Description

Technical Field

[0001] This utility model relates to the field of medium-efficiency filter elements, and in particular to a combined medium-efficiency filter element. Background Technology

[0002] Medium-efficiency filter cartridges are used for air filtration, primarily to filter particulate matter and harmful substances in the air, ensuring clean and healthy indoor air. Medium-efficiency filter cartridges come in various specifications, commonly including bag-type and non-bag-type cartridges. Bag-type medium-efficiency filter cartridges include different efficiency levels such as F5, F6, F7, F8, and F9, while non-bag-type cartridges include plate-type medium-efficiency filters, partition-type medium-efficiency filters, and combination medium-efficiency filters.

[0003] When installing and using filter cartridges, a mounting frame is usually used to wrap and restrict their shape. This not only ensures the stability of the filter cartridge's shape during use but also facilitates the installation and removal of the filter cartridge. After a period of use, the filter cartridge needs to be disassembled and replaced. However, existing filter cartridge frames are usually integrally formed by rivets or welding. Therefore, when replacing the filter cartridge, the filter cartridge frame must be installed and replaced together, which increases the replacement cost and makes it inconvenient to separate the filter cartridge and the mounting frame for replacement. Utility Model Content

[0004] The purpose of this invention is to provide a combined medium-efficiency filter element to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined medium-efficiency filter element, comprising:

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] This utility model provides, for example Figure 1-3 The image shows a combined medium-efficiency filter element.

[0036] Example 1

[0037] The system includes a mounting frame 1, a filter element 2, a baffle 3, a top plate 4, a connecting plate 5, and a locking element 6. The filter element 2 is slidably fitted inside the mounting frame 1. The end of the baffle 3 is fixedly connected to the mounting frame 1. The baffle 3 is used to restrict and restrain the sides of the filter element 2. Multiple baffles 3 on both sides of the filter element 2 can improve the impact resistance of the filter element 2 and reduce the possibility of bending damage. The top plate 4 is set on the top of the mounting frame 1 and is used to limit and restrain the top of the filter element 2. The connecting plate 5 is fixedly connected to the top of the mounting frame 1. The bottom of the top plate 4 has a connecting groove that matches the connecting plate 5. The locking element 6 is rotatably set inside the top plate 4. The locking element 6 is used to lock and limit the connecting plate 5, thereby ensuring the stability of the top plate 4 installed on the top of the mounting frame 1. Rotating the locking element 6 can release the locking state of the connecting plate 5, thereby directly disassembling the top plate 4 and disassembling and replacing the filter element 2 inside the mounting frame 1.

[0038] Specifically, the locking component 6 includes a shaft 61, a knob 63, a through hole, a notch 62, and a slot. The outer wall of the shaft 61 is rotatably inserted into the top plate 4. The through hole is located on the front of the mating plate 5, and the outer wall of the shaft 61 is slidably engaged with the inner cavity of the through hole. The knob 63 is fixedly connected to the end of the shaft 61, and its outer wall is rotatably connected to the top plate 4. The knob 63 can not only drive the shaft 61 to rotate but also limit its movement, thus ensuring the stability of the rotatable connection between the shaft 61 and the top plate 4. The notch 62 is located on the outside of the shaft 61, and the slot is located on the top of the mating plate 5. The inner cavity of the slot communicates with the inner cavity of the through hole. The inner cavity of the slot corresponds to the notch 62 on the outside of the shaft 61, and the width of the slot is smaller than the diameter of the shaft 61. Figure 2 As shown, when the notch 62 on the outside of the shaft 61 is located at the top and bottom of the shaft 61, the shaft 61 can be engaged in the through hole on the mating plate 5, thereby engaging and limiting the mating plate 5, so that the mating plate 5 and the top plate 4 are in a stable engaged state. When the shaft 61 is rotated so that the notch 62 is located on both sides of the shaft 61, the mating plate 5 can slide and separate from the shaft 61 through the notch 62 on the outside of the shaft 61 through the slot, thereby disassembling the top plate 4.

[0039] Example 2

[0040] Based on embodiment 1, a limiting component 7 is also included. The limiting component 7 is disposed on the docking plate 5. The limiting component 7 is used to lock and limit the shaft 61. The limiting component 7 includes a limiting block 71. The top of the outer wall of the limiting block 71 is slidably locked into the inside of the notch 62, that is, the top of the limiting block 71 is in contact with the inner wall of the notch 62 on the shaft 61, thereby limiting the shaft 61.

[0041] Furthermore, the limiting component 7 also includes a mounting groove 72 and a support spring 74. The mounting groove 72 is opened at the bottom of the docking plate 5. The bottom of the outer wall of the limiting block 71 is slidably sleeved with the inner cavity of the mounting groove 72. The support spring 74 is set on the side of the limiting block 71 away from the shaft 61. The support spring 74 can give the limiting block 71 a spring force toward the shaft 61, thereby limiting the limiting block 71 to the shaft 61, so that the shaft 61 remains stable without external force, and thus the shaft 61 is in a stable state and is engaged with the docking plate 5.

[0042] Furthermore, the limiting component 7 also includes a positioning plate 73 and a connecting rope 75. The positioning plate 73 is snapped into the bottom of the docking plate 5, and the top of the positioning plate 73 is in contact with the support spring 74. The ends of the connecting rope 75 are fixedly connected to the positioning plate 73 and the limiting block 71 respectively. The connecting rope 75 can limit the limiting block 71, preventing the limiting block 71 from sliding away from the docking plate 5 under the action of the support spring 74 after the docking plate 5 is separated from the shaft 61.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
