The present invention is concerned with a storage container for an electric oral-hygiene device having a charging unit for charging an electric oral-hygiene device disposed in the container and an electrical input connector for providing energy to the charging unit.
It is known that an electric oral-hygiene device storage container can be equipped with a charging unit and an electrical input connector for providing energy to the charging unit. Document US 2014/150189 A1 generally discusses such an electric oral-hygiene device storage container.
It is an object of the present disclosure to provide an electric oral-hygiene device storage container that is improved over the known containers or that provides at least an alternate realization of such a container.
In accordance with one aspect there is provided a storage container for an electric oral-hygiene device, comprising a first casing part, at least a second casing part, which first and second casing parts are mechanically coupled to allow for an open-container state in which the electric oral-hygiene device can be removed from the container and a closed-container state in which the electric oral-hygiene device is secured inside the container, wherein the container further has a charging unit for selectively charging the electric oral-hygiene device, an electrical input connector realized at an outer side of the first or second casing part for providing energy to the charging unit, and at least one electrical output connector realized at an outer side of the first or second casing part, wherein the charging unit is arranged for selectively providing the energy received at the electrical input connector via the electrical output connector to an external device.
In accordance with one aspect there is provided a kit comprising the storage container as described in the present disclosure and an energy supply unit having an electrical output connector that is connectable with the electrical input connector of the container, wherein the electrical output connector of the energy supply unit and the electrical input connector of the container are designed as non-standardized coupling partners.
The present disclosure will be further elucidated by a detailed description of example embodiments and with reference to figures.
In accordance with the present disclosure, a storage container (or simply “container) for an electric oral-hygiene device (or simply “device”) comprises at least one electrical output connector arranged on an outer side of the first or second part of the casing. This enables one to use the container not only for storing and charging the removable electric oral-hygiene device, but also for charging an external device, e.g., a smartphone, a tablet computer, a pocket lamp, a fitness tracker etc. This enablement enhances the versatility of the container. In addition, the container may be equipped to house further parts such as replacement heads for the electric oral-hygiene device, a dental floss reservoir etc. The container may in particular be conveniently used during travel.
During travel, while the electric oral-hygiene device is being charged, e.g., in a hotel room, an external device can also easily be connected with the electrical output connector of the container so that carrying along a further charging device for this external device can be dispensed with. It is to be understood that the term “electric oral-hygiene device” means complete devices, such as, e.g., an electric toothbrush, as well as handles of such devices, to which a replaceable head (or heads) can be attached. The electrical output connector may in particular be arranged as a standardized outlet (e.g., male or female connector or plug), e.g., as an USB or mini USB outlet or as a DC connector, e.g., 2.1 mm or 2.5 mm pin size. In some embodiments, the electrical output connector can be arranged as an inductive electrical output connector, e.g., the electrical output connector may then be designed as an inductive electrical energy transfer unit in accordance with the Qi standard—or the electrical output connector may be designed in accordance with the Energy Matters Alliance standard.
The container comprises a casing having a first casing part and a second casing part that are mechanically connected. The first and second casing parts can be connected, e.g., by at least one hinge. Alternatively or additionally, the first and second casing parts can be connected by at least one snap or other type of lock or fastening connection, so that the container can be brought into an open position, in which the electric oral-hygiene device can be disposed in the container or can be taken out of the container, and into a closed position, in which the electric oral-hygiene device is secured inside the container, e.g., during travel.
In some embodiments, at least one of the first or second casing parts comprises an inlay having a recess for at least accommodating the electric oral-hygiene device therein. The inlay may be arranged to be replaceable, e.g., for cleaning purposes or to adapt the container to differently shaped electric oral-hygiene device or devices (i.e., at least two different inlays can then be provided). The inlay may comprise further recesses for receiving other parts such as, e.g., a replacement head for use with the electric oral-hygiene device.
The container comprises an electrical input connector and a charging unit for selectively charging the electric oral-hygiene device. The charging unit may be arranged for enabling the charging function only in the closed state of the casing, but in some embodiments charging is also possible in the open state of the casing. While the electrical input connector may be arranged in any known or standardized manner (e.g., as a USB, mini USB or DC connector), the electrical input connector can in some embodiments be arranged as a non-standardized and/or proprietary connection. In the latter instance, the electrical input connector can be configured to be coupled only with a respective non-standardized and/or proprietary (complementary) coupling partner, so that only a defined connection, such as, e.g., a water-proof connection, can be established between the container and an energy source, e.g., a wall socket. In this way, regulatory and safety requirements can be met.
The charging unit may provide energy to the electric oral-hygiene device in an inductive manner—although a direct electrical connection is also contemplated. The container may comprise a pin disposed in a complementary recess in the electric oral-hygiene device, which pin may serve for positioning the electric oral-hygiene device correctly with respect to an inductive energy transmitter (e.g., a coil) of the charging unit.
A kit can comprise the container and an energy supply unit having an electrical output connector that is connectable to the electrical input connector of the container, as is described herein. The electrical safety barrier for usage in a wet environment can then be implemented in the energy supply unit, which transforms the high AC voltage provided by a wall socket into a lower (e.g., 3 to 12 V) DC voltage.
In some embodiments, the charging unit comprises a charging prioritization unit for selectively controlling the supply of energy provided via the electrical input connector to the charging unit and via the charging unit then selectively to the electrical output connector. The charging prioritization unit may be arranged to apply pre-programmed (or hard-wired) rules for selectively providing energy for charging of the electric oral-hygiene device and for charging of an external device connected to the electrical output connector. Optionally energy may also be provided to further units, e.g., a sanitizing unit, a feedback element, or a powered fan (which units are described in more detail further below).
As one rule applied by the charging prioritization unit, energy supplied via the electrical input connector can be directly routed to the electrical output connector if the electric oral-hygiene device has been removed from the container or if the electric oral-hygiene device is already fully or sufficiently charged (i.e., selection in dependence on the charging state of the electric oral-hygiene device). An external device connected with the electrical output connector can then be provided with electrical energy, e.g., for the purpose of charging the external device. A further rule that may be applied by the charging prioritization unit is the following: if the electric oral-hygiene device is still to be charged, energy supply to the electrical output connector may be inhibited or may be controlled to be intermittent so that charging of the electric oral-hygiene device is prioritized.
In some embodiments, the container comprises a user-input unit, e.g., a switch or a wireless receiver unit for receiving signals from an external device, by which a user can set a prioritization of the charging unit or can override a charging prioritization unit if such is present. The user-input unit may even be arranged such that the user can reprogram the charging prioritization unit, e.g., the user-input unit may be a Bluetooth receiver that can receive commands from a computer having a Bluetooth transmitter. By such a user-input unit it may be achieved that energy is directly provided to the electrical output connector, instead of to the charging unit, for charging of the electric oral-hygiene device to thus manually prioritize the electrical output connector (and thus, e.g., prioritize charging of an external device over charging of the electric oral-hygiene device).
In some embodiments, the container comprises an energy source, e.g., a rechargeable accumulator or a replaceable energy source such as a battery. The charging unit (which may be controlled by the charging prioritization unit) may use the energy source to charge the electric oral-hygiene device and/or an external device via the electrical output connector (in particular in cases when no energy is provided via the electrical input connector). In case of a rechargeable energy source, the charging unit may charge the energy source when it is not fully charged, e.g., when the electric oral-hygiene device is already fully charged. The charging prioritization unit, if present, may take over the selective control over the charging sequence.
In some embodiments, the container further comprises at least one feedback element for indicating, e.g., a status of the charging unit. The status information may comprise at least one of a “no activity” feedback, a “charging of device ongoing” feedback, a “charging of device completed” feedback, a “energy provided at electrical output connector” feedback, a “charging of internal accumulator ongoing” feedback, an “internal accumulator is discharged” feedback, and the like. One skilled in the art would realize that the available feedback indications will depend on the configuration of the container; if, e.g., no rechargeable accumulator is present, then the feedback possibilities do not include a feedback related to the rechargeable accumulator.
The feedback element may be arranged for at least one of an audible, visual, or tactile feedback. The feedback element may be a light emitting element such as an LED, e.g., optionally a multi-color LED; a sound emission element, such as, e.g., a speaker and/or a motor-based sound generator; or a vibrator element, e.g., a piezo-vibrator. The feedback element may be arranged on an outer side (or outer surface) of the container, in particular if it is a visual feedback element. In some embodiments, the feedback element can be arranged at the removable electric oral-hygiene device, which can be used to take over the feedback function, e.g., an LED provided at the (visible) housing of the electric oral-hygiene device may be used for visual feedback—or a motor of the electric oral-hygiene device may be used for tactile and/or audible feedback.
In some embodiments, the container comprises a sanitizing unit arranged for sanitizing at least a part of the electric oral-hygiene device, e.g., a functional head of the electric oral-hygiene device, such as a brush head. The functional head may be attachable to and detachable from the handle of the device; and the container can be structured and configured to receive the functional head detached from the handle. For example, the sanitizing unit may comprise an ejector unit (e.g., a piezo-element-driven ejector nozzle) for ejecting a small amount of a sanitizing fluid (e.g., in the form of a fine spray) onto at least the part of the device to be sanitized when the container is closed. Alternatively or additionally, the sanitizing unit may comprise a UV light source for emission of germicidal ultraviolet radiation towards at least the part of the electric oral-hygiene device to be sanitized.
In some embodiments, the container can be arranged so that a display device is supported by the container when the container is in the open position. The container can then be equipped with at least one receiving structure for holding the display device, e.g., in an upright or slightly inclined position. The at least one receiving structure may in particular be arranged to hold in place a display device of a particular geometry. In some embodiments, at least two receiving structures are present, which may comprise a cut-out provided in the first casing part and a recess in the second casing part, wherein the recess may in particular be provided in a replaceable inlay so that the recess can be adapted to the size of the display device to be received. The display device may comprise, e.g., a smartphone.
In some embodiments, the container may include a humidity-removal system. The humidity-removal system may be active and/or passive. In some embodiments, the humidity-removal system comprises a reservoir having a moisture-absorbing material. The reservoir may be replaceable, e.g., the reservoir may be snap-connected to the container. Alternatively or additionally, the reservoir may be arranged so that the moisture-absorbing material can be replaced. The moisture-absorbing material may be a silica gel, but other known moisture-absorbing materials are can be used as well. Additionally or alternatively, the humidity-removal system may comprise an active and/or passive venting system, e.g., at least one venting opening and/or a powered fan.
In some embodiments, the container can be equipped with at least one replaceable inlay. E.g., at least one of the casing parts may be arranged to have a generally shell-like structure in which an inlay may be snap-fitted or press-fitted. Such an inlay may be adapted to a particular electric oral-hygiene device. The inlay may comprise deformable foam material to allow adaptation to differently shaped electric oral-hygiene devices.
The second casing part 20 serves in the shown embodiment as storage portion of the container 1. The second casing part 20 together with the side walls 41 and 42 forms a shell-like tray. An inlay 200 is inserted into this tray. The inlay 200 is in particular a replaceable inlay so that it can be cleaned or replaced by another inlay to adapt the container to receive other items or to replace a soiled inlay by a fresh inlay. The inlay 200 has four depressions 201, 202, 203, 204 of which depressions 202, 203, and 204 are interconnected. Generally, the inlay 200 may have at least one depression, but any other number of depressions is possible as well. A depression 201 is shaped for receiving the removable electric oral-hygiene device (see
In some embodiments the container comprises at least one further electric part connected with at least one of the previously mentioned parts such as a charging prioritization unit 240, a user-input unit 245, a feedback element 235, a rechargeable battery 250, a humidity-removal system 260 and/or a sanitizing unit 270 that may each be electrically coupled with the charging unit 230. A container as proposed may comprise one or several of these further electric parts and respective electric connections.
In some embodiments, the charging unit 230 comprises a charging circuit 231 and a charging coil 232 for wireless, inductive energy transfer to a charging coil of the electric oral-hygiene device 400, where the charging coil 232 may be arranged in a pin-like structure 233 adapted for sliding into a form-fitting recess 401 of the electric oral-hygiene device 400 so that the electric oral-hygiene device 400 has a defined position to the charging coil 232 during charging.
In some embodiments, the charging unit 230 comprises a charging prioritization unit 240 for prioritizing the provision of energy received via the electrical input connector 210 or alternatively or additionally drawn from a rechargeable energy source 250. The prioritization unit 240 may apply at least one of the following prioritization rules, where these rules may be present as original default settings or may be chosen via the user-input unit (which rules are given as examples—any other prioritization rule may be applied as well):
A user-input unit 245 may be provided for switching between prioritization rules, for overriding a prioritization rule by a user defined prioritization rule or for reprogramming the prioritization unit 240. The user-input unit 245 may thus be realized as a simple switch to switch between predefined prioritization rules or, e.g., as a Bluetooth based receiving device for wireless reprogramming of the prioritization unit 240 via an external device such as a smartphone (to which a respective reprogramming app has been loaded), tablet, or a computer.
The container may have a feedback element 235 for indicating, e.g., a charging state as has already been described. The feedback element 235 may be arranged at the outer side of the container. In some embodiments, the charging unit 230 is controllably coupled with the electric oral-hygiene device 400 so that the charging unit 230 can use a feedback element arranged at the removable electric oral-hygiene device 400, e.g., a light emission element 420 or a motor 430 of the electric oral-hygiene device 400 to provide visual, acoustic or tactile feedback.
