The utility model relates to a water-heater water flow switch, which comprises a body provided with a fluid channel, a magnetic float arranged inside the fluid channel and a magnetic induction switch matched with the magnetic float. By adopting the structure, the magnetic float influenced by the water flow in the fluid channel ascends up and triggers the magnetic switch, by which the switch of an external circuit is controlled.
Description
[technical field]
The utility model relates to a kind of water heater water flow switch, particularly a kind of magnetic inductive water heater water flow switch.
[background technology]
In the passage of many liquid or gas transmission, need to use water flow switch usually.For example in water heater, just need to use ON/OFF and the sparking of water flow switch according to the on/off control coal gas of current.As shown in Figure 1, Fig. 1 is the cutaway view of prior art water heater water flow switch.In the water heater water flow switch 1 of prior art, inwall top in pipe joint 11 is rotatably connected to magnetic float 13,15 rotate and promote pole 17 around the shaft under the pressure effect of magnetic float 13 working fluid in pipe joint 11, connect the microswitch 19 of leading in the seal 18 by pole 17, and then realize the connection of circuit.The shortcoming of this water heater water flow switch is that sealing effectiveness is relatively poor, and liquid enters in the seal 18 along pole 17 easily, causes short circuit.
[utility model content]
For the water heater water flow switch that solves prior art is realized switch control mechanically, thereby liquid flows out the technical problem cause short circuit along mechanical part easily, and the utility model provides a kind of water heater water flow switch that utilizes magnetic induction part to realize contactor.
The utility model solves the water heater water flow switch of prior art and realizes switch control mechanically, thereby liquid along the technical scheme that mechanical part flows out the technical problem cause short circuit or leakage is easily: a kind of water heater water flow switch is provided, this water heater water flow switch comprises the main body that is provided with the fluid passage, be arranged in the fluid passage magnetic float and with the supporting magnetic induction switch of magnetic float.
According to the utility model one preferred embodiment, magnetic induction switch is arranged in the closed chamber on the outer wall of main body.
According to the utility model one preferred embodiment, the upper limit device is set in the fluid passage.
According to the utility model one preferred embodiment, the lower limit bit slice is set in the fluid passage, but lower limit bit slice longshore current body passage carries out position adjustments.
According to the utility model one preferred embodiment, magnetic float comprises seal and is arranged on the interior magnet of seal.
According to the utility model one preferred embodiment, described magnetic float moves at the flow action longshore current body pipeline of described fluid line, and the magnetic field intensity that makes the magnetic induction switch place is greater than predetermined threshold.
According to the utility model one preferred embodiment, main body and seal are non-magnetic permeability material.
According to the utility model one preferred embodiment, magnetic induction switch is a tongue tube.
According to the utility model one preferred embodiment, tongue tube is the open type tongue tube.
According to the utility model one preferred embodiment, magnetic induction switch is a Hall switch.
By adopting said structure, under the flow action in the fluid passage, magnetic float rises and triggers magnetic induction switch by magnet, controls the break-make of external circuit thus.Because magnetic induction switch and fluid passage isolate fully, and then short circuit and leakage problem in the prior art water heater water flow switch of avoiding, and simple in structure, low cost of manufacture, production in enormous quantities easily.

[specific embodiment]
Below in conjunction with drawings and Examples the utility model is elaborated.
As shown in Figure 2, Fig. 2 is the profile of the utility model water heater water flow switch one embodiment.In the present embodiment, water heater water flow switch 2 comprises the main body 21 that is provided with fluid passage 22, is arranged on the magnetic float 23 in the fluid passage 22, and this magnetic float 23 comprises seal 231 and is arranged on magnet 233 in the seal 231.Outer wall in main body 21 is provided with closed chamber 28, is provided with tongue tube 29 in the closed chamber 28.Have in fluid passage 22 under the effect of current, magnetic float 23 moves up, and flow velocity is during greater than certain threshold value, and magnetic float 23 rises to certain altitude, the magnetic field effect tongue tube 29 of the magnet 233 in the magnetic float 23.Tongue tube 29 adopts the open type tongue tube, and two ferromagnetism reeds are housed in the glass tube of tongue tube 29, and an end of this reed with certain interval toward each other.When magnet 233 during near tongue tube 29, two reeds magnetize respectively and the opposite polarity N utmost point and the S utmost point, thereby and thus mutually adhesive connect external circuit.Be filled with inert gas in the glass tube and be coated with inert metal, to prevent the reed activation at the place, contact.When the water in the fluid passage 22 did not flow, magnetic float 23 moved down under the effect of himself gravity.At this moment, the magnetic field of magnet 233 no longer acts on tongue tube 29, and the reed of tongue tube 29 is owing to the self-recovery original state and open circuit.In the present embodiment, the lower limit bit slice 25 that the internal thread 27 with main body 21 is complementary is set in the bottom of main body 21.This lower limit bit slice 25 can pass through internal thread 27, precession or back-out on main body 21.The effect of this lower limit bit slice 25 is: at first magnetic float 23 is put into fluid passage 22 during fabrication, then lower limit bit slice 25 is being screwed in main body 21, prevent that magnetic float 23 from skidding off, can regulate the elemental height of magnetic float 23 simultaneously according to the change in location of lower limit bit slice 25.In addition, also be provided with in main body 21 and prevent that magnetic float 23 from upwards shifting out the upper limit device of main body 21
As shown in Figure 3, Fig. 3 is the profile of the utility model water heater water flow switch one embodiment.Water heater water flow switch 3 shown in Figure 3 is with the difference of water heater water flow switch 2 shown in Figure 2: in the closed chamber 38 on main body 31 outer walls Hall switch 39 is set.For example, Hall switch 39 can comprise voltage-stablizer, Hall plate, difference amplifier, and this schmitt trigger and output stage are formed.Under the effect in the magnetic field of magnet 37, when magnetic induction intensity surpasses conduction threshold, Hall switch 39 conductings.
Each parts in the embodiment of above-mentioned fluid switch, for example the seal of main body, magnetic float and annular seal space that magnetic induction switch is set preferably adopt non-magnetic permeability material, avoid above-mentioned parts by magnet magnetization, and then avoid the influence to magnetic induction switch.
By adopting said structure, under the flow action in the fluid passage, magnetic float rises and triggers magnetic induction switch by magnet, controls the break-make of external circuit thus.Because magnetic induction switch and fluid passage isolate fully, and then short circuit and leakage problem in the prior art water heater water flow switch of avoiding, and simple in structure, low cost of manufacture, production in enormous quantities easily.
In the above-described embodiments, only the utility model has been carried out exemplary description, but those skilled in the art can design various embodiments according to different actual needs under the situation that does not break away from the scope and spirit that the utility model protects.
