Detailed Embodiments

[0029] The following further describes the specific technical solutions of the present utility model with reference to the accompanying drawings, so as to facilitate those skilled in the art to further understand the present utility model without constituting a limitation to its rights.

[0030] Example 1, referring to Figures 1-4 , a door extrusion type single-door sealing device for a cleaning and disinfection machine, including;

[0031] A door track fixing frame 1, which is arranged at the hatch of the cleaning and disinfection machine cylinder body 2. A door sealing strip 3 is fixedly arranged at the hatch of the cleaning and disinfection machine cylinder body 2. The shape of the door sealing strip 3 is roughly the same as the structure at the hatch of the cleaning and disinfection machine cylinder body 2. A vertical door track 4 is embedded in the door track fixing frame 1. The door track 4 forms a roughly vertical structure. There are two vertical door tracks 4 arranged vertically, and the two vertical door tracks 4 are symmetrically arranged on the inner walls on both sides of the door track fixing frame 1;

[0032] A belt transmission mechanism, which is arranged at the top of the door track fixing frame 1. The belt transmission mechanism includes a motor 5, a driving pulley I 6, a belt I 7, a driving pulley II 8, a belt II 9 and a driven pulley 10. The model and specifications of the motor 5 can be selected according to the use requirements;

[0033] The motor 5, the driving pulley I 6 and the driving pulley II 8 are installed on the top of the door track fixing frame 1. The power output end of the motor 5 is in transmission connection with the driving pulley I 6, and the driving pulley I 6 is in transmission connection with the driving pulley II 8 through the belt I 7;

[0034] The driven pulley 10 is installed on both sides in the middle of the door track fixing frame 1, and the driven pulley 10 is in transmission connection with the driving pulley II 8 through the belt II 9;

[0035] An inner door 11 and an outer door 12, which form a roughly square plate-like structure. The inner door l1 is arranged between the hatch of the cleaning and disinfection machine cylinder body 2 and the outer door 12. The belt transmission mechanism is in transmission connection with the outer door 12 to drive the outer door 12 to move up and down. A connecting plate 13 is hinged on the side walls of the inner door 11 and the outer door 12. The connecting plate 13 forms a roughly plate-like structure. A guide wheel mechanism 14 which is fixedly arranged on the side wall of the outer door 12 and is used in cooperation with the vertical door track 4 to guide and limit the moving track of the outer door 12 is provided. The guide wheel mechanism 14 can actually be a guide wheel shaft. One end of the guide wheel shaft is connected to the side wall of the outer door 12, and the wheel shaft end of the guide wheel shaft is placed in the vertical door track 4, so that the outer door 12 can only move vertically in the vertical door track 4. Belt fixing blocks 15 are fixedly installed on both side walls of the outer door 12. The belt fixing blocks 15 form a roughly square block structure, and the belt fixing blocks 15 are fixed on the belt II 9;

[0036] It also includes an inner door top frame 16, which is formed into a roughly square plate-like structure. The inner door top frame 16 is fixed on the door track fixing frame 1 and near the hatch of the cleaning and disinfection machine cylinder 2. It is located below the inner door 11, so that when the inner door 11 moves downward to the hatch of the cleaning and disinfection machine cylinder 2, it abuts against the top surface of the inner door top frame 16. During the vertical movement of the inner door 11 without contacting the inner door top frame 16, the connecting plate 13 is in an inclined state, and its inclined state changes according to the different sizes of the connecting plate 13. At this time, the inner door 11 is attached to the outer door 12, and the main reason for this attachment is due to the self-weight of the inner door 11;

[0037] After the bottom surface of the inner door 11 contacts the top surface of the inner door top frame 16, the connecting plate 13 changes from an inclined state to a horizontal state. At this time, the inner door 11 moves away from the outer door 12 and presses against the door sealing strip 3;

[0038] In order to prevent the outer door 12 from pinching a person's hand during the downward movement, a grating sensor 17 for anti-pinching is fixedly installed on the bottom surface of the outer door 12, and the grating sensor 17 is horizontally installed.

[0039] The working principle of the door extrusion type single-door sealing device for the cleaning and disinfection machine in Embodiment 1 is as follows:

[0040] When it is necessary to close the door for sealing: The motor 5 is started, and through the transmission of the driving pulley I 6, the belt I 7, the driving pulley II 8 and the belt II 9, the power is transmitted to the driven pulley 10, and then the outer door 12 is driven to move downward along the vertical door track 4. Since the belt fixing block 15 is fixed on the outer door 12 and connected to the belt II 9, the outer door 12 can slide smoothly along the track. At the same time, the guide wheel mechanism 14 on the outer door 12 slides in the vertical door track 4 to ensure the smoothness and accuracy of the movement of the outer door 12. During this period, the inner door 11 also moves downward under the drive of the connecting plate 13 between its own weight and the outer door 12, but at this time the inner door 11 does not contact the inner door top frame 16, so it remains in a state of being attached to the outer door 12, and at this time the connecting plate 13 is in an inclined state;

[0041] When the outer door 12 descends to a certain position and the bottom surface of the inner door 11 contacts the top surface of the inner door top frame 16, at this time, because the inner door 11 cannot move downward while the outer door 12 is still moving downward, the end of the connecting plate 13 connected to the outer door 12 moves downward while the end connected to the inner door 11 cannot move downward, resulting in the connecting plate 13 being forced to change to a horizontal state. This change causes the movement trajectory of the inner door 11 to change from vertical to horizontal, so that it disengages from the state of being attached to the outer door 12 and presses against the door sealing strip 3. At the same time, the outer door 12 continues to move downward to the lowest position to complete the door closing action. At this time, the whole device is in a sealed state and is ready for cleaning and disinfection operations.

[0042] To prevent pinching of hands or other objects during the closing process of the door, a grating sensor 17 is installed on the bottom surface of the outer door 12. This sensor can detect whether there are obstacles below the outer door 12 and immediately stop the downward movement of the outer door 12 when an obstacle is detected, thus ensuring safe use.
