[0030] A pH-adjustable bacterial culture device comprises a culture tank 2 provided with a closed cover 1, and further comprising:

[0031] The temperature control base 4 is arranged below the culture tank 2 and is used to adjust the bacterial culture temperature. Figure 2 As shown, a cavity filled with a heat preservation liquid is provided inside, and an electric heating wire is provided in the cavity; a heat preservation cushion layer 6 is provided between the temperature control base 4 and the culture tank 2, which can improve the heat preservation effect.

[0032] The illumination ring 5 is arranged on the temperature control base 4 and sleeved on the body of the culture tank 2 to provide illumination for bacterial culture.

[0033] The two regulating units 7 include a regulating liquid tank 71 for containing acidic or alkaline pH regulating liquid, and the regulating liquid tank 71 is connected to the culture tank 2 through an infusion tube 78; a liquid pressing plate 73 is provided in the regulating liquid tank 71, which is vertically raised and lowered along the inner wall of the regulating liquid tank 71, and the liquid pressing plate 73 is used to press the pH regulating liquid into the regulating liquid tank 71.

[0034] When culturing bacteria, Figure 1In the structure shown, the pH of the culture solution will change during the bacterial culture process. In order to maintain a good culture environment, it is necessary to control the light, temperature, and pH value. In this embodiment, a branch pipe 21 is provided on the body of the culture tank 2, and a slot 211 for inserting a pH test probe 3 is provided on the branch pipe 21. When the pH of the culture solution needs to be tested, the pH test probe 3 can be inserted for testing, and when no test is required, the pH test probe 3 can be separated from the culture solution. An acidic or alkaline regulating liquid is selected according to the pH value, and the liquid pressing plate 73 is pressed down to squeeze the regulating liquid into the culture tank 2.

[0035] like Figure 4 and Figure 5 In the structure shown, a vertical cylinder 72 is installed above the regulating liquid tank 71, and a threaded rod 76 is rotatably installed in the vertical cylinder 72. The threaded rod 76 is threadedly installed on the vertical rod 74, and the vertical rod 74 is connected to the liquid pressure plate 73. In this embodiment, a hand wheel 77 is installed on the threaded rod 76. The hand wheel 77 can be rotated to drive the threaded rod 76 to rotate, and then the threaded vertical rod 74 is moved. In order to maintain the stability of the screw rod movement, a tension spring 75 is installed in the vertical cylinder 72 to connect the vertical rod 74.

[0036] Rubber sealing strips are provided at the corresponding positions of the liquid pressing plate 73 and the inner wall of the regulating liquid tank 71 to improve the sealing performance and prevent a large amount of regulating liquid from overflowing upward into the regulating liquid tank 71 located above the liquid pressing plate 73 during the downward pressure process, so that the regulating liquid is squeezed into the culture tank 2.

[0037] In this embodiment, a flow guide tube 22 is provided on the culture tank 2, and the flow guide tube 22 is connected to the infusion tube 78 through a connecting hose 79; Figure 3 In the structure shown, the inner end of the guide tube 22 of this embodiment is protrudingly arranged inside the culture tank 2 to prevent the regulating liquid from adhering to and remaining on the inner wall of the culture tank 2, so that the regulating liquid directly falls into the culture liquid below to obtain a uniform regulating effect.
