Device mounted on upper part of floor drain

[0016]The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0017]Such asfigure 1 Shown is a schematic structural diagram of an embodiment of a device installed above a floor drain of the present invention. Visible in the picture:

[0018]The left side of the figure is the pipe 1 of the vertical drainage system; the floor drain 3 is set on the right side of the pipe 1; the right side of the pipe 1 has a gap at the position corresponding to the opening on the side of the floor drain 3; the floor drain 3 shown is A typical trap form, the existence of trap 7 enables the liquid surface 6 to effectively block the smell of the pipe 1; a device body 2 is provided above the upper opening of the floor drain 3; the device body 2 is made of adhesive 4 is fastened on the ground 5; the right side of the device body 2 shown in the figure is provided with a water inlet pipe 2-4; the side of the shown water inlet pipe 2-4 close to the device body 2 (that is, the left side of the figure) is relatively far away The other side of the device body 2 (the right side of the figure) is at a lower level and consists of three concentric circular tubes with different outer diameters. The largest outer diameter tube is closest to the device body 2, and then the outer diameter Decrease from the outside, the outer diameter of the outermost round tube is the smallest; these different outer diameters match the inner diameters of the drain pipes of different specifications of the washing unit; the upper cover 2-1 is provided above the device body 2 shown in the figure; the upper cover An operating hole 2-3 is provided on the right side of 2-1; the operating hole 2-3 shown in the figure is currently closed by a plug 2-2.

[0019]For clarity, the washing unit and connecting pipe are not shown in the figure. It can be seen from the foregoing that one end of the connecting pipe is connected to the drain pipe of the washing unit, and the other end is connected to the water inlet pipe 2-4 of the device body 2. The drain of the washing unit flows from the drain pipe through the connecting pipe into the device body 2, and then drains to the floor drain 3. The opening in the upper part finally flows through the floor drain 3 and enters the pipe 1 of the drainage system.

[0020]From the foregoing, it can be seen that the operating hole 2-3 provided on the upper cover 2-1 can be opened or closed (this embodiment can be achieved by unscrewing and removing the plug 2-2 or installing and tightening the plug 2-2); When the operation hole 2-3 is opened, the user can observe the internal condition of the device body 2, and can put chemicals to clean the dirt and melt the blockage into the device body 2; when the operation hole 2-3 is closed, the device body 2 is in a sealed state .

[0021]Such asfigure 2Shown is a schematic structural diagram of another embodiment of a device installed above the floor drain of the present invention. It can be seen in the figure: this embodiment isfigure 1 The difference in the illustrated embodiment lies in the way in which the device body 2 and the floor drain 3 are connected.figure 1 The device body 2 of the illustrated embodiment is fastened to the ground 5 by an adhesive 4, and is not substantially connected to the floor drain 2;figure 2The outer surface of the upper opening of the floor drain 3 of the illustrated embodiment is machined with external threads, and a flange is machined below the device body 2. The maximum diameter of the flange is smaller than the bottom diameter of the outer thread of the outer surface of the upper opening of the floor drain 3 and larger than The size of the inner cavity of the floor drain 3 corresponding to the device body 3; the middle part 8 is located below the device body 2 and is blocked by the flange of the device body 2 and cannot be separated; the connection position of the middle part 8 and the upper opening of the floor drain 3 The inner surface is machined with an inner thread that matches the outer thread of the outer surface of the upper opening of the floor drain 3; the inner thread of the middle part 8 is screwed into the outer thread of the floor drain 3, and the lower surface of the flange of the device body 2 is close to the floor drain 3 The upper surface of the upper opening can be effectively connected; it can be seen in the figure that a rubber pad 9 is provided between the lower surface of the flange of the device body 2 and the upper surface of the floor drain 3 to enhance the sealing effect.

[0022]figure 2The remaining structure of the embodiment is the same asfigure 1 The embodiments shown are the same, and will not be repeated here.

[0023]It is clear,figure 1 as well asfigure 2The described embodiment can fully adapt to different types of floor drains.

[0024]The above-mentioned embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited by the above-mentioned embodiments, and any other changes, modifications, substitutions, combinations, etc. made without departing from the spirit and principle of the present invention Simplified, all should be equivalent replacement methods, and they are all included in the protection scope of the present invention.
