[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Example

[0031] Reference Figures 1 to 6This is the first embodiment of the present invention. This embodiment provides an oven device, including a box body 1. Hot air components 2 are arranged on both sides of the box body 1. A flow guiding component 3 is arranged inside the box body 1. A return flow component 4 is arranged between the flow guiding component 3 and the hot air components 2. The box body 1 provides a sealed space for drying the target. The hot air components 2 provide a heat source to raise the temperature inside the box body 1 for drying. The flow guiding component 3 enables the hot air inside the box body 1 to flow along a preset path, improving the drying efficiency and ensuring that the target is dried quickly. The return flow component 4 guides the hot air back to the hot air components 2, forming a hot air circulation path.

[0032] Specifically, the airflow guiding component 3 includes a central partition 31 disposed inside the housing 1. The central partition 31 is hollow inside and has air holes 33 on its side walls. The top of the housing 1 is provided with an air cavity 34 that communicates with the central partition 31. The return flow component 4 includes an air guide hood 41 that connects the air cavity 34 and the hot air component 2. A filter frame 42 is embedded inside the air guide hood 41. Several filter plates 43 are spaced apart inside the filter frame 42. The hot air component 2 generates hot air and sends it into the housing 1. The central partition 31 guides the hot air inside the housing 1 to the air cavity 34 through the air holes 33, and then guides it back to the hot air component 2 by the air guide hood 41, forming a hot air circulation path. During this process, the hot air is filtered by the filter frame 42 and the filter plates 43, thereby effectively reducing impurities in the hot air, improving heating efficiency, and reducing the risk of product contamination.

[0033] Furthermore, the hot air assembly 2 includes an air inlet hood 21, which is connected to the side wall of the housing 1. A first fan 23 is installed inside the air inlet hood 21. An electric heating wire 24 is installed at the inner port of the air inlet hood 21. A dustproof net 22 is installed at the outer port of the air inlet hood 21. The bottom end of the air guide hood 41 is connected to the side wall of the air inlet hood 21. The first fan 23 draws outside air into the air inlet hood 21. The dustproof net 22 reduces dust particles in the drawn-in air. After the air is heated by the electric heating wire 24, it is transformed into high-temperature hot air.

[0034] The airflow guiding assembly 3 also includes side partitions 32 installed on both sides inside the housing 1. The side partitions 32 and the side of the housing 1 form a cavity to accommodate the heating wire 24. The side wall of the side partitions 32 is also provided with air holes 33 corresponding to the air holes 33 of the central partition 31. A second fan 35 with the air direction facing upward is provided inside the air cavity 34. The second fan 35 is located directly above the central partition 31. The side partitions 32 isolate the heating wire 24 from the drying space inside the housing 1. The hot air generated by the hot air assembly 2 enters the drying area of ​​the housing 1 through the air holes 33 of the side partitions 32. When the second fan 35 is activated, a negative pressure is formed inside the central partition 31. The central partition 31 accelerates the intake of hot air inside the housing 1 through the air holes 33, thereby accelerating the flow of hot air and improving the drying efficiency.

[0035] Furthermore, a bracket assembly 5 is provided between the side partition 32 and the central partition 31. Multiple sets of air vents 33 are provided and distributed at intervals from top to bottom. The bracket assembly 5 is located between the intervals of the air vents 33. The bracket assembly 5 is used to place the products that need to be dried. The air vents 33 are located above and below the bracket assembly 5, respectively, so that hot air can circulate on the top and bottom of the products that need to be dried, thereby accelerating the drying process.

[0036] The side partition 32 is provided with a guide rail 37 at the outer port of the air hole 33. A wind deflector 36 is slidably provided on the guide rail 37. The wind deflector 36 can suppress the local airflow of the air hole 33. The wind deflector 36 can adjust its position relative to the air hole 33 by moving along the guide rail 37, so as to realize the airflow adjustment of different sections of the air hole 33.

[0037] The bracket assembly 5 includes a wire mesh frame 51 and a limiting strip 52. The wire mesh frame 51 is horizontally positioned between the side partition 32 and the central partition 31. The limiting strip 52 is located at the bottom of both sides of the wire mesh frame 51 and is connected to the side partition 32 and the central partition 31 respectively. The porous structure of the wire mesh frame 51 facilitates the circulation of hot air. The wire mesh frame 51 slides along the limiting strip 52 to form a drawer-like structure, which is convenient for taking out and putting in products that need to be dried.

[0038] Preferably, rollers 53 are rotatably provided on both outer walls of the space frame 51, and positioning grooves 54 are provided on the top surface of the limiting strip 52 corresponding to the rollers 53. Handrails 55 are provided on the front outer wall of the space frame 51. The rollers 53 facilitate the movement of the space frame 51 along the limiting strip 52, and the handrails 55 facilitate the pulling of the space frame 51.

[0039] In operation, the first fan 23 draws outside air into the air inlet hood 21, and the dust filter 22 removes dust particles from the air. The air is then heated by the heating wire 24, becoming high-temperature hot air. The second fan 35 activates, creating negative pressure inside the central partition 31. The central partition 31 accelerates the intake of hot air from inside the housing 1 through the air vents 33. This hot air is guided to the air chamber 34 and then back to the hot air assembly 2 by the air guide hood 41, forming a hot air circulation path. During this process, the filter frame 42 inside the air guide hood 41 works with several filter plates 43 to form multiple filtration systems. The air must pass through several filter plates 43 sequentially during its return flow. These multiple filter plates 43 isolate the interior of the air guide hood 41 into several independent cavities, each filled with different types of filter media to effectively filter different pollutants in the air. For the treatment of dye components, preferably, the filter plate 43 isolates the interior of the air guide hood 41 into at least three independent cavities. The first cavity is filled with HEPA high-efficiency particulate filter material to adsorb and filter solid particulate impurities such as dust and powder in the air, preventing them from depositing on the heating wire 24 or re-entering the chamber 1. The second cavity is filled with activated carbon filter material to adsorb odor molecules and volatile organic compounds released from the air during the drying process, purifying the air quality and improving the comfort of the working environment. The third cavity is filled with desiccant filter material such as silica gel, molecular sieve or modified zeolite to absorb the moisture generated in the air due to the evaporation of the dried material, reducing the air humidity, thereby further improving the drying efficiency and effect. These filter materials are set in a replaceable filter frame 42 for easy maintenance, replacement or upgrading.

[0040] In summary, by combining the air guide hood 41 of the recirculation component 4 with the filter frame 42 and filter plate 43, a closed-loop hot air circuit and multiple filtration are formed, which greatly improves drying efficiency and air quality. The recirculation path allows the heated air to re-enter the heating cycle, greatly reducing heat energy waste. The filter frame 42 and filter plate 43 work together to fill HEPA particulate filter material, activated carbon and desiccant respectively, achieving triple filtration of particulate filtration, odor adsorption and moisture removal, effectively purifying the circulating air and ensuring the hygiene of the dried products and the stability of equipment operation.
