Description
Technical Field
[0001] This utility model relates to the field of smoke generator technology, and specifically to a smoke generator. Background Technology
[0002] A pure water smoke generator is a device that can convert pure water into tiny water droplets to create a smoke-like effect. Its working principle is mainly based on heating or ultrasonic vibration technology. The smoke is mainly composed of water vapor and water droplets. The ultrasonic smoke generator uses high-frequency vibration to cause water molecules to disperse into tiny water droplets, thereby forming smoke.
[0003] However, current ultrasonic smoke generators face several pressing technical challenges in practical applications. During liquid atomization, the atomized particles tend to agglomerate during flow. Furthermore, if the tiny particles formed after atomization are not promptly discharged, they will gradually settle under gravity over time, significantly impacting the atomization effect and leading to reduced atomization efficiency and insufficient particle size uniformity. This not only affects the sustainability of the smoke effect but also limits the equipment's application range and performance stability to some extent.
[0004] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content
[0005] In view of this, the purpose of this utility model is to provide a smoke generator.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A smoke generator, comprising:
[0008] case;
[0009] A water tank is disposed within the housing. The mist outlet at the top of the water tank is connected to a mist outlet pipe that penetrates the housing and communicates with the outside. An atomizer and a guide plate are installed inside the water tank. The atomizer is located at the bottom of the water tank. The guide plate is located between the atomizer and the mist outlet, dividing the water tank into a liquid storage space and a mist outlet space. Multiple guide channels are provided on the guide plate. The atomized particles generated by the atomizer in the liquid storage space pass through each of the guide channels and enter the mist outlet space, and are discharged through the mist outlet pipe.
[0010] A misting fan is embedded in the wall of the water tank. The air outlet of the misting fan is set to face the virtual pipe wall that extends virtually into the water tank from the misting pipe. Its air delivery trajectory extends laterally to the area below the misting pipe, and the atomized particles are guided to the misting outlet by directional airflow.
[0011] The air guide plate is located below the air outlet of the mist-discharging fan;
[0012] A control module is disposed on the housing, and the control module is electrically connected to the atomizer and the mist delivery fan.
[0013] Preferably, at least a portion of the flow channel tends to be horizontally close to the mist outlet from bottom to top.
[0014] Preferably, the flow channel is an arc-shaped channel from bottom to top, and the mist outlet at the top of the water tank is horizontally away from the air outlet of the mist-discharging fan.
[0015] Preferably, the opening of the flow channel is elongated or perforated.
[0016] Preferably, a water level detection sensor is installed at the preset liquid level warning line at the bottom of the water tank, and the water level detection sensor is electrically connected to the control module.
[0017] Preferably, the water level detection sensor is an electrode probe.
[0018] Preferably, the bottom of the housing is provided with a base, the water tank is installed on the base, and a drain outlet is provided on the bottom wall or the side wall near the bottom wall of the water tank. The drain outlet is connected to a drain pipe that passes through the base and the housing and communicates with the outside. A valve is installed at the end of the drain pipe that communicates with the outside.
[0019] Preferably, a heat dissipation device is installed in the space between the shell and the water tank, and the heat dissipation device is electrically connected to the control module.
[0020] Preferably, the housing has heat dissipation holes at the positions corresponding to the heat dissipation device.
[0021] Preferably, a temperature sensor is installed in the space between the housing and the water tank, and the temperature sensor is electrically connected to the control module.
[0022] Compared with existing technologies, the beneficial effects of this invention are as follows: By coordinating the work of the guide plate and the atomizer, the mist exit path of the atomized particles is optimized, while preventing particle aggregation and optimizing droplet size distribution, resulting in more uniform and fine smoke particles. The optimized smoke particles are then rapidly diffused to the target area by the mist-dispensing fan, thereby improving the efficiency of mist output from the outlet and preventing particle settling. Therefore, this invention can produce high-quality smoke effects to meet the needs of scenarios with high smoke quality requirements. Furthermore, the inclusion of safety protection mechanisms, such as overheat protection and water shortage protection, effectively avoids potential safety hazards during equipment operation, significantly improving equipment safety and stability, thus ensuring the normal operation of the equipment and the safety of personnel.

[0027] The technical solution of this utility model will now be clearly and completely described through specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0028] See appendix Figure 1 As shown, this application discloses a smoke generator designed to efficiently and stably convert liquids such as water into water mist particles, optimize droplet size distribution for greater uniformity, prevent agglomeration, improve atomization efficiency, and quickly deliver the mist to the target area via a fan. Multiple safety protection mechanisms, such as overheat protection and water shortage protection, ensure the coordinated operation of all components and guarantee normal operation under various environments. This application comprises key components including a housing 1, a water tank 2, an atomizer 3, a mist-delivering fan 4, a control module 6, and a guide plate 5. These components work together to achieve efficient smoke generation and stable operation. The water tank 2 is built into the housing 1, providing water storage for the entire smoke generator. The atomizer 3 is installed at the bottom of the water tank 2 and can be a piezoelectric atomizer, ultrasonic atomizer, etc. For example, the working principle of a piezoelectric atomizer utilizes the inverse piezoelectric effect of piezoelectric ceramics. When an alternating electric field is applied to the piezoelectric ceramic, it generates mechanical vibration, thereby efficiently atomizing the water in the water tank 2 into fine particles. This atomization method has advantages such as high atomization efficiency and fine particles.
[0029] The top of the water tank 2 is equipped with a mist outlet 24, which is connected to a mist outlet pipe 21. The mist outlet pipe 21 passes through the housing 1 and communicates with the outside. When adding liquid to the equipment, water can be added to the water tank 2 through the mist outlet pipe 21. Of course, the water tank 2 can also be equipped with an independent water inlet. When the equipment is working, the mist outlet pipe 21 is responsible for transporting the atomized particles generated in the water tank 2 to the outside. A mist-dispensing fan 4 is embedded in the wall of water tank 2. The air outlet of the mist-dispensing fan 4 is set to face the virtual pipe wall that extends virtually into the water tank from the mist outlet pipe 21. Its airflow trajectory extends laterally to the area below the mist outlet pipe 21. Through directional airflow, it guides the atomized particles to the mist outlet 24. When the mist-dispensing fan 4 is running, its air outlet faces the virtual pipe wall that extends virtually into the water tank from the mist outlet pipe. This can be a horizontal or upward orientation, generating a slightly lateral or horizontally upward airflow that transports the atomized particles to the side where the mist outlet 24 is located. This accelerates the discharge speed of the atomized particles, improves the delivery efficiency of the atomized particles to the mist outlet 24, and ensures that the atomized particles can quickly reach the target area. The mist-dispensing fan 4 can be a fan, such as an axial flow fan. The control module 6 adjusts the airflow as needed to control the water mist diffusion range. No specific limitations are made here.
[0030] Inside the water tank 2, a guide plate 5 of a certain thickness is installed on the discharge path of the atomized particles generated by the atomizer 3. At the same time, the guide plate 5 is located below the air outlet and mist outlet 24 of the mist fan 4 and above the atomizer 3. The guide plate 5 divides the water tank 2 into a liquid storage space and a mist outlet space. During operation, the guide plate 5 is above the liquid surface. Multiple guide channels 51 are opened on the guide plate 5 to form a discharge path along the atomized particles. The atomized particles pass through each guide channel 51 and are discharged from the housing 1 through the mist outlet pipe 21.
[0031] At least a portion of the flow channel 51 extends horizontally from bottom to top towards the mist outlet 24. The flow channel 51 provides a specific discharge path for the atomized particles. After the atomizer 3 generates atomized particles, their movement within the water tank 2 is relatively chaotic. The flow guide 5 guides these particles to flow orderly towards the mist outlet 24, preventing disorderly collisions and aggregation within the water tank 2, and guiding the output particles to move more directionally, thereby improving mist output efficiency. On the other hand, it prevents atomized particles from agglomerating and settling. Since atomized particles are prone to agglomeration due to collisions, the large agglomerated particles accelerate their settling. The flow guide 5 disrupts the potential agglomeration trajectory of the atomized particles, keeping them relatively dispersed during flow. This prolongs the suspension time of the atomized particles, allowing the smoke to diffuse more evenly and stably to the outside of the housing 1, ensuring the quality of the smoke effect. Preferably, the mist outlet 24 at the top of the water tank 2 is horizontally away from the air outlet of the mist-discharging fan 4. For example, the air outlet of the mist-discharging fan 4 is on one side wall of the water tank 2, and the mist outlet 24 is opened at the top near the opposite side wall of the water tank 2. Preferably, the guide channel 51 is an arc-shaped channel from bottom to top. Preferably, the arc-shaped channel bends towards the side of the mist outlet 24, that is, the tangent of the arc-shaped channel points to the area below the mist outlet 24. This arc-shaped design can better guide the airflow and the movement direction of particles, enhancing the guiding effect. Preferably, the opening of the guide channel 51 can be designed as a long strip or a perforated structure according to actual needs to adapt to different application scenarios and smoke generation requirements. For example, in scenarios with high requirements for smoke particle density, a perforated guide channel can be used; in scenarios with high requirements for smoke diffusion speed, a long strip guide channel may be more suitable. Optionally, the guide tube 5 can be coated with a hydrophobic coating.
[0032] The control module 6 is mounted on the housing 1. The atomizer 3 and the mist-delivering fan 4 are both electrically connected to the control module 6 and are used to control their operation. The control module 6 is the core control unit of the entire smoke generator. It can use a microcontroller as its control core and is equipped with corresponding drive circuits and sensor interface circuits. The control module 6 can precisely adjust various operating parameters of the smoke generator according to user needs and the device's operating status. Users can input commands to the control module 6 through the control panel (such as buttons, knobs, or a touchscreen). The control module 6 controls the power of the atomizer 3 according to these commands, thereby adjusting the amount and size of atomized particles. It also controls the rotation speed of the mist-delivering fan 4 to achieve precise control of the smoke diffusion speed and range.
[0033] To ensure the safe and stable operation of the equipment, this smoke generator is equipped with a series of safety protection devices, including a water level detection sensor 8, a heat dissipation device 7, and a temperature sensor 9. The water level detection sensor 8 is located at the bottom of the water tank 2, installed at the preset liquid level warning line, and is electrically connected to the control module 6. Preferably, the water level detection sensor 8 uses an electrode probe, which works by utilizing the conductivity of water to determine the water level. When the water tank 2 is full, the conductivity of the water makes the circuit between the electrodes continuous. When the water level is below the warning line, the circuit is broken, and the water level detection sensor 8 sends a continuity or disconnection signal to the control module 6. Upon receiving the signal, the control module 6 takes appropriate measures, such as stopping the equipment from working, preventing the atomizer 3 from dry burning in a water shortage state, and effectively protecting the safety of the equipment. It is understood that the electrode probe can be arranged at multiple points to monitor preset liquid level warning lines at different liquid levels. The heat dissipation device 7 is located between the housing 1 and the water tank 2 and is electrically connected to and controlled by the control module 6. Preferably, during installation, the housing 1 has ventilation holes corresponding to the location of the heat dissipation device 7. When the equipment generates heat during operation, the heat dissipation device 7 can be activated in time to dissipate the heat through the ventilation holes, ensuring that the internal temperature of the equipment is within the normal range and avoiding overheating that could affect the performance and lifespan of the equipment. Here, the heat dissipation device 7 can be a cooling fan. The temperature sensor 9 is also located between the housing 1 and the water tank 2. When the temperature sensor 9 detects that the temperature does not exceed the set temperature safety threshold, the control module controls the heat dissipation device to work normally. When the temperature sensor 9 detects that the temperature exceeds the set temperature safety threshold, it will immediately trigger the protection mechanism. At this time, the control module 6 will respond quickly, controlling the equipment to stop, immediately cutting off the power supply to each electrical component, or reducing the power output, while activating the heat dissipation device 7 to assist in cooling, and promptly alerting the user through indicator lights or alarm devices to ensure the safety of the equipment and personnel.
[0034] For a better option, see the appendix. Figure 1 As shown, a base 10 is provided at the bottom of the housing 1, and a water tank 2 is installed on the base 10. A drain outlet 25 is provided on the bottom or side wall near the bottom of the water tank 2. The drain outlet 25 is connected to a drain pipe 22 that passes through the base 10 and the housing 1 and is connected to the outside. For example, when the drain outlet 25 is on the side wall of the water tank 2, the drain pipe 22 can directly pass through the housing 1; when the drain outlet 25 is at the bottom of the water tank, the drain pipe 22 passes through the base 10 and the housing 1. A valve 23 is installed at the outlet of the drain pipe 22 to facilitate the drainage of water accumulated in the water tank 2. During equipment maintenance or cleaning, water can be drained by opening the valve 23, improving the convenience of equipment maintenance.
[0035] As one feasible approach, the workflow of a smoke generator is as follows:
[0036] When the smoke generator is powered on, the control module 6 first starts and performs a self-test program to initially check the working status of each component. After confirming that all components are normal, the control module 6 begins to monitor the signals of the water level sensor 8 and the temperature sensor 9 in real time. If the water level sensor 8 detects that the water level in the water tank 2 is within the normal range, the control module 6 controls the heat dissipation module and the atomizer 3 to start working according to the parameters preset by the user. Driven by the control module 6, the piezoelectric atomizer 3 atomizes the water in the water tank 2 into tiny atomized particles. At the same time, the control module 6 controls the mist delivery fan 4 to start and operate at the set speed. The airflow generated by the mist delivery fan 4 blows the atomized particles towards the mist outlet pipe 21. During the transmission of the atomized particles, the guide channel 51 on the guide plate 5 plays a role in guiding the atomized particles to flow orderly towards the mist outlet 24, avoiding particle agglomeration and sedimentation, so that the atomized particles can be diffused more evenly into the external environment through the mist outlet pipe 21. During equipment operation, temperature sensor 9 continuously monitors the temperature between the housing 1 and the water tank 2. Once temperature sensor 9 detects that the temperature exceeds the set safety threshold, it immediately sends a signal to control module 6. Upon receiving the signal, control module 6 quickly activates the overheat protection mechanism, immediately shutting down the equipment, cutting off the power supply to all electrical components, or reducing power output to prevent damage from overheating. Simultaneously, control module 6 controls the heat dissipation device 7 to continue operating, accelerating heat dissipation through the ventilation holes to assist in cooling the equipment. Furthermore, control module 6 will promptly alert the user via indicator lights or alarm devices, informing them of the overheating situation and reminding them to take appropriate measures. If water level sensor 8 detects that the water level is below the safety line, it will also send a signal to control module 6. Upon receiving the signal, control module 6 immediately stops the equipment to prevent the atomizer 3 from dry burning and ensure equipment safety.
