Abstract
The invention discloses an electric awning and a rainwater detecting sensor. The electric awning comprises the rainwater detecting sensor which is in control connection with a control circuit board of the electric awning, wherein the rainwater detecting sensor is non-contact rainwater detecting sensor. Because the electric awning uses the non-contact rainwater detecting sensor, rainwater can not directly contact the non-contact rainwater detecting sensor, and the service life of the non-contact rainwater detecting sensor is prolonged; and misoperation can not happen due to the influence of dew and so on. The rainwater detecting sensor comprises an oscillatory excitation circuit, an emission electrode driven by the oscillatory excitation circuit, a collecting electrode corresponding to the emission electrode, and a testing circuit which is connected with the collecting electrode for testing the change of an electric field, wherein the emission electrode is parallelly arranged with the collecting electrode to form the electric field. The sensing part of the rainwater detecting sensor does not need contacting the rainwater directly to sense whether it is rainy, along with good effect.
Description
Technical field
The present invention relates to the motor-driven technical field, more particularly, relate to a kind of can raining and launch automatically or closed electronic sun is fluffy and the rain detecting sensor that uses according to whether.
Background technology
Existing electronic sun is fluffy can to drive positive fluffy expansion and closure automatically by motor.In order to allow the fluffy control that does not need the people of sun and to launch automatically or closed in the rainy day, people have just designed can be by whether the rainy electronic sun of controlling is fluffy, respond to and whether rain by in electronic sun is fluffy, increasing rain detecting sensor, thus fluffy expansion or the closure of control sun automatically.
Whether existing rain detecting sensor all is a contact, promptly all is that the sensing part with rain detecting sensor is arranged on the open-air position that can contact with rainwater, by contacting with the direct of rainwater, detect and rain.The patent application that the applicant submitted to State Intellectual Property Office on January 15th, 2008: a kind of apparatus for controlling of lifting of sunshade (application number: the rain detecting sensor that discloses a kind of contact 200820091631.9), its structure as shown in Figures 2 and 3, described rain detecting sensor 5 is provided with two two parallel wires 6 of connecting circuit positive and negative terminal respectively, on each bar lead, be respectively equipped with the conductive rain induction line segment 7 that stretches to another lead direction, each bar lead and on rain induction line segment and another lead and on rain respond to line segment and be not connected.Parallel to each other between the described rain induction line segment 7, rain induction line segment 7 is perpendicular to two parallel leads 6.Two adjacent rain that rain induction line segment 7 on each bar lead all is arranged on another lead 6 are responded between the line segments 7.This structure at the rainwater unconnected rain induction line segment of flowing through, because rainwater itself has electric action, just makes disconnected two parallel wire conductings, sends to control circuit thereby produce induced signal.
Can be also just because of rainwater unconnected rain induction line segment of need flowing through, respond to line segment with rain and directly contact just can detect and whether rain, this is easy to regard to the rain detecting sensor that causes contact because get rusty or the corrosion of rainwater and wearing out.And because whether the rain detecting sensor of contact detects rainy by unconnected rain induction line segment on two leads, if this just makes when having dewdrop to condense on adjacent rain induction line segment, will make disconnected two parallel wire conductings, thereby produce induced signal and send to control circuit, rain detecting sensor can be thought the current rainy state that also is in by mistake, causes flase drop to be surveyed.
