Description

Technical Field

[0001] This application relates to the field of bubble blowing, and more particularly to a smoke collection box and a smoke snow machine. Background Technology

[0002] A snow machine is a device used to create artificial snowflakes, typically for stage performances, weddings, or creating atmosphere during outdoor filming. Existing snow machines usually use snow oil to produce foam-like simulated snowflakes, resulting in a limited range of effects. Furthermore, foam-like snowflakes require high pressure to produce, leading to a generally high level of noise in existing snow machines.

[0003] A smoke bubble machine is a device that can simultaneously produce smoke, bubbles enveloping the smoke, and bubbles enveloping the air, creating different visual effects. It is widely used in stage performances, weddings, and outdoor filming to create atmosphere. Smoke bubble machines typically generate smoke by heating e-liquid, thus producing no noise during operation. Therefore, combining the advantages of snow machines and traditional smoke bubble machines, this application proposes a smoke snow machine that simulates the visual effect of snowflakes while operating on the same principle as a smoke bubble machine. Summary of the Invention

[0004] This application provides a smoke / snow machine. The smoke / snow machine includes at least one film-forming nozzle, a liquid delivery assembly, a gas delivery assembly, and a brush body. The film-forming nozzle has a liquid inlet pipe and a gas channel, the diameter of which is less than or equal to 10 mm. The liquid delivery assembly is connected to and communicates with the liquid inlet pipe for delivering bubble solution to the liquid inlet pipe. The gas delivery assembly is connected to and communicates with the gas channel for delivering smoke to the gas channel. The brush body is disposed adjacent to the at least one film-forming nozzle and is rotatable relative to the film-forming nozzle. The brush body is provided with at least one brush rod, which rotates through the liquid inlet pipe and the gas channel when the brush body rotates.

[0005] The infusion component delivers bubble solution to the inlet pipe during operation, while the gas delivery component delivers smoke to the gas channel. The bubble solution flowing from the inlet pipe and the smoke flowing from the gas channel are then brushed together by a brush rod to form smoke bubbles. Because the diameter of the gas channel is less than or equal to 10 mm, the resulting smoke bubbles are small, creating a visually simulated snowflake effect. Alternatively, the infusion component can be disabled, in which case the smoke snow machine can directly deliver smoke. Or, the gas delivery component can also be disabled, in which case the smoke snow machine can be used as a traditional bubble machine. Compared to existing snow machines, the smoke snow machine of this application can produce a rich variety of visual effects, including smoke, bubbles, large simulated snowflakes, and small simulated snowflakes. Furthermore, the smoke snow machine of this application operates without noise, improving the user experience. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0019] like Figure 1-12As shown, this application provides a smoke and snow machine 100, which combines the effects of existing smoke and bubble machines and smoke and snow machines. It can be used to generate bubbles, smoke, and smoke bubbles, and can be used in stage performances, weddings, celebrations and other occasions to create certain visual effects.

[0020] Specifically, the smoke / snow machine 100 includes at least one film-forming nozzle 30, a liquid delivery assembly, a gas delivery assembly, and a brush body 40. The film-forming nozzle 30 has a film-forming space 32, a liquid inlet pipe 34, and a gas channel 33. The liquid inlet pipe 34 and the gas channel 33 communicate with the film-forming space 32, and the diameter of the gas channel 33 is less than or equal to 10 mm. The liquid delivery assembly is connected to and communicates with the liquid inlet pipe 34 for delivering bubble solution to the liquid inlet pipe 34. The gas delivery assembly is connected to and communicates with the air inlet for delivering smoke to the gas channel 33. The brush body 40 is disposed adjacent to at least one film-forming nozzle and is rotatable relative to the film-forming nozzle. The brush body 40 is provided with at least one brush rod 41. When the brush body 40 rotates, the brush rod 41 passes through the film-forming space 32 at a predetermined frequency, causing a layer of bubble film to form on the surface of the film-forming space 32.

[0021] When in operation, the infusion assembly delivers bubble solution to the inlet pipe 34, while the gas delivery assembly delivers smoke to the gas channel 33. The bubble solution flowing from the inlet pipe 34 and the smoke flowing from the gas channel 33 then converge in the film-forming space 32 to form smoke bubbles. Because the diameter of the gas channel is less than or equal to 10 millimeters, the resulting smoke bubbles are small, creating a visually simulated snowflake effect.

[0022] In one embodiment, the infusion component may also be disabled, in which case the smoke and snow machine 100 can directly deliver smoke. Alternatively, the gas delivery component may also be disabled, in which case the smoke and snow machine 100 can be used as a traditional bubble machine. Compared with existing smoke and snow machines 100, the smoke and snow machine 100 of this application can produce rich visual effects such as smoke, bubbles, large simulated snowflakes, and small simulated snowflakes. At the same time, the smoke and snow machine 100 of this application does not generate noise during operation, thus improving the user experience.

[0023] In one embodiment, the film-forming nozzle may not have a film-forming space 32. The brush rod 41 can directly pass through the liquid inlet pipe 34 to form a bubble film. Under the action of air pressure, the gas flowing out from the gas channel can also be wrapped by the bubble film to form smoke bubbles.

[0024] It should be noted that the preferred diameter of the gas channel is between 3 mm and 7 mm, resulting in smaller smoke bubbles that easily create a visual snowflake effect. If the gas channel diameter is less than 3 mm, the corresponding film-forming space is also small, making it difficult for bubbles to form on the surface of the film-forming space. The smoke will simply escape from the gas channel, failing to simulate a snowflake effect and negating the bubble machine function of the smoke snow machine 100. If the gas channel diameter is greater than 10 mm, the resulting smoke bubbles are larger, making the effect visually recognizable to the user, but failing to simulate the visual effect of snowflakes. A gas channel diameter between 3 mm and 10 mm produces smoke bubbles of a more suitable size for simulating a snowflake effect.

[0025] In one embodiment, the number of film-forming nozzles 30 is at least two. The number of film-forming nozzles 30 affects the scale of snowflakes formed by the smoke snowflake machine. When there is only one film-forming nozzle 30, fewer smoke bubbles are generated per unit time, making it impossible to generate a large-scale snowflake visual effect. On the other hand, if the number of film-forming nozzles is too large, the required connecting accessories also increase, which is not conducive to the miniaturization design of the smoke snowflake machine. Therefore, in this embodiment, the number of film-forming nozzles is preferably two, which ensures both the generation speed of simulated snowflakes and the miniaturization design of the smoke snowflake machine.

[0026] In one embodiment, the gas channel 33 is uniformly provided with arc-shaped teeth 331 on its peripheral wall. The smoke contains a small amount of dust particles. When the smoke flows through the gas channel 33, the arc-shaped teeth 331 can absorb some of the dust, making the resulting snowflake-like smoke bubbles lighter.

[0027] The gas delivery assembly includes an air inlet pipe 66, a multi-channel pipe 65, and a smoke collection box 63. The air inlet pipe 66 is fitted inside the film-forming nozzle 30 and is connected to the gas passage 33. The multi-channel pipe 65 includes a main channel 651 and a branch channel 652 connected to the main channel 651. The first end of the main channel 651 is connected to the outlet 632 of the smoke collection box 63, and the second end of the main channel 651 is connected to the first end of the branch channel 652. The second end of each branch channel 652 is fitted and connected to the corresponding air inlet pipe 66. The smoke flowing out of the smoke collection box 63 can flow sequentially through the main channel 651 and the branch channel 652 and flow into the air inlet pipe 66 under the guidance of the branch channel 652.

[0028] In one embodiment, a return pipe 653 extends downward from the bottom of each branch channel 652. The return pipe 653 is located near the second end of the branch channel 652 and is connected to the smoke collection box 63. Some smoke condenses during its flow, forming condensed e-liquid. The return pipe 653 guides the condensed e-liquid back to the smoke collection box 63. This design prevents condensed e-liquid from accumulating in the film-forming nozzle 30 or the air inlet pipe 66. Therefore, the smoke can always smoothly reach the film-forming space 32, ensuring the normal operation of the smoke frosting machine 100.

[0029] In one embodiment, the gas delivery assembly further includes a multi-port connector 69 and a connecting pipe 68. The multi-port connector 69 includes a first connector 691 and a second connector 692 communicating with the first connector 691. The first connector 691 is connected and communicates with the vapor collection box 63. The second connector 692 is connected and communicates with the return pipe 653 via the connecting pipe 68. Vertically, the multi-port connector 69 is positioned below the return pipe 653; therefore, e-liquid flowing from the return pipe 653 will flow towards the multi-port connector 69 under gravity.

[0030] It should be noted that the number of second connectors 692 and branch channels 652 in the multi-way connector 69 is the same as the number of film-forming nozzles 30. For example, when two film-forming nozzles 30 are provided, the multi-way pipe 65 includes two branch channels 652, and the multi-way pipe 65 is Y-shaped overall. Similarly, the multi-way connector 69 is a tee connector including two second connectors 692, and the tee connector is also Y-shaped overall. For example, as... Figure 11 As shown, when there is only one film-forming nozzle 30, the multi-way pipe 65 can be a linear pipe. In this case, the return pipe 653 can be directly connected to the smoke collection box 63 through the connecting pipe 68 or through a linear two-way connector. For example, when there are three film-forming nozzles 30, the multi-way pipe 65 is a four-way pipe with three branches 652, and the multi-way connector 69 is a four-way connector. Of course, as mentioned earlier, having more than three film-forming nozzles 30 would hinder the miniaturization design of the smoke and snow machine 100, and therefore will not be listed further.

[0031] In one embodiment, the return pipe 653 has a return port 654, which is disposed on the bottom wall of the branch 652 and inclined relative to the bottom wall of the branch 652. Condensed e-liquid can flow into the return pipe 653 through the return port 654 under the influence of gravity. The arrangement of the return port 654 allows condensed e-liquid in the multi-port pipe 65 to flow naturally to the return pipe 653.

[0032] In one embodiment, the gas delivery assembly further includes an oil pump 61, an oil reservoir 60, a heater 62, and a smoke collection box 63. The oil reservoir 60 stores e-liquid. The oil pump 61 draws e-liquid from the oil reservoir 60 and delivers it to the heater 62. The heater 62 heats the e-liquid, causing it to atomize and produce smoke. The smoke collection box 63 collects the smoke. After exiting the smoke collection box 63, the smoke reaches the location where a bubble film forms. As the bubble film gradually forms bubbles under the influence of air pressure difference, smoke flows into the bubbles, filling them with smoke. Optionally, the oil pump 61 and its corresponding inlet pipe are connected between the oil reservoir 60 and the heater 62. In other embodiments, the oil pump 61 may be omitted, and by limiting the height relationship between the oil reservoir 60 and the heater 62, the oil reservoir 60 may flow directly to the heater 62 under gravity.

[0033] The smoke collection box 63 is provided with an inlet 631 and an outlet 632. The inlet 633 and outlet 634 are also present. The inlet 631 is connected to the heater 62 to receive the smoke generated by heating the e-liquid. The outlet 632 is connected to a multi-port pipe 65, allowing smoke flowing in from the inlet 631 of the smoke collection box 63 to flow out through the outlet 632. Vertically, the outlet 634 is located at the lowest point of the smoke collection box 63 and is connected to the e-liquid storage bottle 60. Because the outlet 634 is at the lowest point, both condensed e-liquid formed inside the smoke box and condensed e-liquid flowing in from the inlet 633 can flow to the outlet 634 under the influence of gravity. The connection between the outlet 634 and the storage bottle 60 allows the condensed e-liquid to be reused.

[0034] In one embodiment, the gas delivery assembly further includes a first airflow drive 64, which is connected between the multi-channel pipe 65 and the smoke collection box 63. The first airflow drive 64 is used to draw smoke from the smoke collection box 63 and drive the smoke to the location where the bubble film forms. Specifically, the first airflow drive 64 can be a first fan. The first fan connects the smoke collection box 63 and the multi-channel pipe 65. The branches 652 of the multi-channel pipe 65 are respectively connected to the corresponding air inlet pipes 66. Each air inlet pipe 66 is connected to the corresponding film-forming nozzle 30 and communicates with the gas channel 33. Therefore, the smoke drawn out by the first fan can quickly flow into the main channel 651, and through the diversion effect of the branch pipes 652, flow into the air inlet pipes 66 and finally into the gas channel 33 of the film-forming nozzle 30. Since the gas channel communicates with the film-forming space 32, the smoke can meet the bubble film formed at the port of the film-forming space 32 and be wrapped by the bubble film under the pressure difference to form small-sized smoke bubbles, thereby simulating the visual effect of snowflakes.

[0035] In one embodiment, the infusion assembly includes a storage tank 50, an infusion tube 53, and a pump 52. The storage tank 50 stores bubble solution, and the pump 52 is connected to both the storage tank 50 and the infusion tube 53. The infusion tube 53 is connected to an inlet tube 34, and the pump 52 delivers the bubble solution to the infusion tube 53. Driven by the pumping force, the bubble solution entering the infusion tube 53 flows further to the inlet tube and then to the film-forming space 32. Thereafter, the bubble solution contacts the brush rod 41 and forms a bubble film at the port of the film-forming space 32. In this embodiment, due to the action of the pump 52, the bubble solution flowing to the inlet tube 34 still carries a certain impact force. To prevent the bubble solution from forming a water column that directly sprays out of the film-forming space 32, film-forming teeth 31 are provided on the peripheral wall of the film-forming space 32, partially blocking the inlet tube 34. In this way, the film-forming teeth 31 not only counteract the impact force of the bubble solution but also reduce the flow rate of the bubble solution, which is more conducive to the formation of the bubble film.

[0036] In one embodiment, the smoke and snow machine 100 further includes a second airflow drive 65 for generating an airflow that directs the generated bubbles away from the smoke and snow machine 100, preventing bubbles from accumulating and colliding near the machine. In some embodiments, the second airflow drive 65 is a second fan. The smoke and snow machine 100 also includes an airflow duct 651 connected to the second airflow drive 65. The airflow duct 651 is used to regulate the direction of the airflow generated by the second airflow drive 65.

[0037] In one embodiment, the vaporizer 100 includes a housing. The housing includes a first mounting shell 10 and a second mounting shell 20, which together form a mounting cavity. A reservoir 60 in the vapor delivery assembly is partially installed within the mounting cavity. For example, the body of the reservoir 60 is installed within the mounting cavity, while the cap of the reservoir 60 is exposed outside the mounting cavity. Therefore, when refilling e-liquid, the user does not need to disassemble the vaporizer 100; they can simply unscrew the cap to add e-liquid. Operation is very convenient. All other components of the vapor delivery assembly, except for the reservoir 60, are completely installed within the mounting cavity. Similarly, a liquid tank 50 is partially installed within the mounting cavity, with its upper part open and partially exposed outside the mounting cavity. Therefore, when refilling bubble liquid, the user can directly pour it into the upper opening of the liquid tank 50, making operation very quick and convenient.

[0038] Furthermore, since bubble solution is relatively inexpensive, to prevent residual bubble solution from flowing out of the storage tank 50 into the mounting cavity due to improper placement of the smoke and snow machine 100 after use, in one embodiment, the storage tank 50 is provided with a first drain port 51 at its bottom, and the second mounting shell 20 is provided with a second drain port corresponding to the first drain port 51 and a sealing plug 21 movably connected to the second mounting shell 20. After installation, the body of the storage tank 50 abuts against the inner wall of the second mounting shell 20. During use, the sealing plug 21 blocks the first drain port 51 and the second drain port, allowing the storage tank 50 to store the bubble solution. After the smoke and snow machine 100 is used up, the user can remove the sealing plug 21 from the first drain port 51 and the second drain port to easily drain the bubble solution.

[0039] In one embodiment, the first mounting housing 10 includes a mounting panel 11, with the film-forming nozzle 30 and the brush body 40 both mounted on the outer wall of the mounting panel 11. Specifically, the film-forming nozzle 30 is integrally formed with the mounting panel 11. The brush body 40 is detachably connected to the mounting panel 11. Users can replace the brush body 40 with different numbers of brush rods 41 as needed; therefore, the smoke and snow machine 100 of this application can create very rich snowflake visual effects. For example, when a dense snowflake effect is required, a method such as... Figure 12 The brush body 40 shown has three brush rods 41. However, if only a sparse snowflake effect is desired, a brush body 40 can be used as shown in the diagram. Figure 11 The diagram shows a brush body 40 with a single brush rod 41. It should be noted that when the number of brush rods 41 exceeds one, the brush rods 41 are arranged at equal angles around the rotation center of the brush body 40. This arrangement ensures that the time interval between the generation of two bubble films by each film-forming spray is constant.

[0040] Furthermore, the density and color depth of the snowflakes can be adjusted by regulating the rotation frequency of the brush body 40. Specifically, the smoke and snow machine 100 also includes a drive mechanism and a housing 13. The housing 13 encapsulates the drive mechanism on the inner wall of the mounting panel 11, preventing the drive structure from being exposed and thus extending the service life of the drive mechanism. The drive mechanism includes a gear set 112 and a motor 111. The gear set 112 and the motor 111 are connected to the brush body 40 for transmission. The motor 111 can be a fixed-frequency motor. In this case, the output frequency of the motor 111 is fixed, and the brush rods 41 of the brush body 40 pass through the film-forming space 32 at a fixed frequency. Therefore, the more brush rods 41 there are, the faster the bubble film is formed in the same film-forming space 32, the less smoke is wrapped in the bubble film, and the denser and lighter the snowflakes are formed. Conversely, the fewer brush rods 41 there are, the fewer bubble films are formed, resulting in a sparser and darker snowflake effect.

[0041] Of course, the motor 111 can also be a variable frequency motor 111. In this case, the brush body 40 can rotate at different frequencies. That is, with a fixed number of brush rods 41 on the brush body 40, different snowflake visual effects can be created by adjusting the frequency of the motor 111. In the smoke and snow machine 100 of this application, the motor 111 is preferably a variable frequency motor 111. Based on this, by superimposing brush bodies 40 with different numbers of brush rods 41, the smoke and snow machine 100 of this application can create a very rich variety of snowflake visual effects.

[0042] In one embodiment, the smoke and snow machine 100 further includes a controller (not shown) and buttons 12. The controller is electrically connected to the buttons 12, the drive mechanism, the gas delivery assembly, and the liquid delivery assembly. The controller is used to control the motor speed and the operating state of the smoke and snow machine 100. Users can switch between different operating states of the smoke and snow machine 100 by controlling the buttons 12. For example, by pressing different buttons 12, the smoke and snow machine 100 can output only smoke, only normal bubbles, or different snowflake effects, thus making the smoke and snow machine 100 suitable for more application scenarios.

[0043] In one embodiment, the smoke and snow machine 100 further includes a cooling fan 70, which is installed in the mounting cavity for internal heat dissipation of the smoke and snow machine.

[0044] The above description is merely a preferred embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, or improvements made within the technical scope of this disclosure should be included within the scope of protection of this disclosure.
