[0044] like Figure 2 and 3 As shown, the imitation upper jaw movement component 1 of the present application includes an upper jaw component 17 and a first crank slider mechanism for controlling the up and down movement of the upper jaw component 17. The first crank slider mechanism includes a first eccentric wheel 11, a first motor 112 for driving the first eccentric wheel 11 to rotate, a first connecting rod 12, and a first sliding rod 14. The upper end of the first connecting rod 12 is rotatably connected to the first eccentric wheel 11, and the lower end of the first connecting rod 12 is rotatably connected to the upper end of the first sliding rod 14. The imitation upper jaw movement component 1 also includes a first fixed plate 19. The first sliding rod 14 is slidably installed on the first fixed plate 19, and the lower end of the first sliding rod 14 can drive the upper jaw component 17 to move up and down.

When the first eccentric wheel 11 rotates one circle, the first sensing plate 110 passes through the first sensor 111 once. When the first sensor 111 senses the first sensing plate 110, it can send a control signal to the first motor to control the first motor to pause slightly to imitate the rhythm of oral chewing.

[0046] A pressure sensor 15 is also provided between the lower end of the first sliding rod 14 and the upper jaw assembly 17 .

[0047] The upper jaw assembly 17 is also provided with a slider 16 , which is connected to the upper side of the upper jaw assembly 17 in a slidable manner left and right, and the lower end of the first sliding rod 14 is fixedly connected to the slider 16 .

[0048] like Figure 4As shown, the upper jaw assembly 17 includes an upper jaw body 171 and an upper cover 172 arranged on the upper jaw body 171. The upper jaw body 171 is provided with a cavity 174 with an opening facing upward. An elastic seal 173 is provided at the opening of the cavity 174. The upper cover 172 covers the opening of the cavity 174. The elastic seal 173 plays a sealing role. The upper jaw body 171 is also provided with two circulating water interfaces 175 that connect the cavity 174 with external circulating water.

[0049] The upper teeth 18 are installed under the upper jaw body 171. In a preferred embodiment, two upper teeth 18 installation grooves extending in the front-to-back direction are provided on the lower side of the upper jaw body 171, and the left and right sides of the upper teeth 18 installation grooves have clamping edges extending in the front-to-back direction, and the upper teeth 18 are provided with clamping grooves matching the clamping edges, and the upper teeth 18 are detachably installed in the upper teeth 18 installation grooves through the clamping grooves. This assembly method allows the upper teeth 18 to be taken out separately, which is convenient for disassembly and assembly, and convenient for cleaning the upper jaw.

[0050] The upper jaw body 171 is further provided with a first through hole 177 and a second through hole 178 . The first through hole 171 is used to inject saliva into the oral cavity, and the second through hole 178 is used to detect the odor in the oral cavity.

[0051] like Figure 5 As shown, the imitation mandibular component 6 of the present application includes a bottom wall, two side walls arranged on the left and right, and a rear wall located behind the two side walls. The bottom wall is provided with two rows of lower teeth 63 corresponding to the upper teeth 18. The upper jaw component 17 can be inserted into the imitation mandibular component 6 under the drive of the first crank slider mechanism, so that the upper teeth 18 and the lower teeth 63 are in contact and squeezed with each other. The two side walls of the imitation mandibular component 6 are provided with cheek films 61, and the bottom wall is provided with a tongue film 62. The rear wall of the imitation mandibular component 6 has a row of outlets 67.

[0052] The cheek film 61 and the tongue film 62 are made of transparent elastic films, which makes it convenient for experimenters to observe the food crushing process inside the oral cavity.

[0053] The inner surface of the cheek film 61 is in contact with the inner surface of the two side walls of the imitation mandibular component to form a smooth surface. The tongue film 62 is in contact with the inner surface of the bottom wall of the imitation mandibular component to form a smooth surface. In the imitation mandibular component, since the two side walls and the bottom wall are both smooth surfaces, it is easier to clean.

[0054] A first protrusion 176 is provided on one of the left and right side surfaces of the upper jaw body 171, a second protrusion 64 matching with the first protrusion 176 is provided on one of the side walls of the imitation mandibular component 6, and an elastic member 65 is provided on the other side wall of the imitation mandibular component 6. The elastic member 65 can apply a thrust to the upper jaw component 17. During the downward movement of the upper jaw component 17, the second protrusion 64 can squeeze the first protrusion 176, so that the upper jaw component 17 overcomes the thrust of the elastic member 65 and moves to the side close to the elastic member 65.

[0055] like Figure 6 and 8 As shown, in a preferred embodiment, the first protrusion 176 is a strip-shaped ridge with wedge-shaped upper and lower sides, and the second protrusion 64 is a strip-shaped ridge with an arc-shaped cross section. When the upper jaw component 17 moves up and down relative to the imitation lower jaw component 6, the first protrusion 176 and the second protrusion 64 squeeze each other and overcome the elastic force of the elastic member 65 to move toward the side close to the elastic member 65. When the first protrusion 176 and the second protrusion 64 are staggered from each other, the upper jaw component 17 moves to the side away from the elastic member 65 under the thrust of the elastic member 65, so that the upper jaw component 17 can swing left and right while moving up and down. Figure 8 As shown, the movement between the upper teeth 18 and the lower teeth 63 presents an elliptical shape, and the left and right friction of the upper and lower teeth 63 crushes the food, simulating the process of crushing and grinding the food in the oral cavity.

[0057] The cheek movement simulation component 2 also includes a second sensing sheet 26 installed on the second eccentric wheel 21 and a second sensor 27 corresponding to the second sensing sheet 26. When the second eccentric wheel 21 rotates one circle, the second sensing sheet 26 passes through the second sensor 27 once. When the second sensor 27 senses the second sensing sheet 26, it can send a control signal to the second motor to control the second motor to pause slightly, thereby imitating the movement pattern of the cheeks during chewing.

[0058] like Fig. 9 As shown, the tongue-imitation motion component 3 of the present application includes a third crank slider mechanism, an tongue-imitation top block 37 driven by the third crank slider mechanism, the third crank slider mechanism includes a third eccentric wheel 32, a third motor 31 driving the third eccentric wheel 32 to rotate, a third connecting rod 33, and a third sliding rod 34, one end of the third connecting rod 33 is rotatably connected to the third eccentric wheel 32, and the other end of the third connecting rod 33 is rotatably connected to one end of the third sliding rod 34, the tongue-imitation motion component also includes a third fixed plate 35, the third sliding rod 34 is slidably installed on the third fixed plate 35, and the end of the third sliding rod 34 can drive the tongue-imitation top block 37 to push the tongue film.

[0059] The tongue-imitation movement component also includes a third sensing plate 39 installed on the third eccentric wheel 32 and a third sensor 38 corresponding to the third sensing plate 39. When the third eccentric wheel 32 rotates one circle, the third sensing plate 39 passes through the third sensor 38 once.
