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.

[0025] Example 1: Please refer to Figure 1-4The utility model provides a technical solution: a purification instrument for detecting insecticides and pesticides, comprising an instrument body 1, a hollow block 2 is installed on the instrument body 1, a plurality of filter plates 3 are slidably installed on the hollow block 2, a cleaning structure is installed on the hollow block 2, the cleaning structure is in contact with the filter plate 3, a collection structure and a locking structure are installed on the hollow block 2, and the locking structure is in contact with the filter plate 3;

[0026] The cleaning structure includes two guide rods 4, both of which are mounted on the inner wall of the hollow block 2, and scrapers 41 are slidably mounted on the two guide rods 4, and a cleaning brush is mounted on the scraper 41, and the cleaning brush contacts the filter plate 3, and a threaded rod 42 is rotatably mounted on the hollow block 2, and the scraper 41 is threadedly mounted on the threaded rod 42, and a worm gear 43 is mounted on one end of the threaded rod 42, and a worm 44 is meshed on the worm gear 43, and two fixed blocks 45 are rotatably mounted on the worm 44, and the two fixed blocks 45 are mounted on the hollow block 2, and the worm 44 A fixing block 45 is installed on one end of the hollow block 2, and a forward and reverse servo motor 47 is installed on the driving shaft 46. The forward and reverse servo motor 47 is installed on the hollow block 2. After water is poured into the hollow block 2, the forward and reverse servo motor 47 is immediately driven, and the threaded rod 42 is driven by the forward and reverse servo motor 47 to rotate. The threaded rod 42 drives the scraper 41 to reciprocate on the filter plate 3, so that the large particles of impurities remaining on the filter plate 3 can be easily cleaned up to avoid clogging the filter holes on the filter plate 3, thereby reducing the filtering speed of the flowing water in the hollow block 2.

[0027] In order to collect the impurities removed from the filter plate 3 by the scraper 41, a collection structure is arranged on the hollow block 2, specifically including a mounting groove 5. A mounting groove 5 is provided on the inner wall of the bottom side of the hollow block 2. A collection drawer 51 is slidably installed on the mounting groove 5. The collection drawer 51 is adapted to the scraper 41. A handle 52 is provided on the collection drawer 51. A plug-in groove 55 is provided on the handle 52. A positioning block 53 is provided on the hollow block 2. A latch 54 is slidably installed on the positioning block 53. The bottom end of the latch 54 is movably installed in the plug-in groove 55. When filtering flowing water, insert the debris collection drawer 51 into the mounting groove 5 on the hollow block 2, and then insert the latch 54 on the positioning block 53 into the insertion groove 55 on the handle 52, so that the debris collection drawer 51 can be fixed on the hollow block 2 to collect the impurities scraped off the filter plate 3 by the scraper 41. After the water is filtered in the hollow block 2, it is only necessary to pull out the latch 54 on the positioning block 53 from the insertion groove 55 on the handle 52 to remove the debris collection drawer 51 from the hollow block 2, so that the collected impurities can be quickly and conveniently cleaned.

[0028] The working principle is as follows: when using the filter plate 3 on the hollow block 2 to filter the water poured into the hollow block 2, first fix the filter plate 3 on the hollow block 2 in sequence. When installing the filter plate 3, you only need to directly plug the filter plate 3 into the corresponding installation hole on the hollow block 2. When plugging, the filter plate 3 moves downward and contacts with the inclined surface of the locking block 63, and causes the locking block 63 to shrink into the locking cavity 61. The locking block 63 moves to the left to drive the moving push plate 62 to move. The movement of the moving push plate 62 drives the return spring 64 to move. Then, when the filter plate 3 continues to move downward to the lowest end, the limit groove 65 on the filter plate 3 and the lock are in contact. The stop block 63 overlaps, so that the movable push plate 62 is driven to move rightward under the action of the restoring force of the return spring 64, and the movable push plate 62 drives the locking block 63 to be quickly inserted into the limiting groove 65 on the filter plate 3, so that the filter plate 3 can be conveniently fixed. When the filter plate 3 needs to be taken out from the hollow block 2, it is only necessary to push the movable push plate 62 to the left to conveniently disengage the locking block 63 from the limiting groove 65 on the filter plate 3, so that the corresponding filter plate 3 can be taken out from the hollow block 2. After the filter plate 3 is fixed, water can be poured into the hollow block 2, and the filter plate 3 is used to filter the flowing water;

[0029] During the filtering process, the switch on the forward and reverse servo motor 47 is started, and the forward and reverse servo motor 47 is used to drive the driving shaft 46 to rotate, and the driving shaft 46 drives the worm 44 on the fixed block 45 to rotate, and the worm 44 drives the worm wheel 43 to rotate, and the worm wheel 43 drives the threaded rod 42 to rotate, and the threaded rod 42 drives the scraper 41 to move left and right on the filter plate 3, so that the large particles of impurities remaining on the filter plate 3 can be easily removed, and the filter holes on the filter plate 3 can be effectively avoided from being blocked, thereby reducing the filtering speed of the flowing water in the hollow block 2;

[0030] When the filter plate 3 filters the flowing water, the debris collection drawer 51 is inserted into the installation groove 5 on the hollow block 2, and then the pin 54 on the positioning block 53 is inserted into the insertion groove 55 on the handle 52, so that the debris collection drawer 51 can be fixed on the hollow block 2 to collect the impurities scraped off the filter plate 3 by the scraper 41. After the water is filtered in the hollow block 2, it is only necessary to pull out the pin 54 on the positioning block 53 from the insertion groove 55 on the handle 52 to remove the debris collection drawer 51 from the hollow block 2, so that the collected impurities can be quickly and conveniently cleaned.

[0031] Embodiment 2: On the basis of embodiment 1, in order to be able to fix and remove the filter plate 3 individually, a locking structure is arranged on the hollow block 2, specifically including a locking box 6, the locking box 6 is installed on the hollow block 2, a locking cavity 61 is provided on the locking box 6, a movable push plate 62 is slidably installed on the inner wall of the locking cavity 61, a locking block 63 is installed on one side of the movable push plate 62, a limiting groove 65 is provided on the filter plate 3, the locking block 63 is movably installed in the limiting groove 65, a return spring 64 is installed on the inner wall of the locking cavity 61, and the other end of the return spring 64 is installed on the movable push plate 62. When using the filter plate 3 on the hollow block 2 to filter the water poured into the hollow block 2, the filter plate 3 is first fixed on the hollow block 2 in sequence. When installing the filter plate 3, it only needs to directly plug the filter plate 3 into the corresponding mounting hole on the hollow block 2. When plugging in, The filter plate 3 moves downward and contacts the inclined surface of the locking block 63, causing the locking block 63 to shrink into the locking cavity 61. The locking block 63 moves leftward and drives the movable push plate 62 to move. The movable push plate 62 moves and drives the return spring 64 to move. Then, when the filter plate 3 continues to move downward to the lowest end, the limit groove 65 on the filter plate 3 coincides with the locking block 63, so that under the action of the restoring force of the return spring 64, the movable push plate 62 will be driven to move rightward, and the movable push plate 62 drives the locking block 63 to quickly insert into the limit groove 65 on the filter plate 3, so that the filter plate 3 can be fixed conveniently. When the filter plate 3 needs to be removed from the hollow block 2, it is only necessary to push the movable push plate 62 to the left, so that the locking block 63 can be easily disengaged from the limit groove 65 on the filter plate 3, so that the corresponding filter plate 3 can be removed from the hollow block 2. The remaining features are the same as those in Example 1.
