When the relative rotation causes the first port 3 ii to at least partially overlap with the second opening 322, and the third opening outside the box 10 is closed, the opening is closed. For the first working position; when the relative rotation causes the first opening 311 and the second opening 322 to be staggered, and the first opening is no longer sealed, the opening is the second working position, which is Under the action of the fan 33, the outside air can enter the inner duct 32 through the third opening, and then enters the outer duct 31, and then flows out from the air outlet 11 to the outside.

When the relative movement is axially relative movement, as shown in FIGS. 1 and 5; the inner duct 32 is movable back and forth between the inside and the outside of the casing 10, and when the inner duct 32 is moved, the second opening 322 is entered. The inside of the casing 10 and at least partially coincident with the first opening 311, which is the first working position (the state of the first working position shown in FIG. 5), the windshield 323 acts to isolate the outside air _; The inner air duct 32 moves so that the second opening 322 is offset from the first opening 3 ii. When the second opening 322 moves out of the box 10, the first opening 3 ii is blocked by the inner duct wall, and the air is used by the fan 33. The inner air duct 32 can be inserted into the outer air duct 31 from the second opening 322, and then flows into the outer air duct 31. After being heated by the electric heating wire, it flows out from the outer air duct 31, and then flows out to the outside through the air outlet 11 of the casing 10.

As shown in FIG. 2 and FIG. 2, one end of the outer air duct 31 provided with the first opening 311 (hereinafter referred to as the right end) is mounted on the right side wall of the casing 10 through a flange 35, preferably in the lower right side wall. The right side surface of the flange 35 is provided with a cylindrical mechanism with an opening 34. The second opening 322 is opposite to the opening 34 when the second work position is located, so that the outside air directly passes through the second opening at the mouth 34. 322 enters the inner duct 32. The cylindrical hook is provided with a support plate 36 and two chutes 37 at the same level. As shown in FIG. 1 , FIG. 3 and FIG. 6 , the right side surface of the wind deflector 323 of the inner air duct 32 is provided with a mounting wing 38 . The two ends of the mounting wing 38 are respectively matched with the two sliding slots 37 , and can be slid along The groove 37 slides to ensure axial movement of the inner duct 32, and the wind deflector 323 and the mounting wing 38 are located outside the casing 10. As shown in FIG. 2, FIG. 5 and FIG. 6, the movement of the inner air duct 32 is realized by the motor 60 driving the wire. The specific implementation manner is as follows: the support plate 36 is fixed with a slide rail 62, and cooperates with the slide rail 62.

As shown in FIG. 1, the transmission system includes a drive motor 51 and a drive cross 52, which is mounted on the right side wall of the case 10, preferably outside the case, and is secured above the flange 35. A driving gear 53 is disposed at each end of the driving crossbar 52, and a chain 54 is disposed on each of the two first gears 53, and the two chains are partially located outside the casing 10, and the two ends of the hanging rod 20 Connected to the two chains respectively, the driving motor 51 is directly connected to one of the first gears (the inner wall of the right side of the casing) and drives the first gear to rotate. When the first gear rotates, the driving crossbar 52 is rotated. The driving diaphragm 52 drives the other first gear (the inner wall of the left side of the box) to rotate, thereby driving the two chains to move synchronously.

In order to ensure disinfection, there is no air exchange between the cabinet 10 and the outside as far as possible. The lower part of the cabinet i0 is provided with a movable door for the entry and exit of the hanging rod 20, as shown in Fig. 1: The movable door includes two fans, due to the design principle and work. The principle is the same, only one of the doors (the rear part of the box) is described here. The movable door includes a movable panel 12, a fixed shaft 13 and an elastic member 14, and the movable panel 2 is rotatably mounted on the fixed shaft 13, elastic The member 14 is fixed between the movable panel 12 and the fixed shaft B.

When the chain drives the hanging rod 20 to move upwards into the box. In the case of the body 10, the movable panel 12 is opened by the hanging rod 20 from the bottom to the top, so that the spring is compressed, and when the hanging rod 20 enters the casing 10, when no external force is applied to the movable panel 12, the restoring force of the spring is relied upon. Panel 12 returns to its original position, ie the active door is closed. The design principle and working principle of the other movable door are the same as above, except that the direction of opening the door is from top to bottom, and will not be described here. Of course, those skilled in the art can know from the above that the movable door of the embodiment can also be a movable door that can rotate the shaft in both directions, as long as the elastic member is disposed to maintain the position of the movable panel without external force. The movable door is closed, and the lower inlet and outlet of the box are closed, so that when the hanging door enters the box, the activity One side of the panel is topped up, and the hanging rod is out of the box so that the other side of the movable panel is pushed down to achieve the same switch.

A support rod 55 can be disposed at the same level as the driving crossbar 52, and both ends of the support rod 55 are respectively A second gear 56 is mounted, and the second gear 56 also supports the movement of the chain 54. When the towel is pushed into the box, it is moved to the horizontal and the support ,, and the disinfection effect is better. After the disinfection is completed, the drying Φ may be hard or even shaped. In order to move out of the box more smoothly, a stainless steel mesh (not shown) is placed in the box. The specific position is: The lower side of the driving crossbar 52 extends in the direction in which the hanging rod moves out of the box body, passes through the side of the supporting rod 55, and then gradually extends to the lower part of the box body to form an inverted "L" shaped mesh surface with rounded corners. The left and right sides of the mesh surface are fixed on the inner walls of the left and right sides of the casing 10. In this way, when the hanging traction Φ is removed from the box, the mesh surface serves as a guide. In addition, because there is just the presence of the stainless steel wire mesh between the outer air duct and the support rod and the driving crossbar, even if the towel is dripped, the outer air duct will not be greatly affected after passing through the mesh surface.

In addition, the apparatus of the present embodiment further includes an ultraviolet disinfection system, as shown in FIG. 7: the ultraviolet disinfection system includes a control circuit (not shown) and a separate cavity 70 on the left side of the casing 10, the cavity 70 A clamping clip 71 and an ultraviolet lamp 72 are provided therein, and the jaws of the cavity 70 are mounted on the side edges 73. The control circuit is powered by the power module for controlling the switch of the ultraviolet lamp 72; the fixing clip 7] can be used for holding an object to be disinfected, such as a toothbrush.

As shown in FIG. 8, on the right side of the casing 10, there is further provided a casing 80 for cooperating with the casing 10 for covering the driving motor 51 and the heating system outside the casing 10, and in the casing. An air inlet hole 81 is formed in the 80 to ensure that the air inside and outside the box circulates in the second working position.
