Abstract
The utility model relates to socket with touch-sensitive warning device belonging to the field of electric household appliance manufacturing, which comprises a shell, a warning device, a touch-sensitive electrode slice and a control circuit. Wherein, the touch-sensitive electrode slide is arranged on the shell. The warning device is arranged on the side face of the shell and the control circuit is positioned in the shell. In addition, the warning device and touch-sensitive electrode slice are connected with the control circuit. The control circuit is composed of a power source circuit, a touch-sensitive delay circuit, a controllable silicon switch circuit and a negative resistance oscillator circuit, all of which are electrically connected. The warning device is provided with a piezoelectric ceramic sheet and a low-power circuit. The power source circuit can provide 12V DC voltage. As human body touches the electrode slice, the touch-sensitive switch opens the controllable silicon switch, thus enabling the negative oscillator to oscillate and the warning device to emit warning sound. Therefore, the utility model prevents accidents arising from carelessly touching the socket and has advantages of rational structure and great safety.
Description
Technical field
The utility model relates to a kind of socket, specifically a kind of touch mode alarm socket.
Background technology
In the life of reality, usually cause electric shock owing to the fond of play of child or owing to people touch socket accidentally, cause various personal injuries or other accidents, bring a lot of inconvenience for people's daily life.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of anti-electric alarm, touch mode alarm socket rational in infrastructure, easy to use.
The utility model is achieved through the following technical solutions: a kind of touch mode alarm socket, form by housing, alarm, touch electrode sheet, control circuit, the housing upper surface is provided with the touch electrode sheet, alarm is located at the housing side, control circuit is connected in the housing, and alarm, touch electrode sheet are electrically connected with control circuit.
Described control circuit is made up of power circuit, touch delay circuit, reverse-blocking tetrode thyristor circuit and negative resistance oscillation circuit, and each element is electrically connected.
The utility model alarm is a piezoelectric ceramic piece, and circuit power consumption is very little, and power circuit provides the direct voltage of 12V.When human body touch arrives electrode slice, touch circuit and open reverse-blocking tetrode thyristor, make the negative resistance oscillator starting of oscillation of its control, alarm just sends alarm sound.When people use socket so afterwards, just can avoid touching socket accidentally and the accident that causes, have advantages such as rational in infrastructure, safe in utilization.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model circuit diagram.
Wherein, 1, housing, 2, alarm, 3, the touch electrode sheet, 4, power circuit, 5, touch delay circuit, 6, the reverse-blocking tetrode thyristor circuit, 7, negative resistance oscillation circuit.
Embodiment
Embodiment: structure as shown in Figure 1 and Figure 2, this socket is made up of housing 1, alarm 2, touch electrode sheet 3, control circuit, housing 1 upper surface is provided with touch electrode sheet 3, alarm 2 is located at housing 1 side, control circuit is located in the housing 1, and alarm 2, touch electrode sheet 3 are electrically connected with control circuit.Described control circuit is made up of power circuit 4, touch delay circuit 5, reverse-blocking tetrode thyristor circuit 6 and negative resistance oscillation circuit 7, and each element is electrically connected.When staff touches electrode slice 3, the resistance of human body leakage current through touching circuit 5 injects the emitter junction of triode, make the triode conducting, 12V direct voltage on power circuit 4 electric capacity provides the forward gate current to controllable silicon V S gate pole, make V S open-minded rapidly, the oscillating capacitance two ends can obtain the high direct voltage about 300V, make negative resistance oscillator 5 starting of oscillation at once, and alarm 2 just sends loud chimes of doom.After staff left electrode slice 3, the triode that touches circuit 5 recovered cut-off state rapidly, provided the forward gate current but the electric energy that this moment, ghyristor circuit 6 electric capacity stored continues as V S, so reverse-blocking tetrode thyristor can not turn-off immediately, circuit is still reported to the police.Put until capacitance charge, when the alternating current zero passage, turn-offed.If touch electrode slice 3 once more, then circuit can be reported to the police again at once.
Claims (2)
1, a kind of touch mode alarm socket is characterized in that, is made up of housing, alarm, touch electrode sheet, control circuit, the housing upper surface is provided with the touch electrode sheet, alarm is located at the side of housing, and control circuit is located in the housing, and alarm, touch electrode sheet are electrically connected with control circuit.
