[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 As shown, a mixing device for a liquid mixer with high mixing efficiency includes a support frame 1, a support leg 2 fixedly installed at the bottom of the support frame 1, water spray heads 3 fixedly installed in an array on both sides inside the support frame 1, an expandable protective mechanism 4 symmetrically installed at the top of the support frame 1, and a mixing mechanism 5 fixedly installed in the middle position inside the support frame 1.

[0022] like Figure 2As shown, the spray head 3 includes a retainer 301 and a high-pressure water nozzle 302. The retainer 301 is made of a hollow ball bearing. The high-pressure water nozzle 302 is fixedly installed on one side of the rotating shaft inside the retainer 301 so that the high-pressure water nozzle 302 can be automatically rotated to clean the stirring shaft 504 and stirring paddle 506 from multiple angles after stirring, which is less likely to cause cross-contamination and extends the service life of the stirring shaft 504 and stirring paddle 506.

[0023] like Figure 2 As shown, the protective mechanism 4 includes lifting rolling bearings 401, which are fixedly installed on both sides of the upper end of the support frame 1. A rotating shaft 402 is fixedly installed between the lifting rolling bearings 401. A protective curtain 403 is fixedly installed on the rotating shaft 402, and one end of the protective curtain 403 is wound and rolled up on the rotating shaft 402. A drive motor 404 is fixedly installed on one side of the support frame 1. The output end of the drive motor 404 is fixedly connected to the rotating shaft 402 so that the protective mechanism 4 can automatically close and open, so as to protect personnel safety and prevent water from splashing everywhere during cleaning.

[0024] like Figure 3 As shown, the stirring mechanism 5 is installed in the middle position of the upper part of the support frame 1. The stirring mechanism 5 includes a stirring rolling bearing 501. A stirring motor 502 is installed directly above the stirring rolling bearing 501. The output end of the stirring motor 502 is fixedly installed on the inner ring of the stirring rolling bearing 501 so as to provide power to the stirring shaft 504 and the stirring paddle 506.

[0025] like Figure 3 As shown, a telescopic rod 503 is rotatably mounted below the stirring motor 502. The upper part of the telescopic rod 503 is fixedly connected to the output end of the stirring motor 502 to facilitate the use of different mixing tanks and control the depth of the stirring paddle 506 in the mixing tank during stirring, so as to more thoroughly mix the liquid.

[0026] like Figure 3 and Figure 4 As shown, a stirring shaft 504 is installed at the lower end of the telescopic rod 503. The upper end of the stirring shaft 504 and the inner wall of the lower end of the telescopic rod 503 are provided with interlocking threads 505. A propulsion-type stirring paddle 506 is fixedly installed on the stirring shaft 504 to facilitate the replacement of different stirring shafts 504 and stirring paddles 506. When dealing with different liquids or to achieve different effects, a more suitable stirring shaft 504 and stirring paddle 506 can be replaced.

[0027] like Figure 2 As shown, guide rails 6 are vertically fixed on both sides of the inner ends of the support frame 1. The protective curtains 403 are respectively snapped into the relatively distributed guide rails 6 to provide guidance for the protective curtains 403, limit the swing range of the protective curtains 403, and prevent swaying.

[0028] like Figure 1 As shown, the lower end of the support leg 2 is fixedly equipped with casters 7, and the casters 7 are equipped with locking locks 8 to facilitate flexible movement and fixation of the mixing equipment, reduce the difficulty of moving the mixing equipment, facilitate equipment combination and layout adjustment, and protect the ground and the equipment itself.

[0029] In use, the mixing equipment is moved to the appropriate position using the casters 7. The telescopic rod 503 extends to place the mixing shaft 504 and the mixing paddle 506 into the mixing tank. The mixing motor 502 is then turned on to start operation. During cleaning, the protective curtain 403 is lowered, and the water spray head 3 automatically cleans the mixing shaft 504 and the mixing paddle 506, avoiding potential hygiene dead spots caused by manual cleaning, preventing cross-contamination, ensuring that the mixing equipment is always in good working condition, and extending its service life. The installed protective curtain 403 can effectively prevent personnel from accidentally touching the switch and avoid the danger of injury caused by the mixing paddle 506 due to accidental start-up, thus comprehensively protecting the personal safety of operators and reducing the possibility of safety accidents.
