[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0033] Embodiment 1

[0034] Please refer to Figures 1-5 The present application provides a technical scheme: a ductless electric heating air blowing oven, comprising:

[0035] The oven body 1 is internally provided with a drying cavity 11, and the drying cavity 11 is provided with an opening at one end;

[0036] The air blower 2 is fixedly installed on the oven body 1;

[0037] The movable plate 3 is slidingly connected to the oven body 1;

[0038] The electric push rod 4 has a piston rod fixedly installed on the back of the movable plate 3;

[0039] The oven body 1 is provided with an air outlet 12 at the top, the air blower 2 is used to blow air into the drying cavity 11, the movable plate 3 is provided with a storage groove 31 arranged along the circumferential direction of the movable plate 3 on the side wall, the air bag 5 is arranged in the storage groove 31, the air bag 5 is connected to the air source through the air pipe 51, and the air bag 5 contacts the inner wall of the drying cavity 11 after being inflated.

[0040] Working principle: When the electric heat air oven is used, heating wires can be arranged in front of the air blower 2, and the airflow generated by the air blower 2 is heated by the heating wires and then directly blown to the products to be dried in the drying cavity 11, realizing the windless design of the electric heat air oven and improving the product drying efficiency. The products to be dried are put into the oven body 1 from the opening at one end of the drying cavity 11. The electric push rod 4 drives the movable plate 3 to extend into the oven body 1 from the opening at one end of the drying cavity 11, and the moving distance of the movable plate 3 is adjusted, so that the size of the drying space surrounded by the movable plate 3 and the drying cavity 11 is adjusted according to the number of products to be dried, effectively improving the drying efficiency.

[0041] In order to eliminate the gap between the movable plate 3 and the inner wall of the drying cavity 11 and improve the sealing performance of the drying space, after the movable plate 3 is pushed to the set position by the electric push rod 4, the air bag 5 made of rubber in the receiving groove 31 is inflated by air through the air pipe 51, so that the outer side of the air bag 5 contacts the inner wall of the drying cavity 11, realizing sealing. Conversely, when the movable plate 3 needs to be moved, the air bag 5 is deflated by discharging gas through the air pipe 51, and is in a contracted state, avoiding affecting the movement of the movable plate 3.

[0042] Embodiment 2

[0043] The embodiment further improves the above-mentioned embodiments by further improving the technical scheme as follows: the oven body 1 is provided with an observation window 13.

[0044] The transparent tempered glass is arranged at the observation window 13, which is convenient for observing the drying effect of the products in the oven body 1.

[0045] Embodiment 3

[0046] The embodiment further improves the above-mentioned embodiments by further improving the technical scheme as follows: the movable plate 3 is provided with a guide rod 6 on the back, the guide rod 6 is slidably connected to the oven body 1, and the smooth sliding of the movable plate 3 is ensured. The oven body 1 is provided with a supporting seat 14 on the side end face, the supporting seat 14 is rotatably installed on the side end face of the oven body 1, and the supporting seat 14 is provided with a stop block 15 below, and the stop block 15 is fixedly installed on the side end face of the oven body 1 by bolts.

[0047] When the supporting seat 14 is rotated downward to the horizontal position, the stop block 15 supports the supporting seat 14, preventing the supporting seat 14 from continuing to rotate, so that the supporting seat 14 effectively supports the movable plate 3.

[0048] When the dried products need to be taken out, the supporting seat 14 is rotated outward of the oven body 1, and no longer extends into the opening at the end of the drying cavity 11, avoiding affecting the retreat and removal of the movable plate 3 out of the oven body 1.

[0049] Embodiment 4

[0050] The guiding rod 6 is threadedly connected to the back of the movable plate 3, facilitating dismounting and replacing the guiding rod 6.

[0051] Embodiment 5

[0052] The arc-shaped notch of the guiding rod 6 is arranged on the supporting seat 14, and the guiding rod 6 is positioned.

[0053] The above merely describes the preferred embodiments of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent substitutions or changes according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, and all of them should be covered in the protection scope of the present application.
