Description

A kind of embedded single line delay small electronic switch device

Technical field

The utility model relates to electronic switch, in particular to a kind of embedded single line delay small electronic switch device.

Background technique

Currently, common electrical appliance switch such as wall type is a kind of, the need of specific occasion are had been unable to meet in many cases It asks, such as the workplace for the operation that needs to be delayed after the pass hull closures switch such as living room, bathroom, smoke evacuation exhaust, and some places It is that this function of discovery shortcoming delay operation needs to buy again if you need to add in life after switching installations assembly The relatively high electronic switch of price is reinstalled.

Utility model content

For the cost and practicability problem of the conversion of existing switch upgrade, the utility model provides a kind of embedded single line Be delayed small electronic switch device.

To achieve the above object, the concrete scheme of the utility model is as follows:

A kind of embedded single line is delayed small electronic switch device, including a PCB control panel, the PCB control panel include MCU control unit, the switch detection unit being electrically connected respectively with MCU control unit, silicon-controlled output unit, single line switch power supply End, delay adjustment signal element, the PCB control panel use single line connection type, and one end connects feeder ear, and other end connection is negative End is carried, the PCB control panel reaches stable state after powering in delay time, into the state of detection mechanical switch, when the One-time detection in the closure state, opens load to mechanical switch；It is described when detecting that mechanical switch is in an off state MCU control unit enters dormant state, waits mechanical switch closure triggering.

Preferably, the switching device time-delay closing time is adjustable, facilitates implantation mechanical switch.

Preferably, which further includes a small size shell, and the PCB control panel is cased.

Preferably, the shell includes face-piece and bottom case, and the enclosure volume is 45*22*17mm.

Using the technical solution of the utility model, have the advantages that

The utility model provides electronic delay function on not changing conventional mechanical switch structure basis for conventional mechanical switch Can, due to its advantage small in size, described device can easily be embedded into the switch of conventional wall mechanical switch one kind, complete The upgrading of electronic time-delay switch function.

Specific embodiment

Below in conjunction with the drawings and specific embodiments, the present invention will be further described.

Referring to figs. 1 to Fig. 4, the utility model provides a kind of embedded single line delay small electronic switch device, including one PCB control panel 2, the PCB control panel include MCU control unit 201, the switch inspection being electrically connected respectively with MCU control unit 201 It surveys unit 202, silicon-controlled output unit 203, single line and switchs feeder ear 204, delay adjustment signal element 205, the PCB control Plate 2 uses single line connection type, and one end connects feeder ear, and the other end connects load end, and the PCB control panel 2 is prolonging after powering on When the time in reach stable state, into detection mechanical switch 3 state, when detect for the first time mechanical switch 3 be in closure When state, load is opened；When detecting that mechanical switch 3 goes off state by unlatching, the silicon-controlled output end 203 is controlled Stop after load running to set delay time, then the MCU control unit 201 enters dormant state, and machinery is waited to open Close 3 closure triggerings.

The delay time can be continuously adjusted in 2 minutes to 40 minutes.

The switching device further includes a shell, and the PCB control panel is cased.

The shell includes face-piece 101 and bottom case 102, and the enclosure volume is 45*22*17mm.

In the utility model, electronics is provided for conventional mechanical switch on the basis of not changing conventional mechanical switch structure and is prolonged Shi Gongneng, due to the advantage of its compact, described device can easily be embedded into the switch of conventional wall mechanical switch one kind In, complete the upgrading of electronic time-delay switch function.It switching under open state, load end is normally-open, when detecting that switch disconnects, Load carries out time-delay closing according to the time-delay closing time set.

The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model, Under all utility models in the utility model are conceived, equivalent structure made based on the specification and figures of the utility model Transformation, or directly/be used in other related technical areas indirectly and be included in the protection scope of the utility model.
