Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] See attached document Figure 2 Appendix Figure 4 and attached Figure 6 This utility model provides an embodiment of an electric thermostatic forced-air drying oven, including a box body 1, which provides installation space for other components and constructs a relatively closed drying environment. An air inlet pipe 3 is connected to the right side of the outer wall of the box body 1, guiding external air into the system and providing an air source for hot air generation. A heater 4 is fixedly connected to the bottom of the outer wall of the air inlet pipe 3, providing installation support for the heating pipe 5 and the fan 6, and working together to heat and transport the air. A heating pipe 5 is fixedly connected to the top of the heater 4, heating the air entering the air inlet pipe 3, converting it into hot air. Heat pipe 5 is fixedly connected to the left side of the inner wall of air inlet pipe 3. This arrangement ensures that the air is fully heated inside the pipe. Fan 6 is fixedly connected to the right side of the inner wall of heating unit 4. Fan 6 blows air into air inlet pipe 3, promoting airflow and heat exchange. Air duct 7 is opened on the inner wall of box 1. Air duct 7 surrounds the five sides of the interior of box 1, ensuring that hot air covers the interior of box 1 in all directions, creating conditions for uniform drying of objects. Multiple air outlets 8 are opened on the rear side of the inner wall of box 1. Air outlets 8 allow hot air from air duct 7 to enter the interior space of box 1 for drying of objects. Telescopic rod 9 is fixedly connected to the middle of the rear side of the outer wall of box 1. The telescopic rod 9 moves the push block 10 through its telescopic movement, thereby adjusting the angle of the guide plate 14. The push block 10 is fixedly connected to the left end of the telescopic rod 9. The push block 10 slides on the inner wall of the rear side of the housing 1. Its plate-like structure prevents hot air leakage in the air duct 7 and ensures that hot air is discharged from the air outlet 8. The push rod 11 is fixedly connected to the front side of the push block 10. The push rod 11 moves synchronously with the push block 10, thereby driving the clamping block 12, the rotating plate 13, and the guide plate 14 to move. Multiple clamping blocks 12 are fixedly connected to the top of the push rod 11. The clamping blocks 12 cooperate with the rotating plate 13 to push the rotating plate 13 to move. The outer wall of the push rod 11 slides... Multiple rotating plates 13 are connected. The rotating plates 13 move under the push of the push rod 11, and at the same time drive the guide plate 14 to rotate. The front side of the rotating plate 13 is rotatably connected to the guide plate 14. The guide plate 14 rotates on the inner wall of the air outlet 8 under the drive of the rotating plate 13, changing the direction of the hot air blown out of the air outlet 8. Multiple guide plates 14 are rotatably connected to the inner wall of the corresponding air outlet 8, so that the hot air can be accurately blown to the object to be dried according to the needs. The middle left side of the box 1 is connected to the air outlet pipe 15. After the drying work is completed, the air outlet pipe 15 discharges excess hot air to maintain a suitable drying environment inside the box. The inside of the box 1 is equipped with a storage mechanism 2. Specifically, during operation of this electric constant temperature forced-air drying oven, external air enters through the air inlet pipe 3, and the heater 4 connected to the bottom of the air inlet pipe 3 starts immediately. Simultaneously, the fan 6 on its right side operates, blowing air into the air inlet pipe 3. At the same time, the heating tube 5 at the top of the heater 4 heats up, heating the air inside the tube to form hot air. The hot air enters the air duct 7 surrounding the five sides of the inner wall of the chamber 1 through the air inlet pipe 3, ensuring that the interior of the chamber 1 is fully heated. Subsequently, the hot air enters the interior of the chamber 1 through multiple air outlets 8 on the rear inner wall of the chamber 1. During the drying process, the user can adjust the guide plate 14 by operating the telescopic rod 9 in the middle of the rear side of the chamber 1 according to the characteristics of the items to be dried. When the telescopic rod 9 extends or retracts, it drives the left end push block 10 to slide on the inner wall of the rear side of the box 1. The plate-like structure in the middle of the push block 10 can prevent hot air leakage in the air duct 7 and ensure that hot air is discharged from the air outlet 8. When the push block 10 moves, the push rod 11 connected to its front side moves synchronously. The top clamping block 12 of the push rod 11 pushes the rotating plate 13. When the rotating plate 13 moves, the push rod 11 slides inside it. The rotating plate 13 drives the guide plate 14 to rotate on the inner wall of the air outlet 8, changing the direction of hot air blowing out, realizing precise blowing of the items to be dried, and ensuring that the items are heated evenly. After drying, the hot air inside the box 1 is discharged from the air outlet 15.

[0027] See attached document Figure 1 Appendix Figure 2 and attached Figure 5 The storage mechanism 2 includes a servo motor 201, which provides power for the operation of the entire storage mechanism 2. The bottom of the servo motor 201 is fixedly connected to the top center of the outer wall of the housing 1.

The output end of the servo motor 201 is fixedly connected to the drive rod 202, which rotates under the drive of the servo motor 201. The bottom of the drive rod 202 is slidably connected to a rotating rod 203. Through this sliding connection, the drive rod 202 can drive the rotating rod 203 to rotate along a specific trajectory. The bottom center of the inner wall of the housing 1 is fixedly connected to an insert rod 204, which provides support and positioning for the rotation of the rotating rod 203, ensuring the rotation of the rotating rod 203. The rotating rod 203 has multiple breathable plates 205 fixedly connected to its outer wall. The breathable plates 205 rotate with the rotating rod 203 and can ensure that hot air circulates in the storage mechanism 2, so that the objects placed on it are heated evenly. Multiple baffles 206 are fixedly connected to the top of the multiple breathable plates 205. The baffles 206 can prevent the objects placed on the breathable plates 205 from falling off during rotation. The top of the multiple breathable plates 205 is provided with slots 26. The slots 26 provide positions for the installation of partitions 27, which facilitates the division of the storage area. The inner walls of the multiple slots 26 are slidably connected with partitions 27. By inserting partitions 27 into the slots 26, the breathable plates 205 can be divided into multiple independent storage areas to meet the needs of partitioning the placement of objects of different types or sizes. Specifically, tilt the rotating rod 203 slightly so that the groove on the inner wall of the top of the rotating rod 203 is aligned with the strip structure at the bottom of the drive rod 202, and then move the rotating rod 203 up and straighten it. At this time, the inner wall of the bottom end of the rotating rod 203 is aligned with the insertion rod 204 at the bottom center of the inner wall of the box 1. Move the rotating rod 203 down so that the insertion rod 204 is inserted into the inner wall of the bottom end of the rotating rod 203. Then place the item to be dried on the vent plate 205 and start the equipment. When the placement mechanism 2 is started, the servo motor 201 at the top center of the outer wall of the box 1 starts to work. Its output end drives the drive rod 202 to rotate. The drive rod 202 drives the rotating rod 203, which is slidably connected at the bottom, to rotate in a circle around the insertion rod 204. All the components on the rotating rod 203 rotate synchronously. The vent plate 205 ensures that hot air circulates in the placement mechanism 2, so that the item is heated evenly. The baffle 206 at the top of the vent plate 205 prevents the item from falling. In addition, a partition 27 can be inserted into the slot 26 at the top of the vent plate 205 to divide the independent placement area and place different items in different areas to improve drying efficiency.

[0029] Working Principle: First, external air enters the system through the air inlet duct 3. The heater 4 connected to the bottom of the air inlet duct 3 starts working, and the fan 6 on the right side of the heater 4 starts, blowing air into the air inlet duct 3. At the same time, the heating tube 5 at the top of the heater 4 starts heating, heating the air blown into the air inlet duct 3 to form hot air. The heated hot air enters the air duct 7 opened on the inner wall of the chamber 1 from the air inlet duct 3. The air duct 7 is encircling, surrounding the interior of the chamber 1 on all five sides. This design ensures that the hot air can fully cover the interior of the chamber 1, providing a guarantee for uniform drying. Subsequently, the hot air enters the interior space of the chamber 1 from multiple air outlets 8 opened on the rear inner wall of the chamber 1. During the drying process, the user can guide the airflow by operating the telescopic rod 9 in the middle of the rear side of the chamber 1, according to the shape, size, and drying requirements of the items to be dried. When the angle of plate 14 is adjusted, the extension rod 9 extends or retracts, causing the push block 10 at the left end to slide on the inner wall of the rear side of the box 1. The plate-like structure in the middle of the push block 10 can prevent hot air leakage in the air duct 7 and ensure that hot air passes through the air outlet 8 effectively. At the same time, the push rod 11 connected to the front side of the push block 10 will move synchronously with the movement of the push block 10. The multiple clamps 12 on the top of the push rod 11 cooperate with the rotating plate 13. When the push rod 11 moves, the clamps 12 on the push rod 11 push the rotating plate 13 to move. While the rotating plate 13 moves, the push rod 11 slides on its inner wall. At the same time, the rotating plate 13 rotates on the rear side of the guide plate 14. Driven by the rotating plate 13, the guide plate 14 rotates on the inner wall of the air outlet 8, thereby changing the direction of the hot air blown out of the air outlet 8, ensuring that the hot air can be accurately blown to the items to be dried and heated evenly. Furthermore, before using the equipment, the placement mechanism 2 is installed. The rotating rod 203 is slightly tilted, and its top inner wall groove is aligned with the bottom strip structure of the drive rod 202. Then, the rotating rod 203 is moved upwards and straightened, so that the bottom inner wall of the rotating rod 203 is aligned with the insertion rod 204. The rotating rod 203 is then moved downwards, and the insertion rod 204 is inserted into the bottom inner wall of the rotating rod 203. After placing the object on the vent plate 205, the equipment is started. When the placement mechanism 2 is started, the servo motor 201 installed at the top center of the outer wall of the housing 1 begins to work. Its output end drives the drive rod 202 to rotate, and the drive rod 202 drives the rotating rod 203, which is slidably connected at the bottom, to rotate... The components on the rotating rod 203 rotate circumferentially around the insertion rod 204. The vent plate 205 ensures that hot air circulates within the storage mechanism 2, so that the objects placed on it are heated evenly. Multiple baffles 206 fixed to the top of the vent plate 205 prevent objects placed on the vent plate 205 from falling off during rotation. At the same time, slots 26 opened on the top of multiple vent plates 205 are used to insert partitions 27. By inserting partitions 27 into slots 26 at different positions, the vent plate 205 can be divided into multiple independent storage areas, allowing objects of different types or sizes to be placed separately, avoiding mutual interference and improving drying efficiency.
