[0060] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0061] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0062] The following is a purification component 100 according to an embodiment of the first aspect of the utility model with reference to the drawings.

[0063] According to the purification component 100 of the embodiment of the utility model, Figure 1 As shown, it includes a power grid component 1, such as Figure 2 As shown, the charging network component 1 includes: a first electrode 11 and a second electrode 12, the first electrodes 11 are two and are arranged at intervals along the first direction X, the second electrode 12 is arranged between the two first electrodes 11, and the second electrode 12 includes an integrated double-headed discharge member 120, and the double-headed discharge member 120 protrudes with a tip portion 121 toward each first electrode 11, and the end of the tip portion 121 close to the first electrode 11 is sharp to form a discharge tip 1211.

[0064] The single double-headed discharge member 120 is an integrated part, for example, an integrally formed part, or two parts fixedly connected to form an inseparable integral structure. The single double-headed discharge member 120 may have only one protruding tip portion 121 or multiple protruding tip portions 121 on the side facing one of the first electrodes 11, and the single double-headed discharge member 120 may have only one protruding tip portion 121 or multiple protruding tip portions 121 on the side facing the other first electrode 11.

[0065] The number of double-ended discharge components 120 included in the second electrode 12 is not limited, and may be one or more. When the second electrode 12 includes multiple double-ended discharge components 120, the structures of each double-ended discharge component 120 may be the same, or at least two double-ended discharge components 120 may have different structures.

[0066] The charging network component 1 includes a first electrode 11 and a second electrode 12. The discharge tip 1211 of the second electrode 12 and the first electrode 11 form a discharge module. After power is turned on, the discharge tip 1211 of the second electrode 12 releases negative ions. When particles in the air pass through, they will be adsorbed by the negative ions and thus carry a negative charge. The charged particles are easily adsorbed onto the filter element, thereby improving the quality of air flowing through the charging network component 1.

[0067] Exemplarily, an electrostatic net component 2 is arranged downstream of the charging network component 1. After the airflow passes through the charging network component 1, the particles in the airflow are adsorbed by negative ions and thus carry a negative charge. The charged particles will be adsorbed on the electrostatic net component 2 after passing through the electrostatic net component 2. The electrostatic net component 2 filters and purifies the airflow, thereby reducing the dust particles in the airflow, improving the air quality, and realizing the air purification function.

[0068] There are two first electrodes 11, one of which is disposed near one end of the charging network component 1 in the first direction X, and the other first electrode 11 is disposed near the other end of the charging network component 1 in the first direction X, and the two first electrodes 11 are disposed at intervals along the first direction X. The double-headed discharge member 120 has a tip portion 121 protruding toward each first electrode 11, that is, the double-headed discharge member 120 has a discharge tip 1211 formed toward each first electrode 11, and the discharge tips 1211 in different directions are matched with the two first electrodes 11 respectively.

[0069] The first electrode 11 and the second electrode 12 disposed near one end of the charging network component 1 in the first direction X form a group of discharge modules with their matching discharge tips 1211, and the first electrode 11 and the second electrode 12 disposed near the other end of the charging network component 1 in the first direction X form another group of discharge modules with their matching discharge tips 1211. When particulate matter in the air passes through the charging network component 1, the negative ions released by the two groups of discharge modules can be adsorbed twice, which can increase the probability of particulate matter in the airflow being adsorbed by negative ions and carrying negative ions, so that the particulate matter can adsorb more negative ions per unit time, and then when the charged particulate matter passes through the filter element, the adsorption efficiency is higher, thereby improving the purification and dust removal effect.

[0070] By setting the double-headed discharge member 120 as an integrated member, the second electrode 12 respectively protrudes with a tip portion 121 to cooperate with the first electrodes 11 on both sides. Compared with setting a second electrode corresponding to each first electrode 11, the gap between the two discharge modules can be omitted, saving space, and the number of parts included in the charging network component 1 can be reduced, which is conducive to the assembly of the second electrode 12, thereby improving the assembly efficiency of the charging network component 1 and reducing the production cost.

[0071] According to the purification component 100 of the embodiment of the utility model, since the second electrode 12 includes an integrated double-headed discharge member 120, the double-headed discharge member 120 has discharge tips 1211 facing the first electrodes 11 on both sides, so that the second electrode 12 can simultaneously cooperate with the first electrodes 11 on both sides to form a discharge module, and the discharge tips 1211 in each discharge module can release negative ions respectively. When the airflow flows through the charging network component 1, the particles in the airflow will be adsorbed by the negative ions and thus carry a negative charge. Since the airflow flows through the two discharge modules successively, the probability of the particles in the airflow being adsorbed by the negative ions and carrying a negative charge can be increased, and the number of particles in the airflow that are adsorbed by the negative ions and carry a negative charge can be increased. When the airflow flows through the downstream electrostatic network component 2, more charged particles can be adsorbed by the positive electrode of the electrostatic network component 2, thereby improving the purification and dust removal effect. In addition, since the double-head discharge component 120 is an integrated component, the overall structure of the charging network component 1 is more compact, the gap between the two discharge modules is eliminated, and space is saved. Moreover, the number of parts included in the charging network component 1 can be reduced, thereby improving the assembly efficiency of the charging network component 1 and reducing the production cost.

[0072] In some embodiments of the present invention, Figure 3 As shown, the second electrode 12 includes an electrode needle 12a, that is, at least one double-headed discharge member 120 is an electrode needle 12a, the axial direction of the electrode needle 12a is the first direction X, and the axial ends of the electrode needle 12a respectively have a tip portion 121, the tip portion 121 is conical and the cross-sectional area gradually decreases toward the first electrode 11.

[0073] The electrode needle 12 a has a tip portion 121 at both axial ends thereof. The cross-sectional area of ​​the tip portion 121 gradually decreases toward the first electrode 11 to form a discharge tip 1211 .

[0074] One electrode needle 12a is correspondingly provided with two pointed ends 121, and the two pointed ends 121 cooperate with the two first electrodes 11 to form two groups of discharge modules. When the airflow flows through the charging network component 1, the negative ions released by the two groups of discharge modules can be adsorbed twice, which can increase the probability of particulate matter in the airflow being adsorbed by negative ions and carrying negative ions.

[0075] By providing the electrode needle 12a, the volume of the electrode needle 12a is relatively small, which can reduce the airflow resistance, facilitate the airflow to pass through the charging network component 1, and thus improve the purification efficiency of the charging network component 1 for the airflow.

[0076] It is worth noting that one electrode needle 12a can be provided, or multiple electrode needles 12a can be provided, and the multiple electrode needles 12a cooperate with the two first electrodes 11 to increase the concentration of negative ions. Alternatively, the second electrode 12 can also include the electrode needle 12a and other discharge structures with a pointed end 121, which can be selected according to actual needs.

[0077] In some embodiments of the present invention, Figure 3 As shown, the electrode needle 12a further includes a cylindrical portion 12a1, and two tip portions 121 are connected to two axial ends of the cylindrical portion 12a1.

[0078] When the size of the tip portion 121 is fixed, which includes the height and the diameter, the distance between the tip portion 121 and the first electrode 11 can be adjusted by adjusting the axial length of the cylindrical portion 12a1 to meet different usage requirements.

[0079] In some embodiments of the present invention, Figure 4 As shown, the second electrode 12 includes an electrode strip 12b, that is, at least one double-headed discharge member 120 is an electrode strip 12b, the width direction of the electrode strip 12b is the first direction X, and both sides of the electrode strip 12b in the width direction respectively protrude with a tip portion 121, the tip portion 121 is a triangle and forms a sharp angle toward the direction of the first electrode 11.

[0080] The electrode strip 12b extends in a direction perpendicular to the first direction X. The width direction of the electrode strip 12b is the first direction X. The electrode strip 12b has protruding tips 121 on both sides facing the first direction X. The tip 121 is triangular, and the sharp corners form discharge tips 1211.

[0081] In some embodiments of the present invention, Figure 4 As shown, each side of the electrode strip 12b in the width direction is provided with a plurality of tip portions 121 arranged at intervals along the length direction of the electrode strip 12b, and the tip portions 121 on both sides in the width direction of the electrode strip 12b are arranged one by one; or, as shown Figure 5 As shown, the tip portions 121 on both sides of the electrode strip 12b in the width direction are staggered along the length direction of the electrode strip 12b.

[0082] Both sides of the electrode strip 12b in the width direction are provided with multiple spaced tip portions 121. By providing one electrode strip 12b, multiple discharge tips 1211 can be provided to increase the concentration of negative ions in the charging network component 1, and further increase the probability of particles in the airflow being adsorbed by negative ions and carrying negative ions.

[0083] By providing the electrode strip 12 b , a plurality of tip portions 121 can be formed on both sides of one electrode strip 12 b , thereby saving installation steps and improving assembly efficiency.

[0084] The tip portions 121 on both sides of the electrode strip 12b in the width direction are arranged one by one, and the electrode strip 12b is constructed as a symmetrical structure along the length direction, which can avoid the electrode strip 12b from being installed upside down or incorrectly, thereby improving assembly efficiency and finished product qualification rate.

[0085] The tip portions 121 on both sides of the electrode strip 12b in the width direction are staggered along the length direction of the electrode strip 12b. In the airflow direction, the gap between the tip portions 121 located upstream is arranged opposite to the tip portions 121 located downstream. Similarly, the gap between the tip portions 121 located downstream is arranged opposite to the tip portions 121 located upstream. Even if the particles in the airflow escape the adsorption of negative ions at the tip portions 121 located upstream, they will be adsorbed by the negative ions at the tip portions 121 located downstream, which can increase the probability of particles in the airflow being adsorbed by negative ions and carrying negative ions, and improve the situation where negative ions are not adsorbed to particles due to excessively high air flow rate.

[0086] It is worth noting that the charging network component 1 can be provided with one electrode strip 12b or multiple electrode strips 12b, and the multiple electrode strips 12b can further increase the number of discharge tips 1211 to increase the concentration of negative ions in the charging network component 1; alternatively, the second electrode 12 can also include electrode strips 12b and other discharge structures with tip portions 121, which can be selected according to actual needs.

[0087] In some embodiments of the present invention, Figure 6 As shown, the first electrode 11 is in the form of a perforated plate and has a plurality of hollow holes 111. The thickness direction of the first electrode 11 is the first direction X. The two first electrodes 11 are arranged in parallel. Figure 7 As shown, the second electrode 12 is provided with a tip portion 121 at the center of each hollow hole 111 .

[0088] The first electrode 11 is in the form of an orifice plate and has a plurality of hollow holes 111. A tip portion 121 is provided at the center of each hollow hole 111. The discharge tip 1211 cooperates with the edge of the hollow hole 111, and the discharge tip 1211 releases negative ions. By configuring the first electrode 11 to be in the form of an orifice plate with a plurality of hollow holes 111, one first electrode 11 can cooperate with a pair of tip portions 121, which can reduce the difficulty of arrangement and is conducive to increasing the concentration of negative ions in the charging network component 1.

[0089] The first electrode 11 is in the form of a perforated plate, and the hollow holes 111 on the first electrode 11 can be arranged in an array to present a four-grid, six-grid, nine-grid, and other designs.

[0090] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the cross-sectional area of ​​the tip portion 121 gradually decreases toward the first electrode 11, and the maximum width A of the maximum cross-sectional portion of the tip portion is 20 mm to 40 mm, such as 20 mm, 25 mm, 30 mm, 35 mm or 40 mm, etc.; the extension dimension B of the tip portion along the first direction is 90 mm to 110 mm, such as 90 mm, 95 mm, 100 mm, 105 mm or 110 mm, etc. Fig. 9 As shown, the distance C between the discharge tip and the first electrode in the first direction is 3 mm to 8 mm, the voltage of the first electrode 11 is 0 KV to 5 KV, and the voltage of the second electrode 12 is -11.5 KV to -9.5 KV.

[0091] By means of the size design and voltage control of the tip portion 121, the negative ions released by the discharge tip 1211 can be increased, and the concentration of negative ions in each cubic centimeter of air can reach tens of millions or more, thereby improving the purification and sterilization effect.

[0092] The distance C between the discharge tip 1211 and the first electrode 11 in the first direction X is 3 mm to 8 mm, and the discharge tip 1211 is located on a side of the first electrode 11 close to the second electrode 12. Optionally, the distance C between the discharge tip 1211 and the first electrode 11 in the first direction X is 3 mm, 4 mm, 5 mm, 6 mm or 8 mm, etc.

[0093] The voltage of the first electrode 11 is 0KV to 5KV. The voltage of the first electrode 11 does not need to be too high. Exemplarily, the voltage of the first electrode 11 is 0KV. The first electrode 11 only needs to be grounded, and no high-voltage circuit is required, thereby reducing the use cost of the charging network component 1.

[0094] The voltage of the second electrode 12 is -11.5 KV to -9.5 KV. The second electrode 12 is controlled by negative high voltage so that the discharge tip 1211 releases negative ions.

[0095] In some embodiments of the present invention, Figure 3 As shown, the second electrode 12 includes an electrode needle 12a, and the electrode needle 12a also includes a cylindrical portion 12a1. The tip portion 121 is connected to both axial ends of the cylindrical portion 12a1. The diameter of the cylindrical portion 12a1 is 20 mm to 40 mm.

The second electrode 12 is installed on the support bar 14. The support bar 14 is arranged perpendicular to the opening direction of the frame opening 131.

By providing multiple support bars 14 , the number of second electrodes 12 is also multiple, which is beneficial to improving the negative ion concentration in the charging network component 1 .

The fastener 16 passes through the third fastening hole 1151, the second fastening hole 112 and the first fastening hole 1321 in sequence.

[0112] Thus, the three structures of the protective net 15, the first electrode 11 and the support portion 132 can be fixed to each other by a fastener 16, which can reduce the difficulty of assembly, improve assembly efficiency, save parts, and save manufacturing costs.

[0114] In some embodiments of the present invention, Figure 6 As shown, a cavity is provided on the frame 13 of the charging network component 1, and an elastic conductive sheet 18 and a micro switch 19 are arranged in the cavity. A high-voltage package box cover 17 is provided at the opening of the cavity.

[0115] In some embodiments of the present invention, Figure 1 and Fig.17 As shown, the purification component 100 further includes: an electrostatic network component 2 , which is arranged downstream of the charging network component 1 .

[0116] The electrostatic net component 2 is arranged downstream of the charging network component 1. The charging network component 1 releases a large number of negative ions. When particulate matter in the air passes by, it will be adsorbed by the negative ions and thus carry a negative charge. The charged particulate matter will be adsorbed on the electrostatic net component 2 when passing through the electrostatic net component 2. The electrostatic net component 2 filters and purifies the airflow passing through, thereby reducing dust particles in the airflow and improving air quality.

[0117] The electrostatic net component 2 and the charging network component 1 share a high-voltage package for power supply. The charging network component 1 has an elastic conductive sheet 18, and a micro switch 19 is arranged between the two elastic conductive sheets 18. The electrostatic net component 2 is provided with a conductive contact sheet at the corresponding position of the elastic conductive sheet 18. When the electrostatic net component 2 cooperates with the charging network component 1, the conductive contact sheet simultaneously contacts the elastic conductive sheet 18 and the micro switch 19 on the charging network component 1. At this time, the high-voltage package supplies power to the electrostatic dust collection component and the charging network component 1 at the same time. When the electrostatic net component 2 is pulled out for cleaning, the micro switch 19 automatically resets and pops open, and the high-voltage package stops working, and does not supply power to the charging network component 1 and the electrostatic net component 2, so as to prevent the user from touching the purification component 100 and causing an electric shock accident.

[0118] During normal operation, the charging network component 1 discharges and releases negative ions through the discharge tip 1211. When particles in the air pass by, they will be adsorbed by the negative ions and thus carry a negative charge. Then, when the charged particles pass through the electrostatic network group, they will be adsorbed onto the positive electrode of the electrostatic network group. After working for a period of time, the electrostatic network group can be pulled out and washed with water and can be reused.

[0119] Hereinafter, a purification component 100 according to a specific embodiment of the present invention will be described with reference to the accompanying drawings.

[0120] The charging network component 1 includes a frame 13 and a first electrode 11. The first electrodes 11 are two and are spaced apart along the opening direction of the frame 13. The first electrodes 11 are stainless steel electrode plates, which are respectively installed on both sides of the opening direction of the frame opening 131 of the frame 13. The two stainless steel electrode plates can be designed in a four-square grid, a six-square grid, a nine-square grid, etc. The second electrode 12 is hollowed out in the middle.

[0121] The charged grid assembly 1 also includes a support bar 14 and a second electrode 12. Three support bars 14 are arranged in the frame 13. The support bars 14 are arranged at intervals along the width direction. The support bars 14 define a glue pouring groove 141. Each glue pouring groove 141 is provided with three mounting holes 142 spaced along the length direction of the support bar 14. The second electrode 12 includes nine electrode needles 12a. The electrode needles 12a are inserted and installed in the mounting holes 142. The axial ends of the electrode needles 12a protrude a tip portion 121 toward each first electrode 11. After the electrode needles 12a are positioned and installed in the mounting holes 142, colloid is filled into the glue pouring groove 141 to fix the electrode needles 12a to the support bar 14. After installation, the one-way stainless steel needle is located in the middle of the hollow hole 111 of the stainless steel electrode sheet.

[0122] The discharge tip 1211 at one axial end of the electrode needle 12a forms a discharge module with the corresponding first electrode 11. After power is turned on, the discharge tip 1211 will release negative ions. The discharge tip 1211 at the other axial end of the electrode needle 12a forms a discharge module with the corresponding first electrode 11. After power is turned on, the discharge tip 1211 will release negative ions. Therefore, when the particulate matter in the air passes through the charged network component 1, it can adsorb the released negative ions twice, so that the particulate matter can adsorb more negative ions per unit time, and then when the charged particulate matter passes through the electrostatic network component 2, the adsorption efficiency is higher, thereby improving the purification and dust removal effect.

[0123] The charging network component 1 also includes two guard nets 15. The upper guard net 15, the upper stainless steel electrode plate and the frame 13 are fixedly connected by a series of three screws, and the lower guard net 15, the lower stainless steel electrode plate and the frame 13 are fixedly connected by a series of three screws.

[0127] The other experimental parameters of the charged grid component 1 of the embodiment 1 and the charged grid component of the comparative example 1 are consistent.

It can be intuitively seen that by setting the second electrode 12 as a double-head discharge member 120, the purification effect of the charged grid component 1 can be improved.
