[0021] Example 1

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The test chamber shown includes a horizontal chamber 100, a test chamber 101 disposed within the horizontal chamber 100, a plate-type partition 102 disposed within the test chamber 101, a heating element mounting groove 110 and a sensor mounting groove 111 disposed within the bottom surface of the horizontal chamber 100, and a live wire heating element 112 and a signal wire temperature sensor 113 respectively mounted on the bottom surface of the horizontal chamber 100 via the heating element mounting groove 110 and the sensor mounting groove 111, and respectively disposed within the heating element mounting groove 110 and the sensor mounting groove 111. The first sealing ring 114 and the second sealing ring 115, which are used in conjunction with the live wire heating part 112 and the signal wire temperature sensor 113 in the heat mounting slot 110 and the sensor mounting slot 111, and the box cover 106 set on the horizontal box 100, the strip horizontal plate seat 107 set on the horizontal box 100 and located on one side of the test tank 101, and the PLC controller 108 with display and the control board 109 with power button set on the strip horizontal plate seat 107;

[0023] The PLC controller 108 with display is connected to the temperature sensor 113 with signal line, the control board 109 with power button, and the heating part with live wire 112. The control board 109 with power button is connected to the heating part with live wire 112.

[0024] The PLC controller 108 with display receives the temperature of the deionized water in the test tank 101 (all shown in the figure, but not affecting the disclosure of the technical solution of this application), the operating status parameter signal of the power button control board 109, and the operating status parameter signal of the power wire heating unit 112, respectively fed back by the temperature sensor 113 with signal line, the control board 109 with power button, and the heating unit 112 with live wire. The temperature sensor 113 with signal line is used to detect the temperature of the deionized water in the test tank 101. The heating unit 112 with live wire is used to heat the deionized water in the test tank 101. The power button control board 109 is connected to an external power supply (all shown in the figure, but not affecting the disclosure of the technical solution of this application) to supply power to the heating unit 112 with live wire.

[0025] The working principle is as follows:

[0026] (1) First, add the deionized water for the test into the test tank 101 and cover the tank with the lid 106;

[0027] (2) Then, turn on the control board 109 with power button to supply power to the live wire heating part 112, and then use the PLC controller 108 with display to control the live wire heating part 112 (intelligent type) to work, and at this time heat the ionized water.

[0028] (3) Finally, during the heating process, the temperature sensor 113 with signal line transmits the temperature of deionized water to the PLC controller 108 with display in real time.

[0029] When the preset constant temperature test value is reached by the PLC controller 108 with display, the PLC controller 108 with display controls the heating part 112 with live wire to stop heating; when the deionization temperature value fed back by the temperature sensor 113 with signal line is lower than the preset constant temperature test value, the PLC controller 108 with display controls the heating part 112 with live wire to start heating.

[0030] Once the required test temperature is reached, lift the lid 106 out of the horizontal chamber 100 and immerse the product to be tested in deionized water before closing the lid 106. At this time, the test product is placed on the plate mesh 102.

[0031] Example 2

[0032] Based on Embodiment 1, the test chamber further includes limiting slots 121 symmetrically arranged on one side of the horizontal chamber 100 and located in the four corners of the test groove 101, and limiting protrusions 122 arranged at the four corners of one side of the chamber cover 106 and used in conjunction with the limiting slots 121.

[0033] The limiting slot 121 and the limiting protrusion 122 are used in combination in a circular or polygonal structure.

[0034] After the lid 106 is closed, the lid 106 and the horizontal box 100 can be quickly aligned and matched, and the lid 106 can also be used to prevent the box from falling, thus meeting the safety requirements of the test.

[0035] Example 3

[0036] Based on Embodiment 1 or Embodiment 2, the test chamber further includes a cover protrusion 119 disposed on one side of the cover 106, and a rubber sealing ring 120 fitted on the cover protrusion 119.

[0037] This achieves a seal between the lid 106 and the horizontal housing 100, preventing heat leakage.

[0038] Example 4

[0039] Based on Embodiment 1, Embodiment 2, or Embodiment 3, the test chamber further includes hydraulic cylinder seats 103 symmetrically arranged on the outer walls at both ends of the horizontal chamber 100, hydraulic cylinder fixing sleeves 104 symmetrically arranged on the outer walls at both ends of the horizontal chamber 100 and located above the hydraulic cylinder seats 103, vertical hydraulic cylinders 105 installed on both sides of the horizontal chamber 100 through the hydraulic cylinder seats 103 and the hydraulic cylinder fixing sleeves 104, chamber cover through holes 116 symmetrically arranged in both ends of the chamber cover 106, screws 117 respectively arranged on the vertical hydraulic cylinders 105 and used in conjunction with the chamber cover through holes 116, and screw nuts 118 arranged on the screws 117.

[0040] The purpose of the above structural design is to enable the lid 106 to be quickly lifted and positioned in the air, while also allowing operation without approaching the horizontal chamber 100. This solves the problems of the lid 106 becoming too hot to lift manually during the test, and the lid 106 being difficult to place properly (random placement also poses a safety hazard). In addition, the manual lid 106 requires approaching the horizontal chamber 100 for operation, and hot steam also poses a safety hazard (this solves the problem of hot steam causing injury).

[0041] Example 5

[0042] Based on Embodiment 1, Embodiment 2, Embodiment 3, or Embodiment 4, the test chamber further includes an ion water drain port 123 disposed in the lower part of the horizontal chamber 100 and used in conjunction with the test tank 101, and a valved drain pipe 124 disposed on the horizontal chamber 100 and used in conjunction with the ion water drain port 123.

[0043] This allows for rapid discharge after the experiment is completed or when deionized water needs to be replaced.

[0044] In the test chamber of this structure, the vertical hydraulic cylinder 105, the PLC controller 108 with display, the control board 109 with power button, the heating element with live wire 112, and the temperature sensor 113 with signal line are all conventional components or devices. These will not be described in detail in this application.

[0045] It should be noted that, in this document, terms such as "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
