Miniature temperature control pressurizing pump

The invention provides a miniature temperature control pressurizing pump and relates to a pressurizing pump. The miniature temperature control pressurizing pump achieves pressurization through heating steam control temperature, does not need a complicated mechanical device, does not need to be driven by a motor and an impeller, is small in volume and simple and compact in structure, and can pressurize to 4-5 pa theoretically. The miniature temperature control pressurizing pump comprises a liquid inlet chamber, a liquid storage chamber, an air chamber, an air pressure sensor and a heating device. An outlet of the liquid inlet chamber is connected with an outlet of the liquid storage chamber through a one-way channel, a one-way valve is arranged on the one-way channel, a heat insulation film is arranged between the top of the liquid storage chamber and the air chamber, a pressure release valve is arranged at the top of the air chamber, the air pressure sensor is arranged on the air chamber, a heat insulation layer is arranged on the inner wall of the air chamber, volatile liquid is arranged at the bottom of the air chamber, the heating device is arranged below the bottom of the air chamber, a liquid outlet is arranged at the bottom of the liquid storage chamber, and an electromagnetic valve is arranged on the liquid outlet.
