Description

Technical Field

[0001] The utility model belongs to the technical field of scientific connection between kindergarten and primary school, and particularly relates to an educational demonstration device for scientific connection between kindergarten and primary school. Background Art

[0002] In the related technology, a preschool-primary school science transition education demonstration device with publication number CN216388462U is disclosed, which includes a base and a demonstration box. Universal wheels with wheel brakes are installed at the four end corners of the bottom surface of the base. The demonstration box is installed above the base, and is characterized in that: the internal shaft of the base is equipped with a bevel gear transmission mechanism; the bevel gear transmission mechanism includes a main bevel gear and a transmission bevel gear meshing with the main bevel gear.

[0003] If the demonstration device is not disinfected after use, bacteria may remain on it. If the demonstration device is used by multiple people in succession without being disinfected, the risk of cross-infection will increase, especially in collective environments such as kindergartens or schools, where there are dense crowds and the spread of germs is more likely to occur.

[0013] The utility model has the following beneficial effects:

[0014] 1. By providing a disinfection mechanism and a wiping mechanism, after the device is used, the water pump is started, and the water pump sucks the disinfectant in the liquid storage tank into the liquid outlet pipe through the suction pipe. The disinfectant in the liquid outlet pipe flows into the infusion pipe, and then enters a plurality of connecting pipes and a plurality of nozzles through the infusion pipe, so that the disinfectant is sprayed on the surface of the demonstration table through the plurality of nozzles. Spraying the disinfectant can effectively kill potential germs and viruses. After the disinfectant is sprayed, the two hydraulic cylinders are started at the same time, and the two hydraulic cylinders drive the mounting block and the sponge to move, so that the disinfectant is evenly distributed on the surface of the device, and the residual pathogens are further removed to ensure the thorough disinfection of the device, so as to prevent the spread of pathogens, prevent cross infection, improve the hygiene level, and enhance the teaching effect, so as to provide a safe, healthy and conducive learning environment for children;

[0015] 2. By providing an adjustment mechanism, the device can be flexibly moved under the action of several moving wheels. When the device is not needed, the teacher can move the device outdoors. Since young children have weak cognition and control over the surrounding environment at a young age, collisions or accidents are prone to occur. Moving the device outdoors can reduce the risk of injury to young children in collisions. By controlling several hydraulic cylinders, the height of the device can be adjusted according to different usage requirements. Since the height and age of young children can vary greatly, corresponding adjustments can be made according to the needs of different children, ensuring that the children can comfortably observe and participate in the demonstration content, thereby providing a more personalized and appropriate learning environment.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] By providing a storage assembly, when the disinfectant in the liquid storage tank 9 is exhausted, the disinfectant can be quickly poured into the liquid storage tank 9 for storage by unscrewing the threaded cover 12, thereby providing sufficient disinfectant for the disinfection mechanism.

[0030] Among them Figure 4As shown, the wiping mechanism includes a wiping component and a fill light component. The wiping component includes a fixed plate 13 fixedly mounted on one side of two fixed frames 5 close to each other. Two hydraulic cylinders 14 are arranged on the fixed plate 13.

A mounting block 15 is fixedly mounted on the output shaft of the two hydraulic cylinders 14. A sponge 16 is fixedly mounted on the bottom of the mounting block 15. The bottom of the sponge 16 is in contact with the demonstration table 2.

[0031] By providing a wiping assembly and starting two hydraulic cylinders 14 at the same time, the two hydraulic cylinders 14 drive the mounting block 15 and the sponge 16 to move, thereby evenly distributing the disinfectant on the surface of the device and further removing residual pathogens to ensure thorough disinfection of the device.

[0032] Among them Figure 1 As shown, the fill light assembly includes two support rods 17 respectively fixedly mounted on the left and right sides of the body 1 , and fill lights 18 are respectively fixedly mounted on one end of the two support rods 17 close to each other.

Since young children have weaker cognition and control abilities for the surrounding environment at a young age, collisions or accidents are prone to occur. Moving the device outdoors can reduce the risk of injuries to young children in the event of a collision.

[0038] A specific application of this embodiment is:

[0039] Step 1: When in use, the device is first moved to a designated position, and the teacher and the child perform a demonstration teaching on the demonstration table 2. When the demonstration teaching is completed, the water pump 3 is started, and the water pump 3 sucks the disinfectant in the liquid storage tank 9 into the liquid outlet pipe 4 through the liquid suction pipe 10. The disinfectant in the liquid outlet pipe 4 flows into the infusion pipe 6, and then enters a plurality of connecting pipes 7 and a plurality of nozzles 8 through the infusion pipe 6, so that the disinfectant is sprayed on the surface of the demonstration table 2 through the plurality of nozzles 8. Spraying the disinfectant can effectively kill potential germs and viruses. After the disinfectant is sprayed, two hydraulic cylinders 14 are started at the same time, and the two hydraulic cylinders 14 drive the mounting block 15 and the sponge 16 to move, so that the disinfectant is evenly distributed on the surface of the device, and the residual pathogens are further removed to ensure the thorough disinfection of the device.

[0040] Step 2: By controlling the plurality of hydraulic cylinders 20, the plurality of hydraulic cylinders 20 simultaneously drive the plurality of circular plates 21 to move downward. Since the plurality of moving wheels 24 are in contact with the ground, when the plurality of circular plates 21 move downward, the body 1 and the demonstration table 2 are driven to move upward, so that the height of the device can be adjusted according to different usage requirements;

[0041] The third step: when the light is insufficient, turn on the two fill lights 18. The two fill lights 18 provide fill light for the device. The fill light can help improve the visibility of observation and operation, so that young children can better understand and participate in learning.
