Description

Technical Field

[0001] The utility model relates to the technical field of ventilation equipment, and more specifically, to a ventilation equipment with multi-directional air outlets. Background Art

[0002] Ventilation, also known as air change, is to send sufficient fresh air into the indoor space by mechanical or natural methods, and at the same time discharge the dirty air that does not meet the health requirements in the room, so that the indoor air meets the health requirements and the needs of the production process. Regular ventilation can improve the indoor air quality and is beneficial to health. Ventilation equipment is the main equipment for ventilation work and can be seen everywhere in daily life and production work.

[0003] Based on the above, the inventor found that: the existing ventilation equipment usually can only perform one-way ventilation, that is, it can only adjust the air flow in one direction, and it is not convenient to adjust the air outlet direction, resulting in a large number of ventilation equipment needed to be equipped in the ventilation system to ensure the normal operation of the entire ventilation system. Therefore, in view of this, the existing structure is studied and improved to provide a ventilation equipment with multi-directional air outlets, in order to achieve a more practical purpose.

Movable shafts 11 are arranged on both sides of the dual-axis motor 9. A support plate 12 is sleeved on the outer side of the middle part of the movable shaft 11. Tooth blocks 13 are fixedly connected to both ends of the movable shaft 11. In order to improve the adjustment efficiency of the two groups of blades 5, an adjustment mechanism 4 is provided.

[0030] Refer to Figure 1 , the main air duct 1 and the auxiliary air duct 2 are arranged in a T shape, and the main air duct 1 and the auxiliary air duct 2 are fixedly connected. The fan box 3 is started, and the main air duct 1 drives the auxiliary air duct 2 to perform air exchange work.

[0031] Refer to Figure 2, the two sets of blade plates 5 are arranged vertically, and the bottom end of the blade plate 5 is in contact with the top end of the adjacent blade plate 5. Both the movable ring 6 and the toothed ring 7 are movably connected to the auxiliary air duct 2. One set of vertically arranged blade plates 5 seals one end of the auxiliary air duct 2, while the other set of horizontally arranged blade plates 5 can ensure the smooth air flow at the other end of the auxiliary air duct 2.

[0032] Refer to Figure 3 , the toothed plate 8 is slidably connected to the auxiliary air duct 2, and the top end of the toothed plate 8 penetrates through the top surface of the auxiliary air duct 2. The toothed plate 8 cooperates with the toothed ring 7 to rotate and adjust the blade plate 5. The movable ring 6 ensures the rotational stability of the blade plate 5, thereby adjusting the opening and closing states at both ends of the auxiliary air duct 2 and adjusting the ventilation direction.

[0033] Refer to Figure 4 , the double-shaft motor 9 and the support plate 12 are both fixedly connected to the top surface of the auxiliary air duct 2, and the two support plates 12 are respectively located on both sides of the double-shaft motor 9. When the double-shaft motor 9 is started, under the action of the transmission belt 10, the two movable shafts 11 rotate synchronously.

[0034] Refer to Figure 5 , one end of the transmission belt 10 away from the double-shaft motor 9 is sleeved on the outside of the movable shaft 11.

The main air duct 1 and the auxiliary air duct 2 cooperate to perform the air change and ventilation work. When the air outlet direction needs to be adjusted, start the double-shaft motor 9. Under the action of the transmission belt 10, the two movable shafts 11 rotate synchronously. The support plate 12 ensures the rotational stability of the movable shaft 11. The rotation of the movable shaft 11 drives the toothed block 13 to rotate synchronously, thereby causing the two sets of toothed plates 8 to move synchronously in opposite directions. The toothed plate 8 cooperates with the toothed ring 7 to rotate and adjust the blade plate 5. The movable ring 6 ensures the rotational stability of the blade plate 5. Then, one set of blade plates 5 in the vertical state becomes horizontal, and one set of blade plates 5 in the horizontal state becomes vertical, thereby adjusting the opening and closing states at both ends of the auxiliary air duct 2 and finally adjusting the air duct.
