[0021] The specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings. A new type of food taking port device of the present invention includes a gear plate 1, a shading sheet 2, a travel switch 3, a gear assembly 4, an arc opening and closing plate assembly 5, a panel 6, a trapezoidal opening and closing plate assembly 7, a roller assembly 8, a motor mounting plate 9, and a motor 10. The pair of arc opening and closing plate assemblies 5 and a pair of trapezoidal opening and closing plate assemblies 7 are respectively fixed on the panel 6. The gear plate 1 is located above the arc opening and closing plate assembly 5 and the trapezoidal opening and closing plate assembly 7. The three sets of gear assemblies 4 and one set of roller assemblies 8 are evenly distributed around the gear plate 1. The motor mounting plate 9 is installed on the motor 10, and the motor mounting plate 9 is fixed on the gear assembly 4. The pair of travel switches 3 are respectively fixed on the inner sides of two adjacent gear assemblies 4. The pair of shading sheets 2 are fixed on the gear plate 1 and correspond to the pair of travel switches 3.

[0022] The gear assembly 4 has three sets, each including an M5 ball screw 41, a top plate 42, a bearing 43, a gear 44, and a base 45. The M5 ball screw 41 is fixed on the top plate 42, the two bearings 43 are respectively inserted into the holes of the top plate 42 and the base 45, the gear 44 is located between the top plate 42 and the base 45, and the top plate 42 is fixed on the base 45.

[0023] The roller assembly 81 includes an M5 ball screw 42, a top plate 42, a bearing 43, a roller 81, and a base 45. The M5 ball screw 41 is fixed to the top plate 42, the two bearings 43 are respectively inserted into the holes of the top plate 42 and the base 45, the roller 81 is located between the top plate 42 and the base 45, and the top plate 42 is fixed to the base 45.

[0024] The two sets of trapezoidal opening and closing plate components 5 each include a slider housing 71, a movable slider 72, a spring, an M4 ball screw 75, a trapezoidal plate 74, and a nylon sleeve 73. The inner hole of the spring 76 is sleeved on the side cylindrical boss of the movable slider 72, and the spring 76 and the movable slider 72 are installed together in the inner cavity of the slider housing 71, and the upper boss of the movable slider 72 is matched with the waist groove of the slider housing 71. The slider housing 71 is fixed on the trapezoidal plate 74, and the two M4 ball screws 75 are screwed into the threaded holes of the trapezoidal plate 74. The trapezoidal plate 74 is sleeved on the nylon sleeve 73, and the trapezoidal plate 74 can move linearly on the nylon sleeve 73.

[0025] The two sets of arc opening and closing plate assemblies 5 each include a fixed slider 51, an M4 ball screw 75, an arc plate 52, and a nylon sleeve 73. The fixed slider 51 is fixed on the arc plate 52, the two M4 ball screws 75 are screwed into the threaded holes of the arc plate 52, the arc plate 52 is inserted into the nylon sleeve 73, and the arc plate 52 can move linearly on the nylon sleeve 73.

[0026] The gears 44 on the three sets of gear assemblies 4 mesh with the gear plate 1, and the three sets of gear assemblies 4 are respectively fixed on the panel 6. The roller 81 of the roller assembly 8 is tangent to the circular arc surface without teeth of the gear plate 1, and the roller assembly 8 is fixed on the panel 6. The four waist-shaped grooves inside the gear plate 1 are respectively matched with the upper bosses of the fixed sliders 51 of the two sets of circular arc opening and closing plate assemblies 5, and are also respectively matched with the upper bosses of the movable sliders 72 of the two sets of trapezoidal opening and closing plate assemblies 7.

[0027] The output shaft of the motor 10 is matched and fixed with the inner hole of the gear 44 on a set of gear assemblies 4. If the motor 10 rotates forward, the driving gear 44 will drive the gear plate 1 to rotate, and the light shielding sheet 2 on it will also rotate together. The four waist-shaped grooves of the gear plate 1 will push the upper bosses of the fixed sliders 51 of the two sets of circular arc opening and closing plate assemblies 5, and also push the upper bosses of the moving sliders 72 of the two sets of trapezoidal opening and closing plate assemblies 7. Therefore, the fixed slider 51 drives the circular arc plate 52 to move outward, and the moving slider 72 also drives the trapezoidal plate 74 to move outward. When the corresponding light shielding sheet 2 rotates to the open travel switch 3, the motor 10 stops, and the window is at the maximum opening at this time. Similarly, the motor 10 reverses and drives the gear plate 1 to rotate with the driving gear 44, and the shading sheet 2 thereon also rotates together. The four waist-shaped grooves of the gear plate 1 will push the upper bosses of the fixed sliders 51 of the two sets of circular arc opening and closing plate assemblies 5, and also push the upper bosses of the movable sliders 72 of the two sets of trapezoidal opening and closing plate assemblies 7. Therefore, the fixed slider 51 drives the circular arc plate 52 to move inward, and the movable slider 72 also drives the trapezoidal plate 74 to move inward. When the corresponding shading sheet 2 rotates to the closed travel switch 3, the motor 10 stops, and the window is in a closed state at this time.

[0028] When the two arc-shaped plates 52 and the two trapezoidal plates 74 move inward, if there is a foreign object in between, the trapezoidal plates 74 will touch the foreign object first, and the spring 76 in the trapezoidal opening and closing plate assembly 7 will be compressed, and the trapezoidal plates 74 will stop moving due to resistance. When the foreign object is taken out, the trapezoidal plates 74 can continue to move until the window is closed to prevent the foreign object from being pinched and damaged.

[0029] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes in form and details may be made to the present invention without departing from the spirit and scope of the invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
