[0024] like Figures 1 to 4 As shown, in one embodiment, a multi-station constant temperature water tank includes a water bath body 100, a water tank flap 200, a hinge 300 and a heating device. The water bath body 100 is a rectangular parallelepiped box with a heating tank 110 inside and an open top; the water tank flap 200 includes a flap fixing frame 210 and a tempered glass cover 220 arranged in the flap fixing frame; one side of the hinge 300 is fixedly connected to the upper end of the outer wall of the water bath body 100, and the other side is fixedly connected to the water tank flap 200, so that the water bath body 100 and the water tank flap 200 are rotatably connected.

[0025] In this embodiment, the water tank flip cover 200 is a rectangular plate-shaped structure, the size of which matches the size of the water bath box 100, so that the water tank flip cover 200 can be tightly covered with the water bath box 100; the water tank flip cover 200 includes a flip cover fixing frame 210 with a rectangular frame structure and a tempered glass cover 220 arranged in the flip cover fixing frame 210, and the inner side walls of the flip cover fixing frame 210 are provided with grooves for mounting the tempered glass cover 220, and the height of the grooves is the same as the thickness of the tempered glass cover 220, so that the tempered glass cover 220 is snapped into the grooves on the flip cover fixing frame 210 for fixation.

[0026] Furthermore, in order to increase the sealing performance of the water tank flap 200, a sealing strip 230 is provided under the flap fixing frame 210. There are four sealing strips 230, which are respectively arranged under the four side walls of the flap fixing frame 210, and the four sealing strips 230 are connected to form a mouth-shaped structure. The shape of the lower surface of the sealing strip 230 matches the shape of the upper end of the side wall of the water bath box body 100 covering the position on the water bath box body 100, so that the two can fit tightly. The sealing strip 230 is made of rubber material, which has good high temperature resistance, hot water resistance, superheated steam resistance and corrosion resistance, and can further improve the overall sealing performance of the interior of the constant temperature water tank and reduce the heat emitted from the interior of the constant temperature water tank to the outside during heating.

[0027] In order to reduce the damage to the water tank flap 200 and the water bath body 100 caused by excessive force when closing the water tank flap 200, the hinge 300 adopts a hydraulic hinge. The structure of the hydraulic hinge is simple and easy to install. Its installation process is the same as that of an ordinary hinge, and no additional steps are required. A torsion spring is provided inside the hinge 300. When it is opened, the reaction force generated by the twisting and deformation of the torsion spring can automatically close the water tank flap 200 after opening. A small oil cylinder is provided in the central axis of the hydraulic hinge. The piston slides in the oil cylinder to produce a blocking effect, which can slow down the closing speed of the water tank flap 200 and avoid the noise and impact caused by rapid closing. The hydraulic hinge also has a speed adjustment function and a door stop function. It can adjust the closing speed of the water tank flap 200 as needed and temporarily stop the water tank flap 200 after opening to a certain angle, which is convenient for daily use. It is worth noting that the hydraulic hinge is a prior art and corresponding hydraulic hinges can be found on the existing market. It will not be elaborated on in detail here.

[0028] Furthermore, in order to better utilize the internal space of the water bath body 100, the side walls of the water bath body 100 are set to a double-layer structure, wherein the interior of the four side walls is a hollow interlayer, which can be used for the installation of other devices and isolate the temperature transfer of the heating tank 110, thereby preventing the water bath body 100 from scalding the operator and improving the safety of the constant temperature water tank; wherein, a display hole 120 is opened on an outer side wall of the water bath body 100, and the display hole 120 is a rectangular structure, connected to the outer layer of the side wall. The display hole 120 is used for the installation of the display panel and touch buttons in the controller, so that it is convenient to view the temperature inside the heating tank 110 displayed on the display panel through the display hole 120 and adjust the required temperature and stirring speed.

[0029] In order to control the heating temperature in the heating tank 110, a control system is provided in the water bath body 100, which includes a controller and a sensor. The controller is installed in the interlayer of the side wall of the water bath body 100 with a display hole 120 and is connected to an external power supply. A display panel and touch buttons are provided on the front side of the controller. The display panel and touch buttons are located in the display hole 120. The display panel can display the real-time temperature, target temperature and stirring intensity in the heating tank 110. The touch buttons include a temperature adjustment button and a stirring intensity adjustment button. The user can control the switch of the heating device and adjust the set temperature through the temperature adjustment button; and control the switch and stirring intensity of different stirring devices through the stirring intensity adjustment button; the sensor includes a temperature sensor, which is arranged inside the water bath body 100 and electrically connected to the controller for detecting the water temperature inside the heating tank 110, realizing real-time monitoring of the water temperature, and transmitting temperature data to the controller, and displaying the real-time temperature on the display panel, so as to facilitate timely adjustment of the power of the heating device.

[0030] Exemplarily, the heating device is a nano-ceramic heating plate, which is an electric heating plate with a nano-heating coating sprayed on a microcrystalline ceramic and then an electrode installed; the heating device is arranged at the bottom of the heating tank 110 and is electrically connected to the controller. The output power of the heating device is controlled by the controller so that the temperature in the water bath box 100 remains stable, which facilitates the experiment; it should be noted that the structure of the nano-ceramic heating plate is known to those skilled in the art and is achievable. In this embodiment, it will not be elaborated on.

[0031] Furthermore, in order to stir the reagent in the heating container during heating, a plurality of magnetic stirring devices are further provided in the water bath body 100. The plurality of magnetic stirring devices are arranged in an array at the bottom of the water bath body 100, and the adjacent two magnetic stirring devices are spaced apart so that the magnetic stirring devices do not affect each other during operation. In this embodiment, the number of the magnetic stirring devices is six, and the six magnetic stirring devices are arranged in an array, and the distance between two adjacent magnetic stirring devices is the same, and they do not contact the side walls of the water bath body 100. The plurality of magnetic stirring devices are all electrically connected to the controller, and the plurality of magnetic stirring devices can perform stirring work simultaneously, or each magnetic stirring device can work independently, that is, not only can a plurality of magnetic stirring devices perform stirring simultaneously in the water bath body 100, but the stirring speeds can be the same or different; a magnetic stirring device can also be used alone to stir a heating container, which can be used flexibly according to different usage scenarios.

[0032] Furthermore, in order to enable the heating container to be stably placed inside the heating tank 110 when using the water bath box body 100, a support plate 400 is provided in the heating tank 110. The shape and size of the support plate 400 are the same as the horizontal cross-section inside the heating tank 110. A plurality of long strip-shaped filtering through holes 410 connecting the upper and lower surfaces of the support plate 400 are provided on the surface of the support plate 400. The filtering through holes 410 are arranged on the surface of the support plate 400 in a regular distribution; fixed parts are provided at both ends of the support plate 400, and the fixed parts match the supporting grooves provided on the two opposite side walls in the heating tank 110. The fixed parts of the support plate 400 are inserted into the supporting grooves in the heating tank 110 to realize the detachable connection between the support plate 400 and the water bath box body 100.

[0033] Furthermore, in order to prevent the container from tipping over when there is too little reagent in the heating container, a sealed inner cover 500 is provided on the upper end surface of the heating tank 110. The size of the sealed inner cover 500 is the same as the size of the upper end surface of the heating tank 110. The sealed inner cover 500 is placed on the upper surface of the water bath box 100 to cover the heating tank 110, thereby realizing a detachable connection between the sealed inner cover 500 and the water bath box 100; both ends of the upper end surface of the sealed inner cover 500 are provided with lifting rings for lifting the sealed inner cover 500 and separating it from the water bath box 100; the sealed inner cover 500 is also provided with a plurality of placement holes 510, the positions of the plurality of placement holes 510 correspond one-to-one to the positions of the magnetic stirring devices, and the placement holes 510 are used to place the heating container into the heating tank 110 for heating. In this embodiment, the shape of the placement holes 510 is cylindrical, and the number is the same as the number of the magnetic stirring devices. In order to prevent the heating container from tipping over, a ring cover 520 is provided on the multiple placement holes 510. The ring cover 520 is composed of multiple circular rings 521 of different calibers and an intermediate circular plate 522. Multiple circular rings 521 and the intermediate circular plate 522 are connected in sequence to form a disc-shaped ring cover 520, and an anti-scalding button 523 is provided above the intermediate circular plate 522. When using a constant temperature water tank, the appropriate number of circular rings 521 can be uncovered according to the size of different heating containers, so that containers of different sizes can find holes of appropriate sizes for placing heating containers, so that the containers can be caught when the heating containers tip over, preventing the reagents in the containers from pouring into the water bath box 100, thereby affecting the service life of the constant temperature water tank.

[0034] It should be noted that the water bath body 100, support plate 400, and sealed inner cover 500 in this embodiment are all made of stainless steel. Stainless steel has good thermal conductivity and corrosion resistance, and can transfer the heat generated by the heating device to the water, thereby increasing the heating rate. It can also reduce rust and corrosion in the constant temperature water tank and increase the service life. The sealing strip 230 and the ring cover 520 are both made of rubber material. Since rubber material has good sealing and high temperature resistance, it can improve the sealing of the constant temperature water tank and prevent the experimenter from being burned when opening the ring cover 520. In addition, the rubber material is also elastic, which can prevent the heating container from colliding with the ring cover 520 and breaking when it overturns, thereby improving the safety of the experiment.

[0035] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention.
