Do you have any cheap and easy ways to get rid of the smell wafting from the toilet to the classroom

The odor generated by the exhaust fan can be solved by installing a check valve (similar to the flue check valve in the kitchen), so as to prevent the air in the air duct from flowing back into the bathroom. Generally, when the developer delivers the house, the check valve will be installed at the air duct mouth, that is, the check valve, the gas can only flow from the bathroom to the pipe, can not be returned, if the developer does not install, you must install it when decorating your home, it is only a few dozen dollars a, you can often ventilate.

The floor drain is not right, the floor drain looks like an inconspicuous little thing, but it is definitely not a place to cut corners. The smell generated at the floor drain is largely caused by the floor drain itself, and the depth of the water trap is not enough, and the smell will rise up. In other words, as long as you buy a good floor drain, you can solve this problem.

In addition to fast drainage, a qualified floor drain must also have the functions of anti-bacteria, anti-odor, anti-clogging and anti-backwater.

The wall and floor tiles are hollow and the water is stored, and when the tiles are laid on the bathroom floor, due to the construction is not in place, after the cement under the tiles is dried, a large gap appears between the cement layer and the tiles, and the sound of "empty" is made when struck with a hard object, which is called "empty drum". When taking a bath, the water will flow into the hollow drum between the tile and the cement layer along the gap of the tile, and the waterproof layer is below the cement layer, so it is difficult for the water in the hollow drum to evaporate naturally, and it will form stagnant water that is difficult to dissipate after a long time, and finally become stinky. Therefore, it is recommended that when you decorate, you must do a good job of waterproofing and tile laying in the bathroom, otherwise, it may become a big problem in the later stage.

The drain under the sink is not well sealed, or even not sealed at all. In addition to the sewer opening, the water pipe should also have a trap. The purpose of the trap is to use the U-shaped arc to form a sealed section of water in the pipe, and this water can isolate the odor in the sewage pipe.

The bathroom is the easiest place to hide dirt and dirt, especially in summer, even if the bathroom in some people's homes is clean, there is always a lingering strange smell, and some people are enduring the trouble of small flying insects in the bathroom! The most intuitive occurrence of peculiar smell is some sanitary dead corners in the bathroom, such as: the gap between the bathroom cabinet and the ground, the gap on the back of the toilet, etc.

These dead corners of the bathroom are not easy to clean, and at the same time, they are easy to ignore in daily cleaning, coupled with the dampness of the bathroom, the dander, hair and other debris accumulated in the dead corners breed bacteria and produce odors.

T-shaped floor drain and deep water bend floor drain are upgraded versions of U-shaped floor drain, and the sealing is often achieved by gravity, springs, magnets and other mechanical devices. When there is a flow of water passing by, gravity presses and automatically opens; When no water flows through, it closes automatically. Therefore, the deep water bend floor drain can prevent odor and at the same time, it can better block the small flying insects parasitic in the sewer than the U-shape.

U-shaped floor drain is a water-sealed floor drain, which relies on the tightness of water to seal the sewer odor overflow. In the presence of water, the anti-odor effect is obvious, but if the trap dries up, the U-shaped floor drain becomes a vent, and the odor in the sewage system can pass through unimpeded.

The drain pipe is directly inserted into the sewer pipe, and there is no seal at the interface; The drain pipe does not have an S-shaped trap water seal, or there is a sealing device in the drain pipe, but the seal fails due to foreign objects such as hair; Residues such as hair adhere to the walls of drain pipes, and after a long period of time, they deteriorate and form a foul odor.

If the toilet flange is not of good quality or loose, then the excrement cannot all flow into the sewer pipe, and may leak out from the side, which is the source of the odor.

The S-shaped structure can effectively store water and prevent the smell of dirty water from turning up. The built-in anti-odor valve will only open when there is underwater flow, and the rest of the time it is closed.
