DETAILED DESCRIPTION OF THE INVENTION
(12) The technical solutions of the present invention are further described below with reference to the specific embodiments of the present invention in conjunction with the accompanied drawings, but the present invention is not limited to the embodiments.
(13) As shown in FIGS. 1-8, one embodiment of a louver canopy includes a frame 1 and a plurality of louvers 2 rotationally connected to a top of the frame 1, the louvers 2 are disposed at intervals and parallel to each other, and the louvers 2 are capable of rotating to close the top of the frame 1 vertically. The top of the frame 1 has four rafters 11 that extend downward obliquely from a center toward an outer side of the frame 1. The louvers 2 are disposed between two of the parallel rafters 11 and arranged along a length direction of the rafters 11 sequentially, and two ends of the louver 2 directly abut against the rafters 11 respectively. Each of the louvers 2 includes an elongated flashing 21, and the flashing 21 includes a first long side 21a and a second long side 21b. A baffle 22 is connected to the first long side 21a of the flashing 21, an elongated first guide groove 23 is formed between the baffle 22 and the flashing 21, and two outlets 231 are respectively disposed at two ends of the first guide groove 23. When the louvers 2 rotate to a closed state, a groove wall of the first guide groove 23 located at a side of the baffle 22 is higher than the flashing 21, an opening of the first guide groove 23 faces upward, and the second long side 21b of the flashing 21 passes over a top of the baffle 22 of an adjacent louver 2 of the louvers 2 and positions above the first guide groove 23 of the adjacent louver 2. The frame 1 is used for support and the top thereof is installed with the louvers 2, the louvers 2 are disposed parallelly at intervals at the top of the frame 1, and the two ends of each of the louvers 2 are equipped with operating devices. Through operation of a user adjustment of a deflection angle of each of the louvers 2 can be realized, the louvers 2 are basically vertical when being opened by rotating, and large spaces are provided between the adjacent louvers 2 to allow light to illuminate through to enhance a brightness inside the canopy. When the louvers 2 are rotated to be closed, the adjacent louvers 2 rotate correspondingly and overlap each other one by one and are completely closed in a vertical direction, so that falling rainwater cannot fall into the canopy. The top of the louver canopy is tilted by disposing the obliquely downwardly extending rafters 11 at the top of the frame 1 and arranging the louvers 2 along the length direction of the rafters 11, so that it is easy for fallen objects to slide downward and not easy to accumulate. Fallen objects, such as leaves, are generally light and thin and can be easily attached on surfaces of the wet louvers 2 and are difficult to clean. This problem can be solved by disposing the louvers 2 including the flashings 21 and the baffles 22 and forming the first guide groove 23 between each of the flashings 21 and each of the baffles 22, wherein the baffle 22 is a bent plate including a first plate connected to the flashing 21, and a second plate connected to the first plate and extending in a direction away from the flashing 21, the first plate and the second plate are connected at an obtuse angle, which is beneficial to increase a water storage capacity of the first guide groove 23. In this way, during the process of raining, rainwater will first gather in the first guide grooves 23, when the first guide grooves 23 are full, the rainwater continues to flow downward. When the rainfall is large, a water flow rate at the top of the canopy is large and can drive the fallen objects to flow downward along with the rainwater. When the rainfall is small, the fallen objects can partially float on a surface of liquid in the first guide grooves 23, in order to prevent the objects from fully adhering on the louvers 2 due to a thin water film between the objects and the louvers 2, and the objects can still flow downward along with the water flow under continuous impact of the rainwater from above, so as to avoid accumulation of the objects adhering on the surfaces of the louvers 2 when the rainfall is small. With the groove wall of the first guide groove 23 located at the side of the baffle 22 being higher than the flashing 21, and the second long side 21b of the flashing 21 passing over the top of the baffle 22 of the adjacent louver 2 of the louvers 2 and positioning above the first guide groove 23 of the adjacent louver 2, it can ensure that after the first guide groove 23 is full, the water current can flow downward toward the adjacent first guide groove 23, which impacts the objects and causes the objects to leave the top of the canopy under the actions of component force of gravity and water flow impulse, thereby avoiding accumulation of the objects. Further, the flashing 21 has a extended section 212 extending toward the first guide groove 23 of the adjacent louver 2, and the second long side 21b is located at an end of the extended section 212. When the louvers 2 rotate to the closed state, the extended section 212 is in a downwardly inclined state, the flashing 21 smoothly transitions from the first long side 21a to the second long side 21b, and specifically, an upper surface of the flashing 21 is arcuate. By disposing the extended section 212 of the flashing 21, the water current and objects flow faster due to the action of component force of gravity, thereby reducing the time of movement of the objects in areas other than the first guide grooves 23, and preventing the objects from adhering on the louvers 2. With the flashing 21 smoothly transitioning from the first long side 21a to the second long side 21b, resistance of the objects being subjected to during the flow can be further reduced, making movement of the objects more smooth to avoid accumulation of objects. Preferably, when the louvers 2 rotate to the closed state, an activity space 3 is formed between the second long side 21b of the flashing 21 and the baffle 22 of the adjacent louver 2 below, and continued rotation of the louvers 2 is capable of causing the adjacent louvers 2 to abut each other. By forming the activity space 3 between the second long side 21b of the flashing 21 and the baffle 22 of the adjacent louver 2 below when the louvers 2 rotate to the closed state, the canopy has better ventilation effect while achieving sheltering from rain, and when it rains, mist or odor generated inside the canopy can diffuse quickly. In addition, after the rain stops, the user can operate the louvers 2 to continue to rotate and compress the activity space 3 to reach an abutment state, and the first guide groove 23 will be tilted due to rotation, the rainwater stored in the first guide groove 23 will overflow and flow downward, so that a small amount of objects left on the top of the canopy after the rain has stopped can successfully leave the canopy by the impact of this part of the rainwater to achieve an active cleaning effect, and further avoid accumulation of objects. The second long side 21b of the flashing 21 is bent and extended to form a flashing flange 211, and when the louvers 2 are rotated to the closed state, the flashing flange 211 is inserted into the first guide groove 23 of the adjacent louver 2. That is, when the louvers 2 are rotated to the closed state, a position of a bottom end of the flashing flange 211 is lower than a position of the top of the baffle 22 of the adjacent louver 2 below. By disposing the flashing flange 211 extending downward relative to the flashing 21 at the second long side 21b of the flashing 21, in the closed state, the flashing flange 211 is positioned directly above the first guide groove 23 of the adjacent louver 2 below, and the position of the bottom end of the flashing flange 211 is lower than the position of the top of the baffle 22 of the adjacent louver 2 below, such that even when a greater external wind force drives water droplets to fall laterally, it is difficult to enter into the canopy through the spaces between the louvers 2. A baffle flange 221 bending toward the flashing 21 is provided at an outer side of the baffle 22, and a drainage groove 24 for water storage is formed between the baffle flange 221 and the baffle 22; that is, the drainage groove 24 is formed between the first plate and the second plate and the baffle flange 221 of the baffle 22. The baffle 22 also serves as part of a groove wall of the drainage groove 24 and part of a groove wall of the first guide groove 23, so that the water in the drainage groove 24 can be discharged through the two outlets 231 at the two ends of each of the first guide grooves 23. When the user rotates to open the louvers 2 to almost reach the vertical state, part of the rainwater trapped in the first guide groove 23 will flow into the drainage groove 24 along the baffle 22 and be constrained by the baffle flange 221, and eventually flow toward two ends of the drainage groove 24 and flow out through the outlets 231, and will not spill inside the canopy when opening the louvers 2.
(14) As shown in FIGS. 1-3 and FIG. 7-11, the top of one embodiment of the frame 1 further has a transverse beam 12, and the louvers 2 are arranged on two sides of the transverse beam 12 respectively. By disposing the transverse beam 12 at the top of the frame 1, arranging the louvers 2 on the two sides of the transverse beam 12, and the rafters 11 extending from the transverse beam 12 toward two sides, a slope of the top of the canopy can be greater under a same height condition, which increases the difficulty of accumulation of objects and is beneficial to space utilization. A second guide groove 13 is disposed along a length direction of a corresponding rafter 11 of the rafters 11, and the second guide groove 13 is located directly below junctions of the corresponding rafter 11 and the louvers 2. The transverse beam 12 has a gutter disposing along a length direction of the transverse beam 12, the gutter is located directly below a junction of the louver 2 and the transverse beam 12, and the gutters 15 located on the transverse beam 12 communicate with the second guide grooves 13 located on the rafters 11. In this way, part of the rainwater flowing down from the junctions of the louvers 2 and the rafters 11 can be collected into the second guide grooves 13, and part of the rainwater flowing down from the junctions of the louvers 2 and the transverse beam 12 can be collected into the gutters to prevent the rainwater from affecting the canopy internally. The frame 1 further includes a plurality of columns 14 supporting the rafters 11, inside each of the columns 14 has a downspout 141 penetrating from top to bottom, and an upper end of each of the downspouts 141 communicates with a lower end of the second guide groove 13 located on each of the rafters 11. By disposing the downspout 141 penetrating from top to bottom inside each of the columns 14 and communicating the upper end of the downspout 141 with the second guide groove 13, rainwater collected in the second guide grooves 13 and the gutters can be discharged along the downspouts 141 inside the columns 14 to further prevent the rainwater from affecting the canopy internally. A bottom of each of the columns 14 is provided with two outfalls 142 facing toward an outer side of the canopy, and the outfalls 142 communicate with a lower end of the downspout 141. By disposing the outfalls 142 facing toward the outer side of the canopy at the bottom of each of the columns 14 to communicate with the downspout 141, the rainwater discharged from the downspouts 141 can flow to the outer side of the canopy through the outfalls 142, such that the canopy will not be affected by the rainwater.

Technicians skilled in the art to which the present invention pertains can make various modifications or additions to the specific embodiments described or replace them in a similar manner, without departing from the spirit of the present invention or beyond the scope defined by the appended claims.
