[0038] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0039] Embodiment 1

[0040] This embodiment provides a two-way fan 100, including a housing 1 and a partition baffle 2. A fan blade 3 is arranged in the housing 1, and the fan blade 3 is connected to a first driver, and the first driver can drive the fan blade 3 to rotate; the partition baffle 2 is arranged in the housing 1 and divides a suction air duct 4 and a blowing air duct 5 in the inner cavity of the housing 1. The suction air duct 4 is communicated with the air inlet 6 of the fan blade 3, and the blowing air duct 5 is communicated with the air outlet 7 of the fan blade 3; ventilation baffles 8 are arranged at the air inlets of both the suction air duct 4 and the blowing air duct 5 to divide the suction air duct 4 into an inner suction air inlet 9 and an outer suction air inlet 10, and divide the blowing air duct 5 into an inner blowing air outlet 11 and an outer blowing air outlet 12. Both the inner suction air inlet 9 and the inner blowing air outlet 11 can be communicated with an external ventilation system, and both the outer suction air inlet 10 and the outer blowing air outlet 12 are communicated with the external environment; the ventilation baffle 8 is movably connected to the housing 1 to realize the switching of the suction air duct 4 between being communicated with the external ventilation system and being communicated with the external environment, and realize the switching of the blowing air duct 5 between being communicated with the external ventilation system and being communicated with the external environment.

[0041] The two-way fan 100 of the present utility model uses a partition board 2 to partition an air suction duct 4 and a blowing duct 5 in the housing 1, and ventilation baffles 8 are provided at the air inlets of both the air suction duct 4 and the blowing duct 5 to further construct an inner air suction port 9, an outer air suction port 10, an inner blowing port 11, and an outer blowing port 12. The inner air suction port 9 and the inner blowing port 11 can both be connected to an external ventilation system, and the outer air suction port 10 and the outer blowing port 12 are both connected to the external environment. When the two-way fan 100 is applied to a vehicle seat, the air suction mode and the blowing mode can be realized by using the two-way fan 100. In the air suction mode, air is inhaled from the inner air suction port 9 and flows into the air inlet 6 of the fan blade 3, and after being accelerated by the fan blade 3, it is discharged from the air outlet 7 of the fan blade 3 and flows to the outer blowing port 12, thereby realizing seat air suction. In the blowing mode, air is inhaled from the outer air suction port 10 and flows into the air inlet 6 of the fan blade 3, and after being accelerated by the fan blade 3, it is discharged from the air outlet 7 of the fan blade 3 and flows to the inner blowing port 11, thereby realizing seat blowing.

[0042] In this specific embodiment, one end of the ventilation baffle 8 is hinged to the housing 1, and the other end of the ventilation baffle 8 extends into the air suction duct 4 and the blowing duct 5; the ventilation baffle 8 rotates relative to the housing 1, so that the two-way fan 100 can switch between different working modes. The ventilation baffle 8 located in the air suction duct 4 rotates relative to the housing 1 and can contact the housing 1 and the partition board 2 to block one of the inner air suction port 9 and the outer air suction port 10. When the ventilation baffle 8 blocks the inner air suction port 9, the outer air suction port 10 works; conversely, when the ventilation baffle 8 blocks the outer air suction port 10, the inner air suction port 9 works. The ventilation baffle 8 located in the blowing duct 5 rotates relative to the housing 1 and can contact the housing 1 and the partition board 2 to block one of the inner blowing port 11 and the outer blowing port 12. When the ventilation baffle 8 located in the blowing duct 5 blocks the inner blowing port 11, the outer blowing port 12 works, and vice versa.

[0043] In other realizable specific embodiments of the present utility model, the ventilation baffle 8 can be connected to the housing 1 by other connection methods, such as a sliding method. The ventilation baffle 8 is slidably arranged in the housing 1 to achieve the purpose of switching different working modes.

[0044] The two-way fan 100 of the present utility model further includes a second driver 13. Please refer to Figures 1-5 , the second driver 13 is fixed on the housing 1, and the second driver 13 drives the two ventilation baffles 8 to rotate by using a link mechanism. The power is transmitted by the link mechanism, the transmission is reliable, the structure is compact, which is beneficial to reducing vibration and improving the rotation reliability of the ventilation baffle 8. The second driver 13 drives the two ventilation baffles 8 to rotate simultaneously, which is easy to maintain and is beneficial to cost saving at the same time.

[0045] Specifically, the connecting rod mechanism includes a sliding rod 14, a connecting pin 15 and a driving connecting rod 16. The second driver 13 is connected to the sliding rod 14 in a transmission manner. The second driver 13 can drive the sliding rod 14 to slide back and forth. The connecting pin 15 passes through the shell 1 and is connected to the ventilation baffle 8. The connecting pin 15 corresponds to the ventilation baffle 8 one by one. The two ends of the driving connecting rod 16 are respectively rotatably connected to the two connecting pins 15. The sliding rod 14 is connected to a sliding shaft 17. The driving connecting rod 16 is connected to a sliding sleeve 18 adapted to the sliding shaft 17. The sliding shaft 17 can be slidably arranged in the sliding sleeve 18. The reciprocating sliding direction of the sliding shaft 17 is perpendicular to the sliding direction of the sliding rod 14. The driving connecting rod 16 is arranged parallel to the sliding rod 14. The second driver 13 drives the sliding rod 14 to slide back and forth, and the sliding rod 14 drives the driving connecting rod 16 to move left and right. The driving connecting rod 16 drives the ventilation baffle 8 to rotate by using the connecting pin 15. The connecting pin 15 is located between the hinge end and the free end of the ventilation baffle 8. The movement trajectory of the connecting pin 15 is arc-shaped. When the driving connecting rod 16 drives the connecting pin 15 to move, the distance between the driving connecting rod 16 and the sliding rod 14 changes. The driving connecting rod 16 is connected with a sliding sleeve 18. Correspondingly, the sliding rod 14 is connected with a sliding shaft 17. The sliding sleeve 18 is slidably arranged outside the sliding shaft 17. When the sliding rod 14 drives the driving connecting rod 16 to reciprocate, the relative displacement of the two is adapted to ensure the smooth transmission of power. The utility model uses the driving connecting rod 16 to drive the two ventilation baffles 8 to move in linkage.

[0046] At the same time, the housing 1 has a slide groove 19 adapted to the sliding rod 14, and the sliding rod 14 is slidably arranged in the slide groove 19, thereby improving the reciprocating motion accuracy of the sliding rod 14. The housing 1 also has a limiting groove 20 adapted to the connecting pin 15, and the connecting pin 15 is slidably arranged in the limiting groove 20, and the limiting groove 20 corresponds to the connecting pin 15 one by one. The shape of the limiting groove 20 is an arc that matches the motion trajectory of the connecting pin 15, thereby improving the reciprocating motion accuracy of the connecting pin 15, thereby improving the motion reliability of the ventilation damper 8.

[0047] In this specific embodiment, the second driver 13 is drivingly connected to the sliding rod 14 by a transmission mechanism. The transmission mechanism includes a gear assembly 21, a transmission wheel 22, and an eccentric pin shaft 23. The output end of the second driver 13 is drivingly connected to the gear assembly 21. The gear assembly 21 can drive the transmission wheel 22 to rotate, achieving the purpose of speed reduction at the same time. The eccentric pin shaft 23 is connected to the transmission wheel 22 and their axes do not coincide. The sliding rod 14 has a sliding frame 24 adapted to the eccentric pin shaft 23. The eccentric pin shaft 23 is slidably disposed within the sliding frame 24. The relative sliding direction between the eccentric pin shaft 23 and the sliding frame 24 is perpendicular to the reciprocating sliding direction of the sliding rod 14. The second driver 13 drives the transmission wheel 22 to rotate by means of the gear assembly 21. The transmission wheel 22 is eccentrically connected to the eccentric pin shaft 23. During the process of the transmission wheel 22 driving the eccentric pin shaft 23 to rotate, the eccentric pin shaft 23 reciprocally slides within the sliding frame 24, and at the same time drives the sliding frame 24 and the sliding rod 14 to reciprocally slide, realizing power transmission. Using the gear assembly 21 to transmit power has high transmission efficiency and a compact and reliable structure. In other specific embodiments of the present utility model, other transmission structures can also be adopted, such as belt drive or sprocket drive, etc., to meet different working conditions.

[0048] More specifically, the ventilation baffle 8 is connected with a sealing strip. The sealing strip is made of an elastic material, such as sealing sponge, etc., to block the gaps between the ventilation baffle 8 and the housing 1 and the partition baffle 2, improving the sealing performance of the ventilation baffle 8 and further enhancing the structural reliability of the two-way fan 100. In practical applications, the sealing strip can be arranged around the contour of the ventilation baffle 8 to enhance the sealing performance. The sealing strip is detachably connected to the ventilation baffle 8, which is convenient for disassembly and replacement, and there is no need to replace the ventilation baffle 8, saving the use cost.

[0049] In this specific embodiment, the housing 1 is a split structure. The housing 1 includes an upper shell 25 and a lower shell. The upper shell 25 is detachably connected to the lower shell. The fan blade 3 and the partition baffle 2 are both located within the cavity formed by the upper shell 25 and the lower shell. The upper shell 25 and the lower shell can be connected by means of snap fasteners, bolts, etc., which is convenient for the disassembly, installation and maintenance of the two-way fan 100.

The third driver 26 is fixed on the housing 1 and can drive the ventilation baffle 8 to rotate. The two ventilation baffles 8 are respectively driven to rotate by the third driver 26, which is beneficial to reducing the transmission structure and saving the space occupied by the two-way fan 100. In practical applications, the third driver 26 can be selected as a stepping motor.

[0052] The other structures of the two-way fan 100 in this embodiment are the same as those of the two-way fan 100 in Embodiment One, and will not be elaborated here.
