Description

Technical Field

[0001] This utility model relates to the field of ventilator technology, and in particular to an induction roof ventilator. Background Technology

[0002] Roof ventilators, also known as roof natural ventilators or rooftop natural ventilators, are mainly used to exchange indoor and outdoor air. However, these ventilation devices are not powered by their own power source and rely on external natural wind for power. When abnormal situations occur in the indoor environment, such as smoke, high temperature, or excessive levels of monitored gases, they cannot ventilate in time. Therefore, most existing roof ventilators are electrically driven devices.

[0003] A search revealed Chinese Patent Publication No. CN221683296U, which discloses an axial flow roof fan, including a duct. Multiple support rods are fixedly installed at the upper end of the duct, and a vent cap is fixedly installed at the upper end of each support rod. This invention, with the use of a cleaning component, effectively cleans dust from the filter screen, achieving the purpose of unclogging and preventing dust from blocking the filter mesh, thus ensuring the filter's performance.

[0004] Although the aforementioned patent can clean the dust on the filter screen, after the motor stops, external dust and impurities will enter the room, which will affect the indoor environment, making it unsuitable for use and impractical. Therefore, it is necessary to design an induction-type roof ventilator to solve the above problems. Utility Model Content

[0005] The main objective of this invention is to provide an induction-type roof ventilator that can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An induction roof ventilator includes a housing. A first rotating rod is rotatably connected to one side of the inner side of the housing via a first rotating shaft. A blade is fixedly connected to the outer surface of the first rotating rod away from the first rotating shaft. A sealing gasket is fixedly connected to the edge of the lower surface of the blade. A water collection groove is formed in the middle of the upper surface of the blade. Drainage grooves are formed on both sides of the bottom wall of the water collection groove. A confluence groove is fixedly connected to the middle of the inner side of the housing. A drain pipe is fixedly connected to the outer surface of the housing near the confluence groove. A one-way valve is fixedly connected to one side of the outer surface of the drain pipe. A dustproof plug is fitted onto one end of the drain pipe.

[0008] To enhance the smoothness of blade rotation, in this invention, a sensor-operated roof ventilator has a second rotating rod fixedly connected to the outer surface of the blade away from the first rotating rod. The second rotating rod is rotatably connected to the housing via a second rotating shaft and penetrates the housing. A sealing ring is fixedly connected to the front side of the housing near the second rotating rod.

[0009] In order to facilitate the synchronous rotation of the blades, as a sensor-operated roof ventilator of this utility model, a connecting arm is fixedly connected to the outer surface of the second rotating rod near the sealing ring, and a connecting plate is rotatably connected to one end of the connecting arm.

[0010] To facilitate installation, in this invention, an induction roof ventilator has a mounting plate fixedly connected to the bottom of the outer surface of the housing. Mounting holes are provided at the four corners of the upper surface of the mounting plate, and a rubber pad is fixedly connected to the lower surface of the mounting plate.

[0011] In order to reduce dust adsorption, as a sensor-type roof ventilator of this utility model, each of the four corners of the upper surface of the shell is fixedly connected to a support column, one end of the support column is fixedly connected to a top plate, and one side of the inner side of the top plate is fixedly connected to an environmental sensor.

[0012] In order to achieve the effect of easy ventilation, as a sensor-type roof ventilator of this utility model, a bracket is fixedly connected to the middle of the inner side of the housing, a motor is fixedly connected to the middle of the bottom wall of the bracket, and a fan blade is fixedly connected to the output end of the motor.

[0013] To achieve a dustproof effect, as an induction roof ventilator of this utility model, a dustproof plate is movably connected to the bottom of the inner side of the shell, and springs are fixedly connected to both sides of the inner side of the dustproof plate. One end of the spring is fixedly connected to a limiting plate, and a limiting groove is opened on the inner side of the shell near the limiting plate.

[0014] In order to facilitate the removal of the dustproof panel, as a sensor-operated roof ventilator of this utility model, a control rod is fixedly connected to the lower surface of the limiting plate, and a guide groove is provided on the lower surface of the dustproof panel near the control rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this utility model, by setting up blades, a water collection trough, a drainage trough, a confluence trough, and a drain pipe, when the fan blades generate airflow, the blades rotate around the first rotating rod, and an airflow channel is formed between multiple blades to achieve airflow overflow and heat dissipation. When the fan blades stop running, the overflow airflow disappears, and the blades naturally droop due to their own weight. The adjacent blades overlap each other to eliminate ventilation gaps, thereby playing a role in dust and water protection. When the blades are closed, external rainwater enters through the opening at the top of the shell, and the water collection trough collects the rainwater. When the blades are unfolded, the rainwater inside the water collection trough flows to the confluence trough through the drainage troughs on both sides, and finally is discharged to the outside through the drain pipe, increasing the practicality of the device.

[0017] 2. In this utility model, the top plate, environmental sensor, fan blades, and dustproof plate are designed to protect the top opening of the housing by shielding it from external dust and rainwater, thus reducing the entry of external dust and rainwater. The environmental sensor allows the device to monitor the external environment and stop operation in time when the external environment is poor. The motor drives the fan blades to rotate, which can accelerate the air circulation and better exchange the indoor and outdoor air to achieve the ventilation effect. The dustproof plate blocks and filters indoor and outdoor dust, extending the service life of the equipment. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] like Figure 1-5 As shown, an induction roof ventilator includes a housing 1. A first rotating rod 2 is rotatably connected to one side of the inner side of the housing 1 via a first rotating shaft. A blade 3 is fixedly connected to the outer surface of the first rotating rod 2 away from the first rotating shaft. A sealing gasket 4 is fixedly connected to the edge of the lower surface of the blade 3. A water collection groove 5 is formed in the middle of the upper surface of the blade 3. Drainage grooves 6 are formed on both sides of the bottom wall of the water collection groove 5. A confluence groove 7 is fixedly connected to the middle of the inner side of the housing 1. A drain pipe 8 is fixedly connected to the outer surface of the housing 1 near the confluence groove 7. A one-way valve 9 is fixedly connected to one side of the outer surface of the drain pipe 8. A dustproof plug 10 is fitted onto one end of the drain pipe 8.

[0027] In practical use, through the arrangement of blades 3, sealing gaskets 4, water collection troughs 5, drainage troughs 6, confluence troughs 7, and drainage pipes 8, the first rotating rod 2 is set on the inner side of the housing 1 via the first rotating shaft, providing rotational support for the blades 3, reducing friction, and making opening and closing more convenient. Multiple blades 3 are horizontally arranged on the top of the inner side of the housing 1, and in the non-working state, adjacent sets of blades 3 overlap each other. The blades 3 are made of high-strength lightweight materials to reduce their own weight. The sealing gaskets 4 are fixed on the lower surface of the blades 3, which can enhance the sealing of the connection between two adjacent blades 3, reduce the ingress of external dust and rainwater, and at the same time prevent the two blades 3 from colliding, thus improving the protection effect and extending the service life. When the fan blades 23 operate and generate airflow, the blades... 3 rotates around the first rotating rod 2, and multiple blades 3 form an airflow channel to achieve airflow overflow and heat dissipation. When the fan blades 23 stop running, the overflow airflow disappears, and the blades 3 naturally droop due to their own weight. The adjacent blades 3 overlap each other to eliminate ventilation gaps, thereby playing a role in dust and water protection. When the blades 3 are closed, external rainwater enters through the top opening of the housing 1, and the water collection tank 5 collects the rainwater. When the blades 3 are unfolded, the rainwater inside the water collection tank 5 flows to the confluence tank 7 through the drainage tanks 6 on both sides, and finally is discharged to the outside through the drain pipe 8. The one-way valve 9 ensures that the rainwater can only be discharged to the outside, preventing the entry of external rainwater. The dustproof plug 10 covers and protects the opening of the drain pipe 8 to prevent external dust from clogging the opening, increasing the practicality of the device.

[0028] In this embodiment, a second rotating rod 11 is fixedly connected to the outer surface of the blade 3 away from the first rotating rod 2. The second rotating rod 11 is rotatably connected to the housing 1 through a second rotating shaft. The second rotating rod 11 passes through the housing 1. A sealing ring 12 is fixedly connected to the front side of the housing 1 near the second rotating rod 11.

[0029] In practical use, the second rotating rod 11 and the sealing ring 12 are used to support the other end of the blade 3 through the second rotating shaft, thereby enhancing the smoothness of the blade 3's rotation. The sealing ring 12 enhances the sealing of the connection between the second rotating rod 11 and the housing 1.

[0030] In this embodiment, a connecting arm 13 is fixedly connected to the outer surface of the second rotating rod 11 near the sealing ring 12, and a connecting plate 14 is rotatably connected to one end of the connecting arm 13.

[0031] In practical use, through the setting of connecting arms 13, multiple connecting arms 13 are rotatably connected to connecting plates 14, so that multiple blades 3 can maintain the synchronicity of rotation, so that there is no interference between blades 3, which facilitates sealing. At the same time, connecting arms 13 and connecting plates 14 can be made of high-strength and lightweight materials to reduce their own weight.

[0032] In this embodiment, a mounting plate 15 is fixedly connected to the bottom of the outer surface of the housing 1. Mounting holes 16 are provided at the four corners of the upper surface of the mounting plate 15, and a rubber pad 17 is fixedly connected to the lower surface of the mounting plate 15.

[0033] In practical use, the mounting plate 15 protrudes from the housing 1, preventing the housing 1 from sliding down during installation. The mounting hole 16 works in conjunction with the external bolts to fix the housing 1, thus enhancing its stability. The rubber pad 17 can enhance the sealing between the mounting plate 15 and the roof, preventing rainwater from entering from the connection between the housing 1 and the roof.

[0034] In this embodiment, support columns 18 are fixedly connected to the four corners of the upper surface of the housing 1, and a top plate 19 is fixedly connected to one end of the support column 18. An environmental sensor 20 is fixedly connected to one side of the inner side of the top plate 19.

[0035] In practical use, the top plate 19 and the environmental sensor 20 are set up, and the support column 18 supports the top plate 19. The top plate 19 has a conical structure, which covers and protects the top opening of the housing 1, reducing the entry of external dust and rainwater, and has good protective performance. The environmental sensor 20 is fixed on the inner side of the top plate 19 and is electrically connected to the controller built into the motor 22. The environmental sensor 20 is a device that can convert changes in the external environment into electrical signals or other forms of output signals. The sensor senses changes in the external environment, such as temperature, humidity, light intensity, etc., through sensitive elements, and then converts these non-electrical signals into electrical signals, so that the device can monitor the external environment. When the external environment is poor, the device will stop operating in time.

[0036] In this embodiment, a bracket 21 is fixedly connected to the middle of the inner side of the housing 1, a motor 22 is fixedly connected to the middle of the bottom wall of the bracket 21, and a fan blade 23 is fixedly connected to the output end of the motor 22.

[0037] In practical use, with the motor 22 and fan blades 23, the bracket 21 is used to support and fix the motor 22. The motor 22 drives the fan blades 23 to rotate, which can accelerate the air circulation and better exchange the indoor and outdoor air to achieve the ventilation effect. The overall performance is more perfect.

[0038] In this embodiment, a dustproof plate 24 is movably connected to the bottom of the inner side of the housing 1. Springs 25 are fixedly connected to both sides of the inner side of the dustproof plate 24. One end of the spring 25 is fixedly connected to a limiting plate 26. A limiting groove 27 is formed on the inner side of the housing 1 near the limiting plate 26.

[0039] In practical use, by setting the dustproof plate 24, pressing the limiting plate 26 compresses the spring 25, and placing the dustproof plate 24 into the bottom of the inner side of the housing 1, the limiting plate 26 is inserted into the limiting groove 27 under the elastic action of the spring 25, thus installing the dustproof plate 24. This increases the ease of installation. The dustproof plate 24 blocks and filters indoor and outdoor dust, extending the service life of the equipment.

[0040] In this embodiment, a control rod 28 is fixedly connected to the lower surface of the limiting plate 26, and a guide groove 29 is provided on the lower surface of the dustproof plate 24 near the control rod 28.

[0041] In practical use, by using the control lever 28 to slide inside the guide groove 29, the limiting plate 26 can be operated to disengage the limiting plate 26 from the limiting groove 27, thereby facilitating the disassembly of the dustproof plate 24, making cleaning and maintenance more convenient and improving the performance.

[0042] Working principle: In use, the mounting plate 15 is fixed to the housing 1 at the designated location by the mounting holes 16 and external bolts. The rubber pad 17 enhances the sealing of the connection between the mounting plate 15 and the roof. The motor 22 drives the fan blades 23 to rotate. The airflow generated by the operation causes the blades 3 to rotate around the first rotating rod 2. An airflow channel is formed between multiple blades 3, exchanging the air inside and outside the house. The dustproof plate 24 blocks and filters dust from inside and outside the house. When the fan blades 23 stop running, the overflow airflow disappears. The blades 3 naturally droop due to their own weight. The adjacent blades 3 overlap each other to eliminate ventilation gaps. The top plate 19 covers and protects the top opening of the housing 1, reducing the entry of external dust and rainwater. Even if rainwater enters from the top opening of the housing 1, the water collection tank 5 collects the rainwater. When the blades 3 are unfolded, the rainwater inside the water collection tank 5 flows to the confluence tank 7 through the drainage tanks 6 on both sides, and finally is discharged to the outside through the drain pipe 8, increasing the practicality of the device.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
