The O-ring 11 is arranged between the flow meter assembly upper hoop 6 and the waterway fixing seat 1 to achieve a sealing function, thereby preventing liquid from overflowing through the gap between the flow meter assembly upper hoop 6 and the waterway fixing seat 1 and affecting the metering accuracy.

[0028] An annular protrusion is provided on the upper part of the flow meter assembly upper hoop 6, and the annular protrusion is arranged at the top of the waterway fixing seat 1. The spiral sleeve 7 is threadedly sleeved on the waterway fixing seat 1, and the annular protrusion is arranged between the waterway fixing seat 1 and the spiral sleeve 7, so as to facilitate the combination of the flow meter assembly upper hoop 6 and the waterway fixing seat 1 through the spiral sleeve 7.

[0029] A slot is provided at the top of the upper hoop 6 of the flow meter assembly, and a clamp 10 is clamped on the slot. The clamp 10 is arranged at the top of the spiral sleeve 7. The design of the clamp 10 facilitates the limiting of the spiral sleeve 7, thereby assembling and fixing the upper hoop 6 of the flow meter assembly and the waterway fixing seat 1 together.

[0030] A water inlet 14 is provided on the left side of the water channel fixing seat 1, a water outlet 13 is provided on the right side, and an arrow mark indicating the direction of water flow is provided on the front side of the water channel fixing seat 1.

[0032] The induction coil 8 is a Hall sensor.

[0033] During use of the utility model, the impeller 5 is rotatably connected to the impeller fixing ring 4, and the impeller 5 and the impeller fixing ring 4 are matched and placed between the flow meter assembly upper hoop 6 and the flow meter assembly lower hoop 3, and then the flow meter assembly lower hoop 3 and the flow meter assembly upper hoop 6 are fixed together by the upper and lower fixing screws 2, and then the flow meter assembly upper hoop 6 and the flow meter assembly lower hoop 3 are placed on the waterway fixing seat 1 through the opening at the upper end of the waterway fixing seat 1, and are limited and fixed by the spiral sleeve 7, and then the circuit board 9 and the induction coil 8 are fixed in the circuit plug assembly 12, and electrically connected through the wire, and then the circuit plug assembly 12 is fixed on the flow meter assembly upper hoop 6, and the induction coil 8 is set on the upper side of the impeller 5.

The impeller 5 is made of magnetic material. When the impeller 5 rotates one circle, the induction coil 8 receives the signal and passes it into the circuit board 9. The circuit board 9 converts the signal into data and sends it to the controller. The actual flow rate is determined by the number of revolutions of the impeller 5, thereby accurately controlling the output of the water pump to ensure that the per mu usage set by the user is consistent with the actual amount.

[0035] The material of impeller 5 itself is magnetic, and each magnet has the same polarity. Due to the properties of the magnetic field distribution of the magnet, the magnetism is strongest at the midpoint position and weakened at the offset position. When impeller 5 rotates in a fixed manner, the Hall sensitive elements opposite to impeller 5 receive different magnetic signals, thereby outputting different signal waveforms. The signal shaping circuit filters out useless signals and only keeps the positive signal. The signal amplification circuit further processes the positive signal to output a qualified and stable waveform signal. The Hall sensitive element is located directly above the impeller 5 magnet and receives the strongest signal.

[0036] The above are only embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included within the scope of the claims of the present application.
