Description

Technical Field

[0001] This utility model relates to the field of conductivity testing technology, and in particular to a conductivity testing device. Background Technology

[0002] Conductivity testing typically involves measuring the conductivity of solutions. In existing technologies, the conductivity of solutions is highly temperature-dependent. The solution to be tested usually needs to be kept at a constant temperature of 25°C in a water bath or oven before the conductivity meter probe is inserted into the solution for reading. However, to improve accuracy, the sample cups used to hold the solution need to be manually cleaned during conductivity testing. Furthermore, existing technologies require transferring the cleaned sample cups from the oven or water bath to the conductivity meter's operating platform for testing. Therefore, the conductivity testing process in existing technologies is cumbersome and inefficient.

[0003] To address the aforementioned technical issues, Chinese utility model patent ZL202223185344.3 (authorization announcement number CN218886027U) discloses a testing device for the conductivity of a conductive agent. This testing device includes a housing, an internal testing chamber, a heating plate on the bottom of the testing chamber, testing heads in the middle of the left and right side walls of the testing chamber, a housing cover on the top of the housing, and detectors on the outside of the housing, with the detectors connected to the two testing heads via cables.

[0004] Although the conductivity testing device for conductive agents is connected to the detection module via a detection head and cables, and the detection module processes the detection information and displays it on a screen, allowing staff to intuitively observe the conductivity data, the device has the following limitations: the conductive agent (i.e., the solution to be tested) is placed in the detection chamber. If different types of conductive agents are to be tested, the entire detection chamber needs to be manually cleaned. Since there is no dedicated cleaning channel for the detection chamber, cleaning becomes difficult, making it unsuitable for testing the conductivity of different types of conductive agents. Therefore, further improvements to the existing technology are needed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a conductivity testing device that facilitates cleaning of the testing chamber, in light of the above-mentioned prior art.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a conductivity testing device, comprising:

[0007] The testing chamber contains the solution;

[0008] The test piece includes a test head that extends into the test chamber and is used to detect the conductivity of the solution;

[0009] Its features also include:

[0010] A washing solution tank, which stores washing solution, is connected to the test chamber via a washing pipe, and the washing solution tank supplies washing solution to the test chamber through the washing pipe;

[0011] The waste liquid tank, connected to the test chamber, is used to recover the solution and cleaning fluid discharged from the test chamber.

[0012] A water pump is installed on the cleaning pipe to provide power.

[0013] To improve the cleaning effect of the test chamber, the outlet of the cleaning pipe is equipped with a spray assembly located inside the test chamber.

[0014] In order to discharge waste liquid (i.e., the solution and cleaning liquid in the test chamber), the test chamber is located above the waste liquid tank, and the top of the waste liquid tank is provided with a drain hole that can communicate with the test chamber. The top of the waste liquid tank is provided with a sealing component and a driving component that is driven to drive the sealing component. The sealing component can be slidably constrained at the bottom of the test chamber, thereby opening or closing the drain hole.

[0015] To make the structure more compact, the washing liquid tank is arranged side by side with the waste liquid tank.

[0016] To enable automated display, a controller electrically connected to the test piece is also included, and the controller is also electrically connected to the display module.

[0017] Preferably, the drive unit is electrically connected to the controller.

[0018] To heat the solution, a heating chamber is provided above the waste liquid tank, and the test chamber is placed inside the heating chamber.

[0019] Furthermore, the heating chamber is equipped with a heating element, which is electrically connected to the controller. The controller is also electrically connected to a temperature detection module, which is used to detect the temperature of the solution in the test chamber.

[0020] Preferably, the controller is electrically connected to the water pump.

[0021] Compared with existing technologies, the advantages of this invention are as follows: By setting up a washing solution tank and a waste solution tank, and connecting the washing solution tank to the test chamber via a cleaning pipe, the washing solution tank can supply cleaning solution to the test chamber through the cleaning pipe after the conductivity test is completed, thereby achieving automatic cleaning of the test chamber; in addition, the waste solution tank recovers the solution and cleaning solution discharged from the test chamber. Therefore, the test chamber can be automatically cleaned after the conductivity test, facilitating the next solution conductivity test, avoiding the influence of residual solution on the next solution conductivity test, and improving the accuracy of conductivity testing.

[0023] Figure 2 This is a control block diagram of the conductivity testing device in an embodiment of the present invention. Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1 and Figure 2 As shown, the conductivity testing device in this embodiment includes a test chamber 1, a test piece 2, a washing liquid tank 3, and a waste liquid tank 5.

[0026] Test chamber 1 contains solutions, such as Figure 1 As shown, in this embodiment, the test chamber 1 is a cup-shaped structure with an open top; the test piece 2 includes a test head 21 extending into the test chamber 1; the test head 21 is used to detect the conductivity of the solution, and in this embodiment, the test piece 2 is a conductivity test rod; the washing solution tank 3 stores the washing solution, and the washing solution tank 3 is connected to the test chamber 1 through a washing pipe 4, through which the washing solution tank 3 supplies the washing solution to the test chamber 1 (in this embodiment, the washing solution is pure water); the waste liquid tank 5 is connected to the test chamber 1 and is used to recover the solution and washing solution discharged from the test chamber 1.

[0027] A water pump 6 is installed on the cleaning pipe 4; a spray assembly 7 located inside the test chamber 1 is installed at the outlet of the cleaning pipe 4. In this embodiment, the water pump 6 provides power so that the cleaning solution tank 3 can supply cleaning solution to the test chamber 1 under the action of the water pump 6; the spray assembly 7 adopts existing technology and will not be described in detail here. The spray assembly sprays and cleans the inner wall of the test chamber 1, thereby improving the cleaning effect of the test chamber 1.

[0028] Test chamber 1 is located above waste liquid tank 5, and washing liquid tank 3 is arranged side by side beside waste liquid tank 5. Furthermore, to facilitate the recycling of waste liquid (i.e., solution and cleaning liquid), the top of waste liquid tank 5 is equipped with a drain hole 51 that communicates with test chamber 1. The top of waste liquid tank 5 is equipped with a sealing element 52 and a driving element 53 that is slidably connected to the sealing element 52. The sealing element 52 can be slidably constrained at the bottom of test chamber 1, thereby opening or closing the drain hole 51. The sealing element 52 is a sealing block, and the driving element 53 is a drive motor. This arrangement allows the drain hole 51 to be sealed during the conductivity test phase; after the conductivity test is completed and the solution needs to be replaced, the drain hole 51 is opened by sliding the sealing block, allowing the solution from test chamber 1 to flow from the drain hole 51 into waste liquid tank 5 for recycling.

[0029] In order to test the effect of temperature on conductivity, a heating chamber 10 is provided above the waste liquid tank 5. The test chamber 1 is placed inside the heating chamber 10, and a heating element 11 is provided inside the heating chamber 10. In this embodiment, the heating element 11 is a heating tube.

[0030] To achieve automated control, this embodiment also includes a controller 8 electrically connected to the test piece 2. The controller 8 is also electrically connected to a display module 9, which is a display screen. The operator can visually view the conductivity test structure on the display screen. In addition, the aforementioned drive component 53, heating component 11, and water pump 6 are all electrically connected to the controller 8. The controller 8 is also electrically connected to a temperature detection module 12, which is used to detect the temperature of the solution in the test chamber 1. The controller 8 is configured to control the heating component 11 to perform corresponding heating actions based on the detection results of the temperature detection module 12, so as to stabilize the temperature in the test chamber 1 at the set temperature.

[0031] The working process of the conductivity testing device in this embodiment is as follows:

[0032] Before testing, the drain hole 51 is blocked by the sealing component 52, the solution to be tested is poured into the test chamber 1, and the heating component 11 is controlled to heat the solution in the test chamber 1 through heat exchange. When the temperature detection module 12 detects that the temperature of the solution in the test chamber 1 is stable at the set temperature (25 degrees Celsius), the test component 2 is inserted into the test chamber 1, and the conductivity of the current solution is tested through the test head 21.

[0033] Once the conductivity test of the current solution is completed, the drain hole 51 is opened by controlling the sliding of the sealing component 52, so that the solution in the test chamber 1 flows into the waste liquid tank 5 for recycling. Then, the water pump 6 is started, and the cleaning solution (pure water) in the washing tank 3 is sprayed and cleaned on the inner wall of the test chamber 1 through the spray assembly 7 on the cleaning pipe 4. The cleaning solution after spraying and the solution on the inner wall of the test chamber 1 both flow into the waste liquid tank 5 through the drain hole 51.

[0034] This setting automatically cleans the test chamber walls after a conductivity test, facilitating the next solution conductivity test and preventing residual solution from affecting subsequent tests, thus improving the accuracy of conductivity testing.

However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings.
