For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Combination Figure 1 and Figure 2 The smoke generating device according to the embodiment of the utility model is described.

[0024] In the first aspect, an embodiment of the utility model provides a smoke generating device, including an Internet of Things module 3 and a plurality of smoke generators 1, each smoke generator 1 includes a host 11, the host 11 includes a serial port 12, the serial ports 12 of the plurality of smoke generators 1 are connected in series via a serial bus 2, and are connected to the Internet of Things module 3 via the serial bus 2.

[0025] In this embodiment, each smoke generator 1 may include a host 11, and each host 11 may include one or more serial ports 12. By setting the serial ports 12, the communication efficiency between the multiple smoke generators 1 can be improved, and the serial ports 12 of all smoke generator hosts 11 can be connected in series through the serial bus 2, and the serial bus 2 is connected to the Internet of Things module 3 to form a complete system. As an example, the plurality of smoke generators 1 may include but are not limited to a first smoke generator and a second smoke generator, wherein the first smoke generator may include a first host, the second smoke generator may include a second host, the first host may include a first serial port and a second serial port, and the second host may include a third serial port and a fourth serial port. Specifically, the second serial port can be connected to the third serial port through the serial bus 2, and the fourth serial port can be connected to the Internet of Things module 3 through the serial bus 2 to form a complete system to achieve unified management of all smoke generators 1. Furthermore, the user can connect to the Internet of Things module 3 through a mobile terminal (for example, a smart phone and a tablet computer) to uniformly manage and control all smoke generators 1, avoiding the need to manually turn on each smoke generator 1, resulting in inconsistent smoke concentrations of each smoke generator 1, thereby improving the intelligence level and operating efficiency of the smoke generating device.

[0026] Furthermore, the smoke generator 1 may also include a smoke gun 13 and a delivery component 14, wherein each smoke generator includes a smoke gun 13. Specifically, one end of the delivery component 14 may be connected to a preset port of the host 11, and the other end of the delivery component 14 may be connected to the smoke gun 13, so that the smoke gun 13 generates a smoke flow that flows through the object to be tested. Through the coordinated work of the host 11, the delivery component 14 and the smoke gun 13, the smoke generating device 1 can generate a stable and controllable smoke flow, providing an efficient and reliable solution for various test scenarios.

[0027] Further, the delivery assembly 14 may include a smoke gun cable and an oil pipe bundle, wherein the smoke gun cable is the part of the delivery assembly 14 responsible for transmitting electrical signals and control signals, one end of which is connected to the control module in the host 11 to ensure that the host 11 can accurately control the working state of the smoke gun 13, and the other end is connected to the electrical interface on the smoke gun 13 to achieve real-time communication between the host 11 and the smoke gun 13. The oil pipe bundle is the part of the delivery assembly 14 responsible for transmitting the liquid smoke medium. Similarly, one end of it is connected to the pump or liquid storage in the host 11 to ensure that the liquid smoke medium can be stably and continuously delivered to the smoke gun 13. The other end is connected to the spray device on the smoke gun 13 to atomize the liquid medium into smoke and release it into the air. In actual application, the host 11 is closely connected to the smoke gun 13 through the smoke gun cable and the oil pipe bundle, which not only ensures the stability and reliability of the smoke generation process, but also makes the smoke generator 1 easier to operate and maintain, improves the performance of the smoke generator 1, and provides users with a more convenient use experience.

[0028] It should be noted that, in this embodiment, each smoke generator 1 may also include multiple smoke guns 13. When the smoke generator 1 includes two or more smoke guns 13, in order to ensure that each smoke gun 13 can work stably and evenly, the other end of the conveying component 14 can be connected to the multiple smoke guns 13 respectively, so as to ensure that the instructions issued from the host 1 can simultaneously control the working state of the multiple smoke guns 13, and ensure that they can synchronously generate smoke flow. As an example, when there are two or more smoke guns 13, the conveying component 14 may include multiple smoke gun cables and oil pipe bundles corresponding to the number of smoke guns 13, so as to ensure that each smoke gun 13 can obtain an appropriate amount of smoke, and the flow rate and speed of the smoke flow are consistent. In this way, whether a single smoke gun 13 or multiple smoke guns work at the same time, the stability and accuracy of the test environment can be guaranteed.

[0029] Further, the smoke generating device may also include a smoke generator cabinet 4, and the smoke generator cabinet 4 may include several layers of fixed platforms. By arranging multiple layers of fixed platforms in the smoke generator cabinet 4, space can be effectively utilized and power supply can be conveniently and uniformly performed. The host 11 of several smoke generators 1 can be fixed on the fixed platform through the first fixing component, which further saves space and resources. As an example, the several layers of fixed platforms may include but are not limited to a first layer of fixed platform and a second layer of fixed platform. The first host can be fixedly installed on the first layer of fixed platform through the first fixing component, and the second host can be fixed on the second layer of fixed platform, or the second host can be fixed on the first layer of fixed platform. When the second host is fixed on the first layer of fixed platform through the first fixing component, it is necessary to ensure that a certain distance is maintained from the first host to ensure heat dissipation and convenience of disassembly. Among them, the first fixing component may include but is not limited to screws, buckles and clamps, which can be customized according to the actual size and shape of the host 11 and the fixed platform. For example, a combination of screws and nuts can be used to pre-drill holes on the fixed platform and the host 11, and then the screws are passed through the holes and the nuts are tightened, so that the host 11 is fixed on the fixed platform. By arranging the main unit 11 of each smoke generator 1 on a fixed platform, it is ensured that the performance of the main unit 11 of the smoke generator 1 will not be affected by shaking or displacement during operation.

[0030] Furthermore, the smoke generating device may also include a support member, and by installing the smoke guns 13 of several smoke generators 1 on the support member, the smoke gun 13 of each smoke generator 1 can be effectively supported and fixed, so that it remains stable during use, avoiding affecting the accuracy and reliability of the test. Specifically, the support member may include a smoke array bracket 5 and a base 6, and the smoke array bracket 5 may be further arranged on the base 6, and the smoke gun 13 of each smoke generator 1 may be installed on the smoke array bracket 5. For example, the smoke gun 13 of each smoke generator 1 may be installed on the smoke array bracket 5 in a longitudinal arrangement in sequence through the second fixing component, so that the smoke guns 13 of the multiple smoke generators 1 installed generate multiple smoke streams flowing through the object to be tested, avoiding the situation where the smoke gun 13 shakes or deflects during use, and also ensuring that the multiple smoke streams can accurately and evenly flow through the object to be tested. It should be noted that the second fixing component may include screws, buckles and clamps, and the specific fixing method is not limited by the utility model.

[0031] Furthermore, the smoke generator 1 further includes an oil bottle 15, which is connected to the host 11 as the source of smoke generation, and together constitutes the core part of the smoke generator 1. The oil bottle 15 can be made of high-quality materials, such as glass, plastic or stainless steel, etc., and has excellent sealing and corrosion resistance, and can ensure the continuity and stability of smoke generation. By introducing the oil bottle 15, each smoke generator 1 can continuously and stably generate smoke, providing a reliable smoke source for various test scenarios.

[0032] Furthermore, the host 11 also includes a power switch 16, a smoke switch 17 and a concentration adjustment knob 18. By arranging the power switch 16, the smoke switch 17 and the concentration adjustment knob 18 on the host 11, it is avoided that when the Internet of Things module 3 is damaged, the smoke concentration of each smoke generator 1 cannot be turned off or adjusted, which greatly improves the user experience.

[0033] Furthermore, the smoke generating device further includes a circuit control component, which is respectively connected to the host 11 of the plurality of smoke generators 1 and the Internet of Things module 3, wherein the circuit control component may include a circuit switch. As an example, the circuit control component may be connected to the host 11 of the plurality of smoke generators through a first line, and connected to the Internet of Things module 3 through a second line, so as to provide the power required for the host 11 of the plurality of smoke generators 1 and the Internet of Things module 3 to work, thereby ensuring the stability of power supply and the high efficiency of data transmission, and providing users with a more convenient and efficient use experience.

[0034] It should be understood that the smoke generating device provided by the present invention is only an example, and the present invention is not specifically limited thereto.

[0035] In the second aspect, the embodiment of the utility model provides a working principle of a smoke generating device:

[0036] As an example, the host computers 11 of several smoke generators 1 can be installed on the smoke generator cabinet 4, and the serial ports 12 of all the smoke generators 1 can be connected using the serial bus 2, and then the serial bus 2 can be connected to the Internet of Things module 3 to form a complete system. Further, the mobile terminal can be connected to the Internet of Things module 3. When it is necessary to control the opening or closing of multiple smoke generators 1 or adjust the smoke density of multiple smoke generators 1, the mobile terminal can send a command to the Internet of Things module 3, and the Internet of Things module 3 forwards the received command information to the serial bus 2, so that the serial bus 2 can find the corresponding smoke generator 1 according to the command information number, thereby controlling the opening or closing of the smoke generator 1, or adjusting the smoke density of the smoke generator 1.

[0037] For example, a mobile terminal (e.g., a tablet computer) can be used to search and connect to the wireless hotspot emitted by the Internet of Things module 3. After the hotspot is connected, the "Wind Tunnel Smoke Generator 1 Control" software is opened on the mobile terminal, and the software automatically initiates a TCP / IP connection request and connects to the Internet of Things module 3. In the software operation interface, the "All" button can be selected to select all smoke generators 1, or the button of the smoke generator 1 that does not need to be controlled can be deselected, and the smoke density of each smoke generator 1 can be adjusted through the smoke density adjustment method displayed on the operation interface. For example, when the initial position of the slider is 0%, the smoke generator 1 is in a closed state. When sliding to the right, the slider value changes from 0% to 100%, and the number and smoke density data of the smoke generator 1 selected on the operation interface are sent to the Internet of Things module 3 through the TCP / IP protocol. The Internet of Things module 3 forwards the data to the serial bus 2. The serial bus 2 addresses according to the number of the smoke generator 1, finds the smoke generator 1 with the specified number, and sets the corresponding concentration value. Finally, the concentration adjustment and switch functions of all smoke generators 1 are synchronously controlled by the mobile terminal, and the synchronous adjustment and control of multiple smoke generators 1 and the simultaneous opening and closing of multiple smoke generators 1 are realized, thereby improving the regulation efficiency of multiple smoke generators 1.
