Description

Anti-fouling automatic flushing channel system

technical field

The utility model relates to water pipe accessories, in particular to an anti-pollution automatic flushing channel system.

Background technique

The existing water pipe accessories mainly include tee pipes, angle valves, faucets, water purification tees, etc., and there is generally no filter screen inside, so that the equipment connected to them (such as water purifiers, water heaters, etc.) tends to accumulate large particles in tap water Substances will have a certain negative impact on the equipment, such as: tap water containing large particles entering the water purifier will reduce the life of the primary filter element of the water purifier. In addition, the existing water pipe fittings do not have the function of sensing water flow signals, and are connected to electrical equipment such as water purifiers, which limits the functions of the electrical equipment. Also, the existing water pipe fittings are either integral hardware die-casting, which is too costly; or plastic injection molding, which has too low strength and is easy to slip when the connecting thread is installed, especially the external connecting thread, which is easier to slip.

On the other hand, by setting the metal layer on the outer surface, the sense of grade of the runner system can be improved, but the cost is lower than that of all-metal products.

As the best solution, a total flow sensing device is also provided in the water outlet channel, so as to detect the water flow signal and the water output of the water outlet channel. At the same time, through the data measured by the total flow sensing device, combined with the control circuit, when one end is used for a period of time, the control circuit can send out an alarm message to remind the user to open the sewage control valve, or when the sewage control valve is a solenoid valve or electric valve, directly control It is opened to realize the purpose of automatically cleaning the filter screen without disassembling the filter screen.

There is also at least one secondary flow sensing device outside the flow channel body, the total flow sensing device and the secondary flow sensing device are electrically connected to a control circuit respectively, the water outlet channel communicates with the water inlet end of the water purifier, and the secondary flow rate The induction device communicates with the water outlet of the water purifier. The control circuit compares the water consumption information obtained by the auxiliary flow sensing device with the water consumption information of the total flow sensing device. If the water consumption obtained by the auxiliary flow sensing device is less than the water consumption of the total flow sensing device, it indicates that the water purifier may leak , It is necessary to remind the user to open the sewage outlet or automatically control the opening of the sewage outlet for pressure relief to protect the water purifier.

The beneficial effects of the utility model are as follows:

There is a filter between the outlet channel and the flushing channel of this anti-fouling automatic flushing channel system, so that the water from the outlet channel can be preliminarily filtered. At the same time, since the flushing channel has a sewage outlet, when the sewage outlet is opened, the flow channel At least a part of the inside of the system flows out from the sewage outlet, and the water flow inside the flow channel system scours the surface of the filter screen facing the flushing channel, so that the accumulated filter material on the surface is washed away and then flows out through the sewage outlet, so that automatic cleaning can be realized without disassembling the filter screen The purpose of the filter screen, and, as long as the filter screen is not damaged, the filter screen does not need to be disassembled and replaced, which makes the use and maintenance of the product convenient.
