Description

Technical Field

[0001] This application relates to the field of heat-not-burning technology, and in particular to a microphone failure prevention structure, microphone failure prevention component, and 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 housed within the housing. The power supply element supplies power to the heating element and the microphone element, and the microphone element detects the inhalation action and triggers 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 section of the microphone under gravity. This adhesion to the deformable section causes a change in its weight, thereby disabling the microphone's puff counting function. Utility Model Content

Since the anti-microphone failure structure is suspended in the negative pressure channel by the suspension part, it is convenient to disassemble and assemble the anti-microphone failure structure in the negative pressure channel.

[0015] In some embodiments, the column is a cylinder, an elliptical cylinder, or a prism; or, the column is a cylinder, and the diameter of the column is less than or equal to the width of the helical portion.

[0018] In some embodiments, the edge of the spiral portion forms a gap with the wall of the negative pressure channel; or, the edge of the spiral portion abuts against the wall of the negative pressure channel.

[0019] In some embodiments, a support step is provided in the negative pressure channel, and the suspension part is attached to the support step so that the anti-microphone failure structure is suspended in the negative pressure channel.

[0020] The third 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 component as described in the second aspect, wherein the microphone failure prevention component, the heating element, and the microphone assembly are disposed within the housing, and the microphone failure prevention component is located between the heating element and the microphone assembly.

[0050] 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-generating matrix drips onto the deformable microphone section under gravity. The aerosol-generating matrix adhering to the deformable microphone section causes a change in the weight of the deformable section, thereby causing the microphone's count function (i.e., one suction counts as one puff) to fail.

[0051] To address the problem of microphone counting failure caused by aerosol matrix dripping onto the deformable part of the microphone, a microphone failure prevention structure, a microphone failure prevention component, and a heating non-combustible appliance are proposed.

[0052] The first aspect of this application provides a structure to prevent microphone failure. Please refer to... Figure 1 , Figure 2 , Figure 3 and Figure 7 The microphone failure prevention structure 22 is installed inside the negative pressure channel 211. The microphone failure prevention structure 22 includes a column 221, a spiral part 222, and a suspension part 223. The column 221 is arranged along the extending direction of the negative pressure channel 211; the spiral part 222 is provided on the outer peripheral surface of the column 221, and the spiral part 222 has at least one turn; the suspension part 223 is provided on the column 221 and is used to suspend it inside the negative pressure channel 211. The suspension part 223 has a clearance channel 224 for the aerosol generation matrix to drip onto the spiral part 222.

[0053] The structure of the column 221 is not limited in this application. For example, the column 221 can be a cylinder, an elliptical cylinder, a prism, etc. It is understood that the column 221 can be a solid column; or, the column 221 can also be a hollow column, but it must be ensured that at least one end of the column 221 is a closed structure to prevent the aerosol generation matrix from dripping from the inside of the column 221 onto the microphone deformation part 411.

[0054] The column 221 and the microphone deformation part 411 should maintain a certain distance to avoid the column 221 affecting the deformation of the microphone deformation part 411 during suction.

[0055] The column 221 is arranged along the extension direction of the negative pressure channel 211, which can be understood as the extension direction of the center line of the column 221 being consistent with the extension direction of the negative pressure channel 211. Optionally, the column 221 is located at the middle or near the middle of the negative pressure channel 211, so that the dimensions of the spiral part 222 are the same or substantially the same from top to bottom.

[0056] The spiral part 222 is provided on the outer peripheral surface of the column 221. It can be understood that the spiral part 222 can be integrally formed on the outer wall surface of the column 221, or the spiral part 222 can be fixed on the outer peripheral surface of the column 221 by means of bonding, snap-fitting, welding, interference fit, fastener connection, etc.

[0057] The spiral part 222 has at least one turn, which can be understood as the spiral part 222 having one turn, one and a half turns, two turns, or three or more turns. This ensures that the aerosol generation matrix will drip onto the spiral part 222 and not onto the microphone deformation part 411.

[0058] It is understandable that the lead of the helical section 222 should be designed to be smaller in order to slow down the flow rate of the aerosol-generating matrix. The lead, also known as the pitch, is the linear distance traveled axially when the helical section 222 moves one revolution.

[0059] It is understandable that the spiral portion 222 can be a spiral blade, that is, the radial dimension of the spiral blade in the column 221 is relatively large, which is beneficial for accommodating more aerosol generation matrix and extending the service life of the anti-microphone failure structure 22. Alternatively, the spiral portion 222 can also be a spiral protrusion, the radial dimension of the spiral protrusion in the column 221 is relatively small.

[0060] The suspension part 223 is provided on the column 221. It can be understood that the suspension part 223 can be integrally formed with the column 221, or the suspension part 223 can be fixed to the column 221 by means of bonding, snap-fitting, welding, interference fit, fastener connection, etc.

[0061] The suspension part 223 is suspended in the negative pressure channel 211, which can be understood as the suspension part 223 being located at or near the upper end of the column 221.

[0062] The suspension part 223 has a clearance channel 224 for the aerosol generating matrix to drip onto the spiral part 222. It can be understood that the spiral part 222 is located below the suspension part 223, and the aerosol generating matrix drips onto the spiral part 222 through the clearance channel 224.

[0063] Among them, the anti-microphone failure structure 22 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 22.

[0064] The beneficial effects of the anti-microphone failure structure 22 provided in this application embodiment are as follows: After the anti-microphone failure structure 22 is installed in the negative pressure channel 211, during suction, the airflow can spiral into the whole machine air passage on the spiral part 222, ensuring smooth suction; during the suction interval, the aerosol generation matrix drips onto the spiral part 222 through the avoidance channel 224, thereby increasing the flow distance of the aerosol generation matrix and minimizing the dripping of the aerosol generation matrix onto the microphone deformation part 411, thus ensuring the counting function of the microphone 43. Since the anti-microphone failure structure 22 is suspended in the negative pressure channel 211 by the suspension part 223, it is convenient to disassemble and assemble the anti-microphone failure structure 22 in the negative pressure channel 211. After a period of use, the anti-microphone failure structure 22 can be disassembled and cleaned.

[0065] It should be noted that aerosol-generating matrices typically have high viscosity and are not easily flowable.

[0066] In some other embodiments, please refer to Figure 1 , Figure 4 and Figure 7 The spiral portion 222 is provided with a baffle 2221 at the end away from the suspension portion 223 to block the aerosol generation matrix. The end of the spiral portion 222 away from the suspension portion 223 is the lower end of the spiral portion 222.

[0067] It is understandable that the baffle 2221 can be integrally formed on the spiral part 222, or the baffle 2221 can be fixed on the spiral part 222 by means of bonding, snap-fitting, welding, interference fit, fastener connection, etc.

[0068] Optionally, the baffle 2221 extends radially along the column 221, with one end connected to the outer circumferential surface of the column 221 and the other end located at the edge of the spiral portion 222. It can be understood that when the edge of the spiral portion 222 abuts against the wall of the negative pressure channel 211, the aerosol generating matrix is ​​blocked on the spiral portion 222. When there is a gap 23 between the edge of the spiral portion 222 and the wall of the negative pressure channel 211, the blocked aerosol generating matrix can drip through the gap 23 into the annular recess 412 of the microphone silicone 41. Since the annular recess 412 is far from the center of the microphone deformation portion 411, the aerosol generating matrix dripping into the annular recess 412 has almost no effect on the deformation of the microphone deformation portion 411.

[0069] Based on the above solution, the baffle 2221 can block the aerosol generation matrix flowing to the lower end of the spiral section 222, thereby extending the service life of the heated non-combustible appliance 100.

[0070] In other embodiments, please refer to Figure 5 The spiral portion 222 has a groove 2222 for storing the aerosol generation matrix at the end away from the suspension portion 223. The end of the spiral portion 222 away from the suspension portion 223 is the lower end of the spiral portion 222.

[0071] Optionally, the groove 2222 extends radially along the column 221, and one end of the groove 2222 is blocked by the outer peripheral surface of the column 221. It can be understood that when the edge of the spiral portion 222 abuts against the wall of the negative pressure channel 211, the other end of the groove 2222 is blocked by the wall of the negative pressure channel 211, meaning the aerosol generating matrix is ​​stored within the groove 2222. When there is a gap 23 between the edge of the spiral portion 222 and the wall of the negative pressure channel 211, the aerosol generating matrix stored in the groove 2222 can drip through the other end of the groove 2222 and the gap 23 into the annular recess 412 of the microphone silicone 41.

[0072] Based on the above scheme, the groove 2222 can store the aerosol generation matrix flowing to the lower end of the spiral part 222, so as to extend the service life of the heated non-combustible appliance 100.

[0073] Please refer to Figure 3 In some embodiments, the suspension part 223 includes a plurality of suspension arms 2231, which are arranged at intervals along the circumference of the column 221, and a clearance passage 224 is formed between two adjacent suspension arms 2231.

[0074] It is understood that the suspension arms 2231 can be two, three, four, or five or more, and correspondingly, the clearance passages 224 can be formed in two, three, four, or five or more.

[0075] Multiple suspension arms 2231 are arranged at intervals along the circumference of the column 221. It can be understood that the interval between two adjacent suspension arms 2231 can be the same or different.

[0076] It is understood that the suspension arm 2231 can be a straight arm or an arc-shaped arm. When the suspension arm 2231 is a straight arm, the clearance passage 224 is fan-shaped, wherein the cross-section of the suspension arm 2231 can be rectangular, circular, elliptical, etc.

[0077] Based on the above technical solution, the anti-microphone failure structure 22 is suspended in the negative pressure channel 211 by multiple suspension arms 2231, which has good stability. Moreover, an obstacle avoidance channel 224 is directly formed between two adjacent suspension arms 2231, eliminating the need for additional processing of the obstacle avoidance channel 224; at the same time, the obstacle avoidance channel 224 formed between two adjacent suspension arms 2231 is relatively large, which is conducive to airflow and ensures smooth suction.

[0078] In some embodiments, a plurality of suspension arms 2231 are arranged at uniform intervals along the circumference of the column 221.

[0079] For example, there are four suspension arms 2231, which are evenly spaced along the circumference of the column 221, that is, the angle between the center lines of two adjacent suspension arms 2231 is 90°; or, there are three suspension arms 2231, which are evenly spaced along the circumference of the column 221, that is, the angle between the center lines of two adjacent suspension arms 2231 is 120°.

[0080] Based on the above technical solution, the uniformity of force distribution during suspension of the anti-microphone failure structure 22 can be guaranteed, which is beneficial to improving the stability of the anti-microphone failure structure 22 after suspension.

[0081] Please refer to Figure 4 In some embodiments, the suspension part 223 is a suspension plate with through holes forming an avoidance channel 224.

[0082] It is understood that the suspension plate can be an annular plate, for example, a circular annular plate, and the suspension plate is provided on the outer peripheral surface of the column 221; or, the suspension plate can be a flat plate, for example, a circular flat plate, and the suspension plate is provided on the end face of the column 221.

[0083] The number of through holes can be one or more. When there is only one through hole, it can be an annular hole to ensure that the aerosol generating matrix can be evenly dripped onto the spiral part 222. When there are multiple through holes, they can be arranged at intervals along the circumference of the column 221 to ensure that the aerosol generating matrix can be evenly dripped onto the spiral part 222; the shape of the through holes can be circular, elliptical, polygonal, or arc-shaped, etc.

[0084] Please refer to Figure 4 In some embodiments, the side of the suspension portion 223 facing away from the spiral portion 222 is flush with the end face of the column 221.

[0085] The side of the suspension part 223 facing away from the spiral part 222 is the upper side of the suspension part 223.

[0086] Based on the above technical solution, the suspension part 223 and the column 221 together support the plug 201 of the cigarette stick 200, ensuring the uniformity of the force on the plug 201.

[0087] In other embodiments, the side of the suspension portion 223 facing away from the spiral portion 222 may not be flush with the end face of the column 221, that is, the side of the suspension portion 223 facing away from the spiral portion 222 may be lower or higher than the end face of the column 221.

[0088] Please refer to Figure 1 and Figure 3 Optionally, the column 221 is a cylinder, and the diameter D of the column 221 is less than or equal to the width W of the helical part 222.

[0089] Based on the above technical solution, the spiral part 222 has a larger area, which is conducive to accommodating more aerosol generation matrix and extending the service life of the anti-microphone failure structure 22.

[0090] In other embodiments, the diameter D of the column 221 may be greater than the width W of the helical portion 222.

[0091] Please refer to Figure 1 , Figure 2 and Figure 7 The second aspect of this application provides a microphone failure prevention component 20, which includes a mounting base 21 and a microphone failure prevention structure 22 as described in the first aspect. The mounting base 21 has a negative pressure channel 211, and the microphone failure prevention structure 22 is suspended in the negative pressure channel 211 by a suspension part 223.

[0092] During suction, the airflow flows upward through the negative pressure channel 211, creating a negative pressure above the microphone deformation part 411, thereby deforming the microphone deformation part 411 upward.

[0093] The anti-microphone failure component 20 adopts any one or more embodiments of the above-described anti-microphone failure structure 22, and therefore has the beneficial effects of the above-described embodiments, which will not be described in detail here.

[0094] In some embodiments, a gap 23 is formed between the edge of the spiral portion 222 and the wall of the negative pressure channel 211 to facilitate airflow within the negative pressure channel 211. Part of the aerosol-generating matrix drips down from the gap 23 and eventually falls into the annular recess 412 of the microphone silicone 41. Since the annular recess 412 is far from the center of the microphone deformation portion 411, the aerosol-generating matrix dripping into the annular recess 412 has almost no effect on the deformation of the microphone deformation portion 411.

[0095] Of course, the edge of the spiral section 222 abuts against the wall of the negative pressure channel 211. It can be understood that there is no gap 23 between the edge of the spiral section 222 and the wall of the negative pressure channel 211, and the aerosol generation matrix can only flow downward along the spiral section 222.

[0096] Please refer to Figure 1 and Figure 2 In some embodiments, a support step 212 is provided in the negative pressure channel 211, and the suspension part 223 is attached to the support step 212 so that the anti-microphone failure structure 22 is suspended in the negative pressure channel 211.

[0097] It is understood that the support step 212 can be a ring step, a C-shaped step, or the support step 212 can include multiple sub-steps arranged at intervals along the circumference of the mounting base 21.

[0098] Optionally, the suspension part 223 abuts against the wall of the negative pressure channel 211 to ensure that the anti-microphone failure structure 22 is centrally arranged in the negative pressure channel 211 and will not move radially in the column 221.

[0099] In other embodiments, a support rib is protruding from the wall of the negative pressure channel 211, and the suspension part 223 overlaps the support rib so that the anti-microphone failure structure 22 is suspended inside the negative pressure channel 211. The support rib can be a ring rib or a C-shaped rib.

[0100] Please refer to Figure 6 and Figure 7The third aspect of this application provides a heat-not-burning appliance 100, which includes a housing 10, a heating element 30, a microphone assembly 40, and a microphone failure prevention component 20 as described in the second aspect. The microphone failure prevention component 20, the heating element 30, and the microphone assembly 40 are disposed within the housing 10, and the microphone failure prevention component 20 is located between the heating element 30 and the microphone assembly 40.

[0101] Alternatively, please refer to Figure 8 and Figure 9 The heating element 30 includes a tube 31 and a heating element 32. Optionally, the heating element 32 is a sheet-like structure and is located outside the tube 31. The cigarette 200 is inserted into the heating element 30 from the end away from the microphone assembly 40. After the heating element 30 heats up, it conducts heat to the cigarette 200 to achieve low-temperature baking of the cigarette 200 to generate aerosol.

[0102] The cigarette stick 200 includes a plug 201 for insertion into the mounting base 21. The plug 201 has multiple air holes 2011. During the inhalation interval, the aerosol generation matrix drips onto the spiral part 222 through the air holes 2011. Optionally, the inner wall surface of the upper part of the mounting base 21 is provided with a ring platform, and the lower end of the tube 31 of the heating element 30 is supported on the ring platform.

[0103] Alternatively, please refer to Figure 10 The microphone assembly 40 includes a microphone silicone 41, a microphone base 42, and a microphone 43. The microphone 43 is mounted on the microphone base 42, and the microphone base 42 is mounted on the microphone silicone 41. The microphone silicone 41 includes a microphone deformable portion 411 and an annular recess 412. The microphone 43 is located below the microphone deformable portion 411, and the annular recess 412 is located at the edge of the microphone deformable portion 411. The microphone 43 is used to detect the deformation of the microphone deformable portion 411 and trigger the operation of the heated non-combustible appliance 100.

[0104] Optionally, the heated non-combustible appliance 100 also includes a power supply component 50 located within the housing 10.
