Therefore, as shown, Figure 3 As shown, the arc-shaped groove 123 and the force application plate 1221 form a hand accommodating cavity for accommodating hands and providing a force application point for hands.

[0062] As an optional embodiment of the filter screen structure of the utility model, the filter screen dismounting body 121 is a cavity column, the cavity column is composed of a top plate 1211, a side plate 1212, an inclined plate 1213 and two end covers 1214, and the top plate 1211, the side plate 1212, the inclined plate 1213 and the two end covers 1214 are integrally formed to ensure the structural integrity of the filter screen dismounting body, and also optimize the mechanical strength of the filter screen dismounting body structure.

[0063] Further, in order to adapt to the structure of the filter screen, the top plate 1211 is perpendicular to the side plate 1212 and parallel to the second stop plate 142, the side plate 1212 is parallel to the first stop plate 141 and abuts against the first stop plate 141, the included angle between the side plate 1212 and the inclined plate 1213 is an acute angle, the inclined plate 1213 smoothly connects the force application part 122 through the arc-shaped groove 123, the first stop plate 141 abuts against the side plate 1212 to prevent the filter screen dismounting mechanism from being separated from the filter screen 11, and the second stop plate 142 is tangent to the inner lowest point of the arc-shaped groove 123 to support the arc-shaped groove.

[0064] In order to save internal space and achieve the connecting and fixing effect of the filter screen and the filter screen dismounting mechanism, such as Figure 4 As shown, the buckle mechanism 13 includes at least one filter screen buckle assembly 131 (in actual application, three filter screen buckle assemblies 131 are arranged) and at least one clamping hook 132. The number of the filter screen buckle assemblies 131 is equal to the number of the clamping hooks 132. Continue to refer toFigure 1 The filter screen buckle assembly 131 is arranged on the first frame 111 or the second frame 112 (in actual application, the filter screen buckle assembly 131 is arranged on the first frame 111). Specifically, the filter screen buckle assembly 131 is arranged in the gap of the first stop plate 141, and each filter screen buckle assembly 131 includes a boss 1311 (such as Figure 2 As shown) and a filter buckle 1312, the top of the boss 1311 is provided with a socket, which passes through the first frame 111 or the second frame 112 (in this embodiment, the socket passes through the first frame 111).
