[0009] By adopting the above technical solution, when the pipe needs to be cleaned, the driving component moves the cleaning rod toward the pipe rack and extends it into the pipe, and rotates the cleaning rod to clean the pipe. After cleaning, the cleaning rod is moved by the driving component to move the brush head into the drying box, and the hot air blower is started to dry the brush head.

[0010] Optionally, a water outlet is provided at the end of the middle column away from the cleaning rod, and the water outlet passes through the end of the middle column. A sealing plate for sealing the water outlet is slidably connected to the end of the middle column.

[0011] By adopting the above technical solution, when gas is input into the brush head, the sliding sealing plate exposes the water outlet, and the water in the brush head flows out through the water outlet, thereby improving the cleaning efficiency of the brush head.

[0012] Optionally, a sliding cavity is provided at the end of the middle column, and a plate groove is provided on the side wall of the middle column, and the plate groove is connected with the sliding cavity. One end tube of the sealing plate passes through the sliding cavity and is plugged into the side wall away from the center of the middle column at the water outlet, and the other end is located in the plate groove. The sealing plate slides with the sliding cavity, the water outlet and the plate groove perpendicular to the axial direction of the middle column.

[0018] Optionally, a limiting assembly is connected to the pipe rack, and the limiting assembly is used to limit the movement of the pipe on the pipe rack along its axial direction.

[0019] By adopting the above technical solution, when the pipe is cleaned, the brush head and the pipe move relative to each other along their axial direction. The relative friction between the brush head and the pipe may cause the pipe to move. The limiting component can reduce the relative movement between the pipe and the pipe rack, thereby improving the stability of the pipe during cleaning.

[0020] Optionally, a pipe cover is slidably connected to the pipe rack in a vertical direction, and the end of the pipe cover is set to an opening. The limiting assembly includes a linkage gear, a linkage rack and a push rod.

A support rod is connected to the pipe cover, and the bottom of the support rod abuts against one end of the push rod. The linkage rack is hinged to the other end of the push rod, and a spring is connected between the linkage rack and the push rod. The linkage rack is meshed with the linkage gear, and a support rod is connected to the linkage gear. When the support rod rotates to a vertical state, the end of the side wall of the support plate away from the linkage gear abuts against the end of the pipe.

[0021] By adopting the above technical solution, the pipe cover is placed on the pipe when cleaning the pipe. When the inner wall of the pipe is cleaned, water splashed between the cleaning brush and the inner wall of the pipe is blocked by the pipe cover. When the pipe cover moves toward the pipe rack, the bottom of the pipe cover abuts against the top rod, the top rod rotates, and the end of the top plate connected to the linkage rack moves away from the ground. Under the action of the spring, the linkage rack is always engaged with the linkage gear. The linkage rack moves away from the ground to rotate the linkage gear, and the support rod rotates toward the pipe until the support rod abuts against the end of the pipe, thereby realizing the linkage between the movement of the cover and the support rod limiting the pipe.

[0023] 1. After using the brush head, input gas into the cleaning rod and the brush head through the input tube to blow out the water in the cleaning rod and the brush head, speeding up the evaporation rate of the water accumulated in the cleaning rod and the brush head, so as to facilitate cleaning of the brush head;

[0024] 2. When the pipe needs to be cleaned, the driving component moves the cleaning rod toward the pipe rack and extends it into the pipe, and rotates the cleaning rod to clean the pipe. After cleaning, the driving component moves the cleaning rod so that the brush head moves into the drying box, and the hot air blower is started to dry the brush head;

[0025] 3. When the brush head moves toward the pipe, the meshing of the driving gear and the driving rack causes the driving gear to rotate, the second bevel gear drives the first bevel gear to rotate, the nut block rotates, and the screw moves away from the cleaning rod, thereby pushing the connecting rod to move the sealing plate toward the water outlet to block the water outlet.
