Abstract
Description
Technical Field
[0001] The utility model belongs to a negative pressure fan, in particular to a high-strength negative pressure fan. Background Art
[0002] Negative pressure fan uses the cooling principle of air convection and negative pressure ventilation. It is a machine that naturally draws in fresh air from the opposite side of the installation location - the door or window, and quickly forces the stuffy air in the room to be discharged outdoors. It can improve any poor ventilation problem and has a good cooling and ventilation effect.
[0003] The existing negative pressure fan has a low structural strength and is not stable enough when running at high speed. Utility Model Content
[0004] The main purpose of the utility model is to provide a high-strength negative pressure fan, which has a more stable structure and is more stable during operation.
[0005] To achieve the above purpose, the utility model provides a high-strength negative pressure fan, which includes a fan frame, a cross-shaped fixing plate is arranged on the back of the fan frame, a fan is connected to the cross-shaped fixing plate, and the cross-shaped fixing plate divides the back of the fan frame into four rectangular areas, and X-shaped reinforcement plates are arranged in the rectangular areas.
[0006] The high-strength negative pressure fan provided in the present application has a cross-shaped fixing plate on the back of the fan outer frame. The cross-shaped structure has high structural stability. At the same time, after the four rectangular areas separated by the cross-shaped structure are provided with X-shaped reinforcement plates, the structural strength of the fan outer frame is further improved.
[0007] In a possible implementation, the outer ends of the X-shaped reinforcement plate are arranged at the four corners of the rectangular area. The outer ends of the X-shaped reinforcement plate are arranged at the diagonals, and the structural strength is high.
[0008] In a possible implementation, the cross-shaped fixing plate is provided with a plurality of ventilation holes to ensure smooth airflow.
[0009] In a possible implementation, a fan is connected to the center of the cross-shaped fixing plate, and no ventilation holes are provided at the center of the cross-shaped fixing plate. Because a fan needs to be connected to the center of the cross-shaped fixing plate, not providing ventilation holes can ensure stability.
[0010] In a possible implementation, slots are symmetrically arranged on both sides of the fan outer frame, and reinforcement plates are arranged in the slots. After the slots are arranged on both sides of the fan outer frame and the reinforcement plates are installed, the longitudinal force bearing capacity of the fan outer frame is greatly improved, and the structural strength is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The high-strength negative pressure fan provided in the present application has a cross-shaped fixing plate 2 arranged on the back of the fan outer frame 1. The cross-shaped structure has high structural stability. At the same time, after the four rectangular areas separated by the cross-shaped structure are provided with an X-shaped reinforcement plate 4, the structural strength of the fan outer frame 1 is further improved.
