Similarly, the phrase "if determined" or "if [described condition or event] is detected" may be interpreted, depending on the context, as "once determined," "in response to determination," "once [described condition or event] is detected," or "in response to detection of [described condition or event]."

[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 plurality of V-shaped filter units arranged sequentially along its length, the filter unit including an open end and a connecting end disposed opposite to the open end, wherein the open end has an air inlet 107, and a filter screen 105 is disposed in the area between any two adjacent connecting ends.

[0034] like Figure 1 - Figure 3As shown, the filter 100 in the present solution comprises a plurality of V-shaped filter units connected in sequence, which are arranged in sequence along the length direction of the filter 100, wherein each filter unit is provided with a filter part for filtering air. Specifically, each filter unit is provided with an open end and a connecting end, and the open end and the connecting end are arranged opposite along the width direction of the filter 100. The open end is provided with an air inlet 107, and air enters the inside of the breeding farm after being filtered by the filter part. More specifically, between the connecting ends of any two adjacent filter units, a filter screen 105 is installed. That is, the filter unit in the present solution is V-shaped, so there is a gap between each filter unit on the side opposite to the open end. In order to prevent mice from entering the gap between the filter units and gnawing the filter part, damaging the filter 100 and affecting the filtering effect, the filter screen 105 is specially arranged between the connecting ends of each filter unit, so as to intercept the mice from contacting the filter part on the filter 100, thereby prolonging the service life of the filter 100. In addition, since the filter screen 105 is arranged on the filter 100, the operator directly applies force to the filter screen 105 when moving the filter 100, avoiding the fingers touching the filter part, thereby preventing the operator from damaging the filter part and affecting the filtering effect of the filter 100.

[0035] In the present solution, the form of the filter screen 105 arranged between the connecting ends is not limited. For example, in one embodiment, the connecting end of the filter unit is provided with a connecting piece 104 connected to the filter part, and the two ends of the filter screen 105 can be connected to two adjacent connecting pieces 104 respectively, thereby preventing mice from entering the gap between the filter units.

[0036] As shown in Figure 1 and Figure 2 In a specific embodiment, the filter 100 comprises a first support plate 101 and a second support plate 102 arranged opposite along the height direction thereof, and a plurality of filter cores 103 arranged between the two support plates; two adjacent filter cores 103 are arranged in a V shape, one end of which abuts or tends to abut, and the other end of which is away from each other and forms an open end; the first support plate 101 and the second support plate 102 between two adjacent filter units form a filter unit; the first support plate 101 and the second support plate 102 between two adjacent filter units are provided with a plurality of spaced hollow parts, and the hollow parts of the first support plate 101 and / or the second support plate 102 are provided with a filter screen 105.

[0037] In the present scheme, the filter 100 mainly comprises a main frame composed of a first support plate 101 and a second support plate 102, and a plurality of filter elements 103 arranged between the first support plate 101 and the second support plate 102. The filter element 103 refers to the filter part mentioned in the above scheme, which is used for filtering air. 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. That is, one end of the two filter elements 103 abuts or tends to abut each other to form a connecting end, and the other end is away from each other to form an open end. The open end is provided with an air inlet 107, through which air enters the inside of the filter 100 for filtering. It is worth noting that one filter unit in the present scheme is a structural unit surrounded by a group of filter elements 103 and the first support plate 101 and the second support plate 102.

[0038] In the present scheme, since the filter unit is composed of the first support plate 101 and the second support plate 102 and the filter elements 103 arranged therebetween, and the two filter elements 103 are arranged in a V shape, the first support plate 101 and the second support plate 102 have a hollow part between the two filter units connected thereon. In order to further improve the rat prevention effect, a filter screen 105 is arranged at the hollow part of the first support plate 101 and the hollow part of the second support plate 102. For the convenience of description, in the present scheme, the side where the open end is located is defined as the front side of the filter 100, the side where the connecting 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 the present scheme, not only is the filter screen 105 arranged on the rear side of the filter 100, but also the filter screen 105 is arranged on the upper side and the lower side of the filter 100, so that the rat is more effectively prevented from entering the gap between the filter units and gnawing the filter elements 103.

[0039] Those skilled in the art can understand that in other embodiments, the filter screen 105 can also be arranged only at the hollow part on the first support plate 101 or only at the hollow part on the second support plate 102. When in use, the end without the filter screen 105 is placed downward and directly contacts the ground or other components, so that the hollow part is in a closed state, and the end with the filter screen 105 is placed upward. This arrangement can still improve the rat prevention efficiency.

[0040] In a specific embodiment, the filter screen 105 at the hollow part is fixedly connected with the first support plate 101 and the second support plate 102.

[0041] In the present scheme, the filter screen 105 at the hollowed part on the first support plate 101 is fixedly connected on the first support plate 101 by injection molding or the like. That is, the filter screen 105 at the hollowed part of the first support plate 101 is integrally formed with the first support plate 101. Similarly, the filter screen 105 at the hollowed part of the second support plate 102 is also fixedly connected on the second support plate 102 by injection molding or the like. The integrally formed design in the present scheme simplifies the installation process, thereby reducing the installation cost and time.

[0042] Of course, those skilled in the art can understand that the present scheme does not limit the connection mode of the filter screen 105 with 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 can also be fixedly connected together by other fixing members 108. For example, the filter screen can be detachably connected to the first support plate 101 and the second support plate 102 by the fixing members.

[0043] 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 screen 105, which covers the hollowed part.

[0044] In the present scheme, the filter screen 105 is not only provided at the hollowed part of the first support plate 101 and the second support plate 102, but also provided on the outer surface of the first support plate 101 and the second support plate 102 corresponding to the filter unit. That is, the filter screen 105 on the first support plate 101 in the present scheme is an integrally formed structure, which covers 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, which covers the outer surface of the second support plate 102. Of course, in other schemes, the integrally formed filter screen 105 can only cover the first support plate 101 or the second support plate 102.

[0045] In the above scheme, the filter screen 105 at the rear side of the filter 100, the filter screen 105 at the upper side and the lower side of the filter 100 are separately provided. In addition to the above-mentioned arrangement, the filter screen 105 at 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 screen 105 on the first support plate 101 and the second support plate 102 is an integrally formed structure with the filter screen 105 covering the connection end of all filter units. That is, in the present scheme, only one filter screen 105 is provided on the filter 100, which covers the upper side, the rear side and the lower side of the filter 100.

[0046] In the present scheme, the filter screen 105 on the filter 100 is an integrally formed structure which is not prone to deformation or loosening during long-term use, and has strong deformation resistance. In addition, the integrally formed filter screen 105 reduces the installation steps and required tools, and does not need to check multiple splicing points during maintenance, thereby reducing the installation difficulty and time cost, and simplifying the maintenance process.

[0047] As shown in Figure 3 and Figure 4 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 the inner surface near the connection end, and the support portions 1014 are plate-shaped members extending along the height direction of the filter 100.

[0048] The inner surface of the filter screen 105 also has a plurality of protruding portions 1015 extending along the width direction of the filter 100, and the protruding portions 1015 abut against the support portions 1014; wherein the extension direction of the plurality of filter units is the length direction of the filter 100, and the width direction is perpendicular to the length direction and the height direction.

[0049] According to 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 the present scheme, the inner surface of the filter screen 105 on the first support plate 101 and the second support plate 102 is provided with a support portion 1014, wherein the support portion 1014 is arranged at a position 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, which can provide support force to the filter screen 105 at the rear side of the filter 100, and can effectively prevent the filter screen 105 from being deformed greatly when a mouse or other external force applies force to the filter screen 105, thereby protecting the integrity of the filter screen 105.

[0050] In order to better fix the support portion 1014 on the filter screen 105, in an 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 protruding portions 1015 arranged at intervals, wherein the protruding portion 1015 is a plate-shaped structure with a predetermined thickness and extending along the width direction of the filter 100, one end of the length direction is connected with the support portion 1014, and the other end extends to the open end of the filter 100.

[0051] It is worth mentioning that since the hollow parts on the first support plate 101 and the second support plate 102 in the present scheme are arranged at intervals, the support parts 1014 are also arranged at intervals on the first support plate 101 and the second support plate 102.

[0052] As can be understood by those skilled in the art, the support parts 1014 and the filter screen 105 are arranged synchronously, that is, when the filter screen 105 is arranged on only the first support plate 101 or the second support plate 102, the support parts 1014 are also arranged on only the first support plate 101 or the second support plate 102 correspondingly.

[0053] The above scheme describes in detail the arrangement form of the filter screen 105 on the filter 100, and the specific structure of the connecting piece 104 and how the connecting piece 104 connects the two filter cartridges 103 together.

[0054] As shown in Figure 3 , Figure 6 and Figure 7 , in a specific embodiment, the filter cartridge 103 is a square plate-shaped piece 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 toward the open end and the connecting end respectively; the connecting piece 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, the included angle between the extension planes of the first connecting plate 1041 and the third connecting plate 1043 is the same as the angle between the two filter cartridges 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 cartridges 103, and the second connecting plate 1042 limits the end wall of the filter cartridge 103 toward the connecting end.

[0055] In the present scheme, the inner surface of the first support plate 101 has mounting grooves formed by a plurality of protruding ribs 1011 arranged on the inner surface, and correspondingly, the inner surface of the second support plate 102 also has mounting grooves formed by a plurality of protruding ribs 1011, wherein the size and number of the mounting grooves are matched with the number and size of the filter cartridges 103. In addition, the filter cartridges 103 on the filter 100 in the present scheme are square plate-shaped pieces with a preset thickness, which not only have two side walls and two end walls, but also have two top walls arranged toward the first support plate 101 and the second support plate 102 respectively. When the filter cartridges 103 are in the assembled state, the two top walls are limited in the mounting grooves on the first support plate 101 and the second support plate 102 respectively.

[0056] As shown in Figure 6 and Figure 7As shown, the connecting piece 104 in the present solution is in the form of a groove, which comprises 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 obtuse, and the included angle between the third connecting plate 1043 and the second connecting plate 1042 is also obtuse. In addition, in the present solution, the included angle between the extension surfaces of the first connecting plate 1041 and the third connecting plate 1043 is the same as the included angle between the two filter cartridges 103 connected at the connecting end.

[0057] When the connecting piece and the filter cartridges are in the 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 cartridges 103 away from each other, and the second connecting plate 1042 abuts against and limits the end walls of the two filter cartridges 103 facing the connecting end. That is, the first connecting plate 1041 and the third connecting plate 1043 of the connecting piece 104 limit the filter cartridges 103 in the length direction of the filter 100, and the second connecting plate 1042 limits the filter cartridges 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 cartridges 103 in the height direction of the filter 100.

[0058] As can be understood by those skilled in the art, in order to better fix the filter cartridges 103, glue can be injected on the mounting grooves and the connecting piece 104, so that the connection between the filter cartridges 103 and the mounting grooves and the connecting piece 104 is more firm.

[0059] In a specific embodiment, there is a gap between the two filter cartridges 103 connected by the connecting piece 104 at the connecting end; the inner surface of the second connecting plate 1042 is provided with a limiting piece 1044 protruding therefrom, which is inserted into the gap to limit the filter cartridges 103.

[0060] In the present scheme, the two filter cartridges 103 at the connection end are not in abutment with each other, and there is a spacing between the two. At the same time, the connecting piece 104 in the present scheme is further provided with a limiting piece 1044. Specifically, the limiting piece 1044 is provided on 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 piece 1044 is the height direction of the filter 100. When the filter cartridge 103 is connected with the connecting piece 104, the limiting piece 1044 is inserted into the spacing between the two filter cartridges 103 and limits the two filter cartridges 103 respectively. In the present scheme, through the cooperation of the limiting piece 1044 and the spacing, the connection strength between the filter cartridge 103 and the connecting piece 104 is enhanced, effectively preventing the displacement or shaking of the filter cartridge 103 at the connection end, and ensuring that the filter cartridge 103 remains stable during use.

[0061] In a specific embodiment, the limiting piece 1044 divides the first connecting plate 1041 into two parts, and the included angle between the two parts and the limiting piece 1044 is an obtuse angle greater than ninety degrees, which can be 90.5 degrees, 91 degrees, or other degrees. That is, the two parts of the first connecting plate 1041 are slightly outwardly extended. Such arrangement can make the glue on the connecting piece 104 quickly pass through the inner surface of the first connecting piece 104, reduce the glue climbing on the surface of the filter cartridge 103, reduce the amount of glue used, and reduce the production cost.

[0062] As shown in Figure 3 In a specific embodiment, the two adjacent filter cartridges 103 at the open end are fixed by the connecting piece 104.

[0063] In the present scheme, not only the end portions of the two adjacent filter cartridges 103 at the connection end are connected by the connecting piece 104, but also the two adjacent filter cartridges 103 at the open end are connected and fixed by the connecting piece 104.

[0064] As shown in Figure 3 and Figure 5 In a specific embodiment, the protruding rib 1011 has a blocking portion 1012 extending towards the inner side wall of the mounting groove for limiting the first connecting plate 1041 and the third connecting plate 1043.

[0065] In the present scheme, at least one set of opposite arranged blocking parts 1012 are arranged on the two ribs 1011 forming an installation slot, and the blocking parts 1012 are respectively used for limiting the first connecting plate 1041 and the third connecting plate 1043 of the connecting piece 104. Specifically, the two blocking parts 1012 are plate-shaped structures or protrusions arranged towards the length direction of the filter 100. When the filter element 103 and the connecting piece 104 are both assembled between the first support plate 101 and the second support plate 102, one blocking part 1012 abuts and limits the end of the first connecting plate 1041 away from the second connecting plate 1042, and the other blocking part 1012 abuts and limits the end of the third connecting plate 1043 away from the second connecting plate 1042.

[0066] As shown in the specific embodiment, Figure 5 Figure 7 the end of the second connecting plate 1042 is provided with a fixing part 1045 matched with the extension part 1013, and the extension part 1013 is inserted into the fixing part 1045 to limit the connecting piece 104.

[0067] Specifically, the fixing part 1045 is a semicylindrical groove arranged on the second connecting plate 1042, and the fixing part 1045 is connected with the limiting part 1044 and has the same extension direction as the limiting part 1044.

[0068] In the present scheme, the filter element 103 is arranged in a W shape along the length direction of the filter 100, and correspondingly, the installation slots 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. Those skilled in the art can understand that one installation slot is formed by two ribs 1011, and two installation slots are formed by four ribs 1011. In the present scheme, among the four ribs 1011 forming two adjacent installation slots, the ends of the two adjacent ribs 1011 are connected with each other. The rib 1011 has two extension parts 1013 arranged towards the open end and the connecting end 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 part 1045 matched with the extension part 1013. Specifically, the fixing part 1045 is a semicylindrical groove arranged on the inner surface of the second connecting plate 1042, and one end of the groove abuts with the limiting part, and the other end extends towards the open end or the connecting end of the filter 100. During installation, the extension part 1013 is inserted into the fixing part 1045, so that the connecting piece 104 is better limited in the installation slot.

[0069] As​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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] It is worth mentioning that the length direction of the filter 100 in the present scheme refers to the extension direction of the plurality of filter units, the height direction 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 connecting end.

[0081] While several embodiments of the disclosure have been shown and described herein, it is to be understood that the embodiments are merely exemplary. Numerous changes, substitutions, and alterations can be made to the embodiments without departing from the spirit and scope of the disclosure. It is understood that various alternatives to the embodiments of the disclosure described herein can be employed in practicing the present disclosure. It is intended that the following claims define the scope of the disclosure and that methods equivalent to those claims recited herein are within the scope of the disclosure.
