Smoke collecting box and smoke bubble machine

Abstract

The utility model relates to a smoke collecting box and a smoke bubble machine. The smoke collecting box is provided with an inlet and an outlet. A channel is formed in the smoke collecting box and communicated between the inlet and the outlet. The channel comprises at least one bent section, so that the length of the channel is larger than the linear distance between the inlet and the outlet. On the premise that the size of the smoke collecting box is fixed, as the channel comprises at least one bent section, smoke at an inlet can be prevented from flowing to an outlet along a straight line, and the length of the channel is increased. Due to the fact that the length of the channel is increased, the flowing time of the smoke in the channel is prolonged, the opportunity that tobacco tar particles are attached to the inner wall face of the smoke collecting box is increased, the content of the tobacco tar particles in the discharged smoke can be reduced, a porous filtering structure does not need to be arranged near the outlet, and smoke blocking caused by the porous filtering structure is avoided. Therefore, the smoke collecting box has stable smoke output efficiency.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bubble blowing devices, in particular to a smoke collecting box and a smoke bubble machine. BACKGROUND

[0002] The smoke bubble machine is a machine that can be used to generate bubbles, and the bubbles generated by the machine are filled with smoke, which can not only be used for daily entertainment, but also can be used to create a certain atmosphere for the stage.

[0003] The smoke bubble machine generally generates smoke by atomizing and heating tobacco oil. After the smoke is preliminarily cooled in the collecting box, the smoke is used to blow the bubble film. During the atomization and heating process, a part of the tobacco oil is not atomized and forms tobacco oil particles, which are mixed in the smoke. The tobacco oil particles will affect the bubbles, for example, they can increase the internal pressure of the bubbles, causing the bubbles to be more likely to break, and reducing the time for the bubbles to float in the air

[0004] In the conventional technology, a porous filter structure similar to a sponge is generally arranged near the outlet of the collecting box to filter the tobacco oil in the smoke. However, after a long time of use, the porous filter structure is easily blocked by the attachment of the tobacco oil, causing the smoke to be difficult to pass through, which affects the output efficiency of the smoke. CONTENT OF THE INVENTION

[0005] Therefore, the present application provides a smoke collecting box and a smoke bubble machine that can solve or at least alleviate the above technical problems.

[0006] The present application provides a smoke collecting box applied to a smoke bubble machine, wherein the smoke collecting box is provided with an inlet and an outlet; a channel is formed inside the smoke collecting box; the channel is communicated between the inlet and the outlet; and the channel includes at least one bending section, so that the length of the channel is greater than the straight-line distance between the inlet and the outlet.

[0007] In the application, the smoke generated by the atomization of the tobacco oil enters the smoke collecting box from the inlet. Then, the smoke flows along the channel until it reaches the outlet. After the smoke flows out of the smoke collecting box from the outlet, it is used to blow the bubble film to generate bubbles filled with smoke. Under the premise that the volume of the smoke collecting box is constant, the length of the channel is increased due to the at least one bending section, which prevents the smoke at the inlet from flowing to the outlet along a straight line. The length of the channel is increased, which prolongs the time for the smoke to flow in the channel and increases the opportunity for the tobacco oil particles to attach to the inner wall of the smoke collecting box, thereby reducing the content of the tobacco oil particles in the discharged smoke. Therefore, it is not necessary to arrange a porous filter structure near the outlet, which avoids the blockage of the porous filter structure by the smoke, so that the smoke collecting box has a stable smoke output efficiency.

[0008] In one embodiment, the device comprises a housing and at least one partition accommodated in the housing; the at least one partition is arranged between the inlet and the outlet; the housing and the at least one partition jointly define the channel.

[0009] In one embodiment, the at least one partition comprises a plurality of partitions, which are linearly spaced apart.

[0010] In one embodiment, the bending section of the channel passes between one end of a partition and an inner wall surface of the housing, or the bending section of the channel penetrates a partition.

[0011] In one embodiment, the inner side of the housing has a bottom surface; in a predetermined installation state, the height of the bottom surface near one side of the inlet is lower than the height of the bottom surface far from the inlet.

[0012] In one embodiment, the channel comprises at least two straight sections; a bending section is arranged between two straight sections; two straight sections connected to the same bending section are arranged in parallel.

[0013] In one embodiment, a straight section has opposite first and second ends, the first end is closer to the outlet than the second end, and the second end is closer to the inlet than the first end; in a predetermined installation state, the height of the first end is lower than the height of the second end.

[0014] In one embodiment, in a predetermined installation state, the height of the inlet is lower than the height of the outlet.

[0015] In one embodiment, the bending section is in an arc shape, a polyline shape, or a spiral shape.

[0016] The utility model provides a smoke bubble machine, including the smoke collection box of any one embodiment above. BRIEF DESCRIPTION OF DRAWINGS

[0031] The technical solutions provided by the embodiments of the present application will be described below with reference to the drawings.

[0032] In combination with Figure 1 and Figure 2 , the present application provides a smoke bubble machine 100. Specifically, the smoke bubble machine 100 combines the effects of smoke and bubbles, and can be used in stage performances, weddings, celebrations and the like to create a certain visual effect. Specifically, the bubbles output by the smoke bubble machine 100 are filled with smoke.

[0033] Specifically, in combination with Figure 3a and Figure 3b , the smoke bubble machine 100 includes a heater 20 and a smoke collection box 30. The heater 20 is used to heat the tobacco tar to atomize the tobacco tar and generate smoke. The smoke collection box 30 is used to collect the smoke. After the smoke is discharged from the smoke collection box 30, it can reach the position where the bubble film is formed. When the bubble film gradually forms a bubble under the action of the pressure difference, the smoke flows into the bubble, so that the bubble is filled with smoke.

[0034] Optionally, in combination with Figure 1As shown, the smoke bubble machine 100 further comprises a film forming nozzle 21 and a film brushing body 22. The film brushing body 22 is movably arranged relative to the film forming nozzle 21. When the film brushing body 22 is moved relative to the film forming nozzle 21, the film brushing body 22 can cause the bubble liquid to form a bubble film at the port of the film forming nozzle 21. Further, the smoke bubble machine 100 further comprises a liquid storage body 23. The liquid storage body 23 is configured to store the bubble liquid. Optionally, the film forming nozzle 21 and the liquid storage body 23 are connected by a liquid delivery pipe to guide the bubble liquid in the liquid storage body 23 to flow to the film forming nozzle 21.

[0035] Optionally, in combination with Figure 3a and Figure 4 As shown, the smoke bubble machine 100 further comprises a first air flow driving member 24. The first air flow driving member 24 is configured to suck the smoke from the smoke collecting box 30 and drive the smoke to flow to the position where the bubble film is formed. Specifically, the first air flow driving member 24 can be a fan. Specifically, the smoke flows to the film forming nozzle 21.

[0036] Optionally, in combination with Figure 3a and Figure 5 As shown, the smoke bubble machine 100 further comprises a liquid storage body 23. The liquid storage body 23 is configured to store the bubble liquid. Optionally, the film forming nozzle 21 and the liquid storage body 23 are connected by a liquid delivery pipe to guide the bubble liquid in the liquid storage body 23 to flow to the film forming nozzle 21.

[0037] Optionally, in combination with Figure 3b and Figure 4 As shown, the smoke bubble machine 100 further comprises a second air flow driving member 27. The second air flow driving member 27 is configured to generate an air flow to drive the generated bubble to float away from the smoke bubble machine 100 to avoid the bubble to accumulate and collide near the smoke bubble machine 100. In some embodiments, the second air flow driving member 27 is a fan. The smoke bubble machine 100 further comprises an air flow duct 271 connected to the second air flow driving member 27. The air flow duct 271 is configured to adjust the flow direction of the air flow generated by the second air flow driving member 27.

[0038] Optionally, in combination with Figure 2 As shown, the smoke bubble machine 100 comprises a machine housing 28. The heater 20, the smoke collecting box 30, the film forming nozzle 21, the liquid storage body 23, the first air flow driving member 24 and the second air flow driving member 27 are all or partially installed in the machine housing 28.

[0039] In some embodiments, in combination with Figure 2As shown, the smoke bubble machine 100 has a first reference direction F1. In use of the smoke bubble machine 100, the smoke bubble machine 100 is placed on a bearing surface in a normal use state, the first reference direction F1 is substantially perpendicular to the bearing surface. Optionally, the casing 28 has a bottom side, and a plurality of leg members 281 are connected to the bottom side of the casing 28. In the normal use state, the casing 28 is supported on the plurality of leg members 281.

[0040] Optionally, in combination with any of the above embodiments, Figure 3a and Figure 6 As shown, the smoke collection box 30 has a predetermined installation state relative to the casing 28 or other support structure. In the predetermined installation state, the first reference direction F1 of the smoke bubble machine 100 is substantially in the same direction as the vertical downward direction, and the smoke collection box 30 has a determined direction relative to the casing 28 or other support structure, so that the smoke collection box 30 has a determined relative height relationship between the various parts. More specifically, the smoke collection box 30 has a second reference direction F2, which is substantially in the same direction as the first reference direction F1.

[0041] In combination with any of the above embodiments, Figures 6 to 9 As shown, the present application also provides a smoke collection box 30, which can be applied to at least the smoke bubble machine 100 in any of the above embodiments. The smoke collection box 30 is provided with an inlet 301 and an outlet 302. A channel 31 is formed inside the smoke collection box 30, and the channel 31 is communicated between the inlet 301 and the outlet 302. The channel 31 includes at least one bending section 311, so that the length of the channel 31 is greater than the straight-line distance between the inlet 301 and the outlet 302.

[0042] In application, the smoke collection box 30 of the present application is used to collect the smoke generated by atomization of the smoke oil. The smoke flows along the channel 31 until reaching the outlet 302. After the smoke flows out of the smoke collection box 30 from the outlet 302, it is used to blow the bubble film to generate bubbles filled with smoke. Under the premise of a certain volume of the smoke collection box 30, the length of the channel 31 is increased due to the at least one bending section 311, so that the smoke at the inlet 301 is prevented from flowing to the outlet 302 in a straight line. The length of the channel 31 is increased, so that the time for the smoke to flow in the channel 31 is prolonged, and the opportunity for the smoke oil particles to adhere to the inner wall of the smoke collection box 30 is increased, thereby reducing the content of the smoke oil particles in the discharged smoke. The porous filtering structure does not need to be arranged near the outlet 302, the porous filtering structure is avoided to cause the smoke to be blocked, and the smoke collection box 30 has a stable smoke output efficiency.

[0043] Understandably, after the length of the channel 31 is increased, the time for the smoke to flow in the channel 31 is prolonged, so that the time for the smoke to be cooled down is correspondingly increased, so that the smoke discharged from the outlet 302 of the smoke collecting box 30 can be lowered to a suitable temperature, avoiding that other components of the bubble machine 100 are damaged due to the smoke being too hot, and avoiding that the formation of bubbles is affected due to the smoke being too hot.

[0044] Understandably, compared with the smoke collecting box 30 having a cavity between the inlet 301 and the outlet 302, the smoke collecting box 30 of the present application can make the smoke orderly flow to the outlet 302 after entering, avoiding that the high-temperature smoke and the cooled smoke are alternately discharged from the outlet 302 in disorder, and being beneficial to guarantee the uniformity of the temperature of the discharged smoke.

[0045] Optionally, in combination with the smoke collecting box 30 shown in Figure 6 and Figure 7 , in the predetermined installation state, the height of the inlet 301 is lower than the height of the outlet 302, on the one hand, the tobacco tar focused on the boundary surface of the channel 31 can flow to the vicinity of the inlet 301 under the action of gravity, which is beneficial to the recycling of the tobacco tar, and on the other hand, since the outlet 302 has a relatively high height, the focused tobacco tar can be avoided from blocking the outlet 302, so as to guarantee the smoke output efficiency of the smoke collecting box 30. Understandably, along the second reference direction F2, the inlet 301 is downstream relative to the outlet 302.

[0046] Optionally, in the predetermined installation state, the height of the inlet 301 is close to or consistent with the height of the outlet 302.

[0047] Optionally, the bending section 311 is in an arc shape, a polyline shape or a spiral shape. Understandably, after passing through the bending section 311, the flow direction of the smoke is changed. Optionally, the channel 31 includes a plurality of bending sections 311 which are sequentially communicated. The two bending sections 311 which are communicated can adopt the same shape or different shapes.

[0048] In some embodiments, in combination with the smoke collecting box 30 shown in Figure 8 , the channel 31 includes at least two straight sections 312. The bending section 311 is communicated and arranged between the two straight sections 312. Optionally, the bending section 311 can be communicated to the inlet 301 through one straight section 312. Optionally, the bending section 311 can be communicated to the outlet 302 through one straight section 312. Optionally, one bending section 311 can be communicated to another bending section 311 through one straight section 312.

[0049] In some embodiments, in combination with the smoke collecting box 30 shown in Figure 8As shown, for two straight line segments 312 connected to the same bending segment 311, the two straight line segments 312 are arranged in parallel, so as to facilitate the two straight line segments 312 to have uniform interval size, and to reduce the space occupied by the two straight line segments 312 as a whole, so as to make full use of the internal space of the smoke collection box 30, and to facilitate further increase of the length of the passage 31.

[0050] In some embodiments, the straight line segments 312 are arranged in parallel. Figure 8 As shown, the straight line segments 312 have opposite first ends 313 and second ends 314. Along the predetermined flow direction of the smoke in the passage 31, the first ends 313 are closer to the outlet 302 than the second ends 314, and the second ends 314 are closer to the inlet 301 than the first ends 313. Understandably, when the smoke flows in the passage 31, the smoke first passes through the second ends 314 of the straight line segments 312, and then passes through the first ends 313 of the straight line segments 312.

[0051] Optionally, the straight line segments 312 are arranged in parallel. Figure 8 As shown, in the predetermined installation state of the smoke collection box 30, the height of the first ends 313 of the straight line segments 312 is lower than the height of the second ends 314 of the straight line segments 312, and after the smoke oil particles are focused on the boundary surface of the straight line segments 312 to form flowable smoke oil, the straight line segments 312 can guide the smoke oil to flow in the direction from the first ends 313 to the second ends 314, so that the smoke oil gradually flows to the position close to the inlet 301. Further, the smoke collection box 30 has an oil outlet 323 arranged near the inlet 301, and the oil outlet 323 is used to discharge the smoke oil flowing to the position close to the inlet 301. The oil outlet 323 is connected to the oil storage tank 25 through an oil delivery pipe, so that the smoke oil collected in the smoke collection box 30 can be reused, thereby reducing the consumption of the smoke oil. Understandably, along the second reference direction F2, the second ends 314 are downstream of the first ends 313.

[0052] Specifically, the straight line segments 312 are arranged in parallel. Figure 7 and Figure 8 As shown, in the predetermined installation state, the height of the lower edge of the inlet 301 is higher than the height of the oil outlet 323, so as to avoid leakage of the smoke oil from the inlet 301. Understandably, along the second reference direction F2, the oil outlet 323 is downstream of the lower edge of the inlet 301. Optionally, the height of the oil outlet 323 is higher than the liquid level of the smoke oil in the oil storage tank 25, so that the smoke oil in the smoke collection box 30 can flow to the oil storage tank 25 under the action of gravity.

[0053] Optionally, the smoke bubble machine 100 further comprises an oil pump 26 connected between the oil outlet 323 and the oil storage tank 25, and the oil pump 26 generates fluid pressure to make the smoke oil in the smoke collection box 30 flow to the oil storage tank 25.

[0054] Exemplarily, the straight line segments 312 are arranged in parallel. Figure 9As shown, in at least two adjacent straight segments 312, the volume of the straight segment 312 farther away from the inlet 301 is larger than that of the straight segment 312 closer to the inlet 301. For example, starting from the straight segment 312 closer to the inlet 301, the height of the last straight segment 312 is much larger than that of the first straight segment 312, while the width and length of the two are substantially the same. In some embodiments, the smoke collection box 30 has three straight segments 312, starting from the straight segment 312 closer to the inlet 301, the height of the three straight segments 312 increases successively. The last straight segment 312 is connected to the outlet 302 and has a higher height range, thereby facilitating the docking of the outlet 302 with the suction end of the first airflow driving member 24.

[0055] In some embodiments, in combination with Figure 8 and Figure 9 As shown, the smoke collection box 30 comprises a housing 32 and at least one partition 33 accommodated in the housing 32. The inlet 301 and the outlet 302 are arranged on the housing 32. The at least one partition 33 is arranged between the inlet 301 and the outlet 302 to limit the flow of smoke at the inlet 301 to the outlet 302 in a straight line. The housing 32 and the at least one partition 33 jointly define the channel 31. Specifically, with the volume of the housing 32 being constant, by arranging the partition 33 in the housing 32, the distance between the opposite walls inside the smoke collection box 30 can be reduced while forming the channel 31. After the distance between the opposite walls is reduced, when the smoke passes between the opposite walls, the opportunity for the tar particles to adhere to the walls can be increased, thereby more effectively reducing the content of tar particles in the smoke.

[0056] Specifically, in combination with Figure 8 and Figure 9 As shown, the housing 32 forms part of the boundary of the channel 31, thereby reducing the number of partitions 33 and facilitating the reduction of the cost of the smoke collection box 30. Specifically, in the predetermined installation state, the inlet 301 can be arranged on the horizontal side of the housing 32 or on the bottom side of the housing 32. Specifically, the outlet 302 can be arranged on the horizontal side of the housing 32 or on the top side of the housing 32. In other embodiments, the boundary of the channel 31 can also be formed entirely by the partitions 33 in the housing 32.

[0057] In some embodiments, in combination with Figure 8As shown, the bending section 311 of the channel 31 passes between one end of the partition 33 and the inner wall surface 322 of the housing 32. Specifically, the partition 33 has a first edge 331 and a second edge 332. The distance between the first edge 331 and the housing 32 is greater than the distance between the second edge 332 and the housing 32. The first edge 331 and the housing 32 define the bending section 311, i.e., the bending section 311 of the channel 31 passes between one end of the partition 33 and the inner wall surface 322 of the housing 32. Alternatively, the second edge 332 is integrally connected with the housing 32. Alternatively, the second edge 332 is sealingly abutted with the inner wall surface 322 of the housing 32. Alternatively, the second edge 332 can be spaced apart from the inner wall surface 322 of the housing 32.

[0058] In some embodiments, the bending section 311 of the channel 31 penetrates the partition 33. Understandably, the partition 33 has a through hole formed thereon, and the inner edge of the through hole simultaneously serves as the boundary of the bending section 311.

[0059] Alternatively, the housing 32 contains one partition 33. Further, with respect to the connecting straight line between the inlet 301 and the outlet 302, the bending section 311 of the corresponding partition 33 is located outside the connecting straight line. The distance between the bending section 311 and the connecting straight line is close to the horizontal width of the housing 32, which can effectively increase the length of the channel 31.

[0060] Alternatively, in combination with Figure 8 As shown, the housing 32 contains a plurality of partitions 33. The plurality of partitions 33 are linearly spaced apart. Specifically, the internal space of the housing 32 is divided by the plurality of partitions 33, which can effectively increase the overall length of the channel 31 and effectively reduce the distance between the internal opposite wall surfaces. Alternatively, in the predetermined installation state, the linear distribution direction between the plurality of partitions 33 is substantially parallel to the horizontal direction. Alternatively, in the predetermined installation state, the linear distribution direction between the plurality of partitions 33 is substantially parallel to the vertical direction. Understandably, the plurality of partitions 33 are substantially perpendicular to the second reference direction F2, or the plurality of partitions 33 are substantially parallel to the second reference direction F2.

[0061] In some embodiments, in combination with Figure 8 As shown, the straight section 312 is formed between two adjacent and opposite partitions 33. Alternatively, in the predetermined installation state, the two opposite partitions 33 along the horizontal direction respectively form the horizontal boundaries on both sides of the straight section 312, and the inner wall surface 322 of the housing 32 forms the upper boundary and the lower boundary of the straight section 312. Alternatively, in the predetermined installation state, the two opposite partitions 33 along the vertical direction respectively form the upper boundary and the lower boundary on both sides of the straight section 312, and the inner wall surface 322 of the housing 32 forms the horizontal boundary of the straight section 312.

[0062] In some embodiments, the first edge 331 of the partition 33 is arranged to be opposite to the first edge 331 of the adjacent partition 33, so that the distance between the two adjacent partitions 33 is greater than the distance between the two adjacent partitions 33, and the length of the channel 31 is increased. Figure 8 In some embodiments, the first edge 331 of the partition 33 is arranged to be opposite to the first edge 331 of the adjacent partition 33, so that the distance between the two adjacent partitions 33 is greater than the distance between the two adjacent partitions 33, and the length of the channel 31 is increased.

[0063] In some embodiments, three partitions 33 arranged in sequence are referred to as a first partition, a second partition and a third partition. The first edge 331 of the first partition and the first edge 331 of the third partition are connected to a part of the inner wall surface 322 of the housing 32. The first edge 331 of the second partition is arranged to be spaced apart from the part of the inner wall surface 322 of the housing 32. Understandably, a bending section 311 is located between the first partition and the third partition, and the bending section 311 also passes between the part of the inner wall surface 322 of the housing 32 and the first edge 331 of the second partition. More specifically, before passing through the bending section 311, the flow direction of the smoke is parallel to the second partition and towards the part of the inner wall surface 322 of the housing 32. After passing through the bending section 311, the flow direction of the smoke is parallel to the second partition and away from the part of the inner wall surface 322 of the housing 32.

[0064] In some embodiments, the first edge 331 of the partition 33 is arranged to be opposite to the first edge 331 of the adjacent partition 33, so that the distance between the two adjacent partitions 33 is greater than the distance between the two adjacent partitions 33, and the length of the channel 31 is increased.

[0065] In some embodiments, the first edge 331 of the partition 33 is arranged to be opposite to the first edge 331 of the adjacent partition 33, so that the distance between the two adjacent partitions 33 is greater than the distance between the two adjacent partitions 33, and the length of the channel 31 is increased.

[0066] Optionally, the shape of the partition 33 can be regular or irregular. Specifically, the regular shape includes but is not limited to a rectangle and an arc. Optionally, when the number of partitions 33 is at least two, the shape of each partition 33 can be the same or different.

[0067] In some embodiments, the first edge 331 of the partition 33 is arranged to be opposite to the first edge 331 of the adjacent partition 33, so that the distance between the two adjacent partitions 33 is greater than the distance between the two adjacent partitions 33, and the length of the channel 31 is increased. Figure 8 and Figure 9As shown, the inner side of the outer casing 32 has a bottom surface 321. In the predetermined installation state, the height of the side of the bottom surface 321 near the inlet 301 is lower than the height of the side of the bottom surface 321 away from the inlet 301. Specifically, when e-liquid particles focus at the boundary surface of the straight segment 312 to form flowable e-liquid, under the action of gravity, the bottom surface 321 of the outer casing 32 can guide the e-liquid to gradually flow to the position near the inlet 301, thereby facilitating the collection and reuse of e-liquid. Understandably, along the second reference direction F2, the side of the bottom surface 321 near the inlet 301 is downstream of the side of the bottom surface 321 away from the inlet 301.

[0068] Understandably, the inner side of the housing 32 also has a top surface. In the intended installation state, the top surface is above the bottom surface 321. The top surface and bottom surface 321 can be the boundaries forming the channel 31. Understandably, along the second reference direction F2, the bottom surface 321 is downstream of the top surface.

[0069] In some implementations, combined Figure 8 and Figure 9 As shown, the outer casing 32 includes several casing walls 324, which enclose a certain internal space. This internal space forms a channel 31 under the definition of the partition 33. Specifically, the casing walls 324 include several pairs of opposing casing walls 324. In a predetermined installation state, one pair of casing walls 324 are spaced apart along a second reference direction F2. This pair of casing walls 324 can be used to form the upper and lower boundaries of the channel 31. The lower casing wall 324 is also provided with an oil outlet 323. Another pair of casing walls 324 are spaced apart along both horizontal directions. This pair of casing walls 324 is used to form the boundary of the bent section 311. Optionally, the first edge 331 of the partition 33 is opposite to and spaced apart from this casing wall 324. There is also a pair of casing walls 324 spaced apart along a horizontal front-back direction. One of these casing walls 324 has an inlet 301, and the other has an outlet 302.

[0070] In some other embodiments, the smoke collection box 30 may also have an internal tube that defines a channel 31.

[0071] The above embodiments are merely descriptions of preferred embodiments of this application and are not intended to limit the scope of this application. Any modifications and improvements made by those skilled in the art to the technical solutions of this application without departing from the spirit of this application should fall within the protection scope defined by the claims of this application.
