Further, the inner wall of the installation groove 11 is provided with two positioning bosses 13, and the outer ends of the opening and closing member 3 are provided with positioning grooves 32 that are matched with the positioning bosses 13, when the opening and closing member 3 When in the first position or the second position, one of the positioning grooves 32 can be matched with one of the positioning bosses 13, so that the opening and closing member 3 can be maintained in the first position or the second position.

The outer side wall of the mounting groove 11 corresponds to the outer contour of the cleaning tank 12 with a positioning recessed groove 14 formed, and the operating portion 52 is embedded in the positioning recessed groove 14, and the sliding movement of the operating lever 5 is more stable when the operating lever 5 is operated.

Of course, in addition to the above-mentioned embodiments, the opening and closing member can also adopt other methods. As shown in FIGS. 3 has a ring structure and can be rotatably sleeved outside the fuselage 1, which is axially limited by a limiting convex ring formed by the inner ring of the upper end and the fuselage 1, the cutter head assembly 2, on the opening and closing part 3 There are two through grooves 33 adapted to the cleaning tank 12. When the opening and closing member 3 is in the first position, the cleaning tank 12 and the through groove 33 are arranged in a staggered manner, so as to realize the closing of the cleaning tank. When 3 is in the second position, the cleaning tank 12 and the through tank 33 overlap, so as to realize the opening of the cleaning tank.

Wherein, a positioning boss 13 is provided on the outer side wall of the fuselage 1, and a positioning groove 32 adapted to the positioning boss 13 is provided on the inner side of the opening and closing member 3. When the opening and closing member 3 is in the first position or In the second position, the positioning groove 32 can be matched with one of the positioning bosses 13, so that the opening and closing member 3 can be maintained in the first position or the second position.

As shown in Figure 8, an annular side wall 221 is formed on the outer edge of the movable knife holder 22, and a plurality of spiral guide portions 222 are formed on the outer side of the annular side wall 221. When the motor is turned on when cleaning, the rotating shaft can drive The knife holder 22 rotates, and the movable knife holder 22 causes the water flow to form a vortex through the spiral guide portion 222 to achieve more effective cleaning.

A water outlet guide 4 is also formed in the installation tank 11 at a position corresponding to the cleaning tank 12. The outlet guide 4 can be fixed and formed in the installation tank 11 as shown in FIG. 11, or as shown in FIGS. 3 and 6. As shown, the outlet guide 4 and the opening and closing part 3 are arranged in an integrated structure, and the water flow can be further guided by the outlet guide 4. When the movable knife bracket 22 rotates to form a vortex, the water flow passes through the outlet guide 4 The water can be ejected from the cleaning tank 12 quickly. During the cleaning process, the cleaning water can be quickly sucked from the knife net, and at the same time, the cleaning water can be discharged from the cleaning tank 12 through the water outlet guide 4 to form A more reliable water circulation, further ensuring that the cleaning is fast and effective.
