[0003] Patent CN221445850U discloses a sample delivery and cleaning device and a sample delivery and cleaning control system. When it is necessary to clean the spectrometer, the rotating device rotates the rotating support, so that the cleaning water tank moves to the bottom of the spectrometer's suction tube. The support lifting device drives the mounting support to move upward, so that the spectrometer's suction tube is inserted into the cleaning water tank for cleaning. After cleaning is completed, the support lifting device drives the cleaning water tank away from the suction tube.

[0004] However, the water in the aforementioned cleaning tank cannot be changed in a timely manner, which affects the cleaning effect. Utility Model Content

[0005] The purpose of this invention is to provide a cleaning device that can keep the water fresh in a timely manner.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cleaning device, comprising: Sample base plate; A lifting device, which is fixed to the sample delivery base plate; A clamping device, which is mounted on the lifting device; A cleaning pipe is provided with an outlet annular groove at its opening and an inlet groove on the cleaning pipe. The inlet groove is located inside the outlet annular groove, and the bottom of the outlet annular groove is lower than the opening of the inlet groove. A cleaning bracket is fixed on the sample delivery base plate. An inlet pipe and an outlet pipe are fixed on the cleaning bracket. The spectrometer's suction pipe is also fixed on the cleaning bracket. The clamping device is used to clamp the cleaning pipe. After the lifting device lifts the cleaning pipe, the lower ends of the inlet pipe and the spectrometer's suction pipe are inserted into the inlet groove. The lower end of the outlet pipe is inserted into the outlet ring groove. An inlet pump is connected to the upper end of the inlet pipe, and an outlet pump is connected to the upper end of the outlet pipe.

[0007] Furthermore, it also includes: A conveying device includes a first conveying pulley, a second conveying pulley, a conveyor belt, and a conveying drive motor. The first and second conveying pulleys are rotatably connected to the sample feeding base plate. The conveyor belt is connected between the first and second pulleys. The conveying drive motor is fixed to the sample feeding base plate, and the shaft of the conveying drive motor is fixedly connected to the first conveying pulley. A conveyor seat is fixed on the conveyor belt. The conveyor seat is provided with test tube slots with the opening facing upwards. Multiple conveyor seats are provided. One of the conveyor seats has a cleaning tube placed in its test tube slot, while the other conveyor seats have test tubes to be tested placed in their test tube slots.

[0008] Furthermore, the lifting device includes a lifting bracket and a lifting cylinder. The lifting bracket is fixed to the sample feeding base plate, the lifting cylinder is fixed to the lifting bracket, and the clamping device is fixed to the piston rod of the lifting cylinder.

[0009] Compared with the prior art, the beneficial effects of this utility model are: (1) The water pump draws pure water into the water tank through the water inlet pipe. When the water tank is full, it will overflow into the water outlet ring groove. At this time, the water pump draws the water out of the water outlet ring groove through the water outlet pipe. In this way, the water can keep flowing and will never overflow. The liquid suction tube of the spectrometer is always immersed in pure water and is not contaminated. (2) The sampling device places the test tube to be tested in the test tube slot of the conveyor seat. Then the conveyor drive motor drives the first conveyor pulley to drive the first conveyor pulley and the second conveyor pulley to drive the conveyor belt to rotate, thereby moving the test tube to the bottom of the spectrometer's suction tube. At this time, the lifting device drives the clamping device to move downward, and then the clamping device clamps the test tube. Then the lifting device drives the test tube to move upward, so that the spectrometer's suction tube is connected to the test tube, thereby allowing the liquid in the test tube to be detected. Since the first conveyor pulley, the second conveyor pulley and the conveyor belt are used, the position of the spectrometer can be better arranged. Even if the position of the sample delivery device is far from the spectrometer, the space occupied by the sampling device remains unchanged. Attached Figure Description

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0013] Please see Figures 1-4 This utility model provides a technical solution for a cleaning device.

[0014] A cleaning apparatus, comprising: Sample base plate 2; The lifting device is fixed on the sample delivery base plate 2; A clamping device is mounted on the lifting device; The cleaning pipe 11 has an outlet annular groove 12 at its opening and an inlet groove 13 on its surface. The inlet groove 13 is located inside the outlet annular groove 12, and the bottom of the outlet annular groove 12 is lower than the opening of the inlet groove 13. A cleaning bracket 14 is fixed on the sample delivery base plate 2. An inlet pipe 15 and an outlet pipe 16 are fixed on the cleaning bracket 14. The liquid suction pipe 10 of the spectrometer 9 is also fixed on the cleaning bracket 14. A clamping device is used to clamp the cleaning pipe 11. After the lifting device lifts the cleaning pipe 11, the lower ends of the inlet pipe 15 and the liquid suction pipe 10 of the spectrometer 9 are inserted into the inlet tank 13. The lower end of the outlet pipe 16 is inserted into the outlet ring groove 12. The upper end of the inlet pipe 15 is connected to an inlet pump, and the upper end of the outlet pipe 16 is connected to an outlet pump.

[0015] When the spectrometer 9 is not working or waiting, the lifting device raises the cleaning tube 11, and the lower ends of the water inlet pipe 15 and the liquid suction tube 10 of the spectrometer 9 are connected to the water inlet tank 13. The water pump draws pure water into the water inlet tank 13 through the water inlet pipe 15. When the water inlet tank 13 is full, it will overflow into the water outlet ring groove 12. At this time, the water outlet pump draws the water out of the water outlet ring groove 12 through the water outlet pipe 16. In this way, the water can keep flowing and will never overflow. The liquid suction tube 10 of the spectrometer 9 is always immersed in pure water and is not contaminated.

[0016] The cleaning device also includes: The conveying device includes a first conveying pulley 3, a second conveying pulley 4, a conveyor belt 5, and a conveying drive motor 6. The first conveying pulley 3 and the second conveying pulley 4 are rotatably connected to the sample feeding base plate 2. The conveyor belt 5 is connected between the first pulley and the second pulley. The conveying drive motor 6 is fixed to the sample feeding base plate 2, and the rotating shaft of the conveying drive motor 6 is fixedly connected to the first conveying pulley 3.

One of the test tube slots 8 of the conveyor seat 7 contains a cleaning tube 11, and the test tube slots 8 of the other conveyor seats 7 contain test tubes 22 to be tested.

[0017] The sampling device 21 places the test tube 22 to be tested into the test tube slot 8 of the conveyor seat 7. Then, the conveyor drive motor 6 drives the first conveyor pulley 3, which in turn drives the conveyor belt 5 to rotate, thereby moving the test tube 22 below the liquid absorption tube 10 of the spectrometer 9. At this time, the lifting device drives the clamping device to move downward, and then the clamping device picks up the test tube 22. Next, the lifting device moves the test tube 22 upward, so that the liquid absorption tube 10 of the spectrometer 9 is inserted into the test tube 22, thus allowing the liquid in the test tube 22 to be detected. Because of the conveying method using the first conveyor pulley 3, the second conveyor pulley 4, and the conveyor belt 5, the position of the spectrometer 9 can be better arranged. Even if the position of the sample delivery device 1 is far from the spectrometer 9, the space occupied by the sampling device 21 remains unchanged.
