A cover structure of a washer pump has a base and a cover. The base and the cover are removably assembled together, which improves effect of the spa machine.

An inflatable spa is disclosed having improved strength. A water cavity of the inflatable spa may receive massaging air bubbles and/or jetted water.

A nano-bubble water generating apparatus containing an application gas includes a motor, a pump integrated with the motor for supplying liquid, typically water, from an inlet pipe under a predetermined pressure through a supplying pipe to a pressure tank, a nano-bubble water generating tube mounted at the water entrance of a pressure tank, an electronic control portion, a pressure adjuster including an outer air inflowing portion to introduce an outer air or a specific gas supplied thereinto to control a pressure in the pressure tank, uniformly and a pressure adjusting portion airtightly coupled on the upper portion of the outer air inflowing portion to adjust an amount of outer air or specific gas to be supplied, and a nano-bubble water expanding tube for expanding and shattering nano-bubble water through an outlet pipe from the pressure tank, so that the size of the nano-bubble water is better micronized.

An improved mount is of the type used in a foot spa. The foot spa is of the type having a surface which defines a vessel for containing water and a pump magnetically driven by rotating magnets. The mount defines part of the surface and holds the pump against rotation. The improvement comprises: a coil associated with the mount and disposed exteriorly of the surface of the basin and interiorly of the magnetic field produced by the rotating magnets to produce a current; a plurality of lights operatively connected to the coil; and light conductivity associated with the mount to permit the light to be visible interiorly of the basin.

A whirlpool foot bath for a pedicure chair having a housing with a removable cap and a rotor and stator magnetic motor within the housing. Water in the bath is circulated through an inlet in the cap and out through at least one outlet in the cap. A method of use is described.

An apparatus including a motor assembly having a motor. A jet assembly coupled to the motor assembly having an inlet and outlet aperture. An impeller configured to rotate causing a first fluid to flow into the inlet aperture and out the outlet aperture. A fluid guider that includes at least one wall member defining a first channel configured to guide the first fluid from the inlet aperture into the cavity. Additionally, the fluid guider includes at least one post defining a second channel extending through the post. The second channel configured to guide the first fluid from the cavity towards the outlet aperture and output the first fluid at an oblique angle with respect to a longitudinal axis of the post. A second fluid channel member configured to provide a second fluid out the outlet aperture. A light source configured to illuminate the first fluid.

A bathwater circulating system has a pump operable to draw fluid in at an intake port and expel it under pressure at an output port. Water- and air-supply conduits feed water and air to the intake port at a rate determined by a flow-restricting air-intake valve so that the pump mixes the water and the air, pressurizes the mixture and thereby dissolves the air in the water, and expels the air/water mixture at the output port. A pressure-reducing valve is connected by an output conduit that extends from the output port to the pressure relief valve and conducts the water/air-bubble mixture from the pump to the pressure-reducing valve without separation of the air from the water and such that the mixture is at least partially depressurized at the pressure-reducing valve such that the air forms microbubbles in the water.
