Water pipe cleaning device

The invention relates to a cleaning device, in particular to a water pipe cleaning device connected to an indoor water pipe.

With the development of industry, the continuous progress of the society has led to environmental pollution, which indirectly or directly affects the quality of our water. Water can be used not only for people to drink, but also for cooking and cleaning purposes. The water is pumped into the water tower by the motor, and the water pipe is connected between the water tap and the water tower. When the water tap is turned on, the water stored in the water tower is sent to the water tap through the water pipe for the people to use.

Since the water itself contains impurities and minerals in addition to water, people will fix the water tower, but never thought about cleaning the water pipe. The water is more or less entrained in the process of transporting it to the faucet via the water pipe. The dirt is in the pipe wall of the water pipe, and the pipe diameter of the water pipe is small, the plane flows, and the curve is bent. It is relatively easy to block the scale. After a long time of use, the sludge, algae, germs, and various heavy metals contained in the water , will be attached to the pipe wall of the water pipe, coupled with the corrosion caused by the long-term use of the water pipe, the degree of dirty can be imagined, the water pipe wall thickened due to dirt and dirt will not only make the water pipe The amount of water is reduced. When people use the water flowing through these pipes as drinking or cleaning water, they will be absorbed from the human skin to the body bit by bit. The accumulation of skin will cause skin lesions and endanger the health of the human body. In view of this, cleaning water pipes has become a very important matter.

Referring to Fig. 1, a new type of pipe cleaning machine of the Republic of China No. M385409, which discloses a conventional water pipe cleaning machine, which comprises a gas connection port 11 connected to an external air compressor A. By inputting a high-pressure gas source, a medicine connection port 12 is connected with a liquid storage tank B of an external storage medicine to input a line cleaning agent, and the medicine is outputted from an output port 13 with a high-pressure gas source, and is pumped through a pumping motor 14.

By driving the air into the water pipe, the water pipe is used to wash the water pipe wall to remove Dirt attached to the wall of the water pipe. In the process of operation, it is necessary to ensure that the pressure is constant. During the actual operation, the operating state of the air compressor A will also be affected by factors such as the diameter of the pipe to be cleaned and the voltage stability, and the original setting cannot be output. The ideal pressure, which in turn reduces the water hammer effect, will not only lengthen the cleaning time, but also increase the waste of water resources, and it is impossible to achieve the purpose of cleaning the pipeline.

Moreover, the pipe cleaning machine will generate the pressurized water or the chemical flow back to the air compressor A every time after flushing or interrupting the closing of the water, forming a blockage of the pipeline, which will not only cause water flow and cleaning. The continuous output waste of the agent, high-pressure air, etc., will cause the air compressor A to be damaged and reimbursed, which is not worth the loss. If the drug is used as a means of cleaning the water pipe, it will also cause the problem of the drug residue and the chemical corrosion of the water pipe wall, and pollute the water flowing through the water pipe. Not only can the quality of the water be improved through the cleaning water pipe, but the water content can be increased. The safety of the drug residue problem is indeed open to question.
