[0034] In order to keep the following description of the embodiments of the present utility model clear and concise, the detailed descriptions of known functions and known components are omitted in the present utility model.

[0035] As Figures 1 to 3 shown, an embodiment of the present utility model discloses a bathroom floor drain device, which is used to be installed at the floor drain hole on the bathroom floor. The bathroom floor drain device includes: a floor drain main body 10, an outer ring sleeve 30, an inner ring sleeve 40, a floor drain cover body 20, and a floor drain inner core 70.

[0036] The upper port of the floor drain main body 10 is larger than the lower port. The upper port of the floor drain main body 10 extends from the bottom of the bathroom floor into the hole section where the base layer 100 of the bathroom floor is located and is fixedly installed. The outer ring sleeve 30 is inserted into the inner hole of the upper port of the floor drain main body 10 from above the floor drain main body 10. A first sealing member 50 is provided between the outer ring sleeve 30 and the inner ring sleeve 40; the inner ring sleeve 40 is inserted into the inner hole of the outer ring sleeve 30 from above the outer ring sleeve 30 and allows the inner ring sleeve 40 to move axially relative to the outer ring sleeve 30. Moreover, a supporting ring 41 is formed on the radially outer side of the upper end of the inner ring sleeve 40, and the floor drain cover body 20 is buckled on the supporting ring 41. A second sealing member 60 is provided between the supporting ring 41 and the upper end of the outer ring sleeve 30.

[0037] In the present utility model, serrated notches 80 are machined on the inner hole wall of the outer ring sleeve 30 and the outer peripheral surface of the inner ring sleeve 40. Thus, after the inner ring sleeve 40 adjusts its axial position relative to the outer ring sleeve 30, the inner ring sleeve 40 remains at the adjusted position. Since the floor drain cover body 20 is buckled on the supporting ring 41 of the inner ring sleeve 40, the height of the floor drain cover body 20 can be adjusted by adjusting the axial position of the inner ring sleeve 40, so as to adapt to the surface layer 200 of the bathroom floor.

[0038] The first sealing member 50 is a sealing ring. Two sealing rings are sleeved on the outer peripheral surface of the outer ring sleeve 30. The outer ring sleeve 30 and the inner hole wall of the upper port of the floor drain main body 10 are sealed by two sealing rings; moreover, the inner hole wall of the upper port of the floor drain main body 10 is configured as a tapered hole surface. Thus, after the outer ring sleeve 30 is inserted into the floor drain main body 10, a pre-tightening is formed between the outer ring sleeve 30 and the floor drain main body 10, and the relative position between the outer ring sleeve 30 and the floor drain main body 10 is limited.

[0039] The second sealing member 60 is a gasket, and the gasket is configured as follows: the inside of the gasket has an annular hollow portion 61, and bending portions are formed on both sides in the radial direction of the annular hollow portion 61. The bending portions enable the second sealing member 60 to generate a large elastic deformation in the axial direction. Thus, when adjusting the axial position of the inner ring sleeve 40, the second sealing member 60 adapts to the position change between the inner ring sleeve 40 and the outer ring sleeve 30 through axial deformation, so that the inner ring sleeve 40 and the outer ring sleeve 30 always obtain a sealing effect.

[0040] The present utility model provides two second sealing members 60 with specific structures. The first one is: As Figure 2As shown, the bent portion is an inwardly concave bent portion 62 that deforms toward the annular hollow portion 61. In this way, when the second sealing member 60 is pressed, the inwardly concave bent portion 62 realizes axial retraction by deforming toward the annular hollow portion 61; The second type is: as Figure 3 shown, the bent portion is an outwardly convex bent portion 63 that deforms toward the outside of the annular hollow portion 61. In this way, when the second sealing member 60 is pressed, the outwardly convex bent portion 63 realizes axial retraction by deforming toward the outside of the annular hollow portion 61.

[0041] An installation hole is provided in the middle of the floor drain cover body 20. The floor drain inner core 70 is installed in the installation hole, and the lower part of the floor drain inner core 70 extends into the floor drain main body 10; The floor drain inner core 70 has an upper filter cover 71 and a lower filter cover 72 arranged at an axial interval. The water on the bathroom floor is discharged through the floor drain main body 10 after being filtered by the upper filter cover 71 and the lower filter cover 72 in two layers. Preferably, an anti-odor bottom cover 73 is pivotally connected to the bottom of the floor drain inner core 70. In this way, when drainage is required, the water forces the anti-odor bottom cover 73 to open by pivoting, and when drainage is not required, the anti-odor bottom cover 73 closes by automatically pivoting in the reverse direction, thereby preventing odor return.

[0042] The bathroom floor drain device provided by the present utility model has at least the following advantages:

[0043] The bathroom floor drain device provided by the present utility model can adapt to bathroom floors with a larger range of size variations.
