[0030] like Figure 1 As shown, the present application discloses a building ventilation device, which includes a mounting plate 1, a non-powered ventilation component, a transmission component, an air guide rotating tube 2, an air collecting mechanism and a plurality of jet blade components. The non-powered ventilation component is arranged on the mounting plate 1 and is rotatably connected to the mounting plate 1. The non-powered ventilation component includes an upper ring body 3, a plurality of arc blades 4 and a lower ring body 5. The upper ring body 3 is fixedly connected to the upper ends of the plurality of arc blades 4, and the lower ring body 5 is fixedly connected to the lower ends of the plurality of arc blades 4. The lower ring body 5 is connected to the mounting plate 1 through a bearing 6, and the lower ring body 5 is sleeved on the inner side of the bearing 6, and the outer side of the bearing 6 is fixedly connected to the mounting plate 1, so that the arc blades 4 rotate under the driving force of the wind, and the lower ring body 5 can rotate freely relative to the mounting plate 1. The air guide rotating tube 2 is arranged in a space enclosed by the plurality of arc blades 4, and the upper end of the air guide rotating tube 2 is connected to the upper ring body 3 through a transmission component, so that the upper ring body 3 drives the air guide rotating tube 2 to rotate through the transmission component when rotating. The upper end of the air-guiding rotating tube 2 is sealed, and the lower end of the air-guiding rotating tube 2 is connected to the air-collecting mechanism. A plurality of jet blade assemblies are arranged at intervals on the air-guiding rotating tube 2, and each jet blade assembly is connected to the air-guiding rotating tube 2. The air-collecting mechanism collects gas, and after collecting a certain amount of gas, releases the gas. The gas passes through the air-guiding rotating tube 2 to reach the jet blade assembly, and is ejected through the jet blade assembly. The ejected gas blows toward the arc-shaped blade 4 to clean dust and other foreign matter on the arc-shaped blade 4. The air-guiding rotating tube 2 drives the jet blade assembly to rotate. Under the rotation of the jet blade assembly, the indoor hot air and dirty air will be assisted to be discharged under the rotation of the jet blade assembly, so as to realize the convection of indoor and outdoor airflows, thereby reducing indoor temperature and humidity and improving indoor air quality.

[0031] Specifically, in order to clean the dust and other foreign matters on the arc blades 4 and improve the indoor and outdoor air exchange rate, in this embodiment, the transmission assembly includes a ring gear 7, a transmission gear 8 and a driven gear 9. The ring gear 7 is sleeved in the upper ring body 3, and the outer side of the ring gear 7 is fixedly connected to the inner side of the upper ring body 3. The transmission gear 8 is arranged on the inner side of the ring gear 7, and the outer side of the transmission gear 8 is meshed with the inner side of the ring gear 7. The driven gear 9 is arranged at the middle position of the inner side of the ring gear 7, and the driven gear 9 is meshed with the transmission gear 8. The driven gear 9 is sleeved on the air guide rotating tube 2 and is fixedly connected to the air guide rotating tube 2. When wind blows towards the arc blades 4, the upper ring body 3 rotates with the arc blades 4, the upper ring body 3 drives the ring gear 7 to rotate, the ring gear 7 drives the transmission gear 8 to rotate, and the transmission gear 8 drives the driven gear 9 to rotate, so that the air guide rotating tube 2 rotates.

[0032] Under the rotation of the air-guiding rotating tube 2, by setting a jet blade assembly on the air-guiding rotating tube 2, the function of cleaning the arc blade 4 while realizing the indoor and outdoor air exchange is realized. Specifically, a plurality of jet blade assemblies are arranged at intervals on the air-guiding rotating tube 2, and the jet blade assembly includes a jet pipe 10 and an exhaust blade 11. One end of the jet pipe 10 is connected to the air-guiding rotating tube 2, and the other end of the jet pipe 10 is arranged opposite to the arc blade 4. The exhaust blade 11 is arranged on the jet pipe 10 at an angle relative to the horizontal plane, and is connected to the jet pipe 10, so that when the exhaust blade 11 rotates, the exhaust blade 11 can better discharge the indoor hot air. The jet pipe 10 is used to connect the air-guiding rotating tube 2, so that the gas passing through the air-guiding rotating tube 2 is ejected from the jet pipe 10, and the gas ejected from the jet pipe 10 is sprayed toward the arc blade 4, which can clean the dust and debris attached to the arc blade 4.

[0033] Among them, the gas flowing in the air guide rotating tube 2 needs to be collected by the gas collecting mechanism, and the gas is collected by the gas collecting mechanism, and the collected gas is released. The released gas passes through the air guide rotating tube 2 and is finally ejected by the jet pipe 10 to achieve the cleaning of the arc blade 4. Specifically, the gas collecting mechanism includes a mechanism box 12, an air storage bag 13, a screw tube 14, a screw nut 15 and a telescopic air bag 16. The upper end of the mechanism box 12 is connected to the mounting plate 1, and the lower end of the mechanism box 12 is provided with an air storage bag 13, and the air storage bag 13 is connected to the mechanism box 12. The screw tube 14 is arranged in the mechanism box 12, the upper end of the screw tube 14 is fixedly connected to the air guide rotating tube 2, and the screw tube 14 is connected to the air guide rotating tube 2, the lower end of the screw tube 14 is rotatably connected to the mechanism box 12, and the lower end of the screw tube 14 is connected to the air storage bag 13 through the air guide tube. A one-way pressure relief valve 17 is arranged in the air guide tube. The outer surface of the lead screw tube 14 is provided with an external thread, and the lead screw nut 15 is arranged in the mechanism box 12, and the lead screw nut 15 is threadedly connected to the lead screw tube 14. The upper end of the telescopic airbag 16 is connected to the lead screw nut 15, and the lower end of the telescopic airbag 16 is connected to the mechanism box 12. The telescopic airbag 16 is provided with an air inlet pipe 18 connected to the outside and an air outlet pipe connected to the air storage bag 13, a one-way air inlet valve 19 is provided in the air inlet pipe 18, and a one-way air outlet valve 20 is provided in the air outlet pipe. The lead screw tube 14 rotates driven by the gas-guiding rotating tube 2. When the lead screw tube 14 rotates in different directions, the lead screw nut 15 moves up and down on the lead screw tube 14. When the lead screw nut 15 moves downward, the telescopic airbag 16 is compressed, so that the external gas enters the telescopic airbag 16 through the air inlet pipe 18 and the one-way air inlet valve 19, and then enters the air storage bag 13 through the air outlet pipe and the one-way air outlet valve 20 for gas collection. When the gas pressure in the air storage bag 13 reaches a certain value (this value can be set), the one-way pressure relief valve 17 automatically opens, and the gas enters the gas-guiding rotating tube 2 from the air storage bag 13, and then is ejected through the jet pipe 10 to achieve the cleaning of the arc-shaped blades 4.

[0034] It should be noted that, since the ring gear 7 and the transmission gear 8 are internally meshed, the ring gear 7 and the transmission gear 8 rotate in the same direction, and the transmission gear 8 and the driven gear 9 are externally meshed, and the transmission gear 8 and the driven gear 9 rotate in opposite directions, so the ring gear 7 and the driven gear 9 rotate in opposite directions. In addition, the radius of the ring gear 7 is larger than that of the driven gear 9, so the rotation direction and rotation speed of the ring gear 7 are different from those of the driven gear 9, so that when the jet pipe 10 rotates, the ejected gas can contact different arc blades 4, and the arc blades 4 are cleaned more comprehensively.

[0035] Furthermore, in order to further clean the arc blade 4 and make the arc blade 4 clean more thoroughly, in this embodiment, a cleaning mechanism is provided on the exhaust blade 11, and the arc blade 4 is further cleaned by the cleaning mechanism. Specifically, the cleaning mechanism includes a liquid storage box 21, a liquid adding branch pipe and a liquid adding main pipe, the liquid storage box 21 is provided on the blade, micropores are provided on the liquid storage box 21, the liquid storage box 21 is connected to the air injection pipe 10 through the micropores, one end of the liquid adding branch pipe is connected to the liquid storage box 21, and the other end of the liquid adding branch pipe is connected to the liquid adding main pipe, and the liquid adding main pipe is provided outside the air guide rotating pipe 2. The cleaning agent is added to the liquid storage box 21 through the liquid adding main pipe via the liquid adding branch pipe. The liquid storage box 21 rotates with the exhaust blades 11, and the cleaning agent is led out from the micropores into the air injection pipe 10. During the rotation, due to the centrifugal motion of the cleaning agent, the cleaning agent led out from the micropores collides with the air and is atomized. The atomized cleaning agent is ejected from the air injection pipe 10 along with the gas and contacts the arc blades 4, thereby further cleaning the arc blades 4.

[0036] The working principle of the utility model is as follows: on the basis of the existing unpowered ventilation assembly, an air guide rotating tube 2 is arranged in the unpowered ventilation assembly, the air guide rotating tube 2 is used to drive the exhaust blades 11 to rotate to realize the exchange of indoor and outdoor air, and then the air guide rotating tube 2 is used to conduct the gas collected and released by the collection mechanism, and finally the gas is ejected through the jet pipe 10, and the ejected gas blows toward the arc blades 4 to clean the arc blades 4. The application uses the air guide rotating tube 2 as a rotating shaft and a gas delivery pipeline, which simplifies the device structure.

[0037] Of course, the present application may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present application.
