Invention embodiment

Detailed ways

The present invention will be further described below in conjunction with specific embodiments and drawings.

As shown in Fig. 1, the continuous spray bubble machine is gun-shaped. 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 shown in Figure 2, the top of the bubble liquid bottle 2 is provided with a bubble liquid outlet 21. The bubble liquid outlet 21 is connected to the water inlet pipe 323 (see Figure 9) on the bubble forming mechanism 3 through a pipe (not shown), and the middle of the pipe is connected There is a lift pump (not shown) that pumps out the foaming water and delivers it to the water inlet pipe 323. When the lift pump is started, the bubble liquid bottle 2 supplies the foaming mechanism 3 with foaming water. The handle of the gun body 1 is provided with a first power supply cavity 11 for placing three batteries, and a lift pump is arranged at the rear of the gun body 1 so that the batteries in the first power supply cavity 11 provide power for it. The bubble liquid bottle 2 and the lifting pump are realized by using the existing technology, and the specific structure and principle thereof will not be repeated here.

As shown in Figure 3, the bubble-forming mechanism 3 includes a crank connecting rod structure 31, a bubble-out ring 32, a liquid wiper 33, and a housing 34. The housing 34 encloses an atomizing air path 35 (see Figure 4) and a bubble blowing air path 36. (See Figure 4). As shown in Figure 4, the back of the atomizing air path 35 and the blowing air path 36 in the housing 34 is provided with a gear transmission assembly 37. A double-head motor 38 is fixed next to the gear transmission assembly 37, and the first output shaft of the double-head motor 38 It is connected with the fan blade assembly 39 to form a fan. The fan blade assembly 39 is located at the rear end of the atomizing air path 35 and the blowing air path 36. When the double-head motor 38 drives the fan blade assembly 39 to rotate, the wind generated by the fan blade assembly 39 is removed from the fog. The rear ends of the air blowing path 35 and the blowing air path 36 enter the atomizing air path 35 and the blowing air path 36 respectively. The blowing wind road 36 is basically a straight wind road. The atomizing wind road 35 first walks to the right, then passes through the atomization module 4 and then turns left and merges with the blowing wind road 36, that is, the atomizing wind road 35 is a roundabout , And the atomizing air path 35 is narrower than the blowing air path 36, so the amount of air entering the atomizing air path 35 is smaller, so that the wind speed of the atomizing air path 35 is lower than the blowing air path 36. Since the atomizing air path 35 and the blowing air path 36 share a fan, and through the structural design of the atomizing air path 35 and the blowing air path 36, it can meet the different wind speeds of the atomizing air path 35 and the blowing air path 36. Upon request, the number of fans is reduced and the volume of the bubble machine is saved. The front end of the bubbling air path 36 and the atomizing air path 35 merge, so the wind generated by the fan blade assembly 39 passes through the atomizing air path 35 and the bubbling air path 36 respectively, and then merges to the bubbling ring 32 (see Figure 3). The smoke in the air path 35 is brought to the bubble-out ring 32, and then the smoke-laden wind continuously blows the liquid film at the bubble-out port 321 to continuously form smoke-enclosed bubbles to achieve continuous bubble generation.

The atomization air duct 35 is provided with an installation cavity 351 for detachably installing the atomization module 4 (see Figure 8), the atomization module 4 is installed in the installation cavity 351, and the installation cavity 351 is equipped with a cover 352 (see Figure 8). ), the cover 352 is fixed on the gun body 1 by screws. As shown in Figure 5, the atomization module 4 includes a housing 41, an atomization channel 42 and an atomization liquid container 43 (see Figure 6). The atomization channel 42 and the atomization liquid container 43 are both enclosed by the housing 41, but the atomization channel 42 The two ports are not covered by the housing 41, so that wind energy flows from one end of the atomization channel 42 to the other end. As shown in Figure 6, the atomization channel 42 is partially wrapped by the atomization liquid container 43, the atomization liquid container 43 is filled with the atomization liquid, and the part of the atomization channel 42 located in the atomization liquid container 43 has two opposite passages. Hole 421 (see Figure 7). There is a liquid absorbent cotton (not shown) in the atomization channel 42. The two ends of the liquid absorbent cotton respectively pass through the two through holes 421 and extend into the atomizing liquid container 43, so that the atomized liquid can be absorbed by the liquid absorbent cotton. It spreads and transmits along the two ends of the liquid absorbing cotton to the middle, so as to realize the supply of atomized liquid to the atomizing channel 42. After the two ends of the liquid absorbent cotton pass through the two through holes 421, the liquid absorbent cotton just fills the through holes 421, so that the atomized liquid in the atomized liquid container 43 can only enter the atomization channel 42 along the liquid absorbent cotton. Inside, the problem that the atomized liquid enters the atomization channel 42 too much and may leak from both ends of the atomization channel 42 is avoided. A heating wire (not shown) as a heating device is wound on the part of the liquid absorbent cotton located in the atomization channel 42, and a second power supply cavity 5 is provided above the crank connecting rod structure 31 in the gun body 1 (see Figure 2) , The battery installed in the second power supply cavity 5 supplies power to the heating wire (the structure and principle are described in detail below). As shown in Fig. 8, the gun body 1 includes an upper cover 12, and the upper cover 12 is fixed on the gun body 1 by screws. When the upper cover 12 is covered, the opening of the second power supply cavity 5 and the screw-locked part of the cover 352 of the installation cavity 351 are covered by the upper cover 12. After the upper cover 12 is opened, the opening of the second power supply chamber 5 is exposed, and the user can replace the battery. In addition, the screw-locked part of the cover 352 of the installation cavity 351 is also exposed. The user can remove the screw and open the cover 352 of the installation cavity 351, and then replace the atomization module 4. The installation cavity 351 is provided with a power supply contact 6 electrically connected to the battery in the second power supply cavity 5, and the atomization module 4 is provided with a power take-off contact 44 aligned with the power supply contact 6 in the installation cavity 351 (see Figure 5), The electrical 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 6 and the electric shock, so that the heating wire can be heated to atomize the atomizing liquid in the atomization channel 42 , The formation of smoke. In this embodiment, the atomized liquid container 43 realizes the packaging of the atomized liquid. The atomized liquid container 43 is provided with a liquid injection port 431 (see Figure 6), and the manufacturer fills the atomized liquid from the liquid injection port 431 Enter the atomized liquid container 43 and block the liquid injection port 431. After the atomized liquid module is manufactured, the housing 41 blocks the liquid injection port 431, so that the user cannot add the atomized 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, and the replaced atomization module 4 can be directly discarded. If the manufacturer needs it, it can also be recycled to the manufacturer for reuse.

In this embodiment, the atomized liquid container 43 realizes the encapsulation of the atomized liquid, and can also be changed to the housing 41 to realize the encapsulation of the atomized liquid, as long as the housing 41 isolates the atomized liquid from the user, and the housing 41 is not provided with The injection port of the atomized liquid can be injected so that the user cannot add the atomized liquid to the inside by himself.

In this embodiment, the part of the atomization channel 42 located in the atomization liquid container 43 has two opposite through holes. It can also be changed to have only one through hole 421, and a part of the liquid absorbent cotton passes through the through hole 421. It extends into the atomization liquid container 43 and the other part is in 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 absorbent cotton.

As shown in FIG. 2, the front end of the housing 34 is connected with a bubble liquid recovery member 7. The bubble liquid recovery member 7 includes a front shell 71 and a rear shell 72. The front shell 71 and the rear shell 72 enclose an accommodating space. The bubble liquid recovery member 7 has a structure for recovering bubble liquid. , I won’t repeat it here. The bubble outlet ring 32 and the liquid wiper 33 are arranged in the accommodating space, as shown in FIG. 9, a bubble outlet 321 is formed in the middle of the bubble outlet ring 32, and a main liquid flow channel 322 is provided above the front surface of the bubble outlet 321. The main liquid flow channel The lower end of 322 is connected to the front of the bubble outlet 321, and the upper end is connected to the water inlet pipe 323. The water inlet pipe 323 passes through the rear housing 72 and then connects to the lift pump through the pipe, and then connects to the bubble liquid bottle 2. The lift pump removes the bubble in the bubble liquid bottle 2. The bubble liquid is lifted and transported to the water inlet pipe 323. There is a gap between the front surface of the bubble ring 32 and the front housing 71, so that the bubble liquid can flow from the top to the bubble outlet 321 after entering the main liquid flow channel 322 from the water inlet pipe 323, and at the bubble outlet The front surface of the 321 forms a front liquid film. The outer wall of the upper half of the bubble ring 32 is provided with an outer wall axial liquid guide groove 324, and the inner wall of the bubble ring 32 is provided with a plurality of circumferential inner wall axial liquid guide grooves 325 densely distributed on the periphery of the bubble outlet 321, and each axial guide The two ends of the

liquid tanks

324 and 325 are respectively connected to the two 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 from the lower end of the main liquid channel 322 to the front can pass through the outer wall axial liquid guide groove 324 and the inner wall axial liquid guide groove 325 Flow to the back, it can be seen that the main liquid flow channel 322, the outer wall axial liquid guide groove 324, and the inner wall axial liquid guide groove 325 are used as liquid guide channels. The top of the liquid wiper 33 is rotatably fixed on the back of the bubble-out ring 32, the wiper 33 is connected with the transmission member 331, and the transmission member 331 is driven by the crank connecting rod structure 31 (see FIG. 3) to drive the wiper 33 Swing, so that the liquid wiping member 33 smears the bubble liquid on the back of the flow channel so that the back surface of the bubble outlet 321 forms a back liquid film. Since the bubble machine of this embodiment can form a liquid film on the front and back of the bubble outlet 321, and the front and back sides do not interfere with each other when the liquid film is formed, so long as either the front or back of the bubble outlet 321 is formed With the liquid film, the bubble can be formed, which increases the success rate of the bubble; since the liquid film can be formed on the front and the back, the bubble can be formed on the front and the liquid film can be formed on the back in time, so the bubble can be immediately bubbled on the back after the front is bubbled Continuity of bubbles.

As shown in FIG. 3, the crank connecting rod structure 31 includes a connecting rod 311 and a crank 312. The front end of the connecting rod 311 is fixed with a pair of pushing members 81 and 82 with a gap, and the transmission member 331 on the bubble outlet ring 32 passes through the rear housing 72 and is inserted into the gap. As shown in Figure 10, the edge of the crank 312 is provided with an insert block 3121, and the middle of the lower surface of the crank 312 is provided with a rotating shaft 3122. The rotating shaft 3122 passes through the housing 41 and connects to the tail transmission wheel 372 in the gear transmission assembly 37 (see Figure 4). Connected, the first transmission wheel 371 (see Figure 4) in the gear transmission assembly 37 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 internal gears are different from each other. The meshing relationship between them will not be repeated here. After the double-headed motor 38 is started, the gear transmission assembly 37 can drive the crank 312 to rotate. It can be seen that the double-headed motor 38 and the gear transmission assembly 37 are used as driving mechanisms. As shown in Figure 3, the rear end of the connecting rod 311 is provided with a moving through groove 3111, the insert block 3121 on the edge of the crank 312 is inserted into the moving through groove 3111, the top of the housing 41 is provided with a rotating fulcrum 45, and the middle of the connecting rod 311 is rotatable The ground is fixed on the rotating fulcrum 45. When the crank 312 rotates, the insert 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 rotation fulcrum 45, so that the front end of the connecting rod 311 swings back and forth. The pair of pushing members 81 and 82 swing back and forth with the front end of the connecting rod 311 to push the transmission member 331 together with the liquid wiper 33 to rotate back and forth, thereby realizing the liquid wiper 33 to swing back and forth. The position of the connecting rod 311 between the moving through groove 3111 and the middle part is provided with a limit groove 3112 parallel to the swing direction to limit the distance of the end of the connecting rod 311 swinging back and forth, thereby limiting the angle at which the liquid wiper 33 swings back and forth. , So that the liquid wiper 33 swings back and forth just to meet the requirement of coating the bubble liquid at the bubble outlet 321 to form a liquid film. This kind of bubble machine does not need a control program to control the rotation to realize the swing of the liquid wiper 33, which not only reduces the software development cost, but also reduces the volume at the bubble outlet 321 correspondingly.

In this embodiment, the outer wall axial liquid guide groove 324 is provided on the outer wall of the upper half of the bubble ring 32, and the inner wall of the bubble ring 32 is provided with a plurality of circumferential inner wall axial liquid guides densely distributed around the periphery of the bubble outlet 321 The two ends of each

axial guide groove

324 and 325 are respectively connected to the 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 flow channel 322 to the front can be The liquid guide groove 324 on the outer wall and the liquid guide groove 325 on the inner wall flow to the back, and then the liquid wiper 33 provided on the back of the bubble outlet 321 is oscillated to apply the bubble liquid flowing to the back of the bubble mouth 321. The back side of the film is formed on the backside liquid film. In a non-preferred case, the above-mentioned outer wall axial liquid guide groove 324 and inner wall axial liquid guide groove 325 can be changed to provide another main liquid flow channel that is the same as the main liquid flow channel 322 on the back of the bubble ring. The upper end of the main liquid flow channel 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 the bubble liquid can flow from the top to the bubble outlet 321 after entering the main liquid flow channel on the back from the water inlet pipe 323 , And form a back liquid film on the back of the bubble outlet 321. In this case, the liquid wiper 33, the crank connecting rod structure 31 and the gear transmission assembly 37 can be omitted, which has the advantage of a more streamlined structure. However, the prerequisite for using the main liquid flow channel on the back to flow down to the bubble outlet to form the back liquid film is that the main liquid flow channel needs to be above the bubble outlet. When the user uses the bubble machine, it is possible to hold it obliquely, so that the main liquid flow channel is not located above the bubble outlet. At this time, there is a risk that a liquid film cannot be formed at the bubble outlet, making the bubble machine Can not continue to bubble.

The above are only the preferred embodiments of the present invention. The present invention is not limited to the above-mentioned embodiments. There may be minor structural changes in the implementation process. If the various changes or modifications of the present invention do not depart from the spirit of the present invention Within the scope of the claims and equivalent technical scope of the present invention, the present invention also intends to include these changes and modifications.
