[0054] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0055] Example 1

[0056] like Figures 1 to 8 As shown, this embodiment provides a filter element 1, including a support portion 11 and a plurality of guide ribs 12. The support portion 11 is provided with a filter cavity, and a first filter hole 101 is provided within the filter cavity. The plurality of guide ribs 12 are respectively connected to the support portion 11 and are arranged sequentially around the outer periphery of the filter cavity. Along the circumference of the filter cavity, a guide channel is formed between two adjacent guide ribs 12. The guide channel can guide the water flow entering the filter cavity to form a vortex. The wall surface of the guide rib 12 on the side facing away from the filter cavity is an outer guide surface 121. Along the direction facing away from the support portion 11, the outer guide surface 121 gradually tilts towards the central axis of the filter cavity.

[0057] In this invention, the drainage water flows into the filter chamber under the guidance of the flow channel, forming a vortex. Foreign objects in the drainage water flow can avoid clogging the first filter hole 101 of the filter chamber under the action of the vortex. On this basis, the outer flow surface 121 of the flow guide rib 12 on the side away from the filter chamber gradually tilts towards the central axis of the filter chamber along the direction away from the bearing part 11, that is, the outer wall surface of the flow guide rib 12 tilts inward. Thus, during the flow guidance of the drainage water flow, it is not easy to hook foreign objects, so that the flow channel is unobstructed and the filter element 1 can continue to operate. The filter chamber with the first filter hole 101 intercepts and retains foreign objects such as hair, so that foreign objects such as hair can accumulate in the filter chamber. On this basis, the flow channel guides the water flow into the filter chamber to form a vortex. Through the action of the vortex, foreign objects such as hair can be gathered together, realizing the effect of foreign object aggregation.

[0058] Specifically, the filter chamber is provided with a filter groove 111, and a first filter hole 101 is disposed in the filter groove 111. The groove opening of the filter groove 111 is provided with a flow guiding slope 112, and a flow guiding rib 12 is at least partially disposed on the flow guiding slope 112. Along the direction towards the filter groove 111, the flow guiding slope 112 gradually approaches the central axis of the filter chamber. The flow guiding slope 112 and the flow guiding rib 12 cooperate to enhance the flow guiding effect, so that the drainage water can flow into the filter groove 111 more efficiently.

[0059] More specifically, the diameter of the filter tank 111 is not less than 40mm and the depth is not less than 10mm. The above configuration ensures the storage capacity for foreign objects and ensures that when the drainage water flows into the filter tank 111, a vortex is generated, which drives the rotation of the foreign objects.

[0060] More specifically, the outer edge of the guide slope 112 is provided with a lap flange 113, and the bearing part 11 can be placed at the water inlet of the water leakage passage 22 through the lap flange 113. The above arrangement facilitates the placement of the bearing part 11.

[0061] More specifically, the outer periphery of the lap flange 113 is provided with a limiting protrusion 114, and the limiting protrusion 114 can be clamped in the alignment groove 214 at the water inlet of the water leakage passage 22. The above arrangement enables the filter element 1 to be stably placed at the water inlet of the water leakage passage 22, avoiding displacement of the filter element 1 under the scouring action of the water flow.

[0062] In the present embodiment, the groove wall and the groove bottom of the filter groove 111 are arc-shaped, the first filter hole 101 is provided with a plurality of filter holes, which are arranged at the groove bottom of the filter groove 111, the lap flange 113 is annular, and the limiting protrusion 114 is provided with four limiting protrusions, which are uniformly arranged on the outer peripheral surface of the lap flange 113.

[0063] Specifically, along the circumference of the filter cavity, the end face of one end of the guide rib 12 is a starting end face 122, and the end face of the other end is a terminal end face 123, which gradually approaches in the direction away from the bearing part 11. The above arrangement makes the protrusion of the guide rib 12 relative to the bearing part 11 more gradual, further avoiding the hooking of foreign matter.

[0064] More specifically, the angle between the starting end face 122 and the central axis of the filter cavity is smaller than the angle between the terminal end face 123 and the central axis of the filter cavity. The above arrangement makes the starting end face 122 steeper, thereby being able to better guide the drainage water flow, and makes the terminal end face 123 more gradual, thereby enabling the drainage water flow to enter the filter cavity more smoothly.

[0065] In the present embodiment, by providing the starting end face 122 and the terminal end face 123, the height of the guide rib 12 first gradually increases and then gradually decreases.

[0066] Specifically, the side of the guide rib 12 facing the filter cavity is provided with an inner guide surface 124, and an inner guide surface 124 and an adjacent outer guide surface 121 form a guide channel. The above arrangement ensures the guide effect of the guide channel.

[0067] More specifically, in the direction away from the bearing part 11, the inner guide surface 124 gradually approaches the central axis of the filter cavity. The above arrangement enables the drainage water flow to enter the filter cavity more efficiently.

[0068] Specifically, the guide channel is provided with no less than three, i.e. the guide rib 12 is provided with no less than three. The above arrangement ensures that the external water flow can smoothly enter the filter cavity through the guide channel.

[0069] More specifically, the height of each guide fin 12 is not higher than 10 mm, avoiding the hooking of foreign matters such as hair on the guide fin 12, while the design of the guide fin 12 should be as gentle as possible to weaken the impact of water flow, and the raised guide fin 12 can serve as a handle to facilitate the user to lift and pull.

[0070] In the present embodiment, four guide fins 12 are arranged on the bearing part 11, and four guide channels are formed between the four guide fins 12, which are arranged uniformly around the circumference of the filter cavity.

[0071] Specifically, the central angle A of the inlet pair of the guide channel to the central axis of the filter cavity is not less than 90°. The above arrangement ensures that foreign matters such as hair will not adhere to the guide fin 12 and the guide channel, improves the water guiding efficiency of the guide channel, and avoids the blockage of the guide channel.

[0072] More specifically, the bearing part 11 is provided with a second filter hole 102, which is arranged in the guide channel. The above arrangement improves the filtering efficiency of the bearing part 11.

[0073] In the present embodiment, the central angle A of the inlet pair of the guide channel to the central axis of the filter cavity is equal to 90°, and a plurality of second filter holes 102 are arranged in the guide channel. In the guide channel, the aperture of the second filter hole 102 gradually decreases in the direction away from the outer guide surface 121. In the direction of the water inlet flow, the second filter hole 102 is first small and then large, which can guide the water inlet flow to the large hole and more easily form a vortex.

[0074] Specifically, the outer guide surface 121 is provided with a third filter hole 103, which penetrates the guide fin 12 and the bearing part 11. The above arrangement allows emergency water to flow through the third filter hole 103 in the case of blockage of the first filter hole 101.

[0075] More specifically, a plurality of third filter holes 103 are arranged on the outer guide surface 121, and the first filter hole 101, the second filter hole 102 and the third filter hole 103 all penetrate to the side of the bearing part 11 away from the guide fin 12.

[0076] Specifically, a guide groove 13 is arranged at the junction of the guide slope 112 and the outer guide surface 121 in the guide channel, and the water inlet flow enters the filter cavity through the guide groove 13 under the guidance of the guide slope 112.

[0077] In the embodiment, the plurality of guide ribs 12 are protruded on one side of the bearing part 11, the guide rib 12 is in a long strip shape, the plurality of guide ribs 12 are uniformly arranged along the circumference of the filtering cavity, one end of the guide rib 12 is a starting end, and the other end is a terminal end, the distances from the plurality of starting ends to the central axis of the filtering cavity are equal, from the starting end to the terminal end, the outer guide surface 121 and the inner guide surface 124 gradually approach the central axis of the filtering cavity, the guide rib 12 further comprises a limiting surface connected to the inner guide surface 124 on the side of the filtering cavity, the outer guide surface 121 is arranged on the side of the guide rib 12 away from the filtering cavity, the inner guide surface 124 and the limiting surface are arranged on the side of the guide rib 12 towards the filtering cavity, the starting end surface 122 is arranged at the junction of the outer guide surface 121 and the inner guide surface 124, and the terminal end surface 123 is arranged at the junction of the outer guide surface 121 and the limiting surface. In the guide channel, the round corner of the guide groove 13 is large enough to avoid hooking foreign matters such as hair, so that the plurality of guide channels are uniformly arranged along the circumference of the filtering cavity, one end of the guide channel is a guide inlet, and the other end is a guide outlet, the guide inlet is communicated to the outside of the filtering cavity, the guide outlet is communicated to the filtering cavity, and from the guide inlet to the guide outlet, the guide channel gradually approaches the central axis of the filtering cavity, and the cross-sectional area gradually decreases.

[0078] The embodiment also provides a floor drain, which comprises a shell 2 and the above-mentioned filtering piece 1, and the filtering piece 1 is arranged in the shell 2.

[0079] In the floor drain, the drainage flow forms a vortex after entering the filtering cavity under the guidance of the guide channel, and the foreign matters in the drainage flow can avoid blocking the first filter hole 101 of the filtering cavity under the action of the vortex. On this basis, the outer guide surface 121 of the guide rib 12 away from the filtering cavity gradually approaches the central axis of the filtering cavity along the direction away from the bearing part 11, that is, the outer wall surface of the guide rib 12 is inclined towards the inside, so that the foreign matters are not easy to be hooked in the process of guiding the drainage flow, the guide channel is smoothly guided, the continuous operation of the floor drain is ensured, the foreign matters such as hair are intercepted and retained by the filtering cavity provided with the first filter hole 101, so that the foreign matters such as hair can be accumulated in the filtering cavity. On this basis, the water flow entering the filtering cavity forms a vortex through the guide channel, and the foreign matters such as hair can be gathered together through the action of the vortex, thereby realizing the gathering effect of the foreign matters.

[0080] Specifically, the floor drain further comprises a cover body 3, the shell 2 is provided with a containing groove 21, the groove bottom of the containing groove 21 is communicated with a water leakage channel 22, the filtering piece 1 is arranged on the groove bottom of the containing groove 21 to cover the water inlet of the water leakage channel 22, and the cover body 3 is arranged at the groove opening of the containing groove 21. The above-mentioned arrangement avoids that the drainage flow directly flows into the filtering cavity, and ensures the guiding effect of the guide rib 12.

[0081] In the embodiment, the cover 3 shields the filter cavity in the axial direction of the filter cavity, and the cover 3 and the inner wall of the accommodating groove 21 are spaced apart to ensure that the water flow can flow into the accommodating cavity, and the overlapping flange 113 of the filter piece 1 abuts against the groove bottom of the accommodating groove 21, and the filter groove 111 extends into the water leakage passage 22.

[0082] Specifically, the side wall of the accommodating groove 21 is connected to the groove bottom surface through a guide surface 211, and the included angle B between the guide surface 211 and the central axis of the water leakage passage 22 is in the range of 30°-60°. The above-mentioned arrangement enables the water flow flowing into the accommodating groove 21 to be guided by the guide surface 211 to the filter piece 1, thereby improving the drainage efficiency.

[0083] More specifically, the guide surface 211 is provided with a flow resistance rib 212 configured to reduce the flow rate of the water flow. Since the water flow enters the filter cavity at too high a speed, the filter piece 1 is prone to lose the effect of rotational flow guide. By increasing the flow resistance rib 212, the flow rate of the water flow can be slowed down, so that the hair inside the filter cavity can be made to produce a rotational effect with the water flow regardless of where the water enters.

[0084] In the embodiment, the size of the guide surface 211 on the central axis of the water leakage passage 22 is not less than 5 mm, thereby ensuring the flow guide range.

[0085] Specifically, a plurality of support tables 23 are arranged in the accommodating groove 21, and the cover 3 is arranged on the plurality of support tables 23. The above-mentioned arrangement enables the cover 3 to be conveniently and quickly placed in the accommodating groove 21.

[0086] More specifically, as shown by the arrow in the figure, Figure 8 In the radial direction of the filter cavity, each support table 23 is provided with a flow guide rib 12 opposite to it. The above-mentioned arrangement ensures the rotational effect of the water flow.

[0087] More specifically, the support table 23 is lower than the groove opening of the accommodating groove 21, and a limiting groove 231 is arranged on the support table 23, the cover 3 is limited in the limiting groove 231, and the cover 3 and the side wall of the limiting groove 231 are spaced apart. The above-mentioned arrangement ensures that the water flow flows into the position of the support table 23, thereby better forming a vortex.

[0088] Specifically, the groove bottom of the accommodating groove 21 is provided with a support groove 213, the groove bottom of the support groove 213 is provided with a communication port communicated with the water leakage passage 22, the overlapping flange 113 of the filter piece 1 abuts against the groove bottom of the support groove 213, and the top surface is flush with the groove opening of the accommodating groove 21. The above-mentioned arrangement enables the water flow to flow more smoothly into the filter cavity.

[0089] More specifically, the bottom of the accommodating groove 21 is further provided with a positioning groove 214 communicated with the supporting groove 213, when the lapping flange 113 abuts against the groove bottom of the supporting groove 213, the limiting protrusion 114 is limited and clamped in the positioning groove 214. The above setting avoids displacement of the filter element 1 relative to the shell 2.

[0090] In the embodiment, the cover 3 is rectangular, four support tables 23 are arranged in the accommodating groove 21, four corners of the cover 3 are respectively arranged in the limiting grooves 231 of the four support tables 23, the guide surface 211 is provided with four flow resistance ribs 212, the bottom of the accommodating groove 21 is provided with four positioning grooves 214, the bearing part 11 is provided with four flow guide ribs 12, in the radial direction of the filter cavity, each limiting groove 231 is opposite to one flow resistance rib 212, one positioning groove 214 and one flow guide rib 12, and the limiting groove 231 is opposite to the junction of the starting end surface 122 and the terminal end surface 123.

[0091] Specifically, the drain core 4 for deodorization is installed at the water outlet of the water leakage passage 22 of the shell 2, and the filter element 1 and the drain core 4 are arranged at intervals, so that the drainage is smooth.

[0092] In the embodiment, the drain core 4 is a component in the prior art, and the specific structure and working principle thereof will not be described here.
