Description

Technical Field

[0001] The utility model relates to the technical field of bathroom products, in particular to an automatic pipeline flushing device. Background Art

[0002] Drainage pipes in various buildings may not be used for a long time, such as schools, hotels, stadiums, etc., which may be unused for a long time, and private houses may be in a long-term absence, such as business trips, vacations, etc. In this case, the water in the pipe is stagnant for a long time and the water does not flow. In this case, if we do not use the water pipes for a long time, the water in the pipe system is prone to breed bacteria. The pollution problem is particularly present in buildings that are not used for a long time. In this case, the so-called sanitary flushing is used to regularly flush the water pipe system to avoid water pollution caused by stagnation. Therefore, a device that can be used to automatically flush the pipe system is proposed. For example, patent document EP1964983B1 discloses a regular water discharge structure, but the automatic control valve of this device and the water in the water tank are in the same box, because there is always a certain amount of water retained in the water seal, so that the components of the automatic control will have water vapor, which will affect the service life of the electronic components and cause the risk of misoperation.

The waterproof cover 4 may not be provided with a window 43.

[0038] The utility model has the following working principle:

[0039] The control valve 3 for controlling the water inlet is arranged outside the live water tank 2, and a water-blocking cover 4 is arranged outside the live water tank 2 to separate the water vapor from the control valve 3 and the electronic control components such as the controller, so as to avoid the influence of the drainage water vapor on the control valve 3 and other electronic components. At the same time, a manual valve 5 is arranged on the water inlet pipe 1 at the front end of the control valve 3, and the wrench 51 of the manual valve 5 in the open state will block the fixing part 32 of the control valve 3, which can avoid the liquid splashing caused by the disassembly and assembly of the control valve 3 when the water inlet is not closed, causing damage to the controller and the control valve 3, and is convenient for the replacement and repair of the control valve 3. When it is necessary to drain the water, the control valve 3 is opened (the manual valve 5 is in the normally open state), and the water flow in the water inlet pipe 1 flows through the manual valve 5 and the control valve 3, flows out through the outlet 31 of the control valve 3 and falls on the retaining net 6, and then disperses the water flow through the retaining net 6 and enters the first accommodating chamber 21, and then flows into the drain pipe through the water seal between the water seal cover 7 and the drain pipe, and then flows into the sewer pipe to flush the pipe.
