Description

Technical Field

[0001] The invention relates to the technical field of ventilation and air exchange, in particular to a ventilation and air exchange filter device for a green building. Background Art

[0002] The so-called green building is a high-quality building that saves resources, protects the environment, reduces pollution, provides people with healthy, applicable and efficient use space, and maximizes the harmonious coexistence of man and nature throughout its entire life cycle. In green buildings, ventilation equipment needs to be installed to create a feeling of being close to nature for the residents. As one of such ventilation equipment, the unpowered hood (hereinafter referred to as the hood) is widely used in industrial plants and residential areas because of its advantages such as no need for electricity, no need for maintenance and replacement, and long service life.

[0003] However, we found in actual use that the existing hood structure is mostly composed of a hood top, a middle ring (including an upper bracket), blades arranged between the hood top and the middle ring, a foot ring (including a lower bracket) and bearings, etc., which mainly use natural wind to drive the turbine of the wind ball to rotate, and use the negative pressure formed by the temperature difference between indoor and outdoor air to drive the wind ball to rotate, and accelerate the parallel air flow into a vertical air flow from top to bottom to achieve the purpose of indoor ventilation. However, we found in actual use that when there is no wind or the wind is weak, the hood cannot rotate. At this time, foreign matter or flying insects and other debris will enter from between the blades and attach to the ventilation duct. Because the hood mainly discharges the foul air in the room, these debris that enter are difficult to be discharged from the hood in the vertical direction, and will continue to remain in the bending position of the ventilation duct near the hood position. After long-term use, a certain amount of foreign matter will accumulate at the bending position, which will affect the normal ventilation and air filtration of the hood. For this reason, we propose a green building ventilation and air filtration device. Summary of the Invention

[0040] See also Figure 1-10 , the present invention provides a technical solution:

[0041] A green building ventilation and air filter device includes a hood body 1, a screw body 2 disposed in the hood body 1, and a pipe body 3 disposed on the hood body 1. The hood body 1, the screw body 2, and the pipe body 3 are all conventional structures and will not be described in detail herein.

[0042] It also includes a fixing cavity 12, which is arranged on one side of the pipe body 3;

[0043] The fan blade 13 is arranged in the fixed cavity 12;

[0044] The cleaning mechanism 4 is arranged in the fixed cavity 12 and is connected to the screw body 2 and the fan blades 13.

[0045] The cleaning mechanism 4 includes an input shaft 41 rotatably disposed in the fixed cavity 12. A connector 5 is disposed between the pipe body 3 and the fixed cavity 12. The connector 5 is connected to the screw body 2 and the input shaft 41. The connector 5 drives the input shaft 41 to connect to the screw body 2.

[0046] The connecting member 5 includes a pulley 51 provided on the screw body 2 and the input shaft 41, respectively, and a belt 52 is provided between the two pulleys 51;

The functional component 9 is used to amplify the force generated by the screw, thereby achieving effective force storage.

[0054] Functional component 9 includes a fixed gear 91 provided on transmission shaft 1 61 , a first crown gear 92 rotatably provided on transmission shaft 2 62 for use with fixed gear 91 , a plurality of intermeshing intermediate crown gears 93 provided on both transmission shafts 1 61 and 62 , and a second crown gear 94 provided on transmission shaft 1 61 , with the intermediate crown gears 93 at both ends meshing with the first crown gear 92 and the second crown gear 94 , respectively;

[0055] An output shaft 95 is rotatably provided in the fixed cavity 12 , and an output gear 96 is provided on the output shaft 95 for use in conjunction with the second crown gear 94 , and the fan blades 13 are provided on the output shaft 95 ;

[0056] A force storage component 10 is provided in the fixed cavity 12, and the force storage component 10 is connected to the functional component 9. The force storage component 10 is used to store force, thereby ensuring that the fan blades 13 rotate to form airflow when released;

[0057] The power storage assembly 10 includes an electric push rod 101 disposed in the fixed cavity 12, a shift plate 102 is provided on the electric push rod 101, an output shaft 95 is rotatably disposed at the end of the shift plate 102, a spring 103 is provided on the output shaft 95, and both ends of the spring 103 are connected to the output shaft 95 and the shift plate 102 respectively;

[0058] A limiter 11 is provided in the fixed cavity 12 to ensure that the spring 103 stores force normally.

[0059] The limiting member 11 includes a ratchet 111 provided on the output shaft 95 , a second ratchet 112 rotatably provided on the shift plate 102 , and a spring piece 113 cooperating with the second ratchet 112 is further provided on the shift plate 102 ;

[0060] The second ratchet 112 is provided with a chamfer, and a push rod 114 is provided in the fixed cavity 12. The push rod 114 movably passes through the shift plate 102 and cooperates with the chamfer on the second ratchet 112;

[0061] A connecting pipe 63 is provided at the bottom of the fixing cavity 12 , and the connecting pipe 63 is respectively connected to the fixing cavity 12 and the pipeline body 3 .

[0062] When in use, the hood body 1 rotates normally under the impetus of natural wind to ventilate the building. During rotation, the screw drives the input shaft 41 to rotate through the pulley 1 51 and the belt 1 52. When the input shaft 41 rotates forward, the input shaft 41 drives the support rod 81 at the bottom to rotate. The ratchet 1 82 on the support rod 81 drives the connected disc 72 to rotate, which in turn drives the transmission shaft 1 61 to rotate forward. At the same time, the input shaft 41 drives the rotating shaft 71 to rotate through the pulley 2 75 and the belt 2 76. The rotation of the rotating shaft 71 drives the support rod 81 at the bottom to rotate in the same direction. Because the ratchet grooves 73 on the two discs 72 are in different directions, the disc 72 on that side does not rotate under this transmission. Therefore, the transmission gears 77 can mesh normally with each other without interference. When the input shaft 41 rotates in the opposite direction, the input shaft 41 drives the bottom support rod 81 to rotate, and the ratchet 1 82 on the support rod 81 cannot drive the connected disc 72 to rotate under this transmission. At the same time, the input shaft 41 drives the rotating shaft 71 to rotate through the pulley 2 75 and the belt 2 76. The rotation of the rotating shaft 71 will drive the bottom support rod 81 to rotate in the opposite direction. Because the ratchet grooves 73 on the two discs 72 are in different directions, the disc 72 on this side can rotate with the ratchet 1 82. Under the action of the transmission gear 77, the transmission shaft 1 61 will be driven to rotate normally, thereby ensuring that the rotation direction of the transmission shaft 1 61 is always consistent.

[0063] The fixed gear 91 on the transmission shaft 1 61 rotates synchronously, driving the first crown gear 92 on the transmission shaft 2 62 to rotate. Then, through the continuous amplification of the intermediate crown gear 93 and the second crown gear 94, the second crown gear 94 drives the output gear 96 to rotate, and the output shaft 95 also rotates, and starts to drive the mainspring 103 to start accumulating force.

[0064] During the power storage process, the ratchet 111, the spring 113 and the second ratchet 112 can be limited to avoid the release of force during the power storage process. After the power storage is completed, the electric push rod 101 drives the displacement, and the output gear 96 is disengaged from the second crown gear 94. At the same time, under the action of the push rod 114, the second ratchet 112 is driven to rotate to one side, so that the second ratchet 112 cannot limit the ratchet 111. At this time, the clockwork spring 103 drives the output shaft 95 to rotate, and at the same time drives the fan blade 13 to rotate, so as to discharge the debris in the pipe body 3 from the end of the pipe body 3.

[0066] See also Figure 1-11 , the present invention provides a technical solution:

[0067] A green building ventilation and air filter device includes a hood body 1, a screw body 2 disposed in the hood body 1, and a pipe body 3 disposed on the hood body 1.

[0080] Functional component 9 includes a fixed gear 91 provided on transmission shaft 1 61 , a first crown gear 92 rotatably provided on transmission shaft 2 62 for use with fixed gear 91 , a plurality of intermeshing intermediate crown gears 93 provided on both transmission shafts 1 61 and 62 , and a second crown gear 94 provided on transmission shaft 1 61 , with the intermediate crown gears 93 at both ends meshing with the first crown gear 92 and the second crown gear 94 , respectively;

[0085] The limiting member 11 includes a ratchet 111 provided on the output shaft 95 , a second ratchet 112 rotatably provided on the shift plate 102 , and a spring piece 113 cooperating with the second ratchet 112 is further provided on the shift plate 102 ;

[0086] The second ratchet 112 is provided with a chamfer, and a push rod 114 is provided in the fixed cavity 12. The push rod 114 movably passes through the shift plate 102 and cooperates with the chamfer on the second ratchet 112;

[0087] A connecting pipe 63 is provided at the bottom of the fixed cavity 12, and the connecting pipe 63 is connected to the fixed cavity 12 and the pipeline body 3 respectively;

[0088] A cleaning tube 14 is provided at the bending position of the pipe body 3 near the hood body 1. The cleaning tube 14 is connected to the pipe body 3. A valve 15 is provided at the connection between the cleaning tube 14 and the pipe body 3. The valve 15 can be a manual valve 15 or an electric control valve 15 without limitation. The setting of the cleaning tube 14 is aimed at the situation where the horizontal pipe length in the pipe body 3 is long, so as to avoid the situation where the airflow generated by the fan blades 13 cannot be discharged by the pipe body 3. This setting method is conducive to the complete discharge of debris.

[0089] When in use, the hood body 1 rotates normally under the impetus of natural wind to ventilate the building. During rotation, the screw drives the input shaft 41 to rotate through the pulley 1 51 and the belt 1 52. When the input shaft 41 rotates forward, the input shaft 41 drives the support rod 81 at the bottom to rotate. The ratchet 1 82 on the support rod 81 drives the connected disc 72 to rotate, which in turn drives the transmission shaft 1 61 to rotate forward. At the same time, the input shaft 41 drives the rotating shaft 71 to rotate through the pulley 2 75 and the belt 2 76. The rotation of the rotating shaft 71 drives the support rod 81 at the bottom to rotate in the same direction. Because the ratchet grooves 73 on the two discs 72 are in different directions, the disc 72 on that side does not rotate under this transmission. Therefore, the transmission gears 77 can mesh normally with each other without interference. When the input shaft 41 rotates in the opposite direction, the input shaft 41 drives the bottom support rod 81 to rotate, and the ratchet 1 82 on the support rod 81 cannot drive the connected disc 72 to rotate under this transmission. At the same time, the input shaft 41 drives the rotating shaft 71 to rotate through the pulley 2 75 and the belt 2 76. The rotation of the rotating shaft 71 will drive the bottom support rod 81 to rotate in the opposite direction. Because the ratchet grooves 73 on the two discs 72 are in different directions, the disc 72 on this side can rotate with the ratchet 1 82. Under the action of the transmission gear 77, the transmission shaft 1 61 will be driven to rotate normally, thereby ensuring that the rotation direction of the transmission shaft 1 61 is always consistent.

[0090] The fixed gear 91 on the transmission shaft 1 61 rotates synchronously, driving the first crown gear 92 on the transmission shaft 2 62 to rotate. Then, through the continuous amplification of the intermediate crown gear 93 and the second crown gear 94, the second crown gear 94 drives the output gear 96 to rotate, and the output shaft 95 also rotates, and starts to drive the mainspring 103 to start accumulating force.

[0091] During the power storage process, the ratchet 111, the spring 113 and the second ratchet 112 can be limited to avoid the release of force during the power storage process. After the power storage is completed, first, the position of the valve 15 is adjusted to connect the pipeline body 3 with the cleaning pipe 14, and the electric push rod 101 drives the displacement, and the output gear 96 is disengaged from the second crown gear 94. At the same time, under the action of the push rod 114, the second ratchet 112 is driven to rotate to one side, so that the second ratchet 112 cannot limit the ratchet 111. At this time, the clockwork spring 103 drives the output shaft 95 to rotate, and at the same time drives the fan blade 13 to rotate to discharge the debris in the pipeline body 3 from the cleaning pipe 14.
