Description

Technical Field

[0001] The utility model relates to the technical field of fog machines, in particular to a handheld thin fog system. Background Technique

[0002] Stage fog machines generally use organic solvents with a relatively large water content, such as glycerin. Through a high-pressure oil pump, it is injected into a thin-caliber heating tube. Under the high-temperature action of the heating tube, water is converted into steam pressure, which increases the temperature and pressure of the fog oil mixture in the heating tube. Then, through the thin-caliber heating tube, the high-temperature and high-pressure fog oil mixture is sprayed into the atmosphere for rapid pressure reduction to form fog. White aerosol fog is formed to achieve a certain stage beauty effect. In some entertainment venues, such as various theaters, large studios, mobile performances, cultural groups, fashion shows, exhibitions, conference performances, etc., it is often necessary to create a foggy stage effect. The fog machine can make consumables such as atomizing agents (generally fog oil) into a fog state to improve the performance effect of the stage.

[0003] For traditional fog machines, they generally need to be placed on a tabletop or on the ground. Due to the limitation of the atomization principle, they are relatively large in size. The atomization principle adopted has low thermal efficiency and low atomization efficiency, and requires a relatively large power of electricity to drive (generally above 400W, not less than 100W), so they need to be plugged in to work. At the same time, because the fog is atomized by rapidly reducing the pressure of the high-pressure atomizing agent, during the process, after the high-pressure aerosol is sprayed into the atmosphere, the pressure drops suddenly, the volume expands rapidly, and a large amount of heat is absorbed. Due to the very rapid physical change process, it further accelerates the degradation of the atomizing agent aerosol particles, so its maintenance time is extremely short. When using it to maintain the fog, the fog machine needs to run for a long time.

[0004] In the field of stage beauty, an important application of fog is "stage thin fog", a kind of thin aerosol similar to artificially created haze. When there is thin fog in the space, the lighting effect can produce the "Tyndall effect", so that the light has a more abundant scattering and beam effect, so it is widely used in the field of stage beauty. Because the fog generated by traditional stage fog machines has a very short maintenance time, when used as a fog source for environmental thin fog, it needs to be sprayed for a long time to maintain the low-density thin fog in the environment.

[0005] In the field of film and television creation, "haze" is often used, generally referred to as "film and television haze" or "density". During the film and television shooting process, lights are needed to create the picture atmosphere, outline the characters and the environment, etc. However, under high-resolution professional filming equipment, the contrast between light and dark in the picture is relatively strong and the sharpness is high. Therefore, in traditional film and television creation, ways such as adding soft light covers to lights and adding filters to lenses are needed to adjust or reduce the sharpness. Another important way is to use "film and television haze". After filling the shooting space with thin aerosol, it reduces the light transmittance of the overall space, and at the same time can combine with the lights to form the "Tyndall effect", thus filtering out a lot of ambient stray light in the picture captured by the lens, amplifying the lighting effect and highlighting the main body, while achieving the effect of softening the picture.

[0006] However, due to the different work processes of film and television creation, unlike stage scenes in a fixed scene, it is often necessary to frequently move to different environments for shooting and creation. The power supply required by the stage smoke machine often cannot be satisfied in the shooting scene. Moreover, for the power cord required by the power supply, in order to avoid revealing the secret, it needs to be hidden additionally. Therefore, traditional stage smoke machines are difficult to adapt to film and television shooting scenes. Therefore, in the field of film and television creation, "smoke cakes" are generally used to produce smoke. It is a prefabricated combustible made by mixing ammonium chloride, potassium chlorate, rosin, and resin and pressing them into a round cake shape. A large amount of smoke can be generated through combustion. However, in this solution, because the combustion process cannot be controlled and the smell is pungent, there has been no better alternative for a long time.

[0007] In recent years, a portable smoke machine (also called a handheld smoke machine) product has emerged. Because of its advantages such as small size, portability, good control, no delay, easy operation, and battery power supply, it is deeply loved by film and television practitioners. It uses a concentrated organic solvent as the atomizing agent. Instead of using water as a pressurizing agent for pressurization and heating, it generates smoke by directly heating the concentrated atomizing agent and then quickly cooling it. The entire atomization process occurs smoothly. Therefore, its smoke has characteristics such as higher concentration, stronger stability, and long maintenance time. However, because its own output smoke flow rate is low, it can only output high-concentration smoke and has insufficient diffusibility. When making low-density aerosol, it needs to wait for the natural air flow in the environment to diffuse, and the preparation time is relatively long.

[0008] However, in the existing technology, in the usage of "film and television haze" by adding a fan to a handheld smoke machine, the scheme of accelerating the ejection after suction by the fan has disadvantages in terms of usage experience and convenience: The smoke enters and is inhaled directly into the fan through the air intake side of the fan, and is accelerated and ejected by the fan. After long-term use, the condensed oil accompanying the smoke aerosol will accumulate on the fan blades and the surface of the air flow channel, which is difficult to clean. At the same time, the oozing liquid is prone to cause secondary pollution, and after adsorbing dust, it will affect the fan efficiency. When the accumulated liquid enters the fan, it is easy to cause corrosion of the circuit board and further damage the equipment. Utility Model Content

[0067] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification.

[0068] It should be noted that the structures, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those skilled in the art to understand and read, and are not used to limit the limited conditions for the implementation of the present utility model. Therefore, they do not have technical essential significance. Any modification of the structure, change of the proportional relationship, or adjustment of the size, without affecting the effects that the present utility model can produce and the purposes that can be achieved, should still fall within the scope covered by the technical content disclosed in the present utility model.

The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope for the implementation of the present utility model.

[0069] For the convenience of description, as Figure 11As shown, the dimension of the portable smoke machine 3 along the X-axis direction is defined as the length of the portable smoke machine 3, the dimension of the portable smoke machine 3 along the Y-axis direction is defined as the width of the portable smoke machine 3, and the dimension of the portable smoke machine 3 along the Z-axis direction is defined as the height of the portable smoke machine 3; the side of the portable smoke machine 3 facing the positive direction of the X-axis is defined as the positive side, and the side of the portable smoke machine 3 facing the negative direction of the X-axis is defined as the back side; the side of the portable smoke machine 3 facing the positive direction of the Y-axis is defined as the left side, and the side of the portable smoke machine 3 facing the negative direction of the Y-axis is defined as the right side; the side of the portable smoke machine 3 facing the positive direction of the Z-axis is defined as the top side, and the side of the portable smoke machine 3 facing the negative direction of the Z-axis is defined as the bottom side.

[0070] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, the utility model provides a handheld thin cigarette system, comprising:

[0071] Portable fog machine 3 (see Figure 11 and Figure 12 ), the portable smoke machine 3 comprises a smoke machine housing 31 having a spray end 311, a smoke control component 32, an air supply component 33 and an atomizing component 34 are arranged on the smoke machine housing 31, the air supply component 33 and the atomizing component 34 are electrically connected to the smoke control component 32, respectively, and the air supply component 33 is connected to the atomizing component 34 to blow the smoke generated by the atomizing component 34 to the spray end 311;

[0072] Mist blowing device 1 (see Figure 5 , Figure 6 , Figure 7 as well as Figure 8 ), the mist blowing device 1 includes a fan housing 11, a smoke channel 13, an air flow channel 12 formed in the fan housing 11, a fan driver 14 arranged in the fan housing 11, and an impeller 15 which is transmission-connected to the fan driver 14 and is located in the air flow channel 12, the smoke channel 13 is formed on the fan housing 11 or arranged at the periphery of the fan housing 11, the air flow channel 12 has an air inlet side 121 and an air outlet side 122, the two ends of the smoke channel 13 along its own extension direction are respectively a mist inlet port 131 and a mist outlet port 132, the mist inlet port 131 is used to connect to the spray end 311, and the mist outlet port 132 is located at the air outlet side 122 or around the air outlet side 122.

[0073] In the hand-held thin smoke system of the present utility model, through a new purging and atomizing principle, the atomizing efficiency is greatly improved, so that a thin smoke effect can be achieved through an existing power module with high power (such as a lithium battery), thereby realizing the miniaturization and integration of the product. The portable smoke machine 3 of the hand-held thin smoke system uses high-concentration glycerol as the main component of the atomizing agent to form smoke with slow dissipation and high concentration, and then the blowing device 1 quickly disperses the high-concentration smoke and sprays it into the clean air of the application scenario to quickly form a low-concentration smoke aerosol.

[0074] Specifically, in the portable smoke machine 3, the smoke control component 32 is used to control the air supply component 33 and the atomizing component 34 respectively. The atomizing component 34 is used to generate high-concentration smoke, and the air supply component 33 is used to send the high-concentration smoke to the spray end 311.

[0075] The innovation of the present utility model lies in the combination method of the blowing device 1 and the portable smoke machine 3, and more lies in the setting method of the smoke channel 13. That is, the air flow channel 12 has an air inlet side 121 and an air outlet side 122. The two ends of the smoke channel 13 along its own extension direction are respectively an inlet fog port 131 and an outlet fog port 132. The inlet fog port 131 is used to communicate with the spray end 311, and the outlet fog port 132 is located at or around the air outlet side 122. Such a setting can avoid smoke from polluting the air flow channel 12 and the impeller 15. It should be noted that the smoke channel 13 can not only be integrally formed on the fan housing 11, but also be connected to the fan housing 11 through existing combination technologies such as screws, adhesives, hot pressing, welding, and snap-fitting. The fan driver 14 can be a driving motor, and the rotation speed of the impeller 15 can be adjusted.

[0076] It should be emphasized that: the smoke channel 13 is formed on the fan housing 11 or arranged around the fan housing 11 (the specific embodiment corresponding to the arrangement around the fan housing 11 is not shown). That is to say, the smoke channel 13 can be a through hole directly opened on the fan housing 11, or can be composed of the lumen of a trachea (such as a metal pipe or a plastic pipe). Among them, the trachea can be arranged on the outer wall of the fan housing 11 through an existing connection method. One end of the trachea forms the inlet fog port 131 and is inserted into the spray end 311, and the other end forms the outlet fog port 132 and is located at or around the air outlet side 122. When the trachea is inserted into the spray end 311 of the portable smoke machine 3, the fan housing 11 of the blowing device 1 can be connected to the trachea and / or the smoke machine housing 31 through a fixing structure.

[0077] Another point that needs to be emphasized is that the smoke channel 13 is a part of the mist blowing device 1, and the smoke channel 13 is not a part of the portable smoke machine 3, that is, the smoke channel 13 is a structure independent of the portable smoke machine 3. The spray end 311 can be designed in an integrated manner with the spray port of the atomizing component 34, for example, the spray port of the atomizing component 34 directly constitutes the spray end 311. The spray end 311 can also be designed separately from the spray port of the atomizing component 34, for example, the portable smoke machine 3 also includes a spray channel formed in the smoke machine housing 31, and the upper and lower ends of the spray channel are respectively connected to the spray end 311 and the spray port of the atomizing component 34. Specifically, the spray channel extends up and down along the height direction of the portable smoke machine 3, the upper end of the spray channel is connected to the spray end 311, and the lower end of the spray channel is connected to the spray port of the atomizing component 34.

[0078] Compared with the existing handheld mist machine, the handheld mist system of the utility model has the following specific technical effects:

[0079] First, the smoke of the existing handheld mist machine solution enters the fan from the air inlet side of the fan. After long-term use, the condensed oil accompanying the smoke aerosol will accumulate on the fan blades and the air duct surface, which is difficult to clean. At the same time, the leaking liquid is prone to secondary pollution, and the fan efficiency is affected after the dust is absorbed. In contrast, the handheld mist system of the utility model guides the smoke to the air outlet side 122 of the air flow channel 12 through the smoke channel 13, avoiding the smoke from passing through the impeller 15 and avoiding the pollution problem.

[0080] Second, the fan and the main unit of the existing mist machine are connected through accessories. Since the fan is heavy, the overall center of gravity of the device is forward and easy to fall over. At the same time, the additional connecting accessories make disassembly and assembly more troublesome and easy to damage. In contrast, the handheld mist system of the utility model can be directly detachably connected to the spray end 311 of the portable mist machine 3 through the lightweight mist blowing device 1 and the mist inlet port 131 of the smoke channel 13.

[0081] Therefore, the handheld thin smoke system of the utility model can prevent the air flow channel and the impeller of the mist blowing device from being contaminated by the smoke generated by the portable smoke machine, and can enable the mist blowing device to cleverly use the mist inlet port of the smoke channel to be directly and quickly connected to the spray end of the portable smoke machine.

[0082] As a specific embodiment of the connection between the smoke channel 13 and the spray end 311: standard structures such as flange structure, quick assembly and disassembly structure, silicone sealing structure, screw fixing structure, buckle structure, magnetic suction joint, etc. can be used to achieve assembly and separation, and indirect connection can also be achieved by adding or extending the hard pipe or hose. The specific configuration form can be reasonably configured according to the actual usage of the target user.

[0083] In the existing solution of installing a fan on a handheld smoke machine, the existing fan and the existing main unit need to be connected through accessories. Since the existing fan is heavy and the overall center of gravity of the device is near the head, the device is prone to tipping over, which increases the usage limitations of the product. At the same time, adding connection accessories makes disassembly and assembly troublesome and easily damaged. In contrast, in the handheld thin smoke system of the present application, in order to simplify the structure of the connection and docking, the self-weight of the fog blowing device is reduced through lightweight design so that it can be connected and fixed in an inserted manner between the fog inlet port 131 and the spray end 311. For example, the fog inlet port 131 is a male socket and the spray end 311 is a female socket.

[0084] Furthermore, in order to facilitate the on-line operation of the staff, the portable smoke machine 3 further includes a smoke communication module 35 electrically connected to the smoke control component 32; the fog blowing device 1 further includes a fog blowing control component 16 and a fog blowing communication module 17. The fog blowing communication module 17 and the fan driver 14 are respectively electrically connected to the fog blowing control component 16, and the fog blowing communication module 17 is communicatively connected to the smoke communication module 35 to receive the operation instructions issued by the portable smoke machine 3. At the same time, the integrated linkage control method enables the portable smoke machine and the fog blowing device to be integrated and manipulated with one hand.

[0085] The smoke control component 32 may include a smoke circuit board and a smoke battery. The smoke circuit board may include button and charging port features; the speed and start / stop of the impeller of the fog blowing device 1 are adjusted using buttons or knobs. In addition, the fog blowing control component 16 may also include a fog blowing circuit board and a fog blowing battery. The fog blowing circuit board may include button and charging port features, and the speed and start / stop of its own impeller can also be adjusted using buttons or knobs. Among them, as a specific embodiment of the button: in the form of a physical button, a remote control or a wire-controlled MOS tube or relay.

[0086] In addition, there are four specific implementation methods:

[0087] The first specific embodiment: A remote control is used to control the speed or start / stop of the portable smoke machine 3 and the fog blowing device 1 separately or synchronously to achieve joint control.

[0088] The second specific embodiment: The smoke control component 32 and the fog blowing control component 16 are integrated into one body, and then connected to the fan driver 14 through wires to achieve the control and conduction of the components to control the speed and start / stop of the impeller.

[0089] The third specific embodiment: The smoke control component 32 is directly connected to the fan driver 14 through wires, and the speed and start / stop of the impeller are controlled by directly controlling the level and on / off of the output voltage.

[0090] The fourth specific embodiment: The portable smoke machine 3 and the fog blowing device 1 are independently controlled; this embodiment increases the difficulty of operation.

[0091] As a specific embodiment of the communication method between the smoke communication module 35 and the fog-blowing communication module 17: one or several of a radio frequency module, a WiFi module, Bluetooth, a wireless DMX transceiver, and a wired DMX transceiver can be adopted. The specific configuration form can be reasonably configured according to the actual usage situation of the target user.

[0092] The fog-blowing device 1 can be one of an axial flow fan, a turbo blower fan (blower type), an electric fan type open fan (small fan), or a high-speed axial flow fan driven by a brushless motor. An air inlet grille can be provided on the air inlet side 121, and an air outlet grille can be provided on the air outlet side 122. The main function is to protect the hand from reaching into the impeller and modulate the jet flow path for generating the fluid. Preferably, the role of the fog-blowing device 1 in the present utility model is to generate a fluid to accelerate the smoke and spray it farther so as to achieve the purpose of rapid dilution and diffusion. Accelerating the smoke can make it quickly turn into a mist and become uniform. By increasing the length of the blades and reducing the effective cross-sectional area on the air outlet side, sacrificing a certain flow rate, the fluid characteristics are rectified from a spiral diffusion type air flow to a high-speed converging type air flow, enabling it to be sprayed farther with a smaller spraying area and a higher flow velocity. At the same time, the Bernoulli principle can be utilized, and the high-speed converging type air flow further guides the surrounding air to move, achieving the effect of increasing the flow rate. For example, in order to blow the smoke farther, the air flow channel 12 is an axial flow air cavity. The front and rear sides of the axial flow air cavity along its own axis respectively constitute the air inlet side 121 and the air outlet side 122. The effective passing cross-sectional area of the axial flow air cavity near the air outlet side 122 is smaller than the effective passing cross-sectional area of the axial flow air cavity near the air inlet side 121. In order to blow the smoke farther, the air inlet area of the air inlet side 121 is larger than the air outlet area of the air outlet side 122.

[0093] The fan driver 14 can be a brushless motor (see Figure 9 ), or it can also be a traditional motor (such as a brushed motor, see Figure 10 ). Since the traditional motor has brushes that will wear, generally only two commutations are performed in each rotation cycle, and the commutation interval is relatively large during the work process. Coupled with the weight of the rotor, the rotation speed is relatively slow, and it is also very difficult to calibrate and solve the dynamic balance problem of the vibration. The brushless motor has no brushes, and the resistance is small itself. Because the commutation of the electromagnet is driven by a program, and the number of coils can be increased at the same time, multiple commutations and work can be achieved in the same rotation cycle, and the work can be more intensive and continuous. Moreover, the coaxiality of the central axis is easily guaranteed. Only by separately calibrating the dynamic balance of the impeller and the pressed-in magnetic ring, the dynamic balance during the operation of the impeller can be basically achieved. In addition, the housing structure of the brushed motor is cancelled, and the stator, rotor, and bearing are directly assembled with the structural parts of the fog-blowing device, and the weight is very light. Therefore, it is relatively easy to achieve light weight, high rotation speed, low vibration, and low noise.

[0094] The fan driver 14 of the mist blowing device 1 generally adopts a brushed or brushless motor driven by low-voltage direct current (within 36V). The impeller 15 is a rotating body rotating around an axis, and has two or more blades that can achieve dynamic balance during rotation, and the combination constitutes the air outlet structure of the mist blowing device.

[0095] Furthermore, in order to further rectify the spiral diffusion wind flow into a high-speed convergent wind flow, the wind outlet side 122 is provided with an air guide grille 123, and the air guide grille 123 includes a central blocking portion 123a and an annular air outlet portion 123b formed at the periphery of the central blocking portion 123a.

[0096] Furthermore, in order to fully utilize the space on the windward side of the central blocking portion 123 a and improve the compactness of the mist blowing device 1 , a receiving compartment 124 for installing the fan driver 14 is formed on the windward side of the central blocking portion 123 a , and the opening of the receiving compartment 124 faces the impeller 15 .

[0097] Furthermore, in order to reduce wind resistance and further rectify the spiral diffusion wind flow into a high-speed convergent wind flow, the impeller 15 includes a hub 151 drivingly connected to the fan driver 14 and a plurality of blades 152 disposed on the hub 151. The hub 151 is a shroud structure with a single-side opening, the opening of the hub 151 is larger than the opening of the accommodating chamber 124, and the opening of the hub 151 is aligned with the opening of the accommodating chamber 124. In some specific embodiments, the hub 151 may be a conical shell or a hemispherical shell.

[0098] Furthermore, the smoke channel 13 includes a first guide section 133 for connecting to the spray end 311 and a second guide section 134 connected to the first guide section 133, and the angle between the first guide section 133 and the second guide section 134 is 90 degrees to 180 degrees; the smoke channel 13 is made of heat dissipation material and / or high temperature resistant material. The angle between the first guide section 133 and the second guide section 134 should ideally be an obtuse angle, because long-term smoke spraying will be accompanied by high temperature, and an obtuse angle is conducive to heat dissipation and reducing heat accumulation.

[0099] Furthermore, in order to further accelerate the dilution of the smoke and spray it farther, the handheld thin smoke system also includes a guide extension tube 2, and the two ends of the guide extension tube 2 along its own extension direction are respectively a first end 21 and a second end 22, the first end 21 is used to connect to the mist outlet port 132, and there is a preset distance between the second end 22 and the air outlet side 122, and the second end 22 is aligned with the axis of the impeller 15.

[0100] As a specific embodiment of the portable smoke machine 3: Figure 2As shown, the atomization component 34 is in communication with the air supply component 33. The smoke control component 32 is equipped with a human-machine interaction function. Both the atomization component 34 and the air supply component 33 are connected to the smoke control component 32 through wires. The air supply component 33 and the atomization component 34 are arranged in the internal space of the smoke machine housing 31 from low to high, and the smoke control component 32 is arranged on one side of the internal space of the smoke machine housing 31.

[0101] The smoke control component 32 is integrated with a micro-control unit, and the micro-control unit realizes the adjustment and control of the atomization component 34 and the air supply component 33 through software, that is, controls the concentration, speed, and spraying duration of the output smoke by adjusting the voltage and current of the atomization component 34 and the air supply component 33.

[0102] The atomization component 34 includes a heating element, a cooler, a liquid supply device, and a liquid storage chamber. The liquid storage chamber stores a liquid atomizing agent, and the liquid atomizing agent can be transported to the heating element through the liquid supply device. The cooler is located at the bottom or around the heating element and is in communication with the air supply component 33 through an air duct. The heating element is connected to the smoke control component 32 through a wire. When the atomization component 34 is working, the liquid atomizing agent in the liquid storage chamber is transported to the heating element through the liquid supply device. After the heating element is powered on under the control of the smoke control component 32, it heats the liquid atomizing agent. At the same time, the cooler transports cooling air to the surface of the heating element through the air supply component 33, so that the liquid atomizing agent heated to the vapor state is quickly condensed, thereby realizing the atomization of the liquid atomizing agent and blowing it out of the atomization component.

[0103] Preferably, the air supply component 33 is a fan or an air pump.

[0104] In summary, the handheld thin smoke system of the present utility model can avoid the air flow channel and impeller of the fog blowing device from being polluted by the smoke generated by the portable smoke machine, and can enable the fog blowing device to be quickly and directly connected to the spray end of the portable smoke machine by skillfully utilizing the fog inlet port of the smoke channel. The fog outlet port has the ability to further install pipes and accessories, and can be integrally controlled through a linkage scheme. Therefore, the present utility model effectively overcomes various disadvantages in the prior art and has high industrial utilization value.
