Description
Technical field:
The utility model relates to the Electromagnetic water pump technical field, refers in particular to a kind of Electromagnetic water pump of can regulate output flow.
Background technique:
At present, small-sized plunger type Electromagnetic water pump has obtained using widely in every field, and particularly miniature plunger type water pump has obtained extensive use with the small and exquisite precision of its structure, and it can be applied in products such as coffee machine, steam generating device.The principle of plunger type Electromagnetic water pump is: plunger is not to utilize bent axle or applied external force, and plunger is a action of a magnetic field lower stress externally, carries out reciprocal operation.Wherein the external magnetic field is half-wave operation, and electromagnetic field only applies the power of compression direction (forward operation) to plunger, and the stressed spring that comes from water pump inside during plunger return (inverted running).Under the effect of electromagnetic force and spring force, plunger back and forth moves, and water is sucked by water intake, is pumped by water outlet.
The flow of its pump water of present electromagnetic pump remains unchanged, if change the flow of pump, can only change the size of pump, the operation stroke of plunger and the frequency of okperation of plunger usually.Wherein change the size of pump, the operation stroke of plunger all can relate to the change of pump body, this change bothers very much, and this change can't adjust, and can't adjust the flow of pump as required at any time.
In addition, the pump water flow of Electromagnetic water pump unit time be with its frequency of okperation be closely-related.The frequency of present civil power is 50Hz, that is to say, present Electromagnetic water pump frequency of okperation is per second 50 times, and promptly the plunger per second will be accomplished 50 times pump water operation.If the pump water flow that the frequency of okperation of adjustment plunger just can be regulated Electromagnetic water pump.
The model utility content:
The utility model technical problem to be solved is to provide a kind of Electromagnetic water pump of can regulate output flow, is applied to the demand of different use occasions, thereby the utility model is to change the plunger frequency of okperation through changing power frequency, adjusts its pump water flow.
In order to solve the problems of the technologies described above; The utility model has adopted following technical proposals: this Electromagnetic water pump comprises: the pump housing, the magnetic core plunger that is installed in the outside electromagnetic coil module of the pump housing and is installed in pump housing inside; This Electromagnetic water pump also has a circuit board, and this circuit board is provided with the electric current frequency-variable controller, and the coil of said electromagnetic coil module is connected with frequency-variable controller; Foreign current inputs to circuit board through the input end of Electromagnetic water pump, through exporting coil behind the frequency-variable controller to.
Furthermore, in the technique scheme, described circuit board is provided with eliminator, and the sine wave that will import through eliminator is adjusted into half-wave.
Furthermore, in the technique scheme, described frequency-variable controller is adjusted into 0-25/30Hz with the power frequency of input by 50/60Hz.
Furthermore, in the technique scheme, be provided with the Returnning spring that acts on the plunger in the described pump housing, back and forth move through the magnetic force of electromagnetic coil module generation and the elastic force driven magnetic stem stem plug of Returnning spring.
The utility model increases a frequency-variable controller on circuit board; So-called frequency-variable controller is exactly can the frequency of input current be regulated; Change the frequency of electric current, so just can change the frequency of okperation of plunger, thus the pump water yield of Electromagnetic water pump in unit of adjustment's time.Existing Electromagnetic water pump is the flow that can't change water pump; It will keep the frequency of 50Hz always; Flow is in a constant state (decay that certainly causes because of self operating life except pump) basically; And the utility model can be adjusted the flow of Electromagnetic water pump as required at any time, so that the flow of pump better matches with working environment, state, reaches better using effect.
In addition, can accurately regulate and control the flow of water pump, and help delaying that temperature raises fast under the water pump high frequency state, help to increase the working life of product through changing power frequency.

Embodiment:
Below in conjunction with specific embodiment and accompanying drawing the utility model is further specified.
See shown in Figure 1ly, what present embodiment adopted is a kind of half-wave Electromagnetic water pump, and it comprises: the pump housing 1, electromagnetic coil module 2, plunger 3 and Returnning spring 4.Wherein, Electromagnetic coil module 2 is installed in the pump housing 1 outside; The plunger 3 that adopts magnetic core to make is installed in the pump housing 1 internal cavity; Returnning spring 4 is arranged in the pump housing 1, and Returnning spring 4 acts on the plunger 3, and it is in the opposite direction that Returnning spring 4 acts on the electromagnetic force that elastic force direction and electromagnetic coil module 2 on the plunger 3 act on the plunger 3.
See shown in Figure 2ly, this Electromagnetic water pump also has a circuit board 5, and this circuit board 5 can integrate design with the pump housing 1, also can adopt lead to pass through outside the access.This circuit board 5 is provided with the electric current frequency-variable controller, and the coil of said electromagnetic coil module 2 is connected with frequency-variable controller, and foreign current inputs to circuit board 5 through the input end 11 of Electromagnetic water pump, through exporting coil behind the frequency-variable controller to.
Described circuit board 5 is provided with eliminator (realizing filtering through diode), and the sine wave that will import through eliminator is adjusted into half-wave.
During work, see shown in Figure 3ly, the external power supply of input end 11 input is that frequency is the electric current of 50Hz, and this electric current inputs to circuit board 5, through 2 power supplies of the electromagnetic coil module in 5 pairs of water pumps of circuit board.Because circuit board 5 is provided with eliminator, through behind the eliminator, sinusoidal ac becomes half-wave current.When electromagnetic coil module 2 generation half-wave frequency conversion magnetic fields, i.e. the magnetic force of electromagnetic coil module 2 generations is the magnetic force in the same way of interval interrupt.This magnetic force will promote as the right operation of plunger 3 to the left-hand of magnetic core.When the magnetic force of electromagnetic coil module 2 interrupts, plunger 3 will reset rapidly under Returnning spring 4 effects (promptly to the operation of a dextrad left side), so constantly back and forth carry out the piston operation, and the water intake of water by the pump housing 1 pumped into, and pumped by water outlet.
See shown in Figure 4 since circuit board 5 in be provided with regulating switch 6, can input to the power frequency in the electromagnetic coil module 2 by regulating circuit plate 5 through regulating this regulating switch 6.For example, circuit board 5 is adjusted into 25Hz with the power frequency of input by 50Hz, and the piston operation frequency of plunger 3 will become original half thely this moment, and the speed of pump water descends like this, and the pump water yield of water pump is just decline also.Usually, described frequency-variable controller is adjusted into 0-25Hz with the power frequency of input by 50Hz.Through adjusting to frequency-variable controller, regulate the input flow rate of water pump accurately, simultaneously, and the downward modulation power frequency, the temperature that can delay the electromagnetic coil module raises fast, increases the working life of product.
