Description

Technical Field

[0001] This utility model relates to the field of drying device technology, specifically a portable endoscope local constant temperature drying box. Background Technology

[0002] An endoscope is an important medical device that allows doctors to observe the inside of the human body without performing open surgery. Endoscopes typically consist of a flexible or rigid tube with a small camera and light source at one end, transmitting images to an external monitor so doctors can clearly see the internal structure.

[0003] Endoscopes typically require maintenance after prolonged use. Current maintenance methods generally involve applying epoxy resin adhesive to the bent outer skin of the endoscope and allowing it to cure completely. After application, curing takes 2-6 hours at room temperature before the next installation step can proceed. This traditional method has the following problems: 1. The long curing time reduces work efficiency; 2. The slow curing process and the fluidity of the adhesive cause it to flow downwards during prolonged standing, affecting its setting and bonding; 3. It fails to create dual drying channels (horizontal and vertical). Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a portable endoscope local constant temperature drying oven, which solves the problems of long glue curing time affecting work efficiency, slow glue curing process, glue with a certain fluidity, glue flowing downwards after long-term standing, affecting the shape and bonding effect of the glue after curing, and the inability to form a dual drying of horizontal and vertical air channels. By setting a second air channel and opening a second air supply channel, a vertical air channel is formed. By using the first and second air channels together, a horizontal air channel is formed with the center of the drying oven as the reference, the second vertical air channel is set inside, and the first air channel is set around the outside. The vertical air channel can ensure that the material in the central area is heated evenly, while the horizontal air channel can ensure that the material in the edge area can also fully contact the hot air.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a portable endoscope local constant temperature drying chamber, comprising a chamber assembly, a ventilation assembly, and a heating assembly. The chamber assembly includes a drying chamber and a door. The ventilation assembly includes a first hot air blower, a first exhaust fan, a second hot air blower, and a second exhaust fan. The heating assembly includes a mounting bracket, a first heating tube, and a second heating tube. An insulating inner layer is attached to the inner wall of the drying chamber. A drying platform is installed on the inner wall of the bottom surface of the drying chamber. Ventilation holes are evenly spaced on the inner wall of the drying platform. A first mounting groove is formed in the wall of the drying chamber. Second mounting grooves are symmetrically formed on the top and bottom walls of the drying chamber. The air supply end of the first hot air blower passes through the first mounting groove and extends to connect with a first air duct. A first air supply slot is formed on the inner wall of the first air duct. Second air ducts are symmetrically connected to the inner wall of the drying chamber. The first heating tube and the second heating tube are both installed inside the drying chamber via the mounting bracket.

[0006] The beneficial effects of this utility model are as follows: When the second heating tube is started, the heat generated by the second heating tube raises the temperature of the surrounding air, forming hot air. At the same time, the second hot air blower drives the hot air to flow in the second air duct and the inner chamber of the drying chamber, heating and curing the endoscope coated with epoxy resin, thereby accelerating the curing process of the epoxy resin and avoiding uneven thickness of the cured epoxy resin due to flow during the curing process. Through the setting of the second air duct and the opening of the second air delivery slot, a vertical air duct is formed. Through the joint use of the first air duct and the second air duct, a horizontal air duct is formed with the center of the drying chamber as the reference, the second vertical air duct is set inside, and the first air duct is set around the outside. The vertical air duct can ensure that the material in the central area is heated evenly, while the horizontal air duct can ensure that the material in the edge part can also fully contact the hot air.

[0007] To facilitate observation of the drying oven through the observation window:

[0008] As a further improvement to the above technical solution: the door is rotatably connected to the drying oven via a hinge, a sealing gasket is provided at the connection between the door and the drying oven, and an observation window is installed on the inner side of the door.

[0009] The beneficial effects of this improvement are: when in use, the chamber door is opened and the endoscope is placed on the drying platform, and then the endoscope is dried. The observation window makes it easy to observe the drying chamber.

[0010] For the installation of the second hot air blower and the second exhaust blower:

[0011] As a further improvement to the above technical solution: there are two first mounting slots, which are symmetrically opened on both sides of the drying box. The first mounting slot and the second mounting slot both penetrate the insulating inner layer connected to the drying box. The outer wall of the first air duct penetrates the insulating inner layer and extends to connect with the inner wall of the drying box.

[0012] The beneficial effects of this improvement are as follows: the first mounting slot is used for the installation of the first hot air blower and the first exhaust fan, and the second mounting slot is used for the installation of the second hot air blower and the second exhaust fan.

[0013] To extract humid gas from inside the drying chamber:

[0014] As a further improvement to the above technical solution: the first exhaust fan is installed on the outer wall of the drying box away from the first hot air fan and is electrically connected to the operation panel. The air inlet of the first exhaust fan passes through the first mounting groove and extends to be connected to the first air duct.

[0015] The beneficial effects of this improvement are as follows: When the first exhaust fan is started, under the action of centrifugal force, air is thrown from the center of the first exhaust fan impeller to the edge of the impeller, creating a low-pressure zone in the center of the impeller. Because of the low pressure in the center of the impeller, the surrounding air will be continuously drawn into the center of the impeller under the action of atmospheric pressure. The drawn-in air gains energy under the action of the impeller and is discharged from the edge of the impeller at a higher speed and pressure, enters the first exhaust fan and is discharged through its air outlet, thus realizing the extraction of humid gas in the drying box.

[0016] In order to form a horizontal air duct by setting up the first air duct and opening the first air supply slot:

[0017] As a further improvement to the above technical solution: the fixing frame has two sets and is connected to the inner wall of the drying oven by bolts, and the first heating tube is electrically connected to the operation panel.

[0018] The beneficial effects of this improvement are as follows: When the first heating tube is started, the heat generated by the first heating tube raises the temperature of the surrounding air, forming hot air. At the same time, the first hot air blower drives the hot air to flow in the drying chamber. The hot air comes into full contact with the endoscope, heating and curing the endoscope coated with epoxy resin, thereby accelerating the curing process of the epoxy resin and avoiding uneven thickness of the cured epoxy resin due to flow during the curing process. A horizontal air duct is formed by setting up the first air duct and opening the first air delivery slot.

[0019] In order to enter the second exhaust fan and be exhausted through its outlet:

[0020] As a further improvement to the above technical solution: the second exhaust fan is installed on the top of the drying chamber and electrically connected to the operation panel. The air inlet of the second exhaust fan passes through the second mounting groove and extends to communicate with the second air supply groove. The second air supply groove has a first air supply groove evenly spaced on the side wall away from the second exhaust fan.

[0021] The beneficial effects of this improvement are as follows: When the second exhaust fan is started, under the action of centrifugal force, air will be thrown from the center of the impeller to the edge of the impeller, creating a low-pressure zone in the center of the impeller. Due to the low pressure in the center of the impeller, the surrounding air will be continuously drawn into the center of the impeller under the action of atmospheric pressure. The drawn-in air gains energy under the action of the impeller and is discharged from the edge of the impeller at a higher speed and pressure, enters the second exhaust fan and is discharged through its outlet, thus achieving the extraction of humid gas in the drying box.

[0022] The heated air is then blown out through the air outlet by the fan.

[0023] As a further improvement to the above technical solution: the second hot air blower is installed at the bottom of the drying chamber and electrically connected to the operation panel. The air supply end of the second hot air blower passes through the second mounting groove and extends to be connected to the second air duct. The second air duct has a second air supply slot at equal intervals on the side wall away from the second hot air blower. The first hot air blower and the second hot air blower include an air inlet and an axial flow fan.

[0024] The beneficial effects of this improvement are as follows: After the second hot air blower is started, the second hot air blower causes the air to flow along the direction of the blower shaft through the rotation of the impeller, thereby realizing the intake and pushing of air. After the intake air enters the hot air blower, it will flow through the heating element. The heated air will then be blown out through the air outlet under the action of the blower.

[0025] To ensure uniform heating of materials in the central area, vertical air ducts allow materials at the edges to also have sufficient contact with hot air.

[0026] As a further improvement to the above technical solution: the second heating tube is connected to the bottom wall of the drying oven via a fixing bracket, the second heating tube is located directly above the second air duct, and the second heating tube is electrically connected to the operation panel.

[0027] The beneficial effects of this improvement are as follows: When the second heating element is activated, the heat generated by the second heating element raises the temperature of the surrounding air, forming hot air. At the same time, the second hot air blower drives the hot air to flow in the second air duct and the inner chamber of the drying chamber, heating and curing the endoscope coated with epoxy resin. This accelerates the curing process of the epoxy resin and avoids uneven thickness of the cured epoxy resin due to flow during the curing process. By setting up the second air duct and opening the second air delivery slot, a vertical air duct is formed. Through the combined use of the first and second air ducts, a horizontal air duct is formed with the center of the drying chamber as the reference, with the second vertical air duct set inside and the first air duct set around it. The vertical air duct can ensure uniform heating of the material in the central area, while the horizontal air duct can ensure that the material in the edge area can also fully contact the hot air.

The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0035] like Figure 1-5As shown, a portable endoscope local constant temperature drying chamber includes a chamber assembly 1, a ventilation assembly 2, and a heating assembly 3. The chamber assembly 1 includes a drying chamber 11 and a door 17. The ventilation assembly 2 includes a first hot air blower 21, a first exhaust fan 24, a second hot air blower 25, and a second exhaust fan 28. The heating assembly 3 includes a mounting bracket 31, a first heating tube 32, and a second heating tube 33. An insulating inner layer 16 is attached to the inner wall of the drying chamber 11. A drying platform 12 is installed on the inner wall of the bottom surface of the drying chamber 11. Ventilation holes 13 are evenly spaced on the inner wall of the drying platform 12. A first mounting groove 14 is formed in the wall of the drying chamber 11. The top and bottom walls of the drying chamber 11 are symmetrically... A second mounting slot 15 is provided. The air supply end of the first hot air blower 21 passes through the first mounting slot 14 and extends to connect with the first air duct 22. A first air supply groove 23 is opened on the inner wall of the first air duct 22. The inner wall of the drying chamber 11 is symmetrically connected with second air ducts 26. The first heating tube 32 and the second heating tube 33 are both installed inside the drying chamber 11 by a fixing bracket 31. The chamber door 17 is rotatably connected to the drying chamber 11 by a hinge. A sealing gasket is provided at the connection between the chamber door 17 and the drying chamber 11. An observation window 18 is installed on the inner side of the chamber door 17. In use, the chamber door 17 is opened and the endoscope is placed on the drying platform 12. Then, the endoscope is dried. The observation window 18 facilitates the drying process. Upon observation of the drying chamber 11, two first mounting slots 14 are symmetrically located on both sides of the drying chamber 11. Both the first mounting slot 14 and the second mounting slot 15 penetrate the insulating inner layer 16 connected to the drying chamber 11. The outer wall of the first air duct 22 penetrates the insulating inner layer 16 and extends to connect with the inner wall of the drying chamber 11. The first mounting slot 14 is used for installing the first hot air blower 21 and the first exhaust fan 24. The second mounting slot 15 is used for installing the second hot air blower 25 and the second exhaust fan 28. The first exhaust fan 24 is installed on the outer wall of the drying chamber 11 on the side away from the first hot air blower 21 and is electrically connected to the control panel. The air inlet of the first exhaust fan 24 penetrates... The first mounting groove 14 is inserted and extended to connect with the first air duct 22; the first exhaust fan 24 is started and started. Under the action of centrifugal force, air is thrown from the center of the impeller of the first exhaust fan 24 to the edge of the impeller, so that a low-pressure area is formed in the center of the impeller. Because a low pressure is formed in the center of the impeller, the surrounding air will be continuously drawn into the center of the impeller under the action of atmospheric pressure. The drawn-in air gains energy under the action of the impeller and is discharged from the edge of the impeller at a high speed and pressure, enters the first exhaust fan 24 and is discharged through its air outlet, thereby realizing the extraction of humid gas in the drying box 11. There are two sets of the fixed frame 31 and they are connected to the inner wall of the drying box 11 by bolts. The first heating tube 32 is electrically connected to the operation panel.The first heating element 32 is activated, and the heat generated by it raises the temperature of the surrounding air, creating hot air. Simultaneously, the first hot air blower 21 drives the hot air to circulate within the drying chamber 11. The hot air makes full contact with the endoscope, heating and curing the epoxy resin-coated endoscope. This accelerates the curing process of the epoxy resin and prevents uneven thickness of the cured resin due to flow during curing. A horizontal airflow is formed through the first air duct 22 and the first air delivery slot 23. The second exhaust fan 28 is installed within the drying chamber. The top of the second exhaust fan 28 is electrically connected to the control panel. The air inlet of the second exhaust fan 28 passes through the second mounting groove 15 and extends to communicate with the second air supply groove 27. The second air supply groove 27 has first air supply grooves 23 evenly spaced on the side wall away from the second exhaust fan 28. When the second exhaust fan 28 is started, under the action of centrifugal force, air is thrown from the center of the impeller of the second exhaust fan 28 to the edge of the impeller, so that a low-pressure area is formed in the center area of ​​the impeller. Because a low pressure is formed in the center of the impeller, the surrounding air will be continuously drawn into the center of the impeller under the action of atmospheric pressure. The incoming air gains energy under the action of the impeller and is discharged from the edge of the impeller at a high speed and pressure. It then enters the second exhaust fan 28 and is discharged through its outlet, thus extracting the humid gas inside the drying chamber 11. The second hot air fan 25 is installed at the bottom of the drying chamber 11 and is electrically connected to the control panel. The air supply end of the second hot air fan 25 passes through the second mounting groove 15 and extends to connect with the second air duct 26. The second air duct 26 has second air supply slots 27 evenly spaced on the side wall away from the second hot air fan 25. The first hot air fan 21 and the second hot air fan... 25 includes an air inlet and an axial flow fan; after the second hot air fan 25 is started, the second hot air fan 25 causes air to flow along the direction of the fan shaft through the rotation of the impeller, realizing the intake and pushing of air. After the intake air enters the hot air fan, it will flow through the heating element. The heated air is blown out through the air outlet under the action of the fan. The second heating tube 33 is connected to the bottom wall of the drying box 11 through the fixing bracket 31. The second heating tube 33 is located directly above the second air duct 26. The second heating tube 33 is electrically connected to the operation panel.The second heating element 33 is activated, generating heat that raises the temperature of the surrounding air, creating hot air. Simultaneously, the second hot air blower 25 drives this hot air to circulate within the second air duct 26 and the inner chamber of the drying chamber 11, heating and curing the epoxy resin-coated endoscope. This accelerates the curing process and prevents uneven epoxy resin thickness caused by flow during curing. The second air duct 26 and the second air delivery slot 27 create a vertical air duct. The combined use of the first air duct 22 and the second air duct 26 forms a horizontal air duct system with the drying chamber 11 as the center, containing the vertical second air duct 26 and surrounding the horizontal first air duct 22. The vertical air duct ensures uniform heating of the material in the central area, while the horizontal air duct allows the material at the edges to also fully contact the hot air.

[0036] The working principle of this utility model is as follows: In use, the door 17 is opened and the endoscope is placed on the drying platform 12. The endoscope is then dried. The observation window 18 facilitates observation of the drying chamber 11. The first heating tube 32 is activated, and the heat generated by the first heating tube 32 raises the temperature of the surrounding air, forming hot air. Simultaneously, the first hot air blower 21 drives the hot air to flow within the drying chamber 11. Through the arrangement of the first air duct 22 and the opening of the first air delivery slot 23, a horizontal air duct is formed. The first exhaust fan 24 is activated, and under the action of centrifugal force, air is thrown from the center of the impeller of the first exhaust fan 24 to the edge of the impeller, entering the first exhaust fan. The blower 24 exhausts the humid air from the drying chamber 11 through its outlet. The second heating element 33 is activated, generating heat that raises the ambient air temperature, creating hot air. Simultaneously, the second hot air blower 25 drives this hot air to circulate within the second air duct 26 and the inner chamber of the drying chamber 11, heating and curing the epoxy resin-coated endoscope. This accelerates the curing process and prevents uneven epoxy resin thickness caused by flow during curing. After the second hot air blower 25 is activated, its impeller rotation causes air to flow along the blower shaft, thus drawing in air. The air drawn in is pushed into the hot air blower and flows through the heating element. The heated air, under the action of the blower, is blown out through the outlet. This activates the second exhaust fan 28. Under centrifugal force, the air is thrown from the center of the impeller of the second exhaust fan 28 to the edge, creating a low-pressure zone in the center. Because of this low pressure, surrounding air is continuously drawn into the impeller center under atmospheric pressure. The drawn-in air gains energy under the action of the impeller and is discharged at a higher speed and pressure from the impeller edge, entering the second exhaust fan 28 and being discharged through its outlet, thus achieving the removal of humid air from the drying chamber 11. The material is extracted by setting up the second air duct 26 and opening the second air supply slot 27 to form a vertical air duct. By using the first air duct 22 and the second air duct 26 together, a horizontal air duct is formed with the center of the drying box 11 as the reference, with the second air duct 26 vertical air duct set inside and the first air duct 22 set around it on the outside. The vertical air duct can ensure that the material in the central area is heated evenly, while the horizontal air duct can ensure that the material in the edge part can also fully contact the hot air. The first mounting slot 14 is used to install the first hot air fan 21 and the first exhaust fan 24. The second mounting slot 15 is used to install the second hot air fan 25 and the second exhaust fan 28.
