Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] like Figure 1-3 As shown, the utility model proposes a multifunctional constant temperature water bath device, including a multifunctional base, a water bathtub 4 and a test tube positioning assembly 9, the water bathtub 4 is installed on the multifunctional base, the test tube positioning assembly 9 is disassembled and installed on the water bathtub 4, the multifunctional base includes an integral support base 1, a rotating motor 3 and a temperature raising ring 2, the rotating motor 3 is installed in the integral support base 1, the temperature raising ring 2 is arranged on the outer side of the integral support base 1, the test tube positioning assembly 9 includes a support plate 10 and a test tube storage assembly, the support plate 10 is disassembled and installed on the water bathtub 4, the test tube storage assembly is arranged on the support plate 10, and the water bathtub 4 is installed on the output shaft of the rotating motor 3.

[0023] In order to ensure the constant temperature effect, the water bathtub 4 is also provided with a temperature control device, which includes a temperature control setter 7 and a temperature sensor 8. The temperature control setter 7 and the temperature sensor 8 are respectively arranged on the side walls of the water bathtub 4, and a cooling plate 5 is arranged on the inner wall of the water bathtub 4.

[0024] In order to reduce temperature loss and water splashing when using the centrifugal function, the water bathtub 4 is provided with an annular supporting sealing splash-proof ring 6, and the supporting plate 10 is detachably arranged on the supporting sealing splash-proof ring 6. For ventilation, the supporting plate 10 is also provided with convection outlet holes 11.

[0025] In order to fix and place the test tubes that need to be treated in a water bath, the test tube positioning assembly 9 includes a water-proof limit sleeve 14 and a limit assembly. Placement holes 12 are evenly arranged on 10, and the water-proof limit sleeve 14 is installed on the lower side of the placement hole 12. The limit assembly is movably arranged on the side wall of the placement hole 12 and is provided with four groups. In order to fix test tubes of different specifications, the limit assembly includes an extrusion spring 13 and an extrusion protection pad 15.
