[0002] As a common household item in people's daily lives, a hot water kettle has the functions of both pumping and boiling water and is easy to use. The hot water kettle includes a mounting base, a water storage kettle body mounted on the mounting base, a water pump mounted in the mounting base, a water inlet pipe connected to the water inlet connector of the water pump, and a water outlet pipe connected to the water outlet connector of the water pump. Among them, most hot water kettles with water pumps currently choose to set the water outlet pipe at the bottom of the water pump. With regard to the related technology mentioned above, the inventor believes that after the water pump of the above-mentioned hot water kettle is started, there is a probability that a certain amount of air will remain above the water pump assembly due to the water being not full, resulting in the vacuum of the water pump being destroyed, thereby affecting the water output. Utility Model Content

[0003] In order to improve the problem that air may exist on the top of the pump head and affect the water discharge from the kettle when the water pump works for the first time, the present application provides a kettle with a water pump assembly.

[0004] The present application provides a kettle with a water pump assembly adopting the following technical solution:

[0005] A hot water kettle with a water pump assembly comprises a kettle stand, a kettle body mounted on the kettle stand, a water outlet pipe arranged on the kettle stand, and a water pump for pumping water in the kettle body into the water outlet pipe; the bottom of the kettle body is provided with a water supply pipe connected to the inner cavity of the kettle body; the water pump has a pump head and a water pump motor; the pump head has a water inlet joint connected to the water supply pipe and a water outlet joint for connecting to the water outlet pipe, and the water outlet joint is arranged at the top of the pump head.

[0006] By adopting the above technical solution, water in the inner cavity of the kettle body can be input into the water pump through the water supply pipe and the water inlet joint of the pump head, and then output to the water outlet pipe through the water outlet joint arranged at the top of the pump head, thereby achieving the pumping out of the inner cavity of the kettle body. In particular, the arrangement of the water outlet joint at the pump head makes it difficult for air to be trapped at the top of the pump head during the first operation of the water pump, thereby reducing the probability of the water pump generating abnormal noise and malfunctioning during the first operation.

[0007] Optionally, the kettle holder includes a base and a water outlet rack installed on one side of the base; the water pump is arranged in the inner cavity of the base, the pump head has a mounting top plate, and the mounting top plate is fixed to the top wall of the inner cavity of the base by screws.

[0008] By adopting the above technical solution, the structure of the kettle rack is disclosed, and the water pump is fixed to the top wall of the inner cavity of the base by installing the top plate, which helps to arrange the space of the inner cavity of the base.

[0009] Optionally, the inner cavity top wall of the base has a mounting groove for arranging the mounting top plate, and the inner cavity top wall of the base is provided with a limiting protrusion in the mounting groove to limit the movement of the mounting top plate.
