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.

The utility model discloses a bionic service type humanoid robot mouth structure which comprises a sensory system and a mouth system connected with the sensory system, and the mouth system comprises a jaw structure, a tooth structure, a lip structure and a tongue structure. The jaw structure, the tooth structure, the lip structure and the tongue structure receive control signals sent by the sensory system to execute corresponding motions, the sensory system is formed by the sensing center, the sensor network, the signal processing unit and the execution unit, timely and effective feedback can be made to external environment changes, and the interaction capacity with the outside is greatly improved; meanwhile, according to the taste sensor, the humanoid robot can test and evaluate the food under the condition that no human testee exists, and the taste sensing system can simulate the function of a human taste sensing system, so that the taste of the food is automatically evaluated.
