Description

Control method of dispenser of washing equipment

Technical Field

The invention belongs to the technical field of washing equipment, and particularly relates to a control method of a dispenser of the washing equipment.

Background

With the rapid development of washing machine technology, the degree of automation of washing machines is increasing. Most of the current washing machines are equipped with an automatic detergent adding function, which is convenient for users to wash clothes. The common detergent throwing device is generally provided with a detergent storage container in the washing machine, and before the washing machine washes, the adding amount of the detergent is judged according to the weighing information of the washing machine, and the detergent is pumped into a washing machine barrel through a pump body such as a piston pump, a centrifugal pump, a peristaltic pump and the like, so that the automatic adding of the detergent is realized.

The detergent dispensing device has different dispensing efficiencies due to the different concentrations of different types of detergents. And the detergent in the detergent storage container cannot be completely put in, is easy to remain in the container, and is mixed with other detergents, so that the washing effect is affected. In addition, the existing automatic detergent feeding device has the problems of low feeding precision, poor reliability and the like.

The Chinese patent with application number 202020552932.8 discloses an automatic liquid detergent feeding device which comprises an elastic accommodating body and an electromagnetic valve. The elastic accommodating body comprises an elastic side wall and a sealed bottom wall, the open end of the elastic side wall is connected to the mounting bracket in a sealing way, the closed end of the elastic side wall is closed by the sealed bottom wall, and the elastic side wall, the supporting seat and the sealed bottom wall jointly define an accommodating chamber with variable volume. The mounting bracket is provided with a liquid suction port and a liquid discharge port at intervals, wherein the liquid suction port is communicated with the storage chamber, and the liquid discharge port is communicated with the throwing chamber. The outer wall of sealed diapire is connected in the valve rod of solenoid valve, and after the solenoid valve circular telegram, the valve rod moves backward under the effect of magnetic force to the sealed diapire of pulling elasticity accommodation body moves backward, and the elasticity lateral wall is stretched, holds the cavity volume grow. After the electromagnetic valve is powered off, the magnetic force disappears, the elastic accommodating body contracts and returns to the initial state under the action of self-elasticity, and the volume of the accommodating cavity is reduced.

According to the application, the elastic accommodating body is arranged, and the liquid suction or liquid discharge is realized by utilizing the deformation of the accommodating cavity enclosed by the elastic accommodating body. However, the pressure generated by deformation of the accommodating chamber is insufficient to completely discharge the residual detergent in the chamber, and the problem of low dispensing efficiency still remains.

In view of this, the present invention has been made.

Example 1

The embodiment provides a control method of a dispenser of washing equipment. The dispenser comprises a driving device and a dispensing device.

As shown in fig. 1, the drive means is arranged within the housing 2 of the dispenser. The driving means comprises a sleeve 202, a coil 501 arranged outside the sleeve 202 and a mover 4 arranged inside the sleeve 202.

The coil 501 is a ring-shaped wire winding.

In one version of this embodiment, coils 501 are coaxially disposed on either side of sleeve 202.

The axial direction described herein is understood to be the direction along the central axis of the housing. Specifically, the coil 501 is axially disposed within the housing 2. The coils 501 are arranged coaxially with the sleeve 202 and distributed on both sides of the sleeve 202. The winding directions of the energizing wires of the coils 501 at the two sides are the same, so that the same magnetic field direction is formed after the coils 501 are energized, and the same driving force is provided for the movement of the mover 4 in the sleeve 202.

In addition, the coils 501 on both sides of the sleeve 202 are spaced apart from both side walls in the axial direction of the sleeve 202. The distance is set, so that magnetic force generated after the coil 501 is electrified can be widely applied to the mover 4 in the sleeve 202, the utilization rate of the magnetic force is improved, and sufficient driving force is provided for the movement of the mover 4.

In another version of this embodiment, the coil 501 is disposed on only one side of the sleeve 202 in the axial direction. By increasing the number of turns of the coil 501, the magnetic field force generated after the coil 501 is energized can be increased, and the requirement for supplying the driving force to the mover 4 can be satisfied. The number of turns, number and distribution position of the coils 501 can be adaptively adjusted according to specific use requirements.

The mover 4 is a metal block made of a metal material such as steel or iron, which is movable by a magnetic force.

In the present embodiment, the mover 4 is axially mounted in the sleeve 202 and is axially disposed in parallel with the sleeve 202. The mover 4 is axially movable within the sleeve 202.

Further, the two co-axial sides of the mover 4 are not attached to the sleeve 202. It will be appreciated that the two co-axial sides of the mover 4 are spaced from the two axial side walls of the sleeve 202, so as to facilitate the movement of the mover 4 along the axial direction of the sleeve 202. And one end of the mover 4 near the bottom of the sleeve 202 is spaced from the bottom of the sleeve 202 to provide a movable space for the mover 4 to move in the sleeve 202.

In the present embodiment, the mover 4 has an initial position. The initial position is that the position of the mover 4 is right side in the middle of the coil 501, and ensures that the electromagnetic attraction force of the coil 501 moves the mover 4 toward the left side. In addition, the size of the mover 4 can be adaptively adjusted according to specific use requirements.

Further, sleeve 202 has an axial opening on the aspiration lumen 602 side.

The sleeve 202 is mounted in the housing 2 to provide a mounting and movable space for the mover 4. Sleeve 202 has an opening disposed at one axial end of sleeve 202 and adjacent one side of aspiration lumen 602.

Further, the dispensing device comprises a membrane 1 and a pipetting chamber 602.

The pipette chamber 602 herein refers to a chamber for storing liquid. Specifically, as shown in fig. 1, the pipette chamber 602 communicates with the pipette 603 and the drain 204. The pipette 603 communicates with the cartridge for drawing liquid from the cartridge. Drain 204 is connected to a detergent box or a waterway, and supplies the liquid in liquid suction chamber 602 to the detergent box or directly supplies the liquid to the waterway for dilution.

In the present embodiment, the pipette 603 and the drain pipe 204 are each provided with a check valve 206. Wherein the opening of the one-way valve 206 in the pipette 603 is directed towards the pipetting chamber 602 such that the pipette 603 can only aspirate liquid from the cartridge. The opening of the check valve 206 in the drain 204 is directed to the outside of the pumping chamber 602 so that the drain 204 can only drain the liquid in the pumping chamber 602, preventing the liquid in the drain 204 from flowing back.

Further, a membrane 1 is provided between the housing 2 and the pipetting chamber 602. The first end of the mover 4 is arranged in connection with the diaphragm 1 through the opening of the sleeve 202.

The first end of the mover 4 refers to the end of the mover 4 near the diaphragm 1, i.e. the right end of the mover 4 in fig. 1.

The membrane 1 here refers to a flexible sheet or membrane made of rubber, silicone, polyurethane, or the like.

In this embodiment, as shown in FIG. 1, the diaphragm 1 is disposed between the housing 2 and the liquid suction chamber 602. Specifically, one side of the diaphragm 1 is disposed adjacent to the housing 2, and the other side is disposed within the liquid suction chamber 602. The opening of the sleeve 202 corresponds to the intermediate region of the diaphragm 1, and a space is formed in which the diaphragm 1 deforms into the sleeve 202.

The control method comprises the following steps:

s1, starting a putting program of washing equipment; a coil 501 in the driving device is electrified with alternating current to generate magnetic field force to drive the rotor 4 to move so as to deform the diaphragm;

s2, resetting the rotor 4 and the diaphragm at least under the action of resilience force;

s3, the liquid suction cavity 602 sucks liquid and discharges liquid under the resonance oscillation action of the rotor 4 and the diaphragm.

As described above, the mover 4 is driven to move by the magnetic force, the diaphragm 1 is driven to deform repeatedly, and the pressure in the liquid suction cavity 602 is changed under the action of the elastic force of the diaphragm 1, and the liquid suction cavity 602 is driven to suck and discharge liquid by using the pressure difference, so that the automatic liquid feeding in the liquid suction cavity 602 is realized.

Further, step S1 includes S11, applying an alternating current to the coil 501, and generating a varying magnetic force along a direction in which the mover 4 approaches the center of the coil 501, so as to drive the mover 4 to deform the diaphragm 1 to the first deformation.

In this embodiment, the process of generating magnetic field force after the coil 501 is energized with alternating current is understood as that the current flowing into the coil 501 is directed in the counterclockwise direction of the coil 501 when viewed from the bottom side in the axial direction of the sleeve (the left side in the axial direction of the sleeve). According to the ampere rule (holding the energized solenoid with the right hand, letting the four fingers point in the direction of the current, then the end pointed by the thumb is the N pole of the energized solenoid), the coil 501 generates an axial leftward magnetic force upon energization. That is, the direction of the magnetic field is the direction in which the mover 4 approaches the center of the coil 501.

The first deformation mentioned here means that the mover 4 and the diaphragm 1 deform in the axial leftward direction under the action of the magnetic force to the maximum deformation amount of the mover 4 and the diaphragm 1.

Step S2 includes S21, where deformation of the diaphragm 1 generates a repulsive force opposite to the direction of the magnetic force.

Specifically, since the diaphragm 1 itself has elasticity, a repulsive force can be generated after deformation. At this time, the elastic force means a force generated after the membrane 1 is deformed, and returns the membrane 1 to the undeformed state. The direction of the spring force is opposite to the direction in which the membrane 1 is deformed, that is, the direction of the spring force is opposite to the direction of the magnetic field force.

Further, the resilience force overcomes the magnetic force, and drives the diaphragm 1 and the mover 4 to return to the second deformation.

The second deformation means that the mover 4 and the diaphragm 1 are restored from the maximum deformation amount in the direction opposite to the deformation direction, and the restored maximum deformation amount exceeds the initial positions of the mover 4 and the diaphragm 1. The direction of the second deformation is opposite to the direction of the first deformation. The distance of the second deformation is greater than the distance of the first deformation, and it is understood that the distance of the deformation of the diaphragm 1 in the direction in which the mover 4 coincides with the center of the coil 501 is smaller than the distance of the reset of the diaphragm 1 in the direction of the initial position.

Specifically, the magnetic force continuously applies work to the mover 4, and drives the mover 4 to move in the direction of deformation of the diaphragm 1. Because the resilience force of the diaphragm 1 is opposite to the direction of the magnetic field, the resilience force changes along with the deformation of the diaphragm 1 until the magnetic field can be overcome, and the diaphragm 1 is driven to drive the mover 4 to reset.

In step S3, the liquid suction chamber 602 sucks and discharges liquid by the resonance oscillation of the mover 4 and the diaphragm 1.

Specifically, the magnetic field force changes periodically, and under the action of the magnetic field force and the rebound force, the mover 4 and the diaphragm 1 can realize high-frequency reciprocating motion. The changing magnetic force and the resilience force of the diaphragm 1 repeatedly drive the deformation or resetting of the mover 4 and the diaphragm 1, and finally resonance oscillation is generated.

In a specific implementation process, the mover 4 receives an axial leftward magnetic force to drive the diaphragm 1 to move in the sleeve 202 along the axial leftward direction, so as to increase the area in the liquid suction cavity 602. The pressure in the pipette chamber 602 is reduced to form a negative pressure, and the liquid is pumped through the pipette 603. The mover 4 and the diaphragm 1 are reset, the liquid suction cavity 602 is extruded, the area in the liquid suction cavity 602 is reduced, the pressure in the liquid suction cavity 602 is increased, and the liquid is discharged out of the liquid suction cavity 602 through the liquid discharge pipe 204.

As described above, the diaphragm 1 can generate elastic vibration during repeated deformation due to the elasticity of the diaphragm 1 itself. The mover 4, which reciprocates at a high frequency, can increase the vibration amplitude of the diaphragm 1, thereby improving the liquid sucking and discharging ability of the liquid sucking chamber 602.

Example two

This embodiment is a further description of the first embodiment described above.

Further, step S1 includes: and S13, when the first deformation is larger than the magnetic field force, the diaphragm 1 has a movement trend opposite to the direction of the magnetic field force.

The first deformation mentioned here includes the maximum deformation amount of the mover 4 and the diaphragm 1 in the direction approaching the center of the coil 501.

Specifically, when the first deformation of the mover 4 and the diaphragm 1 reaches the maximum deformation amount, the repulsive force reaches the maximum at this time, and the repulsive force is larger than the magnetic force. The resilience force can completely overcome the magnetic field force, and the driving membrane 1 starts to drive the rotor 4 to reset towards the second deformation direction. That is, when the first deformation of the diaphragm 1 reaches a repulsive force greater than the magnetic field force, the diaphragm 1 has a movement tendency to return to the second deformation direction. Alternatively, the membrane 1 has a tendency to move in a direction opposite to the magnetic force.

Further, step S2 includes S23, the second deformation is moved to the initial position, and the inertial force overcomes the magnetic force, so as to drive the mover 4 and the diaphragm 1 to move beyond the initial position to the second deformation.

The second deformation referred to herein means that the mover 4 and the diaphragm 1 are restored from the maximum deformation amount of the first deformation to the opposite direction to the first deformation direction, and the restored maximum deformation amount exceeds the initial positions of the mover 4 and the diaphragm 1.

In the second deformation process, the mover 4 and the diaphragm 1 return to the original positions by the resilience force. Since the mover 4 and the diaphragm 1 have weights, there must be an inertial force of continued movement. In the initial position, the inertial force can overcome the magnetic field force, and the mover 4 and the diaphragm 1 are driven to move beyond the initial position in the second deformation direction until the maximum deformation amount of the second deformation is reached.

Example III

This embodiment is a further description of the second embodiment described above.

Further, step S1 includes step S14, during the first deformation, the magnetic force and the repulsive force gradually increase, and the magnetic force is greater than the repulsive force.

The first deformation referred to herein may be a deformation process of the mover 4 and the diaphragm 1 in a first deformation direction. The elastic force means the elastic force of the membrane 1.

Specifically, in one period of the ac voltage, the voltage is increased and then decreased. The coil 501 is energized with alternating current and the resulting magnetic field force is varied. During the first deformation, the voltage is in an increasing stage, and the mover 4 approaches the center of the coil 501, and the magnetic force applied to the mover 4 gradually increases. The deformation amount of the diaphragm 1 is gradually increased, so that the resilience force generated by the deformation of the diaphragm 1 is also gradually increased. In the first deformation process, the magnetic force is larger than the rebound force, and overcomes the rebound force to drive the mover 4 and the diaphragm 1 to move towards the first deformation direction.

Further, step S2 includes S24, during the second deformation, the magnetic force, the resilience force, and the inertial force gradually decrease, and the sum of the resilience force and the inertial force is greater than the magnetic force.

Specifically, during the second deformation, the voltage is in a decreasing phase and the magnetic field force gradually decreases. The resilience force is gradually reduced as the membrane 1 is reset after deformation. The inertial forces of the mover 4 and the diaphragm 1 also gradually decrease during the resetting. The sum of the resilience force and the inertia force is larger than the magnetic field force, and the resilience force and the inertia force overcome the magnetic field force together to drive the mover 4 and the diaphragm 1 to return to the second deformation direction.

Further, the movement speed of the mover 4 and the diaphragm 1 in the first deformation direction increases and then decreases.

Specifically, during the first deformation process, the membrane 1 has no resilience before deformation. At this time, the relative value of the magnetic force and the repulsive force is large, so that the moving speed of the mover 4 and the diaphragm 1 starts to be increased. As the repulsive force increases, the relative value of the magnetic force and the repulsive force decreases, and the moving speed of the mover 4 and the diaphragm 1 starts to slow down.

Further, the movement speed of the mover 4 and the diaphragm 1 in the second deformation direction increases and then decreases.

Specifically, in the second deformation process, the resilience force reaches the maximum before the diaphragm 1 is not restored. At this time, the relative values of the magnetic force, the repulsive force and the inertial force are large, and the moving speed of the mover 4 and the diaphragm 1 is increased. As the repulsive force and the inertial force decrease, the relative values of the magnetic field force and the repulsive force and the inertial force decrease, and the moving speed of the mover 4 and the diaphragm 1 slows down.

Example IV

This embodiment is a further description of the third embodiment described above.

Further, step S14 includes S141, where the resultant force of the magnetic force and the repulsive force increases before the mover 4 approaches the center of the coil 501.

Specifically, when the coil 501 is energized to generate a magnetic field force, the magnetic induction line density at the center of the coil 501 is the most dense, and it is conceivable that the magnetic field force is larger near the center of the coil 501. When the mover 4 approaches the center of the coil 501, the magnetic field force applied to the mover 4 gradually increases, and the relative value of the magnetic field force and the repulsive force is large. It is conceivable that the resultant force of the magnetic force and the repulsive force is increasing, so that the moving speed of the mover 4 and the diaphragm 1 is increasing. The direction of the resultant force referred to herein is the same as the direction of the magnetic force.

Further, after the mover 4 exceeds the center of the coil 501, the resultant force of the magnetic force and the repulsive force is reduced. Specifically, after the mover 4 is far from the center of the coil 501, the magnetic force applied to the mover 4 gradually decreases and the repulsive force gradually increases. It is conceivable that the resultant force of the magnetic force and the repulsive force is reduced and the moving speed of the mover 4 and the diaphragm 1 is reduced.

Further, step S2 includes: s241, the resultant force of the repulsive force, the inertial force and the magnetic field force increases before the mover 4 approaches the center of the coil 501. The direction of the resultant force is opposite to the direction of the magnetic force.

Specifically, the relative value of the repulsive force and the magnetic field force is large before the mover 4 approaches the center of the coil 501. It is conceivable that the resultant force of the magnetic force with the repulsive force and the inertial force increases, and the moving speed of the mover 4 and the diaphragm 1 increases. The direction of the resultant force referred to herein is opposite to the direction of the magnetic force.

Further, after the mover 4 exceeds the center of the coil 501, the resultant force of the repulsive force, the inertial force and the magnetic field force is reduced.

Specifically, after the mover 4 exceeds the center of the coil 501, the relative values of the repulsive force and the inertial force and the magnetic field force are small. It is conceivable that the resultant force of the magnetic force with the repulsive force and the inertial force is reduced and the moving speed of the mover 4 and the diaphragm 1 is reduced.

Example five

This embodiment is a further description of the fourth embodiment described above.

Further, step S1 includes: s15, in the first deformation, the speeds of the rotor 4 and the diaphragm 1 to the first deformation are zero, and the direction of the resultant force is opposite to the direction of the magnetic field force.

Specifically, in the first deformation process, when the mover 4 and the diaphragm 1 reach the maximum deformation amount of the first deformation, the movement speed is zero. At this time, the direction of the resultant force received by the diaphragm 1 is opposite to the direction of the magnetic field, and has a movement tendency opposite to the first deformation direction.

Further, step S2 includes: s25, in the second deformation, the speeds of the mover 4 and the diaphragm 1 to the second deformation are zero, and the direction of the resultant force is the same as the direction of the magnetic force.

Specifically, in the second deformation process, when the mover 4 and the diaphragm 1 reach the maximum deformation amount of the second deformation, the movement speed is zero. At this time, the direction of the resultant force received by the diaphragm 1 is the same as the direction of the magnetic field force, and has a movement tendency opposite to the second deformation direction.

Example six

This embodiment is a further description of the first embodiment described above. As shown in fig. 2, the bottom of the sleeve 202 in the drive device is provided with a resilient element 3. The elastic element 3 is arranged at a distance from or in contact with the mover 4.

In this embodiment, one end of the elastic element 3 is fixedly connected to the bottom of the sleeve 202.

The elastic element 3 is a member that generates a repulsive force when receiving a force. The elastic member 3 may be various resilient members such as coil springs and rubber springs. Preferably, in this embodiment, the elastic element 3 is a coil spring. The length and volume of the elastic element 3 can be adapted according to specific use requirements.

One end of the elastic element 3 is fixedly connected with the bottom of the sleeve 202, so that the elastic element 3 is fixedly arranged in the sleeve 202. The fixed connection can be in various connection forms such as bonding, clamping and the like, and is not limited herein. Preferably, the elastic element 3 is arranged in the middle region of the bottom of the sleeve 202. One end of the elastic element 3 is connected to the middle area of the bottom of the sleeve 202, so that a sufficient moving space is provided for the mover 4 later.

In one version of this embodiment, the other end of the elastic element 3 is spaced apart from the second end of the mover 4.

The second end of the mover 4 described herein may be understood as the end of the mover 4 remote from the diaphragm 1.

The other end of the elastic element 3 is arranged at a distance corresponding to the end of the mover 4 away from the diaphragm 1, i.e. a certain distance is left between the elastic element 3 and the mover 4. By setting the distance, the mover 4 can have a sufficient moving distance, and the deformation amount of the diaphragm 1 can be increased.

In another version of this embodiment, the other end of the elastic element 3 is connected to the second end of the mover 4.

Specifically, the other end of the elastic element 3 is connected with the end of the mover 4 away from the diaphragm 1, so that the distance that the mover 4 compresses the elastic element 3 is increased, the deformation of the elastic element 3 is increased, and a larger resilience force is provided.

Further, the coil 501 is energized with an alternating current to generate a magnetic field force changing along the direction that the mover 4 approaches the center of the coil 501, and the mover 4 is driven to drive the diaphragm 1 and compress the elastic element 3 to deform to the first deformation.

The first deformation here means that the diaphragm 1 and the elastic member 3 deform in the axial leftward direction under the effect of the magnetic field force to the maximum deformation amount of the elastic member 3 and the diaphragm 1. The direction of the first deformation is the direction in which the mover 4 approaches the center of the coil 501.

In a specific implementation, the magnetic force acting axially to the left drives the mover 4 to drive the diaphragm 1 to stretch, and when the mover 4 moves in the sleeve 202, it contacts the elastic element 3 and starts to compress the elastic element 3 until the maximum deformation of the elastic element 3 and the diaphragm 1 is reached.

Further, the deformation of the diaphragm 1 and the elastic member 3 generates a repulsive force against the direction of the magnetic force.

After the elastic element 3 and the diaphragm 1 reach the maximum deformation, the return to the initial position direction is started. While the coil 501 is continuously energized, the magnetic force is always present and continuously attracts the mover 4 in the direction of the magnetic force. Since the elastic member 3 and the diaphragm 1 themselves have elasticity, a repulsive force opposite to the deformation direction can be generated. The direction of the spring force is also opposite to the direction of the magnetic field force.

Further, the resilience force overcomes the magnetic force, and drives the mover 4 and the diaphragm 1 or the mover 4, the diaphragm 1 and the elastic element 3 to return to the second deformation.

In particular, the resilience varies during deformation of the elastic element 3 and the membrane 1. When the elastic element 3 and the diaphragm 1 reach the maximum deformation amount, the resilience force can overcome the magnetic field force, and the elastic element 3 and the diaphragm 1 are driven to drive the mover 4 to return to the second deformation direction.

As described above, the mover 4, the elastic member 3 and the diaphragm 1 are restored by the repulsive force against the magnetic field force in the opposite direction. Therefore, the elastic element 3 is provided, so that the vibration amplitude of the diaphragm 1 during resetting is effectively increased, the resetting capability of the mover 4 and the diaphragm 1 is improved, and the deformability of the liquid suction cavity 602 is further improved.

Example seven

This embodiment is a further description of the above-described sixth embodiment.

Further, step S1 includes: and S13, when the first deformation is larger than the magnetic field force, the diaphragm 1 and the elastic element 3 have movement trends opposite to the magnetic field force direction.

The first deformation mentioned here includes the maximum deformation amount of the mover 4, the diaphragm 1 and the elastic member 3 in the direction approaching the center of the coil 501.

Specifically, when the first deformation of the mover 4, the diaphragm 1 and the elastic member 3 reaches the maximum deformation amount, the repulsive force reaches the maximum at this time, and the repulsive force is larger than the magnetic force. The resilience force can completely overcome the magnetic field force, and the diaphragm 1 and the elastic element 3 are driven to drive the mover 4 to return to the second deformation direction.

Further, step S2 includes S23, the second deformation is moved to the initial position, and the inertial force overcomes the magnetic force, so that the mover 4, the diaphragm 1 and the elastic element 3 are driven to move further to the second deformation beyond the initial position.

The second deformation referred to herein means that the mover 4, the diaphragm 1 and the elastic member 3 are restored from the maximum deformation amount of the first deformation to the opposite direction to the first deformation direction, and the restored maximum deformation amount exceeds the initial positions of the mover 4, the diaphragm 1 and the elastic member 3.

In the second deformation process, the mover 4, the diaphragm 1 and the elastic member 3 return to the original positions by the resilience. Since the mover 4, the diaphragm 1 and the elastic member 3 have weights, there must be an inertial force of continued movement. In the initial position, the inertial force is able to overcome the magnetic field force and continue to drive the mover 4, the diaphragm 1 and the elastic element 3 beyond the initial position in the second deformation direction until the maximum deformation amount of the second deformation is reached.

Example eight

This embodiment is a further description of the seventh embodiment described above.

The first deformation referred to herein may be a deformation process of the mover 4, the diaphragm 1 and the elastic member 3 in a first deformation direction. The elastic force means the elastic force of the membrane 1 and the elastic member 3.

Specifically, in one period of the ac voltage, the voltage is increased and then decreased. The coil 501 is energized with alternating current and the resulting magnetic field force is varied. During the first deformation, the voltage is in an increasing stage, and the mover 4 approaches the center of the coil 501, and the magnetic force applied to the mover 4 gradually increases. The deformation amounts of the diaphragm 1 and the elastic element 3 are gradually increased, so that the resilience generated by the deformation of the diaphragm 1 and the elastic element 3 is also gradually increased. In the first deformation process, the magnetic force is larger than the rebound force, and overcomes the rebound force to drive the mover 4, the diaphragm 1 and the elastic element 3 to move towards the first deformation direction.

Specifically, during the second deformation, the voltage is in a decreasing phase and the magnetic field force gradually decreases. The resilience force is gradually reduced as the membrane 1 and the elastic member 3 are restored after being deformed. The inertial forces of the mover 4, the diaphragm 1 and the elastic element 3 also gradually decrease during the resetting. The sum of the resilience force and the inertia force is larger than the magnetic field force, and the resilience force and the inertia force overcome the magnetic field force together to drive the mover 4, the diaphragm 1 and the elastic element 3 to return to the second deformation direction.

Further, the movement speed of the mover 4, the diaphragm 1 and the elastic member 3 in the first deformation direction increases and decreases.

Specifically, during the first deformation process, the diaphragm 1 and the elastic element 3 have no elastic force before deformation. At this time, the relative value of the magnetic force and the repulsive force is large, so that the moving speeds of the mover 4, the diaphragm 1 and the elastic member 3 start to be increased. As the repulsive force increases, the relative value of the magnetic force and the repulsive force decreases, and the moving speed of the mover 4, the diaphragm 1 and the elastic member 3 starts to slow down.

Further, the moving speeds of the mover 4, the diaphragm 1 and the elastic member 3 in the second deformation direction are increased and then decreased.

Specifically, during the second deformation, the resilience is maximized before the diaphragm 1 and the elastic member 3 are not restored. At this time, the relative values of the magnetic force, the repulsive force and the inertial force are large, and the moving speeds of the mover 4, the diaphragm 1 and the elastic member 3 are increased. As the repulsive force and the inertial force decrease, the relative values of the magnetic field force and the repulsive force and the inertial force decrease, and the moving speeds of the mover 4, the diaphragm 1 and the elastic member 3 slow down.

Example nine

This embodiment is a further description of the above embodiment eight.

Specifically, when the coil 501 is energized to generate a magnetic field force, the magnetic induction line density at the center of the coil 501 is the most dense, and it is conceivable that the magnetic field force is larger near the center of the coil 501. When the mover 4 approaches the center of the coil 501, the magnetic field force applied to the mover 4 gradually increases, and the relative value of the magnetic field force and the repulsive force is large. It is conceivable that the resultant force of the magnetic force and the repulsive force is increasing, so that the moving speeds of the mover 4, the diaphragm 1 and the elastic member 3 are increasing. The direction of the resultant force referred to herein is the same as the direction of the magnetic force.

Further, after the mover 4 exceeds the center of the coil 501, the resultant force of the magnetic force and the repulsive force is reduced. Specifically, after the mover 4 is far from the center of the coil 501, the magnetic force applied to the mover 4 gradually decreases and the repulsive force gradually increases. It is conceivable that the resultant force of the magnetic force and the repulsive force is reduced and the moving speeds of the mover 4, the diaphragm 1 and the elastic member 3 are reduced.

Specifically, the relative value of the repulsive force and the magnetic field force is large before the mover 4 approaches the center of the coil 501. It is conceivable that the resultant force of the magnetic force with the repulsive force and the inertial force increases and the moving speeds of the mover 4, the diaphragm 1 and the elastic member 3 increase. The direction of the resultant force referred to herein is opposite to the direction of the magnetic force.

Specifically, after the mover 4 exceeds the center of the coil 501, the relative values of the repulsive force and the inertial force and the magnetic field force are small. It is conceivable that the resultant force of the magnetic force with the repulsive force and the inertial force is reduced and the moving speeds of the mover 4, the diaphragm 1 and the elastic member 3 are reduced.

This embodiment is a further description of the above embodiment nine.

Further, step S1 includes: s15, in the first deformation, the speeds from the rotor 4, the diaphragm 1 and the elastic element 3 to the first deformation are zero, and the direction of the resultant force is opposite to the direction of the magnetic field force.

Specifically, in the first deformation process, when the mover 4, the diaphragm 1 and the elastic element 3 reach the maximum deformation amount of the first deformation, the movement speed is zero. At this time, the direction of the resultant force received by the diaphragm 1 and the elastic member 3 is opposite to the direction of the magnetic field, and has a movement tendency opposite to the first deformation direction.

Further, step S2 includes: s25, in the second deformation, the speeds from the mover 4, the diaphragm 1 and the elastic element 3 to the second deformation are zero, and the direction of the resultant force is the same as the direction of the magnetic force.

Specifically, in the second deformation process, when the mover 4, the diaphragm 1 and the elastic element 3 reach the maximum deformation amount of the second deformation, the movement speed is zero. At this time, the direction of the resultant force applied to the diaphragm 1 and the elastic member 3 is the same as the direction of the magnetic force, and has a movement tendency opposite to the second deformation direction.

Example eleven

Further, step S23 includes S231, after the diaphragm 1 and the elastic element 3 exceed the initial positions, continuing to move in the second deformation direction, and generating a repulsive force in the same direction as the magnetic force.

Specifically, in the second deformation process, after the diaphragm 1 and the elastic element 3 return to the initial positions, the diaphragm continues to move in the direction of the second deformation under the action of the inertial force, and after the deformation, a rebound force opposite to the direction of the second deformation is generated. That is, the direction of the spring force is the same as the direction of the magnetic force.

Further, in the course of the diaphragm 1 and the elastic member 3 continuing to deform beyond the initial position, the repulsive force gradually increases, and the inertial force gradually decreases. While the mover 4 is subjected to the magnetic force, it is conceivable that the inertial force is larger than the sum of the repulsive force and the magnetic force, and that the inertial force overcomes the repulsive force and the magnetic force, driving the diaphragm 1 and the elastic member 3 to continue to move to the maximum deformation amount of the second deformation.

Example twelve

Further, step S3 includes: s31, the coil 501 is continuously powered with alternating current, and the magnetic field force and the rebound force periodically drive the mover 4 to drive the diaphragm 1 to deform and reset, so that resonance oscillation is generated, the pressure in the liquid suction cavity 602 is changed, and the liquid suction cavity 602 is driven to suck and discharge liquid.

In a specific implementation process, the magnetic field force changes periodically, and under the action of the magnetic field force and the rebound force, the mover 4 and the diaphragm 1 can realize high-frequency reciprocating motion to generate resonance oscillation. Under the action of the resonance oscillation of the rotor 4 and the diaphragm 1, the pressure in the liquid suction cavity 602 is continuously changed, liquid suction and liquid discharge are periodically carried out, and the liquid feeding efficiency of the feeding device is effectively improved.

In one version of this embodiment, the vibration frequency of the diaphragm 1 is controlled by varying the mass of the mover 4, controlling the speed of movement of the mover 4 within the sleeve 202.

In a specific implementation process, the mass of the mover 4 is reduced, and the resonance frequency of the system can be increased, so that the movement speed of the mover 4 in the sleeve 202 is increased, the deformation of the diaphragm 1 is accelerated, and the vibration frequency of the diaphragm 1 is improved.

The frequency of the input voltage described herein can affect the amount of magnetic field force generated after passing into the coil 501.

The frequency of the input voltage is increased to increase the magnetic field force, at which time the mover 4 has a larger movement speed. That is, the number of times the diaphragm 1 is deformed increases in the same time, thereby increasing the vibration frequency of the diaphragm 1.

In this embodiment, when the liquid delivery amount is small, the liquid delivery amount m is 10ml, and the frequency of the input voltage is set to 10Hz. The automatic liquid feeding is realized, and the feeding time is T. When the liquid throwing amount M is 70ml, the input voltage frequency is set to be 30Hz, and the throwing time for realizing automatic throwing of liquid can be also T.

As a result, a large amount of liquid is dispensed within the same dispensing time T. The frequency of the input voltage is increased, the high-frequency reciprocating motion of the rotor 4 and the high-frequency vibration of the diaphragm 1 are realized, and the purpose of shortening the liquid throwing time is achieved.
