Description

Technical Field

[0001] This application relates to the field of atomization technology, and more particularly to a fogging machine. Background Technology

[0002] Landscape smoke machines, designed to achieve visually appealing dynamic smoke effects, typically consist of an atomizer and a visual smoke chamber. The smoke generated by the atomizer is injected into the smoke chamber via a delivery pipe, following a complex flow path of "first radial uniform diffusion, then axial settling" to ensure the smoke fills the chamber and creates the visual effect of smoke flowing from the top to the bottom. To achieve this flow path, a cone-shaped guide is usually placed inside the smoke chamber, with a cap on top. The cap covers the top of the guide and forms an outlet facing the bottom of the smoke chamber, spaced apart from the side wall of the guide. The outlet end of the delivery pipe connects to the diffusion chamber between the guide and the cap, allowing the smoke generated by the atomizer to first enter the diffusion chamber, diffuse radially uniformly within it, and then flow downwards along the side wall of the guide from the outlet. This design is highly dependent on the cap and requires precise assembly clearance between the cap and the guide, increasing the difficulty of precision manufacturing, structural complexity, and assembly.

[0037] This application provides a smoke generator, which incorporates an atomizer 2 to convert liquid into a smoke-like substance, making the liquid easier to diffuse and providing visual appeal to the user. Smoke generators are commonly used in areas such as smoke-based aromatherapy and humidifiers.

[0038] This application provides a smoke generator, referenced... Figures 1 to 6The device includes a housing 1, an atomizer 2, a fan 61, and a separator 3. The separator 3 is located inside the housing 1. A first side 31 of the separator 3 forms a smoke chamber 13 with the housing 1. The separator 3 has a second side 32 opposite to the first side 31, which forms a mounting cavity 14 with the housing 1. The separator 3 divides the cavity inside the housing 1 into the smoke chamber 13 and the mounting cavity 14. The smoke chamber 13 is used to contain smoke, and the mounting cavity 14 is used to mount electronic devices, such as the fan 61, a battery, and a circuit board 63. At least a portion of the housing 1 corresponding to the smoke chamber 13 is made of transparent material, allowing the user to observe the smoke flow inside the smoke chamber 13 through the transparent housing. The fan 61 is located inside the mounting cavity 14, separated from the smoke chamber 13, to prevent smoke from affecting the normal operation of the fan 61. The atomizer 2 has an air inlet 21 and a mist outlet 22 that are interconnected. The air inlet 21 is connected to the air outlet of the fan 61, and the mist outlet 22 is connected to the smoke chamber 13. Smoke is generated inside the atomizer 2. The air blown out by the fan 61 enters through the air inlet 21 and then drives the smoke to flow out through the mist outlet 22, thus completing the mist outlet function of the atomizer 2 and allowing the smoke to enter the smoke chamber 13. The outer shell 1 includes a top wall 111 and a base 12 arranged opposite to each other, and a side wall 112 surrounding the outer periphery of the top wall 111 and the base 12. The separator 3 includes a top plate 33 and a side plate 34 surrounding the outer periphery of the top plate 33; the top wall 111 and the top plate 33 form a diffusion channel 131 of the smoke chamber 13 at intervals, and the side plate 34 and at least part of the side wall 112 form a sinking channel 132 of the smoke chamber 13 at intervals, and the diffusion channel 131 is connected to the sinking channel 132; a mist outlet channel 15 is connected to the area on the diffusion channel 131 away from the connection between the diffusion channel 131 and the sinking channel 132, and the mist outlet channel 15 is connected to the mist outlet part 22 of the atomizer 2 and the diffusion channel 131 respectively; so that the smoke generated by the atomizer 2 flows out from the mist outlet part 22 of the atomizer 2, enters the mist outlet channel 15 and the diffusion channel 131 in sequence, and then enters the sinking channel 132.

[0039] This application utilizes a partition 3 to form a diffusion channel 131, with a top plate 33 and a top wall 111 of the outer shell 1. A side plate 34 of the partition 3 and a side wall 112 of the outer shell 1 form a sinking channel 132. The diffusion channel 131 and the sinking channel 132 are connected. A mist outlet channel 15 is connected to the area of ​​the diffusion channel 131 away from the connection point between the diffusion channel 131 and the sinking channel 132. This allows the smoke generated by the atomizer 2 to flow out from the mist outlet 22 and enter the smoke chamber 13. After diffusing outwards through the diffusion channel 131, the smoke then flows downwards into the sinking channel 132, achieving a uniform downward flow of smoke. Through the cooperation of the partition 3 and the outer shell 1, compared to existing technologies, the smoke achieves the same flow path, eliminating the need for a cap, reducing structural complexity, simplifying assembly, and improving production efficiency.

[0040] In one implementation, such as Figures 1 to 3 As shown, the outer casing 1 of the smoke generator is similar to a columnar body. Along the height of the smoke generator, there is a top wall 111 and a base 12. Side walls 112 surround the outer periphery of the top wall 111 and the base 12, forming a receiving cavity. A partition 3 is provided within the receiving cavity. The partition 3 includes a top plate 33 at the top and side plates 34 surrounding the outer periphery of the top plate 33. In one embodiment, to achieve uniform diffusion of smoke within the smoke chamber 13 in the diffusion channel 131 before entering the sinking channel 132 relative to the diffusion channel 131, the top plate 33 and the side plate 34 are connected at an angle greater than 45° and less than 150°, forming a distinct bending connection. The side plate 34 is connected to the base 12, presenting a structure where the partition 3 protrudes from the base 12, so that the partition 3 and the base 12 form a mounting cavity 14 for installing electronic devices. Specifically, the top plate 33 and the side plate 34 face the base 12 together, forming the second side 32 of the separator 3. The second side 32 and the base 12 form the mounting cavity 14. Understandably, the separator 3 has a first side 31 opposite to the second side 32. The surfaces of the top plate 33 and the side plate 34 opposite to the second side 32 form the first side 31. The first side 31, the top wall 111, and the side wall 112 form the smoke chamber 13. The smoke chamber 13 and the mounting cavity 14 are arranged vertically in the height direction of the vaporizer, with the smoke chamber 13 located above the mounting cavity 14. The smoke generated by the atomizer 2 enters the smoke chamber 13, while the electronic components are housed in the mounting cavity 14. The separator 3 separates the two cavities, preventing the smoke from forming liquid and entering the mounting cavity 14, which could cause a short circuit in the electronic components. In this embodiment, the outer shell 1 corresponding to the smoke chamber 13 is at least partially made of a transparent material. For example, both the top wall 111 and the side walls 112 are made of transparent material, allowing the user to observe the flow pattern of the smoke inside the smoke chamber 13. In other embodiments, only the top wall 111 or only the side walls 112 may be made of transparent material. It should be noted that the transparent material here includes fully transparent and semi-transparent materials, as long as the smoke inside the smoke chamber 13 can be observed.

[0041] Furthermore, the top wall 111 and the top plate 33 are spaced apart to form a diffusion channel 131 of the smoke chamber 13, and the side plate 34 and at least part of the side wall 112 are spaced apart to form a sinking channel 132 of the smoke chamber 13. The top wall 111 and the side wall 112 are also connected at an angle greater than 45° and less than 150°. The shape formed by the top wall 111 and the side wall 112 is the same as the shape formed by the top plate 33 and the side plate 34. The top wall 111 and the top plate 33 are spaced apart to form the diffusion channel 131, and the side wall 112 and the side plate 34 are spaced apart to form the sinking channel 132. The air inlet 21 of the atomizer 2 is the inlet for the air blown by the fan 61 to enter the atomizer 2, and the mist outlet 22 of the atomizer 2 is the outlet for the smoke inside the atomizer 2 to flow out. The atomizer 2 has a channel connecting the air inlet 21 and the mist outlet 22, and the smoke generating device is disposed in the channel. The mist outlet 22 is connected to the mist outlet channel 15, which is located at the junction of the diffusion channel 131 and the sinking channel 132. This allows the smoke generated by the atomizer 2 to flow out of the mist outlet 22 and sequentially pass through the mist outlet channel 15, the diffusion channel 131, and the sinking channel 132. The smoke first diffuses evenly in the diffusion channel 131, and then flows from the junction of the diffusion channel 131 and the sinking channel 132 towards the bottom of the sinking channel 132. Since the diffusion channel 131 is formed by the spaced top wall 111 and top plate 33, and the sinking channel 132 is formed by the spaced side wall 112 and side plate 34, both the diffusion channel 131 and the sinking channel 132 are elongated channels, resulting in a more orderly smoke flow and a better overall effect.

[0042] It should be noted that in this application, the height direction of the smoke machine is the same as the direction of gravity and the vertical direction; the radial direction of the smoke machine is perpendicular to the height direction of the smoke machine, also known as the horizontal direction; this will not be elaborated further below.

[0043] In one implementation, such as Figure 1 , Figure 2As shown, the diffusion channel 131 has a top end connected to the mist outlet channel 15, and the diffusion channel 131 extends downward at an angle away from the central axis of the smoke generator. Specifically, the mist outlet channel 15 is located at the center of the top wall 111 or the top plate 33, and the connection between the mist outlet channel 15 and the diffusion channel 131 is the top end of the diffusion channel 131. The diffusion channel 131 extends downward at an angle away from the central axis of the smoke generator, forming a cone-shaped mist channel. This allows the smoke to flow out of the mist outlet channel 15, impact the wall opposite the mist outlet channel 15, and diffuse outward at an angle. Because the smoke has weight, the downwardly angled diffusion channel 131 allows the smoke to flow more smoothly and prevents liquid accumulation within the diffusion channel 131. Specifically, the top wall 111 and the top plate 33 also extend downward at an angle away from the central axis of the smoke generator, forming a cone shape, corresponding to the shape of the diffusion channel 131. In other embodiments, the top wall 111 and the top plate 33 may also be circular, forming a circular diffusion channel 131; the mist outlet channel 15 is connected to the central area of ​​either the top wall 111 or the top plate 33, and the smoke flows out from the mist outlet channel 15, impacts the wall opposite the mist outlet channel 15, diffuses evenly in all directions, and flows towards the sinking channel 132.

[0044] In one implementation, such as Figure 1 , Figure 2 As shown, the sinking channel 132 extends vertically, and the angle formed by the diffusion channel 131 and the sinking channel 132 on the side facing the separator 3 is greater than 90° and less than 150°. Specifically, the diffusion channel 131 extends downwards at an angle from the top away from the central axis of the smoke generator, as described above. The bottom end of the diffusion channel 131 connects to the sinking channel 132, and the angle formed by their connection is greater than 90° and less than 150°. By setting the sinking channel 132 to extend vertically, the corresponding sidewall 112 and side plate 34 of the sinking channel 132 also extend vertically, which not only facilitates production and processing, but also creates a waterfall-like, straight-down visual effect by the smoke flowing vertically downwards from the top of the sinking channel 132, thus improving the visual experience.

[0045] In one implementation, such as Figure 1 , Figure 2 and Figure 5As shown, a recess 16 is provided in the middle of one of the top plate 33 and the top wall 111, and a mist outlet channel 15 is provided in the other. The outlet of the mist outlet channel 15 is directly opposite the recess 16, so that after the smoke flows out of the mist outlet channel 15, it hits the recess 16 and then flows evenly to the surrounding area, making the smoke flow more evenly in the diffusion channel 131 and improving the visual effect. Specifically, when the atomizer 2 is placed in the mounting cavity 14, the mist outlet channel 15 is placed in the middle area of ​​the top plate 33 and penetrates the top plate 33 vertically. One end of the mist outlet channel 15 is connected to the mist outlet part 22 of the atomizer 2, and the other end is connected to the diffusion channel 131, and the outlet of the mist outlet channel 15 is directly opposite the recess 16 on the inner side of the top wall 111. When the atomizer 2 is located outside the outer casing 1, the mist outlet channel 15 is located in the middle area of ​​the top wall 111 and penetrates the top wall 111. The mist outlet portion 22 of the atomizer 2 is connected to the end of the mist outlet channel 15 near the atomizer 2. The mist outlet channel 15 is connected to the diffusion channel 131, and the outlet of the mist outlet channel 15 is directly opposite the recess 16 on the top plate 33. Specifically, in one embodiment, the top wall 111 includes an outer wall and a support member 4. The support member 4 is spaced apart from and fixedly connected to the top plate 33. The outer wall is connected to the support member 4, and the support member 4 serves to support and fix the outer wall 112 and to support the atomizer 2. When the atomizer 2 is installed outside the outer shell 1, a through hole 1111 is provided on the outer wall, and the atomizer 2 is connected to the support 4 through the through hole 1111; the mist outlet channel 15 is located in the middle area of ​​the support 4 and penetrates the support 4 in the vertical direction. The mist outlet part 22 of the atomizer 2 is connected to one end of the mist outlet channel 15 near the atomizer 2, and the other end of the mist outlet channel 15 is connected to the diffusion channel 131. The outlet of the mist outlet channel 15 is directly opposite the recess 16 on the top plate 33.

[0046] In one implementation, such as Figures 1 to 5 As shown, the outer casing 1 also includes a base 12 disposed opposite to the top wall 111. The side wall 112 and the top wall 111 are integrally formed and are collectively referred to as the outer cover 11. The bottom of the side wall 112 is detachably connected to the base 12. When smoke liquefies in the smoke chamber 13 to form water droplets, the water droplets remain in the smoke chamber 13. The water droplets in the smoke chamber 13 can be wiped away by opening the outer cover 11. The separator 3 also includes an annular bottom plate 35. The bottom plate 35 is connected to the base 12. The inner side of the bottom plate 35 is connected to the bottom of the side plate 34, and the outer side of the bottom plate 35 extends towards the side wall 112, so that the bottom plate 35 protrudes outward from the side plate 34. The bottom plate 35 is fully exposed, which facilitates the connection between the bottom plate 35 and the base 12. Furthermore, the connection between the bottom plate 35 and the base 12 will not damage the mounting cavity 14 when the outer cover 11 is disassembled, thus increasing the sealing of the mounting cavity 14.

[0047] Furthermore, the base plate 35 extends horizontally to form an installation plane, and the base 12 also has a horizontal connecting surface 121. The connecting surface 121 fits snugly against the base plate 35, which not only simplifies installation but also ensures a tighter fit between the base plate 35 and the base 12, making it more difficult for liquid to enter the installation cavity 14. In one embodiment, an annular seal 62 is provided between the base plate 35 and the base 12. The annular seal 62 is positioned between the connecting surface 121 of the base plate 35 and the base 12. Specifically, the connecting surface 121 has an annular groove on the side facing the base plate 35, and the seal 62 is positioned within and protrudes from the annular groove, allowing the seal 62 to be press-fitted with the base plate 35. The seal 62 can be made of elastic materials such as silicone or sponge.

[0048] In one implementation, such as Figure 1 , Figure 2 As shown, a baffle 18 is provided on the side of the top wall 111 near the smoke chamber 13 and corresponding to the connection between the top plate 33 and the side plate 34. The baffle 18 protrudes from the surface of the top wall 111, and the top of the baffle 18 faces the sinking channel 132. The top of the baffle 18 is the position where the distance between the baffle 18 and the surface of the top wall 111 is the greatest. The baffle 18 is located at the connection between the top plate 33 and the side plate 34. Specifically, the baffle 18 is located at the end of the diffusion channel 131 and the top of the sinking channel 132; and the protruding top of the baffle 18 faces the sinking channel 132. The baffle 18 forms a downwardly inclined guide section from the side near the central axis of the smoke machine to the top of the baffle 18; driving the smoke to flow downward to the sinking channel 132. Meanwhile, the structure of the baffle 18 causes the end of the diffusion channel 131 to contract. When the smoke reaches the end of the diffusion channel 131, the air pressure at the end increases due to the tightening of the end of the diffusion channel 131. Furthermore, the top of the baffle 18 is closer to the side wall 112 in the horizontal direction than the side plate 34 of the separator 3. Combined with the effect of the guide section, when the smoke enters the sinking channel 132 from the diffusion channel 131, it flows downwards along the outer surface of the side plate 34, preventing the smoke from accumulating at the top of the sinking channel 132 and dissipating into the outside. This improves the visual appeal of the smoke.

[0049] In one implementation, such as Figure 1 , Figure 3 As shown, the outer casing 1 is provided with a fragrance vent 17, which is connected to the smoke chamber 13, allowing smoke to escape to the outside through the fragrance vent 17. The fragrance vent 17 is located on the side of the aforementioned baffle 18 away from the center of the top wall 111. The baffle 18 can block the smoke, reducing the risk that the smoke will escape to the outside before flowing to the bottom of the sinking channel 132, thereby improving the smoke viewing effect.

[0050] In one embodiment, a guide section 19 is provided on the side of the side plate 34 near the side wall 112. An air outlet channel 191 is provided in the guide section 19. The air outlet channel 191 connects the smoke chamber 13 and the air outlet of the fan 61. When the smoke flows to the bottom of the sinking channel 132, the fan 61 is started. The air blown out by the fan 61 enters the smoke chamber 13 through the air outlet channel 191, and then blows the smoke gathered at the bottom of the sinking channel 132 toward the fragrance dispersing port 17. Specifically, the outlet of the air outlet 191 is configured to allow the air blown by the fan 61 to flow circumferentially along the side plate 34. For example, the side plate is a circular tube, and the outlet of the air outlet 191 faces the tangential direction of the outer side of the side plate 34. For example, the guide portion is an arc-shaped tube protruding from the outer surface of the side plate 34. The air outlet 191 passes through the air guide portion 19, and the outlet of the air outlet 191 is formed on the air guide portion 19. The outlet of the air outlet 191 faces the tangential direction of the side plate 34, that is, the air blown by the fan blows out along the circumferential direction of the side plate 34, making the airflow of the fan into the smoke chamber 13 more orderly and reducing the probability of turbulence in the smoke chamber 13. This not only makes the smoke blown out in an orderly manner and improves the visual appeal, but also improves the fogging efficiency and prevents the risk of water droplets. In one embodiment, the outlet of the air outlet 191 is located above the bottom plate 35 of the partition 3 to prevent liquid from entering the mounting cavity 14 through the outlet of the air outlet 191 and affecting the use of electronic devices.

[0051] In one implementation, such as Figures 1 to 4As shown, the vapor generator also includes a support 4, a conductive post 64, and a circuit board 63. The support 4 is located above the top plate 33, and the support 4 and the top plate 33 are spaced apart and fixedly connected by a connecting post 65, so that a fixed gap space is formed between the top plate 33 and the support 4. In this embodiment, the atomizer 2 is located on the outside of the outer shell 1 for easy replacement of the atomizer 2. Therefore, the vapor generated by the atomizer 2 needs to enter the vapor chamber 13 from top to bottom, and the vapor outlet channel 15 needs to be located on the top wall 111 of the outer shell 1. However, since the atomizer 2 needs to be electrically connected to the circuit board 63 in the mounting cavity 14, if the conductive structure is located on the outer shell 1, it will affect the detachability of the outer cover 11 and make it impossible to wipe the water droplets in the vapor chamber 13, affecting the user experience. Therefore, in order to balance the detachability of the outer cover 11 and the convenient replacement of the atomizer 2, the support 4 needs to be provided, the conductive structure is located on the support 4, and the outer shell 1 is then detachably connected to the support 4, thus achieving the above requirements. Therefore, the support 4 is fixedly mounted on the top plate 33, the mist outlet channel 15 is mounted on the support 4 and passes through the support 4 in the vertical direction, and the atomizer 2 is detachably connected to the support 4; specifically, the mist outlet 22 of the atomizer 2 is connected to the upper part of the mist outlet channel 15, and the lower part of the mist outlet channel 15 (the outlet of the mist outlet channel 15) is directly opposite the recess 16 on the top plate 33, so that the smoke flows downward from the mist outlet channel 15, hits the recess 16 on the top plate 33, and then diffuses evenly in the diffuser. Furthermore, the circuit board 63 is disposed within the mounting cavity 14 to prevent short circuits. The conductive post 64 is disposed on the circuit board 63, passing through the top plate 33 and the support member 4, and protruding from the side of the support member 4 away from the top plate 33. The outer shell 1 is provided with a through hole 1111, which mates with the support member 4 and is detachably connected to it. When the outer shell 1 is connected to the support member 4, the conductive post 64 is located within the through hole 1111. The conductive part of the atomizer 2 is electrically connected to the conductive post 64 through the through hole 1111. The conductive post 64 is a conductive spring pin, and the conductive part of the atomizer 2 is a metal sheet. The conductive spring pin abuts against the metal sheet to energize the atomizer 2 and facilitates easy disassembly of the atomizer 2.

[0052] In one implementation, such as Figure 4 As shown, the support member 4 has a locking part 41 on the side away from the top plate 33. The locking part 41 protrudes from the surface of the support member 4 and is connected to the through hole 1111. For example, when the outer shell 1 is connected to the support member 4, the locking part 41 just passes through the through hole 1111 and fits tightly with the through hole 1111 to prevent the smoke generated by the atomizer 2 from entering the diffusion channel 131 and then dissipating from the through hole 1111 before flowing through the sinking channel 132. Furthermore, the conductive post 64 needs to penetrate the locking part 41 vertically and be exposed on the upper surface of the locking part 41 to realize the electrical connection of the atomizer 2.

[0053] In one implementation, such as Figure 1 , Figure 3 and Figure 4 As shown, the support 4 is provided with a first magnetic element 51, which is located on the upper surface of the support 4. A second magnetic element 52 is provided on the top wall 111 corresponding to the first magnetic element 51. The first magnetic element 51 and the second magnetic element 52 are magnetically attracted to each other, ensuring that the outer cover 11 is not easily shaken. Furthermore, during the process of the outer cover 11 covering the base 12, the magnetic attraction between the first magnetic element 51 and the second magnetic element 52 helps the outer cover 11 to be quickly positioned and installed on the support 4, thereby improving the user experience. In one embodiment, the support 4 is provided with a third magnetic element 53, and the atomizer 2 is provided with a fourth magnetic element 54 corresponding to the third magnetic element 53. The third magnetic element 53 and the fourth magnetic element 54 are attracted to each other to fix the atomizer 2, preventing it from falling off the support 4. This also serves the purpose of quick positioning, improving the user experience.

[0054] In one implementation, such as Figure 2 As shown, an LED bead 66 is installed inside the mounting cavity 14. The LED bead 66 is electrically connected to the circuit board 63, and the light-emitting surface of the LED bead 66 faces the partition 3. The partition 3 is made of a light-transmitting material, and the light generated by the LED bead 66 is projected onto the partition 3, causing the partition 3 to light up. The partition 3 can be a milky white light-transmitting component, which can both shield the electronic components inside the mounting cavity 14 from view when the LED bead 66 is not working, preventing the user from seeing them and affecting the visual experience; and allow the light to pass through the partition 3 when the LED bead 66 is working, so that the user can see the lighting effect. The combination of light and smoke enhances the visual appeal.

[0055] Furthermore, the partition 3 has a tubular light-blocking part 36 on the side near the mounting cavity 14. The light-blocking part 36 extends vertically downward from the top plate 33 and is spaced apart from the side plate 34. The fan 61 is located on the side of the light-blocking part 36 away from the side plate 34. In other words, the fan 61 and other electronic components are enclosed inside the light-blocking part 36 to prevent the shadows cast by the fan 61 and other electronic components from appearing on the partition 3 when the lamp bead 66 is lit, thus affecting the aesthetics.

All equivalent structural transformations made based on the concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
