Description

Technical Field

[0001] This utility model belongs to the technical field of children's educational play devices, and in particular relates to a children's educational play device that uses a hand-cranked power cycle to autonomously construct a water spray. Background Technology

[0002] Currently, most children's educational toys on the market are static assembly or electronically interactive, lacking a comprehensive design that combines hands-on operation, power conversion, and scientific principles. Traditional water recycling toys typically use battery power or simple manual pressing methods, which have the following shortcomings:

[0003] High energy dependence: Most electric water sprinklers require batteries or external power sources, which not only increases the cost of use, but also limits children's play experience outdoors or in environments without power.

[0004] Insufficient interactivity: The water circulation process in some toys is fixed, preventing children from designing water flow paths or spray patterns independently, which reduces the fun of exploration and creation.

[0005] Limited educational value: Existing products often focus only on entertainment and fail to effectively integrate scientific knowledge such as mechanical transmission and water circulation, making it difficult to stimulate children's interest in physical principles.

[0006] Lack of collaboration: Most toys are designed for single-player operation and lack mechanisms for multi-player collaboration, which is not conducive to developing children's cooperative abilities. Utility Model Content

[0007] The purpose of this invention is to provide a hand-cranked, self-constructing water-spraying educational toy for children, in order to solve the aforementioned technical problems.

[0008] To achieve the above objectives, the specific technical solution of this utility model for a hand-cranked, self-constructing water-spraying educational toy device for children is as follows:

Children can connect multiple arc-shaped water pipes by selecting different connectors to form various shapes, and connect them with the four-way interface of the water outlet pipe and the universal water pipe to form a loop. The arc-shaped water pipes have one or more small holes that can spray water, and different water spray shapes and effects can be achieved according to different shapes.

[0016] Furthermore, one end of the universal water pipe is fixed inside the water circulation box, while the other end can be universally adjusted to allow water to flow into the next device, forming a loop.

[0017] This invention relates to a hand-cranked, self-constructing, water-spraying educational toy device for children, which has the following advantages:

[0018] 1. Cultivate hands-on skills and creativity

[0019] Children can independently assemble curved water pipes using connectors to create personalized water spray shapes, such as circular fountains and spiral water jets, stimulating their imagination and spatial construction abilities.

[0020] 2. Intuitive learning of scientific principles

[0021] By using a hand-cranked generator to drive a water pump, children can directly observe the conversion process from mechanical energy to electrical energy to the kinetic energy of water, and understand the basic principles of energy transfer and water circulation.

[0022] The design of the water jet allows children to explore the relationship between water pressure and the shape of the water jet, enhancing their understanding of fluid dynamics phenomena.

[0023] 3. Environmentally friendly and energy-saving, with no dependence on power sources.

[0024] Powered by hand-cranked generator, it requires no batteries or external power source, reducing operating costs and fostering children's environmental awareness. It is suitable for outdoor or power-free environments.

[0025] 4. Promote cooperation and social interaction

[0026] The device allows two people to crank the hand-cranked generator simultaneously, requiring children to work together to control the water flow intensity and spray effect, thus cultivating teamwork and communication skills through the game.

[0027] In conclusion, this utility model combines educational, entertaining, and interactive elements, helping children learn scientific knowledge through play while also developing their hands-on skills and teamwork spirit, thus possessing broad market application prospects.

[0031] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a hand-cranked, self-constructing water-spraying educational toy device for children.

[0032] like Figure 1 Figure 2 As shown, this utility model discloses a hand-cranked, self-constructing water-spraying educational toy device for children, comprising a water circulation box 1, a hand-cranked generator 2, a water pump 3, a self-constructing water pipe 4, and a universal water pipe 5. The water pump 3 is located in a water source or in the previous water circulation device, and delivers water to the water circulation box 1 through an outlet pipe 31. The hand-cranked generator 2 is fixedly installed on the outside of the water circulation box 1 and electrically connected to the water pump 3. The self-constructing water pipe 4 is located inside the water circulation box 1, allowing children to construct their own shapes and connecting to the outlet pipe 31 and the universal water pipe 5. The self-constructing water pipe 4 has spray holes on its wall. The hand-cranked generator 2 drives the water pump 3 to draw water, which is then sprayed through the self-constructing water pipe 4. The water in the self-constructing water pipe 4 flows out through the universal water pipe 5 to the next water circulation device, thus achieving water circulation.

[0033] The water circulation box 1 and the water vortex box 1 have a drain outlet 11 at the bottom, which is a press-to-drain outlet for draining water. A storage box 6 can be hung on the side wall for temporarily storing children's items, making it convenient for children to play.

[0034] The hand-cranked generator 2 includes one or more, preferably two, which are fixedly installed on both sides of the water circulation box 1, allowing two children to operate it simultaneously and experience cooperation and fun.

[0035] The outlet pipe 31 of the water pump 3 and the universal water pipe 5 are equipped with one or more four-way interfaces 32 for connecting the self-constructed water pipe 4.

[0036] The self-constructed water pipe 4 includes multiple arc-shaped water pipes 41 and multiple connectors 42. The connectors 42 include two-way pipes, three-way pipes, and four-way pipes. Children can connect multiple arc-shaped water pipes 41 by selecting different connectors 42 to form various shapes, and connect them with the outlet pipe 31 and the four-way interface 32 of the universal water pipe 5 to form a loop. The arc-shaped water pipes 41 have one or more small holes that can spray water. Different spray shapes and effects can be achieved according to different shapes.

[0037] One end of the universal water pipe 5 is fixed inside the water circulation box 1, and the other end can be adjusted in all directions to allow water to flow into the next device, forming a loop.

[0038] The usage process is as follows:

[0039] Self-assembly: Children can choose from arc-shaped water pipes 41, two-way pipes, three-way pipes 4, or four-way pipes to assemble according to their own creativity. Multiple arc-shaped water pipes 41 can be connected into any shape, such as a ring or snake shape, using connectors 42 such as two-way pipes or three-way pipes. Connect the inlet end of the assembled self-built water pipe 4 to the four-way interface 32 of the outlet pipe 31, and connect the outlet end to the universal water pipe 5 to form a closed loop.

[0040] Starting device: One or two children simultaneously crank the hand-cranked generator 2, generating electricity through mechanical energy to drive the water pump 3. The water pump 3 draws water from the water circulation box 1 and delivers it through the outlet pipe 31 to the self-constructed water pipe 4.

[0041] Water spraying and observation: After water enters the self-constructed water pipe 4, it will spray out from the spray holes on the pipe wall, forming different water spraying effects such as fountains and water mists. The specific effect depends on the shape built by the child. The sprayed water falls back into the water circulation box 1, and some of the water in the self-constructed water pipe 4 flows out through the universal water pipe 5 and enters the next water circulation device, such as another water circulation box, to continue to be used, thus realizing circulation.

[0042] Adjustment and interaction: Children can change the direction of water flow or link with other devices by adjusting the angle of the universal water pipe 5.

[0043] If drainage is needed, press the drain port 11 at the bottom of the water circulation box 1 to quickly drain the water accumulated in the water circulation box 1.

[0044] The storage box 6 on the side wall can be used to temporarily place small toys or tools, making them easy for children to access.

[0045] Through the above steps, children can learn the principles of water circulation while enjoying the fun of creation through hands-on building and cooperative shaking.
