[0033] Please refer to Figure 1 and Figure 2As shown, this application provides a fanless disinfection cabinet, including an outer shell assembly 1 and an inner liner 2 disposed inside the outer shell assembly 1. The outer shell assembly 1 includes a shell and a door panel. A first air inlet 5 is provided at the bottom of the outer shell assembly 1. The inner liner 2 is used to accommodate items to be disinfected. The disinfection cabinet does not include a fan. The longitudinal cross-sectional area of ​​the inner liner 2 is greater than its transverse cross-sectional area, that is, the height of the inner liner 2 is greater than its width. An air intake mechanism is provided in the cavity between the outer shell assembly 1 and the inner liner 2. The air intake mechanism is located at the lower part of the inner liner 2. Specifically, the air intake mechanism includes an airflow channel. The airflow channel is provided with a heating component for heating the gas in the airflow channel. The airflow channel is connected to the first air inlet 5 and the bottom of the inner liner 2 respectively. An air outlet mechanism for discharging hot air from the inner liner 2 is also provided at the upper part of the inner liner 2. This application sets the longitudinal cross-sectional area of ​​the inner liner 2 to be larger than the transverse cross-sectional area, making the inner liner 2 form a long and narrow cavity similar to a "chimney". This significantly increases the height of the hot air rising path. At the same time, the first air inlet 5 and the air intake mechanism are located at the bottom of the inner liner 2, and the air outlet mechanism is located at the top of the inner liner 2. This lengthens the height distance between the airflow starting point and the airflow outlet. The hot air in the inner liner 2 rises due to its lower density, and the cold air at the bottom is continuously replenished through the first air inlet 5, forming a vertical airflow circulation that does not require external power. This improves the natural convection speed and accelerates the efficiency of hot air discharge. The disinfection cabinet does not have a fan, which can eliminate the noise of fan operation at the source and avoid noise interference to users. The chimney effect does not require additional electricity to drive the airflow, which can significantly reduce the power consumption of the whole machine and make it more energy-saving and environmentally friendly.

[0034] Please refer to the following: Figure 4 and Figure 5As shown, the air intake mechanism includes a first air intake mechanism, the airflow channel includes a first airflow channel 14, and the heating component includes a first heating component 16. The first heating component 16 is disposed in the first airflow channel 14 for heating the gas in the first airflow channel 14. The first air intake mechanism includes a first housing, the first airflow channel 14 is disposed in the inner cavity of the first housing, a first air intake 6 is disposed at the bottom of the first housing, and a second air intake is disposed at the bottom of the inner liner 2. Specifically, the second air intake includes a first hollow structure 7 and a second hollow structure 8. The first hollow structure 7 is disposed directly opposite the first air intake 6, and the second hollow structure 8 is disposed on the side of the first air intake 6; the area ratio of the first hollow structure 7 to the second hollow structure 8 is less than 1:4. More specifically, the inner liner 2 includes a top wall 21, two first side walls 22, a bottom wall, and a second side wall 23. The second side wall 23 is located on the back of the inner liner 2. The top wall 21 and the bottom wall are disposed opposite each other, the two first side walls 22 are disposed opposite each other, and the second side wall 23 is located between the two first side walls 22. Both the first hollow structure 7 and the second hollow structure 8 are located on the bottom wall. The first hollow structure 7 consists of several spaced circular holes extending from the outer side of the bottom wall towards the second side wall 23. The second hollow structure 8 consists of several spaced elongated holes extending from the outer side of the bottom wall towards the second side wall 23. The first hollow structure 7 faces the first air inlet 6, forming a vertical directional airflow that rises rapidly under the chimney effect. The second hollow structure 8, through side air intake, balances the local negative pressure generated by the high-speed airflow of the first hollow structure 7, preventing airflow turbulence due to pressure imbalance and ensuring that hot air is evenly diffused to the dead corners at the edges of the inner liner 2. The area ratio of the first hollow structure 7 to the second hollow structure 8 is less than 1:4. By limiting the air intake of the first hollow structure 7 to increase the flow rate, and by ensuring sufficient air intake for the second air inlet through the second hollow structure 8, the disinfection cabinet achieves high-flow-rate core disinfection and large-volume coverage.

[0035] Furthermore, the first heating component 16 is disposed at the bottom of the first housing. Gaps are provided between the first heating component 16 and the inner liner 2, and between the first heating component 16 and the bottom of the first housing. A graphene layer is disposed on the side of the first heating component 16 facing the inner liner 2. Specifically, the first heating component 16 is a heating tube, used to heat the gas entering the first airflow channel 14. The heated gas enters the inner liner 2 through the first perforated structure 7 and the second perforated structure 8. By placing the first heating component 16 at the bottom of the first housing, the hot gas flows from bottom to top, forming a chimney effect and enhancing the airflow in the inner liner 2. Gaps are provided between the first heating component 16 and the inner liner 2, and between the first heating component 16 and the bottom of the first housing. These gaps allow the gas in the first airflow channel 14 to fully contact the first heating component 16, improving heating efficiency. More specifically, the first heating component 16 is a plate-like structure with arc-shaped surfaces on both sides. The arc-shaped surfaces guide the airflow, preventing obstruction and accelerating airflow. The graphene layer can accelerate thermal radiation and further improve thermal conversion efficiency.

[0036] Furthermore, the air intake mechanism also includes a second air intake mechanism, the airflow channel also includes a second airflow channel 15, and the heating component includes a second heating component 17. The second heating component 17 is disposed in the second airflow channel 15 and is used to heat the gas in the second airflow channel 15. The second air intake mechanism includes a second housing, the second airflow channel 15 is disposed in the inner cavity of the second housing, a third air intake 9 is disposed at the bottom of the second housing, and a fourth air intake is disposed at the bottom of the inner liner 2. Specifically, the fourth air intake includes a third hollow structure 10 and a fourth hollow structure 11. The third hollow structure 10 is disposed directly opposite the third air intake 9, and the fourth hollow structure 11 is disposed on the side of the third air intake 9. The area ratio of the third hollow structure 10 to the fourth hollow structure 11 is less than 1:4. Both the third hollow structure 10 and the fourth hollow structure 11 are disposed on the bottom wall of the inner liner 2. The third hollow structure 10 consists of several spaced circular holes that extend from the outer side of the bottom wall toward the second side wall 23. The fourth perforated structure 11 consists of several elongated holes spaced apart, extending from the outer side of the bottom wall towards the second side wall 23. The third perforated structure 10 faces the third air inlet 9, forming a vertically directional airflow that rises rapidly under the chimney effect. The fourth perforated structure 11, through side air intake, balances the local negative pressure generated by the high-speed airflow of the third perforated structure 10, preventing airflow turbulence due to pressure imbalance and ensuring that hot air is evenly diffused to the dead corners at the edges of the inner liner 2. The area ratio of the third perforated structure 10 to the fourth perforated structure 11 is less than 1:4. By limiting the air intake of the third perforated structure 10 to increase the flow rate, and by ensuring sufficient air intake for the fourth air inlet through the fourth perforated structure 11, the disinfection cabinet achieves high-flow-rate core disinfection and large-volume coverage.

[0037] Preferably, the second heating component 17 is disposed at the bottom of the second housing, with gaps between the second heating component 17 and the inner liner 2, and between the second heating component 17 and the bottom of the second housing. A graphene layer is disposed on the side of the second heating component 17 facing the inner liner 2. The structure of the second heating component 17 is the same as that of the first heating component 16, and will not be described in detail here.

[0038] The first air inlet 5 is located in the middle of the bottom of the outer casing assembly 1, and the first air inlet 6 and the third air inlet 9 are respectively located on both sides of the first air inlet 5. Outside air enters the outer casing assembly 1 through the first air inlet 5, and then splits into two paths, entering the first airflow channel 14 and the second airflow channel 15 through the first air inlet 6 and the third air inlet 9 respectively. Then, it enters the inner liner 2 through the second air inlet and the fourth air inlet respectively.

[0039] like Figure 4 and Figure 5 As shown, in one embodiment of this disclosure, the air outlet mechanism includes a first air outlet 19 and a second air outlet 20. The first air outlet 19 is disposed on the second side wall 23 of the inner liner 2, and the height of the first air outlet 19 is greater than one-third of the height of the second side wall 23. The second air outlet 20 is disposed on the top wall 21. Specifically, the first air outlet 19 is a hollow structure arranged along the width direction of the second side wall 23, and the second air outlet 20 includes four air outlet structures arranged along the width direction of the inner liner 2. Specifically, the air outlet structure consists of three spaced through holes. The area of ​​the first air outlet 19 is larger than that of the second air outlet 20. The first air outlet 19 is the main air outlet channel. The height of the first air outlet 19 is greater than one-third of the height of the second side wall 23. Setting the height of the first air outlet 19 higher can lengthen the airflow path in the inner liner 2. In addition, the second air outlet 20 can further exhaust the hot air accumulated at the top and prevent the hot air from stagnating. The first air outlet 19 and the second air outlet 20 work together to enhance the chimney effect.

[0040] Please refer to Figures 2-4As shown in the figure, a cover plate assembly 3 is provided on the top of the outer shell assembly 1, and a plurality of exhaust ports 13 are provided on the cover plate assembly 3. The cover plate assembly 3 includes a square annular frame 12 and a first cover plate. The first cover plate covers the upper part of the square annular frame 12, and there is a gap between the first cover plate and the square annular frame 12. The plurality of exhaust ports 13 are provided on three side frames of the square annular frame 12. Specifically, the square annular frame 12 has a "hui" - shaped structure, which includes four side frames. Two side frames are respectively located above the first side wall 22 of the inner container 2, one side frame is located above the second side wall 23 of the inner container 2, and another side frame is located above the disinfection cabinet door panel. The exhaust ports 13 are provided on the two side frames above the first side wall 22 and the side frame above the second side wall 23. The hot air in the inner container 2 enters the space between the inner container 2 and the outer shell assembly 1 through the first air outlet part 19 and the second air outlet part 20, and then is discharged through the exhaust ports 13. A gap is provided between the first cover plate and the square annular frame 12 to facilitate exhaust.
