[0002] Landscape smoke machines typically consist of an atomizer and a lighting assembly. The machine contains a visual smoke chamber where the smoke produced by the atomizer enters for the user's visual enjoyment. The lighting assembly is positioned above the smoke chamber, with its emitting surface facing downwards, projecting light onto the flowing smoke to enhance its dynamic visual effect. The lighting assembly structure includes a light panel and LEDs mounted on it. To ensure the light emitted by the LEDs illuminates evenly from top to bottom within the smoke chamber, the LEDs need to be positioned in the center of the top of the smoke chamber, with their emitting surfaces facing downwards. This layout not only significantly increases the radial dimensions of the smoke machine, affecting its structural compactness, but also results in uneven brightness of the light illuminating the smoke. Utility Model Content

[0003] The main technical problem this application addresses is the uneven brightness of light illuminating the smoke chamber of the smoke machine, and the large radial dimension of the landscape smoke machine.

[0011] More preferably, the reflective structure has an arc-shaped surface, with the concave portion of the arc-shaped surface facing the smoke chamber.

[0012] More preferably, the protrusion includes a guide portion and a cover, the cover is disposed on the top of the guide portion and the top of the guide portion is spaced apart from the cover; the gap between the cover and the guide portion forms a guide channel, the guide channel is connected to the smoke chamber and the mist outlet channel of the atomizer respectively; the LED is disposed on the cover.

[0018] The beneficial effects of this application are:

[0019] By integrating a reflective structure at the top of the smoke chamber, the light emitted by the LEDs is reflected by this structure before entering the smoke chamber. When the smoke machine is operating, the reflected light illuminates the flowing smoke medium, creating a unique visual effect. This reflective structure effectively expands the effective light emission angle, resulting in a more uniform light distribution within the smoke chamber, thus solving the problem of uneven brightness inside the chamber caused by direct downward illumination from the LEDs in existing technologies. Furthermore, by controlling the light propagation path through the reflective structure, the LEDs can be positioned to the side of the smoke chamber (e.g., the top side) instead of directly facing downwards. This design significantly improves the flexibility of LED installation positions, adapting to more installation scenarios, while also helping to reduce the radial installation space required for the LEDs in the smoke machine, thereby reducing the radial dimensions of the equipment.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

Furthermore, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0042] This application provides a smoke generator for converting liquid into smoke, which is then diffused to the outside through smoke flow. Smoke generators are commonly used in aroma diffusers, electronic cigarettes, humidifiers, and other fields. Taking an aroma diffuser as an example, the smoke generated by the smoke generator first enters the smoke chamber 7 for the user to view before being diffused to the outside.

[0043] This application provides a smoke generator, referenced... Figures 1 to 7 The device includes a base 1 and a housing 2, with the housing 2 connected to the base 1, forming a smoke chamber 7. An electronic control component 4 is mounted on the base 1 to control the operation of other electronic components. The electronic control component 4 is located on the side of the base 1 away from the smoke chamber 7 to prevent smoke from affecting the normal operation of the electronic components. The housing 2 includes a top wall 21 and an outer wall 22. One end of the outer wall 22 is connected to the circumferential outer edge of the top wall 21, forming a cover. The other end of the outer wall 22 is connected to the base 1. The housing 2 covers the base 1, forming the smoke chamber 7 between them. The housing 2 has a transparent area corresponding to the smoke chamber 7; that is, a portion of the housing 2 corresponding to the smoke chamber 7 is made of transparent material to allow the user to observe the smoke inside the smoke chamber 7. It should be noted that the transparent area refers to a fully transparent or semi-transparent area. The smoke generator also includes an atomizer 5 and an LED 6. The atomizer 5's mist outlet channel 51 communicates with the smoke chamber 7; the smoke generated by the atomizer 5 flows into the smoke chamber 7, allowing the user to observe the smoke flow. The inner side of the top wall 21 faces the bottom of the smoke chamber 7, and a reflective structure 3 is integrated on the top wall 21, with the reflective surface of the reflective structure 3 facing the smoke chamber 7. An LED 6, electrically connected to the electronic control component 4, is located at the top of the smoke chamber 7, with its emitting surface facing the reflective structure 3. This allows the light emitted by the LED 6 to first strike the reflective structure 3, and after reflection, illuminate the smoke chamber 7, achieving the visual effect of light shining downwards onto flowing smoke, mimicking a natural landscape. The electronic control component 4 includes a main control circuit board 42, or other electronic components capable of controlling the operating state of the LED 6.

[0044] By integrating a reflective structure 3 at the top of the smoke chamber 7, the light emitted by the LED beads 6 is reflected by this structure before entering the smoke chamber 7. When the smoke machine is operating, the reflected light illuminates the flowing smoke medium, creating a unique visual effect. This reflective structure 3 effectively expands the effective light emission angle, making the light distribution within the smoke chamber 7 more uniform, thus solving the problem of uneven brightness inside the chamber caused by the direct downward illumination of the LED beads 6 in existing technologies. On the other hand, by controlling the light propagation path through the reflective structure 3, the LED beads 6 can be arranged to the side of the smoke chamber 7 (e.g., the top side) instead of having to face directly downwards. This design significantly improves the flexibility of the LED bead 6 installation position, adapting to more installation scenarios. It overcomes the limitations of existing designs where the LED bead 6 has a fixed position and the light emission direction can only be downwards, while also helping to reduce the installation space 14 required for the LED beads 6 in the radial direction of the smoke machine (eliminating the need to place them in the central radial area of ​​the smoke chamber 7), thereby reducing the radial size of the equipment.

[0045] In one implementation, such as Figures 2 to 5 As shown, the smoke generator is frustum-shaped and includes a base 1 and a housing 2. The base 1 includes an upper housing 12 and a lower housing 13, which are connected to form an installation space 14. The electronic control assembly 4 is disposed within the installation space 14. The housing 2 includes a top wall 21 and an outer side wall 22. The top wall 21 is, for example, circular. One end of the outer side wall 22 is connected to the outer periphery of the top wall 21, and the other end is connected to the lower housing 13 of the base 1. The upper housing 12 of the base 1 and the housing 2 together form a smoke chamber 7. Specifically, the base 1 has a protrusion 11 on the side facing the smoke chamber 7. The protrusion 11 extends towards the top wall 21 and has a funnel-shaped structure that is smaller at the top and larger at the bottom. The housing 2 covers the outer periphery of the protrusion 11 and is connected to the bottommost end of the protrusion 11. In this embodiment, the protrusion 11 is the upper shell 12 of the base 1, protruding from the lower shell 13 towards the top wall 21. The upper shell 12 has a funnel-shaped structure that is smaller at the top and larger at the bottom, and the outer shell 2 is connected to the lower shell 13. The area of ​​the outer shell 2 corresponding to the protrusion 11 is a transparent area. The outer shell 2 and the protrusion 11 enclose a visible smoke chamber 7, which surrounds the outer periphery of the protrusion 11. The user can observe the smoke inside the smoke chamber 7 through the transparent area. In other embodiments, the protrusion 11 may also be cylindrical or other columnar structures, and the formed smoke chamber 7 may be an annular structure surrounding the protrusion 11.

[0046] Furthermore, the transparent area is, for example, the top wall 21 or the outer wall 22 of the outer casing 2, and is made of a transparent material; preferably, the outer wall 22 is made of a transparent material, so that the user can easily observe the smoke flow through the outer wall 22, and the user has a better viewing angle when viewing the smoke chamber 7 from the outer wall 22. The inner side of the top wall 21 faces the bottom of the smoke chamber 7, and the top wall 21 integrates a reflective structure 3. The reflective surface of the reflective structure 3 faces the smoke chamber 7, so that the light emitted by the LED 6 hits the reflective structure 3, and after reflection, shines from the top of the smoke chamber 7 to the bottom of the smoke chamber 7. The reflective structure 3 is a metal plating, and the metal is, for example, silver or aluminum, a metal that can reflect visible light. The reflective surface facing the smoke chamber 7 means that when the metal coating is set on the top wall 21 located on the inner wall of the smoke chamber 7, the reflective surface of the metal coating is the surface of the metal coating. Since the inner side of the top wall 21 faces the bottom of the smoke chamber 7, the reflective surface naturally also faces the smoke chamber 7. When the metal coating is set on the outer side of the top wall 21 away from the smoke chamber 7, the top wall 21 needs to be made of a light-transmitting material, such as glass or transparent plastic. When the metal coating is set on the outer wall 22, the reflective surface needs to face the inside of the smoke chamber 7 so that the light passes through the light-transmitting material, is reflected on the reflective surface, and finally enters the smoke chamber 7. The LED 6 is located at the top of the protrusion 11, for example, on the top surface 115 of the protrusion 11 or on the circumferential side surface 116 of the protrusion 11 near the top surface 115. The LED 6's location on the protrusion 11 facilitates electrical connection between the LED 6 and the electronic control component 4 on the base 1. Simultaneously, when the housing 2 is detachably connected to the base 1, it protects the integrity of the circuit connecting the LED 6 and the electronic control component 4. The LED 6's location at the top of the protrusion 11 brings it closer to the reflector structure 3, allowing more light emitted by the LED 6 to reach the reflector structure 3, resulting in better light distribution.

[0047] In one implementation, such as Figure 3 As shown, the reflective structure 3 has an arc-shaped surface 31, with the concave portion of the arc-shaped surface 31 facing the smoke cavity 7. Specifically, the top wall 21 has an arc-shaped portion, and when the reflective structure 3 is a thin layer disposed on the top wall 21, the resulting reflective structure 3 has an arc-shaped surface 31. The arc-shaped surface 31 has a concave portion, which faces the smoke cavity 7. The arc-shaped portion allows the reflected light to converge directionally, reducing stray light loss and increasing the brightness of the light illuminating the smoke.

[0048] In one implementation, such as Figures 2 to 4As shown, the protrusion 11 includes a horizontal top surface 115 and a circumferential side surface 116 surrounding the periphery of the horizontal top surface 115. The LED 6 is disposed on the circumferential side surface 116 of the protrusion 11, and is located on the side of the circumferential side wall closer to the horizontal top surface 115. Specifically, the protrusion 11 includes a guide portion 112 and a cover 111, with the cover 111 positioned above the guide portion 112. The guide portion 112 is funnel-shaped, wider at the bottom than the top, allowing smoke to flow downwards along the side wall of the guide portion 112, the shape of which forms the path of the smoke flow. The cover 111 is larger than the top of the guide section 112, completely covering the top of the guide section 112. The cover 111 and the top of the guide section 112 are spaced apart. The cover 111 and the guide section 112 are fixed together by a connecting post 114. The gap between them forms a guide channel 113, which connects the mist outlet channel 51 of the atomizer 5 to the smoke chamber 7. This allows the smoke generated by the atomizer 5 to pass sequentially through the mist outlet channel 51, the guide channel 113, and then to the smoke chamber 7. By placing the cover 111 on the guide section 112 and mounting the LED 6 on the cover 111, the guide channel 113 can be positioned below the LED 6. The smoke flows into the smoke chamber 7 after passing through the guide channel 113, and the light is not affected by the smoke. If the LED 6 is positioned at the bottom of the guide channel 113, the smoke will block the light, making it difficult for the light to penetrate the smoke and illuminate the reflective structure 3, thus reducing the brightness of the smoke chamber 7. Specifically, the cover 111 includes the aforementioned upper surface and peripheral sidewall 1161. The upper surface is the aforementioned top surface 115, and the peripheral sidewall 1161 is a part of the aforementioned circumferential side surface 116. The peripheral sidewall 1161 of the cover 111 and the sidewall of the guide portion 112 together form the circumferential side surface 116 of the protrusion 11, and the lamp bead 6 is disposed on the peripheral sidewall 1161.

[0049] Furthermore, such as Figure 2 , Figure 3 As shown, the electronic control component 4 includes a main control circuit board 42 and a first circuit board 41. The main control circuit board 42 is located in the mounting space 14 within the base 1, and the first circuit board 41 is located on the cover 111. The main control circuit board 42 and the first circuit board 41 are electrically connected. The LED beads 6 are located on the first circuit board 41. By placing the first circuit board 41 on the cover 111, it is convenient to connect the wiring of the LED beads 6. In one embodiment, a wiring channel is provided in the connecting post 114. The wires connecting the main control circuit board 42 and the first circuit board 41 pass through the wiring channel to achieve electrical connection between the two. Placing the wires in the wiring channel prevents smoke from entering the mounting space 14.

[0050] In one implementation, such as Figure 5 , Figure 6As shown, the outer casing 2 includes a top wall 21 and an outer wall 22. The top wall 21 is circular, and the outer wall 22 is a circular tube. The reflective structure 3 is integrated on the top wall 21 and is either circular or ring-shaped. A first circuit board 41 is disposed on the cover 111, and multiple LED beads 6 are provided on the first circuit board 41. The multiple LED beads 6 are spaced apart along the circumference of the cover 111, for example, multiple LED beads 6 are arranged around the circumference of the side wall 1161, so that the light illuminating the reflective structure 3 is uniform, and the brightness of the light reflected into the smoke chamber 7 is also more uniform. In other embodiments, there may be one or two LED beads 6, and the number of LED beads 6 is not limited.

[0051] In one implementation, such as Figure 2 , Figure 3 As shown, the smoke generator has a height direction consistent with the vertical direction, and the radial direction of the smoke generator is perpendicular to the height direction. LED beads 6 are disposed on the peripheral sidewall 1161 of the cover 111, and the main emitting surface of the LED beads 6 faces the direction perpendicular to the height of the smoke generator; understandably, the main emitting surface of the LED beads 6 faces the radial direction of the smoke generator. The reflective structure 3 slopes downwards from the end near the LED beads 6 away from them, and the orthographic projection of the LED beads 6 along the vertical direction of the smoke generator falls completely onto the reflective structure 3. Specifically, the reflective structure 3 has a top and a bottom, with the top located above the bottom in the height direction of the smoke generator. The reflective structure 3 slopes downwards from the end near the LED beads 6 away from them, and the orthographic projection of the LED beads 6 along the radial direction of the smoke generator falls completely into the area between the top and the bottom. It should be noted that the main luminous surface refers to the surface corresponding to the peak of the luminous intensity distribution. For example, if the luminous surface of LED 6 is a plane, the main luminous surface is the entire plane. If the luminous surface of LED 6 is hemispherical, the orientation of the main luminous surface is the orientation of the top of the spherical surface. The reflective structure 3 has a top and a bottom. The top is located above the bottom in the height direction of the smoke machine. The reflective structure 3 is inclined downward from the end near LED 6 away from LED 6, and the orthographic projection of LED 6 along the radial direction of the smoke machine is located above the bottom. This ensures that the main light emitted from the main luminous surface can be projected onto the reflective structure 3 and then reflected into the smoke cavity 7. This ensures that as much of the brighter light as possible is reflected before illuminating the smoke cavity 7, improving the uniformity of the light brightness in the smoke cavity 7.

[0052] In one implementation, reference Figures 1 to 6The top wall 21 of the outer casing 2 has a connecting hole 23 in the middle area, and a reflective structure 3 surrounds the connecting hole 23 outwards. The top of the protrusion 11 has a first electrical connection part 81, and the atomizer 5 has a second electrical connection part 82 that mates with the first electrical connection part 81. The atomizer 5 is located outside the outer casing 2, and the second electrical connection part 82 is connected to the first electrical connection part 81 through the connecting hole 23. Specifically, the top includes the aforementioned cover 111 and guide part 112. The first electrical connection part 81 is, for example, a spring pin, and is disposed on the aforementioned first circuit board 41, protruding from the top surface 115 of the cover 111. The middle area of ​​the top wall 21 has a connecting hole 23, which is fitted onto the protrusion 11, causing the first electrical connection part 81 to protrude outwards from the connecting hole 23. The atomizer 5 is provided with a second electrical connection part 82, which may be, for example, a metal sheet. The atomizer 5 is located on the outside of the outer casing 2, and the circuit is connected through the first electrical connection part 81 and the second electrical connection part. The cover 111 also serves to support the outer casing 2. Through the connection hole 23 and the location of the first electrical connection structure, the atomizer 5 can be replaced outside the vaporizer, which is convenient for user operation. The LED 6 and the first electrical connection part 81 are both located on the first circuit board 41, which simplifies the circuit connection inside the vaporizer.

[0053] In one implementation, such as Figures 2 to 5 As shown, the protrusion 11 is disposed within the connecting hole 23. The protrusion includes a top surface 115 and a circumferential side surface 116. The circumferential side surface 116 of the protrusion 11 is tightly fitted with the connecting hole 23. The first electrical connection part 81 is disposed on the top surface 115. Specifically, the cover 111 includes a top surface 115 and a circumferential side surface. The connecting hole 23 has the same shape and size as the top surface 115. When the outer shell 2 is connected to the cover 111, the top surface 115 of the cover 111 is located within the connecting hole 23, and the circumferential side surface is tightly fitted with the connecting hole 23 to prevent smoke from escaping from the connecting hole 23 and affecting the flow path of smoke in the visualization cavity.

[0054] In one implementation, such as Figure 2 , Figure 3 As shown, the fogging machine also includes a sealing element 9, which is annular in shape. The inner side of the sealing element 9 is fitted around the outer periphery of the cover 111 and tightly fits against the peripheral sidewall 1161 of the cover 111. The inner side of the sealing element 9 is located between the LED 6 and the flow channel 113. The outer side of the sealing element 9 is connected to the outer shell 2 and fits tightly, thus separating the LED 6 from the fog chamber 7 and preventing the fog flowing out from the flow channel 113 from affecting the normal operation of the LED 6 and the first circuit board 41. Furthermore, the outer side of the sealing element 9 is connected below the reflective structure 3. The sealing element 9 is made of a light-transmitting material to ensure that the reflected light can pass through the sealing element 9 and illuminate the atomizing chamber.

[0055] In one implementation, reference Figures 1 to 6 The outer casing 2 is also provided with a fragrance vent 24, which communicates with the smoke chamber 7 and is located on the side of the sealing member 9 away from the lamp bead 6. Specifically, the fragrance vent 24 is located on the top wall 21 and on the side of the sealing member 9 away from the lamp bead 6. For example, the outer side of the annular sealing member 9 is connected to the top wall 21, and the fragrance vent 24 is located on the outermost side of the top wall 21, close to the outer wall 22. Multiple fragrance vents 24 are provided and evenly arranged along the circumference of the top wall 21, so that the smoke can be emitted from the smoke chamber 7. If the fragrance vent 24 is located on the side of the sealing member 9 close to the lamp bead 6, the smoke cannot be emitted from the fragrance vent 24.

[0056] In one implementation, such as Figure 2 , Figure 7 As shown, the fog machine also includes a fan, and the fog machine has a first connecting channel and a second connecting channel. A first guide channel 113 is provided on the cover 111, which runs through the cover 111 along the height of the fog machine. The first guide channel 113 connects to the fog outlet channel 51 of the atomizer 5. The smoke generated by the cartridge passes sequentially through the fog outlet channel 51, the first connecting channel, and the guide channel 113, finally entering the smoke chamber 7. The fan is located within the installation space 14. The second connecting channel passes through the center of the connecting column 114 and the guide cover, and connects to the air inlet channel 52 of the atomizer 5 and the air outlet of the fan. The air blown by the fan enters the air inlet channel 52, carrying the smoke generated by the atomizer 5 out through the fog outlet channel 51. When the atomizer 5 is connected to the cover 111, the second connecting channel connects to the air inlet channel 52 of the atomizer 5, and the first connecting channel connects to the fog outlet channel 51 of the atomizer 5, achieving smoke flow.
