in operation, under the cooperation of the inoculating mechanism 2 and the rotating mechanism 3, the inoculating loop 201 can pass through the through slot 704 to enter the inside of the sterilizing box 702 while rotating, and the supporting plate 205 is contacted with the switch 701 on the mounting frame 706, thereby triggering the sterilizing lamp 703 to be started, sterilizing the collar 201 by the sterilizing lamp 703, increasing the sterilizing range of the sterilizing lamp 703 by the reflective mirrors 705 arranged at the two sides in the sterilizing box 702, meanwhile, the disinfection effect of the disinfection lamp 703 can be enhanced, the disinfection mechanism 7 can disinfect the docking ring 201 after inoculation is completed, so that the inoculating loop 201 does not affect the inoculating effect when inoculating the next respiratory tract secretion, therefore, the accuracy of patient diagnosis is ensured, and the sterilizing lamp 703 is turned on only when the inoculating loop 201 needs to be sterilized, which is beneficial to prolonging the service life of the sterilizing lamp 703 and avoiding the waste of resources.

The working principle is as follows:

when the inoculation device works, firstly, respiratory tract secretion needing to be inoculated is placed at the center of the upper end of an inoculation dish 104, the inoculation dish 104 is fixed at the upper end of a supporting platform 103, a motor 101 is connected with an external power supply, the supporting platform 103 and the inoculation dish 104 are driven to rotate at the upper end of a support frame 1 under the matching of a first rotating shaft 102, when the inoculation dish 104 is fixed at the upper end of the supporting platform 103, a human hand presses the inoculation dish 104 to move downwards, the inoculation dish 104 drives the supporting platform 103 to move downwards, a fixing block 301 is in sliding connection with the supporting platform 103, the fixing block 301 moves downwards along with the supporting platform 103, when the fixing block 301 moves to be contacted with the first rotating shaft 102, under the supporting action of the first rotating shaft 102, the fixing block 301 moves upwards relative to the outer surface of the supporting platform 103, and due to the matching of a U-shaped plate 302 and the fixing block 301, when the fixing block 301 moves downwards along with the supporting platform 103, the U-shaped plate 302 is pressed to move downwards, thereby pulling the connecting rope 304, at the moment, the connecting rope 304 drives the second rotating shaft 207 to rotate, so that the inoculating loop 201 can rotate to be in contact with the inside of the inoculating dish 104, the motor 101 is connected with an external power supply, the motor 101 drives the first rotating shaft 102 to rotate and simultaneously drives the one-way bearing 201 and the gear 202 to rotate, the gear 202 is meshed with the rack 203, therefore, the gear 202 can drive the rack 203 to move towards the left side on the upper end of the support frame 1 when rotating, the inoculating loop 201 and the second rotating shaft 207 are connected with the gear 202 through the fixing plate 206 and the supporting plate 205, therefore, the inoculating loop 201 can move towards the left along with the gear 202, thereby carrying out spiral inoculation on respiratory tract secretion in the inoculating dish 104, when the inoculating loop 201 moves to the leftmost side of the inoculating dish 104, the U-shaped plate 302 is not in contact with the fixing block 301, at the moment, the U-shaped plate 302 is driven to move upwards under the elastic force of the first spring 303, meanwhile, under the elastic force of the return spring 305, the second rotating shaft 207 and the inoculating loop 201 are driven to rotate, so that the inoculating loop 201 is in a vertical state, the inoculating loop 201 is not in contact with the inoculating dish 104, the damping bearing 4 is movably sleeved on the outer surface of the second rotating shaft 207, the inoculating loop 201 can rotate slowly when rotating, the phenomenon that respiratory tract secretion in the inoculating dish 104 is brought out is reduced, the motor 101 stops running after inoculation is completed, the rack 203 is pushed to move rightwards at the upper end of the support frame 1 under the elastic force of the rubber block 204, teeth on the rack 203 are connected through a one-way bearing, so that the rack 203 cannot drive the first rotating shaft 102 to rotate when moving rightwards, and when the inoculating dish 104 is placed at the upper end of the support platform 103 by a hand of a person, the hand of the person can apply downward pressure to the inoculating dish 104 under the matching of the inoculating mechanism 2 and the rotating mechanism 3, therefore, the inoculation dish 104 can drive the supporting platform 103 to move towards the inside of the clamping groove 601, the positioning block 605 can be extruded into the movable groove 603 by the supporting platform 103 in the moving process, when the positioning groove 606 is communicated with the movable groove 603, pressure applied by hands is not needed at the moment, the positioning block 605 can be pushed out from the inside of the movable groove 603 and pushed into the positioning groove 606 under the action of the elastic force of the third spring 604, the supporting platform 103 is fixed in the clamping groove 601 and cannot move at the moment, the supporting platform 103 can drive the fixing block 301 to move downwards while moving downwards, the sliding block 501 is uniformly and fixedly arranged on the outer surface of the fixing block 301, therefore, the fixing block 301 can drive the sliding block 501 to slide in the mounting groove 504, the mounting groove 504 is in an inclined shape, and when the sliding block 501 slides downwards, the clamping block 503 can be driven to rotate by taking the third rotating shaft 502 as the center of a circle, so that the upper end of the clamping block 503 approaches towards the direction of the inoculation dish 104, the holding block 503 can hold the inoculation dish 104, when the U-shaped plate 302 moves, the connecting rod 607 drives the electromagnet 608 to move along with the U-shaped plate 302, when the U-shaped plate 302 moves to the leftmost side, the electromagnet 608 has magnetism, and at the same time, the first rotating shaft 102 stops rotating, because the electromagnet 608 and the locating block 605 attract each other, the electromagnet 608 can move the locating block 605 out of the locating groove 606 and into the movable groove 603, under the elastic force of the second spring 602, the supporting platform 103 is pushed to move upwards to push the inoculation dish 104, and at the same time, the fixed block 301 drives the slide block 501 to slide upwards in the mounting groove 504, so that the upper end of the holding block 503 moves away from the inoculation dish 104, and under the cooperation of the inoculation mechanism 2 and the rotating mechanism 3, the inoculating loop 201 passes through the through groove 704 to enter the inside of the sterilizing box 702 when rotating, simultaneously the switch 701 contact on backup pad 205 and the mounting bracket 706 to triggering sterilamp 703 and opening, sterilamp 703 disinfects ring 201, and the mirror 705 of the inside both sides installation of disinfect box 702 can increase the sterile scope of sterilamp 703, can strengthen the disinfection effect of sterilamp 703 simultaneously.
