Description

Self-sealing deodorant floor drain

technical field

The invention belongs to the technical field of fixed buildings, and relates to a floor drain, in particular to an automatic sealing type deodorant floor drain.

Background technique

With the improvement of people's quality of life, the demand for home decoration materials is also increasing. Floor drains are one of the most common decoration accessories, which are installed on the ground surfaces of kitchens, bathrooms and balconies. In order to achieve the purpose of deodorizing and preventing insects, a sealing device is arranged in the existing floor drain, and the sealing device seals the floor drain after the drainage of the floor drain is completed, so as to achieve the purposes of deodorizing and preventing insects. The deodorant floor drain of this structure has a complicated structure and inconvenient installation, and the water outlet of this floor drain is relatively small, which is easily blocked by impurities, and the deodorant effect is not good, which brings great inconvenience to people's lives.

For this reason, people have carried out long-term exploration, have proposed various solutions, and some have also applied for a patent. For example, the Chinese patent literature discloses a self-sealing floor drain [authorized announcement number: CN2856198Y], which includes a housing on which a movable panel is arranged, and also includes a leakage cylinder, which is installed on the inner wall of the housing and cut into the The inner wall of the shell is sealed and fit, and a bracket is arranged at the water inlet at the upper end of the leaking tube. The control connecting rod is telescopic up and down. The inner hole of the sleeve supports and guides the control connecting rod. The upper end of the control connecting rod is provided with a moving magnet that attracts the opposite sex with the static magnet. The other end is connected with a sealing cover. The shape of the sealing cover and The size matches the shape and size of the drain outlet of the drain tube, and the sleeve is provided with a bottom dead center stop structure of the control connecting rod.

Although the floor drain of this structure has the advantages of tight sealing and smooth drainage. But the lower surface of the support in the sleeve is provided with a static magnet, so that the sewage entering the sleeve directly contacts with the static magnet. When the sewage flows through the static magnet, the iron filings or magnetic substances contained in the sewage are adsorbed on the surface of the sleeve by the static magnet, and accumulate more and more over time, so that the mouth of the sleeve is blocked and the floor drain loses the function of deodorization. Moreover, the bracket arranged in the sleeve is also easy to hang sundries such as hair, and has the characteristics of being difficult to clean. Furthermore, the structure of the floor drain is relatively complicated, and applying the magnet to the floor drain will increase the cost of the floor drain.

Contents of the invention

The purpose of the present invention is to solve the above-mentioned problems in the existing technology, and propose an automatic sealing type deodorant floor drain with compact structure, good sealing performance and good deodorizing effect.

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

The self-sealing deodorant floor drain includes a cylinder body with a water inlet and a water outlet, a water-permeable panel is provided at the water inlet of the cylinder body, and a leak core is provided inside the cylinder body, and the leak core has the same structure as the above-mentioned The water passage through which the water outlet is connected, is characterized in that there is a water storage chamber for forming a water seal between the leaking core and the cylinder body, and the water storage chamber communicates with the above-mentioned water inlet through a liquid inlet passage, In addition, the water storage chamber communicates with the above-mentioned water passage through a liquid outlet channel, and an opening member that can close the liquid outlet channel by gravity or open the liquid outlet channel by buoyancy is provided in the liquid outlet channel.

When the self-sealing deodorant floor drain is working, the sewage enters the water storage cavity through the panel through the water inlet channel, so that the sewage in the water storage cavity gradually rises, and the sewage has a certain buoyancy on the opening part during the rising process, so that The opening part moves upward along the liquid outlet channel, and at this time the liquid outlet channel is opened, and the sewage can flow into the liquid passage through the liquid outlet channel, so as to achieve the purpose of sewage discharge. When the sewage stops, a water seal is formed in the water storage cavity, which can prevent odors and the like from entering the room. When the water in the water storage cavity dries up, the opening part seals the liquid outlet channel, which also achieves the deodorizing effect. This structure has the double anti-odor effect of the opening part and the water seal, and the anti-odor effect is better.

In the above-mentioned self-sealing deodorant floor drain, the lower part of the cylinder is retracted inwardly to form a support part matched with the lower part of the leakage core, and an annular step is provided at the support part, and the above-mentioned water outlet is located at at the support portion.

The core body arranged at this place can form a water storage chamber with the cylinder body, while the sleeve body and the cover body make the water in the water storage chamber form a water seal to prevent odor from overflowing. The cover body is arranged on the upper end of the sleeve body and covers the upper opening of the sleeve body, so as to isolate the odor in the core body.

In the above-mentioned self-sealing deodorant floor drain, the opening member is an annular gasket, the gasket is sleeved on the outside of the core, and the gasket can move up and down along the core .

In the above-mentioned self-sealing deodorant floor drain, the density of the sealing gasket is smaller than that of water. In the presence of a water seal, the sealing pad floats on the water seal, and the water seal acts as a deodorizer at this time; The liquid channel moves downward to seal the liquid outlet channel.

In the above-mentioned self-sealing deodorant floor drain, the upper part of the core body is provided with a through hole communicating with the liquid outlet channel and the water outlet channel.

In the above-mentioned self-sealing deodorant floor drain, a filter screen is provided between the sleeve body and the cylinder body. The filter screen can filter the large dirt in the sewage and prevent it from clogging the sewer pipe.

In the above-mentioned self-sealing deodorant floor drain, the filter screen and the above-mentioned cover body are integrally constructed.

In the above-mentioned self-sealing deodorant floor drain, the sleeve body is fixedly connected to the core body through connecting ribs. The connection rib also serves the purpose of preventing the gasket from coming off.

In the above-mentioned self-sealing anti-odor floor drain, the panel is connected to the water inlet of the barrel by clamping.

In the above-mentioned self-sealing deodorant floor drain, an annular slot is provided at the water inlet of the cylinder, and the edge of the panel has a shoulder corresponding to the annular slot, and the annular slot is also There is an opening for the shoulder to pass through.

In the above-mentioned self-sealing deodorant floor drain, the sealing gasket is made of plastic material.

Compared with the prior art, the self-sealing deodorant floor drain has the following advantages:

1. There is a water storage chamber between the leaking core and the cylinder body. The water storage chamber can form a water seal. Under normal circumstances, it can prevent the odor in the sewer pipe from entering the room and ensure the cleanliness of the room.

2. There is an opening piece in the liquid outlet channel. When the water seal dries up, the opening piece can abut against the connecting rib and seal the liquid outlet channel to prevent the odor in the sewer pipe from entering the room and ensure the safety of the room. clean.

3. The leaking core and the cylinder are relatively independent. When the leaking core is damaged, the leaking core can be replaced to reduce costs; the self-sealing deodorant floor drain has a compact structure, and a sealing ring is provided between the core and the cylinder. Its sealing effect is good, and the double anti-odor structure is adopted to prevent the odor from entering the room, and the anti-odor effect is better.
