Description

Technical Field

[0001] This invention relates to the field of children's amusement facilities technology, and in particular to a rotating water jet windmill structure. Background Technology

[0002] Inflatable castles, as a common children's amusement facility, are widely distributed in various amusement venues due to their diverse shapes, easy construction, and high level of fun. With the continuous improvement of children's play needs, simply relying on inflatable structures is no longer sufficient to meet children's play experience requirements; inflatable castles with water-spraying functions are gradually becoming a new market trend.

[0003] Currently, existing technologies for adding water spraying functions to inflatable castles mainly include the following forms: First, water pipes are fixed to the outer wall of the inflatable castle using Velcro or adhesive tape, and a mounting wall is set on the castle surface. The nozzles are mounted on the mounting wall using Velcro, and the water pipes are connected to the nozzles to achieve water spraying; Second, water spray plates are fixedly connected to both sides of the inflatable castle body, and a rotating seat is rotatably connected to the top of the water spray plate. The top of the rotating seat is fixedly connected to the spray nozzle, and the reciprocating swing of the nozzle is achieved by a servo motor driving the transmission gear and the bidirectional rack; Third, a rotating water sprayer is mounted on the inflatable toy through a base, and the rotating nozzle is automatically rotated by the impact of water flow.

[0004] However, the existing solutions still have many shortcomings. First, the method of attaching water pipes to the outer wall of the inflatable castle using Velcro or adhesive is not secure enough. Under the impact pressure of water flow or the pulling and touching of children during play, the water pipes and nozzles are prone to detachment. Furthermore, the haphazard arrangement of water pipes on the castle's outer wall not only affects aesthetics but also poses a tripping hazard for children. Second, while the solution of using a servo motor to drive the nozzles to swing can change the direction of the water spray, it requires an additional motor and transmission mechanism, increasing product cost and energy consumption. Moreover, in the humid environment of the inflatable castle, the electrical equipment poses safety hazards, and reliability is difficult to guarantee. Third, although existing rotating water sprayers can rotate the nozzles, they are usually installed as independent accessories on the surface of the inflatable toy, not integrated with the main structure of the inflatable castle. The connection between the rotating structure and the castle body has poor sealing, making it prone to leakage at the connection point. Furthermore, the water spraying function and windmill rotation function of existing inflatable castles are independent of each other. There is no technical solution that integrates the rotating water spraying structure and the windmill rotation structure into the same device to achieve the simultaneous operation of windmill rotation and water spraying. Therefore, it is impossible to present the dynamic visual effect of windmill rotation and the interactive experience of rotating water spraying on the same amusement facility at the same time.

[0005] Therefore, there is an urgent need in this field for an inflatable castle water spraying device that can integrate the rotating structure and water spraying function into one, be firmly fixed, reliably sealed, and require no additional power drive, in order to solve the many problems existing in the above-mentioned prior art.

[0023] The purpose of this invention is to provide a rotating water-spraying windmill structure to solve the problems existing in the prior art.

[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1: Please see Figures 1 to 4 This invention provides a rotating water-spraying windmill structure, which includes a mounting base 1, a rotating shaft 2, windmill blades, and a water-spraying assembly 3. The mounting base 1 is used to fix the entire rotating water-spraying windmill structure onto the fabric cover of the inflatable castle body. The rotating shaft 2 is rotatably disposed within the mounting base 1. The windmill blades are fixed to one end of the rotating shaft 2. The water-spraying assembly 3 is disposed at the other end of the rotating shaft 2. The rotating shaft 2, the water-spraying assembly 3, and the windmill blades are coaxially arranged, and the water-spraying assembly 3 and the windmill blades are respectively located on both sides of the mounting base 1.

[0026] Mounting base 1 is used to achieve relative rotational connection and sealed fixation between the rotating shaft 2 and the fabric cover of the inflatable castle body. Mounting base 1 includes a fixed plate 11, a rotating plate 12, and a bearing 13 disposed between the fixed plate 11 and the rotating plate 12. The fixed plate 11 is fixedly connected to the fabric cover of the inflatable castle body. The rotating plate 12 is sleeved on the outer circumference of the rotating shaft 2 and fixedly connected to the rotating shaft 2. The rotating plate 12 is rotatably supported on the fixed plate 11 by the bearing 13, so that the rotating shaft 2 can rotate freely about its own axis relative to the fixed plate 11. The fixed plates 11 are fixedly connected to each other by fasteners such as bolts, thereby clamping and fixing the fabric cover, realizing a firm connection between mounting base 1 and the inflatable castle body.

[0027] To ensure the waterproof sealing performance at the connection between the mounting base 1 and the cloth sleeve, a sealing ring 14 is provided between the fixed plate 11 and the rotating shaft 2. The sealing ring 14 is fitted onto the outer peripheral wall of the rotating shaft 2 and abuts against the inner wall of the fixed plate 11 to prevent water from seeping outward along the gap between the rotating shaft 2 and the fixed plate 11.

[0028] The rotating shaft 2 has a hollow tubular structure with a water passage formed inside along its axial direction. The water passage runs through the rotating shaft 2 along its axial direction, with one end facing the water spray assembly 3 and connected to the water inlet pipe 31 of the water spray assembly 3, and the other end facing the external water supply system and connected to the external water supply system. One end of the rotating shaft 2 is fixedly connected to the wind turbine blades, which are evenly distributed circumferentially around the axis of the rotating shaft 2. Under the action of natural wind power, the wind turbine blades can assist in driving the rotating shaft 2 to rotate, enhancing the rotational effect.

[0029] The water spray assembly 3 includes a water inlet pipe 31, a water distribution plate 32, and a spray head 33. The water inlet pipe 31 is arranged along the axial direction of the rotating shaft 2, with one end connected to the water passage of the rotating shaft 2 and the other end connected to the water distribution plate 32. It is used to introduce water supplied by the external water supply system into the interior of the water spray assembly 3 through the water passage of the rotating shaft 2. The end of the water inlet pipe 31 that connects to the external water supply system, i.e., the water inlet end of the rotating shaft 2, is provided with a connector 311. The outer wall of the connector 311 is provided with a barbed structure 312. The barbed structure 312 is used to form a one-way snap-fit ​​engagement with the water supply pipe. That is, after the water supply pipe is fitted onto the outside of the connector 311, the barbed structure 312 can lock the inner wall of the water supply pipe, making it easy to insert but difficult to pull out. The connector 311 is also fitted with a locking nut 313, which is threaded into the connector 311 and is used to further press the outer wall of the water supply pipe after the water supply pipe is fitted into the connector 311, so as to achieve double fixation.

[0030] The water distribution plate 32 is fixedly connected to the end of the rotating shaft 2 and rotates synchronously with the rotating shaft 2. The water distribution plate 32 has a cavity structure inside, which forms a water distribution chamber. The water distribution chamber is connected to the water passage and the water inlet pipe 31 in the rotating shaft 2. Multiple water outlets are provided on the circumferential edge of the water distribution plate 32. Each water outlet is connected to the water distribution chamber and the water outlets are evenly distributed around the axis of the water distribution plate 32.

[0031] There are multiple spray heads 33, each fixedly mounted on the circumferential edge of the water distribution plate 32 and correspondingly connected to each water outlet. Each spray head 33 includes a spray body 331, inside which is provided a spiral guide groove 332. One end of the guide groove 332 is connected to the water outlet, and the other end extends to the outlet 333 of the spray body 331. After the water flows through the water distribution chamber into each water outlet, it further enters the interior of the spray body 331 of each spray head 33, and is guided by the spiral guide groove 332 before being sprayed out from the outlet 333. An arc-shaped guide surface 334 is provided at the outlet 333 of the spray head 33 as a deflection structure, and this arc-shaped guide surface 334 is set off from the radial direction of the spray head 33. After being guided by the arc-shaped guide surface 334, the water is sprayed out in a direction deviating from the radial direction. Under the impact of the water flow, a reaction torque is generated, which drives the water nozzle 33 and the water distribution plate 32 to rotate around the axis of the rotating shaft 2. This causes the water nozzle 33 to drive the water spray assembly 3 and the rotating shaft 2 to rotate around the axis of the rotating shaft 2. The windmill blades rotate synchronously with the rotating shaft 2.

[0032] The assembly process and working principle of the present invention will be described below with reference to the accompanying drawings.

[0033] During assembly, first, the rotating shaft 2 is passed through the fixed plate 11 and bearing 13 of the mounting base 1, so that the rotating shaft 2 is rotatably supported in the mounting base 1. The sealing ring 14 is fitted onto the outer peripheral wall of the rotating shaft 2 and abuts against the inner wall of the fixed plate 11. The cloth sleeve is clamped and fixed using fasteners. The windmill blades are fixedly connected to the end of the rotating shaft 2 facing outwards from the inflatable castle. The water distribution plate 32 is fixedly connected to the end of the rotating shaft 2, so that the water distribution chamber of the water distribution plate 32 is connected to the water passage of the rotating shaft 2. Each spray head 33 is installed at the water outlet on the circumferential edge of the water distribution plate 32, so that the guide groove 332 of each spray head 33 is connected to the corresponding water outlet. The external water supply pipe is fitted onto the outside of the connector 311, so that the barbed structure 312 is inserted into the inner wall of the water supply pipe, and then the locking nut 313 is tightened to press and fix the water supply pipe.

[0034] During operation, water supplied by the external water supply system enters the connector 311 through the water supply pipe, then flows into the water passage of the rotating shaft 2, and flows along the water passage to the water distribution chamber of the water distribution plate 32. After being divided in the water distribution chamber, the water flows into the spray body 331 of each spray head 33 through each outlet channel. After being guided by the spiral guide groove 332 inside the spray body 331, the water is sprayed out from the arc-shaped guide surface 334 at the outlet 333. Because the arc-shaped guide surface 334 is deviated from the radial direction of the spray head 33, the water sprays out and generates a tangential reaction force on the spray body 331. This reaction force drives each spray head 33, together with the water distribution plate 32, to rotate around the axis of the rotating shaft 2. The rotation of the water distribution plate 32 drives the rotating shaft 2 to rotate synchronously, and the rotating shaft 2 in turn drives the windmill blades to rotate synchronously. During this process, each water nozzle 33 continuously sprays water and rotates circumferentially around the axis of rotation 2, thus creating a rotating water spray effect inside the inflatable castle. Simultaneously, the windmill blades located outside the inflatable castle rotate synchronously with the axis of rotation 2, presenting a dynamic visual effect of a rotating windmill. In the absence of external water supply, the windmill blades can also drive the axis of rotation 2 under natural wind force, causing the water spray assembly 3 to rotate accordingly. With external water supply, the reaction force generated by the water flow is the primary driving force, while wind force serves as an auxiliary driving force; the two can work together to drive the axis of rotation 2.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] It should be noted that the components mentioned in the above embodiments are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0037] This invention has illustrated its principles and implementation methods using specific examples. The descriptions of these embodiments are merely illustrative of the method and its core ideas; furthermore, those skilled in the art will recognize that modifications may be made to the specific implementation methods and application scope based on the principles of this invention. Therefore, the content of this specification should not be construed as limiting the invention.
