[0002] An oven is a device used for heating and drying items, and is usually used in places such as laboratories, factories, and hospitals. The working principle of the oven is to generate heat energy through heating elements (usually electric heating wires), and then use a fan to circulate hot air into the box, making the temperature inside the box uniform. In this process, the moisture in the air is gradually volatilized, so as to achieve the effect of drying the items. The temperature of the oven can be adjusted through a control system to meet different drying requirements.

[0003] When the existing circulating oven is in use, it is difficult to adjust the internal space of the oven according to the drying amount of the items and the drying temperature, resulting in slow temperature rise during drying, which affects the drying effect. Summary of the Invention

[0004] The purpose of the utility model is to provide an improved hot air circulating oven to solve the problems put forward in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An improved hot air circulating oven, including an outer box and a heater.

An inner box is arranged in the middle of the outer box, and a placement plate is installed in the middle of the inner box. A servo motor is arranged on the top of the outer box, and a丝杆 is installed at the output end of the servo motor. A regulating component for adjusting the drying space is arranged at the top of the丝杆, and the regulating component includes a large gear, a small gear, a threaded rod, and an auxiliary frame. The outer surface of the large gear is meshed and installed with the small gear, and the threaded rod is arranged in the middle of the small gear. The auxiliary frame is threadedly installed on the outer surface of the threaded rod.

[0006] Further, guide grooves are equidistantly opened inside the inner box, and the auxiliary frame is slidably installed on the outer surface of the inner box.

[0007] Further, a door panel is installed on one side of the outer box through a hinge, and a small gear is rotatably installed at the bottom inside the outer box through a rotating shaft.

[0008] Further, a top plate is arranged above the placement plate, and the top plate is closely attached to the inner box and is rotatably connected to the丝杆.

[0009] Further, the placement plate is slidably arranged inside the inner box, and the inner box is in a "mouth" - shaped structure.

[0010] Furthermore, the placement plate is provided with auxiliary components for assisting collection, and the auxiliary components include a scraper, a connecting rod and a clamping plate.

An auxiliary frame 1104 is threaded on the outer surface of the threaded rod 1103. Items to be dried are stored inside the placement plate 9. During drying, the fan 2 is started, and the air enters the heater 4 through the air duct 3. The heater 4 is designed to heat the introduced air. The heated air enters between the outer box 1 and the inner box 6. The design of the guide groove 10 in the inner box 6 allows the hot air to be introduced into the inner box 6 for drying the items stored in the placement plate 9 inside the inner box 6. The design of the servo motor 7 drives the lead screw. The rotation of screw 8 drives the large gear 1101 to rotate. The large gear 1101 meshes with the small gear 1102, allowing the small gear 1102 to rotate using the shaft design. When rotating, the threaded rod 1103 connected to the small gear 1102 will rotate accordingly. As the threaded rod 1103 rotates, the auxiliary frame 1104 will slide upward between the outer box 1 and the inner box 6, thereby adjusting the drying area between the outer box 1 and the inner box 6.

The guide channel 10 in the inner box 6 guides the hot air into the inner box 6 to dry the items stored in the placement plate 9 inside the inner box 6. The servo motor 7 drives the lead screw 8 to rotate, and the rotation of the lead screw 8 drives the large gear 1101 to rotate. The large gear 1101 meshes with the small gear 1102, so the small gear 1102 can rotate using the shaft design. When rotating, the threaded rod 1103 connected to the small gear 1102 will rotate accordingly, and then when the threaded rod... When rod 1103 rotates, auxiliary frame 1104 slides upward between outer box 1 and inner box 6, thereby adjusting the drying area between outer box 1 and inner box 6, which is conducive to quickly raising the drying temperature and facilitating the drying of a small number of items. After drying, the door panel 12 is opened by hinge design, and the card plate 1304 is pulled outward to engage with and separate from the placement plate 9. The connecting rod 1302 and scraper 1301 connected to the card plate 1304 will slide against the inner surface of the placement plate 9, which is conducive to collecting the dried items inside the placement plate 9 and cleaning the inner surface of the placement plate 9.
