Detailed Description

As shown in figure 1, the utility model comprises a cabinet body 1, an ultraviolet lamp 6 is arranged in the cabinet body 1, at least two hooks 5 are arranged at the top in the cabinet body 1, the two hooks 5 are connected by a plurality of transmission gears 4-2, a motor shaft 4-4 of a motor 4-3 is connected with one transmission gear 4-2 in a transmission way, and the motor 4-3 is fixed at the top of the cabinet body 1.

As shown in figure 2, the top of the hook is provided with an executing gear 4-1 which coaxially rotates, the executing gear 4-1 takes the top of the hook 5 as an axis, and the hook 5 is in rotating fit with the cabinet body 1 through the executing gear 4-1. In this embodiment, there are 4 transmission gears 4-2, each of which is A, B, C, D, and the motor shaft 4-4 is connected to the second transmission gear B, so as to allow the two hooks 5 to rotate in opposite directions, thereby avoiding interference between the hanging objects when they rotate. The transmission gear 4-2 is arranged between the execution gears 4-1, and the execution gear 4-1 and the transmission gear 4-2 are meshed with each other. The motor shaft 4-4 and the hook 5 are connected with the gear by a key, which is not shown in the figure.

The rotation directions of the gears which are meshed with each other are opposite, the left side hook 5 is opposite to the motor shaft 4-4, and the rotation direction is the same as that of the motor shaft 4-4 after two times of direction changes (negative to positive); similarly, the right hook 5 turns for three times, and the direction of the right hook is opposite to that of the motor shaft 4-4. It can be seen that the two hooks 5 rotate in opposite directions, i.e. rotate in opposite directions.

The axes of the transmission gear 4-2 and the execution gear 4-1 are in the same vertical plane. To reduce the speed, the diameter of the actuator gear 4-1 is larger than the diameter of the transmission gear 4-2.

The top of the cabinet body 1 is provided with a gear box 4, and a transmission gear 4-2 and an execution gear 4-1 are arranged in parallel and transversely in the gear box 4. The whole driving mechanism is integrated through the gear box 4, and the gear transmission structure is compact and easy to use and has low failure rate. The transmission gear 4-2 and the execution gear 4-1 are mounted to the gear box 4.

This scheme is reduce cost, does not use the axle installation, but utilizes the protruding position in the middle of the gear, sets up the step corresponding with protruding position on the gear in the gear box, alright block the gear. Each gear and gear box remain the axial clearance about 1mm, can guarantee the axial positioning of gear firstly, can avoid great friction secondly, and the third, when the part has great machining error, the axial clearance can be guaranteed and install smoothly. The rotating, low-speed and light-load sliding friction of the disinfection cabinet can meet the use requirements. The contact places between the gears and the gear box can be filled with lubricating media, so that the friction force is reduced. It is also possible to provide a gear shaft in the gear box 4, but the costs for production, installation and maintenance are increased.

As for the structure of the gear box 4, it is common in the prior art that the gear box 4 can be divided into an upper cover and a lower cover, the upper cover can be fixed on the top of the cabinet 1 by screws, and the upper cover and the lower cover can be fixed by screws.

The top of the cabinet 1 can be divided into a space on the top by a flat plate for placing the motor 4-3.

And the space below the cabinet body 1 also uses a flat plate to separate a space which can be used for arranging power supply control equipment and the like at the lower part, rectangular heat dissipation holes 9 can be arranged at two sides of the space for heat dissipation, and the front panel comprises a control switch 8 and a display screen 7 for displaying information, so that the cabinet is convenient and attractive. According to the product requirement, some power supply devices capable of adjusting the functions of irradiation intensity, time, timing reservation and the like can be arranged, and the switch of the rotating mechanism can be controlled. The bottom of the cabinet body 1 is provided with round anti-skidding feet 10, and the height of each foot 10 can be adjusted independently, so that the horizontal placement state is achieved.

The surface of the inner wall of the cabinet body 1 is provided with a reflective layer, generally, the cabinet body 1 is also provided with a cabinet door 2, therefore, the inner surface of the cabinet door 2 is also provided with the reflective layer, the reflective layer is made of reflective materials, the materials do not have specific rigid requirements, and only the reflective rate is required to be more than 85%, so that the reflectivity required by disinfection can be achieved. For the disinfection of the non-suspended articles, the uv reflection path is described slightly with reference to fig. 4, fully illustrating the utility of the present invention.

As shown in figure 4, the articles 11 to be disinfected are randomly put into the disinfection cabinet, the cabinet door 2 is closed, and the power supply is turned on to start the disinfection operation. The ultraviolet lamp tube 6 radiates. The ultraviolet radiation sterilizes the articles, and it is apparent that the front side of the articles 11 facing the ultraviolet lamp 6 can be completely radiation sterilized, and the radiation is not indicated. For the side and the back of the article 11, the side and the back of the article 11 can be irradiated by the reflection of the radiation ray through the reflecting materials on the side 3 of the cabinet body 1 and the inner side of the cabinet door 2. The figure shows several representative reflected rays 12, and it can be seen that the sterilization of the surface of the object by irradiation without dead angles can be achieved with good effect.
