DETAILED DESCRIPTION

[0026] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0027] To make the purpose, technical scheme and advantages of the utility model more clear, the embodiments of the utility model will be further described in detail below with reference to the drawings.

[0028] Please refer to Figures 1-6 The utility model discloses a sealing device of hot air circulation oven, which comprises:

[0029] The sealing assembly comprises the box door 11, the clamping groove 12 and the sealing ring 13.

[0030] The sealing assembly further comprises the box body 10, and the box door 11 is hinged to the side edge of the box body 10 and is fixed by mechanical locking.

[0031] The box body 10 is internally used for placing articles to be dried, the box door 11 is used for sealing the box body 10, the clamping groove 12 is used for connecting the sealing ring 13, and the sealing ring 13 plays a sealing role.

[0032] The convenient dismounting assembly comprises the first recess 20, the plug block 21, the rotating shaft 24, the torsional spring 25, the baffle 26 and the third recess 27.

[0033] The detachable assembly further comprises a second groove 22 and a limiting block 23. The second groove 22 is arranged inside the first groove 20 and away from one end of the clamping groove 12. The limiting block 23 is fixed to one end of the plug block 21 and is inserted into the second groove 22.

[0034] The baffle 26 is movably connected to the side of the box door 11. The plug block 21 is movably connected to the third groove 27.

[0035] The first groove 20 exposes a part of the clamping groove 12 and the sealing ring 13. The plug block 21 is used to fill the first groove 20 to avoid affecting the sealing effect of the sealing ring 13. The second groove 22 and the limiting block 23 have a limiting effect. The rotating shaft 24 facilitates the rotation of the baffle 26. The torsional spring 25 has a reset effect. The baffle 26 has a limiting effect. The third groove 27 has a limiting effect.

[0036] Working principle:

[0037] When the sealing ring 13 needs to be disassembled, the baffle 26 on the rotating shaft 24 is rotated to move the third groove 27 away from the plug block 21. The plug block 21 is pulled outwards to drive the limiting block 23 to move. The limiting block 23 moves out of the second groove 22. Then the plug block 21 moves out of the first groove 20. At this time, the sealing ring 13 can be buckled from the exposed first groove 20. The sealing ring 13 can be quickly removed. After the sealing ring 13 is removed, the plug block 21 is inserted into the first groove 20. The baffle 26 is loosened. Under the action of the torsional spring 25, the baffle 26 rotates. The third groove 27 is clamped on the plug block 21. The new sealing ring 13 is embedded in the clamping groove 12.

[0038] This step facilitates the quick disassembly of the sealing ring 13 and improves the maintenance efficiency.

[0039] Please refer to Figure 5 , Figure 7 The embodiment further comprises:

[0040] The moving assembly comprises a fourth groove 30, a fifth groove 31, a movable block 33, and a limiting column 34. The fourth groove 30 is arranged in the middle of one end of the plug block 21. The fifth groove 31 is arranged inside the fourth groove 30. The movable block 33 is inserted into the fourth groove 30. One end of the limiting column 34 is fixed to both sides of the movable block 33. The other end is inserted into the fifth groove 31.

[0041] The moving assembly further comprises a limiting plate 32. The limiting plate 32 is fixed to one end of the movable block 33.

[0042] The limiting plate 32 is slightly larger than the size of the larger end of the baffle 26. The limiting plate 32 is movably connected to the third groove 27.

[0043] The fourth groove 30 functions as a connection, the fifth groove 31 and the limiting column 34 function as a limitation, avoiding the moving block 33 from moving out of the fourth groove 30, the limiting plate 32 facilitates the moving block 33, and the moving block 33 can increase the contact area between the fingers and the plug 21.

[0044] Working principle:

[0045] Turning the baffle 26 away from the plug 21, the fingers buckle the limiting plate 32, drive the moving block 33 to move along the fourth groove 30, drive the limiting column 34 to move along the fifth groove 31, when the limiting column 34 moves to the outermost end of the fifth groove 31, drive the plug 21 to move, until the plug 21 moves out of the first groove 20.

[0046] This step facilitates the fingers to buckle the baffle 26.

[0047] The preferred embodiments disclosed above are only used to help explain the utility model. The preferred embodiments do not describe all the details, nor limit the utility model to the specific embodiments. Obviously, according to the content of the specification, many modifications and changes can be made. The specification selects and specifically describes these embodiments, in order to better explain the principle and practical application of the utility model, so that the person skilled in the art can well understand and utilize the utility model. The utility model is limited by the claims and the whole scope and equivalents.
