Description

self-starting floor drain

technical field

The utility model belongs to the technical field of drainage pipe fittings, in particular to a self-starting floor drain.

Background technique

The existing floor drain is basically composed of a shell and a water seal cover. The shell is provided with an annular water seal groove. The water seal cover is in the shape of an inverted cup. The cup body is inserted into the middle of the water seal groove. In the tank, a circumferential turning water bay will be formed to prevent the odor in the underground pipeline from escaping and achieve the purpose of deodorization. But there are two problems in it: the one, when there is no water inflow for a long time, the water level in the water seal tank is not high enough or dry, and there is no effect of water seal, so that the foul smell and small mosquitoes in the underground pipeline will pollute the indoor environment.

Contents of the invention

The technical problem to be solved by the utility model is to provide a self-starting floor drain aimed at the deficiencies of the above-mentioned prior art, which can effectively prevent the indoor environment from being polluted by odor and small mosquitoes in the underground pipeline.

The technical solution adopted in the utility model is: a self-starting floor drain, including a floor drain body, the floor drain body is a cylindrical shell, and a trumpet-shaped water inlet pipe is fixedly connected to the side wall of the upper part of the floor drain body. A filter screen is provided between the water inlet pipe and the floor drain body, the upper end of the floor drain body is sealed, and several partitions are arranged between the water inlet pipe and the floor drain body, and the partitions connect the water inlet pipe and the floor drain body. The area is divided into a plurality of hydrophobic spaces, each hydrophobic space is provided with a hydrophobic hole on the side wall of the floor drain body, and each hydrophobic space is provided with a floating ball capable of blocking the hydrophobic hole.

Preferably, the upper edge of the water inlet pipe is flush with the upper edge of the floor drain body.

Preferably, the upper edge of the separator is in contact with the filter net.

The beneficial effect of the utility model is that: when water flows into the water inlet pipe, under the buoyancy of the floating ball, the drain holes are turned on, and the floor drain is automatically opened to drain water, and the water flows into the floor drain and finally enters the downpipe; when there is no water in the water inlet pipe When it flows in, the floating ball will block the hydrophobic hole under its own gravity, thereby isolating the downpipe and the indoor space, thereby preventing the odor and mosquitoes in the downpipe from entering and polluting the indoor environment.

Fig. 2 is a sectional view of A-A in Fig. 1 .

In the figure: 1. Floor drain body; 2. Water inlet pipe; 3. Filter screen; 4. Partition plate; 5. Hydrophobic hole; 6. Floating ball; 7. Hydrophobic space.

Detailed ways

The utility model will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1 and 2, a self-starting floor drain includes a floor drain body 1, the floor drain body 1 is a cylindrical shell, and a horn-shaped inlet is fixedly connected to the side wall of the upper part of the floor drain body 1. Water pipe 2, the upper edge of the water inlet pipe 2 is flush with the upper edge of the floor drain body 1, a filter screen 3 is provided between the water inlet pipe 2 and the floor drain body 1, and the upper end of the floor drain body 1 is sealed, so Several partitions 4 are arranged between the water inlet pipe 2 and the floor drain body 1, and the upper edge of the partition board 4 is connected with the filter screen 3, and the partition board 4 connects the water inlet pipe 2 and the floor drain body 1. The area is divided into a plurality of hydrophobic spaces 7, and the side wall of the floor drain body 1 corresponding to each hydrophobic space 7 is provided with a hydrophobic hole 5, and each hydrophobic space 7 is provided with a hole that can block the hydrophobic hole 5. Float6.

When water flows into the water inlet pipe 2, under the buoyancy of the floating ball 6, the drainage hole 5 is turned on, and the floor drain is automatically opened to drain water, and the water flows into the floor drain and finally enters the downpipe; The ball 6 blocks the hydrophobic hole 5 under the action of its own gravity, thereby isolating the sewer pipe and the indoor space, thereby avoiding foul smell and mosquitoes in the sewer pipe from entering and polluting the indoor environment.

The above is only a preferred embodiment of the utility model, so the scope of implementation of the utility model cannot be limited with this, that is, the equivalent changes and modifications made according to the patent scope of the utility model and the content of the specification should still belong to the utility model. Within the scope covered by the utility model patent.
