Technical Field
[0001] This utility model relates to the technical field of water bath heating, and more specifically, it relates to a constant temperature water bath with automatic water replenishment. Background Technology
[0002] Water baths are mainly used in laboratories for distillation, drying, concentration, and warm soaking of chemicals or biological products. They can also be used for constant temperature heating and other temperature tests. They are an essential tool for biology, genetics, virology, aquaculture, environmental protection, medicine, health, laboratories, analytical laboratories, education and scientific research.
[0003] During the long-term constant temperature water bath heating process, the water in the water bath will gradually evaporate, causing the liquid level in the water bath to drop. In order to ensure the normal operation of the water bath heating, the operator needs to frequently monitor the remaining water in the water bath so as to add water in time to prevent the water bath from drying out. This means that long-term constant temperature water bath heating requires a lot of effort from the test personnel. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide an automatic water-replenishing constant temperature water bath. Through the water tank, it can automatically replenish water to the constant temperature bath when the bath is short of water. During the water replenishment process, the water passes through the receiving cavity and is heated to the same temperature as the water in the constant temperature bath by the heating component inside the receiving cavity. This reduces the effort required by the experimenters and does not affect the water temperature inside the constant temperature bath due to water replenishment.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic water replenishment constant temperature water bath, comprising a constant temperature bath body, wherein a heating element is provided in the constant temperature bath body to maintain a constant temperature of the water inside the constant temperature bath body;

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.
[0029] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.
[0030] Example: A constant temperature water bath with automatic water replenishment, see attached document. Figure 1 -Appendix Figure 6 The system includes a constant temperature pot body 1, a water tank 2, a receiving cavity 31, a heating element, a water pump 6, and a water level sensor 4. The constant temperature pot body 1 is equipped with a heating element to maintain a constant temperature of the water inside the pot body 1. The water tank 2 is located on one side of the constant temperature pot body 1 and stores room temperature water. The receiving cavity 31 is located on one side of the constant temperature pot body 1 and is connected to the constant temperature pot body 1 near the top. The heating element is located in the receiving cavity 31 to heat the room temperature water passing through the receiving cavity 31 to the same temperature as the water inside the constant temperature pot body 1. The water pump 6 is used to transport water from the water tank 2 to the receiving cavity 31 near the bottom. The water level sensor 4 is located in the constant temperature pot body 1 and is connected to the water pump 6.
[0031] Specifically, the water level sensor 4 is used to detect the water level inside the constant temperature pot 1. During the test, a main control unit is set up, which is connected to the water level sensor 4, the water pump 6, and the heating component. The main control unit can be set as a PLC, and the maximum and minimum water levels inside the constant temperature pot 1 are preset in the main control unit. During the constant temperature test, when the water level sensor 4 detects that the water level inside the constant temperature pot 1 has reached the minimum water level, the water level sensor 4 transmits the information to the main control unit. The main control unit controls the water pump 6 to turn on, and the water pump 6 delivers water to the receiving cavity 31. At the same time, the main control unit controls the heating component to start heating. The water enters the constant temperature pot 1 through the receiving cavity 31 and, after being heated in the receiving cavity 31, the water temperature is the same as the water temperature inside the constant temperature pot 1. Then the water flows from the receiving cavity 31 back into the constant temperature pot 1. When the water level sensor 4 detects that the water level inside the constant temperature pot 1 has reached the maximum water level, it transmits the information to the main control unit, and the main control unit controls the water pump 6 and the heating component to stop working.
[0032] Specifically, a transition shell 3 is fixedly connected to the side of the constant temperature pot body 1 near the water tank 2, and the inner cavity of the transition shell is set as a receiving cavity 31.
[0033] Specifically, a plurality of partition plates 32 are provided inside the receiving cavity 31. The partition plates 32 are arranged vertically, and both sides of the partition plates 32 are fixedly connected to the inner wall of the receiving cavity 31. The two ends of the partition plates 32 are the first end and the second end, respectively. The partition plates 32 are divided into a first partition plate 32 and a second partition plate 32. The first end of the first partition plate 32 is fixedly connected to the inner wall of the receiving cavity 31, and a gap is left between the second end and the inner wall of the receiving cavity 31. The second end of the second partition plate 32 is fixedly connected to the inner wall of the receiving cavity 31, and a gap is left between the first end and the inner wall of the receiving cavity 31. The first partition plates 32 and the second partition plates 32 are arranged alternately in the vertical direction.
[0034] By setting the first partition plate 32 and the second partition plate 32, a serpentine channel for water flow can be formed in the receiving cavity 31, which increases the heating time of water in the receiving cavity 31 and ensures that the room temperature water entering the receiving cavity 31 can be heated for a sufficient time to be consistent with the temperature of the water in the constant temperature pot 1.
[0035] Specifically, the heating component includes an electric heating plate 7, and multiple electric heating plates 7 are provided, with one electric heating plate 7 fixedly connected to the top of each partition plate 32.
[0036] Specifically, a water inlet 11 is provided near the top of the side of the transition shell 3 that is connected to the constant temperature pot body 1, and a temperature sensor 5 is provided inside the water inlet 11; the temperature sensor 5 is connected to multiple electric heating plates 7.
[0037] Temperature sensor 5 is connected to the main control module. Temperature sensor 5 is used to detect the water temperature flowing through inlet 11. When the water temperature flowing through inlet 11 is higher than the water temperature inside the constant temperature pot 1, the main control module controls multiple electric heating plates 7 to reduce power. When the water temperature flowing through inlet 11 is lower than the water temperature inside the constant temperature pot 1, the main control module controls multiple electric heating plates 7 to increase power.
[0038] Specifically, the water pump 6 has an inlet pipe 61 connected to its inlet end, which is connected to two first connecting pipes 611 via a tee. The two first connecting pipes 611 are respectively connected to the transition housing 3 and the water tank 2 near the bottom. The water pump 6 has an outlet pipe 62 connected to its outlet end, which is connected to two second connecting pipes 621 via a tee. The two second connecting pipes 621 are respectively connected to the transition housing 3 and the water tank 2 near the bottom. Solenoid valves are installed on both the first connecting pipes 611 and the second connecting pipes 621.
[0039] When water pump 6 needs to transfer water from water tank 2 to receiving cavity 31, the solenoid valves on the first connecting pipe 611 connected to water tank 2 and the second connecting pipe 621 connected to transition shell 3 open, and the solenoid valves on the first connecting pipe 611 connected to transition shell 3 and the second connecting pipe 621 connected to water tank 2 close, allowing water to enter receiving cavity 31 from water tank 2. When the water in constant temperature pot 1 is completely filled, water pump 6 stops working. At this time, water still remains in receiving cavity 31 to prevent water from being added to constant temperature pot 1 again. The water remaining in the containment cavity 31 enters the constant temperature pot 1 directly without being heated. The water pump 6 pumps the water in the containment cavity 31 back to the water tank 2. At this time, the solenoid valves on the first connecting pipe 611 connected to the transition shell 3 and the second connecting pipe 621 connected to the water tank 2 are opened, and the solenoid valves on the first connecting pipe 611 connected to the water tank 2 and the second connecting pipe 621 connected to the transition shell 3 are closed. The water is transported from the containment cavity 31 to the water tank 2 by the water pump 6, so that in the initial state of the next water replenishment to the constant temperature pot 1, there is no residual water in the containment cavity 31.
[0040] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
