Description

Technical Field

[0001] This application relates to the field of vertical forced-air drying oven technology, and more particularly to a vertical forced-air drying oven. Background Technology

[0002] Vertical forced-air drying ovens are drying equipment suitable for various products or materials, as well as electrical, instrument, meter, component, electronic, electrical, automotive, aerospace, communications, plastics, machinery, chemical, food, chemical products, and hardware tools, to perform drying and various temperature adaptability tests under constant temperature conditions. Existing vertical forced-air drying ovens typically include a chamber and a movable door. The interior of the chamber has a drying cavity, and within the drying cavity, several support plates are arranged vertically to support the components.

[0003] In existing vertical forced-air drying ovens, the support plate covers the entire horizontal area of ​​the drying cavity. However, laboratory containers and utensils vary in height and size. When some of the items being dried are taller, the only way to create enough space is to remove and change the height of the upper support plate. This results in significant waste of drying space at the same height as the item, leading to low drying efficiency. Therefore, an improvement to the vertical forced-air drying oven is proposed.

[0022] In this invention, a rotating drive wheel drives a lead screw to rotate. Through the cooperation between the lead screw and the movable support frame, the lead screw drives the movable support frame to slide up and down along a guide rod to adjust its position, thereby adjusting the internal spatial distribution of the drying chamber. Utilizing the cooperation between the support frame, the movable groove, the support plate, the receiving cavity, and the snap-fit ​​unit, the support plate is slidably snapped into the inside of the support frame.

[0033] like Figure 1 - Figure 6As shown, this embodiment provides a vertical forced-air drying oven, including a box body 1 and a box door 2. The box body 1 has an internal drying cavity 101. A fixed support frame 3 is fixedly installed on the inner wall of the drying cavity 101. Two sliding grooves 5 are symmetrically opened on both sides of the inner wall of the drying cavity 101 above the fixed support frame 3. A lead screw 7 is rotatably connected to the interior of each sliding groove 5, and a guide rod 9 is fixedly connected to it. A drive groove 6 is opened below one of the sliding grooves 5. A drive wheel 8 is fixedly connected to the lower end of the lead screw 7 inside the drive groove 6. A movable support frame 4 is threaded onto the outer surface of the lead screw 7. A support frame 11 is placed on the top of both the fixed support frame 3 and the movable support frame 4. Two movable grooves 13 are symmetrically opened on both sides of the inner wall of the support frame 11. A support plate 14 is arranged between the two movable grooves 13. A receiving cavity 15 is symmetrically opened inside the support plate 14. A snap-fit ​​unit 17 is fixedly connected inside the receiving cavity 15. The carrier plate 14 is slidably connected to the support plate 14 via the snap-fit ​​unit 17. In use, the screw 7 is driven to rotate by the rotating drive wheel 8. Through the cooperation between the screw 7 and the movable support frame 4, the screw 7 can drive the movable support frame 4 to slide up and down along the guide rod 9 to adjust its position, thereby adjusting the internal space distribution of the drying cavity 101. By utilizing the cooperation between the support frame 11, the movable groove 13, the support plate 14, the receiving cavity 15 and the snap-fit ​​unit 17, the support plate 14 is slidably snapped into the inside of the support frame 11, so that the installation and removal of each support plate 14 is independent. That is, in use, the position of the movable support frame 4 and the number of support plates 14 can be adjusted to make room in the drying cavity 101 for each device to perform drying work, making full use of the drying space in the drying cavity 101 and helping to improve drying efficiency.

[0034] In this embodiment, as Figure 5 and 6 As shown, the snap-fit ​​unit 17 includes a snap-fit ​​block 1701 that slides inside the receiving cavity 15. A spring 1702 is fixedly connected to the rear end of the snap-fit ​​block 1701, and the other end of the spring 1702 is fixedly connected to the inner wall of the receiving cavity 15. The front end of the snap-fit ​​block 1701 penetrates the support plate 14 and is inserted into the moving slot 13 under the elastic force of the spring 1702. An adjusting block 1703 is fixedly connected to the upper end of the snap-fit ​​block 1701. In use, by pulling the adjusting block 1703, the snap-fit ​​block 1701 is completely retracted into the receiving cavity 15, so that the support plate 14 can be placed inside the support frame 11. At this time, the adjusting block 1703 is released, and the front end of the snap-fit ​​block 1701 is inserted into the moving slot 13 under the elastic force of the spring 1702, so that the support plate 14 can be installed inside the support frame 11, realizing the quick installation and removal of the support plate 14.

[0035] In this embodiment, as Figure 5 and 6 As shown, an adjustment groove 16 is provided through the upper surface of the support plate 14 above the receiving cavity 15. The adjustment block 1703 slides inside the adjustment groove 16. In use, the adjustment groove 16 is used to limit the movement trajectory of the adjustment block 1703 to ensure the accuracy and stability of the adjustment block 1703 when it moves.

[0036] In this embodiment, as Figure 6 As shown, the upper surface of the support plate 14 is provided with several vent holes 18. During use, the vent holes 18 allow the drying gas to flow freely within the drying cavity 101.

[0037] In this embodiment, as Figure 3 , 4 As shown in Figure 5, both the fixed support frame 3 and the movable support frame 4 have grooves 10 on their tops, and the bottom of the support frame 11 is fixedly connected to a protrusion 12. The protrusion 12 is adapted to the groove 10. In use, the support frame 11 is precisely placed on the top of the fixed support frame 3 and the movable support frame 4 through the cooperation between the protrusion 12 and the groove 10.

[0038] In this embodiment, as Figure 2 As shown, a sealing strip 21 is fixedly connected to the housing 1. The sealing strip 21 is distributed around the edge of the drying inner cavity 101. During use, the sealing strip 21 is used to increase the sealing performance of the device and prevent heat from escaping.

[0039] In this embodiment, as Figure 1 As shown, the outer walls of both the housing 1 and the door 2 are coated with an anti-static coating. A handle 19 is fixedly connected to the front side of the door 2. The outer surface of the handle 19 is covered with an insulating sleeve. In use, the safety of the device is ensured by eliminating the potential for static electricity.

[0040] In this embodiment, as Figure 1 As shown, an observation window 20 is provided through the front side of the door 2. The inside of the observation window 20 is equipped with transparent glass. During use, the working conditions inside the drying chamber 101 can be observed through the observation window 20 and the transparent glass.

[0041] The working principle of this utility model is as follows: When using the vertical blower drying oven of this application, the drive wheel 8 drives the lead screw 7 to rotate, and the rotation of the lead screw 7 drives the movable support frame 4 to slide up and down along the guide rod 9 to adjust its position, thereby adjusting the internal space distribution of the drying cavity 101. By pulling the adjustment block 1703, the locking block 1701 is completely retracted into the receiving cavity 15, which facilitates the subsequent placement of the support plate 14 inside the support frame 11. After placement, the adjustment block 1703 is released, and the front end of the locking block 1701 is inserted into the movable slot 13 under the elastic force of the spring 1702, so that the support plate 14 can be installed inside the support frame 11, realizing the quick installation and removal of the support plate 14. In other words, when using this device, the position of the movable support frame 4 and the number of support plates 14 can be adjusted to make room in the drying cavity 101 for each device to perform drying work, making full use of the drying space in the drying cavity 101 and helping to improve drying efficiency.
