A use method of a multifunctional cart for practical training by adopting hotel management major comprises the following specific steps: in the preparation process before the practical training cart 1 is pushed to carry out the practical training, the valve port blocking cover 28 is opened to pour quantitative disinfectant solution into the disinfectant storage box 21, and tableware or articles for daily use are placed at the end of the built-in partition plate 12;

when the practical training cart 1 is pushed to advance, the sterilization mechanism 4 is driven to perform sterilization work by the rolling drive of the sliding roller 13;

meanwhile, under the rolling drive of the sliding roller 13, the end of the rebounding mechanism 3 works simultaneously and transmits the acting force to the inside of the disinfectant storage pipe 24, so that the spraying process of the disinfectant is carried out at the end of the spraying head 25, and after the practical training cart 1 is pushed back to the placing position, the practical training work is finished.

The advantages of the invention are illustrated by the following:

the device adopts a half-open structure, namely, the arrangement of a cabinet door is deleted;

as can be seen from fig. 2, before the practical training begins, the valve port blocking cover 28 is firstly pulled out, disinfectant solution is poured into the disinfectant storage box 21, the introduction of the disinfectant solution is stopped after the target volume is reached, and the valve port blocking cover 28 is plugged back for sealing;

as can be seen from fig. 2, 3, 5 and 8, when the practical training starts, the grip 11 is held and pushed to push the practical training cart 1, at this time, the sliding roller 13 starts to move, since the output shaft end of the sliding roller 13 is fixedly connected with one end of the rotating shaft 31, the rotating shaft 31 rotates, at this time, the half-tooth meshing wheel 32 simultaneously rotates, since the half-tooth meshing wheel 32 is meshed with the meshing groove 38, and the half-tooth meshing wheel 32 is arranged in a half-tooth structure, when the non-gear end of the half-tooth meshing wheel 32 rotates to the end of the abutting push plate 35, the abutting push plate 35 is not in contact with the half-tooth meshing wheel 32, the rebound spring 34 is in a normal state, when the gear end of the half-tooth meshing wheel 32 rotates to the end of the abutting push plate 35, the abutting push plate 35 is in contact with the half-tooth meshing wheel 32, the rebound spring 34 is in an extended state, so that, during this process, when the half-tooth meshing wheel 32 rotates to the non-abutting end, the abutting push plate 35 is located at the bottom end, no movement occurs, and when the half-tooth meshing wheel 32 rotates to the gear end, the push plate 35 rises and goes up and down, the push plate 35 reciprocates;

due to the arrangement of the meshing structure, when the gear end of the half-gear meshing wheel 32 is in contact with the abutting push plate 35, if the meshing groove 38 is in contact with the convex end of the half-gear meshing wheel 32, the meshing groove 38 is lifted upwards slightly, and if the meshing groove 38 is in contact with the concave end of the half-gear meshing wheel 32, the meshing groove 38 is lowered downwards slightly, so that a reciprocating shaking function can be performed in the process of the contact between the gear end of the half-gear meshing wheel 32 and the abutting push plate 35;

as can be seen from fig. 3, 6 and 7, when the abutting push plate 35 contacts with the gear end of the half-tooth meshing wheel 32 and is lifted to the upper end, the extrusion rod 37 extrudes the disinfectant inside the disinfectant storage tube 24, because the liquid inlet valve 26 and the liquid outlet valve 27 are arranged in a one-way valve port structure, the water liquid extruded inside the disinfectant storage tube 24 can be discharged only through the spraying head 25, at this time, the disinfection spraying process is performed on the advancing path, when the abutting push plate 35 contacts with the non-gear end between the half-tooth meshing wheel 32, the abutting push plate 35 descends and pulls back due to the elastic force of the rebound spring 34, in this process, the space inside the disinfectant storage tube 24 has a void volume, and the water liquid at the end of the disinfectant storage box 21 starts to perform an automatic liquid replenishing function downwards due to the gravity;

in the process of contact between the gear end of the half-gear meshing gear 32 and the abutting push plate 35, due to the shaking generated by the movement of the gears, the newly-entered disinfectant solution in the disinfectant storage tube 24 and the originally-stored disinfectant solution are shaken and mixed, so that the precipitation phenomenon of the disinfectant solution is avoided;

as can be seen from fig. 5, when the gear end of the half-gear meshing gear 32 contacts the sterilization rotary rod 42, the sterilization rotary rod 42 starts to rotate, the coaxially connected receiving base 43 performs the concomitant rotation, and when the non-gear end of the half-gear meshing gear 32 faces the sterilization rotary rod 42, the sterilization rotary rod 42 stops rotating due to no contact, so that the receiving base 43 achieves the intermittent rotation function, and thus the two-way sterilization function of dead-corner-free sterilization and fixed-point sterilization can be achieved under the action of the sterilization lamp 44.

From what is set forth herein: according to the invention, through the structural arrangement of the internal components of the sliding roller 13, the disinfection mechanism 2 and the springback mechanism 3, the aim of intermittently spraying and disinfecting on the advancing road of the practical training cart 1 is achieved through the rolling driving of the sliding roller 13, and the functional diversity is realized through the automatic supply of disinfectant and the mixing function of new and old solutions, in addition, through the matching action among the internal components of the sliding roller 13, the disinfection mechanism 2 and the disinfection mechanism 4, under the rolling driving of the sliding roller 13, the bidirectional disinfection function of disinfection without dead angles and directional disinfection in the box is realized.
