Description

Shower with sensor switch

technical field

The invention relates to a bathroom appliance, in particular to a shower with an induction switch.

Background technique

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

The shower is also one of the important bathroom appliances, but there is no inductive shower on the market or in the publications of the industry. When people use the shower, they can only be carried out by manual switch, which brings great inconvenience to people. the inconvenience. For example, in the process of taking a bath, the user first wets the body, then smears the body with the body wash, then rinses the foam of the body wash with water, and finally dries the body with a towel. In this process, the user needs to wash the body twice. When the shower is turned on and off, when the shower is showered for the second time, the user's hands are covered with body wash foam, which will dirty the switch of the shower, and the shower switch has to be cleaned in addition.

The reason why the induction shower is rejected is mainly because the designers in the industry have a kind of inertial thinking, thinking that people often enter the bathroom and walk to the shower when they don’t want to take a shower, and it is easy to trigger it when they don’t want to. The induction shower is turned on, causing unnecessary troubles such as getting wet clothes. Therefore, designers in the industry have never devoted their research efforts to the structural design of the induction shower, and so far people cannot enjoy the convenience of the induction shower. However, this kind of trouble is actually very easy to solve, for example, set a manual switch for the sensor to turn off the sensor when not taking a bath; or turn the sensor to a direction that is not easily blocked by people when not taking a bath.

Contents of the invention

The present invention provides a shower with an induction switch, the main purpose of which is to overcome the disadvantage that the switch of the existing shower must be operated manually, which is extremely inconvenient to use.

The present invention adopts the following technical solution: a shower with an inductive switch, comprising: a body and a cover connected to the body, the body is provided with a water flow channel, the cover is set at the water outlet of the water flow channel, and the cover There is a water spray hole connected with the water flow channel, and it also includes: a solenoid valve installed in the body to control the on-off of the water flow channel; an infrared sensor is located in the body, and the infrared sensor The face cover faces the same direction; the circuit board and the power supply device for supplying power to the circuit board are installed in the body, and the circuit board controls the solenoid valve to work according to the signal of the infrared sensor.

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

In the aforementioned shower head with an induction switch, the power supply device is a micro-generator and an impeller driving the micro-generator to generate electricity, and the impeller is arranged in the water flow channel.

The water flow channel forms a jet port with reduced radial size on the side of the impeller close to the water inlet.

The aforementioned shower head with an induction switch has a body that includes a shell with a downward opening and a support shell. An assembly groove is provided at the center of the top of the shell, and a water inlet connector is installed in the assembly groove. The support shell Installed under the assembly groove, the face cover is installed under the supporting shell, the space between the outside of the supporting shell and the inside of the shell forms an electrical storage cavity, the power supply device, solenoid valve, circuit board and The infrared sensor is installed in the electric appliance container.

From the above description of the structure of the present invention, it can be seen that compared with the prior art, the present invention has the following advantages: the present invention overcomes the inertial thinking of designers in the industry, and applies the inductive switch to the shower for the first time, enabling people to use the shower During the process, there is no need to manually switch the shower, which greatly facilitates people's use.
