DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0031] Embodiment: refer to Figures 1-4 The constant temperature water bath box with ultraviolet sterilization function shown in the figure comprises a water bath box body 1, a water tank 11 is arranged in the middle of the water bath box body 1, a box cover 12 is hingedly connected to the upper portion of the water bath box body 1 and closes the upper opening of the water tank 11, an ultraviolet lamp 2 is fixed to the inner side of the box cover 12, and a control cabinet 13 is arranged on one side of the water tank 11;

[0032] A passage 14 is formed in the lower portion of the water tank 11 and away from the control cabinet 13, a water level flat cavity 15 is formed at the tail end of the passage 14 away from the water tank 11, a movable cavity 16 is formed in the upper portion of the water level flat cavity 15, and the water level flat cavity 15 and the movable cavity 16 are communicated through a water inlet hole 17;

[0033] A water storage tank 3 is fixed to the upper portion of the side of the water bath box body 1 away from the control cabinet 13, a water inlet 31 is fixed to the upper end of the water storage tank 3, and a drain hole 33 is formed in the bottom of the water storage tank 3 and communicated with the movable cavity 16;

[0034] A floating sealing structure 4 is installed in the movable cavity 16, and the lower end of the floating sealing structure 4 is slidably penetrated through the bottom of the movable cavity 16 and extended into the water level flat cavity 15;

[0035] The lower end of the floating sealing structure 4 rises as the water level in the water level cavity 15 increases. When the water level in the water level cavity 15 rises to the same level as the highest water level in the water tank 11, the upper end of the floating sealing structure 4 closes the drain hole 33. When the water level in the water level cavity 15 decreases, the upper end of the floating sealing structure 4 decreases and opens the drain hole 33, so that the water storage tank 3 is connected to the water level cavity 15 through the drain hole 33, the movable cavity 16 and the inlet hole 17.

[0036] Based on the above structure, by setting up a water storage tank 3 and pre-filling it with water, water can be automatically added to the water tank 11 through the water level cavity 15 in cooperation with the water storage tank 3 and the floating sealing structure 4. Specifically, when the water level in the water level cavity 15 drops, the upper end of the floating sealing structure 4 lowers and opens the drain hole 33, allowing the water storage tank 3 to connect with the water level cavity 15 through the drain hole 33, the movable cavity 16, and the inlet hole 17. This allows water in the water storage tank 3 to flow into the water level cavity 15 and further into the water tank 11 through the channel 14, achieving the purpose of automatic water addition. This can be achieved even after long-term use. The system features real-time automatic water filling, eliminating the need for staff to monitor alarms or perform frequent water filling operations. It also eliminates the need to shut down the equipment for water filling, ensuring continuous and normal operation for extended periods and significantly reducing staff workload. Furthermore, when the water level in the level chamber 15 rises to the same level as the highest water level in the water tank 11, the upper end of the floating sealing structure 4 closes the drain hole 33, stopping the water filling operation into the water tank 11. This system automatically adds and stops water based on the water level, meeting actual usage needs and providing better performance.

[0037] In addition, a transparent observation window 32 can be set at the front of the water storage tank 3. Staff only need to observe the water level in the water storage tank 3 at regular intervals (after a long period of time) and add water to the water storage tank 3. Compared with the existing water filling method, the frequency of water filling can be greatly reduced, and the labor intensity of staff can be reduced.

[0038] Furthermore, the floating plugging structure 4 includes:

[0039] Hollow float 41 is located inside the water level cavity 15 and floats on the water surface inside the water level cavity 15.

[0040] Support column 42, the lower end of support column 42 is fixed to the upper end of hollow float 41, and the upper end of support column 42 slides through the top of the water level cavity 15 and extends into the movable cavity 16.

[0041] The sealing plate 43 is fixed to the upper end of the support column 42. When the water level in the water level cavity 15 is the same as the highest water level in the water tank 11, the upper end of the sealing plate 43 abuts against the top of the movable cavity 16 and closes the drain hole 33.

[0042] The water level in the water level cavity 15 is the same as the water level in the water tank 11. When the water level in the water level cavity 15 is the same as the highest water level in the water tank 11 (referring to the preset applicable water level), the upper end of the sealing plate 43 abuts against the top of the movable cavity 16 and closes the drain hole 33. At this time, there is no water addition action. When the water level in the water level cavity 15 drops, the hollow float 41 drops accordingly, so that the support column 42 and the sealing plate 43 drop synchronously. After the sealing plate 43 separates from the drain hole 33, the water storage tank 3 is connected to the water level cavity 15 through the drain hole 33, the movable cavity 16 and the water inlet hole 17, thereby achieving the purpose of automatic water addition.

[0043] Furthermore, a counterweight 44 is fixed to the lower end of the hollow float 41. The counterweight 44 is a cone with its tip pointing downwards. By setting the counterweight 44, the center of gravity of the hollow float 41 can be lowered, thereby ensuring that the hollow float 41 can remain stable when the water level rises and falls.

[0044] Furthermore, there is a gap between the periphery of the hollow float 41 and the inner wall of the water level cavity 15. Multiple water inlets 17 are provided and evenly distributed along the periphery of the support column 42. The upper end of the hollow float 41 coincides with the position of multiple water inlets 17, so that the top of the hollow float 41 closes multiple water inlets 17 after rising. This prevents the water level in the water tank 11 from continuously rising due to the connection between the water level cavity 15 and the movable cavity 16, which would cause the water level in the water tank 11 to exceed the preset maximum water level, affecting use, or even causing the water in the water tank 11 to overflow and damage the water bath tank body 1.

[0045] Furthermore, a guide rod 7 is fixed at the bottom of the water storage tank 3, and multiple guide rods 7 are provided and distributed around the circumference of the drain hole 33;

[0046] The water tank 3 is also equipped with a sealing plate 5. The sealing plate 5 has through holes 51 for multiple guide rods 7 to slide through. Magnetic blocks 6 are fixed at the lower end of the sealing plate 5 and the top of the sealing plate 43. The two magnetic blocks 6 are magnetically attracted to each other.

[0047] Among them, the magnetic attraction force of the two magnetic blocks 6 is less than the weight of the counterweight 44, and the weight of the hollow float 41, the support column 42, the sealing plate 43 and the counterweight 44 is less than the buoyancy of the water in the water level cavity 15 on the hollow float 41.

[0048] A top plate 71 is fixed to the upper end of the guide rod 7. A return spring 8 is movably sleeved on the guide rod 7. The upper and lower ends of the return spring 8 are fixed to the bottom of the top plate 71 and the upper surface of the sealing plate 5, respectively. The return spring 8 applies an upward pulling force to the sealing plate 5, and the pulling force applied by the return spring 8 to the sealing plate 5 is less than the magnetic attraction force between the two magnetic blocks 6.

[0049] When the top of the sealing plate 43 abuts against the top of the movable cavity 16, the two magnetic blocks 6 attract each other magnetically, causing the sealing plate 5 to descend against the elastic force of the return spring 8. This closes the upper end of the drain hole 33, thus achieving a double sealing effect between the sealing plate 5 and the sealing plate 43. This further ensures that after the water level in the water level cavity 15 reaches its maximum, the water tank 3 stops adding water to the water level cavity 15, thereby further preventing the water level from rising continuously. When the sealing plate 43 descends, the two magnetic blocks 6 move away from each other and lose their attraction. At this time, the sealing plate 5 rises under the elastic force of the return spring 8, thereby opening the drain hole 33 for automatic water filling.

[0050] The working principle of this utility model is as follows: During daily use, the water storage tank 3 is pre-filled with water. With the cooperation of the water storage tank 3 and the floating sealing structure 4, water is automatically added to the water tank 11 through the water level cavity 15. Specifically, when the water level in the water level cavity 15 drops, the hollow float 41 drops accordingly, causing the support column 42 and the sealing plate 43 to drop synchronously. After the sealing plate 43 separates from the drain hole 33, the water storage tank 3 connects to the water level cavity 15 through the drain hole 33, the movable cavity 16, and the inlet hole 17, allowing water in the water storage tank 3 to flow into the water level cavity 15 and further into the water tank 11 through the channel 14, achieving the purpose of automatic water addition. Afterwards, when the water level in the water level cavity 15 rises to... When the water level in the water tank 11 reaches the highest level, the upper end of the sealing plate 43 abuts against the top of the movable cavity 16 and closes the drain hole 33, thereby stopping the water filling operation into the water tank 11. At the same time, the two magnetic blocks 6 attract each other magnetically, causing the sealing plate 5 to overcome the elastic force of the return spring 8 and descend, thereby closing the upper end of the drain hole 33. This achieves a double sealing effect of the sealing plate 5 and the sealing plate 43, further ensuring that after the water level in the water level cavity 15 reaches the highest level, the water storage tank 3 stops adding water to the water level cavity 15, thereby further avoiding the situation where the water level continues to rise, causing the water level in the water tank 11 to exceed the preset highest water level, affecting use, or even causing the water in the water tank 11 to overflow and damage the water bath tank body 1.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
