Technical Field
[0001] This utility model relates to the field of drying ovens, specifically an electric heating constant temperature forced air drying oven. Background Technology
[0002] An electric heating drying oven, also known as a "drying oven," uses electric heating to conduct air circulation drying tests. It is divided into two types: air drying and vacuum drying. Air drying uses a circulating fan to blow out hot air to ensure a balanced temperature inside the oven. Vacuum drying uses a vacuum pump to extract the air from the oven, making the atmospheric pressure inside the oven lower than normal.
[0003] Publication number CN205245707U discloses an electric heating constant temperature forced-air drying oven. By setting up a placement tube with multiple parallel arranged tubes and evenly distributed ventilation holes, and connecting it with a support rod and a fan, the airflow on the sample surface can be more uniform, and all parts of the sample can be dried, resulting in a better drying effect. However, this patent still has the following problems in actual use:
[0004] It can only dry objects of the same size because the distance between the shelves is fixed and not easy to adjust. However, the size of the objects to be dried is different, which limits the drying of objects. Furthermore, if different objects need to be dried, multiple devices of different sizes need to be produced, which increases manufacturing costs and makes it inconvenient to dry objects of different sizes.
[0005] An electrically heated constant temperature forced-air drying oven is proposed to solve the problems mentioned above. Utility Model Content
[0006] The purpose of this invention is to provide an electric heating constant temperature forced air drying oven to solve the problem mentioned in the background art, which currently can only dry objects of the same size. This is because the distance between the shelves is fixed and not easy to adjust, while the size of the objects to be dried is different, which has certain limitations on drying objects. Furthermore, if different objects need to be dried, multiple devices of different sizes need to be produced, which increases manufacturing costs and makes it inconvenient to dry objects of different sizes.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an electric heating constant temperature forced air drying oven, including a drying oven body and a vent hole opened on one side of the drying oven body;
[0008] Also includes:
[0009] The drying oven body is equipped with an adjustment component inside. The adjustment component includes a slot, and slots are opened on both sides of the interior of the drying oven body. A disc is rotatably connected to one side of the interior of the drying oven body, and the disc is located inside the slot on one side. The rotating shaft of the disc and the drying oven body passes through the drying oven body, and a control block is fixedly connected to one end of the shaft.
[0010] Among them, a rotating block is symmetrically rotated on one side of the disc, and a limit rod is symmetrically fixed inside the empty grooves on both sides, and a slider is symmetrically slidable outside the limit rod.
[0011] The slider has a limiting groove inside, and the rotating block is located inside the limiting groove and fits against the slider. The rotating block can rotate and slide inside the limiting groove.
[0012] Preferably, the slider is symmetrically fixed with stops, and the stops are located at both ends of the limiting groove.
[0013] Preferably, a return spring is fixedly connected between the slider and the drying chamber body, and a first shelf is fixedly connected inside the drying chamber body.
[0014] Preferably, the first shelf is located in the middle of the interior of the drying chamber body.
[0015] Preferably, a second shelf is fixedly connected between the sliders on both sides, and the second shelves on both sides are located above and below the first shelf, respectively.
[0016] Preferably, a limiting component is provided on one side of the drying oven body. The limiting component includes a mounting block, which is fixedly connected to the drying oven body. A locking rod is slidably connected inside the mounting block, and multiple locking slots are symmetrically opened inside the control block.
[0017] Preferably, the top of the mounting block is threaded with a bolt, and the slots are distributed in a ring shape.
[0018] Compared with the prior art, the beneficial effects of this utility model are: this electric heating constant temperature forced air drying oven can adjust the distance between the first shelf and the second shelves on both sides, thereby changing the distance between the shelves and making it easier to accommodate objects of different sizes. The specific details are as follows:
[0019] 1. When the position of the first and second shelves needs to be adjusted according to the specifications of the items to be dried, the control block can be rotated, causing the control block to drive the disc to rotate. The disc will then drive the two rotating blocks on one side to move in a circular motion, causing the sliders on both sides to be squeezed and move away from each other. The rotation of the rotating blocks reduces the friction with the sliders, thereby extending their service life. During the movement of the sliders, the return spring is compressed. The function of the compressed return spring is to facilitate the return of the sliders to their original position, thereby making the distance between the first and second shelves adjustable, which is convenient for placing items of different sizes.
[0020] 2. After adjustment, slide the lever down and it will lock into the slot, thus restricting the position of the control block and ensuring the stability of the second shelf position after adjustment. Finally, tighten the bolt to secure the lever. Attached Figure Description

Detailed Implementation
[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figures 1-7 The present invention provides the following technical solution:
[0031] An electric heating constant temperature forced air drying oven is disclosed. Since electric heating constant temperature forced air drying ovens are existing technology, the specific drying process and method will not be elaborated upon here. The oven includes a drying oven body 1 and a vent 2 opened on one side of the drying oven body 1. An adjustment component 3 is provided inside the drying oven body 1. The adjustment component 3 includes a slot 301, and slots 301 are opened on both sides of the interior of the drying oven body 1. A disc 302 is rotatably connected to one side of the interior of the drying oven body 1, and the disc 302 is located inside one of the slots 301. The rotating shaft of the disc 302 and the drying oven body 1 passes through the drying oven body 1, and a control block 303 is fixedly connected to one end of the shaft. A rotating block 304 is symmetrically rotated on one side of the disc 302, and limit rods 305 are symmetrically fixed inside the slots 301 on both sides. Figure 2-5 As shown, the rotatable control block 303 causes the disk 302 to rotate, and then the disk 302 causes two rotating blocks 304 on one side to move in a circular motion. Then the rotating blocks 304 on both sides slide inside the limiting groove 307, and the distance of the rotating blocks 304 changes as they run.
[0032] This causes the rotating block 304 to squeeze the slider 306, and the sliders 306 on both sides will move away from each other due to the squeezing. The function of the rotating block 304 is to reduce the friction with the slider 306, thereby extending the service life. The slider 306 slides symmetrically on the outside of the limiting rod 305.
[0033] The slider 306 has a limiting groove 307 inside, and the rotating block 304 is located inside the limiting groove 307 and fits against the slider 306. The rotating block 304 can rotate and slide inside the limiting groove 307.
[0034] A stop block 308 is symmetrically fixed on the slider 306, and the stop block 308 is located at both ends of the limiting groove 307. A return spring 309 is fixedly connected between the slider 306 and the drying oven body 1. A first shelf 310 is fixedly connected inside the drying oven body 1. The first shelf 310 is located in the middle of the interior of the drying oven body 1. A second shelf 311 is fixedly connected between the sliders 306 on both sides. Figure 2 , Figures 4-5 As shown, the return spring 309 is compressed during the movement of the slider 306. Furthermore, the spring 309 can be a high-temperature resistant spring, such as a high-temperature alloy spring or a ceramic spring, so as to avoid the high temperature inside the drying oven body 1 causing the spring 309 to fail. Moreover, alloy springs and ceramic springs are existing technologies.
[0035] The function of the compressed return spring 309 is to facilitate the reset of the slider 306, and in conjunction with the stop block 308, to prevent the rotating block 304 from disengaging from the slider 306. Then, as the sliders 306 on both sides move, they will drive the second shelves 311 on both sides to move away from each other, thereby making the distance between the first shelf 310 and the second shelf 311 adjustable, so as to facilitate the placement of objects of different sizes. The second shelves 311 on both sides are located above and below the first shelf 310, respectively.
[0036] A limiting component 4 is provided on one side of the drying oven body 1. The limiting component 4 includes a mounting block 401, which is fixedly connected to the drying oven body 1. A locking rod 402 is slidably connected inside the mounting block 401, and multiple locking slots 403 are symmetrically opened inside the control block 303. A bolt 404 is threadedly connected to the top of the mounting block 401. Figure 6 , 7 As shown, after adjustment, the lever 402 can be slid down, and then the lever 402 will be locked into the inside of the slot 403, thereby restricting the position of the control block 303, so as to ensure the stability of the position of the second shelf 311 after adjustment. Finally, the bolt 404 is tightened to hold the lever 402 in place, and the slot 403 is distributed in a ring.
[0037] Working principle: Before using this type of electric thermostatic drying oven, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 7As shown, firstly, when the positions of the first shelf 310 and the second shelf 311 need to be adjusted according to the specifications of the items to be dried, the control block 303 can be rotated, causing the control block 303 to drive the disc 302 to rotate. Then, the disc 302 will drive the two rotating blocks 304 on one side to move in a circular motion. Then, the rotating blocks 304 on both sides will slide inside the limiting groove 307. As the distance of the rotating blocks 304 changes during operation, the rotating blocks 304 will press the sliders 306. Then, the sliders 306 on both sides will be pushed away from each other due to the pressure. The rotation reduces friction with the slider 306, thus extending its service life. During the movement of the slider 306, the return spring 309 is compressed. The compression of the return spring 309 facilitates the reset of the slider 306 and, in conjunction with the stop block 308, prevents the rotating block 304 from disengaging from the slider 306. As the sliders 306 on both sides move, they also cause the second shelves 311 on both sides to move away from each other, thereby making the distance between the first shelf 310 and the second shelf 311 adjustable, which facilitates the placement of objects of different sizes.
[0038] After adjustment, slide the lever 402 downwards. The lever 402 will then engage with the slot 403, thereby restricting the position of the control block 303. This helps to ensure the stability of the position of the second shelf 311 after adjustment. Finally, tighten the bolt 404 to secure the lever 402.
[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
