The present invention relates to a toothbrush comprising a head portion comprising a cleaning formation for cleaning teeth in use. A handle portion is connected to the head portion. The toothbrush comprises a musical wind instrument, the wind instrument comprising a resonant cavity extending within one or both of the head portion and the handle portion, and an air inlet operatively connected to the cavity and configured to induce resonance with the cavity by exhalation from the user in use.

An interdental cleaning tool (1) comprises a base (10) having a shaft (20) that has a shape to be inserted into an interdental space, wherein the base (10) is formed of a composite material comprising a synthetic resin, a reinforcement material and a low-hardness resin having a lower hardness than the hardness of the synthetic resin.

This disclosure relates to oral care mouthpieces and methods of forming oral care mouthpieces. A disclosed oral care mouthpiece includes a base shaped to a dental arch. The base elastically deforms in response to pressure variations in the mouthpiece, The mouthpiece also includes a set of one or more supports attached to the base and placed to allow the base to elastically deform in response to the pressure variations in the mouthpiece. The mouthpiece also includes a set of oral care elements attached to the set of one or more supports and placed to transmit pressure to the dental arch when the base elastically deforms in response to the pressure variations in the mouthpiece.

The disclosure provides a hair brush, comprising a body, a comb teeth assembly and an active static electricity elimination device; the body is provided with a hollow cavity; the comb teeth assembly comprises a plurality of comb teeth which is provided on the body; the active static electricity elimination device is set in the hollow cavity; the active static electricity elimination device comprises a static electricity processing device and a plurality of additional function devices; the input end of the static electricity processing device is electrically connected with the comb teeth assembly, the output end of the static electricity processing device is electrically connected with at least one of the pluralities of additional function devices, and the static electricity processing device processes the static electricity input by the comb teeth assembly and outputs the static electricity to the additional function devices, which consumes electric energy of the processed static electricity.

There is provided an electric toothbrush including a toothbrush head, a toothbrush handle and a force sensing array. The force sensing array is arranged on the toothbrush head and/or the toothbrush handle. When the force sensing array is arranged on the toothbrush head, it is able to detect the force uniformity of brush hairs. When the force sensing array is arranged on the toothbrush handle, it is able to control the vibration strength of the brush hairs and detect the pressing force of the brush hairs.

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.

A method for oral care. In one aspect, the method for oral care includes a) receiving sensor data from at least one sensor configured to detect motion of an oral care device during a brushing routine of a user, the sensor data corresponding to the detected motion; and b) determining a target brushing time based on the sensor data. In another aspect, the method for oral care includes a) receiving sensor data from at least one sensor configured to detect brushing intensity during a brushing routine of a user, the sensor data corresponding to the detected brushing intensity; and b) determining a target brushing time based on the sensor data.

There is provided a controller for a fluid-detection system, wherein the controller is configured to: determine if a user is interacting with the fluid detection system, wherein the determining comprises at least one of: determining whether a user is within a predetermined distance of the fluid detection system; determining whether a user is in physical contact with the fluid detection system; determining whether a fluid sensor of the fluid detection system is in a mouth of a user; and control the temperature of the fluid sensor of the fluid detection system based on the result of the determination. There is also provided a fluid based detection system comprising the controller, a device comprising the controller, a remote device comprising the controller, and a computer implemented method for controlling a fluid detection system, the method comprising the steps of: determining if a user is interacting with the fluid detection system, wherein the determining comprises at least one of: determining whether a user is within a predetermined distance of the system; determining whether a user is in physical contact with the fluid detection system; determining whether a fluid sensor of the fluid detection system is in a mouth of a user; and controlling the temperature of the fluid sensor of the fluid detection system based on the result of the determination.

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.

Improved folding broom-cleaning-storage apparatus for cleaning are provided. The folding broom-cleaning-storage apparatus comprises components to form a variety of broom configurations. The apparatus comprises folding components which may be assembled and disassembled quickly and simply. The apparatus comprises a case which may be used as a separate dustpan, and which may be connected to the broom configurations for use, and which may store the broom components when the broom components are disassembled. The apparatus may comprise shaped bristles, which may be arranged in layers, and offer improvements in efficiency when used.
