In the prior art, the slurry discharging assembly is provided with a slurry discharging valve, a rotatable valve core is arranged in the slurry discharging valve, and the valve core can rotate in the slurry discharging valve to open or close the slurry discharging assembly, so that the control function is realized. However, the valve core body in the scheme has an internal space, and when the valve core is in a closed state, slurry or waste water remained in the valve core has the risk of deterioration, so that bacteria are bred, and the normal use of a user is influenced. Meanwhile, the slurry discharging valve and the valve core need to occupy a slurry discharging space, and the slurry discharging space only plays a role in discharging slurry in the working process, so that the effective utilization rate of the machine is reduced, and the user experience satisfaction is reduced.

However, in such a solution, the magnetic ball for controlling the opening or closing of the duct is greatly affected by the outside, and can generally be used only for water or fluid close to water, and the fluid cannot be too large. If the density or viscosity of the fluid is high, the ball is greatly influenced by the fluid in the opening or closing process, the action is slow, and the pipeline cannot be opened or closed in time, so that the normal use of the valve is influenced; especially, when there is material in the fluid, such as residual bean particles in the process of processing soybean milk, the residual bean particles will be stuck between the ball and the pipeline, so that the ball can not normally close the pipeline and lose the corresponding function. The existing control scheme limits the position relation among all parts, and a small caliber can only be arranged below a magnetic ball to ensure that the small caliber can fall into a small caliber section under the action of gravity to seal a pipeline, so that the whole slurry discharge channel is required to be arranged only in the vertical direction. For the food processor product related to the application, the function of crushing processing needs to be met firstly, and the slurry discharge pipeline arranged in the vertical direction can seriously affect the natural crushing function of the product, particularly, materials falling on a vertical convenient upper small-caliber section can not be crushed normally, so that the processing effect of the food processor is greatly reduced. And the vertically arranged pulp discharge channel increases the height of the product; and the space-efficient utilization is reduced.

After the technical scheme is adopted, the utility model has the following advantages:

1. the slurry discharging assembly is provided with the slurry discharging channel, the stopping piece and the driving piece, wherein the slurry discharging channel is provided with the accommodating space, the stopping piece moves in the accommodating space to close the slurry discharging channel, and correspondingly, the driving piece is arranged outside the slurry discharging channel to magnetically drive the stopping piece to move in the accommodating space, so that the stopping piece moves to the closing position or leaves the closing position to open the slurry discharging channel, and further slurry in the slurry preparing cavity can flow out through the slurry discharging channel. Through preventing that the piece removes in accommodation space and seals or open arrange thick liquid passageway, control assembly does not need too big volume to realize, and the food preparation machine that significantly reduces sets up the shared space of valve module, promotes food preparation machine's space utilization. Set up accommodation space and supply to block the piece activity, and the driving piece externally blocks the piece with magnetic drive, and the driving piece can not directly set up in arranging the thick liquid passageway, receives the influence of thick liquid little, and the operational environment requirement to driving piece itself is low, and low-cost driving piece can satisfy the requirement, and the volume of driving piece self also need not to set up too greatly simultaneously. The stopping piece is driven by magnetism, can be controlled in a closed state and a non-closed state, can be quickly, efficiently and stably positioned in a closed position, and can be prevented from losing the closing function of the stopping piece; and when the stopping piece is in the non-closed state, the driving piece can control the stopping piece to be far away from the normal slurry discharging path of the slurry discharging channel, so that the slurry discharging channel can be opened to the maximum extent, and the slurry is discharged quickly. Moreover, when the stopping piece is in a closed state and the accommodating space is communicated with the pulping cavity, the accommodating space can also play a pulping cycle together with the pulping cavity, so that the common turbulence is played, the crushing performance is improved, and the space waste of the accommodating space is avoided. And the stopping piece relies on driving piece magnetic drive, requires greatly reduced to the space setting of stopping piece, and then accommodation space's position setting also can optimize the adjustment according to actual demand.

2. The stopping piece is arranged between the slurry outlet and the sealing opening, when the stopping piece needs to reach the sealing position, the stopping piece moves towards the sealing opening along the natural flowing direction of slurry, the resistance of the stopping piece to the movement of the sealing position can be reduced, the stopping piece can quickly reach the sealing position, and when the slurry discharging channel needs to be opened, the driving piece drives the stopping piece to leave the sealing position. Further, when the stopping piece is located at the closed position, the accommodating space is communicated with the pulping cavity through the pulp outlet, cooking processing of the pulping cavity can be participated, the processing environment is improved, and space waste of the accommodating space during closing is avoided.

3. The stop piece can move to the limit opening and at least partially shields the limit opening, so that the stop piece has the functions of completely sealing the slurry discharge channel and partially sealing the slurry discharge channel. For food processors, where different processing conditions are required for different cooking ingredients, for fluid cooking ingredients, such as soymilk, etc., the blocking member may completely close the discharge passage to prevent the discharge of the slurry from the discharge passage during normal operation; and when grinding the material futilely to processing, for example when grinding the rice futilely in order to process the ground rice, can seal the thick liquid passageway totally with arranging, directly take out the material or discharge through arranging the thick liquid passageway by the slurrying chamber when processing is accomplished, also can remove to spacing mouthful stopping the piece, the part shelters from spacing mouthful simultaneously, make spacing mouthful can be through little material for example kibbling ground rice, and the material of normal size, receive stopping of piece, and unable normal through spacing mouthful discharge slurrying chamber of discharging of spacing, and like this, the material is in kibbling the material of smashing good material synchronous discharge, the kibbling efficiency in the slurrying chamber has been promoted promptly, still can avoid kibbling material to be excessively processed after long-time crushing in the slurrying chamber. And even when processing fluid class edible material, for example when processing soybean milk, also can also be closed totally or partly earlier with preventing that the piece removes to the closing opening, and the material of only guaranteeing two can be normal gets into the slurrying intracavity, and can not get into accommodation space when throwing the material stage can. And when needs wash in advance to eating the material, prevent that the piece part shelters from spacing mouthful, the material can not spill from spacing mouthful, and the waste water of wasing the material can be discharged in step, promotes cleaning performance and speed, avoids opening again to open after having washed the material and close mouthful, and makes still remain the filth in the slurrying intracavity after wasing. Certainly, the stopping piece can also completely close the closed opening at the limiting opening to form a second closed position, on one hand, the communication between the accommodating space and the pulping cavity is prevented, and the completeness of the pulping cavity is ensured; on the other hand, the sealing states at different positions are particularly suitable for the self-cleaning process of the food processor, wherein the stopping piece is switched among different sealing positions, so that the pulping cavity can be conveniently cleaned, and the pulping component, particularly the accommodating space and the stopping piece can be cleaned when the positions are switched, so that the sanitary dead angle is avoided, and the safety and the sanitation of the food processor are ensured.

4. The containing space and the pulping cavity form a backflow cavity, and the pulp flows between the damaged pulping and the backflow cavity in the processing process to participate in circulation, so that the waste of the containing space is avoided, the pulping capacity of the pulping cavity can be improved, and the space utilization rate of the food processing machine is improved. Meanwhile, the backflow cavity participates in turbulence processing of the pulping cavity from the outside of the pulping cavity in the processing process, the liquid flow mode of the single pulping cavity can be changed, the crushing effect of the pulping cavity is further improved, and the food processing machine can finish cooking processing more quickly.

5. Set up gyration chamber and shrink chamber, the gyration chamber is transversely extending the setting, and the shrink chamber is located gyration chamber below, like this, the gyration chamber of horizontal setting transversely with make pulping chamber abundant backward flow and then participate in crushing processing, and because the gyration chamber does not have the difference in height at transverse direction and slurrying chamber, the thick liquid can not lead to the backward flow difficulty because of the difference in height when flowing between slurrying chamber and gyration chamber. Generally speaking, there is obvious difference in the volume ratio between the pulping chamber and the rotary chamber, when the pulp circulates in the pulping chamber, the pulping flowing through the pulp outlet drives the pulp in the pulp discharge channel to flow back to the pulping chamber, so that a pressure difference is formed between the rotary chamber and the pulping chamber, and the pulp in the rotary chamber is accelerated to flow back to the pulping chamber. The shrink chamber sets up in the below in gyration chamber, and when the closure state, the piece of preventing is located the shrink intracavity more, can occupy the great space of shrink intracavity, and the thick liquid volume that flows into the shrink intracavity is not many, can not influence crushing slurrying. Simultaneously, because the most space in the shrink chamber has been occupied to the prevention piece, the shrink chamber has less volume ratio in the gyration chamber relatively, the gyration chamber with the back flow in-process in pulping chamber, the thick liquid flows fast in the top in shrink chamber, drive the shrink chamber relatively gyration chamber and form the pressure differential, can take away from the shrink chamber with remaining thick liquid in the shrink chamber, and then participate in the course of working in gyration chamber and pulping chamber, can not influence food preparation machine's normal culinary art processing.

6. The stopping piece is located at the downstream of the sealing opening, the stopping piece moves towards the upstream side to seal the sealing opening, for a food processor, the stopping piece is usually in a sealing state all the time in the processing process, therefore, when the stopping piece is in a non-working state, the movement of the stopping piece cannot be influenced by materials, when the stopping piece needs to open the sealing opening to conduct the slurry discharge channel, the movement of the stopping piece is the same as the flowing direction of slurry, the stopping piece can quickly move towards an opening position to conduct the slurry discharge channel, and the slurry discharge speed is improved. And when the slurry discharging is finished and the cleaning process is finished, the same stopping piece can be quickly moved to be opened, so that the function of discharging the waste water is realized. Meanwhile, the accommodating space is arranged on the rear side of the closed opening, the requirement on the accommodating space is not high, only the accommodating stop piece is used for accommodating the accommodating stop piece, the occupied space is small, the normal processing of the pulping cavity is not influenced, and the space utilization rate of the food processing machine is improved. Simultaneously, the stop member is located the low reaches of closed end, when the stop member opened the thick liquid passageway, thick liquid can be earlier through the stop member, is discharged by the thick liquid passageway of arranging again, has avoided the thick liquid direct impact when arranging thick liquid passageway discharge, and the thick liquid flows more evenly gently.

7. The elastic sealing element is arranged between the accommodating space and the stopping element, and when the stopping element is in contact with the accommodating space to play a sealing function, the elastic sealing element can be extruded to strengthen the sealing effect, so that the failure of the sealing function of the stopping element is avoided. Meanwhile, the elastic sealing element reduces the size matching requirement between the stopping piece and the accommodating space, reduces the size requirement of the stopping piece and the accommodating space, and reduces the production and manufacturing cost of the food processor.

8. Further set up execution part and drive division, the effect that execution part can last prevents the piece, makes the piece of preventing can reach the operating condition of sealing or opening the mud discharging channel under controlled state, sets up the drive division, comes to drive the piece of preventing through execution part, prevents when the piece switches between encapsulated situation and non-encapsulated situation, can rely on the drive division to come the fast switch-over, only can rely on gravity when avoiding not having external drive power, switching time and switching state all can not be ensured.

9. The guide part is further arranged to limit the moving path of the executing part, so that the executing part can run on a more reliable stroke, and the stroke precision and the speed reliability of the executing part are guaranteed. Even if the stopping piece can reach the preset position through the driving part and the guide part, for example, the stopping piece can be controlled to reach the preset position between the closed state and the fully opened state by controlling the flow rate of the slurry in the slurry discharging process; or in the self-cleaning process of the food processor, the stop piece is controlled to partially open the pulp discharge channel, so that the waste water generated in the cleaning process can be discharged out of the pulping cavity through the pulp discharge channel, but the pulp discharge channel cannot be completely opened due to the stop action of the stop piece, and the waste of water source caused by complete discharge is reduced. And then the maximum stroke of the executing part moving to the closing direction along the guide part is set to be larger than the maximum stroke of the stopping part moving to the closing direction, namely, after the stopping part reaches the closing position contacted with the accommodating space, the executing part still has the stroke of moving to the closing direction, so that when the executing part reaches the final end position, the magnetic pulling force applied to the stopping part in the closing direction is continuously applied to the stopping part, the extrusion force between the stopping part and the inner wall of the accommodating space is increased, the closing effect between the stopping part and the inner wall of the accommodating space is strengthened, and compared with the prior art, the closing effect of the food processor can be ensured to the greater extent only by depending on the weight or the size of the stopping part.

Preferably, the stopper 3 is located between the grout outlet 24 and the closing port 23. It should be noted that, between the outlet 24 and the closing opening 23, it is located between the outlet and the closing opening in the flowing direction of the fluid, that is, when the fluid flows out from the outlet, the fluid will first pass through the blocking member and then flow through the closing opening, and similarly, the flowing of the fluid does not refer to the shortest distance, but refers to the cross section of the space through which the fluid can flow from the outlet to the closing opening, for example, a placing cavity is provided between the outlet and the closing opening, the blocking member can move into the placing cavity in the non-closing state, and the fluid or most of the fluid completely flows through the outside of the placing cavity, and at this time, the blocking member also belongs to the category between the outlet and the closing opening.

As shown in fig. 2-5, when the block member 3 is located at the closed position, the accommodating space between the slurry outlet and the block member 3 is communicated with the slurry making cavity 102 through the slurry outlet 24 to form a backflow cavity, and during the operation of the pulverizing assembly, the liquid in the backflow cavity flows with the liquid in the slurry making cavity 102 through the slurry outlet 24 to participate in the circulation pulverizing pulping.

When the stopping piece 3 is positioned in the placing cavity 26, the equivalent diameter of the flow section between the pulp discharge channel and the stopping piece is D1, and D1 is more than or equal to 4mm and less than or equal to 50 mm. If the D1 is too small, the maximum slurry discharge flow of the whole slurry discharge channel in the slurry discharge process is too small, the slurry discharge speed is too low, and the use experience of a user is influenced; if the D1 setting is too large, the discharge velocity is increased, but the volume of the discharge assembly is increased too much, resulting in wasted space. Preferably, the placing cavity 26 is further provided with a protrusion 261 at the bottom, or the placing cavity 26 expands outward compared with the contracting cavity 22 to form the protrusion 261 at the joint, the protrusion 261 can be used for supporting the blocking member 3 when the blocking member 3 moves to the placing cavity 26, so as to prevent the blocking member 3 from easily separating from the placing injury 26 and falling into the contracting cavity 22, and particularly when the blocking member 3 is impacted by the grout, the protrusion 261 enables the blocking member 3 to be reliably located in the placing cavity 26. Preferably, the placing cavity 26 is a spherical surface corresponding to the stopper 3, and the diameter of the placing cavity 26 is slightly larger than that of the stopper 3, wherein the placing cavity 26 is 2mm-5mm larger than that of the stopper 3. If the diameter difference is too small, when the size error exists between the blocking ball and the placing cavity, the possibility that the blocking ball cannot completely enter the placing cavity exists; if the diameter difference is too large, the gap between the placing cavity and the stopping ball is too large, and the placing effect cannot be well achieved.

The diameter of the pulp outlet 24 is smaller than that of the blocking piece 3, so that the blocking piece 3 does not enter the pulping cavity 102 through the pulp outlet 24 in the normal working process, and the blocking piece 3 is prevented from interfering the normal crushing of the crushing knife 103. Optionally, the diameter of the slurry outlet 24 is larger than the diameter of the closing ball 31 and smaller than the diameter of the elastic pad 32, so that the blocking member 3 cannot enter the slurry making cavity 102 through the slurry outlet 24 under normal conditions, and when the blocking member 3 is subjected to a pressing force, for example, when a user loses the blocking member 3 by means of a tool, the elastic pad 32 deforms so that the blocking member 3 can enter the slurry making cavity through the slurry outlet 24, thereby facilitating replacement and cleaning maintenance of the blocking member 3.

The top wall of the rotary cavity 21 does not exceed the top end of the slurry outlet 24 in the height direction, that is, the top wall of the rotary cavity 21 is formed by extending the top end of the slurry outlet 24 transversely outwards, or the top wall of the rotary cavity 21 is gradually reduced outwards from the slurry outlet. Therefore, slurry can be completely filled in the rotary cavity after flowing to the rotary cavity from the slurry outlet, a cavity with air cannot be formed above the rotary cavity, the effect of crushing processing is guaranteed, and sanitary dead angles are avoided. Meanwhile, the crushing blade 103 at least partially overlaps with the pulp outlet 24 and the rotary chamber 21 in the axial direction. Preferably, the crushing blades 103 have at least a part of the blade revolution path in the axial direction of the pulp outlet 24. Therefore, the crushing cutter 103 can directly drive the slurry to flow into the rotary cavity from the slurry outlet in the transverse direction in the crushing process, and the slurry in the rotary cavity is taken away, so that the crushing effect is enhanced.

When the stop member 3 is in the closed position of the closing orifice 23, it is preferred that the stop member 3 is at least partially located above the bottom wall of the pulping chamber 102, i.e. when in the closed position the stop member 3 is at least partially located within the turning chamber 21. At this time, the pulping chamber 102 and the rotary chamber 21 form a chamber body commonly used for crushing, wherein the pulping chamber 102 forms a large chamber body, and the rotary chamber 21 forms a small chamber body. Preferably, the slurry outlet 24 connecting the pulping chamber 102 and the rotary chamber 21 and the inner wall of the rotary chamber 21 form an included angle a which is more than or equal to 30 degrees. If the contained angle sets up the undersize, on the one hand for the thick liquid is difficult to make the thick liquid and revolves the chamber between gyration chamber, and on the other hand also makes the distance increase between system thick liquid chamber and the gyration chamber, and then makes food preparation machine self's size increase, causes the space extravagant.

When the stop member 3 is in the closed position, the part of the chamber 22 above said stop member 3 forms part of a small space into which particulate material, such as incompletely comminuted soybeans, can enter during the comminution process. At the moment, as shown in fig. 4 and 5, the fluid between the rotary cavity and the pulping cavity circulates in the direction of an arrow, the pulping cavity in the large space drives the fluid in the rotary cavity in the small space to flow, and a first-stage low-pressure area is formed at the pulp outlet according to the bernoulli principle, so that the fluid in the rotary cavity has a pressure trend of returning to the pulping cavity, and the pulp in the rotary cavity is accelerated to flow back to the pulping cavity to participate in crushing; similarly, the fluid in the rotary cavity rapidly flows and rotates above the contraction cavity, and according to the Bernoulli principle, a second-stage low-pressure area is formed in a small space formed by the contraction cavity and the stopping piece, so that the slurry and the materials in the area can flow back to the rotary cavity upwards and flow back to the pulping cavity to participate in crushing, and the materials are prevented from remaining in the contraction cavity to influence normal crushing. On one hand, the stopping piece falls into the shrinkage cavity, the self space of the cavity is small, and materials in the shrinkage cavity are easy to be taken away; on the other hand, the fluid in the rotary cavity is easier to form annular backflow around the central area of the stopping piece.

The driving part 4 comprises a driving part, an executing part and a guiding part, the driving part comprises a driving motor 41, the guiding part comprises a driving screw rod 42 and a movable threaded sleeve 43, and the executing part comprises a permanent magnet 44. The driving motor 41 is arranged outside the slurry discharging channel 2, the driving screw 42 is connected with the driving motor 41 and rotates under the driving action of the driving motor 41, and the driving screw 42 extends axially along the outer walls of the rotary cavity 21 and the contraction cavity 22 to form a guide part which has a guide effect on the movable threaded sleeve 43 and the permanent magnet 44. The movable threaded sleeve 43 is sleeved outside the driving screw 42, a plurality of threads, preferably two threads, are arranged outside the driving screw 42, and the movable threaded sleeve 43 is provided with threads matched with the movable threaded sleeve. The multi-thread is arranged, and the thread pitch of the thread is increased, so that the moving speed of the movable threaded sleeve 43 is increased, the permanent magnet 44 can be driven to move rapidly, and finally the stopping piece 3 is driven to switch between the closed position and the non-closed position rapidly.

The closing ball 31 is provided as a magnetically attractable soft magnet, and the actuator for the closing ball 31 is provided as a permanent magnet 44. The closed ball 31 of the soft magnet can be attracted by the permanent magnet but can not be permanently magnetized, and when the action of the permanent magnet 44 is disappeared, the closed ball 31 can rapidly lose magnetism. Set up like this, guaranteed that the piece of preventing can be adsorbed by the permanent magnet and remove to specific position, simultaneously, the piece of preventing can not be in fixed direction because self takes magnetism, like this, when the piece of preventing switches between different positions, perhaps when receiving the impact of thick liquid, can change different directions, guaranteed the sealed effect of piece of preventing with accommodation space promptly, still in the cleaning process, guarantee that each face of piece of preventing all can be washd, avoid the health dead angle.

The driving screw 42 rotates to drive the movable threaded sleeve 43 to move axially, and further drive the stopping member to move in the accommodating space through the permanent magnet 44, when the movable threaded sleeve 43 and the permanent magnet 44 drive the stopping member to move to the closed position, the stroke of the movable threaded rod 43 and the permanent magnet 44 is larger than the movable stroke of the stopping member 3, that is, when the stopping member 3 contacts the closed opening 23 to reach the closed position, the movable threaded rod 43 and the permanent magnet 44 can continue to move forward to exceed the stopping member 3. As shown in FIG. 4, the permanent magnet 44 and the stopper 3 have a stroke difference L1, L1 is 3mm or more and 30mm or less. Set up stroke difference L1, when the prevention piece reachs closed position, the permanent magnet still has the magnetic pull to the prevention piece outside the stroke of prevention piece, and this pulling force superposes with the gravity of prevention piece itself, can strengthen the pressure between prevention piece and the accommodation space inner wall, and then strengthens the sealed effect of prevention piece, prevents that the sealing of prevention piece is inefficacy, especially when thick material is expected to the thick liquid, perhaps, only relies on the gravity of prevention piece, is difficult in guaranteeing sealed effect, sets up the stroke difference, can continuously apply extra effort, guarantees that the prevention piece is quick, the efficient reachs closed position. If the stroke difference L1 is set too small, the decomposing force of the stopper in the sealing direction is too small when the permanent magnet reaches the end, and the sealing effect cannot be well achieved; on the other hand, if the stroke difference L1 is set too large, the magnetic force of the permanent magnet against the stopper decreases, and the reinforcing effect cannot be achieved well. Preferably, the permanent magnet 44 is a cylindrical magnet, and the stopping member is adsorbed outside the accommodating space, so that more stopping members can move along the inner wall of the accommodating space in the moving process, and the spherical stopping member is arranged, so that the stopping member can roll between the closed position and the non-closed position, and the movement efficiency is improved. The permanent magnet is arranged to drive the stopping piece, on one hand, the permanent magnet can continuously act on the stopping piece, and the stopping piece can be acted by the acting force of the permanent magnet when in a closed position or a non-closed position, so that the problems of poor reliability and low state switching speed when only relying on magnetism in the closed position or the non-closed position are avoided; on the other hand, compared with the electromagnet, the permanent magnet has smaller size to meet the requirement, so that the space required by the food processor can be reduced, and the volume of the food processor is reduced; simultaneously, if the electro-magnet needs to continuously act on the stopping piece, need last circular telegram, can increase the consumption of electro-magnet, the electro-magnet uses still can generate heat for a long time, influences food preparation machine's normal function.

Set up accommodation space and supply to block the piece activity, and the driving piece externally blocks the piece with magnetic drive, and the driving piece can not directly set up in arranging the thick liquid passageway, receives the influence of thick liquid little, and the operational environment requirement to driving piece itself is low, and low-cost driving piece can satisfy the requirement, and the volume of driving piece self also need not to set up too greatly simultaneously. The stopping piece is driven by magnetism, can be controlled in a closed state and a non-closed state, can be quickly, efficiently and stably positioned in a closed position, and can be prevented from losing the closing function of the stopping piece; and when the stopping piece is in the non-closed state, the driving piece can control the stopping piece to be far away from the normal slurry discharging path of the slurry discharging channel, so that the slurry discharging channel can be opened to the maximum extent, and the slurry is discharged quickly. Moreover, when the stopping piece is in a closed state and the accommodating space is communicated with the pulping cavity, the accommodating space can also play a pulping cycle together with the pulping cavity, so that the common turbulence is played, the crushing performance is improved, and the space waste of the accommodating space is avoided. And the stopping piece relies on driving piece magnetic drive, requires greatly reduced to the space setting of stopping piece, and then accommodation space's position setting also can optimize the adjustment according to actual demand.

It can be understood that the contraction cavity has a truncated cone-shaped contraction section, and the stop member is a truncated cone matched with the contraction cavity.

It is understood that the driving member has a driving portion rotatably disposed, and the driving portion is rotatably movably disposed to drive the stopping member to move in the accommodating space to close the slurry discharge passage.

The driving part 4 comprises a driving part, an executing part and a guiding part, the driving part comprises a driving motor 41, the guiding part comprises a driving screw rod 42 and a movable threaded sleeve 43, and the executing part comprises a permanent magnet 44. The permanent magnet 44 is arranged in a cylindrical ring shape and sleeved outside the accommodating space, so that the stopping member can exert driving force on the stopping member to the maximum extent in the central magnetic field of the permanent magnet.

It is understood that, as shown in fig. 10, the permanent magnet may also be provided as a plurality of magnets sleeved outside the accommodating space.

Example three.

When the stopper 3 is moved to the second closing port 62, the slurry discharge passage may be partially closed or completely closed to form a second closed position.

According to the processing demands of difference, guarantee to prevent that the piece can totally seal arrange the thick liquid passageway, and when perhaps throwing the material to the slurrying intracavity under non-fluid processing condition, when to the material washing state, probably need not totally seal arrange the thick liquid passageway, for example when throwing the material big material, only need partially seal can, the bottom is ventilative simultaneously can make things convenient for the gas outgoing in the space, when the material is put in the back, can control again and prevent that the piece reaches the closed position. Or when carrying out material dry grinding and processing, the control prevents that a part seals row's thick liquid passageway, and the preformed gap can be through satisfying the material of required size, for example satisfy the rice flour of fineness, like this, the material that has processed, can be timely arrange the thick liquid passageway discharge through, avoid lasting in smashing the intracavity by the excessive processing, still can promote the machining efficiency who smashes other materials of intracavity.
