[0008] The air duct housing is provided with an air duct cover and a fixing cover. The air duct cover and the fixing cover are integrally formed or separately provided and fixed to each other. The air duct cover and the fixing cover both rely on the outer wall of the inner liner. The air duct cavity is formed between the air duct cover and the inner liner. The fixing cavity is provided inside the fixing cover.

[0009] The air duct cover is composed of an air duct back plate and left and right side plates. The air duct back plate is trapezoidal with its larger size facing the fixed cavity. The left and right side plates are respectively disposed on the left and right sides of the air duct back plate. The left and right side plates and the air duct back plate form a first air duct opening at the end away from the fixed cavity. The fan is disposed on the first air duct opening.

[0010] The fixed cover is composed of a fixed back plate, fixed left and right side plates, and a fixed end plate. The fixed back plate is rectangular. The fixed left and right side plates are respectively disposed on the left and right sides of the fixed back plate. The fixed end plate is disposed at the end of the fixed back plate away from the fan. The fixed back plate is provided with fixed left and right connecting edges at the end near the fan. Fixed cavity communication openings are provided on the fixed left and right connecting edges. The second air duct opening is connected to the fixed cavity communication opening. The connecting block is detachably assembled and disassembled with the fixed end plate and the fixed left and right connecting edges.

[0011] The connecting block is provided with a connecting block positioning edge, and the connecting block positioning edge is provided with a connecting block positioning notch. The fixed left and right side plates are provided with fixed left and right side plate notches. The connecting block positioning notch corresponds to the fixed left and right side plate notches.

[0016] This invention, through structural improvements, utilizes the combination of the duct shell, fan, heating element, and connecting block to assemble a heating device. This not only effectively simplifies the overall structure of the heating device but also reduces its production cost. Furthermore, since the heating element is disassembled and assembled via the connecting block, it simplifies the disassembly and assembly process and facilitates routine maintenance. Additionally, because the distance between the two sides of the duct cavity gradually increases towards the two ends of the fixed cavity, an air diffusion area can be formed inside the duct cavity, which is beneficial for guiding and diffusing geothermal airflow. This allows more hot airflow to diffuse and flow at designated locations and enter the inner liner, improving the flowability of the hot airflow. Moreover, since the fan and heating element are located at opposite ends of the duct cavity, they are on the same linear plane, effectively reducing the multi-angle turning of the hot airflow during flow, thereby reducing the flow rate and velocity attenuation problems that occur during the flow process and ensuring the flow rate and velocity of the hot airflow during circulation within the inner liner.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments.

An air duct cavity 4.1 is provided on the air duct shell or between the air duct shell and the inner liner 8. A fixed cavity 5.1 is provided on the air duct shell. The heating element 2 is detachably installed in the fixed cavity 5.1 through the connecting block 3. The fixed cavity 5.1 is located at one end of the air duct cavity 4.1 and the two are interconnected. The fan 1 is located at the other end of the air duct cavity 4.1 and the two are interconnected. The distance between the two sides of the air duct cavity 4.1 gradually increases towards both ends of the fixed cavity 5.1. A first inner liner air outlet 8.1 and a second inner liner air outlet 8.2 are provided on the inner liner 8 at intervals. The fan 1 is interconnected with the first inner liner air outlet 8.1. A fixed cavity opening 5.2 is provided on the fixed cavity 5.1 and is interconnected with the second inner liner air outlet 8.2 through the fixed cavity opening 5.2.

[0035] This embodiment utilizes the duct shell, fan 1, heating element 2, and connecting block 3 to assemble a heating device A. This not only effectively simplifies the overall structure of the heating device A but also reduces its production cost. Furthermore, since the heating element 2 is disassembled and assembled via the connecting block 3, the disassembly and assembly of the heating element 2 is simplified, and daily maintenance of the heating element 2 is facilitated. Additionally, because the distance between the two sides of the duct cavity 4.1 gradually increases towards both ends of the fixed cavity 5.1, an air diffusion area can be formed inside the duct cavity 4.1, which is beneficial for guiding and diffusing geothermal airflow. This allows more hot airflow to diffuse and flow at designated locations and enter the inner liner 8, improving the flowability of the hot airflow. Moreover, since the fan 1 and heating element 2 are located at opposite ends of the duct cavity 4.1, they are on the same linear plane, effectively reducing the multi-angle turning of the hot airflow during flow, thereby reducing the flow rate and velocity attenuation problems that occur during the flow process and ensuring the flow rate and velocity of the hot airflow during circulation within the inner liner 8.

[0036] The fan 1 is a centrifugal fan, and its air inlet is attached to the outer wall of the inner liner 8 and is connected to the first inner liner air inlet 8.1. The air outlet of the fan 1 faces the air duct shell and is connected to the air duct cavity 4.1.

[0039] In this embodiment, the first inner liner vent 8.1 is a circular opening and is located on the back of the inner liner 8. The second inner liner vent 8.2 is provided with a plurality of elongated holes. The plurality of elongated holes are spaced apart along the left and right direction of the inner liner 8 on the back of the inner liner 8. The air duct shell is correspondingly fixed to the back of the inner liner 8.

At the same time, the protective mesh cover 9 is fixedly assembled to the inner wall of the inner liner 8 using fasteners, and after assembly, it covers the first inner liner air vent 8.1, thereby covering and protecting the first inner liner air vent 8.1 and preventing users or objects to be disinfected from contacting the heating device A through the first inner liner air vent 8.1.

After forming, the air duct cover 4 and the fixing cover 5 are fixed together by welding.

[0044] In addition, the air duct cover 4 and the fixing cover 5 can be made of metal material with a thinner thickness, while the connecting block 3, which plays a role in connecting and fixing, is made of metal material with a thicker thickness than the air duct cover 4 and the fixing cover 5, which can further reduce the production and processing costs.

[0045] Both the air duct cover 4 and the fixing cover 5 rely on the outer wall of the inner liner 8. The air duct cover 4 and the inner liner 8 form an air duct cavity 4.1, and the fixing cover 5 is provided with a fixing cavity 5.1.

The fan connecting edge 4.9 and the fan 1 side plate are attached to and fixedly matched, thereby realizing the cooperation between the air duct housing A and the fan 1, and also preventing the air in the air duct cavity 4.1 from leaking out through the position between the air duct housing A and the fan 1.

[0050] The fixed cover 5 consists of a fixed back plate 5.3, fixed left and right side plates 5.4, and fixed end plate 5.5. The fixed back plate 5.3 is rectangular.

The fixed connecting edge 4.10 is attached to and welded to the fixed back plate 5.3 and the fixed left and right connecting edges 5.6, thereby realizing the cooperation between the air duct cover 4 and the fixed cover 5, and also preventing the air in the air duct cavity 4.1 from leaking out through the position between the air duct cover 4 and the fixed cover 5.

[0052] The connecting block 3 is provided with a connecting block positioning edge 3.1, and the connecting block positioning edge 3.1 is provided with a connecting block positioning notch 3.2. The left and right side plates 5.4 are provided with a fixing left and right side plate notch 5.8.

[0053] During assembly, the heating element 2 is positioned at its end on the notch 5.8 of the left and right side plates via the positioning step 2.2. Then, the connecting piece 3 is fixed to the fixing cover 5, and the positioning notch 3.2 of the connecting block acts on the positioning step 2.2, thus completing the installation of the heating element 2. Furthermore, the end of the heating element 2's end seat 2.1 extends at least beyond the notch 5.8 of the left and right side plates and the positioning notch 3.2 of the connecting block, facilitating connection of the heating element 2 to the power cord and obtaining operating power.
