Facial exercise device
An ornamental design for a facial exercise device, as shown in the figures and description. The facial exercise device is used to strengthen, tighten, and tone the midface, lower face, orofacial region, and oropharynx (including the tongue and floor of the mouth muscles) for both aesthetic and rehabilitative therapeutic purposes. The facial exercise device comprises a trapezoidal tubular body having a primary isosceles trapezoidal shape. The trapezoidal tubular body defines a plurality of openings with equally spaced compressible and bendable body members centered around a central opening, positioned at predetermined locations for isometric and isotonic muscle resistance training for various facial and tongue movements. The facial exercise device can be positioned anywhere, including under the lower lip, under the upper lip, under both lips, on one or both cheeks, around the outer periphery of the mouth, and within the oral cavity (contacting the hard palate, tongue surface, and floor of the mouth). 1.1) Perspective view; 1.2) Front view; 1.3) Plan view; 1.4) Bottom view; 1.5) Right side view; 1.6) Left side view; 1.7) Rear view; 1.8) Cross section; 1.9) Reference view showing the state of use; 1.10) Reference view showing the state of use

Sealing device for a homogeniser and homogeniser
The application discloses a sealing device of a homogenizer and the homogenizer. The sealing device comprises a piston and a plunger. The piston comprises a first lip and a second lip on a side of the piston facing the plunger. The first lip and the second lip are arranged in sequence and are spaced apart in the axial direction of the plunger. The first lip and the second lip are arranged around and are attached to the outer circumferential surface of the plunger. The double-lip structure of the first lip and the second lip arranged on the side of the piston facing the plunger is used to scrape off the material adhered to the plunger. The second lip is used to prevent the residual material generated by the friction between the first lip and the plunger from entering the space between the plunger and the piston, thereby improving the sealing effect and prolonging the service life of the sealing device.
