Description

Technical Field

[0001] The utility model relates to the field of constant temperature water tanks, in particular to an electric constant temperature water tank. Background Art

[0002] The electric thermostatic water bath is a device whose core function is to maintain the stability of the liquid temperature in the water bath. It consists of key components such as the water bath, heater and temperature controller. The working principle of the electric thermostatic water bath is to heat the water in the water bath to a preset temperature through the heater, and then the temperature controller is responsible for monitoring and regulating the water temperature to ensure that it is constant at the set value.

[0003] However, electric thermostatic water baths may face efficiency issues when placing test tubes. This may stem from the inconvenience of the water bath design or the way it is used. For example, if the opening size of the water bath is small, or the size of the test tube does not match the water bath, this may cause difficulties in placing the test tube, thereby increasing the operation time and effort. In addition, if the water bath heats up slowly, it takes a long time to reach the required test temperature, which will further reduce the test efficiency. Utility Model Content

[0004] The main purpose of the utility model is to provide an electric constant temperature water tank, which can effectively solve the problems raised in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] An electric thermostatic water tank comprises an electric thermostatic box, a circulating water pump, a circulating pipe, a valve and a heater, wherein the circulating water pump is connected to the electric thermostatic box through the circulating pipe, the circulating pipe is provided with a valve, the heater is provided on the electric thermostatic box and heats the water flow in the electric thermostatic box; a thermostatic water tank is provided on the upper end of the electric thermostatic box, a heating water tank is provided on the upper end of the thermostatic water tank, a straight bar is provided in the heating water tank, a plurality of round holes are provided on the upper end of the straight bar, and a test tube with a heating thermostat is inserted into each of the round holes;

A plurality of limit blocks are provided on both sides of the lower end of the straight strip. A limit groove is provided between each of the limit blocks. The upper end of the fastening strip is clamped in the limit groove. The fastening strip adjusts its position in the limit groove and adjusts the curvature of the elastic strip, thereby adjusting the extrusion force of the elastic strip to make it close to the groove wall of the heating water tank.

[0009] As a further preferred embodiment of the present invention, the elastic strip and the detour portion are designed as one piece, and the cross-sections of the elastic strip and the detour portion are designed in an "Ω" shape, and the connection between the elastic strip and the straight strip is designed in an arc shape;

[0010] As a further preferred embodiment of the present invention, a high temperature resistant rubber gasket is provided on the surface of the elastic strip, and the elastic strip is closely attached to the wall of the heating water tank through the high temperature resistant rubber gasket, and the lower end of the elastic strip contacts the inner bottom of the heating water tank;

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the utility model, the design uses a straight bar to ensure that the test tube is stably placed in the heating water tank to avoid movement or tilting during the heating process. The straight bar runs through the heating water tank, and the test tube is inserted into the round hole of the straight bar, which can ensure that the test tube is heated evenly, thereby improving the heating efficiency. In addition, the elastic bar can adjust the squeezing force on the test tube through its curvature, ensuring that the test tube fits tightly on the wall of the heating water tank to ensure uniform heating.

[0015] To further enhance stability, the fastening strip is designed to fix the position of the straight strip and the test tube to prevent them from loosening or falling off during heating.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1 - Figure 4 As shown, an electric thermostatic water tank is mainly composed of key components such as an electric thermostatic box 1, a circulating water pump 2, a circulating pipe 3, a valve 4, a heater 5 and a thermostatic water tank 6. The circulating water pump 2 is connected to the electric thermostatic box 1 through the circulating pipe 3 to form a closed circulation loop. The circulating pipe 3 is equipped with a valve 4 to control the switch and flow rate of the water flow. The heater 5 is installed on the electric thermostatic box 1, and its function is to provide continuous heating for the water flow in the electric thermostatic box 1 to maintain a constant water temperature; the upper end of the electric thermostatic box 1 is equipped with a thermostatic water tank 6, and the upper end of the thermostatic water tank 6 is provided with a heating water tank 7. A straight bar 8 is set up inside the heating water tank 7. The upper end of the straight bar 8 is designed with multiple circular holes, and a test tube 14 with a heating and thermostatic function is inserted into each circular hole; in order to ensure the stability and uniform heating of the test tube 14 in the heating water tank 7, elastic strips 9 are provided at both ends of the straight bar 8. A detour 10 is designed in the middle of the elastic strip 9 to increase its elasticity. The lower end of the elastic strip 9 is connected to a fastening strip 11 for fixing the straight strip 8 and the test tube 14. A plurality of limit blocks 12 are designed on both sides of the lower end of the straight strip 8. A limit groove 13 is provided between these limit blocks 12, and the upper end of the fastening strip 11 can be stuck in the limit groove 13. By adjusting the position of the fastening strip 11 in the limit groove 13, the curvature of the elastic strip 9 can be adjusted, thereby adjusting the squeezing force of the test tube 14, so that it fits tightly on the wall of the heating water tank 7.

[0024] The straight strip 8, the elastic strip 9 and the fastening strip 11 are all made of compression-resistant metal materials to withstand high temperatures and mechanical stress. The cross-sections of the straight strip 8, the elastic strip 9 and the fastening strip 11 are all designed to be "U" shaped to improve structural strength and stability; the elastic strip 9 and the detour 10 are designed as one piece, and the cross-section thereof is "Ω" shaped to increase elasticity. The connection between the elastic strip 9 and the straight strip 8 is designed to be arc-shaped to make a smooth transition and reduce stress concentration; the surface of the elastic strip 9 is covered with a high-temperature resistant rubber gasket, through which the elastic strip 9 can fit tightly on the wall of the heating water tank 7, while preventing the high temperature from damaging the elastic strip 9. The elastic strip 9 is tightly attached to the heating water tank 7 through the gasket to prevent the elastic strip 9 from sliding and improve the stability; the surface of the straight strip 8 is also provided with a high-temperature resistant rubber strip, and the openings on these rubber strips are directly opposite to the circular holes on the end face of the straight strip 8 to ensure that the test tube 14 can be closely contacted with the rubber strip when inserted, so as to improve the sealing and stability; a plurality of limit blocks 12 are equidistantly distributed at the lower end of the straight strip 8, which are used to limit the position of the straight strip 8 and the test tube 14. The surfaces of the limit blocks 12 and the fastening strip 11 are provided with rubber blocks, through which the fastening strip 11 can be more firmly stuck at the limit blocks 12, ensuring the stability and reliability of the entire structure.

[0025] Working process: Before starting the electric thermostatic water tank, first make sure that all components are in the correct position and well connected. Key components such as the circulating water pump 2 and the heater 5 should be in standby state; driven by the circulating water pump 2, water is pumped out of the electric thermostatic box 1 and flows through the circulation pipe 3. The valve 4 controls the switch and flow rate of the water flow to ensure that the water flows smoothly in the circulation loop; the heater 5 starts working to provide continuous heating for the water flow in the electric thermostatic box 1. By continuously heating and adjusting the temperature, the electric thermostatic water tank maintains the water temperature constant at the set value; after the water flows through the electric thermostatic box 1, it enters the thermostatic water tank 6 and is further heated by the heating water tank 7. The straight bar 8 and the test tube 14 inside the heating water tank 7 play a role in uniform heating; the test tube 14 is inserted into the round hole of the heating water tank 7, and the fixing and squeezing force of the straight bar 8, the elastic bar 9 and the fastening bar 11 ensure that the test tube 14 is tightly fitted on the wall of the heating water tank 7 to achieve uniform heating; by adjusting the position of the fastening bar 11 in the limiting groove 13, the curvature of the elastic bar 9 can be adjusted, thereby adjusting its squeezing force on the test tube 14. This adjustment ensures the stability and uniformity of the test tube 14 during the heating process; during the working process, the electric thermostatic water tank needs to continuously monitor the water temperature, and adjust the heater 5 and the circulating water pump 2 to keep the water temperature constant within the set range; when the electric thermostatic water tank completes the heating task or needs to stop working, turn off the heater 5 and the circulating water pump 2, disconnect the power supply, and clean the working area to ensure the safety and cleanliness of the equipment.
