[0021] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 4 As shown, a drying rack and an electric constant temperature blast drying box provided by an embodiment of the utility model include a rotating shaft 1, and a water baffle 2 is fixedly connected to the upper end of the rotating shaft 1. The water baffle 2 is circular and made of stainless steel. A water tank is provided at the upper end of the water baffle 2. The water tank is used to store condensed water falling from the cavity of the body 6. In the process of drying items by the electric constant temperature blast drying, water will evaporate due to heat to form water vapor. When the water vapor encounters the inner wall of the body 6 with a lower temperature, it will be cooled and condensed into liquid water. In order to prevent the condensed water from falling and making the items on the storage rack 3 damp again, the water baffle 2 is provided to block and collect the condensed water.

[0023] A rack 3 is rotatably connected to the middle of the rotating shaft 1. The rack 3 is circular and made of stainless steel and high temperature resistant material. A placement groove is provided on the rack 3 to place objects that need to be dried to prevent the objects from falling off the rack 3.

[0024] A thread is provided in the middle of the rotating shaft 1, and a threaded hole matched with the thread on the rotating shaft 1 is opened in the middle of the rack 3. The rack 3 is threadedly connected to the rotating shaft 1, and the rack 3 can rotate on the rotating shaft 1. After the rack 3 is rotated, the rack 3 will move up and down due to the thread on the rotating shaft 1, thereby changing the height of the rack 3. The rack 3 can also be adjusted according to the size of the objects to be dried, so that objects of different sizes can be placed on the drying rack.

[0025] A locking assembly 5 is provided at the bottom end of the rack 3, and the locking assembly 5 is used to fix the rack 3. The locking assembly 5 includes a fixing block 501, and the fixing block 501 is fixedly connected to the bottom of the rack 3. An avoidance hole is provided in the middle of the fixing block 501, and the rotating shaft 1 is provided in the avoidance hole. The fixing block 501 rotates on the rotating shaft 1. A hole is provided on one side of the fixing block 501, and a locking screw 502 is provided in the hole. The locking screw 502 is used to limit the rotation of the fixing block 501.

[0026] When the locking screw 502 is tightened, the rack 3 will be fixed on the rotating shaft 1 by the locking assembly 5 and cannot move. When the locking screw 502 is loosened, the rack 3 can be rotated, and the height of the rack 3 can be adjusted. After the height of the rack 3 is adjusted, the locking screw 502 can be tightened to fix the rack 3.

[0027] A motor 4 is provided at the top of the rotating shaft 1, and the motor 4 is used to drive the rotating shaft 1 to rotate. After the motor 4 is started, the rotating shaft 1 will rotate, and the rotation of the rotating shaft 1 drives the storage rack 3 to rotate. During the drying process of the electric constant temperature blast drying box, the motor 4 is always in the started state, so that the storage rack 3 always rotates with the rotating shaft 1, so that the items on the storage rack 3 are always rotating, so that the items are heated evenly.

[0028] An electric constant temperature blast drying box includes the above-mentioned drying rack and a body 6. The body 6 is a rectangular parallelepiped and is made of stainless steel. Of course, the shape of the body 6 is not limited to a rectangular parallelepiped, and can also be set to other shapes such as a cube. A cavity is opened in the body 6, and a rotating shaft 1 is rotatably connected in the cavity. A motor 4 is fixedly connected to the body 6, and the body 6 is rotatably connected to a box door 10.

[0029] A hinge 9 is fixedly connected to the body 6 , and the hinge 9 is fixedly connected to the door 10 . The door 10 rotates on the body 6 via the hinge 9 . A handle 11 is fixedly connected to one side of the door 10 , and the handle 11 is used to open the door 10 .

[0030] A control console 7 is fixedly connected to one side of the body 6. The control console 7 is a rectangular parallelepiped. A control system, electronic components, a processor, etc. are provided in the control console 7. A button 8 is provided on the control console 7. The button 8 includes but is not limited to a start and stop button for controlling the motor 4, a start and stop button for controlling the electric constant temperature blast drying box, and a usage time control button. A display is also provided on the control console 7 for displaying the temperature and drying time in the electric constant temperature blast drying box.

[0031] When using the utility model, first open the box door 10 through the handle 11, and observe whether the items to be dried can be placed in the drying rack. If not, loosen the locking screw 502, adjust the height of the rack 3 so that the items can be placed in the drying rack, and then tighten the locking screw 502. After placing the items on the rack 3, close the box door 10, and then start the electric constant temperature blast drying oven to dry the items, and then start the motor 4 to rotate the rack 3. The rack 3 continues to rotate so that the items can be heated evenly. During the drying process, the condensed water generated on the body 6 will be blocked and collected by the water baffle 2 to prevent the condensed water from causing the items to get wet again. If the items can be placed in the drying rack, they can be directly dried.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
