Description

Technical Field

[0001] This utility model relates to the field of ventilators, and in particular to a thin ventilator with controllable airflow. Background Technology

[0002] A ventilator is a support device for window ventilation, installed on the building's external envelope or between the wall and doors and windows. When in operation, it has certain properties such as wind pressure resistance, water tightness, air tightness, and sound insulation, and can achieve controlled indoor and outdoor ventilation. With the continuous development of technology, people have increasingly higher requirements for the manufacturing process of ventilators.

[0003] Existing ventilators have certain drawbacks in use. First, the original ventilators are basically separate from the baffle and water tank, which increases the risk of rain and water leakage and is not conducive to people's use. In addition, the rain shield of the thin original ventilator is a flat plate that is bent, and the flange that increases rigidity is usually not bent to a large extent. Although this reduces some costs, it also reduces the overall rigidity of the ventilator, making the rain shield more prone to deformation and leakage under strong winds and heavy rain. The rated ventilation volume of the original ventilator is fixed and cannot be adjusted, which brings certain adverse effects to the actual use process. To address these issues, we propose a thin ventilator with controllable air volume. Utility Model Content

[0004] Technical Problem Solved: Addressing the shortcomings of existing technologies, this utility model provides a thin ventilator with controllable airflow. An integrated water guide channel is installed at the lower end of the lower rain shield, reducing splashing and leakage of rainwater flowing down from the upper rain shield and facilitating rainwater drainage. The corrugated rain shield increases the ventilator's lateral rigidity and reduces lateral deformation, significantly enhancing its wind resistance. This allows the ventilator to be made wider without increasing its height, achieving a larger ventilation volume. A push-rod linked valve plate mechanism is added, allowing for real-time adjustment according to actual ventilation needs. This makes the entire system more flexible in environments with strong winds, heavy rain, and extreme heat, providing users with better performance. The adjustable valve plate allows for easy adjustment between 0 and the rated airflow, effectively solving the problems in the background technology.

[0005] Technical Solution: To achieve the above objectives, the technical solution adopted by this utility model is as follows: a thin ventilator with controllable air volume, comprising a ventilator body, a base installed on the bottom side of the ventilator body, a roof panel installed on the side of the base, a guide plate and a flashing plate positioned between the base and the roof panel, a roof purlin positioned at the bottom of the roof panel, an outer perimeter plate positioned on the outside of the ventilator body, and a support plate positioned inside the ventilator body, wherein an upper rainproof plate, a middle rainproof plate and a lower rainproof plate are sequentially arranged from top to bottom on the support plate.

[0006] Preferably, a linkage push rod is installed at the bottom of the ventilator body, a swing rod is provided between the lower rain shield and the linkage push rod, a connecting pin is connected between the swing rod and the linkage push rod, a rotating shaft is connected between the swing rod and the lower rain shield, a valve plate is provided at the position on the lower rain shield where the rotating shaft is connected, and a power push rod is connected between the base and the linkage push rod.

[0007] Preferably, a corrugated plate is provided on the lower side of the lower rain shield, a water guide groove is provided at the bottom of the lower rain shield, a push rod seat is installed between the power push rod and the base, and a coupling is provided between the power push rod and the linkage push rod.

[0008] Preferably, the bottom of the ventilator body is equipped with a linkage push rod via a swing arm, and the valve plate can swing and move. The linkage push rod is oscillating and adjusted by a power push rod.

[0009] Preferably, the lower rain shield is integrally formed with the corrugated plate and the water guide channel by die casting, the power push rod is installed through the push rod seat, and the power push rod moves with the linkage push rod through the coupling.

[0010] Preferably, the upper rain shield, lower rain shield, and lower rain shield are installed inside the ventilator body via a support plate.

[0011] Beneficial Effects: Compared with the prior art, this utility model provides a thin ventilator with controllable airflow, which has the following beneficial effects: This thin ventilator with controllable airflow has an integrated water guide groove at the lower end of the lower rain shield, which reduces the probability of splashing and leakage of rainwater flowing down from the upper rain shield and makes it easier to drain rainwater. The use of a corrugated rain shield increases the ventilator's lateral rigidity and reduces lateral deformation, significantly enhancing the ventilator's wind resistance. It allows the ventilator to be made wider without increasing its height to achieve a larger ventilation volume. The addition of a push rod-linked valve plate assembly mechanism allows for real-time adjustment according to the actual ventilation volume requirements, making the entire system more flexible to use in environments such as strong winds, heavy rain, and extreme heat, and providing users with better performance. The adjustable valve plate allows the product to be adjusted between 0 and the rated airflow. The entire ventilator has a simple structure, is easy to operate, and has better performance than traditional methods. Attached Figure Description
