A retractable interdental brush includes an interdental brush, a retractable mechanism, and a handle. The retractable mechanism is configured to drive the interdental brush to extend from the handle to clean a gap between teeth. After use, the interdental brush is retracted into an accommodation space of the handle through the retractable mechanism. The interdental brush may be a built-in interdental brush. When the built-in interdental brush is used for cleaning, a brush body may be first retracted into an elbow at a front end of a delivery device, an outlet of the elbow is pressed against the gap between teeth to push the brush body, and a working portion of the brush body and enters into the gap between teeth to clean the gap between teeth, thereby resolving a problem with existing interdental brush that easily stabs gingival tissue due to a difficulty of alignment with the gap between teeth.

The present invention offers a halo-illuminating light pattern for clearly showing areas of a pet's fur to the user performing brushing. Such a halo-illuminating light pattern provides a full, 360-degree light pattern of the pet's fur. This eliminates the necessity for using an additional light source, for example a flashlight or being made to settle on a light source that only highlights one side of a pet's fur, leaving another side in shadow.

A mist spraying hair brush with retractable bristles includes a brush body, an actuating shaft, a mist spraying assembly, and a housing containing these components. The actuating shaft has a bended portion. When the actuating shaft is rotated and the bended portion pushes the brush body, multiple bristles of the brush body extend out of the housing. The mist spraying assembly has an electric oscillation assembly and an injection portion. The injection portion communicates with the oscillation assembly, such that liquid flows to the oscillation assembly via the injection portion and is atomized into spray. Then the spray flows out of the housing. The mist spraying hair brush with retractable bristles is small in size and is convenient in storage. Moreover, the multiple bristles can retract into the housing, so the multiple bristles will not be bended when carried in a bag full of objects.

A cosmetic article including a case and a applicator that is fastened to the case but movable relative to the case between a retracted position and an extended position, in which the applicator extends outward from the case further than in the retracted position. The applicator includes a body and protuberances, at least some of which are arranged so as to be movable relative to the body between a retracted position and an extended position, in which the protuberances extend outward from the body further than in the retracted position.

Controllable brush, comprising a bristle carrier (BC) having a plurality of bristles (B), and a supplementary carrier (SC) having a plurality of protrusions (P), a distance (d) between the supplementary carrier (SC) and the bristle carrier (BC) being modifiable, whereby decreasing the distance (d) results in the protrusions (P) being inserted through the bristle carrier (BC). Decreasing the distance (d) results in the protrusions (P) being inserted inside the bristles (B). Alternatively, decreasing the distance (d) results in the protrusions (P) being inserted between the bristles (B). The controllable brush may further comprise an actuator for modifying the distance (d), and a control unit for controlling the actuator in response to a sensor output. The sensor may be arranged for measuring a force experienced by the brush. Alternatively, the sensor may be a camera of a smartphone.

A computer-implemented method of training a user to effectively apply makeup using a computerized makeup brush, the method comprising the steps of receiving, from a makeup brush movement tracking system that comprises one or more sensors for sensing the movement of the makeup brush relative to a particular portion of a user's body, data representing a movement of the makeup brush relative to the particular portion of the user's body over a particular period of time as the makeup brush is used to apply makeup to the particular portion of the user's body, and using the data to generate and communicate, to a user, information regarding the movement of the makeup brush over the particular period of time.

A brush includes a housing and a brush head. The brush head is slidably engaged with the housing to vary a bristle density of the brush head.

A make-up brush system includes a mandrel having a first end and a second end. The first end includes a gripping surface for engagement with a hand of a make-up artist and the second end being shaped and dimensioned for selective engagement with a plurality of make-up brushes. A plurality of make-up brushes is provided. Each of the plurality of make-up brushes includes a first end and a second end, the first end including a functional component of the make-up brush and the second end including a coupling member shaped and dimensioned for selective engagement with the second end of the mandrel. The system also includes a case both supporting and sanitizing the various components of the present invention. The case includes a tray supporting the plurality of make-up brushes in accessible positions within the case.

The present invention relates to a brush head (10, 10a, 10b, 10c) for use with a body care device (100), comprising a plurality of bristles (22, 22a-22e), a carrier (16) for fixedly carrying the plurality of bristles (22, 22a-22e), and connection means for connecting the carrier (16) to a housing (50) of the body care device (100) defining a first axis (14), so that, when the brush head is connected to the housing (50), the carrier (16) is rotatable about the first axis (14) and pivotable about a second axis (20) perpendicular to the first axis (14) with respect to the housing (50), wherein the carrier (16) comprises a plurality of carrier parts (17), each fixedly carrying a corresponding one of a plurality of bristle groups (26, 28, 30), and wherein at least one of the plurality of carrier parts (17) comprises a shaft defining a third axis (40, 42, 44) about which the corresponding bristle group (26, 28, 30) is rotatable.

An interdental brush (1) comprises a body (4) with a handle (5) and a guide channel (7). Also provided is a connecting element (9), which connects a cleaning body (3) to an operating element (6). The connecting element (9) with the cleaning body (3) can be displaced in a reciprocating manner within the guide channel (7), by means of the operating element (6), between a retracted position, in which the cleaning body (3) is arranged within the guide channel (7), and an extended position, in which the cleaning body (3) projects out of the guide channel (7) at a distal end of the guide channel (7), as seen in relation to the handle (5). A flexible positioning element (2) is provided at the distal end of the guide channel (7). The positioning element (2) can be placed in an approximal space between two teeth such that the cleaning body (3), during displacement into the extended position, penetrates into the approximal space. The reciprocating displacement of the cleaning body (3) can be induced by movement of the operating element (6) relative to the positioning element (2) of the interdental brush (1).
