Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of the present application, "a plurality" means two or more unless specifically defined otherwise.

Referring to fig. 1, the present embodiment provides a linkage apparatus including a linkage signal transmitter 100, a consumer 200, and a receiver 300. The electric equipment 200 and the linkage signal transmitter 100 are connected and then connected to an alternating current power supply together. The linked signal transmitter 100 is used for sending a signal to control the receiving device 300, so that the receiving device 300 can work synchronously with the electric device 200.

For convenience of understanding, in the present embodiment, an electric drill is used as the electric power using apparatus 200, and a water supply apparatus is used as the receiving apparatus 300.

Referring to fig. 2, the linked signal transmitter 100 of the present embodiment includes an ac power input terminal 1, a power step-down circuit 2, and a signal transmitting circuit 3.

The ac power supply inlet 1 may also be referred to as an ac power supply inlet (Port). The ac power input terminal 1 is connected to the electric device 200 to supply ac power to the power step-down circuit 2. Specifically, the ac power supply inlet 1 is connected to an internal circuit of the electric device 200; when the electric device 200 is powered on by ac power, the ac power inlet 1 is also powered on by ac power, so as to provide ac power for the power step-down circuit 2. For example, referring to fig. 1, an ac power inlet 1 is connected to one end of a switch 201 of an electric device 200; the other end of the switch 201 is connected to an alternating current power supply; when the switch 201 of the electric equipment 200 is closed, the electric equipment 200 is connected with an alternating current power supply, and the alternating current power supply access end 1 is also connected with the alternating current power supply; when the switch 201 of the electric equipment 200 is turned off, the electric equipment 200 is disconnected from the ac power supply, and the ac power supply inlet 1 is also disconnected from the ac power supply.

The power supply voltage reduction circuit 2 is an alternating current-direct current conversion circuit and can convert alternating current into direct current so as to supply power to the signal transmitting circuit 3.

The signal transmitting circuit 3 is for continuously sending out a signal immediately while being powered on and for stopping sending out a signal immediately while being powered off. Specifically, the signal transmitting circuit 3 transmits a designated signal to the receiving device 300 after being powered on, so that the receiving device 300 continuously operates; when the signal transmitting circuit 3 is powered off, the transmission of the designation signal to the receiving apparatus 300 is stopped, and the receiving apparatus 300 stops operating.

According to the above, the ac power input terminal 1 of the linked signal transmitter 100 is connected to the electric device 200, so as to be connected to an ac power source, and further, the ac power source is provided to the power step-down circuit 2. The power supply step-down circuit 2 converts alternating current obtained from the alternating current power supply inlet 1 into direct current, thereby supplying power to the signal transmitting circuit 3. The signal transmitting circuit 3 continuously transmits signals to the outside immediately after being powered on, specifically continuously transmits signals to the receiving device 300, so that the receiving device 300 and the electric equipment 200 work synchronously; after the ac power supply access terminal 1 is disconnected from the ac power supply, the signal transmitting circuit 3 immediately stops sending a signal to the outside, specifically, stops sending a signal to the receiving device 300, so that the receiving device 300 stops working; that is, the receiving apparatus 300 stops operating when it does not receive the signal transmitted by the signal transmitting circuit 3. Therefore, the receiving device 300 can be accurately linked with the electric equipment 200, and the use is convenient. For example, when the electric drill starts to work, the water supply equipment also supplies water to the electric drill synchronously; when the electric drill stops working, the water supply equipment also stops supplying water to the electric drill immediately.

The linkage signal transmitter 100 is connected with the electric equipment 200 in a plugging manner; when in use, the linkage signal emitter 100 is inserted into the electric equipment 200; when the linkage signal emitter 100 is not needed to be used, the linkage signal emitter 100 is pulled out of the electric equipment 200; thus, it is convenient to use.

The signal transmission circuit 3 of the present embodiment includes a signal transmission chip U2 and peripheral circuits. The signal transmitting chip U2 is a transmitting chip in the prior art. The peripheral circuit is connected to the periphery of the signal transmitting chip U2 to ensure the normal operation of the signal transmitting chip U2.

Referring to fig. 2, the peripheral circuit includes a reference signal generator Y1. Both ends of the reference signal generator Y1 are connected to the pin 1 and the pin 8 of the signal transmitting chip U2, respectively, to supply a reference signal to the signal transmitting chip U2, so that the signal transmitting chip U2 can generate various accurate signals. In the present embodiment, the reference signal generator Y1 is a quartz crystal oscillator; in other embodiments, other oscillators may be used as the reference signal generator Y1, as desired.

The peripheral circuit further includes an antenna T1, a first inductor L1, a first capacitor C1, and a second inductor L2. Two ends of the first inductor L1 are connected to the pin 2 and the pin 4 of the signal transmitting chip U2, respectively. One end of the first capacitor C1 connected in series with the second inductor L2 is connected to the pin 4 of the signal transmitting chip U2, and the other end is connected to the antenna T1. The antenna T1 is used to transmit signals, such as to the receiving device 300.

Pin 3 of the signal transmitting chip U2 is connected to ground GND. The pin 1 and the pin 8 of the signal transmitting chip U2 are also connected to the ground GND through a seventh capacitor C7 and an eighth capacitor C8, respectively.

Referring to fig. 2, the power step-down circuit 2 includes an ac-dc conversion sub-circuit 21, a zener diode ZD1, an energy storage capacitor C0, and a second capacitor C2. The ac-dc conversion sub-circuit 21 may convert an ac voltage into a dc voltage. The zener diode ZD1, the storage capacitor C0, and the second capacitor C2 are connected in parallel in this order to the dc output side 211 of the ac-dc converter sub-circuit 21. Specifically, the dc output side 211 has two output terminals, i.e., an output terminal V + and an output terminal V-; the output terminal V-is connected to the ground GND; both ends of the zener diode ZD1, both ends of the storage capacitor C0, and both ends of the second capacitor C2 are connected to the output terminal V + and the output terminal V-, respectively. The output terminal V + is connected to pin 2 of the signal transmitting chip U2, thereby supplying power to the signal transmitting chip U2.

The number of terminals of the ac power supply inlet 1 is two, and the terminals are a terminal ACN and a terminal ACL. An input-side inductor L0 and a first resistor R1 are connected in series to one end of the ac input side 212 of the ac-dc converter sub-circuit 21. One end of the first resistor R1 serves as a terminal ACN of the ac power supply inlet 1. The other end of the ac input side 212 of the ac-dc conversion sub-circuit 21 is connected in series to a step-down capacitor CX. The two ends of the voltage-reducing capacitor CX are connected in parallel with a second resistor R2. One end of the step-down capacitor CX connected in parallel to the second resistor R2 serves as a terminal ACL of the ac power supply input terminal 1. The voltage reduction capacitor CX plays a role in reducing the voltage of the alternating current power supply; that is, the voltage-reducing capacitor CX and the second resistor R2 serve as a voltage-reducing sub-circuit of the power voltage-reducing circuit 2, or the power voltage-reducing circuit 2 further includes a voltage-reducing sub-circuit. Of course, the voltage step-down sub-circuit may also be a transformer circuit.

After the ac power supply is connected to the ac power supply connection terminal 1, the ac-dc conversion sub-circuit 21 immediately operates and supplies power to the signal transmitting chip U2, the signal transmitting chip U2 transmits a signal through the antenna T1, and the receiving device 300 receives the signal and starts operating. After the ac power inlet 1 is disconnected from the ac power, the signal transmitting chip U2 stops transmitting the signal, and the receiving device 300 also stops working.

The embodiment of the application can realize stable and accurate linkage of two or more devices, is convenient to use, and has a simple structure and low cost.
