[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0025] Please refer to Figs. 1-3 The present application provides a technical solution: a kitchen sink filter, which comprises a sink body 10 and an L-shaped drain pipe 11 connected to the drain opening of the sink body 10, the L-shaped drain pipe 11 comprising a vertical section and a horizontal section, for guiding the liquid in the sink to the municipal drainage system; further comprising a filter basket 12, a protection shell 13, a filter screen 14 and a top cover 15.
[0026] Furthermore, the filter basket 12 is made of stainless steel or corrosion-resistant engineering plastic, the upper end of the filter basket 12 is cup-shaped, the lower end is cylindrical, the upper part of the filter basket 12 is open, the filter basket 12 is designed to be placed into the drain opening of the sink body 10, and the cylindrical lower end extends downward, partially extending into the vertical section of the L-shaped drain pipe 11, the filter basket 12 is used to receive the liquid mixed with solid impurities flowing from the sink.
[0027] Further, inside the filter basket 12, a detachable filter screen 14 is installed, which can effectively intercept food residues, tea leaves, hair and other solid impurities of larger size, while allowing liquid to pass through. The filter screen 14 is made of stainless steel mesh, nylon mesh or other suitable filter material.
[0028] Further, the filter basket 12 and the protective shell 13 sleeved on the outer peripheral wall thereof are in sliding connection. The protective shell 13 is a hollow cylindrical structure, and its inner diameter is slightly larger than the outer diameter of the filter basket 12, so that the filter basket 12 can slide axially inside the protective shell 13. The bottom of the protective shell 13 can be in contact with the inner cavity bottom wall of the vertical section of the L-shaped drain pipe 11, so that the protective shell 13 can be stably positioned at the lowest position under the action of gravity.
[0029] When the protective shell 13 is at the lowest position, a specific space is formed between the inner wall of the protective shell 13 and the outer wall of the filter basket 12, which is a liquid discharge channel. The bottom surface and the lower part of the outer peripheral wall of the filter basket 12 are provided with a plurality of circular holes 121 for liquid to pass through. When sewage enters the filter basket 12, the liquid passes through the filter screen 14 and the circular holes 121, flows into the space between the filter basket 12 and the protective shell 13, and finally communicates with the horizontal section of the L-shaped drain pipe 11 through the space, so as to be smoothly discharged.
[0030] Further, in order to realize the sliding connection between the filter basket 12 and the protective shell 13, at least two T-shaped sliding blocks 122 are fixed on the outer wall of the filter basket 12, and at least two strip-shaped protruding columns 131 corresponding in number and position to the T-shaped sliding blocks 122 are arranged on the top of the protective shell 13.
[0031] A long strip-shaped T-shaped sliding groove 132 extending along the length direction is formed on each strip-shaped protruding column 131. The T-shaped sliding blocks 122 on the filter basket 12 can be embedded into the corresponding T-shaped sliding grooves 132 on the protective shell 13 and can slide in the T-shaped sliding grooves 132.
[0032] The cooperation of the T-shaped sliding blocks 122 and the T-shaped sliding grooves 132 not only guides the sliding direction and prevents shaking, but also prevents the filter basket 12 from accidentally coming out of the protective shell 13.
[0033] Further, a top cover 15 is installed at the top opening of the filter basket 12. The top cover 15 covers the filter basket 12 to prevent odor emission and facilitates the user to lift the filter basket 12.
[0034] The top cover 15 is detachably fixed at the top opening of the filter basket 12 by magnetic force. Specifically, an attractive permanent magnet or magnet and ferromagnetic material are arranged on the inner side of the edge of the top cover 15 and the upper opening edge of the filter basket 12. The top cover 15 can be firmly attracted to the filter basket 12, and at the same time, the user can easily exert a certain force to remove it.
[0035] Further, the top cover 15 is further provided with a drain hole 151 with a filter screen, the drain hole 151 is small in size, and the outer surface of the top cover 15 is further provided with a sealing assembly for selectively sealing the drain hole 151.
[0036] The sealing assembly comprises a connecting rope 16, one end of the connecting rope 16 is fixed to the top cover 15, for example, by passing through a small hole and knotting, or by adhesive, and the other end of the connecting rope 16 is fixed with a plug 17, the plug 17 is matched with the drain hole 151 in shape and size, and is made of elastic material such as silica gel or rubber, and can effectively seal the drain hole 151, and the plug 17 is inserted into the drain hole 151 in normal time to prevent odor and insects.
[0037] Working steps:
[0038] Normal filtering state:
[0039] The filter basket 12 is sleeved in the protection shell 13, the top cover 15 is covered on the filter basket 12, the plug 17 seals the drain hole 151, and the filter basket 12 is placed at the drain port of the sink body 10, the protection shell 13 will slide downward along the outer periphery of the filter basket 12 under the action of gravity until the bottom of the protection shell 13 is in contact with the bottom wall of the inner cavity of the vertical segment of the L-shaped drain pipe 11, and in this state, the round holes 121 on the filter basket 12 are exposed.
[0040] When sewage containing solid impurities flows from the sink into the filter basket 12, the larger solid impurities are intercepted by the inner filter screen 14 and remain in the filter basket 12, and the liquid passes through the filter screen 14 and then flows into the drain space formed between the filter basket 12 and the protection shell 13 through the round holes 121 of the filter basket 12, and finally flows into the horizontal segment of the L-shaped drain pipe 11 and is discharged.
[0041] Cleaning waste state:
[0042] When a large amount of solid impurities are accumulated in the filter basket 12 and need to be cleaned, the user holds the top cover 15, and due to the magnetic force, lifting the top cover 15 will simultaneously lift the filter basket 12, the entire filter basket 12 is lifted together with the top cover 15 upward, so that the filter basket 12 is separated from the drain port of the sink and the L-shaped drain pipe 11, and then the filter basket 12 is laid flat with the protection shell 13, and the water remaining between the filter basket 12 and the protection shell 13 is discharged.
[0043] Then, the user manually slides the protection shell 13 upward along the outer periphery of the filter basket 12, and when the protection shell 13 is slid upward to a certain position, the cylindrical wall of the protection shell 13 will cover and close the round holes 121 on the filter basket 12, which can effectively prevent the sewage and small impurities remaining in the filter basket 12 from overflowing from the round holes 121 during the movement and dumping of the solid waste in the filter basket 12, and avoids secondary pollution and cleaning trouble.
[0044] After the round hole 121 is closed by the protective shell 13, there is still some water above the solid impurities in the filter basket 12, at this time, the user removes the plug 17 on the top cover 15, opens the drain hole 151, and since the drain hole 151 is provided with a filter screen, the residual liquid can be drained from the drain hole 151, further reducing the amount of liquid when pouring the solid waste subsequently.
[0045] Finally, the solid impurities in the filter basket 12 are poured into the garbage can.
[0046] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
