Detailed Description

The invention is further described below. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

The invention provides an intelligent spraying device based on pressure induction, which is shown in figure 2 and comprises a shower nozzle 5, a cold and hot water conveying mechanism, a card swiping device 4 and a pressure sensing device.

The cold and hot water conveying mechanism comprises a water heater 2, a hot water conveying pipeline 3, a cold water conveying pipeline 1, a water faucet 6, a 2/2 valve 7 and a valve spring 8, in the figure 2, 8-1 and 8-2 are two ends of the valve spring, the two ends are both opened and can be subjected to finish machining, one end 8-1 of the valve spring is connected with the 2/2 valve 7, and the other end 8-2 of the valve spring is connected with a pressure sensing device.

Furthermore, the valve spring needs to be mechanically strengthened, so that stress opposite to the working stress direction is generated in the spring material, and the service life of the spring is prolonged. Meanwhile, the pipeline material in the cold and hot water conveying mechanism preferentially uses a novel PP-R pipe, so that the valve spring is prevented from contacting water and being corroded to a certain extent.

The water heater 2 passes through the hot water pipeline 3 is connected 2/2 valve 7, cold water pipeline 1 is connected 2/2 valve 7, 2/2 valve 7 with tap 6 is connected the installation, through the manual rotatory tap regulation 2/2 valve aperture, the water yield of valve aperture control hot water and cold water and then the regulation temperature.

The pressure sensing device is connected to 2/2 valve 7 through the valve spring 8 to control the opening/closing state of 2/2 valve; when the 2/2 valve is in the open state, the cold and hot water is delivered to the shower nozzle through the pipeline after the water temperature is adjusted.

The card swiping device 4 consists of a card slot 4-1 and a gate valve 4-2, an RF identification module of an IC card is arranged in the card slot 4-1, the RF identification module is connected with the gate valve 4-2, the gate valve 4-2 is connected with the shower nozzle 5 through a pipeline, the RF identification module identifies whether the IC card is in the card slot 4-1, and the gate valve 4-2 controls the gate valve to be opened or closed through whether the IC card is in the card slot 4-1. When the 2/2 valve and the gate valve 4-2 are both in an open state, cold and hot water is conveyed to the shower nozzle through a pipeline after the water temperature is adjusted.

The pressure sensing device comprises a piezoresistor 13, a diaphragm 12, a pressure sensor piece 11 and a cavity 10, the cavity 10 is arranged between a pressure source 9 and the pressure sensor piece 11, the piezoresistor 13 is arranged below the pressure sensor piece 11, the piezoresistor 13 is adsorbed on the diaphragm 12, and the diaphragm 13 is connected with a valve spring 8 of the cold and hot water conveying mechanism; a gap is arranged between the pressure sensor sheet 11 and the piezoresistor 13.

The pressure source is transmitted to the pressure sensor piece through the cavity, so that the pressure sensor piece is in contact with the piezoresistor, the piezoresistor enables the diaphragm to stretch left and right along with mechanical deformation, and then the valve spring in the cold and hot water conveying mechanism is driven to deform, so that the 2/2 valve connected with the cold and hot water conveying mechanism is opened, and then the shower nozzle discharges water. When pressure sensor does not sense pressure, the piezoresistor adsorbed on the diaphragm is separated from the pressure sensor sheet, the diaphragm recovers deformation, the spring is stretched and reset, 2/2 valve opening recovers the original state, and the shower nozzle stops water.

Furthermore, a pattern prompt is arranged at the position of the pressure source to remind a user of standing when the user takes a shower, and the gravity of the user is used as the pressure source.

Further, when the card slot of the card swiping device identifies the IC card, the connection gate valve is switched to be in an open state, water adjusted by the 2/2 valve is conveyed to the shower nozzle, after the IC card is taken out from the card slot of the card swiping device, the gate valve is closed, the shower nozzle cannot supply water, and the intelligent spraying device stops working.

The working process of the invention is shown in figure 1 and comprises the following steps:

when showering, the IC card is placed in a card slot in the card swiping device, the RF identification module senses the IC card, and the gate valve is opened;

the user stands at the pattern prompt position, the gravity of the user is used as a pressure source and is transmitted to the pressure sensor piece through the cavity, the pressure sensor piece is in contact with the piezoresistor on the diaphragm, the piezoresistor generates mechanical deformation to stretch the diaphragm leftwards and rightwards, and further the valve spring connected with the piezoresistor is driven to generate deformation, the 2/2 valve is opened after the valve spring is compressed, and hot water generated by the water heater is mixed with cold water conveyed by the cold water conveying pipeline through the hot water conveying pipeline;

the valve 2/2 is adjusted by manually rotating the faucet, and the opening of the valve controls the water yield of the hot water and the cold water to be adjusted to a proper water temperature; is conveyed to the shower nozzle through a pipeline. After the water temperature is properly adjusted, the opening degree of the valve is unchanged, and the water temperature is basically kept unchanged.

After the user leaves, the pressure sensing device does not sense the pressure source, the piezoresistor adsorbed on the diaphragm is separated from the pressure sensor piece, the diaphragm restores to deform, the valve spring stretches to close the 2/2 valve, and the shower nozzle stops supplying water.

After the IC card is taken out from the clamping groove in the card swiping device, the RF identification module cannot sense the IC card, the gate valve is closed, the shower nozzle cannot supply water, and the intelligent spraying device stops working.
