The first filter member 610 and the second filter member 620 have the same structure and are spaced apart in a direction perpendicular to the air flow direction. For better understanding, the first filter member 610 and the second filter member 620 are spaced apart in a direction perpendicular to the paper surface, taking the orientation of fig. 3 as an example.

It will be appreciated that the first filter member 610 and the second filter member 620 may have other configurations, such as, for example, a second portion 6120 extending from the first surface 61101 only on the side of the first filter member 610 and the second filter member 620 opposite each other and no second portion 6120 on the side opposite each other, and that when installed, the edges of the sides of the first filter member 610 and the second filter member 620 opposite each other abut the inner wall surface of the air duct, such that air circulates primarily within the tortuous passages formed by the adjacent filter member configurations. Preferably, the number of the filter members is 2-5, and the zigzag channels formed by the structure are 1-4, so that the filter assembly 60 has high filtering capacity and does not obstruct air circulation too much.

Each filter member includes at least one filter structure. When each filter member comprises a plurality of filter structures, at least a portion of the filter structures are non-coplanar with one another. Specifically, each filter structure includes a first portion 6110 and a second portion 6120 that are connected to or formed as a unitary structure with one another. The present invention is not limited to the specific structure of the first portion 6110, for example, the first portion 6110 may be a flat plate-shaped structure, an arc plate-shaped structure, a triangular prism-shaped structure, or the like, on which the first surface 61101 is formed, the first surface 61101 is mainly used for constructing a zigzag channel and a blocking portion for trapping thread scraps, and the first surface 61101 also has a function of guiding air circulation. The second portion 6120 is disposed on a downstream side of the first portion 6110 along the air flowing direction, the second portion 6120 has a second surface, and the second surface and a portion of the first surface 61101 close to the downstream side are configured together to form the blocking portion. The second portion 6120 is not limited in the utility model, for example, the second portion 6120 may be a flat plate structure, a bent plate structure, or the like, as long as it has a second surface capable of forming a barrier with the first surface 61101.

Specifically, as shown in fig. 6, taking the first filter member 610 as an example, it includes five filter structures connected to each other to form an integral structure. Each filter structure includes a first portion 6110 and a second portion 6120, the second portion 6120 extending from a downstream side of the first surface 61101 of the first portion 6110. The first portion 6110 is in a plate-like structure, and the first surface 61101 is located on the windward side of the first portion 6110. The second portion 6120 is a bent plate-like structure. The second portion 6120 includes a body portion 61201, where the body portion 61201 in this embodiment includes a first body portion (not labeled) that extends from the first surface 61101 and a second body portion (not labeled) that extends from an outer edge of the first body portion. A surface of the first main body portion adjacent to the first surface 61101 is defined as a first sub-surface (not labeled), and the first sub-surface and the first surface 61101 have an included angle therebetween, which is an acute angle. A surface of the second main body portion opposite to the first surface 61101 is defined as a second sub-surface (not labeled), and the second sub-surface is parallel to the first surface 61101. The first sub-surface and the second sub-surface together form the second surface in the present invention. In this embodiment, a portion of the first surface 61101, the first sub-surface and the second sub-surface are surrounded to form a blocking portion. Because the air circulating in the air channel in the drying process is humid air, the surface of the blocking part can be kept humid, and the blocking part has certain adsorption capacity. When the moist air enters the blocking portion under the guidance of the first surface 61101, the airflow is blocked and the circulation direction is changed, in the process, the moist air carrying the thread scraps collides with the surface of the blocking portion, so that the thread scraps in the air are adhered to the surface of the blocking portion, the thread scraps are intercepted, and the filtering effect is achieved.

It is to be appreciated that the angle between the first body portion and the first surface 61101 is merely exemplary, and the angle therebetween can also be a right angle or an obtuse angle. The second body portion can also have an included angle with the first surface 61101. In short, the first sub-surface 61101, the first sub-surface and the second sub-surface may have any positional relationship, as long as the structure can form a barrier that can trap the thread scraps. It will also be appreciated that the body structure of the second portion 6120 is also exemplary, and that the body structure may be formed by connecting several plate structures. Further, the edge of the second body portion is also extended to form a turned edge 61202 extending toward the first surface 61101 to further enhance the ability to block thread scraps. The cuff 61202 is perpendicular or approximately perpendicular to the portion of the second surface that is parallel to the first surface 61101.

Further, when the filter member includes at least two filter structures, for example, a first filter structure and a second filter structure, the first filter structure is the same as the second filter structure, and the downstream side of the first filter structure is connected to the upstream side of the second filter structure, the first portion 6110 of the first filter structure and the first portion 6110 of the second filter structure are not coplanar, and have an included angle in the range of 100 ° to 120 °.

As shown in fig. 6, when the first portion 6110 is parallel to the second main body portion of the second portion 6120, the dimension of the first portion 6110 is larger than the dimension of the second portion 6120, which is the distance between the root at the position where the first portion 6110 extends to form the second portion and the free end thereof in one filter structure, viewed in the air flow direction. The second portion 6120 is dimensioned in the same manner. To obtain a better filtering effect, the size of the second portion 6120 is set to 25% to 50%, such as 30%, of the size of the first portion 6110. Further, the distance between the second sub-surface and the first surface 61101 is 6-8 mm, such as 6 mm. Therefore, the thread scraps in the air can be trapped to the maximum extent, and the air circulation is not blocked too much.

In order to facilitate the removal of lint trapped by the filter assembly 60, the filter assembly 60 of the present invention is further provided with a second flushing member 70 to clean the filter assembly 60 by flushing. It will be appreciated that the filter assembly 60 may be further cleaned by manual disassembly and assembly.

The second flushing member 70 has a chamber 701, and one of the ends of the filtering member passes through one of the side walls of the second flushing member 70 corresponding to the chamber 701 and extends to the inside of the chamber 701. The cavity is also connected with a water inlet 702, the water inlet 702 is connected with a water inlet pipe, after water enters the cavity 701 through the water inlet 702, water in the cavity 701 can enter a thread scraps accommodating space formed by the first surface 61101 and the second surface structure from one end of the filtering component corresponding to the cavity 701, and then thread scraps on the surface of the blocking part are washed, so that the filtering assembly 60 is cleaned.

Further, in order to promote smooth flow of water, the entire filter member is inclined with respect to a horizontal plane when the filter member is attached, and the inclination angle is 0 to 45 °, preferably 15 to 45 °. As shown in fig. 3, the height of the right end portion of the filter member is higher than that of the left end portion, and the filter member is inclined from the upper right to the lower left. Under the condition that water enters from the right end part, water flow can smoothly flow to the left end part under the guidance of the obliquely arranged filtering component, and then the cleaning efficiency is improved.

It is understood that the flushing medium may be clean water, wash water, etc.
