Description

Technical Field

[0001] The present invention relates to the field of entertainment appliances, and particularly to a bubble machine which can generate bubbles for use in stage cloth effects or for children to play with. Background Art

[0002] In order to be able to eject smoke bubbles, existing bubble machines are provided with an atomizing air path in addition to a blowing air path for blowing bubbles. Since a relatively large wind speed is required for blowing bubbles, and the wind speed for blowing smoke cannot be too large, otherwise it will affect the effect of the smoke generating component in the atomizing air path to generate smoke. Therefore, in the prior art, generally two blowers are respectively connected to the rear ends of the atomizing air path and the blowing air path to meet their different requirements for wind speed. Although the above-mentioned blower setting method can meet the basic requirements, it not only wastes blowers, but also makes the bubble machine large in size. Summary of the Invention

[0003] The present invention discloses a bubble machine which saves blowers and is small in size.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A bubble machine is provided with a blower, a blowing air path, an atomizing air path and a bubble outlet. The rear ends of the blowing air path and the atomizing air path are connected to the blower while the front ends are commonly connected to the bubble outlet. The rear ends of these two air paths are commonly connected to the same blower, and the atomizing air path is configured in the air path structure to have a lower wind speed than the blowing air path.

[0006] Further, the atomizing air path is narrower than the blowing air path so that the wind speed of the atomizing air path is lower than that of the blowing air path.

[0007] Further, the atomizing air path is circuitous so that the wind speed of the atomizing air path is lower than that of the blowing air path.

[0008] Further, an atomizing module is provided in the atomizing air path.

[0009] Further, an installation cavity for detachably installing the atomizing module is provided in the atomizing air path.

[0010] Further, it includes the atomizing module as described above.

[0011] Further, power supply contacts are provided in the installation cavity, and power-taking contact pieces aligned with the power supply contacts in the installation cavity are provided on the atomizing module.

[0012] Further, the atomizing module includes a housing, an atomizing channel for connecting between the blower and the bubble outlet, and an atomizing liquid container for supplying atomizing liquid into the atomizing channel. Both the atomizing channel and the atomizing liquid container are enclosed by the housing.

[0013] Further, the atomizing liquid container is filled with atomizing liquid.

[0014] Furthermore, a heating device is provided in the atomization channel to heat and atomize the atomization liquid in the atomization channel.

[0015] Furthermore, the atomization module includes a liquid-absorbing cotton. A part of the liquid-absorbing cotton is inside the atomization liquid container, and the other part is inside the atomization channel, so as to absorb the atomization liquid in the atomization liquid container and supply it to the atomization channel.

[0016] Furthermore, both ends of the liquid-absorbing cotton extend from both sides of the atomization channel into the atomization liquid container.

[0017] Furthermore, the heating device is a heating wire, and the heating wire is wound around the part of the liquid-absorbing cotton located in the atomization channel.

[0018] Furthermore, the outer shell and / or the atomization liquid container realize the encapsulation of the atomization liquid.

[0019] Furthermore, the atomization liquid container realizes the encapsulation of the atomization liquid. A liquid injection port is opened on the atomization liquid container, and the outer shell blocks the liquid injection port.

[0020] Beneficial effects: By connecting the same blower at the rear ends of the bubble blowing air path and the atomization air path, and setting the atomization air path to have a lower air speed than the bubble blowing air path in the air path structure, on the one hand, the number of blowers is reduced, and on the other hand, the volume of the bubble machine is saved while meeting the requirements of different air speeds for the atomization air path and the bubble blowing air path.

[0031] The present invention will be further described below in conjunction with specific embodiments and the accompanying drawings.

[0032] As Figure 1 , the continuous spraying bubble machine is in a gun shape, and the bubble machine includes a gun body 1, a bubble liquid bottle 2 with a bubble liquid cavity inside, and a bubble-forming mechanism 3 loaded in the gun body 1. As Figure 2 , a bubble liquid outlet 21 is provided at the top of the bubble liquid bottle 2, and the bubble liquid outlet 21 is connected to a water inlet pipe 323 (see Figure 9 ) on the bubble-forming mechanism 3 through a pipeline (not shown), and a lift pump (not shown) for pumping out and conveying the aerated water to the water inlet pipe 323 is connected in the middle of the pipeline. When the lift pump is started, the bubble liquid bottle 2 supplies aerated water to the bubble-forming mechanism 3. A first power supply cavity 11 for placing three batteries is provided inside the handle of the gun body 1, and the lift pump is arranged at the rear of the gun body 1 so that the batteries in the first power supply cavity 11 supply power to it. The bubble liquid bottle 2 and the lift pump are implemented by existing technologies, and their specific structures and principles will not be elaborated here.

[0033] As Figure 3 , the bubble-forming mechanism 3 includes a crank-link structure 31, a bubble-forming ring 32, a liquid-smearing member 33, and a housing 34. The housing 34 encloses an atomizing air path 35 (see Figure 4 ), a bubble-blowing air path 36 (see Figure 4 ). As Figure 4, there is a gear transmission assembly 37 provided at the back of the atomizing air path 35 and the bubble blowing air path 36 inside the housing 34. A double-headed motor 38 is fixed beside the gear transmission assembly 37. The first output shaft of the double-headed motor 38 is connected to the fan blade assembly 39 to form a blower. The fan blade assembly 39 is located at the rear ends of the atomizing air path 35 and the bubble blowing air path 36. When the double-headed motor 38 drives the fan blade assembly 39 to rotate, the wind generated by the fan blade assembly 39 enters the atomizing air path 35 and the bubble blowing air path 36 respectively from the rear ends of the atomizing air path 35 and the bubble blowing air path 36. The bubble blowing air path 36 is a basically straight air path. The atomizing air path 35 first goes to the right, then goes forward past the atomizing module 4 and turns left to converge with the bubble blowing air path 36. That is, the atomizing air path 35 is circuitous, and the atomizing air path 35 is narrower than the bubble blowing air path 36. Therefore, the air volume entering the atomizing air path 35 is smaller, making the wind speed in the atomizing air path 35 lower than that in the bubble blowing air path 36. Since the atomizing air path 35 and the bubble blowing air path 36 share a blower, and through the structural design of the atomizing air path 35 and the bubble blowing air path 36, while meeting the requirements of different wind speeds in the atomizing air path 35 and the bubble blowing air path 36, the number of blowers is reduced, saving the volume of the bubble machine. The bubble blowing air path 36 and the atomizing air path 35 converge at the front end. Therefore, the wind generated by the fan blade assembly 39 converges after passing through the atomizing air path 35 and the bubble blowing air path 36 respectively and reaches the bubble outlet ring 32 (see Figure 3 ). The smoke in the atomizing air path 35 is carried to the bubble outlet ring 32, and then the wind with smoke continuously blows up the liquid film at the bubble outlet 321 to continuously form bubbles wrapped with smoke, realizing continuous bubble blowing.

[0034] There is an installation cavity 351 for detachably installing the atomizing module 4 in the atomizing air path 35 (see Figure 8 ). The atomizing module 4 is installed in the installation cavity 351. The installation cavity 351 is equipped with a lid 352 (see Figure 8 ). The lid 352 is fixed to the gun body 1 by screws. As Figure 5 , the atomizing module 4 includes a housing 41, an atomizing channel 42 and an atomizing liquid container 43 (see Figure 6 ). The atomizing channel 42 and the atomizing liquid container 43 are both enclosed by the housing 41, but the two ports of the atomizing channel 42 are not covered by the housing 41, so that the wind can flow from one end of the atomizing channel 42 to the other end. As Figure 6 , the atomizing channel 42 is partially wrapped by the atomizing liquid container 43. The atomizing liquid container 43 contains atomizing liquid. Two opposite through holes 421 are opened at the part of the atomizing channel 42 located inside the atomizing liquid container 43 (see Figure 7)。There is a liquid absorbing cotton (not shown) inside the atomization channel 42. Both ends of the liquid absorbing cotton pass through two through holes 421 and extend into the atomization liquid container 43, so that the atomization liquid can be absorbed by the liquid absorbing cotton and spread along both ends of the liquid absorbing cotton to the middle for transmission, thereby realizing the supply of the atomization liquid to the atomization channel 42. After both ends of the liquid absorbing cotton pass through the two through holes 421 respectively, the liquid absorbing cotton just fills the through holes 421, so that the atomization liquid in the atomization liquid container 43 can only enter the atomization channel 42 along the liquid absorbing cotton, avoiding the problem that too much atomization liquid enters the atomization channel 42 and may leak from both ends of the atomization channel 42. A heating wire (not shown) serving as a heating device is wound around the part of the liquid absorbing cotton located inside the atomization channel 42. Inside the gun body 1, a second power supply cavity 5 is arranged above the crank connecting rod structure 31 (see Figure 2 ). The battery installed in the second power supply cavity 5 supplies power to the heating wire (its structure and principle will be described in detail below). As Figure 8 , the gun body 1 includes an upper cover 12, and the upper cover 12 is fixed to the gun body 1 by screws. When the upper cover 12 is closed, the opening of the second power supply cavity 5 and the part of the lid 352 of the installation cavity 351 locked by the screws are covered by the upper cover 12. After the upper cover 12 is opened, the opening of the second power supply cavity 5 is exposed, and the user can replace the battery. In addition, the part of the lid 352 of the installation cavity 351 locked by the screws is also exposed, and the user can remove the screws and then open the lid 352 of the installation cavity 351, and then replace the atomization module 4. A power supply contact point 6 electrically connected to the battery in the second power supply cavity 5 is arranged in the installation cavity 351, and a power taking contact piece 44 aligned with the power supply contact point 6 in the installation cavity 351 is arranged on the atomization module 4 (see Figure 5 ), and the power taking contact piece 44 is electrically connected to the heating wire. When the atomization module 4 is installed in the installation cavity 351, the battery in the second power supply cavity 5 supplies power to the heating wire through the power supply contact point 6 and the power taking contact, so that the heating wire can heat to atomize the atomization liquid in the atomization channel 42 to form smoke. In this embodiment, the atomization liquid container 43 realizes the encapsulation of the atomization liquid. A liquid injection port 431 is opened on the atomization liquid container 43 (see Figure 6 ). The manufacturer fills the atomization liquid into the atomization liquid container 43 from the liquid injection port 431 and blocks the liquid injection port 431. After the atomization liquid module is manufactured, the outer shell 41 blocks the liquid injection port 431, so that the user cannot add the atomization liquid by himself to ensure safety. If the atomization liquid is used up, the user only needs to replace the atomization module 4 as a whole. The replaced atomization module 4 can be directly discarded. If the manufacturer has a need, it can also be recycled by the manufacturer for reuse.

[0035] In this embodiment, the atomization liquid container 43 realizes the encapsulation of the atomization liquid, and it can also be changed to the outer shell 41 to realize the encapsulation of the atomization liquid, as long as the outer shell 41 isolates the atomization liquid from the user and no injection port for injecting the atomization liquid is provided on the outer shell 41, so that the user cannot add the atomization liquid into it by himself.

[0036] In this embodiment, two opposite through holes are formed in the part of the atomization channel 42 located inside the atomization liquid container 43. It can also be changed to only one through hole 421. A part of the liquid absorption cotton passes through the through hole 421 and extends into the atomization liquid container 43, and the other part is inside the atomization channel 42, as long as the atomization liquid in the atomization liquid container 43 can spread to the atomization channel 42 through the liquid absorption cotton.

[0037] Such as Figure 2 , a bubble liquid recovery member 7 is connected to the front end of the housing 34. The bubble liquid recovery member 7 includes a front housing 71 and a rear housing 72. The front housing 71 and the rear housing 72 enclose an accommodation space. The structure of the bubble liquid recovery member 7 for recovering bubble liquid is prior art and will not be elaborated here. The bubble outlet ring 32 and the liquid wiping member 33 are arranged in the accommodation space. Such as Figure 9 , a bubble outlet 321 is formed in the middle of the bubble outlet ring 32. A main liquid flow channel 322 is provided above the front of the bubble outlet 321. The lower end of the main liquid flow channel 322 is connected to the front of the bubble outlet 321, and the upper end is connected to a water inlet pipe 323. The water inlet pipe 323 passes through the rear housing 72 and is connected to a lifting pump through a pipeline and then to a bubble liquid bottle 2. The lifting pump lifts and transports the bubble liquid in the bubble liquid bottle 2 to the water inlet pipe 323. A gap is left between the front of the bubble outlet ring 32 and the front housing 71, so that after the bubble liquid enters the main liquid flow channel 322 from the water inlet pipe 323, it can flow from top to bottom to the bubble outlet 321 and form a front liquid film on the front of the bubble outlet 321. An outer wall axial liquid guiding groove 324 is formed on the outer wall of the upper half ring of the bubble outlet ring 32, and a plurality of inner wall axial liquid guiding grooves 325 densely arranged in a surrounding manner along the circumference of the bubble outlet 321 are formed on the inner wall of the bubble outlet ring 32. Both ends of each axial liquid guiding groove 324 and 325 are respectively connected to both sides of the bubble outlet 321. The top of the bubble outlet ring 32 is inclined backward, so that the front of the bubble outlet 321 is higher than the back, so that the bubble liquid flowing down from the lower end of the main liquid flow channel 322 to the front can flow to the back through the outer wall axial liquid guiding groove 324 and the inner wall axial liquid guiding groove 325. It can be seen that the main liquid flow channel 322, the outer wall axial liquid guiding groove 324 and the inner wall axial liquid guiding groove 325 are used as liquid flow channels. The top of the liquid wiping member 33 is rotatably fixed on the back of the bubble outlet ring 32. The liquid wiping member 33 is connected to a transmission member 331. The transmission member 331 drives the liquid wiping member 33 to swing under the drive of the crank connecting rod structure 31 (see Figure 3 ), so that the liquid wiping member 33 smears the bubble liquid on the back of the flow channel to form a back liquid film on the back of the bubble outlet 321. Since the bubble machine in this embodiment can form liquid films on both the front and the back of the bubble outlet 321, and the front and the back are basically not interfered with each other when forming the liquid films, as long as a liquid film is formed on either the front or the back of the bubble outlet 321, foaming can occur, improving the foaming success rate; since liquid films can be formed on both the front and the back, and the back can form a liquid film in time while the front is foaming, so bubbles can be immediately formed on the back after the front bubbles, improving the bubble continuity.

[0038] As Figure 3 , the crank - connecting rod structure 31 includes a connecting rod 311 and a crank 312. A pair of pushing members 81, 82 with a gap are fixed at the front end of the connecting rod 311. The transmission member 331 on the bubble - forming ring 32 passes through the rear housing 72 and is inserted into the gap. As Figure 10 , an insertion block 3121 is provided at the edge of the crank 312, and a rotating shaft 3122 is provided in the middle of the lower surface of the crank 312. The rotating shaft 3122 passes through the outer housing 41 and is connected to the tail transmission wheel 372 in the gear transmission assembly 37 (see Figure 4 ), and the head transmission wheel 371 in the gear transmission assembly 37 (see Figure 4 ) meshes with the screw 9 provided on the second output shaft of the double - headed motor 38. The gear transmission assembly 37 is a prior art, and the meshing relationship between its internal gears will not be elaborated here. After the double - headed motor 38 is started, it can drive the crank 312 to rotate through the gear transmission assembly 37. Thus, it can be seen that the double - headed motor 38 and the gear transmission assembly 37 are used as a driving mechanism. As Figure 3 , a moving through - slot 3111 is provided at the rear end of the connecting rod 311. The insertion block 3121 on the edge of the crank 312 is inserted into the moving through - slot 3111. A rotating fulcrum 45 is provided at the top of the outer housing 41, and the middle part of the connecting rod 311 is rotatably fixed on the rotating fulcrum 45. When the crank 312 rotates, the insertion block 3121 pushes the rear end of the connecting rod 311 to swing, and the middle part of the connecting rod 311 rotates around the rotating fulcrum 45, so that the front end of the connecting rod 311 swings back and forth. A pair of pushing members 81, 82 swing back and forth with the front end of the connecting rod 311 to push the transmission member 331 and the liquid - wiping member 33 to rotate back and forth, so as to realize the back - and - forth swing of the liquid - wiping member 33. A limiting slot 3112 parallel to the back - and - forth swing direction is provided at the position of the connecting rod 311 between the moving through - slot 3111 and the middle part to limit the distance of the back - and - forth swing of the end of the connecting rod 311, thereby limiting the angle of the back - and - forth swing of the liquid - wiping member 33, so that the back - and - forth swing of the liquid - wiping member 33 just meets the requirement of coating bubble liquid at the bubble outlet 321 to form a liquid film. This kind of bubble machine can realize the swing of the liquid - wiping member 33 without the need of a control program to control the rotation, which can not only reduce the software development cost, but also correspondingly reduce the volume at the bubble outlet 321.

[0039] In this embodiment, an outer wall axial liquid guiding groove 324 is formed on the outer wall of the upper half ring of the bubble outlet ring 32, and a plurality of inner wall axial liquid guiding grooves 325 densely arranged in a surrounding manner along the periphery of the bubble outlet 321 are formed on the inner wall of the bubble outlet ring 32. Both ends of each axial liquid guiding groove 324 and 325 are respectively connected to two sides of the bubble outlet 321, and the top of the bubble outlet ring 32 is inclined backward, so that the bubble liquid flowing down from the lower end of the main liquid guiding channel 322 to the front can flow to the back through the outer wall axial liquid guiding groove 324 and the inner wall axial liquid guiding groove 325, and then the wiping member 33 arranged on the back of the bubble outlet 321 swings to smear the bubble liquid flowing to the back, thereby forming a back liquid film on the back of the bubble outlet 321. In a non-preferred case, the above-mentioned outer wall axial liquid guiding groove 324 and inner wall axial liquid guiding groove 325 can also be changed to another main liquid guiding channel identical to the main liquid guiding channel 322 arranged on the back of the bubble outlet ring. The upper end of the main liquid guiding channel on the back is also connected to the water inlet pipe 323, and its lower end is connected to the back of the bubble outlet 321, so that after the bubble liquid enters the main liquid guiding channel on the back from the water inlet pipe 323, it can flow downward to the bubble outlet 321 and form a back liquid film on the back of the bubble outlet 321. In this case, the wiping member 33, the crank connecting rod structure 31 and the gear transmission assembly 37 can be omitted, which has the advantage of more concise structure. However, the prerequisite for forming a back liquid film by flowing downward through the main liquid guiding channel on the back to the bubble outlet is that the main liquid guiding channel needs to be above the bubble outlet. When the user holds the bubble machine obliquely during use, the main liquid guiding channel may not be above the bubble outlet, and at this time, there is a risk that a liquid film cannot be formed at the bubble outlet, resulting in the inability of the bubble machine to continuously produce bubbles.

[0040] The above is only the preferred embodiment of the present invention. The present invention is not limited to the above embodiment. There may be minor structural changes during the implementation process. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention and belong to the scope of the claims of the present invention and equivalent technical scope, then the present invention also intends to include these changes and modifications.
