Description

Technical Field

[0001] This invention relates to an assembled waterproof intelligent temperature sensor, a customizable shearing, grinding and stirring soy milk maker and its control system. Background Technology

[0002] In modern intelligent soy milk makers and other food processing equipment, precise temperature control during the soy milk making process is crucial to ensuring the taste, nutrient extraction efficiency, and food safety of soy milk. The soy milk making temperature directly affects protein denaturation, enzyme activity inhibition, and the formation of flavor compounds.

[0003] To achieve precise temperature control, a temperature sensor is usually installed inside the soymilk maker's pulping chamber to collect the temperature of the soymilk in real time and feed the signal back to the device's microcontroller. The microcontroller compares the set temperature with the actual temperature and dynamically adjusts the power of the water heating module integrated in the water supply system, thereby adjusting the temperature of the warm water injected into the pulping chamber, forming a closed-loop temperature control system.

[0004] Due to the harsh environment inside the pulping chamber, the sensor is exposed to high temperature, high pressure, high humidity, and water vapor rich in starch, protein, and other substances that easily form scale. This requires the temperature sensor to have an extremely high level of sealing and waterproofing to prevent liquid infiltration from causing electrical short circuits, signal drift, or component corrosion failure. To facilitate maintenance, calibration, or replacement, the sensor is often designed with an assemblable structure.

[0005] Currently, the waterproofing of assembled sensors in existing technologies mainly relies on a static seal achieved by setting a single O-ring or gasket between the sensor probe and the mounting base. During installation, the seal is achieved by tightening the threads or pressing the flange to compress the sealing ring and generate radial or axial deformation.

[0006] However, when applying axial force, insufficient force will lead to poor sealing, while excessive force may crush the sealing ring or damage the threads. Moreover, this method is a one-way seal, which can usually only prevent external liquids from entering. If a single sealing line fails due to pressure or temperature changes, the waterproof capability is completely lost. Summary of the Invention

[0007] The purpose of this invention is to provide an assembled waterproof intelligent temperature sensor, a customizable shearing, grinding and stirring soy milk maker and its control system, in order to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] An assembled waterproof smart temperature sensor, comprising:

[0010] A sealing tube, and a flexible sealing ring disposed at the end of the sealing tube;

[0011] Also includes:

[0012] The sensor body is inserted into the sealed tube. The sealed tube is provided with a positioning and pushing mechanism connected to the sensor body. A limit plate is connected to the positioning and pushing mechanism, and the positioning and pushing mechanism can lock the position of the sensor body through the limit plate.

[0013] A bidirectional sealing mechanism is provided on the sensor body and cooperates with the limiting plate. The bidirectional sealing mechanism can perform a bidirectional sealing action on the flexible sealing ring when the limiting plate moves.

[0014] As a further embodiment of the present invention: the positioning and pushing mechanism includes a buffer tube disposed on the outer wall of the sealing tube, a movable rod slidably installed inside the buffer tube, the movable rod being fixedly connected to the limiting plate, a limiting ring being disposed on the movable rod to abut against the sealing tube, and a first spring being sleeved on the movable rod, the two ends of the first spring abutting against the buffer tube and the limiting ring respectively.

[0015] As a further embodiment of the present invention: the positioning and pushing mechanism further includes a guide groove formed on the inner wall of the sealing tube, a limiting block is provided on the outer wall of the sensor body to slide and fit with the guide groove, and an arc-shaped groove is formed on the top of the sensor body to abut against the limiting plate.

[0016] As a further embodiment of the present invention: the bidirectional sealing mechanism includes a probe rod disposed at the end of the sensor body, a fixed sealing disc disposed on the probe rod, a movable sealing disc sliding axially on the probe rod, and the fixed sealing disc and the movable sealing disc engaging with the flexible sealing ring;

[0017] It also includes a sliding component and an elastic component disposed on the sensor body.

[0018] As a further embodiment of the present invention: the sliding assembly includes a sliding sleeve disposed on the movable sealing disc and sleeved on the probe rod, the sensor body has symmetrically arranged sliding grooves, a sliding plate is slidably installed in the sliding grooves, and a connecting rod hinged to the sliding sleeve is hinged to the sliding plate.

[0019] As a further embodiment of the present invention: the elastic component includes a guide post disposed in the groove and slidably connected to the sliding plate, a second spring sleeved on the guide post, and the two ends of the second spring abutting against the inner wall of the groove and the sliding plate respectively.

[0020] A customizable shearing, grinding, and blending soy milk maker, comprising:

[0021] A workbench, and a mixing tank set on the workbench;

[0022] A transmission rod is rotatably installed inside the mixing tank, and the transmission rod is equipped with stirring blades and fixed crushing blades;

[0023] A resistance adjustment mechanism is provided on the transmission rod, and a movable crushing blade is connected to the resistance adjustment mechanism. The resistance adjustment mechanism can adjust the resistance between the movable crushing blade and the fixed crushing blade according to the resistance experienced by the movable crushing blade.

[0024] As a further embodiment of the present invention: the resistance adjustment mechanism includes a movable block slidably installed inside the transmission rod, and a third spring is provided inside the transmission rod that abuts against the movable block.

[0025] As a further embodiment of the present invention: the resistance adjustment mechanism further includes a spiral groove formed on the outer circumference of the transmission rod, the outer wall of the movable block is provided with a protrusion that slides and engages with the spiral groove, the transmission rod has an axially sliding movable sleeve that is fixedly connected to the protrusion, and the movable sleeve is fixedly connected to the movable crushing blade.

[0026] A control system for a customizable shearing, grinding, and blending soy milk maker includes the following steps:

[0027] Step 1: Add the required ingredients to the mixing bowl;

[0028] Step 2: Add water to the mixing tank. At the same time, the sensor body monitors the water temperature and raw material temperature in real time through the probe.

[0029] Step 3: The transmission rod rotates, which in turn drives the stirring blades and the fixed crushing blades to rotate. At the same time, the transmission rod also drives the movable crushing blades to rotate through the resistance adjustment mechanism.

[0030] Step 4: When the movable crusher blade encounters resistance, the resistance control mechanism adjusts the distance between the movable and fixed crusher blades to adjust the grinding intensity of the raw material.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] 1. This invention achieves the integrated automatic completion of sealing, locking and electrical connection during the sensor body assembly process through the cooperation of the positioning and pushing mechanism and the bidirectional sealing mechanism. When the sensor body is inserted into the sealing tube and rotated to the final position, the first spring drives the limiting plate to accurately embed into the arc-shaped groove. This action instantly and synchronously completes the rigid locking in the axial and circumferential directions, and ensures the reliable connection between the insertion contact head and the connecting contact head.

[0033] The final reset movement of the limiting plate pushes the sliding plate through its inner straight surface. The force is amplified and precisely transmitted through the linkage mechanism, forcibly pulling the movable sealing disc to move along the probe axial direction, so that it and the pre-positioned fixed sealing disc form a balanced clamping of the flexible sealing ring from both sides. Through bidirectional sealing, not only is the risk of sealing failure caused by improper torque in the traditional threaded fastening method completely eliminated, but also a redundant sealing barrier is constructed by the two parallel sealing surfaces working together to compress the sealing ring.

[0034] 2. By sensing the resistance through the resistance control mechanism, the distance between the movable and fixed crushing blades can be automatically adjusted, thereby adjusting the grinding intensity. When encountering large hard particles in the early stage of grinding, the resistance control mechanism controls the movable crushing blade to move towards the fixed crushing blade, reducing the gap between them. This transforms the hard-on-hard impact into a powerful capture and stable compression shearing of the material, significantly improving the initial crushing success rate of large particles, while greatly reducing the energy loss from material splashing and blade idling.

[0035] As the material is gradually crushed and the resistance decreases, the gap between the moving and stationary crushing blades increases again. The increased gap allows the fine particles that have been initially crushed to circulate and flow more fully, thereby avoiding excessive grinding and heat accumulation in local areas and promoting the uniform refinement of the slurry throughout the entire tank.

[0051] Please see Figure 1 Figure 6 shows an embodiment of the present invention, an assembled waterproof smart temperature sensor comprising:

[0052] Sealing tube 1, and flexible sealing ring 2 disposed at the end of sealing tube 1;

[0053] Also includes:

[0054] The sensor body 8 is inserted into the sealing tube 1. The sealing tube 1 is provided with a positioning and pushing mechanism connected to the sensor body 8. A limiting plate 5 is connected to the positioning and pushing mechanism, and the positioning and pushing mechanism can lock the position of the sensor body 8 through the limiting plate 5.

[0055] A bidirectional sealing mechanism is provided on the sensor body 8 and cooperates with the limiting plate 5. The bidirectional sealing mechanism can perform a bidirectional sealing action on the flexible sealing ring 2 when the limiting plate 5 moves.

[0056] Specifically, to ensure that the water temperature does not deviate from the actual temperature due to the temperature of the raw materials when grinding soybeans, the temperature needs to be measured in real time by a sensor. For this purpose, the sensor body 8 needs to be kept in a sealed state. When the sensor needs to be assembled, the sensor body 8 can be inserted into the sealing tube 1. As the sensor body 8 moves down, it is positioned by the positioning and pushing mechanism, and its position is locked by the limiting plate 5. At the same time, the limiting plate 5 will also drive the bidirectional sealing mechanism to move. Under the action of the bidirectional sealing mechanism, the flexible sealing ring 2 is bidirectionally sealed, thereby ensuring that the sealing tube 1 itself is in a sealed state after the sensor body 8 is fully inserted into the sealing tube 1, thus ensuring the safe use of the sensor body 8.

[0057] Please see Figures 1-4 , Figure 6 The positioning and pushing mechanism includes a buffer tube 3 disposed on the outer wall of the sealing tube 1, a movable rod 4 slidably installed inside the buffer tube 3, the movable rod 4 being fixedly connected to the limiting plate 5, a limiting ring 401 abutting against the sealing tube 1 on the movable rod 4, a first spring 6 sleeved on the movable rod 4, the two ends of the first spring 6 abutting against the buffer tube 3 and the limiting ring 401 respectively, the positioning and pushing mechanism also includes a guide groove formed on the inner wall of the sealing tube 1, a limiting block 10 slidably fitted into the guide groove on the outer wall of the sensor body 8, and an arc-shaped groove 801 formed on the top of the sensor body 8 abutting against the limiting plate 5.

[0058] In detail, the bottom of the sensor body 8 is provided with a plug contact 9, and the inner wall of the bottom of the sealing tube 1 is provided with a connecting contact 7 that mates with the plug contact 9. Three sides of the limiting plate 5 are inclined, and the side of the limiting plate 5 facing the bottom of the sealing tube 1 is horizontal. The internal cavity of the sealing tube 1 can be divided into two: the larger one on the upper side is the limiting cavity, and the smaller one on the lower side is the positioning cavity. The flexible sealing ring 2 is made of flexible material and can deform to a certain extent. The hole between the sensor body 8 and the flexible sealing ring 2 is larger than the middle hole of the flexible sealing ring 2.

[0059] The guide groove can be divided into three sections: arc groove 101, vertical groove 102, and annular groove 103. The arc groove 101 is symmetrically arranged and the two arc grooves 101 are connected to each other. The arc groove 101 is arranged in a concave arc shape, and the most concave position is connected to one end of the vertical groove 102. The other end of the vertical groove 102 is connected to one end of the annular groove 103.

[0060] In the initial state, the sensor body 8 has not yet been inserted into the sealing tube 1. At this time, the two limiting plates 5 are located at the end of their strokes on the side closest to each other. The limiting ring 401 abuts against the outer wall of the sealing tube 1, that is, the distance between the limiting ring 401 and the inner wall of the end of the buffer tube 3 is the largest. The elongation of the first spring 6 in its natural state is greater than the maximum distance between the limiting ring 401 and the inner wall of the end of the buffer tube 3. Therefore, the first spring 6 is in a pre-compressed state and always provides the limiting ring 401 with a thrust toward the side closer to the sealing tube 1.

[0061] When it is necessary to assemble the sensor body 8, the sensor body 8 can be inserted into the sealing tube 1 from one end of the flexible sealing ring 2. The flexible sealing ring 2 deforms and makes room, so that the sensor body 8 can smoothly enter the limiting chamber of the sealing tube 1. Its outer wall first contacts the inclined surface of the top of the two limiting plates 5. Under the axial thrust of the sensor body 8 being inserted continuously, the thrust is decomposed into a normal component force along the inclined surface of the limiting plate 5, which forces the two limiting plates 5 to move away from each other. Driven by this component force, the two limiting plates 5 begin to move outward synchronously. The translation of the limiting plate 5 drives the limiting ring 401 set on it to move in the buffer tube 3 through the movable rod 4. The movement of the limiting ring 401 continuously compresses the first spring 6 located between it and the end of the buffer tube 3.

[0062] As the sensor body 8 continues to move downward, its bottom end enters the positioning chamber below from the limiting chamber. At the same time, the limiting block 10 set on the outer wall of the sensor body 8 moves to the position aligned with the entrance of the arc groove 101 on the inner wall of the sealing tube 1. Guided by the arc trajectory of the arc groove 101, the limiting block 10 controls the sensor body 8 to rotate until the limiting block 10 moves to the position where the arc groove 101 and the vertical groove 102 are connected. In this state, the limiting plate 5 and the arc groove 801 are misaligned.

[0063] As the sensor body 8 continues to be pressed down, the limiting block 10 slides down along the vertical groove 102. When the limiting block 10 slides to the connection point between the vertical groove 102 and the annular groove 103, the pressing stops and the sensor body 8 is rotated slightly again. The limiting block 10 then slides from the vertical groove 102 into the annular groove 103 and is pushed to the end of the stroke of the annular groove 103 away from the vertical groove 102 as it rotates. At this time, the limiting plate 5 is in the position to cooperate with the arc-shaped groove 801. The first spring 6 is released elastically and pushes the movable rod 4 through the limiting ring 401, so that the two limiting plates 5 move toward each other. The inclined surfaces on both sides of the limiting plate 5 are tightly fitted with the side wall track of the arc-shaped groove 801.

[0064] In this state, the position of the sensor body 8 in the vertical direction is locked by the cooperation of the limiting block 10 and the annular groove 103. In the circumferential direction, the limiting plate 5 is constrained in the recessed position of the arc groove 801, and the first spring 6 always provides a pushing force to the limiting plate 5, thereby providing a locking torque to the sensor body 8 in the circumferential direction. At the same time, the insertion contact 9 at the bottom of the sensor body 8 and the connecting contact 7 at the bottom of the sealing tube 1 are in the connected state, thereby realizing the effect of integrated operation of positioning, locking and connection.

[0065] Please see Figures 1-3 , Figure 5 The bidirectional sealing mechanism includes a probe 11 disposed at the end of the sensor body 8, a fixed sealing disc 12 disposed on the probe 11, and a movable sealing disc 13 slidably disposed on the probe 11 axially. The fixed sealing disc 12 and the movable sealing disc 13 abut against the flexible sealing ring 2. It also includes a sliding component and an elastic component disposed on the sensor body 8. The sliding component includes a sliding sleeve 14 disposed on the movable sealing disc 13 and sleeved on the probe 11. The sensor body 8 has symmetrically arranged sliding grooves 802. A sliding plate 17 is slidably installed in the sliding grooves 802. A connecting rod 18 hinged to the sliding sleeve 14 is hinged to the sliding plate 17. The elastic component includes a guide post 15 disposed in the sliding grooves 802 and slidably connected to the sliding plate 17. A second spring 16 is sleeved on the guide post 15. The two ends of the second spring 16 abut against the inner wall of the sliding grooves 802 and the sliding plate 17, respectively.

[0066] Furthermore, the fixed sealing disc 12 and the movable sealing disc 13 are the same size. In the initial state, the sliding plate 17 is located at the end of the stroke of the slide groove 802 away from the probe rod 11, that is, the distance between the two sliding plates 17 is the largest. The extension of the second spring 16 in its natural state is greater than the length of the guide post 15. Therefore, the second spring 16 is in a pre-compressed state and always provides the sliding plate 17 with a thrust in the direction away from the probe rod 11. The sliding plate 17 will control the sliding sleeve 14 to be located at the end of the stroke of the side close to the sensor body 8 through the connecting rod 18, so that the distance between the movable sealing disc 13 and the fixed sealing disc 12 is the largest. When the sensor body 8 is assembled, the fixed sealing disc 12 is just in a tight fit with the flexible sealing ring 2.

[0067] When assembling the sensor body 8, the sensor body 8 can be inserted into the sealing tube 1. At the same time, the sensor body 8 will also drive the movable sealing disc 13 to move synchronously. When the movable sealing disc 13 comes into contact with the flexible sealing ring 2 and causes the flexible sealing ring 2 to deform and make way, the movable sealing disc 13 will also be completely inserted into the sealing tube 1.

[0068] When the sensor body 8 completes the final positioning and locking through the positioning and pushing mechanism, that is, when the limiting block 10 is pushed to the end of the stroke of the annular groove 103 away from the vertical groove 102, in this state, the fixed sealing plate 12 and the flexible sealing ring 2 are in a tight fit. The first spring 6 is then released elastically and pushes the two limiting plates 5 to reset inward. During this process, since the elastic potential energy of the first spring 6 is pre-compressed and stored is much greater than the pre-tightening force of the second spring 16, when the inner vertical surface of the limiting plate 5 that resets inward moves to contact the outer end of the sliding plate 17, its powerful thrust directly overcomes the resistance of the second spring 16, forcing the two sliding plates 17 to slide along the sliding groove 802 and move towards the direction close to the probe rod 11.

[0069] The sliding plate 17 will drive the sliding sleeve 14 to slide along the axial direction of the probe 11 via the connecting rod 18, and move away from the sensor body 8, so that the sliding sleeve 14 will drive the movable sealing disc 13 fixedly connected to it to slide towards the fixed sealing disc 12.

[0070] When the movable sealing disc 13 moves to fit tightly against the side of the flexible sealing ring 2 away from the fixed sealing disc 12, the limiting plate 5 moves to the end of its stroke. In this way, the flexible sealing ring 2 is firmly compressed between the two parallel end faces of the fixed sealing disc 12 and the movable sealing disc 13. Its material undergoes all-round elastic deformation under bidirectional pressure, which not only tightly fills all possible micro-assembly gaps between the probe 11 and the inner wall of the sealing tube 1, but also forms multiple reliable contact sealing bands between the sealing ring itself and the two sealing discs. This achieves bidirectional absolute isolation from water vapor environment corrosion factors, providing fundamental protection for the sensor body 8 to work stably for a long time under humid conditions.

[0071] Please see Figures 7-12 A customizable shearing, grinding, and blending soy milk maker, comprising:

[0072] Workbench 19, and mixing tank 20 disposed on workbench 19;

[0073] The transmission rod 22 is rotatably installed inside the mixing tank 20, and the transmission rod 22 is provided with a stirring blade 23 and a fixed crushing blade 24;

[0074] A resistance adjustment mechanism is provided on the transmission rod 22. A movable crushing blade 27 is connected to the resistance adjustment mechanism. The resistance adjustment mechanism can adjust the resistance between the movable crushing blade 27 and the fixed crushing blade 24 according to the resistance received by the movable crushing blade 27.

[0075] Specifically, a motor 21 is installed on the top of the mixing tank 20. The output shaft of the motor 21 is connected to the transmission rod 22. When grinding soybeans into soy milk, the grinding intensity needs to be adjusted according to the state of the soybeans. Therefore, when soybeans and water are added to the mixing tank 20, the motor 21 operates, driving the mixing blade 23 and the fixed crushing blade 24 to rotate via the transmission rod 22. The transmission rod 22 also drives the movable crushing blade 27 to move via a resistance adjustment mechanism. In the initial state, the soybeans are relatively hard and the degree of crushing is low, resulting in greater resistance to the movable crushing blade 27. Therefore, it is necessary to reduce the distance between the movable crushing blade 27 and the fixed crushing blade 24 to improve the grinding efficiency. The capture rate of materials and the success rate of one-time crushing are improved, and ineffective impacts and material splashing are reduced. To address this, under the action of resistance, the resistance control mechanism drives the movable crushing blade 27 to move towards the fixed crushing blade 24, thereby enhancing the grinding effect. As the degree of crushing of the beans increases, the resistance experienced by the movable crushing blade 27 decreases. The resistance control mechanism controls the movable crushing blade 27 to move away from the fixed crushing blade 24 to increase the gap between the two, allowing the material to circulate and flow more fully, achieving uniform and fine grinding, and avoiding local overheating or over-grinding. In this way, the beans can be fully processed and the efficiency of soy milk production can be improved.

[0076] Please see Figures 7-12 The resistance adjustment mechanism includes a movable block 25 slidably installed inside the transmission rod 22. A third spring 28 is provided inside the transmission rod 22 and abuts against the movable block 25. The resistance adjustment mechanism also includes a spiral groove 2201 formed on the outer circumference of the transmission rod 22. A protrusion 2501 is provided on the outer wall of the movable block 25 that slidably engages with the spiral groove 2201. A movable sleeve 26 is axially slidably connected to the protrusion 2501 and is fixedly connected to the movable crushing blade 27.

[0077] Please see Figure 11 Furthermore, the transmission rod 22 is partially hollow, and the third spring 28 abuts against the inner wall of the hollow bottom of the transmission rod 22. In the initial state, the movable block 25 is located at the end of its stroke away from the inner wall of the hollow bottom of the transmission rod 22, so that the protrusion 2501 is located at the end of its stroke on the side of the spiral groove 2201 closer to the motor 21. Under the action of the protrusion 2501, the movable crushing blade 27 is controlled by the movable sleeve 26 to be located at the end of its stroke away from the fixed crushing blade 24. The extension of the third spring 28 in its natural state is greater than the maximum distance between the movable block 25 and the inner wall of the hollow bottom of the transmission rod 22. Therefore, the third spring 28 is in a pre-compressed state and always provides the movable block 25 with a thrust toward the direction closer to the motor 21.

[0078] When it is necessary to grind the beans, the motor 21 starts and drives the transmission rod 22 to rotate at high speed. The rotation of the transmission rod 22 directly drives the stirring blade 23 and the fixed crushing blade 24 mounted on it to rotate synchronously, so as to form a basic stirring flow field and shearing action. At the same time, the rotation of the transmission rod 22 is forced to be transmitted to the movable sleeve 26 through the sliding engagement relationship between the spiral groove 2201 on its outer wall and the protrusion 2501 on the movable block 25. This causes the movable crushing blade 27, which is fixedly connected to the movable sleeve 26, to revolve with the transmission rod 22, forming a relative rotating shearing and grinding pair with the fixed crushing blade 24.

[0079] In the initial grinding stage, the beans are large, hard, and concentrated. When these hard materials enter the initial large gap between the movable crusher 27 and the fixed crusher 24, they will have a strong impact and resistance on the cutting edge of the high-speed rotating movable crusher 27, forming a huge reverse resistance torque. This resistance torque is transmitted to the movable block 25 through the movable sleeve 26 and the protrusion 2501, and is converted into a tangential force that attempts to prevent the movable block 25 from rotating synchronously with the transmission rod 22. Since the movable block 25 is restricted by the trajectory of the spiral groove 2201 through the protrusion 2501, the tangential force is decomposed into an axial component force that is inclined downward along the spiral groove 2201. This axial component force is sufficient to overcome the preload thrust of the third spring 28, forcing the movable block 25 together with the protrusion 2501 to slide along the trajectory of the spiral groove 2201 from the end near the motor 21 towards the hollow bottom of the transmission rod 22, thereby reducing the gap between the movable crusher 27 and the fixed crusher 24.

[0080] In this way, when encountering high-intensity resistance, the blades do not directly confront the material, causing it to splash or overload. Instead, they transform the impact collision into a gradual closing compression. The active narrowing of the gap between the movable crushing blade 27 and the fixed crushing blade 24 greatly enhances the mechanical capture and restraint of large particles entering the grinding zone, making it difficult for them to escape from the cutting edge. This makes each encounter of the cutting edges more likely to form effective shearing and crushing, thereby significantly improving the initial crushing success rate of hard materials, greatly reducing ineffective idle impacts and energy loss, and effectively suppressing splashing and noise caused by material bouncing.

[0081] As the grinding process progresses, the beans are gradually broken into smaller particles, and the overall hardness and size of the material decrease. The instantaneous impact resistance experienced by the movable crushing blade 27 is reduced accordingly, and the third spring 28 is released elastically, causing the movable block 25 to move toward its initial position. This increases the distance between the movable crushing blade 27 and the fixed crushing blade 24. With the increase in distance, the smaller particles that have been initially crushed are allowed to circulate and flow more smoothly in the increased gap, avoiding over-grinding or localized heat accumulation in a confined space. Instead, this promotes a more uniform distribution of the material throughout the mixing tank 20, allowing it to be further mixed by the stirring blade 23 and continuously finely sheared by the fixed crushing blade 24. Ultimately, this achieves adaptive processing throughout the entire process from coarse crushing to fine grinding.

[0082] A control system for a customizable shearing, grinding, and blending soy milk maker includes the following steps:

[0083] Step 1: Add the required ingredients to the mixing tank 20;

[0084] Step 2: Add water to the mixing tank 20. At the same time, the sensor body 8 monitors the water temperature and raw material temperature in real time through the probe 11.

[0085] Step 3: The transmission rod 22 rotates, which in turn drives the stirring blade 23 and the fixed crushing blade 24 to rotate. At the same time, the transmission rod 22 also drives the movable crushing blade 27 to rotate through the resistance adjustment mechanism.

[0086] Step 4: When the movable crusher 27 encounters resistance, the resistance control mechanism adjusts the distance between the movable crusher 27 and the fixed crusher 24 to adjust the grinding intensity of the raw material.

[0087] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
