In view of the setting of "when the cleaning front end contacts the surface of the target inner wall, the cleaning rod 2 axially forms an included angle α with the target inner wall surface, 0° < angle α < 90°", the two shown in the figure are proposed. A preferred embodiment: one is to set the installation base plate 1 and the cleaning rod 2 to be perpendicular to the cleaning rod 2 as shown in FIG. 9 . In this way, when the integral cleaner is in use, an angle is formed between the installation base plate 1 and the surface of the target inner wall surface. β; The second is to set the mounting substrate 1 on the surface plane of the target inner wall as shown in FIG. 10 , and an angle γ is formed between the mounting substrate 1 and the cleaning rod 2 at this time.

It can be seen from FIG. 9 and FIG. 10 that when the support device 5 drives the mounting substrate 1 to move along the target inner wall surface (to the left near the corner), the leftmost group of cleaning rods 2 first touches the corner and is limited. , Specifically regarding the structure of the cleaning rod 2, each cleaning rod 2 includes a rod body 21 and a brush head seat 23; an installation groove is opened at one end of the rod body 21, and a pressure sensor 22 is fixed in the installation groove, and the driving device 3 responds The drive is performed according to the pressure change of the pressure sensor 22 ; the brush head seat 23 is used to install the soft brush head, and the end of the brush head seat 23 away from the soft brush head is embedded in the installation groove and between the pressure sensor 22 Connect the limit spring 24 . It can be seen from this that when the leftmost group of cleaning rods 2 (movable rods) are limited by the corners, the soft-bristle brush head and the brush head seat 23 squeeze the limit spring 24 due to the limit, and the limit spring 24 is squeezed and deformed to increase the pressure of the pressure sensor 22, thereby causing the pressure change of the overall cleaning rod 2. Correspondingly, the driving device 3 performs driving in response to the pressure change of the pressure sensor 22, thereby driving the leftmost A set of cleaning rods 2 on the side is moved back. With reference to the figure, the return distance of the leftmost group of cleaning rods 2 is: when the second left group of cleaning rods 2 is limited to the corner, the front end of the leftmost group of cleaning rods 2 just touches the rear of the corner. target inner wall. When the fixing rod on the mounting base 1 moves to the corner, the moving direction of the mounting base 1 is changed. At this time, the mounting base 1 moves down away from the corner. During the downward movement, the cleaning rod 2 (movable) on the right side of the fixing rod The rod) is separated from the target inner wall, so the pressure of the corresponding pressure sensor 22 suddenly changes to 0. At this time, the driving device 3 performs driving in response to the pressure change of the pressure sensor 22, thereby driving the cleaning rod 2 on the right side of the fixed rod. Protrude to the cleaning front and contact the inner wall of the target to complete the deformation cleaning at the corner.

For the above two embodiments, in the specific implementation of the present invention, regarding the driving of the cleaning rod 2: one side of the movable rod is set to have a continuous tooth slot structure, and the driving device 3 is set to include N rotatable toothed rollers 31 , and the toothed roller 31 meshes with the toothed side of the movable rod in one-to-one correspondence.
