It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0030] In the drawings, the same reference numerals all refer to the same components.
[0031] Example 1
[0032] Reference Figure 1-10The utility model provides an embodiment: a floor drain core with anti-blocking, filtering and odor-proof function, comprising a floor drain core body 1, a holder 2 is installed at one end of the floor drain core body 1, a drain valve body 3 is installed at the bottom end of the holder 2, a metal block 4 is installed at the bottom end of the drain valve body 3, a flap 5 is installed at the bottom end of the metal block 4, a filter screen 6 is installed at the bottom end of the holder 2, a sealing ring 301 is installed at the top end of the drain valve body 3, and two positioning holes 302 are installed on the surface of the drain valve body 3.
[0033] Furthermore, the flap 5 includes a boss 501, a protrusion 502 is installed on one side of the boss 501, a cavity 503 is arranged on the inner side of the flap 5, and a plurality of welding points 601 are arranged on the top side surface of the filter screen 6 for limiting the position during flipping to prevent excessive water impact force and the flap 5 from being unable to reset when it rotates to the gravity balance point.
[0034] The base 2 is in the shape of a stepped ring, with a stepped through hole in the middle for accommodating the drain valve body, and the annular surfaces at the other steps are the contact surfaces of the sealing ring; an annular groove is provided on the top side of the drain valve body 3 for compressing and fixing the drain valve body 3 and sealing to prevent water overflow, and the tapered opening at the bottom is used to connect the filter 6.
[0035] The drain valve body 3 is connected to the base 2 through an annular groove and a sealing ring 301; a drainage channel is provided in the middle of the drain valve body 3, the drainage channel is wide at the top and narrow at the bottom, and symmetrical positioning holes are provided on the side of the narrow lower part for connecting the flap 5, and the drainage channel is used for drainage.
[0036] The flap 5 is connected to the positioning hole 302 through a symmetrical boss 501; a cavity 503 for accommodating the metal block 4 is set inside the flap 5; a protrusion 502 is provided at the upper edge of the cavity 503 for limiting the position during flipping to prevent excessive water impact force and the flap from rotating to the gravity balance point and being unable to reset.
[0037] The metal block 4 is installed in the cavity 503 of the flap 5 to increase gravity so that the flap 5 is in a closed state after installation; the filter screen 6 is a deep and long hollow column with dense through holes evenly distributed on the arc surface; the filter screen 6 is connected to the lower edge of the base 2 through a number of welding points 601.
[0038] The base 2 and the filter screen 6 are both made of stainless steel, the drain valve body 3 and the flap 5 are both made of ABS plastic, and the metal block 4 is made of magnet material. Stainless steel has the advantages of smooth surface, not easy to rust, and high hardness; ABS plastic has the advantages of high strength, high toughness, and good impact resistance.
[0039] Specifically, the floor drain core body 1 is composed of a holder 2, a drain valve body 3, a metal block 4, a flap 5, a filter screen 6 and other structures; the holder 2 is a stepped ring shape, with a stepped through hole in the middle for accommodating the drain valve body, and the annular surface at the other steps is a sealing ring contact surface. The top side of the drain valve body 3 is provided with an annular groove for compressing and fixing the drain valve body 3 and sealing to prevent overflow, and the lower constriction is used to connect the filter screen 6. A drainage channel is provided in the middle of the drain valve body 3, and the drainage channel is wide at the top and narrow at the bottom, and symmetrical side portions are provided at the lower narrow portion. The shaped positioning hole is used to connect the flap 5. A cavity 503 for accommodating the metal block 4 is arranged inside the flap 5. A protrusion 502 is arranged at the upper edge of the cavity 503 for limiting the position when flipping to prevent excessive water impact force and the flap from being unable to reset when it rotates to the gravity balance point. The metal block 4 is installed in the cavity 503 of the flap 5 to increase gravity so that the flap 5 is in a closed state after installation. The filter screen 6 is a deep and long hollow columnar body with dense through holes evenly distributed on the arc surface; the filter screen 6 is connected to the lower edge of the holder 2 through a number of welding points 601.
[0040] Working principle: When in use, the user first places the metal block 4 in the cavity 503 of the flap 5, then connects the bosses 501 on both sides of the flap 5 to the drain valve body 3, and finally installs the sealing ring 301 in the groove above the drain valve body 3 to complete the installation of the deodorizing device. The base 2 is welded to the filter screen 6 through the welding point 601, and then the deodorizing device is installed inside the drain valve body 3.
[0041] like Figure 7 Under the action of water pressure, when the water pressure impact water is greater than the gravity of the metal block 4 of the flap 5, the drainage channel of the drainage valve body 3 opens to drain water; when draining water, dirt and hair are directly discharged to the bottom of the filter 6, and the bottom of the filter 6 carries dirt and hair, and there are enough through holes on the top to ensure that the drainage is not blocked.
[0042] like Figure 8 When the water pressure impact force is large, after the flap 5 is opened, it is easy to flip over due to inertia, causing it to be unable to reset. Therefore, the protrusion 502 of the flap 5 plays a limiting role. After drainage, the valve core quickly resets under the gravity of the metal block 4, closing the drainage channel to prevent odor.
[0043] like Fig. 9 After the drain valve body 3 is closed, the sealing ring 301 plays a sealing role to prevent the gas in the pipeline from flowing back.
[0044] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
