[0017] 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.
[0018] like Figures 1 to 4 As shown, this utility model provides a multi-layer sealed vacuum drying oven, including: a box body 1, a door 2, a base 3, and a sealing plate 6. The box body 1 is generally square in structure and is mounted on the base 3. The interior of the box body 1 is hollow and has a drying chamber 11. The drying chamber 11 has an opening on one side, and the door 2 is hinged to the opening. The opening of the drying chamber 11 has a stepped sealing groove 13, and the sealing plate 6 is filled in the sealing groove 13 and is tightly fitted to the sealing groove 13. The inner side of the door 2 has a sealing plate 24, which abuts against the sealing plate 6, and the edge of the sealing plate 24 is tightly fitted to the sealing groove 13.
[0019] The drying chamber 11 in the housing 1 has a stepped sealing groove 13 at the opening. The sealing groove 13 is filled with a sealing plate 6 to provide the first sealing effect. The door 2 is provided with a sealing plate 24. After the door 2 is closed, the sealing plate 24 abuts against the sealing plate 6, which presses the edge of the front of the sealing plate 6 against the sealing groove 13 to increase the sealing performance. At the same time, the edge of the sealing plate 24 fits tightly with the sealing groove 13 to further increase the sealing effect and provide the second sealing effect.
[0020] The box body 1 has a lock seat 12 on its side, and an electromagnet 15 is installed in the lock seat 12; the box door 2 has a lock block 21 on its side, and a metal block 23 is installed on the lock block 21. The metal block 23 is aligned with the electromagnet 15 and connected by magnetic attraction.
[0021] The lock base 12 is equipped with an electromagnet 15. When the electromagnet 15 is energized, it generates magnetism to attract the metal block 23 on the lock block 21 on the door 2, thereby fixing the door 2 and ensuring the stability of its closed state.
[0022] The sealing groove 13 is a stepped recessed groove, and an annular sealing strip 14 is provided in the sealing groove 13; the sealing strip 14 is made of rubber material and is provided along the edge of the sealing groove 13; the door 2 is provided with a handle 22, which is a C-shaped structure.
[0023] The sealing strip 14 is mainly used to fit tightly against the sealing plate 6 to increase the sealing between the two; the handle 22 is designed to facilitate the opening of the box door 2.
[0024] The drying chamber 11 has a support frame 4 on its inner wall. The support frame 4 is a strip structure and has multiple layers symmetrically arranged on the inner wall of the drying chamber 11. Placement plates 5 are arranged between the support frames 4 on the same layer.
[0025] The support frame 4 is used to support the placement plate 5 for placing items, making full use of the internal space.
[0026] The support frame 4 has a recessed slot 41 at the end away from the door 2. The placement plate 5 has symmetrical support blocks 52 at the bottom. The support blocks 52 have rollers 53 mounted on their sides via a rotating shaft. The rollers 53 are engaged in the slot 41.
[0027] After the placement plate 5 is placed, the roller 53 is locked in the slot 41, which serves as a positioning function and also has a certain locking function to prevent the placement plate 5 from being pulled out at will.
[0028] The placement plate 5 is generally square, and a number of ventilation holes 51 are evenly arranged on the placement plate 5. The ventilation holes 51 are square through holes. A handle groove 54 is provided on the side of the placement plate 5 near the box door 2.
[0029] The ventilation hole 51 facilitates the flow of air on the upper and lower sides of the placement plate 5, and the handle groove 54 makes it easy for the user to grip and tilt the placement plate 5 upwards, thus making it easy to pull out the placement plate 5.
