[0049] Venetian blinds allow for control of light exposure by adjusting the angle of the slats, providing good ventilation. However, in related technologies, the connectors between the slats and the drive structure of automatically opening and closing venetian blinds are prone to aging and damage after long-term use, affecting the service life of the automatic opening and closing venetian blinds.
[0050] Based on the above problems, this utility model proposes an automatic opening and closing louver 100, which aims to solve the problem that the connector 40 connecting the blade 30 and the drive structure 20 is prone to aging and damage after long-term use, so as to extend the service life of the automatic opening and closing louver 100.
[0051] Please see Figures 1 to 5 In one embodiment of this utility model, the automatic opening and closing louver 100 includes a mounting base 10, a drive structure 20, and blades 30; the drive structure 20 is disposed on the mounting base 10; the blades 30 are disposed on the mounting base 10 and are connected to the drive structure 20 in a transmission manner, and the drive structure 20 drives the blades 30 to rotate so that the blades 30 switch between an open state and a closed state; wherein, the blades 30 are connected to the drive structure 20 in a transmission manner through a connector 40, and the connector 40 is a wear-resistant part.
[0052] It is understood that the technical solution of this utility model uses a wear-resistant part as the connector 40. Because the wear-resistant part has good wear resistance, the blade 30 is connected to the drive structure 20 through the wear-resistant connector 40. In this way, when the blade 30 is driven by the drive structure 20 to switch between the open and closed states through the connector 40, the connector 40 connecting the blade 30 and the drive structure 20 will not easily age and be damaged. This solves the problem that the connector 40 connecting the blade 30 and the drive structure 20 is prone to aging and damage after long-term use, thereby extending the service life of the automatic opening and closing louver 100.
[0053] In this embodiment, the mounting base 10 is used to install and fix the drive structure 20, blades 30, and other structures, and the automatic opening and closing louver 100 is installed on a wall or other carrier via the mounting base 10. Optionally, the mounting base 10 may include a blade mounting base 11 and a motor mounting base 12. The blade mounting base 11 is also called the window frame, and the blades 30 are mounted on the blade mounting base 11 to open or close the opening of the window frame. The motor mounting base 12 can be fixed to the blade mounting base 11 by screws or other structural components, and the drive structure 20 can also be fixed to the motor mounting base 12 by screws or other structural components. When the drive structure 20 drives the blades 30 to rotate to the open state, the blades 30 open the opening of the window frame; when the drive structure 20 drives the blades 30 to rotate to the closed state, the blades 30 close the opening of the window frame, thereby realizing the automatic opening and closing of the louver.
[0054] The blade 30 is connected to the drive structure 20 via the connector 40. It can be understood that when the drive structure 20 is working, it can drive the blade 30 to rotate via the connector 40.
[0055] In practical applications, the drive structure 20 can be a component that combines a motor and a transmission rod. In this case, the transmission rod is connected to the output shaft of the motor, and the transmission rod is connected to the blade 30 via a connector 40. When the motor operates, it drives the transmission rod to rotate, which in turn drives the connector 40 to rotate, and consequently, the blade 30 rotates via the connector 40. Alternatively, the drive structure 20 can also be a component that combines a motor and a rack and pinion. In this case, the rack meshes with the output shaft of the motor, and the rack meshes with the gear. The gear is connected to the blade 30 via the connector 40. When the motor operates, it drives the rack to move, which in turn drives the gear to rotate. The rotation of the gear drives the connector 40 to rotate, and consequently, the blade 30 rotates via the connector 40. Of course, the drive structure 20 can also be any other structure, as long as it can drive the blade 30 to rotate via the connector 40 when the drive structure 20 is in operation.
[0056] In practical applications, the connector 40 can be made of metal, nylon reinforced with glass fiber, or other wear-resistant materials. For example, metal parts can be made of stainless steel, aluminum alloy, cast iron, high manganese steel, alloy steel, etc. All of these structural parts are more resistant to aging and wear than plastic parts.
[0057] Please see Figures 1 to 3 In one embodiment of this utility model, the connector 40 can be a stainless steel component.
[0058] This design, using stainless steel components as connectors 40, offers advantages such as high corrosion resistance, strength and hardness, high temperature resistance, and aging resistance. It also has good plasticity and weldability, allowing it to be formed through cold working, hot working, and welding processes. Furthermore, it is more aesthetically pleasing and does not contain harmful heavy metal elements, making it more environmentally friendly and healthier.
[0059] Please see Figures 1 to 3 In one embodiment of the present invention, the drive structure 20 includes a drive motor 21, a first swing arm 22, and a connecting rod 23; the drive motor 21 is mounted on the mounting base 10; one end of the first swing arm 22 is connected to the output shaft of the drive motor 21; the other end of the first swing arm 22 is rotatably connected to the connecting rod 23 through a connector 40; the blade 30 is rotatably connected to the connecting rod 23 through the connector 40.
[0060] With this configuration, the drive motor 21 can drive the first swing arm 22 to swing. The swing of the first swing arm 22, through one of the connecting parts 40, drives the connecting rod 23 to move. The movement of the connecting rod 23, in turn, drives the other connecting part 40 to rotate, which in turn drives the blades 30 to rotate, allowing the blades 30 to smoothly switch between open and closed states. Therefore, this embodiment, through the cooperation of the drive motor 21, the first swing arm 22, the connecting rod 23, and the connecting parts 40, can more smoothly drive the blades 30 to rotate, thus precisely achieving the automatic opening and closing of the venetian blinds.
[0061] In some embodiments, the drive motor 21 can be fixed to the motor mounting base 12 by screws or other structural components, and one end of the first swing arm 22 can be sleeved on the output shaft of the drive motor 21 so that the first swing arm 22 can be driven to swing through the output shaft of the drive motor 21.
[0062] Please see Figures 1 to 3 In one embodiment of this utility model, the connector 40 connecting the first swing arm 22 and the connecting rod 23 is defined as the first connector 41. One end of the first connector 41 is rotatably connected to the first swing arm 22, and the other end of the first connector 41 is embedded in the connecting rod 23.
[0063] With this configuration, during the assembly process, one end of the first connector 41 can be rotatably connected to the first swing arm 22, and the other end of the first connector 41 can be embedded in the connecting rod 23, so as to achieve quick assembly between the first connector 41, the first swing arm 22, and the connecting rod 23.
[0064] In some embodiments, one end of the first connector 41 can be directly inserted into the connecting hole of the first rocker arm 22, and the first connector 41 and the first rocker arm 22 can be clearance-fitted. The other end of the first connector 41 can be embedded into the connecting hole of the connecting rod 23 by heat fusion to improve the connection reliability between the first connector 41 and the connecting rod 23.
[0065] Please see Figures 1 to 3 , Figure 10 In one embodiment of the present invention, the blade 30 includes a second swing rod 31 and a blade body 32; one end of the second swing rod 31 is rotatably connected to the connecting rod 23 via a connector 40; the blade body 32 is connected to the other end of the second swing rod 31.
[0066] With this configuration, the drive motor 21 can drive the first swing arm 22 to swing. The swing of the first swing arm 22, through one of the connecting parts 40, drives the connecting rod 23 to move. The movement of the connecting rod 23, in turn, drives the other connecting part 40 to rotate. Then, through the other connecting part 40, the second swing arm 31 swings. The swing of the second swing arm 31 drives the blade body 32 to rotate, allowing the blade 30 to smoothly switch between open and closed states. Therefore, this embodiment, through the cooperation of the drive motor 21, the first swing arm 22, the connecting rod 23, the connecting part 40, and the second swing arm 31, can more smoothly drive the blade 30 to rotate, thus accurately achieving the automatic opening and closing of the venetian blinds.
[0067] Please see Figures 1 to 3 , Figure 10 In one embodiment of this utility model, the connecting member 40 that connects the second swing rod 31 and the connecting rod 23 is defined as the second connecting member 42. One end of the second connecting member 42 is rotatably connected to the connecting rod 23, and the other end of the second connecting member 42 is embedded in one end of the second swing rod 31.
[0068] With this configuration, during assembly, one end of the second connector 42 can be rotatably connected to the connecting rod 23, and the other end of the second connector 42 can be embedded in the second swing arm 31, so as to achieve quick assembly between the second connector 42, the connecting rod 23 and the second swing arm 31.
[0069] In some embodiments, one end of the second connector 42 can be directly inserted into the connecting hole of the connecting rod 23, and the one end of the second connector 42 can be clearance-fitted with the connecting rod 23. The other end of the second connector 42 can be embedded into the connecting hole of the second rocker arm 31 by heat fusion to improve the connection reliability between the second connector 42 and the second rocker arm 31.
[0070] Please see Figure 1 In one embodiment of the present invention, multiple blades 30 are provided, and the multiple blades 30 are distributed at intervals along the length direction of the connecting rod 23.
[0071] With this configuration, multiple blades 30 are spaced apart along the length of the connecting rod 23. Under the operation of the drive motor 21, the first swing rod 22 can swing. Under the swing of the first swing rod 22, the connecting rod 23 is moved through one of the connecting parts 40. Under the movement of the connecting rod 23, the multiple connecting parts 40 on the connecting rod 23 rotate synchronously. Then, the multiple connecting parts 40 drive the multiple blades 30 to rotate respectively, so that the multiple blades 30 can switch synchronously between the open and closed states. There is no need to set up a corresponding drive structure 20 for each of the multiple blades 30, which simplifies the structural design.
[0072] It should be noted that because the louvers in the relevant technology do not have the function of removing dust and other impurities from the surface of the blades, a large amount of dust and other impurities accumulate at the ventilation openings of the product after long-term use. This not only affects the appearance of the louvers, but also the large amount of dust and other impurities can easily be introduced into the air after long-term use, causing users to breathe in dust and other impurities and causing discomfort.
[0073] Based on the above issues, please refer to Figures 6 to 9 In one embodiment of the present invention, the automatic opening and closing louver 100 further includes a dust removal component 50, which is rotatably disposed on the mounting base 10 and is used to remove impurities from the surface of the blades 30.
[0074] With this configuration, by adding a dust removal component 50 to the automatic opening and closing louver 100 and rotatably connecting the dust removal component 50 to the mounting base 10, the dust removal component 50 can effectively remove dust and other impurities from the surface of the blades 30 under rotation, thereby enabling regular removal of dust and other impurities from the surface of the blades 30 to ensure the cleanliness of the surface of the blades 30.
[0075] In practical applications, the dust collector 50 can be rotated by a motor or manually. In some embodiments, to reduce manufacturing costs, the dust collector 50 can be manually pulled to rotate, thereby removing impurities from the surface of the blade 30.
[0076] Please see Figure 10 In one embodiment of the present invention, the dust removal component 50 has a dust removal side for removing impurities from the surface of the blade 30, and the dust removal side is provided with a brush 51.
[0077] With this configuration, by installing a brush 51 on the dust removal component 50, the dust and other impurities on the surface of the blade 30 can be scraped off and carried away by the brush 51 as the dust removal component 50 rotates, thereby improving the cleaning effect on the surface of the blade 30.
[0078] In some embodiments, the brush 51 can be glued to the dust removal side of the dust removal component 50 to ensure reliable connection between the brush 51 and the dust removal component 50. Of course, in other embodiments, the brush 51 can also be fixed to the dust removal component 50 by means of screws, clips, magnets, etc.
[0079] Please see Figures 6 to 8 In one embodiment of the present invention, one end of the dust removal component 50 is rotatably connected to the mounting base 10; the other end of the dust removal component 50 is provided with a magnetic suction component, and the mounting base 10 is provided with a magnetic suction engagement component. When the dust removal component 50 is in the dust removal position, the magnetic suction component and the magnetic suction engagement component magnetically engage.
[0080] With this setup, after the dust and other impurities on the surface of the rotating and descending blades 30 of the dust collector 50 are cleaned, the dust collector 50 is rotated back to its original position. At this time, the dust collector 50 can be positioned in the dust-to-clean position by the magnetic attraction of the magnetic attraction component and the magnetic attraction engagement component, so as to wait for the next dust removal action.
[0081] In some embodiments, the magnetic suction component can be a magnet, and the magnetic coupling component can be an iron component. The magnet and the dust removal component 50 can be fixed by an interference fit, and the iron component and the mounting base 10 can also be fixed by an interference fit. Alternatively, an anti-detachment screw 52 can be used to rotatably connect one end of the dust removal component 50 to the left end face of the mounting base 10, so that the anti-detachment screw 52 can both serve as a connection to the dust removal component 50 and as a rotating shaft. This allows the dust removal component 50 to rotate around the anti-detachment screw 52 as a rotating shaft when the user manually pulls it; for example, it can rotate clockwise from... Figure 6 Rotate the position to Figure 7 From the position, then clockwise from Figure 7 Rotate the position to Figure 8 The position, then from the counter-clockwise direction... Figure 8 Rotate the position to Figure 7 From the position, then clockwise from Figure 7 Rotate the position to Figure 6 By repeatedly performing this action, the dust and other impurities on the surface of the blade 30 can be cleaned by using the brush 51.
[0082] This utility model also proposes a 3D printer, which includes a housing, a printing platform, a print head, and an automatic opening and closing louver 100. The specific structure of the automatic opening and closing louver 100 is as described in the above embodiments. Since this 3D printer adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0083] The shell encloses a printing cavity; a printing platform is located inside the printing cavity; a print head is located inside the printing cavity; and an automatic opening and closing louver 100 is installed on the shell.
[0084] In some embodiments, the printhead may be positioned above the printing platform and may be movable relative to the housing to print products on the printing platform. The side of the housing with the opening and closing door is defined as the front, and the automatic opening and closing louver 100 may be located on the side or back of the housing.
[0085] It is understandable that by installing an automatic opening and closing louver 100 on the housing, ventilation and lighting effects between the printing cavity and the external environment can be achieved.
[0086] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model.
