The present application discloses an electric toothbrush, which relates to the technical field of toiletries, and specifically comprises a body and a toothbrush head, wherein two through holes are integrally formed at an end of an end cover at the front of the body, and two groups of lamp beads are installed on the inner side of the end cover near the top through the lamp control circuit board. The toothbrush head is composed of a sleeve, a central main rod and a vibrator docking unit as a whole, wherein the central main rod and the vibrator docking unit are all made of PMMA high light-transmitting plastic by integral injection molding. The present application improves the design on the basic structure of the existing split-type electric toothbrush, so that it can realize the disinfection and sterilization of each dead corner of the toothbrush head.

An electric toothbrush replacement head is provided and includes a replacement head handle; an opening disposed on an end of the replacement head handle; a transmission connecting part disposed in the opening; at least one through-groove disposed on an edge of the transmission connecting part; a transmission directional elongated groove disposed in the transmission connecting part; reinforced ribs disposed between the transmission connecting part and a portion where the replacement head handle is provided with the opening. The electric toothbrush replacement head with a reasonable structure is easy to replace and stable for using. Furthermore, the electric toothbrush replacement head is convenient, safe and reliable, which can also eliminate motor noise.

A vehicle washing system includes a vehicle treatment area that is configured to receive a vehicle to be dried. At least one dryer media device is positioned in the vehicle treatment area. The at least one dryer media device is configured to dry the vehicle upon contact with the vehicle. An air moving assembly is located adjacent to the at least one dryer media device in the vehicle treatment area, and is configured to remove excess moisture from the at least one dryer media device.

A software-implemented process for preventing reuse of a replaceable cleansing attachment includes detecting, via a chip in the replaceable cleansing attachment, that the replaceable cleansing attachment is attached to a base. The method also includes during a first use, receiving, at an acoustic transducer, high-frequency current from the base, wherein the acoustic transducer converts the high-frequency current into sound waves to assist in an abrasive removal of wound coatings. And the method includes recording, to the chip, an indication of the first use of the replaceable cleansing attachment, wherein the chip is configured to prevent a second use of the replaceable cleansing attachment when the chip has the indication of first use of the replaceable cleansing attachment stored thereon.

The invention relates to a skin treatment device comprising a housing (10) with a handle section (11), a disc-shaped skin treatment element (21), a drive mechanism incorporated in said housing and coupled to said skin treatment element for driving said skin treatment element into rotational movement about a rotational axis, wherein said skin treatment element has a first skin treatment surface (22) and a second skin treatment surface (25), said first skin treatment surface (22) being oriented axially with respect to said rotational axis, said second skin treatment surface (25) being oriented radially with respect to said rotational axis and extending along a circumference of the skin treatment element.

An electric toothbrushing device is disclosed, the device comprising means (16) for producing vibration of a toothbrush head (14), means (24, 32, 40, 42, 44) for producing an orientation signal indicating of an area of the mouth being brushed, and means (47, 48, 49) for producing a pressure signal indicating a pressure applied to the toothbrush head. The device further comprises processing means (46) arranged to link values of the orientation signal with values of the pressure signal in order to provide feedback to a user regarding a brushing pressure applied to each of a plurality of different areas of the mouth. By linking values of the orientation signal with values of the pressure signal, the user can be better informed about which parts of the mouth are being or have been brushed too hard. This can help the user to correct their brushing technique.
