Description

Water valve controller

Technical Field

The utility model relates to the technical field of water valves, in particular to a water valve controller.

Background

Along with the improvement of living standard and the development of technology, electronic bathroom products are also rapidly developed, such as a faucet with a water valve controller with a non-contact sensing device, and a user can control the opening and closing of a water valve by only extending a handle into a sensing area of the controller sensing device or waving the sensing device, so that dirt can be prevented from being transmitted through a touch handle, and meanwhile, the use experience of the product is improved. However, in order to avoid false triggering of the sensing device due to different installation environments, some parameters (such as sensing area and sensitivity) of the sensing device in the controller need to be adjusted according to the installation environments and installation positions, for example, when the sensing device is installed near the water inlet of the faucet and far from the water outlet of the faucet, the sensitivity of the sensing device needs to be set higher; when the sensing device is installed toward the interior of the basin, the sensitivity is reduced to avoid false triggering due to sensing of the wall of the basin. Currently, two main parameter adjustment modes of a non-contact water valve controller sensing device are adopted, one is that a manufacturer adjusts products batch by batch through an internal circuit or a program of the sensing device during production, the method has the advantages of simplicity, easiness and low cost, and the defect that the use environment must be known in advance and corresponding adjustment measures must be made before production, the parameters of the sensing device of the water valve controller after leaving the factory cannot be modified, and the method can seriously influence the flexibility of installation of the water valve controller; the other is that the manufacturer sets up some adjustable spare parts such as adjustable resistance in the controller to expose the adjustment end of adjustable spare part outside the controller, can supply the user to adjust through simple instrument, this kind of design's advantage is that the installation flexibility is better, and the shortcoming has influenced induction system's outward appearance and has reduced waterproof performance, uses in humid environment for a long time when the product, appears that adjustable spare part wets malfunctioning and leads to the problem that the setting parameter appears disorder easily.

Therefore, there is a need to provide a new solution to overcome the above-mentioned drawbacks.
