Description

Technical Field

[0001] This invention relates to the field of optical inspection, specifically to a device for detecting the cleanliness of bed sheets after washing. Background Technology

[0002] The ATP fluorescence detector is based on the principle of bio-optical luminescence detection. It uses a built-in high-precision intelligent optical sensor to collect and identify fluorescence signals, thereby enabling quantitative detection of dirt residue. The ATP fluorescence detector is a commonly used testing device for checking the cleanliness of washed bed sheets.

[0003] However, in actual testing with existing ATP fluorescence detectors, after sampling, operators must manually break the flow-blocking rod of the ATP swab and repeatedly squeeze the rubber sealing cap at the end of the swab to allow the internal reagent to flow out and wet the sampling cotton head before it can be placed into the ATP fluorescence detector for detection. This entire process relies on manual operation, is cumbersome, and makes the testing inconvenient. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by providing a device for detecting the cleanliness of bed sheets after washing.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cleanliness testing device for bed sheets after washing, comprising an ATP fluorescence detector and an ATP swab. A guide sleeve is provided above the ATP fluorescence detector, and the ATP swab is inserted into the guide sleeve. The guide sleeve is aligned with the detection cavity at the top of the ATP fluorescence detector. A second electric actuator is fixedly installed on the upper edge of one side of the guide sleeve, and an open plate is fixedly installed at the output end of the second electric actuator. Two plate frames are symmetrically and elastically installed on the upper edge of the other side of the guide sleeve. A squeezing plate is fixedly installed at the opposite ends of the two plate frames. Guide wheels are installed on the sides of the two plate frames. A pusher is installed at the rear end of the ATP fluorescence detector, and a control frame is connected to the end of the pusher. The two guide wheels are respectively attached to the front and rear end faces of the control frame. The front and rear end faces of the control frame are wavy. A cover is provided on the top of the ATP fluorescence detector, and an opening device is provided between the cover and the ATP fluorescence detector. A support device is provided at the lower part of the guide sleeve.

[0006] Preferably, a lug extends from the upper edge of the other side of the guide sleeve, and a grooved rod is fixedly installed through the middle of the lug. The plate frame is slidably installed on the outer surface of the grooved rod, and a return spring is fixedly installed between the plate frame and the lug. The grooved rod passes through the inside of the return spring.

[0007] Preferably, the pusher includes a sleeve extending to the upper rear end of the ATP fluorescence detector, a fixing frame is inserted inside the sleeve, a notch is provided at the upper end of the sleeve, the fixing frame extends out from the notch, a first electric push rod is fixedly installed at the rear end of the fixing frame, one side of the output end of the first electric push rod is fixed to the control frame, and the guide sleeve is fixed to the end of the fixing frame.

[0008] Preferably, a top frame is fixedly installed on the other side of the output end of the first electric actuator, a top wheel is installed at the end of the top frame, and a cover opening hook extends from the lower rear edge of the control frame.

[0009] Preferably, the opening component includes a bearing extending from the top of the ATP fluorescence detector, the bearing being located on the side of the cover, a cover shaft being rotatably mounted through the middle of the bearing, one end of the cover shaft being fixed to the cover, and the other end of the cover shaft being coaxially fixedly mounted with an opening gear, a torsion spring being provided between the opening gear and the bearing, the cover shaft passing through the inside of the torsion spring, an opening toothed plate meshing with the side of the opening gear, and the opening toothed plate being slidably connected to the ATP fluorescence detector.

[0010] Preferably, the support includes a bracket elastically mounted on the lower part of the guide sleeve, and an intelligent contact sensor is installed through the end of the bracket.

[0011] Preferably, a shaft bracket is fixedly installed on the lower part of one side of the guide sleeve, and a connecting shaft is rotatably installed through the lower end of the shaft bracket, with the support fixed to the outer surface of the connecting shaft.

[0012] Preferably, a first recess is fixedly installed near the edge of the upper end of the support. A limiting sleeve is rotatably installed inside the first recess. A limiting rod is slidably installed inside the limiting sleeve. The limiting rod extends through the upper end of the limiting sleeve. A second recess is rotatably installed at the upper end of the limiting rod. The side of the second recess is fixed to the guide sleeve. A support spring is wound around the outer side of the limiting rod and the outer side of the limiting sleeve. The two ends of the support spring are fixed to the upper end of the limiting rod and the lower end of the limiting sleeve, respectively.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. Place the ATP swab inside the guide sleeve. At this time, the rubber sealing cap at the top of the ATP swab is located on the outside of the guide sleeve. The intelligent contact sensor on the support contacts the ATP swab and sends a signal, which drives the second electric actuator to work. Then, the second electric actuator drives the opening plate to move laterally, so as to pry the flow-blocking bar on the ATP swab and break it. Then, the guide wheel is rolled along the wave part inside the control frame through the movement control frame, which drives the two plate frames to move towards each other continuously. This drives the two squeezing plates to move towards each other continuously, so as to repeatedly squeeze the rubber sealing cap at the top of the ATP swab, so that the reagent can flow downward and wet the sampling cotton head of the ATP swab. This process does not require manual operation by the testing personnel, thus effectively improving the convenience of testing.

[0014] 2. Once the sampling cotton tip of the ATP swab is wetted, the cap-opening hook on the control frame abuts against the cap-opening toothed plate. Then, the first electric actuator continues to operate, pushing the cap-opening hook upwards, which in turn drives the cap-opening gear to rotate, allowing the cap to flip open. When the cap flips up and disengages from under the guide sleeve, the top wheel on the top frame abuts against the lower end of the support. Then, the first electric actuator continues to operate, pushing the top wheel to push the support, causing the support to rotate around the connecting shaft, allowing the support to disengage from under the guide sleeve. At this point, the ATP swab, no longer supported by the support, slides down and enters the detection chamber at the top of the ATP fluorescence detector under the guidance of the guide sleeve. This process does not require manual operation by the testing personnel, thus further improving the convenience of testing. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] This invention provides a technical solution: such as Figures 1-10The device shown is for detecting the cleanliness of bed sheets after washing. It includes an ATP fluorescence detector 1 and an ATP swab 23. Since sampling via the ATP swab 23 and detection by the ATP fluorescence detector 1 to achieve quantitative detection of dirt residue is an existing and widely used technology, the specific structure of the ATP fluorescence detector 1 and the ATP swab 23 is not described in detail here. A guide sleeve 10 is provided above the ATP fluorescence detector 1. The guide sleeve 10 can limit the ATP swab 23, so that when the opening plate 17 moves the flow-blocking rod 35 on the ATP swab 23, the ATP swab 23 will not shift. This ensures that the opening plate 17 can apply sufficient thrust to the flow-blocking rod 35, causing it to break. The ATP swab 23 is inserted into the guide sleeve 10, which is aligned with the detection chamber at the top of the ATP fluorescence detector 1. This ensures that when the ATP swab 23 falls, it smoothly enters the detection chamber at the top of the ATP fluorescence detector 1 under the guidance of the guide sleeve 10. A second electric actuator 16 is fixedly installed on one upper edge of the guide sleeve 10, and the opening plate 17 is fixedly installed at the output end of the second electric actuator 16. The second electric actuator 16 drives the opening plate 17 to move. Two plate holders 20 are symmetrically and elastically installed on the other upper edge of the guide sleeve 10. The two plate holders 20 are relatively... Both ends are fixedly mounted with extrusion plates 9. Guide wheels 22 are mounted on the sides of both plate frames 20. A pusher is mounted at the rear end of the ATP fluorescence detector 1, and a control frame 8 is connected to the end of the pusher. The two guide wheels 22 are respectively attached to the front and rear end faces inside the control frame 8. The front and rear end faces inside the control frame 8 are wavy, allowing the guide wheels 22 to roll along the wavy surface, thereby driving the two extrusion plates 9 to move continuously towards each other. A cover 2 is provided on the top of the ATP fluorescence detector 1, and an opening device is provided between the cover 2 and the ATP fluorescence detector 1. A support is provided at the lower part of the guide sleeve 10. An ATP swab 23 is placed inside the guide sleeve 10. At this time, the ATP swab 23... The top rubber sealing cap 36 is located just outside the guide sleeve 10. Then, the second electric actuator 16 drives the opening plate 17 to move laterally, so as to pry the flow-blocking rod 35 on the ATP swab 23 and break it. Then, the guide wheel 22 is rolled along the wave part inside the control frame 8 through the movement control frame 8, which drives the two plate frames 20 to move towards each other continuously, thereby driving the two squeezing plates 9 to move towards each other continuously, so as to repeatedly squeeze the rubber sealing cap 36 at the top of the ATP swab 23, so that the reagent can flow downward to wet the sampling cotton head 38 of the ATP swab 23. The process does not require manual operation by the testing personnel, thus effectively improving the convenience of testing.

[0019] A lug 18 extends from the upper edge of the other side of the guide sleeve 10. A grooved rod 21 is fixedly installed through the middle of the lug 18. The lug 18 serves to support the grooved rod 21. The plate frame 20 is slidably installed on the outer surface of the grooved rod 21. The grooved rod 21 serves to guide the plate frame 20. A return spring 19 is fixedly installed between the plate frame 20 and the lug 18. The return spring 19 serves to keep the guide wheel 22 in contact with the control frame 8. The grooved rod 21 passes through the inside of the return spring 19.

[0020] The pusher includes a sleeve 11 extending to the upper rear end of the ATP fluorescence detector 1. A fixing frame 13 is inserted inside the sleeve 11. The sleeve 11 facilitates the flexible disassembly and reassembly of the fixing frame 13. A battery can be installed on the fixing frame 13 for power supply. A notch 14 is provided at the upper end of the sleeve 11. The fixing frame 13 extends out from the notch 14. The notch 14 serves to position the fixing frame 13. A first electric push rod 5 is fixedly installed at the rear end of the fixing frame 13. One side of the output end of the first electric push rod 5 is fixed to the control frame 8. The guide sleeve 10 is fixed to the end of the fixing frame 13.

[0021] A top frame 3 is fixedly installed on the other side of the output end of the first electric actuator 5. A top wheel 4 is installed at the end of the top frame 3. The top frame 3 serves to support the top wheel 4. A cover opening hook 12 extends from the lower rear edge of the control frame 8.

[0022] The opening mechanism includes a bearing 34 extending from the top of the ATP fluorescence detector 1. The bearing 34 is located on the side of the cover 2. A cover shaft 24 is rotatably mounted through the middle of the bearing 34. The bearing 34 serves to support the cover shaft 24. One end of the cover shaft 24 is fixed to the cover 2, and the cover shaft 24 allows the cover 2 to rotate. The cover 2 provides a protective cover. The other end of the cover shaft 24 is coaxially fixed with an opening gear 25. A torsion spring 26 is provided between the opening gear 25 and the bearing 34. The torsion spring 26 closes the cover 2. The cover shaft 24 passes through the inside of the torsion spring 26. An opening toothed plate 15 meshes with the side of the opening gear 25. The opening toothed plate 15 is slidably connected to the ATP fluorescence detector 1. The opening hook 12 pushes the opening toothed plate 15 upward, thereby driving the opening gear 25 to rotate, allowing the cover 2 to be opened.

[0023] The support component includes a support 7 elastically mounted on the lower part of the guide sleeve 10. A smart contact sensor 28 is installed through the end of the support 7. The support 7 serves to support the ATP swab 23. The smart contact sensor 28 can sense whether the ATP swab 23 is in place and send a control signal to control the operation of the first electric actuator 5 and the second electric actuator 16 through the controller. Since the above-mentioned control method through sensor sensing is existing technology and has been widely used, it is not described in detail here.

[0024] A shaft bracket 6 is fixedly installed on the lower part of one side of the guide sleeve 10. A connecting shaft 29 is rotatably installed through the lower end of the shaft bracket 6. The shaft bracket 6 serves to support the connecting shaft 29. The support 7 is fixed to the outer surface of the connecting shaft 29. The connecting shaft 29 serves to allow the support 7 to rotate. When the sampling cotton head 38 of the ATP swab 23 is wetted, the cap opening hook 12 on the control frame 8 just abuts against the cap opening tooth plate 15. Then the first electric push rod 5 continues to work. At this time, the cap opening hook 12 will push the cap opening tooth plate 15 to move it upward, thereby driving the cap opening gear 25 to rotate, allowing the cover 2 to open. The cover 2 can be flipped up and opened. When the cover 2 flips up and detaches from the bottom of the guide sleeve 10, the top wheel 4 on the top frame 3 just abuts against the lower end of the support 7. Then the first electric push rod 5 continues to work, allowing the top wheel 4 to push the support 7, causing the support 7 to rotate around the connecting shaft 29, allowing the support 7 to detach from the bottom of the guide sleeve 10. At this time, the ATP swab 23 will slide down without the support of the support 7 and enter the detection chamber at the top of the ATP fluorescence detector 1 under the guidance of the guide sleeve 10. The process does not require manual operation by the testing personnel, thereby improving the convenience of testing.

[0025] A first recess 30 is fixedly installed near the edge of the upper end of the support 7. A limit sleeve 31 is rotatably installed inside the first recess 30. A limit rod 32 is slidably installed inside the limit sleeve 31. The limit rod 32 extends through the upper end of the limit sleeve 31. The cooperation between the limit sleeve 31 and the limit rod 32 can position the support 7 to the reset position, so that the support 7 is reset to a horizontal state. A second recess 33 is rotatably installed at the upper end of the limit rod 32. The side of the second recess 33 is fixed to the guide sleeve 10. Both the first recess 30 and the second recess 33 serve as a connection. A support spring 27 is wound around the outer side of the limit rod 32 and the outer side of the limit sleeve 31. The two ends of the support spring 27 are fixed to the upper end of the limit rod 32 and the lower end of the limit sleeve 31, respectively. The support spring 27 can reset the support 7 after rotation.

[0026] During testing, first, the sealing sleeve 37 of the ATP swab 23 is removed. Then, the sampling cotton head 38 of the ATP swab 23 is attached to a clean sheet for wiping. Next, the sealing sleeve 37 of the ATP swab 23 is reinserted into the sampling cotton head 38. Then, the sampled ATP swab 23 is placed inside the guide sleeve 10. At this time, the rubber sealing cap 36 at the top of the ATP swab 23 is located on the outside of the guide sleeve 10. Simultaneously, the intelligent contact sensor 28 on the support 7 contacts the ATP swab 23 and sends a signal, which drives the second electric actuator 16 to work through the controller. The second electric actuator 16 moves the opening plate 17 to the side, thereby agitating and breaking the flow-blocking rod 35 on the ATP swab 23. Then, the first electric actuator 5 drives the control frame 8 to move, so that the guide wheel 22 rolls along the wave part inside the control frame 8, thereby driving the two plate frames 20 to move towards each other continuously, thereby driving the two squeezing plates 9 to move towards each other continuously. Repeatedly squeezing the rubber sealing cap 36 at the top of the ATP swab 23 allows the reagent to flow downwards, wetting the sampling cotton head 38 of the ATP swab 23. After wetting, the cap opening hook 12 on the control frame 8 just abuts against the cap opening toothed plate 15. Then, the first electric actuator 5 continues to work. At this time, the cap opening hook 12 will push the cap opening toothed plate 15 upwards, thereby driving the cap opening gear 25 to rotate, allowing the shell cover 2 to flip up and open. When the shell cover 2 flips up and disengages from under the guide sleeve 10... The top wheel 4 on the top frame 3 abuts against the lower end of the support 7. Then, the first electric actuator 5 continues to work, allowing the top wheel 4 to push the support 7, causing the support 7 to rotate around the connecting shaft 29. This allows the support 7 to detach from the bottom of the guide sleeve 10. At this time, the ATP swab 23 will slide down without the support of the support 7 and enter the detection chamber at the top of the ATP fluorescence detector 1 under the guidance of the guide sleeve 10 for detection, thereby determining whether the cleanliness of the bed sheet after washing is qualified.
