Description

Technical Field

[0001] This application relates to the field of detection and alarm technology, and in particular to a fire smoke detection and alarm device. Background Technology

[0002] The production, packaging, and storage of Maotai-flavor liquor all require a large amount of flammable and combustible materials, leading to a high fire hazard in production and operation sites. Therefore, smoke detectors are typically installed to detect and handle initial fires promptly, minimizing losses. However, the presence of numerous Aspergillus mosquitoes in the Maotai-flavor liquor production environment—mosquitoes much smaller than common insects—allows them to enter smoke detectors. These mosquitoes can cause malfunctions in the sensing units even when no fire is present, resulting in false alarms. This can severely disrupt production and operations, and increase daily maintenance costs for businesses.

[0003] Although most businesses now use insect-proof fire smoke detectors, which have a protective mesh installed on them to prevent insects from entering.

[0004] However, the above methods can only effectively prevent insects and debris with a body length of 5 mm or more from entering the equipment. They cannot effectively prevent mosquitoes with a body length of about 1.5 mm from entering. As a result, mosquitoes in the production site of Maotai-flavor liquor can enter the fire smoke detector and become active or reproduce, causing frequent false alarms, shortening the lifespan of the detector, and increasing the maintenance costs of enterprises.

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0042] In existing technologies, fire smoke detection alarm devices rely solely on a single protective mesh to passively prevent insects from entering. This is only effective against insects and debris longer than 5 mm, failing to prevent mosquitoes (approximately 1.5 mm in length) from entering. Consequently, mosquitoes from the production site of Maotai-flavor liquor can enter the smoke detector, causing frequent false alarms, shortening its lifespan, and increasing maintenance costs. Therefore, this application provides a fire smoke detection alarm device that, through the cooperation of a detector housing 1, a central processing module, a sensing module 3, and a mosquito repellent module, can actively repel mosquitoes while monitoring smoke concentration. This prevents mosquitoes from entering the smoke detection alarm device, thus avoiding frequent false alarms, shortened lifespan, and increased maintenance costs. Simultaneously, it improves the accuracy of the smoke detection alarm.

[0043] The following detailed description of a fire smoke detection and alarm device provided in this embodiment, with reference to the accompanying drawings, is provided in detail. Figure 1 , Figure 2 As shown, the detector housing 1 includes a central processing module, a sensing module 3, and a mosquito repellent module disposed inside the detector housing 1. The central processing module is electrically connected to the sensing module 3 and the mosquito repellent module. The detector housing 1 provides installation support and facilitates the use of the central processing module, the sensing module 3, and the mosquito repellent module. The central processing module monitors the signals from the sensing module 3 and the mosquito repellent module and, in conjunction with the detector housing 1, transmits the signals to the area to be detected. The sensing module 3, in conjunction with the detector housing 1, detects the concentration of smoke, generates a smoke alarm signal based on the concentration, and transmits the smoke alarm signal to the central processing module. The mosquito repellent module, in conjunction with the detector housing 1, repels mosquitoes into the detector housing 1 and generates a repelling signal, which is then transmitted to the central processing module.

[0044] Here, since the detector housing 1 has a hollow interior, the central processing module, the sensor detection module 3, and the mosquito repellent module can all be installed within this cavity. Specifically, since the detection alarm device needs to be installed at the location to be detected when detecting fire smoke, the detector housing 1 can provide a mounting support to cooperate with the mounting base at the location to be detected for installation. Simultaneously, the detector housing 1 can be used in conjunction with the central processing module, the sensor detection module 3, and the mosquito repellent module to enable them to perform their respective functions.

[0045] In one feasible implementation, the central processing module includes, but is not limited to, a central processing unit 2 (since the central processing unit is the control center of the entire detection and alarm device, its specific location is not fixed; this is just a simplified illustration). It is the core component of the computer system, responsible for executing preset instructions, processing data, and controlling the coordinated operation of other hardware components. Therefore, the central processing unit 2 can monitor the signals from the sensing module 3 and the mosquito repellent module, and cooperate with the detector housing 1 to transmit the signals to the area to be detected. The sensing module 3 is the core component of the fire smoke detection and alarm device. It can monitor the smoke concentration in the environment in real time, generate a smoke alarm signal based on this concentration, and transmit the smoke alarm signal to the central processing module. The mosquito repellent module can repel mosquitoes, cooperating with the detector housing 1 to repel mosquitoes into the detector housing 1, and generating a repelling signal, which is then transmitted to the central processing module.

[0046] The above operation, through the cooperation of the detector housing 1, the central processing module, the sensing and detection module 3, and the mosquito repellent module, can monitor the smoke concentration while actively repelling mosquitoes. This prevents mosquitoes from entering the smoke detection alarm device, thus avoiding frequent false alarms, shortening the lifespan of the detector, and increasing the maintenance costs for enterprises. At the same time, it can improve the detection accuracy of the smoke detection alarm device.

[0047] Preferably, continue to refer to Figure 1 , Figure 2 As shown, the detector housing 1 includes a detector base 11 and a main body shell 12 disposed on the upper surface of the detector base 11; the detector base 11 is used to provide installation support, cooperate with the installation seat of the place to be detected, and cooperate with the central processing module to realize signal transmission; the main body shell 12 is used to cooperate with the sensing and detection module 3 and the mosquito repelling module to realize the detection of smoke concentration in the place to be detected and the repulsion of mosquitoes.

[0048] In one feasible approach, refer to Figure 1 , Figure 2 As shown, the upper surface of the detection base 11 is provided with a circuit board, which is used to provide signal support for the central processing module, the sensing and detection module 3 and the mosquito repellent module; the lower surface of the detection base 11 is provided with a buckle 111, which is used to install the detection base 11 in conjunction with the mounting base of the place to be detected.

[0049] Specifically, such as Figure 1 , Figure 2As shown, a circuit board is detachably connected to the upper surface of the detection base 11. This circuit board provides signal support for the central processing unit 2, the sensing module 3, and the mosquito repellent module, facilitating the transmission of signals from each component. The detection base 11 can be circular. Four clips 111 are fixedly connected to the lower surface of the detection base 11. These four clips 111 are evenly spaced along the outer periphery of the detection base 11, and the side of each clip 111 furthest from the detection base 11 can engage with a mounting base at the location to be monitored. Since the mounting base has a slot, the clips 111 allow for a snap-fit ​​connection between the detection base 11 and the mounting base. Simultaneously, the central processing unit 2 is detachably connected to the detection base 11. One end of each clip 111 can be electrically connected to the central processing unit 2, and the other end can be electrically connected to the mounting base at the location to be monitored. The mounting base also has a circuit board, enabling the central processing unit 2 to receive a signal and transmit it to the mounting base, which in turn transmits it to the fire control system of the location to be monitored, facilitating timely early warning.

[0050] The above operation, by setting a circuit board and a clip 111 on the detection base 11, enables the central processing unit 2 to obtain the transmission signal and then transmit the transmission signal to the mounting base, and then from the mounting base to the fire control system of the place to be detected, so as to provide timely early warning.

[0051] In one feasible approach, refer to Figure 2 , Figure 3 As shown, the main body shell 12 is provided with a smoke inlet 121 for smoke from the area to be detected to enter the detector shell 1; the sensing and detection module 3 is used to monitor the smoke concentration of the detector shell 1 to generate a smoke alarm signal and transmit the smoke alarm signal to the central processing module.

[0052] Here, as Figure 2 , Figure 3 As shown, the outer peripheral surface of the main body shell 12 near its upper end is provided with a plurality of smoke inlets 121. The plurality of smoke inlets 121 are evenly distributed at equal intervals along the outer peripheral surface of the main body shell 12 so that smoke can enter the detector housing 1.

[0053] The sensing module 3 can monitor the smoke concentration entering the detector housing 1 from the smoke inlet 121, generate a smoke alarm signal, and transmit the smoke alarm signal to the central processing unit 2.

[0054] The above operation, through the cooperation of the smoke inlet 121 and the sensing module 3, can monitor the concentration of smoke entering the detector housing 1, so as to trigger the corresponding alarm operation.

[0055] In one feasible approach, refer to Figure 2 The main body shell 12 is provided with a primary protective net 122 at the position of the smoke inlet 121 to prevent primary debris from entering.

[0056] Among them, Level 1 debris refers to objects of a specific size that are pre-defined at Level 1, and debris includes, but is not limited to, insects and other substances.

[0057] Here, as Figure 2 , Figure 3 As shown, the main body shell 12 is provided with a primary protective net 122, i.e. a coarse protective net, at the position of the smoke inlet 121. The protective net is an 80-mesh protective net with a mesh structure. The primary protective net 122 is fixedly connected to the inside of the smoke inlet 121 to serve as the "first line of defense" for the smoke detector to filter out debris.

[0058] The above operation, through the setting of the primary protective net 122, can prevent non-fire smoke debris from entering the detector housing 1, thereby preventing frequent false alarms of the smoke detection alarm device and shortening the service life of the smoke detection alarm device.

[0059] In one feasible approach, refer to Figure 2 , Figure 4 The sensing and detection module 3 includes a photoelectric sensing and detection unit 31; the photoelectric sensing and detection unit 31 includes a photoelectric maze 312 disposed on the detection base 11, and a light emitter 311 and a light receiver 313 disposed on the photoelectric maze 312; the light emitter 311 is used to emit light within the photoelectric maze 312; the photoelectric maze 312 is used to scatter and reflect the light emitted by the light emitter 311 according to the smoke concentration inside the detector housing 1; the light receiver 313 is used to receive the light scattered and reflected by the photoelectric maze 312, and to generate a smoke alarm signal based on the light, and to transmit the smoke alarm signal to the central processing module.

[0060] Specifically, such as Figure 2 , Figure 4As shown, the sensing and detection module 3 includes a photoelectric sensing and detection unit 31. The photoelectric sensing and detection unit 31 includes a photoelectric maze 312 fixedly connected to the detection base 11, and a light emitter 311 and a light receiver 313 located within the photoelectric maze 312. The light emitter 311 and the light receiver 313 are not on the same straight line, and the angle between them can be between 90° and 150°. The light emitter 311 emits light within the photoelectric maze 312. The photoelectric maze 312 can scatter and reflect the light emitted by the light emitter 311 according to the smoke concentration within the detector housing 1. The light receiver 313 can receive the light emitted by the light emitter 311 and scattered and reflected by smoke particles in the photoelectric maze 312. Here, the optical receiver 313 is preset with a light intensity threshold for determining whether a fire has occurred. When the light intensity received by the optical receiver 313 within a certain period of time is less than the light intensity threshold, it indicates that the smoke concentration is low, and the optical receiver 313 determines that no fire has occurred, so no operation is required and the current state can be maintained. When the light intensity received by the optical receiver 313 within a certain period of time is greater than the light intensity threshold, the optical receiver 313 determines that a fire has occurred, indicating that the smoke concentration is high, so a smoke alarm signal is generated and transmitted to the central processing unit 2. The central processing unit 2 then transmits the smoke alarm signal to the mounting base at the location to be detected, and the smoke alarm signal from the mounting base at the location to be detected is transmitted to the fire control system for early warning.

[0061] In one feasible approach, refer to Figure 4 As shown, a secondary protective net 3121 is provided on the outside of the photoelectric maze 312 to prevent secondary debris from entering.

[0062] Among them, secondary debris refers to objects of a specific size that are pre-defined at the secondary level. Debris includes, but is not limited to, mosquitoes with a body length of about 1.5 mm and other substances.

[0063] Here, as Figure 4 As shown, a secondary protective net 3121, or fine protective net, is fitted around the outside of the photoelectric maze 312. This fine protective net has a "mesh structure" and is a 100-mesh protective net, which is arranged around the outside of the photoelectric maze 312. The mesh size of the secondary protective net 3121 is sufficient to allow smoke particles to enter the photoelectric maze 312 while blocking mosquitoes and other substances from entering the photoelectric maze 312.

[0064] The above-mentioned operation, the setting of the secondary protection net 3121, can block debris other than smoke particles, such as mosquitoes, from entering the photoelectric maze 312, and prevent the light emitted from the light emitter 311 from being reflected by debris in the photoelectric maze 312 and entering the light receiver 313, thereby increasing the amount of light received by the light receiver 313 and causing false alarms of the smoke detection alarm device.

[0065] In one feasible manner, continue to refer to Figure 2 , Figure 4 The sensing and detection module 3 also includes an ion sensing and detection unit; the ion sensing and detection unit is used to trigger changes in ion flow based on the smoke concentration inside the detector housing 1 to generate a smoke signal and transmit the smoke signal to the central processing module.

[0066] Here, as Figure 2 , Figure 4 As shown, the sensing and detection module 3 also includes an ion sensing and detection unit, which can be an ion sensing detector 32. Specifically, the ion sensing detector 32 has two ionization chambers: an outer ionization chamber (measuring ionization chamber) that allows smoke particles to enter freely, and an inner ionization chamber (equilibrium ionization chamber) that prevents smoke from entering. A radioactive source within the ionization chamber ionizes the pure air inside, forming positive and negative ions. When a voltage is applied between the two collecting plates within the ionization chamber, an electric field is formed between the plates. Under the influence of this electric field, ions move towards the positive and negative plates respectively, forming an ion flow. Therefore, when smoke particles enter the ionization chamber inside the detector housing 1, because the diameter of the smoke particles is much larger than the diameter of the ionized air particles, the smoke particles have a dual effect of blocking and capturing ions in the ionization chamber, which reduces the ion flow. Under normal conditions, the voltages of the two ionization chambers are nearly equal. However, when smoke particles enter the outer ionization chamber, the voltage of the two ionization chambers is redistributed due to the reduced ion flow. When the voltage change reaches a certain threshold, a smoke alarm signal is generated and transmitted to the central processing unit 2. The central processing unit 2 then transmits the smoke alarm signal to the mounting base at the location to be detected. The smoke alarm signal from the mounting base at the location to be detected is then transmitted to the fire control system for early warning.

[0067] The above operation, by setting up the ion sensing detector 32 and the photoelectric sensing detection unit 31 to form a dual protection, can provide early warning of fires and achieve the effect of preventing fires before they occur.

[0068] In one feasible approach, refer to Figure 2 , Figure 3 As shown, the mosquito repellent module includes an ultrasonic generator unit; the upper surface of the main body shell 12 is provided with a mosquito hole 123, which is used to work with the ultrasonic generator unit to repel mosquitoes; the ultrasonic generator unit emits sound waves of a specific frequency, transmits the sound waves through the mosquito hole 123 to the outside of the main body shell 12 to repel mosquitoes from entering, and generates a repelling signal, and transmits the repelling signal to the central processing module.

[0069] Here, as Figure 2 , Figure 3As shown, the mosquito repellent module includes an ultrasonic generator unit, which can be an ultrasonic generator 4. Multiple curved mosquito holes 123 are provided on the upper surface of the main body shell 12, arranged in a ring. The ultrasonic generator 4 is located on the upper part of the photoelectric labyrinth 312 and is electrically connected to the central processing unit 2. The ultrasonic generator 4 mainly includes sound-generating components, frequency control components, and power amplification components. It can convert electrical energy into ultrasonic signals of a specific frequency. By emitting ultrasonic signals of a specific frequency, which can be set to sound waves of 20kHz to 55kHz, the sound waves are transmitted through the curved mosquito holes 123 to the outside of the main body shell 12 to interfere with the nervous system of mosquitoes and other insects, thereby repelling them from entering. Simultaneously, it can also generate a repelling signal and transmit it to the central processing unit 2 so that the central processing unit 2 can determine whether it is damaged.

[0070] The above operation, through the cooperation of the mosquito hole 123 and the ultrasonic generator 4, actively repels mosquitoes and other insects around the fire smoke detector, further reducing the probability of mosquitoes and other insects approaching and entering the detector, thereby reducing the false alarm rate of the fire smoke detector and extending its service life.

[0071] In one embodiment, refer to Figure 1 , Figure 2 As shown, the main body housing 12 is equipped with a status indicator light 5, which is electrically connected to the central processing module and is used to indicate the current status of the fire smoke detection alarm device.

[0072] Here, the main body shell 12 is also equipped with a status indicator light 5, which is electrically connected to the central processing unit 2 and is used to indicate the current status of the fire smoke detection alarm device. When the central processing unit 2 receives a smoke alarm signal, it can control the status indicator light 5 to light up red; when the fire smoke detection alarm device is in normal condition, the status indicator light 5 can always remain in the green light state.

[0073] The above operation, by setting status indicator light 5, allows staff to easily determine the current status of the smoke detection alarm device, so that staff can provide timely fire warnings.

[0074] The overall implementation principle of this embodiment is as follows: After the smoke detection alarm device is installed in the location to be detected, firstly, the photoelectric sensing detection unit 31 and the ion sensing detector 32 jointly monitor the working status of the smoke detection alarm device in real time. When the smoke concentration inside the smoke detection alarm device is detected to be too high, a smoke alarm signal is generated and transmitted to the central processing unit 2. The central processing unit 2 then transmits the smoke alarm signal to the mounting base in the location to be detected. The smoke alarm signal from the mounting base in the location to be detected is then transmitted to the fire control system for early warning. Secondly, the ultrasonic generator 4 emits sound waves of a specific frequency to actively repel insects such as mosquitoes around the fire smoke detection alarm device, thereby reducing the probability of these insects approaching and entering the detector, thus reducing the false alarm rate of the fire smoke detection alarm device and extending its service life. Finally, the primary protective net 122 and the secondary protective net 3121 can intercept non-smoke solid materials (floating particles / small animals / insects such as mosquitoes) to prevent them from entering the smoke detection alarm device, further reducing the false alarm rate of the fire smoke detection alarm device.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
