DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1 As shown, a convection air purification skylight includes a ventilation duct 1, a baffle plate 3 is fixedly connected to the rear of the inner surface of the horizontal part of the ventilation duct 1, a filtering device 2 is provided at the front of the inner surface of the horizontal part of the ventilation duct 1, a drainage square tube 4 communicating with the inner cavity of the ventilation duct 1 is fixedly connected to the lower part of the outer surface of the horizontal part of the ventilation duct 1, the drainage square tube 4 is placed between the filtering device 2 and the baffle plate 3, a driving assembly 7 is slidably connected to the lower part of the outer surface of the vertical part of the ventilation duct 1, a base 5 is fixedly connected to the lower end of the driving assembly 7, and a plurality of screws 6 are threadedly connected to the outer side of the upper end of the base 5 in a circular array.

[0026] In the specific implementation process of this scheme, a plurality of screw rods 6 and a base 5 will be used to install the device on the opening at the top of the roof. If there is wind on that day, the driving component 7 can be used to adjust the direction of the air inlet of the ventilation pipe 1 according to the wind direction of the day, so that the cool wind from the outside directly enters the room, and the air is filtered through the filter device 2 to ensure the cleanliness of the air, and then discharged from various air outlets in the room to form convection air to purify the indoor air. In this process, there is no need to start the fan 21, which saves electricity. If the fan 21 needs to be turned on, the fan 21 can be directly started, and the filter device 2 can be used to filter the air to ensure the cleanliness of the air, and the indoor air purification can still be performed.

[0027] Specifically, in order to ensure the quality of air purification, refer to Figure 2 Figure 4 and Figure 5 The filter device 2 includes a fan 21, a rotating shaft 24 is fixedly connected to the rear end of the rotating shaft of the fan 21, a scraper 23 is fixedly connected to the rear of the outer surface of the rotating shaft 24, and a filter assembly 22 is provided at the front of the outer surface of the rotating shaft 24;

[0028] For further information, see Figure 2 , the fan 21 is fixedly connected to the ventilation pipe 1;

[0029] For further information, see Figure 5 The filter assembly 22 includes two connection frames 222, and the ends of the two connection frames 222 close to each other are fixedly connected to the filter plate 221, and the upper ends of the two connection frames 222 are fixedly connected to the fixing blocks 223, and the right end of the fixing block 223 located on the right is threadedly connected to the second screw 224 on the left side of the fixing block 223 that sequentially penetrates the two fixing blocks 223 and extends to the left side of the fixing block 223 on the left side, and the second screw 224 is threadedly connected to the fixing block 223 on the left side;

[0030] For further information, see Figure 5 The front end of the scraper 23 is attached to the rear end of the filter plate 221, the two connecting frames 222 are slidably connected to the ventilation pipe 1, the two filter plates 221 and the two connecting frames 222 are close to each other, and the two filter plates 221 are attached to the outer surface of the rotating shaft 24;

[0031] A driving motor is installed inside the fan 21 to operate the fan 21. The coupling at the output end of the motor is fixedly connected to the rotating shaft 1 24 so that the rotating shaft 1 24 can be smoothly driven to rotate when the fan 21 rotates.

[0032] The two filter plates 221 and the connection frame 222 are fixedly connected by screws or buckles, and can be released to separate them.

[0033] It can be seen that when the fan 21 is started, the outside air can be drawn into the ventilation pipe 1, and the air is filtered through the two filter plates 221, and dust and other impurities are filtered on the rear side of the two filter plates 221. The impurities can be directly discharged to the outside through the drainage square tube 4. At this time, the rotating shaft 24 is driven to rotate together so that the scraper 23 can be driven to rotate together, and the scraper 23 can be driven around the rotating shaft 24 to scrape the dust on the surface of the two filter plates 221, so as to avoid the two filter plates 221 being blocked due to long-term use and affecting the air purification quality. At the same time, under the action of the shielding plate 3, other debris is prevented from falling into the ventilation pipe 1 and causing damage to other internal components. At the same time, if rainwater hits the horizontal part of the ventilation pipe 1 on rainy days, it will be directly discharged through the drainage square tube 4.

[0034] In addition, after using for a period of time, if the two filter plates 221 need to be replaced, the screw 224 can be rotated to release the fixation of the left fixed block 223, and then the two connecting frames 222 can be pulled outward to replace the filter plates 221. After the replacement is completed, the two connecting frames 222 are installed back into the ventilation duct 1, and the screw 224 is rotated again to connect the two fixed blocks 223 together, and the two connecting frames 222 are fixed so that the ends of the two filter plates 221 that are close to each other are tightly attached.

[0035] Specifically, in order to adjust the air inlet direction, refer to Figure 2 and Figure 3 The driving assembly 7 includes a bottom ring 72, an outer gear ring 73 is fixedly connected to the lower part of the outer surface of the vertical part of the ventilation pipe 1, a gear 75 is meshedly connected to the outer surface of the outer gear ring 73, a motor 74 is fixedly connected to the middle part of the lower end of the gear 75, and a housing 71 is rotatably connected to the lower part of the outer surface of the ventilation pipe 1;

[0036] Further, referring to the figure, the bottom ring 72 is rotatably connected to the lower end of the ventilation pipe 1, the housing 71 is fixedly connected to the upper end of the base 5, and the motor 74 is fixedly connected to the housing 71;

[0037] It can be seen that when the direction of the air inlet of the ventilation duct 1 needs to be adjusted according to the wind direction of the weather, a weather vane or a mobile phone application can be used to detect the current wind direction, and then the motor 74 is started to drive the gear 75 to rotate, which can drive the outer gear ring 73 to rotate, and the ventilation duct 1 can be driven to rotate together, so that the ventilation duct 1 rotates on the inner surface of the outer shell 71 and the upper end of the bottom ring 72, thereby changing the direction of the air inlet of the ventilation duct 1 so that fresh air can smoothly enter the room. At the same time, in conjunction with the windows, convection is formed to enhance and optimize the ventilation effect.

[0038] It should be noted that the specific installation method of the motor 74, the circuit connection method and the control method used in the present invention are all conventional designs, and the present invention will not elaborate on them in detail.

[0039] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
