Abstract

This invention discloses an oil-proof mechanism, a main unit, and an aerosol generating device. The oil-proof mechanism includes a housing and a support. The housing is used to house the microphone and has an air passage so that the microphone can communicate with the outside through the air passage. The support is disposed on the housing and has a first vent hole that communicates with both the air passage and the outside. The projection of the support in the extension direction of the air passage covers the projection of the sidewall of the air passage in the extension direction of the air passage, so that the liquefied aerosol flowing down from above the support cannot directly enter the air passage, thereby preventing the liquefied aerosol from accumulating at the microphone and allowing the microphone to maintain normal operation. The microphone's placement is unrestricted, and its installation in conjunction with other mechanisms is more flexible.

Description

Technical Field

[0001] This invention relates to the field of aerosol technology, and in particular to an oil-proof mechanism, a main unit, and an aerosol generating device. Background Technology

[0002] Aerosol generating devices heat an atomizing medium to form aerosols. The atomization process is simple, easy to operate, and leaves no residue. Aerosol generating devices typically use a microphone to sense air pressure, thereby controlling the heating of the atomizing medium based on the air pressure, making the atomization process more intelligent.

[0003] To ensure the normal operation of the microphone, it needs to be connected to the outside air through the air passage. During the process of the atomizing medium being atomized into an aerosol and sent out of the aerosol generating device, some of the aerosol may liquefy within the aerosol generating device. If the microphone is not positioned properly, the liquefied aerosol will enter the air passage and accumulate at the microphone, affecting its operation. Summary of the Invention

[0010] In one specific embodiment, the receiving member includes a cover and an air passage component. The cover is used to cover the microphone head, and the air passage component is disposed on the cover. The air passage component and the cover together form the air passage, and the second vent is formed on the side wall of the air passage component.

[0011] In one specific embodiment, the top end face area of ​​the protrusion is larger than the top end face area of ​​the air passage component.

[0012] In one specific embodiment, the oil-proof mechanism further includes a fixing member, the air passage is disposed through the fixing member, the main body is mounted on the fixing member, a first oil storage space is formed between the main body and the fixing member, the first oil storage space is connected to the first vent hole, so that the liquefied aerosol flowing down from the top of the protrusion can flow into the first oil storage space.

[0013] In one specific embodiment, a second oil storage space is formed above the main body, and the top end face of the protrusion is inclined relative to the horizontal direction so that the liquefied aerosol flowing down from the top of the protrusion can flow to the first oil storage space or the second oil storage space.

[0014] In one specific embodiment, the oil-proof mechanism further includes an oil-absorbing member disposed between the main body and the fixing member, and in at least one of the first oil storage space and the second oil storage space.

[0015] In one specific embodiment, the top of the protrusion is chamfered.

[0016] To solve the above-mentioned technical problems, another technical solution adopted by the present invention is to provide a host, including a housing, a power supply and an oil-proof mechanism as described above, wherein at least a portion of the oil-proof mechanism and the power supply are respectively disposed in the housing, and the oil-proof mechanism is located at one end of the power supply.

[0030] See Figure 1 and Figure 2 An embodiment of the oil-proof mechanism 100 of the present invention includes a receiving member 110 and a bracket 120. The receiving member 110 is used to receive a microphone 200, and the receiving member 110 forms an air passage 111 so that the microphone 200 can communicate with the outside through the air passage 111. The bracket 120 is disposed on the receiving member 110 and forms a first vent 121. The first vent 121 communicates with the air passage 111 and the outside. The projection of the bracket 120 in the extending direction of the air passage 111 is shown in the figure. The projection of the side wall of the airway 111 onto the extension direction of the airway 111, that is, the projection of the bracket 120 onto the extension direction of the airway 111, covers the cross section of the airway 111. This prevents the liquefied aerosol flowing down from above the bracket 120 from directly entering the airway 111, thus preventing the liquefied aerosol from accumulating at the microphone 200. This allows the microphone 200 to maintain normal operation, and the placement of the microphone 200 is unrestricted, making its installation more flexible in conjunction with other mechanisms.

[0031] In this embodiment, the bracket 120 includes a main body 122 and a protrusion 123. The protrusion 123 covers the receiving member 110. A first vent 121 is formed on the side wall of the protrusion 123. A second vent 112 is formed on the side wall of the receiving member 110. The second vent 112 is connected to the first vent 121 and the air passage 111 respectively, so that the air passage 111 can be connected to the outside through the first vent 121 and the second vent 112, thereby facilitating the microphone 200 to detect the air pressure.

[0032] Furthermore, the side of the first vent 121 closest to the microphone 200 is lower than the side of the second vent 112 closest to the microphone 200, and the side of the first vent 121 furthest from the microphone 200 is lower than the side of the second vent 112 furthest from the microphone 200. This better prevents liquid from flowing into the microphone 200. Even if a large amount of aerosol passes through the first vent 121 and the second vent 121, the aerosol is more likely to condense on the side wall of the accommodating member 110, and is less likely to enter the microphone 200 through the second aerosol 112 and the air passage 111.

[0033] In this embodiment, the accommodating member 110 may include a cover 113 and an air passage 114. The cover 113 is used to cover the microphone 200, and the air passage 114 is disposed on the cover 113. The air passage 114 and the cover 113 together form an air passage 111. A second vent 112 is formed on the side wall of the air passage 114. By separately arranging the cover 113 and the air passage 114 of the accommodating member 110, it is convenient to assemble the accommodating member 110 with the microphone 200.

[0034] In other embodiments, a breathable liquid-proof membrane (not shown in the figure) may also be provided on the second vent 112, which can allow the aerosol passing through the first vent 121 to condense and flow back to the outside of the air passage 114 without obstructing the passage of gas, thereby further preventing the liquefied aerosol from falling into the air passage 111.

[0035] Among them, the breathable liquid-proof membrane can be a thin film with multiple micropores. The micropores allow gas to pass through, but liquid does not easily pass through. Aerosols can condense and liquefy on the breathable liquid-proof membrane and then flow down to the outside of the air passage 114.

[0036] In this embodiment, the cover 113 can be made of a flexible material, such as silicone or rubber, which can increase the sealing between the air passage 114 and the microphone 200.

[0037] In this embodiment, the cover 113 and the air duct 114 can be an interference fit, which can further increase the sealing between the cover 113 and the air duct 114.

[0038] In other embodiments, the cover 113 and the air duct 114 may also be integrally formed, which is not limited here.

[0039] In this embodiment, the top end face area of ​​the protrusion 123 is larger than the top end face area of ​​the air passage 114, and the side wall of the air passage 114 abuts against the side wall of the protrusion 123 away from the first vent hole 121, which can further prevent the liquefied aerosol flowing down from the side wall of the protrusion 123 from entering the air passage 111 through the first vent hole 121, thereby further improving the oil-proof effect.

[0040] In this embodiment, the upper surface of the protrusion 123 may also be provided with a plurality of tiny blind holes (not shown in the figure). The blind holes can accommodate the liquefied aerosol, so that during the air intake process, the liquefied aerosol in the blind holes can be carried by the airflow to the upper heating element 202 for heating and atomization, which can save the material of the bracket 120 and also prevent the liquefied aerosol from being excessively accumulated below the first vent 121.

[0041] Furthermore, in other embodiments, the oil-proof mechanism may also include a seal (not shown in the figure), which is disposed between the side wall of the air passage 114 and the side wall of the protrusion 123 away from the first vent 121, to prevent liquid from entering the gap between the side wall of the air passage 114 and the side wall of the protrusion 123 and causing adverse effects.

[0042] In this embodiment, the oil-proof mechanism 100 also includes a fixing member 130, an air passage member 114 is disposed through the fixing member 130, the main body 122 of the bracket 120 is mounted on the fixing member 130, a first oil storage space 124 is formed between the main body 122 and the fixing member 130, the first oil storage space 124 is connected to the first vent hole 121, so that the liquefied aerosol flowing down from the top of the protrusion 123 can flow to the first oil storage space 124 for storage, and prevent the liquefied aerosol from overflowing into the air passage 111 and causing contamination to the microphone 200.

[0043] In this embodiment, a second oil storage space 125 can be formed above the main body 122 so that the liquefied aerosol flowing down from the top of the protrusion 123 can flow into the second oil storage space 125 for storage, thereby preventing the liquefied aerosol from overflowing into the air passage 111 and causing contamination to the microphone 200.

[0044] In this embodiment, a bearing step (not shown in the figure) may also be formed on the outer side wall of the air passage 114, and at least part of the main body 122 is supported on the bearing step, which facilitates the installation of the bracket 120 and the receiving member 110.

[0045] In this embodiment, the top of the protrusion 123 can be chamfered, which facilitates the flow of liquefied aerosol falling on the top of the protrusion 123 to the side wall, avoiding accumulation on the top of the protrusion 123 and contamination of other components.

[0046] In this embodiment, the air passage 114 and the fixing member 130 can be an interference fit, which can further prevent the liquefied aerosol from leaking between the air passage 114 and the fixing member 130 and improve the oil-proof effect.

[0047] In this embodiment, a first sealing ring 141 may also be provided between the air passage component 114 and the fixing component 130. The first sealing ring 141 can further prevent the liquefied aerosol from leaking between the air passage component 114 and the fixing component 130, thereby improving the oil-proof effect.

[0048] In this embodiment, the fixing member 130 can be arranged in a ring shape to facilitate the fixed connection between the host 10 and the atomizer 20.

[0049] See Figure 3 and Figure 4 Another embodiment of the oil-proof mechanism 100 of the present invention includes a receiving element 110 and a bracket 120. The structure of the receiving element 110 and the bracket 120 is similar to that of the receiving element 110 and the bracket 120 in the oil-proof mechanism 100 described above, and will not be repeated here.

[0050] The difference between this embodiment and the above embodiment is that, in this embodiment, the top end face of the protrusion 123 of the bracket 120 is inclined relative to the horizontal direction away from the first vent 121, so that at least a portion of the liquefied aerosol flowing down from the top of the protrusion 123 can flow quickly to the second oil storage space 125, thereby allowing less liquefied aerosol to flow to the side of the protrusion 123 where the first vent 121 is formed, reducing the probability of liquefied aerosol entering the air passage 111 through the first vent 121, and further improving the oil-proof effect.

[0051] See Figure 5 and Figure 6 Another embodiment of the oil-proof mechanism 100 of the present invention includes a receiving element 110 and a bracket 120. The structure of the receiving element 110 and the bracket 120 is similar to that of the receiving element 110 and the bracket 120 in the oil-proof mechanism 100 described above, and will not be repeated here.

[0052] The difference between this embodiment and the above embodiment is that, in this embodiment, the top end face of the protrusion 123 of the support 120 is inclined towards the first vent 121 relative to the horizontal direction, so that at least a portion of the liquefied aerosol flowing down from the top of the protrusion 123 can flow quickly to the first oil storage space 124, thereby allowing less liquefied aerosol to flow to the second oil storage space 125, resulting in less liquefied aerosol accumulating on the surface of the support 120, making the surface of the support 120 cleaner, and after the liquefied aerosol has accumulated in the first oil storage space 124, the second oil storage space 125 can still accommodate liquefied aerosol, resulting in high reliability.

[0053] In other embodiments, the oil-proof mechanism 100 may also include a seal (not shown in the figure), which is disposed on the main body 122 and / or the air passage 114. When the capacity of the aerosol stored in the first oil storage space 124 reaches a predetermined capacity, the seal will seal the first oil storage space 124 to prevent the liquefied aerosol or other liquids from overflowing. The user can manually open the seal to clean the liquefied aerosol in the first oil storage space 124.

[0054] In this embodiment, the oil-proof mechanism 100 also includes an oil-absorbing component 150, which is disposed between the main body 122 of the bracket 120 and the fixing component 130, and within the first oil storage space 124, which can further improve the oil absorption effect and prevent the liquefied aerosol from overflowing.

[0055] In other embodiments, the oil suction member 150 may also be disposed within the second oil storage space 125, which is not limited here.

[0056] In this embodiment, the oil-absorbing component 150 can be oil-absorbing cotton, and the oil-absorbing cotton can also be provided with through holes, which can allow air to pass through smoothly while absorbing oil, and avoid blockage by air or aerosol.

[0057] See Figure 1 , Figure 2 and Figure 7 The host computer 10 embodiment of the present invention includes a housing 300, a power supply 400, and an oil-proof mechanism 100. At least a portion of the oil-proof mechanism 100 and the power supply 400 are respectively disposed within the housing 300, and the oil-proof mechanism 100 is located at one end of the power supply 400. The structure of the oil-proof mechanism 100 is the same as described in the above embodiment of the oil-proof mechanism 100, and will not be repeated here.

[0058] This embodiment prevents the liquefied aerosol flowing down from above the bracket 120 from directly entering the air passage 111, thus preventing the liquefied aerosol from accumulating at the microphone 200. This allows the microphone 200 to maintain normal operation, and its placement is unrestricted, making its installation with other mechanisms more flexible. In this embodiment, a second sealing ring 142 can also be provided between the fixing member 130 and the housing 300. The second sealing ring 142 can further prevent the liquefied aerosol from leaking between the fixing member 130 and the housing 300, improving the oil-proof effect.

[0059] In this embodiment, the main unit 10 may further include an air regulating component 510. A first air inlet (not shown in the figure) is formed on the fixing component 130, and a second air inlet (not shown in the figure) is formed on the air regulating component 510 that can communicate with the first air inlet. The air regulating component 510 can move or rotate relative to the fixing component 130 to adjust the size of the first air inlet 131, which can accurately control the amount of air entering the housing 300. When the size of the first air inlet 131 is adjusted to 0, it can also prevent dirt from entering the fixing component 130 and prevent oil leakage.

[0060] In this embodiment, the host 10 may also include an air regulating component sealing ring 511, which is disposed between the air regulating component 510 and the fixing component 130 to increase the sealing between the air regulating component 510 and the fixing component 130.

[0061] In this embodiment, the fastener 130 can be fixedly connected to the housing 300 via the fastener 520, which can be a screw or the like.

[0062] In other embodiments, the fastener 130 may also be fixedly connected to the housing 300 by other means such as pasting, welding, or snap-fitting, and no limitation is made here.

[0063] In this embodiment, the host 10 also includes a microphone control board 530, which is disposed inside the housing 300, and the microphone 200 is disposed on the microphone control board 530.

[0064] In this embodiment, the host 10 may further include an insulating sheet 540, which is disposed at both ends of the power supply 400 to isolate and insulate the power supply 400 from other components.

[0065] In this embodiment, the host 10 may also include a power supply sleeve 410, which is used to house the power supply 400 and can protect the power supply 400.

[0066] In this embodiment, the host 10 may also include a cover 550, which is disposed on the end of the housing 300 away from the oil-proof mechanism 100. The cover 550 is used to cover the power interface (not shown in the figure) and can play a protective role for the power interface.

[0067] In this embodiment, the host 10 may also include a flexible pad 560, which is disposed at the end of the cover 550 away from the power supply 400, so that the host 10 can be placed on the support platform (not shown in the figure).

[0068] Among them, the flexible pad 560 can be a silicone pad, a rubber pad, etc.

[0069] See Figure 1 , Figure 2 and Figure 8 The aerosol generating device of the present invention includes a main unit 10 and an atomizer 20. The main unit 10 is connected to the atomizer 20 and is used to supply power to the atomizer 20. The structure of the main unit 10 is described in the above embodiment of the main unit 10, and will not be repeated here.

[0070] This embodiment prevents the liquefied aerosol flowing down from above the bracket 120 from directly entering the airway 111, thus preventing the liquefied aerosol from accumulating at the microphone 200. This allows the microphone 200 to maintain normal operation, and the placement of the microphone 200 is unrestricted, making its installation in conjunction with other mechanisms more flexible.

[0071] In this embodiment, the atomizer 20 includes a base 201, a heating element 202 disposed within the base 201, and a ventilation pipe 203 passing through the base 201. The base 201 is used to be fixedly connected to the fixing member 130, and the base 201 forms an accommodating space 204 communicating with the ventilation pipe 203. The accommodating space 204 is used to accommodate the atomizing matrix (not shown in the figure). The heating element 202 is disposed at one end of the base 201 near the host 10, and the ventilation pipe 203 is disposed at one end of the base 201 away from the heating element 202. The heating element 202 is used to receive power from the host 10 to heat the atomizing matrix, thereby forming an aerosol. The aerosol is output through the ventilation pipe 203.

[0072] In this embodiment, the atomizer 20 may also include a mouthpiece 205, which is connected to the air tube 203 for use by the user to inhale.

[0073] In this embodiment, the atomizer 20 may also include a mouthpiece cover 206, which covers the mouthpiece 205 and serves to prevent dust.
