Description

Technical Field

[0001] This invention relates to a hot food vending machine, and more particularly to an energy-saving hot food vending machine with photothermal energy circulation, belonging to the field of hot food vending technology. Background Technology

[0002] Automated vending machines, due to their ability to automate the transaction of goods, are not limited by time or location and can operate 24 hours a day. Compared with the traditional manual sales model, they significantly reduce labor costs and lower the requirements for production and operation sites, and have a wide range of applications in the market. They are mainly deployed in densely populated areas such as bus stations, airports, schools, hospitals and other public places.

[0003] For example, application number 202011015729.8 is the closest prior art. The prior art discloses a cabinet, a shelf, a microwave oven heating device, a rotating delivery device, and a receiving device. The cabinet has a left door and a right door that are rotatably installed. The shelf holds seasoning packets. The microwave oven heating device includes a bracket and a microwave oven body. The bottom of the microwave oven body has an opening. The receiving device includes a microwave oven door, a sliding rack, and a drive device. The drive device drives and controls the microwave oven door to move in the horizontal and vertical directions. After the microwave oven door rises, it can seal the opening at the bottom of the microwave oven body. The sliding rack can slide linearly between the rotating delivery device and the microwave oven body. The rotating delivery device includes a water injection device. The piercing tube on the water injection device moves downward to pierce and inject water into the packaging of boxed or bagged food.

[0004] In the prior art, when the rotary dispensing device 2 dispenses goods, the rotary motor works and drives the rotary disk to rotate. When the longitudinal aisle containing the required boxed or bagged food rotates to the designated position, the rotary motor stops rotating. The picking mechanism can then pick up the boxed or bagged food from the longitudinal aisle and transport it to the dispensing port. The picking structure in the prior art is not convenient for flexibly lifting and moving goods laterally for different shelf levels and different directions. The existing shelving has an inclined structure with baffles installed at the outer end to prevent it from falling off. It replenishes goods according to the degree of inclination. This can cause the edges and corners of the goods to get caught on the sides of the shelving during the inclined replenishment process, which may cause jamming or stop replenishment. The existing power supply structure uses a power cord to connect the cabinet and the power input line to provide power, and the cumbersome internal structure leads to high energy consumption.

[0005] Therefore, an energy-saving hot food vending machine with photothermal energy circulation is needed to improve the above-mentioned shortcomings. Summary of the Invention

[0006] The main objective of this invention is to provide an energy-saving hot food vending machine with photothermal energy circulation.

[0007] The objective of this invention can be achieved by adopting the following technical solution: An energy-saving hot food vending machine with photothermal energy circulation includes a cabinet for installing equipment.

[0008] Preferably, a solar energy collection device is installed on the top of the cabinet. The solar energy collection device consists of a lower push rod, a second solar panel, a third solar panel, a first solar panel, an upper push rod, a lower extension guide rail, an upper extension guide rail, and a sunlight sensor. The solar energy collection device is equipped with sunlight sensors at its four corners, and an upper extension guide rail and a lower extension guide rail are obliquely and symmetrically installed on its inner side from top to bottom; A push rod is installed on one side of the bottom of the first solar panel, and the output end of the push rod is connected to the second solar panel. A push rod is installed at the bottom of the second solar panel, and the output end of the push rod is connected to the third solar panel. The solar panel 2, solar panel 3, upper push rod, and lower push rod are an alternating superimposed structure.

[0009] Preferably, the second solar panel can be pushed outward along the upper extension guide rail, and the third solar panel can be pushed outward along the lower extension guide rail.

[0010] Preferably, a power supply box is installed on the upper transverse partition inside the sealing plate, an upper outlet synchronous belt conveyor assembly is installed on the transverse partition at the bottom of the power supply box, a microwave oven heating cavity assembly is installed on the transverse partition at the bottom of the upper outlet synchronous belt conveyor assembly, and a push drive component is installed on the transverse partition at the bottom of the microwave oven heating cavity assembly.

[0011] Preferably, the power supply box and the solar energy collection device are connected by a power supply line.

[0012] Preferably, the shelf has a sliding groove, and a push plate is provided in the sliding groove. The push plate is connected by a spring, and at least one set of shelves is placed horizontally and vertically.

[0013] Preferably, an upper outlet synchronous belt conveyor assembly is installed in the middle section of the inner side of the sealing plate. This assembly consists of a conveyor belt, a fixed frame, a conveyor drive component, a main rotating rod, and an auxiliary rotating rod. The sealing plate has symmetrically installed fixing frames on the transverse partition in the middle of its inner side. The fixing frames have symmetrically arranged main rotating rods and auxiliary rotating rods on both sides, and conveyor belts are fitted on the main rotating rods and auxiliary rotating rods. A conveying drive component is installed at one end of the main rotating rod. The conveying drive component is fixedly connected to the fixed frame, and the conveying drive component drives the main rotating rod, the auxiliary rotating rod, and the conveyor belt to move together.

[0014] Preferably, the microwave oven heating cavity assembly is connected to a waste heat recovery component on the outside, which consists of a diversion pipe, a heat collection fan, a filter, an exhaust port, a battery pack box, and a thermoelectric generator. The waste heat recovery unit is symmetrically equipped with thermoelectric generators at one end and a heat collection fan at the other end. A filter element is installed inside the diversion pipe, and the diversion pipe is connected to the heat collection fan.

[0015] Preferably, a push plate is installed at the output end of the push drive component, a push plate fixing frame is installed at the bottom of the inner side of the sealing plate, and the push drive component is fixedly installed on the top of the push plate fixing frame.

[0016] Beneficial technical effects of the present invention: The cabinet is divided into a symmetrical space with narrowing in the middle by vertical partitions. Horizontal partitions are installed between the two sets of vertical partitions, providing integrated installation space for the power supply box, the synchronous belt conveyor components at the top loading port, the push drive, and the microwave oven heating cavity components. This layout forms an efficient architecture of "storage on both sides and integration in the middle". The two sides focus on storage, while the middle coordinates power supply, heating, heat collection, and loading functions, allowing the various systems to work together and achieving dual optimization of space utilization and functional integration. Meanwhile, the lifting robotic arm assembly configured on the corresponding side of the cabinet and the vertical partition can precisely drive the delivery transmission mechanism to complete the lifting action. During the lifting process, the picking component on the transmission mechanism simultaneously slides laterally. After moving to the target position to complete the picking, the picking component is then moved along the transmission mechanism to the conveying cavity to smoothly export the goods. This application realizes a multi-faceted and multi-level cyclical pickup system, which allows pickup operations to flexibly cover different areas and levels, ensuring that the whole process is coherent, efficient and orderly.

[0017] This application adopts a structure that integrates solar energy and protection mechanism. When the sun first appears and the equipment is put into use, the push rod will precisely drive the second and third solar panels to extend outward. This unfolding process cleverly expands the solar energy collection area, allowing the equipment to capture light energy more efficiently and improve energy conversion efficiency. When the sun sets and darkness falls, and the equipment enters a static state, the push rod is activated again, causing the two solar panels to retract inward. This application not only provides thoughtful protection for solar panel two and solar panel three, avoiding potential damage caused by nighttime environments, but its compact storage design also makes the overall device more simple and practical.

[0018] The design of the shelving cleverly realizes the adaptive pushing structure of goods. When goods are stacked on the shelving, the push plate will slide smoothly inward along the sliding groove until it reaches the end of the shelving and the sliding groove, thus completing the temporary storage of goods. When the goods at the outer end of the shelf are taken away, the spring in the sliding groove will release the stored elasticity, pushing the push plate to move outward smoothly. During this process, the push plate will push the remaining goods outward. With the help of the continuous and moderate thrust of the spring, the problem of goods getting stuck due to accidental snagging on the sides of the shelf when moving outward can be effectively avoided, which may even interrupt the replenishment process, so that the replenishment of goods can always be smooth and efficient.

[0021] To enable those skilled in the art to understand the technical solution of the present invention more clearly, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0022] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11, Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 , Figure 18 , Figure 19 As shown, this embodiment provides an energy-saving hot food vending machine with photothermal energy circulation, including a cabinet 1 for installing equipment. The cabinet 1 has a door 105 that opens and closes on one side. A sealing plate 106 is installed in the middle of the cabinet 1. Horizontal partitions 206 are distributed horizontally on the inner side of the sealing plate 106. Vertical partitions 207 are symmetrically installed on both sides of the horizontal partitions 206. A conveying cavity 205 is opened on the vertical partitions 207. Shelves 7 are distributed between the cabinet 1 and the vertical partitions 207. A lifting mechanical arm assembly 5 is symmetrically installed between the cabinet 1 and the vertical partition 207, and a delivery transmission mechanism 6 is lifted and installed on the lifting mechanical arm assembly 5. The lifting mechanical arm assembly 5 is fixedly connected to both sides of the cabinet 1 through the cabinet connector 501. The lifting mechanical arm assembly 5 is symmetrically provided with a lifting synchronous conveyor belt device 502 for lifting. A clamping plate 612 is installed on the lifting synchronous conveyor belt device 502. A delivery transmission mechanism 6 is fixedly installed on the clamping plate 612. Guide rails 611 are symmetrically installed on both sides of the delivery transmission mechanism 6. The lifting mechanical arm assembly 5 drives the delivery transmission mechanism 6 to run vertically. The delivery transmission mechanism 6 is equipped with a synchronous transmission device 601. One end of the synchronous transmission device 601 is equipped with a transmission drive component 603. The output end of the transmission drive component 603 is equipped with a drive rod 604. A main transmission wheel 606 is sleeved on the drive rod 604. An auxiliary transmission wheel 607 is installed at a position flush with the outer side of the main transmission wheel 606. A conveyor belt 605 is sleeved on the main transmission wheel 606 and the auxiliary transmission wheel 607. The guide rail 611 is equipped with a connecting robotic arm 602 that can move left and right. A robotic arm connecting plate 610 is installed on the top of the connecting robotic arm 602. A motor 609 is installed on the top of the robotic arm connecting plate 610. A lunch box insert 608 is provided at the output end of the motor 609. The synchronous conveying device 601 drives the connecting robotic arm 602 and the robotic arm connecting plate 610 to run horizontally. like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16, Figure 17 , Figure 18 , Figure 19 As shown, the main body of cabinet 1 is first constructed. After ensuring the stability of the cabinet structure, cabinet door 105 is installed on one side of cabinet 1 using hinges or opening and closing connectors to ensure that cabinet door 105 can open and close smoothly and achieve internal sealing when closed. A sealing plate 106 is fixedly installed in the middle of the interior of cabinet 1. With sealing plate 106 as the center reference, horizontal partitions 206 are evenly distributed and fixed on its inner side. The horizontal partitions 206 must be kept horizontal to ensure that subsequent components are installed flat. Vertical partitions 207 are symmetrically installed on both sides of the horizontal partitions 206. The vertical partitions 207 must be vertically connected to the horizontal partitions 206. A conveying cavity 205 is opened on the vertical partitions 207 at the position corresponding to the subsequent picking path. The size of the conveying cavity 205 must match the requirements of lunch box conveying. Finally, shelves 7 are placed in the gap area between cabinet 1 and vertical partitions 207. The shelves 7 must correspond to the positions of horizontal partitions 206 and vertical partitions 207 to ensure that the shelves 7 are stable and do not affect the operation of subsequent mechanical components. A synchronous conveying device 601 is installed in the internal frame of the delivery transmission mechanism 6. The transmission direction of the synchronous conveying device 601 must be parallel to the guide rail 611, that is, it is set in the transverse direction. A transmission drive 603 is fixedly installed at one end of the synchronous conveying device 601. The output end of the transmission drive 603 is connected to the drive rod 604 to ensure that the drive rod 604 can rotate under the drive of the transmission drive 603. The main drive wheel 606 is sleeved and fixed on the drive rod 604. An auxiliary conveying wheel 607 is installed at a position flush with the outer side of the main drive wheel 606. Then, a conveyor belt 605 is sleeved on the main drive wheel 606 and the auxiliary conveyor wheel 607. The tension of the conveyor belt 605 is adjusted to ensure smooth transmission. The left-right movable connecting robotic arm 602 is embedded in the guide rail 611 to ensure that the connecting robotic arm 602 can slide smoothly along the guide rail 611; the robotic arm connecting plate 610 is installed on the top of the connecting robotic arm 602, and the robotic arm connecting plate 610 must be kept horizontal; finally, the motor 609 is fixedly installed on the top of the robotic arm connecting plate 610, and the lunch box inserter 608 is installed on the output end of the motor 609. The rotation angle and force of the motor 609 are adjusted to ensure that the lunch box inserter 608 can stably insert, pick up and release lunch boxes; Upon receiving the pickup instruction, the system first locates the shelf level 7 and horizontal position of the target lunchbox. Then, the lifting robotic arm assembly 5 is activated, driving the clamping plate 612 and delivery transmission mechanism 6 vertically via the lifting synchronous conveyor belt device 502 until the delivery transmission mechanism 6 is aligned with the shelf level 7 of the target lunchbox. The synchronous conveyor device 601 within the delivery transmission mechanism 6 then activates, moving the connecting robotic arm 602 along the guide rail 611 towards the horizontal position of the target lunchbox. When the lunchbox insert 608 moves directly in front of the target lunchbox, the synchronous conveyor device 601 pauses operation, and the motor... 609 is activated, driving the lunchbox inserter 608 to rotate or extend, so that the lunchbox inserter 608 inserts into the preset slot of the lunchbox or clamps the lunchbox, completing the picking action. After picking is completed, the synchronous conveying device 601 runs in reverse, driving the connected robotic arm 602 and the lunchbox inserter 608 holding the lunchbox to move along the guide rail 611 towards the conveying chamber 205 of the vertical partition 207. When the lunchbox moves to the corresponding position in the conveying chamber 205, the motor 609 drives the lunchbox inserter 608 to release the lunchbox. The lunchbox enters the subsequent conveying or heating stage through the conveying chamber 205, thus completing a single picking step. The cabinet 1 is divided into a symmetrical space with narrowing in the middle by vertical partitions 207. Horizontal partitions 206 are installed between the two sets of vertical partitions 207, providing integrated installation space for the power supply box 3, the upper loading port synchronous belt conveyor assembly 4, the push drive component 9, and the microwave oven heating cavity assembly 11. This layout forms an efficient architecture of "storage on both sides and integration in the middle". The two sides focus on storage, while the middle coordinates power supply, heating, heat collection and loading functions, allowing the various systems to work together and achieving dual optimization of space utilization and functional integration. Meanwhile, the lifting mechanical arm assembly 5, which is configured on the corresponding side of the cabinet 1 and the vertical partition 207, can precisely drive the delivery transmission mechanism 6 to complete the lifting action. During the lifting process, the picking component on the transmission mechanism slides laterally. After moving to the target position to complete the picking, the picking component is then moved along the transmission mechanism to the conveying chamber 205 to smoothly export the goods. This application realizes a multi-faceted and multi-level cyclical pickup system, which allows pickup operations to flexibly cover different areas and levels, ensuring that the whole process is coherent, efficient and orderly.

[0023] Example 2: The solution in Example 1 will be further described below with reference to its specific working method. See the description below for details: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 Figure 7 , Figure 8 , Figure 9 , Figure 10, Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 , Figure 18 , Figure 19 As shown, as a preferred embodiment, based on the above method, the top of the cabinet 1 is further equipped with a solar energy collection device 2, which consists of a lower push rod 201, a second solar panel 202, a third solar panel 203, a first solar panel 204, an upper push rod 208, a lower extension guide rail 209, an upper extension guide rail 210, and a sunlight sensor 211. The solar energy collection device 2 has a sunlight sensor 211 installed at each of its four corners, and an upper extension guide rail 210 and a lower extension guide rail 209 are installed obliquely and symmetrically from top to bottom on its inner side. An upper push rod 208 is installed on one side of the bottom of the first solar panel 204. The output end of the upper push rod 208 is connected to the second solar panel 202. A lower push rod 201 is installed at the bottom of the second solar panel 202. The output end of the lower push rod 201 is connected to the third solar panel 203. The solar panel 202, solar panel 203, upper push rod 208 and lower push rod 201 are in an alternating superimposed structure; The second solar panel 202 can be pushed outward along the upper extension guide rail 210, and the third solar panel 203 can be pushed outward along the lower extension guide rail 209; like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 , Figure 18 , Figure 19As shown, in a preferred embodiment, based on the above method, the solar collector 2 is first fixed to the preset installation position on the top of the cabinet 1 by bolts or welding to ensure that the solar panel 204 is tightly attached to the top surface of the cabinet 1, the structure is stable and there is no shaking. Taking the solar panel 204 as the reference, the upper extension guide rail 210 and the lower extension guide rail 209 are installed on the inner side of the solar collector 2 near the center of the cabinet according to the principle of "oblique symmetry from top to bottom". The tilt angle of the upper extension guide rail 210 needs to match the push-out path of the solar panel 202, and the tilt angle of the lower extension guide rail 209 needs to match the push-out path of the solar panel 203. The two sets of guide rails need to be parallel to the length direction of the solar collector 2 to avoid subsequent sliding jamming. At the bottom side of solar panel 204, near the corresponding position of the upper extension guide rail 210, a connecting rod 208 is fixedly installed using a connector, ensuring that the axial direction of the upper push rod 208 is consistent with the tilt direction of the upper extension guide rail 210. One end of solar panel 202 is connected to the output end of the upper push rod 208 via a hinge or snap-fit, while the bottom edge of solar panel 202 is embedded in the groove of the upper extension guide rail 210. When the upper push rod 208 extends or retracts, solar panel 202 can slide smoothly along the upper extension guide rail 210. At the bottom of solar panel 202, near the corresponding position of the lower extension guide rail 209, a connecting rod is also installed... Fixed installation of the lower push rod 201, ensuring that the axial direction of the lower push rod 201 is consistent with the tilt direction of the lower extension guide rail 209. Connect one end of the solar panel 203 to the output end of the lower push rod 201, and simultaneously embed the bottom edge of the solar panel 203 into the groove of the lower extension guide rail 209. At this time, the positions of the three sets of solar panels need to be adjusted to ensure that the solar panel 202, the solar panel 203, the upper push rod 208, and the lower push rod 201 form an "interlaced superposition structure". That is, when not unfolded, the solar panel 203 is stacked below the solar panel 202, and the solar panel 202 is stacked below the solar panel 204, with no component interference. At the four corners of the solar collector 2, corresponding to the east, south, west, and north directions respectively, the sunlight sensor 211 is fixedly installed with screws to ensure that the detection surface of the sensor faces the sky and is unobstructed; at the same time, the signal line of the sunlight sensor 211 is connected to the control system of the vending machine to complete the transmission link of the detection signal. The sunlight sensor 211 collects the light intensity and light angle data in the environment in real time and transmits the data to the main control system of the vending machine. The upper push rod 208 is activated first, with its output end extending outward to push solar panel 202 to slide outward along the inclined direction of the upper extension guide rail 210 until solar panel 202 is fully extended to a length not exceeding the width of cabinet 1 and without any collision of parts. After a synchronous or delayed period of 1 to 2 seconds, the lower push rod 201 is activated, with its output end extending outward to push solar panel 203 to slide outward along the inclined direction of the lower extension guide rail 209 until solar panel 203 is fully extended. At this time, the three sets of solar panels form a "stepped unfolding structure", which greatly expands the light collection area and improves the light energy conversion efficiency. If the light on the east side weakens and the light on the west side strengthens, the upper push rod 208 fine-tunes the extension length of solar panel 202, with the west end slightly longer and the east end slightly shorter. The lower push rod 201 simultaneously fine-tunes solar panel 203, so that the light-collecting surface of the two sets of solar panels always faces the direction of the strongest light, avoiding excessive movement that could lead to structural instability. The lower push rod 201 first reverses direction, retracts its output end, and pulls the third solar panel 203 inward along the lower extension guide rail 209 until the third solar panel 203 is completely stacked under the second solar panel 202. After a synchronous or delayed period of 1 to 2 seconds, the upper push rod 208 reverses direction, retracts its output end, and pulls the second solar panel 202 inward along the upper extension guide rail 210 until the second solar panel 202 is completely stacked under the first solar panel 204. Finally, the "staggered stacking structure" is restored, reducing the erosion of the solar panels by external dust and rainwater, while also reducing the structural space occupied in the non-working state.

[0024] This application adopts a structure that integrates solar energy and protection mechanism. When the sun first appears and the device 1 is put into use, the push rod 201 will precisely drive the solar panel 202 and the solar panel 203 to extend outward. This unfolding process cleverly expands the solar energy collection area, allowing the device to capture light energy more efficiently and improve energy conversion efficiency. When the sun sets and darkness falls, and the equipment enters a static state, push rod 201 is activated again, causing the two solar panels to retract inward. This application not only provides thoughtful protection for solar panel 202 and solar panel 203, avoiding potential damage caused by nighttime environments, but its compact storage design also makes the overall device more simple and practical.

[0025] Example 3: The solutions in Examples 1 and 2 will be further described below with reference to their specific working methods. See the description below for details: like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in a preferred embodiment, based on the above method, a power supply box 3 is installed on the transverse partition 206 above the inner side of the sealing plate 106, an upper outlet synchronous belt conveyor assembly 4 is installed on the transverse partition 206 at the bottom of the power supply box 3, a microwave oven heating cavity assembly 11 is installed on the transverse partition 206 at the bottom of the upper outlet synchronous belt conveyor assembly 4, and a push drive component 9 is installed on the transverse partition 206 at the bottom of the microwave oven heating cavity assembly 11. The power supply box 3 and the solar energy collection device 2 are connected by a power supply line 301; like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the inner side of the positioning sealing plate 106 pushes the horizontal partition 206 directly above the drive component 9. Clean the impurities on the surface of the horizontal partition 206 to ensure that the installation surface is flat. Place the microwave oven heating cavity assembly 11 in the preset area of ​​the horizontal partition 206. Adjust the position of the assembly so that the bottom outlet of the microwave oven heating cavity assembly 11 is aligned with the moving path of the push plate 901 below to ensure that the push plate 901 can smoothly push the heated food box. Use L-shaped angle steel or fastening screws to fix the bottom of the microwave oven heating cavity assembly 11 to the horizontal partition 206. The fixing points should be evenly distributed at least 4 fixing points, located at the four corners of the assembly, to prevent the assembly from shaking during operation. Connect the control lines of the microwave oven heating cavity assembly 11, such as temperature control and door opening and closing control. Connect the control lines to the main control system inside the cabinet 1. Test whether the heating function and door opening and closing function of the assembly are normal to ensure that the heating temperature meets the standard and the operation is stable. The uppermost horizontal partition 206 inside the positioning sealing plate 106 corresponds to the layer above the synchronous belt conveyor assembly 4 at the shipping port. At the power box installation position reserved on the horizontal partition 206, place the power box 3, adjust the position of the power box 3 so that the wiring port of the power box 3 faces the top of the cabinet 1 to facilitate the subsequent connection of the power supply line 301 of the solar energy collection device 2, and ensure that the heat dissipation holes on the side of the power box 3 are not obstructed. Fix the bottom of the power box 3 to the horizontal partition 206 with fastening screws. When fixing, ensure that the power box 3 is not tilted to avoid uneven stress on the internal electrical components. Open the cabinet door of power supply box 3 and check the installation status of internal components such as the battery, inverter, and terminals to ensure they are not loose. Then connect the internal control lines of power supply box 3, such as charge / discharge control and overload protection control. Connect the control lines to the main control system and test whether the standby state of power supply box 3 is normal. Close the main switch of power supply box 3 and start the main control system. Enter the "Solar Power Supply Monitoring" interface and check the output voltage and current data of solar collector 2 to confirm whether power supply box 3 is receiving solar power normally. Test the charging and discharging function of power supply box 3. If there is sufficient solar light, observe the charging status of the battery inside power supply box 3. The charging indicator light should be constantly on. If the solar collector 2 is blocked, simulate a no-light state and observe whether power supply box 3 automatically switches to battery power supply and whether all electrical components, such as drive component 9 and microwave oven heating cavity assembly 11, can still operate normally. Simulate high-load conditions through the main control system, such as simultaneously starting the lifting robotic arm assembly 5 and microwave oven heating cavity assembly 11, and check whether the overload protection device of power supply box 3 can automatically cut off the power when the current exceeds the rated value to ensure system safety.

[0026] Example 4: The solutions in Examples 1, 2, and 3 will be further described below with reference to their specific working methods. See the description below for details: like Figure 3 As shown, in a preferred embodiment, based on the above method, the shelf 7 is further provided with a sliding groove 701, and a push plate 702 is provided in the sliding groove 701. The push plate 702 is pushed and connected by a spring 703, and at least one set of shelves 7 is placed horizontally and vertically.

[0027] like Figure 3 As shown, the design of shelf 7 cleverly realizes the adaptive pushing structure of goods. When goods are stacked on the shelf, push plate 702 will slide smoothly inward along sliding groove 701 until it reaches the end of shelf 7 and sliding groove 701, thus completing the temporary storage of goods. When the goods at the outer end of the shelf are taken away, the spring 703 in the sliding groove 701 will release the stored elastic force, pushing the push plate 702 to move outward smoothly. During this process, the push plate will push the remaining goods outward. With the help of the continuous and moderate thrust of the spring, the corners of the goods can be effectively prevented from getting stuck on the sides of the shelf when the goods are moved outward, which may even cause the replenishment process to be interrupted, so that the replenishment of goods can always be smooth and efficient. Example 5: The solutions in Examples 1, 2, 3, and 4 will be further described below with reference to their specific working methods. See the description below for details: like Figure 16 and Figure 17As shown, in a preferred embodiment, based on the above method, a top outlet synchronous belt conveyor assembly 4 is further installed in the middle section of the inner side of the sealing plate 106. The assembly consists of a conveyor belt 401, a fixing frame 402, a conveyor drive component 403, a main rotating rod 404, and an auxiliary rotating rod 405. A fixing frame 402 is symmetrically installed on the transverse partition 206 in the middle section of the inner side of the sealing plate 106. A main rotating rod 404 and an auxiliary rotating rod 405 are symmetrically arranged on both sides of the fixing frame 402. A conveyor belt 401 is sleeved on the main rotating rod 404 and the auxiliary rotating rod 405. One end of the main rotating rod 404 is equipped with a conveying drive component 403. The conveying drive component 403 is fixedly connected to the fixed frame 402, and the conveying drive component 403 drives the main rotating rod 404, the auxiliary rotating rod 405 and the conveyor belt 401 to move together. like Figure 16 and Figure 17 As shown, the main rotating rod 404 and the auxiliary rotating rod 405 are respectively installed into the bearing seats / shaft holes on both sides of the fixed frame 402, ensuring that the main rotating rod 404 and the auxiliary rotating rod 405 are installed in the same direction, and that the exposed lengths at both ends are symmetrical. There should be no jamming or abnormal noise when rotating, and the flexibility can be tested by hand rotation. The drive connection end of the main rotating rod 404 is reserved to connect with the conveyor drive component, ensuring that it faces the preset assembly direction. Lay the conveyor belt 401 flat and place it on the outside of the main rotating rod 404 and the auxiliary rotating rod 405 in sequence. Adjust the position of the conveyor belt 401 to ensure that it covers the effective transmission surface of the main and auxiliary rotating rods without any offset or wrinkles. The conveyor belt 401 can be appropriately tensioned by adjusting the spacing of the fixing frame or the axial position of the rotating rod. It will rebound immediately after being released, with no risk of slippage. Connect the output shaft of the conveyor drive 403 to the drive connection end of the main rotating rod 404 using a key connection, coupling, or set screw. Adjust the installation posture of the conveyor drive 403 according to the design structure to make its housing fit the preset mounting surface of the fixing frame 402. Fix the conveyor drive 403 to the fixing frame 402 with fasteners. Check the drive connection part again to ensure that the connection is firm, without looseness or coaxiality deviation. Turn on the power supply or test power source of the conveyor drive 403 and start the drive. The main rotating rod 404 drives the conveyor belt 401 to rotate, and the auxiliary rotating rod 405 rotates synchronously with the conveyor belt. There is no jamming, deviation, or slippage. The drive unit is turned off, and the main rotating rod 404 is manually rotated to verify the smoothness of the linkage between the conveyor belt and the auxiliary rotating rod, and to confirm that there is no abnormal resistance.

[0028] Example 6: The solutions in Examples 1, 2, 3, 4, and 5 will be further described below with reference to their specific working methods. See the description below for details: like Figure 16As shown, in a preferred embodiment, based on the above method, the microwave oven heating cavity assembly 11 is further connected to a waste heat recovery component 8 on the outside.

The push drive component 9 is fixedly installed on the top of the push plate fixing frame 902. like Figure 16 As shown, smoothly place the filter element 803 into the preset installation position inside the diversion pipe 801, ensuring that the filter element fits tightly against the inner wall of the diversion pipe without any loose gaps. The diversion pipe is connected to the heat collector fan. Align one end of the diversion pipe 801 with the filter element 803 assembled with the connection interface of the heat collector fan 802, and fix it with preset connectors such as clips, threads, or sealant to ensure a good seal at the connection and no air leakage. Install the components at both ends of the waste heat recovery component 806. Symmetrically install the thermoelectric generator 806 at one end of the waste heat recovery component 806, ensuring that the two generators are installed in parallel positions and are firmly fixed. After confirming that the electrode interfaces are aligned and that the heat collection fan 802 is connected to the diverter pipe 801, fix the heat collection fan to the other end of the waste heat recovery component 8 and tighten the fixing screws. After the waste heat recovery component is integrated and inspected, confirm that the battery pack box 805 and the exhaust port 804 are integrated into the corresponding positions of the waste heat recovery component 8 as designed and that there is no looseness of any component. Align the assembled waste heat recovery component 8 with the outer connecting interface of the microwave oven heating cavity assembly 11 and fix it by welding, flange connection or preset fasteners to ensure that the connection is sealed and reliable and to avoid leakage of waste heat from the heating cavity.
