Description

Technical Field

[0001] The present invention relates to an aerosol generating device including a cover that can be rotated from an open position to a closed position and vice versa.

Background Art

[0002] Aerosol generating devices or electronic cigarettes are currently the mainstream products that simulate conventional paper cigarettes. There are many types of aerosol generating devices, one of which has an operating method of heating a tobacco product to generate an aerosol without burning the tobacco. These so-called non-combustion heating type (HNB) devices are becoming increasingly popular. Non-combustion heating type devices generally have an opening for inserting an aerosol generating article, which provides access to a heating system for heating the aerosol generating article. These openings that enable the insertion of the aerosol generating article are generally sealed by a lid, often in a sliding arrangement. These sliders are components that span the opening for inserting the aerosol generating article and are stacked on top of the device. The sliders often not only bulge but also allow dirt to enter and accumulate in the gap between the slider arrangement and the main body of the device and may fall into the HNB device.

[0003] To address the problem of the bulging cover, several spherical covers have been proposed in the prior art. However, these covers mainly focus on the problem of avoiding the bulging structure of the sliding cover and do not address the problem of dirt that accumulates on the cover and falls into the opening and the chamber where the aerosol is formed.

[0004] For example, a spherical cover that can be rotated from an open position to a closed position and vice versa is known from Chinese Patent Application Publication No. 110916237A. This device does not address the problem of preventing dirt from falling into the cavity, much less provide a structure to prevent dirt from falling into the aerosol generating chamber. In fact, the cover is formed in such a way that dirt can easily aggregate on the cover and fall into the interior of the device.

[0005] Similarly, Chinese Utility Model Registration No. 210809286U describes another spherical cover that can be moved from an open position to a closed position by a rotational movement of the cover. The device in that application also does not address the problem of dirt falling into the cavity, and is also arranged so that dirt can easily accumulate at the edges of the cover and fall into the device. [Overview of the project] [Problems that the invention aims to solve]

[0006] Therefore, it is desirable to provide a cover for opening and closing the device that prevents the aggregation of dirt and unwanted objects from falling unintentionally into the device, particularly into the aerosol generation chamber. [Means for solving the problem]

[0007] The present invention provides a device having a cover that solves some or all of the above problems.

[0008] A first embodiment of the present invention is an aerosol generating device comprising a housing, an aerosol generating chamber configured to receive an aerosol generating article through an opening in the chamber, a cover comprising a channel and at least one side wall forming the channel, configured to be in a closed position covering the opening or an open position exposing the opening, and a cavity for receiving the cover, positioned between the housing and the aerosol generating chamber, and the surface of the cavity defining a cylinder or sphere that determines the rotation of the cover, and the surface of the cavity comprising one or more sealing surfaces configured to form a sealing connection with respect to the cover, the one or more sealing surfaces preferably comprising a rubber material, wherein in the closed position, at least one side wall is positioned over the opening in the chamber so that an article cannot be received into the chamber through the channel, and in the open position, the channel is positioned over the opening in the chamber so that an article can be received into the chamber through the channel, and the cover is directed toward the aerosol generating device, configured to be rotated from the open position to the closed position and vice versa.

[0009] The above arrangement provides a rotatable cover that forms a sealing connection with the surface of the cavity on which the rotatable cover is located. These sealing connections prevent contamination that could be harmful to the device and / or cause an undesirable smoking experience from entering the inside of the device, such as a cavity or chamber.

[0010] According to the second embodiment, in the embodiment described above, the outer surface of the cover defines a cylinder or sphere corresponding to a cylinder or sphere defined by the cavity.

[0011] By rotating the cylinder or sphere within the cylindrical or spherical cavity, it is ensured that the cover remains in contact with the sealing surface while the cover rotates within the cavity. For example, when a spherical cover is rotated within a spherical cavity, the cover and cavity always form a sealing connection at the same position, regardless of the cover's orientation.

[0012] According to a third embodiment, in any one of the embodiments described above, the cover is preferably configured to rotate about an axis of rotation of a cavity that extends substantially perpendicular to the longitudinal direction in which the chamber extends.

[0013] The above configuration ensures that when the cover is rotated around the cavity's axis of rotation, rotating the cover moves it from the closed position to the open position and vice versa.

[0014] According to the fourth embodiment, in any of the embodiments described above, the cover contacts the surface of the cavity only at the sealing surface.

[0015] The above configuration reduces rotational resistance caused by the sealing surface contacting the cover. Therefore, it becomes easier to rotate the cover from the closed position to the open position and vice versa.

[0016] According to the fifth embodiment, in any of the embodiments described above, in the closed position, at least one side wall is configured to form a substantially flush continuity with the outer surface of the housing.

[0017] In this way, when the cover is rotated, it prevents dirt that could fall into the cavity and chamber from accumulating on the edges of the cover.

[0018] According to the sixth embodiment, in the embodiments described above, at least one side wall includes a substantially flat side wall portion configured to form a substantially flush continuity with the outer surface of the housing.

[0019] The above arrangement allows the cover to form a continuous portion that is substantially flush with the outer surface of the housing. For example, if at least one side wall is spherical, rotating the cover may cause dirt to accumulate at the edge of the cover and fall into the cavity. A substantially flat side wall portion prevents this.

[0020] According to the seventh embodiment, in any of the embodiments described above, in the closed position, at least one side wall is configured to engage with a side wall connecting the chamber to the cavity.

[0021] When the cover engages with the side wall connecting the chamber to the cavity, it prevents debris that could enter the cavity and potentially lead to an unpleasant smoking experience from falling into the chamber.

[0022] According to the eighth embodiment, in the embodiments described above, at least one side wall includes a substantially spherical, dome-shaped side wall portion configured to engage with a side wall connecting the chamber to the cavity.

[0023] The spherical, dome-shaped sidewall portion is particularly well suited to maintaining contact with the spherical / cylindrical cavity when the cover is rotated. For example, at least one sidewall portion oriented toward the chamber may have this substantially spherical, dome-shaped sidewall portion, which improves the connection as described in the prior embodiments.

[0024] According to the ninth embodiment, in any of the embodiments described above, the sealing surface is positioned in the region of the cavity adjacent to the chamber such that the cover and the side wall of the chamber are sealed to each other.

[0025] By positioning the sealing surface adjacent to the housing opening, a sealing contact is formed at the housing opening to prevent dirt from entering the cavity. In particular, cylindrical / spherical covers and cavities form sealing connections at the housing opening in both the open and closed positions. Similarly, chambers and covers form sealing connections at the chamber opening in both the open and closed positions.

[0026] According to the tenth embodiment, in any one of the foregoing embodiments, the housing has an opening that is connected to the cavity and, in the open position, an aerosol-generating article is received by the chamber through the opening of the housing, and in the closed position, at least one side wall is configured to be positioned over the opening of the housing so that the article cannot be received through the opening of the housing.

[0027] As described above, in the open position, at least one side wall is rotated to a position where an aerosol-generating article is received into the chamber where aerosol is formed through the opening in the housing and through the channel of the cover. In the closed position, the cover is rotated such that at least one side wall is moved to a position where at least one side wall closes / shields the opening of the housing.

[0028] According to the eleventh embodiment, in any one of the foregoing embodiments, the sealing surface is disposed in a region of the cavity adjacent to the opening of the housing such that the cover and the housing adjacent to the opening are sealed against each other.

[0029] According to the twelfth embodiment, in any one of the foregoing embodiments, the channel has a tapered shape and the perimeter of the channel decreases towards the chamber when the cover is in the open position.

[0030] The tapered shape of the channel facilitates the insertion of the aerosol-generating article into the device and the chamber. In particular, the tapered shape reduces the jamming of the aerosol-generating article and the cover during the insertion of the article into the channel when the cover has not fully reached the open position.

[0031] According to the 13th embodiment, in any one of the embodiments described above, at least one side wall preferably includes recesses and / or protrusions configured to be accessible by a user in a closed position, and the cover is further configured to be moved from an open position to a closed position and / or vice versa by, for example, applying a pushing or pulling force to the recesses and / or protrusions with a fingernail.

[0032] According to the 14th embodiment, in any one of the embodiments described above, the cover is configured to move between an open position and a closed position by force applied to the cover by the user's fingers relative to the rotating handle, by a pushing or pulling motion directly applied by the user's fingers, or by a motor.

[0033] In the following, preferred embodiments will be described with reference to the attached drawings for illustrative purposes only. [Brief explanation of the drawing]

[Figure 2a] This is a side view of an aerosol generating device with the cover in the closed position. [Figure 2b] This is a side view of an aerosol generating device with the cover in an intermediate position.

[Figure 4a] This is an external view of an aerosol generating device showing a rotary handle in an exemplary embodiment. [Figure 4b] This is an external view of an aerosol generating device showing a rotary handle in another exemplary embodiment. [Figure 5a] This is a side view of the aerosol generating device. [Figure 5b] This is a side view of an aerosol generating device having an opening mechanism in a further exemplary embodiment. [Figure 6] This is a perspective side view of an aerosol generating device having a motor in yet another exemplary embodiment. [Modes for carrying out the invention]

[0035] Preferred embodiments of the present invention will be described below with reference to the drawings.

[0036] Figure 1 is a side view of an aerosol generating device 100 according to an exemplary embodiment. The aerosol generating device 100 includes a housing 110, an aerosol generating chamber 120 for receiving an aerosol generating article 200, and a cavity 140 positioned between the aerosol generating chamber 120 and an opening 111 of the housing 110. The aerosol generating device 100 further includes a cover 130 positioned inside the cavity 140.

[0037] In the embodiment shown in Figure 1, the aerosol generating chamber 120 has a cylindrical shape configured to receive an aerosol generating article 200 having a substantially cigarette-like shape. However, the aerosol generating chamber 120 is not limited to a cylindrical shape, as it can also have an angular shape. In some embodiments, the aerosol generating chamber 120 includes a heating element (not shown), which is located inside the aerosol generating chamber 120, adjacent to and / or close to the aerosol generating chamber 120. Preferably, the aerosol generating chamber 120 includes an opening 121 at one end of a cylindrical aerosol generating chamber 120, the opening 121 being located adjacent to or at least at the closest end of the aerosol generating chamber 120 to the cavity 140.

[0038] The cover 130 is located inside the cavity 140 and includes a channel 134 formed by at least one sidewall, the channel 134 preferably having a tapered shape. The cover 130 is configured to rotate from a closed position covering the opening 121 of the aerosol generation chamber 120 to an open position exposing the opening 121 and vice versa. Preferably, the cover 130 has a substantially cylindrical or substantially spherical shape. In the embodiment shown in Figure 1, the cover 130 has a substantially cylindrical shape, and at least one sidewall includes a substantially flat sidewall portion 132 and a substantially spherical dome-shaped sidewall portion 133 opposite the substantially flat sidewall portion 132. In this embodiment, the substantially flat sidewall portion 132 and the substantially spherical dome-shaped sidewall portion 133 form the channel 134. However, at least one sidewall may also be molded in any other suitable way so that at least one sidewall can rotate from a closed position to an open position and vice versa. For example, at least one sidewall may also include a plurality of substantially flat sidewall portions 132 or a plurality of substantially semi-domed sidewall portions 133. The cover 130 may also have a substantially conical shape or a substantially rectangular parallelepiped shape. In other examples, the cover 130 may preferably include one sidewall which includes a substantially flat sidewall portion 132. In these embodiments, the channel 134 is not surrounded by at least one sidewall but is adjacent to at least one sidewall.

[0039] At least one side wall is configured such that, in the closed position, the article 200 cannot be received into the chamber through the channel 134, with at least one side wall positioned over the opening 121 of the chamber. For example, at least one side wall may be configured in the closed position to engage / contact with the side wall of the aerosol generating chamber 120, preferably at the position where the aerosol generating chamber 120 connects to the cavity 140. Preferably, in the closed position, at least one side wall is configured such that a substantially flat side wall portion 132 engages / contacts with the housing 110, and a substantially spherical dome-shaped side wall portion 133 engages / contacts with the side wall of the aerosol generating chamber 120.

[0040] The cavity 140 includes a surface 141 that defines a cylinder or sphere that determines the rotation of the cover 130. In fact, the cover 130 is preferably configured to rotate about an axis of rotation of the cavity 140 that extends substantially perpendicular to the longitudinal direction of the chamber 120 (indicated by the center of the cavity 140 in Figure 1, indicated by "x").

[0041] For example, if the outer surface of the cover 130 defines a substantially rectangular parallelepiped shape, the rectangular parallelepiped cover 130 is positioned inside the cavity 140 such that when the cover 130 is rotated from the open position to the closed position, the rotating rectangular parallelepiped cover traces a cylindrical volume.

[0042] The cavity 140 further includes one or more sealing surfaces 142, 143 configured to form a sealing connection with the cover 130, the one or more sealing surfaces 142, 143 preferably include a rubber material. The one or more sealing surfaces 142, 143 may be arranged such that they protrude from the surface 141 of the cavity 140 so that the cover 130 engages with the surface 141 of the cavity 140 only at the one or more sealing surfaces 142, 143. In the embodiment shown in Figure 1, the one or more sealing surfaces 142, 143 may include a first sealing surface 142 and a second sealing surface 143, the first sealing surface 142 located in a region of the cavity 140 relatively close to the opening 111 of the housing, and the second sealing surface 143 located in a region of the cavity relatively close to the opening 121 of the aerosol generation chamber. For example, in the closed position, at least one side wall of the cover 130 may engage with the opening 111 of the housing and the opening 121 of the aerosol generating chamber by one or more sealing surfaces 142, 143. However, the one or more sealing surfaces 142, 143 may also be positioned so that, during rotation of the cover 130, the cover 130 contacts the one or more sealing surfaces 142, 143 and the portion of the side of the cavity 140 that is not part of the one or more sealing surfaces 142, 143.

[0043] A user intending to consume the aerosol obtained by heating the aerosol-generating article 200 inserts the article 200 into the chamber 120 through the opening 111 of the housing 100, through the channel 134, and through the opening 121, where it is heated to generate an aerosol. The aerosol-generating article 200 is preferably a tobacco article substantially in the shape of a cigarette, and preferably a non-combustible heated tobacco article. However, the tobacco material may also be heated to combust. In other embodiments, the tobacco article is a capsule containing a compartment for receiving an aerosol-generating liquid configured to generate an aerosol when heated. In such embodiments, the heating element may be located either within the aerosol-generating device 100 or within the capsule containing the compartment.

[0044] Figures 2a, 2b, and 2c show a side view of an aerosol generating device 100 according to an exemplary embodiment. In each of Figures 2a, 2b, and 2c, the cover 130 of the device 100 is positioned in a different location. Specifically, Figure 2a shows the cover 130 in a closed position, Figure 2b shows the cover 130 in an intermediate position, and Figure 2c shows the cover in an open position. The aerosol generating device 100 in this embodiment includes a housing 110 having an opening 111, an aerosol generating chamber 120 having an opening 121, a cavity 140 between the housing 110 and the chamber 120, and a cover 130 positioned within the cavity 140, the cover including a substantially flat sidewall portion 132 and a substantially spherical dome-shaped sidewall portion 133. In this embodiment, the cavity 140 includes a first sealing surface 142 relatively close to the opening 111 of the housing and a second sealing surface 143 relatively close to the opening 121 of the aerosol generation chamber, and the cover 130 is in contact with the cavity surface 141 only by the sealing surfaces 142 and 143.

[0045] As illustrated with reference to Figure 1, in the closed position (Figure 2a), at least one sidewall of the cover is positioned so that the aerosol generating article 200 cannot be received into the aerosol generating chamber 120 through the channel 134. A substantially flat sidewall portion 132 engages with the housing 110 by a first sealing surface 142, and a substantially spherical dome-shaped sidewall portion 133 engages with the aerosol generating chamber 120 by a second sealing surface 143. In this way, sealing contacts are formed between the cover 130 and the housing 110 and between the cover 130 and the chamber 120. The sealing contacts prevent particles from unintentionally entering the aerosol generating device 100, particularly the aerosol generating chamber 120. For example, the sealing contacts prevent dirt from falling into the cavity 140, particularly into the aerosol generating chamber 120, when the device is not in use. Furthermore, the sealing contact also prevents particles such as tobacco residue or other aerosol-generating substances from unintentionally leaking from the aerosol generating device 100, particularly the aerosol generating chamber 120.

[0046] As shown in Figure 2a, by positioning the cover 130, the substantially flat sidewall portion 132 of the cover 130 forms a substantially flush continuity with the housing 110. This prevents dirt from accumulating on the edge of the cover 130 adjacent to the housing 110. This prevents dirt from falling into the cavity 140 when the cover 130 is moved from the closed position to the open position. By providing a substantially spherical dome-shaped sidewall portion 133 opposite the substantially flat sidewall portion 132, the stability of the cover 130 within the cavity 140 is improved, and sealing contact between the cover 130 and the sidewall of the chamber 120 is enabled.

[0047] Figure 2b shows the cover rotating from the closed position to the open position. Any position of the cover between the open and closed positions is referred to in this application as the intermediate position. As can be seen in Figure 2b, it is preferable to position one or more sealing surfaces 142, 143 such that the cover 130 remains in contact with one or more sealing surfaces 142, 143 even in the intermediate position. For example, by extending the protruding portions of the sealing surfaces 142, 143 from the edges of the cavity (from the respective regions near the openings 111 and 121) toward a portion of the cavity surface 141 that is further away from the edges of the cavity 140, it is ensured that the cover 130 remains in contact with one or more sealing surfaces 142, 143 during the full rotation from the closed position to the open position. This ensures smooth rotation and prevents the cover 130 from jamming. The side of the cover 130 closest to the chamber 120 includes a substantially spherical, dome-shaped sidewall portion 133, which increases the contact area with the cavity 140 during rotation of the cover 130, thereby improving the sealing connection.

[0048] If the channel 134 has a tapered shape, insertion of the aerosol-generating article 200 becomes easier even if the cover 130 has not reached the fully open position. The tapered shape of the channel 134 facilitates insertion of the aerosol-generating article 200 into the channel 134. In particular, the tapered shape reduces the likelihood of the aerosol-generating article 200 and the cover 130 becoming clogged during insertion of the aerosol-generating article 200 into the channel 134 when the cover 130 has not reached the fully open position.

[0049] Figure 2c shows the cover 130 in the open position. In this position, the channel 134 is positioned over the opening of the chamber 120 so that the article 200 can be received by the chamber 121 through the channel 134. Preferably, in the open position, at least one side wall of the cover 130 is positioned such that a portion of at least one side wall protrudes from the opening of the housing in the direction opposite to the insertion direction of the aerosol-generating article 200. This prevents dirt from falling into the channel 134 and thereby into the chamber 120 when the cover 130 is in the open position. Furthermore, in the open position, the substantially flat side wall portion 132 and the substantially spherical dome-shaped side wall portion 133 form a sealing contact with the chamber 120 and the housing 110 by the first sealing surface 142 and the second sealing surface 143. This prevents particles such as dirt from entering the cavity 140 when the cover 130 is in the open position.

[0050] Referring to Figure 3, the sealing contact by the sealing surfaces 142 and 143 will be described in more detail. For a better understanding of the sealing contact, the housing 110 is not shown. According to the embodiment shown in Figure 3, the side wall of the chamber 120 applies upward pressure (towards the cavity 140) to the second sealing surface 143. This pressure continues through the sealing surface toward the cover 130 so that a sealing contact is formed. Since the chamber 120 in Figure 3 has a substantially cylindrical shape, the side wall of the chamber 120 applies circular pressure toward the cavity 140. This ensures that in the open position, a sealing contact is formed between the substantially flat side wall portion 132 and the side wall of the chamber 120, and between the substantially spherical dome-shaped side wall portion 133 and the side wall of the chamber 120. In this example, the cover 130 is fabricated from a rigid material so that the upward pressure from the chamber 120 is further transmitted to the first sealing surface 142 so that a sealing contact is similarly formed toward the cover 130 and the housing 110.

[0051] To improve the sealing contact between the cover 130 and the chamber 120, it is preferable to embed the side wall of the chamber 120 inside the sealing surface of the cavity 140, as shown in Figure 3.

[0052] To improve the sealing contact between the cover 130 and the housing 110, it is preferable to provide a first sealing surface 142 with a first portion and a second portion projecting from the first portion in the direction opposite to the insertion direction of the aerosol generating article 200. When the first and second portions are provided, the surface of the housing 100 adjacent to / forming the opening 111 abuts with the second portion, and the surface of the housing 110 facing inward towards the aerosol generating device 100 abuts with the first portion. This increases the contact area between the cover 130 and the housing 110, thereby improving the sealing contact between the cover 130 and the housing 110.

[0053] Figures 4a and 4b show exemplary opening mechanisms for rotating the cover 130 of the aerosol generating device 100 from a closed position to an open position. In the embodiments shown in Figures 4a and 4b, the rotary handle 151 is positioned at different locations on the outer surface of the housing 110 (the surface of the housing facing away from the inner region of the housing). The rotary handle 151 is electrically or mechanically connected to the cover 130 such that rotating the rotary handle 151 causes the cover to rotate from a closed position to an open position and vice versa.

[0054] When the rotary handle 151 is positioned as shown in Figure 4a, rotating the rotary handle 151 in direction R causes the cover 130 to rotate in direction R'. Conversely, rotating the rotary handle 151 in the opposite direction to direction R causes the cover 130 to rotate in the opposite direction to direction R'. In this example, the cavity 140 and cover 130 are positioned such that rotating the cover 130 in the direction opposite to direction R' causes the cover 130 to move from a closed position to an open position and vice versa. This is achieved by positioning the cover 130 and cavity 140 such that rotating the cover in the direction opposite to direction R' results in a pitch motion (tilting forward or backward) of the cover 130 along the longitudinal direction of the channel 134.

[0055] When the rotary handle 151 is positioned as shown in Figure 4b, rotating the rotary handle 151 in direction Q causes the cover 130 to rotate in direction Q'. Conversely, rotating the rotary handle 151 in the opposite direction to direction Q causes the cover 130 to rotate in the opposite direction to direction Q'. In this example, the cavity 140 and cover 130 are positioned such that rotating the cover 130 in the direction opposite to direction Q' causes the cover 130 to move from a closed position to an open position and vice versa. This is achieved by positioning the cover 130 and cavity 140 such that rotating the cover in the direction opposite to direction Q' results in a pitch motion of the cover 130 along the longitudinal direction of the channel 134.

[0056] Figures 5a and 5b show another exemplary opening mechanism. In the embodiment of Figure 5a, the user can apply a pushing or pulling force to the outer surface of the cover 130 (the surface of the cover located opposite the direction in which the aerosol-generating article 200 is inserted). In the example shown in Figure 5a, the outer surface of the cover 130 is the outer surface of a substantially flat sidewall portion 132 of at least one sidewall of the cover 130.

[0057] In the embodiment shown in Figure 5b, at least one side wall portion 132 includes a recess 153 and a protrusion 152 configured to receive a pushing or pulling force from a user, for example, a fingernail. That is, a user can insert their fingernail into the recess and apply pressure to the protrusion 152 to rotate the cover 130 from the closed position to the open position and vice versa. By arranging the recess 153 and protrusion 152 as shown in Figure 5b, when the cover 130 is moved from the closed position to the open position, the rotation of the cover 130 causes the recess to move outward, so that dirt accumulated in the recess cannot enter the cavity 140. Furthermore, in the open position, the recess 153 and protrusion 152 are positioned such that the dirt accumulated in the recess is located above the protrusion 152 (in the opposite direction to the insertion direction of the aerosol generating article 200). This prevents dirt from falling into the cavity 140 when the cover 130 is in the open position.

[0058] Figure 6 shows the aerosol generating device viewed from an oblique side in the closed position. In this exemplary embodiment, the cavity 140 is formed inside a rectangular prism-shaped housing and includes a first sealing surface 142 near the opening 111 of the housing and a second sealing surface 143 near the chamber 120. In this embodiment, a substantially flat side wall portion 132 forms a flush continuity with the housing 110. The aerosol generating device 100 according to the embodiment shown in Figure 6 includes a motor 154. The motor 154 is located near the cover 130 and the cavity 140 and is configured to rotate the cover 130 from the closed position to the open position and vice versa. The user can activate the motor 154 remotely by pressing a button located on the aerosol generating device 100 or by wireless transmission such as Bluetooth®.
