DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figures 1-4 As shown, a portable food detection pen includes a detection pen body 1, a pen tip 2 provided at the end of the detection pen body 1, and a detection head 3 provided on the pen tip 2. The pen tip 2 is connected to a protective structure 4, and the detection head 3 is located inside the protective structure 4. The end of the detection pen body 1 is provided with an anti-drop structure 5. A display screen 6 is fixed to the detection pen body 1, and a button 7 is provided on the detection pen body 1 near the display screen 6. The pen tip 2 is provided with an annular groove 8, and the protective structure 4 is connected to the pen tip 2 through the annular groove 8.

[0020] When using a portable food testing pen to test food, the user holds the testing pen body 1, connects the fingers to the anti-drop structure 5, removes the protective structure 4 from the pen tip 2 and connects it to the anti-drop structure 5, starts the testing pen by pressing the button 7, and the display screen 6 on the testing pen body 1 lights up, and then starts the testing work. During the testing process, the testing head 3 on the pen tip 2 is brought into contact with the food, and the harmful substances in the food are detected using the built-in electrodes, chemical reagents, etc. The test results are displayed in the form of data on the display screen 6, and it can be understood whether the current food is qualified based on the displayed data. During the testing process, since the anti-drop structure 5 is connected to the user's fingers, it can play an anti-drop role, avoiding damage to the testing head 3 caused by the testing pen falling, thereby increasing the service life of the entire testing pen. After the test is completed, the testing head 3 is cleaned and disinfected, and the protective structure 4 on the anti-drop structure 5 is removed, and the protective structure 4 is connected to the pen tip 2 through the annular slot 8 to protect the testing head 3.

[0021] Through the above implementation scheme, the protective structure 4 includes a protective cover 401, a snap-on protrusion 402, an anti-slip stripe 403, a snap-on clip 404 and a limit block 405. The snap-on protrusion 402 is arranged inside the protective cover 401, and the snap-on protrusion 402 is snapped into the annular groove 8 on the pen tip 2. The anti-slip stripe 403 is fixed to the outer surface of the protective cover 401, the snap-on clip 404 is fixedly connected to the limit block 405, and the snap-on clip 404 is connected to the protective cover 401.

[0022] When using the detection pen, the anti-slip stripes 403 exert force on the protective cover 401, causing it to be removed from the pen tip 2. The protective cover 401 is then connected to the anti-drop structure 5 using the snap clip 404 and the stop block 405, and the detection pen can then be used. After use, the protective cover 401 is removed from the anti-drop structure 5 and connected to the pen tip 2 using the snap protrusion 402 and the annular slot 8, thereby protecting the detection head 3.

[0023] By the above implementation, the anti-falling structure 5 includes a rotating plate 501, a connecting column 502, a through hole 503, a connecting band 504, a pressing screw 505, a knob 506 and an elastic connecting ring 507, the rotating plate 501 is fixedly connected with the connecting column 502, and the rotating plate 501 is rotatably installed on the detection pen main body 1, the through hole 503 is arranged on the connecting column 502, and the connecting column 502 is provided with a screw hole. The connecting band 504 is fixedly connected with the elastic connecting ring 507, and the connecting band 504 penetrates through the through hole 503 on the connecting column 502, the end of the connecting band 504 is connected with the rotating plate 501, the pressing screw 505 is fixedly connected with the knob 506, and the pressing screw 505 is connected in the screw hole, and the end of the pressing screw 505 abuts against the connecting band 504.

[0024] After holding the detection pen main body 1, the elastic connecting ring 507 at the end of the connecting band 504 is sleeved on the finger of the user, and the protective structure 4 is connected to the connecting band 504 after being removed, in the use process, the rotating plate 501 can rotate on the detection pen main body 1, ensuring the flexibility of use, when the detection pen main body 1 falls from the hand, the connecting band 504 and the elastic connecting ring 507 play an anti-falling effect, avoiding the detection pen main body 1 from falling to the ground or the desktop, preventing damage caused by collision, and after use, the elastic connecting ring 507 is taken off from the finger, and the detection pen can be stored. In the process of using the detection pen, the relative length of the connecting band 504 can also be adjusted according to the actual situation, when adjusting, the pressing screw 505 is rotated by rotating the knob 506, the pressing screw 505 rotates and moves in the screw hole, when the end of the pressing screw 505 no longer contacts the connecting band 504, the connecting band 504 moves in the through hole 503 on the connecting column 502, so as to adjust the relative position of the connecting band 504, and after adjustment, the pressing screw 505 is rotated by the knob 506, and the connecting band 504 is fixedly pressed, so as to be used.

[0025] It should be noted that by setting the protective structure 4 and the anti-falling structure 5, the protective structure 4 can effectively protect the detection head 3, when using the detection pen, the protective cover 401 is connected to the anti-falling structure 5 through the clamping clamp 404 and the limiting block 405, without the need for special storage, avoiding the loss of the protective structure 4, the elastic connecting ring 507 is arranged at the end of the connecting band 504 in the anti-falling structure 5, the elastic connecting ring 507 can be sleeved on the finger, and the anti-falling effect is achieved in the process of using the detection pen, preventing the detection pen from falling and being damaged, the connecting band 504 penetrates through the through hole 503 on the connecting column 502, and is used in cooperation with the pressing screw 505 on the knob 506, the connecting band 504 can be moved after the pressing screw 505 is loosened, the length of the connecting band 504 relative to the connecting column 502 is adjusted, and the flexibility and adaptability of use are improved.
