[0027] 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 of 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.

[0028] like Figure 1 and Figure 2 As shown, the multi-stage condensation device for producing natural plant essential oils includes a base plate 1 , an inclined box body 2 is arranged above the base plate 1 , and a support rod 21 is arranged at the lower end of the box body 2 to be fixed to the base plate 1 .

[0029] like Figure 1 As shown, a condenser 3 is provided in the box body 2, and the condenser 3 runs through the entire box body 2 along an inclined direction and is fixedly connected to the box body 2. Water and oil vapor enter from the inclined upper end of the condenser 3, and flow out from the inclined lower end after being condensed and liquefied;

[0030] like Figure 2 and Figure 3 As shown, a spiral cooling water pipe 4 is fixed in the box body 2, and the cooling water pipe is wound around the outside of the condenser tube 3, and the inlet and outlet of the cooling water pipe both penetrate the top of the box body 2 and are fixed to the box body 2. Cold water enters the cooling water pipe from the inlet, passes through the outside of the condenser tube 3 to cool down the water and oil vapor therein, and then is discharged from the outlet, so as to ensure that there is always cooling water in the cooling water pipe 4;

[0031] The opposite sides of the box body 2 are open, and each is fixed with a protective plate 5, and the two protective plates 5 are provided with a plurality of through slots to facilitate the exchange of air inside the box body 2; Figure 4 As shown, a plurality of fans 6 are installed on one of the protective plates. When the fans 6 rotate, airflow is generated on the condenser tube 3 to accelerate the cooling and the exchange of air inside the box. Combined with the heat exchange and cooling effect of the cooling water pipe 4, multi-stage condensation is achieved, thereby improving the condensation efficiency.

[0032] In this embodiment, the protective plate 5 and the box body 2 are fixed by bolts to facilitate the disassembly and maintenance of the fan 6, and also to facilitate the cleaning of the inside of the box body 2; in some embodiments, the protective plate 5 and the box body 2 can also be fixed by welding, but it is not easy to disassemble after welding.

[0033] It is worth mentioning that when the cooling water pipe 4 performs condensation operation (i.e., cold water flows), part of the air inside the box 2 (the air around the cooling water pipe 4) will be liquefied, and the liquefied liquid will drip into the box 2; therefore, in this embodiment, Figure 2 and Figure 3 As shown, a storage groove 22 is opened on the inner bottom surface of the box body 2, and a drainage groove 23 is opened at the oblique lower end of the storage groove 22, and a storage box 7 is fixed to the oblique lower end of the box body 2 by bolt connection. The liquefied liquid drips into the storage groove 22, and under the action of gravity, it will flow to the drainage groove 23 and fall into the storage box 7, so as to be collected centrally. After the liquid is full, the storage box 7 can be disassembled for emptying.

[0034] In addition, due to the exchange of air inside and outside the box 2 during the condensation process, external dust and impurities will enter the box 2, mix with the liquefied liquid, and stick to the storage groove 22, making it difficult to discharge outside the box 7. Therefore, in this embodiment, a scraper assembly 8 is installed in the storage groove 22 to scrape the impurities adhering to the bottom surface of the storage groove 22 out of the box 2;

[0035] like Figure 5 As shown, the scraper assembly 8 includes a scraper 81 that is slidably matched with the receiving groove 22. By controlling the scraper 81 to slide obliquely downward from the highest point, the impurities adhering to the bottom surface of the receiving groove 22 can be scraped to the drainage groove 23 and fall into the receiving groove 22, thereby ensuring the cleanliness of the interior of the box body 2;

[0036] In this embodiment, a screw rod 82 is rotatably connected to the box body 2, and the screw rod 82 obliquely penetrates the scraper 81 and is threadedly connected thereto. By rotating the screw rod 82, the scraper 81 can be driven to slide; and in order to ensure that the scraper 81 remains stable at the highest point, the screw rod 82 needs to have self-locking properties, that is, the thread lead angle of the screw rod 82 is less than the equivalent friction angle;

[0037] Since the environment inside the box body 2 is relatively humid, in order to prevent the screw rod 82 from rusting, the screw rod 82 can be made of stainless steel or plastic.

[0038] Of course, the method of driving the box body 2 to slide includes but is not limited to the screw rod 82 in this embodiment. In some embodiments, the scraper 81 can also be directly driven to slide by setting linear driving components such as electric push rods and telescopic rods on the box body 2.

[0039] Working principle:

[0040] By setting a condenser tube 3 tilted downward in the box 2, and winding a spiral cooling water pipe 4 outside the condenser tube 3, the water and oil vapor in the condenser tube 3 is cooled, and multiple fans 6 are fixed on a side protective plate 5 of the box 2. The airflow generated by the fans 6 blows toward the condenser tube 3, and can accelerate the exchange of air inside and outside the box 2, so as to achieve multi-stage condensation of water and oil vapor, so as to achieve the purpose of improving condensation efficiency. By opening a storage groove 22 on the bottom surface of the box 2, the liquid generated by the liquefaction of air around the cooling water pipe 4 is stored, and a drainage groove 23 is opened at the oblique lower end of the storage groove 22, and a storage box 7 is set at the lower end of the box 2 to store the liquid discharged from the drainage groove 23. By setting a scraper assembly 8 in the clearance groove 22, the impurities adhering to the clearance groove 22 are scraped out of the box 2, so as to clean the box 2 and ensure its cleanliness.
