The housing 100, for example, is provided with an air outlet 110, and the air outlet 110 is, for example, arranged near the upper end of the housing 100, and the air outlet 110 is, for example, arranged toward the fire source of the external fire source equipment, and when the wind is discharged from the air outlet 110, the fire source of the external fire source equipment is extinguished. The air duct 130, for example, is arranged in the housing 100, and the air duct 130 is connected to the air outlet 110. The blowing device 200, for example, is arranged inside the housing 100, and the blowing device 200 is used to blow air to the air duct 130, and the blowing device 200 can be, for example, a centrifugal turbine blowing device, a diagonal flow blowing device, or an axial flow blowing device or other blowing devices of the prior art, and the blowing device 200 can also be, for example, an electric air pump, which conveys gas and is discharged from the air outlet 110 to extinguish the fire source, which is not specifically limited here. The connection structure 300 is, for example, disposed on the housing 100. The housing 100 is connected to the external fire source device through the connection structure 300 so that the air outlet 110 faces the fire source of the external fire source device. The wind generated by the blowing device 200 when working is guided out from the air outlet 110 through the air duct 130 to extinguish the fire source of the external fire source device. The connection structure 300 includes, for example, one or more of an adhesive structure, a magnetic structure, and a wall-mounted structure.

Alternatively, the connection structure 300 includes, for example, screws or bolts, and the housing 100 is fixed to the outer wall of the external fire source device through screws or bolts. Alternatively, the connection structure 300 may include a combination of multiple structures among an adhesive structure, a magnetic structure, and a wall-mounted structure. The specific selection can be made according to the actual structure of the product and user needs. Of course, the above is only an example, and the present embodiment is not limited thereto.

[0030] Specifically, the housing 100 is provided with an air inlet 120, for example, and the air inlet 120 is connected to the air duct 130. Figure 1 The air inlet 120 is, for example, disposed on the side wall of the housing 100 , and the air inlet 120 and the air outlet 110 are located on different sides of the housing 100 . The specific positions of the air inlet 120 and the air outlet 110 are not limited here. Figure 3The blowing device 200 has an air inlet 220 and an air outlet 210 respectively connected to the air duct 130, the air outlet 210 is connected to the air outlet 110, and the air inlet 220 is arranged corresponding to the air inlet 120 to ensure that the air flow is smoothly introduced into the blowing device 200 from the air inlet 120. The blowing device 200 is used to guide the air flow generated by the blowing device 200 to flow out of the air outlet 110 through the air outlet 210. For example, the housing 100 is provided with an air inlet 120, and the air inlet 120 is connected to the air duct 130. When the blowing device 200 is started, the external gas is sucked into the housing 100 through the air inlet 120, passes through the air inlet 220 and the air outlet 210 of the blowing device 200 in sequence, and is then guided out from the air outlet 110.

[0031] The embodiment of the utility model sets a connecting structure 300 on the shell 100, so that the shell 100 is connected to the outer wall of the external fire source equipment, and the shell 100 is provided with an air outlet 110, and the air outlet 110 is set to face the fire source of the external fire source equipment. When the blowing device 200 inside the shell 100 is working, the wind generated by the blowing device passes through the inside of the shell 100 and is discharged from the air outlet 110 to extinguish the fire source of the external fire source equipment, so as to solve the problem that the user is sometimes inconvenient to extinguish the fire source with his mouth or tools such as a fire extinguisher, so that the user can extinguish the fire source without directly approaching the fire source, thereby reducing the risk of causing fire or burns, and the extinguishing device 10 provided by the embodiment of the utility model can be connected to the outer wall of the external fire source equipment for a long time, does not require frequent operation, and provides continuous convenience for users.

[0032] In some embodiments, reference Figure 4 The housing 100 is provided with a hook portion 310, for example, and the connecting structure 300 is, for example, a hook portion 310, and the hook portion 310 is used to contact an external fire source device. For example, the upper end of the housing 100 is, for example, provided with Figure 4 The "barb" shape shown is used to form the hook portion 310, and the "barb" shape is conducive to firmly hanging or grabbing the edge or protrusion of the external fire source device to connect the housing 100 with the external fire source device. It should be noted that the bending degree and size of the hook portion 310 can be designed according to actual needs, so that it can better adapt to external fire source devices of different shapes and sizes.

[0033] Refer to Figure 4 Specifically, the housing 100 includes an inner shell surface 103 and an outer shell surface 104 that are arranged opposite to each other. The inner shell surface 103 is arranged close to the external fire source equipment. For example, the inner shell surface 103 is Figure 4On the left side of the middle shell 100, an air duct 130 is formed between the inner shell surface 103 and the outer shell surface 104. The inner shell surface 103 includes a bending surface 1031. The bending surface 1031 is arranged close to the top of the shell 100. The bending surface 1031 forms a hook portion 310. The hook portion 310 and the air duct 130 share the same structure for discharging air from the air outlet 110, which reduces additional components and enhances the stability of the overall structure.

[0034] Specifically, the upper end of the outer shell surface 104 is, for example, a bent surface, and a wind outlet surface 1041 is provided on the side of the outer shell surface 104 close to the external fire source device. The wind outlet surface 1041 is, for example, Figure 4 As shown in the leftmost vertical surface, the air outlet 110 is located on the air outlet surface 1041 .

[0035] Reference Figure 2 and Figure 6 , the extinguishing device 10 further includes a controller 400. Specifically, the controller 400 is disposed in the housing 100, and the controller 400 is electrically connected to the blowing device 200. The controller 400 is an integrated circuit board, which includes electronic devices with data processing functions such as CPU, MCU, DSP, etc., for receiving external instructions (such as user operation commands or signals from other electronic devices) and processing these instructions, and controlling the blowing device 200 to perform corresponding actions, such as opening and closing.

[0036] Reference Figure 6 The extinguishing device 10 further includes a control switch 500, which is set at Figure 1 On the shell surface 104 shown. The control switch 500 is, for example, electrically connected to the controller 400. The control switch 500 is used to control the opening and closing of the blowing device 200. The control switch 500 can be a physical switch made of plastic, metal or other durable materials, or a switch that is sensitive to touch or sound, and the switch type of the control switch 500 is not limited here. The control switch 500 is used to send specific control signals to the controller 400, and the controller 400 receives the specific control signals and processes these signals, and controls the blowing device 200 to perform corresponding actions, such as opening and closing. Among them, the specific control signal is, for example, a signal such as opening and closing, and the specific setting of the specific control signal can be designed according to user needs and is not limited here.

[0037] Reference Figure 6 The extinguishing device 10 further includes a timing module 600. The blowing device 200 includes an open state, for example. The timing module 600 is electrically connected to the control switch 500 and the controller 400, and the timing module 600 is used to time the open state of the blowing device 200.

[0038] Among them, the timing module 600 includes, for example, a timer circuit, and the user can set the timing duration of the start-up of the blowing device 200 through a button (the button can be set separately on the extinguishing device 10 or integrated on the control switch 500) or a touch screen, etc. The timing duration can be set according to user needs and is not limited here. For example, when the user sets the time and activates the timing module 600 through the control switch 500, the timing module 600 starts the countdown. After the countdown ends, the timing module 600 sends a signal to the controller 400 to control the start-up of the blowing device 200. In other embodiments, the timing module 600 can also be used to time the closing of the blowing device 200, which is not limited here.

[0039] By setting the timing module 600, this embodiment not only improves the convenience and safety of the operation of the extinguishing device 10, but also increases the flexibility to meet various usage requirements.

[0040] Reference Figure 2 The extinguishing device 10 further includes, for example, an air regulating mechanism 700, which can adjust the angle at which the air blown by the blowing device 200 to the air duct 130 is directed out of the air outlet 110. In some embodiments, the air regulating mechanism 700 is, for example, manually controlled, such as by manually changing the position of the air regulating mechanism 700 through a knob, a sliding rod, etc., so as to adjust the wind direction at the air outlet 110. In some embodiments, the air regulating mechanism 700 is, for example, controlled by an electrical signal, such as by sending a control signal through a microcontroller to change the position of the air regulating mechanism 700, so as to adjust the wind direction at the air outlet 110. The method of controlling the air regulating mechanism 700 is not limited here.

[0041] Reference Figure 6 The air regulating mechanism 700 is, for example, electrically connected to the controller 400, and the air regulating mechanism 700 can adjust the angle at which the wind blown by the blowing device 200 to the air duct 130 is directed out of the air outlet 110. By arranging the air regulating mechanism at the air outlet 110, the air regulating mechanism 700 can adjust the angle of the wind blown by the blowing device 200 to the air duct 130 and out of the air outlet 110 relative to the fire source of the external fire source device. The air regulating mechanism 700 allows the user to accurately control the wind direction as needed, ensuring that the wind can be blown directly to the fire source, thereby more effectively extinguishing the flame. Specifically, a touch screen can be provided on the extinguishing device 10, and the user can send control instructions to the air regulating mechanism 700 through the touch screen to adjust the angle at which the wind blown by the blowing device 200 to the air duct 130 is discharged from the air outlet 110 to ensure that the wind can be blown directly to the fire source. The user can also control the air regulating mechanism 700 through wireless communication means, such as through mobile terminals such as mobile phones and tablets. The user can also control the air regulating mechanism 700 through a wireless remote control matched with the extinguishing device 10, and there is no specific limitation here.

[0042] Reference Figure 2, the air regulating mechanism 700 includes, for example, a driving member 710 and an air regulating member 720. The driving member 710 is, for example, disposed in the housing 100, and the driving member 710 is electrically connected to the controller 400. The driving member 710 is, for example, a device that can provide mechanical power, such as an electric motor or a pneumatic motor, and the driving member 710 is used to drive the air regulating member 720 to rotate or move relative to the air outlet 110. The air regulating member 720 is, for example, an air regulating baffle, and the air regulating member 720 is, for example, directly connected to one end of the driving member 710 or connected to the driving member 710 through a transmission structure such as a gear, a belt, and a worm gear, to ensure that the driving member 710 can drive the air regulating member 720 to rotate. The connection method and relative position of the air regulating member 720 and the driving member 710 are not limited here. Refer to Figure 5 The air regulating member 720 is, for example, disposed near the air outlet 110 and on the inner side of the shell 100. In other embodiments, the air regulating member 720 may also be disposed on the outer side of the shell 100. It is only necessary to ensure that the rotation of the air regulating member 720 can change the angle of the wind blown out of the air outlet 110 relative to the external fire source equipment. No specific limitation is made here.

[0043] The driving member 710 drives the air regulating member 720 to rotate relative to the air outlet 110 to change the angle of the air regulating member 720 relative to the air outlet 110, thereby changing the angle at which the wind blown by the blowing device 200 to the air duct 130 is directed out of the air outlet 110. For example, the controller 400 sends a control signal to the air regulating mechanism 700, and the control signal indicates the required wind direction adjustment. According to the control signal, the driving member 710 starts to work, and the driving member 710, for example, starts to rotate to drive the air regulating member 720 to rotate. The change in the position or angle of the air regulating member 720 relative to the air outlet 110 causes the airflow direction of the blowing device 200 blowing out of the air outlet 110 to change, thereby changing the angle at which the wind is directed out of the air outlet 110, so as to ensure that the fire source of the external fire source equipment is extinguished.

[0044] Reference Figure 6 , the extinguishing device 10, for example, further includes a flameout detection module 800. The flameout detection module 800 is, for example, electrically connected to the controller 400, and the flameout detection module 800 is used to detect the state of the fire source of the external fire source device, and the state of the fire source of the external fire source device includes an extinguished state and an unextinguished state. The flameout detection module 800 converts the detected state of the fire source (for example, the state of the fire source being extinguished or the state of the fire source being unextinguished) into an electrical signal, and sends it to the controller 400. For example, the flameout detection module 800 detects the state of the fire source as, for example, an extinguished state, and converts it into an electrical signal and sends it to the controller 400, and the controller 400 controls the blowing device 200 to turn on, and the wind generated by the blowing device 200 is guided out from the air outlet 110 through the air duct 130 to extinguish the fire source of the external fire source device.

[0045] In this embodiment, a flameout detection module 800 is provided. After the blowing device 200 stops working, the controller 400 can, for example, control the flameout detection module 800 to detect whether the external fire source equipment is successfully extinguished, thereby ensuring that the extinguishing device 10 can respond in time when the fire source is ignited or extinguished (for example, controlling the opening of the blowing device 200), which helps prevent fire accidents and improve safety.

[0046] Specifically, refer to Figure 7 The flameout detection module 800 includes, for example, a photo sensor 810 and a light guide structure 820. The photo sensor 810 is, for example, electrically connected to the controller 400. The light guide structure 820 is, for example, disposed on the housing 100, partially exposed from the housing 100, and electrically connected to the photo sensor 810.

[0047] The photosensitive element 810 is, for example, a photoresistor, a photodiode, a phototransistor, etc., which can detect light signals and convert them into electrical signals. The light-guiding structure 820 is, for example, a light-guiding optical fiber, which is used to guide the light signals to the photosensitive element 810. The light-guiding structure 820 transmits the light signals to the photosensitive element 810, and the photosensitive element 810 converts the light signals into electrical signals, which are then transmitted to the controller 400.

[0048] In this embodiment, when the fire source of the external fire source equipment is in a burning state (i.e., not extinguished), the light emitted by the flame (such as visible light or infrared light) will be sensed by the light-guiding structure 820, and the light-guiding structure 820 will transmit the sensed light signal to the photo sensor 810. The photo sensor 810 will convert the received light signal into an electrical signal, which will then be sent to the controller 400. The controller 400 will determine the state of the fire source (extinguished or not extinguished) based on the electrical signal, and then control whether the blowing device 200 is turned on.

[0049] In this embodiment, when the external fire source device needs to be extinguished, the extinguishing device 10 is mounted on the external fire source device through the connecting structure 300, and the air outlet 110 is aimed at the external fire source device. When the extinguishing device 10 is in the off state, the user can, for example, turn on the control switch 500 by long pressing, and the controller 400 responds to the control switch 500, thereby controlling the blowing device 200 to turn on to extinguish the fire source of the external fire source device; the user can also, for example, short press the control switch 500 to perform timing through the timing module 600, and the timing operation For example, it may include multi-gear timing, and different gears may correspond to different durations of touching the control switch 500, or may correspond to different short press times. By timing the timing module 600, the controller 400 controls the blowing device 200 to work at the end of the timing. The wind generated by the blowing device 200 when working is guided out from the air outlet 110 through the air duct 130 to extinguish the fire source of the external fire source equipment, and the controller 400 may, for example, control the blowing device 200 to continue working for a certain period of time to further improve the success rate of extinguishing the external fire source equipment. After the blowing device 200 stops working, the controller 400 may, for example, control the extinguishing detection module 800 to detect whether the external fire source equipment is extinguished. When it is detected that the external fire source equipment is not extinguished, the controller 400 controls the blowing device 200 to extinguish the external fire source equipment. When it is detected that the external fire source equipment is extinguished, the extinguishing device 10 enters the shutdown state.

[0050] In a specific implementation of the present embodiment, the control switch 500, for example, includes a key circuit, generates different key operation signals according to the pressing operation duration of different key operations, and sends the key operation signals to the controller 400. For example, the user can realize the shutdown operation of the extinguishing device 10 by pressing the control switch 500 for 2 to 3 seconds. The user can realize the power-on operation of the extinguishing device 10 by pressing the control switch 500 for 0.1 seconds. The user can, for example, enter the blowing mode by long pressing the control switch 500, turn on the blowing device 200 to blow, and release the control switch 500 to stop the blowing device 200. The user can also, for example, switch the gear of the blowing device 200 by lightly pressing the control switch 500, and change the wind speed of the blowing device 200 by controlling the power size, which is not limited here. The user can also switch the timing time by, for example, lightly pressing the control switch 500, and automatically enter the shutdown state after releasing the control switch 500. The timing duration can be, for example, 0.5h, 1h, or 2h, etc., and the specific duration is not limited here. After the timing duration ends, the timing module 600 will send a signal to the controller 400 to control the blowing device 200 to start to extinguish the external fire source equipment. During the extinguishing process or after the extinguishing is completed, the extinguishing detection module 800 determines whether the extinguishing is successful. If the extinguishing is successful, the extinguishing device 10 automatically enters the shutdown state. If the extinguishing is not successful, the blowing device 200 and the air regulating mechanism 700 are controlled to perform the extinguishing operation again until the extinguishing is successful. Of course, the above is only an example, and the present embodiment is not limited thereto.

[0051] The extinguishing device 10 may also include an indicator light, which is, for example, disposed on the housing 100 and electrically connected to the controller 400. The indicator light is used to indicate a timing state, a charge and discharge state, or a power state under the control of the controller 400. The number and purpose of the indicator light may be set, for example, as needed, and is not specifically limited here.

[0052] It should be noted that, refer to Figure 1 and Figure 2 The extinguishing device 10 may further include necessary components such as a power module 900 and a power connection interface 910, which are not described one by one in this embodiment.
