Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting equipment, in particular to a temperature-sensitive fire detection alarm. Background Art

[0002] Wireless independent thermal fire detection alarm is a device used to monitor fire and sound an alarm. It is widely used because it can help detect fire early so that appropriate measures can be taken to protect the safety of people and property. This device warns of fire by sensing temperature changes in the surrounding environment. However, the current traditional thermal fire detection alarm has some significant shortcomings, because it can only alert the fire through the buzzer alarm on the spot, so as to evacuate and escape. It makes it impossible for users to monitor the alarm status in real time, and it is difficult to remotely control and maintain it. For communities, residential areas, alarm rooms or users who are not at home, it is impossible to notify the alarm information in time, so that the fire fighting and rescue time is delayed. In addition, due to the lack of remote communication capabilities, the traditional independent thermal detector cannot timely understand whether the equipment installed on site has abnormalities, so that the equipment cannot play a protective role when a fire occurs. At the same time, the traditional wireless independent thermal fire detection alarm cannot record and store alarm data, making the subsequent analysis and investigation of fire alarm incidents difficult.

[0022] The present utility model embodiment provides a temperature-sensitive fire detection alarm 100, such as Figure 1 and Figure 2As shown, the temperature-sensing fire detection alarm 100 includes: an upper shell 110, a base 120 and a circuit board 130. The upper shell 110 is provided with an air inlet 111. The upper shell 110 and the base 120 are detachably connected to form a receiving cavity, and the air inlet 111 is connected to the receiving cavity. The circuit board 130 is located in the receiving cavity. The circuit board 130 includes a temperature sensing module, a data processing module, a communication module, an alarm module and a storage module (not shown in the figure). The temperature sensing module is electrically connected to the alarm module through the data processing module, the communication module is electrically connected to the data processing module, and the storage module is electrically connected to the data processing module. The communication module is used for wireless communication with an external device to transmit an alarm signal and / or log data, and the storage module is used for storing alarm event data.

[0023] The working principle and beneficial effects of the above technical solution are as follows: During the installation process, the circuit board 130 of the temperature-sensitive fire detection alarm 100 is installed in the accommodating cavity formed by the upper shell 110 and the base 120, and the circuit board 130 is installed as a whole in a preset installation position such as the indoor roof. During operation, when the temperature sensing module of the temperature-sensitive fire detection alarm 100 detects a temperature change, the sampled value is sent to the data processing module, and it is determined whether an alarm needs to be issued according to the preset alarm conditions. If an alarm needs to be issued, the data processing module controls the alarm module to issue a corresponding alarm prompt, complete the local sound and / or light alarm, and at the same time, the latest local status is sent to other alarms or transceiver systems and the central control center through the communication module. In addition, the data processing module records the alarm event and related data in the storage module to form an alarm data log. The communication module allows the alarm module to communicate with external systems such as smart home platforms or fire monitoring centers to transmit alarm signals and log data. The storage module can store alarm data logs for subsequent analysis and investigation. The wireless communication method of the communication module can realize remote monitoring and control, improve user convenience, and help improve the intelligence level of the fire detection system, and further improve the accuracy and response speed of fire warning.

[0024] Furthermore, the communication module has a secure radio communication capability based on wireless communication technology by using wireless communication technology, including NB-IOT, CAT1, SUB 1G, Bluetooth, WiFi or other wireless networks, which is conducive to solving the limitation that traditional wireless independent temperature detectors can only alarm through local sound prompts. Furthermore, the data is reported to the cloud service center, and the user is notified through APP, phone, SMS, etc., which is conducive to improving the reliability of the notification.

[0025] In one embodiment, see Figure 2The temperature-sensing fire detection alarm 100 further includes a mounting frame 140 , the upper shell 110 and the base 120 are detachably mounted on opposite sides of the mounting frame 140 , and the circuit board 130 is connected to the mounting frame 140 .

[0026] The working principle and beneficial effects of the above technical solution are: on the one hand, the overall structural stability of the temperature-sensitive fire detection alarm 100 is improved, and on the other hand, the installation and maintenance of components are facilitated.

[0027] In one embodiment, see Figure 2 The mounting frame 140 further includes a battery compartment 141 , which is electrically connected to the circuit board 130 and is used for installing batteries.

[0028] The working principle and beneficial effects of the above technical solution are as follows: the battery-powered mode does not require an external power supply, is easy to install, and can also operate independently when a fire occurs, which is conducive to improving working reliability.

[0029] In one embodiment, see Figure 2 The circuit board 130 further includes a separation detection module 131, which is disposed in the accommodating cavity. The separation detection module 131 is electrically connected to the data processing module, and the base 120 and the separation detection module 131 are in contact with each other. When the base 120 is separated from the mounting bracket 140, the separation detection module 131 sends a separation signal to the data processing module.

[0030] The working principle and beneficial effects of the above technical solution are as follows: when the main body composed of the upper shell 110 and the mounting bracket 140 of the alarm is installed or removed, the movement of the main body and the base 120 will trigger the separation detection module 131, and this module will send the corresponding status to the signal processing module. The signal processing module will send the latest local separation status to other alarms or transceiver systems and the central control center through the wireless communication of the communication module according to the preset logic, thereby obtaining the removal status.

[0031] Specifically, see Figure 2 The separation detection module 131 includes a detection body, a detection block 132 and a reset member (not shown in the figure). The detection block 132 is reset and matched with the detection body through the reset member, and the detection block 132 is pressed and matched with the base 120.

[0032] Optionally, the reset element may be a spring, a spring, an elastic foam or other elastic or rigid reset mechanism.

[0033] The working principle and beneficial effects of the above technical solution are as follows: when the base 120 and the mounting frame 140 are installed, the detection block 132 presses against the base 120, which is a normal installation state. When the base 120 is deformed and the gap changes, the reset member can still give the detection block 132 a reset force, so that the detection block 132 and the base 120 form a press, so that the separation detection unit has the ability to resist the deformation of the base 120, which is conducive to solving the problem of false separation alarm caused by abnormal installation of the base 120.

[0034] In one embodiment, see Figure 2 The temperature-sensing fire detection alarm 100 also includes an indicator light and a light guide column 150. The indicator light is located on the circuit board 130. The light guide column 150 is connected to the upper shell 110. The upper shell 110 is provided with an indication hole. The light guide column 150 is plugged into the indication hole. The indicator light has at least two indication colors.

[0035] Specifically, the indicator lights respectively indicate the operating status, registration indication, deregistration indication, alarm indication, and wireless communication signal indication.

[0036] The working principle and beneficial effects of the above technical solution are: different states are indicated by different colors and different display modes, which is convenient for users and installers to use and install. The light guide column 150 can export the LED light source on the circuit board 130, and the display is more intuitive.

[0037] In one embodiment, see Figure 1 and Figure 2 The temperature-sensing fire detection alarm 100 also includes an air inlet guide plate 160 , which is provided with a plurality of guide grooves 161 , and a plurality of air inlet holes 111 , which are arranged at intervals along the circumference of the upper shell 110 , and the guide grooves 161 are arranged corresponding to the air inlet holes 111 .

[0038] The working principle and beneficial effects of the above technical solution are as follows: the multiple air inlet holes 111 can improve the air intake efficiency, the guide grooves 161 can increase the flue gas flow rate, and also improve the orientation, ensuring that the high-temperature gas can flow into the NTC temperature sensing device located in the middle position, thereby improving working reliability.

[0039] In one embodiment, see Figure 2 The alarm module includes an alarm circuit and a buzzer 170, and the buzzer 170 is electrically connected to the data processing module through the alarm circuit.

[0040] The working principle and beneficial effects of the above technical solution are as follows: when the temperature sensing module of the temperature-sensing fire detection alarm 100 detects temperature changes, the sampling value is sent to the signal processing module, and it is determined whether an alarm needs to be issued based on the preset alarm conditions. If an alarm needs to be issued, the signal processing module controls the alarm module to issue a corresponding alarm sound through the buzzer 170 module, thereby completing a local sound and / or light alarm. The combination of temperature sensing and data processing ensures that the alarm can be triggered quickly and accurately to alert indoor personnel when abnormal temperature is sensed.

[0041] In one embodiment, see Figure 2 The communication module is provided with a cellular antenna 180, which is electrically connected to the communication module and is used for sending and receiving wireless communication signals.

[0042] The working principle and beneficial effects of the above technical solution are: the operator's wireless network can be used for signal transmission through the cellular antenna 180, thereby improving applicability and convenience of use.

[0043] Different from the above embodiment, in another embodiment, the communication module is further provided with a private network antenna 190 , see 2 , the private network antenna 190 is electrically connected to the communication module, and the communication module performs wireless communication via the private network antenna 190 .

[0044] It should be noted that Figure 2 The cellular antenna 180 and the private network antenna 190 are presented in the same schematic diagram only for illustrating and explaining two different embodiments of the utility model, and does not mean that the two appear in the same temperature-sensing fire alarm 100, that is, the cellular antenna 180 and the private network antenna 190 are selected for use.

[0045] The working principle and beneficial effects of the above technical solution are: the dedicated network antenna 190 can make the device dedicated to the network, use the self-built network for communication, have high security, and dedicated resources can be deployed.

[0046] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
