[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1 In this embodiment, a cleaning brush head that is easily replaceable for a cleaning service robot includes a cleaning service robot body 1. The outer surface of the cleaning service robot body 1 is provided with a cleaning plate 2 for cleaning the floor. The outer surface of the cleaning plate 2 is provided with a mounting groove 3. The inner cavity of the mounting groove 3 is provided with a cleaning brush head body 4. The left and right ends of the inner cavity of the cleaning plate 2 are provided with a replacement mechanism 5 for facilitating the replacement of the cleaning brush head body 4. The left and right sides of the cleaning plate 2 are provided with a limiting mechanism 6 for limiting the position.

[0032] In this embodiment, the size of the inner cavity of the installation groove 3 is larger than the size of the cleaning brush head body 4 .

[0033] See also Figures 2 to 4In order to facilitate the replacement of the cleaning brush head body 4, the replacement mechanism 5 in this embodiment includes a fixed cavity 51, two threaded rods 52, two rotating gears 53, a driving rod 54, a movable plate 55, a triangular column 56 and a positioning block 57. The fixed cavity 51 is opened in the inner cavity of the cleaning plate 2, and the threaded rod 52 is rotatably connected between the opposite sides of the left and right side walls of the inner cavity of the fixed cavity 51 through a bearing. The rotating gear 53 is fixed to the left end of the outer surface of the threaded rod 52. The opposite sides of the upper left and right threaded rods 52 both penetrate the fixed cavity 51 and extend to the outside of the cleaning plate 2 and are connected to the driving plate 54. The rod 54 is fixed, and the driving rod 54 is rotated. The rotation of the driving rod 54 causes the upper threaded rod 52 to rotate. The rotation of the upper threaded rod 52 drives the upper rotating gear 53 to rotate, thereby causing the lower rotating gear 53 meshing with it to rotate, which can cause the lower threaded rod 52 to rotate. The movable plate 55 is threadedly connected to the two threaded rods 52. The rotation of the two threaded rods 52 causes the movable plate 55 threadedly connected to its surface to move. The triangular column 56 is fixed to the middle part of the movable plate 55 away from the rotating gear 53. The positioning block 57 is fixed to the outer surface of the cleaning brush head body 4.

[0034] Among them, the rotating gears 53 at the upper and lower ends are meshed and connected, the top and bottom between the opposite sides of the left and right side walls of the fixed cavity 51 are fixed with limit rods, the top and bottom of the movable plate 55 are fixed with limit plates, and the limit plate is slidably connected with the limit rod. Under the action of the limit rod and the limit plate, the movable plate 55 makes a linear motion, which can limit the movement of the movable plate 55.

[0035] In this embodiment, a handle is fixed on the side of the driving rod 54 away from the cleaning plate 2, and the two fixed cavities 51 are provided with a triangular hole adapted to the size of the triangular column 56 on the opposite sides, and the two positioning blocks 57 are provided with a triangular groove on the opposite sides, and the size of the inner cavity of the triangular groove is adapted to the size of the triangular column 56.

[0036] It should be noted that the opposite movement of the two movable plates 55 can drive the triangular column 56 to move out of the inner cavity of the triangular groove and move into the inner cavity of the fixed cavity 51 through the triangular hole. Then, the right end of the cleaning brush head body 4 can be released from the limit and the cleaning brush head body 4 can be taken out and replaced.

[0037] See also Figure 5In order to position the driving rod 54, the limiting mechanism 6 in this embodiment includes a positioning plate 61, a block 62, a connecting plate 63, two telescopic rods 64, two return springs 65 and an insertion rod 66. The positioning plate 61 is fixed to the outer surface of the cleaning plate 2, the block 62 is fixed to the bottom of one side of the positioning plate 61, the connecting plate 63 is arranged on the lower side of the block 62, the two telescopic rods 64 are fixed at the left and right ends between the block 62 and the opposite side of the connecting plate 63, the return spring 65 is movably sleeved on the outer surface of the telescopic rod 64, and the insertion rod 66 is fixed to the middle part of the upper surface of the connecting plate 63. After the cleaning brush head body 4 is replaced, the insertion rod 66 is located at the lower side of the driving rod 54, the return spring 65 and the telescopic rod 64 are both stretched, and then the limit of the connecting plate 63 is released, the return spring 65 rebounds and drives the telescopic rod 64 to shorten, so that the connecting plate 63 moves to the side close to the block 62, and the movement of the connecting plate 63 can drive the insertion rod 66 to move upward.

[0038] The driving rod 54 penetrates through the positioning plate 61 and extends to a side away from the positioning plate 61 and is rotatably connected to the positioning plate 61 via a bearing. The cross-sectional shape of the clamping block 62 is an inverted U shape.

[0039] In this embodiment, the two ends of the return spring 65 are respectively fixedly connected to the opposite side of the block 62 and the connecting plate 63, and the upper surface of the insertion rod 66 passes through the block 62 and extends to the upper side of the driving rod 54 until the insertion rod 66 enters the inner cavity of the driving rod 54, thereby limiting the driving rod 54.

[0040] It can be understood that positioning the driving rod 54 can prevent it from rotating due to collision or other reasons, thereby greatly improving the fixing stability of the cleaning brush head body 4.

[0041] The working principle of the above embodiment is:

[0042] (1) When replacing the cleaning brush head body 4 of the cleaning service robot body 1, the driving rod 54 can be rotated. The rotation of the driving rod 54 causes the upper threaded rod 52 to rotate, and the rotation of the upper threaded rod 52 drives the upper rotating gear 53 to rotate, thereby causing the lower rotating gear 53 meshing with it to rotate, which can cause the lower threaded rod 52 to rotate. The rotation of the two threaded rods 52 causes the movable plate 55 threadedly connected to its surface to move. Under the action of the limiting rod and the limiting plate, the movable plate 55 makes a linear motion. The opposite movement of the two movable plates 55 can drive the triangular column 56 to move out of the inner cavity of the triangular groove and move into the inner cavity of the fixed cavity 51 through the triangular hole. Then, the right end of the cleaning brush head body 4 is released from the limit so that the cleaning brush head body 4 can be taken out and replaced.

[0043] (2) In order to limit the driving rod 54 and prevent it from rotating and causing the cleaning brush head body 4 to be unstable, after the cleaning brush head body 4 is replaced, the insertion rod 66 is located at the lower side of the driving rod 54, the return spring 65 and the telescopic rod 64 are both stretched, and then the limit on the connecting plate 63 is released, the return spring 65 rebounds and drives the telescopic rod 64 to shorten, so that the connecting plate 63 moves to the side close to the block 62, and the movement of the connecting plate 63 can drive the insertion rod 66 to move upward until the insertion rod 66 enters the inner cavity of the driving rod 54, thereby limiting the driving rod 54.
