Description

Technical Field

[0001] This utility model relates to the field of water sample dilution technology, and more specifically, to a fully automatic water sample dilution device. Background Technology

[0002] When testing water samples, high-concentration samples generally need to be diluted. During dilution, the ratio of purified water to the water sample needs to be determined based on the substances to be tested. This dilution alters the internal liquid concentration of the water sample, allowing for the analysis of water components at different concentrations to ensure accurate testing. The selection of the dilution factor, i.e., the determination of the sample volume, is crucial. Currently, water sample dilution is mainly performed manually. Manual operation is inefficient and lacks precision. Furthermore, when multiple test tubes are diluted manually simultaneously, cross-contamination between different tubes can occur. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a fully automatic water sample dilution device.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a fully automatic water sample dilution device, comprising: a base, a reducer, a test tube holder, a cleaning tube, a distilled water cup, and a dosing needle. Two sets of bases are arranged side-by-side. A reducer is mounted on the upper part of the base via a reducer bracket. The test tube holder is mounted on the reducer. The test tube holder consists of an upper test tube tray and a lower test tube tray, and several sets of test tube bodies are arranged on the test tube holder.

The test tube body passes through the through holes on the upper test tube tray, and its bottom is located in the countersunk hole of the lower test tube tray.

[0006] As a preferred technical solution of this utility model, the upper test tube tray and the lower test tube tray are fixedly connected by a connecting rod, which is vertically arranged and has multiple rods arranged in a ring array.

[0013] 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.

[0014] like Figures 1 to 2 As shown, this utility model provides a fully automatic water sample dilution device, including: a base 1, a reducer 3, a test tube support, a cleaning tube 9, a distilled water cup 14, and a dosing needle 17. The base 1 has two sets arranged side by side. The reducer 3 is installed on the upper part of the base 1 through a reducer bracket 2. The test tube support is installed on the reducer 3. The test tube support consists of an upper test tube tray 4 and a lower test tube tray 5. Several sets of test tube bodies 7 are arranged on the test tube support. The cleaning tube 9 and the distilled water cup 14 are arranged on the side of the base 1. The dosing needle 17 is installed on the lower part of one end of a swing arm 16. The other end of the swing arm 16 is installed on an adjusting rod 15. The adjusting rod 15 is installed on the swing arm motor.

[0015] Two sets of bases 1 correspond to two working areas, which can be distinguished as Area A and Area B in actual use. Area A contains test tubes 7 filled with water samples, while Area B contains empty test tubes. The cleaning tube 9 is used to clean the dosing needle 17. The dosing needle 17 first draws water from the distilled water cup 14 according to the dilution ratio and adds it to the test tube in Area B. Then, it draws water samples from test tubes 7 in Area A and adds them to the corresponding test tubes in Area B. Each water sample must be cleaned before drawing to avoid cross-contamination. When adding the water sample to the test tube in Area B, the water sample and distilled water are simultaneously drawn into the dosing needle 17 and then discharged to complete the mixing process. The reducer 3 can drive the entire test tube support to rotate, thereby changing the position of the test tubes 7 placed on the support to cooperate with the operation of the dosing needle 17.

[0016] The upper test tube tray 4 and the lower test tube tray 5 are circular structures of the same size. The upper test tube tray 4 has several sets of through holes arranged in a ring array, and the lower test tube tray 5 has corresponding countersunk holes, which are located directly below the through holes. The test tube body 7 passes through the through holes on the upper test tube tray 4, and its bottom is set in the countersunk hole of the lower test tube tray 5. The upper test tube tray 4 and the lower test tube tray 5 are fixedly connected by connecting rods 6, which are vertically arranged and have multiple members arranged in a ring array.

[0017] When placed, the test tube body 7 passes through the through hole on the upper test tube tray 4 and is set in the countersunk hole of the lower test tube tray 5, which can stably restrict the test tube and ensure its stability during use.

[0018] The cleaning pipe 9 is installed on the cleaning bracket 8, and an inner pipe 10 is installed inside the cleaning pipe 9. The top of the inner pipe 10 is lower than the top of the cleaning pipe 9, and a water inlet 12 is provided horizontally at the bottom of the inner pipe 10, and a drain outlet 11 is provided horizontally at the bottom of the cleaning pipe 9.

[0019] The inner tube 10 is connected to the water inlet 12, and the cleaning tube 9 is connected to the drain outlet 11. The dosing needle 17 moves up to the inner tube 10 and then moves down to insert into the inner tube 10. The cleaning water enters the inner tube 10 from the water inlet 12. Since the inner tube 10 is lower than the cleaning tube 9, the cleaning water overflows into the cleaning tube 9 and is discharged from the drain outlet 11, thus completing the cleaning process.

[0020] The distillation cup 14 is mounted on the distillation support 13. The dosing needle 17 is strip-shaped with an open bottom. A liquid pump is connected to the top of the dosing needle 17 via a pipette. The adjusting rod 15 is an electric push rod.

[0021] A liquid pump is used to assist the dosing needle 17 in liquid extraction. The adjusting rod 15, made of an electric push rod, can extend and retract to meet the needs of the dosing needle 17 moving up and down. The dosing needle 17 is driven to rotate by a swing arm motor.
