Technical Field
[0001] The utility model relates to the field of bathrooms, in particular to a floor drain. Background Art
[0002] A floor drain is a drainage device that connects the ground to the drainage pipe system. The floor drain shell of the old-fashioned floor drain is only provided with a drainage port, and odor prevention is achieved by setting an odor-proof bend at the lower end of the outer filter on the floor drain shell; however, the old-fashioned floor drain shell is installed on the ground, and replacing it with a set of new floor drains requires the removal of the old-fashioned floor drain shell, which is a difficult project. For this reason, the inventor of the application has developed a floor drain product suitable for replacing and renovating old floor drains (202311218180.6), and the publication date is December 01, 2023.
[0003] The diameter of the inner core of the above-mentioned floor drain is relatively small, and only a sealing rubber ring is provided at the lower part, so the types of suitable floor drain outer shells are limited, which affects the adaptability of the floor drain product.
[0004] In view of this, the inventor conducted in-depth research on the above-mentioned defects in the prior art, and thus came up with this case. Utility Model Content
[0005] The main purpose of the utility model is to provide a floor drain which has the characteristic of good adaptability.
[0006] In order to achieve the above purpose, the solution of the utility model is:

[0008] Furthermore, an annular notch is formed on the upper portion of the edge of the opening disk, and the sealing rubber pad is embedded in the annular notch.
[0009] Furthermore, the sealing rubber pad at the edge of the opening disk forms an annular film layer, and the thickness of the annular film layer gradually decreases from the inside to the outside.
[0010] Furthermore, the sealing rubber pad is separately provided from the drainage cylinder, and the sealing rubber pad is detachably mounted on the drainage cylinder.
[0011] Furthermore, the upper opening of the open plate is formed with a sinking groove, and the edge of the filter screen is stuck in the sinking groove.
[0012] Furthermore, a protrusion convex upward is formed in the middle of the filter screen.
[0013] Furthermore, a handle portion is formed on the raised portion.
[0014] Furthermore, the handle portion includes a lifting button and a fixing portion, a mounting hole is formed on the filter screen, the lifting button is located at the upper portion of the mounting hole, the fixing portion is located at the lower portion of the mounting hole, and the lifting button and the fixing portion pass through the mounting hole and are locked and connected.
[0015] Furthermore, the handle is a lifting rod rotatably connected to the filter screen.
[0016] Furthermore, a deodorizing component is connected to the lower opening of the central tube.
[0017] After adopting the above structure, the floor drain of the utility model has at least the following features:
[0018] Beneficial effects:
[0019] 1. By placing the sealing rubber pad on the outer wall of the drain cylinder and extending it upward to the edge of the opening plate and the outer side of the center cylinder with a rubber ring, it can be sealed through the rubber ring on the outer side of the center cylinder, as well as through the sealing rubber pad on the edge of the opening plate and the lower surface of the opening plate. This improves the adaptability of the floor drain installed on the floor drain shell and ensures the sealing effect.
[0020] Second, the thickness of the annular film layer gradually decreases from the inside to the outside, so that the annular film layer can be easily deformed to better fit the inner wall surface of the floor drain shell.
[0021] 3. The sealing rubber pad and the drainage cylinder are manufactured separately and are mounted on the drainage cylinder for fixing. The annular notch is clamped with the upper end of the sealing rubber pad so that the upper end of the sealing rubber pad can be firmly fixed to the edge of the opening plate.
[0022] Fourth, the handle portion can be a handle button or a handle rod, and the upward protrusion allows the debris in the flowing water to be preferentially accumulated on the periphery of the protrusion, thereby preventing the debris from completely blocking the filter hole.
[0023] 5. The anti-odor component can be a magnetic anti-odor flap to prevent the odor from rising.
[0024] Compared with the prior art, the utility model provides a sealing rubber pad so that the drainage cylinder can be better adaptably installed with the floor drain shell, thereby ensuring the sealing effect and preventing the water from bypassing the filter screen from the periphery and draining downwards.
