The physiotherapy device includes a vibration capsule. The vibration capsule further includes a shell, a vibration motor being placed in the shell, a control panel connecting with the vibration motor electrically, and one or more batteries connecting with the vibration motor and the control panel electrically. The vibration motor includes a rotor closed to an end of the shell and a rotary magnet fixed on the rotor. ## Claims ### Claim 1 A physiotherapy device comprising: a vibration capsule, configured to navigate through a digestive track of a patient and to reduce constipation, the vibration capsule comprising: a shell configured to protect components in the shell from being corroding; a column-shaped vibration motor set in the shell; a control panel connecting with the column-shaped vibration motor electrically; one or more batteries connecting with the column-shaped vibration motor and the control panel electrically; and a fan holder, placed in the shell, being perpendicular to a horizontal axis of the shell and, configured to secure the column-shaped vibration motor closer to a hemispheric head of the shell and to keep a shape of the vibration capsule from being changed, and wherein the fan holder is placed close to an end of a rotor of the column-shaped vibration motor; wherein the column-shaped vibration motor comprising: the rotor disposed close to the hemispheric head of the shell, and a rotary magnet fixed on the rotor, configured to create a rotational magnetic field in the digestive track of the patient, wherein the rotary magnet comprises a plurality number N of magnetic bodies, while N being an integer not less than 2, having a first magnetic body separated from its adjacent magnetic body by a distance, and poles of the first magnetic body and its adjacent magnetic body are placed in a reverse direction; the distance between the first magnetic body and its adjacent magnetic body is varied thereby adjusting an attenuation of the rotational magnetic field of the rotary magnet; and a change in an attenuation of rotational magnetic field of the plurality of magnetic bodies is milder than a change in rotational magnetic field of the first magnetic body, wherein a range of the rotational magnetic field of the rotary magnet is set as a value from 0.06 T to 0.5 T; wherein the control panel comprises a microprocessor for programming working mode of the column-shaped vibration motor, a magnetic sensor, and a current amplification chip; and wherein a rotation speed of the rotor is set as a value from 100 revolutions per minute to 15000 revolutions per minute. ### Claim 2 (depends on 1) The physiotherapy device according to claim 1, wherein the column-shaped vibration motor, the control panel and the one or more batteries are placed in sequence along an axial direction of the shell. ### Claim 3 (depends on 1) The physiotherapy device according to claim 1, wherein the rotary magnet is fixed on a surface of the rotor which is far away from the one or more batteries, or is fixed on a lateral surface of the rotor. ### Claim 4 (depends on 1) The physiotherapy device according to claim 1, wherein each of the plurality number N of magnetic bodies is a Neodymium (NdFeB) magnet, a ferroferric oxide magnet, or a cobalt-nickel magnet. ### Claim 5 (depends on 1) The physiotherapy device according to claim 1, further comprising: a magnetic base is disposed in connection with the vibration capsule; the vibration capsule comprising a reed switch that cooperates with the magnetic base to turn on or turn off the vibration capsule; the reed switch is connected with the control panel electrically; and the reed switch located between the column-shaped vibration motor and the shell. ### Claim 6 (depends on 1) The physiotherapy device according to claim 1, wherein the shell is a biocompatibility shell. ### Claim 7 (depends on 1) The physiotherapy device according to claim 1, wherein the rotor is an eccentric rotor. ### Claim 8 (depends on 7) The physiotherapy device according to claim 7, wherein the eccentric rotor comprises a material having a density greater than 6-20 g/cm3.
