The invention provides an oil seal with a bidirectional sealing structure and a production process thereof, the oil seal comprises an oil seal main body, a first lip and a second lip, the first lip and the second lip are arranged on the inner ring wall of the oil seal main body side by side in the axial direction of the oil seal main body, and the first lip, the second lip and the oil seal main body are integrally formed; the first lip is bent towards an outer opening, the second lip is bent towards an inner opening, and the first lip and the second lip are used for being in interference fit with a rotating shaft so as to achieve bidirectional sealing of the rotating shaft in the vertical direction. By the adoption of the integrated lip, installation is easier and more convenient, other parts are simplified, the structure is simpler, the part demand quantity is smaller, and the production and manufacturing cost is lower. And the lip structures facing the opposite directions are arranged, the inner side and the outer side of the oil seal are sealed correspondingly, two-way sealing can be achieved, the sealing effect is better, the installation space can be reduced, and applicability is higher.

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.

The invention provides a combined oil seal with a reverse lip structure, which comprises a lip I and a lip II which can be in contact sealing with a rotating shaft, an oil side angle alpha 1 is formed between a front lip of the lip I and the rotating shaft, and an air side angle beta 1 is formed between a rear lip of the lip I and the rotating shaft; the front lip of the lip II and the rear lip of the lip I are oppositely arranged; an air side angle beta'is formed between the front lip of the lip II and the rotating shaft, and an oil side angle alpha 'is formed between the rear lip of the lip I and the rotating shaft, so that the lip I and the lip II form a reverse lip structure. According to the design method of the combined oil seal with the reverse lip structure, for the combined oil seal, one lip can seal an oil medium, the other lip can resist foreign matter and water media, compared with a traditional oil seal, the foreign matter and water medium resisting sealing capacity can be remarkably improved, and the reliability of the oil sealing lip on the inner side can be guaranteed.
