[0022] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0023] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0025] Embodiments of this utility model provide an easy-to-disassemble filter screen, such as... Figure 1-3 As shown, it includes:

[0026] Filter frame 1;

[0027] Filter cotton 2 is detachably installed on filter frame 1;

[0028] The support structure 3 is mounted on the filter frame 1. The support structure 3 is used to support the filter cotton 2. The support structure 3 includes a first support rod 301 and a second support rod 302 arranged at intervals. The first support rod 301 is used to support and fix the filter cotton 2 in a first direction, and the second support rod 302 is used to support and fix the filter cotton 2 in a second direction.

[0029] In this embodiment, the first support rod 301 and the second support rod 302, arranged at intervals, respectively support and fix the filter cotton 2 to the left and right sides. Furthermore, the support rods can be adjusted in the corresponding direction according to the required support direction. The support rod type support structure 3 is simple, and the two work together to provide good support. Through staggered support, the filter cotton 2 forms multiple peaks and troughs, making the filter cotton 2 form a W-shaped structure as shown in this embodiment, which significantly increases the surface area of ​​the filter cotton 2, thereby improving the filtration efficiency. The filter cotton 2 is fixed by the clamping support structure 3, so that the filter cotton 2 can be detachably installed on the filter frame 1. The filter cotton 2 can be removed from the frame and only the filter cotton 2 needs to be replaced. The filter cotton 2 is inexpensive, has a good filtration effect, is durable, and has low replacement cost.

[0030] In some embodiments, such as Figure 2 As shown, both the first support rod 301 and the second support rod 302 include a support part 303 for supporting the filter cotton 2 and a fixing part 304 for connecting with the filter frame 1.

[0031] The support part 303 effectively supports the filter cotton 2, ensuring it is flat and fixed on the frame, preventing a decrease in filtration efficiency due to wrinkles or loosening; the fixing part 304 is connected to the filter frame 1, improving the stability of the support part 303. The fixing part 304 can be a structure such as a buckle, insert, or clamp that is provided on both sides of the support part 303 and can be inserted into or clamped by the filter frame 1; furthermore, the fixing part 304 can also be a frame that connects and fixes each support part 303.

[0032] Furthermore, such as Figure 1-2 As shown, the support portions 303 of the first support rod 301 and the second support rod 302 are both "U" shaped. The opening of the support portion 303 of the first support rod 301 faces the second direction, and the opening of the support portion 303 of the second support rod 302 faces the first direction.

[0033] The support parts 303 of the first support rod 301 and the second support rod 302 are both "U"-shaped with bottom horizontal bars and no horizontal bars at the top opening. The opening directions of the support parts 303 of the first support rod 301 and the second support rod 302 are opposite, which can stagger and evenly and stably support the filter cotton 2, ensuring that the filter cotton 2 forms a W-shaped shape within the frame. The "U"-shaped opening design means that the filter screen does not have many additional frames, maintaining the support effect while ensuring good frame concealment, reducing usage costs, and facilitating quick installation and removal of the filter cotton 2.

[0034] Furthermore, such as Figure 3 As shown, the fixing part 304 of the first support rod 301 includes a first fixing frame 305 for connecting and fixing each support part 303 of the first support rod 301, and the fixing part 304 of the second support rod 302 includes a second fixing frame 306 for connecting and fixing each support part 303 of the second support rod 302.

[0035] The fixing part 304 of the first support rod 301 connects and fixes each support part 303 of the first support rod 301 through the first fixing frame 305. The fixing part 304 of the second support rod 302 achieves the same function through the second fixing frame 306, which makes the overall shape of the support part 303 better and enhances the stability and reliability of the entire filter screen. The design of the fixing frame facilitates the quick connection and disassembly of the first support rod 301 and the second support rod 302 with the side frame of the filter screen frame 1, improving the assembly and maintenance efficiency of the filter screen.

[0036] In some embodiments, such as Figure 2 As shown, an easy-to-disassemble filter screen further includes: a quick-release and quick-install structure 4 disposed on the filter screen frame 1, the quick-release and quick-install structure 4 being used to fix and disassemble the filter screen frame 1.

[0037] The quick-release and quick-install structure 4 eliminates the need for screws or other complicated tools, allowing users to easily install and remove the filter by hand, greatly improving maintenance efficiency and saving time and effort.

[0038] Furthermore, such as Figure 3 As shown, the quick-release and quick-install structure 4 includes a first buckle 401 and a second buckle 402, which are arranged opposite to each other on the upper and lower or left and right sides of the filter frame 1.

[0039] The first clip 401 and the second clip 402 are fixed in place by snapping into the corresponding interface or slot on the device, which enables quick fixing and disassembly of the filter screen, thus achieving a fixed installation of the filter screen.

[0040] In this embodiment, the first buckle 401 and the second buckle 402 are respectively disposed at the top and bottom of the filter frame 1.

[0041] Furthermore, such as Figure 3 As shown, the first latch 401 and / or the second latch 402 include a latch block 403, a sliding block 404 connected to the latch block 403 and slidable relative to the filter frame 1, and a limiting structure 405 that can restrict the movement of the sliding block 404. The sliding block 404 can fix or release the filter frame 1 by moving the latch block 403.

[0042] The sliding block 404 allows the latching block 403 to slide in the up, down, left, and right directions, enabling it to engage with or disengage from the corresponding interface or slot on the device. The limiting structure 405, such as a top block, spring, or protrusion, effectively restricts the movement of the sliding block 404, preventing it from loosening or shifting due to accidental vibration or external force during use, thus ensuring the stability and reliability of the latching structure. In this embodiment, the first latch 401 includes a latching block 403, a sliding block 404, and a limiting structure 405. The second latch 402 is the latching block 403. The second latch 402 is first inserted into the corresponding groove on the device, while the first latch 401 is inserted by first pressing down the sliding block 404 and then engaging the latching block 403 into the corresponding groove on the device, thereby achieving installation and fixation. Further, both the first latch 401 and the second latch 402 may include a latching block 403, a sliding block 404, and a limiting structure 405.

[0043] Furthermore, such as Figure 3 As shown, the limiting structure 405 includes a spring disposed on one side of the sliding block 404.

[0044] The spring has excellent elastic recovery function, providing stable support and automatic reset for the sliding block 404. The direction of the spring is determined by the installation direction of the latching block 403, as shown in this embodiment. When the first latch 401 needs to be installed, the user can press the sliding block 404 to compress the spring, facilitating the latching block 403 to snap into the corresponding interface or slot on the device. After installation, the spring automatically returns the sliding block 404 to its initial position, ensuring that the latching block 403 always remains in the correct working position, thereby improving the stability and reliability of the latching structure.

[0045] In some embodiments, such as Figure 3 As shown, the latching block 403 is L-shaped, and one end of the sliding block 404 is connected to the latching block 403, while the other end protrudes outward from the filter frame 1.

[0046] The L-shaped snap-fit ​​block 403 has a simple structure and is easy to install and fit. During installation, it can be easily embedded into the corresponding slot. The sliding block 404 protrudes from the filter frame 1, allowing the user to easily move the sliding block 404. The other end is connected to the snap-fit ​​block 403, which can control the movement of the snap-fit ​​block 403 to achieve quick installation and removal of the snap-fit.
