As shown in fig. 3, 5, 6 and 7, the air duct is fully closed in the initial state, corresponding to the non-working state of the whole machine: the panel is closed and is in step contact seal with the base; the first air outlet hole of the first moving column is positioned in the first air duct and is closed, and the second air outlet hole of the second moving column is positioned in the second air duct and is also closed; the springs are in a stretched state, so that the panel is in a stretched stressed state by the springs, and further sealing between the panel and the base is ensured; the air inlet/outlet pipes which can be contacted with the outside are tightly closed in the non-working state, so that the cleaning in the cabinet body is not influenced by dust and the like outside the cabinet. As shown in FIG. 13, at this time, the first connecting block is located in the first limiting sleeve, the second connecting block is in contact with the first connecting block, and the contact surfaces of the first connecting block and the second connecting block are in the same plane with the lower surfaces of the first limiting sleeve and the inner door frame, so that the door body can be normally opened or closed.

As shown in fig. 15 to 17, the internal circulation state: corresponding to the internal circulation (disinfection/drying/anion purification, etc.) state of the whole machine: the panel is closed, and the electric putter promotes the translation of movable plate to with the panel contact, and the first venthole of first removal post and the second venthole of second removal post all open this moment, and second position sleeve and first position sleeve tip contact, and the spring is in reset state. The disinfection cabinet is opened to work, the fan is with the internal gaseous of cabinet through first air duct exhaust and get into the handle inner chamber through first venthole, thereby make its helical blade lose static balance and produce the rotation when flowing through the impeller subassembly, the rotation of impeller subassembly makes the bulb receive centrifugal force effect and then stimulate the outside extension of elastic cord, drive the rotatory whipping of bulb when causing the impeller subassembly to rotate, further increase the kinetic energy of impeller subassembly and make its rotational speed improve and rotatory persistence promote, can produce more lasting and bigger wind stand with gaseous high efficiency transmission to intake pipe one end, then get into through the second venthole on the second movable column and reenter cabinet through the second air duct, finally realize the inner loop. 1) Independently opening negative ion internal circulation to clean and refresh the odor in the cabinet body: the internal circulation air duct realizes that negative ions generated in the impeller assembly are circularly conveyed into the cabinet body, so that the odor in the cabinet body is removed, and the air in the cabinet body is fresh and odorless; 2) Opening a disinfection function: the internal circulation air duct circulates the ozone generated during the disinfection in the cabinet body, so that the ozone concentration in each part in the cabinet body is rapidly increased and reaches a dynamic balance state, and the ozone concentration in each part is uniform to ensure the disinfection effect; 3) Opening an internal circulation drying function: the hot and humid gas in the cabinet body discharged through the first air outlet hole flows through the impeller assembly and drives the impeller assembly to rotate, negative ions are simultaneously started to work and spread to the vicinity of the outer circumferential surface of the impeller through the openings on the circumferential surface of the impeller, the negative ions and the hot and humid gas discharged in the cabinet body are stirred and mixed, the hot and humid gas is fully mixed between every two blades (the rising of humidity and temperature is helpful for the rising of the concentration of the negative ions, the vapor in the air discharging process is medium-temperature gas with larger humidity and the rising of the concentration of the negative ions which can promote the diffusion out near the blades), the air field formed by the rotation of the impeller assembly blows the mixed gas to one end of the air inlet pipe rapidly, so that the flow rate of the internal circulation in the handle is enhanced, the phenomenon that the gas in the cabinet body is retained in the handle for too long time causes the cooling of the gas to generate condensed water is avoided, the negative ions enter the cabinet body to be purified and deodorized, the disinfection cabinet body is kept clean, the synchronous rotation of the impeller to cause the ball head to swing, and the impeller assembly can generate a more durable and stronger internal circulating air field. At this time, the rope and the roller drive the second connecting block to move upwards, and simultaneously the magnetic force attracts the first connecting block to move upwards together, the first connecting block is positioned in the first limiting sleeve and the second limiting sleeve, and the door body is locked and can not be opened.

As shown in fig. 18 to 20, the outer circulation state: corresponding to the external circulation (exhaust and kitchen air purification, etc.) state of the whole machine: the panel is in an open state, the electric push rod pushes the movable plate and drives the panel to translate together, the first positioning sleeve and the second positioning sleeve realize the integrity of the movable plate and the panel in the outward translation process, the first movable column is inserted into the first air duct, the second movable column is inserted into the second air duct, and the second movable column and the first movable column and the second movable column move relatively to each other to provide further support for the integral translation of the movable plate and the panel, so that the stability of movement is guaranteed. The hot and humid gas in the cabinet body is discharged through the fan, is discharged through the first venthole, and the discharge direction is the horizontal direction and towards second air duct one side, avoids hot and humid gas to directly arrange (to the user) and leads to scalding the user or lead to the user experience bad problem. The hot and humid gas blows to the impeller assembly to disturb the rotation of the impeller assembly and is mixed with the anions which are generated and diffused simultaneously, so that the hot and humid mixed gas of the rotating anions in the circumferential direction is diffused to the kitchen, the hot and humid gas is helpful for improving the concentration of the anions, and the wind farm is helpful for quickly diffusing the anions to the kitchen to realize air purification and deodorization in a wider range. 1) The external circulation air duct independently carries out blowing diffusion on negative ions, and the kitchen air is purified and deodorized; 2) The external circulation air duct simultaneously carries out the exhaust in the cabinet body and the purification and deodorization of the negative ion kitchen, and the exhaust (damp-heat) gas is helpful for improving the concentration of the negative ions, and the exhaust and the deodorization complement each other.

The second connecting block is pulled by the rope to move upwards simultaneously, the first connecting block is also pulled by the second connecting block to move upwards until the upper end face of the first connecting block is acted by the stopping part, and under the further upward pulling action of the pulling force of the rope, the first connecting block and the second connecting block are separated and fall into the first limiting sleeve to restore the initial state, as shown in fig. 21.

When the door body is in a locked state and is in internal circulation work, if accidents such as power failure or electric push rod faults occur at the moment to cause the door to be locked, the first connecting block and the second connecting block can be separated and reset into the first limiting sleeve due to the fact that the rope is pulled manually, and the door body can be restored to be unlocked.
