Abstract
The utility model relates to a temperature-controlled color LED (Light Emitting Diode) shower nozzle. The temperature-controlled color LED shower nozzle internally comprises a temperature detecting circuit, an infrared distance measuring circuit, a singlechip, a color LED circuit and a power circuit, wherein the temperature detecting circuit and the infrared distance measuring circuit are used for acquiring the temperature of water and the distance form the shower nozzle to a human body; acquired signals are transmitted to the singlechip; the singlechip is used for processing the received signals and outputting the processed signals to the color LED circuit; the LED circuit drives an LED lamp to light; and the power circuit is used for supplying power to the singlechip. According to the temperature-controlled color LED shower nozzle, the color LED is controlled by the singlechip to emit light with different temperatures along with the varied temperature, and a light-sensitive distance detecting circuit is used for setting a threshold for the distance at the same time; and once the detected distance is above the threshold, the temperature can be correspondingly controlled. According to the temperature-controlled color LED shower nozzle, the functions are improved, and the color light which offers a large amount of fun to the life during showering can be provided.
Description
Technical field
The utility model relates to a kind of shower nozzle, particularly a kind of temperature control color LED shower nozzle.
Background technology
Present shower nozzle is a discharging device basically.But because the imperfection of water heater internal circuit or response control are not in place, so that temperature jump, the water temperature of sudden change causes human body sensory uncomfortable easily.
Summary of the invention
The utility model is the problem that the water temperature sudden change causes the human body discomfort during for bathing, a kind of temperature control color LED shower nozzle has been proposed, the color LED color changes thereupon when water temperature changes, and plays prompt facility, and temperature can be very not high when guaranteeing simultaneously close to shower nozzle is crossed from human body.
The technical solution of the utility model is: a kind of temperature control color LED shower nozzle, comprise shower nozzle, also comprise temperature sensing circuit, infrared distance measurement circuit, single-chip microcomputer, color LED circuit, power circuit in the shower nozzle, temperature sensing circuit and infrared distance measurement circuit collection water temperature and shower nozzle are to the distance of human body, collection signal send single-chip microcomputer, the single-chip microcomputer processing signals, output signal is bright to color LED circuit drives LED lamp, and power circuit is powered to single-chip microcomputer.
Described temperature sensing circuit adopts the DS18B20 temperature sensor.
Described infrared distance measurement circuit is comprised of TLN205 infrared transmitting tube, TPS708 infrared receiving tube and LM358 dual-stage amplifier, and light intensity finally is converted into 0-3V analog voltage.
Described color LED circuit forms array by 5 kinds of LED modules with different colors lamps, LED lamp band one current-limiting resistance of every group of series connection.
The beneficial effects of the utility model are: the utility model temperature control color LED shower nozzle, the Single-chip Controlling color LED sends the light of different temperatures along with different temperatures, light sensation is adjusted the distance apart from testing circuit threshold value is set simultaneously, when surpassing threshold value temperature is controlled accordingly.Temperature control color LED shower nozzle has not only been accomplished the improvement of function, and the light of colour is more lived and increased somewhat temperament and interest when having a bath.
Description of drawings
Fig. 1 is temperature control color LED control structure schematic block diagram in the utility model temperature control color LED shower nozzle;
Fig. 2 is temperature control color LED circuit diagram in the utility model temperature control color LED shower nozzle.
The specific embodiment
As shown in Figure 1, 2 temperature control color LED control structure schematic block diagram and circuit diagram in the temperature control color LED shower nozzle, the temperature sensor 18B20 in the temperature sensing circuit 1 measures in real time temperature value and is converted into data signal and passes to single-chip microcomputer 4.Infrared distance measurement circuit 2 real-time measuring distances, the infrared light of TLN205 infrared transmitting tube emission runs into the human body reflection, by infrared receiving tube TPS708 reception and the generation electric current corresponding with light intensity, electric current amplifies through the LM358 two-stage can obtain 0-3V aanalogvoltage, as the analog input amount of single-chip microcomputer 4 input ports, through analog-to-digital conversion it is become digital quantity.Through overtesting, with 20CM apart from the digital quantity of correspondence as threshold value, if distance less than 20CM, shower nozzle from human body too close to, the Single-chip Controlling heating module makes water temperature be no more than 50 degree.Single-chip microcomputer 4 output signals are to color LED circuit 5, light the led array of different colours in the different temperatures scope, and color LED circuit 5 forms array by 5 kinds of LED modules with different colors lamps, every group of LED lamp band one current-limiting resistance of connecting.Power circuit 3 employing transformers transfer 7.5V to by the 220V civil power and transfer the 5V power supply to by 7805 again.
