Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0032] Example 1:

[0033] like Figure 1-6 As shown, a rice cooker inner pot spraying device includes a column 2 supported on the ground by a base 1, an electric turntable 3 rotatably connected to the outer wall of the column 2, and a top frame 4 fixedly connected to the top of the column 2.

[0034] The electric turntable 3 has multiple clamping components arranged radially inside. The clamping components include a fixed plate 5 and a limiting plate 9. The inner wall of the fixed plate 5 has multiple radially arranged straight grooves 6. The inner wall of the straight grooves 6 is slidably fitted with guide rods 8. The top of the guide rods 8 is fixedly connected to an arc-shaped clamping plate 7. The inner wall of the limiting plate 9 has multiple inclined grooves 10 with the same number as the straight grooves 6. The guide rods 8 are slidably limited and fitted to the inner wall of the inclined grooves 10.

[0035] The electric turntable 3 rotates intermittently. Its principle is existing technology and well known to those skilled in the art. No creative work has been done on it in this embodiment, so it will not be described in detail.

[0036] The inner liner is placed on top of the fixed plate 5. When the limiting plate 9 rotates, the guide rod 8, in conjunction with the inclined groove 10, causes all the arc-shaped clamping plates 7 to move centripetally along the inner wall of the straight groove 6, thereby achieving centripetal clamping of the inner liner.

[0037] This device, by setting up a straight groove 6, a guide rod 8, and an inclined groove 10, can use the arc-shaped clamping plate 7 to achieve centripetal clamping of the inner liner with the cooperation of each component. This prevents the inner liner from shifting or falling off as the electric turntable 3 rotates, which would affect the spraying efficiency. It can also ensure the consistency of the inner liner's position and ensure the quality of subsequent spraying.

[0038] In this embodiment, the bottom of the electric turntable 3 is slidably fitted with a plurality of racks 13, the same number as the limiting disk 9, and the outer wall of the limiting disk 9 is provided with teeth that mesh with the racks 13.

[0039] The bottom of the electric turntable 3 is fixedly connected with multiple mounting plates 11, the same number as the rack 13, and springs 12 are fastened to the opposite side of the mounting plates 11 and the rack 13.

[0040] A guide ring 14 is fixedly connected to the outer wall of the column 2. Two protrusions 15 are provided on the guide ring 14. The rack 13 contacts and engages with the guide ring 14 and the protrusions 15.

[0041] The electric turntable 3 is started to rotate intermittently. When a set of clamping components rotates to the loading station, the corresponding rack 13 moves to one of the protrusions 15. The protrusion 15 pushes the rack 13 to move outward. The rack 13 drives the limiting plate 9 to rotate. Under the limitation of the inclined groove 10 and the straight groove 6, the guide rod 8 drives the arc-shaped clamping plate 7 to move outward, increasing the distance between the arc-shaped clamping plates 7, thus facilitating the placement of the inner liner. Subsequently, the set of clamping components drives the inner liner to rotate and move to the spraying station for spraying. During this process, the rack 13 disengages from the protrusion 15, and the spring 12 uses its own elasticity to push the rack 13 to move inward, causing the limiting plate 9 to reverse. With the cooperation of 10 and straight groove 6, guide rod 8 drives arc clamping plate 7 to move centripetally to clamp the inner liner. After spraying, clamping assembly drives the inner liner to rotate to the drying station for drying. At this time, rack 13 still moves along the outer wall of guide ring 14, and arc clamping plate 7 always maintains the clamping state. After drying, clamping assembly drives the inner liner to the unloading station. At this time, rack 13 moves to another protrusion 15. Protrusion 15 pushes rack 13 to move outward. Limiting plate 9 rotates, and the inclined groove 10 and straight groove 6 make guide rod 8 drive arc clamping plate 7 to move outward, increasing the distance between arc clamping plates 7, making it easier to remove the inner liner.

[0042] This device, by setting up a rack 13, a guide ring 14, and a protrusion 15, with the cooperation of each component, can, on the one hand, use the rotation of the electric turntable 3 to achieve the clamping and loosening of the arc-shaped clamping plate 7 on the inner liner, reducing the arrangement of the power source and simplifying the control logic. On the other hand, it can improve the continuity of the entire workflow, eliminating the need for machine downtime and improving spraying efficiency.

[0043] In this embodiment, a fan 16 and a spraying assembly 18 are respectively provided at the bottom of the top frame 4, and an electric push rod 17 is fixed to the top of the top frame 4 by bolts.

[0044] The spraying assembly 18 includes a connecting plate 19 and a hollow rod 21. The telescopic end of the electric push rod 17 passes through the top frame 4 and is rotatably connected to the inner wall of the connecting plate 19. The hollow rod 21 is fixedly connected to the bottom of the connecting plate 19, and multiple spray nozzles 22 are fixedly connected and communicated to the inner wall of the bottom of the hollow rod 21.

[0045] The blower 16 and the spraying assembly 18 correspond to the drying station and the spraying station, respectively. When the inner tank moves to the spraying assembly 18, the electric push rod 17 drives the connecting plate 19 to lower the hollow rod 21 and the nozzle 22. The nozzle 22 descends into the inner tank to perform the spraying operation. After the spraying is completed, the electric push rod 17 drives the connecting plate 19 to raise the hollow rod 21 and the nozzle 22. The electric turntable 3 rotates to move the inner tank below the blower 16 to achieve drying.

[0046] Example 2:

[0047] A rice cooker inner pot spraying device, this embodiment is based on embodiment 1 with the following improvements, such as... Figure 5 , 6 As shown:

[0048] The bottom of the top frame 4 is fixedly connected to a hollow cylinder 20. The inner wall of the hollow cylinder 20 is provided with a spiral groove 23, and the inner wall of the hollow cylinder 20 at the bottom of the spiral groove 23 is provided with an annular groove 24 that communicates with the spiral groove 23.

[0049] The inner wall of the connecting plate 19 is fixedly connected to a ball-head limiting rod 25 that cooperates with the spiral groove 23 and the annular groove 24 for limiting.

[0050] When the electric actuator 17 pushes the connecting plate 19 down, with the cooperation of the spiral groove 23 and the ball head limiting rod 25, the connecting plate 19 drives the hollow rod 21 and the nozzle 22 to rotate and descend. When the ball head limiting rod 25 moves into the annular groove 24, the electric actuator 17 is closed. The connecting plate 19, the hollow rod 21 and the nozzle 22 continue to rotate under the action of inertia, and the nozzle 22 starts the spraying operation.

[0051] This device, by setting up a spiral groove 23, an annular groove 24 and a ball head limiting rod 25, uses the cooperation of the three to realize the rotational descent of the connecting plate 19, hollow rod 21 and nozzle 22, which can reduce the arrangement of power source, and the rotational spraying can further improve the uniformity of spraying and improve the production quality of inner liner.

[0052] Working principle: This device is equipped with four stations, namely the loading station, the spraying station, the drying station, and the unloading station. The two protrusions 15 correspond to the loading and unloading stations respectively, and the fan 16 and the spraying component 18 correspond to the drying station and the spraying station respectively.

[0053] Taking an inner liner spraying operation as an example: The electric turntable 3 is started and rotates intermittently. When the fixed plate 5 rotates to the loading station, the corresponding rack 13 is located at one of the protrusions 15. The protrusion 15 pushes the rack 13 outward, causing the rack 13 to rotate the limiting plate 9. Under the limitation of the inclined groove 10 and the straight groove 6, the guide rod 8 drives the arc-shaped clamping plate 7 to move outward, increasing the distance between the arc-shaped clamping plates 7, thus facilitating the placement of the inner liner. Then, the electric turntable 3 rotates again, driving the fixed plate 5 to the spraying station. The electric push rod 17 is started. With the cooperation of the spiral groove 23 and the ball head limiting rod 25, the electric push rod 17 drives the connecting plate 19 to rotate and lower the hollow rod 21 and the nozzle 22. When the ball head limiting rod 25 moves into the annular groove 24, the electric push rod 17 is turned off. The push rod 17, connecting plate 19, hollow rod 21, and nozzle 22 continue to rotate under inertia. The nozzle 22 descends into the inner liner to achieve rotary spraying, improving the uniformity of spraying. After spraying, the electric push rod 17 drives the connecting plate 19 to lift the hollow rod 21 and nozzle 22. The electric turntable 3 rotates again, moving the fixed plate 5 to the drying station, which is below the fan 16. The fan 16 is then started to dry the inner liner. Finally, the electric turntable 3 drives the fixed plate 5 to rotate to the unloading station. At this time, the rack 13 is located at another protrusion 15. The protrusion 15 pushes the rack 13 to move outward. The limiting plate 9 rotates, and the inclined groove 10 and straight groove 6 cause the guide rod 8 to move the arc-shaped clamping plate 7 outward, increasing the distance between the arc-shaped clamping plates 7, making it easier to remove the inner liner.

[0054] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
