Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0061] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0062] The purification component 100 of the first aspect of the present invention will now be described with reference to the accompanying drawings.

[0063] According to the purification component 100 of this utility model embodiment, such as Figure 1 and Figure 2 As shown, the purification component 100 includes: a mounting frame 10 and a charging unit 40. The mounting frame 10 includes a surrounding frame 1 and mounting strips 2. The surrounding frame 1 surrounds a space S that extends along a first direction F1. The mounting strips 2 are disposed in the space S and extend along a second direction F2 that is perpendicular to the first direction F1. There are multiple mounting strips 2 arranged along a third direction F3 that is perpendicular to the first direction F1. The second direction F2 is perpendicular to the third direction F3. The mounting strips 2 define a glue injection groove 21 that extends along the second direction F2. The two ends of the glue injection groove 21 in the first direction F1 are the groove opening 21a and the groove bottom 21b, respectively. The charging unit 40 includes a first electrode 4 and a second electrode 5. The first electrode 4 is mounted on the mounting strip 2 and includes a circuit board 41 and a discharge needle 42. The circuit board 41 extends along the second direction F2 and is located within the injection groove 21. The discharge needle 42 is disposed on the circuit board 41 and extends along the first direction F1. There are multiple discharge needles 42, which are spaced apart along the second direction F2. The end of the discharge needle 42 away from the circuit board 41 is formed as a discharge tip 42a. The second electrode 5 is mounted on the mounting frame 10. The second electrode 5 and the first electrode 4 are spaced apart along the first direction F1. The second electrode 5 is located on the side facing the discharge tip 42a and forms a hollow hole 51 corresponding to each discharge tip 42a. Figure 3 and Figure 4 As shown, the glue injection groove 21 has a limiting structure 211 for limiting the circuit board 41. The limiting structure 211 is used to prevent the circuit board 41 from moving in the direction from the bottom of the groove 21b to the opening of the groove 21a.

[0064] The mounting frame 10 is the outer frame of the purification component 100. The charged unit 40 is used to purify the flowing air. The charged unit 40 is mounted on the mounting frame 10. The mounting frame 10 includes a surrounding frame 1 and mounting strips 2. The surrounding frame 1 defines a space, and the mounting strips 2 are disposed within the space. The first electrode 4 is mounted on the mounting strip 2. There are multiple mounting strips 2, which are spaced apart along a third direction F3. Correspondingly, the first electrode 4 is disposed on multiple mounting strips 2. The first electrode 4 includes a circuit board 41 and a discharge needle 42. The discharge tip 42a of the discharge needle 42 is energized to generate negative ions. Multiple discharge needles 42 are arranged correspondingly on each mounting strip 2. The multiple discharge needles 42 are spaced apart along the extension direction of the mounting strip 2, and at least one circuit board 41 is arranged corresponding to each mounting strip 2. The circuit board 41 connects the multiple discharge needles 42 in series.

[0065] The first electrode 4 and the second electrode 5 are spaced apart along the first direction F1. The charging unit 40 includes the first electrode 4 and the second electrode 5, which cooperate with each other. After the charging grid assembly is energized, a high-voltage electric field is formed between the discharge tip 42a of the first discharge needle 42 and the second electrode 5. The discharge tip 42a of the discharge needle 42 continuously releases negative ions. The second electrode 5 forms a perforated hole 51 to facilitate airflow. When particulate matter in the air passes through, it is adsorbed by negative ions and becomes negatively charged. The charged particulate matter is easily adsorbed onto the filter element, thereby improving the air quality flowing through the charging unit 40. For example, a dust collection net is set downstream of the charging unit 40. After the airflow flows through the charging unit 40, the particulate matter in the airflow is adsorbed by negative ions and becomes negatively charged. The charged particulate matter is adsorbed onto the dust collection net, thereby reducing dust particles in the airflow, improving air quality, and realizing the air purification function.

[0066] In related technologies, the reliability of the first electrode arrangement on the mounting strip is poor. If the circuit board is not installed stably during the assembly process, the distance between the circuit board and the second electrode will change, which will cause arcing and short circuit between the circuit board and the second electrode, affecting the use of the purification component.

[0067] Therefore, the purification component 100 of this utility model embodiment provides a limiting structure 211 in the glue injection tank 21. The circuit board 41 is installed in the glue injection tank 21 and limited by the limiting structure 211. The limiting structure 211 can prevent the circuit board 41 from moving from the bottom 21b of the tank to the opening 21a. The bottom 21b of the glue injection tank 21 restricts the movement of the circuit board 41 from the opening 21a to the bottom 21b of the tank. This can improve the installation stability of the first electrode 4, stabilize the distance between the circuit board 41 and the second electrode 5, reduce the occurrence of arcing and short circuits, and improve the working reliability of the purification component 100.

[0068] According to the purification component 100 of this utility model embodiment, by setting a limiting structure 211 in the glue injection groove 21, the installation stability of the first electrode 4 can be improved, the distance between the circuit board 41 and the second electrode 5 can be stabilized, the phenomenon of arcing and short circuit can be reduced, and the working reliability of the purification component 100 can be improved.

[0069] In some embodiments of this utility model, such as Figure 2 , Figure 3 and Figure 4 As shown, the second direction F2 is the length direction of the glue injection groove 21, the third direction F3 is the width direction of the glue injection groove 21, and the limiting structure 211 includes limiting ribs 2111 located inside the glue injection groove 21 and disposed on both sides of the circuit board 41 along the width direction of the glue injection groove 21.

[0070] The limiting ribs 2111 are located on both sides of the circuit board 41 in the third direction F3. The limiting structure 211 clamps and limits the circuit board 41 from both sides, preventing the circuit board 41 from moving along the bottom of the groove 21b towards the opening 21a. Furthermore, the limiting ribs 2111 located on both sides of the circuit board 41 in the third direction F3 can also limit the movement of the circuit board 41 in the third direction F3, further improving the installation stability of the circuit board 41.

[0071] In some embodiments of this utility model, such as Figure 4 , Figure 5 and Figure 6 As shown, the circuit board 41 is provided with a plurality of limiting ribs 2111 on each side of the width direction of the glue injection groove 21, which are spaced apart along the length direction of the glue injection groove 21; wherein, the limiting ribs 2111 on both sides of the width direction of the glue injection groove 21 are arranged opposite to each other or staggered.

[0072] Multiple limiting ribs 2111 are provided on one side of the width of the glue injection groove 21. The limiting ribs 2111 are spaced apart along the length of the glue injection groove 21. The circuit board 41 is subjected to uniform force. The limiting ribs 2111 limit the circuit board 41 as a whole, reducing the occurrence of the circuit board 41 moving locally along the direction from the bottom of the groove 21b to the opening of the groove 21a.

[0073] Optionally, the limiting ribs 2111 on both sides of the width direction of the glue injection groove 21 are arranged opposite to each other in the third direction F3, and the limiting ribs 2111 clamp the circuit board 41 in pairs; or, alternatively, the limiting ribs 2111 on both sides of the width direction of the glue injection groove 21 are arranged at intervals in the second direction F2, which can also limit the circuit board 41 and prevent the circuit board 41 from moving in the direction from the bottom of the groove 21b to the opening of the groove 21a.

[0074] In some embodiments of this utility model, such as Figure 5As shown, limiting ribs 2111 are provided at both ends of the glue injection groove 21 along its length. The limiting ribs 2111 limit the end of the circuit board 41 in the second direction F2, thereby preventing the circuit board 41 from moving along the direction from the bottom of the groove 21b to the opening of the groove 21a, thus achieving the limiting.

[0075] In some embodiments of this utility model, such as Figure 2 and Figure 9 As shown, the mounting strip 2 includes two side plates 22 extending along the second direction F2 and arranged along the third direction F3. An injection groove 21 is defined between the two side plates 22. The two side plates 22 meet and connect at one end in the first direction F1 to form a sealing end 221. The other ends of the two side plates 22 are separated and spaced apart to define a groove 21a. The side plates 22 include a guide section 222. The guide sections 222 of the two side plates 22 extend from the sealing end 221 in a direction away from each other, so that the distance between the two guide sections 222 gradually increases.

[0076] Two side plates 22 are connected at one end in the first direction F1 to form a sealing end 221, and the other ends of the two side plates 22 are spaced apart in the first direction F1 to define an injection groove 21 with a groove 21a. The sealing end 221 defines the bottom 21b of the injection groove 21.

[0077] Airflow flows through the purification component 100 in the first direction F1. The side plate 22 not only serves to install the first electrode 4, but also guides the airflow. The side plate 22 includes a guide section 222. The guide sections 222 of the two side plates 22 extend from the sealing end 221 toward the slot opening 21a. The two side plates 22 extend in the direction away from each other along the extension direction. The airflow direction is from the bottom of the slot 21b to the slot opening 21a. By setting the guide section 222, the obstruction to the airflow can be reduced and the airflow can be improved.

[0078] In some embodiments of this utility model, such as Figure 2 and Figure 9 As shown, the side panel 22 also includes a closing section 223, which extends from the guide section 222 toward the end away from the sealing end 221 and is deflected toward the other side panel 22 relative to the guide section 222.

[0079] The end of the constriction section 223 away from the flow guide section 222 is spaced apart and defines the groove 21a. The area of ​​the glue injection groove 21 at the flow guide section 222 gradually increases along the first direction F1, and the area of ​​the glue injection groove 21 at the constriction section 223 gradually decreases along the first direction F1, which is beneficial for limiting the circuit board 41 installed in the glue injection groove 21.

[0080] In some embodiments of this utility model, such as Figure 1 and Figure 9As shown, the mounting strip 2 is provided with a support rib 23, which is located between the two guide sections 222. The circuit board 41 is supported on the side of the support rib 23 facing the slot 21a.

[0081] It is understandable that the guide sections 222 gradually extend away from each other from the bottom 21b towards the opening 21a. Therefore, the area of ​​the glue injection groove 21 is smallest at the position of the guide section 222 away from the opening 21a. This space is insufficient to install the circuit board 41. Therefore, the circuit board 41 cannot directly contact the bottom 21b, but is connected to the guide section 222. Therefore, in some embodiments of this utility model, a support rib 23 is provided between the two guide sections 222. The support rib 23 is used to support the circuit board 41, which can improve the installation stability of the circuit board 41 and the mounting strip 2, and reduce the situation of dislocation and shaking that occurs when the circuit board 41 is only connected to the guide section 222.

[0082] In some embodiments of this utility model, such as Figure 5 and Figure 6 As shown, there are multiple support ribs 23, which are spaced apart along the second direction F2.

[0083] The support ribs 23 are spaced along the length of the glue injection groove 21, so that the circuit board 41 is subjected to uniform force and provides overall support for the circuit board 41, reducing the occurrence of local instability in the installation of the circuit board 41.

[0084] In some embodiments of this utility model, the limiting structure 211 includes limiting ribs 2111 located in the glue injection groove 21 and along the third direction F3, that is, along the width direction of the glue injection groove 21 on both sides of the circuit board 41. The limiting ribs 2111 extend from the supporting ribs 23 toward the groove opening 21a.

[0085] By integrating the limiting rib 2111 with the supporting rib 23, the structural strength of the limiting rib 2111 can be improved, which is beneficial to improving the limiting effect on the circuit board 41, and also helps to simplify the structure of the mounting strip 2 and reduce manufacturing difficulty.

[0086] In some embodiments of this utility model, such as Figure 9 As shown, the glue injection groove 21 is provided with insulating glue, which includes an insulating part 71 on the side of the circuit board 41 facing the groove opening 21a. The height L of the insulating part 71 in the first direction F1 is greater than or equal to 3mm.

[0087] After the circuit board 41 is installed on the mounting strip 2, it is fixed in the glue injection groove 21 by glue injection. After glue injection, an insulating part 71 is formed on the side of the circuit board 41 facing the groove opening 21a. The height L of the insulating part 71 in the first direction F1 is greater than or equal to 3mm. While being fixed by glue injection, it can provide insulation protection and improve the safety and working stability of the circuit board 41.

[0088] Optionally, the height L of the insulating part 71 in the first direction F1 is 3mm, 3.5mm, 4mm, 4.5mm, 5mm, etc.

[0089] By setting a limiting structure 211 to limit the circuit board 41, the movement of the circuit board 41 towards the groove 21a during the glue injection process is prevented. This can reduce the problem of insufficient thickness of the insulating part 71, thereby improving the installation stability of the first electrode 4. The distance between the circuit board 41 and the second electrode 5 is stable, which can reduce the occurrence of arcing and short circuits and improve the working reliability of the purification component 100.

[0090] In some embodiments of this utility model, such as Figure 2 , Figure 5 and Figure 9 As shown, the mounting strip 2 has a first support post 25, which extends toward the second electrode 5 to support the second electrode 5 and prevent the second electrode 5 from moving toward the direction close to the first electrode 4 along the first direction F1.

[0091] By setting the first support column 25 to support the second electrode 5, the gap between the second electrode 5 and the circuit board 41 can be prevented from becoming smaller due to deformation and collapse of the second electrode 5.

[0092] Some embodiments of this utility model, by setting a first support column 25 on the mounting strip 2, not only prevent the circuit board 41 from moving toward the second electrode 5 through the limiting structure 211, but also restrict the movement of the second electrode 5 toward the circuit board 41 through the first support column 25, so that the distance between the circuit board 41 and the second electrode 5 is stable, which can reduce the occurrence of arcing and short circuit, and improve the working reliability of the purification component 100.

[0093] In some embodiments of this utility model, such as Figure 5 As shown, each mounting strip 2 supports a single second electrode 5 by at least a plurality of first support posts 25 spaced apart along the second direction F2. That is, there are multiple first support posts 25 on each mounting strip 2, and at least some of the first support posts 25 are spaced apart along the second direction F2.

[0094] The first support portion consists of multiple parts, and at least some of the first support columns 25 are spaced apart along the second direction F2. The first support columns 25 support the second electrode 5 which is opposite to the length direction of the circuit board 41. The first support columns 25 have strong support stability, and the second electrode 5 is subjected to relatively uniform force. This can prevent the second electrode 5 from collapsing due to local deformation opposite to the circuit board 41, which would cause the distance between the second electrode 5 and the circuit board 41 to decrease.

[0095] In some embodiments of this utility model, such as Figure 1 , Figure 8 and Figure 9As shown, the first electrode 4 is provided with second electrodes 5 on both sides in the first direction F1, the discharge needle 42 has a discharge tip 42a facing each side of the second electrode 5, and the mounting strip 2 extends with a first support column 25 facing each side of the second electrode 5.

[0096] There are two second electrodes 5, which are respectively placed on both sides of the first electrode 4 in the first direction F1. The discharge needle 42 has a discharge tip 42a on each side of the second electrode 5, and the discharge tips 42a with different orientations are respectively matched with the two second electrodes 5. When particulate matter in the air passes through the purification component 100, it can adsorb the negative ions released by the two discharge tips 42a twice, which can increase the probability that the particulate matter in the airflow is adsorbed by negative ions and carries negative ions, so that the particulate matter adsorbs more negative ions per unit time. As a result, when charged particulate matter passes through the filter, the adsorption efficiency is higher, thereby improving the purification and dust removal effect.

[0097] There are two second electrodes 5. Correspondingly, the mounting strip 2 extends a first support column 25 towards each side of the second electrode 5. The first support column 25 supports the corresponding second electrode 5 and prevents the corresponding second electrode 5 from moving towards the direction of the first electrode 4 along the first direction F1.

[0098] In some embodiments of this utility model, such as Figure 2 and Figure 9 As shown, the mounting strip 2 includes two side plates 22 extending along the second direction F2 and arranged along the third direction F3. A glue injection groove 21 is defined between the two side plates 22. The two side plates 22 meet and connect at one end in the first direction F1 to form a sealing end 221. The other ends of the two side plates 22 are separated and spaced apart to define a groove 21a. The mounting strip 2 has a first support post 25 at each end in the first direction F1. The sealing end 221 extends with a first support post 25 toward the second electrode 5 on the adjacent side. The end of each side plate 22 away from the sealing end 221 extends with a first support post 25 toward the second electrode 5 on the adjacent side.

[0099] Two side plates 22 are connected at one end in the first direction F1 to form a sealing end 221, and the other ends of the two side plates 22 are spaced apart in the first direction F1 to define an injection groove 21 with a groove 21a. The sealing end 221 defines the bottom 21b of the injection groove 21.

[0100] Airflow flows through the purification component 100 in the first direction F1. The side plate 22 not only serves to install the first electrode 4, but also guides the airflow. The side plate 22 includes a guide section 222. The guide sections 222 of the two side plates 22 extend from the sealing end 221 toward the slot opening 21a. The two side plates 22 extend in the direction away from each other along the extension direction. The airflow direction is from the bottom of the slot 21b to the slot opening 21a. By setting the guide section 222, the obstruction to the airflow can be reduced and the airflow can be improved.

[0101] A first support post 25, located at the sealing end 221, extends from the sealing end 221 in a direction away from the slot opening 21a, supporting the second electrode 5 located on one side of the sealing end 221. A second support post 25, located at one end of the slot opening 21a, extends from the bottom of the slot 21b towards the slot opening 21a, supporting the second electrode 5 located on one side of the slot opening 21a. By providing two first support posts 25 to support the two second electrodes 5 respectively, the reduction in the distance between the second electrode 5 and the circuit board 41 due to deformation and collapse of the second electrode 5 can be prevented.

[0102] In some embodiments of this utility model, such as Figure 2 and Figure 9 As shown, the first support column 25, located at the center of the sealing end 221, is provided on each mounting strip 2 in the third direction F3. Since the side plates 22 are spaced apart away from the sealing end 221, they cannot be positioned at the center of the two side plates 22. The first support column 25, located at one end of the slot 21a, is distributed on both side plates 22 and faces each other along the third direction F3, which improves the stability of the first support column 25 in supporting the second electrode 5.

[0103] In some embodiments of this utility model, such as Figure 10 and Figure 11 As shown, the second electrode 5 has a plurality of first plate portions 52 extending along a second direction F2 and a plurality of second plate portions 53 extending along a third direction F3. The first plate portions 52 and the second plate portions 53 are intersected and connected, and a hollow hole 51 is defined between the first plate portions 52 and the second plate portions 53.

[0104] The first plate portion 52 extends in the same direction as the mounting strip 2, and the first plate portion 52 defines a cutout hole 51 that is directly opposite to the discharge pin 42 on the mounting strip 2. Therefore, the first plate portion 52 and the mounting strip 2 are offset in the third direction F3 and are not directly opposite in the first direction F1. The distance between the first plate portion 52 and the circuit board 41 in the mounting strip 2 is relatively far.

[0105] The second plate portion 53 extends along the third direction F3 and has an intersection with the mounting strip 2 in the first direction F1. The intersection of the second plate portion 53 and the circuit board 41 is the closest position between the circuit board 41 and the second motor.

[0106] Therefore, in some embodiments of this utility model, such as Figure 10 and Figure 11 As shown, in the first direction F1, a first support column 25 is provided at the intersection of the second plate portion 53 and the mounting strip 2 to support the second electrode 5 and prevent the second electrode 5 from moving in the first direction F1 toward the direction closer to the first electrode 4.

[0107] In some embodiments of this utility model, such as Figure 9 As shown, the distance H between the second electrode 5 and the discharge tip 42a is 3-8 mm.

[0108] By setting the distance H between the discharge tip 42a and the second electrode 5 to 3-8mm, the negative ions released by the discharge tip 42a can be increased, resulting in a concentration of over ten million negative ions per cubic centimeter of air, which can improve the purification and sterilization effect.

[0109] Optionally, the distance H between the second electrode 5 and the discharge tip 42a can be 3mm, 4mm, 5mm, 6mm or 8mm, etc.

[0110] In some embodiments of this utility model, the voltage of the first electrode 4 is -11.5KV to -9.5KV, and the voltage of the second electrode 5 is 0KV to 5KV.

[0111] In some embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 12 As shown, the mounting frame 10 also includes a pressure cap 3, which is arranged with the frame 1 along the first direction F1. The second electrode 5 is disposed between the pressure cap 3 and the first electrode 4. The pressure cap 3 is connected to the frame 1, and the pressure cap 3 has a second support column 31. The second support column 31 extends toward the direction of the second electrode 5 to support the second electrode 5 and prevent the second electrode 5 from moving away from the first electrode 4 along the first direction F1.

[0112] The pressure cap 3 is connected to the frame 1. The pressure cap 3 protects the first electrode 4 and the second electrode 5 inside, which can improve the working stability of the purification component 100. In addition, the pressure cap 3 can also limit the movement of the second electrode 5. The second electrode 5 is located between the pressure cap 3 and the first electrode 4. The pressure cap 3 is provided with a second support column 31. The second support column 31 supports the second electrode 5 from the direction of the second electrode 5 toward the first electrode 4, thereby restricting the movement of the second electrode 5 in the first direction F1 away from the first electrode 4, which can improve the installation stability of the second electrode 5.

[0113] In some embodiments of this utility model, such as Figure 2 , Figure 9 and Figure 11 As shown, the mounting frame 10 also includes a pressure cap 3, which is arranged with the frame 1 along the first direction F1. The second electrode 5 is disposed between the pressure cap 3 and the first electrode 4. The pressure cap 3 is connected to the frame 1, and the pressure cap 3 has a second support column 31. The second support column 31 extends toward the direction of the second electrode 5 to support the second electrode 5 and prevent the second electrode 5 from moving away from the first electrode 4 along the first direction F1. The first support column 25 and the second support column 31 are arranged opposite each other along the first direction F1.

[0114] The second support column 31 restricts the second electrode 5 from moving away from the first electrode 4 along the first direction F1, and the first support column 25 restricts the second electrode 5 from moving closer to the first electrode 4 along the first direction F1. The first support column 25 and the second support column 31 clamp the second electrode 5, which can improve the installation stability of the second electrode 5 and reduce the collapse and deformation of the second electrode 5.

[0115] In some embodiments of this utility model, such as Figure 2 and Figure 11 As shown, the discharge needle 42 includes a first needle segment 421 protruding from the circuit board 41 on the side facing the slot 21a, and the end of the first needle segment 421 near the slot 21a forms a discharge tip 42a; and / or, the discharge needle 42 includes a second needle segment 422 protruding from the circuit board 41 on the side facing the bottom of the slot 21b, the second needle segment 422 penetrating the bottom of the slot 21b in a direction away from the slot 21a, and the end of the second needle segment 422 away from the slot 21a forms a discharge tip 42a.

[0116] The discharge needle 42 includes a first needle segment 421 protruding from the circuit board 41 on the side facing the slot 21a. The second electrode 5 is disposed on the side of the slot 21a of the mounting strip 2. The end of the first needle segment 421 near the slot 21a forms a discharge tip 42a that cooperates with the second electrode 5.

[0117] The discharge needle 42 includes a second needle segment 422 protruding from the circuit board 41 towards the bottom of the slot 21b. The second electrode 5 is disposed on one side of the bottom of the slot 21b of the mounting strip 2. The end of the second needle segment 422 away from the slot opening 21a forms a discharge tip 42a that mates with the second electrode 5. Figure 5 and Figure 6 As shown, the bottom 21b of the glue injection groove 21 has a through hole 26, and part of the second needle segment 422 extends through the through hole 26 in a direction away from the groove opening 21a.

[0118] In some embodiments of this utility model, such as Figure 2As shown, the discharge needle 42 includes a first needle segment 421 and a second needle segment 422, which are integrally connected. There are two second electrodes 5, which are respectively placed on both sides of the first electrode 4 in the first direction F1.

[0119] There are two second electrodes 5, which are respectively placed on both sides of the first electrode 4 in the first direction F1. The discharge needle 42 includes a first needle segment 421 and a second needle segment 422. The discharge needle 42 has a discharge tip 42a facing each side of the second electrode 5. The discharge tips 42a in different directions are respectively matched with the two second electrodes 5.

[0120] When particulate matter in the air passes through the purification component 100, it can adsorb the negative ions released by the two discharge tips 42a twice, which can increase the probability that particulate matter in the airflow is adsorbed by negative ions and carries negative ions, so that the particulate matter adsorbs more negative ions per unit time. As a result, when charged particulate matter passes through the filter, the adsorption efficiency is higher, thereby improving the purification and dust removal effect.

[0121] By integrating the first needle segment 421 and the second needle segment 422, space can be saved compared to setting a separate discharge needle 42 for each second electrode 5. Moreover, the number of components included in the charging unit 40 can be reduced, which is beneficial for assembly. This improves the assembly efficiency of the purification component 100 and reduces production costs.

[0122] In some embodiments of this utility model, such as Figure 13 As shown, the frame 1 includes a first frame 11 and a second frame 12 spaced apart along the second direction F2. The second frame 12 is equipped with a first conductive pin 61 and a second conductive pin 62 spaced apart along the third direction F3. Each mounting strip 2 contains a first electrode 4, such as...

Figure 14 As shown, the circuit board 41 of one of the plurality of first electrodes 4 closest to the first conductive pin 61 is connected to the second conductive pin 62 via a second conductive line 64 on the side near the second frame 12, as shown. Figure 15 and Figure 16 As shown, the two second electrodes 5 are connected by a third conductive line 65 on the side near the second frame 12, and the third conductive line 65 is connected to the second conductive pin 62.

[0123] The first conductive pin 61 is used to electrically connect with the first electrode 4, and the second conductive pin 62 is used to electrically connect with the second electrode 5. After the first electrode 4 and the second electrode 5 are installed in the frame 1, the electrical connection is completed. The first conductive pin 61 and the second conductive pin 62 are then connected to the external power supply component.

The circuit boards 41 of the multiple first electrodes 4 are connected by second conductive lines 64, and a first conductive line 63 connects one circuit board 41 to a first conductive pin 61. There are two second electrodes 5, which are connected by a third conductive line 65, and the third conductive line 65 is connected to a second conductive pin 62.
