After the rotating fan blade 3 rotates, the rotating column 27 fixed with the rotating fan blade can be driven to rotate, and then the rotating fan blade is transmitted to an intermittent transmission mechanism fixed with the tail end of the rotating column. The intermittent transmission mechanism can drive the ventilation push rod 17 to horizontally move after converting wind energy, so as to drive the ventilation disc 32 to perform piston movement in the ventilation cavity 19, thereby realizing extrusion and expansion of gas in the ventilation cavity and further realizing ventilation between the outside and the indoor.

When the toggle rod 24 is switched from the left chute to the right chute, the vertical turnover seat 7 is not moved, and only when the toggle rod enters the other chute, the vertical turnover seat 7 can complete rotation. The name intermittent drive mechanism, in fact, also provides time for the reset mechanism to operate during this process. The transmission process of the whole transverse surface peripheral rotating seat and the vertical surface Zhou Zhuai is shown in fig. 4-7, and the description of the embodiment 2 is shown.

The main function of the reset component is to make the air exchanging disk 32 return to the original position by the elastic force in the process of switching the toggle rod 24 from the left sliding groove to the right sliding groove, so that the space in the air exchanging cavity is expanded. During this process, gas is drawn in from the outlet aperture 35, i.e. air in the chamber enters the ventilation chamber 19 through the outlet aperture 35.
As shown in fig. 3, the device further comprises an opening and closing device for independently controlling the opening of the air inlet hole 20 and the closing of the air outlet hole 35, or independently controlling the closing of the air inlet hole 20 and the opening of the air outlet hole 35; the opening and closing device comprises a control air inlet hole 20 open and close of air inlet Assembly and control air outlet aperture 35 the on-off air outlet on-off assembly.

in the rightward movement of the air exchange disk 32, the upper air sealing plate 21 fixed to the side end of the air exchange push rod 17 is driven to move rightward, so that the upper air sealing plate 21 covers the air inlet hole 20. At this time, the intake hole 20 is closed.
At the same time, as the sliding rail 9 moves rightwards, the lower driving wheel 10 is driven to move clockwise, the opposite driving wheel 11 meshed with the lower driving wheel moves anticlockwise, the rotating wheel 14 also moves anticlockwise, and the driving block 16 can be driven to move leftwards. In the process, the lower seal 34 leaves the shielded area of the outlet aperture 35.

Example 2
In this embodiment, on the basis of embodiment 1, the transmission process between the transverse face turnover seat and the vertical face turnover seat 7 is fully described again:

Fig. 4 shows the toggle lever 24 about to slide out of the first chute 42, and the arc-shaped transmission plate is rotated to half of the first arc-shaped groove 41.
Fig. 5 shows that after the transverse turnover seat continues to rotate anticlockwise, the toggle lever 24 has slid out of the first chute 42, and the arc-shaped transmission plate 5 rotates to a state in which the first arc-shaped grooves 41 are substantially coincident.
Fig. 6 shows that after the transversal turn-around seat continues to rotate anticlockwise, the tap lever 24 has slid out of the first chute 42 into the second chute 40 adjacent to the first arc-shaped slot 41, at which time the arc-shaped transmission plate 5 rotates to a state of being disengaged from the first arc-shaped slot 41.
Fig. 7 shows that after the transverse turnover seat continues to rotate anticlockwise, the toggle lever 24 has already entered the second chute 40, at this time, the arc-shaped transmission plate 5 rotates from the first arc-shaped groove 41 to the second arc-shaped groove 39 adjacent thereto (has not yet entered the second arc-shaped groove 39), and the toggle lever 24 slides out of the second chute 40 again after the arc-shaped transmission plate 5 comes into contact with the second arc-shaped groove 39, at this time, the vertical turnover seat 7 starts to rotate slowly, and one cycle ends.
Example 3
The present embodiment, based on embodiment 1 and embodiment 2, makes a supplementary explanation for the application scenario of the device again:
in the foregoing embodiments and the present embodiment, the rotating fan blade 3 is rotatable counterclockwise. The rotating fan blade 3 can only rotate in one direction, and the design has the advantages that: the wind direction changes, and once the rotating fan blade 3 rotates clockwise or anticlockwise at high frequency due to wind force, the internal structure is correspondingly processed to a high-speed transmission process. The disadvantage is that the internal machinery is easily damaged, and the disadvantage is that if the left and right movement frequency of the air exchanging disc 32 is high and the single movement amplitude is small, it is moved only a small distance, which easily results in the inefficient air exchanging.
In a use scenario, a worker may mount it on a rooftop, as shown in FIG. 1, with the inlet vents 20 in communication with the outside and the outlet vents 35 in communication with the inside environment.
