Description

Technical Field

[0001] This disclosure relates to an electronic smoking device, specifically, but not limited to, an electronic hookah device. Background Technology

[0002] WO 2015 / 172224 illustrates a prior art hookah device. This device includes an electronically heated chamber at its upper end, configured to receive a pouch containing smoking products. The user inhales through a hose, drawing air into the pouch. The air carries the smoking products, which pass through a duct into a water tank located at the lower end of the device. The smoking products pass through the water in the tank and through the hose to the user. Thus, the device functions similarly to a conventional hookah. However, the heating of the smoking products is electronically controlled and occurs within a specially designed oven that receives a custom-made pouch for containing the smoking products.

[0003] The inventors have identified certain problems with this prior art device. After a smoking cycle is completed, the pouch is removed to allow for replacement. The device in WO'224 includes a notch in the heating chamber that allows the user to lift the pouch out of the heating chamber. However, after using the device, both the heating chamber and the pouch may still be at high temperatures. This poses a significant risk of injury to the user. The notch is also relatively small, making pouch removal somewhat difficult.

[0004] WO 2019 / 238149 illustrates another prior art hookah device. In this example, a tight fit is required between the bag and the heating chamber. It is suggested that a chimney be used to push the bag out of the oven to allow for easy removal of the used bag after use. However, using the chimney as a bag actuator introduces complexity in sealing the chimney (i.e., ensuring that all smoke travels along the chimney and does not enter the device housing or otherwise escape from the chimney). Furthermore, the constant spring force used to bias the bag out of the heating chamber can be problematic and may not only hinder proper fit of the bag in the oven but also cause undesirable ejection of the bag in certain scenarios.

[0005] When a tight fit between the capsule and the heating chamber is required, such as for heating the capsule by conduction, it has been found that thermal expansion can cause the capsule to become stuck in the heating chamber in some cases. Waiting for the device to cool down before removing the capsule is not always practical.

[0006] The present invention aims to overcome or improve one or more of the above-mentioned problems. Summary of the Invention

[0007] According to this disclosure, a hookah device is provided, comprising: a heating chamber configured to heat a smoking product, the heating chamber having an opening; a receiver for receiving the smoking product in use within the heating chamber; a closure movable between a closed position and an open position, wherein in the closed position the opening is at least partially covered, and in the open position the opening is uncovered to allow access to the receiver; and a displacement mechanism operatively connected to the closure and configured to move the receiver relative to the opening in response to movement of the closure between the open and closed positions.

[0008] When the closure is closed, the displacement mechanism can move the receiver to engage with the heating chamber. The displacement mechanism can support the receiver relative to the heating chamber in a predetermined, aligned, and / or coaxial orientation during movement in the closed and / or open positions and / or between the closed and open positions.

[0009] In response to the movement of the closure to the open position, the displacement mechanism can disengage the receiver from the heating chamber, for example, prevent it from contacting the heating chamber.

[0010] The displacement mechanism may include a displacement member configured to engage or abut against a receiver in use to provide movement of the receiver. The displacement member may support or guide the receiver. The displacement member may move toward an opening.

[0011] The receiver can be received within the displacement member. For example, when positioned on the displacement member, the receiver can extend through the displacement member. The displacement member can at least partially surround the receiver in use. The displacement member can be annular or loop-shaped. The displacement member can engage the side of the receiver. The displacement member can engage the lower end of the receiver (i.e., the end opposite the opening in use).

[0012] The displacement member can engage the edge of the receiver.

[0013] The displacement member can be installed into the device via a guide. The displacement member can be restricted to a predetermined movement path. The movement path can be linear. The path can be toward or away from the opening. The path can be vertical in use.

[0014] The guide may include a handle or rod disposed on one of the lifting members or the base of the device. The handle / rod may be configured to be received by a sleeve, orifice, or channel on the other of the lifting members or the base of the device. The guide / sleeve may be secured to the lifting member.

[0015] The displacement member can be biased toward or away from the opening. The receiver can be biased toward, through, or away from the opening. The closure can be biased toward the open or closed position.

[0016] The bias can be provided by a biasing member. The biasing member can be disposed parallel to the guide. The biasing member can be mounted concentrically to the guide. The biasing member can operatively extend between the guide and the device base (e.g., sleeve / orifice). The biasing member can operatively extend between the shifting member and the device base. The biasing member can operatively be disposed between the closure and the base.

[0017] The displacement member can be operatively connected to the closure via a pivotable link. The link may include an arm or the like. The arm may be curved. The closure can be pivotally mounted to the device via a pivot. The pivotable link of the displacement member can be offset from the pivot of the closure, such that a linear movement of the displacement member occurs in response to rotational movement of the closure. The displacement member link can be pivotally connected to the displacement member. The displacement member can be operatively connected to the closure via two separate pivots. The pivots can be offset from each other.

[0018] The closure pivot may be disposed on the armature, such as an angled or U-shaped armature. The pivot may be disposed at one end of the armature and the closure may be attached to the armature at its opposite end. The displacement member link may be connected to a point on the armature spaced apart from the end of the armature (e.g., toward its apex). One of the displacement member link and the closure armature may be configured to be received within the other of the displacement member link and the closure armature.

[0019] The displacement member may include a surface configured to abut a flange / edge of the heating chamber or receiver in use. The surface may face an opening (i.e., positioned on the upper side of the displacement member). The surface may be circular / annular. The displacement member and the closure may be configured to clamp the flange / edge to form an hermetically tight seal therebetween (i.e., the bladder / heating chamber is located between the closure and the displacement member). The displacement member may include a tapered / angled surface abutting the adjacent surface. The lifting member may include a truncated conical shape.

[0020] For example, when the receiver engages with the heating chamber, the displacing member can disengage from the receiver. When the closure is closed, the displacing member can disengage from the receiver. During a portion of the movement range of the displacing mechanism, the displacing member can disengage from the receiver.

[0021] The movement of the closure member and the displacement member can be synchronous. The movement of the closure member and the lifting member can be asynchronous.

[0022] The receiver can be configured to protrude from the opening when the closure is in the open position, for example, beyond the plane of the opening. The edge / flange of the receiver can be configured to protrude from the opening when the closure is in the open position.

[0023] The receiver may include a capsule or container that is removably received within a heated chamber during use. The capsule or container may include a closure. The receiver may form an integral part of the heated chamber (e.g., the heated chamber may be displaced relative to an opening).

[0024] The device may include a release mechanism to selectively provide retention and / or release of the closure.

[0025] The release mechanism may include a latch. The latch may be disposed on one of the device base and the closure, and the engagement configuration may be configured to be selectively engaged by the latch on the other of the base and the closure. The latch may be biased to engage with the engagement configuration.

[0026] The release mechanism may include a manual actuator configured to disengage the latch from the engagement configuration.

[0027] The manual actuator can be operatively connected to the latch via the armature. A flexible biasing device can be provided between the armature and the base.

[0028] The resilient biasing device may include a foot configured to engage with the base. A spring portion may extend between the armature and the foot.

[0029] The arms and legs can be formed as one piece.

[0030] The armature can be pivotally mounted to the manual actuator and the base, such that linear movement of the actuator causes rotational movement of the latch.

[0031] The manual actuator may include a stop member configured to abut against the base or housing of the device to restrict its movement.

[0032] The armature may include two arms at an acute angle. One arm may form part of a latch, and the other arm may be operatively connected to a manual actuator. A biasing device may be mounted to one of the arms.

[0033] The pivot can be offset from the angled arm arrangement.

[0034] The manual actuator may include a button. The manual actuator may be biased to an unpressed state.

[0035] The enclosure may include an air inlet (e.g., to allow airflow into the heating chamber).

[0036] The release mechanism and / or shifting mechanism may be electronically controlled. The release mechanism and / or shifting mechanism may include a motor to achieve its movement.

[0037] The device may include sensors to detect the actuation of the opening and / or release mechanism of the closure.

[0038] Heating of the heating chamber can be controlled by a controller. The controller can operatively communicate with sensors. The controller can be configured to limit or prevent heating when it detects the opening of the closure and / or actuation of the release mechanism.

[0039] The device may include an electronically heated device. The heating chamber may be heated via a heating element. The device may be heated via combustion.

[0040] According to a further aspect, a hookah device is provided, comprising: a heating chamber configured to heat a smoking product therein and accessible via an opening in the device; a closure movable between a closed position and an open position, wherein in the closed position the opening is at least partially covered and in the open position the opening is not covered; and a release mechanism selectively providing retention and / or release of the closure.

[0041] The closure and / or device may carry a seal such that the closure seals against a corresponding portion of the device. The seal may be annular. Air openings in the closure may be radially located inside the seal, such that the seal seals around a flow path into the device.

[0042] The device may include a housing or enclosure, for example, a housing or enclosure surrounding the head of the device and / or surrounding a heating chamber, which may define an outer wall or surface of the device. The closure may be recessed relative to the housing or its outer surface when closed. The outer surface of the closure in the closed position may be substantially flush with the outer surface of the housing.

[0043] Where feasible, any optional or preferred features described with respect to any aspect of the invention or defined in any of the appended claims may be applied to any further aspects.

[0044] The displacement mechanism and / or displacement member may be referred to herein as lifting mechanism and lifting member, respectively. However, it should be understood that such lifting member can, as needed, displace the receiver relative to the heating chamber and / or relative to the vertical or horizontal axis in any suitable direction.

[0052] Figure 7 An exploded view of the pop-up mechanism is shown. Detailed Implementation

[0053] Figure 1 and Figure 2 The image shows a hookah device 2. Typically, device 2 is configured to heat the smoking product to allow the user to inhale it. The smoking product can come in any suitable form. The smoking product can include tobacco-based products, such as hookah tobacco. The smoking product is housed in a pouch. The pouch is configured to be heated by device 2. Device 2 can be portable or handheld.

[0054] The device includes a head 4. The head 4 is configured to receive a capsule of smoking product during use. The device 2 typically receives the capsule on or within the head 4. The head 4 is positioned at the upper end of the device during use.

[0055] The head 4 comprises a disc-shaped or lens-shaped / convex shape, for example, which is generally circular in a plane and curved in cross-sectional profile at its perimeter. The head 4 is the uppermost part, and in the example shown, the head 4 is wider than the neck 12 of the device, which extends below the head toward the base 6.

[0056] Device 2 includes a base 6. The base is provided with a reservoir, container, or tank for cooling liquid 8 (e.g., water). The base 6 is generally bulbous or spherical. In this example, the base 6...

[0057] The base 6 includes a flat lower surface 10 to ensure that the device 2 stands upright on the support surface during use. The lower surface 10 may include a gripping member (e.g., a rubber pad or the like). The reservoir of the base 6 includes a transparent material. This allows the user to ensure the water level is correct and / or to see the smoking product entering the water during use. The reservoir may include glass. The reservoir may include a transparent polymer, such as one or more of acrylic (PMMA), butyrate, polycarbonate, PET, or PETG.

[0058] The neck 12 connects the base 6 and the head 4. The neck 12 tapers towards the head 4. The base 6 and the neck 12 may be pear-shaped or teardrop-shaped. At the junction between the head 4 and the neck 12, the head 4 is wider than the neck 12. Therefore, the head 4 extends outward from the neck. Thus, the head 4 provides a flange or edge.

[0059] Neck 12 provides a handle for the user, such as a part of the device that can be firmly gripped. Neck 4 may include a handle or the like. The handle may include a high-friction or irregularly shaped material (e.g., rubber) or may have the same material as the rest of the neck / head. Neck 12 contains an electronic compartment, which will be described in detail later.

[0060] The head 4 and neck 12 may be opaque, i.e., different from the reservoir at the base.

[0061] The head 4 and neck 12 are detachable / separable from the base 6. Therefore, the electronics compartment can be separated from the base 6. This allows access to the reservoir to add / remove coolant. The junction between the lower end of the neck 4 and the base 6 may include threads, bayonet, or other suitable attachment structures.

[0062] The cross-section of device 2 is typically circular (i.e., when viewed in a plane). However, it is understood that the device may include any suitable cross-sectional shape, such as a curved or polygonal shape. The cross-sectional shape or width may vary along the axial length of device 2. Device 2 includes a housing of thermally insulating and / or electrically insulating material. Typically, the housing of the device comprises a polymer / plastic material.

[0063] Hose 14 is connected to device 2. Hose 14 is removably attached to the device, for example, at an end of the hose with a connector configuration. This allows cleaning of hose 14 and / or removal of hose 14 for storage. Hose 14 is received through an opening or slot 16 in neck 12. Preferably, an airtight / sealed connection is formed.

[0064] Therefore, the hose 14 is fluidly connected to the interior of the base 6, i.e., in communication with the air space inside the reservoir. The hose 14 is mounted via an interference fit or a friction fit. The hose connector 18 and / or the orifice 16 may comprise a high-friction material (e.g., rubber). The connector 18 tapers toward one end. In other embodiments, the hose may be mounted to the device 2 via one or more of fasteners, latches, threads, recessed / stop arrangements, clamps, or other suitable devices.

[0065] In some embodiments, the hose 14 may be connected to the device 2 via a snap-fit ​​or plug-in engagement. Typically, a resiliently biased stop is provided on the device 2 or connector 18. The stop is configured to snap-fit ​​into a corresponding recess / groove on the connector 18 or device 2. The stop may be biased via a spring or the like. In some embodiments, the stop may comprise an arcuate or annular ring. The stop is received within an arcuate / annular recess of a corresponding shape.

[0066] The hose 14 is flexible. The hose 14 may include a flexible polymer. The hose 14 includes a nozzle 20. The nozzle 20 is removable / detachable from the hose 14. The nozzle 20 may include a removable cover or the like (e.g., to improve hygiene among multiple users).

[0067] The head 4 includes a closure or cover 22 to provide an opening thereto. This allows insertion of a smoking product pouch containing the smoking product. The cover 22 is pivotally / hingedly attached to the device 2. The cover 22 is located at the upper end of the device 2. Thus, the smoking product is loaded into the upper end of the device. The cover 22 has a spherical / circular shape. The cover 22 is movable between a closed position where the opening is covered (i.e., closed) and a second position where the opening is not covered (i.e., open).

[0068] In the closed position, the cover 22 is typically flush with the surrounding portion of the head 4. In the open position, it is at an angle to the plane of the opening, typically a right angle or an obtuse angle to the plane of the opening.

[0069] like Figure 3 As shown, a heater 24 in the form of a heating chamber is installed within the device 2. The heater 24 is installed within the electronic compartment 12 and / or the head 4. The heater 24 is configured to receive the capsule. During use, the heater 24 heats the capsule to evaporate or otherwise disperse one or more components of the smoking product.

[0070] The wall 26 of heater 24 is shaped to conform to the shape of a capsule. Therefore, the capsule forms a tight fit with the heater during use, for example, around its perimeter. The heater can be defined as an oven or other heating chamber arranged to substantially surround the capsule for heating through its walls.

[0071] Wall 26 has a concave / conical shape. Typically, wall 26 is trapezoidal or truncated conical.

[0072] The heater 24 surrounds or encloses the bladder during use. Therefore, the heater 24 forms a heating chamber or cavity. The cover 22 closes the heating chamber 24. Thus, the cavity / room is sealed / closed during use. One or more heating elements may be disposed on, within, and / or integrally formed with the wall 26 of the heating chamber 24. The heating chamber 24 comprises a thermally conductive material (e.g., metal). Therefore, during use, heat passes through the wall 26 of the heating chamber 24 into the bladder.

[0073] In other embodiments, the heating element is displaced from the heating chamber. For example, the heating element may surround or enclose the heating chamber. The heating element may project or direct light or airflow into the heating chamber.

[0074] Typically, the heating device comprises a resistive element (i.e., heated by a current flowing through the resistive element). The resistive element may be formed directly on or integrally with the wall 26 of the heating chamber. However, the heating chamber 24 and / or the capsule can be heated by any suitable method, such as one or more of the following: induction heating; microwave heating; infrared heating; convection heating (e.g., the heating element is displaced away from the wall 26 of the heating chamber); electronically controlled combustion heating (e.g., using gas or other fuels); and / or oil heating. An electrically controlled heating device is preferred, allowing for precise control of the heating of the capsule.

[0075] As in Figure 1 The best visible part is the cover 22, which includes the air inlet 28.

[0076] Therefore, the heating chamber 24 includes one or more air inlets 28 to allow air to enter the heating chamber 24. This air then mixes with the evaporated product within the heating chamber 24. The air inlets 28 allow air to pass through the cover 22 (i.e., inlets 28 provide a passage through the cover 22). In this example, the air inlets 28 are located in the central portion of the cover 22. Therefore, the air inlets 28 are positioned above the heating chamber 24 / bag during use.

[0077] Air inlet 28 may include a plurality of openings or perforations, such as an array of through holes. Air inlet 28 may include a grille or mesh to prevent debris from entering inlet 28.

[0078] Heater 24 may be controlled by electronics in electronics compartment 12 (e.g., via a heater controller). Electronics may include a microcontroller / microprocessor, memory (volatile and / or non-volatile), and / or electrical regulation circuitry (e.g., a power limiter and / or a controller). Electronic compartment 12 includes any suitable components for providing heating to heater 24.

[0079] Device 2 may include a communication interface. The communication interface may be wired and / or wireless. A wired interface may include a USB or Ethernet interface (e.g., a USB port). A wireless interface may include an interface for communication via one or more of Wi-Fi, Bluetooth, NFC, infrared, and cellular (e.g., GSM, 3G, 4G, 5G, etc.). Device 2 may include any suitable antenna for wireless communication.

[0080] The device includes a power source. This power source can supply power to heater 24 and / or heater controller. The power source can be AC-powered (e.g., via a wire or the like). Alternatively or additionally, the power source includes battery 35 or other onboard energy storage. The battery can be removable and / or rechargeable. Power transmission to device 2 for use or recharging can be wired or wireless.

[0081] A power switch 30 or similar device can be provided. Therefore, the device 2 and / or heater 24 can be manually controlled (e.g., turned on / off). The switch may include a push-button switch or a touch interface.

[0082] Device 2 includes an indicator 32. The indicator includes a light (e.g., an LED) or other visual indicator. Indicator 32 can indicate the status of the device, such as the power level of heater 24 and / or its temperature. Indicator 32 includes a series of lights. Therefore, the number of lights illuminated can indicate the power level / temperature of heater 24 or its temperature. In some embodiments, indicator 32 may include a display or the like. The display may be interactive (e.g., a touchscreen). The indicator can indicate the readiness status of the device for use.

[0083] The heating chamber 24 is operatively connected to the cooling / water reservoir 6 via a conduit 34. Therefore, the heating chamber 24 and the reservoir 6 are in fluid connection. The conduit 34 provides a cylinder, tube, or passage. The conduit 34 is typically sealed to / against the heating chamber 24 to prevent air leakage. The conduit 34 extends into the reservoir 6. Therefore, the conduit 34 extends into the cooling fluid / water during use. The conduit may include a one-way valve to prevent backflow into the heating chamber 24.

[0084] The conduit 34 passes through the electronics compartment / neck 12. Therefore, the conduit 34 seals or isolates the heating chamber 24 and / or the product evaporating from the electronics compartment 6 to prevent contamination. The electronics compartment includes a cavity or hollow section for accommodating the conduit 34. The cavity is fluidly isolated from the heating chamber 24 and / or the reservoir 6.

[0085] One or more batteries surround or enclose the conduit 34. This provides a compact configuration. Typically, the batteries consist of cylindrical battery cells arranged in a circular pattern. These battery cells are arranged around the circumference of the conduit 34. Between four and eight battery cells can be used.

[0086] As can be seen, the conduit 34 is wider in the region passing through the neck (i.e., the region directly below the heater 24). The conduit is narrower in the region extending into the base 6 (i.e., into the water tank). A necking may be provided near the lower end of the neck (e.g., at the junction with the water tank).

[0087] The conduit 34 includes a diffuser 36 arrangement. The diffuser 36 is typically located at the end 38 of the conduit 34. The diffuser may include multiple orifices or the like for allowing fluid / vapor to flow from the conduit into water. The end 38 of the conduit 34 may be closed / sealed (i.e., allowing all gas / vapor from the conduit to pass through the opening of the diffuser). Alternatively, the end 38 of the conduit 34 may be open. The end 38 may be narrowed or otherwise contracted.

[0088] In use, air enters through air inlet 28 and then into heating chamber 24. The air then carries evaporated smoking product within heating chamber 24. The air / steam then travels along duct 34 and reaches the coolant in reservoir 8. The air and / or steam is cooled and / or filtered as it passes through the coolant as bubbles. The air / steam then bubbles upwards through the coolant and enters hose 20. Typically, the airflow is provided by negative pressure from the user (i.e., at mouthpiece 20).

[0089] When using capsules, porous / perforated walls are provided on the capsule to allow air to enter and / or allow evaporated product to escape from it. Porosity can be provided by orifices or perforations on one or more sides of the capsule (usually the opposite top and bottom). The diameter of the orifices is typically less than 5 mm.

[0090] Head 4 Figure 4 The image shows this in more detail. The head 4 includes a housing 40 configured to surround an interior portion of the head 4. The housing includes an upper housing 40A. The upper housing 40A is configured to surround a cover 22. The upper housing 40A includes an opening or aperture 42 in which the cover 22 is received (see image). Figure 1 The lid is flush with the upper housing when closed.

[0091] Therefore, orifice 42 allows access to heating chamber 24.

[0092] The upper housing 40A may be generally annular. The upper housing 40A abuts against the lower housing 40B. The lower housing 40B may be conical or funnel-shaped. The lower housing engages with the upper end of the housing 43 of the neck 12.

[0093] The widened shape of the head allows for an annular space within the head surrounding the orifice 42 and / or the heating chamber 24. This space can be used to mount additional components within the head, such as electronic and / or mechanical parts.

[0094] A base frame 44 is disposed within the head 4. The base frame 44 is configured to support various components within the head 4. The base frame 44 may support the heating chamber 24 and / or the capsule ejection mechanism 46, which will be described in detail later. It will be understood that the base frame 44 may form part of the housings 40, 42 or any other support structure for the device 2.

[0095] An illumination arrangement 48 is provided. The illumination arrangement 48 is configured to illuminate the head 4. The illumination arrangement 48 is configured to illuminate the outer edge of the head 4. The illumination arrangement 48 includes a circular or annular shape. A portion of the upper housing 40A adjacent to the illumination arrangement 48 may be transparent / translucent. The illumination arrangement 48 includes a plurality of LEDs. The LEDs are circumferentially spaced around the illumination arrangement 48. The illumination arrangement 48 can be used for general illumination of the head and / or can provide visual indications related to the operation of the device, such as the type of visual indication described above with respect to indicator 32.

[0096] An antenna or other wireless receiver (not shown) may be disposed in the head. The antenna / receiver is operatively connected to a wireless communication interface. This interface may include one or more of NFC / RFID, Bluetooth (RTM), Wi-Fi, or other short-range interfaces. The wireless interface may allow communication with remote devices (e.g., mobile (cellular) phones).

[0097] The second wireless interface can be configured to operatively connect to the capsule 50 and / or a data carrier thereon. For example, the second interface can extract data related to the smoking product and / or its heating profile. The second interface may include one or more of NFC / RFID, Bluetooth (RTM), Wi-Fi, or other short-range interfaces. An antenna may be disposed on or adjacent to the heating chamber 24. In some embodiments, the first and second wireless interfaces may be provided with the same or a common interface.

[0098] Capsule ejection mechanism 46 Figures 5-7 The details are described below. The ejection mechanism 46 includes a release mechanism 52. The release mechanism 52 is configured to release the cover 22 to allow the cover to rotate about its hinge for selective access to the heating chamber 24. The release mechanism 52 is also used to lock the cover 22 in a closed position. This ensures that the cover 22 remains closed during heating of the bladder 50.

[0099] The release mechanism includes a manual actuator 54. The manual actuator 54 provides manual actuation of the release mechanism 52, thereby opening the cover 22. The manual actuator 54 includes a button or the like. The button 54 is received within an aperture 56 in the housing 40A and / or the base 44. The aperture 56 may include sidewalls or guides to guide or otherwise constrain lateral movement of the button 54. Thus, the manual actuator 54 can move linearly between a depressed state and an undepressed state. A stop member 58 is configured to retain the actuator 54 within the housing 40A.

[0100] A latching mechanism is provided to engage the cover 22. The latching mechanism includes a latch 62 configured to engage a corresponding configuration 64 on the cover 22. The distal end of the latch 62 includes a tapered / angled surface. This allows the cover configuration 64 to pass over it during cover closure. Opposite sides of the latch 62 include steps / protrusions to retain the cover configuration 64. Therefore, the latch 62 includes a barbed or arrowhead-shaped arrangement. The cover configuration 64 includes a step or flange for abutting the step when latched.

[0101] The latching mechanism 60 is mounted to the base frame 44 via a pivot 66. The pivot 66 includes a shaft / pin or the like. This shaft is received within an aperture in the base frame 44. However, it will be appreciated that any suitable component can be provided; for example, the base latching mechanism 60 may include an aperture configured to receive a shaft on the base frame 44. The pivot 66 allows the latch 62 to rotate toward / away from the cover configuration 64. This allows the cover configuration 64 to pass over the latch 62 during closing and allows it to disengage completely during opening.

[0102] The latching mechanism includes an arm 68 configured to engage the manual actuator 54 (in Figure 6 (Best visible in the middle). Therefore, the manual actuator can accordingly move the latch 62. Arm 68 includes an engagement configuration configured to be received within the manual actuator 54. The engagement configuration includes a plurality of outwardly extending arms 70 (see...). Figure 7 Arm 70 extends in the lateral direction. Arm 68 is therefore T-shaped. Manual actuator 54 includes a notch 72 for receiving arm 70. Arm 70 / notch 72 prevents unwanted relative movement of arm 68 relative to the actuator. Arm 70 can be pivotally or loosely received within the notch to allow relative rotation therebetween. This allows linear movement of actuator 54 to be transmitted as rotational movement of latching mechanism 60.

[0103] The actuator arm 68 is angled relative to the arm 74 of the latch 62. This angle is acute. Therefore, the latching mechanism is V-shaped. The pivot 66 is offset from the apex 76 of the V-shape. This provides greater leverage to the latching mechanism 60. A web 78 extends between the arms 68, 74 and the pivot 66 to provide increased structural strength.

[0104] The manual actuator 54 is biased to the unpressed state. The latching mechanism 60 is correspondingly biased to the locked position (i.e., the latch 62 is biased to engage with the cover configuration 64). A biasing mechanism 80 is configured to bias the actuator 54 / latching mechanism 60. The biasing mechanism 80 is operatively disposed between the latching mechanism 60 and the base frame 44 (see...). Figure 4 The biasing mechanism includes a foot 82 configured to abut against the base frame 44. Therefore, the foot 82 is shaped to conform to the base frame 44. The foot 82 includes an angled tip 84. This provides a stop and ensures that the foot 82 is restrained within the base frame.

[0105] A spring member 86 extends between the foot 82 and the latching mechanism 60. The spring member 86 is mounted to the actuator arm 68. A portion of the spring 86 forms an acute angle with the actuator arm 68. The spring 86 also forms an acute angle relative to the foot 82. Therefore, the biasing mechanism 80 includes a Z-shape. The spring member 86 can be cut from the foot 82. Therefore, the foot 82 and the spring member 86 are integral.

[0106] The spring member 86 can be formed by stamping the foot 82 to partially separate the spring 86, and then deforming the spring member 86 to form an angle away from the foot 82. The spring member 86 is disposed between the two parts of the foot 83 (e.g., to provide a sled-like arrangement). The angled spring member 86 is oriented laterally toward the cover 22 (i.e., toward...). Figure 5 The latch 62 is biased on the right-hand side. This ensures a tight connection between them. The spring member 86 simultaneously provides a biasing force in the upward direction (i.e., perpendicular to the lateral direction) to bias the actuator 54 toward the unpressed state.

[0107] It is understood that the biasing mechanism 80 can be provided by any suitable biasing arrangement. For example, the biasing mechanism may include one or more of the following: a coil spring; a leaf spring; a resiliently deformable material; or a gas spring. In some embodiments, the manual actuator 54 and the latching mechanism 60 are biased by independent biasing devices.

[0108] Release mechanism 52 may include any suitable arrangement to provide selective release / retention of cover 22. For example, release mechanism 52 may include one or more of the following: a recessed / stop arrangement; a sliding shaft or rod; or a rotating arm or plate. Manual actuator 54 may include any suitable form to affect release mechanism 52 accordingly. Manual actuator 54 may include one or more of the following: a handle; a linear switch; a push rod; a rocker arm switch; a rotatable switch. In some embodiments, actuator 54 is disposed on cover 22, and latch 62 engages with a configuration mounted to base 44.

[0109] The ejection mechanism 46 includes a lifting mechanism 88 configured to lift the bladder (e.g., when the bladder is hot or cold) out of the heated chamber 24 in response to the opening of the cover 22.

[0110] Reference Figure 7 The cover 22 includes a pivot 90. The pivot 90 is mounted to the base 44 or other parts of the head 4. The pivot 90 includes a shaft configured to be received in an aperture or the like in the base 44 / head 4. It will be understood that any suitable rotating mechanism, such as a bearing, may be provided. In some embodiments, the pivot 90 provides an aperture to receive a shaft on the base 44 / head 4.

[0111] A pivot 90 is provided on an arm 92. The arm 92 is curved or U-shaped. The pivot 90 is located at one end of the arm 92. The opposite end of the arm is connected to the cover 22. The arm 44 includes the entire portion of the cover. The apex of the arm 92 points downward (i.e., towards the storage tank 6 in use).

[0112] The ejection mechanism 46 includes a lifting member 94. The lifting member 94 is configured to be received beneath the pouch 50 and / or its edge 96. Thus, as the lifting member 94 rises, the pouch 50 rises accordingly. The lifting member 94 includes an opening 98 to receive the pouch 50. Therefore, the lifting member 94 is annular or ring-shaped. The lifting member 94 includes a flat upper surface 100 to support the pouch edge 96. In use, the edge 96 can be clamped between the cap 22 and the lifting member 94. A tight connection can be provided between them to help prevent air loss.

[0113] The heating chamber 24 includes an edge / flange 102. Therefore, the lifting member 94 is positioned between the bladder edge 96 and the heating chamber edge 102 during use. The lifting member 94 may abut the heating chamber edge 102. A seal can be formed between them. This helps reduce air loss.

[0114] The edge 96 of the pouch 50 is generally wider than the upper surface 100 of the lifting member 94. This allows the user to reach below the edge 96 to lift the pouch using their fingers or tools. The surface 101 adjacent to the upper surface slopes towards the top and tapers away from the upper surface 100 to allow greater access to the area below the edge 96.

[0115] In this embodiment, the lifting member 94 completely surrounds the pouch 50. This provides optimal support. In other embodiments, the lifting member 94 only partially surrounds the pouch 50 (e.g., in a crescent shape). In some embodiments, the lifting member may engage the pouch 50 only at discrete locations. For example, the lifting member 94 may include tabs or flanges for engaging the pouch 50.

[0116] In some embodiments, the lifting member 94 may engage the sidewall 104 of the pouch 50. This leaves a gap between the upper surface 100 of the lifting member 96 and the edge 96 of the pouch, allowing for easy gripping by a user. In some embodiments, the lifting member 96 may engage the bottom surface 106 of the pouch 50. For example, a portion of the lifting member 94 is received within the heating chamber 24. Alternatively or additionally, the lifting member 94 is connected to or integrally formed with the heating chamber 24. Thus, the heating chamber 24 may be movable to eject the pouch 50.

[0117] The lifting member 94 is operatively connected to the cover 22 via a pivot 108. The pivot 108 includes a shaft configured to be received within an aperture 110 in the arm 92. It will be understood that the connection between the cover 22 and the lifting member 94 can be provided by any suitable rotatable connector. For example, the shaft can be provided on the arm 92. The pivot 108 can snap-fit ​​into the aperture 110.

[0118] The pivot point 110 on the arm is offset from the pivot point 90 between the cover 22 and the base frame 44. Therefore, when the cover rotates, the pivot point 110 undergoes a linear movement in the upward direction, thereby raising the lifting member 96. The pivot point 110 is spaced apart from both ends of the U-shaped arm 92. The pivot point 110 may be located between the apex of the arm 92 and the end of the arm 92 connecting to the cover 22.

[0119] A lifting member pivot 108 is provided on the arm or connecting rod 112. The pivot is located at the end of the arm 112. The arm protrudes away from the lifting member 94. The arm 112 is curved. The arm 112 is pivotally mounted to the lifting member 94. The arm 122 is pivotally mounted via a shaft / hole arrangement 114 (see...). Figure 5 This ensures that the lifting member 94 remains in the same orientation during lifting. The lifting member 94 is connected to the closure 22 via two separate pivots.

[0120] The lifting member arm 112 is received within the cover arm 92. Therefore, the cover arm 92 includes a cavity for receiving the lifting member arm 112. This allows the arms 92, 112 to pivot freely relative to each other.

[0121] The lifting member 94 includes a guide 116 to ensure that the lifting member remains in the same orientation during lifting. The guide 116 includes a rod or handle. The guide projects downward (i.e., toward the neck 12) during use. The guide 116 may extend into the neck 12 (see...). Figure 4Guide 116 is received within second guide 118. This constrains guide 116 in the lateral direction. Therefore, guide 116 can move only in its axial direction (i.e., in the vertical direction during use). This prevents the lifting member 94 from rotating. Second guide 118 is secured to any suitable part of device 2, such as base 44, head housing 40, or neck housing 42.

[0122] The lifting member 94 is biased into an elevated or extended position. This biasing is provided by a biasing device disposed on the guide 116. The biasing device includes a spring 120. The spring 120 is located between the second guide 118 and a stop member 122 on the guide 116. The stop member 122 includes a flange or edge. The flange / edge is disposed at the end of the guide 116. This biases the guide 116 toward the elevated position (i.e., upward), thereby correspondingly biasing the lifting member 96. This, in turn, biases the cover 22 toward the open position. The spring 120 passes through the lifting member 64 (i.e., via an opening therein). The spring 120 is concentrically mounted to the guide 116 (i.e., the guide 116 is received in the spring 120). In some embodiments, the spring 120 may abut against the underside of the lifting member 94.

[0123] In an alternative embodiment, the biasing member may be configured to bias the cover 22 toward the open position. Consequently, the lifting member 94 is biased toward the opening. This biasing member may include a torsion spring or the like.

[0124] When the cover 22 is fully open and the lifting member 94 is in the fully raised position, the pouch 50 (e.g., edge 96) is positioned in a location easily accessible to the user. For example, the pouch may protrude above the uppermost point of the upper housing 40A. Typically, the lifting member partially protrudes through the opening, making its upper surface 100 and edge 96 accessible.

[0125] Understandably, the height of the lifting member 94 can be optimized by adjusting the offset between the pivot points 90 and 110 on the cover arm 92. The movement of the lifting member 94 is smooth / continuous with the movement of the cover 22 (i.e., an incremental movement of the cover 22 results in a corresponding incremental movement of the lifting member 94). Therefore, the movement of the cover 22 and the lifting member 94 / bag 50 is synchronized.

[0126] In some embodiments, the movement of the cover 22 and the lifting member 94 / bag 50 can be asynchronous. For example, the lifting member 94 may move to the fully raised position only when the cover 22 is fully open. Alternatively, the movement of the lifting member 94 may be restricted until the cover 22 rotates to a predetermined position. This may cause the lifting member 94 / bag to "pop up." However, it is understood that smooth movement of the bag 50 is desired to prevent the bag 50 from fully popping out of the device 2.

[0127] In some embodiments, the opening of the cover 22 and / or the raising of the lifting member 94 can be provided by an actuator. For example, a motor can be configured to drive rotation of the cover 22 and / or linear movement of the lifting member 94. For example, a motor can provide axial movement of the guide 116. The motor can be electronically controlled. This allows for automatic opening / closing of the cover 22.

[0128] In some embodiments, the release mechanism 52 may be implemented via an actuator / motor. For example, a power actuator may cause the latch 62 to move into / out of engagement of the engagement configuration 64. The release mechanism 52 may be electronically controlled. For example, once the smoking process has been completed, the release mechanism 52 is actuated to automatically open the cover 22.

[0129] In some embodiments, the release mechanism 52 may not be provided. The user can directly engage the cover 22. The cover 22 may include a handle, etc. The cover 22 can be biased to a closed / in position without the use of a latch. It will be appreciated that the lifting mechanism 88 can be held as previously described.

[0130] Sensors may be provided to detect the operation of the release mechanism 52 and / or the opening of the cover 22. For example, the sensor may detect the position of the cover 22 and / or the lifting member 94. Sensors may be provided to detect the actuator of the manual actuator 52. The sensors may include pressure sensors, contact sensors, or light sensors. When the opening of the cover 22 or the operation of the release mechanism 52 is detected, the heating controller may reduce or stop the heating of the heating chamber 24.

[0131] In this embodiment, the bag 50 includes a lid (not shown). Therefore, the bag is essentially closed. The lid includes an air inlet or opening (e.g., a perforation). In other embodiments, the bag 50 may include an open container (i.e., without a lid). The container may be cup-shaped or tray-shaped.

[0132] Although this embodiment has been described in the context of electronically heated hookahs, it will be understood that such features can be used in conventionally heated hookahs (e.g., those heated with charcoal or the like). In some embodiments, a pouch may not be provided and the smoking product may be placed directly into the heating chamber. In some embodiments, multiple hoses 14 and / or mouthpieces 20 may be provided. Thus, multiple users can use the device simultaneously.

[0133] Smoking products can include tobacco-based products.

[0134] Operation of the present invention

[0135] First, the cover 22 is opened and the heating chamber 24 is empty. The user places the sachet onto the lifting member 96, and the body of the sachet passes through the opening 98 in the lifting member 96. The sachet 50 is partially received within the heating chamber 24.

[0136] The user closes cover 22 by manually pressing it down. Cover 22 rotates about pivot 90, thereby moving lifting member 94 downward. Lifting member 94 is maintained in the correct orientation via guide 116 and moves against the bias of spring 120. Thus, the user closes cover 22 against the bias of spring 120.

[0137] Closing the lid lowers the capsule into the heating chamber in the correct alignment.

[0138] The engagement configuration 64 on the cover 22 engages the tapered edge of the latch 62. This pushes the latch 62 out of the path of the engagement configuration 64. Once the engagement configuration has passed the latch 62, the latch 62 snaps onto the engagement configuration 64, thereby providing retention of the engagement configuration. The latch 62 is biased to engage with the engagement configuration 64, thereby holding the cover 22 in the closed position.

[0139] In the closed position, the capsule 50 is received within the heating chamber 24 and is generally made in contact with the heating chamber. The user then heats the capsule and inhales the smoking product.

[0140] Once the user has finished, the heating chamber 24 is de-energized. The user presses button 54 against the bias of latch spring 86. Latch 62 rotates away from the engagement configuration, and cover 22 rotates freely. The bias of guide spring 120 moves the guide upward, thereby raising the lifting member 94 and cover 22. The pouch 50 rises away from the heating chamber 24, and the user can easily remove the pouch.

[0141] The arrangement of the hinges and / or pop-out mechanisms disclosed herein can be adapted to accommodate user "force" on the mechanism. For example, a user might attempt to force the lid closed, even when the pouch is not properly inserted or when another object / component is unintentionally caught under the closure. In such cases, forcing the closure could damage the closure mechanism. Therefore, selective release points are proposed within the aforementioned mechanism, allowing excess force on the mechanism to be released. For example, one of the joints or components (e.g., at shaft 114 or between other pivoting components) can translate, slide, remove, or "pop up" from its engaged position under excessive load. The removed component can return to its operating position when the closure moves in the opposite direction. Thus, the hinges or shafts in this pivoting mechanism can provide release points for excessive load and help prevent unintentional damage to the mechanism by the user.

[0142] This arrangement allows for easy removal of the pouch from the device. This helps reduce the chance of injury to the user. In response to the opening of the lid, the pouch automatically rises from the device. This provides a simple and effective way to eject the pouch. The lid can be securely closed, and this arrangement provides a robust and easy-to-operate method for opening the closure.
