Description

Technical Field

[0001] This utility model relates to the field of window opening machine technology, specifically to an electric screen window opening machine. Background Technology

[0002] An electric window opener is a device that automatically opens and closes windows, enabling automated control of window operation. Chain-type electric window openers are a type of electric window opener. Their core mechanism uses a metal chain as a transmission device to convert the rotational power of a motor into linear motion, thereby opening and closing the window. Currently, electric window openers can only open and close the window. For windows with screens, they cannot simultaneously open the window and close the screen. Closing the screen after opening the window is cumbersome, and closing the screen is even more difficult for windows located high up. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an electric screen window opener. This structure can simultaneously open the window and close the screen, improving convenience, and requires only one motor, thus reducing production costs.

[0004] An electric screen window opener includes a housing, within which a lead screw is rotatably mounted, and a motor is also housed within the housing. The motor is connected to the lead screw via a transmission mechanism, and a nut is fitted onto the lead screw.

[0005] A chain box is installed inside the outer casing, and a chain is slidably mounted inside the chain box. The chain passes through the chain box and the outer casing and connects to the window. A strip-shaped hole is opened on the chain box, and a nut passes through the strip-shaped hole to connect with the chain.

[0006] A fixing block is installed inside the outer casing. The lead screw passes through the fixing block, and a compression spring is connected to the fixing block. An annular groove is opened on the lead screw. When the lead nut moves to the annular groove, it contacts the compression spring.

[0007] Two screen window screws are rotatably mounted on the outer casing. The two screen window screws pass through the screen window slider and are threadedly connected to the screen window slider. The screen window slider is connected to the screen window. The screen window screws are connected to the screws through the transmission mechanism.

[0008] Preferably, the transmission mechanism includes a motor spur gear and a lead screw spur gear. The motor spur gear is connected to the motor output shaft, and the lead screw spur gear is fixedly sleeved on the lead screw. The motor spur gear meshes with the lead screw spur gear.

[0009] Preferably, the transmission mechanism two includes a bevel gear one and a bevel gear two, the bevel gear one being fixedly sleeved on the lead screw, the bevel gear two being fixedly sleeved on the screen window lead screw, and the bevel gear one meshing with the bevel gear two.

[0010] Preferably, the chain box is provided with a chain guide rail, and the chain is slidably disposed within the chain guide rail.

[0011] Preferably, two lead screw bearings are installed inside the housing, and the two ends of the lead screw are respectively connected to the inner walls of the two lead screw bearings.

[0012] Preferably, the outer casing is provided with a screen screw bearing, and the screen screw is connected to the inner wall of the screen screw bearing.

[0013] The beneficial effects of this utility model are as follows: In this technical solution, through the cooperation of various components, the window is initially closed, the screen is open, and the nut is a certain distance away from the annular groove. When the motor starts, it drives the lead screw to rotate, which in turn drives the nut to move linearly. The nut drives the chain, which in turn moves the window to open it, until the nut reaches the position of the annular groove and stops moving. During the rotation of the lead screw, the transmission mechanism two drives the two screen screws to rotate, which in turn drive the screen slider to move linearly. The screen slider then moves the screen to close it. This structure allows the window to open and the screen to close simultaneously, improving convenience, and requires only one motor, reducing production costs. Attached Figure Description
