Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1-3 The present invention provides a brush head transmission mechanism, which includes: a base 1, the base 1 being fixedly mounted on the mounting frame 100 of the intelligent toilet cleaning device, and a robotic arm 2 being mounted on the base 1. The robotic arm 2 includes a support column 3, a first transmission component 4, and a second transmission component 5. The first transmission component 4 is fixedly mounted on the support column 3 and is connected to the second transmission component 5. The second transmission component 5 is connected to a drive mechanism 6, which together constitute the robotic arm 2. The robotic arm 2 can achieve multi-dimensional movement, thereby enabling the removal of the cleaning brush to clean the toilet seat.

[0020] Specifically, after the device starts the cleaning program, the first transmission component 4 outputs power, which further drives the second transmission component 5 to move, thereby realizing the multi-dimensional movement of the robotic arm. After the robotic arm moves to the appropriate position, the further drive mechanism 6 contacts the cleaning brush and lifts it. The third drive part 63 on the drive mechanism 6 firmly grasps the cleaning brush head, and finally drives the cleaning brush to clean the toilet seat.

[0021] After cleaning the toilet seat, the drive mechanism 6 sends the unclean cleaning brush to the recycling bin. The drive mechanism 6 then throws the cleaning brush away and presses the flush switch on the toilet seat to complete the flush.

[0022] Please continue reading. Figure 1-5 In a preferred embodiment, the first transmission component 4 includes a fixed base 41, which is fixedly mounted on the top of the support column 3. A first motor 42 is mounted on the fixed base 41, and a first arm 43 is connected to the fixed base 41 through the first motor 42. The tail end of the first arm 43 is connected to the second transmission component 5.

[0023] Preferably, a fixed bracket 31 is provided on one side of the support column 3, and an image acquisition unit 32 is fixedly connected to the front side of the fixed bracket 31. Of course, the image acquisition unit 32 is electrically connected to the main control system of the device, so as to obtain the cleaning progress of the toilet seat in real time. At the same time, a circuit connection hole is provided on the left side of the first motor 42, and the connection hole is used to install the motor and other device wires.

[0024] In this process, when the first motor 42 is activated, it drives the first arm 43 to rotate, which in turn drives the second transmission component 5 to rotate, thereby realizing the first stage of motion of the robotic arm 2.

[0025] Please continue reading. Figure 1-5 The second transmission assembly 5 includes a second motor 51 and a second arm 52. The first arm 43 on the first transmission assembly 4 is connected to the second arm 52 via the second motor 51. When the second motor 51 moves, it drives the drive mechanism 6 to move, thereby realizing the second stage of movement of the robotic arm 2.

[0026] In the above scheme, the drive mechanism 6 includes a first drive unit 61, a second drive unit 62 and a third drive unit 63.

[0027] Specifically, the first drive unit 61 is fixedly mounted on the second arm 52. The first drive unit 61 includes a third motor 611, the bottom of which is fixedly mounted on the second arm 52. The output shaft 612 of the third motor 52 is connected to a belt 613, and the belt 613 is connected to a drive bearing 614, which is used to connect to the threaded rod 66. When the third motor 611 operates, the belt 613 transmits the first stage of rotational power to the threaded rod 66.

[0028] Specifically, the second drive unit 62 includes a fourth motor 621, which is connected to a transmission bearing 623 via a reduction shaft 622. The transmission bearing 623 is used to drive the threaded rod 66. When the fourth motor 621 operates, it can transmit the second stage of rotational power to the threaded rod 66. The first drive unit 61 and the second drive unit 62 work together to stabilize the power output of the threaded rod 66, making the operation smoother.

[0029] Specifically, the drive mechanism 6 also includes a third drive unit 63, which includes a lead screw drive shaft seat 631 and a lead screw nut seat 632. The lead screw drive shaft seat 631 is connected to the drive bearing 614 for transmission and is used to support the threaded rod 66. When the threaded rod 66 is connected, the lead screw nut seat 632 is provided. Under the joint action, the threaded rod 66 is driven to achieve the vertical movement.

[0030] Based on the above scheme, preferably, the drive mechanism 6 further includes a fixing part 64, which includes multiple fixing posts 641. The multiple fixing posts 641 are fixed to the second arm 52, and the top of the multiple fixing posts 641 is fixedly connected to the same top seat 642. The fixing part 64 is used to stabilize the threaded rod 66, so that the robotic arm 2 is more stable when driving the cleaning brush to clean the toilet seat.

[0031] Based on the above scheme, preferably, the drive mechanism 6 also includes an extraction part 65, which is fixedly disposed at the bottom end of the threaded rod 66. The extraction part 65 is used to extract the cleaning brush and press the flush switch on the toilet seat.

[0032] Preferably, the extraction unit 65 can be configured as a single-dimensional, two-dimensional, or three-dimensional motion structure. When configured as a single-dimensional direction, the extraction unit 65 is configured as a single-axis structure; when configured as a two-dimensional direction, the extraction unit 65 is configured as a two-axis or universal joint structure; when configured as a three-dimensional direction, it can be configured as a structure connected by multiple universal joints. Of course, the specific shape of the extraction unit 65 can be set according to more practical application scenarios.

[0033] In this invention, the first transmission component 4 and the second transmission component 5 together form the motion joint of the robotic arm 2. At the same time, a drive mechanism 6 is set on the second arm 52 of the second transmission component 5. The drive mechanism 6 can pick up the cleaning brush and clean the toilet seat. After cleaning, the unclean cleaning brush is placed in the recycling box. After detaching from the cleaning brush, the extraction part 65 on the drive mechanism 6 presses the flush switch on the toilet seat, which greatly improves the efficiency and stability of the device when cleaning the toilet seat. Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
