Description

Technical Field

[0001] This application relates to the field of heat-not-burning technology, specifically to a baffle and a heat-not-burning device. Background Technology

[0002] In heated non-combustible devices, in order to improve heating efficiency and reduce the probability of aerosol products clogging and producing odors due to direct contact between the aerosol product and the heating element, hot airflow is usually used to heat the aerosol product.

[0003] In heated non-combustible devices that use hot airflow for heating, a heat exchange core is often installed in the air inlet channel. The heat exchange core has a heat exchange air passage. When the airflow flows through the heat exchange air passage, it contacts the side wall of the heat exchange air passage to achieve heat exchange and form a hot airflow. However, because the inlet section of the heat exchange core has a cavity structure, the airflow velocity and air pressure decrease when flowing through the cavity, resulting in uneven airflow at the inlet of the heat exchange core and poor heat exchange effect of the heated non-combustible device. Utility Model Content

[0004] This application provides a baffle and a heating non-combustion device to solve the technical problem of poor heat exchange effect of the heating non-combustion device.

[0005] According to one aspect of this application, one embodiment provides a baffle installed in the air inlet channel of a heated non-combustible device and located on the air inlet side of a heat exchanger in the heated non-combustible device, the baffle and the heat exchanger being arranged in a first direction;

[0006] The spoiler includes an outer cylinder and a guide vane. The outer cylinder extends in the first direction, and both ends of the guide vane in the second direction are connected to the inner wall of the outer cylinder. The guide vane and the outer cylinder together form an airflow channel that penetrates the spoiler in the first direction. The guide vane has a spoiling portion, and the cross-sectional shape of the spoiling portion in the direction perpendicular to the first direction is a curved structure or a broken line structure. The curved structure or the broken line structure protrudes upward in a third direction, and the first direction, the second direction, and the third direction are perpendicular to each other.

[0007] In one alternative embodiment, the spoiler extends in the first direction, and the spoiler has the same cross-sectional shape at all points perpendicular to the first direction.

[0008] In one alternative embodiment, the spoiler has a thickness dimension in the third direction, and the thickness dimension of the spoiler is equal everywhere.

[0009] In one optional embodiment, the guide vane has a connecting portion that connects the turbulence-disrupting portion to the inner wall of the outer cylinder in the second direction. The connecting portion has a straight cross-sectional shape perpendicular to the first direction, and the straight structure extends in the second direction.

[0010] In one alternative embodiment, the guide vane has two connecting portions arranged on both sides of the turbulence portion in the second direction, the turbulence portion being located at the middle position of the guide vane in the second direction.

[0011] In one alternative embodiment, there are multiple guide vanes, with adjacent guide vanes spaced apart in the third direction, and the distance between adjacent guide vanes is equal everywhere in the second direction.

[0012] According to one aspect of this application, one embodiment provides a heated non-combustible device, including a device body and a baffle as described in any of the above claims. The device body has an air inlet channel and a receiving cavity, the receiving cavity being used to contain an aerosol product. The device body includes a heat exchanger, the heat exchanger having a heat exchange air passage communicating with the receiving cavity, the heat exchange air passage being communicating with the air inlet channel through the airflow channel.

[0013] In one alternative embodiment, at least a portion of the heat exchange duct and at least a portion of the airflow channel are staggered in a plane perpendicular to the first direction, the heat exchanger has a clearance recess, and the airflow channel communicates with the heat exchange duct through the clearance recess.

[0014] In one alternative embodiment, the device body includes a housing and a first bracket mounted within the housing, at least a portion of the air intake passage is located within the first bracket, the first bracket has a slot facing the heat exchanger in the first direction, the baffle is located within the mounting slot, and the baffle is clamped and fixed between the heat exchanger and the first bracket in the first direction.

[0015] In an optional embodiment, the main body of the device further includes a second bracket and a heating cylinder installed within the housing, the accommodating cavity being located within the second bracket, and one end of the first bracket being sealed and inserted into the second bracket in the first direction; a portion of the heat exchanger is located within the heating cylinder, and the heat exchanger and the heating cylinder are clamped between the first bracket and the second bracket in the first direction.

[0016] According to the above embodiments of the baffle and the heating non-combustion device, since the baffle is located on the air inlet side of the heat exchanger in the heating non-combustion device in the first direction, and the two ends of the guide vane in the baffle are connected to the outer cylinder in the second direction, the guide vane and the outer cylinder form an airflow channel that penetrates the baffle in the first direction. The guide vane has a baffle portion, and the cross-sectional shape of the baffle portion in the vertical first direction is a curved structure or a broken line structure that protrudes in the third direction. Thus, the baffle portion has a curved surface structure or a broken surface structure arranged in the second direction. When the airflow passes through the baffle portion, the airflow can be made to flow in the third direction in the vertical first direction to avoid the baffle portion. In this way, turbulence can be formed at the baffle portion, which helps to increase the airflow velocity, uniformize the airflow, and improve the heat exchange effect of the airflow in the heat exchanger.

Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0024] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0025] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0026] This application provides a flow deflector 2, which is applied in the air inlet channel 101 of the heating non-combustion device to guide the airflow, make the airflow turbulent, increase the airflow velocity, uniformize the airflow, and improve the heat exchange effect of the airflow in the heat exchanger 11.

[0027] Please refer to Figures 2 to 4 In this embodiment of the application, the baffle 2 is located on the air inlet side of the heat exchanger 11, and the baffle 2 and the heat exchanger 11 are arranged in a first direction. The first direction can be understood as the overall flow direction of the air inlet, or it can also be understood as the up and down direction when the heating non-combustion device is in use.

[0028] The spoiler 2 includes an outer cylinder 21 and a guide vane 22. The outer cylinder 21 extends in a first direction, and its outer contour shape is adapted to the cross-sectional contour shape of the air intake channel 101 so that the outer wall of the outer cylinder 21 can fit against the channel wall of the air intake channel 101, thus enabling the spoiler 2 to be installed in the air intake channel 101. For example, the outer cylinder 21 can be a cylindrical or square structure. The guide vane 22 is located inside the outer cylinder 21, and both ends of the guide vane 22 in a second direction are connected to the inner wall of the outer cylinder 21. The outer cylinder 21 can be integrally formed with the guide vane 22, and the second direction is perpendicular to the first direction. In this way, the guide vane 22 can divide the internal space of the outer cylinder 21, so that the guide vane 22 and the outer cylinder 21 enclose an airflow channel 23. This airflow channel 23 penetrates the spoiler 2 in the first direction and connects the air intake channel 101 and the heat exchange air passage 111 in the heat exchanger 11.

[0029] The guide vane 22 has a turbulence section 221, which is used to guide the airflow within the airflow channel 23. The turbulence section 221 can extend in the first direction. The cross-sectional shape of the turbulence section 221 in the direction perpendicular to the first direction is a curved structure or a broken line structure. The curved structure and the broken line structure in this cross-sectional shape are arranged to bulge upward in the third direction. The first direction, the second direction and the third direction are perpendicular to each other. This allows the turbulence section 221 to have a curved surface structure or a broken surface structure arranged in the second direction. When the airflow flows to the curved surface structure or the broken surface structure of the turbulence section 221, it can avoid the turbulence section 221. The turbulence section 221 guides the airflow to flow upward in the direction perpendicular to the first direction. This can break the original laminar flow state in the air intake channel 101 and form turbulence. This helps to accelerate the airflow velocity, make the airflow mix evenly, and keep the airflow in a turbulent state after entering the heat exchanger 11, thereby improving the heat exchange effect of the airflow in the heat exchanger 11.

[0030] In some embodiments, please refer to Figure 2 and Figure 3 The turbulence section 221 can penetrate the entire turbulence diffuser 2 in the first direction. The turbulence section 221 has multiple cross sections perpendicular to the first direction, and the multiple cross sections have the same shape. Thus, the turbulence section 221 forms a ridge-like structure extending in the first direction. It can only interfere with the airflow direction at the inlet of the airflow channel 23 to make the airflow turbulent. This can reduce the obstruction effect of the turbulence section 221 on the airflow, reduce the suction resistance of the heating non-combustion device, and avoid excessive suction resistance of the heating non-combustion device due to the addition of the turbulence diffuser 2 in the air intake channel 101.

[0031] Of course, in other embodiments, where the turbulence section 221 has little effect on the suction resistance of the heating non-combustion device, the turbulence section 221 can also be provided with multiple cross sections perpendicular to the first direction. Two adjacent cross sections are arranged at intervals in the first direction, and the shapes of the two adjacent cross sections are different. In this way, multiple protrusions are formed on the turbulence section 221 at intervals in the first direction. All the protrusions protrude towards the third direction. In this way, the airflow at the inlet of the airflow channel 23 and inside the airflow channel 23 can be disturbed by the protrusions to make the airflow turbulent, which can make the airflow mix more evenly and further improve the heat exchange effect of the airflow in the heat exchanger 11.

[0032] In other embodiments, the size of the turbulence-disrupting part 221 in the first direction is smaller than the size of the guide vane 22 in the first direction, as long as the cross-sectional shape of the turbulence-disrupting part 221 in the vertical first direction can form a curved structure or a broken line structure.

[0033] In some embodiments, in order to facilitate the processing and manufacturing of the spoiler 221 and the entire spoiler 2, and to ensure the structural strength of the entire spoiler 221, the guide vane 22 is provided to have a thickness dimension in the third direction, the thickness dimension of the spoiler 221 in the third direction is equal everywhere, and the spoiler 221 has a first surface and a second surface arranged opposite to each other in the third direction, and the curvature or bending angle of the first surface and the second surface are the same. This can facilitate the processing of the spoiler 2 and reduce the cost of the entire guide vane 22 and the spoiler 2.

[0034] Of course, in other embodiments, it is also feasible to set the first surface of the turbulence part 221 to be a plane and the second surface to be a folded or curved surface, as long as the turbulence part 221 can guide the airflow to flow in a third direction to form turbulence.

[0035] In some embodiments, please refer to Figure 3 and Figure 4 The guide vane 22 has a connecting portion 222, which is connected between the turbulence portion 221 and the inner wall of the outer cylinder 21 in the second direction. The connecting portion 222 has a straight cross-sectional shape in the vertical first direction and the straight structure extends in the second direction, thus ensuring the connection strength between the guide vane 22 and the outer cylinder 21.

[0036] Furthermore, in some embodiments, the guide vane 22 may have two connecting portions 222, which are arranged on both sides of the turbulence portion 221 in the second direction. The turbulence portion 221 is connected to the cylinder wall of the outer cylinder 21 through the connecting portions 222. This avoids the formation of the turbulence portion 221 at the end of the guide vane 22 in the second direction, which helps to further ensure the connection strength between the guide vane 22 and the outer cylinder 21. The turbulence portion 221 is located in the middle of the guide vane 22 in the second direction, which facilitates the processing of the turbulence portion 221 in the guide vane 22. The guide vane 22 may also be arranged symmetrically about the turbulence portion 221 in the second direction.

[0037] In some embodiments, the connection part 222 can be omitted, and multiple turbulence parts 221 can be provided on the guide vane 22. The multiple turbulence parts 221 are arranged at intervals in the second direction, that is, multiple protrusions or ridge structures are formed on the guide vane 22 at intervals in the second direction. In this way, the airflow can be guided to form multiple turbulences in the air intake channel 101 through multiple turbulence parts 221, so as to make the airflow mix evenly and further improve the heat exchange effect of the airflow in the heat exchanger 11.

[0038] In some embodiments, please continue to refer to Figure 3 and Figure 4 The turbulence diffuser 2 has multiple guide vanes 22, each with the same thickness direction. Adjacent guide vanes 22 are arranged at intervals in the third direction, so that multiple airflow channels 23 are formed in the turbulence diffuser 2 between adjacent guide vanes 22 and between the guide vanes 22 and the outer cylinder 21. Under the action of the turbulence diffuser 221, the airflow flowing through each airflow channel 23 can form turbulence, which can make the airflow mix more evenly in the airflow channel 23 and further improve the heat exchange effect of the airflow in the heat exchanger 11.

[0039] The distance between two adjacent guide vanes 22 is equal, so the width of all airflow channels 23 in the third direction is equal. The width of the airflow channel 23 can be 0.2 mm to 0.35 mm, which helps to ensure the flow area of ​​the airflow channel 23. In order to make the width of the airflow channel 23 located at the end in the third direction equal to the width of the other airflow channels 23, a recess or a protrusion is provided on the inner wall of the outer cylinder 21. The shape of the recess or the protrusion is adapted to the shape of the turbulence portion 221 on the guide vane 22 adjacent to the outer cylinder 21 in the third direction.

[0040] This application also provides a heating non-combustible device; please refer to [reference needed]. Figure 1 and Figure 2The heated non-combustible device includes a device body 1 and a baffle 2 as described in any of the above embodiments. The device body 1 has an air inlet channel 101 and a receiving cavity 102. The air inlet channel 101 and the receiving cavity 102 are arranged in a first direction. The receiving cavity 102 is used to contain aerosol products. The air inlet channel 101 is connected to the receiving cavity 102 to supply air into the receiving cavity 102 through the air inlet channel 101.

[0041] The main body 1 of the device includes a heat exchanger 11, which has a heat exchange air passage 111 communicating with the accommodating cavity 102. The heat exchange air passage 111 extends in a first direction and is located between the air inlet passage 101 and the accommodating cavity 102 in the first direction, that is, between the baffle 2 and the accommodating cavity 102. The heat exchange air passage 111 can be connected to the air inlet passage 101 through the airflow passage 23 in the baffle 2. The airflow flowing through the airflow passage 23 in the air inlet passage 101 has turbulence, and the turbulence can increase the heat exchange efficiency of the airflow in the heat exchange air passage 111.

[0042] In some embodiments, the heat exchanger 11 has multiple heat exchange air passages 111, and the turbulent 2 has multiple airflow channels 23. In order to further improve the heat exchange effect of the airflow in the heat exchanger 11, at least some of the heat exchange air passages 111 and at least some of the airflow channels 23 are arranged in a staggered manner in a plane perpendicular to the first direction. For example, multiple heat exchange air passages 111 can be arranged directly opposite the guide plate 22 in the first direction. In this way, when the airflow flowing out of the airflow channel 23 enters the heat exchange air passage 111, it will flow upward in a third direction under the interference of the channel wall of the heat exchange air passage 111, so as to form turbulence at the inlet of the heat exchange air passage 111, which can further improve the heat exchange effect of the airflow in the heat exchange air passage 111.

[0043] In some embodiments, to ensure more uniform mixing of the airflow before it enters the heat exchanger 11, please refer to... Figure 2 The heat exchanger 11 is provided with a relief recess 112, which is positioned towards the turbulent 2 in the first direction. The orthographic projections of the multiple airflow channels 23 in the plane perpendicular to the first direction are all located inside the orthographic projections of the relief recess 112 in the plane perpendicular to the first direction. This ensures that the airflow in the airflow channels 23 can flow into the relief recess 112 and form turbulence again and mix thoroughly in the relief recess 112, thereby further improving the heat exchange effect of the airflow in the heat exchange channel 111.

[0044] Of course, in other embodiments, the setting of the avoidance recess 112 in the heat exchanger 11 can be omitted, and the heat exchanger 11 and the baffle 2 can be arranged at intervals. The airflow discharged from the airflow channel 23 can be fully mixed between the heat exchanger 11 and the baffle 2 to improve the heat exchange effect of the airflow in the heat exchanger 11.

[0045] In some embodiments, please refer to Figure 2 The main body of the device 1 includes a housing 12 and a first bracket 13 installed in the housing 12. At least a portion of the air intake channel 101 is located in the first bracket 13, such as the entire air intake channel 101 being located in the first bracket 13, or a portion of the air intake channel 101 may also be made up of other components in the housing 12, such as a connector 15 connected to the first bracket 13. The first bracket 13 has a mounting groove 131 with a slot facing the heat exchanger 11 in the first direction. The end opening of the air intake channel 101, which communicates with the airflow channel 23 in the baffle 2 in the first direction, is located on the bottom wall of the mounting groove 131. The baffle 2 is located inside the mounting groove 131. The outer wall of the outer cylinder 21 in the baffle 2 can be interference-fitted with the side wall of the mounting groove 131 to ensure the position of the baffle 2 in the air intake channel 101. Alternatively, the heat exchanger 11 is located at the slot of the mounting groove 131. The heat exchanger 11 and the first bracket 13 clamp and fix the baffle 2 in the mounting groove 131 in the first direction to achieve the installation and positioning of the baffle 2 in the main body 1 of the device.

[0046] In some embodiments, the heat exchanger 11 can be installed between the air intake passage 101 and the accommodating cavity 102 by means of an interference fit.

[0047] In some embodiments, the main body 1 of the device further includes a second bracket 14 and a heating cylinder 16 installed in the housing 12. The accommodating cavity 102 is located inside the second bracket 14. One end of the first bracket 13 is sealed and inserted into the second bracket 14 in the first direction to ensure that the air intake channel 101 can communicate with the accommodating cavity 102. Part of the heat exchanger 11 is located inside the heating cylinder 16 and can be interference-fitted with the heating cylinder 16; or the end of the heat exchanger 11 with the relief recess 112 has an outer flange 113, which abuts against the end of the heating cylinder 16 in the first direction. The heat exchanger 11 and the heating cylinder 16 as a whole can be clamped and fixed between the first bracket 13 and the second bracket 14 in the first direction. In this way, the heating cylinder 16 and the heat exchanger 11 are installed and fixed in the main body 1 of the device, while also ensuring that the heat exchanger 11 can abut against the baffle 2 in the first direction, and the heat exchanger 11 and the baffle 2 form a mixing chamber for airflow mixing at the relief recess 112.

[0048] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
