Description

Technical Field

[0001] The present invention relates to the technical field of intelligent switches, and in particular to an intelligent switch based on micro-motor action. Background Art

[0002] In the prior art, there are several switches as follows:

[0003] Manual switches and switches that use relays or transistors to complete on-off: When used in intelligent applications, they have low intelligence, coil power consumption or temperature rise caused by transistor operation, manual / remote switching cannot be done freely, the maximum current value is relatively small (16A), the noise is loud when switching, and there are contact sparks. They are often used in lighting and fans;

[0004] Rocker switch: It is a common manual switch that is turned on and off by manual pressing. It is a mechanical switch in physical position and is a single-pole single-throw type, which cannot realize intelligent remote control.

[0005] Tactile switch: Most of them use circuit-driven transistors or relays to switch the circuit on and off. They consume a lot of power and are prone to temperature rise. However, they cannot be used manually when the switch fails.

[0006] Single-pole double-throw push switch and thyristor or relay structure touch switch: manual and remote control are realized based on the dual control principle of corridor lights, but there are phenomena such as relay coil being energized and temperature rising when remote control is turned off;

[0007] Most existing fan coil thermostats use three relays to switch three-speed on and off, and use one or two relays to control one electric valve (two-pipe control) or two electric valves (four-pipe control) on and off. When the fan coil power is greater than 200W, most existing thermostats are easy to be damaged, and there are many wirings between the thermostat and the coil.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] At present, switches in the prior art have electric shock sparks, poor intelligence, and temperature rise and heat generation. Based on this, an intelligent switch based on the action of a micromotor 102 provided in an embodiment of the present invention can alleviate the technical problems of switches in the prior art having electric shock sparks, poor intelligence, and temperature rise and heat generation.

[0037] To facilitate understanding of this embodiment, firstly, a smart switch based on the action of the micro motor 102 disclosed in the embodiment of the present invention is introduced in detail.

[0038] Combination Figure 1 as well as Figure 2 , the present invention provides an intelligent switch based on the action of a micro motor 102, comprising: a power device, a microcontroller, a transmission device, a switch action device 104 and a contact 302;

[0058] Furthermore, the number of grooves on one of the arc surfaces is 4, and the surface of this arc does not contact the contact point 302, and the surfaces of the other two arcs contact different contact points 302 during rotation;

[0059] Preferably, it also includes a monitoring device, which includes a temperature monitoring device and a current monitoring device.

[0060] Furthermore, the switch provided by the present invention can also detect the amount of electricity. Specifically, in order to realize temperature monitoring, a temperature sensor needs to be installed, and in order to monitor the current, an ammeter is required.
