In some embodiments, an authorization server device receives a request for an activation token to activate a personal care device. The authorization server device determines an authorized usage amount, and generates an activation token based on the authorized usage amount to be transmitted to the personal care device. Activation of a personal care device may be authorized based on consumable products obtained for use with the personal care device. By limiting activation of the personal care device based on consumable products obtained for use with the personal care device, the technical problems in overuse of some consumable products (such as brush heads) or underuse of other consumable products (such as serums or cleansers) can be avoided, and maximum results from use of the personal care devices can be easier to obtain.

An oral care implement including a handle and an oral care refill head. The handle has a gripping portion, an engagement component coupled to a distal end of the gripping portion, and a stem. The engagement component includes a plate portion and a first engagement feature. The stem extends through an opening in the engagement component and protrudes from the plate portion. The oral care refill head includes an oral care treatment portion and a sleeve portion. The sleeve portion has an inner surface that defines a sleeve cavity having a cavity axis and a second engagement feature. When the oral care refill head is detachably coupled to the handle, the first and second engagement features mate with one another to at least one of: (1) position the oral care refill head and the handle in an operational alignment; and (2) lock the oral care refill head to the handle.

According to an exemplary embodiment, a toothbrush having one or two heads for use in a variety of humans and animals may be shown and described. The toothbrush can have offset heads and bristle areas, include multiple curves of (a) neck/head portion(s) to provide improved access and cleaning ability, and may be separable or combined with other toothbrush elements or components.

An automated building washing device generally includes one or more rotational brushes having a vertical rotational axis coupled to a window washing swing stage. The brushes are horizontally movable from end-to-end along the longitudinal direction of a window washing swing stage while rotating about their vertical axis so that a relatively large portion of building surface can be quickly cleaned.

A toothbrush, including a head portion, a handle portion, a locking mechanism configured to lock said head portion to said handle portion, a capsule including a motor assembly and power supply, the capsule being configured to be received within said handle portion, and at least one communication connection configured to enable said toothbrush to communicate with one or more external computing devices.

The group of inventions can be used for removing deposits B sewers and their simultaneous removal of various pipelines and cleaning process provides mechanization and sewage pipe work, eliminate the need for disassembly of the drain system and manual cleaning. With actuator mounted outside sewer pipe, is moved along the sewer c associated drive the movable member and fixed therein Ha cleaning tool arranged within the sewer pipe. In the initial position will cleaning tool located at the end of the sewer pipe portion is sewer piping connecting the drain pipe to the riser. Upon reaching the final cleaning tool in the positions of the junction of the sewer with the riser and c by the drive of the movable member is moved scraping tool to its original position.

A toothbrush with suctioning and cleaning functions according to an embodiment of the present invention includes a toothbrush rod including a head portion and a handle portion, a brush disposed at the head portion, a through-hole portion formed at the head portion to supply cleaning water to an oral cavity or suction in dirty water from the oral cavity, a guide tube disposed within the toothbrush rod and connected to the through-hole portion to deliver the cleaning water to the through-hole portion or deliver the dirty water suctioned in through the through-hole portion to the outside, and an external main body to supply the cleaning water to the guide tube and to receive the dirty water from the guide tube.

The present invention comprises systems and methods for using a specialized styling device, such as a smart hairbrush, smart comb, or accessories, which allow for the collection of data from the devices, and for users to interact over a wireless network. The devices may including a wireless radio frequency modem connected to the internet and a battery to power components, including lights, speakers, cameras, microphones, and sensors. A smart brush may allow for computations through processors, memory, system-on-a-chip, applications, batteries, operating systems, and wired or wireless communication interfaces. It is also possible for the smart brush to connect with other electronic devices, including phones, tablets, and cameras in order to share electrical power and communicate over one or more interfaces. A smart brush may operate as an independent mobile device or within a smart home or other system with multiple computing devices, appliances, and sensors connected together within a network.

A vehicle washing system includes a frame disposed above a vehicle treatment area, and a reciprocal guide system coupled to the frame. The guide system is configured to move vertically relative to the frame, and supports a vehicle treatment component such as a rotatable brush. The brush may be lowered and raised relative to the vehicle treatment area by extending or retracting the guide track. When the guide system is retracted upward, there are no downwardly extending guides or rails that extend downward from the bottom of the guide system. The guide system is collapsible in a vertical direction, and may be a scissors mechanism or a telescoping mechanism or other collapsible mechanism. The guide system may be actuated directly or may be actuated dependent on a separate vertical drive mechanism, such as a windable belt.

A vehicle wash system includes a frame suspended above a vehicle treatment area. A pivotable frame is pivotally coupled to the frame, and an extendable and retractable linear frame is coupled to the pivotable frame and configured to extend downward from the pivotable frame and retract upward toward the pivotable frame. A top brush is coupled to a lower end of the linearly frame, and is extendable toward engagement with a vehicle. The top brush is also pivotable relative to a vertical position via pivoting of the pivotable frame, and the top brush is pivotable at different degrees of extension of the linear frame. The linear frame and the top brush may pivot in response to contact from the vehicle.
