Preferably, the opening of the housing 2 is provided with a flange 201, and the end cover 601 is attached to the flange 201 and fixedly mounted on the flange 201. The coil 501 is disposed in the mounting cavity 205, a mounting bracket is disposed in the mounting cavity 205, and the coil 501 is fixed on the mounting bracket.

The principle of the invention for feeding and discharging washing liquid is as follows:

the rotor 4 vibrates reciprocally in the sleeve cavity 203 to drive the washing liquid in the sleeve cavity 203 to fluctuate, the washing liquid fluctuation has a certain amplitude, the washing liquid in the sleeve cavity 203 can obtain the amplitude along the axial direction of the sleeve cavity 203, the washing liquid moves along the axial direction of the sleeve cavity 203, and the washing liquid is discharged out of the sleeve cavity 203 through the liquid discharge pipe 204, so that the liquid discharge of the washing liquid is realized;

as shown in fig. 1, the liquid discharge pipe 204 and the liquid suction pipe 603 are both internally provided with a one-way conduction structure, through which washing liquid enters the sleeve cavity 203 in one direction through the liquid suction pipe 603, and washing liquid in the sleeve cavity 203 is discharged in one direction through the liquid discharge pipe 204, and the one-way conduction structure comprises a one-way valve 206, a membrane with one-way conduction function, a valve and the like, so that the structure is simple, and the conduction effect is good. Of course, other control means may be provided in the liquid pipe in order to switch on/off the liquid suction pipe 603 and the liquid discharge pipe 204, for example: control valves, other check valves, etc.

In order to save the cost, as shown in fig. 4 and 5, only the liquid suction pipe 603 or the liquid discharge pipe 204 may be provided with a one-way conduction structure, and the use purpose of guiding the washing liquid and the like from the liquid suction pipe into the sleeve cavity 203 and driving the liquid discharge pipe 204 by the reciprocating vibration of the receiver 4 may be achieved.

Since the washing liquid can only enter the sleeve cavity 203 in one direction by the liquid suction pipe 603 and is discharged out of the sleeve cavity 203 in one direction by the liquid discharge pipe 204, under the continuous vibration of the rotor 4, the fluctuating washing liquid is continuously discharged out of the sleeve cavity 203 by the liquid discharge pipe 204, and the washing liquid in the sleeve cavity 203 is pulled to continuously move towards the liquid discharge pipe 204 due to certain viscosity of the washing liquid, and the washing liquid in the liquid suction pipe 603 is pulled to continuously enter the sleeve cavity 203 in the process of moving towards the liquid discharge pipe 204, so that circulation is formed, the washing liquid continuously enters the sleeve cavity 203, and the washing liquid continuously exits the sleeve cavity 203, and thus the liquid inlet and the liquid outlet of the washing liquid are realized.

Preferably, the washing liquid can enter the sleeve cavity 203 through the liquid suction pipe 603 by means of self gravity, so that the washing liquid entering the sleeve cavity 203 has certain pressure, the pressure is controlled to be insufficient to open the one-way valve 206 in the liquid discharge pipe 204, the washing liquid is driven to fluctuate by means of vibration of the rotor 4, and the one-way valve 206 in the liquid discharge pipe 204 is opened under the combined action of fluctuation and pressure of the washing liquid, so that the liquid discharge of the washing liquid is realized.

For the pressure of the washing liquid in the sleeve cavity 203, the pressurizing device can be further arranged to control the washing liquid in the sleeve cavity 203 to have proper pressure, and the pressure applied to the washing liquid in the sleeve cavity 203 can be reduced by applying the pressure to the washing liquid in the sleeve cavity 203, so that on one hand, the difficulty in opening the one-way valve 206 through vibration of the mover 4 is reduced, the mover 4 does not need to vibrate with larger amplitude to improve the pressure of the liquid fluctuation, the one-way valve 206 can be opened under the condition of smaller amplitude vibration, electric energy is saved, and cost is saved, on the other hand, the mover 4 can vibrate with high frequency to drive the washing liquid to vibrate, the one-way valve 206 is opened with smaller fluctuation amplitude, the liquid of the washing liquid is more stable, the liquid of the washing liquid is discharged with high frequency fluctuation, on the other hand, the problem of small single liquid discharge amount is overcome through the high frequency and small liquid discharge amount, on the other hand, the throwing of the washing liquid is finer, the controllability is better, and the throwing amount is more accurate.

The principle of the reciprocating vibration of the rotor 4 in the sleeve cavity 203 is as follows:

the rotor 4 is at least partially composed of magnetic conductive substances and can be arranged as a metal rod or the like, so that the rotor 4 generates magnetic driving force under the action of a magnetic field generated by a coil; of course, in order to reduce the mass of the mover 4, the mover 4 may be provided in a hollow, partially hollowed-out structure or the like. The mover 4 is reciprocated in the axial direction of the sleeve chamber 203 by the magnetic driving force of the coil 501 and the elastic force of the elastic member 3.

In the invention, direct current or alternating current is supplied to the coil 501, and the elastic element 3 is matched to drive the rotor 4 to make reciprocating vibration in the sleeve cavity 203, and the direct current and the alternating current are respectively supplied to the coil 501 through specific embodiments.

In an embodiment of the present invention, an implementation manner of the washing liquid dispenser is as follows:

a direct current is applied to the coil 501, the coil 501 is disposed around the mover 4 in the circumferential direction of the mover 4, and the coil 501 constitutes a closed circuit. When the coil 501 is energized, a magnetic field is generated, and the magnetic field generates an attractive force to the mover 4 as a magnetic driving force of the coil 501 to the mover 4.

The magnetic driving force drives the mover 4 to move toward the elastic member 3 and presses the elastic member 3. The magnitude of the magnetic driving force can be indirectly controlled by controlling the magnitude of the current, the magnetic driving force of the coil 501 can be increased or reduced, and the coil 501 can generate the magnetic driving force to the rotor 4 or vanish the magnetic driving force by controlling the on-off of the current. After the elastic element 3 is extruded, deformation occurs, when the elastic element 3 is pressed to reach a limit position, the rebound force is maximum, the elastic element 3 can not be compressed any more, the mover 4 stops moving, the stress balance of the mover 4 is achieved, at the moment, the control coil 501 is powered off, or the magnetic driving force of the coil 501 is reduced, the stress balance of the mover 4 is broken, the elastic element 3 rebounds the mover 4, the mover 4 moves reversely along the direction away from the elastic element 3, after the mover 4 moves reversely, the control coil 501 is powered on, or the magnetic driving force of the coil 501 is increased, the mover 4 is subjected to the magnetic driving force of the coil 501, and moves forward, so that the mover 4 is continuously subjected to the magnetic driving force and the rebound force, and vibrates reciprocally along the axial direction of the sleeve cavity 203.

In an embodiment of the present invention, a further implementation manner of the washing liquid dispenser is as follows:

to coil 501 lets in alternating current, coil 501 sets up along the circumference of rotor 4 around rotor 4, and coil 501 constitutes closed loop, because alternating current constantly changes, leads to the magnetic drive force of coil 501 constantly to change, through the principle that alternating current was to rotor 4 drive:

in one cycle of the alternating current, there are two peaks of current/voltage, and when the peak of current/voltage is present, the magnetic driving force of the coil 501 on the mover 4 is maximum.

In the first quarter period, the current gradually reaches a peak value from zero, the magnetic driving force gradually increases from zero to a maximum value, and in the process of continuously increasing the magnetic driving force, the compression amount of the mover 4 on the elastic element 3 gradually increases, namely the magnetic driving force drives the mover 4 to continuously squeeze the elastic element 3 to move towards the elastic element 3, so that the forward driving of the mover 4 is realized;

in the second quarter period, the current gradually decreases from the maximum value to zero, the magnetic driving force is continuously reduced, the mover 4 moves away from the elastic element 3 under the action of the rebound force of the elastic element 3, and the mover 4 is driven by the rebound force, so that the reverse driving of the mover 4 is realized.

The mover 4 is simultaneously subjected to magnetic driving force and elastic force, and the resultant force of the magnetic driving force and the elastic force drives the mover 4 to move forward in the first quarter period, and the resultant force of the magnetic driving force and the elastic force drives the mover 4 to move backward in the second quarter period.

The principle on which the mover 4 is driven by the alternating current is described above, and in actual circumstances, since the mover 4 reciprocates, there is a forward or reverse speed;

in the first quarter cycle, the magnetic driving force is continuously increased, the rotor 4 continuously moves forward and has a forward speed, when the magnetic driving force reaches a peak value and is about to be reduced, namely, the moment when the first quarter cycle is ended, the rotor 4 continues to move forward due to the forward speed of the rotor 4, and the time from the moment when the first quarter cycle is ended to the moment when the forward speed of the rotor 4 is zero is stopped, the time can be called as a braking time, and the time occupies the second quarter cycle, namely, the time when the second quarter cycle is started, the rotor 4 does not move in the reverse direction but continues to move in the forward direction until the speed is reduced to zero;

the second quarter period has the effect that the elastic element 3 drives the rotor 4 to move reversely, so that the rotor 4 has better reciprocating vibration effect, and the braking time needs to be properly controlled, at least the braking time is smaller than one quarter period; the situation that the mover 4 continuously moves forward and cannot move reversely in the whole period is avoided, so that the mover can only move unidirectionally and cannot reciprocate, and liquid can not enter and exit through reciprocating vibration.

The braking time can be controlled to be proper time by adjusting the elastic coefficient of the spring, the magnetic driving force, the mass of the rotor 4 and the displacement length of the reciprocating vibration.

By means of a suitable "braking time", the time of the mover 4 moving in the forward direction or the time of the mover 4 moving in the reverse direction in each quarter cycle can be controlled, i.e. the mover 4 is controlled to perform one reciprocating vibration in each half cycle.

The mover 4 performs one reciprocating vibration in each half cycle, and performs two reciprocating vibrations in the whole cycle.

Preferably, the rotor 4 is movably arranged in the middle of the sleeve cavity 203 through the magnetic driving force of the coil 501 and the resilience force of the elastic element 3, so that the rotor 4 vibrates in the middle area of the sleeve cavity 203, the washing liquid at two sides of the rotor 4 in the sleeve cavity 203 is subjected to the vibration action of the rotor 4, the vibration effect of the rotor 4 is maximized, and the liquid inlet and the liquid outlet of the washing liquid are facilitated.

According to the invention, the coil 501 and the elastic element 3 enable the rotor 4 to vibrate reciprocally in the sleeve cavity 203, and the rotor 4 drives the washing liquid to fluctuate, so that liquid inlet and liquid outlet are realized. In the invention, a diversion channel for the washing liquid to pass through is formed between the periphery of the rotor 4 and the inner wall of the sleeve cavity 203, so that the washing liquid can move along the periphery of the sleeve cavity 203 to realize liquid feeding and liquid discharging, and on the other hand, the diversion channel isolates the rotor 4 from the inner wall of the sleeve cavity 203, so that friction with the inner wall of the sleeve cavity 203 is avoided when the rotor 4 acts, abrasion of the rotor 4 is avoided, the effect of liquid feeding and liquid discharging cannot be influenced due to abrasion of the rotor 4, the service life is effectively prolonged, and the device is suitable for long-time use.
