The details of one or more variations of the subject matter described herein are set forth in the accompanying drawings and the description below. Other features and advantages of the subject matter described herein will be apparent from the description and drawings, and from the claims.
The accompanying drawings, which are incorporated in and constitute a part of this specification, show certain aspects of the subject matter disclosed herein and, together with the description, help explain some of the principles associated with the disclosed implementations. In the drawings:
Implementations of the current subject matter include devices relating to vaporizing of one or more materials for inhalation by a user. The term “vaporizer” is used generically in the following description and refers to a vaporizer device. Examples of vaporizers consistent with implementations of the current subject matter include electronic vaporizers, electronic cigarettes, e-cigarettes, or the like. In general, such vaporizers are often portable, frequently hand-held devices that heat a vaporizable material to provide an inhalable dose of the material.
The vaporizer device can include a power supply, such as a rechargeable battery. Certain rechargeable batteries may need to be recharged quickly so that the user can continue to use the vaporizer device after a period of time. Typical vaporizers may be rechargeable by, for example, connecting the device to an external power supply via a wired connection or a USB connection with a desktop computer, and/or connected with a wall outlet. Typically, the vaporizer battery may discharge after use and the user may not be able to locate an external power source quickly. For example, a computer or a wall outlet can typically be immobile and/or difficult to transport. Thus, a charging case assembly, consistent with implementations of the current subject matter, can desirably provide portable charging for a vaporizer device.
Currently available portable charging devices, particularly those available for vaporizer devices may be heavy, bulky (e.g., not volumetrically compact), and/or difficult to carry; difficult to locate within a bag or home; and/or difficult to open and/or close, and/or may not properly secure and/or protect a vaporizer device. A vaporizer charging case system, in accordance with implementations of the current subject matter, can desirably provide a low profile charging case assembly that can secure and/or provide power to a vaporizer device. The charging case assembly can be lightweight and/or less bulky. The charging case assembly can be generally aesthetically pleasing and/or easy to use. The charging case assembly can be easy to open and/or close, such as by allowing a user to open and/or close the charging case assembly with one hand, thumb, or finger. In some implementations, the charging case assembly can be dust, lint, and/or water resistant, and/or may limit dust or liquids from entering the interior volume of the charging case assembly. The charging case assembly can be easily cleaned and accessed. The charging case assembly can have rounded edges. The charging case assembly can be made of a corrosion resistant material, can be made of a biocompatible material, can be made of plastic, aluminum, or other materials.
A charging case assembly for a vaporizer device, consistent with features of one or more implementations of the current subject matter, may provide advantages and improvements relative to existing approaches, while also introducing additional benefits as described herein.
As described below, the charging case assembly 100 can include a housing 103 surrounding the internal components of the charging case assembly 100 and/or providing access to one or more internal components of the charging case assembly 100. The housing 103 can include an upper housing 102 and a lower housing 104. The lower housing 104 may be pivotably coupled to the upper housing 102, such as by a hinge assembly 150 that allows the charging case assembly 100 to form an open configuration where the upper housing 102 is pivoted away from the lower housing 104 and a closed configuration where the upper housing 102 pivoted towards the lower housing 104. In some embodiments, the lower housing 104 may include a rechargeable power supply (e.g., a battery 132) configured to be recharged and to provide power to the vaporizer device 101. The lower housing 104 may further include a coupling mechanism 106 configured to receive and position the vaporizer device 101 within the lower housing 104. The charging case assembly 100 can be in the open position when at least a portion of the upper housing 102 is separated from at least a portion of the lower housing 104, for example, such as when an inner rim 120 of the upper housing 102 separates from an inner rim 126 of the lower housing 104. In some implementations, the charging case assembly 100 is in the open position when the charging case assembly is fully opened. The charging case assembly 100 can be fully opened when the upper housing 102 is entirely disengaged from the lower housing 104 and/or when the upper housing 102 rotates away from the lower housing 104 by an angle of approximately 110 degrees, 90-100 degrees, 100-110 degrees, 110-120 degrees, 120-130 degrees, 120-140 degrees, or other ranges higher, lower, or therebetween. In some implementations, the case assembly is in the open position when at least a portion of the upper housing 102 disengages from the lower housing 104 by any distance.
In some implementations, the charging case assembly 100 can include a power supply, such as a battery 132. The lower housing 104 can support at least a portion of the battery 132 within the charging case assembly 100. The battery 132 can include any battery, such as a lithium ion battery, among other types of batteries. The battery 132 can be a rechargeable battery.
The battery 132 can be charged through a wired connection, such as a USB charging cable, including a micro USB charging cable, or other charging cables. In some implementations, the battery 132 can be charged through a wireless connection, such as through various wireless charging means. The battery 132 can supply power to the vaporizer device 101 when the vaporizer device 101 is positioned within the charging case assembly 100 and/or otherwise coupled to the charging case assembly 100 in the open position and/or the closed position. In some implementations, the battery 132 can be fully charged within approximately 3-4 hours, 1-2 hours, 2-3 hours, 4-5 hours, or 6-7 or more or less hours. In some implementations, the battery 132 can be approximately 50% charged in approximately 1.5 hours. The battery 132 can be configured to supply power to the vaporizer device 101. In some implementations, the battery 132 can fully charge the vaporizer device 101 up to or more than five times before the battery 132 is fully discharged. As mentioned below, the battery 132 can be charged when the charging case assembly 100 is in the open and/or closed position.
The upper housing 102 can include various portions that are made of the same or varying materials. In some implementations, the upper housing 102 includes a uniform material. In this context, uniform is used to describe an implementation in which the upper housing is formed substantially of a same material or type of material, for example, such that one or more properties such as visual appearance, opacity, tactile feel, or the like are at least approximately consistent along a surface of the upper housing. In other implementations, at least a portion of the upper housing 102 can include a material that is different from some other portion (or, optionally, a remainder) of the upper housing 102, as explained below. In some implementations, the upper housing can be made of an opaque material, a transparent material, a translucent material, and/or a combination of one or more such materials. Transparent and translucent refer to materials that are not 100% opaque, for example, materials with opacity in a range of 1% up to 100%. In one example implementation, at least a portion of the upper housing can be made out of a translucent material (e.g., a material having less than 100%, in some examples one of 1%, 5%, 10%, 20%, 30%, 50% or some other value of opacity), thereby allowing a user to view contents and/or features contained within the charging case assembly 100. The transparent material of the upper housing 102 and/or the lower housing 104 may allow visualization of an illuminating device indicator (e.g., illuminating indicator 687 shown in
The upper housing 102 can have an exterior shape that is generally trapezoidal, generally rectangular, or some other shape when viewed from above (e.g., the various possible shapes for the upper housing can representative of a cross section of the upper housing taken when the upper housing 102 is closed and in a plane at least approximately parallel to the vaporizer device when held in the charging case assembly). The upper housing 102 can have an outer surface 112 that includes an upper portion 113 and/or an outer rim surface 114. The outer rim surface 114 can be tapered upwardly and inwardly towards the upper portion 113. The outer rim surface 114 can extend from an outer perimeter of the upper housing 102 to the upper portion 113.
In some implementations, the upper housing 102 can include an inner surface 116. The inner surface 116 can include an inner portion 117 that can be raised relative to the outer perimeter of the upper housing 102. The inner portion 117 can be positioned inwardly and upwardly, relative to the outer perimeter of the upper housing 102. The inner portion 117 can be positioned approximately parallel to the outer surface 112. The inner surface 116 of the upper housing 102 can include an inner rim surface 118 that can extend from the inner rim 120 of the inner surface 116 to the inner portion 117. The inner rim surface 118 can be tapered upwardly and inwardly, relative to the inner rim 120. The inner rim 120 can extend along a perimeter of the inner surface 116. The inner rim 120 can be approximately flat and/or rounded, among other configurations.
The inner rim 120 can include a magnet receiver 122. As shown in at least
In some implementations, the upper housing 102 can include a hinge housing protrusion 152 that can extend downwardly from the inner rim 120. The hinge housing protrusion 152 can at least partially surround at least one hinge component of the hinge assembly 150. In some implementations, the upper housing 102 can include one, two, three, four, or more hinge housing protrusions 152.
The lower housing 104 can surround and/or support at least a portion of the internal components of the charging case assembly 100. The lower housing 104 can be shaped to correspond to the shape of the upper housing 102. In some implementations, the lower housing 104 can have a same or similar shape to the upper housing 102. For example, the lower housing 104 can include a generally trapezoidal shape, rectangular shape, or other shape.
The lower housing 104 can have an inner rim 126 that extends along at least a portion of an outer perimeter of the lower housing 104. The inner rim 126 can be generally flat and/or rounded. The inner rim 126 can be configured to contact the upper housing 102 when the charging case assembly 100 is in the closed position. The inner rim 126 can support one or more other components of the charging case assembly 100. For example, the inner rim 126 can support at least a portion of the frame 170 within the interior volume of the charging case assembly 100 such as within the lower housing 104, as explained below.
The lower housing 104 can include one or more hinge recesses 153. The hinge recesses 153 can be positioned along a portion of the inner rim 126 of the lower housing 104. The hinge recesses 153 extend into a sidewall of the lower housing 104. The hinge recesses 153 can be shaped and/or sized to receive the corresponding hinge housing protrusion 152. The hinge recesses 153 can include one, two, three, or four or more hinge recesses 153 to correspond to the number of hinge housing protrusions 152. The hinge recesses 153 can be sized and shaped to receive the hinge housing protrusions 152.
The lower housing can include an inner rim surface. The inner rim surface can include a first sidewall 155A. The first sidewall 155A can be positioned on the hinge side 133 of the lower housing 104. The first sidewall 155A of the lower housing 104 can include one or more hinge rod slots 154. The hinge rod slots 154 can extend along a portion of an inner surface of the sidewall of the lower housing 104. In some implementations, the hinge rod slots 154 can extend from a side portion of one or more of the hinge recesses 153. In some implementations, the hinge rod slots 154 may extend through a portion of a thickness of the sidewall of the lower housing 104. The hinge rod slots 154 can be configured to receive at least a portion of at least one component of the hinge assembly 150. The hinge rod slots 154 can receive a corresponding cam rod 158 of the hinge assembly 150.
The lower housing 104 can include a second sidewall 155D positioned opposite the first sidewall 155A. The second sidewall 155D can include a recessed portion 128. The recessed portion 128 can extend inwardly towards the interior volume of the lower housing 104 and/or downwardly from the inner rim 126 along a portion of the second sidewall 155D towards the bottom side of the lower housing 104. The recessed portion 128 can be positioned at a rearward end portion of the second sidewall 155D of the lower housing 104. In some implementations, the recessed portion 128 can be positioned on other portions of the second sidewall 155D and/or other sidewalls of the lower and/or upper housing 104, 102. The recessed portion 128 can be desirably shaped and/or positioned to allow a user to more easily open and/or close the charging case assembly 100, such as by using the user's thumb, finger, or hand. The recessed portion 128 can allow the user to pull up on at least the inner rim 120 of the upper housing 102 to separate the upper housing 102 from the lower housing 104. In some implementations, the recessed portion 128 can allow the user to push down on the lower housing 104 to separate and/or rotate the upper housing 102 and/or the lower housing 104.
The lower housing 104 can include a charging port 130. The charging port 130 can be desirably positioned to allow a power supply cable 129 to be connected with the charging case assembly 100. The charging port 130 can be shaped to allow the power supply cable to pass through a sidewall of the lower housing to charge the battery 132 positioned within the charging case assembly 100. The charging port 130 can be positioned on a third sidewall 155C of the lower housing 104 that connects the first and second sidewalls 155A, 155D. The charging port 130 can extend through the third sidewall 155C to allow the battery 132 (e.g., power supply) to be charged with and/or without the charging case assembly 100 in the open and/or closed position. For example, the battery 132 of the charging case assembly 100 may be charged while either in the open position or in the closed position. In some implementations, the charging port 130 is positioned centered along the third sidewall 155C. In some implementations, the charging port 130 is positioned offset from the central axis of the case assembly, such as closer to the hinge side 133 and/or the opening side 131 of the lower housing 104. The charging port 130 can be positioned in other regions of the charging case assembly 100 for easy access to charge the battery 132 of the charging case assembly 100.
As shown in
The PCBA 185 can include a switch 160, and/or a microcontroller, and circuitry. The microcontroller can include the operating logic and software instructions for controlling certain features or parameters of the charging case assembly 100. In some embodiments, the microcontroller can include operating logic and software instructions for providing one or more indicators, such as illuminating one or more lights (e.g., LED's) associated with either the charging case assembly 100 or the vaporizer device 101. For example, the microcontroller can include operating logic and software instructions that are dependent upon activation of a sensor or a switch, such as switch 160.
In some embodiments, the charging case assembly 100 consistent with implementations of the current subject matter may also include one or more inputs, such as buttons, dials, or the like, and/or sensors, including accelerometers or other motion sensors, capacitive sensors, flow sensors, or the like. These sensors may be used by the charging case assembly 100 to detect user handling and interaction. For example, detection of a rapid movement (such as a tapping or shaking motion) of the charging case assembly 100 may be interpreted by the microcontroller (e.g. through receipt of a signal from one or more of the sensors) as a user command to provide an indication of either a charging state (e.g., charged or charging) or charging level (e.g., battery is 50% charged, etc.), as described in more detail below.
The vaporizer charging case system may include a coupling mechanism 106 configured to couple the vaporizer device 101 with the charging case assembly 100. The coupling mechanism 106 may be configured to receive the vaporizer device 101 in more than one orientation. The coupling mechanism 106 may include a cradle portion (e.g., charging cradle slot 172) configured to receive the vaporizer device 101 and may further include a pair of case electrical contacts 183. The charging cradle slot 172 may be positioned along the lower housing 104 and include an elongated base 107 that is recessed along an inner surface 105 of the lower housing 104 such that a first elongated side of the vaporizer device 101 may be positioned against the base 107 of the charging cradle slot 172 and the pair of case electrical contacts 183 may be positioned adjacent a first end 108 of the base 107 when the vaporizer device 101 is coupled with the charging case assembly 100. The base 107 may be recessed a first distance from the inner surface 105 of the lower housing 104. The first distance may be approximately equivalent to a thickness of the vaporizer device 101. The charging cradle slot 172 may include a pair of elongated sidewalls 155A, 155D extending approximately parallel to each other along opposing sides of the base 107 and a pair of end sidewalls 155B, 155C extending between the pair of elongated sidewalls 155A, 155D. The pair of case electrical contacts 183 may be positioned along a first end sidewall of the pair of end sidewalls 155B, 155C. The pair of elongated sidewalls 155A, 155D may be positioned a second distance apart, such that the second distance may be approximately equivalent to a width of the vaporizer device 101. The second distance may be sized to allow a sliding fit between the vaporizer device 101 and the pair of elongated sidewalls 155A, 155D.
In some embodiments, the microcontroller can include operating logic and software instructions for certain security measures. The security measures can include wireless and/or wired security measures. In some implementations, the microcontroller can include a tag reader. The tag reader can be configured to communicate with the vaporizer device 101. The vaporizer device 101 can include a corresponding tag. In some implementations, the vaporizer device 101 can include the tag reader and the charging case assembly 100 can include the tag. When the vaporizer device is positioned within the charging cradle slot 172 of the frame 170, coupled with the case electrical contacts 183, and/or positioned near the charging case assembly 100, the tag reader can receive the tag to determine whether the tag should be authenticated. If the tag is authenticated, the charging case assembly will be allowed to supply power to the vaporizer device 101. If the tag is not authenticated, the charging case assembly may not be allowed to supply power to the vaporizer device 101. In some implementations, the microcontroller can communicate with an external device, such as a mobile device, and/or an external monitor, among other devices through a wireless and/or wired connection. The microcontroller can send measured data and/or device authentication statistics to the external device.
In some implementations, the charging case assembly 100 can include a variety of security measures through the case electrical contacts 183. For example, the charging case assembly 100 can authenticate the vaporizer device 101 through the case electrical contacts 183. In some implementations, the charging case assembly 100 can include a string and/or a validation reader. In some implementations, the vaporizer device 101 can authenticate the charging case assembly via a string and/or a validation reader.
As explained below, the switch 160 can be actuated to determine whether the charging case assembly 100 is in the opened and/or the closed position. The PCBA 185 can be coupled to the lower housing 104 via a variety of connection arrangements, such as press-fit into the lower housing 104 and/or via fasteners, such as screws 182, among other arrangements.
The PCBA 185 can provide an electrical connection between the battery 132 and the case electrical contacts 183. The case electrical contacts 183 can include pins, springs, or any other type of charging contacts that can electronically connect the PCBA 185 with the vaporizer device 101 when assembled. The PCBA 185 can include a retention mechanism 181. The retention mechanism 181 can be configured to couple the vaporizer device 101 with the charging cradle slot 172. The retention mechanism 181 can include a mechanical, electronic, and/or magnetic connection mechanism. For example, the retention mechanism 181 can include one, two, three, four, or more retention magnets. The retention magnets can provide a magnetic contact for the vaporizer device 101. The vaporizer device 101 can be magnetically connected to the retention magnets, such as through the frame 170, when the vaporizer device 101 is placed in the charging cradle slot 172. The magnetic coupling can include a magnetic force that secures the vaporizer device 101 in the cradle portion (e.g., charging cradle slot 172) of the coupling mechanism 106. The retention magnets can help to retain the vaporizer device 101 when the vaporizer device is positioned within the charging cradle slot 172. The retention magnets can help to limit unwanted movement of the vaporizer device 101 within the charging cradle slot 172. For example, a coupling mechanism (e.g., the retention mechanism 181) may include a first magnet 140 positioned adjacent to the pair of case electrical contacts 183. The first magnet 140 may be configured to magnetically couple with a second magnet 640 (shown in
The frame 170 can have an upper surface. The upper surface can be generally flat. In some implementations, the upper surface can have raised and/or recessed portions, and/or can be generally curved. As shown in
The battery cover portion 174 can be positioned near the hinge side 133 of the lower housing 104. The battery cover portion 174 can be positioned on either side of the lower housing 104. The battery cover portion 174 can be desirably positioned to cover the battery 132 near the charging port 130 and/or near the hinge assembly 150.
In some implementations, the frame can include a plurality of illuminating indicators 176, which can optionally be LEDs (light-emitting diode) or other light sources. The cover portion sidewall 175 of the battery cover portion 174 can include one or more illuminating indicators 176, such as one, two, three, four, five, six, or more illuminating indicators 176. The illuminating indicators 176 can flash, change colors, and/or brighten, or provide other indications that the charging case assembly 100 is in the closed and/or opened position. The illuminating indicators 176 can flash, change colors, brighten, produce a sound or haptics, and/or or send a message to the user, or provide other indications showing that the charging case assembly 100 is actively charging, that the charging case assembly is fully charged (if on charge), the level of case charge (e.g., when not actively charging), and/or the like. For example, in some implementations, when the charging case assembly 100 is actively charging, the illuminating indicators 176 can illuminate, such as through progressive illumination. The illuminating indicators 176 can reduce in brightness and/or number of lit up illuminating indicators to show that the case is in an actively charging state or that the charging case assembly 100 is plugged into a power supply cable 129. The illuminating indicators 176 can illustrate a level of charging. For example, when the battery 132 is at a charging level of approximately 0-25%, one illuminating indicator can pulse; when the battery 132 is at a charging level of approximately 25-50%, a first illuminating indicator can be lit and a second illuminating indicator can pulse; when the battery 132 is at a charging level of approximately 50-75%, the first and second illuminating indicators can be lit and a third illuminating indicator can pulse; when the battery 132 is at a charging level of approximately 75-100%, the first, second, and third illuminating indicators can be lit and a fourth illuminating indicator can pulse, etc. In some implementations, when the battery 132 is fully charged, each of the illuminating indicators 176 may be steadily lit and/or pulse.
In some implementations, when the charging case assembly 100 is moved into the opened position, the illuminating indicators 176 can be progressively illuminated depending on the charging level, with the brightness of the last indicator proportional to the charging level, for example. Similar to the charging level illuminating indicators, in this example implementation, the illuminating indicators 176 can pulse or have varying degrees of brightness depending on the charging level.
In some implementations, if the charging case assembly 100 is in the opened position and the vaporizer device 101 is positioned within the charging case assembly 100 and/or is properly connected to the charging case assembly 100, the illuminating indicators 176 can remain illuminated to show the charging level of the charging case assembly 100 and/or the vaporizer device 101, until the vaporizer device 101 is removed, disconnected, and/or the charging case assembly 100 moves to the closed position.
In some implementations, the illuminating indicators 176 can illustrate a fault state to indicate when there is an error reading the charging level of the battery 132 and/or the vaporizer, and/or the like. For example, in the error state, all of the illuminating indicators 176 can indicate that there is an error, such as by flashing a predetermined number of times.
In some implementations, the frame 170 can include one or more hinge recesses 153A. The hinge recesses 153A can be positioned along a portion of the upper surface of the frame 170. The hinge recesses 153A can extend into a sidewall of the frame 170. The hinge recesses 153A can be shaped and/or sized to receive at least a portion of the corresponding hinge housing protrusion 152. The hinge recesses 153A can be shaped, sized and/or positioned to align with the hinge recesses 153 of the lower housing 104. The hinge recesses 153A can include one, two, three, or four or more hinge recesses 153A to correspond to the number of hinge housing protrusions 152.
The frame 170 can include a charging cradle slot 172. The charging cradle slot 172 can include a recessed portion 172A and/or a raised portion 177. The raised portion 177 can be raised relative to the upper surface of the frame 170. The raised portion 177 can include a similar shape to a portion of the battery cover portion 174. For example, the raised portion 177 can have an upper surface and/or sidewalls extending between the upper surface and the upper surface of the frame 170. The raised portion 177 can be configured to be positioned above at least a portion of the retention mechanism 181 and/or the case electrical contacts 183 to secure the retention mechanism 181 and/or the case electrical contacts 183 between the frame 170 and the lower housing 104.
The charging cradle slot 172 can extend along at least a portion of a length of the frame 170 between the bottom end portion and the top end portion of the frame 170. The recessed portion 172A of the charging cradle slot 172 can be shaped and/or sized to allow the vaporizer device 101 to fit within and be secured within the charging cradle slot 172. In some implementations, the charging case assembly, such as the charging cradle slot 172 can be shaped and/or sized to retain one, two, three, or four vaporizers or portions of vaporizers. In some implementations, the length of the charging cradle slot 172 corresponds to the length of the vaporizer device 101. In some implementations, the length of the charging cradle slot 172 is longer than a length of the vaporizer device 101. Such configurations can allow the vaporizer to be easily placed within and/or removed from the charging case assembly 100.

The frame 170 can include an open side positioned opposite the hinge side. The frame 170 can include a recessed portion 178 positioned along the open side. The recessed portion 128 can extend inwardly towards the charging cradle slot 172 and/or downwardly from the upper surface along a portion of the hinge side towards the bottom side of the frame 170. The recessed portion 178 can be positioned at a rearward end portion of the open side of the frame 170 and/or can be positioned to align with the recessed portion 128 of the lower housing 104 The recessed portion 178 can be desirably shaped and/or positioned to allow a user to more easily open and/or close the charging case assembly 100, such as by using the user's thumb, finger, or hand.
The frame 170 can include a magnet receiver 180. As shown in at least
The cam 156 can be coupled with the cam rod 158. The cam 156 can be rotationally fixed to the cam rod 158 such that the cam rod 158 and the cam 156 can rotate about an axis of rotation. In some implementations, the cam rod 158 extends through the cam 156. In some implementations, the cam 156 and the cam rod 158 are integrally formed. In some implementations, at least a portion of the cam rod 158 can be positioned within the hinge rod slots 154 of the lower housing 104. In some implementations, at least a portion of the cam rod 158 and/or the cam 156 can be housed within the hinge housing protrusion 152 of the upper housing 102.
The cam 156 can include a cam extension portion 162. The cam extension portion 162 can extend from a side of the cam 156. The cam extension portion 162 can be configured to contact the switch 160. The cam extension portion 162 can include one or more surfaces. In some implementations, the cam extension portion 162 can include a first surface 162A, a second surface 162B, a third surface 162C, and/or a fourth surface 162D, or more surfaces.
The charging case assembly 100 can be opened by rotating the upper housing 102 relative to the lower housing 104 (or vice versa) about the axis of rotation. As the upper housing 102 rotates, the cam 156 and cam rod 158 can rotate in a first direction, such as a counter-clockwise direction. As the cam 156 rotates, the cam 156 can push the end portion of the switch 160 upwardly. Such movement can cause the switch 160 to pivot about a switch axis of rotation in a second direction, opposite the first direction, such as a clockwise direction. The end portion of the switch 160 can slide along an outer surface of the cam 156, such as at least a portion of the first surface 162A, the second surface 162B, and/or the third surface 162C.
In some implementations, the hinge assembly 150 can include a biasing member that can bias the switch 160 into the closed position. For example, the biasing member can bias the switch 160 into a position that is approximately parallel to the PCBA 185. In some implementations, the biasing member can include at least a portion of the cam 156, such as the cam extension portion 162. The bias of the switch 160 towards the closed position can desirably provide a frictional hinge. In some implementations, the bias of the switch 160 towards the closed position can desirably provide a friction-feel to the user as the user opens and/or closes the charging case assembly 100. For example, the hinge assembly 150 can enhance the durability of the charging case assembly 100 such that the charging case assembly 100 can be opened and closed a large number of times without failure. The hinge assembly 150 can desirably provide sufficient rigidity such that the case assembly may not be easily breakable when the charging case assembly 100 is in the opened position or the closed position.
When the charging case assembly 100 is in the opened position and/or the closed position, the switch 160 can activate an illuminating indicator 186 (shown in
The cam 156 can include a main body portion 161 and cam extension portion 162. The cam extension portion 162 can extend radially outward from a side of the cam 156. The cam extension portion 162 can be configured to contact the switch 160. The cam extension portion 162 can include one or more surfaces. In some implementations, the cam extension portion 162 can include a first surface 162A, a second surface 162B, and/or a third surface 162C, or more surfaces.
The charging case assembly 100 can be opened by rotating the upper housing 102 relative to the lower housing 104 (or vice versa) about the axis of rotation. As the upper housing 102 rotates, the cam 156 and cam rod 158 can rotate in a first direction, such as a counter-clockwise direction. As the cam 156 rotates, the cam 156 can push the end portion of the switch 160 upwardly and can cause the switch to pivot about a switch axis of rotation in a second direction, opposite the first direction, such as a clockwise direction. The end portion of the switch 160 can slide along an outer surface of the cam 156, such as at least a portion of the main body portion 161, the first surface 162A, and/or the second surface 162B.
In some embodiments, the hinge assembly 150 can include a biasing member that can bias the switch 160 into the closed position. For example, the biasing member can bias the switch 160 into a position that is approximately parallel to the PCBA 185 or angled relative to the PCBA 185 as shown in at least
When the charging case assembly 100 is in the opened position and/or the closed position, the switch 160 can activate an illuminating indicator 186 (shown in
The cam 156 can include a main body portion 161 and cam extension portion 162. The cam extension portion 162 can extend radially outward from a side of the cam 156. The cam extension portion 162 can be generally triangular, among other shapes. The cam extension portion 162 can be configured to contact the switch 160. The cam extension portion 162 can include one or more surfaces.
The charging case assembly 100 can be opened by rotating the upper housing 102 relative to the lower housing 104 (or vice versa) about the axis of rotation. As the upper housing 102 rotates, the cam 156 and cam rod 158 can rotate in a first direction, such as a counter-clockwise direction. As the cam extension portion 162 of the cam 156 rotates away from the switch 160, the switch 160 rotates in an opposite direction. For example, the switch 160 can rotate about a switch axis of rotation in a second direction, opposite the first direction, such as a clockwise direction. The end portion of the switch 160 can slide along an outer surface of the cam 156, such as at least a portion of the cam extension portion 162, such as a bottom surface.
In some implementations, biasing the switch 160 towards the opened position can desirably provide a frictional hinge. In some implementations, biasing the switch 160 towards the opened position can desirably provide a friction-feel to the user as the user opens and/or closes the charging case assembly 100. For example, the hinge assembly 150 can enhance the durability of the charging case assembly 100 such that the charging case assembly 100 can be opened and closed a large number of times without failure. The hinge assembly 150 can desirably provide sufficient rigidity such that the case assembly may not be easily breakable when the charging case assembly 100 is in the opened position and/or the closed position.
When the charging case assembly 100 is in the opened position and/or the closed position, the switch 160 can activate an illuminating indicator 186. The illuminating indicator 186 can flash, change colors, and/or brighten, or provide other indications that the charging case assembly 100 is in the closed position.
In some implementations, one or more of the magnets 169, 169B can have a magnetic force of approximately 235.5 Gauss, 276 Gauss, magnetic forces between 235.5 Gauss and 276 Gauss, and/or magnetic forces above 276 Gauss and/or below 235.5 Gauss.
In some implementations, the upper housing 602 can include a grip portion 608. The grip portion 608 can be positioned along at least a portion of an outer surface of the upper housing 602. The grip portion 608 can be positioned near one side of the outer surface of the upper housing 602. The grip portion 608 can extend along a length of the upper housing 602 such as adjacent a closing side 631 of the upper housing 602. The grip portion 608 can desirably provide a gripping surface that allows the user to more easily grasp the charging case assembly 600. The grip portion 608 can help to limit the charging case assembly 600 from slipping out of the user's hand in use. The grip portion 608 can form a surface that is coupled with the upper housing 602. In some implementations, the grip portion 608 is integrally formed with the upper housing 602. In some implementations, the upper housing 602 may not include the grip portion 608. In some implementations, the grip portion 608 has an enhanced appearance, such that the grip portion 608 enhances the aesthetics of the charging case assembly 600.

The vaporizer device 601 can include at least a first elongated side 690. When the vaporizer device 601 is coupled with the charging case assembly 600, the first elongated side 690 may be positioned against the base 107 of the cradle portion (e.g., vaporizer device slot 672) of the charging case assembly). The vaporizer device 601 can include one or more device charging contacts 684 configured to align with and electrically couple to the case charging contacts 674. The device charging contacts 684 can be positioned adjacent to a charging end 692 of the vaporizer device 601. The first elongated side 690 may be adjacent to the charging end 692 of the vaporizer device 601 and configured to be positioned against the base 107 of the cradle portion (e.g., vaporizer device slot 672) such that the first elongated side 690 aligns with the vaporizer device slot 672 and the device charging contacts 684 align with the case charging contacts 674.

As an example, if the charging case assembly 600 is plugged into a power source and is charging and/or a user shakes or taps the charging case assembly 600 to thereby activate the accelerometer, the microprocessor can activate one illuminating indicator 686 for every 25% battery charge of the charging case assembly 600. As such, if the case assembly has a 50% charge, two illuminating indicators 686 can be illuminated. In some embodiments, any remaining illuminating indicators 686 can turn on and off (e.g., blink) to indicate to a user that the charging case assembly 600 is charging. If the case assembly is fully charged, then all the illuminating indicators 686 can be activated. Such activation of any of the illuminating indicators 686, 687 can be for a predefined duration (e.g., approximately 2 seconds to approximately 15 seconds) before the illuminating indicators 686 are deactivated. Activation of the illuminating indicators 686, 687 for such a short duration preserves power and prevents from draining the battery or prolonging charging of the battery.
The upper housing 602 can be made out of a translucent material thereby allowing a user to see the illuminating indicators 686, such as one or more activated illuminating indicators 686 positioned along either the charging case assembly 600 or the vaporizer device 601. This can allow a user to simply shake or tap on the charging case assembly 600 without having to open the charging case assembly 600 to see the charging state or charging level of either the charging case assembly 600 or vaporizer device 601. In some embodiments, the charging case assembly 600 can include a switch that is activated upon opening the case assembly (e.g., pivoting the upper housing 602 relative to the lower hosing 604). Activation of the switch can result in some or all of the above-mentioned activation of one or more illuminating indicators 686, 687 to thereby inform a user of either the charging state or charging level of the charging case assembly 600 or vaporizer device 601. In some embodiments, the case assembly can include a microprocessor having or implementing logic such that when the charging case assembly 600 is plugged into a power source, the charging case assembly 600 can (as a result of being plugged into the power source) perform some or all of the above mentioned activating of one or more illuminating indicators to thereby inform a user of either the charging state or charging level of either the charging case assembly 600 or vaporizer device 601.
In some implementations, the illuminating indicators 686, 687 can illustrate an error or fault state to indicate when there is an error reading, such as a power connection issue, a battery failure, over-heating of the charging case assembly 600 or vaporizer device 601, or other errors associated with the charging case assembly 600 and/or vaporizer device 601. For example, in the error state, all of the illuminating indicators 686, 687 can indicate that there is an error, such as by flashing a predetermined number of times and/or in a predetermined color.
An example method associated with charging a vaporizer device using a charging case assembly consistent with one or more implementations described herein includes coupling the vaporizer device to a cradle portion of a lower housing of a charging case. The charging case can include an upper housing that is pivotably coupled to the lower housing for allowing the charging case to form an open configuration and a closed configuration. In addition, the method can include connecting a power source to at least one of a device battery associated with the vaporizer device and a case battery associated with the charging case. Furthermore, the method can include indicating at least one of a charging state and a charging level of the vaporizer device or the charging case. The indicating can include illuminating at least one indicator associated with the charging case or vaporizer device, and the at least one illuminated indicator can be viewable through the upper housing by a user when the charging case is in the closed configuration.
When a feature or element is herein referred to as being “on” another feature or element, it can be directly on the other feature or element or intervening features and/or elements may also be present. In contrast, when a feature or element is referred to as being “directly on” another feature or element, there are no intervening features or elements present. It will also be understood that, when a feature or element is referred to as being “connected”, “attached” or “coupled” to another feature or element, it can be directly connected, attached or coupled to the other feature or element or intervening features or elements may be present. In contrast, when a feature or element is referred to as being “directly connected”, “directly attached” or “directly coupled” to another feature or element, there are no intervening features or elements present.
Although described or shown with respect to one embodiment, the features and elements so described or shown can apply to other embodiments. It will also be appreciated by those of skill in the art that references to a structure or feature that is disposed “adjacent” another feature may have portions that overlap or underlie the adjacent feature.
Terminology used herein is for the purpose of describing particular embodiments and implementations only and is not intended to be limiting. For example, as used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and/or groups thereof. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items and may be abbreviated as “/”.
In the descriptions above and in the claims, phrases such as “at least one of” or “one or more of” may occur followed by a conjunctive list of elements or features. The term “and/or” may also occur in a list of two or more elements or features. Unless otherwise implicitly or explicitly contradicted by the context in which it used, such a phrase is intended to mean any of the listed elements or features individually or any of the recited elements or features in combination with any of the other recited elements or features. For example, the phrases “at least one of A and B;” “one or more of A and B;” and “A and/or B” are each intended to mean “A alone, B alone, or A and B together.” A similar interpretation is also intended for lists including three or more items. For example, the phrases “at least one of A, B, and C;” “one or more of A, B, and C;” and “A, B, and/or C” are each intended to mean “A alone, B alone, C alone, A and B together, A and C together, B and C together, or A and B and C together.” Use of the term “based on,” above and in the claims is intended to mean, “based at least in part on,” such that an unrecited feature or element is also permissible.
Spatially relative terms, such as “forward”, “rearward”, “under”, “below”, “lower”, “over”, “upper” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is inverted, elements described as “under” or “beneath” other elements or features would then be oriented “over” the other elements or features. Thus, the exemplary term “under” can encompass both an orientation of over and under. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. Similarly, the terms “upwardly”, “downwardly”, “vertical”, “horizontal” and the like are used herein for the purpose of explanation only unless specifically indicated otherwise.
Although the terms “first” and “second” may be used herein to describe various features/elements (including steps), these features/elements should not be limited by these terms, unless the context indicates otherwise. These terms may be used to distinguish one feature/element from another feature/element. Thus, a first feature/element discussed below could be termed a second feature/element, and similarly, a second feature/element discussed below could be termed a first feature/element without departing from the teachings provided herein.
As used herein in the specification and claims, including as used in the examples and unless otherwise expressly specified, all numbers may be read as if prefaced by the word “about” or “approximately,” even if the term does not expressly appear. The phrase “about” or “approximately” may be used when describing magnitude and/or position to indicate that the value and/or position described is within a reasonable expected range of values and/or positions. For example, a numeric value may have a value that is +/−0.1% of the stated value (or range of values), +/−1% of the stated value (or range of values), +/−2% of the stated value (or range of values), +/−5% of the stated value (or range of values), +/−10% of the stated value (or range of values), etc. Any numerical values given herein should also be understood to include about or approximately that value, unless the context indicates otherwise. For example, if the value “10” is disclosed, then “about 10” is also disclosed. Any numerical range recited herein is intended to include all sub-ranges subsumed therein. It is also understood that when a value is disclosed that “less than or equal to” the value, “greater than or equal to the value” and possible ranges between values are also disclosed, as appropriately understood by the skilled artisan. For example, if the value “X” is disclosed the “less than or equal to X” as well as “greater than or equal to X” (e.g., where X is a numerical value) is also disclosed. It is also understood that the throughout the application, data is provided in a number of different formats, and that this data, represents endpoints and starting points, and ranges for any combination of the data points. For example, if a particular data point “10” and a particular data point “15” are disclosed, it is understood that greater than, greater than or equal to, less than, less than or equal to, and equal to 10 and 15 are considered disclosed as well as between 10 and 15. It is also understood that each unit between two particular units are also disclosed. For example, if 10 and 15 are disclosed, then 11, 12, 13, and 14 are also disclosed.
Although various illustrative embodiments are described above, any of a number of changes may be made to various embodiments without departing from the teachings herein. For example, the order in which various described method steps are performed may often be changed in alternative embodiments, and in other alternative embodiments one or more method steps may be skipped altogether. Optional features of various device and system embodiments may be included in some embodiments and not in others. Therefore, the foregoing description is provided primarily for exemplary purposes and should not be interpreted to limit the scope of the claims.
