Description

Technical Field

[0001] The invention belongs to the field of food processing, and in particular relates to a household food processing machine with full-automatic pulping, discharging and cleaning functions. Background Art

[0002] Existing food processing machines that can realize automatic water intake for pulping, pulp discharge, and automatic cleaning and wastewater discharge generally include a body with a motor and a pulping chamber with a crushing space. The body is provided with a water supply component for supplying water to the pulping chamber, a crushing piece is provided in the pulping chamber, the pulping chamber is provided with a pulp outlet, and the body is also provided with a pulp discharge component connected to the pulp outlet. The pulp discharge component can guide the processed slurry into a pulp receiving component, such as a pulp receiving cup, and can also guide the wastewater after cleaning into a wastewater component, such as a wastewater cup.

[0003] In an existing technical solution, a slurry discharge valve is provided in the slurry discharge assembly, and a rotatable valve core is provided in the slurry discharge valve. The valve core can rotate in the slurry discharge valve to open or close the slurry discharge assembly to achieve the control function. However, in this solution, there is an internal space in the valve core body. When it is closed, the slurry or wastewater remaining in the valve core is at risk of deterioration, causing bacteria to grow and affecting the normal use of the user. At the same time, the slurry discharge valve and the valve core need to occupy the slurry discharge space, and the slurry discharge space only plays a role in slurry discharge during the working process, resulting in a decrease in the effective utilization rate of the machine and a decrease in user experience satisfaction.

[0004] There is another control scheme in which an electromagnet is used to drive a magnetic ball to move in a fluid pipeline. When the electromagnet is powered off, the magnetic ball falls into the small-diameter section of the pipeline by gravity, closing the small-diameter section to close the transmission pipeline. When the magnet is powered on, the electromagnet absorbs the magnetic ball to open the small-diameter section to open the transmission pipeline, so that the fluid can pass through the pipeline normally. However, in such a scheme, the magnetic ball used to control the opening or closing of the pipeline is greatly affected by the outside, and can usually only be used for water or fluids close to water, and the fluid cannot be too large. If the density or viscosity of the fluid is large, the ball is greatly affected by the fluid during the opening or closing process, and the action is slow, and the pipeline cannot be opened or closed in time, affecting the normal use of the valve; especially when there is material in the fluid, such as the residual beans when processing soy milk, it will be stuck between the ball and the pipeline, so that the ball cannot close the pipeline normally and loses the corresponding function. The existing control scheme limits the positional relationship between the components. The small-diameter can only be set below the magnetic ball to ensure that it will fall into the small-diameter section to close the pipeline under the action of gravity, which requires that the entire slurry discharge channel can only be set in the vertical direction. For the food processing machine product involved in this application, the function of crushing processing must be met first, and the discharge pipe arranged in the vertical direction will seriously affect the natural crushing function of the product, especially the material falling on the small diameter section in the vertical direction, which may not be crushed normally, and greatly reduce the processing effect of the food processing machine. In addition, the discharge channel arranged vertically increases the height of the product; at the same time, the effective utilization rate of space is reduced. Summary of the invention

[0005] The purpose of the present invention is to provide a slurry discharge assembly with stable and reliable operation, so as to solve the technical problems of poor reliability, large installation space limitation and low space utilization of existing solutions.

[0006] In order to solve the above technical problems, the present invention provides a food processing machine with reliable control, including a machine body and a water supply component, a crushing component and a pulping component arranged on the machine body, the crushing component including a pulping chamber and a crushing member arranged in the pulping chamber, the water supply component provides a water source to the pulping chamber, the pulping chamber is provided with a pulping outlet, the pulping assembly is connected to the pulping outlet and guides the pulp out of the pulping chamber, wherein the pulping assembly includes a pulping channel, a blocking member and a driving member, the pulping channel has an accommodating space, the blocking member can move in the accommodating space to close the pulping channel, and the driving member is arranged outside the pulping channel to magnetically drive the blocking member.

[0007] Preferably, the accommodating space is provided with a closed opening, the blocking member is arranged between the slurry outlet and the closed opening, and the blocking member has a closed position located at the closed opening to close the slurry discharge channel.

[0008] Preferably, the accommodating space is provided with a limiting opening, and the limiting opening is located between the slurry outlet and the blocking member, and the blocking member can also be moved to the limiting opening to at least partially cover the limiting opening.

[0009] Preferably, the blocking member safely closes the limiting opening to form a second closed position.

[0010] Preferably, when the blocking member is located at the closed position, the accommodating space forms a reflux chamber connected to the pulping chamber, and the slurry flows between the pulping chamber and the reflux chamber to participate in the circulation.

[0011] Preferably, the reflux chamber includes a rotation chamber and a contraction chamber, the rotation chamber is connected to the slurry outlet and is extended laterally, the contraction chamber is arranged below the rotation chamber and has a contraction section with a smaller diameter, and the blocking member can be moved from the rotation chamber to the contraction chamber to fit with the inner wall of the contraction chamber to close the slurry discharge channel.

[0012] Preferably, the accommodating space is provided with a closed opening, the blocking member is arranged downstream of the closed opening, and the blocking member has a closed position that moves toward the upstream side to the closed opening to close the slurry discharge channel.

[0013] Preferably, an elastic sealing member is further provided between the accommodating space and the blocking member.

[0014] Preferably, the driving member includes an actuator that magnetically drives the blocking member and a driving member that drives the actuator, and the driving member drives the actuator to move along the outside of the slurry discharge channel and drives the blocking member to open or close the slurry discharge channel.

[0015] Preferably, the driving member also includes a guide portion extending axially, and the driving portion drives the actuator to move axially along the guide portion. The maximum stroke of the actuator moving along the guide portion in the closing direction is greater than the maximum stroke of the blocking member moving in the closing direction, so that the actuator has a movement stroke after the blocking member reaches the closing position.

[0016] After adopting the above technical solution, the present invention has the following advantages:

[0017] 1. The present invention provides a pulp discharge channel, a blocking member and a driving member in a pulp discharge assembly, wherein a storage space is provided for the pulp discharge channel, and the blocking member moves in the storage space to close the pulp discharge channel. Accordingly, the driving member is provided outside the pulp discharge channel to magnetically drive the blocking member to move in the storage space, so that the blocking member moves to a closed position or leaves a closed position to open the pulp discharge channel, and the slurry in the pulping chamber can flow out through the pulp discharge channel. By closing or opening the pulp discharge channel by moving the blocking member in the storage space, the control assembly does not need to be too large in size, which greatly reduces the space occupied by the valve assembly of the food processing machine and improves the space utilization rate of the food processing machine. The storage space is provided for the blocking member to move, and the driving member drives the blocking member magnetically on the outside. The driving member will not be directly provided in the pulp discharge channel, and will be less affected by the slurry. The working environment requirements for the driving member itself are low, and a low-cost driving member can meet the requirements. At the same time, the volume of the driving member itself does not need to be set too large. By relying on magnetic drive, the blocking member can be controlled in both the closed state and the unclosed state, which can ensure that the blocking member is in the closed position quickly, efficiently and stably, and prevent the blocking member from failing in its closing function. At the same time, when the blocking member is in the closed position, the driving member can also apply a reinforcing force to the blocking member to strengthen the force between the blocking member and the accommodating space to further ensure the closing effect; and when the blocking member is in the unclosed state, the driving member can control the blocking member to be away from the normal slurry discharge path of the slurry discharge channel, ensuring that the slurry discharge channel can be in the open state to the greatest extent and discharge slurry quickly. Furthermore, when the blocking member is in the closed state and the accommodating space is connected to the pulping chamber, the accommodating space can also play a pulping cycle together with the pulping chamber, play a role in common turbulence to improve the crushing performance and avoid space waste of the accommodating space. The blocking member is driven by the magnetic drive of the driving member, which greatly reduces the space setting requirements for the blocking member, and the position setting of the accommodating space can also be optimized and adjusted according to actual needs.

[0018] 2. The blocking member is arranged between the pulp outlet and the closed port. When the blocking member needs to reach the closed position, it moves toward the closed port along the natural flow direction of the pulp, which can reduce the resistance of the blocking member to move toward the closed position. The blocking member can quickly reach the closed position. When the pulp discharge channel needs to be opened, the driving member drives the blocking member to leave the closed position. Furthermore, when the blocking member is in the closed position, the accommodation space is connected to the pulping cavity through the pulp outlet, and can participate in the cooking process of the pulping cavity, improve the processing environment, and avoid space waste when the accommodation space is closed.

[0019] 3. A limit opening is further provided, and the blocking member can be moved to the limit opening and at least partially block the limit opening, so that the blocking member has the functions of completely closing the pulp discharge channel and partially closing the pulp discharge channel at the same time. For food processing machines, different cooking ingredients require different processing conditions. For fluid cooking ingredients, such as soy milk, the blocking member can completely close the pulp discharge channel to prevent the pulp from flowing out of the pulp discharge channel during normal operation; and for processing dry-ground materials, such as dry-grinding rice to process rice noodles, the pulp discharge channel can be completely closed, and when the processing is completed, the material is directly taken out of the pulping chamber or discharged through the pulp discharge channel. The blocking member can also be moved to the limit opening and partially block the limit opening at the same time, so that the limit opening can pass small materials such as crushed rice noodles, while materials of normal size are blocked by the blocking member and cannot be discharged from the pulping chamber normally through the limit opening. In this way, the crushed materials are discharged synchronously while the materials are being crushed, which improves the efficiency of crushing in the pulping chamber and can also prevent the crushed materials from being over-processed after being crushed for a long time in the pulping chamber. Moreover, even when processing fluid food materials, such as processing soy milk, the blocking member can be moved to the closed port first, which can be completely closed or partially closed, only ensuring that the second material can enter the pulping chamber normally, and will not enter the accommodating space during the feeding stage. When the food materials need to be pre-cleaned, the blocking member partially blocks the limiting port, the material will not leak out from the limiting port, and the waste water of the cleaning material can be discharged synchronously, improving the cleaning effect and speed, avoiding opening the closed port after cleaning the material, so that there are still dirt remaining in the pulping chamber after cleaning. Of course, the blocking member can also completely close the closed port at the limiting port to form a second closed position, on the one hand, preventing the accommodating space from communicating with the pulping chamber, ensuring the integrity of the pulping chamber; on the other hand, the closed state at different positions is particularly suitable for the self-cleaning process of the food processing machine, wherein the blocking member switches between different closed positions, which can facilitate the cleaning of the pulping chamber, and can also clean the pulping components, especially the accommodating space and the blocking member itself when switching between different positions, without sanitary dead corners, ensuring the safety and sanitation of the food processing machine.

[0020] 4. The accommodating space and the pulping chamber form a reflux chamber. During the processing, the pulp flows between the pulping chamber and the reflux chamber to participate in the circulation, avoiding the waste of the accommodating space, and can also increase the pulping capacity of the pulping chamber and improve the space utilization rate of the food processor. At the same time, during the processing, the reflux chamber participates in the turbulence processing of the pulping chamber from the outside of the pulping chamber, which can change the liquid flow mode of a single pulping chamber, thereby improving the crushing effect of the pulping chamber, so that the food processor can complete the cooking process faster.

[0021] 5. Set up a rotary chamber and a contraction chamber. The rotary chamber is extended in the transverse direction, and the contraction chamber is located below the rotary chamber. In this way, the transversely arranged rotary chamber fully refluxes with the pulping chamber in the transverse direction and then participates in the crushing process. Since there is no height difference between the rotary chamber and the pulping chamber in the transverse direction, the slurry will not have difficulty in reflux due to the height difference when flowing between the pulping chamber and the rotary chamber. Generally speaking, there is an obvious difference in volume share between the pulping chamber and the rotary chamber. When the slurry circulates in the pulping chamber, the pulp flowing through the pulp outlet drives the slurry in the pulping channel to flow back to the pulping chamber, so that a pressure difference is formed between the rotary chamber and the pulping chamber, accelerating the slurry in the rotary chamber to flow back to the pulping chamber. The contraction chamber is arranged below the rotary chamber. When it is in a closed state, the blocking member is more located in the contraction chamber, which can occupy a larger space in the contraction chamber. The amount of slurry flowing into the contraction chamber is not much, which will not affect the crushing pulping. At the same time, since the blocking member occupies most of the space in the contraction chamber, the contraction chamber has a smaller volume ratio than the rotary chamber. During the reflux process between the rotary chamber and the pulping chamber, the slurry flows rapidly above the contraction chamber, driving the contraction chamber to form a pressure difference compared to the rotary chamber. The slurry remaining in the contraction chamber can be taken away from the contraction chamber, and then participate in the processing of the rotary chamber and the pulping chamber, without affecting the normal cooking processing of the food processor.

[0022] 6. The blocking member is located downstream of the closed port, and the blocking member moves upstream to close the closed port. For a food processing machine, the blocking member is usually always in a closed state during the processing process. Therefore, when the blocking member is not in working state, the movement of the blocking member will not be affected by the material. When the blocking member needs to open the closed port to conduct the pulp discharge channel, the movement of the blocking member is the same as the flow direction of the slurry, and can quickly move to the open position to conduct the pulp discharge channel, thereby increasing the pulp discharge speed. When the pulp discharge is completed and in the cleaning process, the same blocking member can quickly move to open to achieve the function of discharging waste water. At the same time, the accommodation space is set at the rear side of the closed port, and the requirements for the accommodation space itself are not high. It is only used to accommodate the blocking member, and the space occupied is small. It does not affect the normal processing of the pulping chamber, thereby improving the space utilization rate of the food processing machine. At the same time, the blocking member is located downstream of the closed port. When the blocking member opens the pulp discharge channel, the slurry will first pass through the blocking member and then be discharged from the pulp discharge channel, thereby avoiding the impact of the slurry when it is directly discharged from the pulp discharge channel, and the slurry flows out more evenly and smoothly.

[0023] 7. An elastic seal is provided between the accommodating space and the blocking member. When the blocking member contacts the accommodating space and performs a sealing function, the elastic seal can be squeezed to strengthen the sealing effect, thereby preventing the sealing function of the blocking member from failing. At the same time, the elastic seal reduces the size matching requirements between the blocking member and the accommodating space, reduces the size requirements of the blocking member and the accommodating space, and reduces the production cost of the food processing machine.

[0024] 8. An execution unit and a driving unit are further provided. The execution unit can continuously act on the blocking member so that the blocking member can reach a closed or open working state of the slurry discharge channel under a controlled state. A driving unit is provided to drive the blocking member through the execution unit. When the blocking member switches between a closed state and an open state, it can rely on the driving unit to switch quickly, thereby avoiding relying only on gravity when there is no external driving force, and the switching time and switching state cannot be guaranteed.

[0025] 9. A guide part is further provided to limit the moving path of the actuator, so that the actuator can run on a more reliable stroke, ensuring the stroke accuracy and reliable speed of the actuator. It can even be said that the blocking member can reach a preset position through the driving part and the guide part. For example, in the process of pulping, it is necessary to control the flow rate of the slurry, and the blocking member can be controlled to reach a preset position between a closed state and a fully open state; or in the process of self-cleaning of the food processor, the blocking member is controlled to partially open the pulping channel, so that the waste water generated during the cleaning process can be discharged from the pulping chamber through the pulping channel, but due to the blocking effect of the blocking member, the pulping channel will not be fully opened, reducing the waste of water caused by complete discharge. Furthermore, a maximum stroke of the actuator moving along the guide portion in the closing direction is set to be greater than the maximum stroke of the blocking member moving in the closing direction, that is, when the blocking member reaches the closing position in contact with the accommodating space, the actuator still has a stroke to move in the closing direction. In this way, when the actuator reaches the final end position, a magnetic pulling force in the closing direction is continuously applied to the blocking member, so that the squeezing force between the blocking member and the inner wall of the accommodating space is increased, thereby strengthening the sealing effect between the blocking member and the inner wall of the accommodating space. Compared with the prior art that can only rely on the weight or size of the blocking member itself, the sealing effect of the food processor can be guaranteed to a greater extent.

[0045] The food processing machine of the present invention is reliable in operation. Figure 1-11As shown, it includes a body and a water supply component, a crushing component and a pulping component arranged on the body. Preferably, the water supply component includes a water tank, a water pump, and a water supply pipeline. The crushing component includes a pulping chamber and a crushing piece arranged in the pulping chamber. The water supply component provides water to the pulping chamber, which can be used for processing food or for cleaning the crushing component after processing. The pulping chamber is provided with a pulping outlet, and the pulping component is connected to the pulping outlet. After the food processor completes the cooking process of the food, the food is discharged through the pulping outlet through the pulping component, and the cooked slurry is received by a pulp receiving container, such as a pulp receiving cup arranged outside the cup body; further, when the food processor is cleaned after processing, the waste water after cleaning is also discharged by the pulping component and received by the waste water container. In order to optimize the existing pulp discharge assembly and avoid the pulp discharge assembly occupying too much space of the food processing machine, and at the same time, the pulp discharge assembly can efficiently and quickly open or close the pulp discharge channel, the pulp discharge assembly adopts the following scheme: the pulp discharge assembly includes a pulp discharge channel, a blocking member and a driving member, one end of the pulp discharge channel is connected to the pulp outlet, and the other end guides the fluid to the pulp receiving container or the wastewater container, and the pulp discharge channel is further provided with a accommodating space, and the blocking member can be movably arranged in the accommodating space to move in the accommodating space to close or open the pulp discharge channel, and the driving member is arranged outside the pulp discharge channel to magnetically drive the blocking member to move in the accommodating space, so that the driving member does not need to be arranged in the pulp discharge channel, and will not contact with the fluid during the pulp discharge process, so as to avoid affecting the normal flow of the fluid and ensure the efficient operation of the pulp discharge assembly to the greatest extent. The blocking member moves in the accommodating space and closes the pulp discharge channel. When it moves to the closed position, the pulp discharge channel can be completely closed, and when the blocking member is in other controlled positions, it can also control the flow rate of the fluid in the pulp discharge channel. Only the accommodating space and the corresponding blocking member are provided to control the pulp discharge passage, and the space requirement of the control assembly is greatly reduced, and the space used by the food processor for installing and controlling the pulp discharge assembly is reduced, so that the space utilization rate of the food processor itself is greatly improved. When the blocking member is located between the pulp outlet and the closed opening of the accommodating space, so that the blocking member contacts the accommodating space at the downstream side of the accommodating space and closes the pulp discharge passage, the accommodating space can be connected with the pulping chamber through the pulp outlet, and then participate in the cooking process in the pulping chamber, thereby avoiding the waste of space caused by the accommodating space being only used for pulp discharge.When the closing port is located between the blocking member and the slurry outlet, that is, the blocking member moves upstream of the accommodating space to close the slurry discharge channel, at this time, the accommodating space only needs to isolate the driving member and the blocking member, and at the same time connect the closing port and the slurry discharge channel. The space requirement is not high, and there is no need to set a larger volume to meet the demand, and it will not occupy too much space in the food processing machine. At the same time, the accommodating space is still connected to the outside through the slurry discharge channel when it is in a closed state, and is connected to the slurry making chamber and the external space through the slurry outlet when it is not in a closed state. There is no sanitary dead corner, and the slurry can be prevented from remaining in the accommodating space.

[0046] Embodiment 1.

[0047] As a first embodiment of a food processing machine with reliable control according to the present invention, Figure 1-5 As shown, the food processor includes a body and a water supply component, a crushing component, a pulp discharge component and a pulp receiving component arranged on the body, wherein a motor 105 is arranged in the body, and the water supply component includes a water tank 101, a water pump and a water supply pipeline, and the water pump draws water from the water tank 101 and supplies the water to the crushing component through the water supply pipeline. The crushing component includes a pulping chamber 102 and a crushing knife 103, and the pulping chamber 102 is provided with a water inlet and a pulp outlet 24, wherein the water inlet is connected to the water supply pipeline, and the pulp outlet 24 is connected to the pulp discharge component, and the crushing knife 103 is driven by the motor 105 to crush the food placed in the pulping chamber 102, and at the same time, it drives the fluid in the pulping chamber 102 to flow during cleaning, so as to realize the cleaning of the pulping chamber 102 and the corresponding connecting space. The slurry discharge assembly connects the slurry making chamber and the slurry receiving assembly so as to guide the slurry into the slurry receiving assembly after the grinding assembly completes the processing. The slurry receiving assembly includes a slurry receiving cup 104 and a waste water box, wherein the slurry receiving cup 104 is used to store the processed food materials, and the waste water box is used to store the waste water for cleaning the food processor. Of course, it can be understood that the slurry receiving assembly is only for the convenience of the user to store and store the slurry and waste water. They can be different containers, or the same container can be used in different stages. The container can be attached to the food processor product, or it can be directly provided by the user. For example, the user directly uses a personal water cup to receive the processed slurry, and then directly discharges the waste water into the sewer through the conduit.

[0048] The slurry discharge assembly includes a slurry discharge channel 2, a blocking member 3 and a driving member 4. A receiving space is provided in the slurry discharge channel. The blocking member 3 is located in the receiving space and can move in the receiving space under the driving action of the driving member 4. The receiving space is provided with a closed opening 23. The blocking member 3 closes the slurry discharge channel 2 when it moves to the closed opening 23. Preferably, the blocking member 3 is located between the slurry outlet 24 and the closed opening 23. Of course, it should be noted that located between the slurry outlet 24 and the closed port 23 means located between the slurry outlet and the closed port in the flow direction of the fluid, that is, when the fluid flows out from the slurry outlet, it will first pass through the blocking member and then flow through the closed port. Similarly, the flow of the fluid does not refer to the shortest distance, but to the cross-section of the space through which the fluid can flow from the slurry outlet to the closed port. For example, a placement cavity is provided between the slurry outlet and the closed port, and the blocking member can be moved into the placement cavity in a non-closed state, while the fluid or most of the fluid flows completely through the outside of the placement cavity. At this time, the blocking member also belongs to the category between the slurry outlet and the closed port.

[0049] like Figure 2-5 As shown, when the blocking member 3 is in the closed position, the accommodation space between the pulp outlet and the blocking member 3 is connected to the pulping chamber 102 through the pulp outlet 24 to form a reflux chamber. During the operation of the crushing assembly, the liquid in the reflux chamber flows with the liquid in the pulping chamber 102 through the pulp outlet 24 to participate in the cyclic crushing pulping. Preferably, the reflux chamber includes a rotary chamber 21 and a contraction chamber 22. The rotary chamber 21 is connected to the pulp outlet 24. The pulp outlet 24 is arranged at the bottom of the side wall of the pulping chamber 102. The rotary chamber 21 extends outward in the transverse direction of the food processor to communicate with the pulping chamber 102 in the transverse direction. The contraction chamber 22 is arranged below the rotary chamber 21, and the contraction chamber 22 has a contraction section with a smaller diameter. The closed opening 23 is arranged in the contraction section. In this way, the blocking member 3 can retract the rotary chamber 21 and move to the contraction chamber 22 and contact the closure 23 in the contraction section to close the pulp discharge channel.

[0050] Preferably, the blocking member 3 is spherical, including a closing ball 31 and an elastic pad 32 disposed outside the closing ball 31, wherein the elastic pad 32 completely covers the closing ball 31. The contraction cavity 22 is truncated cone-shaped, wherein the diameter of the end communicating with the rotary cavity 21 is larger than the blocking member 3, and the diameter of the end with the closing port 23 is smaller than the blocking member 3, so that the blocking member 3 can fit with the inner wall of the contraction cavity 22 when moving into the contraction cavity 22 to close the slurry discharge channel. The elastic pad 32 can be squeezed and deformed during closing to enhance the sealing effect.

[0051] The cross-sections of the rotary chamber 21 and the contraction chamber 22 are in the shape of "7", so that the rotary chamber 21 forms a placement chamber 26 at one end of the slurry outlet 24, that is, the placement chamber 26 is formed at the corner of the "7" shape. The blocking member 3 can be moved into the placement chamber 26 under the action of the driving member 4. At this time, the slurry is discharged from the slurry outlet, flows under the blocking member 3 and is finally discharged from the slurry outlet 25. This arrangement can ensure that the slurry discharge channel has the largest cross-sectional area when it is in the open state. When the blocking member 3 is located in the placement chamber 26, the equivalent diameter of the flow section between the slurry discharge channel and the blocking member is D1, 4mm≤D1≤50mm. If D1 is set too small, the maximum slurry discharge flow rate of the entire slurry discharge channel during the slurry discharge process is too small, and the slurry discharge speed is too slow, which affects the user experience; if D1 is set too large, although the slurry discharge speed is increased, the volume of the slurry discharge component will increase too much, resulting in a waste of space. Preferably, the bottom of the placement cavity 26 is further provided with a protrusion 261, or the placement cavity 26 is expanded outwardly compared to the shrinkage cavity 22 to form the protrusion 261 at the connection, and the protrusion 261 can be used to support the blocking member 3 when the blocking member 3 moves to the placement cavity 26, so as to prevent the blocking member 3 from easily detaching from the placement cavity 26 and falling into the shrinkage cavity 22, especially when the blocking member 3 is impacted by slurry, the protrusion 261 makes the blocking member 3 reliably located in the placement cavity 26. Preferably, the placement cavity 26 is a spherical surface corresponding to the blocking member 3, and the diameter of the placement cavity 26 is slightly larger than the diameter of the blocking member 3, wherein the placement cavity 26 is 2mm-5mm larger than the diameter of the blocking member 3. If the diameter difference is too small, when there is a size error between the blocking ball and the placement cavity, the blocking ball may not be able to fully enter the placement cavity; if the diameter difference is too large, the gap between the placement cavity and the blocking ball is too large, and the placement effect cannot be well achieved.

[0052] The diameter of the pulp outlet 24 is smaller than the diameter of the blocking member 3, so that the blocking member 3 does not enter the pulping chamber 102 from the pulp outlet 24 during normal operation, preventing the blocking member 3 from interfering with the normal crushing of the crushing knife 103. Optionally, the diameter of the pulp outlet 24 is larger than the diameter of the closing ball 31, but smaller than the diameter of the elastic pad 32, so that the blocking member 3 does not enter the pulping chamber 102 from the pulp outlet 24 under normal circumstances, and when the blocking member 3 is subjected to a squeeze force, for example, when the user loses the blocking member 3 with the help of a tool, the elastic pad 32 is deformed so that the blocking member 3 can enter the pulping chamber from the pulp outlet 24, which is convenient for replacement, cleaning and maintenance of the blocking member 3.

[0053] The top wall of the rotary chamber 21 does not exceed the top of the pulp outlet 24 in the height direction, that is, the top wall of the rotary chamber 21 is formed by extending laterally outward from the top of the pulp outlet 24, or the top wall of the rotary chamber 21 is gradually lowered from the pulp outlet outward. In this way, after the slurry flows from the pulp outlet to the rotary chamber, it can completely fill the rotary chamber, and no cavity with air is formed above the rotary chamber, which ensures the effect of the crushing process and avoids the existence of sanitary dead corners. At the same time, the crushing knife 103 at least partially overlaps with the pulp outlet 24 and the rotary chamber 21 in the axial direction. Preferably, the rotation path of at least part of the blade of the crushing knife 103 is within the axial direction of the pulp outlet 24. In this way, during the crushing process, the crushing knife 103 can directly drive the slurry from the pulp outlet into the rotary chamber in the lateral direction, and take away the slurry in the rotary chamber, thereby enhancing the crushing effect.

[0054] When the blocking member 3 is located at the closed position of the closed opening 23, preferably, the blocking member 3 is at least partially located above the bottom wall of the pulping chamber 102, that is, when in the closed position, the blocking member 3 is at least partially located in the rotary chamber 21. At this time, the pulping chamber 102 and the rotary chamber 21 form a cavity used for crushing, wherein the pulping chamber 102 forms a large cavity and the rotary chamber 21 forms a small cavity. Preferably, the pulping outlet 24 connecting the pulping chamber 102 and the rotary chamber 21 and the inner wall of the rotary chamber 21 form an angle a, a≥30°. If the angle is set too small, on the one hand, it makes it more difficult for the slurry to rotate between the pulping chamber and the rotary chamber, and on the other hand, it also increases the distance between the pulping chamber and the rotary chamber, thereby increasing the size of the food processor itself and causing space waste.

[0055] When the blocking member 3 is in the closed position, the portion of the contraction chamber 22 located on the blocking member 3 forms a small space. During the crushing process, particulate materials, such as incompletely crushed soybeans, will enter the small space. Figure 4 , 5As shown, the fluid between the rotary chamber and the pulping chamber circulates in the direction of the arrow, and the large pulping chamber drives the fluid in the small rotary chamber to flow. According to the Bernoulli principle, a first-level low-pressure area is formed at the pulp outlet, so that the fluid in the rotary chamber has a pressure tendency to flow back to the pulping chamber, accelerating the slurry in the rotary chamber to flow back to the pulping chamber to participate in crushing; similarly, the fluid in the rotary chamber flows rapidly above the contraction chamber. According to the Bernoulli principle, a second-level low-pressure area is formed in the small space formed by the contraction chamber and the blocking member, so that the slurry and materials in this area can flow back to the rotary chamber upwards, and then flow back to the pulping chamber to participate in crushing, thereby avoiding the material remaining in the contraction chamber and affecting normal crushing. The blocking member is set to at least partially extend into the rotary chamber. On the one hand, after the blocking member falls into the contraction chamber, there is not much space in the chamber itself, which is easy to take away the material in the contraction chamber; on the other hand, it also makes it easier for the fluid in the rotary chamber to form an annular reflux around the central area of ​​the blocking member.

[0056] The driving member 4 includes a driving part, an execution part and a guide part. The driving part includes a driving motor 41, the guide part includes a driving screw 42 and a movable screw sleeve 43, and the execution part includes a permanent magnet 44. The driving motor 41 is arranged outside the pulp discharge channel 2, the driving screw 42 is connected to the driving motor 41, and rotates under the driving action of the driving motor 41. The driving screw 42 is axially extended along the outer wall of the rotary chamber 21 and the contraction chamber 22 to form a guide part with a guiding effect on the movable screw sleeve 43 and the permanent magnet 44. The movable screw sleeve 43 is sleeved on the outside of the driving screw 42, and the driving screw 42 is provided with a multi-start thread, preferably a two-start thread, and the movable screw sleeve 43 is provided with a thread matched therewith. The multi-start thread is provided, and the pitch of the thread is increased, so that the movement speed of the movable screw sleeve 43 is accelerated, and then the permanent magnet 44 can be driven to move quickly, and finally the blocking member 3 is driven to switch quickly between the closed position and the non-closed position.

[0057] The closing ball 31 is configured as a soft magnet that can be magnetically adsorbed, and the actuator for the closing ball 31 is configured as a permanent magnet 44. The closing ball 31 of a soft magnet can be adsorbed by a permanent magnet, but will not be permanently magnetized. When the effect of the permanent magnet 44 disappears, the closing ball 31 can quickly lose its magnetism. This configuration ensures that the blocking member can be adsorbed by the permanent magnet and moved to a specific position. At the same time, the blocking member will not be in a fixed direction due to its own magnetism. In this way, when the blocking member switches between different positions or is impacted by slurry, it can change different directions, that is, it ensures the sealing effect of the blocking member and the accommodating space. In the cleaning process, it is also ensured that all surfaces of the blocking member can be cleaned to avoid sanitary dead corners.

[0058] The driving screw 42 rotates to drive the movable screw sleeve 43 to move axially, and then drives the blocking member to move in the accommodation space through the permanent magnet 44. When the movable screw sleeve 43 and the permanent magnet 44 drive the blocking member to move to the closed position, the stroke of the movable screw 43 and the permanent magnet 44 is greater than the movable stroke of the blocking member 3, that is, when the blocking member 3 contacts the closed port 23 and reaches the closed position, the movable screw 43 and the permanent magnet 44 can continue to move forward to exceed the blocking member 3. Figure 4 As shown, the permanent magnet 44 and the blocking member 3 have a stroke difference L1, 3mm≤L1≤30mm. The stroke difference L1 is set, when the blocking member reaches the closed position, the permanent magnet still has a magnetic pulling force on the blocking member outside the stroke of the blocking member, and the pulling force is superimposed with the gravity of the blocking member itself, which can strengthen the pressure between the blocking member and the inner wall of the accommodating space, thereby strengthening the sealing effect of the blocking member and preventing the sealing failure of the blocking member, especially when the slurry is a thick material, or it is difficult to ensure the sealing effect by relying solely on the gravity of the blocking member. The stroke difference is set, and additional force can be continuously applied to ensure that the blocking member reaches the closed position quickly and efficiently. If the stroke difference L1 is set too small, when the permanent magnet reaches the end, the decomposition force on the blocking member in the sealing direction is too small, and the sealing effect cannot be achieved well; and if the stroke difference L1 is set too large, the magnetic force of the permanent magnet on the blocking member decreases, and the strengthening effect cannot be achieved well. Preferably, the permanent magnet 44 is a columnar magnet, which adsorbs the blocking member outside the accommodation space, so that the blocking member moves more closely to the inner wall of the accommodation space during movement, and the spherical blocking member can make the blocking member roll between the closed position and the non-closed position, thereby improving the movement efficiency. The permanent magnet is set to drive the blocking member. On the one hand, the permanent magnet can continuously act on the blocking member, and the blocking member can be subjected to the force of the permanent magnet when it is in the closed position or the non-closed position, thereby avoiding poor reliability and slow state switching speed when relying only on magnetism in the closed position or the non-closed position; on the other hand, compared with the electromagnet, the permanent magnet has a smaller size to meet the demand, which can reduce the space required by the food processor and reduce the volume of the food processor itself; at the same time, if the electromagnet needs to continuously act on the blocking member, it needs to be continuously powered on, which will increase the power consumption of the electromagnet, and the electromagnet will also heat up after long-term use, affecting the normal function of the food processor.

[0059] A containing space is provided for the movement of the blocking member, and the driving member drives the blocking member externally by magnetism. The driving member will not be directly provided in the pulp discharge channel, and will be less affected by the slurry. The working environment requirements for the driving member itself are low, and a low-cost driving member can meet the requirements. At the same time, the volume of the driving member itself does not need to be set too large. By relying on magnetic driving of the blocking member, the blocking member can be controlled in both the closed state and the non-closed state, which can ensure that the blocking member is in a closed position quickly, efficiently and stably, and prevent the blocking member from failing in the closing function. At the same time, when the blocking member is in the closed position, the driving member can also apply a strengthening force to the blocking member, strengthen the force between the blocking member and the containing space, to further ensure the closing effect; and when the blocking member is in the non-closed state, the driving member can control the blocking member to be away from the normal pulp discharge path of the pulp discharge channel, to ensure that the pulp discharge channel can be in an open state to the greatest extent, and the pulp can be discharged quickly. Furthermore, when the blocking member is in a closed state, and the containing space is connected to the pulping chamber, the containing space can also play a pulping cycle together with the pulping chamber, play a common turbulence to improve the crushing performance, and avoid space waste of the containing space. The blocking member is driven magnetically by the driving member, so the space requirement for the blocking member is greatly reduced, and the position setting of the accommodating space can also be optimized and adjusted according to actual needs.

[0060] It can be understood that the contraction cavity has a truncated cone-shaped contraction section, and the blocking member is a truncated cone that matches therewith.

[0061] It can be understood that the driving member has a rotatably arranged driving portion, and the driving portion is rotatably arranged to drive the blocking member to move in the accommodating space to close the pulp discharge channel.

[0062] It can be understood that the execution part can be configured as an electromagnet that can absorb the blocking member.

[0063] Embodiment 2.

[0064] As a second embodiment of the food processing machine with reliable control according to the present invention, Figure 6-9 As shown, compared with the first embodiment, the arrangement of the accommodation space and the arrangement of the driving member are further changed in this embodiment.

[0065] The slurry discharge channel includes a accommodating space, which is surrounded by an upper cover body 51 and a lower cover body 52, wherein the upper cover body 51 is connected to the slurry outlet 24, and has a cavity with a diameter that gradually increases. The lower cover body 52 is provided with a closed opening 23 at the bottom, and has a funnel-shaped cavity with a diameter that gradually decreases. When the upper cover body 51 and the lower cover body 52 are surrounded, a cavity shape is formed with small ends from the slurry outlet to the closed opening and a large middle. The blocking member 3 is arranged in the accommodating space and can contact the accommodating space at the closed opening to close the slurry discharge channel.

[0066] The driving member 4 includes a driving part, an execution part and a guide part, wherein the driving part includes a driving motor 41, the guide part includes a driving screw 42 and a movable screw sleeve 43, and the execution part includes a permanent magnet 44. The permanent magnet 44 is arranged in a cylindrical ring shape and is sleeved outside the accommodation space, so that the blocking member can exert a driving force on the blocking member to the greatest extent in the central magnetic field of the permanent magnet.

[0067] Understandable, such as Fig.10 As shown, the permanent magnet may also be configured as a plurality of magnets sleeved outside the accommodation space.

[0068] Embodiment three.

[0069] As a third embodiment of a food processing machine with reliable control according to the present invention, Fig.11 As shown, compared with the first embodiment, the arrangement of the accommodation space and the arrangement of the driving member are further changed in this embodiment.

[0070] like Fig.11 As shown, the slurry discharge channel has a receiving space 6, and the receiving space 6 is provided with a first closed opening 61 and a second closed opening 62. The blocking member 3 is movably arranged in the receiving space 6, and the driving member 4 is arranged outside the receiving space 6 to drive the blocking member 3. The first closed opening 61 is close to one side of the slurry receiving assembly, and the second closed opening 62 is close to one side of the slurry outlet. The blocking member moves between the first closed opening 61 and the second closed opening 62 and can reach the first closed opening 61 or the second closed opening 62 respectively.

[0071] When the blocking member 3 moves to the first closed opening 61, the accommodating space 6 can be completely closed to form a first closed position, thereby closing the slurry discharge passage. When the blocking member 3 moves to the second closed opening 62, the slurry discharge passage can be partially or completely closed to form a second closed position.

[0072] According to different processing requirements, it is ensured that the blocking member can completely close the discharge channel. Under non-fluid processing conditions or when feeding materials into the pulping chamber or when the materials are being cleaned, it may not be necessary to completely close the discharge channel. For example, when feeding large materials, only partial closure is required. At the same time, the bottom ventilation can facilitate the discharge of gas in the space. After the materials are fed, the blocking member can be controlled to reach the closed position. Or when performing dry grinding of materials, the blocking member is controlled to partially close the discharge channel, and the reserved gap can pass materials that meet the required size, such as rice flour that meets the fineness. In this way, the processed materials can be discharged through the discharge channel in a timely manner to avoid continuous over-processing in the grinding chamber, and the processing efficiency of other materials in the grinding chamber can also be improved.

[0073] It can be understood that the accommodating space may only have a closed opening located upstream of the blocking member, and the blocking member, under the driving action of the driving member, moves upstream to close the slurry discharge channel (equivalent to the third embodiment, which only has a completely closed second closed opening).

[0074] It is understandable that the blocking member 3 may partially or completely block the slurry discharge channel at the first closed opening, and completely block the slurry discharge channel at the second closed opening. That is, only one of the first closed opening, the second closed opening and the blocking member needs to be completely closed.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made according to the present invention are covered by the scope of the claims of the present invention and will not be listed one by one here.
