Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 The utility model provides a technical solution: a methoxybenzaldehyde compound detector that is easy to clean, comprising a shell 1, a sealing cover 2 is threadedly connected to the inner wall of the shell 1, a water stain erasing mechanism 3 is arranged on the inner wall of the sealing cover 2, a reaction tank 4 is fixedly connected to the inner wall of the shell 1, and a replacement mechanism 5 is arranged on the inner wall of the reaction tank 4;

[0022] The water stain erasing mechanism 3 includes a partition plate 31 and a motor 33. The side walls of the partition plate 31 are fixedly connected to the inner wall of the sealing cover 2. A threaded groove 32 is provided at the middle position of the partition plate 31. The outer wall of the motor 33 is fixedly connected to the inner wall of the sealing cover 2. The output shaft of the motor 33 is fixedly connected with a connecting shell 34. A guiding groove 35 is provided on the inner wall of the connecting shell 34. A threaded rod is arranged inside the connecting shell 34. A guiding block 36 is fixedly connected to the outer wall of one side of the threaded rod. The threaded rod is slidably connected to the inner wall of the connecting shell 34 through the guiding block 36 and the guiding groove 35. The threaded rod is in threaded connection with the threaded groove 32. The bottom end of the threaded rod extends below the partition plate 31 and is fixedly connected with a mounting shell 37. The bottom end of the mounting shell 37 is fixedly connected with an erasing plate 38;

[0023] Furthermore, the replacement mechanism 5 includes a spring 51 and a locking rod 55. The spring 51 is fixedly connected to the inner wall of the mounting shell 37. The spring 51 is arranged in central symmetry. And the bottom ends of both springs 51 are fixedly connected with a rotating rod 52. The side wall of the rotating rod 52 is rotatably connected to the inner wall of the mounting shell 37. The bottom wall of the rotating rod 52 is fixedly connected with a first slider 53. A second slider 54 is arranged below the first slider 53. The bottom wall of the locking rod 55 is fixedly connected to the upper wall of the erasing plate 38. A locking groove 56 is provided on the side wall of one end of the locking rod 55 close to the rotating rod 52. The replacement mechanism 5 avoids the problem of the decline in the erasing effect caused by the saturation of the sponge after the erasing plate 38 is used multiple times;

[0024] Furthermore, a funnel is fixedly connected to the outer wall of the housing 1. And the side wall of the funnel penetrates through the outer wall of the housing 1 and the outer wall of the reaction tank 4 and extends into the reaction tank 4. A solenoid valve is fixedly connected to the bottom wall of the reaction tank 4. A drain hole is provided at the position below the solenoid valve on the bottom wall of the housing 1. The inner wall of the reaction tank 4 is cylindrical. The operator pours the methoxybenzaldehyde compound to be detected and the detection solvent into the reaction tank 4 through the funnel. Then wait for the reaction to complete. Control the solenoid valve to open. And drain the mixed methoxybenzaldehyde compound solution into the detector through the drain hole for detection;

[0025] Furthermore, the length of the connecting shell 34 is equal to the length of the threaded rod. The length of the threaded rod is equal to the depth of the reaction tank 4. The erasing plate 38 is U-shaped. Sponges are fixedly connected to the bottom wall and the side wall of the erasing plate 38. The height of the erasing plate 38 is equal to the distance from the bottom wall of the partition plate 31 to the bottom wall of the sealing cover 2. When the motor 33 rotates in reverse, the threaded rod moves upward, and the threaded rod will drive the erasing plate 38 back into the sealing cover 2;

[0026] Furthermore, the spring 51 is in a compressed state in the initial state. Two limiting rods are fixedly connected to the inner wall of the mounting shell 37. And the two limiting rods are arranged in central symmetry. And the two limiting rods are on the same horizontal plane. The rotating rod 52 moves towards the center under the reset action of the spring 51 and is limited by the limiting rods to return to the locking groove 56;

[0027] Furthermore, the bottom wall of slider No. 1 53 has a machine-formed inclined surface, and the side wall of slider No. 2 54 has a machine-formed inclined surface, and the inclined surface of the bottom wall of slider No. 1 53 presses against the inclined surface of the side wall of slider No. 2 54. Slider No. 1 53 and slider No. 2 54 are both slidably connected to the inner wall of the mounting shell 37 through a slide groove, and the sliding direction of slider No. 1 53 is vertical, and the sliding direction of slider No. 2 54 is horizontal. Slider No. 1 53 is pressed to move upward to lift the two rotating rods 52, and the two rotating rods 52 move obliquely upward to both sides and leave the locking groove 56 opened on the side wall of the locking rod 55.

[0028] Working principle: When using the easy-to-clean methoxybenzaldehyde compound detector, the operator pours the methoxybenzaldehyde compound to be detected and the detection solvent into the reaction tank 4 through the funnel, and then waits for the reaction to be completed, controls the solenoid valve to open, and discharges the mixed methoxybenzaldehyde compound solution into the detector through the drainage hole for detection;

[0029] Then, the operator pours the cleaning liquid into the reaction tank 4 through the funnel and then discharges it through the drainage hole. At this time, the operator starts the water stain wiping mechanism, and the motor 33 drives the connecting shell 34 fixedly connected to the output end to rotate. The threaded rod slidably connected in the connecting shell 34 is driven to rotate. At the same time, the threaded rod is threadedly connected to the threaded hole opened on the upper wall of the blocking plate 31, and the threaded rod rotates and moves downward under the guidance of the threaded hole. The threaded rod rotates and moves downward, and the mounting shell 37 fixedly connected to the bottom end of the threaded rod also moves downward, so that the erasing plate 38 rotates and moves downward in the reaction tank 4. The sponge fixedly connected to the erasing plate 38 will wipe the water stains on the inner wall of the reaction tank 4. When the erasing plate 38 hits the bottom wall of the reaction tank 4, the motor 33 reverses and the threaded rod moves upward. Because the height of the erasing plate 38 is equal to the distance from the bottom wall of the blocking plate 31 to the bottom wall of the sealing cover 2, the threaded rod will drive the erasing plate 38 back into the sealing cover 2.

[0030] After a period of time, the sponge on the erasing plate 38 is saturated, and the operator rotates to remove the sealing cover 2 and starts the motor 33 to make the erasing plate 38 leave the sealing cover 2. The operator presses the second slider 54 on the mounting shell 37. Because the inclined surface of the bottom wall of the first slider 53 is pressed against the inclined surface of the side wall of the second slider 54, and the first slider 53 and the second slider 54 are both slidably connected to the inner wall of the mounting shell 37 through the sliding groove, the sliding direction of the first slider 53 is vertical, and the sliding direction of the second slider 54 is horizontal. Therefore, the No. 1 slider 53 will be pressed to move upward to lift the two rotating rods 52, and the two rotating rods 52 will move obliquely upward to both sides and leave the locking groove 56 opened on the side wall of the locking rod 55. The operator removes the erasing plate 38 and puts the new erasing plate 38 into the mounting shell 37. Because the spring 51 is initially in a compressed state and there are two limit rods fixedly connected to the inner wall of the mounting shell 37, the rotating rod 52 is reset by the spring 51 to move closer to the center and is limited by the limit rod to return to the locking groove 56.

[0031] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Simple modifications or equivalent substitutions of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
