[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0030] Embodiment 1:

[0031] Referring to Figures 1-5 , an easy-to-clean vacuum distillation kettle includes a kettle body 1 and a head 101. The head 101 is fixedly connected to the bottom of the kettle body 1, and further includes:

[0032] A driving motor 2, fixedly connected to the kettle body 1;

[0033] A driving rod 201, fixedly connected to the driving end of the driving motor 2;

[0034] A first stirring rod 3, fixedly connected to the driving rod 201;

[0035] A plug plate 4, connected to the head 101;

[0036] An insert rod 402, fixedly connected to the plug plate 4;

[0037] A slide plug 302, slidably connected in the first stirring rod 3;

[0038] The insert rod 402 and the slide plug 302 are connected;

[0039] A second stirring rod 301, fixedly connected to the first stirring rod 3;

[0040] The airbag 3011 is fixedly connected to the second stirring rod 301.

[0041] An air delivery pipe 3012 is fixedly connected in the second stirring rod 301, and the airbag 3011 is communicated with the first stirring rod 3 through the air delivery pipe 3012.

[0042] A connection card 305 is fixedly connected to the bottom of the sliding plug 302. A first magnet 3051 is fixedly connected in the connection card 305. A second magnet 4021 is fixedly connected to the inserting rod 402. The first magnet 3051 and the second magnet 4021 attract each other.

[0043] A support rod 1012 is fixedly connected to the bottom of the head 101. A third magnet 1011 is fixedly connected to the support rod 1012. A fourth magnet 401 is fixedly connected to the side wall of the plugging plate 4. The third magnet 1011 and the fourth magnet 401 attract each other.

[0044] By setting the third magnet 1011 and the fourth magnet 401 to attract each other, the stability of the plugging plate 4 after installation can be further improved.

[0045] Refer to Figures 1-5 , the staff holds the plugging plate 4 by hand. After alignment, the plugging plate 4 is inserted into the head 101. The material to be distilled is added into the kettle body 1. At this time, a heating medium is input into the jacket of the kettle body 1 for heating and distillation. During the distillation process, the driving motor 2 is started. The driving motor 2 will drive the driving rod 201 connected to its driving end to rotate. The rotation of the driving rod 201 will drive the first stirring rod 3 to rotate. The rotation of the first stirring rod 3 will drive the second stirring rod 301 to rotate. Through the cooperation of the first stirring rod 3 and the second stirring rod 301 for stirring, the material in the kettle body 1 can be effectively evaporated.

[0046] Refer to Figure 3 , when the plugging plate 4 is inserted into the head 101, the inserting rod 402 on the plugging plate 4 will be synchronously inserted into the first stirring rod 3. And at this time, the second magnet 4021 will attract the first magnet 3051. At this time, the inserting rod 402 will be stably connected to the sliding plug 302.

[0047] When the distillation is over, the staff can manually pull out the plugging plate 4. When the staff pulls the plugging plate 4 outwards, the plugging plate 4 will drive the insertion rod 402 to move downward. When the insertion rod 402 moves downward, it will pull the sliding plug 302 to move downward. When the sliding plug 302 moves downward, it will press the gas in the first stirring rod 3 into the airbag 3011. At this time, the airbag 3011 will be inflated and bulged. When the sliding plug 302 slides to the maximum limit, the airbag 3011 abuts against the side wall of the head 101. At this time, the driving motor 2 continues to drive the second stirring rod 301 to rotate. At this time, the airbag 3011 will rub against the inner wall of the head 101, and then quickly scrape off the solid residues on the inner wall of the head 101, so that it is no longer necessary for the staff to reach into the head 101 for manual cleaning, improving the cleaning efficiency of the solid residues.

[0048] After sufficient cleaning, the staff can pull the plugging plate 4 outwards again. At this time, the first magnet 3051 is separated from the second magnet 4021, and at this time, the plugging plate 4 is completely removed from the head 101.

[0049] It should be noted that the head 101 is an arc head to ensure that the scraped residues can effectively roll out.

[0050] It should also be noted that the airbag 3011 is a wear-resistant airbag, and irregular patterns are provided on the surface of the airbag 3011 in contact with the head 101 to improve the scraping effect on the solid residues.

[0051] A one-way valve 3013 is provided on the air delivery pipe 3012.

[0052] A one-way intake valve 303 is fixedly connected to the side wall of the first stirring rod 3.

[0053] A one-way pressure relief valve 3014 is also fixedly connected to the second stirring rod 301.

[0054] It should be noted that the one-way valve 3013, the one-way intake valve 303 and the one-way pressure relief valve 3014 are all control valves that can be purchased on the market.

[0055] A spring 304 is fixedly connected to the sliding plug 302, and the end of the spring 304 away from the sliding plug 302 is fixedly connected to the first stirring rod 3.

[0056] Refer to Figure 3 , through the spring 304 provided on the sliding plug 302, the sliding plug 302 can be quickly reset.

[0057] The two groups of stirring rods provided in the device can fully disturb the materials in the kettle body 1, and then distill them sufficiently. At the same time, after the distillation is completed, the airbag 3011 provided on the second stirring rod 301 rotates, and then it can effectively scrape off the solid residues on the inner wall of the head 101, solving the problem that in the prior art, workers need to reach into the head 101 for manual cleaning, which is inconvenient and has low cleaning efficiency.

[0058] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
