Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and more particularly to a dual-drive forward and reverse drive structure and a seasoning box drive switching device thereof. Background Art

[0002] In the modern catering industry and home kitchens, the use of seasonings is an indispensable part of the cooking process. In the traditional cooking process, there are many types of seasonings, which are easy to spill when seasoning, and various liquid seasonings take up a lot of space and are not easy to store. The traditional seasoning method relies on manual operation, and the addition of seasonings often depends on the experience and feeling of the chef. It is not only inefficient and time-consuming, but also prone to inaccurate measurement and difficult to ensure sanitary conditions. Especially for people who are busy in the kitchen, finding a seasoning method that is simple and easy to use and can ensure a consistent taste of the dishes has become an urgent need. In order to meet the growing demand for efficient, healthy and convenient cooking, there is an urgent need for a fully automatic intelligent seasoning machine that can achieve high-precision quantification, simple operation and easy maintenance.

[0003] With the development of intelligent technology, sensor technology, automatic control systems and artificial intelligence algorithms are constantly improving, making it possible to achieve accurate quantification and precise control of seasonings, thereby ensuring the consistency of food taste and quality. Intelligent seasoning machines can also interact with users through interactive interfaces, and can provide personalized seasoning selection and matching suggestions according to different dish requirements and personal tastes. At the same time, they also have data recording and analysis functions, which can record the amount of seasoning and recipes used each time, provide users with subsequent references and adjustment suggestions, and bring users a more convenient and fast intelligent cooking experience. This intelligent seasoning management method can not only improve kitchen production efficiency and reduce food waste, but also meet the needs of different user groups for healthy diets and personalized tastes, greatly simplify the cooking process, improve the efficiency and convenience of kitchen work, and meet the pursuit of modern people for food quality and quality of life. It has broad application prospects.

[0004] In the automated seasoning box structure, the power structure for discharging is a very important part. Due to the variety of seasonings, a large number of unit boxes need to be set up. If each unit box is equipped with a power mechanism, the overall structure will be more complicated, and the volume of the entire seasoning box will also increase. Therefore, how to reduce the space occupied by the drive structure is particularly important for the small size and lightweight of the seasoning box. For the existing research direction, it tends to be more cylindrical. The cylindrical structural design allows each unit box containing seasoning to be designed around the axis to improve space utilization, but the discharging power at the bottom is not easy to match. Moreover, each unit box also needs to be fed regularly, which requires that multiple unit boxes should preferably be able to rotate to adapt to the window that pops up from the unit box. Therefore, this functionality is not easy to meet and is highly complex, which poses a problem for existing technicians.

[0005] Therefore, how to provide a structure and device that can be adapted to the use of cylindrical seasoning boxes and is conducive to reducing the space occupied by the drive structure is a problem that those skilled in the art urgently need to solve. Summary of the invention

[0006] In view of this, the present invention provides a dual-drive forward and reverse drive structure and a seasoning box drive switching device thereof, aiming to solve the above technical problems.

[0007] In order to achieve the above object, the present invention adopts the following technical solution:

[0008] A dual-drive forward and reverse drive structure, comprising: an outer shell, and also comprising: an upper drive disk and a lower drive disk rotatably connected to the inner side of the outer shell, wherein the upper drive disk and the lower drive disk are arranged in parallel and have a gap, and a bidirectional drive mechanism is arranged in the gap;

[0009] The bottom surface of the upper driving disk is embedded with an upper annular gear disk rotatably connected thereto, and the top surface of the lower driving disk is embedded with a lower annular gear disk rotatably connected thereto, and the upper annular gear disk and the lower annular gear disk are coaxially arranged; the bottom surface edge of the upper annular gear disk has an upper tooth pattern, and the top surface edge of the lower annular gear disk has a lower tooth pattern corresponding to the upper tooth pattern; elastic wedge-shaped portions are provided between the upper annular gear disk and the rotating circumferential surface of the upper driving disk, and between the lower annular gear disk and the rotating circumferential surface of the lower driving disk;

[0010] The bidirectional driving mechanism is connected to the inner wall of the outer shell and has a driving gear respectively meshed with the upper tooth pattern and the lower tooth pattern. When the driving gear rotates, the upper annular toothed disc and the lower annular toothed disc rotate in different directions. Under the action of the elastic wedge-shaped portion, the upper driving disc and the lower driving disc can only be driven to rotate in one rotation direction by the corresponding upper annular toothed disc and the lower annular toothed disc, and the directions in which the upper driving disc and the lower driving disc can be driven to rotate are opposite.

[0011] Through the above technical scheme, the present invention provides a structure that can drive two turntables to rotate in different directions by one power, and when one turntable rotates, the other turntable does not move. When the driving gear rotates, it can drive the upper and lower annular toothed discs to rotate in opposite directions. Due to the structural design of the elastic wedge-shaped part, when any annular toothed disc rotates, it can only drive the corresponding driving disc to rotate when it rotates in one direction, but cannot drive the corresponding driving disc to rotate when it rotates in the other direction. Under the design of this structure, the design of the power structure is reduced, space is saved, and the possibility of miniaturized and lightweight structural design is provided.

[0012] Preferably, in the above-mentioned dual-drive forward and reverse driving structure, the elastic wedge-shaped portion includes a wedge block and a spring; a wedge-shaped portion slide groove is provided on the outer circumferential wall of the upper annular gear disk and the lower annular gear disk, and the wedge block is slidably connected in the wedge-shaped portion slide groove; the spring is provided in the wedge-shaped portion slide groove and is connected between the bottom surface of the wedge-shaped portion slide groove and the wedge block, and under the elastic action of the spring, the wedge head of the wedge block is exposed on the outer circumferential wall of the upper annular gear disk and the lower annular gear disk; the inner wall surfaces of the upper drive disk and the lower drive disk corresponding to the wedge head are both provided with matching wedge grooves. The structure composed of the wedge block and the spring can make the wedge block compress the spring back into the wedge-shaped portion slide groove when a force is applied on one side, and cannot act when a force is applied on the other side, so that the annular gear disk can drive the corresponding drive disk to rotate when it rotates in one direction, but cannot drive the corresponding drive disk to rotate when it rotates in the other direction.

[0013] Preferably, in the above dual-drive forward and reverse drive structure, the inclined surface of the wedge-shaped head is processed into an outwardly convex arc surface. Designing the inclined surface of the wedge-shaped head into an arc surface makes it easier to move when pressed.

[0014] Preferably, in the above-mentioned dual-drive forward and reverse drive structure, the outer circumferential wall surfaces of the upper drive disk and the lower drive disk are both provided with elastic marbles, and the inner wall of the outer shell is provided with limiting grooves corresponding to the elastic marbles. The elastic marbles are provided to balance the friction between the drive disk and the annular gear disk, and between the drive disk and the outer shell, to prevent the drive disk from being driven to rotate by the annular gear disk because the friction between the drive disk and the outer shell is insufficient to resist the friction generated by the action of the wedge block between the drive disk and the annular gear disk. After the elastic marbles are designed, the elastic marbles can limit the erroneous rotation.

[0015] Preferably, in the above-mentioned dual-drive forward and reverse drive structure, the bidirectional drive mechanism includes a bidirectional drive motor, the housing of the bidirectional drive motor is fixed on the inner wall of the outer shell, and the power output shaft of the bidirectional drive motor is fixed to the drive gear. The bidirectional drive motor is used to control the drive gear to rotate in different directions, which has a simple structure and convenient control.

[0016] The present invention also provides a seasoning box drive switching device, comprising the above-mentioned dual-drive forward and reverse drive structure;

[0017] The center of the lower driving disk has a through hole, and a plurality of partition baffles are fixed around the through hole on the bottom surface of the lower driving disk, and the adjacent partition baffles limit and form a fan-shaped storage space, and a fan-shaped seasoning unit box is arranged in the fan-shaped storage space, and a plurality of the fan-shaped seasoning unit boxes are rotatably connected to the inner side of the outer shell, and the top surface of the fan-shaped seasoning unit box has a feeding port, and the bottom surface of the fan-shaped seasoning unit box has a discharging port;

[0018] A central axis is fixed at the center of the bottom surface of the upper driving disk, and the central axis passes downward through the through hole. A driving part is installed at the bottom end of the central axis. When the multiple fan-shaped seasoning unit boxes rotate around the central axis, the discharge control part on any discharge port can be coupled with the driving part and control the discharge of the discharge port.

[0019] Through the above technical scheme, the seasoning box drive switching device provided by the present invention can utilize the forward and reverse control of the dual-drive forward and reverse drive structure to realize the rotation control of the central axis or multiple fan-shaped seasoning unit boxes. The rotation object can be selected according to needs, which can greatly save space and meet usage requirements.

[0020] Preferably, in the above-mentioned seasoning box drive switching device, the bottom of the outer shell has a material receiving cavity, and a material receiving box is arranged in the material receiving cavity, and the material receiving box is located below the material outlet of any of the fan-shaped seasoning unit boxes. The material receiving box is arranged below the material outlet of any of the fan-shaped seasoning unit boxes to reduce the volume of the material receiving box, and will not cause the area of ​​the material receiving box to be too large, which will affect the seasoning sticking to the material receiving box and affect the gram weight.

[0021] Preferably, in the above-mentioned seasoning box drive switching device, the lower inner wall of the outer shell has an annular seasoning box slide rail, and the seasoning box slide rail is slidably connected to the arc-shaped edges at the bottom of the plurality of fan-shaped seasoning unit boxes. The seasoning box slide rail can support and guide the fan-shaped seasoning unit box, and the fan-shaped storage space formed by the partition baffle can well ensure the operation stability of the fan-shaped seasoning unit box.

[0022] Preferably, in the above-mentioned seasoning box drive switching device, a fan-shaped seasoning unit box pop-up door is provided on the side wall of the outer shell, and the fan-shaped seasoning unit box pop-up door corresponds to any of the fan-shaped storage spaces. The fan-shaped seasoning unit box pop-up door can conveniently take out the fan-shaped seasoning unit box and replenish the seasoning in the box body.

[0023] Preferably, in the above-mentioned seasoning box drive switching device, the number of the fan-shaped seasoning unit boxes is the same as the number of the elastic wedge-shaped parts arranged on the upper drive disk and the lower drive disk, and the plurality of elastic wedge-shaped parts correspond to the plurality of fan-shaped seasoning unit boxes, respectively, so as to ensure that the position correspondence after the structure is rotated is accurate.

[0024] It can be seen from the above technical solutions that, compared with the prior art, the present invention discloses a dual-drive forward and reverse drive structure and a seasoning box drive switching device thereof, which has the following beneficial effects:

[0025] 1. The present invention provides a structure that can drive two turntables to rotate in different directions by one power, and when one turntable rotates, the other turntable does not move. When the driving gear rotates, it can drive the upper and lower annular toothed discs to rotate in opposite directions. Due to the structural design of the elastic wedge-shaped part, when any annular toothed disc rotates, it can only drive the corresponding driving disc to rotate when it rotates in one direction, but cannot drive the corresponding driving disc to rotate when it rotates in the other direction. Under the design of this structure, the design of the power structure is reduced, space is saved, and the possibility of miniaturization and lightweight structural design is provided.

[0026] 2. The dual-drive forward and reverse drive structure provided by the present invention utilizes a structure composed of a wedge block and a spring, which enables the wedge block to compress the spring back into the wedge-shaped portion slide groove when a force is applied to one side, but cannot move when a force is applied to the other side. Therefore, it can satisfy that the annular gear disk drives the corresponding drive disk to rotate when it rotates in one direction, but cannot drive the corresponding drive disk to rotate when it rotates in the other direction.

[0027] 3. The seasoning box drive switching device provided by the present invention can utilize the forward and reverse control of the dual-drive forward and reverse drive structure to realize the rotation control of the central axis or multiple fan-shaped seasoning unit boxes. The rotation object can be selected according to needs, which can greatly save space and meet usage needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0096] In this embodiment, the implementation principles of the material receiving box linear track ejection mechanism 141 and the seasoning box linear track ejection mechanism 133 are basically the same. Specifically:

[0097] The linear track pop-up mechanism 141 of the material receiving box includes a linear telescopic rod 1411 of the material receiving box, the fixed rod end of the linear telescopic rod 1411 of the material receiving box is fixedly connected to the bottom inner wall of the material receiving chamber 14, the telescopic end of the linear telescopic rod 1411 of the material receiving box is fixed to the bottom end of the material receiving box pop-up door 142, and the telescopic end is provided with a material receiving box pop-up block 1412, and the arc-shaped edge at the bottom of the material receiving box 5 is provided with a material receiving box pop-up slot 1413. In this embodiment, the material receiving box 5 is also a fan-shaped box body. When the material receiving box 5 is located inside the material receiving cavity 14, the material receiving box pop-up block 1412 is always coordinated with the material receiving box pop-up slot 1413. When the material receiving box 5 needs to be popped out for use, it is only necessary to control the linear telescopic rod 1411 of the material receiving box to extend, so that the material receiving box pop-up door 142 and the material receiving box 5 can be popped out at the same time, and then the material receiving box 5 can be taken out; after pouring out the seasoning, the material receiving box 5 is put back, and then the linear telescopic rod 1411 of the material receiving box is controlled to be retracted, which can drive the material receiving box pop-up door 142 and the material receiving box 5 to be retracted at the same time.

[0098] In the drawings of this embodiment, a bottom cover is not shown at the bottom of the receiving chamber 14, but a bottom cover can be installed accordingly.

[0100] In this embodiment, a total of five groups of fan-shaped seasoning unit boxes 3 are provided, so the angle corresponding to each group of fan-shaped seasoning unit boxes 3 is 360° / 5=72°, so when the position of the previous group of fan-shaped seasoning unit boxes 3 is accurate, each rotation of 72° will cause the next group of fan-shaped seasoning unit boxes 3 to rotate to the correct position for subsequent discharging operations. Among them, the blade-type rotating discharging mechanism 6 and the negative pressure suction pump 7 are set to maintain an angle of 36°, that is, the angle between the bisectors of the two sub-fan-shaped unit boxes 33 is 36°.

[0101] The top of the fan-shaped seasoning unit box 3 is provided with a seasoning box cover 35 , and the seasoning box cover 35 has a corresponding seal and is buckled on the top opening of the fan-shaped seasoning unit box 3 .

[0102] See attached Fig.26 To Attachment Fig.33 The specific structure of the blade type rotating discharging mechanism 6 provided in this embodiment includes:

[0103] The rotation limiting shell 61 is a cylindrical shell with a horizontal axis, and the upper and lower opposite side walls of the rotation limiting shell 61 are respectively provided with an upper opening 611 and a lower opening 612, and closing plates 613 are fixed at both ends of the cylindrical shell, and the upper edge of the closing plate 613 is flush with the edge of the upper opening 611;

[0104] The quantitative blade part 62 includes a positioning block 621 and a plurality of blades 622 annularly fixed on the outer side of the positioning block 621. The positioning block 621 is coaxially arranged with the cylindrical shell, and the middle part of the positioning block 621 is rotatably connected with a closing plate 613. The plurality of blades 622 are fixed to the part of the positioning block 621 located inside the cylindrical shell, and a rotation hole 6211 is opened at the axis of the positioning block 621.

[0105] A lead screw 63, one end of which is rotatably connected in the rotating hole 6211, and the other end of which extends toward the central empty space of the plurality of blades 622. An adjusting nut 65 is threadedly connected to the rod body of the lead screw 63, and a first telescopic sleeve 66 is connected between the adjusting nut 65 and the positioning block 621, and the first telescopic sleeve 66 closes the opening of the lead screw 63 corresponding to the adjacent blade 622;

[0106] The blocking piece 64 is sleeved on the outer sides of the plurality of blades 622 and is provided with a sliding slot 641 for avoiding the blades 622 . The sliding slot 641 is slidably connected to the plurality of blades 622 . The middle part of the blocking piece 64 is fixed to the adjusting nut 65 .

[0107] In this embodiment, the discharge port 32 at the bottom of the sub-fan-shaped unit box 33 for containing solid seasoning is a square port, and the edge of the upper opening 611 of the rotation limiting shell 61 is fixedly connected to the square port.

[0108] In order to further optimize the above technical solution, it also includes a second telescopic sleeve 67, which is sleeved on the outside of the multiple blades 622, and the two end edges of the second telescopic sleeve 67 are respectively fixedly connected to the baffle 64 and the ends of the multiple blades 622 away from the positioning block 621.

[0109] In this embodiment, the first telescopic sleeve 66 and the second telescopic sleeve 67 may adopt a bellows structure or a multi-stage telescopic sleeve structure.

[0110] In order to further optimize the above technical solution, a horizontal blade rotation I-shaped slot 6212 is provided at the part of the positioning block 621 located outside the cylindrical shell, and a screw rotation I-shaped slot 631 is provided at the end of the screw 63 located in the rotating hole 6211, and an avoidance distance is provided between the end face of the screw rotation I-shaped slot 631 and the end face of the blade rotation I-shaped slot 6212.

[0111] In order to further optimize the above technical solution, an annular limiting groove 6213 is provided in the rotating hole 6211 , and an annular limiting protrusion 632 embedded in the annular limiting groove 6213 is provided on the outer wall of the lead screw 63 .

[0112] In order to further optimize the above technical solution, one side edge of the upper opening 611 of the rotation limiting shell 61 has an auxiliary arc top 614 extending upward along the curvature of the rotation limiting shell 61, and the auxiliary arc top 614 is set at the edge of the upper opening 611 on the rear side of the rotation direction of the blade 622.

[0113] In order to further optimize the above technical solution, fan-shaped quantitative cavities 623 are formed between adjacent blades 622 . In a stationary state, the upper fan-shaped quantitative cavity 623 corresponds to the upper opening 611 , and the lower fan-shaped quantitative cavity 623 corresponds to the lower opening 612 .

[0114] When quantitative adjustment is required, the lead screw 63 is turned to rotate. At this time, the positioning block 621 outside the lead screw 63 will not rotate. In order to meet this condition, the rotational friction between the positioning block 621 and the closing plate 613 can be increased, that is, a slight interference fit structure is set. When the lead screw 63 rotates, due to the restriction between the baffle 64 and the blade 622, the baffle 64 cannot rotate. Therefore, the adjustment nut 65 will move along the length direction of the lead screw 63, thereby adjusting the capacity of the fan-shaped quantitative cavity 623. When discharging is required, the positioning block 621 is turned to rotate, and the blade 622 rotates to discharge the material from the lower opening 612.

[0115] In this embodiment, if the second telescopic sleeve 67 is configured as a three-stage cylindrical telescopic sleeve structure: each layer of the cylinder corresponds to 0.5 g / cm 3 The volume of the material is 3 layers in total, two of which can be convex, and one layer can be compressed by 0.5g / cm 3 If there are two layers, the maximum volume can be increased from 1.5g / cm 3 , compression 1g / cm 3 volume, compressed to the smallest volume 0.5g / cm 3 Of course, the precision of the thread of the screw 63 and the number of turns of the adjusting nut 65 can achieve a value between 1.5 g / cm 3 With 0.5g / cm 3Adjustment of any volume. In addition, due to the friction in reality, the situation where the three layers come out in sequence is the ideal situation. Take the above content as a reference for capacity adjustment. If the three layers act at the same time, it will not affect the quantitative adjustment, and the volume is fixed.

[0116] It can be seen that in this embodiment, three powers are required for driving, namely, a discharging power source 41 and an adjusting power source 42; the discharging power source 41 includes a solid discharging power 411 and a liquid discharging power 412, the solid discharging power 411 is used to turn the positioning block 621, and the liquid discharging power 412 is used to drive the negative pressure suction pump 7; the adjusting power source 42 is used to turn the screw 63.

[0117] Furthermore, the solid discharging power 411 and the liquid discharging power 412 can be coupled to any group of positioning blocks 621 and the action end of the negative pressure suction pump 7 at the same time, and the regulating power source 42 is coupled to the screw 63 by switching the position with the solid discharging power 411.

[0118] Therefore, the setting angles of the solid discharging power 411 and the liquid discharging power 412 are the same as the angles of the discharging ports 32 of the two sub-fan-shaped unit boxes 33 .

[0119] In this embodiment, the adjustment of the lead screw 63 is limited to one adjustment at the beginning according to the density of the seasoning, and no adjustment is required in the future, and only the discharge control is required. After the density of the solid seasoning is determined each time the seasoning is added, the corresponding quantitative accuracy adjustment is performed. If the solid seasoning always uses the same brand, it only needs to be adjusted once. If the solid seasoning changes brands, it is readjusted according to the density of different brands.

[0120] According to the laboratory data of Beijing University of Architecture, the bulk density of different solid seasonings ranges from 0.7 to 1.1 g / cm 3 The density of liquid seasoning is between 0.9-1.3g / cm 3 The relevant seasoning density is shown in Table 1.

[0125] The bidirectional driving mechanism 23 is connected to the inner wall of the outer shell 1, and has a driving gear 231 respectively meshing with the upper tooth pattern 241 and the lower tooth pattern 251. When the driving gear 231 rotates, the upper annular toothed disc 24 and the lower annular toothed disc 25 rotate in different directions, and the upper driving disc 21 and the lower driving disc 22 can only be driven to rotate in one rotation direction by the corresponding upper annular toothed disc 24 and the lower annular toothed disc 25 under the action of the elastic wedge-shaped portion 26, and the upper driving disc 21 and the lower driving disc 22 can be driven to rotate in opposite directions.

[0126] In order to further optimize the above technical solution, the elastic wedge-shaped portion 26 includes a wedge block 261 and a spring 262; a wedge-shaped portion slide groove 263 is provided on the outer circumferential wall of the upper annular gear plate 24 and the lower annular gear plate 25, and the wedge block 261 is slidably connected in the wedge-shaped portion slide groove 263; the spring 262 is arranged in the wedge-shaped portion slide groove 263 and is connected between the bottom surface of the wedge-shaped portion slide groove 263 and the wedge block 261.

[0127] In order to further optimize the above technical solution, the inclined surface of the wedge-shaped head 2611 is processed into an outwardly convex arc surface 2612.

[0128] See attached Figure 6 The outer circumferential wall surfaces of the upper driving disk 21 and the lower driving disk 22 are both provided with elastic marbles 265 , and the inner wall of the outer shell 1 is provided with limiting grooves 266 corresponding to the elastic marbles 265 .

[0129] In order to further optimize the above technical solution, the bidirectional driving mechanism 23 includes a bidirectional driving motor 232 , the casing of the bidirectional driving motor 232 is fixed on the inner wall of the outer shell 1 , and the power output shaft of the bidirectional driving motor 232 is fixed to the driving gear 231 .

[0130] In order to further optimize the above technical solution, the number of the fan-shaped seasoning unit boxes 3 is the same as the number of the elastic wedge-shaped portions 26 arranged on the upper driving disk 21 and the lower driving disk 22, and the multiple elastic wedge-shaped portions 26 correspond to the multiple fan-shaped seasoning unit boxes 3 respectively.

[0131] See attached Fig.19 and attached Fig. 20 The solid discharging power 411 includes a solid discharging motor 4111 and a solid discharging straight-line rotating shaft 4112; the liquid discharging power 412 includes a liquid discharging vibration motor 4121 and a liquid discharging straight-line rotating shaft 4122; and the regulating power source 42 includes an regulating motor 421 and a regulating straight-line rotating shaft 422. It should be noted that in order to achieve size adjustment, the regulating motor 421 is a bidirectional motor that can achieve rotation in different directions.

[0132] In this embodiment, a central axis 211 is fixed at the center of the bottom surface of the upper driving disk 21, and a through hole 221 is provided at the center of the lower driving disk 22 to avoid the central axis 211. The driving unit 4 is installed at the bottom end of the central axis 211. The bottom end of the central axis 211 is rotatably connected to the fixed rod of the seasoning box linear telescopic rod 1331. The bottom end of the central axis 211 has three radially extending driving mounting rods 2111, and the three driving mounting rods 2111 are respectively installed with a solid discharging motor 4111, a liquid discharging vibration motor 4121 and an adjusting motor 421; the power output end of the solid discharging motor 4111 is connected to the solid discharging straight-line rotating shaft 4112, the power output end of the liquid discharging vibration motor 4121 is connected to the liquid discharging straight-line rotating shaft 4122, and the power output end of the adjusting motor 421 is connected to the adjusting straight-line rotating shaft 422. The setting angles of the three driving mounting rods 2111 are as shown in FIG. Fig.21 and Fig. 22 As shown, it can meet the coupling with the corresponding position that needs to be driven during the rotation process. In addition, the three drive mounting rods 2111 need to have upper and lower position avoidance to prevent position interference.

[0133] It should be noted that, for every 180° rotation of the solid discharging straight-line rotating shaft 4112 , 1 g of solid is discharged, that is, the amount of solid inside each sector-shaped quantitative cavity 623 is set to 0.5 g.

[0134] See attached Fig.34 The liquid inlet pipe 71 of the negative pressure suction pump 7 is connected to the discharge port, and the liquid discharge pipe 72 faces downward. The power end of the negative pressure suction pump 7 has a liquid discharge straight groove 73. After the liquid discharge straight shaft 4122 is inserted, the liquid discharge vibration motor 4121 discharges liquid by vibration. Each vibration will compress a certain volume, and each compression is 0.5cm 3 The volume of the gas is calculated, then the volume of the liquid discharged each time will be 0.5cm 3At the same time, combining the density of the liquid seasoning already in the system with the volume of the liquid seasoning required by the user, according to the density formula ρ=m / V, the required liquid volume can be obtained, and the required liquid volume is divided by the gas volume compressed each time to obtain the number of vibrations of the liquid discharge vibration motor 4121. Through system control, the required amount of liquid seasoning can be obtained.

[0135] In order to detect the amount of seasoning in the fan-shaped seasoning unit box 3, the present embodiment further adds an ultrasonic sensor 27. A radially extending detection mounting rod 2112 is arranged on the upper part of the central axis 211, that is, in the middle of the upper driving disk 21 and the lower driving disk 22. The ultrasonic sensor 27 is installed on the detection mounting rod 2112. The lower driving disk 22 is provided with a detection hole 223 corresponding to the fan-shaped seasoning unit box 3. When the fan-shaped seasoning unit box 3 rotates, the depth of the seasoning inside it can be detected, and then it can be determined whether it needs to be added.

[0136] The conductive wires of the ultrasonic sensor 27 and each motor of the driving unit 4 are connected to the circuit board through the center shaft 211 .

[0137] After each seasoning is completed, the lower drive disc 22 rotates and resets, or the system retains the position information of this time to provide a standard for the next start.

[0138] In this embodiment, the intelligent control layer 11 further includes: a display screen 111 for displaying an interface, and a touch panel 112 for an operator to use.

[0139] In this embodiment, the display screen 111 is used to display information, and the touch panel 112 is used for operator interaction. The circuit board is used to integrate various functional control modules, mainly including:

[0140] Central Processing Unit (CPU): The central processing unit is used to receive signals and control the output of signals.

[0141] Information storage module: used to store information about dishes, i.e., what seasonings are needed for a certain dish, and the amount of seasonings corresponding to the number of people eating. The information storage module can be factory-provided information content, or it can be entered by the user through the interaction of the touch panel 112 and the display screen 111 according to the user's usage requirements.

[0142] When the operator selects the dish to be prepared through the touch panel 112, the information storage module transmits the corresponding dish information to the central processor, and the central processor controls the rotation of the bidirectional drive motor 232, and the bidirectional drive motor 232 controls the rotation of the lower drive disk 22. In this embodiment, the number of rotations of the drive gear 231 is set to the corresponding position correspondence, such as 5 rotations of the drive gear 231, which is 72°, that is, the standard position of each fan-shaped seasoning unit box 3. In this way, by rotating the drive gear 231, the corresponding fan-shaped seasoning unit box 3 that needs to be discharged is adjusted to align with the receiving box 5, and then the corresponding solid discharge motor 4111 and liquid discharge vibration motor 4121 are controlled to start discharging. The solid discharge straight-line shaft 4112 of the solid discharge motor 4111 rotates different numbers of times, corresponding to different grams, and the liquid discharge vibration motor 4121 vibrates different times, corresponding to different capacities.

[0143] After the discharge is completed, the bidirectional drive motor 232 controls the lower drive disk 22 to rotate and reset. A corresponding infrared sensing element can be set inside to facilitate reset. In this embodiment, the information storage module records the position of the information input, and finally resets. The infrared sensing element is set in a conventional structure, that is, it can be set between the non-rotating body and the rotating body. In the present invention, it can be set on the outer shell 1 and any rotating structure inside it. It is a conventional structural feature and will not be repeated here.

[0144] When the seasoning is discharged, the linear track pop-up mechanism 141 of the material receiving box is started, driving the material receiving box pop-up door 142 and the material receiving box 5 to pop out, and the operator can take it. After taking it and putting it back, the linear track pop-up mechanism 141 of the material receiving box drives the material receiving box pop-up door 142 and the material receiving box 5 to be retracted.

[0145] The information storage module provided in this embodiment is also used to store the above-mentioned seasoning density information. When switching different seasonings, the central processor controls the rotation of the bidirectional drive motor 232, and the bidirectional drive motor 232 controls the rotation of the upper drive disk 21. That is, the central shaft 211 is driven to rotate, and the capacity of the fan-shaped quantitative cavity 623 is adjusted by turning the lead screw 63 by the adjusting motor 421. It should be noted that before the solid and liquid are discharged after the first loading, the solid discharge motor 4111 of the solid discharge part needs to be rotated 180° first, and the liquid discharge vibration motor 4121 needs to vibrate three times first. The operator needs to judge whether the machine is discharging normally by whether there is seasoning for compensation in the receiving box 5, and finally dispose of it.

[0146] During the rotation of the lower driving disk 22, the ultrasonic sensor 27 on the detection mounting rod 2112 detects the depth inside the fan-shaped seasoning unit box 3, and then determines whether the seasoning inside is sufficient. If not, it is fed back to the central processor to alarm.

[0147] When it is necessary to add seasoning, the seasoning box linear track pop-up mechanism 133 drives the fan-shaped seasoning unit box pop-up door 132 and the fan-shaped seasoning unit box 3 that needs to be replenished to pop out, and the adding operation can be carried out. After the adding is completed, the seasoning box linear track pop-up mechanism 133 drives the fan-shaped seasoning unit box pop-up door 132 and the replenished fan-shaped seasoning unit box 3 to be retracted.
