[0036] The principles and features of the present application are described below in conjunction with the accompanying drawings, and the examples are only used to explain the present application and not to limit the scope of the present application.

[0037] As shown in the drawings, Figures 1 to 9 The present application embodiment provides an electrostatic filter screen 100, comprising: an electrostatic filter core 1 and a frame 2.

[0038] Among them, the electrostatic filter core 1 comprises a plurality of filter sheets 11. The plurality of filter sheets 11 are arranged in parallel and spaced apart along the thickness direction of the filter sheet 11.

[0039] As shown in the drawings, Figure 5 and Figure 6 The frame 2 is provided with a plurality of limiting grooves 21 at both ends in the length direction, and each filter sheet 11 is clamped in the corresponding limiting groove 21 at both ends in the length direction.

[0040] The electrostatic filter screen 100 provided by the present application embodiment is provided with a plurality of limiting grooves 21 at both ends in the length direction of the frame 2, so that each filter sheet 11 can be clamped between the corresponding two limiting grooves 21 during assembly. After all the filter sheets 11 are installed, the alignment of the plurality of filter sheets 11 can be achieved, and the relative stability of the position of the plurality of filter sheets 11 can be achieved. Therefore, the plurality of filter sheets 11 of the electrostatic filter core 1 of the present scheme can be directly aligned by the frame 2, and the assembly limiting between the electrostatic filter core 1 and the frame 2 can be achieved, thereby the alignment process between the scattered plurality of filter core fixing clamps 3 and the scattered plurality of filter sheets 11 can be cancelled, thereby facilitating the simplification of the assembly process of the electrostatic filter screen 100, thereby improving the production efficiency of the product, and reducing the labor cost.

[0041] In some exemplary embodiments, as Figure 1As shown, the electrostatic filter screen 100 further comprises a plurality of filter core fixing clamps 3 connected with the frame 2. The filter core fixing clamp 3 comprises a clamp body 31 and a plurality of clamp teeth 32 arranged on the clamp body 31. The plurality of clamp teeth 32 are arranged in parallel and spaced apart along the thickness direction of the filter sheet 11, and the plurality of clamp teeth 32 are arranged to clamp the plurality of filter sheets 11 to fix the electrostatic filter core 1. The filter sheet 11 is clamped between adjacent clamp teeth 32. The filter core fixing clamp 3 is roughly in a comb structure. Due to the clamping action of the clamp teeth 32, the spacing between the filter sheets 11 is relatively fixed. By adjusting the gap size between the clamp teeth 32, the spacing size between the filter sheets 11 can be adjusted, and then the ventilation volume of the electrostatic filter screen 100 is adjusted.

[0042] The frame 2 can play a role of alignment and preliminary limiting with the electrostatic filter core 1. The arrangement of the plurality of filter core fixing clamps 3 can further limit the electrostatic filter core 1, thereby effectively improving the position stability and use reliability of the electrostatic filter core 1.

[0043] Moreover, since the plurality of filter sheets 11 of the electrostatic filter core 1 have realized alignment and relative stability of position, the insertion and assembly process between the plurality of filter sheets 11 of the electrostatic filter core 1 and the filter core fixing clamp 3 can also be greatly simplified, which is beneficial to improve the production efficiency of the product and reduce the labor cost.

[0044] In some exemplary embodiments, as shown, Figure 1 As shown, the plurality of filter core fixing clamps 3 are divided into a first fixing clamp group and a second fixing clamp group. The first fixing clamp group and the second fixing clamp group are arranged to be inserted into the electrostatic filter core 1 from opposite directions, so that the clamp body 31 of the first fixing clamp group and the clamp body 31 of the second fixing clamp group respectively abut against both ends of the thickness direction of the electrostatic filter core 1. The thickness direction of the electrostatic filter core 1 is consistent with the width direction of the filter sheet 11.

[0045] The plurality of filter core fixing clamps 3 are divided into a first fixing clamp group and a second fixing clamp group, and the first fixing clamp group and the second fixing clamp group are respectively inserted into the electrostatic filter core 1 from opposite directions, so that the electrostatic filter core 1 has a stop structure on both sides. Due to the stop action of the clamp body 31 of the first fixing clamp group and the clamp body 31 of the second fixing clamp group, the electrostatic filter core 1 cannot be pulled out of the filter core fixing clamp 3 along the insertion direction of the filter core fixing clamp 3, thereby avoiding the electrostatic filter core 1 from being loosened and falling off, improving the use reliability of the electrostatic filter screen 100, and the anti-falling-off filter screen can be omitted, which is beneficial to simplify the structure of the electrostatic filter screen 100 and reduce the production cost.

[0046] In some exemplary embodiments, the two ends of the length direction of the clamp body 31 are provided with a connecting part, and the frame 2 is provided with a connecting matching part matched with the connecting part. The matching of the connecting part and the connecting matching part can realize the assembly and fixation between the filter core fixing clamp 3 and the frame 2. As for the specific connection mode, it is not limited, for example, the modes such as clamping, fastener connection, plug-in connection, etc.

[0047] One end of the clamping tooth 32 is connected with the clamping body 31, and the other end of the clamping tooth 32 protrudes from the connecting portion in the length direction of the clamping tooth 32, so that the connecting portion and the adjacent clamping tooth 32 enclose a sliding space 33 (as shown in Figure 2 The filter core fixing clamp 3 can be partially inserted into the electrostatic filter core 1, and then slid along the length direction of the electrostatic filter core 1 to the corresponding connecting portion, so as to be connected with the connecting portion.

[0048] In this way, the filter core fixing clamp 3 can be partially inserted into the electrostatic filter core 1 (for example, about half), and then slid along the electrostatic filter core 1 to the corresponding connecting portion, and then the connection between the connecting portion and the connecting portion can be realized. In this way, the filter core fixing clamp 3 does not need to be accurately positioned during installation, and can be randomly inserted into any position of the electrostatic filter core 1 and then slid to the corresponding connecting portion, which can reduce the installation difficulty of the filter core fixing clamp 3 and is beneficial to further improve the assembly efficiency.

[0049] In addition, the sliding space 33 greatly reduces the requirements for the frame 2, and the frame 2 does not need to be additionally provided with a sliding rail or a base containing the sliding rail, so that the structure of the frame 2 can be simplified, and the two side frames (i.e., the first side frame 241 and the second side frame 242 described below) of the frame 2 can be prepared by an extrusion molding process to reduce the mold cost.

[0050] In some exemplary embodiments, both ends of the clamping body 31 in the length direction are provided with connecting portions, and the frame 2 is provided with connecting portions matched with the connecting portions. The connecting portion is provided as a clamping hook 311, as shown in Figure 2 The connecting portion is provided as a clamping groove 22, as shown in Figure 8 The clamping hook 311 is clamped with the clamping groove 22, as shown in Figure 9 The clamping connection mode is simple and convenient to operate, and is beneficial to further improve the assembly efficiency.

[0051] Of course, the connection mode of the connecting portion and the connecting portion is not limited to the above-mentioned clamping connection mode, and can also be other modes such as fastener connection and plug-in connection.

[0052] In some exemplary embodiments, as shown in Figure 9 The clamping hook 311 includes a base portion 3111 arranged in parallel and spaced apart with the clamping tooth 32, and a hook portion 3112 connected with the base portion 3111 and arranged inclinedly relative to the base portion 3111. As shown in Figure 7 and Figure 8 The clamping groove 22 is provided with a first slot 221 and a second slot 222 connected in communication. The first slot 221 is arranged to extend along the length direction of the clamping body 31, and the second slot 222 is arranged to extend along the length direction of the clamping tooth 32.

[0053] The hook portion 3112 is arranged to be inserted into the clamping groove 22 through the first slot 221 and to hook the inner wall of the clamping groove 22 to limit the clamping hook 311 from disengaging from the clamping groove 22, and the base portion 3111 is inserted into the second slot 222, as shown in Figure 9

[0054] In the assembly process of the filter element fixing clamp 3 and the frame 2, the filter element fixing clamp 3 needs to be inserted along the thickness direction of the electrostatic filter element 1 (i.e. the width direction of the filter clamp) until it is clamped with the frame 2, so the clamping groove 22 needs the first slot 221. The arrangement of the second slot 222 can reduce the interference between the clamping hook 311 and the frame 2 during assembly, thereby facilitating the assembly difficulty, and also allowing the thickness of the base portion 3111 of the clamping hook 311 to be appropriately increased to reduce the risk of breakage of the clamping hook 311 and improve the use reliability of the clamping hook 311.

[0055] In some embodiments, the thickness of the base portion 3111 of the clamping hook 311 along the length direction of the clamping body 31 is denoted as W3, the thickness of the hook portion 3112 of the clamping hook 311 along the length direction of the clamping body 31 is denoted as W4, and the thickness of the clamping tooth 32 along the length direction of the clamping body 31 is denoted as W5. Wherein, W3>W4, W3>W5, as shown in Figure 9 It can be seen that the strength and use reliability of the clamping hook 311 can be effectively ensured. The thickness of the hook portion 3112 is relatively thin, which facilitates elastic deformation to reduce the assembly difficulty and improve the assembly efficiency.

[0056] In some exemplary embodiments, as shown in Figure 9 The two ends of the hook portion 3112 are respectively provided with a first stop portion 3113 and a second stop portion 3114. The first stop portion 3113 is arranged to hook the inner wall of the end of the first slot 221 away from the second slot 222, as shown in Figure 9 The second stop portion 3114 is arranged to hook the inner wall of the end of the second slot 222 away from the first slot 221, as shown in Figure 9

[0057] In this way, the first stop portion 3113 and the second stop portion 3114 can stop from two parts and two directions, which can not only avoid the clamping hook 311 from disengaging from the first slot 221, but also avoid the clamping hook 311 from disengaging from the second slot 222, thereby effectively improving the position stability and use reliability of the clamping hook 311, and further effectively improving the position stability and use reliability of the filter element fixing clamp 3.

[0058] In some embodiments, the second stop portion 3114 and the adjacent clamping tooth 32 enclose a sliding space 33, as shown in Figure 2

[0059] ​​​In some example embodiments, the card body 31 is further provided with an extension 312 at both ends in the length direction, as shown in Figure 2 The extension 312 is adapted to the first notch 221 and is arranged to be inserted into the corresponding first notch 221 to shield the first notch 221, as shown in Figure 9 .

[0060] In this way, the first notch 221 of the frame 2 is not exposed after the filter core fixing card 3 is assembled in place, which is conducive to improving the appearance and integrity of the electrostatic filter net 100.

[0061] In some example embodiments, the clamping tooth 32 is provided with a first protruding part 321 on the side wall of at least one side in the length direction of the card body 31, as shown in Figure 3 and Figure 4 The first protruding part 321 is arranged to abut against the filter sheet 11 to clamp the filter sheet 11. In this way, the clamping force of the filter core fixing card 3 on the filter sheet 11 is improved, thereby improving the position stability and use reliability of the electrostatic filter core 1.

[0062] In some example embodiments, the first protruding part 321 is arranged as a protruding rib extending in the length direction of the clamping tooth 32, as shown in Figure 3 In this way, the contact area with the filter card can be increased, thereby improving the clamping force on the filter sheet 11.

[0063] In some embodiments, the protruding rib is provided with a guide inclined surface 3211 at the end away from the card body 31, as shown in Figure 3 This facilitates smooth insertion of the filter core fixing card 3 into the electrostatic filter core 1.

[0064] In other embodiments, the first protruding part 321 can also be arranged as a convex bump, a convex point, a protruding rib extending in the width direction of the filter sheet 11, etc. Alternatively, the clamping tooth 32 can also be arranged in a wave shape, a zigzag shape, etc., so that the clamping tooth 32 itself has the first protruding part 321.

[0065] In some example embodiments, the clamping tooth 32 is provided with an anti-disengagement part 322 at the end away from the card body 31, as shown in Figure 2 and Figure 3 The anti-disengagement part 322 abuts against the filter sheet 11 to limit the disengagement of the filter core fixing card 3 from the electrostatic filter core 1.

[0066] The arrangement of the anti-disengagement part 322 can improve the assembly reliability of the filter core fixing card 3 and the electrostatic filter core 1, effectively reducing the risk of separation of the filter core fixing card 3 and the electrostatic filter core 1. The specific shape of the anti-disengagement part 322 is not limited, for example, it can be an end portion arranged to be inclined away from the card body 31 (as shown in Figure 2 and Figure 3The hook-shaped structure can be arranged in a direction away from the card body 31 or in a direction close to the card body 31.

[0067] In some exemplary embodiments, as shown in FIG. 1, the frame 2 comprises a first base 231, a first side frame 241, a second base 232 and a second side frame 242 connected in sequence. Figure 1 The first base 231 and the second base 232 are arranged to be electrically connected with the electrostatic filter element 1 and the power supply.

[0068] In this way, the electrostatic filter element 1 can be electrically connected with the power supply through the frame 2, that is, the frame 2 has the functions of the frame 2 and the base, so that the base in the related art can be omitted, and the structure of the electrostatic filter net 100 is greatly simplified, and the production cost is reduced.

[0069] The first base 231 or the second base 232 can be arranged to be electrically connected with the electrostatic filter element 1 and the power supply, and the first base 231 and the second base 232 can be respectively provided with a positive electrode connecting end and a negative electrode connecting end. The positive electrode connecting end is connected with the positive electrode of the power supply and the positive electrode filter sheet of the electrostatic filter element 1, and the negative electrode connecting end is connected with the negative electrode of the power supply and the negative electrode filter sheet of the electrostatic filter element 1. Alternatively, the first base 231 and the second base 232 can be arranged to be electrically connected with the electrostatic filter element 1 and the power supply, and the first base 231 and the second base 232 can be respectively connected with the positive electrode and the negative electrode of the power supply and electrically connected with the positive electrode filter sheet and the negative electrode filter sheet of the electrostatic filter element 1.

[0070] In some embodiments, the power supply can be a high-voltage pack, which can convert low-voltage electricity into high-voltage electricity. In this way, the power supply of the electrostatic filter net 100 is directly electrically connected with the electric control device 300 of the air treatment equipment, so that the electrostatic filter net 100 can be used in an electrified manner, and the air treatment equipment is convenient to control. A plate-shaped electrode can be arranged in the first base 231 / second base 232 to contact the corresponding positive electrode filter sheet or negative electrode filter sheet to achieve electrical connection.

[0071] In some embodiments, the first side frame 241 and the second side frame 242 can be fixedly connected with the first base 231 and the second base 232 by means of buckling connection, fastener connection, plug-in connection and the like. The first side frame 241 and the second side frame 242 are connected with the filter element fixing card 3. The first side frame 241 and the second side frame 242 are provided with the above-mentioned card slot 22. Furthermore, as shown in FIG. 1, Figure 7 and Figure 8As shown, the first frame 241 and the second frame 242 are each provided with two sets of notches (each set of notches includes a first notch 221 and a second notch 222), one set of notches is used to be connected with the filter core fixing clamps 3 of the first fixing clamp group, and the other set of notches is used to be connected with the filter core fixing clamps 3 of the second fixing clamp group.

[0072] In some exemplary embodiments, the first frame 241 and the second frame 242 are provided as extruded parts.

[0073] In the related art, the frame 2 is an injection molded part, and different models need to develop molds respectively, and the mold cost is relatively high. In the embodiments of the present application, the first frame 241 and the second frame 242 are provided as extruded parts, which can be processed into any length as needed through extrusion molding to adapt to different models, so that the mold cost can be greatly reduced. The first base 231 and the second base 232 can be provided as injection molded parts.

[0074] The first frame 241 and the second frame 242 can be provided with a folded edge to facilitate the connection of the electrostatic filter screen 100 with an air handling device such as an air conditioner.

[0075] In some exemplary embodiments, as shown in Figure 6 As shown, the width of the notch of the limiting groove 21 at one end along the length direction of the electrostatic filter core 1 in the thickness direction of the filter sheet 11 is denoted as W1, and the width of the groove bottom of the limiting groove 21 at one end along the length direction of the electrostatic filter core 1 in the thickness direction of the filter sheet 11 is denoted as W2, W1>W2.

[0076] In this way, the limiting groove 21 has a structure of wide outside and narrow inside, and correspondingly, the tool for processing the limiting groove 21 on the mold can have a structure of thick root and narrow tip, which is beneficial to reduce the risk of mold tool breakage. Moreover, the wide structure of the limiting groove 21 facilitates smooth insertion of the filter sheet 11 into the limiting groove 21, and the narrow structure facilitates clamping of the filter sheet 11.

[0077] In addition, after the electrostatic filter core 1 is electrically connected with the first base 231 / second base 232, insulating glue can be injected into the limiting groove 21 to improve the safety performance of the electrostatic filter screen 100. The relatively narrow limiting groove 21 can effectively block the overflow of glue, facilitating the molding of insulating glue.

[0078] In some exemplary embodiments, as shown in Figure 6 As shown, the side wall of the limiting groove 21 is provided with a second protruding part 251, and the second protruding part 251 is arranged in abutting cooperation with the filter sheet 11. In this way, it is beneficial to improve the clamping force of the frame 2 on the filter sheet 11, thereby being beneficial to improve the position stability and use reliability of the electrostatic filter core 1.

[0079] In some exemplary embodiments, as shown in Figure 5As shown, the two ends of the frame 2 in the length direction are respectively provided with a plurality of limiting teeth 25 arranged along the width direction of the electrostatic filter element 1, and a limiting groove 21 is formed between adjacent limiting teeth 25. Figure 6 As shown, the two ends of the frame 2 in the length direction are respectively provided with a plurality of limiting teeth 25 arranged along the width direction of the electrostatic filter element 1, and a limiting groove 21 is formed between adjacent limiting teeth 25.

[0080] In this way, the spacing between adjacent bottom plates 26 is relatively narrow, facilitating effective clamping of the filter sheet 11; and the spacing between adjacent limiting teeth 25 is relatively wide, facilitating glue injection, which can be injected from this area, can effectively block the overflow of glue, and facilitate the molding of insulating glue.

[0081] The shape of the second protruding portion 251 is not limited, for example, it can be set as a convex, a protruding point, a protruding rib extending along the width direction of the filter sheet 11 (as shown in Figure 6 As shown, the limiting tooth 25 can also be set as a wave shape, a zigzag shape, etc., so that the limiting tooth 25 itself has the second protruding portion 251.

[0082] As shown, the limiting tooth 25 can also be set as a wave shape, a zigzag shape, etc., so that the limiting tooth 25 itself has the second protruding portion 251.
