through holes in the filter belt 3 are pulled, that is, the dust which is blocked in the filter belt 3 is not blocked, the dust can be blown out better, the filter belt 3 can be cleaned better, the filter belt 3 which blocks the air inlet 2 each time is clean, the ventilation effect in the cabinet 1 is better ensured, the heat dissipation is better, after the rack 823 moves to the position of the guide plate 832, the arc-shaped block 859 touches the guide plate 832, after that, the arc-shaped block 859 moves downwards, after that, the arc-shaped block 859 does not block the ninth support plate 856, so that the second guide block 853 loses the supporting force, after that, the filter belt 3 is stretched before, a great elastic force is exerted, after that, a great force is exerted on the rope 84, and then the first guide block 841 is exerted, so that a great force is exerted to reset the first guide block 841, i.e. the first guide block 841 is moved in the direction of the arc-shaped block 859, after which the arc-shaped block 859 does not block the ninth support plate 856, the first guide block 841 moves together with the ninth support plate 856 in the direction of the arc-shaped block 859, after which the arc-shaped block 859 is positioned below the ninth support plate 856, after which the rope 84 is quickly reset, i.e. the lifting plate 86 and the pulling roller 88 are quickly reset, after which the rack 823 moves away from the guide plate 832, the rack 823 rotates the gear 824, thereby rotating the two seventh shafts 63, driving the filter belt 3, after which the second guide block 853 contacts the third guide block 923 after the rack 823 moves to the extreme end, after which the second guide block 853 does not move, but the rack 823 continues to move, i.e. the second guide block 853 is made stationary, that is, the first guide block 841 is stationary, and then the arc-shaped block 859 is reset along with the rack 823, but the position of the ninth support plate 856 is not moved, so that the arc-shaped block 859 and the ninth support plate 856 can be at the initial matching position, that is, reset is realized, that is, the filter belt 3 can be intermittently driven, the filter belt 3 can not be stretched when the filter belt 3 is driven, and the filter belt 3 can be stretched when the filter belt 3 is not driven;
as the time of use increases, the filter belt 3 wears, resulting in a thinner portion, and the filter belt 3 is less flexible, and slack occurs, after which the elastic force of the second spring 854 pretensions the first guide block 841, so that the filter belt 3 is automatically pretensioned by the tension roller 88, and is not too slack, after which the filter belt 3 is thinner, so that the section is less flexible, after which the filter belt 3 is slack, after which the filter belt 3 is thinner, so that the upper two seventh rotating shafts 63 are pressed against the filter belt 3, i.e. the upper seventh rotating shafts 63 are pressed against the filter belt 3 by the first spring 66 and the second guide rod 68, so that the guide wheel 87 moves the seventh rotating shafts 63 downward to press the filter belt 3, the downward movement of the seventh rotating shaft 63 drives the adjusting plate 911 to move downward, and then the fixing plate 912 is fixed, and the plurality of second links 913 are hinged together, that is, the adjusting plate 911 drives the second hinge rod 915 to move downward, so that the plurality of second links 913 are unfolded, that is, a point of the downward movement of the adjusting plate 911 is moved to be enlarged, so that the angle rod 921 is driven to move downward, so that the third link 922 is driven to move, and the third link 922 pushes the third guide block 923 to move toward the direction close to the guide plate 832, so that the position of the third guide block 923 against the second guide block 853 is forward, that is, the position of the first guide block 841 is forward, that is, the tension of the first guide block 841 against the tension roller 88 is increased, so that the pretensioning effect on the filter belt 3 is increased.
It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
