[0018] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0019] like Figure 1 , 2 As shown, a detection box cleaning mechanism of a urine protein analyzer is used to be installed on the urine protein analyzer to clean the detection box on the urine protein analyzer. The urine protein analyzer includes a machine and a controller. A detection mechanism is arranged on the machine, and a detection box is arranged on the detection mechanism. The detection box cleaning mechanism includes a cleaning mounting frame 1, which is fixedly mounted on the machine. A cleaning motor 2 is fixedly mounted on the cleaning mounting frame 1. The cleaning motor 2 is electrically connected to the controller. A cleaning driving wheel 3 is arranged on the output end of the cleaning motor 2. The cleaning motor 2 can drive the cleaning driving wheel 3 to rotate on the cleaning mounting frame 1. A cleaning lifting rod 4 is eccentrically arranged on the side surface of the cleaning driving wheel 3; the cleaning driving wheel 3 is driven to rotate by the cleaning motor 2, thereby driving the cleaning lifting rod 4 to rise and fall. The cleaning mounting frame 1 is also provided with a cleaning lifting guide rail 5, on which a cleaning head mounting frame 6 is slidably provided, on which a plurality of cleaning needle tubes 7 are provided, and the cleaning needle tubes 7 are externally connected to a cleaning liquid, and the cleaning head mounting frame 6 is connected to a cleaning lifting rod 4, and the cleaning lifting rod 4 can push the cleaning head mounting frame 6 to move upward on the cleaning lifting guide rail 5.

[0020] In the initial state, the cleaning needle tube 7 is located directly above the test box. When the test box needs to be cleaned, the cleaning motor 2 is controlled to work, the cleaning drive wheel 3 is driven to rotate, and the cleaning lifting rod 4 is driven to move downward, so that it is separated from the cleaning head mounting frame 6; then the cleaning head mounting frame 6 will slide downward along the cleaning lifting guide rail 5 under the action of its own gravity; the cleaning needle tube 7 will simultaneously descend until the cleaning needle tube 7 is inserted into the test box, and then the test box is cleaned with an external cleaning liquid. After the cleaning is completed, the cleaning motor 2 is controlled to reverse, and the cleaning drive wheel 3 is driven to rotate in the opposite direction, driving the cleaning lifting rod 4 to move upward; at this time, the cleaning lifting rod 4 will push the cleaning head mounting frame 6 to move upward on the cleaning lifting guide rail 5; the cleaning needle tube 7 will synchronously rise until the cleaning needle tube 7 extends out of the test box and resets to the initial position.

[0021] Specifically, a cleaning lifting slider 8 is provided on the cleaning head mounting frame 6, and the cleaning lifting slider 8 is slidably engaged with the cleaning lifting guide rail 5. Through the cooperation of the cleaning lifting slider 8 and the cleaning lifting guide rail 5, the movement direction of the cleaning head mounting frame 6 can be limited and guided, thereby ensuring that the cleaning head mounting frame 6 can drive the cleaning needle tube 7 to be inserted into the detection box, thereby improving the transmission accuracy.

[0022] A cleaning push block 9 is provided on the cleaning head mounting frame 6, and a rotating bearing 10 is sleeved on the cleaning lifting rod 4. The rotating bearing 10 is connected to the cleaning push block 9, and the two are slidably matched. When the cleaning motor 2 and the cleaning lifting rod 4 rise, the rotating bearing 10 will slide on the cleaning push block 9, thereby pushing the cleaning head mounting frame 6 to rise; when the cleaning motor 2 rotates forward, the cleaning head mounting frame 6 falls due to its own gravity, which will push the rotating bearing 10 to rotate on the cleaning lifting rod 4. Through the cooperation of the rotating bearing 10 and the cleaning pushing block 9, the resistance of the cleaning head mounting frame 6 during the lifting and lowering movement can be reduced, thereby improving the stability and accuracy of the transmission.

[0023] A limit block 11 is provided at one end of the cleaning push block 9. When the cleaning lifting rod 4 pushes the cleaning head mounting frame 6 to rise to the initial position, or when the cleaning head mounting frame 6 is lowered to the limit position, the limit block 11 can abut against the rotating bearing 10. By providing the limit block 11, the movement stroke of the cleaning head mounting frame 6 can be limited, thereby improving the accuracy and stability of the transmission. In specific operation, when the limit block 11 abuts against the rotating bearing 10, the cleaning motor 2 will stop working immediately, thereby ensuring that the cleaning head mounting frame 6 can move to the preset position.

[0024] In order to improve the accuracy of control, a cleaning sensor 12 is provided on the cleaning mounting frame 1, and the cleaning sensor 12 is connected to the controller. Two cleaning induction paddles 13 are provided on the cleaning driving wheel 3, and the two cleaning induction paddles 13 can be connected to the cleaning sensor 12. In the initial state, one of the cleaning induction paddles 13 is connected to the cleaning sensor 12. When the cleaning motor 2 works to drive the cleaning driving wheel 3 to rotate, and then drives the cleaning lifting rod 4 to drop to the limit position, the other cleaning induction paddle 13 is connected to the cleaning sensor 12, and the cleaning sensor 12 feeds back a signal to the controller to control the cleaning motor 2 to stop working. At this time, the cleaning needle 7 just drops and is inserted into the detection box. When the cleaning motor 2 reverses to drive the cleaning driving wheel 3 to rotate in the opposite direction, and then drives the cleaning lifting rod 4 to push the cleaning head mounting frame 6 to rise to the initial position, the cleaning induction paddle 13 at the initial position just connects with the cleaning sensor 12, so that the feedback signal controls the cleaning motor 2 to stop working. Through the cooperation of the cleaning sensor 12 and the two cleaning sensing paddles 13, the movement stroke of the cleaning head mounting bracket 6 can be accurately controlled, thereby improving the transmission accuracy and processing stability.

[0025] The detection box cleaning mechanism also includes an auxiliary descending mechanism, which is used to provide auxiliary driving force during the free descent of the cleaning head mounting frame 6; thereby driving the cleaning head mounting frame 6 to move downward on the cleaning lifting guide rail 5. Specifically, the auxiliary descending mechanism includes an auxiliary spring 14, and the two ends of the auxiliary spring 14 are respectively connected to the cleaning head mounting frame 6 and the cleaning mounting frame 1. During operation, when the cleaning motor 2 reverses to drive the cleaning drive wheel 3 to rotate, and the cleaning head mounting frame 6 is pushed up by the cleaning lifting rod 4, the cleaning head mounting frame 6 will rise and pull up the auxiliary spring 14, thereby accumulating elastic potential energy. When the cleaning motor 2 rotates forward, the cleaning lifting rod 4 is separated from the limit of the cleaning head mounting frame 6, and the cleaning head mounting frame 6 is lowered by its own gravity. At the same time, the auxiliary spring 14 will also release elastic potential energy, thereby pulling the cleaning head mounting frame 6 down on the cleaning lifting guide rail 5. The auxiliary spring 14 can not only provide auxiliary driving force, but also eliminate the assembly gap between the cleaning push block 9 and the rotating bearing 10, thereby improving the compactness of the assembly; thereby reducing the sound emitted during transmission and achieving the effect of noise reduction.

[0026] In this embodiment, there are four cleaning needle tubes 7, and the four cleaning needle tubes 7 are detachably connected to the cleaning head mounting frame 6, so that the cleaning needle tubes 7 of the detection box cleaning mechanism can be replaced when necessary, thereby improving practicality.

[0027] Working principle:

[0028] In the initial state, the cleaning needle tube 7 is located directly above the detection box, the auxiliary spring 14 is in the pulled-up state, and one of the cleaning sensor paddles 13 is connected to the cleaning sensor 12. When the detection box needs to be cleaned, the cleaning motor 2 is controlled to work, the cleaning drive wheel 3 is driven to rotate, and the cleaning lifting rod 4 is driven to move downward, and the rotating bearing 10 will slide on the cleaning push block 9; at this time, the cleaning head mounting frame 6 and the cleaning needle tube 7 are affected by their own gravity and the elastic force of the auxiliary spring 14, and the cleaning head mounting frame 6 will slide downward on the cleaning guide rail; until the other cleaning sensor paddle 13 is connected to the cleaning sensor 12, at this time, the cleaning needle tube 7 is also inserted into the detection box, and then the detection box is cleaned by the external cleaning liquid.

[0029] After cleaning is completed, the cleaning motor 2 is controlled to reverse, drive the cleaning drive wheel 3 to rotate in the opposite direction, and drive the cleaning lifting rod 4 to move upward; the rotating bearing 10 slides on the cleaning push block 9, and pushes the cleaning push block 9 and the cleaning head mounting frame 6 to move upward on the cleaning lifting guide rail 5; the cleaning needle tube 7 rises synchronously until the cleaning sensing paddle 13 in the initial state is connected with the cleaning sensor 12, and then the cleaning motor 2 is controlled to stop working; at this time, the cleaning needle tube 7 also just extends out of the detection box and resets to the initial position.

[0030] The above-mentioned specific implementation mode is a preferred implementation mode of the present utility model, and is not intended to limit the specific implementation scope of the present utility model. The scope of the present utility model includes but is not limited to the specific implementation mode. All equivalent changes made in accordance with the present utility model are within the protection scope of the present utility model.
