DETAILED DESCRIPTION

[0020] The following describes the specific implementation of the utility model in detail in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand how to practice the utility model. Although the utility model is described in conjunction with its preferred specific embodiments, these embodiments are only illustrative, rather than limiting the scope of the utility model.

[0021] Specific embodiment 1: Please refer to Figure 1-4 The invention discloses an anti-clogging floor drain, comprising: a decorative cover 1, a cover plate 2, a basket filter 3, a fixed protrusion 4, a built-in water seal and a panel 9, wherein the decorative cover 1, the cover plate 2, the basket filter 3, the fixed protrusion 4 and the built-in water seal are all movably arranged on the panel 9, wherein the decorative cover 1 is arranged on the cover plate 2 for decoration, and a plurality of filter holes 21 are also provided on the cover plate 2, the basket filter 3 and the fixed protrusion 4 are arranged on the lower side of the cover plate 2 and the upper side of the built-in water seal, and the upper side space of the panel 9 is connected with the lower side space through the built-in water seal; when in use, water can be filtered through the cover plate 2 and the basket filter 3 in turn and then discharged through the built-in water seal.

[0022] The fixed protrusion 4 is fixed on the basket filter 3 to facilitate the removal of the basket filter 3. In other preferred embodiments, the fixed protrusion 4 and the basket filter 3 can be an integrated structure; further, a plurality of mesh holes 31 are provided on the basket filter 3; in order to achieve graded filtration, the aperture of the mesh hole 31 is smaller than the aperture of the filter hole 21.

[0023] See also Figure 2 The built-in water seal is composed of an inner core 5, a connecting ring 6 and an outer core 7; the inner core 5 includes a tubular inner core body 51 and a limit ring 52 fixed to the upper end of the inner core body 51; the outer core 7 is a tubular structure with a closed lower end, and six water outlet holes 71 are opened on the upper part of the outer periphery of the outer core 7, and the six water outlet holes 71 are evenly distributed around the axis of the outer core 7; in addition, in order to stably place the basket filter 3, the outer diameter of the basket filter 3 should be larger than the inner diameter of the inner core 5;

[0024] Furthermore, in order to ensure the water outlet efficiency and the stability of the structure, the cross-sectional width of the water outlet hole 71 is not greater than one sixth of the cross-sectional circumference of the outer core 7 body;

[0025] The connecting ring 6 is fixedly sleeved on the outer periphery of the outer core 7, and the connecting ring 6 is located on the upper side of the six water outlet holes 71; in the present embodiment, the outer diameter of the limiting ring 52 is larger than the inner diameter of the outer core 7, and the inner core body 51 is placed on the inner side of the outer core 7 by crimping the limiting ring 52 with the port of the outer core 7, and at the same time, in order to achieve the purpose of water sealing, the lower port of the inner core body 51 is located on the lower side of the six water outlet holes 71; water flows into the outer core 7 through the inner core 5, and then flows out from the water outlet holes 71. Since the lower port of the inner core body 51 is located on the lower side of the six water outlet holes 71, water flows unidirectionally in the built-in water seal and water always stays inside the outer core 7 to isolate the air between the water outlet holes 71 and the inner core 5, thereby achieving the purpose of water sealing; in addition, in order to ensure the water sealing effect, the length of the outer core 7 on the lower side of the connecting ring 6 is not less than 50 mm.

[0026] A conical groove 93 is provided in the middle of the panel 9, and a clamping hole 91 is provided longitudinally through the axis of the conical groove 93. The outer core 7 is arranged to pass through the clamping hole 91, wherein the water outlet holes 71 are all located on the lower side of the panel 9; the inner diameter of the clamping hole 91 is smaller than the outer diameter of the connecting ring 6, and the outer core 7 is movably placed on the panel 9 through the connecting ring 6, at which time the connecting ring 6 is crimped with the groove wall of the conical groove 93.

[0027] The anti-clogging floor drain also includes a filter ring 8; see Figure 3 and Figure 4 , an annular debris groove 92 is provided on the panel 9 and outside the conical groove 93, and the filter ring 8 is laid on the annular debris groove 92; in order to achieve the purpose of graded filtration, the cover plate 2 is covered on the conical groove 93, and the upper end surface of the cover plate 2 should not be higher than the upper end surface of the panel 9; when in use, the local drain needs to be installed in the place where drainage is required in the house. After draining, the debris or particles in the water will be filtered when passing through the filter ring 8, and the smaller and heavier ones will sink into the annular debris groove 92 for accumulation, and the larger ones will be blocked. Outside the floor drain, the water is then filtered through the filter holes 21 of the cover plate 2, which will further block larger debris in the water outside the floor drain, while releasing smaller debris or particles. Then, when the water flows to the basket filter 3, the basket filter 3 will intercept smaller debris and remove most of the larger debris in the water. The water after three-stage filtration finally flows into the built-in water seal and is discharged through the water outlet 91. When the floor drain needs to be cleaned, only the cover plate 2, the basket filter 3, and the built-in water seal need to be taken out in turn and cleaned one by one. The whole process is convenient, fast, time-saving and labor-saving.

[0028] Through the technical solution, the various parts of the floor drain are movably assembled, so that when cleaning and maintaining the floor drain, the disassembly of the floor drain is more convenient and quick, and there is no dead corner for cleaning, which saves time and effort.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
