Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined. It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" in the description of this application should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this article can be understood according to specific circumstances.

[0053] In this application, the word "exemplary" is used to mean "used as an example, illustration, or description." Any embodiment described in this application as "exemplary" is not necessarily to be construed as being preferred or advantageous over other embodiments. The following description is given to enable any technician in the field to implement and use the present application. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, well-known structures and processes will not be elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0054] Containers, energy storage cabinets and other cabinets can be used to store equipment. Energy storage cabinets can be used to store batteries. Containers can be used to store a variety of equipment. During the use of the cabinet, when some equipment in the cabinet overheats, it may cause a fire.

[0055] During the life cycle of the cabinet, smoke detectors can be used to monitor the cabinet for fire. For example, the smoke detectors of fire monitoring equipment use smoke particles to diffuse light, so that the impedance change of the photoresistor generates photocurrent, and the detector sends out an alarm signal. However, when there are many water vapor particles in the air, the water vapor particles enter the optical maze, causing the light intensity received by the receiver to increase, which is prone to false alarms and affects the normal operation of the smoke detector.

[0056] In order to solve the problem that the detector is prone to false alarms, the present application proposes a smoke detection device, including a mounting shell, a dehumidification component and a smoke sensing component. The mounting shell has an air duct and an air inlet and an air outlet respectively connected to the air duct; the dehumidification component is arranged in the air duct, the air inlet side of the dehumidification component is connected to the air inlet, and the air outlet side of the dehumidification component is connected to the air outlet; the smoke sensing component is arranged in the air duct, the smoke sensing component is arranged on the air outlet side of the dehumidification component, and the smoke sensing component is used to perform smoke detection on the airflow output by the dehumidification component. In the example of the present application, after the gas input into the air duct is dehumidified by the dehumidification component, the water vapor in the airflow is reduced, so that the influence of water vapor on the airflow is reduced when the smoke sensing component detects smoke, thereby reducing the false alarms of the smoke sensing component.

[0057] See also Figure 1 The smoke detection device 20 in the example of the present application can be used in a cabinet 100, which can be an electrical cabinet or other box structure that can be used to store equipment. The smoke detection device 20 can be used to perform smoke detection on the cabinet 100, and thus timely obtain information on whether there is a fire in the cabinet 100.

[0058] See also Figure 2 The present application proposes an example of a smoke detection device 20, including a mounting shell 21, a dehumidification component 22 and a smoke sensing component 25, the mounting shell 21 has an air duct 211 and an air inlet 212 and an air outlet 213 respectively connected to the air duct 211; the dehumidification component 22 is at least partially arranged in the air duct 211, the air inlet side of the dehumidification component 22 is connected to the air inlet 212, and the air outlet side of the dehumidification component 22 is connected to the air outlet 213, the dehumidification component 22 is used to dehumidify the airflow entering the air duct 211; the smoke sensing component 25 is arranged in the air duct 211, the smoke sensing component 25 is arranged on the air outlet side of the dehumidification component 22, and the smoke sensing component 25 is used to detect smoke on the airflow output by the dehumidification component 22.

[0059] The mounting shell 21 is at least partially hollow so that an air duct 211 is formed inside the mounting shell 21. The inner contour of the air duct 211 may be a regular polygon or a cylinder, or an irregular shape. The mounting shell 21 is provided with an air inlet 212 and an air outlet 213. The air inlet 212 is connected to the air duct 211, and air flow can enter the air duct 211 from the air inlet 212. The air outlet 213 is connected to the air duct 211, and the air flow in the air duct 211 can be output to the outside of the mounting shell 21 through the air outlet 213.

[0060] The dehumidification component 22 is at least partially disposed in the air duct 211, which means that the dehumidification component 22 can be partially or entirely located inside the air duct 211. The dehumidification component 22 has an air inlet side and an air outlet side, and the air flow can flow from the air inlet side of the dehumidification component 22 to the air outlet side. The air inlet side of the dehumidification component 22 is connected to the air inlet 212, and the air outlet side of the dehumidification component 22 is connected to the air outlet 213, so that the air flow entering the air duct 211 can be dehumidified by the dehumidification component 22 and then output in the direction of the air outlet 213. The dehumidification component 22 in this example can be used to dehumidify the air flow entering the air duct 211, and the dehumidification can be a dehumidification method such as adsorption, heat exchange, or a combination of multiple dehumidification methods.

[0061] The smoke sensing component 25 is disposed in the mounting shell 21, and is used to detect smoke from the gas in the mounting shell 21. The smoke sensing component 25 is disposed between the air outlet side of the dehumidification component 22 and the air outlet 213. After the airflow passes through the dehumidification component 22 for dehumidification, the smoke sensing component 25 detects smoke from the airflow after the dehumidification treatment. The mounting shell 21 may have a bottom wall 215 and a top wall disposed above the bottom wall 215, wherein the smoke sensing component 25 may be disposed close to the top wall.

[0062] In this example, the airflow is first dehumidified to reduce the water vapor content of the airflow delivered to the smoke sensing component 25, which can effectively reduce the impact of water vapor on the smoke sensing component 25, reduce the complexity of the airflow components, and reduce the problem of false alarms of the smoke sensing component 25 due to water vapor.

[0063] Optionally, the smoke sensing component 25 can be in a normally open state to continuously detect ambient smoke; the dehumidification component 22 can be continuously turned on, on the one hand for circulating and dehumidifying the ambient air, on the other hand to improve the detection accuracy of the smoke sensing component 25; optionally, the dehumidification component 22 can also be turned on intermittently, and when the ambient humidity of the smoke detection device 20 reaches a preset humidity, the dehumidification component 22 is turned on for dehumidification.

[0064] In some examples, the smoke detection device 20 further includes an alarm component 24 , which is electrically connected to the smoke sensing component 25 , and the alarm component 24 is used to generate an alarm according to the smoke signal of the smoke sensing component 25 .

[0065] The alarm component 24 is electrically connected to the smoke sensing component 25, which means that the alarm component 24 can directly or indirectly transmit electrical signals to the smoke sensing component 25. The smoke sensing component 25 can be used to obtain smoke signals, and the alarm component 24 can alarm according to the smoke signals. The alarm component 24 in this example can use at least one of sound, light, and electricity as an alarm method. The alarm component 24 can be set on the mounting shell 21. Optionally, the smoke detection device 20 can be set on equipment such as energy storage cabinets and containers, and the alarm component 24 can be installed on energy storage cabinets or containers; optionally, the alarm component 24 can also be installed on a remote host computer.

[0066] In some examples, the smoke sensing component 25 includes a smoke probe 251 and a detector body 252. The smoke probe 251 is arranged between the air outlet side of the dehumidification component 22 and the air outlet 213, and is used to detect smoke signals; the smoke probe 251 and the alarm component 24 are respectively electrically connected to the detector body 252, and the detector body 252 is used to control the alarm component 24 to alarm according to the smoke signal.

[0067] The smoke probe 251 can be used to detect smoke signals. The smoke probe 251 is electrically connected to the detector body 252 so that the detector body 252 can obtain the smoke signal obtained by the smoke probe 251. In this example, the smoke probe 251 and the detector body 252 can be arranged close to each other, or the smoke probe 251 and the detector body 252 can be arranged at different positions of the mounting shell 21. Optionally, the smoke probe 251 can be arranged at a position close to the top wall of the mounting shell 21.

[0068] The detector body 252 is electrically connected to the alarm component 24 so that signals can be transmitted between the detector body 252 and the alarm component 24. When the detector body 252 obtains a smoke signal that reaches a preset value, the detector body 252 can send an electrical signal to the alarm component 24 so that the alarm component 24 sounds an alarm. In this example, the detector body 252 and the alarm component 24 can be connected by wire or wirelessly.

[0069] In some examples, the dehumidification component 22 includes a cold end heat exchanger fin 221 and a first airflow driving device 224. The cold end heat exchanger fin 221 is disposed in the air duct 211 and is used to cool the airflow input from the air inlet 212. The side of the cold end heat exchanger fin 221 facing the air inlet 212 forms the air inlet side of the dehumidification component 22; the first airflow driving device 224 is disposed in the air duct 211, and the first airflow driving device 224 is used to transport the airflow from the air inlet 212 to the air outlet 213.

[0070] The cold end heat exchanger 221 is used to perform heat exchange with the airflow entering the air duct 211, so that the airflow entering the air duct 211 can be condensed at the cold end heat exchanger 221, and the water vapor forms condensed water. The side of the cold end heat exchanger 221 facing the air inlet 212 forms the air inlet side of the dehumidification component 22, and the side of the dehumidification component 22 away from the air inlet 212 can form its outlet side. The airflow enters the air duct 211 from the air inlet 212, exchanges heat with the cold end heat exchanger 221, and then flows toward the air outlet 213.

[0071] The first airflow driving device 224 is used to provide power so that the airflow can have a tendency to flow from the air inlet 212 to the air outlet 213. The first airflow driving device 224 in this example can be a fan. The first airflow driving device 224 can be installed near the air inlet 212 or the air outlet 213, or the first airflow driving device 224 can be arranged near the dehumidification component 22. Optionally, the first airflow driving device 224 can be arranged on the air outlet side of the dehumidification component 22.

[0072] In this example, the airflow can be driven by the first airflow driving device 224. When the airflow passes through the dehumidification component 22, it can exchange heat with the cold end heat exchange plate 221 of the dehumidification component 22, so that the water vapor in the airflow condenses to form condensed water to reduce the water content of the airflow. When the airflow passes through the smoke sensing component 25, the airflow can be detected by the smoke sensing component 25. In some examples, a motor 225 for driving the first airflow driving device 224 is provided on the mounting shell 21. The installation position of the motor 225 can be adapted to the position of the first airflow driving device 224. For example, the first airflow driving device 224 is installed on the side of the dehumidification component 22 facing the air outlet 213. The motor 225 can be installed on the wall where the air outlet 213 is located.

[0073] In some examples, a heat exchange device for cooling the cold end heat exchange fins 221 is provided on the mounting shell 21. The heat exchange device can be used to reduce the temperature of the cold end heat exchange fins 221, thereby condensing water vapor in the air into condensed water when contacting the cold end heat exchange fins 221.

[0074] In some examples, the mounting shell 21 has a drain port 214, and the drain port 214 is used to discharge the condensed water of the cold end heat exchanger fin 221 to the outside of the mounting shell 21. The drain port 214 can be a through hole opened on the mounting shell 21. The drain port 214 is used to discharge the condensed water accumulated in the mounting shell 21. Optionally, a water pump for pumping out the condensed water is provided in the mounting shell 21 to reduce the accumulation of condensed water in the mounting shell 21. In some examples, a drain pipe 216 connected to the drain port 214 is provided on the mounting shell 21. When the mounting shell 21 is installed in the cabinet 100, the drain pipe 216 can be connected to the outside of the cabinet 100.

[0075] In some examples, the mounting shell 21 has a bottom wall 215 , the cold end heat exchange fins 221 are at least partially disposed obliquely relative to the bottom wall 215 , and the drain port 214 is disposed on the bottom wall 215 .

[0076] The bottom wall 215 may be a wall surface of the mounting shell 21 located at the bottom of the mounting shell 21. When the condensed water on the cold end heat exchanger fins 221 falls under the action of gravity, the condensed water may drip onto the bottom wall 215. In this example, the bottom wall 215 may be arranged parallel to the horizontal plane.

[0077] The cold end heat exchange fin 221 is at least partially inclined relative to the bottom wall 215, which means that the cold end heat exchange fin 221 has at least one surface inclined relative to the bottom wall 215, and the condensed water on the cold end heat exchange fin 221 can flow along the surface inclined relative to the bottom wall 215 under the action of gravity, so that the condensed water can gather toward the bottom wall 215 to reduce the residence time of the condensed water on the cold end heat exchange fin 221. In this example, the cold end heat exchange fin 221 can be at least partially in a sheet structure to increase the heat exchange area between the cold end heat exchange fin 221 and the airflow, and the cold end heat exchange fin 221 can be inclined relative to the bottom wall 215 as a whole.

[0078] In some examples, the dehumidification component 22 also includes a hot-end heat exchanger fin 222, which is disposed between the cold-end heat exchanger fin 221 and the air outlet 213 and is used to heat the airflow output from the cold-end heat exchanger fin 221. The side of the hot-end heat exchanger fin 222 facing the air outlet 213 forms the air outlet side of the dehumidification component 22.

[0079] The hot end heat exchanger 222 is used to perform heat exchange with the airflow output from the cold end heat exchanger 221 to increase the temperature of the airflow. The side of the hot end heat exchanger 222 facing the air outlet 213 forms the outlet side of the dehumidification component 22. The airflow enters the air duct 211 from the air inlet 212. When the airflow is at the cold end heat exchanger 221, the water vapor in the airflow performs heat exchange with the cold end heat exchanger 221 to reduce the content of water vapor in the airflow. When the airflow continues to flow toward the hot end heat exchanger 222, the temperature of the airflow increases under the action of the hot end heat exchanger 222. In this example, the hot end heat exchanger 222 performs heat exchange with the air, which can increase the temperature inside the installation shell 21, thereby helping to further reduce the humidity of the air between the outlet side of the dehumidification component 22 and the air outlet 213, and reduce the false alarm of the smoke sensing component 25 due to the influence of water vapor.

[0080] Optionally, a heat exchange device for increasing the temperature of the hot-end heat exchange fins 222 may be provided on the mounting shell 21, so that the temperature of the hot-end heat exchange fins 222 can be increased.

[0081] In some examples, the dehumidification component 22 also includes a semiconductor refrigeration plate 223, which is connected between the cold end heat exchange plate 221 and the hot end heat exchange plate 222. The semiconductor refrigeration plate 223 is used to control the cold end heat exchange plate 221 for cooling and control the hot end heat exchange plate 222 for heating.

[0082] The semiconductor refrigeration sheet 223 is arranged between the cold end heat exchange sheet 221 and the hot end heat exchange sheet 222. The semiconductor refrigeration sheet 223 utilizes the Peltier effect of semiconductor materials. When direct current passes through a couple formed by two different semiconductor materials in series, heat can be absorbed and released at both ends of the couple, respectively, to achieve the purpose of refrigeration. The semiconductor refrigeration sheet 223 is a refrigeration technology that generates negative thermal resistance, and its characteristic is that heat is transferred from the cold end to the hot end, thereby completing the refrigeration of the cold end.

[0083] In this example, the semiconductor refrigeration plate 223 and the cold end heat exchange plate 221 and the hot end heat exchange plate 222 form a whole, so as to realize cooling of the cold end heat exchange plate 221 and heating of the hot end heat exchange plate 222 .

[0084] In some examples, the smoke detection device 20 also includes a humidity detection module 23, which is connected to the mounting shell 21 and is used to detect a humidity signal in the mounting shell 21. The dehumidification component 22 is electrically connected to the humidity detection module 23, and the dehumidification component 22 is used to dehumidify the airflow according to the humidity signal. The humidity detection module 23 can be used to detect the humidity in the air to obtain a humidity signal. When the humidity reaches a preset humidity, the dehumidification component 22 can start to operate to dehumidify the air. The dehumidification component 22 in this example can operate intermittently according to the ambient humidity state. When the ambient humidity is lower than the preset humidity, the dehumidification component 22 can be shut down or standby. When the ambient humidity is higher than the preset humidity, the dehumidification component 22 performs a dehumidification operation again to improve the working efficiency of the dehumidification component 22 and reduce energy consumption.

[0085] In some examples, the smoke detection device 20 further includes a dustproof mesh cover 26, which is disposed at the air inlet 212. The dustproof mesh cover 26 can be used to block or absorb dust in the airflow entering the air inlet 212 to reduce dust from entering the air duct 211. The dustproof mesh cover 26 in this example can be fixedly or detachably connected to the air inlet 212 of the mounting shell 21.

[0086] In some examples, the smoke detection device 20 further includes a dust cleaning component 27, which is movably connected to the mounting shell 21 or the dustproof net cover 26, and is used to clean the dust on the dustproof net cover 26.
