[0034] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0035] In view of the problems in the prior art that the alarm function is single and it is difficult to meet the increasing diversified needs of users, the application provides a multifunctional alarm. The multifunctional alarm of the application not only realizes the active alarm function of the multifunctional alarm through the first switch module 12, but also can detect the vibration of the multifunctional alarm through the vibration switch module 13, realize alarm according to the signal of the vibration switch module 13, meet various application scenarios and diversified application needs, ensure safety, and greatly improve user experience.

[0036] The multifunctional alarm will be described below in combination with some specific embodiments.

[0037] Figure 1 A structural schematic diagram of a circuit of the multifunctional alarm of the application is shown. Exemplarily, the multifunctional alarm comprises a shell 21 and a main control circuit board arranged inside the shell 21. It can be understood that the shell 21 of the multifunctional alarm can be arranged according to actual application conditions. The shell 21 can be arranged as an upper shell and a lower shell, or the shell 21 can be arranged as a bottom shell and a face shell. A support can be arranged in the shell 21 to fix the main control circuit board.

[0038] The main control circuit board is provided with a main control module 11, and a first switch module 12, a vibration switch module 13 and an alarm module 14 electrically connected with the main control module 11 respectively. The main control module 11 controls the alarm module 14 to send a first alarm signal after detecting a first preset signal sent by the first switch module 12.

[0039] Exemplarily, the first switch module 12 is a touch switch. The shell 21 of the multifunctional alarm should be provided with a switch assembly corresponding to the first switch module 12. The user triggers the first switch module 12 through the switch assembly. The switch assembly can be a key switch, a toggle switch, a rotary switch, a touch switch, etc. Exemplarily, the structure of the multifunctional alarm is as shown in Figure 2 The position of the shell 21 corresponding to the first switch module 12 is provided with a key groove 22. The first switch module 12 is controlled through the key groove 22. When the key groove 22 is pressed, the first switch module 12 is closed. When the key groove 22 is released, the first switch module 12 is disconnected. The first switch module 12 is controlled through the key groove 22 arranged on the shell 21. Not only is it convenient for the user to identify and operate the switch, but also the multifunctional alarm is improved in appearance and user experience.

[0040] The master module 11 is exemplarily a Bluetooth communication module, which controls the multifunctional alarm according to the received external signal. It can be understood that the Bluetooth communication module can be any Bluetooth communication chip, and the multifunctional alarm communicates with an external terminal such as a computer or a mobile phone through the Bluetooth communication module, and controls the multifunctional alarm according to the signal of the external terminal, for example, the external terminal outputs a signal to control the alarm module 14 to alarm, and the external terminal outputs a signal to control the Bluetooth communication module to detect the vibration state signal. Further, the Bluetooth communication module can transmit alarm information to the external terminal, so that the user can process related matters according to the alarm information, further ensuring the safety of the user.

[0041] Further, the master circuit board is further provided with a second switch module 16 electrically connected with the Bluetooth communication module. After detecting the opening communication signal sent by the second switch module 16, the Bluetooth communication module sends a connection request signal to communicate with the external terminal. Exemplarily, the second switch module 16 is a touch switch, and the shell 21 of the multifunctional alarm is provided with a switch assembly corresponding to the second switch module 16. The user triggers the second switch module 16 through the switch assembly. Exemplarily, the user controls the second switch module 16 through the key switch 23. When the key switch 23 is pressed, the second switch module 16 is closed, and an opening communication signal is output to the Bluetooth communication module. The Bluetooth communication module performs Bluetooth matching, sends a connection request signal, and establishes communication with the external terminal. The control when the Bluetooth communication module is disconnected with the external terminal can be set according to the actual application, for example, when the Bluetooth communication module is in communication connection with the external terminal, the key switch 23 is pressed for three seconds, the Bluetooth communication module is disconnected with the external terminal. Further, the key switch 23 can control the alarm and / or vibration detection of the multifunctional alarm by controlling the second switch module 16.

[0042] After detecting the third preset signal sent by the second switch module 16, the Bluetooth communication module is reset. Exemplarily, the third preset signal is a signal that the second switch module 16 is turned on and then turned off, and then turned on for five seconds. After the user controls the second switch module 16 to be turned on and then turned off through the key switch 23, and then turned on for five seconds, the Bluetooth communication module is reset. Further, the multifunctional alarm can be prompted by sound when starting, shutting down and resetting through the control of the alarm module 14. The connection between the Bluetooth communication module and the external terminal is controlled through the second switch module 16, which can reduce the energy consumption of the multifunctional alarm, realize dynamic management, and also enhance the stability and flexibility of the system.

[0043] The Bluetooth communication module controls the alarm module 14 according to the first preset signal of the first switch module 12. Specifically, the first preset signal can be set according to the actual application. For example, the first preset signal can be set to the signal output after the first switch module 12 is continuously turned on for a preset time. That is, after the user controls the first switch module 12 to be continuously turned on for a preset time through the button slot 22, the Bluetooth communication module controls the alarm module 14 to issue the first alarm signal. Alternatively, the first preset signal can be set to the signal output after the first switch module 12 is turned on or off a preset number of times. That is, after the user controls the first switch module 12 to be turned on or off a preset number of times through the button slot 22, the Bluetooth communication module controls the alarm module 14 to issue the first alarm signal.

[0044] Alternatively, the first preset signal can be set as the signal output by the first switch module 12 after it is switched on and off at a preset frequency. That is, after the user controls the first switch module 12 to switch on and off at a preset frequency through the button slot 22, the Bluetooth communication module controls the alarm module 14 to issue the first alarm signal. For example, the first preset signal is the signal of the first switch module 12 being continuously turned on for three seconds. When the user controls the first switch module 12 to be continuously turned on for three seconds through the button slot 22, the alarm module 14 issues the first alarm signal.

[0045] Specifically, alarm module 14 can be any type of alarm module, and can be configured according to actual application conditions. For example, Figure 3 The diagram shows another circuit structure of the multi-functional alarm. The alarm module 14 includes a sound alarm unit 141 and a light alarm unit 142. The Bluetooth communication module is electrically connected to the sound alarm unit 141 and the light alarm unit 142 respectively. The alarm is triggered by controlling the sound alarm unit 141 and the light alarm unit 142. Different alarm information can be set to different alarm signals according to the actual application. For example, a sound with a preset decibel and a light flashing at a preset frequency can be set as the first alarm signal, or a sound with a preset decibel and a light of a preset color can be set as the first alarm signal, etc. For example, the first alarm signal of the multi-functional alarm is to control the sound alarm unit 141 to generate a sound of 130dB and control the light alarm unit 142 to generate a light flashing at a frequency of 1Hz.

[0046] When a user needs to trigger an alarm, the first switch module 12 is continuously turned on for three seconds via button slot 22. The multi-functional alarm then sounds with a 130dB sound and flashing lights at a 1Hz frequency. To clear the alarm, the user simply presses button slot 22 again. This system enables rapid alarm activation in emergencies, and the dual sound and light alerts significantly improve the efficiency and reliability of the multi-functional alarm, enhancing its warning effect.

[0047] Specifically, the light alarm unit 142 and the sound alarm unit 141 can be set according to actual application, and the light alarm unit 142 is exemplarily shown as a circuit schematic diagram, the Bluetooth communication module controls the frequency of the on and off of the switch tube Q3 to control the flickering frequency of the light-emitting tube D2, and further, a light guide member can be arranged on the shell 21 of the multifunctional alarm to optimize the light propagation path of the light-emitting tube D2 and improve the brightness of the light. Figure 4

[0048] Further, the Bluetooth communication module detects the vibration state signal of the vibration switch module 13 after detecting the second preset signal sent by the first switch module 12, the vibration switch module 13 is used to generate a vibration signal, and the alarm module 14 sends a first alarm signal when the vibration state is detected as vibration. Exemplarily, the second preset signal is a signal that the first switch module 12 is turned on and off and then continuously turned on for five seconds, and the Bluetooth communication module detects the vibration state of the vibration switch module 13 after the user controls the first switch module 12 to be turned on and off and then continuously turned on for five seconds through the key slot 22.

[0049] Further, in order to avoid that the multifunctional alarm cannot be in a stable state after the first switch module 12 is turned on for five seconds, the Bluetooth communication module can be set to detect the vibration state of the vibration switch module 13 after waiting for ten seconds after the first switch module 12 is turned on for five seconds, and the waiting time of ten seconds can be set to count down with a corresponding prompt sound.

[0050] The vibration switch module 13 can be any type of vibration switch, and the vibration switch can be a spherical vibration switch or a spring-type vibration switch, etc. When subjected to vibration, the metal ball or spring sheet in the vibration switch contacts or separates from the contact in the switch under the action of inertia, thereby causing the state of the switch to change. It can be understood that the vibration signal is the signal output by the vibration switch when it is subjected to vibration.

[0051] When the user needs to perform vibration detection, for example, by detecting whether the door and window vibrate to detect whether someone enters, the multifunctional alarm is started in the vibration alarm mode to detect the vibration state of the vibration switch module 13 by controlling the first switch module 12 to be turned on and off through the key slot 22 and then continuously turned on for five seconds, i.e., short pressing once and long pressing for five seconds, and using the waiting time of ten seconds to place the multifunctional alarm on the door and window. When the multifunctional alarm detects that the door and window vibrate, the multifunctional alarm alarms with a sound of 130DB and a light that flickers at a frequency of 1HZ, and the user can eliminate the alarm by pressing the key slot 22 again. By detecting the vibration of the multifunctional alarm, security alarm is realized, which provides more reliable protection for the safety of the user and greatly enhances the confidence of the user. ​

[0052] Further, the multifunctional alarm further comprises a plug-in switch 15 for active alarm, the outer side of the shell 21 is provided with an interface for plugging the plug-in switch 15, the plug-in switch 15 is electrically connected with the Bluetooth communication module through the interface, and the Bluetooth communication module controls the alarm module 14 to send a first alarm signal after detecting a plug-out signal of the plug-in switch 15. The user controls the alarm of the multifunctional alarm through the plug-in switch 15. It can be understood that the plug-in switch 15 can be any shape of switch, and exemplarily, as shown in the figure, the plug-in switch 15 is a pull ring. Figure 2

[0053] Exemplarily, the plug-out signal is a signal when the pull ring is in a plug-out state. When the user pulls out the pull ring, the multifunctional alarm alarms with a sound of 130DB and a light flashing at a frequency of 1HZ. When the user needs to eliminate the alarm, the pull ring is inserted or the key slot 22 is pressed to eliminate the alarm. Through the pull ring, the key slot 22 and the first switch module 12, two active alarm modes of the pull ring and the key are realized, and the alarm can be eliminated by inserting the pull ring or pressing the key slot 22, which greatly improves the reliability of the alarm, increases the success probability of the alarm, adapts to different user needs, and enhances the overall safety guarantee level.

[0054] Further, the Bluetooth communication module controls the light alarm unit 142 to generate a first illumination signal after receiving the fourth preset signal sent by the first switch module 12. Exemplarily, the fourth preset signal is a signal that the first switch module 12 is turned on. When the user controls the first switch module 12 to be turned on through the key slot 22, the Bluetooth communication module controls the light emitting tube D2 of the light alarm unit 142 to be turned on, and the user can use the light of the light emitting tube D2 for illumination. Further, the light of the light emitting tube D2 of the light alarm unit 142 can be set to multiple brightness according to actual application, and the Bluetooth communication module controls the brightness gear of the light according to the received signal.

[0055] ​For example, the light of the light emitting tube D2 is divided into a first illumination signal, a second illumination signal and a third illumination signal, wherein the first illumination signal is a one-grade brightness light, the second illumination signal is a two-grade brightness light, and the third illumination signal is a flashing light. After the Bluetooth communication module generates the first illumination signal and receives the fourth preset signal again, the Bluetooth communication module controls the light and sound alarm unit 142 to generate the second illumination signal. After the light and sound alarm unit 142 generates the second illumination signal and receives the fourth preset signal again, the Bluetooth communication module controls the light and sound alarm unit 142 to generate the third illumination signal. That is, after the Bluetooth communication module receives the signal that the first switch module 12 is turned on, the Bluetooth communication module controls the light and sound alarm unit 142 to generate the one-grade brightness light. After the Bluetooth communication module receives the signal that the first switch module 12 is turned on again, the Bluetooth communication module controls the light and sound alarm unit 142 to generate the two-grade brightness light. After the Bluetooth communication module receives the signal that the first switch module 12 is turned on again, the Bluetooth communication module controls the light and sound alarm unit 142 to generate the flashing light. Further, after the light and sound alarm unit 142 generates the flashing light and receives the signal that the first switch module 12 is turned on again, the Bluetooth communication module controls the light and sound alarm unit 142 to turn off. When the user needs to use the multifunctional alarm for lighting, the multifunctional alarm can be switched between the one-grade brightness light, the two-grade brightness light, the flashing light and the off through short pressing the key slot 22. The multifunctional alarm of the embodiment can realize active alarm and lighting, and can gather multiple functions of alarm and lighting, thereby greatly improving the user experience.

[0056] Further, when the multifunctional alarm is lost, the Bluetooth communication module controls the sound alarm unit 141 to generate the second alarm signal after receiving the device search signal of the external terminal. Illustratively, the second alarm signal is a 60DB sound generated by the sound alarm unit 141. Figure 5 As shown in the circuit schematic diagram of the sound alarm unit 141, the parameters of each component in the circuit can be set according to the actual application. Illustratively, when the Bluetooth communication module controls the switch tube Q1 to be turned on, the sound alarm unit 141 generates a 130DB sound. When the Bluetooth communication module controls the switch tube Q2 to be turned on, the sound alarm unit 141 generates a 60DB sound.

[0057] When the multifunctional alarm is lost, the user can search the multifunctional alarm through the external terminal. The multifunctional alarm alarms with a 60DB sound, which is convenient for the user to find, thereby avoiding the problem that the multifunctional alarm is easily lost in a complex space.

[0058] In an embodiment, on the basis of the above-mentioned embodiment, the multifunctional alarm further comprises a battery module 17 and a charging interface on the shell 21, an input end of the battery module 17 is connected to an external power supply through the charging interface of the shell 21, and the battery module 17 is used to supply power to each module on the main control circuit board. A charging circuit can be arranged to charge the battery module 17, and the charging circuit is exemplarily shown in the following figure, Figure 6 A circuit schematic diagram of a charging circuit 18 of the battery module is shown, the charging current is controlled by using a charging control chip U1, and further, a voltage stabilizing circuit can be arranged to stabilize the signal output by the battery module 17, the stabilized signal is used to supply power to each module on the main control circuit board, and the reliability of the multifunctional alarm is ensured. The battery module 17 is arranged in the multifunctional alarm to supply power to the multifunctional alarm, so that the multifunctional alarm can operate independently, and the flexibility of the multifunctional alarm is greatly improved.
