However, there are some obvious defects and deficiencies in the existing medical electric thermostatic water bath technology, which limit its scope of use and flexibility.

[0003] First, although the existing medical electric constant temperature water bath is equipped with multiple temperature zones, the volume of each temperature zone cannot be changed. This fixed volume design brings many inconveniences in practical applications.

This means that experimenters cannot adjust the position of the racks according to experimental needs to optimize temperature distribution or meet specific heating requirements. This fixed design limits the flexibility and applicability of medical electric thermostatic water baths. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to make it easier to understand the structure of the present invention and the functional features and advantages that can be achieved, the preferred embodiments of the present invention are described in detail with reference to the drawings as follows:

[0020] Example:

[0021] like Figures 1 to 4 As shown, the utility model provides a medical electric constant temperature water tank, comprising a tank body 1, a tank cover 2, a heat insulation board 6 and a telescopic storage rack 7, wherein the heat insulation board 6 is slidably connected to the tank body 1, and a plurality of heat insulation boards 6 are installed in the tank body 1 to divide the tank body 1 into a plurality of independent temperature zones 8, each temperature zone 8 is respectively provided with an independent temperature control system 3 for constant temperature water control of the water in the tank body 1, so as to ensure the water temperature control accuracy of each temperature zone 8, and the temperature control system 3 automatically maintains a constant temperature according to the temperature set in each temperature zone 8, and a transverse limiting mechanism 4 is provided on the tank body 1, so that the heat insulation board 6 can be horizontally limited on the transverse limiting mechanism 4. The volume of each temperature zone 8 can be adjusted by moving, so as to adapt to different experimental volume requirements. A longitudinal limiting mechanism 5 is provided in the middle of the heat insulation board 6 and the two side walls of the tank body 1. The two ends of the telescopic shelf 7 are respectively installed on the two longitudinal limiting mechanisms 5. The telescopic shelf 7 is longitudinally moved on the longitudinal limiting mechanism 5 to adjust the depth of the telescopic shelf 7 in the tank body 1 to adapt to different depth placement requirements. The tank cover 2 is connected to the top of the tank body 1 by a hinged manner. The tank cover 2 is tightly combined with the tank body 1 to form a good seal, which effectively prevents the loss of heat and the entry of external impurities.

[0022] As another example, Figure 1The temperature control system 3 of the present application includes a heater 33, a cooler 32, a temperature sensor 31 and a control panel 34. The heater 33, the cooler 32 and the temperature sensor 31 are installed at the bottom of each temperature zone 8, and as the actuator of temperature regulation, they work according to the instructions of the temperature control system 3. When the water temperature is lower than the set value, the heater 33 will automatically start, and increase the water temperature by heating. When the water temperature reaches the set value, the heater 33 will automatically shut down. When the temperature setting value is lower than the room temperature, the cooler 32 will start, and reduce the water temperature by cooling. When the water temperature reaches the set value, the cooler 32 will automatically shut down. This intelligent temperature regulation method enables the water temperature to quickly and smoothly reach and maintain the set temperature, and can adapt to the experimental constant temperature requirements above or below the room temperature.

[0023] Furthermore, the heater 33, cooler 32 and temperature sensor 31 are electrically connected to the control panel respectively. The temperature sensor 31 is responsible for real-time monitoring of the water temperature in each temperature zone 8 and transmitting the real-time water temperature signal to the control panel 34. The control panel 34, as the hub of the entire temperature control system 3, is not only responsible for receiving and displaying the data of the temperature sensor 31, but also allows the user to set the required temperature value at any time through the interface. If the user sets a new temperature value, the control panel 34 will intelligently control the start and stop of the heater 33 or cooler 32 according to the real-time water temperature signal fed back by the temperature sensor 31 to ensure that the water temperature can quickly and accurately reach and maintain the new set value.

[0024] As another example, Figure 1 and Figure 4 The lateral limiting mechanism 4 includes a slide rail 41 and a latch 42 to achieve precise control of the lateral movement of the heat insulation board 6 in the tank body 1, thereby adjusting the volume of each temperature zone 8. The slide rail 41 is fixedly installed at the bottom of the tank body 1. It is made of wear-resistant and corrosion-resistant materials to ensure stability and reliability during long-term use. The length of the slide rail 41 matches the volume adjustment redundancy of each temperature zone 8, providing a smooth and stable track for the movement of the heat insulation board 6. A number of limiting holes 43 are opened at the top edge of the tank body 1 corresponding to the slide rail 41. The limiting holes 43 are arranged at a certain interval and are used to cooperate with the latch 42 to achieve precise locking of the moving position of the heat insulation board 6 to prevent the heat insulation board 6 from shaking or shifting during movement. The latch 42 is slidably arranged at the two corners of the upper end of the insulation board 6. The latch 42 can be retracted by manually pressing on the insulation board 6. When the position of the insulation board 6 needs to be fixed, the latch 42 only needs to be aligned with the corresponding limiting hole 43, and the pressing and sliding out of the latch 42 is released to achieve a firm lock. Through the cooperation of the slide rail 41 and the latch 42, the lateral limiting mechanism 4 realizes precise control of the lateral movement of the insulation board 6 in the trough body 1. The position of the insulation board 6 can be easily adjusted according to the experimental requirements, thereby changing the volume size of each temperature zone 8, which not only improves the flexibility and adaptability of the equipment, but also makes the experimental operation more convenient and efficient.

[0025] Furthermore, if Figure 4 The structure of the latch 42 includes a spring 422 and a T-shaped rod 421. The spring 422 of the latch 42 is sleeved on one end of the T-shaped rod 421. The spring 422 allows the T-shaped rod 421 to be inserted into or separated from the limiting hole 43 through its own elastic force. When the heat insulation board 6 is moved to adjust the volume of each temperature zone 8, the latch 42 is pressed to compress the spring 422, and the T-shaped rod 421 will be separated from the current limiting hole 43, pushing the heat insulation board 6 to move laterally in the tank body 1 until it reaches the desired position, aligning the latch 42 with the new limiting hole 43, and releasing the pressing. Under the elastic force of the spring 422, the T-shaped rod 421 will be inserted into the new limiting hole 43, thereby achieving a firm locking of the heat insulation board 6. Whether it is necessary to expand or reduce the volume of the temperature zone 8, it can be completed by simply pressing and moving the latch 42.

[0026] As another example, Figure 2 The longitudinal limiting mechanism 5 includes a slide bar 52, a guide rail 51, a fixing plate 53 and a knob 54. The guide rail 51 is fixedly installed in the middle of the heat insulation board 6, providing a stable and smooth moving track for the slide bar 52. One end of the slide bar 52 is fixedly connected to one end of the telescopic storage rack 7, and the slide bar 52 is installed inside the guide rail 51 to ensure that the slide bar 52 can move longitudinally along the guide rail 51. The fixing plate 53 is fixedly connected to the upper end of the guide rail 51, and a threaded hole is opened in the middle of the fixing plate 53. The knob 54 is threadedly connected to the fixing plate 53 through the threaded hole, so that the rotation of the knob 54 can be converted into a pressing force on the slide bar 52. When it is necessary to fix the telescopic shelf 7 at a certain depth of the slot body 1, the knob 54 is tightened, and its lower end gradually presses the slide bar 52, thereby limiting the longitudinal movement of the slide bar 52 on the guide rail 51, and the telescopic shelf 7 is firmly fixed at the current position. When it is necessary to adjust the depth of the telescopic shelf 7 in the slot body 1, the knob 54 is loosened, and the pressing force of the knob 54 on the slide bar 52 is reduced, so that the slide bar 52 can slide freely on the guide rail 51. The telescopic shelf 7 can be moved to a new depth position as needed, and the knob 54 is tightened again to fix it. The design of the longitudinal limit mechanism 5 is simple and practical, which not only ensures the stability of the telescopic shelf 7, but also provides a flexible adjustment function. The depth of the telescopic shelf 7 can be precisely controlled by simply operating the knob 54, thereby meeting different experimental requirements.

[0027] The working principle of the medical electric constant temperature water tank of this application:

[0028] First, according to the size of different constant temperature samples or containers required for the experiment, the volume of each temperature zone 8 of the medical electric constant temperature water bath is adjusted to meet the needs. In this process, the heat insulation board 6 is moved by pressing the latch 42 on the lateral limit mechanism 4. The movement of the heat insulation board 6 can change the volume of each temperature zone 8 to adapt to vessels of different sizes. After adjusting to the required size, release the latch 42, and the latch 42 will be fixed in the corresponding limit hole 43 to ensure that the heat insulation board 6 stays stably at the set position.

[0029] Then, the depth of the telescopic rack 7 in the tank body 1 is adjusted by the longitudinal limit mechanism 5. The telescopic rack 7 is slid up and down to the desired position by loosening the knob 54 and moving the slide bar 52. When the telescopic rack 7 reaches the appropriate depth, the knob 54 is tightened to fix the depth of the test rack, the experimental samples or containers are placed, an appropriate amount of water is added to each temperature zone 8, and the tank cover 2 is closed.

[0030] Finally, according to the constant temperature requirements of each experimental sample or container, the constant temperature of each temperature zone 8 is set on the control panel 34. After the setting is completed, the switch is closed and the medical electric constant temperature water bath starts to work. The temperature sensor 31 of each temperature zone 8 detects the water temperature in real time and transmits the real-time water temperature signal to the control panel 34. The control panel 34 automatically controls the start and stop of the heater 33 or the cooler 32 according to the comparison between the set temperature and the real-time water temperature, thereby ensuring that the water temperature of each temperature zone 8 is always maintained within the set constant temperature range.

Any technician familiar with the field can make many possible changes and modifications to the technical solution of the present invention by using the above technical content without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes.
