Description

Technical Field

[0001] This utility model relates to the field of ventilation and filtration technology, and in particular to a filtration device that facilitates the installation and replacement of filter membranes. Background Technology

[0002] With increasing public concern about air quality, air vent filtration devices, as key components for controlling air quality, have been widely used in residential, commercial, and industrial environments. Current technologies typically involve various filter membranes, with air purification achieved through the winding of these membranes.

[0003] For example, in the prior art, there is a Chinese utility model patent document with publication number CN201032212Y and publication date of March 5, 2008. The technical solution disclosed in this patent document is as follows: a range hood with a filter membrane that is easy to clean, wherein the two sides of the casing have a filter membrane inlet and outlet that are arranged opposite to each other and located on the same horizontal line; the two sides of the casing are provided with a filter membrane input mechanism and an output mechanism.

[0004] Although the above technical solution includes a filter membrane input and output mechanism, the filter membrane needs to be passed through the narrow inlet and outlet channels on the side of the air vent during installation. If the size of the narrow inlet and outlet channels on the side of the air vent is too large, the filter membrane installation will be convenient, but air leakage will be more serious, resulting in poor air filtration effect. To meet the air filtration effect, the size of the narrow inlet and outlet channels on the side of the air vent cannot be too large, and the narrow channels will make it inconvenient to install the filter membrane. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model proposes a filtration device that is easy to install and replace the filter membrane, which can improve the convenience of installation while taking into account the filtration effect.

[0006] This utility model is achieved by adopting the following technical solution:

[0007] A filtration device that facilitates the installation and replacement of filter membranes includes a filter membrane, a filter membrane input mechanism, and a filter membrane output mechanism, and also includes a mounting plate for detachable connection with an air vent panel; the filter membrane input mechanism and the filter membrane output mechanism are respectively connected to the mounting plate via brackets; one end of the filter membrane is connected to the filter membrane output mechanism, and the other end cooperates with the upper or lower surface of the mounting plate to guide and maintain the filter membrane in a flat and wrinkle-free state before being connected to the filter membrane input mechanism.

[0008] The mounting plate is flat and has through holes that match the air vents, with the width of the through holes being smaller than the width of the filter membrane. The filter membrane input mechanism and the filter membrane output mechanism are located below the mounting plate. One end of the filter membrane is connected to the filter membrane output mechanism, and after being laid along the upper surface of the mounting plate and completely covering the through holes, the other end is connected to the filter membrane input mechanism.

[0009] The mounting plate has arc-shaped transition pieces at both ends facing the filter membrane input mechanism and the filter membrane output mechanism, respectively.

[0010] One end of the mounting plate is hinged to the air vent panel, and the other end is detachably connected to the air vent panel via a connector.

[0011] The connector includes a latch and a latch base; one end of the latch is connected to the air vent panel, and the other end is provided with a rotating handle; the latch base is set on the mounting plate, and the latch base is provided with a locking groove that penetrates the mounting plate; the rotating handle can pass through the locking groove in a vertical direction, and by rotating, the outer contour of the rotating handle is misaligned with the position of the locking groove, thereby realizing a detachable connection between the air vent panel and the mounting plate.

[0012] The filter membrane input or output points of the filter membrane input mechanism and the filter membrane output mechanism are located on the outside of the mounting plate, respectively.

[0013] The mounting plates are a first mounting plate and a second mounting plate arranged side by side. The first mounting plate and the second mounting plate are respectively fixed to both sides of the air outlet panel by a detachable connection. The filter membrane input mechanism is connected to the first mounting plate by a bracket, and the filter membrane output mechanism is connected to the second mounting plate by a bracket. One end of the filter membrane is connected to the filter membrane output mechanism, and it is laid sequentially along the lower surface of the second mounting plate and the first mounting plate. After it is attached to the surface of the air outlet, the other end is connected to the filter membrane input mechanism.

[0014] The filter membrane input point of the filter membrane input mechanism is located above the lower surface of the first mounting plate, and the filter membrane output point of the filter membrane output mechanism is located above the lower surface of the second mounting plate.

[0015] The filter membrane input mechanism includes a low-speed motor, a first damper, and an input shaft for winding the filter membrane; the low-speed motor and the first damper are detachably connected to both ends of the input shaft and are fixedly mounted on the mounting plate by a bracket.

[0016] The filter membrane output mechanism includes a second damper, a third damper, and an output shaft for winding the filter membrane; the second damper and the third damper are detachably connected to both ends of the output shaft and are fixedly mounted on the mounting plate by a bracket.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. In this invention, the interaction between the filter membrane and the upper or lower surface of the mounting plate effectively guides and shapes the filter membrane, allowing it to perform its filtering function better at the air outlet. Furthermore, this interaction allows for the pre-setting of the filter membrane's path, enabling the mounting plate, filter membrane, filter membrane input mechanism, and filter membrane output mechanism to form an independently operating module. During installation, simply connect the entire module to the air outlet panel, making installation more convenient and eliminating the need to modify the internal structure of the ventilation system. Moreover, the detachable connection between the mounting plate and the air outlet panel further simplifies and facilitates installation and replacement.

[0019] In this invention, the mounting plate can be designed to adapt to different sizes of air vents, making it suitable for various specifications of air supply or return vents.

[0020] 2. In this utility model, the mounting plate is flat. This structure allows the filter membrane to be laid along the upper surface of the mounting plate and completely cover the through-holes. The mounting plate not only provides good support for the filter membrane but also maintains its flatness and wrinkle-free state, facilitating better filtration. Furthermore, the filter membrane input and output mechanisms are located below the mounting plate, saving space and facilitating the laying and recycling of the filter membrane.

[0021] 3. The arc-shaped transition piece enables a smooth transition of the filter membrane between the mounting plate and the filter membrane input and output mechanisms, facilitating better guidance of the filter membrane along the predetermined path.

[0022] 4. One end of the mounting plate is hinged to the air vent panel, and the other end is detachably connected to the air vent panel via a connector. This structure allows for quick assembly and disassembly. When the filter membrane needs to be replaced, the connector can be removed, and the mounting plate can be rotated via the hinge point between the mounting plate and the air vent panel, allowing for rapid installation of the filter membrane. This greatly facilitates the inspection, replacement, or cleaning of the filter membrane.

[0023] 5. The filter membrane input or output points are located on the outside of the mounting plate, which can avoid structural interference and make the filter membrane path layout more reasonable.

[0024] 6. Through the cooperation of the latch and the latch base, simply insert and rotate the handle to lock or unlock, making the installation and removal of the mounting plate more convenient. At the same time, the design of the latch base can also better cooperate with the hinge point to maintain the balance of the mounting plate.

[0025] 7. The mounting plates consist of a first mounting plate and a second mounting plate arranged side by side. The lower surfaces of the first and second mounting plates interact with the filter membrane, ensuring the filter membrane adheres closely to the air outlet surface for optimal filtration. Specifically, the first and second mounting plates provide stable support for the filter membrane at both ends, helping to prevent wrinkles or shifting and ensuring it remains flat, thus maintaining a high level of filtration efficiency.

[0026] 8. By understanding the positional relationship between the filter membrane input point and the first mounting plate, and the positional relationship between the filter membrane output point and the second mounting plate, the filter membrane path can be laid out more rationally.

[0027] 9. Through the cooperation of the input shaft, low-speed motor and first damper, the filter membrane can move automatically, and the speed and force can be adjusted to enhance the stability and reliability of the entire device.

[0028] 10. As a driven structure, the filter membrane output mechanism, through the setting of dual dampers, can ensure the stability of the output shaft during rotation and effectively control the release speed and smoothness of the filter membrane.

[0029] 11. Because the low-speed motor and the first damper are detachably connected to both ends of the input shaft, and the second and third dampers are detachably connected to both ends of the output shaft, the input shaft, output shaft, and filter membrane can form a scroll-like assembly. When replacing this assembly, the input shaft can be removed between the low-speed motor and the first damper, and the output shaft can be removed between the second and third dampers. Then, the output shaft with the new filter membrane is inserted between the second and third dampers, while the empty input shaft is inserted between the low-speed motor and the first damper. This structure allows for quick assembly and disassembly of the input and output shafts, and filter membrane replacement is modular, making the operation simple and fast.

[0030] 12. In the document with publication number CN201032212Y, if the air vent stops operating and the filter membrane lacks a mechanism to maintain tension, the filter membrane will sag due to gravity, and will not function properly when the air vent is restarted. This utility model, through the setting of a damper, can effectively maintain the flatness of the filter membrane and also solves the problem in the document with publication number CN201032212Y that requires a separate tension mechanism.

[0037] Example 1

[0038] As a basic embodiment of this utility model, the utility model includes a filtration device that facilitates the installation and replacement of the filter membrane, comprising a filter membrane 1, a filter membrane input mechanism, a filter membrane output mechanism, and a mounting plate 2 for detachable connection with an air vent panel. The filter membrane input mechanism and the filter membrane output mechanism can employ conventional techniques in the art, such as the structure described in Chinese Utility Model Patent Document CN201032212Y, which includes a guide wheel bracket on which guide wheels are mounted, and on which the filter membrane is wound.

[0039] In this embodiment, the filter membrane input mechanism and the filter membrane output mechanism are connected to the mounting plate 2 via the bracket 3. One end of the filter membrane 1 is connected to the filter membrane output mechanism, and the other end, after engaging with the upper or lower surface of the mounting plate 2, is connected to the filter membrane input mechanism. The engagement between the upper or lower surface of the mounting plate 2 and the filter membrane 1 guides the filter membrane 1 and maintains its flat, wrinkle-free state.

[0040] Example 2

[0041] In a preferred embodiment of this utility model, the present utility model includes a filtration device that facilitates the installation and replacement of the filter membrane, comprising a filter membrane 1, a filter membrane input mechanism, a filter membrane output mechanism, and a mounting plate 2. The filter membrane input mechanism and the filter membrane output mechanism are respectively connected to the mounting plate 2 via brackets 3.

[0042] The mounting plate 2 is flat and has through holes 4 that match the air vent, with the width of the through holes 4 being smaller than the width of the filter membrane 1. The mounting plate 2 can be detachably connected to the air vent panel via connectors. These connectors can employ conventional techniques, such as bolt and nut couplings, quick-locking mechanisms, snap-fit ​​connections, or pin and locking ring couplings.

[0043] The filter membrane input mechanism and the filter membrane output mechanism are located below the mounting plate 2. One end of the filter membrane 1 is connected to the filter membrane output mechanism. After being laid along the upper surface of the mounting plate 2 and completely covering the through hole 4, the other end is connected to the filter membrane input mechanism. Since the filter membrane 1 is laid on the upper surface of the mounting plate 2, it not only provides good guidance and support but also maintains a flat and wrinkle-free state.

[0044] Example 3

[0045] As another preferred embodiment of this utility model, please refer to the appendix to the specification. Figure 1 Included with instruction manual Figure 2 This utility model includes a filtration device that facilitates the installation and replacement of the filter membrane, comprising a filter membrane 1, a filter membrane input mechanism, a filter membrane output mechanism, and a mounting plate 2.

[0046] The mounting plate 2 is a single plate, and has through holes 4 that match the air vent, with the width of the through holes 4 being smaller than the width of the filter membrane 1. One end of the mounting plate 2 can be hinged to the air vent panel via a hinge, and the other end can be detachably connected to the air vent panel via a connector. In this embodiment, the hinge can be a conventional technique in the art, such as a hinge 14 or a chain. The connector includes a latch and a latch base 15. One end of the latch is connected to the air vent panel, and the other end has a rotating handle 16. This embodiment does not limit the connection relationship, as long as the rotating handle 16 can rotate while ensuring the stability of the connection with the air vent panel. Specifically, one end of the latch can be fixedly connected to the air vent panel, and the rotating handle 16 can rotate relative to the latch. The latch base 15 is disposed on the mounting plate 2, and the latch base 15 has a locking groove 17 that penetrates the mounting plate 2. Both the locking groove 17 and the rotating handle 16 have rectangular cross-sections. The length of the rotating handle 16 is less than the length of the locking groove 17, but greater than the width of the locking groove 17. The width of the locking groove 17 is greater than the width of the rotating handle 16. This dimensional design allows the rotating handle 16 to pass vertically through the locking groove 17. By rotating, the outer contour of the rotating handle 16 is misaligned with the locking groove 17; that is, when the rotating handle 16 and the locking groove 17 are not in a straight line, but preferably in a cross shape, locking is achieved. By rotating the rotating handle 16, when the rotating handle 16 and the locking groove 17 are in a straight line, locking is achieved. This connector allows for a detachable connection between the air vent panel and the mounting plate 2.

[0047] The filter membrane input mechanism includes a low-speed motor 9, a first damper 10, and an input shaft 8 for winding the filter membrane 1. The low-speed motor 9 and the first damper 10 are detachably connected to both ends of the input shaft 8 and are fixedly mounted on the mounting plate 2 via a bracket 3. The filter membrane output mechanism includes a second damper 12, a third damper 13, and an output shaft 11 for winding the filter membrane 1. The second damper 12 and the third damper 13 are detachably connected to both ends of the output shaft 11 and are fixedly mounted on the mounting plate 2 via a bracket 3.

[0048] The detachable connection can employ conventional techniques in the art, such as connection via coupling, flange connection, or quick-connect connection, and this embodiment does not modify these methods. The low-speed motor 9, the first damper 10, the second damper 12, and the third damper 13 are also conventional techniques in the art, and this embodiment does not modify them. Specifically, the low-speed motor 9 can be a 50KTYZ model, 1 rpm; the first damper 10, the second damper 12, and the third damper 13 can be permanent magnet dampers XT07.

[0049] One end of the filter membrane 1 is connected to the filter membrane output mechanism. After being laid along the upper surface of the mounting plate 2 and completely covering the through hole 4, the other end is connected to the filter membrane input mechanism. Since the filter membrane 1 is laid on the upper surface of the mounting plate 2, the mounting plate 2 can achieve good guidance and support, and maintain the filter membrane 1 in a flat and wrinkle-free state.

[0050] Furthermore, the filter membrane input mechanism and the filter membrane output mechanism are respectively located below the mounting plate 2, with the filter membrane input point of the filter membrane input mechanism and the filter membrane output point of the filter membrane output mechanism located on the outer side of the mounting plate 2. The mounting plate 2 has arc-shaped transition pieces 5 at both ends, facing the filter membrane input mechanism and the filter membrane output mechanism, respectively. This structure not only makes the arrangement of the components more reasonable but also makes the laying path of the filter membrane 1 more rational.

[0051] The above structure allows the filter membrane 1 to be laid flat on the air outlet surface, ensuring that all air passing through the air outlet passes through the filter membrane 1, thereby achieving effective air purification. When it is necessary to replace or clean the filter membrane 1, the locking between the mounting plate 2 and the air outlet panel can be released by rotating the rotating handle 16. By rotating the mounting plate 2 around the hinge point, the old filter membrane 1 can be easily removed from the filter membrane output mechanism and the filter membrane input mechanism and replaced with a new filter membrane 1.

[0053] In another preferred embodiment of this utility model, a filtration device is provided for easy installation and replacement of the filter membrane, comprising a filter membrane 1, a filter membrane input mechanism, a filter membrane output mechanism, and a mounting plate 2. The filter membrane input mechanism and the filter membrane output mechanism are respectively connected to the mounting plate 2 via brackets 3. Specifically, the mounting plate 2 includes a first mounting plate 6 and a second mounting plate 7 arranged side-by-side, which are respectively fixed to both sides of the air vent panel via a detachable connection. Specifically, the first mounting plate 6 and the second mounting plate 7 are respectively connected to the air vent panel via connectors. These connectors can employ conventional techniques in the art, such as bolt and nut couplings, quick-locking mechanisms, snap-fit ​​connections, or pin and locking ring couplings.

[0054] The filter membrane input mechanism is connected to the first mounting plate 6 via the bracket 3, and the filter membrane output mechanism is connected to the second mounting plate 7 via the bracket 3. One end of the filter membrane 1 is connected to the filter membrane output mechanism, and it is laid out sequentially along the lower surfaces of the second mounting plate 7 and the first mounting plate 6. After being attached to the surface of the air outlet, the other end is connected to the filter membrane input mechanism. Through the interaction between the lower surfaces of the second mounting plate 7 and the first mounting plate 6 and the filter membrane 1, a guiding function is achieved, and the filter membrane 1 is kept flat and wrinkle-free.

The mounting plate 2 includes a first mounting plate 6 and a second mounting plate 7 arranged side-by-side, which are respectively fixed to both sides of an air vent panel via a detachable connection. Specifically, both the first mounting plate 6 and the second mounting plate 7 can be provided with mounting holes, and can be connected to the air vent panel via connectors. The connectors can be bolts and nuts.

[0057] The filter membrane input mechanism includes a low-speed motor 9, a first damper 10, and an input shaft 8 for winding the filter membrane 1. The low-speed motor 9 and the first damper 10 are detachably connected to both ends of the input shaft 8 and are fixedly mounted on the mounting plate 2 via a bracket 3. The filter membrane output mechanism includes a second damper 12, a third damper 13, and an output shaft 11 for winding the filter membrane 1. The second damper 12 and the third damper 13 are detachably connected to both ends of the output shaft 11 and are fixedly mounted on the mounting plate 2 via a bracket 3. Furthermore, the filter membrane input point of the filter membrane input mechanism is located above the lower surface of the first mounting plate 6, and the filter membrane output point of the filter membrane output mechanism is located above the lower surface of the second mounting plate 7.

[0058] One end of the filter membrane 1 is connected to the filter membrane output mechanism. It is laid sequentially along the lower surfaces of the second mounting plate 7 and the first mounting plate 6, and after being attached to the surface of the air outlet, the other end is connected to the filter membrane input mechanism. Through the interaction between the filter membrane 1 and the lower surfaces of the second mounting plate 7, the first mounting plate 6, and the surface of the air outlet, a guiding function can be achieved, and the filter membrane 1 can be kept flat and wrinkle-free.

[0059] The above structure allows the filter membrane 1 to adhere smoothly to the surface of the air vent, ensuring that all air passing through the vent passes through the filter membrane 1, thereby achieving effective air purification. When it is necessary to replace or clean the filter membrane 1, the second mounting plate 7 and the first mounting plate 6 can be removed without disassembling them. The old filter membrane 1 can be directly removed from the filter membrane output mechanism and the filter membrane input mechanism and replaced with a new filter membrane 1.
