Description

Technical Field

[0001] This utility model relates to the field of building door and window technology, and in particular to an electric opening and closing device for a louvered ventilation window. Background Technology

[0002] As a common building component, louvers are widely used in various places such as residences and offices because they can flexibly adjust indoor light and ventilation.

[0003] Traditional blinds are mostly operated manually, for example, by pulling a cord or turning a lever to control the angle of the slats. This manual operation is acceptable when the window is small or low, but it is very inconvenient, time-consuming and laborious for blinds that are installed high, large or numerous.

[0004] To address the inconvenience of manual operation, motorized louvers have emerged on the market. However, existing motorized solutions often suffer from structural deficiencies when it comes to synchronizing multiple louvers. Some solutions employ complex linkage mechanisms to transmit power; after prolonged use, wear can create gaps at the linkage connections, leading to uneven force transmission and deviations in the rotation angle of each louver, affecting overall aesthetics and airtightness. Other solutions, while using motor drives, have long transmission chains, resulting in significant accumulated errors and making it difficult to guarantee high synchronization and smooth operation of all louvers during opening and closing.

[0005] Therefore, this utility model proposes an electric opening and closing device for a louvered ventilation window to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of inconvenient opening and closing operation, poor synchronization and unstable operation when multiple louvers are linked in the existing technology, the present invention aims to provide an electric opening and closing device for louvered ventilation windows with improved structure that can effectively solve the above problems.

[0007] This utility model provides an electric opening and closing device for a louvered ventilation window, comprising: a frame, and a housing slidably connected to the frame via a slider, wherein the inner wall of the housing is provided with an installation groove, a plurality of swivel blades are rotatably connected to the housing, and one end of each swivel blade extends into the installation groove, and a gear is fixedly connected to one end of each swivel blade located in the installation groove; as well as a rack and an electric push rod.

[0008] The rack is slidably disposed within the mounting groove and meshes with all the gears.

[0009] Furthermore, the electric push rod is fixedly connected to the top of the housing, and the output end of the electric push rod is fixedly connected to the rack. The electric push rod outputs linear motion, directly driving the rack. The rack then distributes the power synchronously and evenly to each blade through precise meshing with each gear. The structure is direct and compact, with high transmission efficiency.

[0010] Preferably, the electric opening and closing device of the louvered ventilation window further includes an air pump, an air brush, and an air pipe; the air pump is fixedly connected to the frame, a sliding groove is provided on the outer side of the outer shell, the air brush is slidably connected in the sliding groove, and the two ends of the air pipe are respectively connected to the air pump and the air brush. This cleaning device is integrated into the window itself, solving the problem of difficulty in cleaning the louvered slats after dust accumulates.

[0011] Preferably, to facilitate manual operation of the cleaning device, the device further includes a handle fixedly connected to the air brush, allowing the user to easily move the air brush up and down by holding the handle.

[0012] Preferably, to further enhance the cleaning effect, the air brush is provided with bristles and several air holes, which are connected to the air pump via the air pipe. During cleaning, the bristles can physically remove attached dust, while the high-pressure airflow ejected from the air holes can blow away stubborn dust, achieving efficient cleaning through a combination of sweeping and blowing.

[0013] Preferably, to achieve the folding function of the window, the device includes two device units consisting of an outer shell and internal components, and the two device units are rotatably connected by hinges. This structure allows the window to be folded and stored when not in use, thereby maximizing the window space and providing an open view.

The cooperation between the latch and the positioning hole ensures the stability of the folded state.

[0015] Preferably, to enhance locking reliability and prevent accidental operation, the device further includes a retaining sleeve fixed to the handle, the retaining sleeve having a corner groove for limiting the sliding stroke of the pin. This corner groove structure can limit and lock the extended or retracted state of the pin, improving safety.

[0016] Preferably, as a specific implementation of the sliding connection, the slider is fixedly connected to the upper and lower end faces of one side of the outer shell, and the frame is provided with guide rails that cooperate with the slider. The sliding cooperation between the slider and the guide rails ensures the smooth and stable translation of the outer shell on the frame, providing a reliable motion basis for the folding action.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Example: Please refer to Figures 1 to 5 This utility model provides an electric opening and closing device for a louvered ventilation window, which aims to solve the problems of inconvenient operation of louvered windows and poor synchronization of multiple swing blades in the prior art.

[0025] like Figure 1 As shown, the electric opening and closing device of the louvered ventilation window includes a frame 1 and a shell 2 slidably connected to the frame 1; the frame 1 is used to fix the entire device at the window opening position on the wall as the overall load-bearing foundation; the shell 2 is the main body of the louvered window, and through sliding cooperation with the frame 1, the window can be moved horizontally.

[0026] Reference Figure 1 and Figure 2 The inner wall of the outer casing 2 is provided with an installation groove, and several oscillating blades 3 are rotatably connected to the outer casing 2. One end of each oscillating blade 3 extends into this installation groove. The oscillating blades 3 are used to adjust light and ventilation.

[0027] Each pendulum 3 is fixedly connected to a gear 4 at one end within the mounting groove. The gear 4 is used to convert linear motion into rotation of the pendulum 3. The rack 5 is slidably disposed within the mounting groove and meshes with all the gears 4. The rack 5 is used to transmit linear power and drive all the gears 4 to rotate synchronously.

[0028] The electric push rod 6 is fixedly connected to the top of the housing 2, and the output end of the electric push rod 6 is fixedly connected to the rack 5. The electric push rod 6 is used to provide the power source for driving the rack 5 to reciprocate. When the output end of the electric push rod 6 extends, it drives the rack 5 to slide downward. The rack 5 drives all the gears 4 to rotate clockwise synchronously through meshing, thereby driving all the oscillating blades 3 to open synchronously. When the output end of the electric push rod 6 retracts, it drives the rack 5 to slide upward. The rack 5 drives all the gears 4 to rotate counterclockwise synchronously, thereby driving all the oscillating blades 3 to close synchronously.

[0029] To further enhance the practicality of the blinds, this embodiment also provides an active cleaning device; please refer to it carefully. Figure 1 , Figure 3 and Figure 4 The structure of this cleaning device will now be described in detail.

[0030] The cleaning device includes an air pump 10, an air brush 7, and an air pipe 9; the air pump 10 is fixedly connected to the frame 1 and is used to generate high-pressure airflow; a sliding groove is provided on the outer side of the housing 2, and the air brush 7 is slidably connected in the sliding groove for reciprocating cleaning on the surface of the swing blade 3.

[0031] The air brush 7 is equipped with bristles and several air holes. The bristles are used to physically remove the attached dust, and the air holes are used to spray high-pressure airflow to blow away the dust. The two ends of the air pipe 9 are connected to the air pump 10 and the air brush 7 respectively, forming a complete airflow delivery channel, which accurately guides the high-pressure airflow generated by the air pump 10 to the air holes of the air brush 7.

[0032] To facilitate manual operation, a handle 8 is fixedly connected to the air brush 7. When cleaning is required, the user can hold the handle 8 and move the air brush 7 up and down along the slide groove on the outer casing 2. At the same time, the air pump 10 is activated. The bristles of the air brush 7 and the airflow ejected from the air hole work together to efficiently clean the surface of all the blades 3.

[0033] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, to achieve the folding function of the blinds and obtain maximum light and view, please refer to... Figure 1 and Figure 5 The device includes two device units consisting of an outer shell 2 and internal components, and the two device units are rotatably connected by a hinge, which allows the two device units to move closer to each other or unfold.

[0034] In order to lock the two device units in the folded state, the device also includes a handle 11 and a pin 12; the handle 11 is rotatably connected between the two housings 2 to provide a point of force for operation; the pin 12 is slidably inserted into the handle 11, and the end of the pin 12 can be selectively inserted into a positioning hole opened on the frame 1. The reliable locking of the folded state is achieved through the cooperation of the pin 12 and the positioning hole.

[0035] As a further optimization of the locking mechanism, in order to prevent the pin 12 from accidentally dislodging or retracting, the device also includes a retainer 13; the retainer 13 is fixed to the handle 11, and the retainer 13 has a corner groove for limiting the sliding stroke of the pin 12; the lever provided on the pin 12 passes through this corner groove, and by rotating the lever and engaging it in a specific position in the corner groove, the extended or retracted state of the pin 12 can be double-locked.

[0036] As a specific implementation of the sliding mechanism, the slider 14 is fixedly connected to the upper and lower end faces of one side of the outer shell 2, and a guide rail is provided on the frame 1 to cooperate with the slider 14; the outer shell 2 moves smoothly on the frame 1 through the sliding cooperation between the slider 14 and the guide rail, providing the necessary translation space for the folding action.

[0037] Working principle: Electric opening and closing process: When it is necessary to adjust the angle of the swing blade 3, the electric push rod 6 is activated. The output end of the electric push rod 6 extends or retracts, driving the rack 5, which is fixedly connected to it, to perform linear reciprocating motion in the mounting groove. Since the rack 5 meshes with the gear 4 fixed on each swing blade 3 at the same time, the linear motion of the rack 5 is converted into the synchronous, same-direction, and same-angle rotation of all gears 4. The rotation of the gears 4 then drives all swing blades 3 to rotate synchronously, thereby achieving precise and stable adjustment of indoor light and ventilation.

[0038] Manual cleaning process: When it is necessary to clean the blade 3, the user holds the handle 8 fixed on the air brush 7 and starts the air pump 10 fixed on the frame 1; the high-pressure airflow generated by the air pump 10 is delivered to the air brush 7 through the air pipe 9 and sprayed out from the air hole on it; the user drives the air brush 7 to slide up and down along the slide groove on the outer shell 2, the bristles on the air brush 7 physically sweep the surface of the blade 3, and at the same time the high-pressure airflow blows away the attached dust, achieving a cleaning effect of combined sweeping and blowing.

[0039] Folding and locking process: When the window needs to be fully opened, first operate the latch 12 by using the handle 11 to disengage it from the positioning hole of the frame 1 and unlock it; then, hold the outer shell 2 and let it slide to one side on the frame 1 through the cooperation of the slider 14 and the guide rail; when the two device units are moved close enough, use the rotation function of the hinge to fold the two device units together, thereby fully opening the window space; conversely, after opening the window, slide it to the closed position and then operate the latch 12 to insert it into the positioning hole to complete the locking.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
