Description

A self-closing floor drain

technical field

The utility model relates to a floor drain facility for a fixed building, in particular to an automatically closed floor drain.

Background technique

A floor drain is a sanitation device that drains indoor ground water. The traditional water-sealed floor drain is the most widely used in the existing market. The traditional water-sealed floor drain has a bell-type structure, that is, a buckle bowl is used to buckle the mouth of the drain pipe to create a "U"-shaped trap to achieve airtightness. The purpose is to rely on the height of the deposited water level to seal the anti-gas. Submarine T-type automatic sealing four-proof floor drain is also widely used. It uses the gravity balance principle of permanent magnet to brake the opening and closing of the floor drain device up and down. It uses T-shaped pipe and ABS gasket structure. The spring self-sealing floor drain is sealed by spring force, has a simple structure and has many applications.

The above-mentioned prior art scheme, the water-sealed floor drain has a shallow water seal, and it is easy to dry up and fail if it is not used for a long time. Many household floor drains are short of water for a long time and dry up, cockroaches are easy to enter, and the dirty things inside are not easy to clean. Although spring self-sealing floor drains and seesaw self-sealing floor drains have the excellent characteristics of large and fast drainage; but because they are prone to failure and damage, they cannot achieve the expected effect, and their development prospects are not very good. Submarine T-type self-sealing four-proof floor drain has large and fast displacement, and has a certain sewage discharge effect and sealing effect; but because its sealing diameter is vertical and the sealing cover is horizontal, the sealing port cannot be opened too much. Otherwise, it is not easy to be sucked back by the magnetic force, which limits a certain flow of water, and the sealing cover is also easily damaged due to the impact of the impact; because the inner core pipe is arranged vertically, the structural design of the sealing interface is not good, resulting in poor sealing effect.

Utility model content

In view of the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide a floor drain with automatic sealing, smooth drainage, easy cleaning of dirt and easy maintenance and replacement.

In order to solve the above-mentioned problems in the prior art, the utility model is realized through the following technical scheme: an automatic sealing floor drain, the floor drain includes a J-shaped water pipe, and its improvement lies in that the lower end of the J-shaped water pipe and the ferroalloy baffle pass through Hinge connection, the opening of the lower end of the J-shaped water pipe is provided with a permanent magnet, and the lower end of the J-shaped water pipe is closed when the ferroalloy baffle is in full contact with the opening of the lower end of the J-shaped water pipe.

The ferroalloy baffle plate is provided with a layer of soft rubber skin on the end surface of the contact end with the J-shaped water pipe.

Compared with the prior art, the utility model has the beneficial effects that the floor drain has smooth drainage, easy cleaning of dirt, good sealing effect, convenient maintenance and replacement, simple structure, low cost, firmness and reliability, and the like.

Description of drawings

Fig. 1 is the outline drawing of the present utility model.

Fig. 2 is a top view of the panel of the present invention.

Among them: porous concave panel 1, J-shaped water pipe 2, iron alloy baffle 3, hinge 4, permanent magnet 5.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

During specific implementation, as shown in Figure 1 to Figure 3, a kind of automatic sealing floor drain, referring to Figure 1, the water outlet of this floor drain can be automatically opened and closed according to the size of the accumulated water pressure so that the accumulated water in the floor drain reaches a certain level. It is automatically discharged when it is high; when no accumulated water enters, the ferroalloy baffle plate 3 will seal the water outlet of the floor drain under the combined force of its own gravity and the attractive force of the permanent magnet 5. When a small amount of water flows into the J-shaped water pipe 2, the ferroalloy baffle 3 will not be opened immediately, only when the accumulated water reaches a certain height, when the water pressure is greater than the resultant force of the self gravity of the ferroalloy baffle 3 and the attractive force of the permanent magnet 5, Ferroalloy baffle plate 3 just can be washed away. At this time, due to the large amount of accumulated water, a scouring effect will be formed in the J-shaped water pipe 2, so that the dirt in the J-shaped water pipe 2 can be more easily discharged and washed away, so that the J-shaped water pipe 2 will not be blocked.

Referring to Fig. 2, the top of the J-shaped water pipe 2 is provided with a porous concave panel 1, and the porous concave panel 1 is stamped from stainless steel. The porous concave panel 1 is mainly used to block slightly larger sundries and as an aesthetic decoration, and the holes can be designed into different hole types such as linear holes, circular holes, and oval holes. The size of the porous concave panel 1 matches the outer diameter of the J-shaped water pipe 2 . The function of the concave shape is to ensure that there is no water on the ground.

Referring to Fig. 1 and Fig. 3, the ferroalloy baffle 3 and the lower end of the J-shaped water pipe 2 are rotatably connected by a hinge 4 to realize the swing when the ferroalloy baffle 3 is opened and closed. The thickness of the ferroalloy baffle 3 is moderate, such as in 2- 3mm, the shape can be square or circular, and the size is preferably to cover the lower opening of the J-shaped water pipe 2. For better sealing, the end face of the ferroalloy baffle 3 and the contact end of the J-shaped water pipe 2 can be fixed with a layer of soft rubber with adhesive or screws, and the size and shape of the rubber is corresponding to the ferroalloy baffle. The permanent magnet 5 can be ring-shaped, and the permanent magnet 5 is nested on the inner wall of the opening at the lower end of the J-shaped water pipe 2, and can be bonded with an adhesive, or snapped into a notch in the pipe wall by clamping. The permanent magnet 5 can also be in the shape of a tile, and a plurality of permanent magnets 5 in the shape of a tile can be evenly distributed on the inner wall of the J-shaped water pipe 2. In order to ensure the sealing effect, the permanent magnet 5 should not exceed the opening end face of the J-shaped water pipe 2. During actual production, it is better to make the permanent magnet 5 and the outlet port of the J-shaped water pipe 2 1-2mm apart.

The utility model can be closed and connected with the drainage pipeline, and can also be opened and connected, which can prevent small animals such as cockroaches and mice from entering the room through the J-shaped water pipe 2 of the floor drain. Air enters the room through the J-shaped water pipe 2 of the floor drain to protect safety and sanitation.
