Example 2

The filter assembly in this embodiment is further described below:

unlike the filter assembly of embodiment 1, the filter assembly of this embodiment includes a primary filter element 2 having an inlet in communication with or closed against the interior chamber of the second cabinet, and a dust-removing filter screen 3 superposed on the air outlet side of the primary filter element 2, and it should be noted that in this embodiment, the primary filter element 2 is adapted to the first air duct 13 so that the inlet is in communication with or closed against the interior chamber of the second cabinet, corresponding to the presence or absence of air flow through the first air duct 13.

Referring to fig. 3-5, the primary filter 2 in this embodiment includes a frame 21 and a plurality of partitions 23 arrayed along the height direction of the frame 21, wherein two ends of the partitions 23 are connected to the side walls of the frame 21, one end of each partition 23 is connected to the head of the corresponding partition 23, and the other end of each partition 23 is connected to the tail of the corresponding partition 23, so as to fill a neutral filter cloth 22 between the partitions 23.

Referring to fig. 1, the inlet at the second cabinet is composed of a plurality of unblocked through holes, and accordingly, the complete filter cloth in embodiment 1 is always in contact with the air outside the cabinet except for the operation of the equipment, so that the complete filter cloth is extremely easy to mold and deteriorate under the combined action of dust and humidity in the air, and the service life is short. For this purpose, in the present embodiment, a primary filter 2 is provided, which can connect or close the inlet to the inner chamber of the second cabinet, the primary filter 2 is used for directly connecting the filter cloth 22 to the inlet, and in standby, a barrier is formed by a plurality of partitions 23, the filter cloth 22 is placed behind the barrier, and the contact amount between the filter cloth 22 and the air outside the cabinet is reduced, so as to maintain the dryness of the filter cloth 22.

In addition, as the primary filter element, the primary filter element 2 is used for intercepting large particulate matters in the air, and accordingly, when the form of the filter cloth 22 in fig. 7 is changed into the form of the filter cloth 22 in fig. 9, most of the large particulate matters can fall down the slope of the partition plate 23 under the action of gravity and the pressing force provided when the filter cloth 22 is changed from the flat form into the approximately circular form.

In this embodiment, the primary filter element 2 is adapted to the first air duct 13, and how the primary filter element 2 is adapted to the first air duct 13 is described as follows:

referring to fig. 12, the first air duct 13 includes an air duct body 132 connected to the centrifugal fan 5 and a baffle plate 131 rotatably disposed in the air duct body 132, the baffle plate 131 covers the channel, and a main rope 133 passing through a sidewall of the air duct body 132 and freely moving is disposed at the baffle plate 131.

Referring to fig. 3-5, the primary filter 2 further includes a push plate 24 disposed along the height direction of the frame 21, wherein the push plate 24 has a straight inlet and contacts with the plurality of partition plates 23, and a push plate groove 26 corresponding to the end of the push plate 24 is disposed on the inner wall of the frame 21, wherein two ends of the push plate 24 extend into the push plate groove 26, and a spring 27 opposite to the inlet and abutting against the push plate 24 and the groove wall of the push plate groove 26 is disposed in the push plate groove 26, and a secondary rope 28 with two ends respectively connected with the push plate 24 and the primary rope 133 is disposed in the spring 27 in a penetrating manner, so that the push plate 24 is made to approach or separate from the inlet when the baffle 131 is lifted up or turned down relative to the air duct body 132.

In combination with the above description, the rotation of the partition 23 in the frame 21 is controlled by the push plate 24 and the filter cloth 22, that is, when the air duct body 132 does not pass through, the baffle 131 pulls the main rope 133 and the auxiliary rope 28, so that the push plate 24 moves far away from the inlet in the push plate groove 26, and during the moving far away, the push plate 24 presses the plurality of partition 23, so that the plurality of partition 23 face each other from the beginning to the end after pressing and rotating, and a blocking barrier is formed in the frame 21; in contrast, when the air flow pushes the baffle 131 to the air duct body 132 to raise, the elastic filter cloth 22 pushes the corresponding partition plate 23 to rotate reversely and presses the push plate 24 to move reversely, so that the filter cloth 22 is imported in a straight surface, and therefore, in the embodiment, the opening and closing of the primary filter 2 are adapted to the start and stop of the centrifugal fan 5, and thus, the primary filter 2 can work adaptively without electrification control.

In this embodiment, in order to further improve the service life of the filter cloth 22, one end of the end portion at the position of the partition 23 and the adjacent partition 23 is arranged to be close to and fixed at the switching position of the partition 23, and the other end of the end portion is far away from the pull rod 25 at the switching position of the fixed adjacent partition 23, it should be noted that the pull rod 25 has elasticity, accordingly, in combination with the deformation process of the filter cloth 22, the pull rod 25 always contacts with the elastic sheet attached to the end side of the filter cloth 22, and then the elastic sheet starts the vibration member to the filter cloth body to generate vibration, so that large particles are promoted to separate from the filter cloth body.

In the present invention, unless expressly stated or limited otherwise, a first feature "above" or "below" a second feature may include both the first and second features being in direct contact, as well as the first and second features not being in direct contact but being in contact with each other through additional features therebetween.
