Background technology
With the progress of social life, the quality of life more and more higher of people, support at home potted flower can cultivate one's taste, rich
Rich life.Meanwhile, planting plants can pass through photosynthesis absorbing carbon dioxide indoors, purify the air of a room, having flowers and trees
Local in the air anion build up more, so air is also especially pure and fresh, and flowers and trees can be with harmful in absorption air
Gas, therefore, cultivation tray is planted and is liked by increasing people indoors.
And whether potted plant irrigation amount can accomplish timely and appropriate discovery, it is to grow flower the key of success or failure.But, in life, people are total
When being to have to have no time to attend to, such as work too busy or go on business, travel.Flowers and plants growth question more than 80% is by watering
Problem causes；The flowers and plants of not at all easy plantation some months, because watering not in time, growing way is bad, for beautifying the flowers and plants at home
Almost become sky to set, if do not planted, in family, there is no green, lacking life, if retained, and flowers and plants have growed not vigorous and also can
Impact indoor decorative effect.
Although current potted plant automatic sprinkler on sale on the market, price is sufficiently expensive, and mostly can only set one
The individual regular watering time, it is difficult to accomplish water to potted plant timely and appropriate discovery.Also there is more economical potted plant boiler alarm, can remind
People give pot water in time, but this alarm can only be reported to the police, and watering needs for people and take action on one's own.When family is unmanned
When, even if reporting to the police, also nobody waters, just do not have due effect.
Content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, provides automation flower-watering device, and it can be according to potted plant wet
The difference of degree is automatically obtained startup and the stopping of function of watering, without manual operation, easily and effectively.
The present invention solves the above problems by the following technical programs：
Automation flower-watering device, including humidity sensor, shower nozzle, magnetic valve, water receiver, relay and control device, described storage
Be connected with water pipe between hydrophone and shower nozzle, described magnetic valve is arranged on the pipeline of water pipe, the input of described control device and
Output end is connected with the output end of humidity sensor and the input of relay respectively, the output end of relay and magnetic valve phase
Even；Described control device includes signal adapter, comparator and the driver being sequentially connected, and described signal adapter is passed with humidity
The output end of sensor is connected, and driver is connected with the input of relay；Described comparator includes operational amplifier, operation amplifier
The in-phase input end of device has been sequentially connected in series second resistance and reference voltage source, and the inverting input of operational amplifier is in series with first
Resistance, the output end of operational amplifier is in series with 3rd resistor；Described comparator is additionally provided with voltage-stablizer, and the one of described voltage-stablizer
End ground connection, the other end is connected relative to the other end of concatenation operation amplifier out with 3rd resistor.The present invention utilizes humidity to pass
Sensor detect flowerpot in soil humidity and by process after signal send control device to, when soil moisture does not reach preset value
When, control device drives relay closure, so that magnetic valve is opened, makes water receiver pass through water pipe and shower nozzle and carries out certainly to potted plant
Dynamic pouring；Conversely, when soil moisture exceedes preset value, relay is opened in the presence of control device, so that magnetic valve
Close, stop pouring.Whole process without manual operation, easily and effectively
Further, described voltage-stablizer is made up of the Zener diode of two anti-phase series connection.Voltage stabilizing two pole using differential concatenation
Pipe can play two-way overvoltage protection effect to circuit, when circuit overvoltage, diode puncture short first.Further, institute
State and between the signal adapter of control device and comparator, be additionally provided with amplifier.Due to, after soil moisture changes, believing
Number magnitude of voltage produced by converter is less, thus the present invention is amplified to magnitude of voltage by arranging an amplifier, carries
High accuracy.
Further, described humidity sensor is Relative Humidity Sensor.The present invention adopts HS1101 relatively wet
Degree sensor, design cost is low, and structure is simple, workable.
The beneficial effects of the present invention is：The startup of function of watering can be automatically obtained according to the difference of potted plant humidity and stop
Only, without manual operation, easily and effectively；Secondly, improve the signal accuracy of whole device, reliability by arranging amplifier
Good；Finally, this device design cost is low, and structure is simple, workable.
