Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, technical solution of the present invention will be carried out below
Detailed description.Obviously, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Base
Embodiment in the present invention, those of ordinary skill in the art are obtained all without making creative work
Other embodiment belongs to the range that the present invention is protected.
As shown in Figure 1, the present invention provides a kind of air-conditioning system water flow switch, including target bar 1, the rotation of 1 one end of target bar
It is arranged on water flow switch, the other end is provided with target piece 11, and target piece 11 immerses in medium, further includes being arranged on target bar 1
Excitation unit 2；When air-conditioning system operation, excitation unit 2 generates the magnetic force that can control water flow switch closure after being powered, and works as sky
Excitation unit 2 is in off-position when adjusting system stops.Permanent magnet of the present invention by becoming target piece solves water flow into excitation body
Switch because in permanent magnet Long-Term Sorption water iron filings due to caused by magnetism weaken defect, not only raising water flow switch to working condition of water quality
Requirement, while also enhancing its resistance to magnetic and resistant to high temperatures ability, keep reliability higher.
As optional embodiment, target bar 1 is provided with attachment base 12 far from one end of target piece 11, and target bar 1 passes through connection

Body adds excitation body made of the silicon steel material of rust-proof coating using surface.
As shown in Fig. 2, excitation body is solenoid 22, solenoid 21 is fixed on attachment base 12, power supply unit and solenoid
The electrical connection of 21 both ends.Its magnetism, carrying magnetic when keeping it in work, when power-off are controlled by powering on to 21 both ends of solenoid
Not carrying magnetic, it is easy to adjust.
Magnetic field can be generated when solenoid 21 is loaded with electric current in the present invention, right-hand screw rule can be used to sentence for the direction in magnetic field
It is disconnected.The right hand is held into solenoid 21, then four fingers are stretched thumb along the central axis of solenoid 21 towards current direction
Directly, direction, that is, magnetic field pole N of thumb.
Magnetic induction intensity: B=(μ 0) nI (μ 0=4 π * 10^-7 is called the magnetic conductivity in vacuum)
There is the electromagnetic intensity of filling: B=(0 μ r of μ) nI (relative permeability that μ r is the packing material) in inside.Thus
It can be seen that the internal electromagnetic intensity with filler is bigger, further, excitation unit further includes magnetizer, magnetizer
Both ends are fixedly connected with attachment base 12 respectively, and solenoid 21 is spirally wound on magnetizer.
Preferably, magnetizer is silicon steel stick 22, is designed through the above structure, and the structural strength of excitation unit is not only increased,
Thermal adaptability is improved, higher reliability is also obtained.
