[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0024] See also Figures 1 to 4 According to an embodiment of the utility model, an air guide plate is provided, which is arranged at the outlet of the air duct. The air guide plate comprises: an air guide plate body 1 and a plurality of spacers 2. A first protrusion 11 is provided at the center of one side of the air guide plate body 1 opposite to the outlet of the air duct. The side wall surface of the first protrusion 11 gradually transitions to the edge area of ​​the air guide plate to form an air guide surface 12 for guiding the wind. The plurality of spacers 2 are arranged on the air guide surface 12, and the plurality of spacers 2 are arranged at intervals along the circumferential direction of the air guide plate. An air guiding channel 3 is formed between every two adjacent spacers 2 among the spacers 2 and the air guiding surface 12; wherein each spacer 2 has an air gathering portion 21, which is located on a side of the spacer 2 close to the first protrusion 11, and the air gathering portion 21 is protruded from the first protrusion 11; a air gathering area is formed between each air gathering portion 21, the first protrusion 11 and the air guiding surface 12, so as to gather at least part of the wind coming out of the air duct outlet in the air gathering area, so that the wind gathered in the air gathering area flows out from the air guiding channel 3.

[0025] It can be seen that the air guide plate provided by the utility model is provided with a first protrusion on the air guide plate body 1, and the side wall surface of the first protrusion 11 gradually transitions to the edge area of ​​the air guide plate, thereby forming an air guide surface for guiding the wind, so that the wind from the air duct outlet can be guided to the air guide surface 12 through the first protrusion 11, and then the wind is distributed into the house along the air guide surface 12; at the same time, a plurality of spacers 2 are provided on the air guide surface 12, and each adjacent two spacers 2 of the plurality of spacers 2 and the air guide surface 12 form an air guide channel 3, and each spacer 2 has a wind gathering portion 21, so that most of the wind from the air duct outlet can be first gathered into the wind gathering area through the wind gathering portions 21 on each spacer 2, and then guided into the house through each wind guide channel 3. It changes the initial distribution of the wind flow and avoids the phenomenon of excessively high or low local wind speed caused by directly dispersing and discharging the wind. And through each air guide channel 3, the wind flow can be distributed more evenly, so that the fresh air can be more evenly mixed with the air in the house after entering the house, thereby improving the overall uniformity of the breeding environment. And most of the wind coming out of the air duct outlet is first gathered into the wind gathering area through the wind gathering parts 21 on each partition 2, which can increase the local wind pressure, so that the wind can have a higher momentum when it is guided to the air guide channel, so that it can form a farther jet distance when released. In addition, the wind at the air duct outlet is first gathered into the wind gathering area, and then guided into the house through each air guide channel 3, which can also reduce the turbulence caused by direct impact, which is conducive to forming a more stable and uniform airflow field in the house. The air guide plate has a simple structure and effectively solves the technical problem of the short air jet distance of the air guide plate in the prior art, which causes uneven fresh air in the house.

[0026] Specifically, the wind guide surface 12 is a smooth curved surface, which can help the wind to form a smooth and continuous flow trajectory on the wind guide surface 12 after passing through the first protrusion 11, reduce eddy currents and resistance, and guide the wind more efficiently. The design of the smooth curved surface can also optimize the wind flow distribution, ensuring that the wind flow is more uniform and stable when leaving the wind guide plate.

[0027] Specifically, each spacer 2 is disposed at a distance from the first protruding portion 11 .

[0028] Specifically, the main principle of the above-mentioned wind collecting part 21 is that the wind collecting part 21 is protruded from the first protrusion 11, so that each wind collecting part 21 is like a small wind collector. First, the wind coming out of the air duct outlet blows onto the first protrusion, and then each wind collecting part 21 collects the wind. This concentration effect can increase the local wind pressure, so that the wind energy can have a higher momentum when it is directed to the wind guide channel, so that a longer jet distance can be formed when released. At the same time, since the wind is reorganized and distributed after entering the wind collecting area, the turbulence caused by direct impact is reduced, which is conducive to forming a more stable and uniform airflow field in the house, which is particularly important for animal husbandry that requires precise control of the environment.

[0029] Specifically, the flow area of ​​the air guide channel 3 gradually increases from the air inlet of the air guide channel 3 to the air outlet of the air guide channel 3. With such a structural setting, the flow area of ​​the air guide channel 3 gradually increases from the air inlet of the air guide channel 3 to the air outlet of the air guide channel 3, which can effectively reduce the wind resistance, allowing the wind to enter the house more smoothly, and help maintain sufficient momentum during the jet process to achieve a longer coverage range, while ensuring that the fresh air can be evenly distributed.

[0030] Specifically, Figure 1 and Figure 2 As shown, the spacer 2 also has a second protrusion 22, which is connected to the wind gathering portion 21, and the wind gathering portion 21 and the second protrusion 22 are arranged in sequence along the transition direction of the wind guide surface 12; and the wind gathering portion 21 and the second protrusion 22 form a continuous transition structure; wherein, the cross-sectional area of ​​the wind gathering portion 21 gradually increases along the transition direction of the wind guide surface 12, and the cross-sectional area of ​​the second protrusion 22 gradually increases along the transition direction of the wind guide surface 12.

[0031] The transition structure in the above “the air collecting portion 21 and the second raised portion 22 form a continuous transition structure” means that the shape or contour between the air collecting portion 21 and the second raised portion 22 changes continuously and smoothly without any abrupt geometric transformation.

[0032] Specifically, Figure 1 and Figure 2 As shown, a guide surface 220 is provided on one side of the second protrusion 22 that is opposite to the wind guide surface 12, and the guide surface 220 is a curved surface structure, and the wind guide surface 12 gradually and continuously transitions along the transition direction of the wind guide surface 12. With such a structural setting, a guide surface 220 is provided on one side of the second protrusion 22 that is opposite to the wind guide surface 12, and the guide surface is a curved surface structure, which can guide the wind that is not effectively gathered by the wind gathering portion 21, so that this part of the wind can flow along a predetermined path, thereby reducing airflow turbulence, reducing noise, and improving flow efficiency and distribution efficiency.

[0033] Specifically, Figures 1 to 3 As shown, a connecting hole 4 for installing the air guide plate at the air duct outlet is provided on one side of the air guide plate body 1 opposite to the air guide surface 12. There are multiple connecting holes 4, and the multiple connecting holes 4 are evenly spaced along the circumferential direction of the air guide plate body 1. Each connecting hole 4 extends along the axial direction of the air guide plate body 1; and each connecting hole 4 penetrates to the guide surface 220 corresponding to each connecting hole 4.

[0034] Preferably, there are three connecting holes 4.

[0035] Specifically, the cross section of the spacer 2 is triangular or trapezoidal.

[0036] Specifically, Figure 1 and Figure 2 As shown, the cross section of the first raised portion 11 is circular. With such a structural arrangement, the wind coming out of the air duct outlet can be effectively guided by the first raised portion 11 to ensure that the wind flows in a predetermined direction. And the first raised portion 11 forms a continuous transition with the wind guide surface 12, thereby forming a smooth airflow channel, thereby reducing turbulence and making the wind more orderly. In addition, under the synergistic effect of the first raised portion 11 and the wind gathering portion 21, the wind is effectively gathered and accelerated, and then evenly distributed to the house through the wind guide channel 3, thereby promoting the mixing of fresh air and air in the house and improving ventilation efficiency. At the same time, the cross section of the first raised portion 11 is designed to be circular, which can guide the wind more smoothly, reduce eddy currents and energy losses, and thus improve the flow efficiency of the wind. And it helps to evenly distribute the wind in all directions, avoiding concentration or deviation in a specific direction, thereby helping to improve the uniform distribution of fresh air in the entire house.

[0037] Specifically, Figure 1 and Figure 2 As shown, the side of each spacer 2 away from the first protrusion 11 is aligned with the side wall of the air guide plate body 1.

[0038] Specifically, the air guide plate body 1 and each spacer 2 are integrally formed.

[0039] Specifically, the air guide plate is processed by rotational molding to avoid the problem of hand-laid fiberglass polluting the environment and having poor appearance.

[0040] Specifically, Figure 4 As shown, the air guide plate body 1 is a hollow structure. With such a structural setting, the air guide plate body 1 is designed as a hollow structure, which can effectively reduce the production cost of the air guide plate and facilitate processing.

[0041] Specifically, a concave bonding hole 5 is further provided on one side of the air guide plate body 1 opposite to the air guide surface 12 , so as to improve the overall strength of the air guide plate body 1 , and the concave bonding hole 5 is spaced apart from the connecting hole 4 .

[0042] The utility model further provides a roof air inlet fan, which includes an air guide plate, which is the air guide plate of the above embodiment, and is installed on the air outlet end of the roof air inlet fan, and the air guide surface 12 of the air guide plate is arranged opposite to the air outlet end.

[0043] Specifically, the roof air inlet fan also includes a plurality of fasteners arranged one-to-one corresponding to the plurality of connection holes 4, each fastener is connected to the air outlet end of the roof air inlet fan by passing through the air guide plate, and the air guide plate is installed on the air outlet end of the roof air inlet fan.

[0044] Specifically, the distance between the air guide plate and the air outlet end of the roof air inlet fan can be adjusted according to actual conditions (that is, the distance between the air guide plate and the air outlet end of the roof air inlet fan can be adjusted arbitrarily).

[0045] The utility model provides an air guide plate, which is arranged at the outlet of the air duct, and comprises: an air guide plate body 1 and a plurality of spacers 2, wherein a first protrusion 11 is arranged at the center position of a side of the air guide plate body 1 which is arranged opposite to the outlet of the air duct, and a side wall surface of the first protrusion 11 gradually transitions to an edge area of ​​the air guide plate to form an air guide surface 12 for guiding the wind; a plurality of spacers 2 are arranged on the air guide surface 12, and the plurality of spacers 2 are arranged at intervals along the circumferential direction of the air guide plate, and the plurality of spacers An air guiding channel 3 is formed between every two adjacent spacers 2 and the air guiding surface 12 in 2; wherein each spacer 2 has an air gathering portion 21, which is located at a side of the spacer 2 close to the first protrusion 11, and the air gathering portion 21 is protruded from the first protrusion 11; a air gathering area is formed between each air gathering portion 21, the first protrusion 11 and the air guiding surface 12, so as to gather at least part of the wind coming out of the air duct outlet in the air gathering area, so that the wind gathered in the air gathering area flows out from the air guiding channel 3.

[0046] It can be seen that the air guide plate provided by the utility model is provided with a first protrusion on the air guide plate body 1, and the side wall surface of the first protrusion 11 gradually transitions to the edge area of ​​the air guide plate, thereby forming an air guide surface for guiding the wind, so that the wind from the air duct outlet can be guided to the air guide surface 12 through the first protrusion 11, and then the wind is distributed into the house along the air guide surface 12; at the same time, a plurality of spacers 2 are provided on the air guide surface 12, and each adjacent two spacers 2 of the plurality of spacers 2 and the air guide surface 12 form an air guide channel 3, and each spacer 2 has a wind gathering portion 21, so that most of the wind from the air duct outlet can be first gathered into the wind gathering area through the wind gathering portions 21 on each spacer 2, and then guided into the house through each wind guide channel 3.
