Description

Timing Automatic Window Opener

technical field

The invention relates to a window opening machine, in particular to a timing automatic window opening machine.

Background technique

There are many kinds of window opening machines in the existing market, and their application ranges and targeting directions are also different. The photovoltaic power window opener disclosed in Chinese patent CN201520232722 belongs to the technical field of electric skylights. The solar intelligent window opener disclosed in Chinese patent CN201220150517.5 uses monocrystalline silicon solar panels to provide energy for the electric window opener, and uses a high-precision photoelectric tracker to automatically control the solar panel to always be perpendicular to the sun, which requires a large cost , and only applicable to the opening and ventilation of skylights and top-hung windows. The Bluetooth-based wireless remote control window controller system disclosed in Chinese patent CN201620031982.5 is suitable for smart home environments and cannot be applied to push-pull windows. The above three window opening machines are not practical for ordinary urban users.

With the wide application of air conditioners in hot summer, windows are opened regularly to allow air to circulate, making the appearance of automatic window openers a healthy and environmentally friendly way of life. In this context, a timing automatic window opener that is simple in structure, low in cost, long in service life, convenient and reliable, and applicable to a wide range of ordinary families is particularly needed.

Contents of the invention

The purpose of the present invention is to provide a timing automatic window opener to solve the problems of indoor air not circulating after the air conditioner is turned off regularly in summer.

The present invention is provided with left plate, right plate, bottom plate, motor, large gear, pinion, gear shaft, cam, block, ratchet, ratchet shaft, rope wheel, stay wire and coil spring; Said left plate, right plate and bottom plate As the base of the timing automatic window opening machine, the small gear is fixed on the motor shaft, the small gear meshes with the large gear, the large gear is coaxial with the cam and fixed on the gear shaft, the block contacts the cam, and the block controls the braking of the ratchet , the ratchet, the rope wheel and the coil spring are coaxial and fixed on the ratchet shaft, one end of the coil spring is fixed on the ratchet shaft, and the other end of the coil spring is fixed on the left plate; the gear shaft and the ratchet shaft are placed parallel to the base plate.

The invention can be used for timing opening of push-pull windows, has simple structure and is easy to implement. When in use, use the timer switch socket to supply power to the motor. Hang one end of the stay wire with a fixed hook on the corresponding hook of the window, and wrap the other end around the rope wheel. When people need to turn on the air conditioner indoors and manually close the window, the stay wire will move with the window to drive the rope wheel to rotate. The rope wheel is fixed on the ratchet shaft, and when the ratchet shaft rotates, the coil spring will be tightened along with the rotation of the shaft, and the ratchet will also rotate counterclockwise. When the window is fully closed, the sheave will no longer rotate and the coil spring will have a tendency to relax. At this time, the block will block the ratchet, so that the ratchet cannot rotate, thereby hindering the relaxation of the coil spring and keeping the coil spring in a tensioned state. The time when the air conditioner is set to turn off at regular intervals is the time when the timer is powered on. When the air conditioner is turned off, the timer socket is energized, the motor rotates, the gear and the motor rotate coaxially, and the appropriate rotation speed is adjusted through the meshing of the large and small gears, so that the cam rotates with the gear at a certain speed, and the block rotates with the cam. activities, the ratchet can no longer be blocked, the tendency of the coil spring to relax makes the ratchet rotate clockwise, the ratchet shaft also rotates with the ratchet, and the window opens.
