[0083] Specifically, such as Figure 4 and Figure 9 As shown, the fire-fighting robot includes a speaker 9, and a gradient hole 14 is provided on the side circumferential plate 11 of the shell 1. The positions of the speaker 9 and the gradient hole 14 match to facilitate the propagation of sound. In this embodiment, the gradient hole 14 includes a plurality of circular holes, and the plurality of circular holes are arranged in multiple layers. The diameters of the circular holes in the same layer are the same, and the centers of the circular holes in the same layer are located on the same circumference. The diameters of the circular holes in different layers are different. The centers of the circular holes in multiple layers are concentrically arranged on the circumference, and the diameters of the circular holes in two adjacent layers decrease as the diameter of the circumference where the centers of the circular holes are located increases. The setting of the gradient hole 14 not only creates a dynamic effect from the inside out visually, but also helps to propagate sound and dissipate heat. The gradient hole 14 helps to propagate the sound of the speaker 9, making the alarm sound or voice command issued by the fire-fighting robot clearer, ensuring that the alarm information can be quickly and accurately conveyed to the user in an emergency. At the same time, the gradient hole 14 also takes into account the need for heat dissipation. A larger central aperture helps to provide a larger heat dissipation area, and the decrease in the diameter of the two adjacent layers of circular holes as the diameter of the circle where the center of the circular hole is located increases helps to form a chimney effect to guide heat to dissipate outward, thereby maintaining a suitable temperature of the internal structure of the fire-fighting robot shell 1 and avoiding performance degradation or damage to the fire-fighting robot due to overheating inside the shell 1.

[0084] The gradual hole 14 also enhances the overall rigidity and stability of the housing 1, making the firefighting robot more stable and reliable when moving or performing tasks. In addition, the gradual hole 14 also helps to reduce the weight of the robot and improve its mobility and flexibility.

[0085] Further, if Figure 1 、 Figure 2 and Figure 3 As shown, the housing 1 is designed as a rounded rectangular structure. This not only reduces the risk of damage to furniture or family members during the firefighting robot's rapid movements, but also gives the firefighting robot a gentle and friendly appearance, making its appearance more concise and streamlined, enhancing the aesthetics of the home environment. Furthermore, the housing 1 utilizes an advanced surface treatment process, making it not only pleasant to the touch but also easy to clean and maintain.

[0086] Further, if Figure 1 and Figure 6 As shown, the fire fighting robot also includes a battery 11, a charging base 6 and a charging coil 111. Figure 1 As shown, the charging station is connected to the power supply. Figure 6 As shown, the battery 11 and the charging coil 111 are arranged in the housing 1, the battery 11 is arranged on the bottom plate 13, the charging coil 111 is arranged on the side plate 11, the charging coil 111 is a wireless charging coil, and the charging base 6 is a wireless charging base. When charging, the charging coil 111 and the charging base 6 are wirelessly connected. The battery 11 can meet the endurance requirements of the fire-fighting robot. When the power of the battery 11 is lower than the preset power, the automatic charging function will be triggered. The preset power is 20% of the total storage capacity. The fire-fighting robot is also provided with a charging indicator light. The charging indicator light is red when charging is in progress and blue when charging is complete. In order to avoid fires that cannot be discovered in time during charging, the fire-fighting robot is also provided with a backup power supply, which is arranged on the bottom plate 13.

[0087] Further, if Figure 1 and Figure 3As shown, the fire-fighting robot also includes an infrared transmitting device, an infrared receiving device and a camera 5, which together constitute a radar system. The infrared transmitting device, the infrared receiving device and the camera 5 are arranged on the upper part of the side peripheral plate 11. The infrared transmitting device transmits radio waves at regular intervals. When encountering an obstacle, the radio waves will be reflected back and captured by the infrared receiver. The fire-fighting robot also includes a control module. By measuring the time difference between the transmitted radio waves and the received radio waves, the control module can calculate the distance and moving speed of the obstacle. The fire-fighting robot can also process and analyze the received radio wave signals to determine the precise position, size and moving state of the obstacle. The control module can process this data in real time and calculate the optimal obstacle avoidance path through the obstacle avoidance algorithm to ensure that the fire-fighting robot safely bypasses or stops to avoid collision.

[0088] The roller drive motor 71 is electrically connected or wirelessly connected to the control module. According to the instructions of the control module, the roller drive motor 71 drives the roller 7 to move forward, backward, sideways or turn.

[0089] Furthermore, the upper cover structure 2, the fire detection assembly, the adjustment platform, the switch structure and the fourth drive motor 101 are respectively electrically connected or wirelessly connected to the control module.

[0090] Furthermore, the firefighting robot also includes a WiFi module, an infrared module, and a Bluetooth module, which are electrically connected or wirelessly connected to the control module. The WiFi module, infrared module, and Bluetooth module enable wireless communication between the control module and smart home devices, such as lights, televisions, refrigerators, washing machines, electric curtains, indoor ventilation systems, and indoor power systems. The fire detection component is electrically connected or wirelessly connected to the control module. When the control module determines that a fire has occurred based on the fire detection component, the control module determines the fire level based on the information fed back by the fire detection component and executes emergency measures based on the fire level. Emergency measures include but are not limited to shutting down the indoor power system and turning on the indoor ventilation system. Shutting down the indoor power system can prevent the spread of electrical fires, and turning on the indoor ventilation system can dilute the smoke and reduce the temperature, creating a safer evacuation environment at the fire scene and minimizing the losses caused by the fire. Among them, the severity and urgency of the fire can be judged based on the fire level.

[0091] Furthermore, the control module is also used to transmit the obtained fire severity level to the user. Specifically, when the firefighting robot detects a fire, it automatically triggers an alarm and rapidly transmits the identified fire status information to the user and relevant emergency departments via various communication methods. This setting is the firefighting robot's remote notification function, a key component in fire prevention and response.

[0092] Specifically, when a fire occurs, the firefighting robot can quickly detect abnormal temperature increases or changes in smoke concentration through its fire detection component. The control module then identifies the fire, automatically triggering an alarm, and assessing its severity. Once a fire is confirmed, the firefighting robot immediately activates its alarm system, emitting a loud siren through its speaker 9. Simultaneously, it activates its remote notification function, sending a fire notification to connected smart devices and relevant emergency departments via the home wireless network. If the home wireless network fails, the firefighting robot's backup communication system immediately activates, sending text messages or making phone calls via its built-in SIM card, ensuring that information can be conveyed through traditional communication methods.

[0093] The firefighting robot's remote notification function takes into account various scenarios, such as when family members are asleep late at night, away at work, or traveling. Regardless of the scenario, the firefighting robot ensures that family members receive timely fire notifications via the home wireless network or backup communication system. Timely fire notification is crucial for early detection and rapid response, significantly reducing casualties and property damage caused by fires.

[0094] As a specific embodiment, the control module is used to receive temperature information and smoke concentration information fed back by the fire detection component in real time. When the control module determines that a fire has occurred based on the feedback information from the fire detection component, the control module is used to sound an alarm through the speaker 9 and send the fire level information obtained through analysis to the client of the family members; at the same time, the control module is used to plan the travel path based on the feedback information from the camera 5, the infrared transmitting device, and the infrared receiving device, and control the roller drive motor 71 to drive the roller 7 to move to the fire point according to the planned travel path; the control module is also used to control the upper cover structure 2 to open the opening of the accommodating cavity, and control the operation of the adjustment platform to send the fire extinguishing equipment 8 upward out of the accommodating cavity; the control module is also used to control the fourth drive motor 101 to adjust the pitch angle of the nozzle 81 based on the feedback information from the camera 5, so that the nozzle 81 is aimed at the root of the fire point; the control module is used to control the switch structure to open the valve switch 82 of the fire extinguishing equipment 8 to extinguish the fire.

[0095] Furthermore, the control module is also used to detect the amount of power in the battery 11. When it is detected that the amount of power in the battery 11 is less than a preset amount of power, the control module plans a travel path based on the feedback information from the camera 5, the infrared transmitting device, and the infrared receiving device, and controls the roller drive motor 71 to drive the roller 7 to move to the charging base 6 according to the planned travel path to wirelessly charge the battery 11; the control module is also used to cut off the connection between the charging station and the wireless charging coil when it is detected that the battery 11 is full of power.

[0096] Furthermore, map information is set in the control module, and the control module is used to plan the travel route based on the map information, the feedback information of the camera 5, the infrared transmitting device, and the infrared receiving device.

[0097] Furthermore, a patrol path is preset in the control module, and the control module is used to control the fire-fighting robot to patrol along the patrol path at regular intervals or randomly, so as to better grasp the home environment and improve the timeliness of fire detection.

[0098] Furthermore, the seamless linkage between the fire-fighting robot and other smart home devices makes the fire-fighting robot the smart center of the home, which not only protects the safety of the family but also greatly improves the convenience of living.

[0099] For example, the control module receives user commands, identifies and analyzes them to determine user intent, and then controls smart home devices based on that intent. Users can use the fire robot to control various smart home devices, such as lights, air conditioners, and televisions, through simple voice commands. Whether adjusting the temperature while busy in the kitchen or changing the lighting while relaxing in the living room, the fire robot accurately understands the user's commands and responds quickly. Voice control not only frees users' hands but also makes smart home devices more user-friendly and easy to operate.

[0100] Furthermore, the control module is also used to obtain historical command data, analyze and summarize it using a built-in neural network learning model to generate a recommended list, and then send this recommended list to the user. The neural network learning model is trained using a large number of control commands from smart home devices. For example, the control module generates a recommended list based on the user's historical command data, which can be used to predict user needs. When the control module detects that it is the user's daily rest time, it sends inquiries such as "Dim the lights" or "Adjust the room temperature" to the user, and adjusts the lighting brightness and air conditioning temperature based on the user's responses. It can even send an audio query such as "Play..." based on the user's habits to create a comfortable sleeping environment. In the morning, based on the user's wake-up time, the control module can control the electric curtains to open, the TV to turn on, and play the user's favorite videos in advance.

[0101] The control module also communicates with the user's mobile devices, such as smartphones and tablets. It can remotely control the power on and off of smart home devices based on user commands. For example, a user could remotely control the air conditioner on their way home using the client and the fire robot, or check the safety of their home using the client and the fire robot while out and about.

[0102] The fire-fighting robot of the present application is not only suitable for household fire extinguishers but also for slightly larger commercial fire extinguishers. Therefore, the fire-fighting robot of the present application is not only suitable for ordinary households but can also meet the needs of some special occasions, such as small commercial places or office environments.
