[0025] Example

[0026] like Figure 1-4As shown, this embodiment provides a medical temperature controller simulated load test device, including an electrical control box 100 and a load test device 200. The load test device 200 includes a test frame 21, on which a lifting mechanism 23 is provided. The lifting mechanism 23 is used to drive the test water tank 22 to move up and down. The test water tank 22 has an inlet and outlet 224 on its side. The inlet and outlet 224 are connected to an external water source (such as a faucet) through pipes. Water is added to the test water tank 22 through the inlet to make the test water tank 22 reach a specified weight (50kg±1kg). Multiple temperature probes 4 are provided inside the test water tank 22. A heating element 3 is provided inside the test water tank 22. The electrical control box 100 is connected to the temperature probes 4 and the heating element 3 through wires. After the test water tank 22 is lifted by the lifting mechanism 23, water is introduced through the inlet and outlet 224. After the test water tank 22 reaches the specified weight, it is heated by the heating element 3 to raise the internal water temperature. After reaching a certain stability, it is kept constant for four hours. During this process, the water temperature is detected by the temperature probe 4. The electrical control box 100 receives the data from the temperature probe 4 and obtains the overall test results.

[0027] Specifically, the test water tank 22 includes an inner tank 221, an outer tank 222, and a lid 223. The inner tank 221 is located inside the outer tank 222, and a space is left between the inner tank 221 and the outer tank 222 to form a heat-insulating interlayer 225. The lid 223 is placed on top of the outer tank 222 to seal the test water tank 22. The inlet and outlet 224 penetrates the outer tank 222 and the inner tank 221 and is connected to the inner tank 221. The heating element 3 is embedded in the side of the inner tank 221, and the heating end of the heating element 3 is located inside the inner tank 221. The heating element 3 is an electric heating element 3 in the prior art, such as an electric heating rod. Multiple temperature probes 4 are respectively embedded in the top of the inner tank 221, and the detection end of the temperature probe 4 extends into the interior of the inner tank 221. Multiple temperature probes 4 are evenly distributed inside the inner chamber 221 to detect the temperature at different locations within the inner chamber 221, providing more accurate test data.

[0028] Furthermore, the inner tank 221 has a circulating water inlet 52 and a circulating water outlet 53 at both ends of its side. A circulating water pump 51 is installed inside the insulation layer 225. The two ends of the circulating water pump 51 are connected to the circulating water inlet 52 and the circulating water outlet 53 via pipes. The circulating water pump 51 is electrically connected to the electrical control box 100. The circulating water pump 51 continuously circulates the water inside the inner tank 221, ensuring more uniform mixing and preventing the water temperature near the heating element 3 from being too high and other areas from being too low, which could lead to inaccurate testing.

[0029] Furthermore, the inner tank 221 is internally fixedly connected with multiple circulation baffles 226, which divide the cavity of the inner tank 221 into "S"-shaped water channels 227. The circulation water inlet 52 and circulation water outlet 53 are respectively located at both ends of the water channels 227. The water in the inner tank 221 is circulated by the circulation water pump 51. During the circulation process, the water flows along the direction of the water channels 227, which can make the water flow in the tank more uniform and improve the accuracy of the test.

[0030] Specifically, the lifting mechanism 23 includes a lift and a test platform 24. The lift drives the test platform 24 to move up and down, and the test water tank 22 is located above the test platform 24. In this embodiment, the lift adopts a mechanical lifting structure of the prior art, which is driven by a handwheel 231 for lifting. For example, a worm gear screw jack or other structures that can achieve lifting can be used. The specific structure and working principle will not be described in detail here. The test water tank 22 is initially mounted on the test frame 21. By rotating the handwheel 231, the test platform 24 is driven to rise, thereby lifting the test water tank 22.

[0031] Furthermore, a force sensor is embedded in the surface of the test platform 24, and the force sensor is electrically connected to the electrical control box 100. After the test platform 24 lifts the test water tank 22, the force sensor is subjected to the pressure of the test water tank 22 and detects the weight of the test water tank 22. When the weight of the test water tank 22 reaches the range of 50kg±1kg, water filling is stopped.

[0032] Furthermore, guide shafts 241 are fixedly connected to the bottom perimeter of the test platform 24, and linear bearings 242 are embedded in the bottom of the test frame at positions corresponding to the guide shafts 241. The guide shafts 241 pass through the linear bearings 242. The cooperation of the guide shafts 241 and the linear bearings 242 guides the movement of the test platform 24, preventing misalignment and jamming.

[0033] Specifically, the electrical control box 100 is equipped with a PLC controller, and a touch screen is embedded in the surface of the electrical control box 100. The PLC controller controls the operation of the load testing device 200, and the touch screen facilitates human-machine interaction for operators to set parameters and observe data changes.

[0034] The working principle of this utility model is as follows: rotating the handwheel 231 drives the test platform 24 to rise, lifting the test water tank 22. Water is then introduced through the inlet and outlet 224. When the force sensor embedded in the test platform 24 detects that the weight reaches the range of 50kg±1kg, the water injection stops. At this time, the heating element 3 and the circulating water pump 51 are controlled by the electrical control box 100 to work. The heating element 3 heats the water in the test water tank 22, and the circulating water pump 51 continuously circulates and mixes the water to simulate the working state of a medical temperature controller. The temperature probe 4 continuously detects the water temperature change. After working for a period of time, the data is summarized to determine whether the stability and safety of the temperature control system meet the standards.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit them. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this disclosure.
