[0035] Second Embodiment
[0036] Please refer to the following: Figure 3-4Based on the automated quantitative dispensing device for laboratories provided in the first embodiment of this application, the second embodiment of this application proposes another automated quantitative dispensing device for laboratories. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.
[0037] Specifically, the difference in the laboratory automatic quantitative dispensing device provided in the second embodiment of this application is that it also includes an installation groove 18, the water storage tank 5 is installed inside the installation groove 18, the water storage tank 5 is provided with a cover plate 19, the water storage tank 5 is provided with a first interface 20 and a second interface 21, the first interface 20 is connected to the water inlet 7, the second interface 21 is connected to the connecting pipe 15, and a fixing component 22 is installed on the body 1.
[0038] The fixing component 22 includes a fixing sleeve 221, a sliding block 222 is slidably connected inside the fixing sleeve 221, a return spring 223 is installed between the sliding block 222 and the inner wall of the fixing sleeve 221, a lever 224 is fixedly connected to one side of the sliding block 222, the lever 224 passes through the fixing sleeve 221 and extends to the outside of the fixing sleeve 221, and a limit block 225 is fixedly connected to the sliding block 222, the limit block 225 abuts against one side of the water storage tank 5.
[0039] The top of the mounting groove 18 is provided with a positioning groove 23, and the top of the cover plate 19 is provided with a positioning strip 24.
[0040] The positioning groove 23 and positioning strip 24 facilitate the positioning of the water storage tank 5, indirectly making the first interface 20 more accurately connected to the water inlet 7 and the second interface 21 more accurately connected to the connecting pipe 15.
[0041] Compared with related technologies, the automated quantitative dispensing device for laboratories provided by this utility model has the following advantages:
[0042] Beneficial effects:
[0043] After prolonged use, the water tank 5 can be manually moved upwards by pushing the lever 224, causing the sliding block 222 to move the limiting block 225 upwards, thus removing the obstruction on the left side of the water tank 5. This allows the water tank 5 to be pulled out to the left, separating the first interface 20 from the inlet 7 and the second interface 21 from the connecting pipe 15. This facilitates the disassembly of the water tank 5 and prevents water stains from settling inside after long-term use, thus avoiding any impact on the heating effect. After cleaning, simply push the water tank 5 into the mounting slot 18, connecting the first interface 20 to the inlet 7 and the second interface 21 to the connecting pipe 15, thus simplifying installation.
