Description

Technical Field

[0001] This application relates to the field of heat-not-burning technology, and in particular to a structure for preventing microphone failure and a heat-not-burning appliance. Background Technology

[0002] Heated non-combustible appliances generally include a housing and a heating element, a microphone element, and a power supply element disposed in the housing. The power supply element is used to supply power to the heating element and the microphone element, and the microphone element is used to detect the inhalation action and trigger the operation of the heated non-combustible appliance.

[0003] In related technologies, the microphone assembly is located below the heating element. The microphone assembly includes a deformable microphone section and a microphone located below the deformable section. The microphone is used to detect the deformation of the deformable section to trigger the operation of the heated non-combustible device. During inhalation, some aerosol-generating matrix (such as e-liquid) drips onto the deformable microphone section under gravity, causing a change in the weight of the deformable section and thus malfunctioning the microphone's counting function. Utility Model Content

[0004] In view of this, embodiments of this application provide a structure to prevent microphone failure and a heat-not-burning appliance to solve the problem of microphone counting function failure caused by aerosol generation matrix dripping onto the deformed part of the microphone.

[0005] The first aspect of this application discloses a microphone failure prevention structure, which is disposed between a heating element and a microphone element, the microphone failure prevention structure comprising:

[0007] A protrusion is provided on the receiving body and located on the side of the receiving body facing the heating element. The side wall of the protrusion is provided with an air inlet and outlet, which are closer to the heating element than the receiving surface.

[0008] The beneficial effects of the microphone failure prevention structure provided in this application embodiment are as follows: After the microphone failure prevention structure is installed between the heating element and the microphone element, during suction, the aerosol generation matrix passing through the heating element will drip onto the receiving surface of the receiving body, preventing the aerosol generation matrix from dripping onto the deformed part of the microphone. At the same time, the airflow during the suction process can enter the air passage of the whole machine through the air inlet and outlet, thereby ensuring the microphone's counting function. Since the air inlet and outlet are located on the side wall of the protrusion, and the air inlet and outlet are closer to the heating element than the receiving surface (which can be understood as the air inlet and outlet being higher than the receiving surface during suction), the aerosol generation matrix will neither drip into the air inlet and outlet nor flow into the air inlet and outlet from the receiving surface. Therefore, the normal operation of the air inlet and outlet can be guaranteed.

[0009] In some embodiments, the protrusion is located in the middle of the receiving body.

[0012] In some embodiments, a plurality of first reinforcing ribs are provided, and the plurality of first reinforcing ribs are arranged at intervals along the circumference of the receiving body; in the circumference of the receiving body, the air inlet and outlet are provided between two adjacent first reinforcing ribs.

[0013] In some embodiments, the connection position between the protrusion and the receiving surface is provided with a first chamfer, and / or the connection position between the first reinforcing rib and the receiving surface is provided with a second chamfer.

[0015] In some embodiments, the anti-microphone failure structure further includes a plurality of second reinforcing ribs, which are disposed on the inner wall of the ring and connected to the receiving body, and are arranged at intervals along the circumference of the receiving body.

[0016] In some embodiments, the protrusion further has a cavity with an opening facing the microphone assembly, and the air inlet / outlet communicates with the cavity.

[0017] In some embodiments, the protrusion includes a first column segment and a second column segment connected to the first column segment, the air inlet and outlet are disposed on the first column segment, and the second column segment is used for positioning and insertion into the heating component.

[0018] In some embodiments, the edge of the receiving body is provided with a wiring groove for routing wires connected to the heating component.

[0019] In some embodiments, the air inlet and outlet are circular, elliptical, or polygonal in shape; or...

[0020] The air inlet and outlet are circular in shape, and the diameter of the air inlet and outlet is 0.9-1.5mm.

[0021] The second aspect of this application provides a heat-not-burning appliance, which includes a housing, a heating element, a microphone assembly, and a microphone failure prevention structure as described in the first aspect, wherein the microphone failure prevention structure, the heating element, and the microphone assembly are disposed within the housing, and the microphone failure prevention structure is located between the heating element and the microphone assembly.

[0048] In related technologies, the microphone assembly is located below the heating element. The microphone assembly includes a deformable microphone section and a microphone located below the deformable section. The microphone is used to detect the deformation of the deformable section to trigger the operation of the heated non-combustible appliance. During the suction process, some aerosol-generated matrix drips onto the deformable microphone section under the influence of gravity. This adhesion to the deformable section causes a change in its weight, thereby disabling the microphone's counting function (i.e., counting one suction per breath).

[0049] To address the problem of microphone counting failure caused by aerosol matrix dripping onto the deformable part of the microphone, a structure to prevent microphone failure and a heating non-combustible appliance are proposed.

[0050] The first aspect of this application provides a structure to prevent microphone failure. Please refer to... Figure 1 , Figure 3 and Figure 4 The anti-microphone failure structure 20 is disposed between the heating element 30 and the microphone assembly 40. The anti-microphone failure structure 20 includes a receiving body 21 and a protrusion 22. The receiving body 21 has a receiving surface 211 facing the heating element 30, which is used to receive the aerosol generation matrix dripped by the heating element 30. The protrusion 22 is disposed on the receiving body 21 and located on the side of the receiving body 21 facing the heating element 30. The side wall of the protrusion 22 has an air inlet / outlet 2221, which is closer to the heating element 30 than the receiving surface 211.

[0051] The structure of the receiving body 21 is not limited in this application. For example, the receiving body 21 can be a disc, a column, etc. When the receiving body 21 is a disc, the shape of the disc can be circular, elliptical, polygonal, or irregular.

[0052] When the receiving body 21 is a disc, the diameter of the receiving body 21 may be 10-13 mm, for example, 11.5 mm; and the thickness of the receiving body 21 may be 0.8-1.2 mm, for example, 1 mm.

[0053] It is understandable that the receiving surface 211 can be a plane, a curved surface, a wavy surface, etc.

[0054] The receiving surface 211 is used to receive the aerosol generating matrix dripped from the heating element 30. That is, the aerosol generating matrix drips onto the receiving surface 211. Since the aerosol generating matrix has a high viscosity, it hardly moves on the receiving surface 211. Therefore, the aerosol generating matrix dripping onto the receiving surface 211 will not flow into the air inlet / outlet 2221.

[0055] It is understandable that the convex part 22 can be a convex pillar, a convex block, etc. When the convex part 22 is a convex pillar, the convex pillar can be a circular convex pillar, an elliptical convex pillar, a polygonal convex pillar, etc.; when the convex part 22 is a convex block, the convex block can be a cube convex block, a cuboid convex block, etc.

[0056] The protrusion 22 is provided on the support body 21. It can be understood that the protrusion 22 can be integrally formed with the support body 21, or the protrusion 22 can be fixed on the support body 21 by means of bonding, welding, fastener connection, etc.

[0057] The protrusion 22 is located on the side of the receiving body 21 facing the heating component 30. It can be understood that the protrusion 22 and the receiving surface 211 are on the same side of the receiving body 21.

[0058] The side wall of the protrusion 22 is provided with an air inlet and outlet 2221, that is, the orientation of the air inlet and outlet 2221 is perpendicular or substantially perpendicular to the dripping direction of the aerosol generating matrix, so as to prevent the aerosol generating matrix from dripping into the air inlet and outlet 2221.

[0059] The shape of the air inlet / outlet 2221 is not limited in this embodiment. For example, the shape of the air inlet / outlet 2221 can be circular, elliptical, or polygonal. When the shape of the air inlet / outlet 2221 can be circular, the diameter of the air inlet / outlet 2221 is 0.9-1.5 mm. For example, the diameter of the air inlet / outlet 2221 is 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, or 1.5 mm.

[0060] The air inlet / outlet 2221 is closer to the heating element 30 than the receiving surface 211. This can be understood as the air inlet / outlet 2221 being higher than the receiving surface 211 during suction. Therefore, after the aerosol generation matrix drips onto the receiving surface 211, it will not flow into the air inlet / outlet 2221.

[0061] It is understood that the number of protrusions 22 can be one or more. When the number of protrusions 22 is one, one or more air inlets and outlets 2221 can be provided on the protrusion 22.

[0062] Among them, the anti-microphone failure structure 20 is made of a high-temperature resistant material with low thermal conductivity, such as Peek (Polyether-ether-ketone), zirconia ceramic, etc., to reduce the impact of the heating component 30 on the anti-microphone failure structure 20.

[0063] The beneficial effects of the anti-microphone failure structure 20 provided in this application embodiment are as follows: After the anti-microphone failure structure 20 is installed between the heating element 30 and the microphone assembly 40, during suction, the aerosol generation matrix passing through the heating element 30 will drip onto the receiving surface 211 of the receiving body 21, preventing the aerosol generation matrix from dripping onto the microphone deformation part 411. At the same time, the airflow during the suction process can enter the whole machine air passage through the air inlet / outlet 2221, thereby ensuring the counting function of the microphone 43. Since the air inlet / outlet 2221 is located on the side wall of the protrusion 22 and the air inlet / outlet 2221 is closer to the heating element 30 than the receiving surface 211, the aerosol generation matrix will neither drip into the air inlet / outlet 2221 nor flow into the air inlet / outlet 2221 from the receiving surface 211. Therefore, the normal operation of the air inlet / outlet 2221 can be guaranteed, and the microphone deformation part 411 can also be kept unaffected.

[0064] Optionally, the overall height of the anti-microphone failure structure 20 is 4-5mm.

[0065] Please refer to Figure 4 In some embodiments, the protrusion 22 is located in the middle of the receiving body 21.

[0066] This can be understood as the protrusion 22 being located at or near the center of the receiving body 21, such that the receiving surface 211 is arranged around the protrusion 22.

[0067] Based on the above scheme, since the receiving surface 211 is arranged corresponding to the through hole 321 on the heating component 30 for the aerosol generation matrix to drip, by arranging the receiving surface 211 around the protrusion 22, the through hole 321 is arranged more evenly on the heating component 30, thereby making the heating component 30 heat up more evenly, and ultimately ensuring that the cigarette 200 is heated evenly.

[0068] Please refer to Figure 4 In some embodiments, the microphone failure prevention structure 20 further includes a first reinforcing rib 23, which is disposed on the support body 21 and located on the side of the support body 21 facing the heating component 30, and the first reinforcing rib 23 is connected to the protrusion 22.

[0069] The first reinforcing rib 23 is provided on the receiving body 21. It can be understood that the first reinforcing rib 23 can be integrally formed with the receiving body 21, or the first reinforcing rib 23 can be fixed on the receiving body 21 by means of bonding, welding, fastener connection, etc.

[0070] The first reinforcing rib 23 is located on the side of the receiving body 21 facing the heating component 30. It can be understood that the first reinforcing rib 23, the receiving surface 211, and the protrusion 22 are on the same side of the receiving body 21.

[0071] Based on the above scheme, the first reinforcing rib 23 is provided on the receiving body 21 and connected to the protrusion 22, which can strengthen the protrusion 22, ensure the positional relationship between the protrusion 22 and the receiving body 21, and thus ensure the positional relationship between the air inlet / outlet 2221 and the receiving surface 211, ensuring that the aerosol generation matrix will not enter the air inlet / outlet 2221.

[0072] Please refer to Figure 4 In some embodiments, the first reinforcing rib 23 extends radially along the receiving body 21, the first end 231 of the first reinforcing rib 23 is connected to the protrusion 22, the second end 232 of the first reinforcing rib 23 is located at the edge of the receiving body 21, and the second end 232 of the first reinforcing rib 23 is provided with a guide slope 2321 for guiding the assembly of the receiving body 21.

[0073] The first end 231 of the first reinforcing rib 23 is connected to the protrusion 22, and the second end 232 of the first reinforcing rib 23 is located at the edge of the support body 21. That is, the first reinforcing rib 23 is relatively long in the radial direction of the support body 21. It can be understood that the first reinforcing rib 23 is elongated, so that the first reinforcing rib 23 can also strengthen the support body 21. It should be noted that when the first end 231 of the first reinforcing rib 23 is connected to the protrusion 22, it should avoid the air inlet / outlet 2221.

[0074] It is understandable that the guiding slope 2321 can be a straight slope or an arc-shaped slope.

[0075] Based on the above technical solution, the guidance of the guide slope 2321 is beneficial to the assembly of the anti-microphone failure structure 20.

[0076] In other embodiments, based on the first end 231 of the first reinforcing rib 23 being connected to the protrusion 22, the second end 232 of the first reinforcing rib 23 can be a distance away from the edge of the support body 21. That is, the first reinforcing rib 23 is relatively short in the radial direction of the support body 21. At this time, a chamfer can be provided at the edge of the support body 21 to facilitate the assembly of the microphone failure prevention structure 20.

[0077] Please refer to Figure 4 In some embodiments, multiple first reinforcing ribs 23 are provided, and the multiple first reinforcing ribs 23 are arranged at intervals along the circumference of the receiving body 21; in the circumference of the receiving body 21, air inlets and outlets 2221 are provided between two adjacent first reinforcing ribs 23.

[0078] There are multiple first reinforcing ribs 23. It can be understood that the number of first reinforcing ribs 23 can be two, three, four or more.

[0079] Optionally, multiple first reinforcing ribs 23 are evenly spaced along the circumference of the receiving body 21 to ensure the stability of the protrusion 22 under stress.

[0080] The air inlet and outlet 2221 is located between two adjacent first reinforcing ribs 23. It can be understood that when there are two first reinforcing ribs 23, one or two air inlets and outlets 2221 can be provided; when there are three first reinforcing ribs 23, one, two or three air inlets and outlets 2221 can be provided; when there are four first reinforcing ribs 23, one, two, three or four air inlets and outlets 2221 can be provided.

[0081] It should be noted that multiple first reinforcing ribs 23 divide the receiving surface 211 into multiple receiving areas. For example, when there are two first reinforcing ribs 23, there are two receiving areas; when there are three first reinforcing ribs 23, there are three receiving areas; and when there are four first reinforcing ribs 23, there are four receiving areas.

[0082] Based on the above technical solution, by setting multiple first reinforcing ribs 23, the structural strength of the protrusion 22 can be further improved.

[0083] In some embodiments, the connection position between the protrusion 22 and the receiving surface 211 is provided with a first chamfer 24, and the connection position between the first reinforcing rib 23 and the receiving surface 211 is provided with a second chamfer 25.

[0084] It is understandable that the first chamfer 24 and the second chamfer 25 can be either beveled or rounded.

[0085] Based on the above technical solution, after the aerosol matrix dripping onto the protrusion 22 and the first reinforcing rib 23 flows downward, it will flow towards the receiving surface 211 under the guidance of the chamfer, and will not accumulate on the side walls of the protrusion 22 and the first reinforcing rib 23.

[0086] In other embodiments, a first chamfer 24 may be provided at the connection position between the protrusion 22 and the receiving surface 211, and a second chamfer 25 may not be provided at the connection position between the first reinforcing rib 23 and the receiving surface 211; or, a second chamfer 25 may be provided at the connection position between the first reinforcing rib 23 and the receiving surface 211, and a first chamfer 24 may not be provided at the connection position between the protrusion 22 and the receiving surface 211.

[0087] Please refer to Figure 4 In some embodiments, the anti-microphone failure structure 20 further includes a ring 26, which is disposed on the support body 21 and located on the side of the support body 21 facing the microphone assembly 40. The ring 26 is used to be inserted into the microphone assembly 40.

[0088] Optionally, the ring 26 is a circular ring.

[0089] The ring 26 is disposed on the receiving body 21. It can be understood that the ring 26 can be integrally formed with the receiving body 21, or the ring 26 can be fixed on the receiving body 21 by means of bonding, welding, fastener connection, etc.

[0090] The ring 26 is located on the side of the receiver 21 facing the microphone assembly 40. It can be understood that the ring 26 and the protrusion 22 are located on opposite sides of the receiver 21.

[0091] Please refer to Figure 7 Optionally, the microphone assembly 40 includes a microphone silicone 41 with a socket 412, into which a ring 26 is inserted. The socket 412 contains a sealing ring rib 4121, and the outer wall of the ring 26 is sealed to the sealing ring rib 4121 to ensure sealing performance.

[0092] Based on the above technical solution, since the microphone silicone 41 has a certain elasticity, after the ring 26 is inserted into the socket 412, the outer wall surface of the ring 26 can be sealed and matched with the sealing ring rib 4121, which makes assembly relatively convenient while ensuring sealing performance.

[0093] In other embodiments, the ring 26 may be omitted, and the side of the receiving body 21 facing away from the protrusion 22 may be bonded to the edge of the insertion hole 412 with sealant to ensure sealing performance.

[0094] Please refer to Figure 5 In some embodiments, the microphone failure prevention structure 20 further includes a plurality of second reinforcing ribs 27, which are disposed on the inner wall of the ring 26 and connected to the support body 21, and are arranged at intervals along the circumference of the support body 21.

[0095] It is understandable that the number of second reinforcing ribs 27 can be two, three, four or more.

[0096] The second reinforcing rib 27 is disposed on the inner wall of the ring body 26 and connected to the support body 21. It can be understood that the second reinforcing rib 27 can be integrally formed with the ring body 26 and the support body 21, or the second reinforcing rib 27 can be fixedly connected to the ring body 26 and the support body 21 by means of bonding, welding, fastener connection, etc.

[0097] Optionally, multiple second reinforcing ribs 27 are evenly spaced along the circumference of the ring 26 to ensure the stability of the ring 26 under stress.

[0098] Based on the above technical solution, the multiple second reinforcing ribs 27 can strengthen the ring body 26 and ensure the stability of the sealing fit between the outer wall surface of the ring body 26 and the sealing ring rib 4121.

[0099] Please refer to Figures 3 to 5 In some embodiments, the protrusion 22 also has a cavity 2222 with an opening facing the microphone assembly 40, and the air inlet 2221 communicates with the cavity 2222.

[0100] It is understandable that the cavity 2222 can be connected to one, two, or three or more air inlets and outlets 2221.

[0101] During suction, the gas above the microphone deformation section 411 flows out through the concave cavity 2222 and the air inlet / outlet 2221 in sequence, creating a negative pressure above the microphone deformation section 411, which causes the microphone deformation section 411 to deform upward. The microphone 43 can detect the deformation of the microphone deformation section 411 to trigger the operation of the heated non-combustible appliance 100.

[0102] Based on the above technical solution, a cavity 2222 is opened on the protrusion 22, so that the cavity 2222 can be connected with multiple air inlets and outlets 2221, which is beneficial for air intake and exhaust during suction.

[0103] In other embodiments, the protrusion 22 may not have a recess 2222, but instead has a connecting hole processed on the protrusion 22. The first port of the connecting hole forms an air inlet / outlet 2221, and the second port of the connecting hole faces the microphone deformation part 411. For example, the shape of the connecting hole is L-shaped.

[0104] Please refer to Figure 3 , Figure 4 and Figure 6 In some embodiments, the protrusion 22 is a protruding post, which includes a first post segment 222 and a second post segment 221 connected to the first post segment 222. The air inlet and outlet 2221 is provided on the first post segment 222, and the second post segment 221 is used for positioning and insertion into the heating component 30.

[0105] Optionally, the convex pillar can be a cylinder.

[0106] The first column segment 222 is located between the support body 21 and the second column segment 221.

[0107] When the support body 21 is provided with a first reinforcing rib 23, the first end 231 of the first reinforcing rib 23 is connected to the first column segment 222.

[0108] The heating element 30 includes a heat exchange core 32, which has a positioning hole 322. The second column segment 221 is positioned and inserted into the positioning hole 322 to ensure the relative position of the anti-microphone failure structure 20 and the heating element 30.

The cigarette 200 is inserted into the heating tube 31 from the end of the heating tube 31 away from the microphone assembly 40. After the heating tube 31 heats up, the heat is conducted to the cigarette 200 through the heat exchange core 32, achieving low-temperature baking. The heat exchange core 32 has multiple through holes 321. During inhalation, under the action of gravity, the aerosol generation matrix drips through the through holes 321 onto the receiving surface 211 of the receiving body 21.

[0118] The heat exchange core 32 also has a positioning hole 322, which is located at or near the center of the heat exchange core 32.

The protrusion 22 and the ring 26 are located on opposite sides of the axial direction of the receiving body 21. The second column section 221 of the protrusion 22 is positioned and inserted into the positioning hole 322, and the ring 26 is inserted into the insertion hole 412, so that the anti-microphone failure structure 20 is located between the heating element 30 and the microphone element 40.

[0122] The receiving body 21, the protrusion 22, and the ring body 26 are integrally formed.

[0123] Optionally, the heating component 30 further includes a power supply component 50 located within the housing 10. The power supply component 50 supplies power to the heating component 30 and the microphone assembly 40. The anti-microphone failure structure 20, the heating component 30, and the microphone assembly 40 are located on the same side of the power supply component 50. Exemplarily, the power supply component 50 includes a battery cell.
