For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] Please refer to Figures 1 to 10 The embodiment of the utility model provides an installation and disassembly device for a roller brush 2 of a floor scrubber, comprising a machine head 1, a roller brush 2 arranged on the machine head 1, a sewage suction pipe 3 arranged in the machine head 1 and facing the roller brush 2, and also comprising a locking assembly 4 arranged in the machine head 1, and a rotating assembly 5 detachably installed in the locking assembly 4, wherein the roller brush 2 is arranged on the rotating assembly 5; the locking assembly 4 comprises a pressing member 41 arranged on the machine head 1, an elastic member 42 sleeved on the pressing member 41 and with the lower end pressed against the machine head 1, a fixed clamping member 43 fixed to the lower end of the pressing member 41, and a locking member 44 arranged between the fixed clamping member 43 and the pressing member 41, and the rotating assembly 5 comprises a hanging plate 51 that can be hooked on the locking member 44.

[0035] When the floor scrubber is in normal use, Figure 1 and Figures 4 to 5 As shown, the hook plate 51 is hooked on the locking member 44, thereby fixing the rotating assembly 5 on the machine head 1, thereby ensuring the normal operation of the roller brush 2 on the rotating assembly 5. The roller brush 2 scrubs the ground, and at the same time, the sewage suction pipe 3 is started to absorb and collect the garbage on the roller brush 2.

[0036] When it is necessary to clean the sewage suction pipe 3, Figures 2 to 3 as well as Figure 6 to Figure 7 As shown, it is only necessary to press the pressing member 41, which presses downward to deform the elastic member 42 and simultaneously drives the fixing clamp 43 and the locking member 44 arranged thereon to move downward. At this time, the position of the hanging plate 51 remains unchanged, and the locking member 44 moves downward, so that the hanging plate 51 is disengaged from the locking member 44, releasing the fixation of the hanging plate 51, so that the rotating component 5 can rotate freely on the side wall of the machine head 1, and the rotating component 5 is rotated to a position away from the machine head 1, so that the roller brush 2 leaves the position facing the sewage suction pipe 3, and the inlet of the sewage suction pipe 3 is exposed, so that the sewage suction pipe 3 can be cleaned to prevent the inlet of the sewage suction pipe 3 from being blocked. The whole operation is simple and convenient, and does not require professional operation by professionals, which is convenient for people to use.

[0037] When it is necessary to reset the rotating assembly 5 and the roller brush 2, Figure 1 and Figures 4 to 5 As shown, it is only necessary to press the pressing member 41 to deform the elastic member 42 and drive the fixed clamping member 43 and the locking member 44 disposed thereon to move downward, and rotate the rotating assembly 5 to a position close to the machine head 1. At this time, the hanging buckle plate 51 is embedded in the machine head 1 to complete the reset, and the pressing force on the pressing member 41 is released. The pressing member 41 moves upward under the elastic restoring force of the elastic member 42 itself, and drives the fixed clamping member 43 and the locking member 44 disposed thereon to move upward, so that the hanging buckle plate 51 is hooked on the locking member 44 that has moved upward, and the rotating assembly 5 and the roller brush 2 are fixed, and the floor scrubber can be used normally to clean the floor. Its disassembly and installation operations are simple and convenient.

[0038] Preferably, Fig. 9 As shown, the fixing clamp 43 is a screw whose top end penetrates into the lower end of the pressing member 41. It is cheap, durable, and easy to install, which effectively reduces the production cost of the device and improves the production efficiency of the device.

[0039] Preferably, Fig. 9 As shown, the elastic member 42 is a spring, which has a simple structure, low price, good fatigue resistance, and storage of deformation energy, and effectively provides power for the pressing member 41 to reset, thereby ensuring the tightening of the device and reducing the production cost of the device.

[0040] The specific method of locking the buckle plate 51 by the locking member 44 is as follows: Figure 5 , Figure 7 as well as Fig. 9 As shown, the locking member 44 includes a locking fixing plate 441 arranged between the fixed clamping member 43 and the pressing member 41, a locking recess 442 formed on the locking fixing plate 441 facing the rotating component 5 and matching the shape of the locking plate 51, and a locking step 443 formed on the locking recess 442; a locking hole 511 matching the locking step 443 is formed on the locking plate 51, and the locking fixing plate 441 is used to fix the locking member 44 between the fixed clamping member 43 and the pressing member 41, thereby realizing the driving effect of the pressing member 41. When it is necessary to lock the rotating component 5 on the locking component 4, the pressing piece 41 is released, and the pressing piece 41 moves upward under the elastic restoring force of the elastic piece 42, and the hook plate 51 is correspondingly embedded in the hook yielding groove 442, and the locking step 443 is embedded in the locking hole 511. At this time, the hook plate 51 cannot move horizontally and radially, thereby achieving the purpose of locking the hook plate 51 in the locking piece 44, and completing the locking of the rotating component 5.

[0041] Preferably, in order to make the locking step 443 better embedded in the locking hole 511, as shown in FIG. Figure 5 , Figure 7 as well as Fig. 9 As shown, the end of the locking step 443 facing the buckle plate 51 is formed with a first locking guide surface 4431 extending obliquely from the upper inner side to the lower outer side. When the locking step 443 is to be inserted into the locking hole 511, the first locking guide surface 4431 first contacts the inner wall of the locking hole 511. Under the guidance of the first locking guide surface 4431, the locking step 443 enters the locking hole 511 more easily and accurately, thereby effectively improving the efficiency and accuracy of the locking member 44 in locking the buckle plate 51.

[0042] Preferably, in order to better embed the buckle plate 51 into the buckle yielding groove 442, as shown in FIG. Figure 5 as well as Figure 8 As shown, a second locking guide surface 512 is formed on the outer side surface of the lower part of the buckle plate 51 and extends obliquely from the upper outer side toward the lower part of the lock hole 511. When the buckle plate 51 is to be inserted into the buckle clearance groove 442, the second locking guide surface 512 first contacts the inner wall of the buckle clearance groove 442. Under the guidance of the second locking guide surface 512, the lower part of the buckle plate 51 enters the buckle clearance groove 442 more easily and accurately, thereby effectively improving the efficiency and accuracy of the buckle member 44 in locking the buckle plate 51.

[0043] Regarding the specific structural arrangement of the pressing member 41 on the machine head 1, as shown in FIG. Fig.10 As shown, a downwardly recessed pressing groove 11 is formed on the side of the upper end surface of the head 1 facing the rotating component 5, and the pressing member 41 and the elastic member 42 move up and down in the pressing groove 11, and the lower end of the elastic member 42 presses against the lower end surface of the pressing groove 11, thereby providing a position for the elastic member 42 to press, which is convenient for the elastic member 42 to deform and provide an upward force, and can effectively limit the movable stroke of the pressing member 41 and the elastic member 42, so that the pressing member 41 and the elastic member 42 can only move vertically in the up and down directions, preventing the pressing member 41 and the elastic member 42 from shifting left and right, thereby improving the efficiency and accuracy of the pressing member 41 in driving the locking assembly 4, facilitating the coordination between the components, and facilitating people to clean the suction pipe 3.

[0044] Preferably, in order to make the locking member 44 more movable, as Fig.10As shown, a lock limit ring plate 12 matching the lock member 44 is also formed at the lower end of the pressing groove 11. The lock member 44 moves up and down in the lock limit ring plate 12, so that the movement stroke is limited by the lock limit ring plate 12 and can only perform vertical movement in the up and down directions, thereby preventing the lock member 44 from shifting left and right, resulting in the problem that the hanging plate 51 cannot be normally locked into the lock member 44, thereby improving the efficiency and accuracy of the lock member 44 in locking the rotating component 5, making the locking more secure.

[0045] Regarding the specific structural setting of the rotating assembly 5, as shown in FIG. Figures 2 to 3 , Figure 6 as well as Figure 8 The rotating assembly 5 shown in the figure also includes a rotating plate 52 rotatably arranged on the side of the machine head 1, the buckle plate 51 is arranged on the inner wall of the rotating plate 52, and the roller brush 2 is radially and vertically arranged on the outermost end of the inner wall of the rotating plate 52. The buckle plate 51 can be formed integrally on the rotating plate 52 to ensure the driving effect of the rotating plate 52 on the buckle plate 51. The end of the rotating plate 52 away from the roller brush 2 is rotatably arranged on the side of the machine head 1. When the sewage suction pipe 3 needs to be cleaned, the rotating plate 52 can be rotated outward with the connection with the side of the machine head 1 as the axis, thereby driving the roller brush 2 arranged thereon to drive outward, so as to leave the position directly opposite to the sewage suction pipe 3, and the sewage suction pipe 3 is exposed for easy cleaning.

[0046] The specific method of the buckle plate 51 extending into the machine head 1 and being locked by the locking member 44 is as follows: Figures 2 to 3 As shown in FIG. 7 , a rotating embedding groove 13 matching the rotating plate 52 is formed on the outer wall of the head 1, and a through groove 14 for the hook plate 51 to penetrate is formed on the rotating embedding groove 13. When the floor scrubber is used normally, the rotating plate 52 is embedded in the rotating embedding groove 13, thereby maintaining the neatness and beauty of the appearance of the floor scrubber, and the hook plate 51 passes through the through groove 14 into the head 1 and is locked by the locking member 44.

[0047] In order to prevent the hook plate 51 from being unable to pass through the through slot 14 and enter the machine head 1 by rotating along an inclined trajectory and being locked by the locking member 44, as shown in FIG. Figures 8 to 9 As shown, the buckle plate 51 is a fan-shaped structure with a wide front end and a narrow rear end, the locking member 44 is also a fan-shaped structure with a wide front end and a narrow rear end, and the buckle yielding groove 442 is also a fan-shaped structure with a wide front end and a narrow rear end that matches the buckle plate 51, so that the shape of the buckle plate 51 matches the shape of the arc trajectory of its rotation, thereby preventing the problem of the buckle plate 51 being unable to extend into the through groove 14 and be locked by the locking member 44 when being set as a long straight plate due to being driven to rotate in an arc.

[0048] It should be noted that the roller brush loading and unloading device for cleaning the sewage suction pipe disclosed in the utility model is an improvement on the specific structure, and the specific control method is not the innovation point of the utility model. The spring, sewage suction pipe, roller brush and other components involved in the utility model can be universal standard parts or components known to those skilled in the art, and their structures, principles and control methods are all known to those skilled in the art through technical manuals or conventional experimental methods.

[0049] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, other structures obtained by adopting the same or similar technical features as the above embodiments of the present invention are within the protection scope of the present invention.
