Abstract

A heating and cooling cup includes a cup body, a stirring device, a heating and cooling chip, and a heat sink module. A heat conductive block is disposed under the cup body, the heat conductive block abuts against the heating and cooling chip, the stirring device has a stirring rod disposed in the cup body, and a bottom surface of the heating and cooling chip abuts against a heat conductive block of the heat sink module. A temperature of the cup body is changed through the heating and cooling chip, for cooling or heating liquid food in the cup body, and the liquid food is forced to generate convection through the stirring rod for accelerating a temperature variation process.

Claims

1. A heating and cooling cup, at least comprising:

a cup body, wherein a heat conductive block is disposed under the cup body in a protruding manner, a power jack is disposed on one side of the cup body, a base is disposed under the cup body, and the heat conductive block is inserted in the base;

a stirring device, disposed under the cup body, and having a motor and a stirring rod, wherein the stirring rod is power-connected to a driving shaft of the motor, the stirring rod is located in the cup body, and the motor of the stirring device is electrically connected to the power jack;

a heating and cooling chip, disposed under the stirring device, wherein one surface abutting against the heat conductive block of the cup body is a contact surface, and the other side is a heat dissipation surface, the heating and cooling chip conducts the heat out of or into the cup body through the heat conductive block of the cup body, and the heating and cooling chip is electrically connected to the power jack; and

a heat sink module, disposed under the heating and cooling chip, having a heat conductive block, a heat sink fin, and a heat sink fan, wherein an upper part of the heat conductive block abuts against the heat dissipation surface of the heating and cooling chip, the heat sink fin wraps the heat conductive block, the heat sink fan is disposed under the heat sink fin, and the heat sink fan is electrically connected to the power jack.

2. The heating and cooling cup according to claim 1, wherein the cup body has an inner tank disposed therein, and the inner tank is made of a heat insulating material.

3. The heating and cooling cup according to claim 1, wherein the power jack of the cup body establishes electrical conduction with a power source.

4. The heating and cooling cup according to claim 1, wherein the stirring rod has a plurality of stirring blades.

5. The heating and cooling cup according to claim 1, wherein the stirring rod is replaced by a stirring disc.

6. The heating and cooling cup according to claim 1, wherein the heat sink fan of the heat sink module is wrapped in a filter.
