A hair coloring appliance includes a handle and a hair color delivery system supported within the handle. A nozzle assembly is adapted to receive hair color. The nozzle assembly includes a stationary frame and a nozzle array through which the hair color is delivered to the hair and a plurality of filaments adjacent the nozzles which are longer than the nozzles, acting as a stand-off between the nozzles and the scalp. A motor reciprocates the nozzle array back and forth as hair color moves through the nozzles.

A system for coloring hair, the system including at least one cartridge containing a hair color, a hair color device comprising one or more chambers configured to receive the at least one cartridge, and a processor communicatively coupled to the dispense, wherein the process or is configured to visualize an image of a user's hair, detect one or more hairs in a predetermined color range in the image through image processing, and apply the hair color onto the one or more hairs in a predetermined color range through an applicator on the hair color device.

A dry-cleaning brush includes a body, a base plate and a bristle component. A storage cavity used for storing shampoo powder is formed between the body and the base plate. A powdering device is arranged in the storage cavity and includes a pressing rod arranged on the base plate, lever assemblies, pistons, and at least one leaking hole formed in the base plate, and the pistons are located at openings of the leaking holes. Each lever assembly includes a lever having two ends respectively clamped on the pressing rod and the corresponding piston. A rebound mechanism is arranged between an elastic gland, the pressing rod and the base plate. The powdering device controls the pistons based on the lever principle, the elastic gland and the pressing rod are pressed to drive the levers to pull the pistons away from the leaking holes.

A formula delivery appliance generally includes a formula delivery head having features to mix, direct, and distribute formulation through nozzles to a desired location, such as the hair or scalp of a user. In this regard, the formula delivery head may include a plurality of nozzles configured to discharge the formulation at a desired flow rate. In some instances, the flow rate across the plurality of nozzles is controlled such that each nozzle has a flow rate within a specified percentage of the average flow rate across the plurality of nozzles.

Formulation delivery systems, formulation delivery devices, and formulation cartridges for the same are provided. Formulation delivery systems include a reusable handle, a formulation dispensing assembly, and a controller. The formulation dispensing assembly includes a reciprocating nozzle assembly and a pump. The reciprocating nozzle assembly is fluidically-coupleable to the formulation cartridge or the cleaning cartridge received within the reusable handle. Formulation delivery devices include a reusable handle configured to receive a formulation cartridge therein, and a formulation dispensing assembly disposed in the reusable handle. The formulation dispensing assembly includes fluid conduits, a pump fluidically connected to the fluid conduits, a reciprocating nozzle assembly, and a controller. Formulation cartridges include a reusable cartridge body, a valve frame, and a disposable refill packet reversibly-coupleable to the reusable cartridge body. The disposable refill packet includes a formulation packet and a body portion configured for insertion into the reusable cartridge body.
