Conversely, when the locking unit is in the unlocked state, the relative movement of the first filter element and the connecting seat can cause the guide structure and the guide mating structure to separate, thereby disassembling the first filter element and the connecting seat. This solution can limit the connection of the first filter element and the connecting seat in multiple directions and can improve the efficiency of disassembly and assembly operations, making it highly practical.

Detailed Implementation

[0056] To make the above-described objects, features, and advantages of this disclosure more apparent and understandable, specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. Although some embodiments of this disclosure are shown in the drawings, it should be understood that this disclosure can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this disclosure. It should be understood that the accompanying drawings and embodiments of this disclosure are for illustrative purposes only and are not intended to limit the scope of protection of this disclosure.

[0057] Those skilled in the art should understand that, unless explicitly stated in the context, or if the context reveals that it has a clear limitation, the following should be understood: the term "comprising" and its variations as used herein are open-ended inclusion, meaning "including but not limited to"; the term "based on" means "at least structurally based on"; the term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments"; the term "optionally" means "optional embodiments"; the concepts such as "first," "second," etc., are used only to distinguish different devices, modules, or units, and are not used to limit the order of functions performed by these devices, modules, or units or their interdependencies, nor should they be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. A feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0058] Furthermore, the illustrative expressions of the terms used in this specification do not necessarily refer to the same embodiments or implementations. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0059] Electrical equipment, such as inverters, requires the installation of filter components. These filter components typically include a filter element and a mounting base 2 for mounting the filter element. The filter element has a through hole, and the mounting base 2 has a threaded hole. Screws pass through the through hole and are threadedly connected to the threaded hole. The applicant's research found that although this method can achieve the installation of the filter element, it requires the removal and installation of a large number of screws. The disassembly and / or installation process is cumbersome, time-consuming, and labor-intensive, resulting in low work efficiency.

[0060] refer to Figure 1-9 Main reference Figure 2 The present disclosure provides a filter component, which includes a first filter element 1 and a connecting seat 2 distributed in a first direction W.

[0061] One of the first filter element 1 and the connecting seat 2 is provided with a guide structure 31, and the other is provided with a guide fitting structure 32. When the guide structure 31 is accommodated in (or can be understood as inserted into) the guide fitting structure 32, the first filter element 1 and the connecting seat 2 can move relative to each other in the second direction U.

[0062] One of the first filter element 1 and the connecting seat 2 is provided with a positioning structure 41, and the other is provided with a positioning and fitting structure 42. The positioning and fitting structure 42 is located on the movement path of the positioning structure 41 in the second direction U.

[0063] A locking unit 5 is provided between the first filter element 1 and the connecting seat 2;

[0064] When the positioning and mating structure 42 and the positioning structure 41 are positioned and connected, the first filter element 1 and the connecting seat 2 are limited and connected in the first direction W. The first filter element 1 is connected to the connecting seat 2 through the locking unit 5.

[0065] It should be noted that this specification defines a first direction, a second direction, and a third direction, which are set in pairs and intersecting each other. For ease of explanation, the W-axis, U-axis, and V-axis are defined to be perpendicular to each other, and the first direction, second direction, and third direction are set in pairs and perpendicular to each other. In this case, the first direction W refers to the direction parallel to the W-axis in the diagram, not specifically the direction pointed by the arrow on the W-axis; the second direction U refers to the direction parallel to the U-axis in the diagram, not specifically the direction pointed by the arrow on the U-axis; and the third direction V refers to the direction parallel to the V-axis in the diagram, not specifically the direction pointed by the arrow on the V-axis. However, it should be understood that in practical applications, while the W-axis, U-axis, and V-axis are perpendicular to each other, the first direction, second direction, and third direction are not limited to being perpendicular to each other. In this case, the aforementioned "parallelism" is not limited to absolute parallelism; the corresponding direction can have a certain angle with the corresponding coordinate axis. For example, the first direction and the W-axis can have an angle range of ±15°.

[0066] Specifically, the guide structure 31 and the guide mating structure 32 constitute a guide connection unit between the first filter element 1 and the connecting seat 2. In this specification, the following description will use the example of the first filter element 1 having a guide structure 31 and the connecting seat 2 having a guide mating structure 32. However, it should be understood that the arrangement can also be such that the first filter element 1 has a guide mating structure 32 and the connecting seat 2 has a guide structure 31; this embodiment does not impose any limitations on this. Since the guide structure 31 and the guide mating structure 32 are relatively movable in the second direction U, when the guide structure 31 is housed within the guide mating structure 32, the guide mating structure 32 can initially position the guide structure 31. The guide mating structure 32 can guide the relative movement of the guide structure 31 in the second direction U to a certain extent. That is, when the guide structure 31 is housed within the guide mating structure 32, the guide structure 31 and the guide mating structure 32 cooperate to guide the movement of the first filter element 1 and the connecting seat 2 in the second direction U. The configuration of the guide connection unit is not limited and will be described exemplarily later.

[0067] Specifically, the positioning structure 41 and the positioning mating structure 42 constitute the positioning connection unit of the first filter element 1 and the connecting seat 2. In this specification, the following description will take the example of the first filter element 1 having a positioning structure 41 and the connecting seat 2 having a positioning mating structure 42. However, it should be understood that the arrangement can also be that the first filter element 1 has a positioning mating structure 42 and the connecting seat 2 has a positioning structure 41. This embodiment does not impose any restrictions on this. Since the positioning mating structure 42 is located on the movement path of the positioning structure 41 in the second direction U, with the guide structure 31 housed in the guide mating structure 32, the first filter element 1 and the connecting seat 2 can move relative to each other in the second direction U until the positioning mating structure 42 and the positioning structure 41 are positioned and connected. When the positioning mating structure 42 and the positioning structure 41 are in the positioned connection state, the relative positions of the first filter element 1 and the connecting seat 2 in the second direction U are positioned.

[0068] When the guide structure 31 is inserted into the guide mating structure 32, a force can be applied to the first filter element 1 and the connecting seat 2, so that the first filter element 1 and the connecting seat 2 move relative to each other in the second direction U, thereby the guide structure 31 and the guide mating structure 32 can move relative to each other in the second direction U until the positioning structure 41 moves to be positioned and connected with the positioning mating structure 42.

[0069] It should be understood in the art that the positioning structure 41 and the positioning mating structure 42 are positioned and connected in the second direction U, meaning that the positioning structure 41 and the positioning mating structure 42 abut against each other in the second direction U, thereby achieving relative positioning of the first filter element 1 and the connecting seat 2 in the second direction U. Conversely, before the positioning structure 41 and the positioning mating structure 42 are positioned and connected in the second direction U, the first filter element 1 and the connecting seat 2 can move relative to each other in the second direction U.

[0070] Accordingly, when the positioning and fitting structure 42 and the positioning structure 41 are positioned and connected, the first filter element 1 and the connecting seat 2 are limited and connected in the first direction W. This limited connection in the first direction W means that the positioning and fitting structure 42 and the positioning structure 41 abut against each other in the first direction W, restricting the relative movement and separation of the first filter element 1 and the connecting seat 2 in the first direction W. The location and method of the limited connection are not considered limiting and will be explained exemplarily later.

[0071] Thus, in the filter component of this disclosure, one of the first filter element 1 and the connecting seat 2 is provided with a guide structure 31, and the other is provided with a guide mating structure 32. When the guide structure 31 is housed in the guide mating structure 32, the guide structure 31 and the guide mating structure 32 can move relative to each other in the second direction U. That is, the first filter element 1 and the connecting seat 2 can move relative to each other in the second direction U. When the first filter element 1 and the connecting seat 2 move relative to each other in the second direction U until the positioning structure 41 moves to be positioned and connected with the positioning mating structure 42, the relative position of the first filter element 1 and the connecting seat 2 in the second direction U can be achieved. When the positioning mating structure 42 is positioned and connected with the positioning structure 41, the first filter element... The first filter element 1 and the connecting seat 2 are limited in the first direction W, which can limit the relative position of the first filter element 1 and the connecting seat 2 in the first direction W, and prevent them from separating in the first direction W. The first filter element 1 is connected to the connecting seat 2 through the locking unit 5, so that the first filter element 1 and the connecting seat 2 are assembled. Conversely, when the locking unit 5 is in the unlocked state, the guide structure 31 and the guide mating structure 32 can be separated by the relative movement of the first filter element 1 and the connecting seat 2, so as to disassemble the first filter element 1 and the connecting seat 2. This solution can realize the connection limitation of the first filter element 1 and the connecting seat 2 in multiple directions, and can improve the efficiency of the disassembly and assembly operations, which is highly practical.

[0072] It should be understood here that when the positioning and mating structure 42 and the positioning structure 41 are positioned and connected, the first filter element 1 and the connecting seat 2 can be connected by a limiting connection unit to ensure that the relative positions of the first filter element 1 and the connecting seat 2 in the first direction W are limited. This will be described later in conjunction with the embodiments. The limiting connection unit may include a first limiting connection unit, a second limiting connection unit, and a third limiting connection unit, etc., and each limiting unit includes an abutting part and an abutting mating part.

[0073] like Figure 1-9 In the embodiments shown, please refer to the specific examples. Figure 2-3 In an optional embodiment of the guide connection unit, the guide structure 31 includes an insertion structure 311, and the guide mating structure 32 includes a socket structure 321. The insertion structure 311 extends along the first direction W and is accommodated within the socket structure 321. The dimension of the socket structure 321 in the second direction U is greater than the dimension of the insertion structure 311 in the second direction U.

[0074] Specifically, the insertion structure 311 is inserted into the socket structure 321 along the first direction W, and the dimensions of the socket structure 321 in the second direction U can be referenced. Figure 3 Let's interpret D1 as follows: D1 is the minimum inner diameter of the insertion structure 321 in the second direction U. The dimensions of the insertion structure 311 in the second direction U can be referenced. Figure 3Let D2 be understood as the maximum outer diameter of the insertion structure 311 in the second direction U.

[0075] In the scheme disclosed herein, in the first direction W, the first filter element 1 is located in the positive direction of the connecting seat 2 corresponding to the W axis, and this will be used as an example for subsequent explanations. When the insertion structure 311 is inserted into the insertion hole structure 321, the two are slidably connected in the second direction U, and the relative position stability of the two in the third direction V is relatively high.

[0076] like Figure 3 As shown, in this case, optionally, in the first direction W, the end of the insertion structure 311 near the connecting seat 2 is provided with a first abutting part 611, and the end face of the insertion hole structure 321 near the first abutting part 611 is provided with a first abutting mating part 621; when the positioning mating structure 42 and the positioning structure 41 are positioned and connected, the first abutting part 611 and the first abutting mating part 621 are limited and connected in the first direction W.

[0077] like Figure 3 , 18 As shown, exemplarily, in the second direction U, the first abutting part 611 protrudes from the insertion structure 311, and the first abutting mating part 621 is located on the end face of the insertion hole structure 321; when the positioning mating structure 42 and the positioning structure 41 are positioned and connected, the first abutting part 611 and the first abutting mating part 621 abut in the first direction W.

[0078] like Figure 26 As shown, by way of example, the insertion structure 311 may be provided with a bent portion in its extending direction. The bent portion may be bent in a way such as tilting or bending. The first abutment portion 611 is located on the side wall of the bent portion near the connecting seat 2. Figure 26 In the middle, the insertion structure 311 includes a first segment and a second segment distributed sequentially along the negative direction of the W axis. The second segment is inclined relative to the first segment, and the second segment constitutes the aforementioned bent portion.

[0079] The first limiting connection unit may include the first abutting part 611 and the first abutting mating part 621.

[0080] It should be understood that the insertion hole structure 321 is also used for the passage of the first abutting part 611. The insertion hole structure 321 is inserted into the end of the insertion structure 311 where the first abutting part 611 is located, until the first abutting part 611 has completely passed through the insertion hole structure 321, at which point the guide structure 31 is accommodated in the guide fitting structure 32. When the guide structure 31 is accommodated in the guide fitting structure 32, and the positioning structure 41 is positioned in conjunction with the positioning fitting structure 42, the relative positions of the first filter element 1 and the connecting seat 2 in the second direction U can be achieved; while when the positioning fitting structure 42 is positioned in conjunction with the positioning structure 41, the first abutting part 611 and the first abutting fitting part 621 are in abutting state in the first direction W.

[0081] Thus, the arrangement of the first abutting part 611 and the first abutting mating part 621 can improve the connection strength between the first filter element 1 and the connecting seat 2 in the first direction W at the insertion structure 321. The structure is simple and highly practical.

[0082] like Figure 3 As shown, optionally, the positioning structure 41 includes a first positioning part 411, and the positioning mating structure 42 includes a first positioning mating part 421. In the second direction U, the first positioning mating part 421 is located on the inner wall of the insertion hole structure 321, and the first positioning part 411 is located on the surface of the insertion structure 311 near the first positioning mating part 421.

[0083] In other words, when the end of the insertion structure 311 containing the first abutting part 611 is inserted into the socket structure 321, and the first abutting part 611 is not located within the socket structure 321, when the first filter element 1 and the connecting seat 2 are connected in the second direction by, for example, the locking unit 5 described later, the first filter element 1 and the connecting seat 2 can move relative to each other in the second direction U until the first positioning mating part 421 abuts against the first positioning part 411 in the second direction U. When the first positioning mating part 421 abuts against the first positioning part 411 in the second direction U, the first abutting part 611 and the first abutting mating part 621 are in a state of abutting in the first direction W. The locking unit 5 completes the connection operation of the first filter element 1 and the connecting seat 2, thereby achieving a better connection lock for the first filter element 1 and the second filter element 92 at the insertion structure 311, resulting in a high degree of connection stability.

[0084] like Figure 2 and Figure 7 As shown, optionally, the first filter element 1 is provided with a cavity 11, an opening 13 and a filter hole 12; the opening 13 and the filter hole 12 are respectively connected to the cavity 11, the opening 13 faces the connecting seat 2, and the connecting seat 2 is provided with a communication port 21 that communicates with the opening 13.

[0085] like Figure 8As shown, by way of example, the first filter element 1 has a box structure, which is formed by multiple plates. The box structure has an opening 13, and at least one of the multiple plates is provided with a filter hole 12.

[0086] For example, the first filter element 1 has a setting plate 14 and a second plate 15 disposed opposite to each other, and also has a third plate 16 adjacent to the setting plate 14. It should be understood that in this case, the position of the insertion structure 311 can be set as needed, and this disclosure does not impose any restrictions on the specific position of the guide structure 31 (corresponding to the insertion structure 311). For example, in one embodiment, referring to... Figure 8 A guide structure 31 (corresponding to the insertion structure 311) can be provided on the second plate 15, for example in Figure 10-14 In the embodiments shown, please refer to the specific examples. Figure 14 ,exist Figure 15-18 In the embodiments shown, please refer to the specific examples. Figure 18 Alternatively, an insertion structure 311 can be provided on the third plate 16.

[0087] Thus, when the first filter element 1 is connected to the connecting seat 2, it helps to form an airflow path (such as a directional airflow path) between the connecting port 21 and the filter hole 12, which can effectively prevent external dust, particulate matter and other pollutants from entering the equipment. The structure is simple and highly practical.

[0088] like Figure 2 As shown, optionally, in the second direction U, one end of the connecting seat 2 is provided with a first plate 22, the first plate 22 is located inside or outside the cavity 11, the first filter element 1 has a setting plate 14, the setting plate 14 is arranged opposite to the first plate 22; the locking unit 5 is connected to the first plate 22 and the setting plate 14 respectively to realize the relative position locking of the first plate 22 and the setting plate 14.

[0089] Specifically, the side plate of the first filter element 1 opposite to the first plate 22 is the setting plate 14. For example... Figure 2 In the illustrated embodiment, the first plate 22 is shown to be located outside the cavity 11, as shown in the example. Figure 19-24 In the embodiments shown, please refer to the specific examples. Figure 21 This shows the situation where the first plate 22 is located inside the cavity 11.

[0090] This configuration allows for a reasonable placement of the locking unit 5, facilitating its structural design.

[0091] like Figure 6As shown, optionally, the locking unit 5 includes a first connector 51, and the first plate 22 and the setting plate 14, the one furthest from the cavity 11 (i.e. the one located on the outer side) is provided with a first connecting hole 52; wherein, the first connector 51 passes through the first connecting hole 52 and is detachably fixedly connected to the first connecting hole 52, and the first connector 51 abuts against the one of the first plate 22 and the setting plate 14 that is closer to the cavity 11 (i.e., the one of the first plate 22 and the setting plate 14 located on the inner side) by passing through the first connecting hole 52.

[0092] like Figure 5-6 In the illustrated embodiment, the first plate 22 is located outside the cavity 11. The first plate 22 is located outside the setting plate 14. The first plate 22 is provided with a first connecting hole 52. The first connecting member 51 can be a threaded connecting member. The threaded connecting member is threadedly connected to the first connecting hole 52 and abuts against the setting plate 14. In this case, when the threaded connecting member is loosened to separate the threaded connecting member from the setting plate 14, and the first filter element 1 and the connecting seat 2 are in a detachable state, the threaded connecting member remains in the first connecting hole 52 because it is threadedly connected to the first connecting hole 52, preventing the threaded connecting member from falling off, thereby further improving the ease of disassembly and assembly of the first filter element 1.

[0093] In this case, when the first connector 51 connects the first filter 1 and the connecting seat 2, the first connector 51 can apply force to make the first filter 1 move in the opposite direction of the second direction U to the corresponding arrow until the positioning mating structure 42 abuts against the positioning structure 41, for example, the first positioning mating structure 42 abuts against the first positioning structure 41.

[0094] The first connector 51 can also be a snap-fit ​​connector, which snaps into the first connecting hole 52 and abuts against the setting plate 14. Figure 6 The diagram shows the case where the first connector 51 is a threaded connector.

[0095] In a further alternative, one of the first plate 22 and the setting plate 14 is provided with a groove 53 on its inner side, and the first connector 51 is accommodated in the groove 53 and abuts against the bottom of the groove 53.

[0096] like Figure 5-6 As shown, the plate 14 is provided with a groove 53, and the end of the first connector 51 is accommodated in the groove 53 and abuts against the bottom of the groove 53.

[0097] Thus, the groove 53 can be used to position and guide the first connector 51.

[0098] Furthermore, when the positioning mating structure 42 and the positioning structure 41 are positioned and connected, the groove 53 and the first connecting member 51 are limited and connected in the first direction W.

[0099] like Figure 6 As shown, specifically, a third limiting connection unit is formed between the groove 53 and the first connector 51. The abutting part of the third limiting connection unit is the third abutting part 613, and the abutting mating part of the third limiting connection unit is the third abutting mating part 623. The third abutting part 613 may be formed on the circumferential surface of the portion of the first connector 51 that is accommodated in the groove 53, and the third abutting mating part 623 may be located on the circumferential sidewall of the groove 53.

[0100] It should be understood that when the first plate 22 is located inside the cavity 11, the arrangement of the first connector 51 is similar, but in this case, the orientations of the positioning and mating structure 42 and the positioning structure 41 need to be interchanged, which will not be described in detail here.

[0101] like Figure 15-18 In the embodiments shown, please refer to the specific examples. Figure 16 Optionally, the locking unit 5 includes a first connector 51, and the first plate 22 and the setting plate 14, the one furthest from the cavity 11 (that is, the one of the first plate 22 and the setting plate 14 located on the outer side) is provided with a first connecting hole 52, and the one of the first plate 22 and the setting plate 14 close to the cavity 11 (that is, the one of the first plate 22 and the setting plate 14 located on the inner side) is provided with a second connecting hole 54. The first connector 51 is connected to the first connecting hole 52 and the second connecting hole 54 respectively.

[0102] like Figure 16 In the illustrated scheme, the set plate 14 does not have a groove 53, but instead has a second connecting hole 54. The first connecting member 51 is connected to the first connecting hole 52 and the second connecting hole 54 respectively. The first connecting member 51 applies a tensile force between the first plate 22 and the set plate 14. Figure 6 In the illustrated scheme, the first connector 51 applies a thrust between the first plate 22 and the set plate 14.

[0103] In this case, such as Figure 6 As shown, the first connector 51 can be configured as a threaded connector, which passes through the first connecting hole 52 and the second connecting hole 54 and is threadedly connected to the second connecting hole 54. In other scenarios, the first connector 51 can also be configured as a snap-fit ​​connector, where the snap-fit ​​connector is no longer snapped into the first connecting hole 52, but rather passes through the first connecting hole 52 and the second connecting hole 54, respectively abutting against the mutually distant end faces of the first connecting hole 52 and the second connecting hole 54.

[0104] In this case, the first connector 51 can reliably connect the first plate 22 and the set plate 14, which has a simple structure and strong practicality.

[0105] It should be understood that the thickness of the first plate 22 or the set plate 14 may be small, which may affect the connection strength of the first connector 51. Both the first plate 22 and the set plate 14 may be provided with reinforcing members 59 as needed. Figure 16 As shown, this illustrates the case where reinforcing members 59 are respectively installed at the first connecting hole 52 and the second connecting hole 54. Figure 21 As shown, this illustrates a case where a reinforcing member 59 is provided at the first connecting hole 52, and a local thickening is present at the second connecting hole 54; this is not intended to be limiting. Furthermore, if the first connecting member 51 is a threaded connection, the filter component may also be equipped with a washer 57 and a spring washer 58.

[0106] It should be understood that, in this case, the first plate 22 and the set plate 14 can be respectively provided with a positioning and mating structure 42 and a positioning structure 41. For example, as Figure 19-24 In the embodiments shown, please refer to the specific examples. Figure 23 One of the first plate 22 and the setting plate 14 is provided with a guide hole 72, and the other is provided with a guide post 71; when the guide structure 31 is accommodated in the guide mating structure 32, the guide post 71 and the guide hole 72 are connected by insertion in the second direction U; when the guide post 71 is connected by insertion with the guide hole 72, the guide post 71 and the guide hole 72 are limited by connection in the first direction W.

[0107] like Figure 23 As shown, the setting plate 14 is provided with a guide post 71, and the first plate 22 is provided with a guide hole 72. When the first connecting member 51 applies a pulling force between the setting plate 14 and the first plate 22 in the second direction U, the guide post 71 is at least partially inserted into the guide hole 72. A fourth limiting connection unit is formed between the guide post 71 and the guide hole 72. The abutting part of the fourth limiting connection unit is the fourth abutting part 614, and the abutting mating part of the fourth limiting connection unit is the fourth abutting mating part 624. For example, the fourth abutting part 614 is formed on the circumferential sidewall of the guide post 71, and the fourth abutting mating part 624 is formed on the circumferential inner wall of the guide hole 72.

[0108] Thus, the arrangement of guide post 71 and guide hole 72 can enhance the connection strength between setting plate 14 and first plate 22, and the connection reliability between first filter element 1 and connecting seat 2 is high.

[0109] like Figure 1-9 In the embodiments shown, please refer to the specific examples. Figure 2 , Figure 4As shown, optionally, the locking unit 5 further includes an elastic structure 55, in the second direction U, one of the set plate 14 and the first plate 22 is connected to the elastic structure 55, and the other of the set plate 14 and the first plate 22 abuts against the elastic structure 55.

[0110] Specifically, in the second direction U, when one of the setting plate 14 and the first plate 22 is connected to the elastic structure 55, and the other of the setting plate 14 and the first plate 22 abuts against the elastic structure 55, the elastic structure 55 acts on the setting plate 14 and the first plate 22 along the second direction U, applying a pushing force between them. Thus, the elastic structure 55 can provide a locking force for the first filter 1 and the connecting seat 2 in the second direction U, that is, it provides a force that causes the positioning mating structure 42 and the positioning structure 41 to abut against each other in the second direction U.

[0111] At this point, it should be understood that the arrangement of the elastic structure 55 can be such that the plate 14 is connected to the elastic structure 55 and the first plate 22 abuts against the elastic structure 55, or the first plate 22 is connected to the elastic structure 55 and the plate 14 abuts against the elastic structure 55. Here, the connection can be a detachable connection or a non-detachable connection.

[0112] Furthermore, one of the set plate 14 and the first plate 22 is provided with an elastic structure 55, and the other of the set plate 14 and the first plate 22 is provided with a limiting hole 56. The elastic structure 55 is partially accommodated in the limiting hole 56 and is limitedly connected to the limiting hole 56 in the first direction W.

[0113] like Figure 4 , 7 As shown, for example, the elastic structure 55 protrudes from the set plate 14. The elastic structure 55 is an arc-shaped protrusion. When the arc-shaped protrusion contacts the first plate 22, it provides a force in the second direction U. The arc-shaped protrusion and the limiting hole 56 are limited and connected in the first direction W.

[0114] Thus, the elastic structure 55 can be used to provide locking force in the second direction U, and the elastic structure 55 can also be connected with the limiting hole 56 in the second direction U to limit the force of both in the second direction U.

[0115] like Figure 19-24 In the embodiments shown, please refer to the specific examples. Figure 20 , 24 Optionally, the guide structure 31 includes a guide rail 312, and the guide mating structure 32 includes a guide groove 322. Both the guide rail 312 and the guide groove 322 extend along the second direction U, and the guide rail 312 is slidably connected to the guide groove 322.

[0116] Specifically, guide rails 312 extending along the second direction U can be provided at both ends of the first filter element 1 located in the third direction V, and correspondingly, guide grooves 322 extending along the second direction U can be provided at both ends of the connecting seat 2 located in the third direction V.

[0117] When assembling the first filter element 1 and the connecting seat 2, the positions of the guide rail 312 and the guide groove 322 are aligned, and the first filter element 1 and the connecting seat 2 move relative to each other along the second direction U. The guide rail 312 can be inserted into the guide groove 322. When the positioning mating structure 42 and the positioning structure 41 are positioned and connected, for example, when the second positioning part 412 and the second positioning mating part 422 are positioned and connected, the guide rail 312 and the guide groove 322 can be used to form a second limiting connection unit.

[0118] Specifically, the abutting part of the second limiting connection unit is the second abutting part 612, and the abutting mating part of the second limiting connection unit is the second abutting mating part 622. The second abutting part 612 can be the side wall of the guide rail 312 located in the first direction W, and the second abutting mating part 622 can be the inner wall surface of the guide groove 322 located in the first direction W. Thus, when the positioning mating structure 42 and the positioning structure 41 are positioned and connected, the guide rail 312 and the guide groove 322 are limited and connected in the first direction W.

[0119] Another embodiment of this disclosure provides a heat dissipation system that includes a filter component as described in the above embodiment.

[0120] like Figure 2 As shown, specifically, the heat dissipation system also includes a fluid drive 91, which is used to drive fluid to flow through the filter component.

[0121] Optionally, the fluid drive 91 is located at the communication port 21 of the connecting seat 2 of the filter component, and the fluid drive 91 is detachably connected to the connecting seat 2.

[0122] Specifically, the fluid drive component 91 is a fan, and the fan mounting base is located outside the communication port 21. The fan mounting base and the connecting base 2 are detachably connected.

[0123] In this way, the filter component and the fluid drive component 91 are integrated together, and the two can be installed as a whole through the connection of the connecting seat 2 to other components.

[0124] like Figure 2 As shown, optionally, the heat dissipation system further includes at least one of a second filter element 92 and a third filter element 93; the second filter element 92 is located in the cavity 11 of the first filter element 1 of the filter member, the second filter element 92 corresponds to the position of the communication port 21, and the second filter element 92 is detachably connected to the connecting seat 2; the third filter element 93 is located at the end of the fluid drive member 91 away from the first filter element 1, and the third filter element 93 is detachably connected to the fluid drive member 91.

[0125] The second filter element 92 and the third filter element 93 are both filter screens, which can protect the fluid drive component 91 to a certain extent. They have a simple structure and are highly practical.

[0126] Another embodiment of this disclosure provides an electrical device that includes the filtering component of the above embodiments, or the heat dissipation system of the above embodiments.

[0127] like Figure 25 As shown, exemplarily, the electrical equipment is an inverter, and the heat dissipation system is the ventilation and heat dissipation system of the inverter. The inverter has a main body 81, and a duct 83 and a radiator 82 are arranged on one side of the main body 81. The filter component is arranged at the inlet of the duct 83 of the ventilation and heat dissipation system, so that air flows and dissipates heat from the radiator 82 and other parts. It will not be described in detail here.

[0128] While the above disclosure is provided, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the scope of protection of this disclosure.
