DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0024] like Figures 1 to 5As shown, a specific embodiment of the present invention provides an oil film thickness sensor tester, including a detection probe 1 and a wire 2 fixedly connected to the detection probe 1, a reagent tube 3 is slidably connected to the detection probe 1, and a solution cavity 4 for accommodating a cleaning agent is opened in the inner cavity of the reagent tube 3; the reagent tube 3 and the solution cavity 4 are provided so that the cleaning agent can be placed inside the solution cavity 4, and the reagent tube 3 is provided on the outside of the detection probe 1, so as to facilitate the cleaning of the detection position of the end when using or maintaining the detection probe 1, simplify the maintenance process, and avoid forgetting or losing the cleaning agent. A spray component for the cleaning agent to overflow is provided on the reagent tube 3, and the cleaning agent stored in the solution cavity 4 can be discharged outward by providing the spray component. The invention also includes a movable component provided at the bottom end of the conduit 6 for accurately spraying the cleaning agent to the detection position of the end of the detection probe 1, and the movable component can cooperate with the spray component to make the cleaning agent accurately sprayed to the detection position of the end face of the detection probe 1, and during the normal use of the detection probe 1, the various components will not affect its normal operation.

[0025] like Figures 2 to 5 As shown, specifically, the spray assembly includes a piston plate 5 slidably connected in the solution chamber 4 for pushing the cleaning agent, a conduit 6 for discharging the cleaning agent outward is fixedly connected to the reagent tube 3, a push rod 7 is fixedly connected to the piston plate 5, and a pressure plate 8 is fixedly connected to the push rod 7 for cooperating with the push rod 7 to push the piston plate 5 to move in the solution chamber 4, and the wire 2 movably passes through the pressure plate 8, and the pressure plate 8 is close to the inner wall of the solution chamber 4, and an isolation plate 9 for blocking the cleaning agent is slidably connected in the solution chamber 4. A discharge port 10 is formed at the connection between the conduit 6 and the reagent tube 3, and the discharge port 10 is used for the isolation plate 9 to cooperate with the control of the discharge of the cleaning agent. First, after the cleaning agent is stored in the solution chamber 4, the cleaning agent is between the piston plate 5 and the isolation plate 9 at the bottom, and the piston plate 5 and the isolation plate 9 are in close contact with the inner wall of the solution chamber 4. When the cleaning agent is used, the cleaning agent inside it cannot flow out. When cleaning and maintaining the detection position of the end face of the detection probe 1, the pressure plate 8 at the top is pushed and pressed, and the piston plate 5 at the bottom moves downward inside the solution chamber 4 through the push rod 7. At this time, since there is cleaning agent between the bottom end of the piston plate 5 and the isolation plate 9, the isolation plate 9 at the bottom is subjected to pressure through the cleaning agent as the medium. A spring 11 and a telescopic rod 12 are fixedly connected between the isolation plate 9 and the bottom end of the solution chamber 4. When the spring 11 is stationary and not under force, the bottom end surface of the isolation plate 9 at the top is higher than the position of the discharge port 10. At this time, the pressure on the isolation plate 9 cannot cause the spring 11 and the telescopic rod 12 at the bottom to be forced to contract, and the isolation plate 9 remains stationary. At this time, the spring 11 and the telescopic rod 12 are under pressure and the reagent tube 3 is under pressure.

[0026] like Figures 2 to 5As shown, specifically, a guide groove 18 is provided on the detection probe 1, and a magnetic block 19 is provided on the reagent tube 3. A metal sheet for adsorbing the magnetic block 19 is provided at the end of the guide groove 18. The width of the guide groove 18 gradually decreases from bottom to top, and a rubber pad is provided on the side of the guide groove 18. The magnetic block 19 can produce an adsorption effect with the metal sheet, so that the position of the reagent tube 3 on the detection probe 1 is maintained stable under the action of the adsorption force. At this time, the reagent tube 3 is subjected to the pressure applied in the above process, thereby overcoming the adsorption force and causing the reagent tube 3 to move downward on the detection probe 1. The magnetic block 19 breaks away from the metal sheet and moves downward in the guide groove 18 until it moves to the bottom end of the guide groove 18. The movable component includes an movable member rotatably connected to the conduit 6 for changing the spraying position of the cleaning agent. The movable tube 13 and the guide tube 6 are fixedly connected with a connecting plate 14, and a tension spring 15 is movably connected between the connecting plate 14 and the protrusion on the movable tube 13. A bending head 16 for spraying the cleaning agent outward is fixedly connected to the movable tube 13. A convex ring 17 for limiting the piston plate 5 is provided at the opening of the reagent tube 3. At this time, the movement of the reagent tube 3 drives the guide tube 6 and the movable tube 13 to move downward, and the bending head 16 moves downward close to the outer surface of the detection probe 1 until the magnetic block 19 on the reagent tube 3 cannot move under the limiting action of the bottom end of the guide groove 18, and its movable tube 13 cannot move. At this time, the movable tube 13 is separated from the detection probe 1, so that it rotates on the guide tube 6 under the tension of the tension spring 15, and the rotation causes the bending head 16 to align with the detection probe 1. At the measuring end surface, the pressure plate 8 is continued to be pushed downward. Since the reagent tube 3 cannot continue to move downward under the limiting action, the piston plate 5 pushes the cleaning agent under the action of gradually increasing thrust, so that the isolation plate 9 at the bottom moves downward, pushing the spring 11 and the telescopic rod 12 at the bottom to contract and generate a reaction force. The isolation plate 9 moves downward and its position gradually becomes lower than the height of the discharge port 10, so that the cleaning agent in the solution cavity 4 can enter the conduit 6 through the discharge port 10 under the continuous pressure of the piston plate 5, and spray to the detection end surface of the detection probe 1 through the movable tube 13 and the bending head 16, so that it can be cleaned. After the cleaning maintenance is completed, the pressure plate 8 is stopped, so that the isolation plate 9 is no longer under pressure. At this time, under the action of the spring 11 Under the reaction force, the isolation plate 9 moves upward and resets, so that the position of the bottom end surface of the isolation plate 9 is higher than the position of the discharge port 10, so that the cleaning liquid inside the solution chamber 4 cannot be discharged outward, and then the reagent tube 3 is pulled to move upward on the detection probe 1, and the magnetic block 19 moves upward in the guide groove 18 and resets and adsorbs with the metal sheet again, so as to keep the reagent tube 3 stable on the detection probe 1. The guide groove 18 is gradually narrowed from bottom to top, so that the magnetic block 19 is gradually subjected to the clamping force when it moves upward and resets in cooperation with the rubber pad, so that the magnetic block 19 strengthens its stability when it moves to the top position of the guide groove 18, and in the process of the reagent tube 3 moving upward, the movable tube 13 is blocked and squeezed by the outer side of the detection probe 1.This causes the movable tube 13 to rotate and reset, and makes the movable tube 13 close to the outer side of the detection probe 1. The rotating movable tube 13 causes the tension spring 15 to be stretched and generate a reaction force. The generated reaction force provides the force for the movable tube 13 to rotate when it separates from the outer side of the detection probe 1 during the above process.
