Abstract

A foot tub capable of generating a bubble in use includes a base and a tub wall connected to the base, where the base and the tub wall enclose a tub chamber; an impeller is provided in the tub chamber above the base; the impeller is covered by a protective guard; a hollowed-out opening is formed in the protective guard; the protective guard further communicates with an outside atmosphere through a vent tube; a drive motor is provided in the base, and the drive motor is drivingly connected to the impeller, such that the drive motor can drive the impeller to rotate; and in response to rotation of the impeller, while water is thrown out of the protective guard through the hollowed-out opening, a local low pressure is further formed in the protective guard, such that outside air can enter the protective guard through the vent tube.

Dependent claims

A foot tub capable of generating a bubble in use, comprising a base and a tub wall connected to the base, wherein the base and the tub wall enclose a tub chamber;

an impeller is provided in the tub chamber above the base;
the impeller is covered by a protective guard;
a hollowed-out opening is formed in the protective guard;
and the protective guard further communicates with an outside atmosphere through a vent tube;
a drive motor is provided in the base, and the drive motor is drivingly connected to the impeller, such that the drive motor drives the impeller to rotate;
in response to rotation of the impeller, while water is thrown out of the protective guard through the hollowed-out opening, a local low pressure is formed in the protective guard, such that outside air enters the protective guard through the vent tube, and the water thrown out by the impeller in the rotation is mixed with the air to generate a bubble;
wherein an upper end of the tub wall is provided with a cover plate, and the vent tube is provided between the cover plate and the protective guard;
a driving connection manner between the drive motor and the impeller is as follows:
an output end of the drive motor is provided with a drive plate;
a driving magnet is provided on the drive plate;
a driven magnet is provided on the impeller;
and the driving magnet is opposite to the driven magnet through unlike poles, such that the drive plate in rotation drives the impeller through a magnetic attraction force to rotate;
and
a rotating shaft is provided on the impeller;
the rotating shaft is inserted into the base;
and the impeller rotates with the rotating shaft as an axis.
