Embodiment 2

[0077] Embodiment 2 is an independent power switch, which can be installed in a living room or an office to control electricity consumption. Its structure is similar to that of Embodiment 1. The control unit includes four control devices such as a start control button, a continuation control button, a timer off button, and a duration adjustment knob, as well as a remote control device. Its timing device adopts an electronic timer with multiple contacts, the built-in duration t is set at 2 to 3 hours, and the time for sending an alarm signal in advance is set at about 10 minutes. Its power switch adopts a normally closed relay, the input end of the relay is connected with the timing device, and the output end is connected with the power supply. Press the start button of the relay to turn on the power and trigger the timer to start counting. Its alarm unit adopts sound / light alarm, and its built-in alarm program, once triggered, it will send out an alarm signal according to thi...

Embodiment 3

[0083] Embodiment 3 The power switch device is installed as a device in electrical appliances with high power consumption or high risk such as air conditioners or electric blankets. When the utility model is used as a built-in switch of the air conditioner, the existing remote controller of the air conditioner can be slightly improved by adding a continuous time control key.

Abstract

The invention relates to a power switch device which comprises a control unit, a timing device, an alarm unit and a normally closed type relay. The control unit is used for controlling the timing device, the alarm unit and the normally closed type relay through at least two control devices; the timing device is used for triggering the alarm unit to give alarm signals and also used for triggering to disconnect a power switch; the alarm unit is used for giving alarm signals or stopping giving alarm signals through an internal sound / light alarm device; and the normally closed type relay is used for connecting or disconnecting a power supply. The power switch device adopts a design concept different from that of a common timing switch, and can overcome faults caused by inertia or forgetting of common people, a power customer can receive alarm signals when the operation time of power switch device is about to a preset duration, the power customer can judge whether to continue to use electricity according to current conditions, and presetting is not required.

Description

technical field [0001] The invention relates to the technical field of power switches, in particular to a power switch with automatic timing and early warning functions. Background technique [0002] With the advancement of science and technology, various household and office appliances continue to appear. In addition to various lighting fixtures, televisions, air conditioners, electric fans, electric rice cookers, electric blankets and other electrical appliances have entered thousands of households. The application of these electrical appliances has brought great convenience to people's work and life, but also brought a problem, that is, the probability of forgetting to cut off the power supply has greatly increased. This will not only lead to unnecessary waste of power resources, but also a great fire hazard. [0003] In daily electricity consumption, there is another problem, that is, the waste of electricity caused by not pulling out the power plug. Relevant data sho...
