Description

Technical Field

[0001] The invention relates to the technical field of early childhood education, in particular to a scientific experience education tool for early childhood. Background Art

[0002] Preschool science experience education tools refer to educational tools designed specifically for preschoolers to help them understand scientific principles, cultivate scientific thinking and a spirit of exploration through hands-on operations, observation experiments, etc. They usually combine elements such as color, shape, and movement to attract children's attention and stimulate their thinking. They are an important part of preschool science education, and biological observation boxes are also a type of educational tools. They are filled with various small organisms or plant specimens, allowing children to observe the living habits and growth process of organisms. When the biological observation box assists preschoolers in observation education, the small animals are basically placed directly inside the observation box. Some small animals are amphibians and need to be sprayed with water regularly for moisturizing. However, the existing biological observation boxes do not have a spray mechanism to spray and moisturize the amphibians, which will cause the amphibians inside the biological observation box to be life-threatening due to dryness, reducing the practicality of the biological observation box.

[0003] In order to overcome the above defects, prior art 1 (application number CN202020210821.9, Chinese patent with application date of 2020-02-26) is a biological teaching incubator. Through the water pump, water tank and valve, the water pump sequentially passes the water in the water tank into the incubator through the water pipe, branch pipe, water pipe and water spray pipe. The two valves can control the separate water supply of the upper and lower layers, which is convenient for understanding the effect of water on plant growth. The water tank can store water, which is convenient for users to use, and improves the incubator. Ease of use; there is also prior art 2 (Chinese patent with application number CN202022641700.2 and application date of 2020-11-16). In a temperature-adjustable bat moth egg incubation box, a pull rod is arranged at the bottom of the rotating rod and pulled outward so that the bottom of the pull rod and the inside of the limit rod are separated from each other, and then the containing box is adjusted, and the water in the water tank is sent into the interior of the sprayer through a booster pump and a water supply pipe. The sprayer sprays and humidifies the incubation box body to prevent the hatching conditions from being met due to dry air.

[0004] Although the existing technology can spray and moisturize the small animals inside the biological observation box to prevent the small animals from being life-threatening due to dryness, the existing biological observation box does not have a feeding mechanism to feed the farmed small animals, and the small animals need to be fed manually on a regular basis. At the same time, there is a lack of interaction between young children and the small animals, which reduces the practicality of the biological observation box. Therefore, a kind of early childhood science experience education tool is proposed to solve the above-mentioned problems. Summary of the invention

[0010] Preferably, the outer sides of the two connecting rods are wound with return springs, and the two return springs are symmetrically arranged about the vertical center line of the discharge tray, and the outer sides of the two return springs are connected to the two sides of the inner wall of the discharge tray.

[0011] Preferably, the two sides of the worm are meshedly connected with worm wheels, and the two worm wheels are symmetrically mounted on the two sides of the biological observation box for rotation, and the output ends of the two worm wheels are connected through a turntable, and a circle of first magnets are arranged at equal angles on the outer sides of the two turntables, and the bottoms of the two circles of first magnets correspond to second magnets.

[0012] Preferably, the biological observation box has grooves at both ends thereof and is provided with rotating rods which are rotatably mounted via torsion springs, and spray plates are installed through the front ends of the two rotating rods, and second magnets are installed on the tops of the two spray plates, and the magnetic poles of the first magnet and the second magnet are opposite.

[0013] Preferably, two extrusion springs are installed in the groove on the left side of the top of the biological observation box, and the two extrusion springs have the same structure, and the outer ends of the two extrusion springs are connected to a water tank. A limit plate is positioned and installed on the left side of the top of the biological observation box, and the limit plate is rectangular in shape.

[0015] Preferably, the collision sensor is installed on the inner side of the bottom of the biological observation box, and the collision sensor is connected to an alarm via a wireless transmission module, wherein the alarm is installed on the top of the biological observation box via screws.

[0016] Compared with the prior art, the present invention has the following beneficial effects: A discharge tray is provided, and connecting rods are installed on both sides of the top of the biological observation box, and then the discharge tray is slidably installed through the bottom of the two connecting rods, and then a plug is provided on the top of the discharge tray, and at the same time, the outside of the plug is fitted with the outside of the bottom of the storage bin. When it is necessary to feed the amphibians cultured in the biological observation box in the later stage, the second beating block is driven by the rotating shaft to reciprocately beat the lifting rod. At this time, the lifting rod will drive the discharge tray to move downward through the two connecting rods, so that the plug set on the top of the discharge tray is separated from the storage bin. At this time, the food stored in the storage bin can be transported to the inside of the biological observation box through a circle of discharge ports opened on the discharge tray for feeding, which can better improve the interaction between young children and amphibians, allow young children to observe the living habits and growth process of organisms, and is more practical.

[0017] Furthermore, a discharge tray is connected to the outer sides of the two connecting rods through a return spring, and the discharge tray that is squeezed and moved downward can be elastically reset by the elastic force of the two return springs themselves, so that the plug arranged on the top of the discharge tray can block the storage bin to prevent material from falling, and the descending position of the discharge tray can be limited by the setting of two limiting balls, so as to avoid the phenomenon of feeding waste due to the discharge tray descending too deep in the later stage.

[0018] A worm gear is provided, and when it is necessary to spray water and humidify the amphibians inside the biological observation box, the child can drive the two worm gears to rotate by rotating the biological observation box. At this time, the two rotating worm gears will drive the two turntables to rotate at the same time through the transmission shaft. Because a circle of first magnets is provided at equal angles on the outside of the two turntables, the two circles of first magnets can be driven to drive the two spray discs to swing back and forth through the two second magnets through the principle of opposite magnetic field attraction while the two turntables rotate, thereby expanding the spray range of the two spray discs, and finally the positions of the two spray discs after swinging can be elastically reset through the elastic force of the two torsion springs themselves, so as to better spray water and moisturize the amphibians, and also improve the children's own hands-on ability, which is more practical.

[0019] A first beating block is provided, and a rotating shaft is connected to the outer side of the left end of the worm through a transmission assembly. The rotating shaft can be driven to rotate through the transmission assembly while the worm is rotating. Then the rotating shaft will drive the first beating block to squeeze the water tank to move its position on the left side of the top of the biological observation box, so that the water source stored in the water tank can be shaken and mixed to avoid the phenomenon of sedimentation caused by long-term storage of the water source in the water tank. The limiting plate provided on the left side of the top of the biological observation box is used to slide and limit the shaking water tank to avoid the water tank from derailing and falling. Finally, the elastic force of the two extrusion springs can be used to elastically reset the position of the water tank after the extrusion and movement, so as to facilitate repeated shaking and mixing in the later stage.

[0020] Furthermore, a float is connected to the inside of the water tank through two limit ropes, and the float can float by the buoyancy of the water source itself. When the capacity of the water source inside the water tank decreases, the float will move downward as the water source capacity decreases, and then the extrusion block provided at the bottom of the float will squeeze and collide with the collision sensor provided on the inner side of the bottom of the water tank. Then the collision sensor will transmit the information to the alarm through the wireless transmission module and sound an alarm to promptly remind the staff to add water. There is no need for manual observation of the water storage capacity regularly, and the degree of automation is better. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The present invention provides the following technical solution, a kind of scientific experience education tool for children: Embodiment 1, in order to solve the problem that the existing biological observation box 1 is not provided with a feeding mechanism to feed the farmed small animals, the small animals need to be fed manually regularly, and there is also a lack of interaction between young children and small animals, which reduces the practicality of the biological observation box 1, the following embodiment discloses: a biological observation box 1 and four-sided observation panels 2, wherein the four-sided observation panels 2 are installed on the four sides of the outer side of the biological observation box 1, and the four-sided observation panels 2 are all made of transparent anti-collision glass; a storage bin 3 is installed on the top of the biological observation box 1, and the interior of the storage bin 3 is hollow, and the bottom end of the storage bin 3 extends through to the inner side of the top of the biological observation box 1, a water tank 7 is slidably installed in the groove on the left side of the top of the biological observation box 1, and the outer end of the water tank 7 is sealed and connected to two spray plates 15 through a hose; connecting rods 22 are installed on both sides of the top of the biological observation box 1, and the outer sides of the two connecting rods 22 are slidably connected with a discharge tray 12, and a plug 19 is provided on the top of the discharge tray 12, and the plug 19 extends through to the inner side of the bottom of the storage bin 3.

[0025] A worm 4 is rotatably installed inside the biological observation box 1, and the left end of the worm 4 extends through and extends to the outside of the left end of the biological observation box 1, and a handle is installed on the left end of the worm 4, and the outside of the worm 4 is connected to a rotating shaft 6 through a transmission component 5, wherein the rotating shaft 6 is rotatably installed on the top left side of the biological observation box 1; a second slapping block 9 is installed on the right end of the rotating shaft 6, and a lifting rod 10 is correspondingly installed at the bottom of the second slapping block 9, and the lifting rod 10 is slidably installed on the top of the biological observation box 1, and the bottom end of the lifting rod 10 is connected to the top of the biological observation box 1. A discharge tray 12 is connected; a plurality of discharge openings 20 are provided at equal angles inside the discharge tray 12, and limiting balls 23 correspond to the two ends of the bottom of the discharge tray 12, and the two limiting balls 23 are arranged at the bottom ends of the two connecting rods 22, and the diameter of the connecting rods 22 is smaller than the diameter of the limiting balls 23; a return spring 24 is wound around the outer sides of the two connecting rods 22, and the two return springs 24 are symmetrically arranged about the vertical center line of the discharge tray 12, and the outer sides of the two return springs 24 are connected to the two sides of the inner wall of the discharge tray 12.

[0026] like Figure 1-Figure 6 As shown, in order to allow young children to observe the living habits and growth process of organisms, the children can manually rotate the worm 4 to drive the rotating shaft 6 to rotate through the transmission component 5. At this time, the rotating rotating shaft 6 will drive the second beating block 9 to beat and lower the lifting rod 10 extending through the top outside of the biological observation box 1. At this time, the lifting rod 10 will drive the discharge plate 12 to descend through the two connecting rods 22, and then the plug 19 set on the top of the discharge plate 12 can be driven to separate from the bottom end of the storage bin 3, so that the feed stored in the storage bin 3 can be discharged through a circle opened on the surface of the discharge plate 12. The discharge port 20 falls into the interior of the biological observation box 1 to facilitate the feeding of amphibians. It can not only allow young children to understand the living habits and growth process of organisms, but also improve their hands-on ability and the interaction between children and small animals. The two limiting balls 23 can then be used to slide and limit the discharge plate 12 that is squeezed and descended to avoid the discharge plate 12 from descending too far, which may cause the feeding and discharging speed inside the storage bin 3 to be too fast. Finally, the two reset springs 24 can use their own elastic force to elastically reset the discharge plate 12 that is squeezed and descended, so that it can be reused later, which is more practical.

[0027] Embodiment 2 is different from Embodiment 1 in that the two spray discs 15 can be reciprocated to expand the spray range of the two spray discs 15, which is more practical and discloses: The two sides of the worm 4 are meshedly connected with worm wheels 13, and the two worm wheels 13 are symmetrically mounted on the two sides of the interior of the biological observation box 1, and the output ends of the two worm wheels 13 are connected through a turntable 16, and a circle of first magnets 17 are arranged at equal angles on the outer sides of the two turntables 16, and the bottoms of the two circles of first magnets 17 correspond to the second magnets 18; the internal grooves of the biological observation box 1 are slotted at both ends and the rotating rods 14 are rotatably mounted through the torsion springs 21, and the front ends of the two rotating rods 14 are penetrated and installed with spray plates 15, and the tops of the two spray plates 15 are installed with second magnets 18, and the magnetic poles of the first magnet 17 and the second magnet 18 are opposite.

[0028] like Figure 1-Figure 4 As shown, when the child rotates the worm 4, the worm wheels 13 meshingly connected on both sides of the bottom of the worm 4 will also rotate simultaneously, because the output ends of the two worm wheels 13 are connected with a turntable 16, and the two turntables 16 can be driven to rotate while the two worm wheels 13 rotate. At this time, a circle of first magnets 17 arranged on the outer sides of the two turntables 16 will drive the spray discs 15 connected by the two second magnets 18 to swing through the principle of magnetic field attraction, and the water source stored in the water tank 7 will also be transported to the two spray discs 15 through the hose seal for spraying, which expands the spraying and moisturizing range of the two spray discs 15 and can also cultivate the curiosity and exploration desire of the children. Finally, the positions of the two rotating rods 14 can be elastically reset by the elastic force of the two torsion springs 21 themselves, so that the two spray discs 15 can cyclically swing and spray moisturize in the later stage, and the operation is more time-saving and labor-saving.

[0029] Embodiment 3 is different from Embodiment 2 in that the water source stored in the water tank 7 can be shaken and mixed to avoid the water source from settling inside the water tank 7, and the water storage amount inside the water tank 7 can also be monitored. Two extrusion springs 29 are installed in the groove on the left side of the top of the biological observation box 1, and the two extrusion springs 29 have the same structure, and the outer ends of the two extrusion springs 29 are connected to the water tank 7. A limit plate 30 is positioned and installed on the left side of the top of the biological observation box 1, and the limit plate 30 is rectangular in shape; the limiting ropes 26 are connected to the two sides of the bottom of the water tank 7, and the tops of the two limiting ropes 26 are connected to the floating plate 25, and the bottom end of the floating plate 25 is installed with an extrusion block 27, and the bottom end of the extrusion block 27 corresponds to a collision sensor 28; the collision sensor 28 is installed on the inner side of the bottom of the biological observation box 1, and the collision sensor 28 is connected to the alarm 11 through a wireless transmission module, wherein the alarm 11 is installed on the top of the biological observation box 1 by screws.

[0030] like Figure 1-Figure 9As shown, while the worm 4 drives the rotating shaft 6 to rotate through the transmission assembly 5, the first beating block 8 arranged at the outer end of the rotating shaft 6 will reciprocate and squeeze the water tank 7 to move its position on the top left side of the biological observation box 1. At this time, the water source stored in the squeezed water tank 7 can be shaken and mixed to avoid the water source from settling inside the squeezed water tank 7, so as to better spray water and moisturize the amphibians cultured in the biological observation box 1. While the water tank 7 is squeezed and moved, the limiting plate 30 arranged on the rear side of the top left end of the biological observation box 1 will slide and limit the moving water tank 7 to avoid the water tank 7 from derailing when moving, and the two squeezing springs 29 can also The water tank 7 that is squeezed and moved will be squeezed and reset by its own elastic force to facilitate the subsequent repeated movement, shaking and mixing, which is more practical. When the water storage capacity inside the water tank 7 is reduced, the float 25 will move downward due to the reduction of the water source capacity. When the squeezing block 27 set at the bottom of the float 25 squeezes and collides with the collision sensor 28 set on the inner side of the bottom of the water tank 7, the collision sensor 28 will transmit the information to the alarm 11 through the wireless transmission module and sound an alarm to remind people to add water in time. There is no need for manual regular observation of the water source storage capacity, the degree of automation is better, and the efficiency of scientific education for young children is improved, thereby completing a series of tasks.

[0031] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0032] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
