In order to achieve the purpose, the invention provides the following technical scheme: a sustainable output power system comprising:

the vibration motor is arranged in the electric toothbrush, and the output end of the vibration motor is connected with the eccentric rotor through the output shaft;

the vibration regulation and control device comprises a pressure sensing unit for detecting the pressure of the toothbrush head and a vibration increasing component connected with the eccentric rotor, and the pressure sensing unit is in signal connection with the vibration increasing component; the pressure sensing unit detects different pressure signals (because the toothbrush head is in contact with different parts of teeth, the stress conditions of the toothbrush bristles of different parts are different, so that the part of the toothbrush head in contact with the teeth can be judged according to the local stress difference), different signals are not given back to the vibration increasing component, the vibration increasing component adjusts different vibration output directions and sizes according to the pressure signals, because the toothbrush head is in contact with different parts of the teeth, such as the teeth, the gum contact part, the tooth side wall part and the tooth apposition part, the tartar removing modes are different, different tooth brushing modes can be increased in the vibration direction, for example, the tooth brush head is not suitable for vibrating in the length direction of the bristles in the connection part of the gum and the teeth, so that the gum can be stimulated, and if the vibration is too large, the gum can be injured, the bleeding is caused, and the vibration is needed in the direction vertical to the length, the tartar at the joint of the gum and the teeth is stripped, and in the direction of the teeth, because the slits are deeper, the toothbrush head needs to vibrate in the length direction of the toothbrush bristles, so that the toothbrush bristles enter the slits to remove the tartar in the slits, and because the tartar in the slits is deeper, the tartar needs to be removed by stronger vibration force;

the power generation module is used for converting mechanical energy of the toothbrush in reciprocating motion along the length direction of the toothbrush into electric energy, and because some people have the habit of alternately using an electric mode for brushing teeth and using a common toothbrush for brushing teeth, the power generation module is arranged in the toothbrush, and the kinetic energy of the toothbrush shaken by a user when the user does not use a vibration mode for brushing teeth is converted into the electric energy to be stored, so that the charging times are reduced, or the time of a battery in a low-power state is reduced, and the output time of the power is prolonged.

Preferably, be equipped with first induction zone, second induction zone and the third induction zone along its length direction distribution on the toothbrush head, first induction zone, third induction zone are located the both sides of second induction zone, be equipped with a list of continuous distribution in first induction zone, second induction zone and the third induction zone the forced induction unit, first induction zone and third induction zone are used for detecting the pressure of toothbrush head width direction both sides border brush hair, because the difference between gum and the tooth lies in, gum department surface distribution is even, and there is discontinuous recess tooth department, will cause at the length direction of toothbrush head like this, the toothbrush hair that lies in between the tooth can have great pressure differential, and the toothbrush hair pressure that lies in gum department is then relatively even, utilizes this difference then can control the vibrations direction and the intensity of toothbrush head when different positions, realizes better tooth brushing effect, and reduces the discomfort during the tooth brushing process.

Preferably, the distance between two adjacent pressure sensing units in the same row is equal to the distance between two adjacent tufts of bristles in the same row on the toothbrush head, so that the pressure difference between the two adjacent tufts of bristles can be detected, and if a larger pressure difference exists between the two adjacent tufts of bristles in one row and a larger pressure difference does not exist between the two tufts of bristles in a different row, it is indicated that one group of the two tufts of bristles is in the gap between the teeth, and the judgment and calculation can be performed.

Preferably, the vibration increasing component comprises two groups of vibration increasing parts which are parallel to the direction of the toothbrush head bristles and vertical to the direction of the toothbrush head bristles, the vibration increasing component comprises an electromagnetic coil connected with the vibration motor and a vibration magnetic block connected with the eccentric rotor in a sliding way, the electromagnetic coil and the vibrating magnetic block are mutually attracted or repelled, the vibration increasing component which is parallel to the direction of the toothbrush head bristles is positioned in the vertical direction of the eccentric rotor, the vibration increasing component which is vertical to the direction of the toothbrush head bristles is positioned on the left side and the right side of the eccentric rotor, the vibration increasing component has two states, one state is a vibrating state following the motion of the eccentric rotor, and the other state is a containing state not contacting with the eccentric rotor, when in a vibration state, the vibration generator moves together with the eccentric rotor, and because the movement is linear, the vibration is increased in the linear direction, so that the aim of enhancing the vibration sense in a certain specific direction is fulfilled.

Preferably, the vibration increasing components are symmetrically arranged in the radial direction of the output shaft, at least one group of vibration increasing components is arranged in the length direction of the eccentric rotor, the vibration sense in a certain direction is increased by using different numbers of vibration increasing components, and the vibration intensity in a certain direction can be controlled by controlling one group, two groups or three groups of vibration increasing components which vibrate in the same linear direction according to different numbers, so as to achieve better cleaning effect.
