[0019] As shown in Figures 1 to 3, an embodiment of this utility model provides an ethylene oxide sterilization preheating chamber, comprising a first segmented box 1, a second segmented box 2, and a third segmented box 3, sequentially assembled from left to right. These three segments form a sealed, hollow rectangular preheating chamber. A preheating chamber door 10 is located on the side of the first segmented box 1 away from the third segmented box 3, specifically on the left side wall of the first segmented box 1, sealing the preheating chamber. An equipment box 4 is mounted on the third segmented box 3, located on its right outer side wall. The equipment box 4 contains a circulating fan 40 and a humidifying device 41 communicating with the interior of the third segmented box 3. The third segmented box 3 also includes a heating chamber for heating air. The air outlet of the circulating fan 40 is detachably connected to an air outlet pipe 42 that sequentially connects to the heating chamber, the interior of the third segment box 3, the interior of the second segment box 2, and the interior of the first segment box 1. The air intake of the circulating fan 40 is detachably connected to an air intake pipe 43 that sequentially connects to the interior of the third segment box 3, the interior of the second segment box 2, and the interior of the first segment box 1. Preferably, both the air outlet pipe 42 and the air intake pipe 43 are composed of multiple detachably connected pipes, which are detachably connected together by flanges. This allows the air outlet pipe 42 and the air intake pipe 43 to be disassembled into multiple sections for transportation, which is very convenient. A humidity sensor 6 is also provided on the inner wall of the third segment box 3. The humidity sensor 6 is electrically connected to the humidification device 41. Preferably, the inner walls of the first segment box 1, the second segment box 2, and the third segment box 3 are filled with insulation material, such as rock wool or glass wool.

[0020] By transporting the first segment box 1, the second segment box 2, the third segment box 3, the air outlet duct 42, and the air intake duct 43 separately to the sterilization workshop and then assembling them, the space limitations of the sterilization workshop and aisles are avoided. At the same time, the volume of the preheating chamber is expanded by increasing the number of second segment boxes 2. For example, in this embodiment, two second segment boxes 2 are set to increase the volume of the preheating chamber. Compared with on-site construction of the preheating chamber, the preheating chamber can be put into use more quickly by assembling and assembling, and it can be disassembled for easy relocation.

[0021] Further improvements, as shown in Figures 1 and 3, include protrusions 7 on both the two opposite outer walls of the first segment box 1 and the two opposite outer walls of the second segment box 2. Specifically, protrusions 7 are provided on both the front and rear outer walls of the first segment box 1, and also on both the front and rear outer walls of the second segment box 2. A protrusion groove 70 is provided on the surface of the protrusion 7 near the third segment box 3, and the protrusion groove 70 is located on the right end face of the protrusion 7. The protrusion groove 70 has a rectangular structure. Two insertion rods 71 ​​are provided on both opposite outer walls of the second segment box 2, respectively, to be inserted into the corresponding protrusion grooves 70 on the first segment box 1. Specifically, two insertion rods 71 ​​are respectively located on the front and rear outer walls of the second segment box 2, and are respectively inserted into the two protrusion grooves 70 on the first segment box 1. The two insertion rods 71 ​​on the right side of the second segment box 2 are respectively inserted into the left side. In the two protrusion slots 70 on the second segment box 2, the two opposite outer walls of the third segment box 3 are provided with matching insertion rods 71 ​​that are inserted into the corresponding protrusion slots 70 on the second segment box 2. That is, the two insertion rods 71 ​​are respectively set on the front and rear outer walls of the third segment box 3. At this time, the two insertion rods 71 ​​are respectively matched and inserted into the two protrusion slots 70 on the right side of the second segment box 2. The outer wall of the protrusion 7 is provided with bolts 73 that pass through the protrusion 7 and are threadedly connected to the corresponding insertion rods 71. The insertion rods 71 ​​are provided with threaded holes, and the protrusion 7 is provided with through holes coaxial with the threaded holes. The bolts 73 are set on any one of the outer walls of the left, upper, and lower outer walls of the protrusion 7. The bolts 73 pass through the through holes and are threadedly connected to the threaded holes, thereby fixing the insertion rods 71 ​​and the protrusion 7, so that the first segment box 1, the second segment box 2, and the third segment box 3 can be spliced ​​and fixed.

[0022] As shown in Figures 1 and 3, a further improvement is made by providing a chamfer 72 on the insertion rod 71 for guiding insertion. The chamfer 72 is located at the left end of the insertion rod 71. The chamfer 72 guides the insertion of the first segment box 1, the second segment box 2 and the third segment box 3, thus facilitating their assembly.

[0023] Further improvements are shown in Figures 2 and 3. An annular insertion wall 8 is provided on the end face of the second segment box 2 opposite to the first segment box 1. The insertion wall 8 is square annular. An insertion groove 80 matching the insertion wall 8 is provided on the end face of the second segment box 2 opposite to the third segment box 3. An insertion groove 80 is also provided on the end face of the first segment box 1 opposite to the third segment box 3. An insertion wall 8 is also provided on the end face of the third segment box 3 opposite to the first segment box 1. A sealing ring 9 is provided at the bottom of the insertion groove 80. The sealing ring 9 is also square annular. The sealing performance of this preheating chamber is increased by the insertion wall 8, the insertion groove 80 and the sealing ring 9.

[0024] Further improvements, as shown in Figures 2 and 3, include that the inner wall of the insertion wall 8 is coplanar with the inner wall of the preheating chamber, and that the insertion groove 80 is open at one end near the inner side of the preheating chamber, i.e., the right end of the inner wall of the first segment box 1 and the second segment box 2 is recessed outward to form a stepped insertion groove, which facilitates the processing of the insertion wall 8 and the insertion groove 80.

[0025] Further improvements, as shown in Figures 1, 2, and 3, include air inlets on the top surfaces of the first segmented box 1, the second segmented box 2, and the third segmented box 3. The air outlet pipe 42 is detachably connected to multiple air inlets. Air outlets are located near the bottom of the preheating chamber on the sides of the first segmented box 1, the second segmented box 2, and the third segmented box 3. The suction pipe 43 is detachably connected to multiple air outlets. Airflow within the preheating chamber is achieved through the air inlets, air outlets, air outlet pipe 42, and suction pipe 43, resulting in uniform airflow and preventing localized temperature and humidity fluctuations. The air inlet of the air outlet pipe 42 is detachably connected via a flange, and the air outlet of the suction pipe 43 is also detachably connected via a flange. The detachable connection of the suction pipe 42 and the air outlet pipe 43 facilitates transportation during the installation or relocation of the preheating chamber.

[0026] As shown in Figures 1 and 2, the heating chamber includes a heating box 5 installed on the third segment box 3. An electric heating tube 50 is installed inside the heating box 5 to raise the temperature of the air inside the heating box 5. Then, the air is circulated between the heating box 5 and the preheating chamber by the circulating fan 40, the air outlet pipe 42 and the air intake pipe 43, thereby raising the temperature inside the preheating chamber.

[0027] As further improved, as shown in Figures 1 and 2, the humidification device 41 is a steam generator or atomizer, which maintains the humidity in the preheating room.

[0028] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
