Self-sealing deep water seal floor drain

technical field

The invention belongs to the technical field of construction and relates to a deep water seal floor drain, in particular to an automatic sealing type deep water seal floor drain.

Background technique

As people's requirements for quality of life are getting higher and higher, the demand for home decoration materials is also increasing day by day. Daily necessities are not only satisfied with their simple functions, such as floor drains installed on the surface of kitchens, bathrooms and balconies. , it not only meets the connection with the sewer pipe, but also has higher and higher requirements for its functions of deodorization, prevention of harmful gases, mosquitoes and germs. Although the floor drain is small, it involves thousands of households and is related to people's health and environmental sanitation.

At present, the water-sealed floor drains commonly used in floor buildings can store a small amount of water to form a water-sealed and deodorant layer. Because the water-sealed depth is small, the water is easier to evaporate and dry, and the odor is easy to escape into the room, and the deodorant and insect-proof effect is not ideal. Moreover, the connection between the ground waterproof membrane and the floor drain cannot be treated in any way, which may easily cause leakage of the ceiling of the lower room. This is a problem that is concerned by thousands of households, but it is not easy to solve.

For the problem that above-mentioned floor drain exists, people have proposed various solutions through long-term exploration, and some have also applied for a patent. For example, a Chinese patent discloses a deep water seal floor drain [authorized announcement number: CN200988988Y], which includes an upper tray and a leaky cover plate covering it. Stepped shaft shape, the filter cup is movable inside the step, the upper end of the overflow cup with a closed bottom is fixedly connected to the outer wall of the step of the water tank, the lower part of the water tank is suspended in the overflow cup, and the ground of the water tank is up to The height of the water seal between the overflow holes on the side wall of the overflow cup is more than 6 cm. The water is not easy to volatilize, and the anti-odor and anti-insect effect is improved.

But this kind of deep water seal floor drain can't completely prevent the overflow of bad smell, and it mainly has the following disadvantages: 1. The water storage time in the water seal is too long to easily breed bacteria, and the bad smell produced by bacteria can easily enter the room; 2. Water seal If the water stored in the toilet is too long, it will be evaporated slowly, and the odor will easily enter the room. Such a deep water seal floor drain has poor anti-odor effect, easily causes environmental pollution, and brings unnecessary troubles to life.

Contents of the invention

The purpose of the present invention is to solve the above-mentioned problems in the prior art, and propose a self-sealing deep-water-sealed floor drain that can effectively prevent odors from entering the room and has double seals.

The purpose of the present invention can be achieved through the following technical solutions:

A self-sealing deep water seal floor drain, comprising a bottom-sealed cylinder, a water outlet is opened on the side wall of the cylinder, a panel is fixedly connected to the upper part of the cylinder, and a straight drain is arranged at the lower part of the cylinder. tube, the straight pipe communicates with the cylinder, and it is characterized in that a sealing plate is provided above the straight pipe in the cylinder, and the cylinder is provided with a sealing plate that can make the sealing plate along the cylinder There is a guide mechanism for the body to move up and down, and a reset mechanism that uses magnetism to form a seal between the sealing plate and the cylinder.

When the self-sealing deep water seal floor drain is used for the first time, due to the sealing of the bottom of the cylinder, a section of water seal extending to the water outlet will be formed at the bottom of the cylinder, which can prevent cockroaches and odors from entering the room. When the water flows through the sewer, the gravity of the water pushes the sealing plate so that the sealing plate moves along the cylinder under the guidance of the guiding mechanism. After the movement, the seal cannot be formed between the sealing plate and the cylinder. Inside the discharge pipe; due to the effect of water pressure, the water seal flows from the water outlet to the outside of the cylinder to achieve the effect of drainage, while the water flow behind gradually forms a new water seal. When the water flow gradually decreases until there is no water flow in the sewer, the magnetic reset mechanism makes the sealing plate move along the cylinder under the guidance of the guide mechanism until a seal is formed between the sealing plate and the cylinder. In this way, the water seal and the sealing plate can deodorize and prevent insects at the same time. Even after the water seal in the cylinder evaporates, the seal formed between the sealing plate and the cylinder can also prevent odor and cockroaches from entering the room.

In the above-mentioned self-sealing deep water seal floor drain, the guide mechanism includes a bracket fixed in the cylinder and a guide rod that penetrates the bracket and can move up and down along the cylinder, and one end of the guide rod is connected with the sealing plate .

In the above-mentioned self-sealing deep water seal floor drain, the bracket is located below the sealing plate, and a guide pad is provided at the bottom of the bracket, and the above-mentioned guide rod is penetrated in the guide pad and can move up and down along the guide pad.

Because the thickness of the support is not large, if the guide rod moves up and down along the support independently, the guide rod will shake during the moving process, resulting in an imprecise seal between the sealing plate and the cylinder body. The sealing gasket can effectively prevent the shaking of the guide rod during the moving process, and can also provide convenience for the installation of the magnetic reset mechanism.

In the above-mentioned self-sealing deep water seal floor drain, the reset mechanism includes a permanent magnet arranged in the guide pad and a permanent magnet arranged at the lower end of the guide rod, and the two permanent magnets are arranged with opposite poles.

The purpose of such arrangement is to make use of the attraction force between the two permanent magnets to form a seal between the sealing plate and the cylinder body. The gravity of the water can ensure that when the water flows into the floor drain, the sealing plate can be pushed to facilitate the passage of the water.

In the above-mentioned self-sealing deep water seal floor drain, the cylinder body is provided with an annular shoulder, and the annular shoulder is arranged above the sealing plate. When the sealing plate and the annular shoulder abut, the sealing A seal is formed between the plate and the cylinder.

The setting of the annular shoulder can facilitate the abutment of the sealing plate, so that the sealing between the sealing plate and the cylinder body is stronger and the sealing performance is better. The sealing plate is arranged under the annular shoulder, and when there is water flow, the sealing plate will not be blocked by the annular shoulder, which facilitates the passing of the water flow.

In the above-mentioned self-sealing deep water-sealed floor drain, the cylinder body includes a sleeve and a water-seal groove connected to the sleeve below the sleeve, the water-seal groove is provided with the above-mentioned water outlet, and the The annular shoulder is arranged at the lower port of the sleeve.
