[0019] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0020] Example 1: A drying device for cleaning endoscope optical lenses, such as... Figures 1-5As shown, it includes a furnace body 1, a control console 2, a vacuum pump 21, a pressure extraction pipe 22, a furnace door 3, a heat insulation plate 4, a hollow cylinder 5, a drying lamp 52, a hanging plate 53, a lens fixture 6, a pad block 61, and a clamping block 62; the control console 2 is located on the left side of the furnace body 1. Through the control console 2, various parameters in the entire drying process can be adjusted and monitored to ensure that the drying conditions meet the requirements. The upper right part of the furnace body 1 is provided with a processing cavity, which is the main working area for lens drying. The front of the furnace body 1 is provided with a sliding furnace door 3, through which the lens fixture 6 can be easily placed into or taken out of the processing cavity. At the same time, during the drying process, the furnace door 3 seals the processing cavity to ensure the effective formation of a vacuum environment. The lower part of the furnace body 1 has an equipment slot, in which a vacuum pump 21 is installed. The input end of the vacuum pump 21 is connected to the inside of the processing cavity through a pressure extraction pipe 22. By starting the vacuum pump 21, the air in the processing cavity can be effectively extracted to form a vacuum environment, thereby lowering the boiling point of water and accelerating the evaporation process of water. The front side of the processing cavity is provided with a heat insulation plate 4, and a hollow cylinder 5 is rotatably provided on the heat insulation plate 4. The design of the hollow cylinder 5 makes full use of the internal space, and the hollow cylinder 5 can rotate to ensure that the lens inside can be heated evenly. A drying lamp 52 is installed on the hollow cylinder 5. The drying lamp 52 is located at the center of the hollow cylinder 5. The irradiation of the drying lamp 52 provides the necessary heat to accelerate the evaporation of moisture on the lens surface. Multiple hanging plates 53 are spaced apart inside the hollow cylinder 5. A lens fixture 6 is slidably installed on the hanging plates 53. The lens fixture 6 consists of a connecting frame and a placement plate. The placement plate is arc-shaped and has several locking holes spaced apart. The locking holes are used to lock one end of the lens. A pad 61 is provided along the edge of the hole on one side of the locking hole. Two clamping blocks 62 are provided on the other side of the locking hole. The two clamping blocks 62 are symmetrically arranged to hold the other end of the lens. This design ensures that the lens is firmly fixed during the drying process and avoids displacement caused by vibration or other reasons.

[0021] By placing lenses in batches into the drying equipment using lens fixture 6, the vacuum environment inside the equipment lowers the boiling point of water, and combined with the drying lamp 52, accelerates the evaporation of moisture on the lenses. Compared with temperature-sensitive endoscope lenses, this reduces the impact of heat on the lenses, allowing for the processing of a large number of lenses at once, significantly improving drying efficiency and throughput. Specifically, after setting the drying conditions via control panel 2, the furnace door 3 is opened, and the lens fixture 6 containing the lenses is placed into the hollow cylinder 5. The furnace door 3 is then closed, and the vacuum pump 21 is started to create a vacuum environment in the processing cavity. Before this, the drying lamp 52 is turned on to bring the temperature inside the processing cavity to the required temperature. The lenses are rapidly dried under the action of vacuum and heat flow, ultimately achieving a highly efficient, safe, and uniform drying effect.

[0022] Example 2: Based on Example 1, Example 2 is as follows: Figures 2-3As shown, it also includes a second drying lamp 7, which is provided on the cavity wall of the processing cavity and arranged around the hollow cylinder 5; in addition, it also includes a gear ring 8 and a transmission component 81. The gear ring 8 is provided on the outside of the hollow cylinder 5, and the transmission component 81 is provided in the processing cavity of the furnace body 1. The transmission component 81 consists of a transmission motor and a gear. The gear of the transmission component 81 meshes with the gear ring 8, and the gear ring 8 is driven to rotate through the transmission component 81, which synchronously drives the hollow cylinder 5 to rotate, so that the hollow cylinder 5 rotates in the processing cavity.

[0023] In general, by arranging multiple drying lamps 7 around the outside of the hollow cylinder 5, and cooperating with the transmission component 81 and the gear ring 8 to drive the hollow cylinder 5 to rotate, the lens being dried can be made to contact the heat flow inside the furnace more evenly. Specifically, after the equipment is started, the operator sets the drying conditions through the control panel 2, opens the furnace door 3, puts the lens fixture 6 containing the lens into the hollow cylinder 5, and then closes the furnace door 3. Subsequently, the vacuum pump 21 is started to create a vacuum environment in the processing cavity, lowering the boiling point of water. At the same time, the drying lamps 52 and 7 are turned on simultaneously. The drying lamp 52 is located in the center inside the hollow cylinder 5, providing an internal heat source, while the drying lamps 7 are evenly distributed on the cavity wall of the processing cavity, heating the hollow cylinder 5 from the outside to ensure even heat distribution. After the drive motor of the transmission component 81 is started, it drives the hollow cylinder 5 to rotate through the meshing of the gear and the gear ring 8, so that the lens inside the hollow cylinder 5 can be evenly contacted by the heat flow provided from both the inside and outside during the rotation, thereby achieving a highly efficient drying effect.

[0024] This design not only ensures that each lens receives uniform heat distribution, avoiding localized overheating or uneven drying, but also greatly improves drying efficiency and product quality. Due to the rotation of the hollow cylinder 5 and the multi-angle heat flow supply, the moisture on the lens surface can evaporate rapidly, shortening the drying time and improving production efficiency. At the same time, the formation of a vacuum environment also reduces the impact of heat on temperature-sensitive endoscope lenses, ensuring the quality and performance of the lenses. In this way, not only is drying efficiency improved, but the safety and reliability of the drying process are also guaranteed, making it suitable for large-scale production and high-quality applications.

[0025] In addition, such as Figure 2 and Figure 5As shown, the furnace also includes a heat recovery unit 9, a heating chamber 92, and a heat transfer plate 93. The heat recovery unit 9 is installed in the equipment slot of the furnace body 1. The heat recovery unit 9 contains a heat separation component. The heating chamber 92 is located at the rear of the processing cavity and is tightly connected to the heat recovery unit 9 through a pipe. A heat transfer plate 93 is installed on the side of the heating chamber 92 facing the hollow cylinder 5. The heat recovery unit 9 is connected to the output end of the vacuum pump 21. The mixed hot airflow discharged by the vacuum pump 21 during the vacuuming process is sent into the heat recovery unit 9. The heat separation component in the heat recovery unit 9 separates the heat in the mixed hot airflow and transfers this heat to the heating chamber 92 through a pipe. The heat in the heating chamber 92 is efficiently transferred to the processing cavity through the heat transfer plate 93, further increasing the temperature in the processing cavity and accelerating the evaporation of moisture on the lens surface. Through the cooperation of the heat recovery unit 9 and the heating chamber 92, not only is energy saved and the thermal energy utilization rate improved, but the heating time is also reduced, further improving the overall drying efficiency and economy.

[0026] Finally, as Figure 1 As shown, it also includes a partition 10. The partition 10 is installed at the opening of the equipment slot of the furnace body 1. The partition 10 is detachable. The design of the partition 10 not only effectively seals the opening of the equipment slot, preventing external impurities from entering the equipment, ensuring the stability and cleanliness of the operation of related components on the equipment, but also facilitates maintenance and repair.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
