[0002] According to a patent published on the China Patent Network, the patent title is: "A Drying Mechanism for a Dryer," patent application number: 201921439548.0. It includes a dryer housing, with a fan mounting bracket bolted to the center of the end face of the housing. A fan is bolted to the end face of the mounting bracket. One end of a hot and cold air switching pipe is fixedly connected to the input end of the fan, and the other end of the pipe is fixedly connected to the output end of a heater. An air inlet is fixedly opened on the end face of the hot and cold air switching pipe. The hot and cold air switching duct is internally equipped with an air inlet cover corresponding to the air inlet. The air inlet cover is connected to the opposite side wall of the hot and cold air switching duct via a rotating rod. This utility model, by designing the air duct to be close to the rotating drum, can absorb the heat of the rotating drum, thereby saving energy. It also assists the air duct in injecting hot air from above the machine door, which can improve drying efficiency. However, in the aforementioned dryer head, material tends to accumulate in the furnace chamber during operation, leading to incomplete combustion and resulting in incomplete drying of the food, affecting the drying quality.

[0003] Therefore, it is necessary to redesign the dryer head to effectively prevent incomplete combustion that leads to incomplete drying. Utility Model Content

[0009] As a preferred embodiment of this invention, the surface of the heat dissipation conveying pipe is wound with heat dissipation fins, and the heat dissipation fins are used in conjunction with the heat dissipation conveying pipe.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. The dryer head of this utility model changes the phenomenon of incomplete combustion in traditional dryers. It adopts an induced draft fan and a large forward and reverse rotating fan to fully exhaust smoke and combust, so there will be no accumulation of materials, no incomplete combustion, no incomplete drying of food, and no impact on the drying quality.

[0012] 2. By setting angle iron, this utility model can make the induced draft fan and the furnace more stable and prevent separation.

[0013] 3. This utility model, through the setting of louvers, can more fully dissipate heat, while also preventing dust from entering the interior of the drying component.

[0014] 4. This utility model, with its sixteen heat dissipation pipes, allows for more complete exhaust of internal smoke, thus increasing its combustibility.

[0015] 5. This utility model, by wrapping heat dissipation fins around the surface of the heat dissipation conveying pipe, enables the pipe to dissipate heat more fully and avoids damage to the pipe due to excessive heat. Attached Figure Description

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.

[0020] like Figures 1 to 2 As shown, the present invention provides a dryer head, including a shell 1, a drying component 2 fixedly connected inside the shell 1, an induced draft fan 3 connected to the top left side of the drying component 2, the top of the induced draft fan 3 extending to the top of the shell 1, and large forward and reverse rotating fans 4 provided on both sides of the top of the drying component 2 and to the right of the induced draft fan 3, a heat dissipation conveying pipe 5 fixedly connected laterally inside the drying component 2, the left side of the heat dissipation conveying pipe 5 connected to the induced draft fan 3, a furnace 6 fixedly connected to the bottom left side of the inner cavity of the drying component 2, the furnace 6 being trapezoidal in shape, an ash removal port 7 opened at the bottom right side of the furnace 6, an adjustable damper 8 provided at the bottom of the furnace 6, and a manually folding door 9 provided at the top of the shell 1.

[0021] refer to Figure 2 An angle iron 10 is fixedly connected to the top of the furnace 6, and the top of the angle iron 10 is fixedly connected to the induced draft fan 3.

[0022] As a technical optimization of this utility model, the setting of angle iron 10 can make the induced draft fan 3 and the furnace 6 more stable and prevent separation.

[0023] refer to Figure 1 A louver 11 is provided at the bottom right side of the front of the outer casing 1, and the louver 11 is fixedly connected to the outer casing 1.

[0024] As a technical optimization of this utility model, the louver 11 can dissipate heat more effectively and also prevent dust from entering the interior of the drying component 2.

[0025] refer to Figure 2 There are sixteen heat dissipation pipes 5, which are evenly distributed.

[0026] As a technical optimization of this utility model, by setting the number of heat dissipation and conveying pipes 5 to sixteen, the smoke inside can be discharged more fully, thereby increasing its combustibility.

[0027] refer to Figure 2 The surface of the heat dissipation pipe 5 is wrapped with heat sinks, and the heat sinks are used in conjunction with the heat dissipation pipe 5.

[0028] As a technical optimization of this utility model, by wrapping heat dissipation fins around the surface of the heat dissipation conveying pipe 5, the pipe can dissipate heat more fully, avoiding damage to the pipe due to excessive heat.

[0029] The working principle and usage process of this utility model are as follows: First, when drying is required, the fire is started from the bottom furnace 6. Then, the fire moves from the bottom heat dissipation pipe 5 to the top heat dissipation pipe 5. The smoke in the heat dissipation pipe 5 is then sucked away by the induced draft fan 3. The hot air is blown into the drying chamber by the large fan 4 in both directions, so that the combustion can be fully completed to increase the drying quality.

[0030] In summary, this dryer head addresses the problem of incomplete combustion inherent in traditional dryers. By employing an induced draft fan 3 and a large forward and reverse rotating fan 4 to ensure thorough smoke extraction and combustion, it eliminates material buildup, prevents incomplete combustion, and ensures that the dried food is not dried properly, thus maintaining the quality of the drying process.
