[0035] See also Figure 1-Figure 3 , Figure 5 As shown, this embodiment is a heavy metal residue detection device, comprising:

[0036] The main body component includes a detection slot 12 and a card slot 13 fixed at the top of the detection slot 12;

[0037] The detection slot 12 is used for detection, and the card slot 13 is used to place an instrument with a sample liquid;

[0038] A cleaning assembly, the cleaning assembly includes an elastic cord 21 fixed at the inner corner of the card slot 13, a placement plate 22 fixed between the bottom ends of the elastic cord 21, a brush 23 fixed to the outer periphery of the placement plate 22, and a connection pad 24 fixed to the bottom end of the placement plate 22;

[0039] The elastic cord 21 is used to connect the placement plate 22, and the placement plate 22 is used to place the bottom of the device. The brush 23 can clean the inner side wall of the card slot 13, and the connection pad 24 can clean the inner bottom surface of the card slot 13;

[0040] A limiting assembly, the limiting assembly includes a limiting plate 31 movably connected to both sides of the inside of the card slot 13;

[0041] The limiting plate 31 is used to limit the pop-up placement plate 22;

[0042] A vertical rod 25 is fixedly connected to the center of the bottom end of the slot 13, and a magnetic block 26 is fixedly connected to the bottom end of the vertical rod 25;

[0043] The vertical rod 25 is engaged with the vertical groove 27 at the bottom of the connection pad 24, and the magnetic block 26 can limit the connection pad 24;

[0044] A vertical groove 27 is provided in the center of the bottom surface of the connection pad 24, and the vertical groove 27 extends to the inside of the placement plate 22;

[0045] The bottom surface of the connection pad 24 is sticky;

[0046] The vertical groove 27 is connected with the placement plate 22 and the connection pad 24. At this time, the connection pad 24 can adhere to the debris on the bottom surface of the slot 13, thereby achieving a cleaning effect;

[0047] A magnetic area 28 is fixedly connected to the bottom edge of the vertical groove 27, and the magnetic area 28 is attracted to the magnetic block 26;

[0048] When the device is light, in order to prevent the elastic rope 21 and the placement plate 22 from moving the device, a magnetic block 26 is arranged to be attracted to the magnetic area 28, thereby limiting the placement plate 22 located on the bottom surface of the slot 13;

[0049] The main assembly also includes a display screen 14 fixed to one side of the detection slot 12, and a box body 11 fixed to the periphery of the detection slot 12 and the display screen 14;

[0050] The display screen 14 is used to display the detection process and results, and the box 11 is used to place the detection slot 12 and the display screen 14;

[0051] Working principle:

[0052] The instrument with the sample is placed in the card slot 13. At this time, the gravity of the instrument pushes the placement plate 22 downward, so that the placement plate 22 moves downward through the elastic rope 21. During the process of the placement plate 22 moving downward, the outer brush 23 cleans the inner side wall of the card slot 13.

[0053] When the placement plate 22 reaches the bottom surface of the slot 13, the vertical rod 25 is engaged with the vertical slot 27, the magnetic block 26 is attracted to the magnetic area 28, and the bottom surface of the connection pad 24 adheres to the debris on the bottom surface of the slot 13, thereby achieving the effect of cleaning the inside of the slot 13;

[0054] In the above steps, the interior of the card slot 13 can be cleaned through the interaction between the brush 23 and the connection pad 24 .

[0055] See also Figure 1-Figure 4 , Figure 6 As shown, this embodiment is based on the above embodiment 1 and also includes:

[0056] Limiting components;

[0057] The limiting assembly also includes a movable groove 32 opened at the connection between the limiting plate 31 and the card slot 13, and a limiting rod 33 penetrating the connection between the limiting plate 31 and the movable groove 32;

[0058] The movable groove 32 is used for the movement of the top end of the limiting plate 31, and the limiting rod 33 is used for the placement of the top end of the limiting plate 31;

[0059] Both ends of the limiting rod 33 extend into the movable groove 32, and the two are fixedly connected;

[0060] Both sides of the limit rod 33 are fixedly connected to the inside of the movable groove 32, so as to facilitate the movement of the outer end of the limit rod 33;

[0061] A spring 34 is fixedly connected to the inner side of the bottom end of the limiting plate 31, and the other end of the spring 34 is fixedly connected to the inside of the slot 13;

[0062] When the placement plate 22 moves upward, it will squeeze the bottom end of the limit plate 31. At this time, the bottom end of the limit plate 31 moves inward through the spring 34, so that the upper part of the limit plate 31 limits the placement plate 22.

[0063] Working principle:

[0064] After the inspection is completed, the device is taken out by hand. After taking it out, the elastic rope 21 drives the placement plate 22 to move up, and the vertical rod 25 leaves the vertical groove 27. When the placement plate 22 moves up to the bottom end of the limiting plate 31, the brush 23 on the outside of the placement plate 22 squeezes the bottom end of the limiting plate 31. At this time, the bottom end of the limiting plate 31 presses the spring 34 inward, and the top end of the limiting plate 31 rotates, so that the center of the outer end of the limiting plate 31 limits the brush 23 and the placement plate 22 to prevent the placement plate 22 from being excessively ejected;

[0065] The above steps can improve the functionality of self-injury.
