DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 12 One embodiment of the present invention is: a xylitol purity detection device, including a body 11, and also including a feeding device; wherein the bottom wall of the body 11 is fixedly connected with a bottom block 12, the top of the bottom block 12 is fixedly connected with a boss 13, the top of the boss 13 is fixedly connected with a spring 15, the top of the spring 15 is fixedly connected with a bottom plate 16, and the top of the bottom plate 16 is fixedly connected with a reaction barrel 14; wherein the feeding device includes: a vertical plate 21, a top plate 22, a support plate 26, a feed box 27, a pressing plate 28, a connecting pipe 29, a discharge port 210 and a bottom cover 211, the vertical plate 21 is fixedly connected to the top of the boss 13, the top plate 22 is fixedly connected to the top of the vertical plate 21, the top plate 22 is provided with round holes on the upper and lower sides, and the support plate 2 6 is placed on the top of the top plate 22, the feed box 27 is fixedly passed through the support plate 26, the feed box 27 slides through the round hole, one end of the connecting tube 29 is fixedly connected to the bottom of the reaction barrel 14, the pressing plate 28 is fixedly connected to the other end of the connecting tube 29, the discharge port 210 is fixedly connected to the bottom of the feed box 27, and the bottom cover 211 is rotatably connected to the bottom of the discharge port 210. The gravity of the water will move the bottom plate 16 downward. When the bottom plate 16 is pressed downward, the pressing plate 28 will press the xylitol powder in the feed box 27 downward, and the xylitol powder will fall into the reaction barrel 14, which can effectively prevent the xylitol powder from being added too much and not being completely dissolved. The device can control the amount of xylitol powder added by the amount of water.

[0021] The feeding device also includes: a water tank 23, a water pump 24 and a water outlet 25. The water tank 23 is fixedly connected to the rear side of the body 11, the water pump 24 is fixedly connected to the front side of the water tank 23, and the water outlet 25 is fixedly connected to the water outlet end of the water pump 24. The amount of water entering can be controlled by switching the water pump 24.

[0022] The pressing plate 28 is slidably connected to the inside of the feed box 27 , and a torsion spring is provided between the bottom cover 211 and the discharge port 210 , and the torsion spring can help the bottom cover 211 to return to its original position.

[0023] When the present embodiment is working, by starting the water pump 24, the water pump 24 will pump out the water in the water tank 23. When the water pump 24 pumps out the water in the water tank 23, the water in the water tank 23 will pass through the water pump 24. When the water passes through the water pump 24, the water will pass through the water outlet 25 and flow out from the water outlet 25. When the water flows out from the water outlet 25, the water will flow into the reaction barrel 14. When the water flows into the reaction barrel 14, the gravity of the water will cause the reaction barrel 14 to press the bottom plate 16 downward.

When the bottom plate 16 moves downward, the bottom plate 16 will drive the connecting pipe 29 to move downward. When the connecting pipe 29 moves downward, the connecting pipe 29 will drive the pressing plate 28 to move downward. When the pressing plate 28 moves downward, the pressing plate 28 will move to The xylitol powder in the feed box 27 is pressed downward. When the pressing plate 28 presses the xylitol powder downward, the xylitol powder will pass through the discharge port 210. When the xylitol powder passes through the discharge port 210, the xylitol powder will squeeze the bottom cover 211 downward. When the xylitol powder squeezes the bottom cover 211 downward, the bottom cover 211 will be pushed open by the xylitol powder. When the bottom cover 211 is pushed open by the xylitol powder, the xylitol powder will fall into the reaction barrel 14. When the xylitol powder falls into the reaction barrel 14, the xylitol powder will dissolve in the water in the reaction barrel 14. When the water pump 24 stops working, the connecting pipe 29 will not move downward any more. When the connecting pipe 29 no longer moves downward, the bottom cover 211 will return to its original position under the action of the torsion spring to prevent the xylitol powder from falling out, which can effectively prevent the xylitol powder from being added too much and not being completely dissolved.

[0029] When the present embodiment is working, when water enters the reaction barrel 14, the water will contact the water receiving barrel 32. When the water contacts the water receiving barrel 32, the water will be poured into the water receiving barrel 32. When the water is poured into the water receiving barrel 32, the water receiving barrel 32 will move downward as the weight increases. When the water receiving barrel 32 moves downward as the weight increases, the water receiving barrel 32 will drive the connecting plate 33 to move downward. When the water receiving barrel 32 drives the connecting plate 33 to move downward, the connecting plate 33 will drive the pentagonal block 34 to rotate. When the pentagonal block 34 rotates, the pentagonal block 34 will cause the connecting plate 33 and the water receiving barrel 32 to rotate. When the pentagonal block 34 rotates, the pentagonal block 3 4 will drive the support rod 31 to rotate. When the connecting plate 33 and the water receiving bucket 32 ​​rotate, the connecting plate 33 and the water receiving bucket 32 ​​will stir the water and xylitol powder in the reaction barrel 14. When the connecting plate 33 and the water receiving bucket 32 ​​rotate, the water receiving bucket 32 ​​will contact with the rotating plate 1 37. When the water receiving bucket 32 ​​contacts with the rotating plate 1 37, the rotating plate 1 37 will be pushed by the water receiving bucket 32.

When the rotating plate 1 37 rotates, the rotating plate 1 37 will stir the water and xylitol powder in the reaction barrel 14, which can help the water receiving bucket 32 ​​to stir so that the xylitol powder is fully dissolved.

[0030] When the xylitol powder contains impurities or incompletely dissolved xylitol powder, the impurities and incompletely dissolved xylitol powder will stay on the top of the filter plate 412. When the support rod 1 31 rotates, the support rod 1 31 will drive the rotating plate 2 41 to rotate. When the rotating plate 2 41 rotates, the rotating plate 2 41 will rotate and contact with the rotating plate 3 42. When the rotating plate 2 41 contacts the rotating plate 3 42, the rotating plate 2 41 will push the rotating plate 3 42. When the rotating plate 2 41 pushes the rotating plate 3 42, the rotating plate 3 42 will rotate. When the rotating plate 42 rotates, the rotating plate 3 42 will contact the rotating plate 43. When the rotating plate 3 42 contacts the rotating plate 43, the rotating plate 43 will drive the rotating frame 44 to rotate.

When the baffle 47 rotates, the baffle 47 contacts the rubber column 48. When the baffle 47 contacts the rubber column 48, the rubber column 48 drives the baffle 47 to slide. When the rubber column 48 drives the baffle 47 to slide, the long grooves on the inner and outer walls of the rotating frame 44 leak out. When the long grooves on the inner and outer walls of the rotating frame 44 leak out, impurities and incompletely dissolved Xylitol powder will flow into the impurity bin 49 through the long groove. When the rotating frame 44 continues to rotate, the rubber column 48 will be pushed and deformed by the baffle 47. When the rubber column 48 is deformed, the rubber column 48 cannot block the baffle 47. The baffle 47 will be reset under the elastic force of the No. 1 spring to prevent excess water from flowing out. When the reaction of xylitol powder and water is completed, the water receiving pipe 410 can be opened. When the water receiving pipe 410 is opened, the xylitol liquid that has completed the reaction will flow into the receiving barrel 411 for the next step of detection.
