The specific embodiment

Referring to figs. 1 through Fig. 3 as can be seen, the utility model comprises: tooth bar, motor gear, motor, tooth bar 2 and gear 9 engagements, gear 9 is connected with 5 in motor, motor is fixedlyed connected with Connection Block 6, Connection Block is connected with window frame 10 by connecting hole 7, and tooth bar 2 is connected with movable window-frame 11 by connecting

hole

1,8; Described control circuit part, comprise: remote controller 12, receiver module 13, survey rain plate 3, decoding and control circuit 14, over-current detection circuit 20, circuit for controlling motor, rectification circuit 19, surveying rain plate 3 is connected with survey rain plate circuit 16, survey the rain plate and be arranged on side outside window, survey rain plate circuit and connect decoding and control circuit and circuit for controlling motor, circuit for controlling motor separated motor control circuit A and circuit for controlling motor B, circuit for controlling motor A is connected relay K 1 and relay K 2 respectively with circuit for controlling motor B, relay K 1 and relay K 2 are connected the two ends of the power supply input of direct current generator 19 respectively, circuit for controlling motor A is connected decoding and control circuit with circuit for controlling motor B, decoding and control circuit connect receiver module.Described relay K 1 is connected over-current detection circuit 20 with relay K 2.

With reference to Fig. 4 can, control circuit principle of the present utility model is as follows:

The 220V alternating current becomes 12V through transformer T1 transformation, after passing through rectifier diodes D7 rectification again, divide the output of two-way power supply through switching tube Q6 again: the one tunnel leads to the over-current detection circuit of being made up of Q7 and R18, provide power supply to survey rain circuit, direct current generator, DC motor control circuit, the effect of the over-current detection circuit of being made up of Q7 and R18 is: set the end on one side and meet when stifled when window forwards to, when circuital current increases to certain value, Q7 just quits work, and has realized that the end that window forwards any one side to promptly stops.C4, C5, C6 are filter capacitor, and C10 is an anti-interference capacitor, and D8 is a clamp diode.R17 is a current-limiting resistance, and R18 is a current-limiting resistance, and R12 is an overcurrent protection resistance, and R15, R16 are the insurance protective resistance.After indicator lamp D6 again through the voltage of U1 voltage-stabiliser tube output+5V, supplies the power supply of decoding and control circuit JP1 and receiver module, C11 is an anti-interference capacitor to another road power supply through the R12 step-down.

4 keys are arranged on the remote controller, be respectively and move to left, move to right, stop and locking key, when moving to left by remote controller respectively, receiver module receives the signal that transmits from remote controller when moving to right key, when being sent to decoding control circuit JP1 by receiver module, signal moves respectively from 10 through the JP1 inner decoding, 12 pin are to Q1, Q2 provides the conducting electric current, Q1, the Q2 conducting makes relay K 1 respectively, the K2 action, change the current direction of direct current generator by relay contact, left-hand rotation of realization direct current generator or right-hand rotation are controlled window and are moved to left or move to right, thereby realize opening or closing the purpose of window.C1 is a filter capacitor; C7 is an anti-interference capacitor; R3 is decoding and control circuit JP1 oscillation circuit resistance; R4, R5, R6 are current-limiting resistance; R7, R8 are respectively the conducting resistance of Q1, Q2, and Q1, Q2 are respectively the control valve of relay K 1, K2, and D1, D2 are anti-interference diode; C2, C3 are filter capacitor, and R1, R2 are respectively the relay coil protective resistance.

When pressing stop key, receiver module receives signal and is sent to decoding and control circuit JP1, JP1 moves by inner decoding, make 10,12 pin of JP1 be in off-state, thereby make Q1, Q2 can not get the conducting electric current, relay K 1, K2 can not get loop current and are failure to actuate, realize the direct current generator stall, thereby make window stop move left and right, meanwhile, circuit enters the rain state of surveying.

When rainy, the rainwater that is contained on the outdoor survey rain plate is formed with the resistance loop, provides loop current to Q5, Q4, relay, and direct current generator is rotated to the direction of setting, thereby realizes window when rainy day, can intelligence close window.C8, C9 are anti-interference capacitor, and R14, R10 are the Q5 biasing resistor, change the R10 resistance and just can change the sensitivity of surveying the rain circuit.R9 is the Q5 biasing resistor, and R13 is a current-limiting resistance.

When by the locking remote controller key, receiver module receives command signal and is sent to decoding and control circuit JP1, and JP1 moves by inner decoding, make the 13 pin conductings of JP1, and providing the conducting electric current to Q3, Q3 makes Q4 lose effective operating current and closes, and makes to survey the rain circuit and lose effect.This circuit function is: under outdoor rainy situation, also can manual remote control open or close window, D3, D4, D5 be anti-interference diode, and R11 is a current-limiting resistance.

Survey rain plate of the present utility model is connected to the outside of window by support 4, and support can be fixedlyed connected with Connection Block 6, also can be directly connected on the framework 10 of window or on the wall of the outside.
