Flushing device

Abstract

A flushing device comprises a control module, a solar cell and a rechargeable cell. The control module is used for controlling the flushing device to operate. The rechargeable cell is connected with the solar cell in parallel at a power output end. The power output end is electrically connected with the control module to provide power to the control module.

Description

technical field [0001] The invention relates to a flushing device, in particular to a solar flushing device which uses a solar battery or a rechargeable battery as a power supply source for a holding electromagnetic valve. Background technique [0002] Traditional inductive flushing devices are used in inductive urinal flushers or inductive faucet flushers, etc. They are designed and developed in accordance with the specifications of the mains power supply, but DC power is still used in the electronic control components, so the use of electricity requires Converting AC to DC can be used by electronic control circuits. A set of transformers is generally required for voltage conversion. The use of transformers will result in huge energy consumption (loss of heat or magnetic energy). If this AC product is used with a solenoid valve It belongs to the non-maintaining solenoid valve, and the energy consumption of the solenoid valve is very considerable when it is opened for a long...

AI Technical Summary

Problems solved by technology

[0002] Traditional inductive flushing devices are used in inductive urinal flushers or inductive faucet flushers, etc. They are designed and developed in accordance with the specifications of the mains power supply, but DC power is still used in the electronic control components, so the use of electricity requires Converting AC to DC can be used by electronic control circuits. A set of transformers is generally required for voltage conversion. The use of transformers will result in huge energy consumption (loss of heat or magnetic energy). If this AC product is used with a solenoid valve It is a non-holding solenoid valve, and the energy consumption of opening the solenoid valve for a long time is very considerable

[0003] The above-mentioned AC flushing equipment requires a traditional transformer, resulting in high cost and large volume

Furthermore, the assembly will be more difficult and complicated than other products of the same type. In addition, the power line must be reserved in the building when the product is installed, so that the product cannot be popularized.

[0004] Regarding the inductive flushing device with DC power supply, the power supply of this series of products is DC, which are all designed to be provided by batteries. The product installation is very convenient and fast, but the product life will be quite limited due to the battery voltage. The battery needs to be replaced within a short period of time to continue the function of the flushing device, and therefore too many waste batteries are produced, causing pollution and load on the environment

[0005] If you use a rechargeable battery that can be repeatedly charged and discharged, you still cannot get rid of the shortcomings of the inductive flushing device with AC power. You must have a transformer for the charger, and the assembly will naturally be more difficult and complicated than other products of the same type. At the same time, the product The power line must still be reserved in the building during installation, so that the product cannot be popularized

[0006] In addition, because the battery voltage of DC power supply inductive flushing device products is too low, the solenoid valve used together is an energy-saving holding solenoid valve. The disadvantage of this kind of solenoid valve is that when the operation fails (power failure or malfunction), and There is no effective debugging method. If the valve of the faucet controlled by the solenoid valve is not closed, it will cause serious waste of water resources and difficulties in dealing with the aftermath.
