Description

Technical Field

[0001] This utility model relates to the field of stage equipment technology, and in particular to a stage smoke machine. Background Technology

[0002] Stage smoke machines play a vital role in modern stage performances, large-scale shows, and various entertainment activities. By generating smoke effects, they enhance the visual atmosphere of the stage, make lighting effects more dazzling, and bring a more stunning visual experience to the audience.

[0003] Traditional stage smoke machines generally have limited smoke output and explosive power, making them less effective on very large stages. A booster fan is typically added to further enhance the explosive power of the smoke emitted from the smoke heater.

[0004] For example, CN205412267 U discloses a stage smoke machine, including a housing and a heater. An oil tank is located at the right end of the housing's inner cavity. The oil tank is connected to an oil pump via a pipe. The oil pump is connected to the heater via a pipe. The heater is connected to a fan via a pipe. A smoke outlet is located at the lower left end of the housing's inner cavity. A support leg is located at the bottom of the housing's outer surface. A lighting lamp is located at the upper left end of the housing's outer surface. A controller is located at the upper middle end of the housing's outer surface. The controller includes an oil pump switch, a heater switch, a fan switch, an ultraviolet lamp switch, and a lighting lamp switch. A support base is located at the middle of the top of the housing's outer surface. A battery is located at the left end of the support base's inner cavity, and a photovoltaic controller is located at the right end of the support base's inner cavity.

[0005] Despite advancements in this technology, the booster fan nozzles are typically open, straight-through structures. If the equipment is placed outdoors and a sudden rainstorm occurs, rainwater can flow from the fan nozzles into the machine, damaging the equipment's electrical system.

[0006] Given the limitations of existing stage fog machines, there is an urgent need for a new technical solution to ensure that existing stage fog machines can provide rain protection while maintaining the fog spraying effect. This is a problem that technicians need to solve. Utility Model Content

The drainage channel communicates with the water collection tray and is used to guide rainwater to the exterior of the machine body.

[0009] Furthermore, the receiving surface of the water receiving tray is provided with a through hole;

[0012] The end of the heater nozzle protrudes from the through hole and is exposed.

[0013] Furthermore, the gap between the through hole and the heater nozzle is sealed with a sealing adhesive.

[0014] Furthermore, the lowest point of the exposed section of the heater nozzle is higher than the receiving surface of the water receiving tray, forming a stepped waterproof structure.

[0015] Furthermore, the central axis of the through hole in the water receiving tray coincides with the rotation axis of the fan.

[0016] Furthermore, the edge of the water receiving tray has an upwardly extending first folded edge structure, which forms a sidewall perpendicular to the receiving surface of the water receiving tray.

[0017] Furthermore, the edge of the first folded structure extends upward and inward toward the inside of the water receiving tray to form a second folded structure.

[0018] Furthermore, the projection of the second folded edge structure covers the rotating outer diameter of the fan.

[0019] Furthermore, the atomizing heating system includes multiple independent oil inlet pipes arranged in parallel to improve the stability of smoke output.

[0020] Furthermore, the heater body is provided with a plurality of heating elements, each heating element corresponding to an oil inlet pipe, and the oil inlet pipe is spirally wound around the outer periphery of the corresponding heating element.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0035] This application addresses the problem that existing stage fog machines cannot provide rain protection while maintaining the desired fog spray effect. It provides a stage fog machine that can both maintain the fog effect and provide good rain protection in outdoor environments.

[0036] The inventor provides a stage fog machine, such as Figures 1 to 5 As shown, the machine body includes an oil supply system 1, a pressure regulation system 2, an injection control system 3, an atomization heating system 4, and a smoke delivery system 5, which are sequentially connected along the fluid transmission direction.

[0037] The oil supply system 1 is used to provide source oil and pressure for the entire stage smoke machine. It includes an oil storage unit 11 for storing oil. The oil storage unit 11 is connected to the input end 131 of the oil pump 13, which provides power for the transmission of smoke oil, through an oil pipeline 12. The output end 132 of the oil pump 13 is connected to the first end 141 of the oil delivery connecting block 14 through another oil pipeline. The oil delivery connecting block 14 is a five-way connecting block with five connection ends. The second end 142 of the oil delivery connecting block 14 is connected to a valve 15. The output end of the valve 15 is connected to a drain return oil pipeline 16. The output end of the drain return oil pipeline 16 is connected to the input end of the oil storage unit 11, thus forming an oil supply system 1 with the functions of pressure storage and providing source oil.

[0038] The pressure regulation system 2 is used to adjust the spray speed of the stage smoke machine. It includes an energy storage device 21 connected to the third end 143 of the oil supply connection block 14 and a pressure sensor 22 connected to the fourth end 144 of the oil supply connection block 14.

[0039] The injection control system 3 includes a valve 31 whose input end 311 is connected to the fifth end 145 of the oil delivery connector 14, and the output end 312 of the valve 31 is connected to a four-way connector 32. In addition, the first output end 321 of the four-way connector 32 is connected to the input end 331 of the valve 33, and the output end 332 of the valve 33 is connected to the oil reservoir 1 via a momentary stop return oil line 34.

[0040] The atomizing heating system 4 includes a heater body 41 and an oil inlet pipe 42. The heater body 41 is a housing, which contains a heating element 412. A heater nozzle 411 is located outside the housing, and the heater nozzle 411 connects the interior of the heater body 41 to the outside.

[0041] The input end 421 of the oil inlet pipe 42 is connected to the four-way connector 32, and the output end 422 of the oil inlet pipe 42 is connected to the heater nozzle 411 to deliver the e-liquid obtained from the four-way connector 32 to the heater nozzle 411.

[0042] The smoke delivery system 5 includes a spray nozzle 51, which is equipped with a fan 52. The spray nozzle 51 is located on the machine body so that the interior of the machine body is connected to the outside.

[0043] Specifically, the machine body also has a waterproof drainage system 6; the waterproof drainage system 6 includes a water receiving tray 61 and a drainage channel 62; the water receiving tray 61 is located below the spray nozzle 51 and is used to collect rainwater flowing into the spray nozzle 51; the drainage channel 62 is connected to the water receiving tray 61 and is used to guide rainwater to the outside of the machine body.

[0044] In summary, when this stage fog machine is working, as... Figures 4 to 5 As shown, proceed according to the following steps:

[0045] The first step is purging. Specifically, the oil pump 13 and valve 15 are opened sequentially, and valve 31 is closed, so that the oil pump 13 can draw e-liquid from the oil storage unit 11. The e-liquid then passes through the oil supply pipeline 12, the oil supply connection block 14, the valve 15, and the purging return oil pipeline 16 to form a loop, thus purging the air from the oil supply system 1. This process lays the foundation for the subsequent spray requirements and is a necessary process for system pressurization.

[0046] Next, continue to operate the oil pump 13, but close valves 15, 31, and 33. This is to ensure that after the oil pump 13 draws e-liquid from the oil reservoir 11, it passes sequentially through the oil delivery pipeline 2 and the oil delivery connector 14. The accumulator 21 is connected to the oil delivery connector 14 to obtain the e-liquid pressure passing through the connector 14. Under the action of the oil pump 13, e-liquid is continuously forced into the oil delivery connector 14, and the pressure in the accumulator 21 continuously increases until it reaches the required spray pressure value. Meanwhile, the pressure sensor 22 connected to the oil delivery connector 14 continuously displays the pressure value in the accumulator 21, ensuring consistent pressure for the user to adjust the spray speed. Specifically, when the pressure sensor 22 detects that the pressure has reached the set value, the next spray operation is executed.

[0047] Next, turn on the oil pump 13, close valves 15 and 33, and then open valve 31 to connect the oil reservoir 11 to the four-way connector 32. This allows the e-liquid in the oil reservoir 11 to flow into the four-way connector 32. Under the action of the four-way connector 32, the e-liquid flows into the atomizing heating system 4.

[0048] Specifically, the e-liquid flows into the oil inlet pipe 42 after passing through the four-way connector 32. Since the oil inlet pipe 42 is arranged to spiral upward around the heating element 412, the e-liquid is heated and vaporized into smoke, which is then sprayed out from the heater nozzle 411.

[0049] After the spraying is completed, valve 31 and the oil pump 13 are closed, and valve 33 is opened. At this time, the oil pressure in the heater body 41 is released, and the oil pump 13 is closed, so there is no power for the e-liquid to continue entering. Therefore, the vapor column sprayed from the heater nozzle 411 stops instantly. At this time, the remaining e-liquid in the oil inlet pipe 42 returns to the oil storage unit 1 through the four-way connector 32, the valve 33, and the instantaneous stop return oil pipe 34.

[0050] Finally, once the smoke is ejected from the heater nozzle 411, the fan 52 quickly draws in the smoke and pushes it a long distance through the spray nozzle 51, forming a powerful column of smoke.

[0051] When it rains, rainwater flows into the machine body through the spray nozzle 51. Since the water receiving tray 61 is located below the spray nozzle 51, it can effectively collect the rainwater and allow it to flow away to the outside of the machine body.

[0052] In detail, rainwater falling from the spray nozzle 51, upon contact with the receiving surface 611, is continuously drawn into the drainage channel 62. It should be understood that the receiving surface 611 should have at least one drain outlet 6111, which connects to the drainage channel 62, allowing rainwater to flow from the drain outlet 6111 into the drainage channel 62 and, guided by the drainage channel 62, flow to the outside of the machine body.

[0053] In summary, the stage fog machine of this technical solution utilizes a waterproof drainage system 6. This system collects rainwater by placing a water collection tray 61 below the spray nozzle 51 and guides the water to the outside of the machine through a drainage channel 62. This effectively solves the problems of rainwater intrusion into the machine during outdoor use of existing fog machines, leading to short circuits, oil contamination, and component corrosion. Based on gravity drainage and physical isolation, it achieves reliable waterproofing without additional power, improving the stability and lifespan of the fog machine in humid environments. Furthermore, its simple structure and low cost make it suitable for complex scenarios such as outdoor performances.

[0054] In one embodiment of the present invention, the receiving surface of the water receiving tray 61 is provided with a through hole 612; the atomizing heating system includes a heater body 41; the heater body 41 has a heater nozzle 411 at one end facing the water receiving tray 61; the end of the heater nozzle 411 protrudes from the through hole 612 and is exposed.

[0055] This embodiment uses a through hole 612 in the water receiving tray 61 to allow the heater nozzle 411 to protrude and be exposed. The protruding structure of the heater nozzle 411 is used to assemble and fix the water receiving tray 61, ensuring normal spraying of atomized smoke, intercepting rainwater, and effectively shielding the heater body 41 to prevent rainwater from falling into the heater body 41 and causing the heating element 412 to rust. This structure is simple and highly reliable, suitable for complex outdoor environments.

[0056] Furthermore, to prevent water intrusion caused by the gap at the connection between the heater nozzle 411 and the through hole 612, the gap at the connection between the through hole 612 and the heater nozzle 411 is sealed with a sealing adhesive F (such as high-temperature resistant silicone). This seals the gap, preventing rainwater from entering the interior of the heater body 41 through the gap.

[0057] In one embodiment of this invention, the lowest point D of the exposed section of the heater nozzle 411 is higher than the receiving surface 611 of the water receiving tray. Gravity is used to prevent rainwater from flowing back along the nozzle surface, forming a stepped waterproof structure. This prevents rainwater from flowing back along the surface of the heater nozzle 411 and seeping into the interior of the heater body 41 if the heater nozzle 411 is flush with or too low to the water receiving tray 61, which could cause short circuits or component corrosion.

[0058] Therefore, by placing the lowest point D of the exposed section of the heater nozzle 411 higher than the receiving surface 611 of the water tray, a stepped waterproof structure is formed using the height difference to create a physical barrier. This allows rainwater to drip naturally onto the water tray 61, preventing it from flowing back along the heater nozzle 411. This, combined with the rainwater collected by the water tray 61 being discharged through the drainage channel 62, forms a double waterproof protection, effectively solving the problem of rainwater backflowing along the heater nozzle 411. This design is simple in structure, highly protective, and significantly improves safety for outdoor use.

[0059] In one embodiment of this utility model, such as Figure 4 As shown, the central axis A1 of the through hole 612 of the water receiving tray 61 coincides with the fan rotation axis A2.

[0060] This technical solution ensures that the direction of smoke injection is completely consistent with the direction of fan airflow by aligning the central axis A1 of the through hole in the water collection tray 61 with the fan rotation axis A2. This avoids problems such as uneven smoke diffusion, reduced injection efficiency, and condensate backflow caused by axial misalignment. The principle is to optimize the airflow path using a coaxial structure, allowing the atomized smoke to be directly axially propelled by the fan airflow, reducing turbulence interference. Simultaneously, aligning the through hole 612 of the water collection tray 61 with the fan rotation center prevents rainwater or condensate from accumulating and leaking at off-center locations. This design further enhances the reliability of the waterproof system and makes the overall structure more compact and efficient.

[0061] In one embodiment of the present invention, the edge of the water receiving tray 61 has an upwardly extending first folded edge structure 613, and the first folded edge structure 613 forms a sidewall perpendicular to the receiving surface 611 of the water receiving tray 61.

[0062] This embodiment utilizes an upwardly extending first folded edge structure 613 at the edge of the water receiving tray 61 to form a sidewall perpendicular to the receiving surface 611. This folded edge structure creates a physical barrier, preventing collected rainwater from splashing outwards due to equipment vibration or airflow disturbances. Simultaneously, it guides the water flow along the receiving surface to the drainage channel, preventing leakage into the machine's interior. This effectively solves the waterproofing failure problem caused by rainwater splashing or overflowing in traditional water receiving trays. It effectively improves the splash-proof capability of the water receiving tray, ensures directional rainwater discharge, and enhances the stability and reliability of the waterproofing system.

[0063] In one embodiment of the present invention, the edge of the first folded edge structure 613 extends upward and inclined toward the inside of the water receiving tray 61 to form a second folded edge structure 614.

[0064] The technical solution constructs a double splash barrier by designing the edge of the first folded edge structure 613 of the water receiving tray 61 to extend upward and inward to form a second folded edge structure 614. The inwardly angled second folded edge structure 614 forms a guiding surface, guiding splashing water droplets back into the water receiving tray upon impact with the folded edge. This effectively solves the problem of rainwater splashing and overflowing that may still occur with traditional single-layer folded edges during strong airflow or equipment vibration. This design further improves the reliability of splash protection, ensuring that splashing water is effectively intercepted.

[0065] In one embodiment of this invention, the projection of the second folded edge structure 614 covers the outer diameter of the fan's rotation, which is the maximum rotation diameter of the fan blade tip. This design, utilizing the extended coverage of the second folded edge structure 614, forms a complete annular protective zone on the vertical projection surface of the fan's rotation plane. This ensures that any water droplets ejected by the fan 52 are effectively intercepted by the second folded edge structure 614. This design constructs an all-around splash protection system, completely solving the technical problem that a high-speed rotating fan might eject rainwater beyond the water tray's range, thus ensuring the reliable operation of the stage fog machine under extreme weather conditions such as heavy rain.

[0066] Furthermore, in one embodiment, such as Figure 4 As shown, the atomizing heating system 4 includes multiple independent oil inlet pipes 42 arranged in parallel to improve the stability of vapor output. Furthermore, the heater body 41 is provided with multiple heating elements 412, each heating element 412 corresponding to one oil inlet pipe 42, and the oil inlet pipe 42 is spirally wound around the outer periphery of the corresponding heating element 412.

[0067] This design achieves redundant oil supply through parallel pipelines, ensuring that a single path failure does not affect overall operation. The spiral winding structure allows for ample heat exchange between the oil circuit and the heating element, improving atomization efficiency while ensuring uniform heating of each pipeline. It effectively solves the technical problems of uneven oil supply and fluctuating heating efficiency leading to unstable smoke output or insufficient smoke volume in existing single-pipeline designs. It is particularly suitable for applications requiring stringent smoke effects, such as large-scale stage performances.

[0068] In summary, compared with existing smoke machines, the stage smoke machine of this technical solution can provide rain protection while maintaining the smoke spraying effect.
