Abstract
Description
Technical Field
[0001] This utility model relates to the field of roof ventilator technology, specifically a roof ventilator with a sunshade structure. Background Technology
[0002] Roof ventilators are non-powered ventilation devices installed on the roof of buildings. They mainly utilize the thermal pressure effect generated by natural wind pressure and temperature differences to achieve air circulation. They are generally used in industrial plants, warehouses, and other places that require ventilation and cooling.
[0003] According to the existing design of roof ventilators, the exterior of the rotating cylinder does not have a sunshade function. Since the rotating cylinder is exposed to the outside for a long time, the top is constantly exposed to the sun, which can easily lead to insufficient heat insulation. Therefore, its structure needs to be improved.
[0004] Now, a novel roof ventilator with a sunshade structure is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a roof ventilator with a sunshade structure to solve the problem mentioned in the background art that the roof is constantly exposed to the sun, which easily leads to insufficient heat insulation and is not convenient for sun shading.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a roof ventilator with a sunshade structure, comprising a pipe and a movable seat, wherein the movable seat is provided at the top of the pipe, a rotating cylinder is fixedly connected to the outside of the top of the movable seat, a connecting rod is fixedly connected to the inner wall of the pipe, a fixed column is fixedly connected between the connecting rods, a sleeve is sleeved on the top of the outside of the fixed column, and a sunshade is fixedly connected to the top of the sleeve.
[0007] As a further technical solution of this utility model, the sleeve is rotatably fitted onto the outside of the fixed column, and the sunshade is in the shape of an "umbrella".
[0008] As a further technical solution of this utility model, the inner wall of the movable seat is provided with an installation groove, a connecting shaft is fixedly connected between the interiors of the installation groove, and a ball bearing is movably sleeved on the outside of the connecting shaft.
[0009] As a further technical solution of this utility model, the movable seat is rotatably sleeved on the outside of the pipe, and the connecting rod is provided in three sets.
[0010] As a further technical solution of this utility model, the outside of the rotating drum is provided with ventilation openings, and at least ten sets of ventilation openings are provided.
[0011] As a further technical solution of this utility model, a connecting sleeve is fixedly connected to the top of the rotating drum, and the connecting sleeve is rotatably fitted onto the outside of the fixed column.
[0012] As a further technical solution of this utility model, a fixing frame is snapped onto the outside of the vent, and a filter screen is fixedly connected inside the fixing frame. The fixing frame is snapped onto the outside of the vent and is detachable.
[0013] As a further technical solution of this utility model, at least ten sets of balls are provided, and the balls are evenly distributed inside the movable seat.
[0014] Compared with the prior art, the beneficial effects of this utility model are: the roof ventilator with a sunshade structure not only realizes the function of sunshade and smoother rotation, but also realizes the filtration function during ventilation;
[0015] By setting up a fixed column, a sleeve, and a sunshade, the top of the fixed column is fitted with a sleeve, and the top of the sleeve is fixedly connected to the sunshade. The sleeve is fitted on the outside of the fixed column and can rotate. The sunshade is in the shape of an "umbrella". By fitting the sleeve on the outside of the top of the fixed column, the sunshade can provide shade for the rotating cylinder, thus providing it with a certain degree of sun protection.
[0016] The system consists of a pipe, a movable seat, a mounting groove, a connecting shaft, and ball bearings. The movable seat has a mounting groove on its inner wall, and the connecting shaft is fixedly connected between the inside of the mounting groove. Ball bearings are movably fitted onto the outside of the connecting shaft. The movable seat is fitted onto the outside of the pipe and can rotate. The connecting rod has three sets of connections. Because the movable seat is fitted onto the outside of the pipe, when the natural wind drives the rotating drum to rotate, the ball bearings inside can roll on the outside of the pipe, making it easier for the movable seat to rotate on the outside of the pipe and less prone to jamming.
[0017] The system consists of a rotating drum, vents, a fixed frame, a filter screen, and a connecting sleeve. The rotating drum has at least ten vents on its exterior. A connecting sleeve is fixedly connected to the top of the rotating drum, and this sleeve is rotatable and fits onto the outside of the fixed column. A fixed frame is snapped onto the outside of the vents, and a filter screen is fixedly connected inside the fixed frame. The fixed frame is detachably snapped onto the outside of the vents. The filter screen filters external dust during ventilation, preventing impurities from entering the duct through the vents. It also facilitates odor filtering during exhaust.
