Description

Technical Field

[0001] This application relates to the field of household appliance technology, specifically to an automatic food feeder with heat preservation function. Background Technology

[0002] In real life, many elderly people are unable to feed themselves due to limited dexterity, requiring assistance from others. This reduces their autonomy in eating, sometimes preventing them from choosing mealtimes according to their own appetite, and sometimes forcing them to eat faster to accommodate the feeder's schedule. Sometimes, children are too busy with work to feed their elderly parents, causing inconvenience for both the children and the elderly, and potentially leading to stomach problems due to irregular mealtimes. Therefore, a feeding machine has emerged that automatically picks up food and delivers it to the user's mouth, achieving automated feeding and significantly improving the well-being of the elderly.

[0003] However, when the weather is cold, or when elderly people with limited mobility or Parkinson's disease use this type of feeding machine, the machine needs a longer time to recognize and control the food spoon to accurately put into the elderly person's mouth. When the elderly person's mouth is constantly shaking, it will cause the recognition and food delivery time to be too long, which will cause the food in the spoon to get cold and reduce the user experience. Summary of the Invention

[0004] The purpose of this application is to provide an automatic food warming feeder to solve the problem that the food in the spoon gets cold when the feeder is aimed at the user's mouth for a long time.

[0005] To achieve the above objectives, this application provides an automatic heat-preserving feeding machine, comprising a base with a food tray on one side, at least one food container for holding food on one side of the food tray, the opening of the food container facing upwards; a movable robotic arm connected to the base and located on the other side of the food tray, the movable robotic arm comprising a first robotic arm and a second robotic arm, the first robotic arm being rotatably connected to the base with its rotation axis arranged vertically, and the second robotic arm being rotatably connected to the end of the first robotic arm away from the base with its rotation axis arranged horizontally; and a feeding assembly including a control base. The system includes a base and a spoon. The control base is connected to the end of the second robotic arm away from the first robotic arm, and the spoon is connected to the side of the control base away from the second robotic arm. The control base is used to sense the food container and the position of the user's mouth. The controller is used to control the spoon to take food out of the food container and to put the food into the user's mouth. The base has a hot air device inside, and the spoon has an air guide chamber that communicates with the hot air device. The air guide chamber is also connected to the air vent on the surface of the spoon. The controller controls the hot air device to generate hot air and send it to the spoon to heat the food.

[0006] Thus, by providing a tray on the base, with at least one food container on one side of the tray, the opening of the food container facing upwards, the food is easily accessible. A movable robotic arm is connected to the base and located on the other side of the tray. The movable robotic arm includes a first robotic arm and a second robotic arm. The first robotic arm is rotatably connected to the base with its rotation axis arranged vertically. The second robotic arm is rotatably connected to the end of the first robotic arm away from the base with its rotation axis arranged horizontally. The first and second robotic arms, with their rotation axes in different directions, can retrieve food from multiple directions, making it convenient and quick to use. A feeding component includes a control base and a food spoon. The control base is connected to the end of the second robotic arm away from the first robotic arm, and the food spoon is connected to the control base away from the second robotic arm. On one side of the arm, a control base is used to sense the position of the food container and the user's mouth. A controller is set up to control the feeding spoon to take food out of the food container and to deliver the food to the user's mouth. The controller automatically controls the feeding spoon to sense the position of the food container and the user's mouth and deliver the food to the user's mouth, realizing the automation of the feeding machine. A hot air device is installed inside the base, and the feeding spoon has an air guide chamber that is connected to the hot air device. The air guide chamber is also connected to the air guide port on the surface of the feeding spoon. The controller controls the hot air device to generate hot air and deliver it to the feeding spoon to heat the food. This ensures that the feeding spoon is heated by the hot air generated by the hot air device when automatically taking food, preventing the food from getting cold during the process of feeding the user's mouth, which could lead to poor taste or gastrointestinal discomfort, thus improving the user experience.

[0007] In a preferred embodiment of an automatic heat-preserving feeding machine, a recognition sensor is provided on the side of the control base facing the food spoon. The recognition sensor is electrically connected to the hot air device and the controller, so that when the recognition sensor detects that the food spoon has entered the user's mouth, the controller controls the hot air device to stop outputting hot air.

[0008] Thus, by installing a recognition sensor on the side of the control base facing the rice spoon, and electrically connecting the recognition sensor to the hot air device and the controller respectively, when the recognition sensor detects that the rice spoon has entered the user's mouth, the controller controls the hot air device to stop outputting hot air. When the rice spoon is outside the user's mouth, the controller controls the hot air device to output hot air to heat the food and keep the food inside the rice spoon warm. When the rice spoon enters the user's mouth, the hot air output stops to prevent the hot air from burning the user's mouth or causing external airflow to enter the stomach through the user's mouth, causing discomfort such as bloating, thus further improving the user experience.

[0009] In a preferred embodiment of an automatic heat-preserving feeding machine, the feeding spoon includes a support plate removably covering the air duct cavity, the support plate being used to shield the air duct cavity to prevent food residue from entering, an air vent being disposed on the support plate to communicate with the air duct cavity, and the air vent having staggered grilles to prevent food from entering the air vent.

[0010] Thus, by setting the feeding spoon including a detachable support plate covering the air guide cavity, the support plate is used to block the air guide cavity to prevent food residue from entering. By installing the support plate to block the air guide cavity, it is possible to prevent food residue or oil droplets from entering the air guide cavity during use, which would cause hot air blockage and prevent output. When the feeding machine is not in use, the support plate can be removed to expose the air guide cavity for easy cleaning by the user. In addition, the air guide is set on the support plate to communicate with the air guide cavity. The air guide has staggered grilles to prevent food from entering the air guide and prevent food residue from entering the air guide cavity along the air guide and causing hot air blockage and preventing output.

[0011] In a preferred embodiment of an automatic heat-preserving feeding machine, the food spoon is provided with a food-receiving slot arranged upwards. The food-receiving slot includes a first end near the user's mouth and a second end near the control base. An air vent is located at the first end and is arranged towards the second end to form a hot air channel between the first end and the second end to heat the food.

[0012] Thus, by providing a food-holding slot in the rice spoon, with the slot facing upwards, the slot includes a first end near the user's mouth and a second end near the control base. An air vent is located at the first end and faces the second end, forming a hot air channel between the first and second ends to heat the food. This causes the hot air blown out of the air vent to move away from the user's mouth, preventing burns to the user's mouth when heating the food, and also preventing excessive hot air from entering the stomach along the user's mouth, causing bloating and other discomfort, thus further improving the user experience.

[0013] In a preferred embodiment of an automatic heat-preserving feeding machine, a suction port for drawing in hot air is provided at the second end. The suction port is located at a lower position at the second end, and a guide port is located at a lower position at the first end, so as to form an arc-shaped hot air flow channel from the guide port to the suction port inside the receiving groove.

[0014] Thus, by setting an air inlet for drawing in hot air at the second end, with the air inlet located at a lower position at the second end and the air guide located at a lower position at the first end, an arc-shaped hot air flow channel is formed inside the receiving groove, allowing the hot air to flow from the air guide to the air inlet. This enables the hot air to form an arc-shaped hot air flow channel inside the rice spoon when heating the food inside the rice spoon, fully heating the food inside the rice spoon, improving the thermal efficiency of the hot air device, and quickly heating and keeping the food warm.

[0015] In a preferred embodiment of an automatic heat-preserving feeding machine, there are multiple air vents clustered at the first end, and air intakes are distributed in an arc-shaped interval along the circumference of the second end; or, there are multiple air vents clustered at the first end, and multiple air intakes are clustered at the second end; or, there are multiple air vents clustered at the first end, and multiple air intakes are clustered at the second end; or, there are multiple air vents clustered at the first end, and multiple air intakes are clustered at the second end; or, there are multiple air vents clustered at the first end, and multiple air intakes are distributed in an arc-shaped interval along the circumference of the second end.

[0016] Thus, by setting multiple air vents clustered at the first end and air intakes arranged in an arc-shaped interval along the circumference of the second end, a hot air flow channel from convergence to diffusion is formed inside the rice spoon, fully expanding the heating area of ​​the hot air; or, by setting multiple air vents clustered in an arc-shaped interval along the circumference of the first end and multiple air intakes clustered at the second end, a hot air flow channel from diffusion to convergence is formed inside the rice spoon, ensuring the heating effect of the larger area of ​​the second end; or, by setting multiple air vents clustered at the first end and multiple air intakes clustered at the second end, a concentrated bundle of hot air flow channel is formed inside the rice spoon, improving the heating effect; or, by setting multiple air vents clustered in an arc-shaped interval along the circumference of the first end and multiple air intakes clustered in an arc-shaped interval along the circumference of the second end, a hot air flow channel with a larger diffusion surface is formed inside the rice spoon, improving the heat preservation effect.

[0017] In a preferred embodiment of an automatic heat-preserving feeding machine, the base is further provided with a water tray and a water-proof cover inside the water tray. The water-proof cover and the water tray enclose a steam chamber, which is connected to an air vent. A first heating element is provided below the steam chamber. The first heating element is electrically connected to the controller. The first heating element is used to heat the water in the steam chamber to generate steam and guide it into the rice spoon along the air vent.

[0018] Thus, by providing a water-holding tray on the base and a water-proof cover inside the water-holding tray, the water-proof cover and the water-holding tray enclose a steam chamber, which is connected to the air vent. Below the steam chamber is a first heating element, which is electrically connected to the controller. The first heating element is used to heat the water in the steam chamber to generate steam, which is then introduced into the rice spoon through the air vent. The steam in the steam chamber is used to heat and keep the food in the rice spoon warm and replenish water, preventing the food from drying out and losing its taste when heated by hot air. At the same time, it can soften the food, thus improving the user experience for the elderly. Meanwhile, the water-proof cover isolates part of the water for heating, quickly generating steam and preventing users from having to wait a long time to use the steam to heat and keep the food warm.

[0019] In a preferred embodiment of an automatic heat-preserving feeding machine, the bottom of the water shield is provided with a guide hole to allow the steam chamber to communicate with the outside of the water shield; or, the bottom of the water tray is provided with a drainage groove, and the bottom of the water shield is embedded in the drainage groove.

[0020] Thus, by providing a guide hole at the bottom of the water-proof cover to connect the steam chamber with the outside of the water-proof cover, or by providing a drainage groove at the bottom of the water-holding tray and embedding the bottom of the water-proof cover in the drainage groove, water from outside the steam chamber can continuously enter the steam chamber along the guide hole or drainage groove during the process of generating steam inside the steam chamber, replenishing the steam chamber with water and preventing the steam chamber from dry burning and causing safety hazards.

[0021] In a preferred embodiment of an automatic heat-preserving feeding machine, the first and second robotic arms are provided with air guiding channels, the two ends of which are respectively connected to a hot air device and an air guiding chamber. The air guiding channels are made of flexible hoses to move with the first and second robotic arms.

[0022] Thus, by providing air guide channels inside the first and second robotic arms, with both ends of the air guide channels connected to the hot air device and the air guide cavity respectively, the air guide channels are made of flexible hoses so that they move with the first and second robotic arms. This allows hot air to flow into the air guide cavity along the air guide channels inside the first and second robotic arms without affecting the flexible movement of the first and second robotic arms, thus ensuring the user experience.

[0023] In a preferred embodiment of an automatic heat-preserving feeding machine, a second heating element is provided at the bottom of the food holding tank. The second heating element is electrically connected to the controller to heat the food in the food holding tank. There are multiple food spoons, each of which is detachably connected to the control base.

[0024] Thus, by providing a second heating element at the bottom of the food container, which is electrically connected to the controller, the food in the food container is heated. There are multiple rice spoons, each detachably connected to the control base. The second heating element is used to preheat the food in the food container, preventing the food from cooling down and improving the user experience. Attached Figure Description

[0042] like Figures 1 to 8 As shown, this application provides an automatic food warming feeding machine, including a base 100, a plate 110 on the base 100, at least one food holding slot 111 for holding food on one side of the plate 110, the opening of the food holding slot 111 facing upwards; a movable robotic arm 200, connected to the base 100 and located on the other side of the plate 110, the movable robotic arm 200 includes a first robotic arm 210 and a second robotic arm 220, the first robotic arm 210 is rotatably connected to the base 100 and the rotation axis is arranged vertically, the second robotic arm 220 is rotatably connected to the end of the first robotic arm 210 away from the base 100 and the rotation axis is arranged horizontally; and a feeding component 300, including a control base 310 and a food spoon. 320, the control base 310 is connected to the end of the second robotic arm 220 away from the first robotic arm 210, and the spoon 320 is connected to the side of the control base 310 away from the second robotic arm 220. The control base 310 is used to sense the food holding slot 111 and the position of the user's mouth. The controller is used to control the spoon 320 to take food out of the food holding slot 111 and to control the spoon 320 to put the taken food into the user's mouth. The base 100 is equipped with a hot air device (not shown in the figure), and the spoon 320 is equipped with an air guide cavity 321 that communicates with the hot air device. The air guide cavity 321 is also connected to the air guide port 322 on the surface of the spoon 320. The controller controls the hot air device to generate hot air and send it to the spoon 320 to heat the food.

[0043] Understandably, when using the feeding machine, the user sits on one side of the food container 111. The first robotic arm 210 and the second robotic arm 220 control the movement of the food spoon 320 in the vertical and horizontal directions, respectively, so that the food spoon 320 moves toward the user's mouth. During the movement, the hot air device generates hot air, which flows along the air guide cavity 321 to the air guide port 322 and is blown onto the surface of the food spoon 320 to heat and keep the food in the food spoon 320 warm. Finally, the first robotic arm 210 and the second robotic arm 220 drive the food spoon 320 to deliver the warmed food into the user's mouth.

[0044] It is understood that hot air devices are a relatively mature technology in the prior art. The embodiments of this application will not be described in detail. A hot air device can be a combination of heating wire and fan, or a hot air device can be a combination of PCB heating plate and fan.

[0045] Preferably, the temperature of the hot air is set to 40-60 degrees Celsius to ensure that the food is kept warm while avoiding burns to the user's mouth.

[0046] Thus, by providing a plate 110 on the base 100, with at least one food container 111 on one side of the plate 110, the opening of the food container 111 faces upwards, making it easy to retrieve food; a movable robotic arm 200 is connected to the base 100 and located on the other side of the plate 110. The movable robotic arm 200 includes a first robotic arm 210 and a second robotic arm 220. The first robotic arm 210 is rotatably connected to the base 100 with its rotation axis arranged vertically, and the second robotic arm 220 is rotatably connected to the end of the first robotic arm 210 away from the base 100 with its rotation axis arranged horizontally. This allows for retrieval of food from multiple directions using the first robotic arm 210 and the second robotic arm 220 with their rotation axes in different directions, making it convenient and quick to use; a feeding component 300 includes a control base 310 and a food spoon 320. The control base 310 is connected to the end of the second robotic arm 220 away from the first robotic arm 210, and the food spoon 320 is connected to... A control base 310 is attached to the side opposite to the second robotic arm 220. The control base 310 is used to sense the position of the food container 111 and the user's mouth. A controller is set up to control the feeding spoon 320 to take food out of the food container 111 and to feed the food into the user's mouth. The controller automatically controls the feeding spoon 320 to sense the position of the food container 111 and the user's mouth and to feed the food into the user's mouth, realizing the automation of the feeding machine. Inside the base 100, there is a... The food spoon 320 is equipped with a hot air device. The inside of the food spoon 320 is provided with an air guide chamber 321 that communicates with the hot air device. The air guide chamber 321 is also connected to the air guide port 322 on the surface of the food spoon 320. The controller controls the hot air device to generate hot air and send it into the food spoon 320 to heat the food. This allows the food spoon 320 to be heated by the hot air generated by the hot air device when it automatically picks up food. This prevents the food from getting cold during the process of the food spoon 320 being put into the user's mouth, which could lead to poor taste or gastrointestinal discomfort for the user and improve the user experience.

[0047] like Figure 1 As shown, in a preferred embodiment of an automatic heat-preserving feeding machine, a recognition sensor 311 is provided on the side of the control base 310 facing the food spoon 320. The recognition sensor 311 is electrically connected to the hot air device and the controller, so that when the recognition sensor 311 recognizes that the food spoon 320 has entered the user's mouth, the controller controls the hot air device to stop outputting hot air.

[0048] Understandably, the identification sensor 311 can be an infrared sensor, an ultrasonic sensor, or a capacitive sensor. When it detects that the spoon 320 has entered the user's mouth, it controls the hot air device to stop outputting hot air.

[0049] Thus, by providing an identification sensor 311 on the side of the control base 310 facing the spoon 320, and electrically connecting the identification sensor 311 to the hot air device and the controller respectively, when the identification sensor 311 detects that the spoon 320 has entered the user's mouth, the controller controls the hot air device to stop outputting hot air. When the spoon 320 is outside the user's mouth, the controller controls the hot air device to output hot air to heat the food and keep the food inside the spoon 320 warm. When the spoon 320 enters the user's mouth, the hot air output stops to prevent the hot air from burning the user's mouth or causing external airflow to enter the stomach through the user's mouth, causing bloating and other discomfort, thus further improving the user experience.

[0050] like Figure 5 As shown, in a preferred embodiment of an automatic heat-preserving feeding machine, the food spoon 320 includes a support plate 323 detachably covering the air guide cavity 321. The support plate 323 is used to block the air guide cavity 321 to prevent food residue from entering. The air guide 322 is provided on the support plate 323 to communicate with the air guide cavity 321. The air guide 322 is provided with staggered grilles 324 to prevent food from entering the air guide 322.

[0051] It is understandable that the support plate 323 is snapped onto the edge of the spoon 320, or the support plate 323 is magnetically connected to the edge of the spoon 320, so as to achieve quick disassembly of the support plate 323.

[0052] Thus, by setting the feeding spoon 320 to include a support plate 323 detachably covering the air guide cavity 321, the support plate 323 is used to block the air guide cavity 321 to prevent food residue from entering. By installing the support plate 323 to block the air guide cavity 321, food residue or oil droplets can be prevented from entering the air guide cavity 321 during use, causing hot air blockage and preventing output. When the feeding machine is not in use, the support plate 323 can be removed to expose the air guide cavity for easy cleaning by the user. In addition, the air guide port 322 is set on the support plate 323 to communicate with the air guide cavity 321. The air guide port 322 is provided with staggered grilles 324 to prevent food from entering the air guide port 322 and to prevent food residue from entering the air guide cavity 321 along the air guide port 322, causing hot air blockage and preventing output.

[0053] like Figure 6As shown, in a preferred embodiment of an automatic heat-preserving feeding machine, the food spoon 320 is provided with a food receiving slot 325, which is arranged upwards. The food receiving slot 325 includes a first end 326 near the user's mouth and a second end 327 near the control base 310. An air vent 322 is located at the first end 326 and is arranged towards the second end 327 to form a hot air channel between the first end 326 and the second end 327 to heat the food.

[0054] It is understandable that the first end 326 is the pointed end of the spoon 320 facing the user's mouth, and the second end 327 is the rounded end of the spoon 320 away from the user's mouth. The area of ​​the second end 327 is larger than that of the first end 326.

[0055] Preferably, the air vent 322 is set at an angle of 20 to 45 degrees to deliver air upwards, so that all parts inside the rice spoon 320 can be heated evenly.

[0056] Thus, by providing a food-accommodating slot 325 on the rice spoon 320, the slot 325 is arranged upwards and includes a first end 326 near the user's mouth and a second end 327 near the control base 310. The air vent 322 is located at the first end 326 and is positioned towards the second end 327 to form a hot air channel between the first end 326 and the second end 327 to heat the food. This causes the hot air blown out of the air vent 322 to move away from the user's mouth, preventing the hot air from burning the user's mouth when heating the food, and also preventing too much hot air from entering the stomach along the user's mouth, causing bloating and other discomfort, thus further improving the user experience.

[0057] like Figure 7 As shown, in a preferred embodiment of an automatic heat-preserving feeding machine, the second end 327 is provided with an air inlet 328 for drawing in hot air. The air inlet 328 is located at a lower position of the second end 327, and the air guide 322 is located at a lower position of the first end 326, so as to form an arc-shaped hot air flow channel from the air guide 322 to the air inlet 328 inside the receiving groove 325.

[0058] Thus, by providing an air intake 328 for drawing in hot air at the second end 327, with the air intake 328 located at a lower position on the second end 327 and the air guide 322 located at a lower position on the first end 326, an arc-shaped hot air flow channel is formed inside the receiving groove 325, flowing from the air guide 322 to the air intake 328. This allows the hot air to form an arc-shaped hot air flow channel inside the rice spoon 320 when heating the food inside the rice spoon 320, thus fully heating the food inside the rice spoon 320, improving the thermal efficiency of the hot air device, and quickly heating and keeping the food warm.

[0059] like Figure 8As shown, in a preferred embodiment of an automatic heat-preserving feeding machine, there are multiple air vents 322 that are clustered at the first end 326, and air intakes 328 are distributed in an arc-shaped interval along the circumference of the second end 327; or, there are multiple air vents 322 that are clustered at the first end 326, and multiple air intakes 328 that are clustered at the second end 327; or, there are multiple air vents 322 that are clustered at the first end 326, and multiple air intakes 328 that are clustered at the second end 327; or, there are multiple air vents 322 that are clustered at the first end 326, and multiple air intakes 328 that are clustered at the second end 327; or, there are multiple air vents 322 that are clustered at the first end 326, and multiple air intakes 328 that are clustered at the second end 327.

[0060] Thus, by setting multiple air guide vents 322 clustered at the first end 326 and multiple air intake vents 328 arranged in an arc-shaped interval along the circumference of the second end 327, a hot air flow channel from concentration to diffusion is formed inside the rice spoon 320, fully expanding the heating area of ​​the hot air; or, by setting multiple air guide vents 322 clustered in an arc-shaped interval along the circumference of the first end 326 and multiple air intake vents 328 clustered at the second end 327, a hot air flow channel from diffusion to concentration is formed inside the rice spoon 320, ensuring that the heating area of ​​the larger first end 326 is fully expanded. The heating effect of the two ends 327; or, multiple air guides 322 are clustered at the first end 326, and multiple air intakes 328 are clustered at the second end 327, so that a clustered hot air flow channel is formed inside the rice spoon 320 to improve the heating effect; or, multiple air guides 322 are distributed in an arc-shaped interval along the circumference of the first end 326, and multiple air intakes 328 are distributed in an arc-shaped interval along the circumference of the second end 327, so that a hot air flow channel with a large diffusion surface is formed inside the rice spoon 320 to improve the heat preservation effect.

[0061] like Figure 9 As shown, in a preferred embodiment of an automatic heat-preserving feeding machine, the base 100 is further provided with a water tray 400 and a water-proof cover 410 covering the inside of the water tray 400. The water-proof cover 410 and the water tray 400 enclose a steam chamber 420. The steam chamber 420 is connected to the air vent 322. A first heating element 430 is provided below the steam chamber 420. The first heating element 430 is electrically connected to the controller. The first heating element 430 is used to heat the water in the steam chamber 420 to generate steam and guide it into the rice spoon 320 along the air vent 322.

[0062] Thus, by providing a water tray 400 and a water-proof cover 410 inside the water tray 400 on the base 100, the water-proof cover 410 and the water tray 400 enclose a steam chamber 420, which is connected to the air vent 322. A first heating element 430 is provided below the steam chamber 420 and is electrically connected to the controller. The first heating element 430 is used to heat the water in the steam chamber 420 to generate steam, which is then introduced into the rice spoon 320 through the air vent 322. The steam in the steam chamber 420 is used to heat and keep the food in the rice spoon 320 warm and replenish water, preventing the food from drying out and losing its taste when heated by hot air. At the same time, it can soften the food and improve the user experience for the elderly. Meanwhile, the water-proof cover 410 isolates part of the water for heating, quickly generating steam and preventing users from having to wait a long time to use steam to heat and keep food warm.

[0063] In a preferred embodiment of an automatic heat-preserving feeding machine, the bottom of the water shield 410 is provided with a guide hole so that the steam chamber 420 is connected to the outside of the water shield 410; or, the bottom of the water tray 400 is provided with a drainage groove, and the bottom of the water shield 410 is embedded in the drainage groove.

[0064] Thus, by providing a guide hole at the bottom of the water-proof cover 410 to connect the steam chamber 420 with the outside of the water-proof cover 410, or by providing a drainage groove at the bottom of the water tray 400 and embedding the bottom of the water-proof cover 410 in the drainage groove, water from outside the steam chamber 420 can continuously enter the steam chamber 420 along the guide hole or drainage groove during the process of generating steam inside the steam chamber 420, replenishing the steam chamber 420 with water and preventing the steam chamber 420 from dry burning and causing safety hazards.

[0065] In a preferred embodiment of an automatic heat-preserving feeding machine, the first robotic arm 210 and the second robotic arm 220 are provided with air guiding channels (not shown in the figure). The two ends of the air guiding channels are respectively connected to a hot air device and an air guiding cavity 321. The air guiding channels are made of flexible hose material so as to move with the first robotic arm 210 and the second robotic arm 220.

[0066] Understandably, the air duct can be a soft rubber tube or a PVC hose.

[0067] Thus, by providing air guide channels inside the first robotic arm 210 and the second robotic arm 220, with both ends of the air guide channels connected to the hot air device and the air guide cavity 321 respectively, and the air guide channels being made of flexible hoses to move with the first robotic arm 210 and the second robotic arm 220, hot air can flow into the air guide cavity 321 along the air guide channels inside the first robotic arm 210 and the second robotic arm 220, without affecting the flexible movement of the first robotic arm 210 and the second robotic arm 220, thus ensuring the user's experience.

[0068] In a preferred embodiment of an automatic heat-preserving feeding machine, a second heating element (not shown) is provided at the bottom of the food holding trough 111. The second heating element is electrically connected to the controller to heat the food in the food holding trough 111. There are multiple rice spoons 320, each of which is detachably connected to the control base 310.

[0069] Thus, by providing a second heating element at the bottom of the food container 111, which is electrically connected to the controller, the food in the food container 111 is heated. There are multiple rice spoons 320, each detachably connected to the control base 310. The second heating element is used to preheat the food in the food container 111, preventing the food from getting cold and improving the user experience.
