Sensing flush device of bathroom sanitary fittings

Abstract

The invention discloses a response water filling device of bathroom sanitary fittings. The response water filling device comprises a drain valve, an inlet valve and at least one response driving mechanism. At least one row of dewatering buttons is arranged at the top end of the drain valve, the response driving mechanism comprises an electronic control valve, a fluid-valve, an execution lever and an inductor, an output end of the inductor is connected with an input end of an electronic control valve, a water inlet of the electronic control valve is communicated with a water inlet cavity of the inlet valve, a water outlet of the electronic control valve is communicated with a water inlet of the fluid-valve, and the fluid-valve is provided with a piston rod. The execution lever is ratatably installed in the drain valve, one end of the execution lever is a touch and pressing key of the dewatering button and is contacted with the dewatering buttons, and the other end of the execution lever is a controlled end and is contacted with the piston rod of the fluid-valve. The response water filling device is simple in structure, strong in generality, particularly suitable to transformation from a traditional top pressing closestool to a touch-free response-type water filling closestool, capable of responding and automatically flushing water, capable of avoiding cross-infection of bacteria and vertical plane close distance response and capable of avoiding aimless water filling and the like.

Description

technical field [0001] The invention relates to a flushing device for sanitary ware, in particular to an induction flushing device for sanitary ware. Background technique [0002] At present, the sanitary ware in the prior art, including toilets and some squatting pans, mainly use the water tank accessories to realize the flushing process, and most of them use manual pressing of buttons to drive the water tank accessories to complete the flushing action, which is not only laborious and time-consuming, but also The buttons are prone to failure due to long-term acceptance of different pressing intensities and are difficult to press and drain. In addition, in the prior art, manual pressing is used to control flushing, which is also likely to cause cross-infection of bacteria from human hands. In the prior art, there are also a small number of intelligent flushing devices with the function of induction and automatic flushing, but they all have the following defects: 1. Usually,...

Problems solved by technology

[0002] At present, the sanitary ware in the prior art, including toilets and some squatting pans, mainly use the water tank accessories to realize the flushing process, and most of them use the way of manually pressing the buttons to drive the water tank accessories to complete the flushing action, which is not only laborious and time-consuming, but also The button is prone to failure due to long-term acceptance of different pressing intensities, and it is difficult to press and drain

In addition, the existing technology uses manual pressing to control flushing, which may easily cause cross-infection of bacteria from hands

In the prior art, there are also a small number of intelligent flushing devices with the function of induction and automatic flushing, but they all have the following defects: 1. Usually, a motor is used to directly drive the drainage device. As a power supply, there are potential safety hazards; 2. The sensing range of the sensing device is generally large, and the sensing distance is also relatively long. Once the user appears within the sensing range, it will automatically flush whether it needs flushing or not

Therefore, the intelligent flushing device of the prior art is prone to blind flushing, resulting in a great waste of water resources
