[0011] Preferably, a valve is fixedly installed on the outer surface wall of the discharge pipe.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are that

[0013] In the present utility model, when the water that has soaked vegetables and contains residual pesticides is in the mixing barrel, through the action of the control valve, the reagent in the reagent box quantitatively enters the mixing barrel along the infusion pipe, so that the reagent contacts it sufficiently.

[0021] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a thorough understanding of the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification.

[0023] Embodiment 1, as Figures 1-4 shown, the present utility model provides a vegetable pesticide residue detection device, which includes a temperature control box 1. A support plate 2 is fixedly installed on the inner surface wall of the temperature control box 1. A mixing barrel 3 is fixedly installed on the top of the support plate 2. A cross plate 4 is fixedly installed on one side of the outer wall of the mixing barrel 3. A reagent box 5 is fixedly installed on the top of the cross plate 4. An infusion tube 6 is fixedly penetrated through the bottom of the reagent box 5, and the output end of the infusion tube 6 is communicated with the inside of the mixing barrel 3. A control valve 7 is fixedly installed on the outer surface wall of the infusion tube 6. A heating device 8 is fixedly installed on the bottom of the inner wall of the temperature control box 1. A temperature sensor 9 is fixedly installed on one side of the inner wall of the temperature control box 1. A controller 10 is fixedly installed on one side of the outer wall of the temperature control box 1, and one side of the outer wall of the controller 10 is electrically connected to the outer surface wall of the temperature sensor 9.

[0024] The overall effect achieved by the entire Embodiment 1 is that when in use, first place the water that has soaked vegetables and contains residual pesticides in the mixing barrel 3. Then, a cross plate 4 is installed on one side of the outer wall of the mixing barrel 3, and a reagent box 5 is installed on the cross plate 4. And according to needs, open the control valve 7 installed on the infusion tube 6. Since the input end of the infusion tube 6 is communicated with the inside of the reagent box 5 and the output end of the infusion tube 6 is communicated with the inside of the mixing barrel 3, the reagent in the reagent box 5 can be quantitatively introduced into the mixing barrel 3 along the infusion tube 6 through the control valve 7. Secondly, the support plate 2 installed at the bottom of the mixing barrel 3 is fixedly installed on the temperature control box 1. A heating device 8 is fixedly installed on the bottom of the inner wall of the temperature control box 1. A temperature sensor 9 is installed on one side of the inner wall of the temperature control box 1, and the temperature sensor 9 is electrically connected to the controller 10 installed on one side of the outer wall of the temperature control box 1. Thus, the temperature inside the temperature control box 1 is monitored at all times through the temperature sensor 9, and the heating device 8 is controlled through the controller 10 to ensure that the internal temperature is the optimal temperature for the reagent to be mixed with the water containing residual pesticides, promoting sufficient contact between the reagent and it, thereby improving the accuracy of the detection result of vegetable pesticide residues.

[0025] Embodiment 2, as Figures 2-4As shown in the figure, a strip plate 11 is fixedly installed at the top of the mixing barrel 3. A driving motor 12 is fixedly installed at the top of the strip plate 11. A stirring assembly 13 is fixedly installed at the bottom of the driving motor 12. A protective cover 14 is placed on the top of the mixing barrel 3. A handle 15 is fixedly installed at the top of the protective cover 14. Two notches 16 are formed on the outer surface wall of the protective cover 14. A discharge pipe 17 is fixedly installed on the other side of the outer wall of the mixing barrel 3. The input end of the discharge pipe 17 is communicated with the inside of the mixing barrel 3. A valve 18 is fixedly installed on the outer surface wall of the discharge pipe 17.

[0026] The overall effect achieved by the entire Embodiment 2 is that when an appropriate amount of reagent and water containing residual pesticides are in the mixing barrel 3 and the temperature is always within the optimal temperature range, at this time, start the driving motor 12 installed on the strip plate 11 to drive the stirring assembly 13 to fully stir the mixture. At the same time, place the protective cover 14 on the mixing barrel 3 through the handle 15, effectively preventing foreign objects from falling into the mixing barrel 3 and avoiding affecting the accuracy of the detection results due to this. After a certain period of time, open the valve 18 installed on the discharge pipe 17, so that the mixed liquid in the mixing barrel 3 enters the next process along the discharge pipe 17 and is detected, so as to judge whether the pesticide residue on the vegetable exceeds the standard, thereby improving the use effect of the vegetable pesticide residue detection device.

[0027] Working principle: First, place the water that has soaked the vegetables and contains residual pesticides in the mixing barrel 3. Then place the corresponding reagent in the reagent box 5, and open the control valve 7 as needed, so that the reagent in the reagent box 5 quantitatively enters the mixing barrel 3 along the infusion pipe 6. At the same time, start the heating device 8 installed at the bottom of the inner wall of the temperature control box 1 through the controller 10. Since a temperature sensor 9 is installed on one side of the inner wall of the temperature control box 1, and the temperature sensor 9 constantly monitors the internal temperature and cooperates with the controller 10, the temperature inside the temperature control box 1 is always maintained at the optimal temperature for the mixture of the reagent and the water containing residual pesticides, so as to promote the full contact between the reagent and the water. Secondly, a strip plate 11 is installed on the top of the mixing barrel 3. Start the driving motor 12 installed on the strip plate 11 to drive the stirring assembly 13 to fully stir the mixture. Also, because a protective cover 14 is placed on the mixing barrel 3, it effectively prevents foreign objects from falling into the mixing barrel 3 and affecting the detection accuracy. After a certain period of time, open the valve 18, and let the mixed liquid combined with the reagent and the water containing residual pesticides enter the next detection process along the discharge pipe 17, so as to judge whether the pesticide residue on the vegetable exceeds the standard. Generally speaking, by fully combining the reagent and the water containing residual pesticides, the accuracy of the vegetable pesticide residue detection result is improved, and thus the use effect of the vegetable pesticide residue detection device is improved.

[0028] The above are only the preferred embodiments of the present utility model and do not limit the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
