Description

Technical Field

[0001] This utility model relates to the field of toy rocket technology, specifically a hand-cranked generator rocket toy. Background Technology

[0002] In the existing technology, rocket-type toys that use high-pressure gas as a driving force are widely popular. The basic principle is to put the rocket model on a fixed vertical launch tube and release compressed air or gas generated by chemical reaction in an instant to form a high pressure several times higher in the tube cavity. This high pressure provides the rocket with an initial upward thrust, allowing it to slide along the tube wall and rise into the air. On the other hand, it also acts on the inner wall of the launch tube with the same magnitude.

[0003] Because launch tubes are often made of lightweight plastics or thin-walled metals to balance cost and weight, they are subjected to sudden increases and decreases in pressure during repeated launches. This causes fatigue cracks to gradually appear in the material's microstructure. Furthermore, outdoor use exposes the tube to large temperature differences and strong ultraviolet radiation, which easily oxidizes and embrittles the polymer chains, leading to rapid crack propagation and localized bulging deformation, ultimately resulting in tube cracking or out-of-roundness at the ends. If the tube seal fails, high-pressure leakage not only weakens the rocket's initial launch velocity, causing a sudden drop in launch altitude, but may also create retro-thrust due to gas leakage, causing the rocket to deviate or even rub against the tube wall, or cause backfire during ignition, igniting fuel and creating structural defects, increasing safety hazards. Simultaneously, the uneven guide clearance of the deformed tube to the rocket's tail fins further exacerbates friction and wobbling, requiring frequent replacement of parts or the entire launch pad, increasing operating costs and reducing operational consistency and enjoyment. In addition, the vibration and heat accompanying the high-pressure impact accelerate the aging of threaded joints, O-rings, and other sealing elements, leading to multiple leaks and complicated maintenance. Utility Model Content

[0004] The purpose of this invention is to provide a hand-cranked generator rocket toy to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hand-cranked generator rocket toy, comprising: a base, on which a feeding pipe is provided, the feeding pipe having an inner layer structure and an outer layer structure, and a vertically mounted rocket body slidably mounted on the feeding pipe; a water-storing rocket body, connected to the outer layer structure; a fuel generating structure, connected to the outer layer structure, the fuel generating structure being used to generate combustible gas and supply it to the outer layer structure; and an ignition control structure, connected to the inner layer structure, the ignition control structure being used to ignite the combustible gas inside the feeding pipe.

[0006] As described above, the hand-cranked generator rocket toy includes a central tube and a guide tube mounted on the base, with the guide tube disposed inside the central tube.

[0007] As described above, the hand-cranked generator rocket toy has a turntable rotatably mounted on the base, and a connecting seat rotatably mounted on the turntable via a connecting shaft. The central tube passes through the connecting seat and is fixed to the connecting seat.

[0008] As described above, the hand-cranked generator rocket toy has an outer layer structure formed between the central tube and the guide tube, and an inner layer structure formed inside the guide tube.

[0009] As described above, the hand-cranked generator rocket toy has a first connection port on the side of the central tube, which is connected to the water-storing rocket body via a conduit.

[0010] As described above, the hand-cranked power-generating rocket toy has a fuel-generating structure that includes a hand-cranked power generator and a water electrolysis device. The hand-cranked power generator is connected to the water electrolysis device by wires. When the hand-cranked power generator is working, it can power the water electrolysis device and electrolyze the water stored inside the water electrolysis device.

[0011] As described above, the hand-cranked generator rocket toy has a second connection port at the bottom of the central tube, which is connected to the water electrolysis device.

[0012] As described above, the hand-cranked generator rocket toy includes an ignition control structure comprising a control device and a wire connected to the control device, with the end of the wire away from the control device forming an ignition section; a sealing interface is connected to the lower end of the guide tube, and the wire passes through the sealing interface and extends to the top of the guide tube.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, by using the designed feeding pipe and water-storing rocket body, when combustible gas explodes and generates high pressure to drive the rocket body to take off, the clean water in the outer structure buffers the high pressure generated by the combustible gas explosion to a certain extent, preventing damage to the central tube structure during the explosion. Secondly, when the clean water is in the outer structure, it can exchange heat with the central tube, absorbing the heat generated by the combustible gas explosion, thus preventing overheating. Furthermore, when the clean water is in the outer structure, it creates a water seal at the bottom of the central tube and guide pipe, ensuring that the rocket body will not lack initial power due to sealing issues during the combustible gas explosion, allowing the rocket body to take off to a certain height and ensuring the playability of the rocket toy.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 3-6 As one embodiment of this utility model, the hand-cranked generator rocket toy includes: a base 7, a water-storing rocket body 9, a fuel generation structure, and an ignition control structure.

[0023] The base 7 is provided with a feeding pipe, which has an inner layer structure and an outer layer structure. A vertically arranged rocket body 6 is slidably installed on the feeding pipe. When the internal pressure of the feeding pipe increases, it can act on the rocket body 6, causing the rocket body 6 to move upward in the vertical direction and separate from the feeding pipe, thus simulating the launch process of a carrier rocket and achieving a high level of playability.

[0024] The feeding pipe includes a central pipe 4 and a guide pipe 5 installed on the base 7. The guide pipe 5 is disposed inside the central pipe 4, wherein the central pipe 4 and the guide pipe 5 form the outer layer structure, and the guide pipe 5 forms the inner layer structure. The water storage arrow body 9 is connected to the outer layer. The central pipe 4 is provided with a first connection port 401 on its side, and the first connection port 401 is connected to the water storage arrow body 9 through a conduit 8.

[0025] In this embodiment, combustible gas is pumped into the outer structure, and clean water in the water-storage rocket body 9 is also pumped into the outer structure. Under the buoyancy of the combustible gas, the combustible gas is above the clean water. When the ignition control structure works, it can ignite the combustible gas in the outer structure. The combustible gas explodes instantly, generating heat and causing the pressure in the outer structure to increase instantaneously. This increases the pressure on the rocket body 6, giving the rocket body 6 an initial upward force. Under this force, the rocket body 6 is able to fly vertically upward.

[0026] For example, in one embodiment, a turntable 10 is rotatably mounted on the base 7, and a connecting seat 12 is rotatably mounted on the turntable 10 via a connecting shaft 11. The central tube 4 passes through the connecting seat 12 and is fixed to the connecting seat 12.

[0027] It should be noted that there are two symmetrically arranged connecting shafts 11, both of which are fixed to the connecting seat 12. The connecting shafts 11 are placed horizontally in the axial direction, so that after the base 7 contacts the ground, the connecting seat 12 and the central tube 4 can rotate to different angles to enable the rocket body 6 to be launched at different angles, thereby increasing the fun. There is a certain friction between the connecting shaft 11 and the turntable 10, so that the connecting seat 12 can be kept at that angle after it rotates to a certain angle. In the specific implementation, the connecting shaft 11 can also be limited by setting an elastic buckle. This embodiment does not make specific limitations on this.

[0028] Furthermore, the position of the connecting seat 12 can be adjusted at a certain angle by the turntable 10, so that the launch angle can be changed in the horizontal direction after the connecting seat 12 and the central tube 4 are tilted, thereby further enhancing the fun.

[0029] Furthermore, the central tube 4 is used to guide the launch of the rocket body 6 and ensure the accuracy of the rocket body 6's direction of motion.

[0030] When the rocket body 6 is placed on the central tube 4, the central tube 4, the guide tube 5, and the rocket body 6 form a sealed structure, that is, the inner structure and the outer structure are in a conductive state. This means that when the outer structure generates high pressure due to the deflagration of combustible gas, the generation of high pressure will not only propel the rocket body 6 but also act on the central tube 4 body. However, since the outer structure stores clean water, when the high pressure acts on the clean water, it can push the clean water back into the water-storage rocket body 9, thereby achieving a certain buffering effect and preventing the central tube 4 itself from being damaged during the deflagration of combustible gas.

[0031] Furthermore, during the frequent launches of rocket body 6, the internal heat of the central tube 4 will accumulate due to repeated combustion, causing the central tube 4 to overheat. When the water is in the outer structure, it can exchange heat with the central tube 4 to a certain extent, thereby absorbing the heat generated by the deflagration of combustible gas in the central tube 4, thus preventing the central tube 4 from overheating.

[0032] Furthermore, when water is in the outer layer, it can create a sealing effect on the bottom of the central tube 4 and the guide tube 5, i.e., a water seal. By improving the sealing of the bottom of the central tube 4 and the guide tube 5, it can be ensured that the rocket body 6 will not have insufficient initial power due to sealing issues during the combustion of combustible gas, allowing the rocket body 6 to take off to a certain height and ensuring the playability of the rocket toy.

[0033] Based on the above settings, firstly, when the combustible gas explodes and generates high pressure to drive the rocket body 6 to take off, the water in the outer layer can buffer the high pressure generated by the combustible gas explosion to a certain extent, preventing damage to the structure of the central tube 4 during the explosion. Secondly, when the water is in the outer layer, it can exchange heat with the central tube 4, thereby absorbing the heat generated by the combustible gas explosion and preventing overheating of the central tube 4. In addition, when the water is in the outer layer, it can create a water seal effect on the bottom of the central tube 4 and the guide tube 5, ensuring that the rocket body 6 will not lack initial power due to sealing issues during the combustible gas explosion, allowing the rocket body 6 to take off to a certain height and ensuring the playability of the rocket toy.

[0034] Please see Figures 1-2 The fuel generating structure is connected to the outer structure and is used to generate combustible gas and transport it to the outer structure. The fuel generating structure includes a hand-cranked generator 1 and a water electrolysis device 2. The hand-cranked generator 1 is electrically connected to the water electrolysis device 2. When the hand-cranked generator 1 is working, it can power the water electrolysis device 2 and electrolyze the water stored inside the water electrolysis device 2. The bottom of the central tube 4 is provided with a second connection port 402, which is connected to the water electrolysis device 2.

[0035] In this embodiment, by rotating the handle of the hand-cranked generator 1, the hand-cranked generator 1 can be driven to work. During this process, the hand-cranked generator 1 can generate electricity and send it to the water electrolysis device 2. The water electrolysis device 2 stores a water sample, which allows the water electrolysis device 2 to electrolyze the water sample, thereby generating hydrogen and oxygen. The hydrogen and oxygen enter the second connection port 402 through the pipeline and finally enter the outer structure to realize the injection of combustible gas.

[0036] In the above process, when in use, the combustible gas can be generated and refueled simply by turning the handle of the hand-cranked generator 1, which shortens the amount of preparation work before the rocket body 6 takes off, avoids a lot of preparation work before the rocket body 6 takes off, and reduces the playability of the rocket toy.

[0037] The ignition control structure is connected to the inner layer structure and is used to ignite the combustible gas inside the feed pipe. The ignition control structure includes a control device 3 and an electric wire connected to the control device 3. The end of the electric wire away from the control device 3 forms an ignition part. The lower end of the guide tube 5 is connected to a sealing interface 403. The electric wire passes through the sealing interface 403 and extends to the top of the guide tube 5 so that when the control device 3 is activated, the end of the electric wire away from the control device 3 (ignition part) can generate an electric spark and ignite the combustible gas in the outer layer structure.

[0038] Among them, the sealing interface 403 can ensure the sealing performance between the outer structure and the outside of the central tube 4.

[0039] In this embodiment, pressing the control device 3 causes the ignition part of the wire to generate an electric spark, which ignites the combustible gas in the outer structure, thereby generating high voltage and driving the rocket body 6 to take off.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
