Description

Technical Field

[0001] This utility model relates to the field of water bath technology, specifically to a constant temperature water bath. Background Technology

[0002] Thermostatic water baths are mainly used in laboratories for distillation, drying, concentration, and warm soaking of chemical reagents or biological products. They can also be used for constant temperature heating and other temperature tests. They are essential equipment in fields such as biology, chemistry, analytical laboratories, and cosmetics research, and are used to bathe beakers, flasks, and other laboratory vessels in water.

[0003] Currently, existing constant temperature water baths require manual addition of water while visually monitoring the water level to ensure it remains within a certain range. This process is prone to errors, resulting in water levels that are too low or too high. If the water level is too low, it affects experimental accuracy; if it is too high, water may overflow during heating. Furthermore, the water in the constant temperature water bath needs to be drained after the experiment, leading to water waste. Utility Model Content

[0004] The purpose of this invention is to design a constant temperature water bath that can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A constant temperature water bath includes a housing and a water storage tank. A water level sensor is installed on the inner wall of the housing. A drain pipe is connected to the bottom of the housing, and the other end of the drain pipe is connected to the water storage tank via a drain pump. A water inlet pipe is connected to the side wall of the housing, and the other end of the water inlet pipe is connected to the water storage tank via a water inlet pump. The bottom of the housing is a slope, and the water inlet of the drain pipe is located at the lowest point of the slope. A controller is installed on the outer wall of the housing. The water level sensor, the drain pump, and the water inlet pump are all electrically connected to the controller.

[0007] Furthermore, the interior of the box is provided with a perforated partition and a heating rod from top to bottom. The heating rod is fixed to the inner wall of the box, and four inner support blocks corresponding to the four corners of the perforated partition are fixedly connected to the inner wall of the box.

[0008] Furthermore, the inner wall of the housing is provided with a groove, and the water level sensor is installed inside the groove.

[0009] Furthermore, the top of the box is provided with a box cover, the top of the box cover is provided with several water bath holes, and a pot lid is provided at the water bath holes.

[0010] Furthermore, the water bath has two holes.

[0011] Furthermore, a filter is installed on the drain pipe.

[0012] Furthermore, the top of the water storage tank is provided with a tank cover.

[0013] Furthermore, the bottom of the water storage tank is connected to a drain pipe.

[0014] Furthermore, the controller has a display screen and operation buttons on its surface.

[0015] The beneficial effects of this utility model are as follows:

[0016] The water pump is started by controlling the controller. The water pump will discharge water from the storage tank into the tank through the water inlet pipe. The water level sensor monitors the real-time water level in the tank and feeds the signal back to the controller. When the water level reaches the controller's set value, the controller will stop the water pump. This precisely controls the water level in the water bath to be within a certain range, preventing the water level in the water bath from being too low or too high.

[0017] After the experiment, the drain pump is started by controlling the controller. The drain pump will discharge the water in the tank into the storage tank through the drain pipe, thus recycling the water and saving water resources. Attached Figure Description

[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] like Figure 1-4 As shown, a constant temperature water bath includes a housing 1 and a water storage tank 2. Inside the housing 1, from top to bottom, are perforated partitions 10 and heating rods 11. The heating rods 11 are used to heat the water, and the perforated partitions 10 are used to support experimental equipment. The heating rods 11 are fixed to the inner wall of the housing 1. Four inner support blocks 12, corresponding one-to-one with the four corners of the perforated partitions 10, are fixedly connected to the inner wall of the housing 1 to facilitate the disassembly of the perforated partitions 10 for cleaning the interior of the housing 1. A groove 13 is provided on the inner wall of the housing 1, and a water level sensor 3 is installed inside the groove 13. This prevents the perforated partitions 10 from colliding with the water level sensor 3 during disassembly, thus preventing damage to the water level sensor. A drain pipe 4 is connected to the bottom of the housing 1, and the other end of the drain pipe 4 is connected to the water storage tank 2 via a drain pump 5. Starting the drain pump 5... 5 will drain the water in tank 1 into storage tank 2 through drain pipe 4, recycling the water and saving water resources; the side wall of tank 1 is connected to water inlet pipe 6, and the other end of water inlet pipe 6 is connected to storage tank 2 through water inlet pump 7. When water inlet pump 7 is started, water in storage tank 2 will be drained into tank 1 through water inlet pipe 6; the bottom of the inside of tank 1 is a slope 8, and the water inlet of drain pipe 4 is located at the lowest point of slope 8, allowing the water in tank 1 to flow to the lowest point of slope 8 and be discharged with drain pipe 4, reducing the amount of water remaining in tank 1; a controller 9 can be installed on the outer wall of tank 1. Water level sensor 3, drain pump 5, water inlet pump 7 and heating rod 11 are all electrically connected to controller 9. The controller 9 controls the water level sensor 3, drain pump 5, water inlet pump 7 and heating rod 11 to start, and to set the water level and water temperature;

[0027] The top of the chamber 1 is equipped with a lid 14, and the top of the lid 14 has two water bath holes 15 for placing experimental equipment. A pot lid 16 is installed at the water bath holes 15, and a filter 17 is installed on the drain pipe 4. During the experiment, foreign objects may inevitably fall into the chamber 1, and the filter 17 can filter the water discharged from the chamber 1. The top of the water storage tank 2 is equipped with a tank lid 18, which serves to seal the water and prevent it from being contaminated by foreign objects during storage. The bottom of the water storage tank 2 is connected to an empty pipe 19, which is used to empty the water storage tank 2 after the water in the water storage tank 2 has been recycled multiple times, so as to clean the water storage tank 2. The surface of the controller 9 is equipped with a display screen 20 and operation buttons 21. The display screen 20 is used to display data such as water temperature and water level, and the controller 9 is operated by the operation buttons 21.

[0028] Working principle:

[0029] like Figure 1-4 As shown, when using the constant temperature water bath, the water level and temperature are first set by the controller 9. Then, the controller 9 controls the water pump 7 and heating rod 11 to start. The water pump 7 will discharge the water in the water storage tank 2 into the chamber 1 through the water inlet pipe 6. The water level sensor 3 monitors the real-time water level in the chamber 1 and feeds the signal back to the controller 9. When the water level reaches the set value of the controller 9, the controller will control the water pump to stop, accurately controlling the water level in the water bath within a certain range to prevent the water level in the water bath from being too low or too high. After stopping the water supply, the experimental apparatus can be used for experiments.

[0030] After the experiment, the controller 9 stops the heating rod 11 and starts the drain pump 5. The drain pump 5 will then drain the water in the tank 1 into the water storage tank 2 through the drain pipe 4 to recycle the water and save water resources.
