Description

[0001] Priority application

[0002] This application claims priority to Chinese Invention Patent Application No. [2024111552292], filed on August 21, 2024, entitled "[An Intelligent Household Tofu Machine and Its Pressing Mechanism and Brine Coagulation Mechanism]", which is incorporated herein by reference in its entirety. Technical Field

[0003] This invention belongs to the field of food processing equipment technology, specifically relating to an integrated intelligent household tofu machine and its working method. Background Technology

[0004] There are currently three main methods for making tofu: large-scale assembly line production, commercial medium-sized equipment, and manual production using molds. Medium-to-large-scale equipment typically has separate, independent grinding, boiling, and pressing modules. The grinding module includes a grinding cup, the boiling module includes a boiling cup, and the pressing module includes a pressing box. The grinding cup grinds the material to produce a slurry, which is then discharged into the boiling cup for cooking. The cooked soy milk is then filtered and discharged into the pressing box for coagulation and pressing. However, the independent setup of each module makes the entire machine bulky, and the numerous cleaning components make it cumbersome to use. Manual production using molds is also overly complicated and requires a high level of experience.

[0005] As a result, various household tofu machines have appeared on the market. For example, Chinese invention patent application number 201110445428.3 discloses a household tofu machine, including a base, a soymilk maker, a tofu forming box, and a control circuit. Between the tofu forming box and the soymilk maker cup, there is a flow guiding and mixing device for mixing soymilk concentrate and coagulant. The outlet of the coagulant in the coagulant injection device is placed in the flow guiding and mixing device. It automatically completes the process steps of making tofu, including beating, filtering, coagulating, and tofu forming, on a single tofu machine. In the coagulating step, it fully improves the uniformity of mixing between soymilk concentrate and coagulant, resulting in better quality and taste of the formed tofu.

[0006] For example, Chinese invention patent application number 201410500532.1 discloses a household tofu machine, including a coagulation box, a boiling cup, and a pressing module. The pressing module includes a pressure plate and a driving mechanism for driving the pressure plate. The coagulation box is connected to the boiling cup, and the coagulating agent in the coagulation box is discharged into the boiling cup to achieve coagulation. The pressing module is located above the boiling cup. The pressure plate has a drainage groove / hole for filtering out yellow soy milk. The driving mechanism drives the pressure plate to move along the inner wall of the boiling cup and squeeze out the yellow soy milk through the drainage groove / hole to achieve tofu pressing. In this way, boiling, coagulation, and tofu pressing are all completed in the same cup.

[0007] However, the above solution has at least the following shortcomings:

[0008] 1. The filter screen is located inside the container, making it difficult to clean;

[0009] 2. The types of tofu produced are limited;

[0010] 3. The halogen agent is added by pressurizing with an air pump, which involves complex equipment, high cost, and difficulty in controlling the amount.

[0011] 4. Draining the water upwards will cause the tofu to soak in the yellow water for a long time, affecting the quality of the tofu. Summary of the Invention

[0012] The purpose of this invention is to provide a simple, integrated, fully automatic, intelligent household tofu machine and its working method, so as to partially alleviate or solve the above-mentioned shortcomings and meet the diverse tofu production needs of small household tofu machines.

[0013] To solve the aforementioned technical problems, the present invention specifically adopts the following technical solution:

[0014] An integrated intelligent household tofu machine includes a water storage module, a grinding module, a filtering module, a coagulation mechanism, and a pressing mechanism. The grinding module contains a heating element. The water storage module is connected to the grinding module via a pipeline. The outlet end of the grinding module corresponds to the inlet end of the filtering module. The filtering module and the coagulation mechanism are connected to the pressing mechanism via a Y-shaped connector. Specifically, the outlet end of the filtering module is connected to the first inlet of the Y-shaped connector, the powder outlet channel of the coagulation mechanism is connected to the second inlet of the Y-shaped connector, and the feed inlet of the pressing mechanism is connected to the discharge outlet of the Y-shaped connector. The powder outlet channel is divided into a vertical section and an inclined section from its first end to its second end. The vertical section is parallel to the height direction of the tofu machine, and the inclined section... The inclined section is coaxial with the pipe section where the second inlet is located; the halogenation mechanism includes a halogenation bottle, a docking seat, and a first driving device, as well as a push-type halogenation switch disposed on the halogenation bottle; the halogenation bottle is provided with a powder outlet that cooperates with the powder outlet channel; the docking seat has an opening at the top, and the docking seat forms a first groove, a second groove, and a third groove that are connected sequentially from the first end to the second end; the powder outlet channel is disposed at the bottom of the first groove; the halogenation bottle and the first driving device are respectively installed in the first groove and the third groove; the pressing part of the halogenation switch and the output end of the first driving device extend out of the first groove and the third groove respectively and are located in the second groove; the pressing part is provided with a slot, and the output end abuts in the slot.

[0015] As an improvement, the Y-shaped connector includes a first feeding section arranged along a first direction, a second feeding section arranged along a second direction, and a discharge section arranged along a third direction.

[0016] As an improvement, the inner diameter of the discharge section gradually decreases from the inlet end to the outlet end.

[0017] As an improvement, the diameter of the discharge section is smaller than the diameter of the first feed section.

[0018] As an improvement, the bottle mouth of the halogen dispensing bottle is provided with a bottle cap, and the bottle cap has a receiving cavity for installing the halogen dispensing switch. The bottle cap has an opening on one side. The halogen dispensing switch includes a reset member and a slider. One end of the reset member is fixed to the bottle cap, and the other end of the reset member is fixed to the slider. The second end of the slider extends out of the receiving cavity to form the pressing part. The powder outlet includes a first opening on the first side of the bottle cap and a second opening on the second side of the bottle cap corresponding to the powder outlet channel. The first opening and the second opening are offset. The slider has a powder-taking channel. When the halogen dispensing switch is not subjected to external force, the first opening corresponds to the powder-taking channel, and the halogen enters the powder-taking channel through the first opening. When the slider moves in a first direction, the powder-taking channel corresponds to the powder outlet channel, and the slider blocks the first opening, allowing the halogen in the powder-taking channel to enter the powder outlet channel.

[0019] As an improvement, the pressing mechanism includes a pressing chamber with a top opening, a pressing plate disposed above the pressing chamber, and a second driving device for driving the pressing plate into or away from the pressing chamber. A water filtering component is disposed inside the pressing chamber, and a lower chamber inner wall with a top opening is disposed below the water filtering component. A water-blocking component is installed at the top opening of the lower chamber inner wall. The water-blocking component and the lower chamber inner wall enclose a sealed space for installing a third driving device. A water storage space is formed between the lower chamber inner wall and the pressing chamber. The water-blocking component includes a first water-blocking plate that cooperates with the water filtering component. A second water-blocking plate extends from the periphery of the first water-blocking plate towards the bottom of the pressing chamber, and the height of the second water-blocking plate is greater than the distance between the water filtering component and the top of the lower chamber inner wall.

[0020] As an improvement, a sealing groove is provided on the upper surface of the first water baffle, and a sealing element is provided in the sealing groove.

[0021] As an improvement, the pressing mechanism includes a second driving device, a pressing plate, a pressing chamber, and a wastewater box arranged sequentially from top to bottom; the pressing chamber has an opening at the top, and a water filtering component and a water blocking component are arranged sequentially from top to bottom inside the pressing chamber. The water filtering component has multiple water filtering holes, and the second driving device is used to drive the pressing plate closer to or away from the water filtering component; the water blocking component includes a stop turntable, a turntable cover, and a third driving device for driving the stop turntable to rotate, arranged sequentially from top to bottom; the stop turntable includes a first region and a downward indentation along the edge of the first region. The second region is formed, and the second region is provided with a plurality of water-permeable holes that cooperate with the water-filtering through holes. The lower surface of the water-filtering component is provided with a first mounting groove that cooperates with the first region. The turntable cover is provided with a receiving cavity for installing the cut-off turntable. The edge of the receiving cavity is recessed downward to form a second mounting groove that cooperates with the second region. The second mounting groove is provided with a drainage channel corresponding to the water-filtering through holes. The drainage channel passes through the bottom of the pressing chamber and communicates with the wastewater box. The pressing chamber, the water-filtering component, and the turntable cover cooperate to form a sealed space for installing the third drive device.

[0022] This invention also provides a method for operating an integrated intelligent household tofu maker, which includes the following steps:

[0023] S201 The user adds clean water to the water storage module and soybeans to the grinding module, and starts the tofu machine;

[0024] S202 The water in the water storage module is quantitatively extracted into the grinding module, and the grinding module alternately grinds and heats the raw material to convert it into soy milk;

[0025] S203 adds a quantitative amount of halogenating agent through the halogenation mechanism;

[0026] S204 draws the soy milk into the filtration module for filtration, and then allows the filtered soy milk to enter the pressing mechanism;

[0027] After the S205 soy milk and the coagulant are mixed and cooled in the pressing mechanism to form tofu pudding, the pressing mechanism presses the tofu pudding to form tofu.

[0028] As an improvement, S205 further includes: simultaneously discharging the liquid generated during the pressing process while pressing the tofu pudding.

[0029] The principle and beneficial technical effects of this invention are as follows: Based on powdered coagulant, this application provides a fully automatic integrated tofu machine that does not require stirring and facilitates the production of different types of tofu.

[0030] On the one hand, the coagulation bottle in this application adopts a one-button press-type installation. Specifically, the coagulation bottle cooperates with the first driving device by setting a slot and is fixed in the first groove by snap-fit. When disassembling, by pressing the pressing part of the coagulation bottle, the output end of the first driving device is disengaged from the slot, and the coagulation bottle can be easily removed. This makes it convenient to replace the coagulation bottle containing different brine agents or different powder extraction amounts to meet the user's diverse needs for tofu.

[0031] On the other hand, by setting a Y-shaped connector to connect the pressing mechanism with the brine-adding mechanism and the filtering module respectively, the process of continuously pouring soy milk into the pressing mechanism after the brine-adding agent enters the pressing mechanism can fully stir the brine in the pressing mechanism and the brine remaining in the Y-shaped structure without the need to set up an additional stirring mechanism. In addition, the special design of the Y-shaped connector, such as the inner diameter of the discharge section decreasing from large to small, can increase the water pressure when the soy milk is poured into the pressing mechanism, resulting in better stirring effect. At the same time, the bending design of the discharge channel can effectively prevent soy milk (especially under increased water pressure) from flowing back into the bottle cap.

[0032] Furthermore, the two openings on the bottle cap are designed to be staggered. The powder dispensing channel on the slider cooperates with the two openings to dispensing and adding powder. Without external force, the powder dispensing channel always corresponds to the first opening. This not only provides a sealing effect, but also allows sufficient time for the halogen agent to enter the powder dispensing channel, resulting in a better quantitative dispensing effect.

[0060] Example 1

[0061] See Figure 1 This application provides a brine-dispensing mechanism for a household tofu machine, including: a brine-dispensing bottle 402, a docking seat 403, and a first driving device 401, as well as a push-type brine-dispensing switch disposed on the brine-dispensing bottle; wherein, the first driving device may be an electric push rod.

[0062] See Figure 2 and Figure 3 The halogen bottle is provided with a powder outlet, the top of the docking seat is open, and the docking seat forms a first groove, a second groove and a third groove that are connected in sequence from the first end to the second end. The bottom of the first groove is provided with a powder outlet channel 408. The halogen bottle and the first driving device 401 are respectively installed in the first groove and the third groove. The pressing part of the halogen switch and the output end of the first driving device extend out of the first groove and the third groove respectively and are located in the second groove. The pressing part is provided with a slot, and the output end abuts in the slot.

[0063] When the output end of the first driving device moves along the first direction, the first driving device drives the pressing part to move along the first direction to open the powder outlet, so that the halogen in the halogen bottle can enter the powder outlet channel through the powder outlet; when the first driving device moves along the second direction, the first driving device drives the pressing part to reset and block the powder outlet; wherein, the first direction is opposite to the second direction.

[0064] When the pressing part is manually pressed in the first direction, the output end disengages from the slot, allowing the halogen bottle and the halogen switch to be removed from the docking seat.

[0065] In some embodiments, the bottle mouth of the halogen dispensing bottle is provided with a bottle cap 405, and the bottle cap 405 is provided with a receiving cavity for installing the halogen dispensing switch. The bottle cap is open on one side. The push-type halogen dispensing switch includes a reset member 406 and a slider 407. One end of the reset member 406 is fixed to the bottle cap 405 (e.g., on the inner wall of the bottle cap), and the other end of the reset member 406 (preferably a spring) is fixed to the slider 407. The extension and retraction direction of the reset member 406 is parallel to the first direction and the second direction. The second end of the slider extends out of the receiving cavity to form the pressing part. Correspondingly, the powder outlet includes a first opening provided on the first side of the bottle cap and a second opening provided on the second side of the bottle cap and corresponding to the powder outlet channel. The first opening and the second opening are offset. The slider is provided with a powder picking channel 409. By changing the position of the slider 407, the position of the powder picking channel 409 is changed so as to correspond with the first opening and the second opening respectively to realize powder picking and feeding.

[0066] It should be noted that the 404 part of the body of the coagulation bottle can be made in different sizes. Similarly, the powder dispensing channel 409 of the slider can also be set in different sizes. According to the user's needs for the amount of tofu to be made, coagulation bottles and coagulation switches with different powder dispensing capacities can be replaced.

[0067] Specifically, when the halogen switch is not subjected to external force, the first opening corresponds to the powder-taking channel, and the halogen agent enters the powder-taking channel through the first opening to achieve quantitative powder taking; when the slider moves in the first direction under the action of external force, the powder-taking channel corresponds to the powder-discharging channel, and at the same time the slider blocks the first opening, and the halogen agent in the powder-taking channel enters the powder-discharging channel to achieve feeding; when the external force is removed, the reset member drives the slider to reset, and the powder-taking channel takes powder again to prepare for the next production.

[0068] When disassembling the halogen bottle, the operator presses the pressing part to separate it from the output end of the first driving device, and then lifts the halogen bottle upwards. Similarly, when installing the halogen bottle, the operator presses the pressing part, places the halogen bottle into the first groove, and then releases the hand. The pressing part is reset by the action of the reset member, so that the groove of the pressing part locks into the output end of the first driving device, thereby restricting the pressing part within the first groove.

[0069] In some embodiments, the powder outlet channel 408 is divided into a vertical section and an inclined section from its first end to its second end. The vertical section is parallel to the height direction of the tofu machine, and the inclined section is arranged along the second direction, so that a bending structure is formed at the connection between the vertical section and the inclined section. When feeding, the brine first falls quickly through the vertical section, and then enters the pressing mechanism through the inclined section. Its bending structure can effectively prevent the soy milk from flowing back into the bottle cap during the pouring process.

[0070] In some embodiments, the width of the second groove is smaller than the width of the first groove and the third groove, so as to confine the brine bottle and the first driving device within the first groove and the third groove, respectively.

[0071] In some embodiments, the width of the pressing part (slider) is close to the width of the second groove. For example, when the pressing part is installed in the second groove, both sides of the pressing part abut against the inner wall of the second groove to prevent the halogen bottle from shifting during the pressing process.

[0072] In some embodiments, the height of the pressing part is higher than the height of the second groove, thereby making it easier for the user to quickly find the point of force when pressing manually.

[0073] In some embodiments, the top of the pressing part is provided with scale lines to facilitate the user to control the pressing pressure according to the scale lines and prevent excessive pressing from causing mis-dispensing.

[0074] In other embodiments, the length of the pressing part is less than the minimum distance between the powder taking channel and the powder discharging channel. That is, when the end of the pressing part is flush with the brine bottle or the bottle cap during the pressing process, the user's finger is blocked and cannot continue to press inward. At this time, the powder taking channel is not yet aligned with the powder discharging channel. When feeding, the pressing part is driven to continue to move inward by the output end of the first driving device to realize feeding. This can avoid the user accidentally adding the brine during the process of changing the brine bottle.

[0075] In some specific embodiments, when the output end of the electric push rod moves to its maximum extent in the first direction, and / or when the reset member is compressed to its maximum extent, the powder outlet channel and the powder collection channel correspond.

[0076] In some embodiments, the brine-adding bottle is provided with a powder inlet for convenient feeding, so that the brine-adding bottle can be reused to reduce costs. In some specific embodiments, the powder inlet can be provided at the bottom of the brine-adding bottle, or the bottle cap is detachably connected to the brine-adding bottle, wherein the bottle cap is provided with an internal thread, and the bottle mouth of the brine-adding bottle is provided with an external thread that matches the internal thread, so that the user can remove the bottle cap and add the material through the bottle mouth.

[0077] In some embodiments, the inner diameter of the first groove gradually decreases from its top to its bottom, so that the opening end of the first groove forms an upward-facing mounting slope, thereby reducing the installation difficulty of the brine bottle.

[0078] Most existing technologies use liquid halogens, but liquid halogens are prone to sedimentation, requiring stirring before each use. Furthermore, liquid halogens are easily deteriorated, placing high demands on the sealing performance of the halogenation dispensing mechanism. Therefore, existing technologies typically aim to minimize disassembly, requiring only the cleaning of certain parts (such as the air inlet pipe). However, ensuring the quality of the halogen inside the dispensing container (e.g., the dispensing bottle) and effectively cleaning the container remains challenging. This application proposes a halogenation dispensing mechanism for powdered halogens. Firstly, the dispensing bottle in this solution uses a one-button press for dispensing, eliminating the need for additional pumps or other structures to stir the halogen. The structure is simple and convenient to use. Specifically, the dispensing bottle in this application... The bottle cap has through holes in different positions, which cooperate with the powder dispensing channel on the slider to achieve quantitative powder dispensing without manual intervention. Furthermore, for different tofu production volumes, the coagulation switch with different sized powder dispensing channels can be replaced, and users can make different types of tofu (such as silken tofu, gypsum tofu, brine tofu, etc.) by changing the coagulation bottle containing different brine agents. On the other hand, users can install and remove the coagulation bottle by pressing the push-button coagulation switch. That is to say, through the structural features of the coagulation switch and the first drive device itself, combined with the docking seat structure with multiple limit grooves, the coagulation mechanism can be quickly installed and removed without the need for additional fixing structures, making it convenient for users to pick up and put down the coagulation bottle for operations such as adding materials or cleaning.

[0079] Example 2

[0080] See Figures 4-8This embodiment provides a pressing mechanism for a household tofu machine. The tofu machine includes a pressing chamber with a top opening, a pressing plate 510 above the pressing chamber, and a second driving device 501 for driving the pressing plate 510 into or away from the pressing chamber. A water filtering component 512 is provided inside the pressing chamber, and a lower chamber inner wall 517 with a top opening is provided below the water filtering component 512. A water-blocking component 513 is installed at the top opening of the lower chamber inner wall 517. The water-blocking component 513 and the lower chamber inner wall 517 enclose a sealed space for installing a third driving device. A water storage space is formed between the lower chamber inner wall 517 and the pressing chamber.

[0081] The water-blocking component 513 includes a first water-blocking plate that cooperates with the water-filtering component 512. The periphery of the first water-blocking plate extends toward the bottom of the pressing chamber to form a second water-blocking plate. The height of the second water-blocking plate is greater than the distance between the water-filtering component 512 and the top of the inner wall 517 of the lower chamber.

[0082] In some embodiments, a sealing strip is provided between the second baffle and the inner wall 517 of the lower compartment.

[0083] When the third driving device drives the water-blocking component 513 to move closer to the water-filtering component 512, and the water-blocking component 513 abuts against the bottom of the water-filtering component 512, the water-filtering holes on the water-filtering component 512 are blocked; when the third driving device drives the water-blocking component 513 to move away from the water-filtering component 512, the water-filtering holes on the water-filtering component 512 open, and liquid can enter the water storage space along the water-blocking component 513.

[0084] In some embodiments, the water filter component 512 has multiple water filter holes, which are evenly distributed on the water filter component 512 and correspond to the water blocking component 513.

[0085] In some embodiments, the upper surface of the water-blocking component 513 (first water-blocking plate) is provided with a sealing groove, and a sealing element (preferably a plastic sealing strip) is provided in the sealing groove.

[0086] In some embodiments, the third driving device includes a first lifting device 516 for driving the water-blocking component 513 closer to or away from the water-filtering component 512, and a first guide post 514 for limiting the movement direction of the water-blocking component 513; the second driving device 501 includes a second lifting device 506 for driving the pressing plate 510 closer to or away from the water-filtering component 512, and a second guide post 508 for limiting the movement direction of the pressing plate 510; in some specific embodiments, the first / second lifting device includes a motor and a lead screw, and the first / second guide post is an optical axis. The working principle of the specific driving device can be found in 202223364700.8.

[0087] In some embodiments, a pressure sensor 509 is provided between the pressing plate 510 and the output end of the second driving device 501. The pressure sensor 509 collects the pressing pressure in real time, so that the pressing process is carried out at a reasonable speed, thereby improving the texture of the tofu.

[0088] In some embodiments, the pressing chamber includes an upper pressing chamber 502 and a lower pressing chamber 503 arranged sequentially from top to bottom. The top and bottom of the upper pressing chamber 502 and the top of the lower pressing chamber 503 are provided with openings. The water filtering component 512 is disposed at the bottom of the upper pressing chamber 502. The inner wall 517 of the lower chamber and the water-blocking component 513 are both located inside the lower pressing chamber 503. The upper pressing chamber 502 and the lower pressing chamber 503 are tightly connected by a fastening member 515.

[0089] The upper pressing chamber 502 and the lower pressing chamber 503 are respectively provided with a first fastening member and a second fastening member. When the first fastening member and the second fastening member are fastened together, the upper pressing chamber 502 and the lower pressing chamber 503 are locked together to form the pressing chamber. When the first fastening member and the second fastening member are opened, the upper pressing chamber 502 can be detached from the lower pressing chamber 503. The upper pressing chamber 502 and the lower pressing chamber 503 adopt a split design. After pressing is completed, the upper pressing chamber 502 can be removed to facilitate the removal of tofu and the cleaning of the upper pressing chamber 502 and the water filtering component 512 disposed within the upper pressing chamber 502.

[0090] In some specific embodiments, the bottom of the pressing chamber 502 extends inward to form a mounting platform perpendicular to the side wall of the pressing chamber 502. The water filter component 512 is placed on the mounting platform, so that the water filter component 512 can be easily removed for cleaning. Moreover, the width of the mounting platform is much smaller than the width of the water filter component 512, thereby avoiding obstruction of the water filter holes on the water filter component 512.

[0091] In some embodiments, the tofu machine is provided with a sliding member 504, and the pressing chamber is slidably disposed on the tofu machine via the sliding member 504; specifically, a slide rail can be provided on the tofu machine, and a pulley can be provided at the bottom of the pressing chamber, that is, the pressing chamber adopts a "pull-out" design, which makes it convenient to take out the tofu.

[0092] In some embodiments, the pressing chamber is provided with a feed inlet, and a Y-shaped connector 505 is provided at the feed inlet. The first inlet and the second inlet of the Y-shaped connector 505 are respectively connected to the filter module and the brine-adding mechanism of the household tofu machine.

[0093] In some embodiments, a drain outlet 519 is provided at the bottom of the pressing chamber.

[0094] In practical use, the upper pressing chamber is installed on the lower pressing chamber and locked together by the first and second fastening parts. The third driving device blocks the water-blocking component from below the water-filtering component. Soy milk and brine are added to the upper pressing chamber. After the soy milk coagulates, the third driving device moves the water-blocking component away from the water-filtering component to expose the filter holes. The second driving device drives the pressing plate to press the tofu. Wastewater (yellow water) generated during the pressing process can flow through the filter holes on the water-filtering component to the upper surface of the water-blocking component (i.e., the upper surface of the first water-blocking plate). It then flows along the first water-blocking plate to the second water-blocking plate arranged around the first water-blocking plate for diversion. The diverted wastewater flows along the second water-blocking plate into the water storage space for temporary storage. After pressing, the wastewater in the water storage space is discharged through the drain. Finally, the pressing chamber is pulled off the tofu machine, the fastening parts are opened, and the upper pressing chamber is removed to facilitate the removal of the tofu.

[0095] In the prior art (201110353816.9), the drive mechanism controlling the lifting and lowering of the sealing plate is located outside the slurry container. It is connected to the drive mechanism through the slurry container via a transmission component (switch plate). On the one hand, the external drive device requires more space and is not suitable for small household tofu machines, and its appearance is also not aesthetically pleasing. On the other hand, this installation method requires an opening in the container, making it difficult to guarantee its airtightness. In contrast, the drive device in this application adopts an internal design. Specifically, on the one hand, a sealed space for installing the third drive device is formed between the inner wall of the lower compartment and the water-blocking component, effectively ensuring the waterproof performance of the third drive device. Moreover, the internal design can greatly reduce the noise of the household tofu machine during operation. On the other hand, the lower compartment and the inner wall of the lower compartment enclose a water storage space, eliminating the need for an additional separate water storage mechanism (such as a wastewater box). Furthermore, the water-blocking component can effectively divert wastewater, thus meeting the rapid drainage needs of small-volume household tofu machines.

[0096] In summary, this application provides a pressing mechanism based on a built-in drive device and capable of rapid drainage in all directions, which can ensure the airtightness of the tofu machine while draining water quickly, thus meeting the needs of small household tofu machines.

[0097] Example 3

[0098] See Figures 9-18 This embodiment provides another pressing mechanism for a household tofu machine, including a second driving device 501, a pressing plate 510, a pressing chamber, and a wastewater box 6 arranged sequentially from top to bottom; the pressing chamber has openings at the top and bottom, and a water filtering component and a water blocking component are arranged sequentially from top to bottom inside the pressing chamber. The water filtering component has multiple water filtering holes, and the second driving device 501 is used to drive the pressing plate 510 to move closer to or away from the water filtering component;

[0099] In some embodiments, the second driving device 501 includes a second lifting device for driving the pressing plate 510 closer to or away from the water filtration component, and a second guide post for limiting the movement direction of the pressing plate 510. In some specific embodiments, the two lifting devices include a motor and a lead screw, and the two guide posts are optical axes. The working principle of the specific driving device can be found in 202223364700.8. The driving device with the above structure, under the action of the second guide member, can prevent the pressing plate 510 from rotating during the pressing process, thereby ensuring the pressing effect.

[0100] The water-blocking component includes a stop turntable 522, a turntable cover 523, a third drive device 526, and a bottom cover 524 arranged sequentially from top to bottom. The bottom cover 524 is installed at the bottom of the pressing chamber. The stop turntable 522 is provided with a plurality of water-permeable holes 5224 that cooperate with the water-filtering through holes. The turntable cover 523 and the bottom cover 524 are respectively provided with a drainage channel 5231 and a perforation corresponding to the water-filtering through holes. The top of the wastewater box 6 is provided with an opening that cooperates with the drainage channel 5231. The pressing chamber, the water-filtering component, the turntable cover 523, and the bottom cover 524 cooperate to form a sealed space for installing the third drive device 526.

[0101] In some embodiments, the bottom of the turntable cover 523 is provided with a mounting hole 5232 for mounting the third drive device 526. When the third drive device 526 is mounted in the mounting hole 5232, the bottom of the third drive device 526 is suspended, which further improves the waterproofness of the drive device.

[0102] In some embodiments, the pressing chamber includes an upper pressing chamber and a lower pressing chamber, the filter component is disposed at the bottom of the upper pressing chamber to separate the upper pressing chamber and the lower pressing chamber, and the water-blocking component is disposed in the lower pressing chamber.

[0103] When the third driving device 526 drives the shut-off turntable 522 to rotate, so that the water permeable hole 5224 and the water filter through hole correspond, the liquid in the pressing chamber can enter the wastewater box 6 in sequence through the water filter through hole, the water permeable hole 5224 and the drainage channel 5231; when the third driving device 526 drives the shut-off turntable 522 to rotate, so that the water permeable hole 5224 and the water filter through hole are misaligned, the shut-off turntable 522 blocks the water filter through hole.

[0104] In some embodiments, the bottom cover 524 is installed on the bottom of the pressing chamber in a detachable manner, thereby facilitating the inspection and replacement of components installed in the pressing chamber.

[0105] In some embodiments, the rotating cover 523 mounting plate is provided with a receiving groove, and the rotating cover 523 cutoff disc 522 is installed in the receiving groove, such that the mounting plate of the cutoff disc 522 and the upper surface of the rotating cover 523 are located on the same horizontal plane. This ensures that the upper surfaces of the cutoff disc 522 and the mounting plate are always in contact with the lower surface of the water filter component.

[0106] In some embodiments, the receiving groove is provided with an anti-slip element 5234, such as a sealing ring.

[0107] In some specific embodiments, the cutoff turntable 522 includes a first region 5221 and a second region 5222 formed by a downward indentation along the edge of the first region 5221. The lower surface of the first region 5221 is provided with a docking post 5223 for cooperating with the output shaft of the third drive device 526. The first region 5221, the second region 5222 and the docking post 5223 are coaxially arranged. The plurality of filter holes are evenly distributed in the second region 5222. Correspondingly, the lower surface of the filter component is provided with a first mounting groove for accommodating the first region 5221. The edge of the accommodating groove is recessed downward to form a second mounting groove 5233 that mates with the second region 5222. The drainage channel 5231 is provided on the second mounting groove 5233. The center of the turntable cover 523 is provided with a docking hole 5235 through which the docking post 5223 can pass. By setting the shut-off turntable 522 into a first region 5221 and a second region 5222 with different heights, even if a small amount of leakage occurs accidentally during the process of wastewater entering the drainage channel 5231 through the permeable hole 5224, its "stepped" design can confine the leaked wastewater within the second mounting groove 5233 and gradually enter the drainage channel 5231 for discharge. In addition, when the shut-off turntable 522 rotates, the second region 5222 of the shut-off turntable 522 can scrape the wastewater away to a certain extent within the second mounting groove 5233.

[0108] The bottom of the docking post 5223 is provided with a docking hole 5235, and the output shaft of the third driving device 526 can be inserted into the docking hole 5235 to drive the stop turntable 522 to rotate.

[0109] In some embodiments, the pressing chamber is provided with a feed inlet 525, and a Y-shaped connector is provided at the feed inlet 525. The first inlet and the second inlet of the Y-shaped connector are respectively connected to the filter module and the brine-adding mechanism of the household tofu machine.

[0110] In some embodiments, the pressing mechanism includes a mounting housing with an opening in one side wall. At least two slide rails of different heights are respectively provided inside the mounting housing along the direction from the opening to the opposite side. The wastewater box 6 and the pressing box are slidably disposed on the slide rails. The pressing chamber and the wastewater box 6 are respectively provided with handles 521. By pulling the handles 521, the pressing box and the wastewater box 6 can slide on the slide rails, making it convenient to remove the tofu from the pressing mechanism after pressing.

[0111] In some embodiments, a pressure sensor is provided between the pressing plate 510 and the output end of the second driving device 501. The pressing pressure is collected in real time by the pressure sensor, so that the pressing process is carried out at a reasonable speed, thereby improving the texture of the tofu.

[0112] In practical use, first, the water filtration holes of the filter component are blocked. Soy milk and brine are added to the pressing chamber. After the soy milk solidifies, the third driving device is used to offset the water permeable holes on the stop turntable from the water filtration holes on the filter component. The second driving device drives the pressing plate to press the tofu. During the pressing process, the wastewater (yellow water) generated can pass through the water filtration holes, the drainage channel and the perforation into the wastewater box. After pressing, the pressing chamber can be pulled out and the tofu can be taken out.

[0113] In summary, this application provides a drawer-type pressing mechanism based on a built-in drive device for miniaturized household tofu machines.

[0114] Specifically, the pressing chamber, the water filtering component, the turntable cover, and the bottom cover cooperate to form a sealed space for installing the third drive device. The built-in design can greatly reduce the noise of the household tofu machine during operation, and the third drive device adopts a suspended design, which can fully ensure the waterproofness of the equipment. On the other hand, the third drive device and the pressing chamber adopt an integrated design. After pressing is completed, the pressing chamber can be pulled out to remove the tofu. During this process, the third drive mechanism is always stably installed inside the pressing chamber, without the need for disassembly or assembly, and there is no need to worry about adverse effects on it during the process of removing and placing the pressing chamber.

[0115] Furthermore, the concave-convex structure design of the water-blocking component forms a stepped waterproof structure, and together with sealing components such as sealing strips, the water release performance between the water-blocking component and the filter component can be effectively guaranteed.

[0116] Example 4

[0117] See Figures 19-21 This application also provides an integrated intelligent household tofu machine, including a water storage module 1, a grinding module 2, a filtering module 3, a brine-adding mechanism 4, and a pressing mechanism 5; the grinding module 2 is equipped with a heating component 8, the water storage module 1 is connected to the grinding module 2 through a pipeline, the outlet end of the grinding module 2 corresponds to the inlet end of the filtering module 3, the filtering module 3 and the brine-adding mechanism 4 are connected to the pressing mechanism 5 through a Y-shaped connector, wherein the outlet end of the filtering module 3 is connected to the first inlet of the Y-shaped connector, the powder outlet channel of the brine-adding mechanism 4 is connected to the second inlet of the Y-shaped connector, and the feed inlet of the pressing mechanism 5 is connected to the discharge outlet of the Y-shaped connector.

[0118] Specifically, the Y-shaped connector includes a first feeding section arranged along a first angle, a second feeding section arranged along a second angle, and a discharge section arranged along a third angle, with the first inlet, the second inlet, and the discharge outlet respectively located at the ends of the first feeding section, the second feeding section, and the discharge section.

[0119] In some embodiments, the inner diameter of the discharge section gradually decreases from the inlet end to the outlet end, and / or the inner diameter of the first inlet section is larger than the inner diameter of the discharge section, so that the water pressure gradually increases when the soy milk enters the pressing chamber, thereby fully stirring the soy milk and brine in the pressing chamber.

[0120] In some embodiments, the powder outlet channel is divided into a vertical section and an inclined section from its first end to its second end. The vertical section is parallel to the height direction of the tofu machine, and the inclined section is coaxial with the pipe section where the second inlet is located. When feeding, the brine first falls quickly through the vertical section and then enters the pressing mechanism 5 through the inclined section. Its bending structure can effectively prevent the soy milk from flowing back into the bottle cap during the pouring process.

[0121] In other embodiments, the powder outlet channel is arranged vertically; correspondingly, the second feed section is arranged in the extension direction of the powder outlet channel, that is, the powder outlet channel, the second feed section and the discharge section are connected to form a straight pipe, so that the halogen can fall vertically from the feed channel into the pressing chamber, preventing the halogen from accumulating in the pipe.

[0122] In some embodiments, referring to Embodiment 1, the halogenation mechanism 4 includes a halogenation bottle 402, a docking seat, and a first driving device 401, as well as a push-type halogenation switch disposed on the halogenation bottle 402; the halogenation bottle 402 is provided with a powder outlet, the top of the docking seat is open, and the docking seat forms a first groove, a second groove, and a third groove that are connected sequentially from a first end to a second end, respectively; the powder outlet channel is disposed at the bottom of the first groove; the halogenation bottle 402 and the first driving device 401 are respectively installed in the first groove and the third groove, and the pressing part of the halogenation switch and the output end of the first driving device 401 extend out of the first groove and the third groove respectively and are located in the second groove; the pressing part is provided with a slot, and the output end abuts in the slot.

[0123] In some embodiments, the structure of the pressing mechanism 5 can be the same as that of the pressing mechanism 5 in Embodiment 2; in other embodiments, the pressing mechanism 5 can also adopt the structure of Embodiment 3.

[0124] In some embodiments, the water storage module 1 is a clean water tank for storing clean water, the grinding module 2 can adopt the grinding part structure in the prior art (e.g., a wall-breaking machine), the filtration part can be a filter cup with filter holes at the bottom, and of course, the tofu machine also includes an electrical compartment 7, which specifically includes a main control board, a drive device and a power supply; water pumps are provided on the pipeline between the water storage module 1 and the grinding module 2, and between the grinding module 2 and the filtration module 3.

[0125] For example, when the tofu machine is in use, after the machine is started, the water pump between the water tank and the grinding water path will add water from the water tank to the grinding part in a metered manner. First, the soybeans are cooked by the heating element, and then the soybeans are converted into soy milk by intermittent heating and grinding. Then, the coagulation mechanism will determine the amount of coagulation agent to be added according to the set data such as tofu type and tofu quality, and use the first driving device (such as an electric push rod) to add the coagulation agent in a metered manner to the pressing part. After the soy milk is made, the soy milk passes through the filtration device while it is hot to remove the soy residue, and then enters the pressing part. The coagulant is dissolved by the impact of soy milk, thus completing the coagulation process. The process of pouring soy milk in is similar to stirring, which allows the coagulant to dissolve fully. Specifically, the powdered coagulant falls into the water pipes, the soy milk flows through it, and then into the pressing container. This process takes about 40 seconds, which is enough to fully dissolve the coagulant. The tofu will gradually cool and solidify into tofu curd in the pressing mechanism. After it has solidified sufficiently, the screw motor will drive the pressing plate and other mechanisms to press the tofu into shape and remove the waste liquid such as yellow water generated.

[0126] After the tofu is removed, the remaining water in the clean water tank enters the grinding section for heating, and then enters each module in sequence to achieve self-cleaning.

[0127] In some embodiments, a water pump is provided in the wastewater box or the water storage space. The negative pressure of the water pump can effectively extract the wastewater from the upper pressing chamber to prevent water accumulation in the upper pressing chamber.

[0128] Compared to traditional tofu production machines, the intelligent home tofu machine in this embodiment adopts an integrated structure for the tofu coagulation container and pressing mechanism, combining the coagulation container and the tofu pressing and forming container into one unit, greatly reducing the machine's size. This invention simultaneously performs the grinding and boiling steps in tofu making, reducing production time. The use of dry soybean grinding technology eliminates the need for soaking soybeans. Compared to the 3-hour production time required by traditional commercial tofu machines, the tofu production time is reduced to approximately 50 minutes. Furthermore, traditional tofu machines require the coagulation agent to be dissolved before addition, which is inconvenient for storage. This invention can use powdered coagulation agent for tofu production, and by changing the coagulation agent, different types of tofu (gypsum tofu, brine tofu, glucono-delta-lactone tofu, etc.) can be produced.

[0129] Example 5
