Technical Field
[0001] This invention relates to the field of delivery robot technology, and more specifically to a food delivery robot with a heat preservation function. Background Technology
[0002] Delivery robots are machines that can replace humans in delivering goods. Equipped with drive wheels and steering wheels on their chassis, and guided by laser sensors, they can move freely and turn, allowing them to reach any designated location. Especially useful are food delivery robots in hotels. These intelligent devices play a vital role in the catering industry, delivering food from the kitchen to guest rooms after guests order remotely. Food delivery robots use sensors to detect their surroundings and utilize the collected data for autonomous navigation. The robot's mechanical structure must ensure stable movement, and it needs corresponding carrying devices to store various types of food to be delivered. Since it takes time for food to go from being prepared to being delivered to its destination, existing food delivery robots usually keep the delivered food warm. However, the temperature in areas far from the heating point often deviates, resulting in poor food insulation in those areas. Therefore, we propose a food delivery robot with insulation function. Summary of the Invention
[0003] To solve the above-mentioned technical problems, the present invention provides a food delivery robot with heat preservation function, comprising: A storage cylinder, wherein an electric roller is provided at the bottom of the storage cylinder; An infrared sensor, which is used to detect the surrounding environment by infrared ranging; The heat preservation device evenly distributes hot air inside the storage cylinder by jetting air, preventing temperature deviations in areas far from the heating point from resulting in poor food heat preservation in those areas. A carrying device for stably holding multiple food items that need to be delivered; The sterilization device uses ultraviolet light to thoroughly sterilize the area inside the storage cylinder, preventing bacteria from growing in the internal insulation environment after prolonged use and causing food to gradually spoil. The inner wall of the storage cylinder is provided with an arc-shaped long groove, and an electric arc gate is slidably connected to the inner wall of the arc-shaped long groove. The bottom of the storage cylinder is rotatably connected to the top of the electric roller via a rotating bolt. The inner wall of the storage cylinder is fixedly connected to the outer side of the heat preservation device. The inner wall of the storage cylinder is fixedly connected to the outer side of the carrying device. The top of the carrying device is fixedly connected to the bottom of the sterilization device. The heat preservation device includes: An arc-shaped hollow shell, wherein an arc-shaped electric heating plate is provided on the inner wall of the arc-shaped hollow shell; An arc-shaped ventilation panel, with a small water pump installed at its bottom; The inner side of the arc-shaped ventilation plate is provided with arc-shaped air holes. By opening multiple arc-shaped air holes on the inner side of the arc-shaped ventilation plate, hot air is sprayed out evenly to keep the inside of the storage cylinder warm and prevent the temperature of areas far from the heating point from being different, which would result in poor food insulation in those areas. The inner wall of the arc-shaped hollow shell is fixedly connected to the outer side of the arc-shaped heating plate, the top of the arc-shaped hollow shell is connected to the air inlet of the small air pump, and the air outlet of the small air pump is connected to the bottom of the arc-shaped ventilation plate. The outer side of the arc-shaped hollow shell is fixedly connected to the inner wall of the storage cylinder, and the outer side of the arc-shaped ventilation plate is fixedly connected to the inner wall of the storage cylinder. An annular protective plate is fitted and fixedly connected to the outer side of the storage cylinder, and the outer side of the annular protective plate is fixedly connected to one end of the infrared sensor. The inner wall of the arc-shaped hollow shell is fixedly connected to an arc-shaped inclined plate. By setting the arc-shaped inclined plate at the bottom of the arc-shaped heating plate, the gas is guided to the center of the arc-shaped heating plate for full contact. This prevents some of the gas sucked in by the small air pump from passing directly over the sides of the arc-shaped heating plate without being heated, resulting in poor heat preservation of the ejected gas. The inner side of the arc-shaped ventilation plate is fixedly connected to an arc-shaped guide plate. By setting the arc-shaped guide plate on the inner side of the arc-shaped ventilation plate, some of the hot gas is guided to both sides for dispersion. This prevents the gas flow from being affected by the gas being sucked in at the bottom of the arc-shaped hollow shell, resulting in poor diffusion of the hot gas ejected directly from the arc-shaped air holes. The outer surface of the arc-shaped guide plate has ventilation holes. By setting multiple ventilation holes on the surface of the arc-shaped guide plate, some of the hot gas on the surface of the arc-shaped guide plate is transported normally. This prevents all the hot gas ejected from the arc-shaped air holes from being guided to both sides along the arc-shaped guide plate, making it difficult to achieve a uniform dispersion effect. Two arc-shaped inclined plates are provided, and the two arc-shaped inclined plates are distributed at the bottom of the arc-shaped heating plate. Two arc-shaped guide plates are provided, and the two arc-shaped guide plates are distributed on the inner side of the arc-shaped ventilation plate.
[0004] Furthermore, the loading device includes an electric turntable, the top of which is rotatably connected to a circular rotating plate via a rotating bolt. A long truncated cone is fixedly connected to the top of the circular rotating plate, and a semi-circular block is fixedly connected to the outer side of the long truncated cone. An arc-shaped stop is fixedly connected to the top of the semi-circular block. Rotating the arc-shaped stop stops the top of the thin threading rod, preventing the second and third circular blocks within the built-in circular groove from being affected by pressure and, upon losing thrust, causing the thin threading rod to move upwards and automatically release the suction force on the food. The outer side of the truncated cone has arc-shaped perforations. Multiple arc-shaped perforations on the long truncated cone facilitate the storage of large quantities of food, preventing the storage cylinder from having a small delivery capacity and affecting delivery efficiency when there is a large amount of food to be delivered and it is difficult to stack. The inner wall of each arc-shaped perforation has an internal circular groove, and the inner wall of the internal circular groove has a circular bottom groove. A thin through-rod is slidably connected to the top of the long truncated cone. A strip-shaped locking block is fixedly connected to the outer side of the thin through-rod. Rotating the arc-shaped stop block to the bottom of the strip-shaped locking block engages the strip-shaped locking block. The bottom of the block is supported and limited to prevent the second and third round blocks from falling downwards due to gravity when the built-in round groove is not blocked, thus affecting the subsequent downward pressure effect. A side connecting rod is fixedly connected to the outside of the thin through rod. The end of the side connecting rod away from the thin through rod is fixedly connected to the first round block. An arc-shaped side rod is fixedly connected to the outside of the first round block. The end of the arc-shaped side rod away from the first round block is fixedly connected to the second round block. The top of the first round block is fixedly connected to the third round block through a connecting rod. When the second and third round blocks move downwards, they generate suction force on the inside of the built-in round groove, which is covered and blocked by food, to firmly suck the food on the top of the built-in round groove, preventing the food placed in the arc-shaped perforation from being shaken and tipping over or falling out of the arc-shaped perforation, thus affecting delivery. The outside of the electric turntable is fixedly connected to the inner wall of the storage cylinder. The top of the circular rotating plate is fixedly connected to the bottom of the sterilization device. The outside of the second round block is slidably connected to the inner wall of the built-in round groove. The outside of the third round block is slidably connected to the inner wall of the built-in round groove.
[0005] Furthermore, the sterilization device includes a vertical ultraviolet lamp. By rotating the vertical ultraviolet lamp on a circular rotating plate, the interior of the storage cylinder is thoroughly sterilized, preventing the continuous growth of bacteria in the internal insulation environment after prolonged use, which could lead to food spoilage. An arc-shaped connecting rod is fixedly connected to the top of the vertical ultraviolet lamp. A square lens is rotatably connected to the end of the arc-shaped connecting rod away from the vertical ultraviolet lamp via a rotating bolt. By rotating the square lens around the bottom of the arc-shaped connecting rod, the angle of the square lens is adjusted, refracting the ultraviolet lamp to different positions. This prevents areas within the storage cylinder blocked by the elongated truncated cone from being unable to receive and cover the ultraviolet light, thus affecting the sterilization effect. An annular sleeve is fitted and fixedly connected to the top of the vertical ultraviolet lamp. A return spring is fixedly connected to the bottom of the annular sleeve. The increasing return force as the return spring extends causes the annular slider and the long strip rod to move back above the square lens. To prevent the long bar from blocking the square lens when it is at the bottom of the arc-shaped connecting rod, making it difficult for the square lens to rotate and adjust its angle, the bottom of the retraction spring is fixedly connected to an annular slider, the bottom of the annular slider is fixedly connected to an annular sponge block, the outer side of the annular sleeve block is fixedly connected to the long bar, and the bottom of the long bar is fixedly connected to the long bar and the strip sponge block. When the strip sponge block and the annular sponge block move down, they wipe and clean the surface of the vertical ultraviolet lamp and the square lens, preventing the surface of the vertical ultraviolet lamp and the square lens from being fogged or covered with oil after long-term use, which would affect the irradiation effect. The bottom of the vertical ultraviolet lamp is fixedly connected to the top of the circular rotating plate. The annular slider is sleeved on the outside of the vertical ultraviolet lamp and slidably connected to the vertical ultraviolet lamp. The annular sponge block is sleeved on the outside of the vertical ultraviolet lamp and slidably connected to the vertical ultraviolet lamp. The outer side of the annular sponge block is fixedly connected to one side of the strip sponge block.
[0006] The beneficial effects of this invention are as follows: 1. This invention uses multiple arc-shaped air holes on the inner side of the arc-shaped ventilation plate to evenly spray hot air and keep the inside of the storage cylinder warm. This prevents temperature deviations in areas far from the heating point, which often result in poor food insulation in those areas. Multiple arc-shaped perforations on the long cylindrical platform facilitate the storage of large quantities of food. This prevents the storage cylinder from having a small delivery capacity when there is a large amount of food to be delivered and it is difficult to stack. A vertical ultraviolet lamp is installed on the circular rotating plate and rotates together to thoroughly disinfect the inside of the storage cylinder. This prevents bacteria from growing in the internal insulation environment of the storage cylinder after long-term use, which would cause the food to gradually spoil.
[0007] 2. This invention incorporates a heat preservation device. An arc-shaped inclined plate at the bottom of the arc-shaped heating plate guides the gas flow to the center of the arc-shaped heating plate for full contact, preventing some gas drawn in by the small air pump from passing directly over the sides of the arc-shaped heating plate without being heated, resulting in poor heat preservation. Multiple arc-shaped air holes on the inner side of the arc-shaped ventilation plate evenly spray hot air to insulate the inside of the storage cylinder, preventing temperature deviations in areas far from the heating point that lead to poor food heat preservation. An arc-shaped guide plate on the inner side of the arc-shaped ventilation plate guides some of the hot air to both sides for dispersion, preventing poor diffusion of hot air directly sprayed from the arc-shaped air holes due to gas being drawn in from the bottom of the arc-shaped shell affecting gas flow. Multiple ventilation holes on the surface of the arc-shaped guide plate facilitate the normal transport of some hot air from the surface, preventing all the hot air sprayed from the arc-shaped air holes from being guided to both sides along the arc-shaped guide plate, thus achieving a uniform dispersion effect.
[0008] 3. This invention, by setting up a loading device, facilitates the storage of large quantities of food by opening multiple arc-shaped perforations on a long cylindrical platform. This prevents the storage cylinder from having a small delivery capacity when there is a large amount of food to be delivered and it is difficult to stack, thus affecting delivery efficiency. The internal circular groove, which is covered and sealed by food, generates suction to firmly hold the food at the top of the internal circular groove, preventing the food placed in the arc-shaped perforations from tipping over or falling out of the arc-shaped perforations and affecting delivery. By rotating the arc-shaped stop block to stop and limit the top of the thin rod, it prevents the second and third circular blocks in the internal circular groove from being affected by pressure and causing the thin rod to move upward after losing thrust, automatically releasing the suction to the food. Rotating the arc-shaped stop block to the bottom of the strip-shaped block provides support and limit to the bottom of the strip-shaped block, preventing the second and third circular blocks from falling downward due to gravity when the internal circular groove is not sealed, thus affecting the subsequent downward pressing effect.
[0009] 4. This invention incorporates a sterilization device. A vertical ultraviolet lamp, mounted on a circular rotating plate, rotates to thoroughly disinfect the interior of the storage cylinder. This prevents bacteria from proliferating in the insulated environment after prolonged use, thus preventing food spoilage. The square lens rotates around the bottom of the arc-shaped connecting rod to adjust its angle, refracting the ultraviolet lamp to different positions. This prevents areas within the storage cylinder from being blocked by the elongated truncated cone, which would hinder ultraviolet light coverage and affect sterilization. The strip-shaped and annular sponge blocks clean the surfaces of the vertical ultraviolet lamp and square lens as they move downwards, preventing fogging or oil buildup that could affect irradiation after prolonged use. The increasing retraction force of the spring during extension moves the annular slider and strip-shaped rod back above the square lens, preventing the strip-shaped rod from obstructing the square lens's rotation and hindering angle adjustment when it's at the bottom of the arc-shaped connecting rod.

[0012] For the first embodiment, please refer to... Figures 1-4This invention relates to a food delivery robot with heat preservation function, comprising: Storage cylinder 1, with electric rollers 2 installed at the bottom of storage cylinder 1; Infrared sensor 5, which is used to detect the surrounding environment by infrared ranging; The heat preservation device 6 evenly disperses hot air into the storage cylinder 1 by jetting air. The loading device 7 is used to stably hold multiple food items that need to be delivered; Sterilization device 8, which uses ultraviolet sterilization to thoroughly sterilize the area inside the storage cylinder 1; The inner wall of the storage cylinder 1 is provided with an arc-shaped long groove 3, and an electric arc gate 4 is slidably connected to the inner wall of the arc-shaped long groove 3; The bottom of the storage cylinder 1 is rotatably connected to the top of the electric roller 2 by a rotating bolt. The inner wall of the storage cylinder 1 is fixedly connected to the outer side of the heat preservation device 6. The inner wall of the storage cylinder 1 is fixedly connected to the outer side of the carrying device 7. The top of the carrying device 7 is fixedly connected to the bottom of the sterilization device 8. The heat preservation device 6 includes: An arc-shaped hollow shell 601, with an arc-shaped electric heating plate 602 installed on the inner wall of the arc-shaped hollow shell 601; The curved ventilation panel 603 has a small water pump installed at its bottom; The inner side of the arc-shaped ventilation plate 603 is provided with arc-shaped air holes 605; The inner wall of the arc-shaped hollow shell 601 is fixedly connected to the outer side of the arc-shaped heating plate 602. The top of the arc-shaped hollow shell 601 is connected to the air inlet of the small air pump 604. The air outlet of the small air pump 604 is connected to the bottom of the arc-shaped ventilation plate 603. The outer side of the arc-shaped hollow shell 601 is fixedly connected to the inner wall of the storage cylinder 1, and the outer side of the arc-shaped ventilation plate 603 is fixedly connected to the inner wall of the storage cylinder 1. An annular protective plate 9 is fitted and fixedly connected to the outer side of the storage cylinder 1, and the outer side of the annular protective plate 9 is fixedly connected to one end of the infrared sensor 5. An arc-shaped inclined plate 606 is fixedly connected to the inner wall of the arc-shaped shell 601, and an arc-shaped guide plate 607 is fixedly connected to the inner side of the arc-shaped ventilation plate 603. A ventilation hole 608 is opened on the outer surface of the arc-shaped guide plate 607. Two curved inclined plates 606 are provided, and the two curved inclined plates 606 are distributed at the bottom of the curved electric heating plate 602. Two curved guide plates 607 are provided, and the two curved guide plates 607 are distributed inside the curved ventilation plate 603. In use, the electric curved door 4 is opened and the food to be delivered is placed in the loading device 7. The electric curved door 4 is closed and the air inside the storage cylinder 1 is heated by the heat preservation device 6 and then evenly sprayed out to keep the food in each position warm. At the same time, the sterilization device 8 sterilizes the inside of the storage cylinder 1. The area is disinfected with ultraviolet light. Based on the surrounding environment detected by infrared sensor 5, the robot plans its path and drives the electric rollers 2 to move the storage cylinder 1 towards its destination. An annular protective plate 9 is fitted onto the outside of the storage cylinder 1 near the bottom to increase the robot's stability during movement and prevent it from tipping over due to collisions. A small air pump 604 evacuates the arc-shaped shell 601. After entering the arc-shaped shell 601, the gas flows along the inclined surface of the arc-shaped inclined plate 606 to the center of the arc-shaped heating plate 602. Heating is achieved by guiding gas to the center of the arc-shaped heating plate 602 through an arc-shaped inclined plate 606 at the bottom of the arc-shaped heating plate 602 for full contact. The gas then flows from the center of the arc-shaped heating plate 602 outwards to the sides, where it is drawn into the arc-shaped ventilation plate 603 by a small air pump 604. When the heated gas fills the arc-shaped ventilation plate 603, it is evenly sprayed outwards through the inner arc-shaped air holes 605. Multiple arc-shaped air holes 605 on the inner side of the arc-shaped ventilation plate 603 ensure the even spraying of hot gas for storage. The inside of cylinder 1 is insulated. Gas ejected from the arc-shaped air hole 605 comes into contact with the arc-shaped guide plate 607. Part of the hot gas flows to both sides along the arc surface of the arc-shaped guide plate 607, while the other part of the hot gas flows forward directly through the ventilation hole 608. By setting the arc-shaped guide plate 607 inside the arc-shaped ventilation plate 603, part of the hot gas is guided to both sides for dispersion. By opening multiple ventilation holes 608 on the surface of the arc-shaped guide plate 607, it is easy to transport part of the hot gas on the surface of the arc-shaped guide plate 607 normally.
[0013] For the second embodiment, please refer to... Figures 1-8This invention provides a food delivery robot with heat preservation function: the carrying device 7 includes an electric turntable 701, the top of which is rotatably connected to a circular turntable 702 via a rotating bolt; the top of the circular turntable 702 is fixedly connected to a long truncated cone 703; a semi-circular block 704 is fixedly connected to the outer side of the long truncated cone 703; an arc-shaped stop block 705 is fixedly connected to the top of the semi-circular block 704; an arc-shaped through hole 706 is formed on the outer side of the long truncated cone 703; an inner circular groove 707 is formed on the inner wall of the arc-shaped through hole 706; a circular bottom groove 708 is formed on the inner wall of the inner circular groove 707; a thin through rod 709 is slidably connected through and to the top of the long truncated cone 703; and a strip-shaped locking block 7 is fixedly connected to the outer side of the thin through rod 709. 10. A side connecting rod 711 is fixedly connected to the outer side of the thin through rod 709. A first circular block 712 is fixedly connected to the end of the side connecting rod 711 away from the thin through rod 709. An arc-shaped side rod 713 is fixedly connected to the outer side of the first circular block 712. A second circular block 714 is fixedly connected to the end of the arc-shaped side rod 713 away from the first circular block 712. A third circular block 715 is fixedly connected to the top of the first circular block 712 via a connecting rod. The outer side of the electric turntable 701 is fixedly connected to the inner wall of the storage cylinder 1. The top of the circular rotating plate 702 is fixedly connected to the bottom of the sterilization device 8. The outer side of the second circular block 714 is slidably connected to the inner wall of the built-in circular groove 707. The outer side of the third circular block 715 is slidably connected to the inner wall of the built-in circular groove 707. The sterilization device 8 includes a vertical ultraviolet lamp 801. An arc-shaped connecting rod 802 is fixedly connected to the top of the vertical ultraviolet lamp 801. A square lens 803 is rotatably connected to the end of the arc-shaped connecting rod 802 away from the vertical ultraviolet lamp 801 via a rotating bolt. An annular sleeve block 804 is fitted and fixedly connected to the top of the vertical ultraviolet lamp 801. A retraction spring 805 is fixedly connected to the bottom of the annular sleeve block 804. An annular slider 806 is fixedly connected to the bottom of the retraction spring 805. An annular sponge block 807 is fixedly connected to the bottom of the annular slider 806. A strip-shaped long rod 808 is fixedly connected to the outside of the annular sleeve block 804. A strip-shaped sponge block 809 is fixedly connected to the bottom of the strip-shaped long rod 808. The bottom of the vertical ultraviolet lamp 801 is connected to a circular rotating plate 70. The top of the device 2 is fixedly connected. An annular slider 806 is fitted onto the outside of the vertical UV lamp 801 and slidably connected to it. An annular sponge block 807 is fitted onto the outside of the vertical UV lamp 801 and slidably connected to it. The outer side of the annular sponge block 807 is fixedly connected to one side of the strip sponge block 809. In use, the food to be delivered is placed sequentially into the arc-shaped perforations 706 of the elongated circular platform 703. Simultaneously, the electric turntable 701 drives the circular rotating plate 702 to rotate. The rotation of the circular rotating plate 702 causes the top sterilization device 8 and multiple elongated circular platforms 703 to rotate together. As the multiple elongated circular platforms 703 rotate with the circular rotating plate 702, food can be placed inside or from different elongated circular platforms 703. The food is removed from the container. Multiple curved perforations 706 on the elongated truncated cone 703 facilitate the storage of large quantities of food. After the food is placed, pressing down on the thin threading rod 709 moves the first circular block 712 downwards via the side connecting rod 711. As the first circular block 712 moves downwards, the outer curved side rod 713 and the top connecting rod together move the second circular block 714 and the third circular block 715 downwards within the built-in circular groove 707. The downward movement of the second and third circular blocks 714 and 715 creates suction on the top of the built-in circular groove 707, which is currently blocked by food, tightly holding the food in place. The thin threading rod 709 maintains the second and third circular blocks 714 and 715 within the built-in circular groove 707 throughout its downward movement. After the rod 709 has moved down, the arc-shaped stop 705 on the semicircular block 704 is turned towards the thin rod 709 to block the top of the thin rod 709. By rotating the arc-shaped stop 705, the top of the thin rod 709 is blocked and limited. When it is necessary to remove the food from the arc-shaped hole, the arc-shaped stop 705 is rotated to release the blocking and limiting effect on the thin rod 709. At this time, the second circular block 714 and the third circular block 715 in the built-in circular groove 707 are affected by the pressure and drive the thin rod 709 to move upward to release the suction force on the food. When the strip-shaped locking block 710 on the outside of the thin rod 709 moves above the arc-shaped stop 705, the second circular block 714 and the third circular block 715 move exactly to a position where the top surface is flush with the bottom surface of the inner wall of the arc-shaped hole.The arc-shaped stop 705 is rotated to the bottom of the strip-shaped latch 710 to support and limit its position. A vertical ultraviolet lamp 801 is mounted on the circular rotating plate 702 and rotates together to thoroughly disinfect the inside of the storage cylinder 1. The angle of the square lens 803 is adjusted by rotating it around the bottom of the arc-shaped connecting rod 802, refracting the ultraviolet lamp to different positions. After prolonged use, the square lens 803 and the ultraviolet lamp are rotated back between the two strip-shaped rods 808. Pulling down the strip-shaped rods 808 causes the annular slider 806 to move downwards. As the annular slider 806 moves downwards, it activates the return spring at the top. When 805 extends, the annular slider 806 and the strip rod 808 move downwards, respectively driving the annular sponge block 807 and the strip sponge block 809 at the bottom to move together. As the strip sponge block 809 and the annular sponge block 807 move downwards, they clean the surfaces of the vertical ultraviolet lamp 801 and the square lens 803. After cleaning, the pull on the strip rod 808 is released. At this time, the return spring 805 loses its downward pulling force and, through the return force, drives the annular slider 806 and the strip rod 808 to move upwards. The increasing return force during the extension of the return spring 805 drives the annular slider 806 and the strip rod 808 back to above the square lens 803.
[0014] In operation, the electric arc gate 4 is opened to place the food to be delivered into the carrying device 7. The electric arc gate 4 is closed, and the air inside the storage cylinder 1 is heated by the heat preservation device 6 and then evenly sprayed out to keep the food warm in all positions. Simultaneously, the sterilization device 8 uses ultraviolet light to disinfect bacteria inside the storage cylinder 1. The robot plans its movement path based on the surrounding environment detected by the infrared sensor 5, driving the electric rollers 2 to move the storage cylinder 1 towards its destination. An annular protective plate 9 is fitted onto the outside of the storage cylinder 1 near the bottom to increase the robot's stability during movement and prevent it from tipping over due to collisions. A small air pump 604 evacuates air from the arc-shaped shell 601, and the gas enters the arc-shaped shell 601 and travels along the arc... The gas flows along the inclined surface of the inclined plate 606 to the center of the arc-shaped heating plate 602 and is heated. The gas is guided to the center of the arc-shaped heating plate 602 by the inclined plate 606 at the bottom of the arc-shaped heating plate 602 for full contact. Then, the gas flows from the center of the arc-shaped heating plate 602 to both sides and is drawn into the arc-shaped ventilation plate 603 by the small air pump 604. When the heated gas fills the arc-shaped ventilation plate 603, it is evenly sprayed outwards through the inner arc-shaped air holes 605. Multiple arc-shaped air holes 605 on the inner side of the arc-shaped ventilation plate 603 evenly spray the hot gas to insulate the interior of the storage cylinder 1. The gas sprayed from the arc-shaped air holes 605 contacts the arc-shaped guide plate 607, and some of the hot gas flows along the arc-shaped guide plate 607. The airflow is dispersed to both sides by the arc surface of the 7, while another part of the hot air flows forward directly through the ventilation holes 608. An arc-shaped guide plate 607 is installed inside the arc-shaped ventilation plate 603 to guide some of the hot air to both sides for dispersion. Multiple ventilation holes 608 are opened on the surface of the arc-shaped guide plate 607 to facilitate the normal transport of some of the hot air. The food to be delivered is placed sequentially in the arc-shaped perforations 706 of the elongated cylindrical platform 703 for storage. Simultaneously, the electric turntable 701 drives the circular rotating plate 702 to rotate. The rotation of the circular rotating plate 702 drives the sterilization device 8 at the top and the multiple elongated cylindrical platforms 703 to rotate together. As the multiple elongated cylindrical platforms 703 rotate with the circular rotating plate 702, the food can be placed on different elongated cylindrical platforms 703. 3. Food can be stored in or removed from the container. Multiple arc-shaped perforations 706 are made on the elongated truncated cone 703 to facilitate the storage of large quantities of food. After the food is placed, pressing down on the thin perforation rod 709 moves the first circular block 712 downward via the side connecting rod 711. When the first circular block 712 moves downward, the second circular block 714 and the third circular block 715 move downward together in the built-in circular groove 707 through the outer arc-shaped side rod 713 and the top connecting rod. When the second circular block 714 and the third circular block 715 move downward, they generate suction force on the inside of the built-in circular groove 707, which is covered and blocked by food, to firmly hold the food on the top of the built-in circular groove 707. When the thin perforation rod 709 moves downward, it always keeps the second circular block 714 and the third circular block 715 in the built-in circular groove 707.After the thin threading rod 709 has moved down, the arc-shaped stop 705 on the semicircular block 704 is turned towards the thin threading rod 709 to block its top. By rotating the arc-shaped stop 705, the top of the thin threading rod 709 is blocked and limited. When it is necessary to remove the food from the arc-shaped hole, rotating the arc-shaped stop 705 releases the blocking and limiting effect on the thin threading rod 709. At this time, the second circular block 714 and the third circular block 715 in the built-in circular groove 707 are affected by pressure and drive the thin threading rod 709 to move upward back. The suction force on the food is released. When the strip-shaped locking block 710 on the outside of the thin perforation rod 709 moves above the arc-shaped stop block 705, the second round block 714 and the third round block 715 move to a position where their top surfaces are flush with the bottom surface of the inner wall of the arc-shaped perforation. The arc-shaped stop block 705 is rotated to the bottom of the strip-shaped locking block 710 to support and limit its position. The vertical ultraviolet lamp 801, mounted on the circular rotating plate 702, rotates together to thoroughly disinfect the inside of the storage cylinder 1. The square lens 803 is then used to disinfect the inside of the storage cylinder 1. Rotating around the bottom of the arc-shaped connecting rod 802 adjusts the angle of the square lens 803, refracting the ultraviolet lamp to different positions. After prolonged use, the square lens 803 is rotated back between the two strip rods 808. Pulling down the strip rods 808 causes the annular slider 806 to move downwards. As the annular slider 806 moves downwards, it extends the top retraction spring 805. The downward movement of the annular slider 806 and the strip rod 808 respectively activates the bottom annular sponge block 807 and the strip rod 808. The sponge block 809 moves together with the other two. As the strip-shaped sponge block 809 and the ring-shaped sponge block 807 move downwards, they clean the surfaces of the vertical ultraviolet lamp 801 and the square lens 803. After cleaning, the pull on the strip-shaped rod 808 is released. At this time, the return spring 805 loses its downward pulling force and, through the return force, drives the ring-shaped slider 806 and the strip-shaped rod 808 to move upwards. The increasing return force as the return spring 805 extends further drives the ring-shaped slider 806 and the strip-shaped rod 808 back above the square lens 803.
