[0020] Reference Figure 1 , Figure 1The following is a schematic diagram of the structure of an embodiment of the intelligent alarm device 10 for bathrooms of the utility model. In the embodiment shown in the accompanying drawings, the intelligent alarm device 10 for bathrooms includes a plurality of carbon dioxide gas sensors 11 for detecting the carbon dioxide concentration in the bathroom, an alarm component 13, a controller 12, and a power module 14. In this embodiment, the number of the carbon dioxide gas sensors 11 may be four, and the four carbon dioxide gas sensors 11 are distributed on the four walls of the bathroom, and the carbon dioxide gas sensors 11 are close to the floor of the bathroom. In some embodiments, the distance between the carbon dioxide gas sensor 11 and the floor may be 40-55 cm, preferably 50 cm; the alarm component 13 includes a first alarm device 131 installed in the bathroom and a second alarm device 132 installed outside the bathroom. The first alarm device 131 is also provided with A switch button 17 is provided; the controller 12 is connected with the carbon dioxide gas sensor 11, the first alarm device 131, the switch button 17 and the second alarm device 132, and is used to control the first alarm device 131 to alarm when the carbon dioxide concentration in the bathroom exceeds a first preset threshold value, and control the second alarm device 132 to alarm when no signal from the switch button 17 is received within a preset time after the first alarm device 131 alarms; in this embodiment, the controller 12 is implemented by a single-chip microcomputer, and in some other embodiments, the controller 12 can also be implemented by a control chip such as ARM, DSP, etc.; the power module 14 is connected with the carbon dioxide gas sensor 11, the controller 12 and the alarm component 13 to supply power. Based on the above design, since the density of carbon dioxide is greater than that of air, carbon dioxide usually sinks. The carbon dioxide gas sensor 11 is set close to the ground, which can detect the carbon dioxide concentration in the bathroom faster and more accurately. When it is detected that the carbon dioxide concentration exceeds the first preset threshold, the controller 12 controls the first alarm device 131 installed in the bathroom to give an alarm prompt to remind the user that the carbon dioxide concentration in the bathroom is about to exceed the standard, thereby ensuring the user's life safety. After receiving the prompt, the user can press the switch button 17 on the first alarm device 131 to indicate that the alarm prompt has been received. If no signal from the switch button 17 is received within a preset time after the first alarm device 131 gives an alarm prompt, the controller 12 can also control the second alarm device 132 installed outside the bathroom to give an alarm prompt to remind the user's co-residents that the carbon dioxide concentration in the bathroom is about to exceed the standard, thereby further ensuring the user's safety and preventing the user from suffering life-threatening danger due to excessive carbon dioxide concentration.
[0021] Furthermore, in some embodiments, an exhaust fan is installed in the bathroom, and the bathroom intelligent alarm device 10 also includes a relay 15, through which the exhaust fan is connected to the power module 14, and the controller 12 is connected to the relay 15, and is used to control the relay 15 to work when the carbon dioxide concentration in the bathroom exceeds the first preset threshold value / the second preset threshold value so that the power module 14 is connected to the exhaust fan. In the utility model, when the carbon dioxide concentration exceeds the first preset threshold value, it indicates that the carbon dioxide concentration is high, the oxygen is low, and the carbon dioxide concentration is close to the critical value that will cause the user to be hypoxic, and is about to exceed the standard; when the carbon dioxide concentration exceeds the second preset threshold value, it indicates that the carbon dioxide concentration in the bathroom exceeds the standard and reaches the critical value that causes the user to be hypoxic, which is easy to cause the user to feel chest tightness and shortness of breath, and a long duration will also cause syncope. The utility model sets two preset thresholds, the first preset threshold value and the second preset threshold value, to provide users with more reaction time and further ensure life safety. Based on the above design, the utility model is provided with a relay 15 between the exhaust fan and the power module 14 for power supply. Under normal circumstances, the exhaust fan does not work. When the carbon dioxide concentration in the bathroom exceeds the first preset threshold value / the second preset threshold value, the relay 15 connects the exhaust fan and the power module 14, and the exhaust fan works to exhaust and ventilate, thereby improving the air quality in the bathroom.
[0022] In some embodiments, the first alarm device 131 includes a shell (not shown in the figure), a first buzzer 1311 and an LED lamp bead array 1312, the LED lamp bead array 1312 is exposed outside the shell, and includes red lights, yellow lights and green lights arranged at intervals, the controller 12 is located in the shell, and is connected to the first buzzer 1311 and the LED lamp bead array 1312, and the switch button 17 is set on the surface of the shell. In this embodiment, when the carbon dioxide concentration does not exceed the first preset threshold value, the first buzzer 1311 does not make a sound, and the green light in the LED lamp bead array 1312 lights up, indicating that the air quality in the bathroom is good at this time. When the carbon dioxide concentration reaches or exceeds the first preset threshold value, the first buzzer 1311 emits an alarm sound, and the green light in the LED lamp bead array 1312 goes out and the yellow light lights up, prompting the user to open the window for ventilation or manually turn on the exhaust fan, etc. When the carbon dioxide concentration reaches or exceeds the second preset threshold value, the first buzzer 1311 emits an alarm sound, and the yellow light in the LED lamp bead array 1312 goes out and the red light lights up, prompting the user that the carbon dioxide concentration exceeds the standard at this time and it is best to leave the bathroom.
[0023] In this embodiment, the second alarm device 132 includes a second buzzer 1321, and the second buzzer 1321 is connected to the controller 12. Based on this design, when the concentration of carbon dioxide is about to exceed the standard and the first alarm device 131 alarms, but the user does not press the switch button 17 within a preset time (for example, 40 seconds), the controller 12 can control the second buzzer 1321 installed outdoors to sound an alarm to remind the user's cohabitants that the carbon dioxide concentration in the bathroom is about to exceed the standard, thereby further ensuring the safety of the user.
[0024] Furthermore, the bathroom intelligent alarm device 10 also includes a communication module 16, which is connected to the external terminal device 20 and the controller 12, and is used to send a prompt message to the external terminal device 20 when the carbon dioxide concentration in the bathroom exceeds the second preset threshold.

[0025] In some embodiments, the power module 14 includes an AC-DC power conversion unit, which is connected to the carbon dioxide gas sensor 11, the controller 12, the alarm component 13 and the communication module 16. In the present invention, the AC-DC power conversion unit can be connected to the mains to convert the mains into a direct current that meets relevant standards to power each module of the bathroom intelligent alarm device 10.
[0026] Furthermore, the power module 14 may also include a rechargeable battery and a charging circuit, the AC-DC power conversion unit is connected to the rechargeable battery through the charging circuit, and the rechargeable battery is connected to the carbon dioxide gas sensor 11, the controller 12, the alarm component 13 and the communication module 16. It can be understood that the rechargeable battery can be used as a backup power supply to prevent the bathroom intelligent alarm device 10 from interrupting work during a power outage. When there is mains power, the charging circuit uses the mains power to charge the rechargeable battery to ensure the power of the rechargeable battery, so as to ensure that the bathroom intelligent alarm device 10 can work normally during a power outage. The charging circuit and the AC-DC power conversion unit are well known to those skilled in the art and will not be described in detail here.
[0027] In summary, the utility model bathroom intelligent alarm device is provided with a plurality of carbon dioxide gas sensors distributed on different walls of the bathroom to detect the carbon dioxide concentration in the bathroom. Since the carbon dioxide gas sensor is installed on the wall close to the ground, it can quickly detect whether the carbon dioxide concentration is about to exceed the standard. When it is detected that the carbon dioxide concentration exceeds the first preset threshold, the controller controls the first alarm device installed in the bathroom to give an alarm prompt to remind the user that the carbon dioxide concentration in the bathroom is about to exceed the standard, thereby ensuring the user's life safety. After receiving the prompt, the user can press the switch button on the first alarm device to indicate that the alarm prompt has been received. If no signal from the switch button is received within a preset time after the alarm prompt of the first alarm device, the controller can also control the second alarm device installed outside the bathroom to give an alarm prompt to remind the user's co-resident that the carbon dioxide concentration in the bathroom is about to exceed the standard, thereby further ensuring the user's safety and preventing the user from suffering life-threatening danger due to excessive carbon dioxide concentration.
