Technical Field
[0001] This invention relates to the field of spray device technology, specifically to a nozzle for water mist spraying on a 4D platform seat. Background Technology
[0002] 4D platform seats are a key component of 4D motion cinemas. They can be computer-controlled to produce different special effects according to the film's storyline. When water-related scenes such as rain, fountains, or waves appear in the movie, water mist can make the audience feel as if they are in the rain or by the water, enhancing the realism of the scene and the immersion of the viewing experience, giving the audience a richer sensory experience and allowing them to better immerse themselves in the movie's plot.
[0003] Current 4D cinema seats emit water mist in a monotonous pattern. Traditional nozzles are mostly cone-shaped sprays, which cannot simulate special water patterns such as the "sheet-like rain curtain" under a waterfall or the "linear splash" of water spraying from a pipe. The core characteristics of cone-shaped sprays are dispersion and uniform coverage, but they cannot match rain curtains or other scenes in the scene. Viewers will gradually feel that all the water mist in all scenes is the same, resulting in experience fatigue. This homogenization will cause 4D cinemas to lose their differentiated advantage from ordinary 3D cinemas.
[0004] Therefore, we propose a nozzle for water mist spraying on 4D platform seats to solve the problems mentioned above. Summary of the Invention

[0012] Preferably, both ends of the bearing base plate are fixedly connected to limiting telescopic sleeves, the bottom ends of the two limiting telescopic sleeves are fixedly connected to mounting base plates, the inner walls of the two limiting telescopic sleeves are slidably connected to limiting telescopic rods, the top ends of the two limiting telescopic rods are respectively fixedly installed at the bottom of both ends of the fixing frame, the inner walls of the two limiting telescopic rods are fixedly connected to positioning reinforcing rods, and the outer sides of the two positioning reinforcing rods are provided with support springs. The two ends of the two support springs are respectively fixedly connected to the inner walls of the corresponding limiting telescopic rods and the inner walls of the limiting telescopic sleeves.
[0013] It also includes: a nozzle system for water mist spraying on a 4D platform seat, which includes: an analysis and marking module, a signal capture and processing module, an instruction execution module, a synchronization feedback module, and a dynamic correction module.
[0014] Preferably, the parsing and marking module is used to perform frame-level analysis on the film in advance, mark the trigger points of the water mist effect and insert forward signals; the signal capture and processing module is used to capture forward signals at high speed during playback, extract effective parameters and filter redundant information; the instruction execution module is used to receive pre-processed instructions and drive the nozzle to enter the standby to spray state.

By simultaneously activating two hydraulic cylinders, the height of the spraying assembly is adjusted. The two limiting telescopic rods, limiting telescopic sleeves, and internal support springs limit the spraying assembly. When the hydraulic cylinders fail, the support springs on both sides can effectively prevent the spraying assembly from falling instantly, providing protection for the spraying assembly. When not in operation, the protective baffle can protect the components of the spraying assembly from damage. When the spraying assembly is raised or lowered, the limiting slide rod slides inside the limiting slide groove, keeping the spraying assembly vertical during raising and lowering.
[0018] 3. During use, the parsing and marking module performs frame-level analysis of the film in advance, marks the trigger points of the water mist effect and implants forward signals. The signal capture and processing module analyzes the film stream in real time, detects the "forward synchronization mark" and triggers a response. The instruction execution module receives the pre-processed instructions, selects the position of the target nozzle, and the synchronization feedback module monitors the synchronization deviation between the spray action and the screen in real time. The collected data is used for dynamic correction. The dynamic correction module adjusts the current spray state in real time based on the feedback data and optimizes the future synchronization accuracy through historical data. This allows the audience to have a stronger sense of immersion when watching 3D movies, controls the water flow, and makes the water form accurately match the physical characteristics of the scene and the emotions of the plot, ultimately achieving three-dimensional synchronization of "visual-tactile-emotion".

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] Example 1: Refer to Figures 1-9 As shown, the present invention provides a technical solution: a nozzle for water mist spraying on a 4D platform seat, comprising a spraying assembly 1. The spraying assembly 1 includes a connecting pipe 101, and a plurality of linear nozzles 4, sheet nozzles 5, and mist nozzles 6 are sequentially fixedly connected to the front surface of the connecting pipe 101. The linear nozzle 4 includes a first nozzle 402, and a first solenoid valve 403 is provided on the outside of the first nozzle 402. A first nozzle 404 is fixedly connected to one end of the first nozzle 402, and a plurality of linear water outlet holes 407 are opened on the outer surface of the first nozzle 404. The sheet nozzle 5 includes a second... The first nozzle 502 includes a second nozzle 502. A second solenoid valve 503 is provided on the outside of the second nozzle 502. A second nozzle 504 is fixedly connected to one end of the second nozzle 502. A plate-shaped water outlet hole 507 is formed on the outer surface of the second nozzle 504. The mist nozzle 6 includes a third nozzle 602. A third solenoid valve 603 is provided on the outside of the third nozzle 602. A third nozzle 604 is fixedly connected to one end of the third nozzle 602. A third spray port 605 is formed on the outer surface of the third nozzle 604. A first spray hole 406 is formed at one end of the first nozzle 402. The interior of the first nozzle 404 is... The device includes a first spray nozzle 405, a second nozzle 502 with a second spray hole 506 at one end, a second nozzle 504 with a second spray hole 505 inside, and a third nozzle 602 with a third spray hole 606 at one end. A first spray pipe 401 is threadedly connected to the inner wall of the other end of the first nozzle 402, the second spray pipe 501 is threadedly connected to the inner wall of the other end of the second nozzle 502, and the third spray pipe 601 is threadedly connected to the inner wall of the other end of the third nozzle 602. Each first spray pipe 401, second spray pipe 501, and third spray pipe 601 constitutes a group, and each group sprays... All pipes are inclined outwards. A water supply pipe 102 is fixedly connected to the middle of the inner wall of the connecting pipe 101. Diversion pipes 103 are fixedly connected between the outer surfaces of both sides of the water supply pipe 102 and the inner walls of both sides of the connecting pipe 101. A check valve 104 is installed on the bottom outer surface of the water supply pipe 102. A support component 2 is fixedly connected to the bottom of the connecting pipe 101. The support component 2 includes a fixing frame 201. A controller 7 is installed on the top of the fixing frame 201. The support component 2 is fixedly connected to the bottom of the connecting pipe 101. A lifting component 3 is fixedly connected to the bottom of the protective baffle 204.
[0023] In this embodiment, during use, the water supply pipe 102 is connected to an external water pump, thereby guiding water to the water supply pipe 102 and the diversion pipe 103. Water then enters the connecting pipe 101 through the water supply pipe 102 and the diversion pipe 103. The opening and closing of the check valve 104 enables water spraying and stopping. The first solenoid valve 403, the second solenoid valve 503, and the third solenoid valve 603 are electrically connected to the controller 7, which controls the first solenoid valve 403, the second solenoid valve 503, and the third solenoid valve 603 respectively. The system is activated and deactivated. Linear nozzle 4 sprays multiple linear water streams, while sheet nozzle 5 sprays a sheet-like water curtain, and mist nozzle 6 sprays a water mist. When the movie scene shown in the theater features a waterfall, controller 7 closes the first solenoid valve 403 and the third solenoid valve 603, while simultaneously opening the second solenoid valve 503. This allows water to flow through the second nozzle 501 and the second spray head 502, then exit through the second spray hole 506 and impact the inner wall of the second spray outlet 505. The resulting water mist exits through the sheet-like water outlet. 507 sprays out a sheet-like water curtain. When the movie scene shown in the cinema depicts heavy rain with large raindrops, the controller 7 closes the second solenoid valve 503 and the third solenoid valve 603, while simultaneously opening the first solenoid valve 403. This allows water to flow through the first nozzle 401 and the first spray head 402, then be ejected from the first spray hole 406 and impact the inner wall of the first spray nozzle 405. The resulting water mist is then ejected as linear water droplets from the linear water outlet 407. When the movie scene shown in the cinema depicts morning mist or other water mist, the controller 7 closes the first solenoid valve 403. Valve 403 and the second solenoid valve 503 simultaneously open the third solenoid valve 603, causing the water to flow through the third nozzle 601 and the third nozzle 602 and then be ejected from the third nozzle 606, impacting the inner wall of the third spray port 605. The water mist ejected from the impact is sprayed out from the opening of the third spray port 605, thus realistically simulating scenes such as morning mist, making the audience watching the dynamic film more immersive. Each linear nozzle 4, plate nozzle 5 and mist nozzle 6 is installed at an angle to the outward, so that the sprayed water is directed towards the audience in the back row.
[0024] Example 2: Figures 1-9As shown, a support assembly 2 is fixedly connected to the bottom of the connecting pipe 101. The support assembly 2 includes a fixed frame 201. The bottom end of the water pipe 102 slides through the bottom of the fixed frame 201. Two limiting grooves 202 are opened on the outer surface of the fixed frame 201. Limiting rods 203 are slidably connected to the inner walls of the two limiting grooves 202. A protective baffle 204 is fixedly connected between the two ends of the two limiting rods 203. A controller 7 is set on the top of the fixed frame 201. A lifting assembly 3 is fixedly connected to the bottom of the protective baffle 204. The lifting assembly 3 includes a supporting base plate 301. The front surface of the supporting base plate 301 is fixedly connected to the bottom of the protective baffle 204, and the top surface of the supporting base plate 301 is fixedly connected to the fixed baffle 204. Multiple hydraulic cylinders 302 are installed between the bottom of the fixed frame 201. Both ends of the bearing base plate 301 are fixedly connected to the limiting telescopic sleeves 304. The bottom ends of the two limiting telescopic sleeves 304 are fixedly connected to the mounting base plate 303. The inner walls of the two limiting telescopic sleeves 304 are slidably connected to the limiting telescopic rods 305. The top ends of the two limiting telescopic rods 305 are respectively fixedly installed at the bottom of both ends of the fixed frame 201. The inner walls of the two limiting telescopic rods 305 are fixedly connected to the positioning reinforcing rods 306. The outside of the two positioning reinforcing rods 306 is provided with the support springs 307. The two ends of the two support springs 307 are respectively fixedly connected to the inner walls of the corresponding limiting telescopic rods 305 and the inner walls of the limiting telescopic sleeves 304.
[0025] In this embodiment, during use, the entire spraying device is mounted on the back of the cinema seats using two mounting base plates 303, allowing water mist to be sprayed onto each audience member sitting in the back seats. By simultaneously activating two hydraulic cylinders 302, both cylinders rise simultaneously, thereby moving the fixing frame 201 upwards, and consequently raising the spraying assembly 1. This allows the height of the spraying assembly 1 to be adjusted according to the height of the water flow in the scene. For example, in a scene simulating rain, the spraying assembly 1 needs to be raised, while in a waterfall scene, the water splashing... When the fog is at a lower height, the two limiting telescopic rods 305, the limiting telescopic sleeve 304, and the internal support spring 307 can limit the spray assembly 1. When the hydraulic cylinder 302 fails, the support springs 307 on both sides can effectively prevent the spray assembly 1 from falling instantly, thus protecting the spray assembly 1. When not in operation, the protective baffle 204 can protect the components of the spray assembly 1 and prevent damage to the components. When the spray assembly 1 is raised or lowered, the limiting slide rod 203 slides inside the limiting slide groove 202, which can keep the spray assembly 1 vertical when it is raised or lowered.
[0026] Example 3: Figures 1-9As shown, it also includes: a nozzle system for water mist spraying on a 4D platform seat, which includes: an analysis and marking module 8, a signal capture and processing module 9, an instruction execution module 10, a synchronization feedback module 11, and a dynamic correction module 12. The analysis and marking module 8 is used to perform frame-level analysis on the film in advance, mark the trigger points of the water mist effect, and implant forward signals. The signal capture and processing module 9 is used to capture forward signals at high speed during playback, extract effective parameters, and filter redundant information. The instruction execution module 10 is used to receive pre-processed instructions and drive the nozzles to enter the standby state for spraying. The synchronization feedback module 11 is used to monitor the synchronization deviation between the spraying action and the picture in real time, collect data for dynamic correction, and the dynamic correction module 12 is used to adjust the current spraying state in real time based on the feedback data and optimize the future synchronization accuracy through historical data.
[0027] In this embodiment, during use, the parsing and marking module 8 performs frame-level analysis on the video in advance, marks the water mist effect trigger points, and implants look-ahead signals. First, it identifies scenes requiring water mist, such as "waves crashing," frame by frame, generating a "special effect trigger point timeline." Then, it binds spray parameters to each trigger point. Next, it implants hidden codes such as audio and video 0.3 to 0.5 seconds before the trigger point. The signal capture and processing module 9 parses the video stream in real time, detects the "look-ahead synchronization marker," and triggers a response. The instruction execution module 10 receives the pre-processed instructions, filters out the position of the target nozzle, and converts the parameters into valve-recognizable parameters. Electrical signals put multiple nozzles and valves into standby mode. Based on the time difference between the look-ahead signal and the trigger point, a "full open command" is sent synchronously when the frame arrives to start spraying. The synchronization feedback module 11 monitors the synchronization deviation between the spraying action and the frame in real time, collects data for dynamic correction, and the dynamic correction module 12 adjusts the current spraying state in real time based on the feedback data and optimizes the future synchronization accuracy through historical data. This allows the audience to have a stronger sense of immersion when watching 4D movies, controls the water flow, and makes the water form accurately match the physical characteristics of the scene and the emotions of the plot, ultimately achieving three-dimensional synchronization of "visual-tactile-emotion".
[0028] The device's operation and working principle are as follows: During use, the entire spraying device is mounted on the back of the cinema seats using two mounting base plates 303. This allows water mist to be sprayed onto the audience members sitting in the back seats. Simultaneous activation of two hydraulic cylinders 302 raises them, causing the fixing frame 201 to move upwards, thereby simultaneously lifting the spraying assembly 1. This allows the height of the spraying assembly 1 to be adjusted according to the water flow height in the scene. For example, in a simulated rain scene, the spraying assembly 1 needs to be raised, while in a waterfall scene, the sprayed water mist is lower. In this case, due to the two limiting telescopic rods 305 and the limiting telescopic sleeve 3... 04 and the internal support spring 307 can limit the spray assembly 1. When the hydraulic cylinder 302 fails, the support springs 307 on both sides can effectively prevent the spray assembly 1 from falling instantly, thus protecting the spray assembly 1. When not in operation, the protective baffle 204 can protect the components of the spray assembly 1 and prevent damage to the components. When the spray assembly 1 is raised or lowered, during use, the analysis and marking module 8 performs frame-level analysis of the film in advance, marks the water mist effect trigger points and implants forward signals. First, it identifies scenes that require water mist, such as "waves crashing", frame by frame, generates a "special effect trigger point timeline", then binds spray parameters to each trigger point, and then sprays the water mist effect 0.3 seconds to 0 seconds before the trigger point.Hidden codes such as audio and video are embedded within 5 seconds. The signal capture and processing module 9 analyzes the video stream in real time, detects the "look-ahead synchronization marker," and triggers a response. The instruction execution module 10 receives the pre-processed instructions, selects the target nozzle position, converts the parameters into valve-recognizable electrical signals, and puts multiple nozzles and valves in a standby state. Based on the time difference between the look-ahead signal and the trigger point, a "full open command" is sent synchronously when the frame arrives, initiating spraying. The synchronization feedback module 11 monitors the synchronization deviation between the spraying action and the frame in real time, collecting data for dynamic correction. The dynamic correction module 12 adjusts the current spraying state in real time based on the feedback data and optimizes future synchronization accuracy using historical data. This system enhances the immersive experience for viewers watching 4D movies by controlling water flow to precisely match water patterns with the physical characteristics of the scene and the emotional tone of the plot. In use, the water supply pipe 102 is connected to an external water pump, guiding water to the supply pipe 102 and the branch pipe 103. Water then enters the connecting pipe 101 through the supply pipe 102 and the branch pipe 103. The check valve 104 controls the spraying and stopping of water flow. The first solenoid valve 403, the second solenoid valve 503, and the third solenoid valve 603 are electrically connected to the controller 7, which controls the opening and closing of these valves. The linear nozzle 4 sprays multiple... The water flow is linear, while the sheet nozzle 5 sprays out a sheet-like water curtain, and the mist nozzle 6 sprays out a water mist. When the movie scene shown in the cinema is a waterfall scene, the controller 7 closes the first solenoid valve 403 and the third solenoid valve 603, and simultaneously opens the second solenoid valve 503. This allows the water to flow through the second nozzle 501 and the second nozzle 502, and then be sprayed out through the second nozzle 506, impacting the inner wall of the second spray port 505. The water mist generated by the impact is sprayed out from the sheet-like water outlet 507, forming a sheet-like water curtain. When the movie scene shown in the cinema is a heavy rain scene, with large raindrops, the controller 7 closes the second solenoid valve 503 and the third solenoid valve 603, and simultaneously opens the first solenoid valve 403. This allows the water to flow through the first nozzle 401 and the second nozzle 502, and then be sprayed out through the second nozzle 506, impacting the inner wall of the second spray port 505. 01. After the first nozzle 402, water is ejected from the first nozzle hole 406 and impacts the inner wall of the first spray port 405. The water mist generated by the impact is sprayed out as linear water filaments from the linear water outlet 407. When the scene of the movie being played in the cinema is morning mist or other water mist, the controller 7 closes the first solenoid valve 403 and the second solenoid valve 503, while simultaneously opening the third solenoid valve 603. This allows the water to flow through the third nozzle 601 and the third nozzle 602, and then be ejected from the third nozzle hole 606, impacting the inner wall of the third spray port 605. The water mist generated by the impact is sprayed out from the opening of the third spray port 605. Each linear nozzle 4, plate nozzle 5, and mist nozzle 6 is installed at an angle to the outwards, thus ensuring that the sprayed water is directed towards the audience in the back rows.

The appropriate model is selected according to actual use. Therefore, the control methods and wiring arrangements of the check valve 104, hydraulic cylinder 302, first solenoid valve 403, second solenoid valve 503, third solenoid valve 603, and controller 7 will not be explained in detail.
