Description

Technical Field

[0001] The present invention relates to an aerosol-generating device comprising a cover which can be brought from an open position to a closed position and vice versa by rotating the cover. Background Art

[0002] Aerosol generating devices or electronic cigarettes are now mainstream products that simulate traditional tobacco cigarettes. There are many types of aerosol generating devices, one of which operates by heating tobacco products to generate aerosols without causing tobacco burning. These so-called heat-not-burn (HNB) devices are becoming more and more popular. Heat-not-burn devices are usually equipped with an opening for inserting aerosol-generating articles, which allows access to a heating system for heating aerosol-generating articles. These openings for allowing the insertion of aerosol-generating articles are usually sealed by a cover that is usually arranged in a sliding manner. These sliders are components that move over the opening for inserting aerosol-generating articles and are stacked on top of the device. These sliders are not only usually bulky, but also cause dirt to be trapped in the gap between the slider arrangement and the body of the device, accumulating and falling into the HNB device.

[0003] In order to solve the problem of bulky cover, some spherical shaped covers have been proposed in the prior art. However, these covers mainly focus on avoiding the bulky structure of the sliding cover and do not solve the problem of dirt accumulating at the cover and falling into the opening and into the aerosol forming chamber.

[0004] For example, from CN 110916237 A, it is known that by rotating the spherical shaped cover, the cover can be brought from an open position to a closed position and vice versa. The device does not solve the problem of preventing dirt from falling into the cavity, let alone 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 accumulate at the cover and fall into the interior of the device.

[0005] Similarly, CN 210809286 U describes another spherical shaped cover which can be brought from an open position to a closed position by rotating the cover. The device of this application also does not solve the problem of dirt falling into the cavity and is also arranged in such a way that dirt can easily collect at the edge of the cover and fall into the device.

[0006] It is therefore desirable to provide a cover for opening and closing the device such that dirt accumulation is avoided and dirt and unwanted objects are prevented from accidentally falling into the device, in particular into the aerosol generating chamber. Summary of the invention

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

[0008] A first embodiment of the present invention relates to an aerosol generating device, the aerosol generating device comprising: a housing; an aerosol generating chamber, the aerosol generating chamber being configured to receive an aerosol generating product through an opening of the chamber; a cover, the cover comprising a channel and at least one side wall forming the channel, the cover being configured to be in a closed position covering the opening, or in an open position exposing the opening; and a cavity, the cavity being used to receive the cover and being arranged between the housing and the aerosol generating chamber, and the surface of the cavity defining a cylindrical portion that determines the rotation of the cover The invention relates to a body or a sphere, the surface of the cavity includes one or more sealing surfaces configured to form a sealed connection against the cover, and the one or more sealing surfaces preferably include a rubber material, wherein, in the closed position, the at least one side wall is positioned on the opening of the chamber so that the product cannot be received into the chamber through the channel; in the open position, the channel is positioned on the opening of the chamber so that the product can be received into the chamber through the channel; and the cover is configured to be brought from the open position to the closed position by rotating the cover, and vice versa.

[0009] The above arrangement provides a rotatable cover that forms a sealed connection with the surface of the cavity in which it is located. These sealed connections prevent dirt from entering the interior of the device (such as the cavity or chamber), which may be harmful to the device or produce an undesirable smoking experience.

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

[0011] By rotating a cylinder or sphere in a cylindrical or spherical cavity, it is ensured that the cover remains in contact with the sealing surface during rotation of the cover in the cavity. For example, if a spherical cover rotates in a spherical cavity, the cover and cavity always form a sealed connection at the same position regardless of the orientation of the cover.

[0012] According to a third embodiment, in any of the preceding embodiments, the cover is configured to rotate about a rotation axis of the chamber, the rotation axis preferably extending in a direction substantially perpendicular to a longitudinal direction in which the chamber extends.

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

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

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

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

[0017] In this way, dirt is prevented from accumulating at the edge of the cover, which dirt could fall into the cavity and the chamber if the cover is rotated.

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

[0019] The above arrangement enables the cover to be connected substantially flush with the outer surface of the housing. For example, if the at least one side wall has a spherical shape, dirt may collect at the edge of the cover and fall into the cavity when the cover is rotated. The substantially flat side wall portion prevents this.

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

[0021] If the cover engages with the side wall connecting the chamber to the cavity, dirt is prevented from falling into the chamber, which could lead to an unpleasant smoking experience once dirt has managed to enter the cavity.

[0022] In accordance with an eighth embodiment, in the previous embodiment, the at least one sidewall includes a generally spherical dome-shaped sidewall portion, the generally spherical cylindrical-shaped sidewall portion being configured to engage with a sidewall connecting the chamber with the cavity.

[0023] The spherical dome shaped side wall portion is particularly well suited to maintaining contact with a spherical / cylindrical shaped cavity when the cover is rotated. For example, the portion of the at least one side wall directed toward the cavity can have the generally spherical dome shaped side wall portion, which improves the connection as described in the previous embodiment.

[0024] According to a ninth embodiment, in any of the preceding embodiments, the sealing surfaces are arranged in a region of the cavity adjacent to the chamber such that the cover and the side wall of the chamber seal against each other.

[0025] By arranging the sealing surface adjacent to the opening of the housing, a sealing contact is formed at the opening of the housing, so that dirt cannot enter the cavity. In particular, by the cylindrical / spherical cover and the cavity, a sealing connection at the opening of the housing is formed in the open position and the closed position. Similarly, in the open position and the closed position, the chamber and the cover form a sealing connection at the opening of the chamber.

[0026] According to a tenth embodiment, in any of the aforementioned embodiments, the shell includes an opening, which is connected to the cavity and is configured so that in the open position, the aerosol generating product is received by the chamber through the opening of the shell, and in the closed position, the at least one side wall is positioned on the opening of the shell so that the product cannot be received through the opening of the shell.

[0027] By the above, in the open position, the at least one side wall is rotated to a position such that the aerosol-generating article is received through the opening of the housing, through the passage of the cover, into the aerosol-forming chamber. In the closed position, the cover is rotated so that the at least one side wall is brought to a position where the at least one side wall closes / blocks the opening of the housing.

[0028] According to an eleventh embodiment, in any one of the preceding embodiments, the sealing surfaces are arranged in a region of the cavity adjacent to the opening of the housing, so that the cover and the housing seal against each other adjacent to the opening.

[0029] In accordance with a twelfth embodiment, in any of the preceding embodiments, the channel has a tapered shape, and when the cover is in the open position, the circumference of the channel decreases toward the chamber.

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

[0031] According to a thirteenth embodiment, in any of the preceding embodiments, the at least one side wall comprises a recessed portion and / or a protruding portion, which is configured to be touched by a user, preferably by a user in the closed position, wherein the cover is further configured to be brought from the open position to the closed position by applying a pushing or pulling force at the recessed portion and / or the protruding portion, for example with the aid of a fingernail, and vice versa.

[0032] According to a fourteenth embodiment, in any of the preceding embodiments, the cover is configured to transition between the open position and the closed position by means of action of a user's fingers on a rotating handle, a pushing or pulling action directly applied by a user's fingers, or a force applied to the cover by a motor.

[0033] Preferred embodiments will now be described, by way of example only, with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Preferred embodiments of the present invention are described below with reference to the accompanying drawings.

[0045] Figure 1 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 arranged between the aerosol generating chamber 120 and an opening 111 of the housing 110. The aerosol generating device 100 further includes a cover 130 arranged in the cavity 140.

[0046] exist Figure 1In the illustrated embodiment, the aerosol generating chamber 120 has a cylindrical shape and is configured to receive an aerosol generating article 200 having a generally cigarette-like shape. However, the aerosol generating chamber 120 is not limited to a cylindrical shape, as an angular shape is also possible. In some embodiments, the aerosol generating chamber 120 comprises a heating element (not shown), wherein the heating element is arranged within the aerosol generating chamber 120, adjacent to the aerosol generating chamber 120 and / or in close proximity to the aerosol generating chamber 120. The aerosol generating chamber 120 comprises an opening 121 at one end of the preferably cylindrical aerosol generating chamber 120, wherein the opening 121 is arranged at an end of the aerosol generating chamber 120 adjacent to or at least closest to the cavity 140.

[0047] The cover 130 is arranged in the cavity 140 and includes a channel 134 formed by at least one side wall, wherein the channel 134 preferably has a conical shape. The cover 130 is configured to rotate from a closed position (covering the opening 121 of the aerosol generating 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. Figure 1 In the illustrated embodiment, the cover 130 has a generally cylindrical shape, wherein at least one side wall includes a generally flat side wall portion 132 and a generally spherical dome-shaped side wall portion 133 opposite to the generally flat side wall portion 132. In this embodiment, the generally flat side wall portion 132 and the generally spherical dome-shaped side wall portion 133 form a channel 134. However, the shape of the at least one side wall can also be arranged in any other suitable manner so that the at least one side wall can be rotated from a closed position to an open position and vice versa. For example, the at least one side wall can also include a plurality of generally flat side wall portions 132 or a plurality of generally semi-dome-shaped side wall portions 133. The cover 130 can also have a generally conical shape or a generally cubic shape. In other examples, the cover 130 can include a side wall, which preferably includes a generally flat side wall portion 132. In these embodiments, the channel 134 is not enclosed by the at least one side wall, but is adjacent to the at least one side wall.

[0048] At least one side wall is configured such that in the closed position the at least one side wall is positioned over the opening 121 of the chamber such that the article 200 cannot be received into the chamber through the passage 134. For example, at least one side wall may be configured to engage / contact the side wall of the aerosol generating chamber 120 in the closed position, preferably in a position where the aerosol generating chamber 120 is connected to the cavity 140. Preferably, at least one side wall is configured such that in the closed position the generally flat side wall portion 132 engages / contacts the housing 110 and the generally spherical dome-shaped side wall portion 133 engages / contacts the side wall of the aerosol generating chamber 120.

[0049] The cavity 140 comprises a surface 141 defining a cylinder or a sphere defining the rotation of the cover 130. In fact, the cover 130 is configured to rotate about the axis of rotation of the cavity 140 (at Figure 1 The chamber 140 is rotated (indicated by an “x” located at the center of the cavity 140), with the rotation axis preferably extending in a direction substantially perpendicular to the longitudinal direction in which the chamber 120 extends.

[0050] For example, if the outer surface of the cover 130 defines a generally cuboid shape, the cuboid-shaped cover 130 is disposed within the cavity 140 such that when the cover 130 is rotated from the open position to the closed position, the rotated cuboid-shaped cover describes a cylindrical volume.

[0051] The cavity 140 further comprises one or more sealing surfaces 142, 143 configured to form a sealed connection against the cover 130, wherein the one or more sealing surfaces 142, 143 preferably comprise a rubber material. The one or more sealing surfaces 142, 143 may be arranged such that the one or more sealing surfaces 142, 143 protrude from the surface 141 of the cavity 140, such that the cover 130 engages with the surface 141 of the cavity 140 only at the one or more sealing surfaces 142, 143. Figure 1 In the illustrated embodiment, the one or more sealing surfaces 142, 143 may include a first sealing surface 142 and a second sealing surface 143, wherein the first sealing surface 142 is arranged in a region of the cavity 140 relatively close to the opening 111 of the housing, and the second sealing surface 143 is arranged in a region of the cavity relatively close to the opening 121 of the aerosol generating 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 means of the one or more sealing surfaces 142, 143. However, the one or more sealing surfaces 142, 143 may also be arranged such that during rotation of the cover 130, the cover 130 contacts the one or more sealing surfaces 142, 143 and a portion of the side surface of the cavity 140 that is not part of the one or more sealing surfaces 142, 143.

[0052] A user who wants to consume the aerosol obtained by heating the aerosol-generating article 200 inserts the article 200 through the opening 111 of the housing 100, through the passage 134, through the opening 121 into the chamber 120, where the article is heated to generate an aerosol. The aerosol-generating article 200 is preferably a tobacco product in the shape of a general cigarette, preferably a heat-not-burn tobacco product. However, the tobacco material can also be heated to burn it. In other embodiments, the tobacco product is a capsule comprising a compartment for receiving an aerosol-generating liquid configured to generate an aerosol when heated. In such embodiments, the heating element can be arranged in the aerosol-generating device 100 or in a capsule comprising a compartment.

[0053] Figure 2 a. Figure 2 b and Figure 2 c shows a side view of an aerosol generating device 100 according to an exemplary embodiment. Figure 2 a. Figure 2 b and Figure 2 In each of c, the cover 130 of the device 100 is arranged at a different position. That is, Figure 2 a shows the cover 130 in the closed position, Figure 2 b shows the cover 130 in an intermediate position, and Figure 2 c shows the cover in an open position. In this embodiment, the aerosol generating device 100 comprises 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 arranged in the cavity 140, wherein the cover comprises a substantially flat side wall portion 132 and a substantially spherical dome-shaped side wall portion 133. In this embodiment, the cavity 140 comprises 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 generating chamber, wherein the cover 130 contacts the surface 141 of the cavity only by means of the sealing surfaces 142, 143.

[0054] As reference Figure 1 As described, in the closed position ( Figure 2a), at least one side wall of the cover is arranged so that the aerosol generating article 200 cannot be received into the aerosol generating chamber 120 through the passage 134. The substantially flat side wall portion 132 is engaged with the housing 110 by means of a first sealing surface 142, and the substantially spherical dome-shaped side wall portion 133 is engaged with the aerosol generating chamber 120 by means of a second sealing surface 143. In this way, a sealing contact is formed between the cover 130 and the housing 110 and a sealing contact is formed between the cover 130 and the chamber 120. The sealing contact prevents particles from accidentally entering the aerosol generating device 100, in particular the aerosol generating chamber 120. For example, the sealing contact prevents dirt from falling into the cavity 140, in particular the aerosol generating chamber 120, when the device is not in use. In addition, the sealing contact also prevents particles such as tobacco residues or other aerosol generating substances from accidentally escaping from the aerosol generating device 100, in particular the aerosol generating chamber 120.

[0055] Through Figure 2 The cover 130 is arranged as shown in FIG. a, and the substantially flat side wall portion 132 of the cover 130 is substantially flush with the housing 110. This prevents dirt from accumulating at 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 arranging the substantially spherical dome-shaped side wall portion 133 opposite the substantially flat side wall portion 132, the stability of the cover 130 in the cavity 140 is improved and a sealing contact between the cover 130 and the side wall of the chamber 120 is enabled.

[0056] Figure 2 b shows the cover during rotation from the closed position to the open position. Any arrangement of the cover between the open position and the closed position is referred to as an intermediate position in this application. Figure 2 As can be seen in Fig. 1b, the one or more sealing surfaces 142, 143 are preferably arranged so that the cover 130 remains in contact with the one or more sealing surfaces 142, 143 even when the cover 130 is in the intermediate position. For example, by extending the protruding portions of the sealing surfaces 142, 143 from the edge of the cavity (from the corresponding areas near the openings 111 and 121) toward the portion of the surface 141 of the cavity that is farther from the edge of the cavity 140, it is ensured that the cover 130 remains in contact with the one or more sealing surfaces 142, 143 during the full rotation from the closed position to the open position. This ensures that the rotation is smooth and prevents the cover 130 from getting stuck. The side of the cover 130 closest to the chamber 120 includes a sidewall portion 133 in a generally spherical dome shape, which increases the contact area with the cavity 140 during the rotation of the cover 130, thereby improving the sealed connection.

[0057] If the channel 134 has a tapered shape, it is facilitated to insert the aerosol-generating article 200 even if the cover 130 has not fully reached the open position. The tapered shape of the channel 134 facilitates the insertion of the aerosol-generating article 200 into the channel 134. In particular, when the cover 130 has not fully reached the open position, the tapered shape reduces the possibility of the aerosol-generating article 200 and the cover 130 getting stuck during the insertion of the aerosol-generating article 200 into the channel 134.

[0058] Figure 2 c shows the cover 130 in an open position. In this position, the channel 134 is positioned over the opening 121 of the chamber so that the article 200 can be received by the chamber 120 through the channel 134. Preferably, at least one side wall of the cover 130 is arranged so that in the open position, a portion of the at least one side wall protrudes from the opening of the housing in a 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 means of 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.

[0059] refer to Figure 3 The sealing contact by means of the sealing surfaces 142, 143 is described in more detail. For a better understanding of the sealing contact, the housing 110 is not shown. Figure 3 In the illustrated embodiment, the sidewall of the chamber 120 applies pressure upward (toward the cavity 140) against the second sealing surface 143. This pressure continues through the sealing surface toward the cover 130 so that a sealing contact is formed. Figure 3 The chamber 120 has a generally cylindrical shape, and the side wall of the chamber 120 exerts a circular pressure in the direction of the cavity 140. This ensures that in the open position, a sealing contact is formed between the generally flat side wall portion 132 and the side wall of the chamber 120, and a sealing contact is formed between the generally spherical dome-shaped side wall portion 133 and the side wall of the chamber 120. In this example, the cover 130 is made of a rigid material so that the upward pressure from the chamber 120 is further translated to the first sealing surface 142, so that a sealing contact is formed between the cover 130 and the housing 110 in a similar manner.

[0060] In order to improve the sealing contact between the cover 130 and the chamber 120, it is preferred that the side wall of the chamber 120 is embedded in the sealing surface of the cavity 140, such as Figure 3 shown.

[0061] In order to improve the sealing contact between the cover 130 and the housing 110, it is preferred that the first sealing surface 142 has a first portion and a second portion protruding from the first portion in a direction opposite to the insertion direction of the aerosol-generating article 200. When the first portion and the second portion are provided, the surface of the housing 100 adjacent to / forming the opening 111 contacts the second portion, and the surface of the housing 110 directed toward the interior of the aerosol-generating device 100 contacts the first portion. This improves the sealing contact between the cover 130 and the housing 110 because the contact area between the cover 130 and the housing 110 increases.

[0062] Figure 4 a and Figure 4 b shows an exemplary opening mechanism for rotating the cover 130 of the aerosol generating device 100 from the closed position to the open position. Figure 4 a and Figure 4 In the embodiment shown in FIG. 1 b, the rotating handle 151 is arranged at different positions on the outer surface of the housing 110 (the surface of the housing pointing in the opposite direction to the inner area of ​​the housing). The rotating handle 151 is electrically or mechanically connected to the cover 130, so that rotating the rotating handle 151 rotates the cover from the closed position to the open position, and vice versa.

[0063] When the handle 151 is rotated as Figure 4 When arranged as shown in a, rotating the rotating handle 151 in the direction R causes the cover 130 to rotate in the direction R'. Correspondingly, rotating the rotating handle 151 in the direction opposite to the direction R causes the cover 130 to rotate in the direction opposite to the direction R'. In this example, the cavity 140 and the cover 130 are arranged so that rotating the cover 130 in the direction R' or in the direction opposite to the direction R' causes the cover 130 to move from the closed position to the open position, and vice versa. This is achieved by arranging the cover 130 and the cavity 140 so that rotating the cover in the direction R' or in the direction opposite to the direction R' causes the cover 130 to pitch (tilt forward or backward) in the longitudinal direction of the channel 134.

[0064] When the handle 151 is rotated as Figure 4 b, rotating the rotating handle 151 in the direction Q causes the cover 130 to rotate in the direction Q'. Correspondingly, rotating the rotating handle 151 in the direction opposite to the direction Q causes the cover 130 to rotate in the direction opposite to the direction Q'. In this example, the cavity 140 and the cover 130 are arranged so that rotating the cover 130 in the direction Q' or in the direction opposite to the direction Q' causes the cover 130 to move from the closed position to the open position, and vice versa. This is achieved by arranging the cover 130 and the cavity 140 so that rotating the cover in the direction Q' or in the direction opposite to the direction Q' causes the cover 130 to pitch in the longitudinal direction of the channel 134.

[0065] Figure 5 a and Figure 5 b shows another exemplary opening mechanism. Figure 5 In the embodiment of a, the user can apply a pushing force or a pulling force to the outer surface of the cover 130 (the surface of the cover arranged on the side opposite to the insertion direction of the aerosol generating article 200). Figure 5 In the example shown in a, the outer surface of the cover 130 is the outer surface of a substantially flat side wall portion 132 of at least one side wall of the cover 130 .

[0066] exist Figure 5 In the embodiment shown in FIG. 1 , at least one side wall portion 132 includes a recessed portion 153 and a protruding portion 152, which are configured to receive a push or pull force from a user, for example, by means of a fingernail. That is, the user can insert his fingernail into the recessed portion and apply pressure to the protruding portion 152 to rotate the cover 130 from the closed position to the open position, or vice versa. Figure 5 b, if the cover 130 is moved from the closed position to the open position, the dirt accumulated in the recessed portion cannot enter the cavity 140, because the rotation of the cover 130 causes the recessed portion to move outward, so that the dirt cannot fall into the cavity 140. In addition, in the open position, the recessed portion 153 and the protruding portion 152 are arranged so that the dirt accumulated in the recessed portion is positioned on the top of the protruding portion 152 (in the direction opposite to the insertion direction of the aerosol-generating article 200). This prevents the dirt from falling into the cavity 140 when the cover 130 is in the open position.

[0067] Figure 6 An angled side view of the aerosol generating device in a closed position is shown. In this exemplary embodiment, the cavity 140 is formed within a cubic shaped enclosure and includes a first sealing surface 142 proximate the opening 111 of the housing and a second sealing surface 143 proximate the chamber 120. In this embodiment, the substantially flat side wall portion 132 is flush with the housing 110. Figure 6 In the illustrated embodiment, the aerosol generating device 100 includes a motor 154. The motor 154 is arranged near the cover 130 and the cavity 140, and is configured to rotate the cover 130 from a closed position to an open position, and vice versa. The user can remotely activate the motor 154 by pressing a button arranged on the aerosol generating device 100 or by means of a wireless transmission such as Bluetooth®. For example, the user can activate the motor 154 using an electronic device including a wireless transmitter / transceiver, which transmits a start signal to a receiver / transceiver in communication with the motor 154, wherein the motor 154 rotates the cover 130 based on the start signal.
