[0032] The specific embodiments disclosed herein will now be described in detail with reference to the accompanying drawings.

[0033] In some embodiments, this disclosure provides a filter 100, the filter 100 including a first support plate 101 and a second support plate 102 disposed opposite each other along its height direction, and a plurality of filter elements 103 disposed between the two, wherein the plurality of filter elements 103 are arranged in a W-shape along the length direction of the filter 100; the filter 100 includes an open end and a connecting end disposed opposite each other along its width direction, and the filter elements 103 at the connecting end abut or tend to abut each other, the filter elements 103 at the open end are far apart from each other and form an air inlet 107; the two filter elements 103 at the connecting end are fixed by a connector 104, and a filter screen 105 is provided in the area between any two adjacent connectors 104.

[0034] like Figure 1 - Figure 3 As shown, the filter 100 in this solution mainly includes a main frame composed of a first support plate 101 and a second support plate 102, and a plurality of filter elements 103 for filtering air disposed between the first support plate 101 and the second support plate 102. The filter elements 103 are arranged in a W-shape along the length of the filter 100. Furthermore, each pair of adjacent filter elements 103 forms a group, and the two filter elements 103 in each group are arranged in a V-shape. The two V-shaped filter elements 103 and the first support plate 101 and the second support plate 102 between the two filter elements 103 form a filtration unit. Additionally, the filter 100 has open ends and connecting ends disposed opposite each other at both ends in its width direction. The filter elements 103 at the connecting ends abut or tend to abut each other, while the filter elements 103 at the open ends are spaced apart and form an air inlet 107.

[0035] In this design, the two filter elements 103 at the connection ends of the filter 100, which are either abutting or nearly abutting each other, are fixed together by connectors 104, and a filter screen 105 is provided in the area between any two adjacent connectors 104. It is worth noting that this design does not limit the arrangement of the filter screen 105 between the connection ends. For example, in one embodiment, the two ends of the filter screen 105 can be connected to two adjacent connectors 104, thereby preventing mice from entering the gap between the filter units. In other designs, the filter screen 105 can also be as follows... Figure 2 and Figure 3 The one-piece molded structure shown is directly covered on the outer surface of all connectors 104, and it can still achieve the function of rodent prevention.

[0036] In this design, since each filter element 103 on the filter 100 is V-shaped, there are gaps between the filter units at the connection ends. To prevent mice from entering these gaps and gnawing on the filter elements 103, thus damaging the filter 100 and affecting its filtration efficiency, a filter screen 105 is specifically installed between the connection ends of each filter unit. This effectively prevents mice from contacting the filter elements 103 on the filter 100, thereby extending the service life of the filter 100. Furthermore, because the filter screen 105 is installed on the filter 100, when the operator moves the filter 100, the force is applied directly to the filter screen 105, avoiding finger contact with the filter part and preventing damage to the filter part, which would affect the filtration efficiency of the filter 100.

[0037] like Figure 1 and Figure 2As shown, in a specific embodiment, the filter unit is composed of a first support plate 101, a second support plate 102, and a filter element 103 disposed between them, with the two filter elements 103 arranged in a V-shape. Therefore, there is a perforated portion between the two filter units connected on the first support plate 101 and the second support plate 102. To further improve the rodent-proof effect, filter screens 105 are provided at the perforated portions of the first support plate 101 and the second support plate 102. For ease of description, in this embodiment, the side with the open end is defined as the front side of the filter 100, the end with the connecting end is defined as the rear side, the side with the first support plate 101 is defined as the upper side, and the side with the second support plate 102 is defined as the lower side. In this embodiment, filter screens 105 are not only provided on the rear side of the filter 100, but also on the upper and lower sides of the filter 100, thereby more effectively preventing mice from entering the gaps between the filter units and gnawing on the filter element 103.

[0038] Those skilled in the art will understand that in other embodiments, the filter 105 may be provided only in the perforated portion on the first support plate 101 or only in the perforated portion on the second support plate 102. In use, the end without the filter 105 is placed downwards and in direct contact with the ground or other components, thus keeping the perforated portion closed, while the end with the filter 105 is placed upwards. This arrangement still improves rodent-proof efficiency.

[0039] In one specific implementation, the filter screen 105 at the hollowed-out portion is fixedly connected to the first support plate 101 and the second support plate 102.

[0040] In this design, the filter screen 105 at the hollowed-out portion of the first support plate 101 is fixedly connected to the first support plate 101 by injection molding or other methods. That is, the filter screen 105 at the hollowed-out portion of the first support plate 101 is integrally formed with the first support plate 101. Similarly, the filter screen 105 at the hollowed-out portion of the second support plate 102 is also fixedly connected to the second support plate 102 by injection molding or other methods. This integrally formed design simplifies the installation process, thereby reducing installation costs and time.

[0041] Of course, those skilled in the art will understand that this solution does not limit the connection method between the filter screen 105 and the first support plate 101 and the second support plate 102. That is to say, in other embodiments, the filter screen 105 on the first support plate 101 and the second support plate 102 can also be fixedly connected together by other fasteners 108. For example, the filter screen can be detachably connected to the first support plate 101 and the second support plate 102 by fasteners.

[0042] In one specific implementation, the outer surface of the first support plate 101 and / or the second support plate 102 is covered with a filter screen 105, which covers the hollow portion.

[0043] In this design, the filter screen 105 is not only located at the perforated portions of the first support plate 101 and the second support plate 102, but also on the outer surfaces of the corresponding support plates 101 and 102. That is, the filter screen 105 on the first support plate 101 is an integrally formed structure, covering the outer surface of the first support plate 101. The filter screen 105 on the second support plate 102 is also an integrally formed structure, covering the outer surface of the second support plate 102. Of course, in other designs, the integrally formed filter screen 105 may only cover the first support plate 101 or the second support plate 102.

[0044] In the above scheme, the filter screen 105 on the rear side of the filter 100, and the filter screens 105 on the upper and lower sides of the filter 100 are all separately arranged. Besides the above arrangement, the filter screens 105 on the rear, upper, and lower sides of the filter 100 can also be a single-piece structure. In a specific embodiment, the filter screens 105 on the first support plate 101 and the second support plate 102 are a single-piece structure with the filter screens 105 covering the connection ends of all filter units. That is, in this scheme, only one filter screen 105 is provided on the filter 100, and this filter screen 105 covers the upper, rear, and lower sides of the filter 100.

[0045] In this design, the filter screen 105 on the filter 100 is a one-piece molded structure. This structure is not easily deformed or loosened during long-term use and has strong resistance to deformation. In addition, the one-piece molded filter screen 105 reduces installation steps and required tools, and maintenance does not require checking multiple splicing points, reducing installation difficulty and time costs, and simplifying the maintenance process.

[0046] like Figure 3 and Figure 4 As shown, in some embodiments, the filter screen 105 on the first support plate 101 and / or the second support plate 102 is provided with a plurality of support portions 1014 on its inner surface near the connection end, and the support portions 1014 are plate-shaped members extending along the height direction of the filter 100.

[0047] The inner surface of the filter screen 105 also has a plurality of protrusions 1015 extending along the width direction of the filter 100, and the protrusions 1015 abut against the support portion 1014; wherein the extension direction of a plurality of filter units is the length direction of the filter 100, and the width direction is perpendicular to both the length direction and the height direction.

[0048] Following the above solution, the filter screen 105 at the hollowed-out portion of the first support plate 101 is injection molded to the first support plate 101, and the filter screen 105 at the hollowed-out portion of the second support plate 102 is also injection molded to the second support plate 102. In this solution, a support portion 1014 is provided on the inner surface of the filter screen 105 on the first support plate 101 and the second support plate 102, wherein the support portion 1014 is located near the rear side of the filter 100. Specifically, the support portion 1014 is a plate-shaped member extending along the height direction of the filter 100. This plate-shaped member can provide support for the filter screen 105 at the rear side of the filter 100, effectively preventing large deformation of the filter screen 105 when mice or other external forces apply force to it, thereby protecting the integrity of the filter screen 105.

[0049] In order to better fix the support 1014 to the filter screen 105, in one embodiment, the inner surface of the filter screen 105 on the first support plate 101 and the second support plate 102 has a plurality of spaced protrusions 1015, wherein the protrusions 1015 are plate-shaped structures with a preset thickness and extending along the width direction of the filter 100, one end of which is connected to the support 1014 in the length direction, and the other end extends toward the open end of the filter 100.

[0050] It is worth noting that, since the hollowed-out portions on the first support plate 101 and the second support plate 102 in this solution are spaced apart, the support portion 1014 is also spaced apart on the first support plate 101 and the second support plate 102.

[0051] Those skilled in the art will understand that the support 1014 and the filter 105 are arranged synchronously. That is, when the filter 105 is only arranged on the first support plate 101 or the second support plate 102, the support 1014 is also correspondingly only arranged on the first support plate 101 or the second support plate 102.

[0052] The above scheme details the arrangement of the filter screen 105 on the filter 100. Next, the specific structure of the connector 104 and how the connector 104 connects the two filter elements 103 together will be described in detail.

[0053] like Figure 3 , Figure 6 and Figure 7As shown, in a specific embodiment, the filter element 103 is a square plate-shaped piece with a preset thickness, having two sidewalls arranged opposite each other along the length direction of the filter 100, and two endwalls respectively facing the open end and the connecting end; the connector 104 includes a first connecting plate 1041, a second connecting plate 1042, and a third connecting plate 1043 connected in sequence, wherein the first connecting plate 1041 and the third connecting plate 1043 are symmetrically arranged, and the included angle between the extended surfaces of the first connecting plate 1041 and the third connecting plate 1043 is the same as the included angle between the two filter elements 103 connected at the connecting end; the first connecting plate 1041 and the third connecting plate 1043 limit the sidewalls of the two filter elements 103, and the second connecting plate 1042 limits the endwall of the filter element 103 facing the connecting end.

[0054] In this design, the inner surface of the first support plate 101 has mounting grooves formed by a plurality of protruding ribs 1011. Correspondingly, the inner surface of the second support plate 102 also has mounting grooves formed by a plurality of protruding ribs 1011. The size and number of mounting grooves are matched with the number and size of the filter elements 103. Furthermore, the filter elements 103 on the filter 100 in this design are square plate-shaped pieces with a preset thickness. They have two side walls and two end walls, as well as two top walls facing the first support plate 101 and the second support plate 102 respectively. When the filter element 103 is in the assembled state, the two top walls are respectively confined within the mounting grooves on the first support plate 101 and the second support plate 102.

[0055] like Figure 6 and Figure 7 As shown, the connector 104 in this design is groove-shaped and includes a first connecting plate 1041, a second connecting plate 1042, and a third connecting plate 1043 connected in sequence, wherein the first connecting plate 1041 and the third connecting plate 1043 are symmetrically arranged. The included angle between the first connecting plate 1041 and the second connecting plate 1042 is an obtuse angle, and the included angle between the third connecting plate 1043 and the second connecting plate 1042 is also an obtuse angle. In addition, in this design, the included angle between the extended surfaces of the first connecting plate 1041 and the third connecting plate 1043 is the same as the included angle between the two filter elements 103 connected at the connection end.

[0056] When the connector and filter element are assembled, the first connecting plate 1041 and the third connecting plate 1043 abut against and limit the two mutually distant side walls of the two filter elements 103, and the second connecting plate 1042 abuts against and limits the end walls of the two filter elements 103 facing the connection end. That is, the first connecting plate 1041 and the third connecting plate 1043 of the connector 104 limit the filter element 103 in the length direction of the filter 100, and the second connecting plate 1042 limits the filter element 103 in the width direction of the filter 100. The mounting grooves on the first support plate 101 and the second support plate 102 limit the filter element 103 in the height direction of the filter 100.

[0057] Those skilled in the art will understand that, in order to better fix the filter element 103, adhesive can be injected into the mounting groove and the connector 104 to make the connection between the filter element 103 and the mounting groove and the connector 104 more secure.

[0058] In one specific implementation, there is a gap between two filter elements 103 connected by the connector 104 at the connection end; the inner surface of the second connecting plate 1042 has a protruding limiting member 1044, which is inserted into the gap to limit the filter element 103.

[0059] In this design, the two filter elements 103 at the connection end are not in contact with each other; there is a gap between them. Meanwhile, a limiting member 1044 is also provided on the connector 104. Specifically, the limiting member 1044 protrudes from the inner surface of the second connecting plate 1042 and has a certain extension height. It is worth noting that the inner surface of the second connecting plate 1042 refers to the side of the second connecting plate 1042 facing the open end of the filter 100, and the height direction of the limiting member 1044 is the height direction of the filter 100. When the filter element 103 is connected to the connector 104, the limiting member 1044 is inserted into the gap between the two filter elements 103 and limits the movement of each filter element 103. In this design, the cooperation between the limiting member 1044 and the gap enhances the connection strength between the filter element 103 and the connector 104, effectively preventing displacement or shaking of the filter element 103 at the connection end and ensuring the stability of the filter element 103 during use.

[0060] In one specific implementation, the limiting member 1044 divides the first connecting plate 1041 into two parts. The angle between these two parts and the limiting member 1044 is an obtuse angle greater than 90 degrees, where the obtuse angle can be 90.5 degrees, 91 degrees, or other degrees. That is, the two parts of the first connecting plate 1041 extend slightly outward. This arrangement allows the adhesive on the connector 104 to quickly pass through the inner surface of the first connector 104, reducing adhesive creep on the surface of the filter element 103, reducing adhesive usage, and lowering production costs.

[0061] like Figure 3 As shown, in one specific embodiment, two adjacent filter elements 103 at the open end are fixed together by a connector 104.

[0062] In this solution, not only are the ends of two adjacent filter elements 103 connected by a connector 104 at the connection end, but two adjacent filter elements 103 at the open end are also connected and fixed by a connector 104.

[0063] like Figure 3 and Figure 5 As shown, in a specific embodiment, the rib 1011 has a blocking portion 1012 extending toward the length direction of the filter 100 on the inner sidewall of the mounting groove, which is used to limit the first connecting plate 1041 and the third connecting plate 1043.

[0064] In this design, the two protruding ribs 1011 forming a mounting groove have at least one set of opposing blocking portions 1012. The blocking portions 1012 are used to limit the first connecting plate 1041 and the third connecting plate 1043 on the connector 104. Specifically, the two blocking portions 1012 are plate-like structures or protrusions extending along the length of the filter 100. When the filter element 103 and the connector 104 are both assembled between the first support plate 101 and the second support plate 102, one blocking portion 1012 abuts against and limits the end of the first connecting plate 1041 away from the second connecting plate 1042, and the other blocking portion 1012 abuts against and limits the end of the third connecting plate 1043 away from the second connecting plate 1042.

[0065] like Figure 5 - Figure 7 As shown, in a specific embodiment, the ends of two adjacent ribs 1011 in two adjacent mounting slots are connected to each other, and the connection has an extension 1013 extending towards the open end and the connection end; the end of the second connecting plate 1042 in the length direction is provided with a fixing part 1045 adapted to the extension 1013, and the extension 1013 is inserted into the fixing part 1045 to limit the connection member 104.

[0066] Specifically, the fixing part 1045 is a semi-cylindrical groove provided on the second connecting plate 1042; the fixing part 1045 is connected to the limiting member 1044, and its extension direction is the same as the extension direction of the limiting member 1044.

[0067] In this design, the filter element 103 is arranged in a W-shape along the length of the filter 100. Correspondingly, the mounting grooves on the first support plate 101 and the second support plate 102 are also arranged in a W-shape along the length of the filter 100. Those skilled in the art will understand that one mounting groove is formed by two ribs 1011, and two mounting grooves are formed by four ribs 1011. In this design, the ends of the four ribs 1011 constituting two adjacent mounting grooves are connected to each other. The ribs 1011 have two extensions 1013 at the connection point of their two ends in the width direction of the filter 100, extending towards the open end and the connecting end, respectively. Meanwhile, the end of the second connecting plate 1042 in the length direction is provided with a fixing part 1045 adapted to the extension 1013. Specifically, the fixing part 1045 is a semi-cylindrical groove provided on the inner surface of the second connecting plate 1042, wherein one end of the groove abuts against the limiting part, and the other end extends towards the open end or the connecting end of the filter 100. During installation, the extension 1013 is inserted into the fixing part 1045, thereby better positioning the connector 104 in the mounting groove.

[0068] like Figure 6 As shown, in a specific embodiment, a collection groove 1046 is provided at the end of the second connecting plate 1042 near the first support plate 101 and / or the second support plate 102, and the opening of the collection groove 1046 faces the first support plate 101 and / or the second support plate 102 that are close to it.

[0069] In this design, the second connecting plate 1042 has a collection groove 1046 at its end near the first support plate 101 and the second support plate 102. The opening of the collection groove 1046 faces the first support plate 101 or the second support plate 102 adjacent to it. That is, two mounting grooves are provided at the two ends of the second connecting plate 1042 in the height direction, and the openings of the mounting grooves face the first support plate 101 and the second support plate 102 adjacent to them. Those skilled in the art will understand that in order to more firmly fix the filter element 103 to the connector 104, glue is applied to the inner surface of the connector 104. To avoid glue leakage after application, which would increase workload or affect the appearance of the product, a collection groove 1046 is provided at the end of the connector 104 to collect and hold the overflowing glue.

[0070] Those skilled in the art will understand that in other solutions, the second connecting plate 1042 may be provided with only one collection groove 1046, and the collection groove 1046 may be provided at the end near the first support plate 101 or at the end near the second support plate 102.

[0071] In one specific implementation, a protruding positioning part 1047 is added to the outer surface of the collection tank 1046, which enables the extension part 1013 to be more accurately positioned to the fixing part 1045, making it easier to assemble the two and reducing the labor intensity of personnel.

[0072] The above scheme details the specific structure of connector 104. Next, we will describe in detail how filter screen 105 is installed on filter 100.

[0073] like Figure 2 As shown, in a specific embodiment, the filter 100 is provided with a pressure plate 106, and has a plurality of spaced fixing holes along the height direction of the pressure plate 106; the second connecting plate 1042 has assembly holes corresponding to the fixing holes on its outer surface away from the filter element 103; the fastener fixes the filter screen 105 to the connecting member 104 by passing through the fixing holes on the pressure plate 106, the filter screen 105 and the assembly holes on the connecting member 104 in sequence.

[0074] In this design, the filter screen 105 is fixed to the connector 104 by a pressure plate 106. Specifically, the outer surface of the second connecting plate 1042 of the connector 104 has several mounting holes spaced apart along its height direction, and the pressure plate 106 has fixing holes corresponding to the mounting holes. During installation, fasteners such as screws and bolts pass through the fixing holes on the pressure plate 106, the filter screen 105, and the mounting holes on the connector 104 in sequence to fix the filter screen 105 to the connector 104. In this design, the filter screen 105 is fixed to the connector 104 by the pressure plate 106, thereby increasing the fixing area of ​​the filter screen 105 and preventing damage to the filter screen 105 due to its own weight or other reasons.

[0075] In one specific implementation, to improve the support strength and service life of the connector 104, reinforcing ribs are provided on the connector 104. Specifically, the outer surface of the second connecting plate 1042 has not only several reinforcing ribs extending along the height direction of the filter 100, but also several reinforcing ribs extending along the length direction of the filter 100. That is to say, the connector 104 in this solution has not only vertically arranged reinforcing ribs, but also horizontally arranged reinforcing ribs. The combination of horizontal and vertical reinforcing ribs forms a mesh-like reinforcing structure, further improving the overall rigidity of the intermediate strip and ensuring its stability under various working conditions.

[0076] Those skilled in the art will understand that this solution does not impose specific limitations on the form or number of reinforcing ribs. That is, in other embodiments, the connector 104 may only have transverse reinforcing ribs or only vertical reinforcing ribs. As for the number of reinforcing ribs, it can be four, six, or other positive integers.

[0077] like Figure 1 and Figure 2 As shown, in one specific embodiment, fasteners 108 are provided at both ends of the filter 100 along its length.

[0078] In this design, to limit the filter elements 103 at both ends along the length of the filter 100, a fixing member 108 is provided on the outermost side of each of the two filter elements 103. Specifically, the two ends of the fixing member 108 along the height direction are respectively fixed to the first support plate 101 and the second support plate 102. More specifically, the inner surfaces of the first support plate 101 and the second support plate 102 have protruding positioning members, and the two ends of the fixing member 108 along the height direction have grooves in the middle, into which the positioning members are inserted to limit the fixing member 108.

[0079] It is worth noting that in this scheme, the length direction of filter 100 refers to the extension direction of several filter units, the height of filter 100 refers to the extension direction between the first support plate 101 and the second support plate 102, and the width direction of filter 100 refers to the extension direction between the open end and the connecting end.

[0080] While numerous embodiments of this disclosure have been shown and described herein, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Many modifications, alterations, and alternatives will occur to those skilled in the art without departing from the spirit and intent of this disclosure. It should be understood that various alternatives to the embodiments of this disclosure described herein may be employed in the practice of this disclosure. The appended claims are intended to define the scope of this disclosure and therefore cover equivalents or alternatives within the scope of these claims.
