Description

[0001] The invention relates to a device for controlling the ejection of spray bursts from a bracelet according to the preamble of claim 1.

[0002] A number of fragrance delivery devices in the form of wristbands are available on the market today, offering consumers the opportunity to experience and apply pleasant fragrances in their immediate environment without having to carry traditional perfume bottles.

[0003] These so-called scented bracelets consist of or feature ceramic inserts, stone, especially lava rock, activated carbon, or mixtures of materials into which the desired scent is infused and stored. When the bracelet is worn, the increased temperature caused by the wearer's body heat causes the scents stored in the ceramic materials, stones, or textiles to slowly evaporate, spreading a pleasant fragrance throughout the wearer's surroundings.

[0004] However, these well-known scented bracelets cannot be influenced in any way, and the scent is released purely randomly via ambient heat and the user's body heat until the scent has escaped from the storage medium. Thus, in particularly warm environments, scent is released even when it is not desired, and in cooler environments, the bracelet becomes virtually ineffective.

[0005] Large-capacity fragrance dispensers are also known for the home. These contain cartridges containing a desired fragrance and feature an electronic control system that releases the fragrance at preset intervals via a spray device. These electronic control devices can also be combined with an app that can be used to program the fragrance dispenser. However, due to their design, these devices are not suitable for wear by a user. They also do not allow the insertion of any fragrance, but are tied to the manufacturer's cartridges.

[0006] The subject of KR 10 2019 0 013 334 A is a wristband with an outer surface and a reservoir for a liquid in the form of a disinfectant. The reservoir is designed as a tank, and the outer surface has a spray device for ejecting the liquid in individual sprays. This is done by an electronic control.

[0007] A fragrance bracelet which emits bursts of fragrance using an electronic control system is also the subject of WO 2015 / 189866 A1.

[0008] Finally, DE 10 2017 205 070 A1 shows a stationary scenting device.

[0009] The object is therefore to further develop a device for controlling the emission of sprays from a bracelet in such a way that a high degree of individualisation is ensured.

[0010] This object is achieved by the characterizing feature of claim 1. Advantageous embodiments can be found in the subclaims.

[0011] A fragrance bracelet with a device according to the invention has an outer surface and at least one reservoir designed as a tank for a liquid fragrance, as well as a spray device on the outer surface for ejecting the fragrance in individual bursts. This spray device is controlled by an electronic controller. This makes it possible to spray specific bursts of fragrance when desired by the user wearing the bracelet. Thus, the fragrance does not spread independently, but rather in a controlled manner under appropriate control by the electronics or the user.

[0012] Advantageously, the electronic control unit is connected wirelessly to a mobile computer, particularly a mobile phone or smartwatch. This allows the electronic control unit for dispensing the fragrance to be conveniently controlled using an app on a mobile phone or smartwatch.

[0013] In a particularly advantageous embodiment, this smartwatch is integrated into the scented bracelet. The scented bracelet features lugs for the corresponding smartwatch. This means that the mobile app for controlling the scented bracelet is integrated directly into the bracelet.

[0014] The wristband is preferably made primarily of a soft material such as silicone, rubber, or caoutchouc. This ensures a comfortable fit. Of course, the wristband can also contain additional elements, such as a metal clasp or closure, and, of course, the electronics and the tank, which are made of other materials.

[0015] Advantageously, a battery is provided to power the electronic control system, for which the bracelet has a battery compartment. This battery can be a button cell, for example.

[0016] In an advantageous embodiment, the wireless connection is a Bluetooth connection. This ensures that the electronic control unit can be easily connected to a mobile phone or smartwatch.

[0017] In an advantageous embodiment, the wristband has sensors for the fragrance fill level within the reservoir and the battery charge level. This sensor data can then be displayed directly on the mobile phone or smartwatch.

[0018] In a further advantageous embodiment, the bracelet has a proximity sensor which causes the electronics to initiate a spray when the bracelet approaches the user's skin surface.

[0019] In a further embodiment, the bracelet can also have multiple reservoirs designed as tanks for different fragrances, which are then emitted by the same or different spray devices controlled by the same electronics, as desired by the user. This allows the user to choose a different fragrance during the day than in the evening.

[0020] A particular embodiment of the invention relates to a device for controlling the discharge of spray bursts from a wristband, as described above. Such a device comprises a computer, in particular a mobile phone or smartwatch, for control. Software, such as an app, runs on this computer, which records parameters of the wristband and external parameters and controls the discharge according to a relationship between the parameters of the wristband and the external parameters.

[0021] The external parameters can be time, temperature or calendar data and the parameters of the bracelet are, for example, the level of the fragrance in the tank and the battery status.

[0022] This control makes it possible to trigger the sprays at fixed time intervals. Additionally, a signal can be emitted before each spray, prompting the user to move their arm toward their face or neck to ensure the fragrance is released in the correct location. Control via an external calendar is also possible, so that the fragrance can be released, if necessary, after prior notification by a signal, shortly before contact with other people, such as a meeting or a visit to the theater.

[0023] The announcement of the ejection can be made by an acoustic, optical or haptic signal, e.g. a vibration signal.

[0024] An embodiment of the invention will be explained in more detail below with reference to the accompanying drawings. These show Fig. 1 is a representation of a bracelet according to the invention seen from the inside facing the user; Fig. 2 a representation according to Fig. 1 seen from the outside facing away from the user; Fig. 3 a schematic representation of the hand and wrist of a user with a bracelet according to the invention according to Fig. 1 and Fig. 2, seen from above; Fig. 4 a representation according to Fig. 3 seen from below.

[0025] The Fig. 1 and Fig. 2 show, from the inside and from the outside, a bracelet 1 according to the invention, having an outer side 2 and an inner side 12. The bracelet 1 has at its two ends lugs 7 and 8 respectively for receiving a watch, in particular a smartwatch, which are not described in detail but are based on the receiving devices of the smartwatch to be attached.

[0026] Fig. Figure 1 shows that the bracelet 1 has a reservoir in the form of a tank 3 accessible from the inside 12, which serves to hold a fragrance. Fig. 2, a spray device 4 is located approximately in the center of the bracelet 1, which serves to emit bursts of this fragrance. This is controlled by an electronic controller 5 integrated into the bracelet 1 in conjunction with a spray actuator 13, which is located opposite the spray device 4.

[0027] There is a radio connection (not shown in detail) between this electronic control 5 of the bracelet 1 and a mobile computer, which in the illustrated embodiment is a Fig. 3 and Fig. 4. This wireless connection is preferably a Bluetooth connection, for which a Bluetooth module 14 is integrated into the wristband 1.

[0028] The bracelet 1 itself is preferably made of a soft material such as silicone, rubber or caoutchouc, but may also be made of any other material or combination of materials that allow the inclusion of the components shown in this description.

[0029] To supply power to the electronic control 5 and the other power-consuming components of the bracelet 1, the latter has a compartment 9 for a battery, which may be a button cell, for example.

[0030] Furthermore, the bracelet has a sensor 10 for the fill level of the fragrance in the tank and / or a sensor (not shown) for the charge level of the battery in the receiving compartment 9. The data from both sensors can be evaluated by the electronic control system.

[0031] Preferably, the bracelet has a proximity sensor 11, upon which the electronic control 5 approaches the skin surface of a user, triggers a spray burst 5 from the spray device 4, triggered by the spray actuator 13.

[0032] In a further embodiment not shown, the bracelet 1 can also have a further tank for holding a further fragrance, which can be ejected via the same spray device 4 or the spray actuator 13 controlled by the same electronic control 5, so that different fragrances can be applied at different times of the day or on different occasions.

[0033] The subject of the invention is therefore a device for controlling the discharge of spray bursts from the wristband 1, which is controlled by an external computer, in particular the smartwatch 6. This device records both parameters of the wristband 1 and external parameters and controls the discharge according to a relationship between the parameters of the wristband 1 and the external parameters. The external parameters of the wristband are, for example, time and / or temperature and / or calendar data. The parameters of the wristband 1 are, for example, the fill level of the tank 3 or the charge level of the battery.

[0034] Furthermore, the wristband 1 can have a gyroscopic sensor 15 and / or an acceleration sensor 16 to trigger the electronic control 5 to release a spray from the spray device 4 in response to certain gestures by the user. This enables gesture control of the fragrance dispenser.

[0035] The bracelet also has a USB-C port 17, via which data can be exchanged and the battery in the battery compartment 9 can also be charged, especially if it is a rechargeable battery.

[0036] In addition to activating the spray device 4, the spray actuator 13 can also monitor the precise fragrance delivery. It can detect when and how much fragrance has been sprayed based on user input or automated settings, thus providing, alongside the fill level sensor, an indication of consumption and, in particular, the consumption rate.

[0037] The wristband 1 according to the invention is preferably controlled by the electronic controller 5, which is connected to software stored in the smartwatch or an external mobile phone via a Bluetooth connection. This is an app that allows a user to log in with a username and password and then displays the battery level, the fragrance level, and other relevant data of the wristband. This app can also integrate the user's calendar to provide timely reminders to apply fragrance before scheduled events. The configuration of the fragrance spray device can also be saved, as can the proximity detection of the proximity sensor 11, gesture controls, and historical usage data.

[0038] A filling device for the tank 3 is not shown in detail. This can be, for example, a syringe through which the fragrance is introduced into the tank 3 with the help of an elastic valve or a screw-on or click-off cap so that the fragrance can be filled in a similar way to a lighter.

[0039] The bracelet according to the invention works as follows.

[0040] First, a Smartwatch 6 is inserted into the lugs 7 and 8 of the bracelet 1, so that the Fig. 3 and Fig. 4 is created. The wristband 1 is put on and taken off with the smartwatch 6 via the lugs 7 and 8, respectively. In another, more convenient embodiment (not shown), the wristband 1 itself has a clasp so that it can remain permanently connected to the smartwatch 6 via the lugs 7 and 8.

[0041] After putting on the bracelet 1 with the smartwatch according to Fig. 3 and Fig. 4, the bracelet is ready for use, provided it has been previously filled with a battery and the appropriate fragrance. If necessary, the user data must be transferred during initial use, and the user must log into the system using a special app to then set the bracelet's parameters. Once this has been done, the user can adjust the spray bursts as desired. Either the electronics 5 of the bracelet 1 connects to their calendar via the app, so that a fragrance is always released in good time before certain calendar events. In this case, it is advantageous for the electronic control 5 to emit an acoustic signal to remind the user to place the bracelet 1 near their neck or another part of their body to which they wish to apply the fragrance.

[0042] Alternatively, the user can also activate the proximity sensor 11 by bringing the bracelet with the spray device close enough to their skin surface. As soon as the distance falls below approximately 20 cm—this is adjustable—the electronic control 5 generates a spray from the spray device 4.

[0043] Alternatively, certain gestures can be programmed which can be detected by the acceleration sensor or the gyroscope, so that in the case of certain linear movements or rotational movements of the user's hand, a spray burst is ejected by the spray device 4.

[0044] The bracelet according to the invention thus enables a controlled release of fragrances that can be determined by external and internal parameters, depending on the user's wishes and preferences.

[0045] In a further embodiment (not shown), the bracelet 1 has a second tank, allowing the user to switch between these two tanks and the fragrances they contain, for example, selecting one perfume for the day and another for the evening. Switching between these two tanks can also be preset using the electronic control 5 and the calendar function.
