Description

Shower with sensor switch

Technical field

The present invention relates to sanitary ware, and more particularly to a shower having an inductive switch.

Background technique

The inductive faucet is already a mature product. The main principle is to sense whether an object such as the user's hand is close by the infrared sensor, and then open the faucet according to the induction result to drive the solenoid valve. Compared with ordinary faucets, in addition to being more convenient to use, its outstanding advantage is that it is suitable for public use, which can greatly reduce the possibility of cross-infection of diseases.

Showers are also one of the most important sanitary appliances, but there are no inductive showers on the market or in the industry. People can only use manual switches when using showers, which brings great Inconvenience. For example, during the bathing process, the user first wets the body, then applies the body lotion to the body, then rinses the body foam with water, and finally wipes the body with a towel. In the process, the user needs twice. The shower is turned on and off. When the second flowering is sprinkled, the user's hand is covered with foaming of the bathing liquid, which will stain the switch of the shower, and the shower switch must be cleaned.

The reason why the inductive showers are rejected is mainly because the designers in the industry have an inertial thinking that people often trigger in the case when they do not want to take a bath and go to the shower before going to the shower. The inductive shower opens, causing unnecessary troubles such as getting wet clothes. Therefore, the designers of the industry have never invested research into the structural design of the inductive shower, and people have not been able to enjoy the convenience of the inductive shower. However, this kind of trouble is actually easy to solve, for example, setting a manual switch to the sensor, turning off the sensor when not normally taking a bath, or turning the sensor in a direction that is not easily blocked when not taking a bath.

In the foregoing shower with an inductive switch, the power supply device is a battery.

In the foregoing shower with an inductive switch, the power supply device is a micro-generator and an impeller for driving the micro-generator, and the impeller is disposed in the water flow channel.

The water flow passage forms a radially reduced injection port on the side of the impeller opposite the water inlet.

The shower having the inductive switch has a body including a casing having a downward opening and a supporting casing, wherein a central portion of the casing is provided with a fitting groove, and a water inlet joint is installed in the fitting groove, and the supporting casing is Mounted under the mounting groove, the cover is mounted under the support housing, and a space between the outside of the support housing and the inside of the housing forms an electrical component cavity, the power supply device, a solenoid valve, a circuit board, and The infrared sensor is installed in the electrical cavity of the electrical device.
