Description

Technical Field

[0001] The invention belongs to the technical field of turbidity detection, in particular to an integrated turbidity sensor. Background Art

[0002] Turbidity sensors are installed in washing machines and dishwashers. They are used to detect the water after washing in washing machines and dishwashers. The infrared module can detect the content of objects in the water, and the current water cleanliness is determined by the content of objects. The detection signal is output to the control module of the washing machine and dishwasher. The washing machine and dishwasher use this as a judgment condition to adjust the cleaning time.

[0003] A patent application with the existing publication number CN115406867A discloses a turbidity sensor with integrated temperature detection, which includes a transparent housing assembly, which includes a transparent housing, a transparent inner housing, and an O-ring A; a PCB assembly inserted into the transparent housing assembly, which includes a PCB board, a light pipe bracket, an infrared transmitting tube, an infrared receiving tube, and a thermistor NTC. By providing a transparent inner housing with a lens and a prism and a thermistor NTC on the PCB board, the turbidity sensor has the function of detecting the degree of water turbidity and temperature.

[0004] During use, the above-mentioned technical solution detects turbidity through infrared transmitting tubes and receiving tubes. However, the infrared transmitting tubes and receiving tubes will generate heat during the detection process, and the heat will affect their thermistors, causing the detected temperature to deviate from the actual temperature in the water. In addition, scale and dirt may adhere to the surface of the transparent shell after use. As scale and dirt accumulate, the detection of the infrared transmitting tubes and receiving tubes will be affected.

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

An NTC thermistor 25 is arranged inside the measuring chamber 121, and the NTC thermistor 25 is welded on the surface of the PCB board 2 on the opposite side of the infrared receiving module 22. The interior of the measuring chamber 121 is filled with thermal conductive resin. A 3-pin needle seat 21 is installed on one side of the top of the PCB board 2, and the 3-pin needle seat 21 runs through the inside of the top cover 11. Two TDS probes 24 are arranged on the side of the PCB board 2 away from the infrared receiving module 22. The TDS probes 24 are inserted into the inside of the transparent housing 1, and a 2-pin plug 241 is arranged above the TDS probe 24. The PCB board 2 is close to the 2p A 2pin needle seat 242 is welded on one side of the in plug 241, and the 2pin plug 241 and the 2pin needle seat 242 are plugged and connected; a support plate 3 is fixed on the side of the transparent shell 1 close to the TDS probe 24, a first micro motor 31 is installed on the top of the support plate 3, a support column 32 is fixed on the bottom of the support plate 3, a threaded rod 312 is arranged on the side of the support column 32 close to the TDS probe 24, the threaded rod 312 is rotatably connected to the inside of the support plate 3, a gear is fixed on the outside of the rotating shaft of the first micro motor 31, a toothed disc is fixed on the top of the threaded rod 312, the gear of the first micro motor 31 is meshed with the toothed disc of the threaded rod 312, and the support column 32 slides close to the side of the TDS probe 24 A sliding seat 331 is connected, and the sliding seat 331 is threadedly connected to the threaded rod 312. A lifting seat 33 is fixed to the side of the sliding seat 331 away from the support column 32. The top ends of the two TDS probes 24 are fixed inside the lifting seat 33. A foam 342 is arranged below the lifting seat 33, and the foam 342 is sleeved on the outside of the TDS probes 24. Connecting frames 371 are fixed to both sides of the sliding seat 331. A wiping strip 37 is arranged on the side of the first measuring chamber 12 close to the second measuring chamber 13. A wiping strip 37 is also arranged on the side of the second measuring chamber 13 close to the first measuring chamber 12. The bottom end of the connecting frame 371 is fixedly connected to the wiping strip 37, and the wiping strip 37 is closely attached to the surfaces of the first measuring chamber 12 and the second measuring chamber 13.

[0033] Before using the washing machine or dishwasher, the sensor needs to be installed in the installation position reserved inside it, and the connector is plugged into the inside of the 3pin needle seat 21. At this time, the control board of the washing machine and the dishwasher is connected to the PCB board 2 through the 3pin needle seat 21. During the cleaning process, the inside of the washing machine or the dishwasher is filled with water. During the cleaning process, the infrared transmitting module 23 is controlled to emit infrared light, and then the infrared receiving module 22 receives the infrared light. The infrared light will be blocked by the dirt in the water when passing through the water. The current dirt content in the water can be judged by the amount of light entering the infrared receiving module 22. The NTC thermistor 25 can also detect the temperature in the water. The temperature of the incoming water can be controlled in real time by the detected temperature. The measuring room 121 is sealed with a thermally conductive resin to prevent the temperature generated during the working process of the infrared receiving module 22 and the infrared transmitting module 23 from affecting the temperature detection. At the same time, a TDS probe 24 is set to detect the substances dissolved in the water. However, after long-term use, scale and dirt may adhere to the surface of the TDS probe 24, which will affect the detection of the TDS probe 24, so it needs to be cleaned regularly. After a period of use, the first micro motor 31 is started to drive the threaded rod 312 to rotate. At this time, the threaded rod 312 rotates to drive the sliding seat 331 to move upward. The support column 32 can guide the sliding seat 331. The sliding seat 331 will drive the lifting seat 33 to move at the same time during its rise. The lifting seat 33 draws the TDS probe 24 into the interior of the transparent housing 1. During this process, the TDS probe 24 will pass through the interior of the foam 342. The foam 342 can scrape the scale and dirt on the surface of the TDS probe 24 to the outside of the transparent housing 1. After scraping, the first micro motor 31 is started to drive the threaded rod 312 to rotate. At this time, the threaded rod 312 rotates to drive the sliding seat 331 to move upward. The support column 32 can guide the sliding seat 331. The sliding seat 331 will drive the lifting seat 33 to move at the same time during its rise. The lifting seat 33 draws the TDS probe 24 into the interior of the transparent housing 1. During this process, the TDS probe 24 will pass through the interior of the foam 342. The foam 342 can scrape the scale and dirt on the surface of the TDS probe 24 to the outside of the transparent housing 1. The reverse rotation of the micro motor 31 can drive the TDS probe 24 to return to its original position. During use, dirt may adhere to the surfaces of the first measuring chamber 12 and the second measuring chamber 13, which will cause the turbidity detected by the sensor to deviate. Therefore, when the sliding seat 331 moves up and down, the connecting frame 371 will move at the same time. At this time, the connecting frame 371 drives the wiping strip 37 to move on the surfaces of the first measuring chamber 12 and the second measuring chamber 13, which can scrape off the dirt on the surfaces of the first measuring chamber 12 and the second measuring chamber 13, and can prevent the dirt from adhering to affect the detection accuracy of the sensor.

[0034] like Figure 5 to Figure 6 As shown, a fixing block 34 is fixed to the bottom end of the transparent housing 1, and two rotating shells 341 are rotatably connected inside the fixing block 34, and the foam 342 is fixed inside the rotating shell 341. The bottom end of the threaded rod 312 extends inside the fixing block 34, and a gear is fixed to the bottom end of the threaded rod 312, and the gear is meshed and connected with the two rotating shells 341;

[0035] When the threaded rod 312 rotates, the gear at the bottom will rotate, and the gear will drive the two rotating shells 341 to rotate simultaneously. The rotating shells 341 drive the foam 342 to scrape the TDS probe 24 longitudinally and transversely at the same time, which can enhance the cleaning effect of the foam 342 on the TDS probe 24.

[0036] like Figure 5 to Figure 6 As shown, the inner diameter of the foam 342 is smaller than the outer diameter of the TDS probe 24, and the inner side of the foam 342 is provided with textures;

[0037] The small inner diameter of the foam 342 allows it to fit closely to the outside of the TDS probe 24, making it easier to scrape off dirt on the surface of the TDS probe 24. The internal texture of the foam 342 can enhance the friction between the foam 342 and the TDS probe 24, thereby enhancing the scraping effect.

[0038] like Figures 3 to 7 As shown, a support base 35 is provided below the 2-pin plug 241, the bottom end of the support base 35 is fixedly connected to the transparent housing 1, a rotating rod 351 is rotatably connected inside the support base 35, a connecting plate 352 is fixed to the top of the rotating rod 351, a power connection frame 355 is fixed to the side of the top of the support base 35 away from the connecting plate 352, and the 2-pin plug 241 is connected to the power connection frame 355 through a wire;

[0039] During use, the 2-pin plug 241 is connected to the connecting plate 352 through the power connection frame 355, and the connecting plate 352 can be connected to the TDS probe 24. In this way, the 2-pin plug 241 is connected to the TDS probe 24. During the cleaning process, the 2-pin plug 241 needs to be disconnected from the TDS probe 24. At this time, the rotating rod 351 drives the connecting plate 352 to rotate so that the connecting plate 352 is separated from the TDS probe 24 and the power connection frame 355 at the same time, and the connection between the TDS probe 24 and the 2-pin plug 241 can be disconnected. After the cleaning is completed, the connecting plate 352 rotates back to its original position, which can make it easier for the TDS probe 24 to move to the transparent housing 1, thereby reducing the influence of the wire on the movement of the TDS probe 24.

[0040] like Figures 5 to 7 As shown, a steering gear 353 is fixed to the outside of the rotating rod 351 between the two connecting plates 352, and a gear block 332 is fixed to one side of the lifting seat 33 close to the steering gear 353, and the gear block 332 can be meshed and connected with the steering gear 353;

[0041] When the TDS probe 24 is extended to the outside of the transparent housing 1, the tooth block 332 is meshed with the steering gear 353, and the connecting plate 352 is connected to the TDS probe 24. When the TDS probe 24 moves to the inside of the transparent housing 1, the tooth block 332 is driven to move upward, and the tooth block 332 drives the steering gear 353 to rotate. When the steering gear 353 rotates 90° and separates from the tooth block 332, the connecting plate 352 can be automatically separated from the TDS probe 24. When the TDS probe 24 returns to its original position, the tooth block 332 can drive the steering gear 353 to rotate 90° in the opposite direction, so that the connecting plate 352 can be automatically connected to the TDS probe 24.

[0042] like Figure 7 As shown, coil springs 356 are fixed to both ends of the rotating rod 351, and the outer side of the coil spring 356 is fixedly connected to the coil spring 356;

[0043] The rotating rod 351 and the support seat 35 can be connected by the coil spring 356. When the steering gear 353 rotates 90°, the coil spring 356 can fix the position of the rotating rod 351, so that the connecting plate 352 can remain vertical to the support seat 35 during the cleaning process of the TDS probe 24, preventing the connecting plate 352 from driving the rotating rod 351 to rotate due to gravity and affecting the resetting of the TDS probe 24.

[0044] like Figure 7 As shown, a spring piece 354 is fixed to one side of the bottom end of the connecting plate 352 close to the TDS probe 24, and a spring piece 354 is also fixed to one side of the bottom end of the power connection frame 355 close to the connecting plate 352;

[0045] The connecting plate 352 and the TDS probe 24 are connected by a spring clip 354, and the connecting plate 352 and the power connection frame 355 are also connected by the spring clip 354. The spring clip 354 is elastic and can always maintain a tight connection between the connecting plate 352 and the TDS probe 24 and the power connection frame 355, thereby preventing poor contact between the TDS probe 24 and the 2-pin plug 241 during use.

[0046] like Figures 3 to 8 As shown, a movable shell 36 is disposed below both sides of the support plate 3, a cotton column 361 is disposed inside the movable shell 36, a liquid storage tank 367 is fixed on the side of the top of the transparent shell 1 away from the support plate 3, and the bottom end of the liquid storage tank 367 is connected to the inside of the movable shell 36 through a conduit;

[0047] After long-term use, the scale attached to the surface of the TDS probe 24 will be difficult to clean. At this time, an acidic solution is needed to dissolve the scale on the surface of the TDS probe 24. At this time, the cotton cylinder 361 is wrapped around the outside of the TDS probe 24 entering the transparent shell 1, and the liquid storage tank 367 inputs the acidic solution into the movable shell 36 through the conduit. The acidic solution soaks the cotton cylinder 361, and the cotton cylinder 361 can dissolve the scale on the surface of the TDS probe 24. When the TDS probe 24 returns to its original position, the foam 342 will rotate in the opposite direction to clean the surface of the TDS probe 24 again. At this time, the dissolved scale will be easier to clean.

[0048] like Figures 3 to 8 As shown, a slider 364 is fixed to the top of the movable shell 36, and guide frames 363 are fixed to both sides of the support plate 3. The slider 364 is slidably connected to the inside of the guide frame 363. A spring 365 is fixed to the side of the slider 364 away from the cotton column 361, and the other end of the spring 365 is fixedly connected to the inner side of the guide frame 363. A guide rod is fixed to the inside of the guide frame 363, and the guide rod runs through the inside of the slider 364 and the spring 365. A pull rope 366 is fixed to the side of the slider 364 close to the spring 365. Pulleys for assisting the movement of the pull rope 366 are provided at the top and bottom of the guide frame 363. The winding wheel 311 is fixed to the end of the rotating shaft of the first micro motor 31, and the other end of the pull rope 366 is fixed to and wound around the outside of the winding wheel 311.

[0049] When the TDS probe 24 extends out of the transparent housing 1, the movable housing 36 is at a position away from the TDS probe 24. At this time, when the TDS probe 24 rises, it can avoid affecting the TDS probe 24. The first micro motor 31 rotates and drives the reel 311 to rotate. The reel 311 unwinds the pull rope 366 on its surface. At this time, the elastic force of the spring 365 pushes the slider 364, and the slider 364 drives the movable housing 36 to move, so that the cotton cylinder 361 gradually approaches the TDS probe 24. After the TDS probe 24 completely enters the interior of the transparent housing 1, the cotton cylinder 361 can be wrapped in the TDS probe 2 4, the dirt on the surface of the TDS probe 24 can be dissolved at this time, when the TDS probe 24 extends out of the transparent shell 1, the reel-up wheel 311 reels the pull rope 366, and the movable shell 36 can be moved to both sides at this time. The area of ​​the TDS probe 24 close to the lifting seat 33 does not need to extend out of the transparent shell 1 during use, so it does not need to be cleaned. The cotton cylinder 361 only wraps the area of ​​the TDS probe 24 extending out of the transparent shell 1. During the separation process of the cotton cylinder 361 and the TDS probe 24, the area of ​​the TDS probe 24 that does not need to be cleaned can be used as a buffer zone to prevent the movable shell 36 from interfering with the movement of the lifting seat 33.

[0050] like Figures 3 to 8As shown, a steering gear ring 362 is fixed to the top of the cotton cylinder 361, a second micro motor 313 is installed at the top of the support plate 3, transmission rods 314 are arranged on both sides of the second micro motor 313, the transmission rod 314 is rotatably connected to the inside of the support plate 3, gears are fixed to the top and bottom of the transmission rod 314, a gear is also fixed to the end of the rotating shaft of the second micro motor 313, the gear of the second micro motor 313 is meshed and connected with the gear at the top of the transmission rod 314, and the gear at the bottom of the transmission rod 314 can be meshed and connected with the steering gear ring 362;

[0051] During use, the cotton cylinder 361 can only dissolve a partial area of ​​the TDS probe 24. Therefore, when the cotton cylinder 361 moves to wrap the outside of the TDS probe 24, the steering gear ring 362 is meshed with the gear at the bottom end of the transmission rod 314, and then the second micro motor 313 drives the steering gear ring 362 to rotate through the transmission rod 314. At this time, the steering gear ring 362 drives the cotton cylinder 361 to rotate. At this time, the cotton cylinder 361 can completely apply the acidic solution to the surface of the TDS probe 24, which can make the surface of the TDS probe 24 clean better.
