Description

Technical Field

[0001] This utility model relates to the field of wooden house construction, and in particular to a roof ventilation device for wooden houses. Background Technology

[0002] The primary function of roof ventilation is to improve indoor air quality, promote air circulation, effectively remove hot air, moisture, odors, and harmful gases (such as formaldehyde and carbon dioxide), while introducing fresh air. In summer, ventilation can lower roof temperatures and reduce air conditioning energy consumption; in winter, proper ventilation can prevent condensation buildup and mold growth. Furthermore, good ventilation can extend the building's lifespan, improve living comfort, and align with green and energy-efficient building principles. Natural ventilation methods (such as negative pressure ventilation) are more energy-efficient and environmentally friendly than mechanical ventilation, reducing equipment maintenance costs.

[0003] A search revealed patent publication number CN217420266U, which discloses a roof ventilation and window opening system. The system includes a mounting frame with a shading cavity. Multiple glass panels are rotatably mounted within the shading cavity. The mounting frame has a drive mechanism for rotating the glass panels. A shading cloth is slidably mounted on the mounting frame. The mounting frame also has a linear movement mechanism for driving the shading cloth to cover the shading cavity. A ventilation component is located on the side of the mounting frame. This roof ventilation and window opening system not only facilitates adjustment of shading and lighting conditions but also allows for convenient ventilation and heat insulation. It can also provide rapid ventilation in special circumstances, making it highly practical and suitable for agricultural cultivation.

[0004] While existing technologies can achieve some roof ventilation, they have drawbacks: they lack convenient and effective indoor air exchange functions and rely on traditional structures such as exhaust fans, which are prone to electronic malfunctions. Therefore, we propose a roof ventilation device for wooden houses that solves the above problems. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a roof ventilation device for wooden houses.

[0006] The technical solution of this utility model: A roof ventilation device for a wooden house, comprising a box, an air inlet one, an air inlet two, a rotating plate and a movable plate. The upper end of the box is provided with an air inlet one, and the lower end of the air inlet two is provided with an air inlet two. The rotating plate is provided inside the box between the air inlet one and the air inlet two. The movable plate is provided at the bottom of the box. A connecting rod is rotatably installed between the movable plate and the rotating plate.

[0007] When using this device, the housing is installed on the roof, and filters one and two are installed in their corresponding positions. Normally, the moving plate is closed, allowing airflow through air inlet one. A guide plate facilitates rapid airflow, and sensors detect air temperature and humidity. When ventilation is needed, a linear motor opens the moving plate, which moves to the left. A connecting pipe then drives a rotating plate, connecting the indoor air to the air inlet one through the connecting groove and air inlet three. The high-speed air movement creates negative pressure, expelling the indoor air and achieving ventilation. This device utilizes airflow to ventilate the room, eliminating the need for exhaust fans and reducing the failure rate, making it highly practical.

[0008] Preferably, the box body is provided with channel one and channel two, with air inlet one at both ends of channel one, and air inlet two at one end of channel two, while the other end is closed. The optimized design of channel one and channel two ensures stable airflow and improves ventilation efficiency, and one end of air inlet two is closed.

[0009] Preferably, the surface of the first air inlet is provided with a first filter screen, and the surface of the second air inlet is provided with a second filter screen. The first filter screen and the second filter screen can filter dust, particulate matter and other impurities in the air, thereby improving air quality and providing a dual filtration design.

[0010] Preferably, the air inlet is equipped with guide vanes arranged in a linear array, and the inner wall of the housing between the guide vanes is equipped with alternating sensors. The guide vanes optimize the airflow direction and increase the wind speed. The guide vanes inside the channel are designed in the shape of Tesla valves, which can realize high-speed and smooth unidirectional airflow and enhance the negative pressure ventilation effect.

[0011] Preferably, the air inlet two is provided with a channel two inside, and an air inlet three is provided between channel two and channel one. The setting of air inlet three enables channel one and channel two to form airflow linkage, so that the airflow inside channel two can be combined with the airflow inside channel one.

[0012] Preferably, a linear motor is provided at the lower end of the housing, and the output end of the linear motor is fixedly connected to one side of the moving plate. A communication port is provided at the lower end of the housing, and the moving plate is inserted into the communication port. The linear motor drives the moving plate, which has a fast response speed, stable operation, and reduces manual intervention. The insertion design of the moving plate and the communication port has good sealing performance.

[0013] Preferably, the box body is provided with limiting frames on both sides, the limiting frames are provided with screws, and the upper end of the box body is fixed with a bracket. The limiting frames and screw fixing method make the box body more stable and adaptable to different roof structures. The bracket design makes it easy to adjust the installation angle and optimize airflow guidance.

[0014] I. Compared with the prior art, the advantages of this utility model are as follows:

[0015] Second, this utility model achieves efficient natural ventilation by optimizing the airflow path and utilizing the negative pressure effect, without relying on traditional ventilation fans, thus reducing energy consumption and failure rate. The Tesla valve structure design of the guide plate and the combination of sensors enhance the stability of high-speed airflow and the ability to sense temperature and humidity.

[0016] Third, based on the first beneficial effect, the linear motor-driven moving plate simultaneously opens and closes the rotating plate, ensuring stable operation. It utilizes the negative pressure effect to replace indoor air. The overall structure is simple, energy-saving and environmentally friendly, suitable for roof installation, and has high practicality and market promotion value.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
