The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0026] Please also read Figure 1 and Figure 2The voice announcer 100 of the embodiment of the present application includes a plug-in portion 10, a detection component 20 and an electroacoustic element 30. The plug-in portion 10 is detachably connected to the power port 501 of the household appliance 500, and the plug-in portion 10 includes a plug-in circuit, which is electrically connected to the power port 501. The detection component 20 is electrically connected to the plug-in circuit and is used to detect the working electrical signal of the plug-in circuit to output a corresponding detection value, and match a preset sound electrical signal according to the detection value. The electroacoustic element 30 is electrically connected to the detection component 20, and the electroacoustic element 30 is used to obtain the sound electrical signal and convert the sound electrical signal into a sound signal to realize voice broadcasting of the working status of the household appliance 500.

[0027] Thus, the voice announcer 100 can realize the voice announcement function of the household appliance 500. The voice announcer 100 and the household appliance 500 are detachably connected, which can increase the flexibility and convenience of use, realize multiple uses of one object, have a wide range of applications, and effectively reduce costs.

[0029] It is worth mentioning that in the related art, traditional household appliances do not have a voice reminder function, and users can generally only rely on observing whether the physical switch is returned to its position or the way the light is used as a state judgment. When users are doing housework or busy with other affairs, it is easy to ignore the working state of household appliances, so it is necessary to realize the voice broadcast function of the working state of traditional household appliances to solve this problem. There are also many new household appliances on the market that have a voice broadcast function, but this type of household appliances is expensive for traditional household appliances, and the voice broadcast device of this type of household appliances is generally fixed in the household appliances, and the use has limitations.

[0034] In this way, the detection component 20 can output a detection value and match a preset sound electrical signal according to the detection value.

[0035] In some embodiments, the detection value may be a voltage detection value or a current detection value, which is not limited here. The detection circuit 21 is connected to a power supply, the detection circuit 21 is connected to a plug-in circuit, and the detection circuit 21 is also connected to a voice broadcast circuit 30.

[0036] See also Figure 3 In some embodiments, the voice announcer 100 includes a power connection line 40 , and the power connection line 40 is used to connect the power supply and the detection component 20 .

In some embodiments, the power connection line 40 and the voice announcer 100 are detachable, and the two ends of the power connection line 40 are a connecting plug and a mounting portion, respectively. The connecting plug can be used to plug the power supply of the socket, and the mounting portion can be used to connect the detection component 20. The household appliance 500 can obtain the power required for work through the power connection line 40.

[0039] In some embodiments, the voice announcer 100 includes a plurality of plug-in parts 10, and the sizes and shapes of the plurality of plug-in parts 10 may be the same or different, which is not limited here.

In this way, the practicality of the voice announcer 100 is enhanced.

[0040] See also Figure 4In some embodiments, the voice announcer 100 can be designed in the form of a socket panel. The socket panel voice announcer 100 can be fixedly installed on a wall or embedded in the ground. The household appliance 500 includes a power adapter.

The voice announcer 100 also includes a shell, and a sound outlet is opened on the surface of the shell corresponding to the electroacoustic element 30. The sound outlet can make the voice broadcast clearer.

[0041] See also Figure 2 In some embodiments, the detection circuit 21 includes a current transformer 211, a current limiting resistor 212, a photocoupler 213 and a pull-up resistor 214, the input end of the current transformer 211 is connected to the plug-in circuit, the output end of the current transformer 211 is connected to the input end of the current limiting resistor 212, the output end of the current limiting resistor 212 is connected to the input end of the photocoupler 213, and the output end of the photocoupler 213 is connected to the pull-up resistor 214.

[0042] Specifically, the current transformer 211 is connected to the power supply, and the current transformer 211 is also connected to the plug-in circuit. Connecting the current transformer 211 can convert the AC current of the household appliance 500 into a low current, and the low current is output to the input end of the photoelectric coupler 213 after being limited by the current limiting resistor 212. The interior of the photoelectric coupler 213 can achieve proportional output of currents of different sizes and different light intensities, and finally output different voltages through the photoelectric receiving tube at the output end of the photoelectric coupler 213. The output end of the photoelectric coupler 213 is connected to the pull-up resistor 214, and the pull-up resistor 214 will be adjusted according to the different voltages output by the photoelectric coupler 213, so that the detection value can be obtained.

[0043] It is worth mentioning that, in some embodiments, the detection value may be a voltage detection cycle value. The voltage detection cycle value of the household appliance 500 is different in different working states. Figure 5 When the household appliance 500 is not working or the current used by the household appliance 500 is small, the voltage detection cycle value may be maintained at 5V in each power frequency cycle. Figure 6 , when the household appliance 500 is working but the current used by the household appliance 500 is not particularly large, the voltage detection cycle value can be 5V to 3.5V as one power frequency cycle. Figure 7, when the household appliance 500 is working and the current used by the household appliance 500 is large, the voltage detection cycle value may be 5V to 0V as one power frequency cycle. In this way, the voltage detection cycle value can reflect the working state of the household appliance 500, and the working state of the household appliance 500 is voice broadcasted by matching the voltage detection cycle value with a preset sound electrical signal. For example: the household appliance 500 is an electric rice cooker. If the voltage detection cycle value is maintained at 5V for each power frequency cycle, the sound electrical signal is matched according to the voltage detection cycle value, and the electroacoustic element 30 converts the sound electrical signal into a sound signal, and the sound signal may be "cooking is completed". If the voltage detection cycle value is 5V to 3.5V as one power frequency cycle, the sound electrical signal is matched according to the voltage detection cycle value, and the electroacoustic element 30 converts the sound electrical signal into a sound signal, and the sound signal may be "the rice cooker is keeping warm". If the voltage detection cycle value is 5V to 0V as one power frequency cycle, the sound electrical signal is matched according to the voltage detection cycle value, and the electroacoustic element 30 converts the sound electrical signal into a sound signal, and the sound signal may be "cooking".
