Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Refer to Figures 1 to 5 , a drying device, including a box body 100. A partition 200 is arranged inside the box body 100 to divide the space inside the box body 100 into a first chamber 110 and a second chamber 120. The first chamber 110 is located below the second chamber 120. A heating component is installed in the first chamber 110, and the second chamber 120 is used to place the material to be dried. The heating component can heat the second chamber 120 to dry the material.

[0026] The heating component includes an air supply assembly 500 and an air duct 300. The air supply assembly 300 is a fan or a blower. The air duct 300 includes a cylinder body 310. The cylinder body 310 is a columnar structure that is through up and down. A first opening 311 is provided on the side wall of the cylinder body 310. A connection cover 320 extends outward at the first opening 311. The air outlet of the air supply assembly 500 is connected and fixed to the connection cover 320, so that the air supply assembly 500 can blow air into the air duct 300. At the same time, a third opening 210 is provided on the partition 200. The top of the air duct 300 passes through the third opening 210 and extends into the second chamber, so that the air flow in the air duct 300 can flow into the second chamber.

[0027] A support member is provided on the inner wall of the air duct 300. The support member is located above the first opening 311. The support member includes a support plate 330. There are two support plates 330 and they are symmetrically arranged. A protrusion 331 is provided on the support plate 330. A heating component is installed in the air duct 300. The heating component is a TCP component. The heating component is placed on the protrusion 331. When the air flow passes through the air duct 300, heat exchange will occur with the heating component, so as to heat the air flow passing through the air duct 300, so that the hot air can enter the second chamber to heat the second chamber.

[0028] A third opening 210 is provided on the partition plate 200, and a notch 340 is provided at the top of the air duct 300. The top of the air duct 300 passes through the third opening 210 and extends into the second chamber, so that the notch 340 is placed in the second chamber. A top cover 400 is provided at the top of the air duct 300. The top cover 400 covers the top of the air duct 300. At the same time, a second opening 430 is provided on the top cover 400. The position of the second opening 430 corresponds to that of the notch 340. The air in the air duct 300 flows into the second chamber after passing through the notch 340 and the second opening 430.

[0029] The top cover 400 includes a top plate 410 and side plates 420 disposed at the edge of the top plate 410. The second opening 430 extends from the top plate 410 to the side plates 420, so that hot air can flow out from both the top surface and the side surface of the top cover 400, thereby ensuring the uniformity and efficiency of hot air diffusion.

[0030] Positioning posts 332 are provided on both of the two support plates 330. A first positioning hole 333 is provided at the top of the positioning post 332. Two positioning grooves 440 corresponding to the positions of the positioning posts 332 are provided on the top cover 400. A second positioning hole 441 is provided at the bottom of the positioning groove 440. The top cover 400 is fixed to the air duct 300 by a fastener that passes through the second positioning hole 441 and is screwed into the first positioning hole 333.

[0031] A temperature sensor 220 is provided on one side of the partition plate 200 facing the second chamber 120. The temperature in the second chamber 120 can be measured in real time through the temperature sensor 220. Multiple temperatures are set in the control system of the drying device so that the temperature in the drying device can be divided into multiple gears. When the temperature measured by the temperature sensor 220 is less than the temperature set for the current gear, the heating component is turned on to heat the second chamber 120 to raise the temperature of the second chamber 120; when the temperature measured by the temperature sensor is greater than the temperature set for the current gear, the heating component is turned off to lower the temperature in the second chamber 120. This process is repeated so that the temperature in the second chamber 120 is maintained within the set temperature range.

[0032] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
