Description

Technical Field

[0001] This utility model belongs to the field of filtration equipment technology, and in particular relates to a foldable filter screen and a filter module. Background Technology

[0002] With the increasing demand for air purification and water treatment, filters play a crucial role as key components in various filtration devices. Traditional filter designs are typically fixed structures, which, while ensuring stable filtration performance, consume significant space during transportation and storage and are inconvenient to handle and install. Furthermore, for certain applications requiring adaptation to filter devices of different sizes or shapes, the rigid structure of traditional filters limits their applicability and flexibility.

[0003] Therefore, how to develop a filter that can achieve simple and quick folding operation without affecting the product's lifespan and filtration performance has become a pressing technical challenge for the industry. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a foldable filter.

[0005] The objective of this utility model can be achieved through the following technical solution: a foldable filter screen, comprising:

[0006] Folding connectors;

[0007] At least two filter screen bodies are provided. The folding connector is located between two adjacent filter screen bodies and is fixed to the side of the two adjacent filter screen bodies to achieve mutual connection between the two adjacent filter screen bodies. The folding connector is made of flexible material, so that the relative angle between the two adjacent filter screen bodies can be changed through the deformation of the folding connector, thereby completing the folding or unfolding action of the filter screen bodies.

[0008] In the aforementioned foldable filter, the folding connector is made of one of the following materials: silicone rubber, polyester elastomer, leather, or textiles.

[0009] In the aforementioned foldable filter, the edges of the filter body are all provided with edging.

[0010] In one of the aforementioned foldable filters, a protective abutment layer is also provided on the side of the filter body along a direction perpendicular to the folding connector.

[0011] In the aforementioned foldable filter, the abutment protective layer and the folding connector are made of the same material and are integrally formed.

[0012] A filter module includes the aforementioned foldable filter screen and a filter screen support, wherein the foldable filter screen is assembled within the filter screen support.

[0013] In one of the above-mentioned filter modules, a plug-in limiting member is provided inside the filter support, and a plug-in limiting space is formed between the plug-in limiting member and the filter support. When the foldable filter is assembled into the filter support, the bottom of the filter body is inserted into the plug-in limiting space.

[0014] In one of the above-mentioned filter modules, the filter support is a polygon with an annular structure. The insertion limiting member includes a stop plate disposed at the bottom of the filter support. The stop plate is located within the annular space of the filter support, and the plane of the stop plate is perpendicular to the plane of the filter support. A limiting plate is fixedly disposed on the stop plate. The filter support and the limiting plate are respectively located on both sides of the stop plate, and the plane of the limiting plate is parallel to the plane of the filter support.

[0015] In one of the above-mentioned filter modules, at least two transverse movement limiting members are also fixedly installed inside the filter support. The transverse movement limiting members are distributed in a ring at intervals inside the filter support, dividing the filter installation space inside the filter support into multiple areas.

[0016] In one of the above-mentioned filter modules, the transverse limiting member includes a connecting part fixedly disposed with the filter support. The connecting part is provided with two locking parts. The length extension direction of the connecting part and the locking parts is parallel. When the foldable filter is assembled into the filter support, the connecting part abuts against the side of the corresponding filter body, and the locking parts are locked on the side of the corresponding filter body.

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

[0018] (1) By using folding connectors made of flexible materials, the angle between adjacent filter bodies can be changed freely, so that the filter as a whole has excellent folding performance, which saves space during transportation and storage, and can be quickly unfolded during use to maintain a stable structural shape. The application of flexible materials not only solves the filter folding requirements, but also takes into account the ease of operation. Users can easily complete the folding and unfolding actions. At the same time, the filter can quickly restore its original shape after unfolding, ensuring that the filtration performance is not affected, which significantly improves the practicality of the product and user satisfaction.

[0019] (2) Moreover, the folding connector in this application can be adapted to filter bodies of different materials and functions (such as odor-removing porous material layers), which can meet the folding requirements without affecting the core functions of the filter (such as adsorption and filtration), thus expanding the application scenarios of the product.

Detailed Implementation

[0026] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0027] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0028] like Figure 1 and Figure 2 As shown, a foldable filter screen includes:

[0029] Folding connector 100;

[0030] At least two filter screen bodies 200 are provided, and a folding connector 100 is located between corresponding adjacent filter screen bodies 200. The folding connector 100 is fixed to the side of the adjacent filter screen bodies 200 to achieve mutual connection between the adjacent filter screen bodies 200. The folding connector 100 is made of flexible material, so that the relative angle between the adjacent filter screen bodies 200 can be changed through the deformation of the folding connector 100, thereby completing the folding or unfolding action of the filter screen bodies 200.

[0031] In this embodiment, by using a folding connector 100 made of flexible material, the angle between adjacent filter bodies 200 can be freely changed, giving the filter excellent folding performance. This facilitates space saving during transportation and storage, and allows for quick unfolding during use while maintaining a stable structural shape. The application of flexible material not only solves the filter folding requirement but also ensures ease of operation. Users can easily complete the folding and unfolding actions, and the filter can quickly return to its original shape after unfolding, ensuring that the filtration performance is not affected. This significantly improves the practicality of the product and user satisfaction.

[0032] Furthermore, the folding connector 100 in this application can be adapted to filter bodies 200 of different materials and functions (such as odor-removing porous material layers), which can meet the folding requirements without affecting the core functions of the filter (such as adsorption and filtration), thus expanding the application scenarios of the product.

[0033] Specifically, the folding connector 100 is made of one of the following materials: silicone rubber, polyester elastomer, leather, or textiles. This not only ensures the flexibility and resilience of the filter screen during repeated folding but also prevents material fatigue or breakage caused by long-term bending, significantly extending the product's lifespan. Different materials for the folding connector 100 can be flexibly selected according to the specific needs of the filter screen. For example, silicone rubber and polyester elastomers offer high elasticity and sealing, suitable for applications requiring tight folding; leather or textiles combine flexibility and aesthetics, making them suitable for applications where aesthetics are paramount.

[0034] Preferably, the filter body 200 is provided with an edge band 201 along its edges. By providing the edge band 201 along the edges of the filter body 200, the weak parts of the filter edge are effectively reinforced, preventing cracking, delamination or wear during long-term folding or use, and significantly improving the overall structural stability and service life of the filter. It also enhances safety and comfort: the edge band 201 covers the sharp parts of the filter edge, preventing users from being scratched during use or folding, while the soft edge band 201 material further enhances the product's feel and operational comfort.

[0035] Preferably, the side of the filter body 200 is also provided with an abutment protective layer 202 along a direction perpendicular to the folding connector 100.

[0036] In this embodiment, when the foldable filter screen is assembled into the filter screen bracket 300, the abutting protective layer 202 abuts against the mounting position inside the filter screen bracket 300, which can fit tightly against the mounting position, effectively preventing the filter screen from shifting or loosening during operation, ensuring the reliability of stable assembly and long-term use; moreover, the abutting protective layer 202 provides additional buffer and support for the side of the filter screen, avoiding edge wear caused by friction or collision during installation or disassembly, and extending the service life of the filter screen.

[0037] It is worth mentioning that, in this application, as an optional solution, the abutment protective layer 202 and the folding connector 100 are disposed on the edge 201 of the corresponding filter body 200.

[0038] Preferably, the abutting protective layer 202 and the folding connector 100 are made of the same material and are integrated, which avoids structural weaknesses that may occur when splicing multiple parts. Moreover, the integrated design ensures that the flexibility of the folding connector 100 extends to the abutting protective layer 202, so that the filter screen is subjected to more even force during folding, which not only ensures flexible folding, but also avoids edge cracking or deformation caused by repeated bending.

[0039] The uniform material design makes the filter's appearance more concise and harmonious, while the material properties (such as the elasticity of silicone or the texture of leather) further enhance the product's visual and tactile experience.

[0040] A filter module includes the aforementioned foldable filter screen and a filter screen support 300, wherein the foldable filter screen is assembled within the filter screen support 300.

[0041] Preferably, the filter support 300 is provided with an insertion limiting member, and an insertion limiting space 306 is formed between the insertion limiting member and the filter support 300. When the foldable filter is assembled into the filter support 300, the bottom of the filter body 200 is inserted into the insertion limiting space 306.

[0042] More preferably, the filter support 300 is a polygon with an annular structure. The insertion limiting member includes a stop plate 301 disposed at the bottom of the filter support 300. The stop plate 301 is located within the annular space of the filter support 300, and the plane of the stop plate 301 is perpendicular to the plane of the filter support 300. A limiting plate 302 is fixedly disposed on the stop plate 301. The filter support 300 and the limiting plate 302 are respectively located on both sides of the stop plate 301, and the plane of the limiting plate 302 is parallel to the plane of the filter support 300.

[0043] In this embodiment, the polygonal bracket design can be flexibly adjusted in terms of the number of sides (such as quadrilaterals, hexagons, etc.) according to the actual installation space to adapt to different application scenarios. Through the annular polygonal filter bracket 300 and the vertically set stop plate 301, the foldable filter can be precisely positioned after assembly. The limiting plate 302 and the filter bracket 300 form an insertion limiting space 306. The bottom of the filter body 200 is inserted into the insertion limiting space 306 to realize the assembly of the foldable filter and the filter bracket 300. Precise positioning and anti-detachment design: The insertion limiting space formed by the limiting plate 302 and the filter bracket 300 provides fixation for the bottom of the filter, ensuring that the filter will not loosen under vibration or impact conditions. At the same time, the axial insertion assembly method simplifies the installation process: The "drawer-type" insertion structure allows the filter to be replaced without tools. The insertion limiting space 306 covers and protects the bottom of the filter to prevent edge damage during the loading and unloading process.

[0044] The three-dimensional limiting design (axial stop + radial limit) effectively suppresses filter screen flutter, reduces the risk of material fatigue, and significantly extends the service life of the filter module.

[0045] Preferably, at least two transverse movement limiting members 303 are also fixedly installed inside the filter support 300. The transverse movement limiting members 303 are distributed in a ring at intervals inside the filter support 300, dividing the filter installation space inside the filter support 300 into multiple areas.

[0046] In this embodiment, the filter installation space is divided into multiple independent areas by the annularly spaced lateral movement limiting members 303, so that the filter forms a grid support structure in the bracket, which effectively suppresses the lateral displacement of the filter under high-speed airflow or liquid impact, and allows users to replace the damaged filter module individually without disassembling the whole, reducing maintenance costs; while the connecting part 304 abuts against the side of the filter to achieve radial constraint, and the stop part is inserted into the side of the filter to form axial limitation, which, together with the bottom stop plate 301, constitutes an omnidirectional fixing system, completely eliminating the risk of filter shaking.

[0047] More preferably, the transverse limiting member 303 includes a connecting part 304 fixedly disposed with the filter support 300. The connecting part 304 is provided with two locking parts 305. The length extension direction of the connecting part 304 and the locking parts 305 are parallel. When the foldable filter is assembled into the filter support 300, the connecting part 304 abuts against the side of the corresponding filter body 200, and the locking parts 305 are locked on the side of the corresponding filter body 200.

[0048] In this embodiment, the connecting part 304 fits tightly against the side of the filter screen, and together with the precise positioning of the blocking part 305, a double constraint structure is formed to ensure that the filter screen remains stable and does not shift during operation. The parallel-arranged blocking parts 305 not only provide a reliable limiting function, but also effectively buffer vibration and impact, so that the filter screen remains stable under dynamic working conditions, retaining the effective filtration area of ​​the filter screen to the maximum extent and significantly reducing airflow resistance.

[0049] The combination of the retaining part 305 and the connecting part 304 forms a guiding structure, allowing users to complete the installation simply by pushing the filter screen in axially. Disassembly is performed by reversing the operation, simplifying the maintenance process.

[0050] It is worth mentioning that the abutment protection layer 202 on the filter body 200 extends to cover the side, so that the filter body 200 located in the insertion limiting space can be wrapped by the abutment protection layer 202.
