[0026] Specifically, the defogging component 2 includes a driving motor 201 installed on one side inside the installation box 105. A first screw rod 202 is arranged at the output end of the driving motor 201 and inside the heating box 103. A driving wheel 203 is fixedly connected to the outside of the first screw rod 202 and at the top of the heating box 103. Installation bottom plates 207 are fixedly connected to both sides inside the heating box 103 and at positions below the observation window 104. A second screw rod 205 is rotatably connected to one end of the top of the installation bottom plate 207 away from the first screw rod 202. A driven wheel 206 is fixedly connected to the upper part outside the second screw rod 205 and at the top of the heating box 103. The driving wheel 203 and the driven wheel 206 are connected and installed through a transmission belt 204. A limiting slide rod 210 is fixedly installed at the center of the top of the installation bottom plate 207. Slide rings 208 are installed on the outside of both the first screw rod 202 and the second screw rod 205 through threaded connections. A cleaning brush 209 is arranged between the two slide rings 208. The cleaning brush 209 is slidably arranged on the outside of the limiting slide rod 210, so as to ensure the stability of the cleaning brush 209 during the defogging process. One side of the cleaning brush 209 close to the observation window 104 is provided with a water-absorbing cotton cloth. The cleaning brush 209 is in contact with but not connected to the observation window 104. During the sterilization and drying process, when fog appears on the observation windows 104 on both sides of the heating box 103 and affects the observation, the worker can control the start of the driving motor 201. The driving motor 201 works to drive the first screw rod 202 to rotate. Thus, under the action of the driving wheel 203 and the transmission belt 204, the driven wheel 206 and the second screw rod 205 are driven to rotate. Furthermore, the slide rings 208 outside the first screw rod 202 and the second screw rod 205 can be driven to move up and down, and then the cleaning brush 209 can be driven to move up and down on one side of the observation window 104, so as to clean the fog generated on the surface of the observation window 104, thus facilitating the observation of the drying situation inside the drying oven during the work process.

[0027] Furthermore, the air filter 108 is detachably installed between the ventilation pipe 106 through bolts. Under the action of the air filter 108, the air entering and leaving can be effectively filtered during ventilation, ensuring the air quality to a certain extent. At the same time, the air filter 108 can be replaced regularly through bolts to ensure the subsequent filtering effect.

[0028] Furthermore, the traveling wheels 101 are universal wheels with a self-locking function. Under the action of the traveling wheels 101, the flexibility of using the sterilization drying oven can be improved to a certain extent.

[0029] Furthermore, the output end of the driving component 110 is connected and installed with the conveying component 107. Control the driving component 110 to work to drive the conveying component 107 to convey the items to be sterilized and dried into the heating box 103. Before that, control the far-infrared heater 109 to work to heat the inside of the heating box 103, so that the items to be dried can be heated and dried after entering the heating box 103.

[0030] The working process of the utility model is as follows: when using this tunnel sterilization oven, first place the items to be sterilized and dried on the top of the conveying component 107, and then control the driving component 110 to work to drive the conveying component 107 to convey the items to be sterilized and dried into the heating box 103. Before that, control the far-infrared heater 109 to work to heat the inside of the heating box 103, so that the items to be dried can be heated and dried after entering the heating box 103. And during the sterilization and drying process, when fog appears on the observation windows 104 on both sides of the heating box 103 and affects the observation, the worker can control the driving motor 201 to start. The driving motor 201 works to drive the first screw rod 202 to rotate, and thus drives the driven wheel 206 and the second screw rod 205 to rotate under the action of the driving wheel 203 and the transmission belt 204. Furthermore, the sliding ring 208 outside the first screw rod 202 and the second screw rod 205 can be driven to move up and down, and then the cleaning brush 209 can be driven to move up and down on one side of the observation window 104, so as to clean the fog generated on the surface of the observation window 104, thus facilitating the observation of the drying situation inside the oven during the working process.

[0031] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
