Description

Technical Field

[0001] This utility model relates to the field of ventilation device technology, and in particular to an energy-saving rainproof ventilator. Background Technology

[0002] In existing ventilator designs, most products lack automatic rain protection, relying on manual adjustment or fixed structures, making them difficult to adapt to sudden weather changes. During rainy days, rainwater can easily enter the room through the vents, affecting the indoor environment and equipment safety. At the same time, the adjustment mechanisms of traditional ventilators are often inefficient, unable to adjust the ventilation status in real time according to environmental parameters, resulting in energy waste and poor ventilation performance.

[0003] In conclusion, an energy-saving, rainproof ventilator is needed to address the shortcomings of existing technologies. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides an energy-saving rainproof ventilator, which aims to solve the above problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving rainproof ventilator, comprising a housing, a fan, and a blade assembly for rainproof ventilation. Both the fan and the blade assembly are mounted on the housing. A rain sensor assembly is installed on the side of the housing away from the fan, monitoring environmental parameters outside the housing. A ventilation adjustment mechanism is installed on the side of the housing near the fan, automatically adjusting the overall tilt angle of the blade assembly according to changes in environmental parameters. By monitoring external environmental parameters in real time through the rain sensor assembly and automatically adjusting the overall tilt angle of the blade assembly according to environmental changes through the ventilation adjustment mechanism, intelligent control of the ventilator's opening and closing states is achieved. This structure automatically closes the blade assembly to prevent rainwater intrusion during rainy weather and opens it to ensure ventilation efficiency during sunny weather, effectively improving the equipment's rainproof reliability, ventilation adaptability, and energy-saving effect. It also reduces the need for manual intervention, has a compact structure, and is highly practical.

[0006] Furthermore, the ventilation adjustment mechanism includes a bracket, a motor, a coupling, a lead screw, a nut, and a transmission assembly. The bracket is connected to the housing, the motor is mounted on the bracket, and the output end of the motor is connected to the lead screw via the coupling. The lead screw is connected to the transmission assembly via the nut, and the transmission assembly is used to adapt and connect the blade assembly.

[0007] Furthermore, the blade assembly includes several blades, and each of the blades has a short shaft at both its left and right ends for adapting to the connection of the transmission component.

[0008] Furthermore, the transmission assembly includes a connecting rod, a connector, and an adapter arm. The connecting rod is connected to a nut via the connector. One end of the adapter arm is connected to the connecting rod, and the other end of the adapter arm is connected to the short shaft of the blade assembly. The number of adapter arms is the same as the number of blades.

[0009] Furthermore, a proximity sensor is installed on the side of the housing near the conductive assembly, and the proximity sensor is used to detect the position information of the connecting rod.

[0010] Furthermore, the proximity sensor is mounted near the top of the connecting rod.

[0011] The beneficial effects of this utility model are:

[0012] 1. In this utility model, by setting up a ground rainfall sensor component, it is possible to monitor external environmental parameters, such as rainfall, in real time, thereby enabling the ventilator to respond intelligently and effectively prevent rainwater intrusion.

[0021] like Figure 1 As shown, an energy-saving rainproof ventilator includes a housing 1, a fan 2, and a blade assembly 3 for rainproof ventilation. Both the fan 2 and the blade assembly 3 are mounted on the housing 1. A rain sensor assembly 4 is installed on the side of the housing 1 away from the fan 2, monitoring environmental parameters outside the housing 1. A ventilation adjustment mechanism 5 is installed on the side of the housing 1 closest to the fan 2, automatically adjusting the overall tilt angle of the blade assembly 3 according to changes in environmental parameters. By monitoring external environmental parameters in real time through the rain sensor assembly 4 and automatically adjusting the overall tilt angle of the blade assembly 3 according to environmental changes through the ventilation adjustment mechanism 5, intelligent control of the ventilator's opening and closing states is achieved. This structure automatically closes the blade assembly 3 to prevent rainwater intrusion during rainy weather and opens it to ensure ventilation efficiency during sunny weather, effectively improving the equipment's rainproof reliability, ventilation adaptability, and energy-saving effect. It also reduces the need for manual intervention, has a compact structure, and is highly practical.

[0022] like Figure 2 As shown, in one embodiment, the ventilation adjustment mechanism 5 includes a bracket 51, a motor 52, a coupling 53, a lead screw 54, a nut 55, and a transmission assembly 56. The bracket 51 is connected to the housing 1. The motor 52 is mounted on the bracket 51, and the output end of the motor 52 is connected to the lead screw 54 through the coupling 53. The lead screw 54 is connected to the transmission assembly 56 through the nut 55. The transmission assembly 56 is used to adapt and connect the blade assembly 3.

[0023] like Figure 2As shown, in one embodiment, the blade assembly 3 includes several blades, and both the left and right ends of the several blades are provided with short shafts 31 for adapting and connecting the conductive assembly 56. The right ends of the several blades are rotatably connected to the housing 1 through the short shafts 31.

[0024] like Figure 2 As shown, in one embodiment, the transmission assembly 56 includes a connecting rod 561, a connector 562, and an adapter arm 563. The connecting rod 561 is connected to the nut 55 through the connector 562. One end of the adapter arm 563 is connected to the connecting rod 561, and the other end of the adapter arm 563 is connected to the short shaft 31 of the blade assembly 3. The number of adapter arms 563 is the same as the number of blades.

[0025] Reference Figure 1 As shown, in one embodiment, a proximity sensor 6 is installed on the side of the housing 1 near the transmission assembly 56. The proximity sensor 6 is used to detect the position information of the connecting rod 561.

[0026] In one implementation, the proximity sensor 6 is mounted near the top of the link 561.

[0027] The working principle of this utility model is as follows: When the rain sensor assembly 4 detects rain or other environmental changes on the outside of the housing 1 (outside the rainproof ventilator), it transmits a signal to the controller. The controller then sends a control command to the ventilation adjustment mechanism 5. The motor 52 in the ventilation adjustment mechanism 5 starts and drives the lead screw 54 to rotate through the coupling 53, causing the nut 55 to move axially along the lead screw 54. The nut 55 drives the connecting rod 561 to move through the connector 562. The connecting rod 561 further pushes the short shaft 31 of the blade assembly 3 through the adapter arm 563, thereby synchronously adjusting the overall tilt angle of all blades. In rainy weather, the blade tilt angle is adjusted to the closed state, effectively blocking rainwater from entering. In sunny or rainless weather, the blade tilt angle is adjusted to the open state, achieving efficient ventilation. The proximity sensor monitors the position of the connecting rod in real time and feeds back to the controller, ensuring the accuracy of the blade tilt angle adjustment and the stability of the system. The whole system achieves energy saving, rainproof, and automatic ventilation functions.
