DETAILED DESCRIPTION

[0023] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings:

[0024] like Figure 1-2 As shown,

[0025] An induction water switch system comprises an installation shell 1, a power generation device 2, an energy storage device 3, a switch control device 4, an induction control device 5, a water inlet 6 and a water outlet 7; the power generation device 2, the energy storage device 3, the switch control device 4, the induction control device 5, the water inlet 6 and the water outlet 7 are respectively arranged on the installation shell 1; the water inlet 6 is communicated with the switch control device 4, the switch control device 4 is communicated with the power generation device 2, and the power generation device 2 is communicated with the water outlet 7; the power generation device 2 is electrically connected to the energy storage device 3, the energy storage device 3 is electrically connected to the switch control device 4 and the induction control device 5 respectively, the power generation device 2 is used to store the generated electric energy in the energy storage device 3, and the energy storage device 3 is used to power the switch control device 4 and the induction control device 5; the switch control device 4 adopts a pulse solenoid valve, the induction control device 5 is electrically connected to the pulse solenoid valve, and the induction control device 5 is used to control the opening or closing of the pulse solenoid valve; in this embodiment, by providing the power generation device 2, the energy storage device 3, the switch control device 4 and the induction control device 5, the induction control The device 5 can sense human body signals and control the opening of the switch control device 4, so that water flows in the water flow cavity 8 and passes through the impeller 10, which can drive the impeller 10 to rotate, thereby enabling the generator 9 to generate electrical energy. The electrical energy is stored in the energy storage device 3 through rectification and voltage stabilization, and continues to power the switch control device 4 and the induction control device 5, thereby circulating; the switch control device 4 adopts a pulse solenoid valve, which uses a truly electronically controlled method and can achieve the function of inching, that is, after the induction control device 5 senses the human body signal, it will instantly control the pulse solenoid valve to open. Compared with a mechanical control switch, it can further save energy consumption, because a mechanical control switch is generally composed of a motor and a valve, and the valve is controlled to rotate by a motor to open the switch. However, the process of the induction control device 5 controlling the motor takes more time, and the process is power-consuming. For example, it takes 3 seconds for the induction control device 5 to control the motor, while in this application, the induction control device 5 controls the pulse solenoid valve inching process for only about 0.1 seconds. Therefore, after comparison, the pulse solenoid valve used in this application can save more electrical energy and further ensure that energy replenishment is greater than energy consumption.

[0026] As a preferred embodiment, the sensing control device 5 adopts a pyroelectric infrared sensor. By adopting the pyroelectric infrared sensor, the pyroelectric infrared sensor has a better sensing effect, sensitive sensing, a larger sensing range, and low energy consumption. It can sense human body signals on several sides, so that it can be effectively used in urinals, toilets and induction faucets.

[0027] As a preferred embodiment; a water flow cavity 8 is formed between the water inlet 6, the switch control device 4, the power generating device 2 and the water outlet 7; it can be understood that water enters through the water inlet 6, then flows to the switch control device 4, and if it is in the open state, it continues to flow to the power generating device 2, drives the impeller 10 of the power generating device 2 to rotate, thereby generating electrical energy, and finally the water can be discharged through the water outlet 7.

[0028] As a preferred embodiment; the power generation device 2 includes a generator 9 and an impeller 10, and a trough body is provided inside the mounting shell 1, and the generator 9 is installed inside the trough body, and the impeller 10 is connected to the shaft end of the generator 9, and the impeller 10 is located inside the water flow cavity 8; it can be understood that the trough body is mainly used to install the generator 9, and there is only one shaft output hole on the trough body, and the gap between the hole and the shaft is very small, smaller than the diameter of a water molecule, so water will not enter the trough body through the hole, and the system is an open water flow, after entering from the water inlet 6, it is finally discharged through the water outlet 7, and there is a water pressure direction in this process, which also prevents water from entering the trough body. In addition, the generator 9 adopts an epoxy resin encapsulation structure, which has a better waterproof effect.

[0029] As a preferred embodiment, the energy storage device 3 adopts a farad capacitor or a battery.

[0030] As a preferred embodiment; the induction water switch system also includes a power switch 11, which is fixedly installed in the installation shell 1 and close to one end of the water inlet 6, and the button end of the power switch 11 is exposed outside the installation shell 1; by providing the power switch 11, the purpose is to make the system power-off before installation, avoid static energy consumption of the induction control device 5 before installation, and then effectively protect the induction water system and extend the service life of the system; more specifically, during installation, the other installation surface is a plane, which is parallel to the bottom surface of the system, so the power switch 11 can be pressed down to power on, so that the system can be powered off before installation, and the energy storage device 3 will not be damaged. In addition, the power switch 11 of the utility model adopts a straight-insert four-corner touch switch produced by Shenzhen Huayuanxin Electronics Co., Ltd.

[0031] As a preferred embodiment, the power switch 11 is electrically connected to the energy storage device 3 ; the purpose is to press the power switch 11 to power on the energy storage device 3 after installation.

[0032] The working principle of the utility model is as follows: after sensing the human body signal, the induction control device 5 will control the opening of the pulse solenoid valve, so that water flows through the pulse solenoid valve and is discharged into the power generation device 2. The water flow impacts the impeller 10, causing the impeller 10 to rotate, thereby driving the generator 9 to rotate and generate electricity. The generated electric energy will be stored in the energy storage device 3, and the energy storage device 3 will supply power to the switch control device 4, and the remaining electric energy will be stored for static standby power consumption of the induction control device 5; in addition, the energy replenishment of this system is greater than the energy consumption (further explained by the circuit principle below), mainly because the switch control device 4 and the induction control device 5 require less electric energy, so that the energy storage device 3 is always in a fully charged state, and the power generation device 2 will not input electricity into the energy storage device 3 after it is fully charged.

[0033] like Figure 2 As shown, the circuit principle of the utility model is:

[0034] In order to avoid static energy consumption of the induction control device 5 before the product is installed, a power switch 11 is provided at the bottom of the product. After the product is installed, the power switch 11 is pressed down for a long time and is in a power-on state. When the induction control device 5 senses that a human body is moving within the detection range, it outputs a high level, which is amplified by the transistor 18 through the resistor 17 to energize the relay 19. At this time, the relay contact 20 is closed, and the power supply charges the pulse solenoid valve capacitor 21 through the closed relay contact 20. At the same time, the switch control device 4 receives a positive pulse to open the valve, and the water flows through the water inlet 6 to the generator 2, and the water pushes the leaves of the generator 2. The wheel 10 rotates, driving the generator 9 to work. The output voltage of the generator 9 is rectified by a bridge composed of four diodes (a first diode 12, a second diode 13, a third diode 14 and a fourth diode 15), stabilized by a three-terminal voltage regulator 22, filtered by a filter capacitor 16, and then charged to the energy storage device 3; when the human body leaves the range of the induction control device 5, the output is low level, the transistor 18 is cut off, the relay 19 is powered off, the relay contact 20 is reset, and the pulse solenoid valve capacitor 21 is reversely discharged to the switch control device 4 through the normally closed relay contact 20, the valve of the switch control device 4 is closed, and the water flow stops;

[0035] In addition, the output power of the generator 9 is 5V 120ma, which is about 0.6W; the static standby power consumption of the induction control device 5 is 3.7V 25ua, which is about 0.00001W; the instantaneous opening and closing power consumption of the switch control device 4 is 3.7V16ma 0.06W; the power consumption of the relay 19 when the switch control device 4 is turned on is 3.7V 20ma, which is about 0.08W; It can be seen from the above parameters that during each use, the energy supplemented by the generator 9 to the energy storage device 3 is far greater than the energy consumption of the switch control device 4 and the relay 19, and the remaining energy can supplement the daily standby energy consumption of the induction control device 5.

[0036] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
