Detailed Embodiments

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0039] Refer to Figure 1, embodiments of the present invention provide a novel smoke sensor device, including: a housing 100, an energy release component 200, and an electric field formation component 300. An air inlet hole is formed on the housing 100. The energy release component 200 is disposed inside the housing 100. The electric field formation component 300 is disposed between the energy release component 200 and the air inlet hole and is electrically connected to the energy release component 200. After an electric field is formed through the electric field formation component 300, it can drive the movement of ions to drive the gas flow outside the housing 100 and converge towards the inside of the housing 100.

[0040] Specifically, the inside of the housing 100 is hollow, so that the energy release component 200 and the electric field formation component 300 can be disposed inside the housing 100. The housing 100 fixes the energy release component 200 and the electric field formation component 300 and protects the energy release component 200 and the electric field formation component 300. Among them, an air inlet hole is formed on the side wall of the housing 100. The electric field formation component 300 is disposed between the energy release component 200 and the air inlet hole and is electrically connected to the energy release component 200. Thus, the energy release component 200 can power on the electric field formation component 300. After the electric field formation component 300 is powered on, an electric field can be formed on the electric field formation component 300. When the electric field is formed, under the action of the electric field, it can drive the movement of ions. Thus, the corresponding gas flow is generated by the ion movement, and further, the gas around the housing 100 can be driven to flow together, so that the gas around the housing 100 converges towards the direction close to the housing 100 until it flows into the housing 100. In practical applications, when the air around the housing 100 converges into the housing 100, it can drive the smoke in the air to converge into the housing 100 together, thus avoiding the situation where the smoke cannot be detected when it is not fully diffused. Even when the housing 100 is directly above the ignition point, it can accurately detect the smoke content in the air at the initial stage of the fire, facilitating accurately judging the location of the ignition point in the first time, avoiding missing the best rescue opportunity, and improving the safety when a dangerous situation occurs.

[0041] In some specific embodiments of the present invention, referring to Figure 3 , the electric field formation component 300 includes: a first pole ring 310 and a second pole ring 320. The first pole ring 310 is sleeved on the inner ring surface of the air inlet hole and is electrically connected to the energy release component 200. The second pole ring 320 is disposed inside the housing 100 and is electrically connected to the energy release component 200. The first pole ring 310 and the second pole ring 320 are electrically connected.

[0042] Specifically, the first pole ring 310 and the second pole ring 320 are correspondingly arranged and electrically connected to each other. The first pole ring 310 and the second pole ring 320 are also respectively electrically connected to the energy release component 200, so that the first pole ring 310 and the second pole ring 320 can be energized through the energy release component 200. After the first pole ring 310 and the second pole ring 320 are respectively energized, an electric field can be formed between the first pole ring 310 and the second pole ring 320. Thus, after the electric field is formed, under the action of the electric field, ions can be driven to move, and the corresponding gas flow can be generated by the ion movement. Furthermore, the gas around the housing 100 can be driven to flow together, so that the gas around the housing 100 converges towards the direction close to the housing 100 until it flows into the housing 100.

[0043] Furthermore, the first pole ring 310 is coaxially sleeved on the inner ring surface of the air inlet hole, and the second pole ring 320 is arranged corresponding to the first pole ring 310, so that the gas around the housing 100 can enter the housing 100 through the central through hole of the first pole ring 310 under the action of ions, facilitating the gas to flow through and enter the housing 100. While guiding the gas flow, the smoothness of the gas flow is ensured, the probability of affecting the smoke content detection result due to the obstruction of the gas flow is reduced, the detection accuracy is further improved, it is convenient to accurately judge the location of the ignition point in the first time, the best rescue opportunity is avoided from being missed, and the safety when the danger occurs is improved.

[0044] In some specific embodiments of the present invention, referring to Figure 3 , both the first pole ring 310 and the second pole ring 320 are spiral structures.

[0045] Specifically, the side walls of the first pole ring 310 and the second pole ring 320 are both spiral shapes similar to a turbine, so that the overall shapes of the first pole ring 310 and the second pole ring 320 respectively form spiral structures. Thus, after the first pole ring 310 and the second pole ring 320 are energized and an electric field is formed, under the action of the spiral-structured first pole ring 310 and second pole ring 320, ions can be driven to move in a spiral shape, and a spiral gas flow can be correspondingly generated. Furthermore, the gas around the housing 100 can be driven to flow in a spiral shape together. In this way, the speed of converging the gas can be accelerated, so that the smoke content can be detected in the first time, and the force of converging the gas can be increased to expand the radiation range of the new smoke sensing device, thus ensuring the accuracy of the smoke content detection result and avoiding large deviations in the detection result due to special situations such as uneven smoke dispersion.

[0046] In some specific embodiments of the present invention, referring to Figure 1, there are multiple air inlets, and the multiple air inlets are arranged in a circumferential ring around the housing 100. There are multiple first pole rings 310 and multiple second pole rings 320 respectively, and there is a one-to-one correspondence among the multiple air inlets, the multiple first pole rings 310 and the multiple second pole rings 320.

[0047] Specifically, the multiple air inlets are evenly distributed around the circumference of the housing 100, and the multiple first pole rings 310 are arranged in one-to-one correspondence with the multiple air inlets. The first pole ring 310 is coaxially sleeved on the inner ring surface of the air inlet. The multiple second pole rings 320 are arranged in one-to-one correspondence with the multiple first pole rings 310, and the second pole ring 320 is coaxially and oppositely arranged with the corresponding first pole ring 310. By increasing the number of settings of the air inlets and the corresponding first pole rings 310 and second pole rings 320, the strength and speed of gas gathering are further improved, and the smoke content can be accurately detected in the first time.

[0048] Furthermore, there are multiple connecting columns 321 arranged on the inner wall of the housing 100. The multiple connecting columns 321 are arranged in one-to-one correspondence with the multiple pole rings. Both ends of the connecting column 321 are connected to the inner wall of the housing 100 and the outer ring surface of the corresponding second pole ring 320 respectively, so as to fix the second pole ring 320 in the housing 100.

[0049] In some specific embodiments of the present invention, refer to Figure 1 , the air inlet is opened on the side wall of the bottom of the housing 100.

[0050] Specifically, the housing 100 is divided into an upper half and a lower half. The air inlet is opened on the side wall of the lower half of the housing 100, so that it can be relatively close to the ignition point in case of danger and is convenient for gathering the surrounding gas.

[0051] Furthermore, the whole of the housing 100 is in an inverted convex shape, so that the width of the upper half of the housing 100 is greater than the width of the lower half of the housing 100. The air inlet is opened in the lower half with a smaller width, which is further convenient for gathering the surrounding gas, so as to ensure the accuracy of the smoke content detection result.

[0052] In some specific embodiments of the present invention, refer to Figure 3 and Figure 4 , the energy release component 200 includes: a battery 210 and a capacitor 220. Electric energy is stored in the battery 210. The battery 210 is electrically connected to the electric field forming component 300 through the capacitor 220.

[0053] Specifically, the battery 210 is disposed within the housing 100 and is used to store electrical energy. The capacitor 220 is respectively connected to the battery 210, each first pole ring 310, and each second pole ring 320. By means of the capacitor 220, the electrical energy of the battery 210 can be consumed to energize each first pole ring 310 and each second pole ring 320, thereby driving the formation of a battery 210 between each first pole ring 310 and the corresponding second pole ring 320 and enabling ion movement. Furthermore, the corresponding gas flow generated by the ion movement is utilized to drive the gas around the housing 100 to flow together, causing the gas around the housing 100 to converge towards the housing 100 until it flows into the housing 100.

[0054] Furthermore, the capacitor 220 is disposed on the inner bottom wall of the housing 100, thereby being able to reduce the distance between the capacitor 220 and the first pole ring 310 and the second pole ring 320, facilitating layout and distribution.

[0055] In some specific embodiments of the present invention, referring to Figure 4 , a circuit board 120 is disposed within the housing 100. The battery 210 and the capacitor 220 are respectively electrically connected to the circuit board 120. A smoke sensor 121 and a buzzer 122 are also electrically connected and disposed on the circuit board 120.

[0056] Specifically, the circuit board 120 is disposed within the housing 100, and the battery 210 and the capacitor 220 are respectively electrically connected to the circuit board 120, thereby realizing the connection between the battery 210 and the capacitor 220 through the circuit board 120. Moreover, a smoke sensor 121 and a buzzer 122 are also disposed within the housing 100. The smoke sensor 121 detects various other data such as the smoke content in the gas. When the detection result reaches the preset alarm standard, it can send an instruction to the buzzer 122 to drive the buzzer 122 to alarm. At the same time, the smoke sensor 121 and the buzzer 122 are respectively electrically connected and disposed on the circuit board 120, and can be fixed and supported by the circuit board 120, thereby facilitating installation and ensuring the stability of the installation.

[0057] In some specific embodiments of the present invention, referring to Figure 2 , an energy harvesting component 400 is also electrically connected and disposed on the circuit board 120, and is used to harvest radio frequency energy for the battery 210.

[0058] Specifically, the energy harvesting component 400 is disposed on the circuit board 120 and connected to the battery 210. The energy harvesting component 400 can receive external radio frequency signals, collect the energy of the radio frequency signals, and deliver it to the battery 210, thereby charging the battery 210, improving the battery life of the battery 210, enabling long-term power supply to the first pole ring 310 and the second pole ring 320, ensuring the duration of the electric field formed between the first pole ring 310 and the second pole ring 320, promoting the flow of surrounding gas while ensuring energy consumption, performing a long-term gas gathering operation on the surrounding gas, greatly improving the alarm efficiency, and enhancing safety. At the same time, the improvement of the battery life of the battery 210 can also increase the service life of the new smoke sensing device, reduce the maintenance cost, and no longer require replacement of the device in a short time. Moreover, since the battery 210 can be charged through the energy harvesting component 400, electrical energy can be stored in real time. Even if the volume and capacity of the battery 210 itself are correspondingly reduced, it can still meet the operating requirements of the new smoke sensing device, thereby facilitating the optimization of the overall volume and weight of the new smoke sensing device and improving the convenience of use.

[0059] In some specific embodiments of the present invention, referring to Figure 4 , the energy harvesting component 400 includes: a processing module 410, a communication module 420, and a collection circuit module 430. The processing module 410 is electrically connected and disposed on the circuit board 120 for storing data. The communication module 420 is electrically connected and disposed on the circuit board 120 for wirelessly transmitting data. The collection circuit module 430 is electrically connected and disposed on the circuit board 120 for collecting radio frequency energy.

[0060] Specifically, the processing module 410 is disposed on the circuit board 120 and connected to the smoke sensor 121 through the circuit board 120, and can receive the data of the detection result of the smoke sensor 121 and store it. The communication module 420 is disposed on the circuit board 120 and connected to the processing module 410 through the circuit board 120, and can read the data stored in the processing module 410 and send it to the outside. At the same time, the communication module 420 can also receive external radio frequency signals, convert them into corresponding instructions and send them to the smoke sensor 121, thereby realizing the control of the smoke sensor 121. Among them, the communication module 420 can also send some radio frequency signals to the collection circuit module 430, so as to collect radio frequency energy through the collection circuit module 430, charge the battery 210, improve the battery life of the battery 210, reduce the maintenance cost, and facilitate the optimization of the overall volume and weight of the new smoke sensing device.

[0061] Furthermore, the communication module 420 is an existing RFID communication component. Through the RFID communication technology in the communication module 420 and the radio frequency energy collection technology in the collection circuit module 430, combined with the cellular network coverage equipment, the communication module 420 can transmit the data stored in the processing module 410 to the outside by adding an RFID gateway, wherein, since RFID communication belongs to passive communication, the power in the battery 210 will not be consumed when the communication module 420 sends data to the outside. In addition, while the communication module 420 obtains the stored data in the processing module 410 through the RFID communication technology, since the transmission power of the communication module 420 is controllable, the energy of the radio frequency signal reaching the collection circuit module 430 can be increased by increasing the transmission power of the communication module 420. At this time, the radio frequency energy is collected by the collection circuit module 430, and this part of the radio frequency energy can be collected through the battery 210 to complete the charging of the battery 210.

[0062] It should be noted that in actual applications, the cellular network coverage equipment uses the existing indoor distribution system, adds an RFID gateway to the radio frequency system of the indoor distribution system, and then the RFID gateway uses the antenna system of the indoor distribution system to complete the RFID network coverage within a specific area.

[0063] In some specific embodiments of the present invention, an antenna 110 is disposed on the outer wall of the housing 100, and the antenna 110 is electrically connected to the circuit board 120. The antenna 110 can improve the range and accuracy of radio frequency signal reception, thereby facilitating communication and energy collection.

[0064] Communication and charging principle:

[0065] Reference Figure 5 , receiving external radio frequency signals through antenna 110, and converting the received external radio frequency signals through Balun circuit so that they can match the network of communication module 420. Part of the radio frequency signals received by communication module 420 are converted into corresponding instructions and sent to smoke sensor 121 to control smoke sensor 121, while another part of the radio frequency signals received by communication module 420 will reach acquisition circuit module 430, which collects radio frequency energy and charges battery 210, thereby powering smoke sensor 121 and first combination and second pole ring 320. In addition, when smoke sensor 121 obtains corresponding detection data, it will first be sent to processing module 410 for storage, and then processing module 410 will send the corresponding detection data to communication module 420, and then the detection data will be converted again through Balun circuit so that it can match the external network, and then sent to the outside again through antenna 110.

[0066] Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
