Description

Technical Field

[0001] The utility model relates to the technical field of smoke bubble machines, in particular to a handheld smoke bubble system. Background Art

[0002] Bubble machines are a popular children's toy that can automatically generate a large number of bubbles, bringing fun to children. According to the search results, the main functions of bubble machines include entertainment, decoration, education, and advertising. They are not only suitable for children but also loved by adults, especially as decorations during picnics or photo shoots.

[0003] The characteristic of bubble machines is that they can generate many bubbles at once, saving time and effort. They help exercise children's fine motor skills, visual pursuit ability, and hand-eye coordination ability.

[0004] The working principle of bubble machines is relatively simple. It mainly blows bubble liquid through a mechanical device to form bubbles. Specifically, bubble machines usually contain soapy water or special bubble liquid inside. When starting, the fan or nozzle inside the machine blows out these liquids to form bubbles. These bubbles will float with the air flow, and at the same time, the air flow generated by the fan or nozzle helps the stability of the bubbles and the perfection of their shape. The core components of bubble machines include a motor and a blower, a liquid container, a turntable or a perforated mesh structure, and a circuit controller. The motor drives the blower to generate an air flow, and the bubble liquid is blown out through the small holes on the turntable or mesh structure to form bubbles.

[0005] The bubble liquid of bubble machines is generally composed of water, soap, and glycerin. These components are mixed to form a liquid with surface tension, which helps form a stable bubble film. During the blowing process of bubble machines, the rotating bubble rod or fan blows air into the bubble liquid to form hollow bubbles. The stability of bubbles is affected by various factors, including humidity and temperature in the air. Usually, when the relative humidity is low or the outdoor temperature is low, bubbles are easy to form and last longer.

[0006] The existing patent document (application number: CN202020137297.7) discloses a swinging bubble machine. On the basis of the bubble machine, an atomization module is added in the hope of achieving the effect of bubbles with smoke. However, in the implementation scheme, the smoke generated by the atomization module is extremely light, and at the same time, there is a lack of external wind force for releasing bubbles. It is necessary to release the bubbles with smoke by means of manual swinging.

[0007] The existing patent document (application number: US10998100) also discloses a generator for encapsulating fluid in bubbles. It ingeniously sets a fan between the atomizing part and the bubble part. The fan generates a flowing air current, which flows through the atomizing part to produce smoke and then blows out bubbles. This solution also adds an oil pump to replenish the atomizing part with liquid. By adding a liquid replenishing mechanism, the bubble nozzle 4 is continuously replenished with bubble liquid to achieve the effect of continuously outputting bubbles. At the same time, through the non-closed bubble nozzle 4, that is, the wind with smoke blown out not only enters the bubble closed area to form smoke bubbles, but also flows through the periphery of the smoke bubbles through the gap to provide the power for blowing out bubbles. There are two deficiencies in this solution: First, blowing out bubbles requires a large flow of flowing gas. Therefore, in order to accelerate the smoke, it will be quickly diluted, and the smoke in the smoke bubbles is very light. Second, both the wind in the bubble blowing and the wind blowing into the bubble are winds with faint smoke. The smoke bubbles are blown out mixed in the wind with smoke, lacking contrast and having a poor effect. Summary of the Utility Model

[0008] In view of the above-mentioned disadvantages of the prior art, the technical problem to be solved by the present utility model is to provide a handheld smoke bubble system, which can not only generate smoke bubbles containing high-concentration smoke, but also the smoke bubbles are blown by a high-speed clean air current generated by a purging device, so as to be separated from the bubble nozzle and released into the environment. The high-concentration smoke only exists inside the smoke bubbles, forming a more special atmosphere effect.

[0009] To solve the above technical problems, the present utility model provides a handheld smoke bubble system, including:

[0010] A portable smoke machine, which has a spraying end;

[0011] A purging device, which includes a fan housing, a smoke passage, an air current passage formed in the fan housing, a fan driver provided on the fan housing, and an impeller that is in transmission connection with the fan driver and is located in the air current passage. The smoke passage is formed on the fan housing or arranged around the fan housing. The air current passage has an air inlet side and an air outlet side. The two ends of the smoke passage along its extending direction are respectively a smoke inlet port and a smoke outlet port. The smoke inlet port is used to communicate with the spraying end;

[0012] A bubble nozzle, which has a bubble generating end and a connecting end. The bubble generating end is used to generate smoke bubbles, and the connecting end is used to communicate with the smoke outlet port. When the bubble nozzle is communicated with the smoke passage, the bubble generating end is located on the air outlet side or within the purging range corresponding to the air outlet side.

[0013] Further, the portable smoke machine further includes a smoke machine housing having the spray end, and a smoke control component, a gas supply component, and an atomization component are provided on the smoke machine housing. The gas supply component and the atomization component are respectively electrically connected to the smoke control component, and the gas supply component communicates with the atomization component to blow the smoke generated by the atomization component to the spray end.

[0014] Further, the portable smoke machine further includes a smoke communication module electrically connected to the smoke control component; the purging device further includes a purging control component and a purging communication module. The purging communication module and the fan driver are respectively electrically connected to the purging control component, and the purging communication module is communicatively connected to the smoke communication module to receive the operation instruction issued by the portable smoke machine.

[0015] Further, the air flow channel is an axial flow air cavity. The front and rear sides of the axial flow air cavity along its own axis respectively constitute an air inlet side and an air outlet side. The effective passing cross-sectional area of the axial flow air cavity near the air outlet side is smaller than the effective passing cross-sectional area of the axial flow air cavity near the air inlet side.

[0016] Further, a wind guide grille is provided on the air outlet side. The wind guide grille includes a central blocking portion and an annular air outlet portion formed on the outer periphery of the central blocking portion; the opening direction of the foaming end of the bubble nozzle faces away from the air outlet side, and the projection of the foaming end of the bubble nozzle toward the air outlet side falls on the central blocking portion so that the air flow generated by the purging device passes through the periphery of the bubble nozzle.

[0017] Further, a receiving bin for installing the fan driver is formed on the windward side of the central blocking portion, and the opening of the receiving bin faces the impeller.

[0018] Further, the impeller includes a hub drivingly connected to the fan driver and a plurality of blades provided on the hub. The hub has a one-sided open flow guide cover structure. The opening of the hub is larger than the opening of the receiving bin, and the opening of the hub is aligned with the opening of the receiving bin.

[0019] Further, the smoke channel includes a first diversion section for communicating with the spray end and a second diversion section communicating with the first diversion section. The included angle between the first diversion section and the second diversion section is 90 degrees to 180 degrees; the smoke channel is made of heat dissipation material and / or high temperature resistant material.

[0020] Further, the handheld smoke bubble system further includes a diversion extension tube, and the bubble nozzle is connected to the fog outlet port through the diversion extension tube.

[0021] As described above, the handheld smoke bubble system of the present utility model has the following beneficial effects: A portable smoke machine is used as the smoke source, and a connected flow channel allowing smoke to flow through is formed through a smoke channel and a bubble nozzle. A blowing device is arranged near the bubble nozzle to output wind that can act on the smoke bubbles. That is, a portable smoke machine provides high-concentration smoke with a low flow rate, and the high-concentration smoke is blown to the bubble nozzle to form smoke bubbles. At the same time, since the smoke bubbles are located on the air outlet side or within the blowing range corresponding to the air outlet side, the smoke bubbles are blown by the high-speed clean air flow generated by the blowing device, so as to separate from the bubble nozzle and be released into the environment. Under the solution of the present utility model, all the high-concentration smoke generated by the portable smoke machine flows into the bubbles; when the high-concentration smoke is milky white, the smoke bubbles will also present a milky white texture. Since the smoke bubbles have high-concentration smoke with a density much higher than that of air, under the action of the gravity of the high-concentration smoke, the smoke bubbles can fall faster than ordinary bubbles (ordinary bubbles are bubbles without smoke), forming a very special visual effect. At the same time, the air flow generated by the blowing device is clean and free of smoke. During the generation of the smoke bubbles, the environment will not be polluted by the smoke air flow, and the environment can remain transparent. Only the smoke bubbles are filled with high-concentration smoke, thus achieving a special atmosphere effect. Further, by adjusting the blowing power of the blowing device, that is, adjusting the speed of the clean air flow, the state of the smoke bubbles can be adjusted between simply blowing out large smoke bubbles and further splitting the large smoke bubbles into multiple small smoke bubbles, so as to achieve a special visual effect of falling like snowflakes all over the sky.

[0074] 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.

[0075] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance.

The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantial change of the technical content.

[0076] For ease of description, Figure 11 As 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.

[0077] Also for the convenience of description, Figure 13 , Figure 14 , Figure 15 , Figure 16 as well as Figure 17 As shown, the solid curved arrow indicates the flow direction of the high-concentration smoke generated by the portable smoke machine 3 , and the non-solid straight arrow indicates the flow direction of the wind flow generated by the purge device 1 .

[0078] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, the utility model provides a handheld smoke bubble system, comprising:

[0079] A portable smoke machine 3, wherein the portable smoke machine 3 has a spray end 311;

[0080] Blowing device 1, the blowing device 1 includes a fan housing 11, a smoke passage 13, an air flow passage 12 formed in the fan housing 11, a fan driver 14 provided on the fan housing 11, and an impeller 15 that is drivingly connected to the fan driver 14 and is located in the air flow passage 12. The smoke passage 13 is formed on the fan housing 11 or arranged at the periphery of the fan housing 11. The air flow passage 12 has an air inlet side 121 and an air outlet side 122. The two ends of the smoke passage 13 along its extending direction are respectively a fog inlet port 131 and a fog outlet port 132. The fog inlet port 131 is used to communicate with the spraying end 311;

[0081] Bubble nozzle 4, the bubble nozzle 4 has a foaming end 41 and a connecting end 42. The foaming end 41 is used to generate smoke bubbles 5, and the connecting end 42 is used to communicate with the fog outlet port 132. When the bubble nozzle 4 is communicated with the smoke passage 13, the foaming end 41 is located on the air outlet side 122 or within the blowing range corresponding to the air outlet side 122.

[0082] In the handheld smoke bubble system of the present utility model, a portable smoke machine 3 is used as the smoke source. A connected flow path allowing smoke to flow through is formed through the smoke passage 13 and the bubble nozzle 4. By providing a blowing device 1 near the bubble nozzle 4, a wind force that can act on the smoke bubbles 5 is output. That is, a high-concentration smoke with a low flow rate is provided by the portable smoke machine 3, and the high-concentration smoke is blown to the bubble nozzle, thereby forming smoke bubbles. At the same time, since the smoke bubbles are located on the air outlet side 122 or within the blowing range corresponding to the air outlet side 122, the smoke bubbles are blown by the high-speed clean air flow generated by the blowing device 1, so as to separate from the bubble nozzle 4 and be released into the environment.

[0083] Under the solution of the present utility model, all the high-concentration smoke generated by the portable smoke machine 3 flows into the bubbles; when the high-concentration smoke is milky white, the smoke bubbles will also present a milky white texture. Since the smoke bubbles have a high-concentration smoke with a density much higher than that of air, under the action of the gravity of the high-concentration smoke, the smoke bubbles can fall faster than ordinary bubbles (ordinary bubbles are bubbles without smoke), forming a very special visual effect. At the same time, the air flow generated by the blowing device 1 is clean and free of smoke. During the generation of the smoke bubbles, the environment will not be polluted by the smoke air flow, and the environment can remain transparent. Only the smoke bubbles are filled with high-concentration smoke, thus achieving a special atmosphere effect. Further, by adjusting the blowing power of the blowing device 1, that is, adjusting the speed of the clean air flow, the state of the smoke bubbles can be adjusted between simply blowing out large smoke bubbles and further splitting the large smoke bubbles into multiple small smoke bubbles, so as to achieve a special visual effect of falling like snowflakes all over the sky.

[0084] Let's emphasize the innovation points of the handheld smoke bubble system of the present utility model again: In the solutions of existing patent documents (application numbers: CN202020137297.7 and US10998100): A single gas source simultaneously provides the cooling gas required for smoke atomization. This cooling gas provides the wind pressure required to blow up the smoke bubbles while providing the release wind force required to blow out the smoke bubbles.

[0085] On the contrary, in the solution of the handheld smoke bubble system of the present utility model: The portable smoke machine 3 provides a gas source with low flow and high pressure, generating a high-concentration smoke aerosol, which can blow up larger-sized smoke bubbles. At the same time, the purging device 1 provides a wind force with high flow and low pressure, providing the power to blow the smoke bubbles away from the bubble nozzle 4, and further providing the power to cause the smoke bubbles to split into additional smoke bubbles. Another point is that the air flow generated by the purging device 1 is clean.

[0086] Therefore, the handheld smoke bubble system of the present utility model can not only generate smoke bubbles containing high-concentration smoke, but also the smoke bubbles are blown by the high-speed clean air flow generated by the purging device 1, so as to separate from the bubble nozzle 4 and be released into the environment. The high-concentration smoke only exists inside the smoke bubbles, forming a more special atmosphere effect.

[0087] In the handheld smoke bubble system of the present utility model, through a new smoke bubble generation principle, a more special smoke bubble atmosphere effect can be achieved through a high-power existing power module (such as a lithium battery), thus realizing the miniaturization and integration of the product. The portable smoke machine 3 of the handheld smoke bubble system uses high-concentration glycerol as the atomizing agent to form slow-dispersing and high-concentration smoke, and then the purging device 1 releases the smoke bubbles containing high-concentration smoke into the environment.

[0088] Furthermore, the portable smoke machine 3 further includes a smoke machine housing 31 having the spray end 311. A smoke control assembly 32, a gas supply assembly 33, and an atomizing assembly 34 are provided on the smoke machine housing 31. The gas supply assembly 33 and the atomizing assembly 34 are respectively electrically connected to the smoke control assembly 32, and the gas supply assembly 33 communicates with the atomizing assembly 34 to blow the smoke generated by the atomizing assembly 34 to the spray end 311.

[0089] Specifically, in the portable smoke machine 3, the smoke control assembly 32 is used to respectively control the gas supply assembly 33 and the atomizing assembly 34. The atomizing assembly 34 is used to generate high-concentration smoke, and the gas supply assembly 33 is used to send the high-concentration smoke to the spray end 311.

[0090] The main innovation of the present utility model lies in the combination manner of the purging device 1, the portable smoke machine 3 and the bubble nozzle, and also lies in the setting manner of the smoke passage 13. That is, the air flow passage 12 has an air inlet side 121 and an air outlet side 122. The two ends of the smoke passage 13 along its extending direction are respectively a fog inlet port 131 and a fog outlet port 132. The fog inlet port 131 is used to communicate with the spraying end 311, and the bubble nozzle connected to the fog outlet port 132 is located on the air outlet side 122 or within the purging range corresponding to the air outlet side 122. With such a setting, it can avoid the smoke from polluting the air flow passage 12 and the impeller 15. It should be noted that the smoke passage 13 can not only be integrally formed on the fan housing 11, but also be connected to the fan housing 11 by existing connection methods such as bolts and adhesives. The fan driver 14 can be a driving motor, and the rotation speed of the impeller 15 can be adjusted.

[0091] It should be emphasized that: the smoke passage 13 is formed on the fan housing 11 or arranged around the fan housing 11. That is to say, the smoke passage 13 can be a through hole directly opened on the fan housing 11, or can be formed by the lumen of a trachea (such as a metal tube or a plastic tube). Among them, the trachea can be arranged on the outer wall of the fan housing 11 by an existing connection method. One end of the trachea forms the fog inlet port 131 and is inserted into the spraying end 311, and the other end forms the fog outlet port 132 and is located on the air outlet side 122 or around the air outlet side 122. When the trachea is inserted into the spraying end 311 of the portable smoke machine 3, the fan housing 11 of the purging device 1 can be connected to the trachea and / or the smoke machine housing 31 through a bracket.

[0092] Another point that needs to be emphasized is that: the smoke passage 13 belongs to a part of the purging device 1 and does not belong to a part of the portable smoke machine 3, that is, the smoke passage 13 is a structure independent of the portable smoke machine 3. The spraying end 311 can be integrally designed with the spraying port of the atomizing component 34. For example, the spraying port of the atomizing component 34 directly forms the spraying end 311. The spraying end 311 can also be separately designed from the spraying port of the atomizing component 34. For example, the portable smoke machine 3 further includes a spraying passage formed in the smoke machine housing 31. The upper and lower ends of the spraying passage are respectively communicated with the spraying end 311 and the spraying port of the atomizing component 34. Specifically, the spraying passage extends up and down along the height direction of the portable smoke machine 3. The upper end of the spraying passage is communicated with the spraying end 311, and the lower end of the spraying passage is communicated with the spraying port of the atomizing component 34.

[0093] Specific embodiments of the connection method between the smoke channel 13 and the spray end 311: Standard structures such as flange structures, quick-connect and quick-disconnect structures, silicone seal structures, screw-thread fixing structures, snap structures, magnetic connectors, etc. can be used to achieve assembly and separation. Indirect connection can also be achieved by adding or extending hard pipes and hoses for connection. The specific configuration form can be reasonably configured according to the actual usage of the target user.

[0094] Specific embodiments of the connection method between the smoke channel 13 and the bubble nozzle: Standard structures such as flange structures, quick-connect and quick-disconnect structures, silicone seal structures, screw-thread fixing structures, snap structures, magnetic connectors, etc. can be used to achieve assembly and separation. Indirect connection can also be achieved by adding or extending hard pipes and hoses for connection. The specific configuration form can be reasonably configured according to the actual usage of the target user.

[0095] In the existing solution of adding a fan to a handheld smoke machine, the existing fan and the existing main body need to be connected through accessories. Since the existing fan is relatively heavy and the overall center of gravity of the device is at the head, the device is prone to tipping over, increasing the usage limitations of the product. At the same time, adding connection accessories makes disassembly and assembly troublesome and easy to damage. In contrast, in the handheld smoke and bubble system of the present invention, further, in order to simplify the connection and docking structure, the connection method between the fog inlet port 131 and the spray end 311 is an insertion method. For example, the fog inlet port 131 is a male socket, and the spray end 311 is a female socket.

[0096] Further, the portable smoke machine 3 further includes a smoke communication module 35 electrically connected to the smoke control component 32; the purging device 1 further includes a purging control component 16 and a purging communication module 17. The purging communication module 17 and the fan driver 14 are respectively electrically connected to the purging control component 16, and the purging 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 purging device to be integrally controlled with one hand.

[0097] Furthermore, the smoke control component 32 can include a smoke circuit board and a smoke battery, and the smoke circuit board can include button and charging port features; buttons or knobs are used to adjust the rotation speed, start and stop of the impeller of the purging device 1. In addition, the purging control component 16 can also include a purging circuit board and a purging battery, and the purging circuit board can include button and charging port features. Buttons or knobs can also be used to adjust the rotation speed, start and stop of its own impeller. Among them, as specific embodiments of the button: in the form of physical buttons, remote control or wire control MOS tubes or relays.

[0098] In addition, there are four specific implementation methods:

[0099] First specific embodiment: A remote controller is used to control the start and stop of the portable smoke machine 3 and the purging device 1 separately or synchronously to achieve joint control.

[0100] Second specific embodiment: The smoke control component 32 and the purging 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, so as to control the rotation speed, start and stop of the impeller.

[0101] Third specific embodiment: The smoke control component 32 is directly connected to the fan driver 14 through wires, and directly controls the rotation speed, start and stop of the impeller by controlling the level and on / off of the output voltage.

[0102] Fourth specific embodiment: The portable smoke machine 3 and the purging device 1 are independently controlled; this embodiment increases the difficulty of operation.

[0103] As a specific embodiment of the communication method between the smoke communication module 35 and the purging 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.

[0104] The purging 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 function of the purging device 1 in the present invention is to generate a fluid to accelerate the separation of smoke bubbles and blow the smoke bubbles farther. By increasing the length of the blades and reducing the air outlet side area, sacrificing a certain flow rate, the fluid characteristics are rectified from a spiral diffusive air flow to a high-speed converging air flow, enabling it to be ejected farther with a smaller jet area and a higher flow rate. At the same time, the Bernoulli principle can be utilized, and the high-speed converging 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 bubbles farther, the air flow channel 12 is an axial flow air cavity, and the front and rear sides of the axial flow air cavity along its own axis respectively form 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 bubbles farther, the air inlet area of the air inlet side 121 is larger than the air outlet area of the air outlet side 122.

[0105] 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). Traditional motors have brushes that will wear out, and generally only perform two commutations per rotation cycle. There are intervals between work, and due to the weight of the rotor, the speed is relatively slow, and the dynamic balance of vibration problems is difficult to calibrate. Brushless motors have no brushes, so the resistance itself is small. Because the commutation of the electromagnet is driven by the program, the number of coils can be increased at the same time, and multiple commutations in the same rotation cycle can be achieved, which can achieve more intensive and continuous work. In addition, the coaxiality of the central axis is easy to ensure. Only the impeller and the pressed magnetic ring need to be calibrated separately to achieve the dynamic balance of the impeller during operation. In addition, the outer shell structure of the brushed motor is eliminated, and the stator, rotor, and bearing are directly assembled with the structural parts of the mist blowing device. The weight is very light, so it is easier to achieve lightweight, high speed, low vibration and noise.

[0106] The fan driver 14 of the purge 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, having two or more blades, which can achieve dynamic balance during rotation, and the combination constitutes the air outlet structure of the purge device.

[0107] Furthermore, in order to further rectify the spiral diffusion windflow into a high-speed convergent windflow and blow the smoke bubbles farther, 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; the opening direction of the bubble end 41 of the bubble nozzle 4 is opposite to the wind outlet side 122, and the projection of the bubble end 41 of the bubble nozzle 4 toward the wind outlet side 122 falls on the central blocking portion 123a so that the windflow generated by the purge device 1 passes through the periphery of the bubble nozzle 4.

[0108] 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 purge 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 .

[0109] 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.

[0110] Further, the smoke channel 13 includes a first diversion section 133 for connecting to the spraying end 311 and a second diversion section 134 connected to the first diversion section 133. The angle between the first diversion section 133 and the second diversion section 134 is 90 degrees to 180 degrees; the smoke channel 13 is made of heat-dissipating material and / or high-temperature resistant material. The angle between the first diversion section 133 and the second diversion section 134 is preferably an obtuse angle because long-term spraying of smoke is accompanied by high temperature, and the obtuse angle is beneficial to heat dissipation and reduces heat accumulation.

[0111] Further, in order to blow the smoke bubbles further, the handheld smoke bubble system further includes a diversion extension tube 2. The bubble nozzle 4 is connected to the fog outlet 132 through the diversion extension tube 2. The two ends of the diversion 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 fog outlet 132, and the second end 22 is used to connect to the bubble nozzle.

[0112] As a specific embodiment of the portable smoke machine 3: as Figure 2 shown, the atomization component 34 is connected to the air supply component 33. The smoke control component 32 is equipped with a human-computer 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.

[0113] 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.

[0114] The atomization component 34 includes a heating element, a cooler, a liquid supply device and a liquid storage bin. The liquid storage bin stores a liquid atomizing agent. 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 connected to 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 bin 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.

[0115] Preferably, the air supply component 33 is a fan or a gas pump.

[0116] The present invention also provides a method for generating smoke bubbles, including the following steps:

[0117] Assemble the portable smoke machine 3, the purging device 1, and the bubble nozzle 4;

[0118] Dip the bubble nozzle 4 into the bubble liquid;

[0119] Use the atomization component 34 of the portable smoke machine 3 to continuously and stably generate high-concentration smoke, and use the air supply component 33 of the portable smoke machine 3 to blow all the high-concentration smoke into the bubble nozzle 4, so that the bubble nozzle 4 continuously and stably generates smoke bubbles 5; during the continuous increase of each smoke bubble 5, inject all the high-concentration smoke into the smoke bubble 5;

[0120] Use the air flow generated by the purging device 1 to blow across the periphery of the bubble nozzle 4 and act on the arc-shaped outer periphery of the smoke bubble 5 generated by the bubble nozzle 4, so that the bubble nozzle 4 continuously generates and separates floating smoke bubbles 5 and blows the floating smoke bubbles 5 away from the bubble nozzle 4; by changing the air flow speed of the purging device 1, adjust the separation speed and / or floating speed of the smoke bubbles 5; under the combined action of the air supply component 33 and the purging device 1, adjust the number and size of the floating smoke bubbles 5. In addition, the concentration of the high-concentration smoke can be adjusted, and the color (transparency) and density of the high-concentration smoke can be adjusted; the generation speed of the smoke bubbles can be adjusted by adjusting the output flow rate of the high-concentration smoke.

[0121] The process of generating smoke bubbles can be roughly divided into the following steps:

[0122] As Figure 13 shown, in the first step, the smoke bubbles on the bubble nozzle start to bulge;

[0123] As Figure 14 shown, in the second step, the smoke bubbles on the bubble nozzle gradually become larger;

[0124] As Figure 15 shown, in the third step, the smoke bubbles on the bubble nozzle continue to become larger, and under the combined action of the air supply component 33 and the purging device 1, the large smoke bubbles are about to split into small smoke bubbles;

[0125] As Figure 16 shown, in the fourth step, the small smoke bubbles have gradually moved away from the bubble nozzle and float in the environment;

[0126] As Figure 17 shown, in the fifth step, the smoke bubbles on the bubble nozzle gradually become larger, and continue to generate more smoke bubbles, and so on in a cycle.

[0127] In summary, the handheld smoke bubble system of the present utility model can not only generate smoke bubbles containing high-concentration smoke, but also the smoke bubbles are blown by the high-speed clean air flow generated by the purging device, so as to be separated from the bubble nozzle and released into the environment. The high-concentration smoke only exists inside the smoke bubbles, forming a more special atmosphere effect. Therefore, the present utility model effectively overcomes various disadvantages in the prior art and has high industrial utilization value.

[0128] The above embodiments are only illustrative of the principles and effects of the present utility model, and are not used to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present utility model should still be covered by the claims of the present utility model.
