[0040] According to the above content, in order to absorb excess cleaning liquid and improve the drying efficiency of the glass curtain wall, the diversion mechanism 2 includes a three-way cover shell 201, the right end of the three-way cover shell 201 is connected to an auxiliary pipe 203, and a second one-way valve 202 is installed on the surface of the auxiliary pipe 203.

[0041] In this embodiment: the upper auxiliary tube 203 is connected to the external cleaning liquid tank through an infusion pump, and the lower auxiliary tube 203 is connected to the external collection box through a centrifugal pump. This design can effectively enable cleaning personnel to hold the weight and reduce labor intensity.

[0042] In an optional embodiment: the outer ring of the three-way cover 201 is fixedly connected to the inner wall of the hollow tube 1.

[0043] In this embodiment, the three-way cover 201 and the hollow tube 1 are fixedly installed to effectively ensure the installation stability of the diversion mechanism 2 and prevent gas or liquid from infiltrating or leaking out at will.

[0044] According to the above content, in order to be able to flexibly adjust the angle of the connecting cover 3 to avoid cleaning dead corners in the glass curtain wall, the positioning and anti-slip mechanism 4 includes a positioning arc hole 401 and an insertion rod 403. The surface of the insertion rod 403 is sleeved with a connecting spring 402. The number of the positioning arc hole 401 and the insertion rod 403 is four. The positioning arc hole 401 is opened on the right side of the surface of the connecting cover 3 and is distributed around the outer ring of the connecting cover 3.

After the rotation of the connecting cover 3 is completed, under the elastic connection action of the connecting spring 402, the insertion rod 403 will automatically reset into the positioning arc hole 401 to avoid the connecting cover 3 from rotating at will without external force.

[0046] The working principle and use process of the utility model are as follows: the upper auxiliary tube 203 is connected to the external cleaning liquid tank through the infusion pump, and the lower auxiliary tube 203 is connected to the external collection box through the centrifugal pump. This design can effectively allow cleaning personnel to hold the weight and reduce labor intensity. The cleaning personnel hold the hollow tube 1, and the sponge roller 501 is close to the glass curtain wall to control the infusion pump to work. The cleaning liquid is introduced into the upper auxiliary tube 203 in one direction, and is sprayed into the connecting cover 3 through the three-way cover 201, the hollow tube 1, the connecting tube 11 and the spray head 9, and sprayed On the sponge roller 501, the cleaning staff drives the hollow tube 1 to move, and the sponge roller 501 can roll, so that the cleaning liquid is evenly coated on the glass curtain wall. Under the elastic support of the return spring 503, when the cleaning staff accidentally applies force, the sponge roller 501 and the installation frame 502 will be retracted into the connecting cover 3, and the return spring 503 will generate impedance force for the cleaning staff, so as to achieve the purpose of elastic cleaning protection. During the cleaning process, when it is necessary to absorb the residual liquid, the cleaning staff will push the connecting cover 3 with force to make the sponge roller 501 retract. The cleaning sponge frame 7 is fixedly bonded to the left side of the connecting cover 3 by Velcro 8, and the frame of the connecting cover 3 is covered by the cleaning sponge frame 7, so that the cleaning staff can clean the cleaning sponge frame 7 and the cleaning sponge frame 7 is cleaned. The cleaning sponge frame 7 serves the purpose of auxiliary cleaning and avoids cleaning dead corners in the glass curtain wall; when the inclination angle of the connecting cover shell 3 needs to be changed, it is only necessary to drive the connecting cover shell 3 to rotate with force, so that the hemispherical block in the insertion rod 403 slides in the positioning arc hole 401, and the insertion rod 403 gradually moves outward, and the connecting spring 402 is stretched. After the rotation of the connecting cover shell 3 is completed, under the elastic connection action of the connecting spring 402, the insertion rod 403 will automatically reset into the positioning arc hole 401 to avoid the connecting cover shell 3 from rotating at will without external force.
