An electric pump-type packaging tube for toothpaste, comprising a columnar storage cavity and a piston electric driving device provided therein, wherein one end of the storage cavity is a discharge port, and the other end is sealed by a piston, and the piston electric driving device is used for driving the piston to move a distance towards the discharge port and then stop moving,
- wherein, the electric pump-type packaging tube is an integral packaging tube and comprises a tube body;
- the tube body comprises a nozzle segment, a main body segment and a tail segment;
- a first end of the nozzle segment is provided with an opening, and a second end of the nozzle segment is connected with a first end of the main body segment, and a second end of the main body segment is connected with the first end of the tail segment;
- the nozzle segment and the main body segment are formed integrally;
- internal cavities of the nozzle segment and the main body segment together constitute the storage cavity, and an opening at the first end of the nozzle segment is the discharge port;
- the piston is provided in the main body segment, and the piston and the main body segment form an interference fit;
- the piston electric driving device is connected with the tail segment, and is used for driving the piston to move a distance towards the nozzle segment and then stop moving,
- wherein, a surface of the piston facing away from the nozzle segment forms a part of a wall surface of an airtight chamber;
- the piston electric comprises a pressurization device, a pressure relief device and a control device;
- the pressurization device is used for increasing pressure in the airtight chamber, and the pressure relief device is used for releasing the pressure in the airtight chamber, and the control device is used for controlling opening and closing of the pressurization device and the pressure relief device;
- when the control device is in a first working state, the pressure relief device is closed and the pressurization device is opened;
- when the control device is in a second working state, the pressure relief device is opened and the pressurization device is closed, and
- wherein, the control device mainly comprises a power supply unit and a control unit, which are connected with each other;
- the power supply unit is an electric source or a battery, and the control unit is connected with the pressurization device and the pressure relief device;
- the control unit is used for controlling a connection state of the power supply unit with the pressurization device and the pressure relief device, and the connection state is connected or disconnected;
- the control unit comprises an induction disk, an integrated circuit (IC2) and a field effect transistor (Q1);
- when the induction disk receives induction, the integrated circuit (IC2) and the field effect transistor (Q1) are controlled to connect the power supply unit with the pressurization device and the pressure relief device, so as to control to open the pressurization device and close the pressure relief device;
- when the induction disk does not receive the induction, the integrated circuit (IC2) and the field effect transistor (Q1) are controlled to disconnect the power supply unit with the pressurization device and the pressure relief device, so as to control to close the pressurization device and open the pressure relief device.
