It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] The present invention provides a combined hood. Figure 1-4 As shown, the combined hood includes: a fixed tube 1 installed on the top of the building; a fixing ring 2, which is detachably installed in the fixing tube 1; a hood body 3, which is installed on the fixing ring 2; a light-transmitting plate 4, which is installed on the top of the hood body 3, and the bottom of the light-transmitting plate 4 is provided with multiple light-transmitting surfaces; a clamping ring 14, which is fixed on the top of the fixing tube 1, and the clamping ring 14 is movably mounted on the outside of the fixing ring 2; a plurality of limiting assemblies, a plurality of which are arranged on the clamping ring 14, and the limiting assemblies are used to clamp the fixing ring 2.

[0021] In this embodiment, the fixed tube 1 is the basic part of the entire hood device and is installed on the top of the building. It provides stable support for other parts of the hood. The fixed ring 2 provides support for the hood body 3. This design makes the installation and disassembly of the hood very simple and convenient, greatly increasing the flexibility of use. The hood body 3 is the main functional part of the hood. When the hood body 3 rotates, it can bring out the indoor air, thereby increasing the indoor air flow rate. The light-transmitting plate 4 not only increases the aesthetics of the hood, but also the multiple light-transmitting surfaces at the bottom can provide a certain degree of natural light, further enhancing the practicality of the hood. The clamping ring 14 enables the fixing ring 2 to be firmly fixed on the fixed tube 1 while being easy to disassemble.

[0022] In a further preferred embodiment of the present invention, the limiting assembly includes a spring 15, a support block 16 and a ball 17. The spring 15 is fixed in the retaining ring 14, the support block 16 is fixed on the spring 15, the support block 16 can extend to the outside of the retaining ring 14, the ball 17 is embedded in the support block 16, and two limiting grooves are provided on the fixing ring 2, and the ball 17 can extend into any one of the limiting grooves.

[0023] In this embodiment, the limiting assembly provides elastic support for the entire limiting assembly. When the fixing ring 2 needs to be fixed or released, the elasticity of the spring 15 can ensure the stability and flexibility of the limiting assembly. The support block 16 is the carrier of the ball 17 and also the connecting bridge between the spring 15 and the ball 17. The ball 17 is a key part of the limiting assembly. The design of the ball 17 enables it to roll smoothly in the limiting groove, which is convenient for fixing the fixing ring 2 and also for its disassembly.

[0024] In a further preferred embodiment of the present invention, a support ring 13 is fixedly installed in the fixed tube 1, and a plurality of support beads are installed on the top of the support ring 13. The plurality of support beads can all contact the bottom of the fixed ring 2, and a plurality of air inlets are provided on the hood body 3.

[0025] In this embodiment, the support ring 13 provides additional support for the upper fixing ring 2, and the support beads contact the bottom of the fixing ring 2 to form a stable support surface. This design can ensure that the position of the fixing ring 2 in the fixing tube 1 is stable and not easy to shake or displace. The design of the air inlet can increase the air circulation and improve the ventilation efficiency of the hood. When the hood rotates, these air inlets can introduce outdoor air into the room and discharge the dirty air in the room, thereby keeping the indoor air fresh and flowing.

[0026] In a further preferred embodiment of the present invention, a driving assembly is provided on the top of the hood body 3, and the driving assembly includes a mounting frame 5 fixed on the top of the building, a plurality of electric telescopic rods 6 fixed on the mounting frame 5, a fixing plate 8 installed on the output rods of the plurality of electric telescopic rods 6, a limiting cylinder 9 installed at the bottom of the fixing plate 8, a limiting block 10 movably installed in the limiting cylinder 9, the limiting block 10 is fixedly connected to the light-transmitting plate 4, a motor 7 is installed on the fixing plate 8, and the output shaft of the motor 7 is fixedly connected to the limiting cylinder 9.

[0027] In this embodiment, the mounting frame 5 provides a solid foundation for the entire drive assembly. The electric telescopic rod 6 can adjust the height of the fixed plate 8 through its telescopic function. The limit cylinder 9 cooperates with the limit block 10 to provide restriction and guidance for the specific movement of the hood. Through the drive assembly, the user can actively control the movement of the hood, which makes the use of the hood no longer completely limited by natural wind, increasing its usage scenarios and flexibility.

[0028] In a further preferred embodiment of the present invention, a solar panel 11 is fixed to the top of the mounting frame 5, a battery is provided at the bottom of the solar panel 11, and the angle between the solar panel 11 and the top of the mounting frame 5 is 15 degrees.

[0029] In this embodiment, the solar panel 11 acts as an energy collector, which can convert solar energy into electrical energy to provide power support for the driving components of the hood. The battery is used to store the electricity generated by the solar panel 11 to ensure that the driving components of the hood can still work normally when there is no sunlight or insufficient sunlight. The angle is designed to maximize the efficiency of the solar panel 11 in receiving solar radiation.

[0030] In a further preferred embodiment of the present invention, the motor 7 and the multiple electric telescopic rods 6 are waterproof electrical appliances, an air flow rate sensor 12 is fixedly installed on the fixed tube 1, and the detection probe of the air flow rate sensor 12 extends into the fixed tube 1.

[0031] In this embodiment, the motor 7 and the electric telescopic rod 6 are designed to be waterproof electrical appliances, which means that the motor 7 and the electric telescopic rod 6 can work normally in a humid or rainy environment without being damaged by moisture intrusion. The air flow rate sensor 12 is used to monitor the air flow rate through the fixed tube 1 in real time, providing data support for the intelligent control of the hood.

[0032] In a further preferred embodiment of the present invention, a plurality of the springs 15 are provided with limiting telescopic rods, the plurality of the limiting telescopic rods are fixedly connected to the inner wall of the clamping ring 14, and the plurality of the limiting telescopic rods are respectively fixedly connected to the plurality of the support blocks 16.

The limiting telescopic rods can be firmly fixed in the clamping ring 14, thereby enhancing the stability of the entire limiting assembly, ensuring that the support block 16 can move stably under the action of the spring 15, and limiting the range and direction of its movement.

[0034] To sum up, compared with the relevant technology, this device can drive the hood body 3 to rotate in an environment without natural wind by setting a motor 7 to drive the limit cylinder 9 mounted on the limit block 10 to rotate, thereby reducing the requirements of the device on the use environment. By setting a spring 15 to resist the support block 16 and cooperate with the ball 17, the fixing ring 2 can be supported, effectively preventing the hood body 3 from falling off easily, and facilitating the disassembly of the hood body 3. By setting a light-transmitting plate 4, the device can be made translucent to increase indoor lighting. By setting an electric telescopic rod 6, the height of the limit cylinder 9 can be adjusted, and the normal rotation of the hood body 3 can be ensured in windy weather.
