[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figure 1-6 An embodiment of this utility model provides a food surface harmful substance sampling device, comprising: a box body 1, a top cover 102 installed on the top of the box body 1, an inlet and outlet 103 opened on the upper surface of the top cover 102, a rotating platform 2 installed inside the box body 1, a plurality of storage slots 201 arranged in a ring on the outer wall of the rotating platform 2, a sampling storage container 4 arranged inside the storage slots 201, a base 104 installed at the bottom of the box body 1, a shaft 205 installed in the groove in the middle of the base 104, and the upper end of the shaft 205 connected to the rotating platform 2, and a handle 204 installed at the lower end of the shaft 205;

[0026] The multiple storage slots 201 on the rotating platform 2 allow users to easily place multiple sampling and storage containers 4. These containers are used to store harmful samples from the surface of food. The handle 204 allows users to easily rotate the rotating platform 2, enabling them to move different storage slots 201 to the inlet / outlet 103 for feeding and placement. It also facilitates the subsequent rotation of the required sampling and storage containers 4 to the inlet / outlet 103 for retrieval. The overall operation is simple and user-friendly.

[0027] Furthermore, the inner wall of the storage compartment 201 is provided with a rubber sleeve 202. The rubber sleeve 202 is used to protect the sampling storage container 4. When the sampling storage container 4 is stored, it is embedded in the channel of the rubber sleeve 202. The rubber sleeve 202 is elastic and can fit against the outside of the sampling storage container 4, so that the sampling storage container 4 is restricted by the rubber sleeve 202 and is less likely to fall off when carried. In addition, when the box 1 is impacted, the rubber sleeve 202 can also reduce the impact force and prevent the sampling storage container 4 from directly contacting the inner wall of the storage compartment 201, thereby improving the safety of placement.

[0028] Please see Figure 3 , Figure 4 The bottom of the storage compartment 201 is provided with a lifting opening 203. A lifting assembly 3 is installed below the lifting opening 203. The lifting assembly 3 includes a lifting slide 301. A first slider 302 is provided inside the lifting slide 301. A lifting rod 305 is installed at the upper end of the first slider 302. A sliding groove 101 is provided on the side wall of the box 1. An adjusting handle 303 is installed on the outer wall of the first slider 302. A second slider 304 is provided on both sides of the adjusting handle 303 near the end.

[0029] When the sampling storage container 4 is to be removed, the first slider 302 is moved upward by extending to the adjusting handle 303, so that the first slider 302 moves upward in the lifting slide 301, and the lifting rod 305 is inserted into the storage slot 201 through the lifting port 203, so that the sampling storage container 4 in the storage slot 201 is lifted upward to the inlet and outlet 103, thereby making it convenient for the user to take it out; the second slider 304 is used to slide in the slide 101, and this position also moves when the user adjusts the lifting.

[0030] Please see Figure 5 , Figure 6 The sampling and storage container 4 includes a tube body 401 and a tube cap 402. The upper end of the tube body 401 is provided with a threaded head 4011, and the inner wall of the tube body 401 is provided with an internal thread 4021. The inner top of the tube cap 402 is provided with a bayonet 404, and sampling rods 403 of different shapes are installed inside the bayonet 404. An identification plate 405 is provided in the slot at the top of the tube cap 402.

[0031] The pipe cap 402 is opened and closed by rotating the internal thread 4021 and the threaded head 4011 of the pipe body 401. The pipe cap 402 is also equipped with a sampling rod 403 by a bayonet 404. The sampling rod 403 has different shapes, such as those with sampling blades or sampling cotton swabs, to facilitate the user's sampling operation. The bayonet 404 makes it easy for the user to disassemble and replace the sampling rod. The identification plate 405 can be observed through the inlet and outlet 103 when rotating and switching the sampling storage container 4, so that the user can distinguish different sampling storage containers 4 according to the identification plate 405.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
