[0023] The following examples provide a more detailed description of the features and other related characteristics of this utility model, to facilitate understanding by those skilled in the art:

[0024] For ease of description and understanding, please refer to the directions shown in the attached diagram for descriptions related to positional relationships such as front, back, top, bottom, left, right, outside, and inside in this case.

[0025] like Figure 1 , Figure 5 , Figure 6As shown, existing drain filter screens 200 generally include a protrusion 202 for easy handling by the user, allowing the user to replace the drain filter screen 200. This is existing technology. Especially with the increasing use of disposable drain filter screens 200 to replace traditional drain filter screens in the home furnishing industry, frequent replacement of drain filter screens is necessary. The drain filter screen replacement device of this invention is particularly suitable for replacing disposable drain filter screens 200.

[0026] like Figures 1 to 6 As shown, this invention provides a device for replacing a drain filter, including a housing 1. The housing 1 is the main frame of the device, providing structural support for the entire device, protecting the internal components from external interference, and facilitating handheld operation by the user. A flexible material receiving channel 2 is provided at the lower end of the housing 1, and the material receiving channel 2 has an internally hollow structure. In specific implementation, the upper end of the material receiving channel 2 is adapted to the lower end of the connecting rod 3, facilitating the insertion and passage of the connecting rod 3; the lower end is tapered, adapting to the protrusions 202 on most drain filters 200 on the market, and possesses flexible deformation characteristics. The flexible deformation design makes the gripping of the drain filter 200 more secure, preventing the drain filter 200 from falling. The material receiving channel 2, through its flexible deformation, wraps around the head of the drain filter 200, achieving the gripping of the drain filter 200, while simultaneously providing a movement channel for the connecting rod 3, which, in conjunction with the connecting rod 3, pushes the drain filter 200 out of the material receiving channel 2. A connecting rod 3 is installed inside the housing 1, with its lower end inserted into the receiving channel 2. The housing 1 also has a button 5 for driving the connecting rod 3 to extend and retract within the receiving channel 2. Specifically, the connecting rod 3 is a rod-shaped structure, its lower end inserted into the receiving channel 2, adapting to the internal space of the channel and allowing it to extend and retract freely within it. Driven by the button 5, the connecting rod 3 can extend and retract within the receiving channel 2. When moving downwards, it pushes out the protrusion 202 of the drain filter 200 wrapped within the receiving channel 2, thus releasing the drain filter 200 and preventing direct contact with the drain filter 200, keeping hands clean. The button 5 serves as the driving component, allowing the user to directly control the extension and retraction of the connecting rod 3 within the receiving channel 2 by pressing the button 5, providing a convenient operation method. The user can easily control the release of the drain filter 200. The connecting rod 3 is elastically connected to the housing 1 via an elastic element 4. The elastic element 4 is configured to provide elastic restoring force to the connecting rod 3, allowing the connecting rod 3 to remain in its initial position when no external force is applied (i.e., when the button 5 is not pressed). This ensures the continuity and stability of the device's operation, allowing the connecting rod 3 to automatically reset after the user presses the button 5 to push out the drain filter 200, and after the user releases the button 5, making it convenient for the next use.

[0027] In use, the user holds the housing 1, aligns the receiving channel 2 with the protrusion 202 of the drain filter 200, and applies pressure to the receiving channel 2, causing it to elastically deform so that the receiving channel 2 completely wraps around the protrusion 202 of the drain filter 200. Then, the user lifts the housing 1. Because the receiving channel 2 tightly wraps around the protrusion 202 of the drain filter 200, the drain filter 200 will be lifted along with the housing 1, completing the grasping operation of the drain filter 200. After the user moves the grasped drain filter 200 to the trash can or flushing area, they press button 5. Button 5 drives the connecting rod 3 to overcome the elastic force of the elastic element 4, and the lower end of the connecting rod 3 moves downward along the receiving channel 2. The connecting rod 3 presses downward against the protrusion 202 of the drain filter 200 until the protrusion 202 of the drain filter 200 is completely pushed out of the receiving channel 2, completing the release operation of the drain filter 200. When the user releases button 5, the elastic force of the elastic element 4 causes the linkage 3 to return to its initial position, preparing it for the next use.

[0028] Furthermore, such as Figures 1-3 , Figure 5 , Figure 6 As shown, the connecting rod 3 includes a baffle 31, and the housing 1 has a first blocking surface 11 for preventing the connecting rod 3 from rising excessively. When the upper end of the baffle 31 abuts against the first blocking surface 11, the connecting rod 3 rises to its designated position. In specific implementations, the baffle 31 is a plate-shaped structure perpendicular to the body of the connecting rod 3, and the two are integrally formed. The first blocking surface 11 serves as a limiting structure for the rising of the connecting rod 3. When the baffle 31 rises to abut against the first blocking surface 11, it prevents the connecting rod 3 from continuing to rise, thus determining the limit position of the rising of the connecting rod 3. This provides a clear limit for the rising of the connecting rod 3, ensuring the normal working sequence of the device. By precisely controlling the rising position of the connecting rod 3, the device can return to a stable initial state after each use, improving the reusability and operational accuracy of the device.

[0029] Continue to refer to Figures 1-3 , Figure 5 , Figure 6As shown, in this embodiment, the housing 1 includes a first housing 101 and a second housing 102 that are interlocked. Hooks 1011 are symmetrically arranged on both sides of the first housing 101, and slots 1021 for the hooks 1011 to engage are symmetrically arranged on both sides of the second housing 102. Positioning plates 1012 are also symmetrically arranged on both sides of the first housing 101, and positioning grooves 1022 for the positioning plates 1012 to engage are symmetrically arranged on both sides of the second housing 102. This design uses a first housing 101 and a second housing 102 that are easily disassembled to facilitate internal maintenance and replacement by the user. In specific implementation, to ensure a more stable connection between the first housing 101 and the second housing 102, two sets of hooks 1011 and slots 1021 are provided, as are two sets of positioning plates 1012 and positioning grooves 1022. The hook 1011 and the slot 1021 cooperate to provide the main connection and fixation for the first housing 101 and the second housing 102, ensuring a tight connection that is not easily separated. The snap-fit ​​method of the hook 1011 and the slot 1021 is simple and reliable, facilitating disassembly and assembly while ensuring connection stability. The two sets of hooks 1011 and slots 1021 further enhance the connection stability, enabling housing 1 to withstand certain external forces without separation. The positioning plate 1012 and the positioning groove 1022 cooperate to provide positioning and auxiliary fixation. During assembly, the positioning plate 1012 first snaps into the positioning groove 1022, providing positioning for the hook 1011 to accurately snap into the slot 1021, ensuring precise docking of the first housing 101 and the second housing 102. The positioning plate 1012 and the positioning groove 1022 improve the accuracy and efficiency of housing 1 assembly, while also assisting the hooks 1011 and the slots 1021 in enhancing connection stability.

[0030] Specifically, such as Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, the elastic element 4 in this case is a telescopic spring. The upper end of the telescopic spring is connected to the inside of the housing 1, and the lower end is connected to the connecting rod 3. As the core transmission component, the telescopic spring establishes an elastic connection between the housing 1 and the connecting rod 3. The upper end of the telescopic spring is connected to the inside of the housing 1, forming a fixed fulcrum; the lower end of the spring is fixed to the connecting rod 3 and can be compressed or stretched as the connecting rod 3 moves up and down. This connection ensures that the telescopic movement of the connecting rod 3 is always constrained by the elastic force of the telescopic spring, forming a linkage with the drive of the button 5, ensuring stable mechanical feedback during the grabbing and releasing of the drain filter 200 by the device in this case.

[0031] like Figures 1-6As shown, a connecting hole 32 is further provided on the connecting rod 3. The button 5 includes a pressing end 51 and a connecting end 52, with the connecting end 52 movably connected to the connecting hole 32. The connection hole 32 enables an effective connection between the button 5 and the connecting rod 3, allowing the movement of the button 5 to be transmitted to the connecting rod 3. This ensures that when the user presses the button 5, the pressing end 51 can move within the connecting hole 32, thereby accurately driving the connecting rod 3 and improving the operational accuracy and reliability of the device. In a specific implementation, the connecting hole 32 is a vertically arranged rectangular hole. A mounting hole 13 is provided on the housing 1, and the button 31 is installed in the mounting hole 13 and exposed outside the housing 1. The mounting hole 13 provides an installation position for the button 5, ensuring that the button 5 can be accurately installed on the housing 1 and exposed outside the housing 1, facilitating user operation. The housing 1 also provides an extension plate 14 for supporting and limiting the connecting end 52. In a specific implementation, two extension plates 14 are symmetrically arranged vertically. The extension plate 14 supports and limits the connection end 52 of the button 5. The limiting function of the extension plate 14 ensures that the button 5 can accurately drive the linkage 3 to move, and ensures that the button 5 will not deviate or shake during the movement, thereby improving the stability and accuracy of the movement of the button 5.

[0032] Furthermore, such as Figure 1 , Figure 2 , Figures 4-6As shown, the connecting end 52 includes a downwardly inclined first slope 521, a first step 522 connected to the lower end of the first slope 521, and a blocking surface 523 connected to the right end of the first step 522. The lower end of the connecting hole 32 is provided with a second slope 321 that abuts against the first slope 521. The first slope 521 and the second slope 321 have the same inclination angle. The first slope 521 is located on the upper section of the connecting end 52 of the button 5 and is downwardly inclined; the second slope 321 is located at the lower end of the connecting hole 32 of the connecting rod 3, and both have the same inclination angle. In specific implementation, the surfaces of both the first slope 521 and the second slope 321 are smooth, preferably designed with a 45° inclination angle, forming a symmetrical V-shaped guide groove structure. When the user presses button 5, the inclined surface 521 with the same tilt angle and the second inclined surface 321 always remain in contact, which can automatically correct the alignment deviation between the connecting end 52 and the connecting hole 32. At the same time, the pressing force of the user pressing button 5 is evenly distributed into vertical and horizontal components through the double inclined surfaces, so that the connecting end 52 slides smoothly along the inclined surfaces, making the pressing smoother and more stable, and making the extension and retraction of the connecting rod 3 more stable. When the first step 522 is fully inserted into the connecting hole 32, the downward stroke of the connecting rod 3 is clearly defined, so that the connecting rod 3 reaches the predetermined downward pressing position, ensuring that appropriate top pressure is applied to the protrusion 202 of the drain filter 200. The first step 522, as the main force transmission interface, evenly transmits the pressing force of button 5 to the connecting rod 3, avoiding cracks at the edge of the connecting hole 32 due to single-point force. When button 5 is pressed to its limit position, the blocking surface 523 and the outer wall of the connecting hole 32 (i.e., the connecting rod 3) form a mechanical hard limit, effectively preventing excessive pressing of button 5. In specific implementation, there are two blocking surfaces 523 symmetrically arranged vertically. In this case, the cooperation between the first step 522 and the blocking surface 523 can effectively prevent the connecting rod 3 from being excessively pressed. The geometric constraints of the double inclined surfaces 521 and 321, the stroke limit of the first step 522, and the hard protection of the blocking surface 523 together construct a three-level fault protection mechanism. The first inclined surface 521 and the second inclined surface 321 effectively prevent alignment deviation, the first step 522 precisely controls the standard stroke, and the blocking surface 523 prevents overtravel damage, providing comprehensive protection for the stable operation of the device.

[0033] Furthermore, this is a preferred embodiment of the present invention. In this embodiment, an elastic colloid connector 6 is also provided inside the housing 1. The elastic colloid connector 6 is fixed inside the housing 1 by a fixing seat 7, and the receiving channel 2 is opened on the elastic colloid connector 6. In specific implementation, the elastic colloid connector 6 is made of an elastic colloid material, such as silicone, which has good flexibility, corrosion resistance, and sealing performance. The shape and size of the elastic colloid connector 6 are adapted to the internal structure of the device and can fit tightly with other components. The corrosion resistance of silicone allows the elastic colloid connector 6 to be used for a long time in humid, watery bathroom environments where chemicals may be present, without being easily damaged. The good flexibility of silicone can also adapt to drain filters of different shapes and sizes, improving the versatility of the device. The fixing seat 7 is usually made of a rigid material, such as plastic or metal, with a certain strength and stability. The main function of the fixing seat 7 is to firmly fix the elastic colloid connector 6 inside the housing 1, preventing the elastic colloid connector 6 from shifting or shaking during the use of the device, ensuring the stability of the receiving channel 2, and improving the operating accuracy and reliability of the device.

[0034] Furthermore, such as Figures 1-6 As shown, a handle 8 is detachably connected to the upper end of the housing 1. The handle 8 has a hollow internal structure. This hollow internal structure of the handle 8 reduces its weight and facilitates the insertion of the connecting rod 15. The handle 8 is the part held by the user when operating the device, providing a comfortable grip experience. The detachable connection with the housing 1 allows users to easily replace handles of different lengths, sizes, or shapes according to their actual needs. Users can change the handle themselves based on the usage scenario and their own needs, such as when they need to extend the operating distance or replace it with a handle that better suits their hand grip habits. This design improves the applicability of the device and the user experience. The housing 1 includes a connecting rod 15 that is inserted into and connected to the handle 8. A protrusion 151 extends longitudinally on the outer wall of the connecting rod 15, and a groove 81 is formed on the inner wall of the handle 8 for the protrusion 151 to be inserted. The groove 81 on the inner wall of the handle 8 extends longitudinally along the handle 8 and its size is adapted to the protrusion 151. The connecting rod 15 serves as a bridge connecting the housing 1 and the handle 8. Through the engagement of the protrusion 151 with the groove 81 on the inner wall of the handle 8, the handle 8 is fixed to the housing 1, ensuring the overall stability of the device. This connection method not only ensures the firmness of the connection between the handle 8 and the housing 1 but also facilitates disassembly and installation, making the replacement of the handle 8 simple and easy.

[0035] like Figure 1As shown, preferably, the drain filter replacement device of this invention also includes a base 9, with the housing 1 inserted into the base 9. The base 9 has drainage holes at its bottom, and a backing sticker 91 is attached to its back. The base 9 provides a dedicated storage space for the device, and the backing sticker 91 helps to fix the device in a suitable position, preventing it from being placed randomly and making storage more organized and convenient for users when not in use. The drainage holes effectively solve the problem of residual water after use, allowing for timely and effective drainage, preventing water damage to the device, and extending its service life.

[0036] This invention also provides a structure for replacing a floor drain filter, including the device for replacing the floor drain filter described in this invention, and a floor drain screen 200. The floor drain screen 200 includes a screen portion 201 and a protrusion portion 202. The protrusion portion 202 has an annular rib 2021 on its outer ring, and an annular groove 21 that fits and limits the annular rib 2021 is opened inside the receiving channel 2. The annular rib 2021 surrounds the outer ring of the protrusion portion 202 and has a certain height and width; the annular groove 21 is opened inside the receiving channel 2, and its shape and size are adapted to the annular rib 2021, so as to tightly accommodate the annular rib 2021. With the limiting cooperation of the annular rib 2021 and the annular groove 21, when the protrusion 202 is inserted into the receiving channel 2, the annular rib 2021 is engaged in the annular groove 21, preventing the drain screen 200 from shaking or falling off during the operation of the device, ensuring the stability of the gripping, improving the stability and reliability of the device in gripping the drain screen 200, reducing the risk of the drain screen falling off during the operation, and increasing the success rate of replacing the filter screen.

[0037] As stated above, this case protects a device for replacing a drain filter and the structure for replacing the drain filter. All technical solutions that are identical or similar to this case should be considered to fall within the scope of protection of this case.
