Abstract

The utility model relates to a fountain capable of being automatically turned on and off by using a microwave human body sensing switch. The fountain is characterized in that the fountain comprises a water pump, a spray pipe, a relay, and a microwave human body sensing switch module and a single-chip microcomputer module which are arranged in an equipment box, the microwave human body sensing switch module is connected with the single-chip microcomputer module, the single-chip microcomputer module is connected with the relay and the relay is connected with the water pump. During working, when the microwave human body sensing switch module senses that people exist in a public place, a signal is transmitted to the single-chip microcomputer module, the single-chip microcomputer module controls the relay, the relay changes the working state of a control circuit and the fountain is turned on; when no people exist, the microwave human body sensing switch module transmits a signal to the single-chip microcomputer, the single-chip microcomputer controls the relay, the relay changes the working state of the control circuit and the fountain is turned off. The fountain capable of being automatically turned on and off by using the microwave human body sensing switch has the beneficial effects that since the microwave human body sensing switch mainly adopts a Doppler effect principle, when people do activities within a sensing range, the switch is always turned on and is not turned off until the people leave and the trouble in manually turning on and off the fountain is avoided.

Description

A kind of fountain that utilizes microwave human induction switch to open and close automatically

Technical field

The utility model relates to a kind of fountain, particularly a kind of fountain that utilizes microwave human induction switch auto-breaking.

Background technology

Summer public place fountain view, square with fountain is especially welcomed by the people, generally park, square has been opened more than the people that the strategy of fountain is gathering and has just been opened fountain, people has lacked and has just closed fountain, one is heading straight for fountain can waste electric energy, but comes less opening and closing fountain also in manual operation state according to the many people of people.

Summary of the invention

The purpose of this utility model is exactly to solve the problem of mentioning in above-mentioned background technology, and a kind of fountain that utilizes microwave human induction switch to open and close automatically is provided.

The technical solution adopted in the utility model is: a kind of fountain that utilizes microwave human induction switch to open and close automatically, it is characterized in that: comprise water pump, jet pipe, relay, also comprise the microwave human induction switch module and the one-chip computer module that are arranged in appliance case, described microwave human induction switch module is connected with one-chip computer module, described one-chip computer module is connected with relay, and described relay is connected with water pump.During work, when microwave human induction switch module detects public place and has people, transmit a signal to one-chip computer module, one-chip computer module control relay, relay changes control circuit duty, fountain is opened, when nobody is, microwave human induction switch sends a signal to single-chip microcomputer, one-chip computer module control relay, relay changes control circuit duty, fountain power-off.

The beneficial effects of the utility model are: microwave human induction switch, mainly utilize Doppler effect principle, and movable at induction range as people, switch is connected all the time, until people leaves and just automatically closes afterwards, removes the trouble that people is opening and closing fountain from.

Accompanying drawing explanation

Below in conjunction with accompanying drawing and example, the utility model is described in further detail.

Fig. 1 is the simplified figure of structure of the present utility model.

In figure: 1, microwave human induction switch module, 2, one-chip computer module, 3, relay, 4, water pump, 5, jet pipe, 6, appliance case.

The specific embodiment

As figure, a kind of fountain that utilizes microwave human induction switch to open and close automatically, it is characterized in that: comprise water pump 4, jet pipe 5, relay 3, also comprise the microwave human induction switch module 1 and the one-chip computer module 2 that are arranged in appliance case 6, described microwave human induction switch module 1 is connected with one-chip computer module 2, described one-chip computer module 2 is connected with relay 3, and described relay 3 is connected with water pump 4.During work, when microwave human induction switch module detects public place and has people, transmit a signal to one-chip computer module, one-chip computer module control relay, relay changes control circuit duty, fountain is opened, when nobody is, microwave human induction switch sends a signal to single-chip microcomputer, one-chip computer module control relay, relay changes control circuit duty, fountain power-off.

Claims
