DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Refer to Figures 1-3 , a cleaning device for a gene detection detector, including a square frame 1 and a test tube 4. A rubber pad is fixedly connected to the lower end of the square frame 1 to increase the friction between the square frame 1 and the ground and enhance the overall stability. A storage box 2 is fixedly connected to the inner bottom of the square frame 1 for collecting waste water. An opening is provided at the upper end of the storage box 2. A drain pipe 5 communicating with the storage box 2 is fixedly inserted on the outer side wall of the square frame 1 and near the bottom for facilitating the user to drain waste water in cooperation with a valve. A valve is installed on the drain pipe 5;

[0022] In this embodiment, a plurality of connecting columns 3 are fixedly connected to the inner bottom of the storage box 2 for supporting the test tubes 4. The connecting columns 3 are made of rubber to prevent the test tubes 4 from being worn. The upper end of the connecting column 3 is provided with a slot corresponding to the test tube 4 for inserting and accommodating the test tube 4. The inner diameter of the slot is 0.5 - 0.1 CM smaller than the diameter of the test tube 4 for clamping the test tube 4. The lower end of the test tube 4 is slidably inserted into the slot. Two electric push rods 8 are fixedly inserted into the inner top of the square frame 1 for driving the lifting block 6 to lift and lower. The upper end of the electric push rod 8 penetrates through the square frame 1. A lifting block 6 is slidably connected to the inner side wall of the square frame 1 near the top for driving the second water pipe 7 to lift and lower. The lower end of the electric push rod 8 is fixedly connected to the upper end of the lifting block 6. A flow channel is provided near the top in the lifting block 6 for flowing cleaning water and high-pressure water into the second water pipe 7. The upper end of the lifting block 6 is fixedly connected to a first water pipe 9 communicating with the flow channel for communicating with an external high-pressure water source for water supply and water transmission. The first water pipe 9 is a telescopic hose to avoid affecting the lifting and lowering of the lifting block 6. The upper end of the first water pipe 9 penetrates through the square frame 1;

[0023] In this embodiment, a connecting groove is provided near the bottom in the lifting block 6. A plurality of second water pipes 7 corresponding to the connecting columns 3 are inserted into the inner top of the connecting groove for conveying water into the third water pipe 16. The second water pipes 7 are made of stainless steel for supporting the cleaning brush 15. The lower end of the second water pipe 7 is hermetically arranged. The second water pipes 7 are vertically arranged. The upper end of the second water pipe 7 penetrates through the lifting block 6 and extends into the flow channel. The lower end of the second water pipe 7 penetrates through the lifting block 6 and extends into the storage box 2. The second water pipe 7 is rotatably connected to the lifting block 6. Two first sealing rings 13 are rotatably sleeved on the second water pipe 7 for improving the sealing performance between the second water pipe 7 and the flow channel. The two first sealing rings 13 are respectively fixed on the inner top of the connecting groove and the inner bottom of the flow channel. Two second sealing rings 14 are rotatably sleeved on the second water pipe 7 for improving the sealing performance between the second water pipe 7 and the connecting groove. The two second sealing rings 14 are respectively fixed on the inner bottom of the connecting groove and the lower end of the lifting block 6;

[0024] In this embodiment, a plurality of third water pipes 16 are fixedly communicated with the outer side wall of the second water pipe 7 located outside the lifting block 6 for spraying cleaning water. A cleaning brush 15 is fixedly connected to one side of the second water pipe 7 close to the third water pipe 16 for cleaning the inner wall of the test tube 4. A servo motor 10 is fixedly connected to the inner side wall of the connection groove for driving the worm 11 to rotate. The end of the output shaft of the servo motor 10 is fixedly connected with a horizontally arranged worm 11 for driving the worm gear 12 to rotate. One end of the worm 11 away from the servo motor 10 is rotatably connected to the inner side wall of the connection groove. A worm gear 12 meshing with the worm 11 is fixedly sleeved on the second water pipe 7 for driving the second water pipe 7 to rotate.

[0025] In this embodiment, first, the first water pipe 9 is communicated with an external high-pressure water source, and then the electric push rod 8 is started to drive the lifting block 6 to descend (since the first water pipe 9 is a telescopic hose, it will not affect the lifting of the lifting block 6). The second water pipe 7 is driven by the lifting block 6 to be inserted into the test tube 4. At this time, the external high-pressure water source flows into the flow groove through the first water pipe 9, and then flows into the second water pipe 7 through the flow groove. Subsequently, it is sprayed on the inner side wall of the test tube 4 through the third water pipe 16 to perform a flushing operation. At the same time, the servo motor 10 is started to drive the worm 11 to rotate, and the second water pipe 7 is driven to rotate by the meshing of the worm 11 and the worm gear 12. The cleaning brush 15 is driven by the second water pipe 7 to perform a scrubbing operation on the inner side wall of the test tube 4, thereby improving the cleaning efficiency.

[0026] As mentioned above, the servo motor and the electric push rod are existing mature technologies, and their working principles and internal structures are known to those skilled in the art. This application only utilizes their functions and does not improve their internal structures. Therefore, no detailed description is given.

[0027] As mentioned above, the above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
