Abstract
The utility model relates to a vertical type water flow magnetic control switch, which is provided with a shell, wherein the shell is provided with a water inlet and a water outlet. The vertical type water flow magnetic control switch is characterized in that a magnetic control switch assembly is arranged at the water inlet; the magnetic control switch assembly comprises a fixed seat and a magnetic receiver, wherein the fixed seat is fixed on the shell in a sealing way; the section of the magnetic receiver presents in a P shape; the P-shaped extending end of the magnetic receiver is movably connected to the fixed seat; a magnet is arranged in the P-shaped cavity of the magnetic receiver, and is hung above the water inlet; the fixed seat is also provided with a reed switch seat in which a reed switch is arranged; and when the magnetic receiver is overturned upwards under the action of being impacted by the water flow from the water inlet, the magnet approaches the reed switch. By adopting the structure, the utility model can control the magnetic control switch by utilizing that the water flow acts on the magnetic receiver and the magnetic receiver can restore under self weight, and has the advantages of accurate work and safer and more reliable use.
Description
Technical field
The utility model relates to the starting switch in the water heater, relates in particular to a kind of vertical current magnetic switch.
Background technology
Existing magnetic switch has two kinds usually, a kind of horizontal as shown in Figure 1 current magnetic switch, its operation principle is: when water inlet 6 water inlets, the magnet 3 that current will be equipped with magnetic core pushes away toward housing 1 right side, the seal cover of housing 1 right-hand member is provided with the magnetic control element steel spring pipe 9 of magnetic switch, when magnet 3 during near right-hand member, two elastic metallic reeds adhesive of steel spring pipe 9, signal output, the magnetic switch action is when current stop, the fixing magnet 5 of housing 1 left end sucks back magnet 3, the metal spring leaf of steel spring pipe 9 disconnects, signal interruption, and magnetic switch disconnects.Though this structure is simple, adopts matched in clearance between magnet and the valve pocket, under flow action, has viscous force, or, its activity is obstructed owing to contain impurity in the water quality and, be adsorbed on the magnet easily by magnetisable material and attached particle, can't operate as normal; Another kind of vertical current magnetic switch shown in Figure 2, its complex structure, magnetic control element steel spring pipe 9 is fixed on the sidewall of housing 1, under flow action, move up and down the adhesive of two elastic metallic reeds and the disconnection of control steel spring pipe 9 by magnetic core float 3, thereby control magnetic switch action, its major defect is, magnetic core float 3 is when return, owing to lean on closer with the steel spring pipe, magnetic is still disturbed the steel spring pipe, may cause steel spring pipe output error signal, perhaps has impurity on magnetic core float 3, product some when oblique, magnetic core float 3 is can the generation work undesired.Be stuck in the pipeline of switch, return does not cause dry-reed tube switch not disconnect, and causes the water heater dry combustion method easily.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, the vertical current magnetic switch that can accurately work.
For realizing above purpose, the utility model adopts following technology: magnetic switch is provided with housing, housing is provided with water inlet, delivery port, wherein be provided with the magnetic switch assembly in the water inlet, the magnetic switch assembly comprises holder and magnetic receiver, the holder sealing and fixing is on housing, the magnetic receiver cross section is P shape, magnetic receiver P shape elongated end is movably connected on the holder, and magnetic receiver P shape cavity is built-in with magnet, is suspended at the water inlet top, also be provided with the tongue tube seat on the holder, the built-in tongue tube of tongue tube seat, when magnetic receiver was upwards overturn by the water inlet water impact, magnet was near tongue tube.
Above-mentioned magnet is the ferrite alnico magnets.
Above-mentioned magnetic receiver P shape elongated end and holder junction are provided with postive stop baffle.
Above-mentioned magnetic receiver P shape elongated end is connected by stainless steel shaft with holder.
Above-mentioned magnetic receiver P shape top is provided with angled protrusions.
The utility model adopts above structure, and when water inlet was intake, current impacted upwards upset with magnetic receiver, can make two elastic metallic reeds of tongue tube be subjected to the magneticaction adhesive, signal output, magnetic switch action; When the water inlet current stopped, water refluxed because of deadweight produces in the housing, acts on the magnetic receiver, makes the timely return of magnetic receiver, and magnetic receiver also can return because of deadweight when losing impact of water simultaneously, and the metal spring leaf of steel spring pipe disconnects, and signal is ended, and magnetic switch disconnects.Therefore this is simple in structure, and work is accurately used safety and reliability.
