[0032] The specific implementation of the present disclosure is described in detail below with reference to the accompanying drawings.

[0033] In some embodiments, the present disclosure provides a filter 100, wherein the filter 100 includes a first support plate 101 and a second support plate 102 that are relatively arranged along the height direction thereof, and a plurality of filter elements 103 arranged therebetween, 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 that are relatively arranged along the width direction thereof, and the filter elements 103 at the connecting end are abutted or tend to abut, and the filter elements 103 at the open end are away from each other and form an air inlet 107; the two filter elements 103 at the connecting end are fixed by a connecting member 104, and a filter net 105 is provided in the area between any two adjacent connecting members 104.

[0034] like Figure 1 - Figure 3 As shown, the filter 100 in this scheme 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 arranged between the first support plate 101 and the second support plate 102, wherein the plurality of filter elements 103 are arranged in a W-shape along the length direction of the filter 100. In addition, every two adjacent filter elements 103 form a group, and the two filter elements 103 in each group are arranged in a V-shape, and the two filter elements 103 arranged in a V-shape and the first support plate 101 and the second support plate 102 between the two filter elements 103 form a filter unit. In addition, the filter 100 has an open end and a connecting end arranged oppositely at both ends in the width direction, wherein the filter elements 103 at the connecting end are in contact or tend to be in contact, and the filter elements 103 at the open end are away from each other and form an air inlet 107.

[0035] In this embodiment, the two filter elements 103 that are in contact with or tend to be in contact with each other at the connection ends of the filter 100 are fixed together by a connecting piece 104, and the area between any two adjacent connecting pieces 104 is provided with a filter screen 105. It is worth noting that this embodiment does not limit the arrangement form 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 connecting pieces 104, thereby preventing mice from entering the gap between the filter units. In other embodiments, the filter screen 105 can also be as follows Figure 2 and Figure 3 The one-piece structure shown is directly covered on the outer surface of all the connecting parts 104, and can still achieve the function of preventing rats.

[0036] In this solution, since each group of filter elements 103 on the filter 100 is arranged in a V shape, there is a gap between each filter unit at the connection end. In order to prevent mice from entering the gap between the filter units and chewing the filter element 103, damaging the filter 100 and affecting the filtering effect, a filter net 105 is deliberately set between the connection ends of each filter unit, thereby intercepting mice from contacting the filter element 103 on the filter 100, thereby achieving the effect of extending the service life of the filter 100. In addition, since the filter net 105 is set on the filter 100, the operator directly applies the force to the filter net 105 when moving the filter 100, avoiding the fingers from touching the filter part, thereby preventing the operator from damaging the filter part and affecting the filtering effect of the filter 100.

[0037] like Figure 1 and Figure 2As shown, in a specific embodiment, since the filter unit is composed of the first support plate 101, the second support plate 102 and the filter element 103 arranged therebetween, and the two filter elements 103 are arranged in a V-shape, there is a hollow portion between the two filter units connected on the first support plate 101 and the second support plate 102. In order to further improve the anti-rat effect, a filter net 105 is arranged at the hollow portion of the first support plate 101 and the hollow portion of the second support plate 102. For ease of description, in this solution, the side where the open end is located is defined as the front side of the filter 100, the end where the connection end is located is defined as the rear side, the side where the first support plate 101 is located is defined as the upper side, and the side where the second support plate 102 is located is defined as the lower side. In this solution, the filter net 105 is not only arranged on the rear side of the filter 100, but also on the upper and lower sides of the filter 100, so as to more effectively prevent mice from entering the gap between the filter units and gnawing the filter element 103.

[0038] Those skilled in the art can understand that, in other embodiments, the filter 105 can also be provided only in the hollow portion of the first support plate 101 or only in the hollow portion of the second support plate 102. When in use, the end without the filter 105 is placed downward and in direct contact with the ground or other components so that the hollow portion is in a closed state, and the end with the filter 105 is placed upward. Such a setting method can still improve the rat prevention efficiency.

[0039] In a specific embodiment, the filter screen 105 at the hollow portion is fixedly connected to the first support plate 101 and the second support plate 102 .

[0040] In this solution, the filter screen 105 at the hollow portion of the first support plate 101 is fixedly connected to the first support plate 101 by injection molding or the like. In other words, the filter screen 105 at the hollow portion of the first support plate 101 is integrally formed with the first support plate 101. Similarly, the filter screen 105 at the hollow portion of the second support plate 102 is also fixedly connected to the second support plate 102 by injection molding or the like. The one-piece design in this solution simplifies the installation process, thereby reducing installation costs and time.

[0041] Of course, those skilled in the art will appreciate 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, in other embodiments, the filter screen 105 on the first support plate 101 and the second support plate 102 may also be fixedly connected together by other fixing members 108. For example, the filter screen may be detachably connected to the first support plate 101 and the second support plate 102 by fixing members.

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

[0043] In this solution, the filter screen 105 is not only arranged at the hollowed-out parts of the first support plate 101 and the second support plate 102, but also arranged on the outer surfaces of the first support plate 101 and the second support plate 102 corresponding to the filter unit. In other words, the filter screen 105 on the first support plate 101 in this solution is an integrally formed structure, which is covered on 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, and is also covered on the outer surface of the second support plate 102. Of course, in other solutions, the integrally formed filter screen 105 can be only covered on 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 side and the lower side of the filter 100 are all separately arranged. In addition to the above-mentioned arrangement, the filter screens 105 on the rear side, the upper side and the lower side of the filter 100 can also be an integrally formed structure. In a specific embodiment, the filter screens 105 on the first support plate 101 and the second support plate 102 are an integrally formed structure with the filter screens 105 covered on the connection ends of all filter units. That is to say, in this scheme, only one filter screen 105 is arranged on the filter 100, and the filter screen 105 is covered on the upper side, the rear side and the lower side of the filter 100.

[0045] In this solution, the filter screen 105 on the filter 100 is an integrally formed structure, which is not easily deformed or loosened during long-term use and has strong anti-deformation ability. In addition, the integrally formed filter screen 105 reduces the installation steps and the required tools, and there is no need to check multiple splicing points during maintenance, which reduces the installation difficulty and time cost and simplifies the maintenance process.

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

[0047] The inner surface of the filter net 105 also has a plurality of protrusions 1015 extending along the width direction of the filter 100, and the protrusions 1015 are in contact with 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 content of the above scheme, the filter screen 105 at the hollow part of the first support plate 101 is injection molded together with the first support plate 101, and the filter screen 105 at the hollow part of the second support plate 102 is also injection molded together with the second support plate 102. In this scheme, 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 provided at a position of the filter screen 105 close to the rear side of the filter 100. Specifically, the support portion 1014 is a plate-like member extending along the height direction of the filter 100, and the plate-like member can provide support force for the filter screen 105 at the rear side of the filter 100, and can effectively prevent the filter screen 105 from being greatly deformed when a mouse or other external force exerts a force on the filter screen 105, thereby protecting the integrity of the filter screen 105.

[0049] In order to better fix the support portion 1014 on 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 protrusion 1015 is a plate-like structure having a preset thickness and extending along the width direction of the filter 100, one end of which in the length direction is connected to the support portion 1014, and the other end extends toward the open end of the filter 100.

[0050] It is worth noting that, since the hollow portions on the first support plate 101 and the second support plate 102 in this solution are arranged at intervals, the support portions 1014 are also arranged at intervals on the first support plate 101 and the second support plate 102 .

[0051] Those skilled in the art can understand that the support portion 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 portion 1014 is also correspondingly only arranged on the first support plate 101 or the second support plate 102.

[0052] The above scheme introduces in detail the arrangement of the filter screen 105 on the filter 100 , and the specific structure of the connector 104 and how the connector 104 connects the two filter elements 103 together are introduced in detail below.

[0053] like Figure 3 , Figure 6 and Figure 7As shown, in a specific embodiment, the filter element 103 is a square plate-shaped member with a preset thickness, which has two side walls arranged opposite to each other in the length direction of the filter 100, and two end walls arranged respectively towards the open end and the connecting end; the connecting member 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 angle between the extended surfaces of the first connecting plate 1041 and the third connecting plate 1043 is the same as the 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 side walls of the two filter elements 103, and the second connecting plate 1042 limits the end wall of the filter element 103 facing the connecting end.

[0054] In this solution, the inner surface of the first support plate 101 has a mounting groove formed by a plurality of ribs 1011 protruding from the inner surface thereof, and correspondingly, the inner surface of the second support plate 102 also has a mounting groove formed by a plurality of ribs 1011, wherein the size and number of the mounting grooves match the number and size of the filter element 103. In addition, the filter element 103 on the filter 100 of this solution is a square plate-shaped member with a preset thickness, which has not only two side walls and two end walls, but also two top walls respectively facing the first support plate 101 and the second support plate 102. When the filter element 103 is in an assembled state, the two top walls are respectively limited in 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 solution is in the shape of a groove, 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 angle between the first connecting plate 1041 and the second connecting plate 1042 is an obtuse angle, and the angle between the third connecting plate 1043 and the second connecting plate 1042 is also an obtuse angle. In addition, in this solution, the angle between the extended surfaces of the first connecting plate 1041 and the third connecting plate 1043 is the same as the angle between the two filter elements 103 connected at the connecting end.

[0056] When the connector and the filter element are in an assembled state, the first connecting plate 1041 and the third connecting plate 1043 abut against and limit the two side walls of the two filter elements 103 that are away from each other, and the second connecting plate 1042 abuts against and limits the end walls of the two filter elements 103 that are facing the connection end. In other words, 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 can understand that, in order to better fix the filter element 103, glue can be injected into the installation groove and the connecting piece 104 to make the connection between the filter element 103 and the installation groove and the connecting piece 104 more firmly.

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

[0059] In this solution, the two filter elements 103 at the connection end are not in contact with each other, and there is a gap between them. At the same time, a limiting member 1044 is also provided on the connector 104 in this solution. Specifically, the limiting member 1044 is provided on the inner surface of the second connecting plate 1042, and it 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 two filter elements 103 respectively. In this solution, the connection strength between the filter element 103 and the connector 104 is enhanced by the cooperation of the limiting member 1044 and the gap, effectively preventing the filter element 103 from displacement or shaking at the connection end, and ensuring that the filter element 103 remains stable during use.

[0060] In a specific embodiment, the stopper 1044 divides the first connecting plate 1041 into two parts, and the angle between the two parts and the stopper 1044 is an obtuse angle greater than 90 degrees, wherein the obtuse angle can be 90.5 degrees, or 91 degrees or other degrees. In other words, the two parts of the first connecting plate 1041 are slightly extended outward. This arrangement enables the glue on the connecting member 104 to quickly pass through the inner surface of the first connecting member 104, reducing the glue creeping on the surface of the filter element 103, reducing the amount of glue used, and reducing production costs.

[0061] like Figure 3 As shown, in a specific embodiment, two adjacent filter elements 103 at the open ends are fixed by a connecting piece 104 .

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

[0063] like Figure 3 and Figure 5 As shown, in a specific embodiment, the inner side wall of the rib 1011 facing the installation groove has a blocking portion 1012 extending in the length direction of the filter 100 for limiting the first connecting plate 1041 and the third connecting plate 1043 .

[0064] In this embodiment, at least one set of blocking parts 1012 is arranged opposite to each other on the two convex ribs 1011 constituting a mounting groove, and the blocking parts 1012 are respectively used to limit the first connecting plate 1041 and the third connecting plate 1043 on the connecting member 104. Specifically, the two blocking parts 1012 are plate-like structures or protrusions extending in the length direction of the filter 100. When the filter element 103 and the connecting member 104 are both assembled between the first support plate 101 and the second support plate 102, one blocking part 1012 abuts against and limits the end of the first connecting plate 1041 away from the second connecting plate 1042, and the other blocking part 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 grooves are connected to each other, and the connection has an extension portion 1013 extending toward the open end and the connection end; the end of the second connecting plate 1042 in the length direction is provided with a fixing portion 1045 adapted to the extension portion 1013, and the extension portion 1013 is inserted into the fixing portion 1045 to limit the connecting member 104.

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

[0067] In this solution, the filter element 103 is arranged in a W shape along the length direction of the filter 100, and accordingly, 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 direction of the filter 100. It can be understood by those skilled in the art that one mounting groove is formed by two convex ribs 1011, and two mounting grooves are formed by four convex ribs 1011. In this solution, among the four convex ribs 1011 constituting two adjacent mounting grooves, the ends of the two adjacent convex ribs 1011 are connected to each other. The convex rib 1011 has two extensions 1013 extending toward the open end and the connection end respectively at the connection of the two ends in the width direction of the filter 100. At the same time, the end of the second connecting plate 1042 in the length direction is provided with a fixing portion 1045 adapted to the extension portion 1013. Specifically, the fixing portion 1045 is a semi-cylindrical groove arranged on the inner surface of the second connecting plate 1042, wherein one end of the groove abuts against the limiting portion, and the other end extends toward the open end or the connection end of the filter 100. During installation, the extension portion 1013 is inserted into the fixing portion 1045 , thereby better limiting the position of the connector 104 in the installation slot.

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

[0069] In this solution, the second connecting plate 1042 is provided with a collecting groove 1046 at the end close to the first support plate 101 and the second support plate 102, and the opening of the collecting groove 1046 faces the first support plate 101 or the second support plate 102 close thereto. In other words, two mounting grooves are provided at the two ends in the height direction of the second connecting plate 1042, and the openings of the mounting grooves face the first support plate 101 and the second support plate 102 close thereto. It can be understood by those skilled in the art that, in order to more firmly fix the filter element 103 to the connecting member 104, glue will be coated on the inner surface of the connecting member 104, and in order to avoid glue leakage after gluing, increase the workload, or affect the appearance of the product, a collecting groove 1046 is further provided at the end of the connecting member 104 to collect and hold the overflowed glue.

[0070] Those skilled in the art may understand that, in other solutions, only one collecting groove 1046 may be provided on the second connecting plate 1042 , and the collecting groove 1046 may be provided at an end close to the first support plate 101 or at an end close to the second support plate 102 .

[0071] In a specific embodiment, a protruding positioning portion 1047 is added to the outer surface of the collecting groove 1046, so that the extension portion 1013 can be more accurately positioned to the fixing portion 1045, making it easier to assemble the two and reducing the labor intensity of personnel.

[0072] The above solution introduces the specific structure of the connecting member 104 in detail, and the following describes in detail how the filter screen 105 is installed on the filter 100.

[0073] like Figure 2 As shown, in a specific embodiment, a pressure plate 106 is provided on the filter 100, and a plurality of fixing holes are arranged at intervals along the height direction of the pressure plate 106; the second connecting plate 1042 has assembly holes arranged corresponding to the fixing holes on the outer surface away from the filter element 103; the fasteners fix the filter screen 105 on 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 solution, the filter screen 105 is fixed to the connector 104 through the pressing plate 106. Specifically, the outer surface of the second connecting plate 1042 of the connector 104 has a plurality of assembly holes arranged at intervals along its height direction, and the pressing plate 106 has fixing holes arranged corresponding to the assembly holes. During installation, fasteners such as screws and bolts pass through the fixing holes on the pressing plate 106, the filter screen 105 and the assembly holes on the connector 104 in sequence to fix the filter screen 105 on the connector 104. In this solution, the filter screen 105 is fixed to the connector 104 through the pressing plate 106, thereby increasing the fixing area of ​​the filter screen 105 and avoiding damage to the filter screen 105 due to its own gravity and other reasons.

[0075] In a specific embodiment, in order 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 a plurality of reinforcing ribs extending along the height direction of the filter 100, but also a plurality of reinforcing ribs extending along the length direction of the filter 100. In other words, the connector 104 in this solution has not only vertically arranged reinforcing ribs, but also transversely arranged reinforcing ribs. The transverse reinforcing ribs are combined with the vertical reinforcing ribs to form a mesh-like reinforcement structure, which further improves the overall rigidity of the middle strip, so that it can remain stable under various working conditions.

[0076] Those skilled in the art will appreciate that the present solution does not specifically limit the arrangement form and number of the reinforcing ribs. That is, in other embodiments, only transverse reinforcing ribs or only vertical reinforcing ribs may be arranged on the connecting member 104. As for the number of reinforcing ribs, it may be four, six, or any other positive integer.

[0077] like Figure 1 and Figure 2 As shown, in a specific embodiment, fixing members 108 are provided at two ends of the filter 100 in the length direction.

[0078] In this solution, in order to limit the filter element 103 at both ends in the length direction of the filter 100, a fixing member 108 is respectively provided on the outermost sides of the two filter elements 103. Specifically, both ends in the height direction of the fixing member 108 are respectively fixed on 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 in the height direction of the fixing member 108 have a groove in the middle, and the positioning member is inserted into the groove to limit the fixing member 108.

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