Background

The following description includes information that may be helpful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any patent publication specifically or implicitly referenced is prior art.

Generally, a fragrance spreading device includes a base unit and a cartridge attached to the base unit. The fragrance, typically in liquid form, is then sucked or pulled from the cartridge so that it passes through the base unit before exiting the device. Such devices are problematic because even with different scent cartridges, which retain previous scents, they do not diffuse the scent around the device, and are often uncomfortable to hide in an attempt to keep them at locations that take a long time to drift to a preferred location.

All patent publications herein are incorporated by reference to the same extent as if each individual patent publication or patent application was specifically and individually indicated to be incorporated by reference. Where a definition or use of a term in an incorporated reference is inconsistent or contrary to the definition of that term provided herein, the definition of that term provided herein applies and the definition of that term in the reference does not apply.

Accordingly, there remains a need for improved diffusion devices and cartridges that address the above-mentioned problems.

Disclosure of Invention

The present subject matter provides devices, systems, and methods for a fragrance dispensing unit and cartridge that can be used together to disperse fragrance from the cartridge into an area surrounding the dispensing unit.

Contemplated dispensing units may include a base having a lower surface and an upper surface, wherein the base includes a fan and a power source configured to provide power to the fan. The first set of magnets may be disposed at or below the upper surface of the base.

The unit may also include a cover having a lower surface and an upper surface, wherein the lower surface includes a second set of magnets having a polarity opposite to a polarity of the first set of magnets such that the cover is magnetically attached to the base via magnetic coupling between the first set of magnets and the second set of magnets.

The base or cover may include a third set of magnets. When the third set of magnets is disposed at or below the upper surface of the base, the third set of magnets have the same polarity as the second set of magnets. In the case where the cover includes a third set of magnets, the third set of magnets have the same polarity as the first set of magnets. In either case, by rotating the cover relative to the base, the magnetic coupling becomes a repulsive force, thereby facilitating removal of the cover from the base.

The base may include a recessed central portion surrounded by an outer wall forming an upper surface of the base, the recessed central portion configured to receive the cartridge.

The scent cartridge can be disposed on the recessed portion of the base such that the scent cartridge is adjacent to and above the fan in the base. Contemplated scent cartridges may include a scent reservoir in which scents or scents are stored prior to emission. In a preferred embodiment, the perfume holder comprises a plurality of scented beads that evaporate over time. However, the fragrance reservoir may alternatively comprise a gel or liquid stored within a housing. Contemplated scented beads include Ethylene Vinyl Acetate (EVA) beads that have previously absorbed one or more scented solutions.

It is envisaged that the fragrance box may comprise a top plate which is suspended above the upper surface of the box by posts extending upwardly from the box to the plate. The top plate may advantageously include artwork or power equipment while also hiding the fragrance reservoir beneath the top plate. Additionally, the top plate may divert and flow air circumferentially from the cartridge.

Advantageously, the scented air does not flow through the base because it flows from the scent reservoir and then out of the cartridge. Thus, when the cartridge is replaced and a new cartridge is used, it is unlikely that there will be any remainder of the previous scent on the base.

Various objects, features, aspects and advantages of the present subject matter will become more apparent from the following detailed description of preferred embodiments along with the accompanying figures in which like numerals represent like parts.

Detailed Description

In the following discussion, reference will be made multiple times to a server, service, interface, portal, platform, or other system formed by a computing device. It should be understood that the use of such terms is to be taken to represent one or more computing devices having at least one processor configured to execute software instructions stored on a computer-readable tangible non-transitory medium. For example, a server may include one or more computers that function as a network server, database server, or other type of computer server in a manner that achieves the described roles, responsibilities, or functions.

The following discussion provides a number of example embodiments of the present subject matter. While each embodiment represents a single combination of inventive elements, the inventive subject matter is considered to include all possible combinations of the disclosed elements. Thus, if one embodiment includes elements A, B and C, while a second embodiment includes elements B and D, the inventive subject matter may be considered to include A, B, C or other remaining combinations of D, even if not explicitly stated.

Fig. 1-2 illustrate one embodiment of a fragrance dispensing unit 100, the fragrance dispensing unit 100 having a scent cartridge 130 dispensed within the unit 100. The unit 100 includes a base 102 and a cover or ring 110 magnetically coupled to the base 102, and the cover or ring 110 collectively retains the scent cartridges 130 within the unit 100.

The seat 102 includes an upper surface 106 and a lower surface 108. A fan 150 is disposed within the base 102, the fan 150 being connected to a motor 156 that drives the fan 150. The base may also include electronics 152, and these electronics 152 control a motor 156 so that the fan speed can be changed or the fan 150 turned on or off. A battery 154 may be included for storing power and powering the various components of the base 102. Alternatively or additionally, the base 102 may be coupled to a line voltage to charge the battery 154 and/or power the unit 100. In some embodiments, the battery 154 may be charged by induction.

The base 102 may include a grill 146 disposed above the fan 150, and the grill 146 includes a plurality of holes through which air may flow from the fan and through the grill 146. In this manner, air may flow through the lower surface 108 of the base 102, through the fan 150, and through the grille 156 as indicated by the arrows.

The first set of magnets 116 may be disposed at the upper surface 106 of the base 102 or below the upper surface 106 such that each magnet has the same polarity in the portion closest to the upper surface 106. Thus, for example, where each magnet has a north pole end and a south pole end, all magnets 116 of the first set of magnets will have the same end facing the upper surface 106.

The second set of magnets 118 may be disposed at or above the lower surface 114 of the cover 110 such that each magnet has the same polarity at the portion of the magnet closest to the lower surface 114. It is particularly preferred that the polarity of the second set of magnets 118 is opposite to the polarity of the first set of magnets 116. In this manner, the magnetic attraction between the first set of magnets 116 and the second set of magnets 118 may couple the cover 110 to the base 102.

In some contemplated embodiments, the base 102 may include a third set of magnets 120, the third set of magnets 120 being disposed at or below the upper surface 106 of the base 102. In such embodiments, the polarity of each magnet in the third set of magnets 120 in the portion of the magnet closest to the upper surface 106 is the same, and the polarity of the third set of magnets 120 is opposite the polarity of the first set of magnets 116 and the same as the polarity of the second set of magnets 118. In this manner, when the cover 110 is coupled to the base 102 and rotated relative to the base 102, the third set of magnets 120 and the second set of magnets 118 will generate a repelling force due to the same polarity of the magnets, which will facilitate removal of the cover 110 from the base 102.

In other contemplated embodiments, the cover 110 may include a third set of magnets 120, the third set of magnets 120 being disposed at or above the lower surface 114 of the base 102. In such embodiments, the polarity of each magnet in the third set of magnets 120 in the portion of the magnet closest to the lower surface 114 is the same, and the polarity of the third set of magnets 120 is opposite the polarity of the second set of magnets 118 and the same as the polarity of the first set of magnets 116. In this manner, when the cover 110 is coupled to the base 102 and rotated relative to the base 102, the third set of magnets 120 and the first set of magnets 116 will generate a repelling force due to the same polarity of the magnets, which will facilitate removal of the cover 110 from the base 102.

When the cover 110 is coupled to the base 102, the lower surface 114 of the cover 110 abuts or rests on the upper surface 106 of the base 102. The cover 110 may also include a rim 122 defining the upper surface 112 of the cover 110. The rim extends inwardly from the wall 124 of the cover 110.

The unit 100 may include a scent cartridge 130, the scent cartridge 130 preferably being disposable and removable from the base 102. The scent cartridge 130 has an upper surface 132 and a lower surface 134, the upper surface 132 and the lower surface 134 each having one or more apertures to allow air to flow through the cartridge, for example from the fan 150.

Scent cartridge 130 can include a stand 136 extending upwardly from upper surface 132, and stand 136 supports a top plate 138 that hangs above scent cartridge 130. In this manner, a first end of upright 136 may be attached to scent cartridge 130 and a second, opposite end of upright 136 may be attached to top plate 138. The top panel 138 is preferably sized and dimensioned to cover or conceal all or a portion of the scent cartridge 130.

Advantageously, the top plate 138 may direct some or all of the airflow circumferentially from the base 102 and cassette 130, rather than simply upward as in many prior art devices. This helps to ensure that, for example, fragrance is emitted evenly from the cartridge 130 in the room.

The cartridge 130 may also include a grill 140, the grill 140 being disposed above the fragrance depository 160 in the cartridge 130. The grill 140 ensures that the fragrance depository 160 is not disturbed or that beads 166 or other scented debris in the cartridge 130 is not removed. As shown, the fragrance depository 160 preferably includes one or more quadrants 164 (here four quadrants), each quadrant containing scented beads 166. Contemplated scented beads 166 include those formed from ethylene vinyl acetate. However, in other embodiments, a scented gel or liquid may be placed within the scent reservoir 160. The quarter-cells 164 may be formed by one or more walls 162 within the fragrance reservoir 160.

As shown in fig. 11-12, the top panel 138 may include artwork, which may include images or transparent or translucent portions, such as the tinted glass replica shown in fig. 12.

Alternatively, as shown in fig. 13, the top plate 138 may include a kinetic device or engraving, which itself may change visual appearance based on airflow past the kinetic device or contacting its lower surface. For example, the top plate may include a paper pressing portion that becomes animated/fluttering during use of the fan.

The scent cartridge 130 is preferably placed within the recessed area 128 of the base 102 that is at least partially formed by the wall 126. Recessed areas 128 may include dimples or other protrusions 148. When the cartridge is positioned within the recessed area 128, the projection 148 is inserted into the groove 158 on the cartridge 130. This helps to ensure that the cartridge 130 is placed in place within the recessed area 128. Recessed area 128 is disposed above fan 150.

Once the cartridge 130 is inserted into the recessed area 128 of the base 102, the cover or ring 110 can be placed over the upper surface 132 of the cartridge 130 such that the rim 122 of the cover 110 rests on the upper surface 132 of the cartridge and retains the cartridge 130 within the recessed area 128. In such embodiments, it is contemplated that the upper surface 132 of the scent cartridge 130 is flush with the upper surface of the wall 126. Thus, the diameter of the rim 122 is smaller than the diameter of the cartridge 130.

The upper surface 112 of the cover 110 may include an aperture 115 defined by a rim 122. In this manner, when the cover 110 is attached to the base 102, the posts of the cassette 130 extend through the holes 115 and the top plate 138 will extend over the cover 110.

When the fan 150 is turned on, air passes through the lower surface 108 of the base 150 through the grill 146 of the base 102, through the fan 150. From the fan, the non-scented air enters the scent cartridge 130 through its lower surface 134, passes through the scent reservoir 160, and exits the cartridge 130 at the grill 140. The scented air now exits through the space between the grill 140 and the top plate 138. As described above, the top plate 138 advantageously may cause the scented air to circumferentially diffuse from the cartridge 130. In this manner, scented air flows out of the scented cartridge 130 and out of the device 100 without passing through the base unit 102. Thus, when the cartridge 130 is removed from the base 102, residual scent is not left on the base 102 because changes that occur in the scent cartridge 130 will change the grill 140, scented air passes through the grill 140, and different scents do not mix.

In some embodiments, the cartridge 130 may include one or more light sources. It is contemplated that the light source may be configured to illuminate at a particular time of day via a timer, a direct on/off control, or a signal received by an ambient light sensor. If the top plate contains a transparent or translucent portion, the light source may enhance the visual effect of the artwork or powered device of the top plate.

It is contemplated that the electronic component 152 may be configured to monitor the life of the cartridge 130. Preferably, as described above, when the cartridge 130 is placed on the base unit, the cartridge 130 and the base unit 102 each have electrical contacts that contact each other. In one embodiment, the dimple or other protrusion 148 may include an electrical contact 170, the electrical contact 170 contacting an electrical contact 172 disposed in the recess 158 of the cartridge 130.

For example, when the cartridge 130 is first inserted into the base unit 102, the electronics can start a timer that indicates when the cartridge 130 is inserted into the base unit 102. Through the electrical connection between the cartridge 130 and the base unit 102, the electronic components may receive information about the cartridge, such as the type of cartridge 130 and some code, indicia, or other means to indicate that the cartridge 130 is authentic rather than a counterfeit cartridge. This information may also include a serial number or other unique identifier to prevent reuse of the cassette 130 and to ensure that the timer will not reset if the same cassette is removed and reinserted.

The electronics 152 may include a processor, memory with stored algorithms, and a PCB with other components. One of the stored algorithms may calculate the current life of the cartridge 130 by calculating the time the cartridge 130 has been opened and inserted into the base 102 and the time the fan 150 is on during insertion of the cartridge into the base 102. Based on the known evaporation rate of the scented beads 166 or other items in the fragrance depository 160, the electronics may multiply the evaporation rate of the scented beads 166 by the time the cartridge has been inserted and the fan is off and multiply the evaporation rate of the scented beads 166 by the time the cartridge has been inserted and the fan is on. Adding these two values will allow electronic component 152 to determine the remaining percentage of scent or the amount of scent available in cartridge 130.

Some information, such as the evaporation rate and the total amount of fragrance of the cartridge 130, may be stored in the cartridge 130 and transferred to the base 102, transferred from a remote source to the base, or stored in the base 102. This is important because different scent cartridges may have different evaporation rates.

It is contemplated that the base 102 may include a transceiver on the electronic element 152, for example, configured to transmit and receive information from a remote source such as a smart phone or other portable computing device. Thus, for example, the base 102 may communicate the remaining life of the cartridge to a user. In some embodiments, a user may control the operation of the base 102 with a portable computing device. In other embodiments, the base 102 may transmit information to a user's device, which may load a website, image, or story related to the cartridge installed in the device 100. The base 102 may also submit the request.

In other contemplated embodiments, the cartridge 130 may include a memory and/or microchip 168, the memory and/or microchip 168 may be used to control, for example, the fan speed associated with the scent. In addition, the microchip 168 or electronics 152 of the base 102 may illuminate when fragrance is emitted. If a counterfeit scent cartridge is used, the electronics 152 and/or microchip 168 of the cartridge 130 may help prevent the base 102 from operating.

It is further contemplated that the device 100 may be opened/closed by simply touching a ring or other portion of the base 102. This may allow power to be applied or removed through the capacitor. Additionally, the bottom of the base 102 may have slots to attach the base 102 to a mount or other support. The slots may have positive/negative connections therein so that a mount or other support may transmit power to the base 102.
