Description

Technical Field

[0001] This invention relates to the field of special effects equipment, and more particularly to an automatic smoke ring machine. Background Technology

[0002] A smoke ring machine is a special effects device used in stage performances, commercial celebrations, film and television shooting, and other scenes to produce large-sized, long-distance, and highly stable smoke rings, creating a stunning visual effect.

[0003] Existing smoke ring machines, such as the smoke ring forming device and machine described in announcement number CN211836321U, mainly rely on a connecting rod assembly to move the center of an elastic diaphragm from a position near the nozzle to a position away from the nozzle, creating negative pressure within the smoke ring forming chamber. External air is then supplied to the chamber through the nozzle, and under the elastic restoring force of the diaphragm, a pulsed airflow is generated towards the nozzle, expelling the smoke and airflow from the chamber to form a smoke ring. However, with repeated use, the elastic diaphragm in this technology is prone to structural deformation, fatigue damage, and elasticity decay, failing to provide a stable pulsed airflow intensity. This results in loose smoke rings, affecting the visual effect. Furthermore, the spray distance of the smoke ring is adjusted by moving the center of the elastic diaphragm away from the nozzle using the connecting rod assembly. The air intake within the smoke ring forming chamber is limited by the deformation range of the elastic diaphragm, preventing wide-range adjustment based on actual usage needs. This narrow adjustable range makes it unsuitable for various scenarios, such as small events or large stages. Summary of the Invention

[0025] The beneficial effects achieved by this invention are as follows: The automatic smoke ring machine provided by this invention uses a driving component to drive the jet component to generate pulsed airflow, replacing the existing technology that relies on the elastic impact during the deformation of an elastic membrane to generate pulsed airflow. During the operation of the jet component, external air is continuously drawn into the air storage chamber along the jet channel, and this air is converted into pulsed airflow that propels the smoke and airflow in the storage chamber towards the baffle plate. The pulsed airflow pushes the smoke and airflow in the storage chamber out through the nozzle to form a smoke ring, thus achieving automatic smoke ring production. This pulsed airflow generation does not rely on component deformation; the jet component provides a stable pulsed airflow intensity, ensuring a consistently stable smoke ring shape and extending the service life of the automatic smoke ring machine. Furthermore, since the smoke ring's spray distance is mainly determined by the impact force and duration of a single pulsed airflow in the storage chamber, and the operating parameters of the driving component directly affect these factors, the impact force and duration of a single pulsed airflow can be increased by increasing the driving component's rotation speed and lengthening its operating time, thereby increasing the smoke ring's spray distance. The ratio of the drive component's rotation speed to its running time is used to create different start-stop frequencies, thereby adjusting the pulse frequency, duration, and intensity of the pulsed airflow generated by the jet component. This allows for a wide range of adjustment of the smoke ring's spray distance, improving the consistency and controllability of smoke ring formation, and adapting to different usage scenarios such as small events and large stages. In addition, the output end of the smoke generating component is connected to the first passageway on the machine body that connects the equipment cavity and the smoke storage cavity and / or the air storage cavity. The smoke generated by the smoke generating component after being heated in the equipment cavity is directly sent into the smoke storage cavity along its output end, or directly sent into the air storage cavity and then flows into the smoke storage cavity along the jet channel. The smoke oil can be continuously pumped into the smoke generating component according to actual needs under the action of the oil pump component, ensuring that the smoke generating component continuously and stably produces high-concentration smoke. This high-concentration smoke can be better wrapped and pushed by the pulsed airflow generated by the jet component, forming high-concentration, full-shaped, and clearly colored smoke rings with a clearer visual effect. At the same time, after the smoke ring is formed, the high-concentration smoke particles have strong cohesion and are not easily blown away by the external airflow, maintaining their complete shape in the air for a long time, which is conducive to forming long-distance smoke rings.

Detailed Implementation

[0036] like Figures 1-9As shown, as an embodiment of the present invention, an automatic smoke ring machine is provided, including a body 1, a smoke generating component 2, and a jet driving component 3. The body 1 includes a main housing 11 and a casing housing 12 disposed at the rear of the main housing 11, with a device cavity 101 formed inside the casing housing 12. The main housing 11 has a smoke storage cavity 102, an air storage cavity 103 disposed between the smoke storage cavity 102 and the device cavity 101, and a jet passage 104 communicating between the smoke storage cavity 102, the air storage cavity 103, and the external air of the body 1. The main housing 11 has a baffle plate 1111 disposed at the front of the smoke storage cavity 102, and a jet port 110 is provided on the baffle plate 1111. The smoke generating component 2 includes a smoke generating assembly 21 disposed in the device cavity 101 for heating smoke oil into smoke, and an oil pump assembly 22 for pumping smoke oil into the smoke generating assembly 21. The main body 1 has a first passageway 105 connecting the equipment cavity 101 with the smoke storage cavity 102 and / or the air storage cavity 103. The output end of the smoke generating component 21 is connected to the first passageway 105. The jet driving component 3 includes a jet assembly 31 disposed in the main housing 11 and a driving component 32 for driving the jet assembly 31. When the jet assembly 31 is working, it can draw air from outside the main body into the air storage cavity 103 along the jet channel 104 and generate a pulsed airflow that is sprayed along the smoke storage cavity 102 toward the baffle plate 1111, thereby pushing the smoke and airflow in the smoke storage cavity 102 to be ejected from the jet port 110 to form a smoke ring. The driving component 32 can adjust the jet distance of the smoke ring by adjusting its start-stop frequency, speed, or running time.The automatic smoke ring machine of this embodiment uses a driving component 32 to drive the jet assembly 31 to generate a pulsed airflow, replacing the existing technology that relies on the elastic impact during the deformation of an elastic membrane to generate a pulsed airflow. During the operation of the jet assembly 31, external air is continuously drawn into the air storage chamber 103 along the jet channel 104, and this air in the air storage chamber 103 is converted into a pulsed airflow that is sprayed along the smoke storage chamber 102 towards the baffle plate 1111. The pulsed airflow pushes the smoke and airflow in the smoke storage chamber 102 to be ejected from the jet port 110 to the outside, forming a smoke ring. The automatic smoke ring ejection system achieves this by generating pulsed airflow without relying on component deformation. The jet assembly 31 provides a stable pulsed airflow intensity, ensuring a consistently stable smoke ring shape over a long period, thus extending the service life of the automatic smoke ring machine. Furthermore, since the smoke ring ejection distance is primarily determined by the impact force and duration of a single pulsed airflow within the smoke storage chamber 102, and the operating parameters of the drive assembly 32 directly affect these factors, the impact force and duration of a single pulsed airflow can be increased by adjusting the speed and operating time of the drive assembly 32, thereby increasing the smoke ring ejection distance. The ratio of the rotational speed to the running time of the moving component 32 is used to form different start-stop frequencies, thereby adjusting the pulse frequency, airflow duration, and airflow intensity of the pulsed airflow generated by the jet component 31. This, in turn, allows for a wide range of adjustment of the smoke ring jet distance, improving the consistency and controllability of smoke ring formation, and adapting to different usage scenarios such as small events and large stages. In addition, the output end of the smoke generating component 21 is connected to the first passage 105 on the body 1 that connects the equipment cavity 101 to the smoke storage cavity 102 and / or the air storage cavity 103. The smoke generated after being heated by the smoke generating component 21 in the equipment cavity 101 is directly sent into the smoke storage cavity 102 along its output end, or directly sent into the smoke storage cavity 102. The smoke oil enters the gas storage chamber 103 and then flows into the smoke storage chamber 102 through the jet channel 104. Under the action of the oil pump assembly 22, the smoke oil can be continuously pumped into the smoke generating assembly 21 according to actual needs, ensuring that the smoke generating assembly 21 continuously and stably produces high-concentration smoke. This high-concentration smoke can be better enveloped and pushed by the pulsed airflow generated by the jet assembly 31, forming a high-concentration, full-shaped, and clearly colored smoke ring with a clearer visual effect. At the same time, after the smoke ring is formed, the high-concentration smoke particles have strong cohesion and are not easily blown away by the external airflow, maintaining their complete shape in the air for a long time, which is conducive to forming long-distance smoke rings. According to the test, the smoke ring machine of this embodiment can emit smoke rings with a maximum diameter of 45cm and a jet distance of more than 15m. The smoke concentration is high and the continuous working time is long, making it suitable for special effects scenes such as large stages and outdoor commercial celebrations.

[0037] like Figure 2 , Figure 3As shown, in this embodiment, the jet assembly 31 is configured as a fan structure, capable of drawing in outside air along the jet channel 104 and generating an axial pulsed airflow that blows along the smoke storage chamber 102 toward the jet nozzle 110 during high-frequency start-stop rotation. The drive assembly 32 is connected to the fan structure for driving the fan structure to start and stop rotation at high frequencies. The fan structure is arranged coaxially with the jet nozzle 110 to ensure that the pulsed airflow is arranged along the central axis of the jet nozzle 110, avoiding airflow deviation that could lead to irregular smoke ring formation. In this embodiment, the fan structure is configured as a propeller, which is beneficial for ejecting high-intensity axial pulsed airflow. In other embodiments, the fan structure can also be configured as a fan or other jet-generating fan structure, or the jet assembly can also be configured as other jet-generating structures.

[0038] like Figure 6 As shown, in this embodiment, the jet assembly 31 includes a central hub 312 and several blades 311 connected around the central hub 312. The drive assembly 32 is configured as a drive motor, and the output shaft 321 of the drive assembly 32 is arranged coaxially with the jet nozzle 110. The central hub 312 is mounted and positioned on the output shaft 321 by a key structure and a locking nut, forming a rigid connection with the output shaft 321, and can rotate synchronously with the output shaft 321, making it less prone to slippage or freewheeling. Moreover, the jet assembly 31 directly adopts a connection structure in which the central hub 312 and the output shaft 321 are coaxially fixedly connected. Compared with some connection structures that use intermediate transmission structures such as transmission links between the jet assembly 31 and the output shaft 321, the structure is simpler and the power transmission is more direct and rapid. The blades 311 are evenly connected to the outer periphery of the central hub 312. In this embodiment, three blades are preferably provided, which simplifies the structure, ensures balanced force during rotation, and avoids vibration caused by uneven force, thus preventing the equipment from affecting its operational stability. In this embodiment, the blade 311 is configured as a long and thin strip structure, and is continuously twisted from one end near the central hub 312 to the other end away from the central hub 312. This can effectively improve the air intake and airflow pushing efficiency when the jet assembly 31 rotates, making the generated axial airflow more concentrated and stronger, while reducing airflow resistance, which is beneficial to improving the intensity of pulsed airflow.

[0039] like Figure 3 As shown, in this embodiment, the distance between the end of the blade 311 away from the central hub 312 and the central hub 312 is set to be greater than the radius of the injection port 110. This ensures that the radius of the axial pulse airflow generated by the rotation of the jet assembly 31 is greater than the radius of the injection port 110. This ensures that when the axial pulse airflow pushes the smoke and airflow in the smoke storage chamber 102 toward the injection port 110, it can be squeezed out of the injection port 110 to the outside under the obstruction of the inner circumferential sidewall of the injection port 110 to form a vortex-shaped smoke ring.

[0040] In this embodiment, the blade 311 is longer than 15cm, and the drive assembly 32 is a brushless motor, mounted on the first partition 14 via a brushless motor adapter. The jet drive component 3 also includes an electronic speed controller (ESC) structure 33 arranged within the equipment cavity 101. The ESC structure 33 is a professional brushless motor ESC. A circuit board assembly 51 is provided within the equipment cavity 101. The circuit board assembly 51 can receive manual adjustment signals or DMX control signals from the operator and output corresponding electrical signals to the ESC structure 33 according to a preset program or external instructions. The ESC structure 33 is electrically connected to the brushless motor and the circuit board assembly 51, and is used to adjust the start-stop frequency, speed, or running time of the brushless motor according to the electrical signals from the circuit board assembly 51 to adjust the jet distance of the smoke ring. In this embodiment, the brushless motor has the advantages of high speed, fast response, low inertia, and high power. Combined with the large-size blade 311, it can significantly improve the airflow thrust, making it more suitable for the high-frequency start-stop rotation of the jet assembly 31 to generate pulsed airflow. The smoke generating component 21 and the oil pump component 22 are also electrically connected to the circuit board component 51, which can adjust the amount of smoke generated to meet the smoke supply requirements in smoke ring jet scenarios. In other embodiments, the drive component 32 can also be configured as other drive motors or other drive structures that can provide high-frequency start-stop rotation functions.

[0041] like Figure 9 As shown, in this embodiment, a cooling structure 52 is also provided inside the device cavity 101. The electronically controlled switch (ECS) structure 33 is fitted into the cooling structure 52, which can efficiently dissipate heat from the ECS structure 33, preventing it from overheating and affecting its working accuracy or even burning out. Optionally, the cooling structure 52 is a liquid-cooled aluminum block with a coolant flow channel inside. A micro-cooling pump and heat dissipation pipe are connected externally. The coolant circulates along the flow channel under the drive of the cooling pump, carrying away the heat generated by the ECS structure 33. The back of the ECS structure 33 is attached to the front surface of the liquid-cooled aluminum block with thermally conductive silicone. The thermally conductive silicone has a high thermal conductivity, which can quickly transfer the heat generated by the ECS structure 33 to the liquid-cooled aluminum block. After being cooled by the circulating coolant, the ECS structure 33 is ensured to always operate within a suitable temperature range, improving its working stability and service life.

[0042] like Figure 6As shown, in this embodiment, the main housing 11 is provided with a first partition 14 and a second partition 13 arranged behind the first partition 14. The first partition 14 and the front part of the main housing 11 surround to form the smoke storage chamber 102, and the second partition 13 and the housing 12 surround to form the equipment chamber 101. The first partition 14, the second partition 13, the rear part of the main housing 11 and the front part of the housing 12 surround to form the air storage chamber 103. This allows the equipment chamber 101 to be independently separated, achieving physical isolation. This can prevent liquids such as water after the smoke evaporates in the smoke storage chamber 102 or the air storage chamber 103 from adhering to the surface of components such as the smoke generating component 21, oil pump component 22, electronic control structure 33, cooling structure 52, and circuit board component 51 in the equipment chamber 101, thus affecting the normal operation of the components and ensuring the stability of the automatic smoke ring machine. Furthermore, by providing a second partition 13 within the main housing 11, the equipment cavity 101 and the air storage cavity 103 are separated along the front-to-back direction, and the equipment cavity 101 is positioned behind the air storage cavity 103. This ensures that when the smoke in the air storage cavity 103 flows forward under the influence of the axial pulsed airflow or diffuses radially around the air storage cavity 103, the smoke mainly concentrates in front of the second partition 13, making it difficult for it to drift backward and intrude into the equipment cavity 101. This significantly reduces the risk of smoke drifting into the equipment cavity 101, which is beneficial for maintaining a relatively dry state inside the equipment cavity 101 for a long time. It is also more conducive to the long-term stable operation of components such as the smoke generating assembly 21, oil pump assembly 22, electronic control structure 33, cooling structure 52, and circuit board assembly 51 inside the equipment cavity 101. The first partition 14 helps to store the smoke in the smoke storage cavity 102, reducing the amount of smoke in the smoke storage cavity 102 that flows back to the air storage cavity 103 or the outside of the machine body 1 through the jet channel 104. In other embodiments, the gas storage cavity 103 may be formed directly by the first partition 14, the second partition 13 and the rear of the main housing 11.

[0043] like Figure 6As shown, in this embodiment, the jet channel 104 includes several third jet sections 1043 formed on the first partition 14. The drive assembly 32 is mounted on the first partition 14 using fasteners such as screws and bolts. Specifically, the first partition 14 includes a central base 141, a ring frame 142 arranged coaxially with the jet nozzle 110, and several support bars 143 connecting the central base 141 and the ring frame 142. The third jet sections 1043 are formed by surrounding two adjacent support bars 143 with the central base 141 and the ring frame 142. The jet assembly 31 and the drive assembly 32 are arranged on the side of the central base 141 away from the jet nozzle 110, and the drive assembly 32 is mounted on the central base 141, while the jet assembly 31 is mounted on the output shaft 321 of the drive assembly 32. The pulsed airflow generated by the high-frequency start-stop rotation of the jet assembly 31 can be diverted by the support bar 143 and flow into the smoke storage chamber 102 through each of the third jet sections 1043. The jet channel 104 includes several fourth jet sections 1044 located in the smoke storage chamber 102 and respectively arranged between each of the third jet sections 1043 and the jet nozzle 110. After being diverted by the support bar 143, the airflow can flow into the smoke storage chamber 102 along each of the fourth jet sections 1044 and be evenly distributed along the cross-section of the smoke storage chamber 102, improving the regularity of the smoke ring formation. In some other embodiments, the jet assembly 31 and the drive assembly 32 can also be arranged on the central base 141 on the side near the jet nozzle 110.

[0044] In this embodiment, the ring frame 142 includes an annular partition 1421 and a cylindrical structure 1422 extending forward from the inner periphery of the annular partition 1421. The central base 141 is connected to the front end of the cylindrical structure 1422 through each support bar 143. The jet assembly 31 and the drive assembly 32 are arranged inside the cylindrical structure 1422, thereby increasing the gas storage space of the gas storage chamber 103. The pulsed airflow generated when the jet assembly 31 starts and stops rotating at high frequency can be guided along the cylindrical structure 1422 to each third jet section 1043. The cylindrical structure 1422 plays a preliminary guiding role for the pulsed airflow generated by the jet assembly 31, so that the airflow flows along the axial direction of the cylindrical structure 1422, preventing the airflow from drifting to the surroundings and improving the concentration of the airflow. Subsequently, the pulsed airflow flows into the smoke storage chamber 102 through the third jet section 1043 at the front end of the cylindrical structure 1422, ensuring the axial stability of the airflow. The cylindrical structure 1422, the central base 141, and each support bar 143 are integrally formed, resulting in a stable structure. The cylindrical structure 1422 is detachably connected to the annular partition 1421. Optionally, the cylindrical structure 1422 is detachably connected to the annular partition 1421 via a bracket connecting ring 144 extending vertically from its rear end toward its outer periphery. This allows the cylindrical structure 1422, the central base 141, each support bar 143, the drive assembly 32, and the jet assembly 31 to be disassembled as a whole relative to the annular partition 1421, facilitating the later maintenance of the drive assembly 32 and the jet assembly 31.

[0045] like Figure 2 As shown, in this embodiment, the first partition 14 is spaced apart and arranged in front of the second partition 13. The jet channel 104 includes a second jet section 1042 arranged between the first partition 14 and the second partition 13, and several first jet sections 1041 arranged on the outer peripheral sidewall of the main housing 11, each communicating with the second jet section 1042. The first jet sections 1041 are arranged behind the first partition 14 and serve as intake ports for external air. Several first jet sections 1041 are arranged circumferentially along the outer peripheral sidewall of the main housing 11 and are all connected to the second jet sections 1042, ensuring that external air can be simultaneously drawn in from multiple directions, increasing the intake volume and meeting the intake requirements of the high-speed rotation of the jet assembly 31. The second jet section 1042 is the space between the first partition 14 and the second partition 13, arranged in the front-rear direction, serving as a temporary storage space for airflow and a guide channel connecting each first jet section 1041 and the third jet section 1043. External air can be sprayed onto the nozzle 110 via the jet assembly 31 along the flow paths of the first jet section 1041, the second jet section 1042, the third jet section 1043, and the fourth jet section 1044. During the operation of the jet assembly 31, external air can be continuously drawn in as needed, and the flow path is basically arranged along the axis of the nozzle 110, which is beneficial to air flow.

[0046] like Figure 4 , Figure 5As shown, in this embodiment, the main housing 11 includes a smoke storage shell 111 and an air intake shell 112 connected between the smoke storage shell 111 and the front part of the housing 12. The smoke storage shell 111 includes a baffle plate 1111 and a smoke storage side plate 1112 extending rearward from the periphery of the baffle plate 1111. The baffle plate 1111, the smoke storage side plate 1112, and the first partition plate 14 surround to form the smoke storage cavity 102. The air intake shell 112 includes the first partition plate 14 and an air intake side plate 1121 extending rearward from the periphery of the first partition plate 14. The air intake side plate 1121 is connected between the periphery of the first partition plate 14 and the housing 12. A first jet section 1041 is disposed on the air intake side plate 1121. The first partition plate 14, the air intake side plate 1121, the second partition plate 13, and the housing 12 surround to form the air storage cavity 103. In this embodiment, the air intake shell 112, the first partition 14, the drive assembly 32, and the jet assembly 31 can be installed or removed from the housing 12 as a whole by means of an air intake connecting ring 1122 extending vertically from the rear end of the air intake side plate 1121 toward its inner circumference and a housing connecting ring 123 protruding on the outer circumference of the housing 12, which facilitates assembly and subsequent maintenance. The smoke storage shell 111 can be installed or removed from the air intake shell 112 by means of a smoke storage connecting ring 1113 extending vertically from the rear end of the smoke storage side plate 1112 toward its inner circumference and an annular partition 1421 of the first partition 14 of the air intake shell 112, and the smoke storage connecting ring 1113 can be detachably connected to the front side of the first partition 14, which facilitates assembly and subsequent maintenance, and also facilitates the replacement of smoke storage shells 111 with different sized jet nozzles 110, thereby spraying smoke rings of different sizes. The housing connecting rings are arranged at intervals along 123 behind the second partition 13, so that the rear part of the air intake side plate 1121 is located behind the second partition 13. On the one hand, this can shorten the overall length of the body 1, making the structure more compact and reducing the length space occupied. It also improves the support stability of the air intake shell 112 on the housing 12. On the other hand, the first jet section 1041 is configured as a strip-shaped hole opened in the front-rear direction on the air intake side plate 1121. The rear part of the strip-shaped hole is located behind the second partition 13. The second jet section 1042 includes an air intake area arranged between the rear part of the air intake side plate 1121 and the outer peripheral side wall of the housing 12 and communicating with the rear part of the strip-shaped hole. This can increase the length of the strip-shaped hole and increase the air intake volume to meet the air intake volume requirements of the jet assembly 31 for high-frequency start-stop rotation. In some other embodiments, the air storage cavity 103 can also be formed by the first partition 14, the air intake side plate 1121 and the second partition 13.

[0047] In this embodiment, the housing 12 includes a housing panel 121 spaced apart on the rear side of the second partition 13 and a housing side panel 122 connected between the periphery of the second partition 13 and the housing panel 121. The second partition 13, the housing side panel 122, and the housing panel 121 surround to form the device cavity 101. The second partition 13 is detachably connected to a housing mounting ring 124 extending vertically from the front end of the housing side panel 122 toward its inner periphery, allowing it to be installed or removed relative to the housing 12. The second partition 13 is positioned in front of the housing mounting ring 124 to facilitate the assembly or subsequent maintenance of the second partition 13.

[0048] like Figure 1 , Figure 4 As shown, this embodiment also includes a support base 71, which is connected to the air intake side plate 1121 by fasteners such as screws and bolts. The emission angle of the smoke ring can be adjusted by adjusting the relative angle between the air intake side plate 1121 and the support base 71 to adapt to different usage scenarios. In this embodiment, the support base 71 includes a support base plate 711 that contacts the surface of the mounting medium such as the ground or stage surface, and support side plates 712 that extend upward from both ends of the support base plate 711. The upper ends of the two support side plates 712 are connected to both sides of the air intake side plate 1121 by fasteners such as slotted screws, which facilitates the adjustment of the emission angle of the smoke ring.

[0049] In this embodiment, the smoke storage side plate 1112 is a cylindrical structure, the housing side plate 122 is a cylindrical structure, and the air intake side plate 1121 is a cylindrical structure. The air intake side plate 1121 has guide planes on both sides that respectively conform to the surfaces of the two support side plates 712. This serves two purposes: firstly, it guides the air intake side plate 1121 when adjusting the smoke ring emission angle; secondly, it increases the contact area between the air intake side plate 1121 and the support base 71, improving the stability of the support base 71 in supporting the machine body 1. The support base plates 711 are spaced apart below the air intake side plates 1121 to avoid obstructing part of the first jet section 1041 at the bottom of the air intake side plate 1121.

[0050] like Figure 1 , Figure 4As shown, this embodiment also includes a handle structure 72, which is connected to the air intake side plate 1121 by fasteners such as screws and bolts, facilitating the lifting and moving of the machine body 1. In this embodiment, the handle structure 72 includes a grip portion 721 spaced apart from the outer surface of the machine body 1 and handle connecting plates 722 extending downward from both ends of the grip portion 721. The lower ends of the two handle connecting plates 722 are connected to both sides of the air intake side plate 1121 by fasteners such as screws and bolts. The handle connecting plate 722 includes a first handle connecting portion 7221 arranged on the outside of the air intake side plate 1121 and a second handle connecting portion 7222 connecting the first handle connecting portion 7221 and the grip portion 721. The second handle connecting portion 7222 and the grip portion 721 are arranged on the front side of the air intake side plate 1121 to avoid obstructing part of the first jet section 1041 on the upper part of the air intake side plate 1121. In this embodiment, the support side plate 712 and the second handle connection part 7222 are connected to the air intake side plate 1121 by the same fastener such as a slotted screw, which facilitates assembly. The fastener is fitted with a flanged copper sleeve 73 and a flexible washer 74. The support side plate 712 is fitted onto the flanged copper sleeve 73, reducing wear on the support side plate 712 from the fastener. The flexible washer 74 is stacked between the inner wall of the support side plate 712 and the outer wall of the second handle connection part 7222, reducing wear on the support side plate 712 from the second handle connection part 7222 and increasing the stability of angle adjustment and fixing. The air intake side plate 1121 includes an upper air intake side plate and a lower air intake side plate detachably connected to the lower side of the upper air intake side plate, facilitating the assembly of the first partition 14, the drive assembly 32, and the jet assembly 31. The two sets of support side plates 712 and the second handle connection part 7222 are respectively connected to both sides of the upper air intake side plate.

[0051] like Figure 3 , Figure 5 As shown, this embodiment also includes a lighting structure 4, which is installed on the front side of the second partition 13. The lighting structure 4 can scatter its emitted light onto the smoke inside the smoke storage chamber 102 to form smoke with the color of the light, and can also scatter its emitted light onto the smoke rings near the nozzle 110 to form smoke rings with the color of the light, making the smoke rings more dazzling and enhancing the visual effect. The smoke storage shell 111 is made of transparent material, allowing the smoke and light color inside to be transmitted to the outside, further enhancing the visual effect.

[0052] like Figure 3 As shown, in this embodiment, the nozzle 110 is configured as a circular structure to form a circular smoke ring. The light structure 4 is configured as a ring structure arranged coaxially with the nozzle 110, and the radius of the light structure 4 is set to be smaller than the radius of the nozzle 110, so that more light can be scattered through the nozzle 110 onto the smoke ring. The light structure 4 is bonded to the front surface of the second partition 13 with adhesive.

[0053] like Figure 5As shown, in this embodiment, the first passageway 105 includes a second through hole formed on the second partition 13 and communicating with the equipment cavity 101 and the gas storage cavity 103, and a first through hole formed on the first partition 14 and communicating with the gas storage cavity 103 and the smoke storage cavity 102. The output end of the smoke generating component 21 is configured as a conveying pipe connected to the second through hole and the first through hole for easy connection. The smoke can be directly sent into the smoke storage cavity 102 by the conveying pipe passing through the second through hole and the first through hole in sequence. In other embodiments, only the second through hole may be provided, and the smoke may be directly sent into the smoke storage cavity 102 by the conveying pipe passing through the second through hole and other parts such as the machine box side plate 122 and the smoke storage side plate 1112 in sequence, or the smoke may be directly sent into the gas storage cavity 103 by the conveying pipe passing through the second through hole in sequence; or only the first through hole may be provided, and the smoke may be directly sent into the smoke storage cavity 102 by the conveying pipe passing through other parts such as the machine box side plate 122 and the smoke storage side plate 1112 in sequence and the first through hole in sequence. In the various arrangements of the first passage 105, a sealing gasket is provided at the connection position between the first passage 105 and the output end of the smoke generating component 21, such as a pipe fitting or connector, to prevent smoke from flowing into the equipment cavity 101 along the first passage 105 and affecting the normal operation of the components inside the equipment cavity 101.

[0054] In this embodiment, condensate is generated during the pre-cooling of smoke in the smoke storage chamber 102 or the air storage chamber 103. A drain component 61 is arranged in the smoke storage chamber 102. The body 1 has a second passageway 106 connecting the equipment chamber 101 with the smoke storage chamber 102 and the air storage chamber 103. The output end of the drain component 61, such as a pipe, passes through the second passageway 106 and connects to a drain connector on the housing panel 121 of the housing 12, enabling timely recovery of condensate in the smoke storage chamber 102. The second passageway 106 is located on the second partition 13 and the first partition 14. A sealing gasket is provided at the connection point between the second passageway 106 and the output end of the drain component 61 (such as a pipe or connector) to prevent smoke from flowing into the equipment chamber 101 along the second passageway 106 and affecting the normal operation of the components inside the equipment chamber 101. In other embodiments, the second passageway 106 is also located on other structural parts of the body 1, such as the housing side panel 122 and the air inlet side panel 1121.

[0055] In this embodiment, the body 1 is provided with a third passage 107 connecting the equipment cavity 101 and the main housing 11. The output end of the electronic control structure 33 passes through the third passage 107 and is connected to the drive assembly 32.

The connection position of the output end of the electronic control structure 33, such as the wire, is provided with a sealing gasket to prevent smoke from flowing into the equipment cavity 101 along the third passage 107 and affecting the normal operation of the internal components of the equipment cavity 101. In other embodiments, the third passage 107 may only be provided on the second partition 13, or it may be provided on other parts of the body 1, such as the casing side plate 122 and the air intake side plate 1121.

[0056] like Figure 7 , Figure 8 As shown, in this embodiment, the smoke generating assembly 21 includes a heater 211 and a fixed shell 212 that is wrapped and fixed outside the heater 211. The heater 211 is used to heat the smoke oil and convert it into smoke. The space between the fixed shell 212 and the heater 211 is filled with heat insulation material for heat insulation, forming a heat insulation layer, reducing heat loss, improving heating efficiency, and reducing the heat transferred to the circuit board assembly 51, oil pump assembly 22, electronic control structure 33, cooling structure 52 and other structures.

[0057] In this embodiment, a first mounting bracket 15 is connected to the rear side of the second partition 13. The smoke generating assembly 21 is arranged below and connected to the first mounting bracket 15, and the oil pump assembly 22 is arranged above and connected to the first mounting bracket 15. This facilitates the assembly or disassembly of the smoke generating assembly 21 and the oil pump assembly 22. Simultaneously, the first mounting bracket 15 can insulate against the heat generated by the smoke generating assembly 21, reducing the heat transferred from the smoke generating assembly 21 to the oil pump assembly 22. The input end of the oil pump assembly 22 is connected to the oil pipe connector on the housing panel 121 via pipe fittings, connectors, and other structures, while the output end is connected to the input end of the smoke generating assembly 21 via a stainless steel capillary tube and other structures. The oil pipe connector and the drain connector can be set as a single connector to simplify the structure and facilitate the recovery of condensate into an external oil tank. Alternatively, they can be set as separate connectors for separate use.

[0058] In this embodiment, the first mounting bracket 15 is connected between the second partition 13 and the housing panel 121, and is also connected to both the second partition 13 and the housing panel 121, thereby improving the stability of the support for the first mounting bracket 15. The first mounting bracket 15 includes a first connecting plate 151 that is fitted and detachably connected to the second partition 13, a second connecting plate 152 that is fitted and detachably connected to the housing panel 121, and a mounting bracket 153 connected between the first connecting plate 151 and the second connecting plate 152. The smoke generating assembly 21 is arranged on the lower side of the mounting bracket 153, and the oil pump assembly 22 is arranged on the upper side of the mounting bracket 153, resulting in a compact spatial arrangement.

[0059] In this embodiment, the mounting bracket 153 includes a mounting plate 1531 spaced apart on the front side of the housing panel 121, a mounting plate 1532 connected between the upper end of the mounting plate 1531 and the connecting plate 151, and a mounting plate 1533 connected between the two sides of the mounting plate 1531 and the connecting plate 152. The top side of the smoke generating assembly 21 is spaced apart from the mounting plate 1532, the front side is spaced apart from the second partition 13 and has a plurality of front leveling columns 2121 supporting the smoke generating assembly 21 and the second partition 13, and the rear side is spaced apart from the mounting plate 1531 and has a plurality of rear leveling columns 2122 supporting the smoke generating assembly 21 and the mounting plate 1531. The front leveling columns 2121 are detachably connected to the second partition 13, and the rear leveling columns 2122 are detachably connected to the mounting plate 1531, so that the smoke generating assembly 21 is stably mounted on the first mounting bracket 15. In this embodiment, the top, front, and rear sides of the smoke generating assembly 21 are arranged at intervals with the first mounting bracket 15, which can improve the heat insulation effect of the first mounting bracket 15 on the smoke generating assembly 21. The front leveling column 2121 is used to stably limit the interval distance between the front side of the smoke generating assembly 21 and the second partition 13, and the rear leveling column 2122 is used to stably limit the interval distance between the rear side of the smoke generating assembly 21 and the mounting plate 1531. At the same time, the front leveling column 2121 and the rear leveling column 2122 are also used to connect the smoke generating assembly 21 and the first mounting bracket 15, which has the effect of multiple uses.

[0060] In this embodiment, a second mounting bracket 16 is connected to the rear side of the second partition 13. A switching power supply 53 is mounted on the second mounting bracket 16. The switching power supply 53 provides a stable current and voltage. The input terminal of the electronic speed controller 33 is connected to the output terminal of the switching power supply 53, and the input terminal of the switching power supply 53 is connected to the circuit board assembly 51. The second mounting bracket 16 is arranged above the oil pump assembly 22, that is, away from the smoke generating assembly 21, to reduce the heat transferred from the smoke generating assembly 21 to the switching power supply 53. The circuit board assembly 51 is arranged above the first mounting bracket 15 and mounted inside the housing panel 121 to reduce the heat transferred from the smoke generating assembly 21 to the circuit board assembly 51. Several operating components electrically connected to the circuit board assembly 51 are provided on the outside of the housing panel 121, facilitating manual adjustment of the smoke ring spray distance by the operator. Several external connectors electrically connected to the circuit board assembly 51 are also provided on the outside of the housing panel 121, facilitating adjustment of the smoke ring spray distance by the operator through external devices.

[0061] like Figure 4 , Figure 5 , Figure 9As shown, this embodiment also includes a first cooling fan 54, which is arranged within the area formed by the mounting plate 1531 and the connecting plate 152 and installed inside the chassis panel 121, resulting in a compact structure. A first vent 1221 is provided on a portion of the chassis side panel 122 near the smoke generating assembly 21, and a first air outlet 1211 is provided on the chassis panel 121 opposite to the first cooling fan 54. The mounting plate 1531, the first vent 1221, and the first cooling fan 54 are arranged at intervals to form a first air guide channel for external air to be drawn into the first cooling fan 54 through the first vent 1221 and blown out through the first air outlet 1211. This quickly blows the heat emitted by the smoke generating assembly 21 to the outside, preventing heat transfer to the circuit board assembly 51, oil pump assembly 22, switching power supply 53, ESC structure 33, and other structures, thus affecting normal operation. The first vent 1221 is configured as a strip-shaped hole opened in the front-rear direction on the side plate 122 of the housing, and the front part of the strip-shaped hole is located between the rear side of the second partition 13 and the edge of the housing connecting ring 123; the intake side plates 1121 are arranged at intervals on the outer periphery of the side plate 122 of the housing, and a portion of the first jet section 1041 is arranged close to the first vent 1221 and configured as a strip-shaped hole opened in the front-rear direction on the intake side plate 1121, and the rear part of the strip-shaped hole is located between the rear side of the second partition 13 and the edge of the housing connecting ring 123, so that the rear part of the first jet section 1041 and the front part of the first vent 1221 are positioned close to each other. A first air intake section is formed to allow air to flow from outside the machine body into the equipment cavity 101; the rear part of the first vent 1221 is located between the machine box connecting ring 123 and the machine box panel 121, so that a second air intake section is formed at the rear of the first vent 1221 to allow air from outside the machine body to flow into the equipment cavity 101. This allows part of the air drawn in through the first jet section 1041 to flow into the smoke storage cavity 102 along the second jet section 1042 to form a pulsed airflow, and the other part to flow into the equipment cavity 101 for ventilation and heat dissipation of the internal components of the equipment cavity 101. The first jet section 1041 has the effect of multiple uses.

[0062] In this embodiment, a second cooling fan 55 is also included. The second cooling fan 55 is arranged near the switching power supply 53 and installed inside the side plate 122 of the chassis. The side plate 122 of the chassis is provided with a second vent 1222 arranged opposite to the second cooling fan 55. A second air guide channel is formed between the first mounting plate 1531, the second mounting plate 1532, the oil pump assembly 22, the switching power supply 53, and the circuit board assembly 51, so that air is drawn into the second cooling fan 55 through the second vent 1222 and blown out to the outside through the first air outlet 1211, thereby quickly blowing the heat generated by the switching power supply 53 and the circuit board assembly 51 to the outside. In other embodiments, the second cooling fan 55 can also be used to quickly blow the heat generated by the switching power supply 53 and the circuit board assembly 51 to the outside through the second vent 1222.

[0063] like Figure 9 As shown, in this embodiment, a third mounting bracket 17 is also arranged inside the side panel 122 of the housing. The electronic control structure 33 and the cooling structure 52 are mounted on the third mounting bracket 17, facilitating the assembly or disassembly of the electronic control structure 33 and the cooling structure 52. The third mounting bracket 17 includes a fixing plate 171 arranged inside the side panel 122 of the housing and a cover plate 172 detachably connected to the inside of the fixing plate 171. The electronic control structure 33 and the cooling structure 52 are stacked with the fixing plate 171 and pressed and fixed between the fixing plate 171 and the cover plate 172, facilitating assembly or disassembly. The third mounting bracket 17 is detachably connected to the inside of the front panel 121 of the housing via a fixed connecting line 173 extending vertically inward from the rear end of the fixing plate 171.

[0064] In summary, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the present invention.
