Description

Technical Field

[0001] The utility model relates to the technical field of food detection, in particular to a portable food pesticide residue and heavy metal content detection device. Background Art

[0002] According to a portable food pesticide residue and heavy metal content detection device disclosed in China New Utility Model Publication CN209372829U, the utility model is provided with a dissolution chamber, which can quickly dissolve finely crushed samples, making them easier to detect. A stirring mechanism, a pesticide concentration detector and a heavy metal concentration detector are provided in the dissolution chamber. The stirring mechanism accelerates the dissolution of the solvent and the sample. By turning on the detection switch, the pesticide concentration detector and the heavy metal concentration detector can detect the concentration of the dissolved sample in the first time, making the detection more accurate and quick.

[0003] However, when the device is in use, because it grinds the test food twice and then uses a stirring mechanism to mix the solution and the grinded food for testing, because the solvent and the sample are dissolved in the dissolution chamber, the mixture will stick to the inner wall of the dissolution chamber, and the above-mentioned device is not equipped with a corresponding cleaning mechanism. The mixture adhering to the chamber will affect the subsequent detection of other samples. In order to solve this problem, we propose a portable food pesticide residue and heavy metal content detection device. Utility Model Content

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Embodiment 1

[0035] See also Figure 1-4The portable food pesticide residue and heavy metal content detection device comprises a detection device 1, wherein the detection device 1 comprises: a housing 11, a motor 12 is arranged on the top thereof, the output end of the motor 12 penetrates the housing 11 and is fixedly connected to a stirring shaft 13; a crushing roller 14 is arranged inside the housing 11; a detector 15 is arranged on the housing 11; a portable bracket is arranged at the bottom of the housing 11, the housing 11 and the portable bracket are fixedly connected, and a trapezoidal feed port is arranged on the outer wall of the housing 11. There are two detectors 15, namely a pesticide detector and a heavy metal detector, and the detection head 16 is used correspondingly to the detector 15. When the user tests the food, he first puts the food sample into the shell 11 from the feed port. The feed port is trapezoidal and its bottom is a slope, so that the tested food can better enter the shell 11. After the food enters, the motor 12 is turned on. The output end of the motor 12 passes through the top of the shell 11 and is fixedly connected to the stirring shaft 13. Therefore, the motor 12 controls the stirring shaft 13 to rotate. After the stirring is completed, the electric telescopic rod 23 is controlled to be retracted to make the food sample fall to the crushing roller 14. The crushing roller 14 is two rollers with a close distance between them. The food sample is further crushed by squeezing. The crushed food sample falls downward to the bottom of the shell 11 and can be detected by the detection head 16 to check whether there are pesticide residues and heavy metal content data in its components, and the data is displayed on the detector 15.

[0036] The detection device 1 is provided with a cleaning device 2, and the cleaning device 2 includes: a liquid injection port 21, which is provided at the top of the shell 11; a scraper 22, which is provided on the outer wall of the stirring shaft 13; an electric telescopic rod 23, which is provided at the bottom of the stirring shaft 13 and the electric telescopic rod 23 passes through the shell 11; a cavity 24, which is provided at the bottom of the crushing roller 14, and two detection heads 16 are provided on the side wall of the cavity 24, and a motor 25 is provided at the bottom of the cavity 24, and the output end of the motor 25 passes through the cavity 24 and is fixedly connected to the stirring shaft 251, and the outer wall of the stirring shaft 251 is fixedly connected with a brush layer 252. After the detection is completed, the inside of the shell 11 needs to be cleaned, otherwise the food residues of the previous batch will affect the detection of the next batch. The cleaning solvent is injected into the shell 11 through the liquid injection port 21, and then the motor 12 is turned on. The motor 12 controls the stirring shaft 13 to rotate and drive the scraper 22 to scrape the inner wall of the shell 11. After a period of cleaning, the electric telescopic rod 12 is turned on to allow the solvent to enter the cavity 24 downward. During the flow process, the solvent cleans the crushing roller 14. The motor 2 25 is turned on. The motor 25 drives the stirring shaft 251 to connect to the brush layer 252 to rotate to clean the detection head 16 and the inner wall of the cavity 24.

[0037] An electric telescopic rod 261 is provided on one side of the cavity 24, and the top telescopic rod of the electric telescopic rod 261 extends into the interior of the side wall of the cavity 24. A filter box 26 is provided behind the electric telescopic rod 261, and the filter box 26 is plugged into the housing 11. A water outlet is provided on the outer side wall of the housing 11 where the filter box 26 is located, and a valve is provided at the water outlet. After a period of cleaning, the solvent is inside the housing 11, and the electric telescopic rod 261 is opened. The top telescopic rod of the electric telescopic rod 261 contracts to expose the channel on the side of the cavity 24 so that the solvent enters the empty groove on the side of the housing 11. During the flow process, food residues are retained in the filter box 26. The filter hole on the left side of the filter box 26 is larger than the filter hole on the right side, so that the food residues cannot pass through the filter box 26. At the same time, the filter box 26 is plugged into the housing 11, and the filter box 26 can be pulled out for cleaning after the solvent is poured out of the detection device 1.

[0038] Embodiment 2

[0039] On the basis of the first embodiment, a function of repeatedly cleaning the interior of the detection device is added.

[0040] See also Figure 1-4 The shell 11 is provided with a micro water pump 27, and a water delivery pipe 28 is provided through the micro water pump 27, and one end of the water delivery pipe 28 passes through the bottom of the shell 11, and the other end passes through the top of the shell 11. After the user cleans the detection device 1 for the first time, the solvent carries the food residue from the shell 11 through the filter box 26 into the side of the shell 11, and then controls the electric telescopic rod 261 to close the cavity 24, opens the micro water pump 27, and the micro water pump 27 sucks water from the shell 11 through the water delivery pipe 28, and then enters the shell 11 from the top of the shell 11, repeats the previous cleaning process, and after cleaning several times, opens the water outlet valve on the outer wall of the shell 11, and dumps the detection device 1 to pour out the cleaning solvent.
