Because the sterilizing device is a device which is in equipment, the sterilizing gas in the input cavity 1 is effectively isolated from operators, and the sterilizing gas with the concentration higher than the safety standard born by a human body can be arranged to improve the effect of sterilizing articles. As only a small amount of sterilizing gas overflows into the operation space of the operator, the health requirement of the operator can be met after the larger space is diluted by air. And positive pressure of the killing gas is maintained in the cavity, namely, external gas cannot enter the cavity, so that the killing gas in the cavity is ensured, and the reliability of killing is ensured.

In this embodiment, the flow process of the sterilizing gas in the cavity 1 is shown by arrows in fig. 5, the sterilizing gas is input into the cavity 1 from the sterilizing gas inlet 3, and flows upwards from the flowing direction of the sterilizing gas and two ends of the cavity 1, so that the sterilizing gas passes through the conveyor belt 2, contacts and kills articles on the conveyor belt 2, and flows out from the article inlets 11 and the article outlets 12 at two ends of the cavity 1, so that the articles in the cavity 1 are always kept in a killed state.

And a maintenance window 15 is provided in the chamber 1. Specifically, the opening size of the control door 13 may be adjusted by a driving motor (not shown in the drawings), for example, two plates are disposed in the vertical direction at the article inlet 11 and the article outlet 12, the output shafts of the two motors are respectively connected with the two plates in a transmission manner, and the position and the size of the control door 13 are adjusted by respectively driving the positions of the two plates. This structure of the present embodiment is also particularly suitable for the case where a plurality of conveyor belts 2 are provided in the chamber 1, and the position of the control door 13 can be adjusted to match with each conveyor belt 2, and at the same time, the opening size of the control door 13 can be adjusted to reduce the loss of the sterilizing gas.

In this way, when any one of the driving motors 22 of the driving wheel 21 and the intermediate driving wheel 24 fails and does not work, the whole conveyor belt 2 can be driven to move only by normal operation of one driving motor 22, the whole system is not stopped, and the continuity of the system operation is ensured. Furthermore, since the driving motor 22 is separated from the driving wheel 21 and the intermediate driving wheel 24, the driving motor 22 can be set to a quick-change structure, for example, the driving motor 22 and the connecting piece 4 are set to be directly detachable and inserted, and when the driving motor needs to be replaced, the fault motor is pulled out and a new driving motor 22 is inserted.

The unidirectional transmission mechanism may be a ratchet mechanism, and the ratchet mechanism is a conventional transmission mechanism, as shown in fig. 10 to 12, and comprises a ratchet assembly 61 and a pawl assembly 62, wherein the ratchet assembly 61 is in transmission connection with the driving wheel 21 or the intermediate driving wheel 24, and the pawl assembly 62 is in transmission connection with an output shaft of a driving motor. As shown in fig. 11, the pawls of the pawl assembly 62 are connected by an elastic member such as a spring to be in an extended state, and when the driving motor is operating normally, the pawl assembly 62 is driven to rotate in the arrow direction, the pawls of the pawl assembly 62 abut against the grooves of the ratchet assembly 61, and the ratchet assembly 61 is driven to rotate in the arrow direction. As shown in fig. 12, when the driving motor fails and cannot rotate, the ratchet assembly 61 and the pawl assembly 62 are separated from the unidirectional driving relationship, that is, the driving wheel 21 connected with the ratchet assembly 61 or the driving motor connected with the intermediate driving wheel 24 and the pawl assembly 62 are separated from the unidirectional driving transmission relationship, the pawl assembly 62 does not rotate, and the pawl of the pawl assembly 62 is pressed back into the groove of the pawl assembly 62 when the ratchet assembly 61 rotates, so that the ratchet assembly 61 can rotate freely along the arrow direction, thereby ensuring the normal movement of the conveyor belt 2.

The one-way transmission mechanism may be a one-way clutch mechanism, as shown in fig. 13 to 14, which includes a wheel connection section 71 and a motor connection section 72, wherein the wheel connection section 71 is in driving connection with the driving wheel 21 or the intermediate driving wheel 24, and the motor connection section 72 is in driving connection with an output shaft of the driving motor. One end of the wheel connecting section 71 is provided with a one-way groove structure which is circumferentially arranged along the outer periphery of the starting end face, and one end of the motor connecting section 72 is provided with a one-way groove structure which is matched with the one-way groove structure, as shown in fig. 13, when the driving motor connecting section 72 rotates in the direction of the arrow shown in the drawing, the wheel connecting section 71 also rotates in the direction of the arrow shown in the drawing due to the mutual limiting action of the two sets of one-way grooves. As shown in fig. 14, when the driving motor fails and cannot rotate, the wheel link 71 and the motor link 72 are separated from the unidirectional driving relationship, that is, the driving motor connected to the wheel link 71 or the intermediate driving wheel 24 and the motor link 72 is separated from the unidirectional driving transmission relationship, the motor link 72 does not rotate, and the unidirectional groove of the wheel link 71 and the unidirectional groove of the motor link 72 are separated from each other, so that the wheel link 71 can freely rotate in the arrow direction, thereby ensuring the normal movement of the conveyor belt 2. Specifically, an external elastic connection can be arranged between the motor connecting sections 72 and is in sliding connection with the output shaft of the driving motor in the axial direction, namely, the motor connecting sections 72 can slide on the output shaft, and when the driving motor works normally, the elastic piece applies elastic force to the motor connecting sections 72, so that the motor connecting sections 72 are abutted with the wheel connecting sections 71, and normal transmission is kept to form unidirectional driving; when the driving motor is abnormal, the motor connecting section 72 does not rotate, and the unidirectional groove of the wheel connecting section 71 axially extrudes the unidirectional groove of the motor connecting section 72, so that the motor connecting section 72 moves to the right in the drawing, and the wheel connecting section 71 and the motor connecting section 72 are separated from each other in a transmission relationship, so that the wheel connecting section 71 can rotate freely.

In a specific embodiment, the cavity 1 may be an integral cylindrical structure formed by integral injection molding, or may be a cylindrical structure formed by splicing a plurality of components.
