Description

drainage pipe dredging device

The invention relates to a drainage pipe, in particular to a drainage pipe dredging device.

Generally, when the drainage pipe is blocked by foreign matter and needs to be dredged, a water pipe is usually inserted into the drainage pipe and washed with a high-pressure water column. After the foreign matter is displaced by the high-pressure impact force of the water column, the drainage pipe can be dredged.

However, when using the high-pressure water column to dredge the drainage pipe, although the water column is pressurized, because a lot of water has accumulated in the drainage pipe, the pressurized water column will reduce the impact force after contacting the accumulated water, so when the blocked When the position is deep or the foreign matter is attached to the pipe wall of the drainage pipe, the high-pressure water column still cannot effectively displace the foreign matter, so the drainage pipe cannot be effectively dredged.

In addition, in the process of dredging the drainage pipes, the accumulated water is often affected by the impact of the high-pressure water column, which will cause the pressure to increase and spray back to the drain. This will not only affect the dredging operation, but also cause the accumulated water to splash The surfaces around the drain openings create a messy environment and are in urgent need of improvement.

In addition, there are drainage grilles fixed above some drain outlets, so it is impossible for the water pipe to extend into the drain pipe for dredging. Different water pipe dredging agents must be used for different materials, and sometimes the user does not know the material of the blocked foreign matter, so it is very inconvenient.

It is therefore an object of the present invention to provide a device for unclogging drains which overcomes at least one of the disadvantages of the prior art.

Pressurized water and air are suitable for entering the drainage pipe through the at least one drainage inlet, the drainage outlet and the liquid discharge chamber to dredge the drainage pipe. The at least one connection chamber communicates with the at least one second opening and corresponds to the surrounding portion. When pumping air to the first opening, the gas pressure of the at least one connecting chamber can be reduced so that the connecting body is airtightly connected to the surrounding portion.

The effect of the present invention is that by setting the connecting body around the drain port, in addition to avoiding the splashing of water sprayed back to the surrounding part during dredging, since the connecting body can be airtightly connected to the surrounding part, therefore When the drain grill is fixed above the drain, the drain dredging device can also be fixed above the drain to allow pressurized water and air to pass through to dredge the drain.
