In addition, the electronic devices and insulating glue in the base of the electric kettle will be in a high-temperature environment during work, and are easily damaged after long-term use. Therefore, the market has launched an electric kettle with ventilation and heat dissipation functions.

[0003] For example, the Chinese utility model patent with publication number CN205795505U discloses an electric kettle and its base, which includes a hollow shell and a heat dissipation fan. The shell includes a first end face, a second end face, and a side wall. The first end face and the second end face are oppositely arranged and are connected to the side wall to form a containing cavity. The heat dissipation fan is arranged in the containing cavity. An air inlet hole is formed in the side wall, and an air outlet hole is formed in the second end face. The heat dissipation fan drives air flow to achieve the effect of rapidly cooling hot water.

[0004] For example, the Chinese utility model patent CN213664825U discloses a fast heat dissipation electric kettle base, which includes a bottom plate. The bottom plate has a heat dissipation hole at the bottom. A fan frame is fixedly installed on the top of the bottom plate. An electric motor is fixedly installed inside the fan frame. A fan blade is fixedly connected to the output shaft of the electric motor through a shaft coupling. The electric motor drives the fan blade to expel heat from the base, reducing the temperature of the base.

[0005] The existing technology has the following problems. The heat dissipation hole is arranged on the side wall and exposed to the external environment, which is not aesthetically pleasing. Dust and debris can easily enter the heat dissipation hole, or water can splash into the heat dissipation hole, damaging the heating element. In addition, the arrangement of the electric motor and the fan increases the production cost. Therefore, the existing technology needs to be improved. UTILITY MODEL CONTENTS

[0009] The inner ring edge and the outer ring edge are provided with a ventilation groove, and the ventilation groove is provided with an air inlet hole at the top or side, which is connected with the inner cavity of the base and the external environment.

[0010] As a further improvement of the above technical solution, the top end of the inner ring edge and the outer ring edge is connected by a first end face, which is annular.

[0011] As a further improvement of the above technical solution, the first end face is provided with a stud, which is fixedly connected with the base, and the bottom of the first end face is provided with a reinforcing rib.

[0012] As a further improvement of the above technical solution, the bottom of the inner ring edge is provided with a second end face, which is provided with a mounting hole at the center, and the mounting hole is provided with a coupler.
