating device is located upstream of the filter.

[0018] Since the above-mentioned positive and negative ion generating device already has the above technical effects, then the air treatment core body having this positive and negative ion generating device should also have similar technical effects, so it will not be elaborated here.

[0019] Optionally, the filter is one of an electrostatic filter, a fiber medium filter, an electret filter, and a triboelectric nanofilter.

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] The terms "first", "second", etc. described herein are only for facilitating the description of two or more structures or components with the same or similar structures, and do not represent a special limitation on the order and / or importance.

[0033] Embodiment 1

[0034] Please refer to Figure 1-4 , Figure 1 which is a schematic structural diagram of a specific embodiment of the first member and the second member of the positive and negative ion generating device provided by the present invention, Figure 2 is Figure 1 the left view of Figure 3 which is a schematic structural diagram of another specific embodiment of the first member and the second member of the positive and negative ion generating device provided by the present invention, Figure 4 is Figure 2 the left view of Figure 5 which is a schematic structural diagram of the positive and negative ion generating device provided by the present invention, Figure 6 is Figure 5 the partial view of

[0035] As Figure 1-4 shown, the present invention provides a positive and negative ion generating device, including a first member 1 and a second member 2 arranged oppositely. The first member 1 is provided with a positive electrode emitter 11, and the positive electrode emitter 11 is used for electrically connecting to the positive electrode of the power supply. The second member 2 is provided with a negative electrode emitter 21, and the negative electrode emitter 21 is used for electrically connecting to the negative electrode of the power supply.

[0036] Different from the background art, the positive and negative ion generating device provided by the present invention is simultaneously provided with a positive electrode emitter 11 and a negative electrode emitter 21. When in use, the positive electrode emitter 11 can emit positive ions, and the negative electrode emitter 21 can emit negative ions. When the particulate matter or microorganisms in the air pass through or approach one of the positive ion emission region and the negative ion emission region, they can carry the corresponding charges, and then when passing through or approaching the other of the positive ion emission region and the negative ion emission region, they can neutralize the positive and negative charges. The process of neutralizing the positive and negative charges can release huge energy, thereby killing surrounding bacteria and viruses, and being able to efficiently decompose TVOC (Total Volatile Organic Compounds, namely total volatile organic compounds) such as formaldehyde, benzene series substances, and ammonia, so as to realize the functions of sterilization, disinfection, and decomposition of total volatile organic compounds while charging the particulate matter in the air, thereby achieving the technical purpose of diversifying the functions of the charging device.

[0037] In addition, for general charging devices that only provide single-charge ions (positive ions or negative ions), ozone is easily generated near the emitter, especially when the external voltage is too high, the ozone concentration will seriously exceed the standard. After adopting the above-mentioned positive and negative ion generating device, since the neutralization process of positive and negative charges releases a large amount of energy, this part of energy can drive the decomposition of ozone to form oxygen, thereby greatly reducing the concentration of ozone and ensuring safety in use.

[0038] As for the electrical properties of the charges ultimately carried by the particles in the air, they can be controlled by adjusting the amount of electricity released by the positive emitter 11 and the negative emitter 21 .

[0039] It should be noted that the embodiment of the present invention does not limit the number of the positive emitters 11 and the negative emitters 21. In practical applications, those skilled in the art can design according to actual needs as long as the above-mentioned technical effects can be guaranteed. Generally speaking, the number of the positive emitters 11 arranged on the first component 1 and the number of the negative emitters 21 arranged on the second component 2 can be multiple, so as to expand the coverage of the positive ion emission area and the negative ion emission area as much as possible, thereby ensuring the above-mentioned technical effects of sterilization, decomposition of total volatile organic compounds, decomposition of ozone and charging of particulate matter to a large extent.

[0040] In addition, the embodiments of the present invention do not limit the structures of the positive emitter 11 and the negative emitter 21 , and the details may refer to the prior art.

[0041] Further, the first component 1 may be provided with a first aperture 121 associated with the negative emitter 21 ; and / or the second component 2 may be provided with a second aperture 221 associated with the positive emitter 11 .

[0042] The first pores 121 and the second pores 221 can be used for ventilation to ensure that air can smoothly pass through the first component 1 and the second component 2. Of course, the first component 1 and the second component 2 may also present a non-90 degree angle with the wind direction, in which case air can directly enter from between the first component 1 and the second component 2, that is, the first pores 121 and the second pores 221 may not exist.

[0043] In addition, the first pore 121 and the second pore 221 can also cooperate with the corresponding emitter to play the role of uniform electric field. At this time, at least the hole wall of the first pore 121 and the second pore 221 should be made of conductive material, and the conductive material here can be metal material, conductive plastic, etc. In specific practice, the first component 1 and the second component 2 can be made of conductive material as a whole; or, it is also possible to set a rim made of conductive material only at the hole wall of the corresponding pore, and the rim can specifically be a ring-shaped conductive strip formed by printing through a printing process. In addition, a ring body made of conductive material can also be pre-embedded at the hole wall of the corresponding pore, and then the ring body is formed integrally with the corresponding component, or the above-mentioned ring body can be welded at the hole wall of the corresponding pore through a welding process.

[0044] Specifically in the embodiment of the present invention, it is preferred to adopt a solution in which the first component 1 and the second component 2 are made of conductive materials as a whole to simplify the structure of the first component 1 and the second component 2; and for a solution in which the number of positive emitters 11 and negative emitters 21 is multiple, adopting this structure, it is not necessary to supply power to each emitter separately, but it is possible to directly supply power to the first component 1 and the second component 2 as a whole, which is also conducive to simplifying the circuit structure.

[0045] For the scheme of providing conductive material only at the pore walls of the corresponding pores, in specific practice, each positive emitter 11 and each negative emitter 21 can be powered separately, or conductive strips can be provided on the corresponding components through a printing process, etc., so as to electrically connect each positive emitter 11 or each negative emitter 21 together through the conductive strips. In this way, only one conductive strip or one emitter needs to be powered to meet the power supply requirement of all emitters of a certain component, and the circuit structure can also be relatively simple.

[0046] The first pore 121 and / or the second pore 221 mentioned above can be circular holes or irregular holes, where irregular holes refer to non-circular holes, such as triangular holes, quadrilateral holes or other holes with complex shapes. Preferably, the embodiment of the present invention can use circular holes as the first pore 121 and the second pore 221, so that the electric field formed by the corresponding emitter can be better matched to achieve a better technical effect of uniform electric field.

[0047] Further, the negative emitter 21 and the first pore 121 may correspond one to one, and the negative emitter 21 may be located at the center of the corresponding first pore 121; and / or, the positive emitter 11 and the second pore 221 may correspond one to one, and the positive emitter 11 may be located at the center of the corresponding second pore 221. In this way, each emitter has a pore corresponding to it, and each emitter is located at the center of the corresponding pore, which can better match the electric field generated by the emitter and can enhance the technical effect of the uniform electric field to a greater extent.

[0048] The above-mentioned solutions mainly describe the emitters and pores of the first component 1 and the second component 2. In the following embodiments of the present invention, the main structures of the first component 1 and the second component 2 will also be described.

[0049] In one solution, as Figure 1 、 Figure 2 shown, the first component 1 and / or the second component 2 may include a substrate. That is to say, the first component 1 and / or the second component 2 as a whole may be in a plate shape. For the convenience of description, the substrate of the first component 1 may be called the first substrate 12, and the substrate of the second component 2 may be called the second substrate 22. Then, the aforementioned positive emitter 11 and the first pore 121 may be provided on the first substrate 12, and the aforementioned negative emitter 21 and the second pore 221 may be provided on the second substrate 22.

[0050] Combined with the foregoing content, the first substrate 12 and the second substrate 22 may be entirely made of a conductive material, or the first substrate 12 and the second substrate 22 may only be provided with a conductive material on the pore walls corresponding to the pores.

[0051] In another solution, as Figure 3 、 Figure 4 shown, the first component 1 and / or the second component 2 may include a number of spaced-apart base strips 23. The positive emitter 11 may be provided on the base strip 23 of the first component 1, the first pore 121 may be formed between two adjacent base strips 23 of the first component 1, the negative emitter 21 may be provided on the base strip 23 of the second component 2, and the second pore 221 may be formed between two adjacent base strips 23 of the second component 2.

[0052] Since the pores formed between two adjacent base strips 23 may be relatively large, for this solution, there may also be a situation where one pore corresponds to multiple emitters. Combining Figure 4 , taking the solution where the second component 2 includes a number of base strips 23 as an example, the second pore 221 may be a quasi-rectangular hole formed between two adjacent base strips 23. At this time, the second pore 221 may correspond to multiple positive emitters 11.

[0053] Furthermore, as Figure 5 、 Figure 6 shown, the positive and negative ion generating device provided by the present invention may further include an outer frame 3. The aforementioned first component 1 and second component 2 may both be installed in the outer frame 3. The specific installation structure is not limited herein, as long as the reliable fixation of the first component 1 and the second component 2 can be ensured.

[0054] The outer frame 3 can be of an integral structure or a split structure. In the embodiment of the present invention, a split structure is preferably adopted. At this time, the outer frame 3 can include a split upper beam 31, a lower beam 32 and side beams 33. In this way, the dimensions of each beam member can be adjusted as needed during use to better meet the installation requirements of different models of equipment.

[0055] A high-voltage power supply installation cavity 321 can also be integrated within the outer frame 3, and the high-voltage power supply can be installed in this installation cavity. In this way, the outside only needs to supply low-voltage electricity to the positive and negative ion generating device provided by the present invention through the low-voltage contact piece 322, which is more conducive to ensuring safety. In the solution of the attached drawings, the high-voltage power supply installation cavity 321 can be arranged in the lower beam 32. In addition to this, it can also be arranged in other beam members of the outer frame 3.

[0056] Taking Figure 1 、 Figure 2 the embodiment shown as an example, the present invention also conducts experimental tests on it. The specific test conditions are as follows: The above-mentioned positive and negative ion generating device is joined to the ventilation surface of the electrostatic dust collection module, and the periphery of the joint surface is ensured to be sealed. After connecting the power supply, the device to be tested is obtained after the combination is completed; the above-mentioned combined device to be tested is tested in a 30m 3 test chamber according to the experimental method of GB / T 18801-2015, and the PM2.5 purification efficiency, ozone concentration, and formaldehyde purification efficiency are respectively compared and tested.

The positive and negative ion generating device provided by the present invention and the conventional single-ion particulate charging module are both externally connected to the same high voltage, and comparative tests are carried out at different high voltages.

Among them, the charging device is the positive and negative ion generating device involved in each embodiment in Embodiment 1, and the positive and negative ion generating device is located upstream of the filter.

[0068] Since the positive and negative ion generating device in Embodiment 1 already has the above technical effects, then the air treatment core body equipped with this positive and negative ion generating device should also have similar technical effects, so it will not be elaborated here.

[0069] Specifically, the above-mentioned filter is one of an electrostatic filter, a fiber medium filter, an electret filter, and a triboelectric nanometer filter. The specific structures of these filters can refer to the prior art and will not be elaborated here.

[0073] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
