Technical Field

[0001] The utility model relates to the technical field of ventilation ducts, in particular to an air inlet device for a ventilation duct. Background Art

[0002] A ventilation system is a building environmental control technology that controls the spread and harmful effects of air pollutants through ventilation, dilution, or exhaust, ensuring the quality of indoor and outdoor air. It comprises a complete system consisting of air inlets, exhaust vents, air ducts, fans, cooling and heating systems, filters, control systems, and other ancillary equipment. The air inlet is a crucial component of the ventilation system, directly impacting the quality and efficiency of the air delivered to the room.

[0003] When the quality of external air is poor, it is necessary to consider whether it can enter the room. Some air inlets are kept open and no closed structure is set, which allows external air to enter the room directly, resulting in a decrease in indoor air quality. After the clean external air enters, when it enters the conventional pipe inlet, the efficiency of air flow diffusion is limited by the pipe diameter, and the diffusion efficiency is low.

[0028] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] Example:

[0031] A ventilation duct air inlet device, such as Figure 2 As shown, it includes an air inlet duct 1, a fixing frame 5 is installed on the inner side of the air inlet duct 1, a motor box 6 is installed on one side of the fixing frame 5, and an adjusting rod 10 is installed on the output end of the motor box 6 as a driving mechanism;

[0032] like Figure 2 、 Figure 3 and Figure 4 As shown, a closing plate 9 is also installed on the outside of the adjusting rod 10, and a fixing block 8 installed in the air inlet duct 1 is fixed to the outer end of the closing plate 9, and an air guide mechanism 4 is installed on the outside of the fixing block 8 for guiding the wind to diffuse outward. The air guide mechanism 4 includes an air guide plate 401, and a number of mounting rods 403 are fixedly installed between the air guide plate 401 and the fixing block 8. The outer side of the air guide plate 401 is inclined to guide the wind direction, and a number of reinforcing ribs 402 are also installed at equal angles on the inner side of the air guide plate 401 for reinforcing the inclined part of the air guide plate 401.

[0033] like Figure 1 and Figure 6As shown, a cover body 2 is installed at the exhaust port of the air inlet duct 1, and the inner side of the cover body 2 is open. A mounting bracket 12 is installed at the inner opening of the cover body 2. The mounting bracket 12 is threadedly connected to the adjusting rod 10, and the cover body 2 is slidably connected to the mounting rod 403, so that the driving mechanism can drive the cover body 2 to control the opening and closing of the air inlet duct 1, so that the air inlet duct 1 can control whether air is entering or not. At the same time, the air guide plate 401 can be used to limit the movement of the cover body 2 to prevent the cover body 2 from being detached from the threaded connection with the adjusting rod 10.

[0034] The inner wall of the cover 2 is inclined so that part of the airflow can diffuse outward along the inner wall of the cover 2 after contacting the inner wall of the cover 2, thereby increasing the area for the airflow to diffuse outward, thereby accelerating air exchange and achieving high-efficiency ventilation;

[0035] like Figure 2 As shown, a guide ring 3 corresponding to the cover body 2 is installed on the outside of the outlet end of the air inlet duct 1. The outer surface of the guide ring 3 is arranged in an arc shape, and the contact surface position of the guide ring 3 and the cover body 2 is arranged at an angle to fit the inner wall of the cover body 2. It can reverse the airflow diffusing to the outside along the inner wall of the cover body 2 so that it is in the same direction as the outlet of the air inlet duct 1.

[0036] like Figure 2 As shown, an air guide ring 7 is installed on the outside of the motor box 6, and the outside of the air guide ring 7 is inclined, which can guide the wind direction in the air inlet duct 1 and make it flow out along the inclined outer surface of the air guide ring 7, avoiding excessive wind pressure on the air guide ring 7.

[0037] like Figure 2 and Figure 5 As shown, a filtering mechanism 11 is further provided on the inner side of the air inlet duct 1 for isolating some dust and impurities. Specifically, the filtering mechanism 11 includes a limiting plate 1101. A number of limiting plates 1101 are staggeredly arranged in the air inlet duct 1. The limiting plates 1101 can block the airflow to a certain extent, thereby blocking dust and impurities that may exist in the airflow and causing them to flow downward along the inclined surface of the limiting plates 1101.

[0038] A reinforcement frame 1102 is fixedly installed between the limiting plates 1101 to support the edge of the reinforcement frame 1102, thereby preventing the airflow from vibrating the reinforcement frame 1102 and generating noise such as howling when the airflow passes through the position where the reinforcement frame 1102 is not fixed to the inner wall of the air inlet duct 1.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
