When the light intensity is detected to reach the lower limit of the set threshold value, the photosensitive detection regulation and control module judges that the current time is rainy or nights, at the moment, the photosensitive detection regulation and control module controls the axial driving mechanism to eject the function regulating part 2 out of the condensation cavity 101, so that the opening of the condensation cavity 101 is opened, moisture in the air is continuously condensed on the wall of the condensation cavity 101 of the embedded type condensation cylinder 1 embedded in the lower part, rainwater flows into the condensation cavity 101, dew and rainwater in the condensation cavity 101 flow into the water storage cavity 102 which is communicated with the condensation cavity and has a larger area, all or part of water needed by sprinkling is provided through the collected rainwater and dew, and the purposes of saving water resources and using cost are achieved.
It should be noted that the water storage cavity 102 is additionally connected with a water pipe for supplying water to avoid the problem that the water spraying system cannot work normally due to insufficient water stored in the water storage cavity 102, and a water level detection sensor is installed in the water storage cavity 102, so that when the water level in the water storage cavity 102 is lower than a set value, water is sprayed in the external water source fragrance water storage cavity 102.
When liquid medicine needs to be sprayed, when the photosensitive detection regulation and control module judges that the current situation is a cloudy day or at night and the like with low illumination intensity, the photosensitive detection regulation and control module drives the function adjusting part 2 to act through the axial driving mechanism, so that the fixed water outlet 7 is disconnected from the conventional interface 4 and is in butt joint with the medicine spraying interface 5, then the water pumping device 8 and the liquid medicine injection mechanism 6 are controlled to start through the photosensitive detection regulation and control module, the spraying water in the water storage cavity 102 is pumped by the water pumping device 8 and is sprayed out through the fixed water outlet 7, the medicine spraying interface 5 and the spray head 3 in sequence, and the spraying water is mixed with the liquid medicine injected by the liquid medicine injection mechanism 6 under high pressure and is sprayed out through the spray head 3 in the process of flowing from the medicine spraying interface 5 to the spray head 3, so that the purpose of spraying the.
Through the function of spraying the liquid medicine for gardens sprinkling system adds, avoided the manual work to spray the liquid medicine and the intensity of labour that exists is big and there is the poisoning hidden danger scheduling problem, and detect and control through photosensitive detection regulation and control module and realize spraying the liquid medicine when illumination intensity is weak such as cloudy day, evening to ensure the best effect of giving medicine to poor free of charge.
It should be noted that, in order to avoid applying the medicine in rainy days, a rainfall sensor or a manual switch electrically connected with the photosensitive detection regulation and control module is arranged on or outside the multifunctional spray head assembly, so as to avoid the problem of low medicine application effect caused by applying the medicine in rainy days.
The axial driving mechanism comprises an electric push rod 9 with the bottom end installed on the wall of the condensation cavity 101, the top end of the electric push rod 9 is connected with the bottom end of the function adjusting part 2, an outer sealing pipe 10 with the bottom end fixedly installed on the inner wall of the condensation cavity 101 is sleeved outside the electric push rod 9, an inner sealing pipe 11 inserted in the outer sealing pipe 10 in a sliding mode is installed at the bottom end of the function adjusting part 2, the axial length of the inner sealing pipe 11 is not smaller than the maximum stroke of the function adjusting part 2, and the inner sealing pipe 11 is still inserted in the outer sealing pipe 10 when the function adjusting part 2 is ejected out of the condensation cavity 101.
The outer sealing pipe 10 acts on the condensation chamber 101 to prevent components such as the electric push rod 9 from contacting with water in the condensation chamber, and the inner sealing pipe 11 is matched with the outer sealing pipe 10 to guide the function adjusting part 2 to prevent the electric push rod 9 from obliquely swinging, so that the outer sealing pipe 10 is guaranteed to be isolated and sealed from the condensation chamber 101 when the function adjusting part 2 is jacked up.
What is further optimized on the above embodiment is that the spray head 3, the conventional interface 4 and the spraying interface 5 are sequentially arranged towards the direction of the electric push rod 9, the spray head 3 positioned at the top end improves the spraying range, and the spraying interface 5 positioned below the conventional interface 4 sinks into the condensation cavity 101 when the conventional interface 4 is in butt joint with the fixed water outlet 7, so that the problem of entering sundries in the spraying interface 5 is avoided.
And, the conventional interface 4 and one end of the spraying interface 5 are connected through a common channel 12, one-way check valves 13 are installed in the spraying interface 5 and the common channel 12 located in the conventional interface 4 and the spraying interface 5, and the problem that the spraying water sprayed by the conventional interface 4 is discharged through the spraying interface 5 is avoided through the arranged one-way check valves 13.
The inlet mechanism 6 comprises a plurality of branch channels 601 and a main channel 602 communicated with the branch channels 601, one end of the main channel 602 relative to the branch channels 601 penetrates through the top end of the function adjusting part 2, a concentrated liquid medicine pot 603 communicated with the main channel 602 is installed at the top end of the function adjusting part 2, one end of the branch channel 601 relative to the main channel 602 is communicated with the common channel 12, the joint of the branch channel 601 and the common channel 12 is located at one end, facing the medicine spraying port 5, of the one-way check valve 13 in the common channel 12, and the branch channel 601 is provided with a pressure release valve 14.
