[0092] Embodiment 4:

[0093] According to the second embodiment and the third embodiment, the extrusion mass ratio of the first paste and the second paste is obtained:

[0094] In this embodiment, if Figure 7 , the toothpaste body 200 is cylindrical, the cross section of the cavity is a regular circle, and the partition is in the middle of the cavity, so that the cross section of the first storage cavity 201 is a semicircular shape, and the cross section of the second storage cavity 202 is a semicircular shape. Then the first storage cavity 201 and the second storage cavity 202 have the same cross section, and the first storage cavity 201 and the second storage cavity 202 are equal in size.

[0095] In this embodiment, the inner cavity radius is 1.8 cm, and the cross-sectional area of ​​the cavity is 10.1736 cm 2 , the cross-sectional area of ​​the first storage cavity 201 and the second storage cavity 202 is 5.087 cm 2 .

[0096] In this embodiment, the number of teeth of the first transmission gear is 11, the number of teeth of the second transmission gear is 11, and the number of teeth of the driving gear is 24, so the gear ratio of the driving gear to the first transmission gear is 2.182.

[0097] The diameter of the first screw rod and the second screw rod is 3.3 cm. In this embodiment, the lead of the first screw rod and the second screw rod is 0.192 cm.

[0098] If the driving gear rotates 60 degrees, the number of revolutions of the driving gear is 60 / 360, which is 0.167 revolutions.

[0099] Then the distance that the first extrusion on the first screw rod and the second extrusion on the second screw rod move downward is the product of "the number of rotations of the driving gear" and "the lead of the first screw rod and the second screw rod" and "the tooth ratio of the driving gear to the first transmission gear", which is 0.167×2.182×0.192, which is 0.070 cm.

[0101] The quality of the extruded paste can be obtained through the volume of the extruded paste and the density of the paste.

[0102] In this embodiment, the density of the paste in the first storage cavity 201 is 1.3 g / cm3, and the density of the paste in the second storage cavity 202 is 1.43 g / cm3.
