[0022] The technical solutions in the utility model will be further described below with reference to the drawings and embodiments.

[0023] As Figure 1As shown in the figure, an embodiment of the present utility model provides a kitchen sink filter, including:

[0024] A first filter cartridge 1, having a channel penetrating through both ends thereof, and provided with a plurality of first filter holes 101 for filtering debris;

[0025] A cover plate 3, fastened to one end of the channel. A connecting rod 4 is slidably provided inside the first filter cartridge 1 along its axis, and the connecting rod 4 is connected to the cover plate 3. When the cover plate 3 slides along the axis of the first filter cartridge 1, it drives the cover plate 3 to fasten to the channel to close it, or separate from the channel to open it.

[0026] In an embodiment of the present utility model, the first filter cartridge 1 is of a cylindrical structure, and both ends are penetrated to form a channel. When the first filter cartridge 1 and the installed cover plate 3 are installed in the sink for use, by lifting the connecting rod 4 connected to the cover plate 3, the connecting rod 4 drives the cover plate 3 to fasten to the end of the channel of the first filter cartridge 1, so that the channel forms a closed space for carrying debris, allowing water to be discharged through a plurality of first filter holes 101 of the first filter cartridge 1, and the debris stays in the first filter cartridge 1, preventing the debris from entering the sewer.

[0027] Secondly, when dealing with the debris, by pressing the connecting rod 4, the connecting rod 4 drives the cover plate 3 to separate from the channel end, opening the channel, so that the debris located in the first filter cartridge 1 leaves the first filter cartridge 1. And when cleaning the first filter cartridge 1, since both ends of the first filter cartridge 1 are penetrated, the debris attached to the inner wall of the first filter cartridge 1 can be directly discharged from the bottom of the channel by the impact of water flow, leaving no debris residue inside the first filter cartridge 1, improving the convenience of cleaning the first filter cartridge 1 and ensuring the cleanliness of the first filter cartridge 1 after cleaning.

[0028] Specifically, as Figure 1 As Figure 4 shown, an installation cylinder 7 is fixedly provided inside the first filter cartridge 1. A spring 6 is provided inside the installation cylinder 7. The connecting rod 4 passes through the spring 6 and is connected to the cover plate 3. A pressing block 401 connected to the connecting rod 4 is also provided inside the installation cylinder 7, and the pressing block 401 abuts against the top end of the spring 6.

[0029] In the initial state, the spring 6 is in a normal stretched state inside the installation cylinder 7, causing the pressing block 401 to be squeezed by the spring 6 and located at the top of the installation cylinder 7, so that the cover plate 3 is fastened to the channel end (the bottom of the first filter cartridge 1) in the initial state. When opening the cover plate 3, by continuously pressing the connecting rod 4, the pressing block 401 moves downward to squeeze the spring 6 to deform it. When the debris in the first filter cartridge 1 is cleaned up and the first filter cartridge 1 is cleaned, the connecting rod 4 is directly released, and under the reset of the spring 6, the cover plate 3 is driven to fasten to the channel end again for convenient subsequent reuse.

[0030] Specifically, asFigure 1 As shown, a limit block 5 is fixedly arranged at the top end of the connecting rod 4; under the action of the limit block 5, the contact area between the end of the connecting rod 4 and the finger can be increased, which is convenient for operating the connecting rod 4.

[0031] Based on the above solution, as Figures 1 to 4 shown, it further includes a second filter cartridge 2. The second filter cartridge 2 is provided with a plurality of second filter holes 201 corresponding to a plurality of first filter holes 101, and the second filter cartridge 2 is sleeved on the first filter cartridge 1. The first filter cartridge 1 is provided with an annular block 104, and the first filter cartridge 1 is provided with an annular groove 203. The first filter cartridge 1 is clamped in the annular groove 203 through the annular block 104.

[0032] Through the cooperation of the first filter cartridge 1 and the second filter cartridge 2, in the filtering state, a plurality of first filter holes 101 of the first filter cartridge 1 correspond to a plurality of second filter holes 201 of the second filter cartridge 2 one by one, so that the first filter cartridge 1 and the second filter cartridge 2 form a permeable structure for filtering. When it is necessary to collect the water in the water tank, the first filter cartridge 1 can be rotated, so that the first filter holes 101 of the first filter cartridge 1 are circumferentially offset, so that the first filter holes 101 of the first filter cartridge 1 are blocked by the second filter cartridge 2, thereby realizing the blocking of the water outlet of the water tank and facilitating use.

[0033] Specifically, as Figure 3 shown, a slider 102 is fixedly arranged on the top end surface of the first filter cartridge 1, and the slider 102 is provided with a plurality of anti-slip strips 103; with the cooperation of the slider 102, the top end of the first filter cartridge 1 protrudes to the surface of the second filter cartridge 2, which is convenient for rotating and adjusting the first filter cartridge 1, and the friction between the slider 102 and the finger is increased under the action of the plurality of anti-slip strips 103.

[0034] Specifically, as Figure 2 shown, the second filter cartridge 2 is provided with a first clamping block 204 and a second clamping block 205, and the slider 102 is located between the first clamping block 204 and the second clamping block 205; with the cooperation of the first clamping block 204 and the second clamping block 205, the slider 102 can be limited. Among them, when the slider 102 abuts against the first clamping block 204, a plurality of first filter holes 101 of the first filter cartridge 1 correspond to a plurality of second filter holes 201 of the second filter cartridge 2 one by one. When the slider 102 abuts against the second clamping block 205, a plurality of first filter holes 101 of the first filter cartridge 1 are separated from a plurality of second filter holes 201 of the second filter cartridge 2, effectively avoiding excessive movement.

[0035] Specifically, as Figure 2 shown, a sealing strip 202 is arranged at the top end of the second filter cartridge 2; the sealing performance between the second filter cartridge 2 and the water outlet of the water tank can be increased, and the water storage efficiency in the water tank can be guaranteed.

[0036] Specifically, as Figure 3As shown, the cover plate 3 is provided with a boss 301, and the boss 301 is buckled to the end of the channel; under the action of the boss 301, when the cover plate 3 is buckled to the end of the first filter cartridge 1, the boss 301 is buckled to the end of the channel, increasing the connection area between the cover plate 3 and the first filter cartridge 1 and improving the sealing performance.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
