Description

Technical Field

[0001] This utility model relates to the field of building block teaching aids technology, and in particular to a circuit module and circuit toy set. Background Technology

[0002] In the field of educational building blocks, existing technologies already include devices that simulate natural phenomena using electronic building blocks. For example, utility model patent CN220137845U discloses a building block-type waterspout simulation device, which includes a base, a motor, a connecting sleeve, propeller blades, and a transparent container. This device is connected to an external power source through an electrode interface on the base. The motor drives the propeller blades to rotate at the bottom of the transparent container, causing the liquid to form a vortex to simulate a waterspout phenomenon.

[0003] However, such existing technologies have the following limitations: First, mechanical transmission relies on physical contact, requiring the propeller blades to be directly sleeved onto the motor output shaft. This necessitates a rigid connection between the container and the drive component, making disassembly and maintenance inconvenient, and long-term use can easily affect transmission stability due to mechanical wear. Second, high sealing requirements are necessary. The propeller blades are located between the container and the connecting sleeve, requiring an additional sealing ring to prevent liquid from seeping into the motor, increasing structural complexity and the risk of failure. Furthermore, modularity is limited; the transparent container and drive mechanism are integrated, making it impossible to quickly replace or independently adjust the container structure, thus limiting the diversity of teaching scenarios.

[0004] Therefore, there is an urgent need for a non-contact transmission, more modular, and safer modular waterspout simulation solution to improve the reliability of teaching aids and the flexibility of teaching. Summary of the Invention

[0005] To address the aforementioned issues, the present invention aims to provide a circuit module and circuit toy kit that features non-contact transmission to avoid mechanical wear, high modularity, and convenient maintenance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This application provides a circuit module with the following technical solution: a base, an interface for plugging in a power cord is provided on the side of the base, and a standardized mating structure for plugging into a building block is provided on the bottom surface of the base, the standardized mating structure being a connecting post or a connecting groove; a magnetic suction component and a driving device for driving the magnetic suction component to rotate are rotatably arranged inside the base; a liquid storage cylinder, at least partially transparent, is detachably installed on the base, and a magnetic rotating component is provided at the bottom of the liquid storage cylinder; wherein, when the liquid storage cylinder is installed on the base, the magnetic rotating component is located within the magnetic field range of the magnetic suction component; when the driving device drives the magnetic suction component to rotate, the magnetic field coupling drives the magnetic rotating component to rotate synchronously, causing the liquid in the liquid storage cylinder to form a vortex.

[0008] Furthermore, this application also proposes that the magnetic rotating component is constructed as a bar rotor, the bar rotor being a magnet in its entirety, or that magnets are provided at both ends of the bar rotor.

[0009] Furthermore, this application also proposes that the magnetic rotating component is constructed in a capsule shape.

[0010] Furthermore, this application also proposes that the lower end of the liquid storage cylinder is constructed as an arc-shaped bottom, which can guide the magnetic rotating component to the lowest point of the liquid storage cylinder; or, the bottom of the liquid storage cylinder is constructed with a groove, and the magnetic rotating component is rotatably disposed in the groove.

[0011] Furthermore, this application also proposes that the driving device includes a drive motor and a turntable assembly connected to the output shaft of the drive motor; the magnetic attraction component is fixed on the turntable assembly.

[0012] Furthermore, this application also proposes that the turntable assembly includes a turntable base and a turntable cover disposed on the turntable base; a boss is formed on the top surface of the turntable cover facing upwards, and a groove is formed on the bottom surface of the turntable cover correspondingly to the boss; a magnetic suction component is embedded in the groove, and when the turntable cover is installed on the turntable base, the magnetic suction component is sandwiched between the turntable cover and the turntable base.

[0013] Furthermore, this application also proposes that a support cover is provided on the base, and an annular mounting port is constructed inside the support cover; the magnetic suction component is rotatably installed inside the annular mounting port, the liquid storage cylinder is detachably mounted on the annular mounting port, and the bottom of the liquid storage cylinder does not contact the magnetic suction component.

[0014] Furthermore, this application also proposes that the support cover is detachably mounted on the base, and that the turntable assembly is exposed when the support cover is removed from the base.

[0015] Furthermore, this application also proposes that the top of the liquid storage cylinder is detachably connected to a cylinder cover.

[0016] Furthermore, this application also proposes a circuit toy set, including building blocks and circuit modules as described above; the surface of the building blocks has standardized interlocking structures distributed in a matrix, and the building blocks and circuit modules are detachably connected through their standardized interlocking structures.

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0024] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

"Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0028] In the field of building block educational toys, there are devices that simulate natural phenomena using electronic building blocks, such as a building block-type waterspout simulator that uses a motor to drive a propeller blade to create a liquid vortex inside a transparent container. However, such devices require the propeller blade to be directly fitted onto the motor output shaft, resulting in a rigid connection between the container and the drive mechanism. This makes maintenance inconvenient and prone to affecting transmission stability due to mechanical wear. At the same time, a sealing structure is required between the propeller blade and the container to prevent liquid leakage, increasing complexity and the risk of failure. Furthermore, the container and drive mechanism are designed as a single unit, making it impossible to quickly replace or adjust the container structure, which limits the diversity of teaching scenarios.

[0029] To address the aforementioned issues, considering the shortcomings of existing mechanical contact transmission and sealing structures, the first step is to eliminate the physical connection between the transmission components and the liquid container. Analysis of the feasibility of magnetic field coupling revealed that non-contact power transmission can be achieved by placing magnetic components at the drive end and inside the container. Secondly, to address the need for modular expansion, a detachable structure for the base and liquid storage cylinder is proposed, employing standardized interlocking interfaces for quick connection to modular building blocks. Ultimately, it was determined that the drive unit and the magnetic rotating component would be separated, utilizing synchronous rotation of the magnetic field to drive liquid flow while avoiding direct contact between the liquid and the motor.

[0030] Example 1:

[0031] like Figure 1-5As shown, this application relates to a circuit module comprising a base 1, a driving device, a magnetic suction component 3, and a liquid storage cylinder 5. The base 1 has a power interface 2 on its side and a standardized mating structure 16 on its bottom surface. The base 1 contains a rotating magnetic suction component 3 and a driving device. The liquid storage cylinder 5 is at least partially transparent and detachably mounted on the base 1, with a magnetic rotating component 6 at its bottom. When the liquid storage cylinder 5 is mounted on the base 1, the magnetic rotating component 6 is within the magnetic field range of the magnetic suction component 3. When the driving device drives the magnetic suction component 3 to rotate, the magnetic field coupling causes the magnetic rotating component 6 to rotate synchronously, causing the liquid to form a vortex.

[0032] The standardized interlocking structure 16 refers to a physical interface that allows for quick insertion and connection with building blocks. This can be achieved using connecting posts or slots, enabling the base 1 to be flexibly assembled into different building block combinations and enhancing modular expansion capabilities. The magnetic component 3 refers to a magnetic element that can be rotated by a driving device. This can be implemented using a permanent magnet or electromagnet, transmitting power through a magnetic field. The driving device is the mechanism that provides rotational power, which can be implemented using a motor 7 or a rocker arm. The liquid storage cylinder 5 is a transparent container for holding liquid, which can be made of polycarbonate or glass. Its detachable design facilitates replacement or adjustment of the internal structure. The magnetic rotating component 6 is a magnetic drive unit located at the bottom of the liquid storage cylinder 5. This can be implemented using a bar magnet or a capsule-shaped magnet, receiving the driving force from the external magnetic component 3 through magnetic field coupling.

[0033] Specifically, the base 1 is connected to the building blocks via connecting posts or grooves at its bottom, forming a stable circuit module assembly structure. The motor 7 in the drive unit drives the turntable assembly 8 to rotate, causing the magnetic suction component 3 fixed to the turntable to rotate synchronously. When the liquid storage cylinder 5 is installed on the base 1, its bottom magnetic rotating component 6 enters the magnetic field range of the magnetic suction component 3. The change in the magnetic field generated by the rotation of the magnetic suction component 3 causes the magnetic rotating component 6 to rotate accordingly, thereby agitating the liquid inside the liquid storage cylinder 5 to form a vortex. Since there is no physical contact between the magnetic suction component 3 and the magnetic rotating component 6, mechanical wear and sealing requirements are avoided; the liquid storage cylinder 5 can be independently disassembled, facilitating the replacement of containers of different shapes or cleaning and maintenance.

[0034] Compared to existing technologies, which rely on a rigid connection between the propeller blades and the motor, this solution achieves non-contact transmission through magnetic field coupling, eliminating the risk of wear caused by mechanical contact. It also eliminates the need for a sealing structure, simplifying the device's complexity. Furthermore, while existing technologies integrate the container and drive mechanism, this solution allows for the detachable liquid storage cylinder 5, which connects to the base 1 via a standardized interface 2. This enables quick container replacement or adjustment of the block assembly, significantly improving adaptability to teaching scenarios. Through these technical solutions, this application addresses the maintenance difficulties caused by mechanical contact transmission, reduces the risk of malfunctions due to seal failure, and achieves rapid replacement of the liquid storage cylinder 5 through modular design, enhancing the functional expandability and teaching flexibility of the building block teaching aid.

[0035] In a specific implementation, the magnetic rotating component 6 is constructed as a bar rotor, which is either entirely composed of magnets or has magnets at both ends. A bar rotor refers to a rotating component with a long, strip-shaped geometric structure, which can be achieved by injection molding magnets or embedding magnets into a non-magnetic substrate. Its linear structure allows it to form a uniform coupling surface with the magnetic field. Being entirely composed of magnets means that the entire bar rotor is made of magnetic material, specifically sintered NdFeB or ferrite magnets. Full magnetization ensures that a magnetic field is generated in all areas of the rotor, guaranteeing continuous transmission of driving force. Having magnets at both ends means that magnetic units are fixed only at the two ends of the bar rotor. This can be achieved by epoxy resin bonding or snap-fit ​​fixing, creating a directional magnetic field gradient through a discrete magnetic pole layout, reducing material costs and minimizing magnetic field interference.

[0036] Specifically, the linear structure of the bar rotor extends in the same direction as the rotation of the magnetic attraction component 3, allowing the rotor to cover a larger magnetic field area within the magnetic field's range. When the entire bar rotor is a magnet, its full-length magnetization ensures a stable magnetic pole correspondence with the magnetic attraction component 3 during rotation, preventing transmission failure due to local magnetic field attenuation. When magnets are placed at both ends of the bar rotor, the magnetic field gradient formed by the two magnetic poles drives the rotor to rotate following the external magnetic field. Meanwhile, the non-magnetic middle section can be made of lightweight material to reduce inertial resistance. Both implementations achieve power transmission through non-contact magnetic coupling, eliminating the need for a mechanical connection structure at the bottom of the liquid storage cylinder 5, thus eliminating the sealing requirement and allowing for rapid separation of the cylinder from the base 1.

[0037] This application further proposes that the magnetic rotating component 6 is constructed in a capsule shape. The capsule shape refers to a cylindrical structure with rounded ends, specifically achieved by smoothly connecting hemispherical ends to a central cylindrical section, exhibiting an overall axially symmetrical form. This structure reduces the probability of contact with the irregularly shaped bottom of the liquid storage cylinder 5 by eliminating sharp edges. The effectiveness of the magnetic pole distribution refers to the symmetrical arrangement of magnet polarities along the axial direction of the capsule-shaped component. This can be achieved by embedding permanent magnets with opposite polarities at both ends of the capsule-shaped component, maintaining a stable magnetic field coupling range. Specifically, the rounded end face of the capsule-shaped magnetic rotating component 6 forms a curved surface fit with the arc-shaped bottom 51 or groove of the liquid storage cylinder 5, maintaining a uniform gap with the bottom of the cylinder during rotation. Due to the symmetrical shear force generated by fluid resistance on the rounded surface, the rotating component will not deflect due to uneven local forces. When the driving device drives the magnetic attraction component 3 to rotate, the symmetrical magnetic field distribution of the capsule-shaped component ensures that the torque transmission process is free from periodic fluctuations, avoiding speed fluctuations caused by changes in the distance between the end magnetic poles of the strip rotor. Furthermore, the capsule-shaped, edgeless design prevents turbulence in liquid environments, reducing abrupt changes in rotational resistance caused by bubble adhesion.

[0038] like Figure 3 As shown, the lower end of the liquid storage cylinder 5 is constructed as an arc-shaped bottom 51, which guides the magnetic rotating component 6 to the lowest point of the liquid storage cylinder 5. The arc-shaped bottom 51 refers to the inwardly curved surface structure formed at the bottom of the liquid storage cylinder 5, which can be achieved by injection molding. The radius of curvature of the curved surface can be adapted to the size of the magnetic rotating component 6. The magnetic rotating component 6 slides to the lowest point through gravity and the guiding effect of the curved surface. In other alternative solutions, the bottom of the liquid storage cylinder 5 is constructed with a groove, and the magnetic rotating component 6 is rotatably disposed in the groove. The groove refers to an annular or square recessed area at the bottom of the liquid storage cylinder 5, which can be formed by in-mold molding. The depth of the recess is slightly greater than the thickness of the magnetic rotating component 6, and its radial displacement is restricted by the sidewall constraint.

[0039] Specifically, the curved bottom 51 guides the magnetic rotating component 6 down the inner wall of the cylinder using its curved shape, eventually stopping stably at the bottom of the liquid storage cylinder 5. This ensures that it is aligned with the magnetic attraction component 3 inside the base 1 on the same vertical axis, maintaining the range of magnetic field coupling. The groove structure physically limits the magnetic rotating component 6 to a designated area at the bottom, preventing centrifugal force generated by liquid flow from causing it to deviate from the center of rotation. Both solutions achieve non-contact transmission stability through structural constraints, and no mechanical connection is required between the liquid storage cylinder 5 and the base 1. During disassembly, only the two need to be separated for individual cleaning or replacement of the liquid storage cylinder 5.

[0040] This solution utilizes an arc-shaped bottom 51 or a grooved structure to enable the magnetic rotating component 6 to transmit power solely through magnetic field coupling, allowing the liquid storage cylinder 5 to be independently separable and avoiding the risk of wear on mechanical connecting parts. Furthermore, while existing technologies require sealing rings to prevent liquid from seeping into the drive component, this solution eliminates the need for sealing through a non-contact transmission method, simplifying the structural complexity. Through these technical solutions, this application solves the problem of magnetic field coupling failure caused by gravitational displacement in the magnetic rotating component 6, ensuring the stability of liquid vortex formation, and simultaneously enabling quick disassembly and maintenance of the liquid storage cylinder 5, preventing contact between the drive component and the liquid and reducing the risk of failure.

[0041] In such Figure 3 and 4 In the specific embodiment shown, the driving device includes a drive motor 7 and a turntable assembly 8 connected to the output shaft of the drive motor 7, with the magnetic component 3 fixed to the turntable assembly 8. The drive motor 7 is an electric drive element that provides power for the rotation of the magnetic component 3; it can be implemented as a miniature DC motor, with its output shaft directly connected to the turntable assembly 8 to ensure stable power transmission. The turntable assembly 8 is a rotating bearing structure connected to the output end of the drive motor 7; it can be implemented as a disc-shaped component made of metal or plastic, used to fix the magnetic component 3 and expand its rotational trajectory range. The magnetic component 3 is fixed to the turntable assembly 8 by mechanical embedding or bonding to achieve synchronous rotation between the magnetic component 3 and the turntable assembly 8. Specifically, this can be achieved by setting grooves on the surface of the turntable assembly 8 and embedding magnets therein, ensuring the coaxiality of the magnetic component 3 and the drive motor 7 shaft.

[0042] Specifically, when the drive motor 7 operates, it drives the turntable assembly 8 to rotate around its axis, and the magnetic attraction component 3 fixed on the turntable assembly 8 generates a periodically changing magnetic field. When the liquid storage cylinder 5 is installed on the base 1, the magnetic rotating component 6 at its bottom is within the range of this magnetic field, achieving non-contact transmission through magnetic coupling. Since the drive motor 7 and the turntable assembly 8 constitute independent power units, the magnetic attraction component 3 does not need to form physical contact with the liquid storage cylinder 5, thus avoiding mechanical wear caused by rigid connections. The rotation plane of the turntable assembly 8 is spaced from the bottom of the liquid storage cylinder 5, allowing the liquid storage cylinder 5 to be freely disassembled without being restricted by the structure of the drive device.

[0043] This solution integrates the magnetic suction component 3 and the drive motor 7 into an independent module via a turntable assembly 8. The magnetic suction component 3 only needs to form a magnetic field coupling with the magnetic rotating component 6 inside the liquid storage cylinder 5, completely eliminating physical contact. Existing leak-proof structures such as sealing rings are unnecessary in this solution due to the absence of a contact interface, simplifying the overall structure. The turntable assembly 8 allows for controllable rotation range of the magnetic suction component 3, ensuring efficient magnetic field coupling, while providing the liquid storage cylinder 5 with installation space unaffected by the drive device. The separate design of the drive motor 7 and the turntable assembly 8 reduces dependence on the structure of the liquid storage cylinder 5, enabling different types of liquid storage cylinders 5 to be compatible with the same drive device.

[0044] Further as Figure 4 As shown, the turntable assembly 8 includes a turntable base 9 and a turntable cover 10 disposed on the turntable base 9. A boss 11 is formed on the top surface of the turntable cover 10, and a corresponding groove is formed on the bottom surface of the turntable cover 10. The magnetic suction component 3 is embedded in the groove, and when the turntable cover 10 is installed on the turntable base 9, the magnetic suction component 3 is sandwiched between the turntable cover 10 and the turntable base 9. The turntable base 9 refers to the basic support structure that supports the turntable cover 10, which can be implemented using an injection-molded plastic base with a snap-fit ​​structure on its surface for connection with the turntable cover 10. The turntable cover 10 refers to the shell component that covers the turntable base 9. Its top boss 11 is used to enhance structural rigidity, and its bottom groove is used to define the installation position of the magnetic suction component 3. The groove refers to the recessed area formed at the bottom of the turntable cover 10 corresponding to the boss 11, which can be formed by injection molding. The depth of the groove matches the thickness of the magnetic suction component 3 to limit its axial displacement. The magnetic component 3 is clamped by embedding the magnet into the groove and then clamping it in place through the assembly of the turntable cover 10 and the turntable base 9. Specifically, the edge areas of the two can be connected by screws or clips, so that the magnetic component 3 is subject to bidirectional constraint from both above and below. Specifically, the turntable cover 10 and the turntable base 9 adopt a split structure design. During assembly, the magnetic component 3 is first embedded into the groove at the bottom of the turntable cover 10, and the circumferential sidewall of the groove forms a radial limit on the magnetic component 3. The boss 11 on the top surface of the turntable cover 10 simultaneously forms the bottom groove during injection molding, ensuring that the groove and the shape of the magnetic component 3 are precisely matched. When the turntable cover 10 is fixed to the turntable base 9 by clips or screws, the top surface of the turntable base 9 and the bottom surface of the turntable cover 10 together clamp the magnetic component 3, preventing axial movement during rotation and avoiding misalignment due to vibration. The detachable feature of the turntable cover 10 allows the magnetic component 3 to be removed or replaced simply by separating the turntable cover 10 during maintenance, without disassembling the turntable base 9 or the overall structure of the drive unit.

[0045] like Figure 2-4As shown, a support cover 12 is provided on the base 1, and an annular mounting opening 13 is constructed inside the support cover 12. The magnetic suction component 3 is rotatably installed inside the annular mounting opening 13, and the liquid storage cylinder 5 is detachably mounted on the annular mounting opening 13, with the bottom of the liquid storage cylinder 5 not in contact with the magnetic suction component 3. The support cover 12 refers to the shell structure covering the surface of the base 1, which can be implemented by a split injection molded part that is snap-fitted to or sleeved with the base 1, used to isolate the magnetic suction component 3 from the external environment. The annular mounting opening 13 refers to the annular cavity formed inside the support cover 12, which can be integrally molded by injection molding, providing a rotation track for the magnetic suction component 3. The rotatable installation of the magnetic suction component 3 means that the magnet assembly is constrained to rotate inside the annular mounting opening 13, which can be implemented by bearings or low-friction plastic slide rails, ensuring that the magnetic suction component 3 rotates only around a fixed axis. The detachable mounting of the liquid storage cylinder 5 refers to the provision of a support structure at the bottom of the container that matches the shape of the annular mounting port 13. Specifically, this can be achieved by expanding the bottom of the cylinder to form an annular flange, allowing the cylinder to be stably placed on top of the support cover 12. After the support cover 12 is installed on the surface of the base 1, its internal annular mounting port 13 forms a closed rotation space, and the magnetic suction component 3 rotates stably along the inner wall of the annular mounting port 13 under the drive of the drive device. When the liquid storage cylinder 5 is placed on top of the support cover 12, the magnetic rotating component 6 at its bottom is exactly within the magnetic field coverage of the magnetic suction component 3. Because there is a gap between the bottom of the liquid storage cylinder 5 and the magnetic suction component 3, when the drive device drives the magnetic suction component 3 to rotate, the magnetic rotating component 6 is driven to rotate synchronously through magnetic coupling, thereby generating a liquid vortex inside the liquid storage cylinder 5. This gap setting ensures that the magnetic field effectively transmits torque while avoiding physical contact friction between the two. Through the above technical solution, this application achieves rapid separation and maintenance of the liquid storage cylinder 5 and the drive device, eliminates the risk of mechanical wear between rotating components, and reduces the probability of failure due to liquid leakage. The liquid storage cylinder 5 can be replaced independently without affecting the drive unit, and its container structure can be adapted to different teaching scenarios, improving the expandability of the teaching aid. The support cover 12's enclosure structure for the magnetic component 3 effectively prevents external foreign objects from entering the rotating area, ensuring transmission stability.

[0046] Furthermore, the support cover 12 is detachably mounted on the base 1, exposing the turntable assembly 8 when it is removed from the base 1. The support cover 12 protects the internal turntable assembly 8 and maintains its appearance integrity. With the support cover 12 removed, the turntable assembly 8 is directly exposed, facilitating maintenance. Once exposed, the drive motor 7 or magnetic component 3 can be directly accessed for replacement or adjustment. Specifically, the support cover 12 is fixed to the base 1 by a snap-fit ​​structure. When maintenance of the turntable assembly 8 is required, the snap-fit ​​can be manually released, and the support cover 12 can be removed entirely. At this point, the turntable seat 9 and magnetic component 3 within the turntable assembly 8 are fully exposed, allowing maintenance without disassembling the base 1 or other components. Through this technical solution, this application solves the problem of difficult maintenance of the drive assembly. After the support cover 12 is removed, the turntable assembly 8 can be directly maintained or replaced, reducing operational steps and lowering the risk of component damage. Meanwhile, the design enhances modularity, with the support cover 12 being an independent module that can be replaced with covers of different shapes or functions to adapt to the needs of different teaching scenarios.

[0047] like Figure 1-3 As shown, a cap 14 is detachably connected to the top of the liquid storage cylinder 5. The detachable connection refers to the separation of the cap 14 from the top of the liquid storage cylinder 5 through at least one of the following methods: threaded connection, snap-fit ​​engagement, or magnetic attraction. Specifically, this can be achieved by using a screw-on structure with external threads on the outer wall of the top of the liquid storage cylinder 5 and corresponding internal threads on the inner wall of the cap 14. This connection method ensures both sealing and ease of manual opening or closing. Compared to existing technologies, the transparent container of existing modular waterspout simulators uses an integrated closed design, making it impossible to open the top separately. This necessitates disassembling the entire container and its connection to the drive mechanism when changing the liquid, which is cumbersome and prone to leakage. This solution achieves independent sealing of the liquid storage cylinder 5 through the detachable cap 14. Liquid storage and retrieval operations only involve the separation and repositioning of the cap 14, simplifying the maintenance process. Through the above technical solution, this application solves the risk of liquid spillage caused by insufficient sealing of the top of the liquid storage cylinder 5, while avoiding the inconvenience of disassembling the entire container when changing the liquid in existing technologies. During the teaching demonstration, the cap 14 can be opened quickly to add dye or adjust the liquid type, enhancing the observation effect of the experimental phenomenon. Moreover, the independent sealing structure of the cap 14 does not rely on the assembly precision of the drive device, reducing the risk of liquid leakage.

[0048] Example 2:

[0049] This embodiment relates to a circuit toy set, including a building block board and the circuit modules described in Embodiment 1. The surface of the building block board has standardized interlocking structures distributed in a matrix, and the building block board and the circuit modules are detachably connected through these standardized interlocking structures. The building block board refers to the substrate structure used to support the circuit modules, specifically a plastic board with regularly arranged insertion holes or connecting posts on its surface, forming a physical connection with the circuit modules through the insertion holes. This feature allows multiple modules to be arbitrarily combined and installed, solving the problem of limited scene variety caused by the fixed layout of traditional teaching aids. The standardized interlocking structure refers to mechanically joined parts with uniform dimensions, specifically using raised cylindrical connecting posts or recessed square connecting slots, achieving quick alignment and fixation through complementary shapes. This feature, by providing dense assembly points, allows the circuit modules to be installed in any position, enhancing the spatial freedom of teaching aid combination.

[0050] This application enables quick assembly and disassembly of building blocks and circuit modules. By connecting the circuit modules described in the above scheme into the circuit, the water tornado phenomenon in the liquid storage cylinder can be observed, expanding the diversity of circuit toys and enhancing children's interest.
