Description

Technical Field

[0001] This utility model relates to a scientific enlightenment device for the physical phenomena of immiscible liquids, and in particular, an educational toy. Background Technology

[0002] Children are naturally curious about the world, and new things always inspire their desire to explore. Science enlightenment can further ignite this curiosity, greatly increasing their interest in natural phenomena and scientific knowledge.

[0003] In everyday life, water and oil, which are common objects, hold amazing scientific secrets. Water is clear and flowing, while oil is light and transparent. The two cannot mix when they meet, making them typical immiscible liquids. When oil is poured into water, it quickly spreads on the surface of the water, forming a distinct oil layer. This layering phenomenon is very attractive to children, prompting them to ask, "Why can't water and oil mix?"

[0004] Therefore, it is necessary to design an educational toy that demonstrates the physical phenomena of immiscible liquids. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides an educational toy that demonstrates the physical phenomenon of immiscible liquids.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] An educational toy demonstrating the physical phenomenon of immiscible liquids includes a shell consisting of a back panel and an outer shell. A circulation device is installed inside the shell. A viewing window is provided on the front of the outer shell corresponding to the circulation device. A closed cavity for containing immiscible liquids is provided inside the circulation device. A diverter and a confluence are respectively provided on the upper and lower sides of the closed cavity. A circulating water pump is installed on the rear side of the circulation device. The inlet of the circulating water pump is connected to the confluence pipe, and the outlet pipe of the circulating water pump is connected to the closed cavity above the diverter.

[0008] The circulating flow device consists of a transparent rear plate, a front plate, and a frame that seals the edges of the rear plate and the front plate. The rear plate, the front plate, and the frame together form the closed cavity.

[0009] An LED light assembly is installed on the side of the rear panel away from the front panel.

[0010] The housing contains a control board that is electrically connected to the LED light assembly and the circulating water pump, and the side wall of the housing contains a switch that is electrically connected to the control board.

[0011] The circulating water pump is an electrically controlled water pump with adjustable flow rate. The flow controller of the circulating water pump is electrically connected to the control board and is installed at the bottom of the housing.

[0012] The enclosed cavity is located on the upper side of the diverter and has at least one liquid inlet. The outlet of the circulating water pump is connected to the liquid inlet pipe. The lowest end of the confluence part is provided with a liquid outlet, and the inlet of the circulating water pump is connected to the liquid outlet pipe.

[0013] The confluence section consists of a confluence section and a collection section. The confluence section has an inverted triangular structure with a gradually decreasing width from top to bottom. The lower end of the confluence section is connected to the upper end of the collection section, and the liquid outlet is located at the lower end of the collection section.

[0014] A manifold is installed on the upper side of the confluence portion in the enclosed cavity, and the manifold is provided with a plurality of arranged manifold holes.

[0015] The uppermost side of the viewing window is lower than the lower side of the splitter, and the lowermost side of the viewing window is higher than the upper side of the junction.

[0016] The flow divider is provided with a plurality of flow divider holes arranged in a row.

[0017] The beneficial effects of this utility model are as follows: A circulating flow device is installed inside the casing. A viewing window is provided on the front of the casing corresponding to the circulating flow device. A closed cavity for holding immiscible liquids is provided inside the circulating flow device. A diverter and a confluence are respectively provided on the upper and lower sides of the closed cavity. A circulating water pump is installed on the rear side of the circulating flow device. The inlet of the circulating water pump is connected to the confluence pipe, and the outlet pipe of the circulating water pump is connected to the upper side of the diverter in the closed cavity. The immiscible liquid is drawn into the closed cavity by the circulating water pump and then falls naturally. This transforms abstract scientific concepts into intuitive and interesting demonstrations, allowing children to personally experience and observe the properties of immiscible liquids, further satisfying their curiosity and stimulating their enthusiasm for scientific exploration.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0024] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0025] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0026] Reference Figure 1-4 An educational toy demonstrating the physical phenomena of immiscible liquids includes a shell consisting of a back plate 1 and an outer shell 2. A circulation device 3 is installed inside the shell. A viewing window 4 is provided on the front of the outer shell 2 corresponding to the circulation device 3. A closed cavity 5 for containing immiscible liquids is provided inside the circulation device 3. A diverter 6 and a confluence 7 are respectively provided on the upper and lower sides of the closed cavity 5. A circulating water pump 8 is installed on the rear side of the circulation device 3. The inlet of the circulating water pump 8 is connected to the confluence 7, and the outlet pipe of the circulating water pump 8 is connected to the closed cavity 5 above the diverter 6. The immiscible liquid is drawn into the closed cavity by the circulating water pump and then falls naturally. This transforms abstract scientific concepts into an intuitive and interesting demonstration, allowing children to personally experience and observe the properties of immiscible liquids, further satisfying their curiosity and stimulating their enthusiasm for scientific exploration.

[0027] The circulating flow device 3 consists of a transparent rear plate 16, a front plate 17, and a frame 18 that seals the edges of the rear plate 16 and the front plate 17. The rear plate 16, the front plate 17, and the frame 18 together form the closed cavity 5. That is, the entire circulating flow device 3 is transparent, allowing for a more intuitive view of the flow of immiscible liquids within the closed cavity 5.

[0028] In this embodiment, the immiscible liquid consists of two liquids: oil and water. The water is mixed with ink (the ink can be red, blue, green, etc.), which can distinguish the two immiscible liquids and make it easier for children to see the characteristics of the two immiscible liquids more intuitively. The main object of observation is the colored ink blob, while the oil is generally selected to be colorless and transparent.

[0029] An LED light assembly 19 is installed on the side of the rear plate 16 away from the front plate 17. The LED light assembly 19 is a non-color-changing light group, which serves as illumination when observing immiscible liquids. It can also rotate the color-changing light group and adjust the color through an electronic knob (which is an existing structure). When ink is mixed with different colored lights, due to the principle of color mixing, children will see the ink color change, thereby achieving a more comprehensive scientific enlightenment effect.

[0030] The housing contains a control board 20 that is electrically connected to the LED light assembly 19 and the circulating water pump 8, and the side wall of the housing contains a switch 21 that is electrically connected to the control board 20.

[0031] The circulating water pump 8 is an electrically controlled water pump with adjustable flow rate. The flow controller 22 of the circulating water pump 8 is electrically connected to the control board 20 and installed at the bottom of the housing. When the flow rate of the circulating water pump 8 is low, the circulation speed of the immiscible liquids is slow. Due to the van Wader force, adjacent ink clumps will converge together to form larger ink clumps. When the flow rate of the circulating water pump 8 is high, the circulation speed of the immiscible liquids is fast. Even adjacent ink clumps are still far apart, so they cannot converge to form larger ink clumps. Instead, more numerous and denser ink clumps fall continuously, which can further enhance the direction and effect of scientific enlightenment.

[0032] The enclosed cavity 5 is located on the upper side of the diverter 6 and has at least one inlet 9. The outlet of the circulating water pump 8 is connected to the inlet 9 via a pipe. The lowermost end of the manifold 7 is provided with an outlet 10, and the inlet of the circulating water pump 8 is connected to the outlet 10 via a pipe.

[0033] In this embodiment, there are two liquid inlets 9, so each liquid inlet 9 needs to be equipped with a 90° bend 23 for directional adjustment (e.g., Figure 3 As shown in the figure, the outlet pipe of the circulating water pump 8 is connected to a tee pipe 24, which is connected to the 90° bend pipe 23 to form a liquid flow pipeline.

[0034] Furthermore, when there is only one inlet 9, only one 90° bend 23 is needed to adjust the direction.

[0035] Furthermore, when there are three or more liquid inlets 9, each liquid inlet 9 needs to be equipped with a 90° bend 23 for directional adjustment. At the same time, the outlet pipe of the circulating water pump 8 is connected to a multi-way pipe (if there are three liquid inlets 9, the multi-way pipe is a four-way pipe; if there are four liquid inlets 9, the multi-way pipe is a five-way pipe). The multi-way pipe can be connected to the 90° bend 23.

[0036] The confluence section 7 consists of a confluence section 12 and a collection section 13. The confluence section 12 has an inverted triangular structure with a gradually decreasing width from top to bottom (it can also be an arc shape or other structure with a larger width at the top and a smaller width at the bottom). The lower end of the confluence section 12 is connected to the upper end of the collection section 13, and the liquid outlet 10 is located at the lower end of the collection section 13.

[0037] All immiscible liquids eventually converge at the aggregation point 13, where they are pumped away by the circulating water pump 8 to prevent ink clumps from accumulating and being unable to participate in the circulation, thereby reducing the total amount of ink clumps and even affecting the appearance. If the enclosed cavity is rectangular in shape, ink clumps are likely to accumulate at the two bottom corners of the enclosed cavity, making it difficult for the circulating water pump 8 to pump them away.

[0038] The enclosed cavity 5 is equipped with a manifold 14 on the upper side of the confluence portion 12. The manifold 14 is provided with a plurality of manifold holes 15. After the immiscible liquids pass through the manifold holes 15, the immiscible liquids can be more evenly distributed throughout the enclosed cavity 5, avoiding the situation where a large amount of ink clumps are gathered in one place, thus forming a large ink clump, which would affect the appearance.

[0039] The diversion component 6 is provided with a plurality of diversion holes 11 arranged in a row. When immiscible liquids flow in the closed cavity 5, a certain number of ink clumps will accumulate. The function of the diversion holes 11 is to separate these larger ink clumps again, so as to avoid the situation that the number of ink clumps is large in the first period of circulation and small in the second period of circulation.

[0040] The uppermost side of the viewing window 4 is lower than the lower side of the diverter 6, and the lowermost side of the viewing window 4 is higher than the upper side of the converging component 14. The left and right sides of the viewing window 4 cover the edges of the circulating flow device 3, which makes the internal structure invisible and more aesthetically pleasing. On the other hand, it avoids children's attention being drawn to the internal structure, thereby reducing the effect of scientific enlightenment.
