Detailed Description
In order to make the technical solutions of the present invention better understood, the following description of the technical solutions of the present invention with reference to the accompanying drawings of the present invention is made clearly and completely, and other similar embodiments obtained by a person of ordinary skill in the art without any creative effort based on the embodiments in the present application shall fall within the protection scope of the present application. In addition, directional terms such as "upper", "lower", "left", "right", etc. in the following embodiments are directions with reference to the drawings only, and thus, the directional terms are used for illustrating the present invention and not for limiting the present invention.
As shown in fig. 1-3, an auxiliary device for detecting food additives comprises a sample feeding plate 200 for accommodating a headspace bottle 100 and a sample cover 400 for closing the mouth of the headspace bottle 100, wherein a sample groove 210 for accommodating the headspace bottle 100 is arranged on the sample feeding plate 200, a limiting plate 300 for limiting the sample cover 400 is further arranged between the sample feeding plate 200 and the sample cover 400, the limiting plate 300 is limited on the upper surface of the sample feeding plate 200 through the headspace bottle 100, the sample cover 400 is buckled on the upper surface of the limiting plate 300, and a limiting block 320 for limiting the buckling position of the sample cover 400 is arranged on the side wall of the limiting plate 300. The structures of the limiting plate 300 and the sample plate cover 400 are added on the basis of the original sample plate 200, so that the phenomenon of spilling and leaking in the sample transfer process is avoided; a plurality of bottle mouths of the headspace bottles 100 placed in the sample inlet plate 200 are buckled in batch at one time through the sample plate cover 400, so that the convenience and the rapidness are realized, the covering efficiency is improved, and the experiment efficiency is further improved; the covering position of the sample plate cover 400 is limited through the limiting plate 300, the covering degree is ensured to be proper, and meanwhile the service life of the sample plate cover 400 is prolonged.
Further, a position corresponding to the sample groove 210 on the position-limiting plate 300 is provided with a position-limiting hole 310 matched with the sample groove 210, and the aperture of the sample groove 210 is the same as that of the position-limiting hole 310. The limiting plate 300 is completely arranged corresponding to the sample inlet plate 200, and the limiting hole 310 and the sample groove 210 are arranged in the same size and position, and the difference is that the limiting hole 310 is a through hole, and the sample groove 210 is a cylindrical groove with a closed bottom end. Because the inlet sample plate 200 is a standard component, the height of the inlet sample plate is usually set to be one third to two thirds of the body of the headspace bottle 100, the position of the opening of the headspace bottle 100 with different body lengths can be effectively positioned by additionally arranging the limiting plate 300, and the influence on the sealing degree of the sample plate cover 400 when batches of headspace bottles 100 with different body heights are used is avoided.
Further, the template cover 400 comprises a film 410 for covering the mouth of the headspace bottle 100 and a fixing frame 420 arranged around the film 410 for fixing the film 410, wherein the film 410 is detachably and fixedly connected with the fixing frame 420. The size of the fixing frame 420 is slightly larger than the external size of the limiting plate 300, so that the fixing frame 420 can slide and cover on the outer wall of the limiting plate 300; the film 410 of detachable installation makes film 410 can change when reaching life, reduces the material expense of changing whole sample plate lid 400, and film 410 adopts flexible material, avoids film 410 mounted position when improper autoinjection needle is difficult to pierce through the sample.
Further, a sampling hole 411 is formed in the film 410 corresponding to each sample chamber 210, and the sampling hole 411 is coaxially disposed with the sample chamber 210. Set up the thief hole 411 and can effectively reduce the irregular puncture damage of autoinjection to film 410, be favorable to prolonging film 410's cyclic service life, thief hole 411 edge is provided with the reinforcement edge, further strengthens thief hole 411's structural strength, avoids film 410 to drag when covering the bottleneck and leads to thief hole 411 edge fracture impaired.
Further, the aperture of the sampling hole 411 is smaller than that of the sample tank 210. The aperture of the sampling hole 411 is slightly larger than the outer diameter of the syringe of the automatic sampling needle and much smaller than the aperture of the sample groove 210, so that the membrane 410 is only provided with a small-sized hole at the center of the bottle mouth to be communicated with the outside after covering the bottle mouth, thereby preventing the liquid in the headspace bottle 100 from flowing out along the sampling hole 411.
Further, the height from the film 410 to the bottom end of the fixing frame 420 is not greater than the height from the upper surface of the limiting plate 300 to the limiting block 320. The difference in height between film 410 and stopper 320 will set up suitably to the realization is to the better sealed of bottleneck, avoids setting up too big unable contact bottleneck because of the difference in height, and sets up the undersize and leads to unable contact limiting plate 300 of mount 420 because of the difference in height.
Further, the film 410 is formed by a silicone mold. The silica gel mould can be used repeatedly through washing stoving process, and possesses the pliability of sealed bottleneck and the stability that does not take place chemical reaction with the sample. The film 410 can also be replaced by disposable tin foil paper, so that the experiment cost is reduced.
Further, the limiting block 320 is fixed around the limiting plate 300. All set up stopper 320 all around and can avoid the sample plate lid 400 to close the in-process because of the slope leads to the lid degree inconsistent, and the condition that does not close even takes place.
Further, the limiting block 320 is an L-shaped right-angle block. L shape right angle piece sets up on four angles of limiting plate 300, is equivalent to set up two stopper 320 in each side, has set up eight stopper 320 altogether, improves the stability of lock.
Further, the sum of the height of the limiting hole 310 and the height of the sample groove 210 is less than the height of the headspace bottle 100. The height of the sample inlet plate 200 is generally fixed and unchanged, the headspace bottles 100 have different specification sizes, the heights of the headspace bottles 100 with different volume capacities are different, and the proper covering degree of the sample plate cover 400 is ensured by arranging the limiting plate 300, so that the height of the limiting plate 300 (namely, the height of the limiting hole 310) is required to enable the headspace bottle 100 to be just exposed out of the bottle mouth after being placed in, and the exposed bottle mouth is conveniently sealed along the film.
The present invention has been described in detail, and it should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the utility model, are intended for purposes of illustration only and are not intended to limit the scope of the utility model.
