DETAILED DESCRIPTION

[0022] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0024] Figure 1-Figure 3 As an embodiment of the present utility model, a water bath 1 with a lifting test tube rack for students is disclosed in the patent document with application number CN201820756013.5. Although the water bath 1 in the comparative document can clamp and adjust the height of multiple test tubes at the same time, the water bath 1 cannot control the temperature and pressure of each reaction container individually according to the set temperature value and reaction time in the reaction container, and the lifting and placing of the reaction containers are not possible. Moreover, the driving parts are all arranged in the water bath environment, and there is a risk of rust between the moving parts, water ingress or jamming. Based on the above existing problems, the inventor has elaborated a constant temperature water bath device, which utilizes the setting of separating the water bath box 1 into a top box 11 and a bottom box 12, and sets the part for heating the water bath tube 3 in the bottom box 12, and the second-order rod 422 for controlling the lifting of the water bath tube 3 in the lifting component 4 is set in the top box 11 to avoid the contact of the second-order rod 422 with hot water. After the water bath tube 3 reaches a predetermined temperature, the lifting component 4 pushes the water bath tube 3 to the range of the top box 11, and releases the contact between the water bath tube 3 and the bottom box 12, thereby enhancing the temperature control of the liquid in the water bath tube 3.

[0025] A constant temperature water bath device described in this scheme specifically sets up a water bath box 1, and a box port 2 is set in the water bath box 1, which is connected to the inside of the water bath box 1, and a cover plate 6 is set on the box port 2. The cover plate 6 is composed of a plurality of cover rings, the diameters of the plurality of cover rings gradually decrease and the edges are connected to each other, and the maximum diameter of the cover rings is adapted to the diameter of the box port 2. A water bath pipe 3 is plugged inside the box port 2, and a sealing cover 7 is set at the pipe mouth of the water bath pipe 3, and a temperature sensor is installed on the sealing cover 7. The water bath pipe 3 establishes a basis for entering or leaving the water bath box 1 through a lifting component 4 installed inside the water bath box 1. The second-stage rod 422 in the lifting component 4 that controls the lifting of the water bath pipe 3 is set in the top box 11 to avoid the contact of the second-stage rod 422 with hot water. After the water bath pipe 3 reaches a predetermined temperature, the lifting component 4 pushes the water bath pipe 3 to the top of the top box 11, and releases the contact between the water bath pipe 3 and the bottom box 12, thereby enhancing the temperature control of the liquid in the water bath pipe 3.

[0026] In order to solve the problem in the prior art that the driving parts are all arranged in a water bath environment, and there is a risk of rust between the moving parts, water ingress or jamming, the water bath box 1 is separated into a top box 11 and a bottom box 12. The top box 11 is hollow inside and a box port 2 is opened on the top box 11. A temperature zone 13 and hot water are arranged inside the bottom box 12. A through hole 14 with the same diameter as the box port 2 is opened on the bottom box 12. The lifting component 4 includes a permeable pad 41 arranged in the bottom box 12. The diameter of the permeable pad 41 is larger than the diameter of the through hole 14. A plurality of permeable holes for overflow are opened on the permeable pad 41.

[0027] Lifting components 42 are installed at both ends of the permeable pad 41, and the lifting components include a first-order rod 421 and a second-order rod 422 connected to the first-order rod 421 and driving it to move up and down. The first-order rod 421 is arranged in the bottom box 12, and the second-order rod 422 is arranged in the top box 11. A slot 15 adapted to the diameter of the first-order rod 421 is opened on the top plate of the top box 11.

[0028] There are two first-order rods 421 arranged in a centrally symmetrical manner. Both first-order rods 421 are connected to the permeable pad 41 and extend vertically upward. The first-order rod 421 passes through the slot 15 and is connected to a connecting plate 423 in the top box 11. One end of the connecting plate 423 is sleeved on the second-order rod 422. The second-order rod 422 is threadedly connected to the connecting plate 423. The second-order rod 422 extends longitudinally upward and is coaxially connected to a drive motor 424 at its top end. The drive motor 424 is installed on the top plate of the top box 11. The water bath tube 3 includes a tube body and a stabilizing plug 5 installed at the lower end of the tube body for assisting in stabilizing the tube body. The stabilizing plug 5 is cylindrical and has an inner groove adapted to the diameter of the tube body at the center. By setting the cover plate 6 to be composed of a plurality of cover rings, different cover rings can be opened based on the diameter of the water bath tube 3 entering the water bath box 1. On the one hand, it can better adapt to the water bath tube 3 on the existing basis. On the other hand, it can increase the circumferential force on the water bath tube 3 while adapting to the diameter of the water bath tube 3, so that the water bath tube 3 can be stably extended into the water bath box 1, and a horizontal contact surface with the permeable top plate is generated with the help of the stabilizing plug 5 installed at the bottom of the water bath tube 3 to avoid skewing.

[0029] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
