The utility model uses the slide groove, the cross bar, the slider, the cleaning component and the limit component to press the two pressing plates in the opposite directions, drive the control rod and the control column to move, and the control column drives the connecting plate and the limit stop rod to move backward through the control bar, thereby solving the problem that the detection area of ​​the existing detection instrument may have dust and other debris residues after long-term use, which affects the detection effect of the detection instrument and is not convenient for long-term use of the instrument.

[0004] However, the dust and stains in the detection slot inside the detector are difficult to clean. The stains inside interfere with the optical measurement of the sample liquid in the test tube inserted inside, affecting the accuracy of the test results. In addition, there are five planes distributed in the detection slot. It is usually difficult for manual cleaning to reach the bottom surface of the lowest position of the detection slot, and a large area is missed when cleaning. Utility Model Content

[0011] Preferably, the height of the axis of the cleaning cylinder in the rotation reset state is lower than the height of the lower surface of the cleaning frame.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model is provided with a lifting cleaning frame, which rotates the protective cover to cover the top of the detection groove, and operates the driving motor to control the rotation of the driving rod. One end of the driving rod is embedded in the bar sliding frame to slide and move. Under the pushing action of the sliding structure, the lifting component can be controlled to slide back and forth up and down through the protective cover.

[0027] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] See also Figure 1-Figure 7 As shown, a self-cleaning food pesticide residue detector includes a detector body 1, a detection slot 11 opened on the detector body 1 for placing pipe fittings, and a protective cover 12 for protecting the detection slot 11. The food pesticide residue detector also includes a cleaning frame 2 for cleaning the inside of the detection slot 11, and a lifting assembly 3 for controlling the cleaning frame 2 to reciprocate along the depth direction of the detection slot 11. The outer wall of the cleaning frame 2 is in contact with the inner wall of the detection slot 11. A plurality of detection slots 11 are opened in the detector body 1. The number and position of the cleaning frame 2 correspond to the number and position of the detection slots 11. The cleaning frame 2 can be made of a variety of cleaning flexible materials and is in contact and friction with the inner wall of the detection slot 11.

[0029] When using the detector body 1, the protective cover 12 is rotated to open, the detection slot 11 is exposed, the sample liquid to be tested is introduced into the corresponding square test tube, and the test tube is inserted into the detection slot 11. Through the color reaction of the sample liquid, the sample liquid is quickly detected under optical action to analyze and judge the pesticide residue content in the food. As the use time increases, the detection slot 11 is gradually covered with some dust and stains. By driving the lifting component 3, the cleaning frame 2 can be controlled to move up and down. During the up and down reciprocating movement of the cleaning frame 2, its outer wall contacts the inner wall of the detection slot 11 to achieve the cleaning of the inner wall of the detection slot 11.

[0030] A sliding hole 31 is opened in the protective cover 12, and the lifting component 3 slides through the sliding hole 31. Two groups of driving rods 33 are symmetrically arranged in the front and back of the protective cover 12. The front driving rod 33 is interconnected with the output end of the driving motor 32, and the rear driving rod 33 rotates on the inner side of the protective cover 12. The two groups of rotating drive structures can maintain the stability of the up and down movement of the lifting component 3.

[0031] The protective cover 12 is rotated to cover the surface of the detector body 1. At this time, the cleaning frame 2 is correspondingly set at the position directly above the detection slot 11. During the reciprocating up and down movement of the cleaning frame 2 through the lifting assembly 3, its outer wall and the inner wall of the detection slot 11 are in contact with each other, and the inner wall of the detection slot 11 is automatically cleaned under the action of friction.

[0032] A driving motor 32 is installed on the protective cover 12 , and a driving rod 33 is connected to the output end of the driving motor 32 . A strip sliding frame 34 is slidably mounted on the driving rod 33 , and the strip sliding frame 34 is fixedly assembled with the lifting assembly 3 .

[0033] The driving motor 32 is operated to control the driving rod 33 to rotate. One end of the driving rod 33 is embedded in the strip sliding frame 34 to slide. Through the sliding transmission structure of the driving rod 33 and the strip sliding frame 34, the lifting component 3 can be reciprocated up and down. The lifting component 3 passes through the sliding hole 31 in the protective cover 12 and slides up and down. The lifting component 3 moves up and down to drive the cleaning frame 2 installed below to move synchronously. In this reciprocating state, the cleaning frame 2 contacts the inner wall of the detection groove 11 multiple times, thereby cleaning the inner wall of the detection groove 11.

[0034] A mounting boss 21 is fixed on the lifting assembly 3, and the cleaning frame 2 and the mounting boss 21 are snap-fitted together. The exterior of the mounting boss 21 is a step-like structure, and the cleaning frame 2 and the mounting boss 21 are detachably mounted so that the cleaning frame 2 and the mounting boss 21 can be disassembled and separated later.

[0035] During the cleaning process of the cleaning frame 2 in contact and friction with the inner wall of the detection groove 11, the stains in the detection groove 11 are transferred to the cleaning frame 2. As the use time increases, there are more stains on the surface of the cleaning frame 2 and it is difficult to play a cleaning role. The cleaning frame 2 is disassembled from the outside of the mounting boss 21, and the cleaning frame 2 is cleaned and dried. The cleaned cleaning frame 2 is then snap-fitted and installed to the outside of the mounting boss 21 to maintain its subsequent cleaning effect.

[0036] A reset shaft 22 is rotatably connected in the mounting boss 21, a rotating rod 23 is fixedly mounted on the reset shaft 22, a cleaning cylinder 24 is mounted on the rotating rod 23, two groups of cleaning cylinders 24 are arranged in the mounting boss 21, and the two groups of cleaning cylinders 24 are arranged in parallel in the middle position of the mounting boss 21, the reset shaft 22 is composed of a common shaft and a torsion spring combination, the common shaft is rotatably mounted on the inner side of the mounting boss 21, and the outside of the common shaft is connected to the inner side of the mounting boss 21 through a sleeved torsion spring, so that the common spring stretches the torsion spring during rotation, and the elastic force of the torsion spring rotation stretching can also push the common spring to rotate and reset.

[0037] In the process of the cleaning frame 2 moving downward and contacting the inner wall of the detection groove 11, the cleaning cylinder 24 first moves downward into the detection groove 11, and the cleaning cylinder 24 moves downward and contacts the bottom surface of the detection groove 11. The cleaning frame 2 continues to move downward, so that the cleaning cylinder 24 and the detection groove 11 contact each other to generate a reverse force. Under the action of the reverse thrust, the rotating rod 23 can be connected to the inner side of the mounting boss 21 through the reset shaft 22 to rotate. The rotating rod 23 rotates to push the cleaning cylinder 24 to fit the bottom surface of the detection groove 11 and move horizontally. The two groups of cleaning cylinders 24 move horizontally and contact the bottom of the detection groove 11. Contact friction realizes the cleaning effect on the bottom surface of the detection groove 11. When the cleaning frame 2 moves downward to the lowest position, the rotating rod 23 rotates and expands to the maximum position. The two sets of rotating rods 23 push the cleaning cylinder 24 to move horizontally to the side of the bottom surface of the detection groove 11. The cleaning range is larger. When the cleaning frame 2 moves upward, the contact thrust between the cleaning cylinder 24 and the detection groove 11 is reduced. Under the transmission action of the reset shaft 22, the two sets of cleaning cylinders 24 move to the middle position. Finally, the two sets of cleaning cylinders 24 are no longer in contact with the detection groove 11, and the two sets of cleaning cylinders 24 rotate and reset to the vertical initial state.

[0038] The height of the axis of the cleaning cylinder 24 in the rotation reset state is lower than the height of the lower surface of the cleaning frame 2.

[0039] When the cleaning frame 2 moves downward, the cleaning cylinder 24 first contacts the bottom surface of the detection slot 11. When the cleaning frame 2 moves down to the lowest position in the detection slot 11, the cleaning cylinder 24 moves laterally to the side of the detection slot 11. During the downward movement of the cleaning frame 2, the cleaning cylinder 24 is given a certain transmission range so that the bottom surface of the detection slot 11 can be cleaned more comprehensively.

[0040] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
