Description

Technical Field

[0001] The invention relates to the technical field of liquid concentration detection, in particular to a concentration detection device for cleaning agents. Background Art

[0002] Cleaning agents are specially formulated products used for cleaning through the cleaning process. The main components are usually composed of surfactants, builders and additives. There are many types of cleaning agents. According to the type of dirt removed, they can be divided into heavy-duty cleaning agents and light-duty cleaning agents. During the production and processing of cleaning agents, their concentration needs to be tested to determine whether the quality of the cleaning agent meets the standards.

[0003] In order to prevent the detergent adhering during the previous test from affecting the next test result during the continuous test, the detergent concentration detection device on the market is provided with a toggle member and an energy storage oscillator. The sampling detection head can use the instantaneous impact force after the detergent detection is completed to spin off the detergent adhering to the sampling detection head, so as to reduce the detergent adhering to the sampling detection head. However, during the use of the device, since the detergent contains chemical components, and the detergent on the detection head is spun off by physically removing the liquid, the chemical components of the detergent on the detection head surface cannot be decomposed. As a result, after the detergent on the detection head surface is spun off, the detection head surface is still attached to the detergent components, resulting in incomplete cleaning of the detection head, thereby affecting the subsequent detection of other detergent samples, and there are defects during use.

[0022] The driving mechanism includes a cylinder 4 fixedly mounted on the upper end of the support frame, the lower end of the telescopic rod of the cylinder 4 is rotatably connected to a connecting shaft 5 through a bearing, and the connecting shaft 5 is fixedly mounted at the upper end center of the mounting plate 2, a sleeve 6 is movably sleeved on the outer side of the connecting shaft 5 near its upper end, the inner diameter of the sleeve 6 is equal to the outer diameter of the connecting shaft 5, a pin rod 7 is movably embedded on the inner wall of the sleeve 6, a gasket 8 is fixedly connected to one end of the pin rod 7 away from the connecting shaft 5, and a spring 9 is movably abutted on the side of the gasket 8 away from the pin rod 7.

[0023] A spring 2 10 is fixedly installed at the lower end of the sleeve 6, and the spring 2 10 is movably sleeved on the outer side of the connecting shaft 5. A washer 11 is fixedly connected to the lower end of the spring 2 10. A positioning ring 12 is fixedly sleeved on the outer side of the connecting shaft 5, and the washer 11 is movably sleeved on the outer side of the positioning ring 12. The positioning ring 12 can prevent the washer 11 from moving up and down on the outer side of the connecting shaft 5. A limiting straight groove 13 and a threaded groove 14 are respectively provided at the outer side of the connecting shaft 5 corresponding to the pin rod 7, and the number of the limiting straight grooves 13 and the threaded grooves 14 are both two groups, and are equidistantly distributed around the circumference.

[0024] The limiting straight groove 13 and the threaded groove 14 are connected to each other. The length of the limiting straight groove 13 exceeds the connection between it and the threaded groove 14. A limiting embedding groove 15 is also provided on the outer side of the connecting shaft 5 corresponding to the upper end connection of the limiting straight groove 13 and the threaded groove 14. The limiting embedding groove 15 can limit the direction of the pin rod 7. The lower end of the limiting embedding groove 15 is connected to the threaded groove 14. The pin rod 7 is in sliding contact with the connecting shaft 5 through the limiting straight groove 13, the threaded groove 14 and the limiting embedding groove 15.

[0025] The upper end of the sleeve 6 is fixedly provided with a plurality of convex teeth 16 distributed equidistantly around the circumference, and the lower end of the support frame is fixedly embedded with an annular seat 17 corresponding to the outer side of the cylinder 4, and the lower end of the annular seat 17 is fixedly embedded with a rubber ring 18, and the connection between the convex teeth 16 and the rubber ring 18 is a movable abutment. When the convex teeth 16 abut against the rubber ring 18, the rotation of the sleeve 6 can be restricted.

[0026] Working principle: The personnel first insert the cleaning agent test tube to be tested on the test table 1, and then the cylinder 4 drives the installation plate 2 and the two probes 3 to move downward, and the two probes 3 move downward and are respectively inserted into the cleaning agent test tube and the cleaning cylinder 22. After the cleaning agent concentration detection data is transmitted to the computer, the cylinder 4 drives the two probes 3 to move upward; When the sleeve 6 moves upward with the connecting shaft 5, the multiple protruding teeth 16 at the upper end of the sleeve 6 will press against the rubber ring 18 to limit the rotation of the sleeve 6. At this time, the pin rod 7 is located inside the limiting groove 15. Under the condition that the lower end of the limiting groove 15 is connected with the thread groove 14, the pin rod 7 will enter the thread groove 14 through the limiting groove 15. During this process, the connecting shaft 5 and the mounting plate 2 will rotate. When the pin rod 7 slides from the inside of the thread groove 14 to the lower end of the limiting straight groove 13, the mounting plate 2 and the two probes 3 rotate 180°. Afterwards, when the cylinder 4 drives the two probes 3 to move downward again, the pin rod 7 will move upward inside the limiting straight groove 13. At this time, the connecting shaft 5 and the mounting plate 2 will not rotate. When the pin rod 7 moves to the limiting embedding groove 15 at the upper end of the limiting straight groove 13, the spring 1 9 will drive the pin rod 7 to embed into the limiting embedding groove 15. This reciprocating motion is conducive to alternately cleaning and detecting the two probes 3, so that the probe 3 is always in a clean state before the cleaning agent concentration is detected, avoiding the attachment of cleaning agent components to the outside of the probe 3, and effectively avoiding the cleaning agent components attached to the outside of the probe 3 from affecting the detection data.

[0027] Example 2: Please refer to Figure 6 This embodiment further explains the first embodiment. A plurality of pin balls 19 equidistantly distributed around the circumference are movably embedded inside the connecting shaft 5. A V-shaped spring piece 20 is fixedly installed on the outside of the pin ball 19. The V-shaped spring piece 20 is located inside the connecting shaft 5. One end of the V-shaped spring piece 20 away from the pin ball 19 is fixedly connected to the connecting shaft 5. The outer side of the cylinder 4 is provided with hemispherical embedding grooves 21, the number of which is equal to the number of the pin balls 19. The V-shaped spring piece 20 can drive the pin ball 19 to embed into the hemispherical embedding groove 21, and the pin ball 19 is movably engaged with the cylinder 4 through the hemispherical embedding groove 21.

[0028] In this embodiment: when the sleeve 6 drives the connecting shaft 5 and the mounting plate 2 to rotate through the pin rod 7, the limiting straight groove 13, the threaded groove 14 and the limiting embedding groove 15, the pin ball 19 will rotate out of the hemispherical embedding groove 21 due to the flexibility of the V-shaped spring piece 20, and then be embedded in another hemispherical embedding groove 21 driven by the elasticity of the V-shaped spring piece 20, so that the connecting shaft 5 can be positioned after it rotates, and the probe 3 can be prevented from rotating during the downward movement, thereby effectively enhancing the stability of the probe 3 during the downward movement, and facilitating the probe 3 to smoothly enter the cleaning agent to be detected and the cleaning cylinder 22.

[0029] Example 3: Please refer to Figure 2-Figure 4The present embodiment further explains the first embodiment, the blowing mechanism includes two symmetrically distributed sleeves 23 installed on the outside of the cleaning cylinder 22, and the sleeve 23 is fixedly embedded in the interior of the detection platform 1, and a piston 24 that can move up and down is movably embedded in the sleeve 23, and the lower end of the piston 24 is movably abutted against a spring three 25, and the end of the spring three 25 away from the piston 24 is movably abutted against the sleeve 23, and the spring three 25 can drive the piston 24 to move upward inside the sleeve 23.

[0030] A pressure rod 26 is fixedly embedded at the center of the upper end of the piston 24, and the connection between the pressure rod 26 and the mounting plate 2 is a movable abutment. An exhaust pipe 27 connected to the sleeve 23 is fixedly installed at the lower end of the sleeve 23, and the end of the exhaust pipe 27 away from the sleeve 23 is fixedly connected to the cleaning cylinder 22. An intake pipe 28 connected to the sleeve 23 is fixedly installed on the outer side of the sleeve 23, and both the exhaust pipe 27 and the intake pipe 28 are provided with a one-way valve 29, which can control the flow direction of gas inside the intake pipe 28 and the exhaust pipe 27.

[0031] In this embodiment: when the two probes 3 are moved downward and inserted into the cleaning agent to be detected and the cleaning cylinder 22 respectively, the mounting plate 2 will resist the pressure rod 26 and drive the piston 24 to move downward inside the sleeve 23 through the pressure rod 26. During the downward movement, the piston 24 squeezes the internal gas of the sleeve 23 into the cleaning cylinder 22 through the exhaust pipe 27, so that when the probe 3 is inserted into the cleaning cylinder 22, the clean water in the cleaning cylinder 22 will bubble and surge, which is conducive to the rapid and thorough dissolution of the cleaning agent attached to the surface of the probe 3, so that the cleaning of the probe 3 is more comprehensive; When the probe 3 completes the detection of the cleaning agent concentration, the cylinder 4 drives the mounting plate 2 and the probe 3 to move upward. During the upward movement of the mounting plate 2, the piston 24 moves back and resets under the drive of the compression force of the spring 3 25. During the process of the piston 24 moving back and resets, the gas enters the interior of the sleeve 23 through the air inlet pipe 28. The clean water in the cleaning cylinder 22 will be discharged through the drain pipe at regular intervals, and the water inlet pipe will add a certain amount of clean water into the cleaning cylinder 22 at regular intervals.

[0032] Example 4: Please refer to Figure 8 This embodiment further explains Example 1. A socket 30 is fixedly installed at the center of the lower end of the mounting plate 2, and the connection between the socket 30 and the battery 35 is an electrical connection. A plug 31 is movably inserted inside the socket 30, and a connecting seat 32 is fixedly connected to the lower end of the plug 31. The connection between the connecting seat 32 and the socket 30 is a rotational connection, and the plug 31 can rotate inside the socket 30.

[0033] A spring wire 33 is fixedly embedded at the center of the lower end of the connecting seat 32, and a telescopic tube 34 is movably sleeved on the outer side of the spring wire 33. The telescopic tube 34 can protect the spring wire 33 to prevent the mounting plate 2 from driving the spring wire 33 to twist. The upper end of the telescopic tube 34 is fixedly connected to the connecting seat 32, and the lower end of the telescopic tube 34 is fixedly embedded in the interior of the detection platform 1.

[0034] In this embodiment: during the rotation of the mounting disk 2, the socket 30 will be driven to rotate together. At this time, under the positioning effect of the telescopic tube 34, the plug 31 and the connecting seat 32 do not rotate with the mounting disk 2, which can effectively prevent the spring wire 33 from twisting during the rotation of the mounting disk 2, thereby effectively extending the service life of the spring wire 33.
