Description of reference numerals:
the device comprises a water tank 1, a first trigger point 11, a second trigger point 12, a third trigger point 13, a fourth trigger point 14, a water replenishing port 15, a water pressure sensor 2, a processor 21, a large-caliber electromagnetic valve 3 and a small-caliber electromagnetic valve 4.
Detailed Description
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without inventive labor, please refer to fig. 2 to 3.
The utility model provides an improved structure of water tank moisturizing device, includes water pressure sensor 2, heavy-calibre solenoid valve 3 and small-bore solenoid valve 4, 1 top in water tank is equipped with moisturizing mouth 15, heavy-calibre solenoid valve 3 and small-bore solenoid valve 4 are parallelly connected together, and connect moisturizing mouth 15 in order to control the switch of moisturizing mouth 15. The sizes of the calibers of the large-caliber electromagnetic valve 3 and the small-caliber electromagnetic valve 4 are in direct proportion to the water inflow rate.
The water pressure sensor 2 is positioned in the middle of the bottom of the water tank 1, the water pressure sensor 2 is provided with a processor 21, the processor 21 presets four trigger points, the four trigger points are measured by the water pressure sensor 2 according to the pressure of four different water levels, the position at the low water level is a first trigger point 11, the position above the low water level value and close to the low water level value is a second trigger point 12, the position below the high water level value and close to the high water level value is a third trigger point 13, and the position at the high water level value is a fourth trigger point 14;
