Description
Technical field:
The utility model relates to a kind of water flow switch, particularly a kind of magnetic strength water flow switch that is used for instant-heating electric water heater.
Background technology:
The water flow switch of electric heater in the market has multiple, commonly used a kind ofly cut off the water supply or water flowing can realize outage or switches on for hydraulic pressure switch.Described hydraulic pressure switch is provided with the stainless steel substrates of tool male and fomale(M﹠F), and described stainless steel substrates is realized the water flowing energising, cut the supply of water and electricity under the pressure of water.It is consistent that the elastic force of this kind hydraulic pressure switch structural requirement stainless steel substrates is wanted, percent defective height during making, and complex structure, and also stainless steel substrates is thinner, easily leaks after the welding, the cost height.Simultaneously, this kind structure only is used for the electric heater (internal pressure is 0MPa) of open type, is not useable for closed electrical water heater (internal pressure is 0.6MPa) and uses, be connected into the closed electrical water heater use in case refute, continue heating, dry combustion method easily takes place, the water heater life-span is short.
Inductance type, high frequency oscillation formula and reed switch relay that other three kinds of water flow switches adopt bar magnet to expose in water are realized, this kind structure is come control relay by the signal code that magnetic induction produced by electronic circuit by coiling, to realize water flowing energising, the operation principle of cutting the supply of water and electricity and heating.The line footpath of the enamel-covered wire of described coil is thinner, generally at 0.03mm-0.08mm, and the technique for coiling complexity, pigtail splice is easily broken, and coil is easy burn-out when long-term energising, and maintenance rate is higher.The water out adapter of the water flow switch of reed switch relay, the normal screw thread that adopts adds the glue connection, easily leak, the adhesive of tongue tube requires the magnetic of magnet bigger, and magnet holds tongue tube and can not fall down sometimes after cutting off the water supply, and causes dry combustion method, magnet exposes easily to get rusty to take off in water and splits, the right-angle side at two ends is easy to hang to be caused to cut off the water supply on the inwall of water service pipe and not to cut off the power supply, and tongue tube connects high voltage source on the relay when water nozzle leaks, can related generation leaky.This shows, be necessary to provide a kind of being easier to produce the electric heater water flow switch that security performance is high.
The utility model content:
The utility model in existing deficiency aspect the control, and provides a kind of security performance height, highly sensitive at above-mentioned existing instant electric water heater's water flow switch, and water flow switch simple in structure.
In order to achieve the above object, the technical solution adopted in the utility model:
The magnetic strength water flow switch, this switch is made up of the magnetic strength device of water flowing cavity and setting on it, described magnetic strength device is by Hall element and can forming with the rotor of current generation rule magnetic flux change, and described rotor fixed in position is at the middle part of water flowing cavity, and can rotate with current; The magnetic flux change that the side that this Hall element is placed in the water flowing cavity produces with current with the perception rotor, and produce the corresponding signal of telecommunication and be transferred to external microprocessor and handle.
The described epitrochanterian number of blade is an even number, and this blade is and is symmetrically set, and is mounted with on all four magnet on the correspondence position of every blade end, and magnet is pressed the N/S alternating polarity and arranged.
Described Hall element adopts the element of miniature patch shape, is fixed in by side plate on the side of water flowing cavity.
In order to improve the sensitivity of Hall element, the coverage between the Hall element of rotor center and water flow switch biasing is 5mm.
The both-end channelling water is adopted in the water flowing chamber of described magnetic strength water flow switch.
The utility model that obtains according to technique scheme adopts rotor exterior to add magnetic pole, reduced the coverage of Hall element and checker magnetic flux greatly, the validity and the precision of Hall element response have been improved, make electronic component change the caused magnetic induction intensity of the pulse signal of flow, the precision of variable quantity and the sensitivity of variation increase thus; The architectural characteristic that adopts paster micro element and side to put plate has strengthened the reliability of circuit; Structure is small and exquisite, and the total appearance and size of whole water flow switch parts all has only 80mm*40mm*25mm, but and both-end water flowing application convenience.
Description of drawings:
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is the utility model structural representation.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
The utility model is in order to solve the existing problem of above-mentioned existing instant-heating electric water heater water flow switch, and a solution is provided, and as shown in Figure 1, is a kind of magnetic strength water flow switch, and this switch comprises two parts: water flowing cavity and magnetic strength device.
In order to rotate the well-regulated magnetic flux change that produces with current, control instant electric water heater's switch, at Hall element 10 of side biasing of water flowing cavity 1 by rotor.The left side of water flowing cavity 1 is provided with the resettlement groove 11 of a Hall element 10, and the both sides of this resettlement groove 11 are provided with fixed leg 12 and are used to block Hall element 10 and fixed side 14.Adopt the Hall element 10 of miniature patch shape in the utility model, its both sides have the bayonet socket 13 that matches with fixed leg 12, during arrangement element snapped in resettlement groove 11, fixing by side plate 14, element carries out the transmission of signal with the outside microprocessor of making usefulness that starts to control simultaneously, so effectively the reliability of intensifier circuit.
In order to improve the sensitivity of Hall element, the coverage between the Hall element of rotor center and water flow switch biasing is 5mm simultaneously.
The magnetic strength water flow switch that obtains according to technique scheme, when operation, when current flow through the water flowing cavity, because the active force of current can drive the cavity internal rotor and rotate, thereby the rule rotation that 6 small magnets that N/S alternating polarity symmetrical fully on the rotor is arranged have occurs, the variation of this well-regulated magnetic flux makes the Hall element that is contained in the cavity side produce well-regulated opening and cut-off signal, be the high-low level conversion, Hall element is transferred to these signals of telecommunication microprocessor again and detects the open and close of handling and being controlled electric heater.
