Systems and methods for mixing an oral care formulation base with one or more oral care additives in-situ. In one aspect, the invention can be a method of making an oral care formulation for consumer use, the method comprising: a) providing a first dose of an oral care formulation base to an oral cavity of a test subject; b) dispensing one or more oral care additives to the oral cavity in accordance with a first dispensing regimen during the performance of step a), the one or more oral care additives mixing with the first dose of the oral care formulation base in-situ within the oral cavity of the test subject; c) obtaining feedback regarding effects experienced by the test subject during the performance of step b); and d) creating the oral care formulation for consumer use based, at least in part, on the feedback of step c).

The present invention relates to a shower hose cleaner having a new structure that can easily clean a shower hose connected to a shower head. The shower hose cleaner according to the present invention is configured to comprise a case 10 having a tubular shape extending in a longitudinal direction and a brush member 20 provided on an inner circumferential surface of the case 10, and the case 10 is configured to be able to be divided into two parts. When the case 10 is coupled to an outside of the shower hose 2 and slid in the longitudinal direction of the shower hose 2, an outer circumferential surface of the shower hose 2 is cleaned by the brush member 20, and the shower hose 2 can be easily cleaned.

A solar panel cleaning system includes a brush connected by a hose to a fluid supply. The brush has scrubbing material, such as bristles, attached to a brush body for mechanically cleaning the surface of the solar panel. The width of the contact surface of the scrubbing material may be equal to the width of the solar panel, so that the solar panel may be cleaned with only upward and downward strokes. The brush body may further support a fluid manifold that receives the fluid from the fluid supply. The fluid manifold may include nozzles that emit the fluid under pressure onto the solar panel. The nozzles may project both frontward and rearward of the brush body so that the fluid sprays off the solar panel in front of and behind the brush. Spray patterns of the nozzles may overlap and impinge the entire width of the solar panel.

A toothbrush is provided. The toothbrush may include a brush head having a first brush and a second brush. Each of the first brush and second brush may include bristles extending radially from first ends of the first brush and second brush. The first brush and second brush may rotate in opposite directions along rotational axes parallel to a longitudinal axis of the toothbrush to brush away from the gums of a user and assist with implementing a rolling brushing method.

A cleaning mechanism having a self-locking function, comprising a cleaning rack, a cleaning member and a sweeping member, adapted for use on photovoltaic panel, is disclosed. The cleaning rack comprising a first connecting rod, a second connecting rod, a third connecting rod and a fourth connecting rod which are detachably connected. The cleaning member being detachably mounted between the first connecting rod and the third connecting rod, used for stripping off adhesive materials on photovoltaic panel; the sweeping member used for sweeping adhesive materials away from photovoltaic panel. Cleaning mechanism further comprises a cleaning member power unit, detachably connected with the cleaning member and used for driving cleaning member to rotate; and cleaning member power unit comprises a self-locking device, used for preventing cleaning member from idling, and sundries are prevented from being twisted thereon and meanwhile unnecessary wear between cleaning member and photovoltaic panel can be reduced.

The present disclosure relates to a device for cleaning and polishing connections of underwater equipment, comprising a connecting element designed to be connected to a torque generating device; a cleaning fluid discharging device comprising at least one tank of cleaning fluid; and a cleaning element connected to the discharging device via a support for the cleaning element, wherein the support for the cleaning element comprises at least one channel that connects the at least one tank of cleaning fluid to the cleaning element, wherein the cleaning fluid discharging device comprises a piston, which, in its turn, comprises: at least one tank of cleaning fluid; and at least one actuating chamber, wherein at least the actuating chamber comprises a pressure compensating system.

A dispensing paintbrush includes a handle, a brush head connected to the handle, and bristles attached to the brush head to apply a fluid to a surface. A coupler is attached to the handle and is configured to connect to a fluid source. A nozzle is attached to the coupler and is configured to dispense the fluid to the bristles. The nozzle extends within the bristles and terminates at a position from the brush head that is less than one half the length of the bristles.

An oral cleansing device including a base and a tip holder configured to hold a tip for the oral cleansing device, such as a brush head, a jet tip, or a combination tip. The tip holder may be removably coupled to the base.

An oral cleansing device including a handle, a brush head removably connected to the handle at a top end of the handle, a base unit that supports a reservoir to serve as a fluid source, a fluid tube extending from the base unit, and a fluid connector connected to the fluid tube and removably connected to the handle at a bottom end of the hand to connect the handle to the fluid source. The fluid connector includes a magnetic element configured to provide a magnetic attraction to the base unit, thereby assisting in securing the fluid connector to the base unit.

An attachment for use with a hose. The attachment includes a body having a proximal end opposite a distal end. The body defines an inlet disposed at the proximal end. The body further defines an outlet at the distal end. The body defines an inner flow passage operable to enable water to flow from the inlet to the outlet. A connector is disposed at the proximal end of the body and is operable for attachment to a water source. A plurality of bristles is disposed at the distal end of the body and is operable for scrubbing a surface.
